Abstract
A vacuum-type gripping apparatus includes a frame which is movable between a retracted position, in which the frame is remote from an item stored in a storage bin, and an extended position, in which the frame is proximate to an item stored in the storage bin. The apparatus includes a vacuum-type gripping mechanism which grips the item to be extracted from the storage bin prior to and during the extraction operation. The vacuum-type gripping mechanism employs a redundant vacuum source which improves the operating reliability of the apparatus. A lifting mechanism, which is adapted to engage a bottom surface of the item to be extracted, cooperates with the vacuum-type gripping mechanism during the extraction operation.
