Abstract

A conveyor system for conveying and/or sorting articles includes an endless track assembly having a conveying path and a plurality of cartridges for receiving articles and discharging the articles. The cartridges are supported from the track assembly and moveable along the conveying path. The cartridges are configured to move transverse to the conveying path between at least two discharge positions. A method for conveying and/or sorting articles is also provided.

Claims

1. A conveyor system for conveying and/or sorting articles, said conveyor system comprises:

an endless track assembly having a conveying path; and

a plurality of cartridges for receiving articles and discharging said received articles, said cartridges supported from said track assembly and moveable along said conveying path, wherein said cartridges are configured to move transverse to said conveying path between at least two discharge positions.

2. The conveyor system as recited in claim 1, wherein the conveyor system further comprises a plurality of support rails operably configured to allow said cartridges to slideably move between said discharge positions.

3. The conveyor system as recited in claim 2, wherein said plurality of support rails suspend from said track assembly.

4. The conveyor system as recited in claim 1, wherein each of said cartridges comprises at least one compartment.

5. The conveyor system as recited in claim 1, wherein each of said cartridges comprises a discharge gate configured to open to discharge said articles.

6. The conveyor system as recited in claim 1, further comprising a feeder mechanism adapted to insert said articles into said cartridges.

7. The conveyor system as recited in claim 1, further comprising at least two conveyors adjacently located to said track assembly to receive said articles from said cartridges.

8. The conveyor system as recited in claim 7, further comprising a buffer module located between each of said cartridges and said conveyors when said cartridges are in said discharge positions.

9. The conveyor system as recited in claim 7, wherein said conveyors comprise discrete zones for receiving said articles.

10. The conveyor system as recited in claim 1, further comprising a control system for controlling the receiving and discharging of said articles.

11. The conveyor system as recited in claim 10, wherein said control system comprises one or more wires extending from each of said cartridges to provides communication for the receiving and/or discharging of said articles.

12. The conveyor system as recited in claim 1, further comprising a mechanical pusher located adjacent said track assembly to selectively move said cartridges between said discharge positions.

13. The conveyor system as recited in claim 1, further comprising a sliding shoe sorter to selectively move said cartridges between said discharge positions.

14. The conveyor system as recited in claim 1, further comprising a transverse drive mechanism to selectively move said cartridges between said discharge positions.

15. The conveyor system as recited in claim 14, wherein said transverse drive mechanism comprises a cartridge drive belt attached to each of said cartridges.

16. The conveyor system as recited in claim 1, wherein the conveyor system comprises multiple levels having two or more of said track assemblies and said associated plurality of cartridges.

17. The conveyor system as recited in claim 2, wherein the conveyor system further comprises carriage assemblies supporting said cartridges between said track assembly and said support rails.

18. A method for conveying and/or sorting articles, said method comprises:

receiving articles into a plurality of cartridges supported from an endless track assembly and moveable along a conveying path, wherein said cartridges are configured to move transverse to said conveying path between at least two discharge positions;

transporting said articles along said conveying path; and

discharging said articles from said cartridges at a predetermined location.

19. A cartridge for receiving and discharging received articles comprises:

a first support configured to attach to an endless track assembly for movement along a conveying path;

a second support configured to interface with a support rail, wherein said support rail allows said cartridge to slideably move between at least two discharge positions;

at least one compartment for containing articles; and

a discharge gate for discharging said articles from said cartridge at a predetermined location.

20. The conveyor system as recited in claim 19, wherein said cartridge slideably moves between said discharge positions in a direction transverse to the conveying path.

21. The conveyor system as recited in claim 19, wherein said articles located within each of said cartridges are vertically positioned relative to said cartridges.

22. A conveyor system comprising:

an endless track assembly having a conveying path;

a plurality of support rails;

a plurality of carriage assemblies suspended between said track assembly and said support rails; and

a plurality of cartridges for receiving and discharging articles, said cartridges moveable along said conveying path and configured to move transverse to said conveying path by said carriage assemblies between at least two discharge positions along said support rails.

23. The conveyor system as recited in claim 22, wherein each of said carriage assemblies comprise:

a mounting pin operably attached to said track assembly;

a control box assembly;

first and second suspension arms operably attached to said support rail; and

a motor box assembly, wherein said motor box assembly is suspended from said second arm and operably drives said cartridge along said support rail in the transverse direction.
