Claims

[Scope of utility model registration request]

- A workpiece transfer device equipped with fingers that can be opened and closed, raised and lowered, and rotated horizontally in order to transfer a workpiece gripped at a position to another nearby position with a height difference,
A two-stage reciprocating actuator consisting of two cylinders stacked coaxially, a cylindrical guide attached to the top of the actuator and having a cam groove for turning guide on the side surface, and a cylindrical guide that is inserted concentrically into the guide cylinder and the cam. a hollow piston rod having a guide pin guided by the shaft, one end of which is connected to the piston of the first cylinder of the two cylinders, and the other end of which has a finger support plate; an opening/closing transmission mechanism that is attached to the tip of the piston rod of the second cylinder of the cylinders and converts vertical motion into horizontal motion via a spherical sliding bearing, the finger being pivotally supported on a support plate and opening/closing operation end A workpiece transfer device characterized in that it is connected to the opening/closing transmission mechanism at a side thereof.
