In other words, while utilizing the ceiling space, it is safely transported and put into the opening. Subsequent operations are substantially the same as those in the example of FIG.

In the example of FIG. 8, as in the example of FIG. 6, unnecessary products are removed from the cast product and then transferred using a charging machine, and transferred safely and by utilizing the space above the factory. . After the unnecessary product transferred by the charging machine is dropped into the bucket, the bucket is rocked and charged into the opening. Subsequent operations are almost the same as those in the example of FIG.

In the example of FIG. 9, as in the example of FIG. 6, unnecessary products are removed from the cast product, and then unnecessary contaminants and small-dimension unnecessary products are selected by using a conveyer. It is also possible to adopt the example of (1).) It is sequentially conveyed and put into the opening. Thereafter, the sheet is cut out and discharged out of the apparatus from the discharge port in substantially the same manner as in the example of FIG. 6, but in this example, after being transferred in two directions using the direction switching plate and the delivery conveyor, Is supplied to the furnace by using the conveyor.

In the example shown in FIG. 10, unnecessary products are removed from the cast product in the same manner as in the example shown in FIG. 6, and then the unnecessary contaminants and small-dimension unnecessary products are selected by using a feeding conveyor and an apron conveyor. While sequentially transporting it into the opening. Thereafter, the sheet is cut and ejected out of the apparatus from the ejection port in substantially the same manner as in the example of FIG. 6, but in this example, the sheet is sent to a transport bucket via an ejection chute and transported to a predetermined place. Then, it is supplied to a furnace.
