<p>This invention aims to achieve a two-sided clamp for manipulating heads of paper rolls. The clamp comprises an arm (14) having its one end attached to the wrist joint of a robot and the other end carrying two grasping means (11, 12) which are aligned parallel and outward facing to opposite directions. Each of the grasping means (11, 12) comprises a base plate and multiple resilient suction cups (13) which are mounted to the base plate. The grasping means (11, 12) are mounted to the arm (14) so that the clamping center point T1 of the first grasping means (12) is farther removed from the wrist joint (19) of the robot (2) in the direction of the longitudinal axis of the arm (14) than the clamping center point T2 of the second suction member (11). The grasping means (11, 12) are mounted in an asymmetrical manner to the arm (14). The asymmetrical structure of the clamp facilitates the two-sided structure of the clamp. <IMAGE></p> |
