Description

외피재가 부착된 단열재 제조방법Insulation Material Manufacturing Method
본 발명은 선박 등의 격실에 대한 단열을 위한 단열재의 제조방법에 관련되는 기술이다.The present invention is a technique related to a method for producing a heat insulator for heat insulation for compartments such as ships.
에너지 효율 향상을 위한 다양한 단열재들이 사용되고 있으며, 대표적으로 스티로폼이나 미네랄울, 글라스울 등을 이용한 단열재가 많이 사용된다. 주택이나 아파트 등의 시공시에는 스티로폼과 같은 단열재가 많이 사용되고 있으나, 대형 선박의 경우 철판을 이용하여 구분되는 격실을 구성하기 때문에 격벽 외면에 단열재를 붙이도록 한다.최소 규격으로 판상체로 제공되는 단열재를 격벽의 형상에 맞게 커팅하여 부착하여야 하므로 단열재의 커팅이 요구된다.특히, 대형 선박의 경우 강성을 유지하기 위해 격벽 중간중간에 ㄱ 자 형태로 돌출되는 스티프너(stiffner)가 많이 설치된다. 이러한 스티프너 부분도 단열재로 감싸야만 단열성을 확보할 수 있다. 도 1은 선박의 스티프너 및 단열재를 이용한 스티프너의 단열구조를 보여주는 예시도이다. 스티프너(10)를 감싸도록 ㄷ 자 형태로 성형되는 메인단열재(20)와 ㄱ 자 스티프너(10)의 홈을 채우는 채움단열재(30)를 이용하여 스티프너(10)에 대한 단열이 이루어지도록 한다. 이러한 단열재를 만들기 위해서는 필수적으로 사각판상 형상으로 제공되는 단열판재를 적절히 커팅한 후 외피재를 붙여서 일체화된 단열재를 제조하게 된다. 단열판재를 커팅하여 소정의 단열소재를 만든 후 각 단열소재는 외피재를 부착하게 되는데, 외피재에 접착제를 도포한 후 단열소재를 붙이는 공정이 필요하며, 기존의 작업방식에서는 작업자들의 수작업에 의한 생산이 이루어졌으므로 생산성이 지극히 낮고 제품의 품질도 편차가 심하게 되는 문제점이 있었다.Various insulation materials are used to improve energy efficiency, and typically, insulation materials using styrofoam, mineral wool, and glass wool are used. Insulation materials such as styrofoam are often used in the construction of houses or apartments, but in the case of large ships, the partitions are separated by steel plates, so attach the insulation to the outside of the bulkhead. In order to maintain the rigidity, a large number of stiffeners protruding in the form of an "A" in the middle of the bulkhead are installed in order to maintain rigidity. This stiffener portion must also be wrapped with insulation to ensure insulation. 1 is an exemplary view showing an insulating structure of a stiffener using a stiffener and a heat insulating material of a ship. Insulation to the stiffener 10 is made by using the main insulating material 20 formed in the c-shape to surround the stiffener 10 and the filling insulating material 30 filling the groove of the a-shaped stiffener 10. In order to make such a heat insulating material is essentially cut the heat insulating plate provided in the shape of a square plate shape appropriately to produce an integrated heat insulating material by attaching the outer cover material. After cutting the insulation board to make a predetermined insulation material, each insulation material is attached to the outer cover material, which is required to apply the adhesive to the outer cover material and then attach the insulating material.

이하 본 발명에 의한 외피재가 부착된 단열재 제조방법에 대해 보다 상세한 설명을 하도록 하며, 첨부되는 도면을 참조하는 것으로 한다. 단, 제시되는 도면 및 이에 대한 구체적인 설명은 본 발명의 기술적 사상에 따른 하나의 실시 가능한 예를 설명하는 것인 바, 본 발명의 기술적 보호범위가 이에 한정되는 것은 아니다. 본 발명에 의한 외피재가 부착된 단열재 제조방법은 다양한 사이즈 및 형태를 갖는 단열재의 제조에 활용될 수 있으며, 단순한 하나의 판상체로 이루어지는 단열재 일 수도 있고, 접히는 ㄷ 자 혹은 ㄴ 자 형상의 단열재를 제조할 수도 있다. 이하 설명에서 세트단위라는 것은 2개 이상의 단열소재로 이루어져 ㄴ, ㄷ 자 형태로 접힐 수 있는 것들의 조합을 의미한다. 2개 이상의 단열소재가 인접하여 배치되어 하나의 세트단위를 이루는 것은 하나의 단열재로 인식된다. 도 2는 본 발명에 따른 외피재가 부착된 단열재 제조방법의 작업 순서도이며, 도 3은 외피재가 부착된 단열재 제조방법의 개략적인 공정도이며, 도 4는 메인접착제도포롤과 보조접착제도포롤의 표면에 포집홈이 형성된 것을 보여주는 사시도이며, 도 5는 본 발명의 제1실시예에 의한 외피재 커팅단계가 이루어지는 모식도이고, 도 6은 본 발명의 제2실시예에 의한 외피재 커팅단계가 이루어지는 모식도를 나타낸 것이다. 본 발명은 도 2 및 도 3과 같이 컷팅단계(S100), 접착제 도포단계(S200), 가접합단계(S300), 외피재 커팅단계(S400), 외피재 오버랩단계(S500), 압착단계(S600), 건조단계(S700)를 포함하여 이루어질 수 있다. 컷팅단계(S100)에서는 외피재(100)가 부착된 단열재(I)를 제조하기 위해 소정의 단열재 원판(10)을 원하는 폭 및 절단각도로 잘라 필요한 단열소재(200)를 만들도록 하는 것이다. 언급하였듯이 만들고자 하는 외피재(100)가 부착된 단열재(I)는 한 피스의 사각판상체일 수도 있고, 컷팅 각도는 수직방향일 수도 있고, 45도 각도로 컷팅이 될 수도 있다. 또한, 외피재가 부착된 단열재(I)는 2개 이상의 단열소재(200)의 연속적인 배치로 이루어질 수도 있다. 본 발명의 제1실시예에서는 하나의 사각 판상체 각각의 단열소재(200)가 하나의 단열재(I)를 이루는 경우를 예로 하여 설명하도록 한다. 컷팅단계(S100) 다음으로 접착제 도포단계(S200)가 이어진다. 접착제 도포단계(S200)는 롤 상으로 감겨진 외피재(100)가 풀리면서 접착제도포롤(300)을 통과하도록 하여 그 과정 중에 외피재(100)의 내측면에 접착제(20)가 도포될 수 있도록 하는 것이다. 외피재(100)는 필름과 같은 것으로 알루미늄 소재의 얇은 부재로 단열소재(200)의 표면에 부착됨으로써 표면강도를 높여주게 된다. 단열소재(200)는 미네랄울이나 글라스울 등 기존에 알려진 단열소재를 활용할 수 있다. 롤 상의 외피재(100)에 연속적으로 접착제(20)가 도포되게 해야 하기 때문에 도 3과 같이 접착제 도포단계(S200)는 외피재(100)의 공급이 자동화되고 이 과정 중에 소정의 접착제(20)가 고르게 외피재(100)의 내측면에 도포되어야 한다. 외피재(100)에 적정량의 접착제(20)가 도포되어야 불필요한 접착제의 낭비를 줄일 수 있고, 충분한 접착력을 형성시킬 수 있다. 이를 위해 메인접착제도포롤(310)과 보조접착제도포롤(320)을 한 쌍으로 상하로 배치하여 접착제(20)가 공급되어 외피재(100)에 도포될 수 있도록 한다. 구체적으로 액상의 접착제(20)가 수용되는 보관조(400)가 구비되고 보관조(400)에는 소정량의 접착제가 수용되도록 한다. 보관조(400) 내부에 보조접착제도포롤(320)이 설치되고, 보조접착제도포롤(320) 위에 메인접착제도포롤(310)이 마련된다. 보조접착제도포롤(320)과 메인접착제도포롤(310)은 위치 조정을 통해 상호간 간극 조정이 가능하도록 하며, 양자는 상호 그 외면이 접촉될 수도 있고 미세한 갭을 두고 배치될 수도 있다. 보조접착제도포롤(320)은 보관조(400)에 수용된 접착제와 맞닿아 있어 보조접착제도포롤(320)이 회전하면서 접착제(20)를 그 외면에 묻혀지게 한다. 보조접착제도포롤(320)에 묻은 접착제는 메인접착제도포롤(310) 표면으로 옮겨지게 된다. 더욱 바람직하게 메인접착제도포롤(310)의 외주면에는 소정의 이격 거리를 두고 원형을 이루는 복수의 포집홈(301)이 형성될 수 있으며, 포집홈(301)을 통해 원활하게 접착제(20)의 공급이 이루어지도록 할 수 있다. 그리고 보조접착제도포롤(320)의 외주면에도 동일한 포집홈(301)이 형성되게 할 수 있고, 쌍을 이루어 회전되는 보조접착제도포롤(320)과 메인접착제도포롤(310)로 인해 접착제(20)가 메인접착제도포롤(310)로 옮겨질 때 포집홈(301)으로 인해 보다 원활하게 접착제(20)의 이동이 가능하게 할 수 있다. 메인접착제도포롤(310)에 옮겨 묻은 접착제(20)는 외피재(100)로 접착제(20)가 옮겨져 도포되게 함으로써 접착제가 소진되고, 접착제(20)가 소진된 영역은 회전되어 보조접착제도포롤(320)과 접촉되면서 새로운 접착제가 공급된다. 이러한 과정 중에 포집홈(301)은 접착제(20)의 이송이 효과적으로 이루어질 수 있도록 하는 기능을 하게 된다. 더욱 바람직하게 메인접착제도포롤(310) 및 보조접착제도포롤(320)에 형성되는 포집홈(301)은 메인접착제도포롤(310)과 보조접착제도포롤(320)의 전체 길이 중 좌우 가장자리 영역에 보다 조밀하게 포집홈(301)이 형성되도록 하여 외피재(100)의 가장자리에 대한 접착제(20) 도포가 확실하게 이루어질 수 있도록 한다. 그리고 메인접착제도포롤(310)과 보조접착제도포롤(320)의 가장자리에 형성되는 포집홈(301)은 타 부위보다 폭이 좁게 형성되게 하면서 이웃하는 포집홈(301)의 간격도 좁게 하도록 하여 외피재(100)의 가장자리에 접착제(20)가 고르게 도포될 수 있도록 하는 것이 바람직하다. 다음으로 가접합단계(S300)가 뒤따르고, 접착제(20)가 도포된 외피재(100)는 컨베어(C) 위에 올려진 채 이동하게 되며, 이 과정 중에 접착제(20)가 도포된 외피재(100) 위에 준비된 단열소재(200)를 올려 가접합이 이루어지도록 한다. 컨베어(C)를 타고 이동하는 외피재(100) 위에 소정의 간격을 두고 단열소재(200)를 올려두도록 하며, 단열소재(200)의 두께를 고려하여 적정한 간격으로 단열소재를 배치하도록 한다. 가접합단계(S300) 다음으로 외피재 커팅단계(S400)가 이어지는데, 외피재 커팅단계(S400)에서는 외피재(100)에 가접합된 단열소재(200)를 세트단위를 이루도록 외피재(100)를 커팅하도록 하며, 특히 전방 세트(FS)의 후단과 후방 세트(RS)의 전단과의 거리를 측정하여 그 중간부분을 커팅하도록 한다. 본 제1실시예의 경우 하나의 세트단위(FS,RS)는 한 장의 단열소재(200)가 한 세트단위가 되는 것인 바, 소정의 이격거리를 형성하면서 외피재(100)에 가접합되어 이동되는 이웃하는 단열소재(200)간 이격거리의 중간 부분을 자르도록 한다. 이를 위해 외피재(100)가 올려져 이동되는 컨베어(C)의 끝 부분에 소정의 커터(500)가 마련되며, 커터(500)는 외피재(100)의 폭방향을 가로지르면서 외피재(100)를 자르게 되고, 이웃하는 단열소재(200)간 이격거리의 중간 위치를 커팅되게 한다. 보다 구체적으로 이웃하는 단열소재(200)간 이격거리의 중간 위치를 자르도록 하기 위해, 광센서(600)를 이용하여 이격거리를 산출하도록 한다. 광센서(600)는 외피재(100)가 이동하는 컨베어(C)의 일측에 마련되며, 외피재(100)에 가접합된 단열소재(200)의 유무를 파악하게 된다. 단열소재(200)들은 소정의 이격거리를 두고 외피재(100)에 부착된 상태이며, 단열소재(200)는 외피재(100)에 비해 두꺼운 두께를 가지고 있기 때문에 외피재(100)는 인식을 못하고 단열소재(200)의 전단과 후단을 인식할 수 있다. 예를 들어 도 5와 같이 컨베어(C)를 타고 단열소재(200)가 이동하게 되면 제1단열소재(210)가 가장 먼저 광센서(600)를 통과하게 되는데, 이때 광센서(600)는 제1단열소재(210)의 시작점인 전단을 인식하여 제1센싱신호를 발생시키며, 이어서 제1단열소재(210)의 끝부분인 후단을 인식하여 제2센싱신호를 발생시키며, 다음으로 제2단열소재(220)의 전단을 인식하여 제3센싱신호를 발생시키게 된다. 제1단열소재(210)와 제2단열소재(220)는 소정의 이격거리를 두고 있기 때문에 제2센싱신호와 제3센싱신호 상호간에는 시간차가 있게 되며, 이 시간차를 이용하여 전방세트(제1단열소재)(FS,210) 후단과 후방세트(제2단열소재)(RS,220) 전단과의 거리를 계산할 수 있다. 컨베어(C)의 이동속도는 정해져 있고, 제2센싱신호와 제3센싱신호의 시간차가 존재하므로 자동 연산을 통해 제1단열소재(210)와 제2단열소재(220)간 거리가 계산된다. 한편, 광센서(600) 보다 앞쪽에 커터(500)가 설치되고, 광센서(600)와 커터(500)간 거리는 변하지 않는 절대거리를 가지게 된다. 따라서 이러한 정보들의 조합을 통해 커터(500)의 직하방에 전방세트(FS)의 후단과 후방세트(RS)의 전단과의 거리 중간지점이 위치되게 컨베어(C)의 구동을 제어하여 일시적으로 컨베어의 구동이 정지되게 한 다음 커터(500)가 작동되게 하여 외피재(100)를 커팅하도록 한다. 외피재(100)의 컷팅이 이루어지면, 제1단열소재(210)는 연이어 배치되는 또 다른 컨베어를 타고 이동되며, 외피재 오버랩단계(S500)가 연이어 이루어진다. 외피재 오버랩단계(S500)에서는 커팅된 외피재(100)의 끝단을 접어서 단열소재(200)의 측면 및 상면 일부를 덮도록 부착시키도록 한다. 단열소재(200)의 전단과 후단 일부 상면을 덮을 수 있을 정도면 충분하다. 이웃하게 외피재(100)에 가접합되는 단열소재(200)들의 이격거리에 따라 커팅된 외피재(100)가 단열소재(200) 상면을 덮는 면적이 결정된다. *외피재 오버랩단계(S500) 다음은 압착단계(S600)로서, 압착단계(S600)에서는 단열소재(200) 상면을 눌러 외피재(100)와 단열소재(200)간 접합력이 증대되도록 한다. 압착단계(S600)는 가접합 상태인 외피재(100)와 단열소재(200)를 컨베어(C)를 따라 이동되게 하면서 상측에서 가압롤러(700)로 눌러 주도록 하는 방식으로 압착이 이루어지도록 할 수 있다. 압착단계(S600) 후 건조단계(S700)가 뒤따르는데, 건조단계(S700)는 터널식 건조로를 통해 외피재(100)와 단열소재(200)를 지나가도록 하여 접착제(20)가 경화되게 유도하는 것이다. 터널식 건조로는 소정의 열풍이 송풍되어 적정 온도 분위기를 유지하도록 한다. 건조단계(S700)를 거치게 되면 접착제(20)는 빠르게 경화되어 가접합 상태였던 외피재(100)와 단열소재(200)의 접합력은 증대된다. 한편, 건조단계(S700) 후 상온건조단계(S800)가 이어지도록 함이 바람직하다. 상온건조단계(S800)에서는 팬을 이용하여 송풍을 공급하여 건조단계를 거치면서 가열된 단열소재, 외피재 및 접착제를 냉각시키면서 보다 빠른 건조가 이루어지도록 한다. 필요에 따라서는 완성된 단열재를 개별로 포장하도록 하는 포장단계(S900)가 이어지도록 할 수 있다. 포장단계(S900)에서는 성형이 완료된 단열재를 비닐로 감싸 포장하도록 하여 즉시 출고가 가능하도록 한다. 이하 본 발명의 제2실시예에 대해 개략적으로 설명하도록 한다. 언급한 바와 같이 단열소재(200)는 2개 이상의 조합에 의해 하나의 세트단위를 구성하는 경우도 있는 바, 이러한 경우에 대해 설명하도록 한다. 도 6과 같이 외피재(100) 위에 단열소재(200)가 배치되되, 3개의 단열소재가 인접하여 배치되어 한 세트단위를 이루게 되고, 이런 방식으로 연속적으로 복수의 세트단위(FS,RS)들이 외피재(100)에 가접합 상태로 부착된 채 컨베어(C)를 따라 이동하게 된다. 특히, 한 세트단위를 이루는 3개의 단열소재는 도시된 바와 같이 45도 각도로 끝단이 경사지게 커팅되는 경우도 있다. 이런 경우 광센서(600)에 의한 단열소재(200)의 인식패턴이 달라지게 되며, 세트단위의 구별에 문제가 발생될 수 있다. 이를 방지하기 위해 바람직하게 광센서(600)는 컨베어(C)의 상측에 배치되어 45도 각도로 경사지게 커팅된 단열소재(200)의 끝단을 인식할 수 있도록 한다. 물론, 광센서(600)는 제1실시예와 같은 단열소재(200)의 측면을 향해 설치되어 단열소재의 측면을 통해 인식되게 할 수 있다. 이런 경우에는 광센서(600)가 V자 형태를 이루는 커팅면 간 거리가 발생되어 이 부분을 세트단위(FS,RS)간 이격거리로 인식할 수 있다. 이를 방지하기 위해 광센서(600)에 의해 인식되는 어떠한 이격거리가 2T+α보다 작은 경우는 하나의 세트단위에 속하는 것으로 판단하여 센싱신호로 입력되지 않도록 프로그래밍 하도록 한다. 여기서, "T" 는 단열소재(200)의 두께를 의미하며, "α" 는 한 세트단위를 이루는 이웃하는 단열소재간 거리를 의미한다. "α"는 필요에 따라 부여할 수 있는 수치이며, 사용시 접히는 것을 고려한 여유분으로써 0mm 내지 5mm 정도로 부여될 수 있다. 인식의 안정성을 위해 광센서(600)의 센싱위치는 단열소재(200)의 두께 기준 대략 중간 정도 위치를 인식하도록 하며, 이런 경우 이웃하는 단열소재간 V 자 구간의 이격거리는 2T+α 보다 작을 것이다. 제2실시예의 경우 하나의 세트단위를 이루는 전방세트(FS) 제1단열소재(210), 제2단열소재(220), 제3단열소재(230)로 이루어지므로, 광센서(600)는 제1단열소재(210)의 시작점인 전단을 인식하여 제1센싱신호를 발생시키게 되고, 제1단열소재(210)와 제2단열소재(220)에 의해 형성된 V 자 홈 사이의 거리는 2T+α보다 작기 때문에 무시되며, 제2단열소재(220)와 제3단열소재(230) 사이의 V 자 홈에 의한 거리 역시 무시되고, 제3단열소재(230)의 끝단인 후단이 인식되어 제2센싱신호를 발생시키고, 연이은 후방세트(RS)를 이루는 제4단열소재(240)의 전단을 인식하여 제3센싱신호를 발생시키게 된다. 이를 통해 전방세트(FS)와 후방세트(RS)간의 거리가 계산되어 그 중간을 컷팅하게 된다. 본 제2실시예는 제1실시예와 그 외 단계는 동일한 바, 이에 대한 설명은 생략하고 제1실시예를 참고하도록 한다.Hereinafter will be described in more detail with respect to the method for manufacturing a heat insulator with an outer cover material according to the present invention, reference to the accompanying drawings.

The method of manufacturing a heat insulating material with an outer cover material according to the present invention can be utilized for the production of heat insulating materials having various sizes and shapes, and may be a heat insulating material consisting of a simple plate-like body, or to manufacture a folding c-shaped or b-shaped insulating material. You may. In the following description, the set unit means a combination of two or more insulation materials that can be folded in a b-shape. Two or more heat insulating materials arranged adjacent to each other to constitute one set unit are regarded as one heat insulating material. Figure 2 is a flow chart of a method of manufacturing a heat insulating material with a skin material according to the present invention, Figure 3 is a schematic process diagram of a method for manufacturing a heat insulating material with a skin material, Figure 4 is a surface of the main adhesive coating roll and the auxiliary adhesive coating roll Figure 5 is a perspective view showing that the collecting groove is formed, Figure 5 is a schematic diagram of the shell material cutting step according to the first embodiment of the present invention, Figure 6 is a schematic diagram of the shell material cutting step according to the second embodiment of the present invention. It is shown. 2 and 3, the present invention is a cutting step (S100), adhesive coating step (S200), temporary bonding step (S300), skin material cutting step (S400), the skin material overlap step (S500), pressing step (S600) ), It may be made, including the drying step (S700). In the cutting step (S100) to cut the predetermined heat insulating plate 10 to the desired width and cutting angle to produce the heat insulating material (I) with the outer cover material 100 is to make the required heat insulating material 200. As mentioned, the insulation I to which the outer cover material 100 to be made is attached may be one piece of a rectangular plate-like body, and the cutting angle may be vertical or may be cut at an angle of 45 degrees. In addition, the insulating material (I) having the outer cover material may be formed of a continuous arrangement of two or more insulating materials (200). In the first embodiment of the present invention will be described by taking an example in which the heat insulating material 200 of each of the rectangular plate-like body forms a single heat insulating material (I). The cutting step (S100) is followed by the adhesive coating step (S200). Adhesive coating step (S200) is to pass through the adhesive coating roll 300 while the outer shell material 100 wound on the roll to the adhesive 20 can be applied to the inner surface of the outer shell material 100 during the process. To ensure that The outer cover material 100 is like a film and is attached to the surface of the heat insulating material 200 as a thin member of aluminum material to increase the surface strength. The thermal insulation material 200 may utilize a conventional thermal insulation material such as mineral wool or glass wool. Since the adhesive 20 must be continuously applied to the envelope 100 on the roll, as shown in FIG. 3, the adhesive application step S200 is automated to supply the envelope 100 and a predetermined adhesive 20 is in the process. Should be evenly applied to the inner surface of the shell material (100). When the appropriate amount of adhesive 20 is applied to the outer cover material 100, unnecessary waste of adhesive may be reduced and sufficient adhesive force may be formed. To this end, the main adhesive coating cloth roll 310 and the auxiliary adhesive coating cloth roll 320 are disposed up and down in a pair so that the adhesive 20 may be supplied and applied to the outer cover material 100. Specifically, the storage tank 400 is provided to accommodate the liquid adhesive 20 and the storage tank 400 to accommodate a predetermined amount of the adhesive. The auxiliary adhesive coating cloth roll 320 is installed in the storage tank 400, and the main adhesive coating cloth roll 310 is provided on the auxiliary adhesive coating cloth roll 320. The auxiliary adhesive coating fabric 320 and the main adhesive coating fabric 310 may be adjusted to each other through position adjustment, and both of them may be in contact with each other or may be disposed with a fine gap. The auxiliary adhesive coating cloth roll 320 is in contact with the adhesive contained in the storage tank 400 so that the auxiliary adhesive coating cloth roll 320 rotates so that the adhesive 20 is buried on its outer surface. The adhesive on the auxiliary adhesive cloth roll 320 is transferred to the surface of the main adhesive cloth roll 310. More preferably, a plurality of collecting grooves 301 may be formed on the outer circumferential surface of the main adhesive agent cloth roll 310 at a predetermined distance, and the adhesive 20 may be smoothly supplied through the collecting groove 301. This can be done. The same collecting grooves 301 may be formed on the outer circumferential surface of the auxiliary adhesive coating roll 320, and the adhesive 20 is caused by the auxiliary adhesive coating roll 320 and the main adhesive coating roll 310 which rotate in pairs. When the main adhesive agent is also moved to the cloth roll 310, the collection groove 301 may enable the movement of the adhesive 20 more smoothly. The adhesive 20 transferred to the main adhesive coating cloth 310 is exhausted by causing the adhesive 20 to be transferred and applied to the outer cover material 100, and the area where the adhesive 20 is exhausted is rotated to support the auxiliary adhesive coating roll. New adhesive is supplied in contact with 320. During this process, the collecting groove 301 has a function of making the transfer of the adhesive 20 effective. More preferably, the collecting grooves 301 formed in the main adhesive drawing cloth roll 310 and the auxiliary adhesive drawing cloth roll 320 are formed at left and right edge regions of the entire lengths of the main adhesive drawing cloth roll 310 and the auxiliary adhesive drawing cloth roll 320. The collection groove 301 is more densely formed so that the adhesive 20 can be reliably applied to the edge of the envelope 100. In addition, the collecting groove 301 formed at the edges of the main adhesive drawing cloth roll 310 and the auxiliary adhesive drawing cloth roll 320 has a narrower width than other portions, and also narrows the interval between neighboring collecting grooves 301. It is desirable to allow the adhesive 20 to be evenly applied to the edge of the ash 100. Next, the temporary bonding step (S300) is followed, the outer shell material 100 is coated with the adhesive 20 is moved on the conveyor (C), the outer shell material coated with the adhesive 20 during this process ( 100) on the prepared insulation material 200 is to be made temporary bonding. The insulating material 200 is placed on the outer cover 100 moving in the conveyor (C) at a predetermined interval, and the insulating material is disposed at an appropriate interval in consideration of the thickness of the insulating material 200. Temporary splicing step (S300) is followed by the outer skin cutting step (S400), the outer skin cutting step (S400) the outer shell material 100 to form a set unit of the heat insulating material 200 temporarily bonded to the outer shell material (100) In particular, the distance between the rear end of the front set (FS) and the front end of the rear set (RS) is measured to cut the middle portion thereof. In the case of the first embodiment, one set unit (FS, RS) is a single unit of the heat insulating material 200 is a set unit bar, while forming a predetermined distance is temporarily bonded to the outer shell material 100 to move Cut the middle portion of the separation distance between the neighboring insulation material 200 to be. To this end, a predetermined cutter 500 is provided at the end of the conveyor C in which the envelope 100 is lifted and moved, and the cutter 500 crosses the width direction of the envelope 100 while covering the envelope ( 100) is cut, and the intermediate position of the separation distance between neighboring insulation material 200 to be cut. More specifically, in order to cut the intermediate position of the separation distance between the adjacent insulating material 200, to calculate the separation distance using the optical sensor 600. The optical sensor 600 is provided at one side of the conveyor C to which the shell material 100 moves, and determines whether the insulation material 200 is temporarily bonded to the shell material 100. The insulation material 200 is attached to the outer cover 100 at a predetermined distance, and the outer insulation 100 has a thicker thickness than the outer cover 100 so that the outer cover 100 is recognized. It can not recognize the front end and the rear end of the insulation material 200. For example, when the heat insulating material 200 is moved on the conveyor C as shown in FIG. 5, the first heat insulating material 210 first passes through the optical sensor 600. A first sensing signal is generated by recognizing the front end of the first insulating material 210, and then a second sensing signal is generated by recognizing a rear end of the first insulating material 210, and then a second insulating signal. The front end of the material 220 is recognized to generate a third sensing signal. Since the first insulation material 210 and the second insulation material 220 have a predetermined distance, there is a time difference between the second sensing signal and the third sensing signal, and the front set (first first) is used by using the time difference. The distance between the rear end of the insulation material (FS, 210) and the front end of the rear set (second insulation material) (RS, 220) can be calculated. Since the moving speed of the conveyor (C) is determined and there is a time difference between the second sensing signal and the third sensing signal, the distance between the first insulating material 210 and the second insulating material 220 is calculated through automatic calculation. On the other hand, the cutter 500 is installed in front of the optical sensor 600, the distance between the optical sensor 600 and the cutter 500 has an absolute distance does not change. Therefore, the combination of such information controls the driving of the conveyor (C) temporarily so that the distance between the rear end of the front set (FS) and the front end of the rear set (RS) is located directly below the cutter (500). After the driving of the stop the cutter 500 is to operate to cut the outer shell material (100). When the cut of the shell material 100 is made, the first insulation material 210 is moved on another conveyor arranged in succession, and the shell material overlap step (S500) is made in succession. In the envelope overlapping step S500, the ends of the cut envelope 100 are folded to be attached to cover a part of the side surface and the upper surface of the insulation material 200. It is enough that the front and rear ends of the heat insulating material 200 can be covered to a part. According to the separation distance of the insulating material 200 to be temporarily bonded to the outer cover material 100 adjacent to the cut surface 100 is an area covering the upper surface of the insulating material 200 is determined. * Envelope overlapping step (S500) Next is a pressing step (S600), in the pressing step (S600) to press the upper surface of the insulating material 200 to increase the bonding force between the outer cover material 100 and the insulating material 200. Squeezing step (S600) may be pressed in such a way to press the outer roller 100 and the heat insulating material 200 in the temporary bonding state while pressing the pressure roller 700 from the upper side while being moved along the conveyor (C). have. After the pressing step (S600) followed by the drying step (S700), the drying step (S700) is to pass through the shell 100 and the heat insulating material 200 through a tunnel-type drying furnace to induce the adhesive 20 to cure. will be. Tunnel type drying furnace is a predetermined hot air is blown to maintain an appropriate temperature atmosphere. Upon passing through the drying step (S700), the adhesive 20 is rapidly cured to increase the bonding force between the outer cover material 100 and the heat insulating material 200 which were temporarily bonded. On the other hand, it is preferable to allow the room temperature drying step (S800) after the drying step (S700). In the normal temperature drying step (S800) while supplying a blower using a fan to go through a drying step while cooling the heated insulation material, shell material and adhesive to achieve a faster drying. If necessary, the packaging step (S900) for packaging the completed insulation can be continued. In the packaging step (S900) it is possible to ship immediately by wrapping the completed insulating material wrapped with vinyl. Hereinafter, a second embodiment of the present invention will be described schematically. As mentioned, the heat insulating material 200 may be configured as one set unit by two or more combinations, and this case will be described. As shown in FIG. 6, the heat insulating material 200 is disposed on the outer cover material 100, and three heat insulating materials are disposed adjacent to each other to form a set unit. In this manner, a plurality of set units (FS, RS) are continuously formed. It is moved along the conveyor (C) while being attached to the outer shell material 100 in a temporary connection state. In particular, the three insulation materials forming a set unit may be cut inclined at the end at a 45 degree angle as shown. In this case, the recognition pattern of the heat insulating material 200 by the optical sensor 600 is changed, and a problem may occur in distinguishing a set unit. In order to prevent this, preferably the optical sensor 600 is disposed on the upper side of the conveyor (C) to recognize the end of the insulation material 200 is inclined at an angle of 45 degrees. Of course, the optical sensor 600 is installed toward the side of the heat insulating material 200 as in the first embodiment can be recognized through the side of the heat insulating material. In this case, the distance between the cutting surfaces of the optical sensor 600 forming the V-shape is generated, and this part may be recognized as a separation distance between the set units FS and RS. In order to prevent this, if any separation distance recognized by the optical sensor 600 is smaller than 2T + α, it is determined to belong to one set unit so that the programming is not input as a sensing signal. Here, "T" means the thickness of the insulating material 200, "α" means the distance between neighboring insulating materials forming a set unit. "α" is a numerical value that can be given as necessary, and may be given as about 0 mm to 5 mm as a margin in consideration of folding in use. For the stability of the recognition, the sensing position of the optical sensor 600 is to recognize the position approximately midway based on the thickness of the insulation material 200, in this case, the separation distance of the V-shaped section between neighboring insulation materials will be less than 2T + α. . In the second embodiment, since the front set (FS) of the first heat insulating material 210, the second heat insulating material 220, and the third heat insulating material 230 forming one set unit, the optical sensor 600 is made of The first sensing signal is generated by recognizing the front end of the first insulation material 210, and the distance between the V-shaped grooves formed by the first insulation material 210 and the second insulation material 220 is greater than 2T + α. It is ignored because it is small, the distance by the V-shaped groove between the second insulation material 220 and the third insulation material 230 is also ignored, and the rear end, which is the end of the third insulation material 230, is recognized and the second sensing signal is recognized. And generate a third sensing signal by recognizing the front end of the fourth insulation material 240 forming the subsequent rear set RS. Through this, the distance between the front set FS and the rear set RS is calculated to cut the middle thereof. The second embodiment is the same as the first embodiment and the other steps, the description thereof will be omitted and reference to the first embodiment.
