- the arcs AB and DC and the arc EG are such that the radius Rc of the arc EG is smaller than the radius Re of the arcs AB and DC.
- FIG. 4A and FIG. 4B wrinkles occur in the reinforcing fiber base sheet 14 when the fiber direction of the planar reinforcing fiber base sheet 14 is aligned with the longitudinal direction of the airfoil 15 having a saddle shape.

- the surface ABCD (see FIG. 4A) of the airfoil 15 is circular from the arcs AB and DC. It is formed by a circular arc that becomes concave toward the EG. Therefore, when the airfoil 15 is viewed from the side, the arc EG is located below the arcs AB and DC. The isolated EG is shorter than the isolated lengths AB and DC. The longitudinal length forming the surface ABCD (see FIG. 4A) of the airfoil 15 becomes longer from the length EG toward the length AB or DC.

- the wrinkles generated in the vicinity of the central portion F′H ′ in the width direction of the reinforcing fiber base sheet 14 are one side A′B ′ (see FIG. 4B) or one side D′ C ′ (see FIG. 4B). It decreases as it approaches (see 4B).
- FIG. 5 shows the reinforcing fiber base sheet 14.
- the upper view is a plan view of the reinforcing fiber base sheet 14, and the lower view is a side view.

- the reinforcing fiber base sheet 14 since the reinforcing fiber base material has a high elastic modulus, the reinforcing fiber base sheet 14 has a characteristic that it does not expand in the longitudinal direction by the acting force generated by the pressure contact force at the time of lamination.
- the reinforcing fiber base sheet 14 is pressed in the center portion and force is applied in the longitudinal direction of the airfoil 15 (see FIGS. 3A and 3B). Since the continuous fiber bundles 14c and 14e to which the press contact force is not applied are pulled by the tension applied to the reinforcing fiber base sheet 14 with respect to the central continuous fiber bundle 14d to which the press contact force is applied, the airfoil 15 (FIG. 3A and FIG. It is possible to cause a shift in the longitudinal direction of FIG. 3B).

- the motor 9 is operated to rotate the pressure roller shaft 3b.
- the operator moves so as to push the reinforcing fiber base material laminating apparatus 1 in the longitudinal direction of the airfoil 15, and the press roller section 3 a rotates on the airfoil 15. Therefore, the reinforcing fiber base material laminating apparatus 1 can move on the airfoil 15.
- the roll shaft 2b rotates and the reinforcing fiber base material sheet 14 is fed from the sheet roll part 2a to the press roller 3 while applying tension.
- the tension of the reinforcing fiber base sheet 14 fed from the sheet roll portion 2a to the pressure roller 3 is generated by frictional resistance during the rotation of the roll shaft 2b.
- Friction resistance at the time of rotation of the roll shaft 2b is caused by adopting a slide bearing that generates a sliding frictional force by omitting a rolling bearing that smoothly rotates at the connection portion between the roll shaft 2b and the frames 13a and 13b.
- the adhesive is sprayed from the adhesive supply part 7 onto the surface of the reinforcing fiber base sheet 14 wound around the sheet roll part 2a.
- the central portion of the reinforcing fiber base sheet 14 fed out from the sheet roll portion 2a is pressed against the airfoil 15 by the pressing roller 3 and bonded thereto.
- the reinforcing fiber base material laminating apparatus 1 feeds the reinforcing fiber base sheet 14 to the airfoil 15 while applying tension, and presses the reinforcing fiber base sheet 14 against the airfoil 15 while maintaining the tension. Since the reinforcing fiber base sheet 14 is press-contacted by the press roller 3 having a narrower width than the reinforcing fiber base sheet 14, the press-contact portion is restrained at a predetermined position on the airfoil 15.
- the reinforcing fiber sheet Since the portion that has not been press-contacted is not restrained on the airfoil 15, the reinforcing fiber sheet is deformed by the tension between the sheet feeding roller 2 and the press-contact roller 3 and is relatively displaced (shifted) in the tension direction. Therefore, even if the airfoil 15 has a curved surface, the reinforcing fiber base sheet 14 can be laminated without wrinkles so as to follow the airfoil 15. Therefore, the reinforcing fiber base sheet 14 wider than the press roller 3 can be laminated on the airfoil 15 without wrinkling.
- the tension is applied to the reinforcing fiber base sheet 14 by the frictional resistance between the roll shaft 2b of the sheet feeding mechanism 2 and the bearing. Therefore, the tension can be generated without providing a separate mechanism for generating the tension of the reinforcing fiber base sheet 14. Accordingly, tension is generated on the reinforcing fiber base sheet 14 by the simple reinforcing fiber base material laminating apparatus 1 and the sheet is fed out onto the airfoil 15 and pressed onto the airfoil 15 by the press roller 3.
- the fiber substrate laminating apparatus 1 can laminate the reinforcing fiber substrate sheet 14 onto the airfoil 15 without wrinkling.
- the reinforcing fiber base sheet 14 has a tension and is drawn out onto the airfoil 15 and is pressed at the center. Therefore, force is equally applied to the left and right (both sides) of the reinforcing fiber base sheet 14 in which the central portion is pressed. Therefore, it is possible to laminate the reinforcing fiber base sheet 14 with the center portion pressed on the airfoil 15 without wrinkling.
- the reinforcing fiber substrate laminating apparatus 1 includes an adhesive supply unit 7. Therefore, the reinforcing fiber base material laminating apparatus 1 can carry out the bonding together with the feeding of the reinforcing fiber base material sheet 14 onto the airfoil 15, wrinkle stretching, and pressure contact. Therefore, the work efficiency in the reinforcing fiber base material laminating operation can be improved.
- the fiber direction of the reinforcing fiber base sheet 14 is the same as the longitudinal direction of the airfoil 15, when the reinforcing fiber base sheet 14 is press-contacted, the pressed fiber 14d (see the upper diagram of FIG. 5) Although it does not extend in the longitudinal direction, the surrounding fibers 14c and 14e (see the upper diagram in FIG. 5) are not restrained in the longitudinal direction, and can be displaced in the longitudinal direction by tension.
- the reinforcing fiber base material laminating apparatus 1 is provided with a pressure roller portion 3a and a motor 9 for driving the pressure roller portion 3a, and can be moved by manual control by operating the handle 8.
- the apparatus does not require a complicated control mechanism, and the laminating operation of the reinforcing fiber base sheet 14 on the airfoil 15 can be performed by the simple reinforcing fiber base material laminating apparatus 1. Therefore, the lamination work of the reinforcing fiber base sheet 14 for forming the blades of the windmill can be performed with a small number of people, compared with the conventional manual lamination work, and the work load can be reduced and the work efficiency can be improved.

Abstract
Description
特許文献1に開示されている発明は、ロービング材または糸状にした強化繊維基材を積層するものである。
特許文献2には、強化繊維基材をテープ状にしてその強化繊維基材と同じ幅を有するローラによって繊維幅全体を押さえて型上に圧接しながら積層させる装置が開示されているが、シート状の強化繊維基材を積層する具体的な方法等については開示されていない。
特許文献3には、強化繊維基材シートを型上に積層させる門型の装置が開示されているが、装置が大掛かりなため設置コストがかかるという問題があった。
すなわち、本発明の第一の態様は、型上に積層させる強化繊維基材シートを繰り出すシート繰り出し部と、前記型上に前記強化繊維基材シートを圧接させる圧接部と、を有する強化繊維基材積層装置において、前記圧接部は、前記強化繊維基材シートよりも狭い幅を有し、前記シート繰り出し部は、前記圧接部との間で張力を負荷しながら前記強化繊維基材シートを供給することを特徴とする強化繊維基材積層装置である。
なお、強化繊維基材シートとは、ガラス繊維やカーボン繊維等の強化繊維から形成されており、例えば、幅が約1mのシート状の織物をいう。本発明の強化繊維基材積層装置によって型上に強化繊維基材シートを積層させた後、VaRTAM工法等を用いて樹脂を含浸させて硬化させることにより構造部材である複合材(繊維強化プラスチック)が製作される。
なお、「摩擦抵抗」とは、例えば、強化繊維基材シートを繰り出す動きとともに生じる摩擦によって生じる抵抗を意味し、例えば、強化繊維基材シート繰り出し部が、繊維ロールと、ロールの芯あるいはロールの芯内を通した軸を支える軸受とで構成させる場合には、軸受にすべり摩擦力が発生する軸受部材を採用することによって実現することができる。
また、可動部を移動させることにより、繊維シート繰り出し手段や繊維シートロールの交換あるいは圧接部のメンテナンス時に、シート繰り出し部や圧接部を型の長手方向および幅方向に対して直交する垂直方向に移動することができる。したがって、繊維シート繰り出し部や繊維シートロールの交換あるいは圧接部のメンテナンスが容易となる。
また、シート繰り出し部や圧接部を連続的に型の長手方向に移動することができるので、強化繊維基材シートを容易に大型部材の型に積層させることができる。
本発明の第1実施形態に係る強化繊維基材積層装置について図1および図2に基づいて説明する。
本実施形態に係る強化繊維基材積層装置1は、シート繰り出し機構(シート繰り出し部)2と、このシート繰り出し機構2から繰り出された強化繊維基材シート14を翼型(型)15上に圧接する圧接ローラ(圧接部)3とを備えている。
強化繊維基材シート14は、本実施形態にかかる強化繊維基材積層装置1によって翼型15上に積層された後、VaRAM工法等を用いて樹脂が含浸させられて硬化される。これにより、ブレードの腹側と背側との複合材(繊維強化プラスチック)が形成される。ブレードは、このように製作された腹側と背側との複合材を合わせて一体化されることによって形成される。
図4Aに示すように、翼型15の長手方向と強化繊維基材シート14の繊維方向とを同じ方向にする。翼型15の幅方向である円孤AD,BCに強化繊維基材シート14の2辺A’D’,B’C’を合わせるように単純に真上から押さえつけるように積層させる。
強化繊維基材シート14は、例えば、約5mm幅のガラス繊維や炭素繊維等の各連続繊維束14a,14b,14c,・・・が翼型15(図3A及び図3B参照)の長手方向に沿って平行に配列された織物であり、約1mの幅を有している。また、強化繊維基材は高い弾性率を有しているため、強化繊維基材シート14は、積層時の圧接力で発生する作用力では、長手方向に伸張しない特性を有している。
強化繊維基材積層装置1は、手動により操作される。作業者がハンドル8の把持部を把持し、強化繊維基材積層装置1を翼型15の長手方向に押すように移動する。また、モータ9は、圧接ローラ軸3bを回転駆動させるために作動される。これにより、作業者が強化繊維基材積層装置1を翼型15の長手方向に押すように移動するとともに圧接ローラ部3aが翼型15上を回転する。そのため、強化繊維基材積層装置1は、翼型15上を移動することができる。
強化繊維基材積層装置1が翼型15上を移動するとともに、ロール軸2bが回転してシートロール部2aから圧接ローラ3へと強化繊維基材シート14が張力を負荷しながら繰り出される。シートロール部2aから圧接ローラ3へと繰り出された強化繊維基材シート14の張力は、ロール軸2bの回転時の摩擦抵抗により発生される。ロール軸2bの回転時の摩擦抵抗は、ロール軸2bとフレーム13a,13bとの接続部分に回転を円滑にする転がり軸受等を省略し、すべり摩擦力を発生させるすべり軸受を採用することによって生じさせる。
また、シートロール部2aが回転する時には、接着剤供給部7より接着剤がシートロール部2aに巻回されている強化繊維基材シート14の表面に噴射される。シートロール部2aから繰り出された強化繊維基材シート14は、その中央部を圧接ローラ3により翼型15に圧接されるとともに接着させられる。
強化繊維基材積層装置1は、張力を負荷しながら強化繊維基材シート14を翼型15へと繰り出すとともに張力を保持したまま強化繊維基材シート14を翼型15に圧接する。強化繊維基材シート14よりも幅の狭い圧接ローラ3によって強化繊維基材シート14を圧接するので、圧接部分は翼型15上の所定位置に拘束されてしまうが、強化繊維基材シート14の圧接されなかった部分は翼型15上に拘束されないので、シート繰り出しローラ2と圧接ローラ3との間の張力によって強化繊維シートが変形し張力方向に相対的に変位する(ずれる)。そのため、翼型15上が曲面を有する場合であっても、強化繊維基材シート14を翼型15上に倣うようにシワ無く積層することができる。したがって、圧接ローラ3よりも幅広な強化繊維基材シート14を翼型15上へしわなく積層することができる。
なお、本実施形態では型に風車のブレードを形成する翼型15を用いて説明したが、本発明はこれに限定されるものではなく湾曲や屈曲している型であれば良い。これらの型に積層する強化繊維基材としては、ガラス繊維や炭素繊維などが挙げられる。
以下、本発明の第2実施形態について説明する。本実施形態の強化繊維基材積層装置の構成と積層方法は、補助圧接手段を有している点において第1実施形態と相違し、その他は同様である。したがって、同一の構成および積層方法については、同一の符号を付してその説明を省略する。
補助圧接ローラ(補助圧接部)4,5は、複数(例えば、2つ)備えられている。これらの補助圧接ローラ4,5は、補助圧接ローラ部4a,5aと、図示しない補助圧接ローラ軸とを備えている。
フレーム13a,13bから下方に伸びる部材10,11に接続されている補助圧接ローラ軸は、補助圧接ローラ部4a,5aの中心を貫通している。補助圧接ローラ4,5は、圧接ローラ3の両側に設けられ、圧接ローラ3を挟んで翼型15の幅方向に一列になるように均等な間隔を持って設けられている。補助圧接ローラ4,5は、強化繊維基材シート14が翼型15上から剥離しないように強化繊維基材シート14を翼型15上に押圧する。
補助圧接ローラ4,5により、強化繊維基材シート14は、翼型15上に押圧される。したがって、強化繊維基材シート14が翼型15上から剥離することを抑制することができる。
以下、本発明の第3実施形態について説明する。本実施形態の強化繊維基材積層装置の構成および積層方法は、可動部を有し、可動部が翼型の長手方向に沿うように移動される点において第1実施形態と相違し、その他は同様である。したがって、同一の構成および積層方法については、同一の符号を付してその説明を省略する。
アーム手段(可動部)20は、アーム22が接続されているベース21と、シート繰り出し機構2および圧接ローラ3を備えたアーム22とを有している。
ベース21は、ベース部21aと、走行ローラ21bと、モータ(図示せず)とを備えている。走行ローラ21bは、工場内に設けられているレール30上を回動する。ベース部21aには、モータと、図示しない結合部(以下、第1結合部という。)とが設けられている。ベース部21aの第1結合部には、アーム22が接続されている。この第1結合部によりアーム22は、翼型15の幅方向に移動自在とされている。ベース部21aに設けられているモータは、アーム22を移動させる動力源である。このモータは、アーム22を第1結合部により翼型15の幅方向と、後述する第2結合部により翼型15の長手方向および幅方向に対して直交する垂直方向(図7において上下方向)とに移動自在とされる。
アーム部20を備えている強化繊維基材積層装置1は、工場内に設置されたレール30上に備えられている。このレール30近傍には、レール30の延在する方向と翼型15の長手方向とが同じになるように翼型15が設置されている。この翼型15は、積層される面を上方にして据え付けられている。強化繊維基材積層装置1は、作業者によりレール30上を翼型15上の長手方向に移動される。強化繊維基材積層装置1がレール30上を移動するとともに、アーム手段20に設けられているシート繰り出し機構2より強化繊維基材シート14が繰り出される。繰り出された強化繊維基材シート14は、圧接ローラ3により翼型15上に圧接および接着される。アーム部20に設けられているモータによりアーム22を移動させることによって、翼型15上の幅方向の任意の位置に強化繊維基材シート14と圧接ローラ3とを移動させることができる。
シート繰り出し機構2と圧接ローラ3とは、翼型15の長手方向と、翼型15の長手方向および幅方向に対して直交する垂直方向(図7において上下方向)とに移動自在とされる。そのため、湾曲や屈曲した翼型15上に強化繊維基材シート14を積層する場合であっても、アーム部20を移動することにより圧接ローラ3を翼型15上に圧接することができる。したがって、湾曲や屈曲した翼型15上であっても翼型15上から圧接ローラ3が離れることなく強化繊維基材シート14を積層することができる。
また、アーム部20を移動させることにより、強化繊維シートロールの交換、シート繰り出し機構2および圧接ローラ3のメンテナンス時に、シート繰り出し機構2や圧接ローラ3を翼型15の長手方向および幅方向に対して直交する垂直方向(図7において上下方向)に移動することができるため、これらの作業が容易となる。
また、シート繰り出し機構2や圧接ローラ3を連続的に翼型15の長手方向に移動することができるので、強化繊維基材シート14を簡易的に大型の翼型15上に積層させることができる。
また、アーム22は、シート繰り出し機構2と圧接ローラ3とを片持ち支持していると説明したが、フレームを増設して圧接ローラ3の中央位置を支持する形態としても良い。
さらに圧接ローラ3は水平に支持するだけでなく、翼型15形状によっては傾けて支持し作業性を向上させることも可能である。
