Abstract
A production line has a plurality of processing stations which includes both manual and automatic processing stations. A workpiece conveying system combined with the production line has a base, a pair of side plates mounted on the base, a plurality of spaced roller shafts rotatably supported on the side plates, a plurality of rollers mounted on the roller shafts for conveying workpieces thereon, and a drive mechanism for rotating the roller shafts to rotate the rollers. In the manual processing station, the rollers are rigidly fixed to the roller shafts for conveying workpieces at fixed intervals. In the automatic processing station, the rollers are held in frictionally rotatable engagement with the roller shafts for rotation in unison with the roller shafts. When resistive forces greater than a given level are applied to the rollers, the roller shafts rotate idly thereby adjusting intervals between workpieces in the automatic processing station.
