Abstract
A control system operates an automatic ladling apparatus for conveying molten metal from a furnace to a die casting machine or the like. The control system includes a plurality of adjustable speed control settings so that the speed of the apparatus can be varied according to operating conditions. The rate at which molten metal is poured into the die casting machine may also be varied. The position of the apparatus is monitored so that speed is automatically varied according to the position, and these positions are programmable. The control system includes an abort sequence to pour molten metal back into the furnace automatically if the die casting machine is not ready to accept the pour.

- means for moving the ladle transport assembly from the metal reservoir to the casting apparatus at varying speeds;
- means for tilting the ladle dipper at varying speeds when the ladle transport assembly is at the casting apparatus to pour molten metal into the casting apparatus;
- adjustable means for setting a plurality of individual speeds;
- means for selecting one of the plurality of speeds;
- means for supplying the selected speed from the selecting means to the moving and the tilting means;
- means for controlling the selecting means in response to predetermined inputs.
