Collision protection device for two or three=dimensional gripper transfer units

摘要

The direct connection between one end of the support beam (15) and the corresponding cross slide (14) is formed as a hinged joint (17), and between the second end of the support beam and the corresponding slide as a pivot and slide joint (18). Each end of the support beam has a locking cylinder formed as a double acting pneumatic cylinder (3) which is always in a position for connection of the corresponding working cylinder (2) and is located at right angles to its direction of action, whose piston rod carries a catch bolt (4) that, in normal drive of the gripper transfer unit, corresponds to a catch bore (9).
