Description

The present invention relates to a paper sheet straightening device capable of a straightening operation for reducing wrinkles and wrinkles occurring in a paper sheet transported by a transport fluid flowing from upstream to downstream.

In the past, when conveying thin plastic or paper cards and bills such as paper money, a paper sheet conveying device that sandwiches the paper sheet with a belt or a roller and sends it out has been known, and it has become popular in the market. ing. For example, in a game arcade where game machines such as pachinko and slot machines are installed, a game medium lending device or the like is provided adjacent to the game machine, without banknotes being stocked in this game medium lending device, A paper sheet transporting device is used when the bills are transported to a bank safe section or the like for management. In the paper sheet conveying device of the game arcade, the bills discriminated by the bill discriminating unit such as the game medium lending device are taken in and attached to the island end of the gaming island where the gaming machine is installed by the conveying mechanism including belts and rollers. Carry to the bank safe.

In such a paper sheet transporting device, since a banknote is sandwiched between a belt and a roller to transport the banknote, there is a problem that the banknote is often jammed at a connecting portion of the belt and the roller. In order to clear a banknote jam, it is necessary for a player who is playing a game on a gaming machine to interrupt the game, identify the defective part on the game island, and remove the jammed banknotes, which causes trouble to customers. At the same time, the burden on the game shop staff was not small.

In recent years, there has been proposed a paper sheet transporting device that transports a banknote by generating a transporting air stream in a transport tube and mounting it on the air stream. If the banknotes are transported by air flow, there is no risk that the banknotes will be jammed in the mechanical parts, because no mechanism such as belts or rollers is used. However, in order to convey a bill by air flow, if the bill has a fold or a bending tendency, the air flow received by the bill becomes irregular and there is a risk that the bill will stop in the conveying pipe. It is proposed that the paper sheet feeding device that feeds the paper sheets into the conveyance pipe of the paper sheet conveyance device (takes in the conveyance pipe side) is provided with a function of correcting habits, wrinkles, and the like that occur in banknotes. (See, for example, paragraphs [0080] to [0082] of Patent Document 1, FIG. 9). The paper sheet fetching device described in Patent Document 1 employs a correction method of extending a fold attached to a bill by passing the bill through a curved passage curved in an S shape.

JP 2012-025510 A

However, with the bill correcting method applied to the paper sheet taking-in device described in Patent Document 1, it is possible to expect only an effect of extending a light fold or the like attached to a bill. Only by passing through such a curved passage, it is not possible to obtain the effect of correcting the strong creases and bending habits fixed on the bill over a long period of time.

In addition, in the paper sheet conveying apparatus described in Patent Document 1, since the conveying auxiliary body is moved by the action of the air flow and the bill is conveyed by the moving conveying auxiliary body, a strong crease or a bending tendency is generated. It is considered possible to carry even the remaining habit cards. However, when an air flow is directly applied to a paper sheet to be conveyed without using an auxiliary tool such as an auxiliary body for conveyance, it is important to make the air flow evenly act on both sides of the bill. It is desirable to sufficiently reduce strong creases and bending habits that occur in bills.

Next, an embodiment of a paper sheet straightening apparatus according to the present invention will be described with reference to the accompanying drawings. As paper sheets, papers with shape retention such as banknotes and documents (excluding tissue papers that do not have shape retention with respect to the transport flow), resin films (plastic banknotes (Including) and thin cards can be applied. The paper sheet straightening device of the present embodiment is provided in the bill feeding device, reduces the habit and wrinkles that have occurred on the paper sheet by the paper sheet straightening device, from the paper sheet feeding device to the paper sheet feeding mechanism. The paper sheets are sent to the carrier tube. In the following description, paper bills will be described as objects to be conveyed. The carrier fluid is not limited to gas, and liquid can be used, but in the following description, air is used as the carrier fluid. Further, in the following description, since the banknote is conveyed while standing in the gravity direction, for convenience, the direction in which the two surfaces of the banknote face is referred to as left or right or side, and the direction of gravity orthogonal to this is referred to as up and down.

The banknote feeding device 1 shown in FIG. 1 is used, for example, in a banknote transport mechanism installed in each game island of a game shop. The bill transport mechanism can be used to collect bills inserted in a game medium lending device, a card selling device, etc. and collect them in one place. The banknotes 3 to be conveyed by passing through the conveying path 2a in the conveying pipe 2 are introduced into the conveying pipe 2 from the bill feeding device 1. A blower 4 is provided at one end of the transport tube 2, and a bill collecting unit 5 is provided at the other end. That is, the air as the transporting fluid flows in the transport pipe 2 from the upstream side where the blower 4 is provided to the downstream side where the bill collecting unit 5 is provided. It should be noted that by providing a suction device on the downstream banknote collecting unit 5 side, it is possible to allow air as a transport fluid to flow from the upstream side to the downstream side in the transport pipe 2. Further, if the transport pipe is folded back at the end to have a substantially U shape, the blower 4 and the bill collecting unit 5 can be provided on the same side.

The transport pipe 2 can be connected to a required length and adjusted to a flow path according to the installation location and situation. The bill feeding device 1 that feeds bills to the conveying pipe 2 receives, for example, the bills 3 fed from the gaming machine device 7 provided corresponding to each gaming machine 6 from the bill introducing path 8, and the bills inside the conveying pipe 2. It is sent to the transport path 2a. The gaming machine 6 is a ball-type gaming machine, a spinning-type gaming machine, or the like, and the gaming machine device 7 lends out a gaming medium according to the type of the connected gaming machine 6 or lends it according to the amount of money inserted. This is a device for issuing a game information recording medium that can be used for renting out a medium.

The bill feeding device 1 is provided with a bill straightening device 10 as a paper sheet straightening device capable of performing a straightening operation for reducing habits and wrinkles that have occurred on paper sheets. The bills 3 received into the bill feeding device 1 from the bill introducing passage 8 are corrected for habits and wrinkles while passing through the bill correcting device 10, and are fed into the conveying passage 2a of the conveying pipe 2. Note that the bill correcting device 10 does not necessarily need to be provided in the bill feeding device 1, and may be provided in any device as long as it is necessary to reduce wrinkles and wrinkles that occur in paper sheets such as bills. .. Further, if the paper sheets to be corrected are manually inserted into the bill correcting device 10 or the bill correcting device 10 is provided with a mechanism for continuously feeding the paper sheets, the bill correcting device 10 can be used as a single device. ..

As shown in FIG. 2, the bill feeding device 1 includes a receiving passage 1a for receiving the bills 3 supplied from the bill introducing passage 8 and a feeding passage 1b for feeding the bills 3 from the bill feeding opening 2b to the conveying passage 2a. A bill correcting device 10 is provided in between. In the banknote straightening device 10, since the banknotes are fed through the straightening process path 10a, a straightening operation is performed to reduce the habits and wrinkles that have occurred on the banknotes 3. Therefore, the banknotes 3 supplied from the straightening process path 10a to the sending flow path 1b are , Strong folds and bending habits are also sufficiently reduced. The straightened bill 3 has no strong creases or bending tendency, and therefore, when fed into the transport path 2a, it does not receive an air flow in an extremely biased direction. The risk that 3 will stick and become impossible to carry is reduced.

Further, the bill feeding device 1 is provided with a bill feeding mechanism for feeding the bills 3 in an appropriate direction. For example, a bill transfer mechanism including a main roller 91 and an auxiliary roller 92 is provided in the vicinity of the bill feeding port 2b on the most downstream side of the feeding flow path 1b. The main roller 91 has a vertically long cylindrical shape with the main shaft 91 a as the center of rotation, and is rotatably arranged with its peripheral surface protruding near the center of the feed flow passage 1 b, and receives a driving force from the drive mechanism 93. Rotate. The auxiliary roller 92 has a vertically long cylindrical shape with the auxiliary shaft 92a as the center of rotation, and is rotatably arranged such that the peripheral surface thereof is in sliding contact with the peripheral surface of the main roller 91 near the center of the feed passage 1b.

When the main roller 91 rotates clockwise (in the direction indicated by the broken line arrow in FIG. 2) by the driving force of the drive mechanism 93, the auxiliary roller 92 rotates in the counterclockwise direction (in the direction indicated by the broken arrow in FIG. 2). .. When the bill 3 is introduced therein and reaches the sliding contact portion between the main roller 91 and the auxiliary roller 92, the bill 3 is sandwiched between the main roller 91 and the auxiliary roller 92 and fed out to the bill feeding port 2b side, and the conveyance path 2a. It is sent in. Such bill transfer mechanisms may be provided at appropriate intervals according to the lengths of the receiving channel 1a and the sending channel 1b.

The bill correcting device 10 receives the bill 3 from the inlet 10c provided on the upstream side of the main body case 10b in which various functions are stored, and ejects the bill 3 from the outlet 10d provided on the downstream side. That is, the most upstream of the straightening process path 10a is the inlet 10c, and the most downstream is the outlet 10d. In the banknote straightening device 10, the banknote is conveyed in a direction from the upstream surface (the surface having the inlet 10c) of the main body case 10b to the downstream surface (the surface having the outlet 10d). .. One direction orthogonal to the transport direction is the first direction, and the other direction is the second direction. In the following description, the first direction is the left and the second direction is the right.

The straightening process path 10a is formed between the left (first direction) edge portion 10a1 and the right (second direction) edge portion 10a2 that are opposed to each other at an appropriate distance on the left and right, and is necessary for passing the banknote 3. Space with sufficient road width. However, the left edge portion 10a1 and the right edge portion 10a2 do not specify the spread of the straightening process path 10a in the left-right direction, but virtually show a conveyance path of equal width from the inlet 10c to the outlet 10d. Is. In practice, since a mechanism for carrying out the correction operation as well as transferring the bills 3 described later is appropriately arranged, the correction process path 10a through which the bills 3 can actually pass is surrounded by the left edge portion 10a1 and the right edge portion 10a2. The area is more limited than the area.

In addition, the correction process path 10a is a meandering path that alternately curves in the left-right direction in order to perform the correction operation described below on the banknote 3. For example, from the upstream side, the right first curve 10aR1 is convex toward the right (second direction) side, the left first curve 10aL1 is convex toward the left (first direction) side, and the right second curve 10aR2 is convex toward the right side. , The left second curve 10aL2 that is convex to the left is a meandering path that curves in this order. The upstream side of the right first curve 10aR1 is connected to the inlet 10c, and the downstream side of the left second curve 10aL2 is connected to the outlet 10d. The meandering shape of the straightening process path 10a is not particularly limited, and may be a meandering path that reciprocates once to the left or right, or may be a long meandering path that repeats more meandering.

The main body case 10b closes the first case portion 11 that opens to the left (first direction) side and the second case portion 12 that opens to the right (second direction) side so that the respective openings face each other. Formed by that. For example, when the first process part 11 and the second process part 12 are divided by the virtual center line of the correction process path 10a, the left edge portion 10a1 of the correction process path 10a faces the opening of the first case part 11 and the correction process The right edge portion 10a2 of the passage 10a faces the opening of the second case portion 12. Thus, in the case where the bill 3 passing through the straightening process path 10a is jammed, the straightening process path 10a can be accessed by opening the first case portion 11 and the second case portion 12, which facilitates maintenance. Increase.

Here, a detailed structure of the bill correcting device 10 according to the first embodiment will be described with reference to FIG. In FIG. 3, the first and second case portions 11 and 12 are shown only by imaginary lines (two-dot chain lines) in schematic positions, and main internal mechanisms are shown by solid lines. FIG. 3A is a diagram of the banknote correction device 10 as viewed from the right (second direction) side. 3B is a cross-sectional view taken along the line IIIB-IIIB in FIG. 3A and is a left first drive roller pair 151L, a right first drive roller pair 151R, a left second drive roller pair 152L, which will be described later. The relationship between the arrangement of the right second drive roller pair 152R and the correction process path 10a is shown. FIG. 3C is a cross-sectional view taken along the line IIIC-IIIC in FIG. 3A and shows a specific structure of a drive mechanism unit 10e described later.

The banknote transfer mechanism of the banknote straightening device 10 is configured to use a plurality of rollers that rotate around an axis that is arranged vertically in a direction orthogonal to the conveyance direction of the banknote 3.

It arrives. The downstream end of the left first guide wall WL1 has an end shape that does not contact the peripheral surface of the left first drive roller 131L1, and the downstream end of the right first guide wall WR1 is the right first driven roller. The end shape is not in contact with the peripheral surface of 141R1.

Further, a left second guide wall WL2 is provided at the left edge portion 10a1 of the straightening process path 10a from the left first drive roller pair 151L to the right first drive roller pair 151R, and the right second guide wall WL2 is also provided at the right edge portion 10a2. A wall WR2 is provided. Therefore, the banknote 3 sent out by the left driving roller pair 151L is guided by the left and right second guide walls WL2, WR2, and slides in the meandering correction process path 10a by the right first driving roller pair 151R. It reaches the department.

Similarly, the upstream end of the right third guide wall WR3 has an end shape that does not contact the peripheral surface of the right first drive roller 131R1, and the downstream end of the right third guide wall WR3 has a right second driven surface. The end portion is not in contact with the peripheral surface of the roller 142R1.

The roller on the downstream right side of the left second drive roller pair 152L is arranged on the right side of the straightening process path 10a, and the cylindrical peripheral surface faces the center portion in the width direction of the straightening process path 10a and rotates by receiving the driving force. The right second drive roller 132R1 rotates about the shaft 132R. The roller on the left side of the downstream side of the second left drive roller pair 152L is disposed on the left side of the straightening process path 10a, and the cylindrical peripheral surface is in sliding contact with the right second drive roller 132R1 at the center portion in the width direction of the straightening process path 10a. The left second driven roller 142L1 which receives the driving force of the right second driving roller 132R1 and rotates around the rotation shaft 142L. The combination of the right second drive roller 132R1 and the left second driven roller 142L1 slidingly contacting the right second drive roller 132R1 is the right second drive roller pair 152R, and the left (first direction) side is downstream of the above-described left second drive roller pair 152L. The curve is convex (corresponding to the left second curve 10aL2 in FIG. 2).

Further, a left fourth guide wall WL4 is provided on the left edge portion 10a1 of the straightening process path 10a from the left second drive roller pair 152L to the right second drive roller pair 152R, and the right fourth guide wall WL4 is also provided on the right edge portion 10a2. The wall WR4 is provided. Therefore, the bill 3 sent out by the left second drive roller pair 152L is guided by the left and right fourth guide walls WL4, WR4, and moves in the meandering correction process path 10a within the right second drive roller pair 152R. It reaches the sliding contact part. The upstream end of the left fourth guide wall WL4 has an end shape that does not contact the peripheral surface of the left second drive roller 132L1, and the downstream end of the left fourth guide wall WL4 has an end shape of the left second driven roller 142L1. The shape of the end does not contact the peripheral surface. Similarly, the upstream end of the right fourth guide wall WR4 has an end shape that does not contact the peripheral surface of the right second driven roller 142R1, and the downstream end of the right fourth guide wall WR4 has the right second drive. The end shape is such that it does not contact the peripheral surface of the roller 132R1.

Further, a left fifth guide wall WL5 is provided on the left edge 10a1 of the straightening process path 10a extending from the discharge port 10d to the right second drive roller pair 152R, and a right fifth guide wall WR5 is also provided on the right edge 10a2. .. Therefore, the banknote 3 sent out by the right second drive roller pair 152R is guided by the left and right fifth guide walls WL5, WR5 and reaches the discharge port 10d in the meandering correction process path 10a. The upstream end of the left fifth guide wall WL5 has an end shape that does not contact the peripheral surface of the left second driven roller 142L1, and the upstream end of the right fifth guide wall WR5 is the right second drive roller. The end portion is not in contact with the peripheral surface of 132R1.

As described above, the left first drive roller pair 151L, the right first drive roller pair 151R, the left second drive roller pair 152L, and the right second drive roller pair 152R are arranged in this order, and the drive rollers of each drive roller pair are arranged. By rotating the bill 3 in an appropriate direction, the bill 3 can be sent from the inlet 10c to the outlet 10d. A rolling effect is exerted on the bills 3 passing through the respective drive roller pairs during this conveyance, so that the folds and bending habits generated on the bills 3 are eliminated to some extent. However, it is difficult to eliminate strong creases and bending habits generated in the bill 3 only by the rolling effect.

Therefore, the feeding speed of each drive roller pair is not made uniform, and the feeding speed is set to be higher for the downstream drive roller pair, so that both sides of the banknote 3 passing through the upstream drive roller pair are formed on the roller peripheral surfaces. Apply rubbing and ironing. This ironing process becomes a correction operation, and strong folds and bending habits generated in the banknote 3 can be efficiently reduced only by passing through the correction process path 10a of the banknote correction device 10. When performing ironing, if the frictional resistance of the upstream roller peripheral surface is high, there is a risk of tearing the banknote 3 when the banknote 3 is pulled in at the speed of the downstream roller, so the roller peripheral surface has low frictional resistance and slips. It is desirable to use a material having good properties (for example, a fluororesin film). Further, control of the delivery speed of the drive roller pair is not particularly limited, and each drive roller may be individually driven so that the delivery speed becomes higher for the drive roller pair on the downstream side. If the structure of 10e is used, one drive source DS can perform suitable speed control.

In the banknote straightening device 10, the rotation shafts 131L, 131R, 132L, and 132R of all the drive rollers are not provided in a straight line in the transport direction, but are provided left and right (first direction or second direction) so that the rotation shafts are gently provided. A meandering straightening process path 10a was formed. If the rotation axes of all the drive rollers are arranged in a straight line, the right half peripheral surface of the left first drive roller 131L1, the left half peripheral surface of the right first drive roller 131R1, the right left peripheral surface of the left second drive roller 132L1, The virtual straightening process path that passes through the left half peripheral surface of the right second drive roller 132R1 is a strong curved path. When the banknote 3 is passed through a strong curved path, a strong right warp and a strong left warp are alternately repeated, so that excessive stress is applied to the banknote and the warp remains, which may cause a paper jam. .. On the other hand, since the straightening process path 10a of the bill correcting path 10 is a gently curved path, it is possible to realize an appropriate straightening operation without giving extra stress to the bill 3. In addition, if the rotation axes of the drive rollers and the driven rollers are shifted to the left and right to form a staggered arrangement, the density of the rollers in the conveyance direction can be increased, so that the bill correction device 10 can be arranged in the conveyance direction. The size can be shortened and the number of drive roller pairs can be increased.

Further, in each drive roller pair, the rotation shaft of the drive roller and the rotation shaft of the driven roller are separately supported by the first case portion 11 or the second case portion 12. Specifically, the rotation shaft 131L of the left first drive roller 131L1, the rotation shaft 141L of the left first driven roller 141L1, the rotation shaft 132L of the left second drive roller 132L1, and the rotation of the left second driven roller 142L1. The shaft 142L is pivotally supported by the first case portion 11. On the other hand, the rotary shaft 141R of the right first driven roller 141R1, the rotary shaft 131R of the right first drive roller 131R1, the rotary shaft 142R of the right second driven roller 142R1, and the rotary shaft 132R of the right second drive roller 132R1 are It is pivotally supported by the second case portion 12. Therefore, when the first case portion 11 and the second case portion 12 are opened, they are separated at the sliding contact portion between the drive roller and the driven roller in each drive roller pair, and the correction process path 10a can be accessed to remove clogging or cleaning work. Maintainability can be improved. Further, even if the first case portion 11 and the second case portion 12 are opened, the pivotal support state of the rotating shafts of all the rollers is maintained, so that the first case portion 11 and the second case portion 12 are again positioned at proper positions. When closed by, the arrangement state of each drive roller pair is restored, and the bill 3 can be conveyed.

As described above, when the left first drive roller pair 151L, the right first drive roller pair 151R, the left second drive roller pair 152L, and the right second drive roller pair 152R are arranged in this order from the upstream side, The directions of rotation are not the same. The drive roller rotatably supported on the first case portion 11 side and the drive roller rotatably supported on the second case portion 12 side are adjacent to each other. The banknotes 3 cannot be sent out in a fixed direction unless the direction in which the roller on the side is rotated is reversed in an alternating manner.

In the left first drive roller pair 151L located on the most upstream side, when the left first drive roller 131L1 rotates counterclockwise (in the direction of the arrow in FIG. 3B), the right first driven roller 141R1 rotates clockwise. The banknote 3 can be delivered downstream by rotating in the direction of the arrow in FIG. 3B. In the right first drive roller pair 151R located downstream of the left first drive roller pair 151L, when the right first drive roller 131R1 rotates clockwise (in the direction of the arrow in FIG. 3B), the left first driven roller is driven. The roller 141L1 rotates counterclockwise (in the direction of the arrow in FIG. 3B), and the banknote 3 can be sent downstream. Thus, the rotation directions of the adjacent left first drive roller 131L1 and adjacent right first drive roller 131R1 are opposite.

In the left second drive roller pair 152L located downstream of the right first drive roller pair 151R, when the left second drive roller 132L1 rotates counterclockwise (in the direction of the arrow in FIG. 3B), the right second drive roller 132L1 rotates. The driven roller 142R1 rotates clockwise (in the direction of the arrow in FIG. 3B), and the banknote 3 can be sent downstream. Therefore, the rotation directions of the right first drive roller 131R1 and the left second drive roller 132L1 that are adjacent to each other are opposite.

In the right second drive roller pair 152R located downstream of the left second drive roller pair 152L, when the right second drive roller 132R1 rotates clockwise (in the direction of the arrow in FIG. 3B), the left second driven roller 132R1 is driven. The roller 142L1 rotates counterclockwise (in the direction of the arrow in FIG. 3B), and the banknote 3 can be sent downstream. Therefore, the rotation directions of the left second drive roller 132L1 and the right second drive roller 132R1 that are adjacent to each other are opposite.

As described above, when the left first drive roller pair 151L, the right first drive roller pair 151R, the left second drive roller pair 152L, and the right second drive roller pair 152R are arranged in this order from the upstream side, each drive roller is FIG. 3C shows a drive mechanism unit 10e that rotates the drive mechanism in an appropriate direction.

The drive source DS drives the rotary shaft 132R of the right second drive roller 132R1, which is the most downstream drive roller that rotates at the highest speed. Although the rotary shaft 132R may be directly driven by the drive source DS, in the drive mechanism section 10e, the small right second drive roller active gear provided on the rotary shaft 132R is provided via the drive gear of the drive source DS. The driving force is transmitted to 132R2. Therefore, the right second drive roller active gear 132R2 that receives the drive force of the drive gear of the drive source DS rotates clockwise (in the direction of the arrow in FIG. 3C), and the rotation shaft 132R and the right second drive roller 132R2 rotate. 132R1 also rotates clockwise. This coincides with the rotation direction when the banknote 3 is sent from the upstream side to the downstream side by the right second drive roller pair 152R.

The right second drive roller active gear 132R2 meshes with the large-diameter left second drive roller passive gear 132L3 provided on the rotary shaft 132L of the left second drive roller 132L1. As a result, when the right second drive roller active gear 132R2 rotates clockwise, the left second drive roller passive gear 132L3 rotates counterclockwise (in the direction of the arrow in FIG. 3C), and the rotation shaft 132L and The left second drive roller 132L1 also rotates counterclockwise. This coincides with the rotation direction when the banknote 3 is sent from the upstream side to the downstream side by the left second drive roller pair 152L. Moreover, since the small-diameter right second drive roller active gear 132R2 is meshed with the large-diameter left second drive roller passive gear 132L3, the rotational speed of the left second drive roller 132L1 is changed by the gear ratio. The rotation speed becomes lower than the rotation speed of the right second drive roller 132R1. Further, the rotation shaft 132L is provided with a left second drive roller active gear 132L2 having a small diameter, and rotates counterclockwise integrally with the left second drive roller passive gear 132L3.

The left second drive roller active gear 132L2 meshes with the large-diameter right first drive roller passive gear 131R3 provided on the rotary shaft 131R of the right second drive roller 131R1. As a result, when the left second drive roller active gear 132L2 rotates counterclockwise, the right first drive roller passive gear 131R3 rotates clockwise (in the direction of the arrow in FIG. 3C), and the rotation shaft 131R and The right first drive roller 131R1 also rotates clockwise. This coincides with the rotation direction when the banknote 3 is sent from the upstream side to the downstream side by the right first drive roller pair 151R. Moreover, since the small-diameter left second drive roller active gear 132L2 is meshed with the large-diameter right first drive roller passive gear 131R3, the rotation speed of the right first drive roller 131R1 is increased by an amount corresponding to the gear ratio. It becomes slower than the rotation speed of the left second drive roller 132L1. Further, a small-diameter right first drive roller active gear 131R2 is provided on the rotary shaft 131R, and rotates clockwise together with the right first drive roller passive gear 131R3.

The right first drive roller active gear 131R2 meshes with the large-diameter left first drive roller passive gear 131L3 provided on the rotary shaft 131L of the left first drive roller 131L1. As a result, when the right first drive roller active gear 131R2 rotates clockwise, the left first drive roller passive gear 131L3 rotates counterclockwise (in the direction of the arrow in FIG. 3C), and the rotation shaft 131L and The left first drive roller 131L1 also rotates counterclockwise. This coincides with the rotation direction when the banknote 3 is sent from the upstream side to the downstream side by the left first drive roller pair 151L. Moreover, since the small-diameter right first drive roller active gear 131R2 is meshed with the large-diameter left first drive roller passive gear 131L3, the rotation speed of the left first drive roller 131L1 is changed by the gear ratio. The rotation speed becomes lower than the rotation speed of the right first drive roller 131R1.

That is, in the drive mechanism section 10e, a large-diameter passive gear provided on the rotary shaft of the drive roller located upstream is meshed with a small-diameter active gear provided on the rotary shaft of the drive roller located downstream. Thus, the driving force can be transmitted such that the rotational speed becomes slower toward the upstream drive roller. Further, it is desirable that the driving force of the driving source DS be applied to the most downstream driving roller that needs to be rotated at the highest speed. Further, since the drive shaft 132R of the right second drive roller 132R1 located on the most downstream side is pivotally supported on the second case portion 12 side, it is desirable that the drive source DS is also provided on the first case portion 12 side. ..

Further, an opening/closing mechanism 10f having a hinge structure is provided on the downstream side of the main body case 10b of the bill correcting device 10 (for example, in the vicinity of the discharge port 10d). The opening/closing mechanism 10f fixes the left (first direction) side support arm portion 10f2L that is rotatable with respect to the shaft support portion 10f1 to the first case portion 11 and rotates the right (second direction) with respect to the shaft support portion 10f1. The (direction) side support arm portion 10f2R is fixed to the second case portion 12. Accordingly, from the closed state (see FIG. 4A) in which the first case portion 11 and the second case portion 12 are closed, the upstream side of the first case portion 11 and the second case portion 12 with the shaft support portion 10f1 as a fulcrum. Can be converted to an open state in which the upstream side of the is expanded (see FIG. 4B). At this time, the left first to fifth guide walls WL1 to WL5 are opened together with the first case portion 11, and the right first to fifth guide walls WR1 to WR5 are opened together with the second case portion 12.

Further, in the first case portion 11, the rotation shaft 131L of the left first drive roller 131L1, the rotation shaft 141L of the left first driven roller 141L1, the rotation shaft 132L of the left second drive roller 132L1, and the left second driven roller. The rotation shaft 142L of the roller 142L1 is pivotally supported. Therefore, the left first drive roller passive gear 131L3, the left second drive roller active gear 132L2, and the left second drive roller passive gear 132L3 open together with the first case portion 11. On the other hand, in the second case portion 12, the rotary shaft 141R of the right first driven roller 141R1, the rotary shaft 131R of the right first drive roller 131R1, the rotary shaft 142R of the right second driven roller 142R1, and the right second drive. A rotation shaft 132R of the roller 132R1 is pivotally supported. Therefore, the right first drive roller active gear 131R2, the right first drive roller passive gear 131R3, and the right second drive roller active gear 132R2 open together with the second case.

At this time, since the opening/closing mechanism 10f is provided on the downstream side of the main body case 10b in which the drive source DS of the drive mechanism section 10e is provided, when the open state is set, the separation of each active roller and the passive roller is performed from the upstream side. In the closed state, the engagement between the active roller and the passive roller is performed from the downstream side. For example, as shown in FIG. 5(A), when the open state is changed to the closed state, the right second drive roller active gear 132R2 on the second case portion 12 side is locked to the drive source DS (restrained so as not to rotate freely). However, the left second drive roller passive gear 132L3 is free (freely rotatable). Therefore, the left second drive roller passive gear 132L3 rotates so as to be aligned with the tooth row position of the right second drive roller active gear 132R2, and meshes reasonably (see FIG. 5B).

When the main body case 10b is brought closer to the closed state, the left second drive roller active gear 132L2 and the right first drive roller passive gear 131R3 mesh with each other. At this time, by engaging the right second drive roller active gear 132R2 and the left second drive roller passive gear 132L3, the left second drive roller active gear 132L2 is locked, but the right first drive roller passive gear 131R3 is free. Is. Therefore, the right first drive roller passive gear 131R3 rotates so as to be aligned with the tooth row position of the left second drive roller active gear 132L2, and meshes reasonably.

When the main body case 10b is brought closer to the closed state, the right first drive roller active gear 131R2 and the left first drive roller passive gear 131L3 mesh with each other. At this time, the right first drive roller active gear 131R2 is locked by the left drive roller active gear 132L2 meshing with the right first drive roller passive gear 131R3, but the left first drive roller passive gear 131L3 is free. .. Therefore, the left first drive roller passive gear 131L3 rotates so as to be aligned with the tooth row position of the right first drive roller active gear 131R2, and meshes reasonably, so that the main body case 10b can be completely closed (FIG. 5). (See (C)).

As described above, if the opening/closing mechanism 10f is provided on the downstream side of the main body case 10b and the state conversion is performed with the downstream side of the first case portion 11 and the second case portion 12 as the fulcrum, the tooth row of the gear is damaged. It becomes possible to separate/engage each passive gear and each active gear without any need. If the drive source is provided on the upstream side and the drive force is applied to the drive roller on the most upstream side, the drive roller on the most upstream side is locked, so the opening/closing mechanism is provided on the upstream side. The downstream side of the first and second case portions 11 and 12 may be expanded. If the opening/closing mechanism 10f has a structure in which the left side support arm 10f2L and the right side support arm 10f2R are separable from each other, after opening the first case part 11 and the second case part 12, the first case part 11 and the first case part 11 are opened. The two case portions 12 can be completely separated, and the maintenance efficiency can be further improved.

In the bill correcting device 10 shown as the first embodiment, the left first to fifth guide walls WL1 to WL5 provided in the first case portion 11 and the right first to fifth guide walls provided in the second case portion 12 are provided. The correction process path 10a for transporting the banknote 3 is formed by WR1 to WR5. However, since each guide wall needs to be arranged so as not to contact the peripheral surface of each roller, a gap is created between each guide wall and each roller main surface. Unless this gap is made narrower than the thickness of the banknotes (about 0.1 mm for Japanese banknotes), the edges of the banknotes 3 may get stuck in this gap, making it impossible to carry or tearing. There is a nature. Therefore, the bill correcting device 10' of the second embodiment shown in FIGS. 6 and 7 is provided with a guide structure in which a gap does not occur in the conveying direction of the bill 3 in the correcting process path 10a. In the banknote straightening device 10', the same structures as those of the banknote straightening device 10 of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 6A shows a roller arrangement and a gear arrangement when the banknote straightening device 10′ is viewed from the right (second direction) side, and FIG. 6B shows the banknote straightening device 10′ left (first direction). ) Side view showing the roller arrangement and the gear arrangement.

All the left rollers pivotally supported by the first case portion 11 are provided with first to fourth guide-removing recesses GR1 to GR4 which are evenly recessed over the entire circumference of the roller peripheral surface. It is provided at a portion corresponding to the arrangement regions 16L1 to 16L4. The left first to fourth guide disposition areas 16L1 to 16L4 are linear areas orthogonal to the rotation shafts 131L, 141L, 132L, 142L pivotally supported on the first case portion 11 side (the conveyance direction of the bill 3). And a left guide rib 17L, respectively. For example, the left first guide arrangement area 16L1 is provided slightly below the top end TE through which the upper part of the short side of the bill 3 passes, the left second guide arrangement area 16L2 is provided below it, and the left third guide arrangement is provided further below. The left fourth guide arrangement region 16L4 is provided in the region 16L3, slightly above the bottom end BE through which the lower portion of the short side of the bill 3 passes.

In the left first guide arrangement area 16L1 of the left first drive roller 131L1, the left first driven roller 141L1, the left second drive roller 132L1, and the left second driven roller 142L1, up to the rotation shafts 131L, 141L, 132L, 142L. The recessed first guide removal recess GR1 is provided. Similarly, in the left second guide disposition region 16L2 of each left roller, the second guide dislocation recess GR2 is provided, in the left third guide disposition region 16L3, the third guide disposition recess GR3 is provided, and at the left fourth guide disposition region. In 16L4, the fourth guide retaining recess GR4 is provided. The first to fourth guide-removing recesses GR1 to GR4 do not necessarily have to be recessed to the rotation shafts 131L, 141L, 132L, 142L, and a small-diameter roller portion may remain on the outer periphery of the rotation shaft. ..

The formation position of the left guide disposition region for providing the left guide rib 17L is not limited to four, and may be two to three or five or more. However, since a guide evacuating recess is formed in the left guide disposition area, the peripheral surfaces of all the left rollers cannot contact the banknote 3 in the left guide disposition area, and the banknote 3 cannot be ironed. There will be no part. In particular, if a fold line parallel to the longitudinal direction of the banknote 3 is made and the position where the fold line is formed coincides with the left guide disposition region, even if the banknote 3 passes through the correction process path 10a, The folds will be discharged without correction. Therefore, it is desirable to prevent the guide-removing recesses GR1 to GR4 from being formed in a highly probable portion where a fold parallel to the longitudinal direction of the banknote 3 is formed.

When folding a bill, it is assumed that the fold is about 1/2 fold, 1/4 fold, or 1/8 fold. For example, assuming that the short side width of the banknote 3 (in the banknote straightening device 10, the length from the top end TE to the bottom end BE) is S, when the ⅛ fold is made, the banknote 3 has S/S. Every 8th, 7 fold lines are generated as fold lines. Therefore, the portions through which the polygonal lines pass in the transport direction are designated as the first to seventh guide-removal formation prohibited basins KA1 to KA7, and the left first to first avoid these first to seventh guide-removal formation prohibited basins KA1 to KA7. The fourth guide disposition areas 16L1 to 16L4 may be provided.

In the bill correcting device 10', the left first guide disposition area 16L1 is provided between the top end TE and the first guide avoidance formation prohibited area KA1. A left second guide disposition area 16L2 is provided between the second guide shredding formation prohibited area KA2 and the third guide shredding formation prohibited area KA3. The left third guide disposition area 16L3 is provided between the fifth guide shank formation prohibited area KA5 and the sixth guide shank formation prohibited area KA6. The left fourth guide disposition region 16L4 is provided between the seventh guide shank formation inhibition region KA7 and the bottom end portion TB. In this way, if the left first to fourth guide disposition areas 16L1 to 16L4 are provided while avoiding the first to seventh guide avoidance formation prohibited basins KA1 to KA7, the banknote 3 with the ⅛ fold is inserted. However, the folding tendency can be sufficiently reduced.

In addition, it is rare that a fold line is made parallel to the long side direction with respect to the banknote 3, and much more rare that a 1/8 fold line in the long side direction is made. It is practical enough if it can handle up to 4 folds. When corresponding to the 1/4 fold in the long side direction, the left guide disposition area is avoided by avoiding the second guide exclusion formation prohibited area KA2, the fourth guide exclusion formation prohibited area KA4, and the sixth guide exclusion formation prohibited area KA6. It should be provided.

The second case portion 12 side also corresponds to the roller structure on the first case portion 11 side described above. All the right rollers pivotally supported by the second case portion 12 are provided with first to fourth guide-removing recesses GR1 to GR4 that are evenly recessed over the entire circumference of the roller peripheral surface. It is provided in each of the regions corresponding to the arrangement regions 16R1 to 16R4. The right first to fourth guide disposition regions 16R1 to 16R4 are linear regions orthogonal to the rotary shafts 141R, 131R, 142R, and 132R pivotally supported on the second case portion 12 side (the conveyance direction of the bill 3). And a right guide rib 17R, respectively. For example, the right first guide disposition region 16R1 is located slightly below the top end TE, the right second guide disposition region 16R2 is located below it, and the right third guide disposition region 16R3 is located below it, and the bottom end part BE of the bottom end BE is located. The right fourth guide disposition region 16R4 is provided slightly above. The right first to fourth guide arrangement regions 16R1 to 16R4 are provided at positions facing the left first to fourth guide arrangement regions 16L1 to 16L4, respectively, so that the right guide rib 17R and the left guide rib 17L face each other. It is desirable to arrange them. Of course, if avoiding the first to seventh guide avoidance formation prohibited basins KA1 to KA7, the right first to fourth guide disposition areas 16R1 to 16R4 and the left first to fourth guide disposition areas 16L1 to 16L4 are formed. It may be arranged differently.

In the right first driven roller 141R1, the right first drive roller 131R1, the right second driven roller 142R1, and the right second drive roller 132R1 in the right first guide disposition region 16R1, up to the rotation shafts 141R, 131R, 142R, 132R. The recessed first guide removal recess GR1 is provided. Similarly, in the right second guide arrangement region 16R2 of each right roller, the second guide removal recess GR2 is formed, in the right third guide arrangement region 16R3, the third guide removal recess GR3 is formed, and in the right fourth guide arrangement region. In 16R4, the fourth guide retaining recess GR4 is provided. The first to fourth guide-removing recesses GR1 to GR4 do not necessarily have to be recessed to the rotating shafts 141R, 131R, 142R, 132R, and a small-diameter roller portion may remain on the outer periphery of the rotating shaft. ..

The formation position of the right guide disposition region for providing the right guide rib 17R is not limited to four, and may be two to three or five or more.

The left side ends of the right first to fifth mounting leg portions 17R1a to 17R1e are continuous in the transport direction, and are located in the left direction (corresponding to the innermost portion of the guide evacuating recess portions GR1 to GR4) (correction process path). The edge projecting toward 10a is the meandering right guide edge 17R3. When the right guide rib 17R is fixed to the second case portion 12 via the first to fifth mounting leg portions 17R1a to 17R1e, the right guide edge 17R3 is the right edge of the straightening process path 10a shown in FIG. The arrangement matches the portion 10a2. That is, it is a meandering shape from the first concave edge portion 17R3a to the second convex edge portion 17R3d through the first convex edge portion 17R3b and the second concave edge portion 17R3c (see FIG. 7B).

As described above, when the first case portion 11 in which the left guide rib 17L is arranged and the second case portion 12 in which the right guide rib 17R is arranged are closed, the left first to fourth guide arrangement regions 16L1 to 16L4 are formed. The right first to fourth guide disposition regions 16R1 to 16R4 face each other. That is, the left guide edge 17L3 of the left guide rib 17L provided in the left first to fourth guide arrangement regions 16L1 to 16L4 and the right guide rib provided in the right first to fourth guide arrangement regions 16R1 to 16R4. The right guide edge 17R3 of 17R opposes. Therefore, when the first case portion 11 provided with the left guide rib 17L and the second case portion 12 provided with the right guide rib 17R are closed, the banknote 3 introduced from the introduction port 10c moves the roller sliding contact portion of each drive roller pair. A straightening process path 10a that is guided to the discharge port 10d is formed (see FIG. 7A).

Further, the bill correcting device 10' is also provided with the opening/closing mechanism 10f, and from the closed state in which the first case portion 11 and the second case portion 12 are closed (see FIG. 7A), the first case portion 11 The upstream side and the upstream side of the second case portion 12 can be converted into an opened state (see FIG. 7B) in which the upstream side is expanded. At this time, the left guide rib 17L opens with the first case portion 11, and the right guide rib 17R opens with the second case portion 12. The left guide rib 17L and the right guide rib 17R may be detachable by a simple operation without being fixed to the first and second cases 11 and 12.

The roller passive gear 132L3 opens together with the first case portion 11. Similarly, the right first drive roller active gear 131R2 and the right first drive roller passive gear 131R3 pivotally attached to the rotary shaft 131R, and the right second drive roller active gear 132R2 pivotally attached to the rotary shaft 132R are Open with two cases. Therefore, also in the bill correcting device 10', if the drive source is provided on the downstream side and the state conversion is performed with the downstream side of the first case portion 11 and the second case portion 12 as the fulcrum, the tooth row of the gear may be damaged. Instead, each passive gear and each active gear can be separated and meshed.

According to the bill correcting devices 10 and 10' according to the first and second embodiments, it is possible to sufficiently reduce strong creases and bending habits generated in the paper sheets, but the meandering correction process path 10a. There is a concern that a warp phenomenon may occur in which the paper sheets that have passed through and are curled in the first direction or the second direction. The reason why the paper sheet warps is considered to be due to various factors such as the holding pressure of the paper sheet by the roller, the rotation speed of the roller, and the meandering condition of the straightening process path 10a. To be Although it is a design matter to perform an appropriate correction operation for the paper sheet and the roller arrangement and the speed adjustment so that the paper sheet does not warp, the trial and error is difficult. Therefore, in the bill correcting device 10″ of the third embodiment shown in FIG. 8, a correction function is added to eliminate the warp generated on the paper sheet by performing the correcting operation. In regard to the same structures as those of the bill correcting devices 10 and 10' of the first and second embodiments, the same reference numerals are given and the description thereof will be omitted.

The banknote straightening device 10″ is provided with a correction roller pair 18 in place of the right second drive roller pair 152R in the banknote straightening device 10′ of the second embodiment. Therefore, in the banknote straightening device 10″, The roller pair for performing the correction operation on the bill 3 introduced from the inlet 10c is the left first drive roller pair 151L, the right first drive roller pair 151R, and the left second drive roller pair 152L. Of these, the left second drive roller pair 152L located on the most downstream side in the transport direction is the most downstream drive roller pair, the left second drive roller 132L1 is the drive roller of the most downstream drive roller pair, and the right second driven roller 142R1 is It becomes the driven roller of the most downstream drive roller pair. Even if the right second drive roller pair 152R is used as it is as the most downstream drive roller pair, and the correction roller pair 18 is further added on the downstream side, a correction function for eliminating the warp generated in the banknote 3 can be realized. ..

The correction roller pair 18 is in sliding contact with the correction drive roller 18R1 that rotates around the rotary shaft 18R in response to the drive force from the drive source DS, and the peripheral surface of the correction drive roller 18R1. This is a combination with the correction driven roller 18L1 that receives and rotates about the rotation shaft 18L. Then, the correction drive roller 18R1 rotates in the same direction as the right second drive roller 132R1 of the right second drive roller pair 152R described above, and the correction driven roller 18L1 rotates the second left side of the right second drive roller pair 152R described above. It rotates in the same direction as the driven roller 142L1. Therefore, the banknote 3 delivered by the left second drive roller pair 152L, which is the most downstream drive roller pair, is further delivered by the correction roller pair 18 to the downstream side in the conveying direction and is ejected from the ejection port 10d.

However, the correction roller pair 18 is not disposed in a staggered arrangement such as the left first drive roller pair 151L, the right first drive roller pair 151R, and the left second drive roller pair 152L, but the left second drive roller pair 152L. They are arranged substantially parallel to the downstream side of the conveyance direction. Specifically, the tangent direction at the sliding contact portion between the correction driving roller 18R1 and the correction driven roller 18L1 of the correction roller pair 18 is the tangential direction at the sliding contact portion between the left second drive roller 132L1 and the right second driven roller 142R1. The correction roller pair 18 is arranged so as to coincide with. Thus, a linear correction process path 10g reaching the discharge port 10d is formed in the tangential direction at the sliding contact portion between the drive roller and the driven roller of the most downstream drive roller pair.

When determining the arrangement position of the correction roller pair 18 so that the correction process path 10g can be formed, if the roller diameters of the left second drive roller pair 152L and the correction roller pair 18 are all the same, the most downstream drive roller. The correction roller pair 18 may be arranged parallel to the most downstream drive roller pair on the downstream side in the tangential direction at the sliding contact portion between the pair of drive rollers and the driven roller. However, when the roller diameters of the left second drive roller pair 152L and the correction roller pair 18 are not all the same, a simple parallel arrangement of the correction roller pair 18 causes a deviation. It is desirable to determine the arrangement position of the correction roller pair 18. Then, in accordance with the arrangement position of the correction roller pair 18, the right fourth guide shaft recess 17R2″ of the right guide rib 17R″ is a shallow recess, and the left fourth drive shaft recess recess 17L2d″ of the left guide rib 17L″ is a deep recess. The rotation of the correction driving roller 18R1 and the correction driven roller 18L1 is not disturbed.

Further, the drive source for driving the correction roller pair 18 may be provided separately from the drive source DS that moves the left first drive roller pair 151L, the right first drive roller pair 151R, and the left second drive roller pair 152L in an interlocking manner. It is good, but the drive mechanism 10e″ of the bill correcting device 10″ shares the drive source DS. For example, the correction roller active gear 18R2 is attached to the rotary shaft 18R of the correction drive roller 18R1 and the correction active gear 18R2 is directly or indirectly rotated by the driving force of the drive source DS. The correction active gear 18R2 is meshed with the left second drive roller passive gear 132L3″ of the left second drive roller pair 152L, and is interlocked with the rotation of the correction drive roller 18R1 so that the left second drive roller 132L1 and the right first drive are driven. The roller 131R1 and the left first drive roller 131L1 are moved in unison. At this time, the left second drive roller passive gear 132L3″ has a gear ratio such that the left second drive roller passive gear 132L3″ rotates slower than the correction active gear 18R2. The feed speed of the correction roller pair 18 is faster than the feed speed of the second drive roller pair 152L.

As described above, by making the feed speed of the correction roller pair 18 higher than that of the left second drive roller pair 152L, the ironing process is performed when the banknote 3 is conveyed on the correction process path 10g. However, since the correction process path 10g is formed in the tangential direction in the sliding contact portion between the left second drive roller 132L1 and the right second driven roller 142R1, the bill 3 is moved to the right or the same as the correction process path 10a. The ironing process is not performed in the state where the rollers are attached to the peripheral surface while feeding to the left. In the correction process path 10g, the left second drive roller pair 152L and the correction roller pair 18 perform ironing processing in which the banknote 3 is straightened in the tangential direction of each roller. That is, when the correction roller pair 18 is provided further downstream of the most downstream drive roller pair to form the correction process path 10g, the warp of the banknote 3 that occurs when passing through the correction process path 10a is corrected. It can be solved by passing 10 g.

If the speed difference between the left second drive roller pair 152L and the correction roller pair 18 is set to be slightly larger than the speed difference between the other roller pairs, the effect of eliminating the warp with respect to the bill 3 can be enhanced. Further, since the leftmost drive roller pair 152L and the correction roller pair 18 which are the most downstream drive roller pair are not arranged in a staggered manner, the separation distance between the left drive roller pair 152L and the correction roller pair 18 becomes long, If the separation distance is sufficiently short with respect to the length of the bill 3 in the conveying direction, the correction function for eliminating the warp of the bill 3 can be exhibited. Further, by disposing two or more correction roller pairs on the downstream side of the most downstream drive roller pair, the correction function for eliminating the warp generated in the banknote 3 can be further enhanced by prolonging the period for performing the ironing process. ..

An example in which the above-described bill correcting device 10″ of the third exemplary embodiment is provided with a correction function for eliminating the warp of the bill 3 by providing the correction roller pair 18 to the bill correcting device 10′ of the second exemplary embodiment. However, the present invention is not limited to this, and for example, by providing the correction roller pair 18 in place of the right second drive roller pair 152R in the bill correcting apparatus 10 of the first embodiment, a correction function for eliminating the warp of the bill 3 is provided. Alternatively, a correction function for eliminating the warp of the bill 3 is added by providing the correction roller pair 18 further downstream of the right second drive roller pair 152R in the bill correcting device 10 of the first embodiment. You may do it.
