ために、数十種類に塗り分けた基準色板をその都度選択

基準色板の光量を増減させて調節するという技術である
。By the way, reference color plate adjustment involves selecting and replacing dozens of different types of reference color plates each time in order to match the hue and brightness of the reference color plate to those of the particles based on the raw material particles to be color sorted. Alternatively, it is a technique in which the light intensity of a reference color plate is increased or decreased by increasing or decreasing the light intensity of one color lamp.

ものであった。In the case where the reference color plate is adjusted by increasing or decreasing the light intensity of the lamp, the adjustment is done only for one lamp, and cannot be adjusted individually for the light-receiving elements via two optical filters with different wavelengths. Therefore, there are many raw material particles that cannot be adjusted to an appropriate reference color plate, and there is a problem in that the screening performance of all particles cannot be completely satisfied.

は同じく赤色フィルターを介して受光素子により受領さ

く緑色フィルターを介して受光素子に受領される。The particles transferred to the detection position are illuminated, and the amount of reflected light and the amount of transmitted light from the particles are respectively communicated to a light receiving element via two optical filters with different wavelengths. Light 1 will also be contacted. Referring to FIG. 7, for example, the reference color plate adjustment means has two lamps connected through a red filter (main wavelength: 670 nll, reference numeral C in the figure) and a green filter (main wavelength 550 nil, reference numeral in the figure). However, the light intensity of each lamp is adjusted by adjusting the supply voltage. The amount of light from the lamp that has passed through the red filter is received by the light receiving element via the red filter, and the amount of light from the lamp that has passed through the green filter is also received by the light receiving element via the green filter.

変化するので、異色粒を別の流路に誘導する選別手段が
作動する。同様に緑色フィルターを介したランプの光量
も標準色粒子の光量と一致するように調節される。The amount of light received by the light receiving element through the red filter of the particles illuminated by the illumination means is compared with the amount of light from the lamp through the red filter, so the amount of light from the desired standard color particles and the lamp through the red filter are compared. If the optics are adjusted so that they match, even if standard color particles pass through, there will be no change in the light reception signal at the light receiving element through the red filter, but when different color particles pass through the detection position, the light reception signal will change. Therefore, the sorting means for guiding the different-colored grains to another channel is activated. Similarly, the amount of light from the lamp that passes through the green filter is adjusted to match the amount of light from the standard color particles.

ができる。At the start of operation, the grains transferred to the detection position are compared with the lamp voltage initially set in several stages depending on the type of grain and the reference color plate grain. In some cases, the reference color adjustment is not performed, so the discharge valve provided in the discharge pipe 17 is closed and all the grains are returned to the raw material side via the collection 8I27.When the reference color adjustment is completed, the discharge valve 17A is closed. The injection valve 25 is opened to detect only the different colored particles, and the injection valve 25 is activated to open the injection nozzle 26.
Compressed air can be ejected from the tube to guide the different colored particles to the collection gutter.
基準色板調節作用は次の手順で順次進行する。The reference color plate adjustment operation proceeds sequentially in the following steps.

Next, the respective light reception signals of each light receiving element when the voltage of the red and green reference lamps 38.40 is lowered by a certain amount (for example, O, 2 volts) are input into the microcomputer circuit in the same way, and are stored first. The optimum voltage value is set based on the comparison value.

At the same time, the reference color can be completely adjusted in the same wavelength range for each light receiving element, which cannot be adjusted with a single lamp, and it can be automated, making it accurate and unmanned operation possible. It is something to do.
