The associated run / stop switch 32 is connected to an arithmetic control unit 41 including a CPU including a control unit, an arithmetic unit and a register unit, and a memory unit of a program memory and an arithmetic memory via an input / output interface 40. The removal rate indicator needle 36 that is connected and can be adjusted by the removal rate adjustment volume 35 is connected to the arithmetic control unit 41 via the A / D conversion circuit, and the automatic / manual switch 31 is connected to the arithmetic control unit 41. It is connected.

The load current sensor 33 is connected to the arithmetic control unit 41 via the A / D conversion circuit, and the arithmetic control unit 41 is connected.
Is connected to the load current indicating needle 34 via the D / A conversion circuit. Further, the original power supply voltage 43 is converted into a voltage converter
A shutter sensor 45, which is connected to the arithmetic and control unit 41 via the above, and detects opening and closing of a shutter (not shown) provided below the paddy hopper 6, is connected to the arithmetic and control unit 41, and also to the paddy hopper. A valve opening sensor 46 for detecting the open / closed state of a paddy supply control valve (not shown) provided at the lower part of 6 is connected to the arithmetic control unit 41 via an A / D conversion circuit.

The arithmetic control unit 41 also includes a buffer 4
7, a main motor drive circuit 48 for turning on / off a main motor (not shown) for driving a hull sorter through a relay, and an open drive circuit 49 for the roll gap adjusting motor 29. , The closing drive circuit 50 of the roll gap adjusting motor 29 is connected to each of them. Further, an operation circuit of the buzzer 51 is connected to the arithmetic control unit 41. Reference numeral 52 denotes a non-volatile memory connected to the arithmetic control unit 41 via an input / output circuit,
Reference numeral 53 is a removal rate sensor for detecting the removal rate of the paddy rice on the hulling rolls 7, 7.

Next, the control contents of the arithmetic control unit 41 will be described. First, the removal rate adjusting volume 35 is operated, and the removal rate limb needle 36 is adjusted to the desired low, standard, or high position of the removal rate character display zone 38 to obtain the desired reference removal rate. The rate is set, the automatic / manual switch 31 is switched to the automatic side, the operation / stop switch 32 is pressed to the operating side, each rotating part of the machine body is driven, and the hulling work is started.

Next, the initial clearance setting control of the hulling rolls 7 is first performed. That is, a roll gap opening command signal from the arithmetic control unit 41 is output to the roll gap adjusting motor 29 to open the gap between the hulling rolls 7 and 7 for a predetermined time, and the load current sensor 33. Detects a non-contact state in which the detected load current value does not change, a roll gap close command signal is output and the roll gap is closed and adjusted. Next, when the load current sensor 33 detects an increase in the load current value and judges that the hulling rolls 7 and 7 are in slight contact, a roll gap opening command signal is output, and the roll gap adjusting motor is output. 29 is open-controlled for a predetermined time and initialized to a predetermined roll gap (for example, 1 mm). Next, an opening command signal of a paddy supply control valve (not shown) is output from the arithmetic and control unit 41, and an initial opening setting for opening the paddy supply control valve to a predetermined opening (for example, 10 mm) is set. Is started.

Next, a supply amount setting switch (not shown)
A valve opening control command signal is output based on the adjustment setting of the supply amount of, and the paddy supply control valve is adjusted to the valve opening corresponding to the set efficiency. Next, the control shifts to the roll gap adjustment control based on the removal rate standard. That is, the light amount of the removal rate sensor 29 is adjusted so that the light amount of the light emitting element is adjusted to be suitable for distinguishing paddy rice and brown rice from the declining rice, and the voltage of the grain passing through the removal rate sensor 29 is adjusted. When the signal is input to the arithmetic control unit 41 and the voltage signal of a predetermined number of sample particles is read, the removal rate is calculated.

Next, the reference depletion rate set by the depletion rate adjusting volume 35 and the calculated depletion rate are compared, and if the calculated depletion rate is higher (or lower) than the reference depletion rate. ,
An open adjustment (or close adjustment) command signal is output from the arithmetic control unit 41, the roll gap adjustment motor 29 is normally rotated (or reversely rotated), and the roll gap is open adjusted (or closed adjusted). Then, a return to the standard removal rate is achieved. If the calculated removal rate is within the range of the reference removal rate, the control command signal is not output and the hulling work is continued while maintaining the roll gap as it is.

In performing the removal rate control based on the removal rate detected by the removal rate sensor 53, the load current value at the adjusted position of the removal rate indicator needle 36 is set to the minimum load current value. By so doing, even when the removal rate sensor 53 does not properly detect the removal rate, it will not be hulled on the side lower than the load current value, and an extremely low removal rate will be achieved. Prevents and improves work efficiency. Further, in place of the above-mentioned automatic clearance adjustment system based on the removal rate, the load current value of the motor driving the hull roll is detected, and the detected load current value is the reference load current. A roll gap adjusting method based on a load current value for adjusting the roll gap so that the value becomes a value may be adopted. Although the hulling and sorting work proceeds as described above, during normal operation, the lighting control signal is output from the arithmetic and control unit 41, the illumination unit 32a of the run / stop switch 32 is turned on, and the hulling operation is performed. When the main motor (not shown) that drives the slide sorting machine is stopped, the illumination unit 32a is turned off. Further, when an abnormality such as the load current sensor 33 detecting an overload current value occurs, an abnormality display command signal is output, the illumination unit 32a is turned on and off, and the buzzer 51
A buzzer operation command signal is output to the buzzer 51, and the buzzer 51 is operated to notify the operator of the abnormality. At the same time, a stop command signal for the main motor is output and the main motor is turned off.
Next stop.

Next, another embodiment of displaying an abnormality will be described with reference to FIGS. At the start of work, the removal rate indicator needle 36 operated by the removal rate adjustment volume 35
Is located between 8 and 15 of the removal rate numeral display zone 37 or is located in the check mode portion 54, depending on whether the hulling operation is selected or the check mode is selected. It is determined whether or not (S10). When the check mode is selected, the latest abnormality content stored in the non-volatile memory 52 over time is displayed (S2).
0). This abnormality display is configured to be displayed by the number of the moving position of the load current indicating needle 34 corresponding to the type of abnormality.
For example, as shown in FIG. 6, the source power supply voltage is out of the proper range, the valve opening sensor 46 is abnormal, the shutter sensor 4 is abnormal.
In the case of the abnormality of No. 5 and the abnormality of the main motor overload, the load current indicating needle 34 is moved to the 8, 9, 10, 11 position corresponding to each and the abnormal portion is displayed. Is.

When the normal hulling work is selected, it is judged whether the operation / stop switch 32 is in operation or in stop (S30).
Turn on the illumination unit 32a of the stop switch 32 (S40)
Then, the hulling operation is started (S50). Then automatic /
Regarding the manual switch 31, it is determined whether automatic operation / manual operation is performed (S60), and if it is manual operation, automatic adjustment of the automatic adjustment unit is stopped, and hulling work is performed while manually adjusting each adjustment unit.

In the case of automatic operation, it is judged at every predetermined time whether or not an abnormality has occurred (S70). When no abnormality has occurred, the work is continued while the adjusting portion is automatically adjusted, Run / stop switch 32 every predetermined time
The operation / stop in step S80 is determined (S80). If the operation is stopped, the paddy sorting machine is stopped, and if the operation is stopped, the automatic operation is further continued.

When an abnormality occurs, the arithmetic control section 41 issues an abnormal blinking command, and the illumination section 32a of the run / stop switch 32 blinks to notify the abnormality (S9).
0), and then the load current indicating needle 34 from the arithmetic and control unit 41.
The voltage for driving the load current needle corresponding to the abnormality is output to, the load current value indicating needle 34 moves to the corresponding specific position to display the abnormality of the numerical value (S100), and then the content of the abnormality is nonvolatile. It is stored in the memory 52 (S110) and the automatic operation is stopped (S120).

In this way, when an abnormality occurs, the removal rate adjusting volume 35 is operated to move the removal rate indicating needle 36 to the check mode portion 54, and when the check mode is selected, Depending on the type of abnormality, the load current indicator needle 34 moves to the removal rate numerical display zone 37 to display the content of the abnormality numerically, so the type of abnormality can be easily known and maintenance becomes easy. .

Next, the operation of the embodiment shown in FIG. 1 will be described. When performing hulling work, the raw hull is supplied to the hull hopper 6 of the hulling unit 1, a power switch (not shown) and an operation / stop switch 32 are turned on, and each rotating unit of the hulling sorting machine is driven. . Then, when paddy is fed from the paddy hopper 6 to the paddy rolls 7, 7 of the paddy section 1, the paddy rice is fed to the downward paddy-rice selecting passage 10 to be wind-selected and lightly paddy. Is discharged to the outside of the machine through a suction fan 13 and a dust exhaust tube 14, and the mixed rice of heavy brown rice and paddy is dropped and sorted on the sliding-down rice gutter 12.
