Abstract
The present invention is related to a gripper having a stationary gripper member and a movably mounted gripper member being relatively movable toward said stationary gripper member. An actuating member extends through the stationary and the movable gripper members respectively. Cam surfaces are assigned to said pretensioned actuating member being contacted by contacting members causing the gripper members respectively to close upon removal of external forces.
Claims18
Gripper comprising:
- a stationary gripper member,
- a movable gripper member being relatively movable towards said stationary gripper member,
- a pretensioning means,
- a pretensioned actuating member contacting the stationary and the movable gripper members respectively,
- said pretensioned actuating member having cam surfaces being contacted by contacting members, said contacting members cause the gripper members respectively to close upon removal of external forces on said pretensioned actuating member.
Method for actuating a gripper between a closed position and an opened position comprising the steps of:
- moving a movable gripper member into at least one of a closed position and an open position with respect to a stationary gripper member, said step of moving further including at least one of a step of:
- contacting members contacting lower cam surface portions of an actuating means and surfaces of roller bodies of pushing and supporting means in a closed position, and
- contacting members contacting upper cam surface portions of an actuating means and surfaces of roller bodies of pushing and supporting means in an opened position.
