METHOD FOR OPERATING ROTARY PROJECTING SIGNBOARD CAPABLE OF GOING FORWARD AND BACKWARD AFTER ONE REVOLUTION ACCORDING TO ELECTRONIC CIRCUIT

摘要

The present invention has been built yet another protrusion protruding inside the sign sign frame to rotate, on the way to be operated by an electronic circuit; And more particularly, to the another projecting sign of the internal projecting signboard rotating in one rotation hanhu rotation protrusion signboard frame advance comes in the rotation projecting sign frame, and when optionally a time setting again the rotation projecting signboard departs in the framework It relates to a method of operation by entering the electronic circuit.; To this end, the present invention senses the first rotational position of the rotating protrusion rotates signboard 1 executes a procedure according to the design of electronic circuitry to access the sensor and cuts off power to the motor rotation speed reduction.; And at the same time the electromagnetic brake is fixed to the rotation geared motor and the end of the set time of the second timer times of starting the stop position of the minute projection sign again out comes to a projecting signboard it is advanced embedded in rotation protrusion signboard frame proximity sensor is detected, and the end of the If the second timer time is started early time time cuts off power to the geared motor to reverse and re-decelerating the motor operation enters into the rotary projecting sign frame and the reaches the predetermined position approaches the sensor detects the geared motor Disconnect the power supply. And once again, the second time the timer is started for the first time, the operation goes back to the program by the electronic circuit. Therefore, it is a feature to set the desired rotation time and the reverse time of the advancing optionally is made freely allow full use of the action in progress.
