본 발명은 골판지의 성형방법에 관한 것으로, 특히 임의의 단면을 구비하여 포장재로 사용되는 골판지를 빠르고 안정된 상태로 연속 생산이 가능하도록 한 골판지의 성형방법에 관한 것이다.The present invention relates to a method for forming a corrugated cardboard, and more particularly, to a method for forming a corrugated cardboard having an arbitrary cross-section so as to enable continuous production in a fast and stable state.

일반적으로 골판지는 물건의 노출된 외부 표면을 보호하기 위한 포장에 사용되며 골판지의 L자형 단면은 창고에서의 보관이나 수송중에 금속 생산품의 양측면 및 모서리를 충격에 대해 보호하기 위하여 사용되는 것임은 이미 잘 알려진 사실이다.It is generally well known that corrugated cardboard is used for packaging to protect the exposed outer surfaces of objects, and the L-shaped cross section of corrugated cardboard is used to protect the sides and edges of metal products against impact during storage or transport in warehouses. It is a known fact.

그리고 골판지는 한쪽면만 L자형으로 골이 지도록 형성하여 골의 선을 따라 구부릴 수 있도록 하였다.And corrugated cardboard was formed so that only one side was L-shaped bone to bend along the line of the bone.

그러나 상기와 같은 종래의 골판지는 소정폭의 골판지를 필요한 두께만큼 원형으로 말아주고, 직각의 양면을 갖는 성형구와 이를 받쳐주는 받침부로 구성된 성형기를 사용하여 원형으로 말아진 종이를 L자형으로 절곡 형성하였으므로 안쪽으로 접히는 부위와 바깥쪽으로 접히는 부위에는 각각 다른 힘의 작용이 있게 되며 안쪽 부위에 주름 형상이 생기거나 바깥부위에서 터지는 현상이 발생하게 되고, 이에 따라 골판지를 원형으로 말아줄 때 그 두께가 커질 수 없으므로 골판지의 강도가 강하여지지 못하면서 두께도 작아지게 되는 등의 단점이 있었다.However, the conventional corrugated paper as described above was rolled into a circular paper of a predetermined width by the required thickness, and formed by bending the L-shaped paper rolled by using a molding machine consisting of a molding sphere having a right-sided both sides and the supporting portion supporting it. Inward and outward folds have different forces, and wrinkles or inner bursts occur on the inside, which can increase in thickness when the cardboard is rolled in a circle. Therefore, the strength of the corrugated cardboard was not strong, there was a disadvantage that the thickness is smaller.

이에 따라 본 발명은 골판지를 삼각로울러로 말아주고 임의의 형상으로 성형하도록 하여 두께에 관계없이 안정되고 빠른 작업의 수행이 가능하도록 한 골판지의 성형방법을 제공하는 것을 그 목적으로 한다.Accordingly, an object of the present invention is to provide a method for forming a corrugated cardboard that is rolled up in a triangular roller and molded into an arbitrary shape to enable stable and fast operation regardless of thickness.

이와 같은 목적을 달성하기 위한 본 발명은 소정폭의 골판지를 공급하면서 접착제를 발라주고, 접착제가 발라진 골판지는 롤링기로 이송되어 일측의 내각이 140° 정도인 이등변삼각형으로 배열된 삼각로울러에 의해 임의의 두께만큼 말아주도록 하고, 삼각로울러에 의해 말아진 골판지는 140°의 각을 갖는 받침부와 성형구가 구비된 제1성형기를 통과하는 중에 사이각이 140°인 V자형으로 되도록 하고, 다시 V자형으로 형성된 골판지를 직각의 받침부와 성형구가 구비된 제2성형기를 경유하는 중에 직각의 L자형으로 되도록 한 다음, 전열건조로에서 L자형으로 성형된 상태에서 건조되어 그 형상이 계속 유지되도록 함으로써, 말아진 골판지의 두께에 관계없이 빠르고 안정된 작업을 수행하도록 한 것이다.The present invention for achieving the above object is to apply an adhesive while supplying a corrugated cardboard of a predetermined width, the adhesive coated cardboard is transferred to a rolling machine by an optional triangular roller arranged in an isosceles triangle with an angle of 140 ° on one side. The corrugated paper rolled by the thickness of the triangular roller was made into a V-shape having an angle of 140 ° while passing through the first molding machine equipped with a supporting part having a angle of 140 ° and a molding tool. By forming the corrugated cardboard formed into the L-shape at right angles while passing through the second molding machine provided with a right angle support and a molding tool, and then dried in the L-shape in the heat-drying furnace to maintain the shape, Regardless of the thickness of the rolled cardboard to perform a fast and stable operation.

Rolling process to wind in the form of obtuse triangular prism.

둔각 삼각기둥의 형태로 감긴 골판지는 제1성형기(8)로 이송되어 제3도의 (가)에 도시한 것과 같이 사이각이 140°인 받침부(9)에 지지되도록 하고 역시 사이각이 140°인 역삼각형의 성형구(10)가 하향으로 소정의 힘을 갖고 이동하면서 눌러줌에 따라 사이각이 140°인 V자형으로 형성하는 제1성형공정을 수행한다.The corrugated paper wound in the form of an obtuse triangular prism is conveyed to the first molding machine 8 to be supported by the support 9 having an angle of 140 °, as shown in (a) of FIG. As the inverted triangular molding tool 10 is pressed downward while moving with a predetermined force, a first molding process of forming a V-shape having an angle of 140 ° is performed.

V자형으로 성형된 골판지는 제2성형기(11)로 이송되어 제3도의 (나)에 도시한 것과 같이 사이각이 직각인 받침부(12)에 지지되도록 하고 역시 사이각이 직각인 역삼각형의 성형구(13)가 하향으로 소정의 힘을 갖고 이동하면서 눌러줌에 따라 사이각이 직각인 L자형으로 형성하는 제2성형공정을 수행한다.The corrugated cardboard formed into a V-shape is transferred to the second molding machine 11 so as to be supported by the support 12 having a right angle between them as shown in (b) of FIG. 3, and an inverted triangle having a right angle between them. As the molding tool 13 is pressed downward while moving with a predetermined force, a second molding process of forming the L-shape having a right angle between them is performed.

L자형으로 성형된 골판지는 전열건조로(14)로 이송되어 접착제 도포의 공정에 발라진 접착제가 마르는 중에 L자형으로 성형된 상태에서 굳어지도록 함으로써 제5도의 (가)에 도시한 것과 같은 L자형 골판지 포장재를 임의의 두께로 제조할 수 있도록 한 것이다.The L-shaped corrugated cardboard is transferred to the electrothermal drying furnace 14 so that the adhesive applied to the process of applying the adhesive hardens in the L-shaped state while drying, and thus L-shaped corrugated cardboard as shown in Fig. 5A. The packaging material can be produced to any thickness.

그리고 롤링기(4)에서 삼각로울러(5)(6)(7)에 의해 둔각 삼각기둥의 형태로 감긴 골판지를 제4도의 (가)에 도시한 것과 같이 사각오목부위(16a)가 일체인 받침부(16)에 지지되도록 하면서 상기 사각오목부위(16a)에 결합되는 사각돌기(17a)가 일체인 성형구(17)가 승하강하는 제3성형기(15)에 의해 ㄷ자형으로 성형되도록 한 후 건조시킴으로써 제5도의 (나)에 도시한 것과 같은 ㄷ자형 골판지 포장재를 임의의 두께로 제조할 수 있게 된다.And a square recess 16a integrally supported as shown in Fig. 4A by corrugated cardboard wound in the form of an obtuse triangular prism by the triangular rollers 5, 6 and 7 in the rolling mill 4; After being supported by the part 16, the square projection 17a, which is coupled to the square concave portion 16a, is integrally molded into a U shape by the third molding machine 15 which is lifted up and down. By drying, the U-shaped corrugated cardboard packaging material as shown in Fig. 5B can be manufactured to an arbitrary thickness.

여기서 사각오목부위(16a)와 사각돌기(17a)는 폭과 두께의 조절이 가능하게 하면서 골판지의 두께에 적용하도록 한다.Here, the square concave portion 16a and the square protrusion 17a are applied to the thickness of the corrugated paper while allowing the width and the thickness to be adjusted.

또한 둔각 삼각기둥의 형태로 감긴 골판지를 제4도의 (나)에 도시한 것과 같은 요홈(19a)가 일체인 받침부(19)에 지지되도록 하면서 편편한 성형구(20)를 하강시키면 둔각 삼각기둥의 골판지의 하단이 받침부(19)의 요홈(19a)에 밀리는 제4성형기(18)에 의해 T자형으로 성형되도록 한 후, 건조시켜 제5도의 (다)에 도시한 것과 같은 T자형 골판지 포장재를 임의의 두께로 제조하여도 무방하다.In addition, if the corrugated paper wound in the form of an obtuse triangular prism is lowered in the flat molding sphere 20 while the groove 19a as shown in FIG. The lower end of the corrugated cardboard is molded into a T-shape by the fourth molding machine 18 pushed by the groove 19a of the support 19, and then dried to form a T-shaped corrugated cardboard packaging material as shown in FIG. You may manufacture in arbitrary thickness.

이 경우에는 받침부(19)의 요홈(19a)을 형성하는 양가이더(21)(21a)가 벌려졌다 오무라졌다 하도록 하여 T자형 골판지 포장재의 형상을 조절할 수 있다.In this case, the shape of the T-shaped corrugated cardboard packaging material can be adjusted by allowing both guiders 21 and 21a, which form the grooves 19a of the support 19, to be opened and closed.

즉, 처음에는 받침부(19)의 요홈(19a)이 벌려진 상태가 되도록 하여 편편한 성형구(20)를 하향이동시킨 후 양가이더(21)(21a)가 오무라지게 하는 과정에 의해 T자의 돌출정도를 조절할 수 있다.That is, at first, the groove 19a of the support 19 is opened to move the flat molding tool 20 downward so that both guiders 21 and 21a protrude. You can adjust the degree.

따라서 본 발명의 골판지의 성형방법에 의하여서는 골판지를 원하는 길이만큼 절단하고 접착제를 발라준 다음, 롤링기의 삼각로울러에 의해 둔각 삼각기둥의 형태로 말아진 골판지를 받침부와 성형구를 임의로 선택하면서 L자형, ㄷ자형 또는 T자형의 골판지 포장재를 성형하고, 건조시킴으로써 골판지를 포장재로 성형할 때 두께가 커지더라도 안정된 성형이 가능하도록 한 것이다.Therefore, according to the method of forming the corrugated cardboard of the present invention, after cutting the corrugated cardboard to a desired length and applying an adhesive, while arbitrarily selecting the supporting portion and the molding sphere of the corrugated cardboard rolled in the form of an obtuse triangular prism by a triangular roller of a rolling machine. By forming the L-shaped, U-shaped or T-shaped cardboard packaging material and drying, it is possible to make stable molding even when the thickness of the corrugated cardboard is formed into a packaging material.
