Description

Die vorliegende Erfindung betrifft eine Flachbett-Bogenstanzmaschine zur Stanz- und/oder Prägebearbeitung von bogenförmigen Materialien aus Papier, Pappe und dergleichen, insbesondere zur Herstellung von Papier- oder Kartonzuschnitten, mit einer Stanzeinrichtung und mit einer Transporteinrichtung, um die zu bearbeitenden Materialbögen durch die Stanzeinrichtung zu transportieren.The present invention relates to a flatbed sheet punching machine for punching and / or embossing of sheet-like materials made of paper, cardboard and the like, in particular for the production of paper or cardboard blanks, with a punching device and with a transport device to the material sheets to be processed by the punching device to transport.

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, the separating of the sheets to be punched, which are then subsequently aligned in an alignment device, taken over by a gripper carriage and exactly in the punching device between a fixed undercounter and a toggle lever or in a singling Exzentergetriebe vertically movable upper table positioned. 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.

Die bekannten Flachbett-Bogenstanzmaschinen, welche beispielsweise von der Anmelderin unter der Serie Dymatrix angeboten werden, besitzen einen zentralen Antrieb, über welchen einerseits eine Transporteinrichtung angetrieben wird, welche die zu bearbeitenden Bögen durch die Maschine transportiert, und der andererseits über Schubstangengetriebe der Stanze nachfolgende Bearbeitungsstationen antreibt. Der Obertisch wird über ein mit dem Hauptantrieb gekoppeltes Exzentergetriebe angetrieben. Da also alle Stationen zentral mit dem Hauptgetriebe mechanisch gekoppelt sind, ist es aufwendig, die Bewegungsabläufe für die einzelnen Bearbeitungsstationen zu verändern.The known flat-bed sheet punching machines, which are offered for example by the applicant under the Dymatrix series, have a central drive, via which on the one hand a transport device is driven, which transports the sheets to be processed through the machine, and the other hand via push rod transmission of the punch subsequent processing stations drives. The upper table is driven by an eccentric gear coupled to the main drive. Thus, since all stations are mechanically coupled centrally with the main gearbox, it is expensive to change the motion sequences for the individual processing stations.

Im Hinblick auf diese Problematik liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine Flachbett-Bogenstanzmaschine der eingangs genannten Art flexibler auszugestalten.In view of this problem, the present invention, the object of a flexible flat bed sheet punching machine of the type mentioned above to design.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass die Stanzeinrichtung einen vom Antrieb der Transporteinrichtung unabhängigen eigenen Antrieb besitzt.This object is inventively achieved in that the punching device has a separate drive from the transport device own drive.

Der Erfindung liegt damit die Überlegung zu Grunde, die Stanzeinrichtung mit einem unabhängigen eigenen Antrieb zu versehen, der es gestattet, die Stanzgeschwindigkeit und die Stanzkraft individuell auf die jeweiligen Bedürfnisse einzustellen. Auf diese Weise wird ein aufwendiges Umrüsten der Stanzeinrichtung oder ein mehrmaliges Bearbeiten eines Bogens überflüssig.The invention is therefore based on the consideration to provide the punching device with an independent own drive, which allows to set the punching speed and the punching force individually to the respective needs. In this way, a complicated conversion of the punching device or a multiple processing of a sheet is unnecessary.

Gemäß einer bevorzugten Ausführungsform ist vorgesehen, dass die wenigstens eine weitere Bearbeitungseinrichtung ebenfalls einen vom Antrieb der Transportvorrichtung und dem Antrieb der Stanzmaschine unabhängigen eigenen Antrieb besitzt. Sofern mehrere Bearbeitungseinrichtungen vorgesehen sind, ist zweckmäßigerweise jede dieser Bearbeitungseinrichtungen mit einem von dem Antrieb der Stanzeinrichtung, von den Antrieben der anderen Bearbeitungsstationen sowie von dem Antrieb der Transportvorrichtung unabhängigen eigenen Antrieb ausgestattet. Auf diese Weise ist es möglich, auch die weiteren Bearbeitungseinrichtungen beispielsweise zum Einlegen, Vereinzeln und Ausrichten der zu bearbeitenden Materialbögen bzw. zum Ausbrechen des Abfalls und zum Ablegen der ausgestanzten Nutzen individuell auf die jeweiligen Bedürfnisse einzustellen. Da die Bearbeitungseinrichtungen aufgrund ihrer separaten Antriebe unabhängig voneinander sind, können sie nach Art von eigenständigen Modulen ausgebildet sein, die einzeln ausgetauscht oder nachgerüstet werden können.According to a preferred embodiment it is provided that the at least one further processing device also has a separate drive from the drive of the transport device and the drive of the punching machine. If a plurality of processing devices are provided, each of these processing devices is expediently equipped with a separate drive independent of the drive of the punching device, by the drives of the other processing stations and by the drive of the transport device. In this way it is possible to adjust the further processing devices, for example for inserting, separating and aligning the material sheets to be processed or for breaking out the waste and for depositing the punched out benefits individually to the respective needs. Since the processing facilities are independent of each other due to their separate drives, they can be designed in the manner of independent modules that can be replaced or retrofitted individually.

Als besonders vorteilhaft hat es sich heraus gestellt, wenn die Antriebe einen Elektromotor bzw. eine Servo-Motor aufweisen, da bei diesen die Antriebsleistung und damit die Stanzkraft und -geschwindigkeit des Stanzwerkzeugs auf einfache Weise eingestellt werden kann.It has proven to be particularly advantageous if the drives have an electric motor or a servo motor, since in these the drive power and thus the punching force and speed of the punching tool can be adjusted in a simple manner.

In einer weiteren vorteilhaften Ausführungsform sind die einzelnen Antriebe jeweils mit einer Steuereinheit versehen, wobei die Steuereinheiten über eine Verbindung zum Austausch von Daten- und / oder Steuersignalen miteinander verbunden sind. Vorteilhafterweise können die Daten- und / oder Steuersignale entweder direkt untereinander ausgetauscht werden, oder aber auch nach dem Master-/Slave-Betrieb über eine zentrale Steuerung. Beim Master-/Slave-Betrieb kann es jedoch durchaus sinnvoll sein, dass die einzelnen Steuerungen zwar ihre Steuerbefehle von der zentralen Steuerung erhalten, die Datensignale jedoch selbständig empfangen. Hierzu bietet sich vorteilhafterweise an, dass die Verbindung zum Austausch von Daten- und / oder Steuersignalen als Feldbus, vorteilhafterweise als CANopen Bus ausgebildet ist.In a further advantageous embodiment, the individual drives are each provided with a control unit, wherein the control units are connected to each other via a connection for the exchange of data and / or control signals. Advantageously, the data and / or control signals can be exchanged either directly with each other, or even after the master / slave operation via a central controller. However, in master / slave operation, it may well make sense that the individual controllers receive their control commands from the central controller, but receive the data signals independently. For this purpose, advantageously offers that the connection for the exchange of data and / or control signals as a field bus, advantageously designed as a CANopen bus.

Sofern die Stanzeinrichtung der Flachbett-Bogenstanzmaschine mit zwei gegeneinander bewegbaren Tischen ausgerüstet ist, ist es auch möglich, für jeden der beiden Tische einen separaten Antrieb vorzusehen.If the punching device of the flatbed sheet punching machine is equipped with two mutually movable tables, it is also possible to provide a separate drive for each of the two tables.

Hinsichtlich weiterer vorteilhafter Ausgestaltungen der Erfindung wird auf die Unteransprüche sowie die nachfolgende Beschreibung eines Ausführungsbeispiels unter Bezugnahme auf die beiliegende Zeichnung verwiesen. In der Zeichnung zeigt

a flatbed sheet punching machine according to FIG. 1 with a central control

Die in der Figur 1 dargestellte Flachbett-Bogenstanzmaschine, welche zur Stanz- und/oder Prägebearbeitung von bogenförmigen Materialien aus Papier, Pappe und dergleichen und insbesondere bei der Herstellung von Papier- oder Kartonzuschnitten eingesetzt werden kann, umfasst in der Durchlaufrichtung X hintereinander liegend eine Einlege- und Vereinzelungseinrichtung 1, eine Ausrichteinrichtung 2, eine Stanzeinrichtung 3, eine Ausbrecheinrichtung 4, eine Nutzenablageeinrichtung 5 und eine Trennbogen-Zuführeinrichtung 6. Des Weiteren ist an der an der Nutzenablageeinrichtung 5 ein Palettenbahnhof 7 vorgesehen.The flat-bed sheet punching machine shown in FIG. 1, 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, comprises an insert lying one behind the other in the direction of passage X. - And separating device 1, an alignment device 2, a punching device 3, a breakout device 4, a utility storage device 5 and a separation sheet feeder 6. Furthermore, a pallet station 7 is provided at the on the utility storage device 5.

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 separating 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 beispielsweise über einen Elektromotor 13 angetrieben wird.The operation of the upper table 12 is carried out in the usual manner by means of an eccentric 14, which is driven for example via an electric motor 13.

Im Anschluss an die 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 Ausbrechereinrichtung 4 eingeschobenen, behälterartigen Wagen 15 fallen.Subsequent to 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 breaking-out device 4.

Hinter der Ausbrecheinrichtung 4 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.Behind the breakout device 4 is the depositing device 5, in which the sheet is either simply stored or at the same time there is a separation of the individual benefits, 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.

Wie in der Zeichnung gut erkennbar ist, sind die Einlege- und Vereinzelungseinrichtung 1, die Stanzeinrichtung 3, die Ausbrecheinrichtung 4 und die Ablegeeinrichtung 5 jeweils mit eigenen Antrieben beispielsweise in Form von Elektromotoren 13, 16, 17, 18 versehen, welche von einander und von dem nur schematisch dargestellten Antrieb 19 der Transporteinrichtung unabhängig sind. So kann die Motorleistung und damit auch die zur Verfügung stehende Antriebskraft und Antriebsgeschwindigkeit in jeder Bearbeitungsstation 1, 3, 4, 5 individuell nach Bedarf eingestellt werden, wodurch sich aufwendige Umrüstarbeiten bei Produktwechseln vermeiden lassen.As can be clearly seen in the drawing, the inserting and separating device 1, the punching device 3, the breaking-out device 4 and the depositing device 5 are each provided with their own drives, for example in the form of electric motors 13, 16, 17, 18, which depend on each other and on the drive 19 of the transport device shown only schematically are independent. Thus, the engine power and thus the available driving force and drive speed in each workstation 1, 3, 4, 5 are set individually as needed, which can be costly retooling to avoid product changes.

Weiterhin ist aus Fig. 1 erkennbar, dass die einzelnen Antriebe 13, 16, 17, 18 19 jeweils eine Steuereinheit 23, 26, 27, 28, 29 aufweisen. Die Steuereinheiten sind über eine Verbindung 30 zum direkten Austausch von Daten- und / oder Steuersignalen untereinander miteinander verbunden.1 that the individual drives 13, 16, 17, 18, 19 each have a control unit 23, 26, 27, 28, 29. The control units are interconnected via a connection 30 for the direct exchange of data and / or control signals.

In der aus Fig. 2 ersichtlichen Konfiguration erfolgt der Austausch von Daten- und / oder Steuersignalen über eine zentrale Steuerung 31. Hierbei ist es möglich, dass die Steuereinheiten die Daten- und / oder Steuersignale untereinander direkt austauschen und von der zentralen Steuerung 31 zusätzliche Daten- und / oder Steuersignale erhalten, oder dass die einzelnen Steuereinheiten nach dem Master-/Slave-Prinzip mit der zentralen Steuerung zusammen arbeiten.In the configuration shown in FIG. 2, the exchange of data and / or control signals via a central controller 31. It is possible that the control units exchange the data and / or control signals directly with each other and additional data from the central controller 31 - And / or receive control signals, or that the individual control units work according to the master / slave principle with the central control.
