Abstract

There is provided a conveyor assembly for sorting merchandise items. In one form, the conveyor assembly includes: a merchandise identification module; sortation modules each comprising a multi-directional sorting portion with two sets of rollers, a first wing including a third set of rollers, a second wing including a fourth set of rollers, and a controller configured to receive an IP address; a first, disassembled state of the sortation modules; a second, assembled state of the sortation modules; a merchandise database; and a control circuit configured to receive identifying information about an unsorted merchandise item, assign a unique IP address to each sortation module corresponding to the position of the sortation module, determine a sortation destination for the unsorted merchandise item, determine the sortation module corresponding to the sortation destination; and instruct the controller of the corresponding sortation module to divert the unsorted merchandise item to the sortation destination.

First claim

What is claimed is:

1. A conveyor assembly comprising:
a plurality of sortation modules configured to move and sort items, wherein each sortation module is configured to divert items to at least one sortation destination;
an assembled state of the plurality of sortation modules in which the sortation modules are coupled to one another to define a chain of sortation modules;
a control circuit communicatively coupled to each sortation module, the control circuit configured to:
assign a unique Internet Protocol (IP) address to each sortation module, each unique IP address corresponding to a position of each sortation module in the chain of sortation modules when in the assembled state;
determine a sortation destination for an unsorted item to be sorted;
determine a sortation module corresponding to the determined sortation destination; and
instruct the sortation module corresponding to the determined sortation destination to divert the unsorted item to the determined sortation destination.

2. The conveyor assembly of claim 1 , wherein each sortation module comprises a sortation module portion with a set of rollers, at least one roller of the set of rollers being a motor powered roller.

3. The conveyor assembly of claim 1 , wherein:
each sortation module comprises a first roller motor control portion and a second roller motor control portion;
the first roller motor control portion configured to control rotation of at least one roller of a set of rollers in a clockwise direction to divert items to a first sortation destination; and
the second roller motor control portion configured to control rotation of the at least one roller of the set of rollers in a counterclockwise direction to divert items to a second sortation destination.

4. The conveyor assembly of claim 1 , wherein:
the control circuit is configured to assign the unique IP addresses to the plurality of sortation modules in ascending or descending sequential order as one proceeds in a direction along the chain of sortation modules.

5. The conveyor assembly of claim 1 further comprising:
a reassembled state in which the plurality of sortation modules have been reconfigured to different relative positions in the chain of sortation modules than in the assembled state;
the control circuit assigning a new IP address to each sortation module depending on a new position of each sortation module in the chain of sortation modules.

6. The conveyor assembly of claim 1 further comprising:
a newly assembled state in which one of the plurality of sortation modules in the chain of sortation modules has been replaced with a new sortation module relative to the assembled state;
the new sortation module receiving a new IP address corresponding to a position of the new sortation module in the chain of sortation modules.

7. The conveyor assembly of claim 1 , wherein:
the control circuit is configured to communicate with each sortation module to determine the number and relative positions of the sortation modules in the chain with respect to one another.

8. The conveyor assembly of claim 1 , wherein:
the control circuit assigns the sortation destination for the unsorted item to be sorted based on one or more predetermined characteristics of the unsorted item obtained from a merchandise database.

9. The conveyor assembly of claim 1 , further comprising:
a scanner including a scan tunnel or arm positioned above or adjacent an input set of rollers, the control circuit being disposed, at least in part, in the scan tunnel or arm.

10. The conveyor assembly of claim 1 , further comprising:
a non-sortation destination configured to receive an unsorted item that could not be identified by a scanner or that could not be located in a merchandise database.

11. The conveyor assembly of claim 1 , wherein each sortation module comprises a controller configured to divert merchandise items to the at least one sortation destination and configured to receive the IP address corresponding to the sortation module.

12. A method of sorting items comprising:
coupling a plurality of sortation modules to one another to define a chain of sortation modules in an assembled state;
by the plurality of sortation modules, moving and sorting items, each sortation module being configured to divert items to at least one sortation destination;
by a control circuit communicatively coupled to each sortation module:
assigning a unique Internet Protocol (IP) address to each sortation module, each IP address corresponding to a position of each sortation module in the chain of sortation modules when in the assembled state;
determining a sortation destination for an unsorted item to be sorted;
determining a sortation module corresponding to the determined sortation destination; and
instructing the sortation module corresponding to the determined sortation destination to divert the unsorted item to the determined sortation destination.

13. The method of claim 12 , wherein each sortation module comprises a first roller motor control portion and a second roller motor control portion, the method further comprising:
by the first roller motor control portion, causing rotation of at least one roller of a set of rollers in a clockwise direction to divert items to a first sortation destination; and
by the second roller motor control portion, causing rotation of the at least one roller of the set of rollers in a counterclockwise direction to divert items to a second sortation destination.

14. The method of claim 12 , further comprising:
by the control circuit, assigning the unique IP addresses to the sortation modules in ascending or descending sequential order as one proceeds in a direction along the chain of sortation modules.

15. The method of claim 12 further comprising:
reassembling the plurality of sortation modules to different relative positions in the chain of sortation modules than in the assembled state; and
by the control circuit, assigning a new IP address to each sortation module depending on a new position of each sortation module in the chain of sortation modules.

16. The method of claim 12 further comprising:
replacing one of the plurality of sortation modules in the chain of sortation modules with a new sortation module; and
by the new sortation module, receiving a new IP address corresponding to a position of the new sortation module in the chain of sortation modules.

17. The method of claim 12 , further comprising:
by the control circuit, communicating with each sortation module to determine the number and relative positions of the sortation modules in the chain with respect to one another.

18. The method of claim 12 , further comprising:
by the control circuit, assigning the sortation destination for the unsorted item to be sorted based on one or more predetermined characteristics of the unsorted item obtained from a merchandise database.

19. The method of claim 12 , further comprising:
receiving, at a non-sortation destination, an unsorted item that could not be identified by a scanner or that could not be located in a merchandise database.

20. A system for receiving and sorting items shipped to shopping facilities, the system comprising:
a shopping facility containing a plurality of items;
a delivery of items received at the shopping facility; and
a conveyor assembly at the shopping facility, the conveyor assembly comprising:
a plurality of sortation modules configured to move and sort items, wherein each sortation module is configured to dive
