- the optical fiber having the coloring layer is thereafter taken up by the capstan roller 32 through several guide ports 34, and the tension is adjusted by the take-up dancer roller 36b to be wound. Take up with take-up reel 3 3
- the cleaning unit 10 when the optical fiber is colored, the cleaning unit 10 is passed before the optical fiber 20 is passed through the coloring die 37. Before the coloring unit 10 is formed on the surface of the optical fiber, the cleaning unit 10 removes foreign substances adhering to the surface of the optical fiber and peels off the colored layer as described with reference to FIGS. 4A to 5B. It is possible to manufacture a colored optical fiber without any. In particular, when a long time has passed since the optical fiber 20 was drawn, there is a possibility that deposits from the protective coating may be deposited on the surface of the optical fiber. It is extremely effective for leaving.
- the cleaning unit 10 is arranged in the coloring device in FIG. 7, the optical fiber is cleaned by the rewinding device in FIG. 6 and once wound on a take-up reel, and then the coloring device in FIG. May be colored.
- the time from the cleaning of the optical fiber to the coloring is long, it is expected that dust and deposits will re-attach, so it is desirable that the time during this time be as short as possible.
- this is an extremely effective method if the workplaces and operators are different. You.
- FIG. 8A is a diagram illustrating an example of installation of a cleaning unit
- FIGS. 8B and 8C are diagrams illustrating another example of installation of a cleaning member.
- reference numeral 14 denotes a support arm
- 15 denotes a mounting head
- the other reference numerals are the same as those used in FIG.
- the cleaning unit 10 holds the cleaning member 11 with a holding frame 12, and holds the holding frame 12 with a support arm 14 in an appropriate position in the traveling path of the optical fiber 20. It is installed in the mechanism part. Further, the cleaning unit 10 may be divided into a plurality of units and provided at a plurality of locations.
- the optical fiber 20 is preferably passed through the central portion of the cleaning member 11, and is physically directly in contact with the optical fiber passing portion H of the cleaning member 11 so that it can be wiped.
- the optical fiber 20 runs on a predetermined pass line with a predetermined tension in a steady state, but the pass line may change due to a change in the optical fiber's line tension or the like.
- the cleaning member 11 may be set at a position where the position of the optical fiber passage portion H of the cleaning member 11 is shifted with respect to the pass line of the optical fiber 20.
- the cleaning member 11 if the cleaning member 11 is attached in a fixed state, the cleaning member 11 does not contact the outer peripheral surface of the optical fiber 20 uniformly, and there is a portion that does not partially contact. As a result, it is expected that the wiping of the surface of the optical fiber will not be performed uniformly, and the removal of foreign matter will be incomplete. Therefore, in the present invention, it is desirable that the position of the optical fiber passage portion H can be adjusted according to the variation of the pass line of the cleaning unit 10 optical fiber 20. In addition, it is desirable that the position of the optical fiber passage portion H is self-aligned and movably held at the position of the normally running optical fiber due to the linear tension of the optical fiber.
- the support arm 14 is moved vertically or vertically so that the contact state with the optical fiber in the optical fiber passage portion H of the cleaning member 11 is maintained at the steady state. Holds cleaning member 1 1 by controlling in the left and right direction
- the position is adjustable.
- the drive control of the support arm 14 can be performed, for example, by detecting a path line of an optical fiber with a sensor or the like.
- the support arm 14 can be provided by using a mechanism that reduces the movement resistance in the vertical direction or the horizontal direction.
- Fig. 8B shows a configuration in which the mounting head 15 for attaching the cleaning member 11 is held with low frictional resistance to the holding frame 12 and can be moved in a self-centering manner by the line tension of the optical fiber.
- the path line of the optical fiber 20 changes from a chain line state to a solid line state due to a change in the line tension or the like of the optical fiber 20.
- the cleaning member 11 can be moved in the radial direction of the optical fiber 20 together with the cleaning member 11 through the optical fiber penetrating portion H, following the linear tension of the optical fiber 20.
- the state of contact with the optical fiber 20 at the optical fiber passage portion H is maintained at the steady state, and a uniform wiping form can be maintained.
- FIG. 8C is a diagram illustrating an example in which a soft and flexible member is used for the cleaning member 11 and an example in which the cleaning member 11 is mounted on the mounting head 15 with its surface having slackness.
- the optical fiber 20 is in frictional contact with the optical fiber passage portion H of the cleaning member 11. Therefore, if the cleaning member 11 is formed of a soft and flexible member such as rubber, for example, the optical fiber passing portion H of the cleaning member 11 is It is stretched and moved in the running direction of the optical fiber due to frictional force. At this time, due to the flexibility of the cleaning member 11, movement in the radial direction is somewhat allowed. As a result, the state of contact with the optical fiber 20 is maintained at the steady state at the optical fiber passage portion H, and a uniform wiping form can be maintained.
- This example is not suitable for a case where the path line of the optical fiber 20 fluctuates greatly. However, it is possible to increase the range of fluctuation by combining with the configuration of FIGS. 8A to 8B.
- the cleaning member 11 may be attached to the attachment head 15 with a slack.
- the state of the optical fiber 20 changes from the state of the dashed line to the state of the solid line.
- the optical fiber passing portion H of the cleaning member 11 becomes loose in the cleaning member 11 so that the optical fiber passing portion H is moved in the traveling direction and the direction. It can be moved relatively easily in the radial direction.
- the contact state with the optical fiber 20 is maintained in the optical fiber transmitting portion H at the steady state, and a uniform wiping form can be maintained.
- This example is not suitable for the case where the path line of the optical fiber 20 fluctuates greatly, but the range of fluctuation can be increased by combining with the configurations of FIGS. 8A to 8B.
