Abstract:
The size of the gap separating first and second jaw members (26, 28) comprising a gripper arm is made adjustable by the provision of a translatable bracket (80) upon which an actuator (30) is supported. As the bracket (80) translates, so do the actuator (30) and a linkage (32) which connects a pivotable jaw member (28) to the actuator (30). Translation of the actuator (30) and linkage (32) changes the size of the gap separating the pivotable jaw member (28) and the other jaw member (26), thereby permitting the gripper arm to accommodate and engage articles of differing thicknesses.
