Claims (1)
- 鋼帯の幅方向の両側縁を丸刃の上刃及び下刃により剪断するサイドトリマー用剪断刃の欠損を検出する装置であって、
サイドトリマー用剪断刃が設けられた箇所よりも鋼帯の進行方向側の上部に位置するベース部材にそれぞれ外向きに設けられ、前記鋼帯の剪断箇所で発生した音を集音する左右一対のマイクと、
鋼帯の寸法、硬さ、ライン速度などの運転条件の組み合わせ毎に記憶させておいた正常剪断時の音の音圧と、前記マイクで集音した音の音圧との差を算出する音圧解析手段と、
当該音庄解析手段で算出した音圧差が4dBを超えた場合に、前記サイドトリマー用剪断刃に欠損が発生したと判定する欠損有無判定手段とを備えたことを特徴とするサイドトリマー用剪断刃の欠損検出装置。
