PROBLEM TO BE SOLVED: To provide a stacking facility which improves working efficiency, while maintaining a stacking attitude of seeding raising boxes and thereby maintaining transferring accuracy excellently.SOLUTION: A stacking facility includes: a stacking device (117) for stacking a prescribed number of seeding raising boxes (C) carried by a seeding raising box-carrying conveyor (103) by lifting the seeding raising boxes from below a loading device (118) for holding the seeding raising boxes (C) stacked by the stacking device (117), horizontally transferring the seeding raising boxes, and then loading a prescribed number of seeding raising boxes a loading arm (119) for placing the seeding raising boxes (C) loaded by the loading device (118) and a transfer mechanism (120) for transferring the loading arm (119) vertically and horizontally to a prescribed position. The loading device (118) includes a movable arm (126) that moves in a lateral direction to hold the seeding raising boxes (C). The movable arm (126) is configured to be adjustable by moving back and forth.COPYRIGHT: (C)2015,JPO&INPIT【課題】 本発明は、段積設備において、育苗箱の積付姿勢ひいては移載精度を良好に維持しながら、作業能率向上を図ることを課題とする。【解決手段】 育苗箱搬送コンベヤ(103)で搬送される育苗箱(C)を下方から持ち上げて所定の段積枚数に段積する段積装置(117)と、該段積装置(117)で段積された育苗箱(C)を把持して横移動し所定の積付枚数に積付ける積付装置(118)と、該積付装置(118)で積付けられた育苗箱(C)を載せる積付アーム(119)と、該積付アーム(119)を上下移動及び横移動させて所定位置に移載する移載機構(120)を設け、積付装置(118)には、横方向に可動して育苗箱(C)を把持する可動アーム(126)を設け、可動アーム(126)を前後に移動調節可能な構成とした段積設備とした。【選択図】 図4
