Boxing apparatus

A boxing apparatus comprising:

• a pushing mechanism configured to push an article into a box having an opening facing sideways from a lateral side;
• and
• a posture changing mechanism configured to rotate the box by a first angle so as to change a posture of the box accommodating the article from a state where the opening faces sideways to a state where the opening faces upward,
• wherein the posture changing mechanism comprises:
• a suction unit configured to suction, from below, a suctioned side surface that is a side surface of the box located on a lower side of the box when the article is pushed in by the pushing mechanism;
• a support unit configured to support the suction unit;
• and
• a rotation unit configured to rotate the support unit by the first angle around a rotation axis parallel to a boundary line between the suctioned side surface and the opening,
• wherein the suction unit:
• starts suction in a state where the posture of the box is such that the opening faces sideways;
• and
• reduces a suction force or stops suction when the rotation unit rotates the support unit by a second angle that is less than the first angle, with reference to a time when the suction is started.
