본 발명은 합성수지 필름을 연신함에 있어 매우 간단한 구조로서 압출기의 T다이로부터 용융되어 나오는 미연신 필름을 종, 횡 방향으로 동시에 연신하므로서 연신장치의 간소화와 제작원가의 절감을 가하고자 안출한 필름의 종, 횡 동시 연신장치에 관한 것이다.The present invention is a very simple structure in the stretching of the synthetic resin film, the unstretched film melted from the T-die of the extruder in the longitudinal, transverse direction at the same time to extend the simplification of the stretching device and to reduce the production cost And a transverse simultaneous stretching apparatus.

종래의 필름 연신방법은 성형로울러의 후방에 종방향 연신장치와 횡방향 연신장치를 각각 설치하여서 성형로울러에 의해 냉각된 미숙성 상태의 용융필름을 종방향과 횡방향으로 순차 연신하는 방법을 사용하고 있는 바 일반적으로 성형로울러의 직후방에 종방향 연신장치를 설치하여 먼저 종방향으로 연신을 시킨다음 크립등을 사용하여 횡방향으로 연신하고 있으나 종방향으로 연신할때는 로울러에 의해 실시하므로 작업이 간단하나 횡방향으로 연신할때는 크립등으로 잡아당겨 연신함에 따라 균일하게 연신이 불가능하고 연신작업시 찢어지는 폐단이 있다.The conventional film stretching method uses a longitudinal stretching device and a transverse stretching device respectively installed at the rear of the molding roller to sequentially stretch the immature molten film cooled by the molding roller in the longitudinal and transverse directions. In general, the longitudinal stretching device is installed immediately after the forming roller, and the drawing is carried out in the longitudinal direction first, and then the drawing is done in the transverse direction using a creep, etc. When stretching in the lateral direction, it is impossible to stretch uniformly by pulling with a creep or the like, and there is a closed end that is torn during stretching.

따라서 최근에는 카터필터를 이용하여 횡방향으로 연신한후 다시 종방향으로 연신하는 장치가 안출되어 공고된바 있다. 그러나 이들은 모드 종방향과 횡방향 연신장치를 각각 설치하여야 되는 점에서 동일하여 설치비가 엄청나게 많이 소요되고 이로인해 제작단가가 고가인 폐단이 있었고 복잡한 구조로서 대형화되어 설치장소를 많이 차지할뿐 아니라 필름 제작시간 또한 많이 소요되는 등 여러가지 폐단이 있었다.Therefore, recently, an apparatus for stretching in the lateral direction after stretching in the lateral direction using the Carter filter has been proposed and announced. However, these are the same in that the mode longitudinal and transverse stretching devices must be installed separately, which requires a great deal of installation cost, and there is a closed end which is expensive to manufacture. There were also various closures, including a lot of consumption.

본 발명은 이와 같이 점을 감안하여 안출한 것으로 미연신 상태의 필름을 타력에 의해서 회전되는 회전공을 이용하여 종, 횡으로 동시 연신을 가능하게 하므로서 종래의 결점을 일소한 것인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been devised in view of the above point, and by using a rotating hole rotated by the inerting force of the film in the unstretched state, it is possible to simultaneously stretch longitudinally and laterally, thus eliminating the conventional drawbacks based on the accompanying drawings. The above is as follows.

T 다이(1)의 전방에 냉각 성형로울러(2)와 인취로울러(3)를 순차적으로 설치한 통상의 필름연신장치에 있어서 인취로울러(3)의 전방에 테프론(4)을 코팅한 회전공(5)을 지축(6)에 회전가능하도록 축설하고 그 전방에 양단을 회전공(5)의 곡면과 동일하게 형성한 양귀연신로울러(7)와 연전로울러(8)를 순서적으로 접면 설치하여서 되는 것이다.In a conventional film stretching apparatus in which a cooling forming roller 2 and a take-out roller 3 are sequentially installed in front of the T die 1, a rotary ball coated with Teflon 4 in front of the take-out roller 3 ( 5) is arranged so as to be rotatable on the support shaft 6, and the front and rear extension rollers 7 and the extension rollers 8, both ends of which are formed in the same direction as the curved surface of the rotary hole 5, are folded in order. will be.

도면중 미설명부호 9는 필름이고 10은 텐터이며 11은 인취로울러이고 12는 제품이다. 이와 같이된 본 발명은 압출기로부터 용융된 용융수지가 T다이(1)에 의해 판상으로 압출되어 나오면 그 전방에 설치된 냉각 성형로울러(2)로서 미숙성상태로 냉각되어 인취로울러(3)의 인장력에 의해 종방향으로 연신되면서 계속 전방으로 송급되어진다. 이와 같이 종방향으로 연신되면서 송급되는 미숙성상태의 미연신필름은 인취로울러(3)의 전방에 축설된 회전공(5)의 상면에 접면상태로 통과하여 양귀연신로울러(7)와의 사이를 거친후 연전로울러(8)를 통과하게 되는바 이때 미숙성상태의 필름이 인취로울러(3)를 거친후 회전공(5)을 통과할때 필름은 테프론(4)이 코팅된 회전공(5)의 곡면에 의해 사방으로 미끄러지면서 첨부도면 제2도와 같이 종, 횡방향으로 연신되어지게 된다.In the figure, reference numeral 9 is a film, 10 is a tenter, 11 is a drawer, and 12 is a product. According to the present invention as described above, when the molten resin melted from the extruder is extruded into a plate by the T die 1, it is cooled to an immature state as a cooling forming roller 2 installed in front of it, and thus the tensile force of the take-out roller 3 is reduced. It is stretched in the longitudinal direction, and is continuously fed forward. The unstretched film in the immature state, which is stretched and fed in the longitudinal direction, passes through the upper surface of the rotary hole 5 arranged in front of the take-out roller 3 in a state of contact and passes through the both-side stretching roller 7. After passing through the rolling roller (8), when the immature film passes through the take-out roller (3) and passes through the rotating hole (5), the film of the rotating hole (5) coated with Teflon (4) The surface is slid in all directions while being stretched in the longitudinal and transverse directions as shown in FIG. 2.

그러나 이때 연신된 필름은 곡면에 의해 미끄러지면서 연신된 것이므로 종래 양측에서 당기는 것보다 팽팽하지 않고 또한 양측부는 완전히 연신되지 못하는 점이 있으나 이것은 다시 회전공(5)과 접면된 상태로 축설된 양귀 연신로울러(7)를 거쳐 나가는 동안 필름의 양귀가 양귀연신로울러(7)에 의해 팽팽한 상태로 연신되어져 전술한 바와 같은 문제점은 해소되며 나아가서 이와 같은 상태로 연신되어 나온 필름은 다음의 연신로울러(8)에 의해 완전히 팽팽한 상태로 연전되어 다음 공정인 덴터의 인취로울러 및 냉각로울러를 거쳐 숙성되고 냉각되므로서 완전히 연신된 필름이 완성되는 것이다.However, at this time, the stretched film is stretched while being slid by a curved surface, so that the stretched film is not taut than conventional pulls on both sides, and both sides are not fully stretched. 7) Both ears of the film are stretched in the tensioned state by the both ears stretching roller 7 while going out through the above, and the above-mentioned problem is solved. Furthermore, the film drawn in such a state is drawn by the following stretching roller 8. The stretched film is stretched completely and is matured and cooled through the take-out roller and the cooling roller of the next process, which is a complete stretched film.

이상과 같은 작용을 간단히 요약하면 미숙성 상태로 송급되는 필름(9)이 인취로울러(3)(11) 및 기타 각 로울러에 의거 인장상태로 이동되어 종방향으로 연신되면서 테프론(4)을 코팅한 회전공(5)에 의거 종, 횡방향으로 사방 연신되고 이와 같이 1차 종, 횡방향으로 연신된 필름은 양귀연신로울러(7)에 의거 2차적으로 완전히 연신되어진후 연전로울러(8)로서 팽팽히 퍼져 다음의 일반적인 공정에 의거 종, 횡방향으로 동시에 연신된 필름이 제작되는 것이다. 이와 같이 본 발명은 회전공(5)으로서 필름(9)을 종, 횡방향으로 동시에 연신하게 되므로 필름연신작업이 매우 간단하고 필름 제작이 용이하며 간단한 구조로서 설치비용 또한 저렴할뿐 아니라 설치장소를 적게 차지하는 등 그 효과가 매우 크다.Briefly summarizing the above operation, the film (9) fed in the immature state is moved to the tension state by the take-out roller (3) (11) and other rollers and stretched in the longitudinal direction to coat the Teflon (4). The film stretched in all directions in the longitudinal and transverse directions on the basis of the rotary hole 5 and thus stretched in the primary and transverse directions in this manner is stretched secondarily by the double-ear stretching rollers 7 and then stretched as the extension rollers 8. By spreading, a film drawn simultaneously in the longitudinal and transverse directions is produced according to the following general process. As described above, the present invention extends the film 9 simultaneously in the longitudinal and transverse directions as the rotary hole 5, so that the film stretching operation is very simple, the film is easy to manufacture, and the simple structure is low in installation cost and the installation place is small. The effect is very big.
