This control system has three kinds of mode of operations: automatic, manual, far away control.Preceding dual mode belongs to local control, controls opening/stopping of flour mill by guidance panel; A kind of Long-distance Control that belongs in back is controlled opening/stopping of flour mill by the computer in the flour mill control room.
When system powers on, enter the Long-distance Control mode automatically, " control far away " lamp is bright; system accepts the mill roller motor and the automatic level controling signal of remote control terminal, when the mill roller motor signal is high level, earlier from rolling; mill roller motor starts after 1 second, and " grinding roller " lamp is bright, at this moment; when control signal far away automatically was high level, " automatically " lamp was bright, and system enters automatic mode; mechanical feed does not have material from rolling, when automatic signal is low level; finish automatic mode, " automatically " lamp goes out, and feeding roller is shut down.When the mill roller motor signal was low level, mill roller motor stopped, and " grinding roller " lamp goes out.Wherein, at any time, the mill roller motor signal is a low level, and feeding roller and grinding roller are all shut down, and promptly system always shuts down.
Under prosecutor formula far away, the stop key on the keypad can directly enter local control mode under the situation that does not change the grinding roller state, and " control far away " lamp goes out; This locality (keyboard) control mode can always be shut down and enter to total stop key on the keypad, and remote-control lamp goes out.Under local control mode, by the Long-distance Control key, system can directly return the Long-distance Control mode under the situation that does not change grinding roller and feeding roller state.
If by by total stop key when the Long-distance Control mode switches to local control mode, this moment, mill roller motor stopped.If will enter automatic mode, then at first press mill roller motor and open key, " grinding roller " lamp is bright, mill roller motor starts, treat that grinding roller is stable after, press automatic key, " automatically " lamp is bright, flour mill just enters automatic operational mode.
If by by stop key when the Long-distance Control mode switches to local control mode, if will enter automatic mode, then press automatic key, " automatically " lamp is bright, flour mill just enters automatic operational mode.
Press the shutdown button, withdraw from automatic mode, " automatically " lamp goes out, and the feeding roller motor is shut down.If press total shutdown, feeding roller motor and mill roller motor are all shut down, and flour mill quits work.
When by by total stop key when the Long-distance Control mode switches to local control mode, this moment, mill roller motor stopped.If will enter manual mode, then at first press mill roller motor and open key, " grinding roller " lamp is bright, mill roller motor starts, treat that grinding roller is stable after, press manipulated key, " manually " lamp is bright, flour mill just enters manual mode of operation.
When by by stop key when the Long-distance Control mode switches to the Keyboard Control mode, if will enter manual mode, then press manipulated key, " manually " lamp is bright, flour mill just enters manual mode of operation.
Press the shutdown button, " manually " lamp goes out, and withdraws from manual mode, and the feeding roller motor is shut down.If press total shutdown, feeding roller motor and mill roller motor are all shut down, and flour mill quits work.
Be illustrated in figure 3 as the pneumatic circuit schematic diagram of flour mill, the snap joint of three air pipes is arranged in the side of each electric box, the joint that wherein is labeled as P connects source of the gas, two joints that are labeled as A, B connect respectively drive grinding roller from, close two air inlets that roll cylinder.Because per half platform flour mill needs two cylinders, therefore the gas that comes out from two joints of A, B needs respectively by receiving the air inlet of two cylinders after the tee pipe coupling shunting again.The tracheae that this pneumatic circuit uses is the flexible pipe of external diameter φ 6.
