Description
【考案の詳細な説明】 〔考案の背景と目的〕 本考案は光フアイバの被覆装置に関する。[Detailed explanation of the idea] [Background and purpose of the idea] The present invention relates to an optical fiber coating device.
光フアイバは、棒状ガラス母材を線引装置によ
り線引きして得られるが、そのままではぜい弱で
あり、しかも表面の微小クラツクが空気中で拡大
成長するという性質があるため、樹脂組成物を外
周に被覆して実用している。 Optical fibers are obtained by drawing a rod-shaped glass base material using a drawing machine, but they are fragile as they are, and micro cracks on the surface tend to expand and grow in the air. It is covered and put into practical use.
この被覆方法として現在多用されているのは、
液状樹脂組成物をポツト（外側容器）に収容し、
このポツト（外側容器）の中央に線引き後の光フ
アイバを挿通することにより、光フアイバに樹脂
組成物を塗布する方法である。 Currently, the most commonly used coating method is:
A liquid resin composition is stored in a pot (outer container),
This is a method of applying a resin composition to the optical fiber by inserting the drawn optical fiber into the center of this pot (outer container).
この方法は光フアイバの線引きと同時に被覆が
でき、しかも光フアイバに無理な応力がかからな
いため優れた方法であるが、線引き速度すなわち
被覆速度を速くしようとすると、光フアイバの挿
通する入口付近の樹脂組成物液面が引き込まれる
ような形で低下し、気泡を抱き込むという現象が
発生する。 This method is an excellent method because it can coat the optical fiber at the same time it is drawn and does not put undue stress on the optical fiber.However, if you try to increase the drawing speed, that is, the coating speed, A phenomenon occurs in which the liquid level of the composition decreases as if being drawn in, trapping air bubbles.
この結果光フアイバ表面に気泡が付着した状態
で、被覆装置から光フアイバが出て来てしまうこ
とがある。 As a result, the optical fiber may come out of the coating device with air bubbles attached to the surface of the optical fiber.
このように光フアイバ表面に気泡が付着してい
ると、機械的特性に著しく劣り、当然所期の被覆
目的を達成しない。 When air bubbles are attached to the surface of the optical fiber, the mechanical properties are significantly deteriorated, and the intended purpose of the coating cannot be achieved.
本考案は斯かる状況に鑑み、前記のような光フ
アイバ表面への気泡付着を抑止した光フアイバ被
覆装置の提供を目的とする。 In view of this situation, the present invention aims to provide an optical fiber coating device that suppresses the adhesion of air bubbles to the optical fiber surface as described above.
本考案者らの検討によれば、前記気泡付着の原
因が、光フアイバの挿通速度に対して樹脂組成物
の移動速度が著しく遅いことにあると考えられ
る。
According to studies by the inventors of the present invention, it is believed that the cause of the bubble adhesion is that the moving speed of the resin composition is significantly slower than the insertion speed of the optical fiber.
そこで樹脂組成物の移動速度を速くするため
に、外側容器（ポツト）の内で液状樹脂組成物内
に埋設する位置に複数の環状体を設け、上部に設
けられた環状体の径を大きく、下部に設けられた
環状体の径を小さくしたものである。 Therefore, in order to increase the moving speed of the resin composition, a plurality of annular bodies are provided in the outer container (pot) at positions to be buried in the liquid resin composition, and the diameter of the annular body provided at the upper part is increased. The diameter of the annular body provided at the bottom is reduced.
本考案の構成を、一実施例を示す図面を参照し
て具体的に説明する。
The configuration of the present invention will be specifically explained with reference to the drawings showing one embodiment.
第１図において、１は光フアイバであり、棒状
ガラス母材を線引きしたものを上から下へ挿通す
る。 In FIG. 1, reference numeral 1 denotes an optical fiber, which is inserted through a drawn rod-shaped glass base material from top to bottom.
２は液状樹脂組成物であり、３は液状樹脂組成
物２を収容した外側容器である。 2 is a liquid resin composition, and 3 is an outer container containing the liquid resin composition 2.
外囲器３は光フアイバ１に液状樹脂組成物２を
塗布するため、下部において先細り形状を程して
いる。 The envelope 3 has a tapered shape at the lower part in order to apply the liquid resin composition 2 to the optical fiber 1.
このような外側容器３内には、液状樹脂組成物
２に埋没する位置に複数の環状体４１，４２，４
３が設けられており、この環状体４１，４２，４
３は上部の環状体４１が径が大きく、下部の環状
体４３が径が小さく構成されている。 Inside such an outer container 3, a plurality of annular bodies 41, 42, 4 are placed at positions buried in the liquid resin composition 2.
3 is provided, and these annular bodies 41, 42, 4
3, the upper annular body 41 has a large diameter, and the lower annular body 43 has a small diameter.
第２図は第１図のＡ−Ａ断面図であり、第１図
と同じ符号は同じ構成要素を示す。 FIG. 2 is a sectional view taken along the line AA in FIG. 1, and the same reference numerals as in FIG. 1 indicate the same components.
この環状体４１，４２，４３の存在によつて、
液状樹脂組成物２が光フアイバ１の移動に連れて
移動することを補助する。 Due to the existence of these annular bodies 41, 42, 43,
The liquid resin composition 2 assists in moving along with the movement of the optical fiber 1.
なお、環状体４１，４２，４３は何らかの支持
具５２によりその位置を固定されるものである
が、液状樹脂組成物２の流れを乱さぬよう支持具
５２は細いものがよい。 The positions of the annular bodies 41, 42, and 43 are fixed by some kind of support 52, and the support 52 is preferably thin so as not to disturb the flow of the liquid resin composition 2.
以上説明したような本考案の被覆装置であれ
ば、複数の環状体によつて液状樹脂組成物の移動
が補助され速やかになるため、光フアイバの挿通
速度との差が小さくなり、気泡の光フアイバへの
付着が抑止される。
With the coating device of the present invention as explained above, the movement of the liquid resin composition is assisted by the plurality of annular bodies and becomes faster, so the difference between the insertion speed of the optical fiber and the optical fiber is reduced, and the light of the bubbles is reduced. Adhesion to the fiber is inhibited.
