Abstract

본 발명은 담배 적용 필터의 조립공정에 의해 각기 다른 성분의 필터를 일정 주기별로 배열하여 연속 제조된 복합필터의 검사장치 및 방법에 관한 것으로서, 이는 육안검사에 의존했던 종래의 제반적인 문제점을 해소하고자 하는 것이다.The present invention relates to an inspection apparatus and method for a composite filter continuously manufactured by arranging filters of different components at regular intervals by an assembling process of a cigarette application filter, which is intended to solve the conventional problems that depended on visual inspection. It is.

이에 따른 본 발명은 각기 다른 성분을 갖는 적어도 두개 또는 세개의 필터를 연속접합하여 된 복수조의 복합필터가 소정의 선속도로 이동되는 상태에서 복합필터의 배열 및 치수길이 검출을 전기적인 신호로 파형화하고, 이 검출 파형신호에서 진폭 및 펄스폭 순으로 분리한 후 복합필터의 진폭 및 펄스폭을 각각 계수하여 기준클록수와 비교한 결과치의 판별에 의해 복합필터의 각 필터 배열상태와 각 필터 치수길이를 표식화하도록 한 방법 및 장치를 제공하므로서, 복합필터 검사의 정확도를 기함과 아울러 검사속도의 향상으로 검사시간을 대폭적으로 단축할 수가 있고, 또한 복합필터의 필터유니트의 배열상태와 치수길이의 불량을 필터조립 공정중에 검사가 가능한 것이어서 검사효율을 향상시킬 수가 있는 효과를 제공한다.Accordingly, the present invention correlates the arrangement and dimension length detection of the composite filter with an electrical signal in a state in which a plurality of composite filters formed by successively joining at least two or three filters having different components are moved at a predetermined linear velocity. After separating the detected waveform signal in the order of amplitude and pulse width, the filter array state and the length of each filter of the composite filter are determined by discriminating the result of comparing the amplitude and pulse width of the composite filter with the reference clock number. By providing a method and apparatus for labeling, the inspection time can be drastically reduced by improving the inspection speed of the composite filter, and the arrangement state and the dimensional length of the filter unit of the composite filter are poor. It can be inspected during the filter assembly process, thereby providing the effect of improving the inspection efficiency.
