[0002]

2. Description of the Related Art Conventionally, in a prefabricated building by a wood panel construction method, a flat rectangular wood panel 1 shown in FIG. 14 is frequently used. The wood panel 1 is formed by attaching face materials 3 to both front and back surfaces (or one surface) of a plurality of framed core materials 2. A plurality of grooves 5 extending in the thickness direction are provided on each of the four end surfaces 4 of the wood panel 1, and when the plurality of wood panels 1 are juxtaposed by abutting the end surfaces 4, the grooves are mutually formed. 5, the bolt hole is formed.

[0003]

However, the processing for providing the grooves has been performed manually in a wood panel manufacturing line. For this reason, the processing time was not stable, and it was difficult to efficiently process the wood panel sent at regular intervals. In addition, the heavy tools used have also been a factor in reducing work efficiency.

[0004] It is an object of the present invention to provide a wood panel grooving apparatus, a grooving line, and a cutting blade capable of improving the processing efficiency.

[0005]

SUMMARY OF THE INVENTION The present invention aims at achieving the above-mentioned object by mechanizing a manual groove processing. Specifically, the wood panel groove processing apparatus of the present invention will be described using reference numerals in the embodiment.
A wood panel grooving device 20 (or grooving device 120) for performing grooving in the thickness direction on an end surface 4 of a flat quadrangular architectural wood panel 1, which is a substantially rectangular parallelepiped in which the wood panel 1 is placed flat. Positioning means provided on the main body portion 21 and two end surfaces 4A and 4B of the wood panel 1 provided on the two side surfaces 21A and 21B at right angles to each other and corresponding to the side surfaces 21A and 21B. 25,2
6 and 27, and a cutting blade 50 having a predetermined blade width dimension and provided on at least one side surface 21A of at least one of the two side surfaces 21A and 21B provided with these positioning means 25, 26 and 27. The cutting tool 50 is configured to include the cutting means 22.
Contact with the end face 4A of the wooden panel 1 by
The other of the two side surfaces 21A and 21B of the main body 21
There is another positioning on the side 21D side facing the side 21B.
Means 59 for positioning the one side 21A.
25 and positioning means 27 on the other side surface 21B.
Positioning means 26 on the side 21A and another positioning
The means 59 includes the wood panel 1 along the feeding direction.
By moving, these side surfaces 21A, 21B,
End faces 4A, 4B, 4D of wooden panel 1 corresponding to 21D

You. For this reason, compared to performing grooving manually,
Business efficiency is significantly improved. Furthermore, for example, in the case where a plurality of grooves 5A to 5D are provided on the end face 4A of the wood panel 1, these grooves 5A to 5D have a dimension from one end of the end face 4A in the longitudinal direction (direction orthogonal to the thickness direction). The grooves 5A and 5B are defined, and the grooves 5C and 5D whose dimensions from the other end are defined. In addition, the wood panel 1 is different in terms of the length itself in the longitudinal direction. For example, when a plurality of types are prepared, simply positioning with one positioning means 25 and the other positioning means 27 will result in any size of the wood panel for the grooves 5A and 5B whose dimensions from one end are defined. In the case of No. 1, processing can be performed at the same position irrespective of the difference in the dimension in the longitudinal direction. However, for the grooves 5C and 5D whose dimensions from the other end are defined, from the one end of the grooves 5C and 5D. The dimensions of the tree Panel 1
In order to machine the grooves 5C and 5D, each time the size of the wooden panel 1 changes, the cutting means 2
I have to change the position of 3. However, as described above, when another positioning means 59 is provided on the side surface 21D facing the other side surface 21B, the grooves 5C and 5D whose dimensions from the other end are defined allow the wood panel 1 to be connected to the one side surface 21A.
By using the positioning means 26 and another positioning means 59, the wood panel 1 can be processed at the same position regardless of the difference in the dimension in the longitudinal direction.
For this reason, the groove processing of the wooden panels 1 having different longitudinal dimensions can be easily performed.

[0007] Further, in the groove processing apparatus for wood panel of the present invention, the cutting means 22 may be provided on the side surface 21A of the main body 21 so as to be horizontally movable. When the grooves 5A and 5B are provided,
These grooves 5A and 5B can be easily machined by moving one cutting means 22 horizontally.
There is no need to provide a cutting means for each B.

Further, in the wood panel grooving apparatus of the present invention, the cutting means 24 may be provided on the other side face 21B of the main body 21, and in such a case, the two end faces 4A, 4B groove processing can be performed, and work efficiency is further improved.

In the wood panel groove processing apparatus of the present invention, the positioning means 25-27 may be provided integrally with the cutting means 22-24.
Positioning means 25 to 27 near the side surfaces 21A and 21B of the
Need not be provided separately, which simplifies the structure of the device and reduces the manufacturing cost of the device.

Furthermore, in the wood panel grooving apparatus of the present invention, the cutting blade 50 is rotated about a horizontal axis 49 parallel to the end face 4 of the wood panel 1, and the two cutting blades are arranged at an interval.

It is preferable that the circular pitch P1 between the adjacent blades of the rotary intermediate blade 54 is larger than the circular pitch P2 of the rotary end blade 53. In such a case,
By making the circular pitch P1 of the rotary intermediate blade 54 larger than the circular pitch P2 of the rotary end blade 53, the rotary end blade 53 first comes into contact with the end face 4 of the wooden panel 1 so that two narrow strips are formed. The groove 5A is formed, and subsequently, the rotary intermediate blade 54 comes into contact to cut the gap between the grooves 5A, thereby forming the groove 5 having a predetermined width. At this time, since the rotating end blade 53 is thin, the cutting resistance is small,
The finished state of the cut surface by the rotary end blade 53 is good. Further, in the rotary intermediate blade 54, since the portion sandwiched between the grooves 5A is cut, the cutting resistance is reduced, and the finished state of this portion is also improved. Therefore, the finished state of the entire groove 5 becomes good. In addition, since the rotating end blade 53 and the rotating intermediate blade 54 have the same diameter, the two grooves 5 on the rotating end blade 53 that first contact.
A does not become a deep groove as compared with the portion cut by the rotating intermediate blade 54. As described above, the finishing work such as manual work of the groove 5A becomes unnecessary, and the working efficiency is further improved.

In the groove processing apparatus for woody panels according to the present invention, the rotary intermediate blade 54 may be a twisted blade. In such a case, the cutting resistance is further reduced, and a better finished state is obtained.

Further, in the wood panel grooving apparatus of the present invention, the wood panel 1 may be mounted on the uppermost portion of the main body 21 and the cutting means 22 to 24 may be provided below the wood panel 1. For example, cutting means 22 to

As shown in FIG. 1, the second grooving device 120 is basically the same as the first grooving device 20 described above. Therefore, here, the second grooving device 120 will be described in detail. Are omitted, and only the differences will be described. That is,
The second grooving device 120 is installed so that the positions of the cutting devices 22 to 24 are point-symmetric with respect to the direction of the first grooving device 20. In the grooving device 120, the cutting devices 22 and 24 are used. Groove 5 whose dimensions from corner 8 are defined by
G, 5H, 5K, and 5L are processed, and the grooves 5I and 5J whose dimensions are defined from the corner 9 are processed by the cutting device 23. 3).

Next, a processing procedure in the first processing apparatus 20 will be described with reference to FIGS. In FIG. 8, first,
The cutting devices 22 to 24 and the holding device 35 are all lowered, and the turning member 55 is made to appear, and the wooden panel 1 carried in from the upstream is brought into contact with the turning member 55 and stopped (A). . Next, by raising the cutting devices 22 and 24 to an intermediate position in the vertical direction, the contact portions 25 (see FIG. 3) and 27 appear at a position higher than the roller conveyor 28, and the roller conveyor 28 is reversed. The wooden panel 1 by the contact portions 25 and 27
, Thereby positioning the wooden panel 1 (B). Thereafter, the upper surface of the wooden panel 1 is pressed by the pressing device 35, and the wooden panel 1 is
Is difficult to be generated. And cutting device 2
2, 24 are once lowered (C). Next, the cutting blade 5
0 is rotated, and the grooving is performed while raising the cutting devices 22 and 24. Further, after the cutting devices 22 and 24 descend, the cutting devices 22 and 24 are horizontally moved and the groove processing is repeated (D). As a result, the grooves 5A, 5B,
Processing of 5E and 5F is completed. Further, in FIG.
The cutting device 23 is raised halfway in the vertical direction to
6 and the rotating member 55 are made to appear, and the wooden panel 1 is brought into contact with them to perform positioning (E). Then, while holding the wood panel 1 with the holding means 35 and making the misalignment less likely to occur with the auxiliary device 32, the cutting device 24 is once lowered (F). Next, the cutting device 23 is raised to perform grooving, and when the cutting device 23 is lowered, its position is changed and grooving is repeated (G). Thus, the processing of the grooves 5C and 5D is completed.
Lastly, the wooden panel 1 is carried out to the second processing device 120 side by lowering the pressing device 35, housing the rotating member 55, and rotating the roller conveyor 28 forward.

According to this embodiment, the following effects can be obtained. That is, in the grooving line 10, the first and second grooving devices 20 and 120 are used to perform the grooving of the wooden panel 1. The two end faces 4A, 4B, 4C, 4D of the panel 1 which are at right angles to each other are
27 and the positioning means 59, it is only necessary to determine the position, and the groove processing can be performed automatically by raising and lowering the cutting devices 22 to 24. For this reason, the working efficiency of the groove processing can be significantly improved.

The first and second grooving devices 2 are used for grooving.
Since the processing is performed separately for 0 and 120, the processing time (tact time) required for one apparatus can be shortened. On this occasion,
In the first grooving device 20, the grooving of the end faces 4A and 4B can be performed by one-time positioning of the wood panel 1, and similarly, in the second grooving device 120, the end surfaces 4C and 4C can be formed by one-time positioning.
Since 4D groove processing can be performed, there is no need to perform positioning for each processing of the end faces 4A to 4D. Further, the first grooving device 20 and the second grooving device 120 include the cutting devices 22 to 2.
4 are installed so as to be point-symmetric with respect to each other.
Can be sent to the second grooving device 120 in the same direction, and the second grooving device 120 can automatically make the end faces 4C and 4D correspond to the cutting devices 22 to 24. Accordingly, it is possible to save the trouble of inverting the wooden panel by 180 degrees and sending it. Furthermore, since the width dimension of the cutting blade 50 is the same as the width dimension of the groove 5, the cutting device 22
It is possible to provide the groove 5 having a predetermined width dimension only by moving up and down once to 24. With these, the working efficiency can be further improved.

Further, the first and second groove processing devices 20 and 120
Then, when performing the groove processing of the end surfaces 4A and 4C of the wooden panel 1, the grooves 5A, 5B,
For 5G and 5H, the wood panel 1 is attached to the contact portions 25 and 2.
The wood panel 1 is brought into contact with the contact portion 26 and the positioning means 59 in the grooves 5C, 5D, 5I, and 5J in which the dimensions from the corners 7 and 9 are defined. Even if another panel having a different length in the feed direction is carried in as the wood panel 1, each corner 6 to 9 of the grooves 5A to 5D and 5G to 5J is used. Since the dimensions from are constant, the wood panels 1 having different lengths can be grooved by the first and second groove processing devices 20 and 120 irrespective of the difference in length. On the other hand, both the grooves 5E and 5F of the end face 4B perpendicular to the feed direction have dimensions defined from the corners 6, and the grooves 5K and 5K of the end face 4D
5L both have the dimensions from the corner 8 defined,
These dimensions are constant even if the width dimension (dimension in the direction perpendicular to the feeding direction) of the wood panel 1 is different, so that the wood panel 1 of different width is processed regardless of the difference in width. it can. That is, the first and second grooving devices 2
At 0, 120, a plurality of types of wood panels 1 having different outer diameters can be grooved. At this time, in particular, the groove 5
A, 5B, 5G, and 5H are processed by the cutting device 22 and the grooves 5 are formed.
Since C, 5D, 5I, and 5J are processed by the cutting device 23, it is possible to save the trouble of moving one cutting device by moving it horizontally largely.

Since the wood panel 1 is placed on the top of the main body 21 and the cutting devices 22 to 24 are provided below the wood panel 1, the cutting devices 22 to 24 are provided above the main body 21. Compared to the case of providing 24, it is not necessary to provide a tower-shaped frame or the like, and the structure of the device can be simplified, and since there is no such frame, the operation of the wood panel 1 by the operator can be easily performed. Can be. And cutting device 22 ~
24 are horizontally movable, so that the grooves 5 are formed in the end faces 4A to 4D.
When providing A to 5L, the cutting devices 22 to 24 may be horizontally moved to predetermined positions. Therefore, it is not necessary to provide the same number of cutting devices as the number of grooves 5A to 5F.
The manufacturing cost of the second groove processing devices 20 and 120 can be reduced. Further, since the contact portions 25 to 27 are provided integrally with the cutting devices 22 to 24, the side surfaces 21A and
It is not necessary to separately provide the contact portions 25 to 27 in the vicinity of 21B, so that the structure of the device can be further simplified, and the manufacturing cost can be further reduced.

In the cutting tool 50, the circular pitch P1 of the main cutter 54 is equal to the circular pitch P2 of the disk cutter 53.
Since two grooves 5A having a narrow width are formed on the end face 4 of the wood panel 1 by the disk cutter 53, the space between the grooves 5A is cut by the main cutter 54. Thus, a groove 5 having a predetermined width is formed. Therefore, since the disk cutter 53 has a thin width, the cutting resistance is small, and the finished state of the groove 5A can be improved. Further, since the main cutter 54 cuts the portion sandwiched between the grooves 5A, the cutting resistance is small, and the finished state of this portion can be improved. Therefore, the finished state of the entire groove 5 can be made good without fuzz. Further, since the main cutter 54 is a twisted blade, the cutting resistance is further reduced, and the finished state can be further improved. In addition, the disk cutter 53 and the main cutter 54
Since they have the same diameter, the two grooves 5A of the disk cutter 53 that come into contact first do not become deeper than the part cut by the main cutter 54. Thus, finishing work such as manual work can be omitted in the groove 5, and work efficiency can be improved from this point as well. Further, since the cutting blade 50 is divided into the disk cutter 53 and the main cutter 54, the cutting blade 50 can be disassembled into the respective cutters 53 and 54, and the cutting edges thereof can be accurately ground by the same degree. Cutters 53, 54
Can be reliably maintained at the same diameter, and there is no fear that the groove 5A becomes a deep groove, or conversely, the groove 5A becomes a shallow groove, and it is possible to reliably prevent fluffing during processing by the main cutter 54. In addition, by polishing the cutters 53 and 54, the cutters 53 and 54 can be repeatedly used, which is economical.

[Second Embodiment] FIG. 10 shows a cutting tool 50 according to a second embodiment of the present invention.
