본 발명은 관개용수의 송배수용 호스의 제조방법에 관한 것이다.The present invention relates to a method for producing a hose for the delivery and drainage of irrigation water.

종래 관개용수 송배수관으로 플라스틱파이프나 나선상 P.V.C호수가 주로사용되었으나, 플라스틱 파이프는 운반과 설치작업이 곤란하고, 나선상 P.V.C호스는 중량이 무겁고 유연성이 적어 파손되기 쉬운 결점이 있으며, 근래에는 직포호스내에 원통상 P.V.C 필름호스를 삽입하고 이것을 P.V.C 페이스트 수지액에 통과시켜 제조한 호스도 사용되고 있으나, 이것은 가볍고, 말아서 보관 및 운반할 수 있는 장점은 있으나 표면이 거칠고, 직포와 P.V.C 필름호스의 접착이 불완전할 뿐만 아니라, 직포 호스내에 원통상 P.V.C를 삽입해야 하므로 일정길이 이상의 호스는 제조할 수 없어 사용시 직포와 P.V.C 필름호스가 분리된다거나 표면이 거칠어 파손되기 쉽고 일정길이 이상인 경우에는 연결사용해야 하는 등의 결점이 있었다.Conventionally, plastic pipes or spiral PVC lakes are mainly used for irrigation water delivery and drainage pipes, but plastic pipes are difficult to transport and install, and spiral PVC hoses have a heavy weight and low flexibility and are easily damaged. Usually, a hose manufactured by inserting a PVC film hose and passing it through a PVC paste resin liquid is also used, but it is light and has the advantage of being stored and transported, but the surface is rough and the adhesion between the woven fabric and the PVC film hose is incomplete. However, since the cylindrical PVC must be inserted into the woven hose, a hose longer than a certain length cannot be manufactured.Therefore, there is a drawback that the woven fabric and the PVC film hose are separated during use, or the surface is rough and easily broken, and if it is longer than a certain length, it must be connected. .

따라서 본 발명의 목적은, 상술한 바와 같은 단점을 제거할 수 있는 관개용수의 송배수용호스를 제조하기위한 방법을 제공하는 데 있으며, 본 발명에 의해 제조된 호스는 원통형, 직포내의 양면에 P.V.C페이스트수지액을 두껍게 피복하여 된 것으로 유연성과 경량성이 양호하여 호스를 말아서 보관 또는 운반하기 좋고 특히 내외면이 평활하게 되어 있어 내부 수압 손실을 극소화할 수 있는 특징은 물론 외부 마찰로 인한 호스의 파손을 방지할 수 있고, 더우기 호스의 길이를 약 100m라도 연속적으로 길게 제조할 수 있어 이용효율을 극대화시킬 수 있는 특징을 갖고 있다.It is therefore an object of the present invention to provide a method for producing a hose for the delivery and drainage of irrigation water that can eliminate the disadvantages described above, the hose produced by the present invention is a cylindrical, PVC paste on both sides in the woven fabric It is a thick coating of resin liquid, which is good in flexibility and light weight, so it can be rolled up for storage or transportation. In particular, the inner and outer surfaces are smooth to minimize internal hydraulic pressure loss. It can be prevented, and furthermore, because the length of the hose can be continuously manufactured even about 100m long, it has the characteristic of maximizing utilization efficiency.

이하 첨부도면을 참고로 본 고안의 관개용 수의 송배수용호스의 제조방법을 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the manufacturing method of the water hose for irrigation water of the present invention.

제 1 도는 송배수용 호스의 제조방법을 나타내는 장치의 개요도로서 여기서 표시번호 1은 원통형 직포가 감겨있는 권취드럼으로서 여기에는 원하는 직경과 길이를 갖는 원통형 직포가 납작하게 접혀진 상태로 감겨있어 이는 두 개의 안내롤러(2)를 통하여 접혀진 직포를 다시 원통형으로 복원시켜 주는 형유지기(3)에 공급된다. 여기서 형유지기(3)은 제2도의 정면도와 제3도의 평면도에서 상세히 볼 수 있는 바와같이 2쌍의 소형롤러(4)와 소형롤러(4)하단에 설치되는 반원형 안내홈(5a)을 갖는 두개의 닙롤러(5)가 현수간(6), 지지틀(8) 및 현수간(6)의 상단을 잡아 주는 너트(7)등에 의해 만드릴(9)상에 지지되어 있다. 여기서, 소형롤러(4)는 접혀서 공급되는 직포속에 내장되어 접힌 직포를 펼쳐주는 역활을 하며, 두 개의 닙롤러(5)는 외부에서 펼쳐진 직포를 반원형안내홈(5a)에 의해 현수간(6)상으로 관통시킴으로써 직포의 주름을 완전히 펴주는 역활을 한다.1 is a schematic view of a device showing a manufacturing method of the hose for transmission and drainage, wherein the reference numeral 1 is a winding drum in which a cylindrical woven fabric is wound, in which a cylindrical woven fabric having a desired diameter and length is wound in a flat folded state. The rollers 2 are supplied to the mold holder 3 for restoring the woven fabric back into a cylindrical shape. Here, the mold holder 3 has two pairs of small rollers 4 and semi-circular guide grooves 5a installed at the lower ends of the small rollers 4 as can be seen in detail in the front view of FIG. 2 and the plan view of FIG. Two nip rollers 5 are supported on the mandrel 9 by a suspension rod 6, a support frame 8, and a nut 7 for holding the upper end of the suspension rod 6. Here, the small roller (4) is embedded in the woven fabric to be folded and serves to unfold the folded woven fabric, the two nip rollers (5) are suspended from the outer woven fabric by the semicircular guide groove (5a) (6) It penetrates the upper part of the woven fabric to completely smooth out the wrinkles.

이와같이 주름이 펴진 원통형 직포는 다시 만드릴(9)에 의해 원통형 상태를 유지하면서 통과되어 P.V.C페이스트 수지액통(11)으로 투입된다. 이때 만드릴(9)는 직포의 내부에 내재하여 있고, 직포외부에는 1차지지봉(10)이 직포를 지지시키면서 수지액통(17)내로 안내해 준다. 만드릴(9)하부에는 수지액통(11)이 있고, 수지액통(11)하부에는 심봉(12)가 수지액통(11)을 지지시켜 주도록 만드릴(9)와 연결되어 있다. 한편, 심봉(12)는 원통형 직포가 수지액통(11)을 통과할 때, P.V.C 페이스트 수지액이 직포에 침투되면서 적당한 두께의 수지층을 만들도록 원통형 형상의 두 개의 관통공(13)을 갖고 있다. 이 관통공(13)은 직포내외면 상에 P.V.C 페이스트 수지층을 균일하게 피복시켜 주는 역활을 하는 한편, 수지층 표면을 평활하게 해주는 역활을 한다. 본 실시예에서는 관통공(13)의간극이 1mm 정도로 유지되어 원통형 직포는 P.V.C 페이스트 수지액이 도면에서 점선으로 보인 바와같이 1mm 의 두께를 내외로 침투되어 있는 상태이다. 한편, 심봉(12)의 하부에는 보다 작은 직경의 연결봉(14)이 연결되어 있고, 그의 최하단에는 직포의 직경과 거의 동일한 원추형드럼(18)이 구성되어 있으며, 심봉(12)과 원추형드럼(18)사이의 연결봉(14)외 부주변에는 침투되어 피복된 수지층을 고착시키도록 열처리하기 위한 히이터(15)가 구성되어 있고, 히이터(15)다음, 즉 원추형드럼(18)의 바로 위에는 냉각노즐(16)이 형성되어 있어 관통공(13)을 통하여 배출되는 원통형 직포는 히이터(15)에 의해 200-230℃로 2-3분간 열처리된 후 냉각노즐(16)에서 분사되는 냉각수에 의해 급냉되어 2차지지봉(17)과 원추형드럼(18)을 통과하면서 냉각통(19)에 투입된다. 이 냉각통(19)에서 원통형 직포에 피복된 수지액은 완전히 고착되어 완제품 호스가 된다. 이 완제품 호스는 원추형드럼(18)에 의해 안내롤러(20)상에 다시 접힌 상태로 안내되어 안내롤러(21)을 통하여 권취드럼(22)에 감기게 된다.The cylindrical woven fabric thus expanded is passed again while maintaining the cylindrical state by the mandrel 9 and introduced into the P.V.C paste resin liquid container 11. At this time, the mandrel 9 is inherent in the inside of the woven fabric, and the outer side of the woven fabric guides the primary support rod 10 into the resin liquid container 17 while supporting the woven fabric. The lower part of the mandrel 9 has a resin liquid container 11, and the lower part of the mandrel 9 is connected to the mandrel 9 so that the core rod 12 supports the resin liquid container 11. On the other hand, the core rod 12 has two cylindrical through-holes 13 so that when the cylindrical woven fabric passes through the resin liquid container 11, the PVC paste resin liquid penetrates into the woven fabric to form a resin layer of a suitable thickness. . The through hole 13 serves to uniformly coat the P.V.C paste resin layer on the inner and outer surfaces of the woven fabric, and serves to smooth the surface of the resin layer. In the present embodiment, the gap between the through holes 13 is maintained at about 1 mm, and the cylindrical woven fabric is in a state in which the P.V.C paste resin liquid penetrates inside and outside the thickness of 1 mm as shown by the dotted lines in the figure. On the other hand, a lower diameter connecting rod 14 is connected to the lower part of the mandrel 12, and at the lower end thereof, a conical drum 18 almost equal to the diameter of the woven fabric is formed, and the mandrel 12 and the conical drum 18 are formed. Heater 15 for heat treatment to fix the penetrated and coated resin layer is formed in the outer periphery of the connecting rod 14 between the gaps 14) and the cooling nozzle immediately after the heater 15, i.e., just above the conical drum 18. (16) is formed and the cylindrical woven fabric discharged through the through hole 13 is heat-treated at 200-230 ° C for 2-3 minutes by the heater 15 and then quenched by the cooling water sprayed from the cooling nozzle (16) While passing through the secondary support rod 17 and the conical drum 18, it is introduced into the cooling tube 19. In this cooling cylinder 19, the resin liquid coated on the cylindrical woven fabric is completely fixed and becomes a finished hose. The finished hose is guided back on the guide roller 20 by the conical drum 18 and wound around the winding drum 22 through the guide roller 21.

본 발명에서 사용되는 원통형 직포는 실의 인장강도가 높고 200℃정도에서도 견딜 수 있고, P.V.C페이스트와 접착성이 좋은 합성섬유제로서 폴리에스텔제가 바람직하다. P.V.C 페이스트 수지액은 공지된 바와 같이 P.V.C 페이스트수지에 적량의 가소제(D.O.P.,D.H.P., D.B.P., D.O.A)와 안정제(Pb-St, Ca-St, Zn-St)등을 상온에서 혼합하여 액체상태로 한 것이면 좋으며, 안료는 원하는 색상에 따라 임의로 택할수 있다.The cylindrical woven fabric used in the present invention has a high tensile strength of the yarn and can withstand about 200 ° C., and a polyester is preferable as a synthetic fiber having good adhesion to P.V.C paste. As is known, the PVC paste resin liquid is prepared by mixing an appropriate amount of plasticizers (DOP, DHP, DBP, DOA) and stabilizers (Pb-St, Ca-St, Zn-St) with PVC paste resin at room temperature. The pigment may be arbitrarily selected according to the desired color.

상술한 바와같은 본 발명의 방법에 의해 제조된 호스는 제4도에서와 같이 원통형 직포에 수지층이 침투되어 내외 표면에 평활한 면이 두텁게 형성되는데 이 수지층의 두께는 심봉(12)의 관통공(13)의 간극의 크기에 따라 조절될 수 있으며, 직경이 다른 호스의 제조는 심봉(12)을 교체함으로써 가능하다. 특히 중요한것은 호스의 내외 표면을 평활한 면이 되도록 제조함으로써 내부수압 손실을 극소화할 수 있는 한편 외부마찰로 인한 파손 방지등의 효과가 있고 더우기 호스의 길이를 1000m 정도로 길게 생산할 수 있으므로 관개용수의 송배수용 호스로서 대단히 사용이 편리하다.In the hose manufactured by the method of the present invention as described above, as shown in FIG. 4, the resin layer penetrates into the cylindrical woven fabric, and a smooth surface is formed on the inner and outer surfaces, and the thickness of the resin layer is the penetration of the core rod 12. It can be adjusted according to the size of the gap of the ball 13, the production of hoses of different diameters is possible by replacing the mandrel 12. Particularly important is that the internal and external surfaces of the hose are made to be smooth to minimize the internal hydraulic pressure loss while preventing damage caused by external friction, and moreover, the length of the hose can be produced as long as 1000m, so that the water can be delivered to the irrigation water. It is very convenient to use as a receiving hose.
