Gattungsgemäßer Stand der Technik ist offenbart in
Diese Druckschrift betrifft eine maschinelle Anordnung, die eine Stanzmaschine zum stanzenden Bearbeiten von Blechen sowie eine Be- und Entladevorrichtung umfasst. Eine stationäre Stanzstation der Stanzmaschine weist ein Stanzoberwerkzeug an einem oberen Gestellschenkel der Stanzmaschine sowie ein dem Stanzoberwerkzeug gegenüberliegendes Stanzunterwerkzeug an einem unteren Gestellschenkel der Stanzmaschine auf. Beidseits des Stanzunterwerkzeugs erstreckt sich jeweils ein Auflagenteil einer horizontalen Werkstückauflage der Stanzmaschine. Zu bearbeitende Werkstücke werden zu Bearbeitungszwecken relativ zu der Stanzstation über die Werkstückauflage bewegt. Dabei übernimmt eine Koordinatenführung der Stanzmaschine die Werkstückbewegung in einer ersten Achsrichtung der horizontalen Werkstückbewegungsebene. In der zweiten Achsrichtung der horizontalen Werkstückbewegungsebene werden die zu bearbeitenden Werkstücke mittels der Werkstückauflage bewegt, die zu diesem Zweck an dem unteren Gestellschenkel der Stanzmaschine beweglich geführt ist.This document relates to a mechanical arrangement comprising a punching machine for punching processing of sheets and a loading and unloading device. A stationary punching station of the punching machine has a punching top tool on an upper frame limb of the punching machine and a punching lower tool lying opposite the punching top tool on a lower frame limb of the punching machine. On both sides of the punching tool, in each case a support part of a horizontal workpiece support of the punching machine extends. Workpieces to be machined are moved over the workpiece support for machining purposes relative to the stamping station. In this case, a coordinate guide of the punching machine assumes the workpiece movement in a first axial direction of the horizontal workpiece movement plane. In the second axial direction of the horizontal workpiece movement plane, the workpieces to be processed are moved by means of the workpiece support, which for this purpose is movably guided on the lower frame limb of the punching machine.
Die Be- und Entladevorrichtung der maschinellen Anordnung gemäß
Nach Abschluss der Bearbeitung eines Werkstücks wird das erstellte Bearbeitungsprodukt mittels der Koordinatenführung der Stanzmaschine an den Rand eines der Auflagenteile der Werkstückauflage bewegt. Die Plattform der Be- und Entladevorrichtung wird seitlich neben der Werkstückauflage der Stanzmaschine in vertikaler Richtung geringfügig unterhalb der Werkstückauflage angeordnet. Mit dem darauf abgelegten Bearbeitungsprodukt verfährt die Werkstückauflage der Stanzmaschine anschließend aus einer Ausgangsposition über die Plattform der Be- und Entladevorrichtung. Nun wird der Greifer der Be- und Entladevorrichtung in horizontaler Richtung zugestellt, bis er den Rand des von der Werkstückauflage der Stanzmaschine gelagerten Bearbeitungsprodukts erfassen kann. Ist das Bearbeitungsprodukt an dem Greifer der Be- und Entladevorrichtung fixiert, verfährt die Werkstückauflage der Stanzmaschine zurück in ihre Ausgangsposition. Dabei wird der betreffende Auflagenteil der Werkstückauflage unter dem Bearbeitungsprodukt herausgezogen und das Bearbeitungsprodukt wird unter Schwerkraftwirkung auf der darunterliegenden Plattform der Be- und Entladevorrichtung abgelegt.After completion of the machining of a workpiece, the created machining product is moved by means of the coordinate guidance of the punching machine to the edge of one of the support parts of the workpiece support. The platform of the loading and unloading device is arranged laterally next to the workpiece support of the punching machine in the vertical direction slightly below the workpiece support. With the processing product stored thereon, the workpiece support of the punching machine subsequently moves from a starting position via the platform of the loading and unloading device. Now, the gripper of the loading and unloading device is delivered in the horizontal direction until it can detect the edge of the stored from the workpiece support of the punching machine processing product. If the processing product is fixed to the gripper of the loading and unloading device, moves the workpiece support of the punching machine back to its original position. In this case, the relevant support part of the workpiece support is pulled out under the processing product and the processing product is placed under gravity on the underlying platform of the loading and unloading.
Das Entladen von Bearbeitungsprodukten an einer maschinellen Anordnung der eingangs genannten Art zu vereinfachen, ist Aufgabe der vorliegenden Erfindung.To simplify the unloading of machining products on a machine arrangement of the type mentioned, is the object of the present invention.
Erfindungsgemäß gelöst wird diese Aufgabe durch die maschinelle Anordnung gemäß Patentanspruch 1 und das Verfahren zum Handling eines Bearbeitungsprodukts gemäß Patentanspruch 16.This object is achieved according to the invention by the mechanical arrangement according to
Im Falle der Erfindung ist eine Werkstückauflage mit einem entladeseitigen Auflagenteil und einem weiteren Auflagenteil vorgesehen, wobei der entladeseitige Auflagenteil in vertikaler Richtung verstellt werden kann. Befinden sich die beiden Auflagenteile auf einem gemeinsamen Niveau, so fluchten sie miteinander und insbesondere ein zu bearbeitendes Werkstück kann mittels der Bewegungsvorrichtung der erfindungsgemäßen maschinellen Anordnung zu Bearbeitungszwecken über die beiden Auflagenteile bewegt werden. Sind als Bearbeitungsstation der maschinellen Anordnung eine Stanzstation und als Bewegungsvorrichtung eine Koordinatenführung vorgesehen, so wird das zu bearbeitende Werkstück, beispielsweise ein zu bearbeitendes Blech, mittels der Koordinatenführung gegenüber dem Stanzwerkzeug der Stanzstation auf bekannte Art und Weise mit Bewegungen in einer horizontalen Ebene zugestellt. An der Bewegungsvorrichtung ist das zu bearbeitende Werkstück ebenso wie das als Ergebnis der Werkstückbearbeitung erzeugte Bearbeitungsprodukt fixiert. Als Bearbeitungsprodukte einer schneidenden, insbesondere stanzenden Blechbearbeitung kommen Fertigteile oder Restgitter und auch Restgitter mit daran über Micro-Joints gehaltenen Fertigteilen infrage.In the case of the invention, a workpiece support is provided with a discharge-side support part and a further support part, wherein the discharge-side support part can be adjusted in the vertical direction. If the two support parts are at a common level, they are aligned with each other and in particular a workpiece to be machined can be moved by means of the moving device of the mechanical arrangement according to the invention for processing purposes on the two support parts. If a stamping station is provided as the machining station of the mechanical arrangement and a coordinate guide is provided as the movement device, then the workpiece to be machined, for example a metal sheet to be machined, is delivered in a known manner with movements in a horizontal plane by means of the coordinate guide relative to the punching tool of the stamping station. On the moving device, the workpiece to be machined is fixed as well as the machining product produced as a result of the workpiece machining. As processing products of a cutting, in particular punching sheet metal processing are finished parts or skeletons and skeletons with it held on micro-joints finished parts in question.
Nach Beendigung der Werkstückbearbeitung und vor Einleitung des Entladevorganges ist das Bearbeitungsprodukt auf dem weiteren Auflagenteil der Werkstückauflage gelagert. Der entladeseitige Auflagenteil der Werkstückauflage wird in vertikaler Richtung auf ein Entladeniveau abgesenkt. Befindet sich der entladeseitige Auflagenteil der Werkstückauflage auf dem Entladeniveau, so kann die Handlingvorrichtung seitlich neben dem weiteren Auflagenteil eine Entladeposition einnehmen. In der Entladeposition ist die Handlingvorrichtung in vertikaler Richtung derart angeordnet, dass eine an der Handlingvorrichtung für das Bearbeitungsprodukt vorgesehene Produktauflage gegenüber dem weiteren Auflagenteil der Werkstückauflage eine Position einnimmt, bei welcher das auf dem weiteren Auflagenteil gelagerte und an der Bewegungsvorrichtung festgelegte Bearbeitungsprodukt mittels der Bewegungsvorrichtung auf die Produktauflage der Handlingvorrichtung transferiert werden kann.After completion of the workpiece machining and before the initiation of the unloading process, the machining product is mounted on the further support part of the workpiece support. The discharge-side support part of the workpiece support is lowered in the vertical direction to a discharge level. If the discharge-side support part of the workpiece support is at the unloading level, then the handling device can assume an unloading position laterally next to the further support part. In the unloading position, the handling device is arranged in the vertical direction such that a product support provided on the handling device for the processing product assumes a position relative to the further support part of the workpiece support, wherein the processing product mounted on the further support part and fixed to the movement device by means of the movement device the product support of the handling device can be transferred.
Im Falle der Erfindung besteht somit die Möglichkeit, das nach der Werkstückbearbeitung an der Bewegungsvorrichtung der maschinellen Anordnung festgelegte Bearbeitungsprodukt mittels der Bewegungsvorrichtung ohne Umspannen von dem weiteren Auflagenteil der Werkstückauflage auf die Handlingvorrichtung zu bewegen. Die Bewegungsvorrichtung kann folglich unmittelbar mit dem Entladen der Werkstückauflage der maschinellen Anordnung die Handlingvorrichtung mit dem Bearbeitungsprodukt beladen. Vorzugsweise bildet die Produktauflage die obere Begrenzung der Handlingvorrichtung.In the case of the invention, it is thus possible to move the machining product fixed to the moving device of the machine arrangement after workpiece machining by means of the movement device without re-clamping the further support part of the workpiece support onto the handling device. The movement device can therefore immediately with the unloading the workpiece support of the mechanical arrangement, the handling device loaded with the processed product. Preferably, the product support forms the upper limit of the handling device.
Besondere Ausführungsarten der in den unabhängigen Patentansprüchen 1 und 16 beschriebenen Erfindung ergeben sich aus den abhängigen Patentansprüchen 2 bis 15 und 17.Particular embodiments of the invention described in the
Zur Höhenverstellung des entladeseitigen Auflagenteils der Werkstückauflage bieten sich erfindungsgemäß unterschiedliche Möglichkeiten. Denkbar ist beispielsweise ein ausschließlich zu diesem Zweck vorgesehener motorischer Stellantrieb.To adjust the height of the discharge-side support part of the workpiece support, different possibilities according to the invention. It is conceivable, for example, an exclusively provided for this purpose motor actuator.
Erfindungsgemäß bevorzugt wird ausweislich Patentanspruch 2 die Verwendung der Handlingvorrichtung zum Absenken des entladeseitigen Auflagenteils der Werkstückauflage auf das Entladeniveau. Vorzugsweise wird dabei mittels der Handlingvorrichtung Druck auf die Oberseite des entladeseitigen Auflagenteils ausgeübt. Unter der Wirkung dieses Drucks senkt sich der entladeseitige Auflagenteil gegenüber dem weiteren Auflagenteil vorzugsweise ausgehend von dem gemeinsamen Niveau auf das Entladeniveau ab. Aufgrund der erfindungsgemäßen Mehrfachnutzung der Handlingvorrichtung lässt sich die Höhenverstellung des entladeseitigen Auflagenteils mit einem verhältnismäßig geringen konstruktiven Aufwand realisieren.According to the invention, the use of the handling device for lowering the discharge-side support part of the workpiece support to the unloading level is preferred. Preferably, pressure is exerted on the top side of the discharge-side support part by means of the handling device. Under the effect of this pressure, the discharge-side support part preferably lowers from the common level to the discharge level with respect to the further support part. Due to the multiple use of the handling device according to the invention, the height adjustment of the discharge-side support member can be realized with a relatively small design effort.
Aus entsprechenden Gründen ist im Falle der Erfindungsbauart gemäß Patentanspruch 3 ein Absenken des entladeseitigen Auflagenteils der Werkstückauflage gegen die Wirkung einer Rückstellkraft vorgesehen. Die Rückstellkraft bewirkt nach dem Entladen der Werkstückauflage ein selbsttätiges Anheben des entladeseitigen Auflagenteils von dem Entladeniveau auf das Ausgangsniveau, insbesondere auf das gemeinsame Niveau, auf welchem die beiden Auflagenteile der Werkstückauflage der erfindungsgemäßen maschinellen Anordnung miteinander fluchten.For corresponding reasons, in the case of Erfindungsbauart according to
Im Interesse einer hohen Funktionssicherheit der erfindungsgemäßen maschinellen Anordnung und des erfindungsgemäßen Verfahrens ist ausweislich Patentanspruch 4 in weiterer bevorzugter Ausgestaltung der Erfindung eine Entladehilfe vorgesehen, mittels derer das auf die Produktauflage der Handlingvorrichtung bewegte Bearbeitungsprodukt von der Bewegungsvorrichtung weg bewegbar ist. Auf diese Art und Weise wird für eine funktionssichere Trennung des zunächst noch an der Bewegungsvorrichtung festgelegten Bearbeitungsprodukts von der Bewegungsvorrichtung gesorgt.In the interest of a high reliability of the machine assembly according to the invention and the method according to the invention is disclosed in
Eine kompakte Bauweise der Gesamtanordnung ergibt sich dann, wenn die Entladehilfe an der Handlingvorrichtung vorgesehen ist (Patentanspruch 5).A compact design of the overall arrangement results when the Entladehilfe is provided on the handling device (claim 5).
Eine Fixierungsvorrichtung, wie sie ausweislich Patentanspruch 6 in Weiterbildung der Erfindung vorgesehen ist, dient dazu, das auf die Handlingvorrichtung transferierte Bearbeitungsprodukt gegen eine unerwünschte Verlagerung, insbesondere gegen Herunterfallen zu sichern. Die Sicherungsfunktion der Fixierungsvorrichtung ist insbesondere deshalb von Bedeutung, weil das Bearbeitungsprodukt mittels der Handlingvorrichtung aus dem Nahbereich des entladeseitigen Auflagenteils der Werkstückauflage abgeführt werden muss, ehe der entladeseitige Auflagenteil der Werkstückauflage wieder auf sein Ausgangsniveau angehoben werden kann. Als Fixierungsvorrichtung in Frage kommt beispielsweise eine Klemmvorrichtung. Die Klemmvorrichtung kann als Kniehebelmechanismus ausgeführt sein.A fixing device, as provided by
Im Interesse einer kompakten Bauweise der Gesamtanordnung bildet im Falle einer bevorzugten Erfindungsbauart die Entladehilfe, mittels derer das Bearbeitungsprodukt von der Bewegungsvorrichtung getrennt wird, gleichzeitig die Fixierungsvorrichtung aus.In the interests of a compact construction of the overall arrangement, in the case of a preferred embodiment of the invention, the unloading aid, by means of which the processing product is separated from the moving device, simultaneously forms the fixing device.
Gemäß Patentanspruch 7 ist in weiterer Ausgestaltung der Erfindung vorgesehen, dass das von der Handlingvorrichtung übernommene Bearbeitungsprodukt gemeinsam mit der Handlingvorrichtung in eine Umschlag-position bewegt und ausgehend von der Umschlagposition mittels einer Umschlagvorrichtung zu einer Produktablage, beispielsweise auf eine entsprechende Palette, transferiert wird.According to
Der Einfachheit halber ist die Umschlagvorrichtung im Falle der Erfindungsbauart nach Patentanspruch 8 als Abstreifvorrichtung ausgebildet. Mittels der Abstreifvorrichtung wird das auf der Produktauflage der Handlingvorrichtung abgelegte Bearbeitungsprodukt auf die Produktablage, gegebenenfalls auf eine Produktpalette, abgestreift. Zur Erzeugung einer Abstreifbewegung führen die mit dem Bearbeitungsprodukt beladenen Handlingvorrichtung einerseits und die Abstreifvorrichtung andererseits eine vorzugsweise horizontale Relativbewegung aus.For simplicity, the transhipment device is designed in the case of Erfindungsbauart according to
Gemäß Patentanspruch 9 ist die Handlingvorrichtung im Falle einer weiteren bevorzugten Erfindungsbauart in der Umschlagposition auf einem niedrigeren Niveau angeordnet als in der Entladeposition. Die Produktablage, die mittels der in die Umschlagposition bewegten Handlingvorrichtung zusammenwirkt, kann demnach in einem Bereich der erfindungsgemäßen maschinellen Anordnung vorgesehen werden, in welchem sie die in der Entladeposition befindliche Handlingvorrichtung nicht behindert.According to
In weiterer bevorzugter Ausgestaltung der Erfindung wird die Handlingvorrichtung der erfindungsgemäßen maschinellen Anordnung nicht nur zum Entladen sondern auch zum Beladen der Werkstückauflage verwendet (Patentansprüche 10, 17). Der entladeseitige Auflagenteil der Werkstückauflage bildet gleichzeitig einen beladeseitigen Auflagenteil. Ein zu bearbeitendes Werkstück, welches der Werkstückauflage der maschinellen Anordnung zuzuführen ist, wird an der Handlingvorrichtung mittels einer Haltevorrichtung derart fixiert, dass das zu bearbeitende Werkstück an der von der Produktauflage abliegenden Unterseite der Handlingvorrichtung angeordnet ist. Zum Beladen der Werkstückauflage, im Einzelnen des be- und entladeseitigen Auflagenteils, wird die Handlingvorrichtung in eine Beladeposition bewegt, in welcher die Handlingvorrichtung gemeinsam mit dem an die Werkstückauflage zu übergebenden Werkstück über dem be- und entladeseitigen Auflagenteil liegt. Von der über dem be- und entladeseitigen Auflagenteil angeordneten Handlingvorrichtung wird das Werkstück an den be- und entladeseitigen Auflagenteil übergeben.In a further preferred embodiment of the invention, the handling device of the machine arrangement according to the invention not only for unloading but also for loading the workpiece support is used (
Die an der Unterseite der Handlingvorrichtung vollzogene Übergabe eines zu bearbeitenden Werkstücks von der Handlingvorrichtung an den be- und entladeseitigen Auflagenteil kann gleichzeitig erfolgen mit dem an der gegenüberliegenden Seite der Handlingvorrichtung mittels der Bewegungsvorrichtung durchgeführten Transfer eines Bearbeitungsprodukts von dem weiteren Auflagenteil auf die Produktauflage der Handlingvorrichtung. In diesem Fall ist der be- und entladeseitige Auflagenteil der Werkstückauflage zum Zeitpunkt des Beladens mit dem zu bearbeitenden Werkstück auf das Entladeniveau abgesenkt.The handover of a workpiece to be processed from the handling device to the loading and unloading side part carried out on the underside of the handling device can take place simultaneously with the transfer of a processing product from the further support part to the product support of the handling device on the opposite side of the handling device by means of the movement device. In this case, the loading and unloading side support part of the workpiece support at the time of loading with the workpiece to be machined is lowered to the unloading level.
In bevorzugter Ausgestaltung der Erfindung erfolgt die Übergabe des zu bearbeitenden Werkstücks an die Werkstückauflage erst nach deren Entladen und somit nachdem das von der Werkstückauflage abzuführende Bearbeitungsprodukt auf die Produktauflage der Handlingvorrichtung bewegt worden ist. Nach dem Transfer des Bearbeitungsprodukts auf die Handlingvorrichtung wird diese zunächst angehoben, wobei der zum Zeitpunkt des Entladens der Werkstückauflage auf das Entladeniveau abgesenkte be- und entladeseitige Auflagenteil vorzugsweise zeitgleich mit der Hubbewegung der Handlingvorrichtung auf das gemeinsame Niveau angehoben wird, auf welchem der be- und entladeseitige Auflagenteil mit dem weiteren Auflagenteil der Werkstückauflage fluchtet.In a preferred embodiment of the invention, the transfer of the workpiece to be machined to the workpiece support takes place only after it has been unloaded and thus after the machining product to be removed from the workpiece support has been moved onto the product support of the handling device. After the transfer of the processing product to the handling device, this is first raised, wherein at the time of unloading the workpiece support lowered to the discharge level loading and unloading side support member is preferably raised simultaneously with the lifting movement of the handling device to the common level, on which the loading and unloading side support part with the other support part of the workpiece support is aligned.
Diese Vorgehensweise empfiehlt sich insbesondere in Fällen, in denen als Bewegungsvorrichtung für das Werkstück und das Bearbeitungsprodukt eine Bewegungsvorrichtung vorgesehen ist, die sich, wie beispielsweise eine herkömmliche Koordinatenführung, auf einem dem gemeinsamen Niveau der Auflagenteile der Werkstückauflage zugeordneten Niveau befindet. Ist die Anordnung der Bewegungsvorrichtung auf das gemeinsame Niveau des be- und entladeseitigen Auflagenteils und des weiteren Auflagenteils der Werkstückauflage abgestimmt, so liegt das von der Handlingvorrichtung an den be- und entladeseitigen Auflagenteil zu übergebende Werkstück beim Entladen der Werkstückauflage unterhalb der Bewegungsvorrichtung.This procedure is particularly recommended in cases in which a movement device is provided as a movement device for the workpiece and the machining product, which is located, for example, a conventional coordinate guide, on a common level of the support parts of the workpiece support level. If the arrangement of the movement device is adapted to the common level of the loading and unloading side support part and the further support part of the workpiece support, the workpiece to be transferred from the handling device to the loading and unloading side support part lies below the movement device during unloading of the workpiece support.
Wird im Falle einer derartigen Bauart der erfindungsgemäßen maschinellen Anordnung die Handlingvorrichtung nach dem Entladen der Werkstückauflage mit dem an der Handlingvorrichtung lösbar gehaltenen Werkstück auf ein entsprechendes Niveau in eine Beladeposition angehoben, so kann das zu bearbeitende Werkstück von der Handlingvorrichtung unmittelbar, das heißt ohne vorheriges Lösen von der Handlingvorrichtung und ohne vorherige Ablage auf dem be- und entladeseitigen Auflagenteil, an die Bewegungsvorrichtung übergeben werden. Von der Handlingvorrichtung gelöst wird das zu bearbeitende Werkstück erst, nachdem es an der Bewegungsvorrichtung festgelegt worden ist. Spätestens zu diesem Zeitpunkt sollte der be- und entladeseitige Auflagenteil der Werkstückauflage auf das gemeinsame Niveau angehoben sein. Unmittelbar nach dem Lösen von der Handlingvorrichtung kann das Werkstück dann mittels der Bewegungsvorrichtung in der für die Bearbeitung erforderlichen Weise über die Werkstückauflage bewegt werden.If, in the case of such a design of the mechanical arrangement according to the invention, the handling device is lifted to a corresponding level in a loading position after unloading the workpiece support with the workpiece detachably held on the handling device, then the workpiece to be machined can be handled directly by the handling device, ie without prior release be transferred from the handling device and without prior storage on the loading and unloading side support part to the moving device. Detached from the handling device, the workpiece to be machined only after it has been fixed to the moving device. At the latest at this time, the loading and unloading side support part of the workpiece support should be raised to the common level. Immediately after releasing from the handling device, the workpiece can then be moved over the workpiece support in the manner required for machining by means of the movement device.
Erfindungsgemäß bevorzugt wird eine Anordnung der Handlingvorrichtung in der Beladeposition derart, dass das an der Handlingvorrichtung festgelegte und an der Unterseite der Handlingvorrichtung angeordnete Werkstück mit einer horizontalen Transferbewegung zu der Bewegungsvorrichtung hin bewegbar ist (Patentanspruch 11). Auf diese Art und Weise ist eine funktionssichere und mit einer kinematisch einfachen Werkstückbewegung realisierbare Übergabe des zu bearbeitende Werkstücks von der Handlingvorrichtung an die Bewegungsvorrichtung gewährleistet.According to the invention, an arrangement of the handling device in the loading position is such that the workpiece fixed to the handling device and arranged on the underside of the handling device is movable toward the movement device with a horizontal transfer movement (claim 11). In this way, a functionally reliable and with a kinematically simple workpiece movement feasible transfer of the workpiece to be machined from the handling device is guaranteed to the movement device.
Der Transfer des zu bearbeitenden Werkstücks zu der Bewegungsvorrichtung kann ausschließlich durch eine entsprechende Bewegung der Handlingvorrichtung erfolgen. Lässt in diesem Fall die Werkstück-Haltevorrich-tung der Handlingvorrichtung Bewegungen des an der Handlingvorrichtung gehaltenen Werkstücks in der Werkstückebene zu (Patentanspruch 12), so kann das an der Handlingvorrichtung fixierte Werkstück gegenüber der Bewegungsvorrichtung in der Werkstückebene derart ausgerichtet werden, dass eine sichere Übernahme des Werkstücks durch die Bewegungsvorrichtung gewährleistet ist.The transfer of the workpiece to be machined to the movement device can be done exclusively by a corresponding movement of the handling device. In this case, if the workpiece holding device of the handling device permits movements of the workpiece held on the handling device in the workpiece plane (claim 12), the workpiece fixed to the handling device can be aligned relative to the movement device in the workpiece plane in such a way that a secure transfer takes place of the workpiece is ensured by the movement device.
In Weiterbildung der Erfindung ist ausweislich Patentanspruch 13 eine zum aktiven Werkstücktransfer dienende Beladehilfe vorgesehen, wobei es erfindungsgemäß denkbar ist, dass die Handlingvorrichtung und die Beladehilfe jeweils einen Teil des Werkstücktransfers zu der Bewegungsvorrichtung übernehmen. Im Interesse einer kompakten Bauweise der Gesamtanordnung kann die Beladehilfe an der Handlingvorrichtung vorgesehen sein.According to a further development of the invention, a loading aid serving for active workpiece transfer is provided, it being conceivable in accordance with the invention that the handling device and the loading aid each take over part of the workpiece transfer to the movement device. In the interest of a compact design of the overall arrangement, the loading aid may be provided on the handling device.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist die Handlingvorrichtung in der Lage, ein zu bearbeitendes Werkstück, welches der Werkstückauflage zugeführt werden soll, an einer Werkstückablage aufzunehmen. Zu diesem Zweck ist die Handlingvorrichtung in eine Aufnahmeposition an der Werkstückablage bewegbar. Mittels der Werkstück-Haltevor-richtung der Handlingvorrichtung wird das von der Werkstückablage aufgenommene Werkstück an der Handlingvorrichtung mit Anordnung an deren Unterseite lösbar festgelegt (Patentanspruch 14).In a further advantageous embodiment of the invention, the handling device is able to record a workpiece to be machined, which is to be supplied to the workpiece support on a workpiece tray. For this purpose, the handling device is movable in a receiving position on the workpiece tray. By means of the workpiece holding device of the handling device, the workpiece received by the workpiece deposit is releasably secured to the handling device with an arrangement on its underside (claim 14).
Im Falle der Erfindungsbauart gemäß Patentanspruch 15 kann die Handlingvorrichtung sowohl ein auf der Produktauflage der Handlingvorrichtung abgelegtes Bearbeitungsprodukt an eine Produktablage für Bearbeitungsprodukte übergeben als auch ein zu bearbeitendes Werkstück von einer Werkstückablage für zu bearbeitende Werkstücke aufnehmen. Zum Transfer eines Bearbeitungsprodukts an die Produktablage ist die Handlingvorrichtung in die Umschlagposition gemäß Patentanspruch 7, zur Aufnahme eines zu bearbeitenden Werkstücks von der Werkstückablage in die Aufnahmeposition gemäß Patentanspruch 14 bewegbar. Durch eine verhältnismäße kleine Aufstellfläche zeichnet sich die erfindungsgemäße maschinellen Anordnung dann aus, wenn - wie ausweislich Patentanspruch 15 vorgesehen - die Umschlagposition der Handlingvorrichtung oberhalb der Aufnahmeposition der Handlingvorrichtung angeordnet ist.In the case of Erfindungsbauart according to

Ausgehend von den Verhältnissen gemäß
Sobald die laufende Blechbearbeitung an der Stanzmaschine 2 beendet ist, wird ein als Ergebnis der Blechbearbeitung erzeugtes und als Bearbeitungsprodukt vorliegendes Restgitter 22 mittels der Koordinatenführung 13 derart auf der Werkstückauflage 3 positioniert, dass es ausschließlich auf dem weiteren Auflagenteil 6 liegt. Damit ergibt sich der in
Befindet sich das Restgitter 22 vollständig auf dem weiteren Auflagenteil 6, so wird der Saugerrahmen 9 gemeinsam mit dem daran festgelegten Rohblech 12 durch eine entsprechende Bewegung des Führungsrahmens 8 aus der Position gemäß
Nimmt der Saugerrahmen 9 die Entladeposition über dem auf das Entladeniveau abgesenkten be- und entladeseitigen Auflagenteil 5 ein, so wird das zunächst auf dem weiteren Auflagenteil 6 befindliche Restgitter 22 mittels der Koordinatenführung 13 auf die Produktauflage 23 des Saugerrahmens 9 bewegt (
Sobald das Restgitter 22 vollständig auf die Produktauflage 23 des in der Entladeposition befindlichen Saugerrahmens 9 transferiert ist (
Ausgehend von diesen Verhältnissen werden die Spannpratzen 24 der Koordinatenführung 13 geöffnet und die mittels der Spannpratzen 24 bewirkte Klemmung des Restgitters 22 wird aufgehoben. Nun wird ein in den Darstellungen verdeckt liegender pneumatischer Kolben-Zylinder-Antrieb der Kniehebelanordnung 19 betätigt und der Spannarm 25 schwenkt ausgehend von seiner Stellung gemäß
Nun wird der Saugerrahmen 9 mittels des Führungsrahmens 8 aus der Entladeposition gemäß den
Befindet sich der Saugerrahmen 9 in der Beladeposition, so liegt das an der Unterseite des Saugerrahmens 9 festgelegte Rohblech 12 auf Höhe der nach wie vor geöffneten Spannpratzen 24 der Koordinatenführung 13. Dabei ist das Rohblech 12 in der Blechebene schwimmend an dem Saugerrahmen 9 gelagert.If the
Mit einer horizontalen Transferbewegung kann nun das Rohblech 22 an die Koordinatenführung 13 übergeben werden.With a horizontal transfer movement, the
In dem dargestellten Beispielsfall wird die horizontale Transferbewegung des Rohblechs 12 mittels des Saugerrahmens 9 ausgeführt. Der Saugerrahmen 9 verfährt mit dem daran festgelegten Rohblech 12 horizontal in Richtung auf die Koordinatenführung 13. Das Rohblech 12 läuft dabei in die geöffneten Spannpratzen 24 der Koordinatenführung 13 ein, bis es an Tiefenanschlägen der Spannpratzen 24 zur Anlage kommt. Damit endet die horizontale Zustellbewegung des Saugerrahmens 9. Die Spannpratzen 24 werden geschlossen und das Rohblech 12 ist an der Koordinatenführung 13 festgelegt.In the illustrated example case, the horizontal transfer movement of the
Ist das an dem Saugerrahmen 9 festgelegte Rohblech 12 mit seiner zu der Koordinatenführung 13 hin weisenden Kante nicht exakt parallel zu der Querschiene 16 und somit nicht exakt parallel zu der längs der Querschiene 16 verlaufenden gedachten Verbindungslinie der an den Spannpratzen 24 vorgesehenen Tiefenanschläge ausgerichtet, so schlägt das Rohblech 12 bei der mittels des Saugerrahmens 9 in Richtung auf die Koordinatenführung 13 ausgeführten Bewegung zunächst lediglich an dem Tiefenanschlag einer der Spannpratzen 24 an. Da nun aber das Rohblech 12 mittels des Saugerfelds 17 in der Blechebene schwimmend an dem Saugerrahmen 9 gelagert ist, kann der Saugerrahmen 9 nach dem Anschlagen des Rohblechs 12 an dem Tiefenanschlag einer der Spannpratzen 24 seine Bewegung in Richtung auf die Koordinatenführung 13 fortsetzen, bis das Rohblech 12 auch auf die Tiefenanschläge der weiteren Spannpratzen 24 aufgelaufen ist und das Rohblech 12 folglich mit seiner der Koordinatenführung 13 zugewandten Kante exakt parallel zu der Querschiene 16 verläuft und beim Schließen der Spannpratzen 24 sicher an der Koordinatenführung 13 festgelegt wird.If the
Die schwimmende Lagerung des Rohblechs 12 an dem Saugerrahmen 9 kann beispielsweise mit Hilfe von Vakuumsaugern 18 realisiert werden, die als sogenannte Drehpunktsauger ausgebildet und als solche in der Blechebene des Rohblechs 12 flexibel sind. Umfasst das Saugerfeld 17 neben derartigen Drehpunktsaugern auch in der Blechebene starre Vakuumsauger 18, so wird durch entsprechende Ansteuerung des Saugerfeldes 17 dafür gesorgt, dass das Rohblech 12 bei seiner Übergabe an die Spannpratzen 24 der Koordinatenführung 13 nur noch mittels der Drehpunktsauger an dem Saugerrahmen 9 gehalten wird.The floating support of the
