Description
본 발명은 카메라를 이용하여 각종 음료 또는 장류와 같은 액체를 보관하는 용기의 밀폐용 캡핑(CAPPING) 검사방법에 관한 것으로, 카메라를 1대 또는 2대를 90°방향으로 설치하여 용기 밀폐용 캡의 밀폐불량을 검색할 수 있도록 하는 용기의 캡핑 검사방법에 관한 것이다.The present invention relates to a sealing capping (CAPPING) inspection method of a container for storing liquids, such as beverages or drinks, by using a camera, the installation of one or two cameras in the 90 ° direction of the cap for sealing the container The present invention relates to a capping inspection method of a container to detect a defect in sealing.
종래 각종 음료용기 또는 장류 등의 액체를 저장하는 용기는 금속 또는 프라스틱으로 성형된 캡으로 밀폐시켜 내용물이 공기 접촉을 방지하게 된다.Conventionally, a container for storing liquids such as various beverage containers or foods is sealed with a cap formed of metal or plastic to prevent contents from contacting with air.
그러나 생산라인에서 캡으로 밀폐시키는 과정에서 캡(3)의 절단링(4)이 절취선(5)을 따라서 브릿지로 연결되도록 하나, 절취선의 브릿지 일부분이 연결되지 않아 절단링이 떨어진 경우가 발생하게 되며, 절단링이 아예 없이 생산되는 경우가 발생한다.However, in the process of sealing the cap in the production line, the cutting ring (4) of the cap (3) is connected to the bridge along the perforated line (5), but the cutting ring is dropped because the bridge portion of the perforated line is not connected. In some cases, the cutting ring is produced without any.
용기의 상측에서 캡과 절단링이 절단되어 있거나 절단링이 없는 상태로 유통되면 내용물이 공기와 접촉되어 상하거나 병균이 침투하여 질병을 발생시키게 되므로 제품의 신뢰도를 저하시키는 원인이 된다.If the cap and the cutting ring are cut or distributed in the absence of the cutting ring at the upper side of the container, the contents may come into contact with the air, causing the disease to penetrate or cause germs to deteriorate the reliability of the product.
이러한 캡의 밀폐불량을 검사하는 방법은 후면에 카메라를 설치하여 절취선이 벌어진 모양을 화상으로 받아 비교하는 방법으로 검사하게 된다.The method of inspecting the sealing failure of the cap is to install the camera on the back side to examine the image of the perforated line open and compare it.
그러나 상기의 캡핑 검사방법은 수입되는 고가의 장비이어서 구입이 어렵고 대중화되지 못하는 결점이 있다.However, the capping test method is a high-cost imported equipment is difficult to purchase and popularized has the drawback.
본 발명은 캡의 전방에서 카메라 1대 또는 2대를 90°방향으로 설치하여 캡의 절단링과 용기의 돌출부 간격을 양측(180°)에서 비교하여 캡의 갭을 찾아 캡핑을 검사하는 것이다.The present invention is to install one or two cameras in the front of the cap in the 90 ° direction to compare the gap between the cutting ring of the cap and the protrusion of the container from both sides (180 °) to find the gap of the cap and inspect the capping.
본 발명은 캡의 갭을 토대로 캡의 열림, 없음, 절단링 떨어짐, 절단링 없음, 15°틀어진 캡핑 박힘 등을 검출할 수 있도록 하는 것이다.The present invention makes it possible to detect opening, absence, cutting ring drop, no cutting ring, 15 ° twisted capping, etc., based on the gap of the cap.
본 발명은 전방에 1대 또는 2대의 카메라를 설치하여 양측면 또는 사면에서 절단링과 용기의 돌출부 간격을 체크한 후 계산하여 캡핑 검사할 수 있도록 함을 특징으로 하는 것이다.The present invention is characterized in that by installing one or two cameras in front to check the gap between the cutting ring and the protrusion of the container on both sides or slopes to calculate and capping inspection.

본 발명의 캡핑 검사시스템은 도 1 에 도시한 바와 같이, 용기(1)의 상측에 밀봉되는 캡(3)의 전방으로 카메라(6)를 설치하고 후방에 백 라이트(8)를 형성하여 캡(3)의 양측면에서 검사할 수 있도록 한다,In the capping inspection system of the present invention, as shown in FIG. 1, the camera 6 is installed in front of the cap 3 sealed on the upper side of the container 1, and the back light 8 is formed at the rear of the cap 3. Inspect on both sides of 3),
캡(3)의 상측에는 캡 감지센서(9)를 설치하여 캡(3)이 형성된 용기(1)의 이송을 감지하며, 비젼 시스템(10)에서는 카메라(6)에 클로즈업된 화상을 확인 및 검사할 수 있도록 하는 것이다.A cap detection sensor 9 is installed on the upper side of the cap 3 to detect the transfer of the container 1 in which the cap 3 is formed, and the vision system 10 checks and inspects an image close-up on the camera 6. To do it.
용기(1)의 상부에는 돌출부(2)가 형성되고 캡(3)의 하측으로 절취선(5)이 형성되어 브릿지를 통하여 절단링(4)과 연결되어 밀폐되도록 하는 것이다.A protrusion 2 is formed on the upper part of the container 1, and a cut line 5 is formed below the cap 3 so as to be connected to the cutting ring 4 through a bridge to be sealed.
용기(1)의 색상 또는 성형모양에 따라 환경의 변화가 있을 수 있으므로 조명의 밝기를 조절하여 최대한 검사환경에 적합하도록 한다.Since there may be a change in the environment depending on the color or shape of the container (1) to adjust the brightness of the illumination to suit the inspection environment as possible.
상기 카메라(6)는 도 2 에서와 같이 1대를 설치할 수 있으며, 캡(3)의 전면에 설치되어 양선단에서 캡(3)의 하측에 연결된 절단링(4)과 돌출부(2)의 간격을 180°되는 지점의 검사영역(12)에서 캡핑 검사할 수 있도록 한다.The camera 6 may be installed as shown in Figure 2, the gap between the cutting ring (4) and the projection (2) is installed on the front of the cap (3) connected to the lower side of the cap (3) at both ends To be capped at the inspection area 12 at a point of 180 °.
또한 도 3 에서와 같이 카메라(6)에서 90°의 각도를 가지고 설치되는 또다른 카메라(7)를 설치하는 2대의 카메라(6)(7)를 설치하여 카메라(6)는 양측의 검사영역(14)을 검사하고, 카메라(7)는 양측의 검사영역(13)에서 캡핑 검사할 수 있도록 한다.In addition, as shown in FIG. 3, two cameras 6 and 7 for installing another camera 7 installed at an angle of 90 ° from the camera 6 are installed so that the camera 6 has an inspection area on both sides ( 14) and the camera 7 allows capping inspection in the inspection areas 13 on both sides.
상기 캡핑 검사방법은 2방향 선분에 대한 벡터 값을 이용한 것으로 두 방향에 대한 수직인 성분을 추출하는 방법이다.The capping test method is a method of extracting components perpendicular to two directions by using vector values of two-way segments.
이 검사방법은 실제 검사에 있어서 환경설정은 2방향선분의 각도로써 제어된다.In this inspection method, in the actual inspection, the configuration is controlled by the angle of the two-way line segment.
즉, 절단링(4)의 최하측과 돌출부(2)의 간격을 2방향선분의 각도인 간격 (S)(S')의 거리를 계산하는 것이다.That is, the distance of the space | interval S (S ') which is the angle of the two-way line | wire is the space | interval of the lowermost side of the cutting ring 4, and the protrusion part 2 is calculated.
간격(S)(S')을 계산하는 방법은 예를 들어 480(Pixe 1) * 480(Pixe 1)에서 3㎝ × 3㎝의 이미지 사이즈로 영상을 볼 때 1Pixe 1이 차지하는 사이즈는 0.0625㎜/Pixe 1 이다.The method of calculating the interval S (S ') is, for example, when viewing an image at an image size of 3 cm x 3 cm at 480 (Pixe 1) * 480 (Pixe 1), the size occupied by 1Pixe 1 is 0.0625 mm / Pixe is 1.
동일한 480 * 480 이미지라 하여도 차지하는 영상의 비율에 따라서 계산치는 바뀔 수 있다.Even in the same 480 * 480 image, the calculated value may be changed according to the proportion of the image occupied.
캡(3)의 주변인 검사영역(11)을 자세히 볼 수 있도록 하고 취득된 외곽선이 뚜렷해야 한다.The inspection area 11, which is the periphery of the cap 3, can be seen in detail and the acquired outline must be clear.
결국 전방에서 1대의 카메라(6)를 사용하거나, 2대의 카메라(6)(7)를 사용하는 경우에는 백라이트(8)를 통하여 검사영역(11)에 카메라(6)(7)를 통하여 캡(3)의 양측 외곽선이 취득된다.As a result, when one camera 6 is used from the front or two cameras 6 and 7 are used, the cap (through the cameras 6 and 7) is connected to the inspection area 11 through the backlight 8. Both side outlines of 3) are obtained.
1대의 카메라(6)를 이용하는 경우에는 캡(3)의 검사영역(12)에서 간격 (S)(S')을 계산하여 비교함으로써 캡핑 검사한다.When one camera 6 is used, capping inspection is performed by calculating and comparing the interval S (S ') in the inspection region 12 of the cap 3.
또한 2대의 카메라(6)(7)를 이용하는 경우에는 캡(3)의 검사영역(13)(14)에서 간격(S)(S')을 계산하여 거리에 오차가 발생되는 경우 불량이 검출되는 것이다.In addition, when two cameras 6 and 7 are used, gaps S and S 'are calculated in the inspection areas 13 and 14 of the cap 3 so that an error is detected when an error occurs in the distance. will be.
따라서 1대의 카메라(6)를 사용하는 경우에는 2곳의 검사영역(12)을 검사하므로 절단링(4)의 떨어짐이 미세한 경우 검출되지 않을 수도 있으므로 2대의 카메라(6)(7)를 사용하는 경우 4곳의 검사영역(13)(14)을 검사하여 미세한 불량의 검출이 가능하게 된다.Therefore, when one camera 6 is used, two inspection areas 12 are inspected, so when the fall of the cutting ring 4 is minute, it may not be detected, so two cameras 6 and 7 are used. In this case, four inspection areas 13 and 14 can be inspected to detect minute defects.
테스트 결과 0.0625㎜ ×5Pixe 1(허용치)는 약 0.3㎜의 허용치를 두어 검사시 검사가 거의 완벽한 것으로 나타났다.As a result of the test, 0.0625mm x 5Pixe 1 (tolerance) had a tolerance of about 0.3mm, and the inspection was almost perfect during the inspection.
즉, 캡(3)의 열림은 0.3㎜ 이상시 검사효율이 99.9% 이었고, 캡(3)이 없는 경우에는 검사효율이 99.99% 이었으며, 절단링(4)의 떨어짐(1㎜ 이상)은 검사효율이 99.9% 이었고, 절단링(4)이 없는 경우에는 검사효율이 99.99% 이었으며, 15°틀어진 캡핑 박힘은 검사효율이 99.99% 이었다.That is, the inspection efficiency was 99.9% when the cap 3 was opened at 0.3 mm or more, and the inspection efficiency was 99.99% when the cap 3 was not present, and the falling off of the cutting ring 4 (1 mm or more) was the inspection efficiency. This was 99.9%, the absence of the cutting ring (4) was 99.99% inspection efficiency, 15 ° twisted capping nailing was 99.99% inspection efficiency.
결국 검사효율을 높이기 위해서는 카메라의 설치 댓수를 증가시키면 되나 본 발명과 같이 2대의 카메라(6)(7)를 설치하는 경우에도 거의 완벽한 캡핑 검사가 가능하였다.As a result, in order to increase the inspection efficiency, the number of installations of the camera may be increased, but even when two cameras 6 and 7 are installed as in the present invention, a nearly perfect capping inspection is possible.
본 발명은 캡의 전방에서 카메라 1대 또는 2대를 90°방향으로 설치하여 캡의 절단링과 용기의 돌출부 간격을 양측(180°)에서 비교하여 캡의 갭을 찾아 캡핑을 0.1%이하의 오차범위에서 정확하게 검사할 수 있는 것이다.According to the present invention, one or two cameras are installed in a 90 ° direction from the front of the cap to compare the gap between the cutting ring of the cap and the protrusion of the container at both sides (180 °) to find the gap of the cap, and the capping error is 0.1% or less. It can be tested accurately in the range.
본 발명은 캡의 갭을 토대로 캡의 열림, 캡 없음, 절단링 떨어짐, 절단링 없음, 15°틀어진 캡핑 박힘 등을 검출할 수 있도록 하는 것이다.The present invention makes it possible to detect the opening of the cap, no cap, no cutting ring falling, no cutting ring, 15 ° twisted capping, etc. based on the gap of the cap.
