The present invention relates to a filing and foaming apparatus for manufacturing a pontoon and a pontoon manufacturing method. The filing and foaming apparatus for manufacturing a pontoon comprises: an insertion pipe which is connected to an injection hole formed on a pontoon main body accommodating a plurality of foamed beads therein; and a steam generator which is connected to the insertion pipe and injects steam at high temperatures into the pontoon main body through the insertion pipe to foam the foamed beads. The insertion pipe is installed to be inserted in the pontoon main body through the injection hole. A plurality of discharge holes through which the steam, supplied by the steam generator, are formed on an outer circumferential side of a portion inserted into the pontoon main body. According to the pontoon manufacturing method and the filing and foaming apparatus for manufacturing a pontoon, the filing and foaming apparatus for manufacturing a pontoon can adjust internal pressure of the pontoon main body in which steam has been injected and thus can prevent the pontoon main body from being exploded by increased internal pressure of the pontoon main body or having a defect when the steam is injected. In addition, according to the pontoon manufacturing method, a state that steam is filled in the pontoon main body is maintained for a predetermined time. Therefore, the foamed beads in the pontoon main body are uniformly foamed, and quality of a product is increased, and a defective rate is reduced.

    본 발명은 폰툰 제조용 충진발포기 및 이를 이용한 폰툰 제조방법에 관한 것으로서, 상기 폰툰 제조용 충진발포기는 내부에 다수의 발포비드가 수용된 폰툰 본체에 형성된 주입구에 연결된 유입관, 상기 유입관에 연결되어 상기 발포비드를 발포시키기 위해 상기 유입관을 통해 상기 폰툰 본체의 내부로 고온의 스팀을 주입하는 스팀발생기를 구비하고, 상기 유입관은 상기 주입구를 통해 상기 폰툰 본체 내부로 인입되게 설치되며, 상기 폰툰 본체 내부로 인입되는 부분의 외주면에 상기 스팀발생기로부터 공급된 스팀이 분사되는 다수의 유출공이 형성되어 있다. 본 발명에 따른 폰툰 제조방법 및 폰툰 제조용 충진발포기는 내부로 스팀이 주입된 폰툰 본체의 내부압력을 조절할 수 있으므로 스팀의 주입에 따라 폰툰 본체 내부압력이 증가하여 폰툰 본체가 폭발하거나 결함이 발생하는 것을 방지한다. 또한, 본 발명에 따른 폰툰 제조방법은 소정 시간동안 스팀이 폰툰 본체 내에 충진된 상태를 유지시키므로 폰툰 본체 내의 발포비드들이 균일하게 발포시켜 제품 품질이 향상되고, 불량률이 감소되는 장점이 있다.
