본 발명은 초음파 융착을 이용한 기밀형 안전보호복의 제조방법 및 제조장치에 관한 것으로, 보다 구체적으로는 초음파의 에너지를 이용하여 안전보호복에 사용되는 화학섬유의 원단을 용융점이상으로 가열시켜 녹인 후에 압력을 가하여 접합시키는 안전보호복 제조방법 및 제조장치에 관한 것이다. The present invention relates to a method and apparatus for manufacturing an airtight safety protective clothing using ultrasonic welding, and more specifically, by heating the fabric of the chemical fiber used in the safety protective clothing using the energy of ultrasonic wave to melt above the melting point. The present invention relates to a method for manufacturing safety protective clothing and a device for joining by applying pressure.

"안전보호복"은 작업을 진행하는 장소에서 작업으로 인해서 또는 작업장 자체에서 발생하는 유해환경으로부터 작업자를 보호하기 위해서 착용하는 보호복을 의미하는 것으로서, 유해환경에서 발생하는 분진이나 액체 및 기체상태로 날아다니는 미세한 화학독성물질들이 신체에 직접적으로 접촉하지 못하도록 차단해 주는 역할을 함과 동시에, 작업을 수행하면서 신체의 움직임으로 발생하게 되는 신체의 땀과 열을 보호복 밖으로 발산시켜줌으로써 쾌적성을 항상시켜 작업의 능률을 높이는 역할을 하게 된다. "Safety protective clothing" means protective clothing which is worn to protect workers from the hazardous environment caused by the work or the workplace itself in the place where the work is carried out. It acts as a barrier to the direct flying of the tiny chemical toxic substances, while at the same time it releases the body's sweat and heat from the body's movements as it moves out of the protective suit. This will increase the efficiency of your work.

즉, 안전보호복은 유해환경으로부터 작업자를 보호하는 역할과 함께 작업의 쾌적성을 높여주어 작업의 능률을 향상시켜주기 때문에 안전사고 예방차원에서 그리고 작업자를 보호하고자 하는 노조 및 사주의 안전의식 향상으로 인하여 향후 그 수요가 더욱 확대될 전망이다. In other words, safety protective suits protect workers from harmful environments and improve work efficiency, thereby improving work efficiency. As such, demand is expected to expand further.

근래에 작업자들의 유해환경에서 작업하는 것을 기피하는 현상과 함께 안전사고 방지를 위해서 정부의 홍보 및 안전규격 강화로 인하여 보호복을 의무적으로 착용하는 곳이 늘어나게 되었으며 이와 함께 품질도 높아지게 되었다. 단순하게 외부물질의 침투를 차단해 주던 기능에서 더 나아가 작업자들이 발산하는 땀과 열에너지를 적극적으로 보호복 밖으로 배출해 줄 수 있는 투습기능이 보강되었다. 보호복에 사용되는 원단은 외부에서 침투하는 이물질을 차단할 수 있으며 열과 함께 땀입자가 발산될 수 있도록 미세한 기공이 형성되어 있다. In recent years, due to the government's avoidance of working in hazardous environments and to prevent safety accidents, the number of mandatory wearing of protective clothing has increased due to the government's publicity and strengthened safety standards. In addition to the function of simply blocking the infiltration of foreign substances, the moisture permeation function that can actively discharge the sweat and heat energy emitted by workers out of the protective suit has been reinforced. The fabric used in the protective clothing can block foreign matter penetrating from the outside, and minute pores are formed to release sweat particles with heat.

한편, 일반적인 안전보호복의 제조과정을 보면, 원단을 검단하고 패턴을 CAD로 설계하여 각각의 패턴을 프린트한 후에 이를 원단에 마킹작업과 함께 각각의 패턴을 생산량에 따라서 원단을 겹쳐서 재단을 하게 되고, 이어서 각각의 패턴조각과 원부자재를 사용하여 재봉하고 재봉부위를 씸실링 테이프로 열접착시켜서 완성하게 된다. On the other hand, in the manufacturing process of general safety protective clothing, the fabric is inspected and the pattern is designed by CAD, and after each pattern is printed, the pattern is printed on the fabric and each pattern is cut by overlapping the fabric according to the production volume. Then, each pattern piece and the raw material is sewn using the sewing portion is heat-sealed with heat sealing tape is completed.

그런데, 일반적인 봉제방법에 의하여 안전보호복을 제작하는 경우에는 봉사를 사용하여 원단을 합복시키게 되는데, 이때 톱니, 노루발의 압력, 봉사장력 및 원단의 종류에 의하여 각각의 조합이 완전히 맞지 않을 경우에 봉제선의 솔기(seam) 주위에 원하지 않은 작은 주름이 발생하는 퍼커링(puckering) 현상이 일어나게 된다. By the way, in the case of manufacturing a safety protective suit by the normal sewing method is to use the service cloth to combine the fabric, in which case each combination is not completely matched by the tooth, the pressure of the presser foot, the service tension and the type of fabric Puckering, which causes unwanted small creases around the seam, occurs.

안전보호복의 경우에는 솔기부분으로 분진이나 화학물질이 침투할 수 있기 때문에 테이프로 열접착시키는 씸씰링(seam sealing) 공정을 통하여 이러한 부분까지 막아주게 된다. 특별히 퍼커링이 일어난 부분은 씸씰링 작업이 매우 어려워서 불량이 나기 쉽기 때문에 완성된 제품이 사소한 실수로 인하여 불량처리하게 되어서 이 부분이 인건비의 70% 이상을 차지하고 임가공의 손실 비용의 대부분을 차지하게 된다. 따라서, 생산성 향상을 위해서 이러한 문제점을 해결한 새로운 안전보호복의 제조방법이 절실히 요구되고 있다.In the case of safety protective clothing, dust or chemicals can penetrate into the seam, and this is prevented through a seam sealing process that is thermally bonded with tape. Particularly, the part where perkering occurred is very difficult to make the seal sealing work, so the finished product is treated poorly due to the minor mistake, and this part takes up more than 70% of the labor cost and takes up most of the loss cost of processing. . Therefore, there is an urgent need for a method of manufacturing a new safety protective clothing that solves these problems in order to improve productivity.

본 발명은, 봉사 장력과 노루발 압력과 원단의 특성으로 인하여 씸 퍼커링(seam puckering)이 발생하게 되어 봉제공정이 불량하게 되는 문제점을 해결할 수 있는, 안전보호복의 제조방법 및 제조장치를 제공하려는 것이다.The present invention is to provide a method and apparatus for manufacturing safety protective clothing that can solve the problem that the sew puckering occurs due to the service tension, the presser foot pressure and the characteristics of the fabric, the sewing process is poor. will be.

또한, 본 발명은 솔기의 접합부위를 씸테이프로 열접착시키는 씸씰링공정상의 불량을 제거할 수 있는 안전보호복의 제조방법 및 제조장치를 제공하려는 것이다.In addition, the present invention is to provide a method and apparatus for manufacturing safety protective clothing that can eliminate the defects in the heat sealing process to heat-bond the joint of the seam with a wet tape.

또한, 본 발명은 일반 봉제 공정보다 훨씬 간단한 공정을 통해서 인건비의 비중을 줄이면서 생산성을 향상시킬 수 있는 경제적인 안전보호복의 제조방법 및 제조장치를 제공하려는 것이다.In addition, the present invention is to provide a method and apparatus for manufacturing an economic safety protective clothing that can improve productivity while reducing the weight of labor through a much simpler process than the normal sewing process.

또한, 본 발명은 안전보호복을 만든 후에도, 융착부위가 반복하여 굽혀지는 현상에 대해서 내구성을 가지며 반복하여 세탁하여도 사용이 가능한 안전보호복의 제조방법 및 제조장치를 제공하려는 것이다. In addition, the present invention is to provide a method and apparatus for manufacturing a safety protective clothing that can be used even after repeated washing, having a durability against the phenomenon that the fusion site is repeatedly bent, even after making the safety protective clothing.

상기와 같은 목적을 달성하기 위하여, 본 발명은 아래와 같은 단계를 포함하는 초음파 융착을 이용한 안전보호복의 제조방법을 제공한다. In order to achieve the above object, the present invention provides a method for manufacturing a safety protective suit using ultrasonic welding comprising the following steps.

a. 두장의 원단을 공급하는 단계a. Supplying two sheets of fabric

바람직하게는, 상기 b 단계 이후 b1. 상기 원단의 테두리가 정확하게 일치하지 않는 경우 일정부분을 절단하여 원단 테두리의 끝을 일치하도록 맞추는 단계를 추가적으로 포함할 수 있다. Preferably, after step b b1. If the edges of the fabric do not match exactly, cutting the predetermined portion may further include a step of matching the ends of the fabric border.

이하, 상기 안전보호복을 초음파 융착에 의하여 기밀을 유지한 채로 제조하는 방법 및 그 제조장치에 대하여 각 단계별로 상세하게 설명한다.Hereinafter, a method for manufacturing the safety protective clothing while maintaining hermeticity by ultrasonic welding and a manufacturing apparatus thereof will be described in detail for each step.

a. 두장의 원단을 공급하는 단계a. Supplying two sheets of fabric

상기 a 단계는, 원단을 일정하게 공급하는 단계이다. 원단은 안전보호복을 제조하기 위한 것으로, 여기서 사용되는 원단의 주 재료는 화학섬유이며 다른 재료로 구성된 멀티레이어(multi-layer)의 재료도 가능하다. 다만, 이러한 경우 접합시키고자 하는 부위의 양쪽 원단의 융착부분이 화학섬유로 구성되어 있어서 융착에 아무런 문제가 없어야 한다. Step a is a step of constantly supplying the fabric. Fabrics are intended for the manufacture of safety protective clothing, where the main material of the fabrics used is chemical fiber and a multi-layer material composed of other materials is also possible. In this case, however, the fusion portions of both fabrics of the portion to be bonded should be composed of chemical fibers, so there should be no problem in fusion.

일반적으로 사용이 가능한 원단의 재료는 폴리올레핀, 폴리에스터, 나일론, PVC 등이며 두께는 박지직물 및 후지직물을 모두 사용이 가능하도록 설계하여 0.5~20 mm까지 사용이 가능하지만, 이에 한정되지 않는다.In general, the material of the fabric that can be used is polyolefin, polyester, nylon, PVC and the like and the thickness is designed to be used for both fabric and Fuji fabric can be used up to 0.5 ~ 20 mm, but is not limited thereto.

원단은 보통 2장이 공급되며, 2장의 원단을 서로 연결하여 보호복을 제작하게 된다. 원단은 도 3과 같이 끝단이 서로 일부분 겹쳐지도록 서로 같은 방향의 끝단이 겹쳐지도록 공급될 수 있으며, 또한 도 4에서와 같이 완전히 겹쳐진 채로 겹쳐진 부분의 끝단이 서로 융착될 수 있도록 제공될 수 있다. Two pieces of fabric are usually supplied, and two pieces of fabric are connected to each other to produce a protective suit. The fabric may be supplied such that the ends in the same direction overlap each other so that the ends overlap with each other as shown in FIG. 3, and may also be provided so that the ends of the overlapped portions may be fused together as shown in FIG. 4.

원단의 공급은 도 2에서와 같이 공급롤러(11)를 통해 자동적으로 공급될 수 있으며, 2개의 원단이 각각 공급되도록 공급롤러(11)를 복수개 형성할 수 있다. 상기 공급롤러(11)는 원단을 맞물려서 일정한 속도로 투입이 되도록 공급하게 된다. The supply of the fabric may be automatically supplied through the supply roller 11 as shown in FIG. 2, and a plurality of supply rollers 11 may be formed to supply two fabrics, respectively. The feed roller 11 is supplied to be fed at a constant speed by engaging the fabric.

b. 상기 원단이 서로 일정부분 겹치도록 상기 원단의 테두리를 자동으로 맞추는 단계b. Automatically aligning the edges of the fabric so that the fabric overlaps with one another;

상기 b 단계는, 원단을 공급롤러에 맞물려 투입하고, 원단의 일정부분이 겹치도록 원단의 테두리를 자동으로 맞추는 단계이다. 원단 2장을 자동으로 투입하는 경우, 원단의 끝부분이 일정하게 맞추어 지는 경우가 거의 없게 되기 때문에 자동맞춤장치를 통해서 원단을 어느 정도 맞물려 작업이 가능하도록 맞추어 준다. The step b is to insert the fabric into the feed roller and automatically adjust the edge of the fabric so that a predetermined portion of the fabric overlaps. In case of automatically inserting two pieces of fabric, the ends of the piece of fabric are almost never matched with each other.

자동맞춤장치(15)의 일 실시예가 도 3에 도시되어 있다. 도 3의 자동맞춤장치(15)는 원단 하나를 평면상에서 지지하도록 평판으로 형성되고, 일측 끝단이 절곡된 제1 공급 플레이트(151)와, 다른 원단을 평면상에서 지지하도록 평판으로 형성되고, 일측 끝단이 절곡된 제2 공급 플레이트(152)를 포함한다. One embodiment of the automatic fit device 15 is shown in FIG. 3. The automatic fitting device 15 of FIG. 3 is formed of a flat plate to support one fabric in a plane, a first supply plate 151 bent at one end, and a flat plate to support another fabric in a plane, and one end This bent second supply plate 152 is included.

도 3(a)에서와 같이 제1 공급 플레이트(151)는 대부분이 평판형으로 형성되지만 측면 끝단이 ㄷ자 형으로 절곡되어 형성된다. 즉, 절곡된 제1 가이드(153)를 형성하게 되며, 이러한 가이드는 원단의 측면 끝단과 접촉하게 되어 원단의 배출이 정확하게 되도록 유도하는 기능을 한다. 마찬가지로 제2 공급 플레이트(152) 역시 일측 끝에 절곡된 제2 가이드(154)가 형성된다. As shown in FIG. 3 (a), the first supply plate 151 is formed in a flat shape, but the side end is bent in a c-shape. That is, the bent first guide 153 is formed, and the guide is in contact with the side end of the fabric to induce the discharge of the fabric to be accurate. Similarly, the second supply plate 152 is also formed with a second guide 154 bent at one end.

도 3(b)에서와 같이, 제1 공급 플레이트와 제2 공급 플레이트의 가이드는 배출측에서 서로 겹쳐지도록 형성되며, 제1 공급 플레이트(151)에 원단 A가 공급되고, 제2 공급 플레이트(152)에 원단 B가 공급된다. 이와 같이 겹쳐진 폭 만큼 원단들이 서로 겹쳐진 상태로 배출된다. As shown in FIG. 3B, the guides of the first supply plate and the second supply plate are formed to overlap each other at the discharge side, and the fabric A is supplied to the first supply plate 151, and the second supply plate 152 is provided. ) Fabric B is supplied. The fabrics are discharged in the overlapped state by the overlapped width.

또한 자동맞춤장치의 공급 플레이트들(151,152)은 (a)에서와 같이 배출측이 서로 겹쳐지도록 되나, 공급원단을 받는 부분(공급측)에서는 서로 일정거리 이격되어 완전히 분리된 상태로 원단이 공급될 수 있도록 한다. 즉, 각 원단은 배출측을 향해 모아질 수 있도록 경로가 형성된다. 또한 도 3(a)에서와 같이 좌우 양측으로 분리 공급되도록 할 수 있으나, 이에 한정되는 것은 아니고 상하로 분리되도록 도 3(b)와 같이 형성할 수도 있다. In addition, the supply plates 151 and 152 of the automatic alignment device are to have the discharge side overlap each other, as in (a), but in the part (supply side) receiving the supply source, the fabric can be supplied in a completely separated state spaced apart from each other. Make sure That is, the path is formed so that each fabric can be collected toward the discharge side. In addition, as shown in Figure 3 (a) may be supplied separately to the left and right sides, but is not limited to this may be formed as shown in Figure 3 (b) to be separated up and down.

이와 같이 자동맞춤장치의 배출측에서 원단이 모아지고, 자동맞춤장치의 공급측에서는 원단이 각각 분리된 상태로 진행되도록 하기 위하여 상기 a 단계에서 미리 원단을 각각 개별적으로 분리된 경로로 공급하도록 할 수 있고, 또한 도 2에서와 같이 분리장치(13)를 사용할 수도 있다. In this way, the fabric is collected at the discharge side of the automatic alignment device, and the supply side of the automatic alignment device can be supplied in a separate path in advance in each of the fabrics in step a in order to proceed in a separate state. In addition, the separator 13 may be used as shown in FIG. 2.

분리장치(13)는 원단이 동시에 같은 경로로 공급될 경우에 두 원단을 분리하기 위한 것으로, 쐐기형으로 형성되며, 원단을 상하로 나누게 된다. 이 경우 원단은 상하로 구분되어 경로를 진행하게 되며, 다시 도 3에서와 같은 자동맞춤장치의 각각의 공급측에 투입된다. Separator 13 is for separating the two fabrics when the fabric is fed in the same path at the same time, is formed in a wedge shape, and the fabric is divided into up and down. In this case, the fabric is divided into upper and lower portions and proceeds through the path, and is again fed to each supply side of the automatic alignment device as shown in FIG. 3.

한편, 자동맞춤장치의 다른 실시예가 도 4에 도시되어 있다. 도 4의 자동맞춤장치(16)는 원단 하나를 평면상에서 지지하도록 평판으로 형성되고, 일측 끝단이 절곡된 제1 공급 플레이트(161)와, 다른 원단을 평면상에서 지지하도록 평판으로 형성되고, 일측 끝단이 절곡된 제2 공급 플레이트(162)를 포함하고, 제1 가이드(163) 및 제2 가이드(164)를 포함하는 것은 도 3에서와 동일하다. On the other hand, another embodiment of the automatic alignment device is shown in FIG. 4 is formed of a flat plate to support one fabric in a plane, one end of the first supply plate 161 is bent, a flat plate to support the other fabric in a plane, one end It is the same as in FIG. 3 including the bent second supply plate 162 and including the first guide 163 and the second guide 164.

도 4의 자동맞춤장치(16)는 원단이 서로 겹쳐진 상태로 동일한 끝단이 융착될 수 있도록 맞추어지는 것을 도시하였다. 이를 위해 제1 가이드(163) 및 제2 가이드(164)가 서로 같은 방향에 형성된다. 4 shows that the self-aligning device 16 is fitted so that the same ends can be fused in the state in which the original fabrics overlap each other. To this end, the first guide 163 and the second guide 164 are formed in the same direction.

도 4 (a)는 배출측이 서로 겹쳐진 상태로 형성되고, 공급측이 좌우로 벌어진 상태로 형성되어, 원단이 서로 다른 경로를 통해 공급될 수 있는 상태를 도시한 것이다. 한편 도 4(b)는 배출측이 역시 서로 겹쳐진 상태로 형성되나, 공급측이 상하로 벌어진 상태로 공급되는 것을 도시한 것이다. Figure 4 (a) is a state in which the discharge side is formed in a state overlapping each other, the supply side is formed in a state spreading left and right, it shows a state that the fabric can be supplied through different paths. On the other hand, Figure 4 (b) shows that the discharge side is also formed in a state overlapping with each other, the supply side is supplied in a state spread up and down.

b1. 상기 원단의 테두리가 정확하게 일치하지 않는 경우 일정부분을 절단하여 원단 테두리의 끝을 일치하도록 맞추는 단계b1. If the edges of the fabric do not match exactly, cutting a certain portion to match the ends of the fabric border

상기 b1 단계는, 원단을 다음의 작업이 용이하도록 끝부분을 깨끗하게 커팅하여 주는 단계이다. 상기 b단계를 거쳐 두장의 원단이 자동으로 맞춰진 상태에서 테두리가 초음파 융착을 하게 되는데, 각각의 원단을 겹쳐서 공급될 경우에 끝부분이 일정하게 맞지 않을 수도 있고 두께가 얇은 박지직물의 종류에 따라서 끝부분이 겹쳐서 나올 수 있기 때문에 이런 부분들을 자동절단장치(17)로 절단하는 단계를 거칠 수 있다. The b1 step is a step for cutting the end of the fabric to facilitate the next operation. In the state where the two pieces of fabric are automatically adjusted through the b step, the edge is ultrasonically fused. When overlapping each piece of fabric, the ends may not be consistent and the ends may be thin depending on the type of thin paper fabric. Since the parts may overlap, the steps may be cut by the automatic cutting device 17.

상기 자동절단장치(17)는 융착현상이 발생하지 않을 부분이 있으면 추후에 걸림현상으로 인하여 찢어지는 원인이 되고 반복적인 굽힘현상에 의해서 쉽게 약화되어 이물질이 침투하는 현상이 발생할 수도 있기 때문에 융착현상이 일어나지 않는 맨 끝단 부분을 자동으로 절단하는 장치이다. 불필요한 부분은 원단이 지나갈 때 커터에 의해서 끊어져서 떨어져 나간다.If the automatic cutting device 17 has a portion where the fusion phenomenon does not occur, it may cause tearing later due to the jamming phenomenon, and the fusion phenomenon may occur because the foreign material may easily be weakened by the repeated bending phenomenon. It is a device that automatically cuts the last part that does not happen. Unnecessary parts are broken off by the cutter as the fabric passes by and fall off.

c. 상기 원단의 겹쳐진 부분의 두께에 따라서 패턴롤러의 높이를 조절하는 단계c. Adjusting the height of the pattern roller according to the thickness of the overlapping portion of the fabric

상기 c 단계는, 원단의 두께에 따라서 융착의 정도가 달라지기 때문에 최적의 융착이 되도록 하기 위해서는 원단의 두께에 따라서 눌러주는 압력이 달라지도록 조절해 주는 단계이다. 이를 위하여 높이조절장치(19)를 거치게 된다. In step c, the degree of fusion varies depending on the thickness of the fabric, so that the pressing pressure is varied according to the thickness of the fabric in order to achieve optimal fusion. To this end, the height adjusting device 19 is passed.

상기 높이조절 장치(19)는 에어컴퓨레셔에 의하여 패턴롤러가 원단의 두께와 종류에 상관없이 원단과 어느 정도의 압력으로 가하여 지는지 측정을 하여 초음파 진동자에 의하여 전달되는 에너지에 의하여 원단이 잘 용융될 수 있도록 높이를 자동으로 조절해 준다. The height adjusting device 19 measures the amount of pressure applied to the pattern roller by the air compressor, regardless of the thickness and type of the fabric, so that the fabric melts well by the energy transmitted by the ultrasonic vibrator. The height is adjusted automatically so that it can

에어컴퓨레셔의 압력은 박지직물의 경우 3~4.5 bar, 후지직물의 경우 5~6.5 bar 의 압력이 가하여 지게 된다. 사용되는 원단의 두께는 일반적으로 0.5~20 mm 이며 초음파 융착이 가장 잘 일어날 수 있는 높이는 융착속도 및 원단의 재질의 종류, 초음파 진동자에서 발진하는 에너지의 량에 따라서 달라질 수 있는데 일반적으로 0.5~10 mm 가 바람직하지만, 이에 한정되지 않는다.The pressure of the air compressor is applied at a pressure of 3 to 4.5 bar for paper and 5 to 6.5 bar for Fuji. The thickness of the fabric used is generally 0.5 ~ 20 mm and the height at which ultrasonic welding can occur most can vary depending on the welding speed, the type of material of the fabric, and the amount of energy generated by the ultrasonic vibrator. Is preferred, but is not limited thereto.

높이조절장치(19)는 도 5에서와 같이 패턴롤러의 지지대에 스프링(199)을 장착하여 패턴롤러가 일정한 압력으로 원단을 압축하도록 한다. 패턴롤러는 스프링(199)에 의해 원단의 두께에 따라 탄성적으로 상승 또는 하강할 수 있도록 높이 조절 기능을 하게 된다. Height adjusting device 19 is mounted on the support of the pattern roller spring 199 as shown in Figure 5 so that the pattern roller compresses the fabric at a constant pressure. The pattern roller has a height adjustment function to elastically rise or fall by the spring 199 according to the thickness of the fabric.

d. 상기 패턴롤러에 초음파 발생기를 통해 에너지를 전달하여 상기 원단의 겹쳐진 부분을 용융 및 접착시키는 단계d. Melting and bonding the overlapping portions of the fabric by transmitting energy to the pattern roller through an ultrasonic generator

상기 d 단계는, 초음파 발생기에 의해서 발생된 에너지가 성형을 위한 패턴롤러로 이동하면서 원단을 용융시키고 접착시키는 단계이다. 초음파 발생기(21)는 도 5에 도시한 바와 같이, 진동자(211), 부스터(212) 및 공구혼(213)을 포함하고 있다. Step d is a step of melting and adhering the fabric while moving the energy generated by the ultrasonic generator to the pattern roller for molding. As illustrated in FIG. 5, the ultrasonic generator 21 includes a vibrator 211, a booster 212, and a tool horn 213.

초음파 발생장치에 AC 220 V (50~60 Hz)의 전원이 공급되면 이를 15~50 KHz의 전기에너지로 변환시켜 진동자(211)에 전달한다. 전기에너지를 공급받은 진동자(transducer, 211)는 이를 기계적 진동에너지로 변환시켜 주면서 부스터(booster, 212) 및 공구혼(tool-horn, 213)으로 전달한다. 이때 진폭확대가 조절되고 가압하면서 초음파 에너지가 열가소성물질에 순간적으로 마찰열을 발생시키면서 강력한 분자적 결합이 이루어지게 된다. 여기서 공구혼(213)은 원형의 접시모양이며 분자결합에 의하여 열가소성물질이 원판에 눌러붙는 것을 방지하기 위해서 일정한 속도로 회전운동을 한다. 회전속도는 초음파 재봉기의 속도에 비례한다.When AC 220 V (50 ~ 60 Hz) power is supplied to the ultrasonic generator, it is converted into electric energy of 15-50 KHz and transmitted to the vibrator 211. Transducer 211 supplied with electrical energy converts it into mechanical vibration energy and transmits it to the booster 212 and the tool-horn 213. At this time, while the amplitude expansion is adjusted and pressurized, the ultrasonic energy generates a frictional heat instantaneously to the thermoplastic material and a strong molecular bond is made. Here, the tool horn 213 has a circular plate shape and rotates at a constant speed in order to prevent the thermoplastic material from being pressed onto the disc by molecular bonding. The rotation speed is proportional to the speed of the ultrasonic sewing machine.

한편, 이와 같이 전달되는 진동주파수(진동 에너지)는 혼(213)의 상부에 있는 패턴롤러(31)로 이동되며, 혼을 포함한 초음파 발생기(21)와 패턴롤러(31)는 각각의 재질 및 기계적인 특성에 의해 진동주파수의 이동범위가 다르기 때문에 초음파 발생기와 패턴롤러의 접촉면에서는 진동주파수의 이동범위의 차이에서 오는 진동 마찰열에 의해 고열이 발생하게 된다. 이때 초음파 발생기와 패턴롤러의 사이에 위치하고 있는 원단이 진동마찰열에 의해 용융된다. On the other hand, the vibration frequency (vibration energy) transmitted in this way is moved to the pattern roller 31 at the top of the horn 213, the ultrasonic generator 21 and the pattern roller 31 including the horn is made of each material and machine Since the range of movement of the oscillation frequency varies depending on the characteristics, high heat is generated at the contact surface of the ultrasonic generator and the pattern roller by vibrating frictional heat resulting from the difference of the range of the oscillation frequency. At this time, the fabric located between the ultrasonic generator and the pattern roller is melted by vibration frictional heat.

또한, 이와 같이 원단의 겹쳐진 부분을 용융시키고 패턴롤러(31)를 통해 도 5에서와 같이 접착 성형한다. 이때 패턴롤러(31)는 롤러에 돌출된 패턴부(33)가 형성되며, 이러한 패턴부는 원단을 여러 가지 종류의 패턴으로 디자인하기 위해 다양하게 형성될 수 있다. In addition, the overlapped portions of the fabric are melted and adhesively molded as shown in FIG. 5 through the pattern roller 31. At this time, the pattern roller 31 is formed with a pattern portion 33 protruding from the roller, this pattern portion may be formed in various ways to design the fabric in various types of patterns.

패턴롤러(31)의 패턴(C)은 도 6(a)에서와 접착된 부분의 상하가 서로 뚫려있지 않고 완전히 분리되도록 성형한다. 안전보호복의 경우 원단을 연결한 부위로 화학 물질 등이 침투하지 않도록 하기 위한 것으로, 완전히 밀봉할 수 있도록 연속된 융착 부분을 제공하여야 한다. 패턴롤러에 의하여 융착이 완성된 부분은 충분한 인장강도를 유지하여 주면서 액체나 기체상태로 침투할 수 있는 독성물질을 차단하는 역할을 한다.The pattern C of the pattern roller 31 is molded such that the upper and lower portions of the bonded portion of the pattern roller 31 are separated from each other without being bored. In the case of safety protective clothing, it is to prevent chemicals from penetrating into the part where the fabric is connected, and a continuous fusion part is to be provided so that it can be completely sealed. The fusion completed by the pattern roller blocks the toxic substances that can penetrate into the liquid or gas phase while maintaining sufficient tensile strength.

따라서 상기 패턴롤러(31)에는 용도에 맞게 다양한 디자인으로 패턴을 각인할 수 있는데, 용융된 원단부분을 가압하에 지나가면서 접착을 시켜주기 때문에 인장강도를 높여주고 융착된 부분의 상하를 분리하여 기밀을 형성시켜줌으로써 액체나 기체상태로 침투할 수 있는 독성물질을 차단하는 역할을 한다.Therefore, the pattern roller 31 can be imprinted with a pattern in a variety of designs according to the application, because the melted fabric portion is bonded while passing under pressure to increase the tensile strength and separate the upper and lower sides of the fused portion to ensure airtightness. It forms a barrier to toxic substances that can penetrate into liquid or gaseous form.

만일 패턴이 도 6(b)에서와 같이 상하로 뚫려있는 패턴(D)으로 형성되면 융착부의 틈새로 화학물질들이 통과할 수 있게 되어 완벽한 밀봉기능을 하지 못한다. If the pattern is formed as a pattern (D) that is drilled up and down as shown in Figure 6 (b) it can not pass through the chemicals through the gap of the fusion is not a perfect sealing function.

또한, 본 발명의 초음파를 이용한 기밀형 안전보호복의 제조장치는, 씸씰링 공정에서 인건비의 70%가 들어가고 씸씰링 테이프가 고가이기 때문에 이에 따른 부자재 비용이 많이 산정이 되는데, 초음파 융착에 의해서 보호복의 원단이 접합되기 때문에 인건비 및 부자재 비용을 줄일 수 있어서 생산단가가 낮아지게 되고 동시에 단위 시간당 생산량을 향상시킬 수 있다. In addition, the manufacturing apparatus of the hermetic safety protective clothing using the ultrasonic wave of the present invention, since 70% of the labor cost in the sealing process and the sealing tape is expensive, the cost of the subsidiary materials is largely calculated accordingly, protection by ultrasonic welding Since the fabric of the garment is bonded, labor and subsidiary material costs can be reduced, resulting in lower production costs and at the same time improving the output per unit time.
