DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-speed continuous winding device for a filament such as an optical fiber and a method for continuously winding a filament.

[0002]

2. Description of the Related Art When a continuously wound optical fiber or the like is wound around a winding bobbin, a new winding is performed when the winding bobbin is fully wound (a predetermined winding amount). It needs to be replaced with a bobbin and wound up. The sent striatum,
In the case of continuous production, when the winding bobbin is replaced, it is not possible to stop the feeding of the filament and replace the winding bobbin, so the filament is continuously fed. It is necessary to replace the winding bobbin in the state.

The high-speed continuous winding device described in Japanese Patent Application Laid-Open No. Hei 4-246068 is capable of replacing a winding bobbin in a state where a filament is continuously fed.
The high-speed continuous winding device described in Japanese Patent Application Laid-Open No. 4-246068 will be described with reference to FIGS.

In each of the drawings, FIG. 1A is a plan view, and FIG.
The figure is a side view in which the front frame is omitted. In the figure,
1 is a striated body such as an optical fiber, 2a and 2b are winding bobbins,
3 is a guide roller, 4a and 4b are line guides, 5
a and 5b are ratchet wheels, 6 is an upper take-up roller, 7 is a lower take-up roller, and 8a and 8b are suction nozzles. Claw wheel 5a,
5b is provided with a capturing portion for the striatum.

[0005] Take-up rollers 6 and 7 are arranged between the take-up bobbins 2a and 2b, and a line guide 4 that opens and closes on both sides thereof.
a and 4b, and suction nozzles 8a and 8b are arranged below the nozzles. The line shifting guides 4a and 4b each include a pair of rod-shaped rollers, and are configured to be able to open and close. It is normally open.

In this high-speed continuous winding device, the lower take-up roller 7 is driven at a fixed position and is a driving roller. The upper take-up roller 6 is configured as an idle roller, is a driven roller, and is disposed so as to be able to move back and forth and up and down. Normally, the upper take-up roller 6
Is waiting at the ascending and retracting position, but comes into contact with the lower take-up roller 7 by descending from the advanced position, and rotates at the same speed as the lower take-up roller 7. At this time, if the striatum 1 is sandwiched between the upper take-up roller 6 and the lower take-up roller 7, the striatum 1 can be taken.

The suction nozzles 8a and 8b can suck the striated body 1 fed from the upper and lower take-off rollers 6,7. The suction nozzles 8a and 8b are attached to appropriate supporting means so as to be able to move up and down, respectively, but usually stand by at a lowered position. The switching operation of the high-speed continuous winding device will be described.

FIG. 8 shows a normal winding state. In this figure, the striated body 1 is wound around a winding bobbin 2b. The winding bobbin 2a has stopped rotating. The upper take-up roller 6 waits at the raised and retracted position, and the lower take-up roller 7 is not rotating. The suction nozzles 8a and 8b are at the lowered position.

When the winding bobbin 2b reaches a predetermined winding amount,
Switching to the winding bobbin 2a is performed. In the preliminary stage of switching, as shown in FIG. 9, the empty winding bobbin 2a
Then, the lower take-off roller 7 starts idling. In this case, each peripheral speed is made to correspond to the linear speed of the striatum 1. Next, the guide roller 3 moves to the switching position on the winding bobbin 2a side. The line pulling guide 4a on the winding bobbin 2a side closes, and the upper take-up roller 6 advances to above the lower take-up roller 7.

Next, as shown in FIG. 10, a suction start stage is started. At this stage, the take-up bobbin 2a moves forward to a position immediately before the ratchet wheel 5a comes into contact with the striated body 1. Next, the suction nozzle 8b on the side of the winding bobbin 2b starts suction and rises at the same time. Next, the upper take-up roller 6 descends, approaches the lower take-up roller 7 and, at the same time, takes up the striatum 1.

FIG. 11 shows the switching stage. When the rotation of the take-up bobbin 2b stops suddenly, the striated body 1 fed from the take-up rollers 6, 7 is sucked into the suction nozzle 8b. On the other hand, on the winding bobbin 2a side, the catching portion of the ratchet wheel 5a is pushed out, catches the striatum 1 and cuts it. At this time, the end of the striated body 1 is sucked into the suction nozzle 8b via the take-up rollers 6, 7.

When the winding of the filament 1 onto the winding bobbin 2a is started, as shown in FIG. 12, the winding bobbin 2a is retracted to the original position, and the guide roller 3 is moved to the winding bobbin 2a. Move to the normal position for winding. On the other hand, the upper take-up roller 6, the line guide 4a, and the suction nozzle 8b return to their original standby states. Thus, the switching from the winding bobbin 2b to the winding bobbin 2a is completed.

When the winding bobbin 2a is full, the winding bobbin 2b is switched to an empty bobbin.
In this case, the guide roller 3 is moved to the position shown in FIG. 13, the take-up rollers 6, 7 take the striatum 1, the take-up bobbin 2b moves forward, the catching portion of the ratchet wheel 2b is pushed out, and The strip 1 is caught and cut. The fed linear body 1 is sucked into the suction nozzle 8a.

In this manner, the bobbin on the full winding side is stopped so that the bobbin can be taken off by the take-off roller at the time of switching, and the striated body until the completion of the switching is sucked into the suction nozzle. By switching, the end of the striated body after switching is also sucked into the suction nozzle, so that the end of the cut striated body does not hit the striated body wound on the full bobbin, and the wound wire It does not injure the striatum. Therefore, it is effective to apply the present invention to a high-speed continuous winding device such as an optical fiber in which the damage due to external damage may greatly affect the deterioration of the characteristics.

[0015] However, this high-speed continuous winding device
When the linear velocity increases and exceeds about 1000 m / min, the take-off roller does not operate normally, and squeezing occurs. This is because when the linear body 1 is sandwiched between the lower take-up roller 7 configured as a drive roller and the upper take-up roller 6 configured as a driven roller, the lower take-up roller 7 While being rotated at a speed substantially equal to the linear speed of the body 1, the upper take-up roller 6
However, even when the driven rotation is started, the peripheral speed cannot immediately reach the predetermined peripheral speed, and a difference in the peripheral speed occurs between the two rollers. Due to this peripheral speed difference, the filament 1 may be severely squeezed at a high speed, and may be broken when the filament 1 is an optical fiber.

Further, before the winding bobbin 2b stops,
The ends of the striatum 1 are the take-up rollers 6, 7 and the suction nozzle 8b
When it comes out of the winding bobbin 2b, it strikes the wire and damages the wound striated body.

The fact that there are two upper take-up rollers 6 constituted as driven rollers makes the filament 1 easier to squeeze and also makes the direction of exit from the take-up rollers 6, 7 unstable. I have. If the outgoing line direction is unstable, suction by the suction nozzle 8b may fail,
The slack line is caught somewhere and is broken, and the terminal strikes the winding bobbin 2b.

In addition, the fact that the suction ports of the suction nozzles 8a and 8b are widened in conformity with the shape of the bobbin cannot increase the average suction wind speed, so that the terminal cannot be sucked at a high speed, and a slack line is formed. The terminal is caught somewhere and disconnected, and the terminal strikes the wire on the winding bobbin 2b.

On the other hand, in Japanese Patent Application Laid-Open No. 7-69530, a pressing roller 44 is provided between two winding bobbins.
44 'are arranged and accumulators 46 and 46' are used. The holding rollers 44, 44 'and the accumulators 46, 46' are not intended to prevent the terminal from hitting the winding bobbin 12 and prevent the terminal cover from rotating until the rotation of the spooler 10 is stopped. 24 is adopted as a measure against line hitting.

This method is to reduce the impact of wire tapping, and as long as the terminal is near the winding bobbin, wire tapping is inevitable. In particular, it is considered to be insufficient as a countermeasure against line hitting at a high speed of 1000 m / min.

The accumulators 46 and 46 'are
In addition to the problem of not being able to absorb the striated body as long as the suction nozzle, there is also a problem that it cannot cope with the speed at which the winding bobbin stops suddenly. Inserting the striatum between the pinch rollers which are closed from the beginning, like the pressing rollers 44 and 44 ', is particularly unstable at high speeds. In order to be
When applied to the high-speed continuous winding device described in Japanese Patent Application Laid-Open No. 246068/1992, the winding bobbin 2b is braked before being inserted into the winding bobbin 2b. The probability increases. The purpose of the relative rotation of the pressing rollers 44 and 44 ′ is to form a pass line of the striated body after the striated body is gripped, and does not contribute to prevention of striking.

In the continuous winding device described in Japanese Patent Application Laid-Open No. 9-142867, a take-up roller is arranged between two winding bobbins. It is disclosed that both upper and lower take-up rollers may be provided with a drive mechanism.

However, this continuous winding device does not take into account wire striking or ironing. The ironing at high speed is not different from the high-speed continuous winding device described in JP-A-4-246068. Further, when both the upper and lower take-up rollers are driven, a problem arises in that a slip is constantly generated and the optical fiber and the drive system of the rollers are damaged. This take-off roller is provided to cut off the tension from the full bobbin to the empty bobbin, has no consideration for hitting the wire, and has no effect in preventing the hitting of the wire.

As described above, in the conventional high-speed continuous winding device, at higher speeds, there is an unavoidable problem that the breaking of the optical fiber due to the squeezing of the optical fiber and the hitting of the bobbin on the full winding side may occur.

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 6 are schematic structural views for explaining an embodiment of a high-speed continuous winding device for a filament according to the present invention, together with its operation. In each of the drawings, (A) is a plan view, and (B) is a side view in which a front frame is omitted. In FIG. (A), a cross section of the ratchet is illustrated.

In the figure, reference numeral 1 denotes a striatum such as an optical fiber, 2a,
2b is a take-up bobbin, 3 is a guide roller, 4a and 4b are line guides, 5a and 5b are ratchet wheels, 6 is an upper take-up roller, 7 is a lower take-up roller, 8a and 8b are suction nozzles,
9a and 9b are cutters. Each of the ratchet wheels 5a and 5b is provided with a capturing part for the striatum.

The take-up rollers 6 and 7 are arranged between the take-up bobbins 2a and 2b, and line guides 4a and 4
b, suction nozzle 8 with its mouth directed downward and upward
a and 8b are arranged. Line guides 4a, 4b
Are rod-shaped rollers, and are supported on a base (not shown) so as to be separately movable.

In the case of this embodiment, the lower take-up roller 7 is configured as a drive roller driven by itself, and is provided movably in the front-rear direction. On the other hand, the upper take-up roller 6 is basically one idle roller and is supported by a bearing. Therefore, when the upper take-up roller 6 comes into contact with the lower take-up roller 7 which is a driving roller, the lower take-up roller 7 is driven to rotate. Can rotate. In this embodiment, a support shaft that supports the upper take-up roller 6 via a bearing is drivable, and can be rotated by being connected to a power source. When the support shaft is driven to rotate, the upper take-up roller 6 can rotate and rotate with the rotation of the support shaft via the frictional resistance of the bearing. However, since the support shaft and the upper take-up roller 6 rotate with a certain amount of power transmission via viscous resistance or frictional resistance and reduce the rotational resistance, the driving torque of the upper take-up roller 6 is small, and When it comes into contact with the body 1, it is driven to rotate. Further, the upper take-up roller 6
It can move up and down, left and right, and back and forth, and usually stands by at a raised and retracted position. Basically, the left and right positions may be on standby. At the time of switching, the upper take-up roller 6 advances together with the lower take-up roller 7, further moves to a position on the take-up bobbin side that is currently being taken up, and then descends to approach the lower take-up roller 7. Pickup roller 7
It rotates at the same speed as. At this time, the filament 1 is sandwiched between the upper take-up roller 6 and the lower
Can be picked up.

The suction nozzles 8a and 8b can suck the filament 1 drawn out from between the upper take-up roller 6 and the lower take-up roller 7. At this time, the position of the upper take-up roller 6 is not directly above the lower take-up roller 7, but is a position shifted downward in a direction closer to the bobbin being wound and comes into contact therewith. This is because, when the linear member 1 is in contact with a direction directly above the lower take-off roller or in a direction close to the stopped bobbin, the drawn linear body 1 is fed to a position distant from the suction nozzles 8a and 8b and cannot be sucked. Suction nozzles 8a, 8
b are mounted on suitable support means so that they can move up and down, respectively, and are usually waiting at the lowered position.

The switching operation of the high-speed continuous winding device according to this embodiment will be described.

FIG. 1 shows a normal winding state. In the winding state, the filament 1 is wound on the winding bobbin 2b. The take-up bobbin 2a has stopped rotating. The upper take-up roller 6 is at the ascending / retracting position and stands by on the winding bobbin 2a side. The lower take-off roller 7 is also at the retracted position,
Not rotating. The suction nozzles 8a and 8b are at the lowered position.

When the winding bobbin 2b reaches a predetermined winding amount,
Switching to the winding bobbin 2a is performed. In the preliminary stage of switching, as shown in FIG. 2, the empty winding bobbin 2a
Then, the support shafts of the lower take-up roller 7 and the upper take-up roller 6 start rotating. In this case, each peripheral speed is the linear body 1
To the linear velocity of In this state, the guide roller 3 moves to the switching position on the winding bobbin 2a side. The line guide 4a on the winding bobbin 2a advances. The upper take-up roller 6 moves to the take-up bobbin 2b side, and the lower take-up roller 7
Advance with.

Next, as shown in FIG. 3, the suction start stage is started. At this stage, the winding bobbin 2a moves forward and the ratchet wheel 5
a is the position immediately before contact with the striatum 1. Next, the suction nozzle 8b on the side of the winding bobbin 2b starts suction and rises at the same time. At the same time as the upper take-up roller 6 descends and comes into contact with the lower take-up roller 7, the striatum 1 is taken up.

FIG. 4 shows the switching stage. At the same time that the filament 1 is taken up by the upper take-up roller 6 and the lower take-up roller 7, the rotation of the winding bobbin 2b is suddenly stopped, and the filament 1 taken out from the take-up rollers 6, 7 is drawn by the suction nozzle 8b. Sucked into. At this time, the suction port of the suction nozzle has moved to the wire exit position of the striatum near the position where the striatum is gripped by the take-up rollers 6, 7. It is preferable that the suction port has a shape facing only the striatum. The upper take-up roller 6 and the lower take-up roller 7 retreat while feeding out the striatum 1. The striatum 1 is caught by the catching portion of the ratchet wheel 5a and cut by the cutter 9a. The end of the filament 1 is sucked into the suction nozzle 8b via the upper and lower take-off rollers 6,7.

When the winding of the filament 1 onto the winding bobbin 2a is started, as shown in FIG. 5, the winding bobbin 2a is retracted to the original position, and the guide roller 3 is moved to the winding bobbin 2a. Move to the normal position for winding. On the other hand, the upper take-up roller 6, the line guide 4a, and the suction nozzle 8b return to their original standby states. Thus, the switching from the winding bobbin 2b to the winding bobbin 2a is completed.

When the winding bobbin 2a is full, the winding bobbin 2b is switched to an empty bobbin.
In this case, the guide roller 3 moves to the position shown in FIG. 6, the upper and lower take-up rollers 6, 7 take up the striatum 1, the take-up bobbin 2b moves forward, and the catching portion of the ratchet wheel 2b is It is extruded and catches and cuts the striatum 1. The fed linear body 1 is sucked into the suction nozzle 8a.

In this embodiment, the upper take-up roller 6
When the linear body 1 is taken up by the lower take-up roller 7 and the peripheral speed of the upper take-up roller 6 is also rotated at a speed substantially equal to the linear speed of the striated body 1, even at a high speed,
The striated body 1 is not severely wrinkled, and there is no danger of disconnection even when the striated body 1 is an optical fiber.

In addition, instead of rotating the support shaft of the upper take-up roller 6 as a driven roller, an air bearing (a gas flows between the support shaft and the roller) is used for the bearing.
Or a low-resistance bearing. By using a low-resistance bearing, the time required for the upper take-up roller 6 to shift to the driven rotation can be shortened even if the upper take-up roller 6 is not rotated in advance, and ironing can be suppressed. The upper take-up roller 6 preferably has a small moment of inertia. At this time, if the rollers are rotated in advance, the rotation transition time can be further reduced.

The cutting as in the conventional example described with reference to FIGS. 8 to 13 may be performed without using a cutter.

In the conventional example described with reference to FIGS. 8 to 13, two upper take-up rollers 6 are arranged. However, if there are two driven rollers, ironing is likely to occur. Therefore, as described above, measures were taken to suppress ironing, but one upper take-up roller 6 is better. With reference to FIG. 7, a description will be given of a take-off operation in the case where the number of driven rollers is one.
7, the same parts as those in FIGS. 1 to 6 are denoted by the same reference numerals, and the description will be omitted. 1a, 1b, and 1c all indicate the position of the striatum. 1a is the winding start position, 1b
Is a full winding position, and 1c is a position in the outgoing line direction.

As shown in FIG. 7 (B), when the upper take-up roller 6 comes into contact with the lower take-up roller 7 from directly above, the striatum takes the direction of 1c and a position distant from the suction nozzle 8b. Can not be sucked out. When the lower take-up roller 7 comes into contact with a direction close to the take-up bobbin being stopped, the direction is further away from the suction nozzle 8b. If the suction fails, the terminal will strike.

As shown in FIG. 7A, when the position where the upper take-up roller 6 comes into contact with the lower take-up roller 7 comes into contact with a direction closer to the winding bobbin 2b on the full winding side, the suction nozzle 8b
The striatum can be drawn out in the vicinity of the suction port, thereby preventing the suction from failing.

As shown in FIG. 6, the winding bobbin 2 on the full winding side
When switching from a to the empty take-up bobbin 2b, the upper take-up roller 6 is brought into contact in a direction closer to the take-up bobbin 2a than directly above the lower take-up roller 7. Therefore, when there is one upper take-up roller 6, the position where the upper take-up roller 6 is in contact with the lower take-up roller 7 should be relatively moved in accordance with the switching direction of the winding bobbin. Good.

[0054]

As is apparent from the above description, according to the first to ninth aspects of the present invention, in the high-speed continuous winding device for the filament, the ironing is prevented when the winding roller is switched. In particular, even at a high speed of 1000 m / min, the striatum can be prevented from being cut, and the striated body can be prevented from being hit at the end of the striatum at the time of disconnection.

Further, according to the present invention, it is possible to prevent failure of suction by the suction nozzle, and to prevent the terminal from hitting the line when the suction fails.
