Description

この発明は温度分布検知具、詳しくは一定領域の温度分布を面的な広がりで不可逆的に把握することが出来る温度検知具に関するものである。   The present invention relates to a temperature distribution detector, and more particularly to a temperature detector capable of irreversibly grasping a temperature distribution in a certain region with a planar spread.

各種化学物質や石油系ワックスなどの熱融解物質の熱融解作用を利用し、設定温度超過の事実を発色によって不可逆的に表示する示温ラベルは、検知精度の良さ、設置の容易さ、価格の低廉さなどから各産業分野において広く用いられる。
特願２００７−１９８５４２ なし The temperature indication label that irreversibly displays the fact that the set temperature is exceeded by using the heat melting action of various chemical substances and heat-melting substances such as petroleum-based wax, provides excellent detection accuracy, ease of installation, and low price. For this reason, it is widely used in various industrial fields.
Japanese Patent Application No. 2007-198542 None

従来の熱融解作用を利用した示温ラベルの多くは、貼付されている箇所があらかじめ設定された温度を超過したか否かを表示するだけで、一定領域の温度分布を面的な広がりで把握するのには適していなかった。   Many of the temperature indication labels using the conventional heat melting action can grasp the temperature distribution in a certain area with a wide area just by displaying whether the pasted temperature has exceeded the preset temperature or not. It was not suitable for.

一定領域の温度分布を面的な広がりで把握するものとしては、サーモグラフィー装置があり、各種産業分野において広く使用されているが、これは精密高価な電子装置であり、コスト的にも使用できる範囲は自ずと限られていた。又、不可逆的な検知手段ではなく、結果の解析には専門知識が必要であると共に、非接触で離れた場所から検知するものであるので、狭隘な場所や閉所ではその特性上検知不可能である、と言った問題点も存在していた。   Thermographic devices are widely used in various industrial fields to grasp the temperature distribution in a certain area with a wide area, but this is a precise and expensive electronic device that can be used in terms of cost. Was naturally limited. In addition, it is not an irreversible detection means, it requires expert knowledge to analyze the results, and since it detects from a remote location without contact, it cannot be detected due to its characteristics in a narrow place or closed place. There was also a problem that said there was.

本発明者は、各種産業分野において要望が大きい、一定領域の温度分布を面的な広がりで把握できる手軽な温度検知具を現実すべく研究を行った結果、石油系ワックスなどの熱融解作用を利用してこれを実現した温度分布検知具を開発することに成功し、本発明としてここに提案するものである。   The present inventor has conducted research to realize a simple temperature detector that can grasp the temperature distribution in a certain region with a wide area, which is highly requested in various industrial fields. The present inventors have succeeded in developing a temperature distribution detector that realizes this by using it, and propose it here as the present invention.

あらかじめ設定された任意の温度で融解して透明になる熱融解物質を粉末状に粉砕した粉状熱融解物質と任意の色彩を有する粉状の着色物質と粘ちょう剤とを溶剤中に分散せしめた示温剤を用い、基板上に異る温度で異る色の発色を行う数種類の示温部を相互に隣接させて狭い間隔で繰り返しスポット状に形成せしめることにより、上記課題を解決した。
又、あらかじめ設定された任意の温度で融解して透明になる熱融解物質を粉末状に粉砕した粉状熱融解物質と粘ちょう剤とを溶剤中に分散せしめた、設定温度がそれぞれ異なる数種の示温剤を、基板上に相互に隣接して狭い間隔かつ所望のパターンで繰り返しスポット状に形成されている数種のそれぞれ色彩の異なった着色部の上面に、これを覆う様に、各着色部の色と設定温度とを一致させて塗布し、基板上に異なる温度で異なる色の発色を行う数種の示温部を繰り返し形成せしめることにより、上記課題を解決した。 Disperse in a solvent a powdery heat-melting material obtained by pulverizing a heat-melting material that becomes transparent when melted at an arbitrary preset temperature, a powdered coloring material having an arbitrary color, and a thickening agent. The above-mentioned problem was solved by using a temperature indicating agent and repeatedly forming a plurality of temperature indicating portions that develop different colors at different temperatures on a substrate in a spot-like manner adjacent to each other.
In addition, several kinds of different set temperatures are prepared by dispersing a powdery heat-melting substance obtained by melting a transparent heat-melting substance at an arbitrary preset temperature and a thickener in a solvent. Each of the coloring agents is coated on the upper surface of several colored portions of different colors, which are repeatedly formed in the form of spots in a desired pattern repeatedly with a narrow spacing adjacent to each other on the substrate. The above-mentioned problems were solved by applying the color of the part and the set temperature so as to repeatedly form several temperature indicating parts that develop different colors at different temperatures on the substrate.

この温度分布検知具を温度分布を検知しようとする場所に設置しておくと、それぞれの示温部は設定温度に応じてそれぞれ異なった色で発色し、基板上に色彩模様が形成される。
従って、これらの色彩模様を見ることによって基板上の温度分布を面的広がりで二次元的に検出することが出来る。なお、この色彩模様は不可逆的に形成されるので、設定温度超過後に、温度が低下したとしても消えることはない。
この様に、一定領域の温度分布を正確かつ手軽に知ることが出来、極めて高い実用性を有する。 If this temperature distribution detector is installed in a place where the temperature distribution is to be detected, each temperature indicating portion develops a different color depending on the set temperature, and a color pattern is formed on the substrate.
Therefore, the temperature distribution on the substrate can be detected two-dimensionally in a surface area by viewing these color patterns. Since this color pattern is irreversibly formed, it will not disappear even if the temperature drops after the set temperature is exceeded.
In this way, the temperature distribution in a certain region can be accurately and easily known, and it has extremely high practicality.

基板上に、異る温度で異る色で発色する数種類の示温部を、相互に隣接させて狭い間隔で繰り返しスポット状に形成せしめた点に最大の特徴が存する。   The greatest feature lies in that several types of temperature indicating portions that are colored in different colors at different temperatures are formed on the substrate in a spot shape repeatedly adjacent to each other at narrow intervals.

図１はこの発明に係る温度分布検知具の実施例１の平面図、図２はその要部の拡大平面図である。
図中１は、紙やプラスチック板等からなるシート状をした基板であり、その裏面には粘着層が形成されている。そして、この基板１の表面には示温剤を塗布することにより、異なる温度で異なる色彩で発色する数種類の示温部２ａ、２ｂ、２ｃが、狭い間隔で相互に隣接して繰り返しスポット状に形成されている。
なお、精度の高い検知を行う為には、示温部２ａ、２ｂ、２ｃの大きさをなるべく小さくすると共に、これら示温部２ａ、２ｂ、２ｃ相互間の間隔をなるべく狭くし、配置密度を高くすることが肝要である。 FIG. 1 is a plan view of Embodiment 1 of a temperature distribution detector according to the present invention, and FIG. 2 is an enlarged plan view of a main part thereof.
In the figure, reference numeral 1 denotes a sheet-like substrate made of paper, a plastic plate or the like, and an adhesive layer is formed on the back surface thereof. Then, by applying a temperature indicating agent on the surface of the substrate 1, several types of temperature indicating portions 2a, 2b, 2c that develop colors in different colors at different temperatures are repeatedly formed adjacent to each other at narrow intervals in a spot shape. ing.
In order to perform highly accurate detection, the size of the temperature indicating portions 2a, 2b, and 2c is made as small as possible, and the space between the temperature indicating portions 2a, 2b, and 2c is made as narrow as possible to increase the arrangement density. It is important.

なお、この実施例１においては、示温部２ａは７０℃、示温部２ｂは７５℃、示温部２ｃは８０℃の設定温度で、それぞれ赤、青、緑に発色する様にしたが、示温部２は必ずしも３種類に限る必要はなく、２種類あるいは４種類以上でもよく、又発色する際の色彩も、赤、青、緑に限る必要はないことはもちろんである。   In Example 1, the temperature indicating portion 2a is set to 70 ° C., the temperature indicating portion 2b is set to 75 ° C., and the temperature indicating portion 2c is set to 80 ° C., respectively. 2 is not necessarily limited to three types, and may be two types or four or more types, and it is needless to say that the colors used for color development need not be limited to red, blue, and green.

又、その形成パターンも、図２に示すものの様に、示温部２ａ、２ｂ、２ｃを三角形状に配置するだけではなく、図３に示すものの様に直列状に繰り返してもよく、そのパターンは図示のものに限定されないことはもちろんである。   In addition, the formation pattern is not only arranged in a triangular shape as shown in FIG. 2, but may be repeated in series as shown in FIG. Of course, the present invention is not limited to the illustrated one.

示温部２ａ、２ｂ、２ｃを構成する示温剤は、あらかじめ設定された任意の温度で融解して透明になる熱融解物質を粉末状に粉砕した粉状熱融解物質と、任意の色彩を有する粉状の着色物質と、粘ちょう剤とを溶剤中に分散させたものであり、本件出願人が特願２００７−１９８５４２として提案ずみのものであり、示温剤自体が発色性を有しているので、基板１上に形成される示温部２ａ、２ｂ、２ｃの大きさを小さくし、その配置密度を高めることが可能となっている。
又、この際に用いる熱融解物質としては、耐水性や食品安全性の見地から、石油系ワックスは最も好ましい。 The temperature indicating agents constituting the temperature indicating portions 2a, 2b, and 2c are a powdered heat-melting material obtained by pulverizing a heat-melting material that is melted and transparent at an arbitrary preset temperature, and a powder having an arbitrary color. In the present invention, the present coloring matter and a thickener are dispersed in a solvent, which the applicant of the present application has already proposed as Japanese Patent Application No. 2007-198542, and the temperature-indicating agent itself has color developability. The size of the temperature indicating portions 2a, 2b and 2c formed on the substrate 1 can be reduced and the arrangement density thereof can be increased.
In addition, as the heat melting substance used in this case, petroleum wax is most preferable from the viewpoint of water resistance and food safety.

この実施例１は上記の通りの構成を有するものであり、この温度分布検知具を温度検知を行おうとする場所に設置しておくと、たとえば、８０℃以上に温度が上昇した部分では全ての示温部２ａ、２ｂ、２ｃが、７５℃以上８０℃未満の部分では示温部２ａと２ｂが、７０℃以上７５℃未満の部分では示温部２ａのみがそれぞれ発色し、それに応じて赤、青、緑及びこれらの混合色が基板１上に色彩模様として形成される。   Example 1 has the configuration as described above. If this temperature distribution detector is installed in a place where temperature detection is to be performed, for example, in a portion where the temperature has risen to 80 ° C. or higher, When the temperature indicating portions 2a, 2b, and 2c are 75 ° C. or higher and lower than 80 ° C., the temperature indicating portions 2a and 2b are colored, and when the temperature is 70 ° C. or higher and lower than 75 ° C., only the temperature indicating portion 2a is colored. Green and a mixed color thereof are formed on the substrate 1 as a color pattern.

従って、これらの色彩模様を見ることによって基板１上の温度分布を面的広がりで二次元的に検出することが出来る。なお、この色彩模様は不可逆的に形成されているので、設定温度超過後に、温度が低下したとしても消えることはない。   Therefore, the temperature distribution on the substrate 1 can be detected two-dimensionally with a surface spread by viewing these color patterns. Since this color pattern is irreversibly formed, it will not disappear even if the temperature drops after the set temperature is exceeded.

図４はこの発明に係る温度分布検知具の実施例２の製造途中の状況を示すその要部の拡大平面図、図５はその完成した状況の要部の拡大平面図である。
図中１は、紙やプラスチック板等からなるシート状をした基板であり、実施例１と同様に、その裏面には粘着層が形成されている。そして、この基板１の表面には塗料を塗布することにより、図４に示す様に、異なる色彩の数種の着色部３ａ、３ｂ、３ｃが、狭い間隔で相互に隣接して繰り返しスポット状に形成されている。
なお、精度の高い検知を行う為には、着色部３ａ、３ｂ、３ｃの大きさをなるべく小さくすると共に、これら着色部３ａ、３ｂ、３ｃ相互間の間隔をなるべく狭くし、配置密度を高くすることが肝要であり、各種印刷技術を用いることにより、基板１上に精細に形成することが可能である。
そして、これら着色部３ａ、３ｂ、３ｃの上面には、これを覆う様に、あらかじめ設定された任意の温度で融解して透明になる熱融解物質を粉末状に粉砕した粉状熱融解物質と粘ちょう剤とを溶剤中に分散せしめた、設定温度がそれぞれ異なる数種の示温剤が、前記各着色部３ａ、３ｂ、３ｃと設定温度が一致する様に塗布され、図５に示す様に、基板１上に異なる温度で異なる色の発色を行う数種の示温部２ａ’、２ｂ’、２ｃ’が繰り返し形成されている。
示温部２ａ’、２ｂ’、２ｃ’を構成する示温剤自体は、本件出願人が特願２００４−２０８３１１において提案済みのものであり、あらかじめ設定された任意の温度で融解して透明になる熱融解物質を粉末状に粉砕した粉状熱融解物質と粘ちょう剤とを溶剤中に分散させたものであり、融解前は白濁した不透明状態を呈している。
又、この際に用いる熱融解物質としては、実施例１と同様、耐水性や食品安全性の見地から、石油系ワックスは最も好ましい。 FIG. 4 is an enlarged plan view of an essential part showing a state in the middle of manufacturing of the temperature distribution detector according to the second embodiment of the present invention, and FIG. 5 is an enlarged plan view of an essential part in the completed state.
In the figure, reference numeral 1 denotes a sheet-like substrate made of paper, a plastic plate or the like, and an adhesive layer is formed on the back surface thereof as in the first embodiment. Then, by applying paint on the surface of the substrate 1, as shown in FIG. 4, several colored portions 3a, 3b, 3c of different colors are repeatedly adjacent to each other at a narrow interval in a spot shape. Is formed.
In order to perform highly accurate detection, the size of the colored portions 3a, 3b, and 3c is made as small as possible, and the space between the colored portions 3a, 3b, and 3c is made as narrow as possible to increase the arrangement density. Therefore, it is possible to form finely on the substrate 1 by using various printing techniques.
And on the upper surface of these colored parts 3a, 3b, 3c, a powdery heat-melting substance obtained by pulverizing a heat-melting substance that melts and becomes transparent at an arbitrary preset temperature so as to cover it. Several temperature indicating agents having different set temperatures dispersed in a solvent are applied so that the set temperatures coincide with the colored portions 3a, 3b, 3c, as shown in FIG. On the substrate 1, several temperature indicating portions 2a ′, 2b ′, 2c ′ that develop different colors at different temperatures are repeatedly formed.
The temperature indicating agents constituting the temperature indicating portions 2a ′, 2b ′ and 2c ′ have been proposed by the present applicant in Japanese Patent Application No. 2004-208311, and are heat that becomes melted and transparent at an arbitrary preset temperature. A powdery hot-melting material obtained by pulverizing a melting material into a powder and a thickener are dispersed in a solvent, and it is clouded and opaque before melting.
Further, as the heat melting substance used in this case, as in Example 1, petroleum wax is most preferable from the viewpoint of water resistance and food safety.

なお、この実施例２においては、着色部３ａは赤、着色部３ｂは青、着色部３ｃは緑の色彩となっており、それぞれ融解温度が７０℃、７５℃、８０℃に設定されている示温剤がその上に塗布されているが、着色部３の色彩は、必ずしも３種類に限る必要はなく、２種類あるいは４種類以上でもよく、又、その色彩も、赤、青、緑に限る必要はないことはもちろんである。   In Example 2, the colored portion 3a is red, the colored portion 3b is blue, and the colored portion 3c is green, and the melting temperatures are set to 70 ° C., 75 ° C., and 80 ° C., respectively. Although the temperature indicating agent is applied thereon, the color of the colored portion 3 is not necessarily limited to three, and may be two or four or more, and the colors are limited to red, blue, and green. Of course it is not necessary.

又、その形成パターンも、図５に示すものの様に、示温部２ａ’、２ｂ’、２ｃ’を三角形状に配置するだけではなく、図３に示すものの様に直列状に繰り返してもよく、そのパターンは図示のものに限定されないことはもちろんである。   Also, the formation pattern is not only arranged in a triangular shape as shown in FIG. 5, but may be repeated in series as shown in FIG. Of course, the pattern is not limited to that shown in the figure.

この実施例２も、実施例１と同様、温度検知を行おうとする場所に設置しておくと、設定温度超過の際に、それまで白濁した不透明状態の示温剤が融解して透明になる現象により、たとえば、８０℃以上に温度が上昇した部分では全ての示温部２ａ’、２ｂ’、２ｃ’が、７５℃以上８０℃未満の部分では示温部２ａ’と２ｂ’が、７０℃以上７５℃未満の部分では示温部２ａ’のみがそれぞれ発色し、それに応じて赤、青、緑及びこれらの混合色が基板１上に色彩模様として形成される。   Similarly to Example 1, in Example 2, when it is installed in a place where temperature detection is to be performed, when the set temperature is exceeded, the opaque temperature indicating agent that has become cloudy until then melts and becomes transparent. Thus, for example, all the temperature indicating portions 2a ′, 2b ′, 2c ′ are at the portion where the temperature has risen to 80 ° C. or higher, and the temperature indicating portions 2a ′ and 2b ′ are at 70 ° C. or higher at 75 ° C. Only the temperature indicating portion 2a ′ develops color at a temperature lower than 0 ° C., and red, blue, green, and a mixed color thereof are formed as a color pattern on the substrate 1 accordingly.

この実施例２においては、基板１上に着色部３が直接形成されているので、各種印刷技術を用いて極めて小面積の着色部３を多数精細に形成することが可能で、基板１上により多くの示温部２’を設け、温度分布の測定精度をより一層向上させることが可能である。又、着色部３の上面に感温剤を塗布しているので、温度検知の際の発色が鮮やかであるというすぐれた特徴を有する。   In Example 2, since the colored portion 3 is directly formed on the substrate 1, it is possible to finely form a large number of colored portions 3 having a very small area by using various printing techniques. Many temperature indicating portions 2 'can be provided to further improve the measurement accuracy of the temperature distribution. In addition, since the temperature sensitive agent is applied to the upper surface of the colored portion 3, it has an excellent feature that the color development at the time of temperature detection is vivid.

食品加工、半導体製造をはじめ、各種産業分野において利用可能である。   It can be used in various industrial fields including food processing and semiconductor manufacturing.
