Patent Issued for Method and Apparatus for Sorting of Items in Two Sorting Processes

摘要

"U.S. patent publication No. 20060283784 A1 discloses that postal items or other items be first of all presorted, for example into different classes, which are defined by the dimensions of the postal items. A sorting installation for the first class ('letters', that is to say standard letters) sorts the postal items in this class in accordance with a predetermined destination point sequence. The postal items in the second class ('flats', that is to say large letters) are likewise sorted, and in the process are mixed with the postal items in the first class. In one embodiment, the postal items in the first class are sorted in two sorting runs ('two-pass sorting'). A first sorting run is carried out for the postal items in the second class. Sorted stack elements of standard letters are mixed with the large letters in a second sorting run. In this case, the stack elements are introduced between a flow of large letters.
