  • Patent number: 8943951
    Abstract: A vacuum—actuated handling device including, in the inner space (12) of a hollow body (11) with closed ends, a guide cylinder (13) defining an axial chamber (26) and, with the inner space, an annular compartment (25). In the chamber (26) a piston (14) movable between a rearward position adjacent to a first end and a forward position adjacent to a second end of said body (11) is accommodated. The piston is provided with an axially pierced rod (15), emerging from the second end of the body, carrying a gripping end sucker (27) and it is connected to a return spring (23) aiming to move the piston (14) to the rearward position. The piston (14) divides the chamber (26) in a first part of the chamber (a) adjacent to the first end and a second part of the chamber (b) on the side of said piston rod (15).

  • Patent number: 7452017
    Abstract: This invention relates to a pneumatically controlled finger gripper that has a supporting body (111) forming a chamber. A fixed axial rod (119) is secured to a proximal part of the body, extending in the chamber and emerging from a distal part of the body. A compression disk (113) is connected to the fixed rod. A pneumatic control piston (112) is guided along the axial rod and moves in the chamber (115) with respect to the compression disk (113) between an inactive position, at a distance from the compression disk, and a forward active position, near the compression disk. A flexible gripper element (114) is mounted between the compression disk (113) and control piston (112). The flexible gripper element moves between a contracted position and an expanded position in response to the movements ofthe control piston between the inactive and active positions of the compression disk.
