た。 Some of the above-mentioned sorting devices dynamically weigh the articles to be sorted by using a weighing conveyor as a weighing device that weighs the articles to be sorted while conveying them.
That is, the deviation between the dynamic weighing value and the standard weight is calculated, and this deviation is compared with the allowable deviation (Japanese Patent Application Laid-open No. 116179/1983). Since such sorting equipment uses a weighing conveyor, the dynamic weighing value of the sorted articles may vary due to disturbances such as impact loads caused by the shape of the sorted articles and the conveyance speed. The value will be different from the static measurement value measured in a stationary state. On the other hand, standard weight uses static measurement values. Therefore, since the dynamic weighing value and the standard weight of the articles to be sorted are based on different states, errors are likely to occur in the sorting results. Therefore, a correction device was added and operated by a worker to correct the dynamic weight value to the static weight value to prevent missorting, but it took a long time to operate, and It was not possible to make accurate corrections.
この発明は、簡単な操作だけで正確に誤選別を
防止できる選別機を提供することを目的とする。 An object of the present invention is to provide a sorting machine that can accurately prevent erroneous sorting with only simple operations.

Assume that the stop/start switch 40 is now switched to the stop side to stop the weighing conveyor, and the correction/weighing mode switch 38 is switched to the correction mode side. In this state, switch the start/stop switch 40 to the start side,
The weighing conveyor is started, and the articles to be sorted whose static weight value is equal to the standard weight are conveyed n times on the weighing conveyor. As a result, the integrating circuit 46 stores n dynamic measurement values, and the count value of the counting circuit 48 becomes n. When the M2 key is pressed at this time, the divider 50 divides the output of the integrating circuit 46 by the output of the counting circuit 48, and calculates the average value of the dynamic weight values. This average value is stored in the storage unit 32 as a standard weight.

The arithmetic control section 30 stores the digital dynamic measurement value from the A/D conversion circuit 36 and the storage section 3.
The deviation from the standard weight (average value of dynamic weighing values) stored in 2 is calculated, and this deviation is compared with the allowable upper limit deviation and allowable lower limit deviation stored in the storage unit 32 to determine whether the amount is excessive or not. Or select it as lightweight.

This center value is determined by storing n dynamic weight values obtained by weighing articles to be sorted whose static weight values are equal to the standard weight n times on a weighing conveyor, and using the arithmetic circuit 56 to store these n dynamic weight values. The maximum value among the dynamic metric values is determined and removed, the minimum value is determined and removed from the remaining (n-1) dynamic metric values, and this process is repeated to obtain (n-1).

It may be configured such that this is carried out by switching the correction/weighing mode changeover switch 38 to the weighing mode side after the number of times of conveyance. In addition, in the above embodiment, in order to improve the accuracy of correction of the standard weight to the dynamic weighing value, a plurality of articles whose static weighing value is equal to the standard weight are conveyed an arbitrary number of times on the weighing conveyor. The average value or center value of the dynamic weight values was used as the dynamic weight value for the standard weight, but the dynamic weight value obtained by conveying the above items on the weighing conveyor only once was used as the dynamic weight value for the standard weight. It may also be used as
