本発明は、圧延帯鋼の巻取装置に装着されているラッパ
ーローラを研磨するために用いるラッパーローラ研磨用
治具に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wrapper roller polishing jig used for polishing a wrapper roller installed in a winding device for rolled steel strip.
（従来技術とその問題点）
帯鋼の製造ラインにおいて、その圧延工程の最終地点に
は、既に前段の工程で所定の厚みにまで圧延された帯鋼
を巻取るための装置が備えつけられている。この圧延帯
鋼の巻取装置の帯巻取部は一般に第５図に示すような構
造になっている。第５図は、巻取装置の巻取部を装置の
軸方向から眺めたときの各要素の位置関係を説明するた
めの概念図である。(Prior art and its problems) In a steel strip manufacturing line, the final point of the rolling process is equipped with a device for winding up the steel strip that has already been rolled to a predetermined thickness in the previous process. . The strip winding section of this rolled steel strip winding device generally has a structure as shown in FIG. FIG. 5 is a conceptual diagram for explaining the positional relationship of each element when the winding section of the winding device is viewed from the axial direction of the device.
図において、マンドレルｌは装置の中心部に少なくとも
巻取るべき帯鋼の幅に相当する長さだけ突出している。In the figure, the mandrel l projects from the center of the device by at least a length corresponding to the width of the steel strip to be wound.
マンドレル１は所定の肉厚を有する４個の拡縮用セグメ
ントから成りその一端は図示しない駆動機構と接続され
、他の自由端を拡縮構造とし、全体が径方向に縮拡可能
であるようになっている。The mandrel 1 is made up of four expansion/contraction segments each having a predetermined wall thickness, one end of which is connected to a drive mechanism (not shown), and the other free end of which has an expansion/contraction structure, so that the entire segment can be expanded/contracted in the radial direction. ing.
マンドレルｌを矢線ｐ方向に回転せしめることにより、
ガイドローラ２上を移送されてきた圧延帯鋼３がマンド
レルｌの周囲に連続的に巻取られていく、マンドレル１
の周囲には通常４個の表面平滑なラッパローラ４ａ〜４
ｄが、マンドレル１の突出長と同じ長さで突出して配設
されている。By rotating the mandrel l in the direction of the arrow p,
The rolled steel strip 3 that has been transferred on the guide rollers 2 is continuously wound around the mandrel 1.
There are usually four wrapper rollers 4a to 4 with smooth surfaces around the
d is arranged to protrude with the same length as the protrusion length of the mandrel 1.
これらのラッパローラ４ａ〜４ｄは、それぞれに付設さ
れている駆動機構により自らも例えば矢線Ｐ方向に回転
し、かつ、図示しない空圧機構などによりマンドレル１
の径方向に移動可能となっており、巻取られている圧延
帯鋼をその巻取り開始時および巻取り終了時に軽く押圧
して、マンドレル１上に巻取られた帯鋼の巻戻りを防止
している。These trumpet rollers 4a to 4d rotate themselves, for example, in the direction of the arrow P by a drive mechanism attached to each one, and also rotate the mandrel 1 by a pneumatic mechanism (not shown) or the like.
It is movable in the radial direction of the mandrel 1 and lightly presses the rolled steel strip being wound at the start and end of winding to prevent the steel strip wound on the mandrel 1 from unwinding. are doing.
圧延された帯鋼３の所定長さがマンドレル１に巻取られ
ると、帯鋼の巻戻り防止処置を施したのち押圧動作を停
止し、マンドレル１を縮径し帯鋼の巻取り束をマンドレ
ル１から取り外す。When a predetermined length of the rolled steel strip 3 is wound onto the mandrel 1, measures are taken to prevent the steel strip from unwinding, the pressing operation is stopped, the diameter of the mandrel 1 is reduced, and the rolled bundle of steel strips is rolled onto the mandrel. Remove from 1.
ところで、この帯鋼の巻取り過程でラッパーローラの表
面に疵がつき、表面の平滑性が損なわれることがある。Incidentally, during the process of winding up the steel strip, the surface of the wrapper roller may be scratched and the smoothness of the surface may be impaired.
このラッパーローラ表面への疵は圧延帯鋼の巻取り開始
時に多発する。それは、巻取るべき帯鋼の先端がラッパ
ーローラ４ａから４ｄへと順次激突していくからである
。This flaw on the surface of the wrapper roller frequently occurs at the beginning of winding of the rolled steel strip. This is because the tip of the steel strip to be wound collides with the wrapper rollers 4a to 4d in sequence.
ひとたびラッパーローラの表面に疵がつくと、これらに
押圧されながら巻取られていく帯鋼の表面にこの疵が連
続的に転写されて帯鋼にも疵がつき、結果として巻取ら
れた帯鋼の巻取り束は不良品になることがある。Once a flaw is formed on the surface of the wrapper roller, this flaw is continuously transferred to the surface of the steel strip that is being wound up while being pressed by these rollers, causing flaws in the steel band as well. Steel winding bundles may be defective.
このため、巻取装置の運転に当たっては、常時、作業者
がラッパーローラ表面の疵発生の有無を観察・点検し、
かつ、かなりの頻度でラッパーローラの表面を研磨する
作業が行われている。Therefore, when operating the winding device, the operator always observes and inspects the surface of the wrapper roller for any flaws.
In addition, the surface of the wrapper roller is polished quite frequently.
従来の上記研磨作業は基本的には人力作業である。すな
わち、ラッパーローラ表面の研磨に際してはまず装置全
体の運転を停止したのち、マンドレル１と各ラフパーロ
ーラ４ａ〜４ｄが形成する空間に作業者は身体を入れ、
手に持つ例えば電動グラインダで各ラフパーローラの表
面を順次研磨していくのである。The conventional polishing work described above is basically a manual work. That is, when polishing the surface of the wrapper roller, the operator first stops the operation of the entire apparatus, then inserts his or her body into the space formed by the mandrel 1 and each of the rough rollers 4a to 4d.
The surface of each rough par roller is sequentially polished using, for example, an electric grinder held in hand.
しかしながら、上記した研磨作業は足場の悪い狭所で進
められるため危険な作業である。また、グラインダを用
いた手作業により個々のラッパーローラを順次研磨する
ので、作業には比較的長時間を要し、また研磨後の表面
の平滑性にバラツキが発生し易い。However, the polishing work described above is dangerous because it is carried out in a narrow space with poor footing. Furthermore, since the individual wrapper rollers are manually polished one after another using a grinder, the work requires a relatively long time, and the smoothness of the surface after polishing is likely to vary.
本発明は、上記した問題を一挙に解決することができ、
均一な表面研磨を短時間でかつ安全に行うためのラッパ
ーローラ研磨用治具の提供を目的とする。The present invention can solve the above problems all at once,
The purpose of the present invention is to provide a wrapper roller polishing jig for safely and quickly polishing a uniform surface.
（問題点を解決するための手段）

研磨する研磨帯とから成ることを特徴とする。(Means for Solving the Problems) The wrapper roller polishing jig of the present invention includes a drum body that is removably fitted onto a mandrel of a rolled strip winding device, and a drum body that covers the outer peripheral surface of the drum body. and a polishing band which is fixed and polishes the wrapper roller.
（作用）
マンドレルを縮径して本発明の治具を嵌着したのち拡径
してマンドレルに治具を固定する。治具の研磨帯にラッ
パーローラを軽く押圧せしめる。(Operation) After reducing the diameter of the mandrel and fitting the jig of the present invention, the diameter is expanded to fix the jig to the mandrel. Lightly press the wrapper roller against the polishing band of the jig.
その状態でマンドレルとラッパーローラ間で相対的な回

ば、各ラッパーローラの研磨にバラツキが生ずることは
ない。In this state, relative rotational movement is performed between the mandrel and the wrapper roller. Since the wrapper roller rotates while being pressed at the pressing point by the roller 7 of the polishing band of the jig, the surfaces of the four wrapper rollers are simultaneously polished. If each wrapper roller applies equal pressure to the polishing band, there will be no variation in the polishing of each wrapper roller.
研磨終了後は、ラッパーローラの回転を停止しそれらを
治具から離隔せしめ、マンドレルを縮径して治具をマン
ドレルから抜き取ればよい。After polishing is completed, the rotation of the wrapper rollers is stopped to separate them from the jig, the diameter of the mandrel is reduced, and the jig is removed from the mandrel.
