Description

Tool roller for creating different hole patterns in sheet-like substrates

The invention relates to a tool roller for producing different hole patterns in sheet-like printing materials, according to the preamble of claim 1.

In the printing industry, there is a need for punching printing materials, in particular in preparation for a binding process, by means of which individually printed sheets are combined to form a brochure or a ring-bound book by means of wire comb or plastic binding, or alternatively for storing the sheet-shaped printing materials, e.g. in folders or flyers.

From the numerous devices and methods for punching holes in sheet-shaped printing materials known from the prior art, a group of those devices and methods form a device for the flying processing of sheet-like substrates

Perform substrates. In this case, flying processing means that the sheet-like substrates are processed in the moving state, in contrast to systems in which several sheet-like substrates in the stationary state, e.g. to be punched or trimmed. Typically, in sheet processing, the sheet-like substrates are individually processed and then collected, whereas in other processes, the sheet-like substrates are first collected and subsequently processed. In contrast, the flying processing of sheet-like printing materials has the advantage that this processing corresponds better to the workflow of a printing machine for sheet-like printing materials, which typically prints the sheet-like printing materials sequentially. That is why it is flying

Processing for print finishing, especially for so-called inline devices, which are connected directly to such a printing press, for example a digital printer or copier. However, the on-the-fly processing is not tied to inline devices, but can also be used advantageously in so-called offline devices which are not in direct contact with a printing machine. Such a device is known for example from German patent application 101 37 165. The hole patterns that are introduced into sheet-shaped printing materials essentially differ in the position and the number of holes that are punched. For example, a distinction is made between the European 2 or 4 hole pattern or the US 2, 3, 4, 5 or 7 hole pattern. In addition, different ring bindings, such as wire comb bindings or plastic joint bindings, require different hole patterns, which differ in the spacing of the holes and their size and shape, in which the holes are, for example, rectangular or round.

It is advantageous to make a punching device as flexible as possible, since the requirements e.g. can change the position of the holes or their number from one print and / or further processing order to the next. US Pat. No. 2,116,391 discloses a device for flexibly setting 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 screwed individually in their intended position. This allows a flexible change, but takes a lot of time.

US Pat. No. 5,669,277 proposes a rotary punch device in which holders for punches are provided in a first shaft for a large number of different hole combinations. The change between different hole patterns is done by inserting or removing the stamp in question from the corresponding holders. This ensures high precision of the

Stamp positions reached. 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 published patent application DE 3427 686 A1, a device is disclosed in which a number of punching dies, which are aligned radially and at certain distances from one another, are attached to a punching ring of a punching device inner cam rings between a first outer punching position and a retracted passive position are radially displaceable. 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.

When introducing rows of perforations along one side of a sheet-like printing material for a ring binding, e.g. Wire comb or plastic binding, it is advantageous if the holes are made in the sheet-like printing material in such a way that the edges of the sheet-like printing material running perpendicular to it are not damaged. It is therefore desirable to provide a punching device by means of which this is possible and with which the largest possible number of different hole patterns can be punched into sheet-shaped printing materials and a change between the different hole patterns can be carried out quickly. A suitable tool roller is required for this.

It is therefore the object of the invention to provide a suitable tool roller for producing different hole patterns in sheet-like printing materials, with which a plurality of hole patterns can be generated and a change between the hole patterns can be carried out quickly, easily and inexpensively.

This object is achieved with the aid of the tool roller according to the invention with the features mentioned in claim 1. Further advantageous features emerge from the subclaims.

Accordingly, at least one stamp is releasably connected to a stamp carrier, the at least one stamp carrier being movably mounted between a first stop and a second stop inside the tool roll, the first stop defining an active end position of the stamp and the second stop a passive end position of the stamp Are defined. Advantageously, a plurality of stamps of the tool roll are connected to corresponding stamp carriers, so that a plurality of different hole patterns can be realized. Can be used in special applications also all stamps of the tool roller are each equipped with a corresponding stamp carrier, as explained below, but this is not absolutely necessary. In a modification of the device according to the invention, two or more stamps can also be assigned to a common stamp carrier, so that these two or more stamps can only be brought together into an active or passive end position.

As a result, the stamp can always remain connected to the tool roller and does not have to be kept outside the tool roller. By providing the stops, it can be ensured that the punches are positioned precisely and reproducibly in the intended active and passive end position and that these end positions are not left during the operation of the tool roller. It is therefore quick, easy and with great precision for the operator to move the punches from a passive end position, in which they do not contribute to the creation of a hole in a hole pattern, to an active position, in the respective punches to create a hole in one Contribute hole pattern.

In a further advantageous embodiment of the tool roller according to the invention, the at least one stamp carrier is at one end in contact with an actuating element, by means of which the stamp carrier can be moved into the active end positions. The adjusting element is in particular an adjusting screw which is guided in a thread which is located in the tool roller or in a plate which is fastened to the tool roller. The set screw advantageously has a spherical surface at the point of contact with the stamp carrier. This reduces wear on the stamp carrier or the screw. Advantageously, the stamp carrier and the actuating element are hardened at least at their contact point. The stamp carrier is only guided in the area of the stamp, since it is connected to it. The guidance of the stamp is not necessarily aligned with the guidance of the actuating element. Other adjusting elements known to the person skilled in the art can also be used instead of an adjusting screw. In a further advantageous embodiment of the tool roller according to the invention, the at least one stamp carrier is acted upon by a return spring. The return spring serves to ensure the contact between the stamp carrier and the actuating element at all times. The return spring biases the stamp carrier towards its passive end position. When actuated, the actuating element pushes the stamp carrier against the spring force of the return spring to the active end position of the stamp carrier. If the actuating element is withdrawn, the stamp carrier follows due to the spring tension and remains in contact with the actuating element until the passive end position.

In a further advantageous embodiment of the tool roller according to the invention, the connection between the at least one stamp and the at least one stamp carrier is a detachable connection, in particular a screw connection. This means, among other things, a tool change, e.g. easier with a damaged stamp or changing the stamp geometry. Instead of the screw connection, any other detachable connection known to the person skilled in the art is also possible, such as catches or latches.

In a further advantageous embodiment of the tool roller according to the invention, at least one stamp bar is attached to the stamp shaft, in which at least one stamp is guided. It is advantageously a stamp bar in which the majority or all of the stamps are guided. On the one hand, a ram bar that can be retrofitted and is independent of the tool shaft can facilitate the assembly of the tool roller. In addition, a suitable material can be used for the stamp bar, which differs from the material of the tool roll, for example: has a different degree of hardness. Another advantage of a stamp bar that is independent of the tool roller is that it can be produced together with the die, against which the built-in stamps punch the sheet-shaped printing materials. In this way, great precision can be achieved in the interaction between the die and the punch, which is of great advantage for the production of high-quality hole patterns. In a further advantageous development of this embodiment of the tool roller according to the invention, the punch bar defines the first stop on its underside. These are precisely the areas of the stamp bar which lie around the guides of the stamp on the side of the stamp bar facing the interior of the tool roll. In addition, the stamp bar serves as a contact surface for the return spring. Other stops are conceivable, but the underside of the stamp bar is particularly cheap because it is present anyway.

In a further advantageous embodiment of the tool roller according to the invention, the at least one stamp has on its top one of the following stamp shapes: oval, circular, semi-circular, polygon, rectangular, square. The change between these stamp shapes advantageously takes place by loosening the releasable connection between the stamp and the stamp carrier and attaching a stamp with a different stamp shape. Alternatively, such a tool change can also require the replacement of a suitable stamp bar if the geometry of the stamp differs in addition to the stamp shape. It is also possible to change stamps and stamp carriers together.

In a further advantageous embodiment of the tool roll according to the invention, the inside of the stamping roll has a continuous inside of the stamping roll, the inside of the stamping roll serving at least in sections as a second stop. Alternatively, a further bar corresponding to the stamp bar can be used in this area to serve as a second stop. In any case, the second stop is at least so flat that an exact stop of the stamp carrier is possible at this point.

In a further advantageous embodiment of the tool roller according to the invention, the stamp shaft has a central region in which the stamps always remain in an active position. Such an arrangement is particularly advantageous if the hole patterns to be introduced are hole patterns intended for wire or plastic comb binding. These hole patterns consist of a variety, one constant distance from each other with the same shaped holes. A change in such a hole pattern is that the number of holes is adapted to the format of the sheet-like printing material. This is necessary in order to avoid that the position of a hole coincides with one of the outer edges of the sheet-like printing material. A hole that hurts the outer edges of the sheet-like printing stock deteriorates the appearance and typically reduces the value of a booklet bound by wire or plastic comb binding. In addition, the stability of the binding is reduced if there is also no minimum distance to the outer edges. The minimum distance between the hole and the edge of the sheet-like substrate results from

Stability considerations to avoid tearing out the holes in the bound booklet.

However, the adaptation of the hole pattern to the format of the sheet-like printing material via the number of holes has a practical lower limit, namely the smallest

Format to be processed with a device. This means that the holes that lie within the outer edges of the smallest sheet-type printing material to be processed are present in all formats to be processed. Accordingly, the punches assigned to these holes must always be in an active position. It is therefore not necessary to imitate the stamp in this area of the

Tool roll retractable. This saves significant parts costs and accelerates the assembly of the tool roll according to the invention. Moreover, it is not necessary to sink all the stamps that laterally go beyond the format of the sheet-type printing material in question, but only the stamps in question that are currently located on both sides in the edge regions, since the stamps positioned further out merely "punch out air".

In a further advantageous embodiment of the tool roll according to the invention, the tool roll forms part of a device for the flying, rotary production of different hole patterns with at least one additional die roll which is driven in the opposite direction to the tool roll and which is in relation to that Tool roller is arranged so that the stamp of the tool roller and matrices of the die roller cooperate to produce the hole patterns in a sheet-like printing material.

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

La, Fig. 1b and Fig. 1c schematically show sheet-shaped printing materials 1 with different hole patterns 3, E2, E4, US3, US5, LB1, LB2, LB3, LB4, LB5. 1 a shows 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. The sheet-like printing material 1 has a length L and a width B, the length L characterizing that direction of the sheet-like printing material 1 which runs along the transport path of the sheet-shaped printing materials by a device for the flying generation of perforated images 40. The width B indicates the direction that runs parallel to the hole pattern 3. 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 punched holes 2 are at a fixed distance B0 from one another and from the rear edge K4 at a fixed distance L1. That the Punch hole 2 closest to outer edge K 1 is at a distance B1, and punch hole 2 closest to outer edge K2 is at a distance B2. These distances K1, K2 depend on the format of the sheet-like printing material 1, but may not be less than a minimum for reasons of strength against tearing.

1b shows the arrangement of the punched holes 2 with different hole patterns E2, E4, US3, US5, the European 2-hole pattern E2, the European 4-hole pattern E4, the American 3-hole pattern US3 and the American 5- Hole pattern US 5 can be 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 x 3.2 mm ² , the hole pattern LB2 is the hole pattern for a 2-1 wire comb binding with round holes with 6 mm hole diameter the 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 Dralit comb binding with rectangular holes with the hole dimensions 6.35 x 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 x 4 mm ² .

The exact size of the spacing of the holes from one another is also known to the person skilled in the art; in the European hole pattern the holes have a diameter of 5 mm, in the Swedish hole pattern 5.5 mm and in the American hole pattern 8 mm. The center line of the sheet-like printing materials is identified by the reference symbol M.

FIGS. 2 to 4 show different views of a preferred embodiment of the device 40, 41 according to the invention and, for the sake of clarity, are limited to the representation of components essential to the invention. 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 according to the invention with three stamps 42 arranged next to one another, which are located in different positions to illustrate the principle of operation of the stamp carrier. The tool roller 41 is rotatable about the axis AI, see FIG. 4. On the circumference of the tool roller 41, a punch bar 50 is attached. The punch bar 50 is fastened to the tool roll 41 by fastening means, for example screws or clamps, not shown, known to the person skilled in the art, advantageously with the aid of centering means, which ensures a reproducible, exact position of the stamp bar 50 on the tool roller 41.

The stamp bar 50 has a plurality of bores 52, which serve as a guide for the stamps 42. In a preferred exemplary embodiment, the holes in the punch bar are made together with the holes for dies 42 'for a die roller 41' (see FIG. 3) in order to achieve an optimal fit between dies 42 and dies 42 '. The designation bore 52 here also includes holes which e.g. by means of wire or die sinking or comparable processes known to the person skilled in the art. Moreover, it is not necessary for the bores 52 to be round. Since the stamp carrier and the stamps do not rotate themselves during the adjustment, the bore 52 and the corresponding side walls of the stamp 42 can have any cross sections.

In the tool roll 41, 50 recesses 413 are made opposite the punch bar, within which, essentially flush with the bores 52 in the punch bar 50, threaded bores 414 are made which extend into the interior of the tool roll 411. In an alternative embodiment of the tool roller 41, there is a single depression 413 for all threaded bores 414.

A stamp carrier 44 consists essentially of a pin 47 and a ring 46 which is arranged around the pin 47. The pin 47 has a receiving mechanism 421 on the first side, by means of which a stamp 42 on the Stamp carrier 44 is attached. In one embodiment, the receiving mechanism 421 is a threaded pin 421, the plunger 42 having a corresponding internal thread. In the region of the stamp carrier 44, which has the stamp 42, the pin 47 is flat apart from the threaded pin 421 and has a larger diameter than the bore 52. As a result, the first stop surface 60 remains in the assembled state between the punch 42 and the pin 47.

If the stamp carriers 44 are installed in the tool roller 41, the stamp carriers 44 can assume three different positions, namely a passive one

End position, an undefined middle position and an active end position. The stamp carrier 44 shown on the left in FIG. 2 is in the passive end position, in which the stamp 42 does not protrude beyond the stamp strip 50 and accordingly cannot contribute to the creation of a hole 2. The stamp carrier 44 shown in the middle in FIG. 2 is in the undefined middle position, in which the stamp carrier 44 is not in contact with the corresponding stops 51 or 412 on any of the stop surfaces 60, 65. None of the stamp carrier 44 should be in this position during the operation of the tool roller 41, since 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 over or under the punch bar 50, thereby contributing to an undesired hole 2 or correspondingly not producing a desired hole 2. The stamp carrier 44 shown on the right in FIG. 2 is in the active end position, in which the stamp 42 projects beyond the stamp bar 50 and accordingly contributes to the creation of a hole 2.

In the active end position, the stamp carrier 44 is connected to an actuating element 47 '. In one embodiment, the adjusting element 47 'is an adjusting screw 47'. The set screw 47 'is guided in a thread 414 in the tool roller 41. Alternatively, the thread 414 is located in a plate, not shown, which is fastened to the tool roller 41. The stamp carrier 44 is replaced by the return spring 45 held in contact with the surface 47 "of the set screw 47 '. The surface 47" of the set screw 47' is spherical in shape, so that the contact point approximately consists of one point, whereby wear on the stamp carrier 44 and set screw 47 'can be reduced. In addition, stamp carrier 44 and set screw 47 'are hardened at least in this area in order to further reduce wear. The set screw 47 'also has a step between a cylindrical outer surface and the thread 414. If the set screw 47 'is unscrewed, the stamp carrier 44 follows the return spring 45 due to the spring tension to the passive end position of the stamp carrier, at which the ring 46 abuts the second stop 412. If the adjusting screw 47 'is unscrewed further, the adjusting screw 47' initially loses the

Contact with the stamp carrier 44 and the previously described step of the adjusting screw 47 'comes into contact with a stop 415 in the tool roller 41 and can be locked there. As a result, the stamp carrier 44 is pressed against the second stop 412 with the reproducible pressure of the return spring 46.

At the end of the adjusting screw 47 ', a screw attachment 48 is provided which allows an operator to change the position of the adjusting screw 47' and thus the stamp carrier 44 along its axis A3 in the direction of movement, which is identified by the arrow P1. The axis A3 does not have to coincide with the axis of rotation of the set screw 47 ', 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 attachment 48 is shaped in accordance with a suitable tool, for example a torque wrench. The screw attachment 48 is cut to length so that it does not protrude in contact with the stop 415 over the circumference of the tool roller 41, so that no damage can occur to the stamp carrier 44 or to a die roller 41 'arranged opposite it. However, it would also be conceivable to provide suitable not shown recesses in such a die roller 41 ', in which the protruding ends of stamp carriers would pass. A return spring 45 is arranged around the pin 47. 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 carrier 44. The second stop surface 65 is provided on the other side of the ring 46 and is pressed against the stop 412 in the passive end position of the stamp carrier 44. In this embodiment, the stop 412 is part of the surface of the interior of the tool roll 411, it is immediately clear to the person skilled in the art that specially provided stops can also be provided for this purpose which are not part of the surface of the interior of the tool roll 411.

Although the stamp carrier 44 has been described in the foregoing as consisting of various parts, it is clear to the person skilled in the art that the stamp carrier 44 is typically a component which has been turned from one piece. In fact, it is also conceivable to assemble the stamp carrier 44 from the individual elements 421, 46, and 47. Moreover, it is not necessary for the pin 47 or the ring 46 to have a cylindrical cross section, since the stamp carrier 44 itself is not rotated during the up and down movement.

With the aid of a suitable tool, the operator can now create different hole patterns 3 by bringing the corresponding stamp carrier 44 into the corresponding active or passive end position and fixing it there to the stops. If the torque used for this limited by a torque wrench, a very high precision and reproducibility of the end position of the stamp 42 can be achieved from the fit between the corresponding stops 51, 412 with the stop surfaces 60, 65 of the stamp carrier 44. This is particularly important for the active end position in order to avoid damage to the dies 42 ′ and to produce high-quality holes 2.

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

If sheet-like printing materials 1 are always processed with the tool roller 41 in such a way 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 roughly corresponds to the dimensions of the smallest-sized sheet-like printing material 1, i.e. in which Generation of a hole pattern LB1, LB2, LB3, LB4, LB5 for wire or plastic comb binding for all formats a hole 2 must be created. It is therefore unnecessary to move the punches 43 from their active end position into a passive end position in this central region 493. Accordingly, the stamp carrier 44 can be dispensed with in the central region 493 in order to reduce costs. Starting from the smallest format, a change in such a hole pattern LB1, LB2, LB3, LB4, LB5 can be achieved in that the punches 42 adjoining the central region in the first and second outer regions 491, 492 also from inside to outside an active position. In principle, however, it is also sufficient to bring only the stamps 42 in the first and second regions 491, 492 into a passive end position, which are in the vicinity of the outer edges K1, K2 of the sheet-like printing material 1. All other stamps 42 can always be in an active end position. This enables the changeover time to be reduced, since when changing the format, only the stamps located in the vicinity of the outer edges K1, K2 of the sheet-like printing material 1 need to be moved, or those which have previously been in the vicinity of the outer edges K1, K2 of the sheet-like printing material 1 lay. In the example shown, a row of 4 stamps is shown in an active end position, the outermost ones are in the passive end position. It is immediately clear from FIG. 1c that in order to generate a corresponding hole pattern LB1, LB2, LB3, LB4, LB5, a considerably larger number of stamps 42, 43 and Stamp carrier 44 is to be provided and that the restriction to six stamps 42, 43 on the Werlczeugwalze 41 was chosen only for illustration purposes.

A corresponding die 42 'is assigned to each punch 42, 43. The die core 43 'represents a passage to the die roller core 411' through which the punching waste can be removed.

As shown in FIG. 4, the die roller 41 'is driven by a motor 402 via a belt pull 403. On the axis of the die roller 41 'is a gear 404 which is connected to another gear 405 which is on the axis of the

Tool roller 41 is attached, is engaged and transmits the rotation of the die roller 41 'in the reverse direction of rotation synchronously to the tool roller 41. Matrix roller 41 'and tool roller 41 are arranged in a housing 401. The tool roller 41 is connected to the motor 402 via a tool shaft 460.

The functional position of the tool shaft 460 is monitored by a sensor 480 and transferred to a higher-level controller 500, which also drives the device by controlling the motor 402. For this purpose, a marking 481 is provided on the tool shaft 460, which makes it possible to determine the functional position of the tool shaft 460, for example in the form of a perforated diaphragm 481. In this case, the sensor 480 is an optical sensor 480 or other coding or a corresponding sensor conceivable to determine the functional position of the tool roller 41.

The device described here for producing different hole patterns in sheet-like printing materials is used in particular in the inline further processing of printed products from digital printing machines. It can also be used in all copiers / printers in which sheet-like substrates are post-processed, in particular also in offline processing. In addition, it is conceivable to also use the stamp carrier for a stand-alone device that introduces a stamping pattern into stacks of sheet-shaped printing materials and that is as flexible as possible should. In such a device, however, the required precision, which would otherwise have to be maintained in rotary two-part (punch / die) tools, and which can be achieved with the tool roller according to the invention, would be lower.
