Mail sorter

Abstract

A mail sorter, which can reliably sort mail while avoiding the breakage and the recovery mistake of mail released from conveyor baskets, which move on the mail sorting line in circulation. The mail sorter has a conveyor line with a conveying forward run and a conveying return run closely arranged back to back with each, and layered mail recovery box groups are disposed along a lower region of the conveying return run in parallel to each other. The mail recovery box groups comprise lowest stage boxes for recovering mail M released from conveyor baskets on the conveying forward run through a transverse deflection chute, middle stage boxes for recovering mail M released from the conveyor baskets on the conveying forward run through a discharge chute, and uppermost stage boxes for recovering mail M released from the conveying baskets on the conveying return run through a buffer chute.
