A conveyor system comprising guide rails for a plurality of each of dogs which are provided with a driving motor so as to be individually driven along the guide rail. The dogs releasably connected to load carrier vehicles so as to pull these vehicles along between loading stations and unloading stations in which the vehicles may be released from the dogs. A spacing control arrangement is provided for maintaining sufficient spacing between consecutive vehicle loaded dogs according to the space requirements of the vehicles. The spacing control arrangement is rendered inoperative between an idle dog and the foregoing or following dog so as to enable an idle dog to catch up with a foregoing dog or to be caught up by a following dog. The system is well suited for automatic sorting conveyors, since the individually movable dogs may be guided over rail switches to any desired unloading station. |
