Description

The The invention relates to a device for generating different Hole pictures in leaf-shaped Substrates, according to the preamble of Claim 1.

In The printing industry has a need for stamping substrates especially in preparation for a binding process, by means of which individually printed sheets to a brochure or a ring-bound book using wire comb or plastic binding together be, or alternatively to the storage of sheet-like substrates z. B. in folders or folders.

Out the numerous devices known from the prior art and method for punching holes in leaf-shaped Substrates form a group of those devices and processes which carry out a flying processing of sheet-shaped substrates. there Under flying processing is meant that the sheet-shaped substrates in the moving state, unlike systems, where several leaf-shaped Substrates in the dormant state z. B. perforated or trimmed become. Typically, during flying processing, the sheet-like substrates individually processed and subsequently collected, whereas in others Procedure the leaf-shaped Substrates first collected and subsequently processed. The flying editing of leaf-shaped In contrast, printing materials has the advantage that this editing better the workflow of a Printing machine for sheet-like substrates corresponds, which typically the sheet-shaped substrates sequentially printed. Therefore, the flying editing for the print finishing offers especially for so-called inline devices to directly to such a printing press, z. B. a digital Printer or copier are connected. The flying processing but is not tied to inline devices, but can also in so-called offline devices, which are not in direct contact with a printing press, advantageous be used.

The Hole patterns in leaf-shaped Substrates are essentially different in the position and the number of holes to be punched. For example, you can distinguish the European 2 or 4 hole hole pattern or the US 2, 3, 4, 5 or 7 hole hole pattern.

It is advantageous to make a punching device as flexible as possible, since the requirements z. B. to the position of the holes or their number of a printing and / or further processing order can change to the next. In the US patent specification US 2,116,391 A discloses a device for flexible adjustment of punching patterns in a punching device. Here individual punches are fixed on axially displaceable sprockets. The sprockets, which are also equipped with a scale, an angular positioning of the punch on the circumference of the sprockets is achieved, the same applies to the positioning of the associated matrices. In the solution proposed above, the punches are screwed individually in their intended position. As a result, a flexible change is possible, but associated with considerable expenditure of time.

In the US patent specification US 5,669,277 A For example, a rotary punching device is proposed in which holders for punches for a multiplicity of different hole combinations are provided in a first shaft. The change between different hole patterns is done by inserting or removing the relevant stamp from the corresponding brackets. As a result, a high precision of the punch positions is achieved. The disadvantage, on the other hand, is that the punches have to be replaced manually for each change of the punching pattern.

In the German Offenlegungsschrift DE 34 27 686 A1 discloses a device in which on a punching ring of a punching device, a number of radially, spaced-apart stamping dies are mounted, which are radially displaceable by means of inner cam rings between a first outer punched position and a retracted passive position. In addition, the punch rings on the shaft can be moved along the axis, so that a large number of different punching patterns can be generated. A disadvantage of the solution described is that the change between the punching patterns is not possible during operation.

In the international application WO 98/55278 A1 A method for changing perforation patterns is proposed in which perforation tools are also brought radially from a passive to an active position and thus lead to a change of the perforation pattern. For this purpose, the perforation tools are resiliently mounted against a hose, wherein the hose helically or doppelhelisch within the tool-carrying roller winds around the roller. Inflating the hose will cause a stroke of the tools into their active position. An advantage of this construction is that a change between the punching patterns is possible here at any time. The disadvantage, however, is the limited number of different punching patterns, which depends on the number of hoses that wind around the tool-carrying roller, as always in a whole hose is inflated.

In the German Offenlegungsschrift DE 28 11 109 A1 there is disclosed a modular construction of a transverse perforating apparatus in which the perforating operations are subdivided, that is, performed by separate rollers, and wherein the pitch of the transverse perforation is controlled by changing the relative position of the rollers with respect to each other. Depending on the number of separate perforating rollers, different perforation patterns can be achieved. The disadvantage here is that a large number of moving parts is required.

In the European patent application EP 1029640 A2 a cross-processing device is disclosed which has two processing units, which lie behind each other and thereby represent two successive processing levels, wherein each one of the processing units can be selected by a controller. In one embodiment, the cross-processing device is constructed from a first synchronous cutter and an immediately adjacent dynamically variable cross-cutter. According to the disclosure, one of the cross cutters can be shut down as long as the other works. The stopped individual cutter forms in this case a passage in which a guide table can be retracted. The optional use of two cross cutters can thereby cut a larger number of different formats. It is also suggested that the same principle can be used instead of cross-cutting for the introduction of different hole patterns.

The DE 34 27 686 A1 discloses a punch for making various hole patterns in a moving paper web. The punch has a punch ring with punches which are slidable between an outer punch position and a retracted position in which they are disengaged from the paper. Within the punching ring are cam rings for controlling the punches. The hole patterns produced by the punches extend in the transport direction of the paper web.

The EP 0 347 087 A2 shows a rotary cutting machine with a camshaft, which is located within a punched tool roll. The stamps, which are used to securely grasp paper strips, are driven by cams of the camshaft.

At the Introduction of punching rows along one Side of a leaf-shaped Substrate for a ring bond, z. B. Drahtkamm- or plastic bond is advantageous if the holes so in the leaf-shaped Substrate are introduced so that the perpendicular thereto Edges of the leaf-shaped Substrate should not be violated. It is therefore desirable a punching device available to make it possible by means of this is and with that as well one possible size available number punched from different hole patterns in sheet-like substrates can be and a change between the different hole patterns fast to carry out is.

It Therefore, the object of the invention is a device for generating to create different hole patterns in sheet-like substrates, with which a generation of a plurality of hole patterns is possible and a change between the hole patterns can be done quickly, easily and inexpensively can.

These Task is using the inventive device for generating of different hole patterns in sheet-like substrates with the solved in claim 1 mentioned features.

In an advantageous embodiment of the device according to the invention the stamps are resiliently mounted and move against the surface of the cams by rotation of the camshaft relative to the tool roll, the cam surfaces assigned stamp in a recessed and unpressed position.

In an advantageous embodiment, the device according to the invention comprises a control and storage means, by means of which the change between the different hole patterns is carried out automatically according to an instruction stored in the storage means. The instruction can be done by the input of an operator when setting up the printing and / or further processing operation or by a controller which determines by means of sensors, which format the incoming sheet-shaped substrate has, and determines which hole pattern is to be introduced into the sheet-like substrate and accordingly, which punches on the tool roll must be brought into a recessed or undeflected position by means of the cams on the camshaft. Also, the instruction on the format of the sheet-shaped substrate and the associated hole pattern of one of the device according to the invention upstream device can be made, which passes the sheet-like substrate of the inventive device. The instruction can also be carried out by a central control unit which coordinates the entire printing and / or further processing operation. In this way, no intervention of an operator to change the hole pattern of the device according to the invention during the run the operation required.

In a further advantageous embodiment of the device according to the invention is the surface the cam sections of a plurality of segmented, to each other subsequent, planar surfaces formed, whereby the surfaces, with where the back of the corresponding stamp is in contact, located within the circumference of the camshaft. The cams outside of the peripheral portion with the segmented planar surfaces the cams a circular arc with a fixed radius, which advantageously just corresponds to the radius of the camshaft. The radius is in In this case, the maximum distance between the points on the individual segmented cam surfaces and the axis of the camshaft. However, the same is a radius the camshaft and / or formed as a circular arc section the cam curve feasible, the minimum between the points on the individual segmented cam surfaces and the axis of the camshaft represents, in such a case, the operating principle would be reversed and the stamps would become be in a recessed position when in contact with the non-segmented circular arc surface the cam in contact.

advantageously, the cam curve is divided into segmented, planar planes, as a result, more stable bases for the Stamp on the camshaft be realized as this with a non-segmented cam surface possible would. In addition is the production of segmented, planar, secant-like recesses in the camshaft particularly simple and inexpensive.

In a further advantageous embodiment of the device according to the invention is the rotation of the tool roll and the camshaft by means of a Coupled freewheel, so that a rotation in one direction the Camshaft and the tool roll moves in the opposite direction Direction, however, only the tool roll is moved. The camshaft Crossed in rotation in the other direction against the housing. Just like that is also a reverse operating principle possible, in which only the Camshaft continues to rotate, while the tool roll remains at rest, about a relative rotation between the camshaft and tool roll to achieve. Due to the freewheel can be particularly advantageous drive the tool roll and the camshaft by means of a single motor and a translation and at the same time the relative angular position between the tool roll and camshaft changed which causes the different functional positions of the camshaft be controlled.

In a rotation direction is used to drive the punching device Introduction of the hole pattern in a continuous sheet-shaped substrate. Around a consistent hole pattern for To grant subsequent substrates, this must be the camshaft move synchronously with the tool roll, resulting in a simple Ensured entrainment of the camshaft with the rotation of the tool roll becomes. By the freewheel, it is possible by reversing the direction of rotation the camshaft relative to the tool roll in a new functional position move. Due to the nature of the camshaft changes thereby the position of at least one or more punches of a submerged position in an undeflected position or vice versa, which leads to a new hole pattern. With renewed reversal of the direction of rotation is by taking along the Camshaft with the tool roller, in the new relative angular position between camshaft and tool roller, introducing the changed Hole pattern in a leaf-shaped Substrate causes.

In a further advantageous embodiment of the device according to the invention is the function position by means of a sensor and a marker the camshaft monitors. The marker is, for example, by a with the Camshaft mitrotierenden perforated disc formed by a optical sensor is evaluated. Also is a magnetic Marking with corresponding sensor conceivable.

In A further advantageous embodiment processes the device according to the invention the leaf-shaped Independent substrates their format such that the centerline of the sheet-like substrates with the center line of the transport path of the sheet-like substrates substantially coincident by the device. This can a symmetrical introduction of a hole pattern in the sheet-shaped substrate guaranteed without the lateral position of the tool and die rollers changed would have to be.

In a particularly advantageous embodiment of the device according to the invention, the punch positions are so positioned on the tool roll, so that the punches have a constant distance from each other along the tool roll. In this embodiment, the punches are provided for producing a hole pattern for a ring bond by means of a plastic or wire comb binding. The hole pattern of sheet-shaped substrates of different format differs in this binding technique essentially by the number of holes that are introduced along one side in the sheet-shaped substrate. This means that a certain number of punches, depending on the smallest format, which should be processable with the device according to the invention, in the hole pattern for ring bonds always to Er generating holes in the sheet-shaped printing material contributes. In the edge region of the sheet-like printing material, on the other hand, it should be avoided that the stamp in question introduces a hole in the edge of the sheet-shaped printing material, since this contributes to an undesirable deterioration of the appearance of a booklet bound by wire comb or plastic elements. The stamps which would violate the edge of the sheet-like printing material or do not have a minimum distance from the edge of the sheet-shaped printing material must therefore be retractable if necessary, in accordance with the format of the sheet-shaped printing material. The minimum distance between the hole and the edge of the sheet is dictated by stability considerations to avoid tearing the holes in the bound booklet.

Therefore has an advantageous embodiment of the device according to the invention a middle area, where in the middle area the punches the tool roll are assigned no cams, and a first outer region the camshaft and a second outer portion of the camshaft, taking the punches in the outer areas the camshaft cams are assigned. The stamp in the middle Area are therefore not retractable. As a result, unnecessary production costs can be avoided become. In the first and second outer regions of the camshaft On the other hand, the stamps associated with these areas can be inserted into Interaction with the cam of the camshaft in a recessed or in a non-lowered position. Seen from the middle area to the outside, have to the punches, which are the cams of the outer areas The camshaft then assigned in an un-lowered position if they are according to the format of the leaf-shaped Substrate at least a minimum distance between the einzubringenden Hole and the edge of the leaf-shaped Have printing material. Next, the stamps have this Minimum distance does not have to be in a recessed condition so that the leaf-shaped Substrate in the range of the minimum distance from the edge of the sheet-like substrate not punched. Outside the edge of the leaf-shaped Substrate is the condition of the stamp, whether sunk or unsealed, indifferent, since the stamp anyway not usually with the sheet-shaped substrate in touch comes.

In an advantageous embodiment of the device according to the invention are therefore the surfaces the cam in the first outer area the camshaft and the second outer area the camshaft arranged so that in the relative rotation the camshaft to the tool roll the punches, the cam of the first outer area the camshaft and the second outer area assigned to the camshaft, in a recessed and in a non-recessed Position, resulting in an uninterrupted series of Unscrewed punches on the tool roll resulting from the middle area of the camshaft in the first outer area of the camshaft and the second outer area the camshaft to the respective innermost recessed punch, the Cam of the outer areas is assigned extends. This uninterrupted series of unbacked Stamping is bounded laterally either by a recessed punch or ends with the utmost Stamp of the respective outer area. Outside the limit of uninterrupted series of unsealed stamps can the possibly remaining stamp in the outer areas in a sunk or unsecured condition. The continuous series of Unscrewed stamps corresponds exactly to the number of holes that depending on format to produce the desired Hole image along the side of the sheet-shaped substrate introduced must become.

In a further education are the areas the cam in the first outer area the camshaft and the second outer area the camshaft is arranged so that by relative rotation the cam surface the camshaft to the tool roll around a segment of the cam surface, the continuous row of unsecured punches on the tool roller shortened by at least one stamp, the uninterrupted row of unsecured punches each limiting, submerged stamp on the tool roller in turn in the first outer area the camshaft and in the second outer area The camshaft will be sunk until the uninterrupted row of unscrewed punches on the tool roll the irreversible punches, which are assigned to the central region of the camshaft corresponds. The punches, which may be before the rotation of the cam surface of the Camshaft to the tool roll around a segment of the cam surface the Limit the continuous row of unsecured stamps on the tool roll represented can then either sunk, or after the rotation of the Cam surface of the camshaft to the tool roll by one or more other segments of the cam surface in one unsecured state to be moved. A setting of the cam surfaces, the a sinking of several punches during rotation around a segment provides, then makes sense, for example, if the processed sheetlike Substrates in this format range only a rough gradation require, for example, the change between a perforation in the longitudinal direction and a perforation along the width of a sheet-shaped substrate of the format A4.

In an advantageous embodiment of the device according to the invention provides an upstream Filing the sheet-like substrate offset from the center line of the transport path of the sheet-like substrates by the device so that the uninterrupted series of unpressed stamp on the tool roll introduces a hole pattern in the sheet-shaped substrate, wherein the distance between the outermost stamp to the corresponding edges of the sheet-shaped printing material is substantially equal. As a result, a symmetrical hole pattern is always generated in the sheet-shaped substrate. This is particularly necessary for either an odd or even number of punches in the continuous row of unweighted punches on the tool roll, depending on how the punches on the tool roll are positioned relative to the center line of the sheet transport path through the apparatus of the invention. For example, in one case, if the innermost punches lie on the centerline of the transport path, an even number of punches in the unbroken row of unpressed punches on the tool roll will require a corresponding lateral offset of the incoming sheet substrate to the centerline of the transport path by an equal distance from the outermost ones Holes that are introduced into the sheet-shaped substrate, to ensure the edges of the sheet-like substrate. By contrast, with an odd number of punches in the uninterrupted row of unweighted punches on the tool roll, a sheet-shaped substrate delivered on the centerline of the transport path in this exemplary case would automatically become a symmetrical hole pattern to the edges of the sheet by placing the punches on the tool roll Lead substrate.

The Shape of the holes depends on it only from the stamps, with rectangular, round or oval holes each possible after application are and within the scope of the invention shown here.

In an alternative embodiment of the device according to the invention are instead of a hole pattern for a ring binding by means of plastic elements or wire comb binding different hole patterns for the filing of the leaf-shaped Substrates in folders or folders are provided. These are the punches on the tool roll and the cam surfaces in such a way positioned on the camshaft so that its position is the US 2 hole hole pattern or the US 3 hole hole pattern or the US 4 hole hole pattern or the US 5 hole hole pattern or the US 7 hole hole pattern or the European 2-hole Hole pattern or the European 4-hole hole pattern corresponds and that a relative rotation of the camshaft to the tool roll a change between at least two of these Hole patterns possible. The European and the US hole patterns differ in addition to their location also by the diameter of the holes.

In 1a and 1b are sheet-like substrates 1 with different hole patterns 3 , E2, E4, US3, US5 shown schematically. In 1a is the hole picture 3 for ring bindings by wire comb binding (so-called Wire-O) or for bonding by means of plastic elements along one side of a sheet-shaped substrate 1 shown. The sheet-shaped substrate 1 has a length L and a width B, wherein the length L is that direction of the sheet-shaped substrate 1 marked along the transport path of the sheet-like substrates through the device 40 runs. The width B indicates here the direction parallel to the hole pattern 3 runs. In this direction, the sheet-shaped printing material on a first entering the device leading edge K3 and an opposite trailing edge K4. The punch holes 2 have a fixed distance B0 and to each other Trailing edge K4 a fixed distance L1.

Further, known to the expert hole combinations are also feasible and are within the scope of the invention shown here. The exact size of the distances of the holes to each other are also known 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 the American hole pattern 8 mm. The reference character M denotes the center line of the sheet-shaped substrates.

The 2 to 7 show different views of a preferred embodiment of the device according to the invention 40 and are limited to the clarity of the presentation of components essential to the invention. Further, generally known and required for operating the device drive and / or guide means and cams as well as electrical circuits are if, then shown only schematically or will be described only in general terms.

As in 2 shown, the die roller 41 ' by means of a motor 402 over a belt train 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 with the tool roll 41 transfers. matrix cylinder 41 ' and tool roll 41 are in a housing 401 arranged. Inside the tool roll 41 there is a camshaft 46 in a direction of rotation of the tool roll 41 is taken, so that the rotation of the camshaft 46 in this direction of rotation of the tool roll 41 exactly corresponds. The entrainment of the camshaft 46 takes place by means of a 3 shown ball catch 471 , which by immersing in it provided on the camshaft in 7 wells shown 472 a stable coupling between the camshaft 46 and tool roll 41 causes.

At the housing 401 is a freewheel 47 attached, the only one direction of rotation of the camshaft 46 allows. When reversing the direction of rotation of the tool roll 41 becomes the camshaft 46 against the case 401 supported, causing a relative rotation of the tool roll 41 to the camshaft 46 comes. In the new functional position of the camshaft 46 locks the ball catch 471 a, allowing a safe entrainment of the camshaft 46 by rotation of the tool roll 41 upon renewed reversal of the direction of rotation of the tool roll 41 is guaranteed.

The functional position of the camshaft 46 is monitored by a sensor and passed to a parent, not shown, known in the art control. For this purpose, a mark is on the camshaft 481 provided, which makes the functional position of the camshaft detectable, such as in the form of a pinhole 481 , In this case, it is the sensor 48 around an optical sensor 48 ,

In 3 is in cross section the internal structure of the tool roll 41 and the die roll 41 ' shown. In this case, it is a stamp assembly in which the stamp 42 have a constant distance to each other. In the case of another hole pattern 3 , E2, E4, US3, US5 are the stamps correspondingly different in the tool roll 41 positioned. Also, a configuration is conceivable in which the stamp 42 for different hole patterns 3 , E2, E4, US3, US5 on opposite sides of the tool roll 41 are attached.

The inner 411 the die roller 41 ' is hollow, so that stamping waste, by itself through the matrices open at the bottom 42 ' inside 411 the die roller 41 ' falls, laterally out of the device 42 in a suitable, not shown, known in the art collecting device is transported.

As in 4a and 4b to see are the stamps 42 in a stamping warehouse 423 slidably mounted. The punch bearing is by means of a screw 422 in the tool roll 41 attached. The screw presses 422 the stamping warehouse 423 to a stop in the tool roll 41 , The stamps 42 are by means of springs 421 against the surface of the camshaft 46 and in particular at least partially against the surface of the cams 461 stored. The geometry of the cams 461 and the cam surface segments 462 are exemplary in 7 shown. Dependent on the functional position of the camshaft 46 become the stamps 42 with its cutting edge over the circumference of the tool roll 41 pushed and dive into contact with the die roller 41 ' into the matrix 42 ' and punch holes 2 in the sheet-shaped substrate 1 The sheet-shaped substrate 1 is during transport through the device according to the invention 40 divided by two baffles 406 guided. The baffles 406 have openings in the area of the punches 42 and an outwardly inclined portion in the region of the inlet of the sheet-shaped substrates 1 into the device 40 on, ensuring a safe transport through the device 40 is guaranteed.

As in 4 and 5 shown, there is the camshaft 46 from a pole, the recessed at certain points, segmented, partially planar cam surface segments 462 having. This can be in this embodiment in the camshaft 46 three areas 491 . 492 . 493 differ. In a middle area 493 are not a cam 461 provided and the camshaft 46 has a continuous circular profile. The stamps 42 in the middle area 493 against the camshaft 46 are sprung, are always in a non-recessed position and therefore contribute to each revolution of the punching roller to the generation of holes. In a first outer area 491 and a second outer area 492 indicates the camshaft 46 in contrast, the cams mentioned 461 on, causing the stamp 42 inside the tool roll 41 sink. The cam surface segments 462 are arranged to each other so that the cam surface segments 462 with which the stamp 42 in a functional position of the camshaft 46 Having contact, along the camshaft 46 have the same angular position. The number of possible functional positions of the camshaft 46 is by the number of latching possibilities in the ball detent recess 472 the ball catch 471 given. In the embodiment illustrated here, these are six latching possibilities, in a preferred embodiment, a larger number of latching possibilities of the camshaft 46 provided so that all stamp 42 that the outer areas 491 . 492 are assigned, are selectively retractable and thus a large number of different formats of the sheet-shaped substrates 1 is possible.

In the basic position of the camshaft 46 relative to the tool roll 41 are all stamps 42 in unsecured position, so that the number of holes in a through the device according to the invention 41 transported sheet-shaped substrate just the maximum number of stamps 42 on the tool roll 41 corresponds to exactly twenty-four in this embodiment.

The surfaces of the cam surface segments 462 are so along the camshaft 46 arranged so that upon relative rotation of the camshaft 46 around a cam surface segment 462 the outermost stamp 42 the first outer portion of the camshaft 491 sunk. This will make up the remaining set of un-stamped punches 42 around a stamp 42 shortened, in this case to exactly twenty-three. To a symmetrical hole pattern in a supplied sheet-shaped substrate 1 To achieve, now has a higher-level control, not shown, the following sheet-shaped substrate 1 from the center line of the transport path of the sheet-shaped substrates 1 by the device according to the invention 40 Request offset, such that the distances B1, B2 of the two outermost punches 42 the continuous row of unsecured stamps 42 that are from the middle range 493 the camshaft 46 in the outer areas 492 . 493 the camshaft 46 extends, to the edges K1, K2 of the sheet-shaped substrate 1 are the same.

The surfaces of the cam surface segments 462 continue to be along the camshaft 46 arranged that upon further relative rotation of the camshaft 46 around a cam surface segment 462 the outermost stamp 42 the second outer portion of the camshaft 492 sunk, and the outermost stamp 42 the first outer portion of the camshaft 491 sunk. This will make the remaining uninterrupted row of un-stamped punches 42 for another stamp 42 shortened, in this case to twenty-two stamps. At a further relative rotation of the camshaft 46 around a cam surface segment 462 will now be mutually always the next inner stamp 42 in the outer areas 491 . 492 sunk, leaving the remaining uninterrupted row of un-stamped punches 42 always another stamp 42 that are from the middle range 493 the camshaft 46 in the outer areas 492 . 493 the camshaft 46 extends, shortened until the remaining uninterrupted row of unsecured punches 42 on the number of non-retractable stamps 42 in the middle area 493 has reduced, preferably to ten punches 42 , The position of the stamp 42 in the outer areas 491 . 492 the camshaft, which is outside the continuous row of unsecured punches 42 lie and not limit, is arbitrary, the stamp can thus be here either in a recessed or unentered position.

The Device described here for Generation of different hole patterns in sheet-shaped substrates finds particular application in the inline finishing of Printed products of digital printing machines. One use in all Copiers / printers in which sheet-shaped substrates are reworked be, is also possible in particular also a use in the offline further processing.
