A protective sheet 20 is mounted on this moving table 4 where the upper end part is mounted, and the lower end part is extended downward so as to hold the wire material 100 delivered from a pair of traverse guide rolls 2, 2 from both sides, and enters inside of both flanges 52, 52 of the winding drum 50 and inward by the prescribed length (L).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for traversing a wire rod in the width direction of the winding drum when the wire rod is wound on the winding drum. In particular, the traverse device of the present invention is a unit. It can be used effectively when winding a wire without external protection such as a stranded wire without damaging it.

[0002]

2. Description of the Related Art Conventionally, when winding a wire rod 100 on a winding drum 50, as shown schematically in FIG. 3, the winding drum 50 is rotated to wind the continuously supplied wire rod 100 at the same time. This wire rod 100 is sandwiched by a pair of traverse guide rolls 2 and 2 of the traverse device 1, and is guided, that is, traversed at a constant speed in the width direction of the winding drum 50, and is automatically wound. .

At this time, the traverse width of the traverse device 1, that is, the left and right turn positions of the traverse guide roll pairs 2 and 2 differ depending on the size of the winding drum 50.
Therefore, it is adjusted according to the size of the winding drum 50 used.

Further, in order to keep the winding condition of the wire 100 in a good condition, the traverse width is set to a position just near the brim 52 of the winding drum 50, and further, the traverse turn is stopped for about 2 seconds. ing.

[0005]

However, according to the structure of the conventional traverse apparatus 1 described above, the wire rod 100 is
Depending on the shape of the winding drum 50 or the mounting state,
At the time of the traverse turn, the flange 52 of the winding drum 50 may be rubbed, and the wire 100 may be scratched. In particular, such a scratch was frequently found in a wire rod such as a unit stranded wire which has no external protection.

Therefore, it is an object of the present invention to prevent the wire rod from being scratched by rubbing against the flange of the winding drum at the time of traverse turn, and in particular, there is no external protection such as a unit twisted wire. It is an object of the present invention to provide a traverse device capable of eliminating such scratches even when winding a wire rod.

[0007]

The above object is achieved by the traverse device according to the present invention. In summary, the present invention relates to a traverse guide roll pair for sandwiching and feeding a continuously supplied wire rod to a winding drum, and a traverse guide roll pair for carrying the reciprocating motion in the width direction of the winding drum. A moving table and an upper end portion are attached to the moving table, and a lower end portion extends downward so as to sandwich the wire rod fed from the traverse guide roll pair from both sides,
A traverse device for a wire rod is provided, which has a protective sheet inside both of the flanges of the winding drum and inwardly extending a predetermined length.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The traverse device according to the present invention will be described below in more detail with reference to the drawings.

1 and 2 show a traverse device 1 of the present invention.
One example of is shown. In the present embodiment, the traverse device 1 has traverse guide roll pairs 2 and 2 for sandwiching the continuously supplied wire 100 and guiding it to the winding drum 50, as in the conventional case. The traverse guide roll pairs 2 and 2 are arranged vertically in this embodiment, and the upper ends thereof are rotatably carried by the moving table 4. The moving base 4 is slidably attached via a bearing 8 to a base 6 arranged so as to extend in the axial direction (that is, the width direction) of the winding drum 50, and is attached to a driving means (not shown). Thus, the winding drum 50 can be reciprocated in the width direction.

According to the present invention, a protective sheet 20 is further attached to the movable table 4. This protection sheet 2
In the present embodiment, 0 is composed of two sheets, the upper end of which is fixed to the movable table 4 via a fixture 22. The lower end of the protective sheet 20 has a collar 52 of the winding drum 50,
It is in a state of being inwardly of the inner side of 52 and being inwardly of a predetermined length (L).

According to the traverse device 1 of the present invention having the above-described structure, the wire rod 100, which is sandwiched by the traverse guide roll pairs 2 and 2 and is guided to the winding drum 50, is wound between the protective sheets 20. It is wound around the drum 50. Therefore, during the traverse turn, the wire rod 100 does not come into direct contact with the flange 52 of the winding drum 50. Therefore, even if the wire rod 100 is stopped for about 2 seconds during the traverse turn, the wire rod 100 will not be contacted. No scratches from

As the protective sheet 20 used for such a purpose, any one can be used.
Felt is suitable, and its thickness is selected so as not to affect the winding state of the wire. For example, when the wire rod 100 is a unit stranded wire, it is preferably about 4 mm. Examples of such felt include Needle Felt # 6000 (trade name).

[0013]

As described above, the wire rod traverse device according to the present invention extends downward so that the wire rod fed from the traverse guide roll pair is sandwiched from both sides, and both of the winding drums are wound. Since the protective sheet is arranged inside the tsuba and inward for a specified length, the wire rod is scratched by the rubbing of the take-up drum's tsuba during the traverse turn. It is possible to prevent the occurrence of such scratches, especially when winding a wire rod without external protection such as a unit twisted wire.
