Description

The invention relates to a breaking-out device according to the preamble of claim 1 or claim 7 and a use-separating device according to the preamble of claim 2 or claim 8, in particular for a sheet punching and embossing machine, as well as a method of setting up such a device according to claims 10 and 11 ,

As punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds. Also the practices practiced in print finishing, such as punching with punch, corner punching and register punching are counted to this area. The punching takes place against a punching pad or against stamp, in some cases it is also shearing operations. Packaging materials made of paper, cardboard, cardboard or corrugated board are mainly punched in sheet format. When punching but also creasing lines or blind embossing can be introduced into the benefit. This complex process makes it indispensable to punch the sheets individually. Since the end products are sophisticated packaging in terms of technical and graphic design (such as packaging for cosmetics, cigarettes, pharmacy, food, etc.), special requirements are not only placed on the packaging materials themselves, but are also punching tools for optimum results required with the smallest tolerances and extremely precise and reliable punching machines. Flatbed punching best meets these demands. The printed sheets stacked on a pallet are fed to the punching machine. In the machine, the sheets to be punched are precisely aligned in an alignment device, taken over by a gripper carriage and positioned exactly in the punching device between a fixed undercounter and a vertical over a knee lever or eccentric upper table.

In known sheet punching and embossing machines, which are used for punching, breaking, stamping and depositing sheets of paper, cardboard and the like, it is known to move the sheets by means of gripper carriage through the individual stations of the machine. Grippers are attached to the gripper carriages which hold the arches at a front end take the gripper carriage to be moved even on endless chains through the machine. This type of movement of the sheets through the machine enables continuous operation in the individual successively arranged stations of the machine.

Such a flat bed punch is for example from the DE 30 44 083 A1 known. The two tables are equipped with cutting and scoring tools or corresponding counter tools with which punched out of the cyclically guided between the table surface sheets the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designated Nutzentrenneinrichtung.

A stripping tool usually consists of an upper tool and a lower tool, which are each equipped with Ausbrechstiften. In this case, take the pins of the upper tool and the congruent thereto arranged pins of the lower tool the blank waste between them and push through a breakout board on which the waste-free zones are not perforated and the waste zones are recessed by corresponding recesses. This breaks the breakpoints between blank trimmings and benefits. The number of stripping pins required varies from less than 10 to more than 500, depending on the die pattern of the die assembly. With a large number of stripping pins, the time required to set up the tool is very high, which affects the productivity of the sheet punching and embossing machine.

Also, the blanking tool must be created individually according to the die and the benefit distribution. In contrast to the stripping tool here usually no Ausbrechstifte, but ejection bodies are used. These ejector push out of the cardboard sheet the individual benefits through a grid-like abutment and solve the cardboard bridges between sheet and benefits, ie the so-called breakpoints.

The DE 600 12 833 T2 describes a universal breakout tool having two parallel plates pierced with a plurality of holes distributed uniformly throughout its surface. In the holes specially shaped Ausbrechstifte be plugged, which are held by spring force in the plates. This design allows the universal breakout tool to be modified and adjusted to the punching job with a simple operation without the additional use of tools. However, with a high number of stripping pins in the tool, a great deal of time is required for setting up, which affects the productivity of the sheet punching and embossing machine.

The DE 40 24 137 A1 shows a stripping tool, in which the Ausbrechstifte can be attached by means of a permanent magnet to connected to the frame of the stripping tool carriers. Next describes the DE 40 24 137 A1 a device for equipping the lower tool of a stripping tool, wherein the already created upper tool is used as a template for this purpose. Both measures serve to reduce set-up times and increase productivity. However, with a large number of breakout pins, due to the manual positioning of the breakout pins in the upper tool, a high amount of time is still required.

This is based on the same principle in the DE 198 60 899 A1 blanking tool described: ejector bodies are magnetically or electromagnetically connectable to a plate-shaped support means. The ejector body can be quickly assembled into different contours and adapted to the punching pattern. Due to the dimensions of the ejection body, however, no arbitrary exact adaptation of the Nutzentrennwerkzeugs to the die and the benefit distribution is possible.

A disadvantage of all known from the prior art solutions is despite improvement attempts still high expenditure of time when setting up the tools. The amount of time is further increased if the lower tool is equipped with lower pins, which must be aligned relative to the upper pins. The high time required to set up the tools greatly affects the productivity of a sheet punching and embossing machine. Next disadvantageous to the tools according to The state of the art is that the storage of order-specific tools is complicated and costly.

The object of the present invention is therefore to avoid the disadvantages of the tools known from the prior art and to increase the machine productivity by using tools with short set-up times. This object is achieved by devices with universal tools according to the characterizing part of claim 1 and 2 and claim 7 and 8 and by the method according to claim 10 and 11, i. in particular through automation of the tool production.

The stripping device according to the invention with stripping board and universal stripping tool is used to break out waste from plate-like workpieces made of paper, cardboard, plastic, films, thin sheet and the like. The Nutzentrenngitter invention with Nutzentrenngitter and universal Nutzentrennwerkzeug serves the Nutzentrennen and storing products from plate-like workpieces. Both devices are used in particular in sheet punching and embossing machines. The universal tools of the devices according to the invention may have a tool frame, which may be included, for example, in the breaking station and the pay dividing station of a sheet punching and embossing machine, or they may be frameless and be included directly in the breaking station and the pay dividing station of a sheet punching and embossing machine , In the tool frame of the universal tools at least one mounting plate and a worktop are stored. These each have a plurality of holes distributed over their entire surface and a plurality of pins which are plugged into the holes of the plates. The plates of a universal tool are mounted parallel to each other in the horizontal in the tool frame, wherein a pin is assigned to a hole of at least one mounting plate and a hole of the at least one worktop. For example, the center line of each hole of the mounting plate can be aligned with the center line of a hole of the work surface. The plates are separately height adjustable and each have a locking mechanism for clamping the pins in the holes. To height-adjust the plates without play, the plates are ideally guided in its four corners in a round guide. The universal tools are each upper tools.

Part of the invention is also an alternative embodiment of a universal tool, which makes do with only one plate and a simple height adjustment of the universal tool. The device according to the invention is used in particular for use in a sheet punching and embossing machine. The breaker is used to break out waste from plate-like workpieces made of paper, cardboard and the like and has a breakout board. The Nutzentrennvorrichtung serves the Nutzentrennen and storing products made of paper, cardboard and the like and has a Nutzentrenngitter. The devices also each have one Universal tool with at least one worktop, which is pierced with a plurality of holes distributed on its surface. The worktop is mounted in the horizontal parallel to the sheet transport plane. A variety of pins can be plugged through the holes of the worktop. The breaking-out board of the breaking-out device or the blanking grid of the blanking device is fastened parallel to the working plate. The universal tool is height adjustable and has a locking mechanism for clamping the pins. By height adjustment of the universal tool and by activating and deactivating the locking mechanism, the contour of the stripping board or the Nutzentrenngitters can be represented by the pins.

In an advantageous embodiment of the device, the locking mechanism is formed by a magnetorheological locking mechanism. This has magnetorheological active elements, such as a magnetorheological fluid, which surrounds parts of the pins, and means for generating a magnetic field. The liquid is in a housing.

Part of the invention is also a method for setting up a universal tool, in particular in a sheet punching and embossing machine. A universal tool for breaking up waste from plate-like workpieces made of paper, cardboard and the like must be adapted to the punching of a respective punching order to safely break the waste out of the workpieces can. In a first step, a populated with a plurality of pins mounting plate is lowered from its upper position in a tool frame to a second step, the lower ends of the pins in the holes of a second, to the assembly plate parallel plate, a worktop, retract. So far, the pins are held to their heads by the locking mechanism of the mounting plate. In a third step, the locking mechanism of the mounting plate is brought out of action and the heads of the pins are thereby released. This allows the pins to fall into the holes of the worktop in a fourth step so that the pins rest with their heads on the top of the worktop. In a fifth step, the worktop is lowered so that the lower ends of the pins abut the breakout board located parallel to and underneath the worktop or dip into recesses in the breakout board. The pins form the contour of the Stripping boards after. In a sixth step, the mounting plate is lowered until the heads of a part of the pins, namely all those pins that come with their lower end to the breaking board, retract into the holes of the mounting plate. In a seventh step, the locking mechanism of the mounting plate is activated, the heads of one part of the pins are clamped and the mounting plate is lifted off. In a final step, the working plate locking mechanism is activated to clamp the remaining pins which are not clamped by the locking mechanism of the mounting plate. Thus, the universal tool is set up and equipped with pins countertop can be used to edit the plate-like workpieces.

The inventive method for setting up a universal tool for Nutzentrennen of plate-like workpieces made of paper, cardboard and the like, in particular in a sheet punching and embossing machine, has the same process steps as the method for setting up a universal stripping. In the fifth step, analogously to the above description, the worktop is lowered, so that the lower ends of the pins abut the load-dividing grid located parallel to and underneath the worktop or submerge in free spaces of the blanking grid. This shows the contour of the blanking grid.

In FIG. 1 the basic structure of a sheet punching and embossing machine 100 for punching, breaking and depositing sheets of paper, cardboard and the like is shown. The punching and embossing machine 100 has a feeder 1, a punching station 2, a breaking station 3 and a boom 4, which are supported and enclosed by a common machine housing 5.

The sheets 6 are separated by a feeder 1 from a stack, fed to the sheet transport system 7 and gripped by gripper carriage 8 grippers at its front edge and intermittently in the sheet transport direction B in the sheet transport plane E through the various stations 2, 3 and 4 of the punching and Embossing machine 100 pulled through.

The punching station 2 consists of a lower table 9 and an upper table 10. The lower table 9 is fixedly mounted in the machine frame and provided with a counter plate to the punching knife. The upper table 10 is supported vertically movable back and forth.

The gripper carriage 8 transports the sheet 6 from the punching and embossing station 2 in the subsequent Ausbrechstation 3, which is equipped with breakout tools 20. In the stripping station 3, the unwanted pieces of waste are pushed out of the sheet 6 downwards with the aid of the stripping tools 20, whereby the waste pieces 11 fall into a container-like carriage 12 inserted below the station.

From the breaking station 3, the sheet 6 passes into the boom 4, where the sheet 6 is either stored and at the same time a separation of the individual benefits by means of a Nutzentrennwerkzeuges 20 takes place. The boom 4 may also include a pallet 13 on which the individual sheets 6 are stacked in the form of a stack 14, so that after reaching a certain stack height, the pallets 14 can be moved away with the stacked sheets 6 from the field of punching and embossing machine 100 ,

8, so that multiple sheets 6 can be processed simultaneously in the various stations 2, 3 and 4. shows a stripping device according to the invention with universal stripping tool 20 and stripping 24 in its working position. The breakout board 24 is located parallel to and below the sheet transport plane E. The universal tool 20 consists of a mounting plate 21, a countertop 22, a plurality of pins 25, a locking mechanism 26 (not shown) and a device (not shown) for the separate height adjustment of Platen 21 and the worktop 22. These elements are all mounted in a tool frame (not shown). Both mounting plate 21 and work plate 22 have a plurality of holes 23, wherein the diameter of the holes 23 in the mounting plate 21 corresponds to the diameter in the head portion of a pin 25 and wherein the diameter of the holes 23 in the work plate 22 the diameter in the foot region of a pin 25th equivalent. Placement plate 21 and work plate 22 and stripping board or Nutzentrenngitter 24 parallel to each other and arranged parallel to the sheet transport plane E. The turn center line of a hole 23 in the mounting plate 21 is aligned with the center line of a hole 23 of the work surface 22nd

In Fig. 2 the use of a universal tool 20 for breaking up pieces of waste 11 from a sheet 6 is shown. For processing a sheet 6, the worktop 22 moves in the direction of movement b on the sheet 6. The clamped in the countertop 22 pins 25 meet with their feet on the sheet 6, break pieces of waste 11 from the sheet 6 and push them through exceptions in the breakout board 24 therethrough.

In the FIGS. 3a to 3e the setup process of a universal tool is shown. As in Fig. 3a shown, all pins 25 are clamped by the locking mechanism 26 of the mounting plate 21 at the beginning. The locking mechanism 27 of the worktop 22 is out of action. The locking mechanisms 26 and 27 are, as shown schematically here, electromagnets. Below the countertop 22 is a breakout board 24 with one exception. Based on this initial situation, the stripping tool is set up. In Fig. 3b the locking mechanism 26 of the mounting plate 21 has been rendered inoperative. As a result, the pins 25 were released and could dive deeper into the holes 23 of the countertop 22. With their heads, the pins 25 are on the surface of the Arbeitsplatt 22. The worktop 22 lowers in the direction of movement b down on the breakout board 24 to. Fig. 3c shows a snapshot at a later date. The worktop 22 has been further lowered and is in its lowest point and some pins 25 abut with their feet on the breakout board 24. Other pins 25 continue to lie with their head on the countertop 22. The feet of these pins 25 are immersed in exceptions of Ausbrechbretts 24. The mounting plate 21 is lowered in the direction of movement a. Fig. 3d is a representation at a later date. The mounting plate 21 has been further lowered and is in its lowest point and resting with their feet on the breakout board 24 pins 25 dive with their heads in the holes 23 of the mounting plate 21 a. The locking mechanism 26 of the mounting plate 21 is activated to clamp the pins 25. The mounting frame 21 is, as in Fig. 3e shown, lifted in the direction of movement a. With the mounting plate 21 those pins 25 are lifted off, which are not required for breaking up waste pieces 11 (not shown) from the sheet 6 (not shown). The locking mechanism 27 of the work surface 22 is activated to clamp the pins 25, which are required for breaking the waste pieces 11 (not shown) from the sheet 6 (not shown). The universal tool 20 thus arranged can now, as in Fig. 2 shown used.

Fig. 4 shows a universal stripping tool 20 and a breakout board 24, which are arranged parallel to each other. The universal tool 20 has a work surface 22 which is penetrated by holes 23. In the holes pins 25 are guided. Between holes 23 and pins 25 are seals, z. B. O-ring seals, which are not shown. Above the work plate 22 is a magnetorheological locking mechanism 30. The locking mechanism 30 has a housing 33 in which magnetorheological fluid 31 is located. The heads of the pins 25 are surrounded by the liquid 31. At the edge of the housing 33 is a device for generating a magnetic field 32. When the universal tool 20 is in the lowered state and the pins 25 depict the contour of the breaking-out board 24, the field generating device 32 generates a magnetic field which is related to the magnetorheological Liquid 31 acts. The liquid 31 solidifies, enclosing the heads of the pins 25, thereby fixing the pins 25.

Fig. 5 shows a Universalausbrechwerkzeug 20 and a breakout board 24. In contrast to Fig. 4 the locking mechanism is designed as an electrorheological locking mechanism 40. This has - analogous to the magnetorheological solution - a housing 43 in which an electrorheological fluid 41 is located, which surrounds the pins 25. By means for generating an electric field 42, an electric field can be produced which acts on the electrorheological fluid so that it solidifies and fixes the pins 25.
