상기한 바와 같은 선행기술들은 권취 자체를 그 목적으로 하고 있으나, 도1에 개시된 트레바샤는 보빈에 감겨지는 와이어의 길이 변화를 이용하여 수문을 여닫는 실린더나 기타 소방호스 등과 같은 피측정 대상물의 이동거리를 측정하는 측정센서로 이용되고 있다.The prior art as described above is for the purpose of the winding itself, but the travasha disclosed in Fig. 1 is a moving distance of the object to be measured, such as a cylinder or other fire hose to open the gate by using a change in the length of the wire wound on the bobbin It is used as a measuring sensor to measure.
즉, 피측정 대상물의 이동에 의해 피측정 대상물에 연결된 와이어가 보빈(105)에 감기거나 풀리게 되는데, 이때 보빈(105)의 회전중심이 되는 회전축(104)의 일측에 설치된 이동거리 연산기는 보빈(105)의 회전수 즉, 보빈(105)에 감겨지는 와이어의 길이변화를 연산하여 피측정 대상물의 이동거리를 얻는다.That is, the wire connected to the object to be measured is wound or unwound by the bobbin 105 by the movement of the object to be measured. In this case, the moving distance calculator installed at one side of the rotation shaft 104 which becomes the rotation center of the bobbin 105 may be a bobbin ( The moving distance of the object to be measured is calculated by calculating the rotation speed of 105, that is, the length change of the wire wound on the bobbin 105.
상기한 트레바샤는 회전축(104)과 나사축(103)이 타이밍 벨트(108)에 의해 연결되어 있고, 나사축(103)에는 나사축(103)의 회전에 연동해서 좌우로 이동하는 이동체(101)가 나사 결합되며, 이동체(101)에는 피측정 대상물에 연결된 와이어를 보빈(105)에 공급하기 위한 구멍(102)이 형성되어 있으므로 보빈(105)의 회전에 연동해서 이동체(101) 즉, 구멍(102)이 이동하면서 구멍(102)을 통과한 와이어가 감겨지는 위치가 조정되는 것이다.In the above-described trevasha, the rotating shaft 104 and the screw shaft 103 are connected by the timing belt 108, and the screw shaft 103 moves to the left and right in association with the rotation of the screw shaft 103. Is screwed, and the movable body 101 is formed with a hole 102 for supplying the wire connected to the object to be measured to the bobbin 105, so that the movable body 101, that is, the hole, is linked to the rotation of the bobbin 105. The position where the wire which passed the hole 102 is wound as 102 moves is adjusted.
그러나 상기한 바와 같이 이동체(101)의 구멍(102)을 통해 보빈(101)에 감겨지는 와이어의 장력이 각종 환경변화로 일정하지 유지되지 않아 보빈(101)에 감겨지는 와이어가 도2a에서와 같이 이중삼중으로 겹쳐지게 감기거나 도2b에서와 같이 서로 다른 간격으로 감기는 경우가 발생하므로 보빈(101)의 회전수와 보빈(101)에 감겨지는 와이어의 길이가 비례하지 않게 된다. 즉, 보빈(101)의 회전수와 보빈(101)에 감겨지는 와이어의 길이가 비례하지 않은 것은 피측정 대상물의 이동거리를 정확하게 측정하지 못하는 원인이 된다. 뿐만 아니라 도2a에서와 같이 와이어가 이중삼중으로 겹쳐지게 감기는 경우 와이어 간에 마찰이 발생하면서 와이어의 손상을 가져와 와이어의 수명을 단축시키는 문제점이 있다.However, as described above, the tension of the wire wound on the bobbin 101 through the hole 102 of the movable body 101 is not kept constant due to various environmental changes, so that the wire wound on the bobbin 101 is as shown in FIG. 2A. Since the double winding is repeated in threefold or winding at different intervals as in FIG. 2B, the rotation speed of the bobbin 101 and the length of the wire wound on the bobbin 101 are not proportional to each other. That is, the non-proportional ratio of the rotational speed of the bobbin 101 and the length of the wire wound on the bobbin 101 causes a failure to accurately measure the moving distance of the object to be measured. In addition, as shown in FIG. 2A, when the wire is wound to be double or triple, there is a problem in that friction occurs between the wires, resulting in damage to the wires, and shortening the life of the wires.

본 발명에 의한 트레바샤는 도4 및 도5에 도시한 바와 같이, 보빈(11) 즉, 원판 형상의 프레임(18) 중앙에 축(26)과의 분리 결합을 위한 축공(16)이 형성된 축봉(29)이 프레임(18)과 직교되게 배치되어 있는데, 이 축봉(29)의 일측에는 축공(16)을 관통하는 축(26)을 고정하기 위한 고정 척(21)이 연장되어 있다.As shown in FIGS. 4 and 5, the travsha according to the present invention has a bobbin 11, that is, a shaft having a shaft hole 16 formed therein for separation and coupling with the shaft 26 in the center of the disc-shaped frame 18. (29) is arranged orthogonal to the frame 18, and the fixing chuck 21 for fixing the shaft 26 penetrating the shaft hole 16 is extended to one side of the shaft bar 29.
이 고정척(21)은 조임쇠(22)가 결합되지 않았을 때에는 축공(16) 내로 축(26)이 원활하게 드나들 수 있는 정도의 내경을 가지지만, 조임쇠(22)가 결합된 경우에는 조임쇠(22)에 의해 조여지면서 축(26)이 축공(16) 내에서 이동하지 않도록 잡아주는 역할을 한다. 즉, 축(26)과 보빈(11)이 일체형으로 결합되어 동시에 회전하게 되는 것이다.The fixing chuck 21 has an inner diameter such that the shaft 26 smoothly enters the shaft hole 16 when the fastener 22 is not engaged, but has a fastener 22 when the fastener 22 is engaged. Tighten by 22) serves to hold the shaft 26 does not move in the shaft hole (16). That is, the shaft 26 and the bobbin 11 are integrally coupled to rotate at the same time.
이 조임쇠(22)는 고정척(21)에 끼워지는 관통공(24)이 형성된 원통 형상을 가지는 것으로서 관통공(24)의 직경을 조절할 수 있도록 조임쇠(22)의 일측에는 서로 끊어진 이격 홈(23)이 형성된 구조를 갖는다. 상기 조임쇠(22)에는 이격 홈(23)을 통과하는 나사공(28)이 형성되고, 이 나사공(28)에는 이격 홈(23)의 거리를 조절하여, 관통공(24) 더 나아가서는 축(26)이 끼워지는 축공(16)의 직경을 조절하기 위한 고정나사(25)가 체결되어 있다.The fastener 22 has a cylindrical shape in which a through hole 24 fitted into the fixing chuck 21 is formed, and the one side of the fastener 22 is separated from each other so as to adjust the diameter of the through hole 24. ) Has a formed structure. The fastener 22 is formed with a screw hole 28 passing through the separation groove 23, the screw hole 28 is adjusted to the distance of the separation groove 23, through the through hole 24 further axis A fixing screw 25 for adjusting the diameter of the shaft hole 16 into which the 26 is fitted is fastened.
여기서 고정나사(25)를 이용하여 이격 홈(23)의 간격을 조절하기 위해서는 조임쇠(22)에 형성된 나사공(28) 중 이격 홈(23) 중심으로 조정나사(25)의 진행방향의 전방에 있는 나사공에는 나사산이 형성되지만, 후방에 있는 나사공에는 나사산이 형성되지 않는다.Here, in order to adjust the spacing of the separation groove 23 by using the fixing screw 25 to the center of the separation groove 23 of the screw hole 28 formed in the fastener 22 in the front of the advancing direction of the adjustment screw 25. Threads are formed in the threaded holes, but not in the rear threaded holes.
또한 축(26)의 일측에는 보빈(11)의 회전수, 즉 보빈(11)에 감겨지는 와이어(13)의 길이를 연산하여 와이어(13)에 연결된 피측정 대상물의 이동거리를 연산하는 이동거리 연산기가 구비되어 있으며, 피측정 대상물의 이동에 연동해서 보빈(11)을 회전시켜 주는 동력원이 장착되어 있다. 물론, 동력원은 피측정 대상물의 이동거리나 보빈(11)의 회전수를 제한하는 센서에 의해 보빈(11)을 정방향 혹은 역방향으로 구동시키게 된다.In addition, the movement distance for calculating the moving distance of the object to be connected to the wire 13 by calculating the rotation speed of the bobbin 11, that is, the length of the wire 13 wound around the bobbin 11 on one side of the shaft 26 A calculator is provided, and a power source for rotating the bobbin 11 in conjunction with the movement of the object to be measured is mounted. Of course, the power source drives the bobbin 11 in the forward or reverse direction by a sensor that limits the moving distance of the object to be measured or the rotation speed of the bobbin 11.
상기 보빈(11)은 원판 형상의 프레임(18)의 외주면에 양측에 턱(20)이 형성된 일정 폭을 가지는 권취용 원통(19)가 원통 형상으로 감겨진 형상으로서 이 권취용 원통(19)의 외측에는 권취용 원통(19)의 길이방향을 따라 나선 홈(14)이 형성되어 있다.The bobbin 11 is a shape in which a winding cylinder 19 having a predetermined width in which a jaw 20 is formed at both sides on an outer circumferential surface of a disk-shaped frame 18 is wound in a cylindrical shape. The spiral groove 14 is formed in the outer side along the longitudinal direction of the winding cylinder 19. As shown in FIG.
여기서 보빈(11)의 권취용 원통(19)에 형성된 나선 홈(14)은 마모가 적고 일정한 이격거리를 가지는 사각 나선 홈으로서 나선 홈(14)의 폭(d1)과 이와 교차지게 배치된 나선 돌기(15)의 폭(d2)은 동일하다. Here, the spiral groove 14 formed in the winding cylinder 19 of the bobbin 11 is a square spiral groove having less wear and having a predetermined separation distance, and the spiral protrusion 14 disposed to intersect with the width d1 of the spiral groove 14. The width d2 of 15 is the same.
물론, 그의 양단이 보빈(11)과 피측정 대상물에 고정된 상태에서, 보빈(11)에 감겨지는 와이어(13)의 직경은 나선 홈(14)의 폭(d1)이나 나선 돌기(15)의 폭(d2)의 2배보다는 작다.Of course, in a state where both ends thereof are fixed to the bobbin 11 and the object to be measured, the diameter of the wire 13 wound on the bobbin 11 is equal to the width d1 of the spiral groove 14 or the spiral protrusion 15. Less than twice the width d2.
또한 보빈(11)의 권취용 원통(19)의 나선 홈(14)에는 너트 링(12)이 나사 결합되어 있는데, 이 너트 링(12)은 외줄 또는 두 줄 이상의 너트 링으로서 보빈(11)의 회전에 따라 나선 홈(14)을 타고 보빈(11) 즉, 권취용 원통(19)의 좌우로 이동하게 된다.In addition, a nut ring 12 is screwed into the spiral groove 14 of the winding cylinder 19 of the bobbin 11, which is a nut or two or more rows of nut rings of the bobbin 11. In accordance with rotation, the spiral groove 14 is moved to the left and right of the bobbin 11, that is, the winding cylinder 19.
상기 너트 링(12)의 일측에는 이동거리 측정을 위한 피측정 대상물에 연결된 와이어(13)의 이동을 유도하기위한 유도관(17)의 일측이 고정되어 있고, 이 유도관(17)의 타측은 와이어(13)가 들어오는 방향을 향하도록 배치되어 있다. 다시 말해, 너트 링(12) 한 지점에 유도관(17)이 접선을 이루도록 부착되는 것이다. 이때 와이어(13)가 유입되는 방향을 향하는 유도관(17)의 타측이 허공이 떠 있어 너트 링(12)과 유도관(17)의 결합관계가 견고하지 못하므로 지지대(27)를 이용하여 유도관(17)을 너트 링(12)에 다시 한번 고정한다.One side of the nut ring 12 is fixed to one side of the induction pipe 17 for inducing the movement of the wire 13 connected to the object to be measured for moving distance measurement, the other side of the induction pipe 17 It is arrange | positioned so that the wire 13 may face the incoming direction. In other words, the guide pipe 17 is attached to form a tangent to the nut ring 12. At this time, the other side of the induction pipe 17 facing the direction in which the wire 13 flows into the air so that the coupling relationship between the nut ring 12 and the induction pipe 17 is not firm, so it is guided using the support 27. Secure the tube (17) to the nut ring (12) once again.
특히, 도면에서 보이는 바와 같이 너트 링(12)은 하나의 폐루프로 형성할 수도 있으나, 보빈(11)의 권취용 원통(19)에 수월하게 분리 결합하기 위해 한 지점이 끊어진 형상을 가지는데, 이는 권취용 원통(19)의 나선 홈(14)에 감겨지는 와이어(13)를 보다 정확한 위치로 안내하기 위함이다.In particular, as shown in the figure, the nut ring 12 may be formed as one closed loop, but has a shape where one point is broken to easily separate and couple the winding cylinder 19 of the bobbin 11, This is for guiding the wire 13 wound on the spiral groove 14 of the winding cylinder 19 to a more accurate position.
즉, 끊어진 너트 링(12)의 단부에 유도관(17)의 단부가 위치하도록 너트 링(12)과 유도관(17)이 결합되어 있으므로 권취용 원통(19)의 나선 홈(14)과 유도관(17)과의 거리를 최소한으로 줄일 수 있다.That is, since the nut ring 12 and the guide pipe 17 are coupled so that the end of the guide pipe 17 is positioned at the end of the broken nut ring 12, the spiral groove 14 of the winding cylinder 19 is guided. The distance from the pipe 17 can be reduced to a minimum.
바람직하게는 보빈(11)의 회전에 따라 너트 링(12) 즉, 유도관(17)이 향하는 방향이 조금씩 변경되므로 이에 맞게 와이어(13)의 유입방향도 함께 조절하는 것이 당연하다. Preferably, the direction in which the nut ring 12, that is, the induction pipe 17, is slightly changed according to the rotation of the bobbin 11, so that the inflow direction of the wire 13 is also adjusted accordingly.
따라서, 도6 및 도7에서와 같이 동력원에 의한 보빈(11)의 회전으로 인해 너트 링(12)이 권취용 원통(19)에 형성된 첫번째 나선 홈(14a)을 타고 이동하는 동안 유도관(17)을 타고 들어오는 와이어(13)가 권취용 원통(19)의 첫번째 나선 홈(14a)에 감겨지게 된다.Thus, as shown in Figs. 6 and 7, the induction pipe 17 is moved while the nut ring 12 moves on the first spiral groove 14a formed in the winding cylinder 19 due to the rotation of the bobbin 11 by the power source. The wire 13 coming in) is wound on the first spiral groove 14a of the winding cylinder 19.
계속해서, 너트 링(12)이 두번째, 세번째 나선 홈(14b)(14c)을 타고 이동하는 동안에는 유도관(17)을 타고 들어오는 와이어(13)가 두번째, 세번째 나선 홈(14b)(14c)에 감겨지므로 보빈(11)에 감겨지는 와이어(13)의 간격이 일정하게 유지된다. 위와 같은 동작은 보빈(11)의 회전하는 동안 반복적으로 일어난다.Subsequently, while the nut ring 12 moves in the second and third spiral grooves 14b and 14c, the wire 13 coming into the guide tube 17 is connected to the second and third spiral grooves 14b and 14c. Since it is wound, the space | interval of the wire 13 wound by the bobbin 11 is kept constant. The above operation occurs repeatedly during the rotation of the bobbin 11.
즉, 보빈(11)이 한 바퀴씩 회전할 때마다 동일한 길이의 와이어(13)가 보빈(11)에 감기게 되므로 도시되지 않은 이동거리 연산기는 보빈(11)의 회전수를 분석하여 와이어(13)의 길이 즉, 피측정 대상물의 이동거리를 정확하게 측정할 수 있는 것이다.That is, each time the bobbin 11 rotates by one turn, the wire 13 having the same length is wound on the bobbin 11, so that the moving distance calculator (not shown) analyzes the rotational speed of the bobbin 11 to determine the wire 13. ), That is, the moving distance of the object to be measured can be accurately measured.
뿐만 아니라, 본 발명은 보빈(11)에 감겨지는 와이어(13)가 이중삼중으로 겹쳐지면서 감기지 않으므로 와이어(13) 즉, 피측정 대상물의 이동거리 측정오차가 발생하지 않을뿐더러 와이어(13) 간의 마찰이 발생하지 않아 와이어(13)의 수명을 연장할 수 있다.In addition, in the present invention, since the wire 13 wound on the bobbin 11 does not wind while being overlapped in a double triple, the wire 13, that is, the movement distance measurement error of the object to be measured does not occur, and the friction between the wires 13 occurs. This does not occur and can extend the life of the wire 13.
