Abstract
PURPOSE: To perform controlling of neutral positions of the vibrating table safely and surely by controlling the movements of the vibrating table by which hydraulic servo valves are feedback- controlled according to displacements, up to the neutral point of its excitation stroke by the gradually increasing target position signals.
CONSTITUTION: When a switch 25 is truned on, realy contacts x'a' xa are connected by way of a relay 23. Then, the control voltage corresponding to the vibrating table target neutral point having been set with a signal generator 17 is applied to the delay circuit 19 of a neutral control circuit 18 and an adder 21, the output whereof is then applied via adder 22 to an adder 4 to which the feedback signal by the displacement detection of the vibrating table servo controlling hydraulic valves via adder 22 is applied. On the other hand, as a timing relay 24 is energized by the specified time constant circuit corresponding to the time when the difference between the control voltage having been delayed by the circuit 19 and the control voltage becomes small, and realy contacts xb connect and the contacts xa space, as a result of which the control voltage having no delay of the circuit 17 is applied to the adder 4. Hence, the vibrating table is controlled by the gradually increasing control voltages and is thereby safely and surely moved to the target neutral point.
