Description

용기 동체 검사장치{A Detecting Defects Apparatus of Bottle or Container}A Detecting Defects Apparatus of Bottle or Container

본 발명은 용기 동체 검사장치에 관한 것으로, 더욱 상세하게는 광원을 통해 조광된 용기의 영상을 반사경을 통해 각각 다른 각도에서 촬상할 수 있도록 구비된 CCD카메라에 전달해줌으로써 한 개의 조명기구로 편광검사와 이물질검사를 동시에 수행할 수 있도록 한 용기 동체 검사장치에 관한 것이다.The present invention relates to a container fuselage inspection device, and more particularly, by passing the image of the container dimmed through the light source to the CCD camera equipped to be taken from different angles through a reflecting mirror to one polarizer and The present invention relates to a container fuselage inspection device capable of simultaneously performing a foreign material inspection.

일반적으로 알콜이나 청량음료, 음식 등을 담는데 이용되는 유리병이나 플라스틱 등의 용기는 사용 후 회수하여 재활용하게 되는데, 재활용을 위한 공정으로 먼저 용기를 깨끗이 세척한 다음 용기의 이물질 잔류 및 파손유무를 검사하는 과정을 거치게 된다.Generally, containers such as glass bottles and plastics used to hold alcohol, soft drinks, and foods are collected and recycled after use.In the process for recycling, clean the containers first and then check for any residue or damage of the containers. You will be tested.

이때, 용기의 표면이나 동체, 용기 입구부 등의 파손여부와 이물질의 잔류 여부를 신속하게 검사하기 위하여 다수의 용기를 장착한 상태로 회전시키면서 CCD(Charge Coupled Device) 카메라를 통해 각 용기의 상태를 검사하도록 된 컨베이어 라인 형태의 용기 검사장치가 있다.At this time, in order to quickly inspect the surface, the fuselage, the inlet of the container, and the presence of foreign matter, the container is rotated with a plurality of containers mounted, and the state of each container is changed through a CCD (Charge Coupled Device) camera. There is a container inspection device in the form of a conveyor line intended for inspection.

여기에서, 종래의 용기 동체 검사는 크게 이물질검사와 편광검사로 나뉘어 이루어지는데, 도 1a 및 도 1b에 도시된 바와 같이 검사하고자 하는 용기(B)를 사이에 두고 조명기구(10)와 CCD카메라(20a, 20b)를 대향되게 배치하여, 조명기구(10)로부터 조광된 빛을 렌즈(30)를 통해 집중시켜 CCD카메라(20a, 20b)에영상을 맺히게 하는 것이다.Here, the conventional container fuselage inspection is largely divided into the foreign matter inspection and the polarization inspection, as shown in Figure 1a and Figure 1b, the lighting device 10 and the CCD camera ( 20a and 20b are disposed to face each other, thereby concentrating light emitted from the luminaire 10 through the lens 30 to form an image on the CCD cameras 20a and 20b.

이때, 상기 조명기구(10)는 형광등이나 LED, 할로겐 램프 등이 내입되어 확산필름(14) 또는 편광필름(12)이 장착된 전면부를 통해 빛을 발한다.At this time, the lighting fixture 10 is a fluorescent lamp, LED, halogen lamps, etc. are embedded to emit light through the front portion on which the diffusion film 14 or the polarizing film 12 is mounted.

따라서, CCD카메라(20a, 20b)를 통해 용기(B)의 동체에 이물질 잔류여부와 결함유무를 검사할 수 있어 부적합한 용기(B)를 분리,이송시킬 수 있는 것이다.Therefore, the CCD camera 20a, 20b can be inspected whether there is a foreign material remaining in the body of the container (B) and whether there is a defect, so that the inappropriate container (B) can be separated and transferred.

이때, 도 1b에서 도시된 바와 같이, 조명기구(10)의 전측면에 편광필름(12)을 구비하고, CCD카메라(20a, 20b)의 전측에 편광필터(22)를 장착해서 진행되는 편광검사는 편광의 특성상 결함이 있는 부위는 백색으로, 정상인 부위는 흑색의 영상으로 비춰지기 때문에 용기(B) 동체의 손상이나 파손 등의 결함을 검사할 수 있는 것이다.In this case, as shown in FIG. 1B, the polarization inspection is performed by including the polarizing film 12 on the front side of the luminaire 10 and installing the polarization filter 22 on the front side of the CCD cameras 20a and 20b. In the characteristic of the polarization, the defective part is white and the normal part is illuminated with a black image, so that defects such as damage or breakage of the container B body can be inspected.

그러나, 상기 이물질검사와 편광검사는 도 1a 및 도 1b에서 도시된 바와 같이 각각 독립적으로 이루어졌기 때문에 공정이 복잡하게 되고 부품수가 증가하게 되어 생산효율이 저하되었다.However, since the foreign matter inspection and the polarization inspection are independently performed as shown in FIGS. 1A and 1B, the process becomes complicated and the number of parts increases, thereby decreasing production efficiency.

또한, 이물질검사와 편광검사에 각각 다른 조명기구를 사용했기 때문에 설비 중복으로 인한 설비비 증가 및 불필요한 작업공수를 초래하였다.In addition, different lighting fixtures were used for the foreign material inspection and the polarization inspection, resulting in an increase in facility costs and unnecessary labor due to overlapping facilities.

이에 본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출된 것으로서, 용기 동체 검사시 한 개의 조명기구로 편광검사와 이물질검사를 동시에 수행할 수 있도록 하여 공정을 간소화하여 생산능률을 높이고 생산비를 절감하도록 함에발명의 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned problems in the related art, so that the polarization inspection and the foreign matter inspection can be performed at the same time with one luminaire during the inspection of the container body to simplify the process to increase the production efficiency and reduce the production cost The purpose of the invention is to.

이하, 본 발명의 바람직한 실시예를 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2에 도시된 바와 같이, 본 발명은 검사하고자 하는 용기(B)의 일측에는 편광필름(12)이 장착된 조명기구(10)가 배치되고, 상기 용기(B)를 사이에 두고 조명기구(10)와 대향되는 측에는 상기 조명기구(30)를 통해 조광된 용기(B)의 동체 영상을 반사시키는 반사경(40)이 하나 이상 배치되고, 상기 반사경(40)의 일측에는 반사경(40)을 통해 반사된 동체 영상을 촬상하는 CCD카메라(20a, 20b)가 배치되어있다.As shown in FIG. 2, in the present invention, a light fixture 10 equipped with a polarizing film 12 is disposed at one side of the container B to be inspected, and the light fixture (10) is disposed with the container B interposed therebetween. 10 and at least one reflector 40 reflecting the fuselage image of the container B illuminated through the lighting device 30 is disposed on one side of the reflector 40, and at one side of the reflector 40 through the reflector 40. CCD cameras 20a and 20b for capturing the reflected body image are arranged.

상기 CCD카메라(20a, 20b) 중 적어도 한 개는 전면부에 편광필터(22)가 장착되어 있어 편광필름(12)을 통해 조광된 빛으로 하여금 용기 동체의 편광검사가 가능하게 한다.At least one of the CCD cameras 20a and 20b is equipped with a polarization filter 22 on the front surface thereof to enable light dimmed through the polarizing film 12 to enable polarization inspection of the container body.

그리고, 상기 반사경(40)은 일측면에 서보모터(servomotor)(42)를 구비하여 반사경(40)마다 각각 독립적인 회동이 가능하게 한다.In addition, the reflector 40 includes a servomotor 42 on one side thereof to enable independent rotation of each reflector 40.

또한, 바람직하게 상기 조명기구(10)에는 광원으로써 메탈할레이드램프(미도시)를 내입하고, 조명기구의 전면부에는 프레넬렌즈(미도시)를 장착하여 조도를 높이고 검사의 정확성을 향상시키도록 한다.In addition, the luminaire 10 has a metal halide lamp (not shown) as a light source, and a Fresnel lens (not shown) is mounted on the front of the luminaire to increase the illuminance and improve the accuracy of the inspection. To do that.

아울러, 상기 서보모터(42)는 도면에는 미도시되었지만, 시스템 외부의 전력원 및 별도의 제어수단과 연동되어 사용자에 의해 수시로 제어될 수 있음은 물론이다.In addition, although not shown in the drawing, the servomotor 42 may be controlled from time to time by a user in conjunction with an external power source and a separate control means.

이와 같이 구성된 본 발명의 용기 동체 검사장치는 각각의 CCD카메라와 한 개의 조명기구를 통하여 편광검사와 이물질검사를 동시에 수행할 수 있는 것이다.The container fuselage inspection apparatus of the present invention configured as described above can perform polarization inspection and foreign matter inspection at the same time through each CCD camera and one lighting device.

즉, 확산판(12)과 편광필름(14)이 장착된 조명기구(30)의 빛은 용기(B)의 일측에서 용기(B)의 동체를 비추게 되고, 용기(B)를 관통한 빛은 소정각도로 배치된 반사경을 통해 반사된다.That is, the light of the luminaire 30 to which the diffuser plate 12 and the polarizing film 14 are mounted illuminates the body of the container B at one side of the container B, and the light penetrates the container B. Is reflected through a reflector disposed at a predetermined angle.

이후, 반사된 빛은 반사경(40) 일측에 배치된 CCD카메라(20a, 20b)에 집광.촬영되어 이물질 잔류여부와 파손.결함 여부가 판독되는 것이다.Thereafter, the reflected light is collected and photographed by the CCD cameras 20a and 20b disposed on one side of the reflector 40 to read whether the foreign matter remains and whether it is broken or defective.

이를 위해 상기 반사경(40)은 서보모터(42)에 의해 각각 독립적으로 회동이 가능하게 되어 있어, 다양한 방향에 배치된 CCD카메라(20a, 20b)에 용기 동체의 영상을 반사, 전달해줄 수가 있다.To this end, the reflector 40 can be independently rotated by the servo motor 42, and can reflect and transmit the image of the container body to the CCD cameras 20a and 20b arranged in various directions.

아울러, 수광된 용기(B) 동체의 영상은 반사경(40)의 회동에 따라 소망하는 위치로 전달될 수 있으므로, 상기 CCD카메라(20a, 20b)의 배치위치를 자유자재로 할 수 있어 공간의 효율적 활용이 가능한 것이다.In addition, since the image of the received container B body can be delivered to a desired position according to the rotation of the reflector 40, the position of the CCD cameras 20a and 20b can be freely set, thereby making space efficient. It can be used.

따라서, 편광필터(22)가 구비된 CCD카메라(20b)로 편광검사를 수행하고, 또 다른 CCD카메라(20a)로 이물질검사를 수행할 수 있어 한 개의 조명기구(10)로 편광검사와 이물질검사가 동시에 진행될 수 있는 것이다.Therefore, polarization inspection can be performed by the CCD camera 20b equipped with the polarization filter 22, and foreign matter inspection can be performed by another CCD camera 20a. Can be done at the same time.

이상에서 설명한 바와 같이 본 고안은 용기 동체의 이물질검사와 편광검사를 동시에 수행할 수 있어 공정을 간소화시키고 생산비를 절감할 수 있어 매우 유용한 발명인 것이다.As described above, the present invention is a very useful invention because it can perform the foreign material inspection and polarization inspection of the container body at the same time to simplify the process and reduce the production cost.
