Description

Die Erfindung bezieht sich auf einen Faßgreifer mit einem Faßgreiferkopf gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a drum gripper with a drum gripper head according to the preamble of the main claim.

Faßgreifer mit einem Faßgreiferkopf sind bekannt, wobei der Faßgreiferkopf aus einem Greifermechanismus besteht, der eine Ober- und eine Unterbacke aufweist, die beim Anfahren und Anheben des Fasses automatisch fest um den Falzrand des Fasses greifen. Beim Absetzen öffnet sich der Greiferkopf selbsttätig, so daß eine praktische, sichere und wirtschaftliche Lösung für das Verladen, Transportieren und Stapeln von stehenden Metall- und Kunststoff- fässern mit einem sogenannten L-Ring gegeben wird. Bei einer in der DE-B-10 25 336 beschriebenen Einrichtung sind die Oberbacke und die Unterbacke über Gelenkverbindungen an einem Träger ortsfest angeordnet und miteinander über einen Führungshebel verbunden. Diese Anordnung ist wenig anpassungsfähig und stellt eine relativ starre Baueinheit dar, die leicht zum Beschädigen des Fasses führen kann und, wenn sie selbst beschädigt wird, nur insgesamt ausgewechselt und repariert werden kann. Da aufgrund der ständig erfolgenden Bewegungen und erheblichen Gewichte leicht Verschleißerscheinungen auftreten, ist die Reparaturfreundlichkeit eines Faßgreiferkopfes ein wichtiges Merkmal für solche Konstruktionen.Drum grippers with a drum gripper head are known, the drum gripper head consisting of a gripper mechanism which has an upper and a lower jaw which automatically grip firmly around the folded edge of the drum when the drum is started and raised. The gripper head opens automatically when it is set down, so that a practical, safe and economical solution for loading, transporting and stacking standing metal and plastic drums is provided with a so-called L-ring. In a device described in DE-B-10 25 336, the upper jaw and the lower jaw are arranged in a fixed manner via articulated connections on a carrier and connected to one another via a guide lever. This arrangement is not very adaptable and is a relatively rigid unit that can easily damage the barrel and, if damaged itself, can only be replaced and repaired as a whole. Since wear and tear easily occurs due to the constant movements and considerable weights, the ease of repair of a drum gripper head is an important feature for such constructions.

Aus der gattungsbildenden US-A-42 43 354 ist eine Anordnung bekanntgeworden, bei welcher eine feste Unterbacke vorgesehen wird, während sich die Oberbacke gegenüber der Unterbacke verstellen und verschieben kann. Hierzu sind die Unterbacke und die Oberbacke an einem Führungshebel angeordnet. Die Unterbacke ist an dem Führungshebel starr vorgesehen, während sich die Oberbacke gegenüber dem Führungshebel um ein Drehlager, das als kurzes Langloch ausgebildet ist, drehen kann. Der Führungshebel ist über eine Hebelverbindung mit dem Anbaugerät verbunden. Bei Anfahren des Fasses, beispielsweise über einen Gabelstapler, ist ein Ausweichen des Führungshebels nicht möglich und somit ist die Anpaßbarkeit des Faßgreiferkopfes an unterschiedliche Faßformen nur sehr gering und der Führungshebel selbst stellt ein starres Widerlager bei Anfahren des Fasses dar. Bei dieser bekannten Einrichtung wirkt im Arbeitsfall - wenn sich die Achse nach hinten im Langloch verschoben hat - die gesamte Tragvorrichtung als Parallelogramm, so daß Erschütterungen beim Transport des ergriffenen Fasses dazu führen, daß sich die Greifnase von ihrer Anlage lösen kann und das Faß freigibt. Diese Erschütterungen sind beim Überfahren von Gleisanlagen oder sonstigen Unebenheiten im Transportbereich, beispielsweise einer Hafenanlage oder einem Fabrikationsbereich, nicht zu vermeiden.From the generic US-A-42 43 354 an arrangement has become known in which a fixed lower jaw is provided, while the upper jaw can adjust and move relative to the lower jaw. For this purpose, the lower jaw and the upper jaw are arranged on a guide lever. The lower jaw is rigidly provided on the guide lever, while the upper jaw can rotate relative to the guide lever about a pivot bearing which is designed as a short elongated hole. The guide lever is connected to the attachment via a lever connection. When starting the barrel, for example using a forklift, it is not possible to evade the guide lever and thus the adaptability of the barrel gripper head to different barrel shapes is very low and the guide lever itself represents a rigid abutment when starting the barrel Work case - when the axis has moved backwards in the slot - the entire carrying device as a parallelogram, so that vibrations during transport of the gripped barrel lead to the gripping nose being able to detach from its system and the barrel to be released. These vibrations cannot be avoided when driving over track systems or other unevenness in the transport area, for example a port system or a manufacturing area.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsbildende Einrichtung dahingehend zu verbessern, daß die Anpaßbarkeit des Faßgreiferkopfes an unterschiedliche Faßausbildungen erhöht, die Reparaturmöglichkeit des Faßgreiferkopfes vereinfacht und gleichzeitig die Halterung des Fasses sicherer gestaltet wird.The invention has for its object to improve the generic device in such a way that the adaptability of the drum gripper head to different barrel designs increases, the possibility of repairing the drum gripper head is simplified and at the same time the holder of the barrel is made safer.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Merkmale des kennzeichnenden Teiles des Hauptanspruches gelöst.This object on which the invention is based is achieved by the features of the characterizing part of the main claim.

Vorteilhafte Ausgestaltungen der erfindungsgemäßen Lehre sind in den Unteransprüchen erläutert.Advantageous embodiments of the teaching according to the invention are explained in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung beschrieben. Die Zeichnung zeigt dabei in

  • Figur 1 eine Seitenansicht eines Faßgreiferkopfes an einem Anbaugerät, wobei der Faßgreiferkopf in der Greiflage steht, in
  • Figur 2 eine Teildraufsicht auf die Vorrichtung gemäß Fig. 1 und in den
  • Figuren 3, 4 und 5 die verschiedenen Arbeitsstellungen des eigentlichen Faßgreifers beim Ergreifen des Fasses.
An embodiment of the invention is described below with reference to the drawing. The drawing shows in
  • Figure 1 is a side view of a drum gripper head on an attachment, the drum gripper head is in the gripping position, in
  • Figure 2 is a partial plan view of the device of FIG. 1 and in the
  • Figures 3, 4 and 5, the various working positions of the actual barrel gripper when gripping the barrel.

In der Zeichnung ist mit 1 ein zu handhabendes Faß bezeichnet und mit 2 ein Anbaugerät, das beispielsweise mit Aufnahmetaschen 3 für die Hubelemente einer Hubeinrichtung ausgerüstet ist. Das Anbaugerät 2 trägt eine Stützvorrichtung 4, die beispielsweise aus zwei Stützstreben 5 besteht, von denen eine Stützstrebe 5 in der Zeichnung erkennbar ist. Die Stützstreben 5 sind bei 6 gelenkig im unteren Bereich des Anbaugerätes 2 gelagert und führen sich im oberen Bereich zwischen zwei Führungen 7 und 8, beispielsweise entgegen einer Feder 9, wobei die Führung durch Gleitbolzen 10 und 11 ermöglicht wird, die in entsprechenden in der Zeichnung erkennbaren Langlochführungen gleiten.In the drawing, 1 denotes a barrel to be handled and 2 an attachment, which is equipped, for example, with receiving pockets 3 for the lifting elements of a lifting device. The attachment 2 carries a support device 4, which consists for example of two support struts 5, of which a support strut 5 can be seen in the drawing. The support struts 5 are articulated at 6 in the lower region of the attachment 2 and run in the upper region between two guides 7 and 8, for example against a spring 9, the guide being made possible by sliding bolts 10 and 11, which are shown in the corresponding in the drawing slidable slot guides.

Von der Stützvorrichtung 4 wird schwenkbar bei 12 eine Oberbacke 14 getragen, die an ihrem der Stützvorrichtung 4 abgewandten Ende eine Greifnase 15 aufweist. Die Oberbacke 14 trägt schwenkbar bei 16 einen Schwenkhebel 17, der fest eine Unterbacke 18 aufweist, wobei das Zusammenwirken zwischen Oberbacke 14 und . Unterbacke 18 den eigentlichen Greiferkopf 19 schafft. Der Schwenkhebel 17 ist an der Stützvorrichtung 4 über eine Feder 20 angeschlossen, die bestrebt ist, den unteren Teil des Schwenkhebels 17 in die in Fig. 1 dargestellte nach hinten zwischen die beiden Stützstreben 5 gerichtete Stellung zu führen. Im unteren Bereich des Anbaugerätes 2 ist eine Anlage 21 für den unteren Teil des Fasses 1 vorgesehen.An upper jaw 14 is pivotally supported by the supporting device 4 and has a gripping nose 15 at its end facing away from the supporting device 4. The upper jaw 14 pivotally carries at 16 a pivot lever 17 which has a lower jaw 18, the interaction between the upper jaw 14 and. Lower jaw 18 creates the actual gripper head 19. The pivot lever 17 is connected to the support device 4 via a spring 20 which tends to guide the lower part of the pivot lever 17 into the position shown rearward in FIG. 1 between the two support struts 5. In the lower area of the attachment 2, a system 21 is provided for the lower part of the barrel 1.

Die Wirkungsweise der Einrichtung geht deutlicher aus der Darstellung in den Fig. 3 bis 5 hervor.The operation of the device is clearer from the illustration in FIGS. 3 to 5.

In Fig. 3 ist mittels der Hubeinrichtung das Anbaugerät 2 so an das Faß 1 herangefahren, daß die Unterbacke 18 unter den Faßreifen greift. In diesem Zustand ist noch die Oberbacke 14 hochgeschwenkt. Wird nunmehr das Anbaugerät 2 angehoben, kommt dadurch die Oberbacke 14 mit der Greifnase 15 hinter den oberen Bereich des Faßringes und legt dadurch das Faß 1 an dem eigentlichen Faßgreiferkopf 19 fest.In Fig. 3, the attachment 2 is moved to the barrel 1 by means of the lifting device so that the lower jaw 18 engages under the barrel tires. In this state, the upper jaw 14 is still pivoted up. If the attachment 2 is now raised, the upper jaw 14 thereby comes with the gripping nose 15 behind the upper area of the barrel ring and thereby sets the barrel 1 to the actual barrel gripper head 19.

Es ist erkennbar, daß die vorgeschlagene Einrichtung im Gegensatz zu den bisher bekannten Einrichtungen wesentlich einfacher ausgebildet ist, so daß dadurch weniger Verschleißerscheinungen auftreten können und Reparaturarbeiten leichter ausführbar sind und daß das ergriffene Faß sicher während des Transportes gehalten wird.It can be seen that the proposed device, in contrast to the previously known devices, is of considerably simpler design, so that fewer signs of wear can occur and repair work can be carried out more easily, and that the gripped barrel is held securely during transport.
