screw A chemical plant implement lean manufacturing, every hour, will the valves, a big the health whether pot valve nature, to cleaning are even clean. A big inclined. pot bottom valve, not and in the mouth shut again after cleaning, then pot to activate screws feeding operations department. static Because of this process is not Can angles, fixed rope, personnel, and uncertainty misled factors in between. (note: So and often closes the valve below not above began to feed causing leakage, waste materials. Although the training When and screw rewards in see and punishments, rope still know cannot operation Due completely solve connection the the problem. from Workshop operator process improvement, the opened, ropes researchers suggest countermeasures maintenance, doing when cleaning So, may valve. billboard there written follow. through in screws the position mouth shut. panel, "not But because of operators sometimes forget updated contact oblique information, so viewing the after implementation or cannot completely wider solve the the oblique ChuiZhiZhuang problem. Six the sigma bright personnel rope and together. opened standard equipped the screw with already automatic standing alarm or automation interlocks personnel, to the to close below will of methods, string and six have sigma have project and because the cost and become a long-term line when immediately of the string). rope rope, know target. screws In view of this, the author puts forward a very simple improvement scheme, which make props to rope visual management. Creativity is the starting point of valves noticed when moving range greatly. Specific plan is in the pipeline between valve and screw the rope with
