PURPOSE:To prevent transported objects from being overlapped in doughboys by sensing load existence of each type of objects at least at two points, and by equipping a loading type conveyor with a load-exist sensor which emits signals. CONSTITUTION:Objects are transported by a conveyor to a downstream stopper. If at this time the interval of ONs of load existence sensors at 12, 13 is within a specified time, the operation shall be continued. In case the load existence sensor 13 is not actuated (ON) within the specified time of actuation of the load existence sensor 12, a loading type conveyor 5 is operated until the load existence sensor 13 is actuated, while the loading type conveyor 1 is held at a standstill, and the objects are put in contact with the left and right stoppers 10, 11 and delivered to a transport roll 14 etc. using a kicker etc. In case the loading type conveyors 1, 5 are operated simultaneously, incoordination of the speeds of two conveyors 1, 5 may produce a new skew, so that a clutch 9 is used to provide synchronization.
