Abstract

The present invention relates to a suction cup device for engaging, displacing and releasing objects of substantially unequal sizes, such as food products, in particular eggs or fruit, comprising a bellows, consisting of elastic material, an air suction duct, the bellows being provided at one end with a collar with which a bellows is connected to the air suction duct, and, at the end remote therefrom, with a mouth-shaped opening for successively approaching, applying suction to and thereby gripping, displacing and placing and, finally, releasing such an object in an approach direction or release direction, respectively, the bellows being compressible over at least a small distance in substantially the approach direction or placement direction, and a frame, connected to the at least one air suction duct, with supply and discharge means for air, and connected to displacement means which, dug engagement, position the frame over the objects such that each mouth-shaped opening in its entirety is positioned onto such an object, in particular that such an air suction duct is movable relative to the frame in the approach or placement direction, such that during engagement and release, the air suction duct is only moved in the direction opposite to the approach direction or placement direction if the bellows is compressed over said small distance. Further, locking means serve for locking the air suction duct after engagement or placement of the objects, and for releasing the air suction duct upon release of the objects. In this manner, it is in particular effected that objects of unequal sizes, after engagement, are all suspended with their bottom end at approximately the same height and, during release, are not compressed, so that damages during pick-up and release are avoided.
