Abstract

A system and method are disclosed for sorting mail pieces that may include both standard and higher class mail. The mail pieces are for delivery to various addresses, and the present invention postpones delivery to some addresses if those addresses are receiving insufficient mail. According to this method, data is collected about each mail piece, and that data for each mail piece is associated with a respective holder that holds the mail piece. Mail is withheld from immediate delivery if the collected data associated with the holder indicates that the mail piece is standard class having a non-immediate delivery deadline, provided that the collected data associated with other holders indicates that there are no other pieces having the same address and having either a higher class or an immediate delivery date.

Claims

1. A sorting system for sorting a plurality of mail pieces that include standard class mail pieces and higher class mail pieces, the plurality of mail pieces being for delivery no earlier than an initial delivery date by carriers from a postal facility to final destination addresses, comprising:

means for collecting data about each of the plurality of mail pieces including data concerning the class of the mail piece and a latest delivery date if the class of the mail piece is standard class;

a plurality of holders, each holder dimensioned for receipt of one mail piece;

means for creating an association of the collected data concerning each mail piece with the respective one of the plurality of holders into which the mail piece is loaded;

withholding means, for withholding a mail piece from delivery on the initial delivery date to a final destination address, if the collected data associated with the respective holder indicates that the mail piece loaded in the respective holder is a standard class mail piece having a latest delivery date after the initial delivery date, provided that the collected data associated with the plurality of holders indicates that there are no other of the plurality of mail pieces addressed to the same destination address as said standard class mail piece and having either a higher class than standard class or having a latest delivery date on or before the initial delivery date; and

a sorter for sorting the mail pieces that are not withheld based upon the collected data associated with each of said holders, so that the mail pieces are sorted according to their final destination addresses.

2. The sorting system of claim 1, wherein the withholding means is for withholding a mail piece contingent upon there being less than a threshold number of the standard class mail pieces destined for said destination address.

3. The sorting system of claim 1, wherein the sorting is performed on the initial delivery date.

4. The sorting system of claim 1, further comprising:

unloading means for unloading the sorted mail pieces that are to be delivered on the initial delivery date into mail trays;

wrapping means for wrapping the unloaded sorted mail pieces for delivery to each respective one of said final destination addresses, with a separate wrapper; and

printing means for printing delivery information on each wrapper.

5. The sorting system of claim 4, wherein the delivery information indicates if there are any mail pieces external to the wrapped mail pieces that need to be delivered to the respective one of said final destination addresses.

6. The sorting system of claim 4, wherein the delivery information indicates how many mail pieces external to the wrapped mail pieces need to be delivered to the respective one of said final destination addresses.

7. The sorting system of claim 1, wherein the withholding means keeps the withheld mail pieces in their respective holders for sequence sorting at a later time.

8. The sorting system of claim 1, wherein the withholding means outsorts the withheld mail pieces from their respective holders for sequence sorting at a later time.

9. The sorting system of claim 1, wherein the withholding means further withholds the standard class mail piece from delivery, provided that the collected data associated with the plurality of holders indicates that there are no parcels addressed to the same destination address as said standard class mail piece.

10. The sorting system of claim 1, wherein the collecting means collects data about parcels for delivery on an initial delivery date from a database separate from the sorting system.

11. The sorting system of claim 1, wherein the withholding means outsorts the withheld mail pieces without loading them into one of the holders.

12. A method for sorting a plurality of mail pieces that include standard class mail pieces and higher class mail pieces, the plurality of mail pieces being for delivery no earlier than an initial delivery date by carriers from a postal facility to final destination addresses, comprising:

collecting data about each of the plurality of mail pieces including data concerning the class of the mail piece and a latest delivery date if the class of the mail piece is standard class;

loading each mail piece in a holder and associating the collected data concerning each mail piece with the respective one of the plurality of holders into which the mail piece is loaded;

withholding a mail piece from delivery on the initial delivery date to a final destination address, if the collected data associated with the respective holder indicates that the mail piece loaded in the respective holder is a standard class mail piece having a latest delivery date after the initial delivery date, provided that the collected data associated with the plurality of holders indicates that there are no other of the plurality of mail pieces addressed to the same destination address as the standard class mail piece and having either a higher class than standard class or having a latest delivery date on or before the initial delivery date; and

sorting the mail pieces that are not withheld based upon the collected data associated with each of said holders so that the mail pieces are sorted according to their final destination addresses.

13. The method of claim 12, wherein the withholding step is contingent upon there being less than a threshold number of the standard class mail pieces destined for said destination address.

14. The method of claim 12 wherein the method is performed on the initial delivery date.

15. The method of claim 12, further comprising:

unloading the sorted mail pieces that are to be delivered on the initial delivery date into mail trays;

wrapping the unloaded sorted mail pieces, for delivery to each respective one of said final destination addresses with a separate wrapper; and

printing delivery information on each wrapper.

16. The method of claim 15, wherein the delivery information indicates if there are any mail pieces external to the wrapped mail pieces that need to be delivered to the respective one of said final destination addresses.

17. The method of claim 15, wherein the delivery information indicates how many mail pieces external to the wrapped mail pieces need to be delivered to the respective one of said final destination addresses.

18. The method of claim 12, wherein the withholding step keeps the withheld mail pieces in their respective holders for sequence sorting at a later time.

19. The method of claim 12, wherein the withholding step outsorts the withheld mail pieces from their respective holders for sequence sorting at a later time.

20. The method of claim 12, wherein the withholding step outsorts the withheld mail pieces before the withheld mail pieces can be loaded into one of the holders.
