摘要：A robotic manipulator having a gripping tool assembly for separating a thinsheet of metal from a stack of metal sheets. The assembly comprises a frame mounted
to a lift arm. A separating device is pivotally mounted to the frame for grasping andlifting a corner of the top metal sheet to create an initial separation of the sheet fromthe stack. A plurality of stationary suction lifters are secured to the frame for graspingand lifting the remaining portions of the top sheet. The gripping tool assembly ischaracterized by first and second air hoses or nozzles mounted to the frame with thefirst air nozzle positioned above the second air nozzle whereby the first air nozzleprovides pressurized air toward the corner of the sheet to assist in the initial separationof the sheet and the second air nozzle provides pressurized air below the sheet after theinitial separation of the sheet from the stack. The subject invention also includes amethod comprising the steps of; affixing the stationary suction lifters and the separatingdevice to the top sheet, actuating the separating device to lift the corner of the sheet tocreate the initial separation between the sheet and the stack, and the method ischaracterized by dispensing pressurized air toward the corner of the top sheet
simultaneously with the actuating of the separating device and dispensing pressurized airbelow the top sheet after the initial separation of the sheet from the stack.
