This application is the U.S. National Phase, under 35 U.S.C. § 371, of PCT/EP2018/069390, filed Jul. 17, 2018; published as WO 2019/020434 A1 on Jan. 31, 2019, and claiming priority to DE 10 2017 212 987.5, filed Jul. 27, 2017, the disclosures of which are expressly incorporated herein in their entireties by reference.
The present invention relates to a sheet-fed printing press.
A number of different printing methods are used in printing presses. Non-impact printing (NIP) methods are understood as printing methods that do not require a fixed, that is to say, a physically unalterable printing forme. Printing methods of this type are able to produce different printed images in each printing operation. Examples of non-impact printing methods include ionographic methods, magnetographic methods, thermographic methods, electrophotography, laser printing, and in particular inkjet printing methods. Such printing methods typically involve at least one image producing device, for example at least one print head. In the inkjet printing method, such a print head is configured, for example, as an inkjet print head and has at least one and preferably a plurality of nozzles, by means of which at least one printing fluid, for example in the form of ink droplets, can be transferred selectively onto a printing substrate. Alternative printing methods, such as intaglio printing, planographic printing, offset printing and letterpress printing methods, in particular flexographic printing, use fixed printing formes. Depending upon the size of the print run and/or other requirements such as print quality, a non-impact printing method or a printing method that uses a fixed printing forme may be preferable.
The precise matching of a printed image on the front and back sides of a printing substrate that is printed on both sides is referred to as register (DIN 16500-2). In multicolor printing, the merging of individual printed images of different colors in precise alignment to form a single image is referred to as color registration (DIN 16500-2). In inkjet printing, as with other processes, appropriate measures must be implemented to maintain color registration and/or register. In particular, it is important for the relative position between print head and printing substrate to be known and/or kept constant. Registration is also referred to as color register. In the following, the term register mark will therefore also be understood as referring to a registration mark, i.e. a mark for checking color registration or color register.
Sheet-fed printing presses are known. However, conventional transport systems cannot always be used with particularly thick sheets.
From DE 10 2015 111525 A1, a sheet-fed printing press is known, which operates according to the principle of offset printing and which is equipped with additional inkjet printing elements that have print heads and dryers, which are optionally arranged so as to be movable. Drives for transporting sheets are not described.
From DE 102 27241 A1, a drive system of a sheet-fed printing press is known, in which drive control units act as module control units.
From DE 10 2011 088776 B3, a printing press that has inkjet print heads and dryers is known. The transport of printing substrate and drives provided for said transport are described only in connection with a web-fed printing press.
EP 0669208 A1 discloses a sheet-fed printing press having drive motors for cylinders and the capability of positioning said drives axially.
EP 0615941 A1 discloses a sheet-fed printing press having individually driven acceleration means.
From DE 697 21715 T2, a method and a device are known, in which mailpieces, in particular postcards, are singulated and fed to an inkjet print head. The mailpieces are accelerated to a first speed by a primary acceleration means and are accelerated to a second speed by a secondary acceleration means. The two acceleration means are driven by a common drive. A motor controller controls this drive as well as a drive that transports the mailpieces past the print head module. The mailpieces are decelerated by the secondary acceleration means as needed in order to increase the gap between a mailpiece and the mailpiece that precedes it. Because of the common drive, decelerating this secondary acceleration means also necessarily decelerates the first acceleration means.
US 2001/0022422 A1 and US 2013/0216291 A1 each disclose a method and a copying machine by which paper sheets are removed from a pile from above, singulated, and fed to a print position.
US 2002/0180138 A1 discloses a method and a device in which checks are singulated and marked. A primary acceleration means is operated more slowly than a secondary acceleration means. The checks are decelerated or accelerated by the secondary acceleration means as needed in order to adjust the gap between a check and the check that precedes it. At the same time, the primary acceleration means is decelerated or accelerated in the same ratio.

From WO 2014/047513 A2, a non-impact sheet-fed printing press having a conveyor belt and coating positions is known.
U.S. Pat. No. 4,841,306 A discloses a non-impact printing machine for textiles, which likewise has a conveyor belt. The respective conveyor belt is mounted in a frame. Print heads are connected to or removed from said frame by means of replaceable sub-frames. Mechanisms are disclosed, with which the sub-frames are connected to the frames.
From DE 10 2010 060 405 A1, a non-impact printing press is known, in which the position of print heads in sub-frames can be adjusted.
The object of the present invention is to devise a sheet-fed printing press.
The object is achieved according to the invention by the provision of a sheet-fed printing press which has at least one coating unit that is configured as a non-impact coating unit. The sheet-fed printing press has at least one conveyor belt which extends, with at least one conveying section of its circulation path, parallel to a transport direction, along a section of a transport path provided for sheets. Along the conveying section of the at least one conveyor belt, at least one coating position of the at least one coating unit is located. The at least one coating unit has at least one print head. The at least one print head is arranged connected to at least one first frame of the at least one coating unit. The at least one conveyor belt is arranged connected, via at least one deflection device and at least one radial bearing, to at least one second frame. Apart from at least one installation surface that is different from the at least one first frame and the at least one second frame, the at least one first frame is arranged in contact with the second frame at most via flexible connections.
A sheet processing machine is configured as a sheet-fed printing press. The sheet processing machine is preferably configured as a sheet processing machine for processing corrugated cardboard sheets, i.e., as a corrugated cardboard sheet processing machine. Further preferably, the sheet processing machine is configured as a sheet-fed printing press for coating and in particular for printing corrugated cardboard sheets, i.e., as a sheet-fed corrugated cardboard printing press. The processing machine configured as a sheet-fed printing press preferably has at least one and more preferably at least two units configured as modules. The at least one module and more preferably each of the at least two modules preferably has at least one drive dedicated uniquely to it. At least one of the at least two modules is preferably configured as a coating module.
The processing machine configured as sheet-fed printing press is characterized in that the sheet-fed printing press has at least one coating unit configured as a non-impact coating unit, and in that the sheet-fed printing press has at least one conveyor belt that extends with at least one conveying section of its circulation path parallel to a transport direction along a section of a transport path provided for sheets. At least one coating position of at least one coating unit of the sheet-fed printing press is arranged along the conveying section of the at least one conveyor belt, more preferably multiple coating positions. The at least one coating unit has at least one print heads, the at least one print head being arranged connected to at least one first frame of the at least one coating unit.
The at least one conveyor belt is arranged connected to at least one second frame via at least one deflection means and at least one radial bearing.

Such a connection is therefore understood not necessarily as an adhesive and/or frictional and/or positive connection, but rather as direct contact or contact that is imparted indirectly via other components.
Such a flexible connection, in particular such a mechanically flexible connection, is formed, for example, by at least one or more in particular mechanically flexible components and/or by at least one or more in particular mechanically flexible assemblies. In particular, such flexible, in particular mechanically flexible connections are understood as an interposition of at least one in particular mechanically flexible component and/or an interposition of at least one in particular mechanically flexible assembly. Such mechanically flexible connections, in particular, are supply lines for power and/or data and/or gas and/or gas mixtures and/or liquids, for example, and/or are reversibly deformable bodies or assemblies that have deformable bodies, for example. Deformable bodies also include, for example, elastic bumpers and/or rubber bumpers and/or articulated connections. The at least one print head can thereby be decoupled particularly effectively from any vibrations that might be induced by the at least one conveyor belt and/or the deflection means thereof and/or the drive thereof.

In an alternative or additional refinement, the processing machine preferably configured as a sheet-fed printing press is preferably characterized in that an exposure zone of the drying system or drying device of the at least one additional of the at least two modules is located downstream of an application position of said at least one additional of the at least two modules with respect to the transport path provided for sheets.
In an alternative or additional refinement, the processing machine preferably configured as a sheet-fed printing press is preferably characterized in that the at least one non-impact coating module is equipped with at least two receiving units, identical in construction with respect to at least one coupling device and arranged in succession along a transport path provided for sheets, each receiving unit being configured for the optional accommodation of a standard assembly, each assembly being embodied as at least one print head assembly or as at least one dryer assembly.

Like other sheet processing machines of modular construction, this machine has the advantage, in particular, that the units of the sheet processing machine configured as modules allow a cost-effective and particularly variable configuration and subsequent expansion of processing machines.
In an alternative or additional refinement, the processing machine preferably configured as a sheet-fed printing press is preferably characterized in that it has a transport path provided for the transport of sheets, and in that for a plurality of the modules of the processing machine, preferably configured as a sheet-fed printing press, more preferably for at least three and even more preferably for all of said modules, a respective section of the transport path provided for the transport of sheets, which section is defined by the respective module, has a minimum radius of curvature of at least 2 meters and/or has a direction over the entire region of the respective module that deviates no more than 30° from at least one horizontal direction. This allows even sheets of particularly great thickness that are relatively inflexible to be processed, in particular.

In an alternative or additional refinement, the processing machine preferably configured as a sheet-fed printing press is preferably characterized in that each module of the processing machine preferably configured as a sheet-fed printing press has at least one drive dedicated uniquely to it, and/or in that with the exception of an optionally provided feeder module and/or with the exception of an optionally provided delivery module, for all of the modules of the processing machine preferably configured as a sheet-fed printing press, a respective section of the transport path defined by the respective module and provided for the transport of sheets has a minimum radius of curvature of at least 2 meters and/or has a direction over the entire region of the respective module that deviates no more than 30° from at least one horizontal direction.
In an alternative or additional refinement, the processing machine preferably configured as a sheet-fed printing press is preferably characterized in that drive control systems and/or drive controllers of the individual modules can be operated individually and independently of one another, and/or in that the individual modules of the processing machine are and/or can be operated synchronized with one another with respect to their drives, and/or in that the individual modules of the processing machine are and/or can be operated synchronized with one another, at least with respect to their drives, by means of at least one electronic master axis.

More preferably, the at least one unit for aligning sheets with respect to the transverse direction has at least one lateral stop, in particular fixed in place while the sheet processing machine is in operation, and/or at least one side lay mark, in particular fixed in place while the sheet processing machine is in operation, and even more preferably at least two such lateral stops and/or at least two such side lay marks.
In an alternative or additional refinement, the processing machine preferably configured as a sheet-fed printing press is preferably characterized in that it has at least three modules, and each of at least two of the modules has at least one transfer means that serves to facilitate or carry out the transport of sheets between the module in question and at least one other module, and/or in that a section of a transport path provided for sheets, which is defined by the module in question, begins at a respective intake height of the module in question and/or ends at a respective outlet height of the module in question, and for a plurality of modules of the processing machine, the respective intake height of the module in question deviates no more than 5 cm from the same first standard height and/or the respective outlet height of the module in question deviates no more than 5 cm from the same first standard height, and/or the respective intake height of the module in question deviates no more than 5 cm from the respective outlet height of the module in question.

Exemplary embodiments of the invention are illustrated in the set of drawings and will be described in greater detail below.
In the drawings:
In the foregoing and in the following, the term coating medium or printing fluid refers to inks and printing inks, but also to primers, finish coatings, and pasty materials. Printing fluids are preferably materials that are and/or can be transferred by means of a processing machine 01, in particular a printing press 01, or at least one coating unit 400; 600; 800 of the processing machine 01, in particular at least one printing unit 600 of the printing press 01, onto a substrate 02, in particular a printing substrate 02, thereby forming a texture, preferably in finely structured form and/or not merely over a large area, which is preferably visible and/or sensorially perceptible and/or mechanically detectable on the substrate 02, in particular the printing substrate 02. Inks and printing inks are preferably solutions or dispersions of at least one colorant in at least one solvent. Suitable solvents include water and/or organic solvents, for example. Alternatively or additionally, the printing fluid may be embodied as printing fluid that is cured under UV light. Inks are relatively low-viscosity printing fluids and printing inks are relatively high-viscosity printing fluids. Inks preferably contain no binding agent or relatively little binding agent, whereas printing inks preferably contain a relatively large amount of binding agent, and further preferably contain additional auxiliary agents. Colorants may be pigments and/or dyes, with pigments being insoluble in the application medium, whereas dyes are soluble in the application medium.
In the interest of simplicity, in the foregoing and in the following—unless otherwise explicitly distinguished and specified—the term “printing ink” is understood to refer to a liquid or at least flowable fluid colorant to be used for printing in the printing press, and is not limited merely to the higher viscosity fluid colorants more frequently associated colloquially with the expression “printing ink” for use in rotary printing presses, but in addition to these higher viscosity fluid colorants particularly also includes lower viscosity fluid colorants such as “inks”, in particular inkjet inks, but also powdered fluid colorants, such as toners, for example. Thus in the foregoing and in the following, when printing fluids and/or inks and/or printing inks are mentioned, this also includes colorless finish coatings. In the foregoing and in the following, when printing fluids and/or inks and/or printing inks are mentioned, this also preferably includes, in particular, means for pretreating (priming or precoating) the printing substrate 02. The term coating medium may be understood as synonymous with the term printing fluid.
A processing machine 01 is preferably configured as a printing press 01. Processing machine 01 is preferably configured as a sheet processing machine 01, i.e. as a processing machine 01 for processing sheet-format substrate 02 or sheets 02, in particular sheet-format printing substrate 02. Processing machine 01 is further preferably configured as a corrugated cardboard sheet processing machine 01, i.e. as a processing machine 01 for processing sheet-format substrate 02 or sheets 02 of corrugated cardboard, in particular sheet-format printing substrate 02 made of corrugated cardboard. More preferably, processing machine 01 is configured as a sheet-fed printing press 01, in particular as a sheet-fed corrugated cardboard printing press 01, i.e., as a printing press 01 for coating and/or printing of sheet-format substrate 02 or sheets 02 of corrugated cardboard, in particular sheet-format printing substrate 02 made of corrugated cardboard. For example, printing press 01 is configured as a printing press 01 that operates according to a non-impact printing method and/or as a printing press 01 that operates according to a printing method requiring printing formes. Preferably, printing press 01 is configured as a non-impact printing press 01, in particular as an inkjet printing press 01 and/or as a flexo printing press 01. The printing press comprises at least one flexo coating unit 400; 600; 800, for example. Alternatively or additionally, coating machine 01 preferably includes at least one non-impact coating unit 400; 600; 800, in particular jet coating unit 400; 600; 800 or inkjet coating unit 400; 600; 800.
Unless otherwise explicitly stated, in this context the term sheet-format substrate 02, in particular, a printing substrate 02, specifically sheet 02, refers, in principle, to any flat substrate 02 in the form of sections, i.e. including panel-shaped or board-shaped substrates 02, i.e. including panels or boards. The sheet-format substrate 02 or the sheet 02 so defined is made, for example, of paper or cardboard, i.e. in the form of paper or cardboard sheet, or is composed of sheets 02, panels, or optionally boards made of plastic, cardboard, glass, or metal. More preferably, the substrate 02 is corrugated cardboard 02, in particular corrugated cardboard sheets 02. The thickness of a sheet 02 is preferably understood as a dimension orthogonally to the largest surface area of the sheet 02. This largest surface area is also called the main surface area. The thickness of sheet 02 is, for example, at least 0.1 mm, more preferably at least 0.3 mm and even more preferably at least 0.5 mm. With corrugated cardboard sheets 02 in particular, even significantly greater thicknesses are common, for example at least 4 mm or even 10 mm or more. Corrugated cardboard sheets 02 are relatively stable and therefore not very flexible. Appropriate adjustments to processing machine 01 therefore facilitate the processing of sheets 02 of significant thickness.

Processing machine 01 preferably comprises transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 at one or more locations, said transport means preferably being configured as suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011, in particular as a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 and/or as a suction box belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 and/or as a roller suction system 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 and/or as a suction roller 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. Such suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 are preferably used for moving sheets 02 forward in a controlled manner. For this purpose, a relative vacuum pressure is preferably used to pull and/or push the sheets 02 against at least one transport surface 718, and a transporting movement of sheets 02 is preferably generated by a corresponding, in particular circulating, movement of the at least one transport surface 718. The vacuum pressure is in particular a vacuum pressure relative to an ambient pressure, in particular relative to an atmospheric pressure.
A suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is therefore preferably understood as a system that comprises at least one movable transport surface 718, which serves in particular as a counterpressure surface 718 and is movable, for example, at least partially, at least in the transport direction T. Suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 further comprises at least one vacuum pressure chamber 719, which is connected by means of a suction line 721 to at least one vacuum pressure source 733. Vacuum pressure source 733 includes a blower 733, for example. The at least one vacuum pressure chamber 719 has at least one suction inlet 722, which serves to draw the sheets 02 in by suction. Depending upon the embodiment of the suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 and the size of sheets 02, the sheets 02 are thereby sucked into a position in which they seal off the at least one suction inlet 722 or are merely sucked against a counterpressure surface 718 such that ambient air is still able to pass along sheet 02 and into suction inlet 722. Transport surface 718 has one or more suction openings 723, for example. Suction openings 723 preferably serve to convey a vacuum pressure from suction inlet 722 of vacuum pressure chamber 719 to the transport surface 718, in particular without pressure losses or with very low pressure losses. Alternatively or additionally, suction inlet 722 acts on sheets 02 in such a way that said sheets are sucked against transport surface 718, even though transport surface 718 has no suction openings 723. At least one deflection means 724 is provided, for example, which directly or indirectly ensures a circulating movement of the at least one transport surface 718. The at least one deflection means 724 and/or the transport surface 718 preferably is and/or can be autonomously driven, in particular to provide for movement of the sheets 02.
A first embodiment of a suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. In this context, a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is understood as a system having at least one flexible conveyor belt 718; 726, which serves as a transport surface 718. The at least one conveyor belt 718; 726 is preferably deflected by deflection means 724 configured as deflection rollers 724 and/or deflection cylinders 724 and/or is preferably closed, so that continuous circulation is possible. The at least one conveyor belt 718; 726 preferably has a multiplicity of suction openings 723. Over at least a portion of its circulation path, the at least one conveyor belt 718; 726 preferably covers the at least one suction inlet 722 of the at least one vacuum pressure chamber 719. In that case, vacuum pressure chamber 719 is more preferably connected to the ambient environment and/or to sheets 02 only via the suction openings 723 of the at least one conveyor belt 718; 726. Preferably, support means are provided, which prevent the at least one conveyor belt 718; 726 from being drawn too far, or at all, into the vacuum pressure chamber 719 and/or which ensure that transport surface 718 takes on a desired shape, for example forming a planar surface, at least in the region in which its suction openings 723 are connected to vacuum pressure chamber 719. A circulating movement of the at least one conveyor belt 718 then results in a forward movement of transport surface 718, during which sheets 02 are held securely on transport surface 718 precisely in the region in which they are opposite the suction inlet 722, which is covered by the at least one conveyor belt 718; 726 with the exception of suction openings 723.
A second embodiment of a suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is a suction box belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. A suction box belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is understood as a system that comprises a plurality of suction boxes 718; 727, each having an outer surface 718 that serves as a transport surface 718. Each of the suction boxes 718; 727 preferably has at least one suction chamber 728. The respective suction chamber 728 is preferably open outward in one direction through at least one flow opening 729. This at least one flow opening 729 preferably serves to conduct a vacuum pressure from the vacuum pressure chamber 719 into the respective suction chamber 728. The at least one flow opening 729 is positioned laterally, for example, or is positioned such that it faces at least intermittently in or opposite a vertical direction V. Each of the suction boxes 718; 727 preferably has a multiplicity of suctioning openings 723. The suction boxes 718; 727 are preferably configured as relatively rigid. The suction boxes 718; 723 are preferably connected to one another flexibly, in particular via at least one connecting means 731. The at least one connecting means 731 is configured, for example, as a tensioning means 731, in particular a belt 731 or band 731, more preferably as a fully circumferential and/or endless connecting means 731. All of the suction boxes 718; 727 are attached, for example, to the same at least one connecting means 731. Alternatively, adjacent suction boxes 718; 717 may also be connected to one another in pairs. The connections result in a suction box belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. This suction box belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011, in particular a subset of the suction boxes 718; 727, covers the at least one suction inlet 722 of the at least one vacuum pressure chamber 719, preferably in at least one part of a circulation path of the suction box belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. Further preferably, vacuum pressure chamber 719 is then connected to the ambient environment and/or to sheets 02 only via the suction openings 723 of suction boxes 718; 727.
The at least one suction box belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is preferably deflected by deflection means 724 configured as deflection rollers 724 and/or deflection cylinders 724 and is preferably closed so that endless circulation is possible. Deflection means 724 cooperate directly with tensioning means 731 and/or drive said means, for example. Each of the suction boxes 718; 727 preferably has a planar transport surface 718, so that a plurality of suction boxes arranged one behind the other form a correspondingly larger planar transport surface 718. A circulating movement of suction boxes 718; 272 then results in a forward movement of the transport surface 718, during which said sheets 02 are held securely on the transport surface 718 precisely in the region in which said sheets are in contact with the suction boxes 718; 722, which are connected tightly to the suction inlet 722. Preferably, guide means 732 are provided, which serve to restrict the movement of the suction boxes 718; 727 to defined regions.
A third embodiment of a suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is a roller suction system 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. A roller suction system 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is understood as a system in which the at least one transport surface 718 is composed of at least parts of lateral surfaces 718 of a multiplicity of transport rollers 724 and/or transport cylinders 724. The transport rollers 724 and/or transport cylinders 724 each form closed parts of the transport surface 718 that circulate by rotation. The roller suction system 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 preferably has a multiplicity of suction inlets 722. These suction inlets 722 are preferably arranged at least between adjacent transport rollers 724 and/or transport cylinders 724.
At least one covering mask 734 is provided, for example, which preferably acts as a boundary of the vacuum pressure chamber 719. Covering mask 734 preferably comprises the multiplicity of suction inlets 722. Covering mask 734 preferably forms a substantially planar surface. The transport rollers 724 and/or transport cylinders 724 are preferably arranged such that they are intersected by this planar surface and more preferably protrude only slightly, for example only a few millimeters, beyond this planar surface, in particular in a direction facing away from the vacuum pressure chamber 719. In that case, the suction inlets 722 are preferably configured in the form of a frame, each surrounding at least one of the transport rollers 724 and/or transport cylinders 724. In other words, this means that the transport rollers 724 and/or transport cylinders 724 preferably protrude slightly, for example only a few millimeters, through the suction inlets 722 that penetrate the covering mask 734 which delimits the vacuum pressure chamber 719. Alternatively, some or all of the transport rollers 724 and/or transport cylinders 724 protrude through openings in the covering mask 734 that have no connection to the vacuum pressure chamber 719. In that case, such openings are provided in addition to separate suction inlets 722, for example. A rotating movement of transport rollers 724 and/or transport cylinders 724 then results in a forward movement of the parts of the transport surface 718, with sheets 02 being held securely on the transport surface 718 precisely in the region in which they are opposite the suction inlet 722. One advantage of roller suction systems 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is high wear resistance, for example. Of concern, however, is a risk of poorer adhesion between transport rollers 724 and sheets 02, a potentially less accurate infeed, and/or a risk of damage to the contacting surface of sheets 02 due to relatively small, linear bearing surfaces.
A fourth embodiment of a suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is at least one suction roller 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. A suction roller 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is understood here as a roller whose lateral surface serves as a transport surface 718 and has a multiplicity of suction openings 723, and which has at least one vacuum pressure chamber 719 in its interior, which is connected to at least one vacuum pressure source 733, for example by means of a suction line 721.
At least one cleaning system is preferably provided, which is used for cleaning the respective transport surface 718 of the respective suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. Said cleaning system may be configured as a vacuum system and/or a blower system and/or a stripping system, for example, and/or preferably serves to remove bits of paper and/or dust. The cleaning system is located aligned toward a side of the suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 that faces away from the transport path designated for sheets 02 and/or aligned toward the respective transport surface 718.
Sheet processing machine 01 is preferably characterized in that at least one cleaning system for cleaning at least one transport means 111; 117; 119 of the substrate supply system 100 is provided, and/or in that at least one cleaning system for cleaning at least one transport means 411; 417; 611; 617; 811; 817 of a coating unit 400; 600; 800, in particular a non-impact coating unit 400; 600; 800, is provided, and/or in that at least one cleaning system for cleaning at least one transport means 211 of the preprocessing system 200 is provided, and/or in that at least one cleaning system for cleaning at least one transport means 561 of the post-processing system 550 is provided, and/or in that at least one cleaning system for cleaning at least one transport means 711 of the transport system 700 is provided, and/or in that at least one cleaning system for cleaning at least one transport means 911 of the shaping system 900 is provided, and/or in that at least one cleaning system for cleaning at least one transport means 1011 of the substrate delivery system 1000 is provided.
Regardless of the embodiment of the respective suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011, at least two arrangements of the respective suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 are possible, which will be described in the following.

A transfer point from an upper suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 to a lower suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 or from a lower suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 to an upper suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 can be formed, for example, by the transport path provided for sheets 02 being delimited, at least in a partial region, by both a lower suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 and an upper suction transport means 111; 117. The suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 whose zone of action ends later as viewed in the transport direction T then determines whether sheets 02 will be transported beyond the transfer point in a suspended or a supported position.
Regardless of whether the suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 is embodied as a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 and/or as a suction box belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 and/or as a roller suction system 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011, the at least one vacuum chamber 719 is and/or can be subdivided with respect to the transverse direction A into multiple parts, for example, which preferably are and/or can be sealed off from one another, and/or which can be supplied individually with vacuum pressure. This enables the system to adjust to sheets 02 of different widths, without requiring the intake of an unnecessarily large amount of air. Preferably, however, the suction inlets 722 and/or the suction openings 723 are selected as small enough that a volume of air passing through these openings is very small, even when they are not covered by a sheet 02. In that case, adjustment to the width of the sheets 02 can be dispensed with.
The following are additional configurations for suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. These configurations are particularly advantageous and are preferred in the case of suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 configured in accordance with the first embodiment as a respective suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. As long as no contradictions arise, however, the configurations also apply to other embodiments of suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. Sheet-fed printing press 01 preferably has at least one suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 configured as a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. This at least one suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 preferably has at least one, in particular flexible conveyor belt 718; 726, which extends with at least one conveying section of its circulation path parallel to the transport direction T along a section of the transport path provided for sheets 02, in particular over a transport length. The at least one conveyor belt 718; 726 preferably has a multiplicity of suction openings 723. The conveying section is stationary, even when conveyor belt 718; 726 is moving, and in particular is not permanently assigned to any component of conveyor belt 718; 726.
At least two, more preferably at least three, even more preferably at least five, and more preferably still at least ten vacuum pressure chambers 719, which in particular are and/or can be separated from one another with respect to the transport direction T and each of which has at least one suction inlet 722, are preferably arranged one behind the other along the transport path provided for sheets 02. Such separation is understood to include fluidic separation, in particular. This separation is preferably complete, in particular such that a connection exists at most via lines that are connected to a vacuum pressure source 733 and/or via the suction openings 723 of conveyor belt 718; 726 and an ambient atmosphere. The conveying section of the circulation path of the at least one conveyor belt 718; 726 preferably covers at least one suction inlet 722 of some, more preferably of all of these vacuum pressure chambers 719, arranged one behind the other, at least partially, in particular with the exception of respective suction openings 723. This means that multiple vacuum pressure chambers 719 that influence different regions, one behind the other in transport direction T, are assigned to a respective conveyor belt 718; 726. This is to be distinguished, in particular, from multiple conveyor belts arranged at least partially one behind the other.
The vacuum pressure is transmitted substantially only through those suction openings 723 that are in communication with the respective vacuum pressure chamber 719. In contrast to one large vacuum pressure chamber 719, multiple small vacuum pressure chambers 719 can therefore act individually, and in particular can be individually sealed off at least partially from an environment. This sealing is accomplished both by conveyor belt 718; 726 itself and by those components of sheets 02 that cover corresponding suction openings 723. If an insufficient proportion of suction openings 723 is covered, the vacuum pressure will be reduced by inflowing ambient air. This could result in the sheets 02 being inadequately held. This risk exists in the case of small sheets 02 and/or when there are large distances between sheets 02 and/or a first sheet 02 and/or a last sheet 02. Subdividing the chamber into a plurality of vacuum pressure chambers 719 along the conveying section ensures that the vacuum pressure cannot decrease significantly in all areas at the same time. Furthermore, providing a plurality of vacuum pressure chambers 719 with a conveyor belt 718; 716 of the same length allows for smaller vacuum pressure chambers 719. As a result, each suction opening 723 makes up a larger proportion of the total number of suction openings 723 assigned to the respective vacuum pressure chamber 719. Thus, a relatively small number of sealed suction openings 723 is sufficient to keep the vacuum pressure in the respective vacuum pressure chamber 719 at a usable level. This relatively small number can also be achieved with small sheets 02 and/or with large distances between sheets 02 and/or with a first sheet 02 and/or a last sheet 02.
Furthermore, it is not relevant whether the vacuum pressure in a vacuum pressure chamber 719 drops too low, as long as a sheet 02 that is partially in the zone of influence of said chamber is still held by the vacuum pressure of another vacuum pressure chamber 719. This also is achieved by the relatively large number of relatively small vacuum pressure chambers 719. This effect can also be purposefully used to supply a vacuum pressure only in the particular relevant vacuum pressure chambers 719 and to purposefully separate insufficiently covered vacuum pressure chambers 719, at least intermittently, from a corresponding vacuum pressure source. Overall, the suctioning action of suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 may vary along the transport direction T. This enables a savings in terms of pumping power and thus of energy.
Preferably, vacuum pressure can be applied to the individual vacuum pressure chambers 719 individually. In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is therefore preferably characterized in that at least a first of these at least two vacuum pressure chambers 719 arranged one behind the other is and/or can be connected to at least one first vacuum pressure source 733 via at least one, in particular first suction line 721. In addition, at least one other, in particular second of these at least two vacuum pressure chambers 719 arranged one behind the other is preferably arranged such that it is and/or can be connected via at least one suction line 721, in particular another and/or a second suction line 721, to at least or precisely one other, in particular second vacuum pressure source 733. More preferably, this at least one other of these at least two vacuum pressure chambers 719 arranged one behind the other is arranged such that it is and/or can be connected via the at least one suction line 721 exclusively to the at least one other, in particular second vacuum pressure source 733. The designation of these components as the first or second vacuum pressure chamber 719, the first or second suction line, or the first or second vacuum pressure source 733, etc. is used here merely to distinguish these components from one another and does not in any way relate to the order or arrangement of these components.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is therefore preferably characterized in that at least a first of these at least two vacuum pressure chambers 719 arranged one behind the other is arranged such that it is and/or can be connected to at least one first vacuum pressure source 733 via at least one, in particular first suction line 721 and at least one first controllable and/or regulable valve 737. In that case, it is not necessary to deactivate or fully deactivate vacuum pressure source 733 in order to deactivate a corresponding vacuum pressure chamber 719. Instead, this can be accomplished merely by appropriate actuation of the at least one valve 737. In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least a second of these at least two vacuum pressure chambers 719 arranged one behind the other is arranged such that it is and/or can be connected via at least one, in particular second suction line 721 and at least one second controllable and/or regulable valve 737 to the at least one first vacuum pressure source 733. In that case, one vacuum pressure source 733 can be used for multiple vacuum pressure chambers 719, enabling equipment expenditures to be minimized. In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one other and/or second of these at least two vacuum pressure chambers 719 arranged one behind the other is arranged such that it is and/or can be connected via at least one other and/or second suction line 721 and at least one other and/or second controllable and/or regulable valve 737 to at least one other and/or second vacuum pressure source 733.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one coating position 409; 609; 809 of at least one coating unit 400; 600; 800 of the sheet-fed printing press 01 is arranged along the conveying section of the at least one conveyor belt 718; 726. This enables particularly high print quality, because a particularly secure positioning of sheets 02 can be achieved, even with small sheets 02, and/or large distances between sheets 02, and/or with a first sheet 02 and/or a last sheet 02. More preferably, at least two, even more preferably at least three, and more preferably still at least four coating positions 409; 609; 809 of at least one coating unit 400; 600; 800 of sheet-fed printing press 01 are arranged along the conveying section of the at least one conveyor belt 718; 726. This enables printing to be optimized in terms of register and/or registration and/or color-to-color register. At least one drying system 500 and/or at least one drying device 506 of sheet-fed printing press 01 is arranged along the conveying section of the at least one conveyor belt 718; 726, for example.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least two, preferably at least three, more preferably at least five, and even more preferably at least seven vacuum pressure chambers 719 that are and/or can be separated from one another with respect to the transverse direction A are arranged side by side, each having at least one suction inlet 722, each suction inlet being arranged at least partially covered by at least one conveyor belt 718; 726 of the suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. These are a plurality of conveyor belts 781; 726, for example, or preferably one common conveyor belt 718; 726. The sheet-fed printing press 01 is preferably characterized in that at least one of these at least two vacuum pressure chambers 719 arranged side by side is arranged such that it is and/or can be connected via at least one suction line 721 to at least one vacuum pressure source 733, and at least one other of these at least two vacuum pressure chambers 719 arranged side by side is arranged such that it is and/or can be connected via at least one other suction line 721 in particular exclusively to another vacuum pressure source 733.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least a first of these at least two vacuum pressure chambers 719 arranged side by side is arranged such that it is and/or can be connected to at least one vacuum pressure source 733 via at least one suction line 721 and at least one controllable and/or regulable valve 737.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one other of these at least two vacuum pressure chambers 719 arranged side by side is arranged such that it is and/or can be connected via at least one suction line 721 and at least one other controllable and/or regulable valve 737 to said at least one vacuum pressure source 733. Alternatively and/or additionally, sheet-fed printing press 01 is preferably characterized in that at least one other of these at least two vacuum pressure chambers 719 arranged side by side is arranged such that it is and/or can be connected to at least one other vacuum pressure source 733 via at least one suction line 721 and at least one other controllable and/or regulable valve 737.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least two, more preferably at least three, even more preferably at least five, and more preferably still at least seven vacuum pressure chambers 719 that are and/or can be separated from one another with respect to the transverse direction A are arranged side by side, with the relative positioning of pairs of said chambers with respect to the transport direction T partially overlapping and partially intersecting. Vacuum pressure chambers 719 arranged in this way are also referred to as vacuum pressure chambers 719 arranged offset from one another in the transport direction T. Vacuum pressure chambers 719 that are offset from one another in the transport direction T allow sheets 02 to be held even more effectively relative to conveyor belt 718; 726. In particular, a sheet 02 entering the exposure zone of a subsequent vacuum pressure chamber 719 or leaving the exposure zone of a previous vacuum pressure chamber 719 can remain simultaneously in the exposure zone of another vacuum pressure chamber 719. This ensures that at least one vacuum pressure chamber 719 is always sealed sufficiently to maintain a vacuum pressure that will hold the sheet 02 on the conveyor belt 02. Preferably, sheet-fed printing press 01 is additionally characterized in that at least one of these at least two vacuum pressure chambers 719 arranged offset from one another in transport direction T is arranged such that it is and/or can be connected via at least one suction line 721 to at least one vacuum pressure source 733, and at least one other of these at least two vacuum pressure chambers 719 arranged offset from one another in transport direction T is arranged such that it is and/or can be connected via at least one other suction line 721 in particular exclusively to another vacuum pressure source 733.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least a first of these at least two vacuum pressure chambers 719 arranged offset from one another in the transport direction T is arranged such that it is and/or can be connected to at least one vacuum pressure source 733 via at least one suction line 721 and at least one controllable and/or regulable valve 737. In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one other of these at least two vacuum pressure chambers 719 arranged offset from one another in the transport direction T is arranged such that it is and/or can be connected via at least one suction line 721 and at least one other controllable and/or regulable valve 737 to said at least one vacuum pressure source 733. In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one other of these at least two vacuum pressure chambers 719 arranged offset from one another in the transport direction T is arranged such that it is and/or can be connected via at least one suction line 721 and at least one other controllable and/or regulable valve 737 in particular exclusively to another vacuum pressure source 733.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one valve 737 assigned to a vacuum pressure chamber 719 or a suction line 721 is connected to a machine controller of the sheet processing machine 01 configured in particular as a sheet-fed printing press 01, said machine controller also having access to data relating to the position of at least one sheet 02 and/or to data relating to the rotational position of at least one drive involved in the transport of the at least one sheet 02. In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one vacuum pressure source 733 associated with a vacuum pressure chamber 719 or a suction line 721 is connected to a machine controller of the sheet processing machine 01 configured in particular as a sheet-fed printing press 01, said machine controller also having access to data relating to the position of at least one sheet 02 and/or to data relating to the rotational position of at least one drive involved in the transport of the at least one sheet 02. By accessing these data, it is possible to vacuum pressurize only those vacuum pressure chambers 719 that are covered sufficiently, or soon will be, in order to actually hold one or more sheets 02. The area of activated vacuum pressure chambers 719, i.e. vacuum-pressurized vacuum chambers, can then be moved along with respective sheets 02 and/or can at least partially precede them and/or follow after them a short distance, for example for safety reasons. This allows suctioning power and thus energy to be used only in metered amounts.
Preferred, therefore, is a method for operating a sheet processing machine 01, in particular a sheet-fed printing press 01, in which at least one sheet 02 is transported by means of a suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 configured as a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011, which has at least one, in particular flexible conveyor belt 718; 726, which moves with at least one conveying section of its circulation path parallel to the transport direction T along a section of the transport path provided for sheets 02, in particular over a transport length. Preferably at least two, more preferably at least three, even more preferably at least five, and more preferably still at least ten vacuum pressure chambers 719, which in particular are and/or can be separated from one another with respect to the transport direction T and each of which has at least one suction inlet 722, are arranged one behind the other along the transport path provided for sheets 02. Preferably, the conveying section of the circulation path of the at least one conveyor belt 718; 726 at least partially covers at least one suction inlet 722 of multiple and more preferably all of these vacuum pressure chambers 719 arranged one behind the other. The method is preferably characterized in particular by the fact that the respective vacuum pressure of each of the at least two vacuum pressure chambers 719 arranged one behind the other is influenced individually and in a temporally varied manner based at least upon data that characterize the position of the at least one sheet 02 along the conveying section, in particular along the conveying section of the circulation path of the at least one conveyor belt 718; 726.
Preferably, the method is characterized in that the at least one sheet 02 is pulled by vacuum pressure against a conveying surface of a conveyor belt 718; 726 of the suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011, said conveyor belt being flexible, in particular, and provided with suction openings 723. The vacuum pressure is preferably determined by the difference between an ambient pressure and a pressure within a respective vacuum pressure chamber 719, the suction inlet 722 of which is covered at least partially by conveyor belt 718; 726. Preferably, the method is characterized in that the at least one sheet 02 is coated in at least one coating unit 400; 600; 800 of the sheet-fed printing press 01 while being transported by means of said suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 configured as a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011. More preferably, the method is characterized in that the at least one sheet 02 is printed in at least one printing unit 600 of the sheet-fed printing press 01 while being transported by means of said suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 configured as a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011.
As described, processing machine 01, which is configured in particular as a sheet-fed printing press 01, preferably comprises the at least one conveyor belt 718; 726, which further preferably extends with at least one conveying section of its circulation path parallel to the transport direction T along a section of the transport path provided for sheets 02. Preferably, precisely one conveyor belt 718; 726 is arranged with respect to the transverse direction A. As viewed in the transport direction T, multiple conveyor belts may be arranged one behind the other and may form different regions of the transport path provided for sheets 02. The at least one conveyor belt 718; 726 is preferably, although not necessarily, configured as a conveyor belt 718; 726 of a suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 of the sheet-fed printing press 01, configured as a suction belt 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011, in particular with said at least one suction transport means 111; 117; 119; 136; 211; 311; 411; 417; 511; 561; 611; 617; 711; 811; 817; 911; 1011 comprising the at least one conveyor belt 718; 726. As described, the at least one conveyor belt 718; 726 preferably has a multiplicity of suction openings 723. As described, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one coating position 409; 609; 809 of at least one coating unit 400; 600; 800 of the sheet-fed printing press 01 is arranged along the conveying section of the at least one conveyor belt 718; 726. More preferably, at least two, even more preferably at least three, and more preferably still at least four coating positions 409; 609; 809 of at least one coating unit 400; 600; 800 of sheet-fed printing press 01 are arranged along the conveying section of the at least one conveyor belt 718; 726. At least one drying system 500 and/or at least one drying device 506 of sheet-fed printing press 01 is arranged along the conveying section of the at least one conveyor belt 718; 726, for example.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one belt alignment means 738 of the at least one conveyor belt 718; 726 is arranged in contact with the at least one conveyor belt 718; 726, and more preferably in that the position of the at least one conveyor belt 718; 7126 with respect to the transverse direction A can be adjusted by adjusting the position of the at least one belt alignment means 738 relative to at least one, in particular stationary frame 427; 431; 508; 627; 631; 827; 831; 744 of sheet-fed printing press 01. This enables a gradual drifting, for example, of the at least one conveyor belt 718; 726 with respect to the transverse direction A to be compensated for at least partially and preferably completely, in particular while said at least conveyor belt 718; 726 is moving for the purpose of transporting sheets 02.
The at least one belt alignment means 738 is preferably configured as at least one belt alignment roller 738, more preferably as at least one belt alignment roller 738 whose rotational axis 742 is variable in terms of its orientation. This alters, in particular, the angle between the axis of rotation 742 of said belt alignment roller 738 and the axial direction A, in particular with respect to the magnitude and/or the position in space of said angle. For example, the at least one belt alignment means 738 is pivotable about an alignment axis, the direction of which has at least one component oriented orthogonally to the transverse direction A. The operating principle of belt alignment means 738 is demonstrated particularly clearly by such a belt alignment roller 738, for example. When belt alignment means 738 is placed in a skewed position, various parts of conveyor belt 718; 726 must travel different distances, depending upon their position relative to the transverse direction A, for the at least one conveyor belt 728 to complete a full revolution. As a result, the at least one conveyor belt 738 is subjected to force with respect to the transverse direction A and is moved accordingly with respect to the transverse direction A while it is executing its circulating movement. This controlled movement is preferably generated only to compensate for unwanted movements with respect to the transverse direction A that have occurred previously and/or otherwise.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one belt alignment means 738 has at least one radial bearing 739, the rotational axis 742 of which is displaceable, at least with respect to a compensation direction W, at least relative to at least one, in particular stationary frame 427; 431; 508; 627; 631; 827; 831; 744 of sheet-fed printing press 01. Preferably, the at least one radial bearing 739 is linearly displaceable at least in and/or opposite the compensation direction W. At least one such radial bearing 739 is at least one radial bearing 739 that enables the at least one belt alignment roller 738 to rotate about its rotational axis 742, for example. More preferably, the at least one belt alignment means 738 has at least two radial bearings 739, arranged spaced apart in the transverse direction A, the rotational axes 742 of which are arranged displaceably, at least with respect to a compensation direction W, at least relative to one another and/or independently of one another and/or relative to at least one, in particular stationary frame 427; 431; 508; 627; 631; 827; 831; 744 of sheet-fed printing press 01. This occurs, for example, by an uneven displacement of radial bearings 739 of belt alignment roller 738. For example, the at least two radial bearings 739 are linearly displaceable at least in and/or opposite the adjustment direction W. It is also possible, however, for at least two belt alignment means 738 to be provided, for example, which are configured, for example, as rollers and are arranged offset or side by side with respect to the transverse direction A, and which are movable independently of one another with respect to the adjustment direction W. Preferred, however, is the case in which precisely one belt alignment means 738, in particular configured as belt alignment roller 738, is provided and the at least two radial bearings 739 are both assigned to this same belt alignment means 738.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that a reference plane is a plane having a normal vector oriented parallel to the transverse direction A, and an adjustment tangent 743 is a tangent 743 to a contacting segment of a line of intersection of the at least one conveyor belt 718; 726 with the reference plane, and the contacting segment is a segment in which contact exists between the at least one conveyor belt 718; 726 and the at least one belt alignment means 738, and the adjustment direction W is oriented parallel to adjustment tangent 743. In that case, the position with respect to the transverse direction A of the at least one conveyor belt 718; 726 can be influenced particularly precisely, in particular without unduly impacting the tension of the at least one conveyor belt 718; 726. More preferably, adjustment direction W runs parallel to a bisector between an approaching direction, in which components of the at least one conveyor belt 718; 726 are moving when they reach the at least one belt alignment means 738 and/or in which an approaching part of the at least one conveyor belt 718; 726 extends, and a departing direction, in which components of the at least one conveyor belt 718; 726 are moving when they leave the at least one belt alignment means 738 and/or in which a departing part of the at least one conveyor belt 718; 726 extends. A deflection angle is preferably the angle by which conveyor belt 718; 726 is deflected between a first and a last contact with the at least one belt alignment means 738. Preferably, the deflection angle is a maximum of 180°, more preferably a maximum of 120°, even more preferably a maximum of 90°, and more preferably still a maximum of 60°.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one belt alignment means 738 has at least one alignment drive 741. This enables the position of the at least one conveyor belt 718; 726 with respect to the transverse direction A to be influenced in a remotely controlled and/or automated fashion. The at least one belt alignment means 738 is preferably configured to be controlled and/or regulated by means of a computer system, with said computer system being a higher-level machine controller of the sheet-fed printing press 01, for example, or at least being connected in terms of circuitry to the higher-level machine controller of the sheet-fed printing press 01. Alternatively, said computer system is independent of the higher-level machine controller of the sheet-fed printing press 01. The at least one alignment drive 741 is configured as an electric motor 741 and/or as a pneumatic cylinder 741 and/or as a hydraulic cylinder 741 and/or as a linear drive 741, for example. At least one sensor is arranged to detect the position of the at least one conveyor belt 716; 726 with respect to the transverse direction A, for example. Signals from said at least one sensor can then be made available, for example, to a press operator and/or can be used to regulate and/or control the at least one alignment drive 741.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one belt alignment means 738 is in contact with only the underside of the at least one conveyor belt 718; 726, said underside being a surface of the at least one conveyor belt 718; 726 which is opposite a conveying surface 718 of the at least one conveyor belt 718; 726, which is provided for contact with sheets 02. This ensures that only forces resulting from paths of different lengths act on the conveyor belt, while wear and tear on the lateral edge of the at least one conveyor belt 718; 726 is largely avoided.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one tensioning means 736 for adjusting and/or maintaining in particular a mechanical tension of conveyor belt 718; 726, in particular of suction belt 718; 726, is provided, and in particular is arranged in contact with said conveyor belt 718; 726. As such a tensioning means 736, for example, at least one deflection roller 736 is provided, the axis of rotation of which is displaceably disposed. The at least one tensioning means 736 is preferably displaceable in and/or opposite at least one tensioning direction. All of the components of the at least one tensioning means 736 that are in contact with the at least one conveyor belt 718; 726 are movable together linearly, for example. The at least one tensioning means 736 has at least two bearings, for example, in particular radial bearings, which are arranged so as to be movable parallel to one another orthogonally to the transverse direction A. At least one tensioning drive is provided, for example, by means of which the at least one tensioning means 736 can be displaced. The at least one tensioning drive is configured, for example, as at least electric motor and/or as at least one hydraulic cylinder and/or as at least one pneumatic cylinder and/or as a linear drive.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the sheet-fed printing press 01 has at least one coating unit 400; 600; 800 configured as a non-impact coating unit 400; 600; 800, and the sheet-fed printing press 01 has at least one conveyor belt 718; 726, which extends with at least one conveying section of its circulation path parallel to a transport direction T along a section of a transport path provided for sheets 02, and along the conveying section of the at least one conveyor belt 718; 726, at least one coating position 409; 609; 809 of at least one coating unit 400; 600; 800 of the sheet-fed printing press 01, determined in particular by at least one print head 416; 616; 816, as seen in
The first frame 427; 627; 827 is preferably the frame 427; 627; 827 of the coating unit 400; 600; 800 or coating module 400; 600; 800.

In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one first frame 427; 627; 827, with the exception of at least one installation surface that is different from the at least one first frame 427; 627; 827 and the at least one second frame 431; 508; 631; 831; 744, is arranged in contact with, i.e., connected to, the second frame 431; 508; 631; 831; 744 at most via flexible connections 435, 634, 834, as depicted schematically in
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the second frame 431; 508; 631; 831; 744 has at least two lateral supports 432; 632; 832, in particular spaced apart from one another with respect to the transverse direction A, and in that the at least one conveyor belt 718; 726 is arranged at least partially between the at least two lateral supports 432; 632; 832 of the second frame 431; 508; 631; 831; 744 with respect to the transverse direction A and/or at least one of the at least two lateral supports 432; 632; 832 is arranged connected via at least one cross member 746 of the second frame 431; 508; 631; 831; 744 to at least one other of the at least two lateral supports 432; 632; 832 of the second frame 431; 508; 631; 831; 744.
Such cross members 746 of the second frame 431; 508; 631; 831; 744 serve in particular to stabilize the second frame 431; 508; 631; 831; 744.

Such cross members 433; 633; 833 of the first frame 427; 627; 827 serve in particular to stabilize the first frame 427; 627; 827. They are preferably configured for optimized stability and are therefore arranged in different positional relationships to the at least one conveyor belt 718; 726. For example, at least one such cross member 433; 633; 833 of the first frame 427; 627; 827 is arranged at least partially vertically below at least one section of the at least one conveyor belt 718; 726, configured in particular as a conveying section. Alternatively or additionally, at least one such cross member 433; 633; 833 of the first frame 427; 627; 827 is preferably arranged at least partially vertically below at least one section of the at least one conveyor belt 718; 726, which section is arranged at least partially vertically below a further section of said at least one conveyor belt 718; 726, configured in particular as a conveying section.

In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that a print head assembly 424; 624; 824 connected directly or indirectly to the side walls 428; 628; 828 of the first frame 427; 627; 827 is arranged at least partially vertically above at least one section of the at least one conveyor belt 718; 726, in particular configured as a conveying section.

The boundaries of said opening preferably lie within a spatial area that is delimited by two planes, the normal vectors of which point in the transport direction T and which are arranged spaced no more than 50 cm apart and more preferably no more than 25 cm apart.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one drive M100; M200; M300; M400; M401; M500; M550; M600; M601; M700; M800; M801; M900; M1000 of the conveyor belt 718; 726 is arranged connected at least partially directly or indirectly and rigidly to the second frame 431; 508; 631; 831; 744. Due to the separation of the frames 427; 627; 827; 431; 508; 631; 831; 744, said at least one drive M100; M200; M300; M400; M401; M500; M550; M600; M601; M700; M800; M801; M900; M1000 is then preferably decoupled from the first frame 427; 627; 827 such that movements of said drive M100; M200; M300; M400; M401; M500; M550; M600; M601; M700; M800; M801; M900; M1000 and/or movements of the at least one conveyor belt 718; 726 have no impact or only very little impact on print quality, particularly in the case of a non-impact printing unit 400; 600; 800.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one energy output device 501; 502; 503 of at least one drying system 500 and/or at least one drying device 506 is arranged aligned toward a section of the at least one conveyor belt 718; 726, and in that said at least one energy output device 501; 502; 503 is connected rigidly or via a positioning device 424; 624; 824 to the first frame 427; 627; 827 or to the second frame 431; 508; 631; 831; 744 or to a third frame, which is different from the first frame 427; 627; 827 and the second frame 431; 508; 631; 831; 744.
Preferably, the sheet-fed printing press 01 is alternatively or additionally characterized in that at least one module 100 configured as a substrate supply system 100 is provided upstream of the at least one priming module 400 and/or upstream of the at least one non-impact printing module 600 along the transport path provided for sheets 02. Preferably, sheet-fed printing press 01 is alternatively or additionally characterized in that at least one cleaning system 201 for sheets 02 is located upstream of the at least one priming module 400 and/or upstream of the at least one non-impact printing module 600 along the transport path provided for sheets 02.
In the following, various embodiments and/or possible configurations of the at least one substrate supply system 100 will be described. Here, various combinations of individual configurations are possible. Substrate supply system 100 is preferably configured as separate from other units 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000, provided no contradictions result. Piles 104 are supplied to the substrate supply system 100, manually and/or by means of an automated system, for example, in particular in the form of piles 104 preferably arranged on carrier units 113. Such carrier units 113 are pallets 113, for example. Piles 104 that are or have been supplied as such to the substrate supply system 100 are also referred to as feeder piles 104, for example. The carrier units 113 or pallets 113 preferably have correspondingly aligned grooves, for example for the engagement of pile carriers, in particular for releasing sheets 02 and/or piles 104 from the carrier units 113 or pallets 113.
The at least one substrate supply system 100 preferably serves to singulate sheets 02 of a pile 104 or partial pile 106 and more preferably to feed said sheets, singulated, to one or more units 200; 300; 400; 500; 550; 600; 700; 800; 900 downstream. The at least one substrate supply system 100 has at least one pile turning device 101 or sheet turning device, for example. Pile turning device 101 preferably serves to turn a pile 104 or partial pile 106 comprising at least a plurality of sheets 02, as a complete unit. Turning the sheets 02 is useful, for example, when two opposing main surfaces of the sheets 02 are different from one another and when subsequent processing is to take place on a specific one of these main surfaces. This is the case, regardless of whether the sheets 02 are turned individually or whether the pile 104 is turned as a complete unit, or whether partial piles 106 are turned. This applies, for example, when the sheets 02 have already been processed before being collected to form the pile 104 and/or when the sheets 02 have main surfaces that are distinguished from one another. Such distinguishable main surfaces are formed, for example, during the production of corrugated cardboard sheets 02.
A pile holding area 102 is an area 102, in particular a spatial area 102, in which the pile 104 that will be subdivided for the subsequent processing of its sheets 02 is located, at least temporarily, at least during operation of the processing machine 01. The pile holding area 102 preferably encompasses the entire spatial area provided for location of such a pile 104, in particular regardless of whether the pile 104 takes up less space than is available, for example because its sheets 02 have already been partially singulated or have a format which is smaller than the maximum possible format. This pile 104 is preferably the feeder pile 104. Thus, the pile holding area 102 is preferably the spatial area 102 that is provided, at least during operation of the processing machine 01, for the positioning of at least one pile 104 configured as feeder pile 104, for the subdivision thereof. The at least one pile turning device 101 is located upstream of the pile holding area 102, for example, with respect to a transport path provided for the sheets 02. In that case, pile 104 can be turned as a complete unit, before being supplied for further processing by processing machine 01, and in particular subdivided. Alternatively or additionally, at least one pile turning device 101 is located downstream of the pile holding area 102 with respect to the transport path provided for sheets 02. In that case, pile turning device 101 is preferably configured as a partial pile turning device 101. A partial pile separator 103 is provided, for example, which serves to separate an upper partial pile 106, in particular, from the pile 104 located in the pile holding area 102. A partial pile 103 preferably contains more than one sheet 02. The partial pile separator 103 is configured, for example, as a partial pile pushing system 103 and/or as a partial pile drawing system.
A partial pile 106 containing a plurality of sheets 02 is removed from pile 104 as follows, for example. First, pile 104 is brought to the height at which the topmost sheet 02 of pile 104 is at the removal height. A partial pile pushing system 103 is then moved toward pile 104, in particular in the transport direction T, until it comes into contact with at least one sheet 02 of the pile 104. This at least one sheet 02 is the bottommost sheet 02 of partial pile 106, for example. The partial pile pushing system 103 is then moved even further, thereby moving the at least one sheet 02 that is in contact with it, and preferably any sheets 02 located above it. These moving sheets 02 are thus moved, in particular pushed, together as a partial pile 106 preferably in the transport direction T.
This partial pile 106 is then fed first to the partial pile turning device 101, for example. The partial pile turning device 101 has at least one transport means 107, for example, which is preferably configured as at least one conveyor belt 107, more preferably at least two conveyor belts 107. Transport means 107 is preferably pivotable at least partially about a pivot axis 108, which is more preferably oriented horizontally and/or orthogonally to the intended transport direction T and/or parallel to the transverse direction A. The at least two conveyor belts 107 can be moved toward one another, for example, in particular with respect to the vertical direction V. This allows the partial pile 106 to be held, in particular clamped, between the two conveyor belts 107 and to pivot together with said conveyor belts about pivot axis 108, in particular about essentially 180°. To introduce the partial pile 106 into the partial pile turning device 101 and/or to move the partial pile 106 out of the partial pile turning device 101, at least one of the at least two conveyor belts 107 is preferably activated. Each of these can be operated in two directions, for example, enabling them to initiate the transport of the partial pile 106 independently of the current pivot position of transport means 107.
Regardless of whether or not a pile turning device 101 or a partial pile turning device 101 is provided, substrate supply system 100 preferably comprises at least one singulating system 109 or sheet singulating system 109. Optionally, a plurality of singulating systems 109 may be provided, in particular spaced from one another and/or one behind the other with respect to the transport direction T. In that case, one singulating system 109 is used for the at least partial singulation of sheets 02, for example, and another singulating system is used for a subsequent full singulation of sheets 02. This at least one singulating system 109 or sheet singulating system 109 is located, for example, downstream of the partial pile turning system 101 with respect to the transport path provided for sheets 02. If no partial pile turning system 101 is provided, after partial pile 106 is created, it is preferably fed immediately to singulating system 109 or sheet singulating system 109. More particularly, if no partial pile separator 103 is provided and/or if no partial piles 106 are produced, the singulating system 109 or sheet singulating system 109 preferably acts directly on a respective pile 104. This pile 104 is the feeder pile 104, for example, which is more preferably located in the pile holding area 102. In that case, the at least one singulating system 109 is configured, for example, as a removal system 114.
The at least one singulating system 109 or sheet singulating system 109 preferably at least partially singulates the sheets 02 of the pile 104 or partial pile 106. In at least one embodiment, the at least one singulating system 109 or sheet singulating system 109 singulates the sheets 02 of the pile 104 or partial pile 106 from below, and in at least one other embodiment, it singulates the sheets from above.
In a first embodiment of a sheet singulating system 109, a partial or full singulation of the sheets 02 of pile 104 or of partial pile 106 from below is carried out, for example, by the pile 104 or partial pile 106, which is resting on at least one lower translational element 111, in particular a lower transport means 111, being transported in particular continuously, for example in the transport direction T, and running at least partially up against a barrier 112, which allows only a lower portion of the pile 104 or partial pile 106 to pass, for example, only one sheet 02 or two sheets 02 or a few sheets 02. At least the bottommost sheet 02 in each case is thereby preferably transported further continuously by means of the at least one lower translational element 111, in particular in the transport direction T, while other sheets 02 are initially held back, and only after at least the bottommost sheet 02 has been transported away are the other sheets able to drop downward until they are themselves in a position in which they can pass through below the barrier 112. The height of barrier 112 is preferably adapted to the thickness of the sheets 02 and/or to a desired type of singulation. As a height-adjustable barrier 112, for example, a weir 112 is used, which is preferably configured as a plate 112. If sheets 02 are to be singulated fully, the height below the barrier is preferably greater than the thickness of the sheets 02 but less than twice the thickness of the sheets 02. If an incomplete singulation, for example in the form of a shingled stream of sheets 02, is sufficient, the height below the barrier is preferably correspondingly greater than twice the thickness of the sheets 02 but less than four times the thickness of the sheets 02, for example. The entire pile 104 is thereby singulated or incompletely singulated, i.e. shingled, in particular if no partial pile separator 103 is provided. Preferably, however, pile 104 is subdivided successively by means of the partial pile separator 103 into partial piles 106, which are then transported further in a turned or unturned position, and are then singulated or incompletely singulated, i.e. shingled.
The lower translational element 111 is configured, for example, as a suction transport means 111, in particular as a suction belt 111 and/or suction box belt 111 and/or roller suction system 111. Preferably, however, in this case at least one relatively simple conveyor belt 111 that has no suction system is used as the lower translational element 111. A respective partial pile 106 is preferably fed by the partial pile turning device 101 to the lower translational element 111, and said partial pile is at least partially singulated by means of the barrier 112 and converted to a stream of singulated or shingled sheets 02, arranged on the at least one lower translational element 111. At this point, a precise positioning of the sheets 02 is preferably not yet necessary, since this precise positioning preferably is not generated until later, in a subsequent processing step by means of at least one additional singulating system 109 and/or by means of an infeed system 300. Said at least one infeed system 300 is configured as part of the substrate supply system 100 or as autonomous.
In a second embodiment of a sheet singulating system 109, the sheets 02 of the pile 104 or partial pile 106, more particularly the sheets of a storage pile or infeed pile, are singulated from below, for example, in that the pile 104 or partial pile 106 or the storage pile or infeed pile is stored in a storage device 134, and at least one acceleration means, in particular primary acceleration means 136, is brought into contact with the bottommost sheet 02 of the pile 104 or partial pile 106 or storage pile or infeed pile in each case, at times that are preferably selected in a controlled and/or regulated manner, and/or acts on this bottommost sheet 02 in a controlled and/or regulated manner. In the foregoing and in the following, when singulation from below by means of this sheet singulating system 109 is described, this refers to a storage pile configured as an infeed pile. This is the case regardless of whether another, for example partial singulation from below or from above has already taken place, or whether this infeed pile has been otherwise preprocessed or was introduced as a complete unit directly into storage device 134 when it was first fed into the substrate supply system 100.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that a respective section of the transport path provided for sheets 02, which section is defined by the at least one primary acceleration means 136, has a minimum radius of curvature measuring at least 2 meters and/or having a direction that deviates no more than 30° from at least one horizontal direction and/or from the transport direction T over the entire range of the respective primary acceleration means 136.
The processing machine 01 preferably configured as sheet-fed printing press 01 and in particular the substrate supply system 100 preferably comprises at least one storage device 134 for at least one stored pile of sheets 02. Storage device 134 is preferably positioned downstream of the pile holding area 102 with respect to the transport path provided for sheets 02. Two storage piles are provided, for example, one of which is configured as an infeed pile and one as a buffer pile. Sheets 02 taken from a first pile 104, configured, for example, as feeder pile 104, can preferably be fed, in particular from above, by means of substrate supply system 100 to storage device 134 and in particular to the at least one storage pile. The at least one storage device 134 preferably includes the at least one singulating system 109 that acts from below, which is configured to remove the bottommost sheet 02 individually in each case from a storage pile and in particular from an infeed pile. This bottommost sheet 02 in each case is preferably the bottommost sheet 02 of a storage pile containing a plurality of sheets 02. This at least one singulating system 109 that acts from below is therefore preferably configured as singulating and/or capable of singulating a storage pile and in particular an infeed pile from below.
Storage device 134 preferably has at least one front stop 137, which is preferably configured as a front wall 137 and/or preferably serves as a front lay mark 127. Alternatively or additionally, a separate front lay mark 127 is provided. Front stop 137 preferably prevents any unwanted movement of each sheet 02 in the transport direction T before it has become the bottommost sheet 02 in the infeed pile. Front stop 137 preferably prevents any tilting or other collapse of the at least one storage pile, in particular the infeed pile and/or the buffer pile, located in the storage device 134.
Storage device 134 preferably has at least one lateral stop 139, preferably configured as a lateral wall 139. More preferably, lateral stops 139 are arranged on both sides of storage device 134 with respect to the transverse direction A. Alternatively or additionally, at least one separate side lay mark 128 is provided. The at least one lateral stop preferably prevents any unwanted movement of each sheet 02 in and/or opposite the transverse direction A before it becomes the bottommost sheet 02 in the infeed pile. The at least one side stop 139 preferably prevents any tilting or other collapse of the at least one storage pile, in particular the infeed pile and/or the buffer pile, located in the storage device 134. Storage device 134 preferably has at least one rear stop 141, preferably configured as rear wall 141. The at least one rear stop 141 is located upstream of the at least one storage pile with respect to the transport direction T and preferably prevents any unwanted movement of each sheet 02 opposite the transport direction T before it becomes the bottommost sheet 02 in the infeed pile. Rear stop 141 preferably prevents any tilting or other collapse of the at least one storage pile, in particular the infeed pile and/or the buffer pile, located in the storage device 134.
Singulating system 109 preferably has at least one acceleration means, in particular primary acceleration means 136, in particular for accelerating the bottommost sheet 02 in each case of the at least one storage pile or infeed pile, more preferably in the transport direction T. The at least one primary acceleration means 136 is preferably located beneath the at least one storage pile, more preferably beneath the at least one infeed pile and even more preferably also further beneath the at least one buffer pile. The at least one primary acceleration means 136 is configured, for example, as at least one transport roller 136 and/or as at least one conveyor belt 136 and/or as at least one suction transport means 136, in particular suction belt 136 and/or suction box belt 136 and/or roller suction system 136 and/or suction gripper 136 and/or suction roller 136, and/or preferably has at least one conveyor belt 718; 726. The description relating to the suction transport means in the foregoing and in the following preferably applies accordingly. A plurality of primary acceleration means 136 are provided, for example, in particular in the form of a plurality of transport rollers 136 and/or a plurality of conveyor belts 136; 718, 726 and/or a plurality of suction transport means 136. For example, a plurality of primary acceleration means 136 are arranged one behind the other with respect to the transport direction T. Alternatively or additionally, the at least one primary acceleration means 136 has at least two, more preferably at least three, even more preferably at least five, and more preferably still at least seven transport surfaces 718, in particular conveyor belts 718; 726, which are separated from one another with respect to the transverse direction A by gaps. The at least two, preferably at least three, even more preferably at least five, and more preferably still at least seven transport surfaces 718 and/or conveyor belts 718; 726 of the at least one primary acceleration means 136, which are separated from one another with respect to the transverse direction A by gaps, can preferably be driven by means of a common primary drive M101.
At least one spacer 144; 144.1; 144.2 is preferably provided. The at least one spacer 144; 144.1; 144.2 preferably serves to keep the at least one primary acceleration means 136 at a distance from any sheet 02, at least temporarily and/or in a controlled and/or regulated manner. For example, one sheet 02 or multiple sheets 02 or a pile of sheets 02 lie at least intermittently on the at least one spacer 144; 144.1; 144.2. The at least one primary acceleration means 136 and the at least one spacer 144; 144.1; 144.2 are preferably arranged movably relative to one another, at least with respect to the vertical direction V, in particular by vertical mobility of the at least one spacer 144; 144.1; 144.2 and/or by vertical mobility of the at least one primary acceleration means 136. The at least one spacer 144; 144.1; 144.2 is configured, for example, as at least one bearing surface, provided with recesses, for sheets 02, and/or the primary acceleration means 136 protrude at least partially and/or at least intermittently upward through and out of the recesses. The total of the respective bearing surfaces may be smaller than the total surface area of the recesses.
In a holding position, the respective bottommost sheet 02 of the infeed pile rests on the spacer 144; 144.1; 144.2 without touching the primary acceleration means 136. When the at least one spacer 144; 144.1; 144.2 is then lowered and/or the at least one primary acceleration means 136 is raised, the respective bottommost sheet 02 of the infeed pile comes into contact with the corresponding at least one primary acceleration means 136. By the appropriate actuation of the at least one primary acceleration means 136, said sheet 02 is moved forward in the transport direction T. At the moment when the at least one primary acceleration means 136 comes into contact with the bottommost sheet 02 of the infeed pile, said acceleration means is preferably stationary, and is then accelerated, thereby accelerating said sheet 02 at the same time. Preferably, the at least one primary acceleration means 136 is itself accelerated at least temporarily while a respective sheet 02 is being accelerated, in particular from a stationary state to the first speed v1. The at least one primary acceleration means 136 is preferably decelerated and in particular is halted once it has moved out of contact with said sheet 02.
Alternatively, in particular with appropriate actuation of the primary acceleration means 136, the at least one spacer 144; 144.1; 144.2 can be omitted. Preferably, only the at least one primary acceleration means 136 which is in contact with what is currently the bottommost sheet 02 of the infeed pile is actuated. Primary acceleration means 136 that are not in contact with any sheet 02 or are already in contact with the next sheet 02 are then preferably first halted. Primary acceleration means 136 that are already out of contact with what is currently the bottommost sheet 02 of the infeed pile are preferably first halted and/or kept or moved out of contact with the next sheet 02. In the case of a suction transport means 136, for example, sections of a suction device can be switched off selectively.
The at least one primary acceleration means 136, alone or in cooperation with at least one additional, in particular secondary, acceleration means 119, preferably serves to accelerate precisely one sheet 02 at a time that has preferably already been aligned with respect to the transport direction T and/or the transverse direction A. This acceleration is carried out, for example, from a temporary stationary state and/or to a processing speed and/or coating speed and/or printing speed at which at least one sheet 02 is transported, at this and/or at a later time, through at least one additional unit 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000 or module 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000, where it is processed, more particularly is transported through the at least one non-impact coating unit 400; 600; 800, where it is preferably coated. Optionally, this acceleration may be carried out in combination with additional, in particular secondary acceleration means 119. By means of the at least one primary acceleration means 136 and/or the at least one secondary acceleration means 119, a respective sheet 02 can thus be accelerated from a stationary state and/or from a first speed v1 to a second speed v2, while at the same time at least one other sheet 02 is being transported at a processing speed and/or coating speed and/or printing speed through the at least one additional unit 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000 or module 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000, in particular non-impact coating unit 400; 600; 800, and more preferably processed there, in particular coated and/or printed.
The first speed v1 is preferably a different speed from the processing speed and/or coating speed and/or printing speed. The second speed v2 is preferably equal to the processing speed and/or coating speed and/or printing speed. At least one outgoing transport means 119 of the substrate supply system 100 is preferably located downstream of the at least one primary acceleration means 136 with respect to the transport direction T. Said transport means is configured, for example, as at least one transport cylinder 119 or at least one pair of transport cylinders 119 or as at least one suction transport means 119. This at least one outgoing transport means 119 is likewise an acceleration means 119, for example, in particular the at least one secondary acceleration means 119. The at least one secondary acceleration means 119 is preferably configured as a suction transport means 119 and/or the at least one secondary acceleration means 119 preferably has at least one conveyor belt 718; 726. For example, the at least one secondary acceleration means 119 has at least two, more preferably at least three, more preferably at least five, and even more preferably at least seven transport surfaces 718, in particular conveyor belts 718; 726, which are separated from one another with respect to the transverse direction A by gaps. The at least two, preferably at least three, even more preferably at least five, and more preferably still at least seven transport surfaces 718 and/or conveyor belts 718; 726 of the at least one secondary acceleration means 119, which are separated from one another with respect to the transverse direction A by gaps, can preferably be driven by means of a common secondary drive M102.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that a respective section of the transport path provided for sheets 02, which section is defined by the at least one secondary acceleration means 119, has a minimum radius of curvature measuring at least 2 meters and/or having a direction that deviates no more than 30° from at least one horizontal direction and/or from the transport direction T over the entire range of the respective primary acceleration means 119.
The at least one front stop 137 and/or the at least one front lay mark 127 preferably serves to align the sheets 02 of the infeed pile. For example, the at least one front stop 137 and/or the at least one front lay mark 127 is at least intermittently arranged such that it acts on at least the second sheet 02 from the bottom of the infeed pile and/or is out of contact with the bottommost sheet 02 of the infeed pile in each case. Alignment occurs, for example, when the sheet 02 lying on top of the bottommost sheet 02 is pressed against the at least one front stop 137 and/or the at least one front lay mark 127 by the transport of the bottommost sheet 02 and is thereby aligned before said top sheet itself comes into contact with the at least one, in particular primary acceleration means 136, which at that time is further preferably stationary. The surface of the at least one front stop 137 that is provided for contact with sheet 02 is preferably oriented opposite the transport direction T. At least one pressing element and/or deflecting element is provided, for example, which causes the sheet 02 to butt up against front stop 137 and/or front lay mark 127 and which is configured, for example, as at least one brush. In this way, the sheets 02 always come into contact with the at least one acceleration means 136 in a defined position and can be further transported via said acceleration means in a precisely known position.
The position of the at least one front stop 137 in terms of the vertical direction V is preferably adjustable. The height of the at least one front stop 137 and/or the at least one front lay mark 127 is preferably adjustable, allowing it to be adapted to different thicknesses of sheets 02. During a processing operation of sheet processing machine 02, a passage gap delimited at least upwardly by the at least one front stop 137 is preferably larger than the thickness of a respective one of the sheets 02 to be processed and smaller than twice the thickness of a respective one of the sheets 02 to be processed. Alternatively or additionally, the at least one front stop 137 and/or the at least one front lay mark 127 is disposed such that it can be moved, for example, in particular pivoted, so as to open up the transport path provided downstream for the bottommost sheet 02 only when said sheet has been aligned by contact with said at least one front stop 137 and/or said at least one front lay mark 127. Preferably, sheet feeder unit 100 has at least one front stop 137 which is arranged along the transport path provided for sheets 02, between the at least one primary acceleration means 136 and the at least one secondary acceleration means 119. If substrate supply system 100 has at least one front lay mark 127 and/or at least one front stop 137, for example, the infeed system 300 is preferably a component of the substrate supply system 100 and more preferably is a component of the singulating system 109.
Adjustment to different widths of sheets 02 to be processed is preferably possible. In this context, the width of a sheet 02 is understood in particular as its dimension in the transverse direction A. The sheet processing machine 01 preferably configured as a sheet-fed printing press 01 is characterized, for example, in that the sheet feeder module 100 has at least one suction transport means 119; 136; 311, in particular for transporting sheets 02 in a transport direction T and/or configured as a suction belt 119; 136; 311, and said at least one suction belt 119; 136; 311 has at least three conveyor belts 119; 136; 718; 726 arranged side by side and spaced from one another in a transverse direction A, and more preferably, at least one displacement means 158; 159 is provided, by means of which at least one of the at least three conveyor belts 119; 136; 718; 726 can be displaced, in particular as a whole and/or linearly and/or without pivoting movement, sideways, in and/or opposite the transverse direction A, which is horizontal and/or orthogonal, in particular, to the transport direction T. Preferably, the at least one primary acceleration means 136 is configured as a suction belt 119; 136; 311 having these characteristics and/or the at least one secondary acceleration means 119 is configured as a suction belt 119; 136; 311 having these characteristics. The at least one lateral stop and/or the at least one side lay mark 128 is preferably provided in that the lateral stops 139, in particular lateral walls 139, are movable with respect to the transverse direction A, and can be arranged adjusted, in particular, to the width of sheets 02. This enables the sheets 02 to slide along side walls 139 during the preferably downward-directed movement of said sheets, induced by the removal of the respectively bottommost sheet 02, and enables said sheets to be moved into and/or held in an aligned position. Regions of acceleration means 119; 136 and/or conveyor belts 119; 136; 718; 726 that lie beyond the width of a sheet 02 currently being processed can be covered by means of at least one protective cover. This at least one protective cover is configured, for example, as at least one telescoping plate. Alternatively, at least one active movement of sheets 02, in particular actuated by a drive, against at least one lateral stop 139 is provided, for example, in the case of a sheet 02 which is substantially stationary and/or is stationary at least with respect to the transport direction T. Lateral alignment is carried out, for example, before and/or during and/or after the acceleration of sheets 02 with respect to the transport direction T. Alternatively or in addition to mechanical front stops 137 and/or side stops 139, appropriate position sensors are provided, which move and/or halt the movement of a respective sheet 02 in the respective direction using a correspondingly precise drive and/or move beneath said sheet during its transport movement for the purpose of aligning said sheet.
In an alternative or additional refinement, the processing machine 01 preferably configured as sheet-fed printing press 01 is preferably configured in that the sheet processing machine 01 comprises at least two units 100; 600 configured as modules 100; 600, and in that further preferably, the at least two modules 100; 600 each have at least one uniquely dedicated drive M100; M101; M102; M103; M600; M601, and in that at least one of the at least two modules 100 is a sheet feeder module 100 configured as a substrate supply system 100, and in that the substrate supply system 100 has at least one primary acceleration means 136 having a primary drive M101; M103 of the substrate supply system 100 and has at least one secondary acceleration means 119 having a secondary drive M102 of the substrate supply system 100, said secondary acceleration means being located downstream of the at least one primary acceleration means 136 in the transport direction T along a transport path provided for the transport of sheets 02, and in that at least one additional drive M200; M300; M400; M500; M550; M600; M700; M800; M900; M1000, which is different from the primary drive M101; M103 of substrate supply system 100 and from the secondary drive M102 of substrate supply system 100, is associated with at least one additional module 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000, for the transport of sheets 02. More preferably, primary drive M101; M103 and secondary drive M102 and the at least one additional drive M200; M300; M400; M500; M550; M600; M700; M800; M900; M1000 are each configured as a position-controlled electric motor M100; M200; M300; M400; M500; M550; M600; M700; M800; M900; M1000. Further preferably, a drive controller of the primary drive M101; M103 is different from a drive controller of secondary drive M102, and a drive controller of the at least one additional drive M600 is different from the drive controller of primary drive M101; M103 and different from the drive controller of secondary drive M102. In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the drive controller of primary drive M101; M103 and the drive controller of secondary drive M102 are connected by circuitry to a machine controller of sheet processing machine 01, and more preferably in that the drive controller of primary drive M101; M103 and the drive controller of secondary drive M102 and the drive controller of the at least one additional drive M600 are connected by circuitry to the machine controller of sheet processing machine 01.
The at least one additional module 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000 is preferably configured as a coating module 400; 600; 800 and/or printing module 600 and/or as a non-impact coating module 400; 600; 800 and/or non-impact printing module 600, and/or preferably has at least one print head 416; 616; 816 and/or inkjet print head 416; 616; 816.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that at least one sheet sensor 164 of substrate supply system 100 is arranged aligned toward the provided transport path for the purpose of detecting a respective leading edge and/or a respective trailing edge of respective sheets 02. In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one sheet sensor 164 is located downstream of the at least one primary acceleration means 136 and/or downstream of the at least one front stop 137 and/or upstream of the at least one secondary acceleration means 119 with respect to the transport direction T. Alternatively or additionally, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one sheet sensor 164 is located in the region of the at least one secondary acceleration means 119 and/or downstream of the at least one secondary acceleration means 119 with respect to the transport direction T.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one secondary acceleration means 119 is configured as a suction transport means 119 and is located exclusively below the transport path provided for sheets 02, and/or in that the at least one primary acceleration means 136 is configured as a suction transport means 136 and is arranged exclusively below the transport path provided for sheets 02, and/or in that the at least one primary acceleration means 136 is located below a storage area 134 provided for storing a pile of sheets 02, and/or in that the at least one primary acceleration means 136 is movable, in particular as a complete unit, with respect to a vertical direction V by means of at least one vertical drive.
Adjustment to different lengths of sheets 02 to be processed is preferably possible. In this context, the length of a sheet 02 is understood, in particular, as its dimension in the transport direction T and/or its horizontal dimension oriented orthogonally to the transverse direction A. Adjustment is preferably accomplished in that the at least one front stop 137 and/or more preferably the at least one rear stop 141 is and/or can be moved with respect to the transport direction T and is and/or can be positioned adjusted in particular to the length of the sheets 02. Changing the position of the rear stop 141 changes the position of the starting edge of storage device 134 with respect to the transport direction T, for example. To compensate for this, in particular, a transport means 111 located upstream of storage device 134 with respect to the transport direction T is preferably configured as variable in terms of its effective length with respect to the transport direction T. For this purpose, said transport means 111 has, for example, a first number of transport elements or conveyor belts, the active area of which is invariable. These are configured as conveyor belts, for example. Said transport means 111 preferably additionally has a second number of transport elements, for example, the active area of which is variable. These are configured, for example, as transport elements and/or conveyor belts that are displaceable as a complete unit, at least with respect to the transport direction T. Appropriate displacement of the displaceable transport elements in and/or opposite the transport direction T results in a modified effective length of the totality of transport elements that are invariable in terms of their active area and transport elements that are variable in terms of their active area.
Alternatively or additionally, substrate supply system 100 is characterized in that the substrate supply system 100 has at least one transport means 119 located downstream of the storage device 134 with respect to the transport direction T, which transport means is configured as variable in terms of its effective length with respect to transport direction T.
The at least one buffer pile serves in particular to ensure a continuous supply of sheets 02. Corrugated cardboard sheets 02, in particular, are relatively thick, i.e. have relatively great dimensions in the vertical direction V. This enables piles 104 of corrugated cardboard sheets 02 to be processed very quickly by singulation. For an uninterrupted supply of sheets 02 to processing machine 01, a buffering of sheets 02, which can be processed at least partially while feeder pile 104 is being replaced or renewed, is therefore advantageous. For this purpose, sheets 02 are preferably conveyed from the feeder pile 104 to the buffer pile at least partially at a greater speed than the speed at which they are conveyed later and/or at a greater speed than the speed at which other sheets 02 are conveyed and/or coated at the same time in processing machine 01 and in particular in the coating unit 400; 600; 800 thereof. During the renewal of feeder pile 104, the buffer pile decreases and is refilled again afterward, while sheets 02 are removed from said buffer pile, in particular from the bottom, and fed to the infeed pile, preferably at a uniform rate, in particular by means of the at least one metering element. The at least one transport means 111 located upstream of the storage device 134 and in particular downstream of feeder pile 104 and/or downstream of a main pile carrier provided for said feeder pile 104 with respect to transport direction T can preferably be operated at a respective time at a speed that is different from, and more preferably is at least intermittently higher than a coating speed or printing speed at which sheets 02 are transported through the at least one coating unit 400; 600; 800 at said time. In substrate supply system 100, a drive M100 associated with said transport means 111 can preferably be operated independently of a drive M400; M600; M800 associated with coating unit 400; 600; 800.
Sheets 02 are preferably fed to storage device 134 from above. More preferably, these sheets 02 are fed to storage device 134 fully singulated or at least partially singulated. Sheets 02 are preferably fed to storage device 134 by first being removed from a feeder pile 104. For this purpose, sheets 02 are fully or partially singulated.
This singulation of sheets before being fed into storage device 134 is carried out as described, for example, from below, in particular by means of a lower transport means 111, on which the sheets 02, in the form of a pile 104 or preferably a partial pile 106, run at least partially up against barrier 112 and are thereby singulated or partially singulated, i.e. shingled, depending upon the setting of the barrier 112. This results in an overlapped shingling, i.e. a shingling in which a subsequent sheet 02 is arranged partially on top of a sheet 02 preceding it. The sheets 02 are then conveyed by means of transport means 111 until they enter storage device 134 at the end of said transport means. This preferably involves the sheets 02 being dropped into a chute of storage device 134. This chute is formed, for example, by the at least one front stop 137 and/or the at least one rear stop 141 and/or the at least one lateral stop. Preferably, at least one pressure cylinder 146 and/or pressure roller 146 is provided, which presses the sheets 02 against the transport means 111 that is immediately upstream of the chute. This enables the sheets 02 to be fed to the chute in a controlled manner. The cross-sectional area of the chute is preferably downwardly decreasing. This enables the sheets 02 to be aligned, in particular with respect to the transport direction T and/or with respect to the transverse direction A, as the sheets 02 are being dropped. Each dropping sheet 02 then becomes the topmost sheet 02 of the subsequent storage pile in sequence, which is preferably the buffer pile.
An alternative at least partial singulation of the sheets 02 of the pile 104 configured, in particular, as feeder pile 104 or of a partial pile 106 from above is preferably carried out in that with each removal of a sheet 02, the main body of pile 104 remains at least substantially unchanged with respect to the transport direction T and is merely raised continuously or gradually where appropriate. In this case, the main body of pile 104 is preferably made up of all the sheets 02 of the pile 104 that have not yet been removed. Substrate supply system 100 preferably has at least one removal system 114 which acts or is capable of acting from above on sheets 02 of pile 104. The at least one removal system 114 is preferably capable of picking up and further transporting the topmost sheet 02 of pile 104 in each case. The at least one removal system 114 has, for example, at least one handling element 116 preferably configured as a lifting element 116 and/or holding element 116, which is preferably configured as at least one lifting sucker 116 and/or at least one separating sucker 116 and/or at least one transporting sucker 116. The at least one lifting element 116 can preferably be moved with at least one component in particular upward in the vertical direction V, and downward opposite the vertical direction V. At least one blower device, not shown, is preferably provided, in particular upstream of removal system 114 with respect to the transport direction T. Said blower device serves, for example, to facilitate the separation of the topmost sheet 02 from the sheet 02 beneath it. Removal system 114 further preferably has at least one upper translational element 117. The at least one upper translational element 117 preferably serves at least to move the sheets 02 in the intended transport direction T, for example up to a further, in particular outgoing, transport means 119 of the substrate supply system 100 or up to a further unit 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000 or up to a transport means 111 that leads to storage device 134. The further transport means 119 of substrate supply system 100 preferably ensures the further transport of sheets 02, in particular in the transport direction T and/or up to an outlet 121 of substrate supply system 100.
The at least one handling element 116, in particular lifting element 116 and/or holding element 116, is located, for example, on the at least one upper translational element 117 and can be moved together with said translational element, in particular in and opposite the vertical direction V and/or in and opposite the transport direction T. In that case, removal system 114 is configured, for example, as a known sheet separator 114. Such a sheet separator 114 picks up the topmost sheet 02, in particular by suction, then preferably raises it at least slightly and moves it at least also in the intended direction of transport T until it enters an area of influence of another system, which continues the transport of said sheet. Such a sheet separator 114 is characterized, for example, in that its upper translational element 117 executes an oscillating movement and/or moves at least and preferably precisely once per sheet 02 in the transport direction T and then reverses and moves at least and preferably precisely once per sheet 02 opposite the transport direction T.
Alternatively, the at least one upper translational element 117 can be operated and/or moved separately from the at least one handling element 116, in particular lifting element 116 and/or holding element 116. The at least one upper translational element 117 is configured, for example, as transport means 117, in particular as suction transport means 117 and preferably as suction belt 117 and/or suction box belt 117 and/or roller suction system 117, the suction inlets 722 or suction openings 724 of which preferably point at least also or only downward and/or the suction effect of which is preferably directed at least also or only upward. In that case, removal system 114 is characterized by the fact that the upper translational element 117 executes a circulating movement. The at least one lifting element 116 can then preferably be moved far enough upward that a sheet 02 held by it comes into contact with the at least one upper translational element 117 or at least enters into the processing region thereof far enough that when the at least one lifting element 116 is subsequently deactivated, the sheet can be held by the at least one upper translational element 117. For example, the at least one lifting element 116 can be moved upward far enough that each region of the at least one lifting element 116 that is intended as a contact region between the at least one lifting element 116 and the sheet 02 is located as high as or higher than each region of the at least one upper translational element 117 that is intended as a contact region between the at least one upper translational element 117 and the sheet 02. This region intended as a contact region is the transport surface 718 or counterpressure surface 718 of the upper translational element 117, for example.
In one embodiment, the at least one lifting element 116 can be moved upward far enough that a sheet 02 being held by said element enters into contact with the at least one upper translational element 117, in particular with the transport surface 718 or counterpressure surface 718 thereof, and can be transported at least in the transport direction T by the at least one upper translational element 117, while the at least one lifting element 116 at least also ensures that the sheet 02 is drawn against the at least one upper transport element 117. In that case, the at least one lifting element 116, at least in its raised position, acts as part of the at least one upper translational element 117, for example, more preferably without itself being movable in the transport direction T. This is preferably the case, in particular, when the at least one upper translational element 117 is configured as a roller suction system 117. Alternatively, however, this is also the case if the at least one upper translational element 117 is configured as a suction belt 117 and/or as a suction box belt 117.
Depending upon the mode of operation, a stream of fully singulated sheets 02 or a stream of shingled sheets 02 overlapping one another can be produced. This is dependent, for example, upon the ratio of the average transport speed of the sheets 02 in the transport direction T to the frequency with which the sheets 02 are removed from the pile 104.
Independently of additional configurations of the at least one substrate supply system 100, said system preferably comprises at least one outgoing transport means 119, which is further preferably configured as suction transport means 119 and/or as at least one transport roller 119 or at least one pair of transport rollers 119 which together form a transport nip, and/or as at least one pair of conveyor belts 119 which together form a transport nip. The outgoing transport means 119 serves, for example, to discharge sheets 02 from the substrate supply system 100, in particular up to an outlet 121 of the substrate supply system 100. At least one pressure cylinder 122 and/or pressure roller 122 that cooperates in particular with the outgoing transport means 119 is provided, for example.
Regardless of whether singulation is carried out from above and/or from below, substrate supply system 100 preferably has, in particular, at least one drive M100 or motor M100, in particular electric motor M100 or position-controlled electric motor M100, dedicated uniquely to it, which is further preferably positioned such that it drives and/or is capable of driving at least one transport means 111; 117; 119 of the substrate supply system 100. In particular if at least one acceleration means 119; 136 is provided, the substrate supply system 100 preferably comprises at least one first, in particular additional drive M101; M103 or motor M101; M103, in particular electric motor M101; M103 or position-controlled electric motor M101; M103, which is further preferably positioned such that it drives and/or is capable of driving at least one acceleration means 119; 136 of the substrate supply system 100. The substrate supply system 100 preferably has at least one primary acceleration drive M101, which further preferably is configured, in particular, as a position-controlled electric motor M101 and/or which is positioned such that it drives and/or is capable of driving at least one first acceleration means 136. The at least one first, in particular additional drive M101; M103 is also referred to as the primary drive M101; M103 or primary acceleration drive M101; M103 of the substrate supply system 100. Substrate supply system 100 preferably has, for example, at least one second additional drive M102 or motor M102, in particular electric motor M102 or position-controlled electric motor M102, dedicated uniquely to it, which is more preferably positioned such that it drives and/or is capable of driving at least one outgoing transport means 119 and/or at least one transport means 119 or secondary acceleration means 119 of substrate supply system 100 that acts and/or is capable of acting on sheets 02 downstream of the at least one, in particular primary acceleration means 136. Preferably, at least the first additional drive M101; M103 and/or at least the second additional drive M102 can be driven independently of other drives M100; M101; M102; M103 of the substrate supply system.
Substrate supply system 100, which is preferably configured as unit 100 and/or as module 100, is preferably additionally or alternatively characterized in that the section of the transport path provided for sheets 02, defined by the substrate supply system 100, ends at an outlet height of the substrate supply system 100. This section of the transport path provided for sheets 02 and preferably the entire transport path provided for sheets 02 preferably begins with the singulation of sheets 02. The outlet height of substrate supply system 100 preferably deviates no more than 5 cm, more preferably no more than 1 cm, and even more preferably no more than 2 mm from the first standard height.
In an alternative or additional refinement, the processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that it comprises at least one unit 100; 300, which has at least one suction transport means 119; 136; 311, configured as suction belt 119; 136; 311, for transporting sheets 02 in a transport direction T. Alternatively or additionally, said at least one suction belt 119; 136; 311 has at least three conveyor belts 119; 136; 718; 726 arranged side by side and spaced apart with respect to a transverse direction A, with at least one displacement means 158; 159 being provided, by means of which at least one of the at least three conveyor belts 119; 136; 718; 726 can be displaced sideways in and/or opposite the transverse direction A, in particular can be displaced sideways in an adjustable manner and/or relative to at least one in particular stationary frame 162 of said at least one unit 100; 300. Thus, the at least three conveyor belts 119; 136; 718; 726 arranged side by side are preferably not only arranged offset with respect to the transverse direction A, but, proceeding from a respective one of these at least three conveyor belts 119; 136; 718; 726, at least one other of the at least three conveyor belts 119; 136; 718; 726 is arranged in and/or opposite the transport direction A.
The displaceability of at least one conveyor belt 119; 136; 718; 726 enables an adaptation to the width and/or the position of sheets 02 to be processed. If multiple conveyor belts 119; 136; 718; 726 are arranged side by side, various situations arise depending upon the width of the sheets 02 and the position of the conveyor belts 119; 136; 718; 726. Ideally, the ends of the sheets 02 with respect to the transverse direction A each lie on a conveyor belt 119; 136; 718; 726. However, since gaps and particularly suction inlets 722 are arranged in each case between conveyor belts 119; 136; 718; 726 with respect to transverse direction A, for example, various risks exist. For one, an end of a respective sheet 02 with respect to the transverse direction A may lie over a suction inlet 722, for example, and may then be pulled at least partially into the suction inlet 722 by the negative pressure. This might result in a bending of the respective sheet 02, which can in turn lead to problems and/or inaccuracies in the transport and/or further processing of sheets 02. Furthermore, there is a risk that a sheet 02, the end of which with respect to the transverse direction A rests on a conveyor belt 119; 136; 718; 726 by only a very short distance, for example two millimeters or less, might be pulled by that end into a suction inlet 722, and might thereby come into contact laterally with the conveyor belt 119; 136; 718; 726 and might be displaced with respect to the transverse direction A as a result.
The displaceability of at least one conveyor belt 119; 136; 718; 726 enables such situations to be avoided or at least mitigated, for example by displacing at least one conveyor belt 119; 136; 718; 726 or preferably multiple or more preferably all of the side-by-side conveyor belts 119; 136; 718; 726 with respect to the transverse direction A, thereby creating advantageous conditions in the region of the ends of sheets 02 with respect to the transverse direction A. This enables sheets 02 of different widths to each be handled optimally. In particular, conveyor belts 119; 136; 718; 726 can then be arranged asymmetrically relative to the center of the respective unit 100; 300, at least temporarily, allowing sheets 02 to be transported in a centered position regardless of their width. The position of the at least one conveyor belt 119; 136; 718; 726 is preferably adjusted before the start of a processing operation and, for example, once per processing order, or only when processing sheets 02 whose width differs from the width of sheets 02 processed previously. (In
In an alternative or additional refinement, the sheet processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one unit 100; 300 has at least one lateral stop 139, which in particular is stationary during operation of the sheet processing machine 01, and/or has at least one side lay mark 128, which in particular is stationary during operation of the sheet processing machine 01, for the alignment of sheets 02 with respect to the transverse direction A. Said at least one lateral stop 139 and/or said at least one side lay mark 128 is preferably adjustable in terms of its position with respect to the transverse direction A and/or is preferably used for the alignment of sheets 02 with respect to the transverse direction A. Said lateral stop or said side lay mark is therefore preferably stationary, in particular during operation of sheet processing machine 01. Preferably, the at least one lateral stop 139, which is arranged fixed in position in particular during operation of sheet processing machine 01 and is used for the alignment of sheets 02 with respect to the transverse direction A, is adjustable in terms of its position with respect to the transverse direction A, independently of the position of the at least three conveyor belts 119; 136; 718; 726 with respect to the transverse direction A, and/or the at least one side lay mark 128, which is arranged fixed in position in particular during operation of sheet processing machine 01 and is used for the alignment of sheets 02 with respect to the transverse direction A, is adjustable in terms of its position with respect to the transverse direction A, independently of the position of the at least three conveyor belts 119; 136; 718; 726 with respect to the transverse direction A.

In particular, the at least one lateral stop 139 and/or the at least one side lay mark 128 are preferably arranged such that they are movable and/or adjustable relative to a frame 162 of the at least one unit 100; 300, which is further preferably arranged fixed in place. The at least three side-by-side conveyor belts 119; 136; 718; 726 are preferably arranged at least partially alongside the at least one lateral stop 139 and/or the at least one side lay mark 128 in the transverse direction A.

More preferably, said transport assembly 136; 161; 163; 718; 726 comprises multiple and even more preferably all of the conveyor belts 119; 136; 718; 726 of the at least one suction belt 119; 136; 311 of said unit 100; 300. The at least one displacement means 158 preferably has at least one manual drive 159 and/or at least one electric drive 159 and/or at least one pneumatic drive 159 and/or at least one hydraulic drive 159. As a manual drive 159, at least one handwheel is provided, for example.
In an alternative or additional refinement, the sheet processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least three conveyor belts 119; 136; 718; 726 are arranged in an invariable position relative to one another with respect to the transverse direction A and/or are spaced at a constant distance from one another.

Particularly preferably, all of the components of the respective at least one suction belt 119; 136; 311 of said unit 100; 300 are components of the transport assembly 136; 161; 163; 718; 726 and/or are displaceable jointly with respect to the transverse direction A. As described, transverse direction A is a direction A that extends horizontally and/or is oriented orthogonally to the intended transport direction T of sheets 02 through the at least one unit 100; 300 and preferably through the at least one coating unit 400; 600; 800.
In an alternative or additional refinement, the sheet processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one unit 100; 300 has at least two suction transport means 119; 136; 311 configured as suction belts 119; 136; 311 for transporting sheets 02 in a transport direction T, which are arranged one behind the other with respect to the transport direction T and which are designated as the first suction belt 119; 136; 311 and as the additional suction belt 119; 136; 311, for example.

Processing means 201 is located, for example, within another unit 100; 300; 400; 500; 550; 600; 700; 800; 900; 1000 or module 100; 300; 400; 500; 550; 600; 700; 800; 900; 1000, in particular aligned toward and/or acting and/or capable of acting on the provided transport path. Preferably, however, preprocessing system 200 is configured as an autonomous unit 200 and more preferably as a module 200.

The description relating to suction transport means in the foregoing and in the following preferably applies accordingly. Preprocessing system 200 preferably has at least one drive M200 or motor M200, in particular electric motor M200 or position-controlled electric motor M200, dedicated uniquely to it, which is further preferably positioned such that it drives and/or is capable of driving the at least one transport means 211.

The primary acceleration means 136 preferably accelerates each of the sheets 02 to a first speed v1 and the secondary acceleration means 119 preferably accelerates each of the sheets 02 later to a second speed v2, for example the processing speed or printing speed, and optionally intermediately to an even higher third speed v3. As a result of this, no acceleration means 119; 136 has to be accelerated and decelerated between an idle state and the second speed v2 or even the third speed v3. Undesirably high accelerations are eliminated. Instead, it is sufficient for the primary acceleration means 136 to be accelerated and decelerated between an idle state and the first speed v1, for example. In one embodiment, the second acceleration means 119 is accelerated to the second speed v2 or even to the third speed v3, and is then decelerated again to a minimum speed.

In that case, it is not absolutely necessary for sheet processing machine 01 to be stopped when a sheet 02 has been compressed; instead, it can continue to run, for example without interruption, once compression system 147 has been re-tensioned. Preferably, sheet processing machine 01 has at least one transport diverter and/or ejection means and/or waste diverter for sheets 02, which is located downstream of the at least one compression system 147 with respect to the transport path provided for the transport of sheets 02.

The direction of rotation is selected such that a force exerted by the pushing device, for example by way of friction, is oriented opposite the transport direction of the sheet 02 and/or opposite its intended transport path. Processing machine 01 is halted, for example, when an improperly conveyed sheet 02 is detected and/or has been held and/or forced back by means of the auxiliary system 147 for holding and/or pushing sheets 02 back.
In an alternative or additional refinement, the sheet processing machine 01 preferably configured as a sheet-fed printing press 01 is preferably characterized in that the at least one primary acceleration means 136 is at the same time configured as a sheet alignment means for alignment with respect to the transverse direction A and/or with respect to a pivot position, and/or in that the at least one secondary acceleration means 119 is at the same time configured as a sheet alignment means for alignment with respect to the transverse direction A and/or with respect to a pivot position.

Preferred is a method for operating a processing machine 01 preferably configured as a sheet-fed printing press 01, in which sheets 02 coming from a pile 104 are singulated, and in which each of the sheets 02 is accelerated to a first speed v1 by means of at least one by a primary acceleration means 136, driven by a primary drive M101; M103, of a substrate supply system 100, and the primary drive M101; M103 is further preferably configured as a position-controlled electric motor M101; M103.

It is not necessary for sheets 02 to be held at the second speed v2 before being accelerated to the third speed v3. For example, a steady monotonic increase in the sheet speed from the first speed v1 to the third speed v3 is also possible. Sheets 02 are preferably transported along a transport path from substrate supply system 100 to at least one additional module 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000 of sheet processing machine 01, in particular to a printing module 600. Each of sheets 02 is preferably then transported by means of at least one drive M100; M200; 300; M400; M500; M550; M600; M700; M800; M900; 1000 of the at least one additional module 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000, in particular printing module 600, at a processing speed, in particular a printing speed, through the respective additional module 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000, in particular printing module 600, and during said transport is processed, in particular printed, in said respective additional module 200; 300; 400; 500; 550; 600; 700; 800; 900; 1000, in particular printing module 600.

Preferred in particular is thus a method in which sheets 02 are transported along a transport path from substrate supply system 100 to at least one printing module 600, and in which each of sheets 02 is then transported at a printing speed through the respective printing module 600 by means of at least one drive M600 of the at least one printing module 600, and during said transport is printed in said respective printing module 600, and in which the first speed v1 is lower than the printing speed.
Preferably, the method is alternatively or additionally characterized in that the printing speed is equal to the second speed v2 and/or in that the second speed v2 is greater than the first speed v1. Preferably, the method is alternatively or additionally characterized in that each of the sheets 02 is in contact at least at one point in time with both primary acceleration means 136 and secondary acceleration means 119. Preferably, the method is alternatively or additionally characterized in that a deceleration of the at least one primary acceleration means 136 does not cause a deceleration of the respective sheet 02 accelerated immediately previously by means of said primary acceleration means 136.
The method is alternatively or additionally characterized, for example, by the fact that a deceleration of the at least one secondary acceleration means 119 does not cause any deceleration of the respective sheet 02 accelerated immediately previously by means of said secondary acceleration means 119. However, to close a gap between sheets 02, an acceleration followed by a deceleration of a respective subsequent sheet 02 is preferably carried out by means of the at least one secondary acceleration means 119. The method is preferably alternatively or additionally characterized in that the at least one secondary acceleration means 119 is itself accelerated at least temporarily while a respective sheet 02 is accelerated from the first speed v1 to the second speed v2 and/or to the third speed v3, and is itself decelerated while a respective sheet 02 is decelerated from the third speed v3 to the second speed v2.
In an alternative or additional refinement, the method is preferably characterized in that at least one sheet sensor 164 detects the trailing edge of a preceding sheet 02 and generates a trailing edge signal, and in that at least one sheet sensor 164 detects the leading edge of a subsequent sheet 02 and generates a leading edge signal, and in that the acceleration and/or the deceleration of the respective, in particular subsequent sheet 02 is controlled and/or regulated by means of the at least one secondary acceleration means 119, factoring in the trailing edge signal and the leading edge signal. The method is alternatively or additionally characterized, for example, in that the at least one primary drive M101; M103 and the at least one secondary drive M102, are operated in synchronization with one another, in particular factoring in the trailing edge signal and/or the leading edge signal and/or in particular by means of the machine controller of sheet processing machine 02, such that a gap between a preceding sheet 02 and a subsequent sheet 02 is reduced and/or adjusted to a value that is within a predefined tolerance range around a target value. For example, a primary acceleration profile for the at least one primary acceleration means 136 and/or the primary drive M101; M103 thereof is stored, and/or a secondary acceleration profile for the at least one secondary acceleration means 119 and/or the secondary drive M102 thereof is stored. Preferably, the primary acceleration profile and/or further preferably the secondary acceleration profile is modified on the basis of signals from the at least one sheet sensor 164.
Once a respective sheet 02 has been passed on, the respective acceleration means 119; 136 is preferably decelerated again. The method is preferably characterized in that the at least one primary acceleration means 136 is decelerated, at least temporarily, while the at least one secondary acceleration means 119 and in particular also at least one sheet 02 is being accelerated, and/or in that the at least one secondary acceleration means 119 is decelerated, at least temporarily, while the at least one primary acceleration means 136 and in particular also at least one sheet 02 is being accelerated. Preferably, the method is characterized in that the at least one secondary acceleration means 119 is always operated at a speed v1; v2; v3 not equal to zero as long as said acceleration means is in contact with a sheet 02, and/or in that during a portion of a processing operation of sheet processing machine 01 in which at least three sheets 02 are singulated and accelerated, the at least one secondary acceleration means 119 is always operated at a speed v1; v2; v3 not equal to zero.
The method is preferably alternatively or additionally characterized in that the first speed v1 is at least 10%, more preferably at least 20%, and even more preferably at least 30% lower than the printing speed, and/or in that the first speed v1 amounts to at least 20%, preferably at least 30%, and more preferably at least 40% of the second speed v2, and/or in that the first speed v1 amounts to at most 80%, preferably at most 70%, and more preferably at most 60% of the second speed v2, and/or in that the third speed v3 is at least 10%, more preferably at least 20%, even more preferably at least 30%, and more preferably still at least 50% higher than the second speed v2.
Preferably, the method is alternatively or additionally characterized by the fact that the sheets 02 are printed in the at least one printing module 600 from above.
Preferably, the method is alternatively or additionally characterized by the fact that the sheets 02 are printed in the at least one printing module 600 from above by means of a non-impact printing method and/or by means of an inkjet printing method.
Preferably, the method is alternatively or additionally characterized by the fact that the substrate supply system 100 is configured as a module 100 of the sheet-fed printing press 01.
Preferably, the method is alternatively or additionally characterized in that the at least one primary acceleration means 136 is brought into contact with the sheets 02 on the underside of each sheet 02, in particular exclusively on the underside of each sheet, and/or in that the at least one secondary acceleration means 119 has at least one transport nip in which the sheets 02 are at least partially located while the at least one secondary acceleration means 119 is accelerating them to the second speed v2 and/or to the third speed v3, and/or is decelerating them to the second speed v2.
Preferably, the method is alternatively or additionally characterized in that during acceleration by means of the at least one primary acceleration means 136, a displacement of the respective sheet 02 with respect to the transverse direction A and/or a pivoting movement of the respective sheet 02 about a pivot axis that extends orthogonally to the transverse direction A and/or an adjustment of a phase position of the respective sheet 02 relative to at least one downstream component of the sheet-fed printing press 01 for transporting the sheets 02 takes place. Preferably, the method is alternatively or additionally characterized in that during acceleration by means of the at least one secondary acceleration means 119, a displacement of the respective sheet 02 with respect to the transverse direction A and/or a pivoting movement of the respective sheet 02 about a pivot axis that extends orthogonally to the transverse direction A and/or an adjustment of a phase position of the respective sheet 02 relative to at least one downstream component of the sheet-fed printing press 01 transporting the sheets 02 takes place. An adjustment of a phase position is understood, in particular, to mean that the movement of the sheet 02 along its transport path and the movement of the downstream component of the sheet-fed printing press 01 transporting the sheets 02 are synchronized with one another such that a predefined point on the sheet 02, for example the leading end thereof, enters into contact with a predefined point on the component transporting the sheet 02. For example, a movement of the sheet 02 along its transport path is positively and/or negatively accelerated and/or the component for transporting the sheet 02 is accelerated positively and/or negatively, in particular prior to its contact with said sheet 02.
Preferably, the method is alternatively or additionally characterized in that the respective sheet 02 is aligned with respect to its position along the transport path, for example relative to a preceding sheet 02 and/or relative to a phase position of a component of the sheet processing machine 01, by means of the at least one secondary acceleration means 119. Thus, for example, conveyance at a briefly increased speed and/or conveyance at a briefly reduced speed can influence this relative position. In that case, for example, the at least one primary acceleration means 136 accelerates the sheets to the processing speed and/or the printing speed, and the at least one secondary acceleration means 119 then performs only the fine alignment.
If, as described, multiple subsets of primary acceleration means 136 are provided as the at least one primary acceleration means 136, for example, the method is preferably alternatively or additionally characterized in that the subsets of primary acceleration means 136 execute different sequences of movements from one another. For example, at first the bottommost sheet 02 of a pile is in contact with acceleration means 136 of a plurality of the subsets. These subsets are then preferably accelerated synchronously at first, thereby moving said sheet 02 forward. Over time, the movement of said sheet 02 moves said sheet 02 out of contact with the first primary acceleration means 136 on the transport path of sheet 02 and subsequently out of contact with additional primary acceleration means 136. In a movement cycle of the primary acceleration elements 136 with respect to a sheet 02, at least the first primary acceleration means 136 with respect to the transport path of the sheet 02 is preferably decelerated and/or halted earlier than the last primary acceleration means 136 with respect to the transport path of the sheet 02. This prevents a subsequent sheet 02 from coming into contact with a primary acceleration means 136 that is moving at all or is moving too rapidly even though this subsequent sheet 02 is not yet supposed to be moving along the transport path at all. Thus, for example, some or all of the primary acceleration means 136 are always stopped as soon as a first sheet 02 is moved out of contact with them, and all of the primary acceleration means 136 are subsequently accelerated again collectively in a movement cycle related to a subsequent sheet 02.
If, as described, a plurality of spacers 144.1; 144.2 are arranged such that they are movable independently of one another, at least with respect to the vertical direction V, for example, the method is preferably alternatively or additionally characterized in that at first, the respective bottommost sheet 02 of the corresponding pile rests on a first spacer 144.1 with respect to the intended transport path for said sheet 02 and on a second spacer 144.2 with respect to the intended transport path for said sheet 02, without touching the primary acceleration means 136. At that time, said spacers 144.1; 144.2 are in their respective holding positions. The first spacer 144.1 and the second spacer 144.2 are then preferably lowered, thereby establishing contact between the bottommost sheet 02 and primary acceleration means 136. Primary acceleration means 136 accelerate the sheet along its transport path. The first spacer 144.1 along the intended transport path is then first raised, so that the sheet 02 that is initially the bottommost sheet is moved out of contact with at least one of the primary acceleration means 136. This prevents a subsequent sheet 02 from coming into contact with a primary acceleration means 136 that is moving at all or is moving too rapidly even though said subsequent sheet 02 is not yet supposed to be moving along the transport path at all. Thus, for example, some or all of the spacers 144; 144.1; 144.2 are always raised as soon as a first sheet 02 moves out of contact with them or is close to moving out of contact with them, and all of the spacers 144; 144.1; 144.2 are subsequently lowered again collectively in a movement cycle related to a subsequent sheet 02.
Preferably, at least one infeed system 300 is located downstream of a substrate supply system 100 and/or upstream of at least one coating unit 400; 600; 800 with respect to the provided transport path. The at least one infeed system 300 preferably serves to align sheets 02 as precisely as possible. This ensures that a subsequent processing of sheets 02 is carried out as precisely as possible relative to the sheets 02 and thus also relative to processes performed previously on the sheets 02. Depending upon the configuration and/or operation of the substrate supply system 100, the sheets 02 are preferably supplied to infeed system 300 in a shingled arrangement or singulated, for example. Preferably, the sheets 02 leave the infeed system 300 fully singulated.

The alignment means 301 comprises, for example, at least one alignment cylinder 302 and/or alignment roller 302, in particular drivable and/or driven, which is rotatable about a horizontal axis of rotation, for example, and which is pivotable about a pivot axis that is oriented in particular parallel to a vertical direction. Alternatively or additionally, the alignment cylinder 302 and/or alignment roller 302 is configured as movable, for example, partially or as a complete unit, in the transverse direction A, in particular for the purpose of moving sheets 02 in the transverse direction A and then moving itself back again. Infeed system 300 comprises at least one pressure roller or pressure cylinder, for example, by means of which a force can be exerted to force sheets 02 against said alignment cylinder 302 and/or alignment roller 302. By pivoting the alignment cylinder 302 and/or alignment roller 302 and/or by moving the alignment cylinder 302 and/or alignment roller 302 in the transverse direction A, the position of the respective sheet 02 can thereby be influenced, for example. Alternatively or additionally, alignment means 301 is equipped, for example, with a plurality of drivable and/or driven alignment cylinders 302 and/or alignment rollers 302, which are arranged offset relative to one another in the transverse direction A, for example. By actuating these alignment cylinders 302 and/or alignment rollers 302 differently, for example, sheets 02 can be pivoted about an axis that is oriented, for example, parallel to a vertical direction and/or to a direction orthogonal to the main surfaces of at least one sheet 02. With such alignment rollers 302 and/or alignment cylinders 302 that are pivotable and/or movable with respect to transverse direction A, for example, an infeed system 300 can be realized which operates without contact between sheets 02 on one side and front lay marks 127 and/or side lay marks on the other.
Alternatively or additionally, alignment means 301 has at least one stop, for example, also referred to as a mark 127. For example, alignment means 301 has at least one front lay mark 127 and/or at least one side lay mark. By moving the sheets against this front lay mark 127 and/or along this side lay mark, the respective sheet 02 is forced into a defined and known position, from which it can then be transported further.
The at least one infeed system 300 includes at least one inspection system 303, for example. This at least one inspection system 303 serves, for example, to detect the position of the respective sheet 02, for example, so that said position can subsequently be selectively adjusted, and/or so that information regarding the position of the respective sheet 02 can be used in subsequent units 200; 400; 500; 550; 600; 700; 800; 900; 1000. For example, information thus obtained is used to align the sheets 02 without stops and/or during further transport. The inspection system 303 comprises, for example, at least one and preferably a plurality of optical sensors, in particular, which are embodied, for example, as cameras and/or are preferably disposed such that they are movable mechanically, in particular in the transverse direction A.

For example, infeed system 300 has at least one pressure roller or pressure cylinder, by means of which a force can be exerted on sheets 02, pressing them against the at least one transport means 311. Infeed system 300 preferably comprises at least one transfer means 03 for sheets 02.

The primer facilitates, for example, the subsequent processing of the sheets 02, for example the application of at least one additional coating medium, in particular in the form of printing ink, and/or at least one additional coating medium, in particular in the form of ink, and/or at least one additional coating medium, in particular in the form of a finish coating.
In the following, details of a coating unit 400; 600; 800 configured by way of example as a flexo coating unit 400; 600; 800 will be described. This description applies similarly to other embodiments of the coating unit 400; 600; 800, provided no contradictions result. This flexo coating unit 400; 600; 800 is represented by way of example as a priming unit 400. The description can be applied similarly to printing units 600 and finish coating units 800, provided no contradictions result.
The flexo coating unit 400; 600; 800 preferably has at least one coating medium reservoir 401; 601; 801. In the case of a priming unit 400, the coating medium reservoir 401; 601; 801 is more preferably a primer reservoir 401 and/or in the case of a printing unit 600, said reservoir is a printing ink reservoir 601 or ink reservoir 601, and/or in the case of a finish coating unit 800 said reservoir is a finish coating reservoir 801.

For supplying the forme cylinder 402; 602; 802 and/or the coating forme with coating medium, in particular, at least one supply roller 403; 603; 803 is preferably provided, which is further preferably configured as an anilox roller 403; 603; 803 and/or which has a saucer structure on its lateral surface and preferably is and/or can be placed in contact with the forme cylinder 402; 602; 802. Alternatively, between supply roller 403; 603; 803 and application cylinder 402; 602; 802, at least one additional transfer roller for coating medium may also be provided. In the case of a priming unit 400, for example, the supply roller 403; 603; 803 is configured as a primer supply roller 403, and/or in the case of a printing unit 600 said supply cylinder is configured as a printing ink supply roller 603 or an ink supply roller 603, and/or in the case of a finish coating unit 800 said supply roller is configured as a finish coating supply roller 803. At least one intermediate reservoir 404; 604; 804 for coating medium is preferably in contact and/or in operative connection with the supply roller 403; 603; 803. Said intermediate reservoir is preferably configured as a chamber doctor blade 404; 604; 804. Thus, at least one chamber doctor blade 404; 604; 804 is preferably in contact and/or in operative connection with the supply roller 403; 603; 803, which is configured in particular as anilox roller 403; 603; 803. The intermediate reservoir 404; 604; 804 preferably configured as chamber doctor blade 404; 604; 804 is preferably connected via at least one supply line 406; 606; 806, and more preferably also via at least one drain line 407; 607; 807, to the at least one coating medium reservoir 401; 601; 801. The supply line 406; 606; 806 and/or the drain line 407; 607; 807 is preferably in operative connection with at least one pump device. Preferably, a device for the assisted and/or automated and/or semi-automated installation and/or removal of the supply roller 403; 603; 803 is provided.
At least one counterpressure means 408; 608; 808 is preferably provided, which serves as a counter-bearing for the application of the coating medium to the sheets 02. The at least one counterpressure means 408; 608; 808 is embodied, for example, as impression cylinder 408; 608; 808. Alternatively, the at least one counterpressure means 408; 608; 808 is embodied as a counterpressure belt. The transport path provided for sheets 02 preferably extends between the forme cylinder 402; 602; 802 and the counterpressure means 408; 608; 808, in particular impression cylinder 408; 608; 808. Forme cylinder 402; 602; 802, on one side, and counterpressure means 408; 608; 808 on the other together preferably form at least one coating position 409; 609; 809, which, in particular in the case of a priming unit 400, is embodied as a priming position 409, and/or in the case of a printing unit 600 is embodied as a print position 609 and/or in the case of a finish coating unit 800 is embodied as finish coating position 809. The axis of rotation of impression cylinder 408; 608; 808 preferably extends at least intermittently and more preferably perpetually parallel to the transverse direction A.
Coating unit 400; 600; 800 is configured, for example, as a coating unit 400; 600; 800 that applies a coating from above and/or is capable of applying a coating from above, or alternatively is configured, for example, as a coating unit 400; 600; 800 that applies a coating from below and/or is capable of applying a coating from below. The choice is preferably based upon the way in which other units of the processing machine 01 are configured and/or arranged and/or upon which side of the sheets 02 will be processed.
If coating unit 400; 600; 800 is configured both as a coating unit 400; 600; 800 that applies a coating from above and/or is capable of applying a coating from above and as a flexo coating unit 400; 600; 800, the counterpressure means 408; 608; 808 is preferably located below the application cylinder 402; 602; 802 and/or at least partially below the supply roller 403; 603; 803, and/or the application cylinder 402; 602; 802 is preferably located above the counterpressure means 408; 608; 808 and/or at least partially below the supply roller 403; 603; 803, and/or the supply roller 403; 603; 803 is preferably located at least partially above the application cylinder 402; 602; 802 and/or at least partially above the counterpressure means 408; 608; 808. If coating unit 400; 600; 800 is configured both as a coating unit 400; 600; 800 that applies a coating from below and/or is capable of applying a coating from below and as a flexo coating unit 400; 600; 800, the counterpressure means 408; 608; 808 is preferably located above the application cylinder 402; 602; 802 and/or at least partially above the supply roller 403; 603; 803, and/or the application cylinder 402; 602; 802 is preferably located below the counterpressure means 408; 608; 808 and/or at least partially above the supply roller 403; 603; 803, and/or the supply roller 403; 603; 803 is preferably located at least partially below the application cylinder 402; 602; 802 and/or at least partially below the counterpressure means 408; 608; 808.
Supply roller 403; 603; 803 is preferably arranged such that it can be thrown off of and/or moved up to the application cylinder 402; 602; 802. For this purpose, a corresponding first displacement mechanism, in particular a lifting mechanism, is preferably provided. During this movement, supply roller 403; 603; 803 is preferably moved while the rotational axis of the application cylinder 402; 602; 802 remains unchanged. Preferably, however, application cylinder 402; 602; 802 can also be thrown off of and/or moved up to counterpressure means 408; 608; 808, in particular impression cylinder 408; 608; 808, more preferably jointly with supply roller 403; 603; 803. For this purpose, a corresponding second displacement mechanism, in particular a lifting mechanism, is preferably provided, which more preferably is capable of moving an assembly that comprises both the application cylinder 402; 602; 802 and the supply roller 403; 603; 803, and more preferably also comprises the first displacement mechanism.
At least one diagonal register adjustment device is preferably provided, in particular as a component of the respective coating unit 400; 600; 800. The at least one diagonal register adjustment device comprises, for example, at least one and more preferably two rotary bearings, in particular radial bearings, which are preferably displaceable with respect to the transport direction T intended for sheets 02, and which serve to rotatably mount the application cylinder 402; 602; 802. If said at least one rotary bearing is moved with at least one component in or opposite the transport direction T, or if these two rotary bearings are moved at least with different components in or opposite the transport direction T, an inclined position of the rotational axis of the application cylinder 402; 602; 802 will result. This results in a more inclined transfer of coating medium onto the sheet or sheets 02 than before, and the angular position can preferably be selectively influenced. Alternatively or additionally, the at least one diagonal register adjustment device preferably has at least one positioning device located on the application cylinder 402; 602; 802, by means of which the position of the covering relative to the lateral surface of the application cylinder 402, 602; 802 is and/or can be fixed. For example, the at least one diagonal register adjustment device has at least one pivotable suspension rail for coverings, in which the at least one covering is and/or can be suspended, for example, by means of a suspension arm, in particular a leading suspension arm. The at least one diagonal register adjustment device can preferably be operated automatically.
The coating unit 400; 600; 800 preferably has at least one incoming transport means 411; 611; 811. The at least one incoming transport means 411; 611; 811 is preferably located upstream of a first coating position 409; 609; 809 of the respective coating unit 400; 600; 800 along the transport path provided for sheets 02 and/or with respect to the transport direction T. The at least one incoming transport means 411; 611; 811 serves, for example, to feed sheets 02 at least to the first coating position 409; 609; 809, in particular from an intake 412; 612; 812 into the coating unit 400; 600; 800. The at least one incoming transport means 411; 611; 811 thus serves, for example, to feed sheets 02 to the priming position 409, in particular from an intake 412 into the priming unit 400, and/or to feed sheets 02 to the print position 609, in particular from an intake 612 into the printing unit 600, and/or to feed sheets 02 to the finish coating position 809, in particular from an intake 812 into the finish coating unit 800. The at least one incoming transport means 411; 611; 811 is preferably embodied as a suction transport means 411; 611; 811, in particular as a suction belt 411; 611; 811 and/or as a suction box belt 411; 611; 811 and/or as a roller suction system 411; 611; 811. The description relating to suction transport means in the foregoing and in the following preferably applies accordingly.
The at least one incoming transport means 411; 611; 811 is configured, for example, as an upper suction transport means 411; 611; 811, the suction inlets or suction openings of which preferably point at least substantially downward and/or the suction effect of which is preferably directed at least substantially upward. Alternatively or additionally, the at least one incoming transport means 411; 611; 811 is configured as a lower suction transport means 411; 611; 811, the suction openings or suction openings of which preferably point at least substantially upward and/or the suction effect of which is preferably directed at least substantially downward. The choice is dependent, for example, upon upstream units and/or upon the mode of operation of the coating unit 400; 600; 800. Alternatively, coating unit 400; 600; 800 is configured, for example, without incoming transport means. In that case, a unit disposed stream of said coating unit is preferably configured such that sheets 02 can be transferred directly to the coating position 409; 609; 809. This is possible, for example, if the unit arranged upstream of said coating unit is configured as a transport system 700, in particular a transport unit 700 or a transport module 700.
Coating unit 400; 600; 800 preferably comprises at least one outgoing transport means 417; 617; 817. The at least one outgoing transport means 417; 617; 817 is preferably disposed downstream of the coating position 409; 609; 809 along the transport path provided for sheets 02 and/or with respect to the transport direction T. The at least one outgoing transport means 417; 617; 817 serves, for example, to convey sheets 02 away from the coating position 409; 609; 809, in particular to an outlet 413; 613; 813 of the coating unit 400; 600; 800 and/or after a processing of the respective sheet 02 in the coating unit 400; 600; 800. The at least one outgoing transport means 417; 617; 817 therefore serves, for example, to convey sheets 02 away from the priming position 409, in particular to an outlet 413 of the primer unit 400, and/or to convey sheets 02 away from the print position 609, in particular to an outlet 613 of the printing unit 600, and/or to convey sheets 02 away from the finish coating position 809, in particular to an outlet 812 of finish coating unit 800. The at least one outgoing transport means 417; 617; 817 is preferably embodied as a suction transport means 417; 617; 817, in particular as a suction belt 417; 617; 817 and/or as a suction box belt 417; 617; 817 and/or as a roller suction system 417; 617; 817. The description relating to suction transport means in the foregoing and in the following preferably applies accordingly.
The at least one outgoing transport means 417; 617; 817 is configured, for example, as an upper suction transport means 417; 617; 817, the suction inlets or suction openings of which preferably point at least substantially downward and/or the suction effect of which is preferably directed at least substantially upward. Alternatively or additionally, the at least one outgoing transport means 417; 617; 817 is configured as a lower suction transport means 417; 617; 817, the suction inlets or suction openings of which preferably point at least substantially upward and/or the suction effect of which is preferably directed at least substantially downward. The choice is dependent, for example, upon whether the coating unit 400; 600; 800 is configured as a coating unit 400; 600; 800 that applies a coating from above and/or is capable of applying a coating from above or as a coating unit 400; 600; 800 that applies a coating from below and/or is capable of applying a coating from below. A coating unit 400; 600; 800 that applies a coating from above and/or is capable of applying a coating from above preferably has an outgoing transport means 417; 617; 817 configured as a lower suction transport means 417; 617; 817, and/or a coating unit 400; 600; 800 that applies a coating from below and/or is capable of applying a coating from below preferably has an outgoing transport means 417; 617; 817 configured as an upper suction transport means 417; 617; 817. This preferably prevents a freshly applied coating from being damaged by the outgoing transport means 417; 617; 817. Alternatively, coating unit 400; 600; 800 is formed, for example, without outgoing transport means. In that case, a unit located downstream of said coating unit is preferably configured such that sheets 02 can be transferred directly from the coating position 409; 609; 809. This is possible, for example, if the unit located downstream of said coating unit is configured as a transport system 700 or transport means 700, in particular a transport unit 700 or a transport module 700.
Coating units 400; 600; 800 configured as flexo coating units 400; 600; 800 each have, for example, precisely one coating position 409; 609; 809. For application of a plurality of different coating media, an appropriate multiple number of flexo coating units 400; 600; 800, in particular flexo printing units 600, are preferably provided.
For example, each of the at least one coating units 400; 600; 800 configured as a flexo coating unit 400; 600; 800 has associated with it at least one, in particular integrated, drying system 500 or drying device 506 dedicated uniquely to it. Said drying system or device is aligned, for example, toward the at least one outgoing transport means 417; 617; 817 of said respective coating unit 400; 600; 800 configured as a flexo coating unit 400; 600; 800.
In the following, details regarding a coating unit 400; 600; 800 configured as a non-impact coating unit 400; 600; 800, in particular a non-impact coating module 400; 600; 800, i.e., for example, as a jet coating unit 400; 600; 800, in particular as an inkjet coating unit 400; 600; 800 and/or jet coating module 400; 600; 800, in particular as inkjet coating module 400; 600; 800, will be provided. Insofar as this does not result in contradictions, what has been described can be applied similarly to other embodiments of the coating unit 400; 600; 800, in particular to other non-impact printing units 600. The jet coating unit 400; 600; 800 preferably has at least one print head 416; 616; 816. The at least one print head 416; 616; 816 is configured, for example, as an inkjet print head 416; 616; 816.
The jet coating unit 400; 600; 800 will be described in the context of a jet printing unit 600, in particular an inkjet printing unit 600 and/or jet printing module 600, by way of example. However, the same applies similarly to a jet primer unit 400, in particular jet priming module 400, and/or a jet finish coating unit 800, in particular jet finish coating module 800.
The at least one jet coating unit 400; 600; 800, in particular inkjet printing unit 600, of processing machine 01 in turn preferably has at least one coating position 409; 609; 809, in particular print position 609. In this context, a coating position 409; 609; 809, in particular print position 609, including in the case of a non-impact coating unit 400; 600; 800, is preferably understood as an entire region in which contact between a respective coating medium, in particular ink, and a respective sheet 02 is or can be produced. The term coating position 409; 609; 809, in particular print position 609, is also used when the coating medium is applied to the sheet 02 without contact between sheet 02 and a component that transfers the coating medium, for example by freely moving coating medium, for example flying droplets of coating medium, striking the sheet 02. A coating position 409; 609; 809, in particular print position 609, preferably encompasses all the areas intended for the impact of a specific coating medium assigned in particular to that coating position 409; 609; 809, in particular print position 609, on the sheet 02. In the case of a printing unit 600 that operates by the inkjet printing method, for example, a print position 609 comprises all the areas that are intended for impact of a black ink, for example, on a first side of the sheet 02.
The at least one coating unit 400; 600; 800, in particular printing unit 600, preferably has a plurality of coating positions 409; 609; 809, in particular print positions 609, to each of which a respective coating medium is assigned, for example at least four coating positions 409; 609; 809, in particular print positions 609, preferably at least five coating positions 409; 609; 809, in particular print positions 609, more preferably at least six coating positions 409; 609; 809, in particular print positions 609, and even more preferably at least seven coating positions 409; 609; 809, in particular print positions 609.
Coating units 400; 600; 800 configured as non-impact coating units 400; 600; 800, in particular inkjet coating units 400; 600; 800, thus preferably each have at least a plurality of coating positions 409; 609; 809, in particular at least four, preferably at least five, more preferably at least six and even more preferably at least seven. Only one such coating unit 400; 600; 800 is then required for the application of multiple different coating media, for example. Alternatively, an appropriate plural number of non-impact coating units 400; 600; 800, in particular non-impact printing units 600, are provided.
Particularly in non-impact coating units 400; 600; 800, in particular in jet coating units 400; 600; 800 such as inkjet printing units 600, for example, water-based coating media and/or wax-based coating media and/or UV-curing coating media are used, for example. Any dryer units 500 that may be provided are preferably configured as adapted to the corresponding coating medium, and thus have energy sources in the form of infrared radiation sources and/or UV radiation sources and/or hot air sources and/or electron beam sources, for example.
Each coating position 409; 609; 809, in particular print position 609, preferably has at least one application position 418; 618; 818. Each application position 418; 618; 818 is preferably assigned to at least one image-producing device 416; 616; 816, in particular at least one print head 416; 616; 816 and more preferably at least one row of print heads. Each application position 418; 618; 818 preferably extends in the transverse direction A, more preferably over the entire working width of the processing machine 01. In the case of an inkjet printing machine 01, the at least one image producing device 416; 616; 816 is preferably configured as at least one print head 416; 616; 816, in particular one inkjet print head 416; 616; 816. The at least one coating unit 400; 600; 800 preferably has at least two print heads 416; 616; 816. For example, the at least one coating unit 400; 600; 800 is characterized in that the at least two print heads 416; 616; 816 are configured as print heads 416; 616; 816 formed for a non-impact printing process, and more preferably in that the at least two print heads 416; 616; 816 are configured as inkjet print heads 416; 616; 816. Image-producing devices 416; 616; 816 such as print heads 416; 616; 816 typically have limited dimensions, in particular in the transverse direction A. This results in a limited area of the sheet 02 onto which coating medium can be applied by a respective print head 416; 616; 816. A plurality of image-producing devices 416; 616; 816 or print heads 416; 616; 816 are therefore typically arranged one behind the other in the transverse direction A. Such print heads 416; 616; 816 arranged one behind the other in the transverse direction A are referred to as a print head row. Print head rows may be either discontinuous or continuous. In the exceptional case of a print head 416; 616; 816 extending over the entire working width, said print head should likewise be regarded as a print head row, in particular as a continuous print head row.
A plurality of application positions 418; 618; 818 are associated with at least one coating medium, for example, such that, for example, two continuous rows or two double rows of print heads 416; 616; 816 eject or are capable of ejecting the same coating medium. This is useful, for example, for increasing the resolution of a printed image and/or for increasing the speed of a coating process. This plurality of application positions 418; 618; 818 then together form the coating position 409; 609; 809, in particular the print position 609, associated with that coating medium. A resolution with respect to transverse direction A is preferably 1200 dpi (1200 dots per inch). The resolution with respect to transport direction T can be influenced by the number of print heads 416; 616; 816 arranged one behind the other and/or by the transport speed of the sheets 02.
A coating unit 400; 600; 800 comprises, for example, only one coating position 409; 609; 809, in particular print position 609, for the color black, for example. Preferably, however, the at least one coating unit 400; 600; 800 has a plurality of coating positions 409; 609; 809, in particular print positions 609, as described. Spatially, the coating positions 409; 609; 809, in particular print positions 609, may be immediately adjacent to one another or may be spaced apart from one another, for example separated by color. The term coating position 409; 609; 809, in particular print position 609, is also meant to include a section that contains a plurality of successive application positions 418; 618; 818 of the same color, e.g. without interruption by another color. However, if one or more application positions 418; 618; 818 of one color is/are separated by at least one or more application positions 418; 618; 818 of at least one other color along the transport path provided for sheets 02, then in this sense said application positions act as two different coating positions 409; 609; 809, in particular print positions 609. In the case of only one coating position 409; 609; 809, in particular print position 609, said position acts as both the first and the last coating position 409; 609; 809, in particular print position 609, of the relevant coating unit 400; 600; 800. In the case of an indirect inkjet printing process, for example, a coating position 409; 609; 809, in particular print position 609, is an area of contact between a transfer body and the respective sheet 02.
The jet coating unit 400; 600; 800 has at least one counterpressure means 408; 608; 808, for example, however said counterpressure means preferably does not serve to clamp the sheets 02, but only to hold them in position. At least one such counterpressure means 408; 608; 808 is configured, for example, as a counterpressure belt 408; 608; 808 and/or as a transport means 411; 417; 611; 617; 811; 817, in particular suction transport means 411; 417; 611; 617; 811; 817. With particular preference, the jet coating unit 400; 600; 800, as viewed in the direction of transport T, has only one transport means 411; 417; 611; 617; 811; 817, which is further preferably configured as suction transport means 411; 417; 611; 617; 811; 817 and which at the same time is configured to act as incoming transport means 411; 611; 811 and/or as counterpressure means 408; 608; 808 and/or as outgoing transport means 417; 617; 817.
If coating unit 400; 600; 800 is configured as jet coating unit 400; 600; 800, it is preferably likewise configured as a coating unit 400; 600; 800 that applies a coating from above and/or is capable of applying a coating from above, in particular due to the configurations of print heads 416; 616; 816 that are typically used.
