Description

本発明は、プリプレグ等の樹脂シート材の硬化度を測定する硬化度測定方法及びそのための測定装置に関するものである。   The present invention relates to a curing degree measuring method for measuring the curing degree of a resin sheet material such as a prepreg and a measuring apparatus therefor.

プリント配線板の製造等に使用されるプリプレグは、エポキシ樹脂等の熱硬化性樹脂を含む組成物をシート状基材（無機又は有機の織布又は不織布）に含浸させ、加熱乾燥することにより樹脂成分を半硬化させることで作製されている。   A prepreg used for manufacturing a printed wiring board is a resin obtained by impregnating a sheet-like base material (inorganic or organic woven or non-woven fabric) with a composition containing a thermosetting resin such as an epoxy resin, and drying by heating. It is made by semi-curing the components.

プリプレグの製造にあたっては、一般的には長尺のシート状基材を連続的に搬送しながら、熱硬化性樹脂組成物に連続的に浸漬するなどしてこの熱硬化性樹脂組成物を含浸させ、更に加熱炉に連続的に通過させることで加熱乾燥して半硬化させ、更に所定寸法に切断することが行われている。   In the production of a prepreg, generally, a long sheet-like base material is continuously conveyed, and the thermosetting resin composition is impregnated by continuously immersing the thermosetting resin composition. Furthermore, it is performed by passing it continuously through a heating furnace to heat-dry and semi-harden it, and then cut it into a predetermined size.

このようなプリプレグの製造過程においては、長尺のシート状基材を連続的に搬送している間にシート状基材への熱硬化性樹脂組成物の含浸量が変化した場合、原料の性質が変動した場合、シート状基材の品質に変動が生じた場合等には、製造されたプリプレグに樹脂の硬化度の不均一が生じるおそれがある。このような不均一が生じると、プリプレグを用いて製造されるプリント配線板等の製品の品質にも影響が及ぶおそれがある。   In such a prepreg manufacturing process, when the amount of impregnation of the thermosetting resin composition into the sheet-like substrate is changed while continuously conveying the long sheet-like substrate, the properties of the raw material When there is a change, or when the quality of the sheet-like base material changes, there is a risk that the degree of curing of the resin will be uneven in the manufactured prepreg. When such non-uniformity occurs, the quality of a product such as a printed wiring board manufactured using a prepreg may be affected.

このため、プリプレグを製造する際には、得られたプリプレグにおける樹脂の硬化度を測定することで、プリプレグ中の樹脂の硬化度が均一となっていることを確認する必要がある。   For this reason, when manufacturing a prepreg, it is necessary to confirm that the degree of cure of the resin in the prepreg is uniform by measuring the degree of cure of the resin in the obtained prepreg.

このようなプリプレグの硬化度の測定方法としては、従来、特許文献１に開示されているようなものが提案されている。   As a method for measuring the degree of cure of such a prepreg, a method disclosed in Patent Document 1 has been proposed.

この従来技術では、プリプレグの製造工程において、加熱処理により得られた長尺のプリプレグを連続的に搬送しながら、このプリプレグに対して赤外線を照射し、特定の波長の赤外線吸収量を測定することにより、硬化度を測定している。   In this prior art, in the prepreg manufacturing process, while continuously transporting a long prepreg obtained by heat treatment, the prepreg is irradiated with infrared rays to measure the amount of infrared absorption at a specific wavelength. Thus, the degree of cure is measured.

すなわち、エポキシ樹脂組成物を用いてプリプレグを作製する場合、エポキシ樹脂を含浸した基材を加熱乾燥して半硬化させると、エポキシ樹脂組成物の硬化反応が進行してこの組成物中のエポキシ基の量が減少する。このため、エポキシ基の吸収波長における赤外線吸収量から、プリプレグ中のエポキシ基の量を導出することができ、これにより硬化度を測定することができる。また、併せてプリプレグ中における反応に関与しないメチル基等の吸収波長における赤外線吸収量を求めれば、このメチル基等の吸収波長の赤外線吸収量と、エポキシ基の吸収波長の赤外線吸収量とに基づき、プリプレグ中における硬化反応により消費されたエポキシ基の割合を求めることができ、これによりプリプレグの硬化度を更に正確に導出することができる。ここで、反応に関与するエポキシ樹脂の量のみから硬化度を測定する場合には、プリプレグに生じる厚みの変化や、基材を構成する繊維の粗密に起因して生じる部分的な樹脂量の変化等によって硬化度を正確に測定することは困難となるが、硬化反応に関与するエポキシ基と、硬化反応に関与しないメチル基の量とに基づいて硬化度を測定すれば、プリプレグを構成する樹脂中のエポキシ基の割合に基づいて硬化度を測定することが可能となる。   That is, when preparing a prepreg using an epoxy resin composition, when the base material impregnated with the epoxy resin is dried by heating and semi-cured, the curing reaction of the epoxy resin composition proceeds and the epoxy group in the composition is cured. The amount of decreases. For this reason, the amount of the epoxy group in the prepreg can be derived from the infrared absorption amount at the absorption wavelength of the epoxy group, and thereby the degree of curing can be measured. In addition, if the infrared absorption amount at an absorption wavelength such as a methyl group that does not participate in the reaction in the prepreg is also obtained, the infrared absorption amount at the absorption wavelength such as the methyl group and the infrared absorption amount at the absorption wavelength of the epoxy group are determined. The ratio of the epoxy groups consumed by the curing reaction in the prepreg can be determined, whereby the degree of curing of the prepreg can be derived more accurately. Here, when the degree of cure is measured only from the amount of the epoxy resin involved in the reaction, the change in the thickness that occurs in the prepreg and the partial change in the amount of resin that occurs due to the density of the fibers constituting the substrate It is difficult to accurately measure the degree of cure by, for example, but if the degree of cure is measured based on the epoxy groups involved in the curing reaction and the amount of methyl groups not involved in the curing reaction, the resin constituting the prepreg It becomes possible to measure the degree of cure based on the proportion of the epoxy group therein.

このように特定の官能基に基づく赤外線吸収量を測定するにあたっては、ＦＴ−ＩＲを用いることもできるが、ＦＴ−ＩＲを用いると装置コストが高くなる。また、上記硬化度の測定では測定する吸収波長が特定されている。このため、プリプレグに赤外線を照射するにあたって、特定波長域を選択的に透過させる複数種のフィルタを用いることも行われている。この場合、測定対象の吸収波長に応じたフィルタを順次選択し、このフィルタを透過した赤外線の、プリプレグを透過等した後の強度を測定することにより、所望の吸収波長における赤外線の吸光を簡便な構成で測定することができる。
特表平０８−５１１１０５号公報 Thus, in measuring the infrared absorption amount based on a specific functional group, FT-IR can be used. However, using FT-IR increases the cost of the apparatus. In the measurement of the degree of curing, the absorption wavelength to be measured is specified. For this reason, when irradiating a prepreg with infrared rays, a plurality of types of filters that selectively transmit a specific wavelength region are also used. In this case, a filter corresponding to the absorption wavelength to be measured is sequentially selected, and the intensity of the infrared light transmitted through the filter after being transmitted through the prepreg is measured, whereby the absorption of the infrared light at a desired absorption wavelength can be simplified. It can be measured by configuration.
JP-T-08-511105

しかし、既述のようにプリプレグの製造工程の後段においてプリプレグの硬化度を測定する場合には、プリプレグに赤外線を照射する過程においてプリプレグは連続的に搬送されることとなる。このため、例えばエポキシ基の吸収波長を測定した後、フィルタを交換してメチル基の吸収波長を測定する場合、その間にプリプレグが移動してプリプレグにおける赤外線の照射位置が変わってしまう。この場合、既述のようにプリプレグ中には樹脂量の部分的な変化が生じ得るため、例えば樹脂量の異なる位置でエポキシ基の量とメチル基の量を測定する事態が生じてしまい、硬化度の正確な測定ができなくなるおそれがあった。   However, as described above, when the degree of cure of the prepreg is measured at a later stage of the prepreg manufacturing process, the prepreg is continuously conveyed in the process of irradiating the prepreg with infrared rays. For this reason, for example, when the absorption wavelength of the epoxy group is measured and then the filter is replaced to measure the absorption wavelength of the methyl group, the prepreg moves during that time, and the infrared irradiation position in the prepreg changes. In this case, since a partial change in the amount of resin may occur in the prepreg as described above, for example, a situation occurs in which the amount of epoxy groups and the amount of methyl groups are measured at positions where the amount of resin is different, and curing occurs. There was a risk that accurate measurement could not be performed.

また、このような事態が発生しないように、プリプレグを所望の寸法に切断した後、静置した状態で上記測定を行うことも考えられるが、硬化度測定のための別工程が必要となって生産効率が低下してしまい、またプリプレグの製造後、硬化度の測定までの間にタイムラグが生じてしまい、硬化度に異常をきたした場合に即時に製造工程の点検、調整を行うことができないという問題がある。   In order to prevent such a situation from occurring, it may be possible to perform the above measurement after the prepreg is cut to a desired dimension and then left standing, but a separate process for measuring the degree of curing is required. Production efficiency will decrease, and there will be a time lag between the production of the prepreg and the measurement of the degree of cure, and if the degree of cure is abnormal, inspection and adjustment of the production process cannot be performed immediately. There is a problem.

本発明は上記の点に鑑みて為されたものであり、連続的に搬送されるプリプレグ等の樹脂シート材に対して、複数回に亘って波長域の異なる赤外線を照射することで測定される赤外線の強度に基づいて樹脂シート材の硬化度を測定することができ、且つシート状基材における部分的な樹脂量の変化に影響されることなく正確な硬化度の測定を行うことができる樹脂シート材の硬化度測定方法及びそのための樹脂シート材の硬化度測定装置を提供することを目的とするものである。   The present invention has been made in view of the above points, and is measured by irradiating a resin sheet material such as a prepreg continuously conveyed with infrared rays having different wavelength ranges over a plurality of times. Resin that can measure the degree of cure of a resin sheet material based on the intensity of infrared rays and can accurately measure the degree of cure without being affected by a partial change in the amount of resin in the sheet-like substrate It is an object of the present invention to provide a method for measuring the degree of cure of a sheet material and an apparatus for measuring the degree of cure of a resin sheet material therefor.

請求項１に係る発明によれば、樹脂シート材１を移動させた状態で、樹脂シート材１中の複数の官能基の各吸収波長の波長域の赤外線Ｌを順次照射し、透過光又は反射光の強度を検出して、各吸収波長における赤外線Ｌの強度に基づいて、樹脂シート材１の樹脂の硬化度を導出するにあたり、赤外線Ｌの照射位置を樹脂シート材１の移動に伴って移動させることにより、樹脂シート材１上の同一の領域９に赤外線Ｌが照射されるようにすることで、樹脂シート材１が移動しているにもかかわらず樹脂シート材１上の同一位置における複数の官能基の吸収波長での赤外線Ｌの強度を検出することができ、樹脂シート材１の厚みの変化等による部分的な樹脂量の変化による影響を受けることなく、樹脂シート材１の硬化度を測定することができるものである。   According to the first aspect of the invention, in the state where the resin sheet material 1 is moved, the infrared rays L in the wavelength ranges of the respective absorption wavelengths of the plurality of functional groups in the resin sheet material 1 are sequentially irradiated to transmit or reflect light.

Since it decreases, based on the intensity of the infrared ray L of the absorption wavelength of each of these functional groups, the effect of the partial change in the resin amount in the resin sheet material 1 is further eliminated, and the degree of curing is measured more accurately. It is something that can be done.

In detecting the intensity of light and deriving the degree of curing of the resin of the resin sheet material 1 based on the intensity of the infrared ray L at each absorption wavelength, the infrared irradiation means 2 and the infrared light receiving means 5 are connected to the resin sheet material 1.

The infrared ray L can be irradiated to the same region 9 on the resin sheet material 1 and the wavelength region of the infrared ray L irradiated to the resin sheet material 1 simultaneously with this movement can be changed sequentially.

The degree of cure can be continuously measured for the resin sheet material 1.

請求項７に係る発明によれば、樹脂シート材１における硬化反応に関与しない官能基の量は硬化の前後で変化せず、一方、硬化反応に関与する官能基の量は硬化反応の進行により減少することから、これら各官能基の吸収波長の赤外線Ｌの強度に基づけば、樹脂シート材１における樹脂量の部分的な変化による影響を更に排除して、更に正確に硬化度を測定することができるものである。   According to the invention which concerns on Claim 7, the quantity of the functional group which does not participate in the curing reaction in the resin sheet material 1 does not change before and after curing, while the amount of the functional group which participates in the curing reaction is due to the progress of the curing reaction. Since it decreases, based on the intensity of the infrared ray L of the absorption wavelength of each of these functional groups, the effect of the partial change in the resin amount in the resin sheet material 1 is further eliminated, and the degree of curing is measured more accurately. It is something that can be done.

以下、本発明を実施するための最良の形態について説明する。   Hereinafter, the best mode for carrying out the present invention will be described.

本発明における硬化度の測定対象である樹脂シート材１は、樹脂を含むと共にシート状の形態を有するものであり、特に熱硬化性樹脂組成物のワニスをシート状基材に含浸させ、加熱乾燥することにより樹脂成分を半硬化させて得られるプリプレグを挙げることができる。前記シート状基材としては、無機又は有機の織布又は不織布を挙げることができる。その他、樹脂を含みシート状の形態を有するものであれば、本発明を適用し得る。樹脂シート材１がプリプレグである場合における熱硬化性樹脂組成物は、プリプレグの製造に用いられているエポキシ樹脂組成物等の適宜のものを用いることができる。   The resin sheet material 1 to be measured for the degree of cure in the present invention includes a resin and has a sheet-like form. In particular, the sheet-like base material is impregnated with a varnish of a thermosetting resin composition, and is heated and dried. By doing so, a prepreg obtained by semi-curing the resin component can be mentioned. As said sheet-like base material, an inorganic or organic woven fabric or a nonwoven fabric can be mentioned. In addition, the present invention can be applied as long as it contains a resin and has a sheet-like form. As the thermosetting resin composition in the case where the resin sheet material 1 is a prepreg, an appropriate one such as an epoxy resin composition used for manufacturing a prepreg can be used.

樹脂シート材１は枚葉状のものであっても良く、長尺なものでも良い。プリプレグの製造工程においてプリプレグの硬化度を測定する場合には、このプリプレグの製造工程の後段において、枚葉状に切断される前の長尺のプリプレグの硬化度を測定することができる。以下、プリプレグの硬化度を測定する場合を例に挙げて本発明を説明する。   The resin sheet material 1 may be a single wafer or may be long. When the degree of cure of the prepreg is measured in the prepreg manufacturing process, the degree of cure of the long prepreg before being cut into sheets can be measured at a later stage of the prepreg manufacturing process. Hereinafter, the present invention will be described by taking as an example the case of measuring the degree of cure of a prepreg.

樹脂シート材１の硬化度測定装置は、基材移動手段、赤外線照射手段２、赤外線波長選択手段３、赤外線受光手段５及び硬化度導出手段６を具備する。   The apparatus for measuring the degree of cure of the resin sheet material 1 comprises a substrate moving means, an infrared irradiation means 2, an infrared wavelength selection means 3, an infrared light receiving means 5, and a cure degree deriving means 6.

図１及び図２は、硬化度測定装置の第一の実施形態を示す。   1 and 2 show a first embodiment of a curing degree measuring apparatus.

基材移動手段は樹脂シート材１を移動させるものであり、このとき樹脂シート材１はその面方向に沿って移動される。樹脂シート材１が長尺である場合には、基材移動手段はこの樹脂シート材１を長手方向に沿って連続的に搬送する。この基材移動手段は、図示はしないが、例えばプリプレグの製造工程におけるシート状基材やプリプレグを搬送する搬送ロール等にて形成することができる。   The substrate moving means moves the resin sheet material 1, and at this time, the resin sheet material 1 is moved along the surface direction. When the resin sheet material 1 is long, the base material moving means continuously conveys the resin sheet material 1 along the longitudinal direction. Although not shown, this base material moving means can be formed by, for example, a sheet-like base material in a prepreg manufacturing process or a transport roll for transporting the prepreg.

赤外線照射手段２としては、赤外線Ｌをビーム状に照射する適宜の赤外線Ｌ発振器を挙げることができる。赤外線照射手段２は、樹脂シート材１の一面と間隔をあけて対向するように配置し、この樹脂シート材１の一面に向けて赤外線Ｌを照射するように配設することができる。   As the infrared irradiation means 2, an appropriate infrared L oscillator that irradiates the infrared L in a beam shape can be exemplified. The infrared irradiating means 2 can be disposed so as to face one surface of the resin sheet material 1 with a space therebetween, and can be disposed so as to irradiate infrared light L toward one surface of the resin sheet material 1.

赤外線波長選択手段３としては、透過波長域が異なる複数のフィルタ４を具備するものが設けられる。前記フィルタ４としては、特定の赤外線Ｌの特定の波長域を選択的に透過させるバンドパスフィルタ４を挙げることができる。赤外線波長選択手段３は、赤外線照射手段２と樹脂シート材１との間の赤外線Ｌの照射経路上に配設され、この赤外線波長選択手段３は、複数のフィルタ４が樹脂シート材１の移動方向に沿って配列するように支持している。   As the infrared wavelength selection means 3, there is provided one having a plurality of filters 4 having different transmission wavelength ranges. Examples of the filter 4 include a band-pass filter 4 that selectively transmits a specific wavelength region of a specific infrared ray L. The infrared wavelength selection means 3 is disposed on the irradiation path of the infrared L between the infrared irradiation means 2 and the resin sheet material 1, and the infrared wavelength selection means 3 has a plurality of filters 4 that move the resin sheet material 1. It supports so that it may arrange along a direction.

上記フィルタ４としては、測定対象の樹脂シート材１における特定の官能基の吸収波長を選択的に透過するものが設けられる。このとき、樹脂シート材１中における樹脂の硬化反応に関与する官能基（以下、活性官能基という）の吸収波長を中心とした波長域を選択的に透過するフィルタ４と、樹脂の硬化反応に関与しない官能基（以下、不活性官能基という）の吸収波長を中心とした波長域を選択的に透過するフィルタ４を設ける。吸収波長は各官能基の吸光度のピーク値の波長を選択することができる。   As said filter 4, what selectively permeate | transmits the absorption wavelength of the specific functional group in the resin sheet material 1 of a measuring object is provided. At this time, the filter 4 that selectively transmits a wavelength region centered on the absorption wavelength of a functional group (hereinafter referred to as an active functional group) involved in the resin curing reaction in the resin sheet material 1 and the resin curing reaction. A filter 4 that selectively transmits a wavelength region centering on an absorption wavelength of a functional group that does not participate (hereinafter referred to as an inert functional group) is provided. As the absorption wavelength, the wavelength of the absorbance peak value of each functional group can be selected.

この複数のフィルタ４としては、熱硬化性樹脂の樹脂組成を変更した場合にも対応できるように、各種の官能基の吸収波長の波長域を選択的に透過するものを複数設けることができる。このとき同時に測定される官能基についてのフィルタ４は、一列に並んで設けられるようにする。また、同じ列に他の官能基の吸収波長を透過するフィルタ４を併せて設けても良い。また、図示の例ではフィルタ４を二列に亘って設けているが、このようにフィルタ４を複数列設ける場合には、熱硬化性樹脂組成物の組成の変更に応じ、各列には同時に測定される官能基の吸収波長の波長域を選択的に透過するフィルタ４を設けるようにする。   As the plurality of filters 4, a plurality of filters that selectively transmit the wavelength ranges of the absorption wavelengths of various functional groups can be provided so as to cope with the case where the resin composition of the thermosetting resin is changed. At this time, the filters 4 for the functional groups that are simultaneously measured are arranged in a line. Moreover, you may provide the filter 4 which permeate | transmits the absorption wavelength of another functional group in the same row | line | column together. Further, in the illustrated example, the filters 4 are provided in two rows. However, when the filters 4 are provided in a plurality of rows as described above, each row is simultaneously provided in accordance with a change in the composition of the thermosetting resin composition. A filter 4 that selectively transmits the wavelength range of the absorption wavelength of the functional group to be measured is provided.

活性官能基と、不活性官能基とは、樹脂シート材１を形成するために用いる熱硬化性樹脂組成物の組成に依存するが、例えばビスフェノール型エポキシ樹脂やノボラック型エポキシ樹脂等を含むエポキシ樹脂組成物の場合は前者の官能基としてエポキシ基を、後者の官能基としてベンゼン環を挙げることができる。   The active functional group and the inactive functional group depend on the composition of the thermosetting resin composition used for forming the resin sheet material 1, but include, for example, an epoxy resin including a bisphenol type epoxy resin or a novolac type epoxy resin. In the case of a composition, an epoxy group can be mentioned as the former functional group, and a benzene ring can be mentioned as the latter functional group.

赤外線受光手段５は、赤外線Ｌを受光して電気信号に変換する適宜の受光素子にて形成することができる。この赤外線受光手段５は、上記赤外線照射手段２から照射された赤外線Ｌが樹脂シート材１の一面に到達した後、この樹脂シート材１を透過した透過光や、樹脂シート材１で反射された反射光を受光するように設けられる。図１に示す例では赤外線受光手段５は樹脂シート材１の赤外線照射手段２が設けられている側とは反対側の面と対向して、透過光を受光する位置に配設されている。図２に示す例では赤外線受光手段５は樹脂シート材１の赤外線照射手段２が設けられている側と同じ側に、反射光を受光する位置に配設されており、このとき赤外線照射手段２は樹脂シート材１の一面に斜め方向に赤外線Ｌを照射し、この樹脂シート材１の一面側における反射光の軌跡上で赤外線受光手段５が反射光を受光するようになっている。   The infrared light receiving means 5 can be formed by an appropriate light receiving element that receives the infrared light L and converts it into an electrical signal. In this infrared light receiving means 5, after the infrared rays L emitted from the infrared irradiation means 2 reach one surface of the resin sheet material 1, the transmitted light transmitted through the resin sheet material 1 or reflected by the resin sheet material 1. It is provided so as to receive the reflected light. In the example shown in FIG. 1, the infrared light receiving means 5 is disposed at a position for receiving transmitted light, facing the surface of the resin sheet material 1 opposite to the side on which the infrared irradiation means 2 is provided. In the example shown in FIG. 2, the infrared light receiving means 5 is disposed on the same side as the side on which the infrared irradiation means 2 of the resin sheet material 1 is provided at a position for receiving the reflected light. Irradiates one surface of the resin sheet material 1 with an infrared ray L in an oblique direction, and the infrared light receiving means 5 receives the reflected light on the locus of the reflected light on one surface side of the resin sheet material 1.

ここで、樹脂シート材１と赤外線受光手段５との間の赤外線Ｌの経路上には、集光レンズ７を設けることにより、赤外線受光手段５が前記集光レンズ７にて集光された赤外線Ｌを受光して検知できるようにすることが望ましい。この場合、樹脂シート材１を透過又は反射することで赤外線Ｌが不均一に拡散した場合であっても、この拡散した赤外線Ｌを集光して受光することで赤外線Ｌの拡散の影響を低減し、測定結果を平均化して正確な測定を行うことができる。   Here, by providing a condenser lens 7 on the path of the infrared ray L between the resin sheet material 1 and the infrared ray receiver 5, the infrared ray receiver 5 collects the infrared ray collected by the condenser lens 7. It is desirable that L can be received and detected. In this case, even if the infrared rays L are diffused non-uniformly by transmitting or reflecting the resin sheet material 1, the diffused infrared rays L are collected and received to reduce the influence of the diffusion of the infrared rays L. In addition, the measurement results can be averaged to perform accurate measurement.

硬化度導出手段６は、赤外線受光手段５にて生成された電気信号が入力され、この電気信号を演算処理して樹脂シート材１の樹脂の硬化度を導出する。この硬化度導出手段６は、ＣＰＵ、ＲＯＭ、ＲＡＭ等から構成される適宜のマイクロコンピュータで構成することができる。この硬化度導出手段６による硬化度を導出するための処理動作については後述する。   The curing degree deriving unit 6 receives the electrical signal generated by the infrared light receiving unit 5 and calculates the degree of curing of the resin of the resin sheet material 1 by calculating the electrical signal. The degree-of-curing degree derivation means 6 can be composed of an appropriate microcomputer composed of a CPU, ROM, RAM and the like. The processing operation for deriving the degree of cure by the degree of cure deriving means 6 will be described later.

本実施形態では、上記赤外線照射手段２及び赤外線受光手段５の配置位置を移動させる駆動手段が設けられている。駆動手段は適宜のアクチュエータで構成することができる。このとき赤外線照射手段２及び赤外線受光手段５は前記駆動手段により、樹脂シート材１の搬送方向に沿って移動し、且つ、樹脂シート材１の移動と同期して、すなわち樹脂シート材１の移動方向と同一方向に同一速度で、移動可能に形成する。   In the present embodiment, driving means for moving the arrangement positions of the infrared irradiation means 2 and the infrared light receiving means 5 is provided. The driving means can be constituted by an appropriate actuator. At this time, the infrared irradiation means 2 and the infrared light receiving means 5 are moved along the conveying direction of the resin sheet material 1 by the driving means, and in synchronization with the movement of the resin sheet material 1, that is, the movement of the resin sheet material 1. It is formed to be movable at the same speed in the same direction as the direction.

このとき、樹脂シート材１に向けて赤外線Ｌを照射した状態で、樹脂シート材１を移動させると、樹脂シート材１の移動に伴って樹脂シート材１上の赤外線Ｌの到達位置も移動し、結果、赤外線照射手段２及び赤外線受光手段５が基材の移動方向と同一方向に移動している間は、樹脂シート材１上の同一領域９に赤外線Ｌが到達し、その透過光又は反射光が赤外線受光手段５により受光されるようになっている。また、赤外線照射手段２及び赤外線受光手段５が樹脂シート材１の移動方向に移動している間は、赤外線Ｌの軌跡が赤外線波長選択手段３の後端のフィルタ４から前端のフィルタ４まで順次通過するようになっている。ここで、図示のように赤外線波長選択手段３にフィルタ４が二列設けられている場合には、赤外線波長選択手段３は基材の搬送方向と直交する方向に移動可能に形成し、いずれか一方の列のフィルタ４において前記のように赤外線Ｌの軌跡が後端のフィルタ４から前端のフィルタ４まで順次通過するようになっている。また、赤外線照射手段２と赤外線受光手段５は、照射される赤外線Ｌの軌跡が前端のフィルタ４まで到達したら、駆動手段により樹脂シート材１の移動方向と反対方向に移動して初期状態に復帰し、再び駆動手段により樹脂シート材１の移動方向に移動可能となる。   At this time, when the resin sheet material 1 is moved in a state in which the infrared ray L is irradiated toward the resin sheet material 1, the arrival position of the infrared light L on the resin sheet material 1 also moves with the movement of the resin sheet material 1. As a result, while the infrared irradiation means 2 and the infrared light receiving means 5 are moving in the same direction as the movement direction of the base material, the infrared rays L reach the same region 9 on the resin sheet material 1 and the transmitted light or reflection thereof. Light is received by the infrared light receiving means 5. Further, while the infrared irradiation means 2 and the infrared light receiving means 5 are moving in the moving direction of the resin sheet material 1, the locus of the infrared L is sequentially from the rear end filter 4 to the front end filter 4 of the infrared wavelength selection means 3. It has come to pass. Here, when two filters 4 are provided in the infrared wavelength selection means 3 as shown in the figure, the infrared wavelength selection means 3 is formed so as to be movable in a direction orthogonal to the conveyance direction of the substrate. In the filter 4 in one row, the locus of the infrared rays L sequentially passes from the rear end filter 4 to the front end filter 4 as described above. The infrared irradiation means 2 and the infrared light receiving means 5 are moved in the direction opposite to the moving direction of the resin sheet material 1 by the driving means when the locus of the irradiated infrared rays L reaches the filter 4 at the front end to return to the initial state. Then, it can be moved again in the moving direction of the resin sheet material 1 by the driving means.

また、この硬化度測定装置における赤外線照射手段２、赤外線波長選択手段３、赤外線受光手段５、及びこれらの間の赤外線Ｌの経路で構成される光学系の周囲には、カバーを設けることが好ましい。この場合、外乱光の影響を低減して測定誤差の発生を抑制し、正確な測定を行うようにすることができる。   Moreover, it is preferable to provide a cover around the optical system constituted by the infrared irradiation means 2, the infrared wavelength selection means 3, the infrared light receiving means 5, and the infrared ray L route therebetween in this curing degree measuring apparatus. . In this case, it is possible to reduce the influence of disturbance light and suppress the occurrence of measurement errors, so that accurate measurement can be performed.

このように構成される硬化度測定装置の動作を説明する。   The operation of the curing degree measuring apparatus configured as described above will be described.

樹脂シート材１が基材移動手段にて移動している状態で、駆動手段により赤外線照射手段２と赤外線受光手段５とを樹脂シート材１の移動と同期するようにしてこの樹脂シート材１の移動方向へと移動させる。集光レンズ７を設けている場合には、駆動手段によりこの集光レンズ７も同様に移動させる。このとき、赤外線照射手段２は赤外線Ｌを連続的に照射していても良いが、赤外線Ｌの軌跡上に特定のフィルタ４が配置された状態となったときにのみ、赤外線Ｌをパルス状に照射しても良い。前記特定のフィルタ４とは、熱硬化性樹脂組成物中の、活性官能基の吸収波長を含む波長域を選択的に透過するフィルタ４と、不活性官能基の吸収波長を含む波長域を選択的に透過するフィルタ４とを意味する。   In a state where the resin sheet material 1 is moved by the base material moving means, the infrared irradiation means 2 and the infrared light receiving means 5 are synchronized with the movement of the resin sheet material 1 by the driving means. Move in the direction of movement. When the condensing lens 7 is provided, the condensing lens 7 is similarly moved by the driving means. At this time, the infrared irradiation means 2 may continuously irradiate the infrared ray L, but only when the specific filter 4 is placed on the locus of the infrared ray L, the infrared ray L is pulsed. It may be irradiated. The specific filter 4 is a filter 4 that selectively transmits a wavelength range including the absorption wavelength of the active functional group in the thermosetting resin composition, and a wavelength range that includes the absorption wavelength of the inert functional group. Means a filter 4 that is transparently transmitted.

このとき、赤外線受光手段５は、赤外線照射手段２と共に移動しながら、樹脂シート材１を反射した反射光、又は樹脂シート材１を透過した透過光を、受光する。   At this time, the infrared light receiving means 5 receives reflected light reflected from the resin sheet material 1 or transmitted light transmitted through the resin sheet material 1 while moving together with the infrared irradiation means 2.

赤外線受光手段５は、受光した光を電気信号に変換して、硬化度導出手段６に伝達する。硬化度導出手段６は、前記電気信号に基づき、上記各特定のフィルタ４を通過した赤外線Ｌの透過光又は反射光の強度を導出する。   The infrared light receiving means 5 converts the received light into an electrical signal and transmits it to the curing degree deriving means 6. The curing degree deriving means 6 derives the intensity of the transmitted light or reflected light of the infrared light L that has passed through each of the specific filters 4 based on the electrical signal.

このとき、活性官能基の吸収波長を含む波長域を選択的に透過するフィルタ４を透過した赤外線Ｌを樹脂シート材１に照射した場合の、上記透過光又は反射光の強度（以下、活性官能基受光強度という）は、樹脂シート材１中の活性官能基の量に依存する。また、不活性官能基の吸収波長を含む波長域を選択的に透過するフィルタ４を透過した赤外線Ｌを樹脂シート材１に照射した場合の、上記透過光又は反射光の強度（以下、不活性官能基受光強度という）は、樹脂シート材１中の不活性官能基の量に依存する。   At this time, the intensity of the transmitted light or reflected light (hereinafter referred to as the active sensor) when the resin sheet material 1 is irradiated with the infrared ray L that has passed through the filter 4 that selectively transmits the wavelength region including the absorption wavelength of the active functional group. The group received light intensity) depends on the amount of active functional groups in the resin sheet material 1. Further, the intensity of the transmitted light or reflected light (hereinafter referred to as inactive) when the resin sheet material 1 is irradiated with the infrared ray L that has passed through the filter 4 that selectively transmits the wavelength region including the absorption wavelength of the inert functional group. The functional group light-receiving intensity) depends on the amount of the inert functional group in the resin sheet material 1.

ここで、樹脂中の不活性官能基の量は樹脂の硬化反応が進行しても反応の前後で変化はしないが、活性反応基の量は樹脂の硬化反応が進行するのに伴って減少する。このため、樹脂の硬化が進むと不活性官能基の量に対する活性反応基の量の割合が小さくなる。そのため、硬化度導出手段６は、上記活性官能基受光強度と、不活性官能基受光強度に基づいて、硬化度を導出することができる。具体的な硬化度の導出方法は適宜のものとすることができるが、例えば、硬化度導出手段６は、不活性官能基受光強度に対する活性官能基受光強度の比を導出し、この比の値から、予め設定されている不活性官能基受光強度に対する活性官能基受光強度の比と硬化度との間の相関関係を参照して、硬化度を導出することができる。   Here, the amount of the inactive functional group in the resin does not change before and after the reaction even if the curing reaction of the resin proceeds, but the amount of the active reactive group decreases as the curing reaction of the resin proceeds. . For this reason, as the curing of the resin proceeds, the ratio of the amount of active reactive groups to the amount of inactive functional groups decreases. Therefore, the curing degree deriving means 6 can derive the curing degree based on the active functional group light receiving intensity and the inert functional group light receiving intensity. Although a specific method for deriving the degree of cure can be set as appropriate, for example, the degree of cure deriving means 6 derives a ratio of the active functional group received light intensity to the inert functional group received light intensity, and the value of this ratio From the above, the degree of cure can be derived by referring to the correlation between the ratio of the active functional group light-receiving intensity to the preset inert functional group light-receiving intensity and the degree of curing.

不活性官能基受光強度に対する活性官能基受光強度の比と硬化度との間の相関関係は適宜の手法で導出したものを予め硬化度導出手段６に記憶させることができる。例えば予め硬化度をそれぞれ異ならせた複数の樹脂シート材１について、上記と同様にして活性官能基受光強度と不活性官能基受光強度とを測定し、その結果に基づいて、不活性官能基受光強度に対する活性官能基受光強度の比と硬化度との相関関係を表す相関表や関係式を導出しておく。そして、この相関表や関係式を硬化度導出手段６に記憶させておき、これに基づいて樹脂シート材１の硬化度を導出するようにする。   The correlation between the ratio of the active functional group light-receiving intensity to the inactive functional group light-receiving intensity and the degree of curing can be stored in advance in the degree-of-curing degree deriving means 6 as derived from an appropriate technique. For example, the active functional group light receiving intensity and the inert functional group light receiving intensity are measured in the same manner as described above for a plurality of resin sheet materials 1 having different degrees of curing in advance, and based on the results, the light receiving of the inactive functional group is received. A correlation table and a relational expression representing the correlation between the ratio of the active functional group light-receiving intensity to the intensity and the degree of curing are derived. Then, the correlation table and the relational expression are stored in the curing degree deriving means 6 so that the curing degree of the resin sheet material 1 is derived based on this.

図３，４は、硬化度測定装置の第二の実施形態を示す。   3 and 4 show a second embodiment of the curing degree measuring apparatus.

図示の実施形態では、基材移動手段、赤外線照射手段２、赤外線受光手段５及び硬化度導出手段６としては、第一の実施形態と同様のものが設けられている。   In the illustrated embodiment, the substrate moving means, the infrared irradiation means 2, the infrared light receiving means 5, and the curing degree deriving means 6 are the same as those in the first embodiment.

また、赤外線波長選択手段３は、樹脂シート材１の一面に対して直交する方向の回転駆動軸８を有する円盤状に形成され、前記回転駆動軸８を中心とする円周に沿って複数のフィルタ４が支持されている。このフィルタ４は図示の例では回転駆動軸８を中心とする二つの同心円の円周に沿ってそれぞれ列設されている。   The infrared wavelength selection means 3 is formed in a disk shape having a rotation drive shaft 8 in a direction orthogonal to one surface of the resin sheet material 1, and a plurality of infrared wavelength selection means 3 are arranged along a circumference around the rotation drive shaft 8. A filter 4 is supported. In the example shown in the figure, the filters 4 are arranged along the circumference of two concentric circles around the rotation drive shaft 8.

このフィルタ４としては第一の実施形態と同様のものが設けられる。このとき、図示の例では一方の同心円の円周に沿って列設されたフィルタ４と他方の同心円の円周に沿って列設されたフィルタ４とは、それぞれ同時に測定される官能基の吸収波長の波長域を選択的に透過するフィルタ４を設けるようにする。   This filter 4 is the same as that of the first embodiment. At this time, in the example shown in the drawing, the filter 4 arranged along the circumference of one concentric circle and the filter 4 arranged along the circumference of the other concentric circle respectively absorb the functional groups measured simultaneously. A filter 4 that selectively transmits the wavelength range of the wavelength is provided.

この赤外線波長選択手段３は、赤外線照射手段２と樹脂シート材１との間の赤外線Ｌの照射経路に、いずれかのフィルタ４が配置されるように配設される。また、赤外線照射手段２に対する赤外線波長選択手段３の配置位置を変更することで、二つの同心円の円周に沿って列設された各フィルタ４のうち、一方の同心円の円周に沿って配置されたフィルタ４が赤外線Ｌの照射経路に配置された状態と、他方の同心円の円周に沿って配置されたフィルタ４が赤外線Ｌの照射経路に配置された状態とに切り替えることができる。   The infrared wavelength selection means 3 is arranged so that any one of the filters 4 is arranged in the irradiation path of the infrared L between the infrared irradiation means 2 and the resin sheet material 1. Further, by changing the arrangement position of the infrared wavelength selection means 3 with respect to the infrared irradiation means 2, the filters 4 arranged along the circumference of two concentric circles are arranged along the circumference of one concentric circle. It is possible to switch between the state in which the filter 4 is arranged in the irradiation path of the infrared ray L and the state in which the filter 4 arranged along the other concentric circle is arranged in the irradiation path of the infrared ray L.

本実施形態では、上記赤外線照射手段２、赤外線波長選択手段３及び赤外線受光手段５の配置位置を移動させる駆動手段が設けられている。駆動手段は適宜のアクチュエータで構成することができる。このとき赤外線照射手段２、赤外線波長選択手段３及び赤外線受光手段５は前記駆動手段により、樹脂シート材１の搬送方向に沿って移動し、且つ、樹脂シート材１の移動と同期して、すなわち樹脂シート材１の移動方向と同一方向に同一速度で、移動可能に形成する。また、この赤外線波長選択手段３は、前記のように赤外線照射手段２及び赤外線受光手段５と共に移動しながら、回転駆動軸８を中心に一定の角速度で回転駆動するように形成されている。   In the present embodiment, driving means for moving the arrangement positions of the infrared irradiation means 2, the infrared wavelength selection means 3, and the infrared light reception means 5 is provided. The driving means can be constituted by an appropriate actuator. At this time, the infrared irradiation means 2, the infrared wavelength selection means 3, and the infrared light receiving means 5 are moved along the conveying direction of the resin sheet material 1 by the driving means, and are synchronized with the movement of the resin sheet material 1, that is, The resin sheet material 1 is formed to be movable in the same direction as the moving direction at the same speed. Further, the infrared wavelength selection means 3 is formed to rotate at a constant angular velocity around the rotation drive shaft 8 while moving together with the infrared irradiation means 2 and the infrared light receiving means 5 as described above.

このとき、樹脂シート材１に向けて赤外線Ｌを照射した状態で、樹脂シート材１を移動させると、樹脂シート材１の移動に伴って樹脂シート材１上の赤外線Ｌの到達位置も移動し、結果、赤外線照射手段２及び赤外線受光手段５が基材の移動方向と同一方向に移動している間は、樹脂シート材１上の同一領域９に赤外線Ｌが到達し、その透過光又は反射光が赤外線受光手段５により受光されるようになっている。また、この間、赤外線波長選択手段３が回転駆動軸８を中心に一定の角速度で回転駆動することにより、赤外線Ｌの軌跡が赤外線波長選択手段３の一つの円周上にある複数のフィルタ４を順次通過するようになっている。ここで、図示のように赤外線波長選択手段３にフィルタ４が二つの同心円の円周にそれぞれ設けられている場合には、赤外線波長選択手段３の配置位置を既述のように赤外線照射手段２に対して移動させることで、いずれか一方の同心円の円周のフィルタ４において前記のように赤外線Ｌの軌跡がこの同心円の円周上のフィルタ４を順次通過するようになっている。また、赤外線照射手段２、赤外線波長選択手段３及び赤外線受光手段５は、赤外線Ｌの軌跡が一方の同心円の円周上のフィルタ４を全て通過したら、駆動手段により樹脂シート材１の移動方向と反対方向に移動して初期状態に復帰し、再び駆動手段により樹脂シート材１の移動方向に移動可能となる。   At this time, when the resin sheet material 1 is moved in a state in which the infrared ray L is irradiated toward the resin sheet material 1, the arrival position of the infrared light L on the resin sheet material 1 also moves with the movement of the resin sheet material 1. As a result, while the infrared irradiation means 2 and the infrared light receiving means 5 are moving in the same direction as the movement direction of the base material, the infrared rays L reach the same region 9 on the resin sheet material 1 and the transmitted light or reflection thereof. Light is received by the infrared light receiving means 5. Further, during this time, the infrared wavelength selection means 3 is driven to rotate at a constant angular velocity around the rotation drive shaft 8, so that a plurality of filters 4 whose locus of the infrared L is on one circumference of the infrared wavelength selection means 3 can be obtained. Pass through sequentially. Here, when the filter 4 is provided on the circumference of two concentric circles in the infrared wavelength selection means 3 as shown in the figure, the arrangement position of the infrared wavelength selection means 3 is determined as described above. As described above, the locus of the infrared rays L sequentially passes through the filter 4 on the circumference of the concentric circle as described above. Further, the infrared irradiation means 2, the infrared wavelength selection means 3, and the infrared light receiving means 5 are arranged so that the driving direction of the resin sheet material 1 is determined by the driving means when the locus of the infrared rays L passes through the filter 4 on the circumference of one concentric circle. It moves in the opposite direction, returns to the initial state, and can be moved again in the moving direction of the resin sheet material 1 by the driving means.

他の構成は、第一の実施形態と同様とすることができる。   Other configurations can be the same as those of the first embodiment.

このように構成される硬化度測定装置の動作を説明する。   The operation of the curing degree measuring apparatus configured as described above will be described.

樹脂シート材１が基材移動手段にて移動している状態で、駆動手段により赤外線照射手段２、赤外線波長選択手段３及び赤外線受光手段５を樹脂シート材１の移動と同期するようにしてこの樹脂シート材１の移動方向へと移動させると共に、赤外線波長選択手段３を回転駆動させる。このとき、赤外線受光手段５は赤外線Ｌを連続的に照射していても良いが、赤外線Ｌの軌跡上に特定のフィルタ４が配置された状態となったときにのみ、赤外線Ｌをパルス状に照射しても良い。前記特定のフィルタ４とは、熱硬化性樹脂組成物中の、活性官能基の吸収波長を含む波長域を選択的に透過するフィルタ４と、不活性官能基の吸収波長を含む波長域を選択的に透過するフィルタ４とを意味する。   In a state where the resin sheet material 1 is moved by the base material moving means, the driving means causes the infrared irradiation means 2, the infrared wavelength selection means 3 and the infrared light receiving means 5 to synchronize with the movement of the resin sheet material 1. While moving the resin sheet material 1 in the moving direction, the infrared wavelength selection means 3 is driven to rotate. At this time, the infrared light receiving means 5 may continuously irradiate the infrared ray L, but only when the specific filter 4 is placed on the locus of the infrared ray L, the infrared ray L is pulsed. It may be irradiated. The specific filter 4 is a filter 4 that selectively transmits a wavelength range including the absorption wavelength of the active functional group in the thermosetting resin composition, and a wavelength range that includes the absorption wavelength of the inert functional group. Means a filter 4 that is transparently transmitted.

このとき、赤外線受光手段５は、赤外線照射手段２と共に移動しながら、樹脂シート材１を反射した反射光、又は樹脂シート材１を透過した透過光を、受光する。   At this time, the infrared light receiving means 5 receives reflected light reflected from the resin sheet material 1 or transmitted light transmitted through the resin sheet material 1 while moving together with the infrared irradiation means 2.

赤外線受光手段５は、受光した光を電気信号に変換して、硬化度導出手段６に伝達する。硬化度導出手段６は、前記電気信号に基づき、第一の実施形態の場合と同様にして樹脂シート材１の硬化度を測定する。   The infrared light receiving means 5 converts the received light into an electrical signal and transmits it to the curing degree deriving means 6. The curing degree deriving means 6 measures the curing degree of the resin sheet material 1 in the same manner as in the first embodiment based on the electrical signal.

上記各実施形態のようにして樹脂シート材１の硬化度を測定すると、樹脂シート材１に生じる厚みの変化等による部分的な樹脂量の変化などに影響されることなく、樹脂シート材１の硬化度を正確に測定することができる。殊に、樹脂シート材１を移動させながら硬化度を測定するにあたって、樹脂シート材１における赤外線Ｌが照射される領域９を同一の領域９とすることができるため、樹脂シート材１における同一の領域９における活性官能基と不活性官能基の量に基づく硬化度の測定を行うことができ、樹脂シート材１における樹脂量の部分的な変化の影響を著しく排除することができる。   When the degree of cure of the resin sheet material 1 is measured as in each of the above embodiments, the resin sheet material 1 is not affected by a partial change in the resin amount due to a change in thickness or the like generated in the resin sheet material 1. The degree of cure can be accurately measured. In particular, when measuring the degree of cure while moving the resin sheet material 1, the region 9 irradiated with the infrared rays L in the resin sheet material 1 can be the same region 9, and therefore the same in the resin sheet material 1. The degree of cure can be measured based on the amounts of active functional groups and inactive functional groups in the region 9, and the influence of partial changes in the resin amount in the resin sheet material 1 can be remarkably eliminated.

このように硬化度を測定するにあたっては、赤外線照射手段２と赤外線受光手段５（第二の実施形態の場合は更に赤外線波長選択手段３）を樹脂シート材１の移動方向に沿って移動させながら測定を行った後、これらを逆方向に移動させて初期の状態に復帰させ、再び同様に硬化度の測定を行うことができる。このように硬化度の測定を繰り返し行うことにより、樹脂シート材１の硬化度を連続的にモニターすることができ、この硬化度に異常が生じた場合に速やかに樹脂シートの製造工程の点検、調整等を行うことができる。   In measuring the degree of curing in this manner, the infrared irradiation means 2 and the infrared light receiving means 5 (in the case of the second embodiment, further infrared wavelength selection means 3) are moved along the moving direction of the resin sheet material 1. After the measurement, these can be moved in the opposite direction to return to the initial state, and the degree of cure can be measured again in the same manner. By repeatedly measuring the degree of cure in this way, the degree of cure of the resin sheet material 1 can be continuously monitored, and when an abnormality occurs in the degree of cure, the inspection of the resin sheet manufacturing process is promptly performed. Adjustments can be made.

また、このような硬化度測定装置は、定期的に動作検査を行い、必要に応じてメンテナンスを行うことが好ましい。   Moreover, it is preferable that such a degree-of-curing degree measurement apparatus performs an operation | movement inspection regularly and performs a maintenance as needed.

例えば、赤外線照射手段２の光源が劣化した場合には、赤外線受光手段５にて検出される信号のＳ／Ｎ比が悪化するため、この光源の劣化の有無を定期的に検査することが好ましい。この場合、例えば樹脂シート材１が存在しない状態で、赤外線照射手段２から照射される赤外線Ｌを赤外線受光手段５にて受光した場合に検出される受光強度が、基準値（例えば、最低限必要なＳ／Ｎ比を得るために必要とされる受光強度）に満たない場合には、赤外線照射手段２の光源が劣化したものとして、光源の交換等のメンテナンスを行うようにする。   For example, when the light source of the infrared irradiating means 2 deteriorates, the S / N ratio of the signal detected by the infrared light receiving means 5 deteriorates. Therefore, it is preferable to periodically inspect for the deterioration of the light source. . In this case, for example, in the state where the resin sheet material 1 does not exist, the received light intensity detected when the infrared light L irradiated from the infrared light irradiation unit 2 is received by the infrared light reception unit 5 is a reference value (for example, a minimum required). If the received light intensity required for obtaining a high S / N ratio is not satisfied, it is assumed that the light source of the infrared irradiation means 2 has deteriorated, and maintenance such as replacement of the light source is performed.

このとき、例えば赤外線照射手段２から照射される赤外線Ｌを、赤外線波長選択手段３における全てのフィルタ４を順次通過させ、この各フィルタ４を通過した赤外線Ｌを赤外線受光手段５により受光するようにしても良い。この場合、各フィルタ４を通過した赤外線Ｌの受光強度の平均値を導出し、この平均値が、基準値（例えば、最低限必要なＳ／Ｎ比を得るために必要とされる受光強度の平均値）に満たない場合には、赤外線照射手段２の光源が劣化したものとして、光源の交換等のメンテナンスを行うようにしても良い。   At this time, for example, the infrared rays L emitted from the infrared irradiation means 2 are sequentially passed through all the filters 4 in the infrared wavelength selection means 3, and the infrared rays L that have passed through the filters 4 are received by the infrared light receiving means 5. May be. In this case, an average value of the received light intensity of the infrared ray L that has passed through each filter 4 is derived, and this average value is used as a reference value (for example, the received light intensity required to obtain the minimum required S / N ratio). If it is less than the average value), the light source of the infrared irradiation means 2 may be deteriorated, and maintenance such as replacement of the light source may be performed.

また、赤外線波長選択手段３のフィルタ４に汚れが付着した場合には、フィルタ４における赤外線Ｌの透過率が変化し、正確な測定は困難となる。このため、前記フィルタ４の汚れの有無も定期的に検査することが好ましい。この場合、例えば樹脂シートが存在しない状態で、赤外線照射手段２から照射される赤外線Ｌを、赤外線波長選択手段３における全てのフィルタ４を順次通過させ、この各フィルタ４を通過した赤外線Ｌを赤外線受光手段５により受光する。そして、各フィルタ４を通過した赤外線Ｌの受光強度の強度比を導出し、この強度比が、基準値（例えば予め赤外線照射手段２の光源に劣化が生じていない状態で測定された前記強度比）と一致しない場合には、フィルタ４に汚れが付着しているものと判定する。この場合、フィルタ４の清掃や交換等のメンテナンスを行う。   In addition, when dirt is attached to the filter 4 of the infrared wavelength selection means 3, the transmittance of the infrared L in the filter 4 changes, and accurate measurement becomes difficult. For this reason, it is preferable to periodically inspect the filter 4 for contamination. In this case, for example, in the absence of a resin sheet, the infrared rays L emitted from the infrared ray irradiation means 2 are sequentially passed through all the filters 4 in the infrared wavelength selection means 3, and the infrared rays L that have passed through the filters 4 are infrared rays. Light is received by the light receiving means 5. And the intensity ratio of the received light intensity of the infrared ray L that has passed through each filter 4 is derived, and this intensity ratio is the reference value (for example, the intensity ratio measured in advance in a state where the light source of the infrared irradiation means 2 has not deteriorated). ), It is determined that the filter 4 is contaminated. In this case, maintenance such as cleaning and replacement of the filter 4 is performed.
