| 摘要 |
A self-timing automatic conveyor system including a low-friction conveyor belt, a holding mechanism actuatable to open and close for selectively controlling flow of goods along a conveyor belt; a control sensor circuit including a first sensor proximate the conveyor belt and adjacent the holding mechanism for monitoring the flow of goods along the conveyor belt to the holding mechanism; a transfer sensor circuit including a second sensor spaced downstream from the first sensor and proximate the conveyor belt for monitoring the flow of goods along the conveyor belt released by the holding mechanism; first gating means, enabled by the control sensor circuit upon the presence of goods at the position of the first sensor and by the transfer sensor upon the passing of goods released during the previous cycle of operation by the holding mechanism, for actuating the holding mechanism to the open condition to pass goods upon receipt of an external signal; and second gating means enabled by the transfer sensor circuit upon the passing of goods released by the holding mechanism, for actuating the holding mechanism to the closed condition.
