Abstract

The method of oblong processing of wooden materials is based on the fact that the required number of incisions of required depth is made along the full length of the wooden material, oblongly toward the wooden material at once, and simultaneously this incised layer is cut in the horizontal direction. The equipment consists of four supports placed in a steel frame wherein on the first pair of supports the horizontal saw discs (3) are placed and connected with the driver (1) through the matrix (2). On the second pair of supports the vertical saw discs (5) with determining ringlets (6) are placed and connected with the driver (4). The saw discs (3, 5) are both vertically and horizontally adjustable toward each other and, at the same time, the whole system of saw discs (3, 5) is simultaneously vertically adjustable.

Description

Process and equipment for longitudinal processing of wood

The present invention relates to a process for the longitudinal processing of wood which is independent of the diameter and length of the material. The invention also relates to apparatus for carrying out the process.

Two circular saws are known for longitudinally cutting wood logs. The saws are arranged one above the other in the same cutting plane. This allows me to cut large diameter logs, but only in one plane. Apparatus for longitudinal cutting of semi-logs in a plurality of planes using a saw blade system is also known. However, this device does not allow for adjusting the cutting thickness and for example producing adjustable size prisms. There are also known devices for cutting wood with horizontal and vertical blades, which allows sawing in both planes. However, this machine does not allow for the greatest amount of versatility and can only handle limited thicknesses up to 20 cm.

The above drawbacks are overcome by the method of longitudinal cutting of the wood according to the present invention and the apparatus implementing it. This is based on the principle of making the desired number and depth of cuts along the entire length of the wood toward the wood from the top, in the longitudinal direction, while simultaneously cutting the cut layer horizontally. After cutting the set thickness · · · · in one plane, another layer is set and the operation is repeated.

The device carrying out the process according to the invention has supports mounted on a steel frame that move in a vertical direction. The actuator has four brackets arranged as follows: The axis of the vertical saw blades is located on two brackets on the right side of the actuator and the holder of the horizontal blade shaft is on the left. The horizontal discs are riveted to special hubs which are fixed to the drive shaft.

The proposed technique provides high precision cutting, ideal product processing with high productivity.

The horizontal blade mounting method is very advantageous and allows quick disassembly.

In the drawing it is

Figure 1 is a sketch of the position of the saw blades relative to the wood during the incisions to be made in the wood;

Figure 2 is a side view of the horizontal saw blade mounting to the special hub and drive shaft.

The apparatus according to the invention has a circular saw located on four supports in a steel frame. As shown in Fig. 1, the first pair of supports are provided with horizontal saw blades 3, which are connected via special hubs 2 through axles 8 to a drive mechanism 1. The second pair of supports are provided with vertical saw blades 5 which are connected to the drive mechanism 4. The vertical saw blades 5 are positioned across the desired widths via positioning rings 6. The horizontal saw blades 3 are inserted into the hub 2 through their central slit and secured by riveting 9 around their circumference.

Fig. 2 shows the attachment of the horizontal saw blade 3 to a hub 2 with rivets 9. The hub 2 is connected to the drive 1 via the shaft 8.

When operating the apparatus in accordance with the process of the invention, it will be apparent from Figure 1 where the wood is processed and where the cuts are made.

The first cut into the wood 7 is made at the same time as the horizontal saw blades 3. Thereby the upper layer of the wood is cut along its entire length. The mass thus prepared is cut at the desired location with the horizontal saw blades 3 and simultaneously with the vertical saw blades 5. In the case of large-size timber, where the horizontal blades 3 cannot cut through the entire layer at the same time, the horizontal blades 3 and the vertical blades 5 are simultaneously used to cut the wood 7 from both sides, which allows the transverse movement of the supports. After a layer has been cut from the mass, the supports are moved downward as desired and the entire operation is repeated.

By attaching the special horizontal saw blades 3 to the special hub 2 with rivets 9, these saw blades can be adjusted to the full width of the timber 7 to be cut, thus allowing the cutting of high-thickness timber 7 with small diameter blades.

The holders of the horizontal saw blades 3 may be adjusted in the height direction towards the vertical saw blades 5 when vertical blades 5 of different diameters are to be used, resulting in a cutting plane in both the vertical and horizontal positions. The rotation of the horizontal saw blades 3 is selected by cutting the inner side of the wood 7. thus extending its life. For the reasons stated above, one of the two threads of the hub is right-handed and the other is left-handed to prevent twisting. The horizontal saw blade 3 is inserted through its central slot into the hub 2 and secured by riveting 9 around its circumference.
