Abstract
A combinational measuring device is provided with a radiation feeder transporting objects and a measuring hopper measuring the weight of each group of objects transported by the radiation feeder. As to each measuring hopper performing introduction by a prescribed frequency, an average operation part obtains an average and standard deviation of a transport quantity every group transported by the radiation feeder. On the basis of the obtained standard deviation, a parameter operation part determines whether or not the transport quantity per group transported by the radiation feeder is dispersed. The parameter operation part operates a control parameter so that the transport quantity per group transported by the radiation feeder reaches a target introduction value if the transport quantity per group transported by the radiation feeder is stable, while operating the control parameter so that the transport quantity per group transported by the radiation feeder is not in excess of a target measured value if the transport quantity per group transported by the radiation feeder is dispersed. The combinational measuring device controls driving of the radiation feeder on the basis of the obtained control parameter. Thus, it is possible to provide a combinational measuring device performing efficient measurement.
