圧延材誘導装置Rolled material guidance system
　本発明は、圧延材誘導装置に関し、特に、圧延機に圧延材を誘導する圧延材誘導装置に適用して有効な技術に関するものである。 The present invention relates to a rolled material guidance device, and more particularly to a technique effective when applied to a rolled material guidance device that guides a rolled material to a rolling mill.
　圧延材を圧延して棒鋼や線材を形成する圧延ラインにおいては、圧延材を正確に芯出しして圧延機に送り込む必要がある。そのため、従来から圧延機の圧延材進入側には、圧延材を誘導（案内）する圧延材誘導装置が設けられている。この圧延材誘導装置においては、様々な構造のものが提案され、実用化されている。例えば、特許文献１には、圧延軸線を中心に放射状に配置された複数の案内ローラによって圧延材を圧延機に案内して誘導する圧延材誘導装置が開示されている。各案内ローラは、フレーム本体に旋回軸に旋回可能の軸支されたアングル状のレバーの一方の脚部に回転可能に取り付けられている。そして、各レバーと調節ブッシュとが連結ロッドによって連結され、調節ブッシュを圧延軸線の方向に摺動することによって各レバーがそれぞれの旋回軸を中心に旋回して各案内ローラと圧延軸線との間の距離を同時に調節することが可能になっている。 In a rolling line where rolled materials are rolled to form steel bars and wire rods, it is necessary to accurately center the rolled materials and send them to the rolling mill. Therefore, conventionally, a rolled material guidance device for guiding the rolled material is provided on the rolling material approach side of the rolling mill. In this rolled material guidance system, those having various structures have been proposed and put into practical use. For example, Patent Document 1 discloses a rolled material guidance device that guides a rolled material to a rolling mill by a plurality of guide rollers arranged radially around a rolling axis. Each guide roller is rotatably attached to one leg of an angle-shaped lever that is pivotally supported by a swivel shaft on the frame body. Then, each lever and the adjusting bush are connected by a connecting rod, and by sliding the adjusting bush in the direction of the rolling axis, each lever rotates around the respective turning axis and is between each guide roller and the rolling axis. It is possible to adjust the distance of.

　ところで、特許文献１の圧延材誘導装置では、連結ロッドとレバーとの間に皿ばねからなる弾性部材を設けている。この弾性部材により案内ローラへの負荷軽減を図ることが可能である。また、弾性部材の予張力は保持リングによって変更可能であり、案内ローラへの負荷低減の度合も調整することができる。さらに、調節ブッシュによって案内ローラと圧延軸線との間の開度を調整することも可能である。
　しかしながら、調節ブッシュは装置本体（フレーム）に対して圧延軸線方向に摺動可能な構造としてあり、案内ローラの開度調整は、装置本体に対する調節ブッシュの位置を調整することで行う構成であるため、装置本体に調節機構を設ける必要があり、装置構成が大掛かりとなる。さらに、ひとつの調節ブッシュで、複数の案内ローラの開度調整を行うように構成されており、個々の案内ローラの開度調整を個別に行うことはできない。 By the way, in the rolled material guidance device of Patent Document 1, an elastic member made of a disc spring is provided between the connecting rod and the lever. With this elastic member, it is possible to reduce the load on the guide roller. Further, the pretension of the elastic member can be changed by the holding ring, and the degree of load reduction on the guide roller can be adjusted. Further, the opening degree between the guide roller and the rolling axis can be adjusted by the adjusting bush.
However, the adjusting bush has a structure that allows it to slide in the rolling axis direction with respect to the device body (frame), and the opening degree of the guide roller is adjusted by adjusting the position of the adjusting bush with respect to the device body. , It is necessary to provide an adjustment mechanism in the main body of the device, which makes the device configuration large. Further, one adjusting bush is configured to adjust the opening degree of a plurality of guide rollers, and the opening degree of each guide roller cannot be adjusted individually.

The support unit is provided in the above and has a support unit that presses the receiving surface by the rotational force, and the support unit has a connecting member that connects to the other end side of the roller holder and a contact surface that comes into contact with the receiving surface. The connecting member has a cushion portion, a second elastic member existing between the connecting member and the cushion portion, and a holding member of the cushion portion that prevents the cushion portion from coming off from the support unit. The position of the support unit in the rotation direction with respect to the roller holder can be adjusted by being screwed to the roller holder with the rotation direction centered on the rotation support shaft on the other end side of the roller holder as the axis. The cushion portion is slidable with respect to the coupling member in the rotational direction, and the second elastic member acts in a direction in which the elastic force acts substantially coincides with the sliding direction of the cushion portion. An elastic member exists between the connecting member and the cushion portion, and the holding member meshes with the connecting member or the cushion portion to restrict the amount of protrusion of the cushion portion from the connecting member in the sliding direction. It has an engaging portion and an adjusting screw that adjusts the elastic force of the second elastic member in a state where the engaging portion is in mesh with the connecting member.

The rolled material 1 is guided to the rolling mill 2 along the pass line 3. The rolled material guidance device 10 may be installed on the downstream side (rolled material discharge side) of the rolling mill 2 in order to prevent runout of the rolled material 1 after rolling.
　図２及び図３に示すように、本発明の一実施形態に係る圧延材誘導装置１０は、略円筒形状のハウジングからなるフレーム（装置本体）１１と、パスライン３を通過する圧延材１に接触して圧延材１を圧延機２に誘導するガイドローラ（案内ローラ）１２と、一端側と他端側との間の中間部が回転支持軸１３を介してフレーム１１に揺動自在に支持され、かつ一端側にガイドローラ１２が回転自在に取り付けられたローラホルダ１４と、を備えている。また、一実施形態に係る圧延材誘導装置１０は、ローラホルダ１４の他端側をフレーム１１に支持する支持ユニット２０を備えている。 As shown in FIGS. 2 and 3, the rolled material guiding device 10 according to the embodiment of the present invention includes a frame (device body) 11 having a substantially cylindrical housing and a rolled material 1 passing through a pass line 3. A guide roller (guide roller) 12 that contacts and guides the rolled material 1 to the rolling mill 2 and an intermediate portion between one end side and the other end side are swingably supported by the frame 11 via a rotation support shaft 13. It is provided with a roller holder 14 to which a guide roller 12 is rotatably attached to one end side.

　ガイドローラ１２は、詳細に図示していないが、ローラホルダ１４に内包されているベアリングを介してローラホルダ１４の一端側に回転自在に支持されている。 A plurality of roller holders 14 are arranged radially around the pass line 3, and in this embodiment, for example, three roller holders 14 are arranged at intervals of 120 degrees. The roller holder 14 is formed in a lever shape in which one end side is bent toward the pass line 3. The roller holder 14 is urged between one end side and the rotation support shaft 13 in a direction in which the roller holder 14 opens with respect to the pass line 3 by the elastic force of the coil spring 15. That is, the coil spring 15 is configured as a first elastic member that is interposed between the roller holder 14 and the frame 11 and applies a rotational force to the roller holder 14 in a direction in which the guide roller 12 is separated from the pass line 3.

　この状態で、結合部材２３は回転させずに、ばね用ナット３５を矢印Ａのように回転させて、ばね用ナット３５を結合部材２３に対して相対移動させる。その結果、ばね用ナット３５の凹部３２の底３２ａと結合部材２３の大径筒部２２の底との距離Ｌｓが変化するので、底３２ａと接触しているクッション軸２６ａのフランジ部２５と、大径筒部２２の底との距離が変化する。このことで、圧縮ばね２７の長さはＬｓと等しいので、Ｌｓを調整することで、圧縮ばね２７の長さも調整でき、圧縮ばね２７の弾性力の調整が可能である。よって、ばね用ナット３５と結合部材２３との相対位置の調整によりガイドローラ１２の圧延材の保持力の調整が可能である。 FIG. 8A shows a pre-stage for adjusting the opening degree and the holding force. At this time, the length Ls of the compression spring 27, that is, the distance Ls between the flange portion 25 of the cushion shaft 26a and the bottom of the large-diameter tubular portion 22 is Ls0, the center of the rotary support shaft 13 and the tip of the cushion portion 26 (pressure metal). Let L0 be the distance L from the surface of the member 26b on the receiving surface 11a side).
In this state, the spring nut 35 is rotated as shown by the arrow A without rotating the coupling member 23, and the spring nut 35 is relatively moved with respect to the coupling member 23. As a result, the distance Ls between the bottom 32a of the recess 32 of the spring nut 35 and the bottom of the large-diameter tubular portion 22 of the coupling member 23 changes, so that the flange portion 25 of the cushion shaft 26a in contact with the bottom 32a and the flange portion 25 The distance from the bottom of the large-diameter tubular portion 22 changes. As a result, since the length of the compression spring 27 is equal to Ls, the length of the compression spring 27 can also be adjusted by adjusting Ls, and the elastic force of the compression spring 27 can be adjusted. Therefore, the holding force of the rolled material of the guide roller 12 can be adjusted by adjusting the relative positions of the spring nut 35 and the coupling member 23.
　図８（ｂ）は、圧縮ばね２７の長さが、図８（ａ）の状態における長さＬｓ０よりも短い長さＬｓ１となった状態を示している。圧縮ばね２７の長さＬｓが短くなるようばね用ナット３５と結合部材２３との位置を変更すると、クッション部２６の先端（プレッシャーメタル部材２６ｂの受け面１１ａ側の面）と回転支持軸１３との距離Ｌが、図８（ａ）の状態よりも短い長さＬ１となる。ローラホルダ１４には、コイルばね１５により、常にガイドローラ１２がパスライン３から離間する方向への力が作用しており、この力を受け面１１ａが受けているため、クッション部２６の先端と受け面１１ａとの接触状態が保たれるよう、ローラホルダ１４は回転支持軸１３を中心として回転する。図８（ｂ）中の一点鎖線で示すローラホルダ１４およびガイドローラ１２は図８（ａ）と同じ位置のローラホルダ１４、ガイドローラ１２を、実線で示すローラホルダ１４およびガイドローラ１２は図８（ａ）の状態から回転後のローラホルダ１４、ガイドローラ１２を示している。 FIG. 8B shows a state in which the length of the compression spring 27 is a length Ls1 shorter than the length Ls0 in the state of FIG. 8A. When the positions of the spring nut 35 and the coupling member 23 are changed so that the length Ls of the compression spring 27 is shortened, the tip of the cushion portion 26 (the surface of the pressure metal member 26b on the receiving surface 11a side) and the rotation support shaft 13 are formed. The distance L is a length L1 shorter than the state shown in FIG. 8 (a). A force is always acting on the roller holder 14 in the direction in which the guide roller 12 is separated from the pass line 3 by the coil spring 15, and this force is received by the surface 11a. The roller holder 14 rotates about the rotation support shaft 13 so that the contact state with the receiving surface 11a is maintained. The roller holder 14 and the guide roller 12 shown by the alternate long and short dash line in FIG. 8B are the roller holder 14 and the guide roller 12 at the same positions as those in FIG. 8A, and the roller holder 14 and the guide roller 12 shown by the solid line are shown in FIG. The roller holder 14 and the guide roller 12 after rotation from the state of (a) are shown.
　次に、ガイドローラ１２の開度調整を行う。すなわち、パスライン３とガイドローラ１２の周面との距離Ｌｐの調整を行う。図９（ａ）の点線で示すガイドローラ１２、ローラホルダ１４、支持ユニット２０は、それぞれ、図８（ｂ）に示すものと同一の位置にある状態を示す。結合部材２３の他端側（図９（ａ）中の左側）の端面に設けている溝にドライバ等の工具を噛ませて、支持ユニット２０の結合部材２３を矢印Ｂのように回転させると、結合部材２３とローラホルダ１４とがその結合部において相対移動し、その結果、ローラホルダ１４と結合部材２３との結合部からクッション部２６の先端までの距離Ｌｔが変化する。図９（ａ）においては、この距離Ｌｔが、点線で示すガイドローラ１２、ローラホルダ１４、支持ユニット２０の状態ではＬｔ１であり、これに対して、結合部材２３とローラホルダ１４とがその結合部において相対移動して、実線で示すガイドローラ１２、ローラホルダ１４、支持ユニット２０の状態となると、Ｌｔ２（＞Ｌｔ１）となることを示している。距離Ｌｔが変化すると、その変化に応じて回転支持軸１３からクッション部２６先端までの距離Ｌが変化するので、ローラホルダ１４が回転支持軸１３を中心に回転し、パスライン３とガイドローラ１２の周面との距離Ｌｐが変化する。よって、結合部材２３をローラホルダ１４に対して相対移動させることで、ガイドローラ１２の開度の調整が可能である。なお、結合部材２３をローラホルダ１４に対して相対移動させる際には、ばね用ナット３５と結合部材２３とは相対移動させず、圧縮ばね２７の長さＬｓが変化しないようにすることで、保持力は一定に保つ。 Next, the opening degree of the guide roller 12 is adjusted. That is, the distance Lp between the pass line 3 and the peripheral surface of the guide roller 12 is adjusted. The guide roller 12, the roller holder 14, and the support unit 20 shown by the dotted line in FIG. 9 (a) are in the same positions as those shown in FIG. 8 (b), respectively. When a tool such as a screwdriver is bitten into the groove provided on the other end side (left side in FIG. 9A) of the coupling member 23 and the coupling member 23 of the support unit 20 is rotated as shown by an arrow B. , The coupling member 23 and the roller holder 14 move relative to each other at the coupling portion, and as a result, the distance Lt from the coupling portion between the roller holder 14 and the coupling member 23 to the tip of the cushion portion 26 changes. In FIG. 9A, this distance Lt is Lt1 in the state of the guide roller 12, the roller holder 14, and the support unit 20 shown by the dotted lines, whereas the coupling member 23 and the roller holder 14 are coupled to each other. It is shown that Lt2 (> Lt1) is obtained when the guide roller 12, the roller holder 14, and the support unit 20 are moved relative to each other and are shown by the solid line. When the distance Lt changes, the distance L from the rotary support shaft 13 to the tip of the cushion portion 26 changes according to the change, so that the roller holder 14 rotates around the rotary support shaft 13, and the pass line 3 and the guide roller 12 The distance Lp from the peripheral surface of the surface changes. Therefore, the opening degree of the guide roller 12 can be adjusted by moving the coupling member 23 relative to the roller holder 14. When the coupling member 23 is relatively moved with respect to the roller holder 14, the spring nut 35 and the coupling member 23 are not relatively moved, and the length Ls of the compression spring 27 is not changed. Keep the holding power constant.
　なお、圧縮ばね２７はその弾性力が、上記した弾性力調整機能の調整範囲内のいずれの場合であっても、コイルばね１５の弾性力よりも十分大きな値となっている。圧縮ばね２７を圧縮する力は、圧延材１をガイドローラ１２に接触する前段階（以下、通材前段階と云う）においては、コイルばね１５がローラホルダ１４を回転させようとする力と、受け面１１ａがクッション部２６を介してこの力を受ける反作用の力とである。圧縮ばね２７の弾性力がコイルばね１５の弾性力よりも十分に大きくなっているので、通材前段階においては、圧縮ばね２７の弾性力により、クッション軸２６ａのフランジ部２５が、ばね用ナット３５の凹部３２の底３２ａと接する状態となる。すなわち、クッション部２６のばね用ナット３５からの突出長さが、突出限度の最大の値となる。 The elastic force of the compression spring 27 is sufficiently larger than the elastic force of the coil spring 15 in any case within the adjustment range of the elastic force adjusting function described above. The force for compressing the compression spring 27 is the force with which the coil spring 15 tries to rotate the roller holder 14 in the stage before the rolled material 1 comes into contact with the guide roller 12 (hereinafter referred to as the material passing stage). This is a reaction force in which the receiving surface 11a receives this force via the cushion portion 26. Since the elastic force of the compression spring 27 is sufficiently larger than the elastic force of the coil spring 15, in the pre-material threading stage, the elastic force of the compression spring 27 causes the flange portion 25 of the cushion shaft 26a to have a spring nut. It is in contact with the bottom 32a of the recess 32 of 35. That is, the protrusion length of the cushion portion 26 from the spring nut 35 is the maximum value of the protrusion limit.
　以上で、本実施形態における圧延材誘導装置１０の初期設定は完了する。図９（ｂ）は、圧延材１が圧延材誘導装置１０のガイドローラ１２に噛込んだ際に、ガイドローラ１２の開度が圧延材１の径やパスライン３からのずれに応じて大きくなる様子を示している。図９（ｂ）中の点線で示すガイドローラ１２およびローラホルダ１４は、初期設定状態における位置（図９（ａ）における実線で示すガイドローラ１２、ローラホルダ１４と同一位置）を示しており、図９（ｂ）中の実線で示すガイドローラ１２およびローラホルダ１４は、圧延材１が噛込んだことにより、開度が大きくなった時の位置を示している。図９（ｂ）に示すものでは、噛込み時は初期設定に対してガイドローラ１２の開度はΔＬｐだけ変化している。この開度の変化にともない、ローラホルダ１４が回転支持軸１３を中心に回転すると、支持ユニット２０の結合部材２３およびばね用ナット３５がローラホルダ１４とともに回転する。すると、結合部材２３の大径筒部２２の底が受け面１１ａ側へと移動し、一方、クッション部２６は受け面１１ａと接触していて移動できないので、圧縮ばね２７は圧縮される。図９（ｂ）中の長さｄが、ローラホルダ１４の開度変化にともなう、圧縮ばね２７の圧縮長さである。圧縮ばね２７は、結合部材２３を介してローラホルダ１４に対して、ガイドローラ１２の開度を小さくする向きに弾性力を発生させているので、この弾性力に応じたガイドローラ１２による圧延材１の保持力を維持できる。 This completes the initial setting of the rolled material guidance device 10 in this embodiment. In FIG. 9B, when the rolled material 1 is engaged with the guide roller 12 of the rolled material guiding device 10, the opening degree of the guide roller 12 increases according to the diameter of the rolled material 1 and the deviation from the pass line 3. It shows how it becomes. The guide roller 12 and the roller holder 14 shown by the dotted line in FIG. 9B indicate the positions in the initial setting state (the same positions as the guide roller 12 and the roller holder 14 shown by the solid line in FIG. 9A). The guide roller 12 and the roller holder 14 shown by the solid line in FIG. 9B show the positions when the opening degree is increased due to the rolling material 1 being caught. In the one shown in FIG. 9B, the opening degree of the guide roller 12 changes by ΔLp with respect to the initial setting at the time of biting. When the roller holder 14 rotates about the rotation support shaft 13 with this change in opening degree, the coupling member 23 of the support unit 20 and the spring nut 35 rotate together with the roller holder 14. Then, the bottom of the large-diameter tubular portion 22 of the coupling member 23 moves toward the receiving surface 11a, while the cushion portion 26 is in contact with the receiving surface 11a and cannot move, so that the compression spring 27 is compressed. The length d in FIG. 9B is the compression length of the compression spring 27 as the opening degree of the roller holder 14 changes. Since the compression spring 27 generates an elastic force with respect to the roller holder 14 via the coupling member 23 in a direction to reduce the opening degree of the guide roller 12, the rolled material by the guide roller 12 corresponding to the elastic force. The holding power of 1 can be maintained.
　一実施形態に係る圧延材誘導装置１０では、パスライン３を通過する圧延材１にガイドローラ１２が接触し、このガイドローラ１２の接触により圧延材１を圧延機２に誘導する。圧延材１がガイドローラ１２に接触すると、圧延材１の寸法精度のバラツキや、圧延材１の位置ずれ等により、回転支持軸１３を中心にしてローラホルダ１４の一端側がパスライン３から離れる方向に移動し、ローラホルダ１４の他端側が結合部材２３の大径筒部２２をフレーム１１の受け面１１ａに向かって押圧する。そして、この押圧力により、支持ユニット２０の圧縮ばね２７が伸縮し、ローラホルダ１４の他端側がフレーム１１の受け面１１ａに向かって移動する。すなわち、一実施形態に係る圧延材誘導装置１０は、ガイドローラ１２が圧延材１に接触しているときにガイドローラ１２に負荷される荷重を支持ユニット２０の圧縮ばね２７で吸収して緩和することができ、ガイドローラ１２に内包されているベアリングへの負荷を軽減できる。これにより、一定以上の応力発生時においてベアリングに生じる焼き付きなどの不具合を抑制でき、ガイドローラ１２の回転不良により圧延材１に疵が発生することも抑制できる。 In the rolled material guiding device 10 according to the first embodiment, the guide roller 12 comes into contact with the rolled material 1 passing through the pass line 3, and the rolling material 1 is guided to the rolling mill 2 by the contact of the guide roller 12. When the rolled material 1 comes into contact with the guide roller 12, the direction in which one end side of the roller holder 14 is separated from the pass line 3 around the rotation support shaft 13 due to variations in the dimensional accuracy of the rolled material 1 and misalignment of the rolled material 1. The other end side of the roller holder 14 presses the large-diameter tubular portion 22 of the coupling member 23 toward the receiving surface 11a of the frame 11. Then, the pressing force causes the compression spring 27 of the support unit 20 to expand and contract, and the other end side of the roller holder 14 moves toward the receiving surface 11a of the frame 11. That is, the rolled material guidance device 10 according to one embodiment absorbs and relaxes the load applied to the guide roller 12 when the guide roller 12 is in contact with the rolled material 1 by the compression spring 27 of the support unit 20. This makes it possible to reduce the load on the bearing contained in the guide roller 12. As a result, it is possible to suppress problems such as seizure that occur in the bearing when stress is generated above a certain level, and it is also possible to suppress the occurrence of defects in the rolled material 1 due to poor rotation of the guide roller 12.
　また、支持ユニット２０は、圧縮ばね２７の弾性力を調整する弾性力調整機能と、パスライン３に対してガイドローラ１２の位置を調整する位置調整機能と、を備えている。そして、圧縮ばね２７の弾性力は、ばね用ナット３５を回転させることにより、変更することができる。一方、パスライン３に対するガイドローラ１２の位置は、結合部材２３を回転させることにより、圧縮ばね２７の弾性力を変更することなく、変更することができる。したがって、一実施形態に係る圧延材誘導装置１０は、圧縮ばね２７の弾性力調整と、パスライン３に対するガイドローラ１２の位置調整とを個別に行うことができる。よって、フレーム本体に調節機構を設ける必要もなく、装置構成が大掛かりとなることもない。 Further, the support unit 20 has an elastic force adjusting function for adjusting the elastic force of the compression spring 27 and a position adjusting function for adjusting the position of the guide roller 12 with respect to the pass line 3. The elastic force of the compression spring 27 can be changed by rotating the spring nut 35. On the other hand, the position of the guide roller 12 with respect to the pass line 3 can be changed by rotating the coupling member 23 without changing the elastic force of the compression spring 27. Therefore, the rolled material guidance device 10 according to the embodiment can individually adjust the elastic force of the compression spring 27 and the position of the guide roller 12 with respect to the pass line 3. Therefore, it is not necessary to provide an adjusting mechanism in the frame body, and the device configuration does not become large.
　さらに、複数のガイドローラ１２をパスライン３の周りに複数配置する場合においても、個々のガイドローラ１２について、上述の一実施形態のような構成とすることで、個々のガイドローラ１２の開度調整を個別に行うことはできる。よって、例えば、ガイドローラ１２の摩耗度の違い等に対応するために、ガイドローラ１２毎に開度調整を行う必要がある場合にも対応できる。
　また、プレッシャーメタル部材２６ｂは、クッション軸２６ａの一端側の端面に着脱自在に装着されているので、プレッシャーメタル部材２６ｂの摩耗時の交換を容易に行うことができる。 Further, even when a plurality of guide rollers 12 are arranged around the pass line 3, the opening degree of each guide roller 12 can be opened by configuring the individual guide rollers 12 as in the above-described embodiment. Adjustments can be made individually. Therefore, for example, in order to cope with the difference in the degree of wear of the guide rollers 12, it is possible to cope with the case where it is necessary to adjust the opening degree for each guide roller 12.
Further, since the pressure metal member 26b is detachably attached to the end surface of the cushion shaft 26a on one end side, the pressure metal member 26b can be easily replaced when it is worn.
　また、プレッシャーメタル部材２６ｂは、フレーム１１の受け面１１ａと当接する面３７ａが凸面状になっている。このため、支持ユニット２０がフレーム１１の受け面１１ａに対して若干斜めになっていても、支持ユニット２０をフレーム１１に支持させることができる。なお、クッション部２６として、その先端の摩耗時等の場合に、クッション部２６ごと交換してもよい場合は、クッション部２６として、プレッシャーメタル部材２６ｂとクッション軸２６ａとが一体に構成されていてもよい。 Further, in the pressure metal member 26b, the surface 37a that comes into contact with the receiving surface 11a of the frame 11 is convex. Therefore, even if the support unit 20 is slightly inclined with respect to the receiving surface 11a of the frame 11, the support unit 20 can be supported by the frame 11. If the cushion portion 26 may be replaced together with the cushion portion 26 when the tip of the cushion portion 26 is worn, the pressure metal member 26b and the cushion shaft 26a are integrally formed as the cushion portion 26. May be good.
　次に、本発明の別の実施形態について説明する。図１０は本発明の別の実施形態に係る圧延材誘導装置１１０を示す。図１０に示す圧延材誘導装置１１０は、図２～図９に示すものに対して、支持ユニットの構成が異なっている。その他の構成は、図２～図９に示す実施形態と同様である。図１０に示す実施形態において、支持ユニット１２０は、結合部材１２３が筒状部材１２３ａと筒状部材１２３ｂとからなる。筒状部材１２３ａは、一端にフランジ部１２２を有する。筒状部材１２３ａの筒状の部分は、結合部材１２３の全長にわたっており、つまり、筒状部材１２３ａは軸方向に貫通する貫通孔を有している。筒状部分の外周の一部には、雄ねじ部１４１がある。この筒状部材１２３ａの雄ねじ部１４１と、ローラホルダ１４の雌ねじ部４３とが噛み合うことで、筒状部材１２３ａとローラホルダ１４とがねじ結合している。ここで、フランジ部１２２が受け面１１ａ側となるように、結合部材１２３とローラホルダ１４とは結合している。筒状部材１２３ｂは、貫通孔を有する部材であり、一端側（受け面１１ａ側となる側）には、筒状部材１２３ａに設けた雄ねじ部１４１と噛み合う雌ねじ部を有する。そして、筒状部材１２３ａと筒状部材１２３ｂがねじ結合されて、一体の結合部材１２３を構成している。筒状部材１２３ｂは、結合部材１２３のローラホルダ１４に対する位置ずれを防止する機能も有しており、この筒状部材１２３ｂを締め付けてローラホルダ１４に接触させることによって筒状部材１２３ａのローラホルダ１４に対する回動をロックする。 Next, another embodiment of the present invention will be described. FIG. 10 shows a rolled material guidance device 110 according to another embodiment of the present invention. The rolled material guidance device 110 shown in FIG. 10 has a different support unit configuration from those shown in FIGS. 2 to 9. Other configurations are the same as those of the embodiments shown in FIGS. 2 to 9. In the embodiment shown in FIG. 10, in the support unit 120, the connecting member 123 includes a tubular member 123a and a tubular member 123b. The tubular member 123a has a flange portion 122 at one end. The tubular portion of the tubular member 123a extends over the entire length of the coupling member 123, that is, the tubular member 123a has a through hole penetrating in the axial direction. A male screw portion 141 is provided on a part of the outer circumference of the tubular portion. The male screw portion 141 of the tubular member 123a and the female screw portion 43 of the roller holder 14 mesh with each other, so that the tubular member 123a and the roller holder 14 are screwed together. Here, the coupling member 123 and the roller holder 14 are coupled so that the flange portion 122 is on the receiving surface 11a side. The tubular member 123b is a member having a through hole, and has a female screw portion that meshes with a male screw portion 141 provided on the tubular member 123a on one end side (the side that becomes the receiving surface 11a side). Then, the tubular member 123a and the tubular member 123b are screwed together to form an integral connecting member 123. The tubular member 123b also has a function of preventing the coupling member 123 from being displaced with respect to the roller holder 14, and by tightening the tubular member 123b and bringing it into contact with the roller holder 14, the roller holder 14 of the tubular member 123a is brought into contact with the roller holder 14. Lock the rotation with respect to.
　結合部材１２３の貫通孔には、クッション軸１２６ａが結合部材１２３に対して摺動可能に挿入されている。クッション軸１２６ａは一端にフランジ部１２５を有し、このフランジ部が受け面１１ａ側に位置するよう、配置される。クッション軸１２６ａの先端（受け面１１ａ側）にはプレッシャーメタル部材１２６ｂが固定されている。プレッシャーメタル部材１２６ｂの受け面１１ａ側の面１３７ａが、受け面１１ａと当接する面であり、この面１３７ａは、凸面状になっている。クッション軸１２６ａとプレッシャーメタル部材１２６ｂとで、クッション部１２６を構成している。 The cushion shaft 126a is slidably inserted into the through hole of the coupling member 123 with respect to the coupling member 123. The cushion shaft 126a has a flange portion 125 at one end, and is arranged so that the flange portion is located on the receiving surface 11a side. A pressure metal member 126b is fixed to the tip of the cushion shaft 126a (on the receiving surface 11a side). The surface 137a on the receiving surface 11a side of the pressure metal member 126b is a surface that comes into contact with the receiving surface 11a, and this surface 137a has a convex shape. The cushion shaft 126a and the pressure metal member 126b constitute the cushion portion 126.
　クッション軸１２６ａのフランジ部１２５と結合部材１２３のフランジ部１２２との間に、圧縮ばね２７（本発明における第２の弾性部材に相当）が配置される。圧縮ばね２７は、一端側が結合部材１２３のフランジ部１２２に当接して支持され、他端側がクッション軸１２６ａのフランジ部１２５に当接して支持された状態でクッション軸１２６ａの外周に設けられたコイル状のばねである。
　クッション軸１２６ａは、圧縮ばね２７の両端がそれぞれフランジ部１２５、フランジ部１２２に接触した状態において、結合部材１２３のフランジ部１２２がない側の端部１２３ｃから突出している。そして、この状態における、クッション軸１２６ａの外周の端部１２３ｃに径方向で対向する部分を含む領域には、雄ねじ部１３１が設けられている。 A compression spring 27 (corresponding to the second elastic member in the present invention) is arranged between the flange portion 125 of the cushion shaft 126a and the flange portion 122 of the coupling member 123. The compression spring 27 is a coil provided on the outer periphery of the cushion shaft 126a in a state where one end side is in contact with the flange portion 122 of the coupling member 123 and is supported, and the other end side is in contact with and supported by the flange portion 125 of the cushion shaft 126a. It is a shaped spring.
The cushion shaft 126a projects from the end portion 123c of the coupling member 123 on the side where the flange portion 122 does not exist, in a state where both ends of the compression spring 27 are in contact with the flange portion 125 and the flange portion 122, respectively. In this state, the male screw portion 131 is provided in the region including the portion that faces the end portion 123c of the outer periphery of the cushion shaft 126a in the radial direction.
　図１０中の符号１３５はばね用ナットであり、このばね用ナットが保持部材１３５である。ばね用ナット１３５は、結合部材１２３の端部（筒状部材１２３ｂの端部）１２３ｃに軸方向で対向して配置され、ばね用ナット１３５の雌ねじ部１３３が、クッション軸１２６ａに設けた雄ねじ部１３１と噛合う。クッション軸１２６ａに端部１２３ｃから突出した部分にばね用ナットを嵌め、ばね用ナット１３５が結合部材１２３の端部１２３ｃに接触し、さらに、圧縮ばね２７が圧縮されるまで締め込む。この時の、ばね用ナット１３５の締め込み量を調整することで、圧縮ばね２７の長さを調整することができ、これにより、圧縮ばね２７の弾性力を調整できる。クッション部１２６は、圧縮ばね２７の弾性力により受け面１１ａ側へと移動する力を受けるが、ばね用ナット１３５の結合部材１２３に対向する側の端面が、結合部材と噛み合って、その移動を拘束する。つまり、ばね用ナット１３５の結合部材１２３側の端面１３５ａが、結合部材１２３と噛み合って、クッション部１２６の結合部材１２３からの摺動方向の突出量を制約する係合部である。また、雌ねじ部１３３が、係合部１３５ａが結合部材と噛合っている状態における圧縮ばね（第2の弾性部材）２７の弾性力を調整する調整ねじとなっている。ナット４７は、ばね用ナット１３５のクッション軸１２６ａに対する位置ずれを防止用のナットであり、このナット４７を締め付けることによってばね用ナット１３５のクッション軸１２６ａに対する回動をロックする。 Reference numeral 135 in FIG. 10 is a spring nut, and this spring nut is a holding member 135. The spring nut 135 is arranged so as to face the end portion (end portion of the tubular member 123b) 123c of the coupling member 123 in the axial direction, and the female thread portion 133 of the spring nut 135 is provided on the cushion shaft 126a. Engage with 131. A spring nut is fitted into the cushion shaft 126a at a portion protruding from the end portion 123c, and the spring nut 135 is brought into contact with the end portion 123c of the coupling member 123 and further tightened until the compression spring 27 is compressed. By adjusting the tightening amount of the spring nut 135 at this time, the length of the compression spring 27 can be adjusted, whereby the elastic force of the compression spring 27 can be adjusted. The cushion portion 126 receives a force that moves toward the receiving surface 11a due to the elastic force of the compression spring 27, but the end surface of the spring nut 135 on the side facing the coupling member 123 meshes with the coupling member to move the cushion portion 126. to restrict.
