Abstract
Description
제1도는 본 발명에 의하여 제조된 카메라케이스의 사시도1 is a perspective view of a camera case manufactured according to the present invention
본 발명은, 부식포 및 필름, P.U(폴리우레탄)가 순차 접착된 인조피혁을 이용한 각종 케이스, 즉 카메라나 가방등을 압축프레스로 열처리 가공하여 봉제선이 극히 배제되고 외관이 미려하며, 제작공정의 단축 및 인력의 절감과 대량생산이 용이하도록 한 인조피혁을 이용한 케이스의 제조방법에 관한 것이다.The present invention heat-treats various cases using an artificial leather, in which a corrugated cloth, a film, and PU (polyurethane) are sequentially bonded to each other, such as a camera or a bag, using a compression press to exclude seams and have a beautiful appearance. The present invention relates to a method for manufacturing a case using artificial leather, which allows for shortening, reduction of manpower, and mass production.
상기 인조피혁은, 부식포의 상면에 은총(접착층)을 형성하고 필름을 피착하여 표면을 고르게 한후 P.U로 도포한 것으로 일명 습식 P.U라고도 하며, 융해 온도가 통상 130℃-150℃로서 150℃이상일 경우 적정시간(약 20초 정도)이 지나면 융해되는 재질상의 특징이 있다.The artificial leather is formed on the upper surface of the corroded cloth (adhesive layer), the film is deposited, the surface is evenly applied and then coated with PU, also known as wet PU, when the melting temperature is usually 130 ℃ -150 ℃, 150 ℃ or more There is a material characteristic that melts after a suitable time (about 20 seconds).
따라서, 이와 같은 인조피혁을 적정 입력을 가한 열처리로서 일정한 형태를 갖는 케이스를 성형할 수 있음을 예상할 수 있는 것이며, 상기 피혁을 단순히 절곡, 성형할 경우 복원력이 강한 재질상의 특징으로 형태가 일그러짐을 알 수 있다.Therefore, it can be expected that a case having a certain shape can be formed as a heat treatment to which such an artificial leather is applied with a proper input, and when the leather is simply bent and molded, the shape is distorted due to a material having strong restoring force. Able to know.
종래에는 인조가죽을 이용한 가방 또는 카메라등의 케이스를 제작하기 위해서는 평편한 시이트(원단)를 선택된 형으로 다수로 재단한 다음 봉재하여 연결시켜주는 수공 내지는 반수공의 수단으로 행하고 있다.Conventionally, in order to manufacture a case such as a bag or a camera using artificial leather, a flat sheet (fabric) is made by hand or semi-manual means of cutting a plurality of flat sheets into a selected shape and then connecting them by sewing.
이때의 피혁연결부위는 그 부피가 2배로 두꺼워지고 연결부위의 많은 봉재선에 의하여 외관이 수려하지 못할뿐 아니라 특히, 가공 공정이 길어지고 인건비가 과다하게 소요되는등 제품의 단가가 상승되는 요인이 되었던 것이다.At this time, the leather connection part was doubled in volume and not only beautiful in appearance due to the many seams of the connection part, but also the cost of the product increased due to the long processing process and excessive labor cost. will be.
본 발명은, 이와 같은 종래의 재래식 가공방법을 탈피하여 프레스가공에 의한 열처리로 외관이 미려한 양산체제를 갖출 수 있는 그 제조방법을 제공하고자 하는 것으로, 이를 아래 실시예에 의해 상세히 설명하면 다음과 같다.The present invention is to provide a manufacturing method that can be equipped with a mass production system with a beautiful appearance by heat treatment by press processing to escape the conventional processing method as described above, which will be described in detail by the following examples. .
[실시예]EXAMPLE
용도에 따라 소망크기로 절단된 원단(인조피혁)을 선택된 형틀로 제작된 금형으로 파워 약 1t으로 프레스함과 동시에 130℃-180℃의 열로 5초 내지 20초 정도 가열한 다음 압축된 상태에서 약 20초 냉풍을 공급하여 냉각하게 된다.Depending on the application, the fabric (artificial leather) cut to a desired size is pressed into a mold made of a selected mold with a power of about 1 ton, heated at 130 ° C to 180 ° C for 5 to 20 seconds, and then compressed in a compressed state. Cooling by supplying 20 second cold wind.
상기 실시예에서 분리, 성형된 케이스를 결합하면 도면 제1도에 도시된 바와 같이 하나의 제품을 완성되는 것으로 최대한의 봉제선을 배제할 수 있다.In the above embodiment, when the separated and molded case is combined, the maximum seam may be eliminated by completing one product as shown in FIG. 1.
한편, 본 발명의 실시예에서 제공되는 파워 약 1t의 프레스 가공 및 130°-180℃의 가열온도는 피혁의 두께에 따라 선택되는 것으로, 즉, 통상의 인조피혁은 0.8m/m-2m/m정도로서 가볍고 질긴 특성이 있다.On the other hand, the press work of about 1 ton power provided in the embodiment of the present invention and the heating temperature of 130 °-180 ° C is selected according to the thickness of the leather, that is, the ordinary artificial leather is 0.8 m / m-2 m / m There is light and tough characteristic as precision.
따라서, 두께가 2m/m미만의 원단일 경우 1t미만의 적정파워로 가능하며 가열온도 역시 130℃이상 180℃이하 사이에서 적절히 조정하게 된다.Therefore, when the thickness of the fabric less than 2m / m is possible with a proper power of less than 1t and the heating temperature is also properly adjusted between 130 ℃ and 180 ℃ or less.
또한, 상기 원단의 경우 180℃의 가열온도로서 약 20초가 경과하면 융해되므로 20초 정도가 가장 바람직한 성형의 효과를 기대할 수 있는 것으로 이는 본 발명의 실험에서 얻어진 적절한 수치인 것이다.In addition, in the case of the fabric is melted when the elapse of about 20 seconds as the heating temperature of 180 ℃ can be expected the effect of the most preferred molding about 20 seconds that is the appropriate value obtained in the experiment of the present invention.
한편, 가열온도가 100℃이하로 할 경우 성형상태가 불량하여 성형후 피혁이 원상태로 복귀됨을 발견할 수 있다.On the other hand, if the heating temperature is less than 100 ℃ it can be found that the molding state is poor and the leather is returned to its original state after molding.
그리고, 냉풍공급시간도 20초를 경과할 경우 피혁의 표면이 균열된 우려가 있으며 다음 공정, 즉 본드 접착이나 고주파처리 및 기타 봉제공정에 지장을 초래하게 된다.In addition, if the cold air supply time also passes 20 seconds, there is a fear that the surface of the leather is cracked, causing problems in the next process, that is, bond bonding, high frequency treatment and other sewing processes.
상기 상술한 바와 같이 본 발명은 도면에 표현된 카메라 케이스를 예를 들 경우, 몸체의 앞판과 뒷판을 단 두번의 프레스 가공으로 성형되며, 덮개를 포함하여 3개의 금형으로 양산되고 동시에 봉제선이 극히 배제된 미려하고 고급화된 제품을 대량 생산에 의하여 저렴하게 제공할 수 있는 것이다.As described above, in the case of the camera case represented in the drawing, for example, the front plate and the back plate of the body are molded by only two presses, including a cover, mass produced in three molds, and at the same time, the seam is extremely excluded. It is possible to provide a beautiful and high-quality products inexpensively by mass production.
