Goods drop out method

A method of dropping out goods, in which goods are stored in a plurality of goods receptacle portions defined by partitioning walls inserted into a drop-out box defined at least by side walls, and an opening and closing device provided on bottoms of the goods receptacle portions are operated to open to enable dropping out of the goods from respective goods receptacle portions, the method comprising the steps of:

• selecting insertion positions of said partitioning walls in said drop-out box to selectively modify an arrangement pattern of said goods receptacle portions in said drop-out box;
• providing said opening and closing device with a plurality of smaller opening and closing members corresponding to a minimum interval of said partitioning walls to be inserted into said drop out box in parallel relationship to each other;
• determining the insertion position of the partitioning walls in said drop-out box such that in at least one selected arrangement a single one of the smaller opening and closing members corresponds to the bottoms of both of adjacent goods receptacle portions defined in said arrangement pattern;
• and
• operating all of said smaller opening and closing members at least partly corresponding to the bottom of respective goods receptacle portions upon dropping out of the goods from the respective goods receptacle portions.
