PURPOSE: To prevent the occurrence of collapse of a load stack at accumulation time by scheduling work order of raw materials so as to gradually become a pyramid shape when product groups created with every raw material are accumulated.
CONSTITUTION: A work order indicating means 12 beforehand calculates an arranging range of product groups 5 obtained from respective raw materials 3, and ranks order of the respective raw materials 3 according to a calculated value in the arranging range, and compares dimensions with each other with every order-ranked raw material 3, and detects the raw materials 3 not more than a prescribed rate and ratio, and prevents the occurrence of collapse of a load stack at piling-up time of a raw material pileup 2. Next, a raw material accumulation indicating means 13 creates the raw material pileup 2 in ranked order, and carries the raw materials 3 to a work means 4A from this raw material pileup 2 according to the order, and performs prescribed work. Next, a product pileup indicating means 14 raises the product groups 5 worked from the raw materials 3, and arranges either end part, and piles it up as a product pileup 7.
