散して選別するものである。This type of color sorter allows mixed grains containing different colored grains to flow down in a line from a downflow gutter, and a light source and light source are placed around the flow trajectory.
A photoelectric sorting chamber is provided in which a photoelectric detection device consisting of a light-receiving element and a reference color plate and an ejector device consisting of an injection nozzle or an impact piece are arranged in relation to each other. A light source irradiates the object, and a light receiving element detects the difference between the amount of transmitted or reflected light and the amount of light from the reference color plate, and the ejector device is actuated by a control signal from a control circuit that inputs the detection signal. The different colored grains are scattered and sorted.

混入してその精品が品質低下する欠点を有していた。Conventionally known blast type ejector devices usually use a blast of air ejected from the jet nozzle to blow away and sort out different colored grains, but the width of the tip of the blast of air that scatters the grains lacks sharpness. Therefore, since the grains other than the target grains are blown away along with them, there is a drawback that a decline in sorting accuracy is unavoidable.
In addition, the impact ejector device connects the circuit of a sensor that detects different-colored grains with the circuit of a pulse motor to which the impact piece is attached, and instantly collides the sharp solid particles of the impact piece with the different-colored particles to sort them out. This eliminates the problem of expanding the bundle width and separating excessive particles like the air flux of the injection nozzle. The pieces are rotated and stopped when they reach a predetermined position, and during this time, the different-colored grain K11i pieces on the flow trajectory collide to perform a sorting action, and the flow state of each grain in the flow flux is not necessarily changed. When the different colored particles are detected within the operating time of the motor without falling at regular intervals, that is, when 2 to 8 different colored particles flow down in a continuous manner, the 2nd or 8th different colored particles are However, due to the timing being off, the impact action of the impact pieces is not carried out, and different colored grains are often mixed in during sorting and grading, resulting in a deterioration in the quality of the refined product.

んとするものである。In order to solve the above-mentioned drawbacks, the present invention has a circuit of a light receiving element whose optical axis is aligned with the striation of the grain flux, and a plurality of impingement impellers colliding almost perpendicularly to the grain flux. The impellers are arranged in close proximity to each other in a multi-stage manner, and are rotated alternately and in a staggered manner. When 2 to 8 different colored grains flow down in a continuous manner in the trajectory grain flux, each different colored grain is reliably and easily sorted by multiple impact impellers that operate in a timely manner. In this way, we aim to develop and provide a device that completely eliminates different colored particles in the flux and always exhibits a highly accurate detection function.
