摘要： Method and system for stacking sheet metal parts that comprises providing a fixed frame with three positioning sensors and a movable frame comprising a vacuum gripper. Upon reception of a stack of sheet metal parts the method comprises gripping one sheet metal part, moving the movable frame in the Y-axis direction until the first and second positioning sensors detect the sheet metal part, calculating an angle "α" that corresponds to the rotation in Z-axis of the part and an overrun of the movable frame, rotating the movable frame the angle "α"; moving the movable frame in X-axis direction until the third positioning sensor detects the sheet metal part; calculating distances 'd1' and 'd2' as a difference between a predefined position for stacking the sheet metal parts and the current position of the metal sheet part; moving the movable frame the calculated distances 'd1' and 'd2' and depositing the part.

摘要： The present invention relates to a machine and a method for de-stacking metal sheets. The machine comprises a frame with suction cups that is adapted for picking up a metal sheet from a stack and a blower system arranged to blow air towards the edges of the metal sheets of the stack. An actuator is mounted with the frame and is adapted to exert a force on the metal sheet in a perpendicular direction relative to an upper surface of the metal sheet. A weight measuring device is adapted for measuring a load carried by the frame, so that when the measured weight is above the weight of a single metal sheet, the actuator is operated on the metal sheet and simultaneously air is blown towards the side surfaces of the metal sheet to separate said metal sheet from any other metal sheet attached thereto by cohesive forces from below.
