Description

【0001】
【発明の属する技術分野】
本発明は、コンビニエンスストア、スーパー、ホテル等の店舗から排出される生ごみ入り包装容器を収集するごみ収集車に関するものである。
【0002】
【従来の技術】
一般に、コンビニエンスストア、スーパー、ホテル等においては、多種多様の食品を販売しており、販売政策上、賞味期限切れ食品を廃棄処分するようにしている。この賞味期限切れ食品等の生ごみ入り包装容器をそのまま焼却処分した場合には、容器焼却時にダイオキシンが発生して地球環境に悪影響を及ぼすおそれがあり、生ごみ入り包装容器を生ごみと包装容器ごみとに分別して処分した方が好ましい。
【0003】
生ごみ入り包装容器を生ごみと包装容器ごみとに分別するごみ収集車として、例えば特開2000−289805号公報に記載されたものが知られている。このごみ収集車は、回転自在に保持された回転軸と、回転軸に固定された複数の撹拌羽根とを有する包装材破砕装置を備えている、このごみ収集車によれば、投入された生ごみ入り包装容器を撹拌羽根により破砕した後、装置内部に発生させた風により包装容器ごみを生ごみから分離している。
【0004】
【発明が解決しようとする課題】
しかしながら、前記ごみ収集車では、一度に大量の生ごみ入り包装容器を投入すると、生ごみ入り包装容器を生ごみと包装容器ごみとに分離する際の抵抗により、撹拌羽根の回転数が下がり、ごみの分離性能が著しく低下するという問題点があった。
【0005】
本発明は、前記事情に鑑みてなされたものであり、その目的とするところは、一度に大量の生ごみ入り包装容器を投入した場合における撹拌羽根の回転数の低下を防止し、生ごみ入り包装容器を生ごみと包装容器ごみとに的確に分離することのできるごみ収集車を提供することにある。
【0006】
【課題を解決するための手段】
前記目的を達成するため、請求項1記載の発明では、運転席の後方の荷台にごみ収容部2が設けられたごみ収集車1において、前記ごみ収容部は、外部より生ごみ入り包装容器が投入されるごみ投入部3と、前記ごみ投入部より投入された前記生ごみ入り包装容器を受容し前記生ごみ入り包装容器を生ごみと包装容器ごみとに分離するごみ分離箱4と、前記ごみ分離箱の下部と連通し前記ごみ分離箱にて分離された前記生ごみを受容する生ごみ収容箱5と、前記ごみ分離箱の上側と連通し前記ごみ分離箱にて分離された前記包装容器ごみを受容する包装容器ごみ収容箱6とを有し、前記ごみ投入部に、投入された前記生ごみ入り包装容器を破砕する破砕機構7を設け、前記ごみ分離箱の内部に、破砕された前記生ごみ入り包装容器を撹拌し、送出風を発生させて前記包装容器ごみを前記生ごみと分離し、分離された前記生ごみを前記生ごみ収容箱へ送出するとともに、前記送出風により前記包装容器ごみを前記包装容器ごみ収容箱へ送出する撹拌羽根9を備え
前記包装容器ごみ収容箱と前記ごみ投入部の前部上側とを連通する通気管を備え、
前記包装容器ごみ収容箱に、前記ごみ分離箱から送出される前記包装容器ごみを受容する包装容器ごみ用開口が設けられ、
前記通気管の前記ごみ投入部側の開口、前記破砕機構、前記包装容器ごみ用開口の順でこれらが前から後に並べて配置され、
前記ごみ分離箱の内部で前記撹拌羽根により発生する前記送出風が、前記包装容器ごみ収容箱の上部から、前記通気管、前記ごみ投入部及び前記破砕機構を介して前記包装容器ごみ用開口よりも前側から前記ごみ分離箱に帰還するよう構成したことを特徴とする。尚、ここでいう包装容器ごみとは、食品の包装容器ごみの他、爪楊枝、割箸等のごみも含まれるものとする。
【0007】
請求項1記載の発明によれば、ごみ投入部より投入された生ごみ入り包装容器はごみ分離箱にて生ごみと包装容器ごみとに分離された後、生ごみは生ごみ収容箱に、包装容器ごみは包装容器ごみ収容箱にそれぞれ収容される。ここで、ごみ分離箱に導入される前の段階で生ごみ入り包装容器は破砕されており、生ごみ入り包装容器を生ごみと包装容器ごみとに分離する際の撹拌羽根に加わる抵抗は極めて小さい。従って、一度に大量の生ごみ入り包装容器を投入した場合においても撹拌羽根の回転数が低下することはなく、生ごみ入り包装容器を生ごみと包装容器ごみとに的確に分離することができる。
【0009】
また、請求項記載の発明によれば、上記の作用に加え、撹拌羽根により発生した送出風は、ごみ分離箱から包装容器ごみ収容箱を経由し、再びごみ分離箱に帰還する。従って、送出風に含まれる悪臭が車両周囲に拡散することはない。また、送出風はごみ投入部を介してごみ分離箱に帰還するので、生ごみ入り包装容器がごみ投入部からごみ分離箱へ移動し易くなる。
【0010】
請求項記載の発明では、請求項記載のごみ収集車において、前記生ごみ収容箱に受容された前記生ごみを圧縮する生ごみ圧縮手段(例えば、生ごみ圧縮部25等)と、前記包装容器ごみ収容箱に受容された前記包装容器ごみを圧縮する包装容器ごみ圧縮手段(例えば、包装容器ごみ圧縮部26等)とを備えたことを特徴とする。
【0011】
請求項記載の発明によれば、請求項の作用に加え、生ごみ収容箱内の生ごみは生ごみ圧縮手段により圧縮され、包装容器ごみ収容箱内の包装容器ごみは包装容器ごみ圧縮手段により圧縮されるため、生ごみ及び包装容器ごみの収容効率が飛躍的に増大する。従って、生ごみ及び包装容器ごみの積載可能量が増大し、ごみの回収効率の向上を図ることができる。
【0012】
また、請求項記載の発明では、請求項記載のごみ収集車において、前記生ごみ収容箱及び前記包装容器ごみ収容箱は、それぞれ前後に延び後面が開放されたものであって、前記生ごみ収容箱の後面を開閉する生ごみ用扉10と、前記生ごみ収容箱内に前後方向へ移動自在に設けられ、外部へ前記生ごみを排出可能な生ごみ排出部材11と、前記包装容器ごみ収容箱の後面を開閉する包装容器ごみ用扉13と、前記包装容器ごみ収容箱内に前後方向へ移動自在に設けられ、外部へ前記包装容器ごみを排出可能な包装容器ごみ排出部材14とを備え、前記生ごみ圧縮手段を、前記生ごみ用扉が前記生ごみ収容箱の後面を閉塞した状態で、前記生ごみ排出部材が後方に移動して前記生ごみを圧縮する構成とし、前記包装容器ごみ圧縮手段を、前記包装容器ごみ用扉が前記包装容器ごみ収容箱の後面を閉塞した状態で、前記包装容器ごみ排出部材が後方に移動して前記包装容器ごみを圧縮する構成としたことを特徴とする。
【0013】
請求項記載の発明によれば、請求項の作用に加え、生ごみ排出部材は生ごみを外部へ排出する機能と生ごみを圧縮する機能とを併有し、包装容器ごみ排出部材に包装容器ごみを外部へ排出する機能と包装容器ごみを圧縮する機能とを併有する。従って、部品点数を減じて車両コストの低減を図るとともに、構造を簡素化して信頼性を向上することができる。
【0014】
また、請求項記載の発明では、請求項または記載のごみ収集車において、前記生ごみを圧縮する際に、前記生ごみ収容箱から前記ごみ分離箱への前記生ごみの移動を規制する生ごみ規制手段(例えば、生ごみ規制機構16等)を備えたことを特徴とする。
【0015】
請求項記載の発明によれば、請求項またはの作用に加え、生ごみ排出部材に押圧された生ごみがごみ分離箱側へ逆流することはない。従って、生ごみがごみ分離箱側へ逆流してごみ分離箱等を損壊するおそれはない。
【0016】
また、請求項記載の発明では、請求項1乃至の何れか1項記載のごみ収集車において、前記ごみ投入部は前記ごみ収容部の上部に設けられたものであり、前記生ごみ収容箱と前記包装容器ごみ収容箱は左右に並設されたものであって、前記包装容器ごみ収容箱の前端が前記生ごみ収容箱の前端よりも後方になるようにし、前記包装容器ごみ収容箱の前方に、車両側部から前記ごみ収容部の上部へ前記生ごみ入り包装容器を搬送し、前記生ごみ入り包装容器を前記ごみ投入部へ投入する搬送投入機構21を備えたことを特徴とする。
【0017】
請求項記載の発明によれば、請求項1乃至の何れか1項の作用に加え、作業者は、ごみ収容部の上部に設けられたごみ投入部まで、自力で生ごみ入り包装容器を運ぶ必要はなく、搬送投入機構によりごみ投入部に生ごみ入り包装容器を投入することができる。また、包装容器ごみ収容箱の前方に搬送投入機構が備えられるので、車両の車幅方向寸法を大きくすることなく、限られた荷台スペースに搬送投入機構を備えることができる。従って、ごみ投入時における作業者の負担を軽減することができるし、搬送投入機構により車両の車幅方向寸法が大きくなることもない。
【0018】
【発明の実施の形態】
図1乃至図13は本発明の一実施形態を示すもので、図1はごみ収集車の側面図、図2はごみ収集車の背面図である。
【0019】
図1に示すように、このごみ収集車1の運転席後方の荷台には、ごみ収容部2が設けられている。ごみ収容部2はその上部に設けられたごみ投入部3と、ごみ投入部3の下部に接続されたごみ分離箱4と、ごみ分離箱4の下部と連通する生ごみ収容箱5と、ごみ分離箱4の左側部上側と連通する包装容器ごみ収容箱6とを有している。
【0020】
ごみ投入部3は、上部から下部に向かって窄むホッパー状に形成され、上部及び下部が開口されている。ここで、下部開口はごみ分離箱4の天井面に接続されており、上部開口から投入された生ごみ入り包装容器はごみ分離箱4内へと案内される。本実施形態においては、ごみ投入部3は、前部が後下がりに傾斜するとともに、左側部が右下がりに傾斜している。
【0021】
また、ごみ投入部3の下部開口付近には、生ごみ入り包装容器を破砕する破砕機構7が設けられる。図7及び図8に示すように、破砕機構7は、それぞれ前後に延びる左右一対の回転軸7aと、各回転軸7aに軸方向に間隔をおいて装着された複数の破砕具7bとを有しており、左右の回転軸7aの各破砕具7bは互い違いとなるよう配置される。本実施形態においては、各破砕具7bは厚さ寸法及び径寸法が不定な略円盤状であり、その外周は歯状に形成されている。
【0022】
図5及び図6に示すように、ごみ分離箱4は、ごみ投入部3にて破砕された生ごみ入り包装容器を受容し、その内部には略円筒状のドラム8と、ドラム8内に設けられ生ごみ入り包装容器を生ごみと包装容器ごみとに分離する撹拌羽根9とが備えられている。尚、ここでいう包装容器ごみとは、食品の包装容器ごみの他、爪楊枝、割箸等のごみを含むものである。
【0023】
ドラム8は、その下部に形成された複数の篩い孔(図示せず)と、その左側部上側に形成された送出口(図示せず)とを有している。撹拌羽根9は、前後に延びる回転軸9aに径方向外側に延びるよう設けられ、本実施形態においては、計4枚の撹拌羽根9が略90度の間隔で回転軸9aに装着される。回転軸9aが回転すると、破砕された生ごみ入り包装容器が撹拌され、各撹拌羽根9により発生する送出風により、生ごみに比して軽量の包装容器ごみが送出口からドラム8外へと送出される。また、生ごみは各撹拌羽根9によりドラム8の下部に押し付けられ、各篩い孔からドラム8外へと落下する。ここで、ごみ分離箱4の下部のドラム8に対応する部分は開口しており、ドラム8から落下する生ごみは生ごみ収容箱5に受容される。また、ごみ分離箱4の左側部上側の一部は開口しており、送出口から送出される包装容器ごみは包装容器ごみ収容箱6に受容されるようになっている。
【0024】
生ごみ収容箱5は前後に延び後面を開放しており、後面を開閉する生ごみ用扉10を閉塞することで、図11に示すような密閉状態となり、生ごみ用扉10を開放することで、図10に示すような開放状態となる。生ごみ収容箱5の天井面には、ごみ分離箱4に対応して生ごみ用開口5aが形成され、ごみ分離箱4から落下する生ごみが生ごみ収容箱5に受容される。本実施形態においては、ごみ分離箱4は生ごみ収容箱5の前側上方に位置しており、生ごみ用開口5aは天井面の前側に設けられている。
【0025】
また、生ごみ収容箱5内の前端側には、生ごみ収容箱5内を前後方向に移動自在な生ごみ排出部材11と、生ごみ排出部材11を駆動する生ごみ排出駆動部12が配されている。生ごみ排出部材11はその後面が後下がりに傾斜して形成され、生ごみ排出駆動部12の駆動により前後へ移動するようになっている。生ごみ排出駆動部12はシリンダにより前後に伸縮するよう構成され、伸張時に生ごみ排出部材11とともに生ごみを後方へ移動させる。
【0026】
包装容器ごみ収容箱6は前後に延び後面を開放しており、後面を開閉する包装容器ごみ用扉13を閉塞することで、図13に示すような密閉状態となり、包装容器ごみ用扉13を開放することで、図12に示すような開放状態となる。包装容器ごみ収容箱6の右側面には、ごみ分離箱4に対応して包装容器ごみ用開口6aが形成され、ごみ分離箱4から送出される包装容器ごみが包装容器ごみ収容箱6に受容される。本実施形態においては、ごみ分離箱4は包装容器ごみ収容箱6における前側上部の右側方に位置しており、包装容器ごみ用開口6aは右側面の前側上部に設けられている。
【0027】
また、包装容器ごみ収容箱6内の前端側には、包装容器ごみ収容箱6内を前後方向に移動自在な包装容器ごみ排出部材14と、包装容器ごみ排出部材14を駆動する包装容器ごみ排出駆動部15が配されている。包装容器ごみ排出部材14はその後面下部が後下がりに傾斜して形成され、包装容器ごみ排出駆動部15の駆動により前後へ移動するようになっている。包装容器ごみ排出駆動部15はシリンダにより前後に伸縮するよう構成され、伸張時に包装容器ごみ排出部材14とともに包装容器ごみを後方へ移動させる。
【0028】
また、本実施形態においては、図5及び図6に示すように、生ごみ収容部5からごみ分離箱4への生ごみの移動を規制する生ごみ規制機構16が備えられている。生ごみ規制機構16は、生ごみ収容箱5の生ごみ用開口5aを塞ぐよう形成された生ごみ規制板17と、生ごみ規制板17を生ごみ収容箱5の上方左側へ案内する前後一対の案内レール18と、案内レール18に沿って生ごみ規制板17を駆動する規制駆動部19とを有している。
【0029】
生ごみ規制板17は上部に突設された案内軸取付部17aを有し、案内軸取付部17aには案内レール18に嵌合し左右一対の前後に延びる案内軸17bが設けられている。また、生ごみ規制板17は上部の左右一端側に突設された駆動軸取付部17cを有し、駆動軸取付部17cには規制駆動部19に回動自在に連結され前後に延びる駆動軸17dが設けられている。
【0030】
各案内レール18は生ごみ収容箱5の上方を略左右方向に延び、その略中央は左上がりに傾斜して形成されている。即ち、各案内レール18は生ごみ規制板17を略左右方向に案内しており、生ごみ規制板17が右方に位置するときは、図5に示すように生ごみ規制板17により生ごみ用開口5aが閉塞され、この状態から生ごみ規制板17が生ごみ用収容箱5の左側上方に移動すると、図6に示すように生ごみ用開口5aが開放されるようになっている。
【0031】
規制駆動部19は、一端が生ごみ収容箱5の右側上方に回動自在に固定されたシリンダ部19aと、シリンダ部19aの他端から出没する駆動ロッド19bとを有している。駆動ロッド19bの一端側はシリンダ部19a内を移動するとともに、駆動ロッド19bの他端側は生ごみ規制版17の駆動軸17dに回動自在に連結されている。即ち、規制駆動部19は左下がりに傾斜して伸縮自在に構成されており、その収縮時に生ごみ規制板17が右方に位置し、その伸張時に傾斜が緩やかになるとともに生ごみ規制板17が左方に移動する。
【0032】
また、図3及び図4に示すように、包装容器収容箱6とごみ投入部3とを連通する通気管20が備えられている。本実施形態においては、通気管20は包装容器収容箱6の上面前端側と、ごみ投入部3の前部上側とを連通している。通気管20は、包装容器収容箱6の上面前端側から右方に延び、ゴミ投入部3の後方から右側方を経由してゴミ投入部3の前面上部に周りこんでいる。これにより、通気管20が後述する搬送投入機構21と干渉しないようになっている。
【0033】
包装容器ごみ収容箱6の前方には、搬送投入機構21が設けられる。搬送投入機構21は、前後一対の外レール22と、外レール22の車幅方向内側(右側)に配された前後一対の内レール23と、各レール22,23に案内される搬送バケット24とを有している。
【0034】
各外レール22は上下方向に延び、上端及び下端にスプロケットを有し、各スプロケットを巻回するチェーンが設けられている。各チェーンは、図示しないモータにより駆動するようになっている。各内レール23は上下方向に延び、上端が車幅方向内側に屈曲している。
【0035】
搬送バケット24は、各チェーンに連結され上下方向に移動するバケットサポート(図示せず)に軸着されるとともに、各内レール23と嵌合している。搬送バケット24は上部を開口した箱状に形成され、生ごみ入り容器を収納可能となっている。尚、搬送バケット24はバケットサポートに対して着脱自在となっており、非使用時には後側の各レール22,23と包装容器収容箱6との間に配置される。
【0036】
ここで、図3及び図4を参照して搬送投入機構21の動作について説明する。図3に示すように搬送バケット24が車両側部に位置した状態で、前記モータにより各外レール22のチェーンが駆動すると、バケットサポートとともに搬送バケット24が上昇する。ここで、搬送バケット24は上端を右方に屈曲させた各内レール23と嵌合していることから、各内レール23の上端付近まで上昇すると、図4に示すように搬送バケット24は右方に傾倒し、生ごみ入り包装容器はごみ投入部3に自動的に投入されるようになっている。
【0037】
また、ごみ収集車1は、生ごみ及び包装容器ごみの圧縮制御を行う制御部27を有している。図9に示すように、制御部27は、生ごみ用扉10と、生ごみ排出駆動部12と、規制駆動部19とにそれぞれ接続し、制御部27、生ごみ用扉10、生ごみ排出駆動部12及び規制駆動部19で生ごみ圧縮部25をなしている。制御部27は生ごみ収容箱5に生ごみが溜まると、図11に示すように、規制駆動部19を駆動して生ごみ用開口5aを閉塞し、且つ、生ごみ用扉10を閉塞した状態で、生ごみ排出駆動部12を駆動して生ごみ排出部材11を後方に移動する。これにより、生ごみは生ごみ排出部材11と生ごみ用扉10とに狭圧され、生ごみ収容箱5内で生ごみが圧縮される。即ち、生ごみ排出部材11は、生ごみの排出機能と、生ごみの圧縮機能とを併有している。
【0038】
また、図9に示すように、制御部27は、包装容器ごみ用扉13と、包装容器ごみ排出駆動部15とにそれぞれ接続し、制御部27、包装容器ごみ用扉13及び包装容器ごみ排出駆動部15で包装容器ごみ圧縮部26をなしている。制御部27は包装容器ごみ収容箱6に包装容器ごみが溜まると、図13に示すように、包装容器ごみ用扉13を閉塞した状態で、包装容器ごみ排出駆動部15を駆動して包装容器ごみ排出部材14を後方に移動する。これにより、包装容器ごみは包装容器ごみ排出部材14と包装容器ごみ用扉13とに狭圧され、包装容器ごみ収容箱6内で包装容器ごみが圧縮される。即ち、包装容器ごみ排出部材14は、包装容器ごみの排出機能と、包装容器ごみの圧縮機能とを併有している。
【0039】
以上のように構成されたごみ収集車1においては、搬送バケット24からごみ投入部3に投入された生ごみ入り包装容器は、破砕機構7にて破砕された後、自重によりごみ投入部3の下部開口を通じてごみ分離箱4に案内される。そして、ごみ分離箱4にて生ごみと包装容器ごみとに分離された後、生ごみは生ごみ収容箱5に、包装容器ごみは包装容器ごみ収容箱6にそれぞれ収容される。ここで、ごみ分離箱4に導入される前の段階で生ごみ入り包装容器は破砕機構7により破砕されており、生ごみ入り包装容器を生ごみと包装容器ごみとに分離する際の各撹拌羽根9に加わる抵抗は極めて小さいものとなっている。また、ごみ分離箱4における各ごみの分離時に各撹拌羽根9により発生する送出風は、図3及び図4の矢印に示すように、ごみ分離箱4、包装容器ごみ収容箱6、通気管20、ごみ投入部3、ごみ分離箱4の順に循環している。ここで、送出風はごみ投入部3を介してごみ分離箱4に帰還するので、生ごみ入り包装容器がごみ投入部3からごみ分離箱4へ移動し易くなっている。
【0040】
そして、生ごみ収容箱5内に生ごみが溜まると、前述のように、生ごみ圧縮部25により生ごみが圧縮される。このとき、生ごみ規制板17により生ごみのごみ分離箱4への移動が規制され、生ごみ排出部材11に押圧された生ごみがごみ分離箱4側へ逆流することはない。また、包装容器ごみ収容箱6内に包装容器ごみが溜まると、前述のように、包装容器ごみ圧縮部26により包装容器ごみが圧縮される。ここで、生ごみ収容箱5内及び包装容器ごみ収容箱6内の前側に、ごみ分離箱4から送出された生ごみ及び包装容器ごみが受容されるが、各ごみは圧縮されて各収容箱5,6の後側から蓄積されていくので、各ごみが各収容箱5,6の前側に偏って溜まることはない。
【0041】
このように、本実施形態のごみ収集車1によれば、各撹拌羽根9に加わる抵抗が極めて小さいので、一度に大量の生ごみ入り包装容器を投入した場合においても各撹拌羽根9の回転数が低下することはなく、生ごみ入り包装容器を生ごみと包装容器ごみとに的確に分離することができる。さらに、各撹拌羽根9の駆動に要する電力等の駆動コストを低減することができる。
【0042】
また、本実施形態のごみ収集車1によれば、ごみ分離箱4の下方から生ごみを落下させるとともに、生ごみに比して軽量な包装容器ごみをごみ分離箱4の上側から送出するようにしたので、これによっても、生ごみ入り包装容器を生ごみと包装容器ごみとに的確に分離することができる。
【0043】
また、本実施形態のごみ収集車1によれば、各撹拌羽根9により発生した送出風は、ごみ分離箱4から包装容器ごみ収容箱6を経由して再びごみ分離箱4に帰還するようにしたので、送出風に含まれる悪臭が車両周囲に拡散することはない。
【0044】
また、本実施形態のごみ収集車1によれば、生ごみ圧縮部25及び包装容器ごみ圧縮部26により生ごみ及び包装容器ごみを圧縮するようにしたので、各ごみの収容効率が飛躍的に増大する。従って、生ごみ及び包装容器ごみの積載可能量が増大し、ごみの回収効率の向上を図ることができる。
【0045】
また、本実施形態のごみ収集車1によれば、生ごみ収容箱5及び包装容器ごみ収容箱6の前側に、生ごみ及び包装容器ごみが偏って溜まることはなく、効率良く各ごみを収容することができる。
【0046】
また、本実施形態のごみ収集車1によれば、生ごみ排出部材11は生ごみの排出機能と圧縮機能とを併有し、包装容器ごみ排出部材14は包装容器ごみの排出機能と圧縮機能とを併有しているので、部品点数及び車両コストの低減を図るとともに、構造を簡素化して信頼性を向上することができる。
【0047】
また、本実施形態のごみ収集車1によれば、生ごみを圧縮する際に、生ごみ排出部材11に押圧された生ごみがごみ分離箱4側へ逆流することがないようにしたので、逆流した生ごみによりごみ分離箱4等を損壊するおそれはない。
【0048】
また、本実施形態のごみ収集車1によれば、作業者は、ごみ収容部2の上部に設けられたごみ投入部3まで、自力で生ごみ入り包装容器を運ぶ必要はなく、搬送投入機構21によりごみ投入部3に生ごみ入り包装容器を投入することができる。また、包装容器ごみ収容箱6の前方に搬送投入機構21が備えたので、車両の車幅方向寸法を大きくすることなく、限られた荷台スペースに搬送投入機構21を備えることができる。従って、ごみ投入時における作業者の負担を軽減することができるし、搬送投入機構21により車両の車幅方向寸法が大きくなることもない。
【0049】
尚、前記実施形態においては、破砕機構7を、左右一対の回転軸7aと、各回転軸7aに設けられた複数の破砕具7bとから構成したものを示したが、生ごみ入り包装容器を破砕するものであれば、破砕機構はどのような構成であってもよい。
【0050】
