Abstract

A product management system ( 100 ) including a first panel ( 102 ) with a first continuous track ( 106 ) including a queuing section, a product engagement section and a return section, and a first series of magnetic sources ( 115 ) disposed circumferentially along the first continuous track ( 106 ). A first series of lugs ( 116 ) are movably dispersed around the first continuous track ( 106 ) configured to react to the first series of magnetic sources in order to increase or decrease a velocity of each lug ( 116 ) of the first series of lugs along the first continuous track ( 116 ) and a product engagement member ( 118 ) attached to each lug configured and adapted to actuate to engage a product.

First claim

What is claimed is:

1. A product management system comprising:
a first continuous track including a product engagement section and a return section; and
a first series of magnetic sources disposed along the first continuous track;
a first series of lugs movably dispersed around the first continuous track configured to react to the first series of magnetic sources in order to increase or decrease a velocity of each lug of the first series of lugs along the first continuous track; and
a product engagement member attached to each lug configured and adapted to actuate to engage a product,
wherein each lug comprises at least one of: (i) a primary base and a secondary base, and (ii) a first product engagement member base and a second product engagement member base,
wherein at least one of the primary base and the first product engagement member base is controlled by the magnetic source, and at least one of the secondary base and the second product engagement member base is independent of the magnetic source.

2. The product management system of claim 1 , further comprising:
a second series of magnetic sources disposed along a second continuous track disposed parallel to the first continuous track; and
a second series of lugs movably dispersed around the second continuous track configured to react to the second series of magnetic sources in order to increase or decrease a velocity of each lug of the second series of lugs along the second continuous track.

3. The product management system of claim 2 , wherein the lugs of the first series of lugs and the lugs of the second series of lugs are alternatingly arranged along the first track and along the second track so as to alternate in the direction of movement of the lugs.

4. The product management system of claim 1 , wherein each lug includes the first product engagement member base and the second product engagement member base,
wherein the first product engagement member base includes a first product engagement member and the second product engagement member base includes a second product engagement member.

5. The product management system of claim 1 , wherein the product engagement member includes at least one arm actuatable in two Cartesian directions.

6. The product management system of claim 5 , wherein the arm includes at least one semi-circular end configured and adapted to engage a can or bottle product.

7. The product management system of claim 5 , wherein the arm includes a paddle configured and adapted to engage a trailing or leading side of the product.

8. The product management system of claim 7 , wherein each lug includes a first paddle and second paddle.

9. The product management system of claim 1 , further comprising a first cam and a second cam configured for supporting the series of lugs.

10. The product of management system of claim 9 , wherein each of the cams partially follow the first track and includes at least a pair of undulations.

11. The product management system of claim 1 , wherein the first series of magnetic sources includes a series of magnetic plates that are disposed along the first track, and a series of coils configured and adapted to activate each of the magnetic plates.

12. The product management system of claim 11 , wherein a controller controls each of the magnetic plates.

13. The product management system of claim 12 , where the controller is configured and adapted to provide a configurable speed profile for lugs traveling along the first track.

14. The product management system of claim 13 , wherein the speed profile includes acceleration sections, deceleration sections, and constant speed sections.

15. The product management system of claim 1 , including at least one star wheel disposed proximate to the lug engagement section of the first continuous track configured and adapted to meter products to the lug engagement section.

16. The product management system of claim 15 , further comprising a second star wheel.

17. A product management system, comprising:
a first continuous track including a product engagement section and a return section;
a first series of magnetic sources disposed along the first continuous track;
a first series of lugs movably dispersed around the first continuous track configured to react to the first series of magnetic sources in order to increase or decrease a velocity of each lug of the first series of lugs along the first continuous track;
a product engagement member attached to each lug configured and adapted to actuate to engage a product;
a second series of magnetic sources disposed along a second continuous track disposed parallel to the first continuous track; and
a second series of lugs movably dispersed around the second continuous track configured to react to the second series of magnetic sources in order to increase or decrease a velocity of each lug of the second series of lugs along the second continuous track,
wherein the lugs of the first series of lugs and the lugs of the second series of lugs are alternatingly arranged along the first track and along the second track so as to alternate in the direction of movement of the lugs.

18. The product management system of claim 17 , wherein each lug includes a first product engagement member base and a second product engagement member base,
wherein the first product engagement member base includes a first product engagement member and the second product engagement member base includes a second product engagement member.

19. A product management system, comprising:
a first continuous track including a product engagement section and a return section;
a first series of magnetic sources disposed along the first continuous track;
a first series of lugs movably dispersed around the first continuous track configured to react to the first series of magnetic sources in order to increase or decrease a velocity of each lug of the first series of lugs along the first continuous track; and
a product engagement member attached to each lug configured and adapted to actuate to engage a product,
wherein each lug includes a first paddle and second paddle, and
wherein the first paddle and the second paddle are attached to the lug by a pantograph linkage.

20. The product management system of claim 19 , wherein each lug consists of a primary base and a secondary base, wherein the primary base is controlled by the magnetic source and the secondary base is independent of the magnetic source, and wherein each base includes one of the first paddle and the second paddle.
