Description

복합저장탱크용의 원통과 경판(梗板)의 자동용접장치{Automatic Welding Installation of a Cylinder and Closing Plate for a Storage Tank}Automatic Welding Installation of a Cylinder and Closing Plate for a Storage Tank

본 발명은 대ㆍ소형 원통형의 플라스틱 복합저장탱크용의 원통에 경판(梗板)을 용접하기 위한 복합 저장탱크용 원통과 경판의 용접장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a welding device for a cylindrical storage tank and a welding plate for welding a light plate to a cylinder for a large and small cylindrical plastic compound storage tank.

일반적으로 원통형 플라스틱 탱크용 원통의 양단에 그것을 막아주는 경판(梗板)을 용접하는 방법으로는 맞대기 용접(Butt welding)이나 필렛 용접(Fillet welding)등의 방법이 있고 그 중 일반화 된 방법인 필렛 용접의 경우에는 경판을 원통에 맞대고 그 맞닿는 용접부위에 열을 가하여 예열함과 동시에 그 플라스틱 원통 및 경판과 동일재질의 합성수지(예컨데 폴리에틸렌 합성수지)를 용융한 것을 공급하면서 용접하고 있으나 이 경우 용접을 소형 용접장치를 사용하여 수동으로 용접 하게되므로 작업시간이 많이 소요되고 작업자가 숙련되지 않은 경우 용접부위가 균일하지 못하고 경판 및 원통이 맞닿는 부위의 용융정도가 일정치 못하여 용접이 잘되지 않거나 균일 용접이 어렵고 용접을 위해 거기에 공급되는 동일재질의 합성수지도 일정양으로 균일하게 충분한 양을 공급하기가 어려워서 용접부위가 균일하지 못한 결점이 있게되며, 또한 수공에 의해서는 용접부위의 예열과 동일재질의 용융 합성수지의 공급및 용접 부위의 고르기등의 작업을 동시에 하기란 매우 어려운 단점이 있었다.In general, there is a method of welding a hard plate that prevents it from both ends of a cylinder for a cylindrical plastic tank, such as butt welding or fillet welding, the most common method of which is fillet welding In this case, the hard plate is welded to the cylinder by applying heat to the abutting welds and supplying molten synthetic resin (e.g. polyethylene synthetic resin) of the same material as the plastic cylinder and hard plate. Because welding is done manually by using, it takes a lot of work time and if the worker is not skilled, the welding part is not uniform and the degree of melting of the area where the hard plate and the cylinder abuts is not constant, so that the welding is not good or uniform welding is difficult and the welding is difficult. The synthetic resin of the same material supplied there for uniformly It is difficult to supply a sufficient amount, so there is a defect that the welding part is not uniform, and it is very difficult to carry out the work of preheating the welding part, supplying molten synthetic resin of the same material, and selecting the welding part at the same time by hand. There was this.

본 발명은 상기한 바와같은 종래의 원통형 플라스틱 복합저장탱크용의 원통에 경판을 용접함에 있어서의 결점을 개선하여 용접코저하는 부위를 예열함과 동시에 그 부위에 동일 재질의 용융된 용접재료를 균일하게 공급하면서 용접한 후 그 용접부위를 롤러로 균일하게 골라주는 작업을 자동장치에 의해 일괄적으로 동시에 행할 수 있는 원통형 플라스틱 복합저장탱크용의 원통과 경판의 자동용접장치를 제공코저하는 것으로서 이를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.The present invention improves the defects in welding a hard plate to a cylindrical cylinder for a conventional cylindrical plastic composite storage tank as described above, while preheating the welded portion and uniformly melting molten welding material of the same material thereon. It is to provide automatic welding device for cylinder and hard plate for cylindrical plastic compound storage tank which can carry out the work of welding and supplying the welding part uniformly and uniformly by roller automatically. When described in detail with reference to the accompanying drawings as follows.

Close the crater 11 and then preheat the welded portion of the tank cylinder 17 and the welded portion of the hard plate by injecting hot air through the crater 11 with the operation of the preheater 10 of the welding device body 21 first. At the same time, while heating the band heater 9 connected to the power source 15, the band heater 9 is continuously heated while administering the synthetic resin to be used for welding through the hopper 7, that is, synthetic resin of the same material as the cylinder and the hard plate. Synthetic resin administered in the heating extrusion device (8) At the same time as melting, the deceleration motor 6 is operated to rotate the extrusion screw in the heated extrusion apparatus 8 connected thereto so that the molten synthetic resin is extruded through the extrusion spray nozzle 18 and extruded through the nozzle 18.
