  The present inventor has made various studies in order to solve the problems of the conventional technique. As a result, there is provided a method and an apparatus for easily obtaining a wood lump that is gentle on human skin, warm to the touch, rich in hygroscopicity, and extremely advantageous in adjusting humidity, and that can reduce the possibility of slipping as much as possible. It is in.

In order to solve the above technical problem, a spherical wood lump manufacturing method according to claim 1 of the present invention is a method in which a lump of wood is put into a sealable cutting box and then provided inside the cutting box. A large number of cutting tools are forcibly rotated with respect to the cutting box so that the wood lump is brought into contact with these cutting tools, and the wood lump is sequentially cut into a spherical shape while being cut by the cutting tool. Further, as a specific apparatus for carrying out this method, as described in claim 2, a large number of cutting tools are provided such that the inner peripheral wall of a cutting box that can be sealed with a lid at the inlet is rotatable. These cutting tools are configured to be forcibly rotated by a prime mover provided outside the cutting box.

  According to the configuration as described above, a large number of the end materials housed in the cutting box are forcibly rotated, contacted with the internal cutting tool several dozen times, and the corner portions are sequentially cut. Then, the surface gradually becomes a spherical surface, and finally it is changed to a spherical or oval wood mass.

Therefore, this invention has the following effects.
As described above, the spherical wood lump production method and apparatus according to claim 1 of the present invention is a cutting tool that is forcedly rotated for a predetermined time by simply putting a wood end material into a cutting box. By rotating this end material in contact with it, a spherical or egg-shaped lump of wood can be obtained, so the work for making a cube or rectangular parallelepiped end material into a spherical shape is very simple and efficient, for example, Compared to the case of cutting one by one, it has become possible to provide much cheaper. In addition, by enabling mass production, the range of application as a material can be applied to, for example, foot pedal mats for health, flooring materials for foot massages at bathing areas and various event plazas, as well as interior and exterior materials for buildings. Specifically, it can be applied to architectural panel materials such as walls, pillars, ceilings and floors, and paving materials such as paving stone substitutes and sidewalks and promenades.

In the above configuration, as described in claim 3 in the present invention, the cutting tool is a knife, comprising at least one of either or sandpaper and other two kinds of cutting tool rasp or sandpaper is combined Is desirable.
This is because an efficient cutting operation can be achieved.

Furthermore, as according to claim 4, desirably the cutting box Ru is forcibly rotated.
Needless to say, the cutting efficiency can be improved.

  It is easy to obtain a wood block that is gentle on human skin, warm to the touch, highly hygroscopic and very advantageous in adjusting humidity, and that can reduce the risk of slipping as much as possible. The purpose of providing a block body with a rough surface can be realized with a remarkably simple structure and low cost.

[Example 1]
First, a spherical wood lump manufacturing method and apparatus according to the present invention will be specifically described below with reference to FIG.

FIG. 1 is an overall explanatory view of a method and apparatus for producing a spherical wood lump.
As shown in FIG. 1, the end material 1 is used for a wood lump. The end material 1 is preferably a rectangular parallelepiped or a cubic shape as a rectangular parallelepiped. This is because the wood lump 2 after the cutting process has a beautiful spherical shape or oval shape. Of course, it goes without saying that it may be a distorted wood lump. The possibility of becoming an unpredictable shape is great, which increases the fun.

  The end material 1 is put into the cutting box 4 from the inlet 3. A lid 5 is provided at the insertion port 3, and the cutting box 4 is sealed by closing. When the end material 1 is completely charged, the closing port 3 is closed with the lid 5, and sandpaper as an example of a plurality of cutting tools 6 provided in the cutting box 4 is forcibly rotated. Is forcibly stirred in the cutting box 4 and brought into contact with a plurality of sandpapers. This sandpaper is configured to forcibly rotate by the action of a prime mover (electric motor) 7. By contact with the sandpaper, the corners of the end material 1 are sequentially cut and finally formed into a spherical or egg-shaped wood lump 2.

  If the cutting box 4 itself is forcibly rotated by the prime mover (electric motor) 8 in the above processing steps, the cutting efficiency can be further increased. Furthermore, it is desirable that the cutting box 4 and the cutting tool 6 repeat forward and reverse rotations every predetermined time. In addition to the sandpaper 6, a file or a cutter can be used. Inevitably, the cutting tool 6 such as sandpaper, file, and cutter can be freely changed, and the holding tool 9 that is fixedly held is fixedly or forcibly rotated in the cutting box 4. Needless to say, it is provided. In the figure, reference numeral 10 denotes a frame for supporting an electric motor 7 for rotating the cutting tool 6 on the outer wall of the cutting box 4.

  According to the spherical wood lump manufacturing method and apparatus according to the first embodiment described above, the wood end material 1 is simply put into the cutting box 4 and forcibly rotated for a predetermined time, thereby forming a spherical shape or an oval shape. Therefore, the work for converting the cube shape or rectangular parallelepiped shape into a spherical shape is very simple and efficient, and is far less expensive than, for example, cutting one by one. Now available. In addition, by enabling mass production, the range of application as a material can be applied to, for example, foot-mats for health, floor materials for foot massage in bathing areas and various event plazas, and the interior and exterior materials of buildings, Specifically, it can be extended to building panel materials such as wall surfaces, pillar surfaces, ceilings, floors, and paving members such as paving stone substitutes, sidewalks, and promenades, and has great industrial value.

[Example 2]
Next, the wood mass 2 obtained as described above is used for, for example, a foot-mat for health, a mat for foot massage in a bathing area or various event plazas, and also a wall, a column surface, a ceiling as an interior / exterior material of a building Examples of the present invention applied to so-called materials such as floors and pavement members will be described in detail below with reference to FIGS.

  FIG. 2 is an external view showing a material 12 in which a spherical wood lump 2 is arranged and fixed on a base 11, and FIG. 3 is a partially enlarged sectional view thereof. The material 12 has ten to several tens of wood blocks 2 fixed to the base 11 only in one layer. The material 12 shown in the figure represents a stepping health mat.

  There is no limitation on the material and shape of the base 11. The material can be anything such as rubber, plastic, metal, rock, concrete, etc. The shape can be anything such as film or molded product. Moreover, the use of the obtained raw material 12 does not ask | require. As described above, it can also be used as various items as well as interiors.

  Ideally, a resin 13A as an example of the fixing means 13 is applied to the surface of the base 11 on the side where the wood block 2 is arranged and fixed. The resin 13A may be anything, and any resin may be used as long as it has a function of fixing the base 11 and the wood lump 2. Examples of the resin 12A include various resins such as urethane, epoxy, ethylene vinyl acetate, vinyl chloride, acrylic, and polyester. As the fixing means 13, a material that can ideally fix both the base 11 and the wood lump 2 may be used. Besides resin, cement and various adhesives, and although not shown, nails, screws, etc. Can also be adopted. In using the adhesive, it may be used on the base 11 side, but the adhesive may be applied to the surface of the wood lump 2 and, if possible, the lower half portion to be embedded (see FIG. 3).

  In order to apply the liquid fixing means 13 such as resin or adhesive to the base 11, known means such as spraying or dipping can be employed. Further, when the base 11 is made of, for example, silicon resin, it may be embedded directly. In this case, the surface of the wood block 2 is embedded as necessary, as described above. You may make it apply | coat an adhesive agent to the lower half part.

  When the wood block 2 is arranged and fixed on the base 11, at least a portion exposed upward from the surface of the base 11 has a hemispherical shape, and the lower half is generally embedded in the base 11. desirable. Needless to say, this is to prevent the wood block 2 from being easily detached from the base 11. When the base 11 is made of wood, the wood block 2 is cut in half, the cut surface is directed to the surface of the base 11, and is placed and fixed using a fixing means 13 such as a nail, screw or adhesive. You can also.

  In the example shown in FIGS. 2 and 3, the thickness of the base 11 is about 15 mm, and the radius of the wood block is about 25 to 35 mm. However, the dimensions may be appropriately selected depending on the applied material, and are not limited to this example.

[Specific Example 1]
A specific example in the case where a healthy stepping mat 14 as one specific example of the material 12 is created using the wood block 2 obtained by the container embodiment 1 will be described below with reference to FIG.
This healthy stepping mat 14 employs silicon resin for the base 11. As shown in FIG. 4A, first, silicon resin, which is an example of the base 11, is poured into the pallets 15 each having a 30 cm square length and width. Next, as shown in FIG. 4 (B), while the molten silicon resin is not solidified, the wood block 2 is pushed into the silicon resin in an appropriate balance, until the wood block 2 is firmly fixed. Waited for solidification. The resulting healthy foot mat 14 (see FIGS. 2 and 3) has a good cushioning property of the base 11 made of silicon resin, a natural warm feeling of the wood lump 2 and a gentle touch, and a consumer who desires a natural orientation in recent years. It matches the demands of

[Specific Example 2]
Next, a specific example in the case where a paving stone substitute material 16 as one specific example of the material 12 is created using the wood block 2 obtained in Example 1 will be described below with reference to FIG.
In this paving stone substitute material 16, a rock 17 having a flat surface is used for the base 11. As shown in FIG. 5A, a resin material as an adhering means 13 for improving the adhesion between the flat surface of the rock 17 and the wood mass 2, for example, an epoxy resin is applied to the flat surface of the rock 17. . Next, as shown in FIG. 5 (B), the wooden blocks 2 were sequentially arranged, and the paving stone substitute 16 was obtained after the epoxy resin as the fixing means 13 was solidified. The obtained paving stone substitute 16 has a natural warm feeling and gentle touch of the wood lump 2, and is well matched to the demands of consumers who want a natural orientation in recent years. Also, there is little risk of slipping.

  In the above embodiment, in order to assist the adhesion with the wood lump 2 on the flat surface of the rock 17 as the base 11, first, a resin material, for example, a urethane resin coating film is formed, The above-mentioned adhesive, that is, means for applying an epoxy resin can also be employed.

  In the above specific examples, since the applied material 12 has a comparatively small size, it can be created manually, but mechanization is also necessary from the viewpoint of increasing productivity. In such a case, as shown in FIG. 6, for example, molten silicon resin serving as the base 11 is supplied at a predetermined thickness onto a belt conveyor 19 that is provided with dams 18 on the left and right and circulates, and this supply of silicon resin is performed. A chute 20 is provided at the lower side of the part with a width that is the full width of the conveyor, and a large number of the wood masses 2 are sequentially dropped onto the silicon resin that flows sequentially from here, so that the wood masses 2 are spread over the entire surface of the base 11. Just do it. Then, it cuts into a required dimension.

  Further, in each of the above specific examples, the wood lump 2 is arranged and fixed from above the fixing means 13, but in addition to such means, as shown in FIG. If the wood lump 2 is embedded in the fixing means 13 and solidified in substantially the same way as the diameter of the wood lump 2, then the timber lump 2 is exposed to the surface by, for example, blasting 21. Good. At this time, depending on the type of the fixing means 13, it is necessary to make sand blasting or shot blasting, and to adjust the size and impact speed of the particles appropriately.
