Abstract

A cassette for an object counting and dispensing system includes a base and a stepped side wall which together define a central open reservoir portion and at least one peripheral covered tray portion having an exit. Each cassette is adapted to feed and guide a range of sizes and shapes of tablets toward the exit. Only a few standard sizes of cassettes are needed to accommodate all discrete objects, e.g., tablets and capsules.

Claims

1. A cassette for a system for feeding and counting discrete objects, said cassette comprising:

a) a reservoir adapted to store a plurality of discrete objects;

b) a substantially horizontal stationary tray area including an exit hole; and

c) a guide which guides the discrete objects about said tray area toward said exit hole.

2. A cassette according to claim 1, wherein:

said reservoir is provided with a cover.

3. A cassette according to claim 1, wherein:

said tray area is covered.

4. A cassette according to claim 1, wherein:

said guide includes at least one guide wall within said tray area.

5. A cassette according to claim 4, further comprising:

said discrete objects, each of said discrete objects having a substantially common height, and

said guide wall has a height of approximately 1.2 to 1.8 times said substantially common height.

6. A cassette according to claim 5, further comprising:

said discrete objects, each of said discrete objects having a substantially common width, and

said guide includes a peripheral, where said guide wall is separated from said peripheral wall of said tray area by a narrows which has a narrows width equal to between 2 to 4 times said substantially common width.

7. A cassette according to claim 1, further comprising:

said discrete objects, each of said discrete objects having a substantially common width, and

said guide includes a peripheral, where said guide wall is separated from said peripheral wall of said tray area by a narrows which has a narrows width equal to between 2 to 4 times said substantially common width.

8. A cassette according to claim 1, wherein:

said guide includes a peripheral wall, and a channel is provided in said tray area along a portion of said peripheral wall, said channel leading toward said exit.

9. A cassette according to claim 8, further comprising:

said discrete objects, each of said discrete objects having a substantially common width, and said channel has a width equal to between 0.5 to 1.5 times said common width.

10. A cassette according to claim 1, wherein:

said cassette includes a lower metal portion.

11. A cassette according to claim 1, wherein:

said cassette includes a recess on a bottom surface thereof.

12. A cassette according to claim 1, wherein:

a lowermost portion of said reservoir has a lateral passage into said tray area.

13. A cassette according to claim 1, further comprising:

d) a movable gate adapted to block said exit hole.

14. A cassette according to claim 13, wherein:

said gate comprises a metal leaf spring.

15. A cassette according to claim 1, further comprising:

d) a shelf above said tray area, said shelf including a second exit hole and a second guide which guides the discrete objects about said shelf toward said second exit hole.

16. A cassette according to claim 15, wherein:

said shelf includes a central opening, said opening providing a passage between said reservoir and said tray area.

17. A cassette for a system for feeding and counting discrete objects, said cassette comprising:

a) a reservoir adapted to store a plurality of the discrete objects;

b) a first partially covered tray area including a first exit hole; and

c) a second partially covered tray area including a second exit hole, said second covered tray area located above said first covered tray area,

wherein said reservoir is in communication with both said first and second partially covered tray areas.

18. A cassette according to claim 17, further comprising:

d) a guide which guides the discrete objects about portions of said first and second tray areas toward said first and second exit holes.

19. A cassette according to claim 17, wherein:

said first and second exit holes are vertically offset.

20. A cassette according to claim 17, wherein:

said first tray portion includes a third hole vertically aligned with said second exit hole of said second tray portion.

21. A cassette according to claim 17, further comprising:

d) a gate means for independently blocking said first and second exit holes.

22. A cassette according to claim 17, further comprising:

a cover for said reservoir.

23. A cassette for a system for feeding and counting discrete objects, said cassette comprising:

a) a reservoir adapted to store a plurality of discrete objects;

b) a substantially flat horizontal tray area including a periphery and an exit hole along said periphery; and

c) at least one guide wall discrete from said periphery which guides the discrete objects about said tray area toward said exit hole.

24. A cassette for a system for feeding and counting discrete objects, said cassette comprising:

a) a reservoir adapted to store a plurality of discrete objects; and

b) a substantially horizontal tray area including a peripheral wall, an exit hole located adjacent said peripheral wall, and a channel along a portion of said peripheral wall leading toward said exit.

25. A cassette for a system for feeding and counting discrete objects, said cassette comprising:

a) a reservoir adapted to store a plurality of discrete objects;

b) a substantially horizontal stationary tray area including an exit hole; and

c) a guide which guides the discrete objects about said tray area toward said exit hole,

wherein said cassette includes a recess on a bottom surface thereof.

26. A cassette for a system for feeding and counting discrete objects, said cassette comprising:

a) a reservoir adapted to store a plurality of discrete objects;

b) a substantially horizontal stationary tray area including an exit hole;

c) a guide which guides the discrete objects about said tray area toward said exit hole; and

d) a movable gate adapted to block said exit hole, said gate comprising a metal leaf spring.

27. A cassette for a system for feeding and counting discrete objects, said cassette comprising:

a) a reservoir adapted to store a plurality of discrete objects;

b) a substantially horizontal stationary tray area including an exit hole;

c) a guide which guides the discrete objects about said tray area toward said exit hole; and

d) a shelf above said tray area, said shelf including a second exit hole, a second guide which guides the discrete objects about said shelf toward said second exit hole, and a central opening providing a passage between said reservoir and said tray area.
