본 고안은 유도 발열 로울러에 관한 것으로 특히 전자 유도형 발열 자켓을 갖는 로울러에 관한 것이다.The present invention relates to an induction heating roller, and more particularly to a roller having an electromagnetic induction heating jacket.

종래의 발열 로울러에 있어서는 로울러 내부에 발열체로서 전열선을 설치하는 것이므로 열의 분포가 일정치 아니하며, 또 외부로부터 온도제어가 어려운점이 있다.In the conventional heating roller, since the heating wire is provided as a heating element inside the roller, the distribution of heat is not constant, and temperature control from the outside is difficult.

또, 고압의 스팀에 의한 가열 로울러에 있어서는 고압의 스팀 발생장치가 별도로 필요하여 이에 따른 많은 공간의 소요가 필요하므로 설치비에 있어서나 차지 하는 공간에 의해 많은 비용의 부담과 또 이에 따른 에너지의 소비가 대단히 컸다.In addition, in the heating roller by the high pressure steam, a high pressure steam generator is required separately, which requires a lot of space. Therefore, the burden of the cost and the energy consumption due to the space required for installation cost It was very big.

본 고안은 상기와 같은 종래의 결점을 해결키 위하여 상용의 교류전원을 이용하여 로울러 자체내에서 전자적으로 발열토록하며, 또 이를 별도의 제어장치에 의해 설정온도와 온도분포가 일정하도록 하는 유도형 발열 자켓을 갖는 유도 발열 로울러에 관한 것이다.In order to solve the above-mentioned drawbacks, the present invention uses a commercial AC power source to generate heat electronically in the roller itself, and induces heat generation so that the set temperature and temperature distribution are constant by a separate control device. An induction heating roller having a jacket is provided.

이에 따라 모든 산업분야의 제조나 가공용도에 경제적으로 사용할 수 있게 되는 것이다.Accordingly, it can be economically used for manufacturing or processing in all industrial fields.

즉, 본 고안 유도형 발열자켓 로울러는 의류나 식품포장재료, 건축자재, 및 그 내장재 등으로부터 플라스틱 전선이나, 자기(磁氣)튜브에 이르기까지 모든 산업분야에서 제조나 가공용도에 사용될 수 있으며, 또, 상용의 교류전원으로 사용가능하도록 하는 것이므로 종래와 같은 고압스팀 발생장치가 필요하지 않으므로 설치비용이 절감되며, 또 상술한 바와같이 온도분포가 일정하여 제품의 불량품 발생을 최대한으로 줄일수 있도록 하기 위하여 본 고안은 로울러 내부에 코일과 코어로 되는 자속발생기구로서의 유도코일이 조립되어 있어서 코일에 상용의 주파수를 갖는 교류전압을 인가하면 유도코일은 교번자속을 발생하게되고, 이에 따라 유도코일과 동심적으로 위치하는 회전 로울러는 1권회의 전자 유도코일을 형성하는 것이 되어 로울러의 두께 속에 원주 방향의 단락전류가 유기되며, 로울러 원통부 저면에 걸쳐 발열원으로 되어 자기발열하게 되고, 또 로울러에 설치된 자켓은 그 내부에 기액(氣液) 2상(相)의 열매체가 봉입되어 증발과 응축의 주기(사이클)을 끊임없이 되풀이하면서 로울러 표면의 온도 분포를 항상 균일한 열화작용과 함께 이 자켓의 기능에 의해 유도 발열 자켓 로울러로서의 기능을 발휘할 수 있는 유도 발열 로울러를 제공코자하는 것이다.That is, the induction heating jacket roller of the present invention can be used for manufacturing or processing in all industries, from clothing, food packaging materials, building materials, and interior materials thereof to plastic wires and magnetic tubes. In addition, since it can be used as a commercial AC power supply, it does not require a high-pressure steam generator as in the prior art, thereby reducing the installation cost. Also, as described above, the temperature distribution is constant so as to reduce the occurrence of defective products to the maximum. For the purpose of the present invention, an induction coil as a magnetic flux generating mechanism consisting of a coil and a core is assembled inside the roller. When an AC voltage having a commercial frequency is applied to the coil, the induction coil generates an alternating magnetic flux. Rotating rollers that are positioned as an enemy form one winding of electromagnetic induction coils, and the thickness of the rollers A circumferential short-circuit current is induced in it, and it becomes a heat generating source across the bottom of the roller, and self-heats. In addition, the jacket installed on the roller is filled with a gas-liquid two-phase heat medium inside the roller. The purpose of this invention is to provide an induction heating roller that can continuously function as an induction heating jacket roller by the function of this jacket with the uniform deterioration of the temperature distribution of the roller surface while constantly repeating the cycle of condensation.

따라서, 로울러 표면의 온도분포를 항상 고정밀도로 균일화되며, 이와 같은 로울러는 인덕션 히터 교유의 균열화작용과 함께 자켓의 기능에 의해 부하시나 무부하시를 막론하고, 회전속도와 실정온도의 어떠한 급변에 대해서도 신속하게 대응하여 어디까지나 고정밀도의 온도 특성을 갖게 되는 특징이 있게 되는 것이다.Therefore, the temperature distribution on the surface of the roller is always uniformed with high accuracy, and such rollers, along with the cracking action of the induction heater, have a jacket function, regardless of load or no load, regardless of the sudden change in rotational speed and actual temperature. In response to this, there will be a characteristic of having a high-precision temperature characteristic to the last.

이하 본 고안을 실시예의 도면에 따라 상술한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

로울러축(6)에는 코어(10)와 유도코일(2)로 구성되는 자속 발생기구로 구성되어 있으며, 상기 로울러축(6) 양단에는 져널(4)과 기액2상(氣液二相)의 열매체가 주입된 자켓(3)을 원주면에 구성한 로울러(1)가 축지되어 상기한 로울러축(6)을 중심으로 로울러(1)가 회전토록되어 있으며, 상기한 로울러(1)의 양단은 슬립링(9)에 의해 도시하지 않은 좌금에 얹져저 회전하도록되어 있다.The roller shaft (6) is composed of a magnetic flux generating mechanism comprising a core (10) and an induction coil (2). The roller (1) constituting the jacket (3) on the circumferential surface of the heat medium is injected, the roller (1) is rotated around the roller shaft (6), and both ends of the roller (1) are slipped. The ring 9 is mounted on a seat (not shown) to rotate.

또, 상기한 로울러(1) 내부에는 온도센서소자(8)가 설치되어 온도검출용 회전 트랜스(11)에 전기적으로 연결되어 도시하지 않은 온도콘트롤러에 의해 제어되도록 하여서 된 것이다.In addition, the temperature sensor element 8 is installed inside the roller 1 to be electrically connected to the rotation transformer 11 for temperature detection so as to be controlled by a temperature controller (not shown).

상기 도면중 미설명부호 5는 코일서포트로드를 의미하고, 7은 유도코일(2)과 연결되는 전원리드선을 의미한다.In the drawing, reference numeral 5 denotes a coil support rod, and 7 denotes a power lead wire connected to the induction coil 2.

상기와 같은 구성으로 되는 것이므로 슬립링(9)을 통해 도시하지 않은 좌금등에 얹져 놓고 고정시킬 수 있게 되며, 이와 같은 로울러(1)와 로울러(1) 또는 별개의 로울러 사이에 연신이나, 가열 또는 예열 혹은 라미네이트등 열로울러로서 사용할 수가 있게 된다.Since it is configured as described above, it is possible to fix it by placing it on a seat or the like not shown through the slip ring 9, and stretching or heating or preheating between the roller 1 and the roller 1 or a separate roller. Or it can be used as a heat roller, such as a laminate.

즉, 전원 리드선(7)을 통해 상용의 교류전원을 인가하게 되면, 유도코일(2)와 코어(10)로 되는 자속발생기구에서 교번자속이 발생하게 되고, 이에 따라 유도코일(2)과 동심적으로 위치하는 회전로울러(1)는 1권회의 전가유도코일이 형성되는 것이므로 로울러(1)의 두꺼운 속에 원주방향으로 단락전류를 유기시켜서 로울러(1) 원통부 전면이 발열판으로되어 자기 발열하게 된다.That is, when commercial AC power is applied through the power supply lead 7, alternating magnetic flux is generated in the magnetic flux generating mechanism including the induction coil 2 and the core 10, thereby concentric with the induction coil 2. Rotating rollers (1) located in the position of the rotary coil (1) is formed by one winding of the induction coil, so the short circuit current in the circumferential direction in the thick of the roller (1) to the front of the roller (1) cylindrical part is a heating plate to self-heating .

따라서, 자켓(3) 내부에 주입된 기액2상의 열매체는 증발과 응축을 되풀이하면서 로울러(1)의 표면 온도분포를 고르게하는 역할을 하게되며, 이때 온도센서소자(8)는 감지된 온도를 온도검출용 회전트랜스(11)에 보내 도시하지 않은 외부의 온도콘트롤러에 송신하여 일정온도를 유지하도록 전원을 자동으로 제어할 수가 있게 되는 것이다.Therefore, the heat medium of the gas-liquid 2 phase injected into the jacket 3 serves to even out the surface temperature distribution of the roller 1 while repeating evaporation and condensation, and the temperature sensor element 8 measures the detected temperature. The power supply can be automatically controlled to be sent to the detection rotation transformer 11 and transmitted to an external temperature controller (not shown) to maintain a constant temperature.

이때 콘트롤러에 의해 로울러(1)의 회전속도는 물론 미리정해진 온도를 유지함으로서 온도특성을 정밀하게 유지할 수 있는 효과가 있는 실용적인 고안인 것이다.At this time, by maintaining the rotational speed of the roller (1) as well as a predetermined temperature by the controller is a practical design that has the effect of maintaining the temperature characteristics precisely.
