Description

Technical Field

[0001] This invention relates to the field of intelligent library technology, specifically to intelligent library bookshelves. Background Technology

[0002] Most existing library bookshelves use a traditional open horizontal shelf structure, with books arranged horizontally on each shelf platform. Limited by the height range for manual access, the upper shelves are often left unused or used only for infrequently used books, resulting in low vertical space utilization and significantly restricting the library's collection capacity. While some libraries have automated storage and retrieval systems, these systems are often installed separately from conventional shelves, failing to achieve organic integration. This results in large footprints, an uncompacted spatial layout, and the need for climbing tools to retrieve and return books from the upper shelves, posing safety hazards.

[0003] Existing automated bookshelves mostly employ rigid push-out mechanisms, lacking effective cushioning protection when books are pushed out, making their spines and covers susceptible to impact damage. The docking precision between the retrieval and storage components is insufficient, and the positioning detection methods are simplistic, easily leading to misalignment and jamming, causing books to become stuck or fall. Current bookshelves rely heavily on manual recording or simple barcode scanning for book identification and storage location management, resulting in delayed information updates and frequent misplacement or omissions. Furthermore, the flipping mechanisms of existing automated bookshelves lack stability, causing books to shift when switching between horizontal and vertical positions, and the connection with the conveyor system is not smooth enough, affecting the overall automation level of the book storage, retrieval, and return process. Summary of the Invention

[0004] The technical problem to be solved by this invention is to overcome the shortcomings of traditional bookshelves, such as low utilization of high-level space, inability to integrate automated storage and retrieval with ordinary bookshelves, lag in manual entry of storage location information, misalignment and jamming of storage and retrieval connections, and unsmooth connection of book flipping and conveying, and to provide intelligent bookshelves for libraries.

[0005] This invention is achieved through the following technical solution: The intelligent bookshelf of the library of this invention includes a support frame, in which multiple platform panels are fixed. Self-service books are arranged on the lower platform panels, and multiple storage components are arranged on the higher platform panels. Books are stored in the storage components. A slide rail is fixed to the top of the support frame, and a first linear module is fixed to the side of the support frame. A frame that moves back and forth is provided on the slide rail and the first linear module. The frame is poweredly connected to the first linear module. A retrieval component opposite to the storage components is fixed on the frame. A conveying component is also provided on one side of the support frame to convey the books. An electric push rod opposite to the retrieval component is fixed on the frame.

[0006] In a further technical solution, a push block is fixed to the front side of the electric push rod. After the electric push rod is activated, it pushes the push block through the storage component and moves the book into the storage component in an empty state.

[0007] In a further technical solution, the storage component includes a body with an inner cavity. The book is placed in the inner cavity. The top of the body has a mounting bracket at the front and a mounting bracket at the back. A push plate is provided between the mounting brackets. The push plate abuts against the left side of the book. A slide rod is fixed on the push plate. The slide rod slides through the mounting bracket. A baffle is fixed at the end of the slide rod.

[0008] A further technical solution is provided, wherein a guide rail is fixed to the lower inner wall of the mounting bracket, a third slider is slidably mounted on the guide rail, the third slider is fixedly connected to the push plate, a moving rod is fixed to the top inner side of the mounting bracket, a moving block is fixed inside the push plate, and the moving block is slidably connected to the moving rod.

[0009] In a further technical solution, retaining rings are slidably provided at both ends of the moving rod, and a spring is elastically provided between the retaining rings and the inner wall of the mounting bracket.

[0010] In a further technical solution, the storage and retrieval component includes a base and a flipping frame. A rotating component that drives the flipping frame to rotate is fixed inside the base. A storage cavity is opened inside the flipping frame. A through hole is provided on one side of the storage cavity. A second linear module is fixed on the front and rear sides of the flipping frame. A stand is fixed on the moving part of the second linear module. A clamping block assembly for clamping the baffle is provided on the stand.

[0011] A further technical solution includes a rotating component comprising a base block fixed to the bottom of the tilting frame, the base block being rotatably connected to the base, and a reducer motor being fixed to one side of the base, the reducer motor being poweredly connected to the base block.

[0012] A further technical solution includes a clamping block assembly comprising a stepper motor fixed to the top of the stand, a clamping block fixed on the output shaft of the stepper motor, a second groove being provided in the clamping block, and a first groove being provided on one side of the second groove.

[0013] A further technical solution includes a conveying assembly comprising a first conveyor, a second conveyor, and a third conveyor, wherein multiple baffles are fixed on the conveyor belt of the first conveyor, and a protrusion is fixed on the top of the book.

[0014] Further technical solutions include RFID tags fixed to the side of the book, a proximity switch fixed to the right side of the machine body, multiple RFID barcode readers fixed inside the frame, the RFID barcode readers being opposite to the shelf, an end RFID card reader fixed on the third conveyor, and a side plate fixed to the bottom of the flipping frame.

[0015] The beneficial effects of this invention are as follows: First, by combining the automated storage and retrieval mechanism with the conventional self-service bookshelf, and with the vertical spatial layout of the multi-layer platform, the linkage and docking of the storage and retrieval components, the connection and transition of the conveying components, and the information management of the intelligent terminal, the invention achieves the technical effects of effective utilization of high-level space, full automation of the storage, retrieval and return process, accurate and reliable book identification, and real-time updates of storage space management. This effectively overcomes the shortcomings of existing library bookshelves, such as wasted vertical space, low degree of automation, easy damage to books, and information lag.

[0016] Second, the lower platform shelves are arranged to hold self-accessible books, while the upper platform shelves are arranged to hold storage components. This allows the bookshelves to meet the needs of people to easily access frequently used books in the lower area without the need for climbing tools. At the same time, the automated mechanism makes full use of the vertical space in the upper area, significantly improving the collection capacity and space utilization rate, and realizing the organic integration of automated bookshelves and conventional bookshelves.

[0017] Third, the frame achieves stable forward and backward movement through the cooperation of the first linear module and the slide rail. After the storage component and the retrieval component are aligned, the clamping block component and the baffle are linked to drive the push plate to smoothly push the book into the storage component. During the movement of the push plate, after contact with the retaining ring, the spring is compressed and buffered, avoiding rigid impact when the book is pushed out, effectively protecting the spine and cover, and extending the service life of the book.

[0018] Fourth, the flipping frame in the storage and retrieval component uses a reducer motor to drive the base block to flip, enabling reliable switching between vertical storage and horizontal transport of books. Combined with the through-hole and RFID barcode reader to scan and identify book tags, it realizes real-time verification of book information during storage and retrieval, ensuring the correctness of book retrieval and the accuracy of storage location information, and avoiding mis-retrieving or misplacement.

[0019] Fifth, the conveying components are connected in sequence by the first, second and third conveyors. By using the abutment between the baffle and the protrusion on the top of the book, the book is smoothly brought out from the storage and retrieval components and transported to the book retrieval point. The reverse operation can also complete the return of the book, realizing the automated flow of books between the storage and retrieval end and the retrieval and placement end, reducing manual intervention and improving borrowing efficiency.

[0020] 6. The proximity switch works in conjunction with the side plate to transmit a signal when the access component and the storage component are in relative positions, so that the first linear module stops precisely, ensuring the accuracy of the docking between the two, avoiding jamming and damage to the books caused by misalignment, and improving the reliability of the equipment operation.

[0021] VII. The intelligent terminal deploys a large AI model locally on a PC and connects to the intranet cloud platform, enabling intelligent interactive recommendations with personnel. It automatically issues control commands based on the storage location information and book data in the cloud platform. After the device executes the commands, it provides real-time feedback and updates, keeping the storage location status and book information synchronized. This effectively avoids misplacement and omissions, and improves the level of intelligence in book management and borrowing efficiency.

[0022] 8. When returning books, the book tags are scanned and verified by the end RFID reader. The electric push rod drives the push block to smoothly push the book from the storage component into the empty storage component. Combined with the secondary confirmation by the RFID barcode reader, the return action is only executed when the storage location information and tag information match the instructions. This ensures the accuracy and security of book returns and realizes closed-loop management of the entire process of storing, retrieving, and returning books. Attached Figure Description

[0025] like Figures 1-12 As shown, the present invention will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The directions of the projection relationship are consistent in all directions: up, down, left, right, front, and back.

[0026] In embodiment one, the intelligent bookshelf of the present invention includes a support 11, with multiple platform plates 17 fixed inside the support 11. Self-service books 18 are arranged on the lower platform plate 17, and multiple storage components 12 are arranged on the higher platform plate 17. Books 22 are stored in the storage components 12. A slide rail 13 is fixed to the top of the support 11, and a first linear module 14 is fixed to the side of the support 11. A frame 15 that moves back and forth is provided on the slide rail 13 and the first linear module 14. The frame 15 is poweredly connected to the first linear module 14. A retrieval component 16 opposite to the storage component 12 is fixed on the frame 15. A conveying component is also provided on one side of the support 11 to convey the books 22. An electric push rod 43 opposite to the retrieval component 16 is fixed on the frame 15.

[0027] Advantageously, a push block 45 is fixed to the front side of the electric push rod 43. After the electric push rod 43 is working, it pushes the push block 45 through the storage component 16 and moves the book 22 into the storage component 12 in an empty state.

[0028] Advantageously, a first slider 46 is fixed to the top of the frame 15, and the first slider 46 is slidably connected to the slide rail 13. A second slider 41 is provided at the bottom of the frame 15, and the second slider 41 is fixedly connected to the moving part of the first linear module 14. This forms a stable transmission mechanism, making the frame 15 more stable when moving back and forth, and enabling the first linear module 14 to better drive the frame 15 and the access component 16 to move back and forth.

[0029] Advantageously, a shelf 42 is fixed to one side of the frame 15, and the access component 16 is installed and fixed on the shelf 42.

[0030] When book 22 is taken out, the first linear module 14 drives the frame 15 to move back and forth on the slide rail 13 and the first linear module 14. When the access component 16 on one side of the frame 15 is opposite to the storage component 12, the access component 16 works and docks with the storage component 12. The storage component 12 pushes out the book 22 and puts it into the access component 16. Then the first linear module 14 drives the frame 15 and the access component 16 to move to the front. The access component 16 rotates the book 22 forward by 90°, so that the conveying component carries the book 22 away from the access component 16 and conveys it to the book retrieval point.

[0031] When returning book 22, the staff places book 22 into the retrieval area. After the conveying component works, it brings book 22 back to the storage component 16 and pushes it back into the storage component 16. The storage component 16 rotates book 22 90° backward to keep it vertical. Then, the first linear module 14 moves the frame 15 and the storage component 16, so that the storage component 16 moves book 22 to the side of the empty storage component 12. Then, after the electric push rod 43 works, its push rod and push block 45 push book 22 into the empty storage component 12.

[0032] Example 2, based on Example 1, further defines the following: The storage component 12 includes a body 21, an inner cavity 24 is opened inside the body 21, the book 22 is placed in the inner cavity 24, a mounting bracket 33 is fixed at the top of the body 21 at the front and back, a push plate 35 is arranged between the mounting brackets 33, the push plate 35 abuts against the left side of the book 22, a slide rod 28 is fixed on the push plate 35, the slide rod 28 slides through the mounting bracket 33, and a baffle 26 is fixed at the end of the slide rod 28.

[0033] Advantageously, a guide rail 37 is fixed to the lower inner wall of the mounting bracket 33, a third slider 36 is slidably arranged on the guide rail 37, the third slider 36 is fixedly connected to the push plate 35, a moving rod 29 is fixed to the top inner side of the mounting bracket 33, a moving block 31 is fixed inside the push plate 35, and the moving block 31 is slidably connected to the moving rod 29.

[0034] Advantageously, the moving rod 29 is provided with retaining rings 32 at both ends, and a spring 34 is elastically provided between the retaining rings 32 and the inner wall of the mounting bracket 33.

[0035] When book 22 is removed, the access component 16 clamps the baffle 26, then moves the baffle 26, slide bar 28, push plate 35, moving block 31, and third slider 36 to the right. This causes the push plate 35 to push the book 22 out of the opening of the inner cavity 24 and into the access component 16. When the push plate 35 contacts the retaining ring 32 on the right side, the spring 34 is compressed, which acts as a buffer. Then, the access component 16 moves the baffle 26, slide bar 28, push plate 35, moving block 31, and third slider 36 to the left to reset. After that, the access component 16 releases the lock between itself and the baffle 26, and then the access component 16 resets.

[0036] Example 3, based on any one of Examples 1 to 2, further defines the following: the storage component 16 includes a base 51 and a flipping frame 54. A rotating component that drives the flipping frame 54 to rotate is fixed inside the base 51. A storage cavity 64 is opened inside the flipping frame 54. A through hole 55 is provided on one side of the storage cavity 64. A second linear module 62 is fixed on the front and rear sides of the flipping frame 54. A stand 61 is fixed on the moving part of the second linear module 62. A clamping block assembly for clamping the baffle 26 is provided on the stand 61.

[0037] Advantageously, the rotating assembly includes a base block 52 fixed to the bottom of the tilting frame 54, the base block 52 being rotatably connected to the base 51, and a reducer motor 53 being fixed to one side of the base 51, the reducer motor 53 being poweredly connected to the base block 52.

[0038] After the reducer motor 53 works, it drives the base block 52 and the flipping frame 54 to flip, which in turn indirectly drives the books 22 in the flipping frame 54 to flip.

[0039] Advantageously, the clamping block assembly includes a stepper motor 56 fixed to the top of the stand 61, a clamping block 57 fixed on the output shaft of the stepper motor 56, a second groove 59 is provided in the clamping block 57, and a first groove 58 is provided on one side of the second groove 59.

[0040] When the first slot 58 is horizontally positioned, the second linear module 62 drives the stand 61 and the locking block 57 to move to the left, so that after the first slot 58 passes through the baffle 26, the baffle 26 is located in the second slot 59. Then, the locking block 57 is driven by the stepper motor 56 to rotate 90°, so that the baffle 26 abuts against the left end wall of the second slot 59. At this time, the baffle 26 and the locking block 57 are locked and fixed. Then, the second linear module 62 drives the stand 61, the locking block 57, the baffle 26, the slide rod 28, the push plate 35, the moving block 31 and the third slider 36 to move to the right, so that the push plate 35 pushes the book 22 into the storage cavity 64. Then, the second linear module 62 drives the stand 61, the locking block 57, the baffle 26, the slide bar 28, the push plate 35, the moving block 31 and the third slider 36 to move to the left to reset. Then, after the stepper motor 56 works, it drives the locking block 57 to rotate 90°, so that the baffle 26 is opposite to the first groove 58. Then, after the second linear module 62 works, it drives the stand 61 and the locking block 57 to reset to the right.

[0041] When the book 22 is placed on the conveyor assembly, the reducer motor 53 drives the base block 52 to swing forward, swinging the flipping frame 54 to a horizontal position. At this time, the book 22 is exposed in the flipping frame 54. After the book 22 comes into contact with the conveyor assembly, the book 22 can be taken out of the flipping frame 54.

[0042] Example 4, based on any one of Examples 1 to 3, further defines the following: the conveying assembly includes a first conveyor 71, a second conveyor 72 and a third conveyor 74. The first conveyor 71, the second conveyor 72 and the third conveyor 74 are existing technologies and are set on the outlet side of the equipment. Multiple baffles 76 are fixed on the conveyor belt of the first conveyor 71 and a protrusion 75 is fixed on the top of the book 22.

[0043] After the book 22 is placed horizontally from vertical, the protrusion 75 abuts against one side of the baffle 76. After the first conveyor 71 starts working, the protrusion 75 and the book 22 move along the conveyor belt of the first conveyor 71, so that the book 22 moves in the order of the first conveyor 71, the second conveyor 72 and the third conveyor 74. A book frame is set on one side of the third conveyor 74, and the book 22 falls into the book frame.

[0044] When returning the book, adjust the book 22 so that the protrusion 75 faces forward and place it on the third conveyor 74. The third conveyor 74 moves the book 22 to the second conveyor 72, and then from the second conveyor 72 to the first conveyor 71. After the baffle 76 abuts against the front of the protrusion 75, put the book 22 into the horizontally set flipping frame 54. A proximity switch can be set at the bottom of the flipping frame 54 to sense the arrival of the book 22. When the proximity switch is triggered, the controller drives the reducer motor 53 to rotate, so that the flipping frame 54 quickly comes to a vertical position, preventing the baffle 76 at the arrival port of the book 22 from continuously squeezing the protrusion 75, causing the book 22 to deform, or causing the first conveyor 71 to jam.

[0045] Then, the first linear module 14 moves the frame 15 and the access component 16 to the side of the storage component 12 in the empty compartment. After that, the electric push rod 43 moves the push block 45 through the access component 16, pushing the corresponding book 22 back into the storage component 12. Then the electric push rod 43 resets, realizing the book return process.

[0046] Example 5, based on any one of Examples 1 to 4, further includes the following: an RFID tag 25 fixed to the side of the book 22, a proximity switch 23 fixed to the right side of the body 21, multiple RFID barcode readers 44 fixed inside the frame 15, the RFID barcode readers 44 being opposite to the shelf 42, an end RFID reader 73 fixed on the third conveyor 74, and a side plate 63 fixed to the bottom of the flipping frame 54.

[0047] Because of the proximity switch 23, when the proximity switch 23 is opposite to the side plate 63, it can transmit the relative positioning information of the storage component 12 and the access component 16, so that the first linear module 14 stops working after receiving the positioning information, and the storage component 12 and the access component 16 are positioned relative to each other.

[0048] When the book 22 is located in the storage cavity 64, the RFID tag 25 is opposite the penetration hole 55. After the RFID barcode reader 44 is working, the RFID tag 25 is read to determine whether the book 22 taken is correct, or to record that the corresponding compartment has stored the book 22 with the tag.

[0049] Example 6, based on any one of Examples 1 to 5, further defines the following: it also includes a smart terminal, which is composed of a PC and includes a monitor, mouse, keyboard and host; the AI ​​intelligent recommendation model is deployed locally on the PC and connected to the cloud platform on the intranet cloud server through an intranet cable, and the device controller is interconnected with the PC through the intranet.

[0050] People interact with the AI ​​model, which makes recommendations based on book information stored in the cloud platform. Once the people have selected the books, the AI ​​model sends the book information to a PC. After the PC starts working, it receives book information from the AI ​​model and searches the database in the cloud platform. The cloud platform stores storage location information and information about the books 22 contained in the storage location. The PC host transmits the information about the books 22 contained in the storage location to the device via network communication. After the device works, it takes out the corresponding book 22 and transmits the storage location information and the information about the book 22 being taken out back to the AI ​​model via network communication. The AI ​​model overwrites the information in the cloud platform to keep the information updated. When returning a book, the person needs to scan the RFID tag 25 with the terminal RFID reader 73. At this time, the PC sends an instruction to the device to place the book 22 with the specified RFID tag 25 into the corresponding storage location based on the empty storage information in the cloud platform. When the device receives the book 22, it scans the RFID tag 25 of the book 22 with the RFID barcode reader 44. The return action is only performed when the storage location information and the information of the RFID tag 25 match the instruction sent by the AI ​​model.

[0051] The self-service books 18 can be retrieved by personnel themselves. The support 11 is quite high, and the storage component 12 is inaccessible to personnel without a ladder. Therefore, this device combines an automated bookshelf with a conventional bookshelf, effectively utilizing vertical space.

[0052] The complete operating steps of the equipment are as follows: Step 1, Book Storage: When all storage components 12 are empty, personnel need to store books into the storage components 12. By reversing the operation of the third conveyor 74, the second conveyor 72, and the first conveyor 71, the end RFID reader 73 scans the RFID tag 25 on the book 22, and then the first conveyor 71 sends it into the storage component 16. After the storage component 16 operates, it switches the book 22 from a horizontal to a vertical position, and the RFID barcode reader 44 scans the RFID tag 25 of the book 22 again to read the information of the book 22. Then, the electric push rod 43 operates, driving the push block 45 to push the book 22 in the storage component 16 into the storage component 12. Thus, the equipment transmits the location information and book 22 information to the PC computer, and the PC computer stores this data in the cloud platform. The equipment ends the book storage stage after all storage components 12 have stored the corresponding book 22. The second step is book retrieval: After personnel interact with the AI ​​model and select the desired book 22, the PC computer converts the storage location information and the book 22 into control commands based on cloud platform data, causing the equipment to operate. The first linear module 14 moves the frame 15 to the corresponding storage location, and then uses the side plate 63 and proximity switch 23 to transmit the positioning information. Then, through the linkage of the storage component 16 and the storage component 12, the book 22 is pushed into the storage component 16. Then, the RFID barcode reader 44 scans the RFID tag 25 on the book 22. The scanned information is transmitted to the PC computer through the equipment to determine whether the book has been retrieved correctly. If correct, the first linear module 14 continues to move the frame 15 and the storage component 16 to the front of the equipment. Then, after the storage component 16 works, it swings the book 22 to a horizontal position, so that the conveying component can move the book 22 and transport it into the book frame. The third step is to return the books: personnel select available storage space information by operating the PC screen, and then use the end RFID reader 73 to scan the RFID tag 25 on the book 22. Since three conveyor components are set up, the books need to be placed manually on the corresponding conveyor components. After verification and scanning by the end RFID reader 73, the book return operation will be performed. The book return operation is the same as the book storage operation.

[0053] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the scope of protection of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
