Description

TPU­PTFE접합필름의 제조장치{Apparatus Of Manufacturing TPU­PTFE Bonding Film}Manufacturing apparatus of TPUPTFE bonding film {Apparatus Of Manufacturing TPUPTFE Bonding Film}

본 발명은 반도체 및 디스플레이산업등에 사용되는 전선 케이블 POD용 필름을 제조하기 위해 TPU를 압출과 동시에 PTFE필름에 접합하는 장치에 관한 것이다.The present invention relates to a device for extruding TPU and simultaneously bonding it to a PTFE film in order to manufacture a film for wire cable POD used in the semiconductor and display industries.

종래의 압출 장치는 종이제조장비, 인쇄 및 포장장비에 일반적으로 사용되는 종이, 필름, 부직포, 알루미늄 호일, 미카 테이프 및 기타 얇은 재료의 대형 t-die를 이용하여 압출하고 필름화하여 이를 합지하는 공정에서 접합하여 각종 포장재, 산업용 및 농업용에 사용되고 있다. 하지만, 이러한 장비는 각 공정이 따로따로 구성되어 있고 공정별 제작방법이 다르게 하고 있다. Conventional extrusion equipment uses a large t-die of paper, film, non-woven fabric, aluminum foil, mica tape and other thin materials commonly used in paper manufacturing equipment, printing and packaging equipment to extrude, film, and laminate them. It is used for various packaging materials, industrial and agricultural purposes. However, these equipments are configured for each process separately, and the manufacturing method for each process is different.

한편, PTFE는 높은 내약품성, 낮은 유전율 등의 특성을 가지며, 융점이 높고 내열성 및 내약품성이 우수하기 때문에, 제품의 특성상 카렌다로 압출시켜 필름형태로 가공하여 OLED 공정장비부품, 반도체 장비부품, 산업용가스켓, 점착·전기절연테이프등의 화학 및 전기 케이블 분야를 중심으로 폭 넓은 용도로 사용되고 있다.On the other hand, PTFE has characteristics such as high chemical resistance and low permittivity, and has a high melting point and excellent heat resistance and chemical resistance. It is used for a wide range of purposes, mainly in the field of chemical and electric cables such as gaskets, adhesive and electrical insulating tapes.

이러한 PTFE필름은 필름의 길이방향으로는 1차 연신을 하여 제조되므로 길이방향으로는 연신이 잘되지 않지만 폭방향으로는 연신이 잘되는 성질을 가진다. 일반적으로 TPU와 접합시 PTFE 필름과 TPU필름을 따로 제조하고 이것을 합지 공정에서 다시 접합하는 공정을 거친다. 하지만 상기 기존 장치로 합지시 PTFE필름이 폭방향으로 연신되어 밀리거나 주름으로 인하여 균일한 품질유지가 어려웠으며, 특히 TPU 표면이 일정하게 매끄럽지가 못하여 표면에 굴곡이 생기고 이러한 단차로 인하여 pod생산시 접착강도의 불균형과 두께단차로 인하여 제품의 꼬임이 발생하는 문제점이 발생하였다. Since such a PTFE film is prepared by primary stretching in the longitudinal direction of the film, it does not stretch well in the longitudinal direction, but has a property of being well stretched in the width direction. In general, when bonding with TPU, a PTFE film and a TPU film are separately manufactured and bonded again in a laminating process. However, when laminating with the existing device, the PTFE film was stretched in the width direction, and it was difficult to maintain uniform quality due to pushing or wrinkles. There was a problem that twisting of the product occurred due to the imbalance of strength and the difference in thickness.

대한민국특허공개제10-2017-0012055호(2017년02월02일 공개)Korean Patent Publication No. 10-2017-0012055 (published on February 2, 2017)

따라서 본원발명에서는 PTFE필름와 압출 TPU의 접합을 위하여 장치폭방향으로는 연신이 잘되는 성질을 가지는 PTFE필름이 폭방향으로 연신되어 밀리거나 주름이 발생하는 것을 방지함으로써 균일하게 TPU의 접착을 이룰수 있고, 기존의 문제점인 필름의 두께편차 및 특정부위의 주름을 방지하여 균일한 품질의 압출접합필름 제공하는 것을 기술적과제로 한다. Therefore, in the present invention, for the bonding of the PTFE film and the extruded TPU, the PTFE film, which has a property of being well stretched in the device width direction, is stretched in the width direction to prevent pushing or wrinkles, so that the TPU film can be bonded uniformly. It is a technical task to provide an extrusion bonding film of uniform quality by preventing film thickness deviation and wrinkles in a specific area, which are problems of.

도 1에 도시된 것과 같이, 본 발명의 일 실시예에 의한 TPU­PTFE접합필름의 제조장치는 PTFE필름을 공급하는 공급롤러부; 공급가이드롤러부; 텐션롤러부; TPU압출기; 상·하부롤러부; 제1압입롤러부; 칠러롤러부; 제2압입롤러부; 와인더부로 이루어진다. As shown in Figure 1, the apparatus for manufacturing a TPUPTFE bonding film according to an embodiment of the present invention includes a supply roller unit for supplying a PTFE film; Supply guide roller unit; Tension roller unit; TPU extruder; Upper and lower roller parts; a first press roller unit; chiller roller unit; a second press roller unit; It consists of a winder part.

공급롤러부(100)는 PTFE필름(1)을 접합장치로 공급하는 것으로서 필름이 일정한 토크로 풀리도록 한다. The supply roller unit 100 supplies the PTFE film 1 to the bonding device and unwinds the film with a constant torque.

공급가이드롤러부(200)는 상기 공급롤러부(100)로부터 공급되는 PTFE필름의 텐션을 고르게 하고 일률적으로 펴지도록 하는 것으로서 도 2에 도시된 바와 같이 2이상의 공급가이드롤러(20), 슬라이딩바(21), 및 롤러지지부재(22)로 구성된다. 도 2에 도시된 바와 같이 슬라이딩바(21)에 의해 필름을 정렬하며 일정한 장력을 유지시키고 펴질 수 있게 할 수 있다.The supply guide roller unit 200 evenly and evenly spreads the tension of the PTFE film supplied from the supply roller unit 100, and as shown in FIG. 2, two or more supply guide rollers 20, a sliding bar ( 21), and a roller support member 22. As shown in FIG. 2 , the film may be aligned by the sliding bar 21 , and a constant tension may be maintained and stretched.

텐션롤러부(300)는 상기 공급롤러부로부터 공급되는 PTFE필름의 폭조절 및 장력부여를 하는 상,하로 이루어진 텐션롤러(30)로 구성되어 PTFE필름의 이송방향에 대해 45~90°각도로 서로 대칭되도록 필름의 변부쪽의 양측단에 한쌍씩 형성된다.The tension roller unit 300 consists of upper and lower tension rollers 30 that adjust the width and give tension to the PTFE film supplied from the supply roller unit, and are mutually at an angle of 45 to 90 ° with respect to the transport direction of the PTFE film. One pair is formed at both ends of the edge side of the film so as to be symmetrical.

상기 텐션롤러부(300)는 도 3a에 도시된 바와 같이 모터(31)와 연동되어 있으며, 상,하로 이루어진 한쌍의 텐션롤러(30)가 PTFE필름의 이송방향에 대해 45~90°각도로 서로 대칭되도록 양측단에 형성되어 폭방향으로 필름을 변부쪽으로 밀어줌으로써 필름이 안쪽으로 쏠리는 것을 방지할 수 있다. As shown in FIG. 3A, the tension roller unit 300 is interlocked with the motor 31, and a pair of upper and lower tension rollers 30 are connected to each other at an angle of 45 to 90 ° with respect to the transport direction of the PTFE film. It is formed at both ends so as to be symmetrical, and by pushing the film toward the edge in the width direction, it is possible to prevent the film from leaning inward.

본 발명의 접합대상인 PTFE필름은 필름의 이송방향으로는 이미 1차 연신이 된 부분이라 연신이 잘되지 않지만 폭방향으로는 연신이 잘되는 필름으로서 통상적인 롤러의 조합으로는 필름폭방향으로 연신이 발생하여 슬릿시 세폭필름의 폭이 균일하지 못하는 문제점이 발생할 수 있다. 따라서 본 발명에서는 상기 텐션롤러부(300)에 의해 PTFE필름의 변부쪽을 견고히 고정시킬 수 있도록 하는 것이다.The PTFE film, which is the bonding target of the present invention, is not well stretched in the film transport direction because it has already been first stretched, but it is well stretched in the width direction. As a result, a problem in that the width of the thin film is not uniform during slitting may occur. Therefore, in the present invention, the edge side of the PTFE film can be firmly fixed by the tension roller unit 300.

상기 텐션롤러부(300)는 도 3a,3b에 도시된 바와 같이 상,하로 이루어진 한쌍의 롤러를 서로 대칭되도록 양측단에 설치하여 상기 텐션롤러를 45~90°까지 각도를 조절하여 필름의 종류 및 필름 폭에 따라 PTFE필름에 장력을 부여하도록 한다.As shown in FIGS. 3A and 3B, the tension roller unit 300 installs a pair of upper and lower rollers at both ends so as to be symmetrical with each other, and adjusts the angle of the tension rollers from 45 to 90 ° to determine the type of film and Apply tension to the PTFE film according to the film width.

PTFE필름은 일반적인 pp필름 또는 pe필름등과 달리 정전기가 많이 발생하고 필름 양단 끝부분에서 폭방향으로 고무줄처럼 늘어지는 경향이 있어 두께주름이 발생하기 쉽다. 따라서 PTFE필름의 두께에 따라 주름이 발생하지 않도록 장력을 주고 45~90°까지 각도를 조절하여 폭주름을 최소화하여야 TPU접합시 필름의 밀림이나 주름부분이 발생되지 않는다.Unlike general pp film or pe film, PTFE film generates a lot of static electricity and tends to stretch like a rubber band in the width direction at both ends of the film, so thickness wrinkles are likely to occur. Therefore, depending on the thickness of the PTFE film, tension should be applied so that wrinkles do not occur, and the angle should be adjusted from 45 to 90 ° to minimize width wrinkles so that the TPU film does not push or wrinkle when bonding.

특히, 도 4에 도시된 바와 같이 상기 텐션롤러부의 상기 롤러의 외주에는 요홈(32)이 형성되어 PTFE필름의 고정을 보다 확실하게 함으로써 필름의 밀림이나 주름부분이 발생되지 않도록 할 수 있어 바람직하다. 상기 텐션롤러부는 금속재로 이루어질 수도 있으며, 필름의 지지를 보다 확실히 하기 위해 롤러표면이 실리콘, 우레탄, RTV등의 합성수지재로 형성될 수도 있다.In particular, as shown in FIG. 4, a concave groove 32 is formed on the outer circumference of the roller of the tension roller part to ensure the fixation of the PTFE film, thereby preventing the film from being pushed or wrinkled. The tension roller part may be made of a metal material, and the surface of the roller may be formed of a synthetic resin material such as silicon, urethane, or RTV to more surely support the film.

TPU압출기(400)는 이송되는 PTFE필름의 표면에 TPU를 도포하기 위해 TPU를 T다이를 통해 압출하는 것으로서 후술할 상부롤러와 하부롤러의 사이에 T다이가 형성되어 이송되는 PTFE필름의 표면에 TPU를 도포하게 된다. 경우에 따라서는 T-DIE가 상방 또는 하방에서 도포될 수도 있는데, 이경우 상기 상부롤러와 하부롤러의 위치도 변경을 할 수 있다. 상기 TPU압출기는 통상의 압출기를 사용할 수 있다.The TPU extruder 400 extrudes TPU through a T-die to apply TPU on the surface of the transferred PTFE film, and a T-die is formed between an upper roller and a lower roller to be described later to form TPU on the surface of the transferred PTFE film. will spread In some cases, T-DIE may be applied from the top or bottom, and in this case, the positions of the upper and lower rollers may also be changed. As the TPU extruder, a conventional extruder may be used.

상·하부롤러부(500)는 상기 TPU가 도포된 TPU­PTFE접합필름(2)을 가압하면서 이송하는 롤러로서 PTFE필름의 표면에 도포된 TPU를 PTFE필름에 밀착시키기 위하여 일정한 압력으로 눌러 접합하게 된다. 상·하부롤러부(500)의 재질은 일반 금속재일 수도 있고, 접합의 균일화를 위하여 롤러표면이 실리콘, 우레탄, RTV등 합성 수지재로 형성될 수도 있다. 이때 상·하부롤러부의 압력은 3~7 BAR 범위에서 유지될 수 있고 일률적인 두께 형성을 위하여 두께를 고정시켜 놓고 밀착시킬 수도 있다.The upper and lower roller parts 500 are rollers that pressurize and transfer the TPU-coated TPUPTFE bonding film 2, and press and bond the TPU applied on the surface of the PTFE film with a constant pressure to adhere it to the PTFE film. The material of the upper and lower roller portions 500 may be a general metal material, and the surface of the roller may be formed of a synthetic resin material such as silicon, urethane, or RTV for uniform bonding. At this time, the pressure of the upper and lower rollers can be maintained in the range of 3 to 7 BAR, and the thickness can be fixed and adhered to form a uniform thickness.

제1압입롤러부(600)는 상기 하부롤러와 접하도록 형성된 롤러로서 PTFE필름의 표면에 도포된 TPU를 PTFE필름에 보다 밀착시키는 작용을 한다. 칠러롤러부(700)는 상기 제1압입롤러부를 통과하는 TPU­PTFE접합필름의 TPU를 냉각하는 것으로서 롤러내부로 냉각수를 통과시켜 냉각시키도록 한다.The first press roller unit 600 is a roller formed to come into contact with the lower roller, and serves to bring the TPU coated on the surface of the PTFE film into closer contact with the PTFE film. The chiller roller part 700 cools the TPU of the TPUPTFE bonding film passing through the first press roller part, and cools it by passing cooling water into the roller.

제2압입롤러부(800)는 상기 칠러롤러부와 접하도록 형성된 것으로서 PTFE필름의 표면에 도포된 TPU를 PTFE필름에 보다 밀착시키는 작용을 한다. 와인더부(900)는 상기 칠러롤러부로부터 송출되는 TPU­PTFE접합필름(2)을 권취하는 것이다.The second press roller unit 800 is formed to come into contact with the chiller roller unit and serves to bring the TPU coated on the surface of the PTFE film into closer contact with the PTFE film. The winder unit 900 winds the TPUPTFE bonding film 2 sent from the chiller roller unit.

이하에서는 본 발명의 TPU­PTFE접합필름의 제조장치를 이용한 TPU­PTFE접합공정에 대하여 설명하기로 한다. 도 1에 도시된 바와 같이 공급롤러부(100)에 감긴 PTFE필름(1)은 일정한 토크로 풀리도록 하여 공급가이드롤러부(200)로 공급된다. 상기 공급롤러부(100)에 의해 공급되는 PTFE필름을 정렬하며 일정한 장력을 유지시키고 펴질 수 있게 할 수 있다.Hereinafter, the TPUPTFE bonding process using the apparatus for manufacturing the TPUPTFE bonding film of the present invention will be described. As shown in FIG. 1 , the PTFE film 1 wound around the supplying roller unit 100 is supplied to the supplying guide roller unit 200 while being unwound at a constant torque. It is possible to align the PTFE film supplied by the supply roller unit 100, maintain a constant tension, and allow it to be stretched.

이후 PTFE필름(1)은 필름의 이송방향에 대해 45~90°각도로 서로 대칭되도록 필름의 변부쪽의 양측단에 한쌍씩 형성된 텐션롤러부(300)를 통과하면서 PTFE필름의 장력이 부여되어 필름폭방향으로 필름을 변부쪽으로 밀어주면서 필름을 통과시켜 필름이 안쪽으로 쏠리는 것을 방지한다. PTFE필름의 두께에 따라 주름이 발생하지 않도록 장력을 주고 45~90°까지 각도를 조절하여 폭주름을 최소화하여야 TPU접합시 필름의 밀림이나 주름부분이 발생되지 않는다.Thereafter, the PTFE film (1) passes through the tension roller units 300 formed in pairs at both ends of the edge side of the film so that they are symmetrical to each other at an angle of 45 to 90 ° with respect to the transport direction of the film, and tension of the PTFE film is applied to the film. While pushing the film toward the edge in the width direction, the film passes through the film to prevent the film from leaning inward. Depending on the thickness of the PTFE film, give tension to prevent wrinkles and adjust the angle from 45 to 90° to minimize width wrinkles so that the film does not slide or wrinkles occur during TPU bonding.

이후 PTFE필름은 상·하부롤러부(500)를 통과하면서 TPU가 도포된다. TPU압출기(400)의 T다이를 통해 TPU가 압출되며, 상기 상·하부롤러부(500)사이에 T다이를 위치하도록 하여 이송되는 PTFE필름의 표면에 TPU를 도포하게 된다. 경우에 따라서는 T-DIE의 위치에 따라 TPU가 상·하부롤러부의 상방 또는 하방으로 도포될 수도 있는데, 이 경우 상기 상부롤러와 하부롤러의 위치도 변경을 할 수 있다. 상기 TPU압출기는 통상의 압출기를 사용할 수 있다. TPU와 PTFE필름의 접합시 온도는 170~200℃에서 접합하는 것이 좋다. Afterwards, TPU is applied to the PTFE film while passing through the upper and lower roller portions 500. TPU is extruded through the T-die of the TPU extruder 400, and the T-die is placed between the upper and lower roller parts 500 to apply the TPU to the surface of the transferred PTFE film. In some cases, TPU may be applied to the top or bottom of the upper and lower rollers depending on the position of the T-DIE. In this case, the positions of the upper and lower rollers may also be changed. As the TPU extruder, a conventional extruder may be used. When bonding TPU and PTFE films, it is recommended to bond at a temperature of 170~200℃.

이때 상·하부롤러부(500)는 상기 TPU가 도포된 TPU­PTFE접합필름(2)을 가압하면서 이송하는데, PTFE필름의 표면에 도포된 TPU를 PTFE필름에 밀착시키기 위하여 일정한 압력으로 눌러 접합하게 된다. 상·하부롤러부의 압력은 3~7 BAR 범위에서 유지될 수 있고 일률적인 두께 형성을 위하여 두께를 고정시켜 놓고 밀착시킬 수도 있다.At this time, the upper and lower rollers 500 transfer while pressurizing the TPU-PTFE bonding film 2 coated with the TPU, and presses and bonds the TPU coated on the surface of the PTFE film with a constant pressure to adhere it to the PTFE film. The pressure of the upper and lower rollers can be maintained in the range of 3 to 7 BAR, and the thickness can be fixed and adhered to form a uniform thickness.

상기 하부롤러와 접하도록 형성된 롤러인 제1압입롤러부(600)에 의해 PTFE필름의 표면에 도포된 TPU를 PTFE필름에 보다 밀착시키며, 상기 제1압입롤러부를 통과하는 TPU­PTFE접합필름의 TPU를 냉각하여 안정화하기 위해 칠러롤러부(700)에 접하도록 통과시킨다. 이때 상기 칠러롤러부와 접하도록 형성된 제2압입롤러부(800)에 의해 PTFE필름의 표면에 도포된 TPU를 PTFE필름에 보다 밀착시킨다. 상기 칠러롤러부로부터 송출되는 TPU­PTFE접합필름(2)을 와인더부(900)에 권취하여 TPU­PTFE접합필름을 제조하게 된다.The TPU applied to the surface of the PTFE film is brought into close contact with the PTFE film by the first press roller unit 600, which is a roller formed to come into contact with the lower roller, and cools the TPU of the TPU PTFE bonding film passing through the first press roller unit. so as to be in contact with the chiller roller unit 700 for stabilization. At this time, the TPU coated on the surface of the PTFE film is brought into close contact with the PTFE film by the second press roller unit 800 formed to come into contact with the chiller roller unit. The TPUPTFE bonding film 2 sent from the chiller roller unit is wound around the winder unit 900 to manufacture a TPUPTFE bonding film.
