近年來’伴隨例如改變連續材料的種類，要求以短時 严曰，進行輥主體的加熱溫度的變更。另外，在拉伸處理步驟 結束後，從安全衛生的觀點出發，如果輥主體的溫度不下 降到一定溫度以下，則操作者不能從工作現場離開。因此， 需要在盡可能短的時間内冷卻輥主體。 此外’不僅僅把感應發熱輥裝置用於連續材料的加 熱’有時也把感應發熱輥裝置用於冷卻’因此需要 發熱輥裝置具有冷卻功能。 μ 作為使感應發熱輥裝置具有冷卻功能的技術，可以考 . 慮如專利文獻1所示的技術，在輥主體的周壁内，沿中心 軸向在周向上等間隔地設置多個冷卻介質通道，通過使^ 邠介質在該冷卻介質通道内迴圈，從而使輥主體冷卻。飞 但是，為了使冷卻介質在冷卻介質通道内迴圈，泰 通過輥主體或與輥主體一體設置在輥主體端部的軸部^要 頸部），從外部提供冷卻介質。由於輥主體或輛頤部是轉$ 201247031

device, and more particularly to an induction heat generating roller device excellent in cooling performance. [Prior Art] Conventionally, for example, an induction heat generating roller device is used in a continuous heat treatment step of a continuous material such as a sheet of a plastic film, paper, cloth, nonwoven fabric, synthetic fiber, metal foil, or a woven material or a wire (filament) material. The induction heat generating roller device is provided with an induction heat generating mechanism in the rotating roller body, whereby the peripheral wall of the light body is heated by the induced current. In recent years, it has been required to change the heating temperature of the roller body in a short period of time, for example, by changing the type of the continuous material. Further, after the end of the stretching treatment step, from the viewpoint of safety and hygiene, if the temperature of the roller main body does not fall below a certain temperature, the operator cannot leave the work site. Therefore, it is necessary to cool the roller body in the shortest possible time. Furthermore, not only the induction heat generating roller device is used for heating of continuous material, but also the induction heat generating roller device is used for cooling. Therefore, the heat generating roller device is required to have a cooling function. As a technique for causing the induction heat generating roller device to have a cooling function, it is conceivable to provide a plurality of cooling medium passages at equal intervals in the circumferential direction in the circumferential wall of the roller body, as in the technique disclosed in Patent Document 1. The roller body is cooled by recirculating the medium in the cooling medium passage. However, in order to recirculate the cooling medium in the cooling medium passage, the cooling medium is supplied from the outside through the roller main body or the shaft portion which is integrally provided with the roller main body at the end portion of the roller main body. Since the roller body or the stern part is turned $ 201247031, the money mechanical seal is rotated, etc. _ 'Because the sealing mechanism is made of contact, the seal is worn, thermal deterioration and chemical degradation white can avoid cooling Media navigation and other issues. In addition, in order to avoid the need to regularly maintain the dynamic sealing mechanism or the π, in order to maintain or replace the rotating sealing mechanism, the heating roller is placed, resulting in cost for maintenance or replacement. τ止感应立立2: A device for contact sealing mechanism on both sides, as disclosed in Patent Document 2, may consider a device including: a cooling medium introduction mechanism for introducing a cooling medium into the inside of the roller body; and cooling The medium spray mechanism 'sprays the cooling medium introduced by the cooling medium introduction mechanism toward the inner peripheral wall of the grain main body, and vaporizes latent heat (vaporization heat) vaporized by the sprayed cooling medium when it contacts the inner peripheral wall of the roll main body. Come to the cold body. The cooling medium sprayer is provided with a discharge pipe which is disposed to extend from the end of the inner peripheral wall of the roller main body to the other end in the axial direction from the discharge port provided on the side wall of the discharge pipe Spray the cooling medium in a drop. According to the structure, the cooling medium introduction mechanism and the spraying mechanism are provided on the portion of the induction heat-generating mechanism that is held inside the parent body in a stationary state, and the gold is prevented from being exposed and maintained without the need of the rotary sealing mechanism. The trouble of replacement. However, since the apparatus directly sprays the cooling medium on the inner wide wall of the parent body, the impurities contained in the cooling medium or the components which cannot be evaporated are accumulated on the inner peripheral wall of the roller main body. ^In the case of the case where the cooling medium is water, for example, calcium carbonate becomes an impurity and the component which cannot be evaporated is deposited on the inner peripheral wall of the roller body, and the roller body is corroded due to the dissolved chlorine component, thereby causing the Department 6/20 8 201247031 Bit rusty. If the cooling medium accumulates on the inner peripheral wall of the roller body. When oil is used, the thermally decomposed carbides will be piled up in the chemical composition, but they will be thinned out due to corrosion. , the inner part of the inner body of the roll body of the enamel is in addition to the cooling medium spray hole to spray the m cooling medium, so that μ κ passes through the tiny hole of μ; e is blocked by the dust contained in the cold Suspension of the μ 扪 hole, which causes the sprayer heat roller device to replace the discharge pipe. & + must be disassembled, and the sensation of the sensible ΐΓ ΐΓ 发热 发热 发热 发热 发热 发热 发热 发热 发热 发热 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , = the use of the fault and ΤΓ ± the use of the horse 7 辘.
