Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method and apparatus for loading timber at a loading site of a timber cableway for transporting timber felled in a mountain forest.

Conventional technology Logged trees are long and heavy and difficult to transport as they are, so they are cut into predetermined lengths to make them easier to transport at the logging area. ) 1 to the loading platform 21 using a lumber collecting machine.
After the timber is collected on top of the timber transport cableway 24, the direction of the short timber 23 is corrected by the human power of a worker so that it is almost parallel to the main rope 25 of the timber transport cableway 24. The plurality of short materials 23 whose direction has been corrected are hung on the load line 27 of the carrier 26, and then the plurality of short materials 23 are manually moved from the top of the loading platform 22 to the loading platform 22 and the platform scaffolding 27. The plurality of short materials 23 are suspended between the carrier 2 and the
Loading into 6.

Problems to be Solved by the Invention In this conventional lumber loading method, as shown in Figure 1, the direction of the short pieces of lumber is corrected manually, and the lumber is manually loaded into the carrier 26. Because the logs are loaded onto the logs, it is extremely difficult to manually correct the direction of the long, heavy wood that has been felled (hereinafter referred to as "whole trunk timber") and load it onto a transporter, which is both labor-intensive. There are also drawbacks, such as the fact that the wood gets a lot of scratches and is dangerous when the wood is manually redirected or pulled when loaded onto a carrier.

This invention eliminates these drawbacks of conventional wood loading methods, and allows long and heavy whole-stem timber to be easily transported.
The purpose of this is to allow the wood to be safely loaded onto the transporters of the timber cableway and to reduce the risk of scratches on the wood, such as whole trunks.

Means for Solving the Problems The method of loading wood at the loading area of the timber cableway according to the first invention is as shown in Figs. The entire trunk of timber 9 was placed on two conveyors 4.4 set up, and one of the conveyors 4 was moved forward or backward to correct the direction of the timber 9 so that it was almost parallel to the main rope 2 of the timber cableway. Afterwards, the wood 9 is automatically loaded into the carrier by placing the bronze 11 of the carrier 10 on the wood 9 and moving both conveyors 4.4 forward.

The loading device for lumber in the loading area of the lumber cableway according to the second invention f! ! , is an apparatus for carrying out the method of the first invention, in which conveyors 4, 4 are placed at a predetermined interval in a direction substantially perpendicular to the main rope 2 of the timber transport cableway in the loading area of the timber transport cableway. 2
A stand is provided, and each of the conveyors 4.4 is provided with a regular rotating machine.

By placing whole trunks and other timber on two conveyors installed at intervals in the loading area of the timber cableway, one of the conveyors is moved forward or backward. After hanging the bronze of the carrier on the parallel wood, the operator presses the interlocking advance operation button to move both conveyors forward, allowing the wood to be automatically loaded onto the carrier.

Embodiment Next, one embodiment of the method and equipment for loading timber in the loading area of a timber cableway according to the present invention will be explained with reference to the drawings.

As shown in the loading area IFi 1st prison, three logs 3 are installed behind the main rope 2 of the continuous wooden path at an interval of about 1/3 of the length of the chain conveyor 4, and these 3 logs are Two chain conveyors 4.4' are installed on top of the book log 3 and at a distance of approximately 10 m from the main rope 2 of the lumber transport cableway.

This chain conveyor is 4t! As shown in Figure 4, motors 5 capable of forward and reverse rotation are installed. This motor 5
ii It serves as a power source as well as a forward and reverse rotating machine.

A projection 6 and a rotatable stopper 7 are provided at the rear end of the chain conveyor 4. A platform scaffold 8 necessary for loading work is provided in the loading area 1 using logs.

9 tons of long and heavy whole trunk wood that was cut down in the forest? It is placed on two chain conveyors 4゜4 by a lumber collecting machine (not shown), and when the whole trunk lumber 9 is not parallel to the main rope 2 but is inclined, as shown in Figure 5. Press the operation button to advance one of the chain conveyors 4 on the left side to correct the direction of the entire trunk 9 to be almost parallel to the main rope 2 as shown in Figure 6, and then press another operation button to move forward in conjunction. Push both chain conveyors 4.
4 are moved forward at the same time to transfer all the trunk members 9 to the front ends 4/ and 4/ of the chain conveyor 4.4 as shown in Figure 7.

After the worker places the load tsll of the carrier lO on the entire trunk material 9 that has moved up to the front ends 4/, 4/ of the chain conveyors 4, 4, the operator presses the operation button that moves forward in conjunction with the other chain conveyors 4.4. By moving forward, all the trunk timbers 9 fall from the top of the chain conveyor 4.4 of the loading area 1 into the space between the loading area 1 and the platform platform 8, and fall from the mILN to the third
As shown in the figure, the whole trunk material 9 is automatically loaded into the carrier 10.

In this embodiment, the entire trunk 9 is placed on the chain conveyor 4.
After placing it on the wood collection machine, press the operation button of the chain conveyor 4, and hang the bronze 11 of the carrier 10 on the whole trunk 9.
The long and heavy whole trunk material 9 can be safely loaded onto the carrier IO from a non-dangerous location with extremely light work. Since the distance between the carriers 10 can be increased, the drooping of the main rope 2 due to the load can be reduced.

Since the loading area 1 has a simple structure of just installing two chain conveyors 4 and a board platform scaffold 8, it does not require a conventional large area and sturdy loading board platform and board platform scaffold. Compared to traditional loading docks, loading docks can be set up in a shorter period of time and at lower cost.

Furthermore, the whole trunk timber 9 is transported to the unloading area, and the individual whole trunk timber 9
Depending on the shape (appearance) of the tree, for example, the whole trunk is stocked, bent, knotted, cracked, rotted, and the thickness of the tree is cut into short or long pieces. Furthermore, it is easier to cut whole trunks on the flat ground near the W wholesaler than on sloped forest land or in a narrow loading area. The best wood VC can be cut with just 1 force.

In this embodiment, the platform scaffold 8 is provided on the opposite side of the main rope 2 to the side where the loading area 1 is provided. Feet @8′
If loading work can be done simply by installing a scaffolding, there is no need to install a platform. Although the explanation has been made regarding loading all the trunks one by one, it is also possible to load a plurality of all the trunks depending on the weight of all the trunks. In this case, as shown in FIG. 8, for example, if the directions of all the two trunk members are not constant, the stoppers 7 are engaged with all the protrusions 6, and then both chain conveyors 4.
4 is moved backward to align the two whole trunks as shown in No. 9121, and then both chain conveyors 4゜4 are moved forward and the two whole trunks are transferred to the carrier in the same manner as in the previous embodiment. Push in.

In addition, if the material is made into short materials, Vi1 between the chain conveyor
It is also possible to reduce the size of the material and use it by loading it into a carrier.

Effects of the Invention The method and device for loading timber at the loading area of a timber cableway according to the present invention uses a timber collecting machine to load timber, such as whole trunk timber, onto two conveyors spaced apart. Press the conveyor operation button to move one conveyor forward or backward to correct the direction of the wood so that it is almost parallel to the main rope of the lumber cableway, hang the wood over the bronze of the carrier, and then move the conveyor forward to move the wood forward or backward. In particular, whole trunk timbers, which are extremely difficult to handle due to their length and weight, can be automatically loaded onto a carrier, making it possible to safely load wood into the timber cableway's carrier with light work. At the same time, it is possible to reduce the occurrence of scratches on the wood.

Furthermore, this invention stores an appropriate number of lumber on two conveyors, so that it is not affected by the efficiency of the lumber collection work, and the lumber can be piled up by the conveyor at a constant interval with a high conversion rate. It is possible to carry out the work without coordinating with the timber collection work.
