Description of the Invention (1) Background of the Invention and Related Techniques The present invention relates to a grain color sorting device that optically detects grains such as rice, wheat or beans Foreign body or undesirable grain, so as to classify or distinguish and attach it. In this article, the * color * of the granular object means "" Yi granule color #. As long as there is no other requirement, the granular object | transparent" means "transparent to visible light", that is, * has the property of transmitting visible light ^. As disclosed in Japanese Patent Unexamined Publication No. 1 2 5 8 7 8 1, in traditional color classification devices, the grains are irradiated with light sources such as incandescent lamps, fluorescent lamps, etc. in the visible light area, which are dedicated to a plurality of visible light areas. The light receiving element of the wavelength band detects the difference between the light intensity from the grain irradiated by the light source and the light intensity from the background as a reference color plate, so as to use the color difference between the good grain and the foreign body to identify and remove the foreign body. However, in the above-mentioned conventional color sorting device, if the foreign matters mixed in the grains such as broken glass, plastic, gold tulle, pottery, porcelain, etc. have the same color as the good grains or are transparent, the foreign matters cannot be properly separated and removed. Japanese Patent Unexamined Announcement No. 5-2 0 0 3 6 No. 5 discloses a foreign object detection device, in which near-infrared light illuminates the inspection area, and from the light scattered and penetrated by the object to be inspected, the near-infrared light area (in the 7 5 0 ~ 2 5 0 0 nm wavelength) light of two specific wavelengths (about 1 3 0 0 nm and about 1 4 6 0 nm), the two detected values are compared with the predetermined values to determine the inspection The object is a desired object such as white rice grain or a foreign object such as a glass sheet or a plastic sheet, in order to detect and distinguish good grains from foreign objects having the same color or transparency.

Description of the invention (2) However, the near-infrared light area is only used as the light source with the above foreign object detection device Undesirable grains, etc. are separated from good grains. Therefore, in order to identify and remove bad grains, etc., it is necessary to additionally provide a traditional color sorting device that uses a visible light area as a light source. That is, the general foreign objects that are different in color from the good grains are first distinguished from the good grains in the visible light region by the traditional color sorting device, and thereafter, the foreign body detection device using near-infrared light is used to distinguish and remove the good grains Other isomers of the same color or transparent as good grains. On the other hand, the use of infrared light as a light source disclosed in Japanese Patent Unexamined Publication No. 5-2 0 0 3 6 5 incorporating a foreign object detection device into a conventional color classification device that uses light in the visible region makes the device too complicated And increase the size, resulting in too troublesome device maintenance Summary of the invention In view of the above problems, the object of the present invention is to provide a grain color sorting device, a color sorting device that can be detected in the visible light 13E to distinguish from good grain and exclude and good determination Foreign objects with different colors can be detected on the near infrared light surface to distinguish and remove other foreign objects with the same color as the good grains or transparent in the visible light region, such as glass sheets, plastic sheets, etc., from good grains. According to the present invention, the grain color classification device achieves the above objectives, including: a grain guide device that guides the grain to a predetermined detection position along a predetermined grain flow path: a yin device, which feeds the grain to the guide valley Light detection device, including an irradiation device that irradiates grains flowing down a predetermined detection position along a flow path, a light-receiving sensor device that receives light intensity from the irradiated grains, and the light-receiving device that opposes the grain Background device with flow path in between This paper scale is applicable to the national standard (CNS) A4 specification (2I0X297 mm)

If the light intensity reflected from the background opposite to the first light receiving sensor portion is adjusted in advance, Consistent with the light intensity from the desired good grains (such as white rice), even if the good grains pass through the detection position, the light intensity received by the first light receiving sensor section (via the filter) and the first light receiving The output signal of the sensor unit also does not change. However, when granular stirrups or foreign objects different in color from the good grain pass through the detection position, the received light intensity and output signal change, so the ejector is operated in response to the output signal Device, different colors The granular objects or foreign objects are led to other flow paths. Even if the light intensity received by the first light-receiving sensor portion and its output signal are approximately unchanged, good grains may be mixed with foreign objects of the same color or transparent (such as broken glass pieces) , Plastic, metal, pottery, porcelain, etc.). Good grains (such as good white rice grains) absorb near-infrared light, so the reflectance in the near-infrared region is low. But such as broken glass, plastic, metal, porcelain, etc. The foreign matter does not absorb near-infrared light, so the reflectance in the near-infrared light region is high.

The description of the invention (5) is basically unchanged, even if When the good grain (white rice) passes the detection position, the light intensity received by the second light-receiving sensor part and its output signal are also substantially unchanged. However, when the foreign body is the same color or transparent as the good grain When the position is detected, the foreign object is reflected back and the light intensity received by the second light-receiving sensor section changes, so the output signal of the second light-receiving sensor section changes. In response to the second light-receiving sensor section The output signal of the product changes, and the operation introduces foreign objects of the same color or transparent as the good grains to other flow path ejector devices to identify and remove the foreign bodies. Then, good grains such as white rice grains (even by detecting the position, do not cause The light intensity received by the first and second light-receiving sensor parts and the change of its output signal) are transferred to a receiving tank that receives good grains, and are discharged into products by an appropriate conveying device.

Description of invention (8) Detection and identification (selection) The reflectance characteristics of grains and foreign objects of objects. Good grains are different from bad grains or foreign objects of different colors (in visible light BE), and of course the reflectance characteristics (wavelength dependence of reflectance) in the visible light region are different. On the other hand, as shown in Fig. 4, there is no big difference between grains such as good rice grains and foreign substances such as white stones and glass flakes and transparent glass flakes in the same color of visible light E, but in about 1 4 0 0 ~ 1 6 0 0 The reflectance characteristics of the near-infrared region in the nm wavelength band vary greatly. That is, as can be seen from Q4, in the wavelength band of approximately 1 400 to 160 nm in the near infrared region, the reflectance of white rice grains is low, but the reflection of foreign objects may be relatively high. The light detection section 6 of the light detection device will be described with reference to FIG. 2. The light detection section 6 includes a light detection box 14 that fixes the silicon photoreceptor 13 of the first light receiving sensor section, and a light detection box that fixes the germanium photoreceptor 15 of the second light receiving sensor section 1 6. A silicon photoreceptor 13 with a lens barrel 17 is inserted and installed in the light detection box 14.

Description of the invention (9), the lens barrel 21 is provided with permission Filter 2 1 a for light penetration in the near infrared region. For the visible light penetrating the illuminator 1 7 a, in order to distinguish the color of the grain between black and white only by the visible light, this filter is appropriately selected to allow light transmission in the wavelength band of 4 2 0 ~ 4 9 0 nm as shown in Figure 3. Hatching. On the other hand, for near-infrared light penetrating the filter 2 1 a, in order to distinguish foreign substances that are difficult to distinguish in the visible light region from good grains, this filter is appropriately selected to allow a wavelength of 1 4 0 0 ~ 1 6 0 0 nm The light of the belt penetrates the hatched line shown in Figure 3. It can be seen from Pr4 that in the wavelength range of 1 4 0 0 ~ 1 6 0 Onm, the reflectance of white rice grains is very different from that of white stones, plastic sheets, and transparent glass sheets, so white rice grains can be distinguished from these foreign objects. The background 24 is located at the light detection box 16 to face the silicon photoreceptor 13 with the detection position F interposed therebetween, and is made of a glass plate with a white surface. Scattered reflection or transmission of light can be applied. The fluorescent lamp 2 2 is located near the background 24 and constantly illuminates the background 24. The servo motor (not shown) changes the rotation angle around the axis 2 4 a or the tilt angle with respect to the fluorescent lamp 2 2 to change the light intensity received from the fluorescent lamp 2 2. Similarly, the background 20 is located in the light detection box 14 to face the germanium photoreceptor 15 with the detection position F between them, and is made of a glass plate with a white surface and so on. Scattered reflection or transmission of light can be applied. The _lamp 19 is located near the background 20 and constantly illuminates the background 20. The rotation angle around the axis 20 a or the inclination angle with respect to the halogen lamp 19 is changed to change the light intensity received from the halogen lamp 19. The surfaces of the light detection boxes 14 and 16 facing each other are formed by transparent glass plates 25 and 26, respectively, to prevent dust and the like from entering the boxes 4, 16.

Fig. 6 shows the waveforms of the output signals S I, SV and S of the photoreceptors 15, 13 and the signal processor 27. When the good grains (good white rice grains) pass the detection bit SF, the output signal SV of the silicon photoreceptor 13 changes a little, but when the granular objects to be separated or removed (can be discerned by the light in the visible light region, such as colored grains) , Black stones, etc.) changed a lot when it passed. Therefore, based on the output signal SV of the silicon photoreceptor 13 and the brightness difference of the visible light M, good grains (good white rice grains) can be detected and distinguished from foreign objects such as colored grains, black stones, etc. Even if the signal SV of the silicon photoreceptor 13 does not change, good grains may be mixed with foreign substances of the same color or transparent (such as white stones, glass flakes, plastic flakes, etc.). The germanium photoreceptor 15 constantly monitors the background 20 pre-adjusted the rotation angle around the axis 20 a to have the same brightness as the good grain (white rice) in the near infrared light region. When the good grains (good white rice grains) pass the detection position F, the output signal SI of the germanium photoreceptor 15 changes a little, but when the granular objects to be separated or removed (can be distinguished in the near infrared light region, such as glass sheets, Plastic pieces, white stones, etc.) change a lot when they pass. Therefore, the output signal SI of the germanium photoreceptor 15 can detect and distinguish good grains (good white rice grains) from foreign objects such as glass sheets, plastic sheets, etc. based on the difference in brightness of the near infrared light (see Figure 6) .
