Patent number: 6474711Abstract: The invention provides a grapple device and a method for manipulating, i.e., grabbing, holding and releasing objects. The grapple comprises two parallel rollers with gripping surfaces, where the rollers are pushed towards each other with sufficient force to hold a graspable portion of a deformable object. When the grapple comes onto contact with any portion of the deformable object, a signal activates a set of gears causing the rollers to rotate in opposing directions so that a graspable portion of the object is dragged between the rollers. When sufficient material is caught between the rollers, a signal activates a brake automatically stopping the rotation of the rollers, whereby the rollers then hold the graspable portion of the object allowing the object to be moved to a desired location. When the object is properly located, a signal is generated which causes the rollers to rotate in the opposite direction to release the object.Type: GrantFiled: June 7, 2001Date of Patent: November 5, 2002Inventors: Homayoon Kazerooni, Christopher Jude Foley

Patent number: 5098254Abstract: A robotic palletizer including a vertical column, a telescoping horizontal arm mounted for vertical movement along the column and a hand assembly mounted at the end of the horizontal arm. A pair of photodetectors, movable with the hand assembly, sense the presence and location of cartons in place on a pallet being loaded and signal the palletizer when the vertical height and horizontal extension of the hand assembly are sufficient to place cartons in the proper position for loading onto the pallet. A circuit controls operation of the palletizer in accordance with the sizes and shapes of the cartons and pallets and permits limited variation of the loading pattern provided by the palletizer. Separate conveyors transport cartons to the palletizer for loading and remove loaded pallets from the palletizer upon completion of the loading cycle.Type: GrantFiled: September 12, 1988Date of Patent: March 24, 1992Assignee: FMC CorporationInventors: Kenneth F.
