PURPOSE: To continuously take out the content of a corrugated cardboard box, by a method wherein the corrugated cardboard box whose side surface on the bottom side of content is cut off is placed on an L-shaped rotary box receiving plate in such a state that the content thereof is received sideways and the rotary box receiving plate is rotated by 90° to leave the content on the rotary box receiving plate in an erected state and the content is transferred to a feed conveyor.

CONSTITUTION: A corrugated cardboard box 2 is placed so that the contents 1 thereof turn sideways and rotary blades 3 are moved along the entire periphery of both ends of the corrugated cardboard box 1 to cut off the side surface 4 becoming the bottom side of the contents of the corrugated cardboard box 1. Subsequently, the opened corrugated cardboard box 2 is placed on a conveyor 5 in such a state that the contents are received in said box and fed to be transferred to an L-shaped rotary box receiving plate 6. Next, when the rotary box receiving plate 6 is rotated by 90°, the contents 1 are brought into contact with the horizontal surface of the receiving plate 6 to be erected. When an outside cylindrical corrugated cardboard box 2 is raised in this state by a grasping pawl 7, only many contents are erected on the receiving plate 6. Press plates 8 are respectively applied to the front and rear of the contents 1 erected on the rotary box receiving plate 6 to move the contents 1 to a conveyor 9 and, thereafter, the press plates 8 are retracted to feed the contents 1 by the conveyor 9.
