Description
【０００１】
【産業上の利用分野】
本発明は、主に、ガラス繊維を巻き取るのに適した樹脂製の巻き取り用チューブに関するものである。
【０００２】
【従来の技術】
一般に、ガラス繊維は、溶融ガラスを白金製ブッシングの底部に設けられた多数のノズルから引き出すことによって成形され、各ガラス繊維（ガラスフィラメント）の表面には、集束剤が塗布された後、数百〜数千本束ねられて一本のストランドとされてからチューブに巻き取られる。
【０００３】
この種の巻き取りチューブとしては、複数枚の板紙を貼り合わせたチューブや、樹脂製のチューブ等が用いられてきた。
【０００４】
【発明が解決しようとする課題】
しかしながら、板紙を貼り合わせて得られる巻き取りチューブは、ガラス繊維の紡糸工程での吸水や、作業時や搬送時等での取り扱いによる損傷が激しいため、耐久性に乏しく経済的でない。
【０００５】
また、巻き取りチューブ上に巻き取ったガラス繊維を内側から解舒する場合には、チューブを軸芯方向且つ内径方向に変形させて抜き取る必要があるが、樹脂製の巻き取りチューブは弾性が大きいため、軸芯方向且つ内径方向に容易に変形せず、しかもガラス繊維の巻回体に水分が多く含まれていると、チューブにガラス繊維が付着しやすくなる。そのため、チューブをガラス繊維の巻回体から抜き取るのが非常に困難となり、無理矢理抜き取ると、ガラス繊維を破損することがある。
【０００６】
本発明の目的は、耐久性が高く、ガラス繊維の巻回体から容易に抜き取ることができる樹脂製の巻き取りチューブを提供することにある。
【０００７】
【課題を解決するための手段】
本発明の樹脂製の巻き取りチューブは、肉厚が０．５〜１０ｍｍであるチューブの外周表面に、チューブの肉厚に対して５％以上の深さで、軸芯に対する傾きが０±６０°の範囲内である溝が形成されてなることを特徴とする。
【０００８】
【作用】
本発明の樹脂製のガラス繊維巻き取りチューブは、紡糸工程で吸水することがなく、耐久性が高いため経済的である。
【０００９】
また、本発明の樹脂製のガラス繊維巻き取りチューブは、外周表面に、軸芯に対して０±６０°の範囲内である傾きを有する溝が形成されているため、外力を加えた際に、軸芯方向且つ内径方向に容易に変形し、しかも溝によりガラス繊維との接触面積が少ないため、チューブにガラス繊維が付着せず、ガラス繊維の巻回体から容易に抜き取ることができる。即ち、ガラス繊維巻き取りチューブの外周表面に溝があると、溝の最深部でのチューブ肉厚が薄くなるため、外力を加えた際、内径方向に容易に変形する。しかしながら、軸芯に対する溝の傾きが０±６０°の範囲外では、軸芯方向に変形しにくいため好ましくない。尚、この溝は、外力を加えた際に、内径方向に容易に変形する形態であれば、必ずしも直線状に形成されていなくても構わない。
【００１０】
ガラス繊維巻き取りチューブの肉厚は、０．５〜１０ｍｍが好ましい。即ち、肉厚が０．５ｍｍより薄いと、外力を加えなくても、自重で変形するため、円筒形を維持することができず、１０ｍｍより厚いと、重くなって、搬送時の作業性が悪くなるからである。
【００１１】
樹脂としては、ポリエチレン、ポリプロピレン、ポリブチレン等のポリオレフィン、ゴム系のエストラマー、塩化ビニル等が耐久性が高く、溝の成形性が容易であるため好適である。
【００１２】
本発明の巻き取りチューブは、溝がＶ字、Ｕ字あるいは凹の断面形状を有すると、外力を加えた際に、内径方向に容易に変形するため好ましい。
【００１３】
また、本発明のガラス繊維巻き取りチューブは、溝が、外周上に、１〜１０００本、好ましくは２〜５００本形成されてなると、外力を加えた際に、内径方向に容易に変形するため好ましい。即ち、溝が、外周上に存在しないと、外力を加えても、内径方向に容易に変形せず、１０００本を越えると、外力を加えなくても、自重で変形するため、円筒形を維持できなくなるからである。
【００１４】
また、本発明のガラス繊維巻き取りチューブは、溝が、チューブの肉厚に対して、５％以上、好ましくは５〜９９％、さらに好ましいのは２５〜７５％の深さで、且つ、１０〜１００００％、好ましくは１０〜５００％、さらに好ましくは２５〜３００％の幅を有すると、外力を加えた際に、内径方向に容易に変形するため好ましい。即ち、チューブの肉厚に対して、溝の深さが５％より浅いと外力を加えた際に、内径方向に容易に変形せず、また、溝の幅が１０％より小さいと、外力を加えた際に、内径方向に容易に変形せず、１００００％より大きいと、外力を加えなくても、自重で変形するため、円筒形を維持できなくなるからである。
【００１５】
本発明のガラス繊維巻き取りチューブの内表面の形状は、特に制限されないが、内表面に溝等の凹凸が形成されていても構わない。
【００１７】
本発明のガラス繊維巻き取りチューブは、ブロー成型、押出成型、射出成型等で製造され、溝はチューブ成型時に形成されても、あるいはチューブ成型後に形成されても構わない。
【００１８】
【実施例】
図１に、本発明のガラス繊維巻き取りチューブを示す。最大肉厚３ｍｍ、内径３００ｍｍのポリプロピレン製のチューブ１０に、断面形状がＶ字状の溝１１が軸芯と平行に２００本形成されている。図２に示すように、外周表面の溝の形状は、チューブの肉厚Ｔ＝３ｍｍに対して、深さＤ＝２ｍｍ（６７％）、幅Ｗ＝４ｍｍ（１３３％）の形状を有している。
【００１９】
この巻き取りチューブ１０は、紡糸工程で吸水することが無く、耐久性が高く、経済的であり、外力を加えた際に、軸芯方向且つ内径方向に容易に変形した。さらにこのチューブ１０を使用してガラス繊維を巻き取ったところ、チューブ１０にガラス繊維が付着することなくガラス繊維の巻回体から容易に抜き取ることができた。
【００２０】
【効果】
以上説明したように、本発明の樹脂製のガラス繊維巻き取りチューブは、外周表面に、軸芯に対する傾きが０±６０°の範囲内である溝が形成され、外力を加えた際に、軸芯方向且つ内径方向に容易に変形するため、耐久性が高く、ガラス繊維の巻回体から容易に抜き取ることが可能である。

[Industrial application fields]
The present invention mainly relates to a resin-made winding tube suitable for winding glass fibers.
[0002]
[Prior art]
In general, glass fibers are formed by drawing molten glass from a number of nozzles provided at the bottom of a platinum bushing, and after a sizing agent is applied to the surface of each glass fiber (glass filament), several hundreds of glass fibers are applied. -Thousands are bundled into a single strand, and then wound on a tube.
[0003]
As this type of winding tube, a tube in which a plurality of paperboards are bonded together, a resin tube, or the like has been used.
[0004]
[Problems to be solved by the invention]
However, the take-up tube obtained by laminating the paperboard is not economical because it is highly durable due to water absorption during the spinning process of the glass fiber and handling during handling and transportation.
[0005]
Moreover, when unwinding the glass fiber wound on the take-up tube from the inside, it is necessary to deform the tube in the axial direction and the inner diameter direction and pull it out. However, the resin take-up tube has high elasticity. Therefore, when the glass fiber wound body is not easily deformed in the axial direction and the inner diameter direction, and the glass fiber wound body contains a large amount of moisture, the glass fiber tends to adhere to the tube. Therefore, it becomes very difficult to pull out the tube from the wound body of glass fiber, and if it is pulled out forcibly, the glass fiber may be damaged.
[0006]
An object of the present invention is to provide a resin-made winding tube that has high durability and can be easily pulled out from a wound body of glass fibers.
[0007]
[Means for Solving the Problems]
Winding the tube made of the resin present invention, the outer peripheral surface of the tube wall thickness of 0.5 to 10 mm, more than 5% of the depth relative thickness of the tube, the inclination of pairs the axis A groove having a range of 0 ± 60 ° is formed.
[0008]
[Action]
The resin-made glass fiber winding tube of the present invention is economical because it does not absorb water in the spinning process and has high durability.
[0009]
The resin fiberglass winding tube of the present invention, the outer peripheral surface, since the grooves having an inclination in the range of 0 ± 60 ° with the axis is formed, when an external force is applied In addition, the glass fiber is easily deformed in the axial direction and the inner diameter direction, and since the contact area with the glass fiber is small due to the groove, the glass fiber does not adhere to the tube and can be easily extracted from the wound body of glass fiber. That is, when there is a groove on the outer circumferential surface of the glass fiber winding tube, because the tube wall thickness at the deepest portion of the groove becomes thinner, when an external force is applied, is easily deformed in the inner diameter direction. However, when the inclination of the groove with respect to the shaft core is outside the range of 0 ± 60 °, it is not preferable because it is difficult to deform in the axial direction. In addition, this groove | channel does not necessarily need to be formed in linear form, if it is a form which deform | transforms easily to an internal-diameter direction when external force is applied.
[0010]
The thickness of the glass fiber winding tube is preferably 0.5 to 10 mm. That is, if the wall thickness is less than 0.5 mm, it will be deformed by its own weight even if no external force is applied, so that the cylindrical shape cannot be maintained. Because it gets worse.
[0011]
As the resin, polyolefins such as polyethylene, polypropylene, and polybutylene, rubber-based elastomers, vinyl chloride, and the like are preferable because of high durability and easy moldability of the grooves.
[0012]
In the winding tube of the present invention, it is preferable that the groove has a V-shaped, U-shaped or concave cross-sectional shape because it easily deforms in the inner diameter direction when an external force is applied.
[0013]
Moreover, when the glass fiber winding tube of the present invention is formed with 1 to 1000 grooves, preferably 2 to 500 grooves on the outer periphery, it easily deforms in the inner diameter direction when an external force is applied. preferable. That is, if the groove does not exist on the outer periphery, it does not easily deform in the inner diameter direction even if an external force is applied, and if it exceeds 1000, it will be deformed by its own weight even if no external force is applied. Because it becomes impossible.
[0014]
In the glass fiber take-up tube of the present invention, the groove has a depth of 5% or more, preferably 5 to 99%, more preferably 25 to 75%, and more preferably 10% to the thickness of the tube. A width of 10000%, preferably 10% to 500%, more preferably 25% to 300% is preferable because it easily deforms in the inner diameter direction when an external force is applied. That is, when the external force is applied if the groove depth is less than 5% of the wall thickness of the tube, it is not easily deformed in the inner diameter direction, and if the groove width is less than 10%, the external force is not applied. This is because when it is added, it is not easily deformed in the inner diameter direction, and if it is larger than 10000%, it is deformed by its own weight without applying an external force, so that the cylindrical shape cannot be maintained.
[0015]
The shape of the inner surface of the glass fiber winding tube of the present invention is not particularly limited, but irregularities such as grooves may be formed on the inner surface.
[0017]
The glass fiber winding tube of the present invention is manufactured by blow molding, extrusion molding, injection molding or the like, and the groove may be formed at the time of tube molding or after the tube molding.
[0018]
