ABSTRACT:
A buffer system for the temporary separate storage of flat articles such as letters for sorting, video coding or other postal processing, uses a buffer which acts as a mechanical RAM and contains a number of storage pockets for separate storage of articles. A conveyance system is provided by elastic clamping on an endless conveyor. The conveyance system is separately controllable in the storage pockets as a letter catchment, retainment and ejection device. Buffers are situated along a branching feed section. Letter logging signals are transmitted for every letter conveyed along the feed section and run in parallel with the branched feed section. These signals in all cases include a letter identification code assigned when the letter is fed into the system. At that stage an application control continuously makes a selection of letters which are eligible for discharge from the system. The system can readily be equipped either as a sorting system or as a video coding system.
