Abstract: 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.

Abstract: 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.

Abstract: It is an object of the present invention to provide a weighing device in which dropping of articles from gripping means and reductions in weighing precision are suppressed. In a weighing device (100), when at least one of an operation state of grippers (30) and weighing results from weighing units (40) fulfills any condition from among “a weight value of articles (A) weighed by the weighing units (40) not being a preset target weight value,” “an operating distance in an operation in which the articles (A) are held by gripping members (32) being greater than a prescribed range,” and “the operating distance in the operation in which the articles (A) are held by the gripping members (32) being less than the prescribed range,” the articles (A) gripped by the grippers (30) are returned to an article group accommodation container (52) by a control unit (70) without said articles (A) being discharged to a discharge chute. As a result, a situation where the grippers (30) operate while still holding “articles for which the weight value is not the target weight value” is avoided.

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).
