BACKGROUND OF THE INVENTION

The invention relates to a pharmaceutical automation system for sorting and packaging tablets. More particularly, the present invention relates to a tablet supplying and packaging apparatus that optimally combines a cassette-based tablet supply system and a turntable-based tablet supply system to substantially improve pharmaceutical efficiency.

A doctor's prescription generally requires one or more kinds of tablets for a type of disease. So the more types of illnesses included in a prescription, the more kinds of different tablets a patient should take for each dosage. The dosage may vary from once per day to three or more times per day depending on seriousness and types of disease, or how many different types of illnesses a patient suffers.

The cassette-based tablet supply system has difficulty in automation favoring extra pills such as half-split pills and quarter-split pills. That is, such split pills have disadvantageously stayed away from pharmaceutical automation. The alternative was a turntable-based tablet supply system that adopts manual tablet sorting and automatic tablet packaging mechanism. However, the turntable-based system has limitations due to relatively small capacity.

Accordingly, there has been a strong demand for an optimal combination of the cassette-based tablet supply system and the turntable-based system.

The controller controls an operation of the apparatus. The cassette unit is defined by a width and a height and has a cassette rack and a plurality of tablet cassettes detachably mounted on the cassette rack in columns and rows. The tablet cassettes each release a predetermined amount of tablets therefrom in accordance with the controller.

The turntable has a center and a plurality of tablet containers disposed around the center. Each tablet container is defined by side walls, a top opening and a bottom opening. Preferably, the turntable is disposed lower in level than a lowermost row of the tablet cassettes and in front of the cassette unit so that one or more tablets manually distributed in at least one of said tablet containers are downwardly released in accordance with the controller.

The packaging unit is disposed below the cassette unit and the turntable for packaging the tablets selectively released from the tablet cassettes and tablet containers into a plurality of tablet paper bags in accordance with the controller.

For a better performance, the apparatus further comprises a hopper disposed between the packaging unit and both of the turntable and the lowermost cassette row of the tablet cassettes to guide the tablets from the turntable and the tablet cassettes to the packaging unit.

The controller comprises a monitor screen to input a prescription information and display the operation of the apparatus a prescription processing, and a processor to administer a tablet release of the tablet cassettes and the turntable, and a tablet packaging and external discharge of the packaging unit, in accordance with the prescription information input through the monitor screen.
