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 method of high throughput sorting, comprising:
placing, by a first inductor, a first item onto a first cell in a first section of a sorter;
placing, by a second inductor, a second item onto a second cell in a second section of the sorter, wherein the first and second sections of the sorter are disposed parallel to each other;
associating the first cell with the first item in a memory;
associating the second cell with the second item in the memory;
scanning the first and second items to read first and second destination information located on the first and second items;
determining a first delivery destination for the first item and determining a second delivery destination for the second item based on the read first and second destination information;
determining sort destinations for the first item and for the second item based on the determined delivery destinations;
associating the first cell and the second cell with the sort destination in the memory;
moving the first cell along the sorter to a first location positioned over a chute leading to the sort destination;
depositing the first item onto the chute from the first cell at the first location such that the chute guides the first item to the sort destination;
moving the second cell along the sorter to a second location positioned over the chute, the second location being different from the first location; and
depositing the second item onto the chute from the second cell at the second location such that the chute guides the second item to the sort destination.

2. The method of claim 1 , wherein a first portion of the chute is disposed under the first location of the sorter to receive items from the first cell, and a second portion of the chute is disposed under the second location of the sorter to receive items from the second cell, wherein the first and second portions of the chute are continuous, and the chute is disposed under the first and second locations of the sorter at an angle in order to guide the first and second items to the sort destination.

3. The method of claim 1 , wherein determining the first and second delivery destinations comprises imaging the first item to read a delivery point there and imaging the second item to read a delivery point thereon.

4. The method of claim 1 , further comprising sensing, via a sensor of the first cell, the presence of the first item in the first cell and sensing, via a sensor of the second cell, the presence of the second item in the second cell.

5. The method of claim 1 , further comprising associating the sort destination with the first location.

6. The method of claim 1 , wherein in the portions of the first and second sections of the sorter that are disposed section of the sorter are configured to move the first and second cells in parallel and opposite directions.

7. The method of claim 1 , wherein the first location and second location are located in the portions of the first and second sections that are disposed parallel to each other.

8. The method of claim 1 , wherein the sort destination comprises a bin, wherein the method further comprises, directing, via the chute, the first item to the bin disposed at the sort destination.
