PURPOSE:To prevent a blending agent from being excessive or deficient and to eliminate errors in blending and grouping by scaling a blending agent by using the judging function of the scaling device of a scaling carriage and opening a blending agent throw-in door by a controller according to the kind of the scaled blending agent. CONSTITUTION:The scaling device 71 has a scaled value display part 72 and a scaled value judging function and scales a blending agent which is supplied to a small-amount-feed container on a first-out basis when the blending agent supply door of the blending agent supply unit is opened. Blending agent throw-in containers 91, 92, and 93 are so provided that the blending agent which is scaled by a scaling machine 71 is thrown in by groups in blending order. Blending agent throw-in doors 75, 76 and 77 are provided to the containers 91, 92, and 93 and those doors are opened and closed under the controller of a controller composed of a microcomputer according to the kind of the scaled blending agent. Said scaling device 71, containers 91, 92, and 93, doors 75, 76, and 77, etc., are mounted on the scaling carriage which has a housing 87 and connected to the controller through a power cable and an optical communication cable to perform scaling operation.
