Abstract

A device for lifting a parcel (7), consists of a suction head (1) which is attached to the lower end of a flexible bellows (4). The parcel is gripped by the suction head and is then raised by evacuating the bellows. The suction head is pressed downwards against the parcel by expanding the bellows by means of compressed air. Instead of evacuating the bellows, the load may be lifted by means of a cable (8), which is attached to the suction head and then passes upwards through the bellows and around a guide pulley mounted on the bellows support (5). USE/ADVANTAGE - Lifting of parcels from shelves and similar places with restricted headroom.

Description

Die Erfindung beschreibt eine Vorrichtung zum Herausnehmen von Packstücken aus Lagerkisten in Regalen oder Regalfächern. In die­ sen Fällen ist der Freiraum über den zu entnehmenden Teilen klein zu halten, um Lagervolumen hoch zu nutzen. Die Entnahme gelingt z. B. mit einem waagerecht angeordneten Roboterarm, dessen Handge­ lenk einen Greifer auf die zu entnehmenden Teile absenkt. Um eine senkrechte Bewegung ausführen zu können, muß der Arm und das Ab­ knicken des Handgelenkes simultan und in Abhängigkeit voneinander bewegt werden. Dieser Vorgang kann bei getrennt gesteuerten Achsen nicht beliebig schnell ablaufen, da ansonsten ein Versatz des Greifers entstehen würde.The invention describes a device for removing Packages from storage boxes on shelves or shelves. In the In these cases, the free space above the parts to be removed is small to keep in order to use the storage volume high. The removal succeeds e.g. B. with a horizontally arranged robot arm, the hand steer a gripper onto the parts to be removed. To one To be able to perform vertical movement, the arm and the Ab buckling of the wrist simultaneously and depending on each other be moved. This can be done with separately controlled axes do not run as quickly as otherwise an offset of the Gripper would arise.

Eine Lösung dieses Problems stellt die Erfindung dar. Der Greifer wird senkrecht mittels Balg abgesenkt. Die Abwärtsbewegung erfolgt durch Druckluft oder ein anderes Medium, das in den Balg eingelei­ tet wird. In der Situation A befindet sich der Greifer, z. B. Sau­ ger 1, auf dem anzuhebenden Packstück 7. Die Druckluft wird über den Stutzen 6 in den Balg 4 eingeleitet. Das Ansaugen des Teils 7 erfolgt über die Vakuumleitung 8. Das Anheben erfolgt mittels Um­ schalten von Druck auf Vakuum am Stutzen 6. Die Distanzringe 3 verhindern das Zusammenziehen des Balgs. Ohne diese Distanzringe 3 kann das Hochziehen mittels Seil 2 erfolgen, das vakuumdicht aus dem Arm 5 geführt wird. Die Situation B zeigt den angehobenen Zu­ stand.The invention represents a solution to this problem. The gripper is lowered vertically by means of a bellows. The downward movement is carried out by compressed air or another medium that is introduced into the bellows. In situation A there is the gripper, e.g. B. Sau ger 1 , on the package to be lifted 7th The compressed air is introduced into the bellows 4 via the nozzle 6 . Part 7 is sucked in via vacuum line 8 . The lifting takes place by switching from pressure to vacuum at the nozzle 6 . The spacer rings 3 prevent the bellows from contracting. Without these spacer rings 3 , pulling up can be carried out by means of rope 2 , which is guided out of arm 5 in a vacuum-tight manner. Situation B shows the raised state.
