ABSTRACT:
A dispensing apparatus for selectively dispensing articles from an inner cavity of a bin. The apparatus includes a pick-up head having a plurality of spaced suction cups which is moveably supported by a positioning assembly. The positioning assembly locates the pick-up head at various positions relative to the inner cavity of the bin to retrieve randomly organized articles within the bin. The dispensing apparatus includes a vacuum control assembly which is coupled to a vacuum source for selectively applying a suction pressure to the suction cups of the pick-up head. The suction pressure attracts the articles stored in the bin towards the suction cups to retrieve an article from the bin to be dispensed. A sensing assembly is coupled to each of the suction cups to determine whether an article is attached to the suction cup. The vacuum control assembly is coupled to the sensing assembly to selectively apply and release suction pressure to the suction cups. When the sensing assembly senses at least one suction cup having an article attached thereto, the vacuum control assembly releases pressure to all but one designated suction cup having an article attached thereto to dispense a single article.
