In the process that the photoelectric trigger plate 6 moves towards the origin inductor 14, when the photoelectric trigger plate 6 is close to the origin inductor 14, if the sudden situation of power failure occurs, the photoelectric trigger plate 6 continuously moves backwards for a certain distance due to the inertia effect of the rotation of the motor, at this time, the origin inductor 14 cannot sense the photoelectric trigger plate 6 due to the power failure, so that the photoelectric trigger plate 6 stays in the safety interval between the origin inductor 14 and the rear limit inductor 16, after the power is restored, the motor reverse rotation signal is not sent to the PLC control system because the origin inductor 14 does not sense the photoelectric trigger plate 6, when the photoelectric trigger plate 6 continuously moves to the rear limit inductor 16, the rear limit inductor 16 sends a signal to the PLC control system to control the motor to reversely rotate, so as to drive the origin of the photoelectric trigger plate 6 to return to the inductor 14, as the starting point location for the filling operation. In the normal filling working process, the origin sensor 14 is always used as the starting position of the photoelectric trigger plate 6, the displacement of the photoelectric trigger plate 6 between the front limit sensor 15 and the origin sensor 14 is controlled by the PLC control system built-in program and the feedback signal of the encoder, and the filling precision is ensured through the displacement controlled by the origin sensor 14 and the PLC control system.
