Control signals are output to the conveying section 3, the first to fifth stacking sections 31 to 35, the bill conveying section 36, the banding unit 5, and the reel set section 4. The banknote sorting machine 1 identifies and counts banknotes, sorts them by type, and performs a bundling process of creating bundled banknotes of a predetermined number.

More specifically, in the bundling process, the banknote sorter 1 feeds loose banknotes inserted into the insertion unit 13 one by one, and the recognition unit 18 identifies and counts the banknotes. The banknote transport unit 3 transports banknotes to be bundled to the first to fifth stacking units 31 to 35 based on the identification result, and transports other banknotes to the first external stacking unit 11 or the second external stacking unit 12. transport to Banknotes identified as rejected banknotes are conveyed to the reject section 14 . The first reversing section 21 and the second reversing section 22 appropriately reverse the bills, thereby aligning the front/back and top/bottom directions of the bills stacked in the first to fifth stacking sections 31 to 35 .

When the number of bundled banknotes is stacked in any one of the first to fifth stacking units 31 to 35, the banknote conveying unit 36 takes out the banknotes from the stacking unit and transports the taken-out banknotes to the banding unit. Transport to 51. The bundling unit 51 bundles banknotes, and the bundled banknotes are discharged from the banknote sorter 1 from the second transport unit 52 through the discharge unit 15 .

After all the banknotes inserted into the input unit 13 are taken into the banknote sorter 1, the fractional banknotes remaining in the first to fifth stacking units 31 to 35 without reaching the number of bundled banknotes are returned to the return unit 16. . Specifically, the banknote transport unit 36 takes out the fractional banknotes from the first to fifth stacking units 31 to 35 and transports them to the tray 161 of the return unit 16 . The odd bills are automatically returned to the operator by advancing the tray 161 on which the odd bills are placed. By paying out the fractional banknotes to the outside of the banknote sorter 1, it is possible to prevent the fractional banknotes from being left untaken.

It is also possible to leave the fractional banknotes in the first to fifth stacking units 31 to 35 instead of returning them through the returning unit 16 (so-called leaving operation).

(Structure of reel set part)
FIG. 3 shows a configuration example of the reel set section 4. As shown in FIG. The reel set section 4 includes a mounting section 41 to which a reel 45 of a banded paper 451 is mounted, a part of a banded paper conveying section 42 for conveying the banded paper 451 pulled out from the reel 45 to the banded section 51, and a mounting section. A printing unit 43 for printing on the wrapping paper 451 is provided between the wrapping paper 41 and the wrapping paper conveying unit 42 . The reel set section 4 is an example of a mounting unit.

The mounting portion 41 has a table 411 on which the reel 45 is placed so that the reel axis is oriented vertically. By orienting the reels 45 horizontally, it is advantageous for miniaturization of the banknote sorter 1 . The table 411 is configured to rotate clockwise and counterclockwise around a vertically extending shaft. A reel driving motor 412 is connected to the table 411 via a belt 413 . The reel drive motor 412 rotates the table 411 so that the reel 45 rotates in the winding direction of the band wrapping paper 451 .

The mounting section 41 has an empty sensor 414 that detects the shortage of the banded paper 451 by detecting the outer diameter of the reel 45 . When receiving the detection signal from the empty sensor 414 , the control section 101 prompts the operator to replace the reel 45 via the display section 17 .

The wrapping paper 451 is pulled out horizontally from the reel 45 . The front and back surfaces of the wrapping paper 451 are oriented horizontally. The printing unit 43 is configured by, for example, a dot impact printer. The print head strikes the ink ribbon against the banded paper 451 pulled out in the horizontal direction, thereby printing on the surface of the banded paper 451 (that is, the outer surface of the banded paper 451 wound around the reel 45). will be

A twist guide 44 that twists and guides the banded paper 451 is arranged downstream of the printing unit 43 and upstream of the banded paper conveying unit 42 in the transport direction of the banded paper 451 . The twist guide 44 twists the band wrapping paper 451 with the front and back sides oriented horizontally so that the front side faces upward and the back side faces downward. The twist guide 44 is composed of a first guide 441 and a second guide 442 . Although detailed illustration is omitted, the first guide 441 and the second guide 442 are arranged facing each other on the transport path of the banded paper 451 with a gap through which the banded paper 451 can pass. The gap formed by the first guide 441 and the second guide 442 is formed vertically at the entry port of the banded paper 451 and horizontally at the exit port of the banded paper 451 . The gap changes orientation from vertical to horizontal between the entrance and exit.

The band-wrapped paper conveying unit 42 has a feed roller 421 (see FIGS. 4 and 5) and a feed motor 422 that drives the feed roller 421 .

The feed motor 422 drives the band-wrapped paper 451 sandwiched between the feed rollers 421 so as to feed it to the band-wrapped section 51 . The feed motor 422 is composed of an electric motor. Specifically, the feed motor 422 may be configured by a stepping motor, a DC motor, a brushless motor, or the like. The control unit 101 controls driving and stopping of the feed motor 422 . By driving the feed motor 422 , the banded paper 451 is conveyed upward from the reel set section 4 and supplied to the banded banding unit 5 .

As shown in FIG. 4 and the like, the wrapped paper conveying unit 42 is also provided with a wrapped paper detection sensor 423 that detects the leading edge of the wrapped paper 451 . The banded paper detection sensor 423 is arranged at a position near the banded unit 5 in the reel set section 4 . The bundled paper detection sensor 423 may be composed of, for example, a light-transmissive sensor arranged in the conveying path of the bundled paper 451 . The passage of the leading edge of the wrapping paper 451 can be detected by the light-transmitting and light-shielding sensor detecting a change in light transmission and light shielding.

(Rewinding of wrapping paper)
In the paper sheet bundling mechanism 40 of the banknote sorter 1, a bundling paper 451 straddles between the reel set section 4 and the bundling unit 5 which overlap in the vertical direction. In the band-wrapping unit 5 , the band-wrapped paper 451 is sandwiched between the transport rollers 54 . When the wrapping paper 451 is in this state, the reel set section 4 is pulled out from the banknote sorter 1 as indicated by the dashed line in FIG. If so, the wrapping paper 451 may be pulled out from the reel 45 unnecessarily, or the wrapping paper 451 may be cut in the middle. In this case, the recovery work becomes troublesome. Therefore, the banknote sorter 1 is configured to rewind the banded paper to the reel set section 4 when a predetermined condition is satisfied.

One of the predetermined conditions is that the empty sensor 414 detects that the reel 45 should be replaced. When receiving the detection signal from the empty sensor 414, the control unit 101 urges the operator to replace the reel 45 through the display unit 17 and causes the wrapping paper conveying unit to wind the wrapping paper 451, as described above. Execute the return.

4 and 5 schematically show the procedure for rewinding the wrapping paper 451. FIG. P1 in FIG. 4 shows how a bundle of banknotes is bundled. The tip of the wrapping paper 451 is caught by the hand 53 . P2 in FIG. 4 shows the state immediately after the end of wrapping. The leading edge of the band-wrapping paper 451 is sandwiched between the transport rollers 54 of the band-wrapping unit 5 .

Upon receiving the detection signal from the empty sensor 414 , the control unit 101 first stops driving the conveying roller 54 . As a result, the banded paper 451 sandwiched between the transport rollers 54 is allowed to be rewound. Next, the control section 101 drives the reel driving motor 412 of the reel setting section 4 in the rewinding direction of the band wrapping paper 451, as indicated by P3 in FIG. As a result, the leading edge of the wrapping paper 451 returns from the wrapping unit 5 to the reel set section 4 .

The control unit 101 stops the reel drive motor 412 when the band-wrapped paper detection sensor 423 detects light transmission. The leading end of the banded paper 451 is positioned closer to the reel 45 than the banded paper detection sensor 423 . Since the wrapping paper 451 is stored in the reel set part 4, when the operator pulls out the reel set part 4 from the banknote sorter 1 in order to replace the reel 45, the wrapping paper 451 becomes unnecessary. It is possible to prevent the wrapping paper 451 from being pulled out or the wrapping paper 451 from being cut in the middle (see P4 in FIG. 5). When the empty sensor 414 is detected, the position of the leading edge of the wrapping paper 451 is not adjusted).

The banknote sorter 1 also rewinds the band-wrapped paper 451 when conditions other than the detection of the empty sensor 414 are satisfied. Specifically, after starting the bundling process, the control unit 101 feeds out all the loose banknotes that have been inserted into the insertion unit 13 so that the insertion unit 13 is emptied, and the first to fifth stacking units 31 to 35 are When all of them are empty, the wrapping paper 451 is rewound (rewinding condition 1). This is because the bundling process is completed and the banknote sorter 1 is considered to be in a standby state. When the banknote sorter 1 is in the standby state, the operator may mistakenly pull out the reel set section 4 or the banding unit 5 .

After the end of the wrapping process, the control section 101 rewinds the wrapping paper 451 when a predetermined time (for example, 10 seconds) has passed without receiving an instruction for the next wrapping process (rewinding condition 2). This is because the bundling process is completed and the banknote sorter 1 is considered to be in a standby state. Also at this time, the operator may mistakenly pull out the reel set portion 4 or the banding unit 5 in the same manner as described above.

Further, the control unit 101 rewinds the banded paper 451 when an error occurs during execution of the banding process (rewinding condition 3). The operator may pull out the reel set part 4 or the banding unit 5 in order to clear the error.

When any one of the three rewinding conditions 1 to 3 is satisfied, the control unit 101, in the same manner as described above, keeps the bundled paper 451 until the bundled paper detection sensor 423 detects light transmission. After that, the controller 101 drives the feed motor 422 in the feed direction by a predetermined amount. Then, in response to detection of light shielding by the wrapped paper detection sensor 423 , the control section 101 stops the feed motor 422 . As a result, the leading edge of the wrapping paper 451 is closer to the wrapping unit 5 than when the wrapping paper 451 is rewound by the detection of the empty sensor 414, as indicated by P4 in FIG. The amount of feed by the feed motor 422 is appropriately set as long as the leading end of the band-wrapped paper 451 is positioned within the reel set section 4 .

When the empty sensor 414 detects, the reel 45 is replaced. On the other hand, when conditions other than the detection of the empty sensor 414 are satisfied, the banding process is resumed without performing the replacement work of the reel 45 . In this case, it is preferable that the banding process is restarted promptly. Therefore, when conditions other than the detection of the empty sensor 414 are established, the leading edge of the banded paper 451 rewound on the reel set section 4 is positioned as close to the banded unit 5 as possible. By adjusting the leading end position of the wrapping paper 451, the wrapping paper 451 can be quickly sent from the reel set section 4 to the wrapping unit 5, and the wrapping process can be restarted quickly.

On the other hand, the leading end of the banded paper 451 is positioned inside the reel set section 4 and the banded paper 451 does not straddle between the reel set section 4 and the banding unit 5 . Therefore, as shown in P4 of FIG. 5, even if the reel set section 4 and the band-wrapping unit 5 are pulled out from the banknote sorter 1, the band-wrapped paper 451 may be pulled out unnecessarily or the band-wrapped paper 451 may be cut in the middle. to prevent it from falling.

When the empty sensor 414 detects, the wrapped paper detection sensor 423 is in the light-transmissive state, and by completing the rewinding of the wrapped paper 451, the control unit 101 determines that the reel 45 has been replaced. becomes possible. In other words, the control unit 101 detects that the reel set unit 4 is pulled out and pushed in by the sensor, and that the wrapped paper detection sensor 423 switches from light transmission to light blocking due to the leading edge of the wrapped paper 451 fed from the new reel 45. Based on this, it becomes possible to determine that the reel 45 has been replaced.

(Switching the banknote sorter mode)
The banknote sorter 1 switches between a bundling mode for executing the above-described bundling processing, a deposit mode for executing deposit processing for counting bills, and a batch mode for executing batch counting processing for classifying bills into predetermined numbers. be able to.

More specifically, in the deposit process, the banknote sorter 1 feeds out the banknotes inserted into the input unit 13 one by one, and the identification unit 18 identifies and counts the banknotes. The banknote transport unit 3 transports the banknotes to the first external stacking unit 11 or the second external stacking unit 12 according to predetermined classification conditions based on the identification result. The first reversing unit 21 and the second reversing unit 22 reverse the bills as necessary, thereby aligning the front/back and top/bottom directions of the bills stacked in the first external stacking unit 11 and the second external stacking unit 12 .

In batch processing, the banknote sorter 1 feeds banknotes inserted into the input unit 13 one by one, and the identification unit 18 identifies and counts the banknotes. The banknote transport unit 3 transports predetermined banknotes to be batched to the first external stacking unit 11 and the second external stacking unit 12 based on the identification result. The first external stacking unit 11 and the second external stacking unit 12 alternately stack a designated number of banknotes. The first reversing unit 21 and the second reversing unit 22 reverse the bills as necessary, thereby aligning the front/back and top/bottom directions of the bills stacked in the first external stacking unit 11 and the second external stacking unit 12 .

As described above, the banknote sorter 1 can leave fractional banknotes in the first to fifth stacking units 31 to 35 in the bundling mode after the bundling process is completed. Fractional banknotes remaining in the first to fifth stacking units 31 to 35 are banknotes whose counting has been finalized. On the other hand, it was not possible to switch from the wrapping mode to the deposit mode or the batch mode.

On the other hand, the banknote sorter 1 is configured to be able to switch to the deposit mode or the batch mode even if fractional banknotes remain in the first to fifth stacking units 31-35. Since the banknote sorter 1 does not use the first to fifth stacking units 31 in deposit processing and batch processing, even if fractional banknotes remain in the first to fifth stacking units 31 to 35, the deposit processing and batch processing are not performed. processing can be performed.

Further, when an error occurs during execution of deposit processing or batch processing, the operator may remove the error by pulling out the sorting unit 6 forward from the bill sorting machine 1, as described above. When the organizing unit 6 is pulled out, the operator also takes out the fractional banknotes remaining in the first to fifth stacking units 31-35 from the first to fifth stacking units 31-35. After performing the resetting operation, the banknote sorter 1 performs a return process for the fractional banknotes that have been taken out. Fractional banknotes taken out from the first to fifth stacking units 31-35 are returned to the original first to fifth stacking units 31-35. By executing such return processing, it is possible to prevent the occurrence of miscalculations even when an error occurs during deposit processing or batch processing in the residual operation state.

In this way, the banknote sorter 1 can switch to the deposit mode or the batch mode and execute the deposit process or the batch process during the remaining operation. Further, after that, when the deposit mode or the batch mode is switched to the banding mode again, it becomes possible to execute the banding process in the state of the remaining operation. When returning to the bundling mode during the remaining operation, the banknotes to be bundled to be stacked in the first to fifth stacking units 31 to 35 are restricted to the same bills as those designated in the original bundling mode.

Although not shown, a lock mechanism is provided to prevent the operator from touching the banknotes stacked in the first to fifth stacking units 31 to 35 when the sorting unit 6 of the banknote sorter 1 is pulled out. may be provided. As for the locking mechanism, a door with an electromagnetic lock may be attached to each of the first to fifth stacking units 31 to 35 . Further, a door with an electromagnetic lock may be attached to the banknote handling machine 1 to cover the entirety of the first to fifth stacking units 31 to 35 . By doing this, when the sorting unit 6 is pulled out, the operator cannot touch the banknotes stacked in the first to fifth stacking units 31 to 35, so that the above-described return processing for canceling the error can be performed. can be omitted.

(Re-identification of damaged banknotes)
The accuracy of the determination of fitness by the identification unit 18 varies depending on factors such as the ink thickness and material of the banknote, and depending on the direction of the front and back and the top and bottom. Therefore, in order to increase the accuracy of the fitness determination of the recognition unit 18 and reduce the number of banknotes that are determined as damaged banknotes, the banknote sorter 1 aligns the orientation of the banknotes identified as damaged banknotes, and then performs the check again. , is configured to identify.

FIG. 6 is a diagram for explaining the conveying route of damaged banknotes in the banding mode. As described above, bills inserted into the insertion unit 13 are identified by the identification unit 18 . As a result of identification, banknotes to be banded other than damaged banknotes pass through the first reversing section 21 and the second reversing section 22 and are stacked in a predetermined stacking section 3a among the first to fifth stacking sections 31 to 35. be done. On the other hand, banknotes identified as damaged banknotes are stacked in the stacking unit 3b, which is different from the stacking unit 3a, out of the first to fifth stacking units 31-35. Banknotes stacked in the stacking unit 3b are subject to re-identification. The first reversing unit 21 and the second reversing unit 22 reverse banknotes identified as damaged banknotes and align both the front and back sides and the top and bottom before stacking them in the stacking unit 3b for re-identification. At this time, the first reversing unit 21 and the second reversing unit 22 align the banknotes in the direction with the highest accuracy of fitness determination.

After all the banknotes inserted into the insertion unit 13 are fed out, the banknote transport unit 36 transports the banknotes stacked in the re-identification stacking unit 3 b to the return unit 16 . The operator takes out the banknotes from the return unit 16 and reinserts them into the input unit 13 (see the dashed arrow in FIG. 6) to re-identify the banknotes. Since the bills are oriented in the same direction, the identification accuracy is enhanced. Fewer banknotes are identified as spoiled banknotes. As a result of re-identification by the recognition unit 18, banknotes that are not determined to be damaged banknotes are transported to a predetermined stacking unit 3a and stacked there. On the other hand, as a result of the re-identification by the recognition unit 18, banknotes that are again determined to be damaged banknotes are dispensed to the reject unit 14 as indicated by the two-dot chain line in FIG.

Instead of stacking the banknotes identified as damaged banknotes in the stacking unit, as indicated by the dashed line in FIG. , the first external stacking unit 11 or the second external stacking unit 12 . In this case, the operator reinserts the banknotes stacked in the first external stacking unit 11 or the second external stacking unit 12 into the input unit 13 .

In addition, although not shown in the drawings, a transport path is provided inside the banknote sorter 1 through which banknotes can be sent from the stacking unit 3b to the identification unit 18, so that banknotes can be automatically re-identified. may

Further, the number of times of re-identification is not limited to two, and may be three or more. When identification is performed three times or more, the orientation of aligning the front and back of the bill and the top and bottom may be changed each time identification is performed.

The banknote sorter 1 may perform re-identification of banknotes identified as rejected banknotes instead of banknotes identified as damaged banknotes by the above-described procedure.

(Configuration example of banknote handling machine)
The technique disclosed here is not limited to being applied to the banknote sorter 1 shown in FIG. 1 and the like. FIG. 7 shows a bundled banknote processing machine 200 as an example of a paper sheet processing apparatus to which the technology disclosed herein can be applied. Although not shown, the bundled banknote processing machine 200 constitutes a part of a so-called teller machine.

The bundled banknote processing machine 200 prepares a bundled banknote by bundling a predetermined number of banknotes (for example, 100) into a single bundled banknote, stores the bundled banknotes in the device, and stores the bundled banknotes of a specified denomination and number of bundles. to the outside of the device.

The banded banknote handling machine 200 includes a banding mechanism 201 , a first transport mechanism 202 , an elevating mechanism 203 , a second transport mechanism 204 and five stackers 205 . A banding unit 209 is configured by the banding mechanism 201 and the first transport mechanism 202 .

The bundling mechanism 201 is provided in front of a transport section 115 that transports a bundle of loose banknotes. The bundling mechanism 201 creates a bundled banknote by bundling a bundle of loose banknotes.

The first conveying mechanism 202 is provided in front of the banding mechanism 201 . The first transport mechanism 202 has a pair of upper and lower belt units extending in the front-rear direction. The first conveying mechanism 202 conveys the bundled banknote to the lifting mechanism 203 in front by sandwiching the bundled banknote between a pair of upper and lower belt units.

The elevating mechanism 203 includes an elevating space 203a that extends vertically along the front surface of the banded banknote processing machine 200, and a lift 203b that moves up and down in the elevating space 203a with the banded banknotes placed thereon. The lifting space 203a is connected to the deposit/withdrawal port 206 at its upper portion, and is connected to the discharge port 207 at its lower portion. The lift 203b moves up and down between the stand-by position at the outlet 207 and the upper limit position where the first transport mechanism 202 and the deposit/withdrawal port 206 are located.

The lift 203b includes a base and a mounting plate stacked on the base and tiltable with respect to the base. When the stacking plate tilts while the lift 203 b carrying the wrapped banknote is at the standby position, the wrapped banknote slides down from the stacking plate and is ejected from the outlet 207 . Also, the lift 203 b receives the bundled bill from the first transport mechanism 202 and conveys the received bundled bill to the second transport mechanism 204 . Further, the lift 203b receives the bundled banknotes from the second transport mechanism 204 and conveys the received bundled banknotes to the positions of the deposit/withdrawal port 206 and the dispensing port 207 .

The second conveying mechanism 204 is configured by a belt that is stretched between a pair of rollers that are spaced apart in the front-rear direction. The belt can run both clockwise and counterclockwise in FIG. A plurality of projections are formed on the belt at regular intervals. As the protrusions move back and forth as the belt rotates, the bundled banknotes are pushed by the protrusions and moved on the bundle conveying path 204b provided below the belt. In addition, the front end of the belt projecting into the lifting space 203a is configured to be retractable from the lifting space 203a.

The stacker 205 is used to store the bundled bills generated by the bundling mechanism 201 by denomination. For example, denominations such as 10,000 yen, 1,000 yen, and 5,000 yen are assigned to each of the five stackers 205 . In the stacker 205, the bundled banknotes are stored so as to be stacked vertically. An elevating stage 205a is provided in the stacker 205 to elevate the stored banded banknotes.

The bundle conveying path 204b is provided with an entrance and exit that is opened and closed by a shutter above each stacker 205 . When the bundled bills are stored from the bundle transport path 204b to the stacker 205 or when the bundled bills are delivered from the stacker 205 to the bundle transport path 204b, the shutter is opened and the entrance and exit are opened. Bundled banknotes are put into and taken out of the stacker 205 through the doorway.

A reel set section 208 is arranged below the banding unit 209 . The banding unit 209 and the reel set section 208 overlap vertically. Inside the reel setting section 208, a reel 208a of banded paper to be supplied to the banded unit 209 is set. The banded paper pulled out from the reel 208 a is supplied to the banded paper unit 209 . Although illustration is omitted, the band-wrapped paper straddles between the band-wrapped unit 209 and the reel set section 208 .

The reel set unit 208 is configured to be able to be pulled forward from the banded banknote processing machine 200 together with a part of the front housing of the banded banknote processing machine 200, as indicated by a dashed line in FIG. When mounting the reel 208 a of the banded paper to the reel set unit 208 , the operator pulls out the reel set unit 208 to the front of the banded banknote processing machine 200 . In the bundled banknote processing machine 200 , the bundled unit 209 and the reel set section 208 constitute a paper sheet bundle mechanism 210 .

In this banded banknote processing machine 200 as well, the banded paper straddles between the reel set section 208 and the banded unit 209 which overlap in the vertical direction. If the reel set part 208 and the banding unit 209 move relative to each other while the banded paper is straddling them, the banded paper may be pulled out from the reel 208a unnecessarily or the banded paper may be cut in the middle. Therefore, the bundled banknote processing machine 200 also instructs the next bundling process after completing the bundling process under a predetermined condition, that is, when the replacement detection sensor (empty sensor) detects that the reel 208a should be replaced. It is configured to rewind the banded paper to the reel set unit 208 when a predetermined time has passed without being received (rewinding condition 2) and when an error occurs during execution of the banding process (rewinding condition 3). ing. The procedure for rewinding the wrapping paper may be performed in the same manner as described above (see FIGS. 4 and 5). By rewinding the banded paper until the tip of the banded paper is positioned within the reel set portion 208a, even if the reel set portion 208 and the banded unit 209 move relative to each other, the banded paper may not be pulled out from the reel 208a or the banded paper is prevented from disconnecting in the middle.

It should be noted that the technology disclosed herein can be widely applied not only to devices that process bills, but also to devices that process paper sheets including valuable media such as checks and gift certificates.
