Description

【０００１】
【発明の属する技術分野】
本発明は、一般廃棄物、産業廃棄物などの廃棄物を種類別に貯留・選別し、効率的に資源化する廃棄物の資源化方法及び資源化施設に関する。
【０００２】
【従来の技術】
一般廃棄物、産業廃棄物などの廃棄物中に廃プラスチックが多く存在するが、その廃プラスチックの中からびんや缶を分離して収集し、塩素含有プラスチックを除去した後、原料や燃料として有効に再利用する資源化技術が注目されており、以下に述べるように実施の方向に進んでいる。
【０００３】
従来の廃棄物資源化方法は、一般廃棄物からびん、缶、プラスチックボトルおよびプラスチック固形物等の固体系プラスチックと、フィルム系プラスチックとを分離収集し、びんは分別し、缶はスチール缶とアルミ缶とに選別し、固体系プラスチックから塩素含有プラスチックを乾式分離により除去し、フィルム系プラスチックから塩素含有プラスチックを湿式分離により除去することにより、再利用するための資源化が行われている。（特開平１０−５７９２９号公報）。
【０００４】
ところで、廃棄物中に含まれる例えば廃プラスチックは、再資源化工場で熱処理などの適宜な再生処理を施すことにより、例えば高炉原料、油、ＰＥＴ粒原料その他の資源に再利用することが可能であり、またびん及び缶についても同様に再処理が可能であるが、運転スケジュール、廃棄物量、廃プラスチックの再利用形態等の要因から、パッカー車などの収集車で収集される廃棄物をそのまま再資源化工場に搬入して直ちに再生処理することが難しく、再生処理前に別の保管場所を選定し一旦貯留しておく必要がある。これは、再資源化工場内であっても同様であって、再生処理前に工場内のある場所に一旦貯留しておく必要がある。
【０００５】
そこで、従来、図１４に示すように選別拠点（資源化施設）１０１が設置され、分離収集された例えば廃プラスチックは、選別拠点１０１内の貯留設備１０２に搬入されて貯留され、破袋機１０３でバラバラにされた後、選別装置１０４により固体系プラスチックとフィルム系プラスチックとに分離され、次工程１０５にて資源として生成される。
【０００６】
また、従来の廃プラスチックの資源化施設としては、廃プラスチックを一旦貯留し、その後、破砕処理する処理施設が提案されている（特開平１１−２７６９２５号公報）。この資源化施設は、排出元から回収する廃プラスチックを貯留する廃プラスチック貯留場（以下、貯留ヤードと呼ぶ）の他、廃プラスチックを破砕処理する硬質プラスチック用破砕機、廃プラスチックを破砕処理する軟質プラスチック用破砕機および大型の廃プラスチックを切断する切断機を設け、廃プラスチックの性質に応じて効率的に破砕処理を行う施設である。
【０００７】
ところで、以上のような廃棄物の資源化方法及びその資源化施設は、貯留ヤードが大きな問題となっている。なぜならば、収集車などで収集した廃棄物を順次貯留ヤードで受入れたとしても、廃プラスチックなどの場合は嵩密度が小さいことから、搬送，運搬だけでなく、保管などについても相当膨大な床占有面積を確保しない限り、短期間に貯留限界に達してしまう。また、廃プラスチックは、嵩の割に投入量、処理量が少ないだけでなく、廃棄物の貯留設備やプラスチック選別設備などを設置する場合、かなり広いスペースが必要となる問題がある。
【０００８】
そこで、従来、地上の廃棄物貯留面積を縮小化する必要性から、図１５に示すように収集車１１１で運び込まれた廃棄物１１２を一時的に貯留する大型地下貯留設備（ピット）１１３が考えられている。
【０００９】
このような施設では、巻上げクレーン設備１１６から吊下されるクラブバケット１１４を用いて、大型地下貯留設備１１３から廃棄物１１２を掴み取って地上の搬送設備１１５や車両などに積み込み、別途の選別設備に搬入し、資源化のための選別処理を行うことになる。
【００１０】
【発明が解決しようとする課題】
しかし、以上のような廃棄物の資源化方法及びその資源化施設では、次のような幾つかの問題が指摘されている。
【００１１】
（１） 従来、廃棄物の中からびん，缶とプラスチック系廃棄物とを分別収集し、それぞれ別々の拠点で貯留したり、さらにびんと缶の選別、びんの色分け、アルミとスチールの材質分け、さらにプラスチック系廃棄物についても前述するように選別することから、多数の貯留拠点や選別拠点を分散的に構築する必要があり、廃棄物を集中的に管理できない問題がある。
【００１２】
（２） また、分散的に多数の貯留拠点や選別拠点を構築する結果、全体の施設の建築コストが高くなる。
【００１３】
（３） 各貯留拠点や各選別拠点にて貯留、選別することから、作業が煩雑となり、資源化のための稼働率が低下する。
【００１４】
（４） さらに、図１５に示すように、廃棄物１１２を分別せずにパッカー車などの収集車１１１で運び込んで大型地下貯留設備１１３に一時的に貯留する場合、収集車１１１による廃棄物の収集、大型地下貯留設備１１３への落下、巻上げクレーン設備１１６から吊下されるクラブバケット１１４による廃棄物１１２の掴み取りなどの際、かなりのびんが割れてしまい、資源化の効率が著しく低下する問題がある。
【００１５】
本発明は上記事情に鑑みてなされたもので、多種類の廃棄物を集中的に資源管理し、作業性及び稼働率の向上を図る廃棄物の資源化方法を提供することにある。
【００１６】
また、本発明の他の目的は、多種類の廃棄物を貯留，選別可能とし、資源の集中的な管理及びびん等の破損をなくして資源化の効率を高める廃棄物の資源化施設を提供することにある。
【００１７】
さらに、本発明の他の目的は、各機能分け設備を最適な状態に配置し、作業効率を高める廃棄物の資源化施設を提供することにある。
【００１８】
【課題を解決するための手段】
（１） 上記課題を解決するために、本発明に係わる廃棄物の資源化方法は、各自治体で定める規則に従って分別収集されたびん，缶等廃棄物と廃プラスチックとを資源化拠点に搬入し資源化する廃棄物の資源化方法であって、前記搬入されるびん，缶等廃棄物を対応する受入れヤードを通して受入れて保管容器に収納梱包し、前記搬入される廃プラスチックを対応する受入れヤードを通して受入れて圧縮梱包する受入れ工程と、この各受入れ工程により受入れた前記保管容器に収納梱包されたびん，缶等廃棄物と圧縮梱包された廃プラスチックとを搬送しながら、予め定めるエリアの高さ方向に順次貯留する貯留工程とを有することにより、びん，缶等廃棄物と廃プラスチックとを集中的に受入れ、少ない貯留面積で効率的に貯留し、管理することが可能となる。
【００１９】
また、本発明に係わる廃棄物の資源化方法は、前記貯留工程で貯留されたびん，缶等廃棄物と廃プラスチックとをそれぞれ異なる選別エリアに搬送し、この搬送されてくるびんをサイズ分け及び色分け選別し、前記搬送されてくる缶を磁気選別と風力選別とによりスチール缶とアルミ缶とに選別するびん，缶用選別工程と、また前記搬送されてくる廃プラスチックを選別するための廃プラ用選別工程と、前記各選別工程で選別されたびん，缶等廃棄物と廃プラスチックを梱包する梱包工程と、この梱包された梱包品の一部または全部を複数のエリアの高さ方向に順次貯留する梱包品貯留工程とを設けることにより、同一の資源化拠点にて、缶の材質、びんのサイズ分け、色分け等の選別が可能になり、また廃プラスチックについてもボトル類とフィルム類とに選別可能となり、作業の稼働率を上げることができる。
【００２０】
さらに、前記各選別工程で選別された資源を梱包する梱包工程と、この梱包された梱包品の一部または全部を複数のエリアの高さ方向に順次貯留する梱包品貯留工程とを設けることにより、缶等廃棄物と廃プラスチックとに対し、一貫した処理体制で資源化できる。
【００２１】
（２） 本発明に係わる廃棄物の資源化施設は、各自治体で定める規則に従って分別収集されたびん，缶等廃棄物と廃プラスチックとを資源化拠点に搬入し資源化する廃棄物の資源化施設であって、前記搬入されるびん，缶等廃棄物を圧縮せずに所定サイズの保管容器に収納し梱包するびん、缶の受入れヤードと廃プラスチックの受入れヤードとを設け、びん，缶等廃棄物と廃プラスチックとをそれぞれ対応する受入れヤードを通して受入れる受入れ設備と、搬送ラインにそって複数のびん，缶用貯留エリアと複数の廃プラ用貯留エリアとが設けられ、当該各貯留エリアの高さ方向に複数の棚が連なる立体式貯留設備と、前記受入れ設備で受入れたびん，缶等廃棄物と廃プラスチックとをそれぞれ個別に前記搬送ラインに沿って搬送しながら、該当する貯留エリアの指定棚に貯留する搬送装置とを備えた構成である。
【００２２】
本発明は以上のような構成とすることにより、搬入されるびん，缶等廃棄物を圧縮せずに所定サイズの保管容器に収納し梱包するびん、缶の受入れヤードを通して受入れるので、びん，缶等廃棄物をまとめた状態で貯留設備に搬送するので、手間をかけずに貯留し易い状態に整理することができる。また、受入れ設備の対応する受入れヤードで受入れたびん，缶等廃棄物と廃プラスチックとを搬送ラインにそって搬送しながら立体式貯留設備の対応するびん，缶用貯留エリア、廃プラ用貯留エリアの指定された棚に順次貯留するので、１個所の立体式貯留設備にびん，缶等廃棄物と廃プラスチックとを集中的に貯留し管理することが可能であり、施設の建築コストを大幅に低減することが可能となる。
さらに、廃プラスチックの受入れヤードとしては、圧縮機及び所定サイズの保管容器を設け、受入れた廃プラスチックを前記圧縮機で圧縮しながら前記保管容器に収納し梱包すれば、さらに貯留時の占有面積を大幅に節減でき、集中的な貯留管理に大きく貢献する。
【００２３】
また、以上の施設の構成に新たに、前記立体式貯留設備に貯留されたびん，缶等廃棄物と廃プラスチックとを前記搬送装置により所定方向に搬出し、所要の種類別に選別するびん，缶用選別設備及び廃プラ用選別設備を設けたことにより、同一施設でびん，缶の選別の他、廃プラスチックの選別も可能になり、計画的に作業を進めることができ、また稼働率の向上を図ることができる。
【００２５】
（３） また、本発明に係わる廃棄物の資源化施設は、各自治体で定める規則に従って分別収集されたびん，缶等廃棄物と廃プラスチックとを資源化拠点に搬入し資源化する廃棄物の資源化施設であって、前記搬入されるびん，缶等廃棄物と廃プラスチックとをそれぞれ隣接する別々の受入れヤードを通して受入れる受入れエリアと、この受入れエリアの受入れ方向と直交行する方向に前記びん，缶等廃棄物と廃プラスチックとを搬送する所要長さの搬送エリアと、この搬送エリアの前記受入れエリアとは反対側の搬送ラインにそってびん，缶等と廃プラスチックとに分けて貯留する貯留エリアと、この貯留エリアに貯留されるびん，缶等と廃プラスチックとにそれぞれ近い貯留エリアの両側方に形成され、それぞれ所要の選別を行うびん，缶用選別エリア及び廃プラ用選別エリアとを配置した構成である。
【００２６】
本発明は以上のような設備の設置エリアを配置することにより、びん，缶等と廃プラスチックとの受入れ、貯留及び選別にとつて作業性の向上を図ることができる。
【００２７】
【発明の実施の形態】
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。
【００２８】
図１は本発明に係わる廃棄物の資源化施設を実現するための資源化方法を説明する工程図である。
【００２９】
一般に、廃棄物の資源化は、各自治体で定める規則に従って分別収集の形態が異なり、例えばびん、缶，ＰＥＴボトルの混合廃棄物と廃プラスチック（ＰＥＴボトルを含むプラスチック系廃棄物）とに分別して収集する場合、びん，缶とＰＥＴボトルとＰＥＴボトルを除く廃プラスチックとに分別して収集する場合、びん，缶と廃プラスチック（ＰＥＴボトルを含むプラスチック系廃棄物）とに分別して収集する場合等がある。従って、予め定める所定のフローに従って廃プラスチックとびん，缶とに分離されていることから、特に廃プラスチックは圧縮機能の有無に係わらず、少なくとも収集車により多少押し込まれて状態で図１に示す資源化拠点１に搬入され、一方、びん，缶は圧縮機能をもたない収集車によって収集時の形状を保った状態で同様に資源化拠点１に搬入される。
【００３０】
なお、廃プラスチックは固体系プラスチックとフィルム系プラスチックとが混在しており、そのうち固体系プラスチックには、プラスチックボトルやプラスチック固形物等が含まれている。プラスチックボトルは、その殆んどがＰＥＴを原料とするいわゆるペットボトルで占めている。プラスチック固形物には、その他のボトルの外、プラスチックケース等の硬質プラスチック製品等がある。一方、フィルム系プラスチックには、包装用ごみ袋等のフィルム状のプラスチック、トレー系プラスチック等が含まれる。
【００３１】
そこで、以上のような廃棄物は、例えばびん、缶とＰＥＴボトルを含む廃プラスチックとに分別搬入されたとき、それぞれエリア分けされた受入れ工程２によって受入れを行う。この受入れ工程２はスペースの有効活用を図る意味から隣接するエリアに設定するのが望ましい。
【００３２】
受入れ工程２で受入れた廃棄物のうち、廃プラスチックは、圧縮装置を備えた圧縮工程３にて所要とする圧縮率で圧縮し保管容器に詰め込んで貯留工程４に移送する。廃プラスチックの嵩比重は概ね０．０５（ｍ3／トン）程度と小さい値である。例えば４０トンの廃プラスチックをそのまま貯留設備に搬入し、１ｍの高さに均一に貯留する場合、８００ｍ2（例えば２０ｍ×４０ｍ）の貯留面積が必要になる。圧縮の目安としては、０．１５（ｍ3／トン）程度の嵩比重となるまで圧縮する簡易圧縮とする。圧縮率は適宜変更可能であることは言うまでもない。廃プラスチックを圧縮することにより、受入れる貯留設備のスペースは従来の約１／３の面積まで減少できる。
【００３３】
一方、びん，缶は、資源化拠点１の所定の受け入れ設備に設定されている保管容器に収納するか、あるいは収集車による収集時に保管容器に収納し、受入れた後、直ちに貯留工程４に移送し貯留する。
【００３４】
この貯留工程４は、受入れた保管容器を搬送装置で搬送し、所定のエリアに区分され、かつ、高さ方向に複数の棚を連なる立体式貯留設備内の指定棚に貯留する。なお、この立体式貯留設備は、予めびん，缶との貯留エリアと廃プラスチックの貯留エリアに分けられているので、該当する棚に必要な期間貯留する。
【００３５】
立体式貯留設備内に貯留した後、コントローラからの指示に従って搬送装置が搬送し、その指示内容に従って、立体式貯留設備の棚から保管容器を取出し、選別工程５に移される。この選別工程５は、びん，缶用の選別工程と廃プラスチック用選別工程とに分けられ、それぞれの廃棄物の資源化の要求に応じて選別する。
【００３６】
びん，缶用の選別工程は、選別搬送ラインの上流側から下流側にそって例えばスチール缶を取出す磁気選別装置、この選別装置による選別後に残ったびん，アルミ缶のうち、比較的軽いアルミ缶を選別する風力選別装置、この風力選別装置の選別後に残ったびんについてサイズ分けするサイズ分け選別装置、サイズ分けされたびんに対し光を利用して色分けする色分け選別装置などを設け、順次びん，缶の種類分けを実施し、選別処理する。
【００３７】
一方、廃プラスチックは、破袋機および選別装置に供給する。破袋機では、供給される廃プラスチックの入っている包装用ごみ袋を破って廃プラスチックだけをバラバラに落とす処理を行った後、選別装置において固体系プラスチックとフィルム系プラスチックとに選別される。なお、圧縮により嵩比重が増大するために、破袋機及び選別装置へ供給する廃プラスチックの量も圧縮しないときよりも多量となる。
【００３８】
選別装置としては、揺動式選別装置や風力選別装置が用いられる。揺動式選別装置は、所定角度の傾斜で配置された揺動自在のプレートを備えたものであって、揺動するプレート上の廃プラスチックをその反発力の差により固体系プラスチックとフィルム系プラスチックとに分別する装置である。更に、プレートに篩穴を設けた装置によれば、篩穴による篩い分け効果により、小径のプラスチック異物も分別される。選別された固体系プラスチックからＰＥＴボトルのみを更に分離してもよい。
【００３９】
風力選別装置は、容器（塔）内に廃プラスチックを供給し、容器の下方から上方に向って空気流を噴射して軽量物側のフィルム系プラスチックと重量物側の固体系プラスチックとに分離する装置である。
【００４０】
以上のようにして選別工程５により分離された廃プラスチックは、圧縮梱包工程６で圧縮梱包される。一方、選別されたびん，缶は、梱包工程７により何らかの梱包を施した後、梱包品貯留工程８に搬送され、貯留される。この貯留工程８は、所要とする期間貯留するものであって、所定のエリアに区分され、かつ、高さ方向に複数の棚を連なる立体式貯留設備が設置され、当該設備の指定棚に貯留する。必要に応じて梱包後に直ちに搬送車で目的別の再資源化工場に搬送する場合もある。
【００４１】
従って、以上のような廃棄物の資源化方法によれば、圧縮工程と貯留工程の間、貯留工程と選別工程の間は、圧縮された廃プラスチックを貯留工程に搬送し、また貯留されている廃棄物を選別工程に搬送するが、例えば貯留工程となる貯留設備を高さ方向に連なるように構成し、圧縮された廃プラスチックを貯留設備の高さ方向に貯留すれば、少ない床面積で多量の廃プラスチックが貯留可能となる。このことは、貯留設備に搬入する前に圧縮して嵩比重を増加させることにより、従来と同等の貯留設備によって従来よりも多量の廃プラスチックを貯留することができる。また、破袋機や選別装置の処理設備は、廃プラスチックの受入量が限られているが、これらに供給前に圧縮して嵩比重を大きくすれば、従来よりも多くの量の廃プラスチックを供給でき、ひいては処理量の増加、またベルトコンベア等の搬送装置による搬送量も増加し、作業能率の向上にも貢献する。
【００４２】
さらに、貯留工程となる貯留部を高さ方向に連なるように構成し、圧縮された廃プラスチックを貯留設備の高さ方向に搬送しながら貯留すれば、貯留床面積の縮小化、ひいては少ない床面積で多量の廃プラスチックを貯留できる。
【００４３】
さらに、１ヶ所の拠点で各種類の廃棄物を受け付け、貯留・選別を行うので、多種類の廃棄物を集中的に資源管理でき、廃棄物全体に対する作業性が良くなり、資源化のための稼働率を向上できる。
【００４４】
なお、上記実施の形態は、びん，缶とＰＥＴボトルを含む廃プラスチックとに分けて分別収集していることを前提として説明したが、例えばびん，缶，ＰＥＴボトルと当該ＰＥＴボトルを含まない廃プラスチックとに分けて分別収集する場合には、びん，缶，ＰＥＴボトルは貯留工程３で貯留後、選別工程４に移送して選別するが、このとき前述する風力選別装置を用いて、比較的軽いアルミ缶の他、ＰＥＴボトルを抽出分離した後、さらにアルミ缶とＰＥＴボトルとを選別する。また、びん，缶とＰＥＴボトルとその他の廃プラスチックとに分けて分別収集する場合には、その受入れ、貯留，選別等の工程は廃プラスチックと同様の工程で処理する方法で実現できる。
【００４５】
図２は本発明に係わる資源化施設の一実施の形態を示す構成図である。なお、図３は図２に示す施設内に設置する機能別設備のエリア分けを表す図である。
【００４６】
この廃棄物の資源化施設は、収集車で収集され搬入される廃棄物を本発明施設に受入れて搬送するる受入れエリアＡ及び搬送エリアＢに設置される受入れ設備１０と、この受入れ設備１０で受入れた廃棄物のうち、びん，缶とＰＥＴボトルを含む廃プラスチックとに分けて貯留するびん，缶用貯留エリアＣａ及び廃プラ用貯留エリアＣｂからなる貯留エリアＣに設置され、びん，缶と廃プラスチックとを一時的に貯留する立体式貯留設備２０と、この立体式貯留設備２０に貯留されているびん，缶と廃プラスチックとを別々に搬出し、資源として利用可能な状態に選別するびん，缶用選別エリアＤおよび廃プラ用選別エリアＥにそれぞれ設置されるびん，缶用選別設備３０および廃プラ用選別設備４０と、この選別設備４０により選別された資源化された廃棄物を圧縮梱包する梱包エリアＦに設置される梱包機５０と、びん，缶を含む廃プラスチックの梱包された梱包品のうち所要とする梱包品を貯留する梱包品貯留エリアＧに設置される立体式梱包品貯留設備６０とによって構成されている。図３においてＨは出荷エリアである。
【００４７】
なお、各設備の設置エリアは、その一例を図３に示したが、一般的には敷地の形状や施設の形状によって異なるものである。例えば別の例として、図４に示すようにエリア分けすれば、処理の流れに従って設備を順次設置でき、作業性の面で有利と言える。
【００４８】
次に、各設備について説明する。
【００４９】
受入れ設備１０は、例えばびん，缶用受入れエリアと廃プラ用受入れエリアとが隣接して配置され、例えばびん，缶用受入れエリアには例えば２台の収集車１１ａを受入れる受入れバース１２ａが確保され、一方、廃プラ用受入れエリアには例えば３台の収集車１１ｂを受入れる受入れバース１２ｂが確保されている。
【００５０】
この受入れバース１２ａに停車される収集車１１ａの定位置後方には各収集車１１ａに対応してそれぞれ貯留コンテナとなる小型保管容器１３ａが設定され、当該収集車１１ａから下ろされたびん，缶が小型保管容器１３ａ内に収納される。なお、予め収集車１１ａが所定サイズである小型保管容器１３ａ相当の容器にびん，缶を収納した状態で搬入する場合には、受入れバース１２ａには小型保管容器１３ａを設定しなくてもよい。
【００５１】
もう一方に受入れバース１２ｂに停車される収集車１１ｂの定位置後方には各収集車１１ｂに対応してそれぞれ貯留コンテナとなる大型保管容器１３ｂが設定され、各収集車１１ｂから搬入される廃プラスチックの詰め込みが可能な状態になっている。これら保管容器１３ａ，１３ｂは、例えばプラスチック材料を用いて箱状に形成され、保管容器１３ａの大きさは例えば縦・横それぞれ２ｍ、奥行き２ｍサイズのもの、保管容器１３ｂの大きさは例えば縦・横それぞれ２ｍ、奥行き４ｍサイズのもの，つまり奥行きサイズがほぼ２倍大きいものが使用される。これら保管容器１３ａ，１３ｂの収集車対峙面側には、図５に示すごとく上端側枢支形または図示矢印（イ）方向から容器入口ガイド溝にそって閉塞する進退開閉形の蓋体１４ａ，１４ｂが設けられている。なお、容器の反対側にも必要に応じて蓋体を設けるものとする。
【００５２】
この収集車１１ｂと保管容器１３ｂとの間には、再度圧縮を必要とする場合のみ例えばパッカー車などに付設されるスクリュー形圧縮機その他従来公知の圧縮機１５が配置されている。なお、既にラッピングや紐を用いた固縛による圧縮済み廃プラスチックである場合、或いは収集車１１ｂの圧縮で十分である場合、必ずしも圧縮機１５を必要とするものでない。
【００５３】
なお、圧縮機１５が備えられている場合、収集車１１ｂから搬入される廃プラスチックは、圧縮機１５で圧縮しつつ大型保管容器１３ｂに詰め込み、所要量が収容されたとき蓋体１４ｂを閉塞し、搬送用コントローラ（図示せず）に詰込み完了指示を送出する。
【００５４】
また、受入れ設備１０には貯留すべき保管容器１３ａ，１３ｂを搬送し貯留するための搬送装置が設けられている。この搬送装置は、保管容器後部側近傍に位置し、かつ、廃プラスチック詰め込み方向と直交する方向に延在するように床部側に敷設されている例えば２本の下側ガイドレール１６と天井側に設置される例えば１本の上側ガイドレール１７が配置され、これらガイドレール１６，１７間には保管容器１３ａ，１３ｂを搬送し、所要の立体式貯留設備２０の所要とするエリアに貯留する搬送装置本体１８が走行可能に設けられている。
【００５５】
この搬送装置本体１８は、それぞれガイドレール１６，１７間に跨るようように所要の間隔で立設された２つのアーチ状支柱体１８ａと、この２つのアーチ状支柱体１８ａ間に掛け渡され、昇降方向および進退方向（容器貯留方向）に移動可能なテーブル１８ｂと、このアーチ状支柱体１８ａの少なくとも１つの底部に下側ガイドレール１６と回転可能に嵌合され、アーチ状支柱体１８ａに適宜な個所に付設されるモータ等の走行用駆動源（図示せず）によって回転する駆動輪（図示せず）およびアーチ状支柱体１８ａの残りの底部に下側ガイドレール１６と回転可能に嵌合される従動輪（図示せず）と、アーチ状支柱体１８ａの上部に上側ガイドレール１７を両側から挟むように設けられた回転ガイドローラ（図示せず）と、アーチ状支柱体１８ａの適宜な個所に設けられ、テーブル１８ｂを昇降方向および進退方向に移動させる昇降用駆動源（図示せず）および進退用駆動源（図示せず）と、これら駆動源および走行用駆動源の制御指示その他貯留設備全体を統括制御する前述する搬送用コントローラが設けられている。なお、搬送用コントローラは、アーチ状支柱体１８ａではなく、施設内の別の位置に固定設置し、アーチ状支柱体１８ａに設置されたアンテナを介して送受信し、指示内容に応じて必要な駆動源を選択し駆動制御する。
【００５６】
その他、このアーチ状支柱体１８ａには、下側ガイドレール１６の所定位置近傍に設置されるストッパーなどを介して所定位置到達を検知し搬送用コントローラに送出する位置検知センサなどの位置検知手段その他必要な機能が設けられている。なお、位置検知手段は、光学的に検知する場合でも容易に実現できる。
【００５７】
前記立体式貯留設備２０は、搬送装置本体１８が搬送する搬送ラインの受入れ設備１０側と反対側に設置され、所定の間口を有するエリアごとに区分され、かつ、各エリアの上下方向に保管容器１３ａ，１３ｂを貯留するに必要な複数の棚２１を形成した立体式棚構造となっている。つまり、この立体式貯留設備２０は、少なくとも所定の間口を有するエリアごとにアーチ状の棚枠部材２２と、これら複数の棚枠部材２２の上部を連結する横架部材２３と、隣接する各棚枠部材２２に棚を形成するために各エリア内側に突設する棚部材２４とによって構成され、縦・横方向に複数の棚２１が連なった状態に形成されている。
【００５８】
この立体式貯留設備２０は、次工程である選別エリアＤ，Ｅへの搬送距離を考慮し、予め各エリアＤ，Ｅに近い側にびん，缶用貯留エリアＣａと廃プラ用貯留エリアＣｂとが割り当てられ、搬送コントローラの指示のもとに搬送装置本体１８が搬送し貯留するようになっている。
【００５９】
図６は正面から貯留設備２０を見たときの一構成例図であって、棚外枠部材２２に形成された棚２１に対し、テーブル１８ｂ上の保管容器１３ａ，１３ｂを貯留するときの例を示している。
【００６０】
前記搬送用コントローラから棚指定のもとに容器搬出指示を受けたとき、搬送装置本体１８は該当棚２１から保管容器１３ａ，１３ｂを取り出し、びん，缶用選別設備３０または廃プラ用選別設備４０に搬送する。
【００６１】
このびん，缶用選別設備３０は、搬送装置本体１８のテーブル１８ｂから渡されるびん・缶用の小型保管容器１３ａを受け取って開蓋後に当該保管容器１３ａを傾斜させることによりびん，缶を出力する受け台３１と、この受け台３１から受け取ったびん，缶を所要の速度で搬送する第１の選別用搬送装置３２と、この選別用搬送装置３２から流れてくる例えばスチール缶を吸着し所要の方向に搬出し離脱させる磁気選別装置３３と、この磁気選別装置３３による選別後のびん，缶から軽量物であるアルミ缶等を取出す風力選別装置３４と、この風力選別装置３４で選別された軽量物の中に例えば複数種類の異なる廃棄物，例えばアルミ缶やＰＥＴボトルのごとき廃棄物が存在する場合にさらに反射光などを利用して選別する選別装置３５と、風力選別装置３４による選別後のびんを篩にかけて寸法分けするサイズ分け選別装置３６と、サイズ分けされた各種類のびんについてそれぞれ光などを利用して色分け選別する色分け選別装置３７，３７，…とによって構成されている。なお、これら選別装置３３〜３７は予め所定の高さに設定しておけば、選別後にそのまま搬送用の容器に入れて梱包可能となる。また、廃棄物の種類によって選別装置の追加・除去等の変更は当然あり得るものである。
【００６２】
一方、廃プラ用選別設備４０は、搬送装置本体１８から渡される大型保管容器１３ｂを受け取って所定方向に搬送する第２の選別用搬送装置４１、包装用ごみ袋を破る破袋機４２および選別装置４３等で構成される。つまり、搬送装置本体１８は、貯留設備２０から大型保管容器１３ｂを取出し、図７に示す図示矢印（ロ）方向に搬送し、図示右端の定位置で停止したとき、昇降用駆動源の動作によってテーブル１８ｂを所定高さ位置に設定した後、進退用駆動源の動作によって当該テーブル図示矢印（ハ）方向，つまり前方に押し出すように保管容器１３ｂを移動し、このテーブル１８ｂより多少低めに設定される図示矢印（二）方向に移動する第２の選別用搬送装置４１に移し替える。この選別用搬送装置４１は、保管容器１３ｂを包装用ごみ袋を破る破袋機４２に導く役割をもったものであり、保管容器１３ｂが所定位置に到達したとき、蓋体１４ｂが開放され、望ましくは所定位置停止後適当な傾斜角度で傾斜させるなどにより、保管容器１３ｂ内の廃プラスチックを破袋機４２に供給する構成となっている。
【００６３】
この破袋機４２は、図８に示すよう選別用搬送装置４１の下流端のほぼ真下に位置し、表面上に突き出し刃４２ａを突出する回転体４２ｂと、この回転体４２ｂの表面から所定の間隙を有して回転方向に伸び、かつ、回転軸方向に適宜な間隔で配置し、廃プラスチックを落下するスリットを形成するスリット形成体４２ｃとにより構成され、搬送装置４１から供給される廃プラスチックが回転体４２ｂとスリット形成体４２ｃとの間に入ってきたとき、突き出し刃４２ａでごみ袋を引き千切るように破って内部の廃プラスチックを外に出して落下させる機能をもっている。
【００６４】
なお、図８に示す破袋機４２は、理解を促すために一例として図示したまでであって、この構成に限定されるものではない。また、全くごみ袋無しの廃プラスチックの収集の場合には破袋機４２を必要としないことは言うまでもない。
【００６５】
前記選別装置４３は、破袋機通過後の廃プラスチックを再処理システムないし再資源化工場の再処理に合うように選別するものであって、貯留設備内の占有面積を縮小する意味から破袋機４２のほぼ真下に配置され、例えば図９に示すように縦方向に多段式とした揺動選別装置が使用される。
【００６６】
この多段式揺動選別装置の各段の構成は、所定の円軌跡，例えば図示矢印（ホ）に示すような円運動を行う揺動発生源４３ａと、この揺動発生源４３ａの軸体に遊動可能に枢支され、揺動発生源４３ａの円運動に伴って両端が上下方向に揺動可能に設けられた揺動板４３ｂと、この揺動板４３ｂにより選別された廃プラスチックを所定方向に導くガイド部材４３ｃとで構成されている。
【００６７】
この選別装置は、揺動発生源４３ａの円運動に伴う揺動板４３ｂの揺動作用により、破袋機通過後の廃プラスチックのうち、比較的重い材料，例えばボトル類プラスチックを図示左端である下側に移動させ、比較的軽い材料例えばフイルム類プラスチックを図示右端である上側に移動させつつ選別していく機能をもっており、しかも多段化配列構成とすることにより、省スペースで効率的に選別するものである。
【００６８】
なお、各揺動板４３ｂの中心部近傍に異物除去用の複数の篩孔４３ｄが形成され、各揺動板４３ｂの揺動時に篩孔４３ｄにて廃プラスチック中に含む例えばガラス屑等を篩うことにより選別し、下部ガイド部材４３ｅ−４３ｅ間に導く構成となっている。
【００６９】
また、他の選別装置としては、例えば図１０に示すような風力式選別装置を用いてもよい。搬送体または破袋機４２から供給される廃プラスチックに対し、横方向に形成されている吹込み口４３ｆから所要速度の風量を吹き込み、ガイド部材４３ｇを挟んで吹込み口４３ｆに近い側に比較的重い材料，例えばボトル類プラスチックを降下させ、吹込み口４３ｆに遠い側に比較的軽い材料例えばフイルム類プラスチックを降下させる構成である。
【００７０】
さらに、以上のように選別装置４３を用いてボトル類プラスチックとフイルム類プラスチックとを選別し、図２に示すようにボトル類を含む高重量系プラスチック搬送ルート４３ｈと軽重量系プラスチックであるフイルム類プラスチック搬送ルート４３ｉとに分け、所要の場所まで搬送し、人手による選別作業により、最終的にＰＥＴボトルプラスチックとＰＥＴボトル以外のボトルを含むフイルム系プラスチックに選別し、それぞれ対応する圧縮梱包工程６に設置される梱包機５０に導く構成となっている。
【００７１】
この梱包機５０は、一般的に使用されている梱包機，つまり圧縮および固縛可能なＰＥＴボトル梱包機その他のプラスチック梱包機が用いられる。
【００７２】
前記梱包品貯留設備６０は、前述する貯留設備２０と同様に立体式棚構造を有し、梱包機５０によって梱包された梱包品を搬送する選別設備４０の下側に設けられるベルトコンベアまたは梱包品を吊り上げて所定位置間で搬送するクレーン等の梱包品搬送装置が設けられ、このベルトコンベアまたはクレーンから所定位置停止の搬送装置本体１８のテーブル１８ｂに移し替え、梱包品貯留設備６０の指定棚に一時的に貯留する載置する構成となっている。
【００７３】
次に、以上のような廃棄物の資源化施設の動作について説明する。
【００７４】
先ず、初期状態において、搬送用コントローラは、立体式貯留設備２０を構成する各棚２１ごとに設置される例えば光学系の容器有無確認手段からの容器有無情報を取り込んでいるので、何れの棚２１に保管容器１３ａ，１３ｂが存在するか否かを把握している。また、搬送用コントローラは、例えばシーケンスプログラムなどにより、何れの順番で各棚２１に保管容器１３ａ，１３ｂを貯留されているか、何れの順番で貯留された保管容器１３ａ，１３ｂを搬出するか等の運転スケジュールのもとに運用する。
【００７５】
以上の状態において、廃プラスチックを収集した収集車１１ａ，１１ｂが受入れ設備１０の所定位置に入ってくると、保管容器１３ａ，１３ｂが開蓋状態で待機しており、例えば圧縮機１５が設置されている場合には、収集車１１ｂから搬入される廃プラスチックが圧縮機１５により圧縮されながら保管容器１３ｂに詰め込まれていく。そして、保管容器１３ａ，１３ｂに所要量のびん，缶や廃プラスチックが収容されたとき蓋体１４ａ，１４ｂを閉塞し、搬送用コントローラに詰込み完了指示を送出する。
【００７６】
ここで、搬送用コントローラは、搬送装置本体１８に対し、何れの受入れ部分から予め定める順序に基づき立体式貯留設備２０の何れの棚２１に貯留すべきかの指示データを与える。この搬送装置本体１８は、走行用駆動源の動作のもとにガイドレール１６，１７にそって走行し、受入れ設備１０の受入れ部分に来たとき、その受入れ部分に設置されるストッパーなどを介して所定位置到達を検知し搬送用コントローラに送出する。ここで、搬送用コントローラは、昇降用駆動源に指示を出し、テーブル１８ｂを所定高さ位置に設定した後、貯留方向進退用駆動源に指示を出し、テーブル１８ｂを前進させて保管容器１３ａ，１３ｂの下側から持ち上げるようにすくい取って所定位置に後退させる。
【００７７】
しかる後、搬送装置本体１８は、走行用駆動源の動作のもとにガイドレール１６，１７にそって所要の棚位置まで走行して停止する。引き続き、昇降用駆動源の動作のもとに、テーブル１８ｂを該当棚２１の高さ位置に設定し、貯留方向進退用駆動源の動作のもとにびん，缶用貯留エリアまたは廃プラ用貯留エリアの指定棚２１に保存容器１３ａ，１３ｂを貯留する（図６参照）。この場合、テーブル１８ｂは、棚位置よりも多少高目の状態で棚２１に収納し、所定位置まで収納したときに多少下げることにより、該当棚２１に保管容器１３ａまたは１３ｂを貯留する。
【００７８】
その後、搬送用コントローラからある棚２１の保管容器１３ａ，１３ｂを取り出す旨の指示を受けると、搬送装置本体１８は、その該当棚２１に走行し、前述と同様に昇降用駆動および貯留方向進退用駆動源の動作のもとに当該棚２１から保管容器１３ａ，１３ｂをすくい上げるように持ち上げて所定位置まで後退し、しかる後、びん，缶等の保管容器１３ａであれば、びん，缶用選別エリア３０ａ側に搬送し、廃プラスチック等の保管容器１３ｂであれば、図７に示すごとく図示矢印（ロ）方向に搬送し、予め定める定位置で停止する。そして、昇降用駆動源の動作によってテーブル１８ｂを所定高さ位置に設定した後、テーブル１８ｂ上の保管容器１３ａを受け台３１または第２の選別用搬送装置４１に載せる。
【００７９】
搬送装置本体１８のテーブル１８ｂからびん・缶用の小型保管容器１３ａを受け取った受け台３１は、保管容器１３ａの開蓋後に当該保管容器１３ａを傾斜させて第１の選別用搬送装置３２上に落とすと、当該選別用搬送装置３２の上流側に配置される磁気選別装置３３により例えばスチール缶を吸着し所要の方向に搬出して所要の搬送用容器などに収納し、引き続き、下流側に設置される風力選別装置３４によってびん，缶等の中から軽量物であるアルミ缶等を搬送経路の側方に吹き出し、所要の搬送用容器に収納する。
【００８０】
そして、以上のようにして缶を分離した後、残りのびんをサイズ分け選別装置３６に導き、ここで篩にかけてびんのサイズ分けを実施する。サイズ分けされたびんはそれぞれ色分け選別装置３７，３７に導かれ、びんの反射光に基づいて色分けをしながら所要の容器に収納する。
【００８１】
一方、搬送装置本体１８のテーブル１８ｂからびん・缶用の大型保管容器１３ｂを受け取った第２の選別用搬送装置４１は、受け取った保管容器１３ｂを包装用ごみ袋を破る破袋機４２まで搬送し、保管容器１３ｂ内の廃プラスチックを破袋機４２に供給する。
【００８２】
この破袋機４２は、選別用搬送装置４１の下流端から落ちてくる廃プラスチックを回転体４２ｂとスリット形成体４２ｃとの間に取り込み、回転体４２ｂに突出する突き出し刃４２ａでごみ袋を引き千切るように破り、隣接するスリット形成体４２ｃの間からごみ袋やごみ袋以外の廃プラスチックを落としていき、多段式揺動選別装置４３に導く。
【００８３】
この多段式揺動選別装置４３では、図９に示すように揺動発生源４３ａの円運動に伴う揺動板４３ｂの揺動作用により、破袋機通過後の廃プラスチックのうち、比較的重いボトル類プラスチックを図示左端である下側に移動させ、比較的軽いフイルム類プラスチックを図示右端である上側に移動させつつ選別する。そして、ここで選別された廃プラスチックは、ボトル類を含む高重量系プラスチック搬送ルート４３ｈと軽重量系プラスチックであるフイルム類プラスチック搬送ルート４３ｉとに分け、所要の場所まで搬送する。ここで、高重量系プラスチック搬送ルート４３ｈで搬送される廃プラスチックには、ボトル類の他、固形プラスチック、プラスチック以外のものも含むので、人手による選別作業により、プラスチック異物（例えばプラスチック以外のもの、金属材料、おもちゃ、鞄等）を除外する一方、残ったボトル類プラスチックの中にもＰＥＴボトルプラスチックとＰＥＴボトル以外のボトルとがあるので、手選別或いは画像認識その他の自動選別手段により選別し、ＰＥＴボトル以外のボトル類その他必要なプラスチックをフイルム系プラスチック搬送ルート４３ｉに合流させ、ＰＥＴボトル系とフイルム系に分けてそれぞれ対応する梱包機５０に搬送する。
【００８４】
これら梱包機では、それぞれのルート４３ｈ，４３ｉから選別搬送されてくる廃プラスチックを四方から圧縮し、紐等で固縛することにより梱包し、梱包品を生成する。この梱包品の一部または全部は、ベルトコンベアまたはクレーンにより運搬し、所定位置停止の搬送装置本体１８のテーブル１８ｂに移し替え、梱包品貯留設備６０の指定棚に一時的に貯留する。
【００８５】
従って、以上のような実施の形態によれば、搬送ラインに沿って所定のエリアごとに区分され、かつ、各エリアの高さ方向に複数段の棚２１，…を形成した立体式貯留設備２０を設け、しかも立体式貯留設備２０は予めびん，缶用貯留エリアと廃プラ用貯留エリアに分けたことにより、資源化可能な廃棄物の殆どを１つの施設で受入れて集中的に貯留・選別等の管理を実施でき、各エリアの高さ方向に複数段の棚２１，…を形成し、高さ方向に順次積み上げ方式で貯留するので、従来に比較し少ない占有スペースで多量の廃棄物を貯留できる。
【００８６】
また、廃プラスチックの貯留に際し、保管容器１３ｂの手前に圧縮機１５を配置し、収集車１１ｂから搬入された廃プラスチックを圧縮機１５で圧縮し、保管容器１３ｂに詰込むようにしたので、立体式貯留設備２０による貯留を含めて、従来よりも格段に多量の廃プラスチックを貯留できる。
【００８７】
因みに、従来の貯留設備では、収集車で収集した廃プラスチックを貯留ヤードに広げた状態で貯留することから、廃プラスチックは１ｍ３当り０．０５トンしか貯留できない。その結果、例えば４０トンの廃プラスチックを搬入したとき、１ｍ高さに均一に貯留したとしても、８００ｍ２（例えば２０ｍ×４０ｍ）の床貯留面積を必要とする。これに対し、本発明による貯留設備では、保管容器１３ｂの手前に簡易な圧縮機１５を配置し、保存容器１３ｂに圧縮しながら詰込むので、１ｍ３当り０．１５トン程度貯留でき、その後、立体式貯留設備２０に貯留するので、図１１に示すように従来の受入れ貯留ヤード（へ）に対し、図示点線矢印のごとくほぼ３分の１の面積の受入れ貯留ヤード（ト）に縮小させることができる。しかも、保管容器１３ｂに廃プラスチックを詰込んで棚式に整理するので、衛生面ないし環境面からも優れたものとなる。
【００８８】
また、びん，缶用貯留エリアと廃プラ用貯留エリアはそれぞれ次のびん，缶用選別エリア３０ａ、廃プラ用選別エリア４０ａに近い方に設けたことにより、搬送装置本体１８によって保管容器１３ａ，１３ｂを短い距離でスムーズに搬送できる。
【００８９】
さらに、この施設には、びん，缶用選別設備３０と廃プラ用選別設備４０を備えたことにより、自治体で分別収集されるかなりの廃棄物を資源化でき、しかも集中的に集めてた種類の資源化を図ることにより、作業能率の向上および稼働率を高めることができる。
【００９０】
さらに、びん，缶用選別設備３０では、びん，缶に関し、一連の搬送時に材料別，サイズ別，色別等に分けて選別することから、非常に効率的に選別でき、必要な作業を必要とせずに資源化工場でそのまま資源化できる。
【００９１】
さらに、破袋機４２および選別装置４３を縦方向に配置する一方、この選別装置４３として縦方向に多段配列の多段式揺動選別装置を設けることにより、少ない床占有面積でごみ袋の破断および廃プラスチックを所要の種類に選別することができる。
【００９２】
さらに、選別・梱包された梱包品は、その全部または一部を梱包品貯留設備６０に貯留し、必要なときに、資源化工場に搬送可能にすれば、資源化工場への搬送を計画的に進めることができ、施設から外部への搬送効率を上げることができる。
【００９３】
なお、上記実施の形態では、立体式貯留設備２０として、保管容器１３ａ，１３ｂを貯留するに必要なエリアに区分された固定式の棚２１の縦横配列構成としたが、例えば図１２に示すように、組をなす無終端搬送帯７１に所定の間隔でテーブル７２を取付け、最下位の所定点に到達し、かつ、保管容器なしのとき、チェーン，ベルト等その他前記搬送装置本体１８から保管容器１３ｂをテーブル７２上に貯留し、最上位の所定点に到達したとき、駆動チェーンその他の搬送装置４１に移し替えるようにすれば、保管容器１３ｂを円滑に破袋機４２に搬送できる。
【００９４】
また、図１３に示すように、サイロ式建屋７３内にテーブル７４を可変ピッチとするテーブルリフタ（図示せず）を設け、収集車１１ｂから搬出される廃プラスチック７５を搬入装置（図示せず）により建屋内下位のテーブル７４に押し込み、テーブルリフタの上昇動作により上部方向に移送するに従ってテーブル間ピッチを狭めながら圧縮し、最上位に達したとき、押出し機構７６で搬送装置４１に押出し、破袋機・選別装置モジュール７７に供給する構成である。
【００９５】
なお、本明細書において「圧縮梱包する」というのは、実施形態に示すように保管容器に廃プラスチックを押込み、保管容器を含め廃プラスチックを圧縮梱包状態にしている場合のみならず、圧縮した廃プラスチックをフイルムでラップした状態や圧縮廃プラスチックを紐や番線（針金）で縛った状態等，圧縮廃プラスチックがバラバラにならない状態であることの全てを含むものである。
【００９６】
なお、本願発明は、上記実施の形態に限定されるものでなく、その要旨を逸脱しない範囲で種々変形して実施できる。また、各実施の形態は可能な限り組み合わせて実施することが可能であり、その場合には組み合わせによる効果が得られる。さらに、上記各実施の形態には種々の上位，下位段階の発明が含まれており、開示された複数の構成要素の適宜な組み合わせにより種々の発明が抽出され得る。例えば実施の形態に示される全構成要件から幾つかの構成要件が省略されうることで発明が抽出された場合には、その抽出された発明を実施する場合には省略部分が周知慣用技術で適宜補われるものである。
【００９７】
【発明の効果】
以上説明したように本発明方法によれば、多種類の廃棄物である資源を集中的に管理でき、作業性及び稼働率の向上を図ることができる。
【００９８】
また、本発明に係わる資源化施設においては、多種類の廃棄物を集中的に貯留，選別でき、資源を集中的に管理でき、またびん等の破損を少なくして資源化の効率を高めることができる。
【００９９】
さらに、本発明に係わる資源化施設は、各機能分け設備を最適な状態に配置することにより、作業効率を高めることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a waste recycling method and a resource recovery facility for storing and sorting wastes such as general wastes and industrial wastes by type and efficiently recycling them.
[0002]
[Prior art]
Waste plastic such as general waste and industrial waste contains a lot of waste plastic. After separating and collecting bottles and cans from the waste plastic and removing chlorine-containing plastic, it is effective as a raw material and fuel. Recycling technologies are attracting attention, and are moving toward implementation as described below.
[0003]
The conventional waste recycling method separates and collects solid plastics such as bottles, cans, plastic bottles and plastic solids, and film plastics from general wastes, separates bottles, and steel cans and aluminum cans. Recycling is performed by sorting into cans, removing chlorine-containing plastics from solid plastics by dry separation, and removing chlorine-containing plastics from film plastics by wet separation. (Japanese Patent Laid-Open No. 10-57929).
[0004]
By the way, waste plastic contained in waste, for example, can be reused for other resources such as blast furnace raw material, oil, PET granule raw material, etc. by subjecting it to appropriate recycling treatment such as heat treatment at a recycling plant. Yes, bottles and cans can be reprocessed in the same way. However, waste collected in a collection vehicle such as a packer vehicle can be reused as it is because of factors such as the operation schedule, amount of waste, and the form of reuse of waste plastic. It is difficult to carry out the recycling process immediately after being brought into the recycling plant, and it is necessary to select another storage location and store it before the recycling process. This is the same even in the recycling factory, and it is necessary to temporarily store it in a certain place in the factory before the regeneration process.
[0005]
Therefore, conventionally, as shown in FIG. 14, a sorting base (recycling facility) 101 is installed, and, for example, waste plastic separated and collected is carried into a storage facility 102 in the sorting base 101 and stored, and a bag breaker 103 After being separated, the separation device 104 separates the plastic into a solid plastic and a film plastic and generates them as resources in the next step 105.
[0006]
Further, as a conventional waste plastic resource recovery facility, a treatment facility for temporarily storing waste plastic and then crushing it has been proposed (Japanese Patent Laid-Open No. 11-276925). In addition to a waste plastic storage site (hereinafter referred to as a storage yard) that stores waste plastic collected from the source, this resource recovery facility includes a crusher for hard plastic that crushes waste plastic, and a soft that crushes waste plastic. This facility is equipped with a plastic crusher and a cutting machine that cuts large waste plastic, and efficiently crushes it according to the properties of the waste plastic.
[0007]
By the way, the storage yard is a big problem in the waste recycling method and the recycling facility as described above. This is because even if waste collected by a collection vehicle is received in the storage yard sequentially, the bulk density of waste plastics is small, so it takes up a huge amount of floor space not only for transportation and transportation but also for storage. Unless the area is secured, the storage limit will be reached in a short time. In addition, waste plastic not only has a small amount of input and processing amount, but also has a problem that a considerably large space is required when a waste storage facility or a plastic sorting facility is installed.
[0008]
Therefore, conventionally, a large underground storage facility (pit) 113 for temporarily storing the waste 112 carried in the collection vehicle 111 as shown in FIG. 15 is considered from the necessity of reducing the ground waste storage area. It has been.
[0009]
In such a facility, the club bucket 114 suspended from the hoisting crane facility 116 is used to grab the waste 112 from the large underground storage facility 113 and load it on the ground transportation facility 115 or a vehicle, and a separate sorting facility. It will be carried in and will be sorted out for recycling.
[0010]
[Problems to be solved by the invention]
However, the following problems have been pointed out in the above-described waste recycling methods and recycling facilities.
[0011]
(1) Conventionally, bottles, cans and plastic wastes are separated and collected from waste, and stored separately in separate bases. Further, bottles and cans are selected, bottles are color-coded, and aluminum and steel are classified. Furthermore, since plastic waste is sorted as described above, it is necessary to construct a large number of storage bases and sorting bases in a distributed manner, and there is a problem that waste cannot be centrally managed.
[0012]
(2) Further, as a result of constructing a large number of decentralized storage bases and sorting bases, the construction cost of the entire facility increases.
[0013]
(3) Since storage and sorting are performed at each storage base and each sorting base, the work becomes complicated, and the operation rate for resource reduction decreases.
[0014]
(4) Further, as shown in FIG. 15, when the waste 112 is carried in a collection vehicle 111 such as a packer car without being separated and temporarily stored in the large underground storage facility 113, When collecting, dropping to the large underground storage facility 113, and grabbing the waste 112 by the club bucket 114 suspended from the hoisting crane facility 116, a considerable bottle breaks and the efficiency of resource recycling is significantly reduced. There is.
[0015]
The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a waste recycling method for intensively managing various types of waste to improve workability and operating rate.
[0016]
Another object of the present invention is to provide a waste recycling facility that can store and sort a wide variety of waste, eliminates intensive management of resources and breakage of bottles, etc., and increases the efficiency of recycling. There is to do.
[0017]
Furthermore, another object of the present invention is to provide a waste recycling facility in which each function-divided facility is arranged in an optimal state to improve work efficiency.

[0027]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0028]
FIG. 1 is a process diagram for explaining a recycling method for realizing a waste recycling facility according to the present invention.
[0029]
In general, the collection of waste is different in the form of separate collection according to the rules established by each local government. For example, it is separated into mixed waste of bottles, cans, PET bottles and waste plastic (plastic waste including PET bottles). When collecting, when separating and collecting bottles, cans and PET bottles and waste plastic except PET bottles, when separating and collecting bottles, cans and waste plastics (plastic waste including PET bottles) is there. Accordingly, since the waste plastic is separated into the bottle and the can according to a predetermined flow determined in advance, the resource shown in FIG. On the other hand, the bottles and cans are similarly carried into the recyclable base 1 while maintaining the shape at the time of collection by a collecting vehicle having no compression function.
[0030]
Waste plastic is a mixture of solid plastic and film plastic, and solid plastic includes plastic bottles and plastic solids. Most of the plastic bottles are so-called PET bottles made from PET. Examples of the plastic solid material include hard plastic products such as a plastic case in addition to other bottles. On the other hand, film-type plastics include film-type plastics such as trash bags for packaging, tray-type plastics, and the like.
[0031]
Therefore, when the wastes as described above are sorted and carried into, for example, bottles, cans and waste plastics including PET bottles, they are received in the receiving step 2 divided into areas. This acceptance process 2 is preferably set in an adjacent area in order to effectively use the space.
[0032]
Of the waste received in the receiving step 2, the waste plastic is compressed at a compression rate required in the compression step 3 provided with a compression device, packed in a storage container, and transferred to the storage step 4. The bulk specific gravity of waste plastic is approximately 0.05 (mThree/ Ton) and a small value. For example, when 40 tons of waste plastic is carried directly into a storage facility and stored uniformly at a height of 1 m, 800 m2A storage area (for example, 20 m × 40 m) is required. As a standard of compression, 0.15 (mThreeIt is set as simple compression which compresses until it becomes bulk specific gravity of about / ton). It goes without saying that the compression rate can be changed as appropriate. By compressing the waste plastic, the space of the receiving storage facility can be reduced to about 1/3 of the conventional area.
[0033]
On the other hand, the bottles and cans are stored in a storage container set in a predetermined receiving facility of the resource recycling base 1, or stored in a storage container when collected by a collection vehicle, and immediately transferred to the storage process 4 after being received. And store.
[0034]
In this storage step 4, the received storage container is transported by a transport device, and is stored in a designated shelf in a three-dimensional storage facility that is divided into predetermined areas and that has a plurality of shelves connected in the height direction. In addition, since this three-dimensional storage facility is divided into a storage area for bottles and cans and a storage area for waste plastic in advance, it is stored in the corresponding shelf for a necessary period.
[0035]
After storing in the three-dimensional storage facility, the transport device transports in accordance with an instruction from the controller, takes out the storage container from the shelf of the three-dimensional storage facility, and moves to the sorting step 5 in accordance with the content of the instruction. This sorting process 5 is divided into a sorting process for bottles and cans, and a sorting process for waste plastics, and sorting is performed according to the demand for recycling of each waste.
[0036]
The sorting process for bottles and cans is a relatively light aluminum can out of a magnetic sorting device that takes out, for example, steel cans from the upstream side to the downstream side of the sorting transport line, bottles remaining after sorting by this sorting device, and aluminum cans. A wind sorting device that sorts bottles, a size sorting device that sorts the remaining bottles after sorting by this wind sorting device, a color sorting device that uses light to color the sorted bottles, etc. Sort cans and sort them.
[0037]
On the other hand, the waste plastic is supplied to a bag breaker and a sorting device. In the bag-breaking machine, after the packaging waste bag containing the waste plastic to be supplied is broken and only the waste plastic is dropped apart, it is sorted into a solid plastic and a film plastic in a sorting device. In addition, since bulk specific gravity increases by compression, the quantity of the waste plastic supplied to a bag breaker and a sorter also becomes larger than when not compressing.
[0038]
As the sorting device, an oscillating sorter or a wind sorter is used. The oscillating type sorting apparatus has a oscillating plate arranged at a predetermined angle of inclination, and the waste plastic on the oscillating plate is converted into a solid plastic and a film plastic by the difference in the repulsive force. It is a device that sorts into Furthermore, according to the apparatus which provided the sieving hole in the plate, the plastic foreign material having a small diameter is also separated by the sieving effect by the sieving hole. Only the PET bottle may be further separated from the selected solid plastic.
[0039]
The wind power sorter supplies waste plastic into a container (tower) and injects an air flow upward from the bottom of the container to separate it into a light plastic film plastic and a heavy plastic plastic. Device.
[0040]
The waste plastic separated in the sorting step 5 as described above is compressed and packed in the compression packing step 6. On the other hand, the sorted bottles and cans are subjected to some packing in the packing process 7 and then transferred to the packaged goods storage process 8 where they are stored. This storage process 8 is to store for a required period, and is divided into predetermined areas, and a three-dimensional storage facility that is connected to a plurality of shelves in the height direction is installed and stored in a designated shelf of the facility. To do. If necessary, it may be transported immediately after packing to a recycling plant for different purposes by a transport vehicle.
[0041]
Therefore, according to the waste recycling method as described above, the compressed waste plastic is transported to and stored in the storage process between the compression process and the storage process and between the storage process and the sorting process. Waste is transported to the sorting process. For example, if the storage facility that serves as the storage process is configured to be connected in the height direction and the compressed waste plastic is stored in the height direction of the storage facility, a large amount of floor space is required. Of waste plastic can be stored. This means that by compressing and increasing the bulk specific gravity before carrying into the storage facility, a larger amount of waste plastic can be stored by the storage facility equivalent to the conventional one. In addition, the processing equipment of bag-breaking machines and sorting equipment has a limited amount of plastic waste. However, if the bulk specific gravity is increased by compressing the plastic before supply, a larger amount of waste plastic can be obtained. As a result, the amount of processing can be increased, and the amount of transport by a transport device such as a belt conveyor can be increased, which contributes to the improvement of work efficiency.
[0042]
Furthermore, if the storage part that is the storage process is configured to be continuous in the height direction and the compressed waste plastic is stored while being transported in the height direction of the storage facility, the storage floor area is reduced, and consequently the floor area is small Can store a large amount of waste plastic.
[0043]
In addition, each type of waste is received, stored and sorted at a single location, so that multiple types of waste can be centrally managed, improving the workability of the entire waste, and improving resource efficiency. The operating rate can be improved.
[0044]
The above embodiment has been described on the premise that the bottles, cans, and waste plastics including PET bottles are separately collected. For example, the bottles, cans, PET bottles and wastes not including the PET bottles are described. In the case of separate collection for plastic, bottles, cans, and PET bottles are stored in the storage process 3 and then transferred to the selection process 4 to be sorted. After extracting and separating the PET bottle in addition to the light aluminum can, the aluminum can and the PET bottle are further sorted. In the case of separating and collecting bottles, cans, PET bottles, and other waste plastics, the process of receiving, storing, sorting, etc. can be realized by a method of processing in the same process as waste plastics.
[0045]

The position detecting means can be easily realized even when optically detecting.
[0057]
The three-dimensional storage facility 20 is installed on the side opposite to the receiving facility 10 side of the transport line transported by the transport device body 18, is divided into areas having a predetermined frontage, and storage containers are vertically arranged in each area. It has a three-dimensional shelf structure in which a plurality of shelves 21 necessary for storing 13a and 13b are formed. That is, the three-dimensional storage facility 20 includes an arch-shaped shelf frame member 22 for each area having at least a predetermined opening, a horizontal member 23 that connects the upper portions of the plurality of shelf frame members 22, and each adjacent shelf. In order to form a shelf on the frame member 22, the shelf member 24 protrudes from the inside of each area, and a plurality of shelves 21 are connected in the vertical and horizontal directions.
[0058]
This three-dimensional storage facility 20 takes into consideration the transport distance to the sorting areas D and E, which are the next process, in advance on the side close to each area D and E, the bottle storage area Ca and the waste plastic storage area Cb. Is assigned, and the transport device body 18 is transported and stored under the instruction of the transport controller.
[0059]
FIG. 6 is a diagram illustrating a configuration example when the storage facility 20 is viewed from the front, in which the storage containers 13a and 13b on the table 18b are stored in the shelf 21 formed on the shelf outer frame member 22. Is shown.
[0060]
When receiving a container carry-out instruction under the shelf designation from the transport controller, the transport device body 18 takes out the storage containers 13a and 13b from the corresponding shelf 21 and sorts the bottle / can sorting equipment 30 or the waste plastic sorting equipment 40. Transport to.
[0061]
The bottle / can sorting facility 30 receives the bottle / can small storage container 13a delivered from the table 18b of the transport device body 18, and outputs the bottle / can by tilting the storage container 13a after the lid is opened. A cradle 31, a bottle received from the cradle 31, a first sorting transport device 32 that transports cans at a required speed, and a steel can flowing from the sorting transport device 32, for example, is adsorbed. A magnetic sorting device 33 for carrying out and removing in a direction, a wind sorting device 34 for taking out a light weight aluminum can etc. from a bottle and a can after sorting by the magnetic sorting device 33, and a light weight sorted by the wind sorting device 34. A sorting device 35 for further sorting using reflected light, etc., when there are a plurality of different types of waste, such as aluminum cans and PET bottles, A sizing / sorting device 36 for sizing the size of the bottle after sorting by the wind power sorting device 34, and a colour-sorting / sorting device 37, 37,... It is constituted by. In addition, if these sorters 33 to 37 are set at a predetermined height in advance, they can be packed in a container for transport as they are after sorting. In addition, it is of course possible to change the addition / removal of the sorting device depending on the type of waste.
[0062]
On the other hand, the waste plastic sorting facility 40 receives the large storage container 13b delivered from the transport device body 18 and transports it in a predetermined direction, the second sorting transport device 41, the bag breaker 42 for breaking the packaging garbage bags, and the sorting. It is composed of the device 43 and the like. That is, the transport device main body 18 takes out the large storage container 13b from the storage facility 20, transports it in the direction of the arrow (b) shown in FIG. 7, and stops at a fixed position at the right end of the figure. After the table 18b is set at a predetermined height position, the storage container 13b is moved so as to push it forward in the direction of the arrow (c) in the table, that is, forward by the operation of the advance / retreat drive source, and is set slightly lower than the table 18b. To the second sorting transport device 41 that moves in the direction of the indicated arrow (2). The sorting transport device 41 has a role of guiding the storage container 13b to a bag breaker 42 that breaks the garbage bag for packaging. When the storage container 13b reaches a predetermined position, the lid 14b is opened, Preferably, the waste plastic in the storage container 13b is supplied to the bag breaker 42 by, for example, tilting at an appropriate tilt angle after stopping at a predetermined position.
[0063]
As shown in FIG. 8, the bag-breaking machine 42 is located almost directly below the downstream end of the sorting transport device 41, and has a rotating body 42b that protrudes on the surface and protrudes a protruding blade 42a, and a predetermined surface from the surface of the rotating body 42b. Waste plastic that is supplied from the transport device 41 and includes a slit forming body 42c that extends in the rotational direction with a gap and is arranged at an appropriate interval in the rotational axis direction to form a slit for dropping the waste plastic. Has entered the space between the rotating body 42b and the slit forming body 42c, it has a function of tearing out the garbage bag with the protruding blade 42a so that the waste plastic inside is pulled out and dropped.
[0064]
Note that the bag-breaking machine 42 shown in FIG. 8 is shown as an example to facilitate understanding, and is not limited to this configuration. Needless to say, the bag breaker 42 is not required in the case of collecting waste plastic without any garbage bags.
[0065]
The sorting device 43 sorts the waste plastic after passing through the bag breaker so as to be suitable for reprocessing of the reprocessing system or the recycling plant, and breaks the bag in order to reduce the occupied area in the storage facility. For example, as shown in FIG. 9, a swing sorting device having a multistage type in the vertical direction is used.
[0066]
The configuration of each stage of the multistage swing sorting apparatus is based on a predetermined circular locus, for example, a swing generation source 43a that performs a circular motion as shown by an arrow (e) in the figure, and a shaft body of the swing generation source 43a. A swing plate 43b pivotally supported so that both ends of the swing generation source 43a can swing up and down in accordance with the circular motion of the swing generation source 43a, and the waste plastic selected by the swing plate 43b in a predetermined direction. It is comprised with the guide member 43c which guides to.
[0067]
This sorting device has a left-hand side of a relatively heavy material, for example, bottle plastic, out of waste plastic after passing through the bag breaker by the swinging action of the swinging plate 43b accompanying the circular motion of the swinging source 43a. It has the function of moving to the lower side and sorting relatively light materials such as film plastics while moving to the upper side, which is the right end of the figure. In addition, the multi-stage arrangement structure enables efficient sorting in a space-saving manner. Is.
[0068]
A plurality of sieve holes 43d for removing foreign substances are formed in the vicinity of the center of each swing plate 43b. When each swing plate 43b swings, for example, glass dust contained in the waste plastic is sieved through the sieve holes 43d. Thus, the structure is selected and guided between the lower guide members 43e-43e.
[0069]
Further, as another sorting device, for example, a wind type sorting device as shown in FIG. 10 may be used. For the waste plastic supplied from the conveying body or bag breaker 42, the air volume at the required speed is blown from the blowing port 43f formed in the lateral direction, and compared with the side closer to the blowing port 43f across the guide member 43g. A heavy material such as bottle plastic is lowered and a relatively light material such as film plastic is lowered on the side far from the blowing port 43f.
[0070]
Further, as described above, the sorter 43 is used to sort the bottle plastic and the film plastic, and as shown in FIG. 2, the heavy plastic transport route 43h including the bottles and the light plastic plastic film. It is divided into the plastic transport route 43i, transported to the required place, and finally sorted into film-based plastic including PET bottle plastic and bottles other than PET bottles by manual sorting, and the corresponding compression packing process 6 is performed. It is the structure which guides to the packing machine 50 installed.
[0071]
As the packing machine 50, a generally used packing machine, that is, a PET bottle packing machine that can be compressed and secured, or other plastic packing machines is used.
[0072]
The packaged goods storage facility 60 has a three-dimensional shelf structure, similar to the storage equipment 20 described above, and is provided on the lower side of the sorting equipment 40 for transporting the packaged goods packed by the packaging machine 50 or the packaged goods. A packaged goods transport device such as a crane that lifts and transports the paper between predetermined positions is provided, transferred from the belt conveyor or the crane to the table 18b of the transport apparatus body 18 stopped at a predetermined position, and placed on a designated shelf of the packaged goods storage facility 60. It is configured to be temporarily stored.
[0073]
Next, the operation of the waste recycling facility as described above will be described.
[0074]
First, in the initial state, the transfer controller takes in the container presence / absence information from, for example, the container presence / absence confirmation unit of the optical system installed for each shelf 21 constituting the three-dimensional storage facility 20. Whether the storage containers 13a and 13b exist. Further, the transfer controller determines, for example, in which order the storage containers 13a and 13b are stored in the respective shelves 21 and in which order the storage containers 13a and 13b are transferred out by a sequence program or the like. Operate according to the operation schedule.
[0075]
In the above state, when the collection vehicles 11a and 11b that collect the waste plastics enter a predetermined position of the receiving facility 10, the storage containers 13a and 13b are on standby with the lid open, for example, the compressor 15 is installed. In this case, the waste plastic carried from the collection vehicle 11b is packed into the storage container 13b while being compressed by the compressor 15. When the required amount of bottles, cans and waste plastic are stored in the storage containers 13a and 13b, the lids 14a and 14b are closed, and a clogging completion instruction is sent to the transport controller.
[0076]
Here, the transfer controller gives to the transfer device main body 18 instruction data indicating which shelf 21 of the three-dimensional storage facility 20 should be stored based on a predetermined order from which receiving portion. The transport device main body 18 travels along the guide rails 16 and 17 under the operation of the travel drive source, and when it reaches the receiving portion of the receiving facility 10, via a stopper or the like installed at the receiving portion. The arrival at a predetermined position is detected and sent to the controller for conveyance. Here, the transfer controller issues an instruction to the raising / lowering drive source, sets the table 18b to a predetermined height position, then issues an instruction to the storage direction advance / retreat drive source, and advances the table 18b to advance the storage container 13a, The scoop is lifted from the lower side of 13b and retracted to a predetermined position.
[0077]
Thereafter, the transport device main body 18 travels to the required shelf position along the guide rails 16 and 17 under the operation of the travel drive source and stops. Subsequently, the table 18b is set at the height position of the corresponding shelf 21 under the operation of the lifting drive source, and the bottle, the can storage area or the waste plastic storage is stored under the operation of the storage direction advance / retreat drive source. Storage containers 13a and 13b are stored in the designated shelf 21 in the area (see FIG. 6). In this case, the table 18b is stored in the shelf 21 in a slightly higher position than the shelf position, and when it is stored to a predetermined position, the table 18b is slightly lowered to store the storage container 13a or 13b in the corresponding shelf 21.
[0078]
Thereafter, when receiving an instruction to take out the storage containers 13a and 13b of the shelf 21 from the transport controller, the transport device body 18 travels to the corresponding shelf 21 and drives for raising and lowering and for moving forward and backward in the storage direction as described above. Under the operation of the drive source, the storage containers 13a and 13b are lifted up from the shelf 21 and retreated to a predetermined position. After that, if the storage container 13a is a bottle or can, the bottle and can sorting area If it is transported to the 30a side and is a storage container 13b of waste plastic or the like, it is transported in the direction of the arrow (b) shown in FIG. 7 and stopped at a predetermined position. Then, after the table 18b is set to a predetermined height position by the operation of the lifting drive source, the storage container 13a on the table 18b is placed on the receiving base 31 or the second sorting transport device 41.
[0079]
The cradle 31 that receives the bottle / can small storage container 13a from the table 18b of the transport apparatus body 18 tilts the storage container 13a on the first sorting transport apparatus 32 after the storage container 13a is opened. When dropped, the magnetic sorting device 33 arranged on the upstream side of the sorting transport device 32 attracts, for example, a steel can and transports it in the required direction and stores it in the required transport container. Then, the wind power sorter 34 blows out a lightweight aluminum can etc. from the bottles, cans, etc. to the side of the conveyance path and stores it in a required conveyance container.
[0080]
Then, after separating the cans as described above, the remaining bottles are guided to the sizing / sorting device 36, where they are sieved to carry out the sizing of the bottles. The size-divided bottles are respectively guided to the color-sorting and sorting devices 37 and 37 and stored in a required container while being color-coded based on the reflected light of the bottle.
[0081]
On the other hand, the second sorting and transporting device 41 that has received the large storage container 13b for bottles and cans from the table 18b of the transporting device body 18 transports the received storage container 13b to the bag breaker 42 that breaks the trash bag for packaging. The waste plastic in the storage container 13b is supplied to the bag breaker 42.
[0082]
The bag breaker 42 takes in the waste plastic falling from the downstream end of the sorting transport device 41 between the rotating body 42b and the slit forming body 42c, and pulls the garbage bag with the protruding blade 42a protruding to the rotating body 42b. The waste plastics other than the garbage bags and the garbage bags are dropped from between the adjacent slit forming bodies 42 c and guided to the multistage swing sorting device 43.
[0083]
In this multistage swing sorting device 43, as shown in FIG. 9, the swinging plate 43b swings along with the circular motion of the swing generating source 43a, so that the waste plastic after passing through the bag breaker is relatively heavy. The bottle plastic is moved to the lower side, which is the left end in the figure, and the relatively light film plastic is moved to the upper side, which is the right end in the figure. The waste plastic selected here is divided into a high-weight plastic transport route 43h including bottles and a film plastic transport route 43i which is a light-weight plastic, and is transported to a required place. Here, the waste plastic transported by the high-weight plastic transport route 43h includes not only bottles but also solid plastics and other than plastics, so that plastic foreign matter (for example, other than plastics, Metal materials, toys, bags, etc.) are excluded, but there are PET bottle plastics and bottles other than PET bottles among the remaining bottle plastics, so they are sorted by hand sorting or image recognition or other automatic sorting means, Bottles other than PET bottles and other necessary plastics are merged into the film plastic transport route 43i, divided into PET bottle systems and film systems, and transported to the corresponding packing machines 50 respectively.
[0084]
In these packing machines, waste plastics sorted and transported from the respective routes 43h and 43i are compressed from four sides and packed by tying them with strings or the like to generate a packaged product. A part or all of the packaged goods is transported by a belt conveyor or a crane, transferred to the table 18b of the transport apparatus body 18 stopped at a predetermined position, and temporarily stored in a designated shelf of the packaged goods storage facility 60.
[0085]
Therefore, according to the embodiment as described above, a three-dimensional storage facility 20 that is divided into predetermined areas along the transport line and that has a plurality of shelves 21 formed in the height direction of each area. In addition, the three-dimensional storage facility 20 is divided into a bottle, a can storage area, and a waste plastic storage area in advance, so that most of the waste that can be recycled can be received and concentrated in one facility. Etc., and a plurality of shelves 21,... Are formed in the height direction of each area and stored in a stacked manner in the height direction, so that a large amount of waste can be collected with less occupied space than in the past. Can be stored.
[0086]
In addition, when storing the waste plastic, the compressor 15 is disposed in front of the storage container 13b, and the waste plastic carried from the collection vehicle 11b is compressed by the compressor 15 and packed into the storage container 13b. A large amount of waste plastic can be stored, including storage by the type storage facility 20, as compared with the conventional case.
[0087]
By the way, in the conventional storage equipment, the waste plastic collected by the collection vehicle is stored in a state where it is expanded in the storage yard.3Only 0.05 tons can be stored. As a result, for example, when 40 tons of waste plastic is carried in, even if it is stored uniformly at a height of 1 m, it is 800 m.2It requires a floor storage area (for example, 20 m × 40 m). On the other hand, in the storage facility according to the present invention, a simple compressor 15 is arranged in front of the storage container 13b, and the storage container 13b is packed while being compressed.3Since it can be stored in about 0.15 tons per unit and then stored in the three-dimensional storage facility 20, as shown in FIG. It can be reduced to the receiving storage yard (g). In addition, since the waste plastic is packed in the storage container 13b and arranged in a shelf type, it is excellent in terms of hygiene or environment.
[0088]
Further, the storage area for the bottle, the can and the storage area for the waste plastic are provided closer to the next bottle, the sorting area for can 30a, and the sorting area 40a for the waste plastic, respectively. 13b can be smoothly transported at a short distance.
[0089]
In addition, this facility is equipped with a sorting facility 30 for bottles and cans and a sorting facility 40 for waste plastics, so that a considerable amount of waste that is separated and collected by local governments can be turned into resources, and moreover, it is a kind that is collected intensively By improving the resource utilization, the work efficiency can be improved and the operation rate can be increased.
[0090]
Furthermore, since the bottle / can sorting facility 30 sorts the bottles / cans by material, size, color, etc. during a series of transports, it can be sorted very efficiently and requires the necessary work. Instead, it can be recycled as it is at a recycling plant.
[0091]
In addition, while the bag breaking machine 42 and the sorting device 43 are arranged in the vertical direction, the sorting device 43 is provided with a multi-stage swing sorting device having a multi-stage arrangement in the vertical direction, so that the garbage bags can be broken and reduced with a small floor area. Waste plastic can be sorted into required types.
[0092]
Furthermore, all or part of the sorted and packed packages are stored in the package storage facility 60 and can be transported to the resource recovery factory when necessary. Therefore, the efficiency of transporting from the facility to the outside can be increased.
[0093]
In the above-described embodiment, the three-dimensional storage facility 20 has a vertical and horizontal arrangement configuration of the fixed shelves 21 divided into areas necessary for storing the storage containers 13a and 13b. For example, as shown in FIG. In addition, when a table 72 is attached to a pair of endless transport belts 71 at a predetermined interval, and reaches the lowest predetermined point, and there is no storage container, a chain, a belt, etc. The storage container 13b can be smoothly conveyed to the bag breaker 42 by storing 13b on the table 72 and transferring it to the drive chain or other conveying device 41 when the uppermost predetermined point is reached.
[0094]
Further, as shown in FIG. 13, a table lifter (not shown) having a table 74 as a variable pitch is provided in the silo-type building 73, and a waste plastic 75 carried out from the collection vehicle 11b is carried in (not shown).
