などに集合される。The control unit 6 receives the weighing values from each of the weighing instruments 5-1 to 5-n, and records data other than the weight of the weighing hopper, such as the weight of the weighing hopper itself.
The flea value (zero point correction value) is subtracted from the measured value, and based on this π point corrected measurement value, each storage chamber 3-1 to 3-n,
The weight values of the objects to be weighed stored in 4-s to 4-n are displayed, respectively. Then, based on each weight value or the individual @ value of the object to be weighed (q) from this weight value, combination calculations are performed on all different combinations, and the optimal combination for the set amount is selected. The objects to be weighed in each storage space of the selected combination are discharged and collected into the collecting chute 7.
etc. are collected.

となる。Therefore, in the zero point correction of the above-mentioned weighing device, the total value of the empty weighing hopper weight measured at the time of starting the weighing device is the first value of 11' as the zero point correction value! However, during the operation of the meter, the zero point correction value may be changed from time to time due to drift of the meter due to temperature, etc., or debris from the weighing object adhering to the weighing hopper. will need to be reconfigured.

値の再設定を行なうようにしていた。For this reason, conventionally, when eight wave gauges in all storage chambers of the weighing hopper corresponding to the measuring instrument whose new zero point correction value is to be reset are simultaneously selected and discharged, the zero point correction value is changed. I was trying to reconfigure it.

出はおこらない。<Problems to be Solved by the Present Invention> However, the probability that objects to be weighed in all storage chambers of a weighing hopper will be combined and selected at the same time is low (for example, in the case of a plurality of weighing hoppers each having two storage chambers) In this case, the probability of obtaining a combination including the objects to be weighed in both chambers of any one of the counting hoppers is approximately 1/4 degree). therefore,
Even if it is determined which scale is to be used to re-determine the zero point correction value, simultaneous ejection of the 1n workpieces will not occur until several combined ejection operations have been performed.
このため、零点補正値の再設定効率が非常【こ悪いとい
