Description

Guide wheel assembly of optical fiber for producing system

The present invention relates to a guide wheel assembly for an optical fiber manufacturing apparatus, and more particularly, to an improved guide wheel assembly provided in front of a winder for winding an optical fiber manufactured by the optical fiber manufacturing apparatus to provide ease of winding. will be.

An optical fiber refers to a fiber-shaped waveguide for the purpose of light transmission, and synthetic resin and glass are used as raw materials, but glass having good transparency is mostly used.

As shown in FIG. 2, the optical fiber 30 has a central core 31 and has a shape of a double cylinder in which a cladding 32 surrounds the core, and the outside of the optical fiber 30 has an external impact. It is configured to have a coating layer 33 coated with the same material as the synthetic resin to protect from.

Since the diameter of the optical fiber is 100 to several hundred μm and the refractive index of the core portion is higher than the refractive index of the clad portion, light can be focused on the core portion and proceed without falling out.

These optical fibers are free from interference or interference by external electromagnetic waves, are difficult to wire, small, lightweight, and strong in bending, and can accommodate many communication lines in one optical fiber. It is widely used for detectors.

There are various methods of manufacturing such optical fibers such as crucible, external deposition, internal deposition, axial deposition method, and radiation method, but by melting the preform with rods of about 1cm in diameter having the same structure as the optical fiber and stretching them with high heat. Many methods by radiation to obtain optical fiber are adopted.

The optical fiber manufacturing apparatus 35 by radiation as shown above is shown in FIG. 1 and looks at it as follows.

The optical fiber manufacturing apparatus 35 is provided with a base material feeding device 37 for supplying a base material above the draw tower 36 which is constructed to have a predetermined height on the ground, and is supplied from the base material feeding device 37. Furnace (38) for melting the base material and spinning nozzle (39) for spinning the molten base material to a very fine diameter together.

Below the radiation nozzle 39 is provided with a diameter measuring device 40 for measuring the diameter of the optical fiber 30 to be radiated, the optical fiber cooled while passing through the draw tower 36 provided at a predetermined height ( 30) is provided with a coating machine 41 to prevent deterioration and abrasion and the like and to provide ease of winding.

Such an optical fiber manufacturing apparatus is melted in a furnace by drawing a base metal, and is drawn to a small diameter downward through a spinning nozzle, and the optical fiber being drawn is cooled while passing through a draw tower. It is finally wound up by the odor 45.

A guide wheel assembly 50 for guiding the optical fiber 30 is installed in front of the winder 45 so that the winder 45 easily winds the optical fiber 30.

Conventionally, there was a guide wheel in front of the take-up, but it does not have any other function as merely guiding the optical fiber by changing the direction and free rotation of the manufactured optical fiber.

Because of this, the optical fiber located on the guide wheel cannot be maintained by the tensile force due to the pulling force of the winding machine, but the ellipse or the origin of the surface connected to the pulley is deformed, thereby causing a problem in the quality of the wound optical fiber.

In particular, the outer skin of the optical fiber of the surface connected to the guide wheel due to the tensile force is also damaged, which provides a cause of deterioration of the overall quality, making it impossible to use as a communication line in actual use, and improper use for image transmission and detection. There were several problems.

Accordingly, the present invention is invented to solve the above problems, the guide wheel is rotated in a free rotation direction of the optical fiber, that is, the tilting is repeated in a direction perpendicular to the length (axial) direction of the optical fiber connected to the guide wheel The purpose of the optical fiber is to maintain the exact roundness by rolling motion and to contribute to the improvement of the optical fiber quality.

A wheel shaft for installing a rotary shaft 63 having a wheel guide 62 protruding upward in the longitudinal direction of the wheel holding portion 61, the upper wheel of the wheel guide 62 for fixing the guide wheel 60 Install (65).

A pulley 66 is installed at the lower end of the rotary shaft 63 to connect the pulley 67 and the belt 68 installed below the reducer 55 to tilt the wheel guide 62 at a predetermined angle in the forward and reverse directions. To help.

The rim 70 of the guide wheel 60 forms a seating surface 71 on which the guiding optical fiber 30 can be seated, and prevents detachment of the optical fiber 30 on both sides of the seating surface 71. The flange 72 for protruding is formed.

When the guide wheel 60 is tilted on the seating surface 71, the optical fiber 30 has roughness with friction force suitable for rolling motion along the seating surface 71, and the seating surface 71 has a plane 80. ) May be formed into a gentle concave shape 81 or a gentle convex shape 82 so as to increase the cloud motion.

And it will be preferable to reduce the guide wheel 60 to reduce the rotational resistance.

Guide wheel assembly 50 of the present invention as described above;

The optical fiber 30 manufactured by the optical fiber manufacturing apparatus 35 is passed through the guide wheel assembly 50 so that the optical fiber 30 is easily wound up by the winding machine 45.

The optical fiber 30 passing through the guide wheel assembly 50 is located on the seating surface 71 formed on the rim 70 of the guide wheel 60, and the guide wheel (p) is pulled by the winding machine 45. The free rotation of the 60 guides the optical fiber 30.
