DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a line for forming a line guard by winding a line guard structure around an outer peripheral surface of a communication cable, a messenger wire, or the like (a long linear body) in an overhead laying of the communication cable. The present invention relates to a device for winding a guard structure.

[0002]

2. Description of the Related Art When laying communication cables overhead,
The line guard structure is wrapped around the telecommunication cable at a portion where the telecommunication cable is fixed, and the telecommunication cable is fixed to a suspension fitting attached to the telegraph pole. The line guard is made by winding several line guard components corresponding to the diameter of the communication cable around the cable jacket without any gaps.The line guard component is composed of multiple steel wires arranged side by side and integrated in a belt shape. It is twisted to the attached state. In a conventional winding device for winding this line guard component around a linear body (communication cable), the line guard component is wound around the linear body from its middle portion to both outer ends. For this reason, it is necessary to start winding in a state where the back surface of the intermediate portion of the line guard component contacts the linear body at the beginning of winding.

FIG. 4 (a) shows a wrapping device for a line guard structure, which has not been disclosed yet, and which was previously filed by the present applicant. As shown in the figure, the winding device includes a pair of rotating bodies 62, 62 rotatably attached to left and right side plates 61a, 61a of a frame 61 in a face-to-face state. Are wound around three line guard members 63, and a long linear member 64 is disposed at the axis thereof. Then, in this state, the line guard constituting body 63 is wound around the linear body 64 by rotating the two rotating bodies 62 in opposite directions. For this reason,
The two rotating bodies 62, 62 are the left and right side plates 61 of the frame 61.
a and 61a are synchronously rotated in opposite directions by drive motors 65 attached respectively.

On the other hand, a winding adjustment mechanism 71 as shown in FIG. 4B is provided at an intermediate portion of the rotating body 62 in the facing direction. The winding adjustment mechanism 71 includes a sub-frame 72
Is provided with three gripping means 73, 73, 73, and these gripping means 73, 73, 73
2 and is slidably mounted in a guide groove 74 formed therein. The guide groove 74 extends in three directions from the position where the linear body 64 is provided, and the main body 75 of the gripping means 73 is slidably engaged on both sides thereof. The sliding movement includes a setting position of the line guard component 63 where the gripping means 73 is located at the outer end of the guide groove 74 and a line guard configuration where the gripping means 73 comes close to the linear body 64 and abuts the stopper 76. This is performed between the winding start position of the body 63. Also, the main body 7
A gripping member 78 is attached to the inner end of 5 via a leaf spring 77 so that the intermediate portion of the line guard structure 63 can be gripped by the gripping member 78 using the spring force of the leaf spring 77.

[0005] In the drawing, reference numeral 79 denotes a slit, and the linear body 64 is rotated by the rotating body 62 through the slit 79.
Set on the same axis. Reference numeral 66 in the figure denotes a guide rod. The guide rod 66 has a function of adjusting the facing distance between the two rotating bodies 62 at both ends and a function of fixing the sub-frame 72.

[0006] In the conventional winding apparatus having the above-described structure, the linear member 64 is set, and at the same time, the linear member 64 is set in parallel with the linear member.
The line guard components 63 are set (see FIG. 3). In this case, both ends of the line guard structure 63 are set on the rotating bodies 62, respectively, and the intermediate part is set on the gripping member 78 of the gripping means 73. Next, the two rotating bodies 62 are rotated in opposite directions by the drive motor 65, so that the line guard structure 63 is uniformly wound around the linear body 64. At this time, the line guard component 63 set in a state parallel to the linear member 64 is displaced obliquely so as to be twisted as a whole, and the intermediate portion thereof is firstly moved to the linear member 6.
4 and the winding is started. With this oblique displacement, the gripping means 73 is slid toward the linear body 64 and finally hits the stopper 76 to restrict its movement. Then, the line guard structure 63 is moved to the gripping member 78.
And is wound around the long linear body 64 while maintaining a desired posture.

[0007]

In the above conventional example, the gripping member 78 gripping the intermediate portion of the line guard structure 63 is used.
However, it has a structure that approaches the linear body 64 while sliding on the sub-frame 72. However, the wrapping device itself is mainly used outdoors, and there is a possibility that dust or dirt may adhere to the sliding portion and the sliding may not be performed smoothly. On the other hand, the line guard component 63 itself is also coated with a non-slip material such as aluminum oxide so that it does not slip between the linear member 64 and the linear member 64 after being attached. There was a problem that sliding was not performed smoothly. If the gripping member 78 does not slide properly,
Before the line guard component 63 approaches the linear member 64 sufficiently, the line guard component 63 comes off the gripping member 78, so that an appropriate posture at the beginning of winding cannot be maintained and a winding error occurs.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks, and it is an object of the present invention to provide an apparatus for winding a line guard component which appropriately holds a winding start posture of the line guard component on a linear body. For that purpose.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a line guard structure having a predetermined number of twisted lines between a pair of rotating bodies attached to a frame facing each other. Along with the suspension, a linear body around which the line guard structure is wound is disposed around the axis of the rotating body, and the pair of rotating bodies are rotated in opposite directions to wind the line guard structure around the linear body. At this time, in a line guard component winding device configured to guide the line guard component from the set position to the winding start position while holding the intermediate portion of the line guard component in a desired posture by the winding adjustment mechanism. The winding adjustment mechanism includes a sub-frame provided at an intermediate portion of the rotating body in the facing direction, and gripping means attached to the sub-frame and holding the intermediate portion of each line guard component. The means includes a gripping member that grips the intermediate portion of the line guard structure in a desired posture, and the gripping member is rotated to the linear body side in response to a stress toward the linear body at the end of the line guard structure accompanying the winding. It has a moving member to move, and a stopper for stopping the movement of the gripping member near the linear body.

[0010]

The line guard structure is gripped at a desired position by a gripping member at the intermediate portion thereof, and is pivotally moved toward the linear body by the moving member. , Gradually approaching the linear body while rotating. When the gripping member approaches the linear body to a desired position, the gripping member abuts against the stopper and stops its rotation. on the other hand,
Since the line guard component is subjected to a rotational force to further approach the linear member, the line guard component is automatically released from the gripping member in the vicinity of the linear member and has a desired posture in the linear member. And the winding is started. In this case, the movement of the gripping member is not a sliding movement but a rotating movement. The rotating shaft for this rotating movement can be provided at a position distant from the linear body, and the rotating shaft can have a structure in which the exposed portion is extremely small.

[0011]

And a power transmission shaft 8 for transmitting power to the motor. Drive motor 7
Is controlled by a control panel 6, and its output is transmitted to a power transmission shaft 8 via a timing belt 9, where it is branched in two directions and output to both rotating bodies 5 and 5. That is, the power transmission shaft 8 is connected to the input shaft 1 to which the power of the drive motor 7 is input.
0, and an output shaft 11 that outputs the power to each rotating body 5. The power of the drive motor 7 is input to an intermediate portion of the input shaft 10 and branched in two directions. One output shaft 11 is connected to the input shaft 10 via a flexible joint 12 and is rotated in the same direction as the drive motor 7, and the other output shaft 11 is connected to the input shaft 10 via a bevel gear train 13. Then, it is rotated in the opposite direction to the drive motor 7. Therefore, both output shafts 1
The rotating bodies 5, 5 to which power is respectively transmitted from 1, 1 and 11 are rotated in mutually opposite directions.

On the other hand, each rotating body 5 comprises a main body 14 fixed to the side plate 3 of the frame 1, a rotating cylinder 15 extending from the main body 14 in a facing direction, and a holder 16 detachably provided on the rotating cylinder 15. ing. A gear 17 is attached to the outer peripheral surface of the rotating cylinder 15, and a pair of upper and lower guide gears 18 mesh with the gear 17 so as to surround the gear 17.
One of the upper guide gears 18 also serves as an idle gear, to which power from the output shaft 11 is transmitted via a timing belt 19.

A facing plate 20 is provided on the entire surface of the holder 16.
Are fixed, and holding means 21 for holding the line guard structure A is attached to the facing plate 20. A substantially hexagonal (see FIG. 2) support plate 22 is fixed to an intermediate outer peripheral portion of each holder 16. The left and right support plates 22, 22 are connected by four adjustment rods 23, 23, 23, 23 disposed at the four corners thereof, and the respective connection portions are tightened and fixed by double nuts 24. I have. That is, by appropriately tightening and adjusting the double nut 24, the distance between the two facing plates 20 can be freely adjusted via the support plate 22. In response to this adjustment operation, the facing plate 20 is slidable within a predetermined range with respect to the rotary cylinder 15. Therefore, the distance between the two facing plates 20, 20, that is, the distance between the corresponding holding means 21 is adjusted according to the length of the line guard structure A, so that the line guard structure A can be appropriately held. .

On the other hand, a winding adjusting mechanism 41 is provided at an intermediate portion of the adjusting rod 23 so as to be supported by the four adjusting rods 23. The winding adjustment mechanism 41 includes a gripping means 42 facing the elongated linear body B located at the center from three directions,
42, 42 are provided on the sub-frame 43, and the intermediate portion which is the winding start portion of the line guard structure A is gripped by the gripping means 42 so that the line guard structure A is started when winding is started. A can keep an appropriate posture.

Next, with reference to FIG.
1 will be described in detail. The winding adjustment mechanism 41 grips the intermediate portion of the line guard structure A and moves it from the set position to the winding start position while maintaining a desired posture. Two winding adjustment mechanisms are provided on one surface of the sub-frame 43. , And a structure in which a total of three gripping means 42, 42, 42 are attached to the other surface. The sub-frame 43 is supported and fixed by the adjustment rod 23 penetrating the four corners,
At the center thereof, there is provided an opening 44 formed wide in three directions from the position where the elongated linear body B is set, and a slit 45 formed so as to communicate the opening 44 with the outside. . The opening 44 is provided with each of the holding means 42 as described later.
The slit 45 is used as a space into which the elongated linear body B is inserted.

Each of the gripping means 42 includes a rotating arm 51 which is a movable member rotatably attached to a cantilevered support shaft 52 extending from the sub-frame 43, and a gripper attached to the tip of the rotating arm 51. The member 52 and the rotating arm 51
A stopper pin 54 that abuts the holding member 52 to restrict rotation of the holding member 52 toward the long linear body B, and a coil that urges the holding member 53 to the home position side opposite to the long linear body B side. And a spring 55.

The rotating arm 51 includes a main body 51a attached to a support shaft 52, and an arm 5 extending from the main body 51a.
1b, a gripping member 53 is provided at the tip of the arm portion 51b.
Is attached. The rotating arm 51 is rotated around the support shaft 52 in the radial direction of the sub-frame 43, that is, toward the set elongated linear body B. This rotation is regulated by a stopper pin 54 erected on the sub-frame 43 near the long linear body B.
For this reason, the rotation arm 51 has the stopper pin 5 inside.
In the position 4, on the outside, the holding member 53 is attached to the outer end of the opening 44.
The rotation of each is restricted at the position where the abutment. The pivot arm 51 is urged outward, that is, toward the home position, by a coil spring 55 provided between the pivot arm 51 and a pin 56 erected on the peripheral edge of the subframe 43. Therefore, as will be described later, as the winding of the line guard structure A progresses, the turning arm 51 gradually turns in the direction of the long linear body B, and is turned by the stopper pin 54 immediately before completion of the winding. The movement is stopped, and at the same time the line guard component A comes off, it is returned to the home position by the urging force of the coil spring 55.

The gripping member 53 is attached at its base to the arm portion 51b of the rotating arm 51, and has a pair of handling blocks 5 at its distal end via a leaf spring 57 having a U-shaped cross section.
8, 58 are attached. The two handling blocks 58, 58 are fixed to the legs of the leaf spring 57, respectively, so that the leaf spring 57 can be expanded so that the line guard component A can be sandwiched and gripped by the two handling blocks 58, 58. ing. Therefore, the line guard component A is gripped by the gripping member 53 at the set position, and is moved to the vicinity of the elongated linear member B, that is, immediately before the winding start position while maintaining the desired posture. When the movement is restricted by the above, the wrapping force exceeds the gripping force of the gripping member 53, and the line guard component A comes off the gripping member 53.

Next, the winding operation of the line guard structure A by the winding device will be described with reference to FIG. After adjusting the facing distance between the facing plates 20 facing each other by adjusting the double nuts 24 provided at both ends of the adjusting rod 23 in accordance with the length of the line guard structure A, 3
The line guard components A are set on the corresponding holding members 21 so as to be parallel to each other. At the same time, the intermediate portion of each line guard structure A is also wound around the winding adjustment mechanism 4.
It is set on the first holding means 42. In this state, the winding device itself is moved to a position where the long linear body B such as a communication cable is wound, and the winding device is further positioned so that the long linear body B is coaxial with the rotating body 5. Move and adjust (Fig. 5
(A)).

Next, the two rotating bodies 5 and 5 are rotated in opposite directions to start winding the line guard structure A. At this time, each line guard component A is displaced obliquely from the parallel state with respect to the long linear body B, contacts the long linear body B at an intermediate portion thereof, and from this portion to both outer end portions. Winding starts toward. Therefore, the holding member 53 of the holding means 42
As the intermediate part of the line guard structure A approaches the long linear body B, the line guard construct A approaches the long linear body B while holding the intermediate part. In this case, immediately before the intermediate portion of the line guard component A comes into contact with the long linear body B, the movement of the gripping member 53 is restricted by the stopper pin 54, and here the gripping force of the gripping member 53 is less than the winding force. As a result, the line guard component A comes off the gripping member 53 while maintaining the desired posture. That is, the back surface side of the line guard structure A is in contact with the long linear body B, and the winding is appropriately started (FIG. 5).
(B)).

Next, when the line guard structure A is wound from the intermediate portion to both outer ends, both outer ends of the line guard structure A face the long linear body B due to the twisting habit. (FIG. 5 (c)).

When the winding of the line guard structure A enters the final stage, both ends of the line guard structure A that is finally left gradually approach the long linear body B, and finally the line is moved from the holding means 21 to the line. Both ends of the guard structure A come off and are instantaneously wound around the long linear body B (FIG. 5 (d)).

As described above, in the present embodiment, the holding member 53 holding the line guard structure A in an appropriate posture is attached to the support shaft 5.
2, the line guard component A is guided from the set position to the winding start position in accordance with the movement of the line guard component A. It can be started to be wound around the shank B. In this case, since the support shaft 52, which is a rotating portion, is concealed in the bearing of the rotating arm 51, dust and dirt hardly enter the rotating portion. Since the positions of the shafts 52 are far apart, the slip stopper applied to the line guard structure A is less likely to adhere to the support shaft 52. Therefore,
The rotation of the gripping member 53 is always performed smoothly, and a winding mistake at the start of winding is prevented, so that the line guard component A can be wound around the long linear body B extremely well.

In this embodiment, a description has been given of a winding device using three line guard structures A. However, a sub-frame 43 to which various numbers of gripping means 42 are attached is prepared, and is appropriately replaced. By doing so, it is needless to say that the winding device can handle a different number of line guard components A.

[0027]

As described above, according to the present invention, since the holding member for holding the intermediate portion of the line guard structure is turned by the moving member, this turning movement is achieved. The rotating shaft can be provided at a position distant from the linear body, and a structure in which the exposed portion is extremely reduced can be provided. Therefore, it is possible to structurally prevent adhesion of dust and dirt, and it is possible to guide the line guard component from the set position to the winding start position without difficulty while maintaining the line guard component in a desired posture.
