Description

BACKGROUND OF THE INVENTION

[0001] The invention relates to a pharmaceutical automation system. More particularly, the present invention relates to a tablet cassette cabinet assembly for an automatic tablet dispensing and packaging system, which substantially increases tablet cassette capacity within a limited space reserved for the system while improving tablet cassette management efficiency.

[0002] An automatic tablet dispensing and packaging system is generally provided with a tablet packaging portion and a tablet dropping portion placed above the packaging portion. The tablet dropping portion includes a plurality of tablet cassettes containing different sets of tablets.

[0003] In order to increase capacity for housing the tablet cassettes, a flat type cabinet or a cylindrical type cabinet has been widely adopted to stack therein as many tablet cassettes as the system allows. Each tablet in the tablet cassettes comes to fall through a hole into the tablet packaging portion. So each hole inevitably holds on its wall either dusts or debris out of the dropping tablets. A tiny amount of tablet debris may result in medical care for a patient taking tablets packaged through the conventional tablet dispensing and packaging system.

[0004] A strong demand is to construct a system such that the hole for tablet passage can be easily cleaned or vacuumed while increasing system capacity of housing tablet cassettes.

SUMMARY OF THE INVENTION

[0005] Accordingly, it is an object of the present invention to provide an automatic tablet dispensing and packaging system that facilitates cleaning and vacuuming of tablet passages through which tablets are dropped in a tablet packaging unit.

[0006] Another object of the present invention is to substantially increase capacity of housing tablet cassettes in the system while facilitating management efficiency of the system.

[0007] To achieve the above-described objects, an automatic tablet dispensing and packaging system according to the present invention comprises a tablet packaging unit having an upper portion and a base cabinet having a front surface and side ends. The base cabinet is mounted on top of the upper portion of the tablet packaging unit.

[0008] The system also includes a first swing cabinet having a rear surface and side edges. A selected one of the side edges is swingably engaged to one of the side ends of the base cabinet so that the first swing cabinet becomes swingable to and from the front surface of the base cabinet, whereby the first swing cabinet is attached to and swiveled on the base cabinet to open when required. The system further includes a plurality of tablet cassettes each containing therein and dropping therefrom a predetermined number of tablets, wherein the tablet cassettes are detachably racked in said each cabinet in columns and rows.

[0009] For a better performance, the system includes a plurality of upright tablet passages attached to said each cabinet to communicate with the tablet cassettes in said each cabinet. The upright tablet passages are aligned with the tablet cassette columns to facilitate the tablet guidance from the tablet cassettes into the tablet packaging unit. When the first swing cabinet is swung open the upright tablet passages of the first swing cabinet are externally exposed to facilitate either cleaning or vacuuming of the tablet passages. The first swing cabinet is foldable so that the rear surface of the first swing cabinet can be overlapped to itself when folded.

[0010] For a better performance, there are provided first and second swing cabinets each defined by a front surface, a rear surface, an inner side end and an outer side end, wherein said each swing cabinet is linearly aligned such that the inner side ends of the swing cabinets approach each other, wherein one of the side ends of said each swing cabinet is swingably engaged to the base cabinet so that the first and second swing cabinets become swingable to and from the front surface of the base cabinet, whereby the first swing cabinet is attached to and swiveled on the base cabinet to open when required.

[0011] The advantages of the present invention are numerous in that: (1) the foldable mechanism of the tablet cassette cabinets enables a simultaneous vacuuming of each tablet passage in each cabinet by simply opening the swing cabinet from the base cabinet, wherein each tablet is dropped from each tablet cassette through the upright tablet passage into the tablet packaging unit; (2) a substantially increased number of tablet cassettes can be accommodated in the system according to the present invention without requiring additional installation space by providing the swiveling multiple cabinet mechanism; and (3) the swiveling cabinet system enables an additional cabinet installation with ease when required, thereby increasing tablet cassette capacity.
