Abstract

An offset conveyor system utilizes a lower conveying section positioned adjacent a pouring station where molten metal is poured into weighted and jacketed sand molds. Molds are transported on carriers along the lower section from a mold loading station to a weight and jacket placement station to the pouring station. After pouring, the carrier with jacketed mold is moved up an incline to an upper conveying section parallel the lower section and may overlap the lower section partially. Molds are transported in an opposite linear direction relative to the lower section to a weight and jacket removal station and to a mold dump station, where the sand mold and casting are removed from the conveyor. The carrier is returned to the lower conveyor section to receive another mold. The weight and jacket removed from the upper section is placed on a mold on the lower section, therefore only a minimum number of weights and jackets are used. The mold carriers may be dimensioned to carry sand molds in side by side relation thus, castings may circulate more than one circuit on the conveyor to permit additional cooling and solidification if necessary or multiple pourings may be accomplished.
