Description

Die Erfindung betrifft eine Ausbrechvorrichtung gemäß dem Oberbegriff von Anspruch 1 oder Anspruch 7 und eine Nutzentrennvorrichtung gemäß dem Oberbegriff von Anspruch 2 oder Anspruch 8, insbesondere für eine Bogenstanz- und -prägemaschine, als auch ein Verfahren zum Einrichten einer solchen Vorrichtung gemäß Anspruch 10 und 11.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 ,

Als Stanzen wird das Schneiden mit in sich geschlossenen geometrischen Zuschnittsformen bezeichnet, die kreisförmig, oval oder mehreckig sowie Phantasieformen aller Art sein können. Auch die in der Druckweiterverarbeitung geübten Praktiken, wie Stanzen mit Locheisen, Eckenabstoßen und Registerstanzen werden zu diesem Bereich gezählt. Die Stanzung erfolgt gegen eine Stanzunterlage oder gegen Stempel, teilweise sind es auch Schervorgänge. Verpackungsmaterialien aus Papier, Karton, Pappe oder Wellpappe werden hauptsächlich im Bogenformat gestanzt. Beim Stanzvorgang können zusätzlich aber auch Rilllinien oder Blindprägungen in den Nutzen eingebracht werden. Dieser komplexe Prozess macht es unabdingbar, die Bogen einzeln zu stanzen. Da es sich bei den Endprodukten um anspruchsvolle Verpackungen hinsichtlich technischer und graphischer Ausführung handelt (etwa Verpackungen für Kosmetik, Zigaretten, Pharmazie, Lebensmittel, etc.), werden besondere Anforderungen nicht nur an die Verpackungsmaterialien selbst gestellt, sondern es sind für optimale Resultate auch Stanzwerkzeuge mit geringsten Toleranzen und äußerst präzise und zuverlässig arbeitende Stanzmaschinen erforderlich. Diesen Ansprüchen wird das Flachbettstanzen am besten gerecht. Dabei werden die gedruckten und auf einer Palette gestapelten Bogen der Stanzmaschine zugeführt. In der Maschine werden in einer Ausrichteinrichtung die zu stanzenden Bogen passgenau ausgerichtet, von einem Greiferwagen übernommen und exakt in der Stanzeinrichtung zwischen einem fest gelagerten Untertisch und einem über einen Kniehebel oder Exzentergetriebe vertikal bewegbaren Obertisch positioniert.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 bekannten Bogenstanz- und Prägemaschinen, die zum Stanzen, Ausbrechen, Prägen und Ablegen von Bögen aus Papier, Pappe und der gleichen eingesetzt werden, ist es bekannt die Bögen mittels Greiferwagen durch die einzelnen Stationen der Maschine zu bewegen. An den Greiferwagen sind Greifer befestigt, die die Bögen an einem vorderen Ende ergreifen, wobei die Greiferwagen selbst an endlosen Ketten durch die Maschine bewegt werden. Durch diese Art der Bewegung der Bögen durch die Maschine wird ein kontinuierliches Arbeiten in den einzelnen hintereinander angeordneten Stationen der Maschine ermöglicht.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.

Eine derartige Flachbettstanze ist beispielsweise aus der DE 30 44 083 A1 bekannt. Die beiden Tische sind mit Schneid- und Rillwerkzeugen bzw. entsprechenden Gegenwerkzeugen bestückt, mit denen aus dem taktweise zwischen die Tischfläche geführten Bögen die Nutzen ausgestanzt und gleichzeitig die zum sauberen Falten notwendigen Rillen eingedrückt werden. In der nachfolgenden Ausbrecheinrichtung wird der Abfall über Ausbrechwerkzeuge maschinell entfernt. Je nach Ausstattung der Maschine können schließlich die gestanzten Nutzen in einer hierfür vorgesehenen Nutzentrenneinrichtung separiert werden.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.

Ein Ausbrechwerkzeug besteht dabei in der Regel aus einem Oberwerkzeug und einem Unterwerkzeug, die jeweils mit Ausbrechstiften bestückt sind. Dabei ergreifen die Stifte des Oberwerkzeuges und die deckungsgleich dazu angeordneten Stifte des Unterwerkzeuges die Zuschnittabfälle zwischen sich und drücken sie durch eine Ausbrechbrett, auf der die abfallfreien Zonen ungelocht und die Abfallzonen durch entsprechende Ausnehmungen ausgespart sind. Dadurch reißen die Haltepunkte zwischen Zuschnittabfällen und Nutzen ab. Die Anzahl der notwendigen Ausbrechstifte variiert dabei in Abhängigkeit vom Stanzmuster der Nutzenanordnung zwischen unter 10 und mehr als 500. Bei einer großen Anzahl von Ausbrechstiften ist der Zeitaufwand zum Einrichten des Werkzeugs sehr hoch, was die Produktivität der Bogenstanz- und - prägemaschine beeinträchtigt.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.

Auch das Nutzentrennwerkzeug muss individuell entsprechend der Stanzform und der Nutzenaufteilung erstellt werden. Im Gegensatz zum Ausbrechwerkzeug kommen hier in der Regel keine Ausbrechstifte, sondern Ausstoßkörper zum Einsatz. Diese Ausstoßkörper drücken aus dem Kartonbogen die einzelnen Nutzen durch ein gitterartiges Widerlager und lösen dabei die Kartonbrücken zwischen Bogen und Nutzen, d. h. die sogenannten Haltepunkte.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.

Die EP-A-1 101 579 beschreibt ein Universalausbrechwerkzeug, welches zwei parallele Platten besitzt, die mit einer Vielzahl von gleichmäßig auf ihrer gesamten Fläche verteilten Löchern durchbohrt sind. In die Löcher können speziell ausgeformte Ausbrechstifte gesteckt werden, welche durch Federkraft in den Platten gehalten werden. Dieser Aufbau ermöglicht, dass das Universalausbrechwerkzeug mit einfachen Handgriffen ohne den zusätzlichen Einsatz von Werkzeugen verändert und an den Stanzauftrag angepasst werden kann. Bei einer hohen Anzahl von Ausbrechstiften im Werkzeug ist jedoch trotzdem ein großer Zeitaufwand fürs Einrichten notwendig, was die Produktivität der Bogenstanz- und -prägemaschine beeinträchtigt.The EP-A-1 101 579 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.

Die DE 40 24 137 A1 zeigt ein Ausbrechwerkzeug, bei dem die Ausbrechstifte mit Hilfe eines Dauermagneten an mit dem Rahmen des Ausbrechwerkzeugs verbundenen Trägern angebracht werden können. Weiter beschreibt die DE 40 24 137 A1 eine Vorrichtung zur Bestückung des Unterwerkzeugs eines Ausbrechwerkzeugs, wobei dazu das bereits erstellte Oberwerkzeug als Vorlage herangezogen wird. Beide Maßnahmen dienen dazu, die Rüstzeiten zu reduzieren und die Produktivität zu erhöhen. Bei einer großen Anzahl von Ausbrechstiften ist aufgrund des manuellen Positionierens der Ausbrechstifte im Oberwerkzeug jedoch weiterhin ein hoher Zeitaufwand gegeben.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.

Auf dem gleichen Prinzip basiert das in der DE 198 60 899 A1 beschriebene Nutzentrennwerkzeug: Ausstoßkörper sind magnetisch oder elektromagnetisch mit einer plattenförmigen Trageinrichtung verbindbar. Die Ausstoßkörper können so schnell zu verschiedenen Konturen zusammengefügt und an das Stanzmuster angepasst werden. Aufgrund der Abmaße der Ausstoßkörper ist jedoch keine beliebig genaue Anpassung des Nutzentrennwerkzeugs an die Stanzform und die Nutzenaufteilung möglich.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.

Nachteilig an allen aus dem Stand der Technik bekannten Lösungen ist der trotz Verbesserungsversuchen immer noch hohe Zeitaufwand beim Einrichten der Werkzeuge. Der Zeitaufwand wird noch weiter erhöht, wenn das Unterwerkzeug mit Unterstiften, welche relativ zu den Oberstiften ausgerichtet werden müssen, bestückt ist. Der hohe Zeitaufwand beim Einrichten der Werkzeuge beeinträchtigt die Produktivität einer Bogenstanz- und -prägemaschine immens. Weiter nachteilig an den Werkzeugen gemäß dem Stand der Technik ist, dass die Lagerhaltung der auftragsspezifischen Werkzeuge aufwendig und kostenintensiv ist.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.

Aufgabe der vorliegenden Erfindung ist es deshalb, die Nachteile der aus dem Stand der Technik bekannten Werkzeuge zu vermeiden und die Maschinenproduktivität durch Einsatz von Werkzeugen mit kurzen Rüstzeiten zu erhöhen. Gelöst wird diese Aufgabe durch Vorrichtungen mit Universalwerkzeugen gemäß dem kennzeichnenden Teil von Anspruch 1 und 2 und Anspruch 7 und 8 sowie durch Verfahren gemäß Anspruch 10 und 11, d.h. insbesondere durch eine Automatisierung der Werkzeugerstellung.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 methods according to claim 10 and 11, i. in particular through automation of the tool production.

Teil der Erfindung ist auch eine alternative Ausführungsform eines Universalwerkzeuges, welche mit nur einer Platte und einer einfachen Höhenverstellung des Universalwerkzeuges auskommt. Die erfindungsgemäße Vorrichtung dient insbesondere dem Einsatz in einer Bogenstanz- und -prägemaschine. Die Ausbrechvorrichtung dient dem Ausbrechen von Abfällen aus plattenartigen Werkstücken aus Papier, Pappe und dergleichen und besitzt ein Ausbrechbrett. Die Nutzentrennvorrichtung dient dem Nutzentrennen und Ablegen von Produkten aus Papier, Pappe und dergleichen und besitzt ein Nutzentrenngitter. Die Vorrichtungen besitzen weiterhin jeweils ein Universalwerkzeug mit mindestens einer Arbeitsplatte, welche mit einer Vielzahl von auf ihrer Fläche verteilten Löchern durchbohrt ist. Die Arbeitsplatte ist in der Horizontalen parallel zur Bogentransportebene angebracht. Eine Vielzahl von Stiften ist durch die Löcher der Arbeitsplatte steckbar. Das Ausbrechbrett der Ausbrechvorrichtung bzw. das Nutzentrenngitter der Nutzentrennvorrichtung ist parallel zur Arbeitsplatte befestigt. Das Universalwerkzeug ist höhenverstellbar und besitzt einen Arretierungsmechanismus zum Klemmen der Stifte. Durch Höhenverstellen des Universalwerkzeugs und durch Aktivieren und Deaktivieren des Arretierungsmechanismus kann die Kontur des Ausbrechbretts bzw. des Nutzentrenngitters durch die Stifte abgebildet werden.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 einer vorteilhaften Ausführungsform der Vorrichtung wird der Arretierungsmechanismus durch einen magnetorheologischen Arretierungsmechanismus gebildet. Dieser besitzt magnetorheologische Wirkelemente, wie eine magnetorheologische Flüssigkeit, welche Teile der Stifte umgibt, und eine Einrichtung zur Erzeugung eines magnetischen Feldes. Die Flüssigkeit befindet sich in einem Gehäuse. Wird ein magnetisches Feld erzeugt, so werden die Stifte durch die magnetorheologische Flüssigkeit fixiert.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.

Parts of the pins of the universal tool are surrounded by the electrorheological fluid, which is located in a housing. When an electric field is applied, the pins of the universal tool are fixed by the electrorheological fluid.

In einer bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung sind die Stifte überwiegend aus einem leichten Material, wie beispielsweise Aluminium oder Kunststoff, gefertigt. Dadurch wird das Gewicht reduziert, welches auf den Platten lastet und welches zu einer Verformung der Platten führen kann. In einer besonders bevorzugten Ausführungsform der Universalwerkzeuge sind die Stifte so ausgeformt, dass sie im Bereich ihres Kopfes einen größeren Durchmesser aufweisen als im Bereich ihres unteren Endes. Weiter vorteilhaft ist es, wenn die Löcher der Bestückungsplatte denselben Durchmesser haben wie die Köpfe der Stifte und die Löcher der Arbeitsplatte denselben Durchmesser haben wie die Füße der Stifte.In a preferred embodiment of the device according to the invention, the pins are predominantly made of a light material, such as aluminum or plastic. As a result, the weight is reduced, which rests on the plates and which can lead to deformation of the plates. In a particularly preferred embodiment of the universal tools, the pins are formed so that they have a larger diameter in the region of their head than in the region of their lower End. It is also advantageous if the holes of the mounting plate have the same diameter as the heads of the pins and the holes of the worktop have the same diameter as the feet of the pins.

Teil der Erfindung ist auch ein Verfahren zum Einrichten eines Universalwerkzeuges, insbesondere in einer Bogenstanz- und -prägemaschine. Ein Universalwerkzeug zum Ausbrechen von Abfällen aus plattenartigen Werkstücken aus Papier, Pappe und dergleichen muss auf die Stanzform eines jeweiligen Stanzauftrags angepasst sein, um die Abfälle sicher aus den Werkstücken ausbrechen zu können. Dazu wird ein Universalwerkzeug gemäß dem erfindungsgemäßen Verfahren in mehreren Schritten eingerichtet: In einem ersten Schritt wird eine mit einer Vielzahl von Stiften bestückte Bestückungsplatte von ihrer oberen Position in einem Werkzeugrahmen abgesenkt bis in einem zweiten Schritt die unteren Enden der Stifte in die Löcher einer zweiten, zur Bestückungsplatte parallelen Platte, einer Arbeitsplatte, einfahren. Bis hierher werden die Stifte an ihren Köpfen vom Arretierungsmechanismus der Bestückungsplatte gehalten. In einem dritten Schritt wird der Arretierungsmechanismus der Bestückungsplatte außer Wirkung gebracht und die Köpfe der Stifte werden dadurch freigegeben. Dies ermöglicht, dass die Stifte in einem vierten Schritt in die Löcher der Arbeitsplatte fallen, so dass die Stifte mit ihren Köpfen auf der Plattenoberseite der Arbeitsplatte aufliegen. In einem fünften Schritt wird die Arbeitsplatte abgesenkt, so dass die unteren Enden der Stifte an das sich parallel und unterhalb der Arbeitsplatte befindliche Ausbrechbrett stoßen oder in Aussparungen im Ausbrechbrett eintauchen. Die Stifte bilden so die Kontur des Ausbrechbretts nach. In einem sechsten Schritt wird die Bestückungsplatte abgesenkt bis die Köpfe eines Teils der Stifte, nämlich all diejenigen Stifte, die mit ihrem unteren Ende an das Ausbrechbrett stoßen, in die Löcher der Bestückungsplatte einfahren. In einem siebten Schritt wird der Arretierungsmechanismus der Bestückungsplatte aktiviert, die Köpfe des einen Teils der Stifte geklemmt und die Bestückungsplatte abgehoben. In einem letzten Schritt wird der Arretierungsmechanismus der Arbeitsplatte aktiviert, um die verbleibenden Stifte zu klemmen, welche nicht vom Arretierungsmechanismus der Bestückungsplatte geklemmt sind. Damit ist das Universalwerkzeug eingerichtet und die mit Stiften bestückte Arbeitsplatte kann zur Bearbeitung der plattenartigen Werkstücke eingesetzt werden.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.

Das erfindungsgemäße Verfahren zum Einrichten eines Universalwerkzeugs zum Nutzentrennen von plattenartigen Werkstücken aus Papier, Pappe und dergleichen, insbesondere in einer Bogenstanz- und -prägemaschine, besitzt die selben Verfahrensschritte, wie das Verfahren zum Einrichten eines Universal-Ausbrechwerkzeuges. Im fünften Schritt wird analog zur obigen Beschreibung die Arbeitsplatte abgesenkt, so dass die unteren Enden der Stifte an das sich parallel und unterhalb der Arbeitsplatte befindliche Nutzentrenngitter stoßen oder in freie Räume des Nutzentrenngitters eintauchen. So wird die Kontur des Nutzentrenngitters abgebildet.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-separating grid located parallel to and underneath the worktop or submerge into free spaces of the useful divider. This shows the contour of the blanking grid.

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 worktop 22 and stripping board or Nutzentrenngitter 24 are arranged parallel to each other and parallel to the sheet transport plane E. The 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 22.

In Fig. 2 ist der Einsatz eines Universalwerkzeugs 20 zum Ausbrechen von Abfallstücken 11 aus einem Bogen 6 dargestellt. Zur Bearbeitung eines Bogens 6 bewegt sich die Arbeitsplatte 22 in Bewegungsrichtung b auf den Bogen 6 zu. Die in der Arbeitsplatte 22 geklemmten Stifte 25 treffen mit ihren Füßen auf den Bogen 6, brechen Abfallstücke 11 aus dem Bogen 6 aus und drücken diese durch Ausnahmen im Ausbrechbrett 24 hindurch.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 den Figuren 3a bis 3e ist der Einrichtevorgang eines Universalwerkzeugs dargestellt. Wie in Fig. 3a dargestellt, sind zu Beginn alle Stifte 25 vom Arretierungsmechanismus 26 der Bestückungsplatte 21 geklemmt. Der Arretierungsmechanismus 27 der Arbeitsplatte 22 ist außer Funktion. Bei den Arretierungsmechanismen 26 und 27 handelt es sich, wie hier schematisch dargestellt, um Elektromagnete. Unterhalb der Arbeitsplatte 22 befindet sich ein Ausbrechbrett 24 mit einer Ausnahme. Ausgehend von dieser Ausgangssituation wird das Ausbrechwerkzeug eingerichtet. In Fig. 3b wurde der Arretierungsmechanismus 26 der Bestückungsplatte 21 außer Funktion gebracht. Dadurch wurden die Stifte 25 freigegeben und konnten tiefer in die Löcher 23 der Arbeitsplatte 22 eintauchen. Mit ihren Köpfen liegen die Stifte 25 auf der Oberfläche der Arbeitsplatte 22 auf. Die Arbeitsplatte 22 senkt sich in der Bewegungsrichtung b abwärts auf das Ausbrechbrett 24 zu. Fig. 3c zeigt eine Momentaufnahme zu einem etwas späteren Zeitpunkt. Die Arbeitsplatte 22 wurde weiter abgesenkt und befindet sich in ihrem tiefsten Punkt und manche Stifte 25 stoßen mit ihren Füßen an das Ausbrechbrett 24 an. Andere Stifte 25 liegen weiterhin mit ihrem Kopf auf der Arbeitsplatte 22 auf. Die Füße dieser Stifte 25 sind in Ausnahmen des Ausbrechbretts 24 eingetaucht. Die Bestückungsplatte 21 wird in Bewegungsrichtung a abgesenkt. Fig. 3d ist eine Darstellung zu einem etwas späteren Zeitpunkt. Die Bestückungsplatte 21 wurde weiter abgesenkt und befindet sich in ihrem tiefsten Punkt und die mit ihren Füßen auf dem Ausbrechbrett 24 aufliegenden Stifte 25 tauchen mit ihren Köpfen in die Löcher 23 der Bestückungsplatte 21 ein. Der Arretierungsmechanismus 26 der Bestückungsplatte 21 wird aktiviert, um die Stifte 25 zu klemmen. Der Bestückungsrahmen 21 wird, wie in Fig. 3e dargestellt, in Bewegungsrichtung a abgehoben. Mit der Bestückungsplatte 21 werden diejenigen Stifte 25 mit abgehoben, welche zum Ausbrechen von Abfallstücken 11 (nicht dargestellt) aus dem Bogen 6 (nicht dargestellt) nicht benötigt werden. Der Arretierungsmechanismus 27 der Arbeitsplatte 22 wird aktiviert, um die Stifte 25 zu klemmen, welche zum Ausbrechen der Abfallstücke 11 (nicht dargestellt) aus dem Bogen 6 (nicht dargestellt) benötigt werden. Das so eingerichtete Universalwerkzeug 20 kann nun, wie in Fig. 2 dargestellt, eingesetzt werden.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 countertop 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 zeigt ein Universal-Ausbrechwerkzeug 20 und ein Ausbrechbrett 24, welche parallel zueinander angeordnet sind. Das Universalwerkzeug 20 besitzt eine Arbeitsplatte 22, welche von Löchern 23 durchsetzt ist. In den Löchern werden Stifte 25 geführt. Zwischen Löchern 23 und Stiften 25 befinden sich Dichtungen, z. B. O-Ringdichtungen, welche nicht dargestellt sind. Oberhalb der Arbeitsplatte 22 befindet sich ein magnetorheologischer Arretierungsmechanismus 30. Der Arretierungsmechanismus 30 besitzt ein Gehäuse 33, in welchem sich magnetorheologische Flüssigkeit 31 befindet. Die Köpfe der Stifte 25 sind von der Flüssigkeit 31 umgeben. Am Rand des Gehäuses 33 befindet sich eine Einrichtung zur Erzeugung eines Magnetfeldes 32. Wenn sich das Universalwerkzeug 20 in abgesenktem Zustand befindet und die Stifte 25 die Kontur des Ausbrechbretts 24 abbilden, wird durch die Einrichtung zur Felderzeugung 32 ein Magnetfeld erzeugt, welches auf die magnetorheologische Flüssigkeit 31 wirkt. Die Flüssigkeit 31 verfestigt sich, umschließt die Köpfe der Stifte 25 und fixiert damit die Stifte 25. 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 magnetic 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 zeigt ein Universalausbrechwerkzeug 20 und ein Ausbrechbrett 24. Im Gegensatz zu Fig. 4 ist der Arretierungsmechanismus als elektrorheologischer Arretierungsmechanismus 40 ausgebildet. Dieser besitzt - analog zur magnetorheologischen Lösung - ein Gehäuse 43, in welchem sich eine elektrorheologische Flüssigkeit 41 befindet, welche die Stifte 25 umgibt. Durch eine Einrichtung zur Erzeugung eines elektrischen Feldes 42 lässit sich ein elektrisches Feld erzeugen, welches auf die elektrorheologische Flüssigkeit einwirkt, so dass diese erstarrt und die Stifte 25 fixiert. 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.
