[Problems to be Solved by the Invention] A polisher 8 attached to the entrance of the guide holes 3a, 4a of the end face plates 3, 4
As shown in FIG. 5 to FIG.
And is fixedly mounted in a mounting hole 16a formed in a flat plate-shaped bracket 16 to be fixed. In the figure, 16b,
16b is a mounting hole for a bolt 17 for fixing the bracket 16 to the end plates 3 and 4.

When the polisher 8 is fixed as described above, the conductor W comes into contact with the same location on the inner surface of the guide hole of the polisher 8, and as shown in FIG. . As described above, when an extremely worn portion 8b occurs in a part, the conductor passing through the polisher 8 is likely to be disconnected. Therefore, when abrasion occurs, it is necessary to replace the polisher, which is troublesome, increases the cost, and lowers the productivity.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent local abrasion occurring in the polisher and to prevent disconnection of a conductor.

[0008]

In order to achieve the above object, a polisher is rotatably mounted on a bracket via a bearing, and the bracket on which the polisher is mounted is angled so that a conductor is formed on the inner surface of the guide hole of the polisher. The present invention provides a conductor guide device in a twisting machine, characterized in that the polisher is set so as to make point contact with the conductor and the polisher is automatically rotated by the point contact of the conductor.

[0009]

With the above construction, when the conductor is inserted into the guide hole of the polisher, the conductor comes into point contact with the leading end of the guide hole, and the point contacted conductor itself is twisted by the rotation of the rotating shaft and the arc-shaped frame. The polisher is rotated and moved in the winding direction, and the rotational force and the moving force are applied to the polisher. On the other hand, the polisher is rotatably attached to the bracket by a bearing, so that the polisher is automatically driven, that is, without driving. It will rotate. in this way,
Since the polisher automatically rotates upon contact with the conductor, it is possible to prevent the polisher from being locally worn due to the contact with the conductor.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to embodiments shown in the drawings. The configuration of the entire twisting machine using the polisher of the present invention is the configuration shown in FIG. 4, but is not limited to the twisting machine having this configuration. The mounting position of the polisher is the same as that used in FIG. 4 described above, and is installed at the entrance and exit of the guide holes 3a and 4a provided at the connection between the both sides of the arched frame 5 and the rotating shafts 1 and 2. At least, only the polisher 8A that first guides the conductor W may have the structure of the present embodiment.

FIG. 1 shows a first embodiment. In the polisher 20 of the present invention, a flange portion 20b protruding outward is integrally formed at one end of a cylindrical portion 20a as in the prior art. The bracket 21 to which the polisher 20 is attached has a bearing 22 attached to the outer periphery of the polisher attachment hole 21a. The polisher 20 presses and fixes the cylindrical portion 20a inside the inner ring 22a of the bearing 22, and fixes the flange portion 2
0b abuts on the outer end surface of the inner ring 22a to protrude. Thus, the polisher 20 is rotatably attached to the bracket 21 via the bearing 22.

When the polisher 20 attached to the bracket 21 has the conductor W inserted through the guide hole of the cylindrical portion 20a, as shown in FIG. 1, the polisher 20 makes point contact with the inner end of the flange portion 20b. Installed with the inclination set. In order to obtain such an inclination angle, the first of FIG.
In this embodiment, the bracket 21 is a flat plate-shaped bracket similar to the conventional ones shown in FIGS. 6 and 7, and an angle washer 25 is interposed between the bracket 21 and the end face plate 3. The angle washer 25 has a triangular shape in a horizontal section as shown in the figure, and is reduced from the back surface 25a to the front surface 25b.

In the angle washer 25, a bolt hole 25 communicating with bolt holes 21b, 21b formed in the bracket 21 is provided.
c, 25c, and the bracket 21 is bolted to the end face plate 3 with the angle washer 25 interposed.
It is fixed to.

As shown in FIG. 1, the polisher 20 previously mounted on the bracket 21 installed as described above via the bearing 22 is positioned so as to be inclined in the front-rear direction in the horizontal direction. When the polisher 20 is installed with such inclination, the conductor W inserted into the guide hole of the polisher 20 comes into point contact with the inner end of the flange portion at the leading end of the introduction.

With the above structure, the conductor W makes point contact with the guide hole of the polisher 20 at the time of low-speed rotation at the time of starting or the like, and in this state, the conductor W is twisted by the rotation of the arched frame 5 in the direction of arrow X. And at the same time, it is moved in the direction of the arrow Y by the winding operation by the winding reel. Since the rotating force and the moving force of the conductor W act on the polisher 20 that is in point contact with the polisher 20, and the polisher 20 is rotatable with respect to the bracket 21 by the bearing 22, the polisher 20 is in contact with the conductor W. The contact automatically rotates.

As described above, when the polisher 20 comes into contact with the conductor W, the polisher 20 is automatically rotated, so that the portion that comes into contact with the conductor W is not localized, but comes into uniform contact over the entire circumferential direction. Therefore, partial wear is eliminated, the life of the polisher 20 can be extended, and the occurrence of disconnection can be reduced.

FIGS. 2 and 3 show a second embodiment of the present invention, in which the bracket itself is inclined without using the angle washer used in the first embodiment. That is, the bracket 21 'is different from the bracket 21 of the first embodiment with the angle washer 2.
5, and the horizontal section is trapezoidal. A polisher mounting hole 2 formed in the bracket 21 '
1a 'is formed to be inclined with respect to the axial direction of the bolt holes 21b' formed on both sides thereof. The polisher mounting hole 21
A bearing mounting portion is formed on both sides of a ′, and a bearing 22 ′ is mounted to rotatably support the polisher 20. In this manner, the bracket 21 'on which the polisher 20 is rotatably mounted in advance is directly fixed to the end face plate 3 via the bolts 26, 26. Since the operation of the second embodiment is the same as that of the first embodiment, the description will be omitted.

[0018]

As is clear from the above description, according to the present invention, the polisher, which has conventionally been fixed and has caused local wear due to contact with the same place as the conductor, has been removed via the bearing. The polisher that is in contact with the conductor is rotated, and the polisher that is in contact with the conductor is rotated. Contact is made evenly over the entire circumference of the polisher, and local wear can be prevented. Therefore, the disconnection of the conductor, which has frequently occurred due to the occurrence of local wear, can be reduced.

Further, since the polisher is automatically rotated by the contact with the conductor, no means for driving the polisher is required, and the occurrence of local wear of the polisher can be reduced by an extremely simple structure. In addition, the service life of the polisher is prolonged due to the above-mentioned local reduction of abrasion, so that it is possible to reduce costs and improve productivity.
