Subsequently, the bulk cargo loaded on the conveyance barge 30 is supplied to the second variable conveyor 41 mounted on the barge line 40 by the forklift. Accordingly, the second variable conveyor 41 of the applied barge 40 is controlled to be movable in the right and left direction and the upward and downward direction, and the bulk cargo is loaded on the main line 50 for delivery.

In the conventional shore vest goods shipping system using the barge as described above, the shipment of the bulk cargo is sequentially progressed by the transit transportation of the transporting barge line 30 and the loaded barge line 40, In particular, since the second variable conveyor 41 of the loaded barge 40 repeatedly ascends and descends at both ends at every stage for loading and transferring the bulk cargo, the loading time and the shipping cost There is a problem that the shipping efficiency is lowered.

In addition, since the second variable conveyor 41 of the line barge 40 has a limited range of variable movement in the left and right direction and the up and down direction, there is a problem that the shipping time and shipping cost are increased and the shipping efficiency is lowered.

In addition, in the second variable conveyor 41 of the line barge 40, bulk cargo is shipped so that the bulk cargo is evenly spread through a chute (not shown) And the like.

A belt conveyor 21 for conveying the bulk cargo is provided between the wharf yard 10 and the bridge portion 20 and a bulk cargo is relayed to the bridge portion 20 by the conveying barge 30 Since the first variable conveyor 22 for loading the shipment is provided, the shipping time due to the stepwise relaying is increased, and the shipping cost due to the increase of the relaying equipment is increased, which inevitably lowers the shipping efficiency.

Therefore, in the shipping system of bulk cargo using the conventional barge, there is a desperate need for a shipping method and a countermeasure to improve the shipping efficiency by shortening the shipping time and reducing the shipping cost through prompt shipment process.
