Abstract

The present invention relates to an automated system for pharmaceutical singulation, counting and dispensing, whereby a bulk of stored pharmaceutical units are singulated into a single file line for counting and dispensing. With reference to the drawings, the pharmaceutical singulation, counting and dispensing system comprises generally, a deck assembly (A), a cylindrical chamber (B), a rotatable transport ring (C), a plurality of adjustable fingers (D), an adjustable reciprocating member (E), an adjustable rotatable member (F), a counting system (G), a hopper (H), and a control system (I).

Claims

1. An apparatus for counting pharmaceutical units, comprising:

(a) a deck assembly;

(b) a cylindrical chamber carried by the deck assembly, wherein the walls of the chamber are oriented vertically;

(c) a pharmaceutical unit storage section, carried by the deck assembly and positioned within the cylindrical chamber, the storage section having walls, a floor and an opening adjacent the floor from which to discharge the pharmaceutical units;

(d) a horizontally oriented transport ring carried by the deck assembly and rotatable relative to the walls of the cylindrical chamber and the walls of the storage section, the transport ring having an inner perimeter, an outer perimeter and a top surface, wherein the outer perimeter of the transport ring is positioned within the walls of the cylindrical chamber, and the storage section is positioned within the inner perimeter of the transport ring, thereby forming a passage for the pharmaceutical units between the walls of the cylindrical chamber and the walls of the storage section, and further wherein the floor and opening of the storage section are oriented above the transport ring, to allow the pharmaceuticals units to be fed by gravity onto the top surface of the transport ring;

(e) a motor for rotating the transport ring;

(f) an outlet in the cylindrical chamber for discharging the pharmaceutical units from the transport ring;

(g) a hopper for receiving the pharmaceutical units discharged through the outlet;

(h) a counting system, for counting the pharmaceutical units discharged to the hopper; and

(i) a controller for receiving prescription data, initiating a count cycle, controlling the transport ring motor, receiving a pharmaceutical unit count from the counting system and ending a count cycle.

2. The apparatus of claim 1, wherein the storage section is cylindrical, the walls of the storage section are oriented vertically and extend above the transport ring, and the walls of the storage section form the inner wall of the passage for the pharmaceutical units.

3. The apparatus of claim 1, further comprising means to vertically singulate pharmaceutical units on the transport ring.

4. The apparatus of claim 3, wherein the means to vertically singulate pharmaceutical units comprises a plurality of fingers depending downward toward the transport ring.

5. The apparatus of claim 4, wherein the fingers are vertically adjusted to singulate the pharmaceutical units to one unit in height.

6. The apparatus of claim 4, wherein the fingers are configured in a reverse staircase arrangement to step down the height as the pharmaceutical units travel on the transport ring.

7. The apparatus of claim 3, further comprising a reciprocating member, positioned along the inner perimeter of the transport ring, to horizontally singulate pharmaceutical units.

8. The apparatus of claim 7, wherein a gap between the reciprocating member and the wall of the cylindrical chamber can be varied, to accommodate pharmaceutical units of varying size, shapes, textures and weight.

9. The apparatus of claim 1, wherein the floor of the storage section is sloped downward to the opening in the storage section.

10. The apparatus of claim 1, wherein the transport ring further comprises surface configuration members to alter the coefficient of friction along the transport ring during rotation thereof.

11. A system for storing, counting and dispensing pharmaceutical units, comprising:

(a) a plurality of linked individual bins, each of the bins comprising

a deck assembly;

a cylindrical chamber carried by the deck assembly, wherein the walls of the chamber are oriented vertically;

a pharmaceutical unit storage section, carried by the deck assembly and positioned within the cylindrical chamber, the storage section having walls, a floor and an opening adjacent the floor from which to discharge the pharmaceutical units;

a horizontally oriented transport ring carried by the deck assembly and rotatable relative to the walls of the cylindrical chamber and the walls of the storage section, the transport ring having an inner perimeter, an outer perimeter and a top surface, wherein the outer perimeter of the transport ring is positioned within the walls of the cylindrical chamber, and the storage section is positioned within the inner perimeter of the transport ring, thereby forming a passage for the pharmaceutical units between the walls of the cylindrical chamber and the walls of the storage section, and further wherein the floor and opening of the storage section are oriented above the transport ring, to allow the pharmaceuticals units to be fed by gravity onto the top surface of the transport ring;

a motor for rotating the transport ring;

an outlet in the cylindrical chamber for discharging the pharmaceutical units from the transport ring;

a hopper for receiving the pharmaceutical units discharged through the outlet;

a counting system, for counting the pharmaceutical units discharged to the hopper; and

(b) a controller for receiving prescription data and, with regard to the bin containing the pharmaceutical unit identified in the prescription data, initiating a count cycle, controlling the transport ring motor, receiving a pharmaceutical unit count from the counting system and ending a count cycle.

12. The system of claim 11, further comprising (i) a bar code scanner, for scanning a bar code placed on a bottle to be filled with pharmaceutical units;

(ii) indicator lights on each of the bins; and

(iii) a master controller for receiving the bar code data, matching the data to the prescription data and activating the indicator light corresponding to the bin containing the pharmaceutical units corresponding to the prescription data.

13. The system of claim 11, wherein the storage section is cylindrical, the walls of the storage section are oriented vertically, and extend above the transport ring, and the walls of the storage section form the inner wall of the passage for the pharmaceutical units.

14. The system of claim 11, further comprising means to vertically singulate pharmaceutical units on the transport ring.

15. The system of claim 14, wherein the means to vertically singulate pharmaceutical units comprises a plurality of fingers depending downward toward the transport ring.

16. The system of claim 15, wherein the fingers are vertically adjusted to singulate the pharmaceutical units to one unit in height.

17. The system of claim 11, further comprising a reciprocating member, positioned along the inner perimeter of the transport ring, to horizontally singulate pharmaceutical units.

18. The system of claim 17, wherein a gap between the reciprocating member and the wall of the cylindrical chamber can be varied, to accommodate pharmaceutical units of varying size, shapes, textures and weight.

19. The system of claim 11, wherein the floor of the storage section is sloped downward to the opening in the storage section.

20. The system of claim 11, wherein the transport ring further comprises surface configuration members to alter the coefficient of friction along the transport ring during rotation thereof.
