The wire rod is cut after being stretched, the wire rod of a required length is wound around the empty reel, and then the winding machine with the empty reel set is placed on a support table.

(E) Embodiment As shown in FIGS. 1 to 5, a plurality of enamelled copper wires (hereinafter referred to as wires W) sent out from a baking furnace are each hung on a capstan 1 and guided by a traverser 2. The winder is then wound on a reel 21 of a winder 20 supported by a winder support base 10.

At the front lower part of the winding machine support base 10, a main rail 30 is laid in parallel to the front surface of the base 10, and wheels 32 provided on the lower side of the transport vehicle 31 are placed on the main rail 30 so that the winding machine can be moved freely. support.

The transport vehicle 31 is equipped with a turntable 33 on the upper part, and parallel rails 11 and 34 are laid at the same level on the upper surface of the turntable 33 and the upper surface of the support base 10, respectively, and the parallel rails 11 on the support base 10 are connected to the transport vehicle. The direction of movement of 31 is crossed. Further, two sets of parallel rails 34 on the turntable 33 are provided in the diametrical direction, and the winding machine 20 can be stopped on each set of parallel rails 34.

Note that 40 is the parallel rail 1 of the support base 10.
This is a transfer rail attached to the upper surface of the conveyance carriage 31 so that the winding machine 20 can be smoothly transferred from the winding machine 1 to the parallel rail 34 on the turntable 33.

The winding machine 20 includes a reel truck 22, and wheels 23 provided on the lower surface of the reel truck 22 are supported by parallel rails 11 and 34. This reel cart 22
A reel shaft 24 is rotatably supported at the center of the reel carriage 22, and the reel 21 is removably attached to the upper end of the reel shaft 24, which stands up from the upper surface of the reel truck 22. Further, a disc-shaped rotor 25 is attached to the lower end of the reel shaft 24 that protrudes downward from the lower surface of the reel truck 22, and a pair of columnar stators 26 that together with this rotor 25 constitute a linear motor. Three sets are provided, and one set of columnar stators 26 is laid on the upper surface of the support base 10. The remaining two sets of first and second columnar stators 26' and 26'' are provided on the turntable 33 parallel to the parallel rail 34.

The stator 26 includes stator windings, and when power is supplied to each of the stator windings, magnetic fields in opposite directions (indicated by arrows in FIG. 5) are formed in the pair of stators 26. Therefore, when a magnetic field of the same magnitude is formed in each stator 26, the rotor 25 rotates, and the reel shaft 24 can be rotated. In addition, by varying the magnitude of the magnetic field, the winding machine 20 can be moved between the parallel rails 11 and 3 with rotational force applied to the reel shaft 24.

Now, power is supplied to the pair of stators 26 on the support base 10 to rotate the reel shaft 24, and by winding the wire W guided by the traverser 2 around the outside of the reel 21, the wire W is can be wound up.

In addition, in the winding operation of the wire rod W, if the linear speed of the wire rod W and the circumferential speed of the wire rod winding portion of the reel 21 are different, the winding thickens, which needs to be corrected.

To correct winding thickening, either give the motor characteristics of a torque motor and control the primary voltage, or give it characteristics of a torque motor and control the rotation speed through feedback control using a combination of a rotary generator. There are ways to do it.

FIG. 12 shows an embodiment of the correction device.
This correction device functions as a torque motor,
A function for keeping the rotational speed constant can be switched by a changeover switch 50. When rotational speed control is selected with the switch 50, feedback control is performed so that the voltage proportional to the rotational speed from the rotational speed detector 51 provided on the outer periphery of the rotor 25 matches the set voltage of the speed setting device 52, Keep the rotation speed constant. Furthermore, when the changeover switch 50 is switched to the torque motor function, the set torque of the torque setting device 53 is output.

Next, when the wire rod W wound on the reel 21 reaches a predetermined winding diameter (hereinafter referred to as a full reel), the full reel A is replaced with an empty reel B. Before replacing the reel, perform the following preparations.

First, the winding machine 20 is placed on one parallel rail 34 on the turntable 33, and the winding machine 20

After changing the full reel A, turntable 3
3 is rotated 360 degrees, a part of the wire W from the traverser 2 to the full reel A comes to be wound around the outer periphery of the empty reel B (see FIG. 7). At this time,
The empty reel B is rotated in advance by supplying power to the second stator 26'', and the circumferential speed of the outer circumference of the empty reel B is made to match the moving speed of the wire rod W, in preparation for rewinding the wire rod. put.

After the turntable 33 stops rotating, the wire cutter device 60 provided on the table 33 is operated to cut a part of the wire from the full reel A that contacts a part of the outer periphery of the empty reel B. By placing the tip along the outer periphery of the empty reel B, the winding operation of the wire W can be continued with this empty reel B (see FIG. 8).
