Description

그라비아 코팅 장치{Gravure coating device}Gravure coating device

본 발명은 그라비아 코팅 장치에 관한 것으로, 더욱 상세하게는 코팅하고자 하는 필터의 양면을 동시에 코팅 처리할 수 있는 한 쌍의 롤러가 구비된 그라비아 코팅 장치에 관한 것이다.The present invention relates to a gravure coating device, and more particularly, to a gravure coating device having a pair of rollers capable of simultaneously coating both surfaces of the filter to be coated.

일반적으로, 필름 상에 코팅액을 코팅하는 여러 장치 중에 그라비아 코팅 방법을 이용하는 장치가 안출되어 있는 실정이다.In general, a device using a gravure coating method has been devised among various devices for coating a coating liquid on a film.

그라비아 코팅 방법은 그라비아 롤을 코팅액에 침지시키고, 필름을 그라비아 롤과 접촉하면서 지나가게 하여, 그라비아 롤과 접촉되는 필름 면에 코팅액을 코팅하는 방법이다.The gravure coating method is a method of coating the coating solution on the film surface in contact with the gravure roll by immersing the gravure roll in the coating solution and passing the film in contact with the gravure roll.

그라비아 코팅방식은 다른 코팅방식에 비하여 코팅액의 손실이 적고 코팅이 고르게 이루어지는 장점이 있어 선호되고 있으며, 그라비아 코팅방식은 일반 그라비아 코팅방식(일반적으로 그라비아롤러의 직경이 100mm 이상인 것을 사용)과 마이크로 그라비아 코팅방식(그라비아롤러의 직경이 50mm 이하인 것을 사용)으로 구분된다.The gravure coating method is preferred because it has less loss of coating solution and uniform coating than other coating methods. The gravure coating method is a general gravure coating method (generally using a gravure roller having a diameter of 100mm or more) and microgravure coating. It is divided into a method (using a gravure roller whose diameter is 50 mm or less).

종래의 그라비아 코팅방식은 등록특허공보 제10-1257886호 '그라비아 코팅 장치'에서는 코팅을 하기 위한 필름의 피지 등을 제거하기 위한 에어블로잉(Airblowing) 후 이송 벨브에 실어 코팅액에 침지되어 있는 롤러가 필름의 하부를 코팅한 후, 사용자가 직접 필름의 상하를 반전시켜 다른 쪽 면을 코팅처리 함으로써, 필름의 양쪽면을 코팅하는 방식을 사용한다.Conventional gravure coating method is registered in Korean Patent No. 10-1257886 'Gravure coating device' is a roller that is immersed in the coating liquid loaded on the transfer valve after airblowing to remove the sebum of the film for coating, etc. After coating the lower part of the user, the user directly inverts the top and bottom of the film by coating the other side, thereby using a method of coating both sides of the film.

한편, 상기한 방식을 이용하여 필름을 코팅 시, 한쪽 면씩 코팅하므로 코팅액 소모량이 증가하고, 같은 작업을 2번 반복해야 하므로 작업시간이 많이 소모되는 문제점이 있었다.On the other hand, when coating the film using the method described above, because the coating liquid consumption is increased by one side, there was a problem that a lot of working time is consumed because the same operation must be repeated twice.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 코팅하고자 하는 필름의 양면을 동시에 코팅하여, 작업시간을 줄이고, 코팅액을 재사용하여 코팅액 소모량을 줄이는 그라비아 코팅 장치를 제공하는 것을 주요 목적으로 한다.The present invention has been made in order to solve the above problems, the main object of the present invention to provide a gravure coating device for coating the both sides of the film to be coated at the same time, reducing the work time, reducing the consumption of the coating liquid by reusing the coating liquid.

먼저, 상기 에어 블로잉(100)은 피도포재(10)의 이물질을 제거하는 것으로, 코팅 처리를 하기 위한 상기 피도포재(10)의 외면에 묻어있는 노폐물 또는 이물질을 제거하여 코팅 처리 시 상기 피도포재(10)에 노폐물 또는 이물질이 같이 코팅 처리되지 않도록 한다.First, the air blowing (100) is to remove the foreign matter of the coating material 10, to remove the waste or foreign matter on the outer surface of the coating material 10 for the coating treatment to remove the blood Waste material or foreign matter on the coating material 10 is not to be coated.

또한, 상기 피도포재(10)는 상기 에어 블로잉(100)에 세워진 상태로 투입되어, 상기 피도포재(10)의 양면의 이물질을 동시에 제거할 수 있다. In addition, the to-be-coated material 10 may be put in a standing state on the air blowing 100 to remove foreign substances on both sides of the to-be-coated material 10 at the same time.

다음으로, 상기 이송벨트(200)는 상기 에어 블로잉(100)의 선단에 위치하되, 상기 피도포재(10)가 올려지며, 상기 에어 블로잉(100)을 통해 이물질이 제거된 상기 피도포재(10)가 안착된다. 상기 에어 블로잉(100)에 세워진 상태로 투입된 상기 피도포재(10)가 상기 에어 블로잉(100)의 선단에서 상기 이송벨트(200)에 쓰러지도록 상기 이송벨트(200)의 단부에 지그(미도시)가 설치되는 것이 바람직하다.Next, the transfer belt 200 is located at the tip of the air blowing 100, the coating material 10 is raised, the foreign material is removed through the air blowing (100) 10) is seated. Jig (not shown) at the end of the conveying belt 200 so that the coated material 10 put in the standing state in the air blowing 100 falls on the conveying belt 200 at the tip of the air blowing 100. Is preferably installed.

종래의 그라비아 코팅 장치의 이송벨트는 줄 컨베이어로 형성되어, 피도포재가 줄 컨베이어에 끼어 손상되거나, 피도포재 또는 피도포재에 코팅된 코팅액이 바닥으로 떨어져 작업장이 오염되는 문제가 발생하여, 본 발명의 상기 이송벨트(200)는 면 컨베이어로 제작되어 상기 피도포재(10)가 안착될 수 있다.The transfer belt of the conventional gravure coating device is formed of a file conveyor, the coating material is damaged by the file conveyor, or the coating liquid coated on the coating material or the coating material falls to the floor and contaminates the workplace. The conveying belt 200 of the present invention may be manufactured by a cotton conveyor so that the coated material 10 may be seated.

그리고 상기 코팅액 침지통(300)은 상기 이송벨트(200)의 단부에 위치하며, 코팅액이 수용되되 측면에는 배출구(310)가 형성된다. 상기 배출구(310)는 상기 코팅액 침지통(300) 측면의 상부에 형성되어, 상기 코팅액 침지통(300)에 수용되는 코팅액의 양이 일정량 차오르면 후술할 상기 코팅액 보관통(600)으로 코팅액을 배출하게 된다.And the coating liquid immersion container 300 is located at the end of the transfer belt 200, the coating liquid is accommodated, but the discharge port 310 is formed on the side. The outlet 310 is formed on the upper side of the coating liquid immersion container 300, so that the coating liquid is discharged to the coating liquid storage container 600 to be described later when the amount of the coating liquid accommodated in the coating liquid immersion container 300 is filled up do.

다음으로, 상기 제1 롤러(400)는 상기 코팅액 침지통(300)의 상부에 결합되되, 코팅액에 침지되어 상기 피도포재(10)의 상부와 접촉되어 회전 구동되도록 형성되고, 상기 제2 롤러(500)는 상기 제1 롤러(400)의 상방향으로 일정간격 이격되어, 상기 피도포재의 하부와 접촉되어 회전 구동되도록 형성된다.Next, the first roller 400 is coupled to the upper portion of the coating liquid immersion container 300, is immersed in the coating liquid is formed to be in contact with the upper portion of the coating material 10 is driven to rotate, the second roller 500 is spaced apart by a predetermined interval in the upper direction of the first roller 400, is formed to be in contact with the lower portion of the coating material to be driven to rotate.

또한, 상기 제1 롤러(400)와 상기 제2 롤러(500)는 서로 다른 방향으로 회전되되, 외주면에는 부직포가 형성된다.In addition, the first roller 400 and the second roller 500 are rotated in different directions, the non-woven fabric is formed on the outer peripheral surface.

상기 피도포재(10)는 도 1에 도시된 바와 같이, 왼쪽에서 오른쪽으로 이송되고, 상기 제1 롤러(400)는 시계방향으로 회전하고, 상기 제2 롤러(500)는 반시계 방향으로 회전한다. As shown in FIG. 1, the coated material 10 is transferred from left to right, the first roller 400 rotates in a clockwise direction, and the second roller 500 rotates in a counterclockwise direction. do.

그리고 상기 제1 롤러(400)와 상기 제2 롤러(500)의 외주면에 부직포가 형성되어, 상기 피도포재(10)와 접촉되는 면적이 넓어져 코팅량을 증가시키는 효과가 있다.In addition, a nonwoven fabric is formed on the outer circumferential surfaces of the first roller 400 and the second roller 500, thereby increasing the area of contact with the to-be-coated material 10, thereby increasing the coating amount.

따라서, 상기 피도포재(10)의 주행방향과 상기 제1 롤러(400)의 회전되는 방향이 반대가 되어 리버스 키스(reverse kiss) 방법으로 상기 피도포재(10)의 하부면을 코팅할 수 있으며, 상기 피도포재(10)의 주행방향과 상기 제2 롤러(500)의 회전되는 방향이 반대가 되어 리버스 키스 방법으로 상기 피도포재(10)의 상부면을 코팅할 수 있다.Accordingly, the driving direction of the coated material 10 and the direction in which the first roller 400 is rotated are reversed to coat the lower surface of the coated material 10 by a reverse kiss method. In addition, the driving direction of the to-be-coated material 10 and the direction in which the second roller 500 is rotated to be reversed may coat the upper surface of the to-be-coated material 10 by a reverse kiss method.

상기 제1 롤러(400)는 외부에 부직포가 감겨진 상태로 상기 코팅액 침지통(300)에 수용된 코팅액에 일부 침지된 상태에서 회전하고, 상기 제2 롤러(500)는 후술할 상기 코팅액 분사 노즐(800)을 통해 외주면에 감겨진 부직포에 코팅액이 묻혀진다.The first roller 400 is rotated in a state of being partially immersed in the coating liquid accommodated in the coating liquid immersion container 300 while the nonwoven fabric is wound on the outside, the second roller 500 is the coating liquid spray nozzle (to be described later) The coating solution is buried in the nonwoven fabric wound on the outer circumferential surface through 800).
