い部分とでも表面温度に明らかな差異が生ずる。 Cooling rotating rollers are sometimes used to cool resin films, synthetic fiber yarns, etc. This attempts to cool the film, thread, etc. by bringing it into contact with the surface of a rotating roller, but in this case, the surface temperature of the roller is always kept lower than the temperature of the load such as the film, thread, etc. Therefore, a cooling medium such as water or thermal oil is allowed to flow into and out of the roller through a rotary joint provided at the end of the roller. However, in order to cause the cooling medium to flow in and out through the roller ends as described above, it is necessary to flow the cooling medium along the axial direction of the roller. According to such a flow of the cooling medium, even if the cooling medium is at a low temperature at the beginning of the flow, the temperature gradually increases as it receives heat from the rollers during the flow process. Therefore, even if the portion of the surface of the roller that is cooled at the beginning of the flow of the cooling medium is sufficiently cooled, the cooling effect of the portion that is cooled near the end of the flow of the cooling medium is reduced. This causes the surface temperature of the roller to
A gradient may occur along the direction of flow of the cooling medium. Also, there is a clear difference in surface temperature between the parts that are in contact with the load and the parts that are not in contact with the load.

損失も大きいといつた欠点がある。 Furthermore, in a cooling roller having such a configuration, unless the temperature at the entrance of the cooling medium to the roller is sufficiently controlled, the surface temperature of the roller and the temperature of the load to be cooled by this roller cannot be controlled. Therefore, conventionally, the load is first cooled down to a low temperature (for example, room temperature), and then the load is heated by a heating roller whose temperature is sufficiently controlled. However, this method requires rollers for cooling and heating, resulting in a large facility space and a large loss of thermal energy.

The purpose is to ensure control of the temperature distribution.

たことを特徴とする。 This invention provides a jacket chamber in which a gas-liquid two-phase heating medium is enclosed in a thick wall portion of the peripheral wall of the roller body, and uses heat transport due to a phase change of this heating medium to uniformly distribute the surface temperature of the roller body. At the same time, an electromagnetic induction mechanism is installed inside the roller body to provide a heating function, and the cooling medium is used to cool the roller to a temperature lower than the target temperature, and in this state, the roller is heated by the magnetic flux generation mechanism. The present invention is characterized in that the temperature of the roller is controlled to a target temperature by this heating.

である。 A roller equipped with a jacket chamber containing a gas-liquid two-phase heating medium is already well known as a heating roller. This is because an electromagnetic induction mechanism or other suitable heating device is installed inside the roller body, and even if the heating distribution is not uniform, the heat inside the jacket chamber is kept uniform so that the surface temperature distribution of the roller is uniform. Even if the phase change of the medium is repeated and a load is applied to a portion of the surface of the roller, the temperature distribution on the surface of the roller is made uniform in the same way as described above.

の表面温度分布を均一にする。 To explain this further, it is assumed that the heat medium in the jacket chamber is vaporized by the heat of the roller heated by the heating device, and when the surface temperature of the roller decreases, the heat medium that has touched that part The medium is cooled and returns to the liquid phase, providing latent heat of condensation and increasing the surface temperature of the roller. This makes the surface temperature distribution of the roller uniform. However, in this invention, even though a gas-liquid two-phase heating medium is used, as will be described later, the heating medium is always in a liquid phase state due to the cooled rollers, and in this respect, as described above, Its phase state is different from that of the heat medium in the heat roller. When the heat medium in this invention comes into contact with the roller portion whose temperature has increased due to heat from the load, it vaporizes, absorbs latent heat of vaporization from the roller portion, and lowers the temperature. This makes the surface temperature distribution of the roller uniform.

あるということができる。 On the other hand, in a heat roller, the surface temperature distribution of the roller is made uniform by the latent heat of condensation, whereas in this invention, the surface temperature distribution of the roller is made uniform by the latent heat of vaporization. , it can be said that the action of the heating medium to be utilized is exactly the opposite.

In the embodiment shown in FIGS. 1 and 2, reference numeral 1 denotes a roller body, which is equipped with circular shafts 2 and 2A at both ends, and has a bearing 4 interposed between it and a fixed hollow shaft 3. Therefore, it is rotatably supported on the shaft 3. It is then rotated by a suitable external drive source (for example, a motor). The peripheral wall portion 5 of the roller body 1 is composed of an inner cylindrical portion 6 and an outer cylindrical portion 7, and a jacket chamber 8 is constituted by both the cylindrical portions 6 and 7. 9 is enclosed in the jacket chamber 8,

It is leaked from 10B. Both ends are led out to the end side of the shaft 3, and the intermediate portion 10C is led into the interior of the roller body 1, particularly into the lower half, through a hole 3A provided in the peripheral wall of the shaft 3.
In FIG. 1, the intermediate portion 10C of the flow path 10 is reciprocated only once, but in reality, it is preferable to make it reciprocate several times as shown in FIG. Middle part 10C
is the intermediate heat medium 1 housed inside the roller body 1

B is used as an iron core, and an induction coil 1 is placed around its outer circumference.
It is constructed by winding 4. 15
is a conducting wire for energizing the induction coil 14,
This is connected to an AC power source. The relationship between the magnetic flux generation mechanism 13 and the roller body 1 is the same as in a heat roller device, and when the induction coil 14 is excited by an AC power source, the alternating magnetic flux generated thereby causes the intermediate portion 3B of the shaft 3 to After passing in the axial direction, it passes through the peripheral wall portion 5 of the roller body 1 in the axial direction, and returns to the intermediate portion 3B again. This alternating magnetic flux generates an induced current in the peripheral wall portion 5 of the roller body 1, generating heat.

する。 A temperature sensor 16 detects the temperature of the peripheral wall 5 and is embedded within the peripheral wall 5. A lead 17 leads to the temperature sensor 16 and is connected to a slip ring 18 that rotates integrally with the roller body 1. A brush 19 is in sliding contact with the slip ring 18. A voltage generated by the temperature sensor 16 in response to the temperature of the peripheral wall portion 5 is extracted to the outside via a lead 17, a slip ring 18, and a brush 19. The voltage applied to the induction coil 14 is changed in accordance with the temperature detected by the temperature sensor 16 to adjust the temperature of the roller body 1 generated by the magnetic flux generating mechanism 13.

とになる。 In the above configuration, prior to starting the operation of the roller, the induction coil 14 is energized in advance to raise the temperature of the peripheral wall portion 5 of the roller body 1 to a desired temperature.
Also, a cooling medium is allowed to flow through the flow path 10. Under this condition, a load is passed through the roller. That is, the load of the film, thread, etc. to be cooled is brought into sliding contact with or attached to the peripheral wall portion 5 of the roller body 1. The temperature of the load is higher than the temperature of heat generated by the magnetic flux generation mechanism 13 of the peripheral wall portion 5 . Therefore, heat is applied to the peripheral wall portion 5 from the load. The load is cooled by this heat conduction.

つてその接触部分の温度が上昇した場合でも同様
に作用し、温度分布を均一にする。 The amount of heat applied from the load passes through the outer cylinder section 7 and reaches the jacket chamber 8. Jacket compartment 8
The heat medium 9 enclosed therein is normally in a liquid phase. However, due to the heat passing through the outer cylinder part 7, the phase is converted into a gas phase, and at this time, the latent heat of vaporization is taken away from the temperature rising part of the outer cylinder part 7. As a result, the temperature of that portion decreases, and the surface temperature distribution of the roller body 1 becomes uniform. Further, even if the temperature of the contact portion rises due to heat from the load in contact with the roller body 1, the roller body 1 acts in the same manner, making the temperature distribution uniform.

１４による加熱の増加は短時間で可能であり、又
高精度の温度制御も可能である。 The vaporized heat medium comes into contact with the circumferential surface of the inner cylindrical portion 6, where it is cooled and phase-converted to a liquid phase again. At this time, latent heat of condensation is given to the inner cylinder portion 6. The amount of heat in the inner cylindrical portion 6 is transferred to the flow path 10C via the intermediate heat medium 11.
The heat is transferred to the cooling medium inside the roller body 1, and the heat is exhausted to the outside of the roller body 1 by this cooling medium. However, if the amount of heat exhausted through this path is greater than the amount of heat given to the roller body 1 from the load, the temperature of the roller body 1 will drop. The temperature sensor 16 detects this temperature drop.
is detected. Based on this detection, the conditions for energizing the induction coil 14 are changed to increase the amount of induced heat generation in the roller body 1 and restore it to a predetermined temperature. The heating by the induction coil 14 can be increased in a short time, and highly accurate temperature control is also possible.

填物２０も同様の理由により簡単なものでよい。 Note that if the intermediate heat medium 11 is housed in the roller body 1 with the liquid level below the liquid seal 12, it will reach the position of the liquid seal 12 only in the form of droplets. A simple seal structure is sufficient. Furthermore, the liquid-sealing filler 20 inside the shaft 3 may be simple for the same reason.

軸３内に送られる。以下これを繰返す。 In the above configuration, an intermediate heat medium is used to cool the roller body, but when a cooling capacity greater than that provided by this intermediate heat medium is required, it is preferable to circulate the cooling medium directly within the roller body. FIG. 3 shows the structure, in which a plurality of holes 21 are provided at one end of the intermediate portion 3B of the shaft 3, and a plurality of holes 22 are provided at the other end, respectively, radially, that is, from the center of the shaft 3. Provided so as to extend in the direction toward its outer periphery. The cooling medium 23 enters the shaft 3 from one end of the shaft 3, a part of which passes along the axial direction of the shaft 3,
The other part comes out of the shaft 3 through the hole 21, passes between the inner surface of the roller body 1 and the outer peripheral surface of the induction coil 14, and then enters the shaft 3 through the hole 22. The cooling medium 23 that has flowed in this manner is discharged to the outside through a hole 24 provided in the outer end surface of the shaft 3 extending to the outside of the roller. The discharged cooling medium is transferred to the heat exchanger 25
Cooled by Then, it is sent into the shaft 3 again by the pump 26. Repeat this below.

絶縁物の劣化を防止できるので都合がよい。 According to the configurations shown in FIGS. 1 and 3, since the induction coil 14 is in contact with the intermediate heating medium or the cooling medium, the heat generated in the induction coil 14 is cooled by these, so overheating of the induction coil can be eliminated. ,
This is convenient because deterioration of the insulator can be prevented.

The effect is that the surface temperature of the roller body can be controlled with high precision.
