本発明は圧延材の蛇行を制御する装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for controlling meandering of a rolled material.
［従来の技術］
圧延作業においては、圧延の条件によつて圧延
材がロールの中央に留まることができずに第４図
に示す如く圧延の進行とともにロール端部の方へ
移動してしまう現象がよく知られており、蛇行と
呼ばれている。[Prior Art] In rolling operations, there is a phenomenon in which the rolled material cannot stay in the center of the rolls depending on the rolling conditions, but moves toward the ends of the rolls as the rolling progresses, as shown in Figure 4. is well known and is called a meander.
ここで、圧延材の蛇行について簡単に説明する

し、近年圧延材の品質向上、歩留り向上の要求が
厳しくなると共に凸クラウンをできるだけ減らし
長手方向、幅方向共に均一な厚さ分布をもつよう
に圧延することが要求されている。このような条
件では圧延材の蛇行を発生させやすく、安定した
操業は難しい。 Here, to briefly explain the meandering of the rolled material, Fig. 3 shows a state in which the rolled material a has shifted to the right side from the center of the work roll b for some reason, and as shown in Fig. 3. As a result, the roll gap becomes uneven between the left and right sides, and the gap on the right side becomes wider than the left side. Incidentally, although the circumferential speed of work roll b is uniform on the left and right sides, the gap on the right side is wider, so the volumetric flow rate of the rolled material per unit time is larger on the right side. Also, if the thickness of the rolled material on the entry side is symmetrical, the material will be drawn in faster on the side with a larger volumetric flow rate. As a result, as shown in FIG. 4, the rolled material a moves to the right on the entry side (Δx), and a camber (Δy) occurs on the exit side. Therefore, the difference between the left and right roll gaps becomes even larger, and the rolled material a approaches the right end even more rapidly, causing a meandering phenomenon. At the same time, the camber also increases. As can be seen from this, meandering can be prevented by tightening the roll gap on the side where the rolled material approaches. Similarly, in order to prevent such meandering and the camber that accompanies it, it is effective to roll the material under conditions such that a convex crown is formed on the rolled material. However, in recent years, demands for improving the quality and yield of rolled materials have become stricter, and it has become necessary to reduce convex crowns as much as possible and to roll the materials so that they have a uniform thickness distribution in both the longitudinal and width directions. Under such conditions, the rolled material tends to meander, making stable operation difficult.
近年、上記蛇行を防止する手段の１つとして、
圧延材が蛇行すると、左右のロードセルｃ，ｄ
（第３図参照）にかかる力が変化するので、これ
を検出して蛇行を知り、荷重の増えた側のロール
ギヤツプを狭くするように圧下装置を動かして防
止しようとする手段が提案されている。 In recent years, as one of the means to prevent the above-mentioned meandering,
When the rolled material snakes, the left and right load cells c and d
(See Figure 3) Changes in the force applied to the roll gap (see Figure 3), so a method has been proposed in which this is detected, the meandering is known, and the roll-down device is moved to narrow the roll gap on the side where the load is increased to prevent it. .
しかし、上述の手段では、蛇行による荷重出力
変化と圧下装置を操作したための荷重出力変化が
重なつてしまう等の不具合があり、制御系が不安
定で発散振動を起し易く、又精度も不充分で全く
実用に耐えないという欠点がある。 However, with the above-mentioned means, there are problems such as the change in load output due to meandering and the change in load output due to operating the lowering device overlap, and the control system is unstable and tends to cause divergent vibration, and accuracy is also poor. The disadvantage is that it is insufficient and is not practical at all.
そこで、本件発明者等は上記問題点を解消する

を変更させるようにしている。 Therefore, in order to solve the above-mentioned problems, the inventors of the present invention proposed a meandering control means as shown in, for example, Japanese Patent Application No. 58-65109. The meandering control means is provided with an end position detector for detecting the width end position of the rolled material on the working side and the driving side on the entry side of the rolling machine,
A computing unit that calculates the meandering amount by computing the difference between the output signals of each end position detector and a setting device that gives the target position of the rolled material are provided, and the output signal of the computing unit and the target signal of the setting device are compared. It is equipped with a calculation device and a device that processes the signal obtained by the device and outputs it as a rolling reduction correction signal for the working side and the driving side, and changes the roll gap on the working side and the driving side based on the rolling reduction correction signal. I try to let them do it.

In this case, after the leveling adjustment, it is necessary for the worker to operate the setting device and reset the target value for the meandering control of the rolled material, resulting in a problem that the operation is complicated.

ンプ１５，１６に加えられるようになつている。 Figures 1 and 2 show an embodiment of the present invention, in which upper and lower work rolls 1 and 2, upper and lower back-up rolls 3 and 4, and both shaft ends of the upper and lower back-up rolls 3 and 4 are supported. Hydraulic cylinders 7, 8 which act on the lower back up roll jocks 5, 6 and the lower back up roll jocks 5, 6, respectively.
In a hydraulic reduction rolling mill 10 equipped with
The amount of pressure oil flowing into and out of the servo valves 11 and 12
At the same time, displacement detectors 13 and 14 for detecting the movement of the pistons of the hydraulic cylinders 7 and 8 are attached to the hydraulic cylinders 7 and 8, and signals from the displacement detectors 13 and 14 and meandering control are provided. Summing amplifiers 15 and 16 are provided to compare the signal from the regulator 21 or the manual leveling regulator 25.
The left and right roll gaps are set by controlling the amount of pressure oil flowing into and out of the hydraulic cylinders 7 and 8 using servo valves 11 and 12, and fluctuations in the roll gap are controlled by the pistons of the hydraulic cylinders 7 and 8. It is indirectly measured by displacement detectors 13 and 14 that detect movement, and compared with the set signal by adding amplifiers 15 and 16. If there is a difference, it is corrected by controlling servo valves 11 and 12 using the difference. Do it like this. Further, end position detectors 17a and 17b are installed on the left and right sides of the entrance side of the rolling mill 10 to detect the width end position of the rolled material 9 based on the light emitted,
The difference between the signals from the end position detectors 17a and 17b, that is, the meandering amount of the rolled material 9, is determined by the calculator 18, and the meandering amount is added to the storage circuit 19. A comparator 20 compares and calculates the obtained meandering amount deviation signal 22 with a target signal of
5, 16. The output of the regulator 21 is, for example, in the direction of tightening the roll gap on the working side and opening the roll gap on the driving side when the rolled material 9 moves toward the working side, and in the direction of opening the roll gap on the driving side when the rolled material 9 moves toward the driving side. In contrast to the above, the direction is determined and applied to the summing amplifiers 15 and 16 so that roll gap control is performed.

結果ロールの手動レベリング調整が行われる。 If it is necessary to adjust the leveling of the rolls during rolling, a worker operates the manual leveling adjuster 25. As a result, the changeover switch 26 is turned on, and the output of the meander control regulator 21 is held in a hold circuit (not shown). Therefore, an output signal proportional to the amount of lever operation of the manual leveling regulator 25 is given to the servo valves 11 and 12 via the addition amplifiers 15 and 16, and the servo valves 11 and 12 control the hydraulic cylinders 7 and 8. The amount of pressure oil flowing into and out of the roller is controlled, resulting in manual leveling adjustment of the rolls.

で戻される。 On the other hand, even during manual leveling adjustment, the width end position of the rolled material 9 is determined by the left and right end position detectors 17a, 17.
b, the signal is sent to the calculator 18, the meandering amount of the rolled material 9 is calculated, the result is sent to the memory circuit 19 via the changeover switch 26, and the manual leveling adjustment is completed and the manual leveling adjustment is completed. When the operation of the leveling regulator 25 is completed and a lock-on pulse at the start of meandering control is given to the switch 26, the meandering amount of the rolled material 9 at that time is stored in the memory circuit 19.
Thereafter, the meandering amount stored in this storage circuit 19 becomes the target value for meandering control. Further, when the operation of the manual leveling regulator 25 is completed and a lock-on pulse is issued, the changeover switch 26 is turned off, the hold state of the output of the meandering control regulator 21 is released, and the aforementioned meandering control is thereafter performed. . That is, the meandering amount calculated by the calculation unit 18 based on the signals detected by the end position detectors 17a and 17b is sent to the comparison calculation unit 20.
0, the meandering amount from the computing unit 18 and the target value from the storage circuit 19 are compared and calculated to produce the meandering amount deviation signal 2.
2 is output, and the meandering amount deviation signal 22 is processed by the meandering control regulator 21 and added to addition amplifiers 15 and 16 as left and right reduction correction signals. A comparison is made between the piston displacement signal and the reduction correction signal, and the difference signal is given to the servo valves 11 and 12, which control the amount of pressure oil flowing into and out of the hydraulic cylinders 7 and 8. As a result, the left and right roll gaps are changed, the meandering is prevented from further progressing by the mechanism described above, and the rolled material 9 is returned to the target value given by the memory circuit 19.
