Abstract

PURPOSE:To improve screening efficiency by providing a television camera which picks up the front surface of a screening plate, an image processing means, an inclination driving means which controls the inclination angle of the screening plate to the above device. CONSTITUTION:The television camera 11 is so positioned that the areas X1 to X3 of the areas X1 to X6 dividing the image pickup range 14 of the television camera 11 in the transverse direction of the screening plate 1 detect a mixed rice layer A2, and X4 to X6 detect an unpolished rice layer A3 at the time of starting the screening operation. The inclination driving means 3 is instructed to decrease the inclination of the screening plate 1 and to control a boundary line B2 so as to return to the center of the image pickup range when an image processing means 12 detects the deviation from the center of the image pickup range. A limit detection signal which indicates that the inclination of the screening 1 attains the state of an upper or lower limit is inputted form the inclination driving means 3 to the image processing means 12. The processing capacity is greatly improved in this way.

The sorting plate 1 is supported via a rolling drive means 3 and a vibration device 2. When the mixed rice 5 is supplied to the upper end 4 of the sorting plate 1, the mixed rice 5 is transferred to the sorting plate 1 by the friction and vibration of the sorting plate 1.
It is transferred toward the 0th end 6. During this transfer, a flow distribution of the paddy layer M, mixed rice NJA2, and brown rice MA3 occurs on the upper surface of the sorting plate 1, as shown in FIG. B
1 is the boundary between the m layer A1 and the mixed rice layer g, and B2 is the boundary between the mixed rice layer and the brown rice mA3. Lower end 6 of sorting plate 1
The first section is movable in the width direction. A second partition plate 7.8 is provided, and the partition plate 7 @1 is connected to the boundary line B1.8. The second rice grain layer 8 is positioned corresponding to the boundary line B2. A photoelectric sensor 9 is attached to the second partition plate 8, which detects the position of the boundary line B2 by utilizing the difference in light reflectance between the mixed rice layer and the brown rice layer M, and detects the position of the boundary line B2. The partition plate driving means 1 is moved so that the position of
0 control, the position of the partition plate 8 is changed.

Problems to be Solved by the Invention In such a conventional configuration, the position of the partition plate 8 is changed based on the signal from the photoelectric sensor 9, and only brown rice is sorted from the fixed area C divided by the partition plate 8. However, since the detection area by the photoelectric sensor 9 is a spot, the response is slow and the accuracy is low when controlling the position of the partition plate 8 and the boundary line B2. Therefore, the partition plate 8 is set on the safe side so as to be located inside the brown rice mA3 from the position of the actual boundary line B2 to prevent mixed rice from getting mixed into the sorted and fixed brown rice. Since it is necessary to set it on the safe side in this way, the amount of brown rice that can be taken out by sorting is reduced, and the processing capacity is low.
