DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insizing push-in blade for forming (sizing) a large number of small grooves on the surface of wood before preserving the wood.
The present invention relates to wood that has been processed by the insizing push blade to form a large number of small grooves.

[0002]

2. Description of the Related Art Preservative and termite processing has been conventionally performed in order to prevent biological damage to wood caused by termites, bark beetles and the like. As an example of the antiseptic termite processing, there is a method in which small grooves are cut in advance at an appropriate interval on a surface of wood by, for example, a notch forming blade (push-in blade for insizing), and a chemical is permeated into the wood from the small grooves. The process of cutting small grooves in the surface of wood is called insizing. For example, JP-A-56-6910
No. 3 discloses an insizing processing apparatus for performing insizing processing on wood.
In the insizing apparatus, the surface of the wood is cut by the cut forming blade while rotating the insizing blade having a large number of cut forming blades formed at predetermined intervals in the circumferential direction. Many small grooves are formed.

[0003]

When a large number of small grooves are formed on the surface of wood, it is necessary to effectively and deeply penetrate the chemical from the small grooves into the interior of the wood. , Number of small grooves (number per predetermined area)
Are important technical matters. There is a desire to more effectively penetrate the drug into the grooves formed by the determination of the scope of such technical matters.

An object of the present invention is to provide an insizing push-in blade for forming a small groove on the surface of wood to more effectively penetrate a chemical into the inside of the wood than the small groove formed by the determination of the above technical matters. It is an object of the present invention to provide wood having a small groove formed by a pushing blade for sizing.

[0005]

Means for Solving the Problems To solve the above problems, the invention according to claim 1 is, for example, pushed into the surface 90 of the wood 9 as shown in FIGS. In the pushing blade 7 for insizing forming the small groove 91, a pushing portion (for example, a bottom portion 8) for pushing the surface 90 of the wood 9 is provided, and the pushing portion 8 has a convex portion projecting in a direction orthogonal to the pushing direction. 82a or a depressed concave portion 82b is formed.

According to the first aspect of the present invention, the wood 9
The protrusions 82a protruding in the direction perpendicular to the pressing direction or the recesses 82b
When the pushing portion 8 is pushed into the surface 90 of the wood 9, the pushing portion 8 a or the recess 82 b is formed.
The side wall surface 91a of the side wall of the small groove 91 formed by being pressed is uneven. That is, when the pushing portion 8 is pushed into the surface 90 of the wood 9, the portion where the convex portion 82 a or the concave portion 82 b formed on the pushing portion 8 comes into contact is pushed off, and the side wall surface 91 a of the small groove 91 is brought into contact with the convex portion. It is formed in an uneven shape corresponding to the concave portion 82a or the concave portion 82b. Therefore, a small groove 91 having an uneven wall surface 91a can be formed on the surface 90 of the wood 9.

[0007] The side wall surface 91a of the small groove 91 is formed by pressing the pressing portion 8 so that the surface 90 is pressed off by the convex portion 82a or the concave portion 82b. At the same time, since the side wall surface 91a of the formed small groove 91 is uneven, the surface area is larger than when the side wall surface 91a is flat. Therefore, when the chemical liquid is permeated into the wood from the small groove 91,
The side wall surface of the small groove has a larger surface area than the flat side wall surface, the surface is rough, and the gap between the convex portions 82a or the concave portions 8 is formed.
Since the chemical solution penetrating by 2b can be held, the chemical solution can easily penetrate into the wood, and the chemical solution can more effectively penetrate into the wood.

[0008] When the pushing portion presses the surface of the wood, the surface that comes into contact with the surface of the wood may have a shape protruding at an acute angle toward the contact direction. With this configuration, the small groove formed by the insizing pushing blade has a side wall surface having an uneven surface in which the chemical solution easily penetrates as described above, and the small groove has a greater depth. Thus, it is possible to improve the permeability of the chemical solution penetrating from the small groove.

According to a second aspect of the present invention, in the pushing blade for insizing according to the first aspect, for example, as shown in FIGS. 5 to 8, the pushing portion 8 has a predetermined width (L).
1) It is formed in a substantially rectangular cross section having a dimension and a thickness dimension (L3), and extends along the width direction of the pushing portion 8.
An uneven portion 82 having a convex portion 82a projecting in the thickness direction and a concave portion 82b depressed is formed on at least one of the two side portions.

Here, the predetermined thickness dimension indicates, for example, the dimension of the short side of the pushing portion having a rectangular cross section, and the width dimension is
It shows the dimension of the long side of the pushing portion having a rectangular cross section. And
With these dimensions, a gap of a predetermined dimension is formed between the side walls of the small groove, and the dimension is such that the cut end is not closed even if the opposing side walls of the small groove are inclined in a direction approaching each other.
In other words, when the pushing part is pushed into the surface of the wood, the pressure is concentrated on the pushing part having a rectangular cross section, and a pressure sufficient to hold the wood in a compressed state can be easily applied to the wood. .

According to the second aspect of the present invention, the pressing portion 8 having a predetermined width and thickness and having a substantially rectangular cross section is provided with two side portions along the width direction of the pressing portion 8. Since the uneven portion 82 is formed on at least one of the side portions, the pushing portion 8 is formed on the surface 9 of the wood 9.
0, the small grooves 9 formed on the surface 90 of the wood 9 by the uneven portions 82 formed on the one side.
One of the side wall surfaces 91a can be formed in an uneven shape.

Also, the side wall surface 9 formed on the surface 90 is formed.
Since 1a is uneven, the surface area is larger than that of the flat side wall surface. Further, since the uneven side wall surface 91a is formed by being pushed by the uneven portion 82 of the pushing portion 8 pushed into the surface 90 of the wood 9, the surface becomes rough. Therefore, since the side wall surface 91a of the formed small groove 91 becomes a rough uneven surface, when the chemical solution is penetrated into the wood from the small groove 91, the side wall surface has a larger area than the flat side surface, and furthermore, the surface (Side wall surface) 91a is roughened so that the chemical liquid easily penetrates, and the liquid that penetrates between the projections 82a, that is, the concave parts 82b can be held, so that the chemical liquid can easily penetrate into the wood. The chemical solution can be effectively penetrated into the wood. In addition, uneven portions protruding in the width direction may be formed on both sides of the pushing portion 8. In this case, in the formed small groove, each of the opposing side walls has a rough uneven surface, so that the chemical solution can be more effectively permeated.

[0013] When the pushing portion presses the surface of the wood, the surface that comes into contact with the surface of the wood may have a shape protruding at an acute angle toward the contact direction. According to this structure, the small groove formed by the insizing pushing blade can have a deeper groove in addition to the side wall surface having an uneven surface where the chemical solution easily penetrates. It is possible to improve the permeability of a chemical solution that penetrates from above.

[0014] In addition, irregularities may be formed at both end portions of the pushing portion. In this case, the permeation of the chemical solution is effectively performed on both side surfaces of the formed small groove, and the above-described effect can be obtained.

According to a third aspect of the present invention, in the insizing push blade according to the second aspect, as shown in FIG. 9, for example, the width of the convex portion 84a of the concave and convex portion 84 and the concave portion 84b are provided.

Uneven portions 86 and 87 in each of the portions
Are formed, and the uneven portions 86 and 87 respectively formed on the two side portions are asymmetric with respect to a line S2 passing through the center between the side portions.

According to the fifth aspect of the present invention, it is possible to form the small groove 91B (see FIG. 12) in which the opposite side wall surfaces 912 and 913 are uneven surfaces and the side wall surfaces are asymmetric.

Irregular portions 84 and 85 are formed on each of the portions, and the concave and convex portions 84 and 85 respectively formed on the two side portions are symmetric with respect to a line S1 passing through the center between the side portions. And

According to the sixth aspect of the present invention, the opposing side wall surfaces 911 and 911 are uneven surfaces, and the both side wall surfaces 911 and 911 can form the symmetric small groove 91A. Therefore, the first to fifth aspects of the invention can provide the same effects as the first aspect of the invention.

The small groove formed on the surface 90 of the wood 9 by being pushed by the pushing blade 7 for insizing is shown in FIG.
Shown in FIG. 8 is an enlarged perspective view of a plurality of small grooves formed on the surface of the wood shown in FIG. The small groove 91 is formed by pushing the bottom surface 8 of the insizing pushing blade 7 into the surface 90, and the opposite side wall surface 9 of the bottom surface 8 is formed.
1a and 91a are formed on the wavy uneven surface by the uneven portions 82 and 83 of the bottom surface portion 8. The side wall surfaces 91a and 91
The dimension between the small grooves 91 is determined by a predetermined thickness dimension L3 of the pushing portion 8 (see FIGS. 6 and 7), and even if the side wall surfaces 91a of the small groove 91 are inclined in a direction approaching each other, the opening of the small groove 91 is opened. (Push-in port) has such a size that it is not blocked.

) Is driven to rotate around an axis by a drive mechanism (not shown), and the rotary blades 4, 4 are arranged so that their rotation axes R, R are parallel to and separated from each other in the left and right directions. When the wood 9 to be subjected to insizing is square in cross section, the rotary blade 4 is constituted by the same number of the insizing blades 5 as the rotary blade 3. Depending on the size and shape, the number of the insizing blades 5 constituting the rotary blade 3 and the rotary blade 4 is appropriately adjusted. In addition, the rotating blades 4, 4 can adjust the distance between them. In order to adjust the separation distance between the rotary blades 4, 4, for example, one of the pair of rotary blades 4, 4 is attached to a fixed table and the other is mounted to a movable table, and the movable table is driven by an appropriate driving means. This can be performed by moving the rotary blades 4 in the left-right direction, so that the separation distance between the rotary blades 4 can be adjusted according to the thickness of the wood 9 to be insized.

In order to form the small grooves 91 on the side surface (surface) 90a of the wood 9 by the rotary blade 4, the rotary blades 4, 4 are rotated while the rotary blades 4, 4 are rotated in the same manner as the above-mentioned rotary blades 3, 3. The blade 7 is attached to the surface (side surface) of the wood 9
90a. In detail, the rotary blade 4 having the insizing blade 5 is the same as the rotary blade 3 described above.
