Abstract

A method for operating a vacuum gripping device including a suction gripper unit, which is provided with at least one suction gripper. The suction gripper unit can be connected, via a control valve device connected to it, selectively to a vacuum source or to a positive pressure source generating an ejector pulse in the suction gripper. The ejector pulse is generated as a function of the actual pressure established in the suction gripper unit after its connection to the positive pressure source. A vacuum gripping device suitable for executing this method and including a pressure measurement device for detecting the actual pressure and an electronic control unit used for controlling the control valve device and communicating with the pressure measurement device.
