Abstract

A medicament dispensing cell for use in an automatic dispensing machine includes a housing defining a medicament storage section, a discharge section leading to an outlet, a passage between the sections, a rotatable platen and a dispensing assembly for dispensing medicament in single file from the storage section to the discharge section. A resilient, flexible bushing having outwardly extending fingers encloses the hub of the platen for conveying medicament through the passage. The platen includes a plurality of spirally configured conveying members defined on the surface thereof and the dispensing assembly includes a selectively adjustable passage wall for adjusting the breadth of the passage.

Claims

1. In an automatic medicament dispensing machine, a dispensing cell for dispensing units of medicament comprising;

dispensing means positioned in said passage defining the side-to-side width thereof as greater than the breadth of a medicament unit and less than twice the breadth thereof for dispensing medicament units from said storage section to said discharge section,

said platen means including a disk-shaped platen having a hub,

said housing including a guide wall extending from said passage adjacent said hub into said discharge section and terminating adjacent the periphery of said platen for guiding medicament units thereto for conveyance to said outlet,

said dispensing means including a passage wall spaced from said hub and defining said passage therebetween, and including a resilient, flexible bushing surrounding said hub having a plurality of outwardly extending fingers positioned for engaging and conveying medicament units through said passage during rotation of said platen.

2. The dispensing cell as set forth in claim 1, said dispensing means further including a funnel wall extending from said passage wall into said storage section and positioned for funneling medicament units into said passage.

3. The dispensing cell as set forth in claim 1, said dispensing means including adjusting means for selectively adjusting the side-to-side position of said passage wall in order to adjust the width of said passage.

4. The dispensing cell as set forth in claim 3, said adjusting means including means shiftably mounting said passage wall with said housing and means for selectively holding said passage wall in a selected position.

5. The dispensing cell as set forth in claim 4, said dispensing means further including an indicator extending therefrom for shifting therewith and extending to a position adjacent indicia configured on said housing, said indicator and indicia cooperatively indicating the position of said passage wall and thereby the width of said passage.

6. The dispensing cell as set forth in claim 1, said dispensing cell being subject to static charge causing medicament units to cling to said housing walls, said platen means being composed of conductive material for reducing said static charge.

7. The dispensing cell as set forth in claim 1, said housing including chamber walls defining a chamber configured for receiving a desiccant packet therein.

8. The dispensing cell as set forth in claim 7, said chamber being positioned adjacent said storage section, said chamber walls including slots defined therein for air exchange with said storage section.

9. In an automatic medicament dispensing machine, a dispensing cell for dispensing units of medicament comprising:

a housing having walls defining a storage section, a discharge section leading to an outlet, and a passage between said sections;

rotatable platen means forming at least a portion of the bottom wall of said sections and passage for conveying medicament units during rotation of said platen means from said storage section to said outlet by way of said passage and discharge section, the dispensing machine having means for selectively rotating said platen means; and

dispensing means positioned in said passage defining the side-to-side width thereof as greater than the breadth of a medicament unit and less than twice the breadth thereof for dispensing medicament units from said storage section to said discharge section;

said platen means including a disk-shaped platen having a hub and presenting an upper surface having a plurality of spirally arranged conveying members defined thereon extending from said hub and configured for spacing medicament units in said discharge section during rotation of said platen.

10. The dispensing cell as set forth in claim 9, said housing including a guide wall extending from said passage adjacent said hub into said discharge section and terminating adjacent the periphery of said platen for guiding medicament units thereto for conveyance to said outlet.

11. The dispensing cell as set forth in claim 9, said dispensing means including a passage wall spaced from said hub and defining said passage therebetween.

12. The dispensing cell as set forth in claim 11, said dispensing means including a resilient, flexible bushing surrounding said hub having a plurality of outwardly extending fingers positioned for engaging and conveying medicament units through said passage during rotation of said platen.

13. In an automatic medicament dispensing machine, a dispensing cell for dispensing units of medicament comprising:

a housing having walls defining a storage section, a discharge section leading to an outlet, and a passage between said sections,

rotatable platen means forming at least a portion of the bottom wall of said sections and passage for conveying medicament units during rotation of said platen means from said storage section to said outlet by way of said passage and discharge section, the dispensing machine having means for selectively rotating said platen means, and

dispensing means positioned in said passage defining the side-to-side width thereof as greater than the breadth of a medicament unit and less than twice the breadth thereof for dispensing medicament units from said storage section to said discharge section,

said housing including a guide wall extending from said passage opposite said dispensing means into said discharge section and terminating adjacent the periphery of said platen for guiding medicament units thereto for conveyance to said outlet,

said platen means including a disk-shaped platen having a hub and presenting an upper surface having a plurality of spirally arranged conveying members defined thereon extending from said hub and configured for spacing medicament units in said discharge section during rotation of said platen, said platen being composed of conductive material for reducing static charge between said cell and medicament units,
