Description

本発明は、集積部への紙葉類の集積処理又は集積部からの紙葉類の繰出処理を行う紙葉類集積繰出装置に係り、特に、装置への紙葉類の搬送状態にかかわらず好適に紙葉類の集積処理及び繰出処理を行うことができる紙葉類集積繰出装置に関する。   The present invention relates to a paper sheet stacking and feeding device that performs paper sheet stacking processing on a stacking unit or paper sheet feeding processing from a stacking unit, and in particular regardless of the state of transport of paper sheets to the device. The present invention relates to a paper sheet stacking and feeding device capable of suitably performing paper sheet stacking and feeding processes.

従来、紙幣などの紙葉類を入金又は出金の如き集積処理又は繰出処理を行う場合には、ＡＴＭ（Ａｕｔｏｍａｔｅｄ Ｔｅｌｌｅｒ Ｍａｃｈｉｎｅ）などの装置が広く利用されており、このような装置には、紙葉類集積繰出装置が搭載されている。   2. Description of the Related Art Conventionally, devices such as ATM (Automated Teller Machine) have been widely used when paper sheets such as banknotes are subjected to a stacking process such as depositing or dispensing, or a dispensing process. A leaf accumulation and feeding device is mounted.

例えば、このような紙葉類集積繰出装置として、以下に示すような装置が提案されている（例えば、特許文献１及び２参照）。具体的には、図１１に示すように、紙葉類集積繰出装置９０は、装置外部の搬送部より１枚ずつ送られてくる紙葉類P１を、フィードローラ３０及びゲートローラ４０の間に挟み込んで、これらのローラ３０，４０を集積回転方向（図中の矢印方向）Rに回転させる。これにより、紙葉類Pは、集積空間７１内に導かれて集積部７に集積される。   For example, the following apparatus has been proposed as such a paper sheet stacking and feeding apparatus (see, for example, Patent Documents 1 and 2). Specifically, as shown in FIG. 11, the paper sheet stacking and feeding device 90 transfers the paper sheets P1 fed one by one from the conveyance unit outside the device between the feed roller 30 and the gate roller 40. These rollers 30 and 40 are rotated in the stacking rotation direction (arrow direction in the figure) R. Thus, the paper sheet P is guided into the accumulation space 71 and accumulated in the accumulation unit 7.

このゲートローラ４０は、図１２に示すように、回転シャフト４１に取着されており、ゲートローラ４０の両端には、複数の羽根車８０がゲートローラ４０と同軸に配設されている。各複数の羽根車８０は、四枚の弾性羽根部８３が設けられており、弾性羽根部８３は、集積回転方向Rに倒れ込むように放射状に形成されている。このような羽根車８０は、ゲートローラ４０の集積回転方向Ｒの回転と共に回転し、この回転により弾性羽根部８３が、放射状に広がる。   As shown in FIG. 12, the gate roller 40 is attached to a rotating shaft 41, and a plurality of impellers 80 are arranged coaxially with the gate roller 40 at both ends of the gate roller 40. Each of the plurality of impellers 80 is provided with four elastic blade portions 83, and the elastic blade portions 83 are radially formed so as to fall in the accumulation rotation direction R. Such an impeller 80 rotates with the rotation of the gate roller 40 in the accumulation rotation direction R, and the elastic blade portion 83 spreads radially by this rotation.

この結果、図１１に示すように、紙葉類集積繰出装置９０を作動させて、集積処理を行った場合には、紙葉類Ｐ２の搬送方向の両端側が、羽根車８０の回転により広がった弾性羽根部８３によって、上方（フィードローラ３０側）に持ち上げられ、紙葉類Ｐ２は、スタックガイド７０とゲートローラ４０との間で変形される。   As a result, as shown in FIG. 11, when stacking processing is performed by operating the paper sheet stacking and feeding device 90, both ends in the transport direction of the paper sheet P <b> 2 are spread by the rotation of the impeller 80. The elastic blade 83 lifts the paper sheet P2 upward (feed roller 30 side), and the paper sheet P2 is deformed between the stack guide 70 and the gate roller 40.

この変形により、紙葉類Ｐ２の剛性が増した状態で、紙葉類Ｐ２は集積空間７１内に導かれるので、紙葉類の集積部７への集積性能は向上する。更に、図１３に示すように、紙葉類Ｐ２がフィードローラ３０、ゲートローラ４０挟持点を通過すると、紙葉類Ｐ２の後端部を羽根車８０の弾性羽根部８３の先端部８３ａが、既に集積部７において集積された紙葉類Ｐ３の上に、紙葉類Ｐ２を叩き落とす。さらに、集積部７に集積された紙葉類Ｐ３の端部が浮き上がらないように、紙葉類Ｐ３は、回転する羽根車８０の複数の弾性羽根部８３の先端部８３ａで常時押え付けられている。これにより、集積空間７１内の紙葉類Ｐ3と集積空間７１内に送られる紙葉類Ｐ３の間の衝突を防止し集積性能の信頼性を確保することができる。   Due to this deformation, the paper sheet P2 is guided into the stacking space 71 in a state where the rigidity of the paper sheet P2 is increased, so that the stacking performance of the paper sheet in the stacking unit 7 is improved. Further, as shown in FIG. 13, when the paper sheet P2 passes the nipping point of the feed roller 30 and the gate roller 40, the leading end 83a of the elastic blade part 83 of the impeller 80 is connected to the rear end of the paper sheet P2. The paper sheet P2 is beaten on the paper sheet P3 already accumulated in the accumulating unit 7. Furthermore, the paper sheet P3 is always pressed by the tip parts 83a of the plurality of elastic blade parts 83 of the rotating impeller 80 so that the end part of the paper sheet P3 collected in the collecting part 7 does not float up. Yes. Thereby, the collision between the paper sheet P3 in the stacking space 71 and the paper sheet P3 sent into the stacking space 71 can be prevented, and the reliability of the stacking performance can be ensured.

一方、集積部７に集積された紙葉類Ｐ３の繰出処理は以下のようにして行われる。具体的には、図１４に示すように、ゲートローラ４０が繰出回転方向Ｌに回転し、羽根車８０の弾性羽根部８３は、リング部８１に巻き付くように湾曲しているので、ゲートローラ４０の外径以下である。   On the other hand, the feeding process of the paper sheets P3 accumulated in the accumulation unit 7 is performed as follows. Specifically, as shown in FIG. 14, the gate roller 40 rotates in the feeding rotation direction L, and the elastic blade portion 83 of the impeller 80 is curved so as to be wound around the ring portion 81. 40 or less outer diameter.

そして、繰出処理において、ピックアップローラ６０及びフィードローラ３０が繰出回転方向Ｌ（図中の矢印方向）に回転し、羽根車８０は繰出回転方向Ｌ（図中の矢印方向）に回転することで繰出される紙葉類Ｐ３の搬送補助として下方から作用する。このように羽根車８０は、紙葉類の集積処理、繰出処理に複数の効果を紙葉類に付与することで信頼性を向上している。   In the feeding process, the pickup roller 60 and the feed roller 30 rotate in the feeding rotation direction L (the arrow direction in the figure), and the impeller 80 rotates in the feeding rotation direction L (the arrow direction in the figure). It acts from below as a conveyance aid for the paper sheet P3. In this way, the impeller 80 improves reliability by providing a plurality of effects to the paper sheets in the paper sheet stacking process and feeding process.

上述のように、羽根車８０は紙葉類に複数の作用を与えることになる。その１つとして、羽根車８０は、紙葉類Ｐ２を集積空間７１内へ正常に進入するために、羽根車８０の弾性羽根部８３で紙葉類Ｐ２の両端部を変形させて、紙葉類Ｐ２の剛性を高めている。   As described above, the impeller 80 gives a plurality of actions to the paper sheets. As one of them, the impeller 80 deforms both ends of the paper sheet P2 with the elastic blade part 83 of the impeller 80 in order to normally enter the paper sheet P2 into the accumulation space 71, and the paper sheet The rigidity of the class P2 is increased.

この場合、紙葉類Ｐ２が集積空間７１内に進入する間、弾性羽根部８３は、紙葉類Ｐ２を上方へ変形させるための変形力を維持する必要がある。変形力を一定以上に維持するには、羽根車８０の弾性羽根部８３は多数形成されていることが望ましい。   In this case, while the paper sheet P2 enters the accumulation space 71, the elastic blade portion 83 needs to maintain a deformation force for deforming the paper sheet P2 upward. In order to maintain the deformation force above a certain level, it is desirable that a large number of elastic blade portions 83 of the impeller 80 be formed.

一方、多数の弾性羽根部８３を有する羽根車８０は、集積空間７１内の集積された紙葉類Ｐ３の上面を多数の弾性羽根部８３が入れ替わり接触することで、常時浮き上がりを防止するように押さえ込む効果がある。   On the other hand, the impeller 80 having a large number of elastic blade portions 83 is prevented from being lifted at all times by the large number of elastic blade portions 83 being in contact with each other on the upper surface of the accumulated paper sheets P3 in the accumulation space 71. There is an effect to hold down.

しかし、集積部７に集積された紙葉類Ｐ３は、集積空間７１内に弾性羽根部８３により叩き落とされた後は、羽根車８０の弾性羽根部８３の先端部８３ａで押さえ込まれるため、移動し難くなる。このため、紙葉類Ｐ３が、外部搬送部により偏り・傾き等の不整列状態の悪条件で、紙葉類集積繰出装置９０に搬送されている場合には、紙葉類Ｐ３が集積空間７１内において不整列状態で集積され、この状態の紙葉類Ｐ３を強制して整列させ難い問題があった。   However, since the paper sheets P3 accumulated in the accumulating unit 7 are struck down by the elastic vane 83 in the accumulating space 71, they are pressed by the tip 83a of the elastic vane 83 of the impeller 80. It becomes difficult to do. For this reason, when the paper sheet P3 is being transported to the paper sheet stacking and feeding device 90 by the external transport unit under an unaligned state such as bias or inclination, the paper sheet P3 is stored in the stacking space 71. There is a problem that it is difficult to align the paper sheets P3 in such a state that they are accumulated in a non-aligned state.

そこで、羽根車８０の弾性羽根部８３の数を減らせば、弾性羽根部８３により集積された紙葉類Ｐ３の上面を押さえない状態ができ、紙葉類Ｐ３の不整列を強制し易くなる。しかし、弾性羽根部８３の数を減らすことは、上述した羽根車８０による変形力の持続性は失われるため、集積性能は低下する問題があった。   Therefore, if the number of the elastic blade portions 83 of the impeller 80 is reduced, the upper surface of the paper sheets P3 accumulated by the elastic blade portions 83 can be prevented from being pressed, and the misalignment of the paper sheets P3 can be easily forced. However, reducing the number of the elastic blade portions 83 loses the sustainability of the deformation force by the impeller 80 described above, and thus has a problem that the accumulation performance is lowered.

本発明は上述した問題を鑑みてなされたもので、その目的とするところは、これまでの紙葉類の集積及び繰出機能を確保しつつ、集積された紙葉類の整列が容易となる紙葉類集積繰出装置を提供することにある。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a paper that facilitates the alignment of the stacked paper sheets while ensuring the functions of stacking and feeding paper sheets so far. The object is to provide a leaf accumulation and feeding device.

本発明に係る紙葉類集積繰出装置は、紙葉類の集積部と、該集積部への前記紙葉類の集積処理と前記集積部からの前記紙葉類の繰出処理とを行うフィードローラと、該フィードローラに対向して配設され、回転シャフトに取着されたゲートローラと、該ゲートローラと同軸に配設され、前記回転シャフトに取着された羽根車と、を備えた紙葉類集積繰出装置であって、前記羽根車は、前記回転シャフトに取着されたリング部と、該リング部の外周面から、前記紙葉類の集積時の前記回転シャフトの集積回転方向に倒れ込むように放射状に湾曲した複数の弾性羽根部と、該各弾性羽根部の間に配置された弾性支持部と、を有しており、前記弾性支持部は、前記紙葉類の繰出時の前記回転シャフトの繰出回転方向に倒れ込むように前記弾性羽根部を屈曲させたときに、前記弾性羽根部からの羽根車径方向に作用する荷重を支持するように弾性変形することを特徴とする。   A paper sheet stacking and feeding device according to the present invention includes a paper sheet stacking unit, a feed roller that performs stacking processing of the paper sheet on the stacking unit and processing of feeding the paper sheet from the stacking unit. And a gate roller disposed opposite to the feed roller and attached to the rotating shaft, and an impeller disposed coaxially with the gate roller and attached to the rotating shaft. A leaf stacking and feeding device, wherein the impeller includes a ring portion attached to the rotating shaft and an outer circumferential surface of the ring portion in a stacking rotation direction of the rotating shaft when the sheets are stacked. A plurality of elastic blade portions that are radially curved so as to fall down, and an elastic support portion disposed between the elastic blade portions, and the elastic support portion is provided when the paper sheets are fed out. The elastic blade portion so as to fall in the feeding rotation direction of the rotating shaft. When bent, characterized in that it elastically deforms to support a load applied to the impeller radially from the elastic blade portion.

本発明によれば、集積時に羽根車が回転したときに、弾性羽根部から羽根車径方向に作用する荷重を、弾性変形した弾性支持部が支持するので、集積された紙葉類を押さえ込まないように弾性羽根部の数を減らした場合であっても、低剛性紙葉類や折れ癖紙葉類等の悪条件の紙葉類に対しても紙葉類の剛性を確保することが可能なように変形させることができる。この結果、紙葉類の傾きにより不整列な状態で、紙葉類が集積された場合であっても、この状態を強制することができ、繰出処理の性能を向上させることもできる。また、羽根車の構造のみを変更するだけでよいので、小スペースで簡素な構造でかつ、低コストに集積及び繰出を実現することが可能である。   According to the present invention, when the impeller rotates during stacking, the elastic support portion that is elastically deformed supports the load acting in the radial direction of the impeller from the elastic blade portion, so that the stacked paper sheets are not pressed down. Even when the number of elastic blades is reduced, it is possible to ensure the rigidity of paper sheets against poorly conditioned paper sheets such as low-rigid paper sheets and folded paper sheets. It can be deformed as follows. As a result, even if the paper sheets are stacked in an unaligned state due to the inclination of the paper sheets, this state can be forced and the performance of the feeding process can be improved. Further, since only the structure of the impeller needs to be changed, it is possible to realize integration and feeding at a low cost with a simple structure in a small space.

Has been. The gate roller 40 is disposed so as to face the feed roller 30 and is attached to the rotating shaft 41 so as to be able to rotate in synchronization with the feed roller 30 during the accumulation process described later. On both sides of the gate roller 40, an impeller 50 that is disposed coaxially with the gate roller 40 and attached to the rotating shaft 41 is attached.

It is arranged so as to be swingable around the rotation axis. The stack guide 70 is configured to apply a pressing force to the upper surface of the paper sheet P3 on the rear plate 73 side in the accumulation space 71 by a stack guide spring (not shown).

さらに、ピックアップローラ６０は、集積部７の集積空間７１の上方に配置されており、集積部７に集積された紙葉類Ｐ３を繰出すためのローラであり、後述する集積部７の押板７４の上昇に伴って紙葉類Ｐ３に接触し、紙葉類Ｐ３を繰出すように構成されている。   Further, the pickup roller 60 is disposed above the accumulation space 71 of the accumulation unit 7 and is a roller for feeding out the paper sheets P3 accumulated in the accumulation unit 7. It is configured to come into contact with the paper sheet P3 as 74 rises and to feed out the paper sheet P3.

集積部７は、紙葉類Ｐを集積し収納するための集積空間７１が形成されており、該集積空間７１は、搬送ガイド１０ｂの下部、後板７３、及び、図示しない左右の側壁で囲われた空間である。また、集積部７の底部には、図示していない動力源により上下動する押板７４が配設されており、押板７４の上には、集積された紙葉類Ｐが積層状に収納される。   The stacking unit 7 is formed with a stacking space 71 for storing and storing paper sheets P. The stacking space 71 is surrounded by a lower portion of the conveyance guide 10b, a rear plate 73, and left and right side walls (not shown). It is a broken space. In addition, a push plate 74 that moves up and down by a power source (not shown) is disposed at the bottom of the stacking unit 7, and the stacked paper sheets P are stored in a stacked manner on the push plate 74. Is done.

ここで、図２に示す羽根車５０の詳細について以下に示す。羽根車５０は、上述したようにゲートローラ４０と同軸に配設され、回転シャフト４１と共に回転するように、回転シャフト４１に取着されている。   Here, the detail of the impeller 50 shown in FIG. 2 is shown below. The impeller 50 is disposed coaxially with the gate roller 40 as described above, and is attached to the rotating shaft 41 so as to rotate together with the rotating shaft 41.

羽根車５０は可撓性を有した材料であり、例えば、ゴム材、金属部材等の変形可能で弾性変形可能な材料からなる。この羽根車５０は、回転シャフト４１に取着されたリング部５１と、リング部５１の外周面５２から、紙葉類Ｐ２の集積時の回転シャフト４１の集積回転方向Ｒに倒れ込むように放射状に湾曲した複数（３つ）の弾性羽根部５３と、を有している。また、静止状態（非回転時）における羽根車５０の最外径は、ゲートローラ４０の外径と同等またはそれ以下である。さらに、羽根車５０は、各弾性羽根部５３，５３の間に配置された弾性支持部５４を有している。   The impeller 50 is a flexible material, and is made of a deformable and elastically deformable material such as a rubber material or a metal member, for example. The impeller 50 radiates from the ring portion 51 attached to the rotating shaft 41 and the outer peripheral surface 52 of the ring portion 51 so as to fall down in the stacking rotation direction R of the rotating shaft 41 when the sheets P2 are stacked. A plurality of (three) curved elastic blade portions 53. Further, the outermost diameter of the impeller 50 in a stationary state (when not rotating) is equal to or less than the outer diameter of the gate roller 40. Further, the impeller 50 has an elastic support portion 54 disposed between the elastic blade portions 53 and 53.

弾性支持部５４は、紙葉類Ｐ３の繰出時の回転シャフト４１の繰出回転方向Ｌに倒れ込むように弾性羽根部５３を屈曲させたときに、弾性羽根部５３の外側面からの羽根車５０の径方向ｒに作用する荷重を支持するように、Ｓ字状に弾性変形するように構成されている（図４参照）。   When the elastic blade portion 53 is bent so that the elastic support portion 54 falls in the feeding rotation direction L of the rotary shaft 41 when the paper sheet P3 is fed, the elastic support portion 54 of the impeller 50 from the outer surface of the elastic blade portion 53 It is configured to elastically deform in an S shape so as to support a load acting in the radial direction r (see FIG. 4).

具体的には、弾性支持部５４は、リング部５１の形状と、弾性羽根部５３の形状に沿って湾曲した湾曲部５４ａを有している。弾性羽根部５３，５３の間に配置された弾性支持部５４の湾曲部５４ａの一端５４ｂは、一方側の弾性羽根部５３の内側面の基端に隣接したリング部５１の外周面５２に連結され、湾曲部５４ａの他端５４ｃは、他方の弾性羽根部５３の外側面の基端部５３ｂに連結されている。なお、本実施形態でいう「基端部」とは、基端を含む部分であり、「先端部」とは、先端を含む部分をいう。   Specifically, the elastic support portion 54 includes a curved portion 54 a that is curved along the shape of the ring portion 51 and the shape of the elastic blade portion 53. One end 54b of the curved portion 54a of the elastic support portion 54 disposed between the elastic blade portions 53 and 53 is connected to the outer peripheral surface 52 of the ring portion 51 adjacent to the proximal end of the inner surface of the one elastic blade portion 53. The other end 54 c of the curved portion 54 a is connected to the base end portion 53 b on the outer surface of the other elastic blade portion 53. In the present embodiment, the “base end” refers to a portion including the base end, and the “tip end” refers to a portion including the tip.

このようにして、弾性支持部５４は、各弾性羽根部５３に対して、羽根車径方向ｒの内側に配置され、羽根車５０は、リング部５１の外周面５２の一部と、弾性支持部５４と、弾性羽根部５３の基端部５３ｂにより、ループ形状を形成することになる。   In this way, the elastic support portion 54 is disposed inside the impeller radial direction r with respect to each elastic blade portion 53, and the impeller 50 includes a part of the outer peripheral surface 52 of the ring portion 51 and the elastic support portion. A loop shape is formed by the portion 54 and the base end portion 53 b of the elastic blade portion 53.

このような紙葉類集積繰出装置１の作用を以下に示す。まず、図示していない装置外部の搬送部により紙葉類が１枚ずつ所定の間隔をもって、紙葉類集積繰出装置１の搬送ガイド１０ａ、１０ｂ間に形成された案内路２１に送られる。そして、紙葉類Ｐ２は、図示していない動力源により駆動されるフィードローラ３０、ゲートローラ４０、及びフィードローラ３０に当接して従動する搬送ローラ２０ａ、２０ｂによって集積空間７１内に進入する。   The operation of such a paper sheet stacking and feeding apparatus 1 will be described below. First, paper sheets are sent one by one to the guide path 21 formed between the transport guides 10a and 10b of the paper sheet stacking and feeding apparatus 1 at a predetermined interval by a transport unit (not shown) outside the apparatus. Then, the paper sheet P2 enters the accumulation space 71 by a feed roller 30 driven by a power source (not shown), a gate roller 40, and transport rollers 20a and 20b that are driven by contacting the feed roller 30.

羽根車５０は、ゲートローラ４０の回転シャフト４１とともに集積回転方向Ｒに回転する。羽根車５０の湾曲した弾性羽根部５３の先端部５３ａは、遠心力により、繰出回転方向Ｌに倒れ込むように屈曲し、羽根車５０は、放射状に径方向ｒに伸び広がり、回転直径φＤの軌跡を描く。   The impeller 50 rotates in the accumulation rotation direction R together with the rotation shaft 41 of the gate roller 40. The tip 53a of the curved elastic blade portion 53 of the impeller 50 is bent so as to fall down in the feeding rotation direction L due to centrifugal force, and the impeller 50 extends radially in the radial direction r and has a locus with a rotation diameter φD. Draw.

搬送ガイド１０ｂには、羽根車５０の回転奇跡に応じた位置に溝部が設けてあり、弾性羽根部５３の回転軌跡を阻害されることはない。集積空間７１内に進入する紙葉類Ｐ２は、遠心力により広がった羽根車５０の弾性羽根部５３により、上方向の力が作用し、スタックガイド７０間で変形する。この変形により紙葉類Ｐ２の剛性が増す。スタックガイド７０は、羽根車５０の弾性羽根部５３の回転軌跡に応じた位置に、切欠きが形成されており、弾性羽根部５３の回転軌跡を阻害しない構成が望ましい。   The conveyance guide 10b is provided with a groove portion at a position corresponding to the rotation miracle of the impeller 50, and the rotation locus of the elastic blade portion 53 is not obstructed. The paper sheet P2 entering the accumulation space 71 is deformed between the stack guides 70 due to an upward force acting by the elastic blade portion 53 of the impeller 50 spread by the centrifugal force. This deformation increases the rigidity of the paper sheet P2. It is desirable that the stack guide 70 has a notch formed at a position corresponding to the rotation trajectory of the elastic blade portion 53 of the impeller 50 and does not hinder the rotation trajectory of the elastic blade portion 53.

従来は、図１１に示すように羽根車８０により紙葉類Ｐ２に付与される変形力は、弾性羽根部８３が紙葉類Ｐ２に接触した状態で大きくなる。そのため、図１１に示す紙葉類集積繰出装置に比べて、弾性羽根部８３の個数が少ない羽根車８０を用いた紙葉類集積繰出装置では、弾性羽根部間において、紙葉類Ｐ２に付与する変形力の低下を招くことがある。   Conventionally, as shown in FIG. 11, the deformation force applied to the paper sheet P2 by the impeller 80 increases when the elastic blade part 83 is in contact with the paper sheet P2. Therefore, in the paper sheet stacking and feeding device using the impeller 80 having a smaller number of elastic blade portions 83 than the paper sheet stacking and feeding device shown in FIG. 11, the paper sheet P2 is provided between the elastic blade portions. The deformation force may be reduced.

しかし、本実施形態では、羽根車５０が、集積回転方向Ｒの回転により、紙葉類Ｐ２に接触した弾性羽根部５３と共に、弾性支持部５４も、静止時の位置から放射状に伸び広がるように持ち上げられる。そして、紙葉類Ｐ２の繰出時の回転シャフト４１の繰出回転方向Ｌに倒れ込むように（内側面が外側に向くように）弾性羽根部５３が屈曲し、一方の弾性羽根部５３の内側面に隣接したリング部５１の外周面５２に連結され、湾曲部５４ａの他端は、他方の弾性羽根部５３の基端部５３ｂに連結されているため、ループ形状が繰出回転方向Ｌに移動し、弾性支持部５４は、図３に示すように、Ｓ字状に湾曲し始める。   However, in the present embodiment, the impeller 50 is rotated in the stacking rotation direction R so that the elastic support portion 54 extends radially from the stationary position together with the elastic blade portion 53 in contact with the paper sheet P2. Lifted. Then, the elastic blade portion 53 is bent so that it falls in the feeding rotation direction L of the rotating shaft 41 when the paper sheet P2 is fed (the inner surface faces the outside), and the inner surface of one elastic blade portion 53 is bent. Since the other end of the curved portion 54 a is connected to the outer peripheral surface 52 of the adjacent ring portion 51 and the base end portion 53 b of the other elastic blade portion 53, the loop shape moves in the feeding rotation direction L, As shown in FIG. 3, the elastic support portion 54 starts to bend in an S shape.

さらに、羽根車５０が集積回転方向Ｒに回転すると、図４に示すように、弾性羽根部５３がさらに、繰出回転方向Ｌに倒れ込むように屈曲し、その内側面が紙葉類Ｐ２に接触すると共に、弾性支持部が、Ｓ字状に湾曲して弾性変形し、紙葉類Ｐ２と当接する弾性羽根部５３からの径方向ｒに作用する荷重を支持する構造（荷重に対して弾性支持部５４により復元力により反発可能な構造）となる。   Further, when the impeller 50 rotates in the accumulation rotation direction R, as shown in FIG. 4, the elastic blade portion 53 is further bent so as to fall down in the feeding rotation direction L, and the inner side surface thereof contacts the paper sheet P2. At the same time, the elastic support portion is curved in an S-shape and elastically deformed to support a load acting in the radial direction r from the elastic blade portion 53 that contacts the paper sheet P2 (elastic support portion against the load) 54, a structure that can be repelled by a restoring force).

このように、弾性羽根部５３が紙葉類Ｐ２に付与する変形力が低下し始める位相（回転位置）において、弾性支持部５４がＳ字状に弾性変形することで発生する弾性支持部５４の復元力により、たとえ弾性羽根部５３を減らしたとしても、紙葉類Ｐ２に付与する変形力の大きさを維持することができる。   Thus, in the phase (rotation position) where the deformation force applied to the paper sheet P2 by the elastic blade portion 53 starts to decrease, the elastic support portion 54 is generated by elastically deforming in an S shape. Even if the elastic blade portion 53 is reduced by the restoring force, the magnitude of the deformation force applied to the paper sheet P2 can be maintained.

更に、羽根車５０が回転すると、紙葉類Ｐ２に接触して変形力を付与していた弾性羽根部５３が、紙葉類Ｐ２の表面から離れるが、複数の弾性羽根部５３のうち、後続して接触する隣接した弾性羽根部５３が紙葉類Ｐ２に変形力を付与し始める。このように羽根車５０による紙葉類Ｐ２へ付与する変形力は、弾性羽根部５３，５３の間においても低減することが無く、一定以上の変形力を紙葉類Ｐ２に作用させることができる。   Further, when the impeller 50 rotates, the elastic blade portion 53 that has been applied with the deformation force by contacting the paper sheet P2 is separated from the surface of the paper sheet P2. Then, the adjacent elastic blades 53 that come into contact with each other begin to apply a deformation force to the paper sheet P2. Thus, the deformation force imparted to the paper sheet P2 by the impeller 50 is not reduced between the elastic blade portions 53 and 53, and a certain or greater deformation force can be applied to the paper sheet P2. .

そのため、紙葉類Ｐ２の剛性を低下させることなく紙葉類Ｐ２をスタックガイド７０に沿って集積空間７１内に導けるため、低剛性紙葉類やカール等折れ癖紙葉類においても先端部が垂れ下がることなく、集積された紙葉類Ｐ３との接触による障害を防止することができる可能な信頼性の高い集積性能を維持することができる。   For this reason, since the paper sheet P2 can be guided along the stack guide 70 into the accumulation space 71 without reducing the rigidity of the paper sheet P2, the leading end portion of the folded paper sheet such as a low-rigidity paper sheet or a curled sheet is also provided. Without drooping, it is possible to maintain a reliable and reliable accumulation performance that can prevent a failure due to contact with the accumulated paper sheets P3.

また、弾性羽根部５３の間における紙葉類Ｐ２への変形力を維持可能な羽根車５０は、弾性羽根部５３が３つ（三枚羽根）であっても、弾性支持部５４が弾性変形し、この変形による復元力によって、図１１に示す従来の四つ（四枚羽根）の羽根車８０と同等以上の変形力を発生することが可能である。   Further, in the impeller 50 capable of maintaining the deformation force to the paper sheet P2 between the elastic blade portions 53, the elastic support portion 54 is elastically deformed even if there are three elastic blade portions 53 (three blades). However, it is possible to generate a deformation force equal to or greater than that of the conventional four (four blades) impeller 80 shown in FIG.

また、図４及び５に示すように、従来のものに比べて、羽根車５０により弾性羽根部５３の枚数を削減することで、集積空間７１内の集積された紙葉類Ｐ３表面を、弾性羽根部５３で押さえない位相（回転位置）を作り出すことができる。   Also, as shown in FIGS. 4 and 5, the surface of the stacked paper sheets P3 in the stacking space 71 is elastically reduced by reducing the number of elastic blade portions 53 by the impeller 50 as compared with the conventional one. A phase (rotation position) that is not suppressed by the blade portion 53 can be created.

図５に示すように、集積された紙葉類Ｐ３の表面を押さえ付ける部材は、スタックガイド７０の先端部のみであり、特に集積された紙葉類Ｐ３の最上面の紙葉類Ｐ３は、集積空間７１内で移動し易い状態となる。   As shown in FIG. 5, the member that presses the surface of the accumulated paper sheet P3 is only the tip portion of the stack guide 70, and in particular, the uppermost paper sheet P3 of the accumulated paper sheet P3 is It becomes easy to move in the accumulation space 71.

スタックガイド７０は、紙葉類Ｐ２の進入により上方に持ち上げられるため、最上面の紙葉類Ｐ３を上部から押さえる部材がない瞬間ができる。このため、搬送部より１枚ずつ送られてくる紙葉類Ｐ１が偏り、傾き等の不整列の劣悪搬送条件の場合、図５に示すように紙葉類Ｐ２がフィードローラ３０とゲートローラ４０との挟持点を通過するまでは不整列状態で進入することになる。しかし、従来の紙葉類集積繰出装置（例えば図１３参照）の場合には、多数の弾性羽根部が形成された羽根車８０で集積処理を行うため、紙葉類Ｐ２を叩き落とすと同時に、紙葉類Ｐ２の上面を押さえ続けるために、紙葉類Ｐ２の不整列が修正され難い。   Since the stack guide 70 is lifted upward by the entry of the paper sheet P2, there is a moment when there is no member for pressing the uppermost paper sheet P3 from above. For this reason, when the paper sheets P1 sent one by one from the transport section are biased and in a poor transport condition such as an inclination or the like, the paper sheets P2 are fed into the feed roller 30 and the gate roller 40 as shown in FIG. It will enter in an unaligned state until it passes the pinching point. However, in the case of the conventional paper sheet stacking and feeding device (see, for example, FIG. 13), since the stacking process is performed by the impeller 80 in which a large number of elastic blade portions are formed, the paper sheet P2 is knocked down, In order to keep pressing the upper surface of the paper sheet P2, the misalignment of the paper sheet P2 is difficult to be corrected.

それに対して、図５に示す羽根車５０は、弾性羽根部５３が、従来のものに比べて少ないため、集積された紙葉類Ｐ３の上面を押さえない位相（回転位置）を確保できる。これにより、不整列紙葉類において整列性を向上するための外力を加えた場合に修正し易い状態を確保できる。   On the other hand, since the impeller 50 shown in FIG. 5 has fewer elastic blade portions 53 than the conventional one, it is possible to ensure a phase (rotational position) that does not press the upper surface of the stacked paper sheets P3. As a result, it is possible to secure a state in which correction is easy when an external force is applied to improve the alignment of the unaligned paper sheets.

以上、説明した動作により、図示しない搬送部より紙葉類集積繰出装置１に送られてくる紙葉類Ｐ１が、偏り傾き等の劣悪搬送条件で搬送された場合であっても、紙葉類Ｐ２の集積空間７１内への集積性能を向上させることができ、且つ集積空間７１内での紙葉類Ｐ３の整列性を向上させることができる。   As described above, even when the paper sheet P1 sent to the paper sheet stacking and feeding apparatus 1 from the transport unit (not shown) is transported under poor transport conditions such as a biased inclination, the paper sheet is transported. The accumulation performance of P2 in the accumulation space 71 can be improved, and the alignment of the paper sheets P3 in the accumulation space 71 can be improved.

次に、図６を用いて、紙葉類集積繰出装置１の繰出処理の動作について説明する。
集積処理から繰出処理に移行するには、ピックアップローラ６０、フィードローラ３０を所定の位相（回転位置）状態から、押板７４を図示しない動力により上方に移動する。押板７４は、積層状に集積した紙葉類Ｐ３とともに上方に移動し、紙葉類Ｐ３によってスタックガイド７０は回転支点を中心に、上方へと移動する。 Next, the operation of the feeding process of the paper sheet stacking and feeding device 1 will be described with reference to FIG.
In order to shift from the stacking process to the feeding process, the pickup roller 60 and the feed roller 30 are moved upward from a predetermined phase (rotation position) state by power (not shown). The push plate 74 moves upward together with the paper sheets P3 accumulated in a stack, and the paper sheet P3 moves the stack guide 70 upward about the rotation fulcrum.

紙葉類Ｐ３が、ピックアップローラ６０に接触し、図示しないばねで支持されるピックアップローラ６０と接触した状態で、上方に持ち上げられる。このときに、紙葉類Ｐ３の表面に作用する圧力は、ピックアップローラ６０のばね圧縮量より検知され、この検出された圧縮量により、押板７４の上昇を停止することができる。   The paper sheet P3 comes into contact with the pickup roller 60 and is lifted upward in a state of contact with the pickup roller 60 supported by a spring (not shown). At this time, the pressure acting on the surface of the paper sheet P3 is detected from the spring compression amount of the pickup roller 60, and the rise of the pressing plate 74 can be stopped by the detected compression amount.

この状態を繰出処理状態として、図示しないピックアップローラ６０、及びフィードローラ３０の動力を回転駆動することで、集積された複数の紙葉類Ｐ３の上部から１枚ずつ搬送部へ、紙葉類Ｐ３の繰出処理を行うことができる。   With this state as the feeding processing state, the power of the pick-up roller 60 and the feed roller 30 (not shown) is rotationally driven, so that the sheets P3 are fed one by one from the upper part of the plurality of stacked sheets P3 to the transport unit. The feeding process can be performed.

ここで、羽根車５０の弾性羽根部５３は、回転シャフト４１の集積回転方向Ｒに倒れ込むように放射状に湾曲し、さらに、弾性支持部５４も弾性羽根部の形状に沿って湾曲した湾曲しているので、羽根車５０をゲートローラ４０と共に、繰出回転方向Ｌに回転させた場合であっても、弾性羽根部５３及び弾性支持部５４は、リング部５１に巻き付くように作用する、又は、非回転時の折り畳んだ状態が維持される。すなわち、羽根車５０は、丸まった状態が維持され、ゲートローラ４０の径以下の状態となる。   Here, the elastic blade portion 53 of the impeller 50 is curved radially so as to fall in the accumulation rotation direction R of the rotary shaft 41, and the elastic support portion 54 is also curved along the shape of the elastic blade portion. Therefore, even when the impeller 50 is rotated together with the gate roller 40 in the feeding rotation direction L, the elastic blade portion 53 and the elastic support portion 54 act so as to be wound around the ring portion 51, or The folded state when not rotating is maintained. That is, the impeller 50 is maintained in a rounded state and is in a state equal to or smaller than the diameter of the gate roller 40.

従って、羽根車５０は繰出処理において、ゲートローラ４０とともに停止、または、繰出し方向（図６で時計方向）に回転した場合であっても、羽根車５０が繰出される紙葉類Ｐ３の搬送経路である案内路２１を塞いだり、紙葉類に搬送抵抗力を及ぼしたりすることがない。   Therefore, even if the impeller 50 is stopped together with the gate roller 40 in the feeding process or rotated in the feeding direction (clockwise in FIG. 6), the conveyance path of the paper sheet P3 through which the impeller 50 is fed. The guide path 21 is not blocked, and the conveyance resistance is not exerted on the paper sheets.

また、羽根車５０は、上述したようにループ形状が形成されているため、弾性羽根部５３及び弾性支持部５４は捩れ難い構造である。これにより、羽根車５０は、回転時の弾性羽根部５３同士の絡まりや捩れによる破断等に強く、従来のものに比べて高寿命となり、紙葉類集積繰出装置の信頼性を高めることができる。また、羽根車の構造のみを変更するだけでよいので、小スペースで簡素な構造でかつ、低コストに、集積処理及び繰出処理を実現することが可能である。   Further, since the impeller 50 has a loop shape as described above, the elastic blade portion 53 and the elastic support portion 54 have a structure that is difficult to twist. Accordingly, the impeller 50 is resistant to entanglement or twisting between the elastic blade portions 53 during rotation, has a longer life than the conventional one, and can improve the reliability of the paper sheet stacking and feeding device. . Further, since only the structure of the impeller needs to be changed, it is possible to realize the stacking process and the feeding process at a low cost with a simple structure in a small space.

〔第二実施形態〕
図７は、第二実施形態に係る紙葉類集積繰出装置の羽根車の側面図であり、紙葉類集積繰出装置の他の構成は、第一実施形態と同じ構成であるので、第二実施形態に係る紙葉類集積繰出装置の詳細な説明は省略する。 [Second Embodiment]
FIG. 7 is a side view of the impeller of the paper sheet stacking and feeding device according to the second embodiment, and the other configuration of the paper sheet stacking and feeding device is the same as that of the first embodiment. Detailed description of the paper sheet stacking and feeding apparatus according to the embodiment will be omitted.

図７に示すように、羽根車１５０は、回転シャフト４１に取着されたリング部１５１と、リング部１５１の外周面１５２から、紙葉類の集積時の回転シャフト４１の集積回転方向Ｒに倒れ込むように放射状に湾曲した複数（３つ）の弾性羽根部１５３を有している。さらに、羽根車１５０は、各弾性羽根部１５３，１５３の間に配置された弾性支持部１５４を有している。静止状態（非回転時）における羽根車１５０の最外径は、ゲートローラ４０の外径と同等またはそれ以下となっている。   As shown in FIG. 7, the impeller 150 includes a ring portion 151 attached to the rotating shaft 41 and an outer peripheral surface 152 of the ring portion 151 in the stacking rotation direction R of the rotating shaft 41 when sheets are stacked. A plurality (three) of elastic blade portions 153 that are radially curved so as to fall down are provided. Further, the impeller 150 has an elastic support portion 154 disposed between the elastic blade portions 153 and 153. The outermost diameter of the impeller 150 in a stationary state (when not rotating) is equal to or less than the outer diameter of the gate roller 40.

また、羽根車１５０は、紙葉類Ｐ３の繰出時の回転シャフト４１の繰出回転方向Ｌに倒れ込むように弾性羽根部１５３を屈曲させたときに、弾性羽根部１５３からの羽根車１５０の径方向ｒに作用する荷重を支持するように弾性変形するように構成されている。   Further, the impeller 150 is bent in the radial direction of the impeller 150 from the elastic blade portion 153 when the elastic blade portion 153 is bent so as to fall in the feeding rotation direction L of the rotary shaft 41 when the paper sheet P3 is fed. It is configured to elastically deform so as to support a load acting on r.

具体的には、弾性支持部１５４は、湾曲部１５４ａと、傾斜部１５４ｂを有している。湾曲部１５４ａは、弾性羽根部１５３及びリング部１５１の形状に沿って湾曲している。湾曲部１５４ａの一端は、弾性羽根部１５３の内側面の基端に隣接したリング部１５１の外周面に連結しており、他端が、傾斜部１５４ｂと連結している。傾斜部１５４ｂは、集積回転方向Ｒに倒れ込むように傾斜しており、弾性羽根部１５３を繰出回転方向Ｌに倒れ込むように屈曲させたときに、弾性羽根部１５３の基端部１５３ｂに当接する位置に形成されている。これにより、羽根車１５０には、弾性支持部１５４と、リング部１５１の一部により、ループ形状が形成される。   Specifically, the elastic support part 154 has a curved part 154a and an inclined part 154b. The curved portion 154 a is curved along the shape of the elastic blade portion 153 and the ring portion 151. One end of the curved portion 154a is connected to the outer peripheral surface of the ring portion 151 adjacent to the base end of the inner surface of the elastic blade portion 153, and the other end is connected to the inclined portion 154b. The inclined portion 154b is inclined so as to fall in the accumulation rotation direction R, and a position where the inclined portion 154b contacts the base end portion 153b of the elastic blade portion 153 when the elastic blade portion 153 is bent so as to fall in the feeding rotation direction L. Is formed. Thereby, a loop shape is formed in the impeller 150 by the elastic support portion 154 and a part of the ring portion 151.

このようにして、紙葉類集積繰出装置１は、集積回転方向Ｒの回転により、紙葉類Ｐ２に接触し湾曲した弾性羽根部１５３と共に、弾性支持部１５４も、静止時の位置から放射状に伸び広がるように持ち上げられる。羽根車１５０の湾曲した弾性羽根部１５３の先端部１５３ａは、遠心力により、繰出回転方向Ｌに倒れ込むように屈曲し、羽根車１５０は、放射状に径方向ｒに伸び広がる。   In this manner, the paper sheet stacking and feeding device 1 is configured so that the elastic support section 154 is also radially radiated from a stationary position together with the curved elastic blade section 153 that is in contact with the paper sheet P2 and curved by the rotation in the stacking rotation direction R. It can be lifted to stretch and spread. The tip 153a of the curved elastic blade portion 153 of the impeller 150 is bent so as to fall down in the feeding rotation direction L due to centrifugal force, and the impeller 150 extends radially in the radial direction r.

この動作に伴って、羽根車１５０は、集積回転方向Ｒの回転により、屈曲した弾性羽根部１５３の基端部１５３ｂに、弾性支持部１５４の傾斜部１５４ｂが当接し、弾性支持部１５４は、静止時の位置から放射状に伸び広がるように持ち上げられ、図３，４に示したのと同様に、Ｓ字に湾曲する。   Along with this operation, the impeller 150 is rotated in the accumulation rotation direction R, so that the inclined portion 154b of the elastic support portion 154 comes into contact with the base end portion 153b of the bent elastic blade portion 153, and the elastic support portion 154 is It is lifted so as to expand radially from the position at rest, and is curved into an S-shape as shown in FIGS.

そして、紙葉類Ｐ２の繰出時の回転シャフト４１の繰出回転方向Ｌに倒れ込むように弾性羽根部１５３が屈曲し、一方の弾性羽根部１５３に隣接したリング部１５１の外周面１５２に連結され、傾斜部１５４ｂが集積回転方向Ｒに倒れ込むように傾斜ているため、ループ形状が繰出回転方向Ｌに移動し、弾性支持部１５４は、図３に示すように、Ｓ字状に湾曲して弾性変形する。この弾性変形により、弾性支持部が、紙葉類Ｐ２と当接する弾性羽根部１５３からの径方向ｒに作用する荷重を支持する構造となる。   Then, the elastic blade portion 153 is bent so as to fall in the feeding rotation direction L of the rotating shaft 41 when the paper sheet P2 is fed, and is connected to the outer peripheral surface 152 of the ring portion 151 adjacent to the one elastic blade portion 153, Since the inclined portion 154b is inclined so as to fall in the accumulation rotation direction R, the loop shape moves in the feeding rotation direction L, and the elastic support portion 154 is elastically deformed by bending into an S shape as shown in FIG. To do. Due to this elastic deformation, the elastic support portion is configured to support a load acting in the radial direction r from the elastic blade portion 153 in contact with the paper sheet P2.

このようにして、第二実施形態に係る紙葉類集積繰出装置を用いた場合も、第一実施形態に係る紙葉類集積繰出装置と同様に、紙葉類Ｐ１が、偏り傾き等の劣悪搬送条件で搬送された場合であっても、紙葉類Ｐ２の集積空間７１内への集積性能を向上させることができ、且つ集積空間７１内での紙葉類Ｐ３の整列性を向上させることができる。また、羽根車１５０は繰出処理において、羽根車１５０が繰出される紙葉類Ｐ３の搬送経路である案内路２１を塞いだり、紙葉類に搬送抵抗力を及ぼしたりすることがない。このようにして、第一実施形態と同様の効果を達成することができる。   As described above, even when the paper sheet stacking and feeding device according to the second embodiment is used, the paper sheet P1 is inferior in bias inclination or the like as in the paper sheet stacking and feeding device according to the first embodiment. Even when transported under transport conditions, the stacking performance of the sheets P2 in the stacking space 71 can be improved, and the alignment of the sheets P3 in the stacking space 71 can be improved. Can do. Further, in the feeding process, the impeller 150 does not block the guide path 21 that is the transport path of the paper sheet P3 from which the impeller 150 is fed, and does not exert a transport resistance force on the paper sheet. In this way, the same effect as in the first embodiment can be achieved.

〔第三実施形態〕
図８は、第三実施形態に係る紙葉類集積繰出装置の羽根車の側面図であり、図９に示す紙葉類集積繰出装置の集積処理を説明するための図であり、図１０は、図９に示す紙葉類集積繰出装置の集積処理をさらに進めた図である。なお、紙葉類集積繰出装置の他の構成は、第一実施形態と同じ構成であるので、同じ符号を付して、第三実施形態に係る紙葉類集積繰出装置の詳細な説明は省略する。 [Third embodiment]
FIG. 8 is a side view of the impeller of the paper sheet stacking and feeding device according to the third embodiment, and is a diagram for explaining the stacking process of the paper sheet stacking and feeding device shown in FIG. FIG. 10 is a diagram in which the stacking process of the paper sheet stacking and feeding apparatus shown in FIG. 9 is further advanced. The other configurations of the paper sheet stacking and feeding apparatus are the same as those in the first embodiment, and thus the same reference numerals are given and detailed description of the paper sheet stacking and feeding apparatus according to the third embodiment is omitted. To do.

図８に示すように、羽根車２５０は、回転シャフト４１に取着されたリング部２５１と、リング部２５１の外周面２５２から、紙葉類の集積時の回転シャフト４１の集積回転方向Ｒに倒れ込むように放射状に湾曲した複数（３つ）の弾性羽根部２５３を有している。さらに、羽根車２５０は、各弾性羽根部２５３，２５３の間に配置された弾性支持部２５４を有している。静止状態（非回転時）における羽根車２５０の最外径は、ゲートローラ４０の外径と同等またはそれ以下となっている。   As shown in FIG. 8, the impeller 250 has a ring portion 251 attached to the rotary shaft 41 and an outer peripheral surface 252 of the ring portion 251 in the stacking rotation direction R of the rotary shaft 41 when sheets are stacked. A plurality (three) of elastic blade portions 253 that are radially curved so as to fall down are provided. Further, the impeller 250 has an elastic support portion 254 disposed between the elastic blade portions 253 and 253. The outermost diameter of the impeller 250 in a stationary state (when not rotating) is equal to or less than the outer diameter of the gate roller 40.

また、羽根車２５０は、紙葉類Ｐ３の繰出時の回転シャフト４１の繰出回転方向Ｌに倒れ込むように弾性羽根部２５３を屈曲させたときに、弾性羽根部２５３からの羽根車２５０の径方向ｒに作用する荷重を支持すべく弾性変形するように構成されている。   Further, the impeller 250 is bent in the radial direction of the impeller 250 from the elastic blade portion 253 when the elastic blade portion 253 is bent so as to fall in the feeding rotation direction L of the rotary shaft 41 when the paper sheet P3 is fed. It is configured to be elastically deformed to support a load acting on r.

具体的には、弾性支持部２５４は、湾曲部である短羽根部２５４ａからなり、短羽根部２５４ａは、弾性羽根部２５３との形状に沿って、集積回転方向Ｒに倒れ込むように放射状に湾曲しており、短羽根部２５４ａの基端２５４ｃは、リング部１５１の外周面に連結している。さらに、短羽根部２５４ａの基端２５４ｃから先端２５４ｄまでの曲線長が、弾性羽根部２５３の基端２５３ｃから先端２５３ｄまでの曲線長より短い。   Specifically, the elastic support portion 254 includes a short blade portion 254a that is a bending portion, and the short blade portion 254a is curved radially so as to fall in the accumulation rotation direction R along the shape of the elastic blade portion 253. The base end 254c of the short blade portion 254a is connected to the outer peripheral surface of the ring portion 151. Furthermore, the curve length from the base end 254c of the short blade | wing part 254a to the front-end | tip 254d is shorter than the curve length from the base end 253c of the elastic blade | wing part 253 to the front-end | tip 253d.

図９、１０を用いて、本実施形態に係る紙葉類集積繰出装置１Ａの羽根車２５０を用いた集積処理の動作を説明する。
図９に示すように、集積処理において、回転シャフト４１の集積回転方向の回転により羽根車２５０の弾性羽根部２５３及び弾性支持部（短羽根部）２５４は、遠心力により放射状に広がる。弾性羽根部２５３の回転軌跡は直径φＤ１の円周上にあり、短羽根部２５４ａの回転軌跡は、直径φＤ１よりも小さい直径φＤ２の円周上となる。 The operation of the stacking process using the impeller 250 of the paper sheet stacking and feeding apparatus 1A according to this embodiment will be described with reference to FIGS.
As shown in FIG. 9, in the accumulation process, the elastic blade portions 253 and the elastic support portions (short blade portions) 254 of the impeller 250 spread radially by centrifugal force due to the rotation of the rotating shaft 41 in the accumulation rotation direction. The rotation locus of the elastic blade portion 253 is on the circumference of the diameter φD1, and the rotation locus of the short blade portion 254a is on the circumference of the diameter φD2 smaller than the diameter φD1.

このとき、弾性羽根部２５３の回転軌跡は、紙葉類Ｐ３の上面に接触するような奇跡を描く。短羽根部２５４ａの回転軌跡は紙葉類Ｐ３に接触しない回転奇跡を描くような長さとなっている。このため、紙葉類Ｐ３を押さえ付けるのは弾性羽根部２５３のみである。   At this time, the rotation locus of the elastic blade portion 253 draws a miracle that comes into contact with the upper surface of the paper sheet P3. The rotation trajectory of the short blade portion 254a has such a length as to draw a rotation miracle that does not contact the paper sheet P3. For this reason, only the elastic blade portion 253 presses the paper sheet P3.

図１０に示すように、弾性羽根部２５３が少数の3つで構成される場合、集積された紙葉類Ｐ３の上面を押さえない位相（回転位置）を確保することができる。また、紙葉類Ｐ３に作用する上方に持ち上げる変形力は、図１０に示すように、弾性羽根部２５３の間で、弾性羽根部２５３と短羽根部２５４ａが重なることにより一定以上の変形力を維持でき、第一実施形態と同様の効果を達成することができる。   As shown in FIG. 10, when the elastic blade part 253 is composed of a small number of three, it is possible to ensure a phase (rotational position) that does not press the upper surface of the stacked paper sheets P3. Further, as shown in FIG. 10, the upwardly deforming force acting on the paper sheet P3 is such that the elastic blade portion 253 and the short blade portion 254a overlap each other between the elastic blade portions 253 so that the deformation force exceeds a certain level. It is possible to maintain the same effect as the first embodiment.

以上、本発明の実施の形態を図面を用いて詳述してきたが、具体的な構成はこの実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲における設計変更があっても、それらは本発明に含まれるものである。   As mentioned above, although embodiment of this invention has been explained in full detail using drawing, a concrete structure is not limited to this embodiment, Even if there is a design change in the range which does not deviate from the gist of the present invention. These are included in the present invention.

例えば、第一実施形態から第三実施形態に係る羽根車の各弾性羽根部は、等間隔に３箇所配置されているが、弾性羽根部の個数、配置位置（位相角）が異なっていてもよく、より遠心力を高めるために、弾性羽根部の先端部の羽根厚さが、他の部分に比べて厚くなっていてもよい。さらに、弾性羽根部及び弾性支持部は、前記機能を確保することができるのであれば、板状、棒状、又はワイヤ状の形状であってもよい。   For example, the elastic blade portions of the impeller according to the first embodiment to the third embodiment are arranged at three locations at equal intervals, but even if the number of elastic blade portions and the arrangement position (phase angle) are different. For better centrifugal force, the blade thickness at the tip of the elastic blade may be thicker than other portions. Furthermore, the elastic blade part and the elastic support part may be in a plate shape, a rod shape, or a wire shape as long as the function can be ensured.
