System and method for grouping mail pieces in a sorter

1. A method for sorting media items, comprising the steps of:

feeding a series of media items onto a transport path for sortation into two or more sortation bins, said transport path including a controllable separator operable to separate media for transport on said transport path;

accumulating sequential media items having similar information into groups, the accumulation step, furthermore, grouping media items along the transport path in an on-edge layered format, and

controlling said separator such that groups of media items destined for the same sortation bin are transported along said transport path to said same sortation bin; and,

controlling said separator such that adjacent media items destined for the different sortation bins are separated for separate transport along said transport path to said different sortation bins, and

wherein the order of said media items within groups created by said separator system is controlled such that subsequent sortation of groups of media items will further differentiate said media items by media item order sequence of media items in each of said groups of media items,

wherein said media items group controlled order is a media item delivery order sequence, and

wherein the said media items group controlled order is determined by the position of the specific destination sortation bin with respect to the transport path of said transport system.

2. The method for sorting media items as defined in claim 1 comprising the further step of:

controlling said separator system to limit the thickness of each group of media items destined for said same sortation bin not to exceed a predetermined thickness and to separate and feed onto said transport system any subsequent media items destined for said same sortation bin which would cause said group of media items to exceed said predetermined thickness.

3. A method for sorting mail pieces by a separator system, comprising the steps of:

feeding a plurality of mail pieces onto a transport system along a transport path for sortation into sortation bins;

accumulating sequential media items having similar information into groups, the accumulation step, furthermore, grouping media items along the transoort path in an on-edge layered format, and

controlling said separator system to mail pieces destined for the same sortation bin onto said transport system for transport to said same sortation bin; and,

controlling said separator system feed mail pieces destined for a different sortation bin onto said transport system as sequential a mail pieces are separated from said group of mail pieces to said different sortation bin and

wherein the order of said mail pieces within groups created by said separator system is controlled such that subsequent sortation of groups of mail pieces will further differentiate said mail piece by mail piece delivery order sequence and wherein said mail piece group controlled order is a mail piece delivery order sequence and each group order is in front to back delivery order sequence or a back to front delivery order sequence depending on the specific destination sortation bin for said group of ordered mail pieces.

4. The method for sorting mail pieces as defined in claim 3 wherein the said mail piece group controlled order is determined by the position of the specific destination sortation bin with respect to the transport path of said transport system.

5. A method for sorting mail pieces by a separator system, comprising the steps of:

feeding a plurality of mail pieces onto a transport system along a transport path for sortation into sortation bins;

accumulating sequential media items having similar information into groups, the accumulation step, furthermore, grouping media items along the transport path in an on-edge layered format, and

controlling said separator system to feed mail pieces destined for the same sortation bin onto said transport system for transport to said same sortation bin; and,

controlling said separator system feed mail pieces destined for a different sortation bin onto said transport system as sequential a mail pieces are separated from said group of mail pieces to said different sortation bin and and

wherein said mail pieces are transported on said transport system in a mail piece carriers to provide escorted transport for said mail pieces to said sortation bins,

wherein the order of said mail pieces within groups created by said separator system is controlled such that subsequent sortation of groups of mail pieces transported in said plurality of mail piece carriers to said sortation bins will further differentiate said mail piece by mail piece delivery order sequence and wherein the said mail piece group controlled order is determined by the position of the specific destination sortation bin with respect to the transport path of said transport system.
