されるのである。Further, when cutting the metal strip into the metal plate 1, burrs called "returns" are formed at both cut ends of the metal plate 1 as shown in FIG. In order to prevent damage to the surface of the metal plate 1 due to, the protective paper 2 needs to be longer than the metal plate 1. Therefore, the protective paper 2 interposed in the metal plate 1 sticks out from both ends of the metal plate 1, In addition, the tip of the protective paper 2 is bent and inserted in the plate surface direction of the metal plate 1.
このような状態に保護紙２が介装された金属板１が積層

払い出し上のトラブルを生じやすく、かつ金属板１の前
端にて折れ込んでいる保護紙２を引掛けて払い出す等の
トラブルを発生しやすい。In order to smoothly separate and dispense the stacked metal plates 1 one by one, it is necessary to set the suction positions of the plate suction cups 4 and 5 to both ends of the metal plate 1 as much as possible. When the cups 4 and 5 are moved to the central part of the metal plate 1 and the both ends of the protective paper 2 are absorbed to avoid adsorption, separation of the metal plates 1 from each other is hindered and a plurality of metal plates 1 are simultaneously formed. Adsorb,
Problems in paying out are likely to occur, and problems such as catching and paying out the protective paper 2 folded at the front end of the metal plate 1 are likely to occur.
金属板１と保護紙２とが一緒になってラインへ払い出さ

場合、即刻払い出しを中断してライン内から保護紙２を
取り除く手段を講じればよいが、そのためには、監視作
業員と保護紙除去作業員を常時配置せざる得ず、省力化
に逆行することになる。Further, when the protective paper 2 is also paid out at the time of paying out, it is only necessary to interrupt the paying out immediately and take a means to remove the protective paper 2 from the inside of the line. We have no choice but to always allocate personnel, which goes against labor saving.
またさらに、保護紙２を、吸着、除去する際において
も、金属板１の後端における保護紙２の折れ込みが問題
となる。Further, even when the protective paper 2 is sucked and removed, the folding of the protective paper 2 at the rear end of the metal plate 1 becomes a problem.
すなわち、折れ込み部は、紙吸着カップ７の吸着口に隙
間を生じ、吸着力が低下するため、吸着ミスを生じやす
く、金属板１の上に保護紙２の折れ込み部が引掛かった
状態で払い出してしまい、前記と同様のトラブルを発生
しやすい。That is, since the folded portion forms a gap in the suction port of the paper suction cup 7 and the suction force is reduced, a suction error is likely to occur, and the folded portion of the protective paper 2 is caught on the metal plate 1. Therefore, the same trouble as described above is likely to occur.
