PURPOSE: To provide a proper amount of mixture at a proper ratio by cumulatively monitoring the weights of a receptacle and a liquid, controlling solenoid valves and the like, and charging the receptacle with a predetermined amount of liquid from a plurality of delivery sources.

CONSTITUTION: This control system has disposed therein a plurality of delivery heads 10-30 and a plurality of delivery sources 120-140, and a plurality of liquid containers 12-32, a plurality of liquid pumps 14-34, and a plurality of solenoid valves 11-31 are attached to the delivery sources 120-140. A receptacle 43, a weight-sensing device 9 and the like are attached to a delivery station 40. The weight-sensing device 9 is connected to a control computer 50, which is in turn connected to the solenoid valves 11, 21, 31. The weights of the receptacle 43 and a liquid are cumulatively monitored to charge the receptacle 43 with a predetermined amount of liquid from each of the delivery sources 120, 130, 140. Thus, a mixture can be obtained in a proper amount at a proper ratio.
