In the conventional weighing method,
We use one weighing machine to get an accurate weighing value,
Therefore, when the articles that are continuously supplied are weighed as an article group and sequentially released to the next process, they must be released after the measured value of the supplied article group becomes stable, and the supply is stopped. However, there is a problem that it takes time to specify the weight value because it is necessary to wait for the goods that have already been supplied, but have not been added to the goods group and have not been added to the weight value, before weighing. there were. When the supplied article group reaches a preset weight value, the article group is discharged and the discharged and stored article group is weighed again to obtain an accurate weight value, and at the same time, the first weighing step. Then, it is intended to increase the weighing speed by using a coarse weighing value.

When the weighing value of the rough weighing signal a output from the weighing unit 4 reaches the set value, the drive stop signal b is output to the supply conveyor 1 which is conveyed in the direction of arrow A (step 22). The supply conveyor 1 is stopped. Here, even if the measured value reaches the set value, the measured value is not stable and swings around the set value. Further, even if the supply conveyor 1 is stopped, the confectionery 2 may be thrown in, or some may be thrown in before being stopped and not yet added to the measured value. Therefore, the measured value does not always indicate the accurate weight of the article group 5.
