In accordance with the rotation operation of the front and rear conveying shaft 24 and the left and right conveying shaft 40, the moving body 56 provided at both ends of the front and rear conveying shaft 24 and the left and right conveying shaft 40 is moved to the box B side. .

As the movable body 56 is moved to the box B side, the pressing plate 70 of the clamp member 60 connected to the movable body 56 is pressed against the box B, and thus, before the box B, After, the left and right sides are gripped.

When the gripping operation of the box B of the clamp assembly 10 is completed, the rotation frame 4 of the loading apparatus 2 is rotated to the pallet P side, and is opposite to the gripping operation of the clamp assembly 10. The clamp assembly 10 is operated in sequence, and the gripping operation of the box B is performed.

By repeating the above series of operations, the box B is automatically loaded in multiple stages on the upper surface of the pallet P as shown in FIG.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.
