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

Article conveyance device and combination weighing device

In a combination weighing apparatus, a control unit executes combination weighing processing with a second value used as a target weighing value after controlling all of the hoppers so as to discharge the article while leaving the article in the conveying unit when the second value is less than a first value in a case where the target weighing value is changed from the first value to the second value.

Combination weighing device with control unit for targeted weight conveyance

Provided is a dispersion and supply apparatus and a combination weighing apparatus capable of uniformly supplying articles to a plurality of positions from a dispersion table. A dispersion and supply apparatusincludes an acquisition unitthat acquires a load amount of an article on a dispersion table, a calculation unitthat calculates a deviation in a loading state of the article based on the load amount acquired by the acquisition unit, and a control unitthat controls a driving unitsuch that a conveying direction of the article on the dispersion tableis changed based on the deviation in the loading state of the article calculated by the calculation unit

Dispersion and supply device and combination weighing device

A combination weighing apparatus includes a plurality of hoppers each having a gate and being capable of accommodating an article and discharging the article therefrom upon opening of the respective gate, a drive device for selectively opening and closing the gate and maintaining the gate in an opened position when in a conducting state, and a control device for controlling the drive device and having a weighing mode, in which the gates of the hoppers selected for combination are opened to combine the respective articles, and a discharge mode in which the articles within the hoppers are discharged while the gates are maintained in the opened position. The control device performs a control of closing the gate when during the discharge mode the opening of the gate lasts a predetermined length of time. The control device also performs a control of setting a closing duration of the gate during the discharge mode to a value longer than a closing duration of the gate during the weighing mode.

Combination weighing apparatus

An article handling system and method comprising a flow path along which articles travel and a metal detection system to detect the passage of metal items along the flow path. The system has a metal detector test system to support a metal test piece and positively move it along the flow path, and a metal detector to detect the metal test piece.

Article handling system

The weights of articles that are held in normal weighing hoppers are combined and a combination weighing takes places such that the total weight of the articles is within a predetermined weight range. When a combination weighing takes place and the articles that are held in the normal weighing hoppers are selected, special articles that are held in a special weighing hopper specified according to a specification routine are discharged. The present invention provides a general use combination weighing apparatus that is capable of changing the composition of combined articles discharged from the combination weighing apparatus according to predetermined conditions, without requiring a change in software and preferably without taking up a great deal of space.

COMBINATION WEIGHING APPARATUS WITH TWO DIFFERENT MODES, ONE MODE WHERE ALL HOPPERS ARE INVOLVED IN A COMBINATIONAL CALCULATION AND ANOTHER MODE WHERE COMBINATIONAL CALCULATION IS CARRIED OUT ONLY ON A FIRST GROUP OF WEIGHING HOPPERS AND WHERE A SECOND GROUP OF HOPPERS MAY BE DISCHARGED OR NOT BASED ON A WEIGHT INDEPENDENT CRITERIA

A combinational weighing system receives articles sequentially in a plurality of mutually parallel supply lines to be sequentially transported to weighing devices which are individually associated therewith and weigh batches of the articles received therefrom. Combinations of the measured weight values are combined and a particular combination of article batches is selected as having a total weight which satisfies a predefined condition. The article batches in the selected combination are transported in a general direction of flow from the weighing devices to an outlet in mutually different travel modes such that they are automatically aligned one behind another in the direction of flow as they are discharged together through the outlet.
