This optical sorting device is provided with a chute which has an optical detection slit and a sorting removal slit disposed downstream of the optical detection slit, and down the top surface of which objects to be sorted flow, wherein: a rear-side illuminating unit of an optical inspecting unit, and an ejector nozzle are attached to a rear-side housing; and the rear-side housing is installed on the back surface side of the chute in such a way that the rear-side illuminating unit faces the optical detection slit, and the distal end of the ejector nozzle faces the sorting removal slit.
Provided is a grain gloss measurement apparatus capable of accurately measuring gloss of grain. A grain gloss measurement apparatus includes a light source to emit light to a measurement region for grain in an oblique direction, a light receiver to receive the light reflected from the measurement region, and a gloss value calculation device to calculate a gloss value of the grain based on the reflected light received by the light receiver. The light source includes a first light source to emit light to the measurement region from one side and a second light source to emit light from another side that is opposite to the first light source across the measurement region. The light emitted from the first light source and the light emitted from the second light source have different wavelengths. The light receiver is disposed on the same side as the second light source, and the gloss value calculation device includes an image processing unit to identify a grain zone in the measurement region based on the light of the second light source that is reflected off the grain and received by the light receiver.
Provided is a method for detecting an object to be sorted, in an optical sorting device that can detect a side portion of a planar object to be sorted. The present invention is characterized in that: the chute is provided with a plurality of parallel longitudinal grooves formed in the longitudinal direction by a plurality of protruding walls; and a planar object to be sorted is made to flow down on the surface of the chute while a substantially flat surface of the planar object abuts the protruding walls to orient a side portion thereof in the front-rear direction of the chute, so that an optical detection unit can detect, at a detection position, the side portion of the object to be sorted. The planar object to be sorted is a rice grain, and it is preferable that the optical detection unit detects, at a detection position, the rice bran that remains on the spine of the rice grain.
This optical sorting machine is provided with a first light source disposed on a first side, a second light source disposed on a second side, an optical sensor configured to detect light in a plurality of scanning periods including a first scanning period and a second scanning period, a determination unit configured to make a determination of foreign matter and/or a defective product, and a light source control unit. The light source control unit is configured to control the first light source and the second light source such that lighting in the first scanning period has a first lighting pattern that is a lighting pattern freely selected from among a lighting pattern in which the first light source and the second light source are on, a lighting pattern in which only one of the first light source and the second light source is on, and a lighting pattern in which only the other of the first light source and the second light source is on, and that lighting in the second scanning period has a second lighting pattern that is a lighting pattern freely selected from among the lighting patterns other than the first lighting pattern.
