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.

Abstract: A combinational weighing device is provided with a detection part detecting a measuring state on the basis of the quantity of a object introduced into each measuring hopper and a correction part operating a target dispersed weight defining the reference for control on a cross feeder by a supply control part. The correction part corrects the target dispersed weight in response to the measuring state of the combinational weighing device detected by the detection part. In other words, the correction part controls the quantity of the object supplied to a dispersion feeder on the basis of measured data indicating an actually measured value. Thus provided is a combinational weighing device performing efficient measurement without complicating the device structure.
