상기와 같이 제조된 패드는 단면 형상을 가지며 이를 통해 농업용으로는 비닐하우스의 조립 시 비닐을 고정할 수 있는 패드로서 사용할 수 있게 되며, 건축용으로는 건축물 천정받침 경량철골로 사용하게 된다.The pads manufactured as described above have a cross-sectional shape and can be used as pads for fixing vinyl during assembly of a plastic greenhouse for agricultural use, and as a lightweight steel frame for a ceiling mount for a building.

언코일러(uncoiler)는 일정한 폭의 강판을 코일 형태로 감고 있는 원재를 장착하여 이를 연속적으로 공급하기 위한 장치로서, 상기 강판은 이후 제조공정을 수행하기 위한 각 장치와 연결되어 있으며, 강판이 이송되면서 제품 형태로 가공되고 도장 및 절단되어 최종적인 색상패드 제품의 완성까지 이어져 수행된다.An uncoiler is a device for continuously supplying a raw material with a coil of a certain width rolled in the form of a coil, which is connected to each device for carrying out a manufacturing process thereafter, Processed into a product form, painted and cut to the finish of the final color pad product.

상기 언코일러에서 풀려나온 강판은 전기로로 이송되어 1차 예열처리되는데, 이때, 상기 언코일러와 전기로 사이에 센서를 장착하여 강판의 이송 여부를 감지하도록 할 수 있다. 상기 센서는 상기 언코일러의 전원과 연결되어 있고, 상기 강판이 이송 중 외부의 영향으로 중지되거나 강판이 절단되는 등 강판의 이송이 감지되지 않으면, 상기 센서의 신호에 의해 언코일러의 전원이 차단되어 공정을 중지할 수 있다. 또한, 상기 언코일러에 장착된 강판이 모두 소진되었을 경우 상기 센서는 전기로, 압연 롤러, 포밍장치, 도장장치 등의 모든 장치의 전원과 연결됨으로써 언코일러의 동작 정지와 함께 모든 작업을 중지하도록 할 수 있다.The steel sheet unwound from the uncoiler is conveyed to an electric furnace to be subjected to primary preheating treatment. At this time, a sensor may be installed between the uncoiler and the electric furnace to detect whether the steel sheet is conveyed. The sensor is connected to the power source of the uncoiler. If the steel sheet is not detected due to the influence of the outside during the conveyance or the steel sheet is cut, the power of the uncoiler is cut off by the signal of the sensor The process can be stopped. In addition, when all of the steel plates mounted on the uncoiler are exhausted, the sensor is connected to the power sources of all the devices such as the electric furnace, the rolling roller, the forming device, and the coating device so as to stop the operation of the uncoiler .

상기 1차 예열단계는 상기 강판을 전기로 내로 통과시키면서 강판의 표면에 묻은 기름때나 불순물을 연소하여 제거하기 위한 것으로 500 내지 550℃의 온도에서 처리하는 것이 바람직하다.The primary preheating step is preferably carried out at a temperature of 500 to 550 DEG C to burn and remove oil mist or impurities adhering to the surface of the steel sheet while passing the steel sheet through an electric furnace.

상기 전기로를 통과한 강판은 표면의 불순물이 연소되면서 그을음 등이 발생하게 된다. 따라서 강판이 이송되면서 약품처리를 하여 상기 표면의 그을음 등을 제거하게 된다. 이송된 강판의 표면에 세척제를 분사한 후 브러쉬를 통과시키면 브러쉬가 상기 강판의 표면을 닦아 세척제 성분과 함께 표면의 그을음을 제거할 수 있다. 이때 상기 브러쉬는 상기 강판의 상하를 모두 닦을 수 있도록 2개가 인접하여 설치되는 것이 바람직하다.The steel sheet passing through the electric furnace is burned with impurities on the surface, and soot or the like is generated. Thus, the steel sheet is transferred while being subjected to chemical treatment to remove soot and the like on the surface. When the cleaning agent is sprayed on the surface of the transferred steel sheet and then passed through the brush, the brush can wipe the surface of the steel sheet to remove the soot on the surface together with the cleaning agent component. At this time, it is preferable that two brushes are provided adjacent to each other so as to wipe both the upper and lower portions of the steel sheet.

다음으로 상기 브러쉬를 통과한 강판의 표면에 잔존하는 세척제를 제거하기 위하여 상기 강판의 표면을 세척하는 수세단계를 거치게 된다. 상기 수세단계에서는 상기 강판의 상하로 동시에 물을 분사하여 세척을 수행한다. 이후 상기 수세된 강판의 표면을 다시 브러쉬 사이로 통과시키면서 2차 브러쉬 처리단계를 거치고, 수분이 남은 상기 강판을 건조기 내로 이송하여 수분을 제거하게 된다. 상기 건조기는 150 내지 200℃의 온도를 유지하도록 하여 상기 강판이 통과되면서 수분이 모두 제거되도록 하는 것이 바람직하다.Next, in order to remove the cleaning agent remaining on the surface of the steel sheet passed through the brush, the surface of the steel sheet is washed. In the washing step, water is simultaneously sprayed on the upper and lower sides of the steel sheet to perform cleaning. Thereafter, the surface of the washed steel sheet is passed through the brush again, subjected to a secondary brush treatment step, and the steel sheet having moisture remaining therein is transferred into the dryer to remove moisture. Preferably, the dryer is maintained at a temperature of 150 to 200 ° C. so that the steel sheet is completely removed from the steel sheet.

상기와 같이 전처리를 거친 강판을 압연 롤러 사이로 통과시키는데, 압연 롤러의 요철 패턴에 의하여 상기 강판의 표면에 도 2에서와 같은 체크무늬가 형성되게 된다. 이러한 체크무늬가 표면에 형성되면 강판을 포밍할 때 강도를 향상시킬 수 있어 강판이 손상되는 것을 막을 수 있다. 또한, 압연 과정을 거침으로써 강판에 탄성이 부여되어 내구성이 향상되게 된다.The pre-treated steel sheet passes through the rolling rollers as described above, and a checkered pattern as shown in FIG. 2 is formed on the surface of the steel sheet by the concavo-convex pattern of the rolling roller. When such a checkered pattern is formed on the surface, the strength can be improved when the steel sheet is formed, and damage to the steel sheet can be prevented. Further, by passing through the rolling process, elasticity is imparted to the steel sheet, and durability is improved.

상기 압연 롤러는 3단계로 이루어 질 수 있는데, 1단계는 1㎜ 두께의 강판을 처리하는 것이고, 2단계는 1㎜ 두께의 강판을 0.8㎜로 조절하는 것이며, 3단계는 0.8㎜ 두께의 강판을 0.7㎜로 조절하는 것이다. 즉, 사용자의 두께 요구에 따라 압연 롤러의 압력을 변형시킴으로써 맞춤형 색상패드를 제조할 수 있게 된다. 만일, 사용자가 1㎜ 두께의 강판을 요구하면 2단계와 3단계는 거치지 않고 통과시키면 된다.The rolling roller can be made in three steps. The first step is to process a steel sheet having a thickness of 1 mm. The second step is to adjust a steel sheet having a thickness of 1 mm to 0.8 mm. 0.7 mm. That is, it is possible to manufacture a customized color pad by deforming the pressure of the rolling roller according to the thickness demand of the user. If the user requests a steel sheet having a thickness of 1 mm, it is sufficient to pass the steel sheet without passing through steps 2 and 3.

상기 압연 롤러로 처리된 강판은 포밍장치를 통과하게 되는데, 상기 포밍장치는 16개의 포밍기가 연속하여 배치되어 있어 강판이 서서히 굴곡(성형)되어 제품 형상을 이루게 된다. 포밍기의 개수가 많아질수록 강판의 미세 가공이 가능하나 공정비용이 증가하므로 16개 이상의 포밍기를 설치하는 것은 바람직하지 않고, 포밍기의 개수가 너무 적으면 강판이 굴곡(성형) 가공되는 속도가 너무 빨라 부분적인 형상 변형 등의 불량이 발생할 우려가 있다.The steel plate treated with the rolling roller passes through a forming device, in which 16 forming devices are successively arranged, so that the steel plate is gradually bent (formed) to form a product shape. It is not desirable to install more than 16 formers, and if the number of forming machines is too small, the speed at which the steel sheet is bent (formed) It is too fast to cause defects such as partial shape deformation.

상기 포밍장치를 통과하면서 제품이 제조되게 되는데, 상기 제품은 전기로를 통과하면서 2차 예열단계를 거치게 된다. 상기 2차 예열단계에서도 전기로는 500 내지 550℃의 온도를 유지하는 것이 바람직한데, 상기 2차 예열단계를 거치는 이유는 성형된 제품의 형상을 안정화시키기 위함이다. 즉, 표면 열처리를 통해 이후 설명될 도장단계에서 색상도료의 도포 속도와 도포 균일성이 향상되게 된다. 상기 2차 예열단계를 거치지 않고 바로 도장공정을 수행하는 경우 도장의 두께 균일성이나 굴곡진 부분의 도장 균일성이 저하되는 문제점이 있으므로 반드시 상기 2차 예열단계를 거쳐야 한다.The product is manufactured while passing through the forming device. The product passes through the electric furnace and undergoes a second preheating step. In the second preheating step, it is preferable that the electric furnace maintains a temperature of 500 to 550 ° C. The reason for passing through the second preheating step is to stabilize the shape of the molded product. That is, through the surface heat treatment, the coating speed and the coating uniformity of the color paint are improved in the coating step to be described later. If the coating process is carried out directly without the second preheating step, there is a problem that the thickness uniformity of the coating or the coating uniformity of the curved portion is lowered. Therefore, the second preheating step must be performed.

상기 2차 예열된 제품은 도장장치 내로 이송된다. 도장장치의 내부는 도 3에서 도시된 바와 같은데, 제품이 통과하면서 전체적으로 균일하게 도장이 되어 나오게 된다. 상기 도장장치는 2단계로 이루어 질 수 있는데, 1단계는 하부에 설치된 딥핑부스를 통과하는 것이고, 2단계는 상부에 설치된 다수개의 스프레이 건으로 분무하는 것으로 구성되어 있다. 이에 따라 제품이 통과할 때 제품의 전 측면에서 색상도료를 도포하여 도장하게 되므로 빠른 시간에 균일한 도장이 가능하게 된다.The second preheated product is transferred into the coating apparatus. The inside of the painting apparatus is as shown in FIG. 3, and the product is uniformly coated as a whole through the passage. The coating apparatus may be composed of two stages, that is, one stage passes through a dipping booth installed in the lower stage, and the second stage consists of spraying a plurality of spray guns installed on the upper stage. Accordingly, when the product is passed through, the color paint is applied on the entire surface of the product, so that uniform coating can be performed in a short time.

상기 하부의 딥핑(dipping)과 상부의 스프레이(spray)를 2단계로 거치는 이유는, 상기 하부의 딥핑만 실시할 경우에는 굴곡(성형)된 부분에 도포액이 모여진 채로 응고되며, 상기 상부의 스프레이만 실시할 경우에는 반대로 굴곡(성형)된 부분에는 도포액이 도장되기 어렵기 때문이다. 상기 스프레이는 대각선 방향으로 굴곡(성형)된 부분에 분무되도록 함은 자명하다. 즉, 굴곡(성형)되어 이송되는 강판의 하부와 상부에 딥핑과 스프레이가 순차적으로 이루어지게 함으로써 완벽한 도장을 이룰 수 있는 것이다. The reason why the lower dipping and the upper spray are performed in two stages is that when the lower dipping is performed only, the coating liquid is solidified on the bent (molded) part, and the upper spray It is difficult for the coating liquid to be applied to the bent portion. It is obvious that the spray is sprayed on the bent (molded) part in the diagonal direction. That is, dipping and spraying are sequentially performed on the lower part and the upper part of the steel sheet to be bent (molded), thereby achieving a perfect coating.

도장단계를 거친 제품은 즉시 적외선 장치 내로 이송되는데, 상기 적외선 장치에서는 100 내지 110℃의 열을 발생시켜 색상도료를 신속하게 건조할 수 있게 된다. 상기 적외선 장치에서는 적외선 발생기가 상부에 설치되어 상부에서 하부로 적외선을 조사하게 되므로, 제품의 굴곡진 내부에 적외선이 많이 조사되어 건조 효율이 향상되게 된다. The product that has undergone the painting step is immediately transferred into the infrared ray apparatus. In the infrared ray apparatus, the color paint can be rapidly dried by generating heat of 100 to 110 ° C. In the infrared ray apparatus, since the infrared ray generator is installed on the upper part and irradiates the infrared rays from the upper part to the lower part, a large amount of infrared rays are radiated into the curved inner part of the product, thereby improving the drying efficiency.

이후, 상기 건조된 제품을 냉각기 내로 이송하여 냉각하고 리미트 절단기를 사용하여 상기 냉각된 제품을 절단하여 제조하게 된다. 상기 리미트 절단기는 센서에 의해 구동되며 사용자가 요구하는 길이에 따라 절단하되 통상적으로 6m 간격으로 색상패드를 절단하도록 작동한다.Thereafter, the dried product is transferred into a cooler, cooled, and cut by using a limit cutter to produce the cooled product. The limit cutter is driven by a sensor and is operated to cut the color pad at a distance of typically 6m, according to the length required by the user.

상기 강판 공급단계부터 절단하여 색상패드를 제조하는 모든 공정은 하나의 연속된 작업으로 이루어지도록 한다. 즉 단일 공정을 실시함으로써 생산의 효율성을 극대화시키는 것을 본 발명의 주요 특징으로 한다.All the steps of cutting the steel sheet from the steel sheet supplying step to produce the color pads are performed in a single continuous operation. That is, the main feature of the present invention is to maximize the efficiency of production by performing a single process.

또한, 상기 절단되어 얻어진 색상패드는 각 패드를 연결하여 사용하여야 하는데, 종래에는 체결부재를 통해 결합시키거나 내부끼움부와 외부끼움부가 형성된 연결클립을 따로 제조하여 각 패드를 연결할 수 있도록 하고 있다. In addition, the color pads obtained by cutting should be used by connecting the respective pads. Conventionally, connection pads are formed by joining the pads through a fastening member, or by forming a connection clip in which an internal fitting portion and an external fitting portion are formed.

그러나, 본 발명에서는 이러한 별도의 체결부재 없이도 색상패드 간의 결합이 이루어질 수 있도록 도 4와 같이 색상패드의 일측을 확관시켜 폭이 넓어지게 하고 다른 색상패드를 끼움을 통해 각각의 칼라패드를 연결할 수 있어 현장에서 작업 속도를 크게 향상시킬 수 있으며, 체결부재나 연결클립 등을 이용할 필요가 없게 된다.However, according to the present invention, one side of the color pad can be enlarged as shown in FIG. 4 so that the color pads can be coupled without any separate fastening member, and the respective color pads can be connected through the other color pads It is possible to greatly improve the working speed in the field, and it becomes unnecessary to use the fastening member, the connection clip, or the like.

본 발명은 상술한 바와 같이 설명하였으나, 상기 설명에 한정되지 아니하며 본 발명의 정신을 벗어나지 않는 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 다양한 변형과 변경이 가능하다. 그러한 변형 및 변경은 본 발명과 첨부된 특허청구범위의 범위 내에 속하는 것으로 보아야 한다.While the present invention has been described in detail, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Such variations and modifications are to be considered as falling within the scope of the invention and the appended claims.
