Description

This invention relates to a paper sheet processing device.

Conventionally, paper processing devices have been known that have the function of classifying and storing paper materials such as banknotes, securities, and gift certificates according to predetermined types, and the function of counting specific types of paper materials in predetermined quantities. In this type of paper processing device, the temporary holding unit and storage compartment for holding and dispensing paper materials wind the paper materials onto a drum together with tape for holding and dispensing (for example, Patent Document 1).

Japanese Patent Publication No. 2020-149414

However, curled paper sheets held in the temporary holding section or storage compartment may remain on the drum during dispensing, potentially hindering smooth paper dispensing. For example, paper sheets held in the storage compartment for extended periods are prone to curling (warping). When such curled paper sheets are dispensed from the drum, they may become trapped beneath the scraper designed to separate them, potentially preventing normal dispensing.

Therefore, a technical challenge arises in smoothly feeding the paper sheets held in the drum, and the present invention aims to solve this problem.

To achieve the above objective, the paper sheet processing apparatus according to the present invention comprises a winding and storage unit for winding and storing paper sheets together with tape on a drum, and for unwinding the stored paper sheets. The winding and storage unit comprises a scraper for separating the paper sheets stored on the drum from the drum, and a release member integrally provided with the scraper for peeling the unwinded paper sheets from the drum and transferring them to the scraper.

With this configuration, when dispensing the paper sheets that were held wound around the drum along with the tape, the release member separates the paper sheets from the drum as they attempt to follow the drum's rotation, and then the scraper separates the paper sheets from the drum, allowing for smooth dispensing of the paper sheets.

Furthermore, in order to achieve the above objective, the paper sheet processing apparatus according to the present invention comprises a temporary storage unit for temporarily storing paper sheets and a storage unit for transferring the paper sheets between the temporary storage unit and the storage unit. Each unit includes a winding and storage unit for holding the paper sheets by winding them onto a drum along with tape, and for unwinding the held paper sheets. The orientation of the front and back of the paper sheets held by the drum of the temporary storage unit is reversed from the orientation of the paper sheets held by the drum of the storage unit.

With this configuration, each time paper sheets are transferred between the temporary holding area and the storage area, the orientation of the paper sheets (front and back) is reversed when they are held on the drum. This corrects any curling that may have occurred in the paper sheets, preventing them from following the drum and ensuring reliable paper dispensing.

Furthermore, in order to achieve the above objective, the paper sheet processing apparatus according to the present invention comprises a temporary storage unit for temporarily storing paper sheets and a plurality of storage units for transferring the paper sheets between the temporary storage unit and the storage unit. Each storage unit includes a winding and storage unit for holding the paper sheets by winding them onto a drum together with tape and for unwinding the held paper sheets. The orientation of the front and back of the paper sheets held by the drum of one storage unit is reversed from the orientation of the paper sheets held by the drum of the other storage unit.

With this configuration, each time the paper sheets are transferred between multiple storage compartments, the orientation of the paper sheets (front and back) is reversed when they are held in the drum. This corrects any curling that may have occurred in the paper sheets, preventing them from following the drum and ensuring reliable dispensing of banknotes.

This invention allows for smooth dispensing of paper sheets because they are detached from the drum.

<First Embodiment>
The first embodiment of the present invention, the paper sheet processing device 10, processes banknotes as one form of paper sheet, but it is also capable of processing paper sheets other than banknotes. The paper sheet processing device 10 is a banknote deposit and withdrawal device capable of depositing banknotes inserted from the outside and storing them inside, and withdrawaling banknotes stored inside so that they can be taken out to the outside.

As shown in Figure 1, the upper front of the paper sheet processing device 10 is provided with a deposit section 11 into which banknotes for deposit are inserted from the outside. Above and behind this deposit section 11 is a withdrawal section 12 into which rejected banknotes that cannot be accepted are dispensed from the inside, and withdrawal banknotes are dispensed from the inside, allowing them to be removed to the outside.

The deposit section 11 is equipped with a sensor (not shown) for detecting the presence or absence of banknotes, and the withdrawal section 12 is also equipped with a sensor (not shown) for detecting the presence or absence of banknotes. The deposit section 11 and the withdrawal section 12 are positioned so that their heights overlap and their front-to-back positions overlap. Behind the withdrawal section 12 on the top surface of the paper processing device 10, there is a touch-panel type operation display unit 14 (display unit) that receives user input and displays information to the operator, and a calculation unit 15 that controls the entire paper processing device 10. The operation display unit 14 displays the operation screen and information screen regarding the operating status of the paper processing device 10.

Behind the deposit section 11, an identification section 17 for identifying banknotes is provided, with its height overlapping with the deposit section 11. Behind the identification section 17, a temporary holding section 18 for temporarily holding banknotes identified by the identification section 17 is provided, with its height overlapping with both the deposit section 11 and the identification section 17. The lower part of the deposit section 11 and the upper part of the identification section 17 are positioned with their heights overlapping, while the upper part of the deposit section 11 and the lower part of the identification section 17 are positioned with their heights offset. The entire identification section 17 and the middle to lower part of the temporary holding section 18 are positioned with their heights overlapping, while the upper part of the temporary holding section 18 is positioned with its height offset from the identification section 17. The upper part of the temporary holding section 18 is positioned with its height overlapping with the lower part of the dispensing section 12. The deposit section 11, identification section 17, and temporary holding section 18 are arranged in the order of deposit section 11, identification section 17, and temporary holding section 18 from front to rear of the device. The deposit unit 11 and the identification unit 17 are completely offset in the front-to-back direction, and the identification unit 17 and the temporary holding unit 18 are also completely offset in the front-to-back direction.

The deposit section 11 is equipped with a loading plate 19 positioned in a rearward-sloping orientation. This loading plate 19 rises in a rearward-upward direction and descends in a frontward-sloping direction within the deposit section 11. When the loading plate 19 is in its downward-sloping state, the accumulated banknotes are placed on it from the outside, resulting in an upward-sloping arrangement of banknotes. The loading plate 19 then rises, transporting the accumulated banknotes in an upward-sloping direction, and feeding the banknotes one by one into the paper sheet processing device 10, starting from the top of the stack in the accumulation direction.

The paper processing device 10 has an internal transport mechanism 20 for transporting banknotes between a deposit unit 11, a dispensing unit 12, an identification unit 17, a temporary holding unit 18, a forward cassette 51 (described later), and multiple storage compartments 52.

The transport mechanism 20 has a deposit transport path 21 that extends from the rear end of the deposit section 11 and transports the banknotes dispensed from the deposit section 11 to the identification section 17. The deposit transport path 21 has an inclined transport path section 22 that extends downward from the deposit section 11, and a horizontal transport path section 23 that extends horizontally backward from the rear end of the inclined transport path section 22. The deposit transport path 21 is connected to the identification section 17 at the rear end of the horizontal transport path section 23.

The transport mechanism 20 has an internal transport path 25 that is arranged in the same line as the horizontal transport path 23 of the deposit transport path 21 within the identification unit 17 and extends horizontally rearward from the rear end of the horizontal transport path 23. The internal transport path 25 continues to transport banknotes rearward from the horizontal transport path 23. The identification unit 17 identifies the authenticity, correctness, denomination, double feeding, skew, etc., of the banknotes being transported in the internal transport path 25.

The transport mechanism 20 has a straight transport path 26 that extends horizontally backward from the rear end of the internal transport path 25 of the identification unit 17, and the rear end of this straight transport path 26 is connected to the temporary holding unit 18. The straight transport path 26 continues to transport banknotes backward from the internal transport path 25. The horizontal transport path 23 of the deposit transport path 21, the internal transport path 25, and the straight transport path 26 are aligned in a straight line, and the identification unit 17 and the temporary holding unit 18 are connected by the straight transport path 26. For example, banknotes inserted into the deposit unit 11 are transported from the deposit unit 11 towards the identification unit 17 via the deposit transport path 21, and after being identified by the identification unit 17, they are transported to the temporary holding unit 18 via the straight transport path 26. As described above, the identification unit 17 and the temporary holding unit 18 are positioned at the same height, and the straight transport path 26 extends laterally, specifically horizontally, connecting them.

The temporary holding unit 18 holds banknotes, taking in and storing banknotes one by one as they are transported along the linear transport path 26, and then dispensing the stored banknotes one by one back onto the linear transport path 26. The temporary holding unit 18, for example, holds banknotes inserted into the deposit unit 11 and dispenses the stored banknotes. As shown in Figure 2, the temporary holding unit 18 is a winding storage unit that stores banknotes S one by one, along with tape 30, wound onto a drum 31 (rotating body). Therefore, it unwinds the stored banknotes S from the drum 31 along with tape 30 and dispenses them one by one, counting them at intervals. In other words, the temporary holding unit 18 has a drum 31 configured to wind up banknotes S one by one, and the drum 31 dispenses the wound banknotes S one by one.

The temporary holding unit 18 dispenses the banknotes S in the reverse order of their placement. Therefore, even when multiple denominations of banknotes S are randomly mixed and held, the calculation unit 15 can determine the denomination of each banknote S to be held from the identification result of the identification unit 17, and thus can determine the denomination of each banknote S dispensed from the temporary holding unit 18.

The drum 31 of the temporary holding unit 18 is rotatable around a rotation axis, and the tape 30 is wound up when the drum 31 rotates in one direction around the rotation axis (clockwise in Figures 1 and 2). As the tape 30 is wound up, the drum 31 holds the banknotes S one by one between the wound tape 30. The temporary holding unit 18 also discharges the wound tape 30 by rotating the drum 31 in the other direction around the rotation axis (counterclockwise in Figures 1 and 2, corresponding to the dispensing direction D1 described later), thereby dispensing the banknotes S held between the discharged tape 30 one by one. In this embodiment, for example, the maximum number of banknotes S that can be held in the temporary holding unit 18 is 600.

The structure of the temporary holding section 18 will now be described in detail. As shown in Figures 3 and 4, a scraper 32 and a first peeling member 33 are provided near the drum 31, which holds and dispenses the banknotes S. Reference numeral 30a indicates a reel for dispensing the tape 30, and reference numeral 34 indicates a regulating roller that restricts the trajectory of the tape 30.

The scraper 32 is positioned downstream of the free space FS where the tape 30 separates from the drum 31 in the dispensing direction D1 when viewed from the side, for dispensing banknotes S. The scraper 32 is provided at positions corresponding to the two tapes 30. The two scrapers 32 are connected via a support shaft 32a.

The scraper 32 is pivotable around the support shaft 32a according to the number of banknotes S stored, and the tip 32b of the scraper 32 is located near the banknotes S stored on the outermost circumference of the drum 31, regardless of the amount of banknotes S stored. The banknotes S, which were wound onto the drum 31 together with the tape 30, are peeled off the drum 31 by riding up on the tip 32b when the drum 31 rotates in the unwinding direction D1 and the winding by the tape 30 is released. They are then transported through the space between the tape 30 and the scraper 32 to the rear transport path 26b, which will be described later.

The first release member 33 is equipped with an impeller 331. The impeller 331 is made of an elastic material, such as rubber. Viewed from the side, the impeller 331 has five blades 331b extending radially from the base 331a and spaced approximately equally apart. The tips of the front surfaces 331c of the blades 331b are extended to the extent that they can contact the tape 30 or the banknotes S held in the drum 31. The blades 331b are flexible and elastically deform when they come into contact with the tape 30, etc.

As shown in Figure 5, the impeller 331 is provided one on the outside of each of the two tip portions 32b on the scraper 32. The base portion 331a is connected to the rotating shaft 331d, which is supported by the tip portions 32b. The rotating shaft 31a of the drum 31 and the rotating shaft 331d of the impeller 331 are arranged approximately parallel to each other.

As shown in Figures 6 and 7, the rotating shaft 331d passes through a support plate 333 that pivotally supports the rotating shaft 332a of the intermediate roller 332. That is, the intermediate roller 332 is configured to revolve around the rotating shaft 331d. The intermediate roller 332 is in contact with the outer circumferential surface of the drum 31 or with the banknotes S stored on the outermost periphery of the drum 31, and rotates in the opposite direction to the drum 31 in accordance with the rotation of the drum 31. In addition, the intermediate roller 332 is in contact with the outer circumferential surface of the driven roller 331e, which is integrated with the rotating shaft 331d, and rotates the driven roller 331e in the opposite direction to the intermediate roller 332. In this way, the drum 31 and the impeller 331 are configured to rotate in the same direction when viewed from the side. Reference numeral 331f indicates a torsion spring, which is a biasing member that biases the intermediate roller 332 so that it is always in contact with the banknotes S stored on the outermost periphery of the drum 31, regardless of the amount of banknotes S stored in the drum 31. Alternatively, instead of the intermediate roller 332 that transmits the driving force of the drum 31 to rotate the impeller 331, a motor (not shown) capable of driving the rotating shaft 331d may be provided.

Furthermore, in order to support the banknotes S wound on the drum 31, support rollers (not shown) that contact the tape 30 wound on the drum 31 may be provided.

As shown in Figure 1, the transport mechanism 20 has a dispensing transport path 37 that branches upward from an intermediate position in the straight transport path 26, and this dispensing transport path 37 is connected to the dispensing section 12. The branching of the dispensing transport path 37 divides the straight transport path 26 into a front transport path section 26a on the front side of the branching point of the dispensing transport path 37, and a rear transport path section 26b on the rear side of the branching point of the dispensing transport path 37. Banknotes S can move back and forth between the front transport path section 26a and the rear transport path section 26b. Between the front transport path section 26a and the dispensing transport path 37, banknotes S can be transported from the front transport path section 26a to the dispensing transport path 37, and between the rear transport path section 26b and the dispensing transport path 37, banknotes S can be transported from the rear transport path section 26b to the dispensing transport path 37.

The dispensing transport path 37 transports banknotes S, which have been transported on the straight transport path 26, to the dispensing section 12. It comprises a lead direct transport section 37a extending vertically upward from the middle of the straight transport path 26, a horizontal transport section 37b extending horizontally forward from the upper end of the lead direct transport section 37a, a lead direct transport section 37c extending vertically upward from the front end of the horizontal transport section 37b, and a horizontal transport section 37d extending horizontally forward from the upper end of the lead direct transport section 37c and connecting to the dispensing section 12.

Here, the dispensing unit 12 diagonally accumulates the banknotes S dispensed from the horizontal transport section 37d of the dispensing transport path 37, from the front and bottom to the rear and top. The banknotes S accumulated in the dispensing unit 12 are then removed to the outside. The dispensing transport path 37, for example, dispenses banknotes S from the temporary holding section 18 into the straight transport path 26, then branches off upwards from the middle of the straight transport path 26 and transports them to the dispensing unit 12.

The deposit unit 11, withdrawal unit 12, operation display unit 14, identification unit 17 including the internal transport path 25, temporary holding unit 18, deposit transport path 21, straight transport path 26, and withdrawal transport path 37 are provided in the upper unit 41, which constitutes the upper part of the paper sheet processing device 10.

The lower unit 42, located below the upper unit 41 and forming the middle to lower part of the paper sheet processing device 10 in the height direction, has a front cassette 51 at its front position. Behind the front cassette 51, there are a total of eight storage compartments 52 arranged in two upper and lower tiers and four front and rear rows. Of the eight storage compartments 52, the four compartments in the upper tier are aligned in the height direction, and the four compartments in the lower tier are also aligned in the height direction. The height of the front cassette 51 is equivalent to the height of two storage compartments 52, and the front cassette 51 is aligned in the height direction with the two upper and lower tiers of storage compartments 52.

The conveying mechanism 20 has an upper and lower conveying path 55 that branches downward from an intermediate position in the horizontal conveying path section 23 of the deposit conveying path 21. This upper and lower conveying path 55 extends vertically downward from the horizontal conveying path section 23 and is connected to the front cassette 51. The branching of the upper and lower conveying path 55 divides the horizontal conveying path section 23 of the deposit conveying path 21 into a front component 23a located in front of the branching point of the upper and lower conveying path 55, and a rear component 23b located behind the branching point of the upper and lower conveying path 55. Between the front component 23a and the rear component 23b, it is possible to convey banknotes S from the front component 23a to the rear component 23b, and between the upper and lower conveying path 55 and the rear component 23b, it is possible to move banknotes S back and forth. The upper and lower transport paths 55, for example, feed banknotes S from the temporary holding section 18 onto the straight transport path 26 and, after passing through the identification section 17, branch off downwards from the middle of the deposit transport path 21 on the opposite side of the straight transport path 26 of the identification section 17 to store them in the front cassette 51.

The front cassette 51 is capable of receiving and storing banknotes S one at a time, and can dispense the stored banknotes S one at a time. The front cassette 51 is a stacking storage unit that receives banknotes S from the top, stacks them horizontally from bottom to top, and dispenses the stored banknotes S from the top end. The front cassette 51 has significantly higher banknote storage efficiency compared to winding storage units such as the temporary holding unit 18 and the storage compartment 52 described later. On the other hand, winding storage units such as the temporary holding unit 18 and the storage compartment 52 described later have a lower possibility of double feeding of banknotes S compared to the stacking storage unit front cassette 51, and can accurately separate and dispense the held banknotes S one by one with appropriate spacing.

The transport mechanism 20 has a storage transport path 57 that branches off to the rear from an intermediate position in the upper and lower transport paths 55. This storage transport path 57 extends horizontally rearward from the upper and lower transport paths 55, then extends downward near the rear end of the paper sheet processing device 10, connecting to the upper rear storage compartment 52. This storage compartment 52 also connects to the lower rear storage compartment 52. The branching of the storage transport path 57 divides the upper and lower transport paths 55 into an upper transport path section 55a above the branching point of the storage transport path 57, and a lower transport path section 55b below the branching point of the storage transport path 57.

The transport mechanism 20 has multiple branch transport paths 61, 62, and 63 that branch downward from an intermediate position in the storage transport path 57. The branch transport paths 61, 62, and 63 are connected to the upper storage compartments 52 of the front three rows, and via each of the upper storage compartments 52, they are connected to the lower storage compartments 52 of the same row.

The eight storage units 52 are all winding storage units that store banknotes S one by one, with intervals between them, wound onto a drum 71 along with a tape 70 (described later). Therefore, the stored banknotes S are unwound from the drum 71 along with the tape 70 and dispensed one by one, counted at intervals. The storage units 52 dispense the banknotes S in the reverse order of their storage. For this reason, even when multiple denominations of banknotes S are randomly mixed and stored in one unit, the calculation unit 15 can determine the denomination of each banknote S stored from the identification result of the identification unit 17, and thus can determine the denomination of each banknote S dispensed from the storage unit 52.

The structure of the storage compartment 52 will now be described in detail. As shown in Figures 8 and 9, a scraper 72 and a second peeling member 73 are arranged near the drum 71, which holds and dispenses banknotes S. Reference numeral 70a indicates a reel for dispensing the tape 70, and reference numeral 74 indicates a regulating roller that restricts the trajectory of the tape 70.

The scraper 72 is positioned downstream of the free space FS where the tape 70 separates from the drum 71 in the dispensing direction D2 when viewed from the side, which is the direction in which the banknotes S are dispensed. The scraper 72 is provided at positions corresponding to the two tapes 70. The two scrapers 72 are connected via a support shaft 72a.

The scraper 72 is pivotable around the support shaft 72a according to the number of banknotes S stored, and the tip 72b of the scraper 72 is located near the banknotes S stored on the outermost circumference of the drum 71, regardless of the amount of banknotes S stored. The banknotes S, which were wound onto the drum 71 together with the tape 70, are peeled off the drum 71 by riding over the tip 72b when the drum 71 rotates in the unwinding direction D2 and the winding by the tape 70 is released. They are then transported through the tape 70 and the scraper 72 to the branch transport paths 61-63 or the storage transport path 57.

The second release member 73 has the same configuration as the first release member 33 described above. That is, the second release member 73 includes an impeller 731. The impeller 731 is made of an elastic material such as rubber. Viewed from the side, the impeller 731 has five blades 731b extending radially from the base 731a and arranged at approximately equal intervals. The tips of the front surfaces 731c of the blades 731b are extended to the extent that they can contact the tape 70 or the banknotes S held in the drum 71. The blades 731b are flexible and elastically deform when they come into contact with the tape 70, etc.

The impellers 731 are provided one at a time on the outside of the tip portion 72b. The base portion 731a is connected to the rotating shaft 731d, which is supported by the tip portion 72b. The rotating shaft 71a of the drum 71 and the rotating shaft 731d of the impellers 731 are positioned approximately parallel to each other.

The rotating shaft 731d passes through a support plate 733 that pivotally supports the rotating shaft 732a of the intermediate roller 732. That is, the intermediate roller 732 is configured to revolve around the rotating shaft 731d. The intermediate roller 732 is capable of contacting the outer circumferential surface of the drum 71 or the banknotes S contained on the outermost periphery of the drum 71, and rotates in the opposite direction to the drum 71 in accordance with the rotation of the drum 71. The intermediate roller 732 is also capable of contacting the outer circumferential surface of the driven roller 731e, which is integrated with the rotating shaft 731d, and rotates the driven roller 731e in the opposite direction to the intermediate roller 732. In this way, the drum 71 and the impeller 731 are configured to rotate in the same direction when viewed from the side. The intermediate roller 732 is biased by a torsion spring (not shown) to always be in contact with the banknotes S contained on the outermost periphery of the drum 71, regardless of the amount of banknotes S contained in the drum 71. Alternatively, instead of the intermediate roller 732 that transmits the driving force of the drum 71 to rotate the impeller 731, a motor (not shown) capable of driving the rotating shaft 731d may be provided.

Furthermore, in order to support the banknotes S wound on the drum 71, support rollers (not shown) that contact the tape 70 wound on the drum 71 may be provided.

The storage transport path 57 and branch transport paths 61, 62, and 63 selectively store banknotes S, which have been fed from the temporary holding section 18 to the straight transport path 26 and passed through the identification section 17, by branching downwards from the middle of the deposit transport path 21 and branching backwards from the middle of the upper and lower transport path 55, into eight storage units 52. The eight storage units 52 can be configured, for example, as single-denomination storage units, each storing only banknotes of a single denomination; or as some of them, each storing only banknotes of a single denomination, and the rest as mixed-denomination storage units, each storing banknotes of multiple denominations in a mixed-denomination configuration.

The lower unit 42 is equipped with a front cassette 51, eight storage compartments 52, the lower part of the upper transport section 55a of the vertical transport path 55, the lower transport section 55b, a storage transport path 57, and branch transport paths 61-63. The upper part of the upper transport section 55a of the vertical transport path 55 is provided in the upper unit 41.

The lower unit 42 comprises a rectangular box-shaped housing 77 that opens to the front, a unit body 78 containing eight storage compartments 52 arranged inside the housing 77, and a door body 79 that opens and closes the front opening of the housing 77. The front cassette 51 is detachably attached to the unit body 78.

As shown in Figure 2, the calculation unit 15 includes a control unit 81 that controls the drive of the deposit unit 11, temporary holding unit 18, transport mechanism 20, front cassette 51, and multiple storage compartments 52 of the paper sheet processing device 10 as shown in Figure 1; a calculation unit 82 that calculates the number of banknotes S that can be held in the temporary holding unit 18; a display information generation unit 83 that generates display information to be displayed on the operation display unit 14; and a mode switching unit 84 that switches the operating mode of the paper sheet processing device 10 according to the operation input to the operation display unit 14.

The control unit 81 performs, for example, control of the dispensing of banknotes S in the deposit unit 11, control of the dispensing of banknotes S in the temporary holding unit 18, control of the transport mechanism 20 for banknotes S inserted into and dispensed from the deposit unit 11, and control of the transport mechanism 20 for banknotes S dispensed from the temporary holding unit 18. The control unit 81 also performs, for example, control of batch processing, such as dispensing banknotes S held in the temporary holding unit 18 in batches and dispensing them in the dispensing unit 12. In batch processing, the control unit 81 reserves the maximum number of banknotes S that can be held in the temporary holding unit 18, calculated by the calculation unit 82, from the banknotes S inserted into the deposit unit 11.

Next, the main operation of the paper sheet processing device 10 according to this embodiment will be described.

The mode switching unit 84 of the calculation unit 15 switches the operating mode of the paper sheet processing device 10 in response to the operation input to the operation display unit 14. In this embodiment, the device switches between a storage mode in which multiple banknotes S inserted into the deposit unit 11 are sorted by denomination and stored in storage compartments 52 designated for each denomination; a withdrawal mode in which banknotes S are withdrawn from the multiple storage compartments 52 to the withdrawal unit 12 for easy withdrawal; and a counting mode in which banknotes S of the same specific denomination are counted in preset batch numbers from multiple banknotes S inserted into the deposit unit 11, divided into batches of that number, and withdrawn to the withdrawal unit 12.

In other words, the mode switching unit 84 switches the paper sheet processing device 10 between three operating modes: a counting mode in which a predetermined batch number of banknotes S from multiple banknotes S inserted into the deposit unit 11 are counted and transported to the dispensing unit 12 as needed; a storage mode in which multiple banknotes S inserted into the deposit unit 11 are sorted and stored according to predetermined types; and a dispensing mode in which banknotes S of a specified type are dispensed to the dispensing unit 12 for easy dispensing. The paper sheet processing device 10 is switched between storage mode, dispensing mode, and counting mode by the mode switching unit 84 in response to an operator's operation on the operation display unit 14. Note that the operating modes of the paper sheet processing device 10 are not limited to these three modes, and it may have other operating modes.

When the mode switching unit 84 switches the paper sheet processing device 10 to storage mode in response to an operation input to the operation display unit 14, the control unit 81 performs the following deposit and storage processing, or deposit and return processing, in response to the operation input to the operation display unit 14.

[Payment Processing]
When a sensor (not shown) detects that banknotes S have been inserted into the deposit section 11 from an external source, and an operation to start the deposit process is input to the operation display unit 14, the paper sheet processing device 10 is controlled by the control unit 81, and the deposit section 11 and transport mechanism 20 transport the banknotes S along the deposit processing route shown by the thick line in Figure 10.

In other words, the deposit unit 11 separates the banknotes S one by one and dispenses them at predetermined intervals. The dispensed banknotes S are then transported by the deposit transport path 21 of the transport mechanism 20, the internal transport path 25 of the identification unit 17, and the front transport path 26a of the straight transport path 26. While the banknotes are being transported in the internal transport path 25, the identification unit 17 identifies the banknotes S. Banknotes S identified as acceptable by the identification unit 17 are transported from the front transport path 26a of the straight transport path 26 to the rear transport path 26b, where the rear transport path 26b transports them to the temporary holding unit 18, where the temporary holding unit 18 holds them (see the thick solid line in Figure 10). On the other hand, banknotes S identified as unacceptable by the identification unit 17 are transported from the front transport path 26a of the straight transport path 26 to the withdrawal transport path 37, where the withdrawal transport path 37 transports them to the withdrawal unit 12 (see the thick solid to thick dashed line in Figure 10).

Here, since the deposit unit 11 separates and dispenses banknotes S that are stacked in the thickness direction, there is a possibility of transport defects such as double feeding or skewed banknotes S occurring during dispensing. The identification unit 17 identifies such defective banknotes S as unacceptable, and the transport mechanism 20 transports them to the dispensing unit 12. Furthermore, if banknotes S to be transported to the dispensing unit 12 arise during the deposit process, the control unit 81 stops the temporary holding unit 18 accordingly and controls the interval between the banknotes S held in the temporary holding unit 18 and the banknotes S being taken in to maintain a constant interval.

When all the banknotes S inserted into the deposit section 11 have been transported to either the temporary holding section 18 or the dispensing section 12, the operation display section 14 displays the number of banknotes of each denomination and the total amount of banknotes S temporarily stored in the temporary holding section 18, based on the identification result from the identification section 17. Banknotes S transported to the dispensing section 12 become available for external removal. Alternatively, a separate reject section may be provided to allow banknotes S to be removed externally, and unacceptable banknotes S may be transported to this reject section.

[Storage Processing]
After the amount information is displayed on the operation display unit 14 following the deposit processing, when the operator inputs an approval operation to the operation display unit 14, the paper sheet processing device 10 is controlled by the control unit 81 and transports the banknotes S along the storage processing route shown by the thick line in Figure 11 using its temporary holding unit 18, transport mechanism 20, and eight storage units 52.

In other words, the temporary holding unit 18 dispenses the temporarily stored banknotes S one by one at intervals, and these are transported by the straight transport path 26, the internal transport path 25 of the identification unit 17, the rear component 23b of the deposit transport path 21, the upper transport path 55a of the upper and lower transport path 55, and the storage transport path 57. While the banknotes are being transported in the internal transport path 25, the identification unit 17 identifies the banknotes S. Based on this identification, the storage transport path 57 and the branch transport paths 61-63 sort the banknotes S into their corresponding storage units 52. The sorted banknotes S are then stored in their corresponding storage units 52.

Here, since the temporary holding unit 18 is a winding storage unit, it rarely causes transport defects such as double feeding or skewed banknotes S during dispensing, and it is unlikely that any banknotes S dispensed by the temporary holding unit 18 will be deemed unstorable by the identification unit 17. However, banknotes S that experience transport defects during dispensing from the temporary holding unit 18 may be transported, for example, to a storage unit 52 configured to accumulate rejected banknotes.

Incidentally, when a curved banknote S is fed from the drum 31, there is a risk that the banknote S may enter the space between the tip 32b of the scraper 32 and the drum 31 without riding up onto the tip 32b. However, the impeller 331 separates the banknote S from the drum 31, ensuring that the banknote S is fed out reliably.

Specifically, as shown in Figure 12(a), the drum 31 and the impeller 331 rotate in the same direction when viewed from the side. The tip of the blade portion 331b that contacts the drum 31 elastically deforms along the feeding direction D1 in the free space FS so that it follows the outermost circumference of the drum 31.

Next, as shown in Figure 12(b), when the banknote S begins to be fed out of the drum 31, the leading edge of the banknote S reaches the free space FS, and the clamping between the tape 30 and the drum 31 is released. Then, the elastically deformed wing portion 331b downstream of the free space FS strikes the leading edge of the banknote S.

As more banknotes S are dispensed, as shown in Figure 12(c), the tip of the blade portion 331b flips up the banknotes S in a convex shape due to friction, separating them from the drum 31.

Then, as more banknotes S are dispensed, as shown in Figure 12(d), the blade portion 331b presses the banknotes S against the tape 30 and transfers them. Afterward, the entire banknote S is dispensed from the drum 31, riding over the tip portion 32b of the scraper 32, and is transported to the rear feed path 26b via the space between the tape 30 and the scraper 32. Note that in Figure 12, intermediate rollers 322 and other components are omitted for clarity in illustrating the behavior of the impeller 321.

[Return Processing]
After the operation display unit 14 displays the amount information following the deposit processing, when the operator inputs a return operation to the operation display unit 14, the paper sheet processing device 10 is controlled by the control unit 81 and, using its temporary holding unit 18, transport mechanism 20, and dispensing unit 12, transports the banknotes S along the return processing route shown by the thick line in Figure 13.

In other words, the temporary holding unit 18 dispenses the temporarily stored banknotes S one by one at intervals, and the rear transport section 26b of the linear transport path 26 and the dispensing transport path 37 transport them to the dispensing unit 12. The banknotes S transported to the dispensing unit 12 become available for external removal.

Here, the banknotes S dispensed from the temporary holding section 18 are separated from the drum 31 by the impeller 331, as shown in Figures 12(a) to (d), and then dispensed from the drum 31 by riding onto the tip 32b of the scraper 32, and transported to the rear transport section 26b.

When the mode switching unit 84 switches the paper sheet processing device 10 to the dispensing mode in response to an operation input to the operation display unit 14, the control unit 81 performs the following dispensing process in response to the operation input to the operation display unit 14.

[Withdrawal Processing]
When the amount information of the banknotes S to be withdrawn, along with the selection operation for the withdrawal process, is entered into the operation display unit 14, if banknotes S are to be withdrawn from a storage unit 52 set as a single-denomination storage unit, the paper sheet processing device 10 is controlled by the control unit 81 and transports the banknotes S from the storage unit 52 containing the banknotes S of the withdrawal target denomination via the transport mechanism 20 and the withdrawal unit 12 along the withdrawal process route shown by the thick line in Figure 14.

In other words, the corresponding storage unit 52 separates and counts the stored banknotes S one by one, dispensing them at intervals. The dispensed banknotes S are then transported to the dispensing unit 12 via the appropriate branch transport paths 61-63, the storage transport path 57, the upper transport path section 55a of the upper and lower transport path 55, the rear component section 23b of the deposit transport path 21, the internal transport path 25 of the identification unit 17, the front transport path section 26a of the straight transport path 26, and the dispensing transport path 37. Here, since all storage units 52 are winding storage units, transport defects such as double feeding and skewed banknotes S rarely occur during dispensing, and it is unlikely that any banknotes S dispensed by the storage unit 52 will be judged as unusable by the identification unit 17. However, banknotes S that experience transport defects during dispensing from the storage unit 52 may be transported to, for example, a storage unit 52 configured to accumulate rejected tickets. The banknotes S transported to the dispensing unit 12 can be removed externally.

Incidentally, when a curved banknote S is fed out of the drum 71, there is a risk that the banknote S may enter the space between the tip 72b of the scraper 72 and the drum 71 without riding up onto the tip 72b of the scraper 72. However, the impeller 731 separates the banknote S from the drum 71, ensuring reliable transport of the banknote S.

Specifically, as shown in Figures 12(a) to (d), similar to the case where the impeller 331 separates the banknote S from the drum 31, first, in the free space FS, the tip of the blade portion 731b that contacts the drum 71 is elastically deformed along the feeding direction D2 so as to follow the outermost circumference of the drum 71. When the banknote S begins to be fed out of the drum 71, the tip of the banknote S reaches the free space FS and the clamping between the tape 70 and the drum 71 is released. Then, the elastically deformed blade portion 731b downstream of the free space FS strikes the tip of the banknote S. As the banknote S is fed out further, the tip of the blade portion 731b peels up the banknote S by friction and separates it from the drum 71. Then, as the banknote S is fed out further, the blade portion 731b presses the banknote S against the tape 70 and transfers it. Subsequently, the entire banknote S is fed out of the drum 71, riding over the tip 72b of the scraper 72, and transported through the tape 70 and the scraper 72 to the branch transport paths 61-63 or the storage transport path 57.

Thus, the paper sheet processing apparatus 10 according to this embodiment includes a temporary holding unit 18 for holding banknotes S together with the tape 30 on a drum 31 and for dispensing the held banknotes S. The temporary holding unit 18 is configured to include a scraper 32 for separating the banknotes S contained in the drum 31 from the drum 31, and a first peeling member 33 provided integrally with the scraper 32 for peeling the banknotes S dispensed from the drum 31 and handing them over to the scraper 32.

With this configuration, when dispensing the banknotes S that were held in place wound around the drum 31 along with the tape 30, the first release member 33 separates the banknotes S from the drum 31 as they attempt to follow the rotation of the drum 31. Then, the banknotes S are separated from the drum 31 by the scraper 32, allowing for smooth dispensing of the banknotes S.

Furthermore, in the paper sheet processing apparatus 10 according to this embodiment, the first release member 33 comprises a base portion 331a connected to a rotating shaft 331d that is rotatable in the same direction as the drum 31, and a plurality of blade portions 331b extending radially from the base portion 331a. The blade portions 331b are configured to peel up the banknotes S contained in the drum 31, thereby separating the banknotes S from the drum 31.

With this configuration, the blade portion 331b peels away the banknotes S as they try to follow the rotation of the drum 31, allowing the banknotes S to be dispensed smoothly.

Furthermore, the paper sheet processing apparatus 10 according to this embodiment includes a storage compartment 52 for holding banknotes S together with tape 70 on a drum 71 and for dispensing the held banknotes S. The storage compartment 52 comprises a scraper 72 for separating the banknotes S contained in the drum 71 from the drum 71, and a second peeling member 73 integrally provided with the scraper 72 for peeling the banknotes S dispensed from the drum 71 and transferring them to the scraper 72.

With this configuration, when dispensing the banknotes S that were held in place wound around the drum 71 along with the tape 70, the second release member 73 separates the banknotes S from the drum 71 as they attempt to follow the rotation of the drum 71. Then, the banknotes S are separated from the drum 71 by the scraper 72, allowing for smooth dispensing of the banknotes S.

Furthermore, in the paper sheet processing apparatus 10 according to this embodiment, the second release member 73 comprises a base portion 731a connected to a rotating shaft 731d that is rotatable in the same direction as the drum 71, and a plurality of blade portions 731b extending radially from the base portion 731a. The blade portions 731b are configured to peel the banknotes S contained in the drum 71 upwards, thereby separating the banknotes S from the drum 71.

With this configuration, the blade portion 731b peels away the banknotes S as they try to follow the rotation of the drum 71, allowing the banknotes S to be dispensed smoothly.

Next, various modifications of this embodiment will be described. While the following examples illustrate various configurations of the temporary holding section 18, the same principles apply to the various configurations of the storage compartment 52.
<Variation 1>
In the embodiment described above, a configuration in which one impeller 331 is arranged on each side of the tip portion 32b of the scraper 32 was illustrated. However, as shown in Figures 15, 16, and 17, the impeller 331 may be arranged in the center of the tip portion 32b.

Specifically, the two impellers 331 are positioned in the center of the U-shaped tip portion 32b when viewed from above. The base portion 331a of the impellers 331 is connected to a rotating shaft 331d, which is pivotally supported by the tip portion 32b. As a result, the tip portion 32b and the impellers 331 are positioned to overlap when viewed from above, allowing the banknotes S, separated from the drum 31 by the impellers 331, to be smoothly transferred to the scraper 32.

<Modified Example 2>
In the embodiment described above, an impeller 331 with a substantially flat front surface 331c was illustrated. However, as shown in Figures 18(a) and (b), a U-shaped groove 331g may be provided on the front surface 331c, extending in the width direction, on the tip side that can contact the banknote S. This ensures that when the blade portion 331b flips up the banknote S, the corner of the groove 331g catches on the banknote S, thereby reliably separating the banknote S from the drum 31.

The position of the groove 331g can be adjusted according to the area of the front surface 331c that contacts the banknote S. For example, as shown in Figures 19(a) and (b), a flat portion 331h may be formed at the tip of the front surface 331c, and the groove 331g may be formed from the middle of the front surface 331c, which is the base end of the flat portion 331h, to the vicinity of the base portion 331a. Furthermore, the cross-sectional shape of the groove 331g is not limited to a U-shape and can be any shape.

Alternatively, instead of the groove 331g, a ridge-like bump 331i may be provided on the front surface 331c, extending in the width direction, on the tip side that can contact the banknote S, as shown in Figures 20(a) and (b). This ensures that when the wing portion 331b flips up the banknote S, the bump 331i catches on the banknote S, thereby reliably separating the banknote S from the drum 31. The position of the bump 331i can be adjusted according to the position where the banknote S is caught; it may be located on the tip side of the front surface 331c as shown, or, for example, in the middle of the front surface 331c. Furthermore, the cross-sectional shape of the bump 331i is not limited to a semicircular shape and can be any shape.

<Example 3>
In the embodiment described above, a first peeling member 33 was exemplified, in which the impeller 331 flips up the banknote S so as to separate it from the drum 31. However, the peeling member that separates the banknote S from the drum 31 in the free space FS is not limited to this.

For example, as shown in Figure 21, an electrostatic chuck 334 is positioned on the opposite side of the drum 31 via the tape 30. The electrostatic chuck 334 uses electrical force to firmly attach the banknote S to the tape 30, thereby allowing the banknote S to be detached from the drum 31.

Furthermore, as shown in Figure 22, for example, a vacuum chuck 335 can be positioned on the opposite side of the drum 31 via the tape 30. The vacuum chuck 335 uses negative pressure supplied from the vacuum pump 335a to tightly adhere the banknote S to the tape 30, thereby separating the banknote S from the drum 31.

Furthermore, as shown in Figure 23, for example, an air nozzle 336 is positioned near the free space FS to discharge air from the drum 31 towards the tape 30. The air nozzle 336 discharges air supplied from the air pump 336a, pressing the banknote S against the tape 30, thereby separating the banknote S from the drum 31.

<Second Embodiment>
Next, a paper sheet processing apparatus 10 according to the second embodiment of the present invention will be described with reference to Figure 24. Note that, except for the configuration described below, the paper sheet processing apparatus 10 according to this embodiment has the same configuration as the paper sheet processing apparatus 10 according to the first embodiment described above, so redundant explanations will be omitted.

The drum 31 of the temporary holding section 18 is set to have a dispensing direction D1, which is the direction of rotation when dispensing banknotes S, set to counterclockwise in Figure 24. On the other hand, the drum 71 of the upper storage compartment 52A, one of the two storage compartments 52, is set to have a dispensing direction D2A, which is the direction of rotation when dispensing banknotes S, set to counterclockwise in Figure 24. In other words, the orientation of the front and back of the banknotes S held by the drum 31 of the temporary holding section 18 and the orientation of the banknotes S held by the drum 71 of the storage compartment 52 are reversed.

This allows, for example, banknotes S stored in the upper storage compartment 52A with one side facing the drum 71 for an extended period of time to develop a curl. However, when the banknotes S are transferred to the temporary holding section 18 via the branching transport path 61, storage transport path 57, upper/lower transport path 55, and straight transport path 26, the banknotes S are stored in the temporary holding section 18 with the other side facing the drum 31. This corrects the curl that has developed in the banknotes S.

Furthermore, banknotes S, which tend to have a large curvature and a strong curl when stored at the innermost circumference of drum 71, are transferred to drum 31 and stored at the outermost circumference of drum 31, resulting in a smaller curvature and a gentler curl in the opposite direction. Therefore, the transfer of banknotes S between the temporary holding section 18 and the storage compartment 52 alleviates the curl of the banknotes S.

Furthermore, in the two-tiered storage compartment 52, the drum 71 of the upper compartment 52A is set to have a dispensing direction D2A, which is the direction of rotation when dispensing banknotes S, set to counterclockwise in Figure 24. In contrast, the drum 71 of the lower compartment 52B is set to have a dispensing direction D2B, which is the direction of rotation when dispensing banknotes S, set to clockwise in Figure 24. That is, the orientation of the front and back of the banknotes S held by the drum 71 of the upper compartment 52A is reversed compared to the orientation of the banknotes S held by the drum 71 of the lower compartment 52B.

As a result, even if banknotes S develop a curl after being stored in the upper storage compartment 52 with one side facing the drum 71 for an extended period, the banknotes S are transferred to the temporary holding section 18 via the branching transport path 61, storage transport path 57, upper/lower transport path 55, and straight transport path 26. Then, after being transferred to the lower storage compartment 52 via the straight transport path 26, upper/lower transport path 55, storage transport path 57, and branching transport path 61, the banknotes S are stored in the lower storage compartment 52 with the other side facing the drum 71. This corrects the curl that has developed in the banknotes S.

Thus, the paper sheet processing apparatus 10 according to this embodiment includes a temporary holding section 18 for temporarily storing banknotes S, a storage unit 52 for transferring banknotes S between the temporary holding section 18 and the storage unit 52, and a winding storage unit for holding banknotes S by winding them onto drums 31 and 71 together with tapes 30 and 70, and for dispensing the held banknotes S. The configuration is such that the front and back orientation of the banknotes S held by drum 31 of the temporary holding section 18 and the front and back orientation of the banknotes S held by drum 71 of the storage unit 52 are reversed.

With this configuration, each time a banknote S is transferred between the temporary holding section 18 and the storage compartment 52, the orientation of the banknote S (front and back) is reversed when it is held in the drums 31 and 71. This corrects any curling that may have occurred in the banknote S, thereby preventing the banknote S from following the drums 31 and 71 and ensuring reliable dispensing of the banknote S.

Furthermore, the paper sheet processing device 10 according to this embodiment includes a temporary holding section 18 for temporarily storing banknotes S, and a plurality of storage compartments 52 for transferring banknotes S between the temporary holding section 18. Each compartment also includes a winding storage unit that winds banknotes S together with tapes 30 and 70 onto drums 31 and 71 for storage, and a winding storage unit for dispensing the stored banknotes S. The configuration is such that the orientation of the banknotes S held by the drum 71 of one storage compartment 52 is reversed from the orientation of the banknotes S held by the drum 71 of the other storage compartment 52.

With this configuration, each time banknotes S are transferred between multiple storage compartments 52, the orientation of the banknotes S when they are held in the drum 71 is reversed. This corrects any curling that may have occurred in the banknotes S, preventing them from following the drum 71 and ensuring reliable dispensing of the banknotes S.

Furthermore, the present invention can be modified in various ways beyond those described above, as long as it does not deviate from the spirit of the invention, and it goes without saying that the present invention extends to such modified versions.

For example, while we have described a paper sheet processing device 10 that processes banknotes as paper sheets, this method can also be applied to devices that process various other types of paper sheets, such as securities or monetary instruments.

Furthermore, the embodiments and variations described above may be combined as appropriate.
