Abstract
The present invention features a pill-dispensing system which has a number of standardized, or universal-type, modules. Each module has a rotating, helix-drive mechanism, which is rotationally controlled by a microprocessor. The helical-drive mechanism features several improvements, both in the drive mechanism and in the software control of the rotational drive system by the microprocessor that allows for the dispensing of pills of all shapes and sizes one at a time. The helix of the drive is securely mounted within a rotatable, hollow tube. A stationary collar is mounted adjacent the upper end of the rotating tube. The rotating helix extends into the stationary collar and forces pills from the hollow tube to the dispensing edge of the stationary collar. A hopper positioned at the input end, or mouth of the tube, feeds a batch quantity of pills to the drive mechanism. The tube is angled upwardly from the mouth portion, so that the pill-dispensing end is positioned above the input end. In this fashion, the pills that are fed through the tube move upwardly against gravity.
