Abstract: Provided is a highly reliable box-opening device being capable of suppressing failures of a box-opening action regardless of a size of a cardboard box sheet. The box-opening device unfolds a sheet in which first and second side surfaces and third and fourth side surfaces overlap, and forms a square-tube-shaped cardboard box. The box-opening device may have a suction disk to grasp the first side surface, a main arm having suction disks to grasp the fourth side surface and changing a posture while grasping the fourth side surface, and a control part to control a movement of the main arm so that an initial action, in which a gap is formed between the first and second side surfaces and the third and fourth side surfaces, and a main action that follows the initial action, are executed as an action of unfolding the sheet.

Abstract: To provide an article gripping system that reduces the installation area of the apparatus and further shortens the amount of time from when it grips to when it feeds articles. An article gripping system (110) switches between a first positional relationship in which a container (50) obstructs discharge of articles gripped by a first gripping unit (15A) but does not obstruct discharge of articles by a second gripping unit (15B) and a second positional relationship in which the container (50) obstructs discharge of articles gripped by the second gripping unit (15B) but does not obstruct discharge of articles gripped by the first gripping unit (15A), so the gripping units do not move while they are holding the articles, and the articles can be prevented from falling out of the gripping units (15).
