ABSTRACT:
The invention aims to provide a zone controlled conveyor system including a plurality of zones for control. A zone controlled conveyor system, while conveyance of any article from a zone to a downstream zone is forbidden, (a) starts operation of a driving roller in the zone at a first conveying speed slower than a prescribed standard conveying speed upon detection of a presence of an article from an immediately upstream zone of the zone, (b) operates the driving roller at a second conveying speed slower than the first conveying speed after arrival of the article at a predetermined position in the zone, and (c) halts operation of the driving roller upon detection of a presence of the article in the zone. Thereby, the system enables to stop articles at a target position accurately.
