본 발명은 다중관체 제조장치 및 그 제조방법에 관한 것으로서, 좀 더 상세히는 자동화라인을 통해 연속적인 제조가 가능하고, 방수성이 우수하고 결로를 방지할 수 있는 새로운 구조의 다중관체 제조장치 및 그 제조방법에 관한 것이다.The present invention relates to a multi-pipe manufacturing apparatus and a method for manufacturing the same, and more specifically, to a multi-pipe manufacturing apparatus and a manufacturing of a new structure that can be continuously manufactured through an automated line, excellent waterproofness and can prevent condensation. It is about a method.

종래에 에어컨의 실내기와 실외기를 연결하는 배관에는 고압냉매관 및 저압냉매관과 함께 전원선과 제어선 등의 전기선이 통과되는 전선관이 단열재 등에 의해 둘러싸여 한 묶음으로 제작된다. 이 때, 단열재 등에 수분이 침투하면 단열성이 저하되므로 이를 방지하기 위해 이들 배관 또는 이를 둘러싸는 단열재의 외부에 방수필름을 테이핑하여 외피를 피복하게 된다. 그런데, 종래의 이러한 에어컨용 다중관체를 방수필름으로 테이핑 작업하는데 시간이 많이 소요되므로 생산성이 낮고, 테이핑된 필름의 이음매 사이의 틈새로 수분이 침투되는 것이 완전히 방지되지 못하여 결로가 발생하고 이로 인해 단열성이 저하되는 문제점이 있다. 아울러, 이러한 테이핑에 의해 얻어지는 외피는 배관에 대한 밀착성이나 견고성이 상대적으로 취약하여 부분적인 손상에 의해 쉽게 풀릴 수 있어서 제품의 내구성이 저하되는 문제점이 있다.Conventionally, in a pipe connecting an indoor unit and an outdoor unit of an air conditioner, a conduit through which electric wires such as a power line and a control line pass together with a high pressure refrigerant tube and a low pressure refrigerant tube is produced in a bundle surrounded by an insulation material. At this time, when moisture penetrates into the heat insulating material, the heat insulating property is reduced, so that the waterproof film is taped to the outside of these pipes or the heat insulating material surrounding the pipe in order to prevent the coating. However, since the conventional multi-tubular body for air conditioner takes a long time to tap the waterproof film, the productivity is low, and condensation occurs because moisture is not prevented from completely penetrating into the gap between the joints of the taped film. There is a problem of this deterioration. In addition, the outer skin obtained by taping is relatively weak to the adhesion or firmness to the pipe can be easily released by partial damage, there is a problem that the durability of the product is reduced.

한편, 종래에 이들 다중 배관이나 이를 둘러싸는 단열재를 방수필름으로 둘러싸는 방법도 사용되고 있으나, 일정한 크기로 절단된 방수필름으로 배관을 둘러 싸야 하므로, 연속공정을 통한 생산이 곤란하여 자동화된 일관생산이 곤란하고 필름의 이음매 부분이 단열이나 방수의 취약부가 되어 제품의 품질이 저하되는 문제점이 있었다.Meanwhile, a method of enclosing these multiple pipes or insulating materials surrounding them with a waterproof film is also used in the related art, but since the pipes must be enclosed with a waterproof film cut to a certain size, production through a continuous process is difficult and automated consistent production is achieved. It is difficult and the joint portion of the film is a weak part of the insulation or waterproof, there was a problem that the quality of the product is reduced.

이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 다. 도 1은 본 발명에 의해 제작되는 다중관체의 예로서, 단열재로 둘러싸인 금속관으로 이루어진 두 개의 냉매공급관(12,14)과 합성수지 주름관 형태의 전선관(16)으로 이루어진 에어컨 배관을 예시적으로 보여준다. 도 2는 본 발명에 따른 장치의 일 실시예의 개략구성도이고, 도 3과 도 4는 본 발명의 요부 사시도 및 단면구성도이다. 도시된 실시예는 도시된 바와 같이, 각각의 관체(12,14,16)가 릴 형상의 관체공급부(22,24,26)를 통해 연속적으로 공급된다. 이들 관체(12,14,16)는 채널형상의 안내부재(28)를 통해 안내되면서 길이방향으로 서로 근접되도록 된다. 이 안내부재(28)의 일측에는 압출기(30)가 배치된다. 이 압출기(30)는 수지재료가 공급되는 호퍼(37)와 재료가 용융되면서 압송되도록 히터와 스크류가 구비된 압출기본체(38)를 포함한다. 이 압출기본체(38)의 선단부에는 측방으로 연장되는 연결관(39)을 통해 압출헤드(31)가 구비된다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. FIG. 1 shows an example of an air conditioner pipe consisting of two refrigerant supply pipes 12 and 14 made of a metal pipe surrounded by a heat insulating material, and a conduit pipe 16 in the form of a synthetic resin corrugated pipe. 2 is a schematic configuration diagram of an embodiment of the apparatus according to the present invention, and FIGS. 3 and 4 are a perspective view and a cross-sectional configuration view of main parts of the present invention. In the illustrated embodiment, as shown, each tube 12, 14, 16 is continuously supplied through the reel-shaped tube supply unit 22, 24, 26. These tubular bodies 12, 14, 16 are guided through the channel-shaped guide member 28 to be close to each other in the longitudinal direction. One side of the guide member 28, the extruder 30 is disposed. The extruder 30 includes a hopper 37 to which the resin material is supplied and an extrusion main body 38 provided with a heater and a screw so as to be conveyed while the material is melted. The tip end of the extrusion main body 38 is provided with an extrusion head 31 through a connecting pipe 39 extending laterally.

이 압출헤드(31)는 그 내부에 단면 원형의 통로(32)가 형성되며, 이 통로(32)에는 전술한 안내부재(28)가 연결되어 관체(12,14,16)가 통과된다. 그리고, 이 압출헤드(31)의 통로(32)의 둘레부에는 상기 압출기(30)에서 압출된 용융수지가 토출되는 링형상의 압출슬릿(34)이 구비된다. 이에 따라, 압출헤드(31)의 통로(32)를 통해 나오는 다수의 관체(12,14,16)가 압출슬릿(34)을 통해 단면 원형의 슬리이브형태로 압출되어 나오는 수지필름(20)에 둘러싸이게 된다.The extrusion head 31 has a passage 32 having a circular cross section therein, and the guide member 28 described above is connected to the passage 32 through which the tubular bodies 12, 14, and 16 pass. A ring-shaped extrusion slit 34 through which the molten resin extruded from the extruder 30 is discharged is provided at the periphery of the passage 32 of the extrusion head 31. Accordingly, a plurality of tubular bodies 12, 14, 16 exiting through the passage 32 of the extrusion head 31 is extruded through the extrusion slit 34 in the shape of a sleeve having a circular cross section to the resin film 20. Is surrounded.

이와 같이 다수의 관체(12,14,16)가 수지필름(20)에 둘러싸인 상태에서, 도 5 및 도 6에 도시된 바와 같이, 그 다음 단에 설치된 다수의 노즐(42,44)로 이루어진 노즐기구(40)에 의해 압축공기가 분사된다. 그러면, 수지필름(20)이 관체(12,14,16) 쪽으로 가압되어 밀착되면서 냉각된다. 이어서 그 후단에 배치되며 냉각수가 공급되는 냉각부(50)를 통과하면서 수지필름(20)이 급속히 경화되면서 다중관체(10)가 형성된다. 이어서 이송컨베이어(60)를 통해 다중관체(10)를 인출하면 서 이를 권취하여 제품을 완성한다. 이러한 과정을 통해 도 1에 도시된 바와 같이 다수의 관체(12,14,16)가 수지필름(20)에 의해 밀착되면서 외피인 수지필름(20)에 이음매가 없는 다중관체가 완성된다.Thus, a plurality of nozzles (12, 14, 16) is surrounded by a resin film 20, as shown in Figure 5 and 6, a nozzle consisting of a plurality of nozzles 42, 44 installed in the next stage Compressed air is injected by the mechanism 40. Then, the resin film 20 is pressed while being in close contact with the tubular body 12, 14, 16 and cooled. Subsequently, the multi-layer body 10 is formed while the resin film 20 is rapidly cured while passing through the cooling unit 50 through which the coolant is supplied. Subsequently, the multi-conduit 10 is drawn out through the transfer conveyor 60 to be wound up to complete the product. Through this process, as shown in FIG. 1, a plurality of tubes 12, 14, and 16 are closely attached to each other by the resin film 20, thereby completing a seamless multi-tube body on the outer resin film 20.

이상에서 설명한 본 발명에 따르면, 에어컨 배관이나 기타 다수의 배관이 집속되어 외피로 둘러싸이는 다중관체(10)를 제조함에 있어서, 이들 관체(12,14,16)를 길이방향으로 근접시켜서 압출기(30)의 압출헤드(31)의 통로(32)를 통과시키면서 그 둘레부의 압출슬릿(34)을 통해 수지필름(20)을 압출시킴으로써 이음매 없는 다중관체의 외피를 형성할 수 있고, 이어서 압축공기 또는 가압수를 분사시켜서 수지필름(20)을 관체(12,14,16)에 밀착시킬 수 있으므로, 연속공정이 가능하여 생산성이 향상되면서도 외피의 이음매나 틈새가 없어서 수분침투로 인한 단열성능 저하나 결로의 우려가 없는 고품질의 방수성 다중관체를 얻을 수 있다.According to the present invention described above, in the manufacture of a multi-tubular body 10 in which an air conditioner pipe or a plurality of other pipes are concentrated and surrounded by an outer sheath, the pipe bodies 12, 14, and 16 are proximate longitudinally and extruder 30 Extruded resin film 20 through the extrusion slit 34 at its periphery while passing through the passage 32 of the extruded head 31), thereby forming a seamless multi-shell outer shell, and then pressurized air or pressurization. Since the resin film 20 can be brought into close contact with the tubular bodies 12, 14 and 16 by spraying water, the continuous process is possible, and there is no seam or gap of the outer shell while the productivity is improved. A high quality waterproof multi-tubular body can be obtained without any concern.

또한, 압축공기를 분사하는 노즐기구(40)의 노즐(42)을 다수의 관체(12,14,16)가 모여서 이루어지는 골부분(18)에 집중적으로 분사시킴으로써, 가압수를 사용하는 경우에 필요한 물의 공급 및 순환장치가 불필요하면서도 외피인 수지필름(20)이 집속된 관체의 외관형태에 일체가 되도록 밀착되어 경화되므로, 외피인 수지필름(20)의 손상 등이 방지되어 내구성이 더욱 증대된다. In addition, by intensively spraying the nozzle 42 of the nozzle mechanism 40 for injecting the compressed air to the bone portion 18 formed by the plurality of tubular bodies 12, 14 and 16, it is necessary to use pressurized water. Since the water supply and circulation device is unnecessary and the outer surface of the condensed tubular resin film 20 is integrally adhered and cured so as to be integral, the damage of the outer skin resin film 20 is prevented and durability is further increased.
