Abstract
A cooling conveyor control system which selectively controls a mold cooling conveyor assembly adapted to receive poured molds from the pouring rails of an automatic molding machine and transport them to a collecting conveyor or shakeout mechanism in a continuous or selectively spaced apart mold string. A cooling conveyor control system is provided whereby the cooling conveyor is indexed to move synchronously in response to corresponding operation of the molding machine. The control system includes an electronic controller which processes information received from the control system of the molding machine with feedback information from the hydrostatic drive of the cooling conveyor so as to produce a signal which operates a servo valve to correspondingly control the drive system of the cooling conveyor assembly. The electronic controller acts in response to signals from the control system of the molding machine so as to index the cooling conveyor forward at the precise acceleration, deceleration, and pitch required to maintain a continuous mold string from the molding machine to the collecting conveyor or shakeout.
