Abstract (en)
[origin: EP0439120A2] In known transfer devices, a linear driving movement for the gripper fingers has superimposed on it a swivelling movement of the gripper fingers, thereby making it possible to achieve a path of movement of the free ends of the gripper fingers which brings about a relatively rapid and wide opening of the gripper fingers and a corresponding withdrawal of the gripper from the tool concerned. The disadvantage here is the rigidly predetermined motional sequence of the gripper fingers. In order to achieve a motional sequence of the gripper fingers which is optimum for the individual requirements, the movement of the gripper fingers is controlled by cam tracks matched to the individual requirements and having track detectors. <IMAGE>
