AI Technical Summary

Technical Problem

In the existing optical fiber manufacturing process, the pre-processing steps require a long time, resulting in low optical fiber productivity. Furthermore, the power adjustment is unstable, making it difficult to maintain the tension-to-pulling speed ratio at the target value.

Method used

By controlling the power supply to the spinning furnace in the pretreatment process, reducing the ratio of tension to pulling speed T/V along a quadratic function to the target value Ttarget/Vtarget, and performing pretreatment after the positioning process, the control load is reduced.

Benefits of technology

It improves fiber productivity, shortens the time required for tension and pull speed to stabilize at target values, and reduces the frequency of power adjustment and control load.

Abstract

光纤的制造方法具备前处理工序(P2),将在利用纺丝炉(110)对光纤用母材(1P)进行加热并拉出光纤(1)时对光纤(1)施加的张力以及拉取光纤(1)的速度分别设定为T、V,将张力的目标值设定为Ttarget,将速度的目标值设定为Vtarget,在这种情况下,在前处理工序(P2)中,以T / V随着时间的经过而沿着顶点的值是Ttarget / Vtarget的二次函数减少并成为Ttarget / Vtarget的方式向纺丝炉(110)供给电力。
