Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 3 gelöst.This task comes with the characteristic Characteristics of claim 3 solved.

Im folgenden werden Ausführungsbeispiele der Erfindung anhand der Figuren näher erläutert. Dabei zeigt

  • Figur 1 grob schematisch eine Draufsicht auf eine Vorschubvorrichtung;
  • Figur 2 eine Draufsicht gemäss Figur 1 mit den Blechen in der Übergabeposition, und
  • Figur 3 eine ebenfalls nur schematische Seitenansicht der Vorschubvorrichtung.
    • In the following, embodiments of the invention will be explained in more detail with reference to FIGS. It shows
  • Figure 1 roughly schematically a plan view of a feed device;
  • Figure 2 is a plan view according to Figure 1 with the sheets in the transfer position, and
  • Figure 3 is also a schematic side view of the feed device.

    • Die Figuren 1 bis 3 zeigen schematisch in Draufsicht und Seitenansicht die Vorschubvorrichtung 1, welche vor einer Stanzeinrichtung 2 angeordnet ist, die ein Werkzeug 4 aufweist, welches aus einer Blechtafel 3 Gegenstände 5 ausstanzt (nur ein Stanzloch von vielen ist beispielhaft gezeigt), so dass nach der Stanzung diese Gegenstände vereinzelt vorliegen und von der Blechtafel 3 nur noch ein Restgitter besteht. Die Art und Weise der Stanzung wird hier, da bekannt, nicht näher erläutert. Es kann auf bekannte Weise eine Stanzung mit einem zweireihigen Werkzeug stattfinden, so dass das jeweilige Blech nur in Vorschubrichtung A durch die Stanzeinrichtung 2 geschoben werden muss, oder es kann auf ebenfalls bekannte Weise eine Stanzung mit einem einreihigen Werkzeug stattfinden, wobei dann das Blech noch in einer Richtung senkrecht zur Richtung A hin und her verschoben werden muss, was bekannt ist. Nachfolgend wird die Vorschubeinrichtung 1 so erläutert, dass sie nur den Vorschub in Richtung A durchführt. Sollte auch eine Hin- und Herbewegung senkrecht dazu erforderlich sein, so kann diese durch weitere Betätigungselemente ohne weiteres ausgeführt werden, was indes nachfolgend nicht weiter erläutert wird.FIGS. 1 to 3 show schematically in FIG Top view and side view of the feed device 1, which is arranged in front of a punching device 2, the a tool 4, which consists of a metal sheet. 3 Punching out items 5 (only one punched hole is out of many shown by way of example), so that after punching this Items are present in isolation and from the sheet metal 3 only a skeleton remains. The way of Punching is here, as known, not further explained. It can in a known manner a punching with a double row Tool take place, so that the respective sheet metal only in the feed direction A by the punching device. 2 has to be pushed, or it may also be known Do a punching with a single-row tool take place, in which case the sheet still in one direction be moved back and forth perpendicular to the direction A. must know what is known. Subsequently, the feed device 1 explained that they only feed in Direction A performs. Should also have a back and forth movement may be required perpendicular to it, this may performed by further actuators readily which, however, are not explained further below becomes.

    Die Vorschubeinrichtung 1 weist bevorzugterweise ein Trag- und Führungsglied 6 auf, an welchem Schlitten 7 und 12 in Vorschubrichtung und in Gegenrichtung beweglich angeordnet sind. Die Schlitten werden durch einen nicht näher dargestellten Antrieb 17 in Vorschubrichtung und in Gegenrichtung bewegt, z.B. durch Zahnriemen oder Ketten, die um Rollen 18, 19 im Tragglied 6 umlaufen, und an welchen die Schlitten befestigt sind. Natürlich sind auch beliebige andere Antriebe der Schlitten mit Spindeln oder mit Linearantrieben dem Fachmann geläufig und ohne weiteres realisierbar. Der Antrieb für die Schlitten wird durch eine Steuerung 25 gesteuert, welche auch Signale von Lagesensoren 26 für das Blech empfangen kann und welche weiter mit der Steuerung 27 für die Stanzeinrichtung 2 in Verbindung steht, um den Vorschub und das Stanzen zu synchronisieren. Die Steuerung 25 kann die Lage der Schlitten ebenfalls durch Sensoren oder durch Geber am Antrieb 17 erkennen.The feed device 1 preferably has a support and guide member 6, on which Carriage 7 and 12 in the feed direction and in the opposite direction are movably arranged. The sled will be by a drive 17, not shown in the feed direction and moved in the opposite direction, e.g. by Timing belts or chains around rollers 18, 19 in the support member 6 circulate, and to which the carriages are attached. Of course, any other drives of the slide with spindles or with linear drives the expert common and readily feasible. The drive for the carriages are controlled by a controller 25, which also signals from position sensors 26 for the sheet can receive and which continue with the controller 27 for the punching device 2 is in communication with the feed and to synchronize the punching. The control 25, the location of the carriage can also be through sensors or by encoder on the drive 17 recognize.

    Die Vorschubvorrichtung 1 arbeitet auf an sich bekannte Weise derart, dass die erste Vorschubvorrichtung 7-10 ein von einem nicht gezeigten Stapel abgestapeltes Blech 3, welches auf dem Vorschubtisch 20 abgelegt wird, ergreift und in Richtung auf die Stanzeinrichtung vorschiebt. Eine zweite Vorschubeinrichtung 12-15 ist gleichzeitig damit beschäftigt, ein vorangehendes Blech durch die Stanzeinrichtung 2 zu führen, wobei dies auf bekannte Weise in Synchronisation mit der Stanzbewegung erfolgt. In einer Übergabestellung, welche in Figur 2 dargestellt ist, wird ein von der ersten Vorschubeinrichtung 7-10 in die Stanzeinrichtung 2 eingeschobenes Blech an die zweite Vorschubeinrichtung 12-15 übergeben. Diese Übergabe kann z.B. und wie in Figur 2 gezeigt, bei der ersten Stanzung erfolgen, kann aber natürlich auch erst später nach einigen Stanzvorgängen erfolgen. Die Übergabe erfolgt dadurch, dass die Greifmittel 10 der ersten Vorschubeinrichtung und die Greifmittel 15 der zweiten Vorschubeinrichtung auf die gleiche Vorschubhöhe gelangen, so dass die Greifmittel 15 das Blech greifen können, das bisher von den Greifmitteln 10 gehalten wurde, wobei diese das Blech freigeben.The feed device 1 operates on known manner such that the first feed device 7-10 a stacked from a stack, not shown Sheet 3, which is placed on the feed table 20 becomes, and takes in the direction of the punching device advances. A second feed device 12-15 is at the same time busy, a previous one Lead sheet through the punching device 2, this in a known manner in synchronization with the punching movement he follows. In a transfer position, which in FIG 2, one of the first feed device is shown 7-10 inserted into the punching device 2 Sheet transferred to the second feed device 12-15. This handover may e.g. and as shown in FIG of the first punching, but of course, too take place later after a few punching operations. The Transfer takes place in that the gripping means 10 of the first Feed device and the gripping means 15 of the second Feed device reach the same feed height, so that the gripping means 15 can grip the sheet, which was previously held by the gripping means 10, these release the sheet.

    Die Greifzangen 10 bzw. 15 sind an sich bekannte zangenartige Bauelemente, welche zum Öffnen und Schliessen betätigt werden können, um das jeweilige Blech loszulassen bzw. zu greifen. Die Greifelemente 10 und 15 weisen in Förderrichtung gesehen nach hinten weisende Fortsätze 9 bzw. 10 auf, welche die Greifzangen 10, 15 mit Führungs- und Betätigungselementen 8 bzw. 13 auf den Schlitten 7 bzw. 12 verbinden. Die Führungs- und Betätigungselemente 8, 13 sind auf den Schlitten 7 bzw. 12 verschiebbar befestigt, so dass deren Lage entlang des jeweiligen Schlittens eingestellt werden kann. Über die Fortsätze 9 bzw. 14 kann auch die Betätigung der Zangenöffnung und -schliessung erfolgen. Die Führungselemente 8 bzw. 13 sind auf den Schlitten quer zur Vorschubrichtung A einstellbar, wobei deren gegenseitige Distanz in Figur 2 mit B bzw. B1 eingezeichnet ist. Die Verstellung entlang des Schlittens 7 bzw. 12 erfolgt zur Anpassung an das jeweilige Blechformat. Wie besonders gut in Figur 2 ersichtlich, ist die erste Vorschubeinrichtung 7-10 so ausgestaltet, dass in der Übergabeposition nur deren Greifmittel 9, 10 durch die zweite Vorschubeinrichtung 12-15 hindurchgreifen, während die Führungs- und Betätigungsmittel 8 und der Schlitten 7 der ersten Vorschubeinrichtung in Vorschubrichtung gesehen hinter der zweiten Vorschubeinrichtung 12-15 verbleibt. Dies erlaubt eine einfache Einstellung des Abstandes B der Greifmittel 9, 10 der ersten Vorschubeinrichtung unabhängig von der zweiten Vorschubeinrichtung und auch das einfache Einstellen des Abstandes B1 zwischen den Greifmitteln 15 der zweiten Vorschubeinrichtung. Die Einstellung dieser Abstände B, B1 ist weiter dadurch vereinfacht, dass beide Vorschubeinrichtungen oberhalb des Tisches 20 bzw. der Vorschubebene angeordnet sind. Dies ergibt eine gute Zugänglichkeit zur Einstellung bzw. Umrüstung und ferner eine Unabhängigkeit von Durchbrüchen im Tisch 20, wie sie bei von unten her an das Blech angreifenden Vorschubeinrichtungen benötigt werden. Das Trageglied 6 kann dabei durch nicht gezeigte Befestigungsmittel oberhalb desselben oder seitlich desselben am Maschinengestell befestigt sein.The gripper tongs 10 and 15 are known per se pincer-like components which open and Close can be pressed to the respective sheet metal let go or grab. The gripping elements 10 and 15 have in the conveying direction facing backwards Fortsuits 9 and 10, which the gripper tongs 10, 15th with management and actuation elements 8 and 13 on the Connect carriage 7 or 12 respectively. The guiding and actuating elements 8, 13 are slidable on the carriage 7 and 12 respectively attached so that their location along the respective Sled can be adjusted. About the Fortsätze 9 and 14 can also be the operation of the forceps opening and closure. The guide elements 8 and 13 are on the carriage transversely to the feed direction A adjustable, with their mutual distance is shown in Figure 2 with B and B1. The Adjustment along the carriage 7 and 12 takes place for Adaptation to the respective sheet metal format. How very good seen in Figure 2, the first feed device 7-10 designed so that in the transfer position only the gripping means 9, 10 through the second feed device 12-15 pass through while the guiding and actuating means 8 and the carriage 7 of the first feed device seen in the feed direction behind the second Feed device 12-15 remains. This allows one easy adjustment of the distance B of the gripping means 9, 10 of the first feed device independent of the second feed device and also easy setting the distance B1 between the gripping means 15 of the second feed device. The setting of these distances B, B1 is further simplified by the fact that both Feed devices above the table 20 and the Feed level are arranged. This gives good accessibility for adjustment or conversion and further an independence from breakthroughs in the table 20, like her at from below to the sheet attacking feeders needed. The support member 6 can by fastening means not shown above the same or laterally attached to the machine frame be.
