た。 An object being heated by a near-infrared heating device that heats polymer films, resins, etc. or bakes paint using a near-infrared heater that has a heating element housed in a glass body such as a glass bulb or glass tube. It is necessary to measure the temperature of the object and control the power supplied to the near-infrared heater to optimally heat the object. Especially when the object is moving, it is effective to measure the radiant energy from the object without contact. However, the radiant heat from the near-infrared heater enters the radiation thermometer either directly or after being reflected by an object, making it very difficult to accurately measure the temperature of the object.

ある。 FIG. 1 is a block diagram showing an embodiment of this invention. 1 is a moving object such as a film, 21, 22, 23, 24, 25 are each
Near-infrared heaters 210 to 250 are located on both sides of the object 1 and heat the object 1, and each has a heating element housed in a glass body such as a glass bulb or glass tube made of glass, quartz, etc. Reflection plates 211 to 251 with mirror surfaces located on the opposite side of the object 1 of the near-infrared heaters 210 to 250
It is composed of 3, a filter or the like is provided in front of the near-infrared heaters 210 to 250 to measure the temperature of the object 1 in order to use the opaque wavelength range of the glass body as the measurement wavelength, and apply radiant energy to the detection element. Radiation thermometer with incident radiation, 4
is an indicator that indicates the temperature measured by the radiation thermometer 3.

温度計のフイルタでカツトする。 Here, the filter provided in the radiation thermometer 3 is a near-infrared heater 210 to 210 as shown in FIG. 2A.
For the spectral transmittance of the glass body of 250, Fig. 2B
The measurement wavelength is defined as a wavelength range of 4 to 5 μm or more that is opaque to the glass body. In other words, the radiant energy emitted from the heating element passes through the glass body and heats the object.
The radiation thermometer's filter cuts off the energy of the wavelength that passes through this glass body.

０からの放射の影響を受けることがない。 The object 1 is heated by the near-infrared heaters 210 to 250, and its surface temperature is measured by the radiation thermometer 3 in a non-contact manner. At this time, near-infrared heating
Since the radiation thermometer 3 measures the temperature of the object 1 in a wavelength band other than the spectral transmittance of the glass body of the heaters 210 to 250, the near infrared heaters 210 to 25
It is not affected by radiation from 0.
