Description

강관 도장장치 {Coating device of a steel pipe}  Coating device of a steel pipe}

본 발명은 강관 도장장치에 관한 것으로, 더욱 구체적으로는 강관의 외면을 분체식으로 피복하기 위하여 강관 인양이 가능하고 강관 내면을 차단할 수 있도록 하는 고정커버판을 강관의 직경 크기에 관계없이 강관의 양단부에 밀착고정할 수 있게 하고, 강관의 하부에서 상향 분사되어 3중 피복이 이루어지도록 도료분사탱크를 분할 구획시켜 도료분사 및 피복되지 않은 도료의 회수가 이루어지도록 한 도료분사부의 상단 입구를 강관 외경 크기에 따라 가변되게 하여 도료의 분리회수가 용이하도록 한 강관 도장장치에 관한 것이다.
The present invention relates to a steel pipe coating device, and more specifically, to cover the outer surface of the steel pipe in a powder form, both ends of the steel pipe can be fixed to the steel pipe irrespective of the diameter size of the steel pipe, which is capable of lifting the steel pipe and blocking the inner surface of the steel pipe. To the upper part of the paint spraying part to divide the paint spraying tank into a three-layer coating by spraying upward from the lower part of the steel pipe, and to recover the paint spraying and the uncoated paint. The present invention relates to a steel pipe coating device that is made variable according to and facilitates separation recovery of paint.

일반적인 강관의 도장수단은 강관에 쇼트 블라스트(Shot Blast)와 같은 전처리 공정을 통해 이물질을 제거하고, 소정의 온도로 강관에 열을 가한 뒤, 분말형태의 피복재를 녹여서 일체시키는 분말용착식 도장법과 가열된 강관 외면에 점착제를 도포하고 압출장치를 통해 피복재를 입히는 압출성형식 도장법이 있다.In general, the painting means of steel pipe is powder welded coating method and heating to remove foreign substances through pretreatment process such as shot blast on steel pipe, heat the steel pipe to a predetermined temperature, and melt by coating powder type coating material. There is an extruded coating method in which a pressure-sensitive adhesive is applied to the outer surface of a steel pipe and a coating material is coated through an extrusion device.

이와 같은 도장방법 중 압출성형식은 분말용착식에 비해 강관에 대한 피복의 중첩성형이 가능하므로 부식에 대한 저항성을 제고함으로써, 강관의 내구성 향상을 도모하는 등 뛰어난 효과가 발휘된다. 그러나 동일한 치수의 강관에 대한 피복작업 이외에 강관의 직경이 일률적이지 못한 경우, 생산성이 떨어지는 문제점이 있고, 대형 강관에 대한 공정 설비상의 한계를 안고 있는 문제점이 있다.Among the coating methods, the extruded type is capable of overlapping the coating of the steel pipes compared to the powder welding type, thereby enhancing the resistance to corrosion, thereby improving the durability of the steel pipes, and exhibiting excellent effects. However, if the diameter of the steel pipe is not uniform in addition to the coating work for the steel pipe of the same dimension, there is a problem that the productivity is low, and there is a problem in the limitation of the process equipment for large steel pipe.

이를 감안하여 분말형태의 에폭시와 피복재 즉, 강관에 용착되었을 때, 접착성 도포층을 형성하는 에폭시 및 개질 폴리에틸렌 분말과 표층 피복을 형성하는 폴리에틸렌 분말을 이용하여 강관의 피복을 중첩시키는 일종의 분말용착식 도장방법에 의해 강관의 외면을 피복하는데 많이 사용되고 있다.In view of this, a type of powder welding type that overlaps the coating of steel pipes by using epoxy in powder form and a coating material, that is, epoxy and modified polyethylene powder to form an adhesive coating layer and polyethylene powder to form a surface coating when welded to a steel pipe. It is widely used to coat the outer surface of steel pipe by the coating method.

이러한 분말 용착식 도장방법에서는 강관의 외면을 분체식으로 피복하기 위하여 강관 인양이 가능하고 강관 내면을 차단할 수 있도록 강관공급장치의 구동샤프트에 연결된 고정커버판을 강관의 양단부를 밀착고정한 다음 상기 강관공급장치의 구동샤프트에 의해 강관을 회동시키면서 강관 외면에 분말도료를 분사하여 피막이 형성되도록 한 도장장치가 사용되고 있으나, 종래에는 고정커버판의 둘레에 결합단턱이 일체로 형성되어 그 결합단턱을 강관 내면에 밀착되게 나사 결합하거나 볼트 등의 체결하여 밀착고정하는 구성이므로 강관의 직경 크기가 다른 것을 분체 도장하기 위해서는 강관 내부 직경 크기별로 고정커버판을 각각 구비하여야 할 뿐 만 아니라 고정커버판의 교체 및 설치가 번거롭기 때문에 작업생산성이 크게 떨어지고 구입비용도 많이 들게 되었다.
In this powder welding coating method, to cover the outer surface of the steel pipe by powder type, it is possible to lift the steel pipe and fix the fixed cover plate connected to the driving shaft of the steel pipe supplying device so as to block the inner surface of the steel pipe in close contact with both ends of the steel pipe, and then supply the steel pipe. A coating device is used in which a coating is formed by spraying powder coating on the outer surface of the steel pipe while rotating the steel pipe by the drive shaft of the device. However, in the related art, a coupling step is integrally formed around the fixed cover plate, and the coupling step is formed on the inner surface of the steel pipe. Since it is a structure that is screwed tightly or fastened tightly by fastening bolts, etc., in order to powder coating different diameter pipe diameters, not only the fixed cover plates should be provided for each inner diameter of the steel pipe, but also the replacement and installation of the fixed cover plate is necessary. As it is cumbersome, work productivity is greatly reduced and purchase cost It cost a lot.

한편, 강관의 외면을 에폭시 접착층, 폴리에틸렌 접착층, 폴리에틸렌 수지층으로 이루어진 3층의 피복층을 이루도록 하고 있는바, 이는 강관을 장착한 상태에서 회전구동이 이루어지고 대차의 상부에 안착되는 한 쌍의 강관설치부, 그리고 에폭시분말과 접착성 개질 폴리에틸렌 및 표층용 폴리에틸렌으로 소정의 도장층을 형성하기 위한 3개의 도장장치가 각각 구비되어 있다.On the other hand, the outer surface of the steel pipe to form a three-layer coating layer consisting of an epoxy adhesive layer, a polyethylene adhesive layer, a polyethylene resin layer, which is a pair of steel pipe installation is carried out in the state in which the steel pipe is mounted and seated on the top of the bogie In addition, three coating apparatuses for forming a predetermined coating layer with epoxy powder, adhesive modified polyethylene and surface layer polyethylene are provided.

이와 같은 종래의 분말 용착식 도장 방법의 경우, 도장원료를 스프레이를 통해 도포하게 되는 것으로, 강관과 노즐 간의 거리조절이 어려우므로 인해 도장이 누락되거나 도포되는 두께가 일정하게 유지되지 않는 등 품질상의 문제점이 유발된다.In the conventional powder weldable coating method, the coating material is applied by spraying, and the distance between the steel pipe and the nozzle is difficult to adjust, so that the coating is missing or the thickness of the coating is not kept constant. This is caused.

상기와 같은 문제를 해결하기 위한 3층 피복 강관의 분말 용착식 도장장치 등이 개시되어 있으며, 그 구성은 주로 강관으로 도장 원료를 분사하는 분사 장치와, 상기 강관의 단부 양측에 장착되는 고정 장치와, 상기 강관의 단부에 장착된 고정 장치가 안착된 후 각각 회전시키는 회전 장치와, 상기 회전 장치를 이동하는 대차로 구성되어 있다.A powder weldable coating apparatus for a three-layer coated steel pipe for solving the above problems is disclosed, and the configuration is mainly a spraying device for injecting the coating raw material into the steel pipe, and a fixing device mounted to both ends of the steel pipe; And a rotating device for rotating the fixed device mounted on the end of the steel pipe, respectively, and a bogie for moving the rotating device.

그러나 상기의 강관 외면에 분말식으로 도장하는 종래기술은 분사장치가 상하 이동 및 수평이동되게 한 구성이므로 경제적인 부담이 크고, 강관과 노즐 간의 거리조절이 어려우므로 인해 도장이 누락되거나 도포되는 두께가 일정하게 유지되지 않는 등 품질상의 문제점과, 강관설치부에 의해 회전하는 강관의 상부에서 도장원료인 접착성 개질 폴리에틸렌이나 표층용 폴리에틸렌 분말을 자유 낙하시키는 도장을 하는 경우에 도장 원료인 분말의 밀도가 1.0보다 적고, 입자의 크기 또한 미세하므로 이를 자유 낙하시키면, 미세한 바람이나 고온으로 가열된 강관의 외면으로부터 발산되는 상승기류 등에 의해 분말이 비산되는 문제점이 있다. 이것은 결국 강관의 외면에 접착성 개질 폴리에틸렌 및 표층용 폴리에틸렌의 일정한 도포를 저해함으로 강관의 도장 품질을 저하시키는 문제점이 있다.
However, the prior art of painting the outer surface of the steel pipe in powder form is a configuration in which the injector is moved up and down and horizontally moved, so the economic burden is large, and because the distance between the steel pipe and the nozzle is difficult to adjust, the thickness of the coating is missing or applied. In the case of quality problems such as not being kept constant, and in the case of coating to freely drop adhesive modified polyethylene or surface layer polyethylene powder, which is a coating material, on the upper part of the steel pipe rotated by the steel pipe installation part, Less than 1.0, the size of the particles is also fine, so if the free fall, there is a problem that the powder is scattered by the fine wind or the air flow emitted from the outer surface of the steel pipe heated to a high temperature. This in turn has a problem of lowering the coating quality of the steel pipe by inhibiting the uniform application of the adhesive modified polyethylene and the surface layer polyethylene on the outer surface of the steel pipe.

본 발명은 이러한 문제점을 해결하기 위하여 안출한 것으로, 강관공급장치의 구동샤프트에 연결되어 강관의 양단부에 밀착고정하기 위한 고정커버판에 강관 내부 직경 크기에 따른 가변 조절하여 고정할 수 있는 체결부재를 구비하여 고정커버판을 강관의 직경 크기에 관계없이 강관의 양단부에 밀착고정할 수 있는 범용성을 갖도록 함과 아울러 강관의 하부에서 상향 분사되어 3중 피복이 이루어지도록 도료분사탱크를 분할 구획시킨 각 도료분사부의 상단 입구를 강관 외부 직경 크기에 따라 가변하여 근접상태로 차단할 수 있도록 하여 도료의 분리회수가 이루어지도록 한 강관 도장장치를 제공함에 있다.
The present invention has been made in order to solve this problem, the fastening member that can be connected to the drive shaft of the steel pipe supply device to the variable cover according to the size of the inner diameter of the steel pipe fixed to the fixed cover plate for tightly fixed to both ends of the steel pipe Each coating is divided into paint spray tanks so that the fixed cover plate can be fixed to both ends of the steel pipe irrespective of the size of the steel pipe and is sprayed upward from the bottom of the steel pipe to form a triple coating. According to the present invention, there is provided a steel pipe coating device which allows a separate recovery of paint to be made by varying the top inlet of the injection unit according to the size of the outer diameter of the steel pipe.
