た形状検出器に関するものでおる。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a shape detector capable of detecting the tension distribution of a plate such as a rolled material.
［従来の技術１
圧延板幅方向の張力分布を調整することにより圧延はで
圧延された板の平面形状が良好になるよう制御すること
は従来から行われている。[Prior Art 1] It has been conventionally practiced to control the planar shape of a rolled plate by adjusting the tension distribution in the width direction of the rolled plate.
而して、この制御を行う際には圧延材の幅方向張力分布
を測定するために形状検出器が使用されでいる。When performing this control, a shape detector is used to measure the tension distribution in the width direction of the rolled material.
従、来の形状検出器の一例は第５図及び第６図に示され

例えば磁歪式ゲージｆをセットした片状体ｇか嵌入され
ている。An example of a conventional shape detector is shown in FIGS. 5 and 6, where a is a rolling machine and b is a shape detector for detecting the tension distribution of a rolled material S rolled by a rolling la. . The shaft C of the shape detector is rotatably supported by a bearing (not shown), and on the outer periphery of the shaft C are divided into a small number of parts at required intervals in the axial direction, which rotate integrally with the shaft C. The annular body d thus obtained is fitted. Further, on the outer periphery of the shaft body C, a plurality of recesses e are provided in the circumferential direction corresponding to each annular body d, and a piece-like body g in which, for example, a magnetostrictive gauge f is set is fitted into the recess e. .
斯かる形状検出器すては、圧延機ａて圧延された圧延材
Ｓは環状体ｄと所定の巻付は角度で巻付けられ、軸体Ｃ
及び環状体ｄは圧延材Ｓの送り速度に同期した回転速度
で回転させられ、磁歪式ゲージｆの磁力密度の変化から
圧延材Ｓの張力が検出される。In all such shape detectors, a rolled material S rolled by a rolling mill a is wound around an annular body d at a predetermined angle, and a shaft body C
The annular body d is rotated at a rotational speed synchronized with the feed rate of the rolled material S, and the tension of the rolled material S is detected from a change in the magnetic density of the magnetostrictive gauge f.
従来の形状検出器の他の例としては第７図及び第８図に
示ずものが必り、形状検出器りの固定軸体１の外周には
、軸方向へ所要の間隔て復故に分割され夫々か単独で回
転し得るようにした回転子ｊ′ｈ′Ｎ嵌合されている。Other examples of conventional shape detectors include those not shown in FIGS. 7 and 8, in which the outer periphery of the fixed shaft body 1 of the shape detector is divided at required intervals in the axial direction. A rotor j'h'N is fitted so that each rotor can rotate independently.
又固定軸体ｉには、各回転子Ｊに対応して放射状に空気
噴射口ｋが設けられ、回転子Ｊと固定軸体ｉとの間に空
気軸受が形成されるようになっている。Further, the fixed shaft body i is provided with air injection ports k radially corresponding to each rotor J, so that an air bearing is formed between the rotor J and the fixed shaft body i.
Ｂ、ｒかる形状検出器りでは、圧延機ａで圧延された圧
延材Ｓは回転子ｊに接触して送られ、回転子ｊは圧延材
Ｓにより回転させられる。又圧延材Ｓの張力変動により
空気噴射口ｋから噴射される空気圧は変動するため、こ
の空気圧の変動から圧延材Ｓの張力が検出される。In the shape detectors B and r, the rolled material S rolled by the rolling mill a is sent in contact with the rotor j, and the rotor j is rotated by the rolled material S. Further, since the air pressure injected from the air injection port k changes due to the fluctuation of the tension of the rolled material S, the tension of the rolled material S is detected from the fluctuation of this air pressure.

A roll mark is attached to the rolled material S depending on the part, and an annular body d,
There is a risk that rolling oil, etc. that has entered the gap between d may seep out when the tension of the rolled material S is detected and mark the rolled material S. Roll marks may be formed on the rolled material S, air and bearings cannot increase the air pressure, so there is a limit to their load capacity, and if the tension in the rolled material S is high, it will be impossible to detect it, etc. There was a problem.
本発明は上述の実情に鑑み、圧延材にロールマークや圧
延油等によるマークが付かず且つ圧延材張力が大きい場

も十分使用できる。When detecting the tension distribution of the rolled material S, the hollow cylindrical body 1 is driven by the frictional force with the rolled material S, and the widthwise tension of the rolled vJS is detected by the deformation of the thin wall portion of each load detector 80 and the cylindrical case 9. Since the hollow cylindrical body 1 is not divided in the axial direction and is integral, the rolled material S
Since the rolling oil and the like do not penetrate into the hollow cylindrical body 1, the rolled material S will not be marked by rolling oil. Furthermore, since the tension in the rolled material S is detected by the strain gauge 20 through the thin wall portion of the cylindrical case 9, the load capacity limit is not as low as in the case of air bearings, and therefore the tension in the rolled material S is large. It can be used in any case.
