Abstract

The flatbed stamping machine, to stamp or emboss flat paper/cardboard sheets, has a conveyor (10) to move the sheets through the stamping stations. The first stamping station (3) embosses a film on to the sheets and a second station (3') stamps out or embosses the film-covered sheet. The component parts of the machine are independent modules, with their own drives interconnected for the transfer of data and/or control signals.

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. Alternativ sind auch Stanzen bekannt, bei denen der Obertisch fest gelagert ist und der Untertisch vertikal bewegbar ist.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. Alternatively, punching are also known in which the upper table is fixedly mounted and the lower table is vertically movable.

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 auch die einzelnen Bearbeitungsstationen antreibt. Ein Problem, welches mit dem Antrieb des Obertischs der Stanzeinrichtung über ein solches Schubstangengetriebe verbunden ist, besteht darin, dass mittels der Schubstangen lediglich der von dem Obertisch zurück zu legende Weg, nicht jedoch die Stanzkraft und -geschwindigkeit eingestellt werden können. Dies ist insofern nachteilig, als sich beim Ausstanzen vieler kleiner Nutzen aus einem Bogen größere Stanzkräfte ergeben als beim Ausstanzen lediglich eines Nutzens aus einem Bogen. Dieses Problem wird zurzeit dadurch gelöst, dass beim Ausstanzen vieler kleiner Nutzen der Bogen mehrfach durch die Stanzmaschine bewegt wird. Dies ist jedoch mit einem nicht unerheblichen Aufwand verbunden. Des Weiteren ist die Einrichtung der Werkzeuge, wenn beispielsweise Rillen und Stanzen in einem Arbeitsgang erfolgt, ein erheblicher Aufwand.The known flat-bed sheet punching machines, which are offered for example by the applicant under the series Dymatrix, have a central drive, via which on the one hand a transport device is driven, which transports the sheets to be processed by the machine, and on the other hand via push rod transmission and the individual processing stations drives. One problem associated with the drive of the upper table of the punching device via such a push-rod transmission is that by means of the push rods only the path to be laid back from the upper table, but not the punching force and speed, can be adjusted. This is disadvantageous in that when punching out many small benefits from an arc greater punching forces than when punching out only a benefit from a bow. This problem is currently solved by the fact that the sheet is repeatedly moved through the punching machine when punching out many small benefits. However, this is associated with a considerable effort. Furthermore, the device of the tools, if, for example, grooves and punches in one operation, a considerable effort.

Im Hinblick auf diese Problematik liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine Flachbett-Bogenstanzmaschine der eingangs genannten Art so auszugestalten, dass auch Bögen, die sehr hohe Stanzkräfte erfordern, in einem Maschinendurchlauf bearbeitet werden können. Weiterhin sollen die Rüstzeiten reduziert werden.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 even sheets that require very high punching forces can be processed in a machine pass. Furthermore, the set-up times should be reduced.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass der Stanzeinrichtung nachgeordnet wenigstens eine weitere Stanzeinrichtung vorgesehen ist. Dadurch, dass die erfindungsgemäß ausgebildete Stanzmaschine mindestens zwei hintereinander angeordnete Stanzeinrichtungen aufweist, ist sie in der Lage, in einem einzigen Maschinendurchlauf auch solche Materialbögen vollständig zu bearbeiten, die bisher mehrfach durch die Stanzmaschine geführt werden mussten. Des Weiteren können die Arbeitsgänge Stanzen und Rillen auf zwei Arbeitsstationen verteilt werden, was die Einrichtzeit erheblich verkürzen würde. Hierzu wird die zweite Stanzstation als Rillstation ausgebildet.This object is achieved in that the punching device is provided downstream at least one further punching device. Due to the fact that the punching machine designed according to the invention has at least two punching devices arranged one behind the other, it is able to completely machine such material sheets in a single machine pass, which hitherto had to be passed several times through the punching machine. Furthermore, the punching and grooving operations can be distributed to two workstations, which would significantly shorten set-up time. For this purpose, the second punching station is designed as a creasing station.

Des Weiteren besteht die Möglichkeit, mit der ersten Stanzeinrichtung eine Folie auf einen Bogen aufzuprägen und in der zweiten Stanzeinrichtung einen Einpräge- und/oder Ausstanzvorgang vorzunehmen. Damit erlaubt die erfindungsgemäße Stanzmaschine auch komplexe Bearbeitungsvorgänge in einem Maschinendurchlauf.Furthermore, it is possible to impress a foil on a sheet with the first punching device and to carry out an embossing and / or punching process in the second punching device. Thus, the punching machine according to the invention also allows complex machining operations in a machine pass.

In einer bevorzugten Ausführungsform sind die einzelnen Bearbeitungsstationen jeweils als unabhängige Module mit einem eigenen Antrieb ausgebildet. Dies bietet insbesondere in den Stanzstationen den Vorteil, mit unterschiedlich hohen Stanzkräften zu arbeiten.In a preferred embodiment, the individual processing stations are each designed as independent modules with their own drive. This offers the advantage in particular in the punching stations to work with different levels of punching forces.

In einer besonders bevorzugten Ausführungsform weisen die Antriebe jeweils Steuereinheiten auf, die über eine Verbindung zum Austausch von Daten- und/oder Steuersignalen miteinander verbunden sind. Auf diesem Weg wird eine besonders einfache Kommunikation ermöglicht.In a particularly preferred embodiment, the drives each have control units which are connected to one another via a connection for exchanging data and / or control signals. In this way a particularly simple communication is made possible.

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

With regard to further advantageous embodiments of the invention, reference is made to the dependent claims and the following description of an embodiment with reference to the accompanying drawings. In the drawing shows
FIG. 1
a flatbed sheet punching machine according to the present invention.

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 weitere Stanzeinrichtung 3', die auch als Rilleinrichtung oder Prägeeinrichtung ausgebildet sein kann, 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 Figure 1, which are 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 can, in the passage direction X one behind the other lying an insertion and separation device 1, an alignment 2, a punching device 3, a further punching device 3 ', which can also be designed as a creasing or embossing device, a breakout device 4, a utility storage device 5 and a separation sheet -Zuführeinrichtung 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 wird.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 Page and front marks are aligned accurately.

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, 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, 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 mit dem zentralen Antrieb der Stanzmaschine verbunden ist, der auch die weiteren Bearbeitungsstationen antreibt.The operation of the upper table 12 is carried out in the usual manner by means of an eccentric 14, which is connected to the central drive of the punching machine, which also drives the other processing stations.

Hinter der Stanzeinrichtung 3 ist eine weitere, zweite Stanzeinrichtung 3', die auch als Rilleinrichtung oder Prägeeinrichtung ausgebildet sein kann, vorgesehen, welche hier den gleichen Aufbau hat wie die erste Stanzeinrichtung 3, aber auch unterschiedlich ausgebildet sein kann.Behind the punching device 3 is a further, second punching device 3 ', which may also be designed as a groove or embossing means provided, which here has the same structure as the first punching device 3, but may also be designed differently.

Im Anschluss an die zweite 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 second punching device 3 ', the breaking-out device 4 is provided, in which the unwanted waste pieces produced during the punching process are pushed downwards out of the sheet, as a result of which these waste pieces 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.

Dadurch, dass die Stanzmaschine mindestens zwei hintereinander angeordnete Stanzeinrichtungen 3, 3'aufweist, ist sie in der Lage, in einem einzigen Maschinendurchlauf auch solche Materialbögen vollständig zu bearbeiten, die bisher mehrfach durch die Stanzmaschine geführt werden mussten. Wenn beispielsweise viele Nutzen aus einem Bogen ausgestanzt werden sollen, können diese Nutzen in der ersten Stanzeinrichtung 3 vorgestanzt und in der zweiten Stanzeinrichtung 3' dann ausgestanzt werden. In diesem Fall können die beiden Stanzeinrichtungen 3, 3' in gleicher Weise mit Werkzeugen bestückt sein.Due to the fact that the punching machine has at least two punching devices 3, 3 'arranged one behind the other, it is able to completely machine such material sheets in a single machine pass, which hitherto had to be passed several times through the punching machine. If, for example, many benefits are to be punched out of a sheet, these benefits can be pre-punched in the first punching device 3 and then punched out in the second punching device 3 '. In this case, the two punching devices 3, 3 'can be equipped in the same way with tools.

Des Weiteren besteht die Möglichkeit, mit der ersten Stanzeinrichtung 3 eine Folie auf einen Bogen aufzuprägen und in der zweiten Stanzeinrichtung 3' an dem mit der Folie versehenen Bogen einen Einpräge- und/oder Ausstanzvorgang vorzunehmen. Damit erlaubt die erfindungsgemäße Stanzmaschine bei entsprechender Ausstattung der Stanzeinrichtungen 3, 3' auch komplexe Bearbeitungsvorgänge in einem Maschinendurchlauf.Furthermore, it is possible to use the first punching device 3 to apply a film to a sheet and to perform an embossing and / or punching process in the second punching device 3 'on the sheet provided with the film. Thus, the punching machine according to the invention with appropriate equipment of the punching devices 3, 3 'also allows complex machining operations in a machine pass.

Die einzelnen Bearbeitungsstationen 1, 2, 3, 3', 4, 5, 6, 10 der Flachbett-Bogenstanze können als unabhängige Module ausgebildet sein, was einen besonders flexiblen Einsatz der Stationen ermöglicht. Hierzu sind sie jeweils mit nicht näher dargestellten eigenen Antrieben ausgestattet. Um die Flexibilität weiter zu erhöhen, können die Antriebe jeweils nicht näher dargestellte Steuereinheiten aufweisen, die über eine Verbindung zum Austausch von Daten- und / oder Steuersignalen miteinander verbunden sind.The individual processing stations 1, 2, 3, 3 ', 4, 5, 6, 10 of the flat-bed sheet punch can be designed as independent modules, which allows a particularly flexible use of the stations. For this they are each with their own not shown Drives equipped. In order to further increase the flexibility, the drives may each have control units not shown in detail, which are connected to one another via a connection for exchanging data and / or control signals.

Im Ausführungsbeispiel nach Fig. 1 sind zwei Stanzstationen unmittelbar hintereinander dargestellt. Es können jedoch auch mehr als zwei Stanzstationen sein. Die Stanzstationen können zwar, müssen aber nicht, unmittelbar hintereinander angeordnet sein.In the embodiment of FIG. 1, two punching stations are shown directly behind one another. However, it can also be more than two punching stations. Although the punching stations can, but need not, be arranged directly behind one another.

Darüber hinaus kann die Stanzmaschine auch noch mit weiteren Ausbrecheinrichtungen versehen sein. Dies hätte den Vorteil, dass die benötigte Kraft für die Ausbrechwerkzeuge reduziert werden kann, sobald die Grenzbereiche erreicht werden.In addition, the punching machine can also be provided with other breaking devices. This would have the advantage that the required force for the stripping tools can be reduced as soon as the border areas are reached.

Weiterhin ist es möglich, weitere Nutzenablageeinrichtungen vorzusehen. Diese könnten beispielsweise als Ausschleusestationen oder zur Probeentnahme genutzt werden.Furthermore, it is possible to provide further utility storage facilities. These could be used for example as Ausschleusestationen or for sampling.
