To provide a box separating feeding device to facilitate a work to separate and feed box bodies stacked in a plurality of stages and improve the efficiency of a work.

Through drive of a box shipping machine, a box shipping table 40 is elevated and stopped in a position in a level situated flush with that of a cardboard box B at each stage of the cardboard boxes stacked in a plurality of stages, and the cardboard box stacked at a topmost stage is held by a box press head 45 and horizontally moved in a shipping direction. The cardboard box B held by each box press head 45 is transferred to the box shipping table 40 once and a box shipping table is elevated and stopped in a height position situated flush with that of a conveyor 53 for shipping. The cardboard box B held by each box press head 45 is horizontally moved in a shipping direction and transferred to the conveyor 53 for shipping. Thereby, the moving distance and the operation time of the cardboard box B held by each box press head 45 are shortened and the efficiency of a work is improved. Further, low value of drive torque by which the press head 45 is horizontally moved will suffice for horizontal movement, and the size and the weight of the whole of a device are reduced.
