The driving unit 20 is adapted to control the drive of the capstan 14.

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 seven cumulators 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 hobbin of the first winding machine and restarting winding on a new winding bobbin, the winding machine starts up by feeding out the wire stored in the accumulator, but this start-up is 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 take-up bobbin is fully wound, it is lowered to stop the winder, but this fZ
If the downward movement occurs rapidly, the accumulator cannot follow this and the wire loosens, causing the line to come off.
Sometimes there were prisoners that caused the line to stop.

SUMMARY OF THE INVENTION An object of the present invention is to provide a continuous winding force increasing method for a single spooler in which no impact is applied to the wire rod or the wire rod is loosened when the winder 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 the wire at a predetermined take-up speed, an accumulator 16 that stores the wire 12 fed from the capstan 14, and a winder 18 that winds the wire 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, which is controlled by a take-up speed signal S1 set by a potentiometer R1 and supplied via a switch SWI and an integrator IGl. This drive unit 20 drives and controls the capstan 14 as shown by M diagonals a and a' in FIG. 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 . Drive unit 24
is controlled by a control signal S2 from operational amplifier AMP1. Note that the rotation speed signal from the rotation speed detector 28 that detects the rotation speed of the DC motor 26 is fed back to the drive unit 24 and compared with the control signal S2, and corrected so that the DC motor 26 rotates at a predetermined rotation speed. capstan 14
The take-up speed is detected by a rotation speed detector 30 that detects the rotation speed of the DC motor 22, and the take-up speed signal (master signal) 33 detected by this rotation speed detector 30 is supplied to the drive unit 20 for the purpose of correction. It is also supplied to the operational amplifier AMP2. The amount of radiation stored in the accumulator 16 is detected by the accumulator position detector SC, and the storage signal S4 detected by the accumulator position detector SC is supplied to the operational amplifier AMP2 via the rectifier RC. In addition, along with the storage line signal S4, the operational amplifier AMP2
A winding thickening signal S5 corresponding to the winding amount of the winding drum is supplied from the comparator COMF. Operational amplifier AMP2 manually inputs these signals S3 and 34°S5 and sends them to operational amplifier AMPI via switch R1, which is closed during normal winding operation.
A winding control signal S6 is supplied to the winding control signal S6. Further, the winding control signal S6 from the operational amplifier AMP2 is supplied to the integrator IG2 via a switch R2 that is closed when the winding drum 26 is started, and the output of this integrator IG2 is fed to the operational amplifier AMP1.
supplied to 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 machine 18
The output of the integrator IG3 is supplied to the operational amplifier AMPI via a normally open switch R3' which is closed by a measuring signal from the measuring device 32 of the winding device 10. The integrator IG2 generates a signal having a slope such that the winding speed of the winding drum gradually rises, and the integrator IG3 generates a signal having a slope such that the winding speed of the winding drum gradually falls from the final winding speed. occurs.

Therefore, when the wire 12 is being normally wound on the winder 18, only the switches R1 and R3 are closed, and the DC motor 26 that rotationally drives the winder 18 receives the take-up speed signal S3 and the wire storage. A winding control signal S6 is generated by calculating the signal S4 and the winding thickening signal S5, and this control signal S6 is supplied to the operational amplifier AMPI to generate the final control signal S2.
The signal is supplied to the drive unit 24 as a signal.

The DC motor 26 is driven. Furthermore, as shown in Figure 1,
The upper part of the accumulator 16 is the winding control range, and the lower part is the storage! ! range. During this normal winding, the DC motor 26 is controlled and driven so that the accumulator 16 is within the winding control range. Therefore, the operational amplifier AMP2 calculates the take-up speed signal S3 as 50% and the wire storage signal S4 as ±60%, and supplies the signal S6 to the operational amplifier AMP1 for winding control from 110% to 40%. 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 remains constant.

When a predetermined amount of the winding machine 18 is wound up and a measuring signal is generated from the measuring device 32, the control unit 34 (see the lower part of FIG. 1) opens the switches R1 and R3 and closes the switch R3'. As already mentioned, the integrator IG3 receives and stores the current winding speed signal from the rotational 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,
Its output 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 is attenuated with a gentle slope from the winding speed immediately before the meter signal is input (see FIG. 2e). This damping characteristic is preferably about 10 seconds.

When the second winder 18 is stopped in this way.

Since the capstan 14 is being driven continuously during this period, the wire rod 12 is stored in the accumulator 16. During this period, as shown in Fig. 83, the chuck 36 is removed from the fi-winding drum 19A, and the conveyor 38 moves the wire rod 12 to the right side of the figure. 2, move the new empty drum 19B to the winding position, close the chuck 36, cut the wire 12 portion with the cutter 40 to separate the winding drum 19A, and remove the end of the supplied wire from the empty drum 19B. This drum 1
Start winding the wire around 9B.

The control unit 34 closes switches R2 and R3 and opens R3' to start winding on the drum 19B, so the output of the integrator IG2 is supplied to the operational amplifier AMP1 and the winding machine 18 is gradually started up. It will be done.

According to the present invention, as mentioned above, the rise and fall of the 9-winding machine are performed gently, so there is no impact on the wire between it and the accumulator, which prevents wire elongation, thinning, wire breakage, and loosening. There is a practical benefit in that the wire rod can be continuously wound without any problems.
