【発明の属する技術分野】
本発明は、紙葉類処理機の紙葉類保留装置に係り、特に、一枚ずつ送り込まれる紙葉類を受け入れて集積状態で一時保留する保留室を備え、その保留室の下部底を開閉部材により構成し、開閉部材の閉塞状態において該開閉部材上に紙葉類を保持し集積状態で保留室内に一時保留するとともに、この集積状態で一時保留した紙葉類群を開閉部材の開放によって落下させ保留室下方の収納室へ収納せしめる紙葉類処理機の紙葉類保留装置に関する。
【０００２】
【従来の技術】
一枚ずつ送り込まれる紙葉類を受け入れて集積状態で一時保留する保留室を備えた紙葉類処理機の紙葉類保留装置として、例えば特公平３−３３６１６号公報に示されているように、保留室の下部底を開閉部材によって構成し、この開閉部材の閉塞状態において該開閉部材上に紙葉類を保持し集積状態で保留室内に一時保留するとともに、この集積状態で一時保留した紙葉類群を開閉部材の開放によって落下させ保留室下方の収納室へ収納せしめるようにしたものが従来から知られている。
【０００３】
上記従来の装置の開閉部材は、各々が支軸を中心に左右対称に揺動する一対の可動板からなり、その一対の可動板が水平姿勢にある時に紙葉類を保持し、垂直姿勢に開くことによって紙葉類を一括して収納部へ落下させるよう構成されたものである。
【０００４】
【発明が解決しようとする課題】
上述の従来の紙葉類処理機の紙葉類保留装置は、一対の可動板が揺動して水平姿勢および垂直姿勢をとることにより、一枚ずつ送り込まれる紙葉類を受け入れて一時保留し、また、収納部へ落下させるが、その保留室へ一枚ずつ送り込まれて保持される時の可動板上の紙葉類群は、その紙葉類群の最下面の位置が一定であるため、一時保留の設定枚数が多い場合には送り込み位置との差が大きく、そのため、送り込み枚数が少ない段階では、落下高さが大きくて、送り込まれる紙葉類が立位状態となって後端部が浮き上がったような格好で落下し、その浮き上がった後端部に次に送り込まれる紙葉類の先端がぶつかって、ジャムが発生する。
【０００５】
また、ジャムが発生しないよう、紙葉類の送り込み枚数に応じて上記可動板を水平姿勢のまま上下に平行移動させることも考えられるが、そのように開閉部材を平行移動させ、かつ、最下点で開閉部材を開放させるようにするためには機構が複雑にならざるを得ず、コストが高くつく。また、ジャムを防ぐために上記一対の可動板を上向き姿勢にし、紙葉類の送り込み枚数に応じて水平姿勢に近づけるようにすることも考えられるが、そのように上記可動板を上向き姿勢にするだけでは、集積状態の紙葉類群は最下面の中央域を支持できても、左右の端部域の下方に隙間ができ、そのため、集積紙葉類群が傾いて、やはりジャムが発生する。
【０００６】
したがって、保留室の下部底を開閉部材によって構成する紙葉類処理機の紙葉類保留装置においてジャム発生を防止し、かつ、機構の簡易化とコストダウンを実現することが課題である。本発明はこの課題を解決することを目的とする。
【０００７】
【課題を解決するための手段】
本発明の紙葉類処理機の紙葉類保留装置は、一枚ずつ送り込まれる紙葉類を受け入れて集積状態で一時保留する保留室を備え、前記保留室の下部底を開閉部材により構成し、その開閉部材の閉塞状態において開閉部材上に紙葉類を保持し集積状態で保留室内に一時保留するとともに、集積状態で一時保留した紙葉類群を開閉部材の開放によって落下させ保留室下方の収納室へ収納せしめるものであって、開閉部材として、一対の揺動部材と、一対の第１支持部材と、一対の第２支持部材を具備し、また、一対の揺動部材を揺動させる駆動機構を具備するものとし、一対の揺動部材は、保留室下部の左右側方に水平方向に並ぶ各支軸を中心に左右対称に所定角度揺動し、各々が全体として上向きで各先端が両支軸間の内側上方で向き合う上向き姿勢と、各々が全体として水平で両支軸間の内側に位置する水平姿勢と、各々が全体として下向きの下向き姿勢をとるよう構成し、一対の第１支持部材は、一対の揺動部材の各先端にこれら一対の揺動部材の揺動範囲において相互に干渉しない配置で設けられ、一対の揺動部材が上向き姿勢にある時に保留室内の集積状態の紙葉類群の最下面の中央域を支持するよう構成し、一対の第２支持部材は、一対の揺動部材または一対の第１支持部材に対し一対の揺動部材の上向き姿勢から水平姿勢への揺動範囲においては相互に干渉しないとともに一対の第１支持部材と干渉しない配置で支持軸を中心に揺動可能に設けられ、一対の揺動部材が上向き姿勢から水平姿勢の間にある時に保留室内の集積状態の紙葉類群の最下面の左右の端部域を支持するよう構成したものである。
【０００８】
ここで、第２支持部材は、重錘を有し、この重錘により、一対の揺動部材が上向き姿勢から水平姿勢の間にある時に保留室内の集積状態の紙葉類群を支持する姿勢を保つとともに、一対の揺動部材が下向き姿勢をとる時にこれら一対の揺動部材と一体的に移動する姿勢を保つ構成のものとするのがよい。
【０００９】
このように構成された紙葉類処理機の紙葉類保留装置に一枚ずつ送り込まれる紙葉類は、保留室の下部底を構成する開閉部材の閉塞状態において該開閉部材により保持されて集積状態で保留室内に一時保留される。また、この保留室内に集積状態で一時保留された紙葉類は、開閉部材が開放されることによって落下し、収納室に収納される。そして、その開閉部材は、一枚ずつ送り込まれる紙葉類を受け入れて保持し集積状態で保留室内に一時保留する時に、一対の揺動部材が各支軸間の内側上方で各先端が向き合う上向き姿勢となり、一対の第１支持部材が上方に持ち上がった位置において集積紙葉類群の最下面の中央域を支持するとともに、その集積紙葉類群の左右の端部域を一対の第２支持部材が支持する。その際、集積紙葉類群は一対の第１支持部材と一対の第２支持部材により持ち上げ位置に支持されるため、一時保留の設定枚数が多い場合でも紙葉類群の最上面と送り込み位置との落差は小さくなり、その落差は、一対の揺動部材が紙葉類の送り込み枚数に応じて水平姿勢に向け揺動することにより常に小さく保たれる。したがって、ジャムの発生はなくて、紙葉類はスムーズに受け入れられて集積保持される。
【００１０】
保留室の下部底を構成する上記開閉部材は、第１の揺動部材の揺動によって集積紙葉類群の支持位置の上下移動と開放の両方を行うものであり、支持位置の上下移動と開放を同一の駆動機構で行うため、コストダウンと構造の簡略化が可能である。
【００１１】
なお、上の記載中、「左右」は、全体としての機械の左右と一致するものに限定されるものではない。また、請求項の記載中の「左右」も同様に機械の左右と一致するものに限定されるものではない。

【発明の実施の形態】
以下、図１〜図７を参照して紙幣分類機に適用した発明の実施の形態を説明する。
【００１４】
図１に紙幣分類機１の概略構造を示す。この紙幣分類機１は、前面側（図１において左側）の下部位置に紙幣挿入部２を有する。紙幣挿入部２は、短手一括で挿入される紙幣Ｐを挿入方向の前方に向け下方に傾斜する姿勢で前揃えして受け入れるもので、最下位の紙幣Ｐから一枚ずつ繰り出すよう、挿入された紙幣群の最下面に面してキックローラ３が配置され、その繰出方向前方には前後にフィードローラ４，５が配置され、これらフィードローラ４，５にフィードベルト６が巻掛けられている。また、フィードベルト６を挟んで後側のフィードローラ５に対向する位置にゲートローラ７が配置されている。
【００１５】
また、紙幣分類機１には、上記紙幣挿入部２の繰出方向後方（図１において右方）の紙幣搬送路８の途中にあって、紙幣挿入部２から繰り出される紙幣Ｐの金種および真偽を識別する紙幣識別部９が配置されている。
【００１６】

【００１７】
また、紙幣分類機１には、それぞれが上部に一時保留室を有し下部に収納室を有する第１から第６の各収納ユニット１３，１４，１５，１６，１７，１８が前後一列に配置されている。図において１３ａ，１４ａ，１５ａ，１６ａ，１７ａ，１８ａは各収納ユニット１３，１４，１５，１６，１７，１８の各一時保留室であり、１３ｂ，１４ｂ，１５ｂ，１６ｂ，１７ｂ，１８ｂは各収納室である。
【００１８】
紙幣搬送路８は、各収納ユニット１３，１４，１５，１６，１７，１８の上方に延び、途中、第１から第５までの各収納ユニット１３，１４，１５，１６，１７の上方において分岐し第１から第５までの各収納ユニット１３，１４，１５，１６，１７に紙幣を送り込むよう各送り込み通路１９，２０，２１，２２，２３を有し、また、各分岐点にそれぞれ切換装置２４，２５，２６，２７，２８を有している。また、紙幣搬送路８の終端部は第６収納ユニット１８に上方から紙幣を送り込む第６送り込み通路２９となっている。
【００１９】
図１において紙面手前側の紙幣分類機１の前面板３０Ａには、各収納ユニット１３，１４，１５，１６，１７，１８上部の各一時保留室１３ａ，１４ａ，１５ａ，１６ａ，１７ａ，１８ａの位置にそれぞれ常時開放の第１の取出口３１，３２，３３，３４，３５，３６が設けられ、また、各収納ユニット１３，１４，１５，１６，１７，１８の各収納室１３ｂ，１４ｂ，１５ｂ，１６ｂ，１７ｂ，１８ｂの位置には、各第２の取出口３７，３８，３９，４０，４１，４２が設けられている。そして、上記第２の取出口３７，３８，３９，４０，４１，４２を一括して開閉するよう開閉扉４３が設置されている。この開閉扉４３は、下方３箇所が蝶板４４，４５，４６で上記前面板３０Ａに連結されたものである。また、前面板３０Ａには、各収納ユニット１３，１４，１５，１６，１７，１８の上方に各カウント表示部４７，４８，４９，５０，５１，５２が設けられいる。また、図において、３０Ｂは紙幣分類機１の背板を示す。
【００２０】
第１から第６の各収納ユニット１３，１４，１５，１６，１７，１８は、各収納室１３ｂ，１４ｂ，１５ｂ，１６ｂ，１７ｂ，１８ｂの下部底が各底板５３，５４，５５，５６，５７，５８により形成され、各一時保留室１３ａ，１４ａ，１５ａ，１６ａ，１７ａ，１８ａの各下部底が各開閉部材５９，６０，６１，６２，６３，６４により構成されている。そして、各収納ユニット１３，１４，１５，１６，１７，１８は、正面視にて左右の側板のうち、各右側板６５，６６，６７，６８，６９，７０が固定側板で、各左側板７１，７２，７３，７４，７５，７６が左右調整可能な可動側板とされている。
【００２１】
次に、上記収納ユニット１３，１４，１５，１６，１７，１８の詳細を第１収納ユニット１３を例にとって説明する。第２から第６の収納ユニット１４，１５，１６，１７，１８も構造的にはこれと同じである。
【００２２】
図２は収納ユニット（第１収納ユニット）１３を一部破断正面視にて示し、図３は同収納ユニット１３を平面視にて示す。
【００２３】
この収納ユニット１３は、前面板３０Ａと背板３０Ｂの間に右側板６５と左側板７１を備える。このうち、右側板６５は、前後が前面板３０Ａおよび背板３０Ｂに固定され、上部は別体で、その別体とされた側板上部が一時保留室１３ａの固定側壁１０１を構成している。そして、その固定側壁１０１は、上縁部が右外方に上向き傾斜するとともに、その傾斜した上縁部から下方に向けて前後に二対の切り欠き部が設けられている。そして、これら二対の切り欠き部に対応する上部右外方位置には、これら切り欠き部にそれぞれ一部入り込んで回転するよう送り込みローラ１０２および羽根車１０３が切り欠き部毎に相互に隣接した配置で設けられている。これら送り込みローラ１０２と羽根車１０３は、両端が前面板３０Ａと背板３０Ｂに支持された回転軸１０４に固定されたもので、送り込みローラ１０２が上方の紙幣搬送路８の切換装置２４手前の一対の搬送ローラ１０５，１０６と協動する位置で搬送ローラ１０６と当接状態にある。また、羽根車１０３は、上記搬送ローラ１０５，１０６とは干渉しない位置にあり、周面には放射状に各４枚のウレタン羽根１０３ａが立設されている。
【００２４】
左側板７１は、下端部が収納ユニット１３の下部において前面板３０Ａおよび背板３０Ｂの内側対向位置に突設固定された一対のピン１０７に揺動可能に支持されている。また、左側板７１の上部には前後方向に間隔をおいて一対の板バネ１０８が取り付けられ、各板バネ１０８の上面にはそれぞれラック１０９が固定されている。そして、各ラック１０９に対しそれぞれ上方から噛み合うよう収納ユニット１３の上部に一対のピニオン１１０が配置され、これらピニオン１１０が前面板３０Ａと背板３０Ｂに支持された回転軸１１１に固定されている。そして、この回転軸１１１は、一端部が背板３０Ｂの後方に配置されたモータ１１２に駆動連結されている。この構成により、モータ１１２の回転はピニオン１１０とラック１０９を介して板バネ１０８の水平移動に変換され、下端部の一対のピン１０７を支点として左側板７１が左右に揺動する。そして、モータ１１２が停止すると左側板７１が停止する。こうして一時保留室１３ａおよび収納室１３ｂの左右寸法が調整可能である。なお、図２の左側板７１の位置は最左端に寄った位置すなわち垂直状態を示す。
【００２５】
収納ユニット１３は、上述のように上部に一時保留部１３ａを有するとともに、下部に収納室１３ｂを有し、一時保留部１３ａの下部底が開閉部材５９によって構成されたものである。そして、その開閉部材５９は、左右一対の揺動部材２０１，２０２と、一対の第１支持部材２０３，２０４と、一対の第２支持部材２０５，２０６とから構成されたものであり、これら揺動部材２０１，２０２，第１支持部材２０３，２０４および第２支持部材２０５，２０６が左右で各々ユニットとなっている。図４はその左側ユニットの平面図であり、図５は右側ユニットの平面図である。
【００２６】
上記一対の揺動部材２０１，２０２は、各々が平板状の部材で、一時保留室１３ａの下部の左右側方において水平方向に並ぶ配置で前面板３０Ａと背板３０Ｂに支持された各支軸２０７，２０８に固定され、これら各支軸２０７，２０８を中心に左右対称に所定角度揺動して、各々が全体として上向きで各先端が両支軸間の内側上方で向き合う上向き姿勢（図２に一点鎖線で示す姿勢）と、各々が全体として水平で両支軸２０７，２０８間の内側に位置する水平姿勢（図２および図３に実線で示す姿勢）と、各々が全体として下向きの下向き姿勢（図２に二点鎖線および三点鎖線で示す姿勢）をとるよう構成されたものである。これら一対の揺動部材２０１，２０２は、図２および図３に実線で示す水平姿勢において先端が重なり合わず、間に所定の間隙が残る寸法のもので、各先端を水平姿勢において下方へ左右対称に所定角度（鋭角）曲折する方向に所定長さだけ一体延設する形で各第１支持部材２０３，２０４が設けられている。
【００２７】
各第１支持部材２０３，２０４は、各々が指状で、各揺動部材２０１，２０２毎に複数個（図示の例では各４個）設けられ、それらが上記揺動部材２０１，２０２の水平姿勢において反対側の揺動部材の切り欠き部に入り込み、あるいは相互に反対側の第１支持部材の下側に入り込む指組み状態となり、また、一対の揺動部材２０１，２０２の揺動範囲において相互に干渉しない配置で、かつ、一対の揺動部材２０１，２０２が上向き姿勢にある時に水平となって、一時保留室１３ａ内の集積状態の紙幣Ｐ群の最下面の中央域を支持するよう構成されている。
【００２８】
また、上記各第２支持部材２０５，２０６は、各々がくの字状に形成されたもので、各揺動部材２０１，２０２に対し、それら一対の揺動部材２０１，２０２の揺動範囲において相互に干渉しないとともに一対の第１支持部材２０３，２０４と干渉しない配置で、各揺動部材２０１，２０２毎に２個ずつ設けられている。
【００２９】
各第２支持部材２０５，２０６は、各揺動部材２０１，２０２の各支軸２０７，２０８とは反対の先端側の前後２箇所の各支持部２０９，２１０に組み付けられた各支持軸２１１，２１２に上記くの字の曲がり部が支持され、また、各支軸２０７，２０８側に延びる部分が各揺動部材２０１，２０２の上面に重なり、かつ、各先端が各揺動部材２０１，２０２の各開口部２１３，２１４にはまり込むよう構成されている。また、これら第２支持部材２０５，２０６は、各々の支持中心の位置に重錘２１５，２１６を有する。そして、各第２支持部材２０５，２０６は、各支持軸２１１，２１２を中心に各揺動部材２０１，２０２に対して揺動可能で、一対の揺動部材２０１，２０２が上向き姿勢から水平姿勢の間にある時に保留室内の集積状態の紙幣類Ｐ群を支持する水平姿勢を保つとともに、一対の揺動部材２０１，２０２が下向き姿勢をとる時に、落下する紙幣Ｐ群と干渉しない姿勢を保つ。そして、一対の揺動部材２０１，２０２が上向き姿勢にある時に一時保留室１３ａ内の集積状態の紙幣Ｐ群の最下面の左右の端部域を支持し、一対の揺動部材２０１，２０２が水平姿勢にある時にはそれら紙幣Ｐ群の最下面を広い範囲で安定支持する。
【００３０】
また、収納ユニット１３の正面視にて左側の揺動部材２０１の支軸２０７には、その背板３０Ｂ側の端部に該支軸２０７を中心として所定角度（図示の例では１３０゜）をなす配置で外面側に二つのピン２１７，２１８を有する従動側円板部材２１９が固定されている。この円板部材２１９の二つのピン２１７，２１８は、一対の揺動部材２０１，２０２の上向き姿勢（定位置）において、図６に示すように第１のピン２１７が支軸２０７に対し水平外方に並び、第２のピン２１８が支軸２０７の内側斜め下方に位置するよう配置されたものである。
【００３１】
また、収納ユニット１３の正面視にて右側の揺動部材２０２の支軸２０８の背板３０Ｂ側の端部には、該揺動部材２０２に対し下方内側に所定角度（図示の例では３０゜）をなす配置で短寸のレバー部材２２０が固定されている。
【００３２】
そして、これら円板部材２１９とレバー部材２２０を介して各支軸２０７，２０８を連動させ、一対の揺動部材２０１，２０２を左右対称に揺動させるよう、連動用ロッド部材２２１が配設されている。このロッド部材２２１は、一端が円板部材２１９の第１のピン２１７に回動自在に連結され、他端がレバー部材２２０の先端部外面に立設されたピン２２２に回動自在に連結されたものである。
【００３３】
また、上記円板部材２１９の下方で該円板部材２１９から所定寸法離れた背板３０Ｂ外側の位置には、円面３箇所の所定角度位置に第１から第３の突起状のセンサ部２２３，２２４，２２５を有するとともに外面偏心位置にピン２２６を備えた駆動側円板部材２２７が配置されている。そして、この駆動側円板部材２２７のピン２２６と上記左側の支軸２０７に固定された従動側円板部材２１９の第２のピン２１８を連結するよう駆動用ロッド部材２２８が配設されている。この駆動用ロッド部材２２８は、一端が駆動側円板部材２２７のピン２２６に回動自在に連結され、他端が従動側円板部材２１９の第２のピン２１８に回動自在に連結されたものである。
【００３４】
上記駆動側円板部材２２７は背板３０Ｂに回転可能に支持された駆動軸２２９に固定されている。その駆動軸２２９は駆動ギヤ２３０を介してモータ２３１により駆動される。
【００３５】
このように従動側円板部材２１９，レバー部材２２０，連動用ロッド部材２２１，駆動側円板部材２２７，駆動用ロッド部材２２８，駆動軸２２９，駆動ギヤ２３０およびモータ２３１によって上記一対の揺動部材２０１，２０２の駆動機構が構成されている。
【００３６】
また、収納ユニット１３の背板３０Ｂには、収納ユニット１３の正面視にて上記駆動側円板部材２２７の各センサ部２２３，２２４，２２５の回動軌跡に重なり、かつ、駆動側円板２２７の中心を挟んで対向する所定の位置に第１および第２の位置センサ２３２，２３３が設置されている。これら位置センサ２３２，２３３は、上記各センサ部２２３，２２４，２２５と協動して駆動軸２２９の回動位置を検知するものである。これら各センサ部２２３，２２４，２２５と各位置センサ２３２，２３３とは、図６に示す定位置において第１のセンサ部２２３が第１の位置センサ２３２に重なるとともに、第２のセンサ部２２４が第２の位置センサ２３３に重なり、図２に実線で示す一時保留の位置で第３のセンサ部２２５が第１の位置センサ２３２に重なり、図７に示す開放位置で第１のセンサ部２２３が第２の位置センサ２３３に重なるとともに、第２のセンサ部２２４が第１の位置センサ２３２に重なるよう配置されたものである。
【００３７】
駆動ギヤ２３０を介してモータ２３１により駆動軸２２９が回転されると、その回転は駆動用ロッド部材２２８および円板部材２１９を介して左側の揺動部材２０１の支軸２０７に伝達されて、左側の揺動部材２０１が揺動し、また、その支軸２０７の回転は連動用ロッド部材２２１およびレバー部材２２０を介して右側の揺動部材２０２に伝達され、右側の揺動部材２０２が左側の揺動部材２０１と同期して左右対称となるよう揺動する。そして、これら一対の揺動部材２０１，２０２の揺動位置は、上記各位置センサ２３２，２３３の信号によって検知され、その信号に基づいて図示しない制御部により一対の揺動部材２０１，２０２が上向き姿勢（定位置），水平姿勢（一時保留位置）および下向き姿勢（開放位置）をとるよう制御される。
【００３８】
一対の揺動部材２０１，２０２が上向き姿勢（定位置）にある時の駆動機構の動作状態は図６に示すとおりである。この時、一対の揺動部材２０１，２０２は左右対称に水平方向に対し所定角度（図示の例では４０゜）上向きに傾斜し、各第１支持部材２０３，２０４は水平である。また、各第２支持部材２０５，２０６は重錘２１５によって水平姿勢に保たれる。この状態で、保留室１３ａ内の集積状態の紙幣Ｐ群は最下面の中央域が各第１支持部材２０３，２０４により支持され、最下面の左右の端部域が各第２支持部材２０５，２０６により支持される。また、この時の駆動側円板部材２２７の回転位置は、第１のセンサ部２２３が第１の位置センサ２３２に重なるとともに第２のセンサ部２２４が第２の位置センサ２３３に重なることによって検知される。
【００３９】
また、図２に実線で示す一時保留の状態は、上記図６の定位置の状態から駆動軸２２９が反時計回り方向に所定角度（図示の例では約６０゜）回転した状態であって、この状態では、一対の揺動部材２０１，２０２は水平姿勢で、一対の第１支持部材２０３，２０４は下向き姿勢である。また、各第２支持部材２０５，２０６は各揺動部材２０１，２０２の上面に重なって水平姿勢に保たれる。そして、保留室１３ａ内の集積状態の紙葉類Ｐ群は最下面の広い範囲が各第２支持部材２０５，２０６により支持された状態となる。また、この時の駆動側円板部材２２７の回転位置は、第３のセンサ部２２５が第１の位置センサ２３２に重なることにより検知される。
【００４０】
また、一対の揺動部材２０１，２０２が下向き姿勢（開放位置）にある時の駆動機構の動作状態は図７に示すとおりである。この状態は上記図２の一時保留の状態から駆動軸２２９が更に反時計回り方向に所定角度（図示の例では約１２０゜）回転した状態であって、この状態では、一対の揺動部材２０１，２０２は垂直下向き姿勢で、一対の第１支持部材２０３，２０４は下外方に向く。また、この時、各第２支持部材２０５，２０６は重錘２１５により各揺動部材２０１，２０２の上面に重なって、垂直姿勢に保たれる。そして、保留室１３ａ内の紙葉類Ｐ群を下方の収納室１３ｂに落下させる。また、この時の駆動側円板部材２２７の回転位置は、第１のセンサ部２２３が第２の位置センサ２３３に重なるとともに、第２のセンサ部２２４が第１の位置センサ２３３に重なることによって検知される。
【００４１】

【００４６】
上記紙幣分類機１には、金種分類とバッチ計数と方向別分類の三つの機能モードがあり、モードの選択により各モードの処理が可能である。
【００４７】
そのうち、金種分類は、指定された国の紙幣を最大６金種に分類する機能モードであって、この時、各収納ユニット１３，１４，１５，１６，１７，１８の各左側壁７１，７２，７３，７４，７５，７６は、各モータ１１２により各々ピニオン１１０およびラック１０９を介してそれぞれの金種対応位置へ揺動され、その位置に保持される。また、一対の揺動部材２０１，２０２は最初は定位置（上向き姿勢）にある。そして、紙幣Ｐが繰り出され、紙幣識別部９により金種識別されると、その識別された金種に応じて切換装置２４，２５，２６，２７，２８が作動し、対応する収納ユニット１３，１４，１５，１６，１７，１８の一時保留室１３ａ，１４ａ，１５ａ，１６ａ，１７ａ，１８ａに紙幣Ｐが送り込まれる。そして、紙幣Ｐの送り込み枚数に応じて、各モータ２３１のパルス駆動により各一対の揺動部材２０１，２０２は図２に示す正面視にて時計回り方向に揺動し、紙幣Ｐが集積していく。そして、各一対の揺動部材２０１，２０２は金種別のフル枚数の手前（フル枚数が１００枚であれば約９０枚の時点）で水平姿勢とされ、その後、フル枚数に達するまで水平姿勢を保つ。そして、紙幣識別部９による金種別フル枚数検知によっていずれかの金種のフル枚数（例えば１００枚）が検知されると、紙幣繰り出しが一時停止されるとともに、モータ２３１によって対応金種の収納ユニットの一対の揺動部材２０１，２０２が下向き姿勢（開放位置）とされ、紙幣Ｐ群は収納室１３ｂに自重で重積収納される。その後、モータ２３１が逆方向に回転することによって、一対の揺動部材２０１，２０２は逆方向に揺動し、定位置に復帰する。そして、その直後に紙幣繰り出しが再開される。
【００４８】
なお、分類終了時に所定枚数（一対の揺動部材２０１，２０２が水平姿勢に移行する枚数）に達しない金種がある場合は、その分類終了の時点で一対の揺動部材２０１，２０２が水平姿勢まで揺動される。この場合、紙幣識別部９に所定時間紙幣が来ないことと、紙幣挿入部に紙幣が無いことを条件に、分類終了と判定される。そして、その時点で一対の揺動部材２０１，２０２は水平姿勢まで揺動され、その後、所定時間（紙幣識別部９を通過した紙幣を一時保留室１３ａ，１４ａ，１５ａ，１６ａ，１７ａ，１８ａに送り込める時間）が経過した時点で一対の揺動部材２０１，２０２は下向き姿勢（開放位置）となり、次いで、上向き姿勢（定位置）に復帰する。
【００４９】
また、各カウント表示部４７，４８，４９，５０，５１，５２には紙幣識別部９を通過した紙幣の金種別枚数表示がなされる。
【００５０】
また、満杯検知センサ２４７によって収納室１３ｂ，１４ｂ，１５ｂ，１６ｂ，１７ｂ，１８ｂのいずれかの満杯状態が検知されると、紙幣繰り出しが停止される。そして、開閉扉４３を開放し収納紙幣を取り除いた後、スタート釦（図示せず）を押すと、紙幣繰り出しが再開される。
【００５１】
また、バッチ計数は、最初に識別し計数した金種の紙幣を指定枚数（例えば１００枚）毎に分ける機能モードである。この場合は、全ての収納ユニット１３，１４，１５，１６，１７，１８は各左側壁７１，７２，７３，７４，７５，７６が紙幣識別部９において最初に識別された金種に対応する位置に自動的に調整される。そして、紙幣識別部９を通った紙幣のうち、最初に識別された金種以外の紙幣はリジェクト部１０へ排出され、最初に識別された金種の紙幣は、紙幣識別部９に近い方（図１において左）から順に各収納ユニット１３，１４，１５，１６，１７，１８に所定枚数（例えば１００枚）ずつ送り込まれ、各一時保留室１３ａ，１４ａ，１５ａ，１６ａ，１７ａ，１８ａに収納される。この時、各一時保留室１３ａ，１４ａ，１５ａ，１６ａ，１７ａ，１８ａの一対の揺動部材２０１，２０２は上記所定枚数の手前（上記所定枚数が１００枚であれば約９０枚の時点）で水平姿勢とされ、その後、水平姿勢を保つ。そして、これら収納ユニット１３，１４，１５，１６，１７，１８にそれぞれ所定枚数の紙幣Ｐが収納された後は、各カウント表示部４７，４８，４９，５０，５１，５２に設けられた図示しない取出し釦を押すことにより、各押出し棒２４１が作動して、その一時保留室１３ａ，１４ａ，１５ａ，１６ａ，１７ａ，１８ａに収納された紙幣Ｐ群を前方（図１において手前側）に押し出す。この時、札長が短いと紙幣は第１の取出口３１，３２，３３，３４，３５，３６まで達せず、札長が長い紙幣の場合は第１の取出口３１，３２，３３，３４，３５，３６から外へ一部突出するが、いずれの場合も、紙幣Ｐは前方に押し出されることによって第１の取出口３１，３２，３３，３４，３５，３６からの取り出しが容易となる。そして、操作者が紙幣Ｐを取り出すと、札抜取センサ２４６がそれを検知することにより、押出し棒２４１の待機位置への復帰と、揺動部材２０１，２０２の定位置への復帰が行われ、再度のバッチ収納に備えた状態となる。なお、このモードの時は、揺動部材２０１，２０２は下向き姿勢（開放位置）はとらず、上向き姿勢から水平姿勢までの揺動となる。
【００５２】
また、方向別分類は、ある金種の紙幣を表裏と前後位置の取り合わせで決まる４方向（表前，表後，裏前，裏後）に分類し方向別に計数する機能モードであって、最初に識別した金種について、紙幣識別部９に近い方（図１において左）から４個の収納ユニット１３，１４，１５，１６の左側壁７１，７２，７３，７４を自動的に最初に識別した金種の紙幣幅に対応する位置へ調整するよう、紙幣識別部９からの指令により制御部によって左側壁調整用のモータ１１２の回転位置が制御される。それ以外の金種についてはリジェックトされる。その後の動作は上述の金種分類の場合と同じである。
【００５３】
なお、上の例は、各揺動部材の先端に第１支持部材が一体で曲折形成されたものであるが、これら第１支持部材は別個に形成して揺動部材に固定するようにしてもよいものである。
【００５４】
また、上の例は、一対の第１支持部材が揺動部材の定位置（最上昇位置）において共に水平状態となるものであるが、これら第１支持部材は、定位置において一対の揺動部材揺動部材との接続側である基端部が先端部より上方に位置するような構成のものであってもよく、あるいは、その反対に定位置において先端部が基端部より上方に位置するような構成のものであってもよい。
【００５５】
また、上の例は、第２支持部材が揺動部材に支持軸で支持させたものであるが、第２支持部材は第１支持部材に支持軸で支持させるようにしてもよい。
【００５６】
また、上の例は、各収納ユニット毎に一対の揺動部材を１個のモータで駆動するものであるが、それぞれの収納ユニットについて左右揺動部材を別々のモータで駆動するようにしてもよい。
【００５７】
また、上の例は紙幣分類機の場合であるが、本発明は、その他、紙幣入金機，紙幣入出金機，循環式紙幣入出金機にも適用でき、また、一個の収納ユニットだけを用い、紙幣両替機に組み込み、紙幣識別部を通って送り込まれる紙幣を一時保留して、客の操作指令で返却または収納する紙幣ユニットにも適用でき、また、紙幣以外のシートの識別分類機にも適用できるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a paper sheet storage device of a paper sheet processing machine, and in particular, includes a storage chamber that accepts paper sheets fed one by one and temporarily stores them in an accumulated state, and opens and closes the bottom bottom of the storage chamber. Constructed by a member, the paper sheet is held on the opening and closing member in the closed state of the opening and closing member, temporarily held in the holding chamber in the accumulated state, and the group of paper sheets temporarily held in the accumulated state is dropped by opening the opening and closing member The present invention relates to a paper sheet storage device of a paper sheet processing machine that is stored in a storage room below the storage room.
[0002]
[Prior art]
As shown in Japanese Patent Publication No. 3-33616, for example, as a paper sheet storage device of a paper sheet processing machine having a storage chamber that accepts paper sheets fed one by one and temporarily stores them in an accumulated state. The lower bottom of the holding chamber is constituted by an opening / closing member, and when the opening / closing member is closed, the paper sheets are held on the opening / closing member and temporarily held in the holding chamber in the accumulated state, and the paper temporarily held in the accumulated state 2. Description of the Related Art Conventionally, a leaf group is dropped by opening an opening / closing member so as to be stored in a storage chamber below a holding chamber.
[0003]
The open / close member of the above-mentioned conventional device is composed of a pair of movable plates that swing symmetrically about the support shaft, and holds the paper sheets when the pair of movable plates is in a horizontal posture, and in a vertical posture. By opening, the paper sheets are collectively dropped into the storage unit.
[0004]
[Problems to be solved by the invention]
The above-described conventional paper sheet holding device of the paper sheet processing machine accepts and temporarily holds paper sheets fed one by one by swinging a pair of movable plates to take a horizontal posture and a vertical posture. In addition, the paper sheet group on the movable plate when it is dropped into the storage unit and sent to the holding chamber one by one is temporarily positioned because the position of the lowermost surface of the paper sheet group is constant. When the number of reserved sheets is large, the difference from the feeding position is large. Therefore, when the number of feeding sheets is small, the drop height is large, and the fed paper sheets are in a standing state and the trailing edge is raised. The paper sheet is dropped like this, and the leading edge of the paper sheet to be fed next hits the rear end part that floats up, and a jam occurs.
[0005]
In order to prevent jamming, it is conceivable to move the movable plate up and down in a horizontal position according to the number of sheets fed in. However, the open / close member is moved in parallel, and In order to open the opening / closing member at a point, the mechanism must be complicated, and the cost is high. In order to prevent jamming, it is conceivable that the pair of movable plates are placed in an upward posture and close to a horizontal posture in accordance with the number of paper sheets fed, but such a movable plate is simply placed in an upward posture. Then, even if the accumulated paper sheet group can support the central area of the lowermost surface, a gap is formed below the left and right end areas, and therefore the accumulated paper sheet group is inclined and a jam is generated.
[0006]
Accordingly, it is a problem to prevent jamming in the paper sheet storage device of the paper sheet processing machine in which the lower bottom of the storage chamber is configured by an opening / closing member, and to simplify the mechanism and reduce the cost. The present invention aims to solve this problem.
[0007]
[Means for Solving the Problems]
The paper sheet storage device of the paper sheet processing machine of the present invention includes a storage chamber that accepts paper sheets fed one by one and temporarily stores them in an accumulated state, and the lower bottom of the storage chamber is configured by an opening / closing member. In the closed state of the opening and closing member, the paper sheets are held on the opening and closing member and temporarily held in the holding chamber in the accumulated state, and the group of paper sheets temporarily held in the accumulated state is dropped by opening the opening and closing member, The storage chamber is configured to include a pair of swing members, a pair of first support members, and a pair of second support members as opening / closing members, and swing the pair of swing members. The pair of oscillating members oscillate at a predetermined angle symmetrically about the respective support shafts arranged horizontally in the left and right sides of the lower part of the holding chamber, and each of the tip ends upward as a whole. Facing upward on the inner upper side between both spindles And a pair of first support members are formed of a pair of oscillating members. Each tip is provided with an arrangement that does not interfere with each other in the swing range of the pair of swing members, and when the pair of swing members are in an upward posture, the central area of the lowermost surface of the stacked paper sheets in the holding chamber The pair of second support members are configured to support each other, and the pair of second support members do not interfere with each other in the swing range of the pair of swing members from the upward posture to the horizontal posture with respect to the pair of first support members. In addition, it is provided so as to be swingable about the support shaft in an arrangement that does not interfere with the pair of first support members, and when the pair of swing members are between an upward posture and a horizontal posture, Supports the left and right edge areas on the bottom surface As are those that you configured.
[0008]
Here, the second support member has a weight, and the weight supports the stacked paper sheets in the holding chamber when the pair of swinging members is between the upward posture and the horizontal posture. It is preferable to maintain the posture in which the pair of swinging members move integrally with the pair of swinging members when the pair of swinging members assumes a downward posture.
[0009]
The sheets fed one by one to the sheet storage device of the sheet processing machine configured as described above are held and accumulated by the opening / closing member in the closed state of the opening / closing member constituting the lower bottom of the reservation chamber. Is temporarily held in the holding room. Further, the paper sheets temporarily held in the storage chamber in a stacked state fall when the opening / closing member is opened and are stored in the storage chamber. The opening and closing member receives and holds the sheets fed one by one, and when the stacking member is temporarily held in the holding chamber, the pair of swinging members faces upward at the front ends of the inner sides between the support shafts. At the position where the pair of first support members are lifted upward, the pair of second support members support the central area of the lowermost surface of the stacked paper sheet group and the left and right end areas of the stacked paper sheet group. To support. At that time, since the stacked paper sheet group is supported at the lifting position by the pair of first support members and the pair of second support members, even when the set number of temporarily reserved sheets is large, the uppermost surface of the paper sheet group and the feeding position The drop becomes small, and the drop is always kept small by swinging the pair of swing members toward the horizontal posture in accordance with the number of sheets fed. Therefore, there is no occurrence of jam, and the paper sheets are smoothly accepted and accumulated and held.
[0010]
The opening / closing member constituting the lower bottom of the holding chamber moves both the vertical position and the opening position of the stacked paper sheet group by swinging the first swinging member. Since the same driving mechanism is used, the cost can be reduced and the structure can be simplified.
[0011]
In the above description, “left and right” is not limited to the same as the left and right of the machine as a whole. Further, “left and right” in the claims is not limited to the same as the left and right of the machine.
[0012]
Further, in the above description, “paper sheets” covers not only banknotes but also sheets of cards, slips, bills, checks, postcards and the like. Similarly, “paper sheets” in the claims covers not only banknotes but also sheets of cards, slips, bills, checks, postcards and the like.

A billless detection sensor 248 is installed (see FIG. 2).
[0046]
The banknote sorter 1 has three functional modes: denomination classification, batch counting, and direction classification, and each mode can be processed by selecting a mode.
[0047]
Among them, the denomination classification is a function mode for classifying banknotes in a designated country into a maximum of six denominations. At this time, each left side wall 71, each of the storage units 13, 14, 15, 16, 17, 18 is stored. 72, 73, 74, 75 and 76 are swung to the respective denomination corresponding positions by the motors 112 via the pinions 110 and the racks 109, and are held at these positions. In addition, the pair of swing members 201 and 202 is initially in a fixed position (upward posture). Then, when the bill P is fed out and denominated by the bill identifying unit 9, the switching devices 24, 25, 26, 27, 28 are operated according to the identified denomination, and the corresponding storage units 13, The bills P are fed into the temporary holding chambers 13a, 14a, 15a, 16a, 17a, 18a of 14, 15, 16, 17, 18. Then, according to the number of fed banknotes P, each pair of swinging members 201 and 202 swings clockwise in the front view shown in FIG. Go. Each pair of swinging members 201 and 202 is set to the horizontal posture before the full number of denominations (at the time of about 90 if the full number is 100), and then the horizontal posture is reached until the full number is reached. keep. When the full number of denominations (for example, 100) is detected by detecting the full number of denominations by the banknote recognition unit 9, bill feeding is temporarily stopped and the corresponding denomination storage unit is stopped by the motor 231. The pair of swinging members 201 and 202 are in a downward posture (open position), and the banknotes P are stacked and stored in the storage chamber 13b with their own weight. Thereafter, when the motor 231 rotates in the reverse direction, the pair of swinging members 201 and 202 swings in the reverse direction and returns to the home position. And banknote feeding is restarted immediately after that.
[0048]
When there is a denomination that does not reach the predetermined number (the number of the pair of swinging members 201 and 202 that shifts to the horizontal position) at the end of the classification, the pair of swinging members 201 and 202 is horizontally positioned at the end of the classification. It is swung to the posture. In this case, it is determined that the classification is completed on the condition that no banknote arrives at the banknote recognition unit 9 for a predetermined time and there is no banknote in the banknote insertion unit. At that time, the pair of swinging members 201 and 202 are swung to a horizontal posture, and then the bills that have passed through the bill recognition unit 9 are temporarily stored in the temporary storage chambers 13a, 14a, 15a, 16a, 17a, and 18a. The pair of oscillating members 201 and 202 are in a downward posture (open position) at a time point when a time during which the feed can be performed, and then return to an upward posture (fixed position).
[0049]
The count display units 47, 48, 49, 50, 51, 52 display the number of denominations of banknotes that have passed the banknote identification unit 9.
[0050]
Further, when the full detection sensor 247 detects that the storage chambers 13b, 14b, 15b, 16b, 17b, and 18b are full, the bill feeding is stopped. Then, after opening the open / close door 43 and removing the stored banknote, when a start button (not shown) is pressed, banknote feeding is resumed.
[0051]
The batch counting is a function mode in which the banknotes of denominations that are first identified and counted are divided for each specified number of sheets (for example, 100 sheets). In this case, all the storage units 13, 14, 15, 16, 17, and 18 correspond to the denominations that the left side walls 71, 72, 73, 74, 75, and 76 are first identified in the bill identifying unit 9. Automatically adjust to position. And among the banknotes which passed through the banknote identification part 9, banknotes other than the denomination identified first are discharged to the rejection part 10, and the banknote of the denomination identified first is closer to the banknote identification part 9 ( A predetermined number (for example, 100 sheets) is sequentially fed into the storage units 13, 14, 15, 16, 17, and 18 in order from the left in FIG. 1 and stored in the temporary storage chambers 13a, 14a, 15a, 16a, 17a, and 18a. Is done. At this time, the pair of oscillating members 201, 202 in each temporary holding chamber 13a, 14a, 15a, 16a, 17a, 18a is in front of the predetermined number (about 90 when the predetermined number is 100). The horizontal posture is assumed, and then the horizontal posture is maintained. Then, after a predetermined number of banknotes P are stored in the storage units 13, 14, 15, 16, 17, 18, the illustrations provided in the count display units 47, 48, 49, 50, 51, 52 are shown. Each push-out bar 241 is actuated by pushing the take-out button, and the banknotes P stored in the temporary holding chambers 13a, 14a, 15a, 16a, 17a, 18a are pushed forward (front side in FIG. 1). . At this time, if the bill length is short, the banknote does not reach the first outlets 31, 32, 33, 34, 35, 36, and if the bill length is long, the first outlets 31, 32, 33, 34 are used. , 35, and 36, and in some cases, the banknote P is pushed forward to facilitate removal from the first outlets 31, 32, 33, 34, 35, and 36. . Then, when the operator takes out the banknote P, the bill removal sensor 246 detects it, thereby returning the push-out bar 241 to the standby position and returning the swinging members 201 and 202 to the fixed positions. It will be in a state ready for batch storage again. In this mode, the swinging members 201 and 202 do not take a downward posture (open position) but swing from an upward posture to a horizontal posture.
[0052]
The direction-specific classification is a function mode in which a banknote of a denomination is classified into four directions (front, front, back, front, back, and back) determined by the combination of front and back and front and back positions, and counting by direction. First, the left side walls 71, 72, 73, 74 of the four storage units 13, 14, 15, 16 are automatically identified first from the side closer to the banknote recognition unit 9 (left in FIG. 1). The rotation position of the motor 112 for adjusting the left side wall is controlled by the control unit in response to a command from the banknote identification unit 9 so as to adjust to the position corresponding to the banknote width of the denomination. Other denominations will be rejected. The subsequent operation is the same as in the case of the above denomination classification.
[0053]
In the above example, the first support member is integrally bent at the tip of each swing member. However, these first support members are formed separately and fixed to the swing member. Is also good.
[0054]
In the above example, the pair of first support members are both in a horizontal state at the fixed position (the highest position) of the swing member. The base end portion that is the connection side with the member swinging member may be configured to be positioned above the tip end portion, or conversely, the tip end portion is positioned above the base end portion at a fixed position. The thing of the structure to do may be used.
[0055]
In the above example, the second support member is supported by the swing member on the support shaft. However, the second support member may be supported by the first support member on the support shaft.
[0056]
In the above example, the pair of swing members is driven by one motor for each storage unit, but the left and right swing members may be driven by separate motors for each storage unit. Good.
[0057]
Moreover, although the above example is a case of a banknote sorting machine, the present invention can also be applied to a banknote depositing machine, a banknote depositing / dispensing machine, a circulating banknote depositing / dispensing machine, and only one storage unit is used. It can also be applied to a banknote unit that is built in a banknote change machine, temporarily holds a banknote sent through a banknote recognition unit, and is returned or stored by a customer's operation command. Applicable.
