The room temperature foam member (3) is effective to block noise and vibration because the foaming rate is 3000% to 4000%.

그러나, 상기 상온 발포재는 의장라인에서 폐단면에 주입하면 너무나 큰 발포율에 의하여 주위의 기능성 홀(HOLE), 즉, 갖가지 의장 트림의 마운팅, 전장 아이어링 마운팅 등의 홀(HOLE)을 뚫고서 폐단면 뿐만 아니라 밖으로 삐져나와 의장 트림과 전장 와이어링 작업이 불가능한 문제점이 있다.However, when the room temperature foam material is injected into the closed section in the design line, the closed section is cut through a hole (HOLE) such as the mounting of various design trims, that is, the mounting of the various design trims, and the total length of the ironing, due to the foaming ratio being too high. In addition, there is a problem that protrudes out of the chair trim and electrical wiring is impossible.

또한, 상기 상온 발포재가 밖으로 삐져나오게 되면 작업자의 옷과 차체 구조물을 오염시켜 조립적인, 상품적인 품질에서의 심각한 저하를 초래할 수 있는 문제점이 있다.In addition, if the room temperature foaming material is protruded out there is a problem that can cause a serious degradation in the assembly quality, product quality to contaminate the clothes and body structure of the worker.

그리고, 상온 발포재의 탁월한 발포율 때문에 원하는 수준의 발포 범위를 산정하기 힘들어서, 이의 해결을 위한 상당한 노력과 시간이 필요한 문제점이 있다.And, because of the excellent foaming rate of the room temperature foaming material, it is difficult to calculate the desired level of foaming range, there is a problem that requires a considerable effort and time for its solution.

본 발명은 상기 전술한 바와 같은 문제점들을 해결하기 위해 창출된 것으로서, 발포재의 충진후 외부로 유출되지 못하도록 하며, 원하는 수준의 발포 범위를 산정할 수 있는 상온 발포재 충진장치를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the problems as described above, the object of the present invention is to provide a room temperature foam material filling apparatus that can prevent the outflow to the outside after the filling of the foam material, the foaming range of the desired level can be calculated. .
