본 발명은 관수용 튜브의 배수홀 천공장치에 관한 것으로 특히 제이저빔에 의해 홀을 천공하여 튜브의 수명을 연장시킬 수 있는 관수용 튜브의 배수홀 천공장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage hole drilling apparatus for a watering tube, and more particularly, to a drainage hole drilling apparatus for a watering tube that can extend the life of a tube by drilling a hole by a jitter beam.

종래의 관수용 튜브의 배수홀 천공장치는 첨부도면 제1도에 도시한 바와 같이 튜브(1') 상면을 핀(100)으로 물리적인 힘을 가하여 배수홀(11')을 천공하는 것으로 이는 배수홀(11') 주변이 물리적인 힘의 충격으로 많은 크랙(crack)이 발생되어 수압에 취약하여 배수관의 수명이 단축되는 문제점이 있었다.As shown in FIG. 1 of the accompanying drawings, a conventional drainage hole drilling tube is used to drill the drainage hole 11 'by applying a physical force to the upper surface of the tube 1' with the pin 100. Many cracks are generated due to the impact of physical force around the hole 11 ', which is vulnerable to water pressure, thereby shortening the life of the drain pipe.

본 발명은 상기한 종래의 결점을 감안하여 이루어진 것으로 이송되는 튜브에 레이저빔을 조사하여 배수홀을 턴공할 수 있게 한 장치를 제공하는데 목적을 둔 것이다.The present invention has been made in view of the above-mentioned drawbacks of the prior art, and an object thereof is to provide a device capable of turning a drain hole by irradiating a laser beam to a tube to be transported.

상기한 목적을 달성하기 위하여 본 발명은 구동모터에 의해 회전하는 캡스턴 롤에 의해 풀림롤에서 감김롤쪽으로 이송되는 관수용 튜브 상면에, 공진기에서 조사된 레이저빔을 다각형의 반사미러를 통해 일정시간동안 레이저빔을 조사시켜 배수홀을 천공할 수 있게 한 것으로 이를 첨부된 도면에 의거하여 보다 상세히 설명하면 다음과 같다.In order to achieve the above object, the present invention provides a laser beam irradiated from a resonator for a predetermined time through a polygonal reflection mirror on the upper surface of the irrigation tube which is transferred from the unwinding roll to the winding roll by a capstan roll rotated by a drive motor. The laser beam is irradiated to allow drilling of the drainage hole, which will be described in detail with reference to the accompanying drawings.

도면 제2도에 도시한 바와 같이 구동모터(4)에 의해 회전하는 캡스턴 롤(41)에 의해 관수용 튜브(1)가 풀림롤(2)에서 감김롤(6)측으로 지지롤러(3)에 지지되도록 이송되게 설치하고, 공진기(200)에서 조사되는 레이저빔(201) 이 접속렌즈(9) 및 반사미러(8)를 통해 구동모터(5)에 의해 회전하는 다각형의 반사미러(7)에 반사되어 상기 이송되는 튜브(1)의 상면에 일정시간 주사되도록 설치 구성하였다.As shown in FIG. 2, the water-filling tube 1 is moved from the unwinding roll 2 to the winding roll 6 side by the capstan roll 41 which is rotated by the drive motor 4. It is installed to be transported to be supported, and the laser beam 201 irradiated from the resonator 200 is applied to the reflection mirror 7 of the polygon rotated by the driving motor 5 through the connection lens 9 and the reflection mirror 8. The reflection was configured to be scanned for a predetermined time on the upper surface of the tube 1 to be transferred.

이와 같이 구성되는 본 발명은 구동모터(4)의 회전에 의해 캡스턴롤(41)이 관수용 튜브(1)를 풀림롤(2)에서 감김롤(6)쪽으로 일정속도를 가지게 이송시키고 공진기(200)로부터 발산되는 레이저빔(201)이 반사미러(8)에 의해 반사되며 접속렌즈(9)를 통과한후 다시 반사미러(8)에 의해 반사굴절되어 구동모터(50에 의해 회전하는 다각형의 반사미러(7)에 레이저빔(201)이 조사된다.According to the present invention configured as described above, the capstan roll 41 transfers the watering tube 1 from the unwinding roll 2 to the winding roll 6 by the rotation of the driving motor 4 at a constant speed and resonator 200. The laser beam 201 emitted from the beam is reflected by the reflecting mirror 8 and passes through the connecting lens 9, and is then refracted by the reflecting mirror 8 to reflect the polygon rotated by the driving motor 50. The laser beam 201 is irradiated to the mirror 7.

이때 다각형의 반사미러 회전속도는 관수용 튜브(1)를 이송시키는 캡스턴롤(41)의 회전속도와 동기되도록 셋팅하여 다각형의 반사미러(7)에 의해 반사되는 레이저빔(201)이 지지롤러(3)상을 통과하는 관수용 튜브(1) 상면을 일정시간동안 추적하며 조사하여 배수홀(11)을 천공할 수 있는 것이다.At this time, the rotation speed of the reflection mirror of the polygon is set to be synchronized with the rotation speed of the capstan roll 41 for transporting the watering tube 1 so that the laser beam 201 reflected by the reflection mirror 7 of the polygon is supported by the support roller ( 3) to track the upper surface of the watering tube (1) passing through the phase for a predetermined time to be able to drill the drainage hole (11).

상기의 구동모터(4, 5)의 동기는 주지의 방식인 구동모터간에 엔코더가 설치되어 있어, 이 엔코더의 검출신호를 입력받아 모터속도를 전자적으로 제어하는 제어기에 의해 두 구동모터(4, 5)의 속도를 동일하게 제어하게 할 수 있으며, 경우에 따라서는 하나의 모터로써 무단변속기를 사용할 수 있다.In the synchronization of the drive motors 4 and 5, encoders are provided between the drive motors, which are well-known methods, and the two drive motors 4 and 5 are controlled by a controller which receives the detection signal of the encoder and electronically controls the motor speed. Speed can be controlled equally, and in some cases, a continuously variable transmission can be used as a motor.

한편, 레이저빔(201)에 의해 천공된 배수홀(11)은 도면 제3도에 도시한 바와 같이 배수홀(11) 주변이 레이저빔(201)에 의해 녹은 재질이 도우넛형의 돌기부(12)를 형성하여 수압에 대한 내구성을 증대시킬 수 있다.Meanwhile, as illustrated in FIG. 3, the drain hole 11 drilled by the laser beam 201 may have a doughnut-shaped protrusion 12 having a material melted by the laser beam 201 around the drain hole 11. Forming can increase the durability against water pressure.

그리고 가공거리조절은 촛점거리조정 방식으로 다른 촛점거리를 가지는 렌즈를 부착했을때 촛점면의 위치를 지지롤러(3)의 경사위치를 조절하여서 이룰수 있다.And the processing distance adjustment can be achieved by adjusting the inclination position of the support roller (3) the position of the focal plane when a lens having a different focal length is attached by the focal length adjustment method.

이와 같이 구성되고 작동되는 본 발명은 관수용 튜브가 일정속도로 진행되는 동안 배수홀을 천공하므로 배수홀의 직경과 간격이 일정하게 천공되어 제품의 품질을 향상시킬 수 있을뿐 아니라 레이저빔에 의해 녹은 재질이 배수홀 주변을 보강시키는 역활을 하여 수압에 취약한 배수홀의 내구성을 크게 증대시킬 수 있는 아주 특출한 장치의 발명인 것이다.The present invention constructed and operated as described above drills the drainage hole while the watering tube proceeds at a constant speed, so that the diameter and spacing of the drainage hole are constantly drilled to improve the quality of the product as well as the material melted by the laser beam. It is the invention of a very special device that can act to reinforce the periphery of the drainage hole and greatly increase the durability of the drainage hole vulnerable to water pressure.
