Description

재활용 골판지 {recycled corrugated paper}Recycled corrugated paper {recycled corrugated paper}

본 발명은 폐기 수거된 골판지박스를 절단하여 골판지만을 분리한 후 이를 다시 골판지박스로 재활용하는 것에 관한 것으로 더욱 상세하게는 분리된 골판지에 이미 형성되어 있는 장골을 메워서 완성하는 재활용 골판지에 관한 것이다. The present invention relates to recycling corrugated cardboard boxes by cutting discarded corrugated cardboard boxes to separate only the corrugated cardboard boxes, and more particularly, to recycled corrugated cardboard completed by filling long bones already formed in the separated corrugated cardboard boxes.

일반적으로 골판지는 원판지에 파형의 골심지를 접착제로 붙여서 만든 판지로서 편면골판지 양면골판지 이중양면골판지 삼중양면 골판지로 나뉘어진다. In general, corrugated cardboard is a cardboard made by attaching a corrugated core of a corrugated form to an original cardboard with an adhesive, and is divided into single-sided corrugated cardboard, double-sided corrugated cardboard, double-sided corrugated cardboard, and triple-sided corrugated cardboard.

골판지는 비교적 적은 무게의 재료를 사용하면서도 높은 압축강도를 나타낸다는 장점이 있는데 골판지중 원판지 사이에 구비되는 골심지는 골판지에 두께를 부여하고 견고성과 유연성을 증가시키는 동시에 충격시 압축에 대한 상대적인 탄성을 제공하기 때문이다. Corrugated board has the advantage of using a material with a relatively low weight and exhibiting high compressive strength. Among the corrugated board, the corrugated medium provided between the originals gives thickness to the corrugated board, increases rigidity and flexibility, and at the same time increases relative elasticity against compression during impact. because it provides

우수한 완충기능에 연유하여 골판지는 물건을 포장하는 박스로 많이 활용되고 있다. 그러나 이러한 골판지박스들은 대부분 1회 사용 후 폐기물로 버려지고 있다. 골판지 박스의 원료가 되는 골판지를 만들기 위해서는 나무를 베어야하며 나무의 펄프를 가공하는 과정에서 화공약품을 사용하게 됨으로 자원낭비와 환경오염 문제가 심각하다고 할 수 있다. 이에 폐기되는 골판지박스를 수거하여 골판지를 재생산하는 방법이 사용되고 있으나 이 역시 해리공정(폐지를 뜨거운 물에 풀어 분쇄하고 이물질을 1차적으로 제거하는 과정), 스크린공정(원통모양의 바스켓에서 얇은 틈으로 원료를 통과시켜 이물질을 제거하는 과정), 클리닝공정(원심분리식 방법을 통해 미세모레와 먼지를 제거하는 과정)등 정선 과정을 거치고 이후에도 농축공정(초지의 농도를 맞추는 과정)과 고해공정(원료의 섬유질 길이를 적절한 크기로 자르는 과정), 중약공정(원료에 지력증강제와 보류제를 첨가하는 과정) 등의 과정을 거쳐 골판지로 재생산 되는 과정에서 많은 비용이 발생되는 문제점이 있었다. Due to its excellent buffering function, corrugated cardboard is widely used as a box for packing goods. However, most of these cardboard boxes are discarded as waste after being used once. In order to make corrugated cardboard, which is the raw material of corrugated cardboard boxes, trees must be cut down, and chemicals are used in the process of processing the pulp of trees, so resource waste and environmental pollution problems are serious. Accordingly, a method of reproducing corrugated cardboard by collecting discarded cardboard boxes is used, but these are also used in the dissociation process (a process of dissolving waste paper in hot water and crushing it, and removing foreign substances primarily), screen process (a thin gap in a cylindrical basket). After going through selection processes such as the process of removing foreign substances by passing raw materials), cleaning process (process of removing fine sand and dust through centrifugal separation method), and then the concentration process (process of adjusting the concentration of the paper) and refining process (raw material) There was a problem in that a lot of cost was incurred in the process of reproducing into corrugated cardboard through processes such as the process of cutting the fiber length to an appropriate size) and the Chinese medicine process (the process of adding strength enhancers and retention agents to raw materials).

본 발명에서는 상기의 문제점을 해결하기 위해서 안출된 것으로서 상기의 해리공정, 스크린공정, 클리닝공정, 농축공정, 고해공정, 중약공정을 거치지 않아 오폐수 발생의 우려가 없는 재활용 골판지를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and the purpose is to provide recycled corrugated cardboard that does not have to go through the dissociation process, screen process, cleaning process, concentration process, beating process, and Chinese medicine process without worrying about the generation of wastewater. .

본 발명은 폐기 수거된 골판지박스를 절단하여 골판지만을 분리한 후 이를 다시 골판지박스를 만드는 용도로 재활용 것에 관한 것으로 더욱 상세하게는 분리된 골판지에 이미 형성되어 있는 장골(2-1)을 골판지패드(100)로 메워서 완성하는 재활용 골판지(1)에 관한 것이다. The present invention relates to cutting waste collected corrugated cardboard boxes to separate only corrugated cardboard and then recycling them for use in making corrugated cardboard boxes. It relates to a recycled corrugated cardboard (1) filled with 100).

상기와 같은 목적을 달성하기 위한 본 발명, 즉 재활용 골판지(1)의 구성을 설명하기 위해 이에 사용되는 골판지 혹은 골판지 박스 관련 용어 즉, 장골(2-1), 검 테이프, 괴선(2-2), 라이너지, 표면지, 목형, 도무송 등을 정의하면 다음과 같다.The present invention for achieving the above object, that is, the terms related to corrugated cardboard or corrugated cardboard boxes used therein to describe the configuration of the recycled corrugated cardboard (1), that is, the long bone (2-1), the gum tape, the thick line (2-2) , liner paper, surface paper, wooden pattern, domusong, etc. are defined as follows.

우선, 여기서 사용되는 '장골(2-1)' 이란 골판지 박스를 전개도 모양으로 펼쳤을 때 위와 아래에 골판지 박스의 상하 덮개에 해당되는 부분이 있는데 덮개는 가로 덮개와 세로덮개로 나뉜다. 가로덮개와 세로덮개 사이에는 틈이 형성되어 있는데 본 발명에서는 이 틈을 '장골(2-1)'이라 명명한다. First of all, when a cardboard box called 'Ilium (2-1)' used here is unfolded in the shape of a development, there are parts corresponding to the upper and lower covers of the cardboard box at the top and bottom, and the cover is divided into a horizontal cover and a vertical cover. There is a gap formed between the horizontal cover and the vertical cover, in the present invention, this gap is named 'ilium (2-1)'.

'검 테이프' 란 용어는 종이, 포 등을 기재로 하여 물에 적셨을 때 점착성을 발휘하는 테이프를 의미하며, '괴선(2-2)'이란 골판지 박스를 용이하게 접을 수 있도록 접히는 선을 따라 미리 골을 형성하는데 이 골을 본 발명에서는 '괴선(2-2)'이라 한다. The term 'gum tape' refers to a tape that exhibits adhesiveness when wetted with water using paper, cloth, etc. A bone is formed in advance, and this bone is referred to as a 'blind line (2-2)' in the present invention.

'라이너지'와 '표면지' 란 골판지는 원지를 파형으로 구부린 후 양쪽 면에 평평한 원지를 붙임으로써 만들어지는데 양쪽 면 중 박스 바깥쪽에 해당되는 면에 붙이는 원지를 ‘표면지’라 하고, 박스 안쪽에 해당되는 면에 붙이는 원지를 ‘라이너지’라고 한다. 일반적으로 ‘표면지’는 질기고 습기에 강하고 인쇄가 잘 되는 특징이 있으며 ‘라이너지’는 표면이 거칠어 인쇄가 잘 되지 않으며 습기에도 약한 반면 가격이 저렴하다는 장점이 있다. '목형'이란 합판에 박스 전개도 모양으로 칼날을 심은 것이며 '도무송'이란 '톰슨'이라고도 하는데 목형을 골판지 위에 덮어놓고 압력을 주어 골판지 박스 전개도 모양으로 절단 및 괴선(2-2) 형성 작업을 하는 것을 의미한다. Corrugated cardboard called 'Liner Paper' and 'Surface Paper' is made by bending the base paper into a waveform and attaching flat base paper to both sides. The base paper attached to the corresponding side is called 'liner paper'. In general, ‘surface paper’ is characterized by being tough, resistant to moisture, and prints well, while ‘liner paper’ has a rough surface, so it does not print well, is weak against moisture, and has the advantage of being inexpensive. 'Wood mold' is a knife blade planted in the shape of a box development on plywood, and 'Domusong' is also called 'Thompson'. means that

이하 설명에서는 또 본 발명의 내용을 이해하는데 필요한 부분만이 설명되며, 그 이외 부분의 설명은 본 발명의 요지를 흩트리지 않도록 생략될 것이라는 것을 유의하여야 한다.It should be noted that in the following description, only parts necessary for understanding the contents of the present invention are described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention.

또한 본 명세서 및 청구범위에 사용된 용어나 단어는 발명자가 자신의 발명을 설명하는 과정에서 임의로 정의하였음을 참조하여야 한다,In addition, it should be noted that the terms or words used in this specification and claims are arbitrarily defined by the inventor in the process of describing his/her invention.

이상에서는 본 발명의 설명에 사용되는 용어를 정의하였으며, 이하에서는 본 발명 재활용 골판지(1)의 생산과정 및 구조에 대해 살펴보기로 한다.In the above, terms used in the description of the present invention have been defined, and hereinafter, the production process and structure of the recycled corrugated cardboard 1 of the present invention will be described.

상기 도 3, 4 에 나타난 바와 같이, 본 발명 재활용 골판지(1)에서는 골판지패드(100)가 구비됨을 특징으로 한다.As shown in FIGS. 3 and 4, the recycled corrugated cardboard (1) of the present invention is characterized in that a corrugated cardboard pad (100) is provided.

우선, 재활용 골판지(1) 박스를 제조하기 위해 폐 골판지 박스를 수거한다. 이때 가급적 훼손되지 않고 청결한 상태로 수거하는 것이 바람직하다. 수거된 골판지 박스 양끝 즉 연결부위를 적당히 절단하여 철심(2-3)을 제거한다. 연결부위를 절단하면 가운데 순수 골판지 부분만 남게 되는데 본 발명에서는 이를 ‘1차 골판지(2)’라고 명명한다. ‘1차 골판지(2)’에는 도1에서와 같이 장골(2-1)이 형성되어 있어 이를 그 상태로 재활용하는 것이 매우 불편하게 된다. 본 발명에서는 장골(2-1)을 메워 불편함을 해결하는 수단이 제공되는데 장골(2-1)을 메운 골판지를 본 발명에서는 ‘2차 골판지’라 명명하기로 하고 ‘2차 골판지’는 다시 골판지박스를 제조하는데 재활용된다. 이하에서는 장골(2-1)을 메워 ‘2차 골판지’로 만드는 과정을 상세히 설명하면 다음과 같다. First, waste corrugated cardboard boxes are collected to manufacture recycled corrugated cardboard (1) boxes. At this time, it is desirable to collect it in a clean state without damage as much as possible. The iron core 2-3 is removed by appropriately cutting both ends of the collected corrugated cardboard box, that is, the connection part. When the connecting portion is cut, only the pure corrugated cardboard portion remains in the middle, which is referred to as 'primary corrugated cardboard (2)' in the present invention. As shown in FIG. 1, the ilium 2-1 is formed in the 'primary corrugated cardboard 2', so it is very inconvenient to recycle it in that state. In the present invention, a means to solve the inconvenience by filling the ilium 2-1 is provided. The corrugated cardboard filled with the ilium 2-1 is named 'secondary corrugated cardboard' in the present invention, and 'secondary corrugated cardboard' is again It is recycled to make cardboard boxes. Hereinafter, a detailed description of the process of filling the long bones (2-1) to make 'secondary corrugated cardboard' is as follows.

상기에서와 같이‘1차 골판지(2)’에는 장골(2-1)이 형성되어 있는데 장골(2-1)은 박스를 접기 위해 필수적으로 구비되어야 하나 수거된 박스들의 종류가 달라 장골(2-1)들의 폭, 길이, 위치도 제각기 달라 골판지를 재활용하는데 장애가 된다. 골판지를 효율적으로 재활용하기 위해서는 먼저 장골(2-1)을 메워야 하는데 본 발명에서는 골판지패드(100)가 사용된다. 골판지패드(100)는 적당한 두께의 골판지 혹은 골판지와 유사한 탄성체를 재단함으로써 만들어지는데 긴 띠모양의 패드바디(100-1)와 다수 개의 삼각돌기(100-2)가 패드바디(100-1)의 측면에 형성되며 삼각돌기(100-2)에는 수용성인 녹말풀이 도포되어 건조된 상태로 사용된다. 앞서 언급한 바와 같이 장골(2-1)은 박스에 따라 폭과 길이가 제각기 다를 수 있으며 이러한 장골(2-1)에 골판지패드(100)를 삽입하여 메우기 위해 과정을 살펴보면 장골(2-1)의 폭이 넓을 때는 삼각돌기(100-2)의 모서리 끝이 거의 눌려지지 않은 상태로 끼워지게 되며 장골(2-1)의 폭이 좁을 때는 삼각돌기(100-2)의 모서리 끝이 납작하게 눌려지면서 끼워지게 된다. 장골(2-1)의 길이가 길 때에는 골판지패드(100)를 이어붙임으로서 해결할 수 있다. 결과적으로 장골(2-1)의 폭 혹은 길이와 관계없이 골판지패드(100)를 사용하여 장골(2-1)을 메울 수 있게 되는 것이다. 장골(2-1)을 메운 이후 메운 자리를 도5와 같이 접착 테이프(200)로 도포하면 ‘2차 골판지’ 즉, 본 발명의 재활용 골판지(1)가 완성되게 된다. 이때 접착 테이프(200)용도로 검 테이프를 사용하면 검 테이프에 도포된 물은 골판지패드(100) 삼각돌기(100-2)의 녹말 접착제에 전달되어 그 결과 골판지패드(100)는 골판지와 접착되어 더욱 견고하게 고정되게 된다. 이후 본 발명의 재활용 골판지(1)로 박스를 제작할 때는 안쪽 면과 바깥쪽 면이 바뀌는 경우가 많은데 이 경우, 라이너지의 특성으로 인해 인쇄가 되지 않거나 습기게 취약하게 되는 등의 문제점이 발생한다. 이를 해결하기 위해서는 상기의 테이핑 대신 골판지의 안쪽 면 즉 라이너지가 도포되어 있는 면에 표면지를 새로 도포하면 ‘2차 골판지’는 더욱 견고하고 인쇄도 잘 되는 재생 골판지가 되는 것이다. 이러한 과정을 거쳐 완성된 본 발명의 ‘2차 골판지’ 즉, 재생 골판지는 박스 공장으로 옮겨져 도무송 등의 작업을 거쳐 박스로 재활용 될 수 있게 되는 것이다. As described above, the ilium 2-1 is formed in the 'primary corrugated cardboard 2'. The ilium 2-1 must be provided in order to fold the box, but the types of collected boxes are different. 1) The width, length, and location of each are different, which is an obstacle to recycling corrugated cardboard. In order to efficiently recycle the corrugated cardboard, first, the long bones 2-1 must be filled. In the present invention, the corrugated cardboard pad 100 is used. The corrugated cardboard pad 100 is made by cutting corrugated cardboard of appropriate thickness or an elastic body similar to corrugated cardboard. It is formed on the side, and water-soluble starch paste is applied to the triangular projections 100-2 and used in a dried state. As mentioned above, the ilium (2-1) may have different widths and lengths depending on the box, and looking at the process of inserting the cardboard pad (100) into the ilium (2-1) to fill it, the ilium (2-1) When the width of the triangular process (100-2) is wide, the edge of the triangular process (100-2) is inserted in a state where it is hardly pressed, and when the width of the ilium (2-1) is narrow, the edge of the edge of the triangular process (100-2) is pressed flat. It gets plugged in as you go. When the length of the long bone (2-1) is long, it can be solved by attaching the corrugated cardboard pad (100). As a result, the long bone 2-1 can be filled using the corrugated cardboard pad 100 regardless of the width or length of the long bone 2-1. After filling the ilium 2-1, if the filled position is coated with adhesive tape 200 as shown in FIG. 5, the 'secondary corrugated cardboard', that is, the recycled corrugated cardboard 1 of the present invention is completed. At this time, when gum tape is used for the adhesive tape 200, the water applied to the gum tape is transferred to the starch adhesive of the triangular projection 100-2 of the corrugated cardboard pad 100, and as a result, the corrugated cardboard pad 100 adheres to the corrugated cardboard. more firmly fixed. Since then, when making a box with the recycled corrugated cardboard 1 of the present invention, the inner and outer surfaces are often swapped. In this case, problems such as not being printed or being vulnerable to moisture occur due to the characteristics of the liner paper. In order to solve this problem, if the surface paper is newly applied to the inside surface of the corrugated cardboard, that is, the surface where the liner paper is applied instead of the above taping, the 'secondary corrugated cardboard' becomes a recycled corrugated cardboard that is more durable and prints well. The 'secondary corrugated cardboard' of the present invention completed through this process, that is, recycled corrugated cardboard, is transferred to a box factory and can be recycled into boxes through operations such as transportation.
