DESCRIPTION OF THE PREFERRED EMBODIMENTS The objects and means of the present invention are as described above, and the configuration of the embodiment shown in the accompanying drawings will be described.
In FIG. 1, the whole structure of the hulling / sorting device and the flow of grains will be described. The paddy after being dried by the dryer is stored in a pool tank 8, and the pool tank 8 is composed of a number of tanks provided in parallel. At the lower part of the pool tank 8, there is provided a supply amount control valve 11 for adjusting the drop amount to the pool tank take-out conveyor 10, and the pool tank take-out conveyor 10 is driven by a drive motor M15.

[0006] The paddy is fed to a pool tank removal conveyor 10.
From, it is fried by the pool tank removal elevator 12,
It is branched and supplied to the adjusting tank 9 and the roll tank 1. When supplied to the control tank 9, after being discharged, the raw material is passed from the raw material tank 32 through the raw material elevator 13 and further through the raw material elevator switching valve SV 2, one of which is in the “extraction” direction where the different-type extraction tank 19 is located, and the other is the roll tank. 1 is switched to the "circulation" direction, which is the direction supplied to the "1".

[0007] The reason for the provision of the heterogeneous removal tank 19 and the raw material elevator switching valve SV2 is that when the lot of the previous owner's paddy is finished, all the paddy is converted to brown rice and then flown to the final step. Is ideal, but because the amount of processing is reduced, it cannot be processed by the hulling wind sorter 4 or cannot be sorted to the brown rice side by the rocking sorter, and a certain amount is inevitable. The raw material elevator 13 → the raw material elevator switching valve SV2 → the roll tank 1 → the hulling wind sorter 4 → the elevator for the sorter 5 → the sorter 6 → the material lift 13 remains in a state of continuing circulation. Since the processing of these circulating materials does not end indefinitely, the circulating materials are provided to switch the raw material elevator switching valve SV2 to "take out" and to take them out into the different kind taking-out tank 19.

An adjustment tank upper limit sensor LVS41 is disposed above the adjustment tank 9, a different extraction tank upper limit sensor LVS31 is disposed in the different extraction tank 19, and a source tank shutter SV1 is disposed in the source tank 32.

Next, it is checked whether the motor switch SW32 is "single" or "interlocked" (S40). If "single", the switches SW33 to SW4 of the respective drive motors are checked.
It is checked whether or not 6 is a full stop (S41), and only in the case of a full stop, it can be switched to "independent". The individual operation is stopped by the switches SW33 to SW46 (S42), and the control is started. Return to Further, when the raw material tank 32 is “single”, the “grinding / sorting” operation does not start because the “interlocking” operation is not performed.

In the case of "interlock", as shown in FIG. 5, the operation switching valve switch SW12 is set to "remote", "manual", "automatic".
Is checked (S43). In the case of "manual", control is performed by a "manual operation" routine described later. In the case of "remote", the lamp 55 is turned on (S44). It is checked whether or not the provided remote control switch SW1 is "ON" (S45). If "OFF", the process proceeds to the "automatic stop" routine to be described later, and the operation switching valve switch SW12 is set to "automatic". The start switch SW14 is turned off (S46), and the stop switch SW15 is turned on (S4).
Also in the case of 7), the process proceeds to the "automatic stop" routine. When the stop switch SW15 is OFF, the process returns to the start.

When the operation switching valve switch SW12 is "remote" and the remote control switch SW1 is "on", and when the operation switching valve switch SW12 is "automatic" and the start switch SW14 is on, the exit shutter switch is provided. S
It is checked whether W26 is "open" or "closed" (S48). If it is closed, the lamp 99 flashes (S49) and the process returns to the start. If it is open, the material lift switch SW23
Is switched to the "remove" side (S
50), the lamp 94 blinks on the "remove" side (S5).
1) Then return to the start. If it is not the "remove" side, the lamp built in the start switch SW14 is turned on to check whether the drive motor M1 of the blower 14 is operating (S53), and the drive motor M1 is not operated. In this case, an intermittent sound by an alarm buzzer is sounded (S54), and if 5 seconds have not elapsed (S55), the process returns to the start.
Is driven to turn on the lamp 71 (S56). And
After the drive motor M1 of the blower 14 is driven, the drive motor M2 of the product lift 16 and the drive motor M3 of the grain sorter lift 15 are driven every two seconds sequentially (S57).

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" (S58). If it is not "forward rotation", it is checked whether it is "reverse rotation" (S59). If neither is the case, the drive motor M4 is stopped. If the drive motor M4 is stopped, it is checked whether or not the time set by the "forward rotation" time setting timer M4T1 has elapsed (S60). In S66), 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 2 seconds have elapsed since the drive motor M4 stopped (S61). If 2 seconds have elapsed, the drive of the grain sorter 30 is performed. The normal rotation of the motor M4 is started, and the lamp 74 is turned on (S60).

Next, it is checked whether the reverse rotation interval switch SW18 is ON or OFF (S63).

First, it is checked whether it is "automatic", and if it is "automatic", it is checked whether the drive motor M13 for driving the sorting machine 6 has passed for a certain time after the start of operation, and then the supply control valve 3 Supply adjusting motor M
Start 0-1 and sort tank lower limit sensor LVS4
Is OFF, the amount of storage in the sorter tank 2 is small, and the supply control motor M0-1 rotates the supply control valve 3 to the left until the supply multi-end sensor LS2 turns ON.
Drive.

If the sorting tank upper limit sensor LVS3 is ON and the lower limit sensor LS1 is OFF, the supply amount can be reduced. However, when the discharge of the sorting machine 6 is circulated, When the discharge shutter of the machine tank 2 is closed (SW26 is closed),
Even if it is reduced, it will only accumulate in the sorter tank 2 and overflow, so the supply itself is stopped without controlling the supply amount in the decreasing direction. Then, it can be discharged from the sorter 6, and when the discharge shutter of the sorter tank 2 is open, the amount of storage in the sorter tank 2 is large, so the supply is adjusted until the low supply end sensor LS1 is turned on. The supply amount adjusting motor M0-1 is driven to rotate the valve 3 clockwise.

Next, as shown in FIG. 10, in the routine for discharging to the different kind removal tank 19, it is checked whether the raw material lift switch SW23 for operating the raw material lift switch valve SV2 is "circulation" or "discharge". (S129) In the case of the "circulation" side, the timer SV1T is stopped and cleared (S130), the raw material elevator switch valve SV2 is switched to the "circulation" side, the lamp 94 is turned off, and the lamp 93 is turned on (S131). In the case of “extraction”, the different type extraction tank upper limit sensor LVS31 is checked (S132),
When the different kind removal tank upper limit sensor LVS31 is OFF, the different kind removal tank 19 is not filled, so that the material tank shutter SV1 of the material tank 32 is first closed and the material shutter lamp 91 is turned off (S13).
3) After a certain period of time, “extract” the material lifter switching valve SV2
Side (S134), the lamp 94 is turned on and the 93 is turned off.

When the different kind removal tank upper limit sensor LVS31 of the different kind taking tank 19 is ON, it is full, so the alarm buzzer is sounded (S135), and the material elevator switching valve SV2 is automatically set to the "circulation" side. Switching is performed (S131). Then, it is checked whether the rubber roll 7 is worn down (S136). If a signal is output for 3 seconds or more (S137), an alarm is issued (S138), and the lamp 63 is turned off.
Is blinked, the power of the SV3 is cut off so as to close the roll shutter, the lamp 95 is turned off, and the energization of the rubber roll crimping valve SV4 is stopped so as to release the rubber roll crimping (S139). Then, it returns to the start, and the above is repeated.

FIG. 11 shows a flowchart in the case where the hulling / sorting device is automatically stopped. That is, when the stop switch SW15 is pressed, the built-in lamp is turned on, the start lamp is turned off, and the material tank shutter SV1 is closed so that the shutters are closed in order from the front of the order in which the grains flow. 91 is turned off, then the raw material elevator switch valve SV2 is closed to turn off the lamp 94, then the roll tank shutter SV3 is closed and the lamp 95 is turned off, and after a certain time of the timer SV3T has elapsed, the rubber roll pressing valve SV4 is turned off. (S14)
0).

After 5 seconds from the stoppage of the rubber roll pressing valve SV4 (S141), the drive motor M15 of the pool tank take-out conveyor 10 is stopped (S142), and every 2 seconds after the stop of the drive motor M15, the pool tank take-off elevator is moved. 12 drive motor M14, sorter 6 drive motor M13, hulling wind separator 4 drive motor M11, vibrating conveyors 17 and 18, drive motor M10, raw material elevator 1
3, a drive motor M9 of the elevator 5 for the sorter, a drive motor M6 of the elevator 15 for the grain sorter, a drive motor M5 of the stone extractor 31, a drive motor M4 of the grain sorter 30, a immature grain take-out tank 21, The drive motor M3 of 23, the drive motor M2 of the product elevator 16 and finally the drive motor M1 of the blower 14 are sequentially stopped, and at the same time, the lamp indicating the drive is turned off (S14).
3).

FIG. 12 shows a flowchart in the case of "manual" stop, which is the same as the routine after the stop of the automatic stop of the raw material tank shutter SV1, the raw material elevator switching valve SV2, and the roll tank shutter SV3. Then, the drive motor M15 of the pool tank take-out conveyer 10 is stopped (S145), and thereafter each motor is sequentially stopped every two seconds, and the lamp is turned off.

FIG. 13 shows a case where the vehicle is operated "manually".
Misao the operation switching valve switch SW12 is switched to "manual"
When the operation power switch SW11 is switched to the "ON" side, the lamp 54 is turned on and the lamps 53 and 55 are turned off (S15).
0), Timer M for reversing interval of grain sorter motor M4
4T1 and the timer M4T2 for time setting are stop-cleared (S151), and a different kind removal interval timer M13T3.
Then, the different removal time timer M13T4 is stop-cleared (S152), and it is checked whether the start switch SW14 is ON (S153). If the stop switch SW15 is ON without being turned ON (S154),
The built-in lamp is turned on and the start lamp is turned off (S155). The process proceeds to the "manual stop" routine. If the stop switch SW15 is OFF, the process returns to the start and enters the standby state, and the switches SW33 to SW46 operate independently. /
Stopping is possible. Then, the activation switch SW14
Is turned on, the manual lamp 54 is flickered so as not to be activated.

[0052]

As described above, the present invention has the following advantages. It is checked at every time set by a timer whether or not a grain is clogged in a sensor portion provided in each tank (S7). If grain is present in the sensor portion, a corresponding control panel is checked. Pilot lamps (58, 59, 62 and 111)
To 114) is turned on or blinks, and the timer is stopped and cleared (S8). If there is no timer, the lamp is turned off and each timer is started (S9), so that the timer remains during the previous threshing and hulling work. It was possible to reliably confirm whether or not there was any grain, and the remaining grain and the grain to be processed next were not mixed. Also, if the previously treated grains were spoiled or degraded, they would no longer be mixed with new grains.
