Abstract

A drug storing apparatus for an automatic drug dispensing machine includes a frame provided with a multiplicity of inclined supports arranged one on top of the other or in rows for supporting a multiplicity of drug cases, and the supports may also be configured into rails. The drug cases are detachably connected to a multiplicity of drive boxes which may be mounted onto the frame along the inclined rails. The drug cases are arranged in such a manner that their outlets are oriented towards a central portion of a hopper. Each drive box is also provided with guide rails and contains therein a motor which has an axle oriented towards its corresponding drug case. When a drug case slides along the guide rails to fit onto its corresponding drive box, a coupling of a feeding element of the drug case just fits onto the axle of the motor. A computer control center controls the rotation of the motor axles of the drug cases so that the feeding elements thereof may feed predetermined kinds and number of drugs into the central portion of the hopper.

Claims

1. A drug storing apparatus for use in an automatic drug dispensing machine, comprising a frame for supporting a multiplicity of drug cases, each of said drug cases having an outlet and a feeding element disposed near said outlet for automatically feeding a fixed number of drugs, so that tablets or pills stored in each of said drug cases may, according to a command from a computer control center, be individually discharged via said outlet into a hopper located below a lower portion of said frame to be ready for packing, wherein

said frame has a multiplicity of inclined rails oriented towards a same direction;

each of said drug cases has an inner end and an outer end, said outer end being disposed at a position higher than that of said inner end with an inclined plate connecting one bottom edge of said outer end and a bottom edge of said inner end, said inner end being provided with said outlet and said feeding element; and

a multiplicity of drive elements each having a drive box slidable along said inclined rails for fitting onto said frame are provided for feeding a fixed number of drugs, said drive box accommodating therein at least a motor and connecting to at least one of said drug cases for detachably fitting onto said inclined rails of said frame as a whole.

2. A drug storing apparatus as claimed in claim 1, wherein said frame is a cylindrical or polygonal structure and said hopper is disposed in a central portion of said frame, said drug cases being mounted on said frame with their inner ends distributed around said hopper.

3. A drug storing apparatus as claimed in claim 1, wherein said motor contained in said drive box has an axle projecting from said drive box, and said drive box has a plurality of projecting guide rails along which each of said drug cases may slidably detach from or engage with said drive box so that said feeding element may detach from or couple with said axle of said motor.

4. A drug storing apparatus as claimed in claim 1, wherein at least a sensor is disposed at a middle portion of each of said drug cases for detecting the amount of drugs stored therein.

5. A drug storing apparatus as claimed in claim 4, wherein said drug cases are transparent or translucent.

6. A drug storing apparatus as claimed in claim 1, wherein said feeding element has a stirring element capable of free rotation disposed at an inner bottom side of each of said drug cases, said stirring element having a plurality of panels spaced apart from each other and disposed about an outer periphery thereof for separating and containing a fixed number of tablets or pills for discharge via said outlet at said inner end of each of said drug cases, said stirring element further having a rotary axle with a coupling at a bottom side thereof for coupling to said axle of said motor disposed inside said drive box.

7. A drug storing apparatus as claimed in claim 6, wherein said coupling has a bottom edge provided with a plurality of grooves, and said axle of said motor is provided with at least one pin disposed perpendicularly to said axle of said motor for fitting into said grooves of said coupling for retaining and driving said stirring element.

8. A drug storing apparatus as claimed in claim 6, wherein said stirring element is a top-like structure.
