Description

Paper discharge and accumulation device, and circulating paper processing device

The present invention relates to a paper discharge and accumulation device and a circulating paper processing device.

In the paper money handling devices such as automatic vending machines, game media lending machines in amusement parks, ticket machines, deposit and withdrawal devices, and money changers that have the function of providing various goods and services by receiving inserted paper money, a circulating type of paper money handling device that can receive, store, and withdraw paper money of multiple denominations is known. The circulating paper money handling device is equipped with a paper money storage unit, which is used to store paper money prepared in advance for withdrawal and paper money inserted during operation according to denomination or in a mixed denomination state. The banknote storage section includes: a circulating banknote storage section that stores banknotes and has the function of withdrawing banknotes to the outside for change, and a recycling banknote storage section (recycling warehouse) that recycles all banknotes in the banknote processing device at the end of business.

As a circulating banknote storage unit, a type of storing banknotes between tapes that are wound in a spiral shape (spiral shape) on the outer peripheral surface of a circulating drum is known, as in Patent Document 1 "Banknote Handling Device". The device described in the document is only equipped with a payment and receipt unit, and the payment and receipt banknotes (change banknotes) are received into the machine and paid out from the payment and receipt unit. When the banknotes that have been stacked and accumulated on the outer circumference of the circulating drum through the belt body are withdrawn as change, the circulating drum is rotated in the withdrawal direction and each belt body is sent out in the withdrawal direction, and the banknotes on the outer circumference of the circulating drum are sent out one by one, and are temporarily retained in a stacked state on the outer circumference of the banknote retaining drum and then withdrawn toward the payment department.

In the paper processing device described in Patent Document 2 (Japanese Patent Gazette No. 6450041), a payment port for withdrawing change is provided separately from the payment and receipt port for receiving or returning banknotes, and the payment port is configured to be withdrawn directly from the circulating banknote storage unit to the payment port. In this configuration, when withdrawing multiple banknotes as change, the banknotes are discharged one by one from the circulating banknote storage unit to the payment port, and after the user takes out the first banknote, the subsequent banknotes after the second are discharged in sequence. However, in such a type, the time required to pay all the banknotes becomes longer, and there are problems such as an increase in the burden on the user and a decrease in the machine operation rate. In contrast, there is another type in which the banknotes discharged one by one from the circulating banknote storage unit are accumulated in a continuous overlapping state on a payment tray provided at a payment port dedicated to payment, and after all the banknotes are discharged and accumulated, they are taken out in batches from the payment tray, thereby shortening the waiting time of the user. However, in the case of a circulating banknote storage unit equipped with a circulating roller, since the banknotes are wound and held on the outer peripheral surface of the circulating roller, a rolling mark is formed on each banknote along the long side direction, and the banknote to be paid will also be in a state where the rolling mark is left. In particular, if banknotes with upwardly curved long-side shapes (the long-side center protrudes upward and the two ends tilt downward) are discharged one by one onto the payment tray, even if the rear end of the first discharged banknote is held by floating pressure using the banknote pressing rod, the downwardly tilted front end of the subsequent banknote will still collide with the first accumulated banknote, causing poor accumulation such as pushing it off the payment tray and causing it to fall.

Furthermore, if even one of the banknotes discharged onto the payment tray has extremely low strength (rigidity), the position of the banknote on the payment tray will naturally cause the alignment of subsequent banknotes to deteriorate. That is, the banknote discharged onto the payment tray with sufficient strength pushes the banknote pressing rod upward while falling onto the payment tray, and is pressed by the banknote pressing rod after falling. However, the wrinkled banknotes with significantly reduced strength cannot fully push up the banknote pressing rod during the discharge process, and will be discharged onto the payment tray while being bent, and finally stop in the space between the banknote pressing rod and the upper surface of the payment tray in a bent state, which is an abnormal discharge state. If the subsequent banknotes are discharged in this state, the wrinkled banknotes discharged previously will become an obstacle and cannot stop at the normal accumulation position. Therefore, when the banknotes for change are discharged and accumulated one by one onto the payment tray, it is difficult to accumulate them in an aligned state on the payment tray.

[Effect of the invention]

According to the present invention, in a circulating paper processing device, it is possible to prevent the paper exiting from the circulation unit from causing poor accumulation on the payment tray.

The present invention is described in detail below by using the embodiments shown in the drawings. [Banknote processing device] 《Overall structure》 Figure 1 is a longitudinal sectional view of a banknote (paper) processing device having a banknote (paper) discharge accumulation device of an embodiment of the present invention. In this embodiment, although the device for processing banknotes as an example of paper is described, the paper discharge accumulation device and paper processing device of the present invention are also applicable to general processing devices for paper such as cash, tickets, and securities in addition to banknotes. In addition, the shape of the paper in this embodiment is mainly a quadrilateral such as a rectangle or a square, that is, a rectangle, but it is not limited to a rectangular sheet.

The circulating banknote processing device (hereinafter referred to as "banknote processing device") 1 shown in FIG1 is equipped or attached to a banknote operation device such as an automatic vending machine, a ticket machine, a game medium lending machine in a game center, a deposit and withdrawal device, and a money exchange machine, and performs a means of receiving and processing banknotes and withdrawing banknotes as change, etc. The banknote processing device 1 is described in detail below. The banknote processing device 1 generally includes: an outer casing 3 constituting an outer casing, a payment processing unit M for conveying banknotes received into the outer casing along the long side direction through the required route into the machine and discharging them out of the machine, a banknote storage unit N for storing banknotes conveyed from the payment processing unit M and discharging the stored banknotes to the payment processing unit M, a conveying mechanism for conveying banknotes through various routes, and a control means (CPU, MPU, ROM, RAM, etc.) 1000 for controlling various control objects.

The payment processing unit M includes a payment port (input port) 5, a withdrawal port (discharge port) 7, a batch payment receiving section (introduction section) 11, and an identification section 15. The payment and receipt port 5 receives a single banknote or a batch of banknotes containing banknotes of different denominations, and serves as a return port when the rejected payment banknotes are returned; the withdrawal port 7 withdraws the banknotes for change from the banknote storage unit N; the batch payment receiving unit 11 separates the banknotes (bundles) received and placed in the payment and receipt port 5 one by one and introduces them into the device body through the payment banknote conveying path (introduction unit) 9a; the identification unit 15 is arranged along the conveying path of the payment banknote conveying path 9a and uses an optical sensor and a magnetic sensor to determine the denomination, authenticity, etc. of the payment banknotes. The payment processing unit M is composed of the first unit M1 and the second unit (banknote discharge and accumulation device, batch withdrawal unit) M2. The first unit M1 is equipped with: an unillustrated custody unit (temporary storage unit), an unillustrated withdrawal and accumulation unit (banknote return accumulation device), etc. The custody department temporarily retains the receipt banknotes that have passed through the payment and collection port (inlet) 5, the receipt banknote conveying path 9a, the batch payment department 11, and the identification department 15 until the predetermined number of banknotes are reached. When the receipt is confirmed, the banknotes are successively sent to the storage departments 30, 40, and the recycling warehouse 50 described later. When the banknotes are returned due to cancellation of a refund request, the banknotes are successively sent to the withdrawal accumulation department not shown in the figure. The withdrawal accumulation department accumulates the banknotes for return and the rejected banknotes (hereinafter referred to as "returned banknotes") conveyed from the custody department and withdraws them to the payment and collection port 5. The further detailed description of the first unit M1 is omitted because it is not relevant to the present invention. The second unit M2 constitutes the banknote discharging and accumulating device of the present invention, and includes: a payment tray (discharging tray) 700 provided at the discharging port (discharging port) 7, a discharging conveying and accumulating unit 500 for conveying, discharging and accumulating the discharging banknotes (discharging sheets) discharged one by one from each storage unit 30, 40 to the payment tray 700, etc. A unit installation space E is provided between the first unit M1 and the banknote storage unit N, and in the space E, a banknote discharging device without a batch discharging function for making a change and a second unit M2 with a batch discharging function can be replaced and loaded and unloaded. That is, in the installation space E, a conventional banknote discharging device having a structure different from that of the second unit M2 can be installed. The conventional banknote dispensing device is configured such that subsequent banknotes after the second banknote are not dispensed until the user takes out the banknotes discharged one by one from the banknote storage unit N and discharged onto the payment tray. In contrast, the second unit M2 of the present invention, i.e., the banknote dispensing and accumulating device, continuously discharges banknotes one by one from the banknote storage unit N onto the payment tray, and after the required number of banknotes are accumulated, the user can take them out in batches.

The banknote storage unit N includes: the first and second circulating banknote storage sections (circulating banknote storage device, circulating unit) 30, 40, and a recycling bin (recycling banknote storage section) 50. The first and second circulating banknote storage units 30, 40, when the receipt of the payment banknotes is confirmed, store the banknotes that are sent out one by one from the custody unit and transported on the storage banknote transport path 9b according to the denominations so that they can be freely accessed; the recovery warehouse (recovery banknote storage unit) 50 is installed in the storage space below the second circulating banknote storage unit 40 in a manner that can be loaded and unloaded from the front and side. At the end of business, all denominations are recovered from each circulating banknote storage unit, and high-value banknotes that will not be used as change and surplus banknotes that cannot be accommodated in each circulating banknote storage unit are recovered. The conveying mechanism is equipped with: a motor, a solenoid, a pulley, a belt, a gate, etc. for generating and transmitting a driving force for conveying banknotes along each conveying path 9a, 9b and other conveying paths. The control means 1000 controls the payment processing unit M, the banknote storage unit N, and the conveying mechanism and other control objects.

The first and second circulating banknote storage sections 30 and 40 of this example are respectively provided with two circulating rollers (31, 35, 41, 45) with a maximum storage capacity of 30 sheets. Each circulating roller 31, 35, 41, 45 is suitable for storing and circulating banknotes between two long strips (long films) that are overlapped and wound on the outer circumference in a vortex shape (spiral shape).

<Various actions of the banknote processing device> Next, the outline of the collection action, confirmation action, payment action, and collection action in the banknote processing device 1 shown in FIG. 1 is described.

First, during the payment operation, if one or more banknotes are inserted from the payment port 5, the sensor will detect the banknotes, and the control means 1000 that receives the signal from the sensor will activate the conveying mechanism and use the batch payment unit 11 and the payment banknote conveying path 9a to receive the banknotes. The batch payment unit 11 takes out the top banknotes from the banknote bundle inserted into the payment port 5 one by one and conveys them to the identification unit 15. The banknotes determined as acceptable by the identification unit 15 are conveyed to the custody unit (not shown), and are temporarily retained by being wound around the outer periphery of the custody roller one by one, waiting for the confirmation of the payment. As for the return processing of the banknotes temporarily retained in the custody unit, since it has no direct relationship with the present invention, its description is omitted.

The receipt banknotes temporarily retained in the escrow department are sent out one by one from the escrow department at the stage of receipt confirmation. The banknotes used as change are stored in the circulating banknote storage units 30 and 40 according to the denomination through the storage banknote transport path 9b, and the banknotes not used as change are stored in the collection warehouse 50. When withdrawing banknotes as change, the banknotes stored in the flow banknote storage units 30 and 40 that store banknotes according to denominations are taken out, and the denominations, authenticity, etc. are identified by the identification unit 70 provided on the storage banknote conveying path 9b. As long as the banknotes are returnable, they are withdrawn to the withdrawal port 7 as change. On the other hand, when the banknotes are determined to be non-returnable by the identification unit 15, they are temporarily stored in the custody department and then transferred to the collection warehouse 50 for storage. During recycling, at the end of business, etc., the banknotes stored in the recycling banknote storage units 30 and 40 are once accumulated in the custody unit and then stored in the recycling warehouse 50.

<Circulating banknote (paper) storage section> The circulating banknote storage section (circulating banknote storage device = banknote storage section) 30, 40 is roughly equipped with: two circulating units (circulating roller units) 100, 200 in the housing 60, and a distribution section (falpper) 310 on the circulating unit side that switches the conveying path (introduction path, exit path) of banknotes to either side. The circulating units 100, 200 are means for receiving banknotes conveyed into the housing 60 by the driving force from the motor (not shown) and sending the stored banknotes out of the housing.

The circulating banknote storage section 30, 40 comprises: a motor not shown in the figure, a first circulation unit (first circulation drum unit) 100 and a second circulation unit (second circulation drum unit) 200 which respectively receive and store the banknotes transported by the driving force from the motor and send out the stored banknotes, a distribution means (tongue valve) 310 which distributes the transported banknotes to any one of the circulation units by changing its posture (position), and a distribution means driving mechanism (tongue valve driving mechanism) which drives the distribution section (tongue valve) 310.

The following describes the structure of the circulating banknote storage section (circulating banknote storage device) 30, 40. The circulating units 30 and 40 have circulating rollers 31, 35 and circulating rollers 41, 45, respectively. The circulating rollers 31, 35 and circulating rollers 41, 45 store banknotes one by one by stacking them on the outer peripheral surface by forward rotation, and discharge the banknotes on the outer peripheral surface one by one by reverse rotation. For example, 1000 yen banknotes are stored in the circulating unit 30, and 5000 yen banknotes are stored in the circulating unit 40. On the storage banknote conveying path 9b, a first distribution section 61 is arranged to distribute the receipt banknotes conveyed to the banknote storage unit N to the circulating banknote storage section 30 or 40 (recycling bin 50). On the first distribution section 61, a distribution piece 61a is arranged to distribute the receipt banknotes conveyed from the receipt banknote conveying path 9a to the circulating banknote storage section 30 (in-housing conveying path 9c) or the circulating banknote storage section 40 (recycling bin 50). On the downstream side of the first distribution section 61, a second distribution section 65 and a distribution piece 65a are arranged to distribute the receipt banknotes to the circulating banknote storage section 40 or the recycling bin 50. Since the circulating banknote storage sections 30 and 40 have roughly the same structure, the following description will focus on the circulating banknote storage section 30.

The circulation unit 100 on the front side is equipped with: a tongue valve 310 for distributing the banknotes transported sequentially through the distribution plate 61a and the conveying path 9c in the housing to either of the circulation rollers 31 or 35; a circulation roller (first circulation roller) 31 on the front side for fixing one end of each belt body (film) T1, T2 on the front side and winding the two belt bodies T1, T2 in an overlapping state on the circumference when rotating in the clockwise direction; and a first circulation roller 31 for supplying the outer circumference of the first circulation roller 31 with banknotes. A first bobbin 105 is provided on which the first belt body T1 is spirally wound (multi-layered) and held so as to be rotatable forward and reverse, a plurality of guide rollers 106a are provided to guide the first belt body T1 drawn out from the first bobbin to the outer peripheral surface of the first circulating drum, a second bobbin 110 is provided on which the second belt body T2 supplied to the outer peripheral surface of the first circulating drum 31 is spirally wound and held so as to be rotatable forward and reverse, and a guide roller 111a is provided to guide the second belt body T2 drawn out from the second bobbin to the outer peripheral surface of the first circulating drum. Each belt body T1, T2 is respectively wound around the outer peripheral surface of the first circulating drum along the route of each guide roller 106a, each guide roller 111a, or sent from the first circulating drum to each bobbin 105, 110. The forward and reverse rotation of each bobbin 105, 110 is performed by a motor (not shown).

The banknotes conveyed from the first distribution section 61 toward the first circulation drum 31 are guided into the contact running area TA where the two belt bodies T1 and T2 run overlapping at the nip portion n of the guide roller 106a and the guide roller 111a at the final position, and are sandwiched between the two belt bodies while being accumulated on the outer peripheral surface of the first circulation drum rotating in the winding direction (counterclockwise). When the banknotes accumulated between the belt bodies on the outer periphery of the first circulation drum 31 are discharged one by one to the outside of the circulation unit 100, the first circulation drum 31 is rotated in the delivery direction (counterclockwise) while the tubes 105 and 110 are rotated in the winding direction, and the belt bodies T1 and T2 are sent back along the same route as when they were sent out from the tubes 105 and 110 and wound around the tubes. The banknotes clamped between the belt bodies are discharged from the clamping part n to the first distribution part 61, the housing conveying path 9c, and the storage banknote conveying path 9b in sequence.

The final guide roller 106a for the first belt body T1 and the final guide roller 111a for the second belt body T2 form a clamping portion n, and after the clamping portion, the two belt bodies T1 and T2 are wound around the outer peripheral surface of the first circulating drum 31 in an overlapping state.

The circulation unit 200 on the back side has the same structure as the circulation unit 100 on the front side, and the same symbols are given to the same parts and detailed descriptions are omitted. In addition, the directions of the rolling marks formed by the banknotes accumulated on the outer peripheral surfaces of the circulation rollers 31, 35 constituting the circulation unit 100 and the circulation rollers 41, 45 constituting the circulation unit 200 are opposite. That is, the circulation rollers 31, 35 roll up the banknotes when rotating clockwise, and rotate counterclockwise when withdrawing. Therefore, the banknotes discharged to the payment tray 700 through the storage banknote conveying path 9b have rolling marks with the center of the long side bulging upward (the two ends of the long side tilting downward), that is, they are upward rolling marks. On the other hand, the rolling marks of the banknotes accumulated on the outer periphery of the circulating rollers 41, 45 are downward rolling marks with the center of the long side bulging downward.

[Banknote discharge and accumulation device: first embodiment] 《Basic structure》 Figure 2 is a three-dimensional diagram showing the structure of the main part of the second unit M2 of the first embodiment, Figure 3 is a front view of the forming mechanism when viewed from the discharge side, Figure 4 is a three-dimensional diagram of the forming mechanism when viewed from the discharge side, Figures 5(a) and (b) are front views showing the state in which the banknote is formed into a shape with a predetermined strength by the forming mechanism, and explanatory diagrams showing the shape of the short side of the ejected banknote after forming, and Figure 5(c) is an explanatory diagram of the case in which the short side of the banknote is formed into an M shape. FIG6(a) shows the positional relationship between the banknotes just discharged from the forming mechanism and the accumulated banknotes, and a front-side perspective view of the guide member, and FIG6(b) is a perspective view showing the shape of the banknotes after forming. FIG7 is a perspective view showing the structure of the guide member, and FIG8 is a longitudinal section view showing the structure of the payment tray.

The second unit (banknote discharge accumulation device, batch discharge unit) M2 includes: a discharge port 7, a discharge conveying accumulation unit 500 that conveys the discharged banknotes (discharged paper) B paid from each storage unit 30, 40 to the discharge port 7, and a payment tray (discharge tray) 700 that is set at the discharge port 7 and accumulates (layers) the banknotes discharged from the discharge conveying accumulation unit. The second unit M2 is a means for discharging and accumulating the banknotes discharged one by one from the circulation unit 30, 40 onto the payment tray 700. The circulation unit 30, 40 receives and stores the banknotes that are transported in, and discharges the stored banknotes to the outside. The second unit M2 can continuously discharge and accumulate the multiple withdrawn change bills one by one with the short side in front onto the payment tray 700. When the accumulation is completed, the user can take out the accumulated bill bundles in batches. The bills on the payment tray can be taken out after all the bills are discharged.

As shown in FIG. 1 and FIG. 11, the discharge conveying and accumulating section 500 constituting the second unit M2 is provided with: a discharge conveying path 510 for discharging and conveying banknotes toward the payment tray, a discharge conveying mechanism 520 for imparting a conveying force to the banknotes on the discharge conveying path 510, a short-circuit for discharging the withdrawn banknotes B (hereinafter referred to as "banknotes B") discharged onto the payment tray 700, and a short-circuit for discharging the withdrawn banknotes B. The forming mechanism (rigidity imparting means) 550 is used to give stiffness (rigidity and shape retention, stiffness) to the entire length of the banknote B by forming the banknote B in a predetermined shape (shape in the short side direction) over the entire length in the long side direction, and the paper passing sensor 580 is used to detect the entry of the front end of the banknote B relative to the forming mechanism and the discharge of the rear end. The banknote B that has entered the discharge conveying path 510 is conveyed to the forming mechanism 550 by conveying components such as the conveying roller 517 constituting the discharge conveying mechanism 520. The discharge conveying path 510 is equipped with a conveying guide 510a that clamps the banknote B from the top and bottom, and a conveying roller pair 517 that clamps the banknote B while conveying it. Even if it is a banknote with a rolling mark or a banknote with reduced strength, it can still be conveyed while being corrected (deformed by pressure) to a straight and flat posture. Therefore, the banknotes conveyed in the discharge conveying path become a state with a certain strength or more. However, the posture correction in the discharge conveying path is temporary, and the rolling mark is not completely corrected. That is, when the banknote with a rolling mark is discharged to the payment tray without passing through the forming mechanism, the rolling mark will be revived on the payment tray. The discharge conveying mechanism 520 is provided with rollers 512a, 512b, 512c for conveying the bills (discharged bills) B which are paid from the storage sections 30, 40 and rise along the storage bill conveying path 9b to the forming mechanism 550, and rollers 512a, 512b, 512c for guiding the bills (received bills) conveyed from the first unit M1 to the side of the bill storage unit N. The tongue valve 514 switches between the posture of guiding the conveying direction of the banknotes toward the second unit M2 (forming mechanism 550), the tongue valve driving means (solenoid, etc.) not shown, the discharge conveying path 510 to the forming mechanism, the conveying roller pair 517 provided in the discharge conveying path, the motor and solenoid as the driving source of each driving object, etc. The rollers 512a, 512b rotate forward when conveying the receipt banknotes introduced from the first unit M1 toward each storage unit 30, 40, and rotate reversely when feeding the banknotes B into the forming mechanism 550. In the state shown in the figure, the tongue valve 514 is in a posture to transport the banknote B that has risen along the storage banknote conveying path 9b to the forming mechanism 550. By rotating the tongue valve 514 clockwise at a desired angle, it is transferred to a posture that connects the storage banknote conveying paths 9b and 9a.

<Forming mechanism> The forming mechanism 550 is a means for forming the short side shape of banknotes with various curling marks, folds, wrinkles, etc., or banknotes with partially or completely reduced strength (defective banknotes) in a predetermined manner along the entire length of the long side direction, thereby strengthening the strength in the long side direction and correcting it into a shape suitable for accumulation. The correction effect (forming effect, shape-keeping effect after forming) of the forming mechanism is not temporary, and the corrected shape can be maintained even after being discharged onto the payment tray. In the example described in the following embodiment, a banknote with a rolling mark with the long side facing upward formed by a circulating roller is formed by a forming mechanism to give strength (correct the rolling mark), but the forming mechanism can be applied to banknotes with various characteristics other than rolling marks, deformed banknotes, banknotes with reduced strength, etc., and banknotes with defective properties that may cause poor landing and poor accumulation when discharged onto the payment tray without going through the forming process.

The specific configuration example of the forming mechanism 550 is explained with reference to FIGS. 2 to 5 . The short side shape of the banknote, as shown in FIGS. 5(a) and (b), refers to the shape of the edge when the short side of the banknote is viewed from the front (front shape). The forming mechanism 550 generally includes: a rotating shaft 552, a disc-shaped (roller-shaped) central flange 605, two drive rollers 555, 600, and disc-shaped outer flanges 607, 609. The rotating shaft 552 is supported by the bearing part 553 so that both ends can rotate freely in a horizontal position; the central flange 605 is used to fix the shaft core to the appropriate position of the rotating shaft, which is the position of the rotating shaft corresponding to the central part of the width direction of the discharge conveying path 510 in this example; the two driving rollers 555, 600 are used to fix the shaft core to the rotating shaft at positions separated by a predetermined interval L1 on both sides of the central flange 605 in the axial direction; the outer flanges 607, 609 are used to fix the shaft core to the rotating shaft at positions separated by a predetermined interval L2 on the outer sides of the driving rollers 555, 600 in the axial direction. In other words, a central flange 605 with a large width is arranged in the same axial core shape at the middle position of the drive rollers 555, 600, and outer flanges 607, 609 with a small width are arranged at a predetermined distance L2 on the outer side of the axial direction of each drive roller. The width W1 (6 mm) of the contact surface (peripheral surface) between the central flange 605 and the banknote is set to be wider than the width W2 (2 mm) of the contact surface between each outer flange 607, 609 and the banknote. The reason why the width W1 of the central ridge is set wider is that, as described later, when the width of the central ridge is too small, the gap G2 between the central ridge and the open portion 673 of the pressing rod 670 becomes too large, and part of the banknotes will fall into the gap, and the discharged banknotes will be downward, reducing the force of the pressing rod to push upward. The ratio of the width W1 of the central ridge to the width W2 of the outer ridge is, for example, about 4:1.

The outer diameter of the central flange 605 and the outer flanges 607, 609 is larger than the outer diameter of each driving roller 555, 600. In order to avoid deformation when contacting with banknotes, each flange is a disc component made of resin, metal material, etc. with sufficient hardness. Directly above each driving roller 555, 600, a tension roller 556, 601 as a driven roller is arranged in a one-to-one correspondence with each driving roller, and a clamping portion n1 is formed between the tension roller and the outer peripheral surface of each driving roller. The outer circumference of each drive roller 555, 600 and tension roller 556, 601 is made of a material with sufficient friction resistance to avoid slipping between it and the banknote. The height position T1, T2 of the uppermost part of the outer circumference of each flange 605, 607, 609 is higher than each clamping part n1 of each drive roller and each tension roller. Therefore, when the banknote B passes through the rotating shaft 552, it is deformed by applying pressure and pushing to each clamping part n1 and flange, so that each protrusion P1, P2, the upward bevel S2, and the protrusion P3 can be formed (refer to Figure 5 (a) (b)).

Alternatively, a limiting member 611 may be arranged with a gap G1 between the uppermost portion T2 of each outer flange 607, 609 to limit the extension direction of the two ends of the short side of the banknote. As the limiting member 611, a fixed member or roller with low friction resistance to the banknote may be used. When a banknote with a small width is discharged from the forming mechanism, the two ends of the short side of the banknote may not sag but stand up excessively. In this state, the two raised ends of the banknotes accumulated on the discharge tray become the cause of collision when the next banknote is discharged, and become the cause of the preceding banknote falling from the discharge tray. To solve such a problem, it is effective to limit the extension direction of the two ends of the short side by using the limiting member 611. When a wide banknote is discharged from the forming mechanism, if the short side ends of the banknote are excessively raised due to the W-shaped formation, they may become higher than the height of the space on the payment tray and interfere with the ceiling of the space (frame 660). At this time, there is a risk of the banknote getting stuck (jam). By using the limiting member 611 to limit excessive vertical rise in advance during the forming process, the risk of jamming can be reduced. Especially for banknotes with strong strength, the short side ends of the banknote may not sag but remain in an upright state. After the raised ends accumulate on the payment tray, they may block the discharge path. It is effective to use the limiting member to limit the extension direction of the short side ends in advance.

In the example shown in FIG. 5(a)(b), the forming mechanism 550 forms an upward protrusion (bent portion protruding upward) P1, a downward protrusion (bent portion protruding downward) P2, and an upward protrusion P3 alternately along the short side of the banknote so that the short side of the banknote B becomes roughly symmetrical, and the two end sides S2, S2 of the short side of the banknote are inclined upward (protruding obliquely upward). The upward protrusion P1 has: a top P1', and oblique sides S1, S1 extending obliquely downward to the left and right (outward) from the top P1'. The downward protrusion P2 has: a top (bottom) P2', and oblique sides (end sides) S2, S2 extending obliquely upward to the left and right from the top P2'. An upward protrusion P3, P3 is formed at the terminal end of each oblique side S2, S2. The top P1' of the central protrusion P1 is formed at a position corresponding to the outer peripheral surface of the central flange 605, the top P2' of the left and right protrusions P2 is formed at a position corresponding to the clamping portion n1 of the drive roller 555, 600 and the tension roller 556, 601 (the final roller pair), and the top P3' of the outer protrusion P3 is formed at a position corresponding to the outer peripheral surface of the outer flange 607, 609.

That is, the central protrusion P1 is formed by the central ridge 605 pushing the central part of the banknote upward while the left and right clamping parts n1 are pressed to the left and right positions. The downward protrusion P2 is formed by the clamping parts n1 of the drive roller 555 and the tension roller 556, and the clamping parts n1 of the drive roller 600 and the tension roller 601 pushing downward. The outer oblique side S2 and the protrusion P3 are formed by the outer ridges 607, 609 and the limiting member 611 while the clamping parts n1 are pressed. That is, when the banknote B passes through, an upward protrusion P1 is formed in the center of the short side of the banknote B (the center in the width direction), a downward protrusion P2 is formed on the left and right sides of the protrusion P1, and upward protrusions P3, P3 are formed on the left and right sides of each downward protrusion P2, P2. In this way, the two end edges of the banknote can be corrected (modified) to be raised (tilted upward) to form oblique sides S2, S2. The short side shape of the formed banknote becomes roughly symmetrical. The protrusions (P1, P2, P3) and oblique sides S1, S2 as the forming parts are formed continuously over the entire length of the long side direction of the banknote. Therefore, the curling marks (curved shape) formed along the long side direction of the banknote discharged onto the payment tray are corrected, so that the shape of the long side direction of the banknote becomes approximately flat or approximately close to straight, and the shape is maintained (shape-keeping). That is, the short side of the banknote B is bent (curved) at multiple locations to alternately form the upward protrusion P1, the downward protrusion P2, and the upward protrusion P3, thereby eliminating the curling marks of the banknote whose shape is curved when viewed from the long side direction, and making the shape viewed from the long side direction approximately straight (non-curled shape). In other words, by alternately providing vertical protrusions along the short sides, the strength (rigidity) of the banknote is increased along the entire length of the long side, and the force (shape-retaining force) to maintain a roughly flat or roughly straight shape can be given.

Therefore, the long side direction of the banknotes released from the forming mechanism 550 can be oriented upward, and the upward amount corresponding to the upward orientation can prevent collision with the rear of the accumulated banknotes. In particular, when the rear end of the accumulated banknotes is inclined upward due to its habit, it is easy to collide with the front end of the subsequent banknotes, but the subsequent banknotes that are flat and oriented upward due to the strength enhancement have a better collision prevention effect on the accumulated banknotes. The banknote portion corresponding to the downward protrusion P2 is discharged from the forming mechanism in a state where it is clamped by the clamping portion n1 of each final roller pair, so it does not sag during discharge. After discharge, each protrusion P1, P2 is in a state of being shaped like a mountain (valley) and maintaining its shape, and a strong tension is applied to each oblique side S1 connecting the protrusions, so each protrusion will not sag.

Each oblique edge S1 is formed by being stretched between the outer peripheral surface of the central flange 605 and the clamping portion n1 of each final roller pair under a state of applying sufficient tension. Each oblique edge S2 is formed by being stretched between each clamping portion n1 and the outer peripheral surface of the outer flanges 607, 609 under a state of applying sufficient tension. Therefore, each oblique edge S1, S2 will not be loose or droop during and after being discharged from the forming mechanism. Even in the case of a banknote with a longer short side, the protrusion P2 is in a clamped state during discharge and is originally inclined upward, so each oblique edge S2 will not droop to the extent of interfering with the accumulated banknotes. That is, even after being ejected from the forming mechanism, each protrusion P1, P2 is in a mountain (valley) shape, and strong tension is applied to each oblique side S1 connecting the protrusions and each oblique side S2 on the outside, so each oblique side S2 does not sag significantly. Even if each oblique side sags after being ejected, the amount of sag is not large. Therefore, the total height h1 after forming can be suppressed to be smaller, and the vertical dimensions of each part constituting the forming mechanism can be miniaturized.

The tops P1', P2', P3' of each protrusion P1, P2, P3 are not formed into sharp or blunt protrusions, but are formed into shapes after the shapes of the outer peripheral surfaces of the central flange 605, the drive rollers 555, 600, and the outer flanges 607, 609 are transferred, that is, they are roughly flat. In short, regardless of the shape of the tops of each protrusion P1, P2, P3, as long as the protrusions are continuously formed over the entire length of the long side of the banknote, the bending shape of the banknote in the long side direction can be corrected into a flat or nearly straight shape, and the purpose of strengthening strength (ensuring shape retention) caused by forming can be achieved. As long as the outermost end sides S2 are configured to be inclined upward, the number of protrusions P1, P2, and P3 can be any number. In other words, it does not have to be a W shape.

In the present embodiment, the height position of the protrusion P1 in the center of the formed banknote B and the height position of the protrusions P3, P3 on the outside are set to be the same, but the height position of the protrusions P3, P3 can also be set to be higher or lower than the protrusion P1. When the height position of each top P3' of each protrusion P3 is set to be higher than the height position of the top P1' of the protrusion P1, the outer diameter of the outer flange 607, 609 becomes larger than the outer diameter of the central flange 605. In this case, the uppermost portion T2 of the outer peripheral surface of the outer flange is located at a higher position than the uppermost portion T1 of the central flange. Therefore, the possibility of each oblique side S2 and each top P3' of the discharged banknote being hooked to the rear of the accumulated banknotes is further reduced. Although the height positions of the downward protrusions P2 and P2 are the same, they can also be different. In the embodiment shown in the figure, the short side shape after forming is a left-right symmetrical shape, which is just an example. As long as it can give sufficient strength, it does not have to be left-right symmetrical. In addition, the bevels S1 and S2 between the protrusions of the bill after forming can be stretched in a substantially straight line with sufficient tension as shown in Figure 5 (b) as long as the strength of the bill (especially the strength in the short side direction) is of a normal level. Another advantage of forming the bill into a W shape, that is, making the bevels S1 and S2 at both ends tilt upward, is that the total height h1 after forming can be made the minimum required and sufficient strength can be ensured. According to experiments, the total height h1 can be suppressed to about 2.5mm, the diameters of the rollers and flanges that constitute the forming mechanism can be compacted, and the volume of the formed banknote will not become very large.

However, as described later, when the strength of the banknote is significantly reduced, the tension of the oblique sides S1 and S2 between the protruding parts is reduced and the banknote is easily loosened, thereby reducing the shape retention during and after discharge from the forming mechanism. The countermeasures to this problem are described in the third embodiment. As shown in Figure 5(c), if the short side of the banknote B is formed into an M shape, the two end sides S3 of the short side will tilt downward, making it easy to sag. Therefore, when the banknote is discharged onto the payment tray, the two end sides S3 will hook onto the banknotes accumulated on the payment tray in advance (especially the banknotes with the tendency of the rear end to protrude upward), causing them to fall. If formed into an M shape, the outer end S3 becomes easy to exceed the height position of the downward protrusion P4 and droop downward greatly, which becomes the cause of the increase in the hook between the accumulated banknotes. In particular, in the case of banknotes with longer short sides, the outer end S3 becomes longer than the one shown in the figure, so the drooping state is more serious. Therefore, it is not possible to adopt a forming shape in which the two ends of the short side are tilted or drooped downward.

In addition, the banknotes issued by countries around the world are roughly divided into: narrow banknotes with the maximum size of the short side (maximum width) less than 72mm, such as the United States, Canada, Australia, etc., and wide banknotes with the maximum width of 72mm or more and less than 86mm, such as Japan, the Euro, and Macau. On the other hand, when manufacturers of banknote processing devices need to manufacture banknote processing devices suitable for countries where narrow banknotes are circulated and for other countries where wide banknotes are circulated, it is disadvantageous to manufacture devices of different specifications according to countries. That is, preparing two models of banknote processing devices that have no structural difference except for the width of the conveying path, and manufacturing and shipping them according to orders is obviously disadvantageous from the perspective of manufacturing cost, inventory management fee, etc. In order to deal with such disadvantages, the following countermeasures are adopted, that is, only one model with a wide conveying path that can convey wide banknotes is prepared, and it can also be shared for narrow banknotes. In particular, when the second unit M2 is incorporated into the banknote processing device 1, the forming mechanism 550 is required to be a structure that can be shared regardless of the size of the short side of the banknote and formed into a shape that can give sufficient strength.

However, in the circulation unit equipped with a circulation drum, the banknotes are stored in a state of being wound around the outer peripheral surface of the circulation drum, so the banknotes have a tendency to bend along the long side direction (curling marks). In particular, when the banknotes discharged from the circulation unit and discharged onto the payment tray 700 have upward curling marks with the center of the long side bulging upward, the following problem occurs: the front end (tilted downward) of the newly discharged banknotes will hit the rear end of the accumulated banknotes, pushing the accumulated banknotes from the payment tray and causing them to fall. Even if there are no accumulated banknotes, a newly discharged banknote with an upward curling mark may slide on the payment tray, pass over the front edge of the payment tray and fall, or bend between the banknote pressing rod and the upper surface of the payment tray because its front end is bent downward.

In the present invention, the forming mechanism 550 is used to form the shape of the short side direction of the banknote in a predetermined shape (a shape with strength) over the entire length to solve the problem in the past. In the forming mechanism 550 of this embodiment, in order to correspond to narrow banknotes with a maximum width of less than 72 mm, the interval L1 between the central flange 605 and each driving roller 555, 600, and the interval L2 between each driving roller 555, 600 and each flange 607, 609 are set to L1 = 8mm~9mm, L2 = 10mm~11mm. That is, when the short side is formed into a W shape as in the present embodiment, the positional relationship between each driving roller and each flange is set in such a way that the two end sides S2 of the short side direction of the narrow banknote are inclined upward.

On the other hand, if the positional relationship of each driving roller 555, 600 with the central convex edge 605 as the center and the positional relationship of each convex edge 607, 609 with the central convex edge as the center are set in this way in accordance with the narrow-width banknote, the wide-width banknote with a maximum width of 72 mm or more and less than 86 mm can also be given the same short-side characteristics as the narrow-width banknote. The short-side position of each protrusion P1, P2, and P3 is constant regardless of the short-side size of the banknote, but the length l1 of the top P3' of the outermost protrusion P3 varies according to the short-side size of the banknote B.

However, by determining at least the axial positions of the flanges 607, 609 on both sides, i.e., the interval between the flanges 607, 609, in a manner corresponding to the minimum banknote width, i.e., less than 72 mm, the layout of each drive roller and each flange can be constant and the wide banknote can be appropriately formed. That is, in the discharge conveying path 510, both the narrow banknote and the wide banknote are conveyed in a manner such that the center of their short sides is roughly consistent with the center of the width direction of the central flange 605, so that the positions (distances from the center of the short sides) of the upward protrusions P1, P3 and the downward protrusion P2 are the same, and only the length l1 of the portion extending outward from each protrusion P3 is different. If the length of the short side is less than 72mm, the length l1 of the top P3' of the outermost protrusion P3 becomes shorter, and if the length of the short side exceeds 85mm, the length l1 of the top P3' becomes longer. However, during discharge from the forming mechanism, each top P3' is clamped by the outer flanges 607, 609, so it can be prevented from sagging significantly. After discharge, as long as it is a banknote with normal strength, it can also be prevented from sagging.

On the other hand, because all the drive rollers and ridges are arranged so that they are located inside the short side dimension of narrow bills, which is 72 mm, if the short side of wide bills is deformed into an M shape, the two ends will protrude greatly downward. Therefore, the accumulated bills on the payment tray and the front ends of the newly discharged subsequent bills are likely to collide. As a result, the accumulated bills may be pushed out and fall from the payment tray, or the subsequent bills may be squeezed and deformed, resulting in poor accumulation.

<Impeller> Furthermore, the discharge conveying and accumulating section 500 is provided with an impeller 650. That is, the shaft core of the impeller 650 is fixed to the rotating shaft 552 at the outer side of the axial direction of each driving roller 555, 600 and the inner side position of each flange 607, 609. The impeller 650 is configured such that blades 654 of the same length are fixed at predetermined intervals in the circumferential direction on the outer periphery of the small-diameter base section 652 and the blades are protruded radially. In this example, three blades 654 are arranged at intervals of 120 degrees. The blades 654 are in the shape of narrow bands, and are made of a material that is easily elastically deformed, such as a rubber plate, and have a shape that is bent toward the direction of rotation at least as a whole. Alternatively, the impeller may be configured to bend due to centrifugal force when the impeller rotates.

The impeller 650 and the drive rollers 555, 600 are arranged in the same axis shape. According to the circumferential interval of each blade 654 and the setting of the rotation speed of the impeller, the blade may interfere with the banknotes discharged from the clamping part of the drive roller and the tension roller (the final roller pair), and there is a concern that the discharge is hindered. In order to eliminate such doubts, the banknote discharge speed and the rotation speed of the blade are set so that each banknote is discharged one by one and the discharge is completed in the circumferential interval of 120 degrees between one blade and the next blade. While the banknote passes through the final roller pair, no blade interferes with the banknote. After the rear end of the banknote separates from the final roller pair as described below, the blade rotating from above the banknote interferes with and contacts the banknote, and sweeps downward and backward.

The blade 654 of the impeller of this embodiment is a flat thin strip made of elastic material such as rubber, and a high friction area 656 is provided on its front end surface (the contact surface with the banknote), and small convex parts 656a and concave parts 656b are alternately provided in the high friction area 656. The convex part 656a constituting the high friction area 656 is made of a material having a higher friction coefficient than the material of the main body of the blade. If the surface in contact with the banknote is flat, the friction resistance will be reduced due to the adhesion of paper powder or dust, but by providing the high friction area 656 composed of concave and convex parts, it is possible to prevent the slip between the banknote and the high friction area 656. In particular, by allowing paper dust to enter the concave portion, the friction resistance caused by the paper dust can be prevented from being reduced, and by contacting the guide member, the high friction area itself is elastically deformed and stretches, so that the paper dust in the concave portion can be easily discharged, and the automatic cleaning function can be exerted. In addition, by setting up the high friction area 656, the durability of the front end portion of the blade that is easily worn due to sliding friction with the banknote can be improved. In the high friction area 656 of this embodiment, the convex portion 656a is a long and narrow rectangular parallelepiped extending in the width direction of the blade, and the concave portion 656b is a groove located between the two convex portions 656a, but this is only an example, as long as the convex portion and the concave portion are alternately arranged to form a high friction area.

<Banknote pressing rod> Furthermore, the discharge conveying and accumulating section 500 is provided with a banknote pressing rod (hereinafter referred to as "pressing rod") 670, which is used to decelerate the banknotes that are vigorously discharged from the forming mechanism while pressing them so that they stop (land) at an appropriate position on the surface of the payment tray 700. The rear end (rear part) of the pressing rod 670 is supported by a pressing rod shaft 672 so that it can rotate in the up-and-down direction, so that the part of the pressing rod 670 that is further forward than the rear end, especially the part that protrudes above the payment tray, can rotate in the up-and-down direction. The pressure rod 670, when not discharging banknotes based on the forming mechanism 550, uses its own weight to descend to the upper surface of the payment tray 700 (or the accumulated banknotes). When a banknote with sufficient strength passes through the forming mechanism 550, it is pushed upward by the banknote B to allow the banknote to pass. That is, the frame 660 located above the rotating shaft 552 is provided with a pressure rod shaft 672, and the rear part of the pressure rod 670 can be freely pivoted in the up and down directions by the pressure rod shaft 672, and it descends to the payment tray (on the accumulated banknotes) in an arc manner by its own weight, and is pushed upward by the banknotes when the banknotes are discharged.

The press rod shaft 672 is located behind the rotation shaft 552 (upstream in the conveying direction of the banknotes discharged from the conveying path) and above. The rotation track of the press rod 670 in the up-down direction with the press rod shaft as the center is in an axial position relationship that interferes with the central flange 605. That is, although the width dimension of the press rod has a value that interferes with the central flange 605, an open portion (interference avoidance portion) 673 is formed in the central portion of the width direction of the front end edge of the press rod to avoid interference with the flange 605. That is, the front end edge of the pressure rod 670 becomes a bifurcated branch end 670a, and an open portion 673 for the central flange to enter is formed between the branch ends. Each branch end 670a is composed of a narrow strip-shaped plate, which sandwiches the open portion 673 in the middle and extends in parallel. Due to the formation of the open portion 673, the pressure rod can avoid the central flange 605 and rotate downward over the central flange to move toward the upper surface side of the payment tray 700. The function of the pressure rod 670 is to keep in contact (slide) with the upper surface of the banknote B conveyed along the discharge conveying path 510 during the process of being discharged from the forming mechanism 550, and to apply downward pressure to the banknote by the weight of the pressure rod itself so that it can land stably on the payment tray 700, and to press the banknotes accumulated on the payment tray to prevent them from floating up.

Therefore, the pressing rod in the lowered position must be constructed so that the banknotes with sufficient strength passing through the forming mechanism are well responsive and pushed upward quickly, thereby allowing the banknotes to pass through. On the other hand, the pressing rod must press the accumulated banknotes, so the weight member 675 is fixed to the appropriate position of the front of the pressing rod as needed to add weight. That is, when the pressing rod is not fully pushed upward by the released banknotes, the banknotes cannot reach the regular stop position on the payment tray and will stop at the rear of the payment tray in a buckled state, or collide with the rear of the accumulated banknotes, resulting in the problem of pushing them out. Therefore, the pressure rod must be light enough to be pushed up to a sufficient height by the banknotes, and must be heavy enough to pressurize the upper surface of the accumulated banknotes when it descends to prevent them from floating up.

As will be described later with reference to FIG. 11, the leading end of the banknote B conveyed along the discharge conveying path 510 may contact the lower surface of the pressure rod at a position between the pressure rod shaft 672 and the rotation shaft 552 and begin to be pushed upward. In the discharge conveying path 510, the banknote is deformed into a flat posture and temporarily given a strong force by the clamping force of the conveying guide 510a arranged above and below with a narrow gap and the conveying roller pair 517. Therefore, even if a banknote with rolling marks or weak strength pushes the pressure rod on the upstream side of the rotating shaft 552, the pressure rod can still be pushed up without squeezing, deformation, or buckling. Furthermore, the front end of the banknote that has passed through the forming mechanism 550 is formed into a W shape and given a strong strength, so that the pressure rod can be pushed up and moved forward more strongly and quickly, and landed and stopped at the most appropriate position on the payment tray. The reason why the weight of the pressure rod is generally added by the hammer component 675 is that when the banknote processing device 1 is designed to be shared with different banknotes in various countries around the world, it is necessary to be able to correspond to banknotes of different weights, materials, strengths, etc. That is, the pressing rod has the function of promoting discharge (advance) by pushing the banknotes discharged from the forming mechanism forward, and the function of controlling the landing position by pressing the discharged banknotes. When the weight of the pressing rod is set to a certain value despite the different conditions such as the weight of the banknotes, the pressing rod may be too light or too heavy for the banknotes, and the function of the pressing rod cannot be properly exerted, so the weight adjustment must be performed using a weight. However, based on experiments using the banknote discharge accumulation device M2, it was confirmed that only a 10-gram weight hammer was installed on the pressing rod, and it was possible to correspond to banknotes from all over the world. That is, in this embodiment, it is sufficient to install a weight of a certain weight on the pressing rod, and it is not necessary to adjust the weight according to conditions such as the type of banknote. However, it is also confirmed that regardless of the type of banknote, adjusting the weight of the weight for weak banknotes is effective in normalizing the action of the pressing rod.

<Payment tray> The payment tray (discharge tray) 700 is a means for receiving and accumulating the banknotes discharged (released) from the forming mechanism 550. As shown in the three-dimensional view of FIG2 and the longitudinal section view of FIG8, it is generally provided with: a substantially horizontal flat base surface (first upper surface) 701, an inclined protrusion 703, an indentation member (inclination surface forming member) 705, and an elastic member 707. The inclined protrusion 703 protrudes forward from both ends of the width direction of the base surface near the front end, and has an upward inclined surface (second upper surface) 703a on the upper surface; the retractable member 705 is configured to support the rear end in a narrow groove (hole) 704 provided on the inner edge of each inclined protrusion, so that the front part can be rotated in the up and down direction; the elastic member 707 applies force to the retractable member toward the protruding position shown in Figures 2 and 8. Each of the retractable members 705 always applies force toward the protruding position by means of the elastic member, and the upper surface 705a is inclined more upward than the inclined surface 703a of the inclined protrusion 703, so that the banknotes that want to move forward along the inclined protrusion 703 can be braked to decelerate and stop the banknotes to prevent them from falling. A friction sheet is attached to the upper surface 705a of the retractable member to increase the friction resistance between it and the banknotes. When the friction sheet is not provided, the banknotes released may slide on the resin upper surface 705a due to their force and fly out of the payment tray. The upper surface 705a having a friction sheet and being an inclined surface can effectively decelerate the banknotes. The second and subsequent banknotes can further reduce speed because they can ensure sufficient friction resistance between themselves and the accumulated banknotes.

When a predetermined number of banknotes are discharged and accumulated from the payment tray, when the accumulated banknote bundle is to be taken out, the user can push down the retracting member 705 with a finger to make the upper surface 705a retreat into the groove 704a, so that the retracting member does not hinder the removal of the banknote bundle and makes it easier to remove. Also, when the banknotes are stuck inside the payment tray due to buckling, the user can insert a finger inside by pushing down the retracting member to remove the stuck banknotes.

<Guide member (guide protrusion)> As shown in the figures, guide members (guide protrusions) 710 as protrusions are arranged one by one on the base surface 701 of the payment tray 700 at positions corresponding to (interfering with) the moving trajectory of the blades 654 of each impeller 650. As described later, the guide member works in coordination with the impeller to catch the discharged banknotes B before they move forward and land on the payment tray, and then retreats them to the space 702, thereby eliminating the accumulation (discharge) problem in which the front end of the banknotes protrudes excessively from the front edge of the payment tray. When the length of the payment tray in the discharge direction is shortened, it is conceivable that the banknotes released from the forming mechanism 550 land on the payment tray too far forward and fall from the payment tray. However, the guide member can stop the released banknotes and prevent them from protruding too far forward by cooperating with the blades to move the banknotes backward, thus solving this problem.

As shown in Figures 2 to 5 and 7, each guide member 710 is arranged on the upper surface of the payment tray in a manner that interferes with the moving trajectory of each blade, and by contacting (interfering) with the descending blade, the blade is elastically deformed while allowing it to rotate and move (pass). Each guide member 710 has: a first contact portion (upper surface 716, rear edge 716a) and a curved guide surface 720. The first contact portion contacts the rear of the banknote discharged from the forming mechanism 550 onto the payment tray at a position higher than the upper surface of the payment tray (ahead of the upper surface of the payment tray); the curved guide surface 720 extends downwardly from the first contact portion to the rear (upstream side) of the paper discharge direction. As shown in FIG. 5 and the like, each guide member is set to have its position and width dimension in such a manner as to contact both ends (near) of the width direction of the rear portion of the banknote. In this embodiment, the rear portion of the banknote broadly includes: the rear half of the banknote that can be contacted during the rotation and movement of the blade.

To explain in further detail, as shown in FIG. 7, the guide member 710 generally includes: a front protrusion 715 having a quadrangular and flat upper surface 716, a curved guide surface (guide surface, curved recess) 720 extending continuously downward in a concave shape from the rear edge (corner edge) 716a of the upper surface, and a rear guide surface 722 extending approximately horizontally from the rear edge of the curved guide surface. The rear edge 716a is a corner extending in a straight line parallel to the axial direction of the rotation axis 552. The curved guide surface 720 extends downward and backward in a curved manner with the same width as the rear edge 716a. The rear guide surface 722 extends backward with the same width as the curved guide surface 720. In this example, the rear guide surface 722 is located slightly higher than the first upper surface 701 of the payment tray, but this is only an example. As long as the sweeping effect based on the coordinated action of the blade is not hindered, it can also be set to the same height. Because the upper surface 716 and the rear edge 716a of the upper surface are located at the position where the front end of the rotating blade touches, the front end of the blade can pass through while elastically deforming and touching a part of the upper surface 716 and the rear edge 716a. In order to make it possible to sweep the banknote backward by the coordinated action of the blade, the curved guide surface 720 and the rear guide surface 722 are also selected in a way that the front end of the blade moves while elastically deforming and touching.

Instead of the curved guide surface 720, a guide member connected to a plane inclined downward and backward from the rear edge 716a is arranged on the payment tray. The experimental results show that although the function of sweeping the banknote backward by cooperating with the front end of the blade can be exerted, its sweeping efficiency is not as high as that of the curved guide surface. As shown in Figure 5(a), the width of each guide member is more than twice the width of the blade, and it extends outward in the axial direction beyond each outer flange 607, 609 in a manner that can contact the two ends of the width direction of the banknote B. In this way, it can contact the two ends of the width direction of a wide banknote and guide it.

<Change withdrawal operation procedure> Figure 9 is a flowchart illustrating the outline of the change withdrawal operation procedure of the banknote processing device 1 of the present invention. When the receipt of the received money and the withdrawal of the change are confirmed, the withdrawal of the change is performed according to the following procedure.

First, the control means 1000 instructs each circulation unit 30, 40 to withdraw a predetermined number of banknotes of the stored denominations (step S1). For example, the control means 1000 instructs that three 1,000-yen bills stored in the circulation unit 30 and one 5,000-yen bill stored in the circulation unit 40 be withdrawn as change onto the payment tray. In this way, each circulation unit 30, 40 starts withdrawing the designated number of 1,000-yen bills and 5,000-yen bills (step S3). For example, after three 1,000-yen bills are withdrawn continuously from the circulation unit 30, one 5,000-yen bill is withdrawn from the circulation unit 40. The banknotes discharged one by one from each recycling unit 30, 40 are checked for denomination by the identification unit 70 provided in the banknote storage conveying path 9b. If they are of the specified denomination, they are sequentially fed into the discharge conveying and accumulation unit 500, and the discharge conveying of each banknote is started (S5, S7 yes, S9). In step S7, if it is determined that the banknotes are not returnable, they are temporarily retained in the custody department and then conveyed to the recovery warehouse 50 (step S21). In step S11, if the paper sensor 580 detects that the banknotes B fed into the discharge conveying and accumulating section 500 have passed through the forming mechanism 550 (step S11 is yes), in step S13, it is determined whether there are subsequent banknotes. If there are subsequent banknotes, the subsequent banknotes are continuously discharged by the discharge conveying mechanism 520 (step S15). Furthermore, in step S17, it is checked whether all subsequent banknotes have passed through the forming mechanism. If they have passed, the processing is terminated.

"Comparison with the previous banknote processing device" Next, in order to make the advantages of the present invention clearer through comparison with the known example, the side longitudinal section of the previous discharge conveying and accumulation section 500P shown in Figure 10 is used for comparison and explanation. The previous discharge conveying and accumulation section 500P has: a discharge conveying path 510P, a discharge conveying mechanism 520P, a pressure rod 670P, a payment tray 700P, and a discharge mechanism (driving roller 600P, tension roller 601P) for discharging banknotes onto the payment tray. In addition, the discharge mechanism does not have the function of deforming the short side shape of the banknote in a predetermined manner to correct the curling mark. Furthermore, the conventional pressing rod 670P has a pressing rod shaft 672P located closer to the payment tray side (in front) than the driving roller shaft 552P, and the total length of the pressing rod is necessarily shorter than the pressing rod of the present invention. Therefore, the timing when the banknote B conveyed along the discharge conveying path 510P contacts the pressing rod 670P and starts to push the pressing rod upward is after the front end thereof passes through the discharge mechanism and contacts the pressing rod. The discharge mechanism does not have the function of strengthening the strength of the short side of the banknote. Therefore, when the strength of the banknote is weak or there is a curling mark with the front end of the banknote tilted downward, the pressure rod cannot be pushed up sufficiently, and the banknote may be bent and stuck. In other words, when the banknote does not push the pressure rod up sufficiently, the banknote cannot move forward sufficiently on the payment tray and may stop in a bent state at a position far inward (right direction in the figure) from the regular stop position on the payment tray. Therefore, it is difficult to accumulate multiple banknotes discharged in sequence on the payment tray in a state that is easy to remove and well aligned.

In the conventional discharge conveying and accumulating section 500P, the banknote discharged from the discharge mechanism contacts the lower surface of the pressing rod 670P at a position (contact point C) that is further forward than the rotation axis 552P and very close to the pressing rod axis (see FIG. 10). As a result, the distance L3' between the pressing rod axis 672P and the contact point C between the pressing rod and the front end of the banknote becomes shorter, and the banknote requires a large force to lift the pressing rod. Therefore, the weak banknote cannot fully push the pressing rod upward, and becomes easy to buckle at a position further back than the normal stop position. In particular, when the front end of the banknote reaches the contact point C, it is freed from the restraint caused by the conveying roller 517P, the driving roller 552P, and the tension roller 601P and returns to a weak state, and the front end of the banknote is easily bent downward as shown in Figure 10. After that, the rear part of the same banknote that is discharged by sequentially freeing itself from the restraint of each roller also becomes easy to bend continuously.

Furthermore, the conventional pressure rod 670P requires a greater force to push the pressure rod upward because the initial angle θ' when it descends becomes smaller. Therefore, the weak banknotes cannot fully push the pressure rod upward, and are prone to buckling after being discharged. Or, they are prone to collide with the rear of the accumulated banknotes, pushing them out of the payment tray and causing them to fall. In contrast, in this embodiment, the pressure rod shaft 672 is located further back than the rotation shaft 552, and the pressure rod 670 is elongated. The length of the pressing rod 670 is set so that when there are no banknotes on the payment tray, the front end of the pressing rod can be lowered to a suitable position on the upper surface of the payment tray (in this example, the base surface 701) to make contact. This is because if there is a gap between the front end of the pressing rod and the upper surface 701 of the payment tray, the banknotes may drill through the gap and fly out of the payment tray.

In this embodiment, the distance L3 between the pressure rod shaft and the contact point C between the pressure rod and the banknote (see Figure 11 (a)) can be made sufficiently long. Therefore, the force required for the banknote to lift the pressure rod is smaller, making it easier to push the pressure rod upward. Because the contact point C is located in the discharge conveying path 510 (near the forming mechanism), the conveying guide 510a and the conveying roller pair 517 flatten the front end of the banknote when it reaches the contact point C, and the force is temporarily strengthened, so that the pressure rod can be pushed upward efficiently. The structure is such that when the elongated pressure rod 670 descends, its front end contacts the upper surface 701 of the payment tray, so that the initial angle θ' when the pressure rod descends as shown in Figure 11 (a) can be increased, making it easier to push up when the banknotes rush in. Therefore, even if the banknotes are weak, the pressure rod can still be pushed up efficiently.

In this embodiment, in order to solve the problem that the banknotes released onto the payment tray cannot fully push the pressure rod upward, that is, the pressure rod cannot resist the weight and falls (roll marks upward in the long side direction), the following three points are worked on. That is, (1) the short side shape of the banknote is formed into a predetermined shape (such as a W shape) that can strengthen the strength of the banknote along the long side by the forming mechanism 550; (2) the weight of the pressure rod is adjusted to the optimal value by using the hammer member 675; (3) the width W1 of the central flange 605 is set to be sufficiently wide to maintain the lifting effect of the pressure rod based on the banknote.

First, regarding (1), in order to form the banknote into a W-shape over the entire length, it is preferred that the banknote does not fall but continues to maintain a horizontal or upward posture until the rear end of the banknote passes through the forming mechanism 550 (the clamping portion n1 of the drive roller and the tension roller, and the flange), and such a function can be fully exerted according to the forming mechanism. That is, the banknote discharged from the forming mechanism onto the payment tray 700 can be discharged while pushing the pressing rod 670 upward due to the increased strength. That is, when the banknote passes through the forming mechanism, it is clamped by the ridges and the final roller pair, and the banknote protruding from the front of the forming mechanism can continue to maintain the corrected rolling mark (strength enhancement). When the banknote passes through the forming mechanism, it can also maintain the corrected rolling mark and fall at the correct position, and finally the banknote can be compressed together with the accumulated banknotes by the pressure rod.

Next, regarding (2), it has been considered that the banknote discharge accumulation device M2 is a general-purpose machine that can correspond to banknotes of various countries in the world. That is, banknotes of various countries have different materials, thicknesses, strengths, weights, sizes, etc. In order to improve the accumulation property in accordance with these differences, the weight of the pressure rod must be adjusted. In other words, with respect to the weight of the banknotes, if the pressure rod is too light, the effect of pressing the accumulated banknotes on the payment tray when descending is reduced. On the other hand, if the pressure rod is too heavy, the discharged banknotes may be excessively pressed downward. Therefore, the weight of the pressure rod must be finely adjusted using the hammer component 675.

Next, regarding (3), in order to prevent the corresponding part of the banknote from being trapped in the gap G2 between the open part 673 formed between the divergent ends 670a of the pressure rod and the central flange 605, the width W1 (Figure 3) of the central flange is set to be sufficiently large. This is because if the banknote enters and is trapped in the gap G2, the effect of pushing the pressure rod upward is reduced, and there is a possibility of causing buckling on the payment tray. This point will be described later. In the previous device structure, there was no such consideration at all.

"Processing procedure for discharged banknotes based on the discharge conveying and accumulating section" Next, the processing procedure for discharged banknotes based on the discharge conveying and accumulating section 500 (forming mechanism, impeller, banknote pressing rod and guide member) is explained with reference to FIGS. 11 to 14. On the rotating shaft 552, the base portion 652, which becomes the center portion of the impeller 650, is integrated so that it rotates integrally with each drive roller 555, 600 and each flange 605, 607, 609. The function of the conventional impeller is to knock down the discharged banknote B with the blades, thereby preventing the banknote from flying forward from the payment tray. In contrast, the impeller of this embodiment, in addition to the previous functions, can also play the following function, that is, in the process of the discharged banknotes falling one by one, it can move the banknotes to the rear by cooperating with the guide member 710 provided on the payment tray.

Figures 11(a) to (d) are operation diagrams (lateral longitudinal cross-sectional views) of the discharge conveying and accumulating section 500, showing the state from the front end of the banknote just passing through the forming mechanism 550. After the front end of the banknote B conveyed in the discharge direction in the discharge conveying path 510 contacts the pressing rod, it passes through the forming mechanism while pushing the pressing rod upward. Figures 12(e) and (f) are operation diagrams (lateral longitudinal section diagrams) of the discharge conveying and accumulation section 500 showing the state before the rear end of the banknote B passes through the forming mechanism and the state just after passing through. Figures 12(g) and (h), Figures 13(i) to (l), and Figures 14(m) to (O) are operation diagrams showing the process from the banknote falling on the payment tray to the blade moving the banknote backward. The shape of the discharged banknote B shown in each figure only shows the shape of the end face after the banknote is cut at the center of the short side. In other words, the state and movement trajectory of the cut end face of the banknote corresponding to the center of the short side (protrusion P1) corresponding to the center ridge 605 are shown. Therefore, the short side parts (protrusions P2, P3) corresponding to each drive roller 555, 600 and the outer flanges 607, 609, as well as the state and movement trajectory of each oblique side S1, S2 are not shown.

The withdrawn banknotes before entering the forming mechanism 550 are flattened by being pressed from top and bottom by the conveying roller (conveying member) 517 etc. in the discharge conveying path, and after passing through the forming mechanism, the short side shape is formed into a W shape along the long side direction as shown in FIG. 6 (given a characteristic). Therefore, the shape of the banknote located downstream of the forming mechanism is actually three-dimensionalized into a W shape. As described above, in FIG. 11 to FIG. 14, because the cross-sectional view of the short side center of the banknote is cut across the entire length, the difference in the shape (upper and lower thickness) of the banknote before and after passing through the forming mechanism is not presented. The pressure rod 670 is constructed so that the pressure rod shaft 672 is located further back than the rotation shaft 552 and does not interfere with the central flange 605, so that the front end of the pressure rod can move up and down, thereby making the following actions possible.

In Fig. 11(a), the banknote B discharged from any circulation unit and transported upward along the storage banknote transport path 9b is guided to the discharge transport path 510 by rotating and driving the roller 512a in the counterclockwise direction and by the coordinated action of the roller 512a and the tongue valve 514 in the switching position shown in the figure. In Fig. 11(a), at the position just in front of the forming mechanism 550, that is, at the position just in front of the clamping part n1 of each driving roller 555, 600 and each driven roller 556, 601, the front end of the banknote contacts the lower surface of the pressing rod 670 and starts to press it. That is, when the banknote has not reached the forming mechanism, as shown in FIG11(a), the pressure rod 670 is lowered by its own weight and its front end contacts the upper surface of the payment tray 700, and as shown in FIG11(b), the banknote pushes the portion (contact point C) at a distance L3 from the pressure rod shaft 672 to push the pressure rod upward. Since the pressure rod shaft 672 is located further behind the rotation axis 552, the front end of the banknote can contact the pressure rod at the position of FIG11(a) (a position further upstream than the rotation axis) and start to be pushed upward. Furthermore, since a sufficiently long distance L3 is ensured between the press rod axis and the contact point C, and the initial angle θ of the press rod is large and close to 180 degrees, the press rod can be pushed up with a small force.

In FIG. 11(c), the distance that the banknote B moves in the discharge direction is slightly forward compared to FIG. 11(b). The banknote pushes the pressure rod and pushes it further upward, but it has not yet reached the lower surface of the frame 660 located above. At this stage, the front end of the banknote has not completely passed through the forming mechanism. When the banknote passes through the forming mechanism, the central part of its short side moves along the upper part of the central flange 605, and the short side parts corresponding to each driving roller 555, 660 pass through the clamping part n1 of the tension roller 556, 601, and the short side parts corresponding to each outer flange 607, 609 move along the upper part of each outer flange. The timing of the movement of each short side part in the corresponding part is roughly the same. The banknote passes through the forming mechanism, which means that the short sides of the banknote are completely separated from the central ridge 605, the clamping part n1 of the drive roller and the tension roller (the final roller pair), and the outer ridges.

Next, in the stage of FIG. 11( d ), the banknote is still clamped and held (clamped) by the convex edge and the final roller constituting the forming mechanism, and the front end of the banknote passes through the forming mechanism and slightly moves forward, and the short side shape of the completed portion is formed into a W shape. Therefore, the front end of the banknote located on the downstream side of the forming mechanism is in a state of being given a strong force, and the front end of the banknote with a strong force pushes the pressing rod upward to a position where it contacts the frame 660, and the pressing rod stops rising. At this time, the portion of the banknote located downstream of the forming mechanism will not push the pressing rod, so the posture of the portion of the banknote will not tilt downward or bend, but will maintain a horizontal posture or an upward tilted posture.

In Fig. 12(e), the front part of the banknote, except for the rear part clamped by the clamping parts n1 of each driving roller and each driven roller, is given a strong force by the forming mechanism, and as shown in the figure, the pressing rod is continuously pushed upward to the most raised position while maintaining a substantially straight posture. That is, the banknote is discharged along the lower surface of the pressing rod in the most raised position, and at this stage, the front end of the banknote has not yet dropped onto the payment tray.

FIG12(f) shows a state where the rear end of the banknote B is completely separated from the forming mechanism 550. Even if the banknote originally has a rolling mark with the front end tilted downward, the rolling mark is removed at the stage of being discharged from the forming mechanism toward the payment tray. Therefore, the banknote discharged onto the payment tray will not push out the accumulated banknotes and cause them to fall from the payment tray. That is, in the process of FIG12(e) to (f), the front end of the subsequent banknote will not contact the rear or other parts of the accumulated banknotes and push them out of the payment tray.

The accumulated banknotes are also formed by the forming mechanism to remove the curling marks, and can maintain a straight and flat posture throughout the entire length, so there will be no unnecessary interference with the subsequent banknotes. Next, in the stage of Figure 12 (g) and (h), the front end of the banknote protrudes from the front end of the payment tray. If this state is left unchecked, it may fall off the payment tray. When the front-to-back length of the second unit M2 is required to be shortened, the front-to-back length of the payment tray is shortened, so this phenomenon becomes easy to occur. In this case, when the banknotes released after being formed by the forming mechanism land on the payment tray while being pressed by the pressing rod, the front end thereof will protrude significantly from the front edge of the shortened payment tray and become easy to fall. In order to solve this problem, the present invention is configured such that, as shown in Fig. 12 (g) and (h), a space 702 for retreat is formed at the rear of the payment tray 700 at the time when the banknotes land in a state of protruding significantly from the front edge of the payment tray (in this case, the emergence member 705). Furthermore, on the upper surface of the payment tray corresponding to the space 702 for retreat, a guide member 710 as a protrusion is fixedly arranged at a position corresponding to the moving trajectory of the blades 654 of each impeller. By the coordinated operation of the guide member and the impeller, the banknote B discharged onto the payment tray is allowed to retreat toward the space 702, thereby eliminating the state where the front end protrudes from the front edge of the payment tray. The configuration and height structure of the guide member 710 are such that, as shown in Figures 12(g) and (h), the sweeping based on the blade begins at the stage in which the rear part of the banknote dropped onto the payment tray is in the air before it drops to the upper surface 716 or the rear edge 716a of the guide member. That is, the first contact between the falling banknote and the blade is made when the banknote is in the air. Because the behavior of banknotes is not consistent, when the back of the banknote falls to the upper surface of the guide member, or while falling, the front end of the blade may also contact the back of the banknote. It has been confirmed that even in this case, the banknote can still be swept backward without any problem. The length and position relationship of each blade 654 is set so that it will slide with the outer surface of the guide member 710 during the rotational movement.

The rotation speed of the impeller, the rotation timing of the blade for discharging banknotes, and the length of the blade (the rotation track of the front end of the blade) are selected so that the blade 654c rotating from above can capture the rear of the banknote discharged onto the payment tray and pull it down toward the guide member 710, as shown in Figures 12(g), (h), and 13(i), (j). The front-to-back position of the guide member on the payment tray, the front-to-back length of the upper surface 716, and the front-to-back position of the rear edge 716a are selected so that the rear lower surface of the banknote pulled down by the blade 654c can easily contact the upper surface and rear edge of the guide member as shown in the above figures. By adopting such a structure, even if the discharged banknotes want to fly forward too much, the blade 654c can capture the rear end of the banknote in the air at the early stage of the banknote discharge and start to sweep downward and backward. Furthermore, when the blade 654c reaches the rear edge 716a of the guide member, it can start to clamp the lower surface of the rear part of the banknote between it and the rear edge, and then move the entire banknote backward while clamping it between the front end of the blade and the curved guide surface 720 (Figure 13 (k) (l), Figure 14 (m) to (O)). In the stage after Figure 12(g), because the banknote whose rear end has separated from the forming mechanism 550 is being pressed down by the pressure rod 670 while descending, the coordinated action of the pressure rod and the blades can move the banknote backward while descending.

To further explain in detail, in the present invention, in order to increase the processing speed of the discharged banknotes, before the banknotes discharged from the forming mechanism 550 fall completely onto the upper surface of the payment tray or the guide member 710, at the stage where the rear part of the banknote is in the air (Figure 12 (g), (h)), the front end of the blade 654c is brought into contact with the rear part of the banknote. In this way, by appropriately selecting and setting the contact timing of each blade with each banknote, in other words, the rotation speed of each blade and the release speed of each banknote, the action of forcibly pulling the banknote in the downward direction and backward can be started at the point in time when the rear part of the banknote in the air contacts the blade. Then, when the blade descends to the position where it contacts the upper surface and the rear edge of the guide member, the rear of the banknote is sandwiched between the blade and the guide member, and the banknote can be reliably moved backward along the curved guide surface 720 by the subsequent rotation of the blade. Therefore, all banknotes, regardless of the difference in the length direction, can be accumulated on the payment tray with the rear ends aligned, without falling from the front edge of the payment tray. In this embodiment, as shown in Figures 12(g) to 14(O), the banknotes discharged onto the payment tray are pulled backward once the front end lands on the payment tray (on the entry and exit member 705). If this phenomenon is observed from the return port side, the banknote is discharged in a state where it protrudes from the front edge of the payment tray, and then is pulled backward and stops. The falling path and falling timing of the banknote with enhanced strength are relatively stable and constant by the forming mechanism 550, but in the case of banknotes with very strong upward curling marks or so-called wrinkled banknotes whose strength is significantly reduced, the falling path and falling timing may still be inconsistent even after being formed by the forming mechanism. Therefore, the blades may not always be able to capture the rear of the banknote at the same time in the air. It is also possible that the rear of the banknote falls onto the guide member before contacting the blades. However, according to this embodiment, even in such a case, the blade can still clamp the rear of the banknote between it and the guide member and sweep it backward.

To further explain in detail, the structure and rotation timing of the impeller are set to knock the released banknotes downward. In particular, in the present embodiment, the banknotes released by the forming mechanism 550 are formed into a W-shape with short sides, and as long as the curling marks before forming are of a normal level, they can contact the blades in the air during the falling process. However, when the upward curling marks of the banknote in the long side direction are extremely strong, the forming mechanism cannot form the banknote into a complete W-shape over the entire length of the banknote, and therefore, sufficient force may not be given. In such a case, the curling marks may be restored at the moment when the banknote leaves the forming mechanism, so that the rear end of the banknote is curled into a shape that avoids the blade, and the rear part of the banknote falls onto the guide member 710 before contacting the blade. However, according to the structure of this embodiment, even in such a case, the rear part of the banknote is hooked by the guide member to prevent it from moving forward, and is captured by the front end of the blade that descends subsequently and swept backward. As a result, the banknote can be prevented from falling off the payment tray. The same treatment can be performed on wrinkled banknotes with significantly reduced strength.

Next, the following further describes the structure and function of the impeller 650, the pressure rod 670, and the guide member 710, etc., in the process of pressing the banknote discharged from the forming mechanism 550 downward by the pressure rod, and the action of moving the impeller backward. As shown in FIG. 12 (g) and (h), when the rear of the banknote B discharged from the forming mechanism 550 onto the payment tray is still in the air, if the blade 654c rotating downward contacts the rear of the banknote, the high friction area 656 can reliably capture the banknote, and cooperate with the downward pressing action of the pressure rod to start the action of forced downward and rearward sweeping. That is, the banknotes discharged from the forming mechanism are forced forward and tend to move toward the front edge of the payment tray 700 in the air. In contrast, the blade 654c moving downward contacts the rear of the banknote in the air, thereby weakening the force of the banknote to move forward and stopping it from moving forward, and then guiding it in the direction of the rotation of the blade 654c (downward and backward). In the configuration example shown in the illustrated embodiment, a new type of press rod 670 is used in which the press rod shaft 672 is arranged in the discharge conveying path 510 upstream of the forming mechanism. However, this is only an example, and a conventional press rod (Figure 10) in which the press rod shaft is arranged outside the terminal end of the discharge conveying path, that is, above the payment tray, can also be used. That is, in the discharge conveying accumulation section having the conventional press rod, by using the impeller and the guide member 710, the sweeping effect of the banknotes can be obtained.

In FIG. 12(g)(h), if the blade 654c captures the rear of the banknote B in the air and continues to rotate downward, the blade 654c will press the rear of the banknote downward until it contacts the upper surface 716 and the rear edge 716a of the guide member 710. At this point, the rear of the banknote is clamped and held between the high friction area 656 and the rear edge 716a. Therefore, by further rotating the blade, the banknote moves backward along the curved guide surface 720 and the rear guide surface 722 as shown in FIG. 13 and FIG. 14 in sequence. At the time point of FIG. 14 (O), the blade 654c is roughly separated from the rear end of the banknote, and the movement of the banknote to the rear stops. If necessary, a stopper for aligning the rear ends of each banknote swept backward can also be set at the end of the space 702 for retreat. As described above, before the rear end of the banknote discharged from the forming mechanism falls to (contacts) the upper surface 716 of the guide member, the blade 654c contacts the rear end of the banknote at a position further forward and above the upper surface 716, and starts to sweep it downward and backward (in the opposite direction of the banknote discharge direction). In other words, the contact position C between the front end of the blade and the banknote can be set at a farther position on the rotation track of the front end of the blade. Therefore, the banknote can be pulled backward at an early stage before the banknote lands on the payment tray, and the banknote accumulation processing speed can be accelerated.

Furthermore, by providing the guide member 710, when the rear of the banknote on the way down is located at a position higher than the upper surface 701 of the payment tray, it can contact the rear edge 716a of the guide member. That is, the rear of the banknote can be hooked by the rear edge 716a before the rear of the banknote lands on the payment tray. Therefore, the banknote that once lands on the payment tray in a state of flying out from the front edge of the payment tray can be quickly pulled backwards and stopped at the most appropriate position. According to the above structure, regardless of the size of the long side of the banknotes, the rear ends of all banknotes discharged onto the payment tray can be aligned in order, thereby preventing the banknotes from excessively protruding or falling from the front edge of the payment tray, and making the multiple banknotes accumulated on the payment tray the most suitable state for users to take out in batches. There is also a strong demand for miniaturizing and shortening the payment tray as much as possible, because the discharged banknotes can be aligned with the rear ends based on the inside of the payment tray, and such a demand can be met.

Next, the present invention will be described in more detail with respect to the structure and operation of pulling (sweeping) the banknotes backwards based on the guide member and the impeller, while comparing it with the structure and operation of the conventional impeller. In the past, the impeller used to press the banknotes released onto the payment tray pressed the banknotes onto the payment tray by the downward rotating blades, thereby suppressing the banknotes from flying forward. That is, the conventional blades only had a pressing function in order to prevent the released banknotes from floating up and flying forward, and pressed the banknotes after the banknotes landed on the upper surface of the payment tray or before they landed. Furthermore, after the tip of the blade contacts the top surface of the payment tray with the banknote sandwiched in the middle, it begins to rotate and move backward while elastically deforming. Since the top surface of the payment tray is a flat surface, even if the tip of the blade moves backward, it still cannot move the banknote in the same direction. In other words, the conventional impeller only moves backward while sliding on the top surface of the banknote between the tip of the blade and the top surface of the payment tray after the tip of the blade contacts the banknote, and does not have the function of moving the banknote on the payment tray backward.

In contrast, in this embodiment, when the banknote is released from the forming mechanism 550, the front end of the blade contacts the rear end of the banknote at a sufficiently early time before the banknote lands on the upper surface of the payment tray, that is, at an appropriate early time just after the release, and the banknote begins to decelerate and change direction. Then, the banknote continues to fall backward until the back of the banknote portion that contacts the front end of the blade contacts the upper surface or rear edge of the guide member (located at a higher position than the upper surface of the payment tray). After the banknote is clamped between the front end of the blade and the front protrusion 715 of the guide member, the entire banknote can be smoothly moved downward and backward along the curved guide surface 720. The front end of the blade begins to deform elastically while clamping the banknote between it and the hard guide member 710. In the process that the front end of the banknote deforms elastically while moving to the curved guide surface 720 and the rear guide surface 722 in sequence through the rear edge 716a of the guide member, the front end of the blade deforms elastically to follow the shape of each part of the guide member while increasing the contact area with the banknote surface (no slippage occurs between it and the banknote), thereby ensuring a longer contact and scanning time. That is, the area where the front end of the blade contacts the banknote is increased and the pressure contact force is increased, so the sweeping force is increased, and there is no slippage between the blade and the banknote, and reliable sweeping can be performed.

In addition, the impeller in the past did not have the effect of pulling the released banknotes in the opposite direction of the release direction, and there was no idea to make the effect of pulling in the opposite direction by the blades work. In contrast, in the present invention, by setting the guide member having an upper surface higher than the upper surface of the payment tray at a position interfering with the blades, a reliable pulling effect can be achieved by using the coordinated action of the guide member and the blades. In addition, the falling position of the banknotes released from the clamping part n1 of the drive roller and the tension roller to the payment tray may be inconsistent in the front and rear directions depending on the strength of the rolling marks of the banknotes. In the present invention, the impeller blades can capture the banknotes that are about to fall in the air at a farther distance, and then sweep them in the opposite direction of the release direction by cooperating with the guide member. When there is no guide member, because the banknotes are pressed by the blades on the flat upper surface of the payment tray, even if the force that presses the banknotes downwards (the force that stops the banknotes) can be exerted, it still cannot generate a force to pull them backwards.

In particular, the guide member of this embodiment has a curved guide surface 720 which is connected to the rear edge of the upper surface and descends in a curved manner from the front upper side to the rear lower side. Since the curved surface is roughly consistent with the rotation trajectory of the blade, it is possible to allow the banknote to slide backward while sweeping. The curved shape of the curved guide surface 720 is configured to overlap with the circular trajectory of the front end of the blade drawn with the rotation axis 552 as the center. In addition, the curvature radius of the curved guide surface is smaller than the curvature radius of the circle drawn by the front end of the blade. However, the curved guide surface may not be in an arc shape, as long as it can be in a curved shape that can smoothly guide the rear of the banknote while clamping it between the front end of the blade. In addition, by setting the friction resistance of the surface of the guide member 710 that contacts the banknote to be smaller (smaller than the friction resistance between the surface of the payment tray), the sliding between the banknote and the guide member can be improved, making the movement to the rear smoother. In the second unit (banknote discharge and accumulation device, batch exit unit) M2 equipped with the forming mechanism 550, the banknotes to be released onto the payment tray are formed in such a way that the strength is strengthened and the left and right ends of the short sides are tilted upward. Even if the guide member 710 does not exist, subsequent bent banknotes can be prevented from causing the accumulated banknotes to fall and the bent banknotes themselves to fall from the payment tray. Therefore, when a forming mechanism is provided, the guide member is not a necessary component for preventing bent banknotes from falling from the payment tray.

However, the coordinated action of the guide member and the blades on the banknotes is useful in improving the alignment of the banknotes on the payment tray and preventing them from falling. The rear of the accumulated banknotes is pressed between the blades of the impeller that rotates continuously and the guide member, which is also the main reason for solving the problem of subsequent banknotes pushing out the accumulated banknotes. As an advantage of the forming mechanism 550 of the above-mentioned embodiment, although the correction of banknotes with upward rolling marks is explained, of course, the forming mechanism also has the function of correcting downward rolling marks of banknotes.

"Countermeasures for weak banknotes" Next, when the forming mechanism 550 is not provided in the discharge conveying and accumulating section 500, that is, when the flanges 605, 607, 609 are not provided, the weak banknotes are discharged from the clamping section n1 of the final roller pair (driving rollers 555, 600 and tension rollers 556, 601) to the payment tray. In such a configuration, the weak banknotes after discharge move forward only by their own strength, and must be lowered to the payment tray while lifting the pressure rod 670 with the strength. The banknotes with a force below a predetermined level are squeezed and deformed by the pressing rod and cannot pass through the pressing rod to move forward. That is, when the banknotes with a force below a predetermined level are conveyed along the discharge conveying path 510, regardless of whether they have curl marks, if the flanges 605, 607, 609 are not present, the banknotes cannot fully push the pressing rod 670 upwards and land at a proper position on the payment tray during the discharge process onto the payment tray 700. In other words, during the discharge process, because the pressing rod cannot be fully raised and remains in a low position, the banknotes cannot pass through the pressing rod and move forward, and are squeezed and deformed by the pressing rod. Therefore, weak banknotes are prone to buckling in the narrow space between the lower surface of the pressing rod that is kept down and the upper surface of the payment tray. When multiple banknotes are discharged as change, even if there is only one banknote with reduced strength, it will cause poor discharge and alignment of subsequent banknotes.

In this embodiment, the strength of the banknote whose strength is reduced to below a predetermined level can be strengthened by the forming mechanism 550, thereby solving the above-mentioned problem. Furthermore, as described above, the pressure rod shaft 672 is arranged on the upstream side of the driving shaft (rotation shaft) 552 of the final roller pair, and the conveying roller 517 conveys the banknote in the travel direction with great force, so that even a banknote with very weak strength can be strongly pushed up. In addition, the weight of the pressure rod 670 and the initial angle of the pressure rod (the tilt angle at the lowest descent) are also set to be able to lift the banknote whose strength is reduced to below a predetermined level. As an example, the weight of the plunger excluding the weight hammer member 675 is about 10 g, and the initial angle θ is about 21°.

[Banknote discharging and conveying device: second embodiment] According to the banknote discharging and accumulating device M2 of the second embodiment, even if the banknote is severely deteriorated (wrinkled banknote), the banknote can be formed into a desired shape by the forming mechanism 550 to strengthen the strength and be discharged and accumulated in a normal state on the payment tray. When the strength of the discharged banknote B is severely reduced, that is, the banknote is wrinkled, even if the short side shape of the banknote is formed into a predetermined shape by the forming mechanism 550, the strength cannot be fully strengthened to the level of a normal banknote with sufficient strength.

FIG. 15 is a comparative example showing a configuration example in which the gap G2 of the banknote discharge accumulation device is enlarged, and is a partial cross-sectional front view showing a state in which a banknote with significantly reduced strength passes through a forming mechanism in which the gap G2 is set to be too large. When a banknote with significantly reduced strength passes through the forming mechanism 550, if the interval (gap G2) between the open portion 673 between the divergent ends 670a at the front end of the pressing rod and the central flange 605 is too large, in other words, if the flange width W1 is too small relative to the width W3 of the open portion 673 and the gap G2 is enlarged, as shown in the figure, it becomes difficult to let a part of the banknote sink (bite) into the gap G2 and push the pressing rod upward. That is, the banknote with significantly reduced strength has a tendency to deform the front edge portion corresponding to the gap G2 and enter the gap before the pressure rod is pushed up. Furthermore, as the banknote moves forward, the following portion also deforms immediately after the front end and enters the gap G2. Therefore, the strength of the portion that has entered the gap G2 is reduced, which reduces the force (strength) that pushes the pressure rod up.

As a specific numerical value, imagine that a wrinkled banknote is sunk into the gap G2 at a depth of about 2.5 mm. Because of the sunken portion, the height position of the pressure rod on the rotating shaft 552 is lowered by 2.5 mm. In this way, the angle of the pressure rod becomes about 7.5 degrees downward corresponding to the amount of reduction. In other words, if the banknote does not enter the gap at a depth of 2.5 mm, the angle of the pressure rod will become the original upward position of 7.5 degrees. If the banknote cannot fully push the pressure rod upward and the angle of the pressure rod is lowered, the banknote will bend when it contacts the upper surface of the payment tray, which increases the risk of jamming. If the relationship between the central flange 605 and the driving roller 555 shown in FIG15 is explained, the shorter the distance between the corner 605a of the upper part of the central flange and the corner 555a of the upper part of the driving roller, the stronger the force (strength) of holding the portion of the banknote located between the corners. Compared with the distance between the corner 605a of the central flange 605 and the corner 555a of the driving roller 555 in the first embodiment shown in FIG3, the distance between the corresponding portions in FIG15 is much longer. Therefore, in the configuration example of FIG15, the banknote can easily enter the gap G2. If the banknote enters the gap G2, the banknote will become curved, and the angle of the pressure rod will be reduced according to the amount of banknote entering the gap. The above description can also be applied to the relationship between the central flange 605 and the other driving roller 600.

<Discharge conveying and accumulating section> In order to cope with such a problem, the relationship between the opening portion 673 at the front end of the pressing rod and the central flange 605 is optimized in the discharge conveying and accumulating section 500. The other characteristic structures of the discharge conveying and accumulating section 500 are described below with reference to FIGS. 3 to 5. The forming mechanism 550 sets the ratio of the width W1 of the central flange to the width W3 of the opening portion so as to prevent a part of the severely deteriorated banknote from being sunk into the gap G2 formed between the two inner edges of the opening portion 673 of the pressing rod and the outer side surface of the central flange 605. In conjunction with the W-shaped forming performed by the forming mechanism 550, the central convex edge is widened to appropriately narrow the gap G2. Even if the banknote is wrinkled, the strength can still be increased to a level that can fully push the pressing rod upward to improve the accumulation, and the banknote can be discharged in an upward posture.

As an example of the actual device configuration, when the width dimension W1 of the central rim is set to 6.0mm and the width dimension W3 of the open portion 673 of the pressure rod is set to 9.2mm, the wrinkled banknotes can be prevented from sinking and the effect of preventing the banknotes from buckling can be fully exerted. According to experiments, the optimal value of the ratio of the width dimension W1 of the central rim to the width dimension W3 of the open portion is about 0.65. In the above-mentioned dimension example, the left and right gap G2 values are 1.6mm respectively. In this way, in the present invention, the width W3 of the open part of the pressing rod is kept constant, and the width W1 of the central ridge is set to be larger than the width of the outer ridge to appropriately reduce the gap G2, thereby preventing the banknote from sinking. Therefore, even if it is a wrinkled banknote with significantly reduced strength, the outer peripheral surface of the central ridge can be pushed up to improve the shape retention (strength), and the pressing rod can be raised. In other words, by adjusting the size of the above-mentioned gap, the backup function based on the wide outer peripheral surface of the central ridge is improved, and a state can be achieved in which the strength of the wrinkled banknote exceeds the weight of the pressing rod.

In the case where a 20-gram weight hammer member 675 is fixed to the front end of the pressure rod, the banknote must lift the pressure rod containing the weight, because the pressure rod shaft 672 is located behind the rotation axis 552, and the pressure rod can be lifted by the back support based on the central flange. According to the above description, a banknote with significantly reduced strength, that is, a wrinkled banknote, can be defined as a banknote that is weakened to the extent that a portion of the banknote is sunk into the gap G2 between the two when the ratio of the width W1 of the central flange to the width W3 of the open portion of the front end of the pressure rod is less than a predetermined value (e.g., about 0.65). That is, even if the fragility (strength reduction) of the banknote progresses, as long as the fragility is such that a part of the banknote does not fall into the excessive gap G2, the strength can be sufficiently enhanced by forming the banknote into a W shape, so that a part of the banknote will not fall into the gap G2 even if it is too large. Moreover, even if the banknote is so fragile that a part of the banknote falls into the excessive gap G2, as long as the ratio of the width W1 of the central ridge to the width W3 of the open portion at the front end of the pressure rod is set in such a way that G2 becomes an appropriate value (for example, about 0.65 or more), the banknote can be discharged while the pressure rod is pushed upward by utilizing the strength enhancement effect based on forming into a W shape and the back-supporting effect of the banknote based on the central ridge. When formed into an M shape, the wide bills are prone to drooping because their two ends are tilted downward, and are prone to collide with the accumulated bills. Especially for bills with very long short sides, even if the central part and the two outer parts are clamped tightly by the central ridge and the roller pair, the two ends are prone to drooping due to the weight.

When the banknotes are formed into a W shape, the two ends S2 of the short sides are inclined upward, and the top P3' is clamped by the outer convex edges, so it is not easy to sag. However, in reality, because there is a ceiling (frame 660), the two ends S2 will hit the ceiling and drop slightly, while being transported along the ceiling. However, it will not sag seriously to the extent of interfering with the accumulated banknotes.

[Banknote discharging and accumulating device: the third embodiment] Figure 16 is a front view showing the main parts of the banknote discharging and accumulating device M2 (discharging, conveying and accumulating section 800) of the third embodiment. Figures 17 to 20 are side longitudinal cross-sectional views illustrating the structure of the banknote discharging and accumulating device M2 and the discharging and sweeping actions. The same symbols are given to the parts that are the same as those of the discharging, conveying and accumulating section of the first embodiment for explanation.

The banknote discharge and accumulation device M2 of the third embodiment does not have the forming mechanism of the first embodiment. The banknotes discharged onto the payment tray in a state with rolling marks can land on the ground with good alignment through the coordinated action of the impeller 650 and the guide member (guide protrusion) 710. In this embodiment, when the banknotes with rolling marks are discharged onto the payment tray, they are discharged in a state where the rolling marks are restored, which can solve the problem of the banknotes falling off the payment tray and the accumulated banknotes being pushed out and falling by friction between the banknotes.

《Basic Structure》 The banknote discharging and accumulating device M2 has the following basic structure. That is, the discharging, conveying and accumulating section 800 constituting the banknote discharging and accumulating device M2 is a means for discharging and accumulating the banknotes discharged one by one from the circulation units 30 and 40 one by one onto the payment tray. The circulation units 30 and 40 receive and store the banknotes and discharge the stored banknotes to the outside. The discharging, conveying and accumulating section 800 has: a discharging and conveying section for discharging and conveying the discharged banknotes; The discharge conveying path 510, the discharge conveying mechanism 520 that imparts conveying force to the discharged banknotes B (hereinafter referred to as "banknotes B") on the discharge conveying path, the final discharge mechanism (hereinafter referred to as "discharge mechanism" 810) located at the downstream of the discharge conveying path and discharging the discharged banknotes onto the payment tray, and the payment tray 700 that accumulates the banknotes discharged from the discharge mechanism.

The discharge mechanism 810 has: a rotating shaft (driving shaft) 552 arranged orthogonally to the conveying direction of the discharged banknotes B and driven to rotate in the discharge direction, and a final roller pair. The final roller pair includes: a driving roller 555, 600 whose axis is fixed to the rotating shaft, and a driven roller 556, 601 that forms a clamping part n1 for conveying banknotes between each driving roller. The rear part of the banknote pressing rod 670 can be pivoted freely in the up and down directions by means of a pressing rod shaft (parallel to the rotating shaft) 672 arranged upstream of the rotating shaft 552 in the discharge direction. The banknote pressing rod is configured so that when it is in the most descended position, the front part can contact the upper surface of the payment tray (or the upper surface of the accumulated banknotes) by its own weight.

When the banknote B passes through the discharge mechanism 560, the banknote pressing rod 670 is rotated in the up-down direction by the banknotes passing through while contacting the lower surface thereof. On both outer sides of the axial direction of each driving roller 555, 600, there are respectively arranged impellers 650 whose shaft cores are fixed to the rotating shaft 552. On the upper surface of the payment tray interfering with the moving trajectory of the blade 654, a guide member (guide protrusion) 710 as a directional protrusion is provided. The guide member 710 contacts the blade and allows the blade to rotate (pass) while allowing the blade to deform elastically. Since the structure of the impeller and the guide member is the same as that of the first embodiment, the repeated description thereof will be omitted.

<Discharge conveying and accumulating section> The discharge conveying and accumulating section 800 is described in detail below. The discharge conveying and accumulating section 500 of the first embodiment has a forming mechanism 550, and the forming mechanism 550 has drive rollers 555, 600, tension rollers 556, 601, and flanges 605, 607, 609. That is, all the banknotes discharged onto the payment tray are changed into a state where the rolling marks in the long side direction are removed and reduced by the forming mechanism. In contrast, the discharge conveying and accumulating section 800 of the third embodiment only has a discharge mechanism 810 composed of each drive roller 555, 660 and each tension roller 556, 601. The discharge mechanism 810 does not have flanges 605, 607, 609 and therefore does not have the function of forming the short side of the banknote into a predetermined shape to increase the strength. The impeller 650 fixes the shaft core to the rotating shaft 552 of each drive roller and is arranged on both sides of the drive roller in the axial direction.

When the banknotes with upward rolling marks are discharged from the discharge mechanism 810, as shown in FIG18, they are released onto the payment tray in a rolled state. When the banknotes with upward rolling marks are discharged onto the payment tray by the drive rollers 555, 600 and the tension rollers 556, 601 (the final roller pair), when the banknotes with upward rolling marks are pressed by the pressure rod 670 and land on the payment tray, the downwardly bent front end may interfere with the rear end of the accumulated banknotes and push them out, or may fall from the front end of the payment tray due to its own weight. In contrast, in this embodiment, the guide member protruding from the payment tray and the coordinated action of the impeller can capture the appropriate part of the banknotes (in this case, the rear part of the banknotes) just after they are released and prevent them from moving forward too much (making them move backward), thereby preventing them from falling from the payment tray due to their own weight. Once the banknotes are accumulated, their rear parts can be pressed against the guide member by the continuously rotating blades, making them unable to move forward, thereby preventing them from being pushed out by subsequent banknotes.

According to the present embodiment, in the discharge conveying and accumulating section 800 equipped with the discharge mechanism 810, in order to solve the problem that the discharged banknotes fly out of the payment tray and fall, or the accumulated banknotes are pushed out, it is sufficient to replace the existing payment tray equipped with a guide member with one without a guide member. The discharge mechanism 810 does not shape the short side of the banknote to correct the curling mark, but only has the function of discharging to the payment tray.

<Movement of the discharge conveying and accumulation section> The following describes the movement of the banknotes of the discharge conveying and accumulation section 800 according to the third embodiment with reference to FIGS. 17 to 20. FIGS. 17(a) to (d) are movement diagrams (lateral longitudinal sections) of the discharge conveying and accumulation section 800 showing the state where the front end of the banknote has just passed through the discharge mechanism 810. After the front end of the banknote B with a directional rolling mark being discharged and conveyed in the discharge conveying path contacts the pressing rod, the banknote passes through the discharge mechanism while pushing the pressing rod upward.

Figures 18(e) and (f) are operation diagrams (lateral longitudinal section diagrams) of the discharge conveying and accumulation section 800 showing the state before the rear end of the banknote B passes through the discharge mechanism and the state just after passing through. Figures 18(g) and (h), Figures 19(i) to (l), and Figures 20(m) to (O) are operation diagrams of the process from the banknote falling on the payment tray to the blade moving the banknote backward. The processing procedures of Figures 17(a) to (d) and Figures 18(e) and (f) are not changed from the procedures of Figures 11(a) to (d) and Figures 12(e) and (f), so their description is simplified. The processing procedures of Figures 18(g), (h), 19(i) to (l), and 20(m) to (o) are the same as those of Figures 12(g), (h), 13(i) to (l), and 14(m) to (o) in the first embodiment, except that the front and rear parts are bent downward due to the upward curling of the discharged banknotes. Therefore, the repeated descriptions will be reduced and the description will be centered on the differences. Therefore, the repeated parts of the descriptions can be understood by referring to the corresponding descriptions in the first embodiment.

In FIG. 17(a), the banknote B conveyed along the discharge conveying path 510 contacts the lower surface of the pressure rod 670 at a position just in front of the clamping portion n1 of the final roller pair and starts to be pushed. Since the pressure rod shaft 672 is located behind the rotation axis 552, the front end of the banknote contacts the pressure rod at a position further upstream than the rotation axis and starts to be pushed upward. Moreover, since a sufficiently long distance L3 is ensured between the pressure rod shaft and the contact point C, and the initial angle θ of the pressure rod is large to a degree close to 180 degrees, the pressure rod can be pushed upward with a small force (FIG. 19(b), (c)). The front end of the banknote with a downward bending mark is given a strong force in the discharge conveying path 510 as in the first embodiment, so that the curling mark is temporarily corrected, thereby pushing the pressure rod upward. When the banknote passes through the discharge mechanism 810, it passes through the clamping portion n1 of each drive roller 555, 600 and each tension roller 556, 601.

In FIG. 17(d), the front end of the banknote begins to protrude from the clamping portion n1, and the pressure rod is pushed by the banknote and further pushed upward. Although the front end of the banknote just discharged from the clamping portion n1 recovers the downward bending mark, the pressure rod can be pushed upward with a small force based on the above reasons, so the pressure rod can be pushed upward with a small force that is not inferior to the pressure rod. In FIG. 18(e), the front part of the banknote other than the rear part clamped by the clamping portion n1 of each driving roller and each driven roller is curled downward, but the pressure rod 670 is configured to be pushed upward with a small force. Therefore, the banknote can continue to push the pressure rod upward as shown in the figure. The height position of the pressure rod at this time is not the maximum height of the movable area of the pressure rod, but it is pushed up to the maximum limit as much as possible. That is, the banknote is discharged along the lower surface of the pressure rod that is pushed up to the height position shown in the figure, and the front end of the banknote contacts the upper surface of the payment tray (the upper surface 705a of the entry and exit member). Figure 18 (f) shows the state where the rear end of the banknote B is completely separated from the discharge mechanism 810. The banknote that becomes free is not formed into a straight shape like the first embodiment. As shown in the figure, at this stage, the contact portion with the front end of the pressure rod 670 is pushed downward and deformed into a concave shape. Since the banknotes have a force to be released in the discharge direction, when the impeller and the guide member 710 do not exist, they will be discharged along the lower surface of the pressure rod. Therefore, it becomes easy to contact with the accumulated banknotes and push them out to make them fall, or it is easy for them to fall from the front end of the payment tray.

Next, at the stage of Figure 18 (g) and (h), the rear part of the banknote that has been separated from the clamping part n1 of the final roller pair returns to its original shape of curling downward. The front end of the banknote is bent downward and is likely to fall off the front end of the payment tray if this state is left unchecked. In particular, when the length of the payment tray in the front-to-back direction is continuously shortened, when the released banknote lands on the payment tray while being pressed by the pressure rod, its front end will protrude significantly from the shortened front edge of the payment tray and become easy to fall. In order to solve this problem, the present invention is configured such that, as shown in FIG. 18(g) and (h), after the rear end of the banknote leaves the clamping portion n1, the banknote is stopped from moving forward and swept backward by the coordinated action of the impeller blades 654 and the guide member 710. That is, on the upper surface of the payment tray corresponding to the retreat space 702 provided at the rear of the payment tray 700, the guide member 710 as a protrusion is fixedly arranged at a position corresponding to the moving track of the impeller blades 654. Through the coordinated operation of the guide member and the impeller, the banknote B once discharged onto the payment tray moves back toward the space 702, thereby eliminating the state where the front end protrudes from the front edge of the payment tray.

The configuration and height of the guide member 710 are configured such that, as shown in FIG. 18(g) and (h), the sweeping by the blades is started at the stage where the rear part of the banknote dropped onto the payment tray is in the air before it drops to the upper surface 716 or the rear edge 716a of the guide member. That is, the first contact between the falling banknote and the blade is made when the banknote is in the air (at the time of FIG. 18(f) or (g)). Because the behavior of banknotes is not consistent, the front end of the blade may also contact the rear part of the banknote after the rear part of the banknote drops to the upper surface of the guide member or while it is dropping. It has been confirmed that the banknote can be swept backward without any problem even in this case. The length and position of each blade 654 are set so that it will slide against the outer surface of the guide member 710 during the rotational movement.

The rotation speed of the impeller, the rotation timing of the blade for discharging the banknotes, and the length of the blade (the rotation path of the front end of the blade) are selected so that the blade 654c rotating from above can capture the curved rear part of the banknote discharged onto the payment tray and pull it down toward the guide member 710, as shown in Figures 18(g), (h), and 19(i), (j). By adopting such a structure, even if the discharged banknotes want to fly forward too much, the rear end of the banknotes can be captured by the blade 654c in the air at an early stage of the rear end of the banknotes being discharged and start to sweep downward and backward. Furthermore, when the blade 654c reaches the rear edge 716a of the guide member, the rear portion of the banknote can be clamped between the blade and the rear edge, and the entire banknote can be moved backward while being clamped between the front end of the blade and the curved guide surface 720 (Figure 19 (k) (l), Figure 20 (m) to (O)). As in the case of the first embodiment, by appropriately selecting and setting the contact timing of each blade and each banknote, in other words, the rotation speed of each blade and the release speed of each banknote, the action of forcibly pulling the banknote in the downward direction and backward can be started when the rear portion of the banknote in the air contacts the blade. Then, when the blade descends to the point where it contacts the upper surface and rear edge of the guide member, the rear of the banknote is sandwiched between the blade and the guide member, and the subsequent rotation of the blade allows the banknote to move reliably backward along the curved guide surface 720. Therefore, all banknotes, regardless of the difference in the length direction, can be accumulated on the payment tray with the rear ends aligned, without falling from the front edge of the payment tray.

In this embodiment, as shown in Figures 18(g) to 20(O), the banknotes discharged onto the payment tray are pulled backwards once the front end lands on the payment tray (on the entry and exit member 705). If this phenomenon is observed from the return port side, the banknotes are discharged in a state where the front end protrudes from the payment tray, and then are pulled backwards and stop. The banknotes discharged from the discharge mechanism 810 may have different falling paths and timings because the rolling marks are restored. Therefore, the blades may not always be able to capture the rear of the banknote at the same time in the air. It is also possible that the rear of the banknote falls onto the guide member before contacting the blades. However, according to this embodiment, even in such a case, the blade can still clamp the rear of the banknote between it and the guide member and sweep it backward.

To explain in more detail, the banknote discharged from the dispensing mechanism 810 has a rolling mark, and the rolling mark may be restored at the moment when the banknote leaves the dispensing mechanism, so that the rear end of the banknote is rolled into a shape that avoids the blade, and the rear part of the banknote falls on the guide member 710 before contacting the blade. However, according to the structure of this embodiment, even in this case, the rear part of the banknote is hooked by the guide member to prevent it from moving forward, and is captured by the front end of the blade that descends later and swept backward. As a result, the banknote can be prevented from falling off the payment tray.

Next, the following further describes the structure and function of the impeller 650, the pressure rod 670, and the guide member 710, etc., in the process of pressing the banknote discharged from the discharge mechanism 810 downward by the pressure rod, and the action of moving the banknote backward by the impeller. As shown in FIG. 18 (g) and (h), when the rear of the banknote B discharged from the discharge mechanism 810 to the payment tray is still in the air, if the blade 654c rotating downward contacts the rear of the banknote, the blade can reliably capture the banknote, and cooperate with the downward pressing action of the pressure rod to start the action of forcibly sweeping downward and backward. That is, the banknote discharged from the dispensing mechanism 810 is forced forward and tends to move toward the front edge of the payment tray 700 in the air. In contrast, the blade 654c moving downward contacts the rear of the banknote in the air, thereby weakening the force of the banknote to move forward and stopping it from moving forward, thereby guiding it in the direction of the rotation movement of the blade 654c (downward and backward). In FIG. 18 (g) (h), if the blade 654c captures the rear of the banknote B in the air and continues to rotate downward, as shown in FIG. 19 (i) (j), the blade 654c will press the rear of the banknote downward until it contacts the upper surface 716 and the rear edge 716a of the guide member 710. At this point, the rear of the banknote is clamped and held between the lower surface (high friction area 656) of the blade 654c and the rear edge 716a. Therefore, by further rotating the blade, the banknote moves backward along the curved guide surface 720 and the rear guide surface 722.

At the time point of Fig. 20 (O), the blade 654c is roughly separated from the rear end of the banknote, and the banknote stops moving backward. If necessary, a stopper for aligning the rear ends of each banknote swept backward can also be provided at the end of the space 702 for retreat.

As described above, at a time earlier than the rear of the banknote discharged from the discharge mechanism 810 descends to (contacts) the rear edge 716a, the blade 654c contacts the rear of the banknote at a position further forward and above the rear edge 716a and begins to sweep it downward and backward (in the direction opposite to the discharge direction of the banknote). In other words, the contact position (first contact position) C1 between the front end of the blade and the banknote can be set at a farther position on the rotation track of the front end of the blade. Therefore, the banknote can be pulled backward at an early stage before the banknote lands on the payment tray, and the banknote accumulation processing speed can be accelerated. Furthermore, by providing the guide member 710, when the rear end of the banknote on the way down is located at a position higher than the upper surface 701 of the payment tray, it can contact the rear edge 716a of the guide member. That is, the rear end of the banknote can be hooked by the rear edge 716a before the rear end of the banknote lands on the payment tray. Therefore, the banknote that once lands on the payment tray in a state of flying out from the front edge of the payment tray can be quickly pulled backwards and stopped at the most appropriate position. In particular, in the case of a wrinkled banknote, when it is discharged onto the payment tray, it may not be possible to fully pull it backwards by only pressing with the blade. Therefore, the point where the blades touch the banknotes is set in the air, and the blades and guide components are pulled together to ensure the movement of the wrinkled banknotes.

According to the above structure, regardless of the size of the long side of the banknotes, the rear ends of all banknotes discharged onto the payment tray can be aligned in order, thereby preventing the banknotes from excessively protruding or falling from the front edge of the payment tray, and making the multiple banknotes accumulated on the payment tray the most suitable state for users to take out in batches. There is also a strong demand for miniaturizing and shortening the payment tray as much as possible, because the discharged banknotes can be aligned with the rear ends based on the inside of the payment tray, and such a demand can be met.

As described above, according to this embodiment, the following problems can be solved: the front end of the banknotes easily passes over the front edge of the payment tray due to the force of the banknotes when being discharged from the discharging mechanism 550 and slides down due to their own weight. In addition, the rear of the accumulated banknotes is pressed between the blades of the impeller that rotates continuously and the guide member, so the problem of subsequent banknotes pushing out the accumulated banknotes can also be solved.

[Summary of the structure, function and effect of the present invention] 《First invention (first and second embodiments)》 The paper discharge accumulation device M2 of the first embodiment of the first invention is a means for continuously discharging and accumulating the paper discharged from the circulation units 30, 40 one by one with the short side leading to the discharge tray 700. The circulation units 30, 40 store the transported paper and discharge the stored paper to the outside. The paper discharge accumulation device M2 has: a discharge conveying path 510 for conveying the paper to the discharge tray, and a forming mechanism 550 for forming the short side shape (the shape of the side extending in the direction intersecting the conveying direction) of the paper conveyed along the discharge conveying path into a predetermined shape (a shape for strengthening strength) over the entire length of the long side direction and then discharging it onto the discharge tray. In the forming operation based on the forming mechanism 550, an upward protrusion (a bent portion protruding upward) and a downward protrusion (a bent portion protruding downward) are alternately formed along the short side direction of the paper, and the two end portions S2 of the short side of the paper are tilted upward (protruding obliquely upward). In paper processing devices such as banknotes, the demand for recycling machines is increasing. When multiple banknotes are ejected, in order to increase the processing speed, it is preferable to configure them to be ejected one by one continuously onto the discharge tray, and after all the banknotes are accumulated, the user takes out the banknote bundle. For learning machines that perform one-by-one withdrawal, the next banknote will not be withdrawn until the user takes out the withdrawn banknote. Therefore, it takes time to withdraw all the banknotes. However, even if the withdrawn banknote is curled, it will not cause the problem of collision with the accumulated banknotes. In the learning machine, the time required to withdraw each of the 10 banknotes depends on the operation time required by the user to withdraw the banknotes, which is usually 2 seconds.

On the other hand, by continuously discharging and accumulating banknotes one by one on the discharge tray for batch removal, the time required to withdraw each of 10 banknotes can be shortened to 1.5 seconds, even though the discharge speed of banknotes is the same as that of the learning machine. However, in the case of continuous accumulation, a new problem of collision with existing banknotes will occur, and the problem of collision with existing banknotes is solved by using simple specifications. That is, in the present invention, it is possible to prevent poor discharge and poor accumulation on the discharge tray (pushing out of the preceding banknote, uneven accumulation state, inconsistent stop position of the banknote itself, falling, etc.) caused by the curling marks formed on the banknotes. It can also solve the problem of poor discharge and poor accumulation caused by deformation and reduced strength of folds and wrinkles formed on the banknotes in addition to rolling marks. The two ends S2 and P3 of the short side of the banknote are located above the downward protrusion P2 to avoid collision with the accumulated banknotes. By maintaining the height of the upward protrusion P3 at the two ends to be equal to or higher than the upward protrusion P1 in the center, the possibility of the above-mentioned collision is further reduced.

The second embodiment of the paper discharge and accumulation device M2 is characterized in that the short side shape of the paper after being formed by the forming mechanism 550 is roughly symmetrical. Based on the short side shape of the paper after being formed by the forming mechanism, it is sufficient to make the two ends retreat upward, but considering the process of discharging onto the discharge tray, the stability of seating after discharging, the operability of the user, etc., a symmetrical shape is preferred.

The paper discharge and accumulation device M2 of the third embodiment is characterized in that the short side of the paper after being formed by the forming mechanism 550 is roughly W-shaped. Based on the short side of the paper after being formed by the forming mechanism, it is sufficient to make both ends retreat upward, and the roughly W-shaped having an upward protrusion P1 in the center and downward protrusions P2 on the left and right sides, respectively, can be compacted by reducing the number of parts of the forming mechanism, and has high practicality.

The fourth embodiment of the paper discharge and accumulation device M2 is characterized in that the forming mechanism 550 has at least a rotating shaft 552, a central flange 605, two roller pairs, and outer flanges 607, 609; the rotating shaft 552 is arranged orthogonally to the conveying direction of the paper and is driven to rotate in the discharge direction; the central flange 605 has a shaft core fixed to the rotating shaft; the two roller pairs are composed of two driving rollers 555, 600 and a driven roller. The paper sheet discharging mechanism is composed of two drive rollers 555, 600, which are arranged at predetermined intervals on both sides of the central flange in the axial direction, and the shaft core is fixed to the rotating shaft. The driven rollers 556, 601 respectively form a clamping portion n1 for paper conveying between the driven rollers and the drive rollers; the outer flanges 607, 609 are respectively arranged on the outer sides of the two drive rollers in the axial direction, and the shaft core is fixed to the rotating shaft. The previous discharge mechanism for discharging paper onto the payment tray is composed of a roller pair including a drive roller and a driven roller. In the present invention, only three flanges are added to the previous discharge mechanism. By reducing the number of parts to the minimum necessary, the structure can be simplified and miniaturized. Although the space E used for storage is limited, this structure allows for a slender design.

The fifth embodiment of the paper discharge accumulation device M2 is characterized in that it is provided with a paper pressing rod 670, the rear portion of which is rotatably supported in the up and down directions by a pressing rod shaft 672, so that the front portion of the paper pressing rod 670 (the portion further forward than the pressing rod shaft) passes over the rotating shaft and protrudes on the discharge tray, and the pressing rod shaft 672 is arranged closer to the paper conveying direction than the rotating shaft 552. The paper pressing rod is located upstream of the rotating shaft 552 and is arranged above the discharge conveying path 510; in the process of the paper passing through the forming mechanism, the paper pressing rod is affected by the paper passing below it and rotates in the up-down direction. The paper pressing rod is arranged in an axial position interfering with the central flange 605, and the part of the paper pressing rod interfering with the central flange has an opening 673 that avoids the central flange and allows rotation in the up-down direction. The pressing rod shaft is located upstream of the rotating shaft 552, and the front part of the pressing rod protrudes forward over the rotating shaft. Therefore, the pressing rod becomes elongated and the initial angle θ when descending becomes larger, and it is easy to push the pressing rod upward when the paper rushes in.

The paper discharge accumulation device M2 of the sixth embodiment is characterized in that when the paper pressing rod 670 is descending, a part of the paper pressing rod interferes with the discharge conveying path. The paper contacts the pressing rod and begins to push it upward, and becomes in the discharge conveying path 510 upstream of the forming mechanism 550. Because the distance between the pressing rod shaft and the contact portion C between the pressing rod and the front end of the paper can be shortened, it becomes easier to push the pressing rod upward based on the paper.

The paper discharge accumulation device M2 of the seventh embodiment is characterized in that it is configured to prevent a part of the paper from being inserted between the two inner edges of the opening portion 673 of the paper pressing rod 670 and the two outer sides of the central flange 605. In other words, the width of the central flange is configured to prevent a part of the paper from being inserted into the gap G2 formed between the two inner edges of the opening portion and the two outer sides of the central flange. The paper with extremely reduced strength (wrinkled paper) may not be able to fully push up the paper pressing rod after being discharged from the forming mechanism, causing buckling, etc. The reason is that if the gap between the central ridge and the open part of the paper pressing rod is too large, part of the paper may fall into the gap, which reduces the strength and reduces the force of pushing the paper pressing rod upward. In the present invention, by fully expanding the width of the central ridge to eliminate or reduce the gap, a part of the wrinkled paper can be prevented from falling into the gap, and the outer peripheral surface of the central ridge supports the paper to maintain an upward posture, so that it does not push the paper pressing rod.

The paper discharge accumulation device M2 of the eighth embodiment is characterized in that the discharge tray 700 has a base surface 701, a protrusion 703, a recessed member (inclined surface forming member) 705 and an elastic member. The protrusion 703 is respectively protruded forward from both ends of the base surface in the width direction and has an upwardly inclined surface 703a on the upper surface; the recessed member 705 is configured to rotate the front portion in the up-down direction by supporting the rear portion in the groove or hole 704 provided on the inner edge of each protrusion; the elastic member applies force to the recessed member to the upward protruding position. Because the ejection member is always in a protruding state, it has the function of braking the ejected paper. On the other hand, when the user removes the paper accumulated on the ejection tray, the protruding ejection member will cause some obstruction. Therefore, the ejection member is configured so that the user can push it down to retreat.

The circulating paper processing device 1 of the ninth embodiment comprises: a paper input port (payment port) 5, an introduction portion 11 for receiving and conveying (carrying in) the paper input from the input port along the long side direction of the paper, a circulating unit 30, 40 for receiving and storing the paper and ejecting the stored paper to the outside, and any of the above-mentioned paper discharge and accumulation devices M2, wherein the circulating unit comprises a circulating roller, which accumulates and stores the paper one by one on the outer peripheral surface by forward rotation, and ejects the paper on the outer peripheral surface one by one by reverse rotation. The circulating paper processing device has the functions and advantages of the above-mentioned paper discharge and accumulation devices M2.

《The Second Invention (Third Implementation Form)》 The first implementation form of the second invention is a paper discharge accumulation device M2, which is a means for discharging and accumulating the paper sheets discharged from the circulation units 30, 40 one by one with their short edges leading to the discharge tray 700. The circulation units 30, 40 store the transported paper sheets and discharge the stored paper sheets to the outside. The paper discharge accumulation device M2 has: a means for transporting the paper sheets to the discharge tray; The paper discharge conveying path 510 is provided, the final discharge mechanism 810 is located downstream of the discharge conveying path, the discharge tray 700 accumulates the paper discharged from the final discharge mechanism, and the paper pressing rod 670 is used to press the paper discharged from the final discharge mechanism. The rear part of the paper pressing rod 670 is pivotally supported so as to be freely rotatable in the vertical direction, and the front part protrudes from the discharge tray. The final discharge mechanism 810 includes: a rotating shaft 552 and a final roller pair. The rotating shaft 552 is arranged orthogonally to the conveying direction of the paper and is driven to rotate in the discharge direction. The final roller pair includes: at least two drive rollers 555, 600 whose cores are fixed to the rotating shaft, and driven rollers 601, 605 that form a clamping portion n1 for paper conveying between the driven rollers and the drive rollers.

Each driving roller is provided with an impeller 650 with a core fixed to a rotating shaft on the axial outer side. The blades constituting each impeller have a moving track that contacts the banknotes discharged from the final discharge mechanism and pushes them downwards during the process of rotating downwards toward the upper surface of the discharge tray. A guide protrusion (guide member) 710 is provided on the upper surface of the discharge tray that interferes with the moving track of the blade. The guide protrusion 710 interferes with the blade, allowing the blade to rotate and move (pass) while allowing the blade to deform elastically. The guide protrusion has: a first contact portion 716, 716a that contacts the rear of the paper discharged onto the discharge tray by the final discharge mechanism (final roller pair) at a position higher than the upper surface of the discharge tray (in advance of the upper surface of the discharge tray), and a (curved) guide surface 720 that extends (curved) downward from the first contact portion to the rear (upstream side) in the discharge direction. Because the first contact portion is at a position where the front end of the rotationally moving blade contacts, the front end of the blade can pass through while being elastically deformed and in contact. In order to enable the paper to be swept backwards by the coordinated action of the blade, the curved guide surface 720 and the rear guide surface 722 are also selected in such a way that the front end of the blade is elastically deformed while in contact and moves.

The second embodiment of the paper discharge accumulation device M2 is characterized in that the moving trajectory of the blade is set so that the first contact between the blade and the paper occurs when the rear end of the paper is in the air, and the blade is ensured to be integrated with the timing of paper discharge. In the early stage after the rear end of the paper leaves the final discharge mechanism, that is, when the rear end of the paper is in the air, the blade captures the paper and starts to sweep backward, thereby reliably preventing the paper from flying out from the front end of the discharge tray and falling.

The paper discharge accumulation device M2 of the third embodiment is characterized in that after the blade 654 contacts the rear part of the paper at a position higher than the first contact part, the paper part in contact with the blade and the blade pass through the first contact part and move toward the curved guide surface 720 in sequence during the process of rotating downward and backward. By making the blade contact with the rear part of the paper at a position higher than the first contact part, that is, in the air, the timing of paper discharge and the timing of blade movement are integrated, thereby starting the sweeping action from the rear earlier. As a result, the rear part of the paper can be contacted with the first contact part of the guide member earlier, and the sweeping to the rear can be continued quickly.

The paper discharge accumulation device M2 of the fourth embodiment is characterized in that the rear portion of the paper pressing rod 670 is supported by a pressing rod shaft 672 so as to be freely rotatable in the up-and-down direction, and the front portion thereof is allowed to protrude on the discharge tray beyond the rotating shaft, and the pressing rod shaft 672 is arranged upstream of the rotating shaft 552 in the paper conveying direction, and arranged above the discharge conveying path 510. The paper pressing rod, because the pressing rod shaft provided at the base end is arranged upstream of the final discharge mechanism, the strength of the paper with curling marks etc. conveyed in the discharge conveying path is temporarily strengthened, and the paper pressing rod can be pushed upward even with a small force. The impeller and guide protrusions, through coordinated action with the paper pressing rod, can control the falling path of the banknotes and sweep them backwards.

The paper discharge accumulation device M2 of the fifth embodiment is characterized in that the discharge tray 700 has a base surface 701, a protrusion 703, a recessed member (inclined surface forming member) 705 and an elastic member. The protrusion 703 is respectively protruded forward from both ends of the base surface in the width direction and has an upwardly inclined surface 703a on the upper surface; the recessed member 705 is configured to rotate the front portion in the up-down direction by supporting the rear portion in the groove or hole 704 provided on the inner edge of each protrusion; the elastic member applies force to the recessed member to the upward protruding position. Because the ejection member is always in a protruding state, it has the function of braking the ejected paper. On the other hand, when the user removes the paper accumulated on the ejection tray, the protruding ejection member will cause some obstruction. Therefore, the ejection member is configured so that the user can push it down to retreat.

The circulating paper processing device of the sixth embodiment comprises: a paper input port (payment port) 5, an introduction portion 11 for receiving and conveying (carrying in) the paper input from the input port along the long side direction of the paper, a circulating unit 30, 40 for receiving and storing the paper and ejecting the stored paper to the outside, and any of the above-mentioned paper discharge and accumulation devices M2, wherein the circulating unit comprises a circulating roller, which accumulates and stores the paper one by one on the outer peripheral surface by forward rotation, and ejects the paper on the outer peripheral surface one by one by reverse rotation. The circulating paper processing device has the functions and advantages of the above-mentioned paper discharge and accumulation devices M2.
