Abstract

PROBLEM TO BE SOLVED: To supply a workpiece efficiently by simple configuration in an automatic assembly process by providing a transfer machine which can move a clamp part which can hold a workpiece by aligning the clamp part in parallel with inclination angle of the clamp part and a turning plate. SOLUTION: First, when a workpiece 17 in a frame 15 put on a turning plate 7 is taken out automatically, a knock pin 3 of a coming-in-and-out member 4 rises, passes through a through hole 14 of a conveyance plate 12, hits against a slide-stop block 8, and tilts the turning plate 7 centered on a rotary shaft 9. The inclination angle is determined to be a fixed angle based on rise amount of an air cylinder 2 on which the knock pin 3 is attached and such angle that workpieces 17 in the frame 15 are arranged in order in a fixed direction in a division part 16 due to their self-weight, respectively. The workpieces 17 arranged in order in the fixed direction at inclination are taken out sequentially by a chuck 19 of a clamp part 20 of a transfer machine 22 attached in parallel with the inclination angle and are moved as shown by dotted line to supply them to a next process.
