Description

Technical Field

[0001] This utility model relates to the technical field of self-service machines, specifically to a library self-service machine. Background Technology

[0002] Self-service book machines are generally automatic book return machines and are an important part of library automation services. Their main function is to facilitate readers to quickly and independently return borrowed books and other materials, while improving the efficiency of library operations.

[0003] Self-service book vending machines are divided into indoor and outdoor types. Indoor vending machines generally consist of the machine itself and a book box. To reduce costs, these two components are usually separate. After returning a book on the machine, the book can be placed in the book box. Outdoor vending machines require controllable book boxes to prevent passersby from taking books.

[0004] Chinese patent application CN201621178098.0, entitled "A Self-Service Book Borrowing and Returning Machine," discloses a self-service book borrowing and returning machine. After a book is placed in the return slot, it is smoothly placed onto a shelf or onto existing books on the shelf. A lifting motor drives a telescopic rod to descend smoothly, ensuring the book is placed flat and prevents it from falling or being crushed. However, this patent has the following shortcomings: when library staff retrieve books, they need to manually remove the books from the shelf one by one, affecting the efficiency of book repositioning. Furthermore, different books have different shapes, and there is a risk of them tipping over when stacked vertically, causing books to scatter inside the machine. Therefore, a self-service library machine is needed. Utility Model Content

[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problems in the prior art where it is time-consuming to manually remove the books from the book return machine and the books will scatter inside the machine when it is tilted.

[0006] To achieve the above objectives, this utility model provides a library self-service machine, comprising: a shell with an openable door on the back, a three-axis moving unit assembled inside the shell, a bracket assembled on the moving end of the three-axis moving unit via an installation unit, and a book box with an open top located inside the shell.

[0007] The top of the outer shell is provided with a first window, and the first window is provided with an openable cover plate. The bracket includes a connecting arm and a number of support rods that are spaced apart along the length direction of the connecting arm and are all fixedly connected to the connecting arm. The length direction of the support rods is perpendicular to the length direction of the connecting arm. The side wall of the book box near the three-axis moving unit is provided with a number of top-opening strip grooves for the support rods to be inserted. The part between two adjacent strip grooves on the book box is a book-keeping strip.

[0008] Preferably, the end of the support rod away from the connecting arm is inclined upward to form an inclined anti-fall part, and a limit plate is fixedly connected to the two outermost support rods, and the end of the support rod connected to the connecting arm is lower than the top of the connecting arm.

[0009] Preferably, the bottom of the outer shell is provided with a pair of corner positioning plates that match the book box, the outer wall of the book box away from the three-axis moving unit is equipped with a handle that can contact the door, and the bottom of the book box is equipped with several pulleys.

[0010] Preferably, a second window is provided on the side wall of the outer casing, which is close to the first window. A book receiving box is provided on the second window, which is located directly below the second window. The distance between the book receiving box and the first window is set to form a book receiving channel for the tray to enter.

[0011] Preferably, the mounting unit includes a horizontal mounting arm fixedly connected to the moving end of the three-axis moving unit, a rotating arm rotatably connected to the end of the mounting arm away from the moving end of the three-axis moving unit, and a horizontal first electric push rod mounted on the mounting arm via a hinge seat and drivenly connected to the rotating arm.

[0012] The length direction of the connecting arm is consistent with the length direction of the book box, the first window is offset from the book box, and the connecting arm and the rotating arm are fixedly connected in the same length direction.

[0013] Preferably, the end of the mounting arm away from the moving end of the three-axis moving unit is provided with a first extension arm that is close to the book box, one end of the rotating arm is provided with a second extension arm that is hinged to the end of the first extension arm through a first hinge shaft, and the other end of the rotating arm is provided with a third extension arm that can abut against the mounting arm.

[0014] A first connecting rod is hinged to the middle of the first extension arm, and a second connecting rod is hinged to the second extension arm. The end of the first connecting rod away from the first extension arm is hinged to the end of the second connecting rod away from the second extension arm via a second hinge shaft. The moving end of the first electric push rod is hinged to the second hinge shaft.

[0015] Preferably, the top of the book box, located inside the outer shell, is tilted upwards.

[0016] Preferably, the cover plate is horizontally slidably connected to the lower top surface of the housing, and the housing is equipped with a horizontal second electric push rod whose movable end is fixedly connected to the cover plate.

[0017] According to the above technical solution, the library self-service machine provided by this utility model has the following beneficial effects when in use:

[0018] Firstly, when managers retrieve books, they can simply pull the book box away and return the books to the bookshelf, improving work efficiency. Also, if the stacked books tip over, they will scatter inside the book box, without adding extra work for the managers.

[0019] Secondly, the support rod is inserted downward into the strip groove, and then the moving end of the three-axis moving unit moves away from the book box along the Y-axis. The book-blocking strip will intercept the book, and the support rod will be pulled out from the strip groove, so the book falls into the book box. This allows several books to be stacked vertically in sequence, which can protect the books and prevent them from being directly smashed into the book box and causing damage. It can also increase the actual maximum capacity of the book box.

[0020] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0030] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0031] like Figure 1-5 As shown, a library self-service machine includes: a shell 2 with an openable door 1 on the back, a three-axis moving unit 3 assembled inside the shell 2, a bracket 4 assembled on the moving end of the three-axis moving unit 3 via an installation unit, and a book box 5 with an open top located inside the shell 2.

[0032] The top of the outer shell 2 is provided with a first window, and the first window is provided with an openable cover plate 6. The bracket 4 includes a connecting arm 7 and a plurality of support rods 8 that are spaced apart along the length direction of the connecting arm 7 and are all fixedly connected to the connecting arm 7. The length direction of the support rods 8 is perpendicular to the length direction of the connecting arm 7. The side wall of the book box 5 near the three-axis moving unit 3 is provided with a plurality of top-opening strip grooves for the support rods 8 to be inserted. The part between two adjacent strip grooves on the book box 5 is a book-blocking strip 9.

[0033] In the above technical solution, the moving end of the three-axis moving unit 3 can move in three directions. The horizontal direction of the arrangement of several strip grooves is the X-axis direction, the horizontal direction perpendicular to the X-axis direction is the Y-axis direction, and the vertical direction is the Z-axis direction. The structure and principle of the three-axis moving unit 3 are existing mature technologies, so they will not be elaborated on in this paper.

[0034] After the self-service machine confirms the return of the book, the cover 6 opens, and the book is placed on the tray 4. The moving end of the three-axis moving unit 3 first moves the tray 4 along the X-axis, so that the support rod 8 moves to the corresponding slot. Then, it moves the tray 4 vertically downward, so that the support rod 8 is inserted into the slot. Then, the moving end of the three-axis moving unit 3 moves away from the book box 5 along the Y-axis. The book blocking strip 9 will intercept the book, and the support rod 8 will be pulled out from the slot. The book will fall into the book box 5. This allows several books to be stacked vertically, which can protect the books and prevent them from being directly thrown into the book box 5 and causing damage. It can also increase the actual maximum capacity of the book box 5.

[0035] When managers retrieve books, they can simply pull book box 5 away and return the books to the bookshelf, improving work efficiency. Furthermore, if stacked books tip over, they will scatter inside book box 5, without adding extra work for the managers.

[0036] Because the bracket 4 can be moved vertically to adjust its height, the height at which the book falls can be adjusted. A smaller falling height is more conducive to stacking several books.

[0037] In a preferred embodiment of the present invention, the end of the support rod 8 away from the connecting arm 7 is inclined upward to form an inclined anti-fall part 10, and a limiting plate 11 is fixedly connected to the two outermost support rods 8. The end of the support rod 8 connected to the connecting arm 7 is lower than the top of the connecting arm 7.

[0038] In the above technical solution, the tops of the tilting anti-fall part 10, the limiting plate 11, and the connecting arm 7 are set higher than the support rod 8, which can prevent the book from falling during the movement of the bracket 4.

[0039] In a preferred embodiment of the present invention, the bottom of the outer shell 2 is provided with a pair of corner positioning plates 12 that match the book box 5, the outer wall of the book box 5 away from the three-axis moving unit 3 is equipped with a handle 13 that can contact the door body 1, and the bottom of the book box 5 is equipped with a number of pulleys.

[0040] In the above technical solution, the pulley facilitates the movement of the book box 5, the corner positioning plate 12 positions the book box 5, and the handle 13, while serving as a grip, can also contact the door 1 to limit movement, so that the book box 5 will not move inside the outer shell 2.

[0041] In a preferred embodiment of the present invention, a second window is provided on the side wall of the outer shell 2, which is close to the first window. A book receiving box 14 is provided on the second window, which is located directly below the second window. The distance between the book receiving box 14 and the first window is set to form a book receiving channel for the bracket 4 to enter.

[0042] In the above technical solution, because the spacing between the several support rods 8 is set, when the book is placed on the shelf 4, if the returner does not pay attention to make the book vertical, the book may fall between two adjacent support rods 8. Therefore, a book receiving box 14 is set up so that the fallen book will fall into the book receiving box 14. The returner can take the book out of the book receiving box 14 and put it back on the shelf 4 to avoid the problem of the book being unable to be returned after it falls.

[0043] In a preferred embodiment of the present invention, the mounting unit includes a horizontal mounting arm 15 fixedly connected to the moving end of the three-axis moving unit 3, a rotating arm 16 rotatably connected to the end of the mounting arm 15 away from the moving end of the three-axis moving unit 3, and a horizontal first electric push rod 17 mounted on the mounting arm 15 via a hinge seat and pulsatorically connected to the rotating arm 16.

[0044] The length direction of the connecting arm 7 is consistent with the length direction of the book box 5. The first window is offset from the book box 5. The connecting arm 7 and the rotating arm 16 are fixedly connected in the same length direction.

[0045] In the above technical solution, the first window is offset from the book box 5, which can increase the height of the book box 5 and thus increase the book capacity of the book box 5.

[0046] When returning a book, the book is placed on the holder 4. The first electric push rod 17 drives the rotating arm 16 to rotate 180° to change direction. Then, the book is returned under the drive of the three-axis moving unit 3. After the book is returned, the holder 4 moves back to the bottom of the first window to return to its original position.

[0047] In a preferred embodiment of this utility model, the end of the mounting arm 15 away from the moving end of the three-axis moving unit 3 is provided with a first extension arm 18 that is close to the book box 5. One end of the rotating arm 16 is provided with a second extension arm 19 that is hinged to the end of the first extension arm 18 through a first hinge shaft. The other end of the rotating arm 16 is provided with a third extension arm 20 that can abut against the mounting arm 15.

[0048] A first connecting rod 21 is hinged to the middle of the first extension arm 18, and a second connecting rod 22 is hinged to the second extension arm 19. The end of the first connecting rod 21 away from the first extension arm 18 is hinged to the end of the second connecting rod 22 away from the second extension arm 19 through a second hinge shaft. The moving end of the first electric push rod 17 is hinged to the second hinge shaft.

[0049] In the above technical solution, the first connecting rod 21, the second connecting rod 22, the first extension arm 18 and the second extension arm 19 form a four-bar linkage structure. Therefore, the first electric push rod 17 can push and pull the second hinge shaft to drive the rotating arm 16 to rotate 180°.

[0050] In a preferred embodiment of this utility model, the top of the book box 14 located inside the outer shell 2 is tilted upward.

[0051] In the above technical solution, when the book falls, it will slide out of the second window in the book receiving box 14 so that the person returning the book can take it and return it again.

[0052] In a preferred embodiment of this utility model, the cover plate 6 is horizontally slidably connected to the lower top surface of the outer shell 2, and the outer shell 2 is equipped with a horizontal second electric push rod whose movable end is fixedly connected to the cover plate 6.

[0053] In the above technical solution, the cover plate 6 can be slid by the second electric push rod to cover or open the first window.

[0054] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0056] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
