Description

섬유직기의 절단된 경사 감지시스템{Cutting slant sensor system of fiber loom}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

본 발명은 섬유직기의 절단된 경사 감지시스템에 관한 것으로서 더욱 상세하게는 직물을 직조하는 과정에서 절단된 경사와 풍면을 정확하게 선별하여 절단된 경사만을 감지하여 섬유직기를 정지시킬 수 있도록 구성된 섬유직기의 절단된 경사 감지시스템에 관한 발명이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut slope detection system for a textile loom, and more particularly, to a textile loop loom which is configured to precisely select slopes and wind- The present invention relates to a cut slope detection system.

주지하는 바와 같이 섬유직기에서 직물을 직조하기 위하여 경사빔에 권취된 경사가 헬드프레임의 상하왕복에 의한 개구작용으로 개구되게 하고 개구된 경사 사이로 위사를 공급하고 바디침 작용을 반복하게 되며 이러한 작용으로 직물이 직조되는 것이다.As is known, in order to weave a fabric in a textile loom, the warp wound on the warp beam is made to open by the opening action of the reciprocating upward and downward movement of the heddle frame, the weft is fed between the opened warp yarns, The fabric is weaved.

상기와 같이 섬유직기에서 직물을 직조하는 과정에서 여러 가지 부적절한 조건에 의해서 경사의 절단이 생기게 되며 상기와 같이 경사가 절단된 상태로 직물을 직조하게 되면 절단된 경사 부분이 직물에 결함이 되므로 절단된 경사를 신속하게 감지하여 직물이 직조되는 것을 정지시키는 장치가 섬유직기에 설치되어 있다. As described above, in the process of weaving a fabric in a textile loom, various inconvenient conditions cause the incline to be cut. When the fabric is weaved with the incline cut as described above, the incised portion is defective in the fabric, A device for quickly detecting the warp and stopping the weaving of the fabric is provided in the fabric loom.

상기와 같이 경사의 절단을 감지하여 섬유직기를 정지시키는 장치는 기계식 드롭퍼, 와인더드롭퍼 등의 장치가 있다.The apparatus for stopping the fiber loom by detecting the cutting of the warp yarns as described above includes a mechanical dropper and a winder dropper.

상기의 기계식 드롭퍼는 오래전부터 널리 사용되어온 장치이고 신뢰성도 비교적 높은 편이나 제직을 준비하는 공정에서 각각의 경사마다 드롭핀을 일일이 걸어주어야 하므로 준비공정에서 번거로움이 있다.The mechanical dropper is a device widely used for a long time and has a relatively high reliability. However, since the drop pins have to be individually hooked at each slope in the step of preparing the weaving, there is a complication in the preparation process.

상기와 같은 기계식 드롭퍼의 단점을 보완하기 위하여 와인더드롭퍼가 개발 사용되고 있으나, 구조적으로 섬유직기의 동력을 이용하여 와인더드롭퍼를 회전시키면서 와인더드롭퍼를 구성하는 브러쉬를 이용하여 경사를 브러쉬로 빗질하여 브러쉬에 걸린 절단된 경사를 브러쉬가 감고 회전하는 것을 센서가 감지하는 것으로 절단된 경사를 감지하게 되는데, 절단된 경사를 감지하는 속도가 늦고, 경사를 절단시키는 원인을 제공하기도 하는 단점이 있다.In order to compensate for the disadvantages of the mechanical dropper as described above, a winder dropper has been developed and used. However, the winder dropler is structurally rotated by using the power of the fiber loom, and a brush constituting the winder dropper is used to combine the inclination with a brush The sensor senses that the brush is wound around the cut slope caught by the brush and detects that the brush is rotated. However, the speed of detecting the slope is slow and the cause of cutting the slope is also provided.

상기의 기계식 드롭퍼와 와인더드롭퍼의 단점을 보완하여 경사를 감지하는 장치로는 섬유직기의 일측에는 적외선을 발생시키는 투광센서를 타일측에는 적외선을 수광하는 수광센서를 설치하여 경사가 절단되어 자중에 의해 낙하되면 투광센서에서 수광센서로 적외선이 수광되는지 여부에 따라 절단된 경사를 감지할 수 있게 구성되어 있으나 절단된 경사와 날아다니는 풍면을 정확하게 선별하지 못하고 센싱되는 경우가 빈번하게 발생하여 오동작으로 인한 섬유직기의 정지로 섬유직기의 가동시간 단축과 그 오동작 해소 조치에 따른 섬유직기의 가동중단으로 인하여 생산성이 떨어지는 등의 문제점이 있다.As a device for detecting the inclination by compensating for the disadvantages of the mechanical dropper and the winder dropper, a light sensor for generating infrared rays is installed on one side of the fiber loom, and a light receiving sensor for receiving infrared rays is disposed on the tile side. When falling, it is configured to detect the incline cut according to whether the infrared light is received by the light-receiving sensor or the light-receiving sensor. However, it is frequently detected that the cut incline and flying air can not be precisely selected, There is a problem in that the productivity is lowered due to the shortening of the running time of the loom of the loom due to the stop of the loom and the stoppage of the loom of the loom due to the measures for eliminating the malfunction.

본 발명에 의한 섬유직기의 절단된 경사 감지시스템은 섬유직기의 경사가 개구되는 경사 개구부 양쪽에 투광측 프레임(10)과 수광측 프레임(11)을 설치하고 상기 투광측 프레임(10)에 3개의 투광센서(1)(2)(3)를 설치하고, 수광측 프레임(11)에 3개의 수광센서(1')(2')(3')를 상호 대응되어 투수광되도록 설치하며,In the cut tilting detection system of the fiber loom according to the present invention, the light-transmitting side frame (10) and the light-receiving side frame (11) are provided on both sides of the inclined opening where the warp of the fiber loom is opened, The three light receiving sensors 1 ', 2', and 3 'are provided on the light receiving side frame 11 so as to be mutually correspondingly received and transmitted,

상기 투수광센서 사이에서 경사와 풍면을 정확하게 선별할 수 있도록 센터에 있는 투광센서(2)와 전,후에 있는 투광센서(1)(3)는 간격이 10밀리가 되게 하고, 대응하는 위치에 센터에 있는 수광센서(2')와 전,후에 수광센서(1')(3')의 간격도 10밀리가 되게 설치되며,In order to precisely select the inclination and the airsurface between the light-receiving-light sensors, the light-projecting sensor 2 and the light-projecting sensors 1 and 3 before and after the center are spaced apart by 10 mm, The distance between the light-receiving sensor 2 'and the light-receiving sensor 1' or 3 'before and after the light-receiving sensor 2' is 10 mm,

상기 3개의 투광센서와 3개의 수광센서는 콘트롤박스(20)에 설치된 CPU에 연결되고, 섬유직기의 경사 개구시간을 체크하기 위해 섬유직기에 설치된 엔코더(21)와 3개의 투광센서와 3개의 수광센서의 감도조절을 위한 감도조절기(22)와 투광과 수광 시간을 조절하기 위한 타이머(23)를 CPU에 연결하여 구성된 것이다.The three light projecting sensors and the three light receiving sensors are connected to a CPU installed in the control box 20 and are provided with an encoder 21 installed in a textile loom, A sensitivity adjuster 22 for adjusting the sensitivity of the sensor and a timer 23 for adjusting the light emission and the light reception time are connected to the CPU.

상기한 본 발명에 의한 섬유직기의 절단된 경사 감지시스템에 관한 작용을 살펴보면 다음과 같다.The operation of the cut slant detection system of the fiber loom according to the present invention will be described as follows.

섬유직기에서 경사의 개구와 위사의 위입이 반복되면서 직물을 직조하는 과정에서 경사가 개구되면, 그 개구된 시점을 섬유직기에 설치된 엔코더(21)가 캐치하여 직물을 직조하는데 정보를 제공하는 작용을 하고 있으며, 이러한 작용은 일반적인 것이므로 구체적인 설명은 생략한다.When the warp is opened in the process of weaving the fabric while the opening of the warp yarn and the weft insertion are repeated in the weaving machine, the encoder 21 installed at the weaving machine catches the opening time of the warp yarn to provide information for weaving the weaving Since these operations are general, a detailed description is omitted.

상기와 같이 섬유직기에서 경사(55)의 개구와 위사의 위입이 반복되면서 직물을 직조하는 과정에서 경사가 개구되면 그 신호를 본 발명을 구성하는 콘트롤박스(20)에 내장된 CPU에 보낸다.As described above, when the warp is opened in the process of weaving the fabric while the opening of the warp thread 55 and the weft insertion are repeated in the weaving machine, the signal is sent to the CPU built in the control box 20 constituting the present invention.

그러면, CPU에서 3개의 투광센서(1)(2)(3)와 3개의 수광센서(1')(2')(3')를 작동시켜 적외선(54)이 상호 투수광 되게 하며, 반대로 경사의 개구가 폐쇄되면, 그 신호를 섬유직기에 설치된 엔코더(21)가 캐치하여 콘트롤박스에 내장된 CPU에 신호를 보내 3개의 투광센서(1)(2)(3)와 3개의 수광센서(1')(2')(3')의 작동을 정지시키며 이러한 작용을 반복하게 된다.Then, the CPU causes the three light projecting sensors 1, 2, 3 and the three light receiving sensors 1 ', 2', 3 'to operate so that the infrared rays 54 are mutually transmitted and received, The encoder 21 installed in the loom catches the signal and sends a signal to the CPU incorporated in the control box to transmit the signal to the three light-projecting sensors 1, 2, 3 and the three light-receiving sensors 1 ') (2') and (3 '), and repeats this operation.

상기와 같이 경사(55)가 개구되는 순간에 3개의 투광센서와 3개의 수광센서가 작동을 반복하면서 직물을 직조하게 되는데, 이러한 직조과정에서 경사가 절단되고 상기와 같이 경사가 절단된 상태에서 경사가 개구되면 3개의 투광센서(1)(2)(3)와 3개의 수광센서(1')(2')(3')에서 절단된 경사를 감지하여 섬유직기의 작동을 정지시키는 것이다.As described above, at the moment when the warp 55 is opened, the three light projecting sensors and the three light receiving sensors are repeatedly operated to weave the fabric. In this weaving process, the warp is cut, 2, 3 'and 3 light receiving sensors 1', 2 ', 3', the operation of the fiber loom is stopped by sensing the slope cut off from the three light projecting sensors 1, 2, 3 and the three light receiving sensors 1 ', 2', 3 '.

그런데, 상기 3개의 투광센서(1)(2)(3)와 3개의 수광센서(1')(2')(3')들은 10밀리 간격으로 설치되어 있기 때문에 3개의 투광센서(1)(2)(3)와 3개의 수광센서(1')(2')(3')들 중에 투수광센서 2개 이상 즉, 투수광센서(1)(1')(2)(2')에서 동시에 적외선이 차단되면 섬유직기의 작동을 정지시킨다.Since the three light projecting sensors 1, 2 and 3 and the three light receiving sensors 1 ', 2' and 3 'are arranged at intervals of 10 millimeters, the three light projecting sensors 1 (2 '), (2'), and (3 ') of the three light receiving sensors 1', 2 ' At the same time, when the infrared ray is interrupted, the operation of the fiber loom is stopped.

따라서, 날아다니는 풍면의 경우에 투수광 센서 2개 이상에서 적외선을 차단시킬 수 없기 때문에 풍면과 절단된 경사를 정확하게 선별할 수 있는 것이다.Therefore, in the case of the flying airspeed, it is not possible to block the infrared rays from two or more of the penetrating light sensors, so that the airspeed and the cut slope can be accurately selected.

그리고, 섬유직기에서 직물을 직조할 때, 경사의 굵기에 따라서 투광센서에서 발사되는 적외선의 강도를 조절하는데, 이때의 감도조절기(51)를 작동시켜 CPU를 통해서 조절하며, 또 경사의 개구시간에 따라 투광센서에서 발사되는 적외선의 시간을 조절하는데, 이때 타이머(52)를 작동시켜 CPU를 통해 조절하게 된다.When fabric is woven in a textile loom, the intensity of the infrared rays emitted from the light projecting sensor is adjusted according to the thickness of the inclination. The sensitivity adjuster (51) is operated to adjust the intensity through the CPU, Accordingly, the timer of the infrared ray emitted from the light emitting sensor is adjusted, and the timer 52 is operated to control the infrared ray through the CPU.
