Abstract
PURPOSE: To detect rapidly a parts supply mechanism getting jammed by giving an alarm according to the output of a timer circuit that receives the output of a delay circuit connected to a parts upper-limit detection part.
CONSTITUTION: In case that parts drop part 2 is jammed with parts, parts upper- limit detection part 3 generates a signal continuously and delay circuit 6 also generates a continuous signal with delay of a certain time. Setting the time of parts operation by timer circuit 8 changes the output signal of parts feeder driving circuit 7 to "L" through AND circuit 9 after the set time of timer circuit 8. Consequently, parts feeder 1 is disabled to operate and parts feeder drop part 2 can therefore be prevented from overflowing due to parts jamming. Simultaneously, alarm tone circuit 10 is put into operation.
