The present invention relates to an apparatus useful for measuring the temperature of a linear material.

The thickness of fiber materials such as acrylic and rayon is several
It has a thickness of about 10μ to 100μ and is extremely soft. Therefore, even if you try to measure the surface temperature with a contact thermometer, it is difficult to bring the sensing end of the thermometer into stable contact with the textile material being measured, making it impossible to determine the exact temperature. . In particular, in the fiber production process, etc., it is necessary to measure the temperature of continuously moving fiber materials.
In such cases, contact thermometers cannot be used because frictional heat is generated due to contact.

な温度を測定することはできない。 On the other hand, it is possible to measure using an infrared thermometer, which is a non-contact thermometer, but there is a limit to narrowing the measurement field of the infrared thermometer, and it is difficult to measure a thin wire with a diameter of several tens of microns. It's difficult. Further, even if the measurement field of view can be narrowed, it is difficult to capture the object to be measured within the measurement field of view, considering the shake and vibration of the object. Furthermore, when measuring temperature with an infrared thermometer, it is essential to make emissivity correction according to the material, surface condition, etc. of the target object, but it is not clear how much correction to make for thin wires depending on the target object. However, it is difficult to measure the temperature accurately.

次に本実施例の動作を説明する。温度測定対象
物である繊維素材４を、その長手方向が温度基準

ｂのように、画像領域４４との境界が見えなくな
る領域を検出するものである。 The temperature detection signal output by the infrared camera 12 is
It is also output to the image signal processing means 18. The image signal processing means 18 first detects, from among the striped regions 8a to 8c of the temperature reference plate 2, regions in which the thermal image signal level within the same stripe is uniform. That is, the image area 48 of FIG.
As shown in b, an area where the border with the image area 44 is no longer visible is detected.

ことを意味し、両者の材質及び表面状態が同一で
あることからその温度も一致していることを意味
する。 The fact that the boundary between the image area 48b and the image area 44 becomes invisible means that the infrared energy emitted by the area 8b of the temperature reference plate 2 and the fiber material 4 match, and the materials and surface conditions of both are the same. This means that the temperatures are also the same.

and 6c, the average value of the signal levels of the thermal image signals corresponding to 6c is calculated. This average value corresponds to the signal level of the region 8b assuming that it is a black body, and is converted into temperature according to a predetermined relationship.
そして、この換算値に基づいて温度表示信号を
信号線２０に出力する。温度表示手段２２では温
度表示信号に基づいてデイジタル温度表示する。 Then, a temperature display signal is output to the signal line 20 based on this converted value. The temperature display means 22 displays a digital temperature based on the temperature display signal.
なお、本実施例の温度測定対象物は繊維素材で
あるが、金属素線その他の細線も測定できること
はいうまでもない。ただし、その場合は、温度基
準板２の繊維素材領域８ａ〜８ｃに代えて対象物
と同一の材質および表面状態から成る領域を設け
る必要がある。 Although the object to be measured for temperature in this embodiment is a fiber material, it goes without saying that metal wires and other thin wires can also be measured. However, in that case, it is necessary to provide a region made of the same material and surface condition as the object in place of the fiber material regions 8a to 8c of the temperature reference plate 2.
また、対象物４は長手方向に移動しているもの
であつても測定に何ら支障はない。 Further, even if the object 4 is moving in the longitudinal direction, there is no problem in measurement.
さらに、対象物４の温度が温度基準板２の下限
温度と上限温度との間に入るように、ヒータコン
トローラ１０に対して制御信号を出力する機能を
熱画像信号処理手段１８に付加することもでき
る。 Furthermore, a function may be added to the thermal image signal processing means 18 to output a control signal to the heater controller 10 so that the temperature of the object 4 falls between the lower limit temperature and the upper limit temperature of the temperature reference plate 2. can.
また、温度測定精度は、温度基準板２の表面の
温度傾斜を緩くしたり、縞を細く且つ多くしたり

何れか一方を使用した場合であつても、前述の説
明のように第１領域縞に隣接する双方の第２領域
縞における温度の平均値を使用した場合と殆ど同
一の結果が得られる。 Furthermore, temperature measurement accuracy can be improved by making the temperature gradient on the surface of the temperature reference plate 2 gentler or by making the stripes thinner and more numerous. When the stripes are made thinner and more numerous in this way, the first region stripes adjacent to the second region stripes, which have a uniform thermal image signal level, can both be considered to have almost the same temperature.
Even if either one is used, almost the same result can be obtained as in the case where the average value of the temperature in both the second region stripes adjacent to the first region stripe is used as described above.
なお、温度表示手段２２はデイジタル表示に限

まわない。 Note that the temperature display means 22 is not limited to a digital display, and may be a meter display or the like.
