Description

Technical Field

[0001] This invention relates to the fields of control systems and intelligent book management, and in particular to a multi-channel adaptive book transport control system based on differential speed and friction separation. Background Technology

[0002] Automated book management devices can support users in returning books automatically. Returned books need to be separated first, and then categorized and shelved. Currently, automated book return requires users to manually drop the books one by one at the front of the device, achieving the goal of manual book separation. The manually separated books are then transported along a single conveyor belt along a fixed route. While the conveyor belt provides uninterrupted, assembly-line transport, it can only transport books placed in a fixed direction after manual separation. The conveyor belt cannot automatically start and stop, nor can it flexibly select different delivery directions. It cannot adapt to the transport of randomly scattered books, resulting in a rigid transport method that requires forced delivery by the user, leading to low efficiency and a less than user-friendly experience.

[0003] In summary, existing book return technologies suffer from several technical problems, including inability to adapt to the transportation of books that are randomly scattered and dropped, rigid transportation methods, the need to force users to accept the books, low efficiency, and a less than user-friendly experience. Summary of the Invention

[0004] To address the shortcomings of the existing technologies, this invention provides a multi-channel adaptive book transport control system based on differential speed and friction separation to achieve automatic book unpacking and rapid separation. This system features a small footprint, high speed, low noise, and high efficiency, solving the separation problem that plagues libraries and enabling large-scale production of the equipment. It saves manpower and resources used for book unpacking and separation, thereby improving the efficiency and intelligence of book management.

[0005] This invention provides a multi-channel adaptive book transport control system based on differential and friction separation, comprising: A multi-book delivery and transmission mechanism is installed on the upper side of a rack. The multi-book delivery and transmission mechanism has a delivery and transmission area for multiple books, and the books in the delivery and transmission area are transmitted in a preset transmission direction. The book separation assembly is suspended on the first gantry frame of the machine frame. Driven by the upward drive signal, it slowly rises on the first gantry frame at a preset slow rising speed to separate the stacked books. This allows books of a first preset thickness to continue to be transported in the preset transmission direction through the multi-book delivery and transmission mechanism. A book separation monitoring device is installed on the upper side of the rack and below the book separation assembly. It is used to generate the rising drive signal and send it to the book separation assembly when it detects that a book has been transferred to the lower side of the book separation assembly. Multiple book monitoring and transmission units are located at the book output end of the multi-book delivery and transmission mechanism and their book transmission speed is greater than that of the multi-book delivery and transmission mechanism, forming a book transmission differential. The multiple book monitoring and transmission units are arranged in a row and installed at intervals on the rack to form multiple independent book monitoring and transmission channels with the same transmission direction. When each book monitoring and transmission unit detects that there are books to be transmitted in its own book monitoring and transmission channel, it transmits the books that need to be transmitted. A downward friction wheel assembly is mounted on the frame and located above the plurality of book monitoring and transmission units. When there are books being transmitted on any number of book monitoring and transmission channels, the downward friction wheel assembly applies a first frictional force to the upper surface of the top layer of books being transmitted. The book monitoring and transmission unit responsible for transmitting books on the corresponding book monitoring and transmission channel transports the stacked books and applies a second frictional force to the lower surface of the bottom layer of books. The first frictional force is less than the second frictional force.

[0006] Compared with the prior art, the beneficial effects of this invention are as follows: This invention provides a multi-channel adaptive book transport control system based on differential speed and friction separation. The system includes a multi-book delivery and transport mechanism mounted on the upper side of a frame, each mechanism having a delivery and transport area for multiple books, with the books in the delivery and transport areas transported in a preset transport direction; a book separation assembly suspended on a first gantry on the frame, which slowly rises on the first gantry at a preset slow rising speed according to a rising drive signal to separate stacked books, allowing books of a first preset thickness to continue transported in the preset transport direction via the multi-book delivery and transport mechanism; a book separation monitoring device mounted on the upper side of the frame and located below the book separation assembly, used to generate the rising drive signal and send it to the book separation assembly when a book is detected being transported below it; and multiple book monitoring and transport units located on the multi-book delivery and transport mechanism. The book output end of the conveying mechanism has a book conveying speed greater than that of the multi-book delivery and conveying mechanism, forming a book conveying differential speed. The multiple book monitoring and conveying units are arranged in a row and installed at intervals on the frame, forming multiple independent book monitoring and conveying channels with the same conveying direction. When each book monitoring and conveying unit detects that there is a book to be conveyed in its own book monitoring and conveying channel, it conveys the book to be conveyed. A pressure friction wheel assembly is installed on the frame and located above the multiple book monitoring and conveying units. When there are books being conveyed on any number of book monitoring and conveying channels, the pressure friction wheel assembly applies a first frictional force to the upper surface of the top layer of books stacked in the conveying process. The book monitoring and conveying unit that is responsible for conveying books on the corresponding book monitoring and conveying channel transports the stacked books and applies a second frictional force to the lower surface of the bottom layer of books. The first frictional force is less than the second frictional force. This system can automatically break up and quickly separate books, achieving small footprint, high speed, low noise, and high efficiency. It not only solves the separation problem that plagues libraries but also enables large-scale production of the equipment, saving manpower and resources for book breaking up and separation, and improving the efficiency and intelligence of book management.

Detailed Implementation

[0009] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0010] See Figures 1-7 This invention provides a multi-channel adaptive book transport control system based on differential and friction separation, comprising: A multi-book delivery and transmission mechanism 1 is installed on the upper side of a frame 2. The multi-book delivery and transmission mechanism 1 has a delivery and transmission area 10 for multiple books, and the books in the delivery and transmission area 10 are transmitted in a preset transmission direction. The book separation component 3 is suspended on the first gantry 34 on the frame 2. Driven by the rising drive signal, it slowly rises on the first gantry 34 at a preset slow rising speed to separate the stacked books, so that the books of the first preset thickness continue to be transported in the preset transmission direction through the multi-book delivery and transmission mechanism 1. The book separation monitoring device 4 is installed on the upper side of the frame 2 and located below the book separation assembly 3. It is used to generate the rising drive signal and send it to the book separation assembly 3 when it detects that a book has been transferred to the lower side of the book separation assembly 3. Multiple book monitoring and transmission units 5 are located at the book output end of the multi-book delivery and transmission mechanism 1 and their book transmission speed is greater than that of the multi-book delivery and transmission mechanism 1, forming a book transmission differential speed. The multiple book monitoring and transmission units 5 are arranged in a row and installed at intervals on the rack 2 to form multiple independent book monitoring and transmission channels with the same transmission direction. When each book monitoring and transmission unit 5 detects that there are books that need to be transmitted in its own book monitoring and transmission channel, it transmits the books that need to be transmitted. The pressure friction wheel assembly 6 is mounted on the frame 2 and located above the plurality of book monitoring and transmission units 5. When there are books being transmitted on any number of book monitoring and transmission channels, the pressure friction wheel assembly 6 applies a first frictional force to the upper surface of the top layer of books being transmitted. The book monitoring and transmission unit 5, which is responsible for transmitting books on the corresponding book monitoring and transmission channel, transports the stacked books and applies a second frictional force to the lower surface of the bottom layer of books. The first frictional force is less than the second frictional force.

[0011] In this embodiment, the multi-book delivery and transmission mechanism 1 has a delivery and transmission area 10 for multiple books. The books in the delivery and transmission area 10 are transmitted in a preset transmission direction, which solves the problem of requiring users to deliver books one by one at the front of the device, which is not suitable for the transmission of randomly scattered books. Users can put multiple books, or even randomly stacked books, into the multi-book delivery and transmission mechanism 1 without having to follow strict single-book or directional delivery rules, effectively avoiding forced constraints on user behavior and greatly improving the convenience and freedom of operation. The book separation component 3 rises slowly on the first gantry 34 at a preset slow rising speed according to the rising drive signal to separate the stacked books. The book separation monitoring device 4 generates the rising drive signal and sends it to the book separation component 3 when it detects that a book has been transmitted to the bottom of the book separation component 3. This solves the problems of manual book separation and rigid transmission methods, and realizes the complete automation and intelligence of the book separation process. When the book separation monitoring device 4 detects the arrival of a book, the book separation component 3 starts to rise. The rising action is slow and controlled at a preset speed, precisely separating multiple stacked books one by one from the bottom layer, allowing the bottom books to pass first. This transforms a randomly placed stack of books into an orderly, single-book flow. Multiple book monitoring and transmission units 5 are located at the book output end of the multi-book delivery and transmission mechanism 1, and their book transmission speed is greater than that of the multi-book delivery and transmission mechanism 1, forming a differential book transmission speed. These multiple book monitoring and transmission units 5 are arranged in a row, spaced apart on the rack 2, forming multiple independent book monitoring and transmission channels with the same transmission direction. When each book monitoring and transmission unit 5 detects a book in its own channel that needs to be transmitted, it transmits the book. This solves a series of rigid transmission problems, such as only being able to transmit books placed in a fixed direction after manual separation, the inability to automatically start and stop the transmission channel, and the inability to flexibly select different delivery directions for book transmission. First, the differential speed design allows books to be quickly spaced out as they enter the specific book transport channels of multiple book monitoring and transport units 5 from the multi-book delivery and transport mechanism 1, effectively dispersing them and preventing congestion. Second, multiple independent book monitoring and transport channels form a parallel processing system, significantly improving overall throughput efficiency. Most importantly, each book monitoring and transport unit 5 operates by transmitting books only when it detects that a book has entered its specific transport channel and needs to be transported. This allows for on-demand start / stop and precise control; the system only powers and operates on channels with books in them, while empty channels remain stationary. This not only effectively solves the energy waste problem of traditional belt conveyors 11 idling and enables flexible selection of transport channels, but also adapts to random incoming materials of varying sizes and shapes, demonstrating extremely high adaptability and flexibility.When books are being transported on any number of book monitoring and transmission channels, the downward friction wheel assembly 6 applies a first frictional force to the upper surface of the top stacked book during transport. Meanwhile, the book monitoring and transmission unit 5, responsible for transporting books on the corresponding channel, carries the stacked books and applies a second frictional force to the lower surface of the bottom book. Since the first frictional force is less than the second, this process solves the problem of potentially remaining stacked books on the transmission channel, enabling further automatic dispersal and rapid separation. This is the third and final precision separation step in the entire system. It cleverly utilizes the principle of friction difference: the lower book monitoring and transmission unit 5 provides a strong driving force (second frictional force) to propel the bottom book forward, while the upper friction wheel 62 applies a smaller resistance force (first frictional force). When two books pass together, this force difference causes the top book to lag behind the bottom book, effectively intercepting and dispersing it for transport. This process is completely automatic, continuous, and efficient, ensuring that the final output is a completely separated single book.

[0012] It is important to note that in this embodiment, the book separation component 3 is a macroscopic obstruction design that slowly rises on a gantry. It physically blocks all upper-layer books except the bottom layer, and uses the slow upward motion to pull the bottom layer books out by the conveyor mechanism, thus breaking up and separating a stack of books. However, this separation is batch-based and sequential, and cannot handle accidental stacking or tilting that may occur during rapid transport due to factors such as smooth book surfaces, size differences, or speed variations. The cooperation between the downward friction wheel component 6 and the book monitoring and conveying unit 5 can effectively solve these problems. The separation principle of the downward friction wheel component 6 is no longer the mechanical obstruction of the book separation component 3, but rather based on precise control of friction. By setting the first friction force to be less than the second friction force, the system can create a clever force field: the conveyor unit below the books provides a strong driving force, propelling the bottom layer books in contact with it forward rapidly, while the friction wheel 62 above the books provides a smaller resistance force acting on the top layer books. When books are stacked, the force difference causes the top book to move slower than the bottom book, thus separating them and leaving them behind, waiting to be transported individually by the transmission unit below. Furthermore, it is particularly important to note that in this embodiment, the speed difference and friction difference together form a three-dimensional, all-around separation protection network. The speed difference is a speed step between different transmission segments, used to increase the horizontal distance between books; while the friction difference is a continuous force acting on the top and bottom surfaces of the stacked books within the same transmission channel, used to eliminate vertical stacking. In addition, the system physically divides the subsequent transmission path of the book separation component 3 into multiple independent book monitoring and transmission channels with the same transmission direction. Each book monitoring and transmission unit 5 only transmits the book that needs to be transmitted when it detects that there is a book in its own channel. The system no longer needs to idle the entire transmission line for potentially arriving books. Book transmission in a specific channel only starts when a book actually enters that channel. This brings direct technical benefits such as energy saving, low noise (avoiding idle friction and vibration), and reduced mechanical wear. Moreover, the system can handle books entering any channel from any position and in any horizontal orientation (within the width of the device), adapting well to the randomness of book placement during random scattering.

[0013] It should be noted that the books in the delivery and transmission area 10 can be queued and transmitted in a preset transmission direction. Adjacent batches of books are separated sequentially by the book separation assembly 3, separated again by the pressure friction wheel assembly 6, and transmitted by the transmission unit that senses the books in the multiple book monitoring and transmission units 5.

[0014] Preferably, the first gantry 34 is installed on the upper side of the frame 2, forming an inverted U-shaped space above the frame 2, and the upward movement of the book separation assembly 3 is located within the U-shaped space. The specific structure of the first gantry 34 may include a crossbeam 340, a first column 341, and a second column 342; the two bottom ends of the first column 341 and the second column 342 are respectively connected to two mounting positions on the upper side of the frame 2, and the two top ends of the first column 341 and the second column 342 are respectively connected to the two ends of the crossbeam 340, thereby forming the U-shaped space above the frame 2.

[0015] Preferably, the book separation assembly 3 includes a baffle 30, a lifting and sliding assembly 31, a limit switch 32, and a lifting drive device 33; the lifting drive device 33 is installed on the crossbeam 340 and connected to the baffle 30, the baffle 30 is connected to the column of the first gantry frame 34 through the lifting and sliding assembly 31, the limit switch 32 is installed on the column of the first gantry frame 34 and is connected to the lifting drive device 33 for communication; the lifting drive device 33 drives the baffle 30 to slowly rise below the crossbeam 340 at a preset slow rising speed according to the rising drive signal, so as to separate the stacked books. The lifting drive device 33 includes a motor body 330 and a motor lead screw 331. The motor body 330 is mounted on the crossbeam 340 and connected to the baffle 30 via the motor lead screw 331. The limit switch 32 is connected to the motor body 330 for communication. The motor body 330 drives the motor lead screw 331 to move according to the lifting drive signal. The movement of the motor lead screw 331 drives the baffle 30 to slowly rise below the crossbeam 340 at a preset slow rising speed. The lifting sliding assembly 31 includes a lifting slider 310 and a vertical slide rail 311. The lifting slider 310 is fixed to the baffle 30, and the vertical slide rail 311 is fixed to the column of the first gantry frame 34. The lifting slider 310 is slidably connected to the vertical slide rail 311 through its own groove.

[0016] Preferably, the book separation monitoring device 4 uses a photoelectric detection sensor. When the photoelectric detection sensor detects that a book has been transferred to the bottom of the book separation component 3, it generates the upward drive signal and sends it to the book separation component 3.

[0017] It should be noted that after the upward drive signal is sent to the book vertical separation component 3, the book vertical separation component 3 can slowly rise to a preset height and then stop rising.

[0018] Improvedly, the book separation monitoring device 4 cooperates with the plurality of book monitoring and transmission units 5 to control the rising and stopping of the book separation component 3. When the book separation monitoring device 4 detects that a book has been transferred to the bottom of the book separation component 3, it generates a rising drive signal and sends it to the book separation component 3, so that the book separation component 3 rises slowly at a preset slow rising speed. When any number of the plurality of book monitoring and transmission units 5 detects that there is a book to be transferred in their respective book monitoring and transmission channels, they send a rising stop signal to the book separation component 3 while transferring the book to be transferred, so that the book separation component 3 stops rising. It should be noted that, in this embodiment, through the cooperation of the book separation monitoring device 4 and the plurality of book monitoring and transmission units 5, not only can the transfer of books be controlled, but also the rising and stopping of the book separation component 3 can be controlled, thereby simplifying the structure and reducing costs. Moreover, it enables intelligent linkage between the plurality of book monitoring and transmission units 5 and the book separation component 3, improving the intelligent collaborative control of book transfer.

[0019] Furthermore, the book monitoring and transmission unit 5 is equipped with a book discharge detection sensor 7 at its discharge port to monitor the book discharge status.

[0020] Preferably, the multi-book delivery and transmission mechanism 1 includes a belt conveyor 11 and a book delivery fence 12 mounted on the frame 2. The book delivery fence 12 surrounds the transmission belt 514 of the belt conveyor 11, and together with the transmission belt 514, forms the delivery and transmission area 10 capable of delivering multiple books. The books located in the delivery and transmission area 10 are transported in a preset transmission direction via the transmission belt 514 of the belt conveyor 11. Furthermore, the book delivery fence 12 includes a first horizontal plate 120, a second horizontal plate 121, a first lateral plate 122, and a second lateral plate 123. The first horizontal plate 120, the first lateral plate 122, and the second lateral plate 123 form a U-shaped frame with an opening facing the preset transmission direction on three sides of the conveyor belt 514. The second horizontal plate 121 connects the first lateral plate 122 and the second lateral plate 123 at the opening of the U-shaped frame. The bottom surface of the second horizontal plate 121 is separated from the surface of the conveyor belt 514 by a preset book passage height. This book passage height allows books of a second preset thickness to pass through the conveyor belt 514 under transmission, thus initially breaking up stacked books. The second preset thickness is greater than the first preset thickness. Furthermore, baffles are adhered to positions on the conveyor belt 514 at preset intervals to prevent books from moving backward during transmission.

[0021] It should be noted that the belt conveyor 11 and the book delivery fence 12 together form the delivery and transmission area 10, which can accommodate multiple books. This allows users to freely and repeatedly deliver multiple books, and prevents books from slipping off the belt side during the initial transmission, ensuring that all delivered books are guided to the preset transmission direction. The bottom surface of the second horizontal plate 121 is separated from the surface of the conveyor belt 514 by a preset book passage height, which can achieve initial scattering and overload protection. Before the books reach the book separation assembly 3, the book passage height acts as the first physical screening, allowing only books of a second preset thickness (such as the thickness of a preset number of stacked books or the thickness of a single book of a preset thickness) to pass through the book passage height. When a user delivers a stack of books that is too tall, the bottom few books will be pulled out by the belt and pass through the book passage height first, while the upper books are blocked and scattered by the second horizontal plate 121, reducing the workload of the book separation assembly 3 behind. In this embodiment, by limiting the thickness of books simultaneously entering the book separation component 3, the jamming of the book separation component 3 or the congestion of the conveyor belt 514 caused by a single influx of excessively thick books is effectively avoided. Specifically, the second preset thickness is greater than the first preset thickness; coarse separation is first performed by the barrier, followed by fine separation by the separation component, making the process more scientific and reasonable. Furthermore, baffles are adhered to the surface of the conveyor belt 514 at preset intervals. These baffles prevent books from sliding backward during transport, ensuring stable unidirectional transport. At the moment the belt starts, stops, or changes speed, and when the friction coefficient between the belt surface and the book cover material (which may be very smooth) is insufficient, books may slip, slide backward, or remain stationary. The baffles can grip the rear edge of the book, ensuring that the book achieves a positive and effective displacement in each cycle of the belt's movement.

[0022] Preferably, each of the plurality of book monitoring and transmission units 5 includes a book loading level detection sensor 50 and a belt conveyor assembly 51. The book loading level detection sensor 50 is mounted on the frame 2 via a mounting plate assembly 52 and is located at the loading inlet of the belt conveyor assembly 51. The belt conveyor assembly 51 is mounted on the frame 2 via a mounting box assembly 53. The mounting plate assembly 52 includes an L-shaped mounting plate 520 and a supporting beam 521. All the book loading level detection sensors 50 are mounted on the upper side of the L-shaped mounting plate 520. The lower side of the L-shaped mounting plate 520 is fixedly mounted to the supporting beam 521. Both ends of the supporting beam 521 are fixedly mounted to the two sides of the frame 2. The mounting box assembly 53 includes a mounting box 530 and a support shaft 531. The support shaft 531 is mounted on the mounting box 530, and the mounting box 530 is mounted on the frame 2. The belt conveyor assembly 51 is mounted on the mounting box 530 and the support shaft 531. The mounting box 530 includes a bottom plate 5300 and a side plate 5301. The bottom plate 5300 is connected to the side plate 5301, the side plate 5301 is connected to the frame 2, and the support shaft 531 is connected to the side plate 5301. The belt conveyor assembly 51 is mounted on the side plate 5301 and the support shaft 531. The belt conveyor assembly 51 includes a motor 510, a drive pulley 511, a driven pulley 512, a drive belt 513, and a transmission belt 514. The motor 510 is mounted on the bottom plate 5300 of the box via a mounting base. The shaft of the motor 510 is connected to the drive pulley 511. The drive pulley 511 and the driven pulley 512 are rotatably connected via the drive belt 513. The driven pulley 512 is rotatably connected to the support shaft 531 and rotatably connected to the transmission belt 514. The motor 510 drives the drive belt 513 to rotate via the drive pulley 511. The drive belt 513 then drives the driven pulley 512 to rotate. The driven pulley 512 ultimately drives the transmission belt 514 to rotate. When the transmission belt 514 rotates, it forms a transmission channel for transporting books. The supporting shaft 531 includes a first supporting shaft 5310 and a second supporting shaft 5311 separated by a preset transmission distance. The driven wheel 512 includes a first driven wheel 5120 and a second driven wheel 5121 rotatably connected via the transmission belt 514. The first driven wheel 5120 or the second driven wheel 5121 is rotatably connected to the driven wheel 512 via the driving belt 513. A book loading level detection sensor 50 is provided on one side of the first supporting shaft 5310. Each book loading level detection sensor 50 is located on one side of the first driven wheel 5120 in the corresponding belt transmission assembly 51. The second driven wheel 5121 in each belt transmission assembly 51 is rotatably connected to the driving wheel 511 via the driving belt 513.

[0023] It should be noted that in this embodiment, the monitoring and transmission execution functions are encapsulated within each independent unit. Each channel is an intelligent unit capable of independently monitoring (via the book detection sensor 50 at the loading position) and executing transmission (via the belt conveyor assembly 51), enabling adaptive on-demand start and stop of transmission only when it detects that there are books to be transmitted in its channel. Furthermore, the conveyor belt 514 needs to provide a stable and sufficient secondary friction force to the lower surface of the books. In this embodiment, a robust mounting box 530 and double-supported rotating shafts 531 ensure a flat and stable transmission surface. Additionally, the motor 510 can drive the driven wheel 512, which is further away, via the drive belt 513. This allows for more flexible installation of the motor 510, eliminating the need for complete alignment with the book transmission path and helping to optimize the internal space utilization of the mounting box 530, achieving a compact structure. By setting up the drive wheel 511 and driven wheel 512, graded transmission can be achieved, increasing torque or adjusting speed, ensuring that the conveyor belt 514 has sufficient power to overcome the weight of the books and the resistance of the friction wheel 62, reliably dragging the books forward. The second driven pulley 5121 is connected to the driving pulley 511 via the driving belt 513, while the first driven pulley 5120 is mainly responsible for supporting and tensioning the transmission belt 514. This division of labor makes the power transmission path clear and efficient, reducing transmission losses. In addition, the book loading level detection sensor 50 is set on one side of the first support shaft 5310 and on one side of the first driven pulley 5120 in the corresponding belt transmission assembly 51, which can realize the instantaneous and accurate detection of the arrival of books.

[0024] Preferably, the downward pressure friction wheel assembly 6 includes a second gantry frame 60, a downward pressure arm assembly 61, and a plurality of friction wheels 62. The downward pressure arm assembly 61 is suspended at the upper end of the second gantry frame 60, and the lower end of the second gantry frame 60 is connected and fixed to the frame 2. The plurality of friction wheels 62 are distributed on the lower side of the downward pressure arm assembly 61, and provide contact friction with the upper surface of the top layer of books stacked during transmission. Further, when the plurality of friction wheels 62 are distributed on the lower side of the downward pressure arm assembly 61, one row of friction wheels 62 is distributed in the entrance area of ​​the plurality of book monitoring and transmission channels to form an entrance friction wheel group 62, and another row of friction wheels 62 is distributed in the exit area of ​​the plurality of book monitoring and transmission channels to form an exit friction wheel group 62, so that each book monitoring and transmission channel has one friction wheel 62 at both the entrance and exit positions. Furthermore, the inlet friction wheel 62 group is disposed on the inlet rotating shaft on the lower side of the lower pressure arm assembly 61, and each friction wheel 62 in the inlet friction wheel 62 group is rotatably connected to the inlet rotating shaft; the outlet friction wheel 62 group is disposed on the outlet rotating shaft on the lower side of the lower pressure arm assembly 61, and each friction wheel 62 in the outlet friction wheel 62 group is rotatably connected to the outlet rotating shaft.

[0025] It should be noted that when the multiple friction wheels 62 are distributed on the lower side of the pressure arm assembly 61, one row of friction wheels 62 is distributed in the entrance area of ​​the multiple book monitoring and transmission channels to form an entrance friction wheel group 62, and another row of friction wheels 62 is distributed in the exit area of ​​the multiple book monitoring and transmission channels to form an exit friction wheel group 62. This can achieve full-process, blind-angle separation protection during the transmission process. When a book enters the high-speed independent channel from the public area (on the multi-book delivery and transmission mechanism 1), the entrance friction wheel group 62 acts as the first precise separation defense line, immediately processing any books that may be stacked upon entering the channel. When the book transmission is about to end and is about to enter the next stage, the exit friction wheel group 62 acts as the final quality inspection and protection defense line, capturing and separating any new stacking that may have occurred due to vibration or other reasons during the channel transmission process, ensuring that the output book is completely single-copy. In addition, this embodiment uses a single rotating shaft instead of multiple independent shafts and bearing seats, greatly simplifying the mechanical structure, reducing the number of parts, and improving installation accuracy and overall structural rigidity. All friction wheels 62 mounted on the same rotating shaft exert uniform and consistent pressure on the book surface, ensuring the uniformity of the first friction force across the entire channel width and preventing separation failure or book deviation due to uneven pressure. In this embodiment, each friction wheel 62 can rotate independently around the rotating shaft. When the book surface is uneven or the book thickness varies, each friction wheel 62 can rotate independently and maintain contact with the book cover, adapting to the undulations of the book surface and ensuring the continuous and effective application of friction force. In addition, the second gantry 60 ensures that the downward pressure applied to the book is vertical and stable, and will not sway significantly due to vibrations during transmission, thereby ensuring the constancy of the first friction force. The entire downward pressure arm assembly 61 (along with all the friction wheels 62 on it) can be adjusted in height or friction force as a whole. For example, the downward pressure height of the downward pressure arm assembly 61 can be adjusted to accommodate books of different thicknesses, precisely controlling the magnitude of the first friction force so that it is always stably less than the second friction force provided by the lower transmission belt 514.
