- 연속칼라강판의 생산라인에서의 건조작업 자동제어방법에 있어서,생산관리시스템으로부터 강판 소재의 정보를 수집하고, 건조작업 데이터 설정시스템에서 강판의 강종, 강판의 두께, 강판의 색상에 대한 지시값에 대하여 전력비율과 라인속도에 대한 도장 작업 데이터를 계산하며,상기 계산 결과값을 HMI(H㎛an Machine Interface) 터미널에 표시하여 조업자가 확인할 수 있도록 함과 동시에 상기 계산 결과값은 네트워크 허브를 통하여 단위장치 제어 및 데이터 처리용 PLC에 자동으로 설정되게 하는 연속 칼라 강판 생산 라인에서 근적외선을 이용한 건조작업 자동제어방법.
- 연속칼라강판의 생산라인에서의 건조작업 자동제어방법에 있어서,근적외선(NIR)을 이용한 오븐으로 건조하되 특히 습식도료의 건조조건을 시뮬레이션하여 그 결과를 도출하고, 이를 기초로 NIR 오븐의 작업조건을 설정하는 방식으로서 자동설정방식, 수동설정방식과 시뮬레이션 방식의 3가지로 구비하고, 자동설정방법은 작업지시데이터를 수신시 소재소건에 부합하는 라인속도, 전력비율, 강판온도, 강종, 강판두께, 도료메이커 및 도료종류에 따라 설정값을 테이블모델에서 자동으로 계산하고, 수동설정방법은 작업자가 입력/수정/편집할 수 있는 패턴테이블 형식의 작업표준을 제공하며, 또한 시뮬레이션 방법은 사용자 인터페이스 화면(HMI)에서 작업자가 소재조건을 변경하면서 PMT 값을 모사할 수 있는 기능을 부여함으로써 작업자가 NIR 작업을 위해 상기의 3가지 방식을 이용하여 설정값을 활용하도록 한 것을 특징으로 하는 연속칼라강판 생산에서의 근적외선을 이용한 건조작업 자동제어방법.
- 제 1항에 있어서, 상기 PMT값은 다음식으로 도출되는 연속칼라강판 생산라인에서의 근적외선을 이용한 건조작업 자동제어방법.PMT n =상수( const ) + a 1 P elec + a 2 v line + a 3 t sub + a 12 P elec v line + a 13 P elec t sub + a 23 v line t sub(*) PMT : 강판최고 건조온도(Peak Metal Temperature)n : 강종 (steel, AL, STS)const : 강판 색상에 따라 결정되는 상수ai : 강판 색상에 따라 각기 결정되는 계수pelec : 전력비율vline : 라인속도tsub : 강판두께
