【産業上の利用分野】[Industrial applications]

本考案は、スチールベルト等の横曲がり精度の厳しい鋼帯の横曲り変形量(キ ャンバー値)を測定する装置の改良に関する。 The present invention relates to an improvement of a device for measuring a lateral bending deformation amount (Cumber value) of a steel strip such as a steel belt having a high lateral bending accuracy.

【0002】 ベルトコンベアや、製菓用ベーキングライン等に使用されるスチールベルト材 は、厚み精度や平坦度もさることながら、鋼帯の長さ方向に対する横曲り精度が 厳しく要求される。これらのスチールベルト材は終端部を溶接され、エンドレス 状態にて使用されるため、鋼帯の横曲りがあるとロールから外れたり、溶接部に 過度の応力がかかることによる溶接部の破断等のトラブルが発生する原因となる からである。 このため、この種の鋼帯は最終の検査ラインにおいて横曲り変形量の測定が行 われ、従来の測定方法は、図4に示すように、平坦な検査台1の2地点イ,ロに おいて水糸ないしピアノ線8を支持し検査台上の鋼帯Sの端縁に沿って張り渡し 、その中央部位においてスケール9をあてがって水糸8と鋼帯の端縁との間の離 隔幅d’を読み取ったうえ、そのキャンバー値、すなわち水糸を支持する2点イ −ロ間の距離Lに対する離隔幅d’の比,(d’/L)を算出する、というもの であった。A steel belt material used for a belt conveyor, a baking line for confectionery, etc. is required to have not only thickness accuracy and flatness but also lateral bending accuracy in the length direction of a steel strip. Since these steel belt materials are welded at the end and used in an endless state, if there is lateral bending of the steel strip, it will come off the roll, or the weld will be broken due to excessive stress on the weld. This will cause troubles. Therefore, the amount of lateral bending deformation of this type of steel strip is measured in the final inspection line, and the conventional measurement method is as shown in FIG. Supporting the water thread or the piano wire 8 and straddling it along the edge of the steel strip S on the inspection table, and applying the scale 9 at the central portion thereof to the space between the water thread 8 and the edge of the steel strip. After reading the width d ', the camber value, that is, the ratio of the separation width d'to the distance L between the two-point air supporting the water thread, (d' / L), was calculated. .

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、この方法では、水糸8を長い検査台上の2点で支持し張り渡し た状態のもとで、中央部における水糸と鋼帯縁線の離隔幅d’を測定しなければ ならず、検査員が3名必要であるばかりでなく、その測定作業には水糸の緩みや 、スケールの読取り誤差等が付随するため、測定精度が悪く、信頼性に乏しいも のであった。しかも長い検査ラインを行き来することは、足元の危険のみならず 、鋼帯のエッジに触れることによる災害発生の危険もあった。 本考案はこれらの課題を解決し、測定に人手を掛けず、検査作業の安全を確保 しつつ、能率よく高精度の測定を行おうとするものである。 However, in this method, the separation width d ′ between the water thread and the steel strip edge line in the central portion must be measured under the condition that the water thread 8 is supported and stretched at two points on a long inspection table. In addition, not only three inspectors were required, but the measurement work involved loosening of the water thread, scale reading errors, etc., resulting in poor measurement accuracy and poor reliability. Moreover, traveling back and forth along a long inspection line was not only a danger to the feet, but also a risk of accidents caused by touching the edge of the steel strip. The present invention intends to solve these problems, to perform measurement with high efficiency and high accuracy while ensuring the safety of inspection work without manpower for measurement.

【作用】[Action]

図1は、本考案装置の測定原理を示すブロック図である。検査台1上には、 その台上に載置される鋼帯Sの進行方向に対してほぼ平行な向きの直線上に位置 する3つの測定基点a,b,およびcが等間隔に設定されている。 各測定基点a,b,およびcには、それぞれの基点から検査台1上の被測定鋼 帯Sの端縁Seまでの距離A,B,およびCを検出するための検出装置2(2a ,2b,2c)が配置されている。 なお、両端に位置する測定基点aとcの間の離隔距離Lは、検査精度の点から 、できるだけ長く、検査台一杯に設定することが望ましい。 FIG. 1 is a block diagram showing the measurement principle of the device of the present invention. On the inspection table 1, three measurement base points a, b, and c located on a straight line in a direction substantially parallel to the traveling direction of the steel strip S placed on the inspection table 1 are set at equal intervals. ing. At each of the measurement base points a, b, and c, there is a detector 2 (2a, 2a, 2a, 2c) for detecting the distances A, B, and C from the respective base points to the edge Se of the steel strip S to be measured on the inspection table 1. 2b, 2c) are arranged. In addition, it is desirable that the separation distance L between the measurement base points a and c located at both ends be set as long as possible and set to the full extent of the inspection table in terms of inspection accuracy.

【0006】 検査台1上に送り込まれた鋼帯Sの横曲りの測定は、検査員が、検出装置2a ,2b,2cのそれぞれを遠隔操作することにより行われ、遠隔操作される検出 装置2a,2b,2cにより検出される検出信号A,BおよびCは演算装置3に 入力され、前記〔I〕式の演算が実行される。 その演算結果である横曲り変形量は、mm/m単位の数値(キャンバー値)と して表示装置4に表示され、許容基準を満足するか否かが判定される。演算結果 はプリンター5で検査記録として直接検査日誌に記録してもよい。The lateral bending of the steel strip S sent onto the inspection table 1 is measured by an inspector by remotely operating each of the detection devices 2a, 2b, 2c, and the remotely operated detection device 2a. , 2b, 2c, the detection signals A, B and C are input to the arithmetic unit 3 and the arithmetic operation of the formula [I] is executed. The lateral bending deformation amount as the calculation result is displayed on the display device 4 as a numerical value (camber value) in mm / m unit, and it is determined whether or not the acceptance criterion is satisfied. The calculation result may be directly recorded in the inspection diary by the printer 5 as an inspection record.

【実施例】【Example】

本考案装置の実施例について図面を参照して説明する。 図2は、検査台1に設定された測定基点a(b,c)の各部位に、被測定鋼帯 Sの進行方向(紙面に垂直)に対し直角の向きの溝11を検査台1に形設し、そ の溝11内に磁気を利用した位置検出装置2を設けて、基準点a(b,c)から 鋼帯Sの端縁Seまでの距離A(B,C)を検出するようにした例を示している 。 その位置検出装置2は、エアーシリンダ21,そのピストンロッド22に取付 けられた接触子23,ピストンロッド22の進退移行路に沿って配置されたマグ ネットスケール25,および接触子23に取着され、マグネットスケール25に 接触している検出ヘッド24等で構成されている。 An embodiment of the device of the present invention will be described with reference to the drawings. FIG. 2 shows that the inspection base 1 is provided with grooves 11 at right angles to the traveling direction of the steel strip S to be measured (perpendicular to the paper surface) at each part of the measurement base point a (b, c) set on the inspection base 1. A position detecting device 2 using magnetism is provided in the groove 11 to detect the distance A (B, C) from the reference point a (b, c) to the edge Se of the steel strip S. Here is an example. The position detecting device 2 is attached to the air cylinder 21, a contactor 23 attached to the piston rod 22, a magnet scale 25 arranged along the forward / backward transition path of the piston rod 22, and the contactor 23. The detection head 24 is in contact with the magnet scale 25.

【0008】 エアシリンダ21は検査員により遠隔操作され、そのピストンロッド22に取 着けられている接触子23は、測定基点a(b,c)から鋼帯Sに向かって、そ の端縁Seまで移動する。接触子23の下部に固定されている検出ヘッド24は 接触子23と共に、マグネットスケール25上をスライドして移動する。 これにより、接触子23の移動量、すなわち測定基点a(b,c)から鋼帯S の端縁Seまでの距離A(B,C)が精密に検出される。その検出信号は演算装 置3に入力され、前記〔I〕式の演算が行われ、演算結果はキャンバー値として 瞬時に表示装置4に表示することができる。The air cylinder 21 is remotely operated by an inspector, and the contact 23 attached to the piston rod 22 of the air cylinder 21 is moved from the measurement base point a (b, c) toward the steel strip S, and its edge Se is separated. Move up to. The detection head 24 fixed to the lower portion of the contact 23 slides on the magnet scale 25 together with the contact 23. As a result, the amount of movement of the contact 23, that is, the distance A (B, C) from the measurement base point a (b, c) to the edge Se of the steel strip S 1 is accurately detected. The detection signal is input to the arithmetic unit 3 to perform the arithmetic operation of the formula [I], and the arithmetic result can be instantly displayed on the display device 4 as a camber value.

【0009】 スチールベルト材の横曲り変形量の測定は、鋼帯長さ約100m毎に実施され る。前記図4に示した従来の測定方法による場合、1回の測定に約2分を要して いるが、これに対し、上記測定装置による1回の測定に要する時間は約10秒以 下である。 しかも、従来の測定方法では前述のように3名の検査員を必要とするのに対し 、1名の検査員ですみ、従来法との差異は歴然である。The amount of lateral bending deformation of the steel belt material is measured every about 100 m of the strip length. In the case of the conventional measurement method shown in FIG. 4, it takes about 2 minutes for one measurement, whereas the time required for one measurement with the above-mentioned measuring device is about 10 seconds or less. is there. Moreover, while the conventional measurement method requires three inspectors as described above, only one inspector is required, and the difference from the conventional method is obvious.

【0010】 前記図2では、測定基点から鋼帯の端縁までの距離の検出にマグネットスケー ルを利用した例を示したが、その検出手段はこれに限定されず、種々のものを使 用することができ、例えば図3に示すように、検査台1に形設した溝11内に、 発光器27を設置すると共に、その上方にセンサカメラ28を対向設置しておき 、発光器27の投光に対する被測定鋼帯Sによる遮蔽幅の広狭から鋼帯の端縁S eと測定基点a(b,c)の間の距離を検出する構成とすることもできる。その 検出信号の処理および表示、記録等は前記と同様に行われる。この場合は、図2 の検出装置における接触子23は不要となり、従って鋼帯を走行させながら測定 することも可能である。FIG. 2 shows an example in which a magnet scale is used to detect the distance from the measurement base point to the edge of the steel strip, but the detection means is not limited to this and various types can be used. For example, as shown in FIG. 3, the light emitter 27 is installed in the groove 11 formed in the inspection table 1 and the sensor camera 28 is installed above it so as to face the light emitter 27. The distance between the edge S e of the steel strip and the measurement base point a (b, c) can be detected from the width of the shielding width of the measured steel strip S against the light projection. Processing, display, recording, etc. of the detection signal are performed in the same manner as described above. In this case, the contactor 23 in the detection device of FIG. 2 is not necessary, and therefore, it is possible to measure while the steel strip is running.

【考案の効果】[Effect of the device]

本考案によれば、従来3名の検査員を必要としていたスチールベルト材の横曲 り変形量の測定を1名の検査員で行うことができ、かつ従来のように長い検査ラ インを行き来する必要もなく、検査作業に付随する危険は完全に解消される。 しかも、検査に要する時間は著しく短縮され、検査作業能率が大幅に改善され るのみならず、高精度の測定が確保されることにより、スチールベルト材の形状 品質に対する信頼性も高められる。 According to the present invention, one inspector can measure the amount of lateral bending deformation of the steel belt material, which conventionally required three inspectors, and can traverse a long inspection line as before. The risk associated with inspection work is completely eliminated. Moreover, not only the inspection time is significantly shortened, the inspection work efficiency is greatly improved, but also high-precision measurement is ensured, so that the reliability of the shape quality of the steel belt material is enhanced.
