The phenomenon occurs, and thus there is a problem such as wrinkles or incorrect cutting of the fabric because it can not quickly and accurately cope with the fluctuation of the edge line of the fabric.
따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로 그 목적은, 적외선 센서의 반사량에 따라 구동부의 이동위치를 복수 단계로 결정하고 이에 따른 각각의 제어신호를 출력하여 원단의 끝단을 정밀하게 제어함으로써 헌팅현상 등을 방지하는 EPC 빔 센서 장치를 제공함에 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object of which is to determine the moving position of the driving unit in a plurality of stages according to the amount of reflection of the infrared sensor and output the respective control signals according to the end of the far end The present invention provides an EPC beam sensor device that prevents hunting phenomenon by precisely controlling the temperature.

이하, 본 발명에 따른 EPC 빔 센서 장치의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the EPC beam sensor device according to the present invention will be described in detail.
도 1은 본 발명에 따른 EPC 빔 센서 장치의 제어 블록도이다. 도시된 바와 같이, 적외선 출력부(20)는 원단(90)의 끝선을 감지하기 위하여 렌즈부(10)를 거쳐 소정 범위에 적외선을 조사하고, 적외선 입력부(30)는 상기 원단(90)으로부터 반사되는 적외선 반사량을 측정한다. 또한, 표시부(40)는 상기 적외선 입·출력부(20)(30)의 동작상태를 표시한다.1 is a control block diagram of an EPC beam sensor device according to the present invention. As shown, the infrared output unit 20 irradiates infrared rays to a predetermined range through the lens unit 10 to detect the end line of the far end 90, the infrared input unit 30 is reflected from the far end 90 Infrared reflectance is measured. In addition, the display unit 40 displays the operating states of the infrared input / output units 20 and 30.
신호 증폭부(50)는 상기 적외선 입력부(20)를 통하여 입력된 신호를 증폭하고, 제어부(60)는 상기 신호 증폭부(50)로부터 증폭된 신호를 입력받아 적외선 반사량에 따라 구동부(80)의 이동위치를 복수 단계로 결정하고 이에 따른 각각의 제어신호를 설정한다. 또한, 신호 출력부(70)는 상기 제어부(60)의 제어신호에 의한 구동신호를 출력한다.The signal amplification unit 50 amplifies the signal input through the infrared input unit 20, and the control unit 60 receives the amplified signal from the signal amplification unit 50 and according to the amount of infrared reflection of the driving unit 80 The movement position is determined in plural steps and the respective control signals are set accordingly. In addition, the signal output unit 70 outputs a driving signal according to the control signal of the control unit 60.
아울러, 본 발명에서 사용되는 적외선 센서로 출력부(20)에는 고휘도 LD 또는 LED, 입력부(30)에는 CdS와 같은 고감도 검출소자를 사용하는 것이 바람직하다.In addition, it is preferable to use a high-sensitivity detection element such as high brightness LD or LED for the output unit 20 and CdS for the input unit 30 as the infrared sensor used in the present invention.
이와 같이 구성된 본 발명의 작용을 더욱 상세히 설명하면 다음과 같다.Referring to the operation of the present invention configured in this way in more detail as follows.
본 발명은 예를 들어 롤러에 불균등하게 감겨있는 원단(90)을 다음공정(인쇄기, 라미네이팅, 슬리터등)으로 이송하고자할 때 적외선 센서(20)(30)를 희망위치 즉, 원단(90)의 좌우측 끝단에 고정 설치해 놓고, 항상 원단(90)의 끝부분(EDGE)이 일정한 위치에 오도록 구동부(80)를 제어하여 롤러를 좌,우 이송제어하기 위하여 사용된다.The present invention, for example, to transfer the fabric 90 unevenly wound on the roller to the next process (printer, laminating, slitter, etc.) to move the infrared sensor 20, 30 to the desired position, that is, the fabric 90 It is fixedly installed at the left and right ends of the end, and is used to control the roller left and right by controlling the drive unit 80 so that the end portion EDGE of the fabric 90 is always at a predetermined position.
즉, 원단(90)을 풀거나 감을 때 적외선 출력부(20)는 원단(90)의 끝선을 감지하기 위하여 렌즈부(10)를 거쳐 소정 범위에 적외선을 조사하고, 이 원단(90)이 일측으로 치우친 상태로 풀리면, 적외선 입력부(30)로 반사되는 적외선 반사량은 원단이 차지하는 면적에 따라 변화된다.That is, when unwinding or winding the far end 90, the infrared output unit 20 irradiates infrared rays to a predetermined range through the lens unit 10 to detect the end line of the far end 90, and the far end 90 is one side. When it is released in a biased state, the amount of infrared reflection reflected by the infrared input unit 30 changes according to the area occupied by the far-end.
따라서, 신호 증폭부(50)는 상기 적외선 입력부(20)를 통하여 입력된 신호를 증폭하고, 제어부(60)는 상기 신호 증폭부(50)로부터 증폭된 신호를 입력받아 적외선 반사량에 따라 구동부(80)의 이동위치를 복수 단계로 결정하고 이에 따른 각각의 제어신호를 설정한다.Accordingly, the signal amplifier 50 amplifies the signal input through the infrared input unit 20, and the controller 60 receives the amplified signal from the signal amplifier 50 and drives the driver 80 according to the amount of infrared reflection. ) Is determined in a plurality of stages, and each control signal is set accordingly.
여기서, 종래에는 원단(90)의 끝선을 감지하여 원단(90)의 유무만을 판단하고 그 결과를 '0'과 '1'값으로 출력하기 때문에, 원단(90)을 감거나 풀 때 원단(90)이 좌우로 흔들리게 되는 헌팅현상이 발생하였으나, 본 발명에서는 반사량에 따라 적외선이 조사되는 범위의 50%를 원단(90)이 차지할 경우가 정확한 기준위치가 되며, 이로부터 원단의 면적이 증가하거나 감소하게 되면 원단이 좌측 또는 우측으로 치우친 것으로 판단하게 된다.Here, in the related art, only the presence or absence of the fabric 90 is detected by detecting the end line of the fabric 90, and the result is output as '0' and '1', so when the fabric 90 is wound or unwound, the fabric 90 ), But the hunting phenomenon occurred to the left and right, but in the present invention, when the fabric 90 occupies 50% of the range of infrared irradiation according to the amount of reflection, the exact reference position, from which the area of the fabric increases or If it decreases, it is determined that the fabric is biased left or right.
아울러 그 비율에 따라 치우침 정도를 정밀하게 검출할 수 있다. 따라서, 제어부(60)는 상기와 같은 적외선 반사량에 따라 구동부(8)의 이동위치를 복수 단계로 결정하고 이에 따른 각각의 제어신호를 설정하는 것이다.In addition, according to the ratio, the degree of bias can be detected precisely. Therefore, the control unit 60 determines the moving position of the driving unit 8 in a plurality of steps according to the infrared reflection amount as described above, and sets the respective control signals accordingly.
이후, 신호 출력부(70)는 상기 제어부(60)의 제어신호에 의한 구동신호를 출력한다. 이에 따라 롤러가 좌우측으로 보다 정밀하게 이동되어 일측으로 치우쳐 있던 원단(90)이 정위치된 상태에서 정확하게 풀릴 수 있게 되는 것이다.Thereafter, the signal output unit 70 outputs a driving signal according to the control signal of the controller 60. Accordingly, the roller is moved more precisely to the left and right sides, so that the original fabric 90, which is biased to one side, can be accurately released in a fixed position.
이상 설명한 바와 같이 본 발명에 따른 EPC 빔 센서 장치에 의하면, 적외선 센서의 반사량에 따라 구동부의 이동위치를 복수 단계로 결정하고 이에 따른 각각의 제어신호를 출력하여 원단의 끝단을 더욱 정밀하게 제어함으로써 헌팅현상 등을 방지하고, 투명 원단의 감지와 여러색으로 인쇄되거나 반사량이 많은 원단에도 용이하게 대처하게 되는 효과가 있다.As described above, according to the EPC beam sensor device according to the present invention, the moving position of the driving unit is determined in a plurality of stages according to the reflection amount of the infrared sensor, and the respective control signals are outputted accordingly, so as to precisely control the end of the far end. It is effective to prevent the phenomenon and to easily cope with the detection of the transparent fabric and printed in multiple colors or the fabric with a large amount of reflection.
