Description

【0001】
【発明の属する技術分野】
本発明は、商品を積層する載置台に対してその前後方向に沿って往復移動するプッシャを備え、このプッシャを最下位商品に押し当てながら前方へ移動させることにより、当該最下位商品の搬出を行う商品搬出装置に関し、特に、タバコ等の箱型商品を販売する自動販売機に好適な商品搬出装置に関するものである。
【0002】
【従来の技術】
この種の商品搬出装置としては、例えば、図19に示すものが知られている。この商品搬出装置は、商品1を積層する載置台2に対してその前後方向に沿って移動するプッシャ3を備え、このプッシャ3を最下位商品1に押し当てながら移動させることにより、当該最下位商品1の搬出を行うものである。プッシャ3は、図示せぬナピアネジ機構の移動体に連係されており、該ナピアネジ機構の駆動によって往復移動することが可能である(例えば、特許文献1参照)。
【0003】
また、図20に示す商品搬出装置では、無端状の搬出ベルト11にプッシャ12を設け、該搬出ベルト11を周回させることによってプッシャ12を載置台13に対してその前後方向に沿って移動させ、積層された商品14を最下位に位置するものから搬出するようにしている(例えば、特許文献2参照)。
【0004】
これらいずれの商品搬出装置においても、プッシャ3,12によって載置台2,13の前方側へ移動された最下位商品1,14は、前傾姿勢(後端側が持ち上がる姿勢)となった状態で当該載置台2,13から搬出されることになり、例えば自動販売機の商品取出口(図示せず)から取り出すことができるようになる。
【0005】
【特許文献1】
特開2000−247424号公報
【特許文献2】
特開平6−20147号公報
【0006】
【発明が解決しようとする課題】
ところで、上記のような商品搬出装置にあっては、プッシャ3,12の駆動方法に関わらず、商品1,14を積層する載置台2,13の前方域に当該商品1,14が前傾姿勢となって搬出できるだけの奥行き寸法を確保する必要がある。このため、商品搬出装置の奥行き寸法を短縮化し、例えば適用する自動販売機の小型化を図るためには、載置台2,13の奥行き寸法を短縮化することが考えられる。
【0007】
しかしながら、載置台2,13の奥行き寸法を単に短縮化した場合には、積層した商品1,14の安定性が損なわれ、例えば自動販売機が揺すられると商品1,14が載置台2,13から落下し、そのまま商品取出口から取り出されてしまう虞れがある。特に、商品1,14の積層数が少なくなった場合には、商品1,14に加わる荷重も減少することになるため、上述した問題が一層顕著となる。
【0008】
本発明は、上記実情に鑑みて、積層した商品の安定性を損なうことなく、奥行き寸法の短縮化を図ることのできる商品搬出装置を提供することを目的とする。
【0009】
【課題を解決するための手段】
上記目的を達成するために、本発明の請求項1に係る商品搬出装置は、商品を積層する載置台に対してその前後方向に沿って往復移動するプッシャを備え、このプッシャを最下位商品に押し当てながら前方へ移動させることにより、当該最下位商品の搬出を行う商品搬出装置において、前記載置台の前方域に突出した場合に最下位商品の前端部を支持する一方、退避移動した場合に最下位商品の搬出を許容する待機支持部材と、前記載置台に対してスライド可能に配設し、前記載置台に対して後端位置に占位した場合に前記待機支持部材を前記載置台の前方域に突出した状態に保持する一方、前記載置台に対して前端位置に占位した場合には前記待機支持部材が最下位商品の搬出域から退避する方向への移動を許容する待機支持駆動体と、前記待機支持駆動体から前記プッシャの移動域に臨む態様で配設し、前記プッシャが前方への移動を開始した場合に該プッシャに係合することにより、後端位置に占位した待機支持駆動体を前端位置まで移動させ、かつ該待機支持駆動体が前端位置に占位した場合には退避移動することによって前記待機支持駆動体に対する前記プッシャの前方への移動を許容する第1当接片と、前記待機支持駆動体から前記プッシャの移動域に臨む態様で配設し、前記プッシャが後方への移動を開始した場合に該プッシャに係合することにより、前端位置に占位した待機支持駆動体を後端位置まで移動させ、かつ該待機支持駆動体が後端位置に占位した場合には退避移動することによって前記待機支持駆動体に対する前記プッシャの後方への移動を許容する第2当接片とを備えたことを特徴とする。
【0010】
また、本発明の請求項2に係る商品搬出装置は、上述した請求項1において、前記第1当接片および前記第2当接片が、それぞれ前記待機支持駆動体に一体形成し、かつ前記プッシャからの押圧力により弾性的に変形することによって退避移動するものであることを特徴とする。
【0011】
【発明の実施の形態】
以下に添付図面を参照して、本発明に係る商品搬出装置の好適な実施の形態について詳細に説明する。
【0012】
図1は、本発明の実施の形態である商品搬出装置を示したもので、図8〜図18は、その適用例を示したものである。ここで例示する商品搬出装置は、タバコ等の箱型の商品を販売する自動販売機に適用され、商品を収納する商品収納コラム30の下端部に配置されるもので、ABS(アクリロニトリル・ブタジエン・スチレン)樹脂等の合成樹脂によって成形したハウジング40を備えている。
【0013】
ハウジング40は、左右一対のケース40L,40Rを互いに接合させることによって構成したものである。このハウジング40には、垂直部41および載置台部42を設けてある。垂直部41は、自動販売機の商品収納コラム30を構成する後壁31に嵌め込まれる部分であり、上下方向に沿って延在している。載置台部42は、商品が積層される載置台を構成する部分であり、垂直部41のほぼ中間となる部分から前方に向けてほぼ水平に延在している。この載置台部42の垂直部41からの前後方向長さは、搬出すべき商品の前後方向長さよりも短く構成してある。載置台部42の上面は、商品収納コラム30を構成する前壁32に設けた搬出口33の上縁に対して最厚商品、すなわち販売すべき商品のうち最も高さの大きいものの搬出を可能にし、かつ最薄商品、すなわち販売すべき商品のうち最も高さの小さいものを唯一搬出できる高さに設定してある。載置台部42の上面中央部には、後述するプッシャ50を突出させるための往復溝43が前後方向に沿って全域に形成してあるとともに、左ケース40Lの上面には、後述する売切検知レバー60を出没させるための検知溝44が前後方向に沿って形成してある。また、垂直部41の前面における載置台部42の上面との会合部には、後述するプッシャ50の押板51を収容するための格納凹部45が設けてある。
【0014】
また、上述したハウジング40には、図2に示すように、右ケース40Rに往復移動機構70およびプッシャ50が設けてある一方、図3に示すように、左ケース40Lに売切検知レバー60、駆動源80、案内溝90、待機支持部材100、搬出支持部材110、待機支持駆動体120および搬出支持駆動体130が設けてある。
【0015】
往復移動機構70は、いわゆるナピアネジ機構と称されるもので、図2および図5〜図7に示すように、軸部材71および往復移動体72を備えている。
【0016】
軸部材71は、周面に一連の往復螺旋溝711を有した円柱状部材である。この軸部材71は、載置台部42の内部に前後方向に沿ってほぼ水平に配設してあり、軸心を中心として回転することが可能である。軸部材71の基端部には、ドリブンギヤ712が一体に成形してある。このドリブンギヤ712は、右ケース40Rに収納させた歯車列73に歯合するものである。
【0017】
往復移動体72は、ブロック状を成すもので、その前端面から後端面に亘る部位にガイド孔721を有している。この往復移動体72は、ガイド孔721に軸部材71を嵌挿させることにより、軸部材71の軸心方向に沿って移動が可能である一方、右ケース40Rの載置台部42を構成する下壁に対して、下端面に設けた移動当接部722が近接配置してあり、軸部材71に対する軸心回りの回転を規制してある。
【0018】
また、往復移動体72には、その左側面に案内突部723を一体に設けてあるとともに、その上端面から下端面に亘る部位に収容孔724を設けてある。
【0019】
案内突部723は、円柱状を成すもので、往復移動体72の上端前方隅部から左方に向けてほぼ水平に突設してある。
【0020】
収容孔724は、その軸心をガイド孔721の軸心に対して直交させる態様で形成したもので、その上端部周面に一対の弾性爪片725を備えている。これら一対の弾性爪片725は、往復移動体72と一体に成形したもので、個々の上端部に爪部725aを有している。爪部725aは、互いに内方に向けて略直角に突出した後、上方に向けて漸次外方に傾斜する形状を成しており、弾性爪片725が常態にある場合に収容孔724の内周面から内方に向けて突出する一方、弾性舌片が外方に向けて弾性的に変形した場合に収容孔724の内周面よりも外方に位置するように形成してある。
【0021】
この収容孔724には、回転駒74を収容させてある。回転駒74は、往復移動体72の収容孔724に対して回転可能に嵌合する円柱状の太径部741と、この太径部741の上端に設けた細径部742と、太径部741の下端に設けた従動片743とを一体に成形したものである。従動片743は、軸部材71の往復螺旋溝711よりも幅を狭く、下端縁を円弧状に形成したもので、往復螺旋溝711に位置させた状態で軸部材71を軸心回りに回転させた場合に、該往復螺旋溝711に沿って移動することが可能である。この回転駒74は、従動片743を下方に向けた状態で収容孔724に挿入すれば、太径部741が爪部725aに摺接することにより弾性爪片725が弾性的に拡開変形し、従動片743を軸部材71の往復螺旋溝711に位置させることができるとともに、自己の軸心回りに回転することによって従動片743を軸部材71に対して適宜傾動させることが可能である。従動片743が軸部材71の往復螺旋溝711に位置すると、弾性爪片725の爪部725aが細径部742に位置して弾性爪片725が復帰移動し、各爪部725aが太径部741と細径部742との間の段部に係合することになり、回転駒74の収容孔724からの脱落が阻止されるようになる。すなわち、本実施の形態の往復移動機構では、従動片743を一体に形成した回転駒74を往復移動体72の収容孔724に挿入しさえすれば、該従動片743を脱落することなく往復移動体72に保持させることができるようになり、従来のものに比べてその組立作業性が著しく向上するようになる。
【0022】
プッシャ50は、往復溝43を通じて載置台部42の上面から突出し、商品を押し出すためのもので、図5に示すように、板状を成す主板52に押板51および突条部53を有して構成してある。押板51は、商品を押し出す際に該商品に直接当接する部分であり、主板52の上端前部から左右方向に沿ってほぼ水平に延在している。この押板51の長さは、ハウジング40に設けた格納凹部45に収容できる長さに形成してある。突条部53は、主板52の左側面からその下端縁に沿って突出した部分である。
【0023】
また、プッシャ50の主板52には、案内凹所となる溝孔54を設けてある。溝孔54は、往復移動体72に設けた案内突部723の外径と同一の幅を有した長孔であり、上方に向けて漸次前方に傾斜延在している。この溝孔54は、案内突部723を上端に位置させた場合に載置台部42の上面からのプッシャ50の突出量が最薄商品よりも低い位置となる一方、案内突部723を下方に位置させた場合に載置台部42の上面からのプッシャ50の突出量が最厚商品の高さの1/2を超える位置となるように形成してある。
【0024】
売切検知レバー60は、図1、図3および図6に示すように、その先端部が検知溝44から載置台部42の上面に出没する態様で左ケース40Lに揺動可能に支承させ、該検知溝44から突出した場合に、図示せぬセンサを通じて載置台部42の上面に商品が無いことを検出するものである。
【0025】
駆動源80は、電動モータ等の回転アクチュエータであり、その出力軸にドライブギヤ81を備えている。この駆動源80は、左右のケース40L,40Rを互いに接合させた際に、右ケース40Rの歯車列73に対してドライブギヤ81を歯合させることのできる位置に設けてある。
【0026】
案内溝90は、左右のケース40L,40Rを互いに接合させた際にプッシャ50に設けた突条部53を収容し、該突条部53を介してプッシャ50を載置台部42の前後方向に沿って案内するための溝状部である。図3からも明らかなように、この案内溝90は、後端側となる部分が載置台部42の下方においてほぼ水平に延在する一方、前端側となる部分が上方に向けて延在している。案内溝90の後端側となる部分は、載置台部42の上面からのプッシャ50の突出量が最薄商品の高さの小さいものよりも低くなるように形成してある一方、上方に向けて延在する部分は、載置台部42の上面からのプッシャ50の突出量が最厚商品の高さの1/2を超えるように形成してある。
【0027】
待機支持部材100は、図1および図4に示すように、円筒状を成す待機軸受部101の周面に待機支持部102および待機作用部103を有したもので、該待機軸受部101を介して左ケース40Lの前端部に揺動可能に配設してある。待機支持部102は、待機軸受部101の周面から径外方向に向けて延在した後、一旦右ケース40R側に屈曲し、さらに径外方向に向けて延在したもので、最も上方に揺動させた場合に、その先端部が載置台部42に設けた往復溝43の延長上に位置している。待機支持部102の先端部には、ストッパ部104を設けてある。このストッパ部104は、待機支持部102からほぼ直角となる方向に屈曲した部分であり、待機支持部102を最も上方に揺動させた場合に載置台部42の上面から突出し、かつ垂直部41からの前後方向長さが商品の前後方向長さよりも大きくなるように形成してある。待機作用部103は、待機支持部102を最も上方に揺動させた場合に待機軸受部101の周面から後方に向けて延在した部分である。
【0028】
搬出支持部材110は、円筒状を成す搬出軸受部111の周面に搬出支持部112および搬出作用部113を有したもので、該搬出軸受部111を介して待機軸受部101と同一軸心上となる位置に揺動可能に配設してある。搬出支持部112は、搬出軸受部111の周面から径外方向に向けて延在した後、一旦右ケース40R側に屈曲し、さらに径外方向に向けて幅広に延在したもので、最も上方に揺動させた場合に、その先端部が載置台部42の前端と待機支持部材100のストッパ部104との間に位置している。この搬出支持部112は、待機支持部102とともに最も上方に揺動させた場合に待機支持部102よりも上方側に位置し、その下面に待機支持部102が当接するように形成してある。搬出作用部113は、搬出支持部112を最も上方に揺動させた場合に搬出軸受部111の周面から後方に向けて延在した部分である。
【0029】
待機支持駆動体120は、図1、図3および図4に示すように、上下方向に沿って前後に延びるプレートの待機基部121と、この待機基部121の先端から側方に向けて屈曲延在した待機規制部122とを備えたもので、該待機規制部122を待機支持部材100の待機作用部103に対応させた状態で載置台部42の内部にその前後方向に沿って移動可能に配設してある。
【0030】
この待機支持駆動体120は、載置台部42に対してその後端側となる位置に占位した場合に、図9に示すように、待機規制部122の下端面が待機作用部103の突出端部上面に当接し、待機支持部材100を最も上方に揺動させた状態に保持する一方、載置台部42に対してその前端側となる位置に占位した場合に、図11に示すように、待機規制部122が待機軸受部101よりも前端側に位置し、待機支持部材100の下方への揺動を許容するように機能する。
【0031】
また、この待機支持駆動体120には、図3および図4に示すように、第1当接片123および第2当接片124を設けてある。第1当接片123および第2当接片124は、それぞれ待機基部121から右ケース40R側に突出する態様で一体に形成したもので、互いに同一の高さとなる位置に並設してある。これら第1当接片123および第2当接片124は、待機基部121の前後方向に沿った押圧力が与えられた場合に弾性的に変形するように適宜屈曲形成してあり、それぞれ左ケース40Lにおいて案内溝90よりも上方となる位置に設けた一対の上方開口溝46,47を介してプッシャ50における主板52の移動域に臨んで配置してある。
【0032】
搬出支持駆動体130は、図4に示すように、上下方向に沿って前後に延びるプレート状の搬出基部131と、この搬出基部131の先端から側方に向けて屈曲延在した搬出規制部132と、搬出基部131の基端から下方に向けて屈曲延在した検出突部133と、搬出基部131の下端から搬出規制部132とは逆方向に屈曲延在した受圧板部134とを備えたもので、搬出規制部132を搬出支持部材110の搬出作用部113に対応させた状態で載置台部42の内部にその前後方向に沿って移動可能に配設してある。検出突部133は、左ケース40Lに配設したストローク検出センサ140をON/OFFさせるためのものである。受圧板部134には、その前端に前方受圧突起135を設けてあるとともに、その後端に後方受圧突起136を設けてある。これら前方受圧突起135および後方受圧突起136は、待機支持駆動体120に設けた第1当接片123および第2当接片124の相互間隔よりも十分に大きな間隔を持って形成してあり、左ケース40Lにおいて案内溝90よりも下方となる位置に設けた下方開口溝48を介してそれぞれ往復移動体72における移動当接部722の移動域に臨んで配置してある。
【0033】
この搬出支持駆動体130は、載置台部42に対してその後端側となる位置に占位した場合に、図9に示すように、搬出規制部132の下端面が搬出作用部113の突出端部上面に当接し、搬出支持部材110を最も上方に揺動させた状態に保持する一方、載置台部42に対してその前端側となる位置に占位した場合に、図15に示すように、搬出規制部132が搬出軸受部111よりも前端側に位置し、搬出支持部材110の下方への揺動を許容するように機能する。また、図8に示すように、搬出支持駆動体130が載置台部42に対して後端側となる位置に占位した場合には、ストローク検出センサ140に対して検出突部133が後方に位置し、該ストローク検出センサ140をOFFした状態に保持する一方、搬出支持駆動体130が載置台部42に対して前端側となる位置に占位した場合には、図14に示すように、検出突部133がストローク検出センサ140をONする位置となる。
【0034】
なお、上述した軸部材71、往復移動体72、歯車列73、回転駒74、プッシャ50、売切検知レバー60、ドライブギヤ81、待機支持部材100、搬出支持部材110、待機支持駆動体120、搬出支持駆動体130に関しては、それぞれをポリアセタール等の合成樹脂によって成形してある。
【0035】
図8〜図18は、上述した商品搬出装置を適用する自動販売機において、特に最薄商品200を販売する際の動作を示したものである。以下、これらの図を適宜参照しながら本実施の形態の商品搬出装置について詳述する。
【0036】
まず、上記商品搬出装置では、図8に示すように、往復移動体72が載置台部42の最も後端側に位置し、移動当接部722の後端面に搬出支持駆動体130の後方受圧突起136が当接した状態が商品販売待機状態となっている。
【0037】
この商品販売待機状態においては、待機支持駆動体120および搬出支持駆動体130がそれぞれ載置台部42の最も後端側に位置している。従って、ストローク検出センサ140に対して検出突部133が後方に位置し、該ストローク検出センサ140がOFF状態となる。また、図9に示すように、待機支持駆動体120の待機規制部122が待機支持部材100における待機作用部103の上面に位置し、待機支持部材100が最も上方に揺動することによって待機支持部102が載置台部42の上面延長上に位置することになるとともに、搬出支持駆動体130の搬出規制部132が搬出支持部材110における搬出作用部113の上面に位置し、搬出支持部材110が最も上方に揺動することによって搬出支持部112が載置台部42の上面延長上に位置することになる。この結果、載置台部42の前端から突出する商品200の前端部下面がこれら待機支持部材100および搬出支持部材110によって支持されるとともに、待機支持部材100のストッパ部104が商品200の前端面に係合することになり、例えば悪意のあるものが自動販売機を前後方向に揺すったとしても、商品200の残数に関わらず、載置台部42の上面に積層した商品200の積層姿勢が乱れたり、搬出口33に落下する虞れがない。
【0038】
上述した商品販売待機状態から販売指令が与えられると、商品搬出装置の図示せぬ制御部は、駆動源80を駆動することにより、ドライブギヤ81、歯車列73およびドリブンギヤ712を介して往復移動機構70の軸部材71を一方方向に向けて回転させる。軸部材71が回転すると、その往復螺旋溝711に沿って従動片743が往動することにより、往復移動体72が載置台部42の前端方向に向けて直線的な移動を開始する。
【0039】
ここで、従動片743の傾動に伴って回転駒74が回転した場合にも、一対の弾性爪片725の爪部725aが回転駒74に係合しているため、当該回転駒74が往復移動体72の収容孔724から脱落することはない。
【0040】
往復移動体72の移動は、案内突部723を介してプッシャ50に伝達されることになり、結局、プッシャ50が案内溝90に沿って前端側に移動を開始することになる。
【0041】
プッシャ50が前端側に移動を開始すると、図10に示すように、プッシャ50における主板52の前端が待機支持駆動体120の第1当接片123に当接することになり、該第1当接片123を介して待機支持駆動体120を載置台部42の前端側に移動させる。この結果、図11に示すように、待機支持駆動体120の待機規制部122が待機軸受部101よりも前端側に位置し、待機支持部材100の下方への揺動が許容されることになるため、その自重により待機支持部材100が下方へ揺動した状態に保持され、載置台部42に対する最下位商品200の前端側への移動が許容されるようになる。但し、搬出支持部材110に関しては、搬出支持駆動体130が継続して載置台部42の後端側に位置しているため、載置台部42の上面延長上に位置した状態のままとなる。
【0042】
上述した状態からさらに軸部材71が回転すると、往復移動体72が前端側へ移動するため、プッシャ50も前端側へ移動することになる。この場合、待機支持駆動体120が載置台部42の前端側に移動した後においては、プッシャ50の主板52が第1当接片123、さらには第2当接片124に当接した場合、これら第1当接片123および第2当接片124が弾性的に変形し、プッシャ50における主板52の移動域から待避することになるため、待機支持駆動体120の位置を変更することなくプッシャ50の前端側への移動が順次許容されるようになる。なお、これら第1当接片123および第2当接片124は、プッシャ50が通過した後において弾性復帰し、再びプッシャ50における主板52の移動域に突出した状態となるのはいうまでもない。
【0043】
プッシャ50が前端側に移動すると、やがてプッシャ50の押板51が最下位商品200の後端面に当接し、載置台部42に対して最下位商品200を前端側へ押し出すようになる。この場合、上述したように、プッシャ50の突条部53が案内溝90の後端側となる部分に位置している間においては、載置台部42の上面からのプッシャ50の突出量が最薄商品200の高さよりも小さくなっているため、プッシャ50の押板51が次販売商品200の後端面に当接することはなく、最下位商品200のみが前端側へ押し出されることになる。
【0044】
ここで、上述した動作の間、載置台部42の前端からの最下位商品200の突出長さが全長の1/2を超えると、本来であれば、当該最下位商品200が前傾姿勢となり、プッシャ50の押板51が後端面から外れてしまう場合がある。また、最薄商品200の場合には、最下位商品200とともに次販売商品200が載置台部42の上面において前傾姿勢となり、そのまま2つの商品200が搬出口33から落下する虞れがある。
【0045】
しかしながら、本実施の形態の商品搬出装置によれば、図12に示すように、プッシャ50の前端側への移動が進行すると、やがてプッシャ50が載置台部42の上面に対して上動し、最下位商品200の後端面に対してより高い位置でこれを押し出すようになり、当該最下位商品200の搬出が安定したものとなる。しかも、プッシャ50の前端側への移動が進行した状態であっても、最下位商品200の前端部下面が搬出支持部材110によって継続的に支持されるため、図13に示すように、プッシャ50が十分に前端側へ移動した時点で初めて最下位商品200が前傾姿勢となる一方、次販売商品200が後傾姿勢となる。従って、奥行き寸法の短縮化を図るべく、載置台部42の前後方向長さを搬出すべき商品の前後方向長さよりも短く構成した商品搬出装置であっても、プッシャ50の押板51が初期の状態において商品200の後端面から外れてしまう事態を防止できるとともに、2つの商品200が同時に搬出される事態を招来する虞れもない。
【0046】
さらに、最薄商品200の搬出を行う場合、本実施の形態の商品搬出装置によれば、前端側へ移動する途中においてプッシャ50が最下位商品200に代わって次販売商品200の下面に当接することになるため、最下位商品200に加わる荷重を減じることができるようになる。従って、最下位商品200の前端部が上方に跳ね上げられる事態を防止できるばかりでなく、最下位商品200が前傾姿勢を取り易くなり、搬出姿勢を安定化して商品詰まりを招来する虞れもない。
【0047】
図13に示すように、最下位商品200が前傾姿勢となるまでプッシャ50が移動した状態においては、往復移動体72に設けた移動当接部722の前端面が搬出支持駆動体130の前方受圧突起135に当接し、プッシャ50の移動とともに搬出支持駆動体130が前端側へ移動することになる。この結果、図15に示すように、搬出支持駆動体130の搬出規制部132が搬出軸受部111よりも前端側に位置し、搬出支持部材110の下方への揺動が許容されることになるため、その自重により搬出支持部材110が下方へ揺動した状態に保持される。つまり、図14に示すように、最下位商品200が搬出口33を通じて搬出される際には、待機支持部材100および搬出支持部材110の双方が下方に揺動し、最下位商品200の搬出域から待避することになるため、これら待機支持部材100および搬出支持部材110が最下位商品200の搬出を妨げる虞れがない。
【0048】
しかも、往復移動体72とプッシャ50との間は、上方に向けて載置台部42の前端側に傾斜する溝孔54を介して連係してある。従って、図14に示すように、往復移動体72が載置台部42の内部において軸部材71の前端部に達した場合、プッシャ50を載置台部42の前端から突出するように移動させることができるようになり、最下位商品200の搬出がより確実となる。
【0049】
また、次販売商品200の下面に当接したプッシャ50は、図14に示すように、載置台部42の上面と、後傾した次販売商品200の前端面下縁との間に最下位商品200の高さよりも大きな間隙を確保することになる。従って、最下位商品200が前傾姿勢となって載置台部42から搬出される際に次販売商品200が当該最下位商品200に対して影響を及ぼすこともなく、安定した搬出を行うことが可能となる。
【0050】
図14に示すように、搬出支持駆動体130が載置台部42の前端側に移動すると、検出突部133がストローク検出センサ140の検出子を押圧し、該ストローク検出センサ140をONする。ストローク検出センサ140からON信号を与えられた図示せぬ制御部は、駆動源80による軸部材71の回転を一旦停止し、つまりプッシャ50を載置台部42の前端部で一旦停止させ、その後、再び駆動源80を駆動することにより、軸部材71を同方向に回転させて往復移動体72の移動を再開する。このとき、軸部材71の前端部に達した往復移動体72は、従動片743が往復螺旋溝711に沿って軸部材71を復動することにより、載置台部42の後端方向に向けて直線的な移動を開始し、結局、プッシャ50を案内溝90に沿って後端側に移動させることになる。
【0051】
プッシャ50が後端側に移動を開始すると、図16に示すように、プッシャ50における主板52の前端が待機支持駆動体120の第2当接片124に当接することになり、該第2当接片124を介して待機支持駆動体120を載置台部42の後端側に移動させる。この結果、図17に示すように、待機支持駆動体120の待機規制部122が待機軸受部101を超えて後端側に移動し、待機作用部103を介して待機支持部材100を最も上方に揺動させることにより、待機支持部102が再び載置台部42の上面延長上に位置することになる。このとき、待機支持部材100は、上方に向けて揺動する際に、搬出支持部材110の下面に当接することにより、当該搬出支持部材110をも最も上方に揺動させ、搬出支持部112を載置台部42の上面延長上に位置させるようになる。この結果、図18に示すように、プッシャ50の後端側への移動に伴って次販売商品200が前傾姿勢となった場合であっても、これら待機支持部材100および搬出支持部材110によって次販売商品200を支持することができるとともに、待機支持部材100のストッパ部104が次販売商品200の前端面に係合することになり、搬出口33に落下する事態を招来する虞れがない。
【0052】
ここで、上記商品搬出装置によれば、上述したように、プッシャ50が最も前端側へ移動した後、暫時駆動源80の駆動を停止し、その後にプッシャ50の後端側への移動を開始するようにしているため、最下位商品200が確実に搬出された後に、待機支持部材100や搬出支持部材110が上方に揺動されることになる。従って、これら上方に揺動する待機支持部材100や搬出支持部材110と最下位商品200とが相互に干渉する虞れはなく、相互干渉による商品詰まりが招来されることもない。
【0053】
なお、待機支持駆動体120が載置台部42の後端側に移動した後においては、プッシャ50の主板52が第2当接片124、さらには第1当接片123に当接した場合、これら第2当接片124および第1当接片123が弾性的に変形し、プッシャ50における主板52の移動域から待避することになるため、待機支持駆動体120の位置を変更することなくプッシャ50の後端側への移動が順次許容されるようになる。また、これら第2当接片124および第1当接片123は、プッシャ50が通過した後において弾性復帰し、再びプッシャ50における主板52の移動域に突出した状態となる。
【0054】
図18に示すように、プッシャ50が載置台部42の後端側まで移動すると、往復移動体72に設けた移動当接部722の後端面が搬出支持駆動体130の後方受圧突起136に当接し、プッシャ50の移動とともに搬出支持駆動体130が後端側へ移動することになる。この結果、図9に示すように、搬出支持駆動体130の搬出規制部132が搬出作用部113の上面に位置し、搬出支持部材110が搬出支持駆動体130によって最も上方に揺動した状態に保持されることになる。
【0055】
最終的にプッシャ50が格納凹部45に収容された状態まで移動すると、再び、図8に示す商品販売待機状態に復帰し、この状態がストローク検出センサ140のOFFによって検出される。ストローク検出センサ140からOFF信号が与えられた図示せぬ制御部は、駆動源80によるプッシャ50の移動を停止し、販売指令を待つ。
【0056】
以降、販売指令が与えられた場合に上述した動作が繰り返し実行され、載置台部42に積層した商品200が下方に位置するものから順次一つずつ搬出されることになる。なお、プッシャ50の往復移動の際に売切検知レバー60が揺動することになるものの、往復移動体72を駆動する駆動源80が動作している間は、売切検知レバー60の揺動を検出した場合にもこれを無視するように構成してある。
【0057】
以上説明したように、本実施の形態の商品搬出装置によれば、載置台部42の前方域に突出した場合に最下位商品200の前端部を支持する一方、退避移動した場合に最下位商品200の搬出を許容する待機支持部材100を設けるようにしているため、商品販売待機状態において悪意のあるものが自動販売機を前後方向に揺すったとしても、商品200の残数に関わらず、載置台部42の上面に積層した商品200の積層姿勢が乱れたり、搬出口33に落下する虞れがなく、積層した商品200の安定性を損なうことなく、奥行き寸法の短縮化を図ることが可能になる。
【0058】
しかも、待機支持部材100を駆動するための待機支持駆動体120に第1当接片123および第2当接片124を一体に設け、プッシャ50の往動の際に第1当接片123に当接させることで待機支持部材100を退避移動させる一方、プッシャ50の復動の際に第2当接片124に当接させることで待機支持部材100を突出移動させるようにしているため、部品点数の増大を招来することなく動作タイミングの異なる待機支持部材100の動作を実現することができるようになる。
【0059】
なお、上述した実施の形態では、待機支持部材を揺動させるようにしているが、待機支持部材の移動態様は必ずしも揺動である必要はない。例えば、載置台に対して待機支持部材を出没可能に設けるようにしても同様の作用効果を奏することが可能である。
【0060】
また、上述した実施の形態では、第1当接片および第2当接片として弾性的に変形することによってプッシャの移動を許容するものを例示しているが、必ずしも弾性変形するものである必要はない。
【0061】
【発明の効果】
以上説明したように、本発明に係る商品搬出装置によれば、載置台の前方域に突出した場合に最下位商品の前端部を支持する一方、退避移動した場合に最下位商品の搬出を許容する待機支持部材を設けるようにしているため、商品販売待機状態において悪意のあるものが自動販売機を前後方向に揺すったとしても、商品の残数に関わらず、載置台の上面に積層した商品の積層姿勢が乱れたり、搬出口に落下する虞れがなく、積層した商品の安定性を損なうことなく、奥行き寸法の短縮化を図ることが可能になる。しかも、待機支持部材を駆動する待機支持駆動体に第1当接片および第2当接片を一体に設け、プッシャの往動の際に第1当接片に当接させることで待機支持部材を退避移動させる一方、プッシャの復動の際に第2当接片に当接させることで待機支持部材を突出移動させるようにしているため、部品点数の増大を招来することなく動作タイミングの異なる待機支持部材の動作を実現することができるようになる。

BACKGROUND OF THE INVENTION
The present invention is provided with a pusher that reciprocates along the front-rear direction with respect to a mounting table on which products are stacked, and by moving the pusher forward while pressing the pusher against the lowest product, the lowest product is unloaded. More particularly, the present invention relates to a product carry-out device suitable for a vending machine that sells box-type products such as cigarettes.
[0002]
[Prior art]
As this kind of product carry-out device, for example, the one shown in FIG. 19 is known. This product carry-out apparatus includes a pusher 3 that moves along the front-rear direction with respect to the mounting table 2 on which the product 1 is stacked, and moves the pusher 3 while pressing the pusher 3 against the lowest-order product 1, thereby The product 1 is carried out. The pusher 3 is linked to a moving body of a napier screw mechanism (not shown) and can reciprocate by driving the napier screw mechanism (see, for example, Patent Document 1).
[0003]
Further, in the product carry-out device shown in FIG. 20, the pusher 12 is provided on the endless carry-out belt 11, and the pusher 12 is moved along the front-rear direction with respect to the mounting table 13 by rotating the carry-out belt 11. The stacked products 14 are carried out from the lowest product (see, for example, Patent Document 2).
[0004]
In any of these commodity carry-out devices, the lowest-order products 1 and 14 that have been moved to the front side of the mounting tables 2 and 13 by the pushers 3 and 12 are in a state where they are in a forward inclined posture (a posture in which the rear end side is lifted). It will be carried out from the mounting bases 2 and 13, and can be taken out from, for example, a product outlet (not shown) of the vending machine.

[0006]
[Problems to be solved by the invention]
By the way, in the product carry-out device as described above, regardless of the driving method of the pushers 3 and 12, the products 1 and 14 are inclined forward in the front area of the mounting tables 2 and 13 on which the products 1 and 14 are stacked. Therefore, it is necessary to secure a depth dimension sufficient to carry out. For this reason, in order to shorten the depth dimension of the product carry-out device, for example, to reduce the size of the vending machine to be applied, it is conceivable to shorten the depth dimension of the mounting tables 2 and 13.
[0007]
However, when the depth dimensions of the mounting tables 2 and 13 are simply shortened, the stability of the stacked products 1 and 14 is impaired. For example, when the vending machine is shaken, the products 1 and 14 are placed on the mounting tables 2 and 13. There is a possibility that the product will fall off and be taken out from the product outlet as it is. In particular, when the number of stacked products 1 and 14 is reduced, the load applied to the products 1 and 14 is also reduced, so that the above-described problem becomes more prominent.
[0008]
In view of the above circumstances, an object of the present invention is to provide a product carry-out apparatus capable of reducing the depth dimension without impairing the stability of stacked products.
[0009]

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Exemplary embodiments of a product carry-out device according to the present invention will be described below in detail with reference to the accompanying drawings.
[0012]
FIG. 1 shows a commodity carry-out apparatus according to an embodiment of the present invention, and FIGS. 8 to 18 show application examples thereof. The product carry-out apparatus exemplified here is applied to a vending machine that sells box-type products such as cigarettes, and is arranged at the lower end of a product storage column 30 for storing products. ABS (Acrylonitrile butadiene A housing 40 formed of a synthetic resin such as styrene resin is provided.
[0013]
The housing 40 is configured by joining a pair of left and right cases 40L and 40R to each other. The housing 40 is provided with a vertical part 41 and a mounting table part 42. The vertical portion 41 is a portion that is fitted into the rear wall 31 constituting the product storage column 30 of the vending machine, and extends along the vertical direction. The mounting table portion 42 is a portion that constitutes a mounting table on which products are stacked, and extends substantially horizontally from a portion that is substantially in the middle of the vertical portion 41 toward the front. The length in the front-rear direction from the vertical part 41 of the mounting table 42 is configured to be shorter than the length in the front-rear direction of the product to be carried out. The top surface of the mounting table 42 can carry out the thickest product, that is, the product with the highest height among the products to be sold, with respect to the upper edge of the carry-out port 33 provided in the front wall 32 constituting the product storage column 30. In addition, the thinnest product, that is, the lowest product among the products to be sold, is set to a height that can be taken out only. A reciprocating groove 43 for projecting a pusher 50, which will be described later, is formed in the entire area along the front-rear direction at the center of the upper surface of the mounting table 42, and a sold-out detection, which will be described later, is formed on the upper surface of the left case 40L. A detection groove 44 for projecting the lever 60 is formed along the front-rear direction. In addition, a storage recess 45 for receiving a push plate 51 of a pusher 50 described later is provided at a meeting portion of the front surface of the vertical portion 41 with the upper surface of the mounting table portion 42.
[0014]
Further, as shown in FIG. 2, the housing 40 described above is provided with a reciprocating mechanism 70 and a pusher 50 in the right case 40R, while, as shown in FIG. A drive source 80, a guide groove 90, a standby support member 100, a carry-out support member 110, a standby support drive body 120, and a carry-out support drive body 130 are provided.
[0015]
The reciprocating mechanism 70 is a so-called Napier screw mechanism, and includes a shaft member 71 and a reciprocating body 72 as shown in FIGS. 2 and 5 to 7.
[0016]
The shaft member 71 is a cylindrical member having a series of reciprocating spiral grooves 711 on the peripheral surface. The shaft member 71 is disposed substantially horizontally along the front-rear direction inside the mounting table 42 and can rotate around the axis. A driven gear 712 is integrally formed at the base end portion of the shaft member 71. The driven gear 712 meshes with a gear train 73 housed in the right case 40R.
[0017]
The reciprocating body 72 has a block shape, and has a guide hole 721 at a portion extending from the front end surface to the rear end surface. The reciprocating body 72 can be moved along the axial direction of the shaft member 71 by fitting the shaft member 71 into the guide hole 721, while the lower part constituting the mounting table portion 42 of the right case 40 </ b> R. A moving contact portion 722 provided on the lower end surface is disposed close to the wall, and the rotation about the shaft center relative to the shaft member 71 is restricted.
[0018]
In addition, the reciprocating body 72 has a guide protrusion 723 integrally provided on the left side surface thereof, and a receiving hole 724 provided in a portion extending from the upper end surface to the lower end surface thereof.
[0019]
The guide protrusion 723 has a cylindrical shape, and protrudes substantially horizontally from the upper front corner of the reciprocating moving body 72 toward the left.
[0020]
The accommodation hole 724 is formed in such a manner that its axis is perpendicular to the axis of the guide hole 721, and has a pair of elastic claw pieces 725 on the peripheral surface of the upper end portion. The pair of elastic claw pieces 725 are formed integrally with the reciprocating moving body 72 and have claw portions 725a at the respective upper ends. The claw portions 725a have a shape that protrudes substantially inward toward each other inward and then gradually inclines outward toward the upper side. When the elastic claw piece 725 is in a normal state, While projecting inward from the peripheral surface, the elastic tongue piece is formed to be positioned outward from the inner peripheral surface of the accommodation hole 724 when the elastic tongue piece is elastically deformed outward.
[0021]
A rotating piece 74 is accommodated in the accommodation hole 724. The rotary piece 74 includes a cylindrical large-diameter portion 741 that is rotatably fitted in the accommodation hole 724 of the reciprocating moving body 72, a small-diameter portion 742 provided at the upper end of the large-diameter portion 741, and a large-diameter portion. A driven piece 743 provided at the lower end of 741 is integrally formed. The driven piece 743 is narrower than the reciprocating spiral groove 711 of the shaft member 71 and has a lower end edge formed in an arc shape, and rotates the shaft member 71 around the axis while being positioned in the reciprocating spiral groove 711. In this case, it is possible to move along the reciprocating spiral groove 711. When the rotary piece 74 is inserted into the receiving hole 724 with the driven piece 743 facing downward, the elastic claw piece 725 elastically expands and deforms due to the large diameter portion 741 slidingly contacting the claw portion 725a.

[0035]
FIGS. 8 to 18 show operations particularly when the thinnest product 200 is sold in the vending machine to which the above-described product carry-out device is applied. Hereinafter, the commodity carry-out device of the present embodiment will be described in detail with reference to these drawings as appropriate.
[0036]
First, in the product carry-out device, as shown in FIG. 8, the reciprocating moving body 72 is positioned on the most rear end side of the mounting table portion 42, and the rear pressure receiving pressure of the carry-out support driving body 130 on the rear end surface of the moving contact portion 722. The state in which the protrusion 136 is in contact is the product sales standby state.
[0037]
In this merchandise sales standby state, the standby support driving body 120 and the carry-out support driving body 130 are respectively located on the most rear end side of the mounting table portion 42. Therefore, the detection protrusion 133 is located behind the stroke detection sensor 140, and the stroke detection sensor 140 is turned off. Further, as shown in FIG. 9, the standby restriction portion 122 of the standby support driving body 120 is positioned on the upper surface of the standby action portion 103 of the standby support member 100, and the standby support member 100 swings upward to support standby. The portion 102 is positioned on the upper surface extension of the mounting table portion 42, the unloading restriction portion 132 of the unloading support driving body 130 is positioned on the upper surface of the unloading operation portion 113 in the unloading support member 110, and the unloading support member 110 is The carry-out support part 112 is positioned on the upper surface extension of the mounting table part 42 by swinging upward. As a result, the lower surface of the front end of the product 200 protruding from the front end of the mounting table 42 is supported by the standby support member 100 and the carry-out support member 110, and the stopper portion 104 of the standby support member 100 is placed on the front end surface of the product 200. For example, even if a malicious object shakes the vending machine in the front-rear direction, the stacking posture of the product 200 stacked on the upper surface of the mounting table 42 is disturbed regardless of the remaining number of products 200. There is no risk of falling to the carry-out port 33.
[0038]
When a sales command is given from the above-described merchandise sales standby state, a control unit (not shown) of the merchandise carry-out apparatus drives the drive source 80 to drive a reciprocating mechanism through the drive gear 81, the gear train 73, and the driven gear 712. 70 shaft members 71 are rotated in one direction. When the shaft member 71 rotates, the driven piece 743 moves forward along the reciprocating spiral groove 711, so that the reciprocating moving body 72 starts linear movement toward the front end direction of the mounting table portion 42.
[0039]
Here, even when the rotary piece 74 rotates as the driven piece 743 tilts, the claw portions 725a of the pair of elastic claw pieces 725 are engaged with the rotary piece 74, so that the rotary piece 74 moves back and forth. The body 72 does not fall out of the accommodation hole 724.
[0040]
The movement of the reciprocating body 72 is transmitted to the pusher 50 via the guide protrusion 723, and eventually, the pusher 50 starts moving along the guide groove 90 toward the front end side.
[0041]
When the pusher 50 starts to move to the front end side, as shown in FIG. 10, the front end of the main plate 52 in the pusher 50 comes into contact with the first contact piece 123 of the standby support driving body 120, and the first contact is made. The standby support driving body 120 is moved to the front end side of the mounting table portion 42 through the piece 123. As a result, as shown in FIG. 11, the standby restricting portion 122 of the standby support driving body 120 is positioned on the front end side of the standby bearing portion 101, and the standby support member 100 is allowed to swing downward. Therefore, the stand-by support member 100 is held in a state of swinging downward by its own weight, and the movement of the lowest-order product 200 to the front end side with respect to the mounting table portion 42 is allowed. However, regarding the carry-out support member 110, since the carry-out support driving body 130 is continuously located on the rear end side of the mounting table portion 42, it remains in a state of being positioned on the upper surface extension of the mounting table portion 42.
[0042]
When the shaft member 71 further rotates from the state described above, the reciprocating body 72 moves to the front end side, so that the pusher 50 also moves to the front end side. In this case, after the standby support driving body 120 moves to the front end side of the mounting table portion 42, when the main plate 52 of the pusher 50 contacts the first contact piece 123 and further the second contact piece 124, Since the first contact piece 123 and the second contact piece 124 are elastically deformed to be retracted from the movement range of the main plate 52 in the pusher 50, the pusher is not changed without changing the position of the standby support driving body 120. The movement to the front end side of 50 is sequentially allowed. Needless to say, the first abutting piece 123 and the second abutting piece 124 are elastically restored after the pusher 50 passes and project into the moving area of the main plate 52 in the pusher 50 again. .
[0043]
When the pusher 50 moves to the front end side, the push plate 51 of the pusher 50 eventually comes into contact with the rear end surface of the lowermost product 200 and pushes the lowermost product 200 toward the front end side with respect to the mounting table 42. In this case, as described above, the protrusion amount of the pusher 50 from the upper surface of the mounting table portion 42 is the maximum while the protruding portion 53 of the pusher 50 is positioned at the rear end side of the guide groove 90. Since it is smaller than the height of the thin product 200, the push plate 51 of the pusher 50 does not contact the rear end surface of the next sale product 200, and only the lowest product 200 is pushed out to the front end side.
[0044]
Here, during the above-described operation, if the protruding length of the lowest-order product 200 from the front end of the mounting table 42 exceeds 1/2 of the total length, the lowest-order product 200 assumes a forward leaning posture. The push plate 51 of the pusher 50 may come off from the rear end surface. In the case of the thinnest product 200, the next sale product 200 together with the lowest product 200 is inclined forward on the upper surface of the mounting table 42, and the two products 200 may fall from the carry-out port 33 as they are.
[0045]
However, according to the product carry-out device of the present embodiment, as shown in FIG. 12, when the pusher 50 moves toward the front end side, the pusher 50 eventually moves up with respect to the upper surface of the mounting table 42, This is pushed out at a higher position with respect to the rear end face of the lowest product 200, and the delivery of the lowest product 200 becomes stable. In addition, even when the pusher 50 moves to the front end side, the lower surface of the front end portion of the lowest-order product 200 is continuously supported by the carry-out support member 110. Therefore, as shown in FIG. Only when the product moves sufficiently to the front end side, the lowest-order product 200 assumes a forward leaning posture, while the next sale product 200 assumes a backward leaning posture. Therefore, in order to shorten the depth dimension, the push plate 51 of the pusher 50 is the initial one even in the product carry-out device configured so that the longitudinal length of the mounting table 42 is shorter than the longitudinal length of the product to be carried out. In this state, it is possible to prevent the product 200 from being detached from the rear end face, and there is no possibility of incurring a situation where the two products 200 are carried out simultaneously.
[0046]
Furthermore, when carrying out the thinnest product 200, according to the product carry-out device of the present embodiment, the pusher 50 abuts on the lower surface of the next sale product 200 in place of the lowest product 200 during the movement to the front end side. Therefore, the load applied to the lowest product 200 can be reduced. Therefore, not only can the situation where the front end of the lowest product 200 is flipped upwards, but the lowest product 200 can easily take a forward leaning posture, which can stabilize the carry-out posture and lead to product clogging. Absent.
[0047]
As shown in FIG. 13, in a state where the pusher 50 has moved until the lowest-order product 200 is in the forward leaning posture, the front end surface of the moving contact portion 722 provided in the reciprocating moving body 72 is the front of the carry-out support driving body 130. The unloading support driving body 130 moves to the front end side with the movement of the pusher 50 in contact with the pressure receiving projection 135. As a result, as shown in FIG. 15, the carry-out restricting portion 132 of the carry-out support driving body 130 is positioned on the front end side with respect to the carry-out bearing portion 111, and the downward swing of the carry-out support member 110 is allowed. Therefore, the carry-out support member 110 is held in a state of swinging downward by its own weight. That is, as shown in FIG. 14, when the lowest product 200 is carried out through the carry-out port 33, both the standby support member 100 and the carry-out support member 110 swing downward, and the carry-out area of the lowest product 200 is Therefore, there is no possibility that the standby support member 100 and the carry-out support member 110 prevent the lowest product 200 from being carried out.
[0048]
Moreover, the reciprocating body 72 and the pusher 50 are linked via a groove hole 54 that is inclined upward toward the front end side of the mounting table portion 42. Therefore, as shown in FIG. 14, when the reciprocating moving body 72 reaches the front end portion of the shaft member 71 inside the mounting table portion 42, the pusher 50 can be moved so as to protrude from the front end of the mounting table portion 42. It becomes possible to carry out the lowest order product 200 more reliably.
[0049]
Further, as shown in FIG. 14, the pusher 50 in contact with the lower surface of the next sale product 200 is the lowest product between the upper surface of the mounting table 42 and the lower edge of the front end face of the next sale product 200 tilted backward. A gap larger than the height of 200 is secured. Therefore, when the lowest product 200 is tilted forward and carried out from the mounting table 42, the next sale product 200 does not affect the lowest product 200 and can be stably carried out. It becomes possible.
[0050]
As shown in FIG. 14, when the carry-out support driving body 130 moves to the front end side of the mounting table portion 42, the detection protrusion 133 presses the detector of the stroke detection sensor 140 and turns on the stroke detection sensor 140. A control unit (not shown) to which an ON signal is given from the stroke detection sensor 140 temporarily stops the rotation of the shaft member 71 by the drive source 80, that is, temporarily stops the pusher 50 at the front end of the mounting table 42, and then By driving the drive source 80 again, the shaft member 71 is rotated in the same direction, and the movement of the reciprocating body 72 is resumed. At this time, the reciprocating body 72 that has reached the front end portion of the shaft member 71 moves toward the rear end direction of the mounting table portion 42 by the driven piece 743 returning the shaft member 71 along the reciprocating spiral groove 711. The linear movement is started, and eventually the pusher 50 is moved along the guide groove 90 to the rear end side.
[0051]
When the pusher 50 starts moving toward the rear end side, as shown in FIG. 16, the front end of the main plate 52 of the pusher 50 comes into contact with the second contact piece 124 of the standby support driving body 120, and the second contact The standby support driving body 120 is moved to the rear end side of the mounting table portion 42 through the contact piece 124. As a result, as shown in FIG. 17, the standby restricting portion 122 of the standby support driving body 120 moves to the rear end side beyond the standby bearing portion 101, and the standby support member 100 is moved to the uppermost position via the standby operation portion 103. By swinging, the standby support portion 102 is again positioned on the upper surface extension of the mounting table portion 42. At this time, when the standby support member 100 swings upward, the standby support member 100 abuts on the lower surface of the carry-out support member 110, thereby swinging the carry-out support member 110 to the uppermost position. It comes to be located on the upper surface extension of the mounting base part 42. As a result, as shown in FIG. 18, even when the next sale product 200 is in a forward leaning posture with the movement of the pusher 50 toward the rear end side, the standby support member 100 and the carry-out support member 110 The next sale product 200 can be supported, and the stopper 104 of the standby support member 100 is engaged with the front end surface of the next sale product 200, so that there is no possibility of causing a situation of falling to the carry-out port 33. .
[0052]
Here, according to the commodity carry-out device, as described above, after the pusher 50 has moved to the most front end side, the drive of the temporary drive source 80 is stopped, and then the pusher 50 starts to move to the rear end side. Therefore, after the lowest-order product 200 is reliably carried out, the standby support member 100 and the carry-out support member 110 are swung upward. Therefore, there is no possibility that the standby support member 100 or the carry-out support member 110 swinging upward and the lowest-order product 200 interfere with each other, and the product is not clogged due to the mutual interference.
[0053]
In addition, after the standby support driving body 120 moves to the rear end side of the mounting table portion 42, when the main plate 52 of the pusher 50 comes into contact with the second contact piece 124 and further with the first contact piece 123, Since the second contact piece 124 and the first contact piece 123 are elastically deformed and are retracted from the movement range of the main plate 52 in the pusher 50, the pusher is not changed without changing the position of the standby support driving body 120. The movement toward the rear end side of the 50 is sequentially allowed. In addition, the second contact piece 124 and the first contact piece 123 are elastically restored after the pusher 50 has passed, and again project into the moving area of the main plate 52 in the pusher 50.
[0054]
As shown in FIG. 18, when the pusher 50 moves to the rear end side of the mounting table portion 42, the rear end surface of the moving contact portion 722 provided on the reciprocating moving body 72 contacts the rear pressure receiving projection 136 of the carry-out support driving body 130. The unloading support driving body 130 moves to the rear end side as the pusher 50 moves. As a result, as shown in FIG. 9, the unloading restricting portion 132 of the unloading support driving body 130 is positioned on the upper surface of the unloading action portion 113, and the unloading support member 110 is swung upwards by the unloading support driving body 130. Will be retained.
[0055]
When the pusher 50 finally moves to the state where it is accommodated in the storage recess 45, the product sales standby state shown in FIG. 8 is restored again, and this state is detected by turning off the stroke detection sensor 140. A control unit (not shown) to which the OFF signal is given from the stroke detection sensor 140 stops the movement of the pusher 50 by the drive source 80 and waits for a sales command.
[0056]
Thereafter, when a sales command is given, the above-described operation is repeatedly executed, and the products 200 stacked on the mounting table 42 are sequentially carried out one by one from the one located below. Although the sold-out detection lever 60 is swung when the pusher 50 is reciprocated, the sold-out detection lever 60 is swung while the drive source 80 that drives the reciprocating body 72 is operating. Even if detected, this is ignored.
[0057]
As described above, according to the product carry-out device of the present embodiment, the front end portion of the lowest product 200 is supported when protruding to the front area of the mounting table 42, while the lowest product is moved when retracted. Since the standby support member 100 that allows the carry-out of the 200 is provided, even if a malicious thing shakes the vending machine in the front-rear direction in the product sales standby state, the product is placed regardless of the remaining number of the products 200. The stacking posture of the product 200 stacked on the upper surface of the pedestal portion 42 is not disturbed or falls to the carry-out port 33, and the depth dimension can be shortened without impairing the stability of the stacked product 200. become.
[0058]
In addition, the first abutment piece 123 and the second abutment piece 124 are integrally provided on the standby support driving body 120 for driving the standby support member 100, and the first abutment piece 123 is moved when the pusher 50 moves forward. While the standby support member 100 is retracted by contacting, the standby support member 100 is projected and moved by contacting the second contact piece 124 when the pusher 50 moves backward. It is possible to realize the operation of the standby support member 100 having different operation timings without causing an increase in the number of points.
[0059]
In the above-described embodiment, the standby support member is swung, but the movement mode of the standby support member is not necessarily rocking. For example, even if the standby support member is provided so as to be capable of appearing and retracting with respect to the mounting table, the same effect can be obtained.
[0060]
