In the automatic wire arranging system of the current optical cable, the production line runs in the left-to-right direction, the finished optical cable is clamped and sent out through crawler traction, and finally is wound on a finished optical cable winding drum through an automatic wire arranging machine body, a wire arranging arm and a clamp; when the optical cable does not rotate circumferentially along the axis, the optical cable will be neatly arranged on the finished reel. The optical cable torsion at the traction outlet is continued on the take-up reel all the time, the optical cable torsion phenomenon can be obviously observed between the clamp outlet at the front end of the wire arranging arm and the adjacent optical cables on the reel, when the torsion angle exceeds a certain critical value, the optical cable pitch can be changed rapidly, when the wires are arranged from left to right, the pitch reaches 2D (D is the current optical cable diameter), the adjacent optical cable wires can cross (when the optical cable rotates anticlockwise) or gap (when the optical cable rotates clockwise), the wires are not orderly arranged, after the optical cable passes through the wire arranging arm and the clamp, the optical cable is arranged on the optical cable reel at a certain pitch, the pitch central value is generally equal to the optical cable diameter, and when the optical cable torsion angle is smaller, the optical cable is in an orderly wire arranging state, and is an inner-layer optical cable; and winding the optical cable to a certain layer, wherein the accumulated torsion angle is larger and larger, the distance between the optical cable and the original position is also larger, when the optical cable reaches a certain critical point, the pitch is jumped, the optical cable is arranged at the original position of the outer layer optical cable, and the optical cable is directly arranged at the position of the twisted optical cable after the jump.

2) The degree of automation is low: these systems are relatively low in automation and may not adequately meet the requirements of production efficiency and quality for complex or high speed production lines.
3) Uneven flat cable: under the condition that an advanced control system is not provided, the uneven phenomenon of the cable arrangement of the optical cable possibly occurs, so that the cable arrangement on the finished product disc is not orderly, and the difficulty of subsequent treatment is increased.
4) The adjustment and maintenance costs are high: due to the lack of advanced control and monitoring systems, conventional wire dress equipment may require more frequent adjustment and maintenance, thereby increasing operating costs.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
As shown in connection with fig. 1, 3 and 4, the optical fiber 1 is the core transmission medium of the optical cable 9, and is typically located at the innermost layer of the cable. The optical fiber 1 is placed inside the loose tube 2, which acts as a protective layer around the optical fiber 1 to protect it from physical damage. The paste 3 is used to fill the space between the loose tube 2 and the optical fiber 1 and to provide additional protection and stability. A sleeve of FRP 4 surrounds the loose tube 2 and the paste 3 providing additional mechanical strength and protection. A water blocking tape 5 is wrapped around the plastic-coated FRP 4 for preventing moisture from penetrating into the inside of the optical cable 9. An aramid 6 layer is covered over the water blocking tape 5 providing additional strength and protection. The polyethylene 7 layer is used as the outermost layer to wrap the aramid fiber 6 for protecting the optical cable 9 from environmental factors. An opening cable 8 is mounted on the outer layer of the optical cable 9 for opening the optical cable 9 during installation or maintenance.

The second gear 20 cooperates with the first gear 21 to transfer the movement of the torsion control device 16 to the cable arm and clamp 10 to adjust the position and alignment of the fiber optic cable 9. On the production line, it is very difficult to twist the cable in a fast movement, because it is difficult for the device fixed to the production line to apply a sufficiently large circumferential torsion moment while keeping the cable in motion. The compression belt for the optical cable traction of the invention does not apply power in the traction direction, and is used for keeping the relative fixation of the clamping mechanism, namely the belt and the optical cable, and then applying torque for twisting the optical cable through static friction force between the compression belt 18 and the optical cable so as to control the active torsion of the optical cable.

as inventive supplementary evidence of the claims of the present invention, the following important aspects are also presented:
(1) The expected benefits and commercial values after the technical scheme of the invention is converted are as follows:
the conventional automatic wire arrangement is suitable for armored optical cables containing metal strips, the wire arrangement quality of an automatic wire arrangement machine is unreliable when the round soft optical cable is produced, and only a manual wire collection mode can be adopted, wherein the total sheath length of the round soft optical cable exceeds 40%; when realizing the automatic winding displacement of circular flexible optical cable, can greatly reduce artifical line, use manpower sparingly resource.
(2) The technical scheme of the invention fills the technical blank in the domestic and foreign industries:
it can be explicitly: the automatic wire arranging machine is the most widely used in China and is the most advanced area, and no clear evidence exists in China at present to indicate that any optical cable manufacturer or equipment manufacturer realizes the reliable use of the round soft optical cable on the automatic wire arranging machine. Once the scheme is applied to engineering, the technical blank in the domestic and foreign industries is filled.
(3) The technical scheme of the invention solves the technical problems that people are always desirous of solving but are not successful all the time:
since 2017 long-flying company optical cable part is introduced into the first automatic wire arranging machine in the industry, reliable engineering application can be realized on the metal tape armored optical cable through continuous optimization iteration, so that the labor cost is greatly reduced, and meanwhile, the upper limit of the production line speed of manual wire collection is far broken through. However, the round soft optical cable cannot be reliably applied at late time, which is always a technical breakthrough direction concerned by optical cable manufacturers and equipment manufacturers, and once the scheme is applied to engineering, the technical problem that the industry is always eager to solve but is always unsuccessful is solved:
(4) The technical scheme of the invention overcomes the technical bias:
since 2017, at least 5 equipment manufacturers have or have tried to break through this point, but unfortunately, no clear progress has been made in recent 6 years, so that the break through in this direction has been almost without excessive hope, and equipment manufacturers will put more effort into a more interesting direction, for example, strive for a larger share of equipment in optical cable factories using metal-tape armored cables as main stream products.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
