Abstract

PURPOSE:To attain space-saving by arranging plural vertical rotary rolls so that a circular arc having a large bending radius is formed on a winding material when the winding material is fed crosswise by a vertical rotary roll in a front position of the take-up drum. CONSTITUTION:A cross feed device 1 for the winding material feeds the winding material crosswise and the take-up drum 17 coils the winding material A. Plural rotary rolls 3, 5 are equipped freely rotatably on the cross feed device 1 for the winding material. Each rotary roll 3, 5 is arranged so that the circular arc having a large bending radius is formed. Since a bend generated on the winding material A is limited by a curvature of the circular arc formed by the rotary rolls 3, 5 even though the cross feed device l and a fixed roll 20 are approached to each other, resistance for bending does not increse and instability for continuous bending, too, is not generated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved construction of a traverse device for winding a winding material in a winding device for a highly rigid rod material.

[0002]

2. Description of the Related Art In a conventional rod winding device, as shown in FIG. 5, a winding material transverse feeding device 30 is provided in front of a winding drum 32. This winding material lateral feeding device 30 is composed of a pair of vertical rolls 31, 31 facing each other, and a single roll 31 is provided for the winding material A between the winding drum 32 and the rolls 34, 34 on the fixed roll 33. By making it work, it is possible to laterally feed and wind the winding material A in line on the winding drum 32. In addition, A'indicates a state in which the winding material A is wound.

[0003]

In the above-mentioned conventional apparatus, when the winding material transverse feeding device 30 laterally feeds, as shown in FIG. 6, due to the rigidity of the winding material, it is bent with a diameter larger than the diameter of the rotating roll 31. It is preferable to be in a state. However, in order to improve the winding condition of the winding material A on the winding drum 32, when the tension on the winding material A is increased, as shown in FIG. A bend 35 occurs in the winding material A.

As described above, when the roll is bent along the outer surface of the rotating roll 31 or is bent with a small bending radius, the reciprocal of the bending radius is proportional to the bending resistance, and therefore, the winding material A has an extremely large bending resistance. It will be. Further, continuous bending by the rotating roll 31 becomes unstable in a range where the outer diameter of the rotating roll 31 is not close and the bending radius is small.

Conventionally, in order to prevent the above-mentioned increase in bending resistance and destabilization of continuous bending, the distance between the winding material transverse feeding device 30 and the fixed roll 33 is increased so that the material is laterally fed to the winding material. A method was adopted in which the bending angle of the roll was reduced, or, in the case of instability of continuous bending, a large tension was applied to the wound material so that the roll was bent completely along the outer surface of the rotary roll 31.

However, in this case, a wide installation space is required for the entire equipment including the winding device, and the equipment becomes large.

Therefore, the present invention does not cause an increase in the bending resistance of the winding material at the time of transverse feeding and the instability of continuous bending with respect to the winding material. It is an object of the present invention to provide a winding material traverse device for a rod material winding device, which can save space by shortening the distance between them and can save energy.

[0008]

In order to achieve the above-mentioned object, the present invention is configured as follows for a winding material lateral feeding device for a rod material winding device. That is, in a rod material winding device for winding a rod-shaped winding material on a winding drum, a plurality of vertical rotating rolls are laterally fed by their outer surfaces to a position in front of the winding drum. Arranged so as to form an arc with a bending radius larger than the cross-sectional radius of the rotating roll on the winding material, and provided continuously with the transverse feed function part in a state where the tangential direction of the arc matches the winding direction of this winding material. It is characterized by being formed.

In the above-described rod material winding device according to the present invention, various rod materials made of iron, copper, aluminum, etc. can be taken up as a winding object. Therefore, the bending radius of the above-mentioned arc in the winding material transverse feeding device according to the present invention also differs depending on the material type of the target winding material. For example, when the winding material is a copper material, the bending radius is Each rotating roll can be arranged in an arc shape of about 10 m.

Further, in the rod material winding device according to the present invention, the fixed roll corresponding to the winding material transverse feeding device does not cause bending of the winding material with a small radius,
The conventional one can be used as it is. In addition, in order to prevent bending of the winding material on the fixed roll side with a small radius, various configurations such as a roll arranged in an arc shape similar to the winding material transverse feeding device according to the present invention may be adopted. it can.

Further, the lateral feed function section can be constituted by, for example, a ball screw unit.

[0012]

In the present invention, the following actions occur. According to the operation of the transverse feed function section, which is composed of a plurality of rotating rolls arranged in an arc position, the winding process is performed between the winding drum and the fixed roll in the rod winding device. It is pressed against the winding material inside.

At this time, the corresponding part of the winding material is bent along the arcuate surface formed by the respective rotating rolls. However, this bending is restricted to be equal to or larger than the bending radius of the above-mentioned circular arc, so that the winding material does not bend with a small radius. Therefore, even if the tension on the winding material increases, the bending resistance of this winding material portion is kept below a certain value, and the bending radius for the winding material does not reach the unstable region, so that continuous bending can be stabilized. it can.

Further, since the tangential direction of the arc formed by each of the rotating rolls is in the state of being coincident with the winding direction of the winding material, the portion of the winding material fed laterally is at the winding position on the winding drum. The winding material is sequentially wound on the winding drum in an aligned state.
