2. Description of the Related Art In the fields of civil engineering and construction, various cables are used for various types of reinforcement and tension. Conventionally, such a cable is wound on a reel and wound up in a coil shape, and when used, the reel is rotatably suspended on a stand, and the cable is sequentially pulled out while rotating the reel.

[0003]

In recent years, a fiber-resin composite cable in which a fiber bundle is impregnated with a resin and twisted to form a rope structure has been used as a wire for reinforcement or tension. It is becoming. Such a fiber-resin composite cable is lightweight and has a strong elastic restoring force against bending. Therefore, when the cable is wound into a coil shape, a strong resilience tends to return to a straight state. Special measures must be taken.

That is, when the fiber-resin composite cable wound on the reel is fed, the reel tends to rotate in the direction in which the coil can be unwound due to the strong repulsive force of the cable. Equipment must be installed.

In order to prevent the cut end of the cable which has been fed out to a predetermined length from jumping by a repulsive force when cutting the cable, the cable on the coil side to be the cut end is previously held by a gripping means. Tedious and cumbersome work of having to grip with a cradle is required.

As described above, in the related art, it is necessary to take troublesome measures when feeding out the cable or cutting the cable that has been drawn out to a fixed length.
Further, there is a disadvantage that the efficiency is reduced.

The present invention has been made in view of such a point, and an object of the present invention is to make it possible to smoothly pull out a cable from a coil simply by pulling out the cable even if the cable has strong resilience. The present invention also provides a cable feeding device capable of easily, efficiently, and safely cutting a cable fed out to a predetermined length even when the cable is cut to a fixed length, without taking measures for its resilience. It is in.

[0008]

In order to achieve the above object, the present invention provides a rotatable case capable of accommodating a coil of a cable, and an inner side of the coil accommodated in the case. And a cable pull-out guide is provided so as to be arranged at a fixed position, and the cable drawn from the coil is sequentially pulled through the guide, and the cable is fed while rotating the case.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. The feeding device according to the present invention includes a case 1 having a circular trough shape, and the case 1
The case 1 and the case 2 are each formed of a synthetic resin such as polyethylene, for example.

The case 1 has an inner diameter of 1050 mm, for example.
An opening 3 having a depth of 150 mm and an inner diameter of 800 mm is formed on the upper surface of the cover 2.

A turntable 4 is mounted on the lower side of the case 1 as a rotating means. The turntable 4 has a plurality of rollers 5 on its lower surface. It is designed to be able to rotate around.

Reference numeral 6 denotes a metal base plate, and a metal support 7 is erected at the center of the upper surface of the base plate 6 by welding or the like. A through hole 8 through which a column 7 can be penetrated is provided at the bottom of the case 1 and at the center of the turntable 4.
Are formed. The column 7 is inserted into the case 1 from the lower side of the case 1 through the through hole 8.

When the column 7 is inserted into the case 1, the base plate 6 is arranged on the horizontal installation surface A, and the rollers 5 of the turntable 4 are arranged on the base plate 6. As each roller 5 rolls on the base plate 6, the case 1 rotates integrally with the turntable 4 in the circumferential direction about the support 7 as a central axis.

An arm 9 is detachably attached to the upper end of the support column 7 via a bolt 10, and a guide 11 is attached to a tip end of the arm 9. The guide 11 is a pipe-shaped member made of a synthetic resin such as vinyl chloride, and has an outer diameter of 50 mm and an inner diameter of 40 m.
m and length are 350 mm.

The guide 11 is supported at a position deviated from the center of the case 1 toward the peripheral surface thereof, and when the cover 2 is attached to the case 1 as shown in FIG. The rear end 11a is inclined and fixed to the arm 9 so that the rear end 11a is located slightly below the surface of the opening 3 of the cover 2 and the tip end 11b is located slightly above the surface of the opening 3.

Next, a description will be given of a procedure for using the feeding device configured as described above. The cable C is manufactured by twisting the strand of the carbon fiber impregnated with the thermosetting resin around the outer periphery of the strand of the carbon fiber core impregnated with the thermosetting resin, and curing the resin. Done 7
It is a fiber-resin composite cable (hereinafter, simply referred to as a cable) having a main twist structure. The cable C has an outer diameter of 7.5 mm and a length of 600 m.

When the cable C is manufactured, the cable C is first aligned with a reel having a detachable side plate and wound up to form a coil C1, and after winding up, the coil C1 is wound.
After that, the side plate of the reel is removed, and the coil C1 is removed from the reel. This coil C1
Has an outer diameter of 1000 mm, an inner diameter of 850 mm, and a height of 13
At 0 mm, the winding start end of the cable C is arranged on the inner periphery, and the winding end end is arranged on the outer periphery. That is, the cable C is wound almost in an orderly manner from the inside to the outside of the coil C1.

Next, the coil C1 of such a cable C
Is stored in the case 1, and the cover 2 is attached to the opening of the case 1, and the cable C is transported to the use site in this state.

At the point of use, the column 7 is inserted into the case 1 from the lower side of the case 1 through the through hole 8, the rollers 5 of the turntable 4 are arranged on the base plate 6, and the upper end of the column 7 is The guide 11 is attached via the arm 9.

Thereafter, the end of the cable C exposed on the inner periphery of the coil C1 is pulled out, and this end is passed from the rear end 11a of the guide 11 to the front end 11b. To the side about 500 mm. Then, the fastening band of the coil C1 is removed.

In this state, the end of the cable C led out of the guide 11 is slowly pulled. Due to this pulling, the case 1 and the coil C1 rotate about the support 7 on the base plate 6 integrally with the turntable 4,
By this rotation, the cable C is sequentially fed out from the inner peripheral side of the coil C1 in a certain direction.

As described above, the cable C is fed out while the coil C1 is rotated integrally with the case 1, so that the cable C is not twisted during the feeding.
When the cable C is pulled out from the guide 11 and the hand is released from the cable C and released, the rotation of the case 1 is stopped.

Although the cable C has a strong resilience to bending, the cable C is fixed at the position by friction with the guide 11, so that even if the cable C is released, the case 1 can freely move due to the repulsive force of the cable C. Rotating or cable C
There is no swinging.

When the cable C pulled out from the guide 11 by a predetermined length is cut and its cut end is released,
The cable C on the coil C1 side is restrained at that position by friction with the guide 11, and is fixed, so that there is no danger that the cut end of the cable C will jump off due to its repulsive force. In addition,
When cutting the cable C, it is preferable to cut the cable 11 so that an extra length of about 500 mm or more remains from the guide 11 to the front side thereof.

The case 1 and the turntable 4 are preferably as light as possible in order to reduce the rotational moment of inertia. In order to reduce the weight, the case 1 may be formed in a cage shape made of steel or synthetic resin. is there. As means for rotatably supporting the case 1, a plurality of rollers may be directly attached to the outer bottom of the case 1, in addition to using the turntable 4.

In addition to using a pipe-shaped member as the guide 11, for example, a roll pair or a belt pair can be used. In this case, the cable C is gripped by sandwiching the cable C between the roll pair or the belt pair. It is also possible to incorporate a brake mechanism in advance in the rotating part of the roll pair or the belt pair, or to attach a friction member such as rubber to the surface of the roll or the surface of the belt.

When a pipe-shaped member is used as the guide 11, it is important to use a harder material than the cable C as the material of the guide 11 so as not to be damaged early by friction with the cable C.

The position and angle of the guide 11 are determined by the coil C
1 is appropriately determined according to the winding diameter and height of the coil C1, but the arrangement position is preferably as close as possible to the inner circumference of the coil C1 and approximately the same as the height of the coil C1. It is preferable to set it to about 30 °.

It is needless to say that the feeding device of the present invention can be used not only for feeding a fiber-resin composite cable, but also for feeding a steel cable.

[0030]

As explained above, according to the present invention,
Even if the cable has a strong resilience, the cable can be smoothly drawn out of the coil simply by pulling out the cable, and the measure against the resilience when the cable drawn out to a predetermined length is cut to a fixed length. Can be easily and efficiently and safely cut without taking any special measures.
