Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a continuous winding control method for a single spooler that stores wire in an accumulator and continuously winds the wire by replacing the winding bobbin.

In this type of continuous winding method, the winding machine is generally driven at a speed controlled based on the take-up speed of the capstan, the amount of wire stored in the accumulator, and the winding amount of the winding machine. However, when replacing the winding bobbin of the winding machine and restarting winding on the new winding bobbin, the winding machine starts up by feeding out the wire stored in the accumulator. If this is done too quickly, the accumulator will not be able to follow suit and a shock will be applied to the wire, which may cause the wire to elongate, thin, or break. Also, when the winding bobbin is fully wound, the winder is lowered to stop it, but if this fall occurs suddenly,
The accumulator could not follow this, causing the wire to become loose, causing the wire to come off, and sometimes causing the line to stop.

SUMMARY OF THE INVENTION An object of the present invention is to provide a continuous winding method using a single spooler in which no impact is applied to the wire or the wire is loosened when the winding machine starts and falls.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 systematically shows an apparatus for carrying out a single spooler continuous winding method according to the present invention, in which a single spooler 10 is connected to a wire rod 12 to be wound. It consists of a capstan 14 that takes over wire rods 12 at a predetermined take-up speed, an accumulator 16 that stores the wire rods 12 fed from the capstan 14, and a winder 18 that winds up the wire rods 12 fed from the accumulator 16.

The capstan 14 is driven by a DC motor 22 whose drive is controlled by a drive unit 20.
The drive unit 20 is controlled by a take-up speed signal S1 set by a potentiometer VR1 and supplied via a switch SW1 and an integrator IG1. This drive unit 20 has an inclination a of FIG.
The capstan 14 is driven and controlled as indicated by a'. Note that this capstan 14 is normally driven at a predetermined take-up speed V1 at all times, except when the entire line of the apparatus is stopped.

The winder 18 is driven by a DC motor 26 whose drive is controlled by a drive unit 24. The drive unit 24 is controlled by a control signal S2 from the operational amplifier AMP1. In addition, DC motor 2
The rotational speed signal from the rotational speed detector 28 which detects the rotational speed of the DC motor 26 is fed back to the drive unit 24, is compared with the control signal S2, and is corrected so as to rotate the DC motor 26 at a predetermined rotational speed.

The take-up speed of the capstan 14 is controlled by the DC motor 22.
The take-up speed signal (master signal) S3 detected by the rotation speed detector 30 is supplied to the drive unit 20 for the purpose of correction, and is also sent to the operational amplifier.
Also supplied to AMP2. The amount of accumulated radiation in the accumulator 16 is detected by the accumulator position detector SC, and the accumulated line signal S4 detected by the accumulator position detector SC is supplied to the operational amplifier AMP2 via the rectifier RC. In addition, the operational amplifier AMP2 includes a comparator along with the storage line signal S4.
A winding thickening signal S5 corresponding to the winding amount of the winding drum is supplied from COMP. The operational amplifier AMP2 receives these signals S3, S4, and S5 and supplies a winding control signal S6 to the operational amplifier AMP1 via a switch R1 that is closed during normal winding operation. Further, the winding control signal S6 from the operational amplifier AMP2 is supplied to the integrator IG2 via a switch R2 which is closed when the winding drum 26 is started, and the output of this integrator IG2 is supplied to the operational amplifier AMP1. On the other hand, the detection signal of the rotation speed detector 28 that detects the rotation speed of the DC motor 26 is supplied to the integrator IG3 via the normally closed switch R3, and the winding speed of the winding machine 18 at that time is stored. , this integrator
The output of IG3 is a normally open switch R3' that is closed by a measuring signal from the measuring device 32 of the winding device 10.
The signal is then supplied to the operational amplifier AMP1. integrator
IG2 generates a signal with a slope such that the winding speed of the winding drum gradually rises, and also an integrator
IG3 generates a signal having a slope that gradually falls from the final winding speed of the winding drum.

Therefore, when the wire 12 is being normally wound on the winder 18, the DC motor 26 that rotationally drives the winder 18 with only switches R1 and R3 closed receives the take-up speed signal S3 and the storage. A winding control signal S6 is generated by calculation using the line signal S4 and the winding thickening signal S5, and this control signal S6 is supplied to the operational amplifier AMP1 and then supplied to the drive unit 24 as a final control signal S2. Drive the DC motor 26. As shown in FIG. 1, the upper part of the accumulator 16 with respect to the broken line position of the movable roll is a winding control range, and the lower part is a storage line range. During this normal winding, the DC motor 26 is controlled and driven so that the accumulator 16 is within the winding control range. For this reason, the operational amplifier
AMP2 sets the take-up speed signal S3 to 50%, and the storage line signal S
4 is calculated as ±60%, and a winding control signal S6 of 100% to 40% is supplied to the operational amplifier AMP1. still,
As shown by C in FIG. 2, the number of rotations of the drum decreases according to the thickness of the roll, so that the winding speed is always constant.

After the winding of the winding machine 18 is wound up by a predetermined amount, the measuring device 3
When a metering signal is generated from 2, the control unit 34
(See FIG. 1, bottom) opens switches R1 and R3 and closes switch R3'. As already mentioned,
The integrator IG3 receives and stores the current take-up speed signal from the rotation speed detector 28 before the meter signal is input, so when the meter signal is input, the output of the integrator IG3 is supplied to the operational amplifier AMP1. , the output of which controls the drive unit 24 based on the control signal from the integrator IG3. As already mentioned, the control signal from the integrator IG3 decelerates and stops at a winding speed that attenuates with a gentle slope from the winding speed immediately before the meter signal is input (see FIG. 2e). It is preferable that this attenuation characteristic is normally about 10 seconds.

In this way, when the winding machine 18 stops, the capstan 14 is continuously driven during this period, and the wire rod 12 is stored in the accumulator 16, so that the wire rod 12 is stored in the accumulator 16, so that the wire rod 12 is stored in the accumulator 16. Remove the chuck 36 from the drum 19A, move it to the right in the figure by the conveyor 38, and remove the chuck 36 from the new empty drum 19A.
Bring B to the winding position and close the chuck 36,
The wire rod 12 portion is cut by the cutter 40 to separate the winding drum 19A, and the end of the supplied wire rod is fixed to the empty drum 19B.
Start winding the wire around 9B. At the beginning of winding on the drum 19B, the control unit 34 closes switches R2 and R3 and opens R3', so the output of the integrator IG2 is supplied to the operational amplifier AMP1 and the winding machine 1
8 is performed while slowly rising.

According to the present invention, as mentioned above, since the winding machine rises and falls slowly, no shock is applied to the wire between it and the accumulator, and wire elongation, wire thinning, wire breakage, and loosening occur. There is a practical benefit in that the wire rod can be continuously wound without any problems.
