이하 참조 도면을 참조하여 본 발명을 보다 상세히 설명하고자 한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명에 의한 색채선별기를 나타내는 단면도이다.1 is a cross-sectional view showing a color sorter according to the present invention.

도 1을 참조하면, 색채선별기(100)은 상층부에 입상물질을 담는 호-퍼(1)가 있고, 그 밑에는 피-다(feeder)(2)가 있어 도 3에서 나타난 것과 같이 입상물질이 활강사면로(4)로 잘 퍼져서 내려가게하고 그 구조는 앞단이 경사지고 V자 혹은 U자 형의 가이드홈(27)이 있고 이 가이드홈(27) 골은 활강사면로(4) 각 채널(Channel)의 골과 일치되게 하여 입상물질을 골고루, 정확하게 활강사면로(4)로 넣어주는 역할을 하고 그 밑에는 진동소자(3)가 있다. 그리고 그 진동부(2) 아래에는 여러 개의 채널(Channel)이 형성되어 있고 각 채널단면은 밑면이 각진 U자형 혹은 V자형으로 된 활강사면로(4)가 있다.Referring to Figure 1, the color sorter 100 has a hopper (1) containing the granular material in the upper layer, there is a feeder (2) under the granular material as shown in Figure 3 It spreads well down the slope slope (4), and its structure is inclined at the front end and has a V-shaped or U-shaped guide groove (27), and the goal of the guide groove (27) is the slope slope (4) for each channel ( Channel) is consistent with the goal of the granular material, evenly, and puts into the sliding slope (4), and there is a vibrating element (3) below. Under the vibrator 2, a plurality of channels are formed, and each channel section has a sliding slope 4 having a U-shaped or V-shaped angled bottom.

종전에는 대기 환경 온도,습도 특히 습도가 많은 환경에서 활강사면로(4)에 대기 중에 있는 수분이 고착되어 먼지로 인한 오염이 쉽게 발생되어 입상물질의 하강속도에도 영향을 주게되고 품질문제를 유발시키는데 이를 해결하기 위하여 항상 일정한 활강사면로(4)조건을 유지하여야 하며 이를 위하여 온도 제어가 가능한 히-터(5)를 활강사면로(4) 배면에 부착하도록 하여 각 채널(Channel)을 건조시켜 수분과 먼지가 고착되지 못하게 하였으며 입상물질은 또한 활강사면로 모양에 따라 유동저항이 변하게 할 수 있기 때문에 현재의 각진사각형(41) 혹은 V자형(42)에서 도 5와 같이 밑이 둥근 U자형(43)으로하여 정속도를 최대한 유지하게 하고 있다.Previously, moisture in the air adhered to the sliding slope 4 in the environment of air temperature, humidity, and especially high humidity, and pollution caused by dust is easily generated, which affects the descending speed of granular materials and causes quality problems. In order to solve this problem, it is necessary to maintain a constant sliding slope (4) condition at all times. To this end, a heater (5) capable of temperature control is attached to the rear surface of the sliding slope (4) to dry each channel. And the particulate matter can also change the flow resistance depending on the shape of the sliding slope, so that the current U-shaped (43) rounded bottom as shown in Fig. 5 in the square (41) or V-shaped (42) ) To maintain the constant speed as much as possible.

도 2에서 상기 검출부(7)는 광원(21), 보호렌즈(13), 집광을 잘 해주기 위한 복수 개의 광학렌즈(17), 슬롯판(18), 센서(28), 그리고 증폭부(20)으로 구성되어 있고, 센싱하는 방법은 광원(21)에서 입광된 입상물질의 반사광과 투과광은 보호렌즈(13), 복수개의 집광렌즈(17)를 통하게 하고 공기분사노즐구멍과 비례되는 슬롯(18')크기를 만들어 주고 나머지는 필터링되게 하여 특정한 부분(Area)만 센서(28)로 집광되게 하고 집광된 미세한 신호를 증폭부(20)에서 몇 단계 증폭하게하여 양품, 불량품을 선별토록한 원리로서 이감광기(101)은 매우 민감한 부분이기 때문에 감광기(101)을 먼지나 이물질로부터 보호하는 것은 매우 중요하다. 이를 위하여 보호 및 먼지방지용 투명판(14)과 케이스(16)를 틈이 없도록 밀폐시키고 접착제로 코-팅을 한 후 또한 앞, 뒤 검출부(7) 케이스(16)에 공기투입구(25)와 에어샤-워시스템(Air Shower System)(24)를 설치해 줌으로서 먼지나 이물질이 투명판(14)에 고착되지 못하게 하고 이어 검출부(7) 주위 전역을 집진시킬 수 있도록 집진장치(102)를 설치한다.In FIG. 2, the detection unit 7 includes a light source 21, a protective lens 13, a plurality of optical lenses 17, a slot plate 18, a sensor 28, and an amplifying unit 20 for condensing well. In the sensing method, the reflected light and the transmitted light of the granular material received from the light source 21 are passed through the protective lens 13 and the plurality of condenser lenses 17 and are slots 18 'proportional to the air ejection nozzle holes. ) Make the size and filter the rest so that only a specific area is collected by the sensor 28, and the condensed minute signal is amplified by the amplifier 20 by a few steps. Since the madness 101 is a very sensitive part, it is very important to protect the photosensitive member 101 from dust and foreign matter. For this purpose, the transparent plate 14 and the case 16 for protection and dust prevention are sealed so that there is no gap, and after coating with an adhesive, the air inlet 25 and the air are inserted into the case 16 of the front and rear detectors 7. By installing a shower system (Air Shower System) (24) to prevent dust or foreign matter adhered to the transparent plate 14, and then to install a dust collector 102 to collect the entire area around the detection unit (7) .

이때 정확한 검출을 위하여 입상물질의 양품색과 같은 색의 기준색으로 반사판(15)를 앞,뒤 검출부(7)의 감광기 밑에 만들어 주어 감광기(7)가 맞은 편 반사판과 일직선 상에서 바라보게하여 앞.뒤 감광기(7)는 입상물질 앞.뒤로 검사할 수 있는 도 1의 공통점(6)에 서로 바라볼 수 있는 위치에 두어 불량품이 왔을 때 선명하게 불량을 감지할 수 있도록 하는 역할을 할 수 있도록 한다. 또한 감광기(101)에서 선별된 불량품은 그 신호가 이젝터(8)에 전달이 되어 순간적으로 공기를 분사하여 불량품을 불량수거출구(11)로 보내도록 해야하는데 입상물질이 떨어지는 낙하속도는 초당 수백개로 초고속인데 현재 주로 원형으로 이루어져 있는 공기분사노즐을 사용함에 따라 넓은 공간을 공기가 분사하여 양품손실이 많아지고 정확도도 떨어지는 문제가 있다. 본 발명은 이를 해결하기 위하여 도 4에서 원형 대신 슬롯형의 노즐구멍을 사용하여 정확도를 높였으며 슬롯(19)의 크기는 감광기(101)의 슬롯(18') 크기와 비례하여 적당한 크기를 만들었다. 이젝터(8)구성은 제 4 도에 나타나 있으며 상술하면 사각의 금속통(29)에 내부구멍(31)을 길게 관통시켜 좌,우선단은 콤프레샤호-스와 연결토록하여 항상 전압의 공기가 채워지고 단지 불량감지 신호가 솔레로이드밸브(30)로 전달될 대 공기가 초고속으로 분사 작동토록하여 색채선별기의 정확도를 높이고 생산성을 향상시켰으며 도 1에서 나타난 바와 같이 이젝터(8)가 공기를 고압으로 분사시 고압의 공기가 검출부(7)외부의 공기 흐름을 방해하고 분진 발생시키는 문제가 있는데 이을 최소화 시킬 목적으로 검출부(7)와 이젝터(8) 간에는 분리벽(9)이 설치되어 있다.At this time, for accurate detection, the reflecting plate 15 is made under the photosensitive members of the front and rear detecting unit 7 with the reference color of the same color as the good color of the granular material so that the photosensitive member 7 faces in a straight line with the opposite reflecting plate. The front and rear photoreceptors (7) are placed in a position where one can look at each other at the common point (6) of FIG. 1, which can inspect the particulate material front and back, and serves to clearly detect the defect when the defective article comes. To be able. In addition, the defective product sorted by the photoreceptor 101 should be sent to the ejector 8, the signal is instantaneously injected to send the defective product to the defective collection outlet 11, the falling rate of falling granular material is several hundred per second It is an ultra-high speed dog, but as the air spray nozzle is mainly composed of circular air, the air is sprayed over a large space, resulting in a large amount of loss of product and a decrease in accuracy. In order to solve this problem, the present invention improves accuracy by using a slotted nozzle hole instead of a circular shape in FIG. 4, and the size of the slot 19 is appropriately proportional to the size of the slot 18 ′ of the photoreceptor 101. . The configuration of the ejector 8 is shown in FIG. 4. In detail, the ejector 8 has a long through-hole 31 penetrating the rectangular metal barrel 29 so that the left and right ends are connected to the compressor hose so that the air of voltage is always filled. Only when the bad detection signal is transmitted to the solenoid valve 30, the air is sprayed at a very high speed to increase the accuracy of the color sorter and improve the productivity. As shown in FIG. 1, the ejector 8 injects the air at a high pressure. When the high-pressure air hinders the air flow outside the detector 7 and generates dust, a separation wall 9 is installed between the detector 7 and the ejector 8 for the purpose of minimizing the dust.
