Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filament winding device for winding filaments such as optical fibers on a bobbin in a sequentially aligned state.

[0002]

2. Description of the Related Art For example, an optical fiber is manufactured through a predetermined manufacturing process, wound on a bobbin by a guide roller of a winding device, and stored. The bobbin is composed of a cylindrical body around which an optical fiber is wound and a collar integrally formed on both sides of the body, and is rotatable by a drive motor. Therefore, the optical fibers are wound around the body of the bobbin, which is driven and rotated, in order and aligned.

In this case, it is necessary to wind the optical fiber around the body of the bobbin so that no gap is formed between the adjacent optical fibers. This is so that the optical fibers wound around the bobbin can be smoothly sent out without coming into contact with each other when the optical fibers are sent out again. However, it is difficult to wind the bobbin in a line so that a gap is not formed between adjacent optical fibers only with the guide roller. Therefore, as a device that can be wound on a bobbin in close contact with each other so that there is no space between the adjacent optical fibers, as described in, for example, Japanese Patent Laid-Open No. 4-204.
The one disclosed in Japanese Patent No. 60 has been proposed.

FIG. 9 (a) shows an outline of a conventional optical fiber winding device. As shown in FIG. 9, a bobbin 104 in which flanges 102 and 103 are integrally formed at both ends of a body 101
Is rotatably driven by a drive motor (not shown),
The optical fiber 105 sent through between a pair of guide rollers (not shown) arranged in the axially outer peripheral portion of the bobbin 104 can be wound in line with the barrel 101 of the bobbin 104. It is like this.

A presser roller 106 having a substantially disk shape is arranged around the outer periphery of the bobbin 104, and an engaging groove 107 for the optical fiber 105 is formed on the outer peripheral portion of the presser roller 106 and tapered on both sides thereof. A surface 108 is formed. The pressing roller 106 is rotatably supported by a supporting arm 109 that is movable by a plurality of actuators (not shown), and has an angle of about 45 degrees with respect to the optical fiber winding direction A shown in FIG. 9A. Figure 9
The optical fiber can be held at an angle of about 45 degrees with respect to the winding direction B of the optical fiber shown in (b), and the flange 102 of the bobbin 104,
It is movable between 103 and can be retracted upward from the bobbin 104.

Then, the optical fiber 105 is attached to the bobbin 104.
In order to wind the sheet in an aligned state with no gap, first, the end portion of the optical fiber 105 sent through between the pair of guide rollers is locked to the flange 102 of the bobbin 104, and then the pressing roller 106 is pulled from this state. As shown by the solid line in FIG. 9A, the tapered surface 108 is brought into contact with the body 101 at a predetermined angle and a predetermined pressure is applied to the flange 102 side. Next, when the bobbin 104 is rotated by the drive motor, the optical fiber 105 is wound around the barrel 101 of the bobbin 104 and the engaging groove 107 of the pressing roller 106 is also wound.
Engage with.

When the bobbin 104 is rotated to wind up the optical fiber 105, the optical fiber 105 is pressed against the flange 102 side with a predetermined pressure by the pressing roller 106, so that the optical fiber 105 is aligned on the bobbin 104 without any gap. It will be wound up in the state. Then, as shown by the chain double-dashed line in FIG. 9A, when it comes to a position past the intermediate portion in the axial direction of the body 101, the support arm retracts the pressing roller 106 upward, and this time, as shown in FIG. As shown in b), the taper surface 108 is attached to the flange 1 by inclining it to the opposite side by a predetermined angle.
03, and a predetermined pressure is applied to the flange 103 side.

At this time, the optical fiber 105 is not guided by the pressing roller 106 but is guided only by the guide roller and is wound around the bobbin 104. When the optical fiber 105 is wound up to the flange 103 on the barrel 101 of the bobbin 104, the winding of the next stage is naturally started, and at the same time, the engaging groove 107 of the presser roller 106 is waiting. Engage with. Therefore, similarly to the above, when the bobbin 104 is rotated to wind up the optical fiber 105, the optical fiber 105 is pressed against the flange 103 side with a predetermined pressure by the pressing roller 106, and is wound in an aligned state without a gap. Will be taken. By repeating this, a predetermined amount of the optical fiber 105 is wound around the bobbin 104.

[0009]

In the above-mentioned conventional optical fiber winding device, the pressing roller 106 is arranged in a state in which the pressing roller 106 is tilted at a predetermined angle with respect to the body 101 of the bobbin 104, and is wound around the body 101. By applying a predetermined pressure to the flange 102 or 103 side of the optical fiber 105 to be taken, the optical fiber 10 is applied to the bobbin 104.
5 is wound in an aligned state without a gap. Therefore, the pressing roller 106 can be used from the start of winding of the body 101 on the bobbin 104 to the portion just past the intermediate portion, but at the end of winding, the pressing roller 106 can be used.
And the flange 102 (103) are in contact with each other and cannot be used. Therefore, at the winding end portion of the body 101 of the bobbin 104 where the pressing roller 106 cannot be used, the optical fiber 05 is wound around the bobbin 104 only by the guide roller as in the conventional case. There is a possibility that the 105 may not be aligned without a gap.

The pressing roller 106 is for pressing the optical fiber 105 against the flange 102 or 103 side by the pressing force thereof and winding it in an aligned state without a gap, and it is necessary to support it by a bearing or the like so as not to rattle. .
Therefore, there is a limit to downsizing of the presser roller 106,
When winding a small-diameter optical fiber around a small-diameter bobbin, there is a problem that the above-mentioned conventional optical-fiber winding device cannot be applied.

Further, in the conventional optical fiber winding device, in order to support the pressing roller 106, a supporting arm, a large number of actuators, an air cylinder, etc. are required, which makes the mechanism complicated and expensive. It became a device.

The present invention solves such a problem, and it is possible to reliably wind the optical fibers in an aligned state over the entire area of the bobbin without gaps, and to simplify the apparatus and reduce the cost. It is an object of the present invention to provide a winding device for a linear body.

[0013]

SUMMARY OF THE INVENTION To achieve the above object, a filament winding device according to the present invention is provided on the outer periphery of the winding bobbin within the winding width of the winding bobbin. In a winding device of a linear body, the guide roller of the linear body being positioned reciprocates in the direction of its rotation axis to guide the linear body to the outer periphery of the winding bobbin and the linear body is wound up. The linear member pressing member is provided on the outer periphery of the bobbin so as to act in a direction in which the side surfaces of the linear member already wound are brought into close contact with each other.

Further, in the filament winding device of the present invention, the filament pressing member has a spherical shape having a diameter larger than the diameter of the filament.
The filamentous body is wound around the entire range of the winding width of the winding bobbin and is pushed by the filamentous body so as to be movable to the outside of the winding bobbin.

In the filament winding device of the present invention, the tip of the filament pressing member acts on the side surface of the filament with a predetermined pressure,
The base end is connected to the rotary damper, and is rotatable according to the winding amount of the linear member.

In the filament winding device of the present invention, the filament pressing member is supported by a linear guide which is movable along the direction of the rotation axis of the winding bobbin, and is provided on a side surface of the filament. It is characterized in that it is actuated by pressure and is movable according to the winding amount of the filamentous body.

[0017]

[Operation] When the linear body is guided by the guide roller that reciprocates in the direction of the rotation axis and is wound on the bobbin,
The linear body pressing member acts on the linear body in a direction to bring the linear bodies into close contact with the side surface thereof, so that the linear body wound around the bobbin is aligned without any gap.

Since the linear member pressing member has a spherical shape having a diameter larger than the diameter of the linear member, when the linear member is wound in the entire winding width range of the winding bobbin, The linear member pressing member is pushed between the linear member and the end surface of the winding bobbin, moves to the outside of the winding bobbin, and automatically presses the linear member at the next winding stage. Therefore, the filament can be continuously wound.

Further, by making the linear member pressing member rotatable about the rotary damper or movable with respect to the linear guide, the apparatus can be simplified and the cost can be reduced.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a schematic plan view showing a winding device for a filamentous body according to an embodiment of the present invention, FIG. 2 is a schematic front view of the winding device, and FIG. 3 is a detailed view showing a winding state of an optical fiber. FIG. 4 shows a schematic front view of a winding device in which an optical fiber is wound.

As shown in FIGS. 1 and 2, in the optical fiber winding device of this embodiment, the bobbin 11 is a cylindrical barrel 1.
2 and flanges 13 and 14 integrally formed at both ends thereof, and can be rotatably driven by a drive motor (not shown) drivingly connected to the rotary shaft 15. A rotatable guide roller 16 that guides the optical fiber 51 to the bobbin 11 is provided around the bobbin 11.
The optical fiber 51 is reciprocally movable within the range L in which the optical fiber 51 is wound around the barrel 12 of the bobbin 11 along the direction of the rotation axis 15. Therefore, the optical fiber 51 is connected to the rotating shaft 15 of the bobbin 11.
The bobbin 11 is guided by a guide roller 16 which moves along the direction, and can be wound in line with the barrel 12 of the bobbin 11.

On the outer periphery of the bobbin 11, there is provided a pressing member 21 which acts so as to bring the side surfaces of the optical fiber 51 already wound around the bobbin 11 into close contact with each other. That is, a rotary damper 24, which is located on the opposite side of the guide roller 16 on the outer periphery of the bobbin 11, and includes a support base 22 and a rotary base 23 rotatably supported by the support base 22 with a predetermined resistance force. It is provided. The base end of the optical fiber pressing arm 25 is attached to the rotary table 23 of the rotary damper 24 so as to be vertically rotatable by a shaft 26 which is parallel to the rotary shaft 15 of the bobbin 11. A spherical portion 27 is fixed to the tip of the. The diameter D of the spherical portion 27 of the pressing arm 25 is set larger than the diameter d of the optical fiber 51.

Here, the principle of winding the optical fiber 51 on the bobbin 11 in an aligned state without a gap by the winding device of this embodiment will be described. The guide roller 16 that guides the optical fiber 51 is located on one side in the rotation axis direction of the bobbin 11, that is, on the flange 13 side within the range L, and the transport direction of the optical fiber 51 guided by the guide roller 16 is the bobbin 11. It is designed to be orthogonal to the rotation axis direction. From this state, the end portion of the optical fiber 51 sent from the guide roller 16 is locked to the flange 13 of the bobbin 11, the bobbin 11 is rotated by the drive motor, and the guide roller 16 is moved. The guide roller 16 is set to move by the diameter d of the optical fiber 51 for one rotation of the bobbin 11.

At this time, as shown in FIG. 3 (a), since the spherical portion 27 of the pressing arm 25 is pressed against the side surface of the optical fiber 51 with a predetermined pressure, the light wound on the bobbin 11 is taken up. Even if a gap is formed between the fibers 51, the pressing force causes the adjacent optical fibers 51 to be closely wound and wound.

Then, the optical fiber 51 is 1 of the bobbin 11.
When the winding is completed over the entire winding range L of the stage, as shown in FIG.
As shown in (b), the spherical portion 27 of the pressing arm 25 is pushed between the optical fiber 51 and the end surface of the flange 14 of the bobbin 11 and moves to the outside of the bobbin 11. Therefore, even if the optical fiber 51 begins to be wound on the second stage of the bobbin 11,
As in the case of the first stage, the spherical portion 27 is pressed against the side surface of the optical fiber 51, and the optical fiber 51 is wound around the bobbin 11 in a close contact state with no gap. By repeating this process, the optical fiber 51 is wound in close contact with all the steps without any gap, as shown in FIG.

FIG. 5 is a schematic plan view showing a winding device for a filamentous body according to another embodiment of the present invention, and FIG. 6 is a schematic front view of the winding device. The members having the same functions as those in the above-described embodiment are designated by the same reference numerals, and the duplicated description will be omitted.

In the winding device of this embodiment, as shown in FIGS. 5 and 6, the pressing member 31 of the optical fiber 51 provided on the outer periphery of the bobbin 11 is the rotating shaft 15 of the bobbin 11.
It is movable along the direction. That is, bobbin 11
A guide rail 32, which is located on the opposite side of the guide roller 16 and extends along the direction of the rotation axis 15 of the bobbin 11, is provided on the outer periphery of the linear guide 33.
Is movably supported. The linear guide 33 is provided with a base end portion of the optical fiber pressing arm 35 on a shaft 36.
It is attached rotatably up and down by means of a ball-shaped portion 37, which is fixed to the tip of the pressing arm 35.

In the range L, the optical fiber 51 is located on one side of the bobbin 11 in the rotational axis direction, that is, the flange 13.
It is guided by the guide roller 16 that moves from the side to the 14 side, and is wound around the bobbin 11 that is rotated by the drive motor. At this time, since the spherical portion 37 of the pressing arm 35 is pressed against the side surface of the optical fiber 51 with a predetermined pressure, even if there is a gap between the optical fibers 51 wound on the bobbin 11, this Due to the pressing force, the adjacent optical fibers 51 are closely wound and wound up. When the optical fiber 51 is completely wound over the entire winding range L of the first stage of the bobbin 11, the spherical portion 37 of the pressing arm 35 is pushed between the optical fiber 51 and the end surface of the flange 14 of the bobbin 11 to cause the bobbin to move. Move out of 11. Therefore, even if the optical fiber 51 starts to be wound in the second stage of the bobbin 11, the optical fiber 51 is wound in the same manner as in the first stage.
The spherical portion 37 is pressed against the side surface of the optical fiber, and the optical fiber 51 is wound around the bobbin 11 in a state in which the optical fiber 51 is in close contact without a gap.

In the above embodiment, the case where the optical fiber is wound on the bobbin from its end has been described, but it is applicable to other winding methods. FIG. 7 is a perspective view showing a state where one optical fiber is wound around two supplies, and FIG. 8 shows a principle showing a winding method of an optical fiber wound around two supplies.

When the optical fiber for the sensor is wound, one optical fiber is alternately wound in two stages (or one stage) in order to suppress the influence of the change in the value due to the temperature. As shown in FIG. 7, the sensor optical fiber 51
Are wound by the two supply bobbins 61, 62 from the respective ends at the same amount. From the middle part of the sensor optical fiber 51 wound by the two supply bobbins 61, 62, as shown in FIG.
It is wound up in 3 alternately.

One supply bobbin 61 (see FIG. 7) on which the optical fiber 51a is wound is a flange 13 of the bobbin 11.
8A, the bobbin 11 is rotated by the drive motor and the guide roller 16 is rotated as shown in FIG.
By moving the optical fiber 51 to the bobbin 11.
Take up a. At this time, the delivery of the optical fiber 51b from the other supply bobbin 62 is stopped.

Then, as shown in FIG. 8B, when the optical fiber 51a is wound around the bobbin 11 in two stages, the supply of the optical fiber 51a from the supply bobbin 61 is stopped, and the optical fiber 51b is now turned off. The wound supply bobbin 62 is located on the side of the flange 13 of the bobbin 11, and as shown in FIG. 8C, the drive motor rotates the bobbin 11 in the opposite direction to the above and moves the guide roller 16. Then, the optical fiber 51b is wound around the bobbin 11. Then, as shown in FIG. 8D, when the optical fiber 51b is wound around the bobbin 11 in two stages, the supply bobbin 62 (see FIG. 7).
The feeding of the optical fiber 51b from the optical fiber is stopped, and the optical fiber 51a is fed again from the supply bobbin 61 and wound up. In this way, all the optical fibers 51 are wound on the bobbin 11.

Even when the optical fiber for such a sensor is wound, the above-described winding device of the present embodiment can be applied, and the same operational effect can be obtained.

[0035]

As described above in detail with reference to the embodiments, according to the filament winding device of the present invention, the winding bobbin can be wound within the winding width of the winding bobbin. The guide rollers of the filaments located on the outer periphery are configured to guide the filaments to the outer circumference of the winding bobbin while reciprocating in the direction of the rotation axis thereof and wind the filaments on the outer circumference of the bobbin. Since the linear body pressing member that acts in the direction of closely contacting the side faces of the already wound linear body is provided, the linear body pressing member is guided when the linear body is guided by the guide roller and wound on the bobbin. The member acts on the side surface of the filamentous body in the direction in which the filamentous bodies are brought into close contact with each other, and the filamentous body can be wound around the outer periphery of the bobbin in the aligned state without any gaps. The structure can be simplified and the cost can be reduced.

Further, the linear body pressing member is formed into a spherical shape having a diameter larger than the diameter of the linear body, and the linear body is pressed to the linear body by being wound in the entire winding width range of the winding bobbin.
