Abstract

PURPOSE: To maintain automatically the amount of an aggregate stored in a hot bin constant, by comparing the amount stored in the hot bin with a standard value, memorizing the deviation with the periodical sampling, and driving a cold feeder at the speed corresponding to the deviation.
CONSTITUTION: A detecting signal 30 from a detecting part 14 in a hot bin 9 is input to a continuous detecting circuit 17, and an output 31 therefrom is input to an indicating apparatus 18 and a deviation amplifier 19. The input data are compared with the preset value 32 of the optimum amount of storage in a standard setter 20 in the deviation amplifier 19, and the deviation output signal 33 is applied to a memory circuit 20. When a sampling signal 34 is applied from a synchronous circuit 21 to the memory circuit 20, the deviation output signal 33 at that time is memorized in the memory circuit 20. The signal 33 is applied to a controlled variable regulator 23 to drive a cold feeder 2 at a speed according to the deviation. The speed is maintained till the next deviation signal is sampled.
