Abstract

An apparatus and method for article dispensing includes an article bay for holding a plurality of articles, and a conveying mechanism below the article bay operable to move an article. The conveying mechanism can repeat such movement for succeeding articles to a dispensing location. Succeeding articles can optionally be placed on top of the articles directly on the conveying mechanism. The succeeding articles are retained until they move by gravity to the conveying mechanism.

15. The article dispenser of claim 1 wherein said conveying mechanism is motorized.

16. The article dispenser of claim 1 wherein said conveying mechanism is adapted to connect to a motor.

17. The article dispenser of claim 16 wherein said motor is an electrical motor.

18. The article dispenser of claim 17 wherein said electrical motor includes an input adapted for connection to a controller.

19. The article dispenser of claim 1 wherein said conveying mechanism comprises an auger.

20. The article dispenser of claim 1 wherein said conveying mechanism comprises flights sized to receive an article to be dispensed therebetween.

21. The article dispenser of claim 20 wherein said auger is rotated about a longitudinal axis.

22. The article dispenser of claim 1 further comprising a motor connected to a second end of the conveying mechanism.

23. The article dispenser of claim 19 further comprising a bottom support floor upon which the auger rotatably rests and is supported by.

24. The article dispenser of claim 19 wherein the auger comprises a helical wire.

25. The article dispenser of claim 24 wherein the helical wire further comprises a central support extending along the longitudinal of the auger.

26. The article dispenser of claim 5 further comprising a retainer for at least some of said articles.

27. The article dispenser of claim 5 further comprising a deflector at or near an opening from the article bay and including a portion extending to catch and lift articles directly above lower-most articles.

28. The article dispenser of claim 27 wherein a portion of the deflector extends at an obtuse angle towards articles and terminates above lower-most articles.

29. The article dispenser of claim 6 further comprising a back wall angled inwardly at the articles.

30. The article dispenser of claim 6 wherein said top is angled downwardly at the rear of the article bay.

31. The article dispenser of claim 1 further comprising a monitor including a sensor to sense an article passing to an outlet from said article bay.

32. A dispenser assembly for holding a plurality of a product and dispensing said product one by one comprising:

(a) a housing having a bottom, back, and opposites sides;

(b) a generally unobstructed open space inside the housing adapted to hold said plurality of products;

(c) a conveying mechanism positioned at or near the bottom of the housing and positioned in the bottom of said space between the back and front of the housing.

33. A dispenser assembly for articles comprising:

(a) a helical member having a back and front ends along a longitudinal axis and comprising flights having article holding spaces therebetween, the helical member adapted to hold a row of articles to be dispensed transversely in said holding spaces and advance the articles to the front end of the helical member;

(b) a frame in which the helical member is positioned;

(c) a motor mounted to the frame and including a rotatable axle;

(d) a connection between the axle and the helical member adapted to cause rotation of the helical member around its longitudinal axis upon rotation of the axle of the motor;

(e) retaining walls positioned along the helical member on opposite sides of the longitudinal member, and extending upwardly to define a space adapted to hold, transversely of the longitudinal axis of the helical member, a plurality of articles to be dispensed in a stacked relationship of at least a lowermost layer and a succeeding layer above the lower-most layer;

(f) a retaining member positioned at or near the front of said space;

(g) an outlet from the frame at or near the front end of the helical member through which can pass an article in the front most position in the helical member.

34. The dispenser assembly of claim 33 further comprising a deflecting member near the front end of the helical member extending down from the frame to near the helical member adapted to allow an article in the helical member to pass, but deflect any article abutting and directly above the article in the helical member upon the front most article passing out of the helical member to the outlet.

35. The dispenser assembly of claim 33 wherein the articles are at least generally cylindrical.

36. The dispenser assembly of claim 33 wherein the articles are non-cylindrical.

37. The method of claim 36 wherein said articles are cylindrical containers.

38. A method of dispensing articles comprising:

(a) supporting a lower layer of articles;

(b) vertically stacking a one or more succeeding articles upon the lower layer;

(c) moving the lower layer towards an outlet;

(d) allowing an article in the lower layer closest the outlet to pass out of the outlet for dispension, reducing the number of articles in the lower layer by one, while the succeeding articles ride over one or more articles in the lower layer or, by gravity, assume a position in the lower layer.

39. The method of claim 38 wherein the cylindrical containers are beverage containers.

40. The method of claim 38 wherein the articles are products.

41. The method of claim 40 wherein the products are non-cylindrical.

43. The method of claim 38 wherein the articles are positioned in a plurality of rows vertically stacked.

44. The method of claim 38 wherein the step of supporting a lower layer of articles comprises supporting a lower layer of articles in a series from front to back.

45. The method of claim 44 wherein the lower layer is positioned along a longitudinal axis.

46. The method of claim 38 wherein the step of moving the lower layer comprises pushing the lower layer to an outlet.

47. The method of claim 38 wherein the step of moving the lower layer comprises pulling the lower layer.

48. The method of claim 38 wherein the step of retaining the succeeding articles comprises preventing movement of the succeeding articles to an outlet, but retaining succeeding articles in a defined space.

49. The method of claim 38 further comprising deflecting away from an outlet any succeeding article.

50. The method of claim 38 further comprising sensing movement of an article to or from an outlet.

51. The method of claim 38 further comprising repeating steps (c) and (d).

53. The method of claim 38 further comprising reloading articles into the vertical stack.

54. A method of dispensing articles comprising:

(a) supporting a plurality of cylindrical articles successively abutting and on top of one another from a row of articles in a bottom-most layer upwardly, the bottom-most layer having a front end and back end along a longitudinal axis;

(b) moving articles in the bottom-most layer along its longitudinal axis;

(c) dispensing an article from the bottom-most layer and creating a space in the bottom-most layer from the loss of said dispensed article.

55. The method of claim 54 further comprising allowing by gravity an article from above the bottom-most layer to fill the space in the bottom-most layer.

56. The method of claim 55 wherein the articles are generally cylindrical.
