ABSTRACT:
The output of a high speed press or bindery is formed into stacks which are then combined into four stack "cubes". The cubes are handled as units and formed into tiers which can be loaded onto pallets. A pickup head for manipulating the cubes is carried by a transport device such as a gantry or robot arm. It has a top plate which is connected to the transport device. The top plate carries horizontal guide members from which depend four side panels. The side panels may be retracted to grasp the sides of the cube or extended to release the cube. Fingers mounted along the bottom edges of the side panels are designed to extend between the bottom sheets of the cube and the surface on which it sits. They can be locked into this position, permitting the cube to be lifted and transported by the pickup head. Also disclosed is a gantry-type transport device with a telescoping extender to which the pickup head is connected.
