Als Stanzen wird das Schneiden mit in sich geschlossenen, geometrischen Zuschnittsformen bezeichnet, die kreisförmig, oval oder mehreckig sowie Fantasieformen aller Art sein können. Auch die in der Druckweiterverarbeitung geübten Praktiken wie Stanzen mit Locheisen, Ecken abstoßen und Register stanzen werden zu diesem Bereich gezählt. Die Stanzung erfolgt gegen eine Stanzunterlage oder gegen Stempel, teilweise sind es auch Schervorgänge (vgl. Druckweiterverarbeitung, Ausbildungsleitfaden für Buchbinder, Bundesverband Druck e. V. 1996, Seite 351 ff .).As punching the cutting is referred to as closed, geometric blank forms that can be circular, oval or polygonal as well as fantasy shapes of all kinds. Even the practices practiced in print finishing such as punching with punch, repel corners and register punching are counted to this area. The punching takes place against a punching pad or against punches, in some cases it is also shearing operations (cf. Postpress, training manual for bookbinders, Bundesverband Druck e. V. 1996, page 351 ff .).

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 Ausführungen 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.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 designs (such as packaging for cosmetics, cigarettes, pharmaceuticals, foodstuffs, etc.), special requirements are not only placed on the packaging materials themselves, but punching tools are also required for optimum results lowest tolerances and extremely precise and reliable working punching machines required.

Diesen Ansprüchen wird das Flachbettstanzen am besten gerecht. Dabei werden die gedruckten und auf einer Palette gestapelten Bogen der Stanzmaschine zugeführt. In der Maschine erfolgt in einer Vereinzelungseinrichtung zunächst die Vereinzelung der zu stanzenden Bogen, die dann anschließend in einer Ausrichteinrichtung passgenau ausgerichtet, von einem Greiferwagen übernommen und exakt in der Stanzeinrichtung zwischen einem fest gelagerten Untertisch und einem über ein Kniehebel- oder Exzentergetriebe vertikal bewegbaren Obertisch positioniert. Eine derartige Flachbettstanze ist beispielsweise aus der DE 30 44 083 A1 bekannt.Flatbed punching best meets these demands. The printed sheets stacked on a pallet are fed to the punching machine. In the machine takes place in a separating device initially the separation of punching sheet, which then then aligned accurately in an alignment, taken from a gripper carriage and positioned exactly in the punching device between a fixed undercounter and a vertical over a toggle lever or eccentric upper table. Such a flat bed punch is for example from the DE 30 44 083 A1 known.

Die beiden Tische sind mit Schneid- und Rillwerkzeugen bzw. entsprechenden Gegenwerkzeugen bestückt, mit denen aus den taktweise zwischen die Tischflächen 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 Nutzentrennungseinrichtung separiert werden.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 surfaces bows and simultaneously 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 benefit separation device.

Aus der DE 20 2004 018 151 U1 ist eine Flachbett-Bogenstanzmaschine mit mehreren Bearbeitungsstationen bekannt. An einer Seite der Maschine sind den Bearbeitungsstationen jeweils Magazine zugeordnet, in denen entsprechende Werkzeuge gelagert sind. Mittels entsprechender Übergabevorrichtungen können die Werkzeuge gewechselt werden.From the DE 20 2004 018 151 U1 is a flatbed sheet punching machine with several processing stations known. On one side of the machine, the processing stations are each assigned magazines in which appropriate tools are stored. By means of appropriate transfer devices, the tools can be changed.

Eine bekannte Flachbett-Bogenstanzmaschine, welche aus der DE-A-37 12 510 bekannt ist, ist zusätzlich mit einer Handhabungseinrichtung ausgestattet, um einer Bedienungsperson einen Werkzeugwechsel an den einzelnen Bearbeitungsstationen der Stanzmaschine zu erleichtern.

Der Handhabungseinrichtung ist ein Werkzeugmagazin zugeordnet, aus welchem die Werkzeuge entnommen bzw. in dem die nicht mehr benötigten Werkzeuge abgelegt werden können. Das Werkzeugmagazin ist zusammen mit der Handhabungseinrichtung verfahrbar und kann insbesondere aus dem Bedienungsbereich der Maschine heraus bewegt werden, wenn es nicht benötigt wird.A well-known flatbed sheet punching machine, which from the DE-A-37 12 510 is known, is additionally equipped with a handling device to facilitate an operator tool change at the individual processing stations of the punching machine. The handling device is designed here as a semi-automatic lifting device, which is arranged on the operating platform of the machine and movable along it. The operator has the option of positioning the handling device at each of the processing stations and then extending a lifting fork to grip and position a tool. The handling device is associated with a tool magazine, from which the tools removed or in which the tools no longer required can be stored. The tool magazine can be moved together with the handling device and in particular can be moved out of the operating range of the machine when it is not needed.

An der bekannten Flachbett-Bogenstanzmaschine wird als nachteilig angesehen, dass sich der Werkzeugwechsel aufwendig gestaltet.On the known flatbed sheet punching machine is considered disadvantageous that the tool change designed consuming.

Im Hinblick auf diese Problematik liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine Flachbett-Bogenstanzmaschine der eingangs genannten Art so auszugestalten, dass sie einfach bedient und insbesondere umgerüstet werden kann.In view of this problem, the present invention, the object of a flat bed sheet punching machine of the type mentioned in such a way that it can be easily operated and in particular can be retrofitted.

Diese Aufgabe ist gemäß Anspruch 1 gelöst. Dadurch, dass die Handhabungseinrichtung erfindungsgemäß auf der Antriebsseite der Maschine vorgesehen ist, kann sie einfach ausgebildet sein und effizient arbeiten. Dies ist im Wesentlichen dadurch bedingt, dass das Bedienungspodest der Maschine von ihr nicht mehr übergriffen zu werden braucht, wenn ein Werkzeugwechsel stattfinden soll. Des Weiteren wird das Bedienungspodest beim Werkzeugwechsel auch nicht durch die Werkzeugwechseleinrichtung blockiert, so dass das Bedienungspodest weiterhin zu Wartungszwecken oder zur Bedienung einer anderen Maschine verwendet werden kann, wenn ein Werkzeugwechsel an der Stanzmaschine stattfindet. Darüberhinaus kann die Werkzeugwechseleinrichtung aus dem Weg gefahren werden, wenn kein Werkzeugwechsel stattfindet.This object is achieved according to claim 1. The fact that the handling device is provided according to the invention on the drive side of the machine, it can be easily formed and work efficiently. This is essentially due to the fact that the operating platform of the machine need not be overridden by her when a tool change is to take place. Furthermore, the operator platform during tool change is not blocked by the tool changing device, so that the operator platform can continue to be used for maintenance purposes or to operate another machine when a tool change takes place at the punching machine. In addition, the tool changing device can be moved out of the way, if no tool change takes place.

Weiterhin ist es möglich, die Werkzeugwechseleinrichtung für einen Werkzeugwechsel an mehreren Bearbeitungseinrichtungen zu nutzen.Furthermore, it is possible to use the tool changing device for a tool change at several processing facilities.

In einer besonders bevorzugten Ausführungsform weist die rlachbett-Bogenstanze zum Wechseln der Werkzeuge mindestens zwei Werkzeugwechseleinrichtungen auf. Eine davon ist entlang der Bedienseite der Maschine verfahrbar angeordnet und dient dazu, die Maschine mit neuen Werkzeugen zu bestücken. Die andere Werkzeugwechseleinrichtung ist entlang der der Bedienseite gegenüberliegenden Antriebsseite der Maschine verfahrbar angeordnet und dient zur Aufnahme von Werkzeugen, die aus der Maschine entfernt werden.In a particularly preferred embodiment, the rlachbett sheet punch for changing the tools on at least two tool changing devices. One of them can be moved along the operating side of the machine and serves to equip the machine with new tools. The other tool changer can be moved along the drive side of the machine opposite the operator side arranged and used to hold tools that are removed from the machine.

Vorteilhafter Weise haben die Werkzeugwechseleinrichtungen Magazine zur Aufnahme der Werkzeuge. Den unterschiedlichen Werkzeugen wie Stanzwerkzeug, Ausbrechwerkzeug, Nutzentrennwerkzeug etc. sind hierbei feste Magazine in einer definierten Höhe zugeordnet. Zum Wechsel dieser Werkzeuge können diese in den einzelnen Bearbeitungseinrichtungen auf eine definierte Wechselhöhe gefahren werden. Diese Wechselhöhe entspricht der entsprechenden Magazinhöhe in der Werkzeugwechseleinrichtung. Bei dieser Konstellation ist es besonders einfach, mittels einer entsprechenden Vorrichtung an den einzelnen Bearbeitungsstationen und / oder der Werkzeugwechseleinrichtung den Wechsel der Werkzeuge vollautomatisch durchzuführen.Advantageously, the tool changing devices have magazines for receiving the tools. The different tools such as punching tool, stripping tool, blanking tool, etc. are assigned here fixed magazines in a defined height. To change these tools, these can be moved in the individual processing facilities to a defined change height. This change height corresponds to the corresponding magazine height in the tool changing device. In this constellation, it is particularly easy to carry out the change of tools fully automatically by means of a corresponding device to the individual processing stations and / or the tool changing device.

Des Weiteren ist an der an der Nutzenablageeinrichtung 5 ein Palettenbahnhof 7 vorgesehen. Entlang der Maschinenvorderseite erstreckt sich ein Podest P für eine Bedienungsperson, das an beiden Enden über eine Treppe T betreten werden kann.In the drawing, a flat-bed sheet punching machine is shown, which can be used for punching and / or embossing of sheet-like materials made of paper, cardboard and the like and in particular in the production of paper or cardboard blanks. The machine comprises in the direction of passage X one behind the other lying an insertion and separation device 1, an alignment device 2, a punching device 3, a breakout device 4, a utility storage device 5 and a Separation sheet feeding device 6. Furthermore, a pallet station 7 is provided at the on the use storage device 5. Along the front of the machine extends a pedestal P for an operator who can be entered at both ends via a staircase T.

In der Einlege- und Vereinzelungseinrichtung 1 werden die zu bearbeitenden Bögen gestapelt zur Verfügung gestellt und von dem Stapel über einen Saugkopf 8 einzeln von oben entnommen und auf ein Transportband 9 abgelegt, welches den Bogen der Ausrichteinrichtung 2 zuführt, wo dieser beispielsweise an drei Punkten mit Seiten- und Frontmarken passgenau ausgerichtet werden.In the loading and singling device 1, the sheets to be processed stacked provided and removed from the stack via a suction head 8 individually from above and placed on a conveyor belt 9, which feeds the sheet of the alignment device 2, where this example, at three points with Side and front brands are aligned accurately.

Bei der Bearbeitung von endlosen Bahnen wird anstelle der Einlegeeinrichtung 1 eine Abrolleinrichtung, eventuell mit nachfolgenden Querschneidern, eingesetzt.In the processing of endless webs, instead of the insertion device 1, a unwinding device, possibly with subsequent cross-cutters, is used.

In der Ausrichtstation 2 wird der ausgerichtete Bogen von einem Greifer eines Transportsystems, von welchem in der Zeichnung lediglich die Transportkette 10 gezeigt ist, übernommen, welches den Bogen getaktet und präzise ausgerichtet durch die weiteren Bearbeitungsstationen 3, 4, 5, 6 führt.In the alignment station 2, the aligned sheet is taken over by a gripper of a transport system, of which in the drawing only the transport chain 10 is shown, which clocks the sheet and precisely aligned by the other processing stations 3, 4, 5, 6 leads.

Der Ausrichtstation 2 nachgeordnet ist die Stanzeinrichtung 3, welche einen am Maschinengestell G fest gelagerten Untertisch 11 und einen vertikal bewegbaren Obertisch 12 aufweist. Dabei trägt der Obertisch 12 ein Stanzmesser und der Untertisch eine Stanzgegenplatte.The alignment station 2 is arranged downstream of the punching device 3, which has a fixedly mounted on the machine frame G under table 11 and a vertically movable upper table 12. The upper table 12 carries a punching knife and the undercounter a stamped counter plate.

Die Betätigung des Obertisches 12 erfolgt in üblicher Weise mittels eines Exzentergetriebes 14, welches über ein nicht dargestelltes Schubstangengetriebe mit einem zentralen Antrieb der Stanzmaschine verbunden ist, welcher auch die weiteren Bearbeitungsstationen antreibt. Der Stanzeinrichtung 3 ist weiterhin eine Werkzeugwechseleinrichtung 3a zugeordnet. Diese Werkzeugwechseleinrichtung 3a ist an der dem Podest P gegenüber liegenden Rückseite oder Antriebseite der Maschine stationär angeordnet und dient dazu, die Stanzwerkzeuge der Stanzeinrichtung 3 vollautomatisch auszuwechseln. Hierzu ist die Werkzeugwechseleinrichtung 3a mit einem Werkzeugmagazin ausgestattet, in welchem nicht mehr benötigte Werkzeuge abgelegt bzw. aus dem benötigte Werkzeuge entnommen werden können.The operation of the upper table 12 is effected in the usual manner by means of an eccentric 14, which is connected via a not shown push rod transmission with a central drive of the punching machine, which also drives the other processing stations. The punching device 3 is further associated with a tool changing device 3a. This tool changing device 3 a is arranged stationarily on the rear side or drive side of the machine opposite the pedestal P and serves to replace the punching tools of the punching device 3 fully automatically. For this purpose, the tool changing device 3a is equipped with a tool magazine, in which tools that are no longer needed can be stored or removed from the required tools.

Hinter der Stanzeinrichtung 3 ist die Ausbrecheinrichtung 4 vorgesehen, in welcher die beim Stanzvorgang entstehenden, nicht benötigten Abfallstücke aus dem Bogen nach unten heraus gestoßen werden, wodurch diese Abfallstücke in einen unter der Ausbrecheinrichtung 4 eingeschobenen, behälterartigen Wagen 15 fallen.Behind the punching device 3, the breaking-out device 4 is provided, in which the unwanted waste pieces produced during the punching process are pushed out of the sheet downwards, whereby these pieces of waste fall into a container-like carriage 15 inserted below the break-out device 4.

Der Ausbrecheinrichtung 4 nachgeordnet befindet sich die Ablegeeinrichtung 5, in welcher der Bogen entweder nur einfach abgelegt wird oder aber gleichzeitig eine Trennung der einzelnen Nutzen erfolgt, wobei Trennwerkzeuge hier nicht näher dargestellter Art verwendet werden können. Die Bögen können hier auf Paletten abgelegt und aufgestapelt werden, welche in dem Palettenbahnhof 7 untergebracht sind, so dass nach Erreichen einer bestimmten Stapelhöhe die Palette mit den aufgestapelten Bögen aus dem Bereich der Stanzmaschine weggefahren werden kann.Downstream of the stripping device 4 is the depositing device 5, in which the sheet is either simply stored or at the same time a separation of the individual benefits takes place, with separating tools can not be used here in more detail. The sheets can be stored here on pallets and stacked, which are housed in the pallet station 7, so that after reaching a certain stack height, the pallet can be moved away with the stacked sheets from the field of punching machine.

Dadurch, dass die Stanzeinrichtung 3 mit einer Werkzeugwechseleinrichtung 3a versehen ist, kann ein Werkzeugwechsel an der Stanzeinrichtung 3 vollautomatisch und in der Folge schnell und effizient ausgeführt werden. Des Weiteren bleibt auch das Podest P während der Umrüstung frei, so dass die Bedienungsperson andere Arbeiten ausführen kann. Es besteht natürlich die Möglichkeit, auch die anderen Bearbeitungseinrichtungen 1, 4, 5 mit einer entsprechenden automatischen Werkzeugwechseleinrichtung auszustatten. Auch ist es möglich, den Bearbeitungseinrichtungen 1, 3, 4, 5 eine gemeinsame Handhabungseinrichtung zuzuordnen, welche entlang der Maschinenrückseite verfahrbar ist und es ermöglicht, an allen Bearbeitungseinrichtungen 1, 3, 4, 5 einen Werkzeugwechsel vorzunehmen.Characterized in that the punching device 3 is provided with a tool changing device 3a, a tool change to the punching device 3 can be carried out fully automatically and consequently quickly and efficiently. Furthermore, the pedestal P remains free during the conversion, so that the operator can perform other work. Of course, it is possible to equip the other processing devices 1, 4, 5 with a corresponding automatic tool changing device. It is also possible to assign to the processing devices 1, 3, 4, 5 a common handling device which can be moved along the machine rear side and makes it possible to carry out a tool change on all processing devices 1, 3, 4, 5.

In Figur 3 ist eine alternative Möglichkeit des Werkzeugwechsels dargestellt. Die Flachbettbogenstanzmaschine 20 weist sowohl an ihrer Bedienseite als auch an ihrer der Bedienseite gegenüber liegenden Antriebsseite mindestens je eine verfahrbare Werkzeugwechseleinrichtung 3a, 3b auf. Diese sind entlang der Bedienseite bzw. Antriebsseite in Verfahrrichtung F1 und F2 verfahrbar. Die Werkzeugwechseleinrichtung 3b dient hierbei zur Bestückung der Maschine mit neuen Werkzeugen gemäß Wechselrichtung W1, nachdem die alten Werkzeuge aus der Maschine in Wechselrichtung W2 in die Werkzeugwechseleinrichtung 3a transportiert wurden.In FIG. 3 an alternative possibility of tool change is shown. The flatbed sheet punching machine 20 has at least one moveable tool changing device 3a, 3b both on its operating side and on its drive side opposite the operating side. These can be moved along the operator side or drive side in the travel direction F 1 and F 2 . The tool changer 3b serves here for equipping the machine with new tools according to change direction W 1 , after the old tools were transported from the machine in the direction of exchange W 2 in the tool changer 3a.

Um einen vollautomatischen Wechsel der Werkzeuge zu gewährleisten, sind die einzelnen Bearbeitungsstationen und / oder die Werkzeugwechseleinrichtungen 3a, 3b mit nicht näher dargestellten bekannten Vorrichtungen zum Wechsel der Werkzeuge versehen.In order to ensure a fully automatic change of tools, the individual processing stations and / or the tool changing devices 3a, 3b are provided with known devices for changing the tools, not shown.
