The paddle inserted in a hopper rotates slowly to detect material presence.
Spindle and paddle, connected to the motor via the slip mechanism, slowly rotates as the motor rotates.
Paddle rotation is impeded by the material, and the motor revolves with the spindle as its axis. The motor revolution causes the pin on the motor to actuate the microswitch, turning on the signal output and turning off the motor rotation. This gives an output signal and stops the motor revolution simultaneously.
When the material descends and the paddle is no longer covered by it, the pin on the motor returns to its original position by the spring force, causing the microswitch to reset and then the motor and the paddle to resume rotation.
When the spindle is forced to rotate due to for example downward flow, the slip mechanism on the connection of the motor shaft and the spindle makes the spindle ‘slip’. This prevents forced rotation of the motor and protects the motor from damage.
