Abstract

A method using a single pass sequencer having a transport system for transporting the mail pieces to a transport system having a first carriage system and a second carriage system with a plurality of holders slidable between the first carriage system and the second carriage system with packaged output. Each of the plurality of holders holding a mail piece of the mail pieces received from the transport system. The method includes assigning a code to: (i) the mail pieces based on the destination information, (ii) the plurality of holders on the first carriage, and (iii) a position on the second carriage which corresponds to the initial sequence and a destination sequence of the mail pieces. The method instructs movement of the plurality of holders from the first carriage to the second carriage based on the code assigned to the mail pieces, the plurality of holders on the first carriage and the position on the second carriage such that when the mail pieces are moved to the second carriage they are in sequential order of delivery destination, ready to be packaged.

Claims

1-15. -15. (canceled)

16. A method for sorting objects based on destination point, comprising:

reading destination information associated with the objects;

placing the objects into separate holders on a first carriage;

assigning each of the separate holders an assignment number associated with the destination information for the objects placed therein;

assigning a final sort order number to unused spaces on a second carriage;

sliding the separate holders between the first carriage and the second carriage based on an alignment of the assignment number and the final sort order number in order to sequentially order the objects based on delivery destination.

17. The method of claim 16, further comprising one of:

(i) initially moving any of the separate holders from the first carriage to the second carriage based on an alignment of the assignment number and the final sort order number without moving either of the first carriage or the second carriage; and

(ii) incrementally rotating the first carriage to align the separate holders with a location on the second carriage based on an alignment of the assignment number and the final sort order number in order to sequentially order the objects on the second carriage while the second carriage remains stationary.

18. The method of claim 16, further comprising dropping the objects from the separate holders now on the second carriage into a packager and sealing the objects into a package based on delivery point destination.

19. The method-of claim 17, further comprising:

determining whether there are additional objects in any of the separate holders for the specific delivery point and, if so, continuing to drop each of the objects into the packager for the specific delivery point;

determining whether there are additional objects for the specific delivery point and, if not, packaging the objects into a package for delivery;

placing the objects in a delivery container;

measuring a thickness of the objects prior to placing in the delivery container to determine when the delivery container is full; and

providing labels on the delivery container.

20. The method of claim 16, further comprising:

placing a packager at a predetermined position with respect to the second carriage such that the objects are unloaded from each of the separate holders of the second carriage in the sequential order into the packager; and

moving each of the separate holders from the second carriage to the first carriage when all of the objects are unloaded to the packager.
