Area vacuum gripper operated with pressurised air

摘要

The gripper (10) has a suction chamber (16) including a suction wall (18) i.e. perforated steel plate, with perforations, where the chamber is placed on a workpiece (12). An ejector nozzle (28) is connected to the chamber. An outlet (40) of the nozzle is opened to an outside or into an exhaust air duct. A suction inlet (38) of the nozzle is emptied into the chamber. An outlet opening (26) of the chamber is coaxially arranged at the inlet. The inlet is formed by an opening of a sleeve-like section of the nozzle. A front side of the section is arranged at a distance to a surface of the chamber.
