Description

Technical Field

[0001] This invention relates to the field of banknote counting and identification technology, and more specifically to a banknote counting machine. Background Technology

[0002] A banknote counter is an electromechanical device that integrates the counting and counterfeit detection of banknotes. It is an indispensable tool in places with large-scale cash circulation.

[0003] Existing banknote counting machines, such as the horizontal two-port banknote counting machine disclosed in publication number CN203659051U, when the banknote counting machine detects counterfeit banknotes, the counterfeit detection mechanism sends a signal to the control unit of the banknote counting machine, causing the control unit to control the banknote separating motor to drive the banknote separating plate to swing downward through the rotating shaft and make one end contact with the banknote passing track. At this time, the banknotes being transported will enter the banknote separating track, which is composed of the banknote separating plate and the banknote receiving plate, and fall onto the banknote receiving plate, separating them from genuine banknotes, thereby realizing the automatic separation of counterfeit banknotes.

[0004] However, the aforementioned existing technologies still have some shortcomings for users. Because normal banknote counting machines feed banknotes at a very high speed, when the banknote sorting plate is oscillating, it is easy for it to interfere with the banknotes being fed, resulting in banknote jamming. Especially when counterfeit and genuine banknotes are mixed together, the banknote sorting plate needs to oscillate frequently, which exacerbates the problem of banknote jamming. Therefore, existing banknote counting machines cannot effectively solve the problem of automatic identification when multiple genuine and counterfeit banknotes are mixed together. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a banknote counter that can be used in complex scenarios where there are large quantities of counterfeit banknotes and genuine banknotes are mixed together, and has good reliability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a banknote counter, comprising a body, and a banknote feeding mechanism, an identification mechanism, a sorting mechanism, a genuine banknote dispensing mechanism, and a counterfeit banknote dispensing mechanism disposed on the body. The body has banknote feeding channels, identification channels, sorting channels, genuine banknote dispensing channels, and counterfeit banknote dispensing channels corresponding to and connected to each of the mechanisms. The sorting mechanism includes a detection component, a pressure feeding wheel, and a sorting guide plate. The pressure feeding wheel includes a first pressure feeding wheel located in front of the detection component and a second pressure feeding wheel located behind the detection component. The sorting guide plate is disposed at the entrance of the genuine banknote dispensing channel and the counterfeit banknote dispensing channel and has two position states: guiding banknotes into the genuine banknote dispensing channel or the counterfeit banknote dispensing channel. When the detection component detects a banknote, the sorting guide plate performs an action to switch between the two position states according to the identification result of the identification mechanism.

[0007] With the above structure, the sorting guide plate is activated only after the detection component determines that the banknote has entered the sorting channel, rather than simply using a delay. This allows for precise control of the banknote counter and prevents situations where the sorting guide plate activates prematurely before the banknote has reached it, thus affecting the dispensing of the previous banknote, or where the banknote has already been delivered to the sorting guide plate but the plate has not yet activated. These situations are prone to causing banknote jams. Therefore, this invention, in conjunction with the detection component, can effectively avoid these banknote jamming situations.

[0008] The present invention is further configured such that the linear velocity of the second pressure feeding wheel is greater than the linear velocity of the first pressure feeding wheel.

[0009] The above structure enables the sorting channel to have slow entry and fast exit. Slow entry ensures that banknotes enter and are detected accurately, while fast exit ensures that banknotes leave the sorting guide plate at the end of the sorting channel quickly, thus ensuring that the sorting guide plate, which needs to swing and change its position, does not retain banknotes for as long as possible.

[0010] The present invention is further configured such that: the sorting guide plate is provided with a notch adapted to the width of the second pressure feeding wheel, and a protruding retaining edge is provided in the notch, the retaining edge abutting against the side of the second pressure feeding wheel.

[0011] With the above structure, the notch can avoid the pressure roller, while allowing the front end of the sorting guide plate to extend into the conveying path of the pressure roller, so that the banknotes can accurately enter the sorting guide plate when they are pressed and conveyed by the pressure roller; at the same time, the structure of the baffle can block the small gap and prevent the rapid airflow from causing noise when passing through the small gap.

[0012] The present invention is further configured such that: the upper and lower sides of the outlet end of the sorting channel are provided with grooves, and the sorting guide plate can be extended into the grooves. When the sorting guide plate is extended into the groove, a clearance is left on the side of the sorting guide plate located in the groove, and the part of the sorting guide plate located outside the groove is lower than the plane of the sorting channel.

[0013] With the above structure, the plane below the sorting channel allows banknotes to smoothly enter the sorting guide plate along the plane of the sorting channel without getting stuck; the clearance gap ensures that when the sorting guide plate swings to switch positions, if the banknote on that side has not completely left the sorting guide plate, the banknote will not get stuck between the sorting guide plate and the groove due to the switching of the sorting guide plate, but will smoothly leave along the clearance gap, thus better avoiding the problem of banknote jamming.

[0014] The present invention is further configured such that: measuring elements are provided on both sides of the groove portion, the measuring elements including a telescopic measuring rod that abuts against the sorting guide plate, an elastic device for supporting the measuring rod, and a distance sensor for detecting the telescopic distance of the measuring rod; the sorting guide plate abuts against the measuring rod and drives its telescopic movement, and the size of the clearance gap is controlled by feedback from the distance sensor.

[0015] With the above structure, the size of the clearance gap can be preset using a measuring component, which can be limited according to banknotes of different thicknesses. Thus, when the sorting guide plate switches positions, the measuring component provides feedback to ensure that the clearance gap is formed and its size is appropriate. This avoids the clearance gap being too large or too small due to mechanical errors caused by swinging during long-term operation, which could affect the normal sorting of banknotes or cause them to get stuck.

[0016] The invention is further configured such that: the sorting guide plate is hinged to the machine body, and a driving component is provided at its hinged end; the driving component is used to drive the sorting guide plate to swing to switch between two position states. The identification mechanism includes a flip-up component that can be opened relative to the identification channel; one end of the flip-up component is hinged to the machine body, and the other end is provided with a latching component that engages with the machine body.

[0017] With the above structure, the identification channel is fully exposed after the flip-top is opened, making it convenient for users to perform maintenance or clean dust.

[0018] The present invention is further configured such that: the sorting mechanism includes a channel plate that is separable from the sorting channel, the channel plate has grooves on both sides, and the machine body has a slide rail that slides in cooperation with the grooves.

[0019] The separation of the channel plate through the above structure exposes the entire sorting channel, making it convenient for users to inspect or clean the sorting channel.

[0020] The present invention is further configured such that the sorting channels have different length specifications, and the length of the sorting channels is at least able to accommodate one banknote.

[0021] With the above structure, the sorting channel can accommodate one banknote, allowing the previous banknote to fully enter the sorting guide plate before the next banknote enters. This provides the sorting guide plate with sufficient time and space to switch positions in terms of control.

[0022] The present invention is further configured to include a sensor assembly and a control system. The sensor assembly includes a first sensor for detecting the position status of the sorting guide plate, a second sensor for detecting whether banknotes at the exit of the sorting channel have entered the sorting guide plate, and a third sensor located in the genuine banknote dispensing channel and the counterfeit banknote dispensing channel for detecting whether banknotes have been dispensed. The control system is electrically connected to the drive motor inside the machine body, the control system is electrically connected to the identification module inside the identification mechanism, the control system is electrically connected to the detection component, and the control system is electrically connected to the sensor assembly.

[0023] The present invention is further configured such that: the control system is equipped with a control strategy, the control strategy including: Step S1: Obtain the authentication result of the banknote from the authentication module within the authentication institution. If it is a genuine banknote, continue executing the preset program of the banknote counter; if it is a counterfeit banknote, proceed to step S2. Step S2: Control the drive motor to reduce its speed, thereby reducing the banknote conveying speed; Step S3: Obtain the signal from the detection component. When the detection component detects counterfeit banknotes entering, determine whether there are banknotes at the exit of the sorting channel that have not yet fully entered the sorting guide plate. If there are, wait for the banknotes to fully enter the sorting guide plate before proceeding to step S4. If not, proceed directly to step S4. Step S4: Determine whether the current position of the sorting guide plate needs to be switched. If so, control the sorting guide plate to switch to the position state that guides the banknotes into the counterfeit banknote dispensing channel. Step S5: The counterfeit banknote dispensing sensor in the counterfeit banknote dispensing channel detects the dispensing of counterfeit banknotes and returns to step S1.

[0024] The aforementioned structure, sensor components, and control system can better meet the stringent usage scenarios where genuine and counterfeit banknotes are mixed, the quantity of counterfeit banknotes is large, and the sorting guide plate needs to frequently switch position states.

[0025] In summary, the present invention has the following beneficial effects: The present invention incorporates a detection component at the sorting mechanism, located between the first and second pressure rollers. This detection component can detect the banknote's position in advance when it enters the first pressure roller but has not yet reached the second pressure roller, and prepare the sorting guide plate accordingly. This ensures that the swinging of the sorting guide plate does not interfere with the banknotes being transported, thereby greatly solving the problem of interference between the sorting guide plate and the banknotes during transport when the plate is switching positions, and preventing banknote jamming.

[0026] The present invention also includes a first and a second pressure roller with a linear velocity difference, which enables the banknotes to enter slowly and exit quickly at the sorting mechanism, ensuring that the banknotes stay on the sorting guide plate for a very short time. When switching positions, the banknotes will not interfere with the banknotes in the sorting channel, thus avoiding banknote jamming.

[0027] The present invention also includes a sensor assembly and a corresponding control strategy. By using multiple sensors to detect the position of banknotes, and in conjunction with the control strategy, the sorting guide plate operates when it does not interfere with the banknotes. This greatly solves the problem of banknote jamming that may occur when the sorting guide plate operates continuously in the case of multiple counterfeit and genuine banknotes mixed together.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings.

[0041] This embodiment discloses a banknote counting machine, such as Figures 1-9 As shown, the device includes a main body 1. The main body 1 first feeds banknotes into the banknote feeding channel 12 through the banknote feeding mechanism 2's banknote feeding wheel. The banknote feeding wheel feeds banknotes one by one. Then, the banknotes enter the identification channel 13 along the banknote feeding channel 12. The identification mechanism 3 in the identification channel 13 identifies the authenticity of the banknotes. After identification, the banknotes continue to be conveyed downwards and enter the sorting channel 14. The sorting mechanism 4 in the sorting channel 14 can send genuine banknotes and counterfeit banknotes to the lower genuine banknote dispensing channel 15 and the upper counterfeit banknote dispensing channel 16, respectively. The genuine banknote dispensing mechanism 5 and the counterfeit banknote dispensing mechanism 6 at the genuine banknote dispensing channel 15 and the counterfeit banknote dispensing channel 16 guide the banknotes outwards to prevent the banknotes from blocking the channel openings. The specific genuine banknote dispensing mechanism 5 and the counterfeit banknote dispensing mechanism 6 can be mature banknote dispensing impellers or banknote dispensing deflectors in this field. Generally speaking, genuine banknotes need to be stacked before dispensing, so impellers are preferred. Counterfeit banknotes only need to be placed on the banknote return table, so deflectors can be selected.

[0042] The sorting mechanism 4 in this embodiment includes a detection component 401, a pressure feeding roller 402, and a sorting guide plate 403. The pressure feeding roller 402 includes a slow-speed first pressure feeding roller 4021 and a fast-speed second pressure feeding roller 4022. That is, the linear velocity of the second pressure feeding roller 4022 is greater than that of the first pressure feeding roller 4021, thereby enabling banknotes to enter slowly and exit quickly in the sorting channel 14. The first pressure feeding roller 4021 feeds banknotes relatively slowly, allowing the detection component 401 behind it to accurately detect the entry of banknotes. When the detection component 401 detects a banknote, the sorting guide plate 403 operates according to the identification result of the identification mechanism 3; if it is a genuine banknote, the sorting guide plate 403 switches to the upper position, such as... Figure 4After the top is blocked, the banknotes in the sorting channel 14 can only be conveyed to the genuine banknote dispensing channel 15 below by the second pressure feeder 4022 and the sorting guide plate 403; if it is a counterfeit banknote, the sorting guide plate 403 switches to the lower side, such as... Figure 5 The lower part is blocked, so the banknotes are conveyed to the upper counterfeit banknote dispensing channel 16, thereby achieving the separation of genuine and counterfeit banknotes. The specific detection component 401 can be an infrared sensor, which includes a transmitter and a receiver. When the infrared signal between the two is blocked, it means that the banknote has been conveyed. When the signal is reconnected, it means that the banknote has left.

[0043] As a supplement to another embodiment, further reference is made to Figures 6-7 A notch 7 is provided on the sorting guide plate 403. This notch 7 is adapted to the second pressure conveying roller 4022. (Refer to...) Figures 2-5 The channel plate 41 has a pressure roller with the same width that abuts against and cooperates with the second pressure roller 4022. Therefore, when the sorting guide plate 403 swings, the notch 7 can adapt to the upper and lower rollers without causing interference. At the same time, a protruding baffle 71 is provided in the notch 7. The baffle 71 just abuts against the side of the second pressure roller 4022 and the lower pressure roller. This can block the air flow between the upper and lower layers at the notch 7. If the baffle 71 is not provided, there will be a small gap between the notch 7 and the roller. When banknotes pass through one side of the sorting guide plate 403, the air flow speed driven by the banknotes will increase, causing the air on the other side to flow through the small gap, producing a relatively sharp "hissing" noise. The baffle 71 can effectively solve the noise problem, leaving only the normal sound of banknote conveying. The baffle 71 is preferably a rubber baffle or has a surface covered with rubber material, so that it flexibly abuts against the side of the roller.

[0044] As a supplement to another embodiment, further reference is made to Figures 4-5 The sorting channel 14 has recessed sections 8 on both the upper and lower sides of its outlet. These recessed sections 8 are lower than the banknote conveying plane of the sorting channel 14. Therefore, when the sorting guide plate 403 swings, a portion of its front end can extend into the recessed section 8, so that the side of the sorting guide plate 403 outside the recessed section 8 is lower than the plane of the sorting channel 14. This prevents banknotes from getting stuck during transport and allows them to enter smoothly and be guided along the direction of the sorting guide plate 403. Furthermore, a clearance gap 81 needs to be provided on the side of the sorting guide plate 403 located inside the recessed section 8. The purpose of this clearance gap 81 is that when the sorting guide plate 403 swings to one side, if there are still banknotes being conveyed on that side, the clearance gap 81 will not jam the banknotes but will allow them to be conveyed smoothly through the clearance gap, thus solving to some extent the problem of banknote jamming caused by untimely banknote delivery during the swinging process.

[0045] As another embodiment, the clearance gap 81 can be precisely controlled by the control system to adapt to banknotes of different thicknesses and to avoid inaccuracies in the gap size due to mechanical errors caused by prolonged operation; see reference. Figures 10-11 Measuring elements 10 are provided on both the left and right sides of each groove 8. Each measuring element 10 has a retractable measuring rod 101 for engaging with the sorting guide plate 403. When the sorting guide plate 403 swings up and down, it presses the measuring rod 101 of the measuring element to extend or retract. The measuring rod 101 contains an elastic device 102 for support and a distance sensor 103 for detecting the extension or retraction distance of the measuring rod. When the sorting guide plate 403 abuts against the measuring rod 101 and drives its extension or retraction, the distance sensor 103 can provide feedback to the control system to know the current size of the clearance gap 81. When the sorting guide plate 403 swings to the other side, the elastic device 102 controls the measuring rod 101 to reset. The distance sensor 103 can be a micro-sensor from the prior art, or, as in this embodiment, a through-beam light sensor. Multiple sensors are arranged in a straight line, sequentially positioned away from the light-shielding plate 104. When the light-shielding plate moves, the signal changes from multiple sensors determine the insertion distance of the light-shielding plate, thus determining the moving distance of the measuring rod 101, and calculating the size of the clearance gap 81. The advantage of this embodiment is that during the long-term oscillation of the sorting guide plate 403, mechanical errors can cause the clearance gap to be poorly controlled, resulting in gaps that are too large or too small. The measuring element 10 can provide timely feedback on the size of the clearance gap, coordinating with the action of the control drive component 9 to achieve precise control of the clearance gap 81. If the gap is too large, the portion of the sorting guide plate 403 outside the groove 8 cannot accurately be lower than the plane of the sorting channel 14, causing banknotes to get stuck when entering the sorting guide plate 403. If the gap is too small, the end of the banknote may be easily caught in the groove 8 and the side of the sorting guide plate located within the groove 8 when it leaves the sorting guide plate 403, also causing a banknote jamming problem. Furthermore, due to the presence of the elastic device 102, the sorting guide plate 403 has slight swing damping after abutting the measuring element, thereby reducing the speed at the end of the swing stroke. This facilitates precise stopping of the drive component 9 and further improves the accuracy of the clearance gap 81 control. This ensures that even in complex situations where genuine and counterfeit banknotes are mixed, the sorting guide plate 403 can maintain precise positioning and achieve faster and more accurate sorting of genuine and counterfeit banknotes despite multiple switching swings.

[0046] As a supplement to another embodiment, further reference is made to Figure 1 and Figures 6-7The sorting guide plate 403 is hinged at both ends to the body 1. A drive component 9 is provided at the hinge end. The drive component 9 can be a locked servo motor or a small servo motor to control and drive the sorting guide plate 403 to swing and switch between two position states. At the other hinge end of the sorting guide plate 403, a first sensor 91 is provided. The first sensor 91 includes a light-shielding flap and a detection optical coupler. The light-shielding flap swings together with the sorting guide plate 403. The detection optical coupler is used to detect position information and determine the position state of the sorting guide plate 403 to ensure the accuracy of the position state.

[0047] As a supplement to another embodiment, further, refer to Figure 9 This banknote counter adopts a split structure for easy disassembly. Its identification mechanism 3 includes a flip-up piece 31 that can be opened relative to the identification channel 13. The lower ends of the flip-up piece 31 are hinged to the machine body 1 on both sides. A limiting member is provided at the hinge position to restrict the opening angle. A latching member 32 is provided at the upper end of the flip-up piece 31, and a connecting post 321 is provided at a corresponding position on the machine body 1. The latching groove on the latching member 32 is adapted to engage with the connecting post 321. A handle is provided on the outermost side of the flip-up piece 31. When the user moves the handle from the outside, the latching member 32 can swing, thereby releasing the engagement with the connecting post 321. The latching state is maintained by a torsion spring. This structural design allows the identification channel 13 of the banknote counter to be directly exposed to the outside, facilitating cleaning or inspection by the user. (See also...) Figure 8 The sorting mechanism 4 also includes a separable channel plate 41. The channel plate 41 has grooves 411 on both sides, and the machine body 1 has a slide rail 412 that slides in conjunction with the grooves 411. The slide rail 412 has telescopic steel balls for positioning, and the grooves 411 have holes for the steel balls to partially engage. Thus, when the channel plate 41 is inserted into the corresponding position, the telescopic steel balls engage in the holes for positioning. Therefore, when the channel plate 41 is pulled out, the sorting channel 14 can be exposed to the outside, facilitating cleaning or inspection by the user.

[0048] As a supplement to another embodiment, furthermore, since banknotes in the sorting channel 14 may travel through different exit channels due to the oscillation of the sorting guide plate 403, in order to ensure that banknotes do not jam during transport within the sorting channel 14, or to reduce the possibility of jamming, the optimal solution is to ensure that the next banknote has not yet entered the sorting guide plate 403 after the previous banknote has fully entered it. This requires the sorting channel 14 to have sufficient length to accommodate a banknote, allowing one banknote to be temporarily held within the sorting channel 14, giving sufficient time for the portion of banknotes still within the sorting guide plate and the portion still in the sorting channel to fully enter the sorting guide plate. Specifically, the sorting channel can be set to 85mm in length to accommodate the width of most banknotes. Of course, sorting channels of different lengths can also be pre-set according to the needs of different sales regions.

[0049] As a supplement to another embodiment, in order to achieve better uninterrupted automated identification of genuine and counterfeit banknotes, adjustments have also been made to the control method. Multiple sensor components and an intelligent control system are set up. The sensor components include the aforementioned first sensor, a second sensor to detect whether banknotes at the sorting channel exit have entered the sorting guide plate, and a third sensor located in the genuine banknote dispensing channel 15 and the counterfeit banknote dispensing channel 16 to detect whether banknotes have been dispensed. Both the second and third sensors can be infrared sensors. The sensor components send the banknote position information to the control system. Simultaneously, the control system is electrically connected to the drive motor 11 inside the machine body 1. The drive motor 11 drives the banknote conveying wheels such as the twisting wheel, pressing wheel, and impeller inside the banknote counter using existing transmission methods such as belts and gears. The control system is also electrically connected to the identification module, detection component 401, and drive component 9 inside the identification mechanism 3, thereby providing comprehensive control of the banknote counter and better addressing the need for continuous adjustment of the sorting guide plate position when genuine and counterfeit banknotes are mixed in. Specifically, this includes: Step S1: Obtain the authentication result of the banknote from the authentication module within the authentication institution 3. If it is a genuine banknote, continue executing the preset program of the banknote counter. The preset program ensures that the sorting guide plate 403 is positioned in the position of guiding the banknote into the genuine banknote outlet channel 15 below, and that it has a relatively high banknote conveying speed to improve counting efficiency. If it is a counterfeit banknote, proceed to step S2. Step S2: Control the drive motor 11 to reduce its speed, preferably to 80% of its normal speed. The purpose is to reduce the overall conveying speed of the banknotes, allowing sufficient time for the subsequent switching and resetting of the sorting guide plate. Then proceed to step S3. Step S3: After recognizing a counterfeit banknote, the detection component 401 receives a signal. When the detection component 401 detects a counterfeit banknote entering, it first uses the second sensor to determine whether the previous banknote has completely entered the sorting guide plate 403. If it has not completely entered, it waits for a while because the length of the sorting channel 14 is sufficient to accommodate a banknote. Therefore, there is enough time and distance for the previous banknote to completely enter the sorting channel 14. After detecting that the banknote has completely entered the sorting guide plate 403, the subsequent step S4 is executed. If no banknote is detected directly, the process proceeds directly to step S4. The control strategy of this invention does not need to consider whether the banknote has completely left the sorting guide plate 403 because of the clearance gap. Even if the banknote has not left the sorting guide plate 403, the action of the sorting guide plate 403 will not cause the banknote inside to jam.

[0050] Step S4: Determine whether the current position of the sorting guide plate 403 needs to be switched. This position information is provided by the first sensor. If the previous bill was also counterfeit, the sorting guide plate 403 does not need to be switched. If the previous bill was genuine, it needs to be switched. Control the drive unit 9 to drive the sorting guide plate 403 to switch to the position state that guides the banknote into the counterfeit bill dispensing channel. Step S5: Finally, the counterfeit banknote is detected by the banknote dispensing sensor in the counterfeit banknote dispensing channel 16, indicating that the sorting of this counterfeit banknote has been completed. The system returns to step S1 and re-identifies whether it is a genuine banknote or a counterfeit banknote. If it is a genuine banknote, the preset program is switched.

[0051] Thus, through the control of slight speed reduction and sensor components, the banknote counter can basically avoid banknote jamming even in harsh usage scenarios such as mixing genuine and counterfeit banknotes, large quantities of counterfeit banknotes, and frequent switching of the position of the sorting guide plate 403, greatly improving its reliability.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.

The measuring elements (10) include a measuring rod (101) that abuts against the sorting guide plate (403) and is retractable, an elastic device (102) for supporting the measuring rod (101), and a distance sensor (103) for detecting the extension distance of the measuring rod. The sorting guide plate (403) abuts against the measuring rod (101) and drives its extension movement. The size of the clearance gap (81) is controlled by feedback from the distance sensor (103).

6. A banknote counter according to claim 1, characterized in that: The sorting guide plate (403) is hinged on the machine body (1), and a drive component (9) is provided at its hinge end. The drive component (9) is used to drive the sorting guide plate (403) to swing to switch between two position states.

7. A banknote counter according to claim 1, characterized in that: The identification mechanism (3) includes a flip-up part (31) that can be opened relative to the identification channel (13). One end of the flip-up part (31) is hinged to the body (1), and the other end is provided with a buckle (32) that engages with the body (1). The sorting mechanism (4) includes a channel plate (41) that is separable from the sorting channel (14). The channel plate (41) has grooves (411) on both sides. The machine body (1) has a slide rail (412) that slides in cooperation with the grooves (411).

8. A banknote counter according to claim 1, characterized in that: The sorting channel (14) has different length specifications, and the length of the sorting channel (14) is at least able to accommodate one banknote.

9. A banknote counter according to claim 1, characterized in that: The system includes a sensor assembly and a control system. The sensor assembly includes a first sensor for detecting the position of the sorting guide plate (403), a second sensor for detecting whether banknotes at the exit of the sorting channel (14) have entered the sorting guide plate (403), and a third sensor located in the genuine banknote dispensing channel (15) and the counterfeit banknote dispensing channel (16) for detecting whether banknotes have been dispensed. The control system is electrically connected to the drive motor inside the body (1), the control system is electrically connected to the identification module inside the identification mechanism (3), the control system is electrically connected to the detection component (401), and the control system is electrically connected to the sensor assembly.

10. A banknote counter according to claim 9, characterized in that: The control system is configured with a control strategy, which includes: Step S1: Obtain the authentication result of the banknote by the authentication module in the authentication agency (3). If it is a genuine banknote, keep the preset program of the banknote counter running; if it is a counterfeit banknote, proceed to step S2. Step S2: Control the drive motor to reduce its speed, thereby reducing the banknote conveying speed; Step S3: Obtain the signal from the detection component (401). When the detection component (401) detects counterfeit banknotes entering, determine whether there are banknotes at the exit of the sorting channel (14) that have not yet fully entered the sorting guide plate (403). If there are, wait for the banknotes to fully enter the sorting guide plate (403) before proceeding to step S4. If not, proceed directly to step S4. Step S4: Determine whether the current position of the sorting guide plate (403) needs to be switched. If so, control the sorting guide plate (403) to switch to the position state that guides the banknotes into the counterfeit banknote dispensing channel. Step S5: The counterfeit banknote dispensing sensor of the counterfeit banknote dispensing channel (16) detects the dispensing of counterfeit banknotes and returns to step S1.
