Abstract

The transfer device has two horizontal spaced-out transporting rails (2) which can be moved horizontally and vertically towards each other by motors. The motors are on a traverse (7) and link the rails to the traverse. A levelling guide (10) is fitted between the transporting rails and the motors for the horizontal movement of them. This guide has at least two braces (11, 12) and a twin-arm tie (13) with three connecting points (15-19). Each brace is linked to one point on the traverse side. The other end of the brace is connected to the connection point (18, 19) of the twin-arm tie. Its third point is pivoted to the rail.

Description

Die Erfindung betrifft eine Vorrichtung zum Transfer von Werkstücken durch eine Folge von Bearbeitungsstationen einer Presse, eines Simulators oder dergleichen Bearbeitungs- oder Einrichtmaschine 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 of a press, a simulator or the like processing or setting machine 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 gear with a rack extending in the longitudinal direction of the transport rail, the deflection wheel cooperates with a toothed belt extending in the longitudinal direction of the transport rail, a tap point being 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 connected to the transport rail is articulated.

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 zufolge 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 means that the entire device has to be assembled in a relatively complex manner and has 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 correctly and, above all, without jerks and therefore accurately.

Aus diesem Grunde sind zusätzliche Querantriebe vorgesehen, welche synchron mit dem in einem Schließkasten der Presse angeordneten Antriebsmotor für die Horizontalbewegung der Transportschienen die Quertraversen, auf welchen die Antriebseinrichtungen für die Längsbewegung der Transportschienen angeordnet sind, aufeinanderzu bewegen, so daß ein Verkanten der Quertraverse in ihren Führungsschienen ausgeschlossen ist.For this reason, additional cross drives are provided which move the cross beams, on which the drive devices for the longitudinal movement of the transport rails are arranged, towards one another in synchronism with the drive motor arranged in a lock box of the press for the horizontal movement of the transport rails, so that the cross beam is tilted in their Guide rails is excluded.

Da sich die Transportschienen in der horizontalen Ebene jedoch unter Umständen gleichzeitig in zwei Achsenrichtungen bewegen, d.h. sie bewegen sich auf einer Kreisbahn, können die Antriebseinrichtungen nicht über einfache Koppelglieder, wie beispielsweise Stangen, mit den Transportschienen verbunden werden, da sich ansonsten die Koppelglieder verkanten oder verspannen und sehr hohe Spannungen im Werkstoff der Koppelglieder auftreten, welche eventuell sogar zur Zerstörung der Koppelglieder führen können.However, since the transport rails in the horizontal plane may move simultaneously in two axis directions, i.e. they move on a circular path, the drive devices cannot be connected to the transport rails via simple coupling elements, such as rods, because otherwise the coupling elements will tilt or become tense and very high stresses will occur in the material of the coupling elements, which may even destroy the coupling elements being able to lead.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Transfer von Werkstücken durch eine Folge von Bearbeitungsstationen einer Presse, eines Simulators oder dergleichen Bearabeitungs- oder Einrichtmaschine vorzusehen, welche die beschriebenen Nachteile des Standes der Technik vermeidet, insbesondere mit der eine problemlose Anbindung der Antriebsmotoren an die Transportschienen möglich ist.The present invention is therefore based on the object of providing a device for transferring workpieces through a series of processing stations of a press, a simulator or the like processing or setting machine, which avoids the disadvantages of the prior art described, in particular with the problem-free connection of the Drive motors to the transport rails is 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 einer derartigen Ausgleichsführung kann auf einfache Art und Weise eine Verbindung zwischen den Transportschienen und den auf der Traverse angeordneten Motoren für die Horizontalbewegung der Transportschienen hergestellt werden, so daß ein einwandfreier und problemloser Betrieb der Transportschienen sichergestellt ist.By providing such a compensation guide, a connection between the transport rails and the motors arranged on the crossbeam for the horizontal movement of the transport rails can be established in a simple manner, so that correct and problem-free operation of the transport rails is ensured.

Die Bewegung der Transportschienen auf einer Kreisbahn bei einer Bewegung der Transportschienen gleichzeitig in zwei Achsenrichtungen wird durch die beschriebene Anordnung ausgeglichen, so daß ein Verkanten oder Verspannen der Transportschienen ausgeschlossen ist.The movement of the transport rails on a circular path when the transport rails move simultaneously in two axis directions is compensated for by the arrangement described, so that tilting or bracing of the transport rails is excluded.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und dem nachfolgend anhand der Zeichnung prinzipmäßig beschriebenen Ausführungsbeispiel.Advantageous refinements and developments of the invention result from the subclaims and the exemplary embodiment described in principle below with reference to the drawing.

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.On the transport rails 2 gripping devices 3 known type are attached, for. B. 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.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.

Die Längsbewegungen der Transportschienen 2 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 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 nachfolgend beschriebene Einrichtungen mit den Transportschienen 2 verbunden sind.On the carriage 6 are in the transverse direction, i.e. Transversely to the direction of movement, movable cross members 7 are arranged, which are connected to the transport rails 2 via suitable devices described below.

Die Traversen 7 sind hierbei in Linearführungen 8 gelagert. Die Traversen 7 werden von einem zusätzlichen Querantrieb 9 synchron zu der Bewegung der Transportschienen 2 bewegt.The cross members 7 are supported in linear guides 8. The traverses 7 are moved by an additional transverse drive 9 synchronously with the movement of the transport rails 2.

Eine Verbindung zwischen den Traversen 7 und den Transportschienen 2 erfolgt über in der Fig. 1 schematisch dargestellte Ausgleichsführungen 10, welche in den Figuren 2 und 3 näher dargestellt sind. Jede einzelne Ausgleichsführung weist zwei Streben 11, 12 auf, welche jeweils einerseits traversenseitig, also an der der Traverse 7 zugewandten Seite, über einen oberen Anlenkpunkt 15 und einen unteren Anlenkpunkt 16 mit der Traverse 7 und andererseits über Anlenkpunkte 17, 18 mit einer dreiecksförmig ausgeführten doppelarmigen Läsche 13 gelenkig verbunden sind, wie in den Fig. 2 und 3 dargestellt.A connection between the traverses 7 and the transport rails 2 takes place via compensating guides 10 which are shown schematically in FIG. 1 and which are shown in more detail in FIGS. 2 and 3. Each individual compensation guide has two struts 11, 12, each of which on the one hand on the traverse side, i.e. on the side facing the traverse 7, has an upper articulation point 15 and a lower articulation point 16 with the cross member 7 and, on the other hand, via articulation points 17, 18 with a triangular shape double-arm bracket 13 are articulated, as shown in FIGS. 2 and 3.

Die doppelarmige Lasche 13 wiederum ist an einem Ende mit einem dritten Anlenkpunkt 19 versehen und über einen Bolzen 14 gelenkig mit der Transportschiene 2 verbunden.The double-arm bracket 13 in turn is provided at one end with a third articulation point 19 and is connected in an articulated manner to the transport rail 2 via a bolt 14.

Durch die beschriebene Anordnung ist eine Ausgleichsführung realisiert, mittels welcher ein Verkanten oder Verspannen der Transportschienen 2 und/oder der Traverse 7 vermieden wird.A compensation guide is realized by the arrangement described, by means of which tilting or bracing of the transport rails 2 and / or the crossmember 7 is avoided.

In dem vorliegenden Ausführungsbeispiel ist vorgesehen, daß an jeder einzelnen Transportschiene 2 seitlich jeweils eine doppelarmige Lasche 13 vorgesehen ist.In the present exemplary embodiment it is provided that a double-armed tab 13 is provided on the side of each individual transport rail 2.

Es ist jedoch selbstverständlich auch möglich, jeweils nur eine doppelarmige Lasche 13 mit den entsprechenden Streben 11, 12 pro Transportschiene 2 vorzusehen.However, it is of course also possible to provide only one double-arm bracket 13 with the corresponding struts 11, 12 per transport rail 2.

Ein zweites Ausführungsbeispiel einer Ausgleichsführung ist in den Fig. 4 und 5 dargestellt. Bereits in Zusammenhang mit der Beschreibung der vorhergehenden Figuren eingeführte Bezugszeichen sollen nachfolgend für dieselben Bauteile verwendet werden.A second embodiment of a compensation guide is shown in Figs. 4 and 5. Reference symbols already introduced in connection with the description of the preceding figures are to be used below for the same components.

Anstatt einer dreiecksförmig ausgeführten Lasche wird hierbei eine gerade Lasche 20 verwendet, an deren Enden in den Anlenkpunkten 17, 18 jeweils die Streben 11 und 12 gelenkig gelagert sind, während die den Transportschienen 2 abgewandten Enden der Streben 11 und 12 über den oberen Anlenkpunkt 15 und den unteren Anlenkpunkt 16 mit der Traverse 7 gelenkig verbunden sind.Instead of a triangular flap, a straight flap 20 is used, at the ends of which the struts 11 and 12 are articulated at the articulation points 17, 18, while the ends of the struts 11 and 12 facing away from the transport rails 2 are via the upper articulation point 15 and the lower pivot point 16 are articulated to the cross member 7.

Die gerade Lasche 20 selbst ist mittig über den dritten Anlenkpunkt 19 mit der Transportschiene 2 gelenkig verbunden.The straight tab 20 itself is connected in an articulated manner to the transport rail 2 via the third articulation point 19.

Es soll noch darauf hingewiesen werden, daß die Streben 11, 12 sich überkreuzend angeordnet sind, d.h. die Strebe 11 ist einerseits mit dem obenliegenden Anlenkpunkt 17 der geraden Lasche 20 und andererseits mit dem unteren Anlenkpunkt 16 an der Traverse 7 verbunden, während die andere Strebe 12 an dem untenliegenden Anlenkpunkt 18 der Lasche 20 und an dem oberen Anlenkpunkt 15 der Traverse 7 angelenkt ist.It should also be pointed out that the struts 11, 12 are arranged crossing one another, i.e. the strut 11 is connected on the one hand to the upper articulation point 17 of the straight link 20 and on the other hand to the lower articulation point 16 on the cross member 7, while the other strut 12 is articulated to the lower articulation point 18 of the link 20 and to the upper articulation point 15 of the cross member 7 is.

Auch mit der in dem zweiten Ausführungsbeispiel beschriebenen Anordnung kann auf einfache Weise die Bewegung der Transportschienen auf einer Geraden bzw. linear realisiert werden, wobei ein Verspannen oder Verkanten der Transportschienen jedoch ausgeschlossen ist.Even with the arrangement described in the second exemplary embodiment, the movement of the transport rails on a straight line or in a linear manner can be implemented in a simple manner, but tensioning or tilting of the transport rails is excluded.
