Abstract

A high throughput sorting device is disclosed. The device includes a first sorter and a second sorter, each of the first and second sorters having a plurality of cells each configured to support, carry, and deposit an item. The device can also include at least one shared chute extending below a portion of the first sorter and a portion of the second sorter. The at least one chute can be configured to receive an item deposited by each of the plurality of cells and transport the item to an endpoint. The device can also include a base configured to support the at least one shared chute and the first and second sorters.

First claim

What is claimed is:

1. A high throughput sorting system, comprising:
a first sorting section parallel to a second sorting section, the first sorting section and the second sorting section comprising a plurality of cells, each cell including a platform, the platform comprising a pair of doors configured to:
support an item when the pair of doors are in a closed configuration, and
deposit the item from the cell when the pair of doors are in an open configuration;

a plurality of chutes, each chute extending below the first sorting section and the second sorting section, the plurality of chutes configured to receive items deposited through the plurality of cells and to transport the items to a plurality of sorting destinations;
a first inductor positioned to feed the item into one of the plurality of cells in the first sorting section;
a database configured to record a sorting destination for the item and associate the sorting destination with the one of the plurality of cells containing the item; and
a controller configured to open the one of the plurality of cells containing the item when positioned over one of the plurality of chutes corresponding to the sorting destination of the item.

2. The system of claim 1 , further comprising an imaging system configured to:
capture an image of the item, the image comprising intended destination information for the item;
determine an intended destination for the item based on the captured image; and
identify a sorting destination from the plurality of sorting destinations for the item based on the determined intended destination.

3. The system of claim 1 , wherein the sorter further comprises an encoder configured to monitor a position of each of the plurality of cells relative to the plurality of chutes.

4. The system of claim 1 , wherein each of the plurality of cells comprises a sensor configured to determine whether the particular cell contains an item.

5. The system of claim 1 , further comprising a second inductor positioned to feed a plurality of items into the plurality of cells in to the second sorting section.

6. The system of claim 1 , wherein the pair of doors comprise a leading door with having a first length and a trailing door having a second length.

7. The system of claim 6 , wherein the second length is less than the first length.

8. The system of claim 1 , wherein a combined length of the first length and second length makes up substantially the total length of one of the plurality of cells.

9. The system of claim 8 , wherein the second length is from 10 percent to 50 percent of the total length of the one of the plurality of the cells.

10. The system of claim 8 , wherein the second length is from 25 percent to 35 percent of the total length of the one of the plurality of the cells.

11. The system of claim 1 , further comprising a plurality of bins associated with the plurality of sort destinations.

12. The system of claim 11 , wherein the plurality of bins comprises a first plurality of bins disposed at least partially below the first sorting section and a second plurality of bins disposed at least partially below the second sorting section.

13. The system of claim 12 , wherein the plurality of chutes are configured to direct the received item to one of the first plurality of bins or one of the second plurality of bins.

14. The system of claim 12 , wherein the plurality of chutes are configured such that the controller can direct the item to one of the first plurality of bins or to one of the second plurality of bins by opening one of the plurality of cells in either the first sorter section or the second sorter section.
