Gripping element of robot arm holding object with suction cup, comprising control valve initiating two individual functions

摘要

A control valve (11) is accommodated inside the gripping element (2) using the suction forces for two different, successively performed actions. A cylinder and piston unit (6, 7, 8) is connected with a suction unit (4, 5). When the valve (11) is switched into a first position the suction element (4) is moved by the suction forces towards the object to be held and lifted. The spring supported suction cup (4), attaching itself to the object, is activated when the valve (11) is switched into a second position.
