In the present embodiment, the paddy / brown rice discrimination sensor 6 is constructed as follows. When the kernel is irradiated with near-infrared light that includes a wavelength range that is absorbed by moisture from the light emitting unit, the optical filter unit receives the reflected light from the grain, and only the wavelength range that is absorbed by moisture changes the optical filter unit. After passing through, it is sent to the light receiving section which is an infrared detecting element section, and is converted into a large and small voltage by the infrared detecting element section according to the amount of near-infrared light in the wavelength range, and the converted large and small voltage values are stored in the CPU. It is sent to the discriminating unit of the internal control unit 12 to discriminate between paddy and brown rice at a predetermined discriminating threshold value. Note that the detection wavelength range is not limited to the infrared light described above, and light including the wavelength range absorbed by moisture, or the amount of transmitted light or reflected light in other wavelength ranges of infrared light may cause the paddy.・ You may judge brown rice.

The control unit 12 with a built-in CPU has a sensor position sensor 13 for detecting the moving position of the paddy / brown rice discrimination sensor 6 and a paddy / brown rice discrimination sensor 6 via an input interface (not shown). Partition plate position sensor 14 that detects the moving position of partition plate 4, sensor origin position switch (swing side) 15a that detects the movement of paddy / brown rice discrimination sensor 6 to the most oscillating lower side 2d position, most oscillating upper side 2c position Origin position switch (upper side) 15b for detecting movement to the upper side, sensor origin position switch (upside for upper side) 15b, partition plate origin position switch (upside side) for detecting movement of the brown rice partition plate 4 to the most upper side 2c position. ) 16a, partition plate origin position switch for detecting movement of brown rice partition plate 4 to the most swaying lower side 2c position (swinging side)
16b, a grain sensor 17 for detecting the presence or absence of paddy in the paddy hopper of the paddy hulling device, a valve opening sensor 18 for detecting the opening of a paddy supply control valve for adjusting the grain supply amount to the paddy hulling device, and a paddy sorting Load current sensor 19 for detecting the load current value of main motor 23 for driving the device, operation switch 20, stop switch 2
1, an automatic / manual changeover switch 22, and a swing rotation sensor 25 for detecting swing rotation of the swing selection plate 2 are connected to the respective control units 12.

Further, the control unit 12 is provided with a sensor adjusting motor 8, a partition plate adjusting motor 9, a main motor 23 and the paddy supply adjusting device through an output interface (not shown) and a driving circuit. Paddy supply adjusting motor 24 for opening and closing the valve, and roll gap adjusting motor 2 for adjusting the gap of the paddy roll of the paddy hulling device.
6. A swing on / off motor 27 for turning on / off the swing clutch of the swing selecting plate 2 is connected to each.

Next, the control contents of the control unit 12 will be described. First, the light amount of the paddy / brown rice discrimination sensor 6 is adjusted,
The brown rice is adjusted to have a predetermined detection voltage. That is,
The oscillating sorting plate 2 is in a stable sorting state (from the upper swing side 2c to the lower swing side 2c).
When the grains are distributed over the entire width of d), the light amount adjustment control is started, the initial reference light amount adjustment voltage is set from the control unit 12, and is output to the paddy / brown rice discrimination sensor 6, and then the paddy / brown rice discrimination sensor. 6 moves from the most swaying upper side 2c to the swaying side 2d, the detection voltage of the portion estimated to be the brown rice distribution basin is detected, and it is compared whether or not the detection voltage value is within a predetermined reference voltage value range. When the light quantity reference voltage is higher or lower than the reference voltage value, the light quantity reference voltage is further adjusted to the decrease side or the increase side, and when the light quantity reference voltage falls within the range of the reference voltage value, the light quantity adjustment ends. Then, move from the uppermost rocking side 2c to the lowermost rocking side 2d,
The voltage values of brown rice, mixed rice and paddy are detected, and a boundary reference voltage value for determining the boundary between brown rice and mixed rice is set based on a predetermined calculation formula from the brown rice voltage value and the paddy voltage value. When the light amount adjustment control is completed, the process moves to the control of detecting the boundary position between the paddy and brown rice by the paddy / brown rice discrimination sensor 6. Then, the paddy / brown rice discrimination sensor 6 is moved to the uppermost rocking 2c side, and the sensor origin position switch (upward rocking) 15b is turned on to detect the movement to the uppermost rocking 2c. Next, the paddy / brown rice discrimination sensor 6 moves to the swaying side 2d, and the detection voltage value V of the paddy / brown rice discrimination sensor 6 is sequentially read by the control unit 12. Then, it is compared with the boundary reference voltage value, and when the detected voltage value is smaller than the boundary reference voltage value, 1 is applied to the sensor adjustment motor 8.
When the movement command to the step swing side 2d is issued, and when the detected voltage value is larger than the boundary reference voltage value, the sensor adjustment motor 8 is issued a move command to the one step swing side 2c and the paddy. -The brown rice discrimination sensor 6 is moved up and down one step and adjusted to the boundary position between paddy and brown rice. In this way, when the adjustment of the paddy / brown rice discrimination sensor 6 to the boundary position is completed, the uppermost 2
The moving distance from the c position to the boundary position of the paddy / brown rice is calculated by the detection data of the sensor position sensor 13, and then the moving command is output from the control unit 12 to the partition plate adjusting motor 8 and The brown rice partition plate 4 is moved and adjusted to the partition position related to the boundary detection position of the paddy / brown rice discrimination sensor 6.
Then, the brown rice partition plate 4 partitions the brown rice at a position where paddy is not mixed, and the brown rice is taken out of the machine.

Next, referring to FIG. 3, a paddy / brown rice discrimination sensor 6 and a brown rice partition plate 4 which are made when the sorting operation is temporarily stopped.
The operation stop control will be described. It is determined whether the automatic / manual switch 22 is the automatic side or the manual side. When the automatic / manual switch 22 is the automatic side, it is determined whether or not the operating switch 20 is ON. The sensor 17 detects the presence of grain, and the valve opening sensor 18
Detects the open state of the paddy supply control valve, and the partition plate position sensor 1
When the state 4 of removing the unpolished rice, which is the unpolished position of the unpolished rice partition 4 of the unpolished rice partition plate 4, is detected, the swing sorting device 1 determines that the unpolished rice is being extracted.

When the stop switch 21, which is a work stopping operation, is turned on while the work is being continued in such a state, it is determined that the work is in a temporarily stopped state, and a command for closing the paddy supply control valve of the hulling device is output. Rotating the paddy supply control motor 24 to close and control the paddy supply control valve, the paddy / brown rice boundary detection position of the paddy / brown rice discrimination sensor 6, the brown rice partitioning position of the brown rice partition plate 4, the brown rice switching valve (not shown) , The brown rice partitioned by the brown rice partition plate 4 is switched to the out-of-machine state or the in-machine circulation state.)
In that state, the motor stop command is output to stop the main motor 23.

Then, the paddy feed control valve of the paddy hulling device is closed, but the other sliding rice wind selecting parts and the actuator of the rocking and sorting device 1 are temporarily stopped while keeping the working state. Next, when the operation switch 20 is turned on, it is determined that the work that has been temporarily stopped is restarted, the work restart command is output, the main motor 23 is driven, and the paddy supply control valve is operated during the previous work. The opening is adjusted to the opening and the work is restarted. Therefore, the suspended hulling device, the falling rice wind selecting part, the drive part and the control device of the rocking sorting device 1 are restarted all at once, and the hulling and sorting work is restarted.
The operation of moving the brown rice discrimination sensor 6 to the boundary position and the operation of moving the brown rice partition plate 4 to the partition position can be omitted, and the hulling and sorting operation can be restarted quickly.

Incidentally, instead of the stop switch 22 described above,
The closing adjustment of the paddy supply control valve may be adopted for the work stop operation. In this case, it is determined that the work is temporarily stopped by detecting the presence of the grain of the grain sensor 17 and the closing adjustment of the paddy supply control valve, and the brown rice partition plate 4, the paddy / brown rice discrimination sensor 6 and the like are left at the positions, The main motor 23 will be stopped.

Next, another embodiment of the work temporary stop control will be described with reference to FIG. During the paddy sorting operation, the swing rotation sensor 25 detects the swinging rotation state of the swing sorting plate 2, and when the swinging device is rotating, the valve opening sensor 18 causes the paddy supply control valve. Valve opening sensor 1
When 8 detects the closing of the paddy supply control valve, it judges that the rocking sorting work is temporarily stopped, outputs a rocking cut command, and outputs the rocking device through the rocking on / off motor 27. Disengage the clutch to operate and stop swinging. Next, when the valve opening sensor 18 detects the opening of the paddy supply control valve, it is determined that the work is restarted, a swing-on command is output, and the swing-on / off motor 27 is driven to swing. , Resume swing sorting work.

During the rocking / sorting operation, when the valve opening sensor 18 detects the open state of the paddy supply control valve and the Glen sensor 17 detects no paddy, it is determined that the work is temporarily stopped, and the rocking is turned on / off.
The cutting motor 27 is oscillated and cut, the oscillating device is stopped, the control of the unpolished rice partition plate 4 by the paddy / brown rice discrimination sensor 6 is also stopped, and then, after a predetermined time (for example, 20 seconds), the grain is removed. When the sensor 17 detects the presence of paddy, it is determined that the work is restarted, the swing input is output, and the swing input / cut motor 27 is operated to swing to restart the swing, and the paddy / brown rice is discriminated. The detection of the boundary position between the paddy and brown rice by the sensor 6 and the partition control of the brown rice partition plate 4 associated therewith are restarted.

If the grain sensor 17 does not detect the presence of paddy after a predetermined time, it is determined that the work is completed, and the process is terminated. The work end process is, for example, as follows. When the grain sensor 17 detects the absence of paddy, the brown rice partition plate 4 is moved and adjusted to the uppermost rocking position, and the whole amount of the grains discharged from the rocking sorting plate 2 is returned to the paddy hulling device and hulled, and then, It is wind-selected by the slide-down rice wind selection unit and is supplied to the swing selection plate 2. Next, the paddy / brown rice discrimination sensor 6 is moved and adjusted to the most swaying lower side 2d, and the paddy / brown rice discrimination sensor 6 detects the grain / brown rice ratio of the grains distributed in the most swaying lower side 2d, and the detected paddy / brown rice is detected. When the brown rice ratio is higher than the reference value, the brown rice partition plate 4 moves a predetermined distance from the uppermost rocking upper side 2c to the lower rocking side 2
Move to the brown rice partitioning position of d, and swing the upper side 2 of the swing sorting plate 2.
Brown rice that is distributed unevenly in c is partitioned by a brown rice partition plate 4, and a brown rice switching valve (not shown) that is switched to the unloading side by a brown rice switching valve motor (not shown), brown rice fried machine It is taken out of the machine through.

During the work ending process as described above, if the value detected by the partition plate position sensor 14 does not change by a certain value or more after the movement command is issued to the partition plate adjustment motor 11, it is determined to be abnormal. After a certain time, the swing is stopped or the main motor 23 is stopped. Then, it is possible to prevent problems such as paddy mixed with brown rice. As described above, when it is determined that the work is temporarily stopped, the paddy / brown rice discrimination sensor 6 is at the boundary detection position, and the brown rice partition plate 4 is still swinging at the partition position. The brown rice partition plate 4 allows the brown rice to be taken out of the partition machine without adjusting the paddy / brown rice discrimination sensor 6 and the brown rice partition plate 4 at the time of restart, and the work efficiency is improved.

Next, another embodiment of the work ending process will be described with reference to FIG. During work, the automatic / manual switch 22 determines whether it is an automatic operation or a manual operation. In the case of automatic operation, the operation switch 20 determines whether it is in operation. With the detection of the presence of paddy of the sensor 17, and the detection of the partition plate position sensor 14 following this,
When it is detected that the brown rice partition plate 4 is at the partition position, the swing sorting device 1 determines that the brown rice removing and sorting operation is in progress.

When the valve opening sensor 18 detects that the paddy supply control valve is closed during such a brown rice extraction operation, it is determined that the operation is completed, the operation is terminated, and the operation is terminated. A motor stop output is output and the main motor 23 is stopped. With such a configuration,
Even when different types of paddy are supplied when work is resumed,
This is convenient because it can prevent the mixing of paddy of other varieties.

[0026]

As described above, according to the present invention, when it is determined that the work is temporarily stopped, the main motor 23 is stopped while the brown rice partition plate 4 is stopped at the partition position as it is.
When the work is resumed, the brown rice discharged from the brown rice partition plate 2 is partitioned by the brown rice partition plate 4 located at the partition position at the time of the previous work, and can be immediately taken out of the machine, and the partition position of the brown rice partition plate 4 when the work is restarted. Without any adjustment, the hulling and sorting work can be restarted quickly and the work efficiency is improved.
