TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical fiber moving device, and more specifically, is mounted on an optical fiber fusion device that abuts and fuses ends of one and the other optical fibers and reinforces the fusion portion after fusion. The present invention relates to an optical fiber moving device that moves an optical fiber so that a twist is not generated in the vicinity of a fused portion when the fused optical fiber is moved from a fusion position to a reinforcement position.
[0002]
[Prior art]
In a conventional optical fiber moving device, when a fused optical fiber is sandwiched and moved from a fusion position to a reinforcement position, the optical fiber is moved by a rotating mechanism. (For example, see Patent Document 1)

[Problems to be solved by the invention]
In the conventional optical fiber moving device, when moving from a fusion work position for fusing optical fibers to a reinforcement work position for attaching a protection member for reinforcement to a fusion portion, a fusion unit is provided by a grip provided on a rotating arm. The optical fiber is moved from the fusion position to the reinforcing position by gripping both ends of the spliced part and rotating the rotating arm. When a stress is generated by rotation in the extra length portion of the optical fiber, a twist is generated in the fused portion or in the vicinity thereof due to the influence, and if the twist is inherently fixed by the protection member, the twist is caused. When optical communication is performed using an optical fiber, there is a problem that communication characteristics are deteriorated in the vicinity of the fusion / reinforcement portion. Also, if the gripping force of the gripping portion is increased to eliminate the effect of the stress accumulated in the extra length, it is difficult to keep the strain generated in the optical fiber by the gripping force or the gripping force on both sides thereof uniform. However, there is a problem that the optical fiber is distorted or twisted due to the difference between the gripping force of the one and the other, and the fused portion is reinforced and fixed while the distortion or torsion is present, so that the communication characteristics are similarly deteriorated. Was.
