本発明は、透明の結晶化ガラスを含むカレットの中から透明の結晶化ガラスを分別するカレット分別装置およびカレット分別方法に関する。 The present invention relates to a cullet sorting apparatus and a cullet sorting method for separating transparent crystallized glass from cullet containing transparent crystallized glass.

従来から、ガラス製造工場等においては、ガラス材料としてカレット（リサイクル用ガラス片）を利用しているが、カレットには、有色または透明、非結晶化ガラスまたは結晶化ガラス等の様々な種類のガラスが含まれることから、これらカレットの分別を行う必要がある。 Conventionally, cullet (glass pieces for recycling) has been used as a glass material in glass manufacturing factories, etc., but cullet is a variety of types of glass such as colored or transparent, non-crystallized glass or crystallized glass. It is necessary to separate these cullet because it contains.

このようなカレット分別装置の一例としては、薄茶色或いは紫色の結晶化ガラス（耐熱ガラス）と多色の非結晶化ガラス（ソーダガラス）とを含むカレット中から、薄茶色或いは紫色の結晶化ガラスを分別するカレット分別装置であって、４３０ｎｍ以下の波長を有する光によって、無色透明および薄青色の非結晶化ガラスと、それ以外のガラスとを分別し、６３０ｎｍ〜７００ｎｍの波長を有する光によって、薄茶色或いは紫色の結晶化ガラスとそれ以外の色のガラスとを分別するカレット分別装置が知られている（例えば、特許文献１を参照）。 As an example of such a cullet sorting device, a light brown or purple crystallized glass from a cullet containing light brown or purple crystallized glass (heat resistant glass) and multicolored non-crystallized glass (soda glass). A cullet separator that separates colorless transparent and light blue non-crystallized glass with light having a wavelength of 430 nm or less and other glass, and by light having a wavelength of 630 nm to 700 nm. A cullet sorting device that separates light brown or purple crystallized glass and glass of other colors is known (see, for example, Patent Document 1).

この特許文献１のカレット分別装置では、薄茶色或いは紫色の結晶化ガラスを分別して排除することにより、通常のびん等を構成する非結晶化ガラスに、結晶化ガラスが混入することを回避している。 In the cullet sorting apparatus of Patent Document 1, by separating and eliminating the light brown or purple crystallized glass, it is possible to prevent the crystallized glass from being mixed with the non-crystallized glass constituting a normal bottle or the like. There is.

特許第３３６７９３５号公報Japanese Patent No. 3376935

ところが、近年、透明色のガラスを利用して成形されたリサイクル製品において、リサイクル製品への内容物の充填時やリサイクル製品の搬送時に、リサイクル製品が破損する事例が若干ではあるものの発生している。 However, in recent years, in recycled products molded using transparent glass, there have been some cases where the recycled products are damaged when the contents are filled in the recycled products or when the recycled products are transported. ..

そこで、本出願人が原因を調査したところ、リサイクル用に回収されたカレット内に、以前は含まれていなかった透明の結晶化ガラスが含まれており、このような透明の結晶化ガラスは、透明の非結晶化ガラスと膨張率が異なるため、リサイクル製品に破損が生じ易くなっていることを突き止めた。リサイクル用に回収されるカレットの中に透明の結晶化ガラスが含まれるようになってきたのは、近年、耐熱性を備えた透明色のガラスから形成された鍋等の調理器具や食器等が普及してきており、これら製品がリサイクル用に回収されるようになってきたためだと推測される。 Therefore, when the applicant investigated the cause, the cullet recovered for recycling contained transparent crystallized glass that was not previously contained, and such transparent crystallized glass was found. We found that recycled products are prone to damage due to their different expansion rates from clear non-glassed glass. In recent years, transparent crystallized glass has come to be included in the cullet collected for recycling in cooking utensils such as pots and tableware made of heat-resistant transparent glass. It is presumed that this is because these products have become widespread and are being collected for recycling.

そして、この場合、特許文献１に記載のカレット分別装置では、４３０ｎｍ以下の波長を有する光を照射した時に、透明の非結晶化ガラスおよび透明の結晶化ガラスの両方が、透明のガラスとして判別されてしまうため、透明の結晶化ガラスがリサイクル用のガラスとして取り扱われてしまう。 In this case, in the cullet sorting apparatus described in Patent Document 1, both the transparent non-crystallized glass and the transparent crystallized glass are discriminated as transparent glass when irradiated with light having a wavelength of 430 nm or less. Therefore, the transparent crystallized glass is treated as glass for recycling.

そこで、本発明の目的は、簡素かつ安価な構成で、透明の結晶化ガラスを分別することが可能なカレット分別装置およびカレット分別方法を提供することである。 Therefore, an object of the present invention is to provide a cullet sorting apparatus and a cullet sorting method capable of sorting transparent crystallized glass with a simple and inexpensive configuration.

本発明のカレット分別装置は、カレットを分別するカレット分別装置であって、ピーク波長３３０ｎｍ以上の紫外線をカレットに対して照射した場合の紫外線透過量により透明の結晶化ガラスを分別することにより、前記課題を解決するものである。

It solves the problem.

以下に、本発明の一実施形態に係るカレット分別装置１０について、図面に基づいて説明する。 Hereinafter, the cullet sorting apparatus 10 according to the embodiment of the present invention will be described with reference to the drawings.

まず、カレット分別装置１０は、有色（黒色）の非結晶化ガラス、有色（茶色）の結晶化ガラス、透明の非結晶化ガラス、および、透明の結晶化ガラスを含むカレットＷの中から、透明の結晶化ガラスを分別するものである。 First, the cullet sorting device 10 is transparent from among cullet W containing colored (black) non-crystallized glass, colored (brown) crystallized glass, transparent non-crystallized glass, and transparent crystallized glass. It separates the crystallized glass of.

なお、一般的には、有色の非結晶化ガラスや透明の非結晶化ガラスは、リサイクル用途で使用され、有色の結晶化ガラスや透明の結晶化ガラスは、廃棄されることになる。 In general, colored non-crystallized glass and transparent non-crystallized glass are used for recycling, and colored crystallized glass and transparent crystallized glass are discarded.

カレット分別装置１０は、図１に示すように、振動フィーダ等から成るカレット供給部２０と、カレット通過経路を挟んで配置される紫外線光源３０および紫外線センサー４０と、カレット通過経路を挟んで配置されるＬＥＤ等から成る可視光源５０およびカラーカメラ等から成る可視光センサー６０と、エアーを噴出して特定のカレットＷを吹き飛ばすエアーノズル７０と、リサイクル用途のカレットＷを収容する回収ボックス８０と、排除するカレットＷを収容する排除ボックス９０と、紫外線センサー４０や可視光センサー６０やエアーノズル７０等の各部を制御する制御部（図示しない）とを備えている。 As shown in FIG. 1, the cullet sorting device 10 is arranged with a cullet supply unit 20 composed of a vibration feeder or the like, an ultraviolet light source 30 and an ultraviolet sensor 40 arranged across the cullet passage path, and the cullet passage path. A visible light source 50 composed of an LED or the like, a visible light sensor 60 composed of a color camera or the like, an air nozzle 70 that ejects air to blow off a specific cullet W, and a collection box 80 that houses the cullet W for recycling are eliminated. It is provided with an exclusion box 90 for accommodating the cullet W to be used, and a control unit (not shown) for controlling each part such as the ultraviolet sensor 40, the visible light sensor 60, and the air nozzle 70.

本実施形態では、紫外線光源３０が紫外線ＬＥＤとして構成され、紫外線センサー４０が、シリコンＵＶセンサー（シリコンフォトダイオードを有した紫外線量を測定可能なセンサー）として構成されている。 In the present embodiment, the ultraviolet light source 30 is configured as an ultraviolet LED, and the ultraviolet sensor 40 is configured as a silicon UV sensor (a sensor having a silicon photodiode that can measure the amount of ultraviolet rays).

次に、カレット分別装置１０を用いた透明の結晶化ガラスのカレット分別方法について、以下に説明する。 Next, a method for separating cullet of transparent crystallized glass using the cullet sorting device 10 will be described below.

まず、本実施形態のカレット分別方法は、各種カレットＷに対して紫外線を照射した時の紫外線透過量（紫外線透過率）の違いを利用して、透明の結晶化ガラスとそれ以外のガラスとを分別するものである。 First, in the cullet sorting method of the present embodiment, transparent crystallized glass and other glass are separated by utilizing the difference in the amount of ultraviolet rays transmitted (ultraviolet transmittance) when various cullet Ws are irradiated with ultraviolet rays. It is for sorting.

具体的に説明すると、図２のグラフに示すように、ピーク波長３３０〜３８０ｎｍの紫外線を各種カレットＷに対して照射した場合、透明の非結晶化ガラスでは、ピーク波長３３０ｎｍの紫外線では約２０〜５５％程度の透過率を計測し、ピーク波長３８０ｎｍの紫外線では約８０〜９０％程度の透過率を計測する。
これに対して、透明の結晶化ガラスでは、ピーク波長３３０ｎｍの紫外線では約０％の透過率を計測し、ピーク波長３８０ｎｍの紫外線では約４０〜６０％程度の透過率を計測し、また、有色の非結晶化ガラスおよび有色の結晶化ガラスでは、ピーク波長３３０〜３８０ｎｍの紫外線で、約０％の透過率となる。 Specifically, as shown in the graph of FIG. 2, when various cullet Ws are irradiated with ultraviolet rays having a peak wavelength of 330 to 380 nm, the transparent non-crystallized glass has about 20 to 20 to ultraviolet rays having a peak wavelength of 330 nm. A transmittance of about 55% is measured, and a transmittance of about 80 to 90% is measured for ultraviolet rays having a peak wavelength of 380 nm.
On the other hand, in transparent crystallized glass, the transmittance is measured at about 0% for ultraviolet rays having a peak wavelength of 330 nm, and about 40 to 60% is measured for ultraviolet rays having a peak wavelength of 380 nm, and the color is colored. In the non-crystallized glass and the colored crystallized glass, the transmission rate is about 0% at the peak wavelength of 330 to 380 nm.

このように、対象となるガラスの厚みに関わらず、ピーク波長３３０〜３８０ｎｍの紫外線を照射することにより、少なくとも透明の非結晶化ガラスと透明の結晶化ガラスとを良好に判別することができる。なお、図２に示す３、５、６、８ｍｍとは、カレットＷの厚みのことを意味している。 In this way, at least transparent non-crystallized glass and transparent crystallized glass can be satisfactorily discriminated by irradiating ultraviolet rays having a peak wavelength of 330 to 380 nm regardless of the thickness of the target glass. In addition, 3, 5, 6, 8 mm shown in FIG. 2 means the thickness of the cullet W.

また、ピーク波長約３３０〜３５０ｎｍの紫外線では、図２のグラフに示すように、透明の結晶化ガラスと有色の非結晶化ガラスと有色の結晶化ガラスとの間で、紫外線の透過率に殆ど差が見られないため、これらガラスを分別することは難しいが、特許文献１に記載されるように、これらガラスに可視光源５０によって可視光を照射し、可視光センサー６０によって可視光の透過率を測定することにより、これらガラスを分別することができる。なお、可視光を利用した分別の工程については、紫外線を利用した分別の工程の前後に任意に実施すればよい。 Further, in the case of ultraviolet rays having a peak wavelength of about 330 to 350 nm, as shown in the graph of FIG. 2, the transmittance of ultraviolet rays is almost the same between the transparent crystallized glass, the colored non-crystallized glass and the colored crystallized glass. It is difficult to separate these glasses because there is no difference, but as described in Patent Document 1, these glasses are irradiated with visible light by the visible light source 50, and the visible light transmission rate is increased by the visible light sensor 60. These glasses can be separated by measuring. The sorting step using visible light may be arbitrarily performed before and after the sorting step using ultraviolet rays.

次に、紫外線透過量の違いを利用して、透明の非結晶化ガラスと透明の結晶化ガラスとを判別可能であるかを確認するために行った実験について、図３および図４に基いて説明する。 Next, based on FIGS. 3 and 4, the experiment conducted to confirm whether the transparent non-crystallized glass and the transparent crystallized glass can be distinguished by using the difference in the amount of ultraviolet light transmitted. explain.

まず、本実験の条件については、以下の通りである。
紫外線光源３０：ナイトライドセミコンダクタ社製の紫外線ＬＥＤ、品番：ＮＳ３６５Ｌ−５ＣＦＡ（ピーク波長：３６５ｎｍ）
紫外線センサー４０：京セミ社製のシリコンＵＶセンサー、品番：ＫＰＤＵ４００Ｗ−２
ガラス：３×３０×６０ｍｍの、透明の非結晶化ガラスおよび透明の結晶化ガラス
紫外線光源３０と紫外線センサー４０との間隔：約８ｍｍ First, the conditions of this experiment are as follows.
Ultraviolet light source 30: Ultraviolet LED manufactured by Nitride Semiconductor, product number: NS365L-5CFA (peak wavelength: 365 nm)
Ultraviolet sensor 40: Silicon UV sensor manufactured by Kyosemi, product number: KDDU400W-2
Glass: 3 x 30 x 60 mm, transparent non-crystallized glass and transparent crystallized glass Distance between the UV light source 30 and the UV sensor 40: Approximately 8 mm

上記の実験では、図４のグラフに示すように、紫外線センサー４０の計測値（紫外線透過量）が１．３５Ｖであるところ、透明の結晶化ガラスの通過時には、紫外線センサー４０の計測値（紫外線透過量）が約０．７５Ｖに減少し、また、透明の非結晶化ガラスの通過時には、紫外線センサー４０の計測値（紫外線透過量）が約１．４６Ｖに増加した。
このことから、紫外線透過量によって、透明の非結晶化ガラスと透明の結晶化ガラスとが判別可能であることが分かった。 In the above experiment, as shown in the graph of FIG. 4, the measured value (ultraviolet ray transmission amount) of the ultraviolet sensor 40 is 1.35 V, but when passing through the transparent crystallized glass, the measured value (ultraviolet ray) of the ultraviolet sensor 40 (Transmission amount) decreased to about 0.75V, and the measured value (ultraviolet transmission amount) of the ultraviolet sensor 40 increased to about 1.46V when passing through the transparent non-crystallized glass.
From this, it was found that the transparent non-crystallized glass and the transparent crystallized glass can be distinguished from each other by the amount of ultraviolet light transmitted.

また、紫外線光源３０としての紫外線ＬＥＤに、２０ｍＡの電流が流れた時に、紫外線ＬＥＤの出力が１．２〜１．８ｍＷであり、紫外線ＬＥＤに１ｍＡの電流が流れた時に、紫外線センサー４０によって、透明の非結晶化ガラスと透明の結晶化ガラスとが分別可能であった。このことから、図５のグラフを基に、分別に必要とされる紫外線光源３０の出力は、０．０６ｍＷ以上であることが推測される。 Further, when a current of 20 mA flows through the ultraviolet LED as the ultraviolet light source 30, the output of the ultraviolet LED is 1.2 to 1.8 mW, and when a current of 1 mA flows through the ultraviolet LED, the ultraviolet sensor 40 causes the output of the ultraviolet LED to be 1.2 to 1.8 mW. It was possible to separate transparent non-crystallized glass and transparent crystallized glass. From this, it is estimated that the output of the ultraviolet light source 30 required for sorting is 0.06 mW or more based on the graph of FIG.

このようにして得られた本実施形態では、透明の結晶化ガラスを含む各種カレットＷに対して紫外線を照射した時の紫外線透過量の違いを利用して、簡素かつ安価な構成で、透明の結晶化ガラスを分別することができる。
また、特許文献１に記載されるような、可視光の透過率の測定によってガラスを分別する装置との間で、カレット供給部２０やエアーノズル７０等の設備について共通化することができる。これにより、紫外線の透過率を利用して透明の結晶化ガラスを分別する機能を付加する場合に、追加で必要とされる設備が、紫外線光源３０および紫外線センサー４０で済むため、装置コストを低廉に抑えることができる。 In the present embodiment thus obtained, various cullet Ws containing transparent crystallized glass are transparent with a simple and inexpensive configuration by utilizing the difference in the amount of ultraviolet rays transmitted when the cullet W is irradiated with ultraviolet rays. Crystallized glass can be separated.
Further, equipment such as a cullet supply unit 20 and an air nozzle 70 can be shared with an apparatus for separating glass by measuring the transmittance of visible light as described in Patent Document 1. As a result, when adding a function of separating transparent crystallized glass using the transmittance of ultraviolet rays, the additional equipment required is an ultraviolet light source 30 and an ultraviolet sensor 40, so that the equipment cost is low. Can be suppressed to.

以上、本発明の実施形態を詳述したが、本発明は上記実施形態に限定されるものではなく、特許請求の範囲に記載された本発明を逸脱することなく種々の設計変更を行なうことが可能である。 Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the present invention described in the claims. It is possible.

例えば、上述した実施形態では、紫外線光源３０が紫外線ＬＥＤとして構成されているものとして説明したが、紫外線光源３０の具体的態様については、ピーク波長３３０ｎｍ〜３８０ｎｍの紫外線を照射可能なものであれば、ブラックライト等の如何なるものでもよい。
なお、紫外線光源３０は、近年、半値幅が狭い光源についても安価に供給されていることから、紫外線光源３０の半値幅は、±１５ｎｍ以内であることが望ましい。この場合、外乱要因によって判別結果が乱れることを回避することができる。 For example, in the above-described embodiment, the ultraviolet light source 30 has been described as being configured as an ultraviolet LED, but the specific embodiment of the ultraviolet light source 30 is such that it can irradiate ultraviolet rays having a peak wavelength of 330 nm to 380 nm. , Black light, etc. may be used.
Since the ultraviolet light source 30 has been inexpensively supplied in recent years even for a light source having a narrow half-value width, it is desirable that the half-value width of the ultraviolet light source 30 is within ± 15 nm. In this case, it is possible to prevent the discrimination result from being disturbed by a disturbance factor.

上述した実施形態では、紫外線センサー４０がシリコンＵＶセンサー（シリコンフォトダイオードを有した紫外線量を測定可能なセンサー）として構成されているものとして説明したが、紫外線センサー４０の具体的態様については、紫外線量を計測可能なものであれば、ＣＣＤカメラ等の如何なるものでもよい。 In the above-described embodiment, the ultraviolet sensor 40 has been described as being configured as a silicon UV sensor (a sensor having a silicon photodiode that can measure the amount of ultraviolet rays). However, a specific embodiment of the ultraviolet sensor 40 is an ultraviolet ray. Any one such as a CCD camera may be used as long as the amount can be measured.
