Description
本発明は、竹繊維強化材製造装置における刃物と竹との係合削剥構造に関するものである。 The present invention relates to an engagement and peeling structure between a blade and bamboo in a bamboo fiber reinforcing material manufacturing apparatus.
従来より、採取した竹材から竹繊維を製造し、繊維強化プラスチック（ＦＲＰ）その他の繊維強化型複合材料の強化材（強化繊維に同じ）として用いている事が知られている（例えば、特許文献１、２及び３を参照）。
ここでは、強化材としての強度（カーボン繊維に匹敵する）はもとより、焼却が困難なガラス繊維に代えて、麻繊維、竹繊維その他の天然繊維を使用し、繊維強化型複合材料の廃棄処理時の環境負荷を低減する点を求めている。 Here, hemp fiber, bamboo fiber and other natural fibers are used in place of glass fiber, which is difficult to incinerate, as well as strength as a reinforcing material (comparable to carbon fiber). We are looking for ways to reduce environmental impact.
しかしながら、どのような形態の竹繊維を調達できるかという点に問題があり、一概に単繊維であれば強化材として十全であるという訳にもゆかない。単繊維間の結着力を残して利用する為には繊維径が百μｍ程度の繊維束鞘や繊維束の繊維形態も考慮されるからである。 However, there is a problem in what form of bamboo fiber can be procured, and it cannot be said that a single fiber is sufficient as a reinforcing material. This is because a fiber bundle sheath having a fiber diameter of about 100 μm and a fiber form of the fiber bundle are also considered in order to leave the binding force between single fibers.
ところで市場提供されている竹繊維は、一般的には機械的な解繊処理を施すことにより製造されており、概して繊維径が数百μｍを超えるミリ単位のものであり、その剛直性が折損等の欠点となる場合があった。 By the way, bamboo fiber on the market is generally manufactured by applying a mechanical defibration treatment, and the fiber diameter is generally in the millimeter unit exceeding several hundred μm, and its rigidity is broken. In some cases, such a disadvantage occurs.
本発明者らは、古紙等の繊維含有料の粗粉砕から解繊までを効率的に行う解繊装置（粗粉砕装置を含む）や該繊維含有料を主原料とする複合再生成形物の開発に携わってきた。勿論、繊維含有料として竹材も扱ってきている。 The present inventors have developed a defibrating apparatus (including a coarse pulverizing apparatus) that efficiently performs from coarse pulverization to defibration of fiber-containing materials such as waste paper, and composite regenerated molded products using the fiber-containing material as a main raw material. Has been involved in. Of course, bamboo has also been used as a fiber-containing material.
こうしたなかで、繊維径が数百μｍ以下、又は百μｍを超えるミリ単位以下であり、且つ、繊維長が数ミリメートル〜百ミリメートルを確保可能に生理的（機械的）に削剥して得られる竹繊維及びその製造技術を要請されてきた。本発明者らは、この要請に積極的に対応し、且つ、研究開発を推進して本装置を発明し、出願に至ったものである。 Under these circumstances, the bamboo having a fiber diameter of several hundreds μm or less, or a millimeter unit exceeding 100 μm, and obtained by physiologically (mechanically) scraping to ensure a fiber length of several millimeters to one hundred millimeters. Fibers and their manufacturing techniques have been requested. The present inventors responded positively to this demand, and promoted research and development, invented this apparatus, and came to an application.
そこで、上記課題を解決する為に、この発明は繊維径と繊維長を所定寸法に調整確保し、強化繊維として最適な形態を有する竹繊維強化材製造装置における刃物と竹との係合削剥構造を開発・提供する事にある。 Therefore, in order to solve the above-mentioned problems, the present invention ensures that the fiber diameter and the fiber length are adjusted to predetermined dimensions, and the cutting and cutting structure between the blade and the bamboo in the bamboo fiber reinforcing material manufacturing apparatus having the optimum form as the reinforcing fiber. Is to develop and provide
この課題を解決する為の手段として、装置本体に回転手段に従動回転し、強化繊維として最適な竹の長さに適合した所定長さを有する竹繊維削剥用刃物と、刃物の回転軸部の左右対称位置に所定間隔を保ち、且つ、所定寸法下方にずらした位置に案内部をそれぞれ設けて、竹の削剥深さを調整可能に設けた案内部材から成り、且つ、竹繊維削剥時は竹繊維削剥用刃物の回転軸に対し、竹の中心軸を平行、且つ、垂直線上に保ち、竹の外周面を案内部材の案内部に充当し、押圧しながら削剥する事を特徴とするものである。 As a means for solving this problem, a bamboo fiber scraping blade having a predetermined length adapted to the optimum bamboo length as a reinforcing fiber rotated by a rotating means in the apparatus main body, and a rotating shaft portion of the blade It consists of a guide member that maintains a predetermined interval in the left-right symmetric position and that is provided with a guide portion at a position shifted downward by a predetermined dimension so that the cutting depth of the bamboo can be adjusted. It is characterized by keeping the central axis of the bamboo parallel and perpendicular to the rotation axis of the fiber scraping blade, applying the outer peripheral surface of the bamboo to the guide part of the guide member, and scraping while pressing. is there.
この発明の効果として、装置本体に回転手段に従動回転し、強化繊維として最適な竹の長さに適合した所定長さを有する竹繊維削剥用刃物と、刃物の回転軸部の左右対称位置に所定間隔を保ち、且つ、所定寸法下方にずらした位置に案内部をそれぞれ設けて、竹の削剥深さを調整可能に設けた案内部材から成り、且つ、竹繊維削剥時は竹繊維削剥用刃物の回転軸に対し、竹の中心軸を平行、且つ、垂直線上に保ち、竹の外周面を案内部材の案内部に充当し、押圧しながら削剥する事を特徴とする事で、繊維強化型複合材料の強化材として、至適な繊維径及び繊維長の削剥竹繊維を得る事が出来る。しかも、機械的に削剥した後、熱水処理及び／又は揉捻水洗処理を施すので、繊維表面に剛直性の原因となる付着物（重繊維）が残存する事を極力排除できる。とりわけ、繊維強化プラスチック（ＦＲＰ）の強化材として有用である。 As an effect of the present invention, a bamboo fiber scraping blade having a predetermined length adapted to the optimum bamboo length as a reinforcing fiber, which is driven by a rotating means in the apparatus main body, and a bilaterally symmetrical position of the rotary shaft portion of the blade. It consists of a guide member that is provided with guide portions at positions that are kept at predetermined intervals and shifted downward by a predetermined dimension so that the bamboo cutting depth can be adjusted. The fiber reinforced type is characterized by keeping the central axis of the bamboo parallel and perpendicular to the rotation axis, and applying the outer peripheral surface of the bamboo to the guide part of the guide member and scraping it while pressing. As a reinforcing material for the composite material, an exfoliated bamboo fiber having an optimum fiber diameter and fiber length can be obtained. Moreover, since the hot water treatment and / or the sputum water washing treatment is performed after mechanically scraping, it is possible to eliminate as much as possible the deposits (heavy fibers) that cause rigidity on the fiber surface. In particular, it is useful as a reinforcing material for fiber reinforced plastic (FRP).
この発明の最良の形態として、上記構成において、至適な削剥竹繊維は、1ミリメートル以下の断面径で、数ミリメートル〜百ミリメートルの繊維長からなる単繊維、又は、分断された繊維束（維管束鞘ないしは維管束に同じ）である。 As the best mode of the present invention, in the above-described configuration, the optimal scraped bamboo fiber is a single fiber having a cross-sectional diameter of 1 mm or less and a fiber length of several millimeters to hundred millimeters, or a split fiber bundle (fiber bundle). Same as tube bundle sheath or vascular bundle).
又、揉捻水洗処理工程と熱水処理工程の先後を問わない場合がある。又、熱水処理工程を省略し、揉捻水洗処理工程のみを経て、乾燥処理工程へ移行する場合がある。揉捻水洗処理の度合い（処理効果）によって繊維表面について所望の清浄度が確保されれば問題ないからである。 Moreover, there is a case where it does not matter before and after the water washing process and the hot water treatment process. Moreover, a hot water treatment process may be abbreviate | omitted, and it may transfer to a drying treatment process through only the water washing process process. This is because there is no problem as long as a desired cleanliness is ensured for the fiber surface by the degree of water washing treatment (treatment effect).
そこで、この発明の一実施例を図１〜図３に基づいて詳述すると、竹繊維強化材の製造装置において、装置本体（Ｓ）に回転手段（Ｍ）に従動回転し、強化繊維として最適な竹（Ｂ）の長さに適合した所定長さ（Ｌ）を有する竹繊維削剥用刃物（１）と、刃物の回転軸部（１ａ）の左右対称位置に所定間隔（Ｘ）を保ち、且つ、所定寸法（Ｙ）下方にずらした位置に案内部（２ａ）（２'ａ）をそれぞれ設けて、竹（Ｂ）の削剥深さ（Ｔ）を調整可能に設けた案内部材（２）（２'）から成り、且つ、竹繊維削剥時は竹繊維削剥用刃物（１）の回転軸（１ａ）に対し、竹（Ｂ）の中心軸（Ｂａ）を平行、且つ、垂直線上に保ち、竹の外周面（Ｂｂ）を案内部材（２）（２'）の案内部（２ａ）（２'ａ）に充当し、押圧しながら削剥する事を特徴とする竹繊維強化材製造装置における刃物と竹との係合削剥構造から構成される。 Therefore, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.
