<p>PURPOSE:To have effective operations by coordinating the fore-and-aft relative position of the front part of a carrier with its rear part, changing the fore- and-aft distance between a sensed member for the inter-car distance control and sensor of an inter-car distance control means, and thereby adjusting dispersion of the operation time depending upon the type of car. CONSTITUTION:If a photo-electric switch 50 is off and another 51 is on, the tail of a sensed member 48 of a foregoing carrier 3 lies between them 50, 51 and the inter-car-distance is within the set range, so that the carrier 3 is allowed to run at the set speed so as not to change the inter-car distance. If the photo-electric switch 51 is off and the other 52 is on, by contrast, the inter-car distance is too small being out of the set range, so that the carrier 3 is decelerated from the set speed so that the inter-car distance will enlarge. When the photo-electric switch 52 is turned off, the inter-car distance is very small, so that the carrier 2 is stopped.</p> |
