Description

내관의 열융착을 위한 보조 가열기가 구비된 합성수지관의 제조장치{Device for manufacturing the plastic tube with sub-heater for adhesive inner tube}Apparatus for manufacturing the plastic tube with an auxiliary heater for heat fusion of the inner tube {Device for manufacturing the plastic tube with sub-heater for adhesive inner tube}

본 발명은 지하에 매설되는 광케이블 등의 통신선로 시설을 위한 다수의 내관을 갖는 합성수지관에 관한 것으로, 특히 내관의 열융착을 위한 보조 가열기가 구비된 합성수지관의 제조장치에 관한 것이다.The present invention relates to a synthetic resin pipe having a plurality of inner tubes for communication line facilities, such as optical cables buried underground, and more particularly to a manufacturing apparatus of a synthetic resin tube having an auxiliary heater for thermal fusion of the inner tube.

전기 및 통신선로 시설을 위한 다수의 내관이 구비된 합성수지관은 지반변동이나 관내의 압력변화에 적절히 신축작용을 이루게 하는 주름형이 주로 많이 이용되고 있는 것으로, 그러한 주름형의 합성수지관은 통상 압출 성형방식을 이용해 제조되고 있다.Synthetic resin pipes equipped with many inner pipes for electric and communication line facilities are mainly used in the form of pleats that allow them to be properly stretched and responded to ground fluctuations or pressure changes in the pipes. It is manufactured using the method.

이렇게 다수의 내관을 갖는 주름형의 합성수지관은 대략 내ㆍ외관 이중관, 즉 주름형으로 이루는 외관 내에 그 외관 보다 적은 크기의 적어도 하나 이상의 내관들을 내장하고, 그 내관들 각기에는 다종의 광케이블들이 각기 분리 설치되어 목적하는 다중 통신선로를 시설시키고 있는 것이다.Thus, a corrugated synthetic resin tube having a plurality of inner tubes has at least one inner tube having a size smaller than that of the inner and outer double tubes, that is, a corrugated exterior, and each of the inner tubes has a plurality of optical cables separated from each other. It is installed to install the desired multiple communication line.

그런데 이와 같이 다수의 내관들이 내장되는 합성수지관에서 내관들은 외관 내에 자유한 상태로 삽입되고 있는데, 이때 자유한 상태의 내관들은 외관 내에서 자유로이 유동되고 있어 그 내관들이 외관내에서 정렬되지 못하고 비틀림이 일어나 시공작업에 많은 불편을 주고 있다.However, in the synthetic resin tube in which a plurality of inner tubes are embedded, the inner tubes are inserted freely in the exterior. In this case, the inner tubes are freely flowing in the exterior, and the inner tubes are not aligned in the exterior and there is a torsion. The construction work is giving a lot of inconvenience.

또 다수의 내관들이 내장되는 합성수지관의 운반은 대략 두루마리식으로 감아 운반시키고 있는데, 상기에서와 같이 외관 내에서 자유한 상태로 내장되어 있던 내관이 감겨진 합성수지관의 펼침 시 그 펼침 탄력에 의해 외관 내에서 외부로 이탈하는 현상이 일어나 치명적인 안전사고가 발생하고 있는 것이다.In addition, the conveyance of the synthetic resin tube in which a plurality of inner tubes are built is wound and transported in a roughly rolled manner. As shown above, the inner tube that is built freely in the outer appearance is wound by the unfolding elasticity when the inner tube is unfolded. A phenomenon that deviates from inside to outside occurs, causing a fatal safety accident.

이러한 합성수지관 외관 내에서의 내관들 비틀림이나 이탈현상은 시설 작업에 많은 불편을 주어 작업성과 제품성을 낮추는 주 요인이 되고 있는 것이다.Twisting or deviating phenomena of the inner pipes in the exterior of the synthetic resin pipe are a major factor in reducing workability and productability due to a lot of inconvenience in facility work.

그리하여 근래에 와서는 상기에서와 같은 문제점을 해결하기 위해 합성수지관의 외관 내에서 내관들의 유동을 방지시키기 위해 외관의 내벽에 내관들이 정착되는 구조의 혁신이 요구되어 이건 출원인이 상기에서의 과제를 해결하는 특허(10-773083호)를 받은 바 있는데, 이 특허 제품의 제조장치가 요구되고 있는 실정이다. Thus, in recent years, in order to solve the problems as described above, the innovation of the structure that the inner tubes are fixed to the inner wall of the exterior to prevent the flow of the inner tubes in the exterior of the synthetic resin tube is required, which solves the above problems. Has received a patent (No. 10-773083), the situation is required to manufacture a device for this patent product.

The apparatus for manufacturing a synthetic resin pipe according to the present invention uses a first extruder to directly contact the exterior using an auxiliary heater, which consists of direct and indirect heating sources of the inner pipes immediately before the inlet of the second extruder into which the pre-extruded inner pipes are introduced. It is obtained by melting more effectively and locally, the inner tube is stable and firmly fixed in the appearance and prevents safety accidents as well as product quality.
