Abstract: A goods arrangement system includes a goods storage arrangement apparatus 7000 capable of storing goods temporarily and discharging a specified number of goods at the same time. The goods storage arrangement apparatus 7000 consists of a gradient storage shelf 7774 made up of multiple gravity roller conveyors 7001, and arrangement conveyors 7002 associated with the stories of gravity roller conveyors. Unpackers 1000 and 2000 peel off outer flaps from each box (container) containing goods, and a flap opener 4000 opens up and down outer flaps on one of the sides of a box. A goods takeout apparatus 5000 takes out goods from a box. The taken-out goods are fed to the goods storage arrangement apparatus 7000 by a goods feeder 6000 based on a running cart 6034. In the goods storage arrangement apparatus 7000, the arrangement conveyors 6002 arrange multiple goods in a row substantially perpendicularly to the direction in which the arrangement conveyors run.
