본 고안은 보강사가 삽입된 환기 조절용 비닐하우스 필름의 제조장치에 관한 것으로 특히 필름제품 생산 공정중 컷터나이프형 장치를 개입시켜, 원통형 필름을 절단한 후 필름의 양단이 중첩되게 컷터나이프의 양단에 만곡부를 형성하고, 필름의 접합면에 보강용 노끈이나 연사를 삽입시키며 단부의 필름에 보강사 또는 접착제 또는 포편을 삽입하여 히팅의 가열 압착에 의하여 코팅 접착함으로서, 강도높은 합성수지 필름을 얻고자 하는 보강사가 삽입된 환기 조절용 비닐하우스 필름의 제조장치에 관한 것이다.The present invention relates to a manufacturing apparatus of a vinyl house film for ventilation control in which a reinforcement thread is inserted. Particularly, through a cutter knife-type device during a film product production process, after cutting a cylindrical film, curved portions are formed at both ends of the cutter knife so that both ends of the film overlap. The reinforcing yarn to obtain a high strength synthetic resin film by inserting a reinforcing braid or twisted yarn into the bonding surface of the film, and inserting a reinforcing yarn or adhesive or a piece of cloth into the film at the end and coating and bonding by heating and pressing. It relates to an apparatus for manufacturing a vinyl house film for ventilation control inserted.

종래의 합성수지 필름은 두께의 차이는 있으나 단일면으로 형성되어 있으므로 하우스 및 묘판의 피복제로 사용할 경우 바람이나 장력에 취약하여 찢어지는 폐단이 있어 주심스럽게 다루어져야 하는 불편이 있고, 이로 인하여 보온력이 상실될 뿐만아니라 경비부담이 과중한 실정이고, 또한 비교적 두꺼운 필름을 선택할 경우에는 빛의 투과율이 나쁘고, 제품의 값이 고가인 비경제적으로 단점이 있으며 하우스에 가해지는 중력이 과중하므로 식물의 재배에 매우부적합하였다.Conventional synthetic resin film has a difference in thickness, but is formed in a single side, so when used as a coating material for house and seedlings, there is a discomfort that must be handled with care because it is vulnerable to tearing due to wind or tension. In addition, the cost burden is excessive, and when a relatively thick film is selected, the light transmittance is poor, the product value is expensive, there is an economical disadvantage, and the gravity applied to the house is very unsuitable for plant cultivation. .

또한 연속적으로 인출되는 원통형 합성수지 필름을 수공에 의하여 짜개는 작업을 하게되므로 상당한 시간과 인력이 요구되어 비경제적인 문제가 있고 생산라인에서 별도의 절단기를 제작하여 설치해야 함으로 제작비와 설치비등의 소요가 막대한 비경제적인 폐단이 있었다.In addition, since the cylindrical synthetic resin film drawn out by hand is worked by hand, considerable time and manpower are required, which is uneconomical and requires a separate cutting machine to be manufactured and installed in the production line, which requires a great deal of production and installation costs. There was an uneconomic closure.

본 고안은 상기와 같은 문제점을 감안하여 해소하고자 안출한 것으로 필름제품 생산공정시 필름의 소정 위치를 째여지게 하고 합성수지 필름을 이중으로 중첩되게 접착하되, 접합면에 보강사인 노끈이나 연사를 삽입하여 하우스의 피복재로 사용할시에 인장력을 제공하게 되고, 자동적인 기계장치에 의하여 필름을 째여지게 하고, 이중으로 중첩되게 열접착시키는 과정을 보다 신속하고, 정확하게 함은 물론 안전성 면에서도 우수한 합성수지(PE, PVC, EVA등의)필름 절단장치 및 유도장치를 제공하고 강도높은 합성수지 필름을 얻고자 하는데 그 목적이 있다.The present invention has been devised to solve in view of the above problems, and the film is produced in the film production process to slit a predetermined position of the film, and the synthetic resin film is double-bonded to overlap each other. It provides tensile strength when used as a coating material, and makes the process of laminating the film by automatic mechanism and heat-bonding it to be overlapped twice more quickly, accurately, and in terms of safety. In order to provide a film cutting device and an induction device, such as EVA, and to obtain a high strength synthetic resin film.

이하 본 고안을 첨부 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 필름의 제조공정으로 압출기에서부터 전취부분 까지의 과정이다.1 is a process for producing a film from the extruder to the plunging portion.

수지물(1)을 압출실린더(2)에 삽입하면 동력에 의하여 실린더가 회전하여 수지가 히팅부다이(3)로 압입하게 된다.When the resin 1 is inserted into the extrusion cylinder 2, the cylinder is rotated by the power, and the resin is pressed into the heating die 3.

이때 공기주입구(4)로 공기를 불어 넣으면 맨드릴부(5)에서 수지가 팽창되어 블로우튜브(6)로 이송되고, 경사면에 다수의 가이드로울러(7)에 의하여 수지가 압축되어 러버닙로울러(8)와 닙로울러(9) 사이로 통과하여 가이드로울러(10)에 도달하면 컷터나이프와 보강사 삽입부, 히팅가열 압착부(11)에 의하여 보강사가 삽입된 합성수지 필름이 형성되어 가이드로울러(12)와 탠션콘트롤 로울러(13)에 의하여 와인더로울러(14)에 감기게 되는 구성으로 된다.At this time, when the air is blown into the air inlet (4), the resin is expanded in the mandrel part 5 is transferred to the blow tube (6), the resin is compressed by a plurality of guide rollers (7) on the inclined surface rubber nip roller (8) ) And the nip roller 9 to reach the guide roller 10 to form a synthetic resin film into which the reinforcement is inserted by the cutter knife, the reinforcement thread inserting portion, and the heating heating crimping portion 11 to form the guide roller 12 and The tension control roller 13 is configured to be wound around the winder roller 14.

이와 같이 구성된 본 고안의 작용 및 효과를 더욱 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above in more detail.

본 고안은 도면 제2도와 제3도 및 제4도에서와 같이 수지(1)를 압출하여 형성된 합성수지(PE, PVC, EVA등의) 필름(50)등을 가이드로울러(10)로 이송이 되면 컷터나이프(20)의 날부(20a)에서 필름(50)이 째여지고, 컷터나이프(20)의 양단으로 유입된다.The present invention is a synthetic resin (PE, PVC, EVA, etc.) film 50 formed by extruding the resin (1) as shown in Figure 2 and 3 and 4 when the transfer to the guide roller (10) The film 50 is slit from the blade portion 20a of the cutter knife 20 and flows into both ends of the cutter knife 20.

이때 컷터나이프(20)의 양단이 만곡형(20b)으로 형성되어 째여진 필름(50a)은 양단으로 접혀서 이중으로 중첩되어진다. 이때, 양측에 형성된 보강사 안내봉(30)으로 보강사(30a)인 노끈이나 연사를 인입시켜 이중으로 중첨된 필름(50a) 사이로 삽입시키고, 회전용보빈(60)에 감겨진 보강사(30a)도 인입시켜 컷터나이프(20)의 만곡형부(20a)를 통과한 필름(50a)은 로울러(40)에 형성된 히팅부(40a)의 가열 압착에 의하여 필름이 이중으로 중첩되어 지도록 한 것이다.At this time, both ends of the cutter knife 20 are formed in the curved shape 20b, and the film 50a, which is slanted, is folded at both ends and overlapped in duplicate. At this time, the reinforcement yarn guide rods 30 formed on both sides of the reinforcement yarn (30a) is introduced into the rope or twisted yarn is inserted between the double superimposed film (50a), the reinforcement yarn (30a) wound on the rotary bobbin 60 The film 50a, which has passed through the curved portion 20a of the cutter knife 20, is overlapped by a double layer by the heat pressing of the heating portion 40a formed in the roller 40.

다른 실시예도 제5도에서와 같이 보강사 안내봉(30)으로 보강사(30a)인 노끈이나 연사를 인입시켜 이중으로 중첩된 필름(50a) 사이로 삽입시키고 재봉기(80)장치에서 받침부(80a)와 노루발(80b)에서 필름을 잡아주면서 바늘(80c)에 보강사(30a)를 끼워서 재봉할 수도 있고 또한 로울러(40)에 형성된 히팅부(40a)의 압착에 의하여 필름을 이중으로 중첩할 수도 있다.Another embodiment is also inserted into the reinforcement yarn (30a) of the reinforcement yarn (30a), the braid or twisted yarn as shown in FIG. 5 inserted between the overlapping film (50a) and the support portion 80a in the sewing machine 80 device ) And the presser foot 80b may be sewn by inserting the reinforcement thread 30a into the needle 80c while the film is held by the presser foot 80b, or may overlap the film by pressing the heating part 40a formed on the roller 40. have.

또한 다른 실시예로 제6도에 도시한 바와 같이 보강사 안내봉(30)으로 보강사(30a)인 노끈이나 연사를 인입시켜 이중으로 중첩된 필림(50a) 사이로 접착제통(90)을 통과한 접착제(90a)를 삽입키고 히팅부(40a)의 압착에 의하여 필름을 이중으로 중첩할 수도 있다.In another embodiment, as shown in FIG. 6, a reinforcement yarn guide rod 30 is introduced into a reinforcement yarn 30a, a rope or a twisted yarn, and passes through the adhesive container 90 between the overlapping films 50a. The adhesive 90a may be inserted to overlap the film by pressing the heating part 40a.

더욱 견고하고 강도높은 합성수지 필름(50)을 얻고자 할 때에는 중첩된 필름(50a)의 단부에 보강사(30a)와 포편(70)을 삽입하고, 히팅부(40a)의 압착에 의하여 중첩되어 강도높은 합성수지 필름을 얻을 수 있다.In order to obtain a more robust and high strength synthetic resin film 50, the reinforcing yarn 30a and the piece 70 is inserted into the ends of the overlapped film 50a, and overlapped by the pressing of the heating part 40a to give strength. A high synthetic resin film can be obtained.

이러한 작용에 의하여 보강사가 삽입된 합성수지 필름은 텐션콘트롤 로울러를 거쳐서 와인더로울러(14)에 감겨지게 되는 것이다.By this action, the synthetic resin film into which the reinforcement yarn is inserted is wound on the winder roller 14 via the tension control roller.

이와 같이 본 고안은 수지를 발포시켜 합성수지 필름의 소정 위치를 슬리팅 컷터나이프로 절단시켜서 양단에 보강사를 삽입하여 필름을 중첩되게 가열 압착 또는 재봉기로 재봉접착, 합성수지 접착제를 도포한 접착을 함으로서 견고한 합성수지 필름을 얻을 수 있도록 하며 자동으로 대량생산하여 제품의 품질을 향상시킬 수 있는 이점이 있다.As such, the present invention is made by cutting a predetermined position of the synthetic resin film with a slitting cutter knife by inserting a reinforcement yarn at both ends by overlapping the film by heat pressing or sewing to overlap the film. There is an advantage to improve the quality of the product to obtain a synthetic film and to automatically mass production.
