Description

Technical Field

[0001] This invention relates to the field of book lending machine technology, specifically a library book cart. Background Technology

[0002] Self-service book lending machines are intelligent borrowing devices that allow readers to independently complete tasks such as borrowing and returning books. These machines are typically equipped with touchscreens, scanners, and printers, enabling convenient reading of book information, printing of library cards, and printing of overdue notices. When using self-service book lending machines, readers need to follow library rules and procedures to ensure correct and secure operation.

[0003] Because the barcode recognition system is entirely self-service operated by readers without any staff supervision, and the system only identifies returned books by the barcode affixed to them, book loss can occur if readers accidentally leave books inside their own books. To address this, we propose a library book cart. Summary of the Invention

[0004] The purpose of this invention is to provide a library book cart to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a library book cart, comprising: a book lending machine body, the book lending machine body including a book lending machine box, a book-laying table fixedly mounted on the book-laying table, a V-shaped book-placing seat mounted on the book-laying table, and a book-dropping chamber mounted below the book-laying table.

[0006] It also includes a book-pushing mechanism, which is located inside the book-placing base. The mechanism automatically pushes the scanned books to the designated location and records the number of books.

[0007] The book pressing mechanism is set on the book placement base. It flattens the opened books and controls the operation of the book pushing mechanism by rotating the book placement base.

[0008] The closing mechanism is installed in the book storage room to prevent borrowers from taking out problematic books.

[0009] The book holder has a sliding groove at its V-shaped bottom, two reserved slots on its inner wall, a V-shaped book inlet on its rear side, a book drop opening on the inner bottom wall of the inlet, and the book drop opening is connected to the book drop chamber.

[0010] The book pushing mechanism includes a drive motor, a drive screw is fixedly installed at the output end of the drive motor, and a magnetic plate and a magnetic plate are respectively rotatably installed on the two ends of the drive screw, with the magnetic plate being located at the end away from the drive motor.

[0011] Among them, a drive retaining ring is provided on the side of the magnetic plate two near the drive motor one, and the drive retaining ring is composed of two identical semi-circular ring structures. The thread on the inner wall of the drive retaining ring matches the thread of the drive screw. The upper and lower walls of the drive retaining ring are fixedly provided with closing buckles. The center position of the left and right walls of the drive retaining ring is fixedly provided with side ears. A guide post one is fixedly provided on the side ears. A push spring is sleeved on the outside of the guide post one.

[0012] The inner wall of the closure buckle has a limiting slot, and the wall thickness of the limiting slot gradually increases from left to right. A limiting mechanism is set inside the limiting slot. A magnetic sheet is fixedly set on the left wall of the closure buckle. The magnetic sheet has the same magnetic properties as the second magnetic plate, and the magnetic properties of the second magnetic plate are greater than those of the magnetic sheet.

[0013] An extension post is fixedly installed at the upper left corner of the drive ring, and a book pusher head is rotatably installed on the extension post. A push spring is fixedly installed between the book pusher head and the extension post, and the book pusher head has a triangular prism structure.

[0014] The book pressing mechanism includes a book pressing plate that is rotatably connected to the book placement base. A book pressing head is fixedly installed at the bottom of the book pressing plate. A control switch that is fixedly connected to the book placement base is installed below the book pressing head. A torsion spring is installed at the other end of the book pressing plate, and the book pressing plate is rotatably connected to the book placement base through the torsion spring.

[0015] The closing mechanism includes a closing plate that is slidably connected to the book-dropping room. A limit card is fixedly installed on the closing plate. A guide post 2 passes through the inside of the limit card, and a tension spring is installed on one side of the limit card outside the guide post 2.

[0016] A semi-circular push-slide arm is movably installed at the center of one side of the closing plate. A second drive motor is fixedly installed at one end of the push-slide arm, and the second drive motor is connected to the intelligent system of the main body of the book lending machine through wires.

[0018] The present invention has at least the following beneficial effects:

[0019] In this invention, borrowers unfold books and place them in the book-holding seat in sequence. A book-pressing mechanism flattens the unfolded books, and then a book-pushing mechanism pushes the books from bottom to top into the book inlet. The data already entered into the book-dropping chamber is also recorded. The book-pushing mechanism can only push one book at a time. After each book is pushed out, the next book automatically contacts the book-holding seat, allowing the RFID code on the book to be identified and the information recorded. This automatically organizes the borrowed books and counts them, thus helping to prevent errors in data entry or books being sandwiched between other books, and preventing book theft.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only 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 are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please see Figure 1-13 The present invention provides a technical solution:

[0037] A library book cart includes: a book lending machine body 1, the book lending machine body 1 including a book lending machine box 11, a book-laying table 12 fixedly mounted on the book-laying table 11, a V-shaped book-placing seat 13 mounted on the book-laying table 12, and a book-dropping chamber 15 located below the book-laying table 12.

[0038] It also includes a book pushing mechanism 2, which is located inside the book placement base 13. The book pushing mechanism 2 automatically pushes the scanned books to the designated position and registers the number of books.

[0039] The book pressing mechanism 3 is set on the book placement base 13. The book pressing mechanism 3 flattens the opened book and controls the operation of the book pushing mechanism 2 by rotating the book placement base 13.

[0040] The closing mechanism 4 is installed on the book storage room 15. The closing mechanism 4 prevents borrowers from taking out problematic books.

[0041] Borrowers unfold the books and place them in the book holder 13 one by one. The book pressing mechanism 3 flattens the unfolded books, and then the book pushing mechanism 2 pushes the books into the book inlet from bottom to top.

[0042] In step 14, the data that has been entered is placed into the book drop-off room 15. Each time the book pusher 2 can push one book, the second book automatically contacts the book placement seat 13 after each book is pushed out, thereby identifying the RFID code in the book and entering the information. This automatically organizes the borrowed books and counts the borrowed books, which helps to prevent errors in the information entered or books being stuck in the book, thus preventing theft.

[0043] The book holder 13 has a sliding groove 18 at its V-shaped bottom and two reserved slots 17 on its inner wall. The book holder 13 has a V-shaped book inlet 14 at its rear side and a book drop opening 16 on its inner bottom wall. The book drop opening 16 is connected to the book drop chamber 15. First, the borrower unfolds and places the books they want to borrow in order. Then, they place a stack of unfolded books into the V-shaped bottom of the book holder 13. When the book holder 13 scans the bottom book, the book pusher 2 pushes the scanned book into the book inlet 14 and causes the spine of the book to fall into the book drop opening 16. The book drop opening 16 closes the unfolded books and puts them back together. The closed books then automatically fall into the book drop chamber 15.

[0044] Example 2

[0045] The book pushing mechanism 2 includes a drive motor 21. A drive screw 22 is fixedly installed at the output end of the drive motor 21. A magnetic plate 25 and a magnetic plate 27 are respectively rotatably installed on the two ends of the drive screw 22, and the magnetic plate 27 is located at the end away from the drive motor 21.

[0046] A drive retaining ring 26 is provided on the side of the magnetic plate 27 near the drive motor 21. The drive retaining ring 26 is composed of two identical semi-circular ring structures. The threads on the inner wall of the drive retaining ring 26 match the threads of the drive screw 22. Closing buckles 29 are fixedly provided on the upper and lower walls of the drive retaining ring 26. Side ears 28 are fixedly provided at the center of the left and right walls of the drive retaining ring 26. Guide posts 23 are fixedly provided on the side ears 28. Push springs 24 are sleeved on the outside of the guide posts 23. When the book pressing mechanism 3 presses on the book, it controls the drive motor 21 to work and drive the drive screw 22 to rotate. This drives the drive retaining ring 26 and the book pusher head 202 to move towards the book inlet 14. The book pusher head 202 pushes the book with the bottom information scanned into the book inlet 14, which is beneficial for centralized processing of the scanned books and automatically pushes the scanned books to the designated position.

[0047] The inner wall of the closure buckle 29 has a limiting slot 205, and the wall thickness of the limiting slot 205 gradually increases from left to right. A limiting mechanism 5 is installed inside the limiting slot 205. A magnetic sheet 204 is fixedly installed on the left wall of the closure buckle 29. The magnetic properties of the magnetic sheet 204 are the same as those of the second magnetic plate 27, but the magnetic properties of the second magnetic plate 27 are greater than those of the magnetic sheet 204. When the book pusher head 202 pushes the book into the book inlet 14, the closure buckle 29 moves to the side closer to the first magnetic plate 25. Through the magnetic attraction of the first magnetic plate 25 to the limiting mechanism 5, the two tightly pressed closure buckles 29 separate, thereby... The drive retaining ring 26 disengages from the thread of the drive screw 22, and is simultaneously pushed back to its original position by the force of the two push springs 24. When the drive retaining ring 26 approaches the magnetic plate 27, the magnetic plate 27 attracts the limiting mechanism 5, causing the limiting mechanism 5 to slide and re-close the disengaged drive retaining ring 26 to re-adhere to the drive screw 22. This allows for repeated book pushing, automatically processing the scanned books. The intelligent system counts each book pushed and compares the number of books with the number of scans to prevent theft caused by other books being mixed in with the existing ones.

[0048] An extension post 201 is fixedly installed at the upper left corner of the drive ring 26. A book pusher head 202 is rotatably installed on the extension post 201. A push spring 203 is fixedly installed between the book pusher head 202 and the extension post 201. The book pusher head 202 has a triangular prism structure. When the book pusher head 202 pushes the book to reset, the spine of the book presses the inclined surface of the book pusher head 202, which can compress the push spring 203 and make the book pusher head 202 slide in the slide groove 18, thereby preventing the book from being pushed forward.

[0049] The book pressing mechanism 3 includes a book pressing plate 31 rotatably connected to the book placement seat 13. A book pressing head 32 is fixedly installed at the bottom of the book pressing plate 31. A control switch 33 fixedly connected to the book placement seat 13 is installed below the book pressing head 32. A torsion spring 34 is installed at the other end of the book pressing plate 31. The book pressing plate 31 is rotatably connected to the book placement seat 13 through the torsion spring 34. The control switch 33 is connected to the intelligent system of the drive motor 21 and the main body 1 of the book lending machine through wires. When the person puts all the books into the book placement seat 13, the two book pressing plates 31 rotate and press the books tightly, which helps to ensure the flatness of the unfolded pages and can also reduce the phenomenon of page jamming in the book inlet 14, which helps to protect the books.

[0050] When the two book pressing heads 32 are no longer in contact with the control switch 33, the drive motor 21 is activated. When the book scanning is complete, the two book pressing heads 32 re-engage with the control switch 33, and the drive motor 21 stops working, thus achieving the function of automatically detecting whether there are books.

[0051] Example 3

[0052] The closing mechanism 4 includes a closing plate 41 that is slidably connected to the book drop chamber 15. A limit card 42 is fixedly installed on the closing plate 41. A guide post 43 passes through the inside of the limit card 42, and a tension spring 44 is provided on one side of the limit card 42 outside the guide post 43.

[0053] A semi-circular push-slide arm 46 is movably installed at the center of one side of the closing plate 41. A drive motor 45 is fixedly installed at one end of the push-slide arm 46, and the drive motor 45 is connected to the intelligent system of the book lending machine body 1 through a wire. When the number of books pushed by the book pushing mechanism 2 is different from the number of books scanned by the scanning device in the book placement seat 13, the intelligent system controls the closing plate 41 to close and issues an alarm to notify the staff. This helps to ensure the safety of borrowers and reduce the occurrence of book theft.

[0054] When there are no problematic books, the system controls the drive motor 45 to work, which drives the push-slide arm 46 to rotate and disengage from the closing plate 41. The tension spring 44 pulls the closing plate 41 to slide open, which makes it easier for people to take out the borrowed books at once.

[0055] The limiting mechanism 5 includes a central column 51 slidably connected to the limiting slot 205. Limiting discs 54 are fixedly installed at both ends of the central column 51. Magnetic blocks 55 are fixedly installed on the outer side of the limiting discs 54. Guide columns 56 slide through the inside of the magnetic blocks 55. A partition plate 52 is fixedly installed at the center of the central column 51, and several airbags 53 are installed on the partition plate 52. When the driving retaining ring 26 approaches the magnetic plate 25, the magnetic plate 25 attracts the magnetic blocks 55, causing the limiting disc 54 to slide. At the same time, the limiting disc 54 slides to the thin part of the wall of the limiting slot 205. The several airbags 53 push the closing buckles 29 on both sides, causing the driving retaining ring 26 to spring open and disengage from the driving screw 22.

[0056] Example 4

[0057] Based on the above embodiments, a baffle plate 19 is provided on the book inlet 14, and the baffle plate 19 is stepped, with each step rotatably connected to each other. A book-topping mechanism 6 is fixedly provided on the front side of the extension column 201. The book-topping mechanism 6 includes an L-shaped guide bend 61, and a book-topping column 62 is slidably provided inside the guide bend 61. A limit head 63 is fixedly provided at the bottom of the book-topping column 62, and a tensioning band 64 is fixedly provided below the limit head 63. A circular hole 66 is opened on the side wall of the guide bend 61, and a pull wire 65 is passed through the circular hole 66. The top end of the pull wire 65 is fixedly connected to the limit head 63, and a conical blocking head 67 is fixedly provided on the pull wire 65. The extension column 201 first pushes the bottommost book. First, the book is pushed to the bottom of the pressure plate 19, which smooths the pages and prevents them from wrinkling due to friction. When the extension column 201 pushes the book into the inlet 14, the magnetic plate 27 pulls the pull cord 65. After the pull cord 65 is pulled out, it is blocked by the blocking head 67, which pulls out the top book column 62, causing it to extend into the guide bend 61. The guide bend 61 lifts the second book, and as the extension column 201 slides in the same direction, the pressure of the second book on the first book is reduced, thus reducing the wrinkling of the pages. The pull cord 65 is elastic. Finally, the tension band 64 pulls the top book column 62 back to its original position.
