Description

本発明は、原料払出装置及び電子・電気機器部品屑の原料払出方法に関する。 The present invention relates to a raw material dispensing device and a raw material dispensing method for scrap electronic and electrical equipment parts.

近年、資源保護の観点から、廃家電製品・PCや携帯電話等の電子・電気機器部品屑から、有価金属を回収することがますます盛んになってきており、その効率的な回収方法が検討され、提案されている。 In recent years, from the perspective of resource conservation, it has become increasingly common to recover valuable metals from discarded home appliances and scrap parts of electronic and electrical devices such as PCs and mobile phones, and efficient methods for recovering these metals have been studied and proposed.

例えば、特開平9-78151号公報(特許文献1)では、有価金属を含有するスクラップ類を銅鉱石溶錬用自溶炉へ装入し、有価金属を炉内に滞留するマットへ回収させる工程を含む有価金属のリサイクル方法が記載されている。このようなリサイクル方法によれば、銅溶錬自溶炉での銅製錬にスクラップ処理を組み合わせることができるため、有価金属含有率が低いスクラップ類からでも低コストで有価金属を回収することができる。 For example, Japanese Patent Laid-Open Publication No. 9-78151 (Patent Document 1) describes a method for recycling valuable metals that includes a process of charging scrap containing valuable metals into a flash smelting furnace for smelting copper ore and recovering the valuable metals in the matte that remains in the furnace. This recycling method allows scrap processing to be combined with copper smelting in a copper smelting flash smelting furnace, making it possible to recover valuable metals at low cost even from scrap with a low content of valuable metals.

しかしながら、特許文献1に記載されるような銅溶錬自溶炉を用いた処理においては、電子・電気機器部品屑の処理量が増えると、電子・電気機器部品屑を構成する樹脂等の有機物に含まれる炭素成分が増加し、溶錬炉で過還元によるトラブルが発生する場合がある。一方で、電子・電気機器部品屑の処理量は近年増加する傾向にあるため、銅溶錬自溶炉での効率的な処理が望まれている。 However, in processing using a copper smelting flash furnace as described in Patent Document 1, as the processing volume of scrap electronic and electrical equipment parts increases, the carbon content in organic matter such as resins that make up the scrap electronic and electrical equipment parts increases, and problems due to over-reduction in the smelting furnace may occur. On the other hand, the processing volume of scrap electronic and electrical equipment parts has been increasing in recent years, so efficient processing in a copper smelting flash furnace is desired.

銅溶錬自溶炉の過還元によるトラブルを発生する手法の一つとして、電子・電気機器部品屑を銅溶錬自溶炉で処理する前に電子・電気機器部品屑を粉砕処理し、容量を小さくすることが提案されている。例えば、特開2015-123418号公報(特許文献2)では、銅を含む電気・電子機器部品屑を焼却後、所定のサイズ以下に粉砕し、粉砕した電気・電子機器部品屑を銅の溶錬炉で処理することが記載されている。 As one method to prevent problems caused by over-reduction in a copper smelting flash furnace, it has been proposed to crush the scrap electronic and electrical equipment parts to reduce their volume before processing them in a copper smelting flash furnace. For example, JP 2015-123418 A (Patent Document 2) describes incinerating copper-containing scrap electrical and electronic equipment parts, crushing them to a predetermined size or smaller, and processing the crushed electrical and electronic equipment parts in a copper smelting furnace.

しかしながら、電子・電気機器部品屑の処理量が増加することにより、電子・電気機器部品屑に含まれる物質の種類によっては、その後の銅製錬工程での処理に好ましくない物質(製錬阻害物質)が従来よりも多量に投入されることとなる。このような銅製錬工程に装入される製錬阻害物質の量が多くなると、電子・電気機器部品屑の投入量を制限せざるを得なくなる状況が生じる。 However, as the amount of scrap electronic and electrical equipment parts processed increases, depending on the type of substance contained in the scrap electronic and electrical equipment parts, a larger amount of substances that are undesirable for processing in the subsequent copper smelting process (smelting inhibitors) will be added than before. If the amount of smelting inhibitors added to the copper smelting process increases, it will be necessary to limit the amount of scrap electronic and electrical equipment parts added.

天然の鉱石由来の製錬阻害物質も含め、銅製錬の溶錬工程における熱力学的な手法や電解工程における電解液の精製方法については従来から数々の取り組みがされてきたが、天然の鉱石と比較して、製錬阻害物質の含有割合が著しく大きい電子・電気機器部品屑の処理方法には課題が多い。 Numerous efforts have been made in the past regarding thermodynamic methods in the smelting process of copper smelting and methods for refining electrolytes in the electrolysis process, including those that contain smelting inhibitors derived from natural ores, but there are many challenges in processing scrap electronic and electrical equipment parts, which contain a significantly higher proportion of smelting inhibitors compared to natural ores.

本発明者らはこれまで電子・電気機器部品屑から製錬工程で処理するための有価金属を含む処理原料を効率良く選別するとともに、製錬阻害物質を取り除くために好適な種々の選別処理工程及び選別機について鋭意検討を行ってきた。 The inventors have been working to efficiently separate raw materials containing valuable metals from scrap electronic and electrical equipment parts for processing in the smelting process, and have been conducting extensive research into various suitable sorting processes and sorting machines for removing smelting inhibitors.

例えば、電子・電気機器部品屑等の原料を選別機へ搬送する際には、電子・電気機器部品屑を選別機が処理可能な適切な量に調整する必要がある。しかしながら、種々の形状、比重、形状の原料が混在する電子・電気機器部品屑等の原料は、原料同士が特に絡まりやすいため、搬入された原料を常に一定量で払出することが難しい。特に、両サイドの壁に近い原料が盛り上がりやすい。電子・電気機器部品屑の安定的な処理のためには、搬送される原料をより均一に払出することが望まれている。 For example, when transporting raw materials such as electronic and electrical equipment scraps to a sorting machine, it is necessary to adjust the amount of electronic and electrical equipment scraps to an appropriate amount that the sorting machine can process. However, raw materials such as electronic and electrical equipment scraps, which are a mixture of materials with various shapes, specific gravities, and shapes, tend to become tangled, making it difficult to always dispense a constant amount of the raw materials that are brought in. In particular, the raw materials near the walls on both sides tend to pile up. For stable processing of electronic and electrical equipment scraps, it is desirable to dispense the transported raw materials more uniformly.

上記課題を鑑み、本開示は、種々の形状、比重、形状の原料が混在する原料をより均一に払出することが可能な原料払出装置及び電子・電気機器部品屑の原料払出方法を提供する。 In consideration of the above problems, the present disclosure provides a raw material dispensing device and a raw material dispensing method for scrap electronic and electrical equipment parts that can more uniformly dispense raw materials that are a mixture of raw materials of various shapes, specific gravities, and shapes.

上記課題を解決するために本発明者が鋭意検討した結果、原料払出装置から払出される原料を受けるコンベアの搬送面の左右に案内板を設け、案内板により原料の一部を滞留させることによりコンベア上に払出される原料の高さを平均化できることが分かった。 As a result of extensive research by the inventors to solve the above problems, it was discovered that by providing guide plates on the left and right sides of the conveyor's transport surface that receives the raw materials dispensed from the raw material dispenser, and by using the guide plates to retain some of the raw materials, it is possible to average out the height of the raw materials dispensed onto the conveyor.

本発明の実施の形態は一側面において、原料を払出するための払出口を一端に備え、原料を貯留する貯留部と、貯留部の底面に配置され、払出口へ向けて原料を搬送し、貯留部の外へと払出す払出部と、払出部の上方から下方へと延びる複数の支柱を備え、該支柱により原料の一部を抑えて払出口から払出される原料の量を調整する調整部とを備える原料払出部と、払出口から払出された原料を搬送する搬送面を備えるコンベアと、コンベアの搬送方向に離間して配置され、搬送面の両端からそれぞれ互い違いに突出するように、コンベア上に配置された2以上の案内板とを備える原料払出装置が提供される。 In one aspect, an embodiment of the present invention provides a raw material dispensing device that includes a storage section that stores raw materials and has a dispensing outlet at one end for dispensing raw materials, a dispensing section that is arranged on the bottom surface of the storage section and transports the raw materials toward the dispensing outlet and dispenses them out of the storage section, a raw material dispensing section that includes a plurality of supports extending from above to below the dispensing section and an adjustment section that uses the supports to hold down a portion of the raw materials to adjust the amount of raw material dispensed from the dispensing outlet, a conveyor that includes a transport surface that transports the raw materials dispensed from the dispensing outlet, and two or more guide plates that are arranged on the conveyor at a distance from each other in the conveying direction of the conveyor and that protrude alternately from both ends of the transport surface.

本発明の実施の形態は別の一側面において、原料を払出するための払出口を一端に備え、原料を貯留するための貯留部内に電子・電気機器部品屑を貯留し、貯留部の底面に配置された払出部により電子・電気機器部品屑を払出口へと搬送し、払出部の上方から下方へと延びる複数の支柱の支柱間の間隔及び高さをそれぞれ調整することにより、電子・電気機器部品屑の一部を抑えながら、電子・電気機器部品屑を払出部の下方に配置されたコンベアへと払出し、コンベアの搬送面の両端から搬送方向に沿って互い違いに突出するように、コンベア上に配置された2以上の案内板へ原料を接触させることにより原料の流れを蛇行させて原料の高さを平均化することを含む電子・電気機器部品屑の原料払出方法が提供される。 In another aspect of the embodiment of the present invention, a method for dispensing scrap electronic and electrical equipment parts includes storing scrap electronic and electrical equipment parts in a storage section for storing raw materials, having a discharge port at one end for dispensing raw materials, transporting the scrap electronic and electrical equipment parts to the discharge port by a discharge section arranged on the bottom surface of the storage section, dispensing the scrap electronic and electrical equipment parts to a conveyor arranged below the discharge section while suppressing some of the scrap electronic and electrical equipment parts by adjusting the spacing and height of multiple supports extending from above to below the discharge section, and bringing the raw materials into contact with two or more guide plates arranged on the conveyor so as to protrude alternately from both ends of the conveying surface of the conveyor in the conveying direction, thereby causing the flow of the raw materials to meander and averaging the height of the raw materials.

本開示によれば、種々の形状、比重、形状の原料が混在する原料をより均一に払出することが可能な原料払出装置及び電子・電気機器部品屑の原料払出方法が提供できる。 The present disclosure provides a raw material dispensing device and a raw material dispensing method for scrap electronic and electrical equipment parts that can more uniformly dispense raw materials that are a mixture of raw materials of various shapes, specific gravities, and shapes.

In the following description of the drawings, identical or similar parts are given the same or similar reference numerals. Note that the embodiments shown below are examples of devices and methods for embodying the technical idea of this invention, and the technical idea of this invention does not specify the structure, arrangement, etc. of the components as described below.

(原料払出装置)
本発明の実施の形態に係る原料払出装置100は、図1に示すように、原料払出部10と、原料払出部10から払出された原料40を搬送する搬送面50を備えるコンベア5と、コンベア5の搬送方向に離間して配置され、搬送面50の両端からそれぞれ互い違いに突出するように、コンベア5上に配置された2以上の案内板8a、8bとを備える。
(Raw material dispensing device)
As shown in FIG. 1, a raw material dispensing device 100 according to an embodiment of the present invention comprises a raw material dispensing section 10, a conveyor 5 having a conveying surface 50 for conveying raw materials 40 dispensed from the raw material dispensing section 10, and two or more guide plates 8a, 8b arranged on the conveyor 5 so as to be spaced apart in the conveying direction of the conveyor 5 and to protrude alternately from both ends of the conveying surface 50.

原料払出部10は、原料40を貯留する貯留部1と、原料40を貯留部1の外へと払出す払出部2と、原料40を抑えて払出口11から払出される原料40の量を調整する調整部3とを備える。 The raw material dispensing unit 10 includes a storage unit 1 that stores raw material 40, a dispensing unit 2 that dispenses raw material 40 out of the storage unit 1, and an adjustment unit 3 that holds back raw material 40 and adjusts the amount of raw material 40 dispensed from the dispensing outlet 11.

貯留部1は、原料40を払出するための払出口11を一端に備える。貯留部1は、背面12と、互いに対向する側面13、14と、底面15とを備える。貯留部1の底面15上には原料40が配置される。払出部2は貯留部1の底面15に配置されている。払出部2としてはいわゆる床板移動式の定量供給機が用いられる。 The storage section 1 has a dispensing outlet 11 at one end for dispensing the raw material 40. The storage section 1 has a back surface 12, opposing side surfaces 13 and 14, and a bottom surface 15. The raw material 40 is placed on the bottom surface 15 of the storage section 1. The dispensing section 2 is placed on the bottom surface 15 of the storage section 1. A so-called movable-bed type constant volume feeder is used as the dispensing section 2.

例えば、払出部2は、貯留部1の底面15に配置され、貯留部1の背面12側から払出口11側に互いに間隔を空けて略平行に延びる複数のガイド21と、ガイド21を覆うようにガイド21上にそれぞれ配置され、ガイド21に沿って貯留部1内を払出口11と背面12との間で往復することにより、原料40を貯留部1の外へ払い出す複数のスラット22と、複数のスラット22の往復移動を駆動する駆動装置(不図示)とを備える。 For example, the dispensing section 2 is provided with a plurality of guides 21 arranged on the bottom surface 15 of the storage section 1 and extending approximately parallel to each other at intervals from the rear surface 12 side of the storage section 1 to the dispensing outlet 11 side, a plurality of slats 22 arranged on the guides 21 so as to cover the guides 21 and dispensing the raw material 40 out of the storage section 1 by reciprocating along the guides 21 between the dispensing outlet 11 and the rear surface 12 within the storage section 1, and a drive device (not shown) that drives the reciprocating movement of the plurality of slats 22.

払出部2が備える複数のスラット22が、払出口11と背面12との間で往復運動することによって、貯留部1内に貯留された原料40が、徐々に払出口11側へ押し出されて、払出口11の外へと払出される。 The raw material 40 stored in the storage section 1 is gradually pushed toward the dispensing outlet 11 and dispensed out of the dispensing outlet 11 by the reciprocating motion of the multiple slats 22 provided in the dispensing section 2 between the dispensing outlet 11 and the back surface 12.

図1に示すように、払出口11側付近の払出部2の上方には、払出部2の上方から下方へと延びる複数の支柱31を備え、複数の支柱31により原料40の一部を抑えて貯留部1の外へ払出される原料40の量を調整するための調整部3が設けられている。調整部3は、貯留部1の対向する側面13と側面14との間に固定され、複数の支柱31を固定する支柱固定部32と、支柱31の貯留部1の底面15からの高さを調整する高さ調整部(不図示)とを備える。 As shown in FIG. 1, above the dispensing section 2 near the dispensing outlet 11 side, there is provided an adjustment section 3 that includes multiple pillars 31 extending downward from above the dispensing section 2, and that adjusts the amount of raw material 40 dispensed out of the storage section 1 by holding back a portion of the raw material 40 with the multiple pillars 31. The adjustment section 3 is fixed between the opposing side surfaces 13 and 14 of the storage section 1, and includes a pillar fixing section 32 that fixes the multiple pillars 31, and a height adjustment section (not shown) that adjusts the height of the pillars 31 from the bottom surface 15 of the storage section 1.

支柱固定部32は、背面12側から払出口11側へ払出される原料40の圧力を受けて複数の支柱31が払出口11側に移動しないように、複数の支柱31を所定の位置に固定することができる構造であれば、図1の例には限定されず任意の構造を有することができる。 The pillar fixing portion 32 can have any structure, not limited to the example shown in FIG. 1, so long as it is capable of fixing the multiple pillars 31 in a predetermined position so that the multiple pillars 31 do not move toward the discharge outlet 11 side under the pressure of the raw material 40 discharged from the back surface 12 side toward the discharge outlet 11 side.

図1の例では、側面13と側面14との間に柱状の支柱固定部32が架け渡され、支柱固定部32が備える複数の開口部内に、複数の支柱31がそれぞれ収容されるようになっている。そして、開口部付近の支柱固定部32に設けられた、ボルト、フランジ等の固定具(不図示)で構成される高さ調整部によって、支柱31の高さが任意の高さに固定されるようになっている。 In the example of FIG. 1, a column-shaped support fixing part 32 is bridged between side surface 13 and side surface 14, and a number of supports 31 are accommodated in a number of openings provided in support fixing part 32. The height of support 31 can be fixed to any height by a height adjustment part consisting of a fastener (not shown) such as a bolt or flange provided on support fixing part 32 near the opening.

支柱固定部32上には、床、即ちスラット22の上面からの各支柱31の高さを検知するための高さ検知部33が設けられていてもよい。高さ検知部33としては例えばマイクロ波センサー等を用いることができる。高さ検知部33の検知結果に基づいて支柱31の高さを調整する高さ調整部(不図示)を制御することによって、原料40の収容状態に応じて支柱31の高さを変更可能な制御装置34を備えていてもよい。 A height detection unit 33 for detecting the height of each pillar 31 from the floor, i.e., the upper surface of the slat 22, may be provided on the pillar fixing unit 32. A microwave sensor or the like may be used as the height detection unit 33. A control device 34 may be provided that can change the height of the pillar 31 according to the storage state of the raw material 40 by controlling a height adjustment unit (not shown) that adjusts the height of the pillar 31 based on the detection result of the height detection unit 33.

複数の支柱31の間隔d1、d2および床からの高さH1、H2は、払出する原料40の種類によって調整することができる。特に、種々の形状、比重、形状の原料40が混在する電子・電気機器部品屑等の原料40を、原料40の滞りがなく円滑に搬送して払出するために鋭意検討した結果、複数の支柱31のそれぞれの間隔及び間隔比と高さ及び高さの比をそれぞれ調整することが有効であることが分かった。 The spacing d1, d2 between the multiple support columns 31 and the heights H1, H2 from the floor can be adjusted depending on the type of raw material 40 to be dispensed. In particular, after careful consideration was given to smoothly transport and dispense raw material 40 such as scrap electronic and electrical equipment parts, which contain a mixture of raw materials 40 of various shapes, specific gravities, and configurations, it was found that it is effective to adjust the spacing and spacing ratio of each of the multiple support columns 31, as well as the heights and height ratios.

電子・電気機器部品屑等のような種々の形状、比重、形状の原料40を、図1の原料払出装置100に収容すると、払出作業が進行するにつれて、側面13、14付近の原料40が上手く払出されずに停滞し、停滞した原料40に更に中央部の原料40が絡まってうまく排出されずに詰まり(ブリッジ)が生じる場合がある。 When raw materials 40 of various shapes, specific gravities, and configurations, such as electronic and electrical equipment part scraps, are stored in the raw material dispensing device 100 of FIG. 1, as the dispensing operation progresses, the raw materials 40 near the sides 13 and 14 cannot be discharged properly and become stagnant. The stagnant raw materials 40 may become entangled with the raw materials 40 in the center, preventing them from being discharged properly and causing blockages (bridges).

本実施形態では、図2に示すように、貯留部1の側面13、14付近の原料40の詰まりを抑制するために、貯留部1の側面13、14に最も近い支柱31と貯留部1の側面13、14との間の間隔d1と貯留部1の中央部の支柱31間の間隔の最も狭い間隔(d2)の比(d1/d2)を調整するとともに貯留部1の側面13、14に最も近い支柱31の床からの高さ(H1)と貯留部1の側面13、14に最も近い支柱31以外の支柱31の床からの最小の高さ(H2)の比(H1/H2)を調節することが好ましい。 In this embodiment, as shown in FIG. 2, in order to suppress clogging of the raw material 40 near the sides 13, 14 of the storage section 1, it is preferable to adjust the ratio (d1/d2) of the distance d1 between the pillar 31 closest to the sides 13, 14 of the storage section 1 and the side 13, 14 of the storage section 1 to the narrowest distance (d2) between the pillars 31 in the center of the storage section 1, and to adjust the ratio (H1) of the height from the floor of the pillar 31 closest to the sides 13, 14 of the storage section 1 to the minimum height (H2) from the floor of the pillar 31 other than the pillar 31 closest to the sides 13, 14 of the storage section 1.

より具体的には、d1≦d2の場合、H1/H2=3~10となるように複数の支柱31を配置することが好ましく、d1>d2の場合、H1/H2=0.5~3となるように複数の支柱31を配置することが好ましい。これにより、種々の形状、比重、形状の原料40が混在する原料40を一定量毎に効率よく払出することが可能な原料払出装置100が得られる。 More specifically, when d1≦d2, it is preferable to arrange multiple supports 31 so that H1/H2 = 3 to 10, and when d1>d2, it is preferable to arrange multiple supports 31 so that H1/H2 = 0.5 to 3. This makes it possible to obtain a raw material dispensing device 100 that can efficiently dispense a fixed amount of raw material 40 that is a mixture of raw materials 40 of various shapes, specific gravities, and shapes.

支柱31の数は限定されないが、例えば3~10本、好ましくは3~8本、更に好ましくは4~6本とすることができる。各支柱31の底面15からの高さは原料40の状態に応じて調整される。なお、本実施形態において「中央部の支柱31の間隔d2」とは、貯留部1の水平方向において中心に最も近い支柱31とその次に中心に近い支柱31との間隔を意味する。 The number of pillars 31 is not limited, but may be, for example, 3 to 10, preferably 3 to 8, and more preferably 4 to 6. The height of each pillar 31 from the bottom surface 15 is adjusted according to the state of the raw material 40. In this embodiment, the "distance d2 between the pillars 31 in the center" refers to the distance between the pillar 31 closest to the center of the storage section 1 in the horizontal direction and the pillar 31 next closest to the center.

支柱31の高さは、原料40の滞留状態に応じて水平方向に沿ってそれぞれ異なる高さとなるようにぞれぞれの高さを変更してもよい。例えば、図3に示すように、中央部の支柱31付近に原料40が固まって払出が難しくなっている場合には、中央部の支柱31の高さを側面13、14側の支柱31の高さよりも高くするか、或いは、側面13、14に最も近い支柱31の側面13、14からの距離を長くして、中央付近からの原料40の払出が行われやすくなるようにすることもできる。以下に限定されるものではないが、本実施形態では、例えば貯留部1の側面13から側面14までの長さは例えば300m~500mとすることができ、払出部2上面から支柱31の下端部までの高さHは500mm~800mmとすることができる。 The height of the pillars 31 may be changed so that they are different heights along the horizontal direction depending on the retention state of the raw material 40. For example, as shown in FIG. 3, if the raw material 40 is solidified near the central pillar 31 and is difficult to dispense, the height of the central pillar 31 may be made higher than the height of the pillars 31 on the side surfaces 13 and 14, or the distance from the side surfaces 13 and 14 of the pillars 31 closest to the side surfaces 13 and 14 may be increased to make it easier to dispense the raw material 40 from near the center. Although not limited to the following, in this embodiment, for example, the length from the side surface 13 to the side surface 14 of the storage section 1 can be, for example, 300 m to 500 m, and the height H from the top surface of the dispensing section 2 to the lower end of the pillar 31 can be 500 mm to 800 mm.

また、図1の例では、貯留部1内の原料40を抑えながら貯留部1の外へ払い出される原料40の量を調整する調整部3が、払出口11側に一か所、設けられる例が記載されているが、払出口11側から背面12側へ向けて一定の間隔を空けて調整部3を複数段、好ましくは2段以上、更には3段以上設けることが好ましい。調整部3を複数段設け、各調整部3が備える支柱31の高さをそれぞれ調整することで、原料40の滞留を抑制しながら原料40の払出がより円滑に行われるように、制御することができる。特に、原料調節部前の原料40の高さが、H2に対して、1.3倍から5倍であればよく、3倍以下がより好ましい。 In the example of FIG. 1, an adjustment unit 3 that adjusts the amount of raw material 40 dispensed out of the storage unit 1 while suppressing the amount of raw material 40 in the storage unit 1 is provided at one location on the outlet 11 side, but it is preferable to provide multiple adjustment units 3 at regular intervals from the outlet 11 side toward the back surface 12 side, preferably two or more stages, and even three or more stages. By providing multiple adjustment units 3 and adjusting the height of the support 31 of each adjustment unit 3, it is possible to control the dispensing of raw material 40 more smoothly while suppressing the retention of raw material 40. In particular, the height of raw material 40 before the raw material adjustment unit may be 1.3 to 5 times H2, and more preferably 3 times or less.

図1に示す原料払出部10を用いて原料40の払出を行う場合は、まず、貯留部1の底面15上に原料40を配置し、図示しない駆動装置により払出部2を駆動させる。具体的には、図4(a)に示すように、まず、全てのスラット22が払出口11側から背面12側へと移動する。払出口11側付近にはスラット22の下方に配置されたガイド21が露出される。次に、図4(b)に示すように、すべてのスラット22が、背面12側に収容された原料40を保持しながら背面12側から払出口11側へと移動することにより、原料40が払出口11側へと搬送される。 When dispensing raw material 40 using the raw material dispensing unit 10 shown in FIG. 1, first, the raw material 40 is placed on the bottom surface 15 of the storage unit 1, and the dispensing unit 2 is driven by a drive device (not shown). Specifically, as shown in FIG. 4(a), first, all of the slats 22 move from the dispensing outlet 11 side to the back surface 12 side. The guides 21 arranged below the slats 22 are exposed near the dispensing outlet 11 side. Next, as shown in FIG. 4(b), all of the slats 22 move from the back surface 12 side to the dispensing outlet 11 side while holding the raw material 40 stored on the back surface 12 side, thereby transporting the raw material 40 to the dispensing outlet 11 side.

図4(c)に示すように、スラット22の一部が払出口11側から背面12側へ移動する。本実施形態では隣接する3本のスラット22が一セットとなって動作する例を示すが、この例には限定されないことは勿論である。図4(c)の例では、最も左側のスラット22と左から4番目のスラット22が背面12側へ移動し、最も左側のガイド21と左から4番目のガイド21上に原料40が保持される。 As shown in FIG. 4(c), some of the slats 22 move from the outlet 11 side to the back surface 12 side. In this embodiment, an example is shown in which three adjacent slats 22 operate as a set, but this is of course not limited to this example. In the example of FIG. 4(c), the leftmost slat 22 and the fourth slat 22 from the left move to the back surface 12 side, and the raw material 40 is held on the leftmost guide 21 and the fourth guide 21 from the left.

図4(c)で背面12側に移動したスラット22に隣接するスラット22、即ち、図5(a)に示すように、左から2番目のスラット22と4番目のスラット22が、払出口11側から背面12側へと移動する。原料40の一部はガイド21上で保持される。図5(b)に示すように、左から3番目のスラット22と6番目のスラット22が背面12側へと移動する。全てのスラット22が背面12側へ移動した後、図5(c)に示すように、全てのスラット22が払出口11側へと移動する。この移動により、ガイド21上の原料40が払出口11側へ押しこまれて、払出口11の下方に配置されたコンベア5の搬送面50上に原料40が払出される。 The slats 22 adjacent to the slats 22 that have moved to the rear surface 12 side in FIG. 4(c), that is, the second slat 22 and the fourth slat 22 from the left as shown in FIG. 5(a), move from the outlet 11 side to the rear surface 12 side. A part of the raw material 40 is held on the guide 21. As shown in FIG. 5(b), the third slat 22 and the sixth slat 22 from the left move to the rear surface 12 side. After all the slats 22 have moved to the rear surface 12 side, all the slats 22 move to the outlet 11 side as shown in FIG. 5(c). This movement pushes the raw material 40 on the guide 21 to the outlet 11 side, and the raw material 40 is discharged onto the conveying surface 50 of the conveyor 5 arranged below the outlet 11.

図1に示す原料払出部10によれば、図4(a)~図5(c)の動作を複数回繰り返すことにより、スラット22の往復運動が終わるごとに、ほぼ一定量の原料40が搬送面50上へ分配されるため、払出量を常時ほぼ一定にすることが可能となる。 With the raw material dispensing unit 10 shown in Figure 1, by repeating the operations of Figures 4(a) to 5(c) multiple times, a nearly constant amount of raw material 40 is distributed onto the conveying surface 50 each time the slats 22 complete their reciprocating motion, making it possible to keep the dispensing amount nearly constant at all times.

さらに図6に示すように、コンベア5の搬送面50上の原料40の載置状態に着目すると、スラット22を用いた1回の払出により払出される原料40の量が、コンベア5の搬送面50の搬送方向に沿って異なる場合がある。1回の払出により払出される原料40の量が、コンベア5の搬送面50の搬送方向に沿って異なると、コンベア5の搬送先にある選別機等に投入される原料40の量が経時的に変化し、これにより選別処理の安定性が損なわれる可能性がある。 Furthermore, as shown in FIG. 6, when attention is paid to the placement state of the raw materials 40 on the conveying surface 50 of the conveyor 5, the amount of raw materials 40 dispensed in one dispensing using the slats 22 may vary along the conveying direction of the conveying surface 50 of the conveyor 5. If the amount of raw materials 40 dispensed in one dispensing varies along the conveying direction of the conveying surface 50 of the conveyor 5, the amount of raw materials 40 fed into a sorting machine or the like at the destination of the conveyor 5 will change over time, which may cause the stability of the sorting process to be compromised.

本実施形態に係る原料払出装置100によれば、図1に示すように、コンベア5上に、コンベア5の搬送方向に離間する2以上の案内板8a、8bが配置される。図7(a)に示すように、この案内板8a、8bに、原料払出部10から払出される原料40を接触させ、原料40の流れを搬送方向に対して蛇行させるように原料40の搬送方向を調整することで、原料40の偏りを平均化でき、コンベア5によって搬送される原料40の容積を搬送方向において平均化することができる。その結果、種々の形状、比重、形状の原料40が混在する原料40をコンベア5によって搬送する際においても、より更に均一に払出することが可能となる。 According to the raw material dispensing device 100 of this embodiment, as shown in FIG. 1, two or more guide plates 8a, 8b are arranged on the conveyor 5, spaced apart in the conveying direction of the conveyor 5. As shown in FIG. 7(a), the raw material 40 dispensed from the raw material dispensing section 10 is brought into contact with the guide plates 8a, 8b, and the conveying direction of the raw material 40 is adjusted so that the flow of the raw material 40 meanders in the conveying direction, thereby averaging out the bias of the raw material 40 and averaging the volume of the raw material 40 conveyed by the conveyor 5 in the conveying direction. As a result, even when raw materials 40 containing a mixture of raw materials 40 of various shapes, specific gravities, and configurations are conveyed by the conveyor 5, they can be dispensed more uniformly.

図7(a)に示すように、案内板8a、8bは、搬送面50の両端からそれぞれ互い違いに搬送面50の中央部に向かって突出するように配置されている。図7(a)の例では、案内板8a、8bが、搬送方向とほぼ垂直な向きに延在するように配置されているが、案内板8a、8bの搬送面中央部側の一端が搬送方向に向くように案内板8a、8bを搬送方向垂直方向に対してやや傾斜させて配置することにより、案内板8a、8b付近の原料40の詰まりを抑制しながら原料40をより円滑に搬送できる。 As shown in FIG. 7(a), the guide plates 8a, 8b are arranged so that they protrude alternately from both ends of the conveying surface 50 toward the center of the conveying surface 50. In the example of FIG. 7(a), the guide plates 8a, 8b are arranged so that they extend in a direction almost perpendicular to the conveying direction, but by arranging the guide plates 8a, 8b at a slight incline with respect to the direction perpendicular to the conveying direction so that one end of the guide plates 8a, 8b on the central side of the conveying surface faces the conveying direction, the raw material 40 can be conveyed more smoothly while preventing clogging of the raw material 40 near the guide plates 8a, 8b.

案内板8a、8bの形状は同一形状とすることにより、案内板8a、8b付近の原料40の詰まりを抑制しながら、種々の形状、比重、形状の原料40が混在する原料40をより均一に払出することが可能となる。即ち、案内板8a、8bは、搬送面50の幅方向に沿った長さw1、w2が、搬送面50の幅方向の長さWに対して20~40%、より好ましくは25~35%とすることにより、案内板8a、8b付近の原料40の詰まりを抑制しながら原料40をより円滑に搬送できる。 By making the guide plates 8a and 8b the same shape, it is possible to more uniformly dispense raw materials 40 that are a mixture of raw materials 40 of various shapes, specific gravities, and shapes while suppressing clogging of the raw materials 40 near the guide plates 8a and 8b. In other words, by making the lengths w1 and w2 of the guide plates 8a and 8b along the width direction of the conveying surface 50 20 to 40%, and more preferably 25 to 35%, of the length W of the conveying surface 50 in the width direction, it is possible to convey the raw materials 40 more smoothly while suppressing clogging of the raw materials 40 near the guide plates 8a and 8b.

図7(b)に示すように、コンベア5端部の搬送面50からの案内板8a、8bの高さh1、h2は、搬送面50上に払出される原料40の最大高さよりも高くすることで、より確実に原料40を蛇行させて平均化することができる。高さh1、h2は、コンベア5の両サイドに設置されたサイドガイド9の高さと同じかそれより低くてよいが、具体的には、250~500mm、一実施態様では300~450mmとすることができる。 As shown in FIG. 7(b), the heights h1 and h2 of the guide plates 8a and 8b from the conveying surface 50 at the end of the conveyor 5 are made higher than the maximum height of the raw material 40 dispensed onto the conveying surface 50, so that the raw material 40 can be more reliably made to meander and be averaged. The heights h1 and h2 may be the same as or lower than the height of the side guides 9 installed on both sides of the conveyor 5, and specifically, may be 250 to 500 mm, and in one embodiment, 300 to 450 mm.

案内板8a、8bの配置する間隔d2は、狭すぎると原料40の詰まりが生じやすくなり詰まった場合の対応がとりにくい等の問題があるが、間隔d2が広い場合には、特に問題はないが、広すぎると設備が長くなるだけなので、設置場所に合わせた長さに調整すればよい。図7(a)に示すように、案内板8a、8bは、搬送方向に300mm以上離間していることが好ましく、500mm以上離間して配置されることがより好ましい。 If the distance d2 between the guide plates 8a and 8b is too narrow, clogging of the raw material 40 occurs easily, making it difficult to deal with clogging. However, if the distance d2 is wide, there is no particular problem, but if it is too wide, the equipment will simply become longer, so the length can be adjusted to suit the installation location. As shown in Figure 7(a), the guide plates 8a and 8b are preferably spaced apart by 300 mm or more in the conveying direction, and more preferably spaced apart by 500 mm or more.

また、原料払出部10に最も近接する案内板8aの距離が近すぎるとばらつきを解消させる余裕がない場合がある。遠すぎる場合には問題ないが、ラインが長くなり好ましくない。図7(a)に示すように、原料払出部10に最も隣接する案内板8aが、原料払出部10から200mm以上離間していることが好ましく、300mm以上離間していることがより好ましい。 In addition, if the guide plate 8a closest to the raw material dispensing unit 10 is too close, there may not be enough room to eliminate the variation. If it is too far away, there is no problem, but the line becomes longer, which is not preferable. As shown in Figure 7(a), the guide plate 8a closest to the raw material dispensing unit 10 is preferably at least 200 mm away from the raw material dispensing unit 10, and more preferably at least 300 mm away.

案内板8a、8bの材質は特に限定されない。種々の形状、比重、形状の原料40が混在する電子・電気機器部品屑を処理対象とする場合は、電子・電気機器部品屑の案内板8a、8b近傍の詰まりを抑制しながらより円滑に搬送するためで、材質は問わない。しかし、電子・電気機器部品屑には金属も含まれ、プラスチック等では摩耗する恐れがあるので、金属製が望ましく、例えば、アルミ製やSUS製で形成されることが好ましい。 The material of the guide plates 8a and 8b is not particularly limited. When processing scrap electronic and electrical equipment parts containing raw materials 40 of various shapes, specific gravities, and shapes, the material is not important, as it is necessary to transport the scrap electronic and electrical equipment parts more smoothly while suppressing clogging near the guide plates 8a and 8b. However, scrap electronic and electrical equipment parts also contain metal, and plastics and the like may wear out, so it is preferable to use metal, for example, and it is preferable to form them from aluminum or SUS.

図8(a)及び図8(b)に示すように、コンベア5上に原料40の高さを調節するための衝突板80を配置したところ、原料40の詰まりが生じ、原料40を円滑に搬送することができなかった。衝突板80をコンベア5上に斜めに配置してみても原料40の詰まりは解消されなかった。 As shown in Figures 8(a) and 8(b), when a collision plate 80 was placed on the conveyor 5 to adjust the height of the raw material 40, the raw material 40 became clogged and could not be transported smoothly. Even when the collision plate 80 was placed at an angle on the conveyor 5, the clogging of the raw material 40 was not resolved.

本実施形態に係る原料払出装置100によれば、コンベア5上に、図7(a)に示すような案内板8a、8bが配置されることによって、種々の形状、比重、形状の原料40が混在する原料40をより均一且つ円滑に搬送することが可能となる。 According to the raw material dispensing device 100 of this embodiment, by arranging guide plates 8a and 8b as shown in FIG. 7(a) on the conveyor 5, it becomes possible to transport raw materials 40, which are a mixture of raw materials 40 of various shapes, specific gravities, and configurations, more uniformly and smoothly.

(電子・電気機器部品屑の処理方法)
図1~図7に示す原料払出装置100は、風力選別機、メタルソータ、カラーソータ、篩別機などの種々の選別機を用いて電子・電気機器部品屑を選別する選別処理を実施する前に、各選別機でそれぞれ処理可能な量ごとに仕分けするための装置として特に好適である。
(Method of Disposal of Scrap Electronic and Electrical Equipment Parts)
The raw material dispensing device 100 shown in Figs. 1 to 7 is particularly suitable as a device for sorting the scrap electronic/electrical device parts into amounts that can be processed by each sorting machine before carrying out a sorting process in which the scrap electronic/electrical device parts are sorted using various sorting machines such as an air sorter, a metal sorter, a color sorter, and a sieving machine.

本実施形態における「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。本実施形態では、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。 In this embodiment, "electronic/electrical device scrap" refers to scraps of crushed electronic/electrical devices such as discarded home appliances, PCs, and mobile phones, which are collected and then crushed to an appropriate size. In this embodiment, the crushing to produce electronic/electrical device scrap may be performed by the processor himself, or crushed items may be purchased from the market.

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よいが、できる限り、部品の形状を損なわない破砕が望ましい。従って、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 may be a shearing method or an impact method, but it is preferable to crush the parts without damaging their shape as much as possible. Therefore, this does not include devices that belong to the category of crushers intended for fine grinding.

電子・電気機器部品屑は、基板、ICやコネクタ等のパーツ、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、最大直径が100mm以下、より典型的には50mm以下となるように破砕されており、且つ部品屑として単体分離されている割合が重量比で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。 Electrical and electronic equipment scraps can be classified into parts such as circuit boards, parts such as ICs and connectors, synthetic resins (plastics) used in housings, wire scraps, metal, film-like parts scraps, powdery materials generated by crushing or pulverization, and others, and can be further classified according to the purpose of processing. Although not limited to the following, in this embodiment, electronic and electrical equipment scraps that have been crushed to a maximum diameter of 100 mm or less, more typically 50 mm or less, and in which the proportion of parts that have been separated into individual pieces as scrap parts is 70% or more by weight can be suitably processed.

これら種々の種類からなる部品屑を、本発明の実施の形態に係る原料払出装置100を用いて一定量毎に払出することにより、種々の形状、比重、形状の原料40が混在する原料40を効率よく払出することが可能となり、その後の選別処理工程に供給するための原料40をよりスムーズに供給することができるようになる。そして、各原料40を所定の順序で処理することにより、例えば、選別物を銅製錬工程に利用する場合には、銅製錬工程での処理に好ましくない物質、例えば、アンチモン(Sb)、ニッケル(Ni)等の元素、樹脂類、アルミニウム(Al)、鉄(Fe)等の製錬阻害物質を極力低減しながら、金、銀、白金、パラジウム、銅を含む有価金属を濃縮した原料40を得ることができる。 By discharging these various types of scrap parts in fixed amounts using the raw material dispensing device 100 according to an embodiment of the present invention, it becomes possible to efficiently discharge the raw materials 40, which are a mixture of raw materials 40 of various shapes, specific gravities, and shapes, and to more smoothly supply the raw materials 40 to be supplied to the subsequent sorting process. By processing each raw material 40 in a predetermined order, for example, when the sorted material is used in a copper smelting process, it is possible to obtain raw materials 40 that are concentrated with valuable metals including gold, silver, platinum, palladium, and copper while minimizing substances that are undesirable for processing in the copper smelting process, such as elements such as antimony (Sb) and nickel (Ni), resins, aluminum (Al), and iron (Fe), which inhibit smelting.

本発明は本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、本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、本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する、或いは各構成要素を適宜組み合わせてもよい。 The present invention is not limited to this embodiment, and the components can be modified without departing from the spirit of the invention. In addition, various inventions can be created by appropriately combining the multiple components disclosed in this embodiment. For example, some components may be deleted from all the components shown in this embodiment, or the components may be appropriately combined.

例えば、図9に示すように、貯留部1から払出された原料40を収容する収容部4が配置され、収容部4を搬送するコンベア5に収容部4の重量を測定する測定部6が配置されていてもよい。測定部6で測定された収容部4の原料40の重量情報は、汎用の計算機等で構成される原料調整部7に送られて、原料調整部7において測定部6による測定結果が解析され、この解析結果に基づいて、複数のスラット22の往復移動を駆動する駆動装置23により、複数のスラット22の往復移動の回数を調整される。これにより、収容部4に収容される原料量をより適正な重量となるように調整される。図9に示すシステムによれば、原料40を処理する選別機の処理能力に応じた適正な量の原料が、収容部4に収容されるように、原料40の種類に応じて調整することができるため、より効率の高い処理が行える。 For example, as shown in FIG. 9, a storage section 4 for storing raw materials 40 dispensed from a storage section 1 may be arranged, and a measuring section 6 for measuring the weight of the storage section 4 may be arranged on a conveyor 5 for transporting the storage section 4. The weight information of the raw materials 40 in the storage section 4 measured by the measuring section 6 is sent to a raw material adjustment section 7 composed of a general-purpose computer or the like, and the measurement results by the measuring section 6 are analyzed in the raw material adjustment section 7. Based on the analysis results, the number of reciprocating movements of the multiple slats 22 is adjusted by a drive device 23 that drives the reciprocating movements of the multiple slats 22. This adjusts the amount of raw materials stored in the storage section 4 to a more appropriate weight. According to the system shown in FIG. 9, the amount of raw materials 40 can be adjusted according to the type of raw materials 40 so that an appropriate amount of raw materials according to the processing capacity of the sorting machine that processes the raw materials 40 is stored in the storage section 4, so that more efficient processing can be performed.
