Description

Technical Field

[0001] This invention relates to the field of financial terminal technology, and in particular to a banknote processing device. Background Technology

[0002] As a key piece of equipment in the cash circulation process, banknote processing equipment undertakes important functions such as receiving, identifying, counting, sorting, and storing banknotes. With the continuous development of automation technology, the design of banknote processing equipment increasingly focuses on efficiency, accuracy, and user-friendliness to meet the needs of various application scenarios such as banks, self-service terminals, and retail.

[0003] Currently, most mainstream banknote processing equipment on the market has a relatively simple connection channel design, typically equipped with only one or two fixed connection channels. This design limits the flexible configuration and expandability between internal modules, especially the banknote transport path between the lower banknote collection module and the upper processing unit. To achieve efficient banknote transport, the lower banknote collection module often requires an additional dedicated transport channel, which not only increases the manufacturing cost of the equipment but also makes the equipment structure more complex. Even more inconvenient is that during module maintenance or banknote retrieval operations, operators must manually open these channels. This process is not only time-consuming and labor-intensive but may also lead to equipment damage or banknote loss due to improper operation, reducing overall operational convenience and security.

[0004] During the banknote transmission process, gaps or misalignments inevitably occur between the upper and lower modules due to factors such as assembly errors, equipment vibration, or deviations in module installation positions. If the connecting channel cannot achieve effective fit and precise alignment with the upper and lower modules, banknotes are prone to jamming when passing through the connection point due to uneven force and deviation in their trajectory. Summary of the Invention

[0005] This invention provides a banknote processing device to solve the problems of existing banknote processing devices that require additional transfer channels for the collection module and manual folding of the channels for the pick-up and drop-off modules, which are costly and cumbersome to operate. In addition, the poor docking accuracy can easily lead to banknote jamming. The invention achieves precise connection between the banknote transmission channel of the upper module and the banknote storage section of the lower module.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0036] The following is combined with Figures 1 to 12 The banknote processing equipment provided in this invention will be described in detail through specific embodiments and application scenarios.

[0037] In the embodiments of the invention, such as Figures 1 to 3 As shown, the banknote processing equipment 1 includes an upper module 10, a lower module 20, and a multi-channel connection device 30. The upper module 10 is provided with a banknote transmission channel 11. The lower module 20 is stacked vertically with the upper module 10, and a banknote storage section 21 is provided inside the lower module 20. The multi-channel connection device 30 is located between the upper module 10 and the lower module 20 and is used to connect the banknote transmission channel 11 and the banknote storage section 21. The multi-channel connection device 30 includes at least one channel connection unit 31. The channel connection unit 31 has retractable mating teeth, which are configured to extend during banknote transmission to engage with the upper module 10 and / or the lower module 20, and retract during equipment maintenance to disconnect the connection.

[0038] The banknote transmission channel 11 provides the basic path for the transmission of banknotes within the upper module 10. It is the necessary path for banknotes to go from entering the device to being distributed to each banknote dispensing slot 12, ensuring that banknotes can flow in an orderly manner within the upper module 10. It is the starting transmission link of the entire banknote processing flow, enabling banknotes to be processed in accordance with the preset process.

[0039] The lower module 20 and the upper module 10 are stacked vertically, which saves space and makes the device more compact. At the same time, the stacking arrangement facilitates the installation and connection of the multi-channel connection device 30 between the two, providing a reasonable spatial structure for the transfer of banknotes between the upper module 10 and the lower module 20.

[0040] The banknote storage unit 21 is used to store or classify banknotes.

[0041] The multi-channel connection device 30 is located between the upper module 10 and the lower module 20, serving as a bridge between the upper module 10 and the lower module 20. It provides a physical channel for the smooth transmission of banknotes, enabling banknotes to flow stably and efficiently between the upper and lower modules.

[0042] The channel connection unit 31 is the execution unit of the multi-channel connection device 30 to realize the connection function. A single unit can meet the connection requirements of a group of transmission channels and storage units, and can be configured with at least one banknote processing scale that can adapt to different devices (single channel adapts to a small amount of storage, multi-channel adapts to multi-class storage), providing flexible adaptability for the device to adapt to different scenarios.

[0043] The mating teeth are configured to extend during banknote transmission to engage with the upper module 10 and / or the lower module 20. By extending and engaging with the upper and lower modules through the engagement of the mating teeth, the mating gap between the connecting unit and the upper and lower modules is eliminated, so that the upper banknote transmission channel 11 and the lower banknote storage section 21 form a complete banknote transmission channel without any gaps, ensuring the stability of the banknote transmission trajectory and avoiding banknote deviation and jamming.

[0044] The mating teeth are configured to retract to disconnect the connection during equipment maintenance. The retraction of the mating teeth can quickly release the mechanical engagement between the channel connection unit 31 and the upper and lower modules. The upper and lower modules can be easily separated without the need for additional disassembly of the connection device or dedicated channel. This facilitates banknote counting, equipment maintenance, and component replacement by operators, reducing maintenance time and improving maintenance efficiency.

[0045] This application provides a multi-channel connection device 30 between the upper module 10 and the lower module 20. The mating teeth of the channel connection unit 31 extend during banknote transmission and engage with the upper module 10 and / or the lower module 20, thereby achieving precise communication between the banknote transmission channel 11 of the upper module 10 and the banknote storage section 21 of the lower module 20. At the same time, the mating teeth are retractable, and during maintenance, the mating teeth retract to disconnect the connection, allowing for convenient separation of the upper and lower modules without additional disassembly and assembly, thus improving the maintenance efficiency of the device. The precise communication achieved by the extended engagement of the mating teeth can prevent banknote transmission from being obstructed due to channel alignment deviations, and at the same time reduce the possibility of banknote jamming.

[0046] Reference Figures 1 to 3 According to the present invention, a banknote processing device 1 has a banknote transmission channel 11 of the upper module 10 with a plurality of banknote sorting ports 12 and a banknote storage section 21 of the lower module 20 with a plurality of banknote inlets 22, the plurality of banknote inlets 22 being correspondingly arranged with the plurality of banknote sorting ports 12; the multi-channel connection device 30 includes a plurality of channel connection units 31, the plurality of channel connection units 31 being respectively connected between the plurality of banknote sorting ports 12 and the plurality of banknote inlets 22.

[0047] Understandably, the multiple banknote sorting slots 12 serve two purposes. First, they connect to the banknote transmission channel 11, sorting the banknotes in the channel according to different classification criteria (such as denomination, condition, etc.), allowing different categories of banknotes to enter their respective channel connection units 31 and then be transmitted to different banknote storage sections 21 in the lower module 20. Second, the multiple banknote sorting slots 12 provide a basis for multi-channel parallel banknote transmission, enabling the simultaneous processing of multiple banknotes and improving the equipment's processing efficiency.

[0048] Multiple banknote storage sections 21 are used to store different types of banknotes transmitted from the upper module's 10-cent banknote slot 12. The multiple banknote storage sections 21 can be classified and stored according to actual needs, such as by denomination, currency type, or banknote condition, to facilitate subsequent banknote management, counting, and use.

[0049] The banknote inlets 22 of multiple banknote storage units 21 are configured one-to-one with the banknote dispensing inlets 12, ensuring that each banknote dispensed from the upper module 10 accurately enters the corresponding banknote storage unit 21 in the lower module 20, achieving precise banknote transfer. This avoids incorrect banknote storage and improves the accuracy and efficiency of banknote processing.

[0050] Multiple channel connection units 31, each independently responsible for connecting a set of banknote inlets 12 and banknote feed inlets 22, realize multi-path parallel banknote transmission. The existence of multiple channel connection units 31 enables the equipment to process multiple banknote transmissions simultaneously, greatly improving the overall processing capacity of the equipment and meeting the requirements for multi-channel synchronous and efficient banknote transmission.

[0051] Reference Figures 1 to 3 According to a banknote processing device 1 provided by the present invention, a first channel tooth 13 is provided on the outer periphery of the banknote sorting port 12, and a second channel tooth 23 is provided on the outer periphery of the banknote inlet 22; the channel connecting unit 31 has a first port and a second port, a first mating tooth 311 is provided on the circumferential direction of the first port, the first mating tooth 311 is configured to extend to engage with the first channel tooth 13, and a second mating tooth 312 is provided on the circumferential direction of the second port, the second mating tooth 312 is configured to extend to engage with the second channel tooth 23.

[0052] Understandably, the first port is used to connect to the banknote sorting port 12 of the upper module 10, and the second port is used to connect to the banknote inlet 22 of the lower module 20. The two ports are interconnected to form an internal channel for banknote transmission. This internal channel is the specific path for banknotes to be transmitted between the upper and lower modules, ensuring that banknotes can be smoothly transmitted from one module to another.

[0053] The first port has a retractable first mating tooth 311 in its circumferential direction. When it engages with the first channel tooth 13 of the banknote dispensing port 12 of the upper module 10, the retractable feature allows the first mating tooth 311 to be adjusted in length and width according to actual conditions. During connection, the first mating tooth 311 extends and engages tightly with the first channel tooth 13 to achieve a stable connection between the channel connection unit 31 and the upper module 10. When the equipment needs maintenance, the first mating tooth 311 can retract to quickly disconnect from the upper module 10, facilitating the separation of the upper and lower modules and improving the maintenance efficiency of the device.

[0054] The second port has a retractable second mating tooth 312 in its circumferential direction. Similar to the first mating tooth 311, the retractable nature of the second mating tooth 312 allows it to extend or retract as needed when it engages with the second channel tooth 23 of the banknote inlet 22 of the lower module 20. This ensures a stable connection between the channel connection unit 31 and the lower module 20 during connection, and facilitates disconnection during maintenance, allowing for easy separation of the upper and lower modules and improving maintenance convenience.

[0055] The floating cross-fitting of the first mating tooth 311 with the first channel tooth 13, and the floating cross-fitting of the second mating tooth 312 with the second channel tooth 23, effectively compensates for the mating gaps and misalignments caused by assembly errors, equipment vibration, or module installation position deviations between the upper and lower modules. During banknote transmission, this floating structure ensures that the banknotes are subjected to uniform force at the connection points and have a stable trajectory, preventing jamming due to uneven force or trajectory deviation, thereby reducing the possibility of banknote jamming and improving the reliability and stability of the equipment.

[0056] Reference Figure 2 and Figure 3According to a banknote processing device 1 provided by the present invention, a multi-channel connecting device 30 has a first working state and a second working state. When the multi-channel connecting device 30 is in the first working state, the first mating tooth 311 and the second mating tooth 312 extend toward their respective corresponding first channel tooth 13 and second channel tooth 23, and cross-fit with the corresponding first channel tooth 13 and second channel tooth 23 to connect the first port to the banknote sorting port 12 and the second port to the banknote inlet port 22. When the multi-channel connecting device 30 is in the second working state, the first mating tooth 311 and the second mating tooth 312 retract to separate the multi-channel connecting device 30 from the upper module 10 and the lower module 20.

[0057] Understandably, when the multi-channel connection device 30 is in its first operating state, the first mating tooth 311 and the second mating tooth 312 extend toward their respective first channel tooth 13 and second channel tooth 23, and engage with them crosswise. This ensures accurate and error-free connection between the first port of the channel connection unit 31 and the banknote sorting port 12 of the upper module 10, and between the second port and the banknote inlet 22 of the lower module 20. Each channel connection unit 31 independently handles the connection of a set of banknote sorting ports 12 and banknote inlet 22, forming a multi-path parallel banknote transmission channel. This allows different types of banknotes to be accurately and error-free transmitted from the upper module 10 to the corresponding banknote storage section 21 of the lower module 20 according to preset classification standards, meeting the requirements for banknote classification storage and accurate transmission.

[0058] The cross-fitting structural design increases the stability and reliability of the connection. The tight engagement between the first mating tooth 311 and the first channel tooth 13, and between the second mating tooth 312 and the second channel tooth 23, effectively prevents loosening or detachment during banknote transmission. This stable connection method ensures that the banknote maintains a stable trajectory during transmission, avoiding problems such as banknote jamming or deviation caused by unstable connections, thus guaranteeing the smoothness and efficiency of banknote transmission.

[0059] When the equipment requires maintenance, cleaning, repair, or component replacement, the multi-channel connection device 30 is switched to its second operating state. The first mating tooth 311 and the second mating tooth 312 retract, quickly disconnecting the multi-channel connection device 30 from the upper module 10 and the lower module 20. This allows operators to easily separate the upper and lower modules without using complex tools or performing cumbersome disassembly operations, significantly saving maintenance time and labor costs.

[0060] Traditional banknote processing equipment often requires disassembling numerous components to access the parts needing maintenance, which not only increases the difficulty and risk of maintenance but also easily leads to equipment damage. This embodiment achieves module separation through a retractable mating tooth operation, reducing the difficulty and complexity of maintenance. This allows operators to perform equipment maintenance more conveniently and quickly, improving the maintainability and lifespan of the equipment.

[0061] Reference Figures 4 to 9 According to a banknote processing device 1 provided by the present invention, the first docking tooth 311 includes a first docking main tooth portion 3111 and a first docking secondary tooth portion 3112 arranged opposite to each other along the channel width direction, with a gap between the first docking main tooth portion 3111 and the first docking secondary tooth portion 3112 to form a first pair of interfaces for banknotes to pass through; the second docking tooth 312 includes a second docking main tooth portion 3121 and a second docking secondary tooth portion 3122 arranged opposite to each other along the channel width direction, with a gap between the second docking main tooth portion 3121 and the second docking secondary tooth portion 3122 to form a second pair of interfaces for banknotes to pass through.

[0062] It is understood that the first mating tooth 311 includes a first mating main tooth 3111 and a first mating auxiliary tooth 3112 that are opposite each other along the channel width direction, and the second mating tooth 312 includes a second mating main tooth 3121 and a second mating auxiliary tooth 3122 that are opposite each other along the channel width direction. In this way, a bidirectional limiting structure is constructed from the channel width direction. The main tooth and auxiliary tooth form supports on both sides of the channel, respectively. When they cross-fit with the first channel tooth 13 and the second channel tooth 23 of the upper and lower modules, they can limit the offset of the mating teeth from the width direction, avoid misalignment of the mating teeth due to external forces during banknote transfer (such as banknote friction and equipment vibration), further enhance the stability of the multi-channel connection device 30 and the upper and lower modules, and ensure that the docking state is continuously reliable.

[0063] A gap is left between the main tooth section and the auxiliary tooth section, forming the first pair of interfaces and the second pair of interfaces for banknotes to pass through. While ensuring a stable connection, precise space is reserved for banknote transmission. On the one hand, the size of the gap can adapt to the width of common banknotes, ensuring smooth passage and preventing banknotes from getting stuck due to an excessively narrow channel or shifting due to an excessively wide channel. On the other hand, the interface serves as a directional guide channel for banknotes at the connection point, receiving banknotes output from the upper module's 10-cent banknote slot 12 and precisely guiding them to the lower module's 20-cent banknote inlet 22. This prevents banknotes from shifting or wrinkling during the connection transition, ensuring the smoothness of the entire banknote transmission path and further reducing the risk of banknote jamming.

[0064] Reference Figures 4 to 9According to a banknote processing device 1 provided by the present invention, the channel connection unit 31 includes a channel support 32 and a movable frame 33, the movable frame 33 being movably connected to the channel support 32; the second docking tooth 312 further includes a first rotating shaft 3123 and a first resetting member 3124, the second docking main tooth 3121 and the second docking auxiliary tooth 3122 are both connected to the movable frame 33, the movable frame 33 being rotatably connected to the channel support 32 via the first rotating shaft 3123; the first resetting member 3124 is sleeved on one end of the first rotating shaft 3123, the first rotating shaft 3123 can drive the movable frame 33 and the second docking main tooth 3121 and the second docking auxiliary tooth 3122 to rotate, so as to realize the extension or retraction of the second docking tooth 312; the first resetting member 3124 is used to drive the second docking tooth 312 to reset and retract after the second docking tooth 312 completes the extension action.

[0065] Understandably, the movable frame 33 is movably connected to the channel support 32, and both the second mating main tooth 3121 and the second mating auxiliary tooth 3122 are connected to the movable frame 33. The movable frame 33 is rotatably connected to the channel support 32 via the first rotating shaft 3123. This allows the second mating tooth 312 to rotate around the first rotating shaft 3123, thereby extending or retracting. When the device needs to transmit banknotes normally, the first rotating shaft 3123 drives the movable frame 33 and the second mating tooth 312 to rotate and extend, so that the second mating tooth 312 accurately cross-fits with the first channel tooth 13 of the upper module 10, establishing a stable banknote transmission channel 11, ensuring that banknotes can be smoothly transmitted from the upper module 10 to the channel connection unit 31.

[0066] When the equipment requires maintenance, repair, or separation of the upper and lower modules, the first rotating shaft 3123 rotates in the opposite direction, causing the movable frame 33 and the second mating tooth 312 to retract. This allows the equipment to quickly adjust its state according to different work requirements, improving the ease of operation and flexibility of the equipment.

[0067] When the device does not need to transfer cash (such as when it enters maintenance mode) and the external driving force disappears, the first reset component 3124 (such as a torsion spring or tension spring) can drive the first rotating shaft 3123 to rotate in the opposite direction through the force released by its own elastic deformation, thereby driving the movable frame 33 and the docking teeth to retract. The reset can be completed without manual operation, which simplifies the state switching process and ensures the consistency of the retraction position of the docking teeth, providing convenience for the separation of the upper and lower modules.

[0068] The design of the movable frame 33 and the first rotating shaft 3123 allows the extension and retraction of the second mating tooth 312 to be completed within a limited space, without occupying too much internal space of the equipment, thus improving the space utilization of the equipment and enabling the equipment to achieve more functions in a more compact space.

[0069] Reference Figure 11 and Figure 12 According to a banknote processing device 1 provided by the present invention, one end of the channel support 32 is provided with a push rod linkage mechanism 34 and a pressure plate 35. The pressure plate 35 is connected to the front end of the push rod linkage mechanism 34, and the rear end of the push rod linkage mechanism 34 is linked with the safe door of the device. The second docking tooth 312 also includes a floating wheel 3125. The floating wheel 3125 is eccentrically arranged with the first rotating shaft 3123. The pressure plate 35 can move and press against the floating wheel 3125. When the safe door is closed, the push rod linkage mechanism 34 is pushed forward, and the pressure plate 35 moves forward and presses down on the floating wheel 3125. The floating wheel 3125 drives the first rotating shaft 3123 to rotate, thereby driving the second docking main tooth 3121 and the second docking auxiliary tooth 3122 to extend.

[0070] Understandably, the rear end of the push rod linkage mechanism 34 is linked to the safe door of the equipment. When the safe door is closed, it triggers the push rod linkage mechanism 34 to push forward. This tightly links the state of the safe door with the movement of the second mating tooth 312, forming a safety protection mechanism. The second mating tooth 312 will only extend when the safe door is closed, ensuring that the banknote transmission channel 11 can be properly established when the equipment is in a safe protection state. This prevents banknote transmission operations from occurring when the equipment is not in a safe protection state, thus ensuring the safety of both the equipment and the banknotes.

[0071] Operators only need to close the safe door; there is no need to manually extend the second docking tooth 312. The equipment will automatically complete the channel connection, simplifying the operation process and improving efficiency.

[0072] The pressure plate 35 is connected to the front end of the push rod linkage mechanism 34. When the push rod linkage mechanism 34 pushes forward, the pressure plate 35 moves forward and presses down on the floating wheel 3125. The floating wheel 3125 is eccentrically positioned with respect to the first rotating shaft 3123. This eccentric structure allows the floating wheel 3125 to generate a torque that causes the first rotating shaft 3123 to rotate when it is pressed down by the pressure plate 35. Through the precise cooperation between the pressure plate 35 and the floating wheel 3125, the linear motion of the push rod linkage mechanism 34 can be accurately converted into the rotational motion of the first rotating shaft 3123, thereby driving the second mating main tooth 3121 and the second mating auxiliary tooth 3122 to extend, achieving precision and reliability in power transmission.

[0073] Reference Figures 4 to 9According to a banknote processing device 1 provided by the present invention, the first docking tooth 311 further includes a second rotating shaft 3113, a third rotating shaft 3114, a second resetting member 3115, and a third resetting member 3116; the first main docking tooth 3111 is connected to the second rotating shaft 3113, the first secondary docking tooth 3112 is connected to the third rotating shaft 3114, and both the second rotating shaft 3113 and the third rotating shaft 3114 are rotatably connected to the channel support 32; the second resetting member 3115 is connected between the end of the second rotating shaft 3113 and the channel support 32, and the third resetting member 3116 is connected between the end of the third rotating shaft 3114 and the channel support 32; the second resetting member 3115 and the third resetting member 3116 are used to provide elastic force to keep the first main docking tooth 3111 and the first secondary docking tooth 3112 in an outwardly extended state.

[0074] Understandably, the first main docking tooth 3111 is connected to the second rotating shaft 3113, and the first auxiliary docking tooth 3112 is connected to the third rotating shaft 3114, with both the second and third rotating shafts rotatably connected to the channel support 32. This allows the first main docking tooth 3111 and the first auxiliary docking tooth 3112 to rotate flexibly around their respective rotating shafts. When the equipment is running, the first main docking tooth 3111 and the first auxiliary docking tooth 3112 can accurately interlock with the second channel tooth 23 of the upper module 10, forming a stable and reliable banknote transmission channel 11.

[0075] The second reset member 3115 is connected between the end of the second rotating shaft 3113 and the channel support 32, and the third reset member 3116 is connected between the end of the third rotating shaft 3114 and the channel support 32. These two reset members provide elastic force, ensuring that the first mating main tooth 3111 and the first mating secondary tooth 3112 always remain in an outwardly extended state. The automatic reset function eliminates the need for manual operation, greatly improving the automation level and operational efficiency of the equipment.

[0076] Reference Figures 4 to 9 According to the banknote processing device 1 provided by the present invention, the channel connecting unit 31 further includes a power component 313 symmetrically arranged along the width direction of the channel. The power component 313 includes at least one power wheel 3131, a power shaft 3132, and a power transmission gear set 3133. The power wheel 3131 is fixedly sleeved on the power shaft 3132, and the power shaft 3132 is fixed on the channel support 32. The power transmission gear set 3133 is connected to the channel support 32 and is located at one end of the power shaft 3132 along its own axial direction. The power transmission gear set 3133 is drively connected to the power shaft 3132. The first mating main tooth portion 3111 and the first mating secondary tooth portion 3112 are provided with clearance notches. The clearance notches are used to allow the power wheel 3131 to extend into the internal channel of the channel connecting unit 31 to drive the banknotes to be transmitted in the channel.

[0077] Understandably, the power assembly 313 includes at least one power wheel 3131, a power shaft 3132, and a power transmission gear set 3133. The power wheel 3131 is fixedly mounted on the power shaft 3132, which in turn is fixed to the channel support 32, ensuring that the power wheel 3131 maintains a stable position and orientation during operation. The power transmission gear set 3133 is connected to the channel support 32 and is drive-connected to the power shaft 3132. Through precise transmission of the gear set, power can be smoothly transmitted to the power wheel 3131. When the power wheel 3131 rotates, it generates continuous and stable friction, providing reliable power support for the transmission of banknotes within the channel and ensuring that the banknotes can move smoothly at a predetermined speed and direction.

[0078] Reference Figure 10 According to the banknote processing device 1 provided by the present invention, the power components 313 of two adjacent channel connection units 31 are connected by a transmission belt 36 to realize the synchronous transmission of multiple power components 313.

[0079] Understandably, in the banknote processing equipment 1, multiple channel connection units 31 work together to complete the banknote transmission task. When the power components 313 of two adjacent channel connection units 31 are connected by a transmission belt 36 to achieve synchronous transmission, it can be ensured that the magnitude and direction of the power output by each power component 313 are consistent. In this way, the driving force received by the banknote when passing through different channel connection units 31 is uniform and stable, avoiding problems such as banknote deviation, jamming, or wrinkling during transmission due to inconsistent power, thereby ensuring the smoothness and accuracy of banknote transmission.

[0080] Using a drive belt 36 to connect adjacent power components 313 offers advantages over complex gear drives or other transmission methods. The drive belt 36 is simple in structure and easy to install. This simplifies the equipment's transmission structure, making the overall layout more compact and rational, saving internal space, and facilitating miniaturization and integrated design.

[0081] When the banknote processing equipment 1 needs to be expanded or upgraded, for example, by increasing the number of channel connection units 31 to improve the processing capacity of the equipment, the power assembly 313 can be easily synchronized with the new unit by using the drive belt 36 to connect it. Simply connect the new power assembly 313 to the existing power assembly 313 via the drive belt 36 and perform appropriate adjustments to enable the new unit to work collaboratively with the existing unit. This eliminates the need for large-scale modifications to the overall transmission system of the equipment, reducing the difficulty and cost of equipment expansion and upgrades.

[0082] Reference Figures 10 to 12According to the banknote processing device 1 provided by the present invention, the multi-channel connection device 30 further includes a first main support 37 and a second main support 38, which are arranged side by side and spaced apart; a plurality of channel connection units 31 are spaced apart between the first main support 37 and the second main support 38 and are fixedly connected to the first main support 37 and the second main support 38; a push rod linkage mechanism 34 is disposed on the first main support 37 and can be pushed and pulled along the length direction of the first main support 37; a position sensor 39 is provided on the rear end of the push rod linkage mechanism 34, which is used to detect the pushing and pulling displacement of the push rod linkage mechanism 34 to determine whether the extension of the first mating tooth 311 is in place.

[0083] Understandably, the first main support 37 and the second main support 38 are arranged side by side and spaced apart, forming a stable frame structure. This structure can withstand the weight of components such as the channel connection unit 31 and the push rod linkage mechanism 34, as well as various forces generated during banknote transmission, providing a solid foundation for the entire multi-channel connection device 30, preventing the device from shaking or deforming, and ensuring the normal operation of the equipment.

[0084] Multiple channel connection units 31 are spaced apart between the first main support 37 and the second main support 38, and are fixedly connected to both. This ensures that the force on the channel connection unit 31 is evenly distributed across the two main supports, preventing support damage or structural failure due to excessive local stress. Simultaneously, even force distribution also helps improve the overall stability and reliability of the equipment, extending its service life.

[0085] The push rod linkage mechanism 34 is mounted on the first main support 37 and can be pushed and pulled along the length of the first main support 37. The first main support 37 provides a stable motion track for the push rod linkage mechanism 34, ensuring that the push rod linkage mechanism 34 can maintain linear motion during the pushing and pulling process without deviation or jamming. This helps to improve the working accuracy and reliability of the push rod linkage mechanism 34, thereby achieving precise coordinated action with the first mating tooth 311.

[0086] The positioning sensor 39 is located at the rear end of the push rod linkage mechanism 34 and is used to detect the pushing and pulling displacement of the push rod linkage mechanism 34. By accurately measuring the displacement, the positioning sensor 39 can determine whether the extension of the second mating tooth 312 is in place. This allows the equipment to precisely control the extension position and degree of the second mating tooth 312 according to actual needs, ensuring that the second mating tooth 312 can accurately mate with the second channel tooth 23 of the lower module 20, thereby achieving smooth transfer of banknotes.

[0087] The positioning sensor 39 can monitor the displacement of the push rod linkage mechanism 34 in real time and feed the detection signal back to the equipment control system. If the second mating tooth 312 does not extend properly or an abnormality occurs, the control system can quickly determine the location and cause of the fault based on the feedback information from the positioning sensor 39, thereby guiding maintenance personnel to quickly locate the fault point, carry out targeted maintenance and debugging, shorten the equipment troubleshooting time, and improve the availability of the equipment.

[0088] Reference Figure 8 According to the banknote processing device 1 provided by the present invention, the channel connection unit 31 further includes a plurality of displacement sensors 40, which are spaced apart on the channel support 32 along the length direction of the channel support 32; the displacement sensors 40 are used to detect the transmission position of the banknote in the channel inside the channel connection unit 31, so as to determine whether the banknote is being transmitted normally or whether there is a banknote jam.

[0089] Understandably, banknotes come in different sizes and specifications, such as varying lengths for different denominations. Multiple displacement sensors 40 spaced apart can cover the transmission range of banknotes of different lengths, ensuring accurate detection by at least one or more sensors, regardless of whether the banknote is a short, small-denomination note or a long, large-denomination note. This ensures effective position monitoring of banknotes of various sizes, improving the device's adaptability to different banknote specifications.

[0090] Displacement sensor 40 determines whether banknotes are being transmitted normally or if a jam has occurred. When banknotes are being transmitted normally, they pass through each displacement sensor 40 sequentially at a predetermined speed and direction. The displacement sensors 40 detect changes in the banknote's position at regular time intervals. If a banknote jams or becomes stuck at a certain position, the displacement sensors 40 after that position will not be able to detect the arrival of the banknote within the normal timeframe. By analyzing the detection signals from the displacement sensors 40, the equipment can quickly determine the location of the jam. Once the jam location is determined, the equipment can immediately take appropriate measures, such as stopping banknote transmission or issuing an alarm to prompt the operator to clear the jam. Operators can quickly locate the fault point based on the jam location information provided by the equipment and perform targeted troubleshooting without needing to conduct a comprehensive inspection of the entire channel. This significantly shortens troubleshooting time, improves equipment maintenance efficiency, reduces downtime due to malfunctions, and ultimately improves the overall operating efficiency of the equipment.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
