A remedy judging system includes a weight checking device and a judgment unit. The weight checking device checks the weight of weighed product discharged from a weighing device. The judgment unit makes a judgment relating to remedies for the weighing device on the basis of 'correct weight,' “overweight,” and “underweight” checking results, relative to a predetermined weight serving as a norm, obtained by the weight checking device. The judgment unit makes the judgment on the basis of determination patterns having an “underweight” checking result and at least one checking result that consecutively follows the “underweight” checking result.

In an article processing apparatus (), a plurality of hoppers () are disposed in a circular shape and each of the plurality of hoppers () causes an article () received from an upstream side to temporarily stay and then discharges the article () toward a discharge opening () on a downstream side. Each of the hoppers () includes: a body portion (A); a slide portion (B) provided on a downstream side of the body portion (A), and having a slide surface () extending continuously from the body portion (A); and a gate (C) provided on the body portion (A) to switch between a first state where the gate (C) causes the article () to stay in the body portion (A) and a second state where the gate (C) releases the staying of the article () to cause the article () to slide down from the body portion (A). The slide portion (B) has a length (L) or an angle (A) with respect to a horizontal direction (H) of a path along which the article () slides down the slide surface (), takes off from a downstream end portion (E) of the slide portion (B), freely falls in a space (S) where the slide surface () does not exist, and then reaches the discharge opening (), in the second state.

Article processing apparatus

A combination weighing apparatus () according to one embodiment includes: a plurality of hoppers () to () that receives articles inputted from an outside, temporarily stores the articles, and discharges the stored articles downstream; a discharge chute () that receives the articles discharged from the hoppers and causes the articles to slide downstream; an acquisition unit () that acquires weight values of the articles stored in each hopper; and a control unit () that performs combination calculation on the basis of the weight values acquired by the acquisition unit and discharges the articles from a hopper determined by the combination calculation to the discharge chute. The discharge chute includes: a first slide surface () having a plurality of openings (A); and a second slide surface () that covers a part of the opening and is disposed at a position on an inner side of the discharge chute with respect to the first slide surface. The second slide surface is formed continuously with the first slide surface on an upstream side, a left side, and a right side of the opening.

Problem To improve the efficiency of a combination weighing operation. An article conveyance device 110 includes an article discharge container, an article conveyance mechanism, an article detection mechanism, and a control unit. The containerhas outletsto discharge articles A. The article conveyance mechanismhas feedersincluding a first feederto an n-th feederconfigured to convey the articles A. The article detection mechanismhas sensorsincluding a first sensorto an n-th sensorconfigured to detect the articles A in the first feederto the n-th feeder, respectively. The control unitjudges whether jamming of the articles A is occurring in the outletsbased on output of the article detection mechanism. The control unitincreases a conveyance intensity of some feeders receiving the articles A from places where the jamming is occurring in the outlets
