。Conventionally, an optical fiber winding device, as shown in FIG. 5, is composed of a capstan 1 that takes up the optical fiber 2 at a constant speed, and a winding fi 3 equipped with a bobbin 4.
The optical fiber 2 is taken up at a constant speed by a capstan 1 and wound onto a bobbin 4 of a winder 3.

制御を行っている。In such a winding device, in order to adjust the winding speed, a dancer roller 6 is installed between the capstan 1 and the winder 3, and a detector 7 detects the position of the dancer roller 6 to control the winding speed. The rotational speed of the winding motor 5 is controlled via a device 9.

。However, in the above-mentioned conventional winding device, there is frictional resistance when the dancer roller 6 slides and sliding resistance inside the detector 7, and the dancer roller 6 cannot move the optical fiber 2 unless the sag 8 is made considerably heavy. Since there was no response, the tension of the optical fiber 2 could only be lowered by about 70 to 100 g.
このため、ボビン４に巻取られた光ファイバ２の巻取り
張力が高くなり、ボビン４内で光ファイバ２が圧迫され

以上の長波長域で伝送ロスが異常に上昇するという問題
があった。For this reason, the winding tension of the optical fiber 2 wound around the bobbin 4 increases, and the optical fiber 2 is compressed within the bobbin 4, and abnormal pressure is applied to the optical fiber 2.
There was a problem in that transmission loss increased abnormally in the longer wavelength range.
そこで、この発明は、このような問題点を解消した光フ

A mitigation device was installed.
上記構造の巻取り装置においては、巻取り張力緩和装置
によって、光ファイバが巻取り機のボビンに巻取られる
手前で、光ファイバに外部から巻取り方向のエネルギー

ようになっている。The optical fiber 2 is taken up at a constant speed by a capstan 1, and includes a dancer roller 6 for controlling the winding speed, and a winding tension relaxation device 10 for applying energy in the winding direction.
The material is wound onto a bobbin 4 mounted on a winder 3 via the winder.

ックされ、これによって巻取り速度が制御されている。The dancer roller 6 is provided with a detector 7 for detecting the roller position and a weight 8 that provides a fairly large tension sufficient to cause the dancer roller 6 to slide. The signal from the detector 7 is fed back to the winding remoter 5 via the control device 8, thereby controlling the winding speed.

れるようになっている。The winding tension relieving device 10 is comprised of a speed control motor 11, an electromagnetic clutch 12 that can adjust the transmission torque from the outside, a wheel 13 that applies energy to the optical fiber, and a volume 14 for adjusting the transmission torque. The rotational speed of the speed control motor 1 is controlled by a control bag 29 so that the circumferential speed of the wheel 1a is about 10% faster than the linear speed at that time. Therefore, while the optical fiber 2 is running, this 10% speed difference is absorbed by slipping on the clutch surface of the 1tM1 clutch 12.
