This application is the U.S. national phase, under 35 USC 371, of PCT/DE2003/003972, filed Dec. 3, 2003; published as WO 2004/056686 A1 on Jul. 8, 2004 and claiming priority to DE 102 59 681.6, filed Dec. 18, 2002 and to DE 103 13 774.2 filed Mar. 27, 2003, the disclosures of which are expressly incorporated herein by reference.
The present invention is directed to devices for processing and/or conveying a web, as well as to methods for their regulation. At least one web processing tool is movable by an actuating member transversely to a running direction of the web of material.
A device for longitudinally cutting foils and tapes is known from EP 1 238 935 A2. An upper cutter can be positioned transversely to the transport direction of the web for setting a cutting width.
A roll changer is known from DE 101 50 810 A1. Two roll arms form a pair of arms for receiving a roll, each of which arms can be individually moved by its own motor along an axis of rotation of the roll.
DE 196 02 248 A1 discloses a former. For the lateral control of the folded continuous web, the former can be moved along an inlet gap between two downstream located rollers.
A turning bar, which can be positioned transversely to the incoming direction of the web, and a register roller, which can be positioned along the incoming direction of the web, are known from WO 01/70608. The turning bar is pivotable in such a way that it provides directional changes toward either the right or the left, depending on its position.
DE 36 14 981 C2 discloses two web edge sensors, each of which has a drive mechanism. Both drive mechanisms are controlled by a common control device. DE 35 33 274 C3 discloses a similar device.
A transport device with two side-by-side arranged conveying devices for endless material, is shown in DE 195 40 164 C1. Each device has an axially movable advancement arrangement.
An arrangement, by the use of which it is possible to cut two partial webs or three partial webs of variable width out of a running paper web of maximum width and to fold these partial webs, is known from DE 42 04 254 A1. The arrangement disclosed there includes three formers which are arranged at two levels. Two formers, which adjoin each other at a first level, are arranged to be displaceable transversely to the running direction of the paper web in order to be selectively used for folding both partial webs of a paper web which was divided into two partial webs, or for folding the two outer partial webs of a paper web which divided into three partial webs. A matching of other web-conducting devices, except for the formers, to the respective web width is not provided.
A turning bar arrangement is known from DE 43 11 437 A1. Turning bars can be shifted to displace a web, which has been turned by them over its width, toward the left or the right, depending on the position of the turning bars. This turning bar arrangement cannot be easily combined with the arrangement of DE 42 04 254 A1, since a partial web divided into three and which is displaced by half a web width, does not meet the former for which it is destined.
DE 100 03 026 C1 discloses a device for processing a web, and having at least one former and a cutter arranged upstream of it. The cutter and the former can be moved transversely to the running direction of the web by a common actuating member.
Web processing elements or web guide elements, which are embodied as turning bars, as longitudinal cutters and as a registration roller are disclosed in U.S. Pat. No. 3,734,487. These elements can be prepositioned by individual drive mechanisms with regard to a planned production run.
EP 0 457 304 A1 relates to a mechanism of a device for folding pockets. It includes two processing elements which can be moved in opposite directions by a common drive mechanism.
The object of the present invention is directed to providing devices for processing and/or for conveying a web, as well as methods for their regulation.
In accordance with the present invention, this object is attained by the provision of a device for either processing or conveying a web in a machine which works with the web. At least one web processing tool is embodied as a former, or as a cutter that is arranged on the web travel path before the former. The cutter and the former are movable by at least one actuating member transversely to a running direction of the web of material. A turning bar unit is arranged upstream of the former. The turning bar is movable transversely to the web running direction by an independent drive mechanism. The drive mechanisms for the former and the turning bar are in connection with a common control device.
A substantial advantage to be obtained by the present device or by use of the present method rests, on the one hand, in that an extensive setting, at the time of the start of the production, is omitted. In contrast to settings taking place at the start of printing, and by the use of control circuits, the amount of waste can be reduced.
A particular advantage of the present invention is that it makes possible a rapid adaptation of the web processing device to a change of the web widths to be processed. A user of the device does not have to gain individual access to every web processing tool which must be displaced for adaptation to the web width.
Further time savings result if the control unit itself is configured to automatically calculate, and to set the positions of the various processing tools which are required to be correlated with each other, from a small number of input parameters. In the simplest case, it suffices, for the calculation of these positions, to merely preset the width of a web to be processed. From this preset information, the control unit can determine the required position of all of the web processing tools in a simple way with one provision. For example, regardless of their widths, a reference line of all of the webs to be processed, such as, for example, a right edge or a left edge, or preferably the center line, takes up the same position.
Since the displacements of some web processing tools, which are required for adaptation to a changed web width, are fixedly correlated, the device, in accordance with the present invention, can be simplified. One actuating member can be used for simultaneously displacing several web processing tools.
A former is a part of the web processing tools of the device in accordance with the present invention. With a suitable selection of the reference line, it may be sufficient if only one of two formers is to be displaced. However, if the center line of the web to be processed is selected as the reference line, which selection is preferable, at least both side-by-side arranged formers must be displaceable.
To generate several partial webs from a single initial web in the device in accordance with the present invention, each of which partial webs then can be fed to individual formers, the device in accordance with the present invention usefully has at least one cutter for use in longitudinally cutting the initial web into partial webs. If more than one such cutter exists, at least one of them must be displaceable.
Furthermore, a device can have at least one interval cutter for the longitudinal cutting of the web of material into pages. If the web of material is a printed paper web, and in particular is a newspaper, such an interval cutter can be employed for cutting the web locally at the height of every respective second page. This can be done in order to produce, for example, a broadsheet signature with a tabloid insert.
It is also of advantage if the device of the present invention has a longitudinal cutting arrangement with at least one cutter, which is also preset transversely to the running direction of the web. This is advantageous in order to fix the cutting line for the partial webs to be created.
If an initial web, which is cut into several partial webs, is being processed in the device, traction or interceptor rollers, provided as web processing tools, are usefully assigned to each partial web in the same way. It is therefore desirable that such rollers are also automatically positionable by the control unit in accordance with the width of the initial web to be processed and the number of partial webs into which the web is longitudinally cut.
Turning bars can also be provided as processing tools, which turning bars can be displaced by the use of the control unit. Also, here, and in the discussion which follows, web conducting devices, web drive mechanisms and/or web guidance devices such as, for example, turning bars, contact pressure rollers and/or guide rollers, are also understood to be processing tools.
To drive the displacement movement of the processing tools, the actuating members preferably each have a threaded spindle. The displaceable processing tools each have a sliding block, which block is in engagement with such a threaded spindle.
The threaded spindle can advantageously have several sections which differ in their thread direction of rotation and/or gradient. The sliding blocks of several processing tools of the same type can each be in engagement with the different sections of an identical spindle in order to displace the processing tools in a coupled manner. However, such displacement may be in different directions and/or at different speeds, as required.
Preferred embodiments of the present invention are represented in the drawings and will be described in greater detail in what follows.
Shown are in:

b, displaceable formers, set for a narrow paper web, in

A former arrangement of a web processing machine is represented in
A frame 15 or a stand 15, which is connected with the left former 06, is simultaneously used as a support for a bearing of the roller 03. The roller 03 accordingly follows each movement of the former 06. The right side of the roller 03 is telescopically displaceable on a journal which is fixed on the frame 04, such as, for example, by the use of an axially displaceable bearing 25, as shown in
An interval cutter 05, or a skip slitter 05, is also rigidly connected with the former 06, such as, for example, via the stand 15, and is mounted above the roller 03. The interval cutter 05 has a rotating, intermittent cutting edge, which edge is aligned with the fold line of the former 06 and which alternatingly respectively cuts one pair of a pair of printed pages alternatingly imprinted on the partial paper web 01, and leaves the other one uncut. If the uncut pairs of sides are sides of broadsheets, with lines oriented transversely with respect to the conveying direction, and the cut pairs are tabloid pages, whose lines are oriented in the conveying direction, it is possible, in a simple manner, to produce a signature with an insert of half a page size from the partial paper web 01 in a connected folding apparatus, which is not specifically represented.
The setting of the formers 06, 07 for use in processing two partial paper webs 12, 13, which with respect to the partial paper webs 01, 02 of
In an advantageous variation, or a further development of the present invention, a driven roller 30, which is arranged downstream of the former tip with the former 06, 07 in addition to, or in place of the cutter 05, is laterally movable together with, or at the same time as, the former 06, 07. To this end, the former 06, 07 is preferably connected with a support for, or a seating of the roller 30, preferably by the use of a common stand 15. In the course of displacing the former 06, 07, the roller 30 is thus simultaneously moved. The roller 30 may be embodied as a driven transfer roller 30, over which a continuous web, which is leaving the former 06, 07, is conducted and which thus undergoes a directional change. In another embodiment, the roller 30 can be configured as a traction roller 30 of a traction roller group and can be, for example, individually motor-driven, and against which a contact pressure roller 35 can be placed. In this case, the entire traction group 30, 35 is connected with the former 06, 07.
A former arrangement, of the type represented in
In an advantageous embodiment of the present invention, it has been provided, for the pre-setting the printing press, as seen in
a shows an interceptor roller arrangement as a further example of a web processing tool in a device in accordance with the present invention. This interceptor roller arrangement consists of a roller 14, around which a paper web, which is not specifically represented in the drawing, and which is to be intercepted, is wrapped during production. The arrangement also includes several rollers 16, several sliding blocks 18, 19, 21, a guide rail 17, a threaded spindle 22 and an electric motor 23, which is controlled by the previously described control unit 10, or the system S.
The roller 14 is rotatably seated in the frame 04. The guide rail 17 is seated in the frame 04 and is parallel with the roller 14. Several of the sliding blocks 18, 19 are displaceably arranged on the guide rail 17. A sliding block 21, which is arranged so as to be centered with respect to the roller 14, is fixedly arranged on the guide rail 17. Each of the sliding blocks 18, 19 and 21 supports a rotatably mounted roller 16. In this depicted configuration, the rollers 16 press against the roller 14 and roll off on it. Since the rollers 16 are intended to be rotatable in only one direction, they prevent a return movement of the paper web which is wrapped around the roller 14 in case of a possible paper web break.
The threaded spindle 22 passes through the frame 04, on one side of the frame 04, and projects from the frame 04 at this point. In this case, the threaded spindle 22 is aligned parallel to the roller 14 and to the guide rail 17. The threaded spindle 22 has two different threaded sections, with threads which turn in different directions, and which threads are separated from each other by a section without a thread. The sliding block 21 is arranged on the threaded spindle 22 in this threadless section. The two threaded sections have thread gradients which increase along a longitudinal axis of the threaded spindle 22 proportionally to their distance from the fixed sliding block 21. The sliding blocks 18, 19 are themselves not in engagement with the left or right threaded section, as viewed from the sliding block 21, by an interior thread with several turns. Such an engagement would become stuck because of the variability of the thread gradient of the threaded spindle. Instead, each sliding block 18, 19 is provided with a single narrow pin which engages the thread of the threaded spindle 22 and which pin is located on a small circumferential section of the respective sliding block 18, 19. The electric motor 23 engages the threaded spindle 22 at the end section of the threaded spindle 22 that is projecting from the frame 04.
If the interceptor roller depicted in
It is also within the scope of the present invention to provide two threaded sections, each with a thread gradient which remains the same over each section's length. This is sufficient for a roller arrangement with no more than three different rollers 16. In the case of a larger number of rollers, as represented in
Another option in accordance with the present invention would be to provide each individual one of the four sliding blocks 18, 19 with its own threaded section of the threaded spindle 22, with each section being provided with a specific gradient. However, in that case, the variability of the web widths to which the interceptor roller can be set is restricted in that the sliding blocks, or at least those which are coupled to the spindle by an interior thread with several turns, could not leave the threaded section having the specific thread gradient suitable to their thread.
It is also possible to provide several threaded spindles, each with two sections of opposite, identical gradients, each of which spindles supports sliding blocks of rollers which are located opposite each other in a mirror-reversed manner, in relation to the center line M. For practical purposes, these several threaded spindles are identical to each other. To achieve different displacements of the rollers coupled with them, the several threaded spindles can be driven by a common electric motor via a gear with a respectively matched transmission ratio. Alternatively, each threaded spindle can have its own electric motor, which is respectively individually triggered by the control unit according to the required displacement.
In the above-described manner, it is also possible to configure traction roller arrangements in a manner which can be set for paper webs of different widths to be processed. This is because traction roller arrangements in principle have a structure to that of interceptor roller arrangements. Such presetting values can be stored in tables for the different production runs. Alternatively a calculation can take place in the system S on the basis of the use from the web widths and the lateral offset to be obtained.
a shows a detailed depiction of a longitudinal cutting arrangement 71 of a superstructure 67, as seen generally in
If the above-described longitudinal cutting arrangement is intended to be used to cut a paper web 36 of narrow width into four partial webs, the threaded spindle 33 is rotated by the electric motor 34, to position the carriages 27 as shown in
The operation of the spindle drive motor 34 is controlled, or is preset, by the control unit 10, or by the system S, which calculates the position of the cutters 28 by the use of a width of the web to be cut, as set by the user, or which width is automatically detected by sensors which are not specifically represented, or of the partial webs resulting from the cutting.
In the case of several cutter units, such as pairs of cutters 28, 32 and counter-cutter 29, it is possible, for example, to drive them all separately, and/or to bring them into and out of contact individually.
The axial positioning or at least the pre-setting of the printing press control is preferably performed automatically on the basis of the width of the web intended for being imprinted and of the cutting lines to be made specifically with respect to the product, or is performed manually from an operating console. To this end, a check is made, for example prior to production start, by the system S, from the printing press control or from an appropriate software program, regarding the actual setting with respect to pre-setting values that are required for the planned production, and/or a pre-setting, by acting on the drive mechanism 34, or the drive mechanisms 34 is performed. Such presetting values can be stored in tables for the different production runs, or a calculation can take place in the system S on the basis of the use from the web widths and from the lateral offset to be obtained.
A turning-bar deck, with two crossed turning bars 37, 38, is represented in
A reversing roller 47 is rotatably arranged in the frame 04 between the guide rail pairs 39 and 41 and extends transversely in respect to them.
A paper web 51, which enters perpendicularly, with respect to the guide rail pairs 39 and 41, runs around the oblique first turning bar 37 and thereby changes its travel direction by 90°. Web 51 then loops around the reversing roller 47 and runs from there back again and over the obliquely placed second turning bar 38, which is crossed by the first turning bar 37. The web's running direction is again changed by 90°, so that after leaving the turning bar deck web 51 has regained its original running direction, but has been offset by exactly one paper web width and has been inverted.
A pair of threaded spindles 48, which are parallel with the guide rails 39, 41, and of which pair, a lower threaded spindle 48 is hidden by the upper threaded spindle 48 in the drawing figure, is rotatably seated in the frame 04. A drive mechanism 49, such as, for example, an electric motor 49, acts on an end section of each spindle 48.
If the above-described arrangement is to be employed for a paper web 52 of a lesser width, as shown in
The above-described turning bar deck is represented in
A paper web 53, which is to be offset, enters the turning bar deck perpendicularly with respect to the guide rail pairs 39 and 41, successively loops around the first turning bar 37 and the second turning bar 38, and leaves the turning bar deck, laterally offset by one paper web width, and without having been inverted.
In a manner the same as was the case of
A turning bar arrangement of a printing press, as depicted in
In advantageous embodiments of the present invention all of the turning bars 37, 38 are configured to be pivotable or to be able to be tipped by 90° in respect to the level of the respective incoming web. In a variation of the structures depicted in
As discussed shown above, in a preferred embodiment of the present invention, every turning bar 37, 38 is, as a whole, arranged in the superstructure 67 to be movable in a direction transversely to the direction of the incoming web. By this movement, the turning bar 37, 38 can be positioned, by use of the drive mechanism 49, so that it is matched to a product, or to a web path, or to a web width.
In an advantageous manner, for presetting the printing press, the drive mechanisms 49 of the turning bars 37, 38 are in a signal connection with the system S. On the basis of production data, such as, for example, the intended web path, resultant theoretical cutting line, and/or width of the web or partial web, the actual position of the turning bar 37, 38 is compared with a position which has been or which can be preset for this production run and, as may be required, an appropriate movement of the turning bars 37, 38 is initiated via actuating commands to the drive mechanisms 49 involved. Such presetting values can be stored in tables for the different production runs. Alternatively a calculation takes place in the system S on the basis of the use, from the web widths and the lateral offset to be obtained.
In a further development of the superstructure 67, a drive mechanism, which is not represented, for use in pivoting, is assigned to the pivotable turning bars 37, 38 which, for example in a manner which is the same as was previously explained in connection with the drive mechanisms 49, is preset by the above-mentioned system S in accordance with the planned production and/or web guidance. Advantageously, such a drive mechanism is, for example, embodied as a cylinder, which can be charged with a pressure medium, which cylinder is engaged, on the one side, with the frame, and, is engaged on the other side, with the turning bar 37, 38 outside of its pivot point.
To preset the printing press, it has been provided, in an advantageous embodiment, that a drive mechanism, which is not specifically represented, and which is used for driving the described movement of the former 06, 07, is in a signal connection with a control 10, or advantageously with the system S. The actual position of the former 06, 07 is compared by the use of production data, such as, for example, by the width of the web or partial web with a position which is or which can be preset for this production. If required, an appropriate movement is initiated by the use of actuating commands to the drive mechanism involved. The former 06, 07, or the former tip must be appropriately positioned, based on the width of the web, the partial web or the continuous web. For example, the former 06, 07 is positioned in such a way that, for each web width, the folded continuous web reaches the folding apparatus 68, or its folding devices, in a suitable manner, such as, for example, centered on the shell face of the following cylinder. Presetting values can be stored in the form of tables for the various production runs, or a calculation takes place in the system on the basis of the web paths resulting from the web widths and the lateral offset.
The above-described web processing tools are, individually or in groups, a component of a machine which works on a web and/or which processes a web, such as, for example, a printing press (
In one embodiment, a varnishing unit 64 can be provided in the web path.
Following imprinting and, if performed, varnishing, the web B runs, for example, through a dryer 65 and, if needed, is cooled again in a cooling unit 66, if the drying in dryer 65 was performed thermally. Downstream of the dryer 65, at least one further conditioning unit, which is not specifically represented in
In an advantageous embodiment of the present invention, the printing press additionally has a separate transverse cutting device 69, such as, for example, a so-called planographic delivery device 69, in which a web B which, for example, had not been conducted through the folding apparatus 68, is cut into format sheets and, if required, is stacked or delivered.
Preferably, the system S, which is used for presetting the processing tools or units, is assigned to the printing press, such as, for example, as an additional program in a printing press control device and/or a planning system, which control device or system is in a logical signal connection with one or with several of the above mentioned processing tools, or units 61, 62, 63, 64, 65, 66, 67, 68, 69, and in particular with the units 61, 63, 67.
In an advantageous further development of the present invention, the elements of the roll changer 61 also fall under the above mentioned processing tools. For example, it is also advantageous, in case of production changes by one or by several of the above mentioned web processing tools, to simultaneously perform a lateral displacement of the roll arms for matching the new width and/or position of the web. The displacement of the roll is useful, for example, if a partial web is intended to be moved through the printing press in a different alignment than had previously been done.
It is also advantageous if a lateral adjustment of cutting register and/or color register measurement members, such as, for example, sensors, and/or a web edge regulation device 57, are simultaneously matched to the new production run in the axial direction. It is further advantageous if an adjustment of the contact pressure rollers against the traction roller underneath the former takes place.
In the area of the folding apparatus, an adjustment of the paddle wheel in the outlet, an adjustment of the gluing nozzles of a possibly provided gluing unit, an adjustment of the second longitudinal fold, and/or an adjustment of the perforating cutter for longitudinal perforation, can take place simultaneously, for example, for different adjustments.
In the above context, in the wider sense, the term web processing tools is also understood to include sensing and actuating devices, which have an effect on the detection and on the influencing of the running of a web, or partial web, or continuous web.
When presetting the printing press, such as, for example, at the start of a production run, the system S receives data that is relevant to the planned production run from a product planning system, from a print preparation stage, from the printing press operator himself, and/or from an existing imposition pattern for use in presetting. The imposition pattern contains the paths of the webs or of the partial webs which are intended for the planned production run, as well as the provision of the forme cylinders with the print pages, as well as the ink colors of the different printing groups. Information regarding the web width and/or the intended lateral position of the web can then be entered by the printing press operator, or can be obtained from a machine control device, the roll changer 61 itself, a logistics system, or from a product planning system.
To position the longitudinal cutting arrangement 71 and/or the roll changer 61, the information regarding the planned web width and/or the web position, for example, is used to position the former 06, 07 for the partial web width. The information regarding the intended paths of the web, or the partial webs, is processed for positioning the turning bars 37, 38 and, if required, for also positioning a linear registration device 58 that is assigned to the partial web in the superstructure 67. In a further development, it is possible to perform the presetting of colorimeters in the printing groups, for example, by using data from the print preparation and/or the imposition pattern, such as color densities, deployment, etc.
In an advantageous first variation of the simplest preferred embodiment of the printing press in accordance with the present invention, at least the longitudinal cutting arrangement 71 with regard to the web to be processed, is preset by the system S. In this case, the roll changer 61 can, if desired without “external” presetting, always be regulated to the center by its own inner control circuit. In a further development, in this process the former 06, 07, or the former unit 73, are also positioned, laterally and/or in the paper running direction by the system S.
In a second variation of the printing press in accordance with the present invention, at least the positioning, laterally and/or in the paper running direction, of the former 06, 07, or of the former unit 73, is preset by the system S or by the control device 10. It is then possible to position, together with the former 06, 07, a cutter 05 and/or a downstream arranged driven shaft 30 and to connect them with the former. In this case, the roll changer can, again if desired without “external” presetting, always be regulated to the center by use of its own inner control circuit.
In a well-appointed embodiment of the present invention, presetting, for positioning the former 08, 07 and the turning bar unit 72, as well as possibly also the roll changer 61, is performed by the system S.
In an alternative embodiment, presetting of the longitudinal cutting arrangement 71, or at least one cutter 28, 32, and of the turning bar unit 72, as well as possibly also of the roll changer 61, is performed by the system S. In a greatly automated embodiment, the former 06, 07 is also positioned.
In addition to the above-mentioned three enlargement stages, presetting of the calorimeters and/or of the stripper elements can also advantageously take place by use of the system S.
Basically, depending on the need and the degree of automation, a selection of units or of partial units which are to be preset and which differ from what was mentioned above, can be provided. Thus, for example, presetting can be directed in one embodiment only to setting the calorimeters and the longitudinal cutting arrangement 71. In another embodiment, all of the units or the partial units which are provided for web guidance and for cutting, and in particular those of the superstructure 67, can be intended for presetting.
In addition to the above mentioned enlargement stages and their variations, it is advantageously possible to perform presetting of cutting register and/or of color registration measurement members 56, such as, for example, sensors, and/or a web edge regulation device 57, in the axial direction, in view of a new production run, and/or an adjustment of the contact pressure roller 35 or rollers against the traction roller 30 in response to an expected thickness of the continuous web underneath the former 06, 07.
The drive mechanisms 11, 23, 34, 49 of the above-mentioned processing tools, or at least those of the processing tools intended for presetting, are preferably structured to be remote-controlled, or are remote-controlled by the system S or by the control device 10. In contrast to actuating members which are operated manually or which can be operated only at the position, presetting is possible, in this way, in one or in several of the previously mentioned embodiments, and variations thereof, in an easy and rapid manner via the system S or via the control console.
The system S can be embodied as a control unit S, which includes a user interface for input and/or an interface for reading-in, from the printing press control device, from a production system and/or from a print preparation stage, of at least a width and/or a web path of a web to be processed. A computer, for use in determining a desired position of the units, partial units or processing tools to be preset, such as the roll changer 61, the longitudinal cutting arrangement 71, the turning bar 37, 38, a linear registration device 58 assigned to the partial web, and/or the formers 06, 07, on the basis of the web width is also part of the system S. Also included are drivers for triggering the associated actuating members for setting the respectively determined desired position.
While preferred embodiments of a device for transmitting and conveying a strip of material and methods for regulating these devices, 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 in, for example, the specific structure of the printing units, roll changers and the like could be made without departing from the true spirit and scope of the present invention which is accordingly to be limited only by the following claims.
