Description

本発明は、鉄鋼分野における鋼帯コイルを巻き戻して処理を行うラインにおいて、ペイオフリールに該コイルを装着するに当たり、該ペイオフリールのマンドレルの幅方向中心と該コイルの幅方向中心を合わせて、自動で装着する鋼帯コイルの幅方向調芯方法および装置に関する。   The present invention is a line for rewinding a steel strip coil in the steel field, and when mounting the coil on a payoff reel, the width direction center of the mandrel of the payoff reel and the width direction center of the coil are matched, The present invention relates to a width direction alignment method and apparatus for steel strip coils to be automatically mounted.

ペイオフリールのマンドレルに鋼帯コイルを装着するに当たり、幅方向の調芯を行う代表的な方法は、例えば特許文献1に示されているように、コイルカーの走行方向に直交するように該コイルの端面検出器(例えばフォトスイッチ等)を設置し、さらに該コイルカーに走行位置検出器(例えばアブソリュートエンコーダ、またはパルスジェネレータ等)を設置し、該コイルの両端の端面位置を前記2つの検出器を用いて測定し、その測定値から該コイル幅方向中心位置を演算し、該コイル幅方向中心位置と前記ペイオフリールのマンドレル幅方向中心位置とを一致させるように該コイルカーの停止位置を決定するものであった。   When mounting a steel strip coil on a payoff reel mandrel, a typical method for performing alignment in the width direction is, for example, as shown in Patent Document 1, in which the coil is perpendicular to the traveling direction of the coil car. An end face detector (for example, a photo switch) is installed, a travel position detector (for example, an absolute encoder, a pulse generator, etc.) is further installed in the coil car, and the end faces at both ends of the coil are used for the two detectors. The coil width direction center position is calculated from the measured value, and the coil car stop position is determined so that the coil width direction center position matches the mandrel width direction center position of the payoff reel. there were.

また、マンドレルにコイルを装着する際にペイオフリールを移動させて調整が可能な設備において、特許文献2に示されているように、該コイルの端面に対向して配置した距離検出器(例えば超音波距離計、またはレーザ距離計等)で測定した前記端面までの距離と該コイルの幅寸法に基づいて予め設定した基準移動距離との差によって前記ペイオフリールの移動距離を補正して該コイル幅方向を調芯する方法、または、特許文献3に示されているように、ペイオフリールのマンドレルに鋼帯コイルの端面検出器を設置することにより、該ペイオフリールに設けられた位置検出器で測定された移動距離から端面位置を特定し、その測定値から該コイル幅方向中心位置を演算によって求め、その演算結果に基づいて該ペイオフリールを移動させて該コイル幅方向を調芯する方法などが提案されている。   Further, in a facility that can be adjusted by moving a payoff reel when a coil is mounted on a mandrel, as shown in Patent Document 2, a distance detector (for example, a The coil width by correcting the movement distance of the payoff reel by the difference between the distance to the end face measured by a sonic distance meter or a laser distance meter and a reference movement distance set in advance based on the width dimension of the coil. The method of aligning the direction or, as shown in Patent Document 3, by installing the end face detector of the steel strip coil on the mandrel of the payoff reel, and measuring with the position detector provided on the payoff reel The end face position is specified from the measured moving distance, the center position in the coil width direction is obtained by calculation from the measured value, and the payoff reel is moved based on the calculation result. A method of core regulates the coil width direction is proposed.

しかし、上述の従来技術では、以下のような課題があった。
一般に、巻き戻して処理を行う工程に供するためスキッド上に準備された鋼帯コイルは、コイルカーによって持ち上げられ、ラインに運搬される。前記従来の方法ではいずれも、該コイルの昇降を該コイルカーの位置制御によって自動で行うため、該コイルの積載位置が該コイルカーの幅方向中心から外れることがあり、コイルカーのコイル積載面積が小さいため、マンドレルに該コイルが装着されていない状態では該コイルを転倒させる危険性があった。そのため、人間またはセンサによりスキッド上のコイルの位置を常に監視していなければならないという問題があった。
However, the above-described conventional techniques have the following problems.
In general, a steel strip coil prepared on a skid for use in a process of unwinding and processing is lifted by a coil car and transported to a line. In any of the conventional methods, since the coil is automatically moved up and down by position control of the coil car, the coil loading position may deviate from the center in the width direction of the coil car, and the coil loading area of the coil car is small. In the state where the coil is not attached to the mandrel, there is a risk that the coil may fall down. Therefore, there has been a problem that the position of the coil on the skid must be constantly monitored by a person or a sensor.

また、前記鋼帯コイルの転倒が起こらない場合でも、該コイルが前記コイルカーの後ろ側すなわち装着するマンドレルの先端側(該マンドレル駆動部と反対側)に片寄って積載された場合には、該マンドレルの幅方向に調芯する課程において、該コイルカーが駆動部側ストローク限まで幅方向に移動しても、鋼帯コイルの幅方向中心がマンドレル幅中心に至らず幅方向のストローク不足になるため、該コイルを一旦マンドレルに授け、再び該コイルカーに積載しなおしてマンドレル幅中央まで装着しなおす必要が生じるという問題があった。   Further, even when the steel strip coil does not fall down, if the coil is loaded on the rear side of the coil car, that is, on the tip side of the mandrel to be mounted (opposite side of the mandrel driving unit), the mandrel In the course of aligning in the width direction, even if the coil car moves in the width direction to the drive unit side stroke limit, the width direction center of the steel strip coil does not reach the mandrel width center, and the stroke in the width direction becomes insufficient. There is a problem in that it is necessary to transfer the coil to the mandrel, load it again on the coil car, and mount it again to the center of the mandrel width.

また、ペイオフリールを移動させて鋼帯コイルの幅方向の調芯を行う場合には、通板前に該ペイオフリールをセンタリングするかまたは先行材の幅方向中心との位置合わせをする必要があり、段取りに時間がかかってサイクルタイムが増加するという問題がある。   In addition, when moving the payoff reel and performing alignment in the width direction of the steel strip coil, it is necessary to center the payoff reel before threading or align with the center in the width direction of the preceding material, There is a problem that the setup time takes time and the cycle time increases.

上記課題を解決するために、鋭意検討した結果、以下の構成を究明した。
(1)鋼帯コイルを巻き戻して処理を行うラインにおいて、ペイオフリールに鋼帯コイルをコイルカーにより装着するに当たり、予めコイルスキッド上に置かれている鋼帯コイルの幅方向位置を検出し、その測定結果に基づいて前記コイルカーの幅方向中心位置が前記コイルの幅方向中心位置と一致するように前記コイルカーを停止させて前記コイルを上昇させ、その後、ラインに固定されたペイオフリールのマンドレルの幅方向中心位置と前記コイルカーの幅方向中心位置を一致させ、鋼帯コイルをペイオフリールのマンドレルに装着することを特徴とするコイルの幅方向調芯方法。
(2)鋼帯コイルを巻き戻して処理を行うラインに配置され、ペイオフリールに鋼帯コイルをコイルカーにより装着する装置であって、該装置は前記コイルカーの幅方向中心位置検出センサと、コイルスキッド上に置かれている鋼帯コイルの幅方向位置を検出するためのセンサと、を具備し、さらに前記コイルカーをコイルスキッド側からペイオフリールのマンドレルの幅方向中心位置まで移動させる手段を有することを特徴とするコイルの幅方向調芯装置。
As a result of intensive studies to solve the above-mentioned problems, the following configurations have been investigated.
(1) In the line where the steel strip coil is rewound and processed, when the steel strip coil is mounted on the payoff reel by a coil car, the width direction position of the steel strip coil previously placed on the coil skid is detected, Based on the measurement result, the coil car is stopped and the coil is raised so that the center position in the width direction of the coil car matches the center position in the width direction of the coil, and then the width of the mandrel of the payoff reel fixed to the line A width direction alignment method for a coil, wherein the center position in the direction is matched with the center position in the width direction of the coil car, and the steel strip coil is mounted on a mandrel of a payoff reel.
(2) An apparatus for mounting a steel strip coil on a payoff reel by a coil car, which is disposed in a line for rewinding the steel strip coil, and comprising a sensor for detecting the center position in the width direction of the coil car, and a coil skid. A sensor for detecting the position in the width direction of the steel strip coil placed thereon, and further comprising means for moving the coil car from the coil skid side to the center position in the width direction of the mandrel of the payoff reel. A coil width alignment device as a feature.

本発明によれば、ペイオフリール近傍に、該ペイオフリールのマンドレルと鋼帯コイルの幅方向を調芯するための該コイルの端面を検出するセンサ等を設置する必要がなく、設備上の制約が大幅に緩和される。
また、常にコイルカーの幅方向中心に鋼帯コイルが積載されるので、鋼帯コイルを持ち上げる際の該コイルの転倒の危険性がなくなるとともに、ペイオフリールのマンドレルに装着する過程で、該コイルの中心位置が適合しないことで積載しなおす等の生産のロスタイムの発生がなくなる。
According to the present invention, there is no need to install a sensor or the like for detecting the end face of the coil for aligning the width direction of the mandrel of the payoff reel and the steel strip coil in the vicinity of the payoff reel. It is greatly eased.
In addition, since the steel strip coil is always loaded at the center of the width direction of the coil car, there is no risk of the coil falling when the steel strip coil is lifted, and the center of the coil is mounted in the process of mounting on the mandrel of the payoff reel. Loss of production time such as re-loading is eliminated because the position does not match.

本発明に係る鋼帯コイルをペイオフリールに装着する工程の概要を示す模式図である。It is a schematic diagram which shows the outline | summary of the process of mounting | wearing the payoff reel with the steel strip coil which concerns on this invention. 本発明の実施手順を示す説明図である。It is explanatory drawing which shows the implementation procedure of this invention.

以下、本発明の実施形態を図面を用いて具体的に説明する。
通常、鋼帯コイルを巻き戻して処理を行うラインにおいては、図1に示すように、予めスキッド3上に準備された鋼帯コイル1をコイルカー2でラインまで運搬し、ペイオフリール5のマンドレル6に鋼帯コイル1を装着することが行われる。この際、鋼帯コイル1の幅方向中心1cと該マンドレル6の幅方向中心6c(ラインセンター(LC)と一致)を一致させる必要がある。
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
Normally, in a line where the steel strip coil is rewound and processed, as shown in FIG. 1, the steel strip coil 1 prepared in advance on the skid 3 is transported to the line by the coil car 2, and the mandrel 6 of the payoff reel 5. The steel strip coil 1 is attached to the battery. At this time, it is necessary to make the width direction center 1c of the steel strip coil 1 coincide with the width direction center 6c of the mandrel 6 (coincidence with the line center (LC)).

本発明では、まず、スキッド3上に置かれた鋼帯コイル1の幅方向位置を位置検出センサ4により検出し、スキッド3の幅方向中心3cと該コイル1の幅方向中心1cとのずれ量x(図2(a))を計測する。その手段はいかなるものでも良いが、図1に示すように、例えばレーザエリアセンサ、フォトエリアセンサ等の位置検出センサ4をスキッド3に設置し、これにより測定を行うのが好都合である。   In the present invention, first, the position in the width direction of the steel strip coil 1 placed on the skid 3 is detected by the position detection sensor 4, and the amount of deviation between the width direction center 3c of the skid 3 and the width direction center 1c of the coil 1 is detected. x (FIG. 2 (a)) is measured. Any means may be used, but as shown in FIG. 1, it is convenient to install a position detection sensor 4 such as a laser area sensor or a photo area sensor on the skid 3 and thereby perform measurement.

次に、鋼帯コイル1をラインまで運搬するためのコイルカー2をスキッド3の下部に配置して、鋼帯コイル1を上昇させ、ペイオフリール5のマンドレル6の高さと鋼帯コイル1の中央空洞の高さを合わせる。この際、コイルカー2の幅方向中心位置2cを上記で計測したずれ量xだけスキッド3の幅方向中心位置3cからずらし、鋼帯コイル1の幅方向中心1cとコイルカー2の幅方向中心2cを一致させた状態で、鋼帯コイル1を上昇させる(図2(b))。コイルカーの位置制御は従来技術と同様に、演算装置(例えばプログラマブルロジックコンピュータ、シーケンサ等)と該コイルカーに設置した位置検出センサ(例えばアブソリュートエンコーダ、パルスジェネレータ等)によって行うことが好ましい。   Next, the coil car 2 for transporting the steel strip coil 1 to the line is arranged at the lower part of the skid 3 to raise the steel strip coil 1, the height of the mandrel 6 of the payoff reel 5 and the central cavity of the steel strip coil 1. Adjust the height. At this time, the center position 2c in the width direction of the coil car 2 is shifted from the center position 3c in the width direction of the skid 3 by the displacement amount x measured above, and the width direction center 1c of the steel strip coil 1 and the width direction center 2c of the coil car 2 coincide. In this state, the steel strip coil 1 is raised (FIG. 2 (b)). As in the prior art, the position control of the coil car is preferably performed by an arithmetic unit (for example, a programmable logic computer, a sequencer, etc.) and a position detection sensor (for example, an absolute encoder, a pulse generator, etc.) installed in the coil car.

次に、コイルカー2を前記ラインに移動し(図2(c))、コイルカー2の幅方向中心2cと前記ペイオフリール5のマンドレル6の幅方向中心6c(ラインセンター(LC)に一致)に一致させて停止させ、鋼帯コイル1をマンドレル6に装着する(図2(d))。従来技術では、この際にセンサで鋼帯コイルの端面位置を検出して停止位置を決定させる必要があったが、本発明ではコイルカーの中心とコイルの幅方向中心を一致させているので、該コイルカーの位置制御だけで、コイルの幅に関わらず、マンドレルの幅方向中心(ラインセンター(LC)に一致)と該コイルの幅方向中心を一致させることが可能である。   Next, the coil car 2 is moved to the line (FIG. 2C) and coincides with the width direction center 2c of the coil car 2 and the width direction center 6c of the mandrel 6 of the payoff reel 5 (matches the line center (LC)). The steel strip coil 1 is mounted on the mandrel 6 (FIG. 2D). In the prior art, at this time, it was necessary to detect the end face position of the steel strip coil with a sensor and determine the stop position. However, in the present invention, the center of the coil car and the center in the width direction of the coil are matched. By only controlling the position of the coil car, it is possible to match the width direction center of the mandrel (matching the line center (LC)) and the width direction center of the coil regardless of the width of the coil.

以上、上記手順を繰り返すことにより、鋼帯コイルの幅サイズが種々混在している場合においても、巻き戻し工程に送られてきたコイルをペイオフリールのマンドレルに自動的かつ正確に装着することができる。   As described above, by repeating the above procedure, the coil sent to the rewinding process can be automatically and accurately mounted on the mandrel of the payoff reel even when the steel strip coil has various width sizes. .
