Description

【０００１】
【発明の属する技術分野】
本発明は、主として、電子写真装置などの、使用済みトナーカートリッジのトナー分離処理方法及びその処理システムに関するものである。
【０００２】
【従来の技術】
使用済みのトナーカートリッジを分解して、残留トナーと、それ以外の構成物とに分離し、その構成物をリサイクルに供する場合、前記構成物には、大なり小なり、トナーが付着、残留してしまうのが実状である。
【０００３】
そこで、従来は、前記構成物を、同材質部品毎に分離した後で、それぞれの部品からトナーを分離する手法が採用されている。また、リサイクルを意図しないで、前記構成物を廃棄物として処理する場合には、トナーが付着したままで、焼却処分しているが、廃棄物の増大という問題が残る。そこで、低コストでのリサイクルが実現されるトナー分離の処理方法が、模索されている。
【０００４】
【発明が解決しようとする課題】
本発明は、上記事情に基づいてなされたもので、構成物表面へのトナー付着状態を検討すると、構成物に内蔵した磁石や構造物表面に発生した静電気による磁気的吸着および物理的付着が主な原因と考察されるので、トナー分離を、その原因解消によって、効果的に、しかも、低コストで実現できる、使用済みトナーカートリッジのトナー分離処理方法及びその処理システムを提供することを目的とする。
【０００５】
【課題を解決するための手段】
このため、本発明のトナー分離処理方法は、トナーが残留する使用済みトナーカートリッジ本体に対して脱磁処理を行う脱磁工程と、脱磁後の前記トナーカートリッジ本体を、界面活性剤溶解液の散布される領域で所要の大きさに破砕する破砕工程と、前記破砕工程で生成された破砕片とトナー並びに破砕粉を含む界面活性剤溶解液とを篩い分けする分離工程と、前記トナー並びに破砕粉を含む界面活性剤溶解液を遠心力で分離する遠心力分離工程と、前記遠心力分離工程で分離された溶液分を、前記破砕工程のための界面活性剤溶解液として回収、再使用する回収・供給工程とからなることを特徴とする。
【０００６】
この場合、本発明の実施の形態として、前記分離工程が、界面活性剤溶解液の散布される領域で行われること、前記回収・供給工程で回収した界面活性剤溶解液を、前記分離工程へも供給すること、前記分離工程で、篩い分け後に搬出される破砕片を、その搬出の終段で、新規の界面活性剤溶解液で洗浄すること、更には、前記分離工程で篩い分けされた界面活性剤溶解液の余剰分を蒸発処理し、トナー、破砕粉などの残滓から分離することは、有効である。
【０００７】
また、本発明のトナー分離処理装置は、トナーが残留する使用済みトナーカートリッジ本体に対して脱磁処理を行う脱磁手段と、脱磁後の前記トナーカートリッジ本体を、界面活性剤溶解液の散布される領域で所要の大きさに破砕する破砕手段と、前記破砕手段で生成された破砕片とトナー並びに破砕粉を含む界面活性剤溶解液とを篩い分けする分離手段と、前記トナー並びに破砕粉を含む界面活性剤溶解液を遠心力で分離する遠心力分離手段と、前記遠心力分離手段で分離された溶液分を、前記破砕手段のための界面活性剤溶解液として回収、再使用する回収・供給手段とからなることを特徴とする。
【０００８】
この場合、本発明の実施の形態として、前記破砕手段が、界面活性剤溶解液を散布するシャワー手段の下側において、前記散布領域に配置されていること、前記分離手段が、界面活性剤溶解液の散布領域に配置された振動コンベアで構成され、該振動コンベアの篩い分けメッシュを介して、破砕片とトナー並びに破砕粉を含む界面活性剤溶解液とを分離する構成になっていること、前記回収・供給手段で回収された界面活性溶解液を、前記分離手段が配置される散布領域に設けたシャワー手段にも供給するように構成されていること、更には、前記分離手段で分離されたトナー並びに破砕粉を含む界面活性剤溶解液の余剰分を蒸発処理し、トナー、破砕粉などの残滓から分離する蒸発・分離手段を具備していることは有効である。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態を、図面を参照して、具体的に説明する。ここで、本発明のトナー分離処理方法を実現するための装置は、図示のように、基本的には、トナーが残留する使用済みトナーカートリッジ本体に対して脱磁処理を行う脱磁手段１と、脱磁後の前記トナーカートリッジ本体を、界面活性剤溶解液の散布される領域２で所要の大きさに破砕する破砕手段３と、破砕手段３で生成された破砕片とトナー並びに破砕粉を含む界面活性剤溶解液とを篩い分けする分離手段４と、前記トナー並びに破砕粉を含む界面活性剤溶解液を遠心力で分離する遠心力分離手段５と、遠心力分離手段５で分離された溶液分（トナーおよび破砕粉を除いた後の回収界面活性剤溶解液）を、破砕手段２のための界面活性剤溶解液として回収、再使用する、例えば、タンク形式の（回収タンク６ａを具備する）回収・供給手段６とからなる。
【００１０】
特に、この実施の形態では、破砕手段３が、界面活性剤溶解液を散布するシャワー手段７の下側において、散布領域２に配置されており、分離手段４が、別の界面活性剤溶解液の散布領域８に配置された水平振動コンベアで構成され、該振動コンベアの篩い分けメッシュ４ａを介して、破砕片とトナー並びに破砕粉を含む界面活性剤溶解液とを分離する構成になっている。
【００１１】
なお、この実施の形態では、回収・供給手段６で回収された界面活性剤溶解液を、分離手段４が配置される散布領域８に設けたシャワー手段９にも供給するように構成されており、更には、分離手段４で分離されたトナー並びに破砕粉を含む界面活性剤溶解液の余剰分を蒸発処理し、トナー、破砕粉などの残滓から分離するする蒸発・分離手段１０が別に装備されている。
【００１２】
この実施の形態において、散布領域２は、破砕手段３に脱磁手段１から供給された使用済みトナーカートリッジを誘導する通路１１の両側にシャワー手段７を位置させた筒状の縦壁面２ａで囲まれたものであり、その下には、筒状の縦壁面８ａで囲まれる散布領域８が位置している。そして、その下には、濾斗状の回収タンク１２が配置されていて、界面活性剤溶解液でトナーカートリッジの破砕片表面から洗い落とされたトナー並びに破砕粉（篩い分け）を含む、回収溶液分が篩い分けメッシュ４ａを介して、収容される。一方、前記振動コンベアの搬送端には、破砕片の取り出し部１３があり、所要の個所（他のリサイクル処理、例えば、材質別の分離処理）へのルートが接続してある。
【００１３】
而して、この装置を用いて、本発明のトナー分離処理を行う場合について、ステップ順に説明する。
１）脱磁工程：使用済みカートリッジは、その構成物の中に、磁石などの内蔵物があり、また、静電気による磁気的なトナー吸着能を除くため、ルート１４を介して、脱磁手段１に供給される。そして、ここを通過する際に、脱磁される。
２）破砕工程：前記カートリッジの主要部分は、一般に硬質合成樹脂であり、これは、例えば、ローラ対で構成される破砕手段２において、破砕されるが、この時、内蔵物である磁石なども分離される。なお、この破砕の際に、細かな破砕粉が若干、発生する。しかも、この破砕された構成物は、シャワー手段７からの界面活性剤溶解液のシャワーを浴び、その表面に付着するトナーを、粉砕粉と共に洗い流す。
３）分離工程：振動コンベア上にもたらされた破砕片と、トナー並びに破砕粉を含む前記界面活性剤溶液とは、篩い分けメッシュ４ａを介して、分離されるが、更には、シャワー手段９を介して供給された界面活性剤溶解液のシャワーが篩い分けメッシュ４ａ上に残留する破砕片の表面を洗い流す。そして、トナー並びに破砕粉を含む前記界面活性剤溶解液は、回収タンク１２に回収され、一方、洗浄された破砕片は、取り出し部１３を介して、所要のリサイクル処理のルートに送られる。
４）遠心分離工程：所謂、遠心分離機などの、遠心分離手段５には、回収タンク１２からトナー並びに破砕粉を含む界面活性剤溶解液が供給され、ここで、遠心分離作用で、トナーや破砕粉を溶液から分離する。
５）回収・供給工程：そして、分離された溶液（再生界面活性剤溶解液）は回収・供給手段６にもたらされる。ここでは、例えば、溶液濃度などの調整を行い、再度、シャワー手段７および９へと界面活性剤溶解液を供給する。
【００１４】
このようにして、本発明のトナー分離処理が実現されるが、特に、この実施の形態では、分離工程において、篩い分けメッシュ４ａにおいて、篩い分けされた破砕片を、振動コンベアからの搬出直前の位置に、清純な新規界面活性剤をシャワー手段９の幾つかからシャワーすることで、確実に洗浄することができる。
【００１５】
また、新規界面活性剤溶解液の量が、このトナー分離処理システムの運転で失う量よりも多い場合、即ち、回収タンク１２に貯留される、回収溶液分（トナー並びに破砕粉を含む界面活性剤溶解液）に余剰分が生じた場合、これを蒸発・分離工程で、システム外に取り出すことができる。このために、上述の蒸発・分離手段１０が用いられる。
【００１６】
なお、この実施の形態では、破砕のための領域２と分離のための領域８とを別の構成としているが、共通のシェルの中に構成しても良い。また、分離された破砕片の再生処理やトナー、破砕粉の分離再生や廃棄処理などを、本発明の処理工程に連続して行うように構成しても良いことは勿論である。
【００１７】
【発明の効果】
本発明は、以上説明したようになり、トナーが残留する使用済みトナーカートリッジ本体に対して脱磁処理を行う脱磁工程と、脱磁後の前記トナーカートリッジ本体を、界面活性剤溶解液の散布される領域で所要の大きさに破砕する破砕工程と、前記破砕工程で生成された破砕片とトナー並びに破砕粉を含む界面活性剤溶解液とを篩い分けする分離工程と、前記トナー並びに破砕粉を含む界面活性剤溶解液を遠心力で分離する遠心力分離工程と、前記遠心力分離工程で分離された溶液分を、前記破砕工程のための界面活性剤溶解液として回収、再使用する回収・供給工程とを行うことで、比較的簡単なシステム構成で、確実にトナー分離ができ、破砕片の形で、トナーカートリッジの構成物を回収することができる。このため、リサイクルのための、その後の破砕片について、材質中心の分離作業を容易にできる利点がある。
