Abstract
An opening arm has a thickness smaller than a clearance between a pair of flaps that are formed adjacent to each other in one plate-like portion of a pair of plate-like portions of a cardboard sheet folded like a plate. The pair of plate-like portions face each other. A moving portion moves the opening arm. In a state where the opening arm is inserted in the clearance G1 between the pair of flaps, the opening arm faces a flap that is formed in another plate-like portion of the pair of plate-like portions and that is located at a position that faces the clearance. The moving portion moves the opening arm such that the opening arm pushes the flap formed in the other plate-like portion, and that the other plate-like portion is separated from the one plate-like portion.
Claims8
A box forming apparatus configured to form a cardboard sheet into a box with a substantially rectangular shape when viewed from above, the cardboard sheet including four continuous faces and a plurality of flaps, the plurality of flaps including a first flap, a second flap, a third flap, and a fourth flap each extending from an upper end of a corresponding one of the four faces and the plurality of flaps including a fifth flap, a sixth flap, a seventh flap, and an eighth flap each extending from a lower end of a corresponding one of the four faces, the cardboard sheet being formed into a box by opening the four faces of the cardboard sheet and by folding the fifth to eighth flaps of the cardboard sheet, the box forming apparatus comprising:
- a first pressing unit configured to press the first flap through a first gap between the second flap and the third flap, the second flap being adjacent to the third flap;
- a second pressing unit configured to press the third flap through a second gap between the first flap and the fourth flap, the fourth flap being adjacent to the first flap;
- a moving unit configured to move the first pressing unit and the second pressing unit relative to each other and open the four continuous faces of the cardboard sheet;
- and
- a folding unit configured to fold the fifth to eighth flaps of the cardboard sheet relative to the four continuous faces of the cardboard sheet.
