Abstract

PURPOSE:To prevent an extreme reduction in working property by providing a bobbin selecting means moving means for moving the front end part of a bobbin selecting means along the axial direction of a connecting body in the reverse side direction from the surface regulated by the rotating surface of an optical fiber catching claw toward the reverse side direction, seeing from the handling front side. CONSTITUTION:When either one of two winding bobbin systems 7a, 7b is failed, or a bobbin switching device such as an optical fiber advancing passage moving means 10 is failed, a bobbin selecting means moving means 1 moves all bobbin selecting means 16 to the reverse side from the surface regulated by the rotating surface of optical fiber catching claws 9a, 9b, or the area outside of the optical fiber advancing passage. Therefore, the bobbin selecting means 16 for hindering the wire netting work of optical fiber 15 in unit bobbin winding is excluded from the working space, and consequently, the wire netting work property can be remarkably improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a two-headed optical fiber winding device. In particular, even if one of the two winding bobbin systems that make up the two-head system breaks down or the bobbin switching device breaks down, single bobbin winding is possible without significantly reducing work efficiency. Regarding improvements.

[Conventional technology]

An optical fiber is an optical transmission line in which a core wire made of a double cylinder of quartz with an outer diameter of 125 nm is coated with a plastic coating approximately 6 On thick.

Optical fibers have the following unique properties.

B. Since it is very thin, it is extremely lightweight and easily breaks.

B. Bending with a small radius of curvature (called microbending) causes radiation loss of light and reduces the transmission efficiency of the optical fiber.

C. In the case of metal wires, simply applying a tension that is considered normal will increase the transmission loss of the optical fiber and reduce the transmission efficiency of the optical fiber.

To manufacture an optical fiber, a double cylindrical quartz base material (called a preform) with a diameter of 20 to 60 nm is melted in a melting path, and an optical fiber core with a diameter of 125 nm is passed through a die. Then, the outer periphery of this core wire is coated with a resin in a resin coating bath to produce an optical fiber having a diameter of 25°. This optical fiber is fed out by a capstan.If you use the above-mentioned optical fiber manufacturing equipment, a long length of optical fiber, for example, about 1100k, can be manufactured continuously from a single preform, and it is especially important to pause halfway. This is something that cannot be done. For this reason, it is necessary to continuously wind the manufactured optical fiber.

Therefore, conventionally, an optical fiber winding machine has been directly connected to the above-mentioned optical fiber manufacturing apparatus. In this optical fiber winder, if the two winding bobbins are alternately switched and wound, continuous winding can be carried out extremely efficiently. A winding machine that winds the material by alternately switching between two winding bobbins is called a two-head winding machine.

A two-head optical fiber winding device in which a conventional two-head winder is applied to an optical fiber will be described with reference to FIG. 2.

Referring to FIG. 2, reference numerals 7a and 7b are two winding bobbins, which are supported by two rotationally driven shafts 6a and 6b, respectively. Reference numerals 8a and 8b are two optical fiber capturing rotating bodies adjacent to the bobbins 7a and 7b, respectively, supported by the respective shafts 6a and 6b, and having optical fiber capturing claws 9a and 9b. Reference numeral 10 denotes an optical fiber traveling path moving means, which is disposed in an intermediate region between the two bobbins 7a and 7b, and moves the traveling path of the optical fiber 15 in a direction parallel to the axes 6a and 6b. Reference numeral 16 denotes an optical fiber traveling direction selection means for selecting the feeding direction in which the optical fiber 15 is fed to the bobbins 7a and 7b. 17
is an optical fiber tension control means such as a dancer roller comprising a fixed pulley and a movable pulley.

Next, the operation of the above two-headed optical fiber winding device will be explained.

The optical fiber 15 fed to the optical fiber winding device is wound onto the winding bobbins 7a and 7b via the optical fiber traveling direction selection means 16 while the tension is controlled to be constant by the tension control means 17. When the optical fiber 15 is wound onto the bobbins 7a and 7b, the optical fiber traveling direction selection means 16 reciprocates between the axial ends of the bobbins 7a and 7b in a direction parallel to the axes 6a and 6b. Exercise.

For example, when winding of the bobbin 7a is completed among the two bobbins 7a and 7b and the bobbin 7a is switched to the bobbin 7b, the optical fiber traveling path moving means 10 is moved to its normal position (Fig. (the position shown by the dotted line) in parallel to the axes 6a and 6b, and while pushing the optical fiber 15, reaches the position shown by the solid line in the figure. - On the other hand, the bobbin 7b has already been rotated, and when the optical fiber 15 is pushed to the position shown in the figure,
Optical fiber catching claw 9b engages optical fiber 15.

Then, the optical fiber 15 is wound onto the bobbin 7b, and switching of the winding bobbin is achieved.After one winding is completed, the end of the wound optical fiber 15 is cut off from the bobbin 7a, and it is removed from the shaft 6a. . While winding continues on bobbin 7b, a new bobbin is inserted into shaft 6.
a, and continuous winding onto the bobbin is performed. Note that when the optical fiber traveling direction selection means 16 is switched from the bobbin 7b to the bobbin 7a,
Move to the position indicated by the broken line in the figure.

[The problem that the invention tries to solve! ! ] However, in the above-mentioned two-head optical fiber winding device, if one of the two winding bobbin systems breaks down or if the bobbin switching device such as the optical fiber traveling path moving means breaks down, the system may become unstable. If single bobbin winding is performed using only a conventional winding bobbin system, each time a bobbin is wound up and a new bobbin is replaced, the operator must wire the optical fiber to the new bobbin. This wire hook has the disadvantage that during work, the presence of the winding bobbin system and the optical fiber traveling path moving means during the above-mentioned malfunction will obstruct the work and significantly reduce work efficiency. .

The purpose of the present invention is to eliminate this drawback, and even if one of the two winding bobbin systems that make up the two-head system breaks down or a bobbin switching device such as an optical fiber advancement path moving means breaks down, An object of the present invention is to provide a two-headed optical fiber winding device that enables single bobbin winding without extremely reducing workability.

[Means for Solving the Problems] The above purpose is to provide two shafts (6a

) (6b); and an optical fiber traveling direction that selects the feeding direction of the optical fiber (15) to the bobbins (7a) and (7b). In the two-headed optical fiber winding device having a selection means (16), the bobbin (7)
The bobbin selection means includes the combination of each of a) and (7b) and each of the optical fiber capturing rotating bodies (8a) and (8b), and the optical fiber traveling path moving means (lO). The front end of the bobbin selection means is moved along the axial direction of the combined body toward the rear side when viewed from the handling front side, and the optical fiber catching claws (9a) (9b)
This is achieved by a two-headed optical fiber winding device provided with a bobbin selecting means moving means (1) for moving the bobbin toward the back side from the plane defined by the rotating surface of the bobbin.

[Effect]

In the two-head optical fiber winding device according to the present invention, the bobbin selection means includes a combination of each of the bobbins and each of the optical fiber capturing rotating bodies, and the optical fiber traveling path movement means, and the bobbin selection means movement means. It is provided. If either one of the two winding bobbin systems breaks down or the bobbin switching device such as the optical fiber traveling path moving means breaks down, the bobbin selecting means moving means will switch between the bobbin selecting means and the bobbin selecting means. Since all of the fibers are moved to the back side of the surface defined by the rotating surface of the optical fiber capturing claw, that is, to an area outside the optical fiber traveling path, the wire hanging of the optical fiber during single bobbin winding becomes an obstacle to the work. As a result of the selection means being removed from the working space, the above-mentioned line hanging can be carried out extremely efficiently, and workability can be significantly improved.

[Embodiment] Hereinafter, a two-headed optical fiber winding device according to an embodiment of the present invention will be described with reference to the drawings.

In the figure, 6a and 6b are two rotationally driven shafts arranged parallel to each other, and 7a and 7b are two windings supported on each of the two shafts 6a and 6b. This is a bobbin for taking. 8a and 8b are the above bobbins 7a and 7b
These are two optical fiber capturing rotating bodies adjacent to each of the above, being pivotally supported by each of the above-mentioned shafts 6a and 6b, and having optical fiber capturing claws 9a and 9b. 10 is disposed in the area sandwiched between the two bobbins 7a and 7b, and the optical fiber 1
This is an optical fiber traveling path moving means for moving the traveling path of No. 5 in a direction parallel to the axes 6a and 6b. Reference numeral 1 denotes a bobbin selection means moving means according to the gist of the present invention, which includes three individual moving means (for example, air cylinders) 11a, 11b, 1.

Reference numeral 11a41b denotes an individual moving means that moves the electric motors Ma-Mb that drive each of the above-mentioned shafts 6a and 6b in the axial direction to move each of the above-mentioned shafts 6a and 6b in the axial direction. 11c is an individual moving means for moving the optical fiber traveling path moving means 10 along the axes 6a and 6b. 16 is the above optical fiber 15
This is an optical fiber traveling direction selection means for selecting the feeding direction in which the fiber is fed to the bobbins 7a and 7b. Reference numeral 17 denotes an optical fiber tension control means such as a dancer roller comprising a fixed pulley 171 and a movable pulley 172, for example.

W is the load.

Next, the operation of the two-head optical fiber winding device according to this embodiment will be explained.

engage. The optical fiber 15 is then wound around the bobbin 7b, and bobbin switching is achieved. The end of the wound optical fiber 15 is cut off from the bobbin 7a on which S winding has been completed, and it is removed from the shaft 6a during winding of the bobbin 7b, and a new bobbin is attached to the shaft 6a to perform continuous winding. . Incidentally, when switching from the bobbin 7b to the bobbin 7a, the optical fiber traveling direction selection means 16 moves to the position shown by the broken line in FIG. 1a.

In addition, if one of the two winding bobbin systems, for example, the bobbin 7b system, fails, the combined body of the bobbin 7b and the optical fiber capturing rotating body 8b will be damaged, as shown by the broken line in FIG. 1b. The individual moving means 11b of the bobbin selecting means moving means 1 moves the driving motor together with the axial direction of the above-mentioned assembly from the handling front side to the back side with a handle. Further, the optical fiber traveling path moving means 10 is similarly moved by the individual moving means 11c along the axial direction of the above-mentioned combined body in the rear direction when viewed from the handling front.

Then, the front end of the bobbin selection means comprising the above-mentioned combined body and the above-mentioned optical fiber traveling path moving means 1O is moved toward the back surface from the surface defined by the rotating surfaces of the above-mentioned optical fiber catching claws 9a and 9b. .

In addition, if the bobbin switching device such as the optical fiber traveling path moving means 10 etc. fails, either one of the two above-mentioned combined bodies is switched by the corresponding above-mentioned individual moving means.
Further, the optical fiber traveling path moving means 10 is moved by the above-mentioned individual moving means AE C in the same manner as in the case of the above-mentioned bobbin system failure.

As described above, by moving the bobbin selection means using the bobbin selection means moving means 1, even if one of the two winding bobbin systems breaks down or the bobbin switching device breaks down, the optical fiber can be moved. The wire hook can be wound on a single bobbin without significantly reducing work efficiency.

〔Effect of the invention〕

As explained above, in the two-head optical fiber winding device according to the present invention, the bobbin selection means includes a combination of each of the winding bobbins and each of the optical fiber capturing claws, and an optical fiber traveling path moving means. Then, the front end of the bobbin selection means is moved in the axial direction of the above-mentioned combined body, and is moved towards the back side as viewed from the front side of handling, from the plane defined by the rotating surface of the optical fiber catching claw.
Since the bobbin selection means moving means is provided,
If one of the two winding bobbin systems breaks down or the bobbin switching device breaks down, the above-mentioned bobbin selection means moving means is used to move the combination of the bobbin and the optical fiber catching claw and the optical fiber traveling path. The bobbin selection means comprising the means can be moved to an area out of the optical fiber traveling path.

Therefore, when winding a single bobbin, each time a bobbin is wound up and replaced with a new bobbin, the wire threading of the optical fiber is carried out during work, and the above-mentioned bobbin selection means, which obstructs the work, is eliminated from the work space. 8i4 reduction in work efficiency can be prevented.

Therefore, in the present invention, even if one of the two winding bobbin systems that make up the two-head system breaks down, or the bobbin switching device such as the optical fiber traveling path moving means breaks down, the workability will be extremely reduced. It is possible to provide a two-headed optical fiber winding device that allows winding on a single bobbin without cutting.
