Description

本発明は、撚りのない連続繊維束を用いた長繊維強化樹脂構造物の製造方法、それに使用する予め逆撚りがかけられた連続繊維束パッケージ、該パッケージを製造するための巻取り装置に関する。   The present invention relates to a method for producing a long fiber reinforced resin structure using a continuous fiber bundle without twisting, a continuous fiber bundle package subjected to reverse twisting for use therein, and a winding device for producing the package.

熱可塑性樹脂を連続繊維で補強した長尺の繊維強化樹脂構造物は、短繊維で補強されたものに比べてはるかに優れた力学的物性を有し、またこれを切断してペレット状等の成形材料とすることもできるなどの利点があるため、近年、特に期待されている。かかる長尺の繊維強化熱可塑性樹脂構造物は一般に連続した強化用繊維束をクロスヘッド押出機を通して引きながら熱可塑性樹脂を含浸した後、ダイを通して引き抜いたり(USP3993726号明細書)、連続した強化用繊維束を引きながら溶融熱可塑性樹脂に浸漬して樹脂を含浸させた後、ダイを通して引き抜いたり(特開昭57−181852号公報)する、いわゆるプルトルージョン法によって製造されており、所望により任意の長さに切断される。   A long fiber reinforced resin structure reinforced with continuous fibers of thermoplastic resin has much better mechanical properties than those reinforced with short fibers. Since there is an advantage that it can be used as a molding material, it has been particularly expected in recent years. Such long fiber reinforced thermoplastic resin structures are generally impregnated with a thermoplastic resin while drawing a continuous reinforcing fiber bundle through a crosshead extruder, and then drawn through a die (USP 3993726) or for continuous reinforcement. It is manufactured by a so-called pultrusion method in which a fiber bundle is drawn and immersed in a molten thermoplastic resin to impregnate the resin, and then drawn through a die (Japanese Patent Laid-Open No. 57-181852). Cut to length.

一方、熱硬化性樹脂を用い、これを連続繊維で強化した構造物もガラスロービング等の繊維に未硬化樹脂を被覆した後、張力を加えながら回転する枠に巻き付けた後に硬化させるいわゆるフィラメントワインディング法や、半硬化状態のプリプレグにするプリフォーミング法、更に異形断面に成形した後完全硬化させるプルトルージョン法など特殊な方法で種々の強化物が製造されている。   On the other hand, a so-called filament winding method in which a thermosetting resin is used and a structure reinforced with continuous fibers is coated with an uncured resin on a fiber such as glass roving and then wound around a rotating frame while applying tension. Various reinforcements are manufactured by special methods such as a pre-forming method for forming a semi-cured prepreg, and a pultrusion method for forming a semi-cured cross-section and then completely curing the prepreg.

かかる繊維強化樹脂構造物の製造において、熱可塑性樹脂あるいは熱硬化性樹脂のいずれを用いた場合にも、連続繊維束にマトリックス樹脂が十分に含浸していることが必要であり、またマトリックス樹脂を均一に含浸させることは、機械的な特性はもちろんのこと、製品の外観上からも重要である。このため、一般には集束された繊維束を張力下テンションバーあるいはロールを通過させることにより開繊して溶融状態あるいは液状の樹脂を含浸させる方法がとられるが、この際、繊維束に撚りがあることは不十分な開繊とこれに伴う不均一な含浸を引き起こすもとになるものであり、また繊維束の開繊工程などにおいて繊維の破断を引き起こす原因にもなるものであり、このような撚りの発生は避けなければならない。   In the production of such a fiber reinforced resin structure, it is necessary that the continuous resin bundle is sufficiently impregnated with the matrix resin when either a thermoplastic resin or a thermosetting resin is used. Uniform impregnation is important not only for mechanical properties but also for the appearance of the product. For this reason, generally, a method is used in which the bundle of bundles is opened by passing it through a tension bar or roll under tension and impregnated with a molten or liquid resin. This is the cause of insufficient fiber opening and the resulting uneven impregnation, and also causes fiber breakage in the fiber bundle opening process, etc. Twisting should be avoided.

ところで、上記のような繊維強化樹脂構造物の製造において、通常使用される強化繊維束は、直径4〜25μmのガラス繊維、炭素繊維、金属繊維、鉱物繊維、有機繊維などのモノフィラメントが適当なサイジング剤で集束され偏平化されたいわゆる連続繊維束パッケージ(ロービングパッケージとも言われる)等として供給される。   By the way, in the manufacture of the fiber reinforced resin structure as described above, the reinforced fiber bundle that is usually used is sized appropriately with monofilaments such as glass fiber, carbon fiber, metal fiber, mineral fiber, and organic fiber having a diameter of 4 to 25 μm. It is supplied as a so-called continuous fiber bundle package (also referred to as a roving package) or the like that is converged and flattened with an agent.

かかるパッケージから繊維束を取り出し樹脂を含浸させるにあたり、パッケージから繊維束を取り出す方法としては、外取り法と内取り法の2つの方法がある。外取り法はパッケージを回転させながらパッケージ外周側から繊維束を取り出す方法であり、繊維束に撚りがかからない利点はあるが、パッケージ自体を回転させるため取り出した繊維束にかかる負担が大きくなり、繊維の破断による毛羽立ちが起こりやすいという問題がある。また取り出される繊維束がパッケージから離れる際に繊維の一部がパッケージ側に残り易く、解舒性が悪いという欠点も有する。   In taking out the fiber bundle from such a package and impregnating the resin with it, there are two methods for taking out the fiber bundle from the package, namely, an outside method and an inside method. The outside method is a method of taking out the fiber bundle from the outer periphery side of the package while rotating the package, and there is an advantage that the fiber bundle is not twisted. However, since the package itself is rotated, the burden on the taken out fiber bundle becomes large, and the fiber There is a problem that fluffing is liable to occur due to breakage. Further, when the fiber bundle to be taken out leaves the package, some of the fibers are likely to remain on the package side, and there is a disadvantage that the unwinding property is poor.

これに対し内取り法はパッケージ内周側から繊維束を取り出す方法であり、取り出した繊維束にかかる負担が軽く、かつ荷崩れおよび汚染防止を兼ねた保護カバーが使用できるため作業性が良い方法とされている。また解舒性も良好である。しかしながら、パッケージを固定させて内周側から繊維束を取り出していくと、繊維束をパッケージ内周に沿って一巻き取り出す毎に必ず一回の撚りが繊維束に加わるという短所を伴う。このように繊維束に撚りが生じることは、前述したように、長繊維強化樹脂構造物の製造において、繊維束の不十分な開繊とこれに伴う樹脂の不十分かつ不均一な含浸の原因になり、また開繊工程等における繊維の破断とこれによる毛羽立ちの原因にもなる。   On the other hand, the inside-out method is a method for taking out the fiber bundle from the inner peripheral side of the package, and the workability is good because the load applied to the taken-out fiber bundle is light and a protective cover that also serves to prevent load collapse and contamination can be used. It is said that. The unwinding property is also good. However, when the package is fixed and the fiber bundle is taken out from the inner circumference side, there is a disadvantage that a twist is always added to the fiber bundle every time the fiber bundle is taken out along the inner circumference of the package. As described above, the twisting of the fiber bundle is caused by insufficient fiber opening of the fiber bundle and accompanying insufficient and non-uniform impregnation of the resin in the production of the long fiber reinforced resin structure. Moreover, it becomes a cause of fiber breakage and fuzz caused by the fiber opening process.

かかる内取り法において、繊維束の撚りを解消させる方法として特開平5−84838号公報には、装置フレームに回転可能に支承されたテーブルと、テーブル中央部に突設された案内ロールと、案内ロールにかかる繊維束の張力を検出するために案内ロールに設けられた張力センサと張力センサで検出した信号に基づいてテーブルを回転させる回転駆動手段を有してなる装置を用い、無心円筒状に巻き取られた強化繊維の内周から円筒外へ巻き出す際して繊維束に生じる張力を検出し、その検出信号に基づいてテーブルを繊維束巻き戻し方向とは逆方向に断続的もしくは連続的に回転させながら連続的に繊維束の取り出しを行う方法が記載されている。(特許文献1参照。)
しかし、該技術は、採用する装置が複雑であり、また複数の筒状繊維束から連続的に取り出す方法とするには改善の余地があった。
In this interior arrangement method, Japanese Patent Laid-Open No. 5-84838 discloses a method of eliminating twisting of a fiber bundle, a table rotatably supported on an apparatus frame, a guide roll protruding from the center of the table, and a guide In order to detect the tension of the fiber bundle applied to the roll, a tension sensor provided on the guide roll and a device having a rotation driving means for rotating the table based on the signal detected by the tension sensor are used to form a centerless cylindrical shape. The tension generated in the fiber bundle when the wound reinforcing fiber is unwound from the inner circumference to the outside of the cylinder is detected, and based on the detection signal, the table is intermittently or continuously in the direction opposite to the fiber bundle unwinding direction. Describes a method of continuously taking out a fiber bundle while rotating it. (See Patent Document 1.)
However, this technique has a complicated apparatus to be employed, and there is room for improvement in a method for continuously taking out a plurality of cylindrical fiber bundles.

さらに内取り法において、繊維束の撚りを解消させる方法として特開平7−205317号公報には、予め一の筒状繊維束パッケージの末端と次に繊維束を取り出す筒状繊維束パッケージの先端とを連結し、前記連結した複数の円筒状繊維束パッケージを回転体に固定し、繊維束の取り出し速度に応じた速度で、かつ取り出し繊維束に生じる撚りを解消する方向に、前記回転体を回転させながら繊維束を取り出す連続的取り出し方法が開示されている。(特許文献2参照。)
しかし、該技術では、パッケージ毎の繊維束の微妙な長さの違いから、連続して製造しているうちに繊維束の径のばらつきが生じ、適切な回転速度がパッケージ毎に異なるため、十分に開繊しないパッケージができるという問題がある。特に、早くに消費したパッケージを繋いだ時には、解舒終了間近のパッケージと混在することとなり、開繊不良が顕著となる。
Further, in the interior arrangement method, as a method for eliminating the twist of the fiber bundle, Japanese Patent Application Laid-Open No. 7-205317 describes in advance the end of one tubular fiber bundle package and the tip of the tubular fiber bundle package from which the fiber bundle is next taken out. And connecting the plurality of connected cylindrical fiber bundle packages to the rotating body, and rotating the rotating body in a direction corresponding to the take-out speed of the fiber bundle and in a direction to eliminate the twist generated in the take-out fiber bundle. A continuous extraction method is disclosed in which a fiber bundle is extracted while the fiber bundle is removed. (See Patent Document 2.)
However, in this technology, due to the subtle difference in the fiber bundle length for each package, the fiber bundle diameter varies during continuous production, and the appropriate rotation speed differs for each package. There is a problem that a package that cannot be opened is formed. In particular, when a package that has been consumed early is connected, it will be mixed with a package that is nearing the end of unwinding, and the opening failure becomes noticeable.

また、特開平10−291832号公報には、第1のストランドの1本乃至複数本と、第1のストランドに比べて番手の小さい第2のストランドの複数本が合糸され、筒状に回巻きされてなるガラスロービングであって、このガラスロービングを使用する際の回巻体内層からの解舒方向と、このガラスロービングを製造する際の第1のストランドの半分以上及び/又は第2のストランドの半分以上のケーキ内層からの解舒方向が逆方向であることを特徴とするガラスロービングが開示されている。
しかし、この技術では、ケーキ(本発明ではパッケージという。)とガラスロービング(本発明ではロービングを連続繊維束という。)の巻き径を調整した上で、ケーキ製造時の撚りを管理する必要があり、通常、所望の撚りが掛けられた連続繊維束パッケージが得られない。
Japanese Patent Laid-Open No. 10-291832 discloses that one or more first strands and a plurality of second strands having a smaller count than the first strand are combined and wound in a cylindrical shape. Wrapped glass roving, the unwinding direction from the wound inner layer when using this glass roving, more than half of the first strand when producing this glass roving and / or the second The glass roving characterized by the unwinding direction from the cake inner layer of more than half of the strand being reverse is disclosed.
However, with this technique, it is necessary to control the twist during cake production after adjusting the winding diameter of the cake (referred to as a package in the present invention) and glass roving (referred to as continuous fiber bundle in the present invention). Normally, a continuous fiber bundle package with a desired twist is not obtained.

撚りがかけられた筒状連続繊維束パッケージを製造するための巻取り装置
図1は、本発明に係る、長繊維強化樹脂構造物製造用の撚りがかけられた筒状連続繊維束パッケージを製造するための巻取り装置Aの一例である。
図1において、4は巻取り芯であり、撚りがかけられた連続繊維束パッケージの柱状の巻取り芯である。柱状は円柱状でも角柱状でもよいが、好ましくは円柱状である。巻取り芯4の形状に応じて筒状連続繊維束パッケージも円筒状や角筒状となるが、好ましくは円筒状である。巻取り芯4は該柱状の巻取り芯の軸4a方向に往復動可能であり、連続繊維束を巻取り芯4上に規則的に配列させて巻取ることができる。なお、撚りがかけられた連続繊維束パッケージが得られた後、巻取り芯4は、そのままでもよいが、内取り式に繊維を引き出す場合には、取り除かれる。

2 is a perforated disk, which is provided coaxially with the axis 4a of the winding core 4 and can be rotated around the winding core 4, and may be a disk or a polygonal disk such as a square, or a column instead of a disk. However, in the present invention, these are referred to as perforated discs.

In principle, when the guide device 3 to which the continuous fiber f 0 without twist is supplied is rotated once in the direction opposite to the rotation direction of the perforated disc 2 and returned to the original position, once in principle. It takes a twist. However, when the perforated disc 2 is rotated once around the winding core 4, the guide device 3 may be somewhat uneven in rotation, so that even if a rotation error of 10% or less, preferably 1% or less occurs. Can be substantially used for the purposes of the present invention.

案内装置3は、一例として、図1に示すように、小円盤3b、小円盤3b上に固定的に設けられた支軸3d及び支軸3dに固定的に設けられたガイド、例えばピンチロール対、3cからなり、小円盤3bがベアリングなどを介して孔空き盤2に対して自由回転可能になるようにしたものでもよい。また、他の一例として、図示しないが、小円盤3bを設けず、ガイド3cの付いた軸3dのみが孔空き盤2に対して自由回転可能になるようにしたものでもよい。   For example, as shown in FIG. 1, the guide device 3 includes a small disk 3b, a support shaft 3d fixedly provided on the small disk 3b, and a guide fixed to the support shaft 3d, for example, a pair of pinch rolls. 3c, and the small disk 3b can be freely rotated with respect to the perforated disk 2 via a bearing or the like. As another example, although not illustrated, the small disk 3b may not be provided, and only the shaft 3d with the guide 3c may be freely rotatable with respect to the perforated disk 2.

なお、本発明に係る巻取り装置は、長繊維強化樹脂構造物製造用の撚りがかけられた筒状連続繊維束パッケージを製造するための巻取り装置であり、実質的に1回の撚りがかかればよいのであるが、必要に応じて、上記案内装置3を自転軸3aの周りに所望の速度で回転させることにより、任意の周期の撚りをかけることができる。
案内装置3を所望の速度で回転させる場合には、単に孔空き盤2によって、自然に自転する他に、自転軸3aを強制回転させるためのモーターなどが設けられる。

Production of Twisted Continuous Fiber Bundle Package A method for producing a twisted continuous fiber bundle package using the winding device shown in FIG. 1 will be described.
An untwisted continuous fiber bundle f 0 supplied from a continuous fiber bundle manufacturing device (not shown) or supplied from a cake wound around a winding core is supplied to the guide device 3 by the direction changing guide 5 or the like. The
The winding core 4 is in a state where it can reciprocate in the axial direction and does not rotate, and the perforated disc 2 is rotated around the winding core 4 in the direction of an arrow, for example. As the perforated disc 2 rotates once, the continuous fiber bundle supplied from the guide device 3 is twisted once and wound on the winding core 4 as a twisted continuous fiber bundle f- 1 . A desired amount of continuous fiber bundles are wound into a continuous fiber bundle package with a core. By removing the winding core 4 from the continuous fiber bundle package with a core, a cylindrical fiber bundle package 1 from which the continuous fiber bundle can be drawn out in an internal manner is obtained. If necessary, tension adjustment may be performed during winding.

長繊維強化樹脂構造物の製造
本発明では、例えば図2に示す装置を用いて、長繊維強化樹脂構造物を製造する。
上記のようにして得られた連続繊維束パッケージ1を、供給台7上に連続繊維束パッケージ1が回転しないように固定する。該固定された連続繊維束パッケージ1から連続繊維束を内取り式に引出すと、撚りが戻されて、撚りのない連続繊維束6が得られるので、これを例えば、開繊装置8などで開繊した後、クロスヘッドダイ式の樹脂含浸装置10に供給し、賦形ダイから樹脂含浸連続繊維束11として引き抜き、所望の温度に冷却して、長繊維強化樹脂構造物を得る。
Production of Long Fiber Reinforced Resin Structure In the present invention, a long fiber reinforced resin structure is produced using, for example, the apparatus shown in FIG.
The continuous fiber bundle package 1 obtained as described above is fixed on the supply base 7 so that the continuous fiber bundle package 1 does not rotate. When the continuous fiber bundle is pulled out from the fixed continuous fiber bundle package 1 in an internal manner, the twist is returned and a continuous fiber bundle 6 without twist is obtained. After fiber finishing, it is supplied to a cross-head die type resin impregnation apparatus 10, pulled out as a resin-impregnated continuous fiber bundle 11 from the shaping die, and cooled to a desired temperature to obtain a long fiber reinforced resin structure.

本発明において用いられる繊維束の繊維の種類としては、特に制約はなく、例えばガラス繊維、炭素繊維、金属繊維、鉱物繊維、超高分子量ポリエチレンや芳香族ポリアミド繊維等の有機物繊維がいずれも使用できる。これらの繊維は、公知の表面処理剤(集束剤)で処理したものであってもよい。   The type of fiber of the fiber bundle used in the present invention is not particularly limited, and for example, any of organic fibers such as glass fiber, carbon fiber, metal fiber, mineral fiber, ultrahigh molecular weight polyethylene and aromatic polyamide fiber can be used. . These fibers may be treated with a known surface treatment agent (sizing agent).

本発明において、前記含浸に用いられる樹脂としては熱可塑性樹脂、熱硬化性樹脂のいずれも使用可能であり、熱可塑性樹脂としては例えばポリエチレン、ポリプロピレン等のポリオレフィン、ポリエチレンテレフタレートやポリブチレンテレフタレート等のポリエステル、ナイロン6、ナイロン66、ナイロン11、ナイロン12、ナイロン610、ナイロン612等のポリアミド、ポリアセタール、ポリカーボネート、熱可塑性ポリウレタン、ポリフェニレンサルファイド、ポリフェニレンオキサイド、ポリスルフォン、ポリエーテルケトン、ポリエーテルアミド、ポリエーテルイミド等のその他の熱可塑性樹脂およびこれらの組み合わせが使用できる。また熱硬化性樹脂としては、例えば不飽和ポリエステル、エポキシ樹脂、熱硬化性ポリウレタン等、あるいはこれらのプレポリマー等が挙げられる。特に得られる長繊維強化樹脂構造物の成形加工が容易な点で熱可塑性樹脂を用いて含浸したものが好ましく、またそのための含浸法としては、操作性の点で含浸ダイ、特にクロスヘッドダイを用いるのが好ましい。   In the present invention, the resin used for the impregnation can be either a thermoplastic resin or a thermosetting resin. Examples of the thermoplastic resin include polyolefins such as polyethylene and polypropylene, and polyesters such as polyethylene terephthalate and polybutylene terephthalate. , Nylon 6, Nylon 66, Nylon 11, Nylon 12, Nylon 610, Nylon 612 and other polyamides, polyacetal, polycarbonate, thermoplastic polyurethane, polyphenylene sulfide, polyphenylene oxide, polysulfone, polyether ketone, polyether amide, polyether imide Other thermoplastic resins such as and combinations thereof can be used. Examples of the thermosetting resin include unsaturated polyester, epoxy resin, thermosetting polyurethane, and prepolymers thereof. In particular, the long fiber reinforced resin structure obtained is preferably impregnated with a thermoplastic resin in terms of ease of molding, and as an impregnation method therefor, an impregnation die, particularly a crosshead die, is used in terms of operability. It is preferable to use it.

次に、樹脂の含浸された連続繊維は、通常賦形ダイ等を通すことにより所望の形状、例えばストランド、棒状、リボン状、テープ状、シート状、板状、あるいは特殊形状等に整えられ、引取ロールを用いて引き取られる。引取った長繊維強化樹脂構造物は、そのままの形で、あるいは任意の長さに切断して、例えばペレット等として、成形あるいは他の加工に供することができる。   Next, the continuous fiber impregnated with resin is usually adjusted to a desired shape, for example, a strand, a rod shape, a ribbon shape, a tape shape, a sheet shape, a plate shape, or a special shape by passing a shaping die or the like, Taken over using a take-up roll. The taken-up long fiber reinforced resin structure can be used for molding or other processing as it is, for example, as a pellet or the like after being cut into an arbitrary length.

固定される連続繊維束パッケージの数は複数であってもよく、その場合、それらの筒状繊維束パッケージは、繊維束が取り出される順に、予め、通常筒状繊維束パッケージの外周表面にある繊維束末端と次の取り出しを行う通常筒状繊維束パッケージの内周面にある先端とを連結した状態で固定台に固定される。この連結方法としては、取り出しにより切断しない程度の連結強度を有することが必要であることはいうまでもない。特に長繊維強化樹脂構造物を製造する場合には、通常、取り出された連続繊維を後方から引きながらテンションバーを通過させて開繊し、クロスヘッドダイにより樹脂を含浸させるのであるから、これらの工程を通過する際に切断しない連結強度が必要である。
このような繊維束の連結方法としては、公知の方法が採用される。このような方法としては、例えば特開昭51−19843号公報に記載の圧縮気流を用いて重ね合わせた両繊維束端に抱絡を起こさせるスプライシングエアー方法が挙げられる。これに用いられる装置は、通常エアースプライサーとして知られている。
スプライシングエアー方法はエアージェットの当て方により「接線エアージェット方式」と「直接エアージェット方式」の2通りに大別されるが、本発明においては何れであってもよい。また、本発明においては、使用するエアースプライサーの機種に特に制約はないが、繊維束の端部のスプライシング部分の長さを調節するためのハサミ、エアージェットの吐出圧力および吐出時間の調節機構等を備えた機種が好ましい。
The number of continuous fiber bundle packages to be fixed may be plural. In this case, the cylindrical fiber bundle packages are preliminarily arranged in advance in the order in which the fiber bundles are taken out. The bundle end is fixed to a fixed base in a state where the bundle end and the tip on the inner peripheral surface of the normal cylindrical fiber bundle package to be taken out are connected. It goes without saying that this connection method needs to have a connection strength that does not cause disconnection by removal. In particular, when producing a long fiber reinforced resin structure, the drawn continuous fibers are usually opened by passing through a tension bar while pulling from the rear, and the resin is impregnated with a crosshead die. The connection strength which does not cut | disconnect when passing a process is required.
As a method for connecting such fiber bundles, a known method is employed. As such a method, for example, there is a splicing air method in which entanglement is caused at both ends of the bundles of fibers bundled using a compressed air flow described in JP-A-51-19843. The device used for this is usually known as an air splicer.
There are two types of splicing air methods, “tangential air jet method” and “direct air jet method”, depending on how the air jet is applied, but any method may be used in the present invention. Further, in the present invention, there is no particular restriction on the type of air splicer to be used, but scissors for adjusting the length of the splicing portion at the end of the fiber bundle, a mechanism for adjusting the discharge pressure and discharge time of the air jet, etc. A model equipped with is preferable.

上記で得られた撚りのかかった筒状連続繊維束パッケージ1の1個を、図2(a)に示すような供給台7上に固定された固定用格納具12に収納し、該筒状連続繊維束パッケージ1から内取り式に繊維束を引き出すことにより、撚りが戻されて撚りのない繊維束を、図2(b)に示した樹脂含浸装置10に供給して、溶融した変性ポリプロピレン樹脂を含浸させた。なお、固定用格納具12は、連続繊維束パッケージ1を締め付けずに、供給台7に固定するものである。
詳細には、上記筒状連続繊維束パッケージ1を回転させずに、内周から繊維を引き出し、テンションロールで繊維束が幅13〜15mmに開繊されるようにテンションをかけ、樹脂含浸装置10としてのクロスヘッドダイに導いた。

Example 1
While rotating a pre-sized cake-wrapped continuous fiber bundle composed of 4000 glass filaments having a fiber diameter of 17 μm while freely rotating, the fiber roving is unwound from the outer periphery, and the continuous fiber bundle f 0 without twist is shown in FIG. The twisted continuous fiber bundle f -1 was wound around the core 4 while being twisted once per turn and supplied to the apparatus to obtain a cylindrical fiber bundle package 1. In detail, while applying tension so that the continuous fiber bundle f 0 without twist is not slackened with the tension roll 5, the guide 3c passes through the guide 3c, for example, the roll pair 3c, while the perforated disc 2 makes one round. , The continuous fiber bundle is twisted once, and the twisted continuous fiber bundle f- 1 is wound up, whereby the cylindrical continuous fiber bundle package 1 is obtained.
One of the twisted cylindrical continuous fiber bundle packages 1 obtained as described above is stored in a fixing storage 12 fixed on a supply base 7 as shown in FIG. By pulling out the fiber bundle from the continuous fiber bundle package 1 in a take-off manner, the untwisted and untwisted fiber bundle is supplied to the resin impregnation apparatus 10 shown in FIG. The resin was impregnated. The fixing storage 12 is for fixing the continuous fiber bundle package 1 to the supply base 7 without tightening.
Specifically, without rotating the cylindrical continuous fiber bundle package 1, the fiber is pulled out from the inner periphery, and tension is applied so that the fiber bundle is opened to a width of 13 to 15 mm with a tension roll. Led to a crosshead die.
The modified polypropylene resin melted by the biaxial extruder 9 was supplied from the resin supply port, and merged with the molten resin and impregnated in the crosshead die. It was drawn through a shaping die, shaped so as to have a resin content of 50% by weight, cooled by a cooling device, sent to a pelletizer while being drawn by a take-up device, and cut to a pellet length of about 11 mm.

(Comparative Example 1)
Pellets were produced in the same manner as in Example 1 except that a non-twisted cylindrical continuous fiber bundle package was used for the supply base shown in FIG.

実施例1では、繊維の切り替え要員は1名で、切替のための停止をすることなく、連続した製造が可能であった。
比較例1では、繊維束に逆撚りが掛けられていないため、繊維束の外周を固定して、内取りで繊維を取り出すと、運転開始から1分以内に、取り出されてから樹脂含浸装置に供給されるまでの部分の繊維ロービングに無数の撚りが発生して、樹脂含浸装置中で繊維束を開繊することが困難になり、それにより樹脂含浸が不十分となった。
In Example 1, there was one person for switching fibers, and continuous production was possible without stopping for switching.
In Comparative Example 1, since the fiber bundle is not subjected to reverse twisting, when the outer periphery of the fiber bundle is fixed and the fiber is taken out by internal arrangement, the fiber bundle is taken out to the resin impregnation apparatus within 1 minute from the start of operation. An infinite number of twists occurred in the fiber roving in the portion until being supplied, and it was difficult to open the fiber bundle in the resin impregnation apparatus, and the resin impregnation was insufficient.

実施例1で得られた、撚りのかけられた連続繊維束パッケージ1の3個を、図2(c)に示すように、エアースプライサーにより直列につないだ連続繊維束20系列(図2(c)では図を簡略化するため2系列のみ示している。また、各連続繊維束パッケージ1は自転しないように実施例1と同様にして固定してある。)を、図2(b)に示した樹脂含浸装置10に供給して、溶融した変性ポリプロピレン樹脂を含浸した。
詳細には、上記連続繊維束パッケージ1は回転させずに、内周から繊維を引き、テンションロールで繊維ロービングが幅13〜15mmに開繊するようにテンションをかけ、樹脂含浸装置10としてのクロスヘッドダイに導いた。
二軸の押出機9にて溶融した変性ポリプロピレン樹脂は樹脂供給口から供給され、クロスヘッドダイ内で溶融樹脂と合流し含浸させた。賦形ダイを通して引き抜き、樹脂含量50重量%となるように賦形し、冷却装置により冷却し、引き取り装置にて引きながらペレタイザーに送られ、およそペレット長さ11mmになるようにカッティングした。

As shown in FIG. 2 (c), three continuous fiber bundle packages 1 obtained in Example 1 were connected in series by an air splicer (FIG. 2 (c). 2), only two lines are shown for the sake of simplicity, and each continuous fiber bundle package 1 is fixed in the same manner as in Example 1 so as not to rotate.) Is shown in FIG. Was supplied to the resin impregnation apparatus 10 and impregnated with the molten modified polypropylene resin.
Specifically, the continuous fiber bundle package 1 does not rotate, pulls the fibers from the inner periphery, and tensions the fiber roving with a tension roll so that the fiber roving is opened to a width of 13 to 15 mm. Led to the head die.
The modified polypropylene resin melted by the biaxial extruder 9 was supplied from the resin supply port, and merged with the molten resin and impregnated in the crosshead die. It was drawn through a shaping die, shaped so as to have a resin content of 50% by weight, cooled by a cooling device, sent to a pelletizer while being drawn by a take-up device, and cut to a pellet length of about 11 mm.
Before the continuous fiber bundle of the third cylindrical fiber bundle package 1 was lost, fibers were connected to the cake roving fiber roving in series of three pieces using an air splicer, and the operation was continued. The cylindrical fiber bundle package 1 hung on the crosshead die was implemented in 20 series at a take-up speed of 10 m / min. One person who switched fibers was able to continue operation with plenty of room.

(比較例2)
従来のように、撚りのかかっていない筒状連続繊維束パッケージを使用し、筒状連続繊維束パッケージを自転可能にして、外取り式で取出し、樹脂含浸装置10に供給した以外は実施例1と同様に行った。
筒状連続繊維束パッケージの切替時には、運転を停止して、該筒状連続繊維束パッケージの末端と次の筒状連続繊維束パッケージの取出し開始部分を、エアースプライサーにより連結するために、運転を停止する必要があった。これにより、生産性が低下し、また運転停止・開始時に不良品が発生した。
(Comparative Example 2)
Example 1 except that a cylindrical continuous fiber bundle package that is not twisted is used as in the prior art, the cylindrical continuous fiber bundle package is made to be able to rotate, is taken out in a detached manner, and is supplied to the resin impregnation apparatus 10. As well as.
