The article discharge system includes plural grippers, weight acquisition units, and a control unit. The grippers grip the articles. The weight acquisition units acquire weight values of the articles that each of the plural grippers grips. The control unit causes the plural grippers to grip the some articles from the article group disposed in the placement unit and, based on the result of a combination calculation using the weight values of the articles that each of the plural grippers grips, causes a predetermined combination of the grippers to release and discharge the articles. During the period after the control unit has caused the grippers to release the articles and before the control unit next causes the grippers to grip the articles, the control unit implements a zero correction process on the weight acquisition units corresponding to the grippers that were caused to release the articles.
