Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for storing a long wire such as a wire such as an optical fiber or a wire such as a film while traveling.

[0002]

2. Description of the Related Art For example, in an operation of winding a long optical fiber, when one winding bobbin is fully wound with an optical fiber and then wound on another winding bobbin, the winding is performed on one winding machine. 2. Description of the Related Art Changing a winding bobbin and winding an optical fiber to two winding machines are performed.

[0003] The long optical fiber is continuously supplied to the winding machine even during the change of the winding bobbin and the winding of the winding machine. For this reason, it is necessary to store the continually supplied striated wire during the change of the winding bobbin or the winding of the winding machine.

[0004] A conventional wire storage device generally includes a plurality of fixed rolls and a plurality of movable rolls, and a striated body to be stored is formed so as to meander between the fixed rolls and the movable rolls. (For example, Japanese Patent Application Laid-Open Nos. 58-6862, 64-75348, 1-197261, and 3-8).
No. 1013). In these wire storage devices, the filament is continuously wound at a high speed, or when the winding bobbin change time is long and the storage amount is large, the number of fixed rolls and movable rolls is increased, The movable distance of the movable roll is increased.

However, in the conventional wire storage device, since the striated body passes while meandering over the fixed roll and the movable roll, the striated body is always in contact with these rolls. Disadvantages. (1) The surface of the striated body is damaged by contact with a large number of rolls, and is not particularly suitable for storage of a striated body having a low surface strength such as an optical fiber or a film. (2) When the striated body is an optical fiber, when the optical fiber is meandered alternately between the rolls of the storage device, a large bending in the opposite direction is applied to the optical fiber alternately. This bending increases transmission loss. (3) When the striatum travels in the wire storage device at a high speed, the striatum receives centrifugal force between the fixed roll and the movable roll, so that the striatum cannot travel at a high speed. (4) Even when the wire storage device is not in the wire storage mode, since the striated body meanders between the fixed roll and the movable roll at the minimum interval, a predetermined amount of the striated body remains in the wire storage device, and Waste occurs.

When the number of fixed rolls and movable rolls increases, the path line on the entrance side of the filament and the path line on the exit side shift, and the filament is twisted to deform the filament. , And work to pass the striated body through the wire storage device (wire hanging work)
However, there was a drawback that the workability was low and the workability was low.

[0007]

SUMMARY OF THE INVENTION One object of the present invention is to prevent the striatum from being scratched, bent, abnormally tensioned at high speed running, the residual wire and the striated twist from occurring. Another object of the present invention is to provide a method for storing long filaments that can be easily hooked.

Another problem to be solved by the present invention is that the wire does not suffer from scratching, bending, abnormal tension during high-speed running, residual wire and twisting of the wire, and wire can be easily hooked. An object of the present invention is to provide a wire storage device for a long filament.

[0009]

A first object of the present invention is to form a plurality of storage rolls facing each other along a running path of a long filament so as to sandwich the running path along the running path. At the time of storing the long filaments, at least one of the storage rolls is displaced so as to cross the running path of the long filaments, and the storage filaments facing the long filaments are displaced. It is an object of the present invention to provide a method for storing a long striated body, wherein the long striated body is stored while meandering between rolls.

[0010] A second object of the present invention is to dispose a plurality of storage rolls facing each other along the traveling path along the traveling path of the long filament so as to sandwich the traveling path,
At the time of non-storage of the long striated body, the long striated body is passed without contact or almost non-contact between the storage wire rolls facing each other. Disclosed is a method for storing a long filament which is displaced across a running path of the filament to meander the long filament between opposed storage rolls and store the wire. It is in.

[0011] In the first and second means for solving the problems of the present invention, when storing a long filament, one of the opposing storage rolls is displaced and then the other storage roll is displaced. The storage rollers may be displaced, or both storage rolls of the opposing storage rolls may be simultaneously displaced.

[0012] A third object of the present invention is to provide a long linear body which is opposed to the long linear body so as to sandwich the running path alternately along the running path when the long linear body is not stored. A plurality of wire storing rolls, and a wire storing roll driving means for displacing at least one of the wire storing rolls at the time of storing the wire so as to traverse the running path of the long filament. An object of the present invention is to provide a wire storage device for a strip.

According to a third aspect of the present invention, there is provided a first roll holder for commonly supporting one of the storage rolls and a second roll holder for commonly supporting the other of the storage rolls. The first and second roll holders are arranged on the opposite side to the side on which the corresponding storage rolls are located with the running path of the elongated filament interposed therebetween, and the storage roll driving means is The roll holder supporting one of the wire storage rolls can be driven to be displaced in the direction of displacement.

[0014] In the third means for solving the problems of the present invention, the storage roll driving means displaces both storage rolls of the opposing storage roll, and the other storage roll is replaced with one storage roll. May be displaced after being displaced, or may be displaced together with one of the storage rolls.

As described above, when a plurality of storage rolls facing each other are arranged alternately along the traveling path along the traveling path of the long linear body so as to sandwich the traveling path, in the non-wire storage mode, Since the striated wire does not meander greatly between the storage wire rolls facing each other, the striated wire is not damaged by the storage wire roll, and therefore, a wire having a weak surface strength such as an optical fiber or a film. Suitable for storage wire. In particular, it is preferable that the striated body is an optical fiber, since no bending is given in the wire storage device and a large transmission loss does not occur in the optical fiber.

In particular, when the striated body passes through the non-contact or almost non-contact without meandering between the opposed storage rolls, no damage or bending of the striated body occurs.
The striated body can pass through the wire storage device while maintaining good characteristics.

Further, since the striated body can pass straight or almost straight without meandering between the storage rolls, the striated body is not subjected to centrifugal force in the storage device. In addition, when the striated body can travel at a high speed and is not in the wire storing mode, the striated body does not remain on the wire storing roll and no waste of material occurs.

Since the plurality of storage rolls are arranged along the traveling path, even if the number of rolls is increased, the path line on the entrance side and the exit line on the striated body are not displaced. Without causing deformation such as twisting in the striatum,
Furthermore, since the operation of passing the striated body through the wire storage roll (wire hanging operation) is easy, the workability can be improved.

The striated body is not in non-contact or almost non-contact, but it can be made to pass between the storage rolls in a non-storing mode in the form of ripples. It is suitable when the surface strength is not so low and no damage is caused even when it comes into contact with the wire storage roll. Also in this case, since the centrifugal force does not act on the striated body, the striated body can be processed at a high speed, and no useless remnant wire is generated in the wire storage device.

The outputs of the position detectors 54 and 68 of the motors 50 and 60 are fed back to the drive circuits of the motors 50 and 60, and
60 is controlled.

Next, using the wire storage method of the present invention, the wire 10
A method of continuously winding A will be described sequentially with reference to FIGS. In the wire storage device 14, the wire storage rolls 22 and 24 are normally opened up and down as shown in FIG.
The wire rod 10A passes between these storage rolls 22 and 24 without contacting the storage rolls 22 and 24, and also passes through the clamp device 16 and the cutter device 18, which are also open, on the winding device 20. Is wound on the winding bobbin 20A.

When the winding bobbin 20A is almost full and a full winding signal is generated, the main activation switch 80 of the control means 78 of the wire storage device 14 is closed. This main start switch 8
0 may be automatically closed based on the full signal, or may be manually closed by an operator by generating an alarm by the full signal.

When the main activation switch 80 is closed, the storage device 14 is activated. As can be seen from FIG.
Is driven, the motor 60 with the speed reducer is driven, and the lower storage roller 24 is raised via the powder clutch 62. On the other hand, the winding device 20 gradually decelerates and finally stops. Thereafter, the clamp device 16 is closed, and the cutter device 18 is operated to cut a subsequent wire from the wire 10A wound on the winding bobbin 20A on the winding device 20. In addition, the cutter device 18 cuts the wire 10A leaving a length necessary for fixing the subsequent wire 10A on the next winding bobbin 20B at the downstream side of the clamp device 16 later.

Thereafter, the take-up device 20 removes the take-up bobbin 20A of the whole number of rolls, and removes the new empty take-up bobbin 2A.
0B is set in the winding device 20. On the other hand, during this time, since the wire storage roll 24 of the wire storage device 14 continuously rises,
Wire 10 clamped by clamping device 16
The wire portion after A is stored in the wire storage device 14.

When the supply speed of the wire rod 10A is high, and the supply amount of the wire rod 10A fed into the wire storage device 14 during the change from the winding bobbin 20A to the winding bobbin 20B is large, the storage roller 24 is being lifted. And the first roll drive mechanism 40
Also starts driving, and the lowering of the first storage roller 24 also starts. By driving both storage rolls 22 and 24 in this manner, it is possible to sufficiently cope with a high supply speed of the wire 10A.

On the other hand, after the take-up device 20 is replaced with a new empty take-up bobbin 20B, the wire portion remaining downstream from the clamp device 16 is fixed to the new take-up bobbin 20B, and the wire storage device 14 To stop mode. In this stop mode, when the main start switch 80 is opened and the stop mode switch (not shown) is closed at the same time, the first
And the second roll driving mechanisms 40 and 42 are reversed in the line-reducing direction in response to the tension signal St.

At the same time when the clamp device 16 is opened, the winding device 20 starts the winding operation. At first, the winding device 20 starts up at a speed faster than the normal operation, and the wire storage device 1
Since the wire 10A inside the wire 4 is pulled, the wire storage device 14 reverses in the line-reducing direction according to the tension of the wire 10A. The reverse rotation of the wire storage device 14 is performed by driving the first and second roll drive mechanisms 42 and 40 such that the wire storage roll 24 first descends and the wire storage roll 22 rises halfway. Since the positions of the first and second storage rolls 22 and 24 are detected by the position detectors 54 and 68, these storage rolls 22 and 24 are set at their upper limits based on the output signals of the position detectors. It is controlled to stop at the position and the lower limit position.

When the wire storage device 14 returns to its original position, the first and second
Are suspended above and below the traveling path PA of the wire 10A from the wire 10A, and at this time, the winding device 20 returns from the start-up operation to the steady operation, and thereafter, this new winding bobbin This steady operation is maintained until 20B is fully wound. It should be noted that during steady operation, the storage device 20
The predetermined tension is maintained by a dancer device (not shown) provided on the upstream side of.

The operation of raising and lowering the storage rolls 24 and 22 of the storage device 20 is performed according to a tension signal St output from the tension meter 12. If the supply speed of the wire 10A is low and the fluctuation of the tension is small, only the wire storage roll 24 is driven. If the supply speed of the wire 10A is high and the fluctuation of the tension is large, as described above, the wire is stored from the middle. The downward drive of the line roll 22 is also performed.

In the above embodiment, the storage wire roll 22,
Of the 24, one storage roller 24 is first raised, and the storage roller 22 is lowered halfway in accordance with the stored dose, but both the storage rolls 22 and 24 may be driven from the beginning, Also, only one of the storage rolls 22 or 24 is driven,
The other wire storage roll 24 or 22 may be kept stationary.

In the above-described embodiment, the upper and lower storage rolls 22 and 24 are sufficiently opened so that the wire 10A can pass through the storage rolls 22 and 24 without contact. Of the wire storing rolls 22 and 24 may be small, and the wire 10A may pass through the wire storing rolls 22 and 24 to a degree close to non-contact such that the wire 10A slightly rubs.
To the extent that the contact is close to non-contact, the wire 10A is
It is to the extent that it is not damaged by 2,24.

In the above-described embodiment, when the wire is not stored, the striated body passes between the opposed wire storage rolls 22 and 24 without or almost without contact. Alternatively, the air may pass between the storage rolls 22 and 24 in the form of ripples. This is suitable in the case where the surface strength of the striated body 10 is not so small, and no damage is caused even when the striated body 10 comes into contact with the storage wire roll. In this case, unlike the prior art, no centrifugal force acts on the striated body, so that the striated body can be processed at a high speed, and no useless residual wire is generated in the wire storage device. .

In the above embodiment, the wire storage roll 2
The storage rolls 2 and 24 are vertically arranged so as to be displaced in the vertical direction when storing.
The reference numerals 2 and 24 may be arranged horizontally horizontally on the left and right so as to be displaced in the horizontal direction at the time of storing a wire. Further, in the above-described embodiment, the case where the long filament 10 is applied to a wire 10A such as an optical fiber has been described, but the present invention can be similarly applied to a filament such as a film.

[0047]

According to the present invention, as described above, a plurality of opposite storage rolls are alternately arranged along the running path along the running path of the long filament so as to sandwich the running path. In the non-storing mode, the long striated body does not meander greatly between the opposed storage rolls, so that the striated body is not damaged by the storage rolls, and therefore, the optical fiber or the film is not used. It is suitable for the storage wire of a striatum having low surface strength. In particular, when the striated body is an optical fiber, it is preferable because a large bending is not applied in the wire storage device and a large transmission loss does not occur in the optical fiber.

In particular, when the striated body passes without contact or almost non-contact without meandering between the opposing storage rolls, no damage or bending of the striated body occurs.
The striated body can pass through the wire storage device while maintaining good characteristics.

Further, since the striated body can pass straight or almost linearly without meandering between the storage rolls, even when the striated body passes at a high speed, the centrifugal force is generated in the storage device. The striated body is not deformed because it is not subjected to the striated body.
Further, when the wire storage mode is not set, no striated body remains in the wire storage device, and no waste of the striated body occurs.

Further, since the plurality of wire storage rolls are arranged along the running path of the striated body, the pass line on the entrance side of the striated body and the exit side even if the storage amount is large and the number of the storage rolls is large. And no deformation such as twisting of the striatum occurs.

Furthermore, since the striated body can be passed through the storage device only by passing between the vertically open storage rolls in the storage device, troublesome wire-laying work is not required, and workability is improved. Can be significantly improved.
