Abstract

The invention relates to a method for aiding the setting of a punching device with a variable hole pattern (3). Said punching device is situated on a punching tool (40) and has a number of punches (42, 42a, 43), which can be displaced, at least in part and as desired into an active final position, inside of which they make a hole (4) in a material (1), or into a passive final position, in which they do not make a hole (4). The punching device also has controlling and evaluating means (500) in which the number of holes (4) required for the hole pattern (3) to be produced is firstly determined. The final position of the punches (42, 42a, 43), this final position being required for the hole pattern (3) that is to be produced, is then determined. Lastly, the final position of the punches (42, 42a, 43), this final position being required for the hole pattern (3) that is to be produced, is displayed to the operator via an operator interface (520, 530).

Description

The invention relates to methods for support of setting up a punching device with changeable hole pattern, according to the preamble of claim 1 and a device for performing the Process according to claim 12th

Such punching devices are found in many different areas of industry, depending on the material being processed. Devices for processing sheet metal or textiles, or cardboard and paper are often equipped with interchangeable punching tools in order to introduce different hole patterns into different materials. There are also punching tools that can produce changeable hole patterns without being replaced. One possibility here is to bring stamps which are mounted in the punching tool into an active end position, in which they create a hole in the material when actuated, or into a passive end position, in which the stamps do not when the device is actuated contribute to a hole. These punching tools can be rotary or linear tools, i.e. stamps that are attached to a shaft and create a hole pattern in interaction with a die roller, or stamps that create a hole pattern in a material by a linear displacement, such as how with a hand punch for paper. With some of these punching tools, the hole pattern consists of holes that lie on a line, others around holes that are distributed over a plane, similar to a matrix. Some of these punching devices process only one piece of material per processing operation, others process a stack of materials, especially when the materials are very thin, such as paper or foil. Some of these punching devices are automatically set up in that a control, by means of suitable adjusting means, brings at least some of the punches into one of the end positions. Such a device is, for example, from the German patent application DE 102 48 688 known. In the case of other generic devices, on the other hand, an operator is required who takes over the setting up and brings at least some of the stamps into one of the end positions by hand.

A special area of application for generic devices can be found in postpress in the printing industry. Here there is a need for punching substrates, especially for preparation for a binding process by means of which individually printed sheets are closed a brochure or a ring-bound book using wire comb or plastic binding together or, alternatively, to store the sheet-like substrates e.g. in Folders or flyers.

From the numerous from the stand Devices and methods for stamping known from the art holes in leaf-shaped Substrates form a group of devices and processes who perform on-the-fly processing of sheet-like substrates. there One understands by flying processing that the sheet-shaped printing materials processed in motion, in contrast to systems, where several leaf-shaped Printing materials in the idle state e.g. punched or cropped become. The sheet-shaped substrates are typically used during flying processing edited individually and then collected, whereas others Procedure the leaf-shaped Substrates first collected and processed afterwards. The flying editing of leaf-shaped In contrast, has printing materials the advantage that this editing better matches the workflow of a Printing machine for sheet-shaped substrates which typically corresponds to the sheet-shaped substrates sequentially printed. For this reason, on-the-fly editing is ideal for print finishing especially for so-called inline devices directly to such a printing machine, e.g. a digital one Printer or copier are connected. The flying processing is not bound to inline devices, but can also in so-called offline devices, that are not in direct contact with a printing press, advantageous be used. Such a device is, for example, from German patent application 101 37 165 known.

The hole patterns, which are in sheet-shaped substrates are essentially different in position and the number of holes that are punched. For example, a distinction is made between the European 2 or 4-hole hole pattern or the US 2, 3, 4, 5 or 7-hole hole pattern. In addition, different ring bindings, such as wire comb bindings, are required or plastic comb bindings, different hole patterns, which differ at the distance of the holes and their size and shape distinguish where the holes are e.g. are rectangular or round.

The following are examples of a generic device in which a change of a perforation pattern takes place manually from the printing industry. Similar examples can also be found in other branches of industry. In the US patent US 2,116,391 discloses a device for flexible adjustment of punching patterns in a punching device. Here, individual punches are fixed on axially movable sprockets. The sprockets, which are also equipped with a scale, ensure that the punches are positioned precisely on the circumference of the sprockets, the same applies to the positioning of the associated dies. In the solution proposed above, the stamps are individually in their intended position screwed. This allows a flexible change, but takes a lot of time.

In the US patent US 5,669,277 proposes a rotary punch device in which holders for punches for a large number of different hole combinations are provided in a first shaft. The change between different hole patterns is done by inserting or removing the stamp in question from the corresponding holders. This ensures a high precision of the stamp positions. On the other hand, it is disadvantageous that the stamps have to be exchanged and stored manually for each change of the stamping pattern.

In the German patent application DE 34 27 686 A1 discloses a device in which on a punching ring of a punching device a number of radially aligned punching punches are arranged, which are radially displaceable by means of internal cam rings between a first outer punching position and a retracted passive position. In addition, the punching rings can be moved on the shaft along the axis, so that a large number of different punching patterns can be created. The cam rings are also moved manually here.

When introducing rows of perforations along one Side of a leaf-shaped Substrate for a ring bond, e.g. It is wire comb or plastic binding beneficial if the holes such in the leaf-shaped Printing material are introduced, so that the perpendicular to it Edges of the leaf-shaped Substrate are not injured. It is therefore desirable a punching device is available by means of which this is possible is and with the also one if possible size available number punched into sheet-shaped substrates by different hole patterns and a change between the different hole patterns can be carried out quickly is. Therefore a suitable tool roller is required.

With all these punching devices variable Hole patterns where the operator manually punched set up to change the lace pattern can cause serious problems occur when the operator sets up a faulty hole pattern. Typically leads the punching process with a punching device where a wrong one Hole pattern is set up to destroy the workpiece, it can also destroy the Punching device itself come, for example, if that's the hole pattern generating stamp pattern not on a matching matrix pattern was established. Moreover setup by an operator can be very time consuming if the operator does not know exactly what to do, or but trained operators are required.

It would therefore be beneficial if the operator were on receive support from the machine at this point would, so the likelihood of setting up such errors a punch will decrease and the time to set up shortened at the same time becomes.

It is therefore the object of the invention a support process creating a punching device with a changeable hole pattern, with which a generation of a plurality of hole patterns is possible and a change between the hole patterns can be carried out quickly, easily and inexpensively can.

This task is accomplished with the help of inventive method solved with the features mentioned in claim 1 and with a device according to the claim 12. Further advantageous features emerge from the subclaims.

• a) Ermitteln der für das zu erzeugende Lochmuster erforderlichen Anzahl Löcher,
• b) Ermitteln der für das zu erzeugende Lochmuster erforderlichen Endposition der Stempel,
• c) Anzeigen der für das zu erzeugende Lochmuster erforderlichen Endposition der Stempel an einer Bedienerschnittstelle.

Accordingly, the method according to the invention is a method for supporting the setting up of a punching device with a changeable hole pattern, the punching device having a plurality of punches on a punching tool, which are at least partially optionally adjustable into an active end position in which they punch a hole produce a material or into a passive end position, in which they do not create a hole, and wherein the punching device comprises control means and evaluation means, with the following steps:

• a) determining the number of holes required for the hole pattern to be produced,
• b) determining the end position of the stamp required for the hole pattern to be produced,
• c) Displaying the end position of the stamp required for the hole pattern to be generated on an operator interface.

First of all, the hole pattern must be determined. This can be done, for example, by reading in data from the operator interface if the operator desires a prefabricated hole pattern. As an illustration, here is an example from further processing in the printing industry in which the operator inputs a sheet-shaped printing material or a stack of sheet-shaped printing materials is to be punched with a European 2-hole hole pattern or an American 5-hole hole pattern. In such a case, the determination generally only includes the step of reading out the number of holes for such a hole pattern from a reference table, since the number of holes is predefined here. In other cases, the step of determining requires more or less complex calculation and the querying of additional information. To stay with the example from further processing in the printing industry, here are perforated patterns in sheet form for different types of binding against substrates, especially for wire comb, plastic comb and spiral bindings. The number of holes that are to be made in the sheet-like substrates depends, among other things, on the format. In addition, it is to be avoided that a hole is punched into the outer edges or in the vicinity thereof, since this leads to a poor appearance, and / or the holes in the outer area can otherwise easily tear if a minimum distance is not maintained. It is therefore necessary to bring the punches into a passive end position at least in this area. Before doing so, however, it must be determined which punches must be brought into a passive end position, and thus first of all it must be determined how many holes the hole pattern that is to be introduced into the material has.

If the number of holes is known, must be determined which of the stamp in which end position should be. The determination can also be trivial here, e.g. if a punch has four punches, two of which are movable are and four holes all stamps must be in one active end position. In this example, there is a desired one Lace pattern from only two holes, have to both movable stamps must be in the passive end position.

The case is more complicated in the example of the hole pattern for a wire comb, plastic comb or spiral binding described above. A punching tool suitable for this purpose will advantageously have a whole series of stamps, the maximum number of which corresponds to the largest format of sheet-shaped printing materials that is to be processed with the punching device, for example 23 , Is now determined in the previous step that 22 Holes for a desired hole pattern are to be introduced into the material, then there are two possibilities, namely in that either the stamp on one side or the stamp on the other side of the stamp row is brought into the passive end position. Become 18 If you want to punch holes, there are already six different options, a series of stamps 18 To achieve stamping in the active position. Which stamp row should be selected from the six options depends, among other things, on how the sheet-like printing material or sheets is or are aligned relative to the stamps of the punching tool. It may therefore be necessary that additional information must also be obtained and processed in the step of determining the end position of the stamp.

The steps of discovering will be in one embodiment taken over by control means and evaluation means of the punching device, however can the steps of determining control means and evaluation means be performed, the outside the punching device are arranged and / or other devices assigned.

The operator is then connected to the investigation steps, depending order-specific of the hole pattern that he wants to create in the material displayed how the punching device should be set up to the Punching device on the next order prepare. By numbering or otherwise marking the Stamp and a corresponding numbering or marking of the stamp on the display, the operator can quickly check which of the stamps are are already in the correct end position and with which stamps a change the end position must become. This saves the operator time and the risk of that the stamps are in the wrong end position is reduced. This is particularly advantageous if the hole pattern is from others Depends on parameters, such as. from the dimensions of the material and the operator first Carry out calculations would have which stamps it should bring to an active end position and which to be brought into a passive end position.

Otherwise, it can be in the passive end position can also be an end position that is outside the punching device, e.g. on a shelf if the appropriate stamp is completely removed.

In an advantageous embodiment the inventive method additional help is stored on the user interface, which the operator can access as needed to learn what exactly he can do to put the stamp in one of the two end positions bring to. Animated graphics are particularly advantageous deposited, which illustrate the movements to be carried out by the operator, to get to the one you want Result to come. This makes it possible for even an untrained Operator can operate the punching device with ease.

• d) Ermitteln der aktuellen Endposition der Stempel durch Steuerungsmittel.

In a further advantageous embodiment of the method according to the invention, the method also comprises the following step:

• d) Determining the current end position of the stamp by control means.

Step d) can be carried out expressly at any point in the process and does not necessarily have to be carried out after steps a) to c) have been carried out. To determine the current end position of the stamps, measuring units are advantageously connected to the stamps, which indicate the current end position of the stamps to a higher-level controller. This makes it possible to display both the current and the required end position of the stamps on the operator interface, in particular in order to inform the operator which stamps should be changed and which stamps are already in the correct end position. This saves additional time because the operator does not have to check the end position of all stamps every time. al Alternatively, if no measuring units are attached to the stamps, the determination could also only include that this is called up and displayed from a memory in which the last end position of the stamps is stored. In this case, too, the stamps whose end position has yet to be changed could be highlighted. However, this requires that the operator actually put all the stamps in the correct end position during the last job, since the device would lack the possibility of checking the stamp position. On the other hand, such an alternative punching device would be less expensive. In the event that the stamps are removed from the punching tool and stored outside, a measuring device is sufficient to check whether a stamp is present or not. In this case, "installed" corresponds to the active end position and "removed" to the passive end position of the stamp ,

• e) Anzeigen, welches Stanzwerkzeug in der Stanzvorrichtung verwendet werden soll.

In a further advantageous embodiment of the method according to the invention, the punching tools of the punching device being exchangeable, the method comprises the step:

• e) Show which punching tool is to be used in the punching device.

If e.g. the desired hole pattern is different Should have stamp shape than that of the straight in the punching device built-in, the operator interface shows which Punching tool must be used to achieve the desired hole pattern, and which end positions the stamps of the exchanged punching tool assume should. This can e.g. by specifying a part number or a other identifiers of the punching tools. In an advantageous Design of such punching tools have electronics that are used during installation the punch into the punch control of the punch communicates the configuration of the built-in punch.

In a further advantageous embodiment of the inventive method are the required parameters when determining the number of holes sourced from at least one of the following sources: a parent Control, the operator interface, the punching tool. In certain embodiments the parameters are obtained from mixtures from these sources. The parent Control can be the control of the punching device in which e.g. the order parameters are stored, but it can also be a central control act the entire machining process of the material includes, if the punching only part of the processing represents. For example, could the material is first rolled, pressed, alloyed or otherwise treated be, or close it comparable processes to the punching process. If a complicated part from the material The machining parameters are to be produced inline typically from a central control to all processing stations directed, or passed from processing station to processing station. So-called job tickets, with which the processing parameters are sent to the Machining stations can also be given for offline machining stations be used if suitable data transmission means are available are.

A special example for the production of a complicated part is a book that is printed, punched, bound and is circumcised.

On the other hand, it can be a source of information be the operator interface at which an operator with suitable Input means can enter at least parts of the parameters by hand. As already described above, the stamping tool itself can also represent a source of information, if this with corresponding Information means is equipped, such as a memory from which e.g. the configuration of the punching tool can be read out.

In a further advantageous embodiment of the inventive method the step of determining the number of holes includes determining at least one of the following parameters: the dimensions of the material, the distance from hole to hole, the hole size, the hole shape.

In a further advantageous embodiment of the inventive method the material is sheet-shaped substrates, and the hole pattern around one of the following: the hole pattern for wire comb binding, the lace pattern for Spiral binding, the lace pattern for Plastic comb binding, the US 3-hole lace pattern, the US 5-hole lace pattern, the EP 2 hole pattern, the EP 4 hole pattern. In another advantageous embodiment of the method according to the invention At least determine the number of holes considered one of the following: the type of hole pattern, the minimum distance of the hole pattern to the Edge of the material, the number of adjustable stamps, the position the adjustable stamp in the punching tool.

In a further advantageous embodiment of the method according to the invention, when determining the end position of the stamp, an existing axis of symmetry of the material is taken into account in such a way that an existing axis of symmetry of the punching tool is as close as possible to the existing axis of symmetry of the material. This is particularly advantageous when processing materials in which the hole pattern is likewise to be introduced symmetrically to the axis of symmetry of the material. If the position of the punches within the punching tool is predetermined, an existing axis of symmetry of the punching tool will not always lie on the axis of symmetry of the material. This is particularly the case if the axis of symmetry of the punching tool does not coincide with the axis of symmetry of the hole pattern matches, for example because some of the stamps are in the passive end position and the existing symmetry of all stamps is broken as a result. For illustration, the example of a series of 23 Used stamps. If all of these 23 Stamp have the same distance from each other, then the axis of symmetry of the punching tool is in the middle of the twelfth stamp. When creating a hole pattern with 23 Holes lie one above the other on the axis of symmetry of the hole pattern and the tool. If the hole pattern is also to be introduced symmetrically into the material, then in this case typically the axis of symmetry of the material and the punching tool lie one above the other. It is different if a hole pattern is used with the same punching tool 22 Holes should be introduced. Depending on which side of the row of punches the one punch is brought into the passive end position, the axis of symmetry of the hole pattern shifts to the left or right of the axis of symmetry of the punching tool. Accordingly, the material must be aligned beforehand so that the symmetry axis of the hole pattern comes to lie above the symmetry axis of the material. Alternatively, the punching tool could also be aligned. In both cases, however, it is desirable if the mutual alignment of the punching tool and the material requires the smallest possible travel paths in order to achieve a quick and precise alignment.

• f) Ermitteln eines seitlichen Versatzes des Stanzwerkzeuges zur Erzeugung eines symmetrischen Lochbildes zu einer vorhandenen Symmetrieachse des Materials.

In a further advantageous embodiment of the method according to the invention, the method additionally comprises the following step:

• f) Determining a lateral offset of the punching tool to generate a symmetrical hole pattern to an existing axis of symmetry of the material.

This offset can then be sent to a for aligning hand over the responsible control of punching tool and material which carries out a corresponding automatic alignment, on the other hand, the required offset can also be done at the operator interface be displayed to indicate to the operator that it is manual should realize the appropriate offset to a good one Punching result to come.

• g) Ermitteln, ob die aktuelle Endposition der Stempel mit der in Schritt b) ermittelten Endposition übereinstimmt.

In a further advantageous embodiment of the method according to the invention, the method additionally comprises the following step:

• g) Determine whether the current end position of the stamp matches the end position determined in step b).

• h) Freigeben der Stanzvorrichtung, wenn die aktuelle Endposition der Stempel mit der in Schritt b) ermittelten Endposition übereinstimmt.

This represents a control step that the device carries out to check whether the operator has actually made the necessary changes. This in turn requires measuring units that transmit a control to the end position of the stamp. In an advantageous development of this embodiment of the method according to the invention, step g) is followed by the step:

• h) releasing the punching device when the current end position of the stamp matches the end position determined in step b).

This way you can ensure that the device is not damaged and actually the wished Hole pattern is generated because the device is prevented is started even though the operator does not put all the stamps in the has brought the required end position or accidentally entered Has released the stamp from its required end position.

The invention further relates to a device for generating a hole pattern in materials, with a number of N stamps, as well as a controller and an operator interface consisting of input means and display means being before generation a hole pattern in a material as described above carried out becomes.

Preferred embodiments of the device according to the invention are described in more detail below with reference to the drawing. In a schematic representation:

1a . 1b . 1c schematic views of different hole patterns in a sheet-like printing material,

2 a schematic representation of the operation of a punching tool with variable hole pattern;

3 a schematic representation of a stamp wave;

4 is a schematic representation of a device for generating hole patterns in sheet-like substrates;

5 is a schematic representation of an exemplary display of the end positions of the stamp according to the inventive method.

In 1a . 1b and 1c are sheet-shaped substrates 1 with different hole patterns 3 , E2, E4, US3, US5, LB1, LB2, LB3, LB4, LB5 shown schematically. In 1a is the hole pattern 3 for ring bindings by means of wire comb binding (so-called Wire-O) or for binding by means of plastic elements along one side of a sheet-like printing material 1 shown. The sheet-shaped printing material 1 has a length L and a width B, the length L being that direction of the sheet-like printing material 1 characterizes that along the transport path of the sheet-shaped printing materials by a device for flying generation of perforated images 40 runs. The width B indicates the direction parallel to the hole pattern 3 runs. In this direction, the sheet-like printing material has a front edge K3 which first enters the device and an opposite rear edge K4. The punch holes 2 have a fixed relationship to each other stood B0 and a fixed distance L1 from the rear edge K4. The punch hole closest to the outer edge K1 2 has a distance B1, the punch hole closest to the outer edge K2 2 has a distance B2. These distances K1, K2 are of the format of the sheet-like printing material 1 dependent, but may not fall below a minimum for reasons of strength against pulling out.

1 b shows the arrangement of the punch holes 2 with different hole patterns E2, E4, US3, USS, whereby here the European 2-hole pattern E2, the European 4-hole pattern E4, the American 3-hole pattern US3 and the American 5-hole pattern US5 are distinguished. 1c shows further hole combinations LB1, LB2, LB3, LB4, LB5 known to the person skilled in the art. The hole pattern LB1 is the hole pattern for a plastic comb binding with rectangular holes with the hole dimensions 8 × 3.2mm ² , the hole pattern LB2 is the hole pattern for a 2-1 wire comb binding with round holes with a 6 mm hole diameter, in which Hole pattern LB3 around the hole pattern for a 3-1 wire comb binding with round holes with a 4 mm hole diameter, with the hole pattern LB4 around the hole pattern for a wire comb binding with rectangular holes with the hole dimensions 6.35 × 5.44 mm ² and with the hole pattern LB5 around the hole pattern for a wire comb binding with square holes with the hole dimensions 4 × 4 mm ² .

The exact size of the spacing of the holes from one another is known to the person skilled in the art also known in European Hole pattern show the holes a diameter of 5 mm, in the Swedish hole pattern 5.5 mm and in the American hole pattern 8 mm. With the reference symbol M is the centerline of the leaf-shaped Marked substrates.

The 2 to 5 show different views of a preferred embodiment of a punch with variable hole pattern 1 and for the sake of clarity, we limit ourselves to the presentation of essential components. Further, generally known drive and / or guide means and cam disks as well as electrical circuits, which are required for operating the device, are only shown schematically, if so, or are only described in general form.

2 shows a section of a tool roller 41 with three stamps arranged side by side 42 , which are in different positions to clarify the functional principle of the stamp carrier. The tool roller 41 can be rotated around axis A1, compare 4 , On the circumference of the tool roller 41 is a stamp bar 50 appropriate. The stamp bar 50 is of fastening means, not shown, known to the person skilled in the art, for example screws or clamps, advantageously with the aid of centering means, which ensures a reproducible, exact position of the punch strip 50 on the tool roller 41 guaranteed on the tool roller 41 attached.

The stamp bar 50 has a plurality of holes 52 on the stamps 42 serve as a guide. In a preferred exemplary embodiment, the holes in the stamp bar are common with the holes for dies 42 ' for a die roller 41 ' (see 3 ) manufactured to ensure an optimal fit between stamps 42 and matrices 42 ' to achieve. The designation bore 52 here also includes holes which are produced, for example, by means of wire or die-sinking EDM or comparable processes known to the person skilled in the art. Otherwise, it is not necessary that the holes 52 are round. Since the stamp carrier and the stamps do not rotate themselves when they are adjusted, the bore can 52 and the corresponding side walls of the stamp 42 have any cross-section.

In the tool roller 41 are opposite the stamp bar 50 wells 413 introduced within which, essentially aligned with the holes 52 in the stamp bar 50 threaded holes 414 are brought up to the inside of the tool roll 411 pass. In an alternative embodiment of the tool roller 41 it is a single deepening 413 for all threaded holes 414 ,

A stamp carrier 44 consists essentially of a cone 47 , and a ring 46 that around the spigot 47 is arranged. The cone 47 has a pick-up mechanism on the first side 421 on, by means of which a stamp 42 on the stamp carrier 44 is attached. In one embodiment, the pick-up mechanism 421 around a grub screw 421 , with the stamp 42 has a corresponding internal thread. In the area of the stamp holder 44 who got the stamp 42 has, is the pin 47 from the grub screw 421 apart from flat and has a larger diameter than the bore 52 on. This remains in the assembled state between the stamp 42 and the cone 47 the first stop surface 60 ,

Are the stamp carriers 44 into the tool roller 41 installed, the stamp carrier 44 assume three different positions, namely a passive end position, an undetermined middle position and an active end position. The in 2 stamp carrier shown on the left 44 is in the passive end position at which the stamp 42 not about the stamp bar 50 protrudes and accordingly not to the creation of a hole 2 can contribute. The in 2 stamp carrier shown in the middle 44 is in the indefinite middle position at which the stamp carrier 44 on none of the stop surfaces 60 . 65 in contact with the corresponding stops 51 respectively. 412 stands. None of the stamp carriers 44 should change during tool roll operation 41 are in this position because the stamp carrier 44 is not secured in this position and due to the vibrations and movements during operation of the tool roller could move so far that the stamp 42 above or below the stamp bar 50 pushes, and thereby to an unwanted hole 2 contributes or accordingly no desired hole 2 generated. The in 2 stamp carrier shown on the right 44 is in the active end position at which the stamp 42 via the stamp bar 50 protrudes and corresponding to the creation of a hole 2 contributes.

The stamp carrier is in the active end position 44 with an actuator 47 ' in connection. With the control element 47 ' in one embodiment it is a set screw 47 ' , The set screw 47 ' is in a thread 414 in the tool roller 41 guided. Alternatively, there is the thread 414 in a plate, not shown, on the tool roll 41 is attached. The stamp carrier 44 is from the return spring 45 in contact with the surface 47 '' the set screw 47 ' held. Here is the surface 47 '' the set screw 47 ' spherically shaped so that the contact point consists approximately of a point, which causes wear of the stamp carrier 44 and set screw 47 ' can be reduced. There are also stamp carriers 44 and set screw 47 ' hardened at least in this area to further reduce wear. The set screw 47 ' also has a step between a cylindrical surface and the thread 414 on. Will the set screw 47 ' unscrewed, the stamp carrier follows 44 due to the spring tension of the return spring 45 up to the passive end position of the stamp carrier, at which the ring 46 at the second stop 412 is applied. Will the set screw 47 ' screwed out further, the adjusting screw loses 47 ' first the contact with the stamp carrier 44 and the level of the set screw described above 47 ' comes into contact with a stop 415 in the tool roller 41 and can be locked there. This will make the stamp carrier 44 with the reproducible pressure of the return spring 46 at the second stop 412 pressed.

At the end of the set screw 47 ' is a screw attachment 48 provided that allows an operator the position of the set screw 47 ' and thus the stamp carrier 44 to change along its axis A3 in the direction of movement, which is indicated by the arrow P1. The axis A3 does not have to coincide with the rotation axis of the adjusting screw 47 ' agree, in practice this would only be achieved with an undesirably high level of effort anyway, but it is also unnecessary since the rotary movement of the set screw and the vertical displacement of the stamp carrier are not coupled to one another. The screw approach 48 is shaped according to a suitable tool, such as a torque wrench. The screw approach 48 is cut to length so that it is in contact with the stop 415 not about the circumference of the tool roller 41 protrudes so that no damage to the stamp carrier 44 or an opposing matrix roller 41 ' can arise. However, it would also be conceivable in such a matrix roller 41 ' provide suitable recesses, not shown, in which the protruding ends of stamp carriers would pass.

To the cone 47 is a return spring 45 arranged. The return spring is supported on the one hand on the underside of the stamp bar 50 and on the other hand on the ring 46 of the stamp holder 44 from. On the other side of the ring 46 is the second stop surface 65 provided that in the passive end position of the stamp carrier 44 to the attack 412 is pressed. The attack 412 is part of the surface of the tool roll inside in this embodiment 411 It is immediately clear to the person skilled in the art that, for this purpose, specially provided stops can also be provided which do not form part of the surface of the interior of the tool roll 411 are.

Although the stamp holder 44 was described in the foregoing consisting of various parts, it is clear to the person skilled in the art that it is the stamp carrier 44 typically a one-piece component. In fact, it is also conceivable to use the stamp carrier 44 from the individual elements 421 . 46 , and 47 reassemble. Incidentally, it is not necessary that the pin 47 or the ring 46 has a cylindrical cross section since the stamp carrier 44 is not rotated during the up and down movement itself.

The operator can now use a suitable tool to create different hole patterns 3 generate in which he the appropriate stamp carrier 44 in the corresponding active or passive end position and fixed there at the stops. If the torque used for this is limited by a torque wrench, for example, the fit between the corresponding stops can be used 51 . 412 with the stop surfaces 60 . 65 of the stamp holder 44 very high precision and reproducibility of the end position of the stamp 42 achieve. This is particularly important for the active end position, in order to damage the dies 42 ' to avoid and high quality holes 2 to create.

In 3 is an exemplary tool roll 41 and matching die roller 41 ' shown which is rotatably mounted about an axis A2 and illustrates the special case of adapting a hole pattern 3 for wire or plastic comb binding to the format of a sheet-like printing material 1 , In such hole patterns LB1, LB2, LB3, LB4, LB5 are the stamps 42 equidistant in three areas 491 . 492 . 493 appropriate. In the middle area 493 are the stamps 42 not a stamp carrier 44 assigned, but are directly with the stamp bar 50 connected, namely by means of a thread 431 in the stamp bar 50 screwed. Here, too, alternative fastening means can be expressly implemented, and also in the middle area 493 the stamp 43 instead of the stamp bar 50 also directly with the tool roller 41 be connected.

Become sheet-shaped substrates 1 with the tool roller 41 always processed so that the center line M of the sheet-like printing material coincides with the center of the tool roller, there is a central area 493 , which is roughly the size of the smallest sheet-size substrate 1 corresponds to a hole in all formats when creating a hole pattern LB1, LB2, LB3, LB4, LB5 for wire or plastic comb binding 2 must be generated. It is therefore unnecessary in this middle range 493 the stamp 43 to bring from their active end position into a passive end position. Correspondingly, the cost can be reduced in the middle range 493 on the stamp carrier 44 to be dispensed with. Starting from the smallest format, a change in such a hole pattern LB1, LB2, LB3, LB4, LB5 can be achieved by the stamps adjoining the central area 42 in the first and second outer areas 491 . 492 can also be brought into an active position from the inside out. In principle, it is also sufficient, only the stamp 42 in the first and second area 491 . 492 to bring into a passive end position, which is in the vicinity of the outer edges K1, K2 of the sheet-like printing material 1 lie. All other stamps 42 can always be in an active end position. This enables the changeover time to be shortened, since when changing the format only those in the vicinity of the outer edges K1, K2 of the sheet-like printing material 1 lying stamp must be moved, or those previously in the vicinity of the outer edges K1, K2 of the sheet-like printing material 1 lay. In the example shown there are a number of 4 Stamping shown in an active end position, the outermost ones are in the passive end position. It's over 1c immediately clear that to generate a corresponding hole pattern LB1, LB2, LB3, LB4, LB5 a significantly larger number of stamps 42 . 43 and stamp carriers 44 is to be provided and that is the limitation to six stamps 42 . 43 on the tool roller 41 was chosen for illustration purposes only.

Every stamp 42 . 43 is a corresponding matrix 42 ' assigned. The inside of the die 43 ' provides a passage to the inside of the die roll 411 ' through which the punching waste can be removed.

As in 4 is shown, the die roller 41 ' by means of an engine 402 over a belt pull 403 driven. On the axis of the die roller 41 ' there is a gear 404 that with another gear 405 that is on the axis of the tool roll 41 is fixed, is engaged and the rotation of the die roller 41 ' in the reverse direction of rotation synchronously on the tool roller 41 transfers. matrix cylinder 41 ' and tool roller 41 are in one housing 401 arranged. The tool roller 41 stands over a tool shaft 460 in connection with the engine 402 , The functional position of the tool shaft 460 is through a sensor 480 monitored and to a higher-level control 500 , which also drives the device via a control of the motor 402 performs, handed over. This is on the tool shaft 460 a marker 481 provided the functional position of the tool shaft 460 identifiable, for example in the form of a pinhole 481 , In this case it is the sensor 480 around an optical sensor 480 , Magnetic or other coding or a corresponding sensor is also conceivable, among other things, to determine the functional position of the tool roller 41 to determine.

As in the 2 and 3 are shown on the stops 51 . 412 measurement units 510 . 512 intended. These units of measurement 510 . 512 deliver a signal when the stamp carrier 44 with its stop faces 60 . 65 at the corresponding stops 51 . 412 invests. For the measuring units 510 . 512 it is, for example, resistance-dependent sensors, which are caused by the presence of the stamp carrier stop surfaces 60 . 65 a circuit is closed. However, capacitive, magnetic, optical or other sensors are also conceivable, as are known in large numbers to the person skilled in the art from the prior art. The measuring units 510 . 512 stand with the controller 500 connected, and share control 500 with whether the stamp 42 is in the active or passive end position. This information is used to give an operator the end position via an operator interface 520 . 530 notify and possibly stop the punching device, if by the measuring units 510 . 512 determined active or passive end positions do not match the required active or passive end positions.

In 5 is a punching tool 40 With 23 Stamp 42 shown in a row, as well as a material 1 that's a lace pattern 3 got that stamped in there 42 corresponds to which were in an active end position. At the same time, there is a schematic representation of the punching tool 40 and sheet-shaped printing material 1 with lace pattern 3 in 5 a possible embodiment of a display on a display means 530 , The numbering of the stamp 42 on the display means 530 of 1 to 23 corresponds to a numbering that the operator also uses on the actual stamps 42 in the punch 40 finds again in order to create an assignment. A different assignment can be a color coding, although color coding can have defects known to the person skilled in the art, such as a lack of distinctive character in the case of color blindness of the operator. The one with the reference number chen 493 The designated border means the stamp in this embodiment 43 on the punch 40 are not movable, so always stay in the active end position. The filled rectangles symbolize the stamp 42 . 43 the one for the hole pattern 3 must be in the active end position, the rectangles not filled symbolize the stamp in this representation 42 that should be in a passive end position. These are in particular those with the reference symbol 42a marked stamp 42a that in the area of the outer edges K1, K2 of the sheet-shaped printing material 1 would arrive. In an embodiment, not shown, the stamp 42 additionally on the display means 530 highlighted, which correspond to the information of the control 500 are not in the required end position. The controller obtains this information 500 either of measurement units 510 . 512 , if these exist, or from memory where the last setting of the stamp 42 is saved. Alternatively, an operator could also use input means 520 enter the current end position of the stamp. With input means 520 are input means known from the prior art 520 such as a mouse, pointers, keyboards, etc. With the display means 530 it is typically a screen.

The display means 530 can also indicate the offset Δ between the center line MW of the punch 40 and the center line MB of the sheet-like printing material. This offset could then be set manually by an operator, on the other hand the control can 500 also pass on the required offset Δ to suitable actuating means, not shown, which precisely align the sheet-like printing material 1 and punching tool 40 carry out.

The sequence of the method is illustrated below using the punching device described above 40 described. However, it is clear to the person skilled in the art that the method according to the invention is not restricted to this application, but can be used for any materials and punching devices, but the exact embodiments of the steps of the method according to the invention can differ considerably from those described here, depending on Complexity of hole pattern and punch.

The controller first determines 500 the parameters "TOOL_MAX_HOLES", namely the maximum number of stamps 42 . 43 of the punching tool 40 , "TOOL_FIXED_HOLES", namely the number of fixed punches, it being assumed that fixed punches are always arranged in the center of the tool, "TOOL_PITCH", namely the hole spacing measured from hole center to hole center, and "TOOL_HOLE_SIZE", namely the hole size directly from the punch 40 , The punching tool 40 has an electronic identifier (not shown) that is used when inserting the punching tool 40 the control 500 is made available to the higher-level punching device and, in addition to the parameters described above, may also contain additional data, for example the number of work cycles already performed, production date, part number, etc.

The controller takes over other data 500 from a memory in which a system configuration is stored, in particular the parameter "BINDING_MIN_MARGIN", namely the minimum edge distance for the respective binding application measured from the binding edge to the center of the hole. This differs, for example, in wire or plastic comb binding or spiral binding and can also depend on the material properties of the sheet-like printing material 1 be the basis for the pending order. The control system could have obtained information about the material properties, for example from a higher-level control system that coordinates the entire production of a book.

Further parameters can also be obtained from such a higher-level control or directly from the operator at the operator interface 520 . 530 with the input means 520 can be entered. The parameters that are still missing in this exemplary embodiment are "JOB_PAPER_SIZE", namely the desired paper size, "JOB_PITCH", namely the desired hole spacing from hole center to hole center and "JOB_HOLE_SIZE", namely the desired hole size. The punching tool may have to be used to adapt the hole pattern to the last two parameters 40 are exchanged if the required hole size "JOB_HOLE_SIZE" or the desired hole shape and the distance from hole to hole "JOB_PITCH" does not correspond to what the built-in punching tool does 40 offers, ie "TOOL_HOLE_SIZE" or "TOOL_PITCH". In this case, the control is checked accordingly 500 to the operator on the display means 530 is communicated which punching tool 40 should be installed to the desired hole pattern 3 to be able to realize.

From the parameters "JOB_HOLE_SIZE", "JOB_PITCH", "JOB_PAPER_SIZE" and "BINDING_MIN_MARGIN", the maximum number of holes is first determined for a desired hole pattern on the sheet-like substrate 1 fit so that a symmetrical hole pattern is created and the minimum distance to the edges is observed. Another parameter that may be provided is "JOB_HOLE_COUNT", namely the desired number of holes, the operator being able to choose between "maximum" and "user specified". In the latter In this case, the operator can specify a number of holes between the previously determined maximum value for the paper size and the minimum value of the punching tool 40 may lie. The minimum value corresponds to the number of stamps 43 that in the middle area 493 are permanently installed. If a value for "JOB_HOLE_COUNT" is specified or the maximum value is used, the determination of the number of holes has been completed. The number of holes can be calculated using simple geometric relationships, or can be read from a suitable reference table in accordance with the determined parameters.

The control and evaluation means 500 determine the end positions of the stamp in the next step 42 , i.e. whether the stamps should be in an active or passive end position.

The controller calculates the following values for this:
Number of adjustable stamps:
TOOL_VARIABLE_HOLES = TOOL_MAX_HOLES - TOOL_FIXED_HOLES
Number of adjustable stamps "back":
INTEGER (TOOL_VARIABLE_HOLES / 2), where INTEGER is a function that returns the integer part of a number, i.e. INTEGER (3, 9) = 3 and INTEGER (-3, 9) = -3, so it is rounded down.
Number of adjustable stamps "front":
TOTAL (TOOL_VARIABLE_HOLES / 2 + 0.5), so here is rounded up.
Maximum number of holes allowed for the specified binding edge (JOB_MAX_HOLES):
INTEGER ((JOB_PAPER_SIZE - 2BINDING_MIN_MARGIN - TOOL_HOLE_SIZE) / TOOL_PITCH + 1)
Number of stamps 42 in the passive end position:
RETRACTED_DIES = TOOL_MAX_HOLES-JOB_HOLE_COUNT
Number of stamps 42 in the passive end position "back", ie stamp 1 to H:
H = TOTAL (RETRACTED_DIES / 2)
Number of stamps 42 in the passive end position stamp "front", ie stamp
TOOL_MAX_HOLES - V to TOOL_MAX_HOLES:
V = TOTAL (RETRACTED_DIES / 2 + 0.5).
The division "/" is the integer division. So 3/2 = 1.

This is all stamps 42 determined that are in the passive end position, from the reverse conclusion all stamps can be 42 . 43 determine which should be in an active end position, since all stamps 42 either in the active or in the passive end position and not in between. The control and evaluation means generate from the results of these calculations 500 a display of display means 530 , about: "Please check the tool setting and make sure that the stamp 1 - 3 and 21 - 23 in the retracted state, "alternatively or additionally, a suitable graphic can be on the display means 530 be provided which the required end position of the stamp as in 5 shown shown.

Can the control by means of the measuring units 510 . 512 determine which stamp 42 which end position is located, the operator can additionally display which stamps on the display means 520 42 change the end position.

In addition, it is provided in an alternative embodiment that only the stamp 42a be brought into a passive end position, since the end position of the stamp is outside the sheet-like printing material 1 is actually indifferent.

In a further step, the control and evaluation means determine 500 the offset Δ between the center line MW of the punch 40 and the center line MB of the sheet-like printing material 1 according to the formula (RETRACTED_DIES / 2 - TOTAL (RETRACTED_DIES / 2)) · TOOL_PITCH. This offset Δ is either given to the operator via the display means 530 displayed or forwarded directly to suitable actuating means, not shown, which compensate for the offset Δ.

The procedure for support of setting up a punching device with a changeable hole pattern its application in all punching devices with changeable Lace pattern, independent of the processing material, i.e. for punching devices for metal sheets, Textiles, paper, plastic films, canon, etc. It does not matter whether a single material or a stack of materials simultaneously to be edited. The one described here is particularly useful Support procedures of setting up a punching device with a changeable hole pattern at Inline processing of print products from digital printing machines with suitable integrated punching device with changeable Hole pattern. Use in all copiers / printers where leaf-shaped Post-processing of substrates is also possible, especially also use in offline processing. Furthermore it is conceivable, the stamp carrier too for a Floor standing to use a die cut pattern in stacks of sheet-like substrates brings in and if possible should be user-friendly.
