Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は複合材料の補強材として使用される合成繊維，
炭素繊維，ガラス繊維，スチール繊維等を切断する繊維
切断装置に関するものである。The present invention relates to a synthetic fiber used as a reinforcing material for a composite material,
The present invention relates to a fiber cutting device for cutting carbon fiber, glass fiber, steel fiber and the like.
（従来の技術） 従来、補強用短繊維を複合材用樹脂に連続的に混入する
には長繊維を等速で切断しながら複合材用樹脂に定量的
に供給することが行なわれている。(Prior Art) Conventionally, in order to continuously mix reinforcing short fibers into a resin for composite material, long fibers are quantitatively supplied to the resin for composite material while being cut at a constant speed.
かかる装置には従来より繊維の種類に応じて種々の形式
のものが利用されているが、それらのうち代表的なもの
を第１図によって説明する。第１図において長繊維１は

たは喰込む如く、回転胴体５の外周面に配置されてなる
カッターユニットへ供給され刃先とローラー３との接点
で、無緊張で衝撃を伴う押付折りと押付切りとの作用で
切断される。Various types of such devices have been conventionally used according to the type of fiber, and a typical one of them is described with reference to FIG. In FIG. 1, the long fiber 1 is sandwiched between rollers 2 and 3 made of rubber or plastic, and the cutting edge of the cutting tool 4 is arranged on the outer peripheral surface of the rotary body 5 so as to contact with or invade the surface of the roller 3. Is supplied to the cutter unit and is cut at the contact between the blade edge and the roller 3 by the action of pressing folding and pressing cutting with no tension and impact.
（発明が解決しようとする問題点） しかしながらアラミド繊維に代表される高性能繊維はき
わめて切断抵抗が大であり従来のガラス繊維，炭素繊維
等と異なり押付折り、押付切りだけでは容易には切断出
来ない。かかる繊維を前記従来技術で切断するには、よ
り大きな衝撃力と切創力が必要である。(Problems to be solved by the invention) However, high-performance fibers typified by aramid fibers have extremely high cutting resistance, and unlike conventional glass fibers, carbon fibers, etc., they can be easily cut by pressing folding and pressing cutting. Absent. Greater impact and cut forces are required to cut such fibers with the prior art.
その為には、刃物４の刃先のローラー３への喰込量を大
きく、かつ、より鋭利にする必要があるが、そうすると
ローラー３の表面の疵と刃先の損傷が急激に増加し、数
十秒から数分しか繊維切断能力を維持できない。For that purpose, it is necessary to increase the amount of the blade edge of the blade 4 biting into the roller 3 and make it sharper. However, if this is done, the flaws on the surface of the roller 3 and the damage to the blade edge will rapidly increase, and it will increase to several tens. The fiber cutting ability can be maintained only for a few seconds to a few minutes.
そこで発明者は、かかる切断抵抗の大きな繊維の切断に

よる緊張）により発生する。Therefore, the inventor of the present invention has reached the present invention as a result of earnest studies on the cutting of fibers having such a large cutting resistance. That is, in addition to the conventional pressing folding and pressing cutting, a new cutting method was developed in which sliding cutting was performed by sliding the blade while keeping the fiber in a tension state. The tension state of the fiber is, for example, in FIG. 2, the uneven portion 1 of the rollers 10 and 10 '.
When the fibers 1 and 12 mesh with each other, the long fibers 1 supplied by the roller 10 and the nip roller 2 are bent along the uneven shape at the biting part, resulting in a difference in length due to bending (tension due to extension). Occur.
