To provide a small box arranging apparatus which can automatically arrange numerous small boxes into two or more stages of small box arrays neatly.

Small boxes 16 are respectively inserted from ahead into a lower part of a plurality of small box insertion spaces 28 formed on a horizontal plane in an arranged state via a plurality of vertical partitions 27 to form a small box array in a lower stage, while the horizontal plane is lowered and a plurality of small boxes 16 are respectively inserted into an upper part of each small box insertion space 28 to form a small box array on an upper stage. Then the small box array in the lower stage is raised to be in contact with a lower face of the small box array in the upper stage, while sides of the small box arrays in the upper and lower stages are brought into contact with each other, thereby integrating the small box arrays in the upper and lower stages.
