Sorting system
First Claim
1. A method for sorting a plurality of items, to each of which a sequence number is assigned, into a predetermined sorted sequence using a plurality of sorting regions, including for each sort, at least one initial sorting regions, and least two additional sorting regions, at least one of the additional sorting regions functioning as a return region, the items being initially located, in an unsorted order, in the at least two initial sorting regions, the method comprising the acts of:
- sorting the items in each at least one initial sorting regions into at least one intermediary sorted set, in which the items are in a sorted order, by moving at least some of the items in the at least one initial sorting regions between the at least one initial sorting region and at least two of the additional sorting regions, such that two items from different initial sorting regions are sorted into the same intermediary sorted set, and by moving at least some of the items between positions in the at least two additional sorting regions; and
sorting the items within each intermediary sorted set by moving at least some of the items to the return region in substantially the predetermined sorted sequence.

Abstract
A system and method are provided for sorting a plurality of items into a predetermined sorted sequence. Items are initially located on initial sorting regions of a sorting apparatus. The items are then sorted into at least one intermediary sorted set and then sorted, from the intermediary sorted sets, into the final sorted sequence. A computer may be used to track the position of the items on the sorting apparatus and to control the movement of the items into the sorted sequence.

9. An apparatus for sorting a plurality of postal bins comprising:
-
a plurality of sorting regions, wherein the plurality of sorting regions comprise for each sorting at least two initial regions in which postal bins are initially located in an unsorted order, and at least two additional sorting regions, at least one of the additional sorting regions functioning as a return region in which postal bins are located after completion of sorting; a first mechanism for physically moving at least one item between at least two selected sorting regions, where the first mechanism is configured to move two postal bins initially located in different initial regions into the same additional region; a second mechanism for physically moving at least one item between positions within each sorting region; a postal bin location tracking mechanism; and controls operative for controlling the first and second mechanisms to move the postal bins into a predetermined sorted sequence by sorting the postal bins in each of the at least two initial sorting regions into at least one intermediary sorted set, in which the postal bins are in a sorted order, by moving postal bins in at least one of the initial sorting regions between the at least one initial sorting region and at least two of the additional sorting regions, such that two postal bins from different initial sorting regions are sorted into the same intermediary sorted set, and sorting the postal bins within each of the at least one intermediary sorted sets by moving at least some of the postal bins to the return region in substantially the predetermined sorted sequence. - View Dependent Claims (10, 11, 12)
