Filed: 2000-03-07
Abstract: PROBLEM TO BE SOLVED: To reduce tact time for taking up a single workpiece, cost and complaint from users, to expand allowable board thickness, reduce in size, and to save energy. SOLUTION: When a top workpiece on loaded plate shaped workpieces is suspended by a workpiece suction device to be fed to a plate working machine, a laser beam outputted from an optical detecting device 29 is projected to the suspended workpiece while moving to a plate thickness direction at a constant speed, and a time for receiving a reflected light is measured by a clock 41. A thickness of the workpiece is calculated by a calculator 47 from the measured time for receiving the reflected light and a calibration constant obtained in advance by calculating a time for receiving a reflected light from the optical detecting device 29 to a standard thickness of a master gauge. A comparison determination device 49 compares whether the calculated thickness is within a predetermined tolerance or not and determines whether the suspended workpiece is taken up in single or not.
