Abstract

A medicament dispensing cell (12) is provided which is used in large, automated dispensing machines (10) to provide rapid and accurate dispensing of medicament dosage forms such as tablets (124), capsules, or pills. The cell (12) includes a housing (20) for storage of tablets (124) and includes a rotatable platen conveyor assembly (68) which moves the tablets (124) along a passageway (96) and through an outlet opening (36). The passageway (96) includes a restricted throat section (98) defined by a bushing (78) and an inclined roller (100). The roller (100) is oriented so as to prevent simultaneous passage of two tablets (124) through the throat section (98).

Claims

1. A dispensing cell for dispensing discrete bodies and comprising:

a housing including a storage section that holds said bodies, a dispensing outlet, and a passageway between the storage section and the outlet; and

a conveyor assembly that conveys said discrete bodies from the storage section through the passageway and out said outlet,

said passageway including a restricted throat section between said storage section and said outlet, said throat section defined by a pair of spaced apart components, one of said components comprising a roller presenting an upper margin and a lower margin, said roller oriented so that the upper margin thereof is closer to the other component than said lower margin thereof, so as to prevent simultaneous passage of two of said bodies through the throat section.

2. The cell of claim 1, said other components comprising a rotatable bushing forming a part of said conveyor assembly.

3. The cell of claim 2, said bushing having a resilient, body-engaging outer surface.

4. The cell of claim 1, said roller being mounted for free rotation.

5. The cell of claim 1, the position of said roller being adjustable relative to said other components so as to permit adjustment of the effective size of said throat section.

6. The cell of claim 1, said storage section including a sloped wall leading toward said throat section.

7. The cell of claim 1, including a rigid wall between said throat and said outlet, there being at least one resilient finger located to urge said discrete bodies toward the rigid wall during conveying of the rigid body between said throat section and said outlet.

8. The cell of claim 7, there being a pair of spaced apart resilient fingers.

9. The cell of claim 1, said conveyor assembly comprising a rotatable platen.

10. The cell of claim 9, said platen presenting an upper body-supporting surface, said surface having a plurality of upstanding ribs.

11. The cell of claim 1, said passageway configured for the passing and dispensing of medicament dosage forms.
