A monitor display 59 is connected to the controller 41 via a display output circuit, and a swing rotation adjusting motor 60 is connected to the controller 41 via a rotation command output circuit. In this configuration, the rotation information of the swing rotation adjustment motor 60 is input to the control unit 41 via a rotation pulse input circuit. Further, a serial data receiving circuit 61 and a serial data transmitting circuit 62 are connected to the control section 41, and a nonvolatile memory 63 is connected to a memory section of the control section 41.

FIG. 3 shows an operation panel 64 of the control unit 41. Next, control contents of the control unit 41 will be described. First, light amount control of the rice / brown rice discrimination sensor 30 is performed, and brown rice is adjusted to have a predetermined detection voltage value.
Next, the process proceeds to the boundary position detection control of the paddy / brown rice discrimination sensor 30.

When the detected peak voltage value is detected by the rice / brown rice discrimination sensor 30, the number of times of detection of the detected rice peak voltage within a predetermined time is compared with a control reference value, and the detected rice peak voltage is detected. When the voltage count is large (or small),
The detection operation is continued while the brown rice discrimination sensor 30 is moved up and down a predetermined distance 15c (or 15d), and the position where the number of times of detection of the paddy detection peak voltage value falls within the range of the control reference value is determined. The boundary detection position of paddy / brown rice. Next, based on this boundary detection position, the partition position of the brown rice partition plate 4 is calculated, and the brown rice partition plate 18 is moved.

Next, the control of the brown rice partition plate 18 based on FIG. 5 will be described. During the above-mentioned brown rice partition plate movement control, the boundary position of the paddy / brown rice is detected while moving to the swinging side 15c or the swinging side 15d. Each time it is stored at a predetermined address in the nonvolatile memory 63. Then, when a new boundary position is detected, it is compared with the previous boundary position,
If there is a difference equal to or greater than the predetermined reference value α, it is determined that an abnormality has been detected. Then, the movement command of the brown rice partition plate 18 is canceled, the brown rice partition plate 18 continues the partitioning operation at the previous partition position, and when the brown rice partition plate 18 is equal to or less than the predetermined reference value α, it is determined that the normal detection is performed. Then, the partition position of the brown rice partition plate 18 is calculated based on the new detection boundary position, and the brown rice partition plate 18 is moved.

With such a configuration, the brown rice partition plate 18
The movement of more than a predetermined distance can be suppressed to prevent the mixing of unpolished rice into brown rice, and the accuracy of brown rice partition plate control can be improved.
In performing automatic partitioning control of the brown rice partition plate 18, the brown rice partition plate 18 is attached to a predetermined relative position with respect to the rice / brown rice discrimination sensor 30, and the rice / brown rice distinction sensor 30 and the brown rice partition plate 18 are integrally moved. It is good also as a structure which performs.
Also, when comparing the previous data with new data,
An average value of a plurality of previous data may be regarded as previous data and compared with newly detected data.

In the above control, for example, the lateral inclination angle of the swing sorting plate 15 and the gap between the hulling rolls are adjusted, and the distribution of the rice and brown rice on the swing sorting plate 15 is controlled. If the selection is changed and the sorting state deteriorates (adjustment of the side inclination, adjustment of the roll gap), the control is stopped in connection with the detection of the adjustment by the sensor. Thus, even if the detection position of the boundary between rice and brown rice changes by the reference value α or more, the partition position of the brown rice partition plate 18 may be calculated and determined, and the brown rice partition plate 18 may be moved.

Next, the embodiment shown in FIGS. 6 and 7 will be described. The paddy / brown rice discrimination sensor 30 is arranged in the supply path from the smashed rice wind selection path 10 and the smashed rice receiving trough 12 to the swing sorting plate 15, and the crushed rice is sampled directly or sampled to reduce the dehulling rate. It is configured to detect, and to input the detection data to the control unit 41. The control unit 41 is connected to a wind control motor 65 via an output circuit. By rotating the wind control motor 65 forward or backward, a wind control valve (not shown) provided on the smashed rice wind selection path 10 is opened and closed to adjust the sorting wind strongly or weakly. .

Next, the control contents of the control unit 41 will be described. During the hulling sorting operation, the data of the hulled / brown rice is detected by the hulled / brown rice discrimination sensor 30, and when the detected data reaches a predetermined number (for example, 2000), the number of grains based on the detected voltage value The standard voltage value part in this distribution map is used as the brown rice distribution part, and the blue rice distribution part, pity distribution part, and paddy distribution part are set sequentially on the higher side (low moisture side) than the brown rice distribution part I do. Then, the number of blue rice grains and the number of pity grains are calculated from the distribution portion.

Next, the number of pity grains and the number of blue rice grains are compared, and when the number of pity grains is large, it is determined that a lot of pity is mixed in the polished rice, and a command to strengthen the sorting wind is output from the control unit 41. And
The wind control motor 65 is rotated forward to adjust the sorting wind to a strong side. Therefore, when the polished rice is selected by the polished rice wind selection path 10, light pity can be removed and labor for pity processing can be omitted.
When the number of pity grains is small, the controller 41 outputs a command to set the selected wind to the standard air volume, and reverses the wind control motor 65 to set the selected wind to the standard air volume. Can be prevented from being discharged outside the machine, and the sorting accuracy can be improved.

FIG. 7 shows a distribution diagram of the detected voltage values, wherein (1) shows a distribution state in which pity is high and blue rice is low.
(2) shows a distribution state with less pity and more blue rice. In controlling the selection air volume, the detected distribution particle number of the pity distribution portion in the distribution map is compared with a reference value, and when the detected distribution particle number is large, pity is determined to be large,
When the number is low, it may be determined that the pity is small, and the sorting wind control may be performed.

Next, an embodiment shown in FIG. 8 will be described. In this embodiment, the paddy / brown rice discrimination sensor 30 detects the loss rate of the smashed rice and, depending on the content of blue rice,
The purpose of the present invention is to improve the accuracy of detecting the loss rate by correcting the determination threshold value of paddy / brown rice. Hereinafter, the control contents will be described. During the hulling sorting operation, the data of the hulled rice is detected by the hulled / brown rice discrimination sensor 30, and when the detected data reaches a predetermined number (for example, 2000), the distribution of the number of grains based on the detected voltage value Create a figure, and set the standard voltage value part in the distribution map as the brown rice distribution part, and sequentially set the blue rice distribution part, pity distribution part, and paddy distribution part on the higher voltage side (low moisture side) than the brown rice distribution part I do. Then, the number of blue rice grains and the number of pity grains are calculated from the distribution portion.

Next, the number of pitiful grains and the number of blue rice grains are compared. If the number of blue rice grains is large, a correction command for the threshold value for discriminating between rice and brown rice is output, and the discrimination threshold value is reduced by a predetermined value to a low voltage value. Side (high moisture side). Therefore, the shedding rate can be calculated by taking into account the amount of blue rice that is largely contained in the grain, and the accuracy of the shedding rate detection is improved. When the number of blue rice grains is small, a threshold correction cancellation command is output to return to the standard threshold value.

The discrimination threshold value for rice / brown rice is calculated, for example, as follows. When detection data of a certain number of grains (for example, 400 grains) of rice and brown rice is obtained by the rice / brown rice discrimination sensor 30, for example, a predetermined voltage value (for example, 0 to 1.9 volts) of the detected voltage value is obtained. The range is brown rice, and the range of a predetermined voltage value (for example, 2.9 to 4.9 volts) is rice. Next, the average rice brown rice voltage (A) and the average rice brown rice voltage (B) are calculated from the detected data and conditions. Next, a predetermined threshold value calculation formula, (BA) / 2 +
A threshold is calculated from A.
