Description

本発明は紙幣等の紙葉に形成される角折れ片をシンプルな構成によって効率的に修正することができる紙葉の角折れ矯正装置、該装置による紙葉の角折れ矯正方法、及び紙葉取扱装置に関する。 According to the present invention, a paper leaf corner fold correction device capable of efficiently correcting corner folds formed on a paper leaf such as a banknote with a simple configuration, a method for correcting the corner fold of the paper leaf by the device, and a paper leaf. Regarding handling equipment.

多量の現金を取り扱う金融機関、電鉄駅、大規模小売店、テーマパーク、公営ギャンブル場等の各種施設では、紙幣の計数、仕分け、収納、払出し等の各種処理を自動化した紙幣取扱装置が設置されている。
角隅部に角折れがある紙幣は紙幣取扱装置内で紙詰まり等々の不具合を起こす原因となるため受け容れることができず、識別の段階でリジェクト処理して機外に排出し、角折れ部を平坦化してから装置に再投入することとなる。角折れ部を平坦化する処理を人手によって実施すると、処理枚数が多い場合に作業効率が低下する。このため、紙幣の角折れ部を自動的に平坦化する装置が種々開発されている。 At various facilities such as financial institutions that handle large amounts of cash, electric railway stations, large-scale retail stores, theme parks, and public gambling venues, banknote handling devices that automate various processes such as banknote counting, sorting, storage, and withdrawal are installed. ing.
Banknotes with broken corners cannot be accepted because they may cause problems such as paper jams in the bill handling device, so they are rejected at the identification stage and discharged to the outside of the machine. Will be flattened and then reinserted into the device. If the process of flattening the corner-folded portion is manually performed, the work efficiency is lowered when the number of processed sheets is large. For this reason, various devices have been developed that automatically flatten the corner-folded portion of the banknote.

特許文献１に係る紙幣修復装置は、複数本の修復棒の一端を傘の骨のように束ねると共に各修復棒の先端部で紙幣面上を摺動する際に角折れ部を引っ掛けるようにして開き平らに戻すことにより修復機能を発揮する構成が開示されている。
しかしながら、この構成では修正機能が紙幣の片面のみに作用する為、裏面へ折れ曲がった角折れ部を修復することができない。また、構成、及び動作が複雑であり、大型化、高コスト化を招くことが明らかである。
特許文献２に係る紙幣しわ伸し装置によれば、紙幣の搬送方向に向かって平面視で八の字型に拡開する形状のブラシ体、及びしわ伸ばしブロックが上下に接離自在に配置され、紙幣を両部材間で挟みながら搬送することにより搬送方向後端側の角折れ部が引き起こされるとともに、上下から挟む圧力で紙幣のしわが伸ばされる。
しかし、ブラシ体はしわ伸ばしブロックの上流側に配置されるため、ブラシ体のコシが強いと、しわ伸ばしされる前の紙幣の折れ跡を通過する際にブラシ体が搬送抵抗となり搬送紙幣の斜行や紙幣詰まりを引き起こす虞がある。一方、ブラシ体のコシが弱いと角折れ部を起こす効果が低下してしまう。また、ブラシ体は紙幣と接触して擦れる為、摩耗や変形など耐久性に懸念があり、このような条件を全て満たすブラシ体の選定は難しい。
特許文献３、及び特許文献４にも折れ曲がり部を修正するための構成が開示されているが、何れも部品点数の増加、大型化、高コスト化という不具合がある。 In the banknote repair device according to Patent Document 1, one end of a plurality of repair rods is bundled like an umbrella bone, and a corner fold portion is hooked when sliding on the banknote surface at the tip of each repair rod. A configuration that exerts a repair function by opening and flattening is disclosed.
However, in this configuration, since the correction function acts on only one side of the bill, it is not possible to repair the corner fold that is bent to the back side. In addition, it is clear that the configuration and operation are complicated, leading to an increase in size and cost.
According to the banknote wrinkle smoothing device according to Patent Document 2, a brush body having a shape that expands in a figure eight shape in a plan view in the direction of transporting banknotes and a wrinkle smoothing block are arranged vertically and detachably. By transporting the bill while sandwiching it between the two members, a corner fold portion on the rear end side in the transport direction is caused, and the wrinkles of the bill are smoothed by the pressure of sandwiching the bill from above and below.
However, since the brush body is arranged on the upstream side of the wrinkle smoothing block, if the brush body is strong, the brush body becomes a transport resistance when passing through the creases of the bill before the wrinkle smoothing, and the transport bill is slanted. May cause line or banknote jams. On the other hand, if the brush body is weak, the effect of causing corner breaks is reduced. In addition, since the brush body comes into contact with the banknote and rubs against it, there is a concern about durability such as wear and deformation, and it is difficult to select a brush body that satisfies all of these conditions.
Patent Document 3 and Patent Document 4 also disclose a configuration for correcting a bent portion, but both have problems such as an increase in the number of parts, an increase in size, and an increase in cost.

It is characterized by a configuration including a corner fold correction portion provided in (including).
In the following embodiment, a device for correcting corner folds (corner folds) formed on a banknote as an example of a paper sheet will be described.
Here, the corner-folded portion is a triangular portion formed by folding the corners of a banknote, which should be originally flat, to one side. Straightening is synonymous with straightening and flattening, and straightening a corner fold means that once it is raised, it is flattened to almost the same level as other flat parts of the bill.
In the following description, the front end and the rear end of the bill are based on the normal transport direction of the bill. Further, regarding the front surface and the back surface of the banknote, the posture of the banknote at the time of the first introduction to the corner fold straightening device is used as a reference.

＜第一実施形態＞
図１（ａ）、（ｂ）は、本発明の第一実施形態に係る紙幣の角折れ矯正装置の外観斜視図である。図２（ａ）はその正面図、（ｂ）はその部分拡大正面図、図３はその平面図、図４はその下面図である。
この実施形態に係る紙幣の角折れ矯正装置１では、第一湾曲搬送ガイド部材が、並行に配置された三個の円筒状（又は円柱状）の回転自在なローラであり、ローラを正逆回転駆動することにより紙幣を正方向と逆方向の双方向に往復搬送するようにしている。

ここで、全てのローラ１０、２０、３０が同形状である必要はない。また、３つのローラのうちの少なくとも一個を回転しない第一湾曲搬送ガイド部材としてもよい。更に、ローラに代えて固定された（非回転の）第一湾曲搬送ガイド部材としてもよい（第四実施形態参照）。 <First Embodiment>
1A and 1B are external perspective views of a banknote corner fold straightening device according to the first embodiment of the present invention. FIG. 2A is a front view thereof, FIG. 2B is a partially enlarged front view thereof, FIG. 3 is a plan view thereof, and FIG. 4 is a bottom view thereof.
In the banknote corner bending straightening device 1 according to this embodiment, the first curved transport guide member is three cylindrical (or cylindrical) rotatable rollers arranged in parallel, and the rollers are rotated in the forward and reverse directions. By driving, the banknotes are reciprocated in both the forward and reverse directions.
In the corner fold correction device 1, one side or the other side (that is, one side) of the bills to be transported in parallel and adjacent to each other by arranging the rotation shafts 10a, 20a, 30a extending in the direction orthogonal to the bill transport direction A in parallel. Three cylindrical rollers of the same shape (first curved transport guide member: inner diameter side curved guide member, transport means) 10, 20, 30 in contact with any surface) and the outer peripheral surface (curved guide convex surface) of each roller. ), An outer guide member having a curved guide concave surface that guides the other surface or one surface of the bill while forming curved paths (curved transport paths) G1, G2, and G3 for guiding the passage of the bill. (Second curved transport guide member: curved guide member on the outer diameter side) 50, 60, 70 and corner break correction portions (edge portions) provided at one end edges of the outer guide members 50, 70 located at both ends in the transport direction. The 51a and 71a, the corner bending straightening portions (edge portions) 61a and 61b provided at both ends of the central outer guide member 60 in the transport direction, and the rollers 10, 20 and 30 in the positive direction indicated by the arrow A (introduction of bills). Direction) and forward / reverse switching in the opposite direction indicated by arrow B. A driving means for reciprocating the bill in the curved path in both the forward and reverse directions, and a control means for controlling the driving means. The provided configuration is characteristic.
Here, it is not necessary that all the rollers 10, 20 and 30 have the same shape. Further, at least one of the three rollers may be used as the first curved transport guide member that does not rotate. Further, instead of the rollers, a fixed (non-rotating) first curved transport guide member may be used (see the fourth embodiment).

補助ローラ１２、２２、３２は各外側ガイド部材５０、６０、７０の適所（本例では幅方向中央部）に形成した開口を介して湾曲路内の紙幣の外側面と接しつつ回転することにより紙幣の搬送をサポートする手段である。補助ローラ１２、２２、３２は、搬送方向の少なくとも２箇所において一枚の紙幣の少なくとも２箇所をローラ１０、２０、３０との間で挟持できる位置に配置される。
本例では角折れ矯正部５１ａ、７１ａは、湾曲路Ｇ１、Ｇ３の搬送方向一端部に相当する外側ガイド部材５０、７０の一端縁（搬送方向の外側端縁）に設けられ、角折れ矯正部６１ａ、６１ｂは湾曲路Ｇ２の搬送方向両端部に相当する外側ガイド部材６０の両端縁（搬送方向の両端縁）に設けられている。角折れ矯正部５１ａ、６１ａ、６１ｂ、７１ａは、遊端側へ向かう程、平面視の幅がテーパー状（ハ字状）に漸減する。このため、紙幣の先端又は後端の角折れ片が外部から各湾曲路Ｇ１、Ｇ２、Ｇ３内に進入する際に各角折れ片が傾斜して延びる角折れ矯正部に引っ掛かって徐々に引き起こされ、その後ローラ外周面（湾曲案内凸面）と外側ガイド部材の湾曲案内凹面との間で加圧されつつ姿勢矯正されて平坦化される。このように紙幣を一方向に搬送して湾曲路内に進入させ、後端部が角折れ矯正部を通過することにより紙幣後端部の角折れ片の矯正が行われる。 The auxiliary rollers 12, 22, and 32 rotate while being in contact with the outer surface of the banknote in the curved path through the openings formed at appropriate positions (in this example, the central portion in the width direction) of the outer guide members 50, 60, and 70. It is a means to support the transportation of banknotes. The auxiliary rollers 12, 22 and 32 are arranged at at least two locations in the transport direction so that at least two locations of one bill can be sandwiched between the rollers 10, 20 and 30.
In this example, the corner fold correction portions 51a and 71a are provided on one end edges (outer end edges in the transport direction) of the outer guide members 50 and 70 corresponding to one end portions in the transport direction of the curved paths G1 and G3, and the corner fold correction portions 51a and 71a are provided. 61a and 61b are provided at both end edges (both end edges in the transport direction) of the outer guide member 60 corresponding to both end portions in the transport direction of the curved road G2. The width of the corner fold correction portions 51a, 61a, 61b, 71a gradually decreases in a tapered shape (C shape) toward the free end side. For this reason, when the corner folds at the front end or the rear end of the bill enter the curved paths G1, G2, and G3 from the outside, the corner folds are caught by the angle fold correction portion extending in an inclined manner and are gradually caused. After that, the posture is corrected and flattened while being pressurized between the outer peripheral surface of the roller (convex curved guide surface) and the concave curved guide surface of the outer guide member. In this way, the banknote is conveyed in one direction and entered into the curved path, and the rear end portion passes through the corner fold correction portion to correct the corner fold piece at the rear end portion of the bill.

先端及び後端側の表面及び裏面側に夫々折れた角折れ片１０１、１０２、１０３、１０４がある紙幣１００を矯正する場合には、まず図１（ａ）のように一方向Ａから湾曲路Ｇ１内に紙幣１００を進入させるために制御手段は駆動手段を制御して各ローラ１０、２０、３０を矢印Ａ方向に同速度で（或いは、必要に応じて適度な速度差をもって）回転駆動する。
矢印Ａ方向へ搬送される紙幣１００が湾曲路Ｇ１、Ｇ２、Ｇ３内を進行する過程では図１（ｂ）に示す先端側の角折れ片１０１、１０２は何れの角折れ矯正部５１ａ、６１ａ、６１ｂ、７１ａによっても矯正を受けず、紙幣１００の後端側、且つ表側にある角折れ片１０３が、紙幣１００が湾曲路Ｇ１内を方向Ａに移動して角折れ矯正部５１ａを通過する際に矯正を受ける。
紙幣の先端側、且つ表側の角折れ片１０１を矯正するには、先端側の角折れ片が他方の角折れ矯正部７１ａをＡ方向へ一旦完全離脱した後に各ローラをＢ方向に逆回転させて紙幣をＢ方向へ逆搬送させる（図１（ｂ））。逆搬送される過程で先端側の角折れ片１０１が他方の角折れ矯正部７１ａを通過する際に矯正が行われる。
なお、先端側、且つ表側の角折れ片１０１の形状、サイズが充分に大きく、修正し易い等の状況によっては、第一湾曲路Ｇ１内に方向Ａから進入する際に角折れ矯正部５１ａによって矯正することも可能であるが、矯正を確実にするのは上記の逆搬送によって角折れ矯正部７１ａを利用して行う矯正である。 When correcting a banknote 100 having square-folded pieces 101, 102, 103, 104 that are folded on the front surface and the back surface side of the front end and the rear end side, respectively, as shown in FIG. 1A, a curved path is first formed from one direction A. In order to allow the bill 100 to enter the G1, the control means controls the drive means to rotate and drive the rollers 10, 20, and 30 in the direction of arrow A at the same speed (or, if necessary, with an appropriate speed difference). ..
In the process in which the banknote 100 transported in the direction of arrow A travels in the curved paths G1, G2, and G3, the corner fold pieces 101 and 102 on the tip side shown in FIG. 1 (b) are any of the corner fold correction portions 51a and 61a. When the corner fold piece 103 on the rear end side and the front side of the bill 100 is not corrected by 61b and 71a and the bill 100 moves in the curved path G1 in the direction A and passes through the corner fold correction portion 51a. Get corrected.
In order to correct the corner folds 101 on the tip side and the front side of the banknote, the corner fold pieces on the tip side completely separate the other corner fold correction portion 71a in the A direction, and then each roller is rotated in the reverse direction in the B direction. The banknotes are reversely conveyed in the B direction (FIG. 1 (b)). In the process of reverse transportation, correction is performed when the corner fold piece 101 on the tip side passes through the other corner fold correction portion 71a.
Depending on the shape and size of the corner fold piece 101 on the tip side and the front side, which is easy to correct, the corner fold correction portion 51a may be used when entering the first curved path G1 from the direction A. Although it is possible to correct the correction, it is the correction performed by using the corner fold correction portion 71a by the above-mentioned reverse transport to ensure the correction.

紙幣１００の裏側へ折れた角折れ片１０２、１０４を矯正するのは、外側ガイド部材６０の角折れ矯正部６１ａ、６１ｂの役割である。即ち、紙幣１００が第二湾曲路Ｇ２内を図２の右側からＡ方向へ進行する際には、後端部の裏側にある角折れ片１０４が図２（ｂ）に示すように角折れ矯正部６１ａの矯正作用によって起立後、平坦化される。紙幣１００が第二湾曲路Ｇ２内をＢ方向へ進行する際には、先端部の裏側にある角折れ片１０２が角折れ矯正部６１ｂの矯正作用によって起立後、平坦化される。 It is the role of the corner fold straightening portions 61a and 61b of the outer guide member 60 to correct the corner fold pieces 102 and 104 that are folded to the back side of the bill 100. That is, when the bill 100 travels in the second curved path G2 from the right side of FIG. 2 in the A direction, the corner fold piece 104 on the back side of the rear end portion corrects the corner fold as shown in FIG. 2 (b). After standing up by the corrective action of the portion 61a, it is flattened. When the bill 100 travels in the second curved path G2 in the B direction, the corner fold piece 102 on the back side of the tip portion stands up and is flattened by the straightening action of the corner fold correction portion 61b.

図２（ａ）に示すように、各外側ガイド部材５０、７０は、紙幣を導入する側の端部がローラ１０、３０周面との間に形成する間隔が遊端側に向かうにつれてテーパー状（或いは湾曲状）に漸増するように構成されており、このため紙幣端縁を湾曲路内に導入し易くなっている。
中央の外側ガイド部材６０は、搬送方向両端部（角折れ矯正部６１ａ、６１ｂの形成部位）がローラ周面からテーパー状に離間しているため、往復搬送時における紙幣端縁の湾曲路内への進入が容易となっている。また、表側の角折れ片を矯正する際に大きな負荷を与えてダメージを与えることなくスムーズに矯正することができる。
外側ガイド部材５０、７０の各端縁に位置する角折れ矯正部５１ａ、７１ａは、図２（ａ）に示すように徐々にローラ周面から離間するように構成されているため、紙幣の角折れ片が各角折れ矯正部５１ａ、７１ａを通過する際に大きな負荷を与えてダメージを与えることなくスムーズに矯正することができる。 As shown in FIG. 2A, each of the outer guide members 50 and 70 has a tapered shape as the distance formed by the end portion on the side where the bills are introduced between the peripheral surfaces of the rollers 10 and 30 is toward the free end side. It is configured to gradually increase (or curved), which facilitates the introduction of the banknote edge into the curved path.
Since both ends of the outer guide member 60 in the center in the transport direction (the forming portions of the corner bending straightening portions 61a and 61b) are separated from the peripheral surface of the roller in a tapered shape, the outer guide member 60 enters the curved path of the banknote edge during reciprocating transport. Is easy to enter. In addition, when correcting the corner folds on the front side, a large load can be applied to smoothly correct the broken pieces without causing damage.
Since the corner bending straightening portions 51a and 71a located at the respective end edges of the outer guide members 50 and 70 are configured to gradually separate from the roller peripheral surface as shown in FIG. 2A, the corners of the banknote When the broken piece passes through the corner bending straightening portions 51a and 71a, it can be smoothly straightened without giving a large load and damaging it.

本例ではローラを３個併設して各湾曲路Ｇ１、Ｇ２、Ｇ３から成る搬送経路が全体としてＳ字状になっているため、紙幣をＳ字状の経路に沿って湾曲させながら往復搬送することにより表裏全ての角折れ片を他の紙幣部位から離間させる（引き起こす）ことが可能となり、角折れ矯正部による角折れ片の引っ掛け、掬い上げ、引き起こしが確実となり、全体として矯正が確実となる。
なお、何れの外側ガイド部材５０、６０、７０も軸５３、６３、７３を中心として回動することにより湾曲案内凹面をローラ周面から離間させて、湾曲路の少なくとも搬送方向の各端部側を開放できるように構成されている。
本例ではローラを３個併設したため、湾曲路Ｇ１、Ｇ２、Ｇ３から成る搬送経路は全体としてＳ字状になっているが、これは一例に過ぎず、ローラの数、搬送経路の形状は種々変形が可能である。 In this example, three rollers are arranged side by side and the transport path consisting of the curved paths G1, G2, and G3 is S-shaped as a whole, so that the banknotes are reciprocally transported while being curved along the S-shaped path. As a result, it is possible to separate (cause) all the front and back corner folds from other bill parts, and the corner fold correction part ensures that the corner folds are caught, scooped up, and raised, and the correction is assured as a whole. ..
It should be noted that any of the outer guide members 50, 60, 70 is rotated around the shafts 53, 63, 73 to separate the curved guide concave surface from the roller peripheral surface, and at least each end side of the curved path in the transport direction. Is configured to be open.
In this example, since three rollers are installed side by side, the transport path consisting of curved paths G1, G2, and G3 is S-shaped as a whole, but this is only an example, and the number of rollers and the shape of the transport path vary. It can be transformed.

また、テーパー状のエッジ部から成る角折れ矯正部５１ａ、６１ａ、６１ｂ、７１ａを夫々構成する、各外側ガイド部材５０、６０、７０の幅方向両端の２つのエッジ部が直線状に延びる構成例を示したが、内側へ凹状に湾曲して延びるエッジ部、或いは外側に凸状に湾曲して延びるエッジ部（図８参照）としてもよい。 Further, a configuration example in which the two edge portions at both ends in the width direction of the outer guide members 50, 60, and 70, each of which constitutes the corner bending straightening portions 51a, 61a, 61b, and 71a having tapered edge portions, extend linearly. However, the edge portion extending inwardly curved in a concave shape or the edge portion extending outward in a convex shape (see FIG. 8) may be used.

第一実施形態に係る紙幣の角折れ矯正装置によれば、紙幣をＳ字状に湾曲した搬送経路に沿って搬送するので、一回の往復搬送により、紙幣の両端に位置する表裏両面の角折れ片をローラ周面から離間する方向へ起こすことが可能である。つまり、紙幣本体の一面がローラの外周面（湾曲案内凸面）と接触しつつ外周面に沿って湾曲した状態に変形させられることにより、紙幣の他面側に形成された角折れ片は起立方向、即ちローラ外周面から離間する方向へ起き上がり易くなる。この作用によって、紙幣本体から起立方向に変形した角折れ片をテーパー状のエッジ部から成る角折れ矯正部５１ａ、６１ａ、６１ｂ、７１ａが確実に引っ掛けることが可能となり、角折れ片を平坦に修正できる。
本実施形態に係る角折れ矯正装置１は、部品点数が少なく、構成がシンプルであるため、小型化、簡易構造化、低コスト化が可能でありながら、表裏両面の全ての角折れ片を矯正することができる。 According to the corner fold correction device for banknotes according to the first embodiment, the banknotes are transported along an S-shaped curved transport path, so that the corners on both the front and back sides located at both ends of the banknote can be transported by one reciprocating transport. It is possible to raise the broken piece in a direction away from the peripheral surface of the roller. That is, one side of the bill body is deformed into a curved state along the outer peripheral surface while being in contact with the outer peripheral surface (curved guide convex surface) of the roller, so that the corner-folded pieces formed on the other side of the bill are in the upright direction. That is, it becomes easy to get up in the direction away from the outer peripheral surface of the roller. By this action, the corner fold straightening portions 51a, 61a, 61b, 71a formed of tapered edge portions can surely hook the corner fold pieces deformed in the upright direction from the bill body, and the corner fold pieces are corrected flat. it can.
The corner fold straightening device 1 according to the present embodiment has a small number of parts and a simple structure, so that it is possible to reduce the size, simple structure, and cost, and correct all the corner folds on both the front and back sides. can do.

Allows the passage of banknotes between two cylindrical rollers (first curved transport guide member, transport means) 10 and 30 having the same shape in contact with the surface) and the outer peripheral surface (curved guide convex surface) of each roller. Outer guide members 50 and 70 having curved guide concave surfaces for guiding the other surface or one surface of the bill while forming curved paths (curved transport paths) G1 and G3 for guides, and outer guide members 50 and 70, respectively. The corner bending straightening portions (edge portions) 51a, 51b, 71a, 71b provided at both ends and the rollers 10 and 30 are driven to switch forward and reverse in the forward direction indicated by the arrow A and the reverse direction indicated by the arrow B. It is characterized by a configuration including a driving means for reciprocating and transporting banknotes in a curved road and a control means for controlling the driving means.

補助ローラ１２、３２は各外側ガイド部材５０、７０の適所（本例では幅方向中央部）に形成した開口を介して湾曲路内の紙幣の外側面と接しつつ回転することにより紙幣の搬送をサポートする手段である。
角折れ矯正部５１ａ、５１ｂ、７１ａ、７１ｂは、湾曲路Ｇ１、Ｇ３の搬送方向両端部に相当する外側ガイド部材５０、７０の両端部に夫々設けられている。角折れ矯正部（エッジ）５１ａ、５１ｂ、７１ａ、７１ｂは、遊端側へ向かう程、平面視の幅がテーパー状（ハ字状）に漸減する。本例において各外側ガイド部材５０、７０は、角折れ矯正部５１ｂ、７１ｂの幅方向中間部側端縁から搬送方向に沿って延在する受け渡しガイド部５２、７２を有している。受け渡しガイド部５２、７２は紙幣の通過を許容するガイド用の受け渡し搬送路Ｇ４を形成しており、湾曲路Ｇ１、Ｇ３間での紙幣１００のスムーズな受け渡しを可能としている。 The auxiliary rollers 12 and 32 rotate while being in contact with the outer surface of the banknote in the curved path through an opening formed at an appropriate position (central portion in the width direction in this example) of each of the outer guide members 50 and 70 to convey the banknote. It is a means to support.
The corner break correction portions 51a, 51b, 71a, 71b are provided at both ends of the outer guide members 50, 70 corresponding to both ends of the curved paths G1 and G3 in the transport direction, respectively. The width of the corner break correction portions (edges) 51a, 51b, 71a, 71b gradually decreases in a tapered shape (C-shape) toward the free end side. In this example, the outer guide members 50 and 70 have transfer guide portions 52 and 72 extending along the transport direction from the widthwise intermediate portion side edge of the corner bending straightening portions 51b and 71b. The delivery guide units 52 and 72 form a delivery transfer path G4 for a guide that allows the passage of banknotes, and enables smooth delivery of the banknote 100 between the curved paths G1 and G3.

図７（ａ）〜（ｄ）は、紙幣の角折れ矯正の様子を模式的に示す部分拡大正面図である。なお、紙幣１００の先端・後端及び表裏については、紙幣を湾曲路Ｇ１へ方向Ａに導入した時を基準として記載する。
図７（ａ）に示すように、紙幣１００が湾曲路Ｇ１の外側、即ち方向Ａから湾曲路Ｇ１内に進入する際に紙幣１００の搬送方向後端、且つ表側に位置する角折れ片１０３が傾斜して延びる角折れ矯正部５１ａに引っ掛かって徐々に引き起こされ、その後ローラ１０外周面（湾曲案内凸面）と外側ガイド部材５０の湾曲案内凹面との間で加圧されつつ姿勢矯正されて平坦化される。このように紙幣１００を一方向に搬送して湾曲路Ｇ１内に進入させ、後端部が角折れ矯正部５１ａを通過することにより紙幣後端部の角折れ片１０３の矯正が行われる。
図７（ｂ）に示すように、紙幣１００の先端、且つ表側にある角折れ片１０１は、紙幣１００の先端部が湾曲路Ｇ１内を方向Ａに移動して、一旦角折れ矯正部５１ｂを通過してから逆方向に戻り方向Ｂに搬送される際に各角折れ矯正部５１ｂによって姿勢矯正される。 7 (a) to 7 (d) are partially enlarged front views schematically showing a state of correction of corner folds of banknotes. The front and rear ends and the front and back ends of the bill 100 are described with reference to the time when the bill is introduced into the curved path G1 in the direction A.
As shown in FIG. 7A, when the bill 100 enters the curved road G1 from the outside of the curved road G1, that is, the corner folded piece 103 located at the rear end in the transport direction of the bill 100 and on the front side when entering the curved road G1 from the direction A. It is gradually caused by being caught by the angle bending straightening portion 51a extending in an inclined manner, and then the posture is corrected and flattened while being pressurized between the outer peripheral surface of the roller 10 (curved guide convex surface) and the curved guide concave surface of the outer guide member 50. Will be done. In this way, the banknote 100 is conveyed in one direction and entered into the curved path G1, and the rear end portion passes through the corner fold straightening portion 51a to correct the corner fold piece 103 at the rear end portion of the bill.
As shown in FIG. 7B, the tip of the bill 100 and the corner fold piece 101 on the front side move the tip of the bill 100 in the curved path G1 in the direction A, and once the corner fold correction portion 51b is formed. After passing through, the posture is corrected by each corner bending correction portion 51b when it is conveyed in the reverse direction and the return direction B.

図７（ｃ）に示すように、紙幣の後端、且つ裏側へ折れた角折れ片１０４を矯正するのは、中央の角折れ矯正部７１ｂの役割である。即ち、第一湾曲路Ｇ１を経由して第三湾曲路Ｇ３内をＡ方向に進行する紙幣１００の後端部が角折れ矯正部７１ｂをＡ方向へ通過する際に、角折れ片１０４が角折れ矯正部７１ｂの矯正作用によって起立後、平坦化される。
図７（ｄ）に示すように、紙幣の先端、且つ裏側へ折れた角折れ片１０２を矯正するのは、角折れ矯正部７１ａの役割である。即ち、第一湾曲路Ｇ１を経由して第三湾曲路Ｇ３内をＡ方向に進行する紙幣１００の先端部が、角折れ矯正部７１ａをＡ方向へ通過してからＢ方向に逆搬送される際に、角折れ片１０２が角折れ矯正部７１ａの矯正作用によって起立後、平坦化される。 As shown in FIG. 7C, it is the role of the central corner fold correction portion 71b to correct the corner fold piece 104 that is folded toward the rear end and the back side of the banknote. That is, when the rear end portion of the bill 100 traveling in the A direction in the third curved road G3 via the first curved road G1 passes through the corner bending correction portion 71b in the A direction, the corner bent piece 104 is cornered. After standing up by the straightening action of the break straightening portion 71b, it is flattened.
As shown in FIG. 7D, it is the role of the corner fold straightening portion 71a to correct the corner fold piece 102 that is folded toward the front end and the back side of the banknote. That is, the tip of the bill 100 traveling in the A direction in the third curved road G3 via the first curved road G1 passes through the corner bending straightening portion 71a in the A direction and then is reversely conveyed in the B direction. At that time, the corner fold piece 102 is flattened after standing up by the straightening action of the corner fold correction portion 71a.

図６に示すように、各外側ガイド部材５０、７０の紙幣を導入する側の端部（角折れ矯正部５１ａ、７１ａの形成部位）とローラ周面との間隔がテーパー状（或いは湾曲状）に漸増するように構成すれば、紙幣端縁を湾曲路内に導入し易くなる。また、角折れ片を矯正する際に大きな負荷を与えてダメージを与えることなくスムーズに矯正することができる。
本例ではローラを２個併設して各湾曲路Ｇ１、Ｇ３から成る搬送経路が全体としてＳ字状の湾曲経路になっているため、紙幣をＳ字状の経路に沿って湾曲させながら往復搬送することにより表裏全ての角折れ片を他の紙幣部位から離間させる（引き起こす）ことが可能となり、角折れ矯正部５１ａ、５１ｂ、７１ａ、７１ｂによる角折れ片の引っ掛け、掬い上げ、引き起こしが確実となり、全体として矯正が確実となる。 As shown in FIG. 6, the distance between the end portion of each of the outer guide members 50 and 70 on the side where the banknotes are introduced (the forming portion of the corner bending straightening portions 51a and 71a) and the peripheral surface of the roller is tapered (or curved). If it is configured so as to gradually increase in number, it becomes easy to introduce the edge of the bill into the curved path. In addition, when straightening a broken piece, a large load is applied and the broken piece can be straightened smoothly without damaging it.
In this example, two rollers are installed side by side and the transport path consisting of the curved paths G1 and G3 is an S-shaped curved path as a whole. Therefore, the banknote is reciprocally transported while being curved along the S-shaped path. By doing so, it is possible to separate (cause) all the front and back corner folds from other bill parts, and the corner fold correction portions 51a, 51b, 71a, 71b can surely catch, scoop up, and raise the corner folds. , The correction is certain as a whole.

本例ではローラを２個併設したため、湾曲路Ｇ１、Ｇ３から成る搬送経路は全体としてＳ字状になっているが、これは一例に過ぎず、ローラの数、搬送経路の形状は種々変形が可能である。
また、テーパー状のエッジ部から成る角折れ矯正部５１ａ、５１ｂ、７１ａ、７１ｂが直線状に延びる構成例を示したが、内側へ凹状に湾曲して延びるエッジ部、或いは外側に凸状に湾曲して延びるエッジ部としてもよい。 In this example, since two rollers are installed side by side, the transport path consisting of curved paths G1 and G3 is S-shaped as a whole, but this is only an example, and the number of rollers and the shape of the transport path are variously deformed. It is possible.
Further, although a configuration example is shown in which the corner bending straightening portions 51a, 51b, 71a, 71b composed of tapered edge portions extend linearly, the edge portions extending inwardly and convexly curved outwards. It may be an edge portion that extends.

第二実施形態に係る紙幣（紙葉）の角折れ矯正装置によれば、紙幣をＳ字状に湾曲した搬送経路に沿って搬送するので、一回の往復搬送により、紙幣の両端に位置する表裏両面の角折れ片をローラ周面から離間する方向へ起こすことが可能である。つまり、紙幣の一面がローラの外周面（湾曲案内凸面）と接触しつつ外周面に沿って湾曲した状態に変形させられることにより、紙幣の他面側に形成された角折れ片は起立方向、即ちローラ外周面から離間する方向へ起き上がり易くなる。この作用によって、起立方向に変形した角折れ片をテーパー状のエッジ部から成る角折れ矯正部５１ａ、５１ｂ、７１ａ、７１ｂが確実に引っ掛けることが可能となり、角折れ片を平坦に修正できる。
本実施形態に係る角折れ矯正装置１は、部品点数が少なく、構成がシンプルであるため、小型化、簡易構造化、低コスト化が可能でありながら、表裏両面の全ての角折れ片を矯正することができる。 According to the corner fold correction device for banknotes (paper sheets) according to the second embodiment, the banknotes are transported along an S-shaped curved transport path, and are therefore located at both ends of the banknotes by one round-trip transport. It is possible to raise the corner folds on both the front and back sides in a direction away from the peripheral surface of the roller. That is, one side of the bill is deformed into a curved state along the outer peripheral surface while being in contact with the outer peripheral surface (curved guide convex surface) of the roller, so that the corner-folded piece formed on the other side of the bill is in the upright direction. That is, it is easy to get up in the direction away from the outer peripheral surface of the roller. By this action, the corner fold straightening portions 51a, 51b, 71a, 71b formed of the tapered edge portion can surely hook the corner fold piece deformed in the upright direction, and the corner fold piece can be corrected flat.
The corner fold straightening device 1 according to the present embodiment has a small number of parts and a simple structure, so that it is possible to reduce the size, simple structure, and cost, and correct all the corner folds on both the front and back sides. can do.

＜第三実施形態＞
図８は本発明の第三実施形態に係る紙幣（紙葉）の角折れ矯正装置の構成を示す外観斜視図、図９はその正面図である。
なお、第三実施形態と第一、第二実施形態との主たる相違点は、ローラ（第一湾曲搬送ガイド部材）の個数と、外側ガイド部材の形状である。従って、同一機能を有した部位には同一符号を付して説明する。
この実施形態に係る紙幣の角折れ矯正装置１では、第一湾曲搬送ガイド部材が、一個の円筒状（又は円柱状）の回転自在なローラであり、ローラを正逆回転駆動することにより紙幣を往復搬送するようにしている。 <Third Embodiment>
FIG. 8 is an external perspective view showing the configuration of a corner fold correction device for a banknote (paper leaf) according to a third embodiment of the present invention, and FIG. 9 is a front view thereof.
The main differences between the third embodiment and the first and second embodiments are the number of rollers (first curved transport guide member) and the shape of the outer guide member. Therefore, the parts having the same function will be described with the same reference numerals.
In the banknote corner bending straightening device 1 according to this embodiment, the first curved transport guide member is a single cylindrical (or columnar) rotatable roller, and the banknote is driven by forward and reverse rotation driving of the roller. I try to carry it back and forth.

角折れ矯正装置１は、紙幣搬送方向と直交する方向へ延びる回転軸１０ａを中心として正逆回転して紙幣の一面に接する一個の円筒状のローラ（第一湾曲搬送ガイド部材、搬送手段）１０と、ローラ１０の外周面（湾曲案内凸面）との間に紙幣の通過を許容するガイド用の湾曲路Ｇ１を形成しつつ該紙幣の他面をガイドする湾曲案内凹面を備えた外側ガイド部材５０と、外側ガイド部材５０の搬送方向両端縁に夫々設けられた角折れ矯正部（エッジ部）５１ａ、５１ｂと、ローラ１０を矢印Ａで示す正方向と矢印Ｂで示す逆方向へ正逆切替え駆動して湾曲路Ｇ１内で紙幣を往復搬送するための駆動手段と、駆動手段を制御する制御手段と、を備えた構成が特徴的である。
補助ローラ１２は外側ガイド部材５０の適所（本例では幅方向中央部）に形成した開口を介して湾曲路内の紙幣の外側面と接しつつ回転することにより紙幣の搬送をサポートする手段である。 The corner fold correction device 1 is a single cylindrical roller (first curved transport guide member, transport means) 10 that rotates forward and reverse around a rotation shaft 10a extending in a direction orthogonal to the bill transport direction and is in contact with one surface of the bill. An outer guide member 50 having a curved guide concave surface that guides the other surface of the banknote while forming a curved path G1 for a guide that allows the passage of the banknote between the roller 10 and the outer peripheral surface (curved guide convex surface). And the corner bending straightening portions (edge portions) 51a and 51b provided at both ends of the outer guide member 50 in the transport direction, and the roller 10 is driven to switch forward and reverse in the forward direction indicated by the arrow A and the reverse direction indicated by the arrow B. A characteristic feature is a configuration including a driving means for reciprocating and transporting banknotes in the curved road G1 and a control means for controlling the driving means.
The auxiliary roller 12 is a means for supporting the transport of banknotes by rotating while being in contact with the outer surface of the banknotes in the curved path through an opening formed at an appropriate position (central portion in the width direction in this example) of the outer guide member 50. ..

角折れ矯正部５１ａ、５１ｂは、湾曲路Ｇ１の搬送方向両端部に相当する外側ガイド部材５０の両端縁に夫々設けられている。各角折れ矯正部５１ａ、５１ｂは、遊端側へ向かう程、平面視の幅がテーパー状（ハ字状）に漸減する。
紙幣が各湾曲路Ｇ１の外側、即ち方向Ａから湾曲路Ｇ１内に進入する際に紙幣の搬送方向後端、且つ表側に位置する角折れ片が傾斜して延びる角折れ矯正部５１ａに引っ掛かって徐々に引き起こされ、その後ローラ外周面（湾曲案内凸面）と外側ガイド部材の湾曲案内凹面との間で加圧されつつ姿勢矯正されて平坦化される。このように紙幣を一方向に搬送して湾曲路Ｇ１内に進入させ、後端部が角折れ矯正部５１ａを通過することにより紙幣後端部の角折れ片の矯正が行われる。 The corner bending straightening portions 51a and 51b are provided on both end edges of the outer guide member 50 corresponding to both ends in the transport direction of the curved path G1, respectively. The width of each of the corner fold correction portions 51a and 51b gradually decreases in a tapered shape (H-shape) toward the free end side.
When a bill enters the outside of each curved path G1, that is, from the direction A into the curved path G1, the corner folds located at the rear end in the transport direction of the bill and on the front side are caught by the corner fold correction portion 51a extending in an inclined manner. It is gradually raised, and then the posture is corrected and flattened while being pressurized between the outer peripheral surface of the roller (convex curved guide surface) and the concave curved guide surface of the outer guide member. In this way, the banknote is conveyed in one direction and entered into the curved path G1, and the rear end portion passes through the corner fold correction portion 51a to correct the corner fold piece at the rear end portion of the bill.

紙幣の先端、且つ表側にある角折れ片は、紙幣が各湾曲路Ｇ１内を方向Ａに移動して、一旦角折れ矯正部５１ｂを通過してから逆方向に戻り搬送される際に各角折れ矯正部５１ｂによって姿勢矯正される。
紙幣の裏側へ折れた角折れ片１０２、１０４を矯正するためには、紙幣１００の裏面側が凸、表面側が凹となるように湾曲させた状態にて角折れ片１０２、１０４が角折れ矯正部５１ａ、５１ｂを通過するようにすればよい。即ち、湾曲路Ｇ１内で往復搬送した紙幣１００をＡ方向に搬送して湾曲路Ｇ１外へ完全に離脱させた後、矢印Ｃに示すようにスイッチバックで後端（角折れ片１０４のある端縁）からＡ方向に湾曲路Ｇ１へ再導入することにより、最初の往復搬送時とは紙幣の表裏を逆転させた状態で湾曲路Ｇ１内を往復搬送すればよい。
なお、第二実施形態のように本実施形態に係る角折れ矯正装置１を２個以上並列に配置して全体としてＳ字状の搬送経路を形成してもよい。 The corner folds at the tip of the bill and on the front side are each corner when the bill moves in each curved path G1 in the direction A, once passes through the corner fold correction portion 51b, and then returns in the opposite direction and is conveyed. The posture is corrected by the fold correction portion 51b.
In order to correct the corner fold pieces 102 and 104 that are folded toward the back side of the bill, the corner fold pieces 102 and 104 are bent so that the back side of the bill 100 is convex and the front side is concave. It may pass through 51a and 51b. That is, after the banknote 100 reciprocated in the curved road G1 is transported in the A direction and completely separated from the curved road G1, the rear end (the end with the corner-folded piece 104) is switched back as shown by the arrow C. By reintroducing the banknotes from the edge) into the curved path G1 in the A direction, the banknotes may be reciprocated in the curved path G1 with the front and back sides reversed from those at the time of the first reciprocating transfer.
As in the second embodiment, two or more corner break correction devices 1 according to the present embodiment may be arranged in parallel to form an S-shaped transport path as a whole.

第三実施形態に係る紙幣（紙葉）の角折れ矯正装置によれば、紙幣をＣ字状に湾曲した搬送経路に沿って搬送するので、搬送経路内で往復搬送した後、紙幣の表裏を逆転させて搬送経路内で往復搬送することにより、紙幣の両端に位置する表裏両面の角折れ片をローラ周面から離間する方向へ起こすことが可能である。つまり、紙幣の一面がローラの外周面（湾曲案内凸面）と接触しつつ外周面に沿って湾曲した状態に変形させられることにより、紙幣の他面側に形成された角折れ片は起立方向、即ちローラ外周面から離間する方向へ起き上がり易くなる。この作用によって、起立方向に変形した角折れ片をテーパー状のエッジ部から成る角折れ矯正部５１ａ、５１ｂが確実に引っ掛けることが可能となり、角折れ片を平坦に修正できる。
本例においては、外側ガイド部材５０の幅方向両端の２つのエッジ部（角折れ矯正部５１ａ）が凸状に湾曲して延びる構成例を示したが、直線状に延びるエッジ部、或いは内側へ凹状に湾曲して延びるエッジ部としてもよい。
本実施形態に係る角折れ矯正装置１は、部品点数が少なく、構成がシンプルであるため、小型化、簡易構造化、低コスト化が可能でありながら、表裏両面の全ての角折れ片を矯正することができる。 According to the corner fold correction device for banknotes (paper sheets) according to the third embodiment, the banknotes are transported along a transport path curved in a C shape. By reversing and reciprocating in the transport path, it is possible to raise the corner-folded pieces on both the front and back sides of the bill in a direction away from the peripheral surface of the roller. That is, one side of the bill is deformed into a curved state along the outer peripheral surface while being in contact with the outer peripheral surface (curved guide convex surface) of the roller, so that the corner-folded piece formed on the other side of the bill is in the upright direction.

That is, the width of the corner fold correction portions 11c and 11d gradually increases in a tapered shape (H-shape) toward the free end side.

紙幣１００が湾曲路Ｇ１の外側、即ち方向Ａから湾曲路Ｇ１内に進入する際に紙幣の搬送方向後端、且つ表側に位置する角折れ片１０３が傾斜して延びる角折れ矯正部５１ａに引っ掛かって徐々に引き起こされ、その後内側ガイド部材１５の外周面（湾曲案内凸面）と外側ガイド部材の湾曲案内凹面との間で加圧されつつ姿勢矯正されて平坦化される。このように紙幣を一方向に搬送して湾曲路Ｇ１内に進入させ、後端部が角折れ矯正部５１ａを通過することにより角折れ片１０３の矯正が行われる。
紙幣の搬送方向先端、且つ表側にある角折れ片１０１は、紙幣１００の先端部が湾曲路Ｇ１内を方向Ａに移動して、一旦角折れ矯正部５１ｂを通過してから逆方向に戻り搬送される際に各角折れ矯正部５１ｂによって姿勢矯正される。
紙幣の搬送方向後端、且つ裏側にある角折れ片１０４は、紙幣１００が方向Ａから湾曲路Ｇ１内に進入する際に、角折れ矯正部１１ａによって姿勢矯正される。角折れ矯正部１１ａによって充分に姿勢矯正されなかった場合、この角折れ片１０４は、更に湾曲路Ｇ１内をＡ方向に搬送される過程で角折れ矯正部１１ｄによって再度姿勢矯正される。 When the bill 100 enters the curved road G1 from the outside of the curved road G1, that is, from the direction A, the corner fold piece 103 located at the rear end in the transport direction of the bill and on the front side is caught by the corner fold straightening portion 51a extending in an inclined manner. Then, the posture is corrected and flattened while being pressurized between the outer peripheral surface (curved guide convex surface) of the inner guide member 15 and the curved guide concave surface of the outer guide member. In this way, the banknotes are conveyed in one direction to enter the curved road G1, and the rear end portion passes through the corner fold correction portion 51a to correct the corner fold piece 103.
At the tip of the banknote in the transport direction and on the front side, the tip of the banknote 100 moves in the curved path G1 in the direction A, passes through the corner fold correction section 51b, and then returns in the opposite direction for transport. At that time, the posture is corrected by each corner bending correction portion 51b.
When the bill 100 enters the curved path G1 from the direction A, the corner fold straightening portion 11a corrects the posture of the corner fold piece 104 at the rear end in the transport direction of the bill and on the back side. If the posture is not sufficiently corrected by the corner bending correction portion 11a, the corner bending piece 104 is further corrected in posture by the corner bending correction portion 11d in the process of being conveyed in the A direction in the curved road G1.

紙幣の搬送方向先端、且つ裏側にある角折れ片１０２は、紙幣１００の先端部が湾曲路Ｇ１内を方向Ａに移動して、一旦角折れ矯正部１１ｂを通過してから逆方向に戻り搬送される際に各角折れ矯正部１１ｂによって姿勢矯正される。角折れ矯正部１１ｂによって充分に姿勢矯正されなかった場合、この角折れ片１０２は、更に湾曲路Ｇ１内をＢ方向に搬送される過程で角折れ矯正部１１ｃによって再度姿勢矯正される。
角折れ矯正部１１ｃ、１１ｄの搬送方向長と幅方向長（幅方向端縁からの切り込みの深さと角度θ２は、角折れ矯正部１１ａ、１１ｂの角度θ１と同一としてもよい。しかし、角折れ片に対して最適な引き起こし効果を与える角折れ矯正部の形状は、角折れ片の形状によって異なる。従って、角折れ矯正部１１ｃ、１１ｄを、角折れ矯正部１１ａ、１１ｂとは異なる搬送方向長と幅方向長に設定することで、角折れ片に対して２つの角折れ矯正部間で異なる矯正力を作用させることが可能となり、角折れ矯正部１１ｃ、１１ｄによる補助的な角折れ矯正が効果的に行われる。 The corner-folded piece 102 at the tip of the bill in the transport direction and on the back side has the tip of the bill 100 moving in the curved path G1 in the direction A, once passing through the corner-folding straightening portion 11b, and then returning in the opposite direction for transport. At that time, the posture is corrected by each corner bending correction portion 11b. If the posture is not sufficiently corrected by the corner bending correction portion 11b, the corner bending piece 102 is further corrected in posture by the corner bending correction portion 11c in the process of being conveyed in the B direction in the curved road G1.
Conveyance direction length and width direction length of the corner fold straightening portions 11c and 11d (the depth of cut from the width direction edge and the angle θ2 may be the same as the angle θ1 of the corner fold straightening portions 11a and 11b. The shape of the corner fold straightening portion that gives the optimum raising effect to the piece differs depending on the shape of the corner fold piece. Therefore, the corner fold straightening portions 11c and 11d have different transport direction lengths from the corner fold straightening portions 11a and 11b. By setting the length in the width direction to, it is possible to apply different correction forces between the two corner fold correction parts to the corner fold piece, and auxiliary corner fold correction by the corner fold correction parts 11c and 11d can be performed. It is done effectively.

第四実施形態に係る紙幣（紙葉）の角折れ矯正装置によれば、紙幣の面に接触する外側ガイド部材と紙幣の裏面に接触する内側ガイド部材の双方に、テーパー状のエッジ部から成る角折れ矯正部５１ａ、５１ｂ、１１ａ〜１１ｄを備えたので、紙幣をＣ字状に湾曲した搬送経路に沿って１回の往復搬送を実施することにより、紙幣の搬送方向両端に位置する表裏両面の角折れ片を矯正することが可能である。
つまり、紙幣の一面（裏面）が内側ガイド部材１５の外周面（湾曲案内凸面）と接触しつつ外周面に沿って湾曲した状態に変形させられることにより、紙幣の他面側（裏面側）に形成された角折れ片は起立方向、即ち内側ガイド部材の外周面から離間する方向へ起き上がり易くなる。この作用によって、起立方向に変形した角折れ片をテーパー状のエッジ部から成る角折れ矯正部５１ａ、５１ｂが確実に引っ掛けることが可能となり、角折れ片を平坦に修正できる。 According to the corner fold correction device for banknotes (paper sheets) according to the fourth embodiment, both the outer guide member that contacts the front surface of the banknote and the inner guide member that contacts the back surface of the banknote are composed of tapered edges. Since the corner fold straightening portions 51a, 51b, 11a to 11d are provided, both front and back sides of the banknotes are located at both ends in the banknote transport direction by carrying out one reciprocating transport of the bills along a transport path curved in a C shape. It is possible to correct broken corners.
That is, one surface (back surface) of the banknote is deformed into a curved state along the outer peripheral surface while being in contact with the outer peripheral surface (curved guide convex surface) of the inner guide member 15, so that the other surface side (back surface side) of the banknote is formed. The formed corner folds tend to rise in the upright direction, that is, in the direction away from the outer peripheral surface of the inner guide member. By this action, the corner fold straightening portions 51a and 51b formed of the tapered edge portion can surely hook the corner fold piece deformed in the upright direction, and the corner fold piece can be corrected flat.

また、内側ガイド部材１５は中空状となっており、紙幣の一面側（裏面側）に位置する未矯正の角折れ片は、内側ガイド部材１５の中空部側に折れ曲がった（突出した）姿勢で角折れ矯正部を通過する。従って、この角折れ片は搬送される過程で傾斜して延びる角折れ矯正部１１ａ〜１１ｄに引っ掛かって徐々に引き起こされ、その後、内側ガイド部材の外周面（湾曲案内凸面）と外側ガイド部材の内周面（湾曲案内凹面）との間で加圧されつつ姿勢矯正されて平坦化される。
本実施形態に係る角折れ矯正装置１は、部品点数が少なく、構成がシンプルであるため、小型化、簡易構造化、低コスト化が可能でありながら、表裏両面の全ての角折れ片を矯正することができる。内側ガイド部材１５の内側に形成される中空状の空間を有効活用することにより、更に装置の小型化を図ることができる。 Further, the inner guide member 15 has a hollow shape, and the uncorrected corner folds located on one side (back side) of the bill are in a bent (protruding) posture toward the hollow portion side of the inner guide member 15. Pass through the corner break correction part. Therefore, the corner fold pieces are gradually caused by being caught by the corner fold straightening portions 11a to 11d extending in an inclined manner in the process of being conveyed, and then the outer peripheral surface (curved guide convex surface) of the inner guide member and the inner side of the outer guide member. The posture is corrected and flattened while being pressurized with the peripheral surface (curved guide concave surface).
The corner fold straightening device 1 according to the present embodiment has a small number of parts and a simple structure, so that it is possible to reduce the size, simple structure, and cost, and correct all the corner folds on both the front and back sides. can do. By effectively utilizing the hollow space formed inside the inner guide member 15, the device can be further miniaturized.

なお、紙幣の裏側へ折れた角折れ片１０２、１０４を、より確実に矯正するためには、紙幣の裏面側が突出するように湾曲させた状態にて角折れ片が角折れ矯正部を通過するようにすればよい。即ち、第二実施形態のように本実施形態に係る角折れ矯正装置１を２個以上並列に配置して全体としてＳ字状の搬送経路を形成するか、反転させた紙幣を後端からＡ方向に湾曲路Ｇ１へと再導入することにより、紙幣の表裏を逆転させた状態で湾曲路Ｇ１内を往復搬送すればよい。 In order to more reliably correct the corner-folded pieces 102 and 104 that are folded toward the back side of the bill, the corner-folded pieces pass through the corner-folded straightening portion in a state of being curved so that the back side of the bill protrudes. You can do it like this. That is, as in the second embodiment, two or more corner break correction devices 1 according to the present embodiment are arranged in parallel to form an S-shaped transport path as a whole, or the inverted banknotes are A from the rear end. By reintroducing the banknotes into the curved road G1 in the direction, the bills may be reciprocated in the curved road G1 with the front and back sides reversed.

図１２は本発明の第五実施形態に係る紙幣（紙葉）の角折れ矯正装置の構成を示す外観斜視図、図１３はその正面図である。
なお、第五実施形態と第一乃至第四実施形態との主たる相違点は、傾斜して延びる角折れ矯正部の代わりにブラシ状の角折れ矯正部を配置した点にある。以下、同一機能を有した部位には同一符号を付して説明する。
この実施形態に係る紙幣の角折れ矯正装置１では、第一湾曲搬送ガイド部材が、一個の円筒状（又は円柱状）の回転自在なローラであり、ローラを正逆回転駆動することにより紙幣を往復搬送するようにしている。 <Fifth Embodiment>
FIG. 12 is an external perspective view showing the configuration of a corner fold correction device for a banknote (paper leaf) according to a fifth embodiment of the present invention, and FIG. 13 is a front view thereof.
The main difference between the fifth embodiment and the first to fourth embodiments is that a brush-shaped corner fold correction portion is arranged instead of the inclined corner fold correction portion. Hereinafter, the parts having the same function will be described with the same reference numerals.
In the banknote corner bending straightening device 1 according to this embodiment, the first curved transport guide member is a single cylindrical (or columnar) rotatable roller, and the banknote is driven by forward and reverse rotation driving of the roller. I try to carry it back and forth.

角折れ矯正装置１は、紙幣搬送方向と直交する方向へ延びる回転軸１０ａを中心として正逆回転して紙幣の一面に接する一個の円筒状のローラ（第一湾曲搬送ガイド部材、搬送手段）１０と、ローラ１０の外周面（湾曲案内凸面）との間に紙幣の通過を許容するガイド用の湾曲路Ｇ１を形成しつつ該紙幣の他面をガイドする湾曲案内凹面を備えた外側ガイド部材５０と、外側ガイド部材５０の搬送方向各端部に設けられたブラシ（角折れ矯正部）５４、５５と、ローラ１０を矢印Ａで示す正方向（導入方向）と矢印Ｂで示す逆方向へ正逆切替え駆動して湾曲路Ｇ１内で紙幣を往復搬送するための駆動手段と、駆動手段を制御する制御手段と、を備えた構成が特徴的である。
補助ローラ１２はブラシ５４、５４の間、及びブラシ５５、５５の間（幅方向中間部）に夫々配置され、湾曲路Ｇ１外に露出した紙幣の外側面と接しつつ回転することにより、紙幣の搬送をサポートする。 The corner fold correction device 1 is a single cylindrical roller (first curved transport guide member, transport means) 10 that rotates forward and reverse around a rotation shaft 10a extending in a direction orthogonal to the bill transport direction and is in contact with one surface of the bill. An outer guide member 50 having a curved guide concave surface that guides the other surface of the bill while forming a guide curved path G1 that allows the passage of the bill between the roller 10 and the outer peripheral surface (curved guide convex surface). The brushes (corner fold correction portions) 54 and 55 provided at each end of the outer guide member 50 in the transport direction and the roller 10 are positive in the forward direction (introduction direction) indicated by the arrow A and in the opposite direction indicated by the arrow B. It is characterized by a configuration including a driving means for reverse switching driving and reciprocating and transporting banknotes in the curved road G1 and a control means for controlling the driving means.
The auxiliary rollers 12 are arranged between the brushes 54 and 54 and between the brushes 55 and 55 (intermediate portion in the width direction), and rotate while being in contact with the outer surface of the banknote exposed outside the curved path G1 to obtain the banknote. Supports transportation.

外側ガイド部材５０は、ローラ１０との間で湾曲路Ｇ１を形成する本体５０ａと、本体５０ａの搬送方向各端部に配置されたブラシ５４、５５とを備える。ブラシ５４、５５は、搬送路の幅方向両端部に配置されている。ブラシ５４、５５は、ローラ１０の外周面（湾曲路形成面）に向けて突出する複数の突起（線材、或いは毛束）５４ａ、５５ａを有しており、各線材の先端が搬送される紙幣の他面（表面）に位置する角折れ片に接触することによって、各角折れ片を引き起こす効果を発揮する。ブラシ５４、５４とブラシ５５、５５とは、外側ガイド部材５０の遊端側の間隔が狭くなるように（ハ字状に）配置してもよい。 The outer guide member 50 includes a main body 50a that forms a curved path G1 with the roller 10, and brushes 54 and 55 arranged at each end of the main body 50a in the transport direction. The brushes 54 and 55 are arranged at both ends in the width direction of the transport path. The brushes 54 and 55 have a plurality of protrusions (wire rods or hair bundles) 54a and 55a protruding toward the outer peripheral surface (curved path forming surface) of the roller 10, and the tip of each wire rod is conveyed. By contacting the corner folds located on the other surface (surface), the effect of causing each corner fold is exhibited. The brushes 54 and 54 and the brushes 55 and 55 may be arranged (in a C shape) so that the distance between the brushes 54 and 54 and the brushes 55 and 55 on the free end side of the outer guide member 50 is narrowed.

紙幣が湾曲路Ｇ１の外側、方向Ａから湾曲路Ｇ１内に進入する際に、紙幣の搬送方向後端、且つ表側に位置する角折れ片がブラシ５４の突起５４ａに接触して引き起こされた状態で湾曲路Ｇ１内に導入される。引き起こされた角折れ片は、ローラ１０の外周面（湾曲案内凸面）と外側ガイド部材５０の本体５０ａの湾曲案内凹面との間で加圧されつつ姿勢矯正されて平坦化される。このように紙幣を一方向に搬送して湾曲路Ｇ１内に進入させ、後端部がブラシ５４部分を通過することにより紙幣後端部の角折れ片の矯正が行われる。
紙幣の先端、且つ表側にある角折れ片は、紙幣が各湾曲路Ｇ１内を方向Ａに移動して、一旦ブラシ５５部分を通過してから逆方向に戻り搬送される際に各ブラシ５５によって姿勢矯正される。
紙幣の裏側へ折れた角折れ片１０２、１０４を矯正するためには、第三の実施形態（図９）に示したように、紙幣１００の裏面側が凸、表面側が凹となるように湾曲させた状態にて角折れ片１０２、１０４が各ブラシ５４、５５を通過するようにすればよい。即ち、湾曲路Ｇ１内で往復搬送した紙幣１００をＡ方向に搬送して湾曲路Ｇ１外へ完全に離脱させた後、矢印Ｃに示すようにスイッチバックで後端（角折れ片１０４のある端縁）からＡ方向に湾曲路Ｇ１へ再導入することにより、最初の往復搬送時とは紙幣の表裏を逆転させた状態で湾曲路Ｇ１内を往復搬送すればよい。
なお、第二実施形態のように本実施形態に係る角折れ矯正装置１を２個以上並列に配置して全体としてＳ字状の搬送経路を形成してもよい。 A state in which when a bill enters the curved road G1 from the outside of the curved road G1 and from the direction A, a corner fold piece located at the rear end in the transport direction of the bill and on the front side comes into contact with the protrusion 54a of the brush 54. Is introduced into the curved road G1. The raised corner folds are posture-corrected and flattened while being pressurized between the outer peripheral surface (curved guide convex surface) of the roller 10 and the curved guide concave surface of the main body 50a of the outer guide member 50. In this way, the banknote is conveyed in one direction and entered into the curved path G1, and the rear end portion passes through the brush 54 portion to correct the corner broken piece at the rear end portion of the banknote.
The corner folds on the tip and front side of the bill are moved by each brush 55 when the bill moves in each curved path G1 in the direction A, passes through the brush 55 portion once, and then returns in the opposite direction and is conveyed. Posture is corrected.
In order to correct the corner-folded pieces 102 and 104 that are folded toward the back side of the banknote, as shown in the third embodiment (FIG. 9), the banknote 100 is curved so that the back surface side is convex and the front surface side is concave. In this state, the corner-folded pieces 102 and 104 may pass through the brushes 54 and 55, respectively. That is, after the banknote 100 reciprocated in the curved road G1 is transported in the A direction and completely separated from the curved road G1, the rear end (the end with the corner-folded piece 104) is switched back as shown by the arrow C. By reintroducing the banknotes from the edge) into the curved path G1 in the A direction, the banknotes may be reciprocated in the curved path G1 with the front and back sides reversed from those at the time of the first reciprocating transfer.
As in the second embodiment, two or more corner break correction devices 1 according to the present embodiment may be arranged in parallel to form an S-shaped transport path as a whole.

第五実施形態に係る紙幣（紙葉）の角折れ矯正装置によれば、紙幣をＣ字状に湾曲した搬送経路に沿って搬送するので、搬送経路内で往復搬送した後、紙幣の表裏を逆転させて搬送経路内で往復搬送することにより、紙幣の両端に位置する表裏両面の角折れ片をローラ周面から離間する方向へ起こすことが可能である。つまり、紙幣の一面がローラの外周面（湾曲案内凸面）と接触しつつ外周面に沿って湾曲した状態に変形させられることにより、紙幣の他面側に形成された角折れ片は起立方向、即ちローラ外周面から離間する方向へ起き上がり易くなる。この作用によって、起立方向に変形した角折れ片をブラシ５４、５５の複数の突起５４ａ、５５ａが確実に引っ掛けることが可能となり、角折れ片を平坦に修正できる。
本実施形態に係る角折れ矯正装置１は、部品点数が少なく、構成がシンプルであるため、小型化、簡易構造化、低コスト化が可能でありながら、表裏両面の全ての角折れ片を矯正することができる。 According to the corner fold correction device for banknotes (paper sheets) according to the fifth embodiment, the banknotes are transported along a transport path curved in a C shape.

＜第六実施形態＞
図１４は本発明の第六実施形態に係る紙幣（紙葉）の角折れ矯正装置の構成を示す外観斜視図、図１５はその正面図である。
なお、第六実施形態と第五実施形態との主たる相違点は、傾斜して延びる角折れ矯正部の代わりに、スクレーパ状の角折れ矯正部を配置した点にある。以下、同一機能を有した部位には同一符号を付して説明する。
この実施形態に係る紙幣の角折れ矯正装置１では、第一湾曲搬送ガイド部材が、一個の円筒状（又は円柱状）の回転自在なローラであり、ローラを正逆回転駆動することにより紙幣を往復搬送するようにしている。 <Sixth Embodiment>
FIG. 14 is an external perspective view showing the configuration of a corner fold correction device for a banknote (paper leaf) according to a sixth embodiment of the present invention, and FIG. 15 is a front view thereof.
The main difference between the sixth embodiment and the fifth embodiment is that a scraper-shaped corner fold correction portion is arranged instead of the inclined corner fold correction portion. Hereinafter, the parts having the same function will be described with the same reference numerals.
In the banknote corner bending straightening device 1 according to this embodiment, the first curved transport guide member is a single cylindrical (or columnar) rotatable roller, and the banknote is driven by forward and reverse rotation driving of the roller. I try to carry it back and forth.

角折れ矯正装置１は、紙幣搬送方向と直交する方向へ延びる回転軸１０ａを中心として正逆回転して紙幣の一面に接する一個の円筒状のローラ（第一湾曲搬送ガイド部材、搬送手段）１０と、ローラ１０の外周面（湾曲案内凸面）との間に紙幣の通過を許容するガイド用の湾曲路Ｇ１を形成しつつ該紙幣の他面をガイドする湾曲案内凹面を備えた外側ガイド部材５０と、外側ガイド部材５０の搬送方向各端部に設けられてローラ１０の外周面（湾曲路形成面）に向けて突出したスクレーパ（突出片、角折れ矯正部）５６、５７と、ローラ１０を矢印Ａで示す正方向と矢印Ｂで示す逆方向へ正逆切替え駆動して湾曲路Ｇ１内で紙幣を往復搬送するための駆動手段と、駆動手段を制御する制御手段と、を備えた構成が特徴的である。 The corner fold correction device 1 is a single cylindrical roller (first curved transport guide member, transport means) 10 that rotates forward and reverse around a rotation shaft 10a extending in a direction orthogonal to the bill transport direction and is in contact with one surface of the bill. An outer guide member 50 having a curved guide concave surface that guides the other surface of the banknote while forming a curved path G1 for a guide that allows the passage of the banknote between the roller 10 and the outer peripheral surface (curved guide convex surface). Scrapers (protruding pieces, corner break correction portions) 56, 57 provided at each end of the outer guide member 50 in the transport direction and projecting toward the outer peripheral surface (curved path forming surface) of the roller 10, and the roller 10 A configuration including a driving means for reciprocating and transporting banknotes in the curved path G1 by driving forward / reverse switching in the forward direction indicated by the arrow A and the reverse direction indicated by the arrow B, and a control means for controlling the driving means. It is characteristic.

補助ローラ１２はスクレーパ５６、５６の間、及びスクレーパ５７、５７の間（幅方向中間部）に夫々配置され、湾曲路Ｇ１外に露出した紙幣の外側面と接しつつ回転することにより、紙幣の搬送をサポートする。 The auxiliary rollers 12 are arranged between the scrapers 56 and 56 and between the scrapers 57 and 57 (intermediate portion in the width direction), and rotate while being in contact with the outer surface of the banknote exposed outside the curved path G1 to obtain the banknote. Supports transportation.

外側ガイド部材５０は、ローラ１０との間で湾曲路Ｇ１を形成する本体５０ａと、本体５０ａの搬送方向各端部によって支持されたスクレーパ５６、５７とを備える。本例では、スクレーパ５６、５７の先端部５６ａ、５７ａが搬送される紙幣の他面（表面）に位置する角折れ片に接触することによって、各角折れ片を引き起こす効果を発揮する。スクレーパ５６、５６とスクレーパ５７、５７とは、外側ガイド部材５０の遊端側の間隔が狭くなるように（ハ字状に）配置してもよい。 The outer guide member 50 includes a main body 50a that forms a curved path G1 with the roller 10, and scrapers 56 and 57 supported by ends of the main body 50a in the transport direction. In this example, the tips 56a and 57a of the scrapers 56 and 57 come into contact with the corner folds located on the other surface (front surface) of the bill to be conveyed, thereby exerting the effect of causing each corner fold. The scrapers 56, 56 and the scrapers 57, 57 may be arranged (in a C shape) so that the distance between the scrapers 56, 56 and the scrapers 57, 57 on the free end side of the outer guide member 50 is narrowed.

紙幣が湾曲路Ｇ１の外側、方向Ａから湾曲路Ｇ１内に進入する際に、紙幣の搬送方向後端、且つ表側に位置する角折れ片がスクレーパ５６の先端部５６ａに接触して引き起こされた状態で湾曲路Ｇ１内に導入される。引き起こされた角折れ片は、ローラ１０の外周面（湾曲案内凸面）と外側ガイド部材５０の本体５０ａの湾曲案内凹面との間で加圧されつつ姿勢矯正されて平坦化される。このように紙幣を一方向に搬送して湾曲路Ｇ１内に進入させ、後端部がスクレーパ５６部分を通過することにより紙幣後端部の角折れ片の矯正が行われる。
紙幣の先端、且つ表側にある角折れ片は、紙幣が各湾曲路Ｇ１内を方向Ａに移動して、一旦スクレーパ５７部分を通過してから逆方向に戻り搬送される際に各スクレーパ５７によって姿勢矯正される。
紙幣の裏側へ折れた角折れ片を矯正するためには、紙幣の裏面側が突出するように湾曲させた状態にて角折れ片が角折れ矯正部を通過するようにすればよい。即ち、湾曲路Ｇ１内で往復搬送した紙幣をＡ方向に搬送して湾曲路Ｇ１外へ完全に離脱させた後、スイッチバックで紙幣を後端からＡ方向に湾曲路Ｇ１へと導入することにより、紙幣の表裏を逆転させた状態で再度湾曲路Ｇ１内を往復搬送すればよい。
なお、第二実施形態のように本実施形態に係る角折れ矯正装置１を２個以上並列に配置して全体としてＳ字状の搬送経路を形成してもよい。 When a bill enters the curved road G1 from the outside of the curved road G1 from the direction A, a corner fold piece located at the rear end in the transport direction of the bill and on the front side comes into contact with the tip portion 56a of the scraper 56 and is caused. In the state, it is introduced into the curved road G1. The raised corner folds are posture-corrected and flattened while being pressurized between the outer peripheral surface (curved guide convex surface) of the roller 10 and the curved guide concave surface of the main body 50a of the outer guide member 50. In this way, the banknote is conveyed in one direction and entered into the curved path G1, and the rear end portion passes through the scraper 56 portion, so that the corner broken piece at the rear end portion of the banknote is corrected.
The corner folds on the tip and front side of the bill are moved by each scraper 57 when the bill moves in each curved path G1 in the direction A, passes through the scraper 57 portion, and then returns in the opposite direction and is conveyed. Posture is corrected.
In order to correct the corner folds that are folded toward the back side of the bill, the corner folds may pass through the corner fold correction portion in a state of being curved so that the back side of the bill protrudes. That is, after the banknotes reciprocally transported in the curved path G1 are conveyed in the A direction and completely separated from the curved path G1, the banknotes are introduced into the curved path G1 from the rear end in the A direction by switchback. , The bill may be reciprocated in the curved road G1 again with the front and back sides reversed.
As in the second embodiment, two or more corner break correction devices 1 according to the present embodiment may be arranged in parallel to form an S-shaped transport path as a whole.

第六実施形態に係る紙幣（紙葉）の角折れ矯正装置によれば、紙幣をＣ字状に湾曲した搬送経路に沿って搬送するので、搬送経路内で往復搬送した後、紙幣の表裏を逆転させて搬送経路内で往復搬送することにより、紙幣の両端に位置する表裏両面の角折れ片をローラ周面から離間する方向へ起こすことが可能である。つまり、紙幣の一面がローラの外周面（湾曲案内凸面）と接触しつつ外周面に沿って湾曲した状態に変形させられることにより、紙幣の他面側に形成された角折れ片は起立方向、即ちローラ外周面から離間する方向へ起き上がり易くなる。この作用によって、起立方向に変形した角折れ片をスクレーパ５６、５７の先端部５６ａ、５７ａが確実に引っ掛けることが可能となり、角折れ片を平坦に修正できる。
本実施形態に係る角折れ矯正装置１は、部品点数が少なく、構成がシンプルであるため、小型化、簡易構造化、低コスト化が可能でありながら、表裏両面の全ての角折れ片を矯正することができる。 According to the corner fold correction device for banknotes (paper sheets) according to the sixth embodiment, the banknotes are transported along a transport path curved in a C shape. By reversing and reciprocating in the transport path, it is possible to raise the corner-folded pieces on both the front and back sides of the bill in a direction away from the peripheral surface of the roller. That is, one side of the bill is deformed into a curved state along the outer peripheral surface while being in contact with the outer peripheral surface (curved guide convex surface) of the roller, so that the corner-folded piece formed on the other side of the bill is in the upright direction. That is, it is easy to get up in the direction away from the outer peripheral surface of the roller. By this action, the tip portions 56a and 57a of the scrapers 56 and 57 can be reliably hooked on the corner broken pieces deformed in the upright direction, and the corner broken pieces can be corrected flat.
The corner fold straightening device 1 according to the present embodiment has a small number of parts and a simple structure, so that it is possible to reduce the size, simple structure, and cost, and correct all the corner folds on both the front and back sides. can do.

<First embodiment>
The paper leaf corner fold correction device 1 according to the first embodiment is a first curved transport guide member (roller 10, roller 10,) having a curved guide convex surface (outer peripheral surface) in contact with one surface of the paper leaf (banknote 100) to be transported. 20 and 30) and a second curve provided with a curved guide concave surface that guides the other surface of the paper leaf while forming curved paths G1, G2, and G3 that allow the paper leaf to pass in cooperation with the curved guide convex surface. The transport guide members (outer guide members 50, 60, 70) and the corner bending straightening portions 51a, 61a, 61b, 71a provided at the ends of the second curved transport guide member in the transport direction were introduced into the curved path. It is characterized by being provided with transport means (rollers 10, 20, 30) for transporting the paper leaf in both the forward direction and the reverse direction in the curved path.

紙葉（紙幣）の計数、分類・仕分け業務においては、作業の煩雑さの解消、効率化、不正防止等のセキュリティー性向上の為に自動化が望まれている。計数、分類・仕分けを支援する紙葉整理機（紙幣整理機）では角折れ紙葉（紙幣）はリジェクトし、これを作業員が手作業で修正し再計数、再分類・仕分けする必要がある。しかし、角折れ片を伸ばす作業は特に面倒であり効率の低下に繋がっているが、本態様によって自動化が可能となる。
本態様では、一端角隅部に角折れ片を有した紙葉を、湾曲した搬送路に沿って搬送するので、紙葉の搬送方向の端部に位置し他面側に折れた角折れ片を紙葉表面（他面）から離間させることが可能となる。従って、紙葉の他面をガイドする第二湾曲搬送ガイド部材に形成した角折れ矯正部によって、角折れ片の引っ掛け、掬い上げ、引き起こしが確実となり、全体として矯正が確実となる。
このように、紙葉の他面側に折れた角折れ片は、紙葉を、その他面側が凸状に湾曲するように変形させた状態で搬送することによって矯正を確実にできる。逆に、紙葉の一面側に折れた角折れ片を確実に矯正するには、紙葉を、その一面側が凸状に湾曲するように変形させた状態で搬送すればよい。つまり、紙葉の各面側に折れた角折れ片の全てを確実に矯正するには、紙葉が、一面側に凸となる姿勢と他面側に凸となる姿勢の双方をとるようにすればよい。これを実現するためには、例えば、第一湾曲搬送ガイド部材を複数個配置して、湾曲路から成る搬送経路が全体としてＳ字状となるようにするか、単一の第一湾曲搬送ガイド部材内で紙葉の表裏を反転させた状態で搬送するようにすればよい。搬送経路が全体としてＳ字状となるようにすれば、一度の往復搬送で表裏両面の角折れ片をローラ周面から離間する方向へ起こして矯正することが可能となる。 In the counting, sorting and sorting of paper sheets (banknotes), automation is desired in order to eliminate the complexity of the work, improve efficiency, and improve security such as fraud prevention. Paper leaf sorters (banknote sorters) that support counting, sorting, and sorting reject square-folded paper leaves (banknotes), which must be manually corrected by workers for recounting, reclassification, and sorting. .. However, the work of extending the broken piece is particularly troublesome and leads to a decrease in efficiency, but this embodiment enables automation.
In this embodiment, since the paper leaf having a corner fold at one corner is transported along the curved transport path, the corner fold is located at the end of the paper leaf in the transport direction and is folded toward the other side. Can be separated from the paper leaf surface (other surface). Therefore, the corner fold straightening portion formed on the second curved transport guide member that guides the other surface of the paper leaf ensures that the corner fold piece is hooked, scooped up, and raised, and the correction is ensured as a whole.
In this way, the corner-folded pieces folded on the other side of the paper leaf can be reliably corrected by transporting the paper leaf in a deformed state so that the other side is curved in a convex shape. On the contrary, in order to surely correct the broken corner pieces that are broken on one side of the paper leaf, the paper leaf may be conveyed in a state of being deformed so that the one side of the paper leaf is curved convexly. In other words, in order to reliably correct all the corner folds that are folded on each side of the paper leaf, the paper leaf should take both a posture that is convex on one side and a posture that is convex on the other side. do it. In order to realize this, for example, a plurality of first curved transport guide members are arranged so that the transport path composed of the curved paths has an S shape as a whole, or a single first curved transport guide. The paper may be transported in a state where the front and back sides of the paper sheet are inverted in the member. If the transport path is S-shaped as a whole, it is possible to raise and correct the corner-folded pieces on both the front and back surfaces in a direction away from the peripheral surface of the roller in one reciprocating transport.

本実施態様に示す角折れ矯正装置では、紙葉を正方向に搬送したときに紙葉の後端部（搬送方向の上流側端部）に位置する角折れ片が対応する角折れ矯正部によって矯正を受け、紙葉を逆方向に搬送したときに紙葉の先端部（搬送方向の上流側端部）に位置する角折れ片が対応する角折れ矯正部によって矯正を受ける。即ち、一度の往復搬送で、紙葉の先端、後端に位置する角折れ片の双方を矯正できる。
ここで、第一湾曲搬送ガイド部材は、回転するローラであってもよいし、非回転のガイド部材であってもよい（例：湾曲した板状の内側ガイド部材１５）。第一湾曲搬送ガイド部材を回転するローラとした場合には、第一湾曲搬送ガイド部材を搬送手段と兼用できる。
角折れ矯正部は、種々の形状とすることができる。例えば、平面視で遊端側に向けて幅が漸減するテーパー状のエッジ部からなる角折れ矯正部としてもよく、この場合は平面視で直線状のエッジ部としてもよいし、内側へ凹状に湾曲して延びるエッジ部、或いは外側に凸状に湾曲して延びるエッジ部としてもよい。また、ブラシやスクレーパを角折れ矯正部としてもよい。 In the corner fold straightening device shown in the present embodiment, when the paper leaf is transported in the forward direction, the corner fold straightening portion corresponding to the corner fold piece located at the rear end portion (upstream end portion in the transport direction) of the paper leaf is used. When the paper leaf is straightened and transported in the opposite direction, the corner folds located at the tip of the paper leaf (upstream end in the transport direction) are corrected by the corresponding corner fold correction section. That is, both the front end and the rear end of the paper leaf can be corrected by one reciprocating transfer.
Here, the first curved transport guide member may be a rotating roller or a non-rotating guide member (eg, a curved plate-shaped inner guide member 15). When the first curved transport guide member is a rotating roller, the first curved transport guide member can also be used as the transport means.
The corner break correction portion can have various shapes. For example, it may be a corner break correction portion composed of a tapered edge portion whose width gradually decreases toward the free end side in a plan view, and in this case, it may be a straight edge portion in a plan view, or it may be concave inward. It may be an edge portion that is curved and extends, or an edge portion that is curved and extends outward in a convex shape. Further, a brush or a scraper may be used as a corner break correction portion.

本実施態様に示す角折れ矯正装置は、協働して湾曲搬送路を形成する第一及び第二湾曲搬送ガイド部材と、第二湾曲ガイド部材の搬送方向の端部に形成した角折れ矯正部とを備えるので、角折れ矯正装置は部品点数が少なく、構成がシンプルであり、小型化、簡易構造化、低コスト化が可能でありながら、表裏両面の全ての角折れ片を矯正することができる。 The corner fold straightening device shown in the present embodiment includes a first and second curved transport guide members that cooperate to form a curved transport path, and a corner fold straightening portion formed at an end portion of the second curved guide member in the transport direction.
