Abstract

Embodiments of a system and method for sorting and sequencing articles in a processing facility are disclosed. Delivery endpoints are divided and grouped into stop groups. A first sorter sorts items according to stop group and outputs the items to trays. The output trays from the first sorter are loaded to a second sorter in stop group order. The second sorter can then sort the items into output bins in delivery sequence order.

First claim

What is claimed is:

1. A system for sorting items comprising:
a processor configured to implement a sequencing scheme for a distribution facility;
item processing equipment comprising:
an intake system configured to receive a plurality of items to be sequenced, the intake system comprising a scanner in communication with the processor, the scanner configured to read an intended delivery point on an item;
a sorting portion comprising:
one or more containers; and
a diverter member for diverting the item from the scanning portion into the one or more containers, the diverter member comprising a plurality of selectively moveable components to direct an item along a first path or a second path; and

a storage area located apart from the item processing equipment configured to store the plurality of containers, and wherein the processor is further configured to store the location of the containers within the storage area; and
a container manipulator configured to move the plurality of containers from the item processing equipment and into the storage area according to instructions from the processor and to reintroduce the plurality of containers from the storage area and into the into the intake system of the item processing equipment.

2. The system of claim 1 wherein the scanner is configured identify an intended delivery destination for the item, and the processor is configured to store the identified intended delivery destination for the items.

3. The system of claim 2 , further comprising a memory in communication with the processor, the memory storing a sorting scheme, the sorting scheme including a plurality of delivery destinations corresponding to a plurality of stop groups, wherein each of the plurality of delivery destinations is associated with a stop group, and wherein the processor is configured to identify the stop group associated with the scanned intended delivery destination.

4. The system of claim 3 wherein the processor is configured to control the diverting member to sort the plurality of items into one or more containers according to the stop group associated for each of the plurality of items.

5. The system of claim 3 wherein the processor is configured to control the container manipulator to reintroduce one or more containers into the intake system based on the stop groups of the items in the containers.

6. The system of claim 3 , wherein the items are divided into stop groups based on a scheme, a carrier, and a stop number.

7. The system of claim 1 , wherein the storage area comprise a plurality of shelves, and wherein the container manipulator is configured to be moveable along a guide member in order to place the one or more containers into one of the plurality of shelves in the storage area.

8. The system of claim 1 , wherein the containers comprise computer readable identifiers, and wherein the processor is configured to associate, in a memory, the computer readable code with the contents of the container.

9. The system of claim 8 , wherein the processor is further configured to store, in the memory, the location of the container within the storage area.

10. The system of claim 9 , wherein the location of the container comprises an identifier for the one compartment of the plurality of compartments in which the container is located.

11. The system of claim 7 , wherein the processor is further configured to identify, based on a sort plan, a container having the contents which are to be processed according to the sort plan.

12. The system of claim 11 , wherein the processor is configured to identify the one shelf within the plurality of shelves of the storage area the container having the contents which are to be processed according to the sort plan.

13. The system of claim 12 , wherein the tray manipulator is configured to obtain, from the identified one compartment of the plurality of storage compartments, the container having the contents which are to be processed according to the sort plan.
