【発明の属する技術分野】
この発明は、紙葉類の搬送される搬送路の一端に紙葉類収納部を設け、紙葉類を搬送路からこの紙葉類収納部へ搬入し、この中に積み重ねて収納したり、この紙葉類収納部に収納された紙葉類をここから搬送路を介して外部へ搬出するようにした紙葉類収納装置に関する。
【０００２】
【従来の技術】
紙葉類、例えば、紙幣の自動的な預け入れまたは払い出しなどに利用される紙幣自動預金／支払い機においては、預け入れの際には紙幣を選択的に収納部に搬入するとともに、払い出しの際には収納部に収納されている紙幣をここから搬出するようにする紙葉類収納装置が備えられている。
【０００３】
ここで、この種の従来の紙葉類収納装置について説明する。
【０００４】
図１７は従来の紙葉類収納装置の側面断面図、図１８は図１７のａ−ａ矢視断面図、図１９は図１７のｂ−ｂ矢視断面図である。なお、図１７は図１８のｄ−ｄ矢視断面図である。
【０００５】
従来の紙葉類収納装置は、図１７に示されるように紙幣Ｐが搬送される搬送路１と、この搬送路１の一端に設けられる、紙幣を積み重ねて収納する収納部２と、この収納部２内に表面が互いに接触されて積み重ねられた状態で収納された紙幣の最下部から支持するように昇降可能に配置されたステージ３とで構成されている。
【０００６】
搬送路１は、紙葉類の走行が可能な所定の空間をおいて互いに平行に相対して配置され筐体７に支持された上部搬送壁４と下部搬送壁５とよって形成されている。
【０００７】
下部搬送壁５には、図１８に示すように、搬送路１の紙幣の搬入または搬出の行われる側に開口部６、６がそしてその下流の収納部２側に開口部１０、１１および１２が設けられている。開口部６、６には両端が筐体７に回転可能に支持された回転軸８に設けられた搬送ローラ９、９が、その外周部の一部を下部搬送壁５から搬送路１内に露出するように配置されている。また、下流側の両側の開口部１０には羽根車１３と外周面が凹状に形成された凹形ローラ４４が、そして、開口部１２には、羽根車１８と外周面が凹状に形成された凹形ローラ４５がそれぞれ配置されている。これらの羽根車と凹形ローラは、それぞれ回転軸８と平行にかつ筐体７に回転可能に支持された回転軸１５および２０に設けられている。中央の開口部１１には、回転軸８と平行かつ両端が下部搬送壁５に支持された軸１６に回転可能に設けられたゲートローラ１７が配置されている。
【０００８】
羽根車１３、１８は弾性材料からなる複数枚の羽根１３ａ、１８ａを心棒に等間隔で放射状に取り付けた構成となっている。
【０００９】
上部搬送壁４側において、回転軸２３、２５、２６および２８が両端部を筐体７に回転自在に支持されており、それぞれ搬送ローラ２４、２１、２７および２９がそれぞれ外周部の一部を上部搬送壁の開口からから搬送路１内へ露出するように配置されている。搬送ローラ２１、２７、２９のそれぞれの外周部には所定の円周角だけ摩擦部材２１ａ、２７ａ、２９ａが設けられている。これらの摩擦部材２１ａ、２７ａ、２９ａは、紙幣Ｐを間欠的に搬送するために設けられている。
【００１０】
搬送路１内の上下の対となるローラ、すなわち搬送ローラ２４、２４と搬送ローラ６、６および搬送ローラ２１とゲートローラ１７は互いに接触して回転し、紙幣を間に挟んで搬送する。ゲートローラ１７は、コイルスプリング２２により搬送ローラ２１に向けて付勢されている。
【００１１】
上部搬送壁４における回転軸２５の筐体７から突出する両端部には、駆動プーリ３０および従動プーリ３１と、下部搬送壁５の回転軸１５、２０に設けられたギア３２、３３に噛み合うギア３４、３５とが設けられている。回転軸２６の筐体７から突出する両端部には、従動プーリ３６と駆動プーリ３７とが設けられ、従動プーリ３６と駆動プーリ３０との間にベルト３８が巻き掛けられている。さらに、回転軸２8の筐体７から突出する一端部には従動プーリ３９が設けられ、この従動プーリ３９と駆動プーリ３７との間にベルト４０が巻き掛けられている。なお、従動プーリ３１には図示が省略されている駆動用モータに結合された駆動プーリとの間にベルトが巻き掛けられ、駆動モータは、図示が省略されている制御装置からの制御信号により回転が制御される。
【００１２】
駆動モータが制御信号に基づき作動状態とされると、駆動モータの回転力が従動プーリ３１を介して回転軸２５と駆動プーリ３０および従動プーリ３６を介して回転軸２６と、駆動プーリ３７および従動プーリ３９を介して回転軸２８とに伝達される。そして回転軸２５が回転されることによりギア３４および３２と、ギア３５および３３を介して羽根車１３および凹形ローラ４４と羽根車１８及び凹形ローラ４５が回転せしめられることになる。駆動モータは紙幣の搬入時と搬出時とで回転方向が互いに反対となるように制御される。
【００１３】
収納部２には下部搬送壁５に連なって下方に向けて屈曲延長して形成された前壁面部５ａと、上部搬送壁４の筐体７の上端部に平行に延長された上壁面部４ａと、筐体７の後方に設けられた後壁面部４１とにより筐体７の下部に形成されている。収納部２内に設けた昇降可能なステージ３は、図示が省略されている昇降用モータにより昇降を制御され、収納部２内に収納された紙幣Ｐをここから搬出するときは、この昇降用モータによりステージ３を上昇させその上に積み重ねられた紙幣の最上面を搬送ローラ２７および２９に当接させるようにする。搬送路１から搬送されてくる紙幣Ｐを収納部２に搬入するときは、ステージ３を昇降モータにより下降させてステージ３上に積み重ねられた紙幣Ｐの上部に適当な収容空間を形成するようにする。また回転軸２６と２７との間には、ステージ３上に積み重ねられた紙幣の上面部を押えるための押え部材４２を回動自在に保持した軸４３が筐体７に支持されている。
【００１４】
さらに、上壁面部４ａにおいて、回転軸２６にＬ字形アーム４６、４７が回転自在に支持され、アーム４６、４７の下端部軸４８、４９に回転自在に設けられた押圧ローラ５０、５１がその外周面の一部を上部搬送壁４の開口部２２から下方へ露出するように設けられている。押圧ローラ５０、５１の外周面は、凹形ローラ４４、４５の外周面の凹部の底部に当接されるとともに、アーム４６、４７に設けられたコイルスプリング５２により凹形ローラ４４、４５側へ向けて付勢されている。
【００１５】
アーム４６、４７のそれぞれ筐体７に対峙する側面には、対をなすＬ字状のガイド部材５３、５４が各々設けられている。このガイド部材５３、５４の側方の内壁面５３ａ、５４ａは、収納部２の方向へ向かって傾斜され、凹形ローラ４４、４５と収納部２との間において、搬送路１の幅（内壁面５３ａ、５４ａとの間隔）が緩やかに狭くなるように構成している。搬送路１の幅が内壁面５３ａ、５４ａによって最も狭くなっている部分は搬送路１と収納部２との境界近傍としてある。
【００１６】
アーム４６、４７の上方部に設けられた軸５５は、連結板５６を介してソレノイド５７のプランジャ５８に取り付けられ、アーム４６、４７に取り付けられた押圧ローラ５０、５１およびガイド部材５３、５４の搬送路１からの退避機構を構成している。
【００１７】
次に、このように構成された従来の紙葉類収納装置の動作を説明する。
【００１８】
まず、紙幣の搬入動作を説明する。この時は、ソレノイド５７が消勢されるため、アーム４６、４７がコイルスプリング５２により、回転軸２６を中心にして図中反時計方向へ回転され、押圧ローラ５０、５１が凹形ローラ４４、４５の外周面の凹部の底部に圧接され、かつガイド部材５３、５４が搬送路１内に位置する状態となる。
【００１９】
図２１から図２３は、紙幣搬入の第１段階を示す。紙幣Pが搬送ローラ９と２４に挟まれて、収納部２の方向へ搬送されている途中で凹形ローラ４４、４５と押圧ローラ５０、５１の間を通過すると、凹形ローラ４４、４５の外周面両端の凸部によって紙幣Pがその幅方向に屈曲される。このとき紙幣はローラに圧接しながら屈曲させられ、かつ複数条の屈曲筋が付き、これによって紙幣Pにその搬送方向（長手方向）に強い腰（剛性）が付与される。さらに紙幣が収納部２の方向へ進んでいくと、紙幣Pの幅方向の両端部がガイド部材５３、５４の内壁面５３ａ、５４ａの傾斜に沿って上方へすくい上げられ、両端部分が上方へ屈曲されるように支持された状態で収納部２の上方の搬出入口へ進入する。
【００２０】
図２４および図２５は、紙幣Pが収納部２へさらに搬入された第２段階を示している。
【００２１】
これらの図に示すように、紙幣Pの後端が搬送ローラ９と搬送ローラ２４の間を通過した状態では、紙幣Pは、その先端近傍に押え部材４２の重みを受けるが、紙幣Pは凹形ローラ４４、４５と押圧ローラ５０、５１とによって付与された屈曲形状をガイド部材５３、５４によって安定に維持されており、かつ、紙幣Pは搬送方向に対して凹形ローラ４４、４５と押圧ローラ５０、５１およびガイド部材との２点間で支持されているため、紙幣Pが図中時計回り方向に回転するのを抑制される。これにより、紙幣Pの先端が折れ曲がることがないので、これが先に搬入された紙幣Ｐｓに衝突されることなく搬送姿勢を安定に保ったまま収納部の上方の搬出入口へ到達する。
【００２２】
このように凹形ローラ４４、４５と押圧ローラ５０、５１およびガイド部材５３、５４が搬送中の紙幣を幅方向に屈曲変形せせることで紙幣にその搬送方向に強い腰（剛性）を付与する手段を構成している。
【００２３】
紙幣Ｐの後端が羽根車１３、１８の位置に到達するまでは、羽根車の羽根１３ａ、１８ａは、紙幣Ｐの下面側に入り込んで変形しながら回転するので、紙幣がこの羽根車によって叩かれることはないが、図２６に示すように紙幣Ｐの後端が羽根車１３、１８の位置を抜けると、後続して搬入される紙幣の妨げとならないように紙幣Ｐの後端が羽根車１３、１８の羽根１３ａ、１８ａにより上方から下方に向かって叩き落とされ、先に搬入された紙幣Ｐｓ（紙幣がない場合はステージ３）の上に積み重ねられる。
【００２４】
次に紙幣の搬出動作について説明する。
【００２５】
収納部２内の紙幣Ｐをここから搬出する時は、ソレノイド５７を付勢してプランジャ５８を吸引する。これによりプランジャ５８が連結板５６を図中右方向に引っ張り、図２７、２８に示すように、アーム４６、４７がコイルスプリング５２の付勢力に抗して回転軸２６を中心に図中時計回り方向に回転される。この結果、アーム４６、４７に取り付けられた押圧ローラ５０、５１およびガイド部材５３、５４が上方に上がって搬送路１の外へ退避される。
【００２６】
押圧ローラ５０、５１およびガイド部材５３、５４が搬送路１内から退避されることにより、図２８に示すように搬送路１内には、紙幣Ｐの搬送時の抵抗となるものがなくなる。
【００２７】
次に、図示が省略されている昇降用モータにより、ステージ３を、この上に積み重ねられた紙幣Ｐとともに上昇させる。これにより、最上部の紙幣Ｐの上面が搬送ローラ２７、２９に当接される。ここで、搬送ローラ２７、２９を図中時計回り方向に回転させることにより、最上部の紙幣Ｐが収納部２より搬送路１側へ繰り出され、さらに搬送ローラ２１とゲートローラ１７、そして搬送ローラ２４と搬送ローラ９との間を通って搬送路１を介して外部へ搬出される。
【００２８】
【発明が解決しようとする課題】
しかしながら、このような従来の紙葉類収納装置においては、紙幣の搬入動作時に、収納部２へ搬入される紙幣Pの後端が羽根車１３、１８の位置を抜けるとガイド部材５３、５４により維持されていた屈曲形状が解消されるため、紙幣Pに付与された屈強な腰（剛性）が消失する。また、図５１に示すように押え部材４２により紙幣Pの先端部を下方へ上向かって押し、羽根車の羽根１３ａ、１８ａで紙幣Pの後端部を叩き落す時、紙幣Pの搬送方向の屈強な腰が消失しているため紙幣がその中央部を頂点にして両側へ折れ曲がり凸状に変形する場合がある。この状態で次の紙幣が搬入された場合、紙幣にジャミングが発生しやすく、また、紙幣を収納部のステージ３上に平坦な正常な状態に積み重ねることができなくなる。そして、収納部に搬入した紙幣を平坦に積み重ねることができないとここから紙幣を搬出するときも紙幣が搬出の途中でジャミングを起こし搬送路１内に詰まって搬出できなくなる事態が生じる。
【００２９】
この発明は、このような不都合を解消するために、紙幣を収納装置へ搬入および搬出するときに紙幣にジャミングが発生することなく紙幣の搬入および搬出を円滑に行える紙葉類収納装置を提供することを課題とするものである。
【００３０】
【課題を解決するための手段】
上記の課題を達成するために、請求項１の発明は、紙葉類が搬送される搬送路の一端に設けられこの搬送路から搬入される紙葉類を積み重ねて収納する紙葉類収納部と、前記搬送路において前記紙葉類を搬送する搬送ローラと、前記紙葉類収納部の近傍に前記搬送ローラと隣接して設けられ前記紙葉類の搬送方向の後端を下方へ押し下げる弾性体からなる羽根を有する回転羽根車と、前記紙葉類収納部の上方の紙葉類搬出入口に揺動自在に支持され搬入された紙葉類の搬送方向の先端付近を下方に押し下げる押え部材と、前記搬送路の紙葉類収納部近傍に前記搬送路を搬送される紙葉類をその幅方向に規制して搬送方向と直交する方向に屈曲させて紙葉類の搬送方向の剛性を高める剛性付与手段と、前記紙葉類搬出入口に、搬送方向に前記剛性付与手段と間隔をおいてその幅方向寸法が紙葉類の幅より小さくなるように突出され、前記紙葉類搬出入口に搬入された紙葉類が、その後端が前記剛性付与手段を通過する前にその幅方向の両端部分を支持され、その上方への屈曲を維持する1対の屈曲補助部材とを設けてなる紙葉類収納装置において、前記紙葉類収納部の上方に、ゲートローラと外周の一部に摩擦材を有する搬送ローラとで構成され、前記紙葉類収納部に積み重ねられた紙葉類を 1 枚ずつ分離して前記搬送路に搬出する搬出手段を設けるとともに、前記紙葉類収納部内にこの中の積み重ねられた紙葉類を昇降自在に支持し前記繰出し手段に接離させるステージ機構を設け、さらに前記紙葉類収納部に積層された紙葉類を搬出するとき、前記屈曲補助部材を紙葉類の搬出を阻害しない位置に退避させる屈曲補助部材退避手段を設けてなることを特徴とするものである。
【００３１】
請求項２の発明は、前記の屈曲補助部材は、紙葉類収納部の搬送方向の中央部付近に設けるものである。
【００３２】
請求項３の発明は、前記屈曲補助部材退避手段が、上下方向に摺動自在に支持された屈曲補助部材と、この屈曲補助部材を下方向に付勢する付勢手段とで構成され、前記紙葉類収納部に積層された紙葉類を搬送路へ搬出するときに前記ステージにより押し上げられる紙葉類の上面で前記屈曲補助部材を前記付勢手段の付勢力に抗して上方に退避させるように構成したものである。
【００３３】
【発明の実施の形態】
以下、この発明の実施の形態を図面を参照して詳細に説明する。なお、従来の紙葉類収納装置と同一の構成要素については同一の符号を付してしてその詳細な説明を省略し、主としてこの発明の特徴的部分について説明する。
【００３４】
図１はこの発明の実施例による紙葉類収納装置の側面断面図、図２は図１のａ−ａ矢視の断面図、図３は図１のｂ−ｂ矢視の断面図、図４は図１のｃ−ｃ矢視の断面図、図５はｅ−ｅ矢視の断面図である。なお図１は図３のｄ−ｄ矢視の断面図である。
【００３５】
搬送路１は紙葉類を走行させるための所定の空間をおいて互いに平行に相対して配置され、筐体７に支持された上部搬送壁４と下部搬送壁５とによって形成されている。
【００３６】
下部搬送壁５に設けられている開口部６、６からは、両端が筐体７に回転可能に支持された回転軸８に設けられた搬送ローラ９、９の外周部の一部が下部搬送壁５から搬送路１内に露出している。また、この開口部６より下流側の開口部１０、１１および１２からは、両端部が筐体７に回転可能に支持された回転軸１５に設けられた羽根車１３と外周面が凹状に形成された凹形ローラ４４、両端部が下部搬送壁５に支持された軸１６に回転可能に設けられたゲートローラ１７および両端部が筐体７に回転可能に支持された回転軸２０に設けられた根車１８と外周面が凹状に形成された凹形ローラ４５がそれぞれ露出されている。
【００３７】
羽根車１３、１８は弾性材料からなる複数枚の羽根１３ａ、１８ａを心棒に等間隔で放射状に取り付けた構成となっている。
【００３８】
上部搬送壁４の側において、両端部を筐体７に回転自在に支持された回転軸２３、２５、２６および２８にそれぞれ設けられた搬送ローラ２４、２１、２７および２９が、それぞれの外周部の一部を上部搬送壁の開口からから搬送路１内へ露出するように配置されている。搬送ローラ２１、２７、２９のそれぞれの外周部には所定の円周角だけ摩擦部材２１ａ、２７ａ、２９ａが設けられている。これらの摩擦部材２１ａ、２７ａ、２９ａは、紙幣Ｐを間欠的に搬送するために設けられている。
【００３９】
搬送路１内の上下の対となるローラ、すなわち搬送ローラ２４、２４と搬送ローラ６、６および搬送ローラ２１とゲートローラ１７は互いに接触して回転し、紙幣を間に挟んで搬送する。
【００４０】
また、回転軸２６にＬ字形のアーム４６、４７が回転自在に支持され、アーム４６、４７の下端部軸４８、４９に回転自在に設けられた押圧ローラ５０、５１がその外周面の一部を上部搬送壁４の開口部２２から搬送路１へ露出するように設けられている。押圧ローラ５０、５１の外周面は、凹形ローラ４４、４５の外周面の凹部の底部に当接されるとともに、アーム４６、４７に設けられたコイルスプリング５２により凹形ローラ４４、４５側へ向けて付勢されている。
【００４１】
アーム４６、４７のそれぞれ筐体７に対峙する側面には、対をなすＬ字状のガイド部材５３、５４が各々設けられている。このガイド部材５３、５４の側方の内壁面５３ａ、５４ａは、収納部２への搬送方向に向かって傾斜され、凹形ローラ４４、４５と収納部２との間において、搬送路１の幅（内壁面５３ａ、５４ａとの間隔）が緩やかに狭くなるように構成している。搬送路１の幅が内壁面５３ａ、５４ａによって最も狭くなっている部分は搬送路１と収納部２との境界近傍としてある。
【００４２】
アーム４６、４７の上方部に設けられた軸５５は、連結板５６を介してソレノイド５７のプランジャ５８に取り付けられ、アーム４６、４７に取り付けられた押圧ローラ５０、５１およびガイド部材５３、５４の搬送路１からの退避機構を構成している。
【００４３】
収納部2には、さらに昇降可能なステージ3と、ステージ3上に積み重ねられた紙幣を上方から押えるための押え部材４２が設けられている。
【００４４】
ここまでは、従来の紙葉類収納装置と同じであるが、さらにこの発明にしたがって、収納部２の上部の両側の筐体7に固定された支持部材１０１、１０２に、紙幣の屈曲を助けるための屈曲補助部材１０３、１０４が上下方向に摺動可能に支持されている。この屈曲補助部材１０３、１０４は常時支持部材１０１、１０２内に内装されたばね１０５、１０６よって下方に押し下げられており、そのストッパ部１０３ａ、１０４ａが支持部材１０１、１０２の下端に係止されて収納部内での摺動範囲が制限されている。その際、屈曲補助部材１０３、１０４の先端部は搬入されてくる紙幣の高さが上下に増減しても紙幣の両側を支持できるように収納部２内の上壁面部４aの下まで入り込ませている。また、この屈曲補助部材１０３、１０４は搬送路１の幅方向に突出し、その間隔は、搬入される紙幣の幅より狭い寸法となっている。なお、この実施例においては、屈曲補助部材１０３、１０４が、紙幣の両側を搬送方向の中央部付近で支持する形状となっているが、これを搬送方向に長く支持する形状にしてもよい。しかし、この屈曲補助部材の支持分部が長くなると紙幣の姿勢は安定するが、紙幣を落とし込む際に抵抗となるため、支持部の長さは、両者の兼合いで決めるのがよい。
【００４５】
次に、このように構成されたこの発明の実施例の紙葉類収納装置の紙幣の搬入動作について説明する。
【００４６】
図６〜図８は紙幣の搬入過程の第１段階である。上下の搬送ローラ６、６および２４、２４に挟まれて搬送路１の左側の入口から右側の収納部２の方向へ搬送されている紙幣Ｐが凹形ローラ４４、４５と押圧ローラ５０、５１との間を通過するとき、凹形ローラ４４、４５の外周面両端の凸部によりこの紙幣Pはその幅方向に屈曲される。このとき、紙幣Ｐは凹形ローラ４４、４５と押圧ローラ５０、５１とによって挟持された状態で屈曲させられ、かつ複数条の屈曲筋が付くため、紙幣Ｐの搬送方向に屈強な腰（剛性）が付与され、その搬送方向には折れ曲がることなく真直ぐに伸長する。
【００４７】
紙幣Ｐがさらに収納部２の方向へ進むと、紙幣の幅方向の両端部が傾斜したガイド部材５３、５４の内壁面５３ａ、５４ａによってさらにすくい上げられて、紙幣は、断面がほぼU字状に屈曲された状態となり、そのままの姿勢で支持されて収納部２の上方へ進入する。
【００４８】
紙幣Pがさらに進行し、その先端が収納部２の上方の搬送通路内に突出した屈曲補助部材１０３、１０4の位置を通過し、その後端が搬送ローラ６、６および２４、２４の間を通過した図９〜図１１に示すような第２段階の状態においては、紙幣Pは、その先端部近傍に押え部材４２の重みを受けるが、紙幣Pは凹形ローラ４４、４５と押圧ローラ５０、５１で挟持されるとともにガイド部材５３、５４によって支持され、かつ、紙幣Pの幅より狭い間隔にされた屈曲補助部材１０３、１０４によって紙幣Pの幅方向の両端部が支持されるので、紙幣のU字状の屈曲姿勢がそのまま維持され、紙幣Pが図中時計回り方向に回転するのが抑制される。これにより、紙幣Pの先端が収納部２の後壁面部４１に到達する直前まで紙幣Pの先端を搬送路１を水平に延ばした延長線上より上方の位置に保つことができるため、紙幣Ｐは、収納部２内に先に搬入された紙幣Pｓと衝突することなく安定な搬送姿勢のままで収納部２の上方へ到達する。
【００４９】
なお、屈曲補助部材１０３、１０４は、収納部２の上方の搬送路内にその幅方向の両側から突出し、搬送路の幅を狭めているが、紙幣Ｐの先端がここを通過するときは、紙幣Ｐはガイド部材５３、５４を通過するときにこれによりすくい上げられながら、Ｕ字状に屈曲されているため、紙幣Ｐが全体として先端の幅を狭めた状態で先端を斜め上方に向けながら搬入されるので、紙幣Ｐの先端が、仮にほぼ屈曲補助部材１０３、１０４の設けられた高さの位置まで下がった状態で搬入されたとしても、紙幣Ｐの搬入が屈曲補助部材１０１３、１０４によって阻害されることなく円滑に行われる。
【００５０】
さらに紙幣Pが搬送されと、図１２〜図１３に示すように第３段階となる。
【００５１】
この段階においては、紙幣Pの後端が羽根車１３、１８の位置を抜けたところで、後続して搬入される紙幣の妨げとならないように紙幣Pの後端が羽根車の羽根によって下方に向かって叩き落とされる。これによって紙幣Ｐの後端の支持がなくなるため、紙幣Ｐの先端は、これまで紙幣自身によって持ち上げていた押え部材４２の自重によって図中時計方向に回転させられ、紙幣Ｐが収納部２内へ落下される。このとき、屈曲補助部材１０３、１０４によって、ガイド部材５３、５４等によって付与されていた紙幣Ｐの屈曲形状を、この紙幣Ｐが前記ガイド部材５３、５４を抜けた後においても維持することができるため、屈曲補助部材の設けられた紙幣Ｐの中央部付近に屈強な腰が維持される。この結果、紙幣Ｐを断面Ｕ字状の屈曲状態に保ったまま、ほぼ水平の安定した姿勢で収納部２内へ落とし込むことができる。
【００５２】
このように、この発明の装置では、紙幣Ｐが収納部２の上方からこの中に落とし込まれるとき、紙幣Ｐはその中央部付近を境にして前後端側が下方に屈曲され、凸状に変形されるようなことがないので、最後に、図１４（第４段階）に示すように、先に搬入された紙幣Pｓ（紙幣がない場合はステージ３）の上に載せられる時、ジャミングすることなく水平に延ばされた状態で整列して積み重ねられる。
【００５３】
次に、収納部２に収納された紙幣を搬送路１へ搬出するときの搬出動作を説明する。
【００５４】
図１５および図１６に示すように、紙幣の搬出を行うときは、退避機構のソレノイド５７を付勢しプランジャ５８を吸引して、搬出モードとする。これによりアーム４６、４７の上端が連結板５６を介してコイルスプリング５２に抗して図中時計方向に回動され、アームの下端側の押圧ローラ５０、５１およびガイド部材５３、５４が、搬送路１の上方へ退避される。
【００５５】
そして、図示が省略されている昇降用モータにより紙幣の積み重ねられたステージ３を上昇させると、ステージ３および紙幣Pが押え部材４２を載置したまま上昇する。この上昇により、屈曲補助部材１０３および１０４は、紙幣の幅より狭い間隔でかつ上下方向に摺動自在に設けられているので、その下端にステージ３上の最上部の紙幣が当接し、紙幣とともにばね１０３ａ、１０４ａの付勢力に抗して押し上げられ、最上部の紙幣が搬送ローラ２７および２９の外周面に当接する。この後、従来装置と同様に搬送ローラ２９、２７、２１、および２４を同期して搬入時とは反対の時計方向に回転させることにより収納部２内に積みかねられた紙幣を上部から１枚ずつ搬送ローラ２９および２７の摩擦部材２９aおよび２７aの外周面で搬送路１側へ繰り出すことができる。搬送路１内へ送られた紙幣は、それぞれゲートローラ１７と搬送ローラ２１、および搬送ローラ２４と９に挟まれて搬送路１の左端の入口側へ搬送される。
【００５６】
このように、収納部２の上部の搬送路上に紙幣の屈曲を助けるために設けられている屈曲補助部材１０１、１０２は、紙幣の搬入動作時には紙幣の屈曲を与える抵抗体となるが、搬出動作時には搬送路から自動的に退避され、紙幣の搬出には何らの影響も与えない。
【００５７】
なお、上記の実施例においては、屈曲補助部材を退避するための機構として、屈曲補助部材を上下方向に摺動自在に支持してばねにより下方へ付勢する機構を示したが、この発明では、これに限定さされるものではない。この屈曲部材退避機構は、屈曲補助部材を紙幣の搬入動作時には搬送路内へ突出させ、搬出動作時には、搬送路の外側へ退避させるものであるから、例えば電磁的駆動機構により屈曲補助部材を上下方向あるいは水平方向に変位させて搬送路内へ出没させるようにした機構を使用することもできる。

【発明の効果】
以上説明したように、紙葉類が搬送される搬送路の一端に設けられこの搬送路から搬入される紙葉類を積み重ねて収納する紙葉類収納部と、前記搬送路において前記紙葉類を搬送する搬送ローラと、前記紙葉類収納部の近傍に前記搬送ローラと隣接して設けられ前記紙葉類の搬送方向の後端を下方へ押し下げる弾性体からなる羽根を有する回転羽根車と、前記紙葉類収納部の上方の紙葉類搬出入口に揺動自在に支持され搬入された紙葉類の搬送方向の先端付近を下方に押し下げる押え部材と、前記搬送路の紙葉類収納部近傍に前記搬送路を搬送される紙葉類をその幅方向に規制して搬送方向と直交する方向に屈曲させて紙葉類の搬送方向の剛性を高める剛性付与手段と、前記紙葉類搬出入口に、搬送方向に前記剛性付与手段と間隔をおいてその幅方向寸法が紙葉類の幅より小さくなるように突出され、前記紙葉類搬出入口に搬入された紙葉類が、その後端が前記剛性付与手段を通過する前にその幅方向の両端部分を支持され、その上方への屈曲を維持する 1 対の屈曲補助部材とを紙葉類収納装置において、前記紙葉類収納部の上方に、ゲートローラと外周の一部に摩擦材を有する搬送ローラとで構成され、前記紙葉類収納部に積み重ねられた紙葉類を 1 枚ずつ分離して前記搬送路に搬出する搬出手段を設けるとともに、前記紙葉類収納部内にこの中の積み重ねられた紙葉類を昇降自在に支持し前記繰出し手段に接離させるステージ機構を設け、さらに前記紙葉類収納部に積層された紙葉類を搬出するとき、前記屈曲補助部材を紙葉類の搬出を阻害しない位置に退避させる屈曲補助部材退避手段を設けた構成としているので、紙葉類の後端が搬送路の搬送ローラから離れて収納部の上部に送られた状態においても、紙葉類は、幅方向に屈曲された状態を保つので、その搬送方向に真直ぐに伸びた姿勢のまま搬送路から収納部へ落し込まれるようになり、したがって、紙葉類が収納部へ落下するときにその搬送方向に屈曲して収納部内のステージ上に積み重ねられることがなくなり、紙葉類が収納部内でのジャミングの発生を防止できる。
【００５９】
このように、この発明によれば、紙葉類を収納部に搬入、搬出する時、紙葉類のジャミングの発生のない紙葉類収納装置を得ることができる。

[0017]
Next, the operation of the conventional paper sheet storage device configured as described above will be described.
[0018]
First, the bill carry-in operation will be described. At this time, since the solenoid 57 is de-energized, the arms 46 and 47 are rotated by the coil spring 52 around the rotation shaft 26 in the counterclockwise direction in the figure, and the pressing rollers 50 and 51 are moved to the concave rollers 44 and 44, respectively. In this state, the guide members 53 and 54 are in pressure contact with the bottom of the concave portion of the outer peripheral surface 45 and located in the transport path 1.
[0019]
FIG. 21 to FIG. 23 show the first stage of banknote carry-in. When the banknote P passes between the concave rollers 44 and 45 and the pressing rollers 50 and 51 while being transported in the direction of the storage unit 2 between the transport rollers 9 and 24, the concave rollers 44 and 45 The bill P is bent in the width direction by the convex portions at both ends of the outer peripheral surface. At this time, the banknote is bent while being pressed against the roller, and a plurality of bending lines are attached, whereby the banknote P is given a strong waist (rigidity) in its transport direction (longitudinal direction). As the bill further advances toward the storage unit 2, both end portions in the width direction of the bill P are scooped upward along the inclination of the inner wall surfaces 53a and 54a of the guide members 53 and 54, and both end portions are bent upward. In a state where it is supported as described above, it enters the carry-in / out entrance above the storage unit 2.
[0020]
24 and 25 show a second stage in which the banknote P is further carried into the storage unit 2.
[0021]
  As shown in these drawings, in a state where the rear end of the banknote P passes between the transport roller 9 and the transport roller 24, the banknote P receives the weight of the pressing member 42 in the vicinity of the front end, but the banknote P is recessed. The bent shape provided by the forming rollers 44 and 45 and the pressing rollers 50 and 51 is stably maintained by the guide members 53 and 54, and the bill P is pressed by the concave rollers 44 and 45 in the transport direction. Since it supports between two points with the rollers 50 and 51 and a guide member, it is suppressed that the banknote P rotates clockwise in the figure. As a result, the leading edge of the banknote P is not bent, so that it may collide with the banknote Ps carried in first.WhenAbove the storage section while maintaining a stable transport postureofReach the carry-in / out entrance.
[0022]
  Thus, the concave rollers 44 and 45, the pressing rollers 50 and 51, and the guide member53, 54 constitutes a means for giving the banknote a strong waist (rigidity) in the transport direction by bending and deforming the banknote being transported in the width direction.
[0023]
Until the rear end of the banknote P reaches the position of the impellers 13 and 18, the blades 13 a and 18 a of the impeller enter the lower surface side of the banknote P and rotate while being deformed. However, as shown in FIG. 26, when the rear end of the banknote P passes through the positions of the impellers 13 and 18, the rear end of the banknote P is not impeded by the banknotes subsequently carried in. The blades 13a and 18a of 13 and 18 are struck down from the upper side to the lower side, and are stacked on the banknote Ps (stage 3 when there is no banknote) carried in first.
[0024]
Next, the banknote carry-out operation will be described.
[0025]
When the banknote P in the storage unit 2 is carried out from here, the solenoid 57 is energized to suck the plunger 58. As a result, the plunger 58 pulls the connecting plate 56 in the right direction in the figure, and the arms 46 and 47 counteract the urging force of the coil spring 52 in the clockwise direction in the figure as shown in FIGS. Rotated in the direction. As a result, the pressing rollers 50 and 51 and the guide members 53 and 54 attached to the arms 46 and 47 are moved upward and retracted out of the conveyance path 1.
[0026]
When the pressing rollers 50 and 51 and the guide members 53 and 54 are retracted from the inside of the transport path 1, as shown in FIG.
[0027]
Next, the stage 3 is raised together with the banknotes P stacked thereon by an elevating motor (not shown). Thereby, the upper surface of the uppermost banknote P is brought into contact with the transport rollers 27 and 29. Here, by rotating the transport rollers 27 and 29 in the clockwise direction in the drawing, the uppermost banknote P is fed out from the storage unit 2 toward the transport path 1, and further, the transport roller 21, the gate roller 17, and the transport roller 24 and the conveyance roller 9, and are carried outside through the conveyance path 1.
[0028]
[Problems to be solved by the invention]
However, in such a conventional paper sheet storage device, when the rear end of the banknote P carried into the storage unit 2 passes through the position of the impellers 13 and 18 during the banknote carrying-in operation, the guide members 53 and 54 Since the bent shape that has been maintained is eliminated, the strong waist (rigidity) imparted to the banknote P disappears. Further, as shown in FIG. 51, when the leading end of the bill P is pushed upward by the pressing member 42 and the trailing end of the bill P is knocked down by the blades 13a and 18a of the impeller, Since the strong waist has disappeared, the banknote may be bent to both sides with its central portion at the top and deformed into a convex shape. When the next banknote is carried in this state, jamming is likely to occur in the banknote, and the banknote cannot be stacked in a flat normal state on the stage 3 of the storage unit. And if the banknotes carried into the storage unit cannot be stacked flatly, even when the banknotes are unloaded from the storage section, the banknotes jam in the middle of unloading and become jammed in the transport path 1 and cannot be unloaded.
[0029]
In order to eliminate such inconveniences, the present invention provides a paper sheet storage apparatus that can smoothly carry in and out banknotes without causing jamming of the banknotes when the banknotes are carried into and out of the storage apparatus. This is a problem.

The bending assisting members 103 and 104 are always pushed downward by springs 105 and 106 built in the support members 101 and 102, and the stopper portions 103a and 104a are locked to the lower ends of the support members 101 and 102 and stored. The sliding range within the part is limited. At that time, the leading end portions of the bending assisting members 103 and 104 are inserted below the upper wall surface portion 4a in the storage portion 2 so that both sides of the bill can be supported even if the height of the bill to be carried in is increased or decreased. ing. Further, the bending assisting members 103 and 104 protrude in the width direction of the transport path 1, and the distance between them is smaller than the width of the bills to be carried. In this embodiment, the bending assisting members 103 and 104 have a shape that supports both sides of the bill in the vicinity of the central portion in the transport direction. However, when the supporting portion of the bending assisting member becomes longer, the posture of the banknote is stabilized, but resistance is provided when the banknote is dropped, so the length of the supporting portion is preferably determined by the balance between the two.
[0045]
Next, the banknote carrying-in operation of the paper sheet storage apparatus of the embodiment of the present invention configured as described above will be described.
[0046]
6-8 is the 1st step of the carrying-in process of a banknote. The banknotes P sandwiched between the upper and lower transport rollers 6, 6 and 24, 24 and transported from the left entrance of the transport path 1 toward the right storage unit 2 are recessed rollers 44, 45 and pressing rollers 50, 51. The bill P is bent in the width direction by the convex portions at both ends of the outer peripheral surfaces of the concave rollers 44 and 45. At this time, the banknote P is bent in a state of being sandwiched between the concave rollers 44 and 45 and the pressing rollers 50 and 51 and has a plurality of bending lines, so that the banknote P has a strong waist (rigidity). ) And is extended straight without bending in the transport direction.
[0047]
When the bill P further advances in the direction of the storage unit 2, both ends of the bill in the width direction are further scooped up by the inner wall surfaces 53 a and 54 a of the inclined guide members 53 and 54, and the bill has a substantially U-shaped cross section. It will be in the bent state, will be supported with the posture as it is, and will enter above the storage part 2.
[0048]
The bill P further advances, and the leading end thereof passes through the position of the bending assisting member 103, 10 4 protruding into the conveying path above the storage portion 2, and the trailing end passes between the conveying rollers 6, 6, 24, and 24. In the state of the second stage as shown in FIGS. 9 to 11, the banknote P receives the weight of the pressing member 42 in the vicinity of the front end portion thereof, but the banknote P has the concave rollers 44 and 45 and the pressing roller 50, Since both ends in the width direction of the bill P are supported by the bending auxiliary members 103 and 104 which are sandwiched by 51 and supported by the guide members 53 and 54 and spaced at a distance narrower than the width of the bill P, The U-shaped bending posture is maintained as it is, and the bill P is prevented from rotating in the clockwise direction in the figure. Thereby, since the front-end | tip of banknote P can be kept in the position above the extended line which extended the conveyance path 1 horizontally just before the front-end | tip of the banknote P arrives at the rear wall part 41 of the accommodating part 2, the banknote P is The upper part of the storage unit 2 is reached in a stable conveying posture without colliding with the banknote Ps previously carried into the storage unit 2.
[0049]
Note that the bending assisting members 103 and 104 protrude from both sides in the width direction into the transport path above the storage unit 2 and narrow the width of the transport path, but when the tip of the banknote P passes here, The bill P is bent in a U-shape while being scooped up when passing through the guide members 53 and 54, so that the bill P is carried in while the tip is inclined obliquely upward with the tip width narrowed as a whole. Therefore, even if the leading edge of the banknote P is carried in a state where the leading edge of the banknote P is substantially lowered to the position where the bending auxiliary members 103 and 104 are provided, the loading of the banknote P is obstructed by the bending auxiliary members 1013 and 104. Is done smoothly.
[0050]
When the banknote P is further conveyed, the third stage is performed as shown in FIGS.
[0051]
At this stage, when the rear end of the banknote P passes through the positions of the impellers 13 and 18, the rear end of the banknote P is directed downward by the blades of the impeller so as not to interfere with the banknotes subsequently carried in. And knocked down. As a result, the rear end of the banknote P is not supported, so that the front end of the banknote P is rotated in the clockwise direction in the figure by the weight of the presser member 42 that has been lifted by the banknote itself, and the banknote P is moved into the storage unit 2. Be dropped. At this time, the bending shape of the banknote P provided by the guide members 53 and 54 and the like can be maintained by the bending auxiliary members 103 and 104 even after the banknote P passes through the guide members 53 and 54. Therefore, a strong waist is maintained near the central portion of the banknote P provided with the bending assisting member. As a result, the banknote P can be dropped into the storage unit 2 in a substantially horizontal stable posture while keeping the bent state with a U-shaped cross section.
[0052]
As described above, in the apparatus of the present invention, when the banknote P is dropped into the storage unit 2 from above, the banknote P is bent downward at the front and rear end sides around the central part thereof, and deformed into a convex shape. Finally, as shown in FIG. 14 (fourth stage), jamming when placed on the previously loaded banknote Ps (stage 3 if there is no banknote) Instead, they are stacked in a horizontally extended state.
[0053]
Next, the carry-out operation when carrying out the banknotes stored in the storage unit 2 to the transport path 1 will be described.
[0054]
As shown in FIG. 15 and FIG. 16, when carrying out banknotes, the solenoid 57 of the retracting mechanism is urged and the plunger 58 is sucked to enter the carry-out mode. As a result, the upper ends of the arms 46 and 47 are rotated clockwise in the drawing against the coil spring 52 via the connecting plate 56, and the pressing rollers 50 and 51 and the guide members 53 and 54 on the lower end side of the arm are conveyed. It is retreated above the road 1.
[0055]
And if the stage 3 on which the banknote was piled up is raised by the raising / lowering motor which illustration is abbreviate | omitted, the stage 3 and the banknote P will raise, with the pressing member 42 mounted. Because of this rise, the bending assisting members 103 and 104 are provided so as to be slidable in the vertical direction with a narrower interval than the width of the banknote. The bills are pushed up against the urging force of the springs 103 a and 104 a, and the uppermost banknote comes into contact with the outer peripheral surfaces of the transport rollers 27 and 29. Thereafter, the banknotes stacked in the storage portion 2 by rotating the transport rollers 29, 27, 21, and 24 in a clockwise direction opposite to that at the time of carry-in in the same manner as in the conventional apparatus from the top. It can feed to the conveyance path 1 side by the outer peripheral surface of the friction members 29a and 27a of the conveyance rollers 29 and 27 one by one. The banknotes sent into the conveyance path 1 are respectively sandwiched between the gate roller 17 and the conveyance roller 21 and the conveyance rollers 24 and 9 and conveyed to the entrance end on the left end of the conveyance path 1.
[0056]
As described above, the bending auxiliary members 101 and 102 provided to assist the bending of the banknotes on the conveyance path on the upper part of the storage unit 2 serve as resistors that give the banknotes to be bent during the banknote loading operation. Sometimes it is automatically retracted from the transport path and has no effect on the banknotes being carried out.
[0057]
In the above embodiment, as a mechanism for retracting the bending assisting member, a mechanism for supporting the bending assisting member slidably in the vertical direction and biasing it downward by a spring is shown. However, the present invention is not limited to this. This bending member retracting mechanism projects the bending auxiliary member into the conveyance path during the bill loading operation, and retracts the bending auxiliary member up and down by the electromagnetic drive mechanism. It is also possible to use a mechanism that is displaced in the horizontal direction or the horizontal direction so as to appear in and out of the conveyance path.
[0058]
