Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the warped paper sheets stored in the temporary storage unit or the storage bin may remain on the drum without separating from the drum during feeding, and there is a risk that the paper sheets cannot be fed out smoothly. For example, the paper sheets stored in the storage bin for a long time are likely to develop a curl (warp). And when such warped paper sheets are fed out from the drum, the paper sheets may get under the scraper provided to lift the paper sheets and separate them from the drum, and there is a risk that the feeding cannot be performed normally.

[0005] Therefore, a technical problem to be solved arises in order to smoothly feed out the paper sheets stored on the drum, and an object of the present invention is to solve this problem.

Means for Solving the Problems

[0006] In order to achieve the above object, a sheet processing apparatus according to the present invention includes a winding storage unit that winds and stores sheets together with a tape on a drum, and feeds out the stored sheets. The winding storage unit includes a pressing member that presses the sheets accommodated in the drum toward the drum to correct the warp of the sheets, and a scraper that peels off the warped-corrected sheets fed out from the drum from the drum.

[0007] According to this configuration, prior to feeding out the sheets that were wound and stored on the drum together with the tape, the pressing member corrects the warp of the sheets, so that the sheets are steadily peeled off from the drum by the scraper, and thus the sheets can be fed out smoothly.

Advantages of the Invention

[0008] In the present invention, since the sheets are peeled off from the drum in a state where the warp is corrected by the pressing member, the sheets can be fed out smoothly.

[0012] Also, the drawings may be exaggerated, such as enlarging characteristic parts for easy understanding of the characteristics, and the dimensional ratios of components are not necessarily the same as the actual ones.

[0013] The banknote processing device 10 according to this embodiment processes banknotes as one type of paper sheets, but can also process paper sheets other than banknotes. The banknote processing device 10 is a banknote depositing and withdrawing device capable of performing a depositing process of storing banknotes input from the outside inside and a withdrawing process of withdrawing the banknotes stored inside to the outside in a retrievable manner.

[0014] As shown in FIG. 1, at the upper part of the front side of the banknote processing device 10, a depositing unit 11 into which depositing banknotes are input from the outside is provided. Above and behind this depositing unit 11, a reject banknote that cannot be accepted among the depositing banknotes is fed out from the inside, and a withdrawing unit 12 for feeding out withdrawing banknotes from the inside and making them retrievable to the outside is provided.

[0015] The depositing unit 11 is provided with a sensor (not shown) for detecting the presence or absence of banknotes in the depositing unit 11, and the withdrawing unit 12 is also provided with a sensor (not shown) for detecting the presence or absence of banknotes in the withdrawing unit 12. The depositing unit 11 and the withdrawing unit 12 are provided with their positions in the height direction overlapped, and their positions in the front-rear direction are also overlapped. Behind the withdrawing unit 12 on the upper surface of the banknote processing device 10, a touch panel type operation display unit 14 (display unit) for receiving an operator's operation input and displaying to the operator and an arithmetic unit 15 for controlling the entire banknote processing device 10 are provided. The operation display unit 14 displays an operation screen of the banknote processing device 10 and an information screen regarding the operating status.

[0016] Behind the depositing unit 11, a discrimination unit 17 for discriminating banknotes is provided with its height position overlapping that of the depositing unit 11. Behind this discrimination unit 17, a temporary storage unit 18 for temporarily storing the banknotes discriminated by the discrimination unit 17 is provided with its height position overlapping those of the depositing unit 11 and the discrimination unit 17. The lower part of the depositing unit 11 and the upper part of the discrimination unit 17 are provided with their height positions overlapping each other, and the upper part of the depositing unit 11 and the lower part of the discrimination unit 17 are provided with their height positions shifted from each other. The entire discrimination unit 17 and the middle part to the lower part of the temporary storage unit 18 have their height positions overlapping each other, and the upper part of the temporary storage unit 18 is shifted in the height direction with respect to the discrimination unit 17. The upper part of the temporary storage unit 18 has its height position overlapping that of the lower part of the dispensing unit 12. The depositing unit 11, the discrimination unit 17, and the temporary storage unit 18 are arranged in the order of the depositing unit 11, the discrimination unit 17, and the temporary storage unit 18 from the front to the rear of the apparatus. The depositing unit 11 and the discrimination unit 17 are completely shifted in the front-rear direction, and the discrimination unit 17 and the temporary storage unit 18 are completely shifted in the front-rear direction.

[0017] In the depositing unit 11, a placement plate 19 is provided in a rearwardly inclined posture, and this placement plate 19 rises in the rearwardly upward direction and descends in the forwardly downward direction within the depositing unit 11. Banknotes in an accumulated state are placed on the placement plate 19 in the descending state from the outside, and the banknotes placed on the placement plate 19 are in a state of being accumulated in the rearwardly upward direction. The placement plate 19 rises to convey the accumulated banknotes in the rearwardly upward direction, and feeds out the accumulated banknotes one by one from the ones at the upper end in the accumulation direction into the interior of the paper sheet processing apparatus 10.

[0018] The paper sheet processing apparatus 10 internally has a conveying mechanism 20 for conveying banknotes among the depositing unit 11, the dispensing unit 12, the discrimination unit 17, the temporary storage unit 18, a front cassette 51 described later, and a plurality of storage bins 52.

[0019] The transport mechanism 20 has a deposit transport path 21 that extends from the rear end portion of the deposit section 11 and transports the banknotes fed out from the deposit section 11 to the identification section 17. The deposit transport path 21 has an inclined transport path section 22 that extends rearward and downward from the deposit section 11, and a horizontal transport path section 23 that extends horizontally rearward 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 portion of the horizontal transport path section 23.

[0020] Within the identification section 17, the transport mechanism 20 has an internal transport path 25 that is arranged on the same straight line as the horizontal transport path section 23 of the deposit transport path 21 and extends horizontally rearward from the rear end portion of the horizontal transport path section 23. The internal transport path 25 continues to transport the banknotes rearward from the horizontal transport path section 23. The identification section 17 identifies the authenticity, integrity, denomination, double feed, skew, etc. of the banknotes being transported in the internal transport path 25.

[0021] The transport mechanism 20 has a linear transport path 26 that extends horizontally rearward from the rear end portion of the internal transport path 25 in the identification section 17, and the rear end portion of this linear transport path 26 is connected to the temporary storage section 18. The linear transport path 26 continues to transport the banknotes rearward from the internal transport path 25. The horizontal transport path section 23 of the deposit transport path 21, the internal transport path 25, and the linear transport path 26 are aligned on the same straight line, and the identification section 17 and the temporary storage section 18 are connected by the linear transport path 26 that is in a straight line. For example, the banknotes inserted into the deposit section 11 are transported from the deposit section 11 toward the identification section 17 via the deposit transport path 21, and after being identified by the identification section 17, they are transported to the temporary storage section 18 via the linear transport path 26. As described above, the identification section 17 and the temporary storage section 18 overlap in the height direction, and the linear transport path 26 extends in the lateral direction, specifically the horizontal direction, to connect them.

[0022] The temporary storage unit 18 stores banknotes. It takes in and stores the banknotes conveyed along the linear conveyance path 26 one by one, and feeds out the stored banknotes to the linear conveyance path 26 one by one. The temporary storage unit 18, for example, temporarily stores the banknotes inserted into the deposit unit 11 and feeds out the temporarily stored banknotes. As shown in FIG. 2, the temporary storage unit 18 is a winding storage unit that winds and stores the banknotes S one by one at intervals together with the tape 30 around the drum 31 (rotating body). Therefore, the stored banknotes S are unwound from the drum 31 together with the tape 30 and fed out while being counted one by one at intervals. In other words, the temporary storage unit 18 has a drum 31 configured to be able to wind the banknotes S one by one, and the drum 31 feeds out the wound banknotes S one by one.

[0023] The temporary storage unit 18 feeds out the banknotes S in the reverse order of the order when storing them. For this reason, even when banknotes S of multiple denominations are randomly mixed and stored, the arithmetic unit 15 can grasp the denomination of each banknote S to be stored from the identification result of the identification unit 17. Therefore, the denomination of each banknote S fed out from the temporary storage unit 18 can be grasped.

[0024] The drum 31 of the temporary storage unit 18 is provided rotatably around the rotation axis. When the drum 31 rotates in one direction (clockwise in FIGS. 1 and 2) around the rotation axis, the tape 30 is wound up. In the drum 31, as the tape 30 is wound up, the banknotes S are sandwiched and held one by one between the wound tapes 30. Also, in the temporary storage unit 18, by rotating the drum 31 in the other direction (counterclockwise in FIGS. 1 and 2, corresponding to the feeding direction D1 described later) around the rotation axis to feed out the wound tape 30, the banknotes S held between the fed-out tapes 30 are fed out one by one. In the embodiment, for example, the maximum number of banknotes S that can be stored in the temporary storage unit 18 is 600.

[0025] Hereinafter, the structure of the temporary storage unit 18 will be specifically described. As shown in FIG. 3, in the vicinity of the drum 31 that stores and feeds out the banknote S, a pressing roller 32 and a scraper 33 are provided. Note that reference numeral 34 is a reel that feeds out the tape 30, and reference numeral 35 is a regulating roller that regulates the trajectory of the tape 30.

[0026] The pressing roller 32 is formed in a substantially drum shape with the central portion 32a having a larger diameter than the left and right end portions 32b. The pressing roller 32 is arranged at a position where the tape 30 is wound around the drum 31 when viewed from the side and is substantially Consistent positioned as such. The pressing roller 32 is disposed between the two tapes 30. That is, the pressing roller 32 presses the banknote S toward the drum 31 between the two tapes 30.

[0027] Further, the pressing roller 32 is arranged such that the central portion 32a corresponds to the notch portion 31a provided at the center of the drum 31. The pressing roller 32 is preferably rotatably supported around the support shaft 36 so as to smoothly contact the fed-out banknote S.

[0028] As shown in FIGS. 4 and 5, the support shaft 36 is swingable according to the number of banknotes S accommodated, and the outer peripheral surface of the pressing roller 32 can always contact the banknote S accommodated on the outermost periphery of the drum 31 regardless of the storage amount of the banknotes S.

[0029] As shown in FIG. 3, the scraper 33 is disposed on the downstream side of the pressing roller 32 in the feeding direction D1 for feeding out the banknote S when viewed from the side. The scraper 33 is provided corresponding to the two tapes 30. The two scrapers 33 are connected via a support shaft 33a.

[0030] As shown in FIGS. 4 and 5, the scraper 33 is swingable about the support shaft 33a according to the number of banknotes S accommodated, and the tip 33b of the scraper 33 is positioned in the vicinity of the banknotes S accommodated on the outermost periphery of the drum 31 regardless of the storage amount of the banknotes S. The banknotes S wound around the drum 31 together with the tape 30 are peeled off from the drum 31 so as to ride over the tip 33b after the drum 31 rotates in the pay-out direction D1 and the winding by the tape 30 is released, and then are transferred to the rear-side conveyance path portion 26b, which will be described later, via between the tape 30 and the scraper 33.

[0031] Note that, in order to support the banknotes S wound around the drum 31, a support roller (not shown) that abuts against the tape 30 wound around the drum 31 may be provided.

[0032] As shown in FIG. 1, the conveyance mechanism 20 has a pay-out conveyance path 37 that branches upward from an intermediate position of the linear conveyance path 26, and this pay-out conveyance path 37 is connected to the pay-out portion 12. By the branching of the pay-out conveyance path 37, the linear conveyance path 26 is divided into a front-side conveyance path portion 26a on the front side from the branching position of the pay-out conveyance path 37 and a rear-side conveyance path portion 26b on the rear side from the branching position of the pay-out conveyance path 37. The banknotes S can move back and forth between the front-side conveyance path portion 26a and the rear-side conveyance path portion 26b, the banknotes S can be conveyed from the front-side conveyance path portion 26a to the pay-out conveyance path 37 between the front-side conveyance path portion 26a and the pay-out conveyance path 37, and the banknotes S can be conveyed from the rear-side conveyance path portion 26b to the pay-out conveyance path 37 between the rear-side conveyance path portion 26b and the pay-out conveyance path 37.

[0033] The pay-out conveyance path 37 conveys the banknotes S conveyed in the linear conveyance path 26 to the pay-out portion 12, and includes a vertical conveyance path portion 35a that extends vertically upward from an intermediate position of the linear conveyance path 26, a horizontal conveyance path portion 35b that extends horizontally forward from the upper end portion of the vertical conveyance path portion 35a, a vertical conveyance path portion 35c that extends vertically upward from the front end portion of the horizontal conveyance path portion 35b, and a horizontal conveyance path portion 35d that extends horizontally forward from the upper end portion of the vertical conveyance path portion 35c and is connected to the pay-out portion 12.

[0034] Here, the payout unit 12 obliquely accumulates the banknotes S fed out from the horizontal feed path portion 35d of the payout conveyance path 37 from the front and lower sides to the rear and upper sides. The banknotes S accumulated in the payout unit 12 are taken out from the payout unit 12 to the outside. The payout conveyance path 37 conveys, for example, the banknotes S fed out from the temporary storage unit 18 to the linear conveyance path 26 upward from the middle of the linear conveyance path 26 and conveys them to the payout unit 12.

[0035] The deposit unit 11, the payout unit 12, the operation display unit 14, the identification unit 17 including the internal conveyance path 25, the temporary storage unit 18, the deposit conveyance path 21, the linear conveyance path 26, and the payout conveyance path 37 are provided in the upper unit 41 that constitutes the upper part of the sheet processing apparatus 10.

[0036] In the lower unit 42 that is below the upper unit 41 and constitutes the middle to lower part of the sheet processing apparatus 10 in the height direction, a front cassette 51 is provided at the front position, and behind the front cassette 51, a total of eight storage bins 52 are provided in two upper and lower stages and four front and rear rows. Among the eight storage bins 52, the four upper-stage bins have the same height position, and the four lower-stage bins also have the same height position. The height of the front cassette 51 is equivalent to the height of two storage bins 52, and the front cassette 51 overlaps the storage bins 52 in the upper and lower two stages in the height direction.

[0037] The conveying mechanism 20 has a vertical conveying path 55 that branches downward from an intermediate position of the horizontal conveying path portion 23 of the deposit conveying path 21, and this vertical conveying path 55 extends vertically downward from the horizontal conveying path portion 23 and is connected to the front cassette 51. By the branching of the vertical conveying path 55, the horizontal conveying path portion 23 of the deposit conveying path 21 is divided into a front-side front component portion 23a from the branching position of the vertical conveying path 55 and a rear-side rear component portion 23b from the branching position of the vertical conveying path 55. Between the front component portion 23a and the rear component portion 23b, it is possible to convey the banknote S from the front component portion 23a to the rear component portion 23b, and between the vertical conveying path 55 and the rear component portion 23b, the banknote S can go back and forth. The vertical conveying path 55, for example, branches and conveys downward from the middle of the deposit conveying path 21 on the side opposite to the linear conveying path 26 of the identification unit 17 after the banknote S fed out from the temporary storage unit 18 to the linear conveying path 26 passes through the identification unit 17, and stores it in the front cassette 51.

[0038] The front cassette 51 can take in and store the banknotes S one by one, and can feed out the stored banknotes S one by one. The front cassette 51 is an integrated storage unit that receives the banknotes S from above and accumulates them from bottom to top in a horizontal state for storage, and feeds out the stored banknotes S starting from the uppermost one. The front cassette 51 has a significantly higher storage efficiency of the banknotes S compared to a winding storage unit such as the temporary storage unit 18 and the storage bin 52 described later. On the other hand, a winding storage unit such as the temporary storage unit 18 and the storage bin 52 described later has a lower possibility of causing double feeding of the banknotes S compared to the front cassette 51 which is an integrated storage unit, and can accurately separate the stored banknotes S one by one and feed them out at intervals.

[0039] The conveying mechanism 20 has a storage conveying path 57 that branches rearward from an intermediate position of the vertical conveying path 55. This storage conveying path 57 extends horizontally rearward from the vertical conveying path 55, then extends downward near the rear end portion of the paper sheet processing apparatus 10 and is connected to the upper-stage storage bin 52 at the rear end. It is also connected to the lower-stage storage bin 52 at the rear end via this storage bin 52. Due to the branching of the storage conveying path 57, the vertical conveying path 55 is divided into an upper-side conveying path portion 55a above and a lower-side conveying path portion 55b below at the branching position of the storage conveying path 57.

[0040] The conveying mechanism 20 has a plurality of, specifically three, branch conveying paths 61, 62, and 63 that branch downward from an intermediate position of the storage conveying path 57. The branch conveying paths 61, 62, and 63 are connected to the upper-stage storage bins 52 in the front three rows, and are connected to the lower-stage storage bins 52 in the same row via the respective upper-stage storage bins 52.

[0041] Each of the eight storage bins 52 is a winding storage unit that winds and stores the banknotes S one by one at intervals together with a tape 70 described later around a drum 71. Therefore, the held banknotes S are unwound from the drum 71 together with the tape 70 and fed out while being counted one by one at intervals. The storage bin 52 feeds out the banknotes S in the reverse order of the order when holding. For this reason, even when a plurality of denominations of banknotes S are randomly mixed and stored in one unit, the arithmetic unit 15 can grasp the denominations of the respective banknotes S to be stored from the identification results of the identification unit 17, and thus can grasp the denominations of the respective banknotes S fed out from the storage bin 52.

[0042] Hereinafter, the structure of the storage bin 52 will be specifically described. As shown in FIG. 6, a pressing roller 72 and a scraper 73 are arranged near the drum 71 that holds and feeds out the banknotes S. Note that reference numeral 74 is a reel that feeds out the tape 70, and reference numeral 75 is a regulating roller that regulates the trajectory of the tape 70.

[0043] The pressing roller 72 is formed in a substantially drum shape with the central portion 72a having a larger diameter than the left and right end portions 72b. The pressing roller 72 is arranged at a position where the tape 70 is wound around the drum 71 as viewed from the side and is substantially Consistent arranged in such a manner. The pressing roller 72 is arranged between the two tapes 70. That is, the pressing roller 72 presses the banknote S toward the drum 71 between the two tapes 70.

[0044] Further, the pressing roller 72 is arranged such that the central portion 72a corresponds to the notch portion 71a provided at the center of the drum 71. The pressing roller 72 is preferably rotatably supported around the support shaft 76 so as to smoothly contact the fed banknote S.

[0045] As shown in FIGS. 7 and 8, the support shaft 76 is swingable according to the number of accommodated banknotes S, and the outer peripheral surface of the pressing roller 72 can always contact the banknote S accommodated at the outermost periphery of the drum 71 regardless of the storage amount of the banknotes S.

[0046] As shown in FIG. 6, the scraper 73 is arranged on the downstream side of the pressing roller 72 in the feeding direction D2 in which the banknote S is fed as viewed from the side. The scraper 73 is provided corresponding to the two tapes 70. The two scrapers 73 are connected via the support shaft 73a.

[0047] As shown in FIGS. 7 and 8, the scraper 73 is swingable around the support shaft 73a according to the number of accommodated banknotes S, and the tip 73b of the scraper 73 is located in the vicinity of the banknote S accommodated at the outermost periphery of the drum 71 regardless of the storage amount of the banknotes S. The banknote S wound around the drum 71 together with the tape 70 is peeled off from the drum 71 so as to ride over the tip 73b when the drum 71 rotates in the feeding direction D2 and the winding by the tape 70 is released, and then is transferred to the branch conveyance paths 61 to 63 or the storage conveyance path 57 through between the tape 70 and the scraper 73.

[0048] Note that a support roller (not shown) that abuts on the tape 70 wound around the drum 71 may be provided to support the banknote S wound around the drum 71.

[0049] The storage and conveyance path 57 and the branch conveyance paths 61, 62, and 63 branch and convey downward the banknote S that has been fed out from the temporary storage unit 18 to the linear conveyance path 26 and passed through the identification unit 17, from the middle of the deposit conveyance path 21, and branch and convey rearward from the middle of the vertical conveyance path 55, and selectively store it in the eight storage bins 52. The eight storage bins 52 can be set, for example, such that all eight are single-denomination storage bins each storing only banknotes S of a single set denomination, or some of them can be set as single-denomination storage bins each storing only banknotes S of a single set denomination, and the rest can be set as denomination-mixed storage bins each storing banknotes S of multiple denominations in a denomination-mixed manner.

[0050] The lower unit 42 is provided with a front cassette 51, eight storage bins 52, the lower part of the upper conveyance path section 55a of the vertical conveyance path 55, the lower conveyance path section 55b, the storage and conveyance path 57, and the branch conveyance paths 61 to 63. The upper part of the upper conveyance path section 55a of the vertical conveyance path 55 is provided in the upper unit 41.

[0051] The lower unit 42 has a rectangular parallelepiped box-shaped housing 77 that opens forward, a unit main body 78 in which eight storage bins 52 are provided and arranged in 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 provided with respect to the unit main body 78.

[0052] As shown in FIG. 2, the arithmetic unit 15 includes a control unit 81 that performs drive control of the deposit unit 11, the temporary storage unit 18, the conveyance mechanism 20, the front cassette 51, and the plurality of storage bins 52 shown in FIG. 1 of the sheet processing apparatus 10, a calculation unit 82 that calculates the number of banknotes S that can be stored in the temporary storage 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 operation mode of the sheet processing apparatus 10 in response to an operation input to the operation display unit 14.

[0053] The control unit 81 performs, for example, the feeding control of the banknote S in the depositing unit 11, the feeding control of the banknote S in the temporary storage unit 18, the conveyance control by the conveyance mechanism 20 of the banknote S inserted into the depositing unit 11 and fed out from the depositing unit 11, and the conveyance control by the conveyance mechanism 20 of the banknote S fed out from the temporary storage unit 18. The control unit 81 also performs, for example, the control of batch processing such as feeding out the banknotes S stored in the temporary storage unit 18 in batch numbers and dividing them into the paying-out unit 12 for paying out. In batch processing, the control unit 81 stores the maximum number of banknotes S that can be stored in the temporary storage unit 18, calculated by the calculation unit 82, in the temporary storage unit 18 from among the banknotes S inserted into the depositing unit 11.

[0054] Next, the main operations of the document processing apparatus 10 according to the present embodiment will be described.

[0055] The mode switching unit 84 of the arithmetic unit 15 switches the operation mode of the document processing apparatus 10 according to an operation input to the operation display unit 14. In the embodiment, there are a storage mode in which a plurality of banknotes S inserted into the depositing unit 11 are classified by denomination and distributed and stored in the storage bins 52 determined for each denomination, a paying-out mode in which banknotes S are taken out from the plurality of storage bins 52 to the paying-out unit 12 so as to be payable, and a counting mode in which banknotes S of the same specific denomination are counted in preset batch numbers from the plurality of banknotes S inserted into the depositing unit 11, divided into batch numbers, and paid out to the paying-out unit 12, and the mode is switched among them.

[0056] In other words, the mode switching unit 84 appropriately repeats, for the sheet processing apparatus 10, the counting mode of counting a preset batch number of the plurality of banknotes S inserted into the depositing unit 11 and conveying them to the dispensing unit 12, the storing mode of classifying and storing the plurality of banknotes S inserted into the depositing unit 11 for each predetermined type, and the dispensing mode of dispensing the banknotes S of the designated type so that they can be taken out from the dispensing unit 12. The sheet processing apparatus 10 is switched to the storing mode, the dispensing mode, and the counting mode by the mode switching unit 84 according to an operation on the operation display unit 14 by the operator. Note that the operation modes of the sheet processing apparatus 10 are not limited to these three operation modes, and it may have other operation modes.

[0057] When the mode switching unit 84 switches the sheet processing apparatus 10 to the storing mode in response to an operation input to the operation display unit 14, the control unit 81 performs the following depositing process and storing process, or depositing process and returning process, according to the operation input to the operation display unit 14.

[0058] [Depositing Process] When it is detected by a sensor (not shown) that a banknote S has been externally inserted into the depositing unit 11 and an operation to start the depositing process is input to the operation display unit 14, the sheet processing apparatus 10 is controlled by the control unit 81 to convey the banknote S through the depositing process route indicated by the thick line in FIG. 9 by the depositing unit 11 and the conveying mechanism 20.

[0059] That is, the depositing unit 11 separates the banknotes S one by one, feeds them out at a predetermined interval, and the fed-out banknotes S are conveyed by the depositing conveyance path 21 of the conveyance mechanism 20, the internal conveyance path 25 of the discrimination unit 17, and the front-side conveyance path section 26a of the linear conveyance path 26. During the conveyance in the internal conveyance path 25, the discrimination unit 17 discriminates the banknotes S, and the banknotes S discriminated as acceptable by the discrimination unit 17 are conveyed from the front-side conveyance path section 26a of the linear conveyance path 26 to the rear-side conveyance path section 26b, and the rear-side conveyance path section 26b conveys them to the temporary storage unit 18, and the temporary storage unit 18 stores them (refer to the thick solid line in FIG. 9). On the other hand, for the banknotes S discriminated as unacceptable by the discrimination unit 17, they are conveyed from the front-side conveyance path section 26a of the linear conveyance path 26 to the discharging conveyance path 37, and the discharging conveyance path 37 conveys them to the discharging unit 12 (refer from the thick solid line to the thick broken line in FIG. 9).

[0060] Here, since the depositing unit 11 separates and feeds out the banknotes S in a stacked state in the thickness direction, there is a possibility of conveyance failures such as double feeding and skewing of the banknotes S during feeding. Such banknotes S with conveyance failures are also discriminated as unacceptable by the discrimination unit 17, and the conveyance mechanism 20 conveys them to the discharging unit 12. The control unit 81, when a banknote S to be conveyed to the discharging unit 12 occurs during the depositing process, accordingly stops the temporary storage unit 18 and controls so that the intake interval between the banknotes S stored in the temporary storage unit 18 becomes constant.

[0061] When all the banknotes S inserted into the depositing unit 11 are conveyed to either the temporary storage unit 18 or the discharging unit 12, the operation display unit 14 displays the denomination-specific number of banknotes, the total amount, and other amount information of the banknotes S temporarily stored in the temporary storage unit 18 based on the discrimination result of the discrimination unit 17. The banknotes S conveyed to the discharging unit 12 can be taken out externally. Separately from the discharging unit 12, a reject unit for making the banknotes S removable externally may be provided, and the unacceptable banknotes S may be conveyed to this reject unit.

[0062] [Storage process] After the operation display unit 14 of the amount information is displayed after the deposit process, when the operator inputs an approval operation to the operation display unit 14, the paper sheet processing apparatus 10 is controlled by the control unit 81, and the temporary holding unit 18, the conveyance mechanism 20, and the eight storage bins 52 convey the banknote S along the storage process route indicated by the thick line in FIG. 10.

[0063] That is, the temporary holding unit 18 feeds out the temporarily stored banknotes S one by one at intervals, and the linear conveyance path 26, the internal conveyance path 25 of the identification unit 17, the rear component 23b of the deposit conveyance path 21, the upper conveyance path portion 55a of the vertical conveyance path 55, and the storage conveyance path 57 convey them. During the conveyance in the internal conveyance path 25, the identification unit 17 identifies the banknote S, and based on the result, the appropriate ones of the storage conveyance path 57 and the branch conveyance paths 61 to 63 distribute the banknote S to the corresponding ones of the eight storage bins 52. The corresponding ones of the eight storage bins 52 store the distributed banknotes S.

[0064] Here, since the temporary holding unit 18 is a winding storage unit, basically, conveyance failures such as double feeding and skewing of the banknote S do not occur during feeding, and basically, there is no banknote S fed out by the temporary holding unit 18 that is determined by the identification unit 17 to be non-storable.

[0065] By the way, when the warped banknote S is fed out from the drum 31, there is a risk that the banknote S may enter between the tip 33b of the scraper 33 and the drum 31 without riding over the tip 33b. Prior to the feeding of the banknote S, the pressing roller 32 corrects the warp of the banknote S, so that the banknote S can be reliably fed out.

[0066] Specifically, when the banknote S is fed out from the temporary holding unit 18, as shown in FIG. 11(a), the pressing roller 32 presses the banknote S immediately before feeding toward the drum 31.

[0067] At this time, as shown in FIG. 11(b), the position where the pressing roller 32 presses the banknote S is directly above the notch 31a and within the range where both ends are wound around the two tapes 30 and stably supported. Also, directly below the position where the pressing roller 32 presses the banknote S, there is a gap corresponding to the thickness of the tape 30 between the upper and lower banknotes S, so the banknote S pressed by the pressing roller 32 is easily bent. As a result, as shown in FIGS. 11(b) and (c), the portion R of the banknote S pressed by the pressing roller 32 bends downward, tension is generated in the banknote S, and the warp of the banknote S is corrected. Then, the banknote S with the warp corrected rides on the tip 33b of the scraper 33 and is fed out from the drum 31, and is transferred to the rear-side conveyance path portion 26b through between the tape 30 and the scraper 33.

[0068] [Return process] After the amount information is displayed on the operation display unit 14 after the deposit process, when the operator inputs a return operation to the operation display unit 14, the paper sheet processing apparatus 10 is controlled by the control unit 81, and the banknote S is conveyed along the return process route shown by the thick line in FIG. 12 by its temporary storage unit 18, conveyance mechanism 20, and payout unit 12.

[0069] That is, the temporarily stored banknotes S are fed out one by one at intervals by the temporary storage unit 18 and conveyed to the payout unit 12 by the rear-side conveyance path portion 26b of the linear conveyance path 26 and the payout conveyance path 37. The banknotes S conveyed to the payout unit 12 can be taken out externally.

[0070] Here, as shown in FIGS. 11(a) to (c), the banknotes S fed out from the temporary storage unit 18 are bent at the portions pressed by the pressing roller 32 and the warp is corrected, so they are fed out from the drum 31 so as to ride on the tip 33b of the scraper 33 and are transferred to the rear-side conveyance path portion 26b.

[0071] When the mode switching unit 84 switches the paper sheet processing apparatus 10 to the payout mode in response to an operation input to the operation display unit 14, the control unit 81 performs the following payout process in response to the operation input to the operation display unit 14.

[0072] [Withdrawal Processing] When a selection operation for withdrawal processing is input to the operation display unit 14 together with the amount information of the banknote S to be withdrawn, when withdrawing the banknote S from the storage bin 52 set in the single-denomination storage bin, the paper sheet processing apparatus 10 is controlled by the control unit 81, and the banknote S of the denomination to be withdrawn is transported from the storage bin 52 in which the banknote S is stored, by the transport mechanism 20 and the withdrawal unit 12, along the withdrawal processing route shown by the thick line in FIG. 13.

[0073] That is, the corresponding one of the storage bins 52 feeds out the stored banknotes S one by one, counting them while leaving a gap, and the fed-out banknotes S are transported to the withdrawal unit 12 by an appropriate one of the branch transport paths 61 to 63, the storage transport path 57, the upper transport path portion 55a of the vertical transport path 55, the rear configuration portion 23b of the deposit transport path 21, the internal transport path 25 of the identification unit 17, the front transport path portion 26a of the linear transport path 26, and the withdrawal transport path 37. Here, since all the storage bins 52 are winding storage units, basically, no transport defects such as double feeding or skewing of the banknotes S occur during feeding, and basically, there is no banknote S fed out by the storage bin 52 that is determined to be non-withdrawable by the identification unit 17. The banknote S transported to the withdrawal unit 12 can be taken out externally.

[0074] By the way, when a warped banknote S is fed out from the drum 71, there is a possibility that the banknote S may enter between the tip 73b of the scraper 73 and the drum 71 without riding over the tip 73b. Prior to the feeding of the banknote S, the pressing roller 72 corrects the warp of the banknote S, so that the banknote S can be reliably transferred.

[0075] Specifically, in the same manner as when the pressing roller 32 shown in FIGS. 11(a) to 11(c) corrects the warp of the banknote S, first, when the banknote S is fed out from the storage 52, the pressing roller 72 presses the fed-out banknote S toward the drum 71. The position where the pressing roller 72 presses the banknote S is directly above the notch 71a and within the range where both ends are wound around the two tapes 70 and stably supported. Also, directly below the position where the pressing roller 72 presses the banknote S, there is a gap corresponding to the thickness of the tape 70 between the upper and lower banknotes S, so the banknote S pressed by the pressing roller 72 is easily bent. As a result, the portion R of the banknote S pressed by the pressing roller 72 is bent, tension is generated in the banknote S, and the warp of the banknote S is corrected. Then, the banknote S with the warp corrected is fed out from the drum 71 so as to ride on the tip 73b of the scraper 73 and is transferred to the branch conveyance paths 61 to 63 or the storage conveyance path 57 through between the tape 70 and the scraper 73.

[0076] Here, during this withdrawal process, the banknotes fed out from the corresponding one of the storages 52 and identified as soiled banknotes by the identification unit 17 are stored in the innermost area of the winding of the temporary holding unit 18.

[0077] When the mode switching unit 84 switches the paper sheet processing apparatus 10 to the counting mode in response to an operation input to the operation display unit 14, the control unit 81 performs the following batch process in response to the operation input to the operation display unit 14.

[0078] [Batch Process] The batch process is a sorting and counting process for sorting and counting the banknotes S. An input operation of type information such as the denomination of the banknotes S to be batch-processed and a predetermined batch number Nk is input to the operation display unit 14. Here, the batch number Nk means a predetermined number of banknotes S to be bundled, and may be set in advance by the operator or automatically set by the paper sheet processing apparatus 10. When the input operation of the type information of the banknotes S to be batch-processed and the predetermined batch number Nk is input, the calculation unit 82 of the arithmetic unit 15 calculates the maximum retainable number Nt of the banknotes S that can be retained in the temporary holding unit 18 from now on.

[0079] Specifically, the calculation unit 82 calculates the maximum number of banknotes S that can be temporarily stored Nt that can be stored in the temporary storage unit 18 at the current time based on the maximum number of banknotes S that can be physically stored to the maximum extent when the temporary storage unit 18 is empty Nmax and the number of banknotes S that are already stored in the temporary storage unit 18 at the current time Ndt. In other words, the calculation unit 82 calculates the maximum number of banknotes S that can be stored Nt that can be stored in the temporary storage unit 18 at the current time based on the maximum number of banknotes S that can be stored in the empty temporary storage unit 18 Nmax and the number of banknotes S that are currently stored in the temporary storage unit 18 Ndt.

[0080] Here, the temporary storage unit 18 stores the banknotes identified as damaged banknotes by the identification unit 17 during the withdrawal process in the innermost area of the winding. In this case, the number Ndt is the number of these damaged banknotes.

[0081] The number of banknotes that can be stored Nt is calculated by subtracting the number of banknotes S that are already stored in the temporary storage unit 18 at the current time Ndt from the maximum number of banknotes S that can be stored in the temporary storage unit 18 Nmax (Nt = Nmax - Ndt). Therefore, when no banknotes S are stored in the temporary storage unit 18, the maximum number of banknotes that can be stored Nmax in the temporary storage unit 18 becomes the number of banknotes that can be stored Nt at the current time (Nmax = Nt). Information regarding the number of banknotes that can be stored Nt calculated by the calculation unit 82 is transmitted to the control unit 81. If the number of banknotes that can be stored Nt received from the calculation unit 82 is less than the batch number Nk, the control unit 81 causes the operation display unit 14 to display to that effect, stating that batch processing cannot be performed.

[0082] (Forward path processing) When the number of banknotes that can be stored Nt received from the calculation unit 82 is equal to or greater than the batch number Nk, the control unit 81 performs drive control of the deposit unit 11, the transport mechanism 20, and the temporary storage unit 18 based on the information regarding the number of banknotes that can be stored Nt on the condition that the sensor (not shown) has detected the banknotes S in the deposit unit 11, and performs the forward path processing of the batch processing to transport the plurality of banknotes S inserted into the deposit unit 11 through the forward path processing route of the batch processing that is the same as the deposit processing route shown by the thick line in FIG. 9.

[0083] That is, the depositing unit 11 separates the banknotes S one by one, feeds them out at intervals, and the fed-out banknotes S are conveyed by the depositing conveyance path 21 of the conveyance mechanism 20, the internal conveyance path 25 of the identification unit 17, and the front-side conveyance section 26a of the linear conveyance path 26. During the conveyance in the internal conveyance path 25, the identification unit 17 identifies and counts the banknotes S, and the banknotes S identified by the identification unit 17 as being the batch processing target are conveyed to the temporary storage unit 18 by the front-side conveyance section 26a and the rear-side conveyance section 26b of the linear conveyance path 26 to the maximum extent within the range up to the retainable number Nt, and are stored in the temporary storage unit 18 (refer to the thick solid line in FIG. 9).

[0084] At this time, the control unit 81 drives and controls the temporary storage unit 18 to wind up and store the banknotes S conveyed by the conveyance mechanism 20 one by one at intervals together with the tape 30 on the drum 31. At that time, the banknotes S identified as being the batch processing target are stored on the winding front side of the already stored banknotes S counted as the number Ndt. As a result, for example, when there are banknotes S that are the batch processing target in a number exceeding the batch number Nk in the depositing unit 11, the temporary storage unit 18 temporarily stores the banknotes S that are the batch processing target in a number exceeding the batch number Nk.

[0085] On the other hand, the banknotes S identified by the identification unit 17 as not being the batch processing target are conveyed from the front-side conveyance section 26a of the linear conveyance path 26 to the discharging conveyance path 37 and then to the discharging unit 12 (refer to the change from the thick solid line to the thick broken line in FIG. 9). Also here, in addition to the banknotes S whose type information is different from the specification, the banknotes S with conveyance defects are also identified by the identification unit 17 as not being the batch processing target, and are conveyed by the conveyance mechanism 20 to the discharging unit 12. Note that, separately from the discharging unit 12, a reject unit for making it possible to take out the banknotes S to the outside may be provided, and the banknotes S identified as not being the batch processing target may be conveyed to this reject unit. Here, when banknotes S to be conveyed to the discharging unit 12 occur, the control unit 81 accordingly stops the temporary storage unit 18 and controls so that the intervals of the banknotes S stored in the temporary storage unit 18 become constant.

[0086] When it is predicted that the number of banknotes S held in the temporary storage unit 18 will reach the maximum number of banknotes Nt that can be stored during the current forward path process, or when it is detected by a sensor (not shown) that all the banknotes S inserted into the depositing unit 11 have been used up, and then when all these banknotes S have been transported to either the temporary storage unit 18 or the dispensing unit 12, the control unit 81 stops the depositing unit 11, the transport mechanism 20, and the temporary storage unit 18. At this time, the banknotes S transported to the dispensing unit 12 can be taken out externally.

[0087] Then, the display information generation unit 83 of the arithmetic device 15 generates information to be displayed on the operation display unit 14 based on the identification result of the identification unit 17 and transmits it to the operation display unit 14. Here, the display information generation unit 83 generates operation screen information for displaying operation buttons and the like when the operator uses the paper sheet processing device 10 on the operation display unit 14 and transmits it to the operation display unit 14. As a result, the operation display unit 14 displays an operation screen used for the operator's operation based on the operation screen information generated by the display information generation unit 83. In addition, the display information generation unit 83 generates operation status information of the paper sheet processing device 10. For example, the operation status information includes information regarding the number of banknotes S held in the temporary storage unit 18 during the current forward path process and information regarding the batch number Nk (for example, 100 sheets).

[0088] Here, when the display information generation unit 83 determines that the number of banknotes S held in the temporary storage unit 18 during the current forward path process is equal to or greater than the batch number Nk (first state) set by the operator, it displays the character of the batch number Nk (for example, 100 sheets) to be displayed in the display area 14c of the operation display unit 14 in black, indicating that it is possible to dispense the banknotes S of the batch number Nk.

[0089] On the other hand, when the display information generation unit 83 determines that the number of banknotes S held in the temporary holding unit 18 in the current forward path process is less than the batch number Nk (second state) set by the operator, the character of the batch number Nk (for example, 100 sheets) displayed in the display area 14c of the operation display unit 14 is displayed in a display mode different from the case where the number of banknotes S currently held in the temporary holding unit 18 is equal to or more than the batch number Nk, for example, in orange, to indicate that the payment of the banknotes S of the batch number Nk cannot be made.

[0090] That is, the display information generation unit 83 causes the operation display unit 14 to display the operating status of the paper sheet processing apparatus 10 in different display modes in a first state where the number of banknotes S held in the temporary holding unit 18 in the current forward path process is equal to or more than the preset batch number Nk and a second state where the number of banknotes S held in the temporary holding unit 18 in the current forward path process is less than the preset batch number Nk. When the number of banknotes S held in the temporary holding unit 18 in the current forward path process is less than the batch number Nk, it is not limited to the above-described display mode. For example, the character of the batch number may be blinked, the display color may be lightened, or it may be notified by voice or the like that the number is less than the batch number.

[0091] (Reverse path process) After the display on the operation display unit 14 after the above-described forward path process, when the operator inputs an execution operation for the reverse path process to the operation display unit 14, the control unit 81 performs drive control of the temporary holding unit 18 and the transport mechanism 20, and performs a reverse path process of batch processing in which the banknotes S are transported from the temporary holding unit 18 to the payout unit 12 in batches of the batch number Nk in the same reverse path process of batch processing as the return processing route indicated by the thick line in FIG. 12.

[0092] That is, the temporarily stored banknotes S are separated one by one by the temporary holding unit 18, fed out with an interval, and transported to the payout unit 12 through the rear feed path portion 26b of the linear transport path 26 and the payout transport path 37. The banknotes S transported to the payout unit 12 are accumulated at the payout unit 12.

[0093] Here, as shown in FIGS. 11(a) to 11(c), the banknote S fed out from the temporary storage unit 18 is fed out from the drum 31 so as to ride on the tip 33b of the scraper 33 because the portion R pressed by the pressing roller 32 is bent and the warp is corrected, and is transferred to the rear conveying path unit 26b.

[0094] When the number of banknotes S fed out from the temporary storage unit 18 reaches 100, which is the batch number Nk, the control unit 81 temporarily stops the temporary storage unit 18, and when the banknotes S fed out from the temporary storage unit 18 reach the batch number Nk at the payout unit 12, the control unit 81 temporarily stops the drive of the transport mechanism 20. Then, the display information generation unit 83 causes the operation display unit 14 to display the type of the banknotes S paid out at the payout unit 12, the batch number Nk of 100 thereof, and a display prompting the operator to take them out. Thereby, the operator takes out the banknotes S of the batch number Nk in the payout unit 12 from the payout unit 12.

[0095] Then, a sensor (not shown) detects that the banknotes S in the payout unit 12 have been taken out. Accordingly, the control unit 81 determines whether the total number of banknotes S fed out from the temporary storage unit 18 to the payout unit 12 in the current batch process, that is, the total number of fed-out banknotes, is equal to the number of banknotes S stored in the temporary storage unit 18 in the current batch process.

[0096] That is, when it is determined that the total number of banknotes S fed out from the temporary storage unit 18 in the return path process up to the current batch process is less than the number of banknotes S stored in the temporary storage unit 18 in the forward path process of the current batch process, and the difference between them is equal to or greater than the batch number Nk, the control unit 81 performs the drive control of the temporary storage unit 18 and the transport mechanism 20 again in the same manner as described above, and conveys the banknotes S to the payout unit 12 by the batch number Nk along the return path of the batch process shown by the thick line in FIG. 12.

[0097] After that, the display information generation unit 83 causes the operation display unit 14 to display the type of the banknote S withdrawn by the withdrawal unit 12, the batch number Nk thereof, which is 100 sheets, and a display prompting the operator to take out the banknote. As a result, the operator takes out the banknote S of the batch number Nk in the withdrawal unit 12 from the withdrawal unit 12.

[0098] By appropriately repeating such processing, when it is determined that the total number of banknotes S fed out from the temporary storage unit 18 in the return path processing up to that point in the current batch processing is less than the number of banknotes S stored in the temporary storage unit 18 in the forward path processing of the current batch processing, and the difference between these is less than the batch number Nk, the control unit 81 changes the display mode of the character of the batch number Nk displayed in the display area 14c to be displayed in orange different from the black color until then, and again drives and controls the temporary storage unit 18 and the transport mechanism 20 in the same manner as above, and transports all the banknotes S remaining stored in the temporary storage unit 18 in the forward path processing of the current batch processing to the withdrawal unit 12 through the return path of the batch processing shown by the thick line in FIG. 12.

[0099] Then, when the total number of banknotes S fed out from the temporary storage unit 18 to the withdrawal unit 12, which is the total number of fed-out banknotes, becomes the number of banknotes stored in the temporary storage unit 18 in the current batch processing, the control unit 81 stops the temporary storage unit 18, and stops the drive of the transport mechanism 20 at the timing when all the banknotes S fed out by the temporary storage unit 18 are withdrawn to the withdrawal unit 12.

[0100] At the same time, the display information generation unit 83 causes the operation display unit 14 to display the type of the banknote S withdrawn by the withdrawal unit 12, the remainder less than the batch number Nk, and a display prompting the operator to take out the banknote. As a result, the operator takes out the banknote S of the remaining number in the withdrawal unit 12 from the withdrawal unit 12.

[0101] Then, a sensor (not shown) detects that the banknote S in the withdrawal unit 12 has been taken out. As a result, the control unit 81 determines that the total number of banknotes S fed out from the temporary storage unit 18 to the withdrawal unit 12 in the current batch processing, which is the total number of fed-out banknotes, has become the number of banknotes stored in the temporary storage unit 18 in the current batch processing.

[0102] In this way, the sheet processing apparatus 10 according to the present embodiment includes a temporary storage unit 18 that winds and stores the banknote S together with the tape 30 around the drum 31 and feeds out the stored banknote S. The temporary storage unit 18 includes a pressing roller 32 that presses the banknote S accommodated in the drum 31 toward the drum 31 to correct the warp of the banknote S, and a scraper 33 that peels off the banknote S with the corrected warp from the drum 31. It is configured to include.

[0103] According to this configuration, prior to the feeding out of the banknote S wound and stored around the drum 31 together with the tape 30, the pressing roller 32 corrects the warp of the banknote S, so that the banknote S is steadily peeled off from the drum 31 by the scraper 33. Therefore, the banknote S can be fed out smoothly.

[0104] Further, the sheet processing apparatus 10 according to the present embodiment is configured such that the pressing roller 32 is formed in a substantially drum shape.

[0105] According to this configuration, since the banknote S is smoothly curved along the outer peripheral surface of the pressing roller 32 and the warp is corrected, the banknote S can be fed out smoothly.

[0106] Further, the sheet processing apparatus 10 according to the present embodiment is configured such that two tapes 30 are provided spaced apart in the axial direction of the drum 31, and the pressing roller 32 presses the banknote S toward the drum 31 between the two tapes 30.

[0107] According to this configuration, since the pressing roller 32 is pressed against the banknote S within the range where both ends of the banknote S are wound around the two tapes 30 and stably supported, the warp of the banknote S can be surely corrected.

[0108] Further, the paper sheet processing apparatus 10 according to the present embodiment includes a storage 52 that winds and stores the banknote S around the drum 71 together with the tape 70, and feeds out the stored banknote S. The storage 52 includes a pressing roller 72 that presses the banknote S accommodated in the drum 71 toward the drum 71 to correct the warp of the banknote S, and a scraper 73 that peels off the banknote S with the corrected warp from the drum 71.

[0109] According to this configuration, prior to the feeding out of the banknote S wound around the drum 71 together with the tape 70, the pressing roller 72 corrects the warp of the banknote S, so that the banknote S is smoothly peeled off from the drum 71 by the scraper 73, and thus the banknote S can be fed out smoothly.

[0110] Further, the paper sheet processing apparatus 10 according to the present embodiment is configured such that the pressing roller 72 is formed in a substantially drum shape.

[0111] According to this configuration, the banknote S is smoothly curved along the outer peripheral surface of the pressing roller 72 and the warp is corrected, so that the banknote S can be fed out smoothly.

[0112] Further, the paper sheet processing apparatus 10 according to the present embodiment is configured such that two tapes 70 are provided at intervals in the axial direction of the drum 71, and the pressing roller 72 presses the banknote S toward the drum 71 between the two tapes 70.

[0113] According to this configuration, the pressing roller 72 presses the banknote S within the range where both ends of the banknote S are wound around the two tapes 70 and stably supported, so that the warp of the banknote S can be surely corrected.

[0114] Further, the present invention can be variously modified other than the above as long as it does not depart from the spirit of the present invention, and it is natural that the present invention extends to the modified ones.

[0115] For example, the pressing members for correcting the warp of the banknotes S fed out from the drums 31 and 71 are not limited to the pressing rollers 32 and 72, and other configurations may be used.

[0116] Also, although the sheet processing apparatus 10 that processes banknotes as sheets has been described as an example, the present invention is also applicable to apparatuses that similarly process various sheets such as securities or gift certificates other than banknotes.
