Abstract
An apparatus for controlled dispensing of a plurality of objects, the apparatus comprising a housing and frame assembly, a track assembly comprising a pair of parallel spaced apart tracks shaped in a convoluted closed loop shape to optimize space and volume, and a plurality of tubes disposed within the track assembly and able to move within the tracks. A dispensing assembly has a pneumatic ram for ejecting an object placed in the tube, and an indexing assembly for advancing the tube after ejection of its object. A ratchet assembly permits one directional movement of the tubes and prevents tubes from moving backward to the dispensing assembly. At least one assist advancing assembly has a pneumatic ram for pushing the tubes within the track in one direction. Photosensors used in conjunction with a microprocessor controller enable the apparatus to detect low object load, speed and system error. A user display provides for control of the apparatus.
