DETAILED DESCRIPTION
[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0035] Embodiment 1: Reference Figures 1-3 The automatic arrangement device for returning books in a library shown in the figure includes a carrying rack 1 and two groups of storage frames 2 arranged from top to bottom inside the carrying rack 1, each group of storage frames 2 is equidistantly distributed along a circular track, and each group of storage frames 2 is provided below with a driving unit capable of controlling the synchronous movement of the group of storage frames 2 out of or into the inside of the carrying rack 1.
[0036] In the use process of the automatic arrangement device for returning books in a library, different storage frames 2 can store different types of books. When returning books, the two groups of storage frames 2 are moved out synchronously, and the book borrower can place the books into the designated storage frame 2 according to the type of the books. Therefore, in the present application, the storage frame 2 moved out of the carrying rack 1 can facilitate the returning and arranging operation of the books, has the effect of centralized storage of the books, and reduces the workload of book stacking and manual arrangement.
[0037] Subsequently, the storage frame 2 storing books is moved into the inside of the carrying frame 1, and a large number of returned books are stored in the inside of the carrying frame 1. When the books stored in the inside of the upper and lower groups of storage frames 2 reach a specified number, the movable carrying frame 1 is moved so that the carrying frame 1 reaches different bookshelf positions in the library, and the returning operation of the books is performed. Before the process of performing the book returning operation, the storage frame 2 loaded with books is synchronously moved out, so that the library staff can take out the books in the inside of the storage frame 2. In the process of returning the books, the borrower can refer to the types of books placed in the storage frame 2 or the identification of the storage frame 2 to return the books to the appropriate storage frame 2, so that the staff can concentrate the books of different types. This operation improves the efficiency of returning, sorting and returning a large number of books, and saves human resources.
[0038] In addition, in the process of storing books and concentrating and carrying returned books, the storage frame 2 is moved into the inside of the carrying frame 1, so that the books are protected, the books are effectively prevented from being eroded and damaged by the external environment, and the safety of the books is ensured.
[0039] Further, in the present application, the inside of the storage frame 2 is provided with symmetrically distributed limiting side plate one 4 and limiting side plate two 5, and a plurality of parallel arranged partitions 3 are arranged between the limiting side plate one 4 and the limiting side plate two 5. In the process of returning the books, the books need to be laid in the gap between the two partitions 3, and the limiting side plate one 4 and the limiting side plate two 5 are located on both sides of the books. The arrangement of the plurality of partitions 3 can prevent the books stacked to a certain height from sliding and collapsing in the inside of the storage frame 2.
[0040] When the storage frame 2 is moved into the inside of the carrying frame 1, the carrying frame 1 performs the operation of concentrating and storing the books, or the carrying frame 1 carries a large number of storage frames 2 to move synchronously, with the movement of the storage frame 2, the limiting side plate one 4 and the limiting side plate two 5 move and abut on both sides of the books, which has a limiting effect on the books. In the process of moving the storage frame 2 out of the inside of the carrying frame 1, the borrower puts the books into the inside of the storage frame 2, or the staff takes out the books in the inside of the storage frame 2 for returning, with the movement of the storage frame 2, the limiting side plate one 4 and the limiting side plate two 5 move away from the books, which reduces the resistance in the process of putting in and taking out the books, and further avoids damaging the books.
[0041] As shown in Figures 4-6 The back of the storage frame 2 is fixed with two limiting tables 21, the bottom ends of the two limiting tables 21 are respectively fixed with a linkage rack 22 and a linkage slide 23, the inside of the carrying frame 1 is fixed with two positioning rings 17 located below the two groups of storage frames 2, the positioning ring 17 is fixed with a plurality of limiting guide rails one 171 equidistantly distributed along the circumferential track, and the linkage rack 22 and the linkage slide 23 are slidably connected with the limiting guide rails one 171.
[0042] Therefore, when the linkage rack 22 and the linkage slide 23 move along the distribution direction of the limiting guide rail one 171, the arrangement of the limiting guide rail one 171 can keep the stability of the linkage rack 22 and the linkage slide 23 when moving. And the limiting platform 21 moves synchronously with the storage frame 2, so as to drive the storage frame 2 to move out or into the inside of the carrying frame 1.
[0043] As shown in Figures 4-6 The driving unit comprises a driving gear ring 11 installed in the carrying frame 1, and the inside of the driving gear ring 11 is provided with a motor gear 12 for driving the rotation of the driving gear ring 11. A plurality of first linkage gears 13 are meshed and connected to the inside of the driving gear ring 11, and a second linkage gear 14 which can rotate synchronously with the first linkage gear 13 is installed above the first linkage gear 13 through a linkage shaft 15. The second linkage gear 14 is meshed and connected with a plurality of linkage racks 22.
[0044] When the two motor gears 12 distributed from top to bottom simultaneously drive the rotation of the driving gear ring 11, with the rotation of the driving gear ring 11, a plurality of groups of first linkage gears 13, linkage shafts 15 and second linkage gears 14 rotate synchronously to achieve the purpose of driving a plurality of groups of linkage racks 22, linkage slides 23 and limiting platforms 21 to move synchronously, thereby enabling the two groups of limiting frames distributed from top to bottom to move out or into the inside of the carrying frame 1 synchronously.
[0045] As shown in Figures 5-7 The top end of the linkage shaft 15 is provided with a synchronous gear 16, and the bottom end of the storage frame 2 is provided with a passage for accommodating the linkage shaft 15 and the synchronous gear 16. The bottom end of the limiting side plate one 4 and the limiting side plate two 5 is respectively provided with a guide frame one 41 and a guide frame two 51. In order not to affect the operation of placing and taking out the books, in the present application, the guide frame one 41 and the guide frame two 51 are located below the partition plate 3, and the guide frame one 41 and the guide frame two 51 are in L-shaped structure distribution.
[0046] The longer frame body of the guide frame one 41 and the guide frame two 51 is meshed and connected with the synchronous gear 16 through a rack, and the guide frame one 41 and the guide frame two 51 are located at the front and rear sides of the synchronous gear 16 respectively. When a plurality of groups of first linkage gears 13, linkage shafts 15 and second linkage gears 14 rotate synchronously under the meshing action of the driving gear ring 11, the synchronous gear 16 can rotate. With the rotation of the synchronous gear 16, the guide frame one 41 and the guide frame two 51 move towards the opposite or the same direction respectively, so as to drive the limiting side plate one 4 and the limiting side plate two 5 to move towards the opposite or the same direction synchronously.
[0047] Specifically, when the storage frame moves out of the outside of the carrying frame 1, the limiting side plate one 4 and the limiting side plate two 5 move in opposite directions to provide sufficient space for the insertion and removal of books, avoid squeezing or damaging the books, and facilitate the operation of the book borrowers and the staff. When the storage frame 2 moves into the inside of the carrying frame 1, the limiting side plate one 4 and the limiting side plate two 5 move in opposite directions and tightly adhere to the two sides of the books, which plays a good limiting and fixing role on the books, prevents the books from sliding due to shaking during the carrying process, and effectively ensures the safety of the books during the centralized storage and transfer process. In the present application, the relative position state of the limiting side plate one 4 and the limiting side plate two 5 can be automatically adjusted with the movement state of the storage frame 2. This greatly improves the efficiency and convenience of the library book return, arrangement and homing work, and also better protects the books.
[0048] As Figure 6 , Figure 7 shown, in the present application, in order to maintain the stability of the guide frame one 41 and the guide frame two 51, two sets of supporting tables 18 are fixed inside the carrying frame 1, below the two sets of storage frames 2, the linkage shafts 15 are all rotationally installed with the supporting tables 18, the synchronous gears 16, the guide frame one 41 and the guide frame two 51 are all located above the supporting tables 18, and two sets of limiting guide rails two 181 are fixed on the supporting tables 18, which are matched with the guide frame one 41 and the guide frame two 51 respectively. With the rotation of the synchronous gears 16, the guide frame one 41 and the guide frame two 51 move smoothly along the trajectory of the limiting guide rails two 181, so as to improve the stability during the movement of the limiting side plate one 4 and the limiting side plate two 5.
[0049] As Figures 8-10 shown, in the present application, the inside of the storage frame 2 is provided with vertically distributed guide rods 24, the upper and lower ends of the guide rods 24 extend in the horizontal direction to form bosses, and the multiple partitions 3 located inside the same storage frame 2 are all connected with the guide rods 24 in a sliding manner. The spacing between the multiple partitions 3 can be adjusted.
[0050] In the present application, the inside of the storage frame 2 is provided with a gas cylinder 6, the output end of the gas cylinder 6 is connected with the uppermost partition 3, the lowermost partition 3 is connected with the boss at the lower end of the guide rod 24, and the adjacent partitions 3 are all connected through an elastic variable pitch structure. Therefore, the lowermost partition 3 is always in a stable state.
[0051] The cylinder 6 can accurately control the position of the uppermost partition plate 3 according to the actual situation. During the process of putting in and taking out books, the cylinder 6 drives the uppermost partition plate 3 to move upwards, providing sufficient moving space for the lower partition plate 3, so as to expand the spacing of the partition plate 3 for the purpose of putting in and taking out books, effectively avoiding the phenomenon of friction damage of books. During the process of storing books, the cylinder 6 can drive the uppermost partition plate 3 to move downwards, so that the books are more compactly stacked inside the partition plate 3, avoiding the phenomenon of shaking of the books during storage and concentrated transportation. This adjustable spacing design can adapt to the operation needs of the user, further improving the practicality and flexibility of the equipment.
[0052] Specifically, as shown in Figure 10 The elastic variable spacing structure includes a connecting rod 7 penetrating through the two partition plates 3 distributed from top to bottom, a sliding sleeve 8 is sleeved on the connecting rod 7, and a positioning sleeve 10 is fixed to the bottom end of the connecting rod 7. The sliding sleeve 8 is connected with the positioning sleeve 10 through the reset spring 9.
[0053] The sliding sleeve 8 is fixed with the upper partition plate 3, and the positioning sleeve 10 is fixed with the lower partition plate 3. During the process of storing books, the cylinder 6 controls the uppermost partition plate 3 to descend, and when the uppermost partition plate 3 descends to a certain distance, the sliding sleeve 8 fixed with the partition plate 3 descends, the reset spring 9 contracts, and the positioning sleeve 10, the partition plate 3 fixed with the positioning sleeve 10 and the connecting rod 7 descend synchronously, so as to drive the multiple partition plates 3 to reduce the spacing and compact the books. During the process of putting in and taking out books, the cylinder 6 drives the uppermost partition plate 3 to move upwards, and under the elastic potential energy of the reset spring 9, the multiple partition plates 3 can quickly reset, so as to drive the multiple partition plates 3 to expand the spacing.
[0054] This elastic variable spacing structure makes the spacing adjustment between the partition plates 3 more stable and smooth. When the cylinder 6 drives or pulls the partition plate 3 to move, the reset spring 9 can play a buffering and stabilizing role, avoiding the partition plate 3 from moving too fast or shaking, and ensuring the safety and stability of the books.
[0055] As shown in Figure 1 The carrying rack 1 is provided with a plurality of equidistantly distributed supporting legs 19, the bottom end of each supporting leg 19 is provided with a universal wheel, and the upper end of each supporting leg 19 is fixed with a handle. When it is necessary to move the carrying rack 1 loaded with a large number of returned books to different bookshelf positions in the library for book returning operation, the staff only needs to hold the handle and easily move the carrying rack 1 through the flexible rotation of the universal wheel, greatly saving manpower and improving work efficiency. Moreover, the design of the universal wheel enables the carrying rack 1 to flexibly turn in a small space, adapt to the complex environment in the library, and conveniently and quickly transport the books to the specified position.
[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
