【Example】
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the first embodiment, the method of manufacturing a container or decoration using the bamboo 10 is as follows. For example, the raw bamboo 10 is cut between the nodes 28 and 28 as shown in FIG. Thus, the bamboo cylinder 12 is cut out to remove the outer skin 20 which is a blue-colored skin to expose the white body portion of the bamboo body, and the slope is formed on the outer surface of the body portion 14 of the bamboo cylinder 12 from which the outer skin 20 is removed. 16 includes a preliminary process for forming 16, a drying process for volatilizing residual moisture from the bamboo cylinder 12 subjected to the slope processing in the preliminary process, and a finishing process for finishing design shaping, polishing, painting, and the like on the dried bamboo cylinder 12. Yes. In addition, the cut-out portion of the bamboo tube may cut out the node portion across one node or two or more nodes.
[0013]
As shown in FIG. 1, the trunk wall of the raw bamboo 10 is composed of an inner bamboo body portion 18 and an outer skin 20 that covers and integrally covers the outer side. The bamboo body portion 18 includes a number of conduits 24 that run densely in the longitudinal direction of the bamboo. Most of the residual moisture in the raw bamboo 10 is contained in the conduit 24, and this residual moisture contains bamboo oil and aqua.
[0014]
In the preliminary process, for example, a portion between the nodes 28 and 28 of the long raw bamboo 10 is cut out. The cut-out portion is a bamboo cylinder 12 that is a hollow, substantially circular cylindrical shape having both ends 22 opened in the direction along the longitudinal direction of the cylinder center of the trunk portion 14.
[0015]
The bamboo cylinder 12 is cut out to remove the outer skin 20, which is a blue-colored skin, so that the base portion of the white bamboo body is exposed. Compared with the white pigment ground portion inside the bamboo body, the outer skin 20 portion having a blue color has a smaller diameter and a higher density of the fiber tube bundle. Therefore, if it is dried with the outer skin held, only the both ends, which are cut surfaces, are extremely contracted and deformed, and this portion needs to be cut to reduce the yield, and the drying effect It cannot be obtained sufficiently and causes dry cracks over time. A sufficient drying effect over the entire bamboo can be obtained by performing the drying process described below with the skin of the raw bamboo removed.
[0016]
In the present invention, after removing the outer skin, as shown in FIG. 2, the cutter is applied to the end portion side 22 of the bamboo cylinder 12, and is cut deeper as it approaches the end along the longitudinal direction of the cylinder core. A slope 16 is formed to descend toward the part side 22. As a result, the drying effect over the entire bamboo in the drying process is promoted and drought prevention is fully realized. 3 is a central longitudinal sectional view of the bamboo cylinder 12 having the slope 16 formed thereon, and FIG. 4 is an enlarged view of the slope 16 portion. Forming a slope 16 on both end sides 2 2 in this embodiment. The cylindrical flat part remaining without being inclined in the middle of the body part 14 scrapes off the outer skin 20 to expose the bamboo body part 18. That is, in the preliminary process of the present embodiment, the bamboo cylinder 12 is a barrel-shaped cylinder composed of only the bamboo body portion 18 whose outer surface is formed into a barrel-shaped surface, and a large number of cut openings 26 of the conduit 24 are exposed on the outer surface of the trunk section 14. ing.
[0017]
Specifically, as shown in FIG. 4, a large number of conduits 24 are cut obliquely by the inclined surface 16, and a large number of elongated elliptical cutting openings 26 are exposed on the inclined surface 16, as shown in FIG. Yes. The means for forming the inclined surface 16 is suitable because the cutting opening 26 is not easily crushed when it is cut with a cutting tool that can cut well. The slope 16 may be formed by polishing with a belt sanding machine or the like, but the belt speed and abrasive grain roughness are adjusted so that the cutting opening 26 is not crushed or filled with abrasive powder. Process. It should be noted, may be carried out oil drain by boiling prior to applying the slope processed into bamboo 1 2. By forming the elongated elliptical cut opening 26 in the conduit 24 by the slope 16 and then performing the drying step, the residual moisture in the conduit 24 can be efficiently volatilized and the bamboo cylinder 12 can be sufficiently dried.
[0018]
Next, a drying process is performed. In the drying process of the present embodiment, the bamboo cylinder 12 subjected to the slope processing in the preliminary process is dried for about 30 minutes using an industrial microwave dryer. The dryer may be a fuel burner dryer or other drying device.
[0019]
Next, a finishing process is performed. As shown in FIG. 5, in the finishing process of the present embodiment, the ak eluted to the slope 16 and remaining is scraped off by a belt sanding machine, and at the same time, the body portion 14 is finished into a product curved surface. Furthermore, design cuts and the like are added to add design, and after deburring polishing, washing, etc., lacquer is applied several times, and a bottom plate 32 is attached to finish the container. The paint may be urethane paint or unpainted. Moreover, you may finish by performing painting, inlaying, etc. suitably.
[0020]
Here, the operation of the present embodiment will be described. When the bamboo cylinder 12 is heated in the drying process, residual moisture is heated. Since most of the residual moisture is contained in the conduit 24, the heated residual moisture is volatilized actively as water vapor from the cutting opening 26 that is wide and elongated in the slanted surface 16 as shown in FIG. . Moreover, since the outer surface of the trunk | drum 14 has remove | excluded the outer skin | shell 20 completely, the water | moisture content which remained in parts other than the conduit | pipe 24 is volatilized easily. The fully dried bamboo cylinder 12 will hardly crack after being finished into a product. The bamboo cylinders are often cracked from the cut portion, but the bamboo cylinder 12 of this embodiment is particularly well-dried by forming the slope 16 on the end side 22 and the cracks are generated from the end side. It is preventing. In addition, since the outer shell 20 is completely removed from the bamboo cylinder 12, the familiarity of the paint is good and the adhesion is strong.
[0021]
Next, a second embodiment of the present invention will be described with reference to FIGS. 6 and 7. The same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. FIG. 6 is a central longitudinal sectional view of the bamboo cylinder 12 subjected to the preliminary process of the present embodiment, and the slope 16 is formed on the outer surface of the bamboo trunk 14 after the removal of the outer skin so that the central side 30 is lowered. . The slope 16 cuts the conduit 24 obliquely while descending from the end side 22 toward the center side 30. That is, in the preliminary process, the bamboo cylinder 12 is formed into a drum-shaped bamboo cylinder composed of only the bamboo body portion 18, and a number of cut openings 26 of the conduit 24 are exposed on the outer surface of the trunk portion 14. The bamboo cylinder 12 is subjected to a drying process similar to that of the first embodiment, and a finishing process is performed to finish the bamboo cylinder 12 as shown in FIG.
[0022]
Explaining the operation of the second embodiment, the bamboo cylinder 12 subjected to the slope processing is heated in the drying process. Then, as shown in FIG. 6, the residual moisture actively volatilizes from the end face 22 on the end side 22 and the cut opening 26 facing the outside air on the inclined surface 16. The bamboo cylinder 12 of the present embodiment leaves both end portions 22 of the body portion 14 thick so that the material bamboo is sufficiently dried to prevent the occurrence of dry cracks while ensuring the physical strength of the container. Can do.
