Description

Die Erfindung betrifft eine Einrichtung zum dreidimensionalen Antrieb von Greiferschienen gemäß Oberbegriff von Anspruch 1.The invention relates to a device for the three-dimensional drive of gripper rails according to the preamble of claim 1.

Einrichtungen dieser Art in einer Mehrständerpresse dienen der Umsetzbewegung der Blechteile, dem Einlegen in Werkzeuge, dem Entnehmen aus diesen und dem Transport in die folgende Bearbeitungs- oder Entnahmestufe. Generell besteht hier die Forderung, die Bewegungsantriebe der Greiferschienen in den drei Achsen (dreidimensional) nicht von Kurven abzugreifen. Um bei Werkstück- bzw. Werkzeugwechsel die Presse auf die neuen Bedingungen einstellen zu können, bedurfte es entweder individueller Nocken, oder es wurde von Maximal-Wegen ausgegangen, die von einem einzigen Nockensatz erreicht werden.Devices of this type in a multi-column press are used for moving the sheet metal parts, inserting them into tools, removing them from them and transporting them to the following processing or removal stage. In general, there is a requirement here that the movement drives of the gripper rails in the three axes (three-dimensional) should not be tapped from curves. In order to be able to adjust the press to the new conditions when changing the workpiece or tool, either individual cams were required or maximum paths were assumed that can be achieved with a single set of cams.

In der DE-C2-33 29 900 ist eine Einrichtung zum dreidimensionalen Transfer beschrieben, bei der die Bewegungen von Greiferschienen in den drei Achsen durch Servo-Motore bewirkt wird. Die Motore befinden sich nicht im unmittelbaren Wirkbereich der Greiferschienen. Es sind Getriebeketten und -gestänge erforderlich, die bei den geforderten hohen Beschleunigungen bei Umsetzbewegungen von z.B. 16 Teilen und mehr je Minute zu Ungenauigkeiten in den Achsen führen. Die Drehbewegung des Servo-Motors für die Spann-Lösebewegung wird über eine Ritzel-Zahnstangenverbindung auf horizontal und quer zur Umsetzbewegung bewegliche Schlitten übertragen. Beschrieben ist ein Antrieb des Spannmechanismus unter Verwendung eines Gleichspannungs-Servo-Motors, der außerhalb des den Schließkasten ausmachenden Gehäuses gelagert ist und dessen Drehbewegung über ein Reduziergetriebe und einen Steuerriemen mit einer Kegelradanordnung verbunden ist. Diese befindet sich an der Unterseite des Gehäuses und weist eine Ausgangswelle auf zum Antrieb des Ritzels der Ritzel-Zahnstangenkombination für die Spann-Lösebewegung.DE-C2-33 29 900 describes a device for three-dimensional transfer in which the movements of gripper rails in the three axes are brought about by servo motors. The motors are not in the immediate effective area of the gripper rails. Gear chains and linkages are required, which lead to inaccuracies in the axes at the required high accelerations with repositioning movements of, for example, 16 parts and more per minute. The rotary movement of the servo motor for the clamping / releasing movement is transmitted via a pinion-rack connection to slides that can move horizontally and transversely to the transfer movement. What is described is a drive of the tensioning mechanism using a DC servo motor, which is mounted outside the housing that makes up the lock case and whose rotational movement is connected to a bevel gear arrangement via a reduction gear and a control belt. This is located on the underside of the housing and has an output shaft for driving the pinion of the pinion-rack combination for the tension-release movement.

In der japanischen Offenlegungschrift 59-197325, Appl. No. 58-71162, ist der Antrieb von Greiferschienen dargestellt, die in zwei Achsen bewegt werden. Die Spann-Lösebewegung der Greiferschienen wird von einem reversiblen Servo-Motor bewirkt, der außerhalb einer horizontal in Umsetzrichtung bewegbaren Konsole angeflanscht ist und zugleich mit dieser in Umsetzrichtung bewegt werden muß. Die Motorwelle ist einseitig aus dem Motor als Spindel herangeführt. Die Spindel weist zum einen Links-, zum anderen Rechtsgewinde auf, die mit den Greiferschienen tragenden, querverschieblichen Schlitten zusammenwirken.In Japanese laid-open publication 59-197325, Appl. No. 58-71162, the drive of gripper rails is shown, which are moved in two axes. The clamping and releasing movement of the gripper rails is effected by a reversible servo motor which is flanged outside a bracket which can be moved horizontally in the transfer direction and at the same time must be moved in the transfer direction with it. The motor shaft is brought out of the motor as a spindle on one side. On the one hand, the spindle has left-hand and on the other hand, right-hand threads, which interact with the cross-sliding carriages that carry the gripper rails.

Auch in der DE-A1-32 38 729 sind gleiche Mittel, wie zuvor beschrieben, dargestellt. Die Servo-Motoren für zwei Bewegungen des dreidimensionalen Bewegungsantriebs der Greiferschienen sind zwar mittig, aber unterhalb der Greiferschienen in einem unteren Teil des Schließkastens angeordnet.The same means as described above are also shown in DE-A1-32 38 729. The servo motors for two movements of the three-dimensional movement drive of the gripper rails are arranged in the center, but below the gripper rails in a lower part of the lock case.

Demgegenüber ist es Aufgabe der Erfindung, den Motor für die Spann-Lösebewegungen der Greiferschienen zwischen den Greiferschienen und den diese tragenden Schlitten anzuordnen, um so den durch die Größe der Werkzeuge in den Bearbeitungsstufen von den Greiferschienen beim Spannen nicht überfahrbaren Weg zu nutzen.In contrast, it is an object of the invention to arrange the motor for the clamping-releasing movements of the gripper rails between the gripper rails and the carriage carrying them, so as to use the path that cannot be traversed by the gripper rails during clamping due to the size of the tools in the processing stages.

Diese Aufgabe ist gelöst durch die Merkmale des Kennzeichens von Anspruch 1. Anspruch 2 kennzeichnet eine vorteilhafte Ausbildung nach der Erfindung.This object is achieved by the features of the characterizing part of claim 1. Claim 2 characterizes an advantageous embodiment according to the invention.

Von besonderem Vorteil ist die Anordnung des Motors in Höhe von Greiferschienen und Schlitten, da sich hierdurch ein Direkt-Antrieb für die Spann-Lösebewegung realisieren läßt. Es werden keine Antriebsmittel, Getriebegestänge u. dgl. in den drei Achsen bewegt. Es wurde ein Servo-Motor mit beidseitiger Antriebswelle in den konsolartigen Aufbau integriert. Durch die dadurch bewirkte symmetrische Ausbildung wird die Torsionssteifigkeit erhöht. Der Schließkasten bildet so eine funktionsfähige, komplette Baueinheit.The arrangement of the motor at the height of the gripper rails and slide is particularly advantageous, since this enables a direct drive for the clamping / releasing movement to be implemented. There are no drive means, gear linkage, etc. Like. Moved in the three axes. A servo motor with a drive shaft on both sides was integrated into the console-like structure. The resulting symmetrical design increases torsional rigidity. The lock box thus forms a functional, complete unit.

Anhand eines Ausführungsbeispiels in der Zeichnung soll im folgenden die Erfindung näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment in the drawing.

In den Figuren sind gleiche Teile und Baugruppen gleich numeriert. Mit 1 ist ein Schließkasten von mehreren Schließkästen einer Mehrständerpresse positioniert. Von der Presse ist nur ein Ständerpaar mit den Ständern 2 gezeigt. Der Schließkasten 1 ist über Konsolbleche 16 pressentischseitig aufgestellt. In den Konsolblechen 16 befinden sich Stirnräder 21 einer Motorwelle 19 eines Motors 17 für das Heben- und Senken von Greiferschienen 3. Die Stirnräder 21 wirken mit je einem Stirnrad 22 zusammen, das jeweils direkt auf eine in gestellseitigen Lagern 15 geführte Zahhstange 14 und über ein weiteres Stirnrad 22 auf eine zweite in Lagern 15 geführte Zahnstange 14 wirkt. Die Drehbewegung des Motors 17 wird so in eine Hebe-Senkbewegung (Doppelpfeil 28) von Trägerblechen 13 umgesetzt. Auf den Trägerblechen 13 sind Schienen 12 für in diesen quer zur Umsetzrichtung 27 bewegbare Schlitten 11 befestigt. Die Hebe-Senkbewegung des Motors 17 wird so auf die Greiferschienen übertragen. Die Schlitten 11 tragen hierfür Distanzbolzen 9, die nach oben durch Querschlitten 7 hindurchgeführt sind und an den oberen Enden Führungen 4 für die in diesen geführten Greiferschienen 3 tragen. Die Trägerbleche 13 sind durch Ausbalancierzylinder 20 abgestützt.In the figures, the same parts and assemblies are numbered the same. With 1, a lock case of several lock cases of a multi-column press is positioned. From the press, only a pair of stands with stands 2 is shown. The lock case 1 is set up on console plates 16 on the press table side. In the bracket plates 16 there are spur gears 21 of a motor shaft 19 of a motor 17 for the raising and lowering of gripper rails 3. The spur gears 21 cooperate with a spur gear 22, each of which directly on a rack 14 guided in frame-side bearings 15 and via a Another spur gear 22 acts on a second rack 14 guided in bearings 15. The rotational movement of the motor 17 is thus converted into a lifting and lowering movement (double arrow 28) of the carrier plates 13. Rails 12 for carriages 11 which can be moved transversely to the transfer direction 27 are fastened on the carrier plates 13. The lifting and lowering movement of the motor 17 is thus transmitted to the gripper rails. For this purpose, the slides 11 carry spacer bolts 9, which are guided upwards through cross slides 7 and carry guides 4 for the gripper rails 3 guided in them at the upper ends. The carrier plates 13 are supported by balancing cylinders 20.

Die Konsolbleche 16 tragen im oberen Bereich ein Gestell 6. Das Gestell 6 ist mit Führungen 8 versehen, in denen die Querschlitten 7 in Spann- und Löserichtung 29 verschieblich sind. Die Verschiebebewegungen der Querschlitten 7 werden bewirkt durch einen in diesem Aufbau in Höhe der Querschlitten 7 gelagerten Servo-Motor 18, dessen Welle beidseitig aus diesem herausgeführt ist. Die Wellenteile sind als Spindeln 23 mit Rechtsgewinde bzw. mit Linksgewinde versehen. Die Gewinde wirken mit Schloßmuttern 24, 26, Käfigmuttern od. dgl. Spindelmuttern in bzw. an den Querschlitten 7 zusammen. Der Bewegungsantrieb der Greiferschienen 3 in Umsetzrichtung 27 erfolgt z. B. in der aus dem genannten Stand der Technik genannten Weise. Die Hebe-Senkbewegung der Greiferschienen 3 erfolgt, ausgehend von dem Motor 17, Motorwelle 19 und Stirnrad,. Ritzel-, Zahnstangentrieb 21, 22, 14 und Schlitten 11 vermittels Distanzbolzen 9 auf die Führungen 4, wobei sich hierfür die Führungen 12 für die Schlitten 11 über die Spann-Lösebewegungsstrecke der Greiferschienen 3 erstrecken müssen. In gleicher Weise sind auch die Führungen 8 auszulegen.The console plates 16 carry a frame 6 in the upper region. The frame 6 is provided with guides 8 in which the cross slides 7 can be displaced in the tensioning and releasing direction 29. The displacement movements of the cross slides 7 are brought about by a servo motor 18 mounted in this structure at the level of the cross slides 7, the shaft of which is guided out of it on both sides. The shaft parts are provided as spindles 23 with a right-hand thread or with a left-hand thread. The threads interact with lock nuts 24, 26, cage nuts or the like. Spindle nuts in or on the cross slide 7. The movement drive of the gripper rails 3 takes place in the conversion direction 27 z. B. in the manner mentioned from the prior art. The lifting and lowering movement of the gripper rails 3 takes place starting from the motor 17, motor shaft 19 and spur gear. Pinion, rack and pinion drive 21, 22, 14 and slide 11 by means of spacers 9 on the guides 4, for which purpose the guides 12 for the slide 11 must extend over the tension-release movement path of the gripper rails 3. The guides 8 are also to be designed in the same way.
