Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Ergreifen, Anheben, Transportieren und Absetzen von Zentrifugentrommeln mechanisch beschickbarer und entleerbarer Zentrifugen zum Entölen, Entwässern, Waschen, Trocknen oder sonstigen Behandeln von industriellem Stückgut, mit einer zwischen zumindest zwei Stationen verfahrbaren Laufkatze, die eine Hub-und Senkvorrichtung trägt, an derem ausfahrbarem Ende eine die Zentrifugentrommel im Bereich ihres oberen Randes erfassende Greifvorrichtung angeordnet ist.The invention relates to a device for gripping, lifting, transporting and setting down centrifuge drums for mechanically loading and emptying centrifuges for oiling, dewatering, washing, drying or other treatment of industrial piece goods, with a trolley which can be moved between at least two stations and which has a lifting and carries lowering device, on the extendable end of which a gripping device is arranged which grips the centrifuge drum in the region of its upper edge.

Eine Vorrichtung dieser Art ist bereits bekannt durch die DE-A-2 030 591.A device of this type is already known from DE-A-2 030 591.

Bei der bekannten Anlage zum Behandeln industriellen Stückguts ist eine Zentrifuge mit aushebbarer Zentrifugentrommel, eine Beschikkungsstation und eine Entieerungsstartion zugeordnet. In der Beschickungsstation wird die Zentrifugentrommel mit dem zu behandelnden Gut gefüllt, und in der Entleerungsstation wird die mit behandeltem Gut gefüllte Zentrifugentrommel auf eine Kippeinrichtung abgesetzt, in welcher die Zentrifugentrommel beispielsweise um 180° gedreht werden kann, so daß das behandelte Gut einem Behälter zugeführt wird. Die Vorrichtung zum Ergreifen, Anheben und Transportieren der Zentrifugentrommeln nimmt also eine mit zu behandelndem Gut gefüllte Trommel auf, setzt sie in die Zentrifuge ab, nimmt dann die in der Entleerungsstation befindliche leere Zentrifugentrommel auf und bewegt diese in die Beschickungsstation, bis sie die in der Zentrifuge behandelte Trommel aufnehmen und in der Entleerungsstation absetzen kann.In the known system for treating industrial piece goods, a centrifuge with a centrifuge drum that can be lifted out, a loading station and a discharge station are assigned. In the loading station, the centrifuge drum is filled with the material to be treated, and in the emptying station the centrifuge drum filled with treated material is placed on a tilting device in which the centrifuge drum can be rotated, for example, by 180 °, so that the treated material is fed to a container . The device for gripping, lifting and transporting the centrifuge drums therefore picks up a drum filled with the material to be treated, places it in the centrifuge, then picks up the empty centrifuge drum located in the emptying station and moves it into the loading station until it is in the Take up the centrifuge treated drum and deposit it in the emptying station.

Die erfindungsgemäße Vorrichtung hat den Nachteil, daß das Entleeren der Zentrifugentrommel nur in der in der Entleerungsstation befindlichen Kippvorrichtung möglich ist. In der Praxis tritt aber häufig der Wunsch auf, die mit behandeltem Gut gefüllten Zentrifugentrommeln an unterschiedlichen Stellen zu entleeren, beispielsweise ist ein selektiertes Entleeren erwünscht, wenn unterschiedliches industrielles Stückgut behandelt wird oder gleichartiges industrielles Stückgut unterschiedlich behandelt wird.The device according to the invention has the disadvantage that the centrifuge drum can only be emptied in the tilting device located in the emptying station. In practice, however, there is often a desire to empty the centrifuge drums filled with treated material at different points, for example a selective emptying is desired if different industrial general cargo is treated or similar industrial general cargo is treated differently.

Aufgabe der Erfindung ist es, die Nachteile der bekannten Vorrichtung zu vermeiden und eine Vorrichtung zu schaffen, die es ermöglicht, Zentrifugentrommeln an beliebigen Stellen einer Förderstrecke zu entleeren.The object of the invention is to avoid the disadvantages of the known device and to provide a device which enables centrifuge drums to be emptied at any point on a conveyor line.

Diese Aufgabe wird ausgehend von der eingangs beschriebenen Vorrichtung dadurch gelöst, daß in einem mit der Laufkatze verbundenen Rahmen zwei einander gegenüberliegende und radial zur Trommel vorschiebbare, die Trommel teilweise umgreifende Greifbacken angeordnet sind, weiche um eine horizontale Achse drehbar im Rahmen gelagert sind und von denen mindestens eine Greifbacke mit einem Drehantrieb versehen ist.This object is achieved on the basis of the device described in the introduction in that in a frame connected to the trolley there are two gripping jaws which are opposite one another and can be pushed radially to the drum and partially encompass the drum and which are rotatably mounted about a horizontal axis in the frame and of which at least one gripping jaw is provided with a rotary drive.

Mit Hilfe der erfindungsgemäßen Vorrichtung ist es möglich, nicht nur eine Zentrifugentrommel in den einzelnen Stationen einer Behandlungsanlage aufzunehmen oder abzusetzen, sondern auch an beliebigen Stationen zu kippen, so daß die Zentrifugentrommeln an unterschiedlichen Stellen entleert werden können. Mit Hilfe der erfindungsgemäßen Vorrichtung ist es aber auch möglich, die Zentrifugentrommeln umzufüllen oder aber auch beispielsweise, wenn durch ungleiche Beschickung Unwuchtprobleme auftreten, eine Umlagerung des zu behandelnden Gutes vorzunehmen.With the aid of the device according to the invention, it is possible not only to pick up or set down a centrifuge drum in the individual stations of a treatment plant, but also to tilt it at any station so that the centrifuge drums can be emptied at different points. With the aid of the device according to the invention, however, it is also possible to transfer the centrifuge drums or, for example, to rearrange the material to be treated if, due to uneven loading, imbalance problems arise.

Vorteilhafterweise ist an der Zentrifugentrommel mindestens ein die Trommel umfassender, nach außen vorspringender Greifring befestigt, und die Greifbacken sind mit einer zur Aufnahme des Greifringes dienenden Nut versehen. Wenn die von der Greifvorrichtung erfaßte Zentrifugentrommel von der Hub- und Senkvorrichtung in eine bestimmte Stellung angehoben ist, können die Greifbacken radial zur Trommel vorgeschoben werden, so daß die Greifbacken einen Teil des Greifringes umschließen und so die Zentrifugentrommel festhalten. Die Greifvorrichtung an der Hub- und Senkvorrichtung kann dann geöffnet werden, so daß durch Verdrehen einer Greifbacke die Zentrifugentrommel gekippt werden kann.Advantageously, at least one outwardly projecting gripping ring encompassing the drum is attached to the centrifuge drum, and the gripping jaws are provided with a groove serving to receive the gripping ring. When the centrifuge drum gripped by the gripping device is lifted into a certain position by the lifting and lowering device, the gripping jaws can be advanced radially to the drum so that the gripping jaws enclose part of the gripping ring and thus hold the centrifuge drum. The gripping device on the lifting and lowering device can then be opened so that the centrifuge drum can be tilted by turning a gripping jaw.

Weitere Merkmale der Erfindung ergeben sich aus den Patentansprüchen.Further features of the invention emerge from the patent claims.

Fig. 1 zeigt in Seitenansicht eine Ansicht zum Behandeln, zum Beispiel Galvanisieren industriellen Stückguts mit einer Zentrifuge 1, der eine Füllstation 2 für die Zentrifugentrommeln 8, eine weitere Behandlungsstation 3 und eine Entleerungsstation 4 zugeordnet sind. Zum Ergreifen, Anheben, Transportieren und Absetzen der Zentrifugentrommeln 8 dient eine mittels einer in Schienen geführten Laufkatze 5 verfahrbare Hub- und Senkvorrichtung 6, die an ihrem unteren Ende eine Greifvorrichtung 7 aufweist, mit welcher die Zentrifugentrommeln 8 an ihrem oberen, verstärkten Rand 9 erfaßt werden können. Die Hub- und Senkvorrichtung weist einen Hubwagen 25 auf, der an zwei gegenüberliegenden Seiten über je zwei Rollen 26 in vertikalen, mit der Laufkatze 5 verbundenen U-Schienen 27 geführt ist. Die Greifvorrichtung 7 besteht aus zwei verschwenkbaren Haken, die an diametral gegenüberliegenden Stellen unter den oberen Verstärkungsgrad 9 der Zentrifugentrommeln 8 greifen können.1 shows a side view of a treatment, for example galvanizing industrial piece goods with a centrifuge 1, to which a filling station 2 for the centrifuge drums 8, a further treatment station 3 and an emptying station 4 are assigned. For gripping, lifting, transporting and setting down the centrifuge drums 8, a lifting and lowering device 6 which can be moved by means of a trolley 5 guided in rails and has a gripping device 7 at its lower end, with which the centrifuge drums 8 are gripped at their upper, reinforced edge 9 can be. The lifting and lowering device has a lifting carriage 25, which on two opposite sides via two rollers 26 in vertical U-rails 27 connected to the trolley 5 is led. The gripping device 7 consists of two pivotable hooks, which can grip at diametrically opposite points under the upper degree of reinforcement 9 of the centrifuge drums 8.

Die Füllstation 2 besteht beispielsweise aus einem Drehteller 20, der zwei oder mehr Zentrifugentrommeln 8 aufnimmt und der mittels eines Drehantriebes 21 um die Achse 22 drehbar ist und die gefüllten Zentrifugentrommeln 8 in eine Aufnahmestellung bewegt. Die verfahrbare Hub-und Senkvorrichtung setzt auf diesen Drehteller leere Zentrifugentrommeln 8 ab und nimmt eine mit zu behandelndem industriellen Stückgut gefüllte Zentrifugentrommel 8 auf und transportiert sie zu einer Zentrifuge 1 oder 3 und setzt sie dort ab. In der Zentrifuge 1 kann das zu behandelnde Gut entölt und/oder gewaschen und/ oder gerommelt und/oder getrocknet werden. Nach der Behandlung kann die Zentrifugentrommel 8 der Zentrifuge 1 entnommen und einerweiteren Behandlungsstation 3 oder einer Entleerungsstation 4 zugeführt werden. Über der Entleerungsstation 4 kann die Zentrifugentrommel 8 mit Hilfe von um die horizontale Achse 16 drehbaren Greifbacken 11, 12 um 180° gedreht werden, so daß der Trommelinhalt über eine Rutsche 23 einem nicht dargestellten Förderwagen oder dergleichen zugeführt werden kann.The filling station 2 consists, for example, of a turntable 20 which receives two or more centrifuge drums 8 and which can be rotated about the axis 22 by means of a rotary drive 21 and moves the filled centrifuge drums 8 into a receiving position. The movable lifting and lowering device places empty centrifuge drums 8 on this turntable and picks up a centrifuge drum 8 filled with industrial piece goods to be treated and transports them to a centrifuge 1 or 3 and places them there. The material to be treated can be de-oiled and / or washed and / or tumbled and / or dried in the centrifuge 1. After the treatment, the centrifuge drum 8 can be removed from the centrifuge 1 and fed to a further treatment station 3 or an emptying station 4. About the emptying station 4, the centrifuge drum 8 can be rotated by 180 ° with the help of rotatable about the horizontal axis 16 gripping jaws 11, 12, so that the drum contents can be fed via a chute 23 to a trolley, not shown, or the like.

Wie insbesondere die Fig. 3 zeigt, sind die Greifbacken 11, 12 in einem mit der Laufkatze 5 verbundenen Rahmen 10 angeordnet und mittels pneumatischer oder hydraulischer Arbeitszylinder 13 radial zur Zentrifugentrommel 8 vorschiebbar. Die Greifbacken 11 und 12 umfassen die Zentrifugentrommel 8, so daß die Greifeinrichtung 7 am unteren Ende der Hub- und Senkvorrichtung geöffnet werden kann. In der Entleerungsstation kann mindestens eine Greifbakke 12 mit Hilfe eines Drehantriebes 14 um beispielsweise 180° gedreht werden, um den Trommelinhalt auszukippen. An der Zentrifugentrommel 8 ist mindestens ein die Trommel 8 umgebender Greifring 15 befestigt, und die Greifbakken 11, 12, weisen eine den Greifring 15 aufnehmende Nut 17 auf. Der Greifring 15 und die Nut 17 in den Greifbacken 11, 12 bewirken, daß die Zentrifugentrommel 8 auch bei Anwendung nur geringer Anstellkräfte zuverlässig von den Greifbacken 11, 12 gehalten wird.3 shows, in particular, the gripping jaws 11, 12 are arranged in a frame 10 connected to the trolley 5 and can be advanced radially to the centrifuge drum 8 by means of pneumatic or hydraulic working cylinders 13. The gripping jaws 11 and 12 enclose the centrifuge drum 8, so that the gripping device 7 can be opened at the lower end of the lifting and lowering device. In the emptying station, at least one gripping jaw 12 can be rotated by means of a rotary drive 14, for example by 180 °, in order to tip out the contents of the drum. At least one gripping ring 15 surrounding the drum 8 is fastened to the centrifuge drum 8, and the gripping jaws 11, 12 have a groove 17 which receives the gripping ring 15. The gripping ring 15 and the groove 17 in the gripping jaws 11, 12 have the effect that the centrifuge drum 8 is reliably held by the gripping jaws 11, 12 even when only small contact forces are used.

Der Drehantrieb 14 treibt über eine Gliederkette eine im Rahmen 10 über Wälzkörper drehbar gelagerte Hülse 18 an, in welcher der Schaft 19 der Greifbacke 12 unverdrehbar, aber axial verschiebbar gelagert ist.The rotary drive 14 drives, via a link chain, a sleeve 18 which is rotatably mounted in the frame 10 via rolling elements and in which the shaft 19 of the gripping jaw 12 is non-rotatably but axially displaceably mounted.

Der Greifring 15 ist zweckmäßigerweise in Höhe des Schwerpunktes an einer mit zu behandelndem Gut gefüllten Zentrifugentrommel 8 angeordnet. Da die Höhe dieses Schwerpunktes von der Art des zu behandelnden Gutes und der Füllhöhe abhängig ist, kann es vorteilhaft sein, jede Zentrifugentrommel mit zwei oder drei Greifringen 15 auszurüsten, die im Abstand voneinander in der unteren Hälfte der Trommel angebracht sind.The gripping ring 15 is expediently arranged at the center of gravity on a centrifuge drum 8 filled with material to be treated. Since the height of this center of gravity depends on the type of material to be treated and the filling height, it can be advantageous to equip each centrifuge drum with two or three gripping rings 15 which are arranged at a distance from one another in the lower half of the drum.

Die Hub- und Senkvorrichtung 6 ist mit Schaltern, Sensoren oder dergleichen ausgerüstet, die den Vorschubantrieb der Greifbacken 11, 12 freigeben, wenn sich ein Greifring 15 der Zentrifugentrommel 8 in Höhe der Greifbacken 11, 12 befindet. Die Bewegungen der Laufkatze 5, der Hub- und Senkvorrichtung 6, der Greifvorrichtung 7 und der Greifbacken 11, 12 können für verschiedene Behandlungsabläufe programmiert werden.The lifting and lowering device 6 is equipped with switches, sensors or the like which release the feed drive of the gripping jaws 11, 12 when there is a gripping ring 15 of the centrifuge drum 8 at the level of the gripping jaws 11, 12. The movements of the trolley 5, the lifting and lowering device 6, the gripping device 7 and the gripping jaws 11, 12 can be programmed for different treatment processes.
