Abstract

본 발명은 가스 절단시스템, 예컨대 NC 가스 절단기, 로보트 절단 장치등에 적용되어 절단 어긋남의 보정제어에 이용할 수 있도록 한 피절단재 위치 검출 방법에 관한 것으로서, 이는 종래 기술로서 피절단재와 탐촉자간의 접촉식이므로 고속운전의 경우 위치센싱이 되는 순간 탐촉자에 의해 피절단재가 밀리거나, 탐촉자가 손상되기 쉬워 절단위치변경 내지는 면취절단이 곤란하고 기구의 거대화에 따른 단점이 있을 뿐만 아니라, 탐촉자와 피절단재 사이에 고전압을 걸어 주므로 감전사고 등의 안전도가 뒤떨어 접촉식과, 광센서 및 배압센서에 의한 비접촉식의 문제점을 해소하고자 하는 것이다.The present invention relates to a method for detecting the position of the cut material applied to a gas cutting system such as an NC gas cutting machine, a robot cutting device, etc., which can be used for the control of cutting misalignment. In the case of high speed operation, the cutting material is pushed by the transducer at the moment of position sensing, or the transducer is easily damaged, so it is difficult to change the cutting position or chamfering, and there is a disadvantage due to the enlargement of the mechanism. Since the high voltage is applied, the safety of an electric shock accident, etc. is inferior, and the problem of the non-contact type by the optical sensor and the back pressure sensor is to be solved.

이에 따른 본 발명은 절단팁과 피절단재에 전원을 인가한 상태에서 절단팀을 피절단재의 일단부로 이동하면 화염에 의한 부하저항의 전압강하로 피절단재의 위치를 검출하도록 한 방법제시로 기존의 절단시스템의 자동, 반자동 절단기등에서는 이용할 수 없었던 초기위치 검출 및 어긋남의 보정등이 가능하고, 토치주변기구부의 간략구성과 비접촉식의 전압변위에 의해 위치검출이 가능하므로 경제적이면서 접촉식에 비해 절단의 정확도를 얻을 수가 있고, 아울러 절단기구부의 파손위험이 적을 뿐만 아니라, 열악한 절단작업 환경에 대한 내구성이 기존의 광센서 및 배압센서에 의한 비접촉식에 비해 우수하므로 로보트를 이용한 절단 시스템에 적용할 경우 매우 합리적인 성과를 얻을 수가 있는 효과를 제공한다.Accordingly, the present invention provides a method for detecting the position of the cutting material by the voltage drop of the load resistance caused by the flame when the cutting team is moved to one end of the cutting material while the power is applied to the cutting tip and the cutting material. Initial position detection and misalignment correction, which were not available in automatic and semi-automatic cutters of cutting systems, are possible, and the position can be detected by the simple configuration of the torch peripheral mechanism and the non-contact voltage displacement. It is very reasonable when applied to the cutting system using robot because accuracy can be obtained, and the risk of breakage of cutting part is not only small, but also the durability against the severe cutting work environment is superior to the non-contact type by the conventional optical sensor and back pressure sensor. Provides an effect that can be achieved.
