Coding for Selective Discharge from Overhead Chain Conveyors

Abstract

The paper will give particulars of methods of coding used in conjunction with overhead chain conveyors for selective discharge. An installation is then described for the sorting of mail bags from a storage area into numerous positions where discharge is effected into British Railway Universal Trolleys for transport by rail. After the final loading position, the destination code, which is indicated by a label attached to the mail bag, is keyed into an electronic memory, which in turn activates the selected discharge station at the appropriate time, thereby automatically releasing the bag directly into the appropriate trolley.
