Description

Technical Field

[0001] The present invention relates to a mounting device for mounting a tool plate in a flatbed die-cutting, stripping or blanking machine, and also to a mounting assembly comprising the mounting device. Background Art

[0002] A flatbed die cutter, flatbed stripper or part separator may be part of a production line that processes paper, paperboard, corrugated board or plastic, particularly for packaging. For example, multiple blanks on the same sheet are die cut and subsequently separated in a flatbed die cutter using an adjacent flatbed stripper device.

[0003] In order to be able to process different packages, replaceable tool plates are installed in the respective machines, which are specific to the type of package to be processed. For flatbed die-cutters, these tool plates can be, for example, pressure plates with cutting knives or pressure pads attached thereto. The tool plates are usually inserted into the machine from the side with respect to the workpiece transport direction. The tool plates can also be so-called universal tools.

[0004] It is important that the machine works with very high precision. Therefore, the replaceable tool plate must be precisely aligned with the cutting edge of the previous station and held in a stable position to maintain precise alignment. If upper and lower tool changes are provided as in die-cutting or stripping machines, these tools also need to be precisely aligned with each other.

[0005] In order to install replaceable tool plates in flatbed die cutting, stripping or blanking machines, these machines usually include clamping and adjustment mechanisms. However, the known mechanisms are usually complex, include a large number of parts and are therefore expensive in terms of material input and installation time. Summary of the invention

[0006] It is therefore an object of the present invention to provide a mounting assembly for a flatbed die cutting, stripping or blanking machine that is cost effective and easy to assemble.

[0007] This object is achieved by a mounting device for mounting a tool plate in a flatbed die-cutting, stripping or blanking machine, the mounting device comprising at least: at least one first jaw, which can be moved from an unlocked position to a locked position, in which the tool plate can be removed from the machine or inserted into the machine, and in which the tool plate can be fixed in the machine; at least one actuator, which includes a movable piston and a piston rod coupled to the piston, wherein the actuator is configured to transfer at least one first jaw from the locked position to the unlocked position, and wherein the actuator is coupled to at least one first jaw via an attachment point having a fixed position relative to the first jaw.

[0008] By coupling the actuator to at least one clamping jaw via an attachment point having a fixed position relative to the clamping jaw, the assembly of the mounting device is particularly simple and requires only the handling of a small number of individual parts. In contrast to previous mounting devices, there are no gears connecting the actuator and the clamping jaw. This means that, after the mounting device has been assembled, the position of the actuator relative to the clamping jaw is fixed and cannot be adjusted. This allows the production costs to be kept low and the mounting device can be assembled quickly.

[0009] Preferably, the attachment point is arranged directly at the jaw or at a coupling element fixed to the jaw, i.e. the actuator can be coupled to the jaw directly or via a coupling element. If necessary, the coupling element can be a distance piece for overcoming the gap between the actuator and the jaw.

[0010] When the actuator is actuated, its length may increase compared to its length in the non-actuated state.

[0011] According to one embodiment, the actuator is coupled to the first jaw via a swivel joint. Due to the swivel joint, the actuator can be buckled out to overcome geometric and positional tolerances.

[0012] The axis of rotation of the swivel joint may be transverse to the direction of movement of the clamping jaws.

[0013] The mounting device comprises, for example, at least one closing spring, which is arranged in such a way as to move the first clamping jaw towards its locking position. As a result, the mounting device can be operated particularly energy-efficiently. In particular, when the actuator is not actuated, the clamping jaw can be reliably held in the locking position by the closing spring. Therefore, it is not necessary to provide electrical energy to hold the first clamping jaw in its locking position.

[0014] When the tool plate needs to be replaced, the actuator only needs to be actuated for a short time to move the first jaw from the locked position to the unlocked position.

[0015] For example, the closing spring is compressed when the actuator is actuated, thereby storing elastic energy that can be used to move the first jaw from the unlocked position to the locked position.

[0016] According to one embodiment, the closing spring is clamped between a first abutment surface at the piston rod and a second abutment surface having a fixed position in the mounting device. Thus, the closing spring is held in a defined position. Since the first abutment surface is composed of the piston rod, a compact design is achieved.

[0017] The closing spring can be arranged coaxially with the piston rod, and in particular surrounds the piston rod.Therefore, the piston rod serves as a guide for the closing spring so that the spring does not bend when being compressed by the actuator.

[0018] The mounting device has, for example, a linear guide for supporting and moving the clamping jaws. The clamping jaws are thus moved with high precision.

[0019] In particular, the clamping jaw comprises at least one guide portion made of sheet metal, wherein the actuator is coupled to the guide portion. Sheet metal parts can be produced very easily and cheaply. By using sheet metal parts, the overall cost of mounting the device can be particularly low.

[0020] According to one embodiment, the guide portion has at least one elongated slit extending in the direction of movement of the jaws, and wherein the mounting device has at least one protrusion extending through the slit and thereby guiding the jaws. Thus, a simple and effective linear guide is provided.

[0021] In order to provide a particularly stable mounting for the tool plate, the mounting device may further comprise a clamping profile which is fastened to the clamping jaw and is configured to engage the tool plate. The clamping jaw thus does not engage directly with the tool plate. The profile allows the clamping force exerted by the clamping jaw to be distributed more evenly over the tool plate, so that the tool plate is held particularly stably in its mounted position.

[0022] The clamping profile preferably engages the tool plate along its entire length.

[0023] For example, the clamping jaws and the clamping contour are connected to one another by screwing, welding or the like.

[0024] However, according to an alternative embodiment, the clamping profile may be omitted and the clamping jaws may directly engage the tool plate.

[0025] According to one embodiment, the mounting device comprises at least one second clamping jaw, which forms a counter-bearing for at least one first clamping jaw, wherein the first clamping jaw and the second clamping jaw are configured to clamp the tool plate between each other, in particular directly or via a clamping contour. This also contributes to stably holding the tool plate in its mounted position. In particular, due to the second clamping jaw forming the counter-bearing, a sufficient holding force is exerted on the tool plate to prevent an undesired movement of the tool plate during operation of the machine.

[0026] Preferably, the first clamping jaw and the second clamping jaw are present in duplicate in order to provide adequate support for the tool plate.

[0027] In this case, a clamping contour connects the two first clamping jaws and another clamping contour connects the two second clamping jaws.

[0028] The actuator may be fixed to the second jaw directly or via a coupling element. Thus, since the actuator is coupled to the first jaw and fixed to the second jaw, the distance between the first jaw and the second jaw increases due to actuation of the actuator in order to insert the tool plate into the mounting device. Thus, a simple opening mechanism for the mounting device is provided.

[0029] The mounting device may further comprise at least one adjusting device, which is configured to adjust the position of the tool plate in the machine. Thus, the position of the tool plate can be fine-tuned with high precision.

[0030] For example, the adjustment device comprises a setting screw which can be operated by a user to adjust the position of the tool plate. Thus, the operation of the adjustment device is very simple.

[0031] In particular, by means of the adjustment device, the at least one second jaw can be moved in the direction of movement of the jaw. Preferably, the displacement of the second jaw is a linear displacement. The direction of movement of the jaw thus corresponds to the direction of travel of the plate. By means of the displacement of the at least one second jaw, the position of the tool plate in the machine is changed.

[0032] According to one embodiment, at least one bridge having opposite ends is provided, wherein a first clamping jaw is movably mounted to a first end of the bridge and a second clamping jaw is movably mounted to an opposite second end of the bridge. Thus, the bridge serves as a mounting for the clamping jaws and additionally provides sufficient stability for the mounting device. In particular, the bridge extends from one side of the mounting device to an opposite side of the mounting device.

[0033] The object is also achieved by a mounting assembly comprising a mounting device as described above and a frame and / or a tool plate, the tool plate being removably mountable in the mounting device by means of at least one first clamping jaw, wherein the tool plate is attachable to the frame. The frame serves as an adapter for tool plates of different sizes. This allows keeping the mounting device particularly simple, since there is no need to provide complex adjustment means which allow the mounting device to be adjusted to tool plates of different sizes.

[0034] A tool plate having a size suitable for the mounting device can be mounted directly in the mounting device and fixed by means of the clamping jaws. In this case, no frame is required. If the tool plate is smaller or larger than the size that fits into the mounting device, the frame can be releasably attached to the tool plate, for example by means of a screw connection, and the frame can be mounted in the mounting device together with the attached tool plate. In this case, the frame is clamped in the mounting device instead of the tool plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Figure 1 and Figure 2 A longitudinal section through a mounting assembly 10 according to the invention is respectively shown.

[0049] The mounting assembly 10 includes a mounting device 12 for mounting a tool plate 14 in a flatbed die cutting, stripping or blanking machine. Figure 1 In FIG. 1 , the mounting device 12 is shown in a locked state, while in FIG. Figure 2 The mounted device is shown in an unlocked state.

[0050] The mounting device 12 may hold a tool plate 14 or a tool plate 14 and a frame 16, wherein the frame 16 is attached to the tool plate 14 and serves as an adapter for mounting the tool plate 14 in the mounting device 12, because Figure 1 The tool plate 14 shown in FIG. 1 is too wide to fit into the mounting device 12. In particular, by means of the frame 16, tool plates 14 of different sizes can be mounted in a flatbed die cutting, stripping or blanking machine.

[0051] However, if the tool plate 14 is of the correct size, it may be mounted in the mounting device 12 without the frame 16 .

[0052] Next, we will refer to Figures 1 to 10 Further describing the installation device 12, wherein Figures 3 to 10 The mounting device is shown in more detail in different views.

[0053] The mounting device 12 comprises at least one actuator 18 for switching the mounting device 12 from the locked state to the unlocked state and at least one closing spring 20 which holds the mounting device 12 in the locked state when the actuator 18 is not actuated.

[0054] A bearing 21 is provided for guiding the actuator 18. In the embodiment shown, the bearing 21 comprises two guide elements 22.

[0055] Furthermore, in order to allow fine adjustment of the tool plate 14 in a flatbed die cutting, stripping or blanking machine, the mounting device 12 includes at least one adjustment device 24 (see Figure 1 and Figure 2 ).

[0056] Furthermore, the mounting device 12 comprises a centering device 26 which is configured to center the tool plate 14 in the machine (see Figures 3 to 6 ).

[0057] The mounting device 12 comprises two C-shaped beams 25 having a central bridge 28 and arms 29 at opposite ends of the bridge, the arms 29 projecting downwardly and carrying clamping profiles 50. Between the clamping profiles 50 the plate 14 can be clamped.

[0058] In the embodiment shown, each bridge 28 comprises two identical sheet metal parts 30. The sheet metal parts 30 may be fixed to each other by screws, rivets or the like. In addition, each bridge 28 is provided with at least two washers 27. Each bridge 28 has opposite ends 32,34.

[0059] An actuator 18 and a closing spring 20 are provided for each bridge 28 .

[0060] A crossbar 36 connects the bridge 28 at one side of the bridge 28. By means of the crossbar 36, the mounting device 12 can be fixed in a flatbed die-cutting, stripping or blanking machine, for example by screwing.

[0061] The bridge 28 and the crossbar 36 and the corresponding clamping profile 50 are preferably aligned vertically with respect to one another.

[0062] The arms 29 are defined by jaws. A first jaw 38 and a second jaw 40 are mounted on each bridge 28. The second jaw 40 constitutes a counter-bearing for the first jaw 38.

[0063] A first jaw 38 is movably mounted to the first end 32 of the bridge 28 and a second jaw 40 is movably mounted to the opposing second end 34 of the bridge 28. Thus, the first jaw 38 and the second jaw 40 are configured to clamp the tool plate 14 or frame 16 between each other.

[0064] The first jaw 38 is movable from an unlocked position, in which the tool plate 14 and the frame 16 can be removed from or inserted into the machine, to a locked position, in which the tool plate 14 or the frame 16 can be secured in the machine.

[0065] In particular, the actuator 18 is configured to transition the at least one first jaw 38 from a locked position to an unlocked position.

[0066] The second clamping jaw 40 can also be moved, only for fine adjustment. However, the clamping jaw 40 is not actuated by the actuator 18.

[0067] For example, each jaw 38, 40 may move approximately 5 mm to 10 mm in the moving direction.

[0068] The mounting apparatus 12 also includes a linear guide 42 for supporting and moving the jaws 38 , 40 .

[0069] As in Figure 1 and Figure 2 As can be best seen in FIG. 4 , each jaw 38 , 40 comprises a guide portion 44 made of sheet metal, in particular of two sheet metal parts that are preferably identical to each other. However, other materials are also possible.

[0070] Each guide portion 44 has two elongated slits 46 which extend in the direction of movement of the clamping jaws 38 , 40 .

[0071] The mounting device 12 has a plurality of protrusions 48 which extend through the slots 46 and thereby guide the jaws 38, 40. In the embodiment shown, the protrusions 48 are rectangular parallelepiped blocks fixed to the bridge 28.

[0072] The guide portion 44 with the slit 46 and the protrusion 48 together form the linear guide 42 .

[0073] Furthermore, a clamping profile 50 is provided which is fastened to the guide portion 44 of each jaw 38, 40 and is configured to engage the tool plate 14 or the frame 16 preferably along its entire length. The clamping profile 50 connects the two first jaws 38 and the two second jaws 40, respectively (see Figure 3 ).

[0074] The jaws 38, 40 each comprise a solid portion 52 which is fixed between the two sheet metal parts and thereby holds the sheet metal parts in a fixed position relative to each other. The solid portion 52 thus ensures sufficient stability of the jaws 38, 40. The solid portion 52 also serves to fix the clamping profile 50 to the jaws 38, 40.

[0075] The actuator 18 includes a movable piston 54 and a piston rod 56 coupled to the piston 54. The movable piston 54 is contained in a cylinder 58.

[0076] The closing spring 20 is arranged coaxially with the piston rod 56, in particular around the piston rod 56. Thus, the piston rod 56 supports and guides the closing spring 20.

[0077] The closing spring 20 is arranged so as to move the clamping jaw 38 towards its locking position. In other words, the closing spring 20 pushes the first clamping jaw 38 towards the second clamping jaw 40.

[0078] In order to hold the closing spring 20 in a defined position, the closing spring 20 is clamped between the first abutment surface 64 and the second abutment surface 66 (see FIG. Figure 1 and Figure 2 ).

[0079] In the embodiment shown, the first abutment surface 64 is constituted by the actuator 18, in particular the piston rod 56, and the second abutment surface 66 has a fixed position in the mounting device 12. In particular, the second abutment surface is arranged at one guide element 22.

[0080] However, the abutment surfaces 64 , 66 may also be located elsewhere in the machine and the closing spring 20 may be mounted independently of the piston rod 56 .

[0081] In the illustrated embodiment, the actuator 18 is provided with an attachment point 60 having a fixed position relative to the first jaw 38 (see FIG. Figure 1 and Figure 2 ) is coupled to the first jaw 38. Therefore, the distance between the actuator 18 and the first jaw 38 is fixed after the mounting device 12 is assembled. In particular, the actuator 18 is coupled to the guide portion 44 of the first jaw 38.

[0082] The attachment point 60 is arranged directly at the first clamping jaw 38. However, the attachment point 60 can also be arranged at an additional coupling element fixed to the first clamping jaw 38, for example when a larger distance has to be overcome between the clamping jaw 38 and the actuator 18.

[0083] A piston rod 56 is coupled to the first jaw 38, and a cylinder 58 containing a piston 54 is coupled to the second jaw 40. However, the arrangement of the parts may also be reversed.

[0084] like Fig.10 As shown, the actuator 18 is coupled to the jaw 38 via a rotary joint 62 .

[0085] Fig.11 Shown through Figure 1 and Figure 2 Detailed cross-sectional view of the adjustment device 24 is shown in FIG.

[0086] For each second clamping jaw 40, an adjustment device 24 is provided.

[0087] The adjustment device 24 includes a set screw 68 fixed to the second jaw 40, particularly such that the set screw 68 can rotate relative to the second jaw 40, but not move linearly or otherwise displace relative to the second jaw 40. More precisely, the set screw 68 extends through and is fixed to the solid portion 52 of the second jaw 40.

[0088] This is achieved by two bearings 70, 72 which clamp the second jaw 40 between them. Optionally, one of the two bearings 70, 72 is integrally formed with the set screw 68, wherein the other bearing 70, 72 is fastened to the set screw 68.

[0089] The set screw 68 is provided with a knob 74 at one end which can be grasped and rotated by a user.

[0090] The set screw 68 has threads 76 at the other end that engage with corresponding internal threads 78 of a nut 80 that is rotationally and linearly fixed in the mounting device 12 , for example in the crossbar 36 .

[0091] When the set screw 68 is rotated, the set screw 68 is screwed into or out of the thread 76 of the nut 80. Thus, since the nut 80 is fixed, the second jaw 40 moves linearly along the moving direction of the jaws 38, 40.

[0092] Fig.12 A section through an adjustment device 24 according to an alternative embodiment is shown.

[0093] The regulating device is based on Fig.11 The same mechanism as the adjustment device 24 shown in FIG.

[0094] However, instead of the nut 80, according to Fig.12 The adjustment device 24 comprises a screw 82 with an internal thread, into which the stop screw 68 is screwed.

[0095] When the set screw 68 is rotated, the set screw 68 is screwed into the bolt 82 or screwed out of the bolt 82 .

[0096] The bolt 82 is supported by the crossbar 36 , in particular, it abuts the crossbar 36 or is coupled to another element of the crossbar 36 , but is not fixedly secured to the crossbar 36 .

[0097] In the following, the processing and functions of the mounting device 12 are described with reference to the previously described figures.

[0098] If it is necessary to insert or replace the tool plate 14, the actuator 18 is actuated. In particular, the actuator 18 is only used to open the mounting device 12, but not to close the mounting device 12.

[0099] The actuation of each actuator 18 is carried out by applying pressurized air to the piston 54, in particular by filling the cylinder 58 with pressurized air. As a result, the piston 54 moves, so that the actuator 18 is extended and the first jaw 38 connected to the actuator 18 is moved from its locked position to its unlocked position. This movement is performed by Figure 1 and Figure 2 Visualization.

[0100] In particular, the first jaw 38 moves against the force of the closing spring 20 .

[0101] When the first jaw 38 moves, the closing spring 20 is compressed because the abutment surfaces 64, 66 move toward each other. Thus, the closing spring 20 stores elastic energy.

[0102] The same movement occurs simultaneously in the parallel second bridge 28 and its actuator 18 .

[0103] In this case, the tool plate 14 or frame 16 may be inserted into the mounting device 12 when the actuator 18 is actuated and the closing spring 20 is compressed.

[0104] During the insertion of the tool plate 14 or the frame 16 , the clamping contour 50 facilitates easy replacement of the tool plate 14 or the frame 16 , since the tool plate 14 or the frame 16 is supported by the clamping contour 50 , even if the mounting device 12 is still in the unlocked state.

[0105] During insertion, the centering device 26 engages with the tool plate 14 or the frame 16 so as to center the tool plate 14 in the mounting device 12 in a direction perpendicular to the direction of movement of the paper or paperboard.

[0106] After the tool plate 14 has been inserted, the actuator 18 can be deactivated, in particular by stopping the supply of pressurized air.

[0107] When the gas pressure in the gas cylinder 58 is reduced again, the first clamping jaw 38 moves back to its locking position due to the elastic force of the closing spring 20 .

[0108] If the position of the tool plate 14 needs to be fine-tuned, the second clamping jaw 40 can be moved in the movement direction of the clamping jaws 38 , 40 by means of the adjusting device 24 .

[0109] In particular, the user can rotate the knob 74 to move the corresponding second jaw 40. In particular, when the knob 74 and the set screw 68 are rotated, the second jaw 40 moves linearly.
