Abstract

Devices, systems, and methods for automatic pill dispensing are disclosed herein. An exemplary automatic pill dispensing device includes a temporary storage compartment, a feeding assembly, a dispensing route, a plurality of optical sensors, and a controller. The temporary storage compartment stores pills that are to be counted and eventually dispensed into a pill bottle. The feeding assembly is coupled to the temporary storage compartment and can move or stop the flow of pills into the dispensing route where the plurality of optical sensors count the pills as they pass by the light beams thereof. The controller receives a count from the plurality of optical sensors and stops the feeding assembly when a predetermined count of pills has been reached.

Systems and methods utilizing the pill dispensing devices include incorporating a centralized computer and a conveyor belt system to accurately and efficiently dispense a plurality of pill types into pill bottles.
