Abstract:

An improvement to carousel-type component dispensers which eliminates the requirement of operator intervention in order to access the next component required in the assembly of a work piece. Each time the operator inserts his hand in the dispenser to remove a component, he interrupts a light beam which triggers the dispenser's indexing mechanism to position itself for the next position of rotation. When the operator removes the component, the light beam path is restored and a light activated detector signals the dispenser's rotation mechanism to rotate the dispenser to the position specified by the indexing mechanism. The apparatus includes time delay circuitry which prevents the carousel from rotating while the operator's hand is in the carousel accessing a component.
