Abstract: A case sealing device is disclosed. The case sealing device conveys a cardboard box and simultaneously closes a flap group provided on edges of opening of the cardboard box. The case sealing device includes a folding member, a drive unit, and a control unit. The folding member contacts a flap of the flap group that extends along a conveyance direction of the cardboard box and folds the flap. The drive unit moves the folding member. The control unit controls the drive unit. In operation of folding the flap, a longitudinal direction of the folding member is inclined with respect to the conveyance direction such that the folding member contacts a front edge of the flap in the conveyance direction before other portions of the flap.

Abstract: A cardboard box assembly device, that folds four flaps provided at edges of an opening in a cardboard box to surround the opening, is disclosed. The cardboard box assembly device includes a folding unit, a pushing unit, and a drive unit. The folding unit folds each of the four flaps in a prescribed sequence and closes the opening. The pushing unit pushes one of the four flaps, that is folded last, inward into the cardboard box as a locking flap, and overlaps the locking flap onto the other flaps. The drive unit contacts the cardboard box and imparts a prescribed displacement to the cardboard box. Parts that engage with one another are formed between the locking flap and at least one of the other flaps. The drive unit moves the locking flap relative to the other flaps due to the displacement when the pushing unit pushes the locking flap.

Abstract: A lid forming device of a cardboard box using a first flap with a slit and a second flap to be extended after being bent into a mountain shape is disclosed. The lid forming device includes first and second folding mechanisms. The fist folding mechanism folds the first flap in a direction of closing the opening. The second folding mechanism bends the second flap into a mountain shape and inserts part of the second flap into the slit of the first flap while extending the second flap. The second folding mechanism includes first and second retaining units. The first retaining unit retains a first face of the second flap located between a free end of the second flap and a bend line set beforehand in the second flap. The second retaining unit retains a second face of the second flap located between an anchored end and the bend line.
