DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus used for winding a cable and a method for winding a cable using the apparatus.

[0002]

2. Description of the Related Art Conventionally, as a cable winding device used when winding a cable around a cable drum,
There is one shown in FIG. This cable winding device 50
Is configured to wind the cable 100 around the cable drum 101 rotated by the drum rotating unit 52 while guiding the cable 100 to the cable drum 101 by the cable guide unit 51. The cable guide portion 51 includes a guide roller cylinder 53 arranged in a well shape, and the cable 100 is inserted into the cable guide portion 51 to guide the cable 100 to the cable drum 101.

[0003]

The conventional cable winding device 50 has the following problems. That is, the cable guide portion 51 has a relatively large structure because the guide roller cylinder 53 is formed in a well shape. For this reason, the cable guide portion 51 cannot be disposed on the drum inner side with respect to the flange 102 of the cable drum 101, and must be disposed at a position separated from the winding point (indicated by A in the drawing) of the cable drum 101. Did not. Therefore, as a result of the cable 100 floating between the cable guide portion 51 and the winding point A, the positioning of the cable 100 at the winding point A becomes insufficient, and the cable 100 rides on the wound cable 100, This has caused cable winding disturbance such that an unnecessarily large gap is formed between the cable 100 and the wound cable 100.

Accordingly, an object of the present invention is to provide a cable winding device capable of winding a cable without causing winding disturbance.

In order to achieve the above object, according to the present invention, there is provided a cable for guiding a cable to a peripheral surface of a cable drum while moving relative to the cable drum rotated around the axis in parallel with the axis. A cable guide portion retreating transport mechanism for retreating and transporting the cable guide portion to the outside of the cable drum along the radial direction of the cable drum as the cable winding proceeds. The portion is disposed on the tangent of the cable drum, and the tip of the portion extends close to the contact point of the tangential cable drum .
The cable retraction direction of the cable guide
From the direction perpendicular to the tangent at the tip of the
It is set in the direction slightly inclined to the cable guide part side,
From the above, a cable winding device was constructed.

[0006]

According to the above construction, the cable guide portion is arranged on the tangent of the cable drum, and the tip of the cable guide extends to the vicinity of the drum contact of the tangent to the cable drum. And the cable guide portion are close to each other, so that the cable can be reliably positioned at the winding point.

[0007] When the cable guide portion is disposed close to the cable drum in this manner, as the cable winding progresses, the cable guide portion abuts on the cable drum that is thickened by the wound cable, which hinders winding. However, as the winding progresses, the cable guide retracting / conveying mechanism retracts and transports the cable guide toward the outside of the cable drum. I will not touch you.

And a small-diameter portion 40b that supports the support wire 152. A swing air cylinder 29 is provided between the end of the support shaft 24b and the bracket 16, and the cable guide portion 12 can swing about the support shaft 24b by expansion and contraction of the swing air cylinder 29. It has become. Further, the distal end of the cable guide portion 12 is cut off obliquely so as not to abut on the drum peripheral surface 101a located nearby. Further, the width H of the cable guide section 12 is smaller than the width h of the self-supporting cable 150 guided by the guide roller groups 27 and 28, and the side end (one side) of the cable guide section 12 during the cable guide. The end is constituted by the side surface of the roller 40, and the other side end is constituted by the side surface of the upper guide member 25).

The cable winding device 1 has a traverse mechanism 30. The traverse mechanism 30 includes a traverse motor 31, a coupling 32, a speed reducer 33, and a gear unit 34 provided on the slide base 6, and a ball screw 35 disposed on the fixed base 4 and meshing with the gear unit 34. The rotation drive of the traverse motor 31 transmitted to the gear unit 34 via the coupling 32 and the speed reducer 33 is changed to a linear movement drive by meshing the gear unit 34 with the ball screw 35, and the linear drive force is used. The slide table 6 and, consequently, the cable guide section 12 are moved along the axial direction of the cable drum 101.

Next, the cable winding operation by the cable winding device 1 will be described. First, the drum elevating motor 9 is driven to lower the elevating body 8 to the drum mounting position, and the cable drum 101 is mounted between the drum holding members 10 at this position. Cable drum 101
Then, the drum lifting motor 9 is driven to raise the cable drum 101 to the winding position. Then, the guide roller groups 27 and 28 of the cable guide section 12
The self-supporting cable 150 is inserted between them. At this time, the constricted portion 153 of the self-supporting cable 150 is formed by the large diameter portion 40a of each of the rollers 40,.
The supporting wire 152 is supported by the small diameter portion 40b, and the self-supporting cable 1 is supported by the guide roller groups 27 and 28.
The 50 support lines 152 are sandwiched. This is the support line 152
Is more rigid than the cable main body 151, and the guide of the support wire 152 can be wound up without being disturbed.

After the self-supporting cable 150 is inserted into the cable guide section 12, the end of the cable 150 is fixed to the cable drum 101, and in this state, the drum rotation motor 11 is driven to rotate the cable drum 101 so that the self-supporting cable 150 is rotated. The cable 150 is wound around the cable drum 101. The traverse mechanism 30 is driven at the same time as the cable is wound, and the slide table 6 is slowly reciprocated at a predetermined transfer pitch, thereby gradually moving the cable drum 101 along its axial direction. Connect the supporting cable 150 to the drum peripheral surface 101a.
Take up without gaps along.

At this time, since the distal end of the cable guide portion 12 extends to near the winding point A, the cable guide portion 12 and the winding point A are hardly separated. Therefore, the position of the winding point does not become unstable due to the floating of the self-supporting cable 150 between the cable guide portion 12 and the winding point A, and the self-supporting cable 150 is guided by the cable guiding portion 12. It is wound around the cable drum 101 without being disturbed.

When the cable winding device 1 is configured as described above, the cable winding progresses, and when the self-supporting cable 150 is guided to the vicinity of the flange 102 by the cable guide portion 12, the cable guide portion 12
, The self-supporting cable 150 may not be wound around the drum peripheral surface 101a near the flange 102. However, in this cable winding device 1,
As described above, the width H of the cable guide portion 12 is made smaller than the width h of the self-supporting cable 150 being sandwiched, so that the side end of the cable guide portion 12 is not located outside the side end of the self-supporting cable 150. I have to. Therefore, the self-supporting type cable 150 can be guided to a position where it comes into contact with the flange 102, and can be efficiently used and wound up from end to end of the cable drum peripheral surface 101a.

As the winding of the cable progresses in this manner, the cable drum 101 is thickened by the wound self-supporting cable 150. Therefore, in parallel with the winding of the cable, the cable guide section retracting / transporting mechanism 14 is driven to convey the cable guide section 12 obliquely upward, so that the cable guide section 12 abuts on the thickened cable drum peripheral surface 101a. I try not to. The evacuation conveyance at this time is not straight upward but diagonally upward (slightly more than the direction orthogonal to the tangent α).
(The direction inclined toward the bull guide section 12) . This is due to the following reasons.

That is, as shown in FIG. 4, the peripheral surface of the drum 101a (indicated by a solid line in the drawing) 101a at the beginning of winding has a small curvature because it is not thickened. It can be placed close to the taking point A. However, as the winding progresses and the cable drum 101 becomes thicker, the diameter of the cable drum peripheral surface (indicated by a two-dot chain line in the figure) 101a is increased by the wound self-supporting cable 150. However, the curvature becomes large, and if the cable guide portion 12 is moved straight upward, the cable guide portion 12 abuts on the drum peripheral surface 101a and cannot be wound.
Therefore, it is necessary to retreat and transport the cable guide section 12 also in the lateral direction. Therefore, this cable winding device 1
In this configuration, the cable guide section 12 is conveyed obliquely upward, so that both vertical and horizontal retraction conveyance are performed at one time. According to experiments by the inventor of the present application, it has been found that if the conveying direction of the cable guide portion 12 is inclined by about 15 degrees from the vertical direction toward the side close to the tangent line α, even if the winding proceeds, the cable guide portion 12 does not hit the cable drum peripheral surface 101a. The cable guide portion 12 can be evacuated and conveyed without contact and without being too far from the cable drum 101.

The cable winding device 1 of the present embodiment
By adjusting the amount of expansion and contraction of the holding cylinder 26, the cable holding force of the cable guide portion 12 can be adjusted. Further, the distal end of the cable guide portion 12 is swung up and down by expanding and contracting the swinging cylinder 29, and this swinging can correct a slight turbulence such as riding on the cable.

Further, in the above embodiment, the present invention is embodied in the cable winding device for winding the self-supporting type cable 150. However, in the cable winding device for winding an ordinary cable having a circular cross section, the present invention is applied. Needless to say, the present invention can be implemented.

[0021]

As described above, according to the present invention, the leading end of the cable guide portion is extended to the vicinity of the tangential line of the cable drum, so that the winding point of the cable drum and the cable guide portion are close to each other. As a result, the positioning of the cable at the winding point was assured, and the winding was hardly disturbed. In particular, make sure that
Not diagonally upward, but diagonally upward (directly
(A direction slightly inclined to the cable guide side from the crossing direction)
By setting the cable guide to the drum peripheral surface
Cable drum winding point
Cable and cable guide as close as possible.
It has become possible.

If the width of the cable guide portion is made smaller than the width of the cable being guided so that the side end of the cable guide portion is not located outside the side end of the cable, the cable comes into contact with the flange of the cable drum. The cable drum can be guided to the position, and can be used and wound efficiently without waste from end to end of the peripheral surface of the cable drum.

Further, when winding the self-supporting cable, guiding the support wire of the self-supporting cable by the cable guide portion can further reduce the turbulence.
