PROBLEM TO BE SOLVED: To solve the problems of heavy labor because the conveyance of seedling containers in small-scale seedling-raising operation is carried out manually.SOLUTION: There is provided a method for piling up seedling containers, comprising holding the first seedling container A at a supporting position by a left receiving frame 22 and a right receiving frame 23 for lifting and lowering the seedling container A, lowering the left receiving frame 22 and the right receiving frame 23 in combination with the seeded first seedling container A when a following second seedling container A is received at the lower side of the first seedling container A to pile up the first seeded seedling container A on the second seeded seedling container A, repeating the piling up steps, and when the seedling containers A at the number fewer than a prescribed number by one are received, piling up the already piled up seedling containers A on the seedling containers A at the number fewer than a prescribed number by one to afford the seedling containers at the prescribed number, sending out the piled up seedling containers A to the front side of a transfer table frame 4, and starting and repeating the piling up steps from the beginning.COPYRIGHT: (C)2014,JPO&INPIT【課題】小規模育苗作業における育苗容器の搬送が人手による手作業で行うため、重労働であるという課題がある。【解決手段】育苗容器Aを昇降させる左受枠22および右受枠23により支持位置にて一枚目育苗容器Aを保持し、一枚目育苗容器Aの下方に後続二枚目育苗容器Aを受け入れると、左受枠22と右受枠23を播種済みの一枚目育苗容器Aと共に下降させて、播種済みの二枚目育苗容器A上に播種済みの一枚目育苗容器Aを重ね、この積み上げ行程を反復し、所定枚数から一枚少ない育苗容器Aを受け入れると、所定枚数から一枚少ない育苗容器A上に既に積み上げた育苗容器Aを重ねて、所定枚数の育苗容器Aとすると、段重ね育苗容器Aを移送台フレーム4の前方に送り出し、前記積み上げ行程を最初から開始して反復する育苗容器重ね方法。【選択図】図16
