Beschreibung description
Gegenstand vorliegender Erfindung ist eine Greifervorrichtung für zu hebende Lasten, wie Harassen oder Fässer, welche in Verbindung mit einem Vaku-um-Hebegerät, wie z.B. im Patent CH 656 599 dargestellt, eingesetzt wird. The present invention relates to a gripper device for loads to be lifted, such as harasses or barrels, which in connection with a vacuum lifting device, such as e.g. shown in patent CH 656 599, is used.
Das Palettieren und Entpalettieren von Papier-und Kunststoffsäcken und von Kartons ist mit den Vakuum-Hebegeräten eine rationelle und einfache Sache. Palletizing and depalletizing paper and plastic sacks and cardboard boxes is a rational and simple task with the vacuum lifting devices.
Für das Heben von Behältern, die oben offen sind, z.B. Harassen, sind längs- oder stirnseitige mechanische Klemmvorrichtungen, wie Scherenzangen oder Greiferzangen bekannt. Der Hauptnachteil dieser Systeme liegt in der grossen Bauhöhe und in der mechanischen Verriegelung und Entriegelung der Scherenzange. For lifting containers that are open at the top, e.g. Harasses, longitudinal or end mechanical clamping devices, such as scissor tongs or gripper tongs, are known. The main disadvantage of these systems is the large height and the mechanical locking and unlocking of the scissor tongs.
Aufgabe vorliegender Erfindung ist, die oben genannten Nachteile zu eliminieren, ohne eine zusätzliche fremde Betätigungskraft, wie z.B. Elektrizität, für die Klemmkraft zu Hilfe zu nehmen. The object of the present invention is to eliminate the disadvantages mentioned above without an additional external actuating force, e.g. Electricity to use for the clamping force.
Die Lösung dieser Aufgabe ist erfindungsgemäss in den Patentansprüchen 1 bis 4 definiert und in den folgenden Zeichnungen beispielsweise dargestellt: The solution to this problem is defined according to the invention in claims 1 to 4 and shown in the following drawings, for example:
Fig. 1 zeigt eine Seitenansicht der Greifer-Vor-richtung mit 2 Vakuum-Bälgen, verbunden mit dem Vakuum-Hebegerät. Fig. 1 shows a side view of the gripper device with 2 vacuum bellows, connected to the vacuum lifting device.
Fig. 2 zeigt die Greifer-Vorrichtung von oben. Fig. 2 shows the gripper device from above.
Fig. 3 zeigt die Greifer-Vorrichtung von oben, mit Seilzug, gemäss Anspruch 3. Fig. 3 shows the gripper device from above, with a cable, according to claim 3.
Fig. 4 zeigt die Greifer-Vorrichtung mit schwenkbaren Haltern und auswechselbaren, Greifelementen, sowie die als Saugteller ausgebildeten Greifelemente. Fig. 4 shows the gripper device with pivotable holders and interchangeable gripping elements, as well as the gripping elements designed as suction plates.
Das hier halbschematisch dargestellte Vakuum-Hebegerät 1 wird mit dem linken Tragrahmen 5 verschraubt, oder mit Schneilverschlüssen verbunden. Die Druckfeder 11 stösst die Seiten-Tragrahmen 5 und 6 bis zu dem hier nicht aufgezeigten Anschlag auseinander. Die Vakuum-Bälge 2 sind einerseits über einen Träger mit dem Tragrahmen fest verbunden, anderseits sind sie über die Zugstangen 8 mit dem Tragrahmen 6 fest verbunden. The vacuum lifting device 1 shown here semi-schematically is screwed to the left support frame 5 or connected with quick-release fasteners. The compression spring 11 pushes the side support frames 5 and 6 apart up to the stop not shown here. The vacuum bellows 2 are, on the one hand, firmly connected to the supporting frame via a carrier, and, on the other hand, they are firmly connected to the supporting frame 6 via the tie rods 8.
Die Grundfläche beider Vakuum-Bälge 2 ist um einiges grösser als die Grundfläche des Hubschlauches 12 des Vakuum-Hebegerätes 1, damit das Festklemmen der Last 3 erfolgen kann, bevor die Last 3 sich abhebt. The base area of both vacuum bellows 2 is somewhat larger than the base area of the lifting hose 12 of the vacuum lifting device 1, so that the load 3 can be clamped before the load 3 lifts off.
Die Vakuum-Bälge 2 sind über einen Steuerschieber oder einen Kugelhahn 4 in Zweiweg-Aus-führung, einerseits mit dem Hubschlauch 12 des Vakuum-Hebegerätes 1 verbunden, oder sie sind anderseits mit der Aussenluft in Verbindung. The vacuum bellows 2 are connected via a control slide or a ball valve 4 in a two-way design, on the one hand to the lifting hose 12 of the vacuum lifting device 1, or on the other hand they are connected to the outside air.
Die in Anspruch 3 und Fig. 3 dargestellte Variante unterscheidet sich dadurch von der vorgängig beschriebenen Ausführung, dass die Vakuum-Bälge 2 mit je einem Zugseil über je einer am Querrohr des Tragrahmens 6 befestigten Umlenkrolle mit dem Tragrahmen 5 verbunden sind. Dadurch ergibt sich eine Übersetzung der Klemmkraft im Verhältnis 1 zu 2. The variant shown in claim 3 and Fig. 3 differs from the previously described embodiment in that the vacuum bellows 2 are each connected to the supporting frame 5 with a pull rope via a respective deflection pulley attached to the cross tube of the supporting frame 6. This results in a translation of the clamping force in a ratio of 1 to 2.
In Fig. 4 ist weiter die Greifer-Vorrichtung nach Anspruch 1 dargestellt, jedoch ausgerüstet mit einer Schwenkvorrichtung 15 und 16, mit einfachen, auswechselbaren Greifelementen 17, welche die Last festklemmen. In Fig. 4 the gripper device is further shown according to claim 1, but equipped with a pivoting device 15 and 16, with simple, interchangeable gripping elements 17 which clamp the load.
Auch eine weitere Variante nach Anspruch 1 ist in Fig. 4 ersichtlich, wonach die Greifelemente 17, durch Vakuum unterstützte Saugteller 18, ersetzt sind, welche die Last zusätzlich festsaugen. Diese letzte Version bietet höhere Sicherheit für die Bedienperson, insbesondere beim Heben und Entleeren von Fässern. A further variant according to claim 1 can also be seen in FIG. 4, according to which the gripping elements 17, replaced by vacuum-assisted suction plates 18, which additionally suck the load in place. This last version offers greater safety for the operator, especially when lifting and emptying drums.
