Description

  The present invention relates to an apparatus for punching, grooving or punching with a rotary printing press, in particular a multicolor rotary printing press, as defined in the premise of claim 1.

  A device of this kind for punching, grooving or punching on a rotary printing press is known from EP 1068077B1 of US Pat. The apparatus comprises at least one printing and coating unit with a blanket cylinder formed by two clamping shafts and an opposing impression cylinder associated with the blanket cylinder. Further, the blanket cylinder is provided with a cylinder groove for accommodating the fastening shaft. Instead of the blanket, a substrate made of a flexible and dimensionally stable material is fixed to the blanket cylinder, and is placed on the positioning coupling surface with a thin base sheet stretched on the substrate. A processing pattern raised as a drilling / grooving / punching pattern according to a predetermined drilling / grooving / punching shape can be mounted on the base sheet, and can be particularly applied. For mounting or fixing the base sheet, the substrate is provided with holding rails corresponding to the holding rails of the blanket in the circumferentially opposed end regions of the associated blanket cylinder so that the substrate is connected to the blanket using a clamping shaft. Similarly, it is held on the blanket cylinder. A mounting frame that is spaced from the holding rail associated with the clamping shaft on the end side and that is spaced in the circumferential direction of the associated blanket cylinder is similarly attached to the substrate, and the opposite end of the base sheet is mounted on the mounting frame. It is attached so that it can be relaxed in a state where the partial area is stretched. By mounting the base sheet in such a relaxed manner on the substrate fixedly mounted on the blanket cylinder, the relative position between the substrate and the base sheet is corrected without changing the shape mounted on the base sheet. And thus a position correction with respect to the processed sheet can also be carried out. The mounting frame can be moved within the adjustment range with respect to the substrate and can be fixed again, so that the position correction of the base sheet with the processing pattern attached to the correct shape can be performed quickly and easily on the substrate. it can. Therefore, the mounting frame of the base sheet is arranged so as to rise on the outer peripheral surface of the blanket cylinder so equipped and can be freely accessed. With such a device, drilling, grooving and punching shapes can be easily and easily attached to the base sheet outside the machine, and the base sheet itself can be easily fixed to the board using the mounting frame. Can do. Thus, base sheets fitted with drilling, grooving and punching dies can be replaced quickly and easily, once assembled base sheets can be stored, thus providing equipment for periodic use, for example. You can use it again without replacing it with a new one.

EP1068077B1

  It is an object of the present invention to assemble a device more easily when improving functional safety in a device of the type that performs punching, grooving or punching with a rotary printing press, and in addition to this, the drilling, grooving or punching operation is simplified. The further development is to implement with high quality.

  This problem is solved by the features described in claim 1.

  According to claim 1, a processing pattern raised as a drilling / grooving / punching pattern according to a predetermined drilling / grooving / punching shape is mounted on the base sheet, and is particularly affixed. It is similarly fixed to the formed blanket holding device.

  Thus, advantageously, the existing blanket holding device is used here for the dual function for holding the base sheet. Both the base sheet and the normally existing substrate can be fixed to the holding device or the clamping device according to the invention. Thus, advantageously, this ensures that all fixing or holding devices for the base sheet or possibly the existing substrate are accommodated approximately in the region of the body groove and this region is usually re-used using the existing body groove cover. Can be covered. As a result, work safety is enhanced first, and at the same time, many places are provided freely as viewed in the circumferential direction of the blanket cylinder, and a processing pattern is freely mounted thereon. In other words, it can be confirmed by a simple method that there is no raised structure part except for the processing pattern in the outer periphery of the cylinder or the area outside the cylinder cover, so that damage is caused from another adjacent cylinder such as a plate cylinder. Can be prevented. In this way, by integrating the base sheet and the holding device in the region of the cylinder groove according to the invention, it is possible to achieve quick and easy arrangement or alignment of the base sheet and / or the substrate in the blanket cylinder without changing, As a result, an inline finishing system that is improved and further developed as an apparatus for drilling, grooving or punching on a printing press is freely provided.

  In particular, according to an advantageous embodiment according to claim 2, the base sheet position correcting means can be used without changing the working pattern mounted on the base sheet or removing the base sheet from the blanket cylinder, i.e. correcting the position of the base sheet. The means is performed in a state of being sandwiched between the substrate and the blanket cylinder. Claim 3 relates to the preferred use of the base sheet together with the substrate.

  A mounting frame as defined in claim 4, preferably extending in the axial direction of the cylinder, allows a simple, reliable and quick mounting of the base plate to the holding device forming the blanket holding device. In addition, a different way of correcting the position of a base sheet with a working pattern already attached and tightened in the correct shape is realized in a simple manner using such a mounting frame. This will be described in detail later. Depending on the specific mounting conditions, the adjustment range is given in advance, for example, only in the circumferential direction of the blanket cylinder or in the circumferential direction and the axial direction, as will also apply to the method described in detail later. However, for general use of the invention, adjustment methods in all space directions, in particular diagonal directions, are preferred. In this case, the predetermined adjustment range is preferably 5 mm in any space direction, and most preferably 1.5 mm.

  According to a first variant of claim 5, the mounting frame is fixed and arranged on the holding device so that it cannot move. In that case, the mounting frame is formed integrally with the holding device or as a separate component, in which case it is fixed, for example, by screw connection. Similarly, a holding frame or an area functioning as a holding frame is attached to the end region of the base sheet, which is formed of components that are integrated or separated, so that the base sheet can be moved within a predetermined adjustment range, and is again related. It is fixed and held on at least one of the mounting frames.

  In that case, the holding frame on the base sheet side is attached to each associated mounting frame using at least a relaxable bond according to a specific embodiment. The relaxable bond is freed of relative movement of the base sheet when the bond is loosened, while the base sheet is fixed to the blanket cylinder when the bond is fixed, in particular, pinched and held. For this purpose, the mounting frame according to claim 7 is provided with a specific plug-shaped mounting frame / adjustment pin, and a predetermined oversize is formed with respect to the adjustment pin in the holding frame of the base sheet, for example, a long hole is formed. Relevant base sheet recesses. The adjustment pin recess is selected here so that a predetermined desired adjustment range is given in advance for position correction. According to a particularly preferred embodiment of the present invention, a clamping frame is further provided that is sandwiched between the mounting frame and the holding frame on the base sheet side.

  In the embodiments described above, the mounting frames are each arranged in a holding device so that they cannot be moved in a fixed manner, but according to a particularly preferred embodiment according to claim 9, as an alternative, they are formed with separate components In order to correct the position relative to the mounted frame, it is stated that at least one of the mounting frames can be moved within a predetermined adjustment range relative to the holding device and can be fixed to the holding device again after the movement. Has been. According to an advantageous, easy to manufacture, functional and specific embodiment, the mounting frame according to claim 10 is fixed to the holding device using at least one relaxable connection, in particular a screw connection. According to a specific form, the relaxable connection is formed by a recess on the mounting frame side that is oversized with respect to the screw shaft of a fixed or set screw that can be screwed into a holding device or a clamping shaft and is formed as a head screw. It is preferable.

  In the case of this adjustable mounting frame, the base sheet can be loosely fixed and joined to the mounting frame according to claim 11, in particular via a mounting frame / adjustment pin and a base sheet recess with which the shape can be fixed. The When a large number of base sheets are stored, base sheet recesses that are identically arranged and formed in the same manner are provided on the base sheet.

  Similarly, in the sense of combining the two basic position adjusting means described so far according to claims 5 and 9, for the adjusting means, on the one hand, between the holding device and the mounting frame, on the other hand, Between the mounting frame and the base sheet, a holding frame formed as an integral or separated structural part in the end region of the base sheet or an area formed in the holding frame is arranged as described in claim 12. Using this, the base sheet is movable within a predetermined adjustment range, and is fixed again after the movement and held in at least one of the related mounting frames. For example, this can be done by an over-recess on the side of the base sheet, for example by means of a plug-like adjustment pin arranged on the mounting frame in relation to the elongated holes aligned in the axial direction of the cylinder, and using the adjustment pin, The position correction can be performed in the axial direction, while the mounting frame can be used to correct the position of the cylinder in the circumferential direction, for example. In this case as well, the base sheet can be fixed again using the sandwiching frame, and the base sheet is fixed and sandwiched between the two frames by using it. The attachment of the clamping frame to each associated mounting frame is preferably performed using screws screwed directly into the respective mounting frame or holding frame and suitable set screws.

  According to claim 13, the holding device is usually formed as a structural part formed in the holding device or the blanket holding device by means of two clamping shafts which are accommodated in the body groove and which are spaced apart from each other, and according to claim 14, respectively. Are preferably related. The clamping shaft is preferably provided with a cutting surface or a cutting plane in order to allow a positioning coupling surface for each mounting frame. The clamping shaft is adjusted so that it can rotate to a desired value, in particular 360 °.

  According to claim 15, the blanket cylinder is provided with a cylinder groove cover, which is used to cover the cylinder groove at least regionally in the assembled state. This measure is useful for work safety and accident avoidance.

  The base sheet itself is produced from a flexible and dimensionally stable material according to claim 16, for example as a rectangular base sheet, in which case plastics can be used. Such a plastic sheet can have a strength of, for example, about 0.18 mm. An orthogonal grid line array is provided as a measurement grid on the base sheet itself. In particular, the grid lines are arranged 1 mm apart from each other in the axial direction of the associated blanket cylinder. The grid lines are likewise arranged at the same line spacing in the circumferential direction of the associated blanket cylinder, but in this case is slightly smaller than 1 mm. In this small line interval, when the base sheet is stretched in a cylindrical shape, the outer contour of the processing pattern that is raised and pasted has a body diameter larger than the outer surface of the base sheet. This difference does not yet appear when the processing pattern is applied with the base sheet as a flat surface. Furthermore, in the case of the above-described line spacing reduction, machine-specific and sheet-specific conditions are taken into account in addition to the cylinder diameter differences and protrusions that can be calculated on the plane grid line arrangement.

  The substrate is also preferably made of a rectangular or rigid plastic plate, in which case the substrate is provided with holding means corresponding to the holding means of the blanket cylinder in the circumferentially opposed end regions of the blanket cylinder, so that The substrate is very simply fixed to the blanket cylinder using a blanket holder in response to the blanket. In some cases, the substrate needs to be lined with a base sheet that is at least calibrated by known methods.

  As the processing pattern, an adhesive treatment band that can be accurately applied to the base sheet outside the printing machine, for example, a cutting / grooving / drilling line or a magnetic punched thin plate is suitable.

  In order to avoid damage to the counter pressure cylinder associated with the blanket cylinder, the blanket cylinder can also be provided with a protective sheet, for example an adhesive counter pressure protection sheet. Alternatively, for example, as described in detail in EP1068077B1 of Patent Document 1, use of a processing pattern including a plurality of portions is also conceivable.

  With the configuration according to the invention, the base sheet is fixed or stretched to the blanket cylinder in a simple manner without being influenced by the substrate. Even when the base sheet is stretched, the base sheet can be adjusted to a precise position, particularly horizontally, vertically and diagonally.

  Hereinafter, the invention will be described in detail with reference to the drawings.

1 is a schematic view of a printing / coating unit of a multicolor rotary printing press. 1 shows a schematic enlarged view of a blanket cylinder having a clamping shaft and mounting device according to the invention for a base sheet. 1 schematically shows a mounting frame that can be removably fixed to a clamping shaft, can be moved, and can be fixed in its position again. 4 schematically shows another embodiment of the recess shape of the mounting frame according to FIG. 3. 1 schematically shows a plug formed integrally with a clamping shaft. The side view of the base sheet fitted to the attachment frame is shown schematically. Fig. 5 shows an enlarged detail view of the base sheet fit-in coupling of the mounting frame according to Fig. 4; Fig. 4b schematically shows an alternative embodiment to Fig. 4a. Fig. 4 schematically shows an alternative embodiment according to Fig. 4a and Fig. 4b. The top view of the expand | deployed base sheet is shown schematically.

  FIG. 1 schematically shows a conventional printing / coating unit 2 of a multicolor rotary printing press 1 including a plurality of printing / coating units, for example. The printing / coating unit 2 includes a plate cylinder 5, and the ink 8 is transferred to a blanket (not shown in detail) of the blanket cylinder 3 through the plate cylinder in accordance with the passage of ink of a printed image. The blanket cylinder 3 is provided with a cylinder groove 13 as a recess on the cylinder peripheral surface, and the fastening shafts 11 and 12 are accommodated in the groove as a holding device for the blanket. The body groove 13 is covered with a body groove cover 14 detachably attached to the blanket cylinder 3 in order to avoid approach. The printed image is transferred via a blanket cylinder 3 onto a printing sheet (not shown) stretched on the counter impression cylinder 4. The printing sheet is conveyed to the area of the counter impression cylinder 4 via the sheet feeding cylinder 6 in the printing / coating unit 2 and is gripped by a paper gripper 9 disposed on the counter impression cylinder 4. The sheet is thereby printed in connection with the device with a further rotation of the counter impression cylinder 4. After the printing of the sheet, the paper gripper 9 releases the sheet again, so that the sheet is carried out via the sheet conveying cylinder 7.

  Such a printing / coating unit 2 is formed in an apparatus according to the invention for punching, grooving or punching, in order to punch, grooving or punching sheets. Therefore, as schematically shown in FIG. 2 as an example, a solid plastic plate having a rectangular surface indicated by a dotted line is stretched as a substrate 10 on the blanket cylinder 3 of the printing / coating unit 2 instead of the conventional blanket. Although not shown in detail here, this substrate 10 is provided with retaining rails corresponding to that of each printing press type blanket in the circumferentially opposed end regions of the associated blanket cylinder 3. Thereby, the substrate 10 is stretched on the blanket cylinder 3 as quickly and simply as the blanket using the clamping shafts 11 and 12 arranged on the blanket cylinder 3.

  Further, as can be seen from FIG. 2, the fastening shafts 11 and 12 are accommodated in the body groove 13 of the blanket cylinder 3 extending in the axial direction or the longitudinal direction of the entire blanket cylinder 3. The body groove 13 is covered with a body groove cover 14.

  As can be seen most schematically in FIG. 2, a base sheet and holding device 60 is further arranged on the clamping shafts 11 and 12 at a distance from the blanket and mounting device 61, and using this device, the base sheet 18 is a base sheet. Is fixed to the blanket cylinder 3 so as to be placed on the substrate 10 at the positioning coupling surface in the tensioned assembly state.

  The base sheet holding device 60 is provided with mounting frames 62 and 63 which are spaced apart in the circumferential direction of the related blanket cylinder 3, and by using this, the base sheet 18 is tightened to the clamping shafts 11 and 12 in the opposite end regions. It is attached.

  Two mounting frames 62 and 63, one of which is schematically illustrated in FIG. 3, are movable and fixed in position within a predetermined adjustment range with respect to the clamping shafts 11 and 12, respectively. For this purpose, the mounting frames 62 and 63 are provided with a plurality of screw / elongate hole connections 64. For this purpose, specifically, a set screw 66 guided by a long hole 65 on the frame side indicated by a cut line is screwed into, for example, a flattened tightening shaft region having a corresponding screw bore (not shown), As a result, when the set screw 66 is pulled, the relative positions of the mounting frames 62 and 63 with respect to the respective fastening shafts 11 and 12 cannot be adjusted. On the other hand, when the set screw 66 is loosened, the relative position adjustment of the mounting frames 62 and 63 and thus the relative position adjustment of the base sheet 18 attached to the mounting frame with respect to the fastening shafts 11 and 12 is the correction of the position of the base sheet 18. Therefore, it becomes free in the circumferential direction of the blanket cylinder 3. The elongated hole shape or oversized shape is described here as an example only, but any shape is conceivable and is suggested and drawn in broken lines in connection with the elongated hole 65 showing the structure according to FIG. 3a. The screw shaft portion 66a is drawn here as a black dot, while the screw head portion 66b is indicated by a broken line. This will be further described later.

  As can be seen in FIG. 2, in the illustrated embodiment, the mounting frames 62 and 63 are mounted on the clamping shafts 11 and 12, respectively, in the positioning coupling plane. The clamping shafts 11, 12, like the mounting frames 62, 63, preferably extend substantially over the entire axial length as viewed in the axial direction of the blanket cylinder 3 in order to form a robust and functionally reliable positioning coupling surface.

  In the example shown here, the base sheet 18 can be moved and fixed to the mounting frames 62 and 63 so that it can be fixed again. For this purpose, the mounting frames 62 and 63 are provided with plug-like mounting frames and adjusting pins 67, as can be seen in particular in FIG. 4, in which the base sheet 18 has base sheet recesses or punched holes formed in the opposite end regions. 68 (FIG. 5) can be used with the position fixed in the circumferential direction. The punching hole 68 is preferably formed integrally with the base sheet 18 and forms a holding frame showing an outline of the elongated hole when viewed in the axial direction. As a result, the base sheet 18 can be moved in the axial direction of the blanket cylinder 3 in order to correct the position of the base sheet 18 within a predetermined adjustment range by the elongated hole shape using the punched hole 68. Details of this position correcting means are shown in FIG. 4a. Here again, the shape of the long hole or the excessive shape is displayed again as an example, but the shape may be any shape, and can be moved both in the axial direction and in the circumferential direction, for example, as shown in FIG. 4b. The shape of the mold recess 70 can also be used. Furthermore, the holding frame may be formed by separate structural parts, for example, it may be permanently fixed and coupled to the respective associated base sheet and end regions.

  As merely schematically illustrated in FIG. 4, the base sheet 18 can be fixed in the axial direction by, for example, a sandwiching frame 69. The sandwiching frame 69 is screwed into the associated mounting frames 62 and 63 or the associated fastening shafts 11 and 12 penetrating therethrough. As a result, the sandwiching frame 69 is sandwiched between the sandwiching frame and the mounting frame. The base sheet 18 is securely fixed and pinched between 62 or 63 so as not to move.

  Reference numeral 71 in FIG. 5 further represents the grid line arrangement described in the previous general description.

  The embodiment described here relates to the relative adjustment means both between the mounting frames 62 and 63 and the clamping shafts 11 and 12 and between the mounting frames 62 and 63 and the base sheet / end region forming the holding frame 68. To do. Instead of this, it is possible to use only one of the relative adjustment means by moving the mounting frames 62 and 63 relative to the fastening shafts 11 and 12. In this case, the base sheet 18 can be securely fixed to the mounting frames 62 and 63 without adjusting, for example, through the hole recess 72 of FIG. Due to a plurality of relative adjustment means in the gap direction, a corresponding elongated hole is formed between the mounting frames 62 and 63 and the fastening shafts 11 and 12, for example, a cross-shaped or star-shaped recess of the mounting frames 62 and 63. The set screw 66 is penetrated and gripped through the shape. As a result, the relative movement of the respective mounting frames 62 or 63 is free in the loosened state, and in the fixed state, the mounting frames 62 and 63 and thus the base sheet 18 are shown in FIG. It is fixed as shown schematically in 3a.

  The same applies to the adjustment means of the base sheet 18 for the recess 68 of the base sheet 18. In this case, the mounting frames 62 and 63 are also formed integrally with the fastening shafts 12 and 13 simply by a stopper 67 on the fastening shaft side, as schematically shown in FIG. Although not shown here, the plug 67 may be a mounting frame or a screw pin or a component screwed into the plug frame that is fixedly fixed to the clamping shaft 12 so as not to move. For adjustment, the base sheet and end region forming the holding frame 68 is provided with an oversized hole recess, for example with respect to the plug 67, so that the base sheet 18 is schematically illustrated as shown in FIG. 4b. Can be adjusted in the desired direction. In order to fix the position of the base sheet 18 whose position has been corrected, a clamping frame in the sense of the clamping frame 69 can be used, and the base sheet can be clamped between the base sheet and the associated mounting frames 62 and 63, respectively.
