On both sides of the rotary cutting blade 18 of the rotary shaft 17, roller bodies 19 as holding tools are rotatably attached to the rotary shaft 17, and these roller bodies 19 move the panel member as a workpiece on the surface plate 1 4 is pressed against the surface plate 1 side. In addition, the cutting rotary blade 1
8 and the roller body 19 follow the movement of the cutting rotary blade 8 from behind along the machining groove 13 while maintaining a constant height from the surface plate 1 and being supported by a rail or the like (not shown). Configured to be moved.

Next, regarding the operation of this embodiment, FIGS.
This will be explained with reference to the figures.

The panel member 4 as a workpiece placed on the surface plate 1 in a predetermined direction is cut by a cutting rotary blade 8 along the machining groove 13 as shown by the inclined two-dot chain line A in FIG. When the cutting rotary blade 18 and the roller body 19 as a presser are integrally moved at the same time,
The core material 3 is sequentially cut with a predetermined width by the rotary cutting blade 8 up to a predetermined height from the surface plate 1, and a tenon 31 (see FIG. 5) is formed. At the same time, the core material 3 and the face material 2 at the location above the predetermined height are
are sequentially cut by the cutting rotary blade 18.

At this time, both sides of the cut portion of the panel member 4 cut by the rotary cutting blade 18 are pressed against the surface plate 1 side by the roller bodies 19 on both sides of the rotary cutting blade 18, so that the cutting During processing, the panel member 4 does not spring up or flutter, and cutting and machining can be performed appropriately.

In this way, after the cutting of the face material 2, the cutting of the core material 3, and the formation of the tenon 31 in the portion that will become the end after cutting are performed at the same time, as shown in FIG. A panel having a predetermined shape is manufactured by attaching a core material 33 for the butt end, in which a notch 32 is formed to join the tenon 31, along the cut edge of the face material 2.

According to this embodiment, the following effects can be obtained.

That is, the cutting of the face material 2, the cutting of the core material 3, and the formation of the tenon 31 in the portion that will become the end after cutting are all performed in one work step, so that work efficiency is dramatically improved.

Moreover, even if the panel member 4 is cut from any direction of inclination, the tenons 31 are formed along the inclination direction at the end of the core material 3 at the cut edge, so that the tenons 31 are formed in a lattice shape with predetermined intervals. A panel member 4 of a predetermined size consisting of a face material 2 provided with a core material 3
By preparing a panel member 4 and appropriately cutting the panel member 4 into a predetermined shape, panels of various shapes can be easily manufactured.

Moreover, the rotating shafts 17 on both sides of the cutting rotary blade 18
is provided with a roller body 19 as a presser,
Since the panel member 4 as a workpiece is cut and cut while being pressed against the surface plate 1 side by this roller body 19, the cutting and cutting of the panel member 4 is always performed properly, and the cut surface and the cut surface are cut and cut. This has the effect of producing a clean finish, and the final manufactured panel also having a clean finish. This is particularly effective when cutting and cutting are performed in a direction oblique to the core material 3.

Further, since the cutting rotary blade 8 and the cutting rotary blade 18 are configured to be moved integrally with each other along a rail or the like (not shown), the operation is extremely simple, and it is easy to use an automatic feeding mechanism. be.

In the above-described embodiment, the cutting rotary blade 18 is provided at a location corresponding to the central position along the longitudinal direction of the rotary shaft 7 of the thick-blade-shaped cutting rotary blade 8. Depending on the shape of the tenon formed on each cut piece, the tenon does not necessarily have to be provided at a location corresponding to the central position, for example, when a chisel tenon is to be formed on one cut piece. In this case, it may be provided at a location corresponding to one end edge of the rotary cutting blade 8.

Furthermore, although the cutting rotary blade 8 has been described as having a single thick blade shape with a blade surface parallel to the rotation axis 7,
In cases where the tenon is to be formed at the same time as the place to attach the built-in ridge beam, or depending on the shape of the tenon, the tenon is not limited to a single thick blade shape, but may have multiple thick blade shapes with different diameters. You can. Further, the cutting rotary blade 8 may be formed with the center of the periphery protruding, for example like an abacus bead shape, and the blade surface of the cutting rotary blade 8 may be inclined with respect to the rotation axis 7. In such a case, a roof panel or the like that does not require a slope purlin or the like can be manufactured from the panel member 4.

Further, the cutting rotary blade 8 includes a plurality of flat blade pieces 12.
However, the present invention is not limited to this type of structure. For example, a structure having a substantially file-like cutting surface or a wave-like cutting surface around a short cylindrical body may be used. However, according to the flat blade piece 12 described above, there is an effect that the tenon 31 is formed neatly.

In addition, although the presser was assumed to be the roller body 19,
The present invention is not limited to this, and the tip of the presser in the moving direction may have an upwardly protruding shape, for example, a ski-like plate-like object, a rod-like object, or the like. Further, although the rotary cutting blade 8 and the rotary cutting blade 18 are each guided by a guide rail, etc., both the rotary blades 8 and 18 are placed on the side of the panel member 4 or along the cutting line by the rotary cutting blade 18. They may be connected together by a frame via a frame, and this frame may be guided by a guide rail or the like.
