Automated precision small object counting and dispensing system and method
Abstract:
A small object dispenser adapted to receive a canister of objects such as pills, the canister being coupled atop it through a secure, bar-code matched gate operated by a central controller. A hopper below the gate directs smaller quantities of objects into a charge block adapted to measure out a select number of objects into an angularly disposed, circular counter where they accumulate atop a movable plate forming the bottom of the counter. The plate bears slots around its perimeter adjacent the cylindrical walls of the counter. As the central controller operates a servo motor to rotate the plate in measured increments, it urges a precise count of objects from the bottom of the counter to a port through which they fall one at a time into a receptacle such as a prescription bottle. Orientation means on the interior of the walls orient objects so that only a single object may fall into each slot, thereby preventing overfilling. A separate sensor counts the objects as they fall to verify quantity and guard against underfilling due to empty slots.
