Gripper device for gripping objects

摘要

The device (11) has three gripping units (17a-17c) that are moved by a working movement between a release position and an object cross-gripping position. The gripping units are grouped to a gripping center such that three work planes (46a-46c) of gripping elements (22a-22c) are provided angularly and radially with respect to gripping center or offset in parallel to each other. An adjustable drive device is associated with adjusting drive to move work planes by an actuator by displacement between radial direction and parallel to each other staggered orientation.
