も行なう。 In such a conventional apparatus, at the start of overlapping rolling, first, only the upper material 1 and the lower material 2 are passed to the crimping stand 10 at a predetermined low speed. Next, the operator inserts the intermediate material 3 between the upper material 1 and the lower material 2, and starts overlapping rolling at a low speed. Then, while the slack in the intermediate material 3 provided on the input side of the intermediate material pinch roller 9 is being removed, the operator starts the intermediate material 3 and operates the target value setting device 20 to set the intermediate material 3. As the speed increases, the intermediate material 3 and the upper and lower materials 1 and 2 are adjusted to have the same speed when the slack is gone. After confirming that overlapping rolling is being performed reliably at low speed, the operator accelerates the entire line to a predetermined steady rolling speed and begins steady rolling. Further, in the above process, the operator finely adjusts the speed setting device 18 from beginning to end and performs tension control so that an appropriate tension is always applied to the intermediate material 3.

When a start command is received, the calculated low speed is output to the intermediate material speed control device 19 as the target speed during initial rolling, and when a re-acceleration command, which will be described later, is received, the target speed set by the operator is set as the target speed during steady rolling. It is output to the intermediate material speed control device 19. Here, the target speed during steady rolling is usually set to the same speed as the steady rolling speed in the crimping stand 10. Further, the speed difference is the intermediate material 3

That is, when the tension control device 25 detects that the tension detection value by the tension detector 24 has risen above a predetermined reference tension, it outputs a rise detection signal to the timing detection device 27, and the timing detection device 27 detects the rise. Immediately upon receiving the detection signal, a tension control start command is output to the tension control device 25. Tension control device 2

When the timing detection device 27 detects that the rolling speed detection value from the rolling speed detector 28 has reached the steady rolling speed, it sends the intermediate material start command to the target speed calculation circuit 22, and then, as described above, When the rising detection signal is input from the tension control device 25, the tension control start signal is sent back to the tension control device 25, and the target speed calculation circuit 22

通板時速度基準へ向けて加速して行く。 In FIGS. 1 and 2, at the start of rolling, only the upper material 1 and the lower material 2 are passed through the crimping stand 10, and rolling of only the upper material 1 and the lower material 2 is started (time t 1 ). When the rolling speed (FIG. 2a) increases and reaches the steady rolling speed, the intermediate material start command is output from the timing detection device 27 to the target speed calculation circuit 22, and the target speed calculation circuit 2
2, the speed reference at the time of initial sheet passing is outputted (time t 2 ). At this time, since the speed correction amount has not yet been output from the tension control device 25, the target speed at the time of initial sheet passing is inputted to the speed control device 19 as is. As a result, the speed control device 19 starts the roll groups 13 to 16 via the drive device 17 (time
t 3 ), the intermediate material 3 is accelerated toward the initial sheet passing speed reference as shown in graph b.

とになる。 In addition, the intermediate material pinch rolls 9 are also activated around the time when the intermediate material 3 starts to be conveyed, and when the tip of the intermediate material 3 is inserted between the upper and lower materials 1 and 2, the upper and lower materials 1 and 2
Pressing and rolling of the intermediate material 3 and the intermediate material 3 is started. Since this compression rolling is carried out at the steady rolling speed,
The slack in the intermediate material 3 provided on the entry side of the intermediate material pinch roll 9 disappears, and in the meantime, the intermediate material speed reaches the target speed at the initial threading (time
t4 ). Since this target speed at the time of initial sheet passing is lower than the rolling speed of the crimping stand 10 at this time, that is, the steady rolling speed by the speed difference α, the intermediate material 3 is is pulled from the crimping stand 10 and the tension suddenly rises. In other words, this rise in tension is caused by the intermediate material 3
is an index indicating that the sheet has been reliably passed through the crimp stand 10. When the tension control device 25 detects the rise based on whether the tension reaches a predetermined reference tension or more, it outputs the rise detection signal to the timing detection device 27. As a result, the intermediate material re-acceleration command is sent from the timing detection device 27 to the target speed calculation circuit 22, and the target speed during steady rolling is outputted from the target speed calculation circuit 22.
At the same time, the timing detection device 27 sends the tension control start command to the tension control device 25, and the tension control device 25 outputs a speed correction amount corresponding to the tension deviation. The steady rolling target speed and the speed correction amount are added by the adder 23 and input to the speed control device 19, and the speed control device 19 re-accelerates the intermediate material 3 according to the input target speed ( time t5 ). That is, the speed control device 19 accelerates the intermediate material 3 toward the steady rolling speed while performing tension control so that the tension of the intermediate material 3 approaches the target tension, and rolls the intermediate material 3 to almost the steady rolling speed. After accelerating to the same speed (time t 6 ), the speed control shifts to steady rolling. In this way, the initial threading of the intermediate material 3 is automatically and smoothly performed.
次に、定常圧延時の動作について説明する。 Next, the operation during steady rolling will be explained.

Figure A shows the relationship between the tension of the intermediate material 3 and the target tension, Figure B shows the holding operation of the speed correction amount performed inside the tension control device 25, and Figure C shows the state of the speed correction amount. Each is shown below.

前記張力が降下し前記張力制御範囲内に入ると
（時刻t7）、張力制御装置２６はその時の速度補正
量を保持する。 As shown in FIG. 3, the tension control device 2
5, when the target tension is given, sets a tension control range of a predetermined width centered on the target tension as shown by hatching, and sets its upper limit as the target tension upper limit,
The lower limit value is determined as the target tension lower limit value. When the tension of the intermediate material 3 is larger than the target tension upper limit value, the tension control device 25 calculates and outputs a speed correction amount corresponding to the tension deviation, whereby the intermediate material 3 is accelerated and its tension is lowered. controlled. As a result, when the tension decreases and enters the tension control range (time t7 ), the tension control device 26 maintains the speed correction amount at that time.
これにより前記速度補正量は前張力の変化とは
関係なく一定に保たれるため、前記張力はいつか
は前記張力基準上限値又は下限値のどちらかをは
ずれることになる。例えば、前記張力が前記目標

制御装置２５は前記速度補正量の保持を解除し再

する。その結果、中間材３は減速されその張力は
上げ方向へ制御される。 As a result, the speed correction amount is kept constant regardless of changes in the pre-tension, so the tension will eventually deviate from either the tension reference upper limit or lower limit. For example, if the tension becomes equal to or less than the target tension lower limit (time t 8 ), the tension control device 25 releases the holding of the speed correction amount and again calculates and outputs the speed correction amount corresponding to the tension deviation. . As a result, the intermediate material 3 is decelerated and its tension is controlled in the upward direction.
このようにして、張力制御装置２５は、前記張

たれ製品の歩留りが向上する。 In this way, the tension control device 25 maintains the speed correction amount when the tension is within the tension control range, and when the tension falls outside the tension control range, the tension control device 25 corrects the speed according to the tension deviation. Control is executed to output the amount and accelerate/decelerate the intermediate material 3 to return the tension to the tension control range. As a result, the intermediate material 3 is threaded while its tension is almost always kept within the tension control range, and as a result, the thickness of the intermediate material 3 is kept almost uniform, improving the product yield. .

になされるならば問題はなく、このようにしても
円滑に中間材３の初期通板を行うことができる。 In this modification, the timing detection device 2
7 outputs only the intermediate material re-acceleration command when receiving the rising detection signal from the tension control device 25;
As a result, the intermediate material is accelerated again, and the tension control start command is output when the speed reaches a predetermined ratio to the steady rolling speed, for example, when the speed becomes equal to the steady rolling speed. Therefore, tension control is not performed while the intermediate material 3 is being re-accelerated, but there is no problem as long as the re-acceleration is done quickly, and even if this is done, the initial threading of the intermediate material 3 can be carried out smoothly. It can be carried out.

As explained above, according to the first and second inventions, the intermediate material is threaded between the plates at a speed lower than the rolling speed, and the threading of the intermediate material is ensured from the rise of tension in the intermediate material. Since this is detected and the intermediate material is accelerated to the rolling speed, the initial threading of the intermediate material can be performed automatically without relying on manual operations by an operator.

Yield is also improved.
