Description

本発明は、少なくとも筐体の一部がプラスチック材料からなる携帯電話機等の小型機器をはじめとする各種機器を、加熱した後に手分解する物品の解体方法に関するものである。   The present invention relates to a method for disassembling an article in which various devices including a small device such as a mobile phone, at least a part of which is made of a plastic material, are manually disassembled after being heated.

携帯電話やデジタルカメラ等の小型電子機器には、金などの貴金属をはじめ、インジウムなどのレアメタルが含まれるため、資源枯渇による影響が予測される我が国では、国内でのリサイクルが推進されている。一方、プラスチック材料は、軽量で、加工が容易であり、耐久性に優れるため、様々な筺体に用いられているが、比較的安価であるため、プラスチック材料を焼却して熱回収を行い、有価で取引きされる金属資源だけが回収されることが多かった。   Since small electronic devices such as mobile phones and digital cameras contain precious metals such as gold and rare metals such as indium, recycling in Japan is being promoted in Japan, where the impact of resource depletion is expected. On the other hand, plastic materials are lightweight, easy to process, and excellent in durability, so they are used in various housings. However, because they are relatively inexpensive, plastic materials are incinerated for heat recovery and valuable. Often, only the metal resources traded in were collected.

しかしながら、石油資源の枯渇が危惧される現在、プラスチック材料もできるだけ材料としてリサイクルされることが環境の観点から望まれている（非特許文献１）。また廃棄された物品を粉砕処理した場合、プラスチック、金属等の材料が混合され、リサイクルのための分別が必要となるため、分離のためのエネルギーが必要であった。さらに部品のリユースも一部、始まっているが、該当部品を損なわずに取り出す方法として、手解体が最適であるが、経済的に見合わないことからあまり推進されていなかった。   However, at present, when there is concern about the depletion of petroleum resources, it is desired from the environmental point of view that plastic materials be recycled as much as possible (Non-Patent Document 1). In addition, when a discarded article is pulverized, materials such as plastic and metal are mixed and need to be separated for recycling. Therefore, energy for separation is required. In addition, some parts have been reused, but manual disassembly is the best way to remove the parts without damaging them, but it has not been promoted much because it is not economically appropriate.

以上のように小型電子機器等のリサイクルにおいて、手解体の必要性が高まってきている。しかしながら、携帯電話機に代表されるように情報通信に関わる電子機器類の技術革新が早く、モデルチェンジが迅速に行われるため、１台ごとに解体手順や接合箇所・接合方法が異なり、その探索に時間を要する。さらに部品の締結に用いられるねじの形状は、一種類ではなく、例えば携帯電話機では、ねじ頭部の形状が＋（プラス）、−（マイナス）といったものだけではなく、Ｙ字、星型、車輪型 等、様々であり、１台の物品を手解体するために、一種類の道具では完了しないことが多く、道具を用意する手間もかかっていた。   As described above, there is an increasing need for manual disassembly in recycling of small electronic devices and the like. However, since the technological innovation of electronic devices related to information communication, such as mobile phones, is fast and model changes are made quickly, the disassembly procedure, joining location and joining method differ for each unit. It takes time. Furthermore, the shape of the screw used for fastening the components is not one type. For example, in a mobile phone, the shape of the screw head is not only + (plus),-(minus), but also Y-shaped, star-shaped, wheels There were various types, and in order to dismantle one article by hand, it was often not completed with one kind of tool, and it took time and effort to prepare the tool.

そこで、リサイクルの現場では、よりコストが安い機械破砕や焼却により物品を破壊し、一部の金属材料（金、銅、銀 等）が回収されているのが実情であり、部品の再利用を含む、より高品質なリサイクルを達成するためには、手解体時間を短縮して、コストを削減することが課題であった。   Therefore, at the recycling site, the actual situation is that some of the metal materials (gold, copper, silver, etc.) are recovered by mechanical crushing and incineration, which are less expensive, and the parts are reused. In order to achieve higher quality recycling, including the problem, it was a problem to reduce the manual disassembly time and reduce the cost.

物品の手解体を容易にする方法として、所定温度以上に加熱するとねじによる締結が無効となる易分解締結部によって組み立てられた物品に、過熱蒸気を供給して物品を分解する方法が提案されている（特許文献１参照）。   As a method for facilitating manual disassembly of an article, there has been proposed a method for disassembling an article by supplying superheated steam to an article assembled by an easily disassembling fastening portion that is not fastened with screws when heated to a predetermined temperature or higher. (See Patent Document 1).

しかしながら、特許文献１に開示された分解方法では、易分解締結を可能とするねじを使用する必要があり、そのようなねじが一般に広まっていない現状では、実用的ではないという問題点があった。   However, in the disassembling method disclosed in Patent Document 1, it is necessary to use a screw that allows easy disassembly and fastening, and there is a problem that such a screw is not practical in the current situation where such a screw is not widely spread. .

本発明は、上記課題を解決するためになされたもので、プラスチック筺体からなる物品の解体方法において、材料リサイクルおよび部品の再利用を可能とし、かつ後工程の手解体時間を短縮し、解体に要するコストを低減することが可能な解体方法を提供することを目的とする。   The present invention has been made to solve the above problems, and in a method of disassembling an article made of a plastic casing, enables material recycling and reuse of parts, and shortens the manual disassembly time of the post-process, thereby disassembling. It aims at providing the dismantling method which can reduce the cost which requires.

［第１の実施の形態］
以下、本発明の実施の形態について図面を参照して説明する。図１は本実施の形態に係る物品の解体方法を説明するフローチャート、図２は本実施の形態に係る処理装置の構成を示すブロック図である。
本実施の形態では、少なくとも筐体の一部がプラスチック材料からなる携帯電話機等の物品１を処理装置２に投入し（ステップＳ１００）、処理装置２の内部に設けられた過熱水蒸気発生装置３によって常圧で１００℃以上に加熱した過熱水蒸気に物品１を曝して、プラスチック材料を加熱することにより、プラスチック材料を軟化させる（ステップＳ１０１）。 [First Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart for explaining an article disassembling method according to the present embodiment, and FIG. 2 is a block diagram showing a configuration of a processing apparatus according to the present embodiment.
In the present embodiment, an article 1 such as a mobile phone in which at least a part of the casing is made of a plastic material is put into the processing apparatus 2 (step S100), and the superheated steam generator 3 provided inside the processing apparatus 2 is used. The plastic material is softened by exposing the article 1 to superheated steam heated to 100 ° C. or higher at normal pressure to heat the plastic material (step S101).

過熱水蒸気は、食品加工等の分野で既に実用化されており、過熱水蒸気発生装置も一般に使用されるようになっている。例えば、＜ｈｔｔｐ：／／ｗｗｗ．ｓｈｉｎｎｅｔｓｕ．ｃｏ．ｊｐ／ｐｒｏｄｕｃｔｓ／１９／ｉｎｄｅｘ．ｈｔｍｌ＞に開示されているように、過熱水蒸気による加熱とオーブンなどによる加熱との違いは、水蒸気が介在することにより、熱伝達効率が高く、また短時間で温度一定となるため、短時間での処理が可能なことである。   Superheated steam has already been put into practical use in the field of food processing and the like, and a superheated steam generator is generally used. For example, <http: // www. shinnetsu. co. jp / products / 19 / index. As disclosed in html>, the difference between heating with superheated steam and heating with an oven is that the heat transfer efficiency is high due to the presence of steam, and the temperature is constant in a short time. Is possible.

次に、加熱した物品１を作業者が手で解体し（ステップＳ１０２）、作業者が部品毎あるいは材料毎に分別し（ステップＳ１０３）、分別した部品や材料を再資源化業者に渡す（ステップＳ１０４）。再資源化業者は、回収した部品や材料の再資源化（中古部品としての再利用や、再生プラスチックの生成、金属の精錬、貴金属の回収など）を行う。   Next, the heated article 1 is dismantled by hand (step S102), and the worker separates the parts or materials by parts (step S103), and delivers the sorted parts and materials to the recycling company (step S103). S104). The recycling company recycles the collected parts and materials (reuse as used parts, generation of recycled plastic, metal refining, recovery of precious metals, etc.).

本実施の形態では、以上のような解体方法の１例として、携帯電話機の解体を行った。具体的には、アクリロニトリル・ブタジエン・スチレン樹脂（ＡＢＳ）を筐体素材とする携帯電話機をバッチ式処理装置に３分間設置して過熱水蒸気処理した後、手で解体を行い、液晶ディスプレイ、基板、カメラおよびモーターと筐体とに分離した。ＡＢＳの軟化温度は概ね１００℃付近である。過熱水蒸気雰囲気下の温度を測定したところ、雰囲気の温度は１７０℃であったのにも関わらず、筺体表面は１３０℃未満、液晶表面は８０℃未満であった。携帯電話機の解体に要した平均時間は２分であり、ねじ回しなどは不要であった。   In the present embodiment, the mobile phone is disassembled as an example of the disassembly method as described above. Specifically, a mobile phone using acrylonitrile, butadiene, styrene resin (ABS) as a casing material is placed in a batch processing apparatus for 3 minutes and subjected to superheated steam treatment, then dismantled by hand, and a liquid crystal display, a substrate, Separated into camera and motor and housing. The softening temperature of ABS is approximately around 100 ° C. When the temperature in the superheated steam atmosphere was measured, the surface of the enclosure was less than 130 ° C. and the surface of the liquid crystal was less than 80 ° C. despite the fact that the temperature of the atmosphere was 170 ° C. The average time required for dismantling the mobile phone was 2 minutes, and no screwdriver was required.

通常、ねじ回しなどの道具を用いて携帯電話機を解体した場合、平均で１２分かかることから、本実施の形態によれば解体時間を大幅に短縮できることが分かる。また、ＡＢＳからなる筐体部分は軟化温度以上の温度に上昇したが、液晶ディスプレイや内部の表面の最大温度は動作保障温度内であった。このため、部品の機能を損なうことはなく、解体分離した液晶ディスプレイ、カメラおよひモーターは動作し、再利用できることを確認した。   Normally, when a mobile phone is disassembled using a tool such as a screwdriver, it takes 12 minutes on average, and it can be seen that the disassembly time can be greatly reduced according to this embodiment. Further, the casing portion made of ABS rose to a temperature equal to or higher than the softening temperature, but the maximum temperature of the liquid crystal display and the internal surface was within the guaranteed operating temperature. For this reason, it was confirmed that the liquid crystal display, camera, and motor that were disassembled worked and could be reused without impairing the function of the parts.

なお、本実施の形態では、部品を再利用できるようにすることから、部品の信頼性を確保することができ部品を再利用することが可能な程度の過熱水蒸気の温度および曝露時間であることが望ましい。
過熱水蒸気の温度は、過熱水蒸気でプラスチック材料が、その軟化温度よりも５〜３０℃以上の温度になるように設定すればよい。また、過熱水蒸気に物品を曝す曝露時間は、３０秒から１０分の短時間の範囲で設定すればよい。 In this embodiment, since the component can be reused, the temperature of the superheated steam and the exposure time must be such that the reliability of the component can be ensured and the component can be reused. Is desirable.
What is necessary is just to set the temperature of superheated steam so that a plastic material may be 5-30 degreeC or more rather than the softening temperature with superheated steam. Moreover, what is necessary is just to set the exposure time which exposes articles | goods to superheated steam in the range for a short time of 30 seconds to 10 minutes.

次に、本発明の第２の実施の形態について説明する。本実施の形態では、ポリアミド（ＰＡ）とガラスファイバーとの複合体を筐体素材とする携帯電話機を第１の実施の形態と同じ条件のバッチ式処理装置に３分間設置して過熱水蒸気処理した後、作業者が手で携帯電話機の解体を行い、液晶ディスプレイ、基板、カメラおよびモーターと筐体とに分離した。携帯電話機の解体に要した平均時間は２分であり、ねじ回しなどは不要であった。また、分離した液晶ディスプレイ、カメラおよびモーターは動作し、再利用できることを確認した。 [Second Embodiment]
Next, a second embodiment of the present invention will be described. In this embodiment, a cellular phone using a composite material of polyamide (PA) and glass fiber as a casing material is placed in a batch processing apparatus under the same conditions as in the first embodiment for 3 minutes and subjected to superheated steam treatment. Later, the operator manually disassembled the mobile phone and separated it into a liquid crystal display, a substrate, a camera, a motor, and a housing.
