Description

本発明は圧延装置、圧延装置のギャップ調整方法に関する。   The present invention relates to a rolling apparatus and a gap adjusting method for the rolling apparatus.

近年、上下に配置された２つの圧延ローラによって電極部材を圧延することで電極を製造する圧延装置が用いられている。この圧延装置では、圧延後の電極の厚みを制御する必要が有る。   2. Description of the Related Art In recent years, rolling apparatuses that produce electrodes by rolling electrode members with two rolling rollers arranged above and below are used. In this rolling apparatus, it is necessary to control the thickness of the electrode after rolling.

長尺の二次電池用電極部材を、２つの圧延ローラにより所望の厚みに精度良く圧延する圧延装置が提案されている（特許文献１）。この圧延装置では、軸受け機構が第２の加圧ローラを第１の加圧ローラに対して接離可能に回転軸支する。荷重機構が第２の加圧ローラを第１の加圧ローラに近接させる方向に押圧する。２つの電極部材の厚み測定装置が、第１および第２の加圧ローラのそれぞれの出側に配設される。制御装置は、厚み測定装置からの出力信号に応じて荷重機構の荷重を制御する。   There has been proposed a rolling device that rolls a long secondary battery electrode member to a desired thickness with two rolling rollers with high accuracy (Patent Document 1). In this rolling apparatus, the bearing mechanism rotatably supports the second pressure roller so as to be able to contact and separate from the first pressure roller. The load mechanism presses the second pressure roller in the direction in which the second pressure roller is brought close to the first pressure roller. Two electrode member thickness measuring devices are disposed on the exit sides of the first and second pressure rollers, respectively. The control device controls the load of the load mechanism according to the output signal from the thickness measuring device.

また、一対のローラの周面間のギャップ長の微調整が容易であり、簡易な構成かつ小型のローラプレス装置が提案されている（特許文献２）。このローラプレス装置では、第１および第２支持部材が、第１および第２ローラのそれぞれを支持する。ガイド部材は、第１および第２支持部材の一方の、他方に対する第１方向の移動を許容し、第２方向の移動を規制する。ここで、第１方向は第１および第２ローラによる圧縮方向以外の方向であり、第２方向は第１方向に直交する方向である。ギャップ調整装置は、第１および第２支持部材の一方を移動させることにより、第１および第２ローラの周面間のギャップ長を調整する。本構成では、ギャップ調整の方向とプレス荷重の方向とが異なる方向となる。よって、重量が重い第１および第２ローラの周面間のギャップ長の微調整が容易となる。その結果、被圧縮物を高精度な厚さにプレスすることができる。この装置では、油圧シリンダを用いないので、装置を小型することができる。   Further, a small roller press apparatus having a simple configuration and a small size is proposed that facilitates fine adjustment of the gap length between the peripheral surfaces of a pair of rollers (Patent Document 2). In this roller press apparatus, the first and second support members support the first and second rollers, respectively. The guide member allows movement in the first direction relative to the other of one of the first and second support members and restricts movement in the second direction. Here, the first direction is a direction other than the compression direction by the first and second rollers, and the second direction is a direction orthogonal to the first direction. The gap adjusting device adjusts the gap length between the peripheral surfaces of the first and second rollers by moving one of the first and second support members. In this configuration, the direction of gap adjustment is different from the direction of press load. Therefore, fine adjustment of the gap length between the peripheral surfaces of the heavy first and second rollers is facilitated. As a result, the object to be compressed can be pressed to a highly accurate thickness. Since this apparatus does not use a hydraulic cylinder, the apparatus can be miniaturized.

更に、２つのローラにより、熱硬化性樹脂が含浸した多孔質炭素系成形品前駆体シート状物を熱硬化する多孔質炭素系成形品前駆体シート状物の熱硬化装置が提案されている（特許文献３）。この熱硬化装置では、回転ローラが、多孔質炭素系成形品前駆体シート状物を連続的に加熱しつつ押圧する。圧力調節手段が、多孔質炭素系成形品前駆体シート状物の厚みを連続的に制御するために、押圧の圧力を連続的に調節する。   Furthermore, a porous carbon-based molded product precursor sheet-like thermosetting apparatus has been proposed in which two rollers are used to thermally cure a porous carbon-based molded product precursor sheet-impregnated with a thermosetting resin ( Patent Document 3). In this thermosetting device, the rotating roller presses the porous carbon-based molded product precursor sheet-like material while heating it continuously. The pressure adjusting means continuously adjusts the pressure of pressing in order to continuously control the thickness of the porous carbon-based molded product precursor sheet.

ところが、発明者は、上述の手法には以下に示す問題点が有ることを見出した。特許文献１では、荷重を変化させて膜厚を調整した場合、ローラや他の部位の温度上昇が上昇する。これにより、膜厚が変化するため、膜厚制御の精度が悪化してしまう。特許文献２では、ローラを異なる方向へ変位させ、押圧する力を保持する機構が必要である。そのため、支持機構が複雑となってしまう。特許文献３は、油圧シリンダのような大型の圧力調整機構が必要であるため、装置が大型化してしまう。   However, the inventor has found that the above-described method has the following problems. In Patent Document 1, when the film thickness is adjusted by changing the load, the temperature rise of the rollers and other parts increases. Thereby, since the film thickness changes, the accuracy of film thickness control deteriorates. In Patent Document 2, a mechanism for holding the pressing force by displacing the roller in different directions is required. This complicates the support mechanism. Since Patent Document 3 requires a large pressure adjustment mechanism such as a hydraulic cylinder, the apparatus becomes large.

一般に、圧延装置では、圧延加工を長時間連続して行うと、２つのローラの表面温度が摩擦により上昇する。この場合、２つのローラの表面が熱膨張し、直径が増大する。そのため、同じ荷重を与え続けていたとしても、圧延加工後の電極部材の厚みが薄くなってしまう。また、圧延加工で電極部材に与える荷重が小さい場合、上記のローラの温度上昇は小さくなる。その結果、２つのローラの温度上昇による厚み変動よりも、他の部位（例えば、ローラ軸支機構やその他のベアリング等）の温度上昇による厚み変動が支配的となる。よって、例えばローラ軸支機構が熱膨張することで２つのローラの表面間の距離（ギャップ）が大きくなり、荷重にかかわらず厚みが増大することとなる。この際、荷重を増加させることで厚みを減少させることができるものの、摩擦の増大などにより圧延装置の温度バラツキが変動し、厚みが不安定化してしまう。   Generally, in a rolling apparatus, when rolling is performed continuously for a long time, the surface temperatures of two rollers rise due to friction. In this case, the surfaces of the two rollers are thermally expanded and the diameter increases. Therefore, even if the same load is continuously applied, the thickness of the electrode member after the rolling process becomes thin. Moreover, when the load given to an electrode member by rolling is small, the temperature rise of said roller becomes small. As a result, the thickness fluctuation due to the temperature rise of other parts (for example, the roller support mechanism and other bearings) becomes more dominant than the thickness fluctuation due to the temperature rise of the two rollers. Therefore, for example, when the roller support mechanism is thermally expanded, the distance (gap) between the surfaces of the two rollers is increased, and the thickness is increased regardless of the load. At this time, although the thickness can be reduced by increasing the load, the temperature variation of the rolling device fluctuates due to an increase in friction and the thickness becomes unstable.

また、荷重が変動した場合でも厚みは変動するものの、荷重と厚みは比例するものではない。更に、上記の通り、厚みは温度変動の影響も受けるため、荷重を調整しても厚みを精度よく制御することは難しい。また、荷重変動に比例するのは電極部材の密度であり、荷重制御を行うと電極部材の目付け量（単位面積あたりの重量）のばらつきがそのまま厚みのばらつきとなる。しかし、電極部材の目付け量を荷重のみで制御するのは、困難である。   Further, even when the load varies, the thickness varies, but the load and the thickness are not proportional. Furthermore, as described above, since the thickness is also affected by temperature fluctuations, it is difficult to accurately control the thickness even if the load is adjusted. In addition, it is the density of the electrode member that is proportional to the load fluctuation, and if load control is performed, the variation in the basis weight (weight per unit area) of the electrode member becomes the variation in thickness as it is. However, it is difficult to control the basis weight of the electrode member only by the load.

実施の形態１
実施の形態１にかかる圧延装置１００について説明する。図１は、実施の形態１にかかる圧延装置１００の構成を示す正面図である。圧延装置１００は、第１ローラ１、第２ローラ２、第１ローラ軸支機構３、第２ローラ軸支機構４及びギャップ調整器５を有する。圧延装置１００は、被圧延部材である電極部材１０を圧延加工する装置である。 Embodiment 1
A rolling device 100 according to the first embodiment will be described. FIG. 1 is a front view showing a configuration of a rolling device 100 according to the first embodiment. The rolling device 100 includes a first roller 1, a second roller 2, a first roller shaft support mechanism 3, a second roller shaft support mechanism 4, and a gap adjuster 5. The rolling device 100 is a device for rolling the electrode member 10 that is a member to be rolled.

第１ローラ１及び第２ローラ２は、回転軸の方向が同じ方向となるように配置される。図１では、第１ローラ１の回転軸１Ａおよび第２ローラ２の回転軸２Ａの軸方向をＹ方向とする。Ｙ方向とは、図１の紙面の手前から奥に向かう方向である。また、図１では、第１ローラ１と第２ローラ２とは、第１ローラ１がＺ方向の＋側、第２ローラ２がＺ方向の−側となるように、Ｚ方向に離隔して配置される。Ｚ方向とは、図１の紙面の下方から上方に向かう方向である。また、図１の紙面右から左へ向かう方向をＸ方向とする。   The 1st roller 1 and the 2nd roller 2 are arrange | positioned so that the direction of a rotating shaft may turn into the same direction. In FIG. 1, the axial direction of the rotation shaft 1A of the first roller 1 and the rotation shaft 2A of the second roller 2 is defined as the Y direction. The Y direction is a direction from the front side to the back side in FIG. In FIG. 1, the first roller 1 and the second roller 2 are separated in the Z direction so that the first roller 1 is on the + side in the Z direction and the second roller 2 is on the − side in the Z direction. Be placed. The Z direction is a direction from the lower side to the upper side in FIG. A direction from the right to the left in FIG.

第１ローラ軸支機構３と第２ローラ軸支機構４とは、荷重が負荷される方向、すなわちＺ方向に離隔して配置される。第１ローラ１は、第１ローラ軸支機構３によって回転可能に軸支される。第２ローラ２は、第２ローラ軸支機構４によって回転可能に軸支される。第１ローラ１及び第２ローラ２は、互いに反対方向に回転することで、狭持する電極部材１０を連続的に搬送する。図１では、第１ローラ１は反時計回りに回転し、第２ローラ２は時計回りに回転する。したがって、電極部材１０は、図１のＸ方向に連続的に搬送される。   The first roller shaft support mechanism 3 and the second roller shaft support mechanism 4 are arranged separately in the direction in which the load is applied, that is, in the Z direction. The first roller 1 is rotatably supported by a first roller shaft support mechanism 3. The second roller 2 is rotatably supported by a second roller shaft support mechanism 4. The 1st roller 1 and the 2nd roller 2 convey the electrode member 10 pinched continuously by rotating in the mutually opposite direction. In FIG. 1, the first roller 1 rotates counterclockwise, and the second roller 2 rotates clockwise. Therefore, the electrode member 10 is continuously conveyed in the X direction of FIG.

図２は、ギャップ調整器５の拡大図である。以下、ギャップとは、第１ローラ軸支機構３のＺ方向−側の面と、第２ローラ軸支機構４のＺ方向＋側の上面と、の間の距離を指すものとする。ギャップ調整器５は、回転軸５Ａから外周までの距離が一様ではない回転部材である。ギャップ調整器５を構成する回転部材は、少なくとも、回転させた場合に第１ローラ軸支機構３と第２ローラ軸支機構４のそれぞれに接する外周面の前記回転軸からの距離が連続的に変化する部材として構成される。すなわち、ギャップ調整器５は、第１ローラ軸支機構３と第２ローラ軸支機構４のそれぞれに接する部位が、互いに長さが異なる長径ｂと短径ａとを有する回転部材である。   FIG. 2 is an enlarged view of the gap adjuster 5. Hereinafter, the gap refers to the distance between the surface on the Z direction − side of the first roller shaft support mechanism 3 and the upper surface on the Z direction + side of the second roller shaft support mechanism 4. The gap adjuster 5 is a rotating member whose distance from the rotating shaft 5A to the outer periphery is not uniform. When the rotating member constituting the gap adjuster 5 is rotated, at least the distance from the rotating shaft of the outer peripheral surface in contact with each of the first roller supporting mechanism 3 and the second roller supporting mechanism 4 is continuous. It is configured as a changing member. In other words, the gap adjuster 5 is a rotating member that has a major axis “b” and a minor axis “a” that are in contact with each of the first roller pivot mechanism 3 and the second roller pivot mechanism 4.

また、ギャップ調整器５を構成する回転部材は、回転させた場合に第１ローラ軸支機構３に接する外周面と回転させた場合に第２ローラ軸支機構４に接する外周面とが、回転軸５Ａに対して対称な形状（点対称）であることが望ましい。この場合、ギャップ調整器５を構成する回転部材を回転させた際の、回転軸５Ａに対する第１ローラ軸支機構３のＺ方向変位量と、回転軸５Ａに対する第２ローラ軸支機構４のＺ方向変位量とを等しくできる。その結果、ギャップの調整を精密に行うことが可能となる。   Further, the rotating member constituting the gap adjuster 5 rotates between the outer peripheral surface in contact with the first roller support mechanism 3 when rotated and the outer peripheral surface in contact with the second roller support mechanism 4 when rotated. It is desirable that the shape be symmetrical with respect to the axis 5A (point symmetry). In this case, when the rotating member constituting the gap adjuster 5 is rotated, the Z-direction displacement amount of the first roller support mechanism 3 with respect to the rotation shaft 5A and the Z of the second roller support mechanism 4 with respect to the rotation shaft 5A. The direction displacement can be made equal. As a result, the gap can be adjusted precisely.

図１では、一例として、ギャップ調整器５を楕円形の回転部材としている。また、ギャップ調整器５の回転軸５Ａは、第１ローラ１の回転軸１Ａおよび第２ローラ２の回転軸２Ａと平行（Ｙ方向）である。ギャップ調整器５の回転方向は時計回りでも反時計回りでもよい。   In FIG. 1, as an example, the gap adjuster 5 is an elliptical rotating member. The rotating shaft 5A of the gap adjuster 5 is parallel to the rotating shaft 1A of the first roller 1 and the rotating shaft 2A of the second roller 2 (Y direction). The rotation direction of the gap adjuster 5 may be clockwise or counterclockwise.

ギャップ調整器５は、圧延方向（すなわち、Ｚ方向）に対向する第１ローラ軸支機構３のＺ方向−側の面と第２ローラ軸支機構４のＺ方向＋側の上面との間に挟み込まれるように配置される。上記したように、ギャップ調整器５は回転軸５Ａから外周までの距離が一様ではない回転部材であるので、ギャップ調整器５の回転角に応じて、第１ローラ軸支機構３のＺ方向−側の面と第２ローラ軸支機構４のＺ方向＋側の上面との間の距離が変化する。すなわち、ギャップ調整器５の回転角に応じて、第１ローラ軸支機構３に軸支される第１ローラ１と第２ローラ軸支機構４に軸支される第２ローラ２との間の距離（ギャップとも称する）が変化する。例えば、ギャップ調整器５の回転角を、ギャップ調整器５の短径ａがＺ方向に沿うような角度とすることで、第１ローラ１と第２ローラ２との間のギャップを最短にすることができる。ギャップ調整器５の回転角を、ギャップ調整器５の長径ｂがＺ方向に沿うような角度とすることで、第１ローラ１と第２ローラ２との間のギャップを最長にすることができる。また、図１に示すように、ギャップ調整器５が楕円形であれば、ギャップ調整器５の回転角により、第１ローラ１と第２ローラ２との間のギャップを最短から最長の間で連続的に変化させることができる。   The gap adjuster 5 is provided between the Z-direction-side surface of the first roller shaft support mechanism 3 and the upper surface of the second roller shaft support mechanism 4 on the Z direction + side, which are opposed to each other in the rolling direction (that is, the Z direction). Arranged to be sandwiched. As described above, since the gap adjuster 5 is a rotating member whose distance from the rotating shaft 5A to the outer periphery is not uniform, the Z direction of the first roller support mechanism 3 depends on the rotation angle of the gap adjuster 5. The distance between the − side surface and the upper surface of the second roller shaft support mechanism 4 in the Z direction + side changes. That is, according to the rotation angle of the gap adjuster 5, between the first roller 1 supported by the first roller support mechanism 3 and the second roller 2 supported by the second roller support mechanism 4. The distance (also referred to as a gap) changes. For example, the gap angle between the first roller 1 and the second roller 2 is minimized by setting the rotation angle of the gap adjuster 5 so that the minor axis a of the gap adjuster 5 is along the Z direction. be able to. The gap between the first roller 1 and the second roller 2 can be maximized by setting the rotation angle of the gap adjuster 5 so that the major axis b of the gap adjuster 5 is along the Z direction. . In addition, as shown in FIG. 1, if the gap adjuster 5 is elliptical, the gap between the first roller 1 and the second roller 2 is changed from the shortest to the longest by the rotation angle of the gap adjuster 5. Can be changed continuously.

なお、ギャップ調整器５は楕円形の回転部材であるものと説明したが、これは例示に過ぎない。例えば、ギャップ調整器５は、回転軸に対して点対称な断面でなくともよく、卵型などの他の形状でもよい。また、径が連続的に変化する形状であれば、楕円径及び卵型以外の形状としてもよい。   Although the gap adjuster 5 has been described as an elliptical rotating member, this is merely an example. For example, the gap adjuster 5 may not have a point-symmetric cross section with respect to the rotation axis, and may have another shape such as an egg shape. Moreover, as long as the diameter changes continuously, the shape may be other than the elliptical diameter and the egg shape.

以上、本構成によれば、ギャップ調整器５の回転角を調整することで、荷重制御とは独立して、ギャップを調整することができる。かつ、ギャップ調整器５は、単に２つのローラ軸支機構間に挟まれた回転部材であるので、構成が簡易であり、小さなコストで導入することが可能である。   As described above, according to this configuration, the gap can be adjusted independently of the load control by adjusting the rotation angle of the gap adjuster 5. Moreover, since the gap adjuster 5 is simply a rotating member sandwiched between two roller shaft support mechanisms, the structure is simple and can be introduced at a low cost.

実施の形態２
実施の形態２にかかる圧延装置２００について説明する。図３は、実施の形態２にかかる圧延装置２００の構成を示す正面図である。圧延装置２００は、圧延装置１００にギャップ調整器駆動機構６、厚み測定機７及び制御装置８を追加した構成を有する。 Embodiment 2
A rolling device 200 according to the second embodiment will be described. FIG. 3 is a front view showing the configuration of the rolling apparatus 200 according to the second embodiment. The rolling device 200 has a configuration in which a gap adjuster driving mechanism 6, a thickness measuring device 7, and a control device 8 are added to the rolling device 100.

ギャップ調整器駆動機構６は、ギャップ調整器５を回転駆動可能に軸支している。ギャップ調整器駆動機構６は、ギャップ調整器５が所定の回転角となるように駆動することで、第１ローラ１と第２ローラ２との間のギャップを調整する。ギャップ調整器駆動機構６は、単に駆動機構とも称する。   The gap adjuster drive mechanism 6 pivotally supports the gap adjuster 5 so as to be rotationally driven. The gap adjuster driving mechanism 6 adjusts the gap between the first roller 1 and the second roller 2 by driving the gap adjuster 5 to have a predetermined rotation angle. The gap adjuster drive mechanism 6 is also simply referred to as a drive mechanism.

厚み測定機７は、圧延加工後の電極部材１０の厚みを連続的に測定し、測定結果を制御装置８に出力する。制御装置８は、厚み測定機７の測定結果を監視し、圧延加工後の電極部材の厚みが所定の範囲内に収まるようにフィードバック制御を行う。具体的には、ギャップ調整器駆動機構６は、制御装置８からの制御に応じて、所望の回転角までギャップ調整器５を回転駆動する。   The thickness measuring device 7 continuously measures the thickness of the electrode member 10 after the rolling process, and outputs the measurement result to the control device 8.

ステップＳ１
制御装置８が、厚み測定機７での厚み測定値Ｔｍｅａｓが厚み規格下限値Ｔｍｉｎ以上であるか（Ｔｍｅａｓ≧Ｔｍｉｎ）を判定する。 Step S1
The control device 8 determines whether the thickness measurement value Tmeas in the thickness measuring device 7 is equal to or greater than the thickness standard lower limit value Tmin (Tmeas ≧ Tmin).

ステップＳ２
ステップＳ１における厚み測定機７での厚み測定値Ｔｍｅａｓが厚み規格下限値Ｔｍｉｎよりも小さい場合、制御装置８はギャップ調整器駆動機構６を制御して、第１ローラ１と第２ローラ２との間のギャップを増加させる。その後、ステップＳ１に戻り、厚み調整動作を継続する。 Step S2
When the thickness measurement value Tmeas in the thickness measuring machine 7 in step S1 is smaller than the thickness standard lower limit value Tmin, the control device 8 controls the gap adjuster driving mechanism 6 to determine the first roller 1 and the second roller 2. Increase the gap between. Then, it returns to step S1 and continues thickness adjustment operation.

ステップＳ３
ステップＳ１における厚み測定機７での厚み測定値Ｔｍｅａｓが厚み規格下限値Ｔｍｉｎ以上である場合、制御装置８は、厚み測定機７での厚み測定値Ｔｍｅａｓが厚み規格上限値Ｔｍａｘ以下であるか（Ｔｍｅａｓ≦Ｔｍａｘ）を判定する。厚み測定値Ｔｍｅａｓが厚み規格上限値Ｔｍａｘ以下である場合、ステップＳ１に戻り、厚み調整動作を継続する。 Step S3
When the thickness measurement value Tmeas in the thickness measuring device 7 in step S1 is equal to or greater than the thickness specification lower limit value Tmin, the control device 8 determines whether the thickness measurement value Tmeas in the thickness measurement device 7 is equal to or less than the thickness specification upper limit value Tmax ( Tmeas ≦ Tmax) is determined. When the thickness measurement value Tmeas is equal to or less than the thickness standard upper limit value Tmax, the process returns to step S1 and the thickness adjustment operation is continued.

ステップＳ４
ステップＳ３における厚み測定機７での厚み測定値Ｔｍｅａｓが厚み規格上限値Ｔｍａｘよりも大きい場合、制御装置８はギャップ調整器駆動機構６を制御して、第１ローラ１と第２ローラ２との間のギャップを減少させる。その後、ステップＳ１に戻り、厚み調整動作を継続する Step S4

以下、圧延加工の実施例を示す。厚さ１５μｍのアルミ箔の心材両面に活物質を塗工し、被圧延部材である厚さ１６０μｍの電極部材を搬送速度８０ｍ／ｍｉｎ、ロールギャップ補正を１μｍに設定して、圧延装置２００による圧延加工を行った。   Examples of rolling are shown below. Rolling by rolling apparatus 200 by applying active material on both sides of core material of aluminum foil with thickness of 15 μm, setting electrode member with thickness of 160 μm to be rolled as conveyance speed of 80 m / min and roll gap correction of 1 μm Processing was performed.

ケース１
初期圧延荷重２０ｔにて３０００ｍの連続圧延を行ったところ、電極部材の厚みの減少量を１μｍに抑制できた。これに対し、ギャップ調整器５を有しない圧延装置で同様の圧延加工を実施したところ、電極部材の厚みの減少量は３μｍであった。これにより、ギャップ調整器５を用いた厚み調整動作により、電極部材の厚み減少を抑制できることが理解できる。 Case 1
When continuous rolling of 3000 m was performed with an initial rolling load of 20 t, the decrease in thickness of the electrode member could be suppressed to 1 μm. On the other hand, when the same rolling process was carried out with a rolling machine that does not have the gap adjuster 5, the amount of decrease in the thickness of the electrode member was 3 μm. Thereby, it can be understood that the thickness adjustment operation using the gap adjuster 5 can suppress the decrease in the thickness of the electrode member.

ケース２
初期圧延荷重２ｔにて５００ｍの連続圧延を行ったところ、電極部材の厚みの増加量を１μｍに抑制できた。これに対し、ギャップ調整器５を有しない圧延装置で同様の圧延加工を実施したところ、電極部材の厚みの増加量は２μｍであった。これにより、ギャップ調整器５を用いた厚み調整動作により、電極部材の厚み増加を抑制できることが理解できる。 Case 2
When continuous rolling of 500 m was performed with an initial rolling load of 2 t, the increase in thickness of the electrode member could be suppressed to 1 μm. On the other hand, when the same rolling process was carried out with a rolling apparatus that does not have the gap adjuster 5, the increase in the thickness of the electrode member was 2 μm. Thereby, it can be understood that an increase in the thickness of the electrode member can be suppressed by the thickness adjusting operation using the gap adjuster 5.

以上より、本構成によれば、圧延加工の条件によらず、ギャップ調整器５を用いた厚み調整動作により、電極部材の厚み変動を抑制できることが理解できる。換言すれば、本構成によれば、圧延装置の荷重や温度の変動による圧延加工後の電極部材１０の厚みの変化を検出して、電極部材１０の厚みを所望の範囲に収めることができる。   From the above, according to this configuration, it can be understood that the thickness variation of the electrode member can be suppressed by the thickness adjusting operation using the gap adjuster 5 regardless of the rolling process conditions. In other words, according to the present configuration, it is possible to detect a change in the thickness of the electrode member 10 after the rolling process due to a load of the rolling device or a change in temperature, and to keep the thickness of the electrode member 10 in a desired range.

また、圧延装置２００は、第１ローラ１と第２ローラ２との間に圧延荷重を生じさせる荷重センサ２１及び荷重発生装置２２を更に有してもよい。図５は、実施の形態２にかかる圧延装置２００に荷重センサ２１及び荷重発生装置２２を付加した圧延装置２０１の構成を示す正面図である。なお、図面の簡略化のため、図５では軸受け３Ａ及びハウジング３Ｂを分けずに単に第１ローラ軸支機構３として表示し、軸受け４Ａ及びハウジング４Ｂを分けずに単に第２ローラ軸支機構４として表示している。   The rolling device 200 may further include a load sensor 21 and a load generator 22 that generate a rolling load between the first roller 1 and the second roller 2. FIG. 5 is a front view showing a configuration of a rolling apparatus 201 in which a load sensor 21 and a load generating apparatus 22 are added to the rolling apparatus 200 according to the second embodiment. For simplification of the drawing, in FIG. 5, the bearing 3A and the housing 3B are not shown separately, but are simply indicated as the first roller support mechanism 3, and the bearing 4A and the housing 4B are not shown separately and the second roller support mechanism 4 is simply shown. It is displayed as.

荷重センサ２１は、第１ローラ１と第２ローラ２とに付加された圧延荷重を検出する。荷重発生装置２２は、第１ローラ１及び第２ローラ２の一方又は両方に圧延方向かつ第１ローラ１と第２ローラ２とが近づく方向の力を与える。これにより、第１ローラ１と第２ローラ２との間の電極部材１０に圧延荷重が与えられる。このとき、制御装置８は、荷重センサ２１の測定結果に応じて荷重発生装置２２を制御し、電極部材１０に与える荷重を調整することができる。   The load sensor 21 detects a rolling load applied to the first roller 1 and the second roller 2. The load generator 22 applies a force in the rolling direction and the direction in which the first roller 1 and the second roller 2 approach to one or both of the first roller 1 and the second roller 2. Thereby, a rolling load is applied to the electrode member 10 between the first roller 1 and the second roller 2. At this time, the control device 8 can adjust the load applied to the electrode member 10 by controlling the load generator 22 according to the measurement result of the load sensor 21.

その他の実施の形態
なお、本発明は上記実施の形態に限られたものではなく、趣旨を逸脱しない範囲で適宜変更することが可能である。例えば、図４におけるステップＳ１とステップＳ３とは、順序を入れかえても同様の厚み調整動作を実現できることは言うまでもない。 Other Embodiments The present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention. For example, it goes without saying that the same thickness adjustment operation can be realized even if the order of steps S1 and S3 in FIG. 4 is changed.

被圧延部材として電極部材について説明したが、これは例示に過ぎない。すなわち、電極部材以外の任意の被圧延部材を圧延してもよいことは、いうまでもない。   Although the electrode member has been described as the member to be rolled, this is merely an example. That is, it goes without saying that any rolled member other than the electrode member may be rolled.

上述の図３における第１ローラ軸支機構３及び第２ローラ軸支機構４の構成は、実施の形態１にかかる圧延装置１００に適用してもよいことはいうまでもない。   Needless to say, the configurations of the first roller support mechanism 3 and the second roller support mechanism 4 in FIG. 3 described above may be applied to the rolling apparatus 100 according to the first embodiment.
