PURPOSE:To permit the bagging of two kinds having different weights with one device in the case of such bagging and to reduce the size of the device by changing alternately preliminarily determined weights in the respective combination calculations to be repeated. CONSTITUTION:A subtractor 30 calculates the deviation of the successively supplied combination addition values with respect to a set weight and a discrimi nating part 32 selects the combination equal to the lower limitor most approxi mate thereto and stores the same into a combination storage device 34. A timer 36 generates an output when the generation of all the combination signals ends. A discharge control part 16 opens the discharge gate of the selected measuring tank out of said tanks according to the storage value of the device 34. A charg ing control part 8 supplies the signal to an OR gate 29 and a start signal is supplied to a change-over part 38, by which change-over switches 40, 42, 44 are changed over. The set weight, upper limit deviation and lower limit devia tion are therefore alternately changed over from the 1st to the 2nd ones and from the 2nd to the 1st ones at every generation of the start signal form the OR gate 29.
