A system is provided for arranging articles in a predetermined sequence. In mail handling applications, the documents destined for local distribution may be segregated as to the respective routes of the postmen and arranged in sequence within each route in accordance with the mail-stops or street addresses. In such a system, the documents are transported by individual mechanical carriers. Temporary high density storage of the documents is provided by a recirculation buffer subsystem. Based upon system priorities, selected carriers may be taken out of buffer storage, independently of the other carriers. The selected carriers are then circulated in a short transit-time loop from which they exit to one or more output racks, where they appear in sequential order.

System for sequencing articles including mail

The present disclosure involves a system for storing and processing articles such as mail flats which cannot be processed on standard letter mail equipment. The system includes mechanical carriers for transporting and remaining with the articles throughout the processing cycle. A recirculation buffer subsystem provides temporary high density random storage which dynamically allocates the system output resources through computer control. In the buffer, the destination-encoded carriers are kept continuously moving in a closed serpentine path. Based upon system priorities, selected carriers may be taken out of buffer storage independently of the other carriers and the former reassigned to output accumulation racks where they remain until outputted from the system. The recirculation buffer subsystem provides a balance between system input and output, thereby substantially improving efficiency and providing savings in cost and space requirements.
