However, the present invention is not limited to such a caser 1 or a method for assembling the cardboard box 3 using the caser 1.
For example, in the caser 1 and the method of assembling the cardboard box 3 using the caser 1 according to another embodiment of the present invention, a predetermined range of cuts may be made in advance at each corner in the upper opening of the cardboard box 3 in a semi-assembled state. Good.

Then, the height of the product 2A or 2B is measured by the sensor 6, and the first crease means 12 and the second crease are attached within the range of the cut depths of the inner flap 3c and the outer flap 3d according to the height. The folding position is determined by means 14. Then, the inner flap 3c and the outer flap 3d may be sequentially folded by the first folding means 17 and the second folding means 19.
In this case, if the length of the folding position is shorter than the cut depth, the cut is left at the corner of the side surface 3b of the corrugated cardboard box 3, but there is no problem in transportation and storage. Alternatively, the remaining cut may be sealed with the sealing tape 28 or an adhesive.

  In the above-described embodiment, the cardboard box 3 is used as a packaging box. However, the present invention is not limited to the cardboard box 3, and a box-like container using various papers can be used. In addition, the number of products 2 stored in the cardboard box 3 is arbitrary. In some cases, the height of the product 2 is set by stacking a plurality of products 2 in the upward direction, and the cutting length is determined. Good.
