본 발명은 단섬유와 폐우레탄 분말을 이용하여 흡음재 패널을 제조하는 시스템에서 단섬유와 폐우레탄분말을 혼합하는 장치에 관한 것이다.The present invention relates to an apparatus for mixing short fibers and waste urethane powder in a system for manufacturing a sound-absorbing panel using short fibers and waste urethane powder.

단섬유와 폐우레탄 분말을 이용하여 흡음재 패널을 제조하는 시스템은 일본국 특개1995-68550호에 개시되어 있다.A system for manufacturing a sound-absorbing panel using short fibers and waste urethane powder is disclosed in Japanese Patent Laid-Open No. 1995-68550.

상기 개시된 흡음재 패널 제조시스템에서는, 연질 우레탄 폼에 천 등의 섬유재가 붙은 상태의 피처리체가 분쇄기에 투입되어 상기 피처리체가 고회전수의 커터 에서 분쇄물로 가공되고, 상기 분쇄물은 블로어에 의해 덕트를 통해 사이클론, 호퍼, 그리고 제1스크류 피더로 보내져 스크류 피더 안에서 교반되고, 섬유재가 붙은 연질 우레탄 폼의 분쇄물, 섬유재, 연질 우레탄 폼의 분쇄물인 거의 3종류의 분쇄물 이 균등하게 제2계량기로 보내진다.In the sound-absorbing panel manufacturing system disclosed above, a target object in a state in which a fiber material such as cloth is attached to a flexible urethane foam is put into a grinder, and the target object is processed into a pulverized product by a high-speed cutter, and the pulverized product is ducted by a blower It is sent to the cyclone, hopper, and the first screw feeder through the cyclone, and is stirred in the screw feeder, and almost three types of pulverized material, which are the pulverized material of flexible urethane foam with fiber material, fiber material, and pulverized material of flexible urethane foam, are evenly distributed in the second meter. is sent to

이와 동시에 제2스크류 공급 장치에 투입된 저융점 폴리에스테르 단섬유는 제2스크류 공급 장치에 의해 제2계량기로 보내진다.At the same time, the low-melting polyester short fibers fed into the second screw feed device are sent to the second meter by the second screw feed device.

제1 및 제2계량기는 양자의 미리 정해진 혼합비에 근거하여 소정량을 덕트 을 통해 혼련 혼합기로 내보내어 지고, 여기서 상기 분쇄물과 저융점 폴리에스테르 단섬유는 혼련되어 덕트을 통해 제3스크류피더, 제3계량기로 보내진다. 제3계량기 는 성형기의 형틀에 따라 조정된 1회분의 혼합물을 내보낸다.The first and second meters are fed a predetermined amount to a kneading mixer through a duct based on a predetermined mixing ratio of both, wherein the pulverized product and short low-melting polyester fibers are kneaded through a duct through a third screw feeder and a third meter. 3 is sent to the meter. The third meter delivers a batch of mixture adjusted according to the mold of the molding machine.

성형기는 이 혼합물을 형틀사이에 끼워 핫 프레스, 즉 가열온도 100℃~140℃를 가함과 동시에 1~400kg/cm2의 범위에서 가압한다. 이 가열온도는 100℃~140℃가 최적으로 이루어져 저융점 폴리에스테르 단섬유가 연화되지만, 연질우레탄폼 3는 유동화하지 않는 온도이다. 또한 가압력은 높을수록 밀도가 증가하고 강도가 올라가는 추세인데 밀도를 높이면 열전도율이 올라가 보온력이 저하되므로 최종 성형품의 용도에 따른 가압력을 선택하게 된다.The molding machine puts this mixture between the molds and presses it in the range of 1 to 400 kg/cm2 while applying a hot press, that is, a heating temperature of 100°C to 140°C. This heating temperature is optimally made between 100°C and 140°C, so that the low-melting polyester short fibers are softened, but the flexible polyurethane foam 3 is not fluidized. In addition, as the pressing force increases, the density increases and the strength increases. If the density is increased, the thermal conductivity increases and the thermal insulation power decreases. Therefore, the pressing force is selected according to the purpose of the final molded product.

이렇게 핫프레스 처리된 예비성형품은 컨베이어로 반송되어 그 공정 중에 냉각팬에 의해 냉각되어 받침대상에서 절단날에 의해 소정의 형상으로 절단 가공되어 최종성형품를 얻을 수 있다. The hot-pressed preform is transferred to a conveyor, cooled by a cooling fan during the process, and cut into a predetermined shape by a cutting blade on a pedestal to obtain a final molded product.

상기 최종성형품은 각종 제품의 부재로 이용할 수 있으며, 예를 들면 단열재, 심재로서 즉 파티션의 보드, 파티션의 뒷면, 또 카펫의 뒷면질재 등에 사용할 수 있다. The final molded product can be used as a member of various products, and for example, can be used as a heat insulating material, a core material, that is, a board of a partition, a back side of a partition, and a back material of a carpet.

상기와 같이 구성되고 작용되는 상기 개시된 흡음재 패널 제조시스템에서는, 폐우레탄분말이 스크류 공급장치에 의해 그리고 단섬유가 스크류 피더에 의해 혼련 혼합기에 의해 투입되어 상기 혼련 혼합기에 내장된 혼합 날개에 의해 혼합되지만, 폐우레탄분말은 알갱이 형상으로 되어 있고, 단섬유는 길다란 형상으로 되어 있은 상태에서 이들 간에 중량이 상이하기 때문에, 골고루 혼합되지 않는다는 문제점이 있다. In the disclosed sound absorbing material panel manufacturing system configured and operated as described above, the waste urethane powder is input by the kneading mixer by the screw feeder and the short fibers are mixed by the mixing blade built into the kneading mixer, but , The waste urethane powder is in the form of granules, and the short fibers have a problem in that they are not evenly mixed because the weights are different between them in the state that they are in a long shape.

이러한 문제점을 해결하기 위해, 하나의 챔버의 상단에 두개의 입구를 형성하고, 두개의 입구 중 하나의 입구를 통하여 기류에 의해 폐우레탄분말을 상기 하나의 챔버 내에 투입하고, 그리고 다른 하나의 입구를 통하여 기류에 의해 단섬유를 상기 하나의 챔버 내에 투입하여 상기 하나의 챔버 내에서 폐우레탄분말과 단섬유를 서로 혼합한 다음, 벨트 컨베이어의 벨트 상에 배출시키는 방안이 고려될 수 있지만, 이러한 방안도, 폐우레탄분말과 단섬유 간에 형상과 중량이 서로 상이하기 때문에, 폐우레탄분말과 단섬유가 각각 한 쪽으로 몰려 있어, 폐우레탄분말과 단섬유이 골고루 혼합되지 않는다는 문제점이 있다. In order to solve this problem, two inlets are formed at the top of one chamber, and the waste urethane powder is put into the one chamber by an airflow through one of the two inlets, and the other inlet is A method of injecting short fibers into the one chamber by an airflow through the one chamber, mixing the waste urethane powder and the short fibers with each other, and then discharging them on the belt of the belt conveyor may be considered, but this method also , Since the shape and weight are different between the waste urethane powder and the short fibers, the waste urethane powder and the short fibers are concentrated to one side, respectively, and there is a problem that the waste urethane powder and the short fibers are not evenly mixed.

본 발명은 상기된 문제점을 해결하는 것에 과제를 가진다.The present invention has a problem in solving the above problems.

본 발명은, 구매한 단섬유를 제1호퍼에 저장하고, 그리고 폐우레탄 분말을 제2호퍼에 저장한 상태에서, 기류에 의해 이들을 제1챔버와 제2챔버에 공급하면서, 제1챔버에 공급된 단섬유를 제1챔버 하단에 구비된 제1공급롤러를 통하여 자연낙하에 의해 벨트 컨베이어 상에 공급하고, 그리고 제2챔버에 공급된 폐우레탄 분말을, 제2챔버 하단에 구비된 제2공급롤러를 통하여 자연낙하에 의해, 상기 컨베이어에 얹어진 단섬유층 상에 공급한 다음, 상기 벨트 컨베이어 상에 얹어져서 단섬유층과 폐우레탄 층이 서로 적층된 층을 외주면에 복수개의 핀이 달린 찢음 드럼에 의해 이들을 무작위로 찢어 분리하여 수렴관형부에 의해 분리된 층을 혼합하게 함으로써 상기 과제를 해결할 수 있다In the present invention, the purchased short fibers are stored in the first hopper, and in a state in which the waste urethane powder is stored in the second hopper, while supplying them to the first chamber and the second chamber by airflow, the first chamber is supplied The short fibers are supplied on the belt conveyor by natural fall through the first supply roller provided at the lower end of the first chamber, and the waste urethane powder supplied to the second chamber is supplied to the second supply provided at the lower end of the second chamber. By natural fall through a roller, it is supplied on the short fiber layer mounted on the conveyor, and then placed on the belt conveyor, and the layer in which the short fiber layer and the waste urethane layer are laminated on each other to a tear drum with a plurality of pins on the outer circumferential surface. The above problem can be solved by randomly tearing them apart and mixing the layers separated by the converging tubular part.

본 발명은, 상기와 같은 과제해결수단에 의해, 3차원적으로 단섬유와 폐우레탄 분말이 골고루 썩이게 되어 성형된 흡음패널에 단섬유와 폐우레탄 분말이 전체적으로 밸런스 있게 분포되게 할 수 있다.According to the present invention, the short fibers and the waste urethane powder are uniformly rotted three-dimensionally by the problem solving means as described above, so that the short fibers and the waste urethane powder are evenly distributed throughout the sound-absorbing panel molded.
