색채선별기{Color Sortor}Color sorter

본 발명은 색채선별기에 관한 것으로, 더욱 상세하게는 가이드홈(Guide 홈)이 형성된 피-더(Feeder)와, 활강사면로 뒷면에 히-터(Heater)가 부착된 밑이 둥근 U자형 채널을 가진 활강사면로와, 검출부 투명판 소제를 위하여 에어 샤-워시스템(Air Shower System)과 불량품을 정확히 불어주기 위하여 슬롯(Slot)형 공기분사노즐 이젝터(Ejector)가 구비된 구조로 되어 있는 색채선별기에 관한 것이다.The present invention relates to a color sorter, and more particularly, a feeder having a guide groove and a bottom U-shaped channel having a heater attached to the back of a sliding slope. The color sorting machine is equipped with a sliding type slope and an air shower system for ejecting the transparent plate of the detector and a slot-type air injection nozzle ejector to blow the defective parts accurately. It is about.

최근까지 주종을 이루는 색채선별기는 광의로는 어느 입자상의 물질을 그 색깔에 따라 다른 특정한 입상(粒狀)물질들로부터 분리시키는 것으로서 그 대상물로는 입상물질로 곡물류, 플라스틱 팰렛(Pellet), 의약품의 알약 등 다양한 종류의 색채선별에 사용하고 있다.Until recently, color sorters, which predominantly predominantly separate particles from a particular granular material depending on their color, are the granular materials of grains, plastic pallets and pharmaceuticals. It is used for various kinds of color screening such as pills.

이러한 종래의 색채선별기는 항상 일정한 작업분위기가 구현되지 못하여 입상물질을 피-더(Feeder)에서 활강사면로로 골고루 분산하여 투입하기가 어렵고, 대기 중의 습도 상태나 온도 변수가 따라 활강사면로의 조건이 달라져 입상물질의 낙하속도에 변화를 주는 경우가 있었다. 검출부 투명판은 쌀겨, 먼지나 기타 이물질로 인하여 오염되기 쉬웠다. 활강사면로의 모양도 각진 사각형이나 브이(V)자형이 주종을 이루고 있었으며, 또한 이젝터(Ejector)의 공기구멍이 원형임에 따라 넓은 부분을 분사해 줌으로써(즉, 분사 범위가 넓어서) 선별정확도가 떨어져 양품조차 불량품과 같이 불어 주어 불량 처리하는 문제가 있다.Such a conventional color sorter does not always implement a constant working environment, so it is difficult to disperse granular materials evenly from the feeder to the sliding slope, and the conditions of the sliding slope according to the humidity conditions or temperature variables in the atmosphere This may change the drop rate of the particulate matter. The transparent plate of the detector was easily contaminated by rice bran, dust or other foreign matter. The shape of the downhill slope is mainly composed of an angled square or a V-shape. Also, as the air hole of the ejector is circular, a large part is sprayed (that is, the spraying range is wide) so that the accuracy of the selection is high. Even good quality blows away with defective goods, there is a problem of poor handling.

따라서, 본 발명의 목적은 고품질과 양산성이 우수한 색채선별기 구조에 관한 것이다.Accordingly, an object of the present invention relates to a color sorter structure having high quality and excellent mass productivity.

이하 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. 도 1을 참조하면, 색채선별기(100)는 상층부에 입상물질을 담는 호-퍼(1)가 있고, 그 밑에는 피-다(Feeder)(2)가 있다. 피다(feeder)(2)는 도 3에 나타난 것과 같이 입상물질이 활강사면로(4)로 잘 퍼져서 내려가도록, 그 구조는 앞단이 경사져 있고, V자 혹은 U자형의 가이드홈(17)이 있다. (도 3의 위 도면 참조) 이 가이드홈(17)의 골은 활강사면로(4)의 각 채널(Channel)의 골과 일치되게 하여 입상물질을 골고루, 정확하게 활강사면로(4)로 넣어주는 역할을 한다. 피다(2)의 밑에는 진동소자(3)가 있다. 그리고 그 피다(2)의 아래에는 여러 개의 채널(Channel)이 형성되어 있고 각 채널단면은 밑면이 각진 U자형 혹을 V자형으로 된 활강사면로(4)가 있다. 종전에는 대기 환경 온도, 습도 특히 습도가 높은(즉, 습기가 많은) 환경에서 활강사면로(4)에는 대기 중에 있는 수분이 고착되어 먼지로 인한 오염이 쉽게 발생되어 입상물질의 하강속도에도 영향을 주게되고 품질문제를 유발시켰다. 이를 해결하기 위하여 항상 일정한 활강사면로(4)조건을 유지하여야 하는데, 이를 위하여 온도제어가 가능한 히-터(5)를 활강사면로(4) 배면에 부착하도록 하여 각 채널(Channel)을 건조시켜 수분과 먼지가 고착되지 못하게 하였다. 입상물질은 또한 활강사면로 모양에 따라 유동저항이 변할 수 있기 때문에 종래의 각진 사각형(41)(도 5 참조) 혹은 V자형(42)(도 5 참조)에서 도 5와 같이 밑이 둥근 U자형(43)으로 하여 정속도를 최대한 유지하게 하고 있다.1 is a cross-sectional view showing a color sorter according to the present invention. Referring to FIG. 1, the color sorter 100 has a hopper 1 containing a granular material at an upper layer thereof, and a feeder 2 below the pulverizer. The feeder 2 has an inclined front end and has a V-shaped or U-shaped guide groove 17 so that the granular material spreads well down the sliding slope 4 as shown in FIG. . (See the top view of Figure 3) The groove of the guide groove 17 is equal to the goal of each channel (Channel) of the sliding slopes (4) to put the granular material evenly, accurately put into the sliding slopes (4) Play a role. There is a vibrating element (3) under the pidda (2). Under the fender 2, several channels are formed, and each channel section has a sliding slope 4 having a U-shaped or V-shaped angled bottom. Previously, in the environment of atmospheric temperature, humidity, especially high humidity (ie, high humidity), the sliding slopes 4 adhered to moisture in the air, causing contamination by dust, which affects the descending speed of particulate matter. And caused 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. Moisture and dirt were prevented from sticking. Since the granular material can also change the flow resistance according to the shape of the sliding slope, the U-shaped rounded bottom as shown in Fig. 5 in the conventional angled square 41 (see Fig. 5) or V-shape 42 (see Fig. 5). It is set to (43) to maintain a fixed speed as much as possible.

도 2를 참조하면, 상기 검출부(7)는 광원(21), 보호렌즈(13), 집광을 잘 해주기 위한 복수 개의 광학렌즈(17), 슬롯판(18), 센서(28), 그리고 증폭부(20)로 구성되어 있다. 센싱하는 방법은 감광기(101)로 입광되는 입상물질의 반사광과 투과광은 보호렌즈(13), 복수개의 집광렌즈(17)를 통하게 되고, 후술하는 공기분사노즐구멍과 비례하는 크기의 슬롯(18`)을 가진 슬롯판(18)에서 나머지는 필터링되게 하여 특정한 부분(Area)만 센서(28)로 집광되게 하고 집광된 미세한 신호를 증폭부(20)에서 몇 단계 증폭하여 양품, 불량품을 선별토록 한 원리이다. 이감광기(101)는 매우 민감한 부분이기 때문에 감광기(101)를 먼지나 이물질로부터 보호하는 것은 매우 중요하다. 이를 위하여 보호 및 먼지방지용 투명판(14)과 케이스(16)를 틈이 없도록 밀폐시키고 접착제로 코-팅을 한다. 또한 검출부(7) 케이스(16)에 공기투입구(25)와 에어샤-워시스템(Air Shower System)(24)을 설치해 줌으로써 먼지나 이물질이 투명판(14)에 고착되지 못하게 한다. 이 에어샤워시스템은 정기적으로 선별 작업을 중단하고 검출부를 소제할 때에도 사용할 수 있다. 공기를 불어주면서 브러쉬(Brush)가 붙어 있는 와이퍼(Wiper)로 좌.우 왕복하게 하여 투명판을 청소하면 효과적으로 소제할 수 있다.Referring to 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 for condensing well. It consists of 20. In the sensing method, the reflected light and the transmitted light of the granular material incident to the photosensitive device 101 pass through the protective lens 13 and the plurality of condensing lenses 17, and the slot 18 having a size proportional to the air spray nozzle hole described later. In the slot plate 18 having the `), the rest is filtered so that only a specific area is collected by the sensor 28, and the condensed minute signal is amplified by the amplifier 20 a few steps to select good or bad. It is a principle. Since the photosensitive device 101 is a very sensitive part, it is very important to protect the photosensitive device 101 from dust or foreign matter. To this end, the transparent plate 14 and the case 16 for protection and dust prevention are sealed so that there is no gap, and coated with an adhesive. In addition, by installing the air inlet 25 and the air shower system (Air Shower System) (24) in the detection unit (7) case 16 to prevent dust or foreign matter is fixed to the transparent plate (14). The air shower system can be used to stop the sorting work on a regular basis and to clean the detector. It can be cleaned effectively by cleaning the transparent plate by reciprocating left and right with a wiper with a brush while blowing air.

또한 검출부(7) 주위 전역을 집진시킬 수 있도록 집진장치(102)를 설치한다. 이때 정확한 검출을 위하여 입상물질의 양품색과 같은 색의 기준색으로 된 반사판(15)을 앞, 뒤 검출부(7)의 감광기 밑에 만들어 주어 감광기(7)가 맞은 편 반사판과 일직선상에서 바라보게 하되 앞, 뒤 감광기(7)는 통과하는 입상물질 앞, 뒤로 검사할 수 있도록 도 1의 공통점(6)에 서로 바라볼 수 있는 위치에 둔다. 따라서, 불량품이 왔을 때 선명하게 불량을 감지할 수 있도록 하는 역할을 할 수 있도록 한다. 이 반사판은 사각회전식으로 되어 있다.In addition, a dust collector 102 is installed to collect the entire area around the detector 7. At this time, for accurate detection, a reflector plate 15 having a reference color of the same color as the good color of the granular material is made under the photoreceptors of the front and rear detectors 7 so that the photoreceptor 7 faces in a straight line with the opposite reflector. However, the front and rear photoreceptors 7 are placed at positions common to each other at the common point 6 of FIG. Therefore, it is possible to play a role that makes it possible to clearly detect the defect when the defective article comes. This reflector is a square rotation type.

또한 감광기(101)에서 선별된 불량품은 그 신호가 이젝터(8)에 전달이 되어 순간적으로 공기를 분사하여 불량품을 불량수거출구(11)로 보내도록 해야 하는데 입상물질이 떨어지는 낙하속도는 초당 수백 개로 초고속인데 종래에는 주로 원형으로 이루어져 있는 공기분사노즐을 사용함에 따라 넓은 공간에 공기가 분사하여 양품손실이 많아지고 정확도도 떨어지는 문제가 있다. 본 발명은 이를 해결하기 위하여 도 4에서 알 수 있듯이, 원형 대신 슬롯형의 노즐구멍을 사용하여 정확도를 높였으며 슬롯(19)의 크기는 감광기(101)의 슬롯(18') 크기와 비례하여 적당한 크기를 만들었다. 이젝터(8)의 구성은 제 4도에 나타나 있으며 상술하면 사각의 금속통(29)에 각 슬롯(19)과 연결되는 내부구멍(31)을 길게 관통시키고, 그 좌,우선단은 콤프레샤호-스와 연결하여 항상 정압의 공기가 초고속으로 분사 작동토록 하여 색채선별기의 정확도를 높이고 생산성을 향상시켰다. 이젝터(8)가 공기를 고압으로 분사 시 고압의 공기가 검출부(7) 외부의 공기 흐름을 방해하고 분진 발생시키는 문제가 있을 수 있는데 이를 최소화시킬 목적으로 도 1에서 나타난 바와 같이, 검출부(7)와 이젝터(8) 간에는 분리벽(9)이 설치되어 있다.In addition, the defective product sorted by the photoreceptor 101 is to be transmitted to the ejector 8, the signal is sent to the ejector 8 instantaneously send the defective product to the defective collection outlet 11, the falling rate of falling granular material is several hundred per second It is a high-speed opening, but in the past, air is sprayed in a large space by using an air spray nozzle mainly made of a circle, which leads to a problem in that loss of yield increases and accuracy decreases. In order to solve this problem, as can be seen in FIG. 4, the accuracy is improved by using a slotted nozzle hole instead of a circle, and the size of the slot 19 is proportional to the size of the slot 18 ′ of the photoreceptor 101. Made the right size. The configuration of the ejector 8 is shown in FIG. 4, and in detail, the inside hole 31 connected to each slot 19 is long passed through the rectangular metal cylinder 29, and the left and right ends thereof are the compressor. The constant pressure air is always sprayed at high speed by connecting the switch to increase the accuracy of the color sorter and improve the productivity. When the ejector 8 injects the air at a high pressure, there may be a problem that the high-pressure air interferes with the air flow outside the detector 7 and generates dust, as shown in FIG. 1 for the purpose of minimizing the dust. The separation wall 9 is provided between the and ejector 8.
