본 발명은 내경부재와 외경부재를 판 형태로 공급하면서 그 사이에 프로파일을 공급하여 일체형으로 연결되도록 함으로서 다중벽을 형성하여 강도를 자유롭게 조절할 수 있도록 하는 것으로,The present invention is to supply a profile between the inner diameter member and the outer diameter member in the form of a plate to be connected in one piece by supplying a profile therebetween to form a multi-wall to be able to freely adjust the strength,

더욱 상세하게는 내경부재와 외경부재의 연결부분에 프로파일을 공급하여 연결부분이 상호 일체형으로 융착 연결되도록 하며 프로파일의 사이에 공간이 형성되는 다중 나선형 합성수지관의 제조방법에 관한 것이다.More particularly, the present invention relates to a method of manufacturing a multi-spiral synthetic resin pipe in which a profile is supplied to a connection portion between an inner diameter member and an outer diameter member so that the connecting portions are fused and connected integrally with each other, and a space is formed between the profiles.

종래의 합성수지관은 압출기(10)에서 수지를 용융시켜 공급하면서 사각형 프로파일(32)을 압출하여 냉각기(11)에서 진공상태 또는 수냉 방법으로 냉각시킨 후 관 성형장치(13)의 와인더장치(25)에 나선형으로 공급하면서 프로파일(32)이 서로 닿도록 하고 프로파일(32)의 사이에 보조압출기(20)에서 수지를 공급하여 연결부재(32')를 성형한다.Conventional synthetic resin tube is extruded in the extruder 10 while the resin is extruded square profile (32) and cooled in the cooler 11 in a vacuum or water cooling method after the winder device (25) of the tube forming apparatus (13) ) While the spirals are supplied to the profile 32 so that the profiles 32 touch each other, and the resin is supplied from the sub-extruder 20 between the profiles 32 to form the connecting member 32 ′.

상기 연결부재(32')는 프로파일(32)을 상호 융착 연결시켜 평활한 합성수지관을 성형하게 된다.The connecting member 32 'is fusion-connected to the profile 32 to form a smooth synthetic resin tube.

그러나 종래의 합성수지관은 프로파일(32)과 연결부재(32')가 연결된 경계면이 상호 융착될 때 온도의 편차를 갖고 연결된 것이므로 외관상으로는 일체형으로 연결된 것으로 보이게 되지만, 하중이 가해지는 경우에는 프로파일과 연결부재의 경계면에서 파단 현상이 일어나는 취약한 결점이 있게 되므로 하중이나 윤압에 매우 약하다.However, the conventional synthetic resin pipe is connected with the deviation of temperature when the interface between the profile 32 and the connecting member 32 'are fused together, so it appears to be integrally connected in appearance, but when the load is applied, It is very weak to load or rotational pressure because it has a weak point that breakage occurs at the interface of the connecting member.

이러한 결점을 방지하기 위하여 프로파일의 내부에 열십자 프로파일(41)을 성형하는 삼중 복층관이 제안되었지만, 이 역시 프로파일과 연결부재의 사이에서 충격에 취약한 약점이 나타나게 되므로 원료의 사용량에 비하여 강도가 크게 높아지지 못하였다.In order to prevent such drawbacks, a triple multilayer pipe is proposed in which a crisscross profile 41 is formed inside the profile, but this also results in a weak point that is susceptible to impact between the profile and the connecting member. It did not rise.

또한, 상기와 같은 이중벽관이나 삼중 복층관은 프로파일의 사이에 합성수지를 공급하여 상호 연결되도록 하는 것이므로 내경이나 외표면이 매끄럽지 못한 결점이 있으며, 특히 내경의 매끄럽지 못한 것으로 인하여 물의 흐름이 좋지 못한 결점이 있었다.In addition, the double-walled pipe or the triple-layered pipe as described above are connected to each other by supplying a synthetic resin between the profiles, so that the inner diameter or the outer surface thereof is not smooth, and in particular, the defect of poor water flow due to the smoothness of the inner diameter. there was.

본 발명은 이러한 종래의 결점을 해소하기 위하여 안출된 것으로, 내경에 띠형태의 내경부재를 공급하여 내경에 굴곡이 없이 평활한 관을 성형할 수 있도록 하여 물의 흐름이 좋게 함을 목적으로 한다.The present invention has been made to solve the above-mentioned drawbacks, and the object of the present invention is to provide a strip-shaped inner diameter member to the inner diameter so that a smooth pipe can be formed without bending the inner diameter, thereby improving the flow of water.

본 발명은 내경부재의 경계면 상측으로 공간이 형성되도록 일정한 간격을 두고서 다양한 형태의 프로파일을 공급하여 내경부재가 연결되도록 하여 합성수지관이 빠른 속도로 성형되도록 함을 목적으로 한다.An object of the present invention is to supply a profile of various forms at regular intervals so that a space is formed above the boundary surface of the inner diameter member so that the inner diameter member is connected to be molded at a high speed.

본 발명은 프로파일의 외측으로 띠형태의 외경부재를 공급하여 외경이 굴곡 이 없이 평활한 관을 성형할 수 있도록 함을 목적으로 한다.An object of the present invention is to supply a strip-shaped outer diameter member to the outside of the profile to form a smooth pipe without the outer diameter bend.

본 발명은 내경과 외경에 공급되는 띠형태의 내경부재와 외경부재의 두께 조절에 따라서 강도를 자유롭게 조절할 수 있도록 함을 목적으로 한다.An object of the present invention is to be able to freely adjust the strength according to the thickness of the band-shaped inner diameter member and the outer diameter member supplied to the inner diameter and the outer diameter.

본 발명은 공급되는 수지를 용융시켜 프로파일(32)을 압출기(10)에서 압출하여 냉각기(11)로 공급하면서 진공상태 또는 냉각수를 공급하는 방법으로 성형된 상태가 그대로 유지되도록 냉각한다.The present invention melts the resin to be supplied and extrudes the profile 32 from the extruder 10 to supply the cooler 11, thereby cooling the molded state in a vacuum state or by supplying cooling water.

냉각기(11)를 통과하면서 냉각된 프로파일(12)이 관 성형장치(13)의 와인더장치(25)에 공급될 때 내경에는 판 형태의 내경부재(31)가 공급된다.When the profile 12 cooled while passing through the cooler 11 is supplied to the winder device 25 of the tube forming apparatus 13, the inner diameter member 31 in the form of a plate is supplied to the inner diameter.

상기 관 성형장치(13)는 모터(21)의 동력을 벨트로 감속기(22)에 전달하여 감속시킨 후 기어박스(23)에 공급하여 다수의 죠인트(24)로 와인더축(26)을 각각 연결하여 한번에 다수개의 와인더축(26)이 동시 회전되도록 한다.The tube forming apparatus 13 transfers the power of the motor 21 to the reducer 22 by a belt and then decelerates it, and then supplies the gearbox 23 to connect the winder shaft 26 to the plurality of joints 24. To allow the plurality of winder shafts 26 to rotate simultaneously.

상기 와인더축(26)의 전방에는 전면판(27)이 형성되어 있어서 와인더축(26)을 지지하도록 하며, 이 와인더축(26)은 각도조절 핸들(28)에 연결되어 전체면에서 일정한 경사각도(5∼30°)의 범위로 조절할 수 있도록 한다.The front plate 27 is formed in front of the winder shaft 26 to support the winder shaft 26, the winder shaft 26 is connected to the angle adjusting handle 28, the constant inclination angle in the entire surface Adjust it in the range of (5 ~ 30 °).

상기 와인더축(26)의 경사각도는 프로파일(32)의 간격을 결정하는 것이므로 프로파일(32)의 간격에 의해서 공간(34)의 폭이 결정되는 것이다.Since the inclination angle of the winder shaft 26 determines the spacing of the profile 32, the width of the space 34 is determined by the spacing of the profile 32.

내경부재(31)가 와인더장치(25)의 와인더축(26) 외경에 나선형으로 공급될 때 내경부재(31)의 경계면인 내경 눌림 연결부(35)의 상측으로 프로파일(32)이 공 급 된다.When the inner diameter member 31 is spirally supplied to the outer diameter of the winder shaft 26 of the winder device 25, the profile 32 is supplied to the upper side of the inner diameter pressing connection part 35, which is an interface of the inner diameter member 31. .

상기 프로파일(32)의 사이 상측 중앙에 위치하도록 띠형태의 외경부재(33)를 보조압출기(20)에서 공급한다.The strip-shaped outer diameter member 33 is supplied from the sub-extruder 20 so as to be located at the upper center between the profiles 32.

상기 외경부재(33)의 경계면인 외경 눌림 연결부(36)의 외측에는 누름 로울러(37)가 위치하고 있어서 외경 눌림 연결부(36)를 누르게 되므로 내경에서는 와인더축(26)에 의해서 눌림 역할이 제공된다.Since the pressing roller 37 is located at the outside of the outer diameter pressing connection part 36, which is the boundary surface of the outer diameter member 33, the outer diameter pressing connection part 36 is pressed, so that the inner diameter is provided by the winder shaft 26.

이와 같이 내경 눌림 연결부(35)는 와인더축(26)에 의하여, 외경 눌림 연결부(36)는 누름 로울러(37)에 의하여 눌려지면서 프로파일(32)이 위치하는 폭 만큼 융착이 이루어지면서 상호간에 연결이 된다.In this way, the inner diameter of the pressing portion 35 is pressed by the winder shaft 26, the outer diameter pressing portion 36 is pressed by the pressing roller 37 while the fusion is made as much as the width of the profile 32 is located between the mutual connection do.

여기서 내경부재(31)와 외경부재(33)는 얇은 띠 형태로 공급되는 것이지만 두께를 조절함에 따라서 나선형 합성수지관(30)의 강도를 조절할 수 있는 것으로, 내경부재(31)와 외경부재(33)의 두께를 얇게 성형할수록 강도는 약해지지만, 두껍게(2∼20mm) 성형할수록 강도가 향상됨을 알 수 있다.Here, the inner diameter member 31 and the outer diameter member 33 are supplied in the form of a thin strip, but the strength of the spiral synthetic resin tube 30 can be adjusted according to the thickness adjustment, and the inner diameter member 31 and the outer diameter member 33. The thinner the thickness, the weaker the strength, but the thicker the thickness (2-20mm) it can be seen that the strength is improved.

이와 같이 연속해서 성형되면서 프로파일(32)의 사이에 공간(34)이 형성되는 것이며, 도 10 에 도시한 바와 같이 나선형 합성수지관(30)이 성형 된다.As described above, the space 34 is formed between the profiles 32 while being continuously molded. As shown in FIG. 10, the spiral synthetic resin tube 30 is molded.

성형되는 나선형 합성수지관(30)은 절단장치(14)에서 일정한 길이(약 6m)로 절단된 후 배출장치(15)를 통하여 배출되는 것이다.The molded spiral synthetic resin pipe 30 is cut to a predetermined length (about 6m) in the cutting device 14 and then discharged through the discharge device (15).

상기 프로파일(32)은 사각형으로 성형하였으나, 도 12 에 도시한 바와 같이 원형으로 형성되는 원형 프로파일(40)을 공급하여 성형할 수 있으며, 도 13 에 도시한 바와 같이 내부에 열십자 형태의 보강대가 일체형으로 성형된 열십자 프로파 일(41)을 공급하여 성형할 수 있는 것이다.The profile 32 is formed in a rectangular shape, but can be formed by supplying a circular profile 40 formed in a circular shape as shown in FIG. 12, and as shown in FIG. It can be molded by supplying a crisscross profile 41 molded integrally.

또한, 도 14 에 도시한 바와 같이 내부에 엑스자 형태의 보강대가 일체형으로 성형된 엑스자 프로파일(42)을 공급하여 성형할 수 있으며, 도 15 에 도시한 바와 같이 프로파일의 내부가 채워진 채움 프로파일(43)을 공급하여 성형할 수 있는 것이다.In addition, as shown in FIG. 14, the X-shaped reinforcing rod may be formed by supplying the X-shaped profile 42 integrally formed therein, and as shown in FIG. 43) can be supplied by molding.
