Description

Technical Field

[0001] This utility model relates to the field of banknote recognition technology, specifically an adjustable multi-currency automatic recognition and classification storage mechanism. Background Technology

[0002] The multi-currency automatic recognition device integrates high-definition image recognition, optical character recognition, and multi-sensor detection technologies. It captures features such as banknote texture and denomination numbers through a high-resolution camera, extracts denomination characters using OCR technology, and detects material characteristics using magnetic and infrared sensors to quickly match the denomination features of more than 50 mainstream currencies in the built-in database.

[0003] However, existing multi-currency automatic recognition systems often encounter problems when banknotes are inserted into the equipment. Due to their thinness (typically ≤0.15mm), smooth surface, and susceptibility to static electricity, banknotes are prone to stacking due to excessive user input or static adsorption. Most existing devices rely on traditional friction separation methods, using friction between conveyor rollers or belts at fixed intervals. For new or smooth banknotes, insufficient friction can lead to separation failure. For old, wrinkled, or curled banknotes, over-reliance on friction can exacerbate paper damage and cause channel blockage. Furthermore, when stacked banknotes directly enter the recognition area, key features such as patterns, watermarks, and anti-counterfeiting marks captured by the image recognition module are obscured, drastically increasing the feature extraction failure rate and severely impacting the accuracy of denomination determination. Therefore, we propose an adjustable multi-currency automatic recognition and sorting mechanism to address these issues. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-6 This utility model provides a technical solution: an adjustable multi-currency automatic identification and classification storage mechanism, including a body 1. The body 1 is internally equipped with a first conveying device 2 for conveying currency. A second conveying device 3 for conveying banknotes is located below the first conveying device 2. A third conveying device 4 for conveying coins is located below the second conveying device 3. An inclined plate 5 for guiding currency is fixedly connected between the two vertical plates on both sides of the body 1. The left end of the inclined plate 5 is in contact with the surface of the first conveying device 2, thereby effectively preventing currency from getting stuck in the gap. The right end of the inclined plate 5 is located above the second conveying device 3. Mounting plates 6 for support are fixedly connected to the upper surface of the two vertical plates on both sides of the body 1. Two fixing plates 7 for support are fixedly connected to the lower surface of the mounting plates 6. A conveying roller 8 is arranged between the two fixing plates 7. The conveying roller 8 is hollow inside.

[0035] The right end of the conveyor roller 8 is fixedly connected to a first connecting pipe 9 that communicates with the interior for gas flow. The right side fixing plate 7 is rotatably sleeved on the outside of the first connecting pipe 9. The left end of the conveyor roller 8 is fixedly and rotatably connected to a support shaft 10 for support. The support shaft 10 rotatably penetrates into the interior of the conveyor roller 8. The support shaft 10 and the left side fixing plate 7 are fixedly connected. The surface of the conveyor roller 8 is provided with an air intake 12 for adsorbing banknotes. The end of the support shaft 10 located inside the conveyor roller 8 is fixedly connected to an arc-shaped plate 11 for blocking the air intake 12. The right side surface of the machine body 1 is provided with an adsorption component for improving suction. The upper end of the right side fixing plate 7 penetrates through the upper surface of the mounting plate 6. The surface of the right side fixing plate 7 is provided with a drive component for rotating the conveyor roller 8. Through the cooperation between the adsorption component, the drive component and the conveyor roller 8, it is convenient to adsorb banknotes located on the upper side of the inclined plate 5. Thus, when the conveyor roller 8 is subsequently conveyed, the airflow is blocked by the arc-shaped plate 11 to move a single banknote to the upper side of the second conveying device 3.

[0036] The adsorption assembly includes a suction fan 13, which is fixedly connected to the right side surface of the body 1. The input end of the suction fan 13 is fixedly connected to a second connecting pipe 14 for airflow. The first connecting pipe 9 rotatably passes through the interior of the body 1. A rotating flange 15 is provided between the second connecting pipe 14 and the first connecting pipe 9 to connect the two pipes. The rotating flange 15 ensures the stability and sealing of the connection between the first connecting pipe 9 and the second connecting pipe 14.

[0037] In the above embodiments, the suction fan 13 is also equipped with a power supply, wires, controller, and microcomputer. The airflow can be adjusted through external control components, so that the airflow can smoothly adsorb single banknotes. The micro differential pressure sensor is used to monitor the air pressure at the suction port in real time and convert it into an electrical signal. After receiving the signal, the microcontroller calculates the deviation between the current airflow and the target value, and then outputs a PWM signal through a PID algorithm. The fan driver changes the fan speed accordingly to adjust the airflow (decreases speed when strong and increases speed when weak). At the same time, the user can preset the target airflow and view the real-time status through buttons or the screen, ultimately ensuring that the airflow is stable at the target value adapted to the characteristics of the banknote, and achieving precise control of single-note peeling.

[0038] The drive assembly includes a motor 16, which is fixedly connected to the surface of the right-side fixed plate 7. The right-side fixed plate 7 is hollow inside, and the output shaft of the motor 16 rotates through the interior of the fixed plate 7. The output shaft of the motor 16 and the end of the first connecting pipe 9 located inside the fixed plate 7 are both fixedly fitted with synchronous pulleys 17 for transmission. The two synchronous pulleys 17 are externally meshed with a synchronous belt 18 for use with the two synchronous pulleys 17. By starting the motor 16 and the transmission of the two synchronous pulleys 17 and the synchronous belt 18, the rotation of the first connecting pipe 9 can be driven. Through the cooperation between the synchronous pulleys 17 and the synchronous belt 18, the stability and synchronization of the transmission are effectively improved.

[0039] In the above embodiments, the motor 16 is also equipped with a power supply, wires, a controller, and a microcomputer, etc. Since these are not the main structures, they will not be described in detail here.

[0040] The upper surface of the inclined plate 5 is fixedly connected with a stop 19 for blocking the banknotes. The stop 19 prevents the banknotes from passing under the conveyor roller 8. At the same time, the stop 19 allows the banknotes to slide smoothly onto the upper side of the second conveyor device 3. The upper surface of the inclined plate 5 is fixedly connected with two baffles 20 for limiting the banknotes. Both baffles 20 are rotatably sleeved on the outside of the conveyor roller 8. The baffles 20 guide the banknotes, thereby ensuring the adsorption effect of the subsequent conveyor roller 8 on the banknotes.

[0041] The surface of the inclined plate 5 is provided with a through hole 21 for coins to pass through. The through hole 21 facilitates the falling of mixed coins. A fixed bucket 22 for guiding coins is fixedly connected between the two vertical plates of the machine body 1. The feeding end of the fixed bucket 22 is located on the upper side of the third conveying device 4. The fixed bucket 22 facilitates the conveying of the screened coins to the upper side of the third conveying device 4.

[0042] In the above embodiment, there is a certain distance between the fixed bucket 22 and the third conveying device 4, which facilitates the passage of coins.

[0043] Two identification modules 23 for automatic currency identification are fixedly connected between the two vertical plates on both sides of the main body 1. The two identification modules 23 are located on the upper side of the second conveying device 3 and the third conveying device 4, respectively. With the setting of the identification modules 23, when the currency enters the identification area, the identification modules 23 can collect the feature information of the currency and compare and analyze it with the information in the database to quickly determine the type, denomination and authenticity of the currency.

[0044] The upper side of the third conveying device 4 is provided with a horizontal plate 25 for support. The horizontal plate 25 is fixedly connected between the two vertical plates of the machine body 1. The lower side of the horizontal plate 25 is fixedly connected with an electric push rod 26. The lower end of the electric push rod 26 is fixedly connected with a push plate 27. Through the cooperation between the electric push rod 26 and the push plate 27, the height of the push plate 27 can be easily adjusted, thereby flattening the stacked coins and ensuring the recognition effect of the subsequent recognition module 23 on the coins.

[0045] Two sorting boxes 24 for collecting sorted currency are fixedly connected between the two vertical plates on both sides of the main body 1. The two sorting boxes 24 are located under the second conveying device 3 and the third conveying device 4, respectively. The sorting boxes 24 facilitate the collection of sorted banknotes and coins.

[0046] Working principle:

[0047] In use, this adjustable multi-currency automatic identification and sorting mechanism works by placing currency on the upper side of the first conveyor device 2. Then, three conveyor belts are activated, and the movement of the first conveyor device 2 causes the currency to flow towards the upper side of the inclined plate 5. The inclined plate then allows the currency to slide down to the front of the conveyor roller 8. The suction fan 13 is then activated, and the cooperation between the suction fan 13, the second connecting pipe 14, the rotating flange 15, the first connecting pipe 9, the conveyor roller 8, and the suction port 12 allows for the adsorption of individual banknotes. The start motor 16, along with the two synchronous pulleys 17 and the synchronous belt 18, drives the rotation of the first connecting pipe 9. With the cooperation of the rotating flange 15, the first connecting pipe 9 and the second connecting pipe 14 can maintain a stable connection. The rotation of the first connecting pipe 9 drives the rotation of the conveying roller 8. When the banknote is sucked to the right side, the suction port 12 will be blocked by the arc plate 11. At this time, the banknote will no longer be sucked up and will fall onto the upper side of the second conveying device 3, thereby improving the subsequent banknote recognition effect.

[0048] Meanwhile, with the through hole 21, the coins will fall into the inside of the fixed hopper 22 and then from the inside of the fixed hopper 22 to the upper side of the third conveyor 4. Subsequently, with the cooperation of the push plate 27, the stacked coins will be flattened, thereby ensuring the subsequent recognition effect of the coins.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
