본 고안은 실절단검지장치, 더 상세하게는 보빈(bobbin)등으로 부터 인출한 실을 회전로울러의 둘레면에 접촉되게 주행시키고, 실의 절단이 생겼을 경우에 변화하는 회전로울러의 원주속도 변화에 대응하여 실절단을 검지하도록한 실절단검지장치의 개량에 관한 것이다.The present invention drives a thread drawn from a thread cutting detection device, more specifically, bobbin, etc., in contact with the circumferential surface of the rotary roller, and changes the circumferential speed of the rotary roller that changes when the thread is cut. The present invention relates to an improvement of a thread breaking detection device which correspondingly detects a thread break.
종래의 실절단검지장치를 제2도 및 제3도에 도시한다. 도면에서 부호 1은 지지기판, 2는 이 지지기판에 고정부착된 하우징, 5는 하우징(2)내에 장착된 한쌍의 베어링(3)(4)에 의해서 회전자유롭게 축지(軸支)된 회전축으로서, 이 회전축의 양단에는 회전축과 일체로 회전하는 회전로울러(6)와 검지판(7)이 회전가능하게 고정되어 있다.The conventional thread breaking detection apparatus is shown in FIG. 2 and FIG. In the drawing, reference numeral 1 denotes a support substrate, 2 a housing fixedly attached to the support substrate, and 5 a rotation shaft freely rotatable by a pair of bearings 3 and 4 mounted in the housing 2, At both ends of the rotary shaft, the rotary roller 6 and the detection plate 7 which are integrally rotated with the rotary shaft are rotatably fixed.
회전로울러(6)는 그 전둘레 가장자리에 V형홈(6a)이 형성되어 있으며, 상기 지지기판(1)에 실가이드(10)(11)에 의해 안내되는 실(Y)은 이 V형홈(6a)에 끼워져 접촉하면서 주행하는 것에 의해, 회전로울러(6)를 한쪽방향으로 회전(회전축(5) 및 검지판(7)도 일체로 회전한다)시킨다.The rotary roller 6 has a V-shaped groove 6a formed at the front edge thereof, and the seal Y guided by the seal guides 10 and 11 on the support substrate 1 is the V-shaped groove 6a. ), The rotary roller 6 is rotated in one direction (the rotary shaft 5 and the detection plate 7 also rotate integrally).
또 검지판(7)에는 그 외주쪽으로 1개의 작은 구멍(7a)이 형성되어 있으며, 그리고 이 작은 구멍(7a)에 대응하는 위치에는 센서(12)가 배치되어 있다.Moreover, one small hole 7a is formed in the outer periphery of the detection plate 7, and the sensor 12 is disposed at a position corresponding to the small hole 7a.
종래의 실절단검지장치는 상술한 바와 같이 구성된 것으로서, 화살표방향으로 주행하는 실(Y)의 접촉에 의해 회전하는 회전로울러(6)와 같이 회전하는 검지판(7)의 작은 구멍(7a)을 센서(12)로 검출하고, 이 검출신호를 예를들면 펄스파형으로 변환하여, 제어장치에 출력하도록 구성한 것으로서, 실이 절단되었을 경우, 회전로울러(6)의 원주속도의 저하에 따라서 정상시에 일정하게 연속적으로 발생하고 있는 회전출력신호, 즉 펄스파형은 불연속적인 펄스파형으로 되며, 이 신호를 적당한 출력소자를 개재하여 실절단신호로서 검출하도록 한 것이다.The conventional thread cutting detection device is configured as described above, and the small hole 7a of the detection plate 7 that rotates like the rotary roller 6 that rotates by the contact of the yarn Y traveling in the direction of the arrow is formed. It is configured to detect by the sensor 12 and convert this detection signal into a pulse waveform, for example, and output it to the control device. When the thread is cut, it is normal in accordance with the decrease in the circumferential speed of the rotary roller 6. The rotational output signal, that is, the pulse waveform, which is continuously generated continuously, becomes a discontinuous pulse waveform, and the signal is detected as a real cut signal through an appropriate output element.
따라서, 이와 같은 종래의 실절단검지장치에 있어서는, 회전로울러(6)를 항상 가볍고 원활하게 회전하도록 구성하는 것이 절대조건으로 된다.Therefore, in such a conventional thread cutting detection apparatus, it is an absolute condition that the rotating roller 6 is configured to rotate at all times lightly and smoothly.
그런데 종래의 장치는 제2도에 도시한 바와 같이 하우징(2)의 끝면에 베어링(3)이 배치되어 있으며, 이 베어링(3)에 밀착상태로 회전로울러(6)가 배치된 구조로 되어 있기 때문에, 실의 주행시에 이 실에 부착된 먼지나 솜털이 제2도의 A부에 서서히 축적되어, 이것에 의해 베어링(3)의 회전이 무겁게 된다.However, in the conventional apparatus, as shown in FIG. 2, the bearing 3 is arranged on the end face of the housing 2, and the rotary roller 6 is arranged in close contact with the bearing 3. For this reason, the dust and the hairs which adhered to this thread at the time of running of a thread accumulate gradually in the A part of FIG. 2, and the rotation of the bearing 3 becomes heavy by this.
또, 회전로울러(6)에 접촉하여 주행하는 실이 이 회전로울러에서 탈락했을 경우, 이 탈락한 실은 제2도의 A부에 끼워진 상태로 주행하고, 그곳에 축적된 먼지나 솜털이 이 실에 의해 압축된다. 그리고 이와 같이 축적된 먼지나 솜털이 압축되면, 베어링(3)의 회전은 다시 무겁게 되며, 그 결과 회전로울러(6)를 정상적인 상태로 회전시킬 수 없게 되어 실절단검지의 오동작이나 오검지를 초래하는 원인으로 되고 있다.When the thread traveling in contact with the rotary roller 6 falls out of the rotary roller, the dropped thread travels in the state fitted in the A part of FIG. 2, and the dust and the hair accumulated therein are compressed by the thread. do. When the accumulated dust or down is compressed, the rotation of the bearing 3 becomes heavy again, and as a result, the rotation roller 6 cannot be rotated in a normal state, which causes malfunction or misdetection of the thread cutting detection. It is the cause.
본 고안의 과제는 상기와 같은 문제점을 해결하기 위하여 된 것으로서, 주행하는 실에 부착된 먼지나 솜털이 축적되어도 베어링을 항상 가볍게 회전시켜 회전로울러를 정상적인 상태로 회전시키도록 구성한 실절단검지장치를 제공하는 것을 목적으로 하고 있다.The problem of the present invention is to solve the above problems, and provides a thread cutting detection device configured to rotate the rotary roller in a normal state by always rotating the bearing lightly even when dust or fuzz accumulated on the running thread is accumulated. It is aimed at.
상기와 같은 과제를 해결하기 위해, 본 고안은 하우징의 한쪽끝을 베어링의 끝면보다 바깥쪽으로 연장하여 방진벽을 설치하는 한편 베어링과 회전로울러를 서로 뻗어진 상태로 배치시켜서, 방진벽내를 공간부로서 구성한 것이다.In order to solve the above problems, the present invention extends one end of the housing outward than the end surface of the bearing to install a dustproof wall, while arranging the bearing and the rotating roller in an extended state, thereby forming the inside of the dustproof wall as a space part. will be.
이하, 본 고안의 실시예를 첨부도면에 의거하여 설명한다.Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.
제1도에서, 부호 1은 지지기판, 2는 이 지지기판에 고정부착된 하우징, 5는 하우징(2)내에 장착된 한쌍의 베어링(3)(4)에 의해 회전자유롭게 축지된 회전축이며, 이 회전축의 양단에는 이 회전축과 일체로 회전하는 회전로울러(6)와 검지판(7)이 회전가능하게 부착되어 있다.In Fig. 1, reference numeral 1 denotes a support substrate, 2 a housing fixedly attached to the support substrate, and 5 a rotation shaft freely rotatable by a pair of bearings 3 and 4 mounted in the housing 2, Both ends of the rotating shaft are rotatably attached to the rotating roller 6 and the detection plate 7 which rotate integrally with the rotating shaft.
회전로울러(6)는 그 전둘레가장자리에 V형홈(6a)이 형성되어 있으며, 지지기판(1)에 설치된 실가이드(10)(11)에 의해 안내되는 실(Y)은 이 V형홈(6a)에 끼워져 접촉하면서 주행하는 것에 의해, 회전로울러(6)를 한쪽방향으로 회전시킨다. 또 검지판(7)에는 그 외주쪽으로 1개의 작은 구멍(7a)이 형성되어 있으며, 그리고 이 작은 구멍(7a)에 대응하는 위치에는 센서(12)가 배치되어 있다.The rotary roller 6 has a V-shaped groove 6a formed at the front edge thereof, and the thread Y guided by the seal guides 10 and 11 provided on the support substrate 1 is the V-shaped groove 6a. The rotary roller 6 is rotated in one direction by being driven while being in contact with each other. Moreover, one small hole 7a is formed in the outer periphery of the detection plate 7, and the sensor 12 is disposed at a position corresponding to the small hole 7a.
상기 하우징(2)의 한쪽끝, 즉 베어링(3)을 장착한 축을 이 베어링(3)의 끝면보다 바깥쪽으로 연장하고, 이 연장부분을 방진벽(2a)으로 구성함과 동시에, 회전축(5)상에서 상기 베어링(3)과 회전로울러(6)를 서로 떨어진 상태로 배치하고, 상기 방진벽(2a)내를 공간부(8)로 형성한다.One end of the housing 2, i.e., the shaft on which the bearing 3 is mounted, extends outward from the end surface of the bearing 3, and the extension part is constituted by the anti-vibration wall 2a, and on the rotating shaft 5 The bearing 3 and the rotary roller 6 are arranged to be separated from each other, and the inside of the dustproof wall 2a is formed as a space 8.
이상과 같이 본 고안에 의하면, 하우징의 한쪽끝을 방진벽으로 구성함과 동시에, 그 내부를 공간부로 형성하는 것에 의해, 회전로울러에 접촉하여 주행하는 실에 부착된 먼지나 솜털은 직접 베어링이나 회전로울러의 둘레에 축적되는 일이 없고, 이 결과 회전로울러를 항상 정상적인 상태로 회전시킬 수 있는 것으로서, 실절단검지의 오동작이나 오검지를 해소할 수가 있는 것이다.As described above, according to the present invention, by forming one end of the housing as a dustproof wall and forming the inside thereof as a space part, the dust and the fuzz adhering to the thread traveling in contact with the rotating roller are directly bearing or rotating roller. As a result, the rotary roller can always be rotated in a normal state, and the malfunction and detection of the broken cutting detection can be eliminated.
