상기 소정모양으로 재단되지 않은 판지형상의 플라스틱골판지(100)를 상·하부금형(210,220) 사이에 위치시킨 다음, 상부금형(210)을 하강시켜 하부금형(220)의 대응되는 위치에 맞닿게 한다(도 2b 참조).Place the cardboard-shaped plastic corrugated cardboard 100 that is not cut into a predetermined shape between the upper and lower molds 210 and 220, and then lowers the upper mold 210 to contact the corresponding position of the lower mold 220. (See FIG. 2B).

상기 상부금형(210)을 더욱 하강시켜 플라스틱골판지(100)의 가장자리에 일정한 압력을 가하면서 상부 융착면(230)이 플라스틱골판지(100)의 상부 판재(110) 를 용융시키고, 하부 금형(220)의 하부 융착면(240)이 상기 플라스틱골판지(100)의 하부 판재(120)를 용융시키면서, 상부 판재(110)와 하부 판재(120)가 접합되게 하여 마감부(150)를 형성시킨다(도 2c 참조).Lowering the upper mold 210 further, while applying a constant pressure to the edge of the plastic corrugated cardboard 100, the upper fusion surface 230 melts the upper plate 110 of the plastic corrugated cardboard 100, the lower mold 220 While the lower fusion surface 240 melts the lower plate member 120 of the plastic corrugated cardboard 100, the upper plate member 110 and the lower plate member 120 are joined to form a finish 150 (FIG. 2C). Reference).

이때, 상기 상부금형(210)의 상부 융착면(230)과 하부금형(220)의 하부 융착면(240)은 상·하부열선(212,220)에 의해 130∼150℃ 온도로 가열되어 5∼10초 동안 열융착된다.At this time, the upper fusion surface 230 of the upper mold 210 and the lower fusion surface 240 of the lower mold 220 is heated to a temperature of 130 ~ 150 ℃ by upper and lower heating wires (212,220) 5 to 10 seconds During heat welding.

상기 열융착 온도를 130℃ 미만의 온도로 할 경우, 플라스틱골판지(100)의 상·하부 판재(110,120)가 녹지 않아서 시간이 오래 걸릴 뿐 아니라 성형도 잘 되지 않는다. 게다가 눌러지는 압력으로 인해 플라스틱골판지(100)의 모양이 좋지 않게 되며 결국 파쇄되는 문제가 생긴다.When the thermal fusion temperature is less than 130 ° C, the upper and lower plate materials 110 and 120 of the plastic corrugated cardboard 100 do not melt, so it takes a long time and is not well formed. In addition, due to the pressure being pressed, the shape of the plastic corrugated cardboard 100 is not good and eventually causes a problem of being crushed.

또 열융착 온도를 150℃ 이상의 온도로 할 경우, 플라스틱골판지(100)의 상·하부 판재(110,120)가 빨리 녹기는 하지만 완전히 녹아버려서 모형이 나오지 않는다.In addition, when the heat-sealing temperature is 150 ℃ or more, the upper and lower plates 110, 120 of the plastic corrugated cardboard 100 melts quickly, but completely melts, and the model does not come out.

열융착 시간은 5초 미만으로 할 경우 완충공(140)이 막히지 않아 성형불량이 발생하며, 10초 이상으로 할 경우 플라스틱골판지(100)의 상·하부 판재(110,120)가 녹아버리게 된다.When the heat fusion time is less than 5 seconds, the molding holes are not blocked because the buffer hole 140 is not blocked, and when it is 10 seconds or more, the upper and lower plates 110 and 120 of the plastic corrugated cardboard 100 are melted.

따라서, 본 발명의 플라스틱골판지의 가장자리 봉합방법에서는 상·하부열선(212,220)에 의해 가열된 상부 융착면(230)과 하부 융착면(240)의 온도를 130∼150℃, 5∼10초 동안 적절히 조절하여 열융착시키는 것이 바람직하다. 다시 말하면, 플라스틱골판지가 두꺼운 경우에는 온도를 높이거나 시간을 길게 조절하고 플라스 틱골판지가 얇은 경우에는 온도를 낮게하거나 시간을 짧게 조절한다.Therefore, in the edge sealing method of the plastic corrugated cardboard of the present invention, the temperature of the upper fusion surface 230 and the lower fusion surface 240 heated by the upper and lower heating wires 212 and 220 is appropriate for 130 to 150 ° C. for 5 to 10 seconds. It is preferable to adjust and thermally fuse. In other words, if the plastic cardboard is thick, increase the temperature or lengthen the time, and if the plastic cardboard is thin, lower the temperature or shorten the time.

한편, 압력과 온도를 조절할 경우 압력을 높이고 온도를 낮게 하면 플라스틱골판지가 녹지 않은채 힘을 받게 되어 파손된다. 상기 파손된 부분은 백색으로 변하여 외관상 불량품이 되고 이 상태에서 더욱 압력이 높아지면 플라스틱골판지의 가장자리가 접합되지 않고 강제적으로 커팅된다.On the other hand, if pressure and temperature are adjusted, increasing the pressure and lowering the temperature will cause the plastic corrugated board to melt and be damaged. The damaged part turns white and becomes a defective product in appearance, and when the pressure becomes higher in this state, the edge of the plastic corrugated cardboard is forcibly cut without bonding.

그러므로, 본 발명의 플라스틱골판지의 가장자리 봉합방법에서는 압력을 일정하게 유지시키면서 온도를 높게 할 때 시간을 짧게 하고, 온도를 낮게 할 때 시간을 길게하는 식으로 온도와 시간 조건을 조절하는 것이 바람직하다.Therefore, in the edge sealing method of the plastic corrugated cardboard of the present invention, it is preferable to control the temperature and time conditions in such a manner that the time is shortened when the temperature is increased while the pressure is kept constant, and the time is increased when the temperature is lowered.

상기 열융착 단계를 후, 도 2d 및 도 2e에 나타낸 바와 같이, 상부 금형(210)을 상승시켜 플라스틱골판지(100)를 꺼낸 다음 표면이 용융상태인 플라스틱 골판지(100)의 상부 판재(110)와 하부 판재(120)의 가장자리, 즉 마감부(150)를 냉각시켜 열융착된 형상을 그대로 유지하게 한다.After the heat fusion step, as shown in Figures 2d and 2e, the upper mold 210 is raised to take out the plastic corrugated cardboard 100 and then the upper plate 110 of the plastic corrugated cardboard 100 is molten surface and The edge of the lower plate 120, that is, the finish 150 is cooled to maintain the heat-sealed shape.

마감부(150)가 냉각되면, 상기 마감부(150)의 외측으로 붙어있는 팁(160)을 제거하는데, 상기 마감부(150)와 팁(160)이 이어지는 부위에는 커팅홈(233)이 형성되어 약한 힘을 가해도 팁(160)이 쉽게 제거된다. 이렇게 팁(160)을 간단히 제거함으로써 본 발명의 봉합방법에 따른 가장자리가 봉합된 플라스틱골판지(100)가 완성된다.When the finish portion 150 is cooled, the tip 160 attached to the outside of the finish portion 150 is removed, and the cutting groove 233 is formed at a portion where the finish portion 150 and the tip 160 are continued. The tip 160 is easily removed even when a weak force is applied. By simply removing the tip 160, the plastic corrugated cardboard 100, which is edge-sealed according to the sealing method of the present invention, is completed.

상기와 같은 제작공정을 거친 플라스틱골판지(100)의 가장자리는 마감부(150)가 형성되어 제품의 보관이나 운송과정에서 가해지는 충격을 완충하기 위한 완충공(140)이 외부로 개방되지 않는다.The edge of the plastic corrugated cardboard 100 subjected to the manufacturing process as described above is the finishing portion 150 is formed is a buffer hole 140 for buffering the shock applied during the storage or transportation of the product is not opened to the outside.

따라서 먼지 등의 이물질이 플라스틱 골판지(100)의 내측으로 삽입되지 않게 되어 보관된 제품의 오염을 막아 제품의 상품성을 높일 수 있다.Therefore, foreign matters such as dust are not inserted into the plastic corrugated cardboard 100, thereby preventing contamination of the stored product, thereby increasing the productability of the product.
