Description

本発明は、長尺状のウエブが走行中に蛇行した場合に、その蛇行を修正するウエブの蛇行修正装置に関するものである。   The present invention relates to a meandering correction device for a web that corrects meandering when a long web meanders during traveling.

合成樹脂フィルム、紙、布、金属箔等の長尺状のウエブは、その乾燥、塗工等の加工を施すときに、高速で走行しているため搬送路から変位する横ずれ、いわゆる蛇行が生じ易い。   Long webs such as synthetic resin film, paper, cloth, metal foil, etc., when they are dried, coated, etc., run at a high speed, causing lateral displacement that shifts from the conveyance path, so-called meander easy.

このようなウエブの蛇行を修正する装置として、図１０及び図１１に示すように、ウエブＷが走行する修正ロール１００を軸方向に移動させて蛇行量を修正している（例えば、特許文献１参照）。
特開２００２−２８４４１５公報 As a device for correcting the meandering of the web, as shown in FIGS. 10 and 11, the meandering amount is corrected by moving the correction roll 100 on which the web W travels in the axial direction (for example, Patent Document 1). reference).
JP 2002-284415 A

上記のような修正ロールを用いるウエブの蛇行修正装置において、修正ロール１００によって蛇行を修正しているときに、ウエブＷの歪みが大きくなり、蛇行が正常になっても、ウエブＷに皺が発生することがあった。   In the meandering correction device for a web using the correcting roll as described above, when the meandering is corrected by the correcting roll 100, the distortion of the web W becomes large, and even if the meandering becomes normal, wrinkles occur in the web W. There was something to do.

そこで、本発明は上記問題点に鑑み、ウエブの蛇行量を修正しているときに、ウエブの歪みが少なくなり、皺が形成されないウエブの蛇行修正装置を提供する。   Accordingly, in view of the above problems, the present invention provides a web meander correcting device in which web distortion is reduced and wrinkles are not formed when the meandering amount of the web is corrected.

本発明は、修正ロールによって、走行するウエブの蛇行状態を修正するウエブの蛇行修正装置において、前記修正ロールの中央部の表面について、前記ウエブの滑り止め加工し、前記中央部以外の両側部の表面の摩擦係数が閾値より小さくなるように加工した、ウエブの蛇行修正装置である。   The present invention provides a meandering correction device for a web that corrects a meandering state of a traveling web with a correction roll, and the anti-slip processing of the web is performed on the surface of the central portion of the correction roll, and the both sides other than the central portion are processed. This is a meandering correction device for a web which is processed so that the friction coefficient of the surface is smaller than a threshold value.

本発明によれば、ウエブの蛇行を修正するために、修正ロールを幅方向におおよそ円弧状に移動させるが、この移動によりウエブの左右の張力が変動する。しかし、本実施形態の修正ロールの場合、ウエブの両側部の張力変動を小さくし、皺や歪みの形成を防止することができる。一方、修正ロールの中央部の摩擦力が大きくなるため、ウエブを修正ロールの移動方向へ強く導くことができる。   According to the present invention, in order to correct the meandering of the web, the correction roll is moved approximately in an arc shape in the width direction, and the left and right tensions of the web fluctuate due to this movement. However, in the case of the correction roll of the present embodiment, it is possible to reduce the fluctuation in tension on both sides of the web and prevent the formation of wrinkles and distortions. On the other hand, since the frictional force at the center of the correction roll is increased, the web can be strongly guided in the moving direction of the correction roll.

以下、本発明の一実施形態のウエブＷの蛇行修正装置１０について図１〜図５に基づいて説明する。   Hereinafter, a meandering correction device 10 for a web W according to an embodiment of the present invention will be described with reference to FIGS.

本実施形態のウエブＷの蛇行修正装置１０は、図１に示すようなウエブＷの乾燥工程において使用されるものであり、ウエブＷとしては、例えば、合成樹脂フィルム、金属箔、布、紙等である。   The meandering correction device 10 of the web W according to the present embodiment is used in a drying process of the web W as shown in FIG. 1, and examples of the web W include a synthetic resin film, metal foil, cloth, paper, and the like. It is.

（１）乾燥工程の構成
図１に基づいて、ウエブＷの乾燥工程を行うシステムについて説明する。 (1) Structure of drying process The system which performs the drying process of the web W is demonstrated based on FIG.

ウエブＷは、巻き出し装置１２から搬出され、案内ロール１４，１６を経て乾燥装置１８に搬入される。乾燥装置１８で乾燥されたウエブＷは、蛇行を修正するための修正ロール２０を経て、案内ロール２２を通り巻き取り装置２４に巻き取られる。   The web W is unloaded from the unwinding device 12 and is loaded into the drying device 18 through the guide rolls 14 and 16. The web W dried by the drying device 18 passes through a guide roll 22 through a correction roll 20 for correcting meandering, and is taken up by a winding device 24.

この乾燥装置１８は、ウエブＷの走行路の下方と上方にそれぞれ上ノズル１８２と下ノズル１８４が千鳥状に配列され、上下ノズル１８２，１８４から熱風を吹き出すことによりウエブＷを熱処理することができる。この場合に、ウエブＷは上下ノズル１８２，１８４との間で浮上した形で走行する。   In this drying device 18, an upper nozzle 182 and a lower nozzle 184 are arranged in a staggered manner below and above the traveling path of the web W, and the web W can be heat-treated by blowing hot air from the upper and lower nozzles 182 and 184. . In this case, the web W travels in the form of floating between the upper and lower nozzles 182 and 184.

本実施形態の蛇行修正装置１０は、修正ロール２０によってウエブＷの蛇行量を調整するための装置である。   The meandering correction device 10 of this embodiment is a device for adjusting the meandering amount of the web W by the correction roll 20.

（２）蛇行修正装置１０の構成
次に、蛇行修正装置１０について図２〜図４に基づいて説明する。 (2) Configuration of Meandering Correction Device 10 Next, the meandering correction device 10 will be described with reference to FIGS.

蛇行修正装置１０は、ステアリングローラ方式で修正ロール２０を軸方向に移動させる。   The meandering correction device 10 moves the correction roll 20 in the axial direction by a steering roller method.

具体的には、固定台２６の上に、移動台２８が配され、この移動台２８の上面に修正ロール２０が回動自在に支持されている。即ち、修正ロール２０は、移動台２８から突出した一対の支持部３０，３０によって回動自在に保持されている。   Specifically, a moving table 28 is disposed on the fixed table 26, and the correction roll 20 is rotatably supported on the upper surface of the moving table 28. That is, the correction roll 20 is rotatably held by a pair of support portions 30 and 30 protruding from the movable table 28.

固定台２６の上面には、左右一対の円弧状のレール３２，３４が２組設けられている。移動台２８の下面には４個の車輪３６が設けられ、前記左右一対のレール３２，３４に移動自在に載置されている。これによって、固定台２６に対し、移動台２８は修正ロール２０の軸方向に移動する。但し、完全な軸方向ではなく、自動車のステアリングと同様に左レール３２，右レール３４がそれぞれ１つの中心に向かって円弧状に形成して、走行するウエブＷに対し修正ロール２０が円弧状に移動して、ウエブの蛇行を調整する。なお、修正ロール２０については、後から詳しく説明する。   Two pairs of left and right arc-shaped rails 32 and 34 are provided on the upper surface of the fixed base 26. Four wheels 36 are provided on the lower surface of the moving table 28 and are movably mounted on the pair of left and right rails 32 and 34. Accordingly, the moving table 28 moves in the axial direction of the correction roll 20 with respect to the fixed table 26. However, the left rail 32 and the right rail 34 are each formed in an arc shape toward one center as in the case of the steering of an automobile, and the correction roll 20 is in an arc shape with respect to the traveling web W, not in a complete axial direction. Move to adjust the meandering of the web. The correction roll 20 will be described in detail later.

この移動台２８を軸方向に移動させるために、回動自在にネジ棒３８が側部に取り付けられ、このネジ棒３８が修正モータ４０によって回動する。この修正モータ４０が回転するとネジ棒３８も回転し、移動台２８を軸方向に引っ張るか、または、押すことによって修正ロール２０が軸方向に移動する。   In order to move the moving base 28 in the axial direction, a screw rod 38 is rotatably attached to the side portion, and the screw rod 38 is rotated by a correction motor 40. When the correction motor 40 rotates, the screw rod 38 also rotates, and the correction roll 20 moves in the axial direction by pulling or pushing the moving table 28 in the axial direction.

また、修正ロール２０の近傍であって、ウエブＷの右縁部の位置を検出するためのセンサー４２が設けられている。このセンサー４２の検出位置によって、ウエブＷが蛇行しているか否かを判断する。   A sensor 42 for detecting the position of the right edge of the web W near the correction roll 20 is provided. Whether or not the web W is meandering is determined based on the detection position of the sensor 42.

（３）修正ロール２０
図２、図３に示すように、修正ロール２０は、円柱状のロール本体２０２の両端部から軸２０４がそれぞれ突出している。 (3) Correction roll 20
As shown in FIGS. 2 and 3, the correction roll 20 has shafts 204 protruding from both ends of a cylindrical roll body 202.

このロール本体２０２の中央部２０６には、螺旋状の溝が設けられ、滑り止め加工を行なっている。この中央部２０６の長さＭは、ロール本体２０２の全幅をＬとした場合、ＭはＬに対し２０〜７０％、好適には４０〜６０％である。また、中央部２０６以外の両側部２０８，２０８には、平滑なメッキ加工を施して、この部分の摩擦係数が実験で求めた閾値より小さくなるようにしている。   A spiral groove is provided in the central portion 206 of the roll body 202 to perform anti-slip processing. The length M of the central portion 206 is 20 to 70%, preferably 40 to 60% with respect to L, where L is the total width of the roll body 202. Further, the side portions 208 and 208 other than the central portion 206 are subjected to smooth plating so that the friction coefficient of these portions is smaller than the threshold value obtained through experiments.

この修正ロール２０の材質は、樹脂含浸を行なったカーボンファイバー、ゴム製、または、金属製である。また、この修正ロール２０の直径は、７０〜２００ｍｍ（好適には、１００ｍｍ〜１５０ｍｍである）であり、全幅は２５０ｍｍ〜５ｍ（好適には１．５〜３ｍ）である。   The material of the correction roll 20 is carbon fiber, rubber, or metal that has been impregnated with resin. The diameter of the correction roll 20 is 70 to 200 mm (preferably 100 mm to 150 mm), and the total width is 250 mm to 5 m (preferably 1.5 to 3 m).

（４）効果
本実施形態において、乾燥装置１８の出口付近ではウエブＷには次の４つの力が作用する。 (4) Effects In the present embodiment, the following four forces act on the web W near the outlet of the drying device 18.

第１は、修正ロール２０が幅方向に移動することにより、その摩擦力によりウエブＷを修正ロール２０の移動と同じ量を移動させる。   First, when the correction roll 20 moves in the width direction, the web W is moved by the same amount as the movement of the correction roll 20 by the friction force.

第２は、修正ロール２０が斜めになることにより、その走行方向にウエブＷを移動させる。   Second, when the correction roll 20 is inclined, the web W is moved in the traveling direction.

第３は、修正ロール２０が斜めになることにより、左右でウエブＷの張力が変動するが、ウエブＷには張力が高い方向へ移動する力が働く。   Third, when the correction roll 20 is inclined, the tension of the web W fluctuates on the left and right, but the web W is subjected to a force that moves in a higher tension direction.

第４は、図１に示すように空気浮上型の乾燥装置１８においては、修正ロール２０が移動することにより左右の張力が変化すると張力の弱いほうが乾燥装置１８のノズル１８２，１８４より離れ、ウエブＷとノズルが平行でなくなり、このことにより空気力よりウエブＷには張力の高い方向へ移動する力が働く。   Fourth, as shown in FIG. 1, in the air floating type drying device 18, when the right and left tension changes due to the movement of the correction roll 20, the weaker tension is separated from the nozzles 182 and 184 of the drying device 18, and the web W and the nozzle are no longer parallel, and this causes a force to move in a higher tension direction on the web W than aerodynamic force.

以上により、第１と第２の力はウエブＷの蛇行を修正する方向に働き、第３及び第４の力はウエブＷの蛇行を増す方向に働く。このことにより、蛇行を修正するには第１と第２の力を大きくし、第３と第４の力を小さくする必要がある。そこで、本実施形態のように修正ロール２０の幅方向において、中央部２０２の摩擦力を上げ、両側部２０８，２０６の摩擦力を小さくすることにより、蛇行修正力を高めることができる。   Thus, the first and second forces act in the direction of correcting the meandering of the web W, and the third and fourth forces act in the direction of increasing the meandering of the web W. Thus, in order to correct the meandering, it is necessary to increase the first and second forces and decrease the third and fourth forces. Therefore, the meandering correction force can be increased by increasing the frictional force of the central portion 202 and decreasing the frictional forces of the side portions 208 and 206 in the width direction of the correction roll 20 as in this embodiment.

すなわち、滑り止め加工を行った中央部２０２の摩擦力を大きくすることにより、ウエブＷを修正ロール２０の移動方向へ強く導くことができ、両側部２０８，２０６の摩擦力を小さくすることにより左右の張力変動を小さくすることができる。   That is, the web W can be strongly guided in the moving direction of the correction roll 20 by increasing the frictional force of the center portion 202 subjected to the anti-slip process, and the left and right sides can be reduced by decreasing the frictional force of the side portions 208 and 206. It is possible to reduce the fluctuation in tension.
