AI • IoTとマシン汚れ防止技術の融合による生産性向上と働き方改革の両立

摘要

Maintech's innovative technology Dryer Surface Passivation (or DSP) has been introduced on over 200 paper machines across the world and become a Global Standard for recycled papermaking. In recycled papermaking, as the deposit levels and profiles on the fabric and rolls often change, it is required to adjust the chemicals and chemical spraying equipment according to the conditions. However, it is dangerous for workers to check the fabric condition inside the dryer hood in a high temperature and humidity environment. Therefore, we have developed an "Intelligent Deposit Control System (IDCS)" utilizing the AI, IoT, image processing, field network and sensing technologies. We report that we have developed a system "phase 1"to optimize chemical dosage according to the deposit conditions by visualization of the deposition on the fabric in the dryer hood with heat resistant cameras and by quantification by use of image processing.%当社は独自に開発した薬品と薬品散布装置を用いて抄紙機の汚れを防止する技術を販売しており，当社のドライパート汚れ防止技術は欠点•断紙対策として国内板紙工場の95%で採用され，国内外で600台以上の薬品散布装置ミストランナー•シャワーランナー力s稼働している.古紙を原料とするリサイクル抄紙においては，古紙原料中の汚れ量の変動，季節要因などによって日々刻々とマシンの汚れ状況が変化しているため，そのつどマシンコンディションゃ汚れ状況を確認して，汚れ防止薬品やマシン洗浄設備の調整が必要となっている.
