[0002]

2. Description of the Related Art In general, when a long cable is laid and laid over a long distance, a large tension is applied to the cable. Work to be sent to the section. When winding and storing the cable at the intermediate point in such an operation, a cable drum is used. In this cable drum, a cylindrical cable winding member is attached between two circular side plates. A cable is wound around the outer periphery. When laying cables, install a cable drum at one end of the section where
An empty cable drive at the middle point

I was

However, the cable taken in the middle is temporarily wound on a cylindrical drum, and is stacked on the ground in a ring shape.
If the cable is twisted after being piled up, the cable may be twisted. Therefore, as disclosed in Japanese Patent Publication No. 62-34444, the cable to be taken is temporarily placed on the ground in the form of a figure 8 and accumulated. , Turn this figure-eight bundle upside down
A method in which the tip of the cable is fed out after turning is adopted. According to this, when the cable is fed again, the twist is cancelled, so that there is no trouble in laying, and the cable can be fed well.

[0004]

However, according to the above-mentioned conventional method, the cables are laid one on top of the other in a figure eight shape on the ground, and when the cables are pulled out, the bundle of the stacked cables is turned upside down and the cable ends are turned up. The following problems have arisen since the delivery was made after the delivery.

That is, according to the above-mentioned conventional method, the intersection of the figure 8 may be deformed by the weight of the cable.
In addition to requiring a large number of workers, there is a risk of damaging the cable. In addition, there is a limit to the length of the cable that can be turned upside down, and there is a limit to the length of the laying / interconnecting.

From such a viewpoint, as shown in FIG. 4, it is conceivable to install a pair of drums 1 and 2 horizontally and wind the cable 3 around the pair of drums 1 and 2. This is achieved by successively tapping both drums 1,2.

However, in such a method, one intersection 4 is generated per cable when winding around the drum. Since this intersection 4 corresponds to two cable widths,
There is a problem in the case where an optical fiber cable is a target, particularly in a case where the intersection is easily damaged. In addition, since the crossing portion 4 protrudes during the winding on the drum and the amount of winding is limited, the above method can accommodate only half the amount of the cable 3 that is tightly wound around the drums 1 and 2. There is a problem that can not be.

SUMMARY OF THE INVENTION An object of the present invention is to pay attention to the above-mentioned conventional problems and to prevent a cable crossing portion from restricting tight winding around a winding body while preventing twisting when a cable is fed out. It is another object of the present invention to provide a cable winding and housing method capable of winding and housing a cable densely by the length of the winding body.

[0009]

In order to achieve the above object, a cable winding and accommodating method according to the present invention provides a method for winding a cable on a winding frame having a pair of cable winding bodies arranged at intervals. A method of winding and housing, the direction crossing a center connection line of a first wound body and a second wound body.
And wound around the second wound body through a cable, and then passed from the second wound body to the first wound body in a direction parallel to the center connection line of the first wound body. A cable is wound in a reverse cross direction from the first wound body to the second wound body, wound around the second wound body, and passed from the second wound body to the first wound body in parallel to the first wound body. A series of winding operations, such as winding, is repeatedly wound and accommodated.

[0010]

According to the above construction, one intersection occurs between two windings of the cable around the winding body. Therefore, the width of the winding on the winding body coincides with the width of the intersection. Only the cable does not overhang, and the cable can be tightly wound around the wound body. The wound cable is in a figure-eight wound state, and can be pulled out while canceling the twist in the cable at the time of feeding.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the method for winding and storing a cable according to the present invention will be described below in detail with reference to the drawings.

First, a winding frame 12 for winding the cable 10
Will be described with reference to FIG. As shown in this figure, the bobbin 12 includes a support 16 standing upright on a base 14 so that it can be erected on the ground. In addition, the upper and lower portions of the support 16 are respectively provided with winding bodies 18A, 18
B are cantilevered and are mounted in parallel, spaced apart vertically with their openings facing each other. The diameter of these winding bodies 18A and 18B may be set according to the degree of curvature allowed for the cable 10 to be wound, and in this embodiment, the diameter is set to about 500 mm. It is desirable that the length of the wound bodies 18A and 18B be as long as possible in order to increase the capacity, but it may be determined in relation to the cable weight. In the embodiment, the length is also set to 500 mm.

[0013] The cable 10 is
Is carried out as one cycle of the winding shown in FIG. That is, the winding start end 10S of the cable 10 is connected to the upper and lower winding bodies 18A, 18A of the winding frame 12.
3B, the two wound bodies are extended from one side edge of the upper first wound body 18A to the opposite side edge of the lower second wound body 18B as shown in FIG. 18A, 1
8B is guided in a cross direction crossing the center connection line. Then, after being wound around the lower second winding body 18B, this time, the upper first winding body 18A and the upper winding body 18B are tangentially extended in parallel with the first winding body 18B.
The first winding body 18A is wound around the first winding body 18A. Thereby, the cable 10 is connected to the first winding body 1.
8A is located on the opposite edge to the first cable entry.

Thereafter, as shown in FIG. 3 (2), the cable 1 is turned from the first winding body 18A to the second winding body 18B again, but this time, the cable 1 is turned in the cross direction opposite to the previous cross direction.
0 is introduced to reach the lower second wound body 18B and wound. As a result, the cable intersection 20 is formed between the two winding bodies 18A and 18B for the first time. Then, the cable 10 wound around the second winding body 18B is extended in parallel upward, and is wound around the first winding body 18A to reach the first introduction portion. This completes one cycle of the winding operation. The winding state of the cable 10 is shown in FIG.

Thereafter, by repeating FIGS. 3 (1) and 3 (2), the cable 10 is wound tightly and accommodated in both the winding bodies 18A and 18B from the column side to the tip. .

In the cable 10 wound and accommodated in this manner, one intersection 20 occurs between two cables wound around the winding bodies 18A and 18B. Therefore, even when the cable 10 is tightly wound around the winding bodies 18A and 18B, the width of the intersection 20 does not protrude beyond the winding width, and the cable 10 around the winding bodies 18A and 18B does not protrude.
The winding amount and the overlapping width of the intersecting portion 20 can be matched and wound and accommodated. Therefore, twice as many cables 10 can be accommodated as compared with the conventional figure 8 winding method.

The cable 10 housed by winding is wound to a winding frame 12.
When the cable 10 is pulled out, the end of the winding of FIG. 1 is pulled out to the side. At this time, the end of the winding of the cable 10 first comes off the upper first winding body 18A, and then the lower second winding body Twist is applied when the cable 10 is released from the upper winding 18B, and then reverse twist is applied when it is released from the lower second winding 18B and reaches the winding start end. The occurrence of twisting with drawing can be prevented. Therefore, the winding of one cycle shown in FIG.
The cable 10 can be finally laid without twist while repeating the release of twisting for each winding cycle by unwinding the cable 10.

[0018]

As described above, the cable winding and accommodating method according to the present invention is a method of winding and accommodating a cable in a winding frame constituted by arranging a pair of cable winding bodies at intervals. Then, after passing the cable from the first wound body to the second wound body in the cross direction and winding it around the second wound body, the second wound body is passed through the first wound body in parallel to the first wound body. Wound around one wound body, pass through the cable from the first wound body to the second wound body in the reverse cross direction, wind around the second wound body, and parallel from the second wound body to the first wound body. The cable is wound around the first wound body repeatedly to be wound and housed, so that the cable can be unwound without being twisted when being pulled out, and the cable is wound around the wound body. Even if tightly wound, the cable intersection becomes larger than the winding dimension Since DOO absence, taking tightly wound by an amount cable winding length in the winding body effect of efficiently accommodating obtained.
