Description

골심지가 격자형으로 적층된 골판지의 제조방법{The method to manufacture the corrugated cardboard with lattice-layered corrugated papers}The method to manufacture the corrugated cardboard with lattice-layered corrugated papers}

본 발명은 물품을 포장하는 박스 등의 소재로 사용되는 골판지에서 완충 역할을 하는 골심지가 격자형으로 형성되는 골판지의 제조방법에 관한 것으로, 보다 상세하게는 상·하의 파형롤러 표면에 요홈과 돌출부가 구성되며, 상호 맞물리게 조립하여 굴곡홈이 발생 되도록 형성시켜 표면이 평면 상태의 판지를 수평방향의 골심지 형상으로 완성시키고, 상기 골심지의 돌출부 표면에 화학풀을 완벽하게 도포시켜 격자형 골판지를 제조하는 방법에 관한 것이다.The present invention relates to a method for manufacturing a corrugated cardboard in which the corrugated cardboard, which serves as a buffer in a corrugated cardboard used as a material for packaging an article, is formed in a lattice shape, and more specifically, grooves and protrusions are formed on upper and lower corrugated roller surfaces. Consisting with each other to form a bent groove is formed by interlocking to complete the cardboard in the flat surface state of the shape of the horizontal corrugated core, the method of producing a lattice corrugated cardboard by completely applying a chemical paste on the surface of the protrusion of the corrugated medium It is about.

일반적으로 종래에는 도 1에서 도시된 바와 같이 외부로부터의 충격이나 압력을 완화시키기 위하여 표면지 사이에 삽입되는 상기 골심지는 판지에 골이 형성되게 구성한 후 골심지를 동일한 방향으로 적층되어 있는 바, 상기 골심지가 겹쳐지지 않도록 하기 위한 기술적 수단으로 골심지 사이에 중심지를 위치시키고, 골심지가 중심지와 표면지에 고착되도록 하여 외부로부터의 충격이나 압력을 완화할 수 있도록 구성하였다.Generally, as shown in FIG. 1, the corrugated medium inserted between surface papers in order to alleviate shock or pressure from the outside is configured to form a bone on a cardboard, and then the core cores are stacked in the same direction. As a technical means for avoiding overlapping, the center of gravity was placed between the core cores, and the core cores were fixed to the center and the surface of the core so as to mitigate the impact or pressure from the outside.

상기와 같이 완성되는 종래의 공정을 간단히 설명을 하면 다음과 같다.Brief description of the conventional process completed as described above is as follows.

수직 상부파형롤러와 수직 하부파형롤러를 상·하로 맞물리도록 구성하여 회전시키면서 판지를 투입시키면 상기 판지의 표면에는 굴곡홈이 수직으로 형성되며, 이어서 전분풀이 표면에 형성된 회전롤러에 의해 상기 판지의 돌출부 표면에 전분풀이 도포되도록 하였다.When the cardboard is inserted while rotating the vertical upper corrugated roller and the vertical lower corrugated roller up and down, the curved groove is vertically formed on the surface of the cardboard, and then the projection of the cardboard is formed by the rotating roller formed on the surface of the starch paste. Starch paste was applied to the surface.

그리고 상기와 같은 작업공정은 전분풀을 사용함으로 인해 건조시간과 건조속도가 늦어져 골판지의 생산을 최대화하지 못하는 단점이 있었다.In addition, the work process as described above has a disadvantage in that the production time of the cardboard is not maximized due to the slow drying time and the drying speed due to the use of starch paste.

또한 상기의 작업방식은 전분풀을 사용하므로 인해 골판지를 건조시키는 건조장치의 길이가 12M 이상으로 설치되어야 전분풀에 의해 골판지가 견고하게 부착될 수 있다.In addition, the above working method uses a starch paste, so that the corrugated cardboard may be firmly attached to the starch pool when the length of the drying device for drying the corrugated cardboard is installed to 12 m or more.

상기 방식과 같은 골심지를 동일한 방향으로 층을 형성시키는데 사용되는 접착제의 성분은 반드시 전분풀을 사용하고 있다.The component of the adhesive used to form the corrugated core in the same direction as in the above manner necessarily uses starch paste.

그 이유는 상기 파형롤러가 수직으로 형성되어 있고, 또한 풀이 함유된 롤러 또한 수직으로 회전하므로 인하여 상기 회전롤러 표면에 붙은 전분풀과 상기 파형 롤러에 의해 성형된 굴곡홈의 표면이 동일한 방향일 뿐 아니라 밀착되는 면이 짧아 순간적으로 스치고 지나가므로 전분풀이 굴곡홈의 표면에 도포되는 작업이 완벽하게 되지 못하고, 또한 회전되는 롤러에서는 전분풀이 사방으로 튀므로 인하여 주변 기계에 손상을 줄 뿐 아니라 작업후 바로 제거하여야 하는 번거로움이 발생된다.The reason is that since the corrugated roller is formed vertically, and the roller containing the grass also rotates vertically, the starch paste adhered to the rotating roller surface and the surface of the curved groove formed by the corrugated roller are not only in the same direction. Because the surface to be contacted is short and it passes by momentarily, the starch paste is not applied to the surface of the curved groove perfectly. Also, the starch paste splashes in all directions in the rotating roller, which not only damages the surrounding machinery but also removes it immediately after the operation. Hassle to be created.

그리고 이와 같은 공정에 접착력이 우수한 화학풀을 사용하게 되면 화학풀의 접착력 때문에 기계부품 등에 손상을 줄 뿐 아니라 이를 다시 제거하기가 대단히 어려우므로 화학풀 사용이 곤란한 단점이 있다.In addition, the use of a chemical paste having excellent adhesion in such a process not only damages the mechanical parts due to the adhesive strength of the chemical paste, but also makes it difficult to remove the chemical paste, which is difficult to use.

또한 상기 전분풀을 사용하므로 인하여 골판지를 완성시키는 시간이 화학풀보다 오랜시간이 소요되는데 이는 건조시간과 전분풀의 접착력에 관계가 있다.In addition, due to the use of the starch pool, the time required to complete the corrugated cardboard is longer than the chemical pool, which is related to the drying time and the adhesion of the starch pool.

상기의 같은 통상적인 파형롤러의 표면 굴곡홈은 수직으로 형성되어 있으므로 인해 판지의 표면에 만들어지는 굴곡홈 또한 수직방향으로 형성되고, 상기 굴심지는 동일한 방향으로 적층되므로 실제적으로 외부의 충격이나 압력으로부터 겹층된 만큼의 완충역할이 사실상 되지 않는 문제점이 있었다.Since the surface curved grooves of the conventional corrugated rollers are vertically formed, the curved grooves made on the surface of the cardboard are also formed in the vertical direction, and the curved cores are stacked in the same direction, so that they are actually laminated from external impact or pressure. There was a problem that the buffer role is not virtually as much.

본 발명은 상기의 종래 문제점을 해결하기 위하여 안출 한 것으로서, 수평 상부파형롤러와 수평 하부파형롤러 및 수직 상부파형롤러와 수직 하부파형롤러를 각각 한조로 구성하여 상호 교차시키는 수단과; 상기 수평, 수직 파형롤러의 표면에 요홈과 돌출부를 형성하는 수단과; 상기 수평, 수직 상부파형롤러가 상호 맞물리면서 굴곡홈이 형성되어 판지가 골심지로 형성되는 수단과; 골판지에 부착되는 화학풀이 강력하게 부착되게 짧은 거리에 건조기를 형성하여 골판지가 격자형으로 적층될 수 있도록 된 작업공정의 생산라인을 제공하는데 발명의 목적이 있다.The present invention has been made in order to solve the above problems, a horizontal upper waveform roller, a horizontal lower waveform roller, and a vertical upper waveform roller and a vertical lower waveform roller in a pair of means to cross each other; Means for forming grooves and protrusions on the surfaces of the horizontal and vertical corrugated rollers; A means in which the horizontal and vertical upper waveform rollers are engaged with each other to form a bent groove so that the cardboard is formed into a corrugated core; An object of the present invention is to provide a production line of a work process in which a dryer is formed at a short distance so that the chemical paste attached to the cardboard is strongly attached so that the cardboard can be stacked in a lattice form.

상기의 목적을 달성하기 위하여 생산 라인에는 상·하로 조립된 수평 파형롤러와 수직 파형롤러를 상호 교차시키거나, 아니면 같은 라인선에 형성시키고, 화학풀을 골판지에 도포시키는 롤러가 상기 파형롤러의 후면에 구성되도록 하여 골판지를 형성시키는 골심지를 격자형으로 적층하여 화학풀에 의해 접착되도록 구성한 골판지를 제공하고자 하는 것이다.In order to achieve the above object, the production line has a horizontal corrugated roller assembled vertically and vertically and vertical corrugated rollers intersected with each other, or formed on the same line, and a roller for applying a chemical paste to corrugated cardboard is formed on the back of the corrugated roller. It is intended to provide a corrugated cardboard configured to be bonded to the chemical core by laminating in a lattice form the corrugated cardboard to form a cardboard.

상기의 도면에서와 같이 최초 판지는 수평 파형롤러(10)를 통과하게 되면서돌출부(19)가 형성됨과 동시에 화학풀공급롤러(22)에 의해 상기 판지의 돌출부(19)표면과 저면은 화학풀로 도포되면서 지속적으로 가이드롤러(27)에 유입된다.As shown in the figure, the first cardboard passes through the horizontal corrugated roller 10, while the protrusion 19 is formed, and at the same time, the surface and the bottom of the protrusion 19 of the cardboard by the chemical pull feed roller 22 are chemically glued. It is continuously introduced into the guide roller 27 while being applied.

이때 상기의 수직 파형롤러(20)에서도 별도의 판지에 돌출부(19)를 형성시키고 화학풀공급롤러(22)를 통과시켜 돌출부(19)의 표면과 저면은 화학풀이 도포되면서 가이드롤러(27)에 유입된다.At this time, the vertical corrugation roller 20 also forms a protrusion 19 on a separate cardboard and passes the chemical pull feed roller 22 so that the surface and bottom of the protrusion 19 are coated with a chemical glue to the guide roller 27. Inflow.

그리고 상기의 작업진행과 동시에 표면지공급롤러(25)에서는 표면지(14)가 공급되어 수평 파형롤러(10)에서 형성된 돌출부(19)의 표면에 밀착되도록 하여 상기의 언급된 가이드롤러(27)에 유입되며, 또한 별개의 표면지(14)가 상기 가이드롤러(27)에 유입되면서 수직 파형롤러(20)에서 형성된 돌출부(19)의 저면에 밀착되어 접착되게 하였다.At the same time as the above operation, the surface paper feed roller 25 is supplied with the surface paper 14 so that the surface paper 14 is brought into close contact with the surface of the protrusion 19 formed in the horizontal corrugated roller 10. In addition, the separate surface paper 14 is introduced into the guide roller 27 while being adhered to and adhered to the bottom surface of the protrusion 19 formed in the vertical corrugated roller 20.

따라서 가이드롤러(27)에는 수평 파형롤러(10)와 수직 파형롤러(21)를 통과한 두개의 판지와 두개의 표면지(14)는 상호 교차되게 각 층을 이루면서 유입됨과 동시에 압착하여 하나의 골판지(17)형태로 완성되고, 건조기(12)를 통과하면서 화학풀의 수분이 빠져 강력하게 접착될 수 있는 것이다.Therefore, the two rollers and two surface papers 14 passing through the horizontal corrugated roller 10 and the vertical corrugated roller 21 are introduced into the guide rollers 27 to form each layer so as to cross each other, and at the same time, press one corrugated paper. Finished in the form (17), the moisture of the chemical pool can be pulled out and strongly bonded while passing through the dryer (12).

The surface of the projection 19 deformed to the surface of the chemical glue feed roller 22 and the chemical roller of the feed roller 22 can be applied to the surface of the protrusion 19 formed in the corrugated medium (15) do.

이상과 같이 구성된 본 발명의 작용에 대하여 상세히 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above in detail.

수평 파형롤러(10)와 수직 파형롤러(20)에 의해 완성된 골심지(15)의 표면 형상은 서로 상이한 격자 형태로 완성되어 적층시켜 고착되도록 구성하였다.The surface shape of the corrugated wick 15 completed by the horizontal corrugated roller 10 and the vertical corrugated roller 20 was completed in a lattice form different from each other, and was configured to be laminated and fixed.

상기 파형롤러(10)는 수평 상부파형롤러(10)와 수평 하부파형롤러(11)가 상호 맞물리게 하여 조립되어 회동하도록 하였다.The corrugated roller 10 was assembled by rotating the horizontal upper waveform roller 10 and the horizontal lower waveform roller 11 to be engaged with each other.

판지 공급롤러(23)에서 공급된 판지가 상기 수평 파형롤러(10)(11)의 사이를 통과하게 되면 수평으로 형성된 골심지(15)가 만들어지게 된다.When the cardboard supplied from the cardboard feed roller 23 passes between the horizontal corrugated rollers 10 and 11, the corrugated core 15 horizontally formed is made.

또한 수직 상부파형롤러(20)와 수직 하부파형롤러(21)가 상호 맞물리게 하여회동시키고 상기 판지를 통과시키면 수직으로 형성된 골심지(15)가 완성된다.In addition, the vertical upper corrugated roller 20 and the vertical lower corrugated roller 21 are rotated by interlocking with each other, and the corrugated core 15 vertically formed is completed by passing the cardboard.

상기와 같이 수평방향으로 형성된 골심지(15)와 수직방향으로 형성된 골심지(15)는 별개의 라인을 통해 이동하여 가이드롤라(27)에 진입할 수 있다.As described above, the bone wick 15 formed in the horizontal direction and the bone wick 15 formed in the vertical direction may move through separate lines to enter the guide rollers 27.

여기서 수평, 수직으로 형성된 골심지(15)의 돌출부(19) 표면과 저면에는 화학풀공급롤러(22)에 의해 화학풀이 도포되게 된다.Here, the chemical glue is applied to the surface and bottom of the protrusion 19 of the corrugated core 15 formed horizontally and vertically by the chemical glue feed roller 22.

그리고 골판지(17)의 외형을 이루는 표면지(14)가 또한 별개의 라인을 따라 가이드롤러(27)에 유입되게 된다.And the surface paper 14 forming the outline of the corrugated cardboard 17 is also introduced into the guide roller 27 along a separate line.

상기의 표면지(14)는 상·하로 형성되어 있으므로 두개의 표면지공급롤러(25)가 필요한다.Since the surface paper 14 is formed up and down, two surface paper feed rollers 25 are required.

가이드롤러(27)에는 이상과 같이 수직, 수평으로 형성된 골심지(15)가 격자형으로 유입되고, 또한 표면과 저면에 부착되는 표면지(14)가 두개의 층으로 형성되어 유입된다.The corrugated core 15 vertically and horizontally formed as described above is introduced into the guide roller 27 in a lattice shape, and the surface paper 14 attached to the surface and the bottom is formed into two layers.

따라서 상기 가이드롤러(27)는 일정한 압력이 발생되도록 롤러와 롤러를 조절할 수 있고, 골판지(17)의 표면을 압착하도록 하였다.Therefore, the guide roller 27 can adjust the roller and the roller so that a constant pressure is generated, it was to press the surface of the corrugated cardboard (17).

그리고 가이드롤러(27)를 통과한 골판지(27)는 수분이 많은 화학풀에 의하여 임시적으로 접착된 상태이고 이를 건조시켜야 한다.And the corrugated cardboard 27 that has passed through the guide roller 27 is temporarily bonded by a juicy chemical paste and should be dried.

상기 화학풀은 전분풀보다 수분이 매우 적고 건조되는 시간이 짧은 장점이 있으므로 골판지를 완성하는데 유리하다.The chemical paste is advantageous to complete the corrugated cardboard because it has the advantage of very little moisture and short drying time than the starch pool.

건조기(12) 내부에는 높은 온도가 유지되고, 상기의 건조기(12)는 일정한 형태와 길이로 이루어질 수 있는데 전분풀에 사용되는 건조기의 길이는 통상적으로12M 이상까지도 되는 반면 본 발명의 건조장치는 4∼5M가 타당한다.The high temperature is maintained inside the dryer 12, the dryer 12 may be of a constant shape and length, the length of the dryer used in the starch pool is typically up to 12M or more while the drying apparatus of the present invention is 4 -5M is valid.

판지가 파형롤러를 통과하게 되면서 굴심지의 돌출부가 형성됨과 동시에 풀공급롤러에 의해 상기 판지의 돌출부 표면과 저면은 화학풀로 도포되면서 지속적으로 가이드롤러에 유입되면서 골판지를 완성하게 된다.As the cardboard passes through the corrugated roller, the protrusion of the core core is formed, and at the same time, the protrusion surface and the bottom of the cardboard are applied to the chemical glue by the pull feed roller and continuously flow into the guide roller to complete the corrugated cardboard.

그리고 종래의 파형롤라는 수직방향으로만 형성되어 있는 것을 수평방향으로 변환하였고 또한 롤러의 표면에 형성되는 굴곡홈의 방향을 수평으로 형성시켜 화학풀이 골심지의 돌출부 쪽으로 확산되게 하므로 인하여 주변 환경이 깨끗하게 되는 특징이 있다.In addition, the conventional corrugated roller is converted only in the vertical direction to the horizontal direction, and the horizontal direction of the bending grooves formed on the surface of the roller is formed horizontally so that the chemical pool is diffused toward the protrusion of the corrugated core, thereby making the surrounding environment clean. There is a characteristic.

이와 같이 외부로부터의 충격이나 압력의 발생시 골판지의 완충력을 증진시키기 위해 표면지 사이에 골심지를 격자형으로 적층한 후 상기 골심지를 표면지나적층된 골심지와 고착되도록 결합하여 구성하였다.Thus, in order to enhance the buffering force of the corrugated cardboard in the event of impact or pressure from the outside, the corrugated cardboard was stacked in a lattice form between the corrugated cardboard, and the corrugated cardboard was configured to be fixed to the corrugated cardboard or the laminated corrugated cardboard.

상기와 같이 골심지를 격자형으로 적층하여 구성함으로서 외부로부터 압력의 발생시 골판지의 자체의 완충력으로 인해 내용물을 안전하게 보호할 수 있도록 하였다.By configuring the core core in a lattice form as described above, the contents of the corrugated cardboard can be safely protected due to the buffering force of the cardboard itself when pressure is generated from the outside.

화학풀을 사용함으로 인해 건조속도가 대폭 향상되어 골판지의 생산성이 매우 높아지는 특징과 함께 건조장치를 대형화에서 소형화시킬 수 있는 효과가 있고, 상기의 공정방식으로 골판지를 완성하였을 때 소요되는 풀의 소비를 크게 줄일 수 있고, 작업환경이 보다 청결하게 유지될 수 있는 효과가 있다.By using chemical paste, the drying speed is greatly improved, and the productivity of corrugated cardboard is greatly increased, and the drying apparatus can be miniaturized at large size. It can be greatly reduced and the working environment can be kept more clean.

그리고 골판지가 격자형으로 형성되어 외부의 충격이나 압력을 완화시키는효과가 있으며, 또한 골심지 사이에 중심지를 사용하지 않으므로 경제적인 효과가 부수적으로 있다.In addition, since the corrugated cardboard is formed in a lattice shape, there is an effect of alleviating external impact or pressure, and since the center is not used between corrugated cores, there is an additional economic effect.
