Description

Technical Field

[0001] This invention relates to the field of media transmission technology for financial equipment, and in particular to a transfer trolley and method for transferring and shifting multiple media. Background Technology

[0002] With the increasing automation of financial services, financial self-service equipment (such as ATMs and self-service terminals) has integrated multiple functions, including bill issuance, card reading and issuance, U-key retrieval, and passbook printing. However, due to the modular design logic of the equipment, the various business units of current mainstream financial equipment (such as bill module, card issuance module, U-key storage module, and passbook module) are usually set up independently, and the corresponding media outlets (such as bill slot, card slot, U-key slot, and passbook slot) are distributed.

[0003] In practical use, when customers handle multi-media transactions (such as simultaneously receiving a bank card and a U-key), they need to locate the corresponding media port at different locations on the device and complete the retrieval and placement operations. Due to the dispersed media ports and lack of unified guidance, customers are prone to timeouts due to unfamiliarity with the operation (such as accidental touches or omissions) or excessively long search paths, which in turn triggers the device's timeout protection mechanism, leading to service interruptions or media jamming.

[0004] To address the issue of multi-media distributed transmission, existing technologies often employ robotic arm solutions: using a multi-degree-of-freedom robotic arm to grasp different media and move them between modules within the equipment. However, the robotic arm grasping method has the following drawbacks:

[0005] 1. The robotic arm's motion path planning is complex, and a single multi-media transfer requires multiple positioning and gripping / releasing actions, resulting in low efficiency;

[0006] 2. The robotic arm has a precise structure (including servo motors, sensors, and other components), resulting in high hardware costs and significant maintenance challenges.

[0007] 3. The robotic arm has limited adaptability to media shapes (such as irregularly shaped U-keys and thin tickets), and the media is easily damaged due to improper clamping force.

[0008] Therefore, existing financial self-service equipment urgently needs a transfer cart and method for transferring multiple media, which can simplify the customer's operation path and achieve efficient and low-cost unified transmission of multiple types of media, so as to improve equipment reliability and user experience. Summary of the Invention

[0009] The purpose of this invention is to provide a transfer trolley and method for transferring multiple media, aiming to solve the technical problems of low efficiency, high cost and easy operation failure in the multi-media decentralized transmission of financial self-service equipment.

[0010] To achieve the above objectives, in a first aspect, the present invention provides a transfer trolley for transferring and shifting multiple media, comprising:

[0011] The lower and upper transmission components of the trolley are matched and connected by a height-adjustable mechanism and a guide mechanism, so that the medium transmission channel formed between them can adapt to media of different thicknesses.

[0012] The bottom assembly of the trolley includes a base and a horizontal moving mechanism disposed on the base. The trolley lower transmission assembly is disposed at the moving end of the horizontal moving mechanism. The base is provided with an interface for connecting to the mobile execution end of the financial self-service equipment.

[0013] As a further improvement to the above solution, the trolley lower transmission assembly includes a lower frame with a bottom opening, several sets of active conveying wheel assemblies disposed within the lower frame, and a first drive device.

[0014] Each of the active conveying wheel assemblies is arranged parallel to each other within the lower frame; the first driving device is located on one side of the lower frame and is driven connected to one end of any of the active conveying wheel assemblies; the other end of each active conveying wheel assembly is driven connected through a first synchronous transmission structure; and the wheelbase A between each active conveying wheel assembly is less than the minimum medium length minus a preset value a (preferably a is 10mm).

[0015] Correspondingly, the trolley-mounted transmission assembly includes an upper frame and several sets of driven conveyor wheel assemblies disposed within the upper frame. Each of the driven conveyor wheel assemblies is arranged parallel to each other at intervals within the upper frame and is configured to correspond one-to-one with the active conveyor wheel assembly to realize the movement and transmission of the medium.

[0016] As a further improvement to the above solution, the active conveying wheel assembly includes an active transmission shaft and a plurality of active transmission wheels spaced apart on the active transmission shaft;

[0017] Correspondingly, each group of driven conveyor wheel assemblies is rotatably mounted within the upper frame, and includes a driven transmission shaft and a driven transmission wheel disposed on the driven transmission shaft. Each driven transmission wheel is vertically aligned with the corresponding active transmission wheel to collaboratively provide transmission power for the medium.

[0018] As a further improvement to the above solution, the first driving device includes a first driving motor, a first driving gear driven by the first driving motor, and a first driven gear disposed on one end of the driving transmission shaft, wherein the first driving gear meshes with the first driven gear for transmission.

[0019] Preferably, the first driving gear meshes with the first driven gear through a first intermediate gear.

[0020] As a further improvement to the above solution, the height-adjustable mechanism includes:

[0021] The second drive unit is located on the other side within the lower frame;

[0022] The active drive shaft is connected to the second drive device.

[0023] The driven shaft is arranged parallel to the active drive shaft at a distance, and one end of the driven shaft is connected to the active drive shaft through a second synchronous transmission structure.

[0024] The lifting cams are respectively located at both ends of the driving shaft and the driven shaft;

[0025] The lifting rollers are respectively set on the outside of the upper frame and matched one-to-one with the lifting cams, so that the height of the medium transmission channel is changed by the lifting cams moving the lifting rollers.

[0026] As a further improvement to the above solution, the second drive device includes a second drive motor, a worm gear drivenly connected to the second drive motor, and a turbine gear meshing with the worm gear for transmission.

[0027] The turbine is mounted on the active drive shaft, and the other ends of the active drive shaft and the driven drive shaft are connected by a synchronous belt drive.

[0028] As a further improvement to the above solution, the guiding mechanism includes guide posts disposed on both sides of the lower frame and guide holes disposed on both sides of the upper frame. The guide posts pass through the guide holes, so that the upper transmission component of the trolley can be slidably disposed above the lower transmission component of the trolley.

[0029] As a further improvement to the above solution, the transmission component on the vehicle also includes a medium correction component for correcting the deviation of the medium.

[0030] As a further improvement to the above solution, the media correction component includes:

[0031] The third drive unit is located within the upper frame;

[0032] The camshaft of the stopper is driven and connected to the third drive device;

[0033] The pawl cams are respectively disposed at both ends of the pawl cam shaft;

[0034] The pawl is vertically extendable and retractable at the bottom of the upper frame and located directly below the pawl cam. The pawl includes a pawl body and a plurality of pawl teeth disposed on the pawl body. The pawl teeth pass through the bottom of the upper frame and are operably in contact with the top surface of the lower frame.

[0035] As a further improvement to the above solution, the third driving device includes a third driving motor, a third driving gear driven by the third driving motor, and a third driven gear disposed at one end of the camshaft of the pawl, wherein the third driving gear and the third driven gear mesh and transmit power.

[0036] As a further improvement to the above solution, the media correction component also includes an alignment fiber, which is disposed on the upper frame and used to detect the correction status of the media.

[0037] Furthermore, the alignment fiber is communicatively connected to the third driving device to drive the pawl cam to rotate according to the correction of the medium, thereby releasing the contact with the pawl.

[0038] As a further improvement to the above solution, the transmission component on the trolley also includes a lift position detection sensor and a medium height detection component;

[0039] The lifting position detection sensor is installed inside the lower frame and is used to detect the rotational position of the lifting cam.

[0040] The medium height detection component is installed inside the upper frame to detect the actual height of the medium and is communicatively connected to the second drive device to control the lifting height of the lifting cam based on the detected actual height of the medium.

[0041] As a further improvement to the above solution, the medium height detection assembly includes a height sensor, a sensor bracket, a cantilever shaft rotatably mounted on the sensor bracket, and a crank arm mounted on the cantilever shaft via an elastic element.

[0042] The inflection point of the crank arm is used to contact the medium, and the height sensor is mounted on the sensor bracket and located adjacent to the crank arm;

[0043] Preferably, the elastic element is a torsion spring, used to provide a restoring force for the crank arm.

[0044] As a further improvement to the above solution, the medium transmission channel is also provided with a medium entry sensor, a width detection sensor, and a medium presence sensor group.

[0045] The medium inlet sensor is located at the medium inlet and is used to detect whether a medium is entering.

[0046] The width sensor is set at a preset width position and is used to determine whether it is a specified medium type based on the width information;

[0047] The medium presence sensor group includes at least two medium presence sensors, which are used to determine the medium type by combining the various medium presence sensors.

[0048] As a further improvement to the above solution, the horizontal movement mechanism includes:

[0049] The movable frame is slidably mounted on the upper surface of the base via a linear guide rail assembly;

[0050] A horizontal drive motor is mounted on the base via a vertical motor mounting plate;

[0051] A horizontal drive gear is connected to the horizontal drive motor for driving;

[0052] A horizontal rack is provided on the upper surface of the movable frame;

[0053] The horizontal drive gear passes through the movable frame and meshes with the horizontal rack to drive the movable frame to move horizontally. The movable frame forms the moving end of the horizontal moving mechanism.

[0054] Secondly, the present invention also provides an automatic compatibility method for a transfer trolley for transferring multiple media, as provided in the first aspect, the steps of which include:

[0055] By rotating the lifting cam forward to the highest position, the medium enters the medium transmission channel. Then, the lifting cam is rotated in the reverse direction to reduce the channel height until the medium height detection component is triggered, thus stopping the descent and matching the height of the medium transmission channel with the current medium thickness.

[0056] The oblique medium end is blocked and guided to align by the stop teeth at the end of the stop claw of the medium correction component. After the fiber is aligned and detected to be aligned, the stop claw is released.

[0057] The system detects the size characteristics of the medium using a width sensor and a medium presence sensor group. When the detection result does not match the preset medium type, it provides feedback on misplacement and returns the medium.

[0058] Because the present invention adopts the above technical solutions, the beneficial effects of this application are as follows:

[0059] 1. This invention provides a transfer trolley for transferring various media. First, the transfer trolley provided by this invention can simplify the customer's operation path. Specifically, the height of the media transfer channel formed by the upper and lower transfer components is dynamically adjusted by the height-adjustable mechanism, which automatically adapts to media of different thicknesses (such as U-keys, tickets, etc.). This eliminates the need for customers to search for scattered media ports. They only need to complete the media picking and placing at a unified channel location, reducing operation steps and waiting time, and lowering the timeout failure rate caused by unfamiliarity with operation.

[0060] Secondly, the conveyor provided by this invention can achieve efficient and unified transmission of multiple types of media. Specifically, the upper and lower transmission components work together with the guide mechanism and the height-adjustable mechanism to form a stable single media transmission channel. With the precise positioning of the horizontal moving mechanism, it can be compatible with the continuous transfer of multiple media such as tickets, cards, U-keys, and passbooks, avoiding the inefficiency of traditional robotic arms that grasp media separately and improving the efficiency of single task processing.

[0061] Meanwhile, mechanical transmission structures (such as height-adjustable cams and synchronous pulley sets) are used to replace complex robotic arm solutions, reducing the use of expensive and precision components such as servo motors and sensors, thus lowering hardware costs; and modularly designed transmission components and adjustable mechanisms are easy to disassemble and maintain, reducing the complexity of troubleshooting and parts replacement later.

[0062] In addition, the conveyor provided by this invention can improve equipment reliability and user experience. Specifically, by adaptively adjusting to the thickness of the medium and using a stable transmission channel, it reduces failures such as medium jamming and transmission offset; the unified medium inlet and simplified operation logic reduce the difficulty of use for customers; and combined with high transmission efficiency, it improves the overall service reliability and user satisfaction of financial self-service equipment.

[0063] 2. This invention provides an automatic compatibility method for a transfer trolley used for transferring multiple media. In the first aspect, it can achieve adaptive compatibility of multiple media heights. Specifically, by raising the cam to rotate forward to the highest position to introduce the media, and then rotating it in the reverse direction to reduce the height of the media transmission channel, the cam is automatically adjusted to match the actual thickness of the current media (such as UKEYs of different thicknesses) to trigger a stop. This solves the problem of poor media transmission caused by the need for manual adjustment or fixed height in traditional equipment, and improves the compatibility and transmission reliability of media of multiple thicknesses (such as 15-20mm UKEYs).

[0064] Secondly, it can effectively correct skewed media and ensure transmission alignment. Specifically, the skewed media end is physically blocked by the blocking teeth at the end of the media correction component. After the media end is guided to be aligned, the alignment is confirmed by the alignment fiber and the blocking teeth are released, ensuring the correct position of the media in the transmission channel. This avoids transmission failures or jams caused by media skew and improves the accuracy and stability of media transmission.

[0065] Thirdly, it can accurately identify and intercept incorrectly placed media. Specifically, the width sensor detects the width characteristics of the media, and the media presence sensor group detects the combination characteristics of the media. When the size of the media does not match the preset type (such as passbook, bank card, or bill), the system promptly provides feedback on the misplacement and returns the media. This solves the problem of customers potentially misplacing media in single-interface recycling services, reduces the risk of equipment failure due to misplaced media, and improves the accuracy and security of self-service equipment media recycling.

[0096] Example 1

[0097] See Figures 1-14 This invention relates to the field of financial self-service equipment technology, specifically to a transfer trolley for transferring multiple media (such as bills, bank cards, U-keys, passbooks, etc.), aiming to address the problems of complex operation paths, low transmission efficiency, and high costs caused by the dispersed transmission of multiple media in existing financial self-service equipment.

[0098] The present invention provides a transfer trolley for transferring various media, comprising a lower transfer assembly 1 and an upper transfer assembly 2 arranged vertically and matched, connected by a height-adjustable mechanism 3 and a guiding mechanism 4, so that the media transfer channel 5 formed between them can adapt to media 0 of different thicknesses; it also includes a trolley bottom assembly 6, which includes a base 61 and a horizontal moving mechanism 62 disposed on the base 61. The specific structure is shown below:

[0099] The trolley lower transmission assembly 1 is installed on the moving end of the horizontal moving mechanism 62. It includes a lower frame 11 with a bottom opening, a plurality of active conveying wheel assemblies 12 disposed within the lower frame 11, and a first driving device 13. Each of the active conveying wheel assemblies 12 is arranged parallel to each other at intervals within the lower frame 11. The first driving device 13 is disposed on one side of the lower frame 11 and is drivenly connected to one end of any of the active conveying wheel assemblies 12. The other end of each active conveying wheel assembly 12 is drivenly connected through a first synchronous transmission structure 14 to provide power for the forward transmission of medium O.

[0100] The wheelbase A between each active conveyor wheel assembly 12 must satisfy: A < minimum medium length - preset value a (preferably a is 10mm).

[0101] The minimum medium length 0 refers to the shortest length among the various types of media 0 that the equipment needs to process (for example, the length of a bank card is 85.6 mm, which can be used as a typical minimum value); the preset value a (such as 10 mm) is an engineering experience value used to ensure that even the shortest medium 0 has at least one active transmission wheel 122 in contact with it at any position.

[0102] Assuming the minimum length of medium 0 is 85.6 mm, and a is 10 mm, then the distance A between adjacent active transmission wheels 122 must be less than 75.6 mm (85.6-10). With this setting, regardless of where medium 0 (such as a short bank card or a long bill) is placed in the transmission channel, at least a portion of it will cover at least one active transmission wheel 122, thus ensuring that there is always an effective frictional contact area between the active transmission wheel 122 and medium 0, avoiding "transmission blind spots" caused by excessive wheel spacing.

[0103] The trolley-mounted transmission assembly 2 includes an upper frame 21 and several sets of driven conveyor wheel assemblies 22 disposed within the upper frame 21. Each driven conveyor wheel assembly 22 is spaced apart and parallel to the others within the upper frame 21, corresponding one-to-one with the driving conveyor wheel assembly 12 to achieve the movement and transmission of the medium 0. The driven conveyor wheel assemblies 22 are rotatably mounted on the upper frame 21, have no independent drive, and achieve synchronous rotation through contact friction with the driving conveyor wheel assembly 12.

[0104] The medium transmission channel 5 is formed by the gap between the active conveying wheel assembly 12 and the driven conveying wheel assembly 22 of the upper and lower transmission components. It is used to accommodate the medium 0 to be transferred (such as UKEY, tickets, etc.) and to stabilize the transmission of the medium 0 through the friction of the upper and lower wheel assemblies.

[0105] The height-adjustable mechanism 3 connects the lower transmission assembly 1 and the upper transmission assembly 2 of the trolley. Specifically, it includes a second drive device 31, a drive shaft 32, a driven shaft 33, a second synchronous transmission structure 34 (such as a synchronous belt), a lifting cam 35, and a lifting roller 36. The second drive device 31 is located on one side of the lower frame 11 and drives the drive shaft 32 to rotate. The drive shaft 32 and the driven shaft 33 are arranged parallel to each other and rotate synchronously through the second synchronous transmission structure 34. The lifting cam 35 is installed at both ends of the drive shaft 32 and the driven shaft 33, respectively, to lift the upper frame 21. The lifting roller 36 is correspondingly located outside the upper frame 21 and engages with the lifting cam 35. By driving the lifting cam 35 to rotate through the second drive device 31, the upper frame 21 can be moved up and down, thereby adjusting the distance between the upper and lower transmission assemblies and adapting the height of the media transmission channel 5 to media of different thicknesses (such as 15-20mm U-keys or thinner tickets). When it is necessary to transfer media 0 of different thicknesses, the second drive device 31 drives the lifting cam 35 to rotate, thereby lifting the upper frame 21 by lifting the lifting cam 35, increasing the distance between the upper and lower transmission components to place the media 0; after the media 0 is placed, the lifting cam 35 rotates in the opposite direction to reduce the distance until the upper and lower conveying wheel components clamp the media 0, forming a stable transmission channel adapted to the current thickness of the media 0.

[0106] The guiding mechanism 4 includes guide posts 41 on both sides of the lower frame 11 and guide holes 42 on both sides of the upper frame 21. The guide posts 41 pass through the guide holes 42, so that the upper transmission component 2 of the trolley can be slidably mounted above the lower transmission component 1 of the trolley. The guiding mechanism 4 ensures that the upper and lower transmission components move smoothly during height adjustment, avoiding deviation in medium transmission caused by offset.

[0107] The base 61 serves as the supporting foundation for the trolley, and its bottom is provided with an interface (such as a buckle, slot or bolt hole) for connecting to the mobile execution end within the financial self-service equipment, thereby enabling the trolley to be fixed and guided within the equipment.

[0108] The horizontal moving mechanism 62 includes a moving frame 621 (fixedly connected to the lower frame 11), a vertical motor mounting plate 624, a horizontal drive motor 623, a horizontal drive gear 625, and a horizontal rack 626. The moving frame 621 is slidably mounted on the upper surface of the base 61 via a linear guide rail assembly 622. The horizontal drive motor 623 is fixed to the base 61 via the vertical motor mounting plate 624, and its output shaft is connected to the horizontal drive gear 625. The horizontal rack 626 is fixed to the upper surface of the moving frame 621 and meshes with the horizontal drive gear 625 for transmission. The moving frame 621 constitutes the moving end of the horizontal moving mechanism 62. Specifically, the bottom of the lower frame 11 is fixedly connected to the moving frame 621 via bolts. The horizontal drive motor 623 drives the horizontal drive gear 625 to rotate, causing the horizontal rack 626 and the moving frame 621 to move horizontally along the linear guide rail, thereby aligning the media transmission channel 5 with the target module (such as the outlet of the UKEY issuing module or the inlet of the recycling module) within the financial self-service equipment, ensuring precise docking of the media 0.

[0109] The present invention simplifies the customer's operation path through the conveying trolley provided by the present invention. Specifically, the height of the medium transmission channel 5 formed by the upper and lower transmission components is dynamically adjusted by the height adjustable mechanism 3, which automatically adapts to media 0 of different thicknesses (such as UKEY, tickets, etc.), so that customers do not need to find scattered media ports, but only need to complete the picking and placing of media 0 at a unified channel position, reducing operation steps and waiting time, and reducing the timeout failure rate caused by unfamiliarity with operation.

[0110] Secondly, the conveyor provided by this invention can achieve efficient and unified transmission of multiple types of media. Specifically, the upper and lower transmission components work together with the guide mechanism 4 and the height-adjustable mechanism 3 to form a stable single media transmission channel 5. With the precise positioning of the horizontal moving mechanism 62, it can be compatible with the continuous transfer of multiple media such as tickets, cards, U-keys, and passbooks, avoiding the inefficiency of traditional robotic arms that separate media for each type of grasping and improving the efficiency of single task processing.

[0111] Meanwhile, mechanical transmission structures (such as height-adjustable cams and synchronous pulley sets) are used to replace complex robotic arm solutions, reducing the use of expensive and precision components such as servo motors and sensors, thus lowering hardware costs; and modularly designed transmission components and adjustable mechanisms are easy to disassemble and maintain, reducing the complexity of troubleshooting and parts replacement later.

[0112] In addition, the conveying trolley provided by this invention can also improve equipment reliability and user experience. Specifically, by adapting to the thickness of the medium and providing a stable transmission channel, it reduces failures such as medium jamming and transmission offset; the unified medium entry and simplified operation logic reduce the difficulty of use for customers; and combined with high transmission efficiency, it improves the overall service reliability and user satisfaction of financial self-service equipment.

[0113] In a preferred embodiment, in the multi-media transfer scenario of financial self-service equipment, the lengths of media 0 (such as tickets, bank cards, U-keys, etc.) vary significantly (for example, the length of a ticket can reach 225mm, while the length of a bank card is only about 85.6mm). If the spacing between adjacent active transmission wheels 122 on the active conveying wheel assembly 12 is too large, it may result in short media 0 (such as bank cards) not being covered by any active transmission wheel 122, leading to the problem of no contact or insufficient contact between the transmission wheels and media 0, affecting the stability of the transmission power transmission, and even causing media 0 to deviate or get stuck during transmission.

[0114] To this end, the present invention has made targeted improvements to the wheel arrangement density of the active conveying wheel assembly 12. By controlling the spacing between adjacent active conveying wheels 122, it ensures that media of any length can effectively contact at least one active conveying wheel 122. At the same time, in conjunction with the alignment design of the driven conveying wheel assembly 22, stable collaborative transmission of multiple media is achieved.

[0115] Specifically, the active conveyor wheel assembly 12 is installed within the lower frame 11, and includes:

[0116] The active transmission shaft 121, as the mounting base of the active wheel, is spatially perpendicular to the transmission direction of medium 0, and its two ends are fixed to the two sides of the lower frame 11 by bearings.

[0117] Several active transmission wheels 122 are arranged parallel to each other on the active transmission shaft 121 at intervals. Each active transmission wheel 122 can rotate around the active transmission shaft 121 to directly contact the medium 0 and provide forward frictional driving force.

[0118] The first drive device 13 drives the active transmission shaft 121 to rotate, thereby causing all the active transmission wheels 122 to rotate synchronously.

[0119] The driven conveyor wheel assembly 22 is installed within the upper frame 21 and includes:

[0120] Driven transmission shaft 221 is set parallel to active transmission shaft 121, and its two ends are rotatably mounted on upper frame 21 through bushings to support driven transmission wheel 222;

[0121] The driven transmission wheel 222 is mounted on the driven transmission shaft 221. Each driven transmission wheel 222 is vertically aligned with the corresponding active transmission wheel 122, that is, the vertical projection along the transmission direction of medium 0 completely overlaps, ensuring that medium 0 is evenly clamped between the upper and lower wheel sets.

[0122] A wire spring 223 is mounted on the upper frame 21 and contacts the driven transmission shaft 221 while providing pressure to the driven transmission wheel 222.

[0123] When the active transmission wheel 122 rotates and drives the medium 0 forward, the medium 0 comes into contact with the driven transmission wheel 222 and causes it to rotate passively. The driven transmission wheel 222 and the active transmission wheel 122 clamp each other from above and below, providing bidirectional frictional driving force for the medium 0 on the one hand, and restricting the lateral displacement of the medium 0 through the squeezing force between the wheel sets on the other hand, ensuring that the medium 0 moves stably along the center line of the transmission channel. This is especially suitable for thin or easily deformable media 0, such as thin tickets or soft cards.

[0124] This invention solves the problem of unstable transmission caused by insufficient wheel coverage in multi-media transfer by the dense arrangement (parametric control of spacing) of the active transmission wheel 122 and the alignment and coordination of the driven transmission wheel 222. While ensuring transmission efficiency, it improves the equipment's compatibility with different media lengths, meeting the design requirements of financial self-service equipment for high reliability and low cost.

[0125] In a preferred embodiment, the core function of the first driving device 13 is to transmit the output power of the first driving motor 131 to the active transmission shaft 121, driving the active transmission wheel 122 to rotate, thereby driving the medium 0 forward. It includes:

[0126] The first drive motor 131 is fixedly installed on one side of the lower frame 11, and its output shaft passes through one side plate of the lower frame 11. It serves as the power source for the entire active conveyor wheel assembly 12 and provides constant or adjustable rotational torque.

[0127] The first drive gear 132 is driven and connected to the output shaft of the first drive motor 131, and rotates synchronously with the motor output shaft.

[0128] The first driven gear 133 is fixedly installed at one end of the drive transmission shaft 121 and directly meshes with the first drive gear 132 for transmission.

[0129] In some preferred embodiments, to optimize the transmission path (e.g., adjust the transmission ratio, adapt to spatial layout, or reduce gear wear), the present invention further preferably uses indirect transmission via a first transition gear 134. The first transition gear 134 is also provided on one side plate of the lower frame 11, and the first driving gear 132 meshes with the first driven gear 133 through the first transition gear 134. The introduction of the transition gear can adjust the transmission ratio between the driving gear and the driven gear (e.g., increase or decrease the rotational speed), while changing the relative position of the gear meshing to adapt to the limited installation space within the lower frame 11.

[0130] Through the meshing transmission of the first driving gear 132 and the first driven gear 133 (or via the first transition gear 134), the rotational power of the first drive motor 131 is directly converted into the synchronous rotation of the active transmission shaft 121, ensuring that all active transmission wheels 122 rotate at the same speed, providing uniform driving force to the medium 0, and avoiding transmission offset or jamming caused by uneven power distribution.

[0131] In a preferred embodiment, the height-adjustable mechanism 3 is installed between the lower frame 11 and the upper frame 21 of the conveyor trolley, and includes:

[0132] The second drive unit 31 is located on the other side inside the lower frame 11 and is arranged opposite to the first drive unit 13 of the active conveying wheel assembly 12, serving as a power source for adjusting the height of the medium transmission channel 5.

[0133] The active drive shaft 32 is rotatably mounted on the lower frame 11 and is driven by the second drive device 31.

[0134] The driven drive shaft 33 is arranged parallel to the active drive shaft 32 at intervals and is symmetrically distributed along the width direction of the lower frame 11. One end of the driven drive shaft 33 is connected to the active drive shaft 32 through the second synchronous transmission structure 34 (such as a synchronous belt or synchronous chain) to ensure that the active drive shaft 32 and the driven drive shaft 33 rotate synchronously.

[0135] There are four lifting cams 35, which are fixedly installed at both ends of the active drive shaft 32 and the driven drive shaft 33, one at each end of the active drive shaft 32 and one at each end of the driven drive shaft 33, and are used to lift the upper frame 21 upward.

[0136] The lifting rollers 36 are respectively set on the outside of the upper frame 21 (in this embodiment, they are usually installed at the four corners on both sides of the upper frame 21, with connecting ears extending outward from the two opposite sides of the upper frame 21, and the connecting ears are also provided with the guide holes 42, and the lifting rollers 36 are provided on the outer edge of the connecting ears). Each lifting roller 36 is in contact with a lifting cam 35. When the lifting cam 35 rotates, the upper frame 21 is pushed up and down by the rolling contact of the lifting rollers 36.

[0137] In the initial state, when the second drive device 31 is not started, the lifting cam 35 is at the initial rotation angle (e.g., the lowest point), and the upper frame 21 (and the upper transmission component) maintains a minimum distance from the lower frame 11 (and the lower transmission component) under the action of gravity (to adapt to thinner media 0, such as tickets).

[0138] When a thicker medium 0 (such as a UKEY) needs to be transferred, the second drive device 31 starts and drives the active drive shaft 32 to rotate, which in turn drives the driven drive shaft 33 to rotate synchronously through the second synchronous transmission structure 34. The lifting cams 35 at both ends of the active drive shaft 32 and the driven drive shaft 33 rotate accordingly, gradually lifting the lifting rollers 36 at the bottom of the upper frame 21. The upper frame 21 drives the upper transmission component to move upward, so that the distance between the upper and lower transmission components (i.e., the height of the medium transmission channel 5) gradually increases until it matches the thickness of the current medium 0 (for example, the adjustment stops after the sensor detects that the medium 0 is stably clamped).

[0139] After the medium 0 is transferred, the second drive device 31 rotates in the opposite direction, driving the lifting cam 35 to rotate, and the lifting roller 36 moves down accordingly. The upper frame 21 drives the upper transmission component to descend, and the height of the medium transmission channel 5 returns to the initial state or adapts to the thickness of the next medium 0.

[0140] Driven by the second drive device 31, the cam-roller height-adjustable mechanism 3 lifts the lifting roller 36 gradually during rotation by using a contour curve (such as an involute or arc segment) designed by the lifting cam 35. This achieves precise and stable adjustment of the height of the media transmission channel 5. While being compatible with media of various thicknesses, it reduces hardware costs and maintenance complexity, solves the problems of high cost and low reliability of traditional robotic arm solutions, and meets the technical requirements of financial self-service equipment for efficient and low-cost media transmission.

[0141] In a preferred embodiment, the second drive device 31 includes a second drive motor 311, a worm gear 312 drivenly connected to the second drive motor 311, and a turbine 313 meshing with the worm gear 312 for transmission.

[0142] The turbine 313 is mounted on the active drive shaft 32, and the other ends of the active drive shaft 32 and the driven drive shaft 33 are connected by a synchronous belt drive.

[0143] The second drive unit 31 is the power core of the height-adjustable mechanism 3, and specifically includes:

[0144] The second drive motor 311 is fixedly installed on the other side of the lower frame 11 (usually near one end of the active drive shaft 32) to provide rotational power for the entire height adjustment process. It is preferably a small servo motor or a stepper motor.

[0145] The worm gear 312 is driven and connected to the output shaft of the second drive motor 311, and rotates synchronously with the motor output shaft.

[0146] The turbine 313 meshes with the worm gear 312 for transmission and is fixedly mounted on the drive shaft 32. It rotates synchronously with the worm gear 312, thereby driving the drive shaft 32 to rotate.

[0147] When the second drive motor 311 starts, its output shaft drives the worm 312 to rotate. The worm 312 meshes with the turbine 313 through its helical teeth, transmitting rotational power to the turbine 313. Since the turbine 313 is fixed to the drive shaft 32, it drives the drive shaft 32 to rotate synchronously. Because the worm 312-turbine 313 transmission has a self-locking characteristic (i.e., the turbine 313 cannot drive the worm 312 in reverse), it can prevent the height of the medium transmission channel 5 from unexpectedly dropping due to external force after adjustment, thus improving the stability after adjustment.

[0148] The other ends of the drive shaft 32 and the driven shaft 33 are connected by a synchronous belt drive (e.g., a flat belt, V-belt, or synchronous toothed belt). A corresponding synchronous pulley (with the same specifications as the synchronous pulley on the drive shaft 32) is fixed on the driven shaft 33. When the drive shaft 32 rotates, it drives the driven shaft 33 to rotate synchronously through the synchronous belt, ensuring that the lifting cams 35 at both ends of the drive shaft 32 and the driven shaft 33 maintain the same rotation angle and speed, thus avoiding the upper frame 21 from tilting or jamming due to asynchronous rotation of the cams at both ends.

[0149] This invention achieves precise, stable, and balanced adjustment of the height of the medium transmission channel 5 through a worm gear 312-turbine 313 reduction transmission and synchronous belt structure. While improving the compatibility of mediums of various thicknesses, it also enhances the reliability of the adjustment process and the service life of the equipment. It solves the problems of low adjustment accuracy, poor synchronization, or high cost in traditional drive schemes, and meets the technical requirements of financial self-service equipment for efficient and low-cost medium transfer.

[0150] In a preferred embodiment, during the multi-media transfer process of financial self-service equipment, medium 0 (such as tickets, bank cards, U-keys, etc.) may shift its position due to initial placement misalignment or airflow disturbance, i.e., "misalignment". If medium 0 enters the transmission channel misaligned, it may cause friction and jamming with the inner wall of the channel during subsequent transmission, or even fail to accurately enter the target module (such as the U-key issuing or retrieval module), affecting transmission efficiency and success rate. To address the problem of medium 0 misalignment, this invention proposes a medium deviation correction component 7 integrated into the upper transmission assembly. Through the coordinated action of mechanical grippers 74 and sensors, it automatically corrects the misaligned medium 0, ensuring stable, centered transmission of medium 0.

[0151] Specifically, the media correction component 7 includes:

[0152] The third drive device 71, as the power source for the correction action, is installed inside the upper frame 21;

[0153] The camshaft 72 is driven and connected to the third drive device 71; it is rotatably mounted on the upper frame 21, and cams 73 are fixed at both ends; the contour curve of the cam 73 is designed to push the cam 74 downward when rotating.

[0154] The pawl 74 is vertically extendable and retractable at the bottom of the upper frame 21 (e.g., through a guide sleeve and guide post for vertical guidance), located directly below the pawl cam 73. Each pawl 74 includes a pawl body 741 (fixed to the bottom of the guide post) and several teeth 742 (evenly distributed on the pawl body 741, for example, 2-4 teeth). The teeth 742 pass through the bottom of the upper frame 21 and are operably in contact with the top surface of the lower transmission assembly.

[0155] In the initial state, the third drive device 71 is controlled to rotate in the forward direction. When the pawl cam 73 rotates and pushes the pawl 74 downward, the pawl 74 overcomes the elastic force, extends out of the upper frame 21 and abuts against the top surface of the lower transmission component, forming a blockage to the medium transmission channel 5.

[0156] After medium 0 enters the transmission channel, if no deviation occurs, the teeth 742 of the pawl 74 remain flush with the edge of medium 0. The third drive device 71 is controlled to rotate in the opposite direction, and the protruding part of the pawl cam 73 leaves the pawl 74. Under the action of the elastic member 94, the pawl 74 retracts into the upper frame 21, releasing the obstruction to the medium transmission channel 5, and medium 0 continues to be transmitted normally.

[0157] If medium 0 is deviated, the deflecting tooth 742 on the deviated side will contact the edge of medium 0 to prevent it from deviating further. At the same time, the edge of medium 0 is guided to gradually align with the deflecting tooth 742 with the deflecting tooth 742 as a reference.

[0158] In some preferred embodiments, an alignment fiber 75 is also provided, which is fixed to the upper frame 21 (e.g., installed near the center line of the transmission channel) for real-time detection of the edge position of the medium 0. When the medium 0 is aligned, the optical path detected by the alignment fiber 75 is blocked or evenly blocked; when the medium 0 is skewed, the fiber detects an asymmetric blocking signal at the edge of the medium 0 (e.g., reduced light intensity on one side). The alignment fiber 75 is communicatively connected to the third drive device 71. When it detects that the medium 0 is not aligned, it triggers an alarm or illuminates a designated indicator light. Under the action of the active and driven conveyor wheel assemblies, the skewed medium 0 is guided to gradually align its end with the stop tooth 742, using the stop tooth 742 as a reference. When the alignment fiber 75 detects that the medium 0 is aligned, the third drive device 71 rotates in the opposite direction, the protruding part of the stop cam 73 leaves the stop cam 74, and the stop cam 74 retracts into the upper frame 21 under the action of the elastic member 94, releasing the obstruction to the medium transmission channel 5, and the medium 0 continues to be transmitted normally.

[0159] The blocking teeth 742 of the blocking claw 74 pass through the bottom of the upper frame 21 and contact the top surface of the lower transmission component, forming a physical obstruction and lateral thrust. This force can directly act on the end of the deflected medium 0. Compared with simple airflow or vibration correction methods, the guiding force is more stable and controllable. The blocking claw 74, through its vertically extendable design (combined with the rotation of the blocking claw cam 73), can flexibly switch between "blocking-correction-release" working states according to correction requirements, avoiding continuous obstruction from affecting the normal transmission of medium 0. The alignment fiber 75 detects the position of medium 0 in real time and forms a feedback loop with the third drive device 71, ensuring that the correction action is triggered only when needed, reducing unnecessary mechanical movements and improving system efficiency.

[0160] In a preferred embodiment, the third driving device 71 is the power core of the media correction assembly 7, and is installed inside the upper frame 21, specifically including:

[0161] The third drive motor 711 is fixedly installed on the inner wall of the upper frame 21 (e.g., via a motor bracket) and serves as the power source for the correction action. It is preferably a small DC motor or a stepper motor with its output shaft set in a preset direction.

[0162] The third drive gear 712 is driven and connected to the output shaft of the third drive motor 711, and rotates synchronously with the motor output shaft.

[0163] A pawl camshaft 72 is rotatably mounted on the upper frame 21, with pawl cams 73 fixed at both ends; a third driven gear 713 is fixed at one end of the pawl camshaft 72 (on the same side as the third driving gear 712);

[0164] The third driven gear 713 meshes with the third driving gear 712, and its number of teeth and module are matched with those of the third driving gear 712. It is used to transmit the rotational power of the third driving gear 712 to the camshaft 72.

[0165] The gear meshing transmission scheme driven by the third drive motor 711 achieves precise and stable drive of the camshaft 72, which simplifies the transmission structure and improves the reliability and efficiency of the medium zero correction action.

[0166] In a preferred embodiment, during the height adaptive adjustment of the conveyor trolley, it is necessary to precisely control the rotational position of the lifting cam 35 (to ensure that the height of the medium transmission channel 5 matches the actual thickness of the medium 0) and to obtain the actual height of the medium 0 in real time. To address this requirement, this invention proposes an intelligent adjustment scheme integrating a lifting position detection sensor 8 and a medium height detection component 9. By using the sensors to provide real-time feedback of the status information of the medium 0 and the cam, precise adaptive control of the height of the medium transmission channel 5 can be achieved.

[0167] The lifting position detection sensor 8 is fixedly installed inside the lower frame 11 (for example, fixed near the lifting cam 35 by a sensor bracket 92); it is used to detect the rotational position of the lifting cam 35 in real time (e.g., the initial position, maximum lifting position, or intermediate position of the cam). When the second drive device 31 drives the lifting cam 35 to rotate, the sensor senses the rotation angle of the cam through non-contact (e.g., photoelectric sensor) or contact (e.g., micro switch) methods, and feeds back the position signal to the control system (e.g., the trolley controller or the central processing unit of the financial self-service equipment) to ensure that the lifting cam 35 stops at a preset target position, such as the cam angle corresponding to the height matching the actual thickness of the medium 0, to avoid over-lifting or under-lifting.

[0168] The medium height detection component 9 is installed inside the upper frame 21 and includes:

[0169] A height sensor 91 is fixedly mounted on a sensor bracket 92 and is used to detect changes in the position of the crank arm 95 and convert them into a medium 0 height signal.

[0170] The sensor bracket 92 is installed inside the upper frame 21 and serves as the support base for the height sensor 91 and the crank arm 95.

[0171] The cantilever shaft 93 is rotatably mounted on the sensor bracket 92 (e.g., fixed by a bearing or bushing) and serves as the rotation axis of the crank arm 95.

[0172] The crank arm 95 is rotatably mounted on the cantilever shaft 93 via an elastic element 94 (preferably a torsion spring) in the middle. One end of the crank arm 95 is a free end (for touching the medium 0), and the other end is a fixed end (located adjacent to the height sensor 91). The inflection point of the crank arm 95 is close to the free end, so that when the free end is touched by the medium 0, it can rotate around the shaft and drive the fixed end to move.

[0173] The elastic element 94 is sleeved on the cantilever shaft 93. One end is fixed to the sensor bracket 92, and the other end is connected to the fixed end of the crank arm 95, providing a reset elastic force for the crank arm 95. When the medium 0 is removed, the crank arm 95 returns to its initial position under the action of the torsion spring.

[0174] The combination of the lift position detection sensor 8 and the medium height detection component 9 forms a closed-loop control logic of "detection-calculation-adjustment". The lift position detection sensor 8 ensures that the cam stops accurately, and the medium height detection component 9 provides real-time feedback on the height of the medium 0 and dynamically adjusts the lift height, so that the height of the medium transmission channel 5 is always precisely matched with the current medium 0 (such as UKEY or tickets of different thicknesses).

[0175] As a preferred embodiment, in the multi-media transfer scenario of financial self-service equipment, it is necessary to accurately identify the type of medium 0 entering the transmission channel (such as bills, bank cards, U-keys, passbooks, etc.) to avoid misoperation (such as mistakenly placing a bank card into the passbook recycling slot) or transmission failures caused by incompatible medium 0 types. Traditional solutions may only detect the presence or absence of medium 0 using a single sensor, unable to distinguish specific medium 0 types, or rely on complex mechanical structures to sort medium 0, resulting in low identification accuracy and high cost. To address this need, this invention proposes a composite detection scheme integrating a medium sensor 10, a width sensor 011, and a medium presence sensor 012. By detecting the entry status, width characteristics, and position combination information of medium 0 from multiple dimensions, it achieves accurate identification of the medium 0 type, improving transmission reliability and user experience. Specifically, as shown below:

[0176] The medium inlet sensor 10 is installed at the medium inlet of the medium transmission channel 5 (i.e., the initial position where medium 0 enters the transmission channel, usually near the exit of the corresponding module of the financial self-service equipment); it is used to detect in real time whether medium 0 has entered the transmission channel. When a customer takes out or puts in medium 0 from a device module (such as a UKEY issuing module or a recycling module), medium 0 first reaches the medium inlet; the medium inlet sensor 10 (such as an infrared beam sensor or a reflective photoelectric sensor) emits a signal (such as infrared light) through the transmitting end, and the receiving end detects whether the signal is blocked, thereby determining whether medium 0 has entered the transmission channel. If medium 0 is detected to have entered, the subsequent detection process is triggered (such as activating the width detection sensor 011 and the medium presence sensor 012 group).

[0177] The width sensor 011 is fixed at a preset width position in the medium transmission channel 5, such as... Figure 14 In this process, the width B of the width sensor 011 must be installed at a position that satisfies 120mm < B < 125mm; the width information is used to determine whether the incoming medium 0 is of a specified type. The width sensor 011 (such as a single-sided infrared transmitter-receiver pair) determines the width of the medium 0 by detecting the occlusion state of the medium 0 at a preset width position—if the width of the medium 0 exceeds a preset threshold, it is determined to be a non-specified type (such as a non-bank card); if the width of the medium 0 is within the target range, it is initially determined to be a possible target medium 0 type. The width sensor 011 uses non-contact detection (no mechanical contact) to avoid wear on the surface of the medium 0, and at the same time, it has a fast response speed and can provide real-time feedback of width information.

[0178] The medium presence sensor group 012 includes at least two medium presence sensors 012 (e.g., three or four), spaced apart at the top of the medium transmission channel 5 along the medium 0 transmission direction (the specific positions are designed according to the length characteristics of the medium 0, such as a bank card with a minimum medium 0 length of 85.6mm; the sensor spacing must meet the requirements of subsequent logic judgment). The specific type of the medium 0 is determined by the combined detection signals of each sensor. Each medium presence sensor 012 (e.g., an infrared through-beam sensor or a capacitive proximity sensor) is used to detect the presence of the medium 0 at a specific location (signal changes when the medium 0 obstructs the sensor). By analyzing the obstruction combinations of different sensors (e.g., which sensor is obstructed first, which sensors are obstructed simultaneously), the length and shape characteristics of the medium 0 can be inferred, thereby identifying the type of the medium 0. For example:

[0179] If only one sensor detects medium 0 (corresponding to short-length medium 0, such as a bank card), and the position of that sensor matches the standard length characteristics of a bank card, then it is determined to be a bank card;

[0180] If multiple sensors are blocked consecutively (corresponding to a long-length medium 0, such as a ticket), and the blocking range exceeds the minimum length of the ticket (such as 160mm), then it is determined to be a ticket.

[0181] If the occlusion pattern of the sensor combination matches the characteristics of the passbook (such as occlusion in the middle and transparency at both ends), it is determined to be a passbook.

[0182] This invention achieves accurate identification of medium type 0 and protection against misoperation through the coordinated detection of a group of medium sensor 10, width sensor 011 and medium presence sensor 012. While improving transmission reliability, it ensures non-contact detection and low maintenance costs, and solves the problems of low detection accuracy and inability to distinguish medium type 0 by traditional single sensors. It meets the technical requirements of financial self-service equipment for high accuracy and high compatibility of medium type 0 management.

[0183] In a preferred embodiment, in financial self-service equipment, the transfer cart needs to be precisely positioned at the medium 0 inlet / outlet of different functional modules (such as the UKEY issuance module, recycling module, etc.) to ensure accurate docking and transmission of medium 0 (such as bank cards, UKEYs, tickets, etc.). To address this requirement, this invention proposes a horizontal moving mechanism 62 based on gear-rack meshing transmission. A horizontal drive motor 623 drives the drive gear to rotate, which in turn drives the rack on the moving frame 621 to move linearly, thereby precisely controlling the horizontal position of the transfer cart and ensuring efficient docking of the medium transmission channel 5 with the target module.

[0184] Specifically, the horizontal moving mechanism 62 is mounted on the base 61 of the conveying trolley and is used to drive the lower conveying assembly 1 (and the medium conveying channel 5) of the trolley to move precisely in the horizontal direction. It includes:

[0185] The movable frame 621, serving as the movable end of the horizontal moving mechanism 62, is slidably mounted on the upper surface of the base 61 via the linear guide rail assembly 622. A horizontal rack 626 is fixedly installed on its upper surface, and its bottom is fixedly connected to the slider of the linear guide rail assembly 622.

[0186] The horizontal drive motor 623 is fixed to the base 61 by the vertical motor mounting plate 624 and serves as the power source for the horizontal movement of the moving frame 621. It is preferably a small servo motor or stepper motor with the output shaft set horizontally.

[0187] The horizontal drive gear 625 is driven and connected to the output shaft of the horizontal drive motor 623, and rotates synchronously with the output shaft of the motor; the number of teeth and the module of the gear are designed according to the required transmission ratio and movement speed.

[0188] A horizontal rack 626 is fixedly installed on the upper surface of the movable frame 621 and meshes with the horizontal drive gear 625 for transmission; the length of the rack is matched with the expected travel of the movable frame 621.

[0189] It should be noted that the base 61 serves as the supporting foundation for the conveyor trolley, and its upper surface is equipped with a linear guide rail assembly 622 (for guiding the linear movement of the moving frame 621) and a vertical motor mounting plate 624 (for fixing the horizontal drive motor 623).

[0190] The horizontal moving mechanism 62, driven by gear and rack meshing and guided by linear guide rail, achieves precise and stable horizontal movement of the transfer trolley. While ensuring efficient docking between the media transmission channel 5 and the target module, it reduces hardware costs and maintenance complexity, solves the problems of low accuracy and poor stability of traditional positioning schemes, and meets the technical requirements of financial self-service equipment for high-reliability media transfer.

[0191] Example 2

[0192] This invention also provides an automatic compatibility method for a transfer cart used for transferring multiple media, as provided in Embodiment 1. This method is applied to scenarios involving the transfer of multiple media (such as U-keys, passbooks, tickets, and bank cards) in financial self-service equipment. The transfer cart needs to move between different functional modules, such as the U-key issuance module, passbook issuance module, ticket issuing module, and card issuing module, to achieve the issuance and retrieval of media 0. The height of U-keys varies significantly (15-20mm), and in retrieval scenarios, customers may mistakenly place media 0 (e.g., mistakenly placing a bank card into the passbook retrieval slot). Therefore, an automatic compatibility method is needed to solve the problems of adaptive adjustment of media 0 height and identification of incorrect media 0, ensuring transmission stability and business accuracy.

[0193] Specifically, the steps of the automatic compatibility method provided by this invention include:

[0194] S1, Medium 0 height adaptive adjustment steps to solve the UKEY height compatibility problem;

[0195] Medium 0 introduced into the lifting channel:

[0196] When the conveyor trolley moves to the target module (such as the UKEY dispensing module), it first controls the lifting cam 35 to rotate forward to the highest position (corresponding to a media transmission channel 5 height of 28mm). This height is a preset maximum value to ensure that media 0 of different thicknesses (especially UKEYs with a maximum thickness of 20mm) can smoothly enter the media transmission channel 5. For example, when the UKEY is delivered from the module outlet, the 28mm channel height can prevent the media 0 from colliding with the top of the channel, ensuring that the media 0 enters smoothly.

[0197] Reduce the thickness of the channel matching medium:

[0198] After medium 0 enters the channel, the lifting cam 35 is slowly rotated in the opposite direction, causing the height of the medium transmission channel 5 to gradually decrease (the crank arm 95 decreases synchronously with the channel height). When the crank arm 95 (located inside the channel to contact medium 0) contacts the top of the current medium 0 (such as a UKEY), the crank arm 95 rotates and lifts due to force, triggering the height sensor 91 (such as a microswitch or photoelectric sensor). After the height sensor 91 is triggered, the control system immediately stops the rotation of the lifting cam 35. At this time, the height of the medium transmission channel 5 is automatically adjusted to match the actual thickness of the current medium 0 (such as a 15-20mm UKEY). This step achieves precise height adjustment through mechanical contact feedback, avoiding adaptation errors caused by manual intervention or fixed settings.

[0199] S2, Medium 0 correction step to ensure transmission alignment;

[0200] If medium 0 is deviated after entering the channel, the medium correction component 7 will be activated:

[0201] The pawl 74 guides the alignment, and the end tooth 742 of the pawl 74 of the medium correction component 7 (located in the channel and can extend and retract up and down) blocks the medium 0 in the initial state. When the end of the deflected medium 0 contacts the tooth 742, the tooth 742 guides the end of the medium 0 to gradually align through physical contact.

[0202] When the alignment fiber 75 (mounted on the upper frame 21 to detect the alignment status of medium 0) detects that the end of medium 0 is aligned (e.g., the fiber optic signal shows that the edges of medium 0 are symmetrical), the stop 74 rotates and lifts under the action of the third drive device 71, releasing the obstruction to medium 0, allowing medium 0 to transmit normally. This step, through mechanical and optical collaborative detection, ensures that medium 0 maintains a stable posture during transmission, avoiding jamming or friction damage caused by skewness.

[0203] S3, Error Media 0 Identification and Return Steps to Solve the Problem of Misplacement in Recycling Scenarios;

[0204] In the media 0 recycling business (such as when customers choose to recycle passbooks, bills, or bank cards), in order to prevent customers from accidentally placing media 0 (such as putting a bank card into the passbook recycling slot), the size characteristics of media 0 are detected by a set of width sensor 011 and media presence sensor 012, and compared with the standard size of the preset media 0 type.

[0205] The preset parameters and detection logic are as follows:

[0206] Based on survey data: the common dimensions of bills are 160-225mm in length, 80-120mm in width, and 0.1-0.3mm in thickness; the common dimensions of bank cards are 85.6mm in length, 53.98mm in width, and 0.76mm in thickness; and the common dimensions of passbooks are 150-199mm in length, 125-160mm in width, and 1-2mm in thickness.

[0207] See Figure 14 The installation position of the width sensor 011 satisfies 120mm < B < 125mm, and the sensor spot diameter is less than 5mm; the distance C between each sensor in the medium presence sensor group 012 satisfies C < minimum medium 0 length - 20mm (e.g., if the length of a bank card is 85.6mm, then C < 65.6mm, ensuring that at least one sensor can detect medium 0), which is used to determine the length and shape characteristics of medium 0 through the combined signals of multiple sensors.

[0208] The following is an example of how to handle a specific misplacement scenario:

[0209] D1. Mistakenly placing bank cards / receipts during passbook recycling service;

[0210] D101. When a customer selects the passbook recycling service and inserts a bank card or a receipt, the width sensor 011, unable to detect a medium 0 (bank card width 53.98mm, receipt width 80-120mm) within the passbook width range (125-160mm), triggers a signal to the host computer.

[0211] D102. The host computer determines that the medium 0 type is mismatched based on the sensor signal, reports the misplacement information, and controls the conveyor trolley to return medium 0 to the customer.

[0212] D2. Mistakenly placing passbooks / bank cards in the bill collection business;

[0213] D201. If a customer mistakenly inserts the medium into the passbook, the width sensor 011 detects that the width of the medium is within the passbook width range (125-160mm) and sends a feedback signal to the host computer.

[0214] D202, The host computer reports the misplacement information and controls the return of medium 0;

[0215] D203. If a customer mistakenly inserts a bank card, and only one sensor in sensor group 012 detects medium 0 (the bank card is shorter, triggering only a single sensor), while a bill (which is longer) will usually trigger at least two sensors; the host computer determines that medium 0 is a bank card based on the sensor combination signals (which does not match the bill recycling business), provides feedback on the mistaken insertion, and returns medium 0.

[0216] D204. After the host computer confirms that the medium type 0 is incorrect based on the integrated sensor data, it controls the transfer trolley to return medium 0 to the customer operation interface to avoid equipment failure or business process interruption caused by accidental recycling.

[0217] This invention achieves dynamic adaptation (within a range of 15-20mm) between the height of the medium transmission channel 5 and the actual thickness of the current medium 0 (such as a UKEY) by lifting the cam 35 in the forward direction (introducing medium 0) and lowering it in the reverse direction (matching thickness), combined with the contact trigger feedback of the crank arm 95. This solves the compatibility problem of UKEYs with multiple thicknesses and ensures stable clamping without excessive compression during the transmission of medium 0.

[0218] The media correction component 7 ensures that the ends of the skewed medium 0 are aligned and the obstruction is released after the physical guidance of the claws 74 and the optical detection of the alignment fiber 75. This avoids transmission jamming or damage to the inner wall of the channel caused by the skew of the medium 0, and improves the smoothness and reliability of the medium 0 transmission.

[0219] The width sensor 011 and the medium presence sensor 012 group quickly identify misplaced medium 0 (such as bank cards in passbook recycling business, passbooks or bank cards in bill recycling business) by comparing the size feature detection (width and length combination) with the standard parameters of the preset medium 0 type. The system then provides feedback and returns the misplaced medium through the host computer to prevent equipment malfunctions or a decline in customer experience caused by misplacement.

[0220] The automatic compatibility method of this invention achieves stable transmission and misplacement protection in scenarios involving multiple media (especially multi-thickness UKEYs) through three core steps: highly adaptive adjustment, media zero-correction, and error identification. While improving transmission efficiency and reliability, it reduces equipment costs and maintenance complexity, and solves the key technical problems of multi-media transfer and relocation in financial self-service equipment.

[0221] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
