上記課題を鑑み、本発明は、電子・電気機器部品屑を適切且つ効率的に選別することが可能な電子・電気機器部品屑の処理方法を提供する。   In view of the above problems, the present invention provides a method for treating electronic / electrical device component waste that can appropriately and efficiently sort electronic / electrical device component waste.

本発明者らは、上記課題を解決するために鋭意検討したところ、電子・電気機器部品屑の中から所望の部品を効率良く選別するための手法として、種々の部品屑を含む電子・電気機器部品屑の中から基板を選択的に除去することが重要であることを見出した。そして、基板屑を除去するための良好な手法を種々検討したところ、特定の色彩選別機を用いることが有効であるとの知見を得た。   The present inventors have intensively studied to solve the above problems, and as a technique for efficiently selecting a desired part from electronic / electrical equipment part waste, electronic / electrical equipment containing various part wastes. It has been found that it is important to selectively remove the substrate from the component waste. And when various good methods for removing substrate waste were examined, it was found that it was effective to use a specific color sorter.

以上の知見を基礎として完成した本発明の実施の形態は一側面において、電子・電気機器部品屑の処理方法であって、処理対象物の表裏両面の色彩を識別可能な少なくとも2台のカメラユニットを備える色彩選別機を用いて、電子・電気機器部品屑中の基板屑を選別する工程を含む電子・電気機器部品屑の処理方法が提供される。   The embodiment of the present invention completed on the basis of the above knowledge is, in one aspect, a method for processing electronic / electric equipment component waste, and at least two camera units capable of distinguishing the colors of the front and back surfaces of the processing object. There is provided a method for processing electronic / electrical device component waste, including a step of selecting substrate waste in electronic / electrical device component waste using a color sorter.

本開示によれば、電子・電気機器部品屑を適切且つ効率的に選別することが可能な電子・電気機器部品屑の処理方法が提供できる。   According to the present disclosure, it is possible to provide an electronic / electric equipment component waste processing method that can appropriately and efficiently sort electronic / electric equipment component waste.

本発明の実施の形態に色彩選別機の構成を表す概略図である。It is the schematic showing the structure of the color sorter | selector in embodiment of this invention. エアノズルが備える穴の断面積及びピッチを説明する説明図である。It is explanatory drawing explaining the cross-sectional area and pitch of a hole with which an air nozzle is provided.

本発明の実施の形態に係る電子・電気機器部品屑の処理方法は、処理対象物の表裏両面の色彩を識別可能な少なくとも2台のカメラユニット3a、3bを備える色彩選別機1を用いて、電子・電気機器部品屑中の基板屑を選別する工程を含む。   The electronic / electrical equipment component waste processing method according to the embodiment of the present invention uses a color sorter 1 including at least two camera units 3a and 3b that can identify the colors of both front and back surfaces of a processing object. It includes a step of sorting substrate waste in electronic / electric equipment component waste.

本発明の実施の形態における「電子・電気機器部品屑」とは、廃家電製品・PCや携帯電話等の電子・電気機器を破砕した屑であり、回収された後、適当な大きさに破砕されたものを指す。本発明では、電子・電気機器部品屑とするための破砕は、処理者自身が行ってもよいが、市中で破砕されたものを購入等したものでもよい。   “Electronic / electrical device parts waste” in the embodiment of the present invention refers to wastes obtained by crushing waste electrical appliances / electronic / electrical devices such as PCs and mobile phones, and after being collected, they are crushed to an appropriate size. It points to what was done. In the present invention, crushing to make electronic / electric equipment component waste may be performed by the processor himself, or may be purchased from the city.

破砕方法として、特定の装置には限定されず、せん断方式でも衝撃方式でも構わないが、できる限り、部品の形状を損なわない破砕がのぞましい。したがって、細かく粉砕することを目的とする粉砕機のカテゴリーに属する装置は含まれない。   The crushing method is not limited to a specific device, and either a shearing method or an impact method may be used, but crushing that does not impair the shape of the part is preferable. Therefore, devices belonging to the category of grinders intended to be finely ground are not included.

以下に限定されるものではないが、本実施形態では、電子・電気機器部品屑は、最大直径100mm以下程度、更には50mm以下程度に破砕されているものが好ましい。さらに、本実施形態に係る電子・電気機器部品屑の原料を予め粗破砕することにより、コンデンサ、プラスチック、基板、線屑、IC、コネクタ、メタル等の形態で単体分離しておくことが好ましい。   Although not limited to the following, in this embodiment, it is preferable that the electronic / electrical device component waste is crushed to a maximum diameter of about 100 mm or less, and further about 50 mm or less. Furthermore, it is preferable to separate the raw materials for electronic / electric equipment component scraps according to this embodiment in advance in the form of capacitors, plastics, substrates, wire scraps, ICs, connectors, metals, and the like.

本実施形態に係る電子・電気機器部品屑は、基板、パーツ、筐体などに使われる合成樹脂類(プラスチック)、線屑、メタル、フィルム状部品屑、破砕や粉砕によって生じる粉状物、その他、からなる部品屑に分類することができ、処理目的に応じて更に細かく分類することができる。以下に限定されるものではないが、本実施形態では、部品屑として単体分離されている割合が70%以上の電子・電気機器部品屑を好適に処理することができる。   Electronic / electrical equipment component waste according to this embodiment is synthetic resin (plastic) used for substrates, parts, housings, wire waste, metal, film-like component waste, powdered material generated by crushing and crushing, and others , And can be further finely classified according to the processing purpose. Although not limited to the following, in this embodiment, it is possible to suitably process electronic / electric equipment component waste having a ratio of 70% or more as single component separation.

特に、本実施形態に係る色彩選別機の処理対象物としては、上述の電子・電気機器部品屑に対して風力選別を実施し、粉状物とフィルム状部品屑を除去した後の物質を処理することが好ましい。風力選別によって電子・電気機器部品屑中から粉状物とフィルム状部品屑等の軽量物を予め取り除いておくことにより、後述する色彩選別機内やメタルソータ内において粉状物とフィルム状部品屑等が舞い上がり、視界不良となることによって、色彩選別機又はメタルソータが備えるカメラユニットの検知能力の低下を抑制することができる。   In particular, as an object to be processed by the color sorter according to the present embodiment, the above-mentioned electronic / electric equipment component waste is subjected to wind sorting, and the substance after the powdery material and the film-like component waste are removed is processed. It is preferable to do. By removing in advance the light-weight materials such as powder and film-like component waste from the electronic / electric equipment component waste by wind sorting, the powder and film-like component waste etc. in the color sorter and metal sorter described later By soaring and having poor visibility, it is possible to suppress a decrease in the detection capability of the camera unit included in the color sorter or the metal sorter.

また、風力選別によって電子・電気機器部品屑中から粉状物とフィルム状部品屑等の軽量物を予め取り除いておくことにより、合成樹脂類、メタル、基板、IC、コンデンサなどの金属を含有する部品屑の含有比率を高くすることができる。   In addition, it contains metal such as synthetic resins, metals, substrates, ICs, capacitors, etc. by removing in advance the lightweight materials such as powder and film-like parts from the electronic and electrical equipment parts by wind sorting. The content ratio of component waste can be increased.

風力選別は少なくとも2段階で行われることが好ましい。まず、第1段階目の風力選別において、本実施形態に係る色彩選別機での選別能力に悪影響を与える可能性のある粉状物とフィルム状部品屑(樹脂、アルミ箔等)を除去することができる。第1段階目の風力選別工程は、例えば、風量を5〜20m/s、より好ましくは5〜12m/s、更には5〜10m/s程度、更には6〜8m/sで設定することができる。   The wind sorting is preferably performed in at least two stages. First, in the first-stage wind power sorting, removing powdery substances and film-like component waste (resin, aluminum foil, etc.) that may adversely affect the sorting ability of the color sorter according to this embodiment. Can do. In the first stage wind sorting process, for example, the air volume is set to 5 to 20 m / s, more preferably 5 to 12 m / s, further about 5 to 10 m / s, and further 6 to 8 m / s. it can.

2段階目の風力選別は、紛状物とフィルム状部品屑が除去された電子・電気機器部品屑から、合成樹脂類及び基板を濃縮することを目的とした選別が行われることが好ましい。例えば、2段階目の風力選別の風量を5〜20m/s、より好ましくは10〜18m/s、更には15〜18m/s、更には16〜17m/s程度で設定することができる。   The second-stage wind sorting is preferably carried out for the purpose of concentrating the synthetic resins and the substrate from the electronic / electric equipment part waste from which the powder and film-like part waste have been removed. For example, the air volume of the second-stage wind sorting can be set at 5 to 20 m / s, more preferably 10 to 18 m / s, further 15 to 18 m / s, and further about 16 to 17 m / s.

第1段階目の風力選別と第2段階目の風力選別との間にスリット状の篩を有する篩別機を用いて篩別処理を更に行うことが更に好ましい。第1段階目の風力選別の後に篩別処理を行うことにより、紛状物とフィルム状部品屑が除去された電子・電気機器部品屑から、線屑などの線状の部品屑を取り除くことができるため、第2段階目の風力選別において、処理対象物中の合成樹脂類及び基板の含有率をより高めることができるとともに、線屑の混入による後段の選別処理の負荷を低減することができる。   More preferably, the sieving process is further performed using a sieving machine having a slit-like sieve between the first-stage wind sorting and the second-stage wind sorting. By performing a sieving process after the first-stage wind power sorting, it is possible to remove linear part waste such as wire waste from electronic / electric equipment part waste from which powder and film-like part waste have been removed. Therefore, in the second-stage wind power sorting, the content of the synthetic resins and the substrate in the processing object can be further increased, and the load of the subsequent sorting processing due to the mixing of wire scraps can be reduced. .

このようにして得られた合成樹脂類及び基板の含有率が濃縮された処理対象物に対してそのまま例えばメタルソータ等を用いて金属物及び非金属物の選別を行った場合、非金属物が除去されにくく、金属物を高効率で回収できない場合があることが分かった。   When the metallic resin and the non-metallic material are selected using the metal sorter or the like as they are on the processing objects in which the content of the synthetic resins and the substrate thus obtained is concentrated, the non-metallic material is removed. It has been found that metal objects may not be collected with high efficiency.

本発明の実施の形態に係る電子・電気機器部品屑の処理方法では、後述する色彩選別機1を用いることにより、合成樹脂類、IC等のパーツ、メタル類、基板の混在する部品屑の中から基板屑を選択的に取り除くことができる。これにより、その後のメタルソータにおける処理における金属物の濃縮が容易になることを本発明者らが見出したものである。   In the electronic / electrical equipment part waste processing method according to the embodiment of the present invention, by using a color sorter 1 described later, the part waste such as synthetic resin, IC parts, metals, and substrates is mixed. The substrate waste can be selectively removed from the substrate. As a result, the present inventors have found that it is easy to concentrate the metal in the subsequent processing in the metal sorter.

本発明の実施の形態に係る電子・電気機器部品屑の処理方法においては、電子・電気機器部品屑中の基板屑を除去した後の電子・電気機器部品屑に対し、メタルセンサー、カメラユニット、エアーバルブ、コンベアを備えるメタルソータを用いて電子・電気機器部品屑中の金属物又は非金属物を分離する分離工程において、メタルソータが備えるメタルセンサーが金属物と判別するものと非金属物と判別する物の個数比(金属物/非金属物)が2.0以下となるように、色彩選別機1を用いて、電子・電気機器部品屑の中から金属物を含む基板屑を選択的に除去する。これにより、本実施形態に係る色彩選別機1による選別処理の後のメタルソータを用いた処理における金属物の濃縮が容易になる。   In the processing method for electronic / electrical device component waste according to the embodiment of the present invention, the electronic sensor / electronic device component waste after removing the substrate waste in the electronic / electrical device component waste, a metal sensor, a camera unit, In the separation process of separating metal or non-metal in electronic / electric equipment parts waste using a metal sorter equipped with an air valve and a conveyor, the metal sensor provided in the metal sorter discriminates between metal and non-metal. Using the color sorter 1, the substrate waste containing metal objects is selectively removed from the electronic / electric equipment component waste so that the number ratio of the objects (metal / non-metal) is 2.0 or less. To do. This facilitates the concentration of metal in the process using the metal sorter after the sorting process by the color sorter 1 according to the present embodiment.

図1に本発明の実施の形態に係る色彩選別機1の一例を示す。本発明の実施の形態に係る色彩選別機1は、処理対象物に必要に応じて振動を与えるフィーダ(図示せず)と、フィーダから供給される処理対象物を搬送するコンベア2と、コンベア2から放出された落下軌跡上で処理対象物の表裏両面の色彩を識別する少なくとも2台のカメラユニット3a、3bと、カメラユニット3a、3bが除去対象として検出する検出物に対して空気を吹き付け、検出物を除去物側の容器へと撃ち落とすエアノズル5とを備える。   FIG. 1 shows an example of a color sorter 1 according to an embodiment of the present invention. A color sorter 1 according to an embodiment of the present invention includes a feeder (not shown) that applies vibration to a processing object as necessary, a conveyor 2 that conveys the processing object supplied from the feeder, and a conveyor 2. At least two camera units 3a and 3b that identify the colors of the front and back surfaces of the processing object on the fall trajectory emitted from the camera, and air is blown against the detection object detected by the camera units 3a and 3b as a removal target, And an air nozzle 5 that shoots the detected object down to the container on the removed object side.

色彩選別機1は更に、エアノズルから噴出させる空気の圧力(エア圧力)を調整するコントローラ(図示せず)、カメラユニット3a、3bの近傍に設けられ、カメラユニット3a、3bの視界を照らすカメラユニット照明4a、4b、コンベア2の下方に設けられ、処理対象物中の金属物を検知するメタルセンサー8、処理対象物の位置を検出可能な近赤外線センサ6、近赤外線センサ6の近傍に設けられた近赤外線センサ照明7等を更に含んでいてもよい。   The color sorter 1 is further provided with a controller (not shown) for adjusting the pressure (air pressure) of air ejected from the air nozzle, in the vicinity of the camera units 3a and 3b, and a camera unit that illuminates the field of view of the camera units 3a and 3b. Illumination 4a, 4b, provided below conveyor 2, metal sensor 8 for detecting a metal object in the processing object, near infrared sensor 6 capable of detecting the position of the processing object, provided in the vicinity of near infrared sensor 6. Further, near-infrared sensor illumination 7 or the like may be included.

選別処理対象物である基板は、表裏両面がソルダーレジストで覆われているものと、片面のみソルダーレジストで覆われているものがある。一般的に、ソルダーレジストで覆われた面は緑色であり、ソルダーレジストで覆われていない面は茶色である。色彩選別機1で検出色を緑色に設定することによりソルダーレジストで覆われた面を検出し基板を選択的に除去することができる。   There are two types of substrates, which are objects to be sorted, that are both front and back covered with a solder resist and one that is covered only with a solder resist. Generally, the surface covered with the solder resist is green, and the surface not covered with the solder resist is brown. By setting the detection color to green with the color sorter 1, the surface covered with the solder resist can be detected and the substrate can be selectively removed.

カメラユニットが処理対象物の表面又は裏面の一方のみの色彩を識別する位置にある従来の装置では、処理対象物の表面及び裏面の両面の色彩を識別するように検出色を設定する必要がある。このような従来のカメラユニットにより片方のみソルダーレジストで覆われている基板を検出する場合は、検出色をソルダーレジストで覆われている面の緑色と、ソルダーレジストで覆われていない面の茶色に設定する必要があるが、茶色や汚れた白色のプラスチック(合成樹脂類)を基板と検知するような誤検知が生じやすい。   In the conventional apparatus in which the camera unit is positioned to identify only one color of the front or back surface of the processing object, it is necessary to set the detection color so as to identify the colors of both the front and back surfaces of the processing object. . When a conventional camera unit detects a substrate that is covered with solder resist only on one side, the detection color is green on the surface covered with the solder resist and brown on the surface not covered with the solder resist. Although it is necessary to set, a false detection such as detecting brown or dirty white plastic (synthetic resins) as a substrate is likely to occur.

一方で、図1に示す色彩選別機1のように、カメラユニット3a、3bが処理対象物の表面及び裏面の両面の色彩を識別する位置にある場合は、処理対象物の表面又は裏面の一方のみの色彩を識別するようにカメラユニット3a、3bの検出色が設定されれば良い。カメラユニット3a、3bが、片方のみソルダーレジストで覆われた基板を検出する場合は、検出色をソルダーレジストで覆われている面の緑色に設定することで、プラスチック(合成樹脂類)の誤検知を抑えながら基板を選択的に除去することができる。検出色はソルダーレジストの現在の標準色である緑色とすることが好ましいが、選別する基板の色調に応じて検出色を追加してもよい。例えば、選別する基板の色に応じて、赤色、青色、黒色、白色などを検出色として追加してもよい。   On the other hand, when the camera units 3a and 3b are in positions for identifying both the front and back colors of the processing object as in the color sorter 1 shown in FIG. 1, one of the front and back surfaces of the processing object is displayed. The detection colors of the camera units 3a and 3b may be set so as to identify only the colors. When the camera units 3a and 3b detect a substrate covered with only one of the solder resists, the detection color is set to green on the surface covered with the solder resist, so that the plastic (synthetic resin) is erroneously detected. The substrate can be selectively removed while suppressing. The detection color is preferably green, which is the current standard color of the solder resist, but the detection color may be added according to the color tone of the substrate to be selected. For example, red, blue, black, white, or the like may be added as a detection color according to the color of the substrate to be selected.

本実施形態に係る色彩選別機1によれば、処理対象物の表裏両面の色彩を識別可能な少なくとも2台のカメラユニット3a、3bを、コンベア2の下方及び上方に配置した色彩選別機1を用いることにより、処理対象物それぞれの表裏両面の色彩を検知することが可能となるため、除去対象とする基板以外の誤検知を低減することができる。カメラユニット3a、3bの検知範囲は特に限定されないが、検知範囲があまり大きすぎたり小さすぎたりすると誤検知が生じる場合がある。   According to the color sorter 1 according to the present embodiment, the color sorter 1 in which at least two camera units 3a and 3b that can identify the colors of the front and back surfaces of the processing object are arranged below and above the conveyor 2 is provided. By using it, it becomes possible to detect the colors of both the front and back surfaces of each processing object, and therefore it is possible to reduce false detections other than the substrate to be removed. The detection ranges of the camera units 3a and 3b are not particularly limited, but erroneous detection may occur if the detection range is too large or too small.

電子・電気機器部品屑の中から基板を高い効率で除去するためには、エアノズル5を適正化することも必要である。本実施形態では、例えば図2に示すように、複数の穴からなるエアノズルを用いて、基板屑に対して空気を吹き付け、除去物側の容器へと基板を誘導することが好ましい。   In order to remove the substrate from the electronic / electric equipment component waste with high efficiency, it is also necessary to optimize the air nozzle 5. In the present embodiment, for example, as shown in FIG. 2, it is preferable to blow air to the substrate waste using an air nozzle including a plurality of holes to guide the substrate to the container on the removed object side.

ノズル断面積A及びピッチPは大きすぎると基板以外の部品屑を除去物側へと撃ち落とす恐れがある一方で、小さすぎると基板を適切に除去物側の容器へと撃ち落とせない場合がある。エアノズル5のノズル断面積Aは好ましくは2〜6mm2であり、更に好ましくは3〜5mm2である。エアノズル5のピッチPは好ましくは2〜8mmであり、更に好ましくは3〜6mmである。 If the nozzle cross-sectional area A and the pitch P are too large, there is a risk that component scraps other than the substrate may be shot down to the removed object side, while if too small, the substrate may not be appropriately shot down to the container on the removed object side. The nozzle cross-sectional area A of the air nozzle 5 is preferably 2 to 6 mm 2 , more preferably 3 to 5 mm 2 . The pitch P of the air nozzles 5 is preferably 2 to 8 mm, more preferably 3 to 6 mm.

エアノズル5を用いて基板を適切に除去物側の容器へ分離させるためには、エアノズル5から噴射される空気のスプレー距離を5〜50mmとすることが好ましく、より好ましくは5〜30mmであり、更に好ましくは5〜10mmである。   In order to appropriately separate the substrate into the removed object side container using the air nozzle 5, the spray distance of the air sprayed from the air nozzle 5 is preferably 5 to 50 mm, more preferably 5 to 30 mm, More preferably, it is 5-10 mm.

また、エアノズル5を用いて基板を適切に除去物側の容器へ分離させるためには、エアノズル5から噴射されるエア圧力を0.1〜1.0MPaとすることが好ましく、より好ましくは0.3〜0.7MPaであり、更に好ましくは0.3〜0.5MPaである。なお、図2においてはエアノズル5の穴の形状が矩形を有しているが、矩形には限られず、円形や楕円形、スリット状とすることもできる。   Further, in order to appropriately separate the substrate into the removed object side container using the air nozzle 5, the air pressure ejected from the air nozzle 5 is preferably 0.1 to 1.0 MPa, more preferably 0.8. 3 to 0.7 MPa, and more preferably 0.3 to 0.5 MPa. In FIG. 2, the shape of the hole of the air nozzle 5 has a rectangular shape, but is not limited to a rectangular shape, and may be a circle, an ellipse, or a slit.

このように、本発明の実施の形態に係る電子・電気機器部品屑の処理方法によれば、製錬工程で処理する電子・電気機器部品屑の処理量を増大でき、有価金属を効率的に回収することが可能となる。   Thus, according to the method for processing electronic / electrical equipment component waste according to the embodiment of the present invention, the amount of electronic / electrical device component waste to be processed in the smelting process can be increased, and valuable metals can be efficiently It becomes possible to collect.

本発明は上記の実施形態に限定されるものではなく、その要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、上記実施形態に開示されている複数の構成要素の適宜な組み合わせにより、種々の発明を形成できる。例えば、実施形態に示される全構成要素からいくつかの構成要素を削除してもよい。更に、異なる実施形態の構成要素を適宜組み合わせてもよい。   The present invention is not limited to the above-described embodiment, and can be embodied by modifying the components without departing from the scope of the invention. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment.

最大直径50mm以下に破砕した電子・電気機器部品屑に対して二段階の風力選別と篩別処理を行うことにより、合成樹脂類を25%、基板屑を53%、メタル類を1%、その他21%それぞれ質量比で含む処理対象物を用意した。この処理対象物に対し、本実施形態に係る色彩選別機1を用いて基板を除去する処理を行った。カメラユニットの2台のカメラユニットの識別色を基板のソルダーレジスト色に対応する緑色とし、エアノズルのノズル断面積Aを5mm2、ピッチPを5mm、スプレー距離を20mm、エア圧力を0.3MPaと設定して選別処理を行い、回収物側の容器に回収された回収物中の部品屑の種類を判別したところ、合成樹脂類53%、基板屑9%、メタル類3%、その他35%となり、基板屑を適切に除去することができた。この回収物を更に処理するメタルソータが備えるメタルセンサーが金属物と判別するものと非金属物と判別する物の個数比(金属物/非金属物)を調べたところ、金属物/非金属物の個数比は0.6であった。なお、本実施例に係る色彩選別機で得られた部品屑をコンベアのベルト幅が約0.6mのメタルソータを用いて処理量2.0t/hで処理したところ処理対象物中の合成樹脂類のおよそ66%を除去することができた。 By performing two-stage wind sorting and sieving processing on electronic and electrical equipment parts scraped to a maximum diameter of 50 mm or less, 25% synthetic resin, 53% substrate scrap, 1% metal, etc. An object to be processed containing 21% by mass ratio was prepared. The processing object was subjected to processing for removing the substrate using the color sorter 1 according to the present embodiment. The identification color of the two camera units of the camera unit is green corresponding to the solder resist color of the substrate, the nozzle cross-sectional area A of the air nozzle is 5 mm 2 , the pitch P is 5 mm, the spray distance is 20 mm, and the air pressure is 0.3 MPa. When set and sorted, the type of parts scrap in the recovered material collected in the container on the recovered material side is determined. The result is 53% synthetic resin, 9% substrate waste, 3% metal, and 35% others. The substrate waste could be removed appropriately. When the number ratio (metal / non-metal) of the metal sensor included in the metal sorter for further processing the recovered material is determined as a metal object and the non-metal object, the ratio of metal / non-metal is determined. The number ratio was 0.6. In addition, when the part waste obtained with the color sorter according to the present embodiment was processed at a throughput of 2.0 t / h using a metal sorter having a conveyor belt width of about 0.6 m, synthetic resins in the processing object Approximately 66% of the sample was removed.
