Colored portions, such as a blue portion 14, a green portion 15, and a red portion 16, which are color-coded by a paint, a color tape, or the like, are provided. The coloring portion is used as a mark when arranging one or a plurality of articles on the placement surface, and the coloring area is determined by the size of the article to be placed and the number of placements per stage. For example, when a plurality of articles having a bottom surface of 200 mm × 200 mm are placed on a mounting surface of 900 mm × 900 mm, the blue part 14 is 450 mm × 450 mm and the green part 1 is
5 is 650 mm x 650 mm, red part 16 is 850 mm
× 850 mm, coloring is performed based on the center of the pallet at each mounting area. In this case, each colored portion is slightly larger than the mounting area of the article.

The operator determines the number of articles to be placed per one stage based on the type and weight of the article. If the number is four, the blue part is 14; if the number is nine, the green part is 15; Then, each color is placed from the end to the center. At this time, the worker places the article with the colored part of the mark slightly protruding from the article, and can always recognize the appropriate arrangement state based on the protruding color and amount. It can be performed. In addition, by accurately placing the first stage, it is possible to prevent collapse of the load even when the stages are placed in multiple stages.

The interval between the colors (200 in the above embodiment)
