  • Patent number: 6979793
    Abstract: To provide a mail sorting and distributing transfer system, which extends transformable time of mail fed from a mail charging line so that the mail can be timely, reliably transferred to conveyor baskets on a mail sorting line, there is a mail sorting and distributing transfer system in which transfer timing levers maintain the receipt ports of transfer baskets provided on an outer circumferential edge of a sorting and distributing turntable in a state where the receipt ports of the transfer baskets are in registry with a mail charging line during the receipt of mail and where the lever pivots so it moves the associated transfer basket. Underlying conveyor baskets on a mail sorting line are moved parallel to and in synchronization with the transfer baskets during the transfer of the mail. The lever is pivoted about an axis parallel to the axis of the mail sorting and distributing turntable.

  • Patent number: 6897395
    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.

  • Patent number: 5096047
    Abstract: A basket for a basket conveyor comprising a plurality of bottom-opening baskets is disclosed. The basket is characterized in that side plates thereof spread upwardly so as to enlarge the article receiving opening sidewardly. The internal walls of the basket may be provided with projections so as to enable smooth discharging of the articles when the bottom cover is opened. Moreover, complimentary projections and channels may be provided to the edge of the article discharging port and the upper surface of the bottom cover respectively in the direction of opening and closing of the bottom cover to prevent jamming of the sorted articles.
