Description

폴드형 골판지 제조장치 {Fold Type Corrugated Cardboard Manufacturing Device}Fold Type Corrugated Cardboard Manufacturing Device}

본 발명은 골판지 제조장치에 관한 것으로, 보다 상세하게는 대형 가전, 가구, 건축자재, 산업기계 등과 같은 대형 물품의 포장용이나 건축용 등으로 편리하게 사용할 수 있는 폴드형 골판지 제조장치에 관한 것이다.The present invention relates to a corrugated cardboard manufacturing apparatus, and more particularly, to a fold-type corrugated cardboard manufacturing apparatus that can be conveniently used for packaging or construction of large articles such as large home appliances, furniture, building materials, and industrial machines.

일반적으로 골판지 생산공장에서 생산된 골판지는 접이식 포장상자로 만들어 출하되거나 또는 일정 길이씩 절단하여 사각형으로 형성한 평판형 골판지, 원통형으로 둘둘 말아서 길게 형성한 롤(roll)형 골판지 등으로 제품화하여 출하된다.In general, the corrugated cardboard produced at the corrugated cardboard production plant is shipped as a foldable packaging box, or a flat corrugated cardboard that is cut to a certain length and formed into a rectangle, or a roll-type corrugated cardboard that is rolled up into a cylindrical shape and formed into a long product and shipped. .

평판형 골판지 제품이나 롤형 골판지 제품은 포장용, 덮개용, 보호용, 단열용, 건축용 등 매우 다양하게 활용될 수 있다.Flat-type corrugated cardboard products or roll-type corrugated cardboard products can be used in a wide variety of ways, such as packaging, cover, protection, insulation, and construction.

평판형 골판지 제품은 길이가 정해져 있으므로 소량 구매가 가능하고 취급이 용이한 장점은 있으나, 크기가 대형인 냉장고, 세탁기, 가구, 건축자재, 산업기계 등의 물품을 포장하거나 벽체, 바닥 등을 임시 보호하는 용도나 단열용, 건축용 등에 사용하는 등의 경우 길이가 길어야 하므로 테이프 등으로 연결하면서 사용해야 하는 불편함이 있다.Flat corrugated cardboard products have a fixed length, so they can be purchased in small quantities and are easy to handle. In the case of using it for a purpose such as heat insulation, construction, etc., it is inconvenient to use it while connecting it with a tape, etc. because it has to be long.

반면에, 롤형 골판지는 사용자가 원하는 길이만큼씩 잘라서 사용할 수 있는 장점이 있으나, 롤형태로 둥글게 말기 위해 골심지의 한쪽에 라이너지가 설치된 편면 골판지 형태로 제조되어 출하됨에 따라 양면 골판지에 비해 강도, 보온성 등이 취약하므로 포장용으로 사용하기 어렵고 활용도가 낮다.On the other hand, roll-type corrugated cardboard has the advantage that it can be cut and used by the user as long as desired, but as it is manufactured and shipped in the form of single-sided corrugated cardboard with a liner paper installed on one side of the corrugated paper to roll it into a round shape, strength, warmth, etc., compared to double-sided corrugated cardboard, etc. Because of this weakness, it is difficult to use for packaging and the utilization is low.

한편, 대부분의 골판지는 단면상으로 가운데에 골심지가 설치되고 골심지의 양측에 각각 라이닝지가 접합되는 양면 골판지로 구성되며, 포장용 상자 등으로 사용하기 위해서는 일측의 라이닝지에 필요한 내용이 인쇄되어 있다.On the other hand, most corrugated cardboard is composed of double-sided corrugated cardboard in which a corrugated core is installed in the middle in cross-section and lining paper is bonded to both sides of the corrugated paper, and the necessary contents are printed on one side of the lining to be used as a packaging box.

이러한 골판지를 제조하기 위한 기술의 일예가 하기 문헌 1에 개시되어 있다.An example of a technique for manufacturing such a corrugated cardboard is disclosed in Document 1 below.
