テイング装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an optical fiber coating device for coating an optical fiber with a coating material, and in particular to an optical fiber coating device suitable for forming a uniform coating layer. Related to coating equipment.

If the coating layer of the optical fiber is not coated with a uniform thickness, the optical fiber will cause microbending due to external force or temperature change, increasing the optical loss of the optical fiber. Furthermore, in terms of the strength of the optical fiber, if the coating layer is thin in some places, it is likely to break at those places. If a flaw occurs on the surface of the optical fiber before being coated, the mechanical strength of that part will be significantly reduced, so it is necessary to prevent flaws from forming when coating the optical fiber. The uniformity of the coating layer on the optical fiber includes uniformity of the coating layer in the radial direction, uniformity of the coating layer in the axial direction, and uniformity of the adhesion of the coating material to the surface of the optical fiber by preventing air bubbles from being entrained. In particular, uniformity of the coating layer in the radial direction is important. In order to apply the coating material uniformly in the radial direction, it is necessary to pass the optical fiber through the center of the die (also called nozzle) of the coating bath. Therefore, various methods have been proposed for passing the optical fiber through the center of the die without damaging it.

とされるものがある。（例えば、特開昭54−
142320号公報及び特開昭54−28156号公報参照）。 Generally, the position of the coating tank equipped with a die can be adjusted within a plane perpendicular to the axis of the optical fiber, and the position of the preform of the optical fiber can be adjusted within a plane perpendicular to the axis of the coating tank equipped with a die. There are things that are possible. (For example, JP-A-54-
142320 and Japanese Unexamined Patent Publication No. 1983-28156).
また、多重るつぼ形状のダイスを具備する被覆
槽を用いて、光フアイバの軸ずれを逓減させつつ
順次被覆するものも提案されている（特開昭53−
131851号公報参照）。 Furthermore, a method has been proposed that uses a coating tank equipped with multiple crucible-shaped dies to sequentially coat optical fibers while reducing axis misalignment.
(See Publication No. 131851).
しかし、前者の提案は、ダイスを具備する被覆
槽全体や光フアイバのプリフオーム全体を軸直角
面内で位置調整可能とするために、構造が複雑と
なり温度等の外的要因の影響を受けやすいという
問題点があつた。 However, the former proposal requires that the entire coating tank equipped with the die and the entire optical fiber preform be position-adjustable in a plane perpendicular to the axis, making the structure complex and susceptible to external factors such as temperature. There was a problem.
また、後者の提案は、前者の提案のような問題
点がないものの、位置ずれの微調整ができないと
いう問題点があつた。 Further, although the latter proposal does not have the problems of the former proposal, it does have the problem that it is not possible to finely adjust the positional shift.

In order to achieve the above object, the optical fiber coating apparatus of the present invention includes a second coating tank equipped with an alignment die coaxially disposed upstream of a first coating tank equipped with a coating die. In the optical fiber coating device, the space between the first coating material tank and the second coating material tank is sealed, and a communication passage is provided from the inside of the first coating material tank to the inside of the second coating material tank. , and the second coating material tank and the first coating material tank are rotatably connected in a plane perpendicular to the axis, so that the positions of the axes of the coating die and the alignment die change relatively slightly as they rotate.

The space between the first coating material tank and the second coating material tank is sealed, and a communication path is provided from the inside of the first coating material tank to the inside of the second coating material tank. Even if the entrained air enters the first coating material tank, it will return to the second coating material tank through this communication passage, so the tight contact between the optical fiber and the coating resin will be hindered by the entrained air. There is no fear that it will be done. In addition, the second coating material tank and the first coating material tank are rotatably connected in a plane perpendicular to the axis, and the relative positions of the axis of the alignment die and the axis of the coating die change as they rotate. Since it is formed so that the axis changes slightly, it is possible to easily select a point where the axes coincide or are close to each other by simply rotating the second coating material tank and the first coating material tank in a plane perpendicular to the axis. , fine adjustment of alignment becomes possible.
そして、自己潤滑性材料から成る第２の被覆材
槽の調芯ダイスは、光フアイバがこの調芯ダイス
に接触したとしても滑らかな接触となる。 The alignment die of the second coating bath, which is made of a self-lubricating material, provides smooth contact even when the optical fiber comes into contact with the alignment die.

中心に位置させることができる。 Note that even if the alignment die 12 and the optical fiber 8 come into contact with each other due to disturbance or the like while the optical fiber 8 is running, the optical fiber 8 will not be damaged because it is made of Teflon. Furthermore, even if the alignment die 12 is worn out due to contact with bare fibers at the start, alignment performance is maintained unless eccentric wear occurs. Even if eccentric wear occurs, fine adjustment can be made by rotating the second coating material tank 10.
