<p>An offset conveyor system (10) utilizes a lower conveying section (11) positioned adjacent a pouring station (61) where molten metal is poured into weighted and jacketed sand molds. Molds (21) are transported on carriers (16) along the lower section (11) from a mold loading station (31) to a weight and jacket placement station (41) to the pouring station (61). After pouring, the carrier (16) with jacketed mold (21) is moved up an incline to an upper conveying section (13) parallel the lower section (11) and may overlap the lower section (11) partially. Molds (21) are transported in an opposite linear direction relative to the lower section (11) to the weight and jacket removal station (41) and to a mold dump station, where the sand mold (21) and casting are removed from the conveyor (13). The carrier is returned to the lower conveyor section (11) to receive another mold. The weight and jacket (22) removed from the upper section (13) is placed on a mold (21) on the lower section (11), therefore only a minimum number of weights and jackets (22) are used. The mold carriers (16) may be dimensioned to carry sand molds (21) in side by side relation thus, castings may circulate more than one circuit on the upper and lower conveyors (11, 13) to permit additional cooling and solidification if necessary or multiple pourings may be accomplished.</p> |
