設備停止時間に見合ったルーパ設備を有しているが、ル
ーパの長さを出来るだけ短くすること、即ち入側停止時
間を極力少なくすることが、設備費の低減とともに連続
ラインの生産性向上の大きなポイントである。For this reason, continuous lines usually have looper equipment that is commensurate with the equipment down time on the entry side, but it is important to make the length of the looper as short as possible, that is, to minimize the down time on the entry side. This is a key point in reducing equipment costs and improving productivity on continuous lines.

定完了したことが確認される。First, when information such as the thickness and width of the steel plate to be notched, the depth of cut, and the position of the welded part is transmitted from the host computer 16 to the control device 15, the control device 15 compares the transmitted information with the current state. , the height, movement amount, and notching speed of the upper blade 7a are calculated, and the upper blade position adjustment drive device 10. Mobile device 13. Each control signal is sent to the blade rotation drive device 8 to control it. The control status of each part is determined by each position detection sensor 14.
a, 14b, and 14C and fed back to the control device 15, and is controlled to a predetermined value to confirm that the setting is completed.

b is positioned in the width direction by the entry side and exit side plate alignment devices 4a and 4b, respectively, and then the rear end of the leading steel plate 1a and the tip of the trailing steel plate 1b are cut in the welding machine 3, and welding is performed. A welding completion signal is sent to the host computer 16.

取ると、入側通板設備（図示せず）によって鋼板を低速
例えば３０ＩＩｉｐＩ１１程度の速度で移動させるとと
もに、制御装置１５にその速度信号を出力する。When the host computer 16 receives the setting completion signal and the welding completion signal, it moves the steel plate at a low speed, for example, about 30IIipI11, using the entry side threading equipment (not shown), and sends the speed signal to the control device 15. Output.

接部所定位置にノツチングを行う。The control device 15 calculates the activation timing of the blade rotation drive device 8 based on the distance from the welding part 3 and the sheet threading speed, and controls the blade rotation drive device 8 using the control signal to control the notching blades 7 a' and 7 b. It is rotated to notch the welded portion of the moving steel plate at a predetermined position.

１５に対してノツチング待機状態への指令を出力する。When the notching completion signal is detected by the position detection sensor 14d, the control device 15 immediately sends this signal to the host computer 16.
Therefore, the host computer 16 outputs a threading speed acceleration signal to the entry side threading equipment, accelerates the line speed to convey the steel plate at a predetermined operating speed, and sends a signal to the control device 15. Outputs a command to the notching standby state.
制御装置１５は、このノツチング待機状態に基づき刃回

１３を制御して待機状態へ移動させる。Based on this notching standby state, the control device 15 controls the blade rotation drive device 8 and the blade position adjustment drive device 10° moving device 13 to move them to the standby state.
なお、上記実施例では、溶接後に鋼板を低速で搬送する
際、その速度を任意に変化させる場合について述べたが
、これを全ての処理鋼板について一定速度で搬送するよ
うに設定すれば、溶接部のトラッキングは不要となり、
搬送開始から常に一定のタイミングで刃回転駆動装置８
を起動することもできる。In addition, in the above embodiment, when conveying the steel plate at a low speed after welding, the speed was arbitrarily changed, but if this is set so that all processed steel plates are conveyed at a constant speed, the welded part tracking is no longer required,
The blade rotation drive device 8 always rotates at a constant timing from the start of conveyance.
You can also start.
このように構成された溶接装置を鋼板の酸洗設備に適用
したところ、入側設備の停止時間は従来２０秒であった
のに対して、７秒の短縮が実現することができた。When the welding apparatus configured in this manner was applied to pickling equipment for steel plates, the stop time of the entrance equipment was reduced to 7 seconds, compared to the conventional 20 seconds.
通常の酸洗設備のライン速度は２００ｍｐｍ程度である
から、この７秒の短縮はルーバ長さを約２３ｍ短縮する
ことが可能で、それだけ設備費の低減が図ることが可能
である。また、逆にルーパ長さに７秒の余裕を持たせた
設備設計をすれば、設備費の低減はないがライン操業中
入側設備停止時間に余裕ができるから、特に炉設備など
ライン減速や停止が出来ないラインの操業の安定や生産
性の向上が期待される。Since the line speed of normal pickling equipment is about 200 mpm, this reduction of 7 seconds can shorten the louver length by about 23 m, which can reduce equipment costs accordingly. Conversely, if the equipment is designed with a margin of 7 seconds for the looper length, there will be no reduction in equipment costs, but there will be more time to stop the equipment on the entry side during line operation, which will reduce line deceleration, especially for furnace equipment. It is expected to stabilize the operation of lines that cannot be stopped and improve productivity.
