Abstract

A torch having a sensor detecting the light emitted from a cut object and a cutting machine using the same are provided to perform accurate cutting by controlling the torch to move only when the light is detected uniformly. A cutting machine comprises a torch(100) and a controller(170). The torch discharges hot air through a preheat outlet(127) in order to preheat an object to a preset temperature, and discharges high pressure cutting gas through a high pressure cutting gas outlet(113) in order to cut the preheated object while moving according to the signal from the controller. The torch is equipped with a light sensor(160) to detect the light generated from the object cut by the high pressure cutting gas and transmit the sensing signal to the controller. The controller determines completion of cutting when the signal from the light sensor is uniform, and then moves the torch.

Description

토치절단장치 및 이에 사용되는 토치{Torch cutting machine and torch}Torch cutting device and torch for use {Torch cutting machine and torch}

본 발명은 토치절단장치에 관한 것으로, 보다 상세하게는 피절단물이 절단될 때 발생되는 빛을 센서를 통해 감지하여 절단 작업이 완료된 후에만 토치가 위치 이동을 하면서 연속적인 절단작업을 수행할 수 있도록 개선된 토치절단장치에 관한 것이다.The present invention relates to a torch cutting device, and more particularly, it is possible to perform a continuous cutting operation while moving the position of the torch only after the cutting operation is completed by detecting light generated when the cutting object is cut through the sensor. It relates to an improved torch cutting device.

일반적으로 토치절단장치는 피절단물 상에 설치된 토치가 입력된 신호에 따라 전후, 좌우로 이동하면서 토치에서 토출되는 열을 통해 피절단물을 절단하는 장치로, 평판이나 H-형강 등을 절단하는 데 널리 사용되고 있다.In general, the torch cutting device is a device that cuts a to-be-cutting object through the heat discharged from the torch while moving the torch installed on the cutting object back and forth, left and right according to the input signal. Widely used.

그러나, 이와 같은 토치절단장치는 열을 가해 피절단물을 절단하는 과정에서 에러가 발생되었다 하더라도 이를 감지하지 못하고 계속 절단 작업을 실행하다 보니 종종 피절단물이 부분적으로 정확하게 절단되지 못하는 문제점이 있었다. 예를 들면, 열이 가해지는 부분에 바람이 불거나, 피절단물이 움직이거나, 피절단물의 절단부분에 기포가 있거나, 토치의 움직임이 변했을 때 등과 같은 변화가 있으면, 절단 작업이 올바르게 실행되지 않고, 이로 인해 피절단물이 부분적으로 절단되지 않는 문제점이 있었다.However, such a torch cutting device does not detect even if an error occurs in the process of cutting the cutting object by applying heat, and thus, the cutting operation is often not carried out. For example, if there is a change in the area where the heat is applied, a wind blows, the cut is moved, there is air bubbles in the cut, or the torch is changed, the cutting operation will not be performed correctly. In this case, there is a problem that the cutting object is not partially cut.

이를 개선하기 위해, 대한민국 공개특허 제2006-0075629호에는 토치 절단 속도 제어식 토치절단장치 및 이를 이용한 절단 방법이 개시되어 있다. 이 특허에 개시된 토치절단장치는, 주편을 절단하기 위하여 주편의 절단 방향으로 이동하는 적어도 하나의 토치와, 절단되는 주편의 표면 온도를 측정하는 온도 센서 유닛과, 측정된 주편의 표면 온도를 기초로 토치의 이동 속도를 제어하는 제어기를 포함하여 구성된 것을 특징으로 한다. 즉, 주편의 예열 온도를 감지하여 예열 온도가 설정 온도 범위 내에 있으면 그 부분이 절단되었다는 것으로 판단하고 토치가 다음 위치로 연속적으로 이동하면서 절단 작업을 계속 실행하는 것이다.In order to improve this, Korean Patent Laid-Open Publication No. 2006-0075629 discloses a torch cutting speed controlled torch cutting device and a cutting method using the same. The torch cutting device disclosed in this patent is based on at least one torch moving in the cutting direction of the slab to cut the slab, a temperature sensor unit measuring the surface temperature of the slab to be cut, and the measured surface temperature of the slab. And a controller for controlling the moving speed of the torch. In other words, if the preheating temperature of the cast steel is detected and the preheating temperature is within the set temperature range, it is determined that the part has been cut, and the torch continuously moves to the next position to continue the cutting operation.

그러나, 주편(피절단물)의 온도를 감지하여 피절단물이 절단되었음을 판단하는 것은 주변 환경이 항상 일정할 경우에만 정확하게 절단작업이 실행되는 단점이 있었다. 즉, 상술한 바와 같이, 열이 가해지는 부분에 바람이 불거나, 피절단물이 움직이거나, 피절단물의 절단부분에 기포가 있거나, 토치의 움직임이 변했을 때는 종래와 동일하게 피절단물이 부분적으로 절단되지 않는 문제점이 여전히 생기는데, 피절단물의 예열 온도를 감지하는 것 만으로는 이러한 문제들을 확인할 수 없었던 것이다.However, the determination of the cutting object by sensing the temperature of the slab (the cutting object) has a disadvantage in that the cutting operation is executed correctly only when the surrounding environment is always constant. That is, as described above, when the wind blows on the part to which heat is applied, the cutting object moves, or there are bubbles in the cutting part of the cutting object, or when the movement of the torch changes, the cut object is partially There is still a problem that is not cut by the sensor, the detection of the preheating temperature of the cutting was not able to identify these problems.

본 발명은 상술한 문제점을 개선하기 위해 제안된 것으로, 그 목적은 토치에서 피절단물이 절단될 때 발생되는 빛을 감지하여 빛이 균일하게 감지될 때에만 토치가 이동되도록 함으로 항상 정확한 절단 작업이 실행될 수 있도록 개선된 토치절단장치를 제공하는 데 있다.The present invention has been proposed to improve the above-mentioned problem, and its object is to detect the light generated when the cutting object is cut in the torch so that the torch is moved only when the light is uniformly detected so that accurate cutting operation is always performed.

Here, the on-off valve B for selectively supplying and cutting off the high pressure cut gas is installed on a line connecting the high pressure cut gas cylinder 150 and the high pressure cut gas inlet 112.

그리고 예열경로(121)의 상부에는 LPG통(130)에서 공급되는 LPG가 유입되는 LPG유입구(122)와 산소통(140)에서 공급되는 산소가 유입되는 산소유입구(123)가 형성되며, 예열경로(121)의 하부에는 예열토출구(127)가 형성된다. 그리고 유입된 LPG와 산소는 서로 혼합된 상태로 예열경로(121)로 안내되게 구성된다. 즉, 내통(110)의 상단에는 LPG유입구(122)와 연통되는 LPG연통홈(124)이 형성되고, 이 LPG연통홈(124)과 예열경로(121)를 연통시키는 혼합공(126)이 수직으로 관통 형성되며, LPG연통홈(124) 보다 하부에는 산소유입구(123)와 연통되는 산소유입구(123)이 혼합공(126)과 연통되게 관통 형성된다. 따라서 LPG유입구(122)를 통해 유입된 LPG가 LPG연통홈(124)을 통해 혼합공(126)으로 안내되어 예열경로(121)로 이동될 때 산소유입구(123)를 통해 유입된 산소가 산소유입구(123)을 통해 혼합공(126)으로 안내되면서 산소와 LPG가 혼합된 상태로 예열경로(121)로 이동된다. 여기서, LPG통(130)과 LPG유입구(122)를 연결하는 라인 상에는 LPG를 선택적으로 공급 및 차단하기 위한 개폐밸브(B)가 설치되고, 산소통(140)과 산소유입구(123)를 연결하는 라인 상에는 산소를 선택적으로 공급 및 차단하기 위한 개폐밸브(B)가 설치된다.In addition, the upper portion of the preheating path 121 is provided with an LPG inlet 122 through which the LPG supplied from the LPG barrel 130 flows in and an oxygen inlet 123 through which the oxygen supplied from the oxygen cylinder 140 flows in.

In this case, the spark means may apply a known technique, and thus a detailed description of the spark means will be omitted.

다음으로, 고압절단가스경로(111)의 상단에는 고압절단가스가 피절단물을 절단시킬 때 발생되는 빛을 감지하여 그 신호를 제어부(170)로 송신하는 빛감지센서(160)가 설치된다.Next, a light detection sensor 160 is installed at the upper end of the high pressure cut gas path 111 to detect light generated when the high pressure cut gas cuts the cutting object and transmit the signal to the controller 170.

이와 같이 구성된 토치가 적용된 토치절단장치의 작동을 설명하면, 제어부(170)에서 신호를 송신하여 토치(100) 내로 LPG와 산소를 공급하면 LPG와 산소가 혼합공(126)을 통과하면서 혼합되어 예열경로(121)로 안내된다. 이때, 스파크수단(180)에서 스파크를 공급하여 혼합 가스에 불을 붙이게 되면, 이 불이 토치(100)의 예열토출구(127)를 통해 토출되면서 피절단물을 1500℃ 내지 2500℃ 정도로 예열시키게 된다. 피절단물의 예열이 완료되면 토치(100)의 고압절단가스유입구(112)를 통해 고압절단가스가 고압으로 유입되어 고압절단가스토출구(112)를 통해 토출되면서 피절단물을 절단하게 된다. 이때, 본 발명은 고압절단가스경로 상에 빛감지센서(160)가 설치되어 피절단물이 절단될 때 발생되는 빛을 감지하여 제어부(170)로 신호를 송신하게 된다. 그리고 제어부(170)에서는 빛감지센서(160)에서 송신되는 신호를 수신하여 항상 일정하게 신호가 송신되면 정확하게 절단 작업이 실행되었음을 판단하여 계속 연속적인 절단 작업을 실행하도록 토치(100)를 이동시키게 된다.Referring to the operation of the torch cutting device to which the torch configured as described above is applied, when LPG and oxygen are supplied from the control unit 170 to the torch 100, the LPG and oxygen are mixed while passing through the mixing hole 126 to be preheated. Guided by path 121. At this time, when the spark is supplied from the spark means 180 to ignite the mixed gas, the fire is discharged through the preheating discharge port 127 of the torch 100 to preheat the cutting object to 1500 ℃ to 2500 ℃ degree. . When the preheating of the cutting object is completed, the high pressure cutting gas is introduced into the high pressure through the high pressure cutting gas inlet 112 of the torch 100 and is discharged through the high pressure cutting gas outlet 112 to cut the cutting object. At this time, in the present invention, the light detecting sensor 160 is installed on the high-pressure cutting gas path to detect the light generated when the cutting object is cut and transmit a signal to the control unit 170. In addition, the control unit 170 receives the signal transmitted from the light sensor 160 and always transmits the torch 100 to continuously execute the cutting operation by determining that the cutting operation is correctly performed when the signal is constantly transmitted. .

특히, 본 발명을 적용하면 종래와 같이 외부 요인에 의해 피절단물이 부분적으로 절단되지 않는 문제점이 개선된다. 즉, 통상적으로 열이 가해지는 부분에 바람이 불거나, 피절단물이 움직이거나, 피절단물의 절단부분에 기포가 있거나, 토치의 움직임이 변하는 등에 외부 요인에 의해 피절단물의 절단 작업이 정확히 이루어지지 않으면 빛감지센서에서 감지되는 빛이 흔들리거나 끊어지는 현상이 생기는 데, 제어부에서 이와 같이 빛이 흔들리거나 끊어지는 신호가 수신되면 토치의 이동을 제한하고, 절단 작업이 완벽하게 이루어지면서 빛의 신호가 균일하게 수신되면 토치의 이동을 명령하기 때문에 항상 정확한 절단 작업을 실행할 수 있게 된다.In particular, the application of the present invention improves the problem that the cutting object is not partially cut by external factors as in the prior art. That is, the cutting operation of the cutting object is accurately performed by external factors such as wind blowing on the part to which heat is applied, the cutting object moves, air bubbles in the cutting part of the cutting object, or the movement of the torch changes. If it does not, the light detected by the light sensor will be shaken or broken.If the light shake or broken signal is received from the controller, the movement of the torch will be limited, and the cutting operation will be made perfectly. Is uniformly received, it commands the movement of the torch so that the correct cutting operation is always performed.
