Abstract
A proposal is made for a changing system for the gripper jaws (3, 3') of handling machines, in particular assembly robots, comprising a gripper head (1), having at least two exchangeable gripper jaws (3, 3') in order to rapidly exchange gripper jaws so that at least one fixing element (bolt 7) is provided between an exchange layer and a clamping layer, said fixing element interacting with an allocated gripper jaw (3, 3') having an adpated fixing shape, and moreover the gripper head (1) and the gripper jaws (3, 3') have at least one mutually fitting recess (21, 22) or a projecting element (23, 5) for the reproducible, precise positioning of the connection between gripper head (1) and gripper jaws (3, 3'), and furthermore each gripper jaw (3, 3') has at least one further fixing shape (24) and/or a further recess (22) which can interact with the correspondingly allocated fitting projecting elements (12) and/or fitting recesses (25) of a magazine (11), whereby the magazine (11) has several fitting projecting elements (12) and/or fitting recesses (25) for the provision of different gripper jaws (3, 3').
