Abstract
Description
Die Erfindung betrifft eine Bogenstanz- und / oder -prägestation gemäß dem Oberbegriff von Anspruch 1 und ein System, umfassend ein eine Flachbett-Bogenstanzmaschine und eine Druckluftpistole gemäß Anspruch 9.The invention relates to a sheet punching and / or embossing station according to the preamble of
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 Kunststoff, Folienmaterial, 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. Plastic, film, paper, cardboard, cardboard or corrugated board packaging materials are mainly stamped 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, Prägen, Ausbrechen, ggfs. Nutzentrennen 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. Ein jeweiliger Greiferwagen besitzt eine Greiferbrücke, an der Greifer befestigt sind, die die Bögen an einem vorderen Ende ergreifen. Ein Greiferwagen besitzt weiterhin seitliche Fahrwagen, welche mit endlosen Ketten des Transportsystems verbunden sind und wodurch die Greiferwagen 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, insbesondere Stanz-, Ausbrech- und Nutzentrennstation, ermöglicht.In known sheet punching and embossing machines, which are used for punching, embossing, breaking, if necessary. Nutzentrennen and storing sheets of paper, cardboard and the same, it is known to move the sheets by means of gripper carriage through the individual stations of the machine. A respective gripper carriage has a gripper bridge, to which grippers are fixed, which grasp the arches at a front end. A gripper carriage further has lateral carriages, which are connected to endless chains of the transport system and whereby the gripper carriage to be moved by the machine. By this type of movement of the sheets through the machine, a continuous work in the individual successively arranged stations of the machine, in particular punching, break-away and Nutzentrennstation allows.

Aus der
Weiterhin bekannt ist die Verwendung von Exzenterrahmen, welche das Werkzeug durch Verdrehen von Exzentern Klemmen. Nachteilig daran ist dass die Werkzeuge ungleichmäßig gespannt werden.Also known is the use of eccentric frames, which clamp the tool by rotating eccentrics. The disadvantage of this is that the tools are stretched unevenly.
Die
Nachteilig an der Verwendung von Hydraulik ist, dass eine aufwändige Abdichtung der Hydraulikleitungen erforderlich ist. Besonders auf Grund der Hubbewegung des Werkzeuges ist dies schwierig. Wenn es zu Leckage kommt und durch die Bogenstanz- und -prägemaschine Produkte für die Lebensmittelindustrie hergestellt werden, so können die Produkte auch bei nur geringer Verunreinigung nicht verwendet werden.The
A disadvantage of the use of hydraulics is that a complex sealing of the hydraulic lines is required. This is particularly difficult because of the lifting movement of the tool. If leakage occurs and the sheet punching and embossing machine produces products for the food industry, the products can not be used even with only minor contamination.
Aufgabe der vorliegenden Erfindung ist es, eine Bogenstanz- und / oder -prägestation zu schaffen, welche bei einfachem Aufbau und einfacher Handhabung ein sicheres Klemmen eines Stanz- und / oder Prägewerkzeugs ermöglicht und dabei die Nachteile der aus dem Stand der Technik bekannten Klemmeinrichtungen vermeidet.Object of the present invention is to provide a Bogenstanz- and / or -prägestation which allows a simple construction and ease of use secure clamping a punching and / or embossing tool and thereby avoids the disadvantages of the known from the prior art clamping devices.
Gelöst wird diese Aufgabe durch eine Bogenstanz- und / oder -prägestation mit den Merkmalen von Anspruch 1. Die erfindungsgemäße Bogenstanz- und / oder -prägestation für eine Flachbett-Bogenstanzmaschine mit einem oberen Tiegel und einem unteren Tiegel, wobei einer der beiden Tiegel hubbewegt ist, besitzt einen Schließrahmen, welcher mit dem oberen Tiegel verbunden ist, und ein Stanz- und / oder Prägewerkzeug hält. Zur Bearbeitung von Bogen aus Papier, Pappe, Kunststoff und dergleichen durch die Bogenstanz- und / oder -prägestation wird ein jeweiliger Bogen in einer Bogentransportrichtung zwischen den Tiegeln hindurchbewegt. Erfindungsgemäß besitzt der Schließrahmen eine Federklemmeinrichtung z.B. mit Spiral-Druckfedern, zum permanenten Klemmen des Stanz- und / oder Prägewerkzeugs und weiter eine Pneumatikeinrichtung zum Aufheben der Klemmung des Stanz- und / oder Prägewerkezeugs. In vorteilhafter Weise besitzt die Pneumatikeinrichtung einen von außerhalb der Bogenstanz- und / oder -prägestation zugänglichen Druckluftversorgungseingang zum temporären Zuführen einer Druckluft. Dies hat den Vorteil, dass nur dann eine Kraft von außen aufgebracht werden muss, wenn die Klemmung des Werkzeugs aufgehoben werden soll. Weiter vorteilhaft ist, dass die Verwendung von Druckluft im Gegensatz zu einem Hydraulikfluid unkritisch bezüglich der Verarbeitung von Lebensmittelverpackungen ist. Die erfindungsgemäße Bogenstanz- und / oder -prägestation verfügt über keine permanente Druckluftversorgung, vielmehr wird über den Druckluftversorgungseingang nur kurzzeitig eine Druckluft zugeführt, welche dann in der Pneumatikeinrichtung wirkt. In vorteilhafter Weise sind somit - im Fall des bewegten oberen Tiegels - keine Druckluftzuleitungen erforderlich, welche die Hubbewegung des Werkzeugs mitmachen. Dadurch wird eine einfachere und kostengünstigere Konstruktion der Bogenstanz- und / oder -prägestation ermöglicht.This object is achieved by a sheet punching and / or -prägestation with the features of
In vorteilhafter Weiterbildung der erfindungsgemäßen Bogenstanz- und / oder Prägestation steht eine jeweilige Federklemmeinrichtung mit je mindestens Pneumatikator, z.B. einem Pneumatikzylinder oder einem kolbenlosen Pneumatikantrieb wie einer Pneumatikschiene - nachfolgend kurz als Pneumatikzylinder bezeichnet - in einer Wirkverbindung, wobei ein jeweiliger Pneumatikzylinder Teil der Pneumatikeinrichtung ist. Der jeweilige mindestens eine Pneumatikzylinder kann so der Federkraft der Federklemmeinrichtung entgegenwirken, so dass die Klemmung des Werkzeugs aufgehoben werden kann.In an advantageous embodiment of the sheet punching and / or embossing station according to the invention is a respective spring clamping device, each with at least pneumatic, e.g. a pneumatic cylinder or a piston-free pneumatic drive such as a pneumatic rail - hereinafter referred to briefly as a pneumatic cylinder - in an operative connection, wherein a respective pneumatic cylinder is part of the pneumatic device. The respective at least one pneumatic cylinder can thus counteract the spring force of the spring clamping device, so that the clamping of the tool can be canceled.
In einer besonders vorteilhaften Weiterbildung der erfindungsgemäßen Station verfügt der Schließrahmen über mindestens eine erste Federklemmeinrichtung zum Klemmen des Stanz- und / oder Prägewerkzeugs in Bogentransportrichtung und über mindestens eine zweite Federklemmeinrichtung zum Klemmen des Stanz- und / oder Prägewerkzeugs senkrecht zur Bogentransportrichtung. Der mindestens ersten und mindestens zweiten Federklemmeinrichtung ist jeweils ein mit dem Druckluftversorgungseingang verbundener Luftkanal zugeordnet. In anderen Worten: Ein jeweiliger Luftkanal verbindet den Druckluftversorgungseingang mit den einer jeweiligen ersten und zweiten Federklemmeinrichtung zugeordneten Pneumatikzylindern. Da jede Federklemmeinrichtung mit dem Druckluftversorgungseingang verbunden ist, kann in vorteilhafter Weise durch Zuführen einer Druckluft die Klemmung des Werkzeugs schnell gelöst und die Handhabung beim Werkzeugwechsel einfach gehalten werden.In a particularly advantageous development of the station according to the invention, the closing frame has at least one first spring clamping device for clamping the punching and / or embossing tool in the sheet transport direction and at least one second spring clamping device for clamping the punching and / or embossing tool perpendicular to the sheet transport direction. The at least first and at least second spring clamping device is assigned in each case one connected to the compressed air supply inlet air duct. In other words, a respective air channel connects the compressed air supply input to the pneumatic cylinders associated with a respective first and second spring clamping device. Since each spring clamp is connected to the compressed air supply input, in Advantageously, by applying compressed air, the clamping of the tool quickly solved and the handling when changing tools are kept simple.
In vorteilhafter Weiterbildung besitzt jeder Luftkanal ein Rückschlagventil. Dadurch wird der Druck in den Luftkanälen und den Pneumatikzylindern gehalten.In an advantageous embodiment, each air duct has a check valve. As a result, the pressure in the air ducts and the pneumatic cylinders is maintained.
In vorteilhafter Weiterbildung besitzt jeder Luftkanal ein mit der Umgebung verbundenes steuerbares Drosselventil zum Abbauen des Drucks im jeweiligen Luftkanal. Dies hat den Vorteil, dass dadurch die Klemmkraft auf das Werkzeug senkrecht zur Bogentransportrichtung, d. h. in Seitenrichtung, und in Bogentransportrichtung, d. h. in Umfangsrichtung, wirksam werden kann und ein Verspannen im Sinne eines Verformens des Werkzeugs bzw. des Schließrahmens so verhindert wird.In an advantageous embodiment, each air duct has a controllable throttle valve connected to the environment for reducing the pressure in the respective air duct. This has the advantage that thereby the clamping force on the tool perpendicular to the sheet transport direction, d. H. in the lateral direction, and in the sheet transport direction, d. H. in the circumferential direction, can be effective and a distortion in the sense of deforming the tool or the closing frame is prevented.
In einer weiteren Ausführungsform besitzt der Schließrahmen der Bogenstanz- und / oder -prägestation mechanische Justierelemente, insbesondere Justierschrauben zum zusätzlichen Justieren des Stanz- und / oder Prägewerkzeuges im Schließrahmen. Dadurch können bereits in ihrer Geometrie verzogene Werkzeuge manipuliert und nachjustiert werden.In a further embodiment, the closing frame of the sheet punching and / or embossing station has mechanical adjusting elements, in particular adjusting screws for additional adjustment of the punching and / or embossing tool in the closing frame. As a result, already distorted in their geometry tools can be manipulated and readjusted.
In einer weiteren vorteilhaften Ausführungsvariante besitzt der Schließrahmen der Bogenstanz- und / oder -prägestation ein Zentrierelement zum Zentrieren des Stanz- und /oder Prägewerkzeugs im Sinne eines Ausrichtens des Werkzeugs senkrecht zur Bogentransportrichtung.In a further advantageous embodiment variant, the closing frame of the sheet punching and / or embossing station has a centering element for centering the punching and / or embossing tool in the sense of aligning the tool perpendicular to the sheet transport direction.

Die Bögen 6 werden durch einen Anleger 1 von einem Stapel vereinzelt, dem Bogentransportsystem 7 zugeführt und von an Greiferbrücken eines Greiferwagens 8 befestigten Greifern an ihrer Vorderkante ergriffen und in Bogentransportrichtung B intermittierend durch die verschiedenen Stationen 2, 3 und 4 der Stanz- und Prägemaschine 100 hindurchgezogen.
Das Bogentransportsystem 7 besitzt mehrere Greiferwagen 8, sodass mehrere Bögen 6 gleichzeitig in den verschiedenen Stationen 2, 3 und 4 bearbeitet werden können. Die Greiferwagen 8 können von einem Kettenantrieb oder in einer alternativen Ausführungsform durch einen elektromagnetischen Linearantrieb mit Wanderfeldmotoren angetrieben werden, wie beispielsweise in der

Die erfindungsgemäße Bogenstanz- und /oder -prägestation 2 besteht aus einem unteren Tiegel, einem sog. Untertisch 9, und einem oberen Tiegel, einem sog. Obertisch 10. Der Obertisch 10 ist vertikal hin- und herbewegbar gelagert und mit einem Oberwerkzeug 30 mit Stanz- und Rillmessern versehen. Das Oberwerkzeug besitzt einen in den
Der Greiferwagen 8 transportiert den Bogen 6 von der Stanz- und Prägestation 2 in die nachfolgende Ausbrechstation 3, die mit Ausbrechwerkzeugen 21, 23 ausgestattet ist. In der Ausbrechstation 3 werden mit Hilfe der Ausbrechwerkzeuge 21, 23 die nicht benötigten Abfallstücke 11 aus dem Bogen 6 nach unten herausgestoßen, wodurch die Abfallstücke 11 in einen unter der Station eingeschobenen wagenartigen Behälter 12 fallen.The
Von der Ausbrechstation 3 gelangt der Bogen 6 in den Ausleger 4, wo der Bogen 6 entweder nur einfach abgelegt wird, oder aber gleichzeitig eine Trennung der einzelnen Nutzen eines jeweiligen Bogens 6 erfolgt. Dazu besitzt der Ausleger 4 ein Nutzentrennwerkzeug 21, 23. Der Ausleger 4 kann auch eine Palette 13 enthalten, auf der die einzelnen Bögen 6 bzw. Nutzen in Form eines Stapels 14 aufgestapelt werden, so dass nach Erreichen einer bestimmten Stapelhöhe die Palette 13 mit dem Bogenstapel 14 aus dem Bereich der Stanz- und Prägemaschine 100 weggefahren werden kann. Um die Maschine 100 während des Stapeltausches nicht anhalten zu müssen können Hilfsstapeleinrichtungen zum Einsatz kommen.From the breaking station 3, the sheet 6 enters the

Soll eine sich in dem Schließrahmen 31 befindliche Stanzplatte 32 ausgewechselt werden, so wird vom Maschinenbediener die Spitze der Druckluftpistole 80 in den Druckluftversorgungseingang 40 eingeführt und durch Betätigung der Druckluftpistole 80 eine Druckluft in die Kanäle 39.1, 39.2 eingebracht. Diese eingebrachte Druckluft bewirkt, dass die Pneumatikzylinder 33.2 aktiviert werden, der Federkraft der Federn 33.1 entgegenwirken und die Klemmplatten 36 von der Stanzplatte 32 weg auf den Schließrahmen 31 hinzu bewegen. Dadurch wird die Klemmung der Stanzplatte 32 aufgehoben und die Stanzplatte 32 kann vom Maschinenbediener entnommen und durch eine andere Stanzplatte 32 ersetzt werden. Um die neu eingesetzte Stanzplatte 32 wieder im Schließrahmen 31 zu klemmen, sind in den Kanälen 39.1, 39.2 Ventile 35.1, 35.2 vorgesehen, um die Druckluft abzulassen. Die Ventile 35.1 und 35.2 können dabei einzeln angesteuert werden, so dass zuerst das erste Ventil 35.1 angesteuert und der Druck im ersten Kanal 39.1 abgebaut werden kann. Damit verlieren die zugeordneten Pneumatikzylinder 33.1 ihre Wirkung und die Stanzplatte 32 wird aufgrund von der Federklemmkraft der Federklemmeinrichtung 33 in Bogentransportrichtung B geklemmt. Nachfolgend wird das zweite Ventil 35.2 angesteuert und die Druckluft im zweiten Kanal 39.2 abgebaut, so dass hierbei die zugeordneten Pneumatikzylinder 33.2 ihre Wirksamkeit verlieren und die Stanzplatte 32 aufgrund der Federklemmkraft der Federklemmeinrichtungen 33 auch quer zur Bogentransportrichtung B geklemmt wird. Um die Klemmung von Stanzplatten 32, insbesondere von verformten bzw. verzogenen Stanzplatten 32, weiter zu optimieren, sind in dem Schließrahmen 31 Justierschrauben 38 vorgesehen, welche eine zusätzliche Kraft auf die Stanzplatte 32 ausüben können.
