Description

本発明は、容器内で複数種の成分を攪拌・混合して混合液を調製する際、特定成分の混合ミスを検出する混合ミス検出方法及び混合ミス検出システムに関する。   The present invention relates to a mixing error detection method and a mixing error detection system for detecting a mixing error of a specific component when preparing a mixed solution by stirring and mixing a plurality of components in a container.

従来から、長尺のウエブの少なくとも一方の表面に、用途に応じて機能性塗膜を形成することが行われている。このような塗膜形成装置の一例として、ロール状に巻回された長尺のウエブを繰り出し所定速度で搬送させる搬送手段と、搬送するウエブの少なくとも一方の表面に塗工液を塗布して塗膜を形成する塗布手段とを備える塗工装置が広く知られている。塗工装置で塗布される塗工液は、所定容積を有する容器内で複数種の成分を攪拌して混合することにより得られる(例えば特許文献1参照)。   Conventionally, a functional coating film is formed on at least one surface of a long web according to the application. As an example of such a coating film forming apparatus, a long web wound in a roll shape is fed out and conveyed at a predetermined speed, and a coating liquid is applied to at least one surface of the conveyed web. 2. Description of the Related Art A coating apparatus including a coating unit that forms a film is widely known. The coating liquid applied by the coating apparatus is obtained by stirring and mixing a plurality of types of components in a container having a predetermined volume (see, for example, Patent Document 1).

ところで、混合すべき成分を混合し忘れたり、混合量が規定量と大きく相違したりする等の所謂混合ミスが発生する場合がある。このような混合ミスにより得られた混合液を用いて塗膜を形成すると、塗膜が所望の品質特性を発揮しなかったり、品質特性を発揮するものの十分ではなかったりする品質不良が発生する。この場合、製造した製品を廃棄して再度製造し直したり、出荷した製品が返品されたりするという問題がある。しかしながら、一般に混合液は透明であるため、混合液の状態で容易に混合ミスを確認することができなかった。   By the way, there is a case where a so-called mixing error such as forgetting to mix components to be mixed or a mixing amount greatly different from a specified amount may occur. When a coating film is formed using a mixed solution obtained by such a mixing mistake, a quality defect that the coating film does not exhibit desired quality characteristics or exhibits sufficient quality characteristics may occur. In this case, there is a problem that the manufactured product is discarded and manufactured again, or the shipped product is returned. However, since the mixed solution is generally transparent, a mixing error cannot be easily confirmed in the state of the mixed solution.

特開平8−185628号公報JP-A-8-185628

本発明は、以上の点に鑑み、複数種の成分を混合して混合液を調製する際、特定成分の混合ミスを容易に検出できる混合ミス検出方法及び混合ミス検出システムを提供することをその課題とする。   In view of the above, the present invention provides a mixing error detection method and a mixing error detection system capable of easily detecting a mixing error of a specific component when preparing a liquid mixture by mixing a plurality of types of components. Let it be an issue.

上記課題を解決するために、蛍光剤を含有する特定成分を含む複数種の成分を混合して混合液を調製する際、前記特定成分の混合ミスを検出する本発明の混合ミス検出方法は、混合液に紫外光を照射し、混合液の発光度合を基に、前記特定成分の混合ミスを検出することを特徴とする。尚、本発明において、混合ミスとは、混合すべき特定成分を混合し忘れた場合だけでなく、混合量が規定量と相違する場合も含むものとする。また、成分は、液体に限定されず、微粒子のような固体を含むものとする。   In order to solve the above problems, when preparing a mixed solution by mixing a plurality of types of components including a specific component containing a fluorescent agent, the mixing error detection method of the present invention for detecting a mixing error of the specific component is: The mixture liquid is irradiated with ultraviolet light, and the mixing error of the specific component is detected based on the light emission degree of the mixture liquid. In the present invention, the mixing error includes not only the case where the specific component to be mixed is forgotten but also the case where the mixing amount is different from the specified amount. In addition, the component is not limited to a liquid, and includes a solid such as a fine particle.

また、上記課題を解決するために、本発明の混合ミス検出システムは、容器と、容器内で蛍光剤を含有する特定成分を含む複数種の成分を攪拌して混合する撹拌手段と、混合液に紫外光を照射する光照射手段とを有し、混合液の発光度合を基に、前記特定成分の混合ミスを検出することを特徴とする。尚、本発明において、容器には、槽のような大型容器が含まれるものとする。   In order to solve the above-described problem, the mixing error detection system of the present invention includes a container, a stirring unit that stirs and mixes a plurality of types of components including a specific component containing a fluorescent agent in the container, and a mixed liquid. And a light irradiation means for irradiating ultraviolet light, and detecting a mixing error of the specific component based on the light emission degree of the mixed liquid. In the present invention, the container includes a large container such as a tank.

本発明によれば、蛍光剤を含有する特定成分を含む複数種の成分を混合した混合液を調製する際、混合液に紫外光を照射して蛍光剤を発光させる。ここで、混合液が発光しない場合には、混合液中への特定成分の混合し忘れを検出できる。また、特定成分の混合量に応じて混合液中の蛍光剤量が変わるのに伴い混合液の発光度合も変わるため、混合液の発光強度に基づき、特定成分の混合量が規定量と相違することを検出できる。従って、混合液の発光度合(蛍光)を基に混合ミスを容易に検出することができる。   According to this invention, when preparing the liquid mixture which mixed the multiple types of component containing the specific component containing a fluorescent agent, an ultraviolet light is irradiated to a liquid mixture and a fluorescent agent is light-emitted. Here, when the mixed solution does not emit light, it is possible to detect that the specific component is forgotten to be mixed in the mixed solution. In addition, the amount of luminescence of the mixture changes as the amount of the fluorescent agent in the mixture changes according to the amount of the mixture of the specific component. Therefore, the amount of the mixture of the specific component differs from the specified amount based on the emission intensity of the mixture. Can be detected. Therefore, a mixing error can be easily detected based on the light emission degree (fluorescence) of the mixed solution.

以下、図面を参照して、本発明の実施形態の混合ミス検出システム及び混合ミス検出方法を説明する。   Hereinafter, a mixing error detection system and a mixing error detection method according to an embodiment of the present invention will be described with reference to the drawings.

図1に示す混合ミス検出システムMS1は、上部が開放された容器1を備え、この容器1内には容器2a,2b,2cから用途に応じて予め設定された量で複数種の成分(本実施形態では3種の成分A,B,C)が供給される。このように供給される複数種の成分のうちの少なくとも1種の成分(本実施形態では成分A)は蛍光剤を含有しており、以下、蛍光剤を含有する成分Aを「特定成分A」ともいう。また、蓋付きの容器を用いることもできる。上記混合状態確認システムMS1は、容器1内の混合液Lを攪拌する攪拌手段3を備える。攪拌手段3は、プロペラ31と、プロペラ31に連結された回転軸32と、回転軸32を回転駆動する駆動部33とで構成される。攪拌手段3は公知の構造を有するため、ここでは詳細な説明を省略する。攪拌手段3としては、上記構造のものに限定されず、例えば公知のマグネチックスターラーを用いることができる。   A mixing error detection system MS1 shown in FIG. 1 includes a container 1 having an open upper portion, and a plurality of kinds of components (main components) are provided in the container 1 in amounts set in advance according to applications from the containers 2a, 2b, and 2c. In the embodiment, three components A, B, C) are supplied. At least one component (component A in the present embodiment) of the plurality of components supplied in this manner contains a fluorescent agent, and hereinafter, the component A containing the fluorescent agent is referred to as “specific component A”. Also called. A container with a lid can also be used. The mixed state confirmation system MS1 includes stirring means 3 for stirring the mixed liquid L in the container 1. The stirring means 3 includes a propeller 31, a rotating shaft 32 connected to the propeller 31, and a drive unit 33 that rotationally drives the rotating shaft 32. Since the stirring means 3 has a known structure, detailed description thereof is omitted here. The stirring means 3 is not limited to the above structure, and for example, a known magnetic stirrer can be used.

混合ミス検出システムMS1は、混合液Lに紫外光を照射する光照射手段4を更に備える。光照射手段4としては公知の蛍光灯タイプや電球タイプの紫外光ランプを用いることができるため、ここでは詳細な説明を省略する。紫外光ランプ4のタイプや数は、容器1のサイズや形状に応じて適宜設定できる。このような構成を採用することにより、混合液Lを攪拌した後、混合液Lに紫外光を照射することができる。ここで、特定成分Aは蛍光剤を含有するため、特定成分Aを含む混合液Lに紫外光が照射されると、混合液Lは発光する。一方、混合ミスにより特定成分Aを含まない混合液に紫外光が照射されても、混合液Lは発光しない。また、混合液L中の特定成分Aの濃度(蛍光剤の濃度)に応じて発光強度が変化する。このため、混合液Lの蛍光、つまり、混合液L中の蛍光剤の発光度合を目視にて観察することで混合液L中の特定成分Aの混合ミスを確認することができる。   The mixing error detection system MS1 further includes light irradiation means 4 for irradiating the mixed liquid L with ultraviolet light. As the light irradiating means 4, a known fluorescent lamp type or bulb type ultraviolet lamp can be used, and detailed description thereof is omitted here. The type and number of the ultraviolet lamps 4 can be appropriately set according to the size and shape of the container 1. By employ | adopting such a structure, after stirring the liquid mixture L, the liquid mixture L can be irradiated with an ultraviolet light. Here, since the specific component A contains a fluorescent agent, when the mixed liquid L containing the specific component A is irradiated with ultraviolet light, the mixed liquid L emits light. On the other hand, even if ultraviolet light is irradiated to the liquid mixture that does not contain the specific component A due to a mixing error, the liquid mixture L does not emit light. Further, the emission intensity changes according to the concentration of the specific component A in the liquid mixture L (the concentration of the fluorescent agent). For this reason, the mixing mistake of the specific component A in the liquid mixture L can be confirmed by visually observing the fluorescence of the liquid mixture L, that is, the light emission degree of the fluorescent agent in the liquid mixture L.

次に、上記混合ミス検出システムMS1を用い、蛍光剤を含有する成分Aを特定成分Aとし、この特定成分Aと成分Bと成分Cとを混合して混合液Lを調製する際、特定成分Aの混合ミスを検出する場合を例に、本実施形態の混合ミス検出方法を説明する。尚、各種成分としては、高分子樹脂、微粒子、溶媒などを例示することができる。高分子樹脂としては、塩化ビニル・酢酸ビニル共重合体,塩化ビニル,塩化ビニル・アクリロニトリル共重合体,エチレン・酢酸ビニル共重合体等のビニル系共重合体、ポリエチレン,ポリプロピレン等のポリオレフィン樹脂、アクリル樹脂、ポリウレタン樹脂、ポリエーテル樹脂、ポリアミド樹脂、ポリエステル樹脂、ゴム系樹脂、シリコーン系樹脂、フッ素系樹脂を例示することができる。微粒子としては、シリカ、二酸化チタン、アルミナ、炭酸カルシウム、ガラスなどで構成される無機粒子や、ポリメタクリル酸メチル、ポリカーボネイト、ポリスチレン、ポリ塩化ビニルなどで構成される有機粒子を例示することができる。また、溶媒としては、水や、メタノール、エタノール、メチルエチルケトン、アセトン、シクロヘキサノン、ベンゼン、トルエン、キシレン、酢酸エチル等の有機溶剤を例示することができる。また、特定成分Aに含有させる蛍光剤としては、紫外光を吸収して蛍光を発する染料、例えばスチルベン系、ジアミノスチルベン系、キナゾロン系、ペリレン系、クマリン系、ジアミノジフェニル系、イミダゾール系、チアゾール系、オキサゾール系、トリアゾール系、カルバゾール系、ピリジン系、ナフタル酸系、イミダゾロン系、ナフタルイミド系、チオフェン系の染料や、フルオロセイン、チオフラビン、エオシン、ローダミン、テルフェニルなどの蛍光発生剤から選択される少なくとも1種を用いることができる。   Next, when the component A containing the fluorescent agent is used as the specific component A using the mixing error detection system MS1 and the specific component A, the component B, and the component C are mixed to prepare the liquid mixture L, the specific component The method for detecting a mixing error according to this embodiment will be described by taking as an example the case of detecting a mixing error of A. Examples of various components include polymer resins, fine particles, and solvents. Polymer resins include vinyl chloride / vinyl acetate copolymers, vinyl chloride, vinyl chloride / acrylonitrile copolymers, vinyl copolymers such as ethylene / vinyl acetate copolymers, polyolefin resins such as polyethylene and polypropylene, acrylic resins Examples thereof include resins, polyurethane resins, polyether resins, polyamide resins, polyester resins, rubber resins, silicone resins, and fluorine resins. Examples of the fine particles include inorganic particles composed of silica, titanium dioxide, alumina, calcium carbonate, glass, and organic particles composed of polymethyl methacrylate, polycarbonate, polystyrene, polyvinyl chloride, and the like. Examples of the solvent include water and organic solvents such as methanol, ethanol, methyl ethyl ketone, acetone, cyclohexanone, benzene, toluene, xylene, and ethyl acetate. The fluorescent agent contained in the specific component A includes dyes that absorb ultraviolet light and emit fluorescence, such as stilbene, diaminostilbene, quinazolone, perylene, coumarin, diaminodiphenyl, imidazole, and thiazole. , Oxazole series, triazole series, carbazole series, pyridine series, naphthalic acid series, imidazolone series, naphthalimide series, thiophene series dyes and fluorogens such as fluorescein, thioflavine, eosin, rhodamine, terphenyl At least one kind can be used.

先ず、上記3種の成分を容器1内に夫々供給して混合液Lを得る。そして、混合液Lを攪拌手段3により攪拌した後、混合液Lに対して光照射手段4から紫外光を照射する。   First, the above three components are supplied into the container 1 to obtain a mixed solution L. Then, after the mixed solution L is stirred by the stirring unit 3, the mixed solution L is irradiated with ultraviolet light from the light irradiation unit 4.

ここで、混合液Lは蛍光剤を含有するため、紫外光が照射された混合液Lは発光する。然し、何らかの理由により特定成分Aを混合し忘れた場合、混合液Lは蛍光剤を含まないため、混合液Lが発光しない。また、特定成分Aの混合量が規定量と相違する場合、混合液L中の蛍光剤量が変わるため、混合液Lの発光強度が変わる。例えば、混合量が規定量よりも少ない場合には、規定量混合される場合と比較して、蛍光剤の濃度が低くなり、混合液Lの発光強度が低くなる。このため、混合液Lの発光の有無や、混合液Lの発光度合(発光強度や発光輝度)を基に、特定成分Aの混合ミスを目視により検出することができる。そして、混合ミスが検出された場合、混合液Lを次工程(例えば塗工工程)で使用するのを中止することで、品質不良の塗膜が形成されることを防止することができる。   Here, since the liquid mixture L contains a fluorescent agent, the liquid mixture L irradiated with ultraviolet light emits light. However, when the specific component A is forgotten to be mixed for some reason, the mixed solution L does not emit light because the mixed solution L does not contain a fluorescent agent. Further, when the mixing amount of the specific component A is different from the specified amount, the amount of the fluorescent agent in the mixed solution L changes, so that the emission intensity of the mixed solution L changes. For example, when the mixing amount is less than the specified amount, the concentration of the fluorescent agent is lower and the emission intensity of the mixed liquid L is lower than when the specified amount is mixed. For this reason, it is possible to visually detect a mixing error of the specific component A based on the presence or absence of light emission of the liquid mixture L and the light emission degree (light emission intensity or light emission luminance) of the liquid mixture L. And when mixing mistake is detected, it can prevent that the coating film of poor quality is formed by stopping using the liquid mixture L at the next process (for example, coating process).

以上によれば、混合する複数種の成分のうち少なくとも1種の成分に蛍光剤を含有させ、これらの成分を混合した混合液に紫外光を照射するという簡単な方法により、特定成分の混合ミスを検出できる。混合ミスにより得られた混合液を次工程(塗工工程)で使用することが防止できるため、不良品の発生を未然に防ぐことができる。混合液Lとしては、粘着層形成用の塗工液等を挙げることができる。この塗工液の場合、混合する成分としては、粘着主剤、硬化剤、添加剤、溶媒等を挙げることができる。例えば、硬化剤は粘着主剤である樹脂を硬化させるために必要な材料であるが、塗工液を調製する際に硬化剤を混合し忘れた場合、粘着主剤が硬化しないため、塗膜が必要な粘着性能を発揮することができないという不具合が発生するが、後述の実験の如く特定成分Aを硬化剤として本発明を適用すれば、このような不具合を未然に且つ容易に防ぐことができる。   According to the above, it is possible to mix a specific component by a simple method in which a fluorescent agent is contained in at least one component among a plurality of components to be mixed, and ultraviolet light is irradiated to a mixed liquid obtained by mixing these components. Can be detected. Since it can prevent using the liquid mixture obtained by mixing mistake at the next process (coating process), generation | occurrence | production of inferior goods can be prevented beforehand. Examples of the mixed liquid L include a coating liquid for forming an adhesive layer. In the case of this coating liquid, examples of components to be mixed include an adhesive main agent, a curing agent, an additive, and a solvent. For example, the curing agent is a material necessary to cure the resin that is the adhesive main agent, but if you forget to mix the curing agent when preparing the coating liquid, the adhesive main agent does not cure, so a coating film is required However, if the present invention is applied using the specific component A as a curing agent as will be described later, such a problem can be prevented easily and easily.

次に、本発明の効果を確認するため、次の実験を行った。本実験では、3種の成分を混合して混合液たる粘着液を調製する場合の特定成分の混合ミスを検出した。先ず、成分Aを硬化剤(三井化学社製「タケネートA−50」)100質量部(固形分75wt%)とし、この成分Aに蛍光剤(BASFジャパン社製「TINOPAL OB」)1質量部(固形分100wt%)を含有させたものを特定成分Aとした。この特定成分Aを5質量部(固形分75.24wt%)と、成分Bとしての粘着主剤(三井化学社製「タケラックA−1143」)100質量部(固形分60wt%)と、成分Cとしての希釈溶剤(丸善石油化学社製「メチルエチルケトン」)100質量部とをガラス製容器(東静容器社製「MB−450」)1に供給して混合液L1を得た。このとき、混合液L1の総質量に対する蛍光剤の配合量(以下「蛍光剤濃度」という)は、0.0241質量%である。このようにして得た混合液L1を攪拌手段3(プライミクス社製「ホモディスパー2.5型」)により1500rpmで5分間攪拌し、混合液L1に紫外光(66W)を照射し、混合液L1の発光度合を目視にて観察したところ、混合液L1の発光がはっきり確認できた。また、特定成分の混合量を0質量部、0.5質量部、1.0質量部、10.0質量部と変えた点(夫々の蛍光剤濃度は、0質量%、0.00247質量%、0.00493質量%、0.0471質量%である)を除き、上記混合液L1と同様の方法で調製した混合液を夫々L2、L3、L4、L5とした。これらの混合液L2〜L5についても同様に、紫外光を照射してその発光度合を目視にて観察した。混合液L2については発光を確認できなかったが、混合液L3、L4については混合液L1の発光強度よりも低いもののうっすらと発光を確認でき、混合液L5については混合液L1と同様に高強度の発光をはっきり確認できた。これらの結果から、混合液の蛍光を基に、即ち、混合液の発光の有無に基づき特定成分Aの混合の有無を検出できることが判った。さらに、混合液の蛍光の強度に基づき、即ち、混合液の発光度合に基づき特定成分Aの混合量の相違を検出できることが判った。この場合、特定成分Aの混合量と発光強度との関係を予め求めておけば、混合量が規定量と相違することが検出できる。   Next, in order to confirm the effect of the present invention, the following experiment was performed. In this experiment, a mixing error of a specific component was detected when an adhesive liquid as a mixed liquid was prepared by mixing three kinds of components. First, component A is set to 100 parts by mass (solid content 75 wt%) of a curing agent (Mitsui Chemicals “Takenate A-50”), and 1 part by mass of a fluorescent agent (“TINOPAL OB” manufactured by BASF Japan) The one containing a solid content of 100 wt% was designated as specific component A. 5 parts by mass (solid content: 75.24 wt%) of this specific component A, 100 parts by mass (solid content 60 wt%) of adhesive main agent (“Takelac A-1143” manufactured by Mitsui Chemicals, Inc.) as component B, and 100 parts by mass of a dilution solvent (“Methyl ethyl ketone” manufactured by Maruzen Petrochemical Co., Ltd.) was supplied to a glass container (“MB-450” manufactured by Tosei Container Co., Ltd.) 1 to obtain a mixed solution L1. At this time, the blending amount of the fluorescent agent with respect to the total mass of the liquid mixture L1 (hereinafter referred to as “fluorescent agent concentration”) is 0.0241% by mass. The liquid mixture L1 thus obtained was stirred at 1500 rpm for 5 minutes by the stirring means 3 (“Homodisper 2.5” manufactured by Primics), and the liquid mixture L1 was irradiated with ultraviolet light (66 W) to obtain the liquid mixture L1. When the degree of luminescence was visually observed, the luminescence of the mixed liquid L1 was clearly confirmed. Moreover, the point which changed the mixing amount of the specific component with 0 mass part, 0.5 mass part, 1.0 mass part, 10.0 mass parts (each fluorescent agent density | concentration is 0 mass%, 0.00247 mass% , 0.00493 mass% and 0.0471 mass%), the mixed liquids prepared by the same method as the above mixed liquid L1 were designated as L2, L3, L4, and L5, respectively. Similarly, these mixed liquids L2 to L5 were irradiated with ultraviolet light and the degree of light emission was visually observed. Although light emission could not be confirmed for the liquid mixture L2, the light emission intensity of the liquid mixtures L3 and L4 was lower than that of the liquid mixture L1, but the light intensity of the liquid mixture L5 was as high as that of the liquid mixture L1. The emission of was clearly confirmed. From these results, it was found that the presence or absence of mixing of the specific component A can be detected based on the fluorescence of the mixed solution, that is, based on the presence or absence of light emission of the mixed solution. Furthermore, it was found that the difference in the mixing amount of the specific component A can be detected based on the intensity of fluorescence of the mixed solution, that is, based on the light emission degree of the mixed solution. In this case, if the relationship between the mixing amount of the specific component A and the emission intensity is obtained in advance, it can be detected that the mixing amount is different from the specified amount.

尚、本発明は上記実施形態に限定されるものではない。例えば、上記実施形態では、混合液の例として粘着剤を挙げて説明したが、これに限定されず、易接着剤、剥離剤、ハードコート剤、インク受理剤等の機能性剤や、金属微粒子インクのように微粒子を分散剤に分散させてなる分散液を挙げることができる。   The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the pressure-sensitive adhesive has been described as an example of the mixed liquid. However, the present invention is not limited to this. Examples thereof include a dispersion liquid in which fine particles are dispersed in a dispersant, such as ink.

また、上記実施形態では、混合液Lの発光度合を目視にて確認する場合を例に説明したが、図2に示す混合状態確認システムMS2のように、混合液Lの蛍光を検出する検出手段5と、検出手段5により検出した蛍光を基に特定成分Aの混合ミスを解析する解析手段6とを更に備えてもよい。この場合、検出手段5としてはCCDカメラやCMOSカメラ等の公知の撮像部(撮像器)を用いることができると共に、解析手段6としては、演算処理を行うことができる公知のパーソナルコンピュータ等を用いることができる。そして、撮像部5により混合液Lの蛍光を検出して撮像し、撮像された画像が解析手段6に送られ、解析手段6により画像に公知の演算処理を施してコントラストの差を生じさせ、その演算処理結果に基づき混合ミスを解析する。これによれば、大型の容器1で多量の混合液Lを調製する場合であっても、容易に混合ミスを検出することができる。   Moreover, although the said embodiment demonstrated to the case where the light emission degree of the liquid mixture L was confirmed visually, the detection means which detects the fluorescence of the liquid mixture L like the mixed state confirmation system MS2 shown in FIG. 5 and an analysis means 6 for analyzing a mixing error of the specific component A based on the fluorescence detected by the detection means 5. In this case, a known imaging unit (imaging device) such as a CCD camera or a CMOS camera can be used as the detection unit 5, and a known personal computer or the like that can perform arithmetic processing is used as the analysis unit 6. be able to. Then, the fluorescence of the liquid mixture L is detected and imaged by the imaging unit 5, and the captured image is sent to the analysis unit 6. The analysis unit 6 performs known arithmetic processing on the image to cause a contrast difference, The mixing error is analyzed based on the calculation processing result. According to this, even when a large amount of the mixed liquid L is prepared in the large container 1, a mixing error can be easily detected.

また、図2に示すように、容器1内に複数種の成分(本実施形態では3種の成分A,B,C)を用途に応じて予め設定された量で夫々供給する供給管21,22,23を備える構成としてもよい。供給管21の途中には蛍光剤供給管24が接続されており、成分Aに蛍光剤を含有させることができるようになっている。ここで、成分Aと蛍光剤とが混合(溶解)し難い場合には、供給管21と蛍光剤供給管24との合流点の下流側で成分Aと蛍光剤とが十分に混合できず、その結果として、混合ミスを検出できなくなる虞がある。このように成分Aと蛍光剤とが混合し難い場合には、蛍光剤を含有させた成分Aを供給管21により供給することが好ましい。この場合、蛍光剤供給管24を省略できるため、装置構成を簡単にできる。   In addition, as shown in FIG. 2, a supply pipe 21 that supplies a plurality of types of components (three types of components A, B, and C in the present embodiment) to the container 1 in amounts set in advance according to the application, It is good also as a structure provided with 22 and 23. FIG. A fluorescent agent supply tube 24 is connected in the middle of the supply tube 21 so that the component A can contain the fluorescent agent. Here, when the component A and the fluorescent agent are difficult to mix (dissolve), the component A and the fluorescent agent cannot be sufficiently mixed on the downstream side of the confluence of the supply pipe 21 and the fluorescent agent supply pipe 24, As a result, there is a possibility that a mixing error cannot be detected. Thus, when component A and a fluorescent agent are difficult to mix, it is preferable to supply the component A containing a fluorescent agent through the supply pipe 21. In this case, since the fluorescent agent supply pipe 24 can be omitted, the apparatus configuration can be simplified.

また、上記実施形態では、混合液に紫外光を照射した側から検出した蛍光に基づき混合ミスを検出する場合について説明したが、透明な容器1を用いて、この容器1の側面側から検出した蛍光や、容器1の紫外光を照射した側とは反対側(底面側)から検出した蛍光に基づき混合ミスを検出するように構成してもよい。この場合、透光性を有する材料(例えば、ガラス)で作製された容器1を用い、容器1の側壁外側または光照射手段4と反対側に検出手段5を配置すればよい。   Moreover, although the said embodiment demonstrated the case where a mixing error was detected based on the fluorescence detected from the side which irradiated the ultraviolet light to the liquid mixture, it detected from the side surface side of this container 1 using the transparent container 1. You may comprise so that a mixing mistake may be detected based on fluorescence and the fluorescence detected from the side (bottom surface side) opposite to the side irradiated with the ultraviolet light of the container 1. In this case, the detection means 5 may be arranged on the outside of the side wall of the container 1 or on the side opposite to the light irradiation means 4 using the container 1 made of a light-transmitting material (for example, glass).

また、上記実施形態では、混合液に紫外光を照射しているが、混合液を基材(例えばウエブ)に塗布して形成した塗膜の表面に紫外光を照射することによっても、同様に混合ミスを検出することができる。しかしながら、ウエブに混合液を塗布した後に混合ミスが発覚すると、塗膜を形成したウエブが無駄になってしまう。このため、製造過程において上流の工程である混合液調製時に混合液の状態で混合ミスを検出することが好ましい。また、特定成分の有無のみを検出する場合には、攪拌前に紫外光を照射してもよい。   Moreover, in the said embodiment, although ultraviolet light is irradiated to a liquid mixture, also by irradiating the ultraviolet-ray to the surface of the coating film formed by apply | coating a liquid mixture to a base material (for example, web), it is the same. Mixing errors can be detected. However, if a mixing error is detected after the liquid mixture is applied to the web, the web on which the coating film is formed is wasted. For this reason, it is preferable to detect a mixing error in the state of the mixed solution when preparing the mixed solution, which is an upstream step in the manufacturing process. Moreover, when detecting only the presence or absence of a specific component, ultraviolet light may be irradiated before stirring.

また、上記実施形態では、ウエブに塗布する塗工液に蛍光剤を含有させる場合について説明したが、プラスチックフィルム製膜の溶融樹脂中あるいは製紙の紙料中に蛍光剤を含有させる場合にも本発明を適用することができる。この場合、フィルム等(プラスチックフィルムや紙)を搬送させながら、フィルム等に紫外光を照射し、そのフィルム等の発光度合に基づいてフィルム等に混合する特定成分の混合ミスを検出することができる。尚、溶融樹脂中あるいは紙料中の蛍光剤の濃度は、上記混合液中の蛍光剤の濃度と同様に設定することができる。   In the above-described embodiment, the case where the fluorescent agent is contained in the coating liquid to be applied to the web has been described. However, the present invention is also applicable to the case where the fluorescent agent is contained in the molten resin of the plastic film film or the paper stock. The invention can be applied. In this case, while conveying a film or the like (plastic film or paper), the film or the like is irradiated with ultraviolet light, and a mixing error of a specific component mixed with the film or the like can be detected based on the light emission degree of the film or the like. . In addition, the density | concentration of the fluorescent agent in molten resin or paper stock can be set similarly to the density | concentration of the fluorescent agent in the said liquid mixture.
