Description
本発明は、熱媒体通流ローラ装置に関するものである。 The present invention relates to a heat medium flow roller device.
従来、例えばプラスチックフィルム、紙、布、不織布、合成繊維、金属箔等のシート材又はウェブ材、線（糸）材等の連続材の連続熱処理工程等には、特許文献１に示すような熱媒体通流ローラ装置がある。 Conventionally, for example, in a continuous heat treatment step of a continuous material such as a sheet material such as a plastic film, paper, cloth, nonwoven fabric, synthetic fiber, and metal foil, a web material, or a wire (thread) material, the heat shown in Patent Document 1 is used. There is a medium flow roller device.
この熱媒体通流ローラ装置は、回転するローラ本体の内部に加熱された例えば油などの流体からなる熱媒体を、加熱装置を介して循環ポンプにより循環通流し、この通流によってローラ本体の表面温度を所定の温度に保持するものである。 This heat medium flow roller device circulates a heat medium made of fluid such as oil heated inside the rotating roller body by a circulation pump through the heating device, and this flow causes the surface of the roller body to flow. The temperature is maintained at a predetermined temperature.
熱媒体通流ローラ装置に用いられる加熱装置としては、例えば特許文献２に示すように、閉磁路鉄心に一次コイルを巻回するとともに、熱媒体が流れる導体管を二次コイルとして螺旋状に巻回したものがある。ここで、導体管は、電気的リアクタンスを低減させて加熱効率を向上させるべく、導体管の外側周面において全ターン部分を、螺旋の軸方向に延びる電気接続部材で溶接等により電気的に接続し、導体管内で短絡回路を形成するように構成されている。そして、この加熱装置は、前記一次コイルに交流電圧を印加して、導体管内に短絡電流を流すことにより、導体管をジュール発熱させて熱媒体を加熱している。 As a heating device used in the heat medium flow roller device, for example, as shown in Patent Document 2, a primary coil is wound around a closed magnetic circuit core, and a conductor tube through which the heat medium flows is spirally wound as a secondary coil. There is something turned. Here, in order to reduce the electrical reactance and improve the heating efficiency, the conductor tube is electrically connected by welding or the like with an electrical connection member extending in the axial direction of the spiral on the outer peripheral surface of the conductor tube. And it is comprised so that a short circuit may be formed in a conductor pipe. In this heating device, an AC voltage is applied to the primary coil to cause a short-circuit current to flow in the conductor tube, thereby heating the heat medium by causing the conductor tube to generate Joule heat.
しかしながら、導体管に電気接続部材が固定されていると、ジュール発熱する導体管が熱変形しようとした際に、大きな応力が発生し、導体管や電気接続部材、あるいは導体管と電気接続部材との固定箇所等に疲労が蓄積したりや破損したりするおそれが生じる。 However, if the electrical connection member is fixed to the conductor tube, a large stress is generated when the Joule-heated conductor tube is about to be thermally deformed, and the conductor tube and the electrical connection member, or the conductor tube and the electrical connection member, There is a risk that fatigue will accumulate or breakage at the fixing points.
一方、熱媒体の加熱効率をさらに向上させることが求められており、そのためには導体管と熱媒体との接触面積を大きくすることが考えられる。導体管の外側周面に電気接続部材を固定する構成であることから、接触面積を簡単に大きくするには、螺旋の軸方向に巻き数を増やす構成が考えられる。 On the other hand, it is required to further improve the heating efficiency of the heat medium. To that end, it is conceivable to increase the contact area between the conductor tube and the heat medium. Since it is the structure which fixes an electrical connection member to the outer peripheral surface of a conductor tube, the structure which increases the number of turns in the axial direction of a spiral can be considered in order to enlarge a contact area easily.
ところが、導体管の巻き数を増やすことによって、導体管の軸方向寸法が大きくなってしまい、それに伴って加熱装置全体の大型化を招いてしまう。また、導体管の巻き数を増やすことによって、導体管と電気接続部材との固定箇所が増えてしまい、導体管や電気接続部材、あるいは導体管と電気接続部材との固定箇所等に疲労が蓄積したりや破損したりするおそれが生じやすくなる。 However, increasing the number of windings of the conductor tube increases the axial dimension of the conductor tube, which leads to an increase in the size of the entire heating device. Also, by increasing the number of windings of the conductor tube, the number of fixing points between the conductor tube and the electrical connection member increases, and fatigue accumulates at the conductor tube, the electrical connection member, or the fixing point between the conductor tube and the electrical connection member. Or the possibility of breakage is likely to occur.
そこで本発明は、上記問題点を解決すべくなされたものであり、熱媒体通流ローラ装置を通流する熱媒体の加熱装置において、導体管を長寿命化するとともに導体管と熱媒体との接触面積を増やして加熱効率を向上することをその主たる課題とするものである。 Accordingly, the present invention has been made to solve the above-described problems. In a heating device for a heat medium that flows through a heat medium flow roller device, the present invention extends the life of the conductor tube and reduces the life of the conductor tube and the heat medium. The main problem is to improve the heating efficiency by increasing the contact area.
すなわち本発明に係る熱媒体通流ローラ装置は、内部に熱媒体が通流する熱媒体通流路が形成されたローラ本体と、前記熱媒体を加熱する加熱装置が設けられ、前記加熱装置で加熱された熱媒体を前記ローラ本体の熱媒体通流路に供給する熱媒体供給路とを備え、前記熱媒体通流路に供給された熱媒体によって前記ローラ本体を加熱し、前記ローラ本体の表面に接触する被処理物を熱処理する熱媒体通流ローラ装置において、前記加熱装置は、前記熱媒体が流れる導体管を電磁誘導により発熱させて前記熱媒体を加熱するものであり、螺旋状に巻回された第１導体管及び第２導体管を備え、前記第１導体管及び前記第２導体管の巻径が互いに異なることにより２層構造とされるとともに、前記第１導体管及び前記第２導体管の巻回方向が互いに異なり、前記第１導体管及び前記第２導体管が、両端部において電気的に接続されるとともに前記熱媒体が通流可能に接続されていることを特徴とする。 That is, the heat medium flow roller device according to the present invention includes a roller body in which a heat medium flow channel through which the heat medium flows is formed, and a heating device that heats the heat medium. A heat medium supply path for supplying a heated heat medium to the heat medium flow path of the roller body, heating the roller body with the heat medium supplied to the heat medium flow path, In the heat medium flow roller device for heat-treating an object to be processed that contacts the surface, the heating device heats the heat medium by generating heat by electromagnetic induction in a conductor tube through which the heat medium flows, and in a spiral shape A first conductor tube and a second conductor tube wound are provided, and the first conductor tube and the second conductor tube have a two-layer structure by different winding diameters, and the first conductor tube and the second conductor tube The winding direction of the second conductor tube is mutually Unlike the first conductor pipe and the second conductor tube, the heat medium is electrically connected at both ends, characterized in that it is connected in a Tsuryu.
この熱媒体通流ローラ装置であれば、巻回方向が互いに逆向きの第１導体管及び第２導体管の一端部同士及び他端部同士を接続しているので、当該第１導体管及び第２導体管の間で短絡回路が形成されるため、電気接続部材を不要にすることができる。これにより、第１導体管及び第２導体管に生じる熱応力を低減して、第１導体管及び第２導体管を長寿命化することができる。
また、第１導体管及び第２導体管からなる２層構造とし、それらの第１導体管及び第２導体管に熱媒体が通流するように構成されているので、導体管を螺旋の軸方向に巻き数を増やすことなく、導体管と熱媒体との接触面積を大きくすることができ、加熱効率を向上することができる。
さらに、二次コイルである導体管の巻き数により、短絡電流及び容量（熱媒体の処理量）の調整が可能となる。
In this heat medium flow roller device, the first conductor tube and the other end of the second conductor tube whose winding directions are opposite to each other are connected to each other. Since a short circuit is formed between the second conductor tubes, an electrical connection member can be eliminated. Thereby, the thermal stress which arises in a 1st conductor tube and a 2nd conductor tube can be reduced, and a 1st conductor tube and a 2nd conductor tube can be extended in life.
In addition, since the two-layer structure including the first conductor tube and the second conductor tube is configured so that the heat medium flows through the first conductor tube and the second conductor tube, the conductor tube is connected to the spiral shaft. The contact area between the conductor tube and the heat medium can be increased without increasing the number of turns in the direction, and the heating efficiency can be improved.
Furthermore, it is possible to adjust the short-circuit current and the capacity (heat medium throughput) by the number of turns of the conductor tube that is the secondary coil.
前記加熱装置は、円筒状鉄心と、前記円筒状鉄心の外部に設けられ、前記円筒状鉄心とともに閉磁路を形成する磁路形成部と、前記円筒状鉄心及び前記磁路形成部の間に設けられ、前記円筒状鉄心の内部に磁束を発生させる誘導コイルとをさらに備え、前記第１導体管及び前記第２導体管が、前記円筒状鉄心及び前記磁路形成部の間に設けられていることが望ましい。
この構成であれば、円筒状鉄心及び磁路形成部の間に、熱源である第１導体管及び第２導体管を配置する構成としているので、第１導体管及び第２導体管から外部に漏れ出る熱を、磁路形成部の内側に閉じ込めることができる。
The heating device is provided between a cylindrical iron core, a magnetic path forming portion that is provided outside the cylindrical iron core and forms a closed magnetic path together with the cylindrical iron core, and the cylindrical iron core and the magnetic path forming portion. And an induction coil for generating magnetic flux inside the cylindrical iron core, wherein the first conductor tube and the second conductor tube are provided between the cylindrical iron core and the magnetic path forming portion. It is desirable.
If it is this structure, since it is set as the structure which arrange | positions the 1st conductor tube and 2nd conductor tube which are heat sources between a cylindrical iron core and a magnetic path formation part, it will be outside from a 1st conductor tube and a 2nd conductor tube. The leaking heat can be confined inside the magnetic path forming part.
