Description

Technical Field

[0001] The utility model belongs to the technical field of automatic book borrowing equipment, and particularly relates to a book feeding mechanism in a book borrowing and returning machine. Background Art

[0002] Indeed, the national reading trend in recent years shows that although the public's enthusiasm for reading remains undiminished, the actual reading volume has not increased significantly accordingly. Behind this phenomenon is the contradiction between the uneven distribution of library resources and the operating pressure of small bookstores - although large libraries have a rich collection of books, their locations are concentrated, which brings inconvenience to readers' borrowing; while small bookstores are difficult to maintain due to high operating costs, reducing the public's access to books.

[0003] To alleviate this situation, book borrowing and returning machines have emerged. They not only simplify the borrowing process, reduce operating costs, but also can be widely distributed to improve the accessibility of book services. However, the design of existing book borrowing and returning machines is relatively cumbersome, especially the book feeding mechanism, which needs to rely on complex structures to complete the transportation of books. For example, the utility model patent with the patent number 202322668303.8 needs to set up a baffle component that occupies a large space to adjust the position of books on the book feeding plate, and the book borrowing and returning process is complex.

[0004] In view of this, the present utility model is proposed. Content of the Utility Model

Specific embodiments

[0024] The following further describes the present invention in conjunction with specific embodiments.

[0025] In the following description, all concepts related to directions (or orientations) such as up, down, left, right, front, and back are with respect to the position state of the figure being described, aiming to facilitate public understanding, and thus should not be construed as a special limitation on the technical solution provided by the present invention.

[0026] As Figures 1-5 shown, a book delivery mechanism in a book borrowing and returning machine includes a U-shaped frame 1 and an upper cover body 2. A book transfer assembly, a book blocking assembly, and a book supporting assembly are provided inside the U-shaped frame 1. The book transfer assembly is arranged at the middle position inside the U-shaped frame 1 (the book transfer assembly is generally not arranged exactly in the middle of the U-shaped frame 1 and can be offset to the right a little to facilitate the book delivery plate 5 to correspond to the notch of the storage grid in the book borrowing machine when inserted into the storage grid). It is used to move the book delivery plate 5 back and forth inside the U-shaped frame 1. The book blocking assembly includes a first book blocking assembly and a second book blocking assembly. The first book blocking assembly is arranged at the rear end of the U-shaped frame 1, and the second book blocking assembly is arranged at the front middle end of the U-shaped frame 1. Both the first book blocking assembly and the second book blocking assembly are used to limit the movement of the books on the book delivery plate 5. The book supporting assembly is arranged at the front end of the U-shaped frame 1 and is used to hold up the drooping book corners on both sides of the book.

[0027] The book transfer assembly includes a driving member 3 and a sliding member 4. The driving member 3 includes a driving motor 31. A motor runner 32 is provided on the driving motor 31, and a belt 33 is provided on the motor runner 32. The sliding member 4 includes a linear slide rail 41 and a slider 42. The slider 42 is connected to the belt 33, and the motor runner 32 drives the belt 33 to rotate, and at the same time drives the slider 42 to slide on the linear slide rail 41. The book delivery plate 5 is provided on the slider 42.

[0028] On both sides of the rear end of the U-shaped frame 1, there are first book-blocking components. Each first book-blocking component includes a first electromagnet 6. One end of the first electromagnet 6 is provided with a blocking piece 61. The first electromagnet 6 drives the blocking piece 61 to move up and down. The blocking piece 61 can block the movement of books. However, the book delivery plate 5 still moves backward, so that the books can be adjusted from the rear end of the book delivery plate 5 to the front end. Finally, the book delivery plate 5 moves forward again, carrying the books on the book delivery plate 5 to the pick-up and return opening of the borrowing and returning machine, facilitating readers to pick up books from the book delivery plate 5.

[0029] The book supporting component includes supporting plates 7 arranged on both sides of the front end of the U-shaped frame 1. Both the front and rear ends of the supporting plates 7 are provided with slopes 71 to facilitate the conveying of books. On both sides of the front middle part of the U-shaped frame 1, there are second book-blocking components. Each second book-blocking component includes a second electromagnet 8, and the top of the second electromagnet 8 penetrates through the supporting plate 7; similarly, the top of the second electromagnet 8 also restricts the movement of books. Then the book delivery plate 5 continues to move forward, so that the books can be adjusted from the front end of the book delivery plate 5 to the rear end. Finally, the book delivery plate 5 moves backward again, facilitating the books to be placed into the storage compartments.

[0030] On the upper cover body 2, there is a first measurement opening 21, which is arranged in cooperation with the barcode on the book, and the first measurement opening 21 is arranged in cooperation with the barcode scanner arranged inside the borrowing and returning machine. On the top of the upper cover body 2, there is a second measurement opening 22, which is arranged in cooperation with the book thickness measuring instrument arranged inside the borrowing and returning machine to measure the thickness of the books placed in the book delivery plate 5 and determine the storage compartment for placing the books. Inside the upper cover body 2, there is an RFID reader-writer. Inside the U-shaped frame 1, there is an induction switch, and the induction switch is electrically connected to the drive motor 31 (this is prior art, so it will not be elaborated).

[0031] The working principle is as follows:

[0032] When a reader needs to return a book, first place the book face down on the book delivery plate 5 through the pick-up and return opening on the borrowing and returning machine, so that the barcode of the book is exposed from the first measurement opening 21 on the upper cover body 2. Then, rotate the bracket through the servo motor or motor arranged on the inner side wall of the borrowing and returning machine, so that the barcode scanner on the bracket can be aligned with the barcode of the book to scan and confirm the book information; at the same time, confirm the height of the book through the book thickness measuring instrument and the second measurement opening 22, facilitating the book to be stored in the corresponding storage compartment inside the borrowing and returning machine. Or read the relevant information of the book through the RFID reader-writer arranged inside the upper cover body 2.

[0033] After confirming the book information, the drive motor 31 is driven to operate, that is, the motor runner 32 starts to rotate, the belt 33 starts to rotate, the slider 42 slides on the linear slide rail 41, and the slider 42 drives the book delivery plate 5 to be conveyed into the book borrowing and returning machine. When the book on the book delivery plate 5 moves past the second electromagnet 8, the book delivery plate 5 is conveyed in the reverse direction, that is, it moves away from the inside of the book borrowing machine. The second electromagnet 8 is energized, and the straight rod of the energized second electromagnet 8 will extend to block the book, so that the book can be blocked and adjusted from the front end of the book delivery plate 5 to the rear end. Then the second electromagnet 8 is de-energized, and the book delivery plate 5 continues to be conveyed into the book borrowing and returning machine. After the book on the book delivery plate 5 reaches the corresponding book storage grid position, since the book is at the rear end of the book delivery plate 5, the book can be easily inserted into the book storage grid. After inserting the book, the book delivery plate 5 is withdrawn, that is, the book return process is completed.

[0034] When a reader needs to borrow a book, relevant signals are sent to the drive motor 31. After the book delivery plate 5 is inserted into the book storage grid of the relevant book, the book is taken out onto the book delivery plate 5. Then the book delivery mechanism reaches the borrowing and returning opening position of the book borrowing and returning machine, and the first electromagnet 6 is energized. The straight rod of the energized first electromagnet 6 will extend, thereby driving the baffle 61 to rise to block the book. That is, the book delivery plate 5 moves into the book borrowing and returning machine through the drive motor 31, and the book delivery plate 5 moves backward, causing the book delivery plate 5 to move. However, due to the position limitation of the book, the book is blocked and adjusted from the rear end of the book delivery plate 5 to the front end. Then, the first electromagnet 6 is de-energized, the borrowing and returning opening door is opened, and the book delivery plate 5 moves in the reverse direction, that is, forward, until the book on the book delivery plate 5 is exposed at the borrowing and returning opening for the reader to pick up. When the book moves back and forth, the book will be supported by the support plate 7 at the two drooping book corners of the book to facilitate unobstructed movement. The whole process is simple and easy to implement.

[0035] The above content is a further detailed description of the provided technical solution in combination with the preferred implementation mode of this patent. It cannot be determined that the specific implementation of the present utility model is only limited to the above descriptions. For those of ordinary skill in the technical field to which this patent belongs, without departing from the concept of this patent, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of this patent.
