<p>PROBLEM TO BE SOLVED: To identify individual workpiece to record a manufacturing condition, etc., even in a workpiece for changing its appearance in the manufacturing process for a continuous machining line. SOLUTION: In this system, an individual construction plate 1 can be identified with each other by each detection time, by detecting starting the carrying a construction plate 1 into a manufacturing process (n) by a photoelectric switch SW1, starting the carrying out the plate 1 from the process (n) by a photoelectric switch SW2, and starting carrying the plate 1 into the successive manufacturing processes by a photoelectric switch SW3.</p> |
