Description
본 발명은 배수관으로 사용되는 합성수지관에 관한 것으로, PE와 재생원료를이루어진 압출수지관을 압착하여 겹치게 권회 시킴으로써 단면이 삼중으로 이루어지는 삼중관과 그 제조방법에 관한 것이다.The present invention relates to a synthetic resin pipe to be used as a drain pipe, and relates to a triple pipe made of a triple cross section by winding and overlapping the extruded resin pipe made of PE and recycled raw material overlapping.
배수관으로 사용되는 기존 파이프는 PVC관, 나선형 주름관이 주로 사용되고 있으나 PVC관은 압출하여 생산하는 관계로 직경이 크거나 두께가 두꺼울 경우 생산이 어렵고 제조비용이 크게 증가되는 문제점이 있으며, 나선형 주름관은 내압과 충격에 약하고 운송도중 중량에 의해 중간부위가 부러지는 문제점이 있다.PVC pipes and spiral corrugated pipes are mainly used as drainage pipes. However, PVC pipes are extruded and produced, so if the diameter is large or thick, production is difficult and manufacturing costs are greatly increased. It is weak to excessive shock and there is a problem that the middle part is broken by weight during transportation.
이러한 문제점을 해결하기 위하여 외피와 내피가 PE 재질로 이루어지고 외피와 내피 사이의 중간층이 비교적 두꺼운 재활용합성수지로 이루어진 삼중관을 제조하므로써 내압, 충격, 강도가 강한 배수관을 제공하는 한편 농촌에서 폐기되는 비닐을 이용한 재활용재를 사용하여 가격을 낮추도록 하고 있으나, 기존의 삼중관은 외피와 내피를 이루는 PE를 압출시키는 노즐과 재활용재를 압출시키는 노즐을 구비하여야 하므로 구조가 복잡하다.In order to solve this problem, vinyl is discarded in rural areas while providing a drain pipe with strong pressure, impact and strength by manufacturing a triple pipe made of recycled synthetic resin with a thick outer skin and inner skin made of PE material. The use of recycled materials to reduce the price, but the conventional triple pipe has a complex structure because the nozzle and the nozzle for extruding the recycled material to extrude the PE forming the outer skin and the inner skin.
그리고 기존의 삼중관은 도 6 과 같이 띠모양의 띠수지(7)를 와인더(1)의 롤러에 권회 시키되 2/3씩 맞물리게 하여 권회 시킴으로써 제작하고 있으나, 삼중관(6)의 내측을 이루는 부분의 띠수지(7)가 맞닿는 부분에서 평편하게 성형되지 못하고 틈(8)이 벌어지게 되어 하수가 흐를 때 저항을 주는 한편 누수가 발생될 소지가 있었다.And the existing triple pipe is produced by winding the belt-shaped band resin (7) to the roller of the winder (1) as shown in Figure 6 by engaging two-thirds of the winding, but forming the inside of the triple pipe (6) In the part where the band resin 7 is in contact with each other, the gap 8 is opened and the gap 8 is opened, thereby resisting the sewage and leaking.
본 발명은 단면이 삼중으로 이루어진 삼중관에 있어서, 내측과 외측이 PE 로 이루어 지고 그 사이가 재활용재로 이루어진 압출수지관을 압착시킨 후 이를 이용하여 2/3씩 맞물리게 권회 시킴으로써 삼중관을 제조하는 것으로, 하나의 노즐만 사용하여 최외측과 최내측이 PE 로 씌워지고 PE 사이에는 재활용재가 들어가는 삼중관을 만드는 것이다.According to the present invention, in the triple pipe consisting of a triple cross section, the inside and the outside are made of PE, and the extrusion resin tube made of recycled material is compressed therebetween, and then wound by 2/3 by using the same to manufacture a triple pipe. By using only one nozzle, the outermost and innermost surfaces are covered with PE, and a triple tube is formed between the PEs and recycled material.
본 발명의 삼중관은 재활용재의 내,외측을 PE 로 씌운 파이프 형상의 압출수지관을 압착하여 띠수지로 와인더 외측에 감아주되 띠수지의 2/3씩을 맞물리게 하고, 외측에서는 띠수지의 내측틈을 없애는 압착롤러로 압착시켜 가며 감아 줌으로써 제조되어진다.The triple pipe of the present invention is to compress the pipe-shaped extruded resin tube covered with PE inside and outside of the recycled material, and wound around the outside of the winder with a band resin to engage two-thirds of the band resin, and from the outside to the inner gap of the band resin It is manufactured by winding by pressing with a pressing roller that removes.
이러한 본 발명은 띠수지가 한겹 감기는 부분과 두겹 감기는 부분을 압착하는 압착롤러에는 돌출부를 주어 띠수지 사이의 틈을 없애도록 한다.The present invention is to give a compression to the compression roller for compressing the portion of the single-wound and double-wound winding of the strip resin to eliminate the gap between the strip resin.

본 발명의 삼중관 제조장치는 도 1 에 도시된바와 같이 압출수지관(21)을 압출시키는 하나의 노즐(2)을 설치하고, 노즐(2)의 하부에는 회전되는 와인더(1)를 설치하며, 와인더(1)의 측면에는 압착롤러(10)를 설치한다.In the triple pipe manufacturing apparatus of the present invention, as shown in FIG. 1, one nozzle 2 for extruding the extruded resin tube 21 is installed, and a lower winder 1 is installed below the nozzle 2. And, the side of the winder (1) is installed a pressing roller (10).
여기서 와인더(1)를 회전시는 구동장치 및 와인더(1)쪽으로 물을 분사시키는 노즐은 도시와 설명을 생략한다.Here, the nozzle for injecting water toward the driving device and the winder 1 when the winder 1 rotates, illustration and description will be omitted.
본 발명의 노즐(2)에서 압출되는 압출수지관(21)은 도 4 에 도시된바와 같이 파이프 형상을 갖고 압출되며 이때 압출수지관(21)의 내측과 외측에는 PE(4)(5) 가 씌워지고 그 사이에 재활용재(3)가 위치 된다.The extruded resin tube 21 extruded from the nozzle 2 of the present invention has a pipe shape as shown in FIG. 4, and is extruded. In this case, PE 4 and 5 are provided on the inside and the outside of the extruded resin tube 21. The recycled material 3 is positioned between the two.
이같이 하나의 노즐(2)에서 재활용재(3)의 내,외측에 PE (4)(5)를 씌워준채로 압출하는 장치는 공지된 기술이다.As such, a device for extruding the PE (4) (5) on the inside and the outside of the recycled material (3) in one nozzle (2) is a known technique.
노즐(2)에서 압출된 압출수지관(21)은 냉각되지 않은채로 와인더(1)에 감기게 되므로 와인더(1)에는 도 5 와 같이 압착된 띠 모양의 띠수지(22)형태로 감겨지게 된다.The extruded resin tube 21 extruded from the nozzle 2 is wound on the winder 1 without being cooled, so that the winder 1 is wound in the form of a band-shaped band resin 22 compressed as shown in FIG. 5. You lose.
띠수지(22)는 내,외측이 PE(4)(5)로 쌓여져 있어 띠모양으로 압착될 경우 내측의 PE(4)는 서로 붙게 되고, 외측이 PE(5)로 둘러 쌓인 상태가 되며, 이러한 띠수지(22)를 와인더(1)에 감아주되 먼저감긴 띠수지(22)의 2/3가 겹쳐 지도록 다음번 띠수지(22)를 감아준다.The band resin 22 is piled up inside and outside PE (4) (5), and when pressed in a band shape, the inside PE (4) is stuck together, the outside is surrounded by PE (5), Winding the band resin 22 to the winder 1, but then wound the next band resin 22 so that two-thirds of the first wound belt resin 22 overlaps.
그러면 띠수지(22)는 3겹으로 와인더(1)에 감겨져 삼중관(20)을 구성하게 되며, 삼중관(20)의 내,외측에는 PE(4)(5)가 위치하게 되므로 기존과 같이 재활용재의 내,외측에 PE 를 씌워주지 않아도 된다.Then, the band resin 22 is wound on the winder 1 in three layers to form a triple tube 20, and since the PE (4) (5) is positioned inside and outside of the triple tube 20, Likewise, it is not necessary to cover PE inside and outside the recycled material.
즉 PE 를 감고 재활용재를 감은후 다시 PE 를 감아주어 삼중관의 내,외측에 PE 가 위치되게 하는 불편이 사라지고, 단지 띠수지(22)를 와인더(1)에 감아주는 동작만으로 재활용재(3)의 내,외측에 PE(4)(5)가 위치하게 되는 삼중관(20)의 제조가 가능하게 된다.In other words, after winding the PE and recyclable material, the PE is wound again to eliminate the inconvenience of placing the PE inside and outside of the triple pipe, and only the operation of winding the band resin 22 on the winder 1 is used as a recyclable material ( It is possible to manufacture the triple tube 20 in which the PE (4) (5) is located inside and outside of 3).
이같이 와인더(1)에 띠수지(22)를 감아줄 때 와인더(1)의 외측에는 압착롤러(10)를 설치하여 와인더(1)에 감겨지는 띠수지(22)를 외측에서 내측으로 밀어주므로써 삼중관(20)의 모양을 잡아주게 된다.In this way, when the band resin 22 is wound around the winder 1, a compression roller 10 is installed on the outside of the winder 1 to wind the band resin 22 wound around the winder 1 from the outside to the inside. By pushing to hold the shape of the triple tube (20).
이때 압착롤러(10)는 직경이 다르게 3 단으로 구성하되 제일 큰 직경부분은 한겹으로 감긴 띠수지(22)를 압착하고, 중간 직경부분은 두겹으로 감긴 띠수지(22)를 압착 하도록 하며, 제일 적은 직경부분은 3 겹으로 감긴 띠수지(22)를 압착하도록 한다.At this time, the pressing roller 10 is composed of three stages with different diameters, but the largest diameter portion is to press the belt resin 22 wound in one layer, and the middle diameter portion to press the belt resin 22 wound in two layers, the first The smaller diameter portion is to compress the three-ply wound belt resin (22).
압착롤러(10)에서 한겹으로 감긴 띠수지(22)를 누르는 부분과 두겹으로 감긴 띠수지(22)를 누르는 부분이 서로 만나는 곳에는 돌출부(11)를 주어 삼중관(20)의 내측에서 두겹이 겹쳐지는 부분을 강하게 압착시켜 삼중관(20)의 내측에서 틈이 발생되지 않도록 한다.Where the pressing part of the banded resin 22 wound in the pressing roller 10 and the pressed part of the banded resin 22 wound in two layers meet each other, a protrusion 11 is provided to double the inner side of the triple tube 20. The overlapping part is strongly compressed so that a gap does not occur inside the triple tube 20.
그리고 압착롤러(10)의 직경이 두꺼운 쪽 최외측에는 압착돌기(12)를 형성시켜 돌출부(11)가 띠수지(22)를 누를 때 띠수지(22)가 압착돌기(12)쪽으로 밀리지 않고 띠수지(22)가 겹쳐지는 쪽으로 밀리게 한다.In addition, the outermost side of the pressing roller 10 having a larger diameter forms a pressing protrusion 12 so that the band resin 22 does not push toward the pressing protrusion 12 when the protrusion 11 presses the band resin 22. The resin 22 is pushed in the overlapping direction.
즉 압착롤러(10)는 와인더(1)쪽에서 볼 때 띠수지(22)끼리 만나는 부분을 외측에서 강하게 눌러주어 띠수지(22)가 겹쳐지는 부분에서의 틈이 발생하지 않도록 하므로써 기존 삼중관에서 나타나는 문제점을 해결하게 된다.In other words, the pressing roller 10 presses the portions where the band resins 22 meet strongly from the outside when viewed from the winder 1 side, so that a gap does not occur in the area where the band resins 22 overlap, and thus, in the existing triple pipe. This solves the problem.
본 발명은 하나의 노즐을 이용하여 삼중관을 제조하게 되므로 구조가 간단하고, 압출수지관을 압착시킨 띠수지를 사용하여 삼중관을 제조하게 되어 재활용재의 내,외측을 감싸는 PE를 별도로 씌워주지 않아도 된다.In the present invention, since the triple pipe is manufactured using a single nozzle, the structure is simple, and the triple pipe is manufactured by using a strip of resin compressed into the extruded resin tube, so that PEs surrounding the inside and the outside of the recycled material are not separately covered. do.
그리고 삼중관의 내측에서 띠수지가 겹쳐지는 부분을 외측에서 압착롤러로 강하게 압착시켜 주어 삼중관 내부에서 틈이 발생하지 않고 매끄러운 형태로 제작이 가능하다.In addition, the band resin overlaps the inside of the triple tube with strong pressing rollers from the outside, so it is possible to produce a smooth form without a gap inside the triple tube.
또한 압출수지관을 압착시켜 삼중관을 제조하게 되므로 삼중관 제조시 냉각이 충분히 이루어 지게 되어 냉각에 따른 문제를 어느정도 해결하게 된다.In addition, the extrusion resin tube is pressed to produce a triple tube, so that the cooling is sufficiently made when the triple tube is manufactured to solve the problem of cooling to some extent.
