Description

本発明は、 熱媒体通流ローラ、詳しくは熱媒体通流路に関するものである。   The present invention relates to a heat medium flow roller, and more particularly to a heat medium flow path.

樹脂フィルムなどの処理物をローラに掛け、ローラに当接して通過する間に処理物を所定の温度に加熱したり、高温の処理物を所定の温度にまで奪熱することが行われている。加熱処理する場合、ローラは加熱処理に必要な温度に高められ、奪熱処理する場合、処理物からの奪熱作用によってローラ自体の温度が上昇するので、処理物の冷却に適応する温度までローラを冷却する。いずれの場合も熱をローラに移送する熱媒体を必要とし、その熱媒体として流体たとえば油が使用されている場合がある。   A treatment object such as a resin film is placed on a roller, and the treatment object is heated to a predetermined temperature while passing through the roller, or the high temperature treatment object is deprived to a predetermined temperature. . When heat treatment is performed, the roller is heated to a temperature required for the heat treatment. When heat treatment is performed, the temperature of the roller itself increases due to heat removal from the processed material. Cooling. In either case, a heat medium that transfers heat to the roller is required, and a fluid such as oil may be used as the heat medium.

図４は、このような熱媒体通流ローラの一例の概略構成を示すもので、図４において、１はローラ本体を構成するロールシェル、２は図示しないモータにより回転してロールシェル１を回転する回転駆動軸、３は中子、４は熱媒体通流路である。ロールシェル１内を通流する熱媒体の通流路は、ロールシェル１の内周面と中子３の外周面との間に空隙部を形成し、この空隙部に回転駆動軸２の中空孔２ａから流入する熱媒体を通流する。ロールシェル１内を通流した熱媒体は、この例では反対側の回転駆動軸２の中空孔から流出する。
特開２００４−１１６５３８号公報 FIG. 4 shows a schematic configuration of an example of such a heat medium flow roller. In FIG. 4, 1 is a roll shell constituting the roller body, 2 is rotated by a motor (not shown), and the roll shell 1 is rotated. Rotation drive shaft, 3 is a core, and 4 is a heat medium passage. The flow path of the heat medium flowing through the roll shell 1 forms a gap between the inner circumferential surface of the roll shell 1 and the outer circumferential surface of the core 3, and the hollow of the rotary drive shaft 2 is formed in this gap. The heat medium flowing in from the hole 2a flows. In this example, the heat medium flowing through the roll shell 1 flows out from the hollow hole of the opposite rotation drive shaft 2.

このように構成された従来のローラでは、基本的にロールシェル１の小さい内周面の熱をロールシェル１の大きい外周面へ伝達する構成であるため、負荷熱量が大きい場合には、ロールシェル１の温度が低下し、所望の温度まで処理物を加熱または冷却することができず、これを行うにはロールシェル１の径を大きくするか、ローラの回転速度を遅くすることで、ロールシェル１と接触する時間を延ばす必要があるといった問題があった。   In the conventional roller configured as described above, since the heat of the small inner peripheral surface of the roll shell 1 is basically transmitted to the large outer peripheral surface of the roll shell 1, when the amount of heat applied is large, the roll shell The temperature of 1 is lowered, and the processed product cannot be heated or cooled to a desired temperature. To do this, the diameter of the roll shell 1 is increased or the rotation speed of the roller is decreased, whereby the roll shell There was a problem that it was necessary to extend the time for contact with 1.

本発明が解決しようとする課題は、ローラ内を通流する熱媒体とローラの接触面を広げ、ロールシェルの径を大きくしたり、ローラの回転速度を遅くすることなく、処理物を所望の温度まで加熱または冷却することができ、斯かる問題を解消する点にある。 The problem to be solved by the present invention is to widen the contact surface between the heat transfer medium flowing through the roller and the roller, increase the diameter of the roll shell, and reduce the rotation speed of the roller, so that the processed material can be obtained as desired. It can be heated or cooled to a temperature, which eliminates such a problem.

本発明は、熱媒体をローラ内部に通流して前記ローラを所定の温度に保持してなる熱媒体通流ローラにおいて、前記ローラの肉厚内部に、周方向に沿ってローラの一方の端部から他方の端部に伸びる熱媒体を通流する螺旋孔を形成してなることを主な特徴とする。 The present invention relates to a heat medium flow roller in which a heat medium is flowed into a roller to keep the roller at a predetermined temperature, and one end portion of the roller is disposed along the circumferential direction inside the wall thickness of the roller. The main feature is to form a spiral hole through which a heat medium extending from one end to the other end flows.

本発明では、ローラの表面側の肉厚内部に螺旋孔を形成し、その螺旋孔に熱媒体を通流するので、伝熱面積が広げられ処理物の負荷熱量にかかわらず、所望の温度まで加熱または冷却することができる。   In the present invention, a spiral hole is formed in the wall thickness on the surface side of the roller, and a heat medium is passed through the spiral hole, so that the heat transfer area is widened and the desired temperature is reached regardless of the heat load of the processed material. Can be heated or cooled.

ローラ内を通流する熱媒体とローラの接触面を広げ、ロールシェルの径を大きくしたり、ローラの回転速度を遅くすることなく、処理物を所望の温度まで加熱または冷却することができるようにする目的を、ローラの表面側の肉厚内部に、周方向に沿ってローラの一方の端部から他方の端部に伸びる熱媒体を通流する螺旋孔を形成することにより実現した。 The contact surface between the heat medium flowing through the roller and the roller is widened, and the workpiece can be heated or cooled to a desired temperature without increasing the diameter of the roll shell or slowing down the rotation speed of the roller. The purpose of achieving the above is realized by forming a spiral hole through which the heat medium extending from one end of the roller to the other end along the circumferential direction is formed inside the thickness on the surface side of the roller.

図１は、本発明の実施例に係る熱媒体通流ローラの断面図、図２は図１に示す熱媒体通流ローラのロールシェルの展開平面図である。 図１および図２において、１１はローラ本体を構成するロールシェル、１２は回転駆動軸、１３はロータリジョイント、１４は熱媒体排出通流管、１５はシールドリングである。熱媒体排出通流管１４は回転駆動軸１２の中空内に配置され、ロールシェル１１内に位置する端部はシールドリング１５により蜜詮されており、他端はロータリジョイント１３に連結されている。   FIG. 1 is a cross-sectional view of a heat medium flow roller according to an embodiment of the present invention, and FIG. 2 is a developed plan view of a roll shell of the heat medium flow roller shown in FIG. 1 and 2, 11 is a roll shell constituting the roller body, 12 is a rotary drive shaft, 13 is a rotary joint, 14 is a heat medium discharge flow pipe, and 15 is a shield ring. The heat medium discharge flow pipe 14 is disposed in the hollow of the rotary drive shaft 12, the end located in the roll shell 11 is honeyed by the shield ring 15, and the other end is connected to the rotary joint 13. .

ロールシェル１１には、その表面側の肉厚内部に連通する螺旋状の孔１１ａが、ロールシェル１１の一端から他端にまたがって形成され、螺旋状の孔１１ａの一端はロータリジョイント１３に連結した回転駆動軸１２の中空内部と連通し、他端は回転駆動軸１２の中空孔を経由して熱媒体排出通流管１４と連通している。このような螺旋状の孔１１ａは図２に示すように、矩形状の金属平板１１に斜め方向に一定のピッチで複数のドリル孔１１ａを明け、一端側のドリル孔１１aの開口１１ｃと隣接のドリル孔１１ａの他端側の開口１１ｄを合わせて円筒状に形成し、合わせ目を溶接して作成される。   The roll shell 11 is formed with a spiral hole 11 a that communicates with the inside of the wall on the surface side, extending from one end of the roll shell 11 to the other end, and one end of the spiral hole 11 a is connected to the rotary joint 13. The rotation drive shaft 12 communicates with the hollow interior, and the other end communicates with the heat medium discharge flow pipe 14 through the hollow hole of the rotation drive shaft 12. As shown in FIG. 2, such a spiral hole 11a has a plurality of drill holes 11a formed at a constant pitch in an oblique direction on a rectangular metal flat plate 11, and is adjacent to the opening 11c of the drill hole 11a on one end side. The opening 11d on the other end side of the drill hole 11a is formed into a cylindrical shape and welded to form a joint.

このように構成した熱媒体通流ローラは、ロータリジョイント１３から流入した熱媒体を回転駆動軸１２の中空内部を経由して螺旋状の孔１１ａ内に導入し、熱媒体孔１１ａ内を経由した後、回転駆動軸１２の中空内および熱媒体排出通流管１４を経てロータリジョイント１３から流出する。螺旋状の孔１１ａ内を通流する熱媒体によりローラを加熱または冷却する。   The heat medium flow roller configured as described above introduces the heat medium flowing in from the rotary joint 13 into the spiral hole 11a through the hollow interior of the rotary drive shaft 12, and passes through the heat medium hole 11a. After that, it flows out from the rotary joint 13 through the hollow of the rotary drive shaft 12 and the heat medium discharge flow pipe 14. The roller is heated or cooled by a heat medium flowing through the spiral hole 11a.

このように熱媒体を通流する通流路をロールシェル１１の肉厚内で螺旋状に構成すると、たとえば直径１０ｍｍのドリル孔がピッチ２０ｍｍで設けると、任意の２０ｍｍ幅における単一流体伝熱面積は、１０×３．１４＝３１．４となり、中子とロールシェルの内周面の間に２０ｍｍ幅分の螺旋状の通流路を形成した場合よりも１．５７倍の伝熱面積を得ることができる。 When the flow path through which the heat medium flows is formed in a spiral shape within the thickness of the roll shell 11, for example, when drill holes having a diameter of 10 mm are provided at a pitch of 20 mm, a single fluid heat transfer in an arbitrary 20 mm width is possible. The area is 10 × 3.14 = 31.4, and the heat transfer area is 1.57 times larger than the case where a spiral flow path of 20 mm width is formed between the core and the inner peripheral surface of the roll shell. Can be obtained.

図３は、本発明の他の実施例に係る熱媒体通流ローラの断面図である。なお、図１に示す熱媒体通流ローラと対応する部分には同一の符号を付し、ここではその部分の詳細な説明は省略する。図１に示す熱媒体通流ローラと異なる点は、ロールシェル１１の肉厚内に気液二相の熱媒体を封入するジャケット室１１ｂを設けた点であり、このようにジャケット室１１ｂを設けるとロールシェル１１の長手方向の表面温度の均一性を得ることができる。   FIG. 3 is a cross-sectional view of a heat medium flow roller according to another embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the part corresponding to the heat carrier flow roller shown in FIG. 1, and the detailed description of the part is abbreviate | omitted here.
