PURPOSE: To enable a line to be operated smoothly even when respective processing times in a cast molding machine, a drying chamber and a glazing machine are different by returning one by one multiple pallets formed in piling up a number of pallets by means of a returning conveyor.
CONSTITUTION: A plurality of molding machines 2 serve to mount a molding obtained by flowing slurry into a cast mold onto a pallet P and forward one by one to a main conveyor C1 The molding is worked at a workmanship table 3 and dried in a drying chamber 5 for a night and day after giving a predetermined work by a processing machine 4 and glazed by a glazing machine 6. After glazing, the molding is separated from the pallet P and transferred to a baking process. On the other hand, when the pallet P unloaded is forwarded into pallet step-piling means 10, the means 10 is ascended by means of a cylinder 15 via a plane board 16 and then laminated on a recessed part 13a of an arm part 13 and further, after being piled to a predetermined number, ascended up to an imaginary line A'. Next, the multiple pallets P are pushed out to a returning conveyor 30 by means of a pusher 17. As the multiple pallets P is transferred to the entrance of the molding machine 2 by the returning conveyor 30, a pallet step destroying means 20 acts to forward pallets P to the main conveyor C1 sheet by sheet.
