Abstract

There are two parallel transporting rails (2) which can be moved horizontally and vertically by motors (12, 13). Each rail is linked to a coupling rod (14) for a horizontal motion. Traverses (7) are each in working engagement with at least one rail by means of at least one of the coupling rods. The traverses can be moved by an auxiliary transverse drive (9). This is driven synchronously with the drive motors for the horizontal movement of the rails towards each other. These drive motors are in a lock casing in the press. The transverse drive may have a torque transmission device (11) to move the traverses.

Description

Die Erfindung betrifft eine Vorrichtung zum Transfer von Werkstücken durch eine Folge von Bearbeitungsstationen nach der im Oberbegriff des Anspruchs 1 näher definierten Art.The invention relates to a device for transferring workpieces through a sequence of processing stations according to the kind defined in the preamble of claim 1.

Derartige Transfervorrichtungen werden in Pressen, Stufenpressen, Pressenstraßen, aber auch in Simulatoren zum Umsetzen von Werkstücken, im letztgenannten Anwendungsfall zum Einrichten einer Presse, verwendet.Such transfer devices are used in presses, step presses, press lines, but also in simulators for moving workpieces, in the latter application for setting up a press.

Hierbei ist eine separate Steuerung der Transportschienen in zwei bzw. drei Achsen erforderlich.This requires separate control of the transport rails in two or three axes.

Aus der Praxis ist eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 bekannt, bei welcher der Bewegungsantrieb der Transportschienen in ihrer Längsrichtung durch zumindest einen Motor erfolgt, der direkt, bei Verwendung eines Getriebes indirekt, auf ein Zahnrad, bei Verwendung eines Zahnriemens auf ein Umlenkrad, wirkt, wobei das Zahnrad mit einer sich in Längsrichtung der Transportschiene erstreckenden Zahnstange, das Umlenkrad mit einem sich in Längsrichtung der Transportschiene erstreckenden Zahnriemen zusammenwirkt, wobei an der Zahnstange bzw. an dem Zahnriemen in einem den Transportschienen fernen Bereich ein Abgriffspunkt gebildet ist, in dem eine Kuppelstange mit einem Endteil angelenkt ist, wobei der andere Endteil an die Transportschiene angelenkt ist.From practice, a device according to the preamble of claim 1 is known, in which the movement of the transport rails in their longitudinal direction is effected by at least one motor, which, directly when using a gear, indirectly on a gearwheel, when using a toothed belt on a deflection wheel, acts, the gearwheel cooperating with a toothed rack extending in the longitudinal direction of the transport rail, the deflection wheel cooperating with a toothed belt extending in the longitudinal direction of the transport rail, wherein a tap point is formed on the toothed rack or on the toothed belt in a region remote from the transport rails, in which a coupling rod is articulated with one end part, the other end part being articulated on the transport rail.

Nachteilig an der in der genannten Druckschrift offenbarten Vorrichtung ist jedoch, daß die unterschiedlichen Bewegungen der Transportschienen mechanisch gekoppelt sind, was eine relativ aufwendige Montage der gesamten Vorrichtung und verhältnismäßig viele bewegte Massen zur Folge hat.A disadvantage of the device disclosed in the cited publication, however, is that the different movements of the transport rails are mechanically coupled, which results in a relatively complex assembly of the entire device and a relatively large number of moving masses.

Bei modernen Pressen werden die Antriebseinrichtungen für die einzelnen Bewegungsrichtungen der Transportschienen elektrisch miteinander gekoppelt, wodurch die aufwendige mechanische Kopplung entfällt.In modern presses, the drive devices for the individual directions of movement of the transport rails are electrically coupled to one another, which eliminates the complex mechanical coupling.

Allerdings tritt hierbei der Nachteil auf, daß von den für die Querbewegung der Transportschienen vorgesehenen Antriebseinrichtungen gleichzeitig auch die auf Quertraversen vorgesehenen Antriebseinrichtungen für die Bewegung der Transportschienen in Längsrichtung mitverschoben werden müssen, wodurch die Antriebseinrichtungen für die Querbewegung der Transportschienen stärker ausgelegt werden müssen.However, here the disadvantage arises that of the drive devices provided for the transverse movement of the transport rails must at the same time also move the drive devices provided on cross members for the movement of the transport rails in the longitudinal direction, as a result of which the drive devices for the transverse movement of the transport rails must be designed more strongly.

Ein weiteres Problem, das in diesem Zusammenhang auftritt, ist ein mögliches Verkanten der Quertraversen in ihren Führungsschienen, so daß hierdurch keine einwandfreie und vor allem ruckfreie und somit genaue Bewegung der Transportschienen gewährleistet ist.Another problem that arises in this connection is a possible tilting of the crossbeams in their guide rails, so that this does not ensure that the transport rails move properly and, above all, without jerks and therefore accurately.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs erwähnten Art vorzusehen, welche die genannten Nachteile des Standes der Technik nicht aufweist, insbesondere mit der problemlose und ruckfreie Bewegungen der Transportschienen in Querrichtung, also quer zur Durchlaufrichtung der Bauteile durch die Presse, möglich sind.The present invention is therefore based on the object to provide a device of the type mentioned at the outset which does not have the disadvantages of the prior art mentioned, in particular with the problem-free and smooth movements of the transport rails in the transverse direction, that is to say transversely to the direction in which the components pass through the press, are possible.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 genannten Merkmale gelöst.According to the invention, this object is achieved by the features mentioned in the characterizing part of claim 1.

Durch das Vorsehen eines zusätzlichen Querantriebes, der synchron mit den in einem Schließkasten der Presse angeordneten Antriebsmotoren für die Horizontalbewegung der Transportschienen die Quertraversen, auf welchen die Antriebseinrichtungen für die Längsbewegung der Transportschienen angeordnet sind, aufeinanderzubewegt, ist ein Verkanten der Quertraversen in ihren Führungsschienen ausgeschlossen.The provision of an additional cross drive, which moves the cross beams on which the drive devices for the longitudinal movement of the transport rails are arranged in synchronism with the drive motors for the horizontal movement of the transport rails arranged in a lock box of the press, prevents the cross beams from tilting in their guide rails.

Der Bewegungsablauf der Transportschienen zum Aufnehmen, Transportieren und Absetzen von Werkstücken kann daher ruckfrei erfolgen.The movement sequence of the transport rails for picking up, transporting and setting down workpieces can therefore be carried out smoothly.

Nachfolgend ist anhand der Zeichnung ein Ausführungsbeispiel der vorliegenden Erfindung prinzipmäßig beschrieben.An exemplary embodiment of the present invention is described in principle below with reference to the drawing.

2 shows a view of a device according to the invention,

Fig. 3
a view of a device according to the invention, which is attached to a hanging lock case.

Bezugnehmend auf Fig. 1 ist eine Presse bzw. ein Simulator 1 dargestellt, welcher Transportschienen 2 aufweist, die in drei senkrecht aufeinanderstehenden Achsenrichtungen bewegbar sind. Die Durchlaufrichtung von Werkstücken durch die Presse 1 ist durch einen Pfeil angegeben.1, a press or a simulator 1 is shown, which has transport rails 2, which are movable in three mutually perpendicular axis directions. The direction of passage of workpieces through the press 1 is indicated by an arrow.

An den Transportschienen 2 sind Greifzeuge 3 bekannter Art angebracht, z.B. Zangen, Sauger oder dergleichen.Gripping devices 3 of known type are attached to the transport rails 2, e.g. Pliers, suction cups or the like.

In Schließkästen 4 der Presse 1 sind Antriebseinrichtungen für Bewegungen der Transportschienen 2 in Querrichtung, d.h. in horizontaler Ebene aufeinanderzu, sowie für Bewegungen in vertikaler Richtung angeordnet. So dient der in der Fig. 1 mit dem Bezugszeichen 12 gekennzeichnete und in dem Schließkasten 4 der Presse 1 angeordnete Motor als Antriebseinrichtung zum Bewegen der Transportschienen 2 aufeinanderzu, während mittels eines ebenfalls in dem Schließkasten 4 angeordneten Motors 13 Bewegungen der Transportschienen 2 in vertikaler Richtung realisierbar sind.Drive systems for movements of the transport rails 2 in the transverse direction, i.e. towards each other in the horizontal plane, and arranged for movements in the vertical direction. Thus, the motor identified in FIG. 1 by reference numeral 12 and arranged in the lock box 4 of the press 1 serves as a drive device for moving the transport rails 2 towards one another, while by means of a motor 13 also arranged in the lock box 4, movements of the transport rails 2 in the vertical direction are realizable.

Die Längsbewegungen der Transportschienen 2, also Bewegungen parallel zur Förderrichtung von Werkstücken, werden von Antriebseinrichtungen 5 ausgeführt, welche Schlitten 6 bewegen, die in Linearführungen parallel zur Durchlaufrichtung verschiebbar sind.The longitudinal movements of the transport rails 2, that is to say movements parallel to the conveying direction of workpieces, are carried out by drive devices 5 which move carriages 6, which can be displaced in linear guides parallel to the direction of passage.

Auf den Schlitten 6 sind in Querrichtung, d.h. quer zur Durchlaufrichtung, verschiebliche Traversen 7 angeordnet, die über geeignete Einrichtungen, die in dem vorliegenden Ausführungsbeispiel als Kuppelstangen 14 ausgeführt sind, mit den Transportschienen 2 verbunden sind.On the carriage 6 are in the transverse direction, i.e. Transversely to the direction of passage, slidable traverses 7 are arranged, which are connected to the transport rails 2 via suitable devices, which in the present exemplary embodiment are designed as coupling rods 14.

Die Kuppelstangen 14 sind in dem vorliegenden Ausführungsbeispiel lediglich schematisch dargestellt, können aber beispielsweise als doppelarmige Laschen ausgeführt sein.The coupling rods 14 are only shown schematically in the present exemplary embodiment, but can, for example, be designed as double-arm brackets.

Die Traversen 7 sind hierbei in Linearführungen 8 gelagert.The cross members 7 are supported in linear guides 8.

Der Antrieb der Traversen 7 erfolgt über einen zusätzlichen Querantrieb 9, welcher über eine Welle 10 eine Drehmomentenübertragungseinrichtung 11, die in dem vorliegenden Ausführungsbeispiel als Zahnriemen ausgeführt ist, antreibt, wobei an dem Zahnriemen 11 auf geeignete Art und Weise die Traversen 7 befestigt sind.The crossbeams 7 are driven via an additional transverse drive 9, which drives a torque transmission device 11, which in the present exemplary embodiment is designed as a toothed belt, via a shaft 10, the crossbeams 7 being fastened to the toothed belt 11 in a suitable manner.

Um eine synchronisierte Bewegung der Traversen 7 aufeinanderzu zu ermöglichen, ist eine der Traversen 7 über eine geeignete Einrichtung fest mit dem Zahnriemen 11 verbunden, während die zweite Traverse 7 an einem zuerst über eine Umlenkung geführten Bereich des Zahnriemens 11 befestigt ist, so daß die beiden Bereiche des Zahnriemens parallel zueinander und weitgehend horizontal verlaufend angeordnet sind. Wird nunmehr über den Querantrieb 9 die Welle 10 in Drehbewegung versetzt, so bewegen sich die beiden Traversen 7 aufeinanderzu bzw. voneinanderweg.In order to enable a synchronized movement of the crossbeams 7 towards one another, one of the crossbeams 7 is firmly connected to the toothed belt 11 by means of a suitable device, while the second crossbeam 7 is fastened to an area of the toothed belt 11 which is first guided via a deflection, so that the two Areas of the toothed belt are arranged parallel to each other and largely horizontally. If the shaft 10 is now rotated via the transverse drive 9, the two cross members 7 move towards or away from each other.

Diese Bewegung der Quertraversen 7 erfolgt synchron mit dem in dem Schließkasten 4 angeordneten und bereits erwähnten Motor 12 für den Antrieb der Transportschienen 2 in Querrichtung, wobei die Synchronisation über die Antriebseinrichtungen für die einzelnen Achsen realisiert ist. Somit wird vermieden, daß Verkantungen der Quertraversen 7 in den Linearführungen 8 auftreten, was zu ruckartigen Bewegungen der Transportschienen 2 führen würde.This movement of the crossbeams 7 takes place synchronously with the motor 12 arranged in the lock box 4 and already mentioned for driving the transport rails 2 in the transverse direction, the synchronization being implemented via the drive devices for the individual axes. This prevents canting of the crossbeams 7 in the linear guides 8, which would lead to jerky movements of the transport rails 2.

Die Drehmomentenübertragungseinrichtung, die in dem vorliegenden Ausführungsbeispiel als Zahnriemen ausgebildet ist, kann selbstverständlich auch andersartig ausgeführt sein, beispielsweise als Kette oder auch als Spindeltrieb oder Zahnstangentrieb. Allgemein kann jede geeignete Einrichtung, mittels derer eine Drehbewegung in eine Linearbewegung umgesetzt wird, verwendet werden.The torque transmission device, which in the present exemplary embodiment is designed as a toothed belt, can of course also be designed differently, for example as a chain or as a spindle drive or rack and pinion drive. In general, any suitable device by means of which a rotary movement is converted into a linear movement can be used.

Fig. 3 zeigt eine Anordnung der Vorrichtung an einem hängenden Schließkasten einer Presse bzw. eines Simulators.Fig. 3 shows an arrangement of the device on a hanging lock case of a press or a simulator.

Die Vorrichtung ist hierbei sinngemäß wie die in Zusammenhang mit der Fig. 2 beschriebene Vorrichtung aufgebaut, wobei für die jeweils selben Bauteile auch dieselben Bezugszeichen verwendet wurden. Die bereits erwähnten Vorteile und die Funktionsweise der Vorrichtung können analog auf die Vorrichtung nach der Fig. 3 übertragen werden.The device is constructed analogously to the device described in connection with FIG. 2, the same reference numerals also being used for the same components. The advantages already mentioned and the mode of operation of the device can be transferred analogously to the device according to FIG. 3.

Die beschriebene Vorrichtung kann selbstverständlich auch bei zweiachsigen Transfersystemen eingesetzt werden, falls dies erforderlich ist.The device described can of course also be used in two-axis transfer systems, if this is necessary.
