Abstract
PURPOSE: To provide an automatic tester for the surface of a flat circular piece, by optically scanning the flaw, discoloration, bend, etc. of both the obverse and reverse sides of the flat circular piece and automatically sorting defective pieces on the basis of prescribed standards.
CONSTITUTION: Flat circular pieces 22 thrown into a hopper 3a are moved in a row on a conveyor 20 to a position setting rotary mechanism 4 in which the pieces are rotated and scanned. Light irradiated upon the surface of the piece 22 is reflected and introduced into a photoelectric scanner 30 so that the intensity of the reflected light corresponding to the flaw, discoloration, bend, etc. of the surface of the flat circular piece 22 is changed into an electric signal. This signal is supplied to an identification controller and compared with a prescribed reference signal level. Defective pieces are discharged by a removing mechanism 6 and stacked in a box 17. Proper pieces are inverted at 23 by an obverse-reverse inversion mechanism 7. The reverse side of the piece is automatically examined by all the same operation as the obverse side. The pieces finally regarded as proper are stacked in another box 19.
