另外，上述品級判別部具備：判別部，其根據上述第一影像處理部、第二影像處理部及第三影像處理部中的各個像素成圖（從各受光單元發送來的受光信號）來判別穀粒的品級。Further, the grade determination unit includes a determination unit that maps (receives signals transmitted from the respective light receiving units) to the respective pixels of the first image processing unit, the second image processing unit, and the third image processing unit.

在上述日本特開2003-42963中記載的穀粒品級判別裝置中，上述光學偵測部的各光學測定部從上述上側照射機構和下側照射機構將光照射到由上述移送部移送的穀粒，並藉由上述各受光單元接收從上述穀粒各個面釋放出的光。In the grain classification device according to the above-described Japanese Patent Application Publication No. 2003-42963, each optical measurement unit of the optical detection unit irradiates light to the valley transferred by the transfer unit from the upper illumination unit and the lower illumination unit. The particles are received by the respective light receiving units to receive light emitted from the respective surfaces of the grains.

上述各受光單元接收到的受光信號被發送給上述品級判別部，該品級判別部的各個影像處理部根據從上述各受光單元發送來的受光信號將上述穀粒表面、側面及背面分別進行像素成圖。The light receiving signals received by the respective light receiving units are transmitted to the quality level determining unit, and each of the image processing units of the quality determining unit performs the grain surface, the side surface, and the back surface based on the light receiving signals transmitted from the respective light receiving units.

因此，即使上述穀粒G的背面側有上述藍色光源32a，上述側面側感測器42的背面用受光區域c仍能夠接收來自上述穀粒G的背面側的藍色光以外的反射光及/或透射光。 [實施例]Therefore, even if the blue light source 32a is provided on the back side of the grain G, the back surface light receiving area c of the side surface side sensor 42 can receive reflected light other than the blue light from the back side of the grain G and/or Or transmitted light. [Examples]

圖4是光學部掃描穀粒的情況的說明圖，是表示藉由受光感測器在移送方向（副掃描方向）掃描穀粒的情況的說明圖。圖5是表示光學部中的光源的點亮和受光感測器的曝光時序圖。4 is an explanatory view showing a state in which the optical portion scans the grain, and is a view showing a state in which the grain is scanned in the transfer direction (sub-scanning direction) by the light receiving sensor. Fig. 5 is a timing chart showing the lighting of the light source and the exposure of the light receiving sensor in the optical portion.

在本發明的穀粒品級判別裝置中，成為品級的判別對象的穀粒G隨著移送部2的圓盤21的旋轉，在收容於上述圓盤21的凹部22的狀態下被連續地向光學部3移送。In the grain type discriminating device of the present invention, the grain G to be determined by the grade is continuously stored in the concave portion 22 of the disk 21 in accordance with the rotation of the disk 21 of the transfer unit 2 Transfer to the optical unit 3.

在上述光學部3中，對被移送到該光學部3的穀粒G照射光，接收來自該穀粒G的反射光及/或透射光並取得受光信號。In the optical unit 3, the grain G transferred to the optical unit 3 is irradiated with light, and reflected light and/or transmitted light from the grain G is received to obtain a light receiving signal.

如圖4所示，在本發明的實施例中，當在表面側感測器41中使穀粒G在該穀粒G的移送方向（副掃描方向）掃描2次期間，在側面側感測器42中掃描一次上述穀粒G。As shown in FIG. 4, in the embodiment of the present invention, when the grain G is scanned twice in the transfer direction (sub-scanning direction) of the grain G in the surface side sensor 41, sensing is performed on the side surface side. The above grain G is scanned once in the unit 42.

具體而言，如圖5所示，在上述光學部3中，表面側光源31和背面側光源32交替反覆點亮和熄滅。並且，表面側感測器41根據配合切換上述表面側光源31和背面側光源32的點亮和熄滅的時序而設定的曝光時間來反覆曝光，在上述表面側感測器41的表面用受光區域a中，在上述表面側光源31的點亮時（第一掃描、第三掃描、……）接收來自上述穀粒G的表面側的反射光，在上述背面側光源32的點亮時（第二掃描、第四掃描、……）接收來自上述穀粒G的表面側的透射光。Specifically, as shown in FIG. 5, in the optical portion 3, the front side light source 31 and the back side light source 32 are alternately turned on and off. Further, the surface side sensor 41 repeatedly exposes the exposure based on the exposure time set by switching the timings of turning on and off the front side light source 31 and the back side light source 32, and the light receiving area on the surface of the surface side sensor 41 is used. In the case where the front side light source 31 is turned on (first scan, third scan, ...), the reflected light from the surface side of the grain G is received, and when the back side light source 32 is turned on (the first The second scan, the fourth scan, ... receive the transmitted light from the surface side of the above-described grain G.

側面側感測器42將上述表面側光源31和背面側光源32連續交替的點亮作為一對，根據配合使上述各光源點亮既定次數（圖5的例子中為各一次）的時序而設定的曝光時間反覆曝光。並且，在上述側面側感測器42的側面用受光區域b中，在上述表面側光源31的點亮時及背面側光源32的點亮時（第一掃描、第二掃描、……）連續接收來自上述穀粒G的側面側的反射光及透射光。另外，在上述側面側感測器42的背面用受光區域c中，在上述表面側光源31的點亮時及背面側光源32的點亮時，經由上述二向性短通濾鏡51連續接收來自上述穀粒G的背面側的反射光及透射光。The side-side sensor 42 alternately illuminates the front-side light source 31 and the back-side light source 32 as a pair, and sets the timings of lighting the respective light sources for a predetermined number of times (one for each time in the example of FIG. 5). The exposure time is repeatedly exposed. Further, in the side light receiving region b of the side surface side sensor 42, the lighting of the front side light source 31 and the lighting of the back side light source 32 (first scanning, second scanning, ...) are continuous. The reflected light and the transmitted light from the side surface side of the grain G are received. Further, in the light-receiving region c for the back surface of the side-side sensor 42, when the front-side light source 31 is turned on and when the back-side light source 32 is turned on, it is continuously received via the dichroic short-pass filter 51. Reflected light and transmitted light from the back side of the grain G.

在本發明的實施例中，設定使得側面側感測器42的曝光時間與表面感測器41不同而較長，因此上述側面側感測器42在側面用受光區域b中接收到中來自上述穀粒G的側面側的受光量增加，上述側面側感測器42的側面用受光區域b從上述穀粒G的側面側接收到的受光信號成為足以用於判別著色粒等的品級的光量。In the embodiment of the present invention, the exposure time of the side side sensor 42 is set to be different from that of the surface sensor 41, and thus the side side sensor 42 is received in the side light receiving area b from the above. The amount of light received by the side surface of the grain G is increased, and the light receiving signal received from the side surface side of the grain G by the light receiving region b of the side surface side sensor 42 becomes a light amount sufficient for determining the grade of the colored grain or the like. .

另外，在本發明的實施例中，將上述表面側光源31和背面側光源32連續交替的點亮作為一對，配合使上述各光源點亮既定次數的時序而設定側面側感測器42的曝光時間，因此上述側面側感測器42的側面用受光區域b從上述穀粒G的側面側接收到的受光信號不偏重於來自上述穀粒G的側面即表面側或背面側位置的反射光及透射光，而包括來自上述穀粒G的側面整體的反射光及透射光。Further, in the embodiment of the present invention, the surface side light source 31 and the back side light source 32 are alternately lit as a pair, and the side surface side sensor 42 is set in accordance with the timing at which the respective light sources are turned on for a predetermined number of times. In the exposure time, the light-receiving signal received from the side surface side of the grain G by the light-receiving area b of the side surface side sensor 42 does not deviate from the reflected light from the side surface side or the back side position of the side surface of the grain G. And transmitted light, including reflected light and transmitted light from the entire side surface of the grain G.

因此，依據本發明的實施例，根據上述側面側感測器42的側面用受光區域b從穀粒G的側面側接收到的受光信號，能夠適當地進行著色粒等的品級判別。Therefore, according to the embodiment of the present invention, the light-receiving signal received from the side surface side of the grain G by the light-receiving region b of the side surface side sensor 42 can appropriately determine the grade of the colored particles or the like.

另外，將上述表面側光源31和背面側光源32連續交替的點亮作為一對，配合使上述各光源點亮既定次數（圖5的例子中各1次）的時序而設定上述側面側感測器42的曝光時間，但是能夠在可以清楚地自上述側面側感測器42的側面用受光區域b從上述穀粒G的側面接收到的受光信號中提取穀粒側面的該穀粒G的特徵的解析度的範圍內，適當地決定上述各光源的點亮次數。 [習知例]In addition, the side surface side light source 31 and the back side light source 32 are alternately lit as a pair, and the side surface side sensing is set in accordance with the timing of lighting the respective light sources for a predetermined number of times (one time in the example of FIG. 5). The exposure time of the device 42, but the feature of extracting the grain G of the grain side from the light receiving signal received from the side surface of the grain G by the light receiving region b from the side surface of the side surface sensor 42 can be clearly seen. Within the range of the resolution, the number of times of lighting of each of the above light sources is appropriately determined. [Prevention example]

圖7是表示光學部掃描穀粒的情況的說明圖。圖7表示光學部中的光源的點亮和受光感測器的曝光的時序圖。FIG. 7 is an explanatory view showing a state in which the optical portion scans the grain. Fig. 7 is a timing chart showing the lighting of the light source and the exposure of the light receiving sensor in the optical portion.

如圖6所示，在習知例中，在表面側感測器41中在該穀粒G的移送方向（副掃描方向）將穀粒進行1次掃描期間，在側面側感測器42中亦將上述穀粒G進行一次掃描。As shown in FIG. 6, in the conventional example, in the side-side sensor 41, the grain is subjected to one scanning in the transfer direction (sub-scanning direction) of the grain G, in the side side sensor 42. The above grain G was also scanned once.

具體而言，如圖7所示，在上述光學部3中，表面側光源31和背面側光源32交替反覆點亮和熄滅。並且，表面側感測器41根據配合切換上述表面側光源31和背面側光源32的點亮和熄滅的時序而設定的曝光時間來反覆曝光，在上述表面側感測器41的表面用受光區域a中，在上述表面側光源31的點亮時（第一掃描、第三掃描、……）接收來自上述穀粒G的表面側的反射光，在上述背面側光源32的點亮時（第二掃描、第四掃描、……）接收來自上述穀粒G的側面側的透射光。Specifically, as shown in FIG. 7, in the optical portion 3, the front side light source 31 and the back side light source 32 are alternately turned on and off. Further, the surface side sensor 41 repeatedly exposes the exposure based on the exposure time set by switching the timings of turning on and off the front side light source 31 and the back side light source 32, and the light receiving area on the surface of the surface side sensor 41 is used. In the case where the front side light source 31 is turned on (first scan, third scan, ...), the reflected light from the surface side of the grain G is received, and when the back side light source 32 is turned on (the first The second scan, the fourth scan, ... receive the transmitted light from the side of the grain G.

側面側感測器42也根據配合切換上述表面側光源31和背面側光源32的點亮和熄滅的時序而設定的曝光時間來反覆曝光。然後，在上述側面側感測器42的側面用受光區域b中，在上述表面側光源31的點亮時（第一掃描、第三掃描、……）接收來自上述穀粒G的側面側的反射光及透射光，在上述背面側光源32的點亮時（第二掃描、第四掃描、……）接收來自上述穀粒G的側面側的反射光及透射光。另外，在上述側面側感測器42的背面用受光區域c中，在上述表面側光源31的點亮時（第一掃描、第三掃描、……）經由上述二向性短通濾鏡51接收來自上述穀粒G的背面側的透射光，在上述背面側光源32的點亮時（第二掃描、第四掃描、……）經由上述二向性短通濾鏡51接收來自上述穀粒G的背面側的反射光。The side-side sensor 42 also repeatedly exposes the exposure time in accordance with the exposure time set to switch the timing of turning on and off the front side light source 31 and the back side light source 32. Then, in the side light receiving region b of the side surface side sensor 42, the side surface side of the grain G is received at the time of lighting (first scanning, third scanning, ...) of the front side light source 31. The reflected light and the transmitted light receive the reflected light and the transmitted light from the side surface side of the grain G at the time of lighting of the back side light source 32 (second scan, fourth scan, ...). Further, in the light-receiving region c for the back surface of the side surface side sensor 42, when the front-side light source 31 is turned on (first scan, third scan, ...), the dichroic short-pass filter 51 is passed through. Receiving transmitted light from the back side of the grain G, and receiving the grain from the grain through the dichroic short-pass filter 51 when the back side light source 32 is turned on (second scan, fourth scan, ...) The reflected light on the back side of G.

在習知例中，將側面側感測器42的曝光時間設為與表面側感測器41相同的長度，因此在上述側面側感測器42的側面用受光區域b中接收到中來自上述穀粒G的受光量變小，上述側面側感測器42的側面用受光區域b從上述穀粒G的側面接收到的受光信號不是足以用於判別著色粒等的品級的光量。In the conventional example, the exposure time of the side-side sensor 42 is set to be the same length as that of the surface-side sensor 41, and thus the side surface of the side-side sensor 42 is received by the light-receiving area b from the above. The light-receiving amount of the grain G is small, and the light-receiving signal received from the side surface of the grain G by the light-receiving area b of the side surface side sensor 42 is not sufficient for determining the grade of the colored grain or the like.

另外，在習知例中，上述側面側感測器42的側面用受光區域b從上述穀粒G的側面接收到的受光信號成為偏重於在表面側光源31點亮時來自穀粒G的表面側、在背面側光源32點亮時來自穀粒G的背面側的反射光及透射光。Further, in the conventional example, the light receiving signal received from the side surface of the grain G by the light receiving region b on the side surface of the side surface side sensor 42 is biased toward the surface from the grain G when the surface side light source 31 is turned on. The side is reflected light and transmitted light from the back side of the grain G when the back side light source 32 is turned on.

因此，若根據習知例，則無法根據上述側面側感測器42的側面用受光區域b從穀粒G的側面側接收到的受光信號，適當地進行著色粒等的品級的判別。Therefore, according to the conventional example, it is not possible to appropriately determine the grade of the colored particles or the like based on the light receiving signal received from the side surface side of the grain G by the light receiving region b of the side surface side sensor 42.

上述本發明的實施形態的穀粒品級判別裝置，是一個光學部3同時接收來自穀粒G的表面、背面及側面的反射光及/或透射光的裝置，但也可以是例如日本特開2003-42963號公報、日本特開2002-20265號公報等所示，由2個光學部分別接收來自例如穀粒G的表面及側面的反射光及/或透射光、來自穀粒G的背面的反射光及/或透射光。In the grain classification device according to the embodiment of the present invention, the optical unit 3 receives the reflected light and/or the transmitted light from the front surface, the back surface, and the side surface of the grain G, but may be, for example, a Japanese special. As shown in Japanese Laid-Open Patent Publication No. 2002-20265, the two optical portions receive reflected light and/or transmitted light from, for example, the surface and the side surface of the grain G, and the back surface of the grain G. Reflected light and / or transmitted light.

另外，即使是如上述本發明的實施形態的穀粒品級判別裝置那樣，由1個光學部3同時接收來自穀粒G的表面、背面及側面的反射光及/或透射光的情況下，在各感測器中分別包括接收來自穀粒側面的反射光及透射光的側面用受光區域b和接收來自穀粒背面側的反射光及/或透射光的背面用受光區域c的情況下，背面用受光區域c與上述表面側感測器41的表面用受光區域a同樣，能夠在背面側光源32的點亮時接收來自穀粒G的背面側的反射光，在表面側光源31的點亮時接收來自上述穀粒G的背面側的透射光。In addition, when the optical unit 3 simultaneously receives reflected light and/or transmitted light from the front surface, the back surface, and the side surface of the grain G, as in the grain type discrimination device according to the embodiment of the present invention, Each of the sensors includes a side light receiving region b that receives reflected light and transmitted light from the side surface of the grain, and a back light receiving region c that receives reflected light and/or transmitted light from the back side of the grain. Similarly to the surface light receiving region a of the front surface side sensor 41, the back light receiving region c can receive the reflected light from the back side of the grain G at the time of lighting the back side light source 32, and the point of the front side light source 31 When it is bright, it receives the transmitted light from the back side of the above-mentioned grain G.

本發明當然不限於上述實施方式，只要不脫離發明範圍即能夠適當變更其結構。The present invention is of course not limited to the above-described embodiments, and the configuration can be appropriately changed without departing from the scope of the invention.
