Abstract
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.
Claims8
A combination weighing apparatus comprising:
- a conveying unit that conveys an article;
- a plurality of hoppers that temporarily store the article conveyed by the conveying unit;
- a weighing unit that weighs a weighing value corresponding to the mass of the article stored in the hopper;
- and
- a control unit that executes combination weighing processing for selecting a weighing value combination, such that a total value becomes a target weighing value, from a plurality of the weighing values weighed by the weighing unit and associated respectively with the plurality of hoppers and controlling the hopper corresponding to the combination so as to discharge the article,
- wherein the control unit executes the combination weighing processing with a second value used as the 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.
