Automatic unit for mounting washers over bolts - has bolts to be positioned at outlet returned to inlet if no washer is sensed

摘要

The arrangement consists of a transport wheel which has a number of cut-outs along its circumference in each of which a bolt is mounted. A feed-in chute with washers reaches to near the wheel and a washer mounting arrangement. A feeler is mounted next to the infeed chute which operates a deflection when the feeler detects a bolt on which no washer is mounted. The deflector can be placed in two positions. In one position the bolts are free to be placed on an outlet rail.
