Abstract

In some embodiments, apparatuses and methods are provided herein useful to the sortation of products using a conveyor assembly. In some embodiments, there is provided a system for receiving and sorting products shipped to a shopping facility including: a delivery location at a shopping facility configured to receive a shipment of products; a conveyor assembly comprising: a product identification module configured to read identification data from an identification label disposed on a product; a plurality of sortation modules configured to move the product to one of a predetermined plurality of sortation destination areas; a control circuit operatively coupled to the product identification module and to each of the sortation modules, the control circuit configured to: receive the identification data from the product identification module; determine the sortation destination area for the product based at least on one of shopping facility data and shipping data regarding the product as sortation criteria; and cooperate with the plurality of sortation modules to move the product to the determined sortation destination area.

First claim

What is claimed is:

1. A conveyor assembly comprising:
a plurality of sortation modules configured to move a product to one of a predetermined plurality of sortation destination areas;
a control circuit operatively coupled to each of the sortation modules, the control circuit configured to:
determine the destination area for the product; and
communicate with the sortation module corresponding to the determined destination area to divert the product to the determined destination area;

wherein the control circuit and the plurality of sortation modules cooperate to reconfigure sortation destination areas to match positions of the sortation modules when one sortation module is interchanged or replaced with another sortation module.

2. The conveyor assembly of claim 1 , wherein each sortation module comprises:
a uni-directional travel portion with a plurality of rollers configured to propel the product in a first direction along the rollers; and
a bi-directional sorting portion with a first set of rollers configured to propel the product in the first direction and a second set of rollers to divert the product in a second direction to a sortation destination area.

3. The conveyor assembly of claim 1 , wherein one sortation module is configured for coupling to multiple parts of a second sortation module such that the plurality of sortation modules define a plurality of different geometric arrangements.

4. The conveyor assembly of claim 2 , wherein the travel portion and the sorting portion of each sortation module form a single unitary structure.

5. The conveyor assembly of claim 2 , wherein at least one of the rollers of each sortation module comprises a powered roller with an adjustable rotation speed.

6. The conveyor assembly of claim 5 , further comprising a plurality of sensors disposed at predetermined locations on the plurality of sortation modules to detect positions of the product traveling along the plurality of sortation modules.

7. The conveyor assembly of claim 6 , wherein the control circuit is operatively coupled to the powered roller of each sortation module and to the plurality of sensors, the control circuit configured to:
determine the position of the product relative to the position of an adjacent product on the plurality of sortation modules; and
activate the powered roller to adjust the speed of the product to maintain a predetermined minimum separation distance between it and the adjacent product.

8. The conveyor assembly of claim 1 , wherein the control circuit comprises a controller core that communicates with each sortation module to track the position of each sortation module.

9. The conveyor assembly of claim 1 , wherein each sortation module communicates with other sortation modules to track the position of each sortation module relative to one another.

10. The conveyor assembly of claim 2 , wherein each sortation module further comprises a conveyor coupling portion having a plurality of rollers and coupling the sorting portion to a destination area, the conveyor coupling portion being collapsible to facilitate storage of the sortation module.

11. A method of delivering products along a conveyor assembly comprising:
providing a conveyor assembly comprising a plurality of sortation modules and configured to move products to a predetermined plurality of sortation destination areas;
by a control circuit, determining a destination area for a product from the predetermined plurality of sortation destination areas;
propelling the product along the plurality of sortation modules;
communicating with a sortation module corresponding to the determined destination area;
by the control circuit, diverting the product to the determined destination area; and
by the control circuit, reconfiguring the predetermined plurality of sortation destination areas to match positions of the sortation modules when one sortation module is interchanged or replaced with another sortation module.

12. The method of claim 11 , wherein each sortation module comprises:
a uni-directional travel portion with a plurality of rollers configured to propel the product in a first direction along the rollers; and
a bi-directional sorting portion with a first set of rollers configured to propel the product in the first direction and a second set of rollers to divert the product in a second direction to a sortation destination area.

13. The method of claim 12 , wherein the uni-directional travel portion of one sortation module is configured for coupling to multiple parts of a second sortation module such that the plurality of sortation modules define a plurality of different geometric arrangements.

14. The method of claim 12 , wherein the travel portion and the sorting portion of each sortation module form a single unitary structure.

15. The method of claim 12 , wherein at least one of the rollers of each sortation module comprises a powered roller with an adjustable rotation speed.

16. The method of claim 15 , wherein a plurality of sensors are disposed at predetermined locations on the plurality of sortation modules to detect positions of the product traveling along the plurality of sortation modules.

17. The method of claim 16 , further comprising, by the control circuit:
determining the position of the product relative to the position of an adjacent product on the plurality of sortation modules; and
activating the powered roller to adjust the speed of the product to maintain a predetermined minimum separation distance between it and the adjacent product.

18. The method of claim 11 , further comprising, by a controller core, communicating with each sortation module to track the position of each sortation module.

19. The method of claim 11 , further comprising, by each sortation module, communicating with other sortation modules to track the position of each sortation module relative to one another.

20. The method of claim 12 , wherein each sortation module further comprises a conveyor coupling portion having a plurality of rollers and coupling the sorting portion to a destination area, the conveyor coupling portion being collapsible to facilitate storage of the sortation module.
