Heat-treated by heat treatment in a state.

Then, the plated copper wire is guided through the plating bath in which the plating solution is stored by guiding the heat-treated copper wire, and the cooling solution is cooled through the cooling bath, and then the copper plated copper wire is wound on the winding bobbin by a winding device. do.

However, in the conventional multi-stage rolling apparatus, since the cylindrical boss on which the rolled flat line is wound and the H bobbins formed at right angles of the supporting portions provided on both sides are rotated at a constant speed, the circumferential distance of the winding portion after the initial stage of the flat line and after some progress is achieved. Since there is a problem that the winding speed of the flat line is changed.

In addition, since there is no tension sensing means for controlling the first heat treatment roller and the second heat treatment roller, the movement speed of the copper wire passing through the first rolling part and the second rolling part is the movement speed of the copper wire passing through the first heat treatment part and the second heat treatment part. There was a problem that the difference between the thickness and width formed unevenly during the heat treatment of the copper wire.

The conventional method as described above is significantly reduced workability and productivity has an impact on the production cost.

As shown in FIG. 8, after measuring the displacement of the cable wire 101 by the third displacement sensor 82 in the tertiary tension adjusting and measuring device 80 (S10), the controller transmits the displacement to the control unit (S20). ). Subsequently, when it is determined that the measured displacement is smaller than the first displacement preset in the controller (S30), the rotational speed of the servomotor 97 is converted to the calculated rotational speed corresponding to the calculated displacement (S40). 97 is accelerated controlled (S50).

Herein, it may be determined that the tension is reduced as the measured displacement increases, and in order to recover the reduced tension to a constant level, the controller is controlled by the controller to slow down the rotation speed of the servo motor 97. Do. That is, when the tension applied to the cable wire 101 is reduced, the fall amount of the third buffer roller 81 increases due to gravity, so that the displacement between the third buffer roller 81 and the third displacement sensor 82 is reduced.

Velocity means the rotational speed that is experimentally calculated such an inverse relationship to match the formulated table data.

Herein, it may be determined that the tension is increased as the measured displacement is increased, and in order to recover the reduced tension to a constant level, the controller is controlled by the controller to accelerate the rotation speed of the stepping motor 96. Do.

In this case, the second displacement preset in the controller is measured when the cable wire 101 wound on the inclined bobbin 91 has a minimum tension to prevent the cable wire 101 from being twisted at both ends of the expansion type inclined support part 99.

That is, when it is determined that the measured displacement is smaller than the first displacement and the second displacement preset by the controller when the first displacement and the second displacement are detected, the servo motor 97 accelerates. And the stepping motor 96 is decelerated.

Here, the stepping motor 96 may be controlled to be gradually accelerated according to the degree that the rotational speed of the servo motor 97 is accelerated and the tension is continuously increased after a certain point of time.

Through this, the servo motor 97 and the stepping motor 96 by performing the double safety control through the control unit by minimizing the twisting of the cable wire 101 wound around the inclined bobbin 91 product The defective rate of is reduced and there is an effect to improve the productivity.

And control the first rolling roller 103 and the first heat treatment roller 105 by transmitting the displacement measured by the secondary tension control and measuring device 50 to the controller.

And, by transmitting the displacement measured in the third tension control and measuring device 80 to the control unit to control the second rolling roller 103 and the first heat treatment roller 105 and the winding unit 90 of The rotation of the servo motor 97 and the horizontal motion of the stepping motor 96 are interlocked with each other, and the cable wire 101 transferred from the winding guide device 98 is wound around the inclined bobbin 91. When it is possible to control the twisting phenomenon due to the sag of the cable wire 101 has the effect of improving the productivity.

In addition, the servo motor 97 connected to the rotating shaft portion of the inclined bobbin 91 minimizes an error angle of the reduction gear to give an equal tension to the feed roller to have the same feed amount left and right, and the stepping motor 96 ) Is proportional to the number of input signals and the rotational angle of the stepping motor 96, so that the cable wire is wound around the inclined bobbin 91 so that the inclined bobbin 91 is horizontally moved so that the winding is aligned. Economics can be improved by reducing

As described above, the present invention is not limited to the above-described embodiments, and variations and modifications may be made by those skilled in the art without departing from the scope of the present invention. And such modifications are within the scope of the present invention.
