Abstract

PURPOSE:To prevent a conveying track from being jammed and enable the conveying power to be improved, by providing an empty conveying car in a standy state in one of the branch tracks selecting a station with a small number of conveying times placed before in the running direction of a station with a large number of conveying times. CONSTITUTION:The method continually provides an emptied conveying car 1a, 1b in a standy state in a station A, F with a small number of conveying times corresponding to a before side in the moving direction of conveying cars 1a-1e moving in the direction of an arrow head along a track 2 of loop shape for a station B with a large number of conveying times. And the method, in which the empty conveying car 1a in the station A near the station B for its conveyance requirement moves to the station B to load a conveyed material to be unloaded in the destination station while the empty conveying car 1b in the station F or a conveying car of the emptied conveying cars in the other station near the station A moves to the station A with an empty car disappearing waits for the next conveyance requirement. Accordingly, the method, preventing the track from being jammed by the empty car on the track, enables the high conveying power to be attained.

In response to a transport request, the vehicle goes to station (3) and loads the goods, goes to station CB> and unloads the goods, and when the car becomes empty, it returns to the waiting zone and waits for the next transport request. Similarly, when transporting objects from the waiting zone to station (5), the transport vehicle loads the objects from the waiting zone to station (5) and moves in the direction of the arrow to station (2a) through track (2a). After unloading the transported items, it returns to the waiting zone again. Conveyance between each station is carried out by constantly repeating such operations.

In the prior art, when a car becomes empty, it always returns to the waiting zone to wait for a transport request, which increases the number of times the empty car moves on the track and lengthens the time it occupies the track. Therefore, congestion occurred on the track, and the time from when a transport request was issued until the actual transport was completed was long, and the transport capacity was limited. If a plurality of standby zones are provided at multiple locations, the space will increase and extra branching sections will be required, which will lengthen the traveling time of the transport vehicle and will not contribute to improving the overall transport capacity.

According to the transport method of the embodiment, the congestion on the track due to empty cars that occurred in the conventional technology is eliminated, and the loss time can be reduced in response to transport requests from stations that have a large number of transports, so the capacity of the entire transport system can be improved. It is possible to achieve a very high general feed capacity. Furthermore, since the number of waiting zones can be reduced, space can be used effectively.・In addition, the place where empty cars wait is not limited to the station, but the same effect can be obtained by having empty cars wait at the bypass (2b) part of the track, as shown in Figure 2. can be obtained.
