SOLUTION: When the linear body 25 is closely wound without overlapping in an annular tank partitioned by an outer wall 4, an inner wall 3 and a floor 5, load applied to the linear body can be decreased. A revolving frame 11 is revolved taking the center of the tank as the center of revolution in the direction of an arrow by a rotary driving motor. A guide arm 12 is rotatably supported round a shaft 13 provided on the outer periphery of the revolving frame 11, and in the drawing, all of twelve guide arms 12 are simultaneously expanded and contracted. An equivalent circle 35 which is an envelope changes from 35a to 35d of Fig. 1 (a). The linear body 25 is fed at a constant speed from the upper part of the center of the tank and grounded at a grounding point 30 through an illustrated locus. The revolving speed of the revolving frame 11 and the diameter of the equivalent circle 35 of the guide frame 12 are controlled to wind the linear body along the outer wall or inner wall of the tank so that load applied to the linear body can be reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for arranging filaments in a tank temporarily stored when a long filament such as a submarine cable is manufactured. To a winding device.

[0002]

2. Description of the Related Art When manufacturing a striated body such as a submarine cable,
Usually, in order to continuously manufacture a cable having a length of several tens km to several hundred km, the manufactured striated body is temporarily stored in a cylindrical storage space called a so-called tank.
The tank has, for example, as shown in FIG. 7, a concentric cylindrical inner wall 3 and an outer wall 4 provided on a flat floor surface 5, and an annular storage space formed by the inner and outer walls and the floor surface serves as a tank. It is used, and a striated body hanging from a ceiling or the like is spirally wound and stored in layers.

[0003] In order to accommodate the striated body in the tank, the striated bodies are aligned in the tank in accordance with the supply speed of the striated body so that an unreasonable external force does not act on the striated body. The striatum is wound in an arc shape along the inner wall or the outer wall, and spirally arranged without gaps. 7 and 8 schematically show a conventional method of aligning and housing the striatum in the tank. FIG. 7 shows a method of arranging the striatum by manual power. FIG. (B)
FIG. 3 is an elevational view showing a cross section at the center of the tank. FIG. 8 shows an alignment method for guiding the striatum with a guide roller movably supported in the tank. FIG. 8A is an elevational view showing a cross section at the center of the tank, and FIG. Side view of a guide roller portion that restricts and guides to a predetermined position,
(C) is a plan view thereof. Note that the relational positions between (b) and (c) are projections of the single angle method.

With reference to FIG. 7, a method for manually aligning the striatum will be described. The manufactured striated body 25 is sent above the tank, the course is changed to a substantially right angle by the guide mechanism, and then descends toward the center of the tank. A routing member 51 on a circular platform installed at the center upper part of the tank holds the striatum 25 with both hands and turns the striatum at the lower level according to the supply speed while turning clockwise as viewed from above. Hand them to the line-up. As an example, FIG.
In FIG. 7A, there are 12 aligning personnel, and at the moment shown in FIG. 7, the 1st to 5th aligning personnel actually support the striatum and are aligned along the inside of the outer wall. The first alignment member arranges the striated body 25 in an arc on the tank floor.
The point at which the striatum 25 reaches the floor is the landing point 30. The other No. 2 to No. 5 staff members support and guide the striatum in the air so as to gradually draw an ellipse while gradually approaching the floor, and perform the same operation as No. 1 in order. Line up.

[0005] With the movement of the striatum, alignment staff Nos. 6 and 7
The striated body 25 is directly received from the staff 51 by being routed one after another. On the other hand, No. 1 of the rearranging personnel who is separated from the striatum 25 walks on the elliptical orbit and re-routes to the rear end of the line for receiving the striatum from the personnel. The elliptical orbit drawn by the alignment staff rotates clockwise with the long diameter end where the alignment staff 1 is located close to the tank outer wall in the figure. When the one layer of the striated body 25 is spread on the floor 5, the second layer is similarly wound on the first layer without any gap. If the first layer is aligned from outside to inside, the second layer is aligned and wound from inside to outside.

[0006] In contrast to the manual alignment method of FIG.
An alignment method using a guide roller will be described below. FIG.
As shown in (a), the temporarily stored filament 25 is fed from the outside of the tank shed 23 at a supply speed synchronized with the production speed of the filament, for example, a feed mechanism installed on the shed. 20
Then, the traveling direction is changed from horizontal to vertical by the guide mechanism 21, and then descends vertically toward the center point of the tank. Where the striated body penetrates the shed 23, a mouthpiece 22 is often provided for protection. This configuration has almost the same structure even in the case of manual power. The striated body 25 is guided by a guide roller 32 movably supported between the inner wall 3 and the outer wall 4, and lands at the landing point 30 and aligns.

The guide roller 32 is supported by a horizontal arm 33 and a vertical arm 34. The guide arm 32 pivots the horizontal arm 33 clockwise, and at the same time, moves its tip in the radial direction of the tank so that the striated body 25 is at a predetermined position. Lead. Striatum 25
Are stacked, the vertical arm 34 is moved up and down so that the guide roller is adjusted to an optimum height from the landing point. The turning speed of the horizontal arm 33 is made equal to the supply speed of the filament, and the guide roller 32 is fed at a speed corresponding to the outer diameter of the filament 25 in the radial direction of the tank for each revolution. A small number of alignment personnel (correction personnel) may monitor and correct any irregularities in the striatum 25. The linear body 25 includes a vertical roller 32a and a horizontal roller 32b attached to the guide roller 32.
Is inserted from the direction of the arrow into the substantially square hole formed by
You will be guided. Further, the landing is guided by a rear vertical roller 32c and a rear horizontal roller 32d to make the landing position accurate. The guide roller 32 uses a number of rollers, and
However, depending on the stiffness and other characteristics of the striated body 25, the striated body 25 may sometimes stay near the guide roller.

As shown in FIG. 7, only human power requires at least 10 (13 in this example) personnel. If the guide roller 32 shown in FIG. 8 is used, it is only necessary to correct a slight gap or overlap between the striated bodies due to the dispersion of the guide roller position and the landing point of the striated body, and alignment can be performed by a small number of personnel. Since the latter alignment method using the guide roller requires only a small number of alignment members, it is frequently used when the filament 25 is a coaxial cable.

[0009]

However, recently, optical fibers have been frequently used as submarine cables.
When an optical fiber is used as a striatum, the following problems occur with respect to a conventional coaxial cable. In the case of temporary storage in the tank as described above, if there is a gap due to turbulence or overlapping of the striatum, an unacceptable load is applied, and there is a high risk of damaging the cable. In the case of an optical fiber, in particular, it is necessary to strictly align the optical fibers, and it is necessary to take measures to surely avoid gaps and overlaps. In addition, guidance by the guide roller requires a certain amount of restraining force on the striatum, and the guide roller exit (restraint portion exit side)
If the feeding of the striated body is delayed, the striated band may be deformed more than allowed and may cause decisive damage.

Therefore, when the striated body is an optical fiber, a guide roller cannot be used like a coaxial cable to align the striated bodies in the tank, and a system using only human power as shown in FIG. 7 is used. I had no choice. This requires the use of more than 10 routing and alignment personnel, which makes it impossible to reduce labor costs. In addition, the environmental conditions in the tank are not comfortable, and the work is particularly severe in summer and winter, and the work conditions are poor. In addition, the maximum length of an optical fiber can reach as much as 150 km, and once production begins, it lasts for several days, making it difficult to interrupt the operation midway. Improving work conditions for personnel is urgently needed.

[0011]

In order to solve the above-mentioned problems, a rotating center is provided at the center of an annular storage space for spirally winding and storing a filament, and is parallel to the bottom surface of the storage space.

There is provided an induction winding device, comprising: a guide arm expanding / contracting drive mechanism capable of expanding / contracting at a constant rate; and a turning drive mechanism for turning / driving the turning frame.

Further, the turning speed of the turning frame is controlled so that the feeding speed of the wire and the landing speed of the wire are equal, and the equivalent circular radius of the turning arm is equal to that of the wire. The present invention provides an induction winding device that controls expansion and contraction according to the landing point radius.

Provided is an induction winding device having a pivot arm that connects one end of members having a mirror image relationship with each other and further reinforces an intermediate point of the pivot arm with a support. Also, the swivel arm may be formed in a fan shape with a flat plate, and the swivel arm may be inclined when the equivalent circle is reduced. Further, the guide winding device is configured such that the swing arm is formed in a truncated cone shape lacking at least a trapezoidal bottom surface, and the small diameter bottom surface side of the swing arm is fitted into the large diameter bottom side of the adjacent swing arm. Also provide. Further, the guide arm forms a flexible pipe into a circle equal to the equivalent circle, or

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A turning guidance device according to an embodiment of the present invention will be described with reference to FIGS. FIG.
(A) is a conceptual plan view of the turning guidance device 1 installed near the center of the tank 2 which is a storage space, and FIG. 1 (b) is a side view cut along a plane passing through the turning center of the turning guidance device 1. is there. (A) further shows a part as a cross section.
FIG. 2 shows one mechanism for turning and expanding / contracting the turning guidance device 1.
An example is shown, FIG. 2A is a side view in which a partial cross section near the turning frame of the turning guiding device 1 is used together, and FIG.
FIG. 2 is a plan view of the turn guidance device 1 taken along a line AA in FIG.

A cylindrical inner wall 3, a cylindrical outer wall 4 at the same center as the inner wall 3, and an annular space delimited by a tank floor 5 are used as the tank 2 as a storage space for the striated body 25. Is done. The approximate size of the tank is, for example, the inner diameter of the outer wall is about 10 to 20 m, the outer diameter of the inner wall is 2 to 4 m, and the inner and outer walls have a height at which the striatum can be stacked up to 2 to 4 m.

A turning guide device 1 is provided by a bearing frame 7 fixed to the upper center of a fixed frame 6 formed at the center of the tank 2.
Is supported. Swing drive motor 10
1 rotates the revolving frame 11 clockwise as indicated by an arrow in FIG. 1A via a pinion 9 and a revolving bearing 8 with gears fixed to the revolving frame 1. Disc-shaped revolving deck 16 and, for example, top guide 1 formed of steel pipe
7 is fixed to the revolving frame 11 by a plurality of columns 16a, and is used as a guide for the descending filament 25.
These are also turned by the rotation of the turning frame 11.

A plurality of guide arms 12 (in this example, twelve) are mounted with one end rotatably supported by a guide arm shaft 13 formed near the outer periphery of the revolving frame 11. The guide arm 12 is made of, for example, a steel pipe, and is a part of a chord winding having a plane projection shape that is an arc having a diameter substantially equal to the outer diameter of the revolving frame, and the angle constituting the arc is, for example, about 180 ° in this example. Have been. By a mechanism described later, the guide arm 12 is rotatable about the guide arm shaft 13 as a center of rotation, and the rotation of all the guide arms is synchronously rotated by the same angle. Accordingly, an equivalent circle 35 (abc), which is the envelope of the outer circumference of the plurality of guide arms 12, is formed, and the center of each equivalent circle 35 (abc) always coincides with the rotation center of the turning frame, and the rotation of the guide arm 12 is performed. Accordingly, the outer diameter of the equivalent circle 35 formed on the outer periphery expands and contracts.

In the guide arm 12a shown by the two-dot chain line in FIG. 1A, the equivalent circle is 35a, which is almost the maximum radius as the equivalent circle. When the guide arm 12a rotates and contracts to 12b, the equivalent circle becomes 35b, and
In the case of c, the equivalent circle is 35c. Guide arm 12a
The equivalent circle 35d is also minimum when 12d is reduced until the rotating frame 11 comes into contact with the rotating frame 11, and the diameter thereof is substantially equal to the outer diameter of the rotating frame 11. As described above, by controlling the rotation angle of the guide arm 12, an equivalent circle having an arbitrary radius can be obtained.

The striated body 2 temporarily stored in the above-mentioned tank 2
Numeral 5 is horizontally moved over the shed 23 of the tank 2 by a feed mechanism (not shown), changes the traveling direction vertically by the guide mechanism 21, passes through the bell mouth 22 installed in the shed, and guides the turn. It descends on the device 1. Striatum 25
Is guided so as to ride on the top guide 17 and the guide arm 12, since the turning guide device 1 is rotating clockwise, for example, the striatum 25 is rotated in the rotating direction of the turning frame 11 by friction with the guide arm 12. Figure 1
, And lands on the landing point 30 by drawing a locus schematically shown in FIG.
The trajectory is indicated by a dashed line in FIG.
In this case, the striated body 2 with respect to the turning speed Vr of the equivalent circle 35
If the supply speed Vl of V5 becomes slightly slower, Vr> Vl, the direction of the landing point 30 is stabilized, and it becomes effective as aligned winding. The turning speed Vr of the equivalent circle 35 is, of course, the same as the turning speed of the turning frame 11. If the weight per unit length of the filament 25 is the same, the filament 2
The position of the landing point 30 in the tank radial direction is substantially determined by the radius of the equivalent circle 35a formed by the guide arm 12. Therefore, it is possible to control the landing position by adjusting the radius of the equivalent circle 35 on the outer peripheral side formed by the guide arm 12. Although the turning guide device according to the embodiment of the present invention has been described as winding the filament 25 clockwise, it may be wound counterclockwise depending on the twisting direction of the filament 25. In this case, the revolving frame 1 can be easily replaced by replacing some components with a mirror image.
1 can be handled by reversing the rotation direction.

As described above, the striated body 25 is
2, the filament 25 is dragged in the rotation direction of the revolving frame 11 by friction with the guide arm 12, and lands at a landing point 30 near the equivalent circle 35. However, the striated body 25 is restrained only by the frictional force, and is hardly restrained in shape. Therefore, there is no danger of receiving an external force exceeding the allowable limit due to a change in the supply speed of the striated body 25 or the like.

The turning mechanism of the turning frame 11 and the expanding and contracting mechanism of the guide arm 12 will be described with reference to FIG. FIG.
In (a), a gear-side retainer of a gear-equipped slewing bearing 8 is fixed to a slewing frame 11, and another retainer is fixed to a bearing frame 7 installed above a fixed gantry 6. Here, the internal bearing 8a may be provided to receive the center of the revolving frame 11, and a universal coupler, a slip ring, or the like that transmits power above the revolving frame may be housed. A pinion 9 meshing with the teeth of the geared turning bearing 8 is fixed to an output shaft of a turning drive motor 10, and the turning drive motor 10 causes the turning frame to turn clockwise.

At least one of the plurality of guide arms 12 has a guide at a bearing portion fixed to one end of the guide arm 12 and fitted to a guide arm shaft 13 implanted near the outer periphery of the revolving frame 11. Arm expansion / contraction link 14
Has been fixed. One end of the linearly moving actuator of the guide arm expansion / contraction drive device 15 mounted on the revolving frame 11 is connected to the tip of the guide arm expansion / reduction link 14 to rotate the guide arm 12 by, for example, about 90 °. An interlocking link 18 is fixed to a bearing portion of the guide arm 12, and the interlocking link 18 of the adjacent guide arm 12 is connected by an interlocking rod 18a. And the same angle rotation. As shown in a series of guide arms 12 on the left side of FIG. 2B, the link mechanism may be linked with a chain wheel 19 and a chain 19a instead of the link mechanism in the linking method using the link mechanism. In addition, tension is applied to the chain 19a by the auxiliary chain wheel 19b, and the chain 19a is tensioned to prevent slack.

In this embodiment, twelve guide arms 12 are used. When the guide arms 12 are reduced, they surround the turning frame 11 without any gap. To avoid interference between the guide arms 12,
The guide arm is supported at an angle of about 8.5 °.
A guide arm (12) indicated by a broken line in FIG. 2A shows a state in which the guide arms overlap each other at the time of reduction as a cross section of a steel pipe. Strictly speaking, the shape of the guide arm 12 is
It becomes a part of the helical winding that constitutes the 12th thread.

In order to align the filaments 25 supplied at a constant speed in the tank 2 without gaps and without overlapping, the filaments 25 are wound, for example, along the outer wall of the tank, and It is necessary to shift inward by the outer diameter of the striatum for each circumference and land. The speed of movement of the striatum and the position of the landing point 30 are determined by the turning speed of the turning frame 11 and the guide arm 12.
Is determined by the size of the equivalent circle 35 formed by the rotation drive motor 10 and the guide arm enlargement / reduction drive 1
5 may be controlled.

As an operation method for storing the striated body 25 in the storage space, a manual operation in which the operator controls the guide arm enlargement / reduction drive device 15 while watching the winding position of the striated body 25, Automatic measurement of the position in the storage space or automatic calculation from the amount of entanglement, equivalent circle 3
Any of the automatic operations in which the operation is performed by determining the outer diameter of 5 can be performed. Further, it is sufficient that the turning speed of the turning frame 11 is always automatically set by calculation and adjusted by an operator as needed. When the guide arm 12 is reduced to a minimum diameter at the time of so-called pay-out work, in which the striated body 25 is wound into a winding frame from the storage space where the striated body 25 is temporarily stored, the diameter becomes the same as the inner wall 3 of the tank. So that the guide arm 1
The striated body 25 and the guide arm 12 do not interfere with each other during the dispensing operation only by reducing the size of the guide arm 12.

Various forms of the guide arm are conceivable other than those described above. Even when the above-described steel pipe is bent into a substantially semicircular shape, there is a deformation as shown in FIGS. FIG. 3 (a1) shows a planar shape, FIG. 3 (a2) shows a side shape, and FIG. 3 (a3) shows a trajectory of movement, which is an example of a guide arm 12a, which can be called a double-armed system. In addition, the side shape shows only the center and three guide arms on the left and right sides to avoid complication. The circumference of the guide arm shown in FIG. 1 is enlarged, for example, to 290 °, the expansion / contraction mechanism is moved to the upper part of the revolving frame 11, and a roller is attached opposite to the bearing side to slide on the sub-revolving frame 11a. It is stable because it can receive the load at both ends of the guide arm. still,
A guide arm 12a is provided at the center of the sub-rotating frame 11a.
There is a space that does not enter, and the upper structure is supported using this space.

The guide arm 12b of the double-armed arm type (part 2) shown in FIG. 3 (b1) in a plan view and FIG. 3 (b2) in a side view has a spiral having a mirror image relationship with the guide arm 12 in FIG. With a structure where the arm is joined at the tip,
Since it is supported at the same position in the vertical direction, a very stable configuration is obtained. Since the guide arm enlargement / reduction drive device 15 and the interlocking mechanism (both not shown in FIG. 3) can be moved to the lower sub-rotating frame 11a side, the center of gravity is lowered, and the stability is further increased.

The guide arm 12c of the double-armed arm system (No. 3) shows a plan view in FIG. 4 (a1), a side view in (a2), and a locus of its movement in (a3). The center of the circumference of the guide arm 12 shown in FIG. 1 is supported by a column 12d, and both the revolving frame 11 and the sub-revolving frame 11a are provided with an equivalent of the guide arm shaft 13, so that the guide arm 12c and the column 12d are connected. It can be received and is stable in strength. Further, as shown in FIG. 4 (a3), since the support 12d stays at the outer edge of the revolving frame 11, the available space in the revolving frame 11 is large, and the internal structure of the revolving frame 11 is reasonable.

The guide arm is not only made of steel pipe,
A flat guide arm 12e can also be used. The case where the radius of the equivalent circle is the largest is shown as a plane shape in FIG. 5 (a1) and as a side surface shape in (a2). As an example, a fan-shaped member 12 e obtained by dividing the maximum equivalent circle into eight equal parts is used as a linear motor actuator 12.
f, and as the outer diameter decreases, the guide arm 12
e is tilted by a tilt drive motor (not shown). Here, the revolving frame 11b is made of cylindrical sheet metal, and the inside is drawn as hollow. The linear motor body is fixed to the turning frame 11b. The case where the equivalent circle is minimized is shown as a plane shape in FIG. 5 (b1) and as a side surface shape in (b2). The guide arm 12e is substantially concentric when viewed from above, and is the smallest equivalent circle.

Although it is easy to mount a linear motor and an inclination drive motor on each of the guide arms 12e and control them collectively, a guide arm 12g in which a support 12g1 is integrally attached to the guide arm 12e can also be used.
As shown in FIGS. 5 (c1) and (c2), the turning frame 11
At a predetermined position b, an oblong hole 11c is formed which is inclined and has the same cross-sectional shape as the support 12g1, and the support 12g1 is inserted and supported. Although only one elongate hole 11c is illustrated in the figure, the same number of the elongated holes 11c as the guide arms 12g is formed. Prop 12
The g1 is twisted to give an inclination as shown in (1), (2) and (3) of FIG. 5 (c1), and the inclination of (3) at the time of the maximum equivalent circle is made equal to the inclination of the elongated hole 11c. Revolving frame 11b
When the guide arm 12g is expanded / reduced by a guide arm expansion / reduction drive device (not shown) installed inside, the guide arm 12g has a large inclination when it is contracted, and becomes flat without being inclined when it is enlarged. As described above, various driving methods can be mechanically adopted.

By changing the overlapping amount of the members constituting the guide arm, it is possible to cope with a change in the circumferential length of the equivalent circle.
FIG. 6A is a perspective view of this example. The guide arm 12f is formed by forming the side surfaces of a truncated cone with a sheet metal, and is combined so that the smaller radius of the bottom surface enters the larger one of the bottom surfaces. In the figure, 16 truncated cones are successively overlapped. The minimum required for the guide arm 12f is a conical surface, and at least the large-diameter bottom surface must be removed. A telescopic mechanism 24, generally called a pantograph, and an actuator 24a of a linear motor are attached to the center of the conical surface every other guide arm 12f, and the telescopic mechanism 24 and the actuator 24a expand and contract in synchronization with each other. The circle expands and contracts. The intermediate guide arm 12f is connected to the adjacent guide arms 12f by an automatic alignment mechanism 24b, and is always inclined at the same angle with respect to the guide arms on both sides. For example, telescopic mechanism 2
When the guide arm 12f fixed to the distal end moves outward, the guide arm 12f located in between also moves outward, and is inclined at an equal angle to both sides. That is, when the radius of the equivalent circle changes, the guide arm 12f becomes substantially a regular polygon (16 sides in FIG. 6A) in accordance with the radius. According to the change of the radius of the equivalent circle, each guide arm 12f
The conical surface of the small bottom slides into or out of the conical surface of the large bottom to have a predetermined circumferential length. It can correspond to an equivalent circle up to less than twice the minimum equivalent circle. In FIG. 6 (a), the expansion mechanism 24 and the actuator 24a of the linear motor are mixed for explanation, but only one of the expansion mechanisms may be used. Further, a part of the outer periphery of the guide arm 12f can be rotated in the direction of the arrow like 12f1, so that the frictional force with the striated body 25 can be reduced.

The example shown schematically in FIG. 6B as a perspective view uses a flexible pipe for the guide arm 12h, and is formed in a single string winding with some overlap at the time of maximum enlargement. ing. In the figure, the guide arm 12h is supported by nine extension mechanisms 24c, and at the same time, the extension mechanism 24c expands and contracts to change the radius of the equivalent circle of the guide arm 12h. Certain types of flexible pipes have the property of being able to expand and contract in the length direction, so that the adjacent expansion mechanism 24c
The length S of the guide arm 12h between the
Expands and contracts according to the change in length. In FIG. 6B, both ends of the guide arm 12h are cut and shown.
Individual rings may be used.

When a flexible pipe is used for the guide arm 12h but does not expand or contract in the longitudinal direction, a single-layered pipe having some overlap at the time of maximum expansion is used as shown in FIG. 6 (b). It is formed on the string winding. The point that the guide arm 12h is supported by the extension mechanism 24c and the extension mechanism 24c expands and contracts to change the equivalent circle of the guide arm 12h is the same as the above example. The expansion / contraction mechanism 24c is connected to two-step grooves 11e and 11
f, the radial direction of the telescopic mechanism 24c can be changed, and the angle θ between the adjacent telescopic mechanisms 24c is controlled so that the partial length s of the guide arm is equivalent to the arc length. Can be formed. The apex angle of the fan is determined in inverse proportion to the length from the center of the turning frame 11d to the guide arm, so that it can be easily controlled.

FIG. 6 (b) shows a state where it is enlarged to a substantially maximum equivalent circle. The smallest equivalent circle is the revolving frame 11d
This is when the guide arm is wound almost double. Since the extension mechanism 24c is housed separately in the two-step grooves 11e and 11f, interference does not occur even if the mutual angle θ increases. As the guide arm 12h, a pipe having a structure usually called an armored pipe (the cross section is not limited to a circle but may be a rectangular cross section) can be used. According to the above description, it is possible to use a flexible pipe which can be expanded or contracted in the length direction or not.

[0035]

As described above, by employing the induction winding device of the present invention, the number of personnel required to align the striated bodies in the tank can be greatly increased even for an optical fiber submarine cable. It is possible to reduce. Although some modification of the landing point requires monitoring personnel and assistants for alignment, at least half of the conventional alignment personnel have been reduced. Further, in the present invention, since the restraining force of the striated body is small, there is no concern that a large external force due to stagnation is applied to the striated body, so that the work can be performed with peace of mind.
