Abstract
PURPOSE: To automatically control the speed of a conveyor in high accuracy regardless of the variations of the slip by comparing the actual speed of the conveyor with standard speed set value and correcting the set speed signal used for the speed control closed loop of a drive motor.
CONSTITUTION: A variable motor 2 for driving a belt conveyor 1 via a reduction gear 3 is controlled by negative feedback signal en from tachometer generator (not shown) directly coupled with the motor 2 and the output E of an automatic controller 6 for receiving set speed signal es corredted. In order to obtain the speed signal es, it incorporates an oscillator 8, frequency divider 11, drive circuit 13, stepping motor 12, synchro control transformer 14, and phase comparator 19, and a speed setting potentiometer 7 for producing corrected DC signal ep substantially proportional to the rotation phase difference between the synchro oscillator 5 and the transformer 14, with an adder 21 for adding the output from the potentiometer 7 and the output of a speed setting potentiometer 20 controlled by a knob 9b.
