To be That is, as for the drive shaft 31, (a) the winding drum shaft 1 is clutched (Fig. 4) (b) the winding drum shaft 2 is clutched (Fig. 1) (c) Neutral (Fig. 5) As for the shaft 32, (a) the winding drum shaft 1 is clutched (Fig. 1) (b) The winding drum shaft 2 is clutched (Fig. 6) (c) Neutral (Fig. 7) , The pinion 13 and the clutch 17 are connected, and the pinion 13 is connected to the winding barrel shaft 2 by the gear 8, the intermediate shaft 10, the gear 6, and the pinion 4, so that the motor of large torque (first The motor) 20 rotates the winding cylinder II through the clutch inner cylinder 16 and the clutch 17. On the other hand, the winding drum shaft 1 also has a pinion 5, a gear 7, an intermediate shaft 11, and a gear.
Since the pinion 14, the clutch 18, and the clutch cylinder 19 are connected to each other, the pinion 14 is rotationally driven by a small torque motor (second motor) 21.

On the other hand, in FIG. 6, the housing 3 revolves from the state of FIG. 1, the clutch 17 separates from the pinion 13 and is connected to the pinion 12 on the opposite side, and the winding drum I is connected to the first motor 20. Further, the clutch 18 is also separated from the pinion 14 and connected to the pinion 15 on the opposite side, and the winding cylinder II is connected to the second motor 21.

As described above, the rotation drive of the winding drums I and II (hereinafter, referred to as rotation) is performed by the first switching operation of the gear clutches 17 and 18.
The motor 20 and the second motor 21 are alternately operated.

FIG. 8 is a block diagram showing the winding speed tuning control system. The rotation shafts of the first motor 20 and the second motor 21 are provided with pulse counters 27, 28 for detecting respective rotation speeds Ns, Nd. Installed and this pulse counter 27,28
The rotation speeds Ns and Nd detected in step S4 are input to the arithmetic unit 29. The arithmetic device 29 compares and collates the detected rotation speeds Ns and Nd and inputs a signal of the deviation to the control device 30, so that the rotation speed Ns of the first motor 20 matches the rotation speed Nd of the second motor 21. To control.

Although not shown, the second motor 21 is connected to a control device that controls winding weight and tension as in the conventional case. On the other hand, the control device 30 connected to the first motor 20 is provided with a function of performing winding weight control and tension control in addition to the rotation control function as described above.

Next, the state and operation of each part will be described along with the actual winding procedure.

FIG. 9 is a view showing a state in which the strip 22 is wound up by the winding drum II, and at this time, the belt wrapper 26 is wound around the winding drum I.
Is installed and is spinning in preparation for the next coil winding. The state of each part shown in FIG. 1 corresponds to the state shown in FIG. 9, and the winding drum I is moved by the gear clutch 18 to the second motor 21.
And is rotated at a low speed (for example, the passing speed of the next coil strip) in preparation for winding the next coil. on the other hand,
Since the winding drum II is connected to the first motor 20 by the gear clutch 17, the stop 22 is wound by the first motor 20.

FIG. 10 shows a state at the end of winding of the winding cylinder II, in which the strip 22 which is continuously rolled by the mill 23 is divided and cut by the shearing machine 24 to wind the preceding coil 41. After the above, the first motor 20 is stopped and the coil 41 is removed from the winding drum II in the normal operation. On the other hand, the cut subsequent strip 22 is sent to the winding drum I and wound around the winding drum I by the belt wrapper 26. Then, as the second motor 21 is driven to rotate, it is wound as a next coil. The connection state of the drive system at this time is the same as that in FIG.
The winding by 21 is performed at a low speed close to the strip passing speed.

On the other hand, at this time, for the winding cylinder II that has finished winding, a clutch switching command is input to the clutch operation control device 38, and the clutch 17 is switched to the neutral position, so that the clutch 17 is separated from the clutch 17, 1 motor 20 has drive shaft 31
It will be in the state of driving only. Then, after the first motor 20 is stopped, if the coil 41 is removed, the first motor 20 starts to rotate again, but the rotation speed Ns of the second motor 21 is set by the control system shown in FIG. The rotation speed is controlled so as to match the rotation speed Nd of and the same rotation direction.

As a result, when Ns = Nd, the clutch 17 and pinion
12 rotations have the same rotation speed in the same direction, and the pinion
The relative velocity between 12 and clutch 17 becomes zero. At this time,
As shown in FIG. 4, the clutch 17 is moved to connect with the pinion 12. After the connection is completed, the control by the control device 38 is switched from the speed tuning control to the winding control, and at the same time, the second motor is controlled.
Stop 21. Therefore, at this time, the winding drive source of the winding drum I is switched from the second motor 21 to the first motor 20. After this, until the winding by the winding drum I is completed, the second motor 21
Does not need to be rotated, a command is given to the controller 47 to disengage the clutch 18 as shown in FIG.
And the second motor 21 are separated from each other, and the second motor 21 is braked and stopped.

On the other hand, the winding drum I is accelerated by the first motor 20 and reaches a predetermined maximum winding speed. Up to this state, the housing 3 does not revolve after winding on the winding drum I, and the positional relationship between the winding drum I and the deflector roll 25 has not changed.

Next, as shown in FIG. 11, the housing 3 supported by the wheels 50 on the base 51 by an unillustrated revolution driving device is rotated 180 ° in the clockwise direction in FIG. Move the position. After that, continue winding in this state,
It will be in the same state as the figure. The drive system is in the state shown in FIG. 6 in the state shown in FIG. Further, when the winding drum I starts to wind (FIG. 12), the drive system is in the state shown in FIG.

By repeating the above operation, continuous winding can be performed without stopping the mill 23.

The housing 3 may be revolved after switching the drive of the winding drum I from the second motor 21 to the first motor 20.

In this way, by switching the drive source of the winding cylinder between the start of winding and the winding thereafter, a small torque motor can be used as the second motor 21. That is, at the beginning of winding, the winding diameter is small and the winding diameter is small, so that a motor with a small output and a small torque can be used.

By the way, tension 5000Kg, coil diameter 2500mm, maximum winding speed
2500m / min, the first motor output 2042kW, output torque 625
It is assumed that 0 kg / m is used, and the plate passing speed is 3
If the winding diameter of the second motor 21 is 1000 mm at 00 m / min, the second
As the motor 21, a small motor having an output of 245 kW and an output torque of 2500 Kg · m, which is about 1/8 of the first motor, can be used. As a result, the power supply for the second motor 21 can be small, and the control diameter can be small. Therefore, despite the addition of a drive switching mechanism such as a clutch, the overall scale becomes smaller,
It is space-saving and extremely economical.
