Description

この発明は、撥水や表面強度向上を目的に糸状繊維質体の表面に樹脂液を含浸しこれを熱風等により乾燥し表面樹脂硬化層を形成する製造工程に属するもので、特に樹脂液の含浸層が円周面に均一に形成され、かつ樹脂液の含浸量の調整ができるようにした樹脂含浸装置に関するものである。   The present invention belongs to a manufacturing process in which a surface of a filamentous fibrous body is impregnated with a resin liquid for the purpose of water repellency and surface strength improvement, and this is dried with hot air to form a surface resin cured layer. The present invention relates to a resin impregnation apparatus in which an impregnation layer is uniformly formed on a circumferential surface and the amount of resin liquid impregnation can be adjusted.

従来の樹脂含浸装置としては、繊維製シート材の両面に樹脂液を含浸させるものがある（例えば、特許文献１参照）。図６は従来の樹脂含浸装置を示す概略断面図である。同図において、３１はシート材、３２は樹脂液浸漬槽、３３はディップロール、３４ａと３４ｂはスクイズロール、３５はスクイズロール間隙量調整機構である。この装置では、シート材３１が前工程の巻出装置（図示せず）から連続的に送り出され、ディップロール３３を介して樹脂液浸漬槽３２を通過することによりシート材３１表面に樹脂液を付着する。シート材３１が上方へ走行する途中にてスクイズロール３４ａ、３４ｂがシート材３１を両側から挟み、シート材３１に付着した余分な樹脂液３６ａを絞り落とす。スクイズロール３４ａ、３４ｂの表面に付着した樹脂液３６ｂはブレード３７ａ、３７ｂにて掻き落とす。シート上の樹脂含浸量の調整はスクイズロール３４ａ、３４ｂの間隙を変更するスクイズロール間隙量調整機構３５の動作にて行う。   As a conventional resin impregnation apparatus, there is an apparatus that impregnates both sides of a fiber sheet material with a resin liquid (for example, see Patent Document 1). FIG. 6 is a schematic sectional view showing a conventional resin impregnation apparatus. In the figure, 31 is a sheet material, 32 is a resin solution immersion tank, 33 is a dip roll, 34a and 34b are squeeze rolls, and 35 is a squeeze roll gap adjustment mechanism. In this apparatus, the sheet material 31 is continuously fed from an unwinding device (not shown) in the previous process, and passes through the resin liquid immersion tank 32 via the dip roll 33, whereby the resin liquid is applied to the surface of the sheet material 31. Adhere to. While the sheet material 31 is traveling upward, the squeeze rolls 34a and 34b sandwich the sheet material 31 from both sides, and squeeze out the excess resin liquid 36a adhering to the sheet material 31. Resin liquid 36b adhering to the surfaces of squeeze rolls 34a and 34b is scraped off by blades 37a and 37b. The resin impregnation amount on the sheet is adjusted by the operation of the squeeze roll gap amount adjusting mechanism 35 that changes the gap between the squeeze rolls 34a and 34b.

また、図７は糸状繊維質体８に関しての従来技術の樹脂含浸装置を示す概略斜視図である。シート材の場合と同様に糸状繊維質体８が前工程の巻出装置（図示せず）から連続的に送り出され、サポートロール３８ａ、３８ｂとディップロール３３を介して樹脂液浸漬槽３２を通過することにより糸状繊維質体８の表面に樹脂液を塗布する。樹脂液浸漬槽３２の直後に、搬送される糸状繊維質体８を挟むようにエアーナイフノズル３９ａ、３９ｂを配置しエアーナイフの空気流４０を吹きつけ、エアーナイフの空気流の強弱により樹脂液の拭き取り量を変化させ、樹脂含浸量の調整を行うものである。   FIG. 7 is a schematic perspective view showing a conventional resin impregnation apparatus for the filamentous fibrous body 8. As in the case of the sheet material, the filamentous fibrous body 8 is continuously fed from the unwinding device (not shown) in the previous process, and passes through the resin liquid immersion tank 32 via the support rolls 38a and 38b and the dip roll 33. By doing so, the resin liquid is applied to the surface of the filamentous fibrous body 8. Immediately after the resin liquid immersion bath 32, air knife nozzles 39a and 39b are arranged so as to sandwich the fibrous fibrous body 8 to be conveyed, and an air flow 40 of the air knife is blown. The amount of wiping is changed to adjust the resin impregnation amount.

特開平１０−２４４１３号公報Japanese Patent Laid-Open No. 10-24413

糸状繊維質体表面に形成する樹脂含浸量は規定値があり、一般に製造品種により規定値が変化する。さらに、同一品種のものであっても糸状繊維質体の製造ロット違い等の素材の状態、温度・粘度等の樹脂液の状態、温湿度等の周囲環境状態等の変化により、樹脂含浸装置の樹脂液塗布条件を変更調整する必要がある。つまり、糸状繊維質体の品種、製造条件に応じて糸状繊維質体表面の樹脂含浸量が規定値になるように、樹脂含浸装置において樹脂含浸量の調整機能が必要である。   The amount of resin impregnation formed on the surface of the filamentous fibrous body has a specified value, and generally the specified value varies depending on the production type. Furthermore, even if they are of the same product type, due to changes in the state of the material such as different production lots of the filamentous fibrous body, the state of the resin liquid such as temperature and viscosity, the ambient environment state such as temperature and humidity, etc. It is necessary to change and adjust the resin liquid application conditions. That is, the resin impregnation apparatus needs to have a function of adjusting the resin impregnation amount so that the resin impregnation amount on the surface of the filamentous fibrous body becomes a specified value according to the type and manufacturing conditions of the filamentous fibrous body.

図６の従来技術を糸状繊維質体８の製造に適用する場合は、図８に示すように、スクイズロール３４ａ、３４ｂの円周表面上に円弧形状の溝４１を設け、対向する２本のスクイズロール３４ａ、３４ｂの溝４１の間に糸状繊維質体８を通過させ、樹脂液浸漬槽３２で付着した余分な樹脂液３６ａの絞り落としを行う。しかし、糸状繊維質体８の円周表面に均一な樹脂含浸量の変更調整はスクイズロール３４ａ、３４ｂの間隙量の変更ではできず、スクイズロール３４ａ、３４ｂの円弧形状溝４１の径の大きさをその都度替える必要がある。すなわち円弧形状溝４１の径の大きさの異なる多数のスクイズロールを予め準備しておき、樹脂含浸量の調整の都度、樹脂含浸装置においてスクイズロールの入れ替え調整作業を行うことになり、装置費用が大きくなると共に、著しく生産性が低下する問題がある。   When the prior art of FIG. 6 is applied to the production of the filamentous fibrous body 8, as shown in FIG. 8, an arc-shaped groove 41 is provided on the circumferential surface of the squeeze rolls 34a and 34b, and two opposing faces are provided. The fibrous fibrous body 8 is passed between the grooves 41 of the squeeze rolls 34a and 34b, and the excess resin liquid 36a adhering in the resin liquid immersion tank 32 is squeezed down. However, the adjustment of the uniform resin impregnation amount on the circumferential surface of the filamentous fibrous body 8 cannot be performed by changing the gap amount between the squeeze rolls 34a and 34b, but the diameter of the arc-shaped groove 41 of the squeeze rolls 34a and 34b. Must be changed each time. That is, a large number of squeeze rolls having different diameters of the arc-shaped grooves 41 are prepared in advance, and each time the resin impregnation amount is adjusted, the squeeze roll replacement adjustment work is performed in the resin impregnation apparatus, and the apparatus cost is reduced. There is a problem that productivity increases significantly as the size increases.

また、図７の従来技術では、糸状繊維質体８の配置に対して二方向からエアーナイフの空気流４０を当てる為、糸状繊維質体８の円周方向に均一に樹脂液量の拭き取り調整を行うことは困難である。さらに、エアーナイフの空気流４０により飛散する樹脂液ミストを回収する排気装置およびミスト分離装置が別途必要になる。   Further, in the prior art of FIG. 7, since the air flow 40 of the air knife is applied from two directions to the arrangement of the filamentous fibrous body 8, the wiping adjustment of the resin liquid amount is uniformly performed in the circumferential direction of the filamentous fibrous body 8. Is difficult to do. Further, an exhaust device and a mist separation device for collecting the resin liquid mist scattered by the air flow 40 of the air knife are separately required.

また、図６、図７の従来技術では、糸状繊維質体８が樹脂液浸漬槽３２を通過する際に、ディップロール３３、サポートロール３８ａ、３８ｂが糸状繊維質体８を支持する為、糸状繊維質体８が屈曲した状態で搬送される。最終製品として糸状繊維質体８の断面形状が円形であることを求める場合には、このような搬送では糸状繊維質体８の形状が楕円状に変形してしまい、製品としての品質面の問題がある。   6 and 7, since the dip roll 33 and the support rolls 38 a and 38 b support the fibrous fibrous body 8 when the fibrous fibrous body 8 passes through the resin liquid immersion bath 32, The fibrous body 8 is conveyed in a bent state. When it is required that the cross-sectional shape of the filamentous fibrous body 8 is a circular shape as a final product, the shape of the filamentous fibrous body 8 is deformed into an ellipse by such conveyance, and this causes a quality problem as a product. There is.

この発明は従来技術における以上の諸問題を解決する為になされたもので、糸状繊維質体の円周面に均一に樹脂液を含浸することが可能であって、しかも樹脂含浸量の調整が低コストでかつ容易に行え、さらに断面の円形形状を変形させない樹脂含浸装置を提供するものである。   The present invention has been made to solve the above-described problems in the prior art. It is possible to uniformly impregnate the circumferential surface of the filamentous fibrous body with the resin liquid, and to adjust the resin impregnation amount. It is an object of the present invention to provide a resin impregnation apparatus which can be easily performed at low cost and does not deform the circular shape of the cross section.

Threaded resin solution immersion tank and thread-like fibrous body entrance / exit portions are provided on the side parts arranged opposite to each other, and are conveyed in the resin solution immersion tank and attached to the surface with excess resin liquid And a vacuum dehydration chamber in which the fibrous body is conveyed linearly, and the vacuum dehydration chamber wipes off an excessive resin liquid adhering to the surface of the filamentous fibrous body by an air knife action at an inlet / outlet portion by air suction.

この発明の請求項２に係る樹脂含浸装置は、請求項１において、樹脂液浸漬槽は、液槽内の容積が可変な構造であり、その容積を変更することにより糸状繊維質体表面の樹脂含浸量の調整を行うものである。   The resin impregnation apparatus according to claim 2 of the present invention is the resin impregnation tank according to claim 1, wherein the resin liquid immersion tank has a structure in which the volume in the liquid tank is variable, and the resin on the surface of the filamentous fibrous body can be changed by changing the volume. The amount of impregnation is adjusted.

この発明の請求項３に係る樹脂含浸装置は、請求項１において、減圧脱水チャンバーの入出口部は、吸引エアーナイフの強度の変更により樹脂液の拭き取り量の調整を行ない、糸状繊維質体表面の樹脂含浸量の調整を行うものである。   According to a third aspect of the present invention, there is provided the resin impregnation apparatus according to the first aspect, wherein the inlet / outlet portion of the vacuum dehydration chamber adjusts the amount of wiping of the resin liquid by changing the strength of the suction air knife, and the surface of the filamentous fibrous body The resin impregnation amount is adjusted.

この発明の請求項４に係る樹脂含浸装置は、請求項３において、減圧脱水チャンバーの入出口部は、円錐形部と円筒形部からなるノズル形状の孔であり、糸状繊維質体の円周面に均等にエアーナイフの空気流が作用するものである。   According to a fourth aspect of the present invention, there is provided the resin impregnation apparatus according to the third aspect, wherein the inlet / outlet portion of the vacuum dehydration chamber is a nozzle-shaped hole comprising a conical portion and a cylindrical portion, and the circumference of the filamentous fibrous body The air flow of the air knife acts evenly on the surface.

この発明の請求項５に係る樹脂含浸装置は、請求項３において、減圧脱水チャンバーは、水平方向に多数の糸状繊維質体を通過させるものであり、幅方向に複数の排気口と各々の排気量を調整するダンパーが設けられ、各排気口の風量調整により前記減圧脱水チャンバーの各孔の空気流の強度が均一になるように調整するものである。   The resin impregnation apparatus according to claim 5 of the present invention is the resin impregnation device according to claim 3, wherein the vacuum dehydration chamber allows a large number of filamentous fibrous bodies to pass in the horizontal direction, and includes a plurality of exhaust ports in the width direction and respective exhausts. A damper for adjusting the amount is provided, and the air flow intensity at each exhaust port is adjusted so that the strength of the air flow in each hole of the vacuum dehydration chamber becomes uniform.

この発明によれば、樹脂液浸漬槽の側面部に糸状繊維質体を通す孔を配し、糸状繊維質体を直線搬送することにしたので、糸状繊維質体の断面形状の円形を変形させることがない。また、樹脂液浸漬槽の側板位置を変更することにより糸状繊維質体が樹脂液に接する時間を調整し、糸状繊維質体表面における樹脂液の含浸量の調整を行うことができる。   According to this invention, since the hole for passing the filamentous fibrous body is arranged on the side surface portion of the resin liquid immersion tank and the filamentous fibrous body is conveyed linearly, the circular shape of the cross-sectional shape of the filamentous fibrous body is deformed. There is nothing. Further, by changing the position of the side plate of the resin liquid immersion tank, the time for which the filamentous fibrous body is in contact with the resin liquid can be adjusted, and the amount of impregnation of the resin liquid on the surface of the filamentous fibrous body can be adjusted.

また、樹脂液付着後の糸状繊維質体は減圧脱水チャンバー側面の円錐形状部と円筒形状部からなるノズル形状の孔を通過することにしたので吸引エアーナイフの作用により、糸状繊維質体の円周面に均一に樹脂含浸量の調整ができる。また樹脂含浸量の調整は排気装置の風量調整で簡単に行うことができる為、装置の調整作業による生産性の低下が小さい。   In addition, since the filamentous fibrous body after adhering the resin liquid passes through a nozzle-shaped hole made up of a conical portion and a cylindrical portion on the side surface of the vacuum dehydration chamber, the filamentous fibrous body circles due to the action of the suction air knife. The resin impregnation amount can be adjusted uniformly on the peripheral surface. In addition, since the resin impregnation amount can be easily adjusted by adjusting the air flow rate of the exhaust device, the decrease in productivity due to the adjustment operation of the device is small.

また、排気ファンの風量変化で樹脂含浸量の調整を行う装置であること、エアーナイフを発生させる機能と飛散する樹脂液ミストを回収する機能を同一の送風ファン、ダクトにて実現することから、装置費用が小さくて済む。   In addition, since it is a device that adjusts the resin impregnation amount by changing the air volume of the exhaust fan, the function to generate the air knife and the function to collect the scattered resin liquid mist are realized with the same blower fan and duct, Equipment cost is small.

次に、樹脂液１１を表面に付着した糸状繊維質体８は減圧脱水チャンバー２の側面部のノズル孔２０ａと２０ｂを通過する。排気装置４により減圧脱水チャンバー２内の空気の排気を行い、減圧状態にすることにより減圧脱水チャンバー２の外部から減圧脱水チャンバー入口と出口のノズル孔２０ａと２０ｂに空気流２５が発生する。ノズル孔部のノズル形状の円錐形状部２１から円筒形状部２２へ流入する空気流２５は吸引エアーナイフとして糸状繊維質体８の円周方向に均等に作用し、余分な樹脂液の拭き取りを行う。吸引エアーナイフの強度の変更により、樹脂液の拭き取り量の調整を行い、糸状繊維質体８表面の樹脂液の含浸量の調整を行うことができる。吸引エアーナイフの強度の変更は、排気装置４であるインバーターにより回転数を変更できる排気ファンの風量調整により容易に行うことができる。   Next, the filamentous fibrous body 8 having the resin liquid 11 attached to the surface thereof passes through the nozzle holes 20 a and 20 b on the side surface of the vacuum dehydration chamber 2. By evacuating the air in the vacuum dehydration chamber 2 by the exhaust device 4 and setting the vacuum state, an air flow 25 is generated from the outside of the vacuum dehydration chamber 2 to the nozzle holes 20a and 20b at the inlet and outlet of the vacuum dehydration chamber. The air flow 25 flowing into the cylindrical portion 22 from the nozzle-shaped conical portion 21 of the nozzle hole portion acts equally as a suction air knife in the circumferential direction of the filamentous fibrous body 8, and wipes off the excess resin liquid. . By changing the strength of the suction air knife, the wiping amount of the resin liquid can be adjusted, and the impregnation amount of the resin liquid on the surface of the filamentous fibrous body 8 can be adjusted. The strength of the suction air knife can be easily changed by adjusting the air volume of the exhaust fan whose rotational speed can be changed by an inverter that is the exhaust device 4.

排気装置４は、排気ファンの作用により減圧脱水チャンバー２内の樹脂液ミストを含む空気を外部へ排出する。その際、排気ファンと減圧脱水チャンバー２の中間に配置する樹脂液ミスト分離装置３により、樹脂液ミストと空気は分離し、空気のみを排気ファンから排出することができる。   The exhaust device 4 discharges the air containing the resin liquid mist in the vacuum dehydration chamber 2 to the outside by the action of the exhaust fan. At that time, the resin liquid mist and air are separated by the resin liquid mist separation device 3 disposed between the exhaust fan and the vacuum dehydration chamber 2, and only air can be discharged from the exhaust fan.

減圧脱水チャンバー２は水平方向に多数の糸状繊維質体８を通過させるものであるが、幅方向（長手方向）に複数ある排気口２３のダンパー２４の絞り設定により各排気口の風量調整を行い、減圧脱水チャンバー２の各孔２０ａ、２０ｂの空気流２５によるエアーナイフの強度が均一になるように調整することができる。   The vacuum dehydration chamber 2 allows a large number of filamentous fibrous bodies 8 to pass through in the horizontal direction, and adjusts the air volume of each exhaust port by setting the throttle 24 of the exhaust ports 23 in the width direction (longitudinal direction). The strength of the air knife by the air flow 25 in each hole 20a, 20b of the vacuum dehydration chamber 2 can be adjusted to be uniform.

減圧脱水チャンバー２と樹脂液ミスト分離装置３の下部の溜まった樹脂液は液送ポンプ１７ｃ、１７ｄにより配管１８ｃ、１８ｄを通してサービスタンク１９へ回収する。サービスタンク１９では樹脂液の粘度調整装置と温度制御装置により、粘度と温度を一定に保つ働きを行う。   The resin liquid accumulated in the lower part of the vacuum dehydration chamber 2 and the resin liquid mist separation device 3 is recovered to the service tank 19 through the pipes 18c and 18d by the liquid feed pumps 17c and 17d. The service tank 19 performs a function of keeping the viscosity and temperature constant by a resin liquid viscosity adjusting device and a temperature control device.

この発明の樹脂含浸装置は以上に説明したように、樹脂液浸漬槽の側面部に糸状繊維質体を通す孔を配し、糸状繊維質体を直線搬送することにしたので、糸状繊維質体の断面形状の円形を変形させることがない。また、樹脂液浸漬槽の側板位置を変更することにより糸状繊維質体が樹脂液に接する時間を調整し、糸状繊維質体表面における樹脂液の含浸量の調整を行うことができる。   As described above, the resin impregnation apparatus of the present invention has a hole for passing the fibrous fibrous body in the side surface portion of the resin liquid immersion tank and linearly conveys the fibrous fibrous body. The circular shape of the cross-sectional shape is not deformed. Further, by changing the position of the side plate of the resin liquid immersion tank, the time for which the filamentous fibrous body is in contact with the resin liquid can be adjusted, and the amount of impregnation of the resin liquid on the surface of the filamentous fibrous body can be adjusted.

また、樹脂液付着後の糸状繊維質体は減圧脱水チャンバー側面の円錐形状部と円筒形状部からなるノズル形状の孔を通過することにしたので、吸引エアーナイフの作用により、糸状繊維質体の円周面に均一に樹脂含浸量の調整ができる。また樹脂含浸量の調整は排気装置の風量調整で簡単に行うことができ為、装置の調整作業による生産性の低下が小さい。   In addition, since the filamentous fibrous body after adhering the resin liquid has decided to pass through a nozzle-shaped hole composed of a conical portion and a cylindrical portion on the side surface of the vacuum dehydration chamber, the function of the suction air knife causes the filamentous fibrous body to The amount of resin impregnation can be adjusted uniformly on the circumferential surface. Further, since the resin impregnation amount can be easily adjusted by adjusting the air flow rate of the exhaust device, a decrease in productivity due to the adjustment work of the device is small.

また、排気ファンの風量変化で樹脂含浸量の調整を行う装置であること、エアーナイフを発生させる機能と飛散する樹脂液ミストを回収する機能を同一の送風ファン、ダクトにて実現することから、装置費用が小さて済む。   In addition, since it is a device that adjusts the resin impregnation amount by changing the air volume of the exhaust fan, the function to generate the air knife and the function to collect the scattered resin liquid mist are realized with the same blower fan and duct, Equipment cost is small.
