Development of High-Precision Automatic Pouring Machine Based on Process Analysis Supported by Control Engineering
The casting industry often uses a pouring process in which molten metal is poured into molds by tilting the ladle. Since molten metal is involved in the process, a dangerous environment for workers is created. Therefore, automatic pouring machines have recently been exploited to improve the working environment. These automatic pouring machines are required that molten metal is quickly and precisely poured into the molds, and are not spilled over the sprue cups. To realize a high speed and high precision automatic pouring machine, the pouring control system using Extended Kalman Filter which is one of nonlinear observer theories has been developed by the authors group. In this paper, the pouring control system is applied to the actual automatic pouring machine, and the experiments are done. The error ratio of poured liquid weight to the target weight is within 3％ in the case of pouring water, and within 5％ in the case of pouring actual molten metal without using the empirical knowledge and reducing speed.
