It is the object of the present invention to devise a sheet processing machine, a method for inspecting at least one remaining portion of at least one sheet processed by a shaping device, and a method for inspecting a sheet.
The object is achieved according to the present invention by the provision that at least one inspection device is configured to ascertain an actual state of the at least one sheet of the sheets downstream from the separation device in the transport direction (T) of the sheets. The at least one inspection device ascertains an actual state of the at least one sheet downstream from the separation device in the transport direction (T), and the actual state of the at least one sheet is compared to a desired state of the at least one sheet. The at least one inspection device ascertains the actual state of the at least one sheet of the sheets downstream from the separation device in the transport direction (T) of the sheets.
A sheet processing machine preferably comprises a shaping device for processing sheets. The shaping device preferably comprises at least one shaping point. The sheet processing machine preferably comprises at least one separation device. The separation device is preferably configured to remove at least one offcut piece from at least one sheet. The separation device is preferably configured to remove the at least one offcut piece from the at least one sheet. The at least one separation device is preferably arranged along a transport path provided for the transport of the sheets, downstream from the at least one shaping point. In the transport direction of the sheets downstream from the separation device, at least one inspection device is preferably configured to ascertain an actual state of the at least one sheet of the sheets. At least one inspection device for inspecting at least one remaining portion of the at least one sheet processed by the shaping device, comprising at least one multiple-up, is preferably arranged in the transport direction of the sheets downstream from the separation device.
A method for inspecting the at least one remaining portion of the at least one sheet of sheets which is processed by the shaping device in the sheet processing machine is preferred. The at least one sheet comprises at least one multiple-up. The at least one sheet is preferably processed in the at least one shaping device of the sheet processing machine. At least one offcut piece is preferably removed from the at least one sheet downstream from the shaping device in the transport direction of the sheets. The at least one offcut piece is preferably removed from the at least one sheet by at least one separation device. The at least one inspection device preferably ascertains an actual state of the at least one sheet downstream from the separation device in the transport direction. The actual state of the at least one sheet is compared to a desired state of the at least one sheet.
As an alternative or in addition, a method for inspecting at least one sheet of sheets by way of at least one inspection device in a sheet processing machine is preferred. The at least one sheet detected by the inspection device preferably comprises at least two multiple-ups and at least one sheet opening. The at least one inspection device preferably ascertains an actual state of the at least one sheet. The actual state of the at least one sheet is compared to a desired state of the at least one sheet.
This yields the advantage that remaining offcut pieces and/or portions of remaining offcut pieces can be easily removed from the sheets, downstream from the shaping device in the transport direction of the sheets, by at least one separation transport means and/or by the separation device, in particular by gravity and, additionally or alternatively, by at least one preferred embodiment of the separation device and/or of the separation transport means and, additionally or alternatively, by preferred embodiments of the separation device and/or of the separation transport means. If offcut pieces and/or portions of offcut pieces remain in the sheet downstream from the separation device in the transport direction of the sheets, these at least partially remaining offcut pieces can cause problems during the further course of the treatment and/or of the transport of the sheets along a transport path of sheets in the transport direction, for example when the delivery pile is formed. By detecting the respective sheet by way of the inspection device, it is possible to identify relevant sheets with at least one partially remaining offcut piece and, for example, to additionally divert them from the regular transport path and/or, for example, to separate them from sheets without at least partially remaining offcut pieces. In particular, the relevant sheets are advantageously identified and diverted and/or separated from sheets without at least partially remaining offcut pieces. In this way, the process reliability of the sheet processing machine is increased.
Advantageously, the comparison of the actual state of the respective, preferably the at least one, sheet to the desired state of the relevant, preferably the at least one, sheet is used to inspect the processing operation of the particular sheet by the shaping device, for example at least one die cutting operation and/or at least one creasing operation and/or at least one embossment and/or at least one perforation. In addition, or as an alternative, the comparison of the actual state of the respective, preferably the at least one, sheet to the desired state of the relevant, preferably the at least one, sheet is used to inspect and/or check a removal, preferably a complete removal, of at least one offcut piece and/or of an at least partially present offcut piece from the sheet in question.
The sheets are preferably inspected within the sheet processing machine, in particular without at least one sheet being removed and/or having to be removed, for example randomly, for the inspection from the sheet processing machine. As an alternative, the sheets are inspected outside the sheet processing machine, preferably after at least one processing operation of the sheets in the sheet processing machine.
The sheets are preferably inspected downstream from the separation device, in particular immediately following the separation device. In this way, it is preferably ensured that the sheet is inspected after the respective sheet has been processed by the shaping device and after the at least one offcut piece has been removed. It is preferably possible to identify a defective sheet, for example upstream from a further processing device, for example a separation of the individual multiple-ups and/or upstream from a delivery unit, arranged downstream from the separation device in the transport direction, and, for example, to channel it out upstream from the further processing device and/or upstream from the delivery unit in the transport direction.
As a result of a preferably orthogonal arrangement of the inspection device with respect to the transport path provided for the transport of sheets, sheets can preferably be inspected without the transport of sheets being at least partially impaired along the transport path.
In a preferred embodiment, the sheet processing machine comprises the at least one delivery unit. The sheet processing machine preferably comprises at least one sheet diverter for channeling out at least one sheet. The at least one sheet diverter is preferably configured to channel out at least one sheet. The at least one sheet diverter is preferably configured to generate a change of the transport path provided for the transport of sheets. Sheets can then preferably be sorted out and/or removed for sampling purposes, preferably without influencing a delivery pile and/or further treatment and/or processing of the sheets along the transport path.
In a preferred embodiment, data about the respective transported sheets can be stored and, for example, a report about the quality of the sheets can be created and be evaluated. In particular, the data is preferably stored and, for example, the report is created and evaluated. The inspection device is preferably configured to store and evaluate data about the at least one sheet and respective further transported sheets and to create at least one report about a quality of the respective transported sheets. It is thus possible, for example, to exactly set, and preferably to guarantee, a desired and/or required quality of the sheets processed by the shaping machine, for example in a delivery pile of the delivery unit.
A preferred embodiment of the sheet processing machine enables particularly gentle and/or exact guidance of sheets along the transport path. The sheets can preferably be transported flat, the sheets are, in particular, transported flat, and are protected in the process. In a preferred embodiment, the sheets are at least partially transported in a hanging state in the sheet processing machine. Preferably, at least one transport means configured as a selective transport means, which is preferably configured for the hanging transport of sheets, is arranged along the transport path of sheets, following the at least one separation transport means. The transport means, which is preferably configured as a selective transport means, is preferably configured to transport the sheets in a hanging state. Advantageously, a preferred embodiment of the sheet processing machine protects at least one print image applied to the sheet, which is preferably applied to the relevant sheet from beneath, during the transport of the respective sheet. Another advantage is preferably that a hanging guidance of sheets allows the selective transport means and/or the separation transport means to be easily maintained from beneath, even in the case of large working widths. Gentle handling of sheets is in particular advantageous in connection with corrugated cardboard.
In an advantageous embodiment, at least one imbricating device, which comprises at least one transport means configured as an upper suction transport means and/or as a sheet infeed means, is arranged between the at least one selective transport means and/or the at least one sheet diverter on one hand and the at least one sheet decelerating means on the other hand, along the transport path provided for the transport of sheets. Sheets having particularly large dimensions can thus be deposited and/or are deposited onto the delivery pile and/or can be deposited and/or are deposited in particularly rapid succession. As an alternative or in addition, the sheet processing machine is preferably characterized in that the at least one upper suction transport means of the at least one imbricating device is configured as a passively driven suction transport means. This facilitates imbrication and protects the sheets. Another advantage of an imbricating device is, in particular, that excessive accelerations of sluggish components are not necessary.
This allows energy to be saved and wear and tear to be reduced and/or saves energy and reduces wear and tear, for example. Another advantage is that a succeeding sheet can at least partially overtake and/or, for example, be configured to overtake a leading sheet, thereby enabling relatively smooth movements of the sheets.
Preferably, a degree of tool wear of at least one tool of the at least one shaping device is ascertained, in particular from the comparison of the actual state of the at least one sheet to the desired state of the relevant, preferably the at least one, sheet. In this way, it is preferably possible to detect wear and/or tear of the tool at an early stage. It is preferably possible to replace the tool before it is entirely worn and/or completely torn and/or before the tool breaks. As an alternative, premature replacement of the tool, for example if the wear and/or tear is less than expected, can thus preferably be prevented and/or is prevented, for example.
Preferably, a degree of wear of at least one surface of at least one counterpressure cylinder of the at least one shaping device is ascertained, in particular from the comparison of the actual state of the at least one sheet to the desired state of the relevant, preferably the at least one, sheet. In this way, it is preferably possible to detect wear and/or tear of the surface of the counterpressure cylinder at an early stage. It is preferably possible to replace the surface of the counterpressure cylinder before it is entirely worn and/or completely torn. As an alternative, premature replacement of the surface of the counterpressure cylinder, for example if the wear and/or tear is less than expected, can thus preferably be prevented and/or is prevented, for example.
In a preferred embodiment, the sheet processing machine comprises at least one application mechanism for applying at least one print image to the at least one sheet. The at least one application mechanism is preferably configured to apply at least one print image to the at least one sheet. By way of the inspection device, in particular by way of an evaluation means, it is preferably possible to evaluate at least one color register of the at least one print image of the at least one sheet and/or to at least compare the at least one print image of the at least one sheet to at least one sheet opening and/or at least one inner contour and/or at least one outer contour of the particular sheet.
The sheet is preferably inspected with respect to the processing of the particular sheet by the shaping device and, additionally or alternatively, the at least one print image applied to the particular sheet and, additionally or alternatively, the at least one print image applied to the particular sheet relative to the at least one sheet opening and/or the at least one inner contour and/or the at least one outer contour of the particular sheet.

Above and below, when application fluids and/or inks and/or printing inks are mentioned, this in particular also includes colorless coating materials. Above and below, when application fluids and/or inks and/or printing inks are mentioned, this preferably also includes, in particular, agents for pretreating (priming or precoating) the printing substrate 02. The term printing fluid and the term coating agent shall be understood as synonymous alternatives to the term application fluid. A respective application fluid is preferably not gaseous. A respective application fluid is preferably liquid and/or powdered.
A processing machine 01 is preferably configured as a printing press 01 and/or as a shaping machine 01, in particular a die-cutting machine 01. The printing press 01 is configured as a flexo printing press 01, for example.
The processing machine 01 is preferably referred to as a printing press 01 when it comprises at least one printing couple 614 and/or at least one printing unit 600, in particular regardless of whether it comprises additional units for processing substrate 02. A processing machine 01 configured as a printing press 01 also comprises, for example, at least one additional such unit 900, for example at least one shaping unit 900, which is preferably configured as a die-cutting unit 900, more preferably as a die-cutting device 900. The processing machine 01 is preferably referred to as a shaping machine 01 if it comprises at least one shaping mechanism 914 and/or at least one shaping unit 900, in particular regardless of whether it comprises additional units 600 for processing substrate 02.

In a preferred embodiment, the processing machine 01, in particular a sheet processing machine 01, preferably comprises a unit 100 configured as a sheet feeder 100 and/or at least one application mechanism 614 for applying at least one print image onto substrate 02. Thus, if the processing machine 01 comprises at least one printing couple 614 and/or at least one printing unit 600, and also comprises at least one shaping mechanism 914 and/or at least one shaping unit 900, it is configured both as a printing press 01 and as a shaping machine 01. If the processing machine 01 comprises at least one printing couple 614 and/or at least one printing unit 600, and also comprises at least one die-cutting mechanism 914 and/or at least one die-cutting unit 900 and/or at least one die-cutting device 900, it is accordingly configured both as a printing press 01 and as a shaping machine 01, in particular a die-cutting machine 01.
The processing machine 01 is 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 a sheet-format printing substrate 02. For example, the sheet processing machine 01 is configured as a sheet-fed printing press 01 and/or as a sheet-fed shaping machine 01 and/or as a sheet-fed die-cutting machine 01. The 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 made of corrugated cardboard 02, in particular sheet-format printing substrate 02 made of corrugated cardboard 02. The processing machine 01 is further preferably configured as a sheet-fed printing press 01, in particular as a corrugated cardboard sheet printing press 01, i.e., as a printing press 01 for coating and/or printing sheet-format substrate 02 or sheets 02 made of corrugated cardboard 02, in particular sheet-format printing substrate 02 made of corrugated cardboard 02. The printing press 01 is configured as a printing press 01 that operates according to a printing forme-based printing method, for example.
Unless an explicit distinction is made, the term sheet-format substrate 02, in particular printing substrate 02, specifically sheet 02, shall generally include any flat substrate 02 present in the form of sections, i.e., including substrates 02 in tabular form or panel form, i.e., including boards or panels. The sheet-format substrate 02 or sheet 02 thus defined is made, for example, of paper or paperboard, i.e., as a sheet of paper or paperboard, or by sheets 02, boards, or optionally panels made of plastic, cardboard, glass, or metal. More preferably, the substrate 02 is corrugated cardboard 02, in particular corrugated cardboard sheets 02. The at least one sheet 02 is preferably configured as corrugated cardboard 02. A thickness of a sheet 02 shall preferably be understood to mean a dimension orthogonal to a largest surface area of the sheet 02. This largest surface area is also referred to as the main surface area. For example, the thickness of the sheets 02 is at least 0.1 mm, more preferably at least 0.3 mm, and still more preferably at least 0.5 mm. Considerably greater thicknesses are also customary, especially in the case of corrugated cardboard sheets 02, for example at least 4 mm or also 10 mm and more. Corrugated cardboard sheets 02 are relatively stable and are therefore not very flexible. Corresponding adjustments to the processing machine 01 therefore facilitate the processing of sheets 02 of great thickness.
The respective, preferably the at least one, sheet 02 is preferably made of paper or cardboard or paperboard. According to DIN 6730, paper is a flat material, consisting mainly of fibers derived from vegetable sources, which is formed by the dewatering of a fiber suspension on a sieve. In the process, a card web is created, which is subsequently dried. The basis weight of paper is preferably a maximum of 225 g/m2. According to DIN 6730, cardboard is a flat material, consisting mainly of fibers derived from vegetable sources, which is formed by the dewatering of a fiber suspension on a sieve or between two sieves. The fiber structure is compressed and dried. Cardboard is preferably manufactured from cellulose by gluing or pressing. Cardboard is preferably configured as solid board or corrugated cardboard 02. Above and below, corrugated cardboard 02 is cardboard made of one or more layers of corrugated paper that is glued to one layer or between multiple layers of another, preferably smooth, paper or cardboard. The basis weight of cardboard is preferably more than 225 g/m2. Above and below, the term paperboard preferably refers to a sheet material that is preferably primed on one side and made of paper, preferably having a basis weight of at least 150 g/m2 and no more than 600 g/m2. Paperboard preferably has high strength relative to paper.
The processing machine 01 preferably comprises multiple units 100; 300; 600; 700; 900; 1000. A unit in this context shall preferably be understood to mean a group of devices that cooperate functionally, in particular in order to carry out a preferably self-contained processing operation of sheets 02.

Each unit 100; 300; 600; 700; 900; 1000 preferably comprises at least one drive control system and/or at least one drive controller, which is assigned to the respective at least one drive of the particular unit 100; 300; 600; 700; 900; 1000. The drive control systems and/or drive controllers of the individual units 100; 300; 600; 700; 900; 1000 can preferably be operated individually and independently of one another. More preferably, the drive control systems and/or drive controllers of the individual units 100; 300; 600; 700; 900; 1000 are linked and/or can be linked in terms of circuitry, in particular by means of at least one BUS system, to one another and/or to a machine control system of the processing machine 01 in such a way that coordinated open-loop and/or closed-loop control of the drives of multiple or all units 100; 300; 600; 700; 900; 1000 of the processing machine 01 is and/or can be carried out. Accordingly, the individual units 100; 300; 600; 700; 900; 1000 and/or in particular modules 100; 300; 600; 700; 900; 1000 of the processing machine 01 can be and/or are operated preferably electronically synchronized with one another, at least with respect to their drives, in particular by means of at least one electronic master axis. For this purpose, an electronic master axis is preferably specified, for example by a higher-level machine control system of the processing machine 01. As an alternative or in addition, the individual units 100; 300; 600; 700; 900; 1000 of the processing machine 01 are and/or can be mechanically synchronized with one another, for example, at least with respect to their drives. Preferably, however, the individual units 100; 300; 600; 700; 900; 1000 of the processing machine 01 are mechanically decoupled from one another, at least with respect to their drives.

A substantially flat section of the transport path provided for the transport of sheets 02 in this context shall be understood to mean a section that has a minimum radius of curvature of at least 2 meters, more preferably at least 5 meters, and still more preferably at least 10 meters, and still more preferably at least 50 meters. A completely flat section has an infinitely large radius of curvature and is thus likewise substantially flat and therefore likewise has a minimum radius of curvature of at least 2 meters. Unless described otherwise, each of the units 100; 300; 600; 700; 900; 1000 of the processing machine 01 is preferably characterized in that the section of the transport path provided for the transport of sheets 02, which is defined by the respective unit 100; 300; 600; 700; 900; 1000, extends at least substantially horizontally, and more preferably exclusively horizontally. This transport path preferably extends in a direction T, in particular in the transport direction T. A substantially horizontal transport path provided for the transport of sheets 02 means, in particular, that within the entire area of the particular unit 100; 300; 600; 700; 900; 1000, the provided transport path only has one or more directions that deviate by no more than 30°, preferably no more than 15°, and more preferably no more than 5° from at least one horizontal direction. The direction of the transport path, in particular the transport direction T, is in particular the direction in which the sheets 02 are transported at the point at which the direction is measured. The transport path provided for the transport of sheets 02 preferably begins at the point where the sheets 02 are removed from a feeder pile 104.
The processing machine 01 preferably comprises at least one substrate feed device 100, which more preferably is configured as a unit 100, in particular a substrate feed unit 100, and/or as a module 100, in particular a substrate feed module 100.

As an alternative or in addition, the method is preferably characterized in that, in the imbricating process, a respective leading end 31 of a respective sheet 02, in particular succeeding the respective leading sheet 02, is pushed, in particular by means of the at least one sheet transfer means 09, between the trailing end 29 of the respective leading sheet 02 and the at least one sheet infeed means 08, based on the vertical direction V, while the respective leading sheet 02 is still partially held by the at least one sheet decelerating means 07. As a result, the leading sheet 02 does not have to be entirely detached from or halted by the at least one sheet decelerating means 07 when the succeeding sheet 02 is already less than its sheet length away from the rear sheet stop 03.
As an alternative or in addition, the method is preferably characterized in that transport rollers 26 of the at least one sheet infeed means 08 are rotatably driven exclusively by contact of these transport rollers 26 with the respective moving sheet 02, and/or that, as sheets 02 are being transported along the at least one sheet infeed means 08, they slide at least temporarily along at least one sliding surface of the at least one sheet infeed means 08. If, as is preferred, the at least one sheet infeed means 08 is configured as a roller suction system 08 and has passively rotatable transport rollers 26, those transport rollers 26 of the at least one sheet infeed means 08 that are still in contact with the leading sheet 02 can rotate and/or are configured to rotate at a different circumferential speed from those transport rollers 26 of the at least one sheet infeed means 08 that are already in contact with the succeeding sheet 02. Both sheets 02 are nevertheless reliably transported, for example by the vacuum of the at least one sheet infeed means 08.
As an alternative or in addition, the method is preferably characterized in that a movement of the at least one displacement member 12 is preferably carried out by means of a predefined movement profile. At least a portion of the at least one displacement member 12 is preferably guided from above to beneath the reference surface 11, where it occupies the displacement region, which in particular moves along with the at least one displacement member 12. This preferably occurs in such a synchronized way that the at least one displacement member 12 is in contact with approximately the same point on the succeeding sheet 02 for as long as possible. A constant negative acceleration of the leading sheet 02 results in a parabolic curve of the position of the trailing end 29 of the leading sheet 02, based on the transport direction T, over time. The position of the at least one displacement member 12, with respect to the transport direction T, plotted against the time, preferably follows a parabolic curve, at least until shortly before the respective leading end 31 of the succeeding sheet 02 would overtake the at least one displacement member 12. From that point on, the at least one displacement member 12 is preferably moved at a constant speed, based on the transport direction T, which corresponds to the speed of the second sheet 02, and in particular is identical to the transfer speed and/or the processing speed.
As an alternative or in addition, the method is preferably characterized in that, preferably during the displacement process, the displacement region is moved away, by a movement of the at least one displacement member 12, with at least a clearance upstream from the succeeding sheet 02 in the transport direction T, in particular as long as the at least displacement member 12 is at least partially located beneath the reference surface 11 and the succeeding sheet 02 has not yet entered the imbrication gap. The clearance is preferably at least 1 mm, more preferably at least 2 mm, still more preferably at least 5 mm, and still more preferably at least 8 mm. Independently thereof, the clearance is preferably no more than 50 mm, more preferably no more than 20 mm, and still more preferably no more than 12 mm. The smaller the clearance, the more sheets 02 can be processed per unit of time and/or the more gently the sheets 02 can be decelerated, in particular given a predetermined position of the at least one displacement member 12. As an alternative or in addition, the method is preferably characterized in that at least one sheet per second is deposited onto the delivery pile 28 by means of the sheet delivery unit 1000, more preferably at least two sheets 02 per second, still more preferably at least 2.5 sheets 02 per second, still more preferably at least three sheets 02 per second, and still more preferably at least 3.2 sheets 02 per second.
As an alternative or in addition, the method is preferably characterized in that the at least one displacement lever 12 is preferably used as the at least one displacement member 12, which is rotatably arranged about the displacement axis 17. The rotational movement of the at least one displacement lever 12 preferably follows a specified profile such that its position over time with respect to the transport direction T behaves as described above.
As an alternative or in addition, the method is preferably characterized in that the at least one displacement element 12 is configured as a displacement member 12 and, in the displacement process, is moved at least partially to below a transport surface 23 of the at least one sheet infeed means 08. As an alternative or in addition, the method is preferably characterized in that the at least one displacement element 12 is configured as a displacement lever 12 that can be turned, in particular pivoted, and more preferably rotated about a displacement axis 17, and in the displacement process is turned, in particular pivoted and/or rotated, in particular in the direction of rotation D, at least partially about the displacement axis 17 to a point below a transport surface 23 of the at least one sheet infeed means 08. As an alternative or in addition, the method is preferably characterized in that, during the displacement process, the at least one displacement element 12 is situated at least partially below the reference surface 11 of the at least one sheet infeed means 08. As an alternative or in addition, the method is preferably characterized in that a position of the at least one displacement element 12, based on the transport direction T, follows an in particular predefined movement profile as a function of time, at least during the displacement process. As an alternative or in addition, the method is preferably characterized in that the movement profile has at least one parabolic section and at least one linear section.
As an alternative or in addition, the method is preferably characterized in that, in a detachment process, the respective leading sheet 02 is detached entirely from the at least one sheet decelerating means 07, in particular by means of the at least one dropping means 32. The detachment process preferably begins after the displacement process has begun. The detachment process can begin and/or, for example, begins even before the displacement process is completed. As an alternative or in addition, the method is preferably characterized in that, in the detachment process, lowering occurs first at the first connection point 41, after which lowering occurs at a second connection point 42, which, as described, is preferably located downstream from the first connection point 41 based on the transport direction T. Overall, the leading sheet 02 is preferably detached from the upper sheet transport system 06 in that, first, its trailing end 29 is detached from the upper sheet transport system 06, and in particular from the at least one sheet infeed means 08, by means of the at least one displacement element 12, and that, thereafter, a portion of the leading sheet 02 that is located further in the transport direction T is detached from the upper sheet transport system 06, and in particular from the at least one sheet decelerating means 07, by means of the at least one dropping means 32, in particular by means of a part of the at least one dropping means 32 that can be lowered by means of the at least one first dropping drive 33, and that, thereafter, the leading end 29 of the leading sheet 02 that is located even further forward in the transport direction T is then detached from the upper sheet transport system 06, and in particular from the at least one sheet decelerating means 07 by means of the at least one dropping means 32, in particular by means of a part of the at least one dropping means 32 that can be lowered by means of the at least one second dropping drive 34.
As an alternative or in addition, the method is preferably characterized in that, following the detachment process, the at least one sheet decelerating means 07 is accelerated again, in particular to the transfer speed and/or to the processing speed, after which the respective succeeding sheet 02 is brought into contact with the at least one sheet decelerating means 07. The sheet 02 that previously was the succeeding sheet thereby becomes a new leading sheet 02 and the method can be repeated or continued accordingly.
As an alternative or in addition, the method is preferably characterized in that, in a stacking process, the respective sheet 02 that has just been detached is deposited downwardly from the at least one sheet decelerating means 07 onto a delivery pile 28. The delivery pile 28 is thereby increased by this leading sheet 02. The delivery pile 28 is preferably formed between the at least one forward pile limiter 04 and the at least one rear sheet stop 03. The at least one rear sheet stop 03 is preferably adjustable in terms of its position with respect to the transport direction T along a format adjustment path. In this way, adjustments can be made and/or, for example, are made to different sheet lengths, in particular a one-time adjustment in the event of a format change. The at least one rear sheet stop 03 establishes a rear boundary of the delivery pile 28. A forward boundary of the delivery pile 28 is preferably established by the at least one forward pile limiter 04. The at least one forward pile limiter 04 is preferably movable, in particular periodically movable, with respect to the transport direction T along a pile forming path. In this way, the delivery pile 28 can be brought into shape and/or, for example, is brought into shape, in particular by pushing respective sheets 02 in the transport direction T so as to yield uniform forward and/or rear boundaries of the delivery pile 28. Periodic movements of the at least one forward pile limiter 04 are preferably carried out multiple times during operation of the sheet processing machine 01, for example multiple times per minute. Lateral pile limiters are also provided, for example. The lateral pile limiters are preferably adjustable, based on the sheet format, in terms of their position based on the transverse direction A, and/or in particular are periodically movable with respect to the transverse direction A, in order to bring at least one lateral boundary surface of the delivery pile 28 into shape.
While preferred embodiments of a sheet processing machine, a method for inspecting at least one remaining portion of at least one sheet processed by a shaping machine and a method for inspecting a sheet, all in accordance with the present invention, have been set forth fully and completely hereinabove, it will be apparent to one of skill in the art, that various changes could be made thereto, without departing from the true spirit and scope of the present invention, which is accordingly to be limited only by the appended claims.
