Abstract
A transfer apparatus for automated parts movement includes a cylinder and a piston assembly slidably positioned within the cylinder. The piston assembly includes an outer piston having a recess in which an inner piston is slidably received. A transfer assembly is attached to the piston assembly and includes an inner rod, a sheath, and a gripper. Introduction of fluid at one port or end of the cylinder moves the piston assembly to extend the gripper and transport a gripped part to a target destination. At the target destination, the transfer assembly is moved via pressurized fluid in the cylinder to cause the gripper to release the gripped part. Introduction of fluid generally at an opposite end of the cylinder moves the transfer assembly and gripper to a retracted position relative to the cylinder.
Claims7
An apparatus for automated parts movement comprising:
- an enclosed cylinder having a first end and an opposing second end, and an interior, said enclosed cylinder including first and second fluid ports for selectively providing fluid pressure at opposite ends of said interior of said enclosed cylinder;
- a piston assembly slidably positioned within said interior of said enclosed cylinder, said piston assembly comprising first and second pistons;
- a transfer assembly coupled to said piston assembly and movable relative to said enclosed cylinder, said transfer assembly having a first portion coupled to said first piston and a second portion coupled to said second piston;
- a gripper coupled to said transfer assembly, said gripper being adapted to grip a part;
- and
- wherein movement of said piston assembly within said enclosed cylinder in response to fluid pressure within said enclosed cylinder via introduction of fluid at at least one of said first and second fluid ports (i) moves said transfer assembly and said gripper relative to said enclosed cylinder in a first direction to an extended position relative to said enclosed cylinder, (ii) moves said first portion of said transfer assembly relative to said second portion of said transfer assembly to cause said gripper to release a gripped part, and (iii) moves said transfer assembly and said gripper in a second direction to a retracted position, said second direction being generally opposite said first direction.
