Description

고주파유도가열기를 이용한 합성수지시트 접착기{High-frequency induction heating welder for synthetic resin sheet}High-frequency induction heating welder for synthetic resin sheet

본 발명은 금형을 이용한 합성수지시트 접착기에 관한 것이다.The present invention relates to a synthetic resin sheet adhesive machine using a mold.

의류, 신발, 가방 등의 제조분야에서 합성수지는 그 소재로서 광범위하게 사용되고 있다. 이러한 합성수지 소재로 완제품을 제조하기 위해서는 합성수지와 타소재와의 접착 혹은 합성수지간의 접착공정이 흔히 요구되는데, 현재 합성수지 소재로 많이 사용되고 있는 PVC 등 비환경친화적 소재의 접착방법으로는 고주파 유전가열 방식이 사용되고 있다.Synthetic resin is widely used as a material in the manufacturing field of clothing, shoes, bags and the like. In order to manufacture the finished product from such synthetic resin materials, it is often required to bond the synthetic resin with other materials or the adhesive process between synthetic resins.A high-frequency dielectric heating method is used as an adhesive method for non-environmentally friendly materials such as PVC, which is currently used as a synthetic resin material. have.

이 고주파 유전가열에 의한 PVC 등 합성수지 소재의 접착원리는 다음과 같다.The bonding principle of the synthetic resin material such as PVC by the high frequency dielectric heating is as follows.

전극간에 부도체인 피가열물을 넣고 양전극에 고주파 전압을 가하면 부도체(유전체)를 구성하고 있는 쌍극자가 교류 전계의 교번에 따라 방향을 변경하면서 인가 주파수와 동일한 진동을 일으키게 되고 이 진동에 의해 부도체는 발열하게 된다. 이 방식에서 가열효과를 높이는 방안은 쌍극자의 진동을 빠르게 하거나 인가 전압을 높이는 것이다. 이러한 유전가열에 사용되는 주파수는 보통 10 MHz 정도로 아주 높은 주파수가 사용되어진다. 이 방법은 유전 손실이 많은 PVC와 같은 비환경친화적 합성수지 등의 접착과 성형에 사용되고 있다.When a heating object, which is a non-conductor, is applied between electrodes, and a high frequency voltage is applied to both electrodes, the dipoles constituting the insulator (dielectric) change direction according to the alternating current of the alternating electric field, causing the same vibration as that of the applied frequency. Done. In this way, the heating effect is to increase the dipole vibration or increase the applied voltage. The frequency used for such dielectric heating is usually very high frequency of about 10 MHz. This method is used for bonding and forming non-environmentally friendly synthetic resins such as PVC, which have high dielectric loss.

상기의 고주파 유전가열 방식은 가열시간이 매우 짧아서 소재의 순간접착이 가능하며, 소재 전체에 균일하게 열이 발생하게 되므로 접착후 소재의 변형억제, 소재냉각 등의 면에서 우수한 기술이라고 할 수 있다.The high frequency dielectric heating method is a very short heating time is possible to instantaneous adhesion of the material, since the heat is generated uniformly throughout the material can be said to be an excellent technology in terms of suppressing deformation of the material after bonding, material cooling.

그러나, 이러한 고주파 유전가열에 의한 접착방식은 그 원리상 유전손실이 낮은 합성수지의 경우는 유전가열에 의한 발열이 곤란하여 그 접착기술로 사용할 수 없다는 큰 단점이 있다. 특히 현재 세계적인 신발. 가방제조업체 등 합성수지를 사용하는 산업전반에 일어나고 있는 PVC등 비환경친화적 합성수지 소재의 사용규제로 인하여 환경친화적 합성수지 소재인 PE, EVA, PP 등의 사용이 요구되는데, 이러한 환경친화적 합성수지 소재는 유전손실이 낮아 고주파 유전가열방식을 사용할 수 없으므로 이러한 소재의 접착이 가능한 새로운 기술개발이 요구되고 있다.However, the bonding method by the high frequency dielectric heating has a big disadvantage that synthetic resin having low dielectric loss cannot be used as the bonding technique because it is difficult to generate heat by dielectric heating. Especially the current global shoes. Due to restrictions on the use of non-environmentally-friendly synthetic resin materials, such as PVC, which are occurring throughout the industry that uses synthetic resins, such as bag manufacturers, the use of environmentally-friendly synthetic resin materials such as PE, EVA, and PP is required. As low frequency dielectric heating method cannot be used, new technology development that can bond these materials is required.

또한 고주파 유전가열방식은 10 MHz 정도의 고주파를 요하기 때문에 고주파에 노출되는 작업자는 그 건강을 크게 해치게 되고, 고주파의 영향으로 인해 라디오·TV·조명기기 등 주변 전자기기의 전자파 장애가 발생하며, 고주파 유전가열장치의 핵심부품인 진공관의 수명이 길지 못하여 고가의 부품교체비용이 요구되는 등의 문제점을 안고 있다.In addition, the high frequency dielectric heating method requires a high frequency of about 10 MHz, and the workers exposed to the high frequency harm the health greatly, and the electromagnetic interference of surrounding electronic devices such as radio, TV, and lighting equipment occurs due to the high frequency. The lifetime of the vacuum tube, which is a core part of the dielectric heating device, has a problem such that an expensive part replacement cost is required.

따라서 본 발명은 PE, EVA, PP 등 환경친화적 소재의 순간 접착이 가능하면서도 기존의 유전가열방식에서 제기되는 고주파 사용으로 인한 상기의 각종 문제점을 해결할 수 있는 새로운 합성수지 접착기술을 개발하는데 그 목적이 있다.Therefore, the present invention has the object of developing a new synthetic resin adhesive technology that can solve the above problems caused by the use of high frequency caused by the existing dielectric heating method while being capable of instantaneous bonding of environmentally friendly materials such as PE, EVA, PP. .

상기한 목적을 달성하기 위하여 본 발명은 공지의 고주파 유도가열회로와 상기의 고주파 유도가열회로의 고주파출력에 의하여 금형을 유도가열하는 유도가열 코일부와 상기 유도가열 코일부의 맞은편에 부설되어 합성수지 시트를 가압함과 동시에 상기의 유도가열 코일부에 의해 고주파 유도가열되어 합성수지 시트에 발생된 열을 전달함으로써 합성수지 시트의 접착부를 용융, 접착하는 금형으로 구성된 고주파유도가열기를 이용한 환경친화적 합성수지 시트 접착기를 제공한다.In order to achieve the above object, the present invention is a synthetic resin is placed opposite the induction heating coil unit and the induction heating coil unit for induction heating the mold by the high frequency output of the known high frequency induction heating circuit and the high frequency induction heating circuit. Environmentally friendly synthetic resin sheet adhesive machine using a high frequency induction heater composed of a mold for melting and adhering the adhesive part of the synthetic resin sheet by pressing the sheet and transmitting high frequency induction heating by the induction heating coil part to generate the synthetic resin sheet. To provide.

또한 본 발명은 상기한 고주파 유도가열기를 이용한 환경친화적 합성수지 시트 접착기에 있어서, 상기한 금형은 그 하면에 합성수지시트의 접착부의 기하학적 형상과 일치하는 형상을 가진 가압면을 형성한 것을 특징으로 한다.In addition, the present invention is characterized in that in the environmentally friendly synthetic resin sheet bonding machine using the high frequency induction heater, the mold has a pressing surface having a shape that matches the geometry of the adhesive portion of the synthetic resin sheet.

또한 본 발명은 상기한 고주파유도가열기를 이용한 환경친화적 합성수지 시트 접착기에 있어서, 상기한 가압면에 대응하는 합성수지 시트 접착부의 외주부를 절단할 수 있도록 가압면의 외곽선을 따라 돌출된 절단날을 형성한 것을 특징으로 한다.In addition, the present invention is an environment-friendly synthetic resin sheet bonding machine using the high-frequency induction heater, the cutting edge protruding along the outline of the pressing surface to cut the outer peripheral portion of the synthetic resin sheet adhesive portion corresponding to the pressing surface It is characterized by.

본 발명에 따른 고주파 유도가열기를 이용한 환경친화적 합성수지 시트 접착기의 접착원리 및 바람직한 실시예를 첨부된 도면에 의거하여 상세하게 설명하면 다음과 같다.Referring to the principle and preferred embodiment of the environmentally friendly synthetic resin sheet adhesive machine using a high frequency induction heater according to the present invention in detail based on the accompanying drawings.

먼저 고주파 유도가열의 일반적인 원리를 설명하면 다음과 같다.First, the general principle of high frequency induction heating is explained as follows.

전자유도작용을 이용하여 영구자석 대신 코일에 교류전류를 흘려 교번자속이 발생하게 함으로써 피가열물에 유도전류(와전류)를 흐르게 하면 이 유도전류는 와전류손실에 의해 주울열을 발생시키게 되는데, 이렇게 발생된 열로서 피가열물을 가열하는 것을 고주파 유도가열이라 한다. 주 응용분야는 금속의 열처리, 고주파 용해로, 고주파 용접 및 일반 금속 가열 등에 응용이 되고 있다. 이 고주파 유도가열은 보통 500 KHz 이하의 주파수를 사용하므로 고주파 유전가열방식에서 통상 사용되는 주파수인 10 MHz 보다는 아주 낮은 주파수를 사용할 수 있다는 장점이 있다.When the induced current (eddy current) flows to the heated object by alternating magnetic flux by alternating magnetic flux instead of permanent magnet by using electromagnetic induction action, the induced current generates Joule heat by eddy current loss. Heating the object to be heated by the generated heat is called high frequency induction heating. The main applications are heat treatment of metals, high frequency melting furnaces, high frequency welding and general metal heating. Since the high frequency induction heating uses a frequency of 500 KHz or less, there is an advantage that a frequency lower than 10 MHz, which is a frequency normally used in high frequency dielectric heating, can be used.

그러나, 고주파 유도가열은 유도전류(와전류)가 발생하여 와전류손실에 의하여 열이 발생하는 것이므로 금속과 같은 도체에는 적용이 가능하나 절연물과 같이 저항이 큰 유전체에는 유도전력이 발생되더라도 도체가 아니므로 전류가 흐르지 못하여 유도가열이 불가능하다는 문제가 있다. 따라서 합성수지와 같은 부도체인 유전체의 가열방법으로는 전술한 고주파 유전가열방식이 흔히 사용되고 있다. 그러나, 이 고주파 유전가열방식은 전술한 바와 같이 유전손실이 낮은 PE, PP, EVA등 환경친화적 합성수지의 가열에는 사용할 수 없는 문제가 있다.However, since high frequency induction heating generates induced current (eddy current) and generates heat due to eddy current loss, it can be applied to a conductor such as metal, but it is not a conductor even if induced power is generated in a dielectric having a large resistance such as an insulator. There is a problem that induction heating is not possible because it does not flow. Therefore, the above-described high frequency dielectric heating method is commonly used as a heating method for dielectrics that are insulators such as synthetic resins. However, this high frequency dielectric heating method cannot be used for heating environmentally friendly synthetic resins such as PE, PP, and EVA having low dielectric loss.

이에, 본 발명은 기존의 고주파 유전가열기에 있어서 합성수지 시트의 접착을 위해 합성수지를 가압하는데 필요한 금형이 금속소재이기때문에 고주파 유도가열이 가능하다는 점에 착안하여 금속 가열용 유도가열기를 사용하여 금형을 순간적으로 PE, PP, EVA 등 비유전가열용(환경친화적) 합성수지의 용융점까지 유도가열함으로써 고주파 유전가열이 곤란한 비유전가열용(환경친화적) 합성수지를 접착할 수 있도록 한 것이다.Therefore, the present invention is focused on the fact that the high-frequency induction heating is possible because the mold required to press the synthetic resin for bonding the synthetic resin sheet in the existing high-frequency dielectric heater is capable of high-frequency induction heating, the metal mold using By induction heating up to the melting point of non-dielectric heating (environmentally friendly) synthetic resins such as PE, PP, and EVA, it is possible to bond non-dielectric heating (environmentally friendly) synthetic resin, which is difficult to induce high frequency dielectric heating.

본 발명에 따른 고주파 유도가열기를 이용한 합성수지 시트 접착기의 실시예는 제1도와 같이, 접착할 두 장의 합성수지 시트를 포개어 올려놓는 작업대의 하부에는 유도가열 코일부를 설치하고 작업대의 일측에는 공지의 고주파 유도가열회로를 갖춘 고주파유도가열기를 배설한다. 고주파 유도가열회로는 당업계에서는 공지의 기술이므로 상세히 설명하지 않겠다. 유도가열 코일은 고주파 유도가열기의 출력부에 연결된다. 작업대의 상부에는 금형이 위치하게 되는데 이 금형은 유도가열 코일부에 대응되는 면이 유도가열의 원리에 의하여 합성수지의 용융점까지 순간적으로 가열되는 동시에 합성수지 시트를 가압하면서 그 열을 합성수지 시트에 직접 전달함으로써 합성수지 시트가 가압, 접착되게 된다. 이 때 금형의 가열시간은 약 1~5초 정도에 불과하다.Embodiment of the synthetic resin sheet bonding machine using a high frequency induction heater according to the present invention, as shown in Figure 1, the induction heating coil portion is installed on the lower part of the workbench on which the two sheets of synthetic resin sheets to be bonded are installed and a known high frequency is provided on one side of the workbench. Exposed high frequency induction heater with induction heating circuit. The high frequency induction heating circuit is well known in the art and will not be described in detail. The induction heating coil is connected to the output of the high frequency induction heater. The mold is located on the upper part of the workbench. The mold is heated on the surface corresponding to the induction heating coil part to the melting point of the resin by the principle of induction heating and simultaneously transfers the heat directly to the resin sheet while pressing the resin sheet. The synthetic resin sheet is pressed and adhered. At this time, the heating time of the mold is only about 1 to 5 seconds.

상기 금형은 제2도와 같이 그 내부에 냉각홀을 형성하여 냉각수 또는 냉각용 액체를 순환시킴으로써 순간적으로 가열된 금형을 냉각시키는 동시에 용융점까지 가열된 합성수지 시트가 용융·접착된 후 신속히 냉각될 수 있도록 하는 것이 바람직하다.The mold forms a cooling hole therein as shown in FIG. 2 to circulate the cooling water or the liquid for cooling, thereby cooling the instantaneously heated mold and allowing the synthetic resin sheet heated to the melting point to be quickly cooled after melting and adhering. It is preferable.

또한 금형의 하면에 합성수지 시트 접착부의 기하학적 형상과 일치하는 가압면을 형성하기 위해 금형의 하면에 요철을 형성하는 것이 바람직하다. 예를 들어합성수지 시트 접착면이 링형상일 경우에는 금형의 하면도 링형상의 바닥면만을 남기고 그 이외의 면은 깍아내는 것이다. 이렇게 하면 금형에서 발생된 열이 합성수지 시트 접착부에 집중 전달되어 접착이 효율적으로 진행되고 접착부 이외의 합성수지 시트부분이 접착되는 것을 막을 수 있다.In addition, it is preferable to form irregularities on the lower surface of the mold in order to form a pressing surface that matches the geometry of the synthetic resin sheet adhesive portion on the lower surface of the mold. For example, when the synthetic resin sheet adhesive surface is ring-shaped, the lower surface of the mold also leaves only the ring-shaped bottom surface and scrapes off the other surface. In this way, the heat generated in the mold is transferred to the synthetic resin sheet adhesive portion, thereby adhering efficiently, and preventing the synthetic resin sheet portions other than the adhesive portion from adhering.

또한 합성수지 시트를 특정한 모양으로 절단하여 다른 합성수지 시트 등에 접착시킬 필요가 있을 경우에는 합성수지 시트의 절단 및 접착을 동시에 수행할 수 있도록 금형의 하면에 합성수지 시트의 절단부에 대응하는 위치에 돌출된 절단날을 형성하는 것이 바람직하다.In addition, when it is necessary to cut the synthetic resin sheet into a specific shape and adhere it to another synthetic resin sheet, a cutting blade protruding from the bottom surface of the mold corresponding to the cut portion of the synthetic resin sheet can be simultaneously cut and bonded. It is preferable to form.

이 때 통상적인 제품에 있어서 합성수지 시트 접착부의 외곽선을 따라 절단부를 형성하는 것이 보통이므로 금형의 하면 가압면의 기하학적 형상을 합성수지 시트의 접착부의 형상과 일치시키고 그 가압면의 외곽선을 따라 돌출된 절단날을 형성시키는 것이 바람직하다.In this case, since the cutting part is generally formed along the outline of the adhesive sheet of the resin sheet in a typical product, the cutting edge protrudes along the outline of the pressing surface to match the shape of the pressing surface of the mold with the shape of the adhesive portion of the resin sheet. It is preferable to form

금형의 소재로는 열전달율이 높은 알루미늄 또는 그 합금소재가 바람직하나 유도가열시 알루미늄 소재의 표면가열은 Steel 소재의 표면가열보다 3배 정도 높은 출력과 주파수를 요구하는 관계로 금형 전체를 알루미늄으로 사용할 경우 기계가격의 상승을 초래하는 원인이 된다. 따라서 금형의 상부는 알루미늄 또는 그 합금소재로 하고 금형하부의 가압면은 Steel로 하여 양소재를 폭발접합방법(일명 폭착)으로 접합한 금형을 사용하는 것이 바람직하다. 폭발접합방법은 접합시키려는 소재를 폭발성물질의 폭발력에 의해 순간적으로 접합시키는 방법이다.As the material of the mold, aluminum or alloy material with high heat transfer rate is preferable, but when induction heating, the surface heating of aluminum requires three times higher output and frequency than the surface heating of steel, so when the entire mold is used as aluminum This can cause a rise in machine prices. Therefore, it is preferable to use a mold in which the upper part of the mold is made of aluminum or an alloy material thereof, and the pressurized surface of the lower part of the mold is made of steel, and both materials are joined by an explosion welding method (also known as explosion). Explosion bonding method is a method of instantaneously bonding the material to be bonded by the explosive force of the explosive material.

이상과 같이 본 발명의 일 실시예를 설명하였으나 본 발명의 권리범위는 상기한 실시예에 한정되지 않고 그 기술적 사상의 범위 안에 속하는 다른 실시예들이 모두 포함됨은 물론이다.As described above, one embodiment of the present invention has been described, but the scope of the present invention is not limited to the above-described embodiment, and all other embodiments falling within the scope of the technical idea are of course included.

첫째, 작업환경이 개선된다. 기존의 유전가열 접착 방식의 경우 6 ~ 40 MHz 까지의 고주파 전원을 인가하기 때문에 설비를 사용하는 작업자의 인체에 많은 해를 끼치며 전자파로 인해 주변기기에 전자파 장애가 발생되어 통신 및 전파 장애를 발생시킨다. 반면에 본 발명은 낮은 주파수(50 KHz 이하)를 사용하기 때문에 상기의 피해를 획기적으로 줄일 수 있다.First, the working environment is improved. In the case of the conventional dielectric heating adhesive method, high frequency power of 6 ~ 40 MHz is applied, which causes a lot of harm to the human body of the operator who uses the equipment, and electromagnetic interference causes peripheral devices to cause communication and radio wave interference. On the other hand, since the present invention uses a low frequency (50 KHz or less), the above damage can be greatly reduced.

둘째, 본 발명에 의해 종래 인체 및 환경에 유해한 환경호르몬 및 다이옥신 등이 다량 배출되는 유전가열용 소재(PVC 등)를 대체하여 환경친화적인 합성 수지(PE, PP, EVA 외)를 신발, 가방, 의류, 완구 등 생활용품 전반에 걸쳐 사용할 수 있다.Second, by replacing the dielectric heating material (PVC, etc.) in which a large amount of environmental hormones and dioxins are harmful to the human body and the environment by the present invention, environmentally friendly synthetic resins (PE, PP, EVA, etc.) It can be used throughout clothing and toys.

셋째, 본 발명은 금형면의 발열 시간이 짧아 가열된 금형의 열원을 소재에 신속히 전달함으로써 작업시간이 단축되고 성형 효율이 향상된다.Third, in the present invention, the heat generation time of the mold surface is short, and thus the heat source of the heated mold is quickly transferred to the material, thereby reducing the work time and improving the molding efficiency.
