ABSTRACT:
An apparatus (10) for automatically feeding and measuring circular discs (12) includes a gauging station (15). The latter includes a pair of opposed capacitive displacement measuring probes (27 and 28). The probes are connected to a thickness measuring test set (66), adapted to provide a capacitance-derived measurement of the thickness of each advancing disc (12) at either one or a plurality of spaced measurement points (142) extending across the major surfaces thereof. Precise control must be maintained over the speed at which each disc is passed between the capacitive probes (27, 28) in a non-contacting manner. This is accomplished through the use of a controllably driven drive wheel (98), and a cooperative arcuate feed channel section (74), which includes an outer arcuate sidewall ramp insert (92). The drive wheel is formed with a resilient peripheral surface for initially frictionally engaging the periphery of each disc (12), when gravity-fed thereto and, thereafter, biasing the disc against, and driving it rotatably along, the inner wall of the ramp insert (92) at a precisely controlled speed. An adjustable disc-sensing assembly (125), which includes a rotatable platform (32) and a spaced pair of photodetectors (127 and 128) mounted thereon, edge portions of each disc (12) while advanced between the probes (27 and 28) and, thereby, control the START-STOP limits for each measurement period.
