  • Patent number: 11912449
    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).
