| To permit greater through-put of a mold box filling and compacting system, mold boxes are moved vertically by a lifting table which passes through the station transport turret (10) to place a pattern or mold carrier plate (11, 12) in the mold box, and, upon continued vertical movement, placing a filling frame (14) about the mold box, and, upon further vertical movement, placing the thus formed subassembly in engagement with a sand filling apparatus (15). Upon subsequent lowering, the subassembly is returned to the turret, the turret rotates and places the subassembly in position for alignment with a compacting station, raises the subassembly to the compacting station for compaction of the sand about the model or pattern. The subassembly is then lowered; after lowering for a short distance, the fill pattern transport, for example another turret or pivotable arm system, is placed in interfering position with the filling frame so that it is stripped off the mold box which is then lowered on a removal conveyor, for removal from the compacting station; continued downward movement at the compacting station table then places the now freed pattern or model carrier plate again on the station transport turret for return to the first position. Sand filling and compaction can be carried out simultaneously on sequentially arriving mold boxes under control of a control system (C) which controls appropriate sequencing. | ||||||
