図１において、例えば、欠陥や仕様外れによってスクラップにする鋼帯は、ピンチロール１を介してテンションリール２に巻き取られ鋼帯コイル３としてコイルカー４の上に載置される。
しかし、小径の鋼帯コイル（小コイル）は、鋼帯の剛性によって、ばらけてしまうことがあり危険であった。
In FIG. 1, for example, a steel strip to be scrapped due to defects or out of specification is wound on a tension reel 2 via a pinch roll 1 and placed on a coil car 4 as a steel strip coil 3.
However, the small-diameter steel strip coil (small coil) may be scattered due to the rigidity of the steel strip, which is dangerous.
そこで、本発明は、鋼帯コイルの終端部をスポット溶接して固定する鋼帯コイルの終端部固定装置において、鋼帯を押さえるスナバーロール５と、スポット溶接を行うスポット溶接機とを一体とし、スポット溶接機の溶接ガン８は、前記鋼帯コイル３の中心方向に配置され、該鋼帯コイル３の中心方向に直進して前記鋼帯コイルの終端部をスポット溶接することを特徴とする。

図２に示すように、本実施形態においては、スナバーロール５が、軸方向に３分割されてロール軸に回転自在に搭載されており、分割されたスナバーロール５の間に複数台（本実施形態においては２台）の溶接ガン８を設置し、この溶接ガン８を前記スナバーロール５と接触する鋼帯コイルの外周面に対して進退可能に搭載した移動台６が設置されている。
また、移動台６はスライドガイド７でガイドされ、エアシリンダ９により、スナバーロール５および溶接ガン８を、鋼帯コイルの中心であるテンションリールの軸方向に向かって前進・後退させることができる。
このように、溶接ガン８を鋼帯コイルの中心方向に配置することによって、溶接ガン８を常にコイル外周面に対し直角に押し付けることができるので溶接性が向上するうえ、溶接ガン８を分割されたスナバーロール５の間に複数台設置することにより、鋼帯の幅方向に複数点のスポット溶接を１回の動作で行うことができるので、鋼帯の幅方向に複数回のスポット溶接を行う従来の方法に比べて溶接作業時間を著しく短縮することができる。
FIG. 2 is a diagram illustrating an embodiment in the case where the snubber roll and the welding machine used in the present invention are in the standby position, and is a view taken in the direction of arrow A in FIG. 1.
As shown in FIG. 2, in this embodiment, the snubber roll 5 is divided into three in the axial direction and is rotatably mounted on the roll shaft, and a plurality of snubber rolls 5 are installed between the divided snubber rolls 5 (this embodiment). In this embodiment, two welding guns 8 are installed, and a moving table 6 is installed in which the welding guns 8 are mounted so as to be able to advance and retract with respect to the outer peripheral surface of the steel strip coil in contact with the snubber roll 5.
Further, the movable table 6 is guided by a slide guide 7, and the snubber roll 5 and the welding gun 8 can be advanced and retracted in the axial direction of the tension reel that is the center of the steel strip coil by the air cylinder 9.
Thus, by arranging the welding gun 8 in the center direction of the steel strip coil, the welding gun 8 can always be pressed at right angles to the outer peripheral surface of the coil, so that the weldability is improved and the welding gun 8 is divided. By installing a plurality of units between the snubber rolls 5, spot welding can be performed at a plurality of points in the width direction of the steel strip in one operation, so that spot welding is performed a plurality of times in the width direction of the steel strip. Compared with the conventional method, the welding operation time can be remarkably shortened.
また、スナバーロール５は、通常は巻き取るときの鋼帯を押さえるために使用するが、コイル端を溶接して固定するときには、スポット溶接する際の押さえロールとして使用することができる。このとき、スポット溶接時は鋼帯の密着性を上げて溶接性を向上させるため、一時的にエアシリンダのエアー圧力を上昇させて、鋼帯の押し付け力を増加させることが好ましい。
なお、本発明における鋼帯コイルの終端部固定装置の使用方法を以下に例示する。
まず、鋼帯の巻き取り終了後、スナバーロール５および必用に応じてコイルカー４のサドルによって、鋼帯コイルの外周面を保持する。
次に、テンションリール２を回転させて、コイル終端部をスナバーロール５の位置に合わせるように位置調整する。
そして、前述のように、スナバーロール５の押し付け力を高めた後に、溶接ガン８の電極をコイル外周面に押し付けてスポット溶接を行うことにより、コイル終端の固定に要する操業時間を短縮することができる。
図３は、本発明における鋼帯コイルの終端部固定装置が操業位置にある実施形態を例示する図１のＡ矢視図である。
エアシリンダ９を矢印の方向に伸ばすことによって、移動台６、スナバーロール５、溶接ガン８が一体となって、図２の待機位置から図３の操業位置に移動して、スナバーロール５をコイル外周に接触させて押さえることができる。
図４は、本発明における鋼帯コイルの終端部固定装置に用いる溶接ガンの動作を説明する図であり、左側がスナバーロールとして使用している状態、右側がスポット溶接を行っている状態を示す。
このように、スポット溶接を行うときだけ、溶接電極１０を押し出して電極の先端がコイル外周に接近させてスポット溶接を行うことができる。
The snubber roll 5 is usually used for pressing a steel strip when winding, but can be used as a pressing roll for spot welding when the coil ends are welded and fixed. At this time, in order to improve the weldability by increasing the adhesion of the steel strip at the time of spot welding, it is preferable to increase the pressing force of the steel strip by temporarily increasing the air pressure of the air cylinder.
In addition, the usage method of the termination | terminus part fixing device of the steel strip coil in this invention is illustrated below.
First, after the winding of the steel strip is completed, the outer peripheral surface of the steel strip coil is held by the snubber roll 5 and, if necessary, the saddle of the coil car 4.
Next, the tension reel 2 is rotated, and the position of the coil end portion is adjusted so as to match the position of the snubber roll 5.
As described above, after increasing the pressing force of the snubber roll 5, the operation time required for fixing the coil end can be reduced by pressing the electrode of the welding gun 8 against the coil outer peripheral surface and performing spot welding. it can.
FIG. 3 is a view taken in the direction of the arrow A in FIG. 1 illustrating an embodiment in which the end fixing device for the steel strip coil in the present invention is in the operating position.
By extending the air cylinder 9 in the direction of the arrow, the moving base 6, the snubber roll 5 and the welding gun 8 are integrated and moved from the standby position of FIG. 2 to the operating position of FIG. It can be pressed against the outer periphery.
FIG. 4 is a diagram for explaining the operation of a welding gun used in the steel strip coil terminal end fixing device according to the present invention, in which the left side is used as a snubber roll, and the right side is in a spot welding state. .
Thus, only when spot welding is performed, the welding electrode 10 can be pushed out and the tip of the electrode can be brought close to the outer periphery of the coil for spot welding.
