PURPOSE:To facilitate discrimination between the front and the back surfaces in a box preparation work as the posterior process by effectively correcting the warp of a corrugated cardboard sheet and piling-up said sheets in good order so that each inverted position can be immediately discriminated, by using a reversal piling apparatus for corrugated cardboard sheets. CONSTITUTION:A transfer conveyor 10 for a corrugated cardboard sheet laminated body 16 is constituted in the combination of a roller conveyor 12 and a belt conveyor 14, and the laminated bodies 16 which are cut in a prescribed dimension and piled-up in a constant warp angle are transported horizontally on the conveyor 10. A tilting apparatus 18 for tilting said laminated body 16 in a prescribed angle is arranged midway on the conveyor 10. With the tilting apparatus 18 in the tilted state, a corrugated cardboard sheet reversal feeding apparatus 38 is arranged at the top corner of the laminated body 16, and a corrugated cardboard sheet normal revolution feeding apparatus 40 is arranged at the position where the lower part of the top corner part is arranged. Further, an offset apparatus 68 for deflecting at right angles the corrugated cardboard sheet group which is fed only the time when said apparatus 40 operates, top edge arranging apparatus 76, and a lifter 78 are arranged. |
