Generally, wood chips used as raw materials for papermaking are transported to a dock by a main line and then subjected to predetermined loading and unloading operations through equipment such as a crane.

In this case, a conveyor is usually used as a method for transporting freight from the ship to the yard. Conventionally, a cargo transfer device using such a conveyor has been previously filed as a Korean Registered Patent No. 10-1076205 (Published on October 24, 2011).

A method of transferring a wood chip using such a conventional transfer device will now be described in detail.

First, when the main ship loaded with wood chip cargo arrives at the unloading dock, the wood chip cargo discharged through the discharge port of the unloading unit provided on the main line is dropped onto the apron yard using the conveyor equipment. Then, the dropped wood chips are transferred to the dump trucks using equipment such as a payloader, and transported to the designated yard, and the transferred wood chips are taken down to the yard. Finally, the wood chips are stacked horizontally at a constant height using a payloader and an excavator.

Specifically, the main conveyor unit 300 removes the wood chip cargo dropped on the apron from the conventional conveying system using the equipment such as the payloader and the dump truck, and controls the conveyor 310 and the transformer towers 321 and 322 To efficiently transport the wood chip cargo to the yard yard Y1.

As shown in FIG. 7, the swing tower unit 400 includes a swinging tower unit 400, which is disposed at an end of the main conveyor unit 300, It is possible to turn 360 degrees. The swing tower unit 400 is turned in 12 steps in total. That is, it is turned by 30 degrees in the first step. As a result, the field interval can be adjusted to about 1 m and the yard field Y1 can be efficiently used.

 8, the swing tower unit 400 is installed to be rotatable up and down at an angle of 90 degrees, and the wood chip cargo is raked to a desired height in the yard field Y1. In this case, the end portion of the swing tower unit 400 can be positioned as close as possible to the field ground plane, thereby minimizing the generation of scattered dust when unloading the wood chip cargo.

Referring to FIG. 9, the swing tower unit 400 is extended in the longitudinal direction so that the field Y1 can be widely used. Specifically, the swing tower unit 400 includes a first conveyor 410 for receiving the wood chip cargo conveyed in the first direction and receiving the power and conveying the wood chip cargo to a predetermined height, and a second conveyor 410 on the leading rail 421 of the first conveyor 410 And a second conveyor 420 installed to be slidable and extendable to selectively extend the entire length.

In another embodiment, the swing tower unit 400 includes the second conveyor 420 installed at the tip of the first conveyor 410 so that the hinge shaft is pivotable about its center of rotation, You can expand the total length when expanded.

By using the swing tower unit 400 having such a structure, the wood chip cargo can be stacked up to a height of 15 m. In addition, by using the expansion means, it is possible to maximize the sky area per unit area.

Referring again to FIG. 1, the sub conveyor unit 500 is installed at a lower dropping point of the second discharge port 120 to transport the wood chip cargo discharged to the yard field Y2 at a predetermined position (shortest distance). In this case, the wood chips stored on the yard Y2 through the sub-conveyor unit 500 are transported to a predetermined position by using equipment such as a payloader and a dump truck as in the conventional method.
