Description

다겹 솜판 및 그 제조방법 {Many folds and its manufacturing method}Multi-layered cotton sheet and its manufacturing method {Many folds and its manufacturing method}

본 발명은 다겹 솜판 및 그 제조방법에 관한 것으로 보다 구체적으로는 평판형으로 된 상·하 외피 사이에 볼 형상의 솜으로 내부가 채워진 파형판 심재를 끼워넣어 구성된 다겹 솜판과 이를 일관된 공정으로 제조할 수 있는 방법에 관한 것이다.The present invention relates to a multi-ply cotton sheet and a method of manufacturing the same. More specifically, a multi-ply cotton sheet and a consistent shape is formed by inserting a corrugated plate core material filled with a ball-shaped cotton between the upper and lower shells of a flat plate type. It is about how it can be.

의복이나 침구등의 충전물로서 주로 사용되는 솜은 보온성과 함께 탄력성과 복원력을 동시에 가지고 있기때문에 소정두께의 솜판으로 제작하여 의류나 침구등에 내장하여 많이 사용되고 있는데 이러한 솜판은 탄력성과 복원력이 쉽게 떨어지는 단점이 있기때문에 솜섬유에 아크릴수지를 도포하여 가공하므로서 탄력성과 복원력이 보다 오래 유지되도록 하였으나 이 역시 일정기간 사용하게되면 아크릴수지가 마모되어서 솜섬유에서 떨어지므로서 솜판의 탄력성과 복원력이 떨어져 압력을 받으면 솜판이 납작해져버리는 문제점이 있었다.Cotton, which is mainly used as a filling material for clothes or bedding, has both warmth and elasticity and resilience at the same time, so it is made of cotton with a predetermined thickness and used in clothes or bedding. Because it is processed by applying acrylic resin to the cotton fiber, the elasticity and restoring force is maintained for a longer time.However, if it is used for a certain period of time, the acrylic resin will wear out and fall off the cotton fiber. There was a problem that the plate flattened.

이러한 문제점을 해결하기 위하여 개발된 것이 상·하 외피사이에 물결형 주름을 가진 파형판으로 된 심재를 개입하여 우수한 탄력성과 복원력을 오래 유지할 수 있는 솜판을 제조하는 방법이 개발되었으나 이 파형판으로 된 심재의 탄력성이 약하여 오랜 기간 사용하면 심재가 쉽게 누워버리거나 형태가 찌그러져 탄력성이 쉽게 떨어지므로서 솜판의 탄력성이 약화되고 두께가 얇아지는 문제점이 있었다.In order to solve this problem, a method of manufacturing a cotton plate that can maintain excellent elasticity and resilience for a long time has been developed by interposing a core material made of a corrugated plate with wavy wrinkles between the upper and lower outer shells. When the elasticity of the core material is weak and used for a long time, the core material is easily laid down or distorted in shape so that the elasticity is easily dropped, thereby reducing the elasticity of the cotton plate and thinning the thickness.

본 발명은 위와 같은 종래의 문제점을 해소하기 위하여 개발한 것으로 상·하 외피 사이에 개입되는 파형판으로 된 심재의 내부에 볼 형상의 솜을 채워넣으므로서 심재가 높은 탄력을 오래동안 유지하고 그 형태가 쉽게 변형되지 않도록 함과 동시에 이러한 구성으로 된 솜판을 일관된 공정으로 연속 제조할 수 있게 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention was developed in order to solve the above-mentioned conventional problems, while filling the ball-shaped cotton inside the core of the corrugated plate intervening between the upper and lower outer shell, the core material maintains high elasticity for a long time and its The shape is not easily deformed, and at the same time it is possible to continuously manufacture the cotton plate having such a configuration in a consistent process as described in detail by the accompanying drawings as follows.

(1) comprises a shell supply part 40, a core material supply part 50, a joint part 70 and a cooling part 80 in order to manufacture such a multi-ply cotton plate (1), in the skin supply part 40 Dividing into upper and lower outer shells (2) and (2 '), and then transferring them in different directions using the conveying conveyors (41) and (41'), and then entering between the thermal joining rollers (71) of the joint (70). In the core material supply unit 50, the ball-shaped cotton ball 60c is provided between the upper plate supply unit 51 and the lower plate supply unit 52 so that the ball-shaped cotton balls 3c are filled between the upper plate 3a and the lower plate 3b. After pressurized The corrugated plate formed with the ups and downs 301 by the corrugation molding machine 54 located in the place where the core material 3 which passed the rudder 53 is high, is conveyed by the conveyance belt 54a, and the row of the junction part 70 is carried out. After the upper and lower outer shells (2) (2 ') and the core material (3) are joined by the thermal joining roller (71) while intervening between the upper and lower outer shells (2) (2') entering between the joining rollers (71). Passing through the cooling unit 80 is a configuration to make a multi-ply cotton plate (1).

이와 같이 된 본 발명은 솜판(1)의 상·하 외피(2)(2')사이에 개입되는 심재(3)를 상판(3a)과 하판(3b)으로 구성하고 그 상판(3a)과 하판(3b) 사이에는 콩알 크기 정도의 볼 형상으로 된 솜(3c)을 채워넣으므로서 심재(3)가 3중 구성체로 이루어져 탄력성과 보온성이 크게 강화될 뿐 만 아니라 기복부(301)가 형성되는 파형판으로 심재(3)를 형성하므로서 기복부(301) 사이의 공간으로 통풍이 원활이 이루어지며 이와 함께 심재(3)의 상판(3a)과 하판(3b) 사이에 채워진 볼 형상의 솜(3c) 간에도 미세한 공간이 확보되어 이 공간들이 원활한 통풍을 돕게 되며 이러한 심재(3)를 상·하 외피(2)(2') 사이에 개입하여 솜판(1)을 제조하므로서 솜판(1)이 탄력성이 크게 강화될 뿐 만 아니라 외부의 압력을 받은 후에도 심재(3)의 강화된 탄력성에 의해 솜판(1)의 복원력이 강화되기 때문에 외부에서 압력이 가해져도 솜판(1)의 복원력에 의해 일정한 두께를 오랫동안 유지할 수 있게 되는 것이다.According to the present invention, the core 3 interposed between the upper and lower shells 2 and 2 'of the cotton plate 1 is composed of an upper plate 3a and a lower plate 3b, and the upper plate 3a and the lower plate. Filling the ball-like ball (3c) of the size of the bean ball (3b) between the core material (3) is made up of a triple structure not only greatly enhances the elasticity and warmth, but also the relief portion 301 is formed Since the core 3 is formed of a corrugated plate, the air is smoothly ventilated into the space between the ups and downs 301, and the ball-shaped cotton 3c filled between the upper plate 3a and the lower plate 3b of the core 3 is formed. The micro spaces are also secured between the two to help smooth ventilation, and the cotton plate 1 is made elastic by intervening the core material 3 between the upper and lower outer shells 2 and 2 '. Not only is it greatly strengthened, but also because the resilience of the cotton plate 1 is strengthened by the reinforced elasticity of the core 3 even after being subjected to external pressure. Even if pressure is applied from the outside, it is possible to maintain a constant thickness for a long time by the restoring force of the cotton plate 1.

한편, 심재(3)를 제조함에 있어서 심재공급부(50)의 상판공급부(51)와 하판공급부(52) 사이에 볼솜공급부(60)를 마련하여 상판(3a)과 하판(3b)이 각각 공급될때 하판(3b)의 윗 면에는 볼솜공급부(60)에서 배출되는 볼 형상의 솜(3c)이 뿌려진 후 가압로울러(53)에서 볼 형상의 솜(3c)이 뿌려진 하판(3b)과 상판(3a)을 맞대어져 가압되면 솜이 가지는 엉키는 성질때문에 상판(3a)과 하판(3b) 사이에 볼 형상의솜(3c)가 채워진 판 형상의 심재(3)가 완성되며 이러한 판 형상의 심재(3)를 콘베이어를 이용하여 높은곳에 위치한 파형성형기(54)로 공급하여 일정한 진폭으로 왕복운동하는 파형성형기(54)를 통과시키면서 이송벨트(54a) 사이로 배출시키면 판 형상의 심재(3)가 일정한 간격으로 기복부(301)를 가지는 파형판으로 만들어지게 된다.On the other hand, when manufacturing the core material (3) is provided between the upper plate supply unit 51 and the lower plate supply unit 52 of the core material supply unit 50 when the upper plate (3a) and lower plate (3b) is supplied respectively The upper surface of the lower plate (3b) and the lower plate (3b) and the upper plate (3a) is sprayed with a ball-shaped cotton (3c) sprinkled with a ball-shaped cotton (3c) from the pressure roller (53) after the ball-shaped cotton (3c) discharged from the ball cotton supply unit 60 When pressurized by the pressure, the entangled property of the cotton is completed because of the plate-shaped core material 3 filled with the ball-shaped cotton wool 3c between the upper plate 3a and the lower plate 3b, and the plate-shaped core material 3 is conveyed. By supplying to the corrugator (54) located at a high place and passing between the conveying belt (54a) while passing through the corrugator (54) reciprocating at a constant amplitude plate-shaped core material (3) is the undulation ( 301).

이렇게 파형판으로 만들어진 심재(3)를 콘베이어로 이송시켜 접합부(70)의 열접합로울러(71)사이로 진입되는 상·하 외피(2)(2') 사이로 개입시켜 열접합로울러 (71)를 이용하여 상·하 외피(2)(2')와 심재(3)를 열접합한 후 냉각부(80)를 통과시키므로서 다중 구성체로 이루어진 다겹의 솜판(1)이 만들어 지게 되는 것이다.The core material 3 made of a corrugated plate is transferred to a conveyor to intervene between the upper and lower outer shells 2 and 2 'which enter between the thermal joining rollers 71 of the joining part 70 to use the thermal joining rollers 71. The upper and lower outer shell (2) (2 ') and the core material (3) is thermally bonded and then passed through the cooling unit 80 is made of a multi-layered cotton plate (1) consisting of multiple components.

이와 같이 본 발명은 심재(3)내부에 채워진 볼 형상의 솜(3c)에 의해 심재(3)의 탄력성이 대폭 강화되므로서 솜판(1)이 탄력성이 더욱 우수해질 뿐 만 아니라 복원력과 보온성도 향상되어 양질의 솜판(1)을 얻을 수 있으며 일관된 제조공정을 통하여 대량 생산할 수 있는 이점이 있다.In this way, the present invention is not only because the elasticity of the core material 3 is significantly strengthened by the ball-shaped cotton (3c) filled in the core material 3, not only the elasticity of the cotton plate 1 is more excellent, but also the restoring force and thermal insulation properties are improved. It is possible to obtain a high quality cotton plate (1) and has the advantage of mass production through a consistent manufacturing process.
