PURPOSE:To turn an object upside down in the air by wrapping it with an endless belt regardless of its shape, strength, and weight, by wrapping an endless belt around plural rotary bodies, and making one or more of the rotary bodies movable, and providing a driving means for traveling the belt. CONSTITUTION:A core box 1 is transferred by a roll conveyor 6, and is moved to the central part of a pair of rolls 4 by a conveyor belt 2 driven by the rolls 4. Next, when a platen 7 for inverting is put on the box 1 and rolls 5 are moved upward, the belt 2 is slackened to lower the box 1. Next, when the rolls 4 are moved in the mutually closing direction to wrap the box 1 with the belt 2, the roll 4 rotates to drive the belt 2 in the right-headed rotation direction, and the box 1 is turned upside down in the left-headed rotation. Then the rolls 4 are moved in the mutually separating direction, and the rolls 5 are moved downward to tighten the belt 2, and the box 1 is moved upward; then the inverted box 1 is transferred onto a roll conveyor 6 located at the right side. |
