Description

분체도장시스템{powder coating system}Powder coating system

본 발명은 분체도장시스템에 관한 것으로서, 보다 상세하게는 색상교체시 발생되는 라인중지시간을 단축시켜, 생산성을 향상시킬 수 있도록 된 새로운 개념의 분체도장시스템에 관한 것이다.The present invention relates to a powder coating system, and more particularly, to a powder coating system of a new concept that can shorten the line stop time generated during color replacement and improve productivity.

일반적으로, 금속의 표면을 도색할 때 주로 사용되는 분체도장은 분말상태로 이루어진 분체도료를 고전압하에서 (-)또는 (+)전기로 대전시켜 피도장물의 표면에 분사하여, 분체도료를 피도장물에 전기적으로 부착한 후, 도료를 가열, 용해 및 경화하여 도장하는 것으로, 상기 피도장물은 컨베이어와 같은 이송장치를 이용하여 자동으로 공급되는 것이 일반적이다. 이러한 분체도장은 용제를 사용하지 않으므로, 용제에 의한 중독이나 화재의 위험이 없으며, 공해를 발생시키지 않을 뿐 아니라, 액체도료를 사용할 때 발생되는 주름현상이나 흐름현상이 없고, 내구성이 우수한 도막을 형성할 수 있는 장점이 있다.In general, powder coating, which is mainly used to paint the surface of the metal, is applied to the surface of the coating by charging the powder coating made of powder state with (-) or (+) electricity under high voltage, and spraying the powder coating After electrically adhering to the coating, the paint is heated, dissolved, and cured to be painted, and the coating is generally supplied automatically using a conveying device such as a conveyor. Since the powder coating does not use a solvent, there is no danger of poisoning or fire caused by the solvent, it does not cause pollution, and there is no wrinkle or flow phenomenon generated when using liquid paint, and it forms an excellent coating film. There is an advantage to this.

그런데, 이러한 분체도장은 분말상태의 도료를 피도장물에 분사하므로, 도료가 공기중에 확산되어 분진이 많이 발생된다. 따라서, 피도장물을 이송하는 이송장치의 중간부에, 외부와 격리된 도장부스를 설치하고, 이 도장부스의 내부에서 도장작업을 하여야 한다.By the way, such powder coating sprays the powder coating material onto the coating material, so that the coating material is diffused in the air and a lot of dust is generated. Therefore, a painting booth isolated from the outside is to be provided in the middle of the conveying apparatus for transferring the workpiece, and the painting work must be performed inside the painting booth.

한편, 이와같은 분체도장은 많은 양의 분체도료를 피도장물의 표면에 분사하고, 피도장물의 표면에 부착되지 않은 여분의 분체도료는 다시 회수하여 재사용하게 되는데, 이과정에서 분체도료의 일부가 도장부스 내부를 오염시키게 된다. 따라서, 도장하고자 하는 색이 바뀔 경우, 다른 색의 분체도료가 서로 섞이지 않도록 하기 위해, 도장부스 내부를 청소하여, 도장부스 내부에 남아있는 분체도료를 모두 제거한 후, 다른 색깔로 도장을 하여야 한다.On the other hand, such a powder coating is sprayed a large amount of powder coating on the surface of the coating, and the excess powder coating that is not attached to the surface of the coating is recovered and reused, during which part of the powder coating is painted The inside of the booth will be contaminated. Therefore, when the color to be painted is changed, in order to prevent the powder coatings of different colors from mixing with each other, the inside of the coating booth should be cleaned, all the powder coating remaining in the coating booth should be removed, and then the coating should be performed in a different color.

그러나, 이와같이, 도장부스의 내부를 청소하기 위해서는 비교적 오랜 시간이 소요되며, 이와같이, 도장부스의 내부를 청소할 때는, 분체도장의 다른 공정도 정지하여야 하므로, 생산성이 낮아지는 문제점이 있었다. 특히, 다른 업체에서 의뢰한 제품에 분체도장을 하는 분체도장 전문업체의 경우, 다양한 색을 이용하여 도장을 하여야 하므로, 도장부스의 내부를 청소함에 따른 시간손실이 매우 많은 문제점이 있었다.However, as described above, it takes a relatively long time to clean the interior of the coating booth, and thus, when cleaning the interior of the coating booth, other processes of powder coating must also be stopped, resulting in low productivity. In particular, in the case of powder coating specialists that apply powder coating to products requested by other companies, the coating must be done using various colors, and thus, there is a problem of time loss due to cleaning the inside of the coating booth.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 색상교체시 발생되는 라인중지시간을 단축시켜, 생산성을 향상시킬 수 있도록 된 새로운 개념의 분체도장시스템을 제공하는 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a powder coating system of a new concept to shorten the line stop time generated during color replacement, thereby improving productivity.
