Abstract

A system and method for feeding and sorting mail pieces, and for moving the mail pieces to sorter bins according to delivery information on the mail pieces, includes a plurality of feeders, and a plurality of sorters configured to receive and sort the mail pieces from the feeders. A separating mechanism is configured to separate the feeders from the sorters in order to provide a plurality of pathways, so that each of the feeders is connectable by pathways to substantially all of the sorters. Each sorter includes sorter bins, and each sorter bin receives a subset of the mail pieces. Also included is a mechanism for selecting the pathways according to the delivery information read from each of the mail pieces.

Claims

1. A sorting system, for feeding and sorting mail pieces, and for moving the mail pieces to sorted mail stations according to delivery information on the mail pieces, the system comprising:

a plurality of feeding stations, each of the feeding stations having means to singulate mail pieces and to read the delivery information thereon;

a plurality of sorters configured to receive and sort the mail pieces from the plurality of feeding stations; and

a plurality of pathways;

wherein each one of the feeding stations is connectable by pathways to substantially all of the plurality of sorters;

wherein each of the plurality of sorters has a plurality of the sorted mail stations, each of the sorted mail stations dimensioned for receiving a subset of the mail pieces according to the delivery information, and

wherein the system further comprises means for selecting the pathways according to the delivery information read from the mail pieces.

2. The sorting system of claim 1, wherein the system further comprises:

a plurality of clamps, each clamp dimensioned for receipt of at least one of the mail pieces;

means for placing the mail pieces into respective clamps;

means for creating an association between the delivery information of each mail piece and its respective clamp; and

means for moving the clamps which hold the mail pieces to a respective sorter and sorted mail station, based upon the association of each clamp with the delivery information.

3. The sorting system of claim 2, further comprising means for opening the sorted clamps to release the mail pieces.

4. The sorting system of claim 1, wherein the sorting system has means for moving one of the mail pieces singulated at one of the feeding stations to any of the sorted mail stations of any of the sorters.

5. The sorting system of claim 1, wherein a first plurality of the sorted mail stations are allocated for a corresponding plurality of respective inbound mail destinations, and a second plurality of the sorted mail stations are allocated for a corresponding plurality of respective outbound mail destinations.

6. The sorting system of claim 1, wherein the pathways are also arranged for moving sorted mail from one of the sorters to another of the sorters, for further sorting.

7. The sorting system of claim 1, wherein at least one of the plurality of feeding stations accepts manual singulation of mail pieces.

8. A method for feeding and sorting mail pieces and for moving the mail pieces from a plurality of feeding stations to sorted mail stations according to delivery information on the mail pieces, the method comprising:

singulating the mail pieces and reading the delivery information thereon, at a plurality of feeding stations;

receiving and sorting the mail pieces at a plurality of sorters; and

wherein each one of the feeding stations is connectable by a plurality of pathways to substantially each of the plurality of sorters,

wherein each of the plurality of sorters has a plurality of sorted mail stations, each of the sorted mail stations dimensioned for receiving a subset of the mail pieces according to the delivery information, and

wherein the method further comprises selecting the pathways according to the delivery information read from the mail pieces.

9. The method of claim 8, wherein the method further comprises:

placing the mail pieces into respective clamps;

creating an association between the delivery information of each mail piece and its respective clamp; and

moving the clamps which hold the mail pieces to a respective sorter and sorted mail station, based upon the association of each clamp with the delivery information.

10. The method of claim 9, further comprising opening the sorted clamps to release the mail pieces.

11. The method of claim 8, wherein the method further comprises moving one of the mail pieces singulated by one of the feeding stations to any selected one of the sorted mail stations of any of the sorters.

12. The method of claim 8, wherein a first plurality of the sorted mail stations are allocated for a corresponding plurality of respective inbound mail destinations, and a second plurality of the sorted mail stations are allocated for a corresponding plurality of respective outbound mail destinations.

13. The method of claim 8, wherein the pathways are also arranged for moving sorted mail from one of the sorters to another of the sorters, for further sorting.

14. The method of claim 8, wherein said singulating step at said plurality of feeding stations includes at least one manual singulation wherein mail pieces are manually inserted into at least one transport path.

15. The method of claim 8, further comprising:

moving sorted mail pieces from a sorted mail station past an unload station;

diverting one or more identified mail pieces into the unload station; and

returning a remainder of the sorted mail pieces back to the sorted mail station.
