Description

The present disclosure relates to a winding method for a filament made of intermittent tape cores.

In the process of manufacturing the filamentary body, the manufactured filamentous body is wound on a bobbin. When the filamentous body is wound around the bobbin, it is generally wound while aligning the filamentous body. Disordered winding causes damage to the filamentous body by twisting or entangling it when the filamentous body is paid out. Traditionally, a traverse device has been used to align and wind filaments onto bobbins. The traverse device reciprocates the filamentary body between the flanges at both ends of the bobbin by moving the filamentous body in a direction orthogonal to the running direction (hereinafter referred to as "traverse") when winding the filamentary body around the bobbin. It is a device that winds up while

When winding the filament while traversing it, it is necessary to reverse the traverse direction (hereinafter referred to as "traverse turn") when the filament is wound up to the collar of the bobbin, for example. Even though the traverse speed is kept constant, uniform winding can be achieved, but the traverse speed needs to be decelerated and accelerated during traverse turns, so the winding state of the filament tends to be disturbed near the bobbin collar.

Patent Literature 1 proposes a method of suppressing disturbance in the winding state of the filament body near the collar of the bobbin during the traverse turn by shortening the time required for the traverse turn. In Patent Document 1, as shown in FIG. 7, a traverse device 50 comprising a ball screw 54 and a servomotor 55 is provided on the side of a guide 53 for feeding a filament 51 to a bobbin 52, and a ball screw 64 is provided on the bobbin 52 side. and a servomotor 65, and by simultaneously moving both traverse devices 50, 60 during a traverse turn, the time required for the traverse turn is shortened.

JP 2005-145626

However, the technique described in Patent Document 1 requires traverse devices on both the guide side and the bobbin side. Also, for example, when traversing a filamentary body in which intermittent tape core wires or optical fiber core wires with a smaller diameter than usual are connected with a width, the rigidity of the filamentary body is small, so the speed change during traversing turns is small. If it is too large, the alignment of the optical fibers of the intermittent optical fiber ribbon may be disrupted on the guide side, resulting in disturbance of the winding state of the filament near the collar of the bobbin.

SUMMARY OF THE INVENTION It is an object of the present invention to suppress the disturbance of the winding state of a filament in the vicinity of the collar of the bobbin due to the traverse turn, by means of a traverse device of a simple configuration, even when the intermittent fiber ribbon is wound around the bobbin. To provide a filament winding method capable of

[Description of Embodiments of the Present Disclosure]
First, the contents of the embodiments of the present disclosure will be listed and explained.
The present disclosure has the following effects due to the configurations (1) to (4).
(1) A filament winding method for winding the filament around a bobbin using a traverse device for traversing the filament, wherein the filament is a plurality of optical fibers adjacent to each other. An intermittent tape fiber is composed of a connection region in which the optical fiber core wires are connected to each other and a non-connection region in which the adjacent optical fiber core wires are separated from each other, and the traverse device has a traverse speed command value can be changed, and the traverse speed command value is decreased by a predetermined amount in a predetermined time until the traverse direction is reversed.
According to the filament winding method configured in this manner, even when the intermittent fiber ribbon is wound on the bobbin, the traverse device of a simple configuration can be used to remove the wire in the vicinity of the collar of the bobbin accompanying the traverse turn. Disturbance in the winding state of the filament can be suppressed. In particular, in the case of a filament such as an intermittent fiber ribbon, the filament has a low rigidity, and is therefore likely to be wound turbulently during a traverse turn. In the conventional technology, when the speed change during the traverse turn is large, the speed change during the traverse turn becomes large on the guide side. As a result, the intermittent tape fiber on the final guide roller side cannot follow the movement associated with the bobbin turn, and is pushed by the guide roller collar. There is a possibility that the winding state of the filament may be disturbed. According to the above configuration, by decreasing the traverse speed command value by a predetermined amount at a predetermined time corresponding to the traverse turn, the time required for the traverse turn of the intermittent ribbon core can be lengthened. By decreasing the traverse speed command value by a predetermined amount, the traverse speed can be reduced by a predetermined amount. Since the intermittent tape fiber can follow the movement accompanying the traverse turn on the final guide roller side, it is suppressed from being pushed by the guide roller collar. As a result, the lateral pressure received from the guide roller collar is also greatly relieved, so that it is possible to prevent the alignment of the optical fibers from collapsing on the final guide roller side.

(2) In the wire winding method described above, when the predetermined time until the traverse direction is reversed is t [ms] and the bobbin rotation speed is N [rpm],
40 [ms] ≤ t ≤ 60 × 1000/N [ms]
0<N≦1500 [rpm]
satisfy the relationship
As a result, it is possible to prevent the alignment of the optical fibers of the intermittent optical fiber ribbon from being disturbed on the final guide roller side, and to prevent the filament winding from being disturbed in the vicinity of the collar of the bobbin. The conditions for doing so become clear. Generally, the sequencer scan time is about 40ms, so
40ms≤t
If so, the traverse speed can be reduced before the actual turn. As a result, pushing by the guide roller flange during traverse turn is suppressed, and as a result, the lateral pressure received from the guide roller flange is greatly reduced, thereby suppressing deterioration of alignment of the optical fibers. be able to. Also, if the speed is reduced too quickly, the length of time that the striatum overlaps and is wound becomes longer.
t≦60×1000/N [ms]
0<N≦1500 [rpm]
As a result, the traverse speed is decelerated only for one rotation of the bobbin, so that the influence of overlapping winding of the filaments can be reduced, and entanglement and twisting of the respective optical fibers can be suppressed.

(3) In the method for winding a filamentary body, the diameter of each of the optical fibers constituting the intermittent ribbon is 200 μm or less.
As a result, in the prior art, when intermittent tape core wires or optical fiber core wires with a small diameter are connected, the filaments are likely to be entangled or twisted in the vicinity of the collar of the bobbin due to the traverse turn. By the way, according to the above configuration, even if the optical fiber is an intermittent ribbon and the diameter of each optical fiber is 200 μm or less, the entanglement and twisting of the filaments in the vicinity of the collar of the bobbin caused by the traverse turn can be prevented. can be suppressed.

(4) In the method for winding a filamentous body, a predetermined gap is provided between the filamentary body wound on the bobbin and the collar portion of the bobbin.
As a result, the filament can be prevented from being disturbed by interfering with the bobbin collar, and entanglement and twisting of the filament in the vicinity of the bobbin collar due to traverse turn can be suppressed.

[Details of the embodiment of the present disclosure]
A specific example of the filamentary body winding method according to the present disclosure will be described below.
In the following description, configurations denoted by the same reference numerals in different drawings may be the same, and descriptions thereof may be omitted.
In addition, the present disclosure is not limited to these examples, but is indicated by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.

[Regarding the intermittent fiber ribbon]
FIG. 1 is a schematic diagram of the intermittent fiber ribbon 10, showing a state in which the intermittent fiber ribbon 10 is opened in the arrangement direction. The intermittent tape core wire 10 includes, for example, a connection region 12 in which adjacent portions of the plurality of optical fiber core wires 11 are connected, and a non-connection region 13 in which the adjacent portions of the optical fiber core wires 11 are separated from each other. It consists of A tape coating made of, for example, a high-hardness resin is provided around each optical fiber core wire 11. Adjacent tape coatings are continuous in the connection region 12, and adjacent tape coatings are in the non-connection region 13. are separated without being connected.

In general, the smaller the diameter of each optical fiber core wire 11 is, the more likely it is to be entangled or twisted during winding on the bobbin 20. However, in this embodiment, each optical fiber core wire Even if the diameter of the intermittent fiber ribbon 11 is as small as 200 μm or less, tangling and twisting of the intermittent fiber ribbon 10 can be suppressed.

FIG. 2A is an explanatory diagram of the winding of the intermittent fiber ribbon 10 from the final guide roller 30 to the bobbin 20. FIG. FIG. 2B is a front view of the bobbin 20 of FIG. 2A. The bobbin 20 has a cylindrical body 21 and flanges 22 at both ends of the body 21 . The bobbin 20 is rotationally driven at a rotational speed N [rpm] by a bobbin rotation drive device (not shown), and traverses so as to reciprocate in the axial direction of the body 21 by a traverse device (not shown). Since the bobbin 20 is traversed by the traverse device and driven to rotate by the bobbin rotation drive device, the intermittent fiber ribbon 10 guided by the final guide rollers 30 is held constant between the flanges 22 at both ends of the body 21. is wound at a pitch of As a result, the wound intermittent fiber ribbon 10 is wound in an aligned manner.

The final guide roller 30 is rotatably attached to the tip of the guide roller fixing piece 26 . The guide roller fixed piece 26 is supported by the support piece 24 via the connecting member 25 . A front stage guide roller 23 is rotatably arranged in front of the final guide roller 30 . The intermittent fiber ribbon 10 is sent out to the body 21 of the bobbin 20 while being properly tensioned through the preceding guide roller 23 and the final guide roller 30 .

The final guide roller 30 is provided closer to the body 21 of the bobbin 20 than the preceding guide roller 23 is. The final guide roller 30 is arranged, for example, on a vertical line of the central axis of the body 21, and the support piece 24 is extended in the longitudinal direction so that the distance from the wound intermittent ribbon core 10 is kept constant. position is adjusted to

FIG. 3A is an enlarged view of region IIIA near the final guide roller 30 in FIG. 2B. The final guide roller 30 is rotatably fixed to a guide roller shaft 31 provided at the tip of the guide roller fixing piece 26 by a guide roller fixing nut 32 . The final guide roller 30 has a cylindrical body 33 and guide roller flanges 34 provided at both ends of the body 33 . The width of the body portion 33 of the final guide roller 30, that is, the distance between the pair of guide roller collar portions 34, is set to be substantially equal to or slightly larger than the width of the intermittent ribbon core 10. As shown in FIG. This is a state in which the optical fibers 11 of the intermittent optical fiber ribbon 10 are aligned in parallel with the arrangement direction, and the trunk portion 33 guides the optical fiber optical fibers 11 of the intermittent optical fiber ribbon 10 without collapsing the aligned state. This is because

The collar-side end 16 of the wound intermittent fiber ribbon 10 is wound at a predetermined distance from the collar 22 of the bobbin 20 . Although this predetermined distance is not particularly limited, it is a distance of 1/2 to several sheets of the width of one sheet of the intermittent optical fiber ribbon 10 in which the respective optical fiber optical fibers 11 are arranged parallel to the arrangement direction. be able to. Thereby, a predetermined space is provided between the flange-side end portion 16 and the flange 22 . An inclined portion 17 is provided at the end of the wound intermittent fiber ribbon 10 on the collar 22 side of the bobbin 20 . That is, the wound intermittent fiber ribbon 10 is wound so that the end portion on the flange 22 side is separated from the flange 22 as it approaches the upper layer.

A gap is provided between the collar-side end 16 of the wound intermittent fiber ribbon 10 and the flange 22 to prevent the intermittent fiber ribbon 10 from interfering with the flange 22 of the bobbin, It is possible to prevent the guide roller fixing piece 26 or the like fixing the final guide roller 30 from coming into contact with the collar 22 of the bobbin 20 .

In addition, since the inclined portion 17 is provided, the ends of the intermittent fiber ribbons 10 of each layer on the flange 22 side are displaced outward from the ends of the intermittent fiber ribbons 10 of the lower layer on the flange 22 side. Since the winding does not collapse, it is possible to suppress entanglement and twisting of the filamentary body in the vicinity of the collar of the bobbin due to the traverse turn.

FIG. 3B is a partially enlarged view of region IIIB near the final guide roller 30 in FIG. 3A. A guide corner portion 35 is formed along the circumference between the body portion 33 of the final guide roller 30 and the guide roller collar portion 34 . It is desirable that the intermittent optical fiber ribbon 10 be guided by the trunk portion 33 without causing the alignment of the optical fibers 11 to be disturbed even at the guide corner 35 and its vicinity. During a traverse turn in which the bobbin 20 switches from straight left to straight right as viewed in the drawing, the traverse speed command value is decreased by a predetermined amount in a predetermined time until the traverse direction is reversed. The time required for a traverse turn can be lengthened. Since the intermittent fiber ribbon 10 can follow the movement accompanying the traverse turn on the final guide roller 30 side, it is suppressed from being pushed by the guide roller flange 34 . As a result, the lateral pressure received from the guide roller flange 34 is greatly relieved, so that the optical fibers 11 are guided by the body 33 on the final guide roller 30 side without losing their aligned state. Here, in FIG. 3A, the traverse direction of the bobbin 20 before the traverse turn is referred to as "straight left" (same applies hereinafter). Similarly, the traverse direction after the traverse turn is called "straight to the right" (hereinafter the same).

FIG. 3C is a partially enlarged view of region IIIC in the vicinity of the final guide roller 30 in FIG. 3A, and is a diagram for explaining a comparative example with respect to the vicinity of the final guide roller 30 in FIG. 3B. It shows how the intermittent ribbon 10 is guided by the final guide roller when the traverse speed command value does not decrease during a traverse turn in which the bobbin 20 switches from left straight to right straight. In the comparative example of FIG. 3C, a rapid speed change occurs in the intermittent ribbon core 10 guided by the final guide roller 30 during the traverse turn. Therefore, the intermittent fiber ribbon 10 cannot follow the movement accompanying the traverse turn on the final guide roller 30 side, and is pushed by the guide roller collar portion 34, increasing the side pressure received from the guide roller collar portion 34. As a result, the alignment of the optical fibers 11 of the intermittent optical fiber ribbon 10 is disturbed, particularly near the corners 35 , and the wound state of the filaments near the collar 22 of the bobbin 20 is disturbed.

In order to prevent the intermittent ribbon 10 guided by the final guide roller 30 from being disturbed during the traverse turn, the traverse speed The command value should be decreased by a predetermined amount.

FIG. 4 is a graph of winding wire speed V _W , traverse speed V _T and bobbin rotation speed N. FIG. In FIG. 4, (A) is a graph of time change of winding linear speed V _W [m/min], (B) is a graph of time change of traverse speed V _T [m/min], and (C) is a graph of time change of traverse speed V T [m/min]. is a graph of time change of bobbin rotation speed N [rpm]. The time axis T(s) of each graph of (A) to (C) correspond to each other.

In FIG. 4A, the winding wire speed _VW linearly increases from 0 to _VW1 from time 0 to time Tb, and becomes a constant winding wire speed _VW1 after time Tb. ing.

In FIG. 4B, the traverse speed _VT is defined to have a positive value when the bobbin 20 is traveling straight left and a negative value when the bobbin 20 is traveling right straight. The traverse speed _{VT increases linearly from 0 to VT01 from} time 0 to time Ta, and at time Ta, the first traverse turn is performed, and the bobbin 20 moves straight left from _VT01 to the right. of _VT02 . As a result, the first layer of the intermittent fiber ribbon 10 is wound around the body 21 of the bobbin 20 .

Here, from time 0 to time Tb, since the winding wire speed is increased linearly, the traverse speed is also increased accordingly.
On the other hand, due to the traverse turn at time Ta, the intermittent fiber ribbon 10 is wound as the second layer, so the winding radius of the second layer bobbin 20 on the body 21 is the radius of the body 21 by one layer. is increased by the addition of the thickness of the intermittent optical fiber ribbon 10 (the diameter of the optical fiber optical fiber). Therefore, it is necessary to adjust the traverse speed for the second layer so that it is lower than the traverse speed for the first layer by the thickness of the intermittent ribbon core 10 for one layer.

The traverse speed _VT rises linearly from _VT02 to _VT1 from time Ta to time Tb, and remains constant at traverse speed _VT1 from time Tb to time Tc. At time Tc, the second traverse turn is performed, and the bobbin 20 changes from right straight _VT1 to left straight _VT2 . Between the time Ta and the time Tc, the intermittent core wire 10 of the second layer is wound around the body 21 of the bobbin 20 .

Here, the relationship between _VT1 and _VT2 is
|V _T1 |>|V _T2 |
becomes. Considering that the _thickness of the intermittent fiber ribbon 10 for one layer is greater than the traverse speed _VT1 for the second layer, the traverse speed | _VT2 for the third layer is This is because | is adjusted to be smaller than |V _T1 |.

The traverse speed VT is constant at the traverse speed _VT2 from time Tc to time _Td , and the intermittent ribbon 10 of the third layer is wound around the body 21 of the bobbin 20 . At time _Td , the traverse speed VT changes from left straight _VT2 to right straight _VT3 .
Here, the relationship between _VT2 and _VT3 is
|V _T2 |>|V _T3 |
becomes. This is because the thickness of the intermittent _ribbon 10 for one layer is greater at the fourth layer traverse speed _VT3 than at the third layer traverse speed _{VT2, so that the traverse speed |V T3 |} |

The traverse speed VT is constant at the traverse speed _VT3 from time _Td to time Te, and the intermittent ribbon 10 of the fourth layer is wound around the body 21 of the bobbin 20 . At time Te, the traverse speed _VT changes from right straight _VT3 to left straight _VT4 .
Here, the relationship between _{VT3 and VT4 is} the same as above,
|V _T3 |>|V _T4 |
becomes.

The traverse speed _VT is constant at the traverse speed _VT4 from the time Te until the winding of the fifth layer of the intermittent fiber ribbon 10 is completed, and then decreases as described above when the traverse turns are performed. .

In FIG. 4(c), the bobbin rotation speed N increases linearly from ₀ to N1 from time ₀ to time Tb, and remains at a constant rotation speed N1 from time Tb to time Tc. becomes constant. When a traverse turn is performed at time Tc, the bobbin rotation speed decreases from _N1 to _N2 . The relationship between the bobbin rotation speeds _N1 and _N2 is
_N1 > _N2
becomes. This is because the thickness of the intermittent fiber ribbon 10 for _one layer is greater at the bobbin rotation speed _N2 for the third layer than at the bobbin rotation speed N1 for the _second layer. This is because it is adjusted to be _less than N1.

Regarding the bobbin rotation speed N, the first traverse turn at the time Ta causes the intermittent tape core 10 of the second layer to be wound on the body 21 of the bobbin 20 on the intermittent tape core 10 wound on the first layer. Since the wire 10 is to be wound, the bobbin rotation speed N is adjusted at time Ta. However, since the adjustment amount of the bobbin rotation speed N at time Ta is small, it is omitted in FIG. 4(c).

The bobbin rotation speed N becomes constant at a constant rotation speed _N2 from time Tc to time Td _, and decreases from the bobbin rotation speed _N2 to N3 when a traverse turn is performed at time Td. The relationship between the bobbin rotation speeds _N2 and N3 is the same as above _,
N2 > _N3
becomes.

The bobbin rotation speed N is constant at a constant rotation speed N3 from time _Td to time Te _, and decreases from the bobbin rotation speed N3 to _N4 when a traverse turn is performed at time Te. The relationship between the bobbin rotation speeds _N3 and _N4 is the same as above,
_N3 > _N4
becomes.

The bobbin rotation speed N is constant at a constant rotation speed _N4 from the time Te until the winding of the intermittent fiber ribbon 10 of the fifth layer is completed, and then decreases as described above when the traverse turn is performed. do.

FIG. 5 is an explanatory diagram of the traverse turn acceleration/deceleration time, and is a drawing for explaining the region V in FIG. FIG. 6 is an enlarged view of the traverse turn acceleration/deceleration time in FIG. 5, and is an enlarged view of region VI in FIG. In FIGS. 4-6, _graphs of traverse speed VT are command values given to the traverse device. Further, since FIG. 4 is a schematic diagram, for example, the traverse speed at the time of traverse turn at time Td is drawn as if it were suddenly changed from _VT2 to _VT3 . If it changes, there is a risk that the intermittent ribbon cord 10 guided by the trunk portion 33 will be disturbed (see FIG. 3C) near the guide corner portion 35 .

Therefore, in the present embodiment, as shown in FIG. 5, the traverse speed command value is decreased by a predetermined amount during a predetermined period of time until the traverse turn at time Td. The traverse speed command value starts decreasing from left straight _VT2 at time _Td1 , reaches zero speed at time Td, and accelerates to right straight _VT3 at time _Td2 . Although not particularly limited, the speed change from traverse speed command values _VT2 to _VT3 in the period from time _Td1 to time _Td2 , that is, the set value td of the time required for acceleration/deceleration during traverse turn is It can be linear. The graph of the change in the _traverse speed command value _VT at the set value _td may be other than linear. It is also possible to set the traverse speed command value to be gentle, or to curve the change in the traverse speed command value.

Since the actual traverse speed has a delay time with respect to the traverse speed command value, the response is delayed from the graph of the traverse speed command value.

The value of the set value td, which is the predetermined time corresponding to the traverse turn at the time Td, is the predetermined time until the traverse turn is t [ms] (here, equivalent to the set value td), and the bobbin rotation speed is When N [rpm]
40 [ms] ≤ t ≤ 60 × 1000/N [ms]
0<N≦1500 [rpm]
is set so as to satisfy the relationship of

Generally, the sequencer scan time is about 40ms, so
40ms≤t
By doing so, the traverse speed can be reduced before the actual turn. As a result, the pushing by the guide roller flange 34 during traverse turn is suppressed, and as a result, the side pressure received from the guide roller flange 34 is greatly relieved, so that the optical fibers 11 are not out of alignment. can be suppressed.

Also, if the speed is reduced too quickly, the length of time that the striatum overlaps and is wound becomes longer.
t≦60×1000/N
0<N≤1500
When the set value td is set so as to prevent the intermittent fiber ribbon 10 from being wound in multiple layers near the collar of the bobbin due to the traverse turn, the core wire 10 is prevented from being wound around the body 21 of the bobbin 20. It is possible to suppress entanglement and twisting of the intermittent tape core wires 10 that have been laid. In addition, since the slanted portion 17 is provided at the collar-side end of the intermittent fiber ribbon 10 that has been wound up, the collar-side end of each layer is more inclined than the collar-side end of the lower layer. 22, it is possible to suppress entanglement and twisting of the filament in the vicinity of the bobbin collar due to the traverse turn. Here, when N=1500 rpm,
t=60×1000/1500=40 ms.

FIG. 6 shows an example of a method for setting the traverse turn acceleration/deceleration time in this embodiment. When the time from time Td1 to Td is _td1 and the time from time Td to _Td2 is _td2 , the set value _td is
td= _td1 + _td2
is represented by the formula
here,
|VT2|>|VT3|
Thus, in FIG. 6, _Td is represented as a time between Td1 and _Td2 and close to _Td2 . For this reason,
t _d1 >t _d2
is set to be

In FIGS. 5 and 6, the traverse turn at time Td has been described as an example. It also applies to all traverse turns, eg, traverse turns at times Ta, Tc, Te, and so on.
