Abstract
A gripper for containers, in particular for bottles, with at least first and second gripper arms (1, 2) which are mounted such that they can pivot and are acted on in the gripping pivoting direction by magnetically interacting permanent magnets, such as permanent magnets which simultaneously repel one another and attract one another are arranged in such a way that the sum of the repelling and attracting forces which act in the gripping pivoting direction on the gripper arms is substantially constant within a predetermined gripping range (d1 to d2) of the gripper which covers different container gripping sizes.
Claims26
Gripping Device (G) for containers (B), in particular for bottles in container transport systems or container handling systems, comprising at least two relative to each other movable gripper arms (1, 2), the gripper arms (1, 2) being impinged in gripper direction by magnetically cooperating permanent magnets (P1, P2, P3, P4), the permanent magnets simultaneously repelling and attracting each other, the permanent magnets being designed in such manner and arranged movably relative to each other by the working motion of the gripping device (G) that the sum is essentially constant of the repulsive and attractive forces acting in grip direction on the gripper arms (1, 2) within a pre-determined grip range (d1 to d2) covering various container grip sizes.
Gripping Device according to claim 19, wherein the disc diameter of the second permanent magnets (P2′) is one of smaller or larger than that of the first and third permanent magnet (P1, P3).
