Description

本発明は、鋼帯処理ラインのリンガーローラーやテンションレベラー他に適用可能なストリップのエッジワイパー装置に関するものである。   The present invention relates to a strip edge wiper device applicable to a ringer roller, a tension leveler, etc. of a steel strip processing line.

この種の装置の第１例として、鋼板エッジの水などを除去するために、鋼板幅の大きさによってそれぞれのエッジにあたるように、複数のエアーノズルが設けられていた。そして、板の形状異常などでノズル退避させたい場合は、エアーシリンダなどで持ち上げていた。 As a first example of this type of apparatus, in order to remove water and the like at the edge of the steel plate, a plurality of air nozzles are provided so as to hit each edge depending on the width of the steel plate. And when it was desired to retreat the nozzle due to an abnormal shape of the plate, it was lifted with an air cylinder or the like.

この種の装置の第２例として、特許文献１のものは次のようなものであった。即ち、
図５に示したように、２本のロールが弾性ウレタンゴムからなり、ロール間にストリップ１を挟んで通過させるとき、ストリップ長端に生じる三角形の隙間７から出てくる液をシールするノズル８が設けられる。ノズルは隙間７に高圧空気を噴射する。ノズル位置を移動できるように、ネジ棒をチエン１２を介してモータ９を回転させ、ネジ棒に搭載されたノズルを移動させる。 As a second example of this type of device, the device disclosed in Patent Document 1 is as follows. That is,
As shown in FIG. 5, when the two rolls are made of elastic urethane rubber and the strip 1 is passed between the rolls, the nozzle 8 seals the liquid coming out of the triangular gap 7 generated at the long end of the strip. Is provided. The nozzle injects high-pressure air into the gap 7. The motor 9 is rotated through the chain 12 so that the nozzle position can be moved, and the nozzle mounted on the screw rod is moved.

また第３例として、特許文献２のものは次のようなものであった。即ち、ストリップの上下にエアーヘッダを設け、これらを板幅方向に移動可能とし、エアーヘッダの位置を検出する装置を設けたものである。   As a third example, the one in Patent Document 2 is as follows. In other words, air headers are provided above and below the strip, and these are movable in the plate width direction, and a device for detecting the position of the air header is provided.

しかしながら、これらの従来の装置ではいずれも大がかりなノズルの駆動装置を必要とする。また、第２、第３例のものでは、ノズルをストリップ幅方向に移動させるので、ストリップの両側にスペースを必要とし、作業者はその部分に近づくことができない。このように、ノズルを直線的に移動させるので、原理的に広い空間が必要であり、駆動エアーシリンダのストロークも長くなる。   However, any of these conventional devices requires a large nozzle drive device. In the second and third examples, since the nozzle is moved in the strip width direction, a space is required on both sides of the strip, and the operator cannot approach that portion. Thus, since the nozzle is moved linearly, a large space is required in principle, and the stroke of the drive air cylinder is also long.

本発明は上記課題を解決し、エアーノズルを必要な時に簡単に退避でき、エアーシリンダなどの駆動装置を使わない装置を提供することを目的とする。   An object of the present invention is to solve the above-mentioned problems and to provide a device that can easily retract an air nozzle when necessary and does not use a driving device such as an air cylinder.

本発明の第１課題解決手段は、鋼帯処理ラインのストリップのエッジ部に付着した水等を除去するものであって、ストリップの上側に間隔を存してストリップ幅方向に沿う水平軸回りに回動自在に支持された平面視矩形のフレームと、該フレームを回動させる操作ハンドルと、前記フレームを回動・固定可能とさせる手段と、前記フレームの上側に固定されてストリップ幅方向に長いエアーヘッダと、該エアーヘッダからストリップ長さ方向に沿って下方に伸び、かつ、ストリップ幅方向に複数対設けられたエアー噴射管と、該噴射管の先端に取り付けられたエアーノズルとを備えたことである。   The first problem-solving means of the present invention is to remove water or the like adhering to the edge portion of the strip of the steel strip processing line, and is disposed around the horizontal axis along the strip width direction with an interval above the strip. A rectangular frame in a plan view supported rotatably, an operation handle for rotating the frame, a means for enabling the frame to be rotated and fixed, and fixed to the upper side of the frame and long in the strip width direction An air header, an air jet pipe extending downward from the air header along the strip length direction and provided in pairs in the strip width direction, and an air nozzle attached to the tip of the jet pipe That is.

本発明の第２課題解決手段は第１課題解決手段に加え、前記フレームを回動、固定させる手段において、第２支柱に円弧状のスリットを設け、前記操作ハンドルに設けた孔と前記スリットを合わせ、ボルトを通し、ナットで締結するようにし、前記フレームの回動範囲を無段階に変更可能としたことである。   According to a second problem solving means of the present invention, in addition to the first problem solving means, in the means for rotating and fixing the frame, the second support column is provided with an arc-shaped slit, and the hole provided in the operation handle and the slit are provided. The bolts are passed through and fastened with nuts, and the rotation range of the frame can be changed steplessly.

以下に本発明の一実施例を図面にもとづき説明する。
図１，２において、本発明は鋼帯処理ラインのストリップＳのエッジ部に付着した水等を除去するものである。その大要は、ストリップの上側に間隔を存してストリップ幅方向に沿う水平軸３の回りに回動自在に支持された平面視矩形の主フレーム１と、該フレームを回動させる操作ハンドル１１と、前記フレームを回動・固定可能とさせる手段１２と、前記フレームの上側に固定されてストリップ幅方向に長いエアーヘッダ５と、該エアーヘッダからストリップ長さ方向に沿って下方に伸び、かつ、ストリップ幅方向に複数対設けられたエアー噴射管６と、該噴射管の先端に取りつけられたエアーノズル７とを備えたものである。 An embodiment of the present invention will be described below with reference to the drawings.
1 and 2, the present invention removes water and the like attached to the edge of the strip S of the steel strip processing line. The main points are a main frame 1 having a rectangular shape in a plan view supported rotatably around a horizontal axis 3 along the strip width direction with a space above the strip, and an operation handle 11 for rotating the frame. And means 12 for enabling the frame to be rotated and fixed; an air header 5 fixed to the upper side of the frame and extending in the strip width direction; and extending downward from the air header along the strip length direction; A plurality of pairs of air jet pipes 6 are provided in the strip width direction, and an air nozzle 7 is attached to the tip of the jet pipe.

平面視矩形の主フレーム１は、その展延面をほぼストリップの上面に平行とし、かつ、矩形の対向２辺（前後辺）をストリップの両端（エッジ）に平行となっている。フレームの対向２辺（前後辺）の中央から水平軸３がストリップ幅方向に延びて設けられ、この水平軸が床から立てられた第１支柱８の上面に軸受を介して回転自在とされる。   The main frame 1 having a rectangular shape in plan view has its extended surface substantially parallel to the upper surface of the strip, and two opposite sides (front and rear sides) of the rectangle are parallel to both ends (edges) of the strip. A horizontal shaft 3 is provided extending in the strip width direction from the center of two opposite sides (front and rear sides) of the frame, and this horizontal shaft is rotatable on the upper surface of the first support column 8 standing from the floor via a bearing. .

主フレーム１の対向２辺（前後辺）の前辺の上側に、門形の副フレーム２が立設され、この上辺中央から中間片４を介して、ハンドル軸１０が板幅方向手前へ延び、その先端に細板状の操作ハンドル１１が設けられる。これによってハンドルを両手で握って右回り、左回りさせると、主フレーム１は水平軸回りに揺動する。   A gate-shaped sub-frame 2 is erected on the upper side of the front side of the two opposite sides (front and rear sides) of the main frame 1, and the handle shaft 10 extends forward from the center of this upper side via the intermediate piece 4 in the plate width direction. A thin plate-like operation handle 11 is provided at the tip. As a result, when the handle is gripped with both hands and rotated clockwise and counterclockwise, the main frame 1 swings around the horizontal axis.

操作ハンドル１１に接近して第２支柱９が床から立設され、これには位置決め孔９ａが２個設けられている。そして、この孔とハンドルに設けた孔とを合わせて、ボルト１２を通して締結する。   The second support column 9 is erected from the floor close to the operation handle 11, and is provided with two positioning holes 9a. And this hole and the hole provided in the handle | steering_wheel are match | combined and it fastens with the volt | bolt 12. FIG.

前記において、板幅の大，中，小に対応してノズル系統（各々ａ，ｂ，ｃで表す）を分ける。機側にある「エッジワイパー操作盤」にＰＢＬ（プッシュボタン・ランプ），「大」，「中」，「小」の操作表示を設ける。各ＰＢＬに対応した系統のノズルからエアーを送る。このため、各系統に電磁弁と、その操作のためのリレー回路が設けられる。電磁弁不良の対策として、各電磁弁に対してバイパスを設ける。各系統に弁と圧力系を設置する。   In the above, nozzle systems (represented by a, b, and c, respectively) are divided corresponding to the large, medium, and small plate widths. PBL (push button / lamp), “Large”, “Medium” and “Small” operation displays are provided on the “Edge Wiper Operation Panel” on the machine side. Air is sent from the nozzle of the system corresponding to each PBL. For this reason, each system is provided with a solenoid valve and a relay circuit for its operation. As a countermeasure against defective solenoid valves, a bypass is provided for each solenoid valve. Install valves and pressure systems in each system.

以上において、作動状態を説明する。図１、２に示すように、実線示のように、板幅「小」に対応したノズル７ｃ，噴射管６ｃ，ヘッダ５ｃに圧縮エアーが供給され、ストリップのエッジ部に付着している水などを吹き飛ばして除去する。板幅が変われば、それに対応したノズル、噴射管、ヘッダに圧縮エアーが供給される。   The operating state will be described above. As shown in FIGS. 1 and 2, compressed air is supplied to the nozzle 7c, the injection pipe 6c, and the header 5c corresponding to the plate width “small”, as shown by the solid line, and the water adhering to the edge portion of the strip. Blow away and remove. When the plate width changes, the compressed air is supplied to the nozzle, the injection pipe, and the header corresponding thereto.

今、ノズル７をストリップから離す場合、まずエアーの供給を止めてから、操作ハンドル１１のボルト１２を緩めて外し、ハンドルを両手で持って少し左に回し、ハンドルと第２支柱９の両孔にボルトを通して締結する（図３）。これにより、ノズルを含む空気系と共に主フレーム１が少し左に回り、図２の点線示のように、ノズルがストリップから離れた状態となる。   Now, when the nozzle 7 is separated from the strip, first stop the air supply, then loosen and remove the bolt 12 of the operation handle 11, hold the handle with both hands and turn it slightly to the left, both holes of the handle and the second support column 9 And fasten with bolts (FIG. 3). As a result, the main frame 1 rotates slightly to the left together with the air system including the nozzles, and the nozzles are separated from the strip as indicated by the dotted lines in FIG.

図４は他の実施例を示す。操作ハンドル１１を回動、固定させる手段として、第２支柱９に円弧状のスリット９ａを設け、ハンドルの孔とスリットを合わせ、ボルト１２を通し、蝶ナット１３で締結するようにした。これにより、ボルトをいちいち外すことなく、蝶ナットを緩めるだけで、ハンドルの回動範囲を変更可能となる。   FIG. 4 shows another embodiment. As a means for rotating and fixing the operation handle 11, an arc-shaped slit 9a is provided in the second support column 9, the hole of the handle is aligned with the slit, the bolt 12 is passed, and the wing nut 13 is fastened. Thereby, it becomes possible to change the rotation range of the handle only by loosening the wing nut without removing the bolts one by one.

本発明は前記した実施例や実施態様に限定されず、特許請求の範囲および範囲を逸脱せずに種々の変形を含む。   The present invention is not limited to the examples and embodiments described above, and includes various modifications without departing from the scope and scope of the claims.
