Description

  The present invention relates to a paper sheet handling apparatus that can accept a normal paper sheet without returning it to the insertion slot when it is a normal note even if the paper sheet inserted from the insertion slot is a deformed paper sheet. About.

  2. Description of the Related Art Conventionally, for example, there is a bill storage / delivery device of a bill deposit / withdrawal unit mounted on an ATM (automated telling machine) used in financial institutions and the like. Also, a paper sheet feeding device is mounted on a ticket vending machine installed in a station or the like.

  In the banknote insertion slot of such a banknote depositing / dispensing unit, a single banknote or a stack of stacked banknotes is inserted in a substantially vertical direction in a horizontally long state, but also in a horizontally long state, Some are inserted in the direction.

  As a paper sheet storage device that inserts a plurality of stacked banknote bundles horizontally into the insertion slot in a horizontal state and accepts the banknotes, a plurality of paper sheets are collectively sandwiched between conveyance belts, A paper sheet storage device has been proposed which aims to align and temporarily hold and align the paper sheets stored in the storage chamber by pushing the aligned banknote bundle into the storage chamber. Yes. (For example, refer to Patent Document 1.)

  In addition, such a paper sheet storage device normally feeds paper sheets stored in the storage room one by one from the bottom of the storage room and transports them by a transport path, and stores a large amount of the paper sheets. And a plurality of large-sized stacking containers equipped with a stacking mechanism for stacking.

  As an example of such a large stacking container, during the stacking operation of feeding the transported paper sheet to the stacking storage section (large stacking container), the sheet stacking is performed by the push plate mechanism section based on the signal from the sheet upper end detection means. There has been proposed a device that controls the operation of the pressing plate so that the space is enlarged and there is no space beyond a predetermined space between the stacked paper sheets. (For example, see Patent Document 2.)

  By the way, paper sheets (hereinafter referred to as banknotes) in each country are not only different in size, but also when walking with a banknote in their country, in the country where people have a habit of carrying them in their wallets, the banknotes are bare. There are various countries where it is customary to bend and keep it in your pocket.

  When depositing banknotes that are folded naked and carried in pockets in an ATM, the depositor extends the banknotes and inserts them into the ATM banknote insertion slot.

  Also, in the case of banknotes put in a wallet, if the wallet is a double-folded wallet, the banknotes taken out from the wallet are bent and wrinkled. In this case, the curl of the banknote bundle is corrected to the extent that it enters the banknote insertion slot, and the banknote is inserted into the ATM banknote insertion slot.

  9 (a) to 9 (d) show an ATM banknote take-in unit and banknote delivery similar to the configuration of Patent Document 1 when accepting a banknote with such a fold or a banknote with a bent hook. It is a figure which shows simply the processing operation of a unit.

  9 (a) to 9 (d) will be described in order from the top. First, FIG. 9 (a) shows a two-layered structure in which the folds are extended to the height of the insertion slot 2 at the insertion slot 2 of the bill taking-in unit 1. The state where the bill 3 is inserted is shown. The arrow a indicates the insertion direction of the banknote 3. Moreover, the longitudinal direction of the banknote 3 is the depth direction of the figure.

  A transmissive optical sensor 4 is arranged in the vicinity of the insertion slot 2. The transmission optical sensor 4 detects the bill 3 inserted into the insertion slot 2. In the bill taking-in unit 1, a clamp belt 5 and a transport belt 6 are arranged above and below a space formed slightly higher than the height of the insertion slot 2.

  Moreover, the clamp position detection sensor 7 is arrange | positioned below at the rear-end part of the banknote taking-in unit 1, and the rotation support shaft 9 of the hook 8 is arrange | positioned above. Further, the back end portion 5 a extending in the direction of the bill feeding unit 10 of the clamp belt 5 disposed at the upper part enters the bill feeding unit 10.

  The other banknote feeding unit 10 has a banknote receiving space 11 having a height substantially the same as the height of the space formed by the clamp belt 5 and the transport belt 6 of the banknote taking-in unit 1 at the upper part connected to the banknote taking-in unit 1. Is formed.

  An upper guide member 12 and a lower guide member 13 are arranged above and below the bill receiving space 11, respectively. The end of the upper guide 12 in the direction of the banknote taking unit 1 overlaps the above-described inner end 5 a of the clamp belt 5 of the banknote taking-in unit 1. Further, below the bill feeding unit 10, a feeding roller 14 and a feeding roller pair 15 are arranged.

  In FIG. 9 (a), when the transmission optical sensor 4 detects that the bill 3 has been inserted from the insertion slot 2, the clamp belt 5 descends downward as shown by the arrow b, and the bill 3 is pushed to a predetermined level. It stops when it is clamped together with the conveyor belt 6 by pressure. The clamp position detection sensor 7 detects that the clamp belt 5 has stopped.

  Here, as shown in FIG. 9B, the drive roller 16 on which the clamp belt 5 is stretched rotates in the clockwise direction as indicated by an arrow c, and the drive roller on which the transport belt 6 is stretched. 17 rotates counterclockwise as indicated by an arrow d.

  That is, the lower conveying surface 5b of the clamp belt 5 circulates and moves in the direction of the bill feeding unit 10 as indicated by the arrow e, and the upper conveying surface 6a of the conveying belt 6 circulates and moves in the direction of the bill feeding unit 10 as indicated by the arrow f. To do. Thereby, the banknote 3 pressed and clamped between the clamp belt 5 and the transport belt 6 is transported to the banknote receiving space 11 of the banknote feeding unit 10, and the banknote 3 is delivered from the banknote taking-in unit 1 to the banknote feeding unit 10.

  Following the above, as shown in FIG. 9 (c), the clamp belt 5 is raised to the home position shown in FIG. 9 (a) as indicated by the arrow g, and the pressure on the banknote 3 is released. The banknote 3 whose pressure has been released returns to the state in which the folds have been recovered to the height at which it was inserted into the insertion slot 2.

  When the banknote 3 has a folding fold or a bent fold, the banknote 3 is often skewed during conveyance. If the degree of skew is large, the rear end of the banknote 3 delivered to the banknote receiving space 11 often protrudes toward the banknote taking-in unit 1 side.

  Therefore, assuming such a case, when the banknote 3 is delivered to the banknote receiving space 11, the hook 8 is rotated clockwise from the home position indicated by the broken line by the rotation support shaft 9 as indicated by the arrow h. The rear end of the banknote 3 that may be driven and moved out to the banknote taking-in unit 1 side is hit.

  If the rear end of the banknote 3 has jumped out to the banknote taking-in unit 1 side, the rear end is impacted by hitting with the hook 8, and the banknote 3 jumps into the banknote receiving space 11 by reaction of the impact. Delivery of the banknote 3 to the banknote receiving space 11 is completed.

  Subsequently, as shown in FIG. 9 (d), the upper guide member 12 and the lower guide member 13 start to descend simultaneously from the position of the home position indicated by the broken line as indicated by arrows i and j, respectively. The lower guide member 13 stops at a position where the surface on which the bill 3 is placed coincides with the upper peripheral surface of the lower roller of the feeding roller pair 15.

  One upper guide member 12 further descends and stops when the bill 3 is pressed against the feeding roller 14 with a predetermined pressing force. The feeding roller 14 is slidably contacted with the bottom surface of the lowermost banknote 3 to rotate, and the lowermost one banknote 3 is fed toward the feeding roller pair 15. The supply roller pair 15 takes over the supply to the banknote 3 and discharges the banknote 3 toward the conveyance path outside the figure.

  By the way, as described above, in the paper sheet handling apparatus that handles and conveys one to a bundle of banknotes, when handling a deformed sheet or bundle of banknotes with folds or bent folds, the paper sheets In the take-in unit, the clamp is lowered to sandwich the banknote, thereby suppressing the deformation of the banknote and stabilizing the conveyance.

  However, when handing over the deformed banknotes to the paper sheet feeding unit, the banknotes are handed over to the banknote receiving part of the wide banknote receiving space up and down, so that there is a problem that the state in which the deformation of the banknotes is suppressed cannot be maintained. .

  For this reason, when a bill is lowered to the feeding portion, the bill is pressed into the lower guide portion by the upper guide portion. However, when the banknote deformed in this way is pressed down, the deformed banknote is likely to be further deformed, for example, such that the corner portion is folded inward.

  In this way, when the banknote is largely deformed, skewing or feeding failure is caused when the bill is fed from the feeding unit to the conveyance path. Jam occurs when the feeding failure occurs. When a jam occurs, the device stops and a maintenance worker comes and waits for the customer to recover from the feeding failure.

  If the skew is greater than the allowable amount, a conveyance failure is caused on the conveyance path. Even if the conveyance failure does not occur on the conveyance path, if the skew is equal to or larger than the allowable amount, the discrimination unit determines that the banknote is defective and is often returned to the banknote insertion slot.

  Although it is natural to return items that are heavily soiled or non-genuine banknotes, if they are regular banknotes, they will be returned regardless of whether they have been inserted into the banknote insertion slot. As a result, customers who want to make deposits feel uncomfortable.

  There is a high possibility that a customer who has been waiting in a jam or once feels uncomfortable will not use the ATM again. If it becomes so, the availability factor of ATM will fall. Moreover, if the ATM is returned without accepting a regular bill, the acceptance rate of the bill is deteriorated.

  The present invention solves the above-described conventional problems, and is a normal ticket inserted from a paper sheet insertion slot. An object of the present invention is to provide a paper sheet handling apparatus that can take in as usual without returning to the factory.

  In order to solve the above problems, a paper sheet handling apparatus according to the present invention conveys in a horizontal direction while pressing a paper sheet inserted from the insertion port in the thickness direction. A horizontal conveyance unit, a vertical conveyance unit that receives the paper sheet conveyed in the horizontal direction from the horizontal conveyance unit, and conveys the paper sheet in a vertical direction while pressing the paper sheet in the thickness direction, and the vertical conveyance unit At least a feeding section that feeds the paper sheet transported by a paper transport path disposed outside the vertical transport section, and the horizontal transport section has a height of the pressed paper sheet. A height detection unit that detects a height of the sheet detected from the horizontal conveyance unit by adding a predetermined amount to the height detected by the height detection unit. Configured to set to initial height.

  The horizontal transport unit is configured, for example, to release the pressing of the paper sheet after transporting the paper sheet to the vertical transport unit, and further, for example, release the pressing of the paper sheet Then, it is comprised so that it may have an extrusion part which extrudes the said paper sheets to the said vertical conveyance part.

  In the paper sheet handling apparatus, the predetermined amount is preferably set to be 2 mm or more and 13 mm or less, for example.

  According to the paper sheet handling apparatus of the present invention, the vertical transport unit receives the paper sheet at a standby initial height that is higher by a predetermined amount than the height of the paper sheet transported while being pressed by the horizontal transport unit. Even if a single sheet inserted from the insertion slot or a stack of stacked sheets is a deformed sheet with creases or creases, the pressure from the horizontal transport unit is released. The deformed paper sheets do not greatly return to the original deformation amount, so that the deformed banknotes are pressed in a normal state without causing further deformation by pressing of the vertical transport unit, and the paper sheets are transported by the feeding unit. It goes out to the road.

  Therefore, even deformed paper sheets with creases and bent folds can be accepted as usual without being returned to the insertion slot, which does not cause discomfort to the customer. This has the effect of improving the acceptance rate of paper sheets.

A bill conveyance path from the bill feeding unit 26 to the discriminator 30 is formed.

  Further, the upper module 20 passes from the rear side surface of the discriminator 30 between the lower surface of the normal ticket primary storage unit 27 and the bottom of the upper module 20 main body and between the bottom surface of the reject box 29c and the bottom of the upper module 20 main body. An upper conveyance path 33 is formed between the rear inner wall of the main body.

  On the one hand, the upper conveyance path 33 transfers the banknotes to the lower conveyance path 34 arranged at the uppermost part of the lower module 21 and, on the other hand, branches at two locations by the switching gate 35 in the upper module 20. It cooperates with the conveyance from the discriminator 30 to the normal ticket primary reservation part 27 or the non-performing ticket primary reservation part 28, and the conveyance from the discrimination machine 30 to each reject box 29 by the conveyance path to be performed.

  The lower module 21 includes four recycling cassettes 36 (36a, 36b, 36c, and 36d) as large-sized storage containers below the lower conveyance path 34. The banknote bundle 18 inserted into the deposit / withdrawal port 24 of the upper module 20 is conveyed from the banknote feeding unit 26 to the above-described parts through the discriminator 30.

  The present invention relates to the banknote taking-in unit 25 and the banknote feeding unit 26, and is not related to other hardware configuration requirements, so the description of the detailed configuration of the paper sheet handling device 19 main body is omitted above. To do.

  FIG. 2 is a circuit configuration diagram of the paper sheet handling apparatus 19. The banknote capturing unit 25 has a configuration including a sensor group 37, a motor group 38, and a solenoid group 39. The sensor group 37 includes a transmission optical sensor, a clamp position detection sensor, and the like, which will be described later.

  The motor group 38 includes a motor that is a power source for moving a clamp belt, which will be described later, of the bill taking-in unit 25 up and down, a drive motor that circulates and moves the clamp belt and a conveyance belt stretched below the clamp belt. The solenoid group 39 includes solenoids that rotationally drive a pivot support shaft of a hook that will be described later.

  The upper module 20 operates by controlling a printed circuit board (PCB) 40. Motor groups 41 and 38, a DC motor 42, sensor groups 43 and 37, solenoid groups 44 and 39, and a discriminator 30 are connected to the printed circuit board 40. In this way, the bill taking-in unit 25 is controlled by the upper module 20.

  The motor group 41 is composed of, for example, a plurality of stepping motors. Although the stepping motor is not particularly described in FIG. 1, each stage on which the banknote bundle 18 is placed in the banknote feeding unit 26, the normal ticket primary storage section 27, the non-permitted primary storage section 28, the reject box 29, etc. Each pusher is driven to move.

  The DC motor 42 is a power source for transporting banknotes fed out from the banknote feeding unit 26.

  The sensor group 43 includes a plurality of sensors installed in each conveyance path for bill detection, a plurality of sensors installed in the bill feeding unit 26, and a plurality of sensors installed in the normal ticket primary storage unit 27 and the non-permitted ticket primary storage unit 28. Consists of sensors and the like.

  The solenoid group 44 includes a solenoid for switching the state of the switching claw of the switching gate 35 on each transport path.

  On the printed circuit board 40, a CPU 45 that controls the entire upper module 20 and a ROM 47, a RAM 48, a sensor driving unit 49, a motor driving unit 51, and a solenoid driving unit 52 connected to the CPU 45 via a printing circuit 46 are provided. , An interface (I / F) 53 is mounted.

  The ROM 47 stores programs executed by the CPU 45 and various control data. The RAM 48 is used as a work area in which the CPU 45 temporarily stores data being calculated and calculation result data.

  The sensor driving unit 49 drives the sensors constituting the sensor groups 37 and 43. The motor drive unit 51 drives the stepping motor and the DC motor 42 that constitute the motor groups 38 and 41.

  The solenoid drive unit 52 individually drives the solenoids constituting the solenoid groups 39 and 44. An interface (I / F) 53 transmits and receives signals to and from the discriminator 30 and communicates with the lower module 21.

  The lower module 21 operates by controlling a printed circuit board (PCB) (not shown). The printed circuit board is connected to a motor group that drives each part of the lower module 21 shown in FIG. 1, a solenoid group, and a sensor group that detects the position of the banknote bundle 18.

In the above configuration, the operations of the bill taking-in unit 25 and the bill feeding unit 26 in this example will be described below.
FIG. 3A is a flowchart for explaining the operations of the banknote taking-in unit 25 and the banknote feeding unit 26 operating under the control executed by the CPU 45, and FIGS. 3B to 3E are operations at that time. It is a figure which shows a state.

  The configurations shown in FIGS. 3B to 3E are the same as the configurations shown in FIGS. 9A to 9D except that the processing operations are different. Therefore, in FIGS. 3B to 3E, the numbers of the banknote taking-in unit 25, the banknote feeding unit 26, the deposit / withdrawal port 24, and the banknote bundle 18 are shown in FIGS. 9A to 9D. The same components as those shown in FIG. 9 are denoted by the same reference numerals as in FIGS.

  Moreover, since the arrangement | positioning relationship of each component of the banknote taking-in unit 25 and the banknote feeding unit 26 and the description of the name of each component are as having demonstrated in FIG. 9, description here is abbreviate | omitted and description of the following operations | movements. Only the operation will be described with reference to the related components.

  In FIG. 3 (a), first, for example, a two-layered banknote bundle 18 with a fold extending to the height of the deposit / withdrawal port 24 is deposited into the deposit / withdrawal port 24 of the banknote taking-in unit 25 (step S1). . Subsequently, the bill bundle 18 inserted from the deposit / withdrawal port 24 is detected by the transmissive optical sensor 4 arranged in the vicinity of the deposit / withdrawal port 24 (step S2).

  FIG. 3B shows the state at this time. An arrow a indicates the insertion direction of the banknote bundle 18. Further, the longitudinal direction of the banknote bundle 18 is the depth direction in the figure. Here, when the banknote bundle 18 is detected, the clamp belt 5 disposed above the space for taking in the banknote bundle 18 is lowered (step S3). The arrow b in FIG. 3B indicates that the clamp belt 5 is lowered.

  The clamp belt 5 stops when the banknote bundle 18 is clamped together with the transport belt 6 with a predetermined pressing force. The clamp position detection sensor 7 detects a position where the clamp belt 5 is stopped. Based on this detection signal, the CPU 45 calculates the number of banknotes of the banknote bundle 18 deposited in the deposit / withdrawal port 24 (step S4).

  Next, the CPU 45 lowers the upper guide member 12 to a predetermined position, which will be described later in detail, and contracts the bill receiving space 11 of the bill feeding unit 26 (step S5). In FIG. 3 (c), the upper guide member 12 lowered from the home position indicated by the broken line to a predetermined position, and the bill receiving space 11 whose top and bottom are reduced from the initial receiving space shown in FIG. Show.

  Then, CPU45 conveys the banknote bundle 18 (step S6). In this process, as shown in FIG. 3 (c), the CPU 45 rotationally drives the driving roller 16 in the clockwise direction indicated by the arrow c, and rotationally drives the driving roller 17 in the counterclockwise direction indicated by the arrow d. .

  Thereby, the lower conveyance surface 5b of the clamp belt 5 circulates and moves in the direction of the bill feeding unit 10 indicated by the arrow e, and the upper conveyance surface 6a of the conveyance belt 6 circulates and moves in the direction of the bill feeding unit 10 indicated by the arrow f.

  Thereby, the banknote bundle 18 pressed and clamped between the clamp belt 5 and the transport belt 6 is conveyed to the reduced banknote receiving space 11 of the banknote feeding unit 26, and the banknote bundle 18 is transferred from the banknote taking-in unit 25 to the banknote feeding unit 26. Delivered (step S7).

  Subsequently, the clamp belt 5 is raised to a position where it overlaps with the upper guide member 12 (step S8). That is, as shown by the arrow g in FIG. 3 (d), the clamp belt 5 rises to a position where it overlaps the upper guide member 12, and the pressure on the banknote bundle 18 is released.

  However, since the banknote receiving space 11 is reduced and the vertical interval is narrowed, the banknote bundle 18 released from being pressed can be broken up to the height when it is inserted into the deposit / withdrawal port 24 to recover the wrinkles. Rather, it is restrained to a lower height.

  Here, the hook 8 is rotationally driven (step S9). That is, as shown in FIG. 3 (d), the hook 8 is rotated clockwise from the home position position indicated by the broken line by the rotation support shaft 9 as indicated by the arrow h, and moved toward the banknote taking-in unit 25 side. Strike the rear end of the banknote bundle 18 that may be popping out.

  If the rear end of the banknote bundle 18 has jumped out to the banknote taking-in unit 25 side, the rear end is impacted by hitting with the hook 8, and the banknote bundle 18 is moved into the banknote receiving space 11 by reaction of the impact. Dive and delivery of the banknote bundle 18 between the banknote taking-in unit 25 and the banknote receiving space 11 is completed.

  Subsequently, the upper guide member 12 and the lower guide member 13 are simultaneously lowered (step S10). In this processing operation, as shown in FIG. 3 (e), the upper guide member 12 is from the position indicated by the broken line overlapping the clamp belt 5, and the lower guide member 13 is from the position of the home position indicated by the broken line. As shown by arrows i and j, they descend simultaneously.

  The lower guide member 13 stops at a position where the surface on which the banknote bundle 18 is placed coincides with the upper peripheral surface of the lower roller of the feeding roller pair 15. The upper guide member 12 further descends and stops when the banknote bundle 18 is pressed against the feeding roller 14 with a predetermined pressing force.

  As described above, even if the banknote bundle 18 is released from the press, the deformed wrinkles cannot be recovered to the height when the banknote bundle 18 is inserted into the deposit / withdrawal port 24, and the banknote bundle 18 is restrained to a lower height state. Therefore, when the upper guide member 12 is further lowered and presses the banknote bundle 18, the deformed wrinkles of the banknote bundle 18 are corrected to a horizontal state without causing any further inconvenient deformation.

  The CPU 45 drives the feeding roller 14 and the feeding roller pair 15 to feed out the banknote bundle 18 (step S11). In this processing operation, the feeding roller 14 rotates in sliding contact with the bottom surface of the banknote bundle 18 and feeds the lowest banknote toward the feeding roller pair 15.

  The feeding roller pair 15 takes over the feeding of banknotes and discharges the banknotes toward a transport path (not shown) (a transport path communicating with the discriminator 30 in FIG. 1).

  4 (a) and 4 (b) are diagrams illustrating basic operations of deposit acceptance and banknote delivery in the processing operation described above. FIG. 4 (a) shows a state in which the banknote bundle 18 is deposited into the deposit / withdrawal port 24 formed by inserting the banknote bundle 18 (18a, 18b, 18c) into the deposit / withdrawal slot 23 formed on the wall 22. Shows the state.

  The banknote bundle 18a shows a state when inserted almost at the center of the deposit / withdrawal port 24, the banknote bundle 18b shows a state when inserted side by side to the right side of the deposit / withdrawal port 24, and the banknote bundle 18c The state when it is inserted to the left of the deposit / withdrawal port 24 is shown.

  FIG. 4B shows a bill receiving space 11 based on the time when the clamp belt 5 descends and presses and stops the bill bundle 18 at the time of bill delivery between the bill taking-in unit 25 and the bill feeding unit 26. The upper space 11a formed is shown.

  The upper space 11a is a space having an upper and lower height Y formed by a plane on which the lower conveyance surface 5b of the clamp belt 5 that is stopped is located and a bill pressing surface 12a of the upper guide member 12. In this example, as shown in FIG. 3C, the upper guide member 12 descends according to the number of banknotes in the banknote bundle 18 to form an upper space 11a having a predetermined height Y.

  In this example, the value of the height Y of the upper space 11a is 2 mm to 12 mm, preferably 10 mm. The reason for obtaining such a conclusion will be described below. First, 10 banknotes having the same degree of bending or bending deformation are prepared. Then, 10 sheets are inserted into the deposit / withdrawal port 24.

  The reason why the number of banknotes inserted in this case is 10 is that, first, the dimensions of the deposit / withdrawal port 24 are almost determined by international standards. Is set to

  Usually, there are almost no cases where new tickets are deposited, and banknotes in circulation are deposited. Since the banknotes in circulation are more bulky than the new banknotes, for example, about 150 sheets is the appropriate maximum number. When the number of banknotes in the banknote bundle is large, there is no large space in the upper space 11a of the banknote receiving space 11, so that there is no large return of the deformed bag.

  However, when two or more deformed banknotes are handed over to the normal height banknote receiving space of the paper sheet feeding unit, a wide upper space is created, so that it is not possible to keep the banknote from being deformed. As described above, when the upper guide member and the lower guide member descend and press the bill, abnormal deformation occurs and a problem occurs in feeding.

  Therefore, in order to investigate how large the upper space 11a should be, the upper space 11a can be set variously depending on whether the upper space 11a is narrow or wide, that is, the upper space from the minimum narrowness to the maximum width. It is better that fewer deformed banknotes are inserted into the deposit / withdrawal port 24 so that 11a can be set. That said, one or two is too little. This is the reason why the number of inserted bills is 10.

  FIG. 5 shows that the bills deformed as described above are inserted into the deposit / withdrawal port 24 every ten times in various ways by changing the upper and lower widths Y of the upper space 11a in four ways and fed out from the feeding roller pair 15. It is a figure which shows the frequency distribution obtained by investigating the skewing degree of a banknote, and the frequency at which the skewed banknote appears corresponding to every position inserted in the deposit / withdrawal port.

  The graph of FIG. 5 shows the state in which the upper guide member 12 is placed at the home position from top to bottom, that is, 10 inserted banknotes and the maximum upper space 11a is 25.5 mm (actually narrow by 10 banknotes). In the following, the upper guide member 12 is lowered, and the upper space 11a for 10 inserted banknotes is set to 15 mm, set to 10 mm, set to 5 mm, set to 3 mm, respectively. Show.

  In the bar graph showing the distribution of the appearance frequency of the skewed number of sheets, the bar graph shown by double hatching shows the case of the banknote bundle 18 a shown in FIG. 4A inserted from substantially the center of the deposit / withdrawal port 24.

  Moreover, the bar graph of the right upward hatching shows the case of the banknote bundle 18b inserted to the right of the deposit / withdrawal port 24, and the bar chart of the left upward hatching of the banknote bundle 18c inserted to the left of the deposit / withdrawal port 24 is shown. Shows the case.

  Each bar graph has a skew degree of “−2 ° to + 2 °” at the center, and skews of “+ 7 ° to + 6 °”, “+ 5 ° to + 3 °”, and “+ 8 ° to the right of the bar graph. The above are shown, and those with skew degrees of “−5 ° to −3 °”, “−7 ° to −6 °”, and “−8 ° or more” are shown to the left of the center.

  Banknotes with a skew degree of less than ± 8 ° are banknotes that have a skew tolerance that is less likely to cause problems during transport along the transport path, and banknotes with a skew degree of ± 8 ° or more have problems during transport through the transport path. A banknote that has a very high possibility of waking up, and a banknote that exceeds a certain degree of skew becomes a banknote that is returned to the customer via the non-ticket primary holding unit 28.

  As seen from the graph of FIG. 5, when the upper space 11a is 25.5 mm and 15 mm, the frequency of banknotes having a skewness of ± 8 ° or more is high. In other words, the deposit acceptance rate becomes worse. On the other hand, when the upper space 11a is 10 mm or less, it is found that the frequency with which banknotes with a skewing degree of ± 8 ° or more are expressed is reduced. That is, the deposit acceptance rate is improved.

  The frequency with which the banknote having the skewness of ± 8 ° or more is increased is not limited to whether the banknote is inserted from the center of the deposit / withdrawal port 24 or is shifted to the left or right, regardless of whether the banknote is inserted to the left or right. It is found that the expression frequency is high when the height is 15 mm or more, and the expression frequency is low when the upper space 11a is 10 mm or less.

  Thus, it has been found that the factor causing skew in the banknote is the size of the upper space 11a. Here, from another point of view, it was decided to conduct an experiment of depositing, delivering, and paying out banknotes to examine skewing.

  FIG. 6A is a diagram showing that when the banknote bundle 18 is delivered from the banknote taking-in unit 25 to the banknote feeding unit 26, the rear end of the banknote stops at a different position than in the case, and FIG. FIG. 6 is a view in which a banknote bundle 18 is caused to enter the banknote receiving space 11 of the banknote feeding unit 26 by hitting the rear end portion of the banknote with the hook 8.

  In this experiment, the value of the empty space Y in the upper space 11a was set to three types of 10 mm, 5 mm, and 3 mm, and the skews in these setting states were respectively examined.

  In addition, when the value of the space interval Y is 10 mm, 5 mm, and 3 mm, observation is performed separately when the rear end portion of the banknote bundle 18 stops at the positions a, b, c, and d. It was to be. When the rear end portion of the banknote bundle 18 is at the position c or d, since the rear end portion of the banknote bundle 18 protrudes to the banknote feeding unit 26 side, the banknote bundle is pushed by the hook 8 as shown in FIG. The rear end of 18 is hit.

  6 (a) and 6 (b) show the abutting wall 54 that is not shown so far. The abutting wall 54 enters the banknote receiving space 11 as shown by an arrow k when the rear end portion of the banknote bundle 18 is hit by the hook 8 as shown in FIG. It is provided so as not to jump out from between the upper guide member 12 and the lower guide member 13.

  FIGS. 7A to 7E are views for explaining the relationship between the position of the rear end portion of the banknote bundle and the skew of the banknote bundle during delivery of the banknote bundle 18 between the banknote taking-in unit 25 and the banknote feeding unit 26. FIG. . Fig.7 (a) has shown the state of the banknote bundle 18 in the banknote receiving space 11 when the banknote bundle rear-end part shown to Fig.6 (a) exists in the position a.

  Since the position “a” at the rear end of the banknote bundle enters the banknote receiving space 11, the distance m between the front end of the banknote bundle 18 and the abutting wall 54 is narrower than the distance n in FIG. FIG. 7B shows a state in which the upper guide member 12 and the lower guide member 13 are lowered to the position shown in FIG. 3E and the feeding roller 14 starts feeding the banknote bundle 18. In this case, the skew is hardly expressed.

  FIG.7 (c) has shown the state of the banknote bundle 18 in the banknote receiving space 11 when the rear-end part of banknote bundle exists in the position d in Fig.6 (a). Since the position d of the bill rear end protrudes out of the bill receiving space 11, the distance n between the tip of the bill bundle 18 and the abutting wall 54 is relatively wide as the distance m in FIG. .

  In FIG. 7D, when the rear end of the banknote bundle is struck by the hook 8, the banknotes 18 are largely skewed because the struck recoil is offset, and the corner protruding forward strikes the butting wall 54 and stops. doing. In this case, in this state, the upper guide member 12 and the lower guide member 13 are lowered to the position shown in FIG.

  Then, as shown in FIG. 7 (e), when the feeding roller 14 starts feeding the banknote bundle 18, banknotes in the banknote bundle 18 are largely skewed one by one and fed toward the feeding roller pair 15. The feeding roller pair 15 feeds the bill that is skewed greatly toward the discriminator 30 to the conveying path. The discriminator 30 discriminates that the banknote is an unacceptable banknote.

  FIG. 8 is a graph showing the relationship between the frequency at which the rear end of the banknote bundle becomes positions a, b, c, and d and the width of the upper space 11a. In the graph, the vertical axis represents the total number of bills inserted into the deposit / withdrawal port 24 as 100%, and the horizontal axis represents the case where the width of the upper space 11a is 3 mm, 5 mm, and 10 mm.

  In the case where the width of the upper space 11a is 3 mm and 5 mm, although there is a slight difference in frequency, both indicate that the bill bundle rear end may be at the positions c and d. This is considered to be because if the upper space 11a is narrow, friction between the banknote receiving space 11 and the deformed banknote becomes large, and the banknote bundle cannot be fully contained in the banknote receiving space 11. In this case, since the rear end portion of the banknote bundle is hit by the hook 8, skew appears as shown in FIG. 7 (d).

  And when the width of upper space 11a is 10 mm, it has shown that there is no case where a banknote bundle rear-end part becomes position c and d. In this case, since the rear end portion of the banknote bundle is not hit by the hook 8, there is a very low possibility that skew will appear as shown in FIG.

  5 and FIG. 8 collectively, the width of the upper space 11a is 3 mm or more and 10 mm or less, and a slight tolerance is observed in the vertical direction. It can be said that the frequency becomes extremely low.

  Furthermore, judging from FIG. 8, it is found that the area of the upper space 11a is preferably 10 mm, which is best. Thereby, even if it is a deformation | transformation banknote, when it is a normal ticket, the deposit banknote acceptance rate of the paper sheet handling apparatus 19 improves markedly.

  The present invention relates to a paper sheet handling apparatus that can accept a normal paper sheet without returning it to the insertion slot when it is a normal note even if the paper sheet inserted from the insertion slot is a deformed paper sheet. Can be used.
