골판지 코팅 장치{apparatus for coating corrugated fiber board }Apparatus for coating corrugated fiber board

본 발명은 골판지 코팅 장치에 관한 것으로서, 보다 상세하게는 잔류농약과 같은 유해물질을 제거할 수 있는 코팅액을 골판지의 원판에 코팅하는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated board coating apparatus, and more particularly, to an apparatus for coating a corrugated board with a coating liquid capable of removing harmful substances such as residual pesticides.

골판지는 원판지(liner)에 파형의 골심지(corrugating medium)를 접착제로 붙여서 만든 판지이다.Corrugated cardboard is a cardboard made by adhering corrugating medium of corrugated paper to a liner.

이러한 골판지는 한국등록특허 제10-296926호에 개시되어 있다.This corrugated cardboard is disclosed in Korean Patent No. 10-296926.

상기 개시된 골판지 제조장치는, 롤상태의 골심지가 한 쌍의 톱니치차 사이로 공급되면, 그 톱니치차의 형상이 반복되어 V형상으로 골심지를 절곡성형하고, 상기 절곡 성형된 골심지의 산에 접착제용기 내의 접착제를 롤러로 도포하고, 상기 접착제가 도포된 골심지를 롤 상태에서 공급되는 원판지에 접착시키고, 상기 일측면에 원판지가 접착된 상태로 이송되는 편면 골판지의 노출된 골심의 산에 다시 롤러로 접착제용기 내의 접착제를 도포하고, 상기 접착제를 도포시킨 노출된 골심지에 다른 원판지를 접착하고, 상기 골심지의 양측면에 원판지를 모두 접착시킨 후에 열풍 가열 및 건조실로 통과시켜 접착력과 골심지 강도를 증강시키는 것으로 되어 있다.The corrugated cardboard manufacturing apparatus described above is characterized in that, when roll corrugated paper is supplied between a pair of toothed gears, the shape of the toothed gear is repeated so as to bend and form the corrugated paper in a V shape, The corrugated paper coated with the adhesive is adhered to an original paper sheet fed in a roll state and the exposed corrugated sheet of the single-sided corrugated paper conveyed in a state in which the original paper sheet is adhered to the one side surface, And then adhering different original paper sheets to the exposed corrugated paper to which the adhesive has been applied, adhering all of the original paperboard to both sides of the corrugated paper sheet, passing through hot air heating and drying chamber to increase the adhesive strength and corrugated paper strength.

골판지의 양면 중 포장시에 외면이 될 면에 인쇄를 할 경우에는, 외면이 될 원판지를 골심시에 접착시키 전에, 골판지 제조 장치에 연계된 한 쌍의 인쇄롤러에 의해 인쇄처리하는 것으로 되어 있다. In the case of printing on the surface of the corrugated cardboard which is to be the outer surface at the time of packaging, a printing process is performed by a pair of printing rollers connected to the corrugated cardboard manufacturing apparatus before adhering the original paperboard to be the outer surface.

그 이유는, 골판지가 완성된 후, 상기 한 쌍의 인쇄롤러에 의해, 외면이 될 원판지에 인쇄처리하게 되면, 상기 한 쌍의 인쇄롤러에 의해 골심지가 가압을 받아 납작하게 변형되기 때문이다.This is because, after the corrugated cardboard is completed, the pair of printing rollers cause the corrugated paper to be deformed flatly by the pair of printing rollers when subjected to the printing process on the original paperboard to be the outer surface.

이러한 사정에 감안하여, 본 발명자는 한국 특허 공개 10-2017-0021930호에 개시된 잔류농약과 같은 유해물질을 제거할 수 있는 용액을, 기존 인쇄방법과 같이, 기존 골판지 제조장치에서 골판지 제조공정 전에, 내면이 될 원판지에 코팅하려고 하였지만, 기존 골판지의 규격이 각기 달라 이에 따른 골판지 제조 장치에 연계된 원판지 코팅 장치도 골판지의 규격 별로로 필요하게 되어 골판지에 상기 코팅액을 코팅하기 위한 제조장치의 비용이 증대된다고 하는 문제점을 가진다.In view of such circumstances, the inventor of the present invention has proposed a method for removing harmful substances such as residual pesticides disclosed in Korean Patent Publication No. 10-2017-0021930, However, since the conventional corrugated cardboard has different specifications, a cardboard coating apparatus connected to the corrugated cardboard manufacturing apparatus is also required according to the corrugated cardboard specifications, so that the cost of the manufacturing apparatus for coating the corrugated cardboard with the coating liquid There is a problem that it is increased.

이러한 문제점을 해결하기 위해, 골판지 제조장치에서 만들어진 각종 규격의 골판지를 별도의 코팅장치에 의해 골판지의 내면에 코팅하는 것이 고려되지만, 기존 코팅장치는, 인쇄장치와 같이, 한 쌍의 롤러에 의해 골판지를 가압하면서 이송시키면서 한 쌍의 롤러 중 하나의 롤러에 도포된 코팅액을 골판지에 인계하여 골판지를 코팅하는 것이어서, 한 쌍의 롤러에 의해 가압을 받고 있는 골판지의 골심지의 골기 낮작하게 변형된다고 하는 문제점을 가진다.In order to solve such a problem, it is considered to coat corrugated paper of various sizes made by the corrugated cardboard manufacturing apparatus on the inner surface of the corrugated cardboard with a separate coating apparatus. However, in the conventional coating apparatus, The corrugated cardboard of the corrugated cardboard which is being pressed by the pair of rollers is deformed in a simple manner by coating the corrugated cardboard with the coating liquid applied to one roller of the pair of rollers while pressing the corrugated cardboard with pressure. I have.

In the present invention, a negative pressure is applied to the lower side of a first conveyor porous belt moving in an endless track, and a coating roller coated with a coating liquid on the outer circumferential surface of the corrugated cardboard is brought into contact with the bottom surface of the corrugated cardboard, A negative pressure is applied to a lower side of a second conveyor porous belt for performing endless orbital movement of the unfolded corrugated cardboard which has been coated in the application portion and the lower side of the corrugated cardboard is arranged to face the bottom face of the coated corrugated cardboard And a drying unit for exposing a bottom surface of the coated corrugated cardboard to hot air generated by the hot air generator to dry the coating liquid applied to the bottom of the corrugated cardboard.

본 발명은 상기와 같은 과제해결수단에 의해, 골판지를 가압하지 않고서도 골판지의 일면에 코팅액을 도포시키는 것이 가능하여, 농산물을 포장하는 포장박스에 적용되는 골판지의 코팅액으로 하여금 농산물에 함유된 잔류농약과 같은 유해물질을 보관 중이나 운반 중에 제거하게 할 수 있다. According to the present invention, it is possible to apply the coating liquid to one side of a corrugated cardboard without pressurizing the corrugated cardboard, so that the coating liquid of corrugated cardboard, which is applied to a packaging box for packaging agricultural products, And may be removed during transport or storage.

이어서, 상기 도포된 상기 골판지(1)가 상기 다공벨트(22)의 부분(22a)에 의해 더 전진하여 다음의 건조부(30)에 있는 상기 다공벨트(32)의 부분(33a) 밑으로 이송되어, 부압이 걸린 상기 다공벨트(32)의 부분(32a)에 흡착되어서 상기 다공벨트(32)의 무한궤도 운동의 궤적으로 따라 전진하게 되면서, 열풍공급팬(35)에 의해 토출되는 열풍에 골판지(1)의 밑면이 접촉하여, 상기 골판지(1)의 밑면에 코팅액이 건조처리되게 된다.The corrugated cardboard 1 thus applied is further advanced by the portion 22a of the porous belt 22 to be conveyed below the portion 33a of the porous belt 32 in the next drying portion 30 And is adsorbed by the portion 32a of the porous belt 32 on which the negative pressure is applied so as to advance along the trajectory of the endless track of the porous belt 32. The hot air discharged by the hot air supply fan 35, The bottom surface of the corrugated cardboard 1 is brought into contact with the bottom surface of the corrugated cardboard 1, and the coating liquid is dried on the bottom surface of the corrugated cardboard 1.

이어서, 상기 건조된 상기 골판지(1)가 상기 다공벨트(22)의 부분(22a)에 의해 더 전진하여 다음의 적층부(40)의 테이블(41) 상에 얹어 놓이게 된다. 이때에 상기 적층부(40)의 리프터(42)는 상기 테이블(41)을 상기 골판지(1)와 상기 골판지(1)의 밑면에 도포되어 건조된 코팅층의 두께을 합한 두께만큼 반복적으로 하강하여, 다음의 골판지(1)가 상기 테이블(41) 위에 얹어 놓인 상기 골판지(1) 위에 얹어 놓일 수 있는 여유공간을 확보하게 된다.The dried corrugated cardboard 1 is then further advanced by the portion 22a of the porous belt 22 and placed on the table 41 of the next lamination portion 40. At this time, the lifter 42 of the lamination portion 40 lowers the table 41 repeatedly by the sum of the thickness of the dried coating layer applied to the corrugated cardboard 1 and the bottom surface of the corrugated cardboard 1, The corrugated cardboard 1 of the present invention secures a clearance space that can be placed on the corrugated cardboard 1 placed on the table 41.

상기와 같이 구성된 골판지 코팅 장치(100)에 의하면, 골판지(1)를 가압하지 않고서도 골판지의 일면에 코팅액을 도포시키는 것이 가능하여, 농산물을 포장하는 포장박스에 적용되는 골판지의 코팅액으로 하여금 농산물에 함유된 잔류농약과 같은 유해물질을 보관 중이나 운반 중에 제거하게 할 수 있다. According to the corrugated cardboard coating apparatus 100 configured as described above, it is possible to apply the coating liquid to one side of the corrugated cardboard without pressing the corrugated cardboard 1, thereby enabling the coating liquid of corrugated cardboard, which is applied to a packaging box for packing agricultural products, Hazardous substances, such as pesticide residues, may be removed during storage or transport.
