Abstract

An object counting and dispensing system includes a vibration system, a mounting assembly for coupling a cassette to the vibration system, a chute configured to receive discrete objects from the cassette, and an object sensing system which senses and counts objects fed from the cassette. Each cassette includes a base and a stepped side wall which together define a central open reservoir portion and a peripheral covered tray portion. Cassettes are mounted to the mounting assembly in manner which permits rapid and secure coupling and decoupling. A preferred coupling and decoupling system includes an electromagnet. Each cassette is able 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, for which the counter is adapted. A universal hopper can be attached to the mounting assembly.

Claims

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

a) a vibration system which vibrates in a substantially horizontally plane in a rotational direction;

b) a mounting assembly rigidly coupled to said vibration system;

c) at least one cassette adapted to be removably rigidly coupled to said mounting assembly, each said cassette having a reservoir portion which stores the discrete objects, a substantially planar tray portion in which a portion of the discrete objects travel in said rotational direction when said cassette is vibrated by said vibration system, and an exit through which the discrete objects can be exited; and

d) an object counting system which counts the discrete objects exiting said exit.

2. A system according to claim 1, wherein:

said mounting assembly includes an activatable electromagnet, and each said cassette includes a metal element which is coupled to said electromagnet when said electromagnet is activated.

3. A system according to claim 2, wherein:

said electromagnet has a cross-sectional shape, and a bottom portion of each said cassette includes a recess substantially having said cross-sectional shape.

4. A system according to claim 2, wherein;

a portion of each said cassette mates with a portion of said electromagnet.

5. A system according to claim 2, wherein:

said mounting assembly includes means for removing each said cassette from said electromagnet when said electromagnet is not activated.

6. A system according to claim 1, wherein:

said mounting assembly provides a mechanical coupling to each said cassette.

7. A system according to claim 1, wherein:

each said cassette includes a guide which feeds the discrete objects single file to said exit.

8. A system according to claim 1, wherein:

each said cassette includes a gate movable between a closed position relative to said exit and an open position relative to said exit.

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

d) a solenoid having a shaft provided with a magnet,

wherein said gate is comprised of metal and activation of said solenoid causes said magnet to deflect said gate into said open position relative to said exit.

10. A system according to claim 1, wherein:

said at least one cassette is a plurality of cassettes, each of said cassettes having a tray portion of a different height from the others.

11. A system according to claim 1, wherein:

each said cassette includes an alignment means for aligning said exit relative to said object counting system.

12. A system according to claim 1, further comprising:

e) a funnel adapted to be coupled above said object counting system.

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

e) an open bowl adapted to be removably rigidly coupled to said mounting assembly.

14. A system according to claim 1, wherein:

said at least one cassette includes a plurality of exits from which the discrete objects exit.

15. A system according to claim 14, wherein:

said at least one cassette includes at least two vertically adjacent tray portions, each of said at least two tray portions including a respective exit at which the discrete objects exit said cassette.

16. A system for feeding and counting discrete objects, comprising:

a) a vibration system;

b) a mounting assembly rigidly coupled to said vibration system, said mounting assembly including an electromagnet;

c) at least one discrete object container including a metal element adapted to be removably rigidly coupled to said electromagnet, each said discrete object container having a reservoir portion which stores a plurality of the discrete objects, an area in which a portion of said plurality of discrete objects travel when each said discrete object container is vibrated by said vibration system, and an exit through which the discrete objects can be fed; and

d) an object counting system which counts the discrete objects exiting said exit when said discrete object container is coupled to said mounting assembly.

17. A system according to claim 16, wherein:

said discrete object container is a cassette having a substantially planar covered tray portion and a reservoir portion.

18. A system according to claim 17, wherein:

said at least one cassette is a plurality of cassettes, wherein said tray portion of said cassettes has a different height from the others.

19. A system according to claim 17, wherein:

each said cassette includes a plurality of exits from which the discrete objects can exit.

20. A system according to claim 19, wherein:

each said cassette includes at least two vertically adjacent tray portions, each of said at least two tray portions including a respective exit at which the discrete objects exit said cassette.

21. A system according to claim 20, wherein:
