Abstract

A product management system (100) includes—a continuous first track (104), including a lug queuing section (108), a lug engagement section (110), and a product engagement section (112), each section being configured and adapted to effectuate specific lug movement steps, —a continuous chain (116) partially following the track configured and adapted to actuate lugs (106) about at least a portion of the track, —a series of lugs (106) moveably disposed along the track (104) configured for moving a product along the product engagement section of the track, —a star wheel (120) disposed at the lug engagement section (110) of the track (104) configured for metering lugs (106) to engage the chain (116) from the queuing section (108) of the track (104) and to control a variable pitch between each of the lugs along the transferring chain, —and a magnetism source (122) configured to direct the lugs (106) to the queuing section (108), and to the end of the queuing section (108).

First claim

What is claimed is:

1. A product management system comprising:
a continuous first track, including a lug queuing section, a lug engagement section, and a product engagement section, each section being configured and adapted to effectuate specific lug movement steps;
a continuous chain partially following the continuous first track configured and adapted to actuate lugs about at least a portion of the continuous first track;
a series of lugs moveably disposed along the continuous first track configured for moving a product along the product engagement section of the continuous first track;
a star wheel disposed at the lug engagement section of the continuous first track configured for metering lugs to engage the chain from the queuing section of the track and to control a variable pitch between each of the lugs along the transferring chain;
and a magnetism source disposed proximate or within the queuing sections, wherein the magnetism source is configured to pull the lugs to the queuing section when activated.

2. The product management system of claim 1 , wherein the continuous chain and continuous first track are disposed within a panel.

3. The product management system of claim 1 , wherein the first track is oriented in a horizontal plane.

4. The product management system of claim 1 , wherein each lug includes an arm configured and adapted to engage the product.

5. The product management system of claim 1 , wherein the star wheel is programmed to move independent of the chain.

6. The product management system of claim 5 , wherein the star wheel is actuated by a controller for controlling pitch between each of the lugs along the chain.

7. The product management system of claim 1 , wherein the star wheel is disposed on and actuated by a vertical shaft, wherein a controller programmed to rotate the vertical shaft at a rate corresponding with a desired spacing between each of the lugs along the product engagement section of the first track.

8. The product management system of claim 1 , wherein the star wheel includes a series of slots configured to complement a base of the lug.

9. The product management system of claim 1 , wherein the chain includes a series of vertically aligned members configured and adapted to engage the lugs in order to drive the lugs along the first track.

10. The product management system of claim 1 , wherein each lug includes a cylindrical portion disposed within the first track configured and adapted to hold the position the lug along the first track.

11. The product management system of claim 10 , wherein the cylindrical portion of each lug includes a flange protruding radially therefrom.

12. The product management system of claim 1 , wherein the chain includes a series of vertically aligned members, wherein each vertically aligned member is configured and adapted to engage a leading cylindrical member protruding from a base of each lug in order to drive the lugs along the first track.

13. The product management system of claim 12 , wherein each lug includes a trailing cylindrical member configured and adapted to improve stability of each lug within the first track.

14. The product management system of claim 1 , including a disengagement mechanism disposed along the first track configured to disengage the lugs from the chain and direct the lugs to the lug queuing section.

15. The product management system of claim 1 , wherein each lug includes a magnet reacting material.

16. The product management system of claim 1 , wherein the magnetism source configured and adapted to bias each lug towards a lug queuing section end proximate to the lug engagement section.

17. The product management system of claim 1 , further comprising conveyor configured for feeding products to the product engagement section.

18. The product management system of claim 1 , wherein the magnetism source is directly attached to the continuous first track.

19. A product management system comprising:
a continuous first track, including a lug queuing section, a lug engagement section, and a product engagement section, each section being configured and adapted to effectuate specific lug movement steps;
a continuous chain partially following the continuous first track configured and adapted to actuate lugs about at least a portion of the continuous first track, wherein the continuous chain and the continuous first track are disposed within a panel such that the chain is disposed within a secondary channel within the panel located below the continuous first track;
a serious of lugs moveably disposed along the continuous first track configured for moving a product along the product engagement section of the continuous first track;
a star wheel disposed at the lug engagement section of the continuous first track configured for metering lugs to engage the chain from the queuing section of the track and to control a variable pitch between each of the lugs along the transferring chain; and
a magnetism source configured to direct the lugs to the queueing sections.

20. A product management system comprising:
a panel including:
a first continuous track, including a lug queuing section, a lug engagement section, and a product engagement section, each section being configured and adapted to effectuate specific lug movement steps;
a second continuous track partially following the first continuous track located below the first track;
a continuous transferring chain disposed within the second continuous track configured and adapted to actuate lugs about at least a portion of the track;
a series of lugs moveably disposed along the track configured for effectuating a product along the product engagement section of the track, wherein each lug includes a base, a magnet, a cylindrical member protruding from the base and disposed within the first continuous track, and an arm configured and adapted to engage the product;
a star wheel disposed at the lug engagement section of the first track configured for metering lugs in order to engage the transferring chain from the queuing section of the track, wherein the star wheel is actuated independent of the transferring chain; and
a magnetism source configured to direct the lugs to the queuing section.
