It is in a synchronized movement phase the modules a position P (Fig. 1) as a transfer position reached. This transfer position P of the substrate 2 towards the gripper 9, 9 'of the processing roller 4 is both through a register adjustment in the area of upstream sheet printing machine as well as a corresponding Adjustment of the grippers 14 of the feed device 13 optimally adjustable. With this register adjustment in the area of the printing press is an adjustment of the Grippers 9, 9 'in the area of the roller 4 can be dispensed with, so that on the device 1 does not affect its stability Control elements are required.

Of functional importance for the accuracy of the finishing process in the device 1 is an exact setting the gripper 9, 9 'and the gripper 14 to each other. The grippers 14 of the feed device 13 pass through Transfer area (at P) to the movement path D of the Gripper 9, 9 'of the processing roller 4 so approximate movement path E that in the handover and takeover in the area P the substrate in phases simultaneously from the gripper 14 of the feed unit 13 and the gripper 9 or 9 'of the processing roller 4 is held. In the area of the transfer position P act the grippers 9 and 14 on a transfer path of for example 1 to 5 mm together, this way can be adjusted in register to a dimension of ± 0.01 mm.

The illustration according to FIG. 2 clarifies that the feed unit 13 in the area of your sheetfed press (not shown) facing end with a painting and / or Dryer unit 15, 16 is provided for the substrates.

On the other hand, the device 1 is the one being processed Laying device 18 taking over substrate 2, in the area of which after a punching process as Processing waste 19 designated part of the sheet 3 (Fig. 5) receiving, designated 20 in total is arranged (Fig. 1). It is planned a shredding device 24 into the respective waste parts 19 via conveyor pipes 25, for example in a Fall direction R, fed and then via pipes 25 'in a bunker 26 can be derived. It is also conceivable that Delivery pipes 25, 25 'to a central disposal unit (not shown) to connect.

The shredding device provided as a disposal device 24 acts across a building ceiling 30 Conveyor pipe 25 together with the device 1, these in the vicinity of the processing rollers 4, 5 facing end 21 connected to the delivery device 18 is. The delivery device 18 advantageously has a vacuum cup 22 (Fig. 4) with which a separation of the substrate 2 and the waste parts 19 (Fig. 5) reached becomes. The laying device is in a practical embodiment 18 provided with a table 23, the top of the Receives substrates 2 (Fig. 5, right side) and transported away. At its receiving end 21, the Table 23 together with the lower processing roller 4 a passage gap 28, in the area of a downward directional passage (arrow F) of through processing generated waste 19 to the shredding device 24 is achieved in that it is still firmly in the gripper 9th held waste part 19 taken in the direction of arrow F. is and at F 'in the delivery pipe 25 (Fig. 2). At the discharge end of the working gap 6 that is as a good part remaining substrate 2 via a spread separated from the waste part 19, the substrate 2 for example on a dash-dot line in FIG. 4 illustrated web 27 reaches the table 23. This Spreading and transport can advantageously be supported be that over a not shown Device a blowing or suction air flow on the substrate 2 or the waste part 19 is directed.

The enlarged individual representation according to FIG. 4 illustrates that the at least one gripper 9, 9 'of the processing roller 4 with a respective circumferential register adjustment device 31 is provided, by means of which the grippers 9, 9 ' by a pivoting movement (arrow S, Fig. 4) and precisely fitted around the central longitudinal axis M of the roller 4 can be.

In addition to this adjustment option S, an adjustment option can be used the processing roller carrying the gripper 9 4 can be provided, this one not shown Side and / or diagonal register adjustment devices having. An adjustment according to Arrows H and K are executed (arrow H: diagonal register; Arrow K: side register). It is also conceivable that both processing rollers 4 and 5 the above-described register adjustments S, H and K.

For flexible use of the device described above 1 are the processing rollers 4, 5 in the area of Tool parts 7, 8 with interchangeable machining tools Mistake. For their quick replacement can the processing rollers 4, 5 advantageously from each Magnetic cylinders are formed on which the machining tools 7, 8 in the form of punching, creasing, punching and / or Embossing tools are set.

It is also conceivable that one of the processing stages described above, in particular a perforation of the substrate 2, integrated on the processing line in accordance with the register Additional device (not shown) realized is, this in front of or behind the device 1 in the processing sequence is provided.

The overall concept of the device 1 also provides that the processing rollers 4 and 5 individually, as a whole or can be replaced together (arrow L, Fig. 1, Fig. 6). The embodiment of the device 1 according to FIG. 2 shows an arrangement of a counter pressure roller 35 in the area the processing roller 4 is arranged. The processing rollers 4, 5 or the counter-pressure roller 35 can after Kind of a cassette so integrated into a machine frame 40 be that in a transverse direction L '(Fig. 3) the individual or joint removal is possible and thus the respective Machining tools 7, 8 or the entire punching cassette or the punching tools are particularly easy to replace are.

6 is in a second embodiment the device 1 'as one independent of the register an associated printing machine 32 effective unit illustrates, from the printing press 32nd removed substrate 2 by means of a conveying process, fed for example by a conveyor belt 33 from a register roller 34 detected, in register between the two processing rollers 4, 5 inserted and then with the delivery unit 18 of a further finishing and / or Stacking unit 36 is fed. It is conceivable also that this off-line unit with painting and / or Dryer assemblies similar to units 15, 16 in FIG. 6 is equipped.

The device 1 for punching printed substrates is in a known version with a Machining rolls 4, 5 supporting machine frame 40 provided that in the area of bearings 44, 45 for the processing rollers 4, 5 side stands with a heating and / or cooling device 43 is provided (Fig. 2, Fig. 3). This heating and / or cooling device 43 will with a temperature in the area of the side stand 41, 42 detecting control unit 46 connected so that with this Device combination the machining conditions in the working gap 6 can be influenced between the processing rollers 4, 5 are constant and the center distance between M and M ' is held.

The use of the control device 46 is particularly for an optimization of the cutting conditions during use of carbide knives provided as cutting tool parts 7, 8. It has been shown that by a constant Temperature of the side stand 41, 42 in the area of their bearings 44, 45 which are optimal for the respective substrate 3 distances of the tool parts set to the working gap 6 7, 8 also over a long processing time remain constant and thus with high processing quality a significant reduction in tool wear, in particular on hard metal knives. As well is intended to increase tool wear by increasing the temperature compensate. For example, a change in distance due to a temperature increase of 1 ° C of 0.001 mm, for example the center distance and / or be set.

For this optimization of working conditions can already the use of a heating cartridge as a controllable heating device be sufficient so that with little technical Effort to improve the cutting, punching or embossing conditions is reached in working gap 6. By a Appropriate temperature detection can be done with a Control unit provided comparator deviations from the optimum detected and heating up with a short reaction time (or cooling) in the area of the heating cartridge be that the constant temperature conditions in the range the side stand 41, 42 for the optimal machining process to care. It is also conceivable that in addition to a corresponding coolant to and from the heating device laxative cooling device (not shown) in the area the side stand 41, 42 is provided, with the possible variations when adapting or making targeted changes the temperature is still expandable.

In Fig. 7, a, b and c, the processing rollers 4, 5 of the device 1 in one Shown top view. With these representations the Cutting line formation in a rolling punching process of the substrate 2 fed in a feed direction A. clarifies, with only a dashed line Stamping contour S illustrated on the upper processing roller 5 becomes. In the illustration according to FIG. 7a, the Axes M and M 'of the two rollers 4 and 5 in a vertical Level on top of each other. The punch contour S (for example from a punching plate on the processing roller 5 formed) arrives at the initiation of a rotary movement D ' Roller 5 and a corresponding counter-rotating movement D (Fig. 2) of the processing roller 4 in the processing nip, so that in this phase shown The punching process for a punching line 50 begins at a point 51.

The substrate is moved horizontally around the feed path T moves further, so that the cutting line 52nd is generated up to the end point 53. This cutting line 52 as a result of the punching process, however, faces the vertical plane with the two axes M and M 'an inclination (Angle W).

This oblique course of cut lines is for one Variety of punching operations are undesirable and therefore provided by an adjustability in the area of the processing rollers 4 and / or 5 a presetting in this way make that with respect to the feed direction A right-angled and / or parallel cutting lines can be generated are.

In Fig. 7b is to create a right angle cut the upper processing roller 5 with the punching contour S. inclined the angle W '. Starting at the starting point 51 'of the sectional image S with this construction parallel to the axis M of the lower processing tool 4 running punching line 52 'generated. Even in the feed direction A extending punch line 54 (Fig. 7c) becomes vertical to the punching line 52 ', so that with this Inclination of the processing roller 5 is a right angle Contour S can be punched out of the substrate. This angularly accurate execution of the punching contour is in particular required if in the direction of the grain (corresponds to the feed direction A) the substrate 2 extending cuts are provided for subsequent processing and this can therefore be carried out with high precision.

In Fig. 8 is a possibility of constructively changed Parts of the system shown with a rolling Cutting with rotary punching can be achieved. at this procedure is particularly important when punching of cross lines reduced load peaks so that a Machining with low punching pressure is done so frequent adjustment of the tools is avoided and For the first time, slimmer punch cylinders (rolls 4, 5) were also used can be. These components show Diameter to width ratio of 1: 1 or less as 1: 1, for example 1: 1.2; 1: 1.4 and so on. This Size relationships in the area of the processing rollers 4, 5 allow an optimal combination of such devices with conventional printing presses, for example Sheetfed offset presses, the inclination and thus achieved lower punching pressure is particularly advantageous are effective. The processing rollers can thus in their Format (circumference x width) should be dimensioned so that this is the same as the format of the image-bearing printing cylinders.

The feed unit 13 feeds the substrate from the printing press 32 in the area of the processing rollers 4, 5, such as this is already shown in more detail in FIGS. 2 and 6. For the transfer of the substrate in area P is the gripper bar 9 provided in the embodiment according to FIG. 8 with a helix angle 69 on the processing roller 4 is mounted in an inclined position. This slant can with an axial tilt (tilt angle 70) in the range a feed roller 71 cooperate so that a rolling Transfer and takeover of the substrate is reached. This comes with a corresponding inclination between the processing rollers 4 and 5 so inserted and transported that a rolling cut achieved without sudden stress on the punching tools can be. With an angle 69 'is an additional one Inclination in the area of the processing roller 5, for example an oblique position of the punching plate, shown, taking care of all of the slopes and tilts a helix angle of 0.5 ° as practical has highlighted.

9 and 10 is a basic concept of a drive concept in the area of the printing machine 32, the feed unit 13 and the punching device 1. there are two servo drive motors 72 and 72 'for securing a synchronous drive with a contactless one Gear connection 73 (Fig. 10) provided, the Gears with a constant even during the drive phase Intermesh distance 74, 74 'without contact. The teeth only come into contact when a control error, for example in the area of software could lead to an undesired overloading of the system and an immediate shutdown of the drive torque is required becomes. With this gear connection 73 is the fuse the system against destruction, in particular the Gripper 9, achieved with little effort.

In Fig. 11, the device 1 '' is opposite to the 1 modified component arrangement behind the processing rollers (4, 5), whereby the device 1 '' in addition to that already in FIGS. 4 and 5 shown punching and breaking out of the substrate also can be used to punch it. During this punching process grips the gripper 9 in the manner described above and Way the substrate and this gripper position is by keep the corresponding machine control until the substrate the processing nip between the two processing rollers 4 and 5 has passed and the intended Cutting lines or the like are introduced into the substrate. In 11 shows a substrate 2 'with a broken line, that works in its full arc length the working gap 6 'has happened and after this processing a handover or takeover described in more detail below he follows.

The gripper bar 9 has during this holding and processing phase that shown in Fig. 11, comprising approximately 180 ° Rotational position reached and now comes together with the substrate in the area of a storage cylinder 55, which in turn is provided with grippers 55 ', for example punched substrate takes over in register. This storage cylinder 55 is part of a delivery device 18 'with which the stamped Substrate as an intermediate product Z to a delivery conveyor belt 57 moved there, placed on it for further transport (Arrow 57 ') and at the end of the line at W for finishing provided. It is also conceivable that the substrate 2 '(line representation) in the device 1' 'already was punched in full length and on one downstream processing unit (not shown) Substrate in waste part 19 and finished part (so-called Benefit) is shared (Fig. 5).

11 is also for Punching and breaking out provided, however, the waste part 19 (FIG. 5) with the gripper 9 holding it is taken to the storage cylinder 55 and by means of whose gripper 55 'reaches the delivery conveyor belt 57. This Delivery conveyor belt 57 is through the machine control changed in its conveyor angle 56 so that a substantially horizontal conveying direction is adjustable 11 with a dashed line is clear. At the End of the delivery conveyor belt 57, the waste 19 from the Disposal device 20 taken over. For one later punching process indicated by the machine control is the conveyor belt 57 with little effort in the inclined Swiveling position (arrow 56).

The device 1 "has the arms 18 and 57 optional assemblies that do not have any displacements open a three-way display of components. In addition to a display of the substrate without a punch or finishing processing can also the punched Intermediate Z or the punched out benefit separate waste are transported on.

The device 1 ″ can be in an expanded version in the area of the processing rollers 4, 5 with a for laser punching provided provided laser processing unit T. his.

12 and 13 is the punching device designated 1 '' ' in an expanded version according to FIG. 3 Design illustrated. The ones in the operating position Processing rollers 4 and 5 are extended in this Device in their center distance (axes M and M ') more precisely adjustable, so that the machining result is improved. In addition to the already in connection with Fig. 3 described adjustable and adjustable parts with a heating or cooling device 43 is in the side stand 41, 42 of the machine frame 40 according to FIG. 12 each at least one expansion body 58 integrated. These expansion bodies 58 are supported in the machine frame 40 so that Generation of different voltage states and thus caused material expansion of the center distance between the Axes M and M 'or the dimension of a machining gap 59 is adjustable. The side view according to FIG. 13 illustrates that the expansion body 58 on the one hand via adjusting screws 60, 60 'on the respective side stand 41 or 42 is supported. On the other hand, 58 are for the expansion body respective support rollers 61, 61 'or 62, 62' receiving bearing stones 63, 63 'provided above the processing roller 5 are arranged.

This system with the expansion bodies 58 above the processing roller 5 acts with respective spring elements in shape of spring assemblies 67, 67 'and 68 arranged in pairs, 68 'together between the two processing rollers reach under the bearing stone 63, 63 'at the level of the machining gap. These spring assemblies are thus between the bearings 44, 45 and 44 ', 45' of the two processing rollers 4 and 5 supported on the side stands 41 and 42 so that the spring assemblies in the power flow of the device 1 '' ' are integrated. During one under sliding friction conditions in camps 44, 45; 44 ', 45' ongoing machining process (Punching or punching) are the spring packs so effective that a stick-slip effect is avoided is. This through a periodic change of movement and effects caused by downtimes unwanted vibrations, with this structure of the Systems with the spring packs are excluded.

With the above-described expansion body 58 is additional to the control unit 46 already shown in FIG. 3 second control unit 64 connected, which in turn with a Temperature sensor 65 and one or more heating cartridges 66 interacts so that a corresponding temperature change in the area of the expansion body 58 a Fine adjustment realized in the area of the machining gap 59 can be. With this temperature change can the machining gap within a setting range of +/- 0.1 mm so variable by, for example, micrometer steps be adjusted that a precision adjustment is reached. For positioning the processing rollers 4, 5 in their operating position to each other, for example after changing the punching plates, the Adjusting screws 60, 60 'a corresponding rough setting, being a permanently installed adjustment aid in the area of the side stand 41, 42 a dial gauge or the like (not shown) is conceivable.

The above-described actuating movement is especially in the Area of the spring assemblies 67, 67 '; 68, 68 'effective. through the expansion body 58 and the support rollers 61, 61 '; 62, 62 ' the parts in the area of the cylinder bearings 44, 45 placed in a bias state so that during the machining operation under the effect of the punching pressure an unwanted Separation of cylinders 4 and 5 avoided is. An important functional requirement for this one Rough delivery or fine delivery using the Expansion body 58 is the formation of the processing rollers 4th and 5 in the area of the bearings 44, 45; 44 ', 45' without the usual bearer ring contacts. These stock parts are unnecessary in that the support rollers 61, 61 '; 62 62 'and the preloaded cylinder bearings in the system of the machine frame are integrated. In addition to the already described upper support rollers 61, 61 '; 62 62 'are also below the lower processing roller 4 respective support rollers 75, 75 'and 76, 76' provided that according to the type of counter-pressure roller 35 (Fig. 3) are effective.

The system described above allows with little effort the fine adjustments in the area of the expansion body 58, so that both an adaptation of the device 1 '' ' different material thicknesses of the substrate 2 as well a compensation of the controlled by the control unit 64 Tool wear possible in the area of the punching tools are. The embodiments of the processing device according to the invention thus form an overall unit that in largely similar configurations also for embossing, Grooves, punching, hologram embossing, numbering or the like can be used is.

FIG. 14 shows a basic illustration of FIG. 8, similar to FIG Punching device 1 with inclined (angle 69, 69 ', 70 according to FIG. 8) roller bodies 4, 5 and 71, with upstream the punching device 1 a second processing module 80 is provided. The punch cylinder pair 4 and 5 as well a pair of cylinders 81 and 82 are each rectangular arranged to the machine longitudinal axis so that a Passage of the substrate in direction A (Fig. 7) reached becomes. 14 on this system Punching plates shown each obliquely on the front and rear punching cylinder pair 81, 82 or 4, 5 clamped, so there is between the respective top and Lower cylinders a rolling cut for the Cross lines. The prerequisite for this is that the substrate or the sheets are in the same inclination as the punching plates be guided through the device.

The advantage of this system is that for the cylinder pairs 4, 5 and 81, 82 provided processing plates can be manufactured in normal geometry and none Reduction of usable punching areas on the substrate arise. When working with full punch cylinders, punch half shells or tools are the punching lines elaborated twisted by the helix angle.

When passing through the unprinted substrate, this turns on its front edge is gripped by the gripper Printing station 32 out and by means of printing units on itself known manner printed (left side, Fig. 14). Then this is also on the front edge of Grippers held in the substrate provided as the conveyor 33 Chain delivery 83 or the register roller 34 (Fig. 6) detected and the device 1 and 80 in the area of lower punch cylinder 4 or 82 with the diagonally mounted Hand over gripper. It is in the field of processing rollers 4, 5 or 81, 82 the drive side to the respective Operating side in height around the helix angle (dash-dot representations in Fig. 14), so that the Gripper bar of the lower processing roller (s) the corresponding Inclined and the necessary oblique transfer takes place when processing the substrate.

Located on the axially parallel transfer cylinders 84 and 85 the gripper bars, not shown, also mounted obliquely, so that in module 80 a harmonic Transfer of the substrate lying at an angle in the transport direction he follows. In the area of a subsequent boom 86 the substrate is in a direction extending in the conveying direction A. Position "not twisted" recorded by the boom 86 also around the helix angle (dash-dot representation) is shifted. The helix angle is 0.5 ° for each of the components described above, their arrangement means that the substrate on the Boom 86 is moved parallel to the conveying direction.
