Inter-container transfer device and inter-container transfer method

The turnover mechanism (3) turns over the first container (81) held by the holding mechanism in a state in which the first opening (81A) faces upward, and causes the first opening (81A) to face downward. The moving mechanism moves the holding mechanism such that a first opening (81A) facing the lower side faces a second opening (82A) from the upper side. The opening/closing drive mechanism (4m) causes the opening/closing body (4) to be in a closed state during the inversion of the holding mechanism by the inversion mechanism (3) and during the movement of the holding mechanism by the movement mechanism, and causes the opening/closing body (4) to be in an open state in a state in which the first opening (81A) and the second opening (82A) face each other. 翻转机构(3)使借助保持机构以第1开口部(81A)朝向上侧的状态保持的第1容器(81)翻转而使第1开口部(81A)朝向下侧。移动机构以朝向下侧的第1开口部(81A)相对于第2开口部(82A)从上侧相向的方式使保持机构移动。开闭驱动机构(4m)在借助翻转机构(3)进行的保持机构的翻转中及借助移动机构进行的保持机构的移动中使开闭体(4)呈封堵状态，在第1开口部(81A)与第2开口部(82A)相向的状态下使开闭体(4)呈开放状态。
