The combination weighing device according to the present invention,
Performs a combination operation based on the number value of the articles in each hopper obtained by dividing the weight of the articles weighed by the weighing hopper by the unit weight of the articles, and the combined addition value is the set number or a value close to it. It includes a device for selecting the optimum combination and discharging and collecting the articles only from the selected hopper.

As described above, according to the present invention, each of a plurality of weighing hoppers having a weighing machine is provided with a reservoir hopper, and articles supplied to both the weighing hopper and the reservoir hopper. Since a combination calculation is performed based on the measured values of, and the optimum combination whose combined addition value is equal to or close to the set value is selected, a large number of measured values can be obtained with a small number of weighing machines. As a result, the weighing accuracy can be improved without complicating or increasing the size of the structure of the combination weighing device.

Further, according to the present invention, when the weighing hoppers corresponding to the upper and lower sides and the storage hoppers simultaneously correspond to the optimum combination by the combination calculation and the articles in both hoppers are discharged, the next weighing is performed. Since the combination calculation is performed immediately in the state where the articles are supplied only to the weighing hopper, in such a case, waiting for the combination calculation after waiting for the articles to be supplied to both the weighing hopper and the storage hopper is performed. An increase in time is avoided, which in turn prevents a reduction in the throughput of the metering device.

According to the present invention, in particular, when the articles are discharged from both the vertically corresponding weighing hopper and the storage hopper as described above, the articles are discharged to all the hoppers at the next next weighing. Since it is supplied, there is an advantage that the combination calculation is performed only once in the state where the measured value is missing.

1. A combination calculation is performed based on the measured values of the articles supplied to each of a plurality of hoppers, and an optimum combination having a combined addition value equal to or close to a set value is selected, and the optimum combination is selected. In a combination weighing device configured to discharge and collect only the articles in the hopper corresponding to the above, a plurality of weighing hoppers having a weighing machine and two systems of discharge ports are provided as hoppers that participate in the combination calculation. , A plurality of reservoir hoppers each having a single discharge port and disposed below one discharge port of each of the weighing hoppers and to which weighed articles are supplied from an upper weighing hopper, and the combination described above. When the weighing hoppers corresponding to the upper and lower sides and the storage hoppers correspond to the optimum combination at the same time and the articles in both hoppers are discharged by the calculation, these hoppers will be used for the next weighing. Then, while supplying the goods only to the weighing hopper, the weighing values are not allowed to participate in the combination calculation,
By the article supply operation at the time of the next weighing, the articles in the weighing hopper are supplied to the storage hopper, and the articles are newly supplied to the weighing hopper. At this point, the weighing values of the articles in both hoppers are combined and calculated. A combination weighing device comprising arithmetic control means for participation.
