PROBLEM TO BE SOLVED: To provide a seedling raising box stacking apparatus which performs stacking work appropriately and efficiently while preventing unevenness of soil or seeds in a seedling raising box.SOLUTION: A seedling raising box stacking apparatus sequentially supplies a seedling raising box C to a seedling raising box stacking position on a pallet P so that they are stacked. The seedling raising box stacking apparatus is provided with: a seedling raising box chuck 8b which picks up to hold the seedling raising box C at a seedling raising box pick-up position a robot arm 8a which moves the seedling raising box chuck 8b provided for a tip part between a seedling raising box pick-up position and the seedling raising box stacking position and a turning mechanism 97 which turns the seedling raising box chuck 8b with respect to the robot arm 8a about an axis in a vertical direction. The apparatus is configured to move the seedling raising box C from the seedling raising box pick-up position to the seedling raising box stacking position while turning the seedling raising box C by the action of the robot arm 8a and the turning mechanism 97.COPYRIGHT: (C)2016,JPO&INPIT
