An article discharge system includes a placement unit in which the article group is placed, plural grippers, a movable member, a robot that moves the movable member, weight acquisition units, and a control unit. The plural grippers grip some articles with gripping member. The plural grippers are attached to the movable member. The weight acquisition units acquire weight values of the articles that each of the grippers grips. The control unit moves the movable member, brings the plural grippers closer to the placement unit, causes the plural grippers to grip some of the articles of the article group placed in the placement unit, and, based on the result of a combination calculation using the weight values of the articles that each of the grippers grips and which the weight acquisition units have acquired, causes predetermined grippers among the plural grippers to release the articles and thereby discharge the articles.

Article discharge system

An article gripping device causes a gripping member to grip an article, and subsequently discharge the article by releasing the gripping of the article by the gripping member. The article gripping device is provided with a gripping member driving mechanism to drive the gripping member, and a controller to control the gripping member driving mechanism. The controller has, as control modes for the gripping member driving mechanism, a first control mode and a second control mode that is separate from the first control mode. In the first control mode, the controller controls the gripping member driving mechanism to cause the gripping member to execute a first operation of gripping the article and subsequently releasing the gripping of the article. In the second control mode, the controller controls the gripping member driving mechanism to cause the gripping member to execute a second operation of removing matter adhering to the gripping member.
