    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.

  • Patent number: 4919586
    Abstract: A mechanical closed loop robotic arm end effector positioning system which produces a precision reference frame with an associated workpiece fixture or other robotic manipulator system is disclosed. The positioning system results in decoupling of end effector operation from gross movement inaccuracies or vibrations of the robotic arm, thus allowing less precise robots to perform high precision tasks. The system includes a wrist assembly which is mountable to the robotic arm near the arm's distal functional end. The wrist assembly has a compliant member and a first positioning member connected thereto. The first positioning member includes a first docking arrangement. A second positioning member associated with the workpiece fixture includes a second docking arrangement. The first and second docking arrangements are sized and positioned to engageably mate within the robotic arm's resolution when the robotic arm attains a target position relative to the workpiece fixture.

  • Patent number: 4911605
    Abstract: A drum clamping unit for plastics material drums with peripheral "L'8 chime rings below the drum head is adapted to be mounted on suitable lifting and transporting devices such as lift trucks, overhead cranes, and the like to automatically engage, latch onto, and discharge one or more of the molded plastics material drums without damaging the drums. The unit has a plurality of clamping jaws automatically triggered to clamping positions by the drum heads as the unit is lowered alongside the drums. These clamping jaws are positioned to engage only with the bottom and inner face of the "L" chime ring of each drum and remain clear of the drum head and drum periphery thereby avoiding any damage to the drums especially as they are raised to clamp onto the "L" rings. Then, when the raised clamped drums are conveyed to and lowered on a desired location, the jaws are released, retracted automatically and held in a retracted position until the unit is again lowered to engage a drum head in a subsequent operation.
