Abstract:
[Problem to Be Solved] A pouring control method for controlling an automatic pouring device with a tilting-type ladle is provided. By the method, a lip of a pouring ladle approaches a sprue of a mold without striking any object located within the range of its movement. Also, by the method, the molten metal that runs out of the ladle can accurately fill the mold. [Solution] The pouring control method comprises the steps of setting a target flow rate of molten metal to be poured, generating a voltage to input it to a motor that tilts the ladle (hereafter, the tilting motor) so as to reach the target flow rate of the molten metal based on an inverse model of a mathematical model of molten metal that runs out of a pouring ladle and an inverse model of the tilting motor, estimating the flow rate of the molten metal that runs out of the ladle, estimating the falling position and getting the estimated falling position to be a target position, and generating a trajectory for the movement of the pouring ladle wherein the trajectory causes the height of the lip of the pouring ladle above the level of a sprue of a mold to decrease.
