【発明の属する技術分野】
本発明は、条材端面状態検出装置及び検出方法であり、特に条材端面の状態に応じて従動するローラと、ローラの従動する量を高精度に測定して、端面に発生したバリ等の状態を数値化し、比較判定して条材端面状態を監視するシステムに関する。
【0002】
【従来の技術】
従来、条材端面の状態を高精度に測定、監視する技術は確立されておらず、熟練作業者による目視や感覚で監視が行なっている。
【0003】
【発明が解決しようとする課題】
条材は変圧器等の巻線に使用される事が多い。この時、製品の特性上、図12に示すように、条材と条材との間に層間紙(絶縁紙)を挟み込んで巻き、条材同士の絶縁を図りながら巻く必要がある。この時、条材端面にバリ等が有り、層間紙を傷つけ、条材同士が接触すると、図13に示すように、条材が短絡し、正規の特性を得られる無くなる。この様な不具合が発生した巻線は、修正が大変困難あり、多くの工数、費用が発生する為、端面のバリ有無は非常に重要な項目である。しかし、従来、端面状態の監視は、熟練作業者による目視と感覚で行なっているのが現状である。そのため、次の様な問題が有り、それらを解決する必要がある。問題点として、監視が作業者により目視と感覚である為、感覚の違いから、端面監視(合否判定)に誤差が生じる。作業に熟練技術が必要である為、人材の育成が必要である。通常、条材はフープ状に巻かれているものが一般的である為、端面の監視は、かなりの連続作業となり、作業者の疲労度が大きい。そのため、作業者の集中力が欠け、端面監視(合否判定)に誤判定が発生する可能性がある。条材の端面は、左右の上面側と下面側とがあるため、複数の作業者による監視が必要である。そのため、多くの工数が必要となり、材料が高価なものとなっている。
【0004】
本発明は、従来の問題点を解決するものであり、条材端面の状態を高精度に測定し、それらを比較判定し条材端面を監視することで、高精度、且つ、安定した端面監視を可能とする条材端面状態検出装置及び検出方法を提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明は、条材の端面に発生したバリ等の状態を搬送しながら検出する装置において、前記条材を搬送する搬送部と、搬送中の条材の端面を押圧する第1のローラ及び搬送面内で搬送方向と直交する方向への前記第1のローラの移動距離を測定する第1の測定部材を有する第1のローラ本体部と、該第1のローラ本体部より搬送方向下流に設置され、搬送中の条材の端面を押圧する第2のローラ及び搬送面内で搬送方向と直交する方向への前記第2のローラの移動距離を測定する第2の測定部材を有する第2のローラ本体部とを備え、前記第2のローラの条材押圧面の条材端面に対する傾斜角度は、前記第1のローラの条材押圧面の条材端面に対する傾斜角度と相違する条材端面状態検出装置である。
【0006】
また、本発明は、一方のローラ本体部のローラは、条材押圧面が条材端面に対して平行である平ローラであり、他方のローラ本体部のローラは、条材押圧面が条材端面に対して傾斜しているVローラである条材端面状態検出装置である。
【0007】
そして、本発明は、搬送中の条材の端面に発生したバリ等の状態を検出する方法において、条材押圧面が条材端面に対して第1の傾斜角度をなす第1のローラで条材端面を押圧して搬送面内で搬送方向に直交する方向への第1のローラの移動距離を測定し、次に、第1のローラより搬送方向下流に設置され、条材押圧面が条材端面に対して前記第1の傾斜角度と相違する第2の傾斜角度をなす第2のローラで条材端面を押圧して第2のローラの移動距離を測定し、測定した第1の移動距離と第2の移動距離とを比較して条材端面の状態を検出する条材端面状態検出方法である。
【0008】
【発明の実施の形態】
本発明の実施の形態を説明する。
本発明の条材端面状態検出装置及び検出方法の実施例について、図1〜図11を用いて説明する。図1は、実施例の条材端面状態検出装置の測定部材の鳥瞰図である。図2は、実施例の条材端面状態検出装置の測定部材の平面図及び側面図である。図3は、実施例の条材端面状態検出装置のVローラの変位量の説明図である。図4は、実施例における条材端面に変化がない時のVローラの変位量の説明図である。図5は、実施例における条材端面に変化が生じた時のVローラの変位量の説明図である。図6は、実施例における条材端面に変化が生じた時のVローラの第2の変位量の説明図である。図7は、実施例における片方を平ローラにした時の平ローラとVローラの変位量の説明図である。図8は、実施例における幅方向を平ローラで測定するポイントの説明図である。図9は、実施例における図8の測定ポイントがVローラの測定ポイントに移動した状態の説明図である。図10は、実施例における条材の両端面を測定しようとした時の測定部材の平面図である。図11は、実施例におけるVローラ、平ローラの従動量を増幅させる時の説明図である。
【0009】
実施例1を説明する。本実施例の条材端面状態検出装置は、条材を搬送する搬送部と、搬送中の条材の端面を押圧する第1のローラ及び搬送面内で搬送方向と直交する方向への第1のローラの移動距離を測定する第1の測定部材を有する第1のローラ本体部と、第1のローラ本体部より搬送方向下流に設置され、搬送中の条材の端面を押圧する第2のローラ及び搬送面内で搬送方向と直交する方向への第2のローラの移動距離を測定する第2の測定部材を有する第2のローラ本体部とを備え、第2のローラの条材押圧面の条材端面に対する傾斜角度は、第1のローラの条材押圧面の条材端面に対する傾斜角度と相違する。
【0010】
実施例1を具体的に説明すると、本実施例における端面の状態を検出する条材1の端面は、圧延スリッタ等で所定の幅に切断する際、端面にバリが発生する。例えば変圧器で条材1を使用する場合、コイル16の材料として使用されるが、この時、条材1は1巻目と2巻目との絶縁を図りながら巻く必要がある。その為、図12の様に、条材1の間に絶縁物10を入れながらコイル16を製作している。しかし、上記で述べた様な端面にバリが発生していると、図13(a)(b)の様に、バリが絶縁物を傷つけ、条材1同士が短絡状態となり、製品の特性が得られなくなるという不具合を発生させる。
【0011】
そこで、実施例1の条材端面状態検出装置は、条材1の端面に、Vローラ6、7、又は、平ローラ8を押し当て、端面の状態に応じて従動させる事で、条材端面の状態を高精度に測定し、監視するシステムであり、図面を用いて説明する。その例を図1に示す。条材1の端面に、水平方向に揺動するスライドベース14上に設けたVローラ6、7をばね等の力で押し当てる。Vローラ6、7は、端面の状態によって搬送平面内で搬送(送り)方向に直交する方向に従動する。
【0012】
実施例1における変位(移動)量について、図3(a)(b)を用いて説明する。端面が直角になっている条材3を基準と考えた時、端面にエッジが発生した条材4にVローラ6、7を押し当てた時は、バリの量だけ外側に押される。また、正常端面処理された条材2にVローラ6、7を押し当てた時は、バリの量だけ内側に押され、それぞれ、基準状態に対して変位量A、変位量Bの様な差が生じる。この変位量を変位センサや測長センサ等により測定する。そして、この変位量を比較することにより、条材端面の状態を検出することができる。なお、比較する際は、搬送スピードを考慮し、同じ個所の変位量を比較する。
【0013】
実施例1の測長センサを取り付けた時の状態について、図2、図4〜図6を用いて説明する。図2に示すように、材料の送り方向に対し入口側に入口側Vローラ6を、出口側に出口側Vローラ7をそれぞれ平行に設ける。そして、条材1の端面状態が入口側Vローラ6部と、出口側Vローラ7部とで同様の状態の場合は、図4の変位量Cに示す様に変位量の差は発生しない。条材1を送り方向に送った時、条材1端面状態が、入口側Vローラ6部と、出口側Vローラ7部とで異なると、Vローラ6、7が図5、図6に示すような変位量D、変位量Eを発生させる。この変位量を制御機器等に数値で取り込む事により、条材1端面の状態を監視し、必要であれば送りを停止させる。しかし、この時、条材1の端面に押し当てるローラがVローラ6、7同士の場合、急な端面状態の変化は検出できるが、徐々に変化する端面状態や、条材1の幅方向による変化の対応は出来ない言う問題がある。この問題に関しては、図7に示すように、端面に押し当てるローラの片方を平ローラ8にする。測定方法としては、先ず、平ローラ8で条材1の幅方向の変位量を測定する(図8)。タイマ等で時間差を設け、平ローラ8が測定したポイントがVローラ7に到達した時点でVローラ7の変位量を測定する(図9)。Vローラ7の変位量は、平ローラで測定した幅方向に対する変位量を考慮し、幅方向が大きく変位した時は、Vローラ7の変位量をその分マイナスし、幅方向が小さく変位した時は、Vローラ7の変位量をその分プラスする。この事により、上記で問題となった、幅方向に対した条材1の状態の測定と、幅方向の変化に対応した条材1の端面状態の測定が可能となる。本測定部材の一例の平面図を図10に示す。
【0014】
なお、条材1の板厚が薄い等により、押し当てたVローラ6、7及び、平ローラ8の変位量が少なく測定しづらい場合は、図11に示すような、測定ドグ18を軸17を中心に謡動する様な構造にし、測定部で変位量を増大させることで確実に測定が出来る様になり、変位量が少ない場合でも条材1端面の状態を監視できるようになる。
【0015】
このように、条材端面にVローラ及び平ローラを押し当て、端面状態に応じて従動させ、その変位量を制御機器に取り込む事で、数値による条材端面状態の監視が可能となり、条材の安定した品質管理と、安価な材料の提供が可能となる。なお、Vローラ及び平ローラの代りに、条材押圧面の条材端面に対する傾斜角度が相違する2つのローラを使用することも可能である。
【0016】
上記実施例で説明したように、本発明によれば、条材の端面に、条材端面の状態と従動するローラ等を接触させ、そのローラの従動量を高精度に測定する構造と、これらの従動するローラを複数個使用し、個々の従動変化量を測定、比較判定する事で、端面の状態を監視するシステムとすることができる。
【0017】
【発明の効果】
本発明によれば、条材端面の状態を高精度に測定し、それらを比較判定し条材端面を監視することで、高精度、且つ、安定した端面監視を可能とする条材端面状態検出装置及び検出方法を得ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention is a strip end face state detection device and a detection method, and in particular, a roller that is driven according to the state of the strip end face, and a driven amount of the roller is measured with high precision, and burrs or the like generated on the end face are measured. The present invention relates to a system for quantifying a state, comparing and judging the state, and monitoring a state of a strip end face.
[0002]
[Prior art]
Conventionally, a technique for measuring and monitoring the state of the end face of a strip material with high accuracy has not been established, and monitoring is performed visually or by a skilled worker.
[0003]
[Problems to be solved by the invention]
Strips are often used for windings such as transformers. At this time, due to the characteristics of the product, as shown in FIG. 12, it is necessary to sandwich the interlayer paper (insulating paper) between the strips and wind them, and wind them while insulating the strips. At this time, if there is a burr or the like on the end surface of the strip material and the interlayer paper is damaged and the strip materials come into contact with each other, the strip material is short-circuited as shown in FIG. Since the winding in which such a defect has occurred is very difficult to correct and requires a lot of man-hours and costs, the presence or absence of burrs on the end face is a very important item. However, monitoring of the state of the end face has conventionally been performed visually and by a skilled worker. Therefore, there are the following problems, which need to be solved. As a problem, since monitoring is visually and sensibly performed by an operator, an error occurs in end surface monitoring (pass / fail judgment) due to a difference in sensation. Since skilled skills are required for the work, human resource development is required. Usually, since the strip is generally wound in a hoop shape, monitoring of the end face is a considerably continuous operation, and the degree of fatigue of the worker is large. Therefore, there is a possibility that the concentration of the worker is lacking and an erroneous determination occurs in the end face monitoring (pass / fail determination). Since the end surface of the strip has left and right upper and lower surfaces, monitoring by a plurality of operators is required. Therefore, many man-hours are required, and the material is expensive.
[0004]
The present invention solves the conventional problems, and measures the state of the end face of the strip with high accuracy, compares and judges them, and monitors the end face of the strip, thereby achieving high-accuracy and stable end face monitoring. It is an object of the present invention to provide a strip end face state detecting device and a detecting method which enable the above.
[0005]
[Means for Solving the Problems]
The present invention is directed to an apparatus for detecting a state of burrs or the like generated on an end face of a strip while conveying the strip, a conveyance unit for conveying the strip, a first roller for pressing an end face of the strip being conveyed, and a conveyance unit. A first roller main body having a first measuring member for measuring a moving distance of the first roller in a direction orthogonal to a conveying direction in a plane; and a first roller main body disposed downstream of the first roller main body in the conveying direction. A second roller for pressing an end surface of the strip being conveyed, and a second measuring member for measuring a moving distance of the second roller in a direction orthogonal to the conveying direction in the conveying surface. A roller body portion, wherein the inclination angle of the second member pressing surface of the second roller with respect to the first member end surface is different from the inclination angle of the first member pressing surface of the second roller with respect to the first member end surface. It is a detection device.
[0006]
Further, according to the present invention, the roller of one roller body is a flat roller having a strip material pressing surface parallel to the strip material end face, and the roller of the other roller body is configured such that the strip material pressing surface is a strip material. It is a strip end face state detection device which is a V roller inclined with respect to the end face.
[0007]
The present invention provides a method for detecting a state of burrs or the like generated on an end face of a strip material being conveyed, wherein the strip pressing surface has a first inclination angle with respect to the strip end face with a first roller. The end surface of the material is pressed to measure the moving distance of the first roller in the direction perpendicular to the conveying direction in the conveying surface, and then the roller is installed downstream of the first roller in the conveying direction. The second roller having a second inclination angle different from the first inclination angle with respect to the material end face presses the strip end face to measure the moving distance of the second roller, and the measured first movement This is a method for detecting the state of the end surface of the strip by comparing the distance with the second moving distance.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described.

FIG. 10 is a plan view of the measuring member when trying to measure both end faces of the strip in the example. FIG. 11 is an explanatory diagram when the driven amount of the V roller and the flat roller in the embodiment is amplified.
[0009]
Example 1 will be described. The strip end face state detecting device according to the present embodiment includes a conveying unit that conveys the strip, a first roller that presses the end face of the strip being conveyed, and a first roller in a direction orthogonal to the conveying direction in the conveying plane. A first roller main body having a first measuring member for measuring the moving distance of the roller, and a second roller installed downstream of the first roller main body in the conveyance direction and pressing an end surface of the strip being conveyed. A roller and a second roller body having a second measuring member for measuring a moving distance of the second roller in a direction perpendicular to the conveying direction in the conveying surface, and a member pressing surface of the second roller. Is different from the inclination angle of the first roller pressing surface of the first roller with respect to the end surface of the first roller.
[0010]
The first embodiment will be described specifically. When the end surface of the strip 1 for detecting the state of the end surface in the present embodiment is cut to a predetermined width by a rolling slitter or the like, burrs are generated on the end surface. For example, when the strip 1 is used in a transformer, it is used as a material of the coil 16. At this time, it is necessary to wind the strip 1 while insulating the first and second turns. Therefore, as shown in FIG. 12, the coil 16 is manufactured while inserting the insulator 10 between the strips 1. However, if burrs are generated on the end face as described above, the burrs damage the insulator, and the strips 1 are short-circuited as shown in FIGS. This causes a problem that it cannot be obtained.
[0011]
Therefore, the strip end face state detecting device according to the first embodiment presses the V roller 6, 7, or the flat roller 8 against the end face of the strip 1 and is driven according to the state of the end face, whereby the strip end face is detected. This is a system for measuring and monitoring the state of the object with high accuracy, and will be described with reference to the drawings. An example is shown in FIG. V rollers 6, 7 provided on a slide base 14 swinging in the horizontal direction are pressed against the end surface of the strip 1 by a force such as a spring. The V rollers 6, 7 are driven in a direction perpendicular to the transport (feed) direction in the transport plane depending on the state of the end surface.
[0012]
The displacement (movement) amount in the first embodiment will be described with reference to FIGS. Assuming that the strip 3 whose end face is at a right angle is considered as a reference, when the V rollers 6 and 7 are pressed against the strip 4 whose edge is generated on the end face, it is pushed outward by the amount of burrs. When the V-rollers 6 and 7 are pressed against the strip 2 having been subjected to the normal end face treatment, the V-rollers 6 and 7 are pressed inward by the amount of burrs, and the difference between the displacement amount A and the displacement amount B with respect to the reference state respectively. Occurs. This displacement is measured by a displacement sensor, a length measuring sensor, or the like. By comparing the displacement amounts, the state of the end face of the strip can be detected. In comparison, the displacement amount at the same location is compared in consideration of the transport speed.
[0013]
A state when the length measuring sensor according to the first embodiment is attached will be described with reference to FIGS. 2 and 4 to 6. As shown in FIG. 2, an inlet-side V-roller 6 is provided on the inlet side and a outlet-side V-roller 7 is provided on the outlet side in parallel with respect to the material feeding direction. When the end surface of the strip 1 is in the same state at the entrance-side V-roller 6 and the exit-side V-roller 7, there is no difference in the amount of displacement as shown by the amount of displacement C in FIG. When the strip 1 is fed in the feed direction, if the end face state of the strip 1 is different between the entrance side V roller 6 part and the exit side V roller 7 part, the V rollers 6, 7 are shown in FIGS. Such displacement amount D and displacement amount E are generated. By taking this displacement amount as a numerical value into a control device or the like, the state of the end surface of the strip 1 is monitored, and the feed is stopped if necessary. However, at this time, when the rollers pressed against the end face of the strip 1 are the V rollers 6 and 7, a sudden change in the end face state can be detected, but the change in the end face state that gradually changes or the width direction of the strip 1 is caused. There is a problem that change cannot be handled. Regarding this problem, as shown in FIG. 7, one of the rollers pressed against the end face is a flat roller 8. As a measuring method, first, the displacement amount of the strip 1 in the width direction is measured by the flat roller 8 (FIG. 8). A time difference is provided by a timer or the like, and the displacement of the V roller 7 is measured when the point measured by the flat roller 8 reaches the V roller 7 (FIG. 9). The displacement amount of the V roller 7 is determined by taking into account the displacement amount in the width direction measured by the flat roller. When the displacement in the width direction is large, the displacement amount of the V roller 7 is reduced by that amount, and when the displacement in the width direction is small. Increases the amount of displacement of the V roller 7 by that amount. This makes it possible to measure the state of the strip 1 in the width direction and the state of the end face of the strip 1 corresponding to the change in the width direction, which are problems as described above. FIG. 10 shows a plan view of an example of the present measurement member.
[0014]
When the displacement of the pressed V rollers 6, 7 and the flat roller 8 is small due to the small thickness of the strip material 1 or the like, and it is difficult to measure, the measuring dog 18 as shown in FIG. , The measurement can be reliably performed by increasing the amount of displacement in the measuring section, and the state of the end surface of the strip 1 can be monitored even when the amount of displacement is small.
[0015]
In this way, the V-roller and the flat roller are pressed against the end surface of the strip, driven according to the end face state, and the displacement amount is taken into the control device, whereby the end state of the strip can be monitored by numerical values. Stable quality control and the provision of inexpensive materials. Instead of the V roller and the flat roller, it is also possible to use two rollers having different inclination angles of the strip pressing surface with respect to the strip end face.
[0016]
As described in the above embodiment, according to the present invention, the end face of the strip is brought into contact with a roller or the like that is driven by the state of the end face of the strip, and a structure for measuring the driven amount of the roller with high accuracy, By using a plurality of driven rollers and measuring, comparing and determining the amount of each driven change, a system for monitoring the state of the end face can be provided.
[0017]
【The invention's effect】
