Abstract

PURPOSE:To obviate any secondary receiving device otherwise required to be provided between an accumulator and a takeup machine in an arrangement, where a film is stagnated in the accumulator at the time of web replacement, by operating the accumulator in compliance with the speed of a receiving device, and specifying the takeup reference speed in linkage therewith. CONSTITUTION:Normally a receiving device I is operated being tuned with the line speed LV by the speed control system due to feedback correction of the first dancer correction device d1, while a takeup machine III operates with its takeup shaft A driven while the speed is corrected by the second dancer correction device d2, wherein the receiving speed HV sensed by a receiving speed sensor TG-1 is used as the takeup speed. When therein a replace signal is given from the takeup machine 3, a drive motor M2 for an accumulator II is started operating upon calculating necessary operating speed for absorbing surplus or shortage of web in compliance with stop of the takeup machine III or its pursuit operation, which is conducted based upon the receiving speed HV. The reference speed of the takeup machine III is computed from this operating speed, and type takeup speed is controlled with this reference speed.

Next, the operation of the take-up / winding control circuit having the above structure will be described with reference to FIGS. 1 and 2. The take-up device (I) uses the preceding process speed (LV) as a speed signal,
It is corrected by the first dancer correction device (d 1 ), and the motor (M 1 ) is always operated in synchronization with the previous process. In the winding machine (III), during normal operation, the take-up speed (HV) detected by the take-up speed detector (TG-1) is used as a take-up speed signal, and the speed is corrected by the dancer (d 2 ) to make the take-up shaft. Although (A) is driven, when the rewinding signal is transmitted from the winder (III), the following control is performed. First,
The switching contact (a) is closed (time t 1 shown in FIG. 2), and the accumulator drive motor (M 2 ) has the speed gradient set by the acceleration / deceleration adjuster (LT-1) and the proportional controller (P 1 ), It is started toward the speed (HV / 2n) set and the accumulator (II) starts to rise. The speed of the accumulator drive motor (M 2 ) is
It reaches HV / 2n at time t 2 , and thereafter, the accumulator (II) continues to rise at this speed (HV / 2n) until time t 3 . At the same time, after the time point t 1 , the contact (d) is also closed, and the accumulator rising speed (AV) detected by the ascending / descending speed detector (TG-2) is the polarity reversing device (3) and the proportional controller ( P 3) becomes -2nAV by being output to the abutting point (4), the point butt (4), WV = HV- 2nAV as winding speed signal
Is output.

[0013] Thus increasing the rate of 2n times the speed signal in the accumulator acceleration period (t 1 ~t 2) is constantly accumulator (II) becomes a be subtracted from the take-up speed (HV), the winding speed Decelerate while taking the speed of the subtraction result. As a result, when the accumulator rising speed (AV) reaches (HV / 2n) at time t 2 , WV = HV-2n.AV = HV-2n.HV /
2n = 0, the winder (III) is stopped, and thereafter the winder (III) is stopped while the accumulator is rising at a constant speed (AV = HV / 2n) (t 2 to t 3 ). Keep the state. During this period, the positions of the winding shafts (A) and (B) of the twin-screw turret in the winding machine (III) are exchanged, and various operations required for the rewinding (separation of the web, winding on a new winding shaft, etc.) ) Is carried out. Further, since the changeover switch (c) is switched during the period, the speed correction of the second dancer correction device (d 2 ) is transferred to the rising speed correction of the accumulator (III), and the winder (I)
In II), the stall tension setting device (ST) is attached to the A-axis that has been repositioned by the 2-axis turret rotation.
The stall tension set by is applied.

Next, at time t 3 , the contact of the changeover switch (a) is opened and the contact (b) is closed, so that the take-up speed (HV) is changed to-by the polarity reversing device (2), and the acceleration / deceleration is performed. -Α ・ by the gradient set by the speed governor (LT 2 ) and the constant (α / 2n) set by the proportional controller (P 2 ).
HV / 2n is output as the speed signal of the accumulator (II). Therefore, the accumulator drive motor (M 2 ) decelerates, the rotation direction reverses at time t 4 , and is driven at a speed of −α · HV / 2n at time t 5 .
As a result, the accumulator (II) gradually decreases the rising speed from time t 3 to time t 4 ,
It reverses to the descending direction at the 4th time point, and at a constant time point at the 5th time point -α ・
It becomes HV / 2n and continues to fall. In the meantime, in the winding machine (III), the position is changed during the stop and the winding is performed on the B-axis side, and thereafter, the B-axis becomes a control target. In that case, since 2n times of the deceleration speed is subtracted from the take-up speed (HV) with respect to the ascending speed deceleration of the accumulator (II) during the period of t 3 to t 4 , the turret is moved to the winding position. When the speed of the changed B-axis rises and it coincides with the take-up speed (HV) at time t 4 , 2n times the descending speed of the accumulator (II) is accompanied by the reversal of the accumulator (II). The speed is added to the take-up speed (HV), and at time t 5 , the winder (III) moves to HV + 2n · αHV / 2n =
It is driven at a chasing speed of (1 + α) HV. Since the contact of the changeover switch (c) is switched at time t 3 , the correction signal of the second dancer correction device (d 2 ) is switched to the speed correction of the winder (III). Accumulator (II) continues to descend and return to the old position, the changeover switch (b) is caused to open (t 6 time), the accumulator drive motor (M2) stops deceleration (between t 6 ~t 7), The accumulator (II) stops descending. Accumulator (I
The decelerating speed of (I) is also the same as that of the winder (II).
I) Since it acts on the speed signal matching point (4), t 7
At this time, the B-axis is driven at a speed that is synchronized with the take-up speed (HV), and at this time, the changeover switch (d) is opened.

The control method may be changed to that shown in FIG. The difference between the control methods shown in FIG. 3 is that the changeover switch (a) is set at the operation start time t 1
From the point where the accumulator (II) returns to the previous position t 6 and the ratio of the ratio controller (P 2 ) in the second circuit (12) for raising and lowering the accumulator (II) is (1 + α) / 2n.

As described above, according to the method of the present invention, in the take-up / take-up device including the take-up device, the accumulator and the take-up machine, the accumulator is first operated at a predetermined speed based on the take-up speed signal of the take-up device. This is a method of controlling the winding speed of the winding machine by the operation of the accumulator. Since the winding reference speed of the winding machine is not obtained by a device such as the second take-up device as in the conventional case, the process device is shortened. Is effective in Further, since the control flow is along the flow of the web, extremely accurate control can be easily realized without the double error from the preceding and following steps intervening particularly in the control of the accumulator. Further, the apparatus according to claim 2 operates the accumulator through the first speed command control system and the second speed command control system at a speed based on the take-up device of the take-up device, and changes the operating speed of the accumulator. Since the winding reference speed is transmitted to the winding machine via the detection circuit and the adding / subtracting means to enable the winding control, a remarkable effect is obtained in shortening the process equipment and reducing the equipment cost.
