Abstract

A method of sorting and bundling mail for delivery to a plurality of delivery points includes sorting the mail pieces in one or more passes through an automated sorting machine using destination codes associated with the mail pieces that are scanned and stored by a computer so that the mail pieces are ordered such that a final sort to a plurality of locations using at least part of the destination codes will place the mail pieces in delivery order and transferring and feeding the mail pieces to a plurality of bundling machines as a singulated stream and sorting the mail pieces to the bundling machines so that mail pieces having the same destination code are sorted to the same machine where the mail pieces are bundled by destination code for delivery.

Claims

1. A method for sorting and bundling mail pieces for delivery comprising:

a) sorting a batch of mail pieces, each mail piece having a destination code thereon which corresponds to one of a predetermined number of delivery destinations for a carrier delivery route, in a sorting pass using an automated sorting machine which scans and stores each delivery code in a computer memory, the computer further storing the number of mail pieces having the same destination code;

b) outputting the batch of mail pieces from the automated sorting machine in order such that the mail pieces are ordered by delivery destination;

c) transferring the batch of sorted mail pieces to at least one bundling machine; and

d) bundling the mail pieces into bundles for delivery to destinations based upon the number of mail pieces stored by the computer for delivery to each destination.

2. The method of claim 1, wherein each delivery point corresponds to a ZIP+4 code.

3. The method of claim 1 wherein the mail pieces of each batch are sorted using a digit of a destination code.

4. The method of claim 3 wherein the mail pieces of each batch are sorted using selected digits of a destination code.

5. A method for sorting and bundling mail pieces for delivery comprising:

a) sorting a batch of mail pieces each having a destination code thereon which corresponds to one of n predetermined delivery destinations with an automated sorting machine which scans and stores each destination code in a computer memory in a first pass of the mail pieces through the sorting machine, the automated sorting machine ordering the mail pieces according to a first selected destination criteria; and

b) sorting the batch of mail pieces to a plurality of b bundling machines by destination code whereupon mail pieces having the same destination code are directed to one of the bundling machines and bundled together in the bundling machine.

6. The method of claim 5 further comprising mail pieces are sorted with the automated sorting machine in a plurality of passes through the machine.

7. The method of claim 6 further comprising transferring a batch of partially sorted mail pieces from the automated sorting machine to a feeder after the plurality of sorting passes is completed.

8. The method of claim 7 further comprising feeding the batch of partially sorted mail pieces with the feeder to the plurality of bundling machines.

9. The method of claim 5 wherein the automated sorting machine sorts the mail pieces to m bins in a plurality of p sorting passes and wherein the number of bundling machines used to bundle the mail pieces is greater than or equal to n divided by the quantity m raised to the power p.

10. The method of claim 5 wherein the mail pieces of each batch are sorted using a digit of a destination code.

11. The method of claim 5 wherein the mail pieces of each batch are sorted using selected digits of a destination code.

12. The method of claim 11 wherein the destination code comprises a ZIP code plus additional digits, the destination code identifying a specific delivery point.

13. The method of claim 5 where the n predetermined delivery destinations are delivery points on a carrier delivery route.

14. The method of claim 13 further comprising delivering the bundled mail to the delivery points.

20. The method of claim 13 further comprising delivering the bundled mail to the delivery destinations.

15. A method for sorting and bundling mail pieces for delivery comprising:

a) sorting a batch of mail pieces each having a destination code thereon which corresponds to one of n predetermined delivery destinations in a carrier delivery route with an automated sorting machine which scans and stores each destination code in a computer memory in a first pass of the mail pieces through the sorting machine, the automated sorting machine sorting the mail pieces to a plurality of m bins using a first selected criteria corresponding to at least part of a code identifying a delivery destination in the first pass;

b) sorting the mail pieces in at least one additional sorting pass through the automated sorting machine, the automated sorting machine using a different selected criteria corresponding to at least part of a code identifying a delivery destination in each additional sorting pass;

c) transferring the mail pieces to a plurality of bundling machines, the batch of mail pieces being partially ordered by destination code such that a final sort to b locations using at least part of a code identifying a delivery destination will place the mail pieces in delivery order;

d) sorting the mail pieces to at least b of the bundling machines using a selected criteria corresponding to at least part of a code identifying a delivery destination whereupon mail pieces having the same destination code are directed to one of the bundling machines and bundled together in the bundling machine.

16. The method of claim 15 wherein the part of the code used to sort the mail pieces to the bundling machines is different from the parts of the code used to sort the mail pieces in steps a) and b).

17. The method of claim 15 wherein the destination code comprises a ZIP code plus additional digits, the destination code identifying a specific delivery point and wherein the first and additional sorting passes sort the mail pieces according to one or more selected digits of the code.

18. The method of claim 15 wherein the destination code comprises a ZIP code plus additional digits, the destination code identifying a specific delivery point and wherein the mail pieces are sorted to the bundling machines according to one or more selected digits of the code not used in the sorting passes.

19. The method of claim 15 further comprising scanning the mail pieces and reading a destination code as the mail pieces are sorted to the bundling machines.
