Further, in the case of the “single” mode, the hulling / sorting operation is not turned on even if the start switch SW14 is pressed.

 The flowchart will be described in order from FIG.

First, at the start, it is determined whether the operation power supply is "on" or "off" (S1). In the case of “OFF”, the control circuit, each solenoid valve (SV) and the sensor (LVS) do not operate at all (S2). When the operation power is "ON", the set value of each timer is read (S3). Then, whether or not grains are clogged in the sensor provided in each tank is checked for each time set by the timer (S4). When a grain is present at the sensor, the pilot lamp of the corresponding control panel is turned on.

Next, it is determined whether the supply amount adjustment switch SW25 on the control panel P is an automatic side or a manual side (S5). In the case of manual operation, the supply amount adjustment motor Mθ-1 is rotated forward or backward according to the manual set value. The position of the supply control valve is adjusted to the set value (S6).

If the supply amount adjustment switch SW25 is automatic, it is checked whether the sorter tank shutter SV5 of the sorter tank 2 is opened or closed by the shutter open / close switch SW26 (S7). Set the sorter tank shutter SV5 to the blackout (S9) or energized (S8) state.

Next, the removal of the three product tanks 24, 25, and 26 is selected by the tank selection switch SW28 (S10). When the tank selection switch SW28 is turned on in accordance with this, the product tank 24 is selected. The product elevator switching valve SV7 is energized to the pull-in side (S14), and the product elevator switching valve SV8 is also energized (S15) and guided to the product tank 24.

Next, when the tank selection switch SW28 is OFF, one of the product tanks 25 and 26 is checked (S11). When the product tank 25 is selected, the product elevator switching valve SV7 is energized to the drawing side ( S13), Product lift switching valve SV8
Is supplied to the extrusion side (S16). When the product tank 26 is selected, the product elevator switch valve SV7 is energized to the pushing side (S12).

Next, in FIG. 5, it is checked whether any of the thermal relays of the drive motors M1 to M16 is operating (S39), and if an overload state is indicated, the process returns to the start of control (S40). If the thermal relay is not operating, it is checked whether the independent / interlocked changeover switch SW32 is “independent” or “interlocked” (S41). If “independent”, the independent operation switches SW33 to It is checked whether or not 46 is a full stop (S42), and only in the case of a full stop, it can be switched to "single", and the control returns to the start and goes on the control chart until the full stop.

Then, only when the operation is completely stopped, the individual operation is stopped by the individual operation switches SW33 to SW46 (S43).

Conversely, if the single / interlock switch SW32 is “single”, the “interlock” operation is not performed, and the hulling / sorting operation does not start.

In the case of “interlock”, the operation selector valve switch SW12
However, any one of "remote", "manual" and "automatic" is checked (S44), and if it is "manual", control is performed by a "manual" operation routine (S45). In the case of "remote", it is checked whether the separately provided remote control switch SW1 is "on" (S47), and then the drive motor M of the blower 14 is turned on.
It is checked whether 1 is in operation (S48). If the drive motor M1 is operating, the alarm is turned off (S5
1), and the drive motor M1 of the blower 14 and the product lift 16
Drive motor M2 and hydraulic motor for elevator 15 for grain sorter
M3 is driven (S54).

When the drive motor M1 is not operating, an intermittent sound by an alarm buzzer is sounded (S49), and after 5 seconds, the buzzer is stopped (S50).

In the case of "automatic", it is checked whether the start switch SW14 is ON (S46), and then the drive motor M1,
M2 and M3 are driven (S54). When the start switch SW14 is OFF (S
46) If the stop switch SW15 is ON (S52), the automatic stop routine starts (S53), and the stop switch SW15 is OFF.
If so, return to the start.

Next, in the flowchart of FIG. 6, it is checked whether or not the drive motor M4 of the grain sorter 30 is "forward rotation" (S66). If it is not "forward rotation", it is checked whether it is "reverse rotation" (S57). If neither is the case, the drive motor M4 is stopped.

If the drive motor M4 is stopped, it is checked whether the time set by the "forward rotation" time setting timer M4T1 has elapsed (S58), and if the "forward rotation" time has elapsed (S64). ), The drive motor M13 of the sorting machine 6 is stopped.

If the "forward rotation" time has not elapsed, it is checked whether or not two seconds have elapsed after the drive motor M4 stopped (S59). If the two seconds have elapsed, the grain sorter 30 is driven. The motor M4 starts normal rotation (S60).

Next, it is checked whether the reverse rotation interval switch SW18 is ON or OFF (S61). If the reverse rotation interval switch SW18 is ON, the "forward rotation" time timer M4T1 is started (S62). S56) It is checked whether the "forward rotation" time set by the timer M4T1 has elapsed (S63), and the timer M4T
After the elapse of the time set in step 1, the drive motor M13 of the sorting machine 6 is stopped (S64), the timer M4T1 is stopped and cleared, and the timer M13T1 is started (S65).

After the time set by the timer M13T1 has elapsed (S6
6) Stop the drive motor M4 of the grain sorter 30 and set the timer M
Stop clear 13T1 (S67). When two seconds have elapsed from the time set by the timer (S68), the drive motor M4 is "reversed" and the timer M4T2 in which the "reverse" time is set is started.

After the "reverse" time set by the timer M4T2 has elapsed (S70), the drive motor M4 of the grain sorter 30 is stopped, the timer M4T2 is stopped and cleared (S71), and then it is checked whether 2 seconds have elapsed. Forward rotation ”.

When switching from "forward rotation" to "reverse rotation", the sorting machine 6 is stopped because the inside of the grain sorter 30 is to be clogged. Therefore, the operation of stopping the sorting machine 6 is not performed.

The interval for the "reverse rotation" is set by the reverse rotation interval selection switch SW18.
In this case, no reversal is performed. The "forward rotation" time is set to about 3 hours, and the "reverse rotation" time is set to about 3 minutes.

Then, the forward motor is stopped, and the drive motor of the next stage is turned off only two seconds after the drive motor of the previous stage is turned off.

Therefore, the drive motor of the preceding stage cannot be stopped even if the switch is OFF.

That is, when the manual stop is pressed (S182), the drive motor M15 of the pool tank removal conveyor 10 is stopped (S183), and after two seconds (S184), the drive motor M14 of the pool tank removal elevator 12 is stopped (S185). ) After 2 seconds (S186),
The drive motor M13 of the sorting machine 6 is stopped (S187), and after 2 seconds (S189), the drive motor M11 of the hulling wind sorter 4 is stopped (S190), and after 2 seconds (S191), the vibration is started. Conveyor 1
The drive motors M10 and M7 are stopped (S192), and after 2 seconds (S193), the drive motor M9 of the raw material elevator 13 is stopped (S194), and after 2 seconds (S195), the elevator 5 for the sorting machine is stopped. Drive motor M8 is stopped (S196), and two seconds later (S202), the drive motor M15 of the pool tank take-out conveyor 10 is stopped (S196).
203) After 2 seconds (S204), drive motor M of grain sorter 30
4 is stopped (S205), and after 2 seconds (S206), the drive motor M3 of the immature grain take-out device is stopped (S207), and after 2 seconds (S208), the drive motor M2 of the product lift 16 is stopped. (S209) Two seconds later (S210), the drive motor of the blower 14
M1 is stopped (S211).

(F) Effects of the Invention The present invention is configured as described above, and has the following effects.

An independent operation switch that enables a motor of a device that drives each device of the plant to operate independently, as claimed in claim (1).
In a configuration in which SW33 to 46 are provided and a single / interlocked switch SW32 is provided for switching between “independent” operation of each motor by the individual operation switches SW33 to 46 and “interlock” operation of each motor, When the “Single” mode is selected by SW32, the independent operation switch SW33
Only when all of the switches are OFF.
Since independent operation by one of the six units was enabled, if only the motors were sequentially driven in the "interlocked" mode, it would not be possible to operate alone when checking and repairing each individual device. However, in the present invention,
Prior to selecting "Automatic" and "Manual" with the operation selector valve switch SW12, it is possible to select "Interlocked" or "Independent" with the independent / interlocked switch SW32, so in inspection and repair of each individual device, It became possible to drive alone.

Further, when the “independent” mode is selected, only the single motor can be driven, so only when all the individual operation switches SW33 to 46 are on the stop side, the individual operation switches SW33 to In order to make it possible to operate only one of the 46, the "independent" operation was enabled only when the individual operation switches SW33 to 46 were completely stopped.

As a result, only a single motor can be driven, and safety of inspection and repair can be improved.

In the control for providing a plurality of motors for driving each device of the plant as described in claim (2) and operating the plurality of motors in an interlocked manner and after a certain time, performing "automatic" operation in order, In this case, since the drive motor M1 of the blower 14 is configured to be operated first, the blower 14 can be driven prior to the operation of all the devices. The dust and dirty air that had been blown up were blown up all at once, but these could be sucked by the blower 14 and the working environment of the operator could be improved.
