最初に、図１～図４を参照して、関連する紙幣搬送機構９００の構成について説明する。 First, with reference to FIGS. 1 to 4, the configuration of a related banknote transport mechanism 900 will be described.

図１、図２に示すように、搬送路駆動ギア５０から動力を受けて回転する搬送路駆動軸５２と駆動ローラ５１によって、搬送ベルト６０が回転する。また、搬送ベルト６０の回転により、搬送路途中の軸とローラが回転する。搬送ベルト６０とローラの回転により、図示しない紙幣は第１の搬送ガイド１１０と第２の搬送ガイド１２０の間で搬送される。 As shown in FIGS. 1 and 2, the conveying belt 60 is rotated by the conveying path driving shaft 52 and the driving roller 51 which are rotated by receiving power from the conveying path driving gear 50 . Further, the rotation of the conveying belt 60 rotates the shafts and rollers in the middle of the conveying path. A bill (not shown) is conveyed between the first conveying guide 110 and the second conveying guide 120 by the rotation of the conveying belt 60 and rollers.

紙幣搬送機構９００は、メンテナンスのために各構成部品を分解することが可能である。図３は、第２の搬送ガイド１２０を取り外した状態を示す。図４は、さらに第２の搬送ガイド１２０側の第２の従動ローラ２１および第２の従動ローラ２１のローラ軸２２を取り外した状態を示す。 The banknote transport mechanism 900 can be disassembled into components for maintenance. FIG. 3 shows a state in which the second transport guide 120 is removed. FIG. 4 also shows a state in which the second driven roller 21 on the side of the second transport guide 120 and the roller shaft 22 of the second driven roller 21 are removed.

図３、図４に示すように、搬送ベルト６０に従動する第１の従動ローラ１１のローラ軸１２と第１の搬送ガイド１１０が搬送路のフレーム１００の端から端まで渡っている。このため、第１の従動ローラ１１のローラ軸１２と第１の搬送ガイド１１０が搬送ベルト６０を跨っている構成となっている。この結果、搬送ベルト６０を交換する際には、紙幣搬送機構９００をほぼ全分解しなければならない。 As shown in FIGS. 3 and 4, the roller shaft 12 of the first driven roller 11 driven by the conveying belt 60 and the first conveying guide 110 extend from end to end of the frame 100 of the conveying path. Therefore, the roller shaft 12 of the first driven roller 11 and the first transport guide 110 straddle the transport belt 60 . As a result, when replacing the transport belt 60, the banknote transport mechanism 900 must be almost completely disassembled.

実施例は、搬送ベルト６０の交換時に紙幣搬送機構９００をほぼ全分解しなければならないという関連技術の課題を解決する。以下、図面を用いて実施例について説明する。 The embodiment solves the problem of the related art that the banknote transport mechanism 900 must be substantially completely disassembled when the transport belt 60 is replaced. An embodiment will be described below with reference to the drawings.

図５、図６を参照して、実施例の紙幣搬送機構９００の構成について説明する。
尚、図１、図２に示す構成は、実施例の紙幣搬送機構においても共通しているので、共通する部材には、同じ参照番号が付されている。ここで、図５は関連技術の図３に対応し、図６は関連技術の図４に対応する。 The configuration of the banknote transport mechanism 900 of the embodiment will be described with reference to FIGS. 5 and 6. FIG.
The configurations shown in FIGS. 1 and 2 are also common to the bill transport mechanism of the embodiment, so common members are given the same reference numerals. Here, FIG. 5 corresponds to FIG. 3 of the related art, and FIG. 6 corresponds to FIG. 4 of the related art.

図５、図６に示すように、搬送路駆動ギア５０から動力を受けて回転する搬送路駆動軸５２と駆動ローラ５１によって、搬送ベルト６０が回転する。また、搬送ベルト６０の回転により、搬送路途中の軸とローラが回転する。搬送ベルト６０とローラの回転により、紙幣（図示せず）は第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３と第２の搬送ガイド１２０の間で搬送される。このようにして、第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３と、第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３に対向して配置された第２の搬送ガイド１２０との間で紙幣を搬送する。 As shown in FIGS. 5 and 6 , the transport belt 60 is rotated by the transport path drive shaft 52 and the drive roller 51 which are rotated by receiving power from the transport path drive gear 50 . Further, the rotation of the conveying belt 60 rotates the shafts and rollers in the middle of the conveying path. Bills (not shown) are conveyed between the first divided conveying guide 211, the second divided conveying guide 212, the third divided conveying guide 213, and the second conveying guide 120 by the rotation of the conveying belt 60 and the rollers. be done. In this manner, the first divided conveying guide 211, the second divided conveying guide 212 and the third divided conveying guide 213, the first divided conveying guide 211, the second divided conveying guide 212 and the third divided conveying guide 211 Banknotes are conveyed between them and a second conveying guide 120 arranged to face the conveying guide 213 .

第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３の側には、紙幣の搬送方向に沿って設けられた複数の第１の従動ローラ１１が設けられている。また、複数の第１の従動ローラ１１に跨がって通された搬送ベルト６０が設けられている。第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３の端部には、搬送ベルト６０に駆動力を与える駆動ローラ５１が設けられている。第２の搬送ガイド１２０の側には、紙幣の搬送方向に沿って設けられ、搬送ベルト６０との間で紙幣を挟持して搬送する複数の第２の従動ローラ２１が設けられている。 A plurality of first driven rollers 11 are provided along the banknote conveying direction on the side of the first divided conveying guide 211, the second divided conveying guide 212, and the third divided conveying guide 213. there is Further, a conveying belt 60 is provided that is passed over the plurality of first driven rollers 11 . Drive rollers 51 that apply driving force to the conveyor belt 60 are provided at the ends of the first divided conveying guide 211 , the second divided conveying guide 212 and the third divided conveying guide 213 . On the side of the second transport guide 120, a plurality of second driven rollers 21 are provided along the banknote transport direction, and transport the banknotes while pinching them with the transport belt 60. As shown in FIG.

第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３は、図４に示す第１の搬送ガイド１１０が、第１の従動ローラ１１及び搬送ベルト６０を境にして、紙幣の搬送方向に対して垂直な方向に分割された形態となっている。更に、第１の従動ローラ１１を保持するローラ軸３１２の少なくとも一つの端部は解放されている。 The first divided conveying guide 211, the second divided conveying guide 212, and the third divided conveying guide 213 are arranged so that the first conveying guide 110 shown in FIG. Thus, the banknotes are divided in the direction perpendicular to the direction in which the banknotes are conveyed. Furthermore, at least one end of the roller shaft 312 holding the first driven roller 11 is open.

搬送ベルト６０は、第１の搬送ベルトと第２の搬送ベルトとから構成される。第１の従動ローラ１１は、第１の搬送ベルトと第２の搬送ベルトとがそれぞれ通された一対のローラから構成される。第１の搬送ガイド１１０は、第１の搬送ベルト及び第２の搬送ベルトと一対のローラを境に、紙幣の搬送方向に対して垂直な方向に３つに分割されている。 The transport belt 60 is composed of a first transport belt and a second transport belt. The first driven roller 11 is composed of a pair of rollers through which the first conveying belt and the second conveying belt are respectively passed. The first conveying guide 110 is divided into three sections in a direction perpendicular to the bill conveying direction with the first conveying belt, the second conveying belt, and the pair of rollers as boundaries.

具体的には、図６～図８に示すように、第１の搬送ガイド１１０は、第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３の３つに分割されている。そして、第１の分割搬送ガイド２１１と第２の分割搬送ガイド２１２に間に、第１の搬送ベルトが設けられている。また、第２の分割搬送ガイド２１２と第３の分割搬送ガイド２１３に間に、第２の搬送ベルトが設けられている。 Specifically, as shown in FIGS. 6 to 8, the first conveying guide 110 is divided into three divided conveying guides 211, 212 and 213. split. A first conveying belt is provided between the first divided conveying guide 211 and the second divided conveying guide 212 . A second conveying belt is provided between the second divided conveying guide 212 and the third divided conveying guide 213 .

図１０に示すように、搬送ベルト６０に従動する第１の従動ローラ１１のローラ軸３１２を、搬送路のフレーム１５０の底部の中央部に曲げ起こしたフレーム１５０の曲げ起こし部１５１にかかえる。これにより、第１の従動ローラ１１のローラ軸１２（図１～図４参照）が、第１の従動ローラ１１のローラ軸３１２（図１０参照）へと短尺化されローラ軸の短尺化が実現される。 As shown in FIG. 10, the roller shaft 312 of the first driven roller 11 driven by the conveying belt 60 is held by the bent and raised portion 151 of the frame 150 which is bent and raised at the center of the bottom of the frame 150 of the conveying path. As a result, the roller shaft 12 (see FIGS. 1 to 4) of the first driven roller 11 is shortened to the roller shaft 312 (see FIG. 10) of the first driven roller 11, realizing a shortened roller shaft. be done.

このように、実施例の紙幣搬送機構９００では、第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３の側に、第１の従動ローラ１１を保持するローラ軸３１２を支えるための支持部を有する。この支持部は、フレーム１５０の底面の一部を曲げ起こして成る曲げ起こし部１５１により構成される。 Thus, in the banknote transport mechanism 900 of the embodiment, rollers for holding the first driven roller 11 are provided on the side of the first divided transport guide 211, the second divided transport guide 212, and the third divided transport guide 213. It has a support for supporting the shaft 312 . This support portion is constituted by a bent and raised portion 151 formed by bending and raising a portion of the bottom surface of the frame 150 .

第１の従動ローラ１１を保持するローラ軸３１２の端部は、フレーム１５０の側面とは連結されていない。よって、第１の従動ローラ１１を保持するローラ軸３１２の長さは、フレーム１５０の対向する一対の側面の間の幅よりも短い。この結果、第１の従動ローラ１１のローラ軸３１２の短尺化が実現される。 The end of roller shaft 312 holding first driven roller 11 is not connected to the side surface of frame 150 . Therefore, the length of the roller shaft 312 that holds the first driven roller 11 is shorter than the width between the pair of opposing side surfaces of the frame 150 . As a result, the length of the roller shaft 312 of the first driven roller 11 can be shortened.

上記構成を採用することにより、搬送ベルト６０が、短尺化した第１の従動ローラ１１のローラ軸３１２と、第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３の側面から裏側に通り抜けられる構造になる。 By adopting the above configuration, the conveying belt 60 can be configured to include the roller shaft 312 of the first driven roller 11, which is shortened, the first divided conveying guide 211, the second divided conveying guide 212, and the third divided conveying guide. It becomes a structure that can pass through from the side of 213 to the back side.

このため、搬送路駆動ギア５０から動力を受けて回転する搬送路駆動軸５２と駆動ローラ５１及びその逆端の回転軸である第１の従動ローラ１１のローラ軸１２と第１の従動ローラ１１を取り外すだけで、搬送ベルト６０を交換することができる。 For this reason, the roller shaft 12 and the first driven roller 11 of the first driven roller 11 which is the rotation shaft at the opposite end of the transport path drive shaft 52 and the drive roller 51 which are rotated by receiving power from the transport path drive gear 50 are arranged. The conveyor belt 60 can be replaced by simply removing the .

なお、図６、図１０に示すように、第１の従動ローラ１１のローラ軸１２は搬送路の安定性のために短尺化していない。しかし、第１の従動ローラ１１のローラ軸１２は駆動軸ではないため、短尺化した第１の従動ローラ１１のローラ軸３１２のように短尺化しかつフレーム１５０の曲げ起こし部１５１に抱えた構造であっても良い。この場合、ベルト交換時は搬送路駆動ギア５０から動力を受けて回転する搬送路駆動軸５２と駆動ローラ５１だけを取り外すだけでよくなり作業効率が更に向上する。 Incidentally, as shown in FIGS. 6 and 10, the roller shaft 12 of the first driven roller 11 is not shortened for the stability of the conveying path. However, since the roller shaft 12 of the first driven roller 11 is not a driving shaft, it is shortened like the roller shaft 312 of the first driven roller 11 which is shortened and held by the bent and raised portion 151 of the frame 150 . It can be. In this case, when replacing the belt, it is sufficient to remove only the transport path driving shaft 52 and the drive roller 51 which are rotated by receiving power from the transport path driving gear 50, thereby further improving work efficiency.

さらに、搬送路駆動ギア５０を搬送路の内部に設ける構成を採用することにより、搬送路駆動ギア５０から動力を受けて回転する搬送路駆動軸５２を短尺化し、かつフレーム１５０の曲げ起こし部１５１に抱えた構造であっても良い。この場合、ベルト交換時に搬送路駆動ギア５０から動力を受けて回転する搬送路駆動軸５２と駆動ローラ５１も取り外す必要がなくなるため、一層の作業効率向上が期待できる。 Furthermore, by adopting a configuration in which the transport path driving gear 50 is provided inside the transport path, the transport path driving shaft 52 that receives power from the transport path driving gear 50 and rotates can be shortened, and the bent and raised portion 151 of the frame 150 can be bent. It may be a structure held in In this case, since it is not necessary to remove the transport path driving shaft 52 and the drive roller 51 which are rotated by receiving power from the transport path driving gear 50 when replacing the belt, a further improvement in work efficiency can be expected.

図７は、図６において搬送ベルト６０を取り外した状態を示している。また、図８は、第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３それ自体を示している。 FIG. 7 shows a state in which the conveyor belt 60 is removed from FIG. 8 also shows the first divided conveying guide 211, the second divided conveying guide 212, and the third divided conveying guide 213 themselves.

図７、図８に示すように、図１～図４に示す関連する紙幣搬送機構９００の構成と比べて、第１の搬送ガイド１１０が第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３の３つに分割されていることがわかる。比較参考までに関連する紙幣搬送機構の同一部分の構成を図９に示す。図９に示す関連する機構では、第１の搬送ガイド１１０が一面にまたがっているため、搬送ベルト６０の交換が必ずしも容易でないことがわかる。 As shown in FIGS. 7 and 8, compared to the configuration of the associated banknote transport mechanism 900 shown in FIGS. 212 and a third divided conveying guide 213 . For comparison reference, FIG. 9 shows the configuration of the same portion of the related bill conveying mechanism. In the related mechanism shown in FIG. 9, since the first transport guide 110 spans the entire surface, it can be seen that replacement of the transport belt 60 is not always easy.

図１０は、図７において、第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３を取り除いた状態を示す。 FIG. 10 shows a state in which the first divided conveying guide 211, the second divided conveying guide 212 and the third divided conveying guide 213 are removed in FIG.

図１０に示すように、第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３側の第１の従動ローラ１１のローラ軸３１２が短くなっている。さらに、フレーム１５０の底部の中央部の穴５５０から曲げ起こして構成された曲げ起こし部１５１が短尺化した第１の従動ローラ１１のローラ軸３１２を抱える構造になっている。 As shown in FIG. 10, the roller shaft 312 of the first driven roller 11 on the side of the first divided conveying guide 211, the second divided conveying guide 212, and the third divided conveying guide 213 is shortened. Furthermore, a bent and raised portion 151 formed by bending and raised from a hole 550 in the center of the bottom of the frame 150 has a structure that holds the roller shaft 312 of the first driven roller 11 having a shortened length.

ここで、短尺化した第１の従動ローラのローラ軸３１２を抱えるフレーム１５０の曲げ起こし部１５１とフレームの穴５５０は、フレーム１５０の中央部からでなく、フレーム１５０の側面部等の穴とその穴からの曲げ起こし部であっても良い。 Here, the bent and raised portion 151 of the frame 150 that holds the roller shaft 312 of the first driven roller, which is shortened, and the hole 550 in the frame are formed not from the central portion of the frame 150 but from the side portion of the frame 150 and the like. It may be a bent and raised portion from a hole.

また、第１の従動ローラ１１を保持するローラ軸３１２を支えるための支持部は、フレーム１５０からの曲げ起こし部でなく、図示しない別の部品をフレーム１５０に取り付けた構造であっても良い。 Further, the support portion for supporting the roller shaft 312 holding the first driven roller 11 may be a structure in which another component (not shown) is attached to the frame 150 instead of the bent and raised portion from the frame 150 .

比較参考までに関連する紙幣搬送機構の同一部分の構成を図１１に示す。図１１に示す構成では、第１の搬送ガイド１１０側の第１の従動ローラ１１のローラ軸１２がフレーム１００の側面の端から端までに渡っている。このため、ベルト交換時にベルトを通すことができず、作業が煩雑となる場合があった。 For comparison reference, FIG. 11 shows the configuration of the same portion of the related bill conveying mechanism. In the configuration shown in FIG. 11 , the roller shaft 12 of the first driven roller 11 on the first transport guide 110 side extends from end to end of the side surface of the frame 100 . As a result, the belt cannot be passed through the belt when replacing the belt, and the work becomes complicated in some cases.

上記実施例によれば、搬送ベルト６０を交換する際に、分解しなければならない部品が最小限で済むため、修理時間の大幅短縮ができる。これにより、ユニットを持ち帰らなくても、現地でベルトだけを交換することができる。 According to the above-described embodiment, the number of parts to be disassembled is minimized when replacing the conveyor belt 60, so that the repair time can be significantly shortened. As a result, it is possible to replace only the belt on site without having to bring the unit home.

なお、図５、図６、図７、図８に記載した例では、一対の搬送ベルト６０と、第１の搬送ガイド１１０を３分割して構成した第１の分割搬送ガイド２１１、第２の分割搬送ガイド２１２及び第３の分割搬送ガイド２１３の例を挙げている。しかし、本発明はこれに限定されず、３本の搬送ベルト６０と４分割した第１の搬送ガイド１１０、４本の搬送ベルト６０と５分割した第１の搬送ガイド１１０のように、搬送ベルト６０の数と、第１の搬送ガイド１１０を分割する数が上記実施例と異なっていても良い。 In the examples shown in FIGS. 5, 6, 7, and 8, the pair of conveying belts 60 and the first divided conveying guide 211 configured by dividing the first conveying guide 110 into three; Examples of the divided conveying guide 212 and the third divided conveying guide 213 are given.
