도 1은 본 발명의 일 실시예에 따른 차량용 팩키지 트레이 제조방법을 보여주는 공정도이다. 도 2는 도 1에 도시된 차량용 팩키지 트레이 제조방법에 의하여 생산된 차량용 팩키지 트레이(100)를 보여주는 사시도이다. 1 is a process chart showing a vehicle package tray manufacturing method according to an embodiment of the present invention. 2 is a perspective view showing a vehicle package tray 100 produced by the vehicle package tray manufacturing method shown in FIG.

도 1 및 도 2를 참고하면, 차량용 패키지 트레이(100)의 제조방법은 하기와 같다. 1 and 2, the manufacturing method of the vehicle package tray 100 is as follows.

1. 재생PET수지(120) 형성 단계;1. forming a recycled PET resin 120;

사용자는 재생PET병을 수집할 수 있다. 이때, 재생PET병은 일반적인 음료수 용기일 수 있다. 재생PET병이 수집되면, 재생PET병을 분류한 후 분쇄하고 분쇄된 재생PET병을 세척하여 재생PET 플레이크(Flake)를 생성할 수 있다. 상기의 과정이 완료되면, 상기 재생PET 플레이크를 압출기를 통하여 펠릿화하고 열을 가하여 재생PET수지(120)를 생성시킬 수 있다. 이때, 필요에 따라 재생PET수지(120)에 각종 첨가제를 혼합하여 차량용 팩키지 트레이(100)의 필요한 물성을 조절할 수 있다.
The user can collect recycled PET bottles. At this time, the recycled PET bottle may be a general beverage container. Once the recycled PET bottle is collected, the recycled PET bottle can be sorted and pulverized and the pulverized recycled PET bottle can be washed to produce recycled PET flakes. When the above process is completed, the recycled PET flakes may be pelletized through an extruder and heated to generate a recycled PET resin 120. At this time, the necessary physical properties of the vehicle package tray 100 can be adjusted by mixing various additives in the recycled PET resin 120 as necessary.

2. 제 1 단계;2. first step;

상기의 과정이 완료되면, 원단을 준비할 수 있다. 이때, 원단(110)은 일반적인 차량용 내장재에 사용되는 부직포를 포함할 수 있다. 특히 원단(110)은 차량용 내장재에 사용되는 PET 부직포를 포함할 수 있다. When the above process is completed, the fabric can be prepared. In this case, the fabric 110 may include a nonwoven fabric used for a general vehicle interior. In particular, the fabric 110 may include a PET nonwoven fabric used for vehicle interiors.

원단(110)은 롤러 또는 컨베이어 밸트(1)에 의하여 이송될 수 있다. 이하에서는 설명의 편의를 위하여 원단(110)이 컨베이어 밸트(1)를 통하여 이송되는 경우를 중심으로 설명하기로 한다. The fabric 110 may be conveyed by a roller or a conveyor belt 1. Hereinafter, for convenience of description, the fabric 110 will be described based on a case where the conveyor belt 1 is transported.

한편, 원단(110)이 컨베이어 밸트(1)를 통하여 이동하는 동안, 스팀분사기(2)는 원단(110)의 일면에 스팀을 분사할 수 있다. 이때, 스팀분사기(2)에서 분사된 스팀은 원단(110)에 분사함으로써 재생PET수지(120)가 스며드는 것을 방지할 수 있다. 특히 스팀분사기(2)에서 분사된 스팀은 원단(110)에 스며들어 재생PET수지(120)가 원단(110)에 스며드는 것을 방지할 수 있다.
Meanwhile, while the fabric 110 moves through the conveyor belt 1, the steam injector 2 may inject steam to one surface of the fabric 110. In this case, the steam injected from the steam injector 2 may be prevented from infiltrating the recycled PET resin 120 by spraying the fabric 110. In particular, the steam injected from the steam injector 2 can be prevented from penetrating the fabric 110, the recycled PET resin 120 is penetrated to the fabric (110).

3. 제 2 단계;3. second step;

상기의 과정이 완료되면, 스팀이 분사된 원단(110)을 하부금형(3)에 안착시켜 적당한 크기로 클램핑(Clamping)할 수 있다. 이때, 하부금형(3)은 온유기(미도시)를 통하여 온도가 유지될 수 있다. 특히 하부금형(3)은 상기 온유기를 통하여 고온으로 유지될 수 있으며, 대략 100℃ 정도로 유지될 수 있다. When the above process is completed, it is possible to clamp the fabric (110) sprayed with steam to the lower mold (3) to a suitable size (Clamping). At this time, the lower mold 3 may be maintained in temperature through a warmer (not shown). In particular, the lower mold 3 may be maintained at a high temperature through the warmer, and may be maintained at about 100 ° C.

상기의 과정이 완료되면, 하부금형(3)에 안착된 원단(110) 상에 상부금형(4)을 위치시킬 수 있다. 이때, 상부금형(4)은 원단(110)의 일면으로부터 소정간격 이격되도록 배치될 수 있다.
When the above process is completed, the upper mold 4 can be placed on the fabric 110 seated on the lower mold (3). In this case, the upper mold 4 may be arranged to be spaced apart from one surface of the fabric 110 by a predetermined interval.

4. 제 3 단계;4. third step;

상기의 과정이 완료되면, 저압사출기(미도시)를 통하여 원단(110) 상에 재생PET수지(120)를 분사할 수 있다. 이때, 상기 저압사출기는 도 1의 상측에 배치되어 분사되고, 기존의 사출 성형과 달리 미소 형개 상태에서 재생PET수지(120)를 분사하므로 사출 압력을 기존보다 50~20%정도 낮춤으로서 원단(110)의 손상을 없애고, 원단(110)과 재생PET수지(120)의 접착/성형이 이루어질 수 있다.When the above process is completed, the recycled PET resin 120 may be sprayed onto the fabric 110 through a low pressure injection machine (not shown). At this time, the low-pressure injection machine is disposed and sprayed on the upper side of Figure 1, unlike the conventional injection molding, so as to spray the recycled PET resin 120 in a micro-opening state, lowering the injection pressure by 50 to 20% than conventional fabric 110 ), The fabric 110 may be bonded / molded with the recycled PET resin 120.

한편, 재생PET수지(120)를 사출한 후 상부금형(4)이 압착되어 원단(110) 상에 존재하는 재생PET수지(120) 표면에 허니콤 구조(130)를 형성할 수 있다. 이때, 상부금형(4)의 일면에는 허니콤 구조(130)와 대응되도록 허니콤 구조(130)가 형성될 수 있다. Meanwhile, the honeycomb structure 130 may be formed on the surface of the recycled PET resin 120 existing on the fabric 110 by pressing the upper mold 4 after injecting the recycled PET resin 120. In this case, the honeycomb structure 130 may be formed on one surface of the upper mold 4 so as to correspond to the honeycomb structure 130.

따라서 재생PET수지(120) 표면에 형성되는 허니콤 구조(130)에 의하여 제품의 강성을 확복할 수 있다. Therefore, the honeycomb structure 130 formed on the surface of the recycled PET resin 120 can expand the rigidity of the product.

한편, 상기의 과정이 완료되면, 재생PET수지(120)가 도포된 원단(110)을 취출하여 냉각시켜 차량용 팩키지 트레이(100)를 완성시킬 수 있다.
On the other hand, when the above process is completed, taking out and cooling the fabric 110 coated with the recycled PET resin 120 may complete the vehicle package tray 100.

5. 제 4 단계;5. fourth step;

상기의 과정이 완료되면, 차량용 팩키지 트레이(100)를 재결정화 장치(5)의 내부에 배치시킬 수 있다. 이때, 차량용 팩키지 트레이(100)는 재결정화 장치(5) 내부에서 재결정화가 될 수 있다. 구체적으로 차량용 팩키지 트레이(100)의 재생PET수지(120)는 재결정화 장치(5)의 내부에서 재생PET수지(120)의 플라스틱 사슬구조가 재결정화될 수 있다. When the above process is completed, the vehicle package tray 100 may be disposed in the recrystallization apparatus 5. In this case, the vehicle package tray 100 may be recrystallized in the recrystallization apparatus 5. Specifically, the recycled PET resin 120 of the vehicle package tray 100 may recrystallize the plastic chain structure of the recycled PET resin 120 inside the recrystallization apparatus 5.

한편, 상기와 같이 진행되는 동안 재결정화 장치(5)는 내부의 온도를 100℃ 이상 200℃ 이하로 유지시킬 수 있다. 이때, 재결정화 장치(5)의 내부의 온도가 100℃ 미만인 경우 재생PET수지(120)의 플라스틱 사슬구조가 제대로 형성되지 않아 차량용 팩키지 트레이(100)의 강성이 작아질 수 있다. 또한, 재결정화 장치(5)의 내부의 온도가 200℃를 초과하는 경우 재생PET수지(120)가 녹아 차량용 팩키지 트레이(100)의 형상이 가변하거나 강성의 문제가 발생할 수 있다. On the other hand, the recrystallization apparatus 5 can maintain the internal temperature at 100 ° C or more and 200 ° C or less while the above progresses. In this case, when the temperature inside the recrystallization apparatus 5 is less than 100 ° C., the plastic chain structure of the recycled PET resin 120 may not be properly formed, thereby reducing the rigidity of the vehicle package tray 100. In addition, when the temperature inside the recrystallization apparatus 5 exceeds 200 ° C., the recycled PET resin 120 may be melted to change the shape of the vehicle package tray 100 or may cause rigidity problems.

차량용 팩키지 트레이(100)는 상기와 같은 온도 조건에서 재결정화 장치(5) 내부에 2시간 이상 3 시간 이하 동안 배치될 수 있다. 이때, 2시간 미만 동안 이나 3시간을 초과하여 배치되는 경우, 상기에서 설명한 바와 같이 차량용 내장재에 필요한 강성을 확보할 수 없다. The vehicle package tray 100 may be disposed in the recrystallization apparatus 5 for 2 hours or more and 3 hours or less under the above temperature conditions.
