Abstract

PURPOSE:To cut both the edges of a plurality of superposed veneers on a surface plate to a certain dimension by pressing the upper part of the veneer by a pressing piece on the side free from the contact with a cutter, when the edge part of the veneer is cut by the cutter, and by upwardly separating the pressing plate on the contact side with the cutter from the veneers on the start of cutting. CONSTITUTION:Single side of a plurality of superposed veneers 2 on a surface plate 1 are cut by a cutter 4. After the cutter 4 is lifted up, the veneer 2 is placed onto the surface plate 1, and after the other edge of the veneer 2 is shifted leftward up to the position of the cutter 4, the upper part of the veneer 2 is pressed by two pressing pieces 5 and 6. Then, the other edge of the veneer 2 is cut by the cutter 4, and the pressing piece 6 on the contact side with the cutter 4 is pressing-released upwardly to release the veneers 2 which are separat ed upwardly and in superposed state, and the upper part of the veneers 2 is pressed by the pressing plate 5 on the side free from the contact with the cutter 4. Therefore, the readward (rightward) release of the cutter 4 is prevented, and the veneer 2 can be cut to a certain dimension.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for cutting both ends of a veneer to be attached to the surface of a board, such as a laminated board, and more specifically, a method for cutting both ends of a large number of stacked veneers to obtain exact size ends. Concerning a method of obtaining a wood veneer.

[Conventional technology]

Conventionally, in order to obtain a veneer with exact size at both ends by cutting both ends of a large number of stacked veneers, as shown in FIGS. After pressing the upper part of the presser with the presser piece 3 and cutting one side with the blade 4, lift the blade 4 upward,
A veneer made by stacking a large number of veneers 2 is horizontally rotated 180 degrees with each constant plate 1, and the other end is cut in the same manner as described above.

[Problem to be solved by the invention]

In the conventional cutting method described above, after cutting one side of a large number of stacked veneers, in order to cut the other end, it is necessary to rotate the stacked veneer 180 degrees with the fixed plate. This may cause problems such as dimensional accuracy being compromised due to misalignment, and both ends not being parallel.

An object of the present invention is to solve the above-mentioned problems and to easily and easily cut both ends of a large number of stacked veneers to obtain a veneer with exact size at both ends.

[Means to solve the problem]

According to the present invention, one side of a large number of veneers stacked on a fixed plate is held down with a holding piece on top and cut with a blade, as in the conventional method, and then the blade is lifted upward to set the veneer in a fixed position. Move it horizontally until the other end comes to the position of the blade while placing it on the board, hold the top with two presser pieces, and as the blade cuts the end, continue to hold the top with the presser piece that is not in contact with the blade. When the presser plate in contact with the blade comes into contact with the blade or the veneer and starts cutting, the pressure is released and the cutting is performed by moving away from the veneer above the plate.

The present invention will be explained in detail below.

In the present invention, first, one side of a large number of veneered plates stacked on a fixed plate is cut with a blade while holding the upper part with a presser piece as in the conventional method.

Next, lift the blade upwards and move the veneer horizontally while keeping it on the fixed plate until the other end is at the position of the blade.

Although any means can be used to horizontally move, it is preferable to use a cylinder type, such as an air cylinder or a hydraulic cylinder, or a screw type.

The upper part of the veneer that has been moved in this way is held down by the presser piece that contacts the blade and the presser piece that does not contact the blade. When cutting the end of the veneer with the blade, the presser piece that does not touch the blade continues to press the top, and when the blade comes into contact with the veneer and starts cutting, the presser piece that is in contact with the blade uses appropriate means to cut the edge of the veneer. The pressure is released and the cut is made so that it moves away from the veneer in one direction. In this case, if you cut the other end of the veneer that has been moved as described above while holding down the top of the veneer, the shape of the blade (slope) at the end will be in the opposite direction from when cutting one side first.
This is because the blade escapes backwards during cutting, making it impossible to cut to exact size. Therefore, as mentioned above, if the presser piece that does not touch the blade continues to press the upper part, and the presser piece that contacts the blade releases the pressure from the start of cutting and moves away upwards, the veneer will escape upwards during cutting, and the blade will move backwards. It can be cut to exact size since there is no leakage. In addition, the release of the presser piece on the side where the blade touches is as follows.
The pressure may be increased rapidly, but the pressure may be gradually released as it descends to the blade.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 of the drawings is a sectional view showing the state in which one side is first cut, Figure 2 is a sectional view showing the state in which the veneer is placed on the fixed plate and moved horizontally until the other end comes to the position of the blade. FIG. 5 is a sectional view showing a state in which the presser piece in contact with the blade is released and cut.

As shown in FIG. 1, first, one side of a veneer made by stacking a number of veneers 2 on top of a fixed plate 1 is cut with a blade 4 while holding the upper part with a presser piece 3 in the same manner as in the conventional method. In the figure, 5 is a presser plate that does not touch the blade, and 6 is a presser plate that contacts the blade. Next, lift the blade 4 upward, and as shown in Figure 2, move the veneer horizontally (towards the left in the drawing) with the veneer placed on the fixed plate 1 until the other end is at the position of the blade 4, and press the upper part. Press with pieces 5 and 6. To move the veneer, for example, use the cylinder 7 as shown in FIG.
This can be done by moving the stopper 8, or by rotating the handle 9 as shown in FIG. This can be done by doing.

Then, as shown in Fig. 5, when cutting begins, the pressure on the presser piece 6 is released and the stacked veneers are released upward, causing the blade 4 to escape backwards (to the right in the drawing). Since there are no holes, it can be cut to exact size.

〔Effect of the invention〕

According to the present invention, both ends of a large number of veneers stacked on a fixed plate,
As in the conventional method, a large number of veneers are stacked on top of a fixed plate.
It does not require an 80° rotating device and can be easily cut to exact size.

Claims (1)

[Claims] One side of a large number of veneers stacked on a fixed plate is cut with a blade while the upper part is held down with a holding piece in the same manner as in the conventional method.Then, the blade is lifted upwards and the other end is cut with the blade while the veneer is placed on the fixed plate. Move horizontally until it reaches the desired position, hold the top with two holding pieces, and use the blade to cut the end.The holding piece that is not in contact with the blade continues to hold the top, and the holding plate that is in contact with the blade is pressed down with the blade. A method for cutting both ends of a veneer, characterized in that when the veneer comes into contact with the veneer and starts cutting, the pressure is released and the veneer is cut so as to move away from the veneer upward.
