[0003] Chinese Patent with the publication number CN203407721U discloses an intelligent book access device, which includes a base and a bookshelf platform arranged on the base. A bookshelf is arranged on the bookshelf platform; on the base on the side of the bookshelf, a book storage mechanism is arranged, which cooperates with a book pushing mechanism to put books into the bookshelf, and on the base behind the bookshelf, a book retrieval conveyor mechanism is arranged, which cooperates with the book pushing mechanism to take books out of the bookshelf. In the present utility model, a book storage mechanism, a book retrieval mechanism, and a book pushing mechanism are arranged on the base below the bookshelf. The two cooperate with the book pushing mechanism to store books into the bookshelf or take books out of the bookshelf. Through the cooperation of horizontal and vertical linear motors, the situation that traditional book access needs to be manually completed is changed, and the device completely replaces manual work, solving a series of complicated processes in borrowing and returning books, improving work efficiency and reducing costs.

[0004] Although the above-mentioned intelligent book access device can meet the access of books, it cannot sort the books during the access of books, and there will be situations where the books are placed backwards, obliquely, and in a mess.

[0005] Chinese Patent with the publication number CN207172080U discloses an intelligent book sorting device for a library, which includes a frame, a robotic arm, a moving mechanism, a book identifier, a book box, and a control module circuit-connected to the robotic arm, the moving mechanism, and the book identifier. The robotic arm can move three-dimensionally in the three directions of the length, width, and height of the bookshelf to realize the book sorting operation within the range of the frame; and the robotic arm realizes the access and shelving of books during book sorting by rotating up and down around the X-axis through a rotating component; a rotating component is also arranged on the robotic arm for sorting books placed backwards or upside down. The present utility model provides an intelligent book sorting device that can sort various book placement problems, can sort books with incorrect placement positions, placed backwards, or upside down, can bear the book sorting burden for library administrators, and provide better reading services for readers.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The mobile rack moves up and down, and the mobile seat moves left and right on the mobile rack, enabling the gripper to move to the position for accessing books. The electric telescopic rod drives the movement of the gripper to access books, thus realizing the automatic access of books.

[0021] 2. Borrowers can perform book borrowing operations through a touch device. The books taken by the clamping mechanism are sent out through the book-taking window by the conveyor belt to complete book borrowing. The partition separates borrowers from the storage of books, preventing borrowers from damaging or polluting books when taking books by themselves. At the same time, it also avoids accidental injuries to borrowers when the access device is working.

[0022] 3. When the gripper on the clamping mechanism clamps a book, the driving gear on the reversing motor drives the reversing gear to rotate. The reversing gear drives the rotation of the electric telescopic rod, which in turn drives the rotation of the gripper to achieve the turning adjustment of the book. This can correct an inverted book. There is a placement seat for placing books on the conveyor belt, and the placement seat can be adjusted in terms of turning on the conveyor belt. When the gripper clamps a book, if the spine direction of the book is placed incorrectly, the spine side of the book can be corrected by adjusting the turning of the placement seat, so as to better meet the effective sorting during the automatic access of books, with better sorting ability, thus ensuring that the storage of books is more unified and regular.

[0023] 4. The gripper uses the clamping plates on the upper and lower clamping driving parts to clamp books. The adjustment motor drives the upper and lower adjustment lead screws to rotate. The rotation of the upper and lower adjustment lead screws drives the upper and lower clamping driving parts to move in opposite or relative directions, thereby realizing the adjustment of the clamping positions of the upper and lower clamping plates of the book, enabling better clamping and support during the access of books, effectively preventing the book from being wrinkled, deformed or bent, and thus better protecting the book during storage.

[0036] Such as Figure 1As shown in the figure, an intelligent access device for library books includes a bookshelf 1 for placing books. A movable rack 3 that moves up and down is arranged on the front side of the bookshelf 1. Guide rails 2 for the movable rack 3 to move up and down are fixed on both the left and right sides of the bookshelf 1. A clamping mechanism 4 for accessing books is installed on the movable rack 3. The clamping mechanism 4 moves left and right on the movable rack 3. A conveyor belt 5 extending to the right is arranged at the lower right corner near the front side of the bookshelf 1. By moving the movable rack 3 up and down and the clamping mechanism 4 moving on the movable rack 3, the books on the bookshelf 1 are grabbed and placed on the conveyor belt 5 for book transportation. At the same time, the returned books are sent to the bookshelf 1 through the conveyor belt 5, and the clamping mechanism 4 is used to clamp and place the books on the bookshelf 1, thus realizing the automatic access of books. A partition 7 is arranged on the right side of the bookshelf 1. The right end of the conveyor belt 5 passes through the partition 7. A book-taking window 8 is opened at the position where the partition 7 is located through which the conveyor belt 5 passes. A touch control device 9 is fixed at a position near the book-taking window 8 on the side of the partition 7 away from the bookshelf 1. Borrowers can perform book borrowing operations through the touch control device 9, and the books taken by the clamping mechanism 4 are sent out through the book-taking window 8 through the conveyor belt 5 to realize book borrowing. The partition 7 separates the borrowers from the storage of books, avoiding damage or pollution to the books caused by borrowers taking books by themselves, and also avoiding accidental injuries to borrowers when the access device is working.

[0037] The touch control device 9 is provided with a touch screen and control buttons for borrowers to operate during borrowing and returning books. At the same time, the touch control device 9 is provided with a camera that can perform face recognition and information collection on borrowers, facilitating information collection and statistics during book borrowing.

[0038] As Figure 1 and Figure 2As shown in the figure, the clamping mechanism 4 includes a moving seat 43 that moves left and right on the moving frame 3. On one side of the moving seat 43 facing the bookshelf 1, there are clamping jaws 44 for clamping books. On the other side of the moving seat 43, there is an electric telescopic rod 41 installed to drive the clamping jaws 44 to move back and forth in the direction of the bookshelf 1. On the side of the clamping jaws 44 facing the bookshelf 1, there is a vision camera 45 installed. The vision camera 45 is used to collect images of the books, so as to judge whether the books are in a proper position and identify whether the access of the books is accurate. The up and down movement of the moving frame 3 and the left and right movement of the moving seat 43 on the moving frame 3 enable the clamping jaws 44 to move to the position for accessing the books, and the electric telescopic rod 41 is used to drive the movement of the clamping jaws 44 to access the books. The electric telescopic rod 41 is rotatably installed on the moving seat 43, and a reversing gear 46 is sleeved on the outside of the electric telescopic rod 41. A reversing motor 42 is fixed on the moving seat 43, and a driving gear meshing with the reversing gear 46 is fixed on the output shaft of the reversing motor 42. When the clamping jaws 44 clamp the books, the driving gear on the reversing motor 42 drives the reversing gear 46 to rotate, and the reversing gear 46 drives the rotation of the electric telescopic rod 41, thereby driving the rotation of the clamping jaws 44 for the books, so as to realize the steering adjustment of the books and be able to correct the inverted books. A placement seat 6 for placing books is installed on the conveyor belt 5, and the placement seat 6 can be adjusted for steering on the conveyor belt 5. When the clamping jaws 44 clamp the books, if the spine direction of the book is placed in the wrong direction, the spine side of the book can be corrected by adjusting the steering of the placement seat 6, so as to better meet the effective sorting during the automatic access of the books, have better sorting ability, and ensure that the storage of the books is more unified and regular.

[0039] As Figure 3 shown, the clamping jaws 44 include an adjustment mechanism 441 fixedly connected to the top rod of the electric telescopic rod 41. On one side of the adjustment mechanism 441 facing the bookshelf 1, there are two upper and lower clamping driving members 442 that can be adjusted to move up and down. On one side of the clamping driving members 442 facing the bookshelf 1, there are two left and right clamping plates 443, and the clamping driving members 442 drive the two left and right clamping plates 443 to move in opposite directions or in opposite directions. The clamping jaws 44 use the clamping plates 443 on the two upper and lower clamping driving members 442 to clamp the books, and the adjustment of the clamping driving members 442 on the upper and lower sides through the adjustment mechanism 441 realizes the adjustment of the clamping position of the books, so as to better realize the clamping of the books during storage.

[0040] As Figure 4As shown in the figure, the adjusting mechanism 441 includes a vertically arranged guiding column 4414. A connecting seat 4411 is fixed to the front side of the guiding column 4414. Adjusting screws 4413 are arranged on both the upper and lower sides of the connecting seat 4411. An adjusting motor 4412 for driving the adjusting screws 4413 on both the upper and lower sides to rotate is installed inside the connecting seat 4411. The thread directions of the adjusting screws 4413 on both the upper and lower sides are opposite. When the adjusting motor 4412 drives the adjusting screws 4413 on both the upper and lower sides to rotate, the clamping driving members 442 on both the upper and lower sides move relatively or in opposite directions, thereby realizing the adjustment of the clamping positions of the upper and lower clamping plates 443 for the book, enabling better clamping and support when storing and retrieving the book, effectively preventing the book from being wrinkled and bent, and thus better protecting the book during storage.

[0041] As Figure 5 shown in the figure, the clamping driving member 442 includes a horizontally arranged support seat 4425. One end of the clamping plate 443 is slidably clamped on the support seat 4425. Fixed plates 4424 are fixed to both ends of the support seat 4425. A bidirectional screw 4426 whose thread penetrates through both clamping plates 443 is arranged between the two fixed plates 4424 on both sides. A clamping motor 4423 for driving the bidirectional screw 4426 to rotate is fixed to one side of one of the fixed plates 4424. When clamping the book during storage and retrieval, the clamping motor 4423 drives the bidirectional screw 4426 to rotate, and the rotating bidirectional screw 4426 drives the clamping plates 443 on both the left and right sides to move relatively, thereby clamping the book and realizing the clamping of the book.

[0042] A driving block 4421 is fixed to the side of the support seat 4425 away from the clamping plate 443. A socket 4422 sleeved on the guiding column 4414 is formed on the driving block 4421. The adjusting screw 4413 threadedly penetrates through the driving block 4421. The driving block 4421 moves up and down by sleeving the socket 4422 on the guiding column 4414, and the driving block 4421 is driven to move in the up and down directions by the adjusting screw 4413.

[0043] As Figure 6 shown in the figure, a plurality of placement cavities 61 for placing books are formed inside the placement seat 6. An installation plate 63 fixed to the conveyor belt of the conveyor belt 5 is arranged on the lower side of the placement seat 6. The installation plate 63 is fixed to the conveyor belt 5, and the placement seat 6 is installed by using the installation plate 63, thereby realizing the installation of the placement seat 6 on the conveyor belt 5, and enabling the conveyor belt 5 to convey the placement seat 6.

[0044] A rotating shaft 62 passing through the mounting plate 63 is fixed to the lower end surface of the placement seat 6. A rotating mechanism 64 for driving the rotation of the rotating shaft 62 is fixed to the lower side of the mounting plate 63. The placement seat 6 is rotatably mounted on the mounting plate 63 by means of the rotating shaft 62. At this time, the rotating mechanism 64 drives the rotating shaft 62 to drive the placement seat 6 to rotate, thereby adjusting the direction of the books in the placement seat 6.

[0045] As Figure 7 shown, the rotating mechanism 64 includes a rotating motor 641 fixed to the lower side of the mounting plate 63 and a rotating gear 642 fixed to the rotating shaft 62. A driving gear 643 meshing with the rotating gear 642 is fixed to the output shaft of the rotating motor 641. The rotating motor 641 drives the driving gear 643 to rotate, and the driving gear 643 drives the rotating gear 642 to drive the rotating shaft 62 to rotate, thereby realizing the driving of the entire placement seat 6 to rotate.

[0046] As Figure 8 shown, the conveyor belt 5 includes a support frame 51 on the lower side. Two front and rear reinforcing plates 52 are fixed to the lower side of the support frame 51. The support frame 51 cooperates with the reinforcing plates 52 to support the entire conveyor belt 5.

[0047] Two connecting plates 54 perpendicular to and passing through the two reinforcing plates 52 are provided on the lower side of the support frame 51. A first tightening screw 53 that abuts against the lower side of the support frame 51 is screwed on the portion of the connecting plate 54 located between the two reinforcing plates 52. The connecting plate 54 passes through the two reinforcing plates 52 to achieve connection and cooperation with the support frame 51, and is locked and fixed by the tightening of the first tightening screw 53 when the connecting plate 54 and the support frame 51 are connected.

[0048] One end of the connecting plate 54 away from the support frame 51 is provided with a mounting sleeve 56 fixed to the bottom of the bookshelf 1. The connecting plate 54 passes through the mounting sleeve 56. A second tightening screw 55 that abuts against the connecting plate 54 is threadedly mounted at the bottom of the mounting sleeve 56. The mounting sleeve 56 is fixed to the bottom of the bookshelf 1. The connecting plate 54 is inserted into the mounting sleeve 56 and is locked and fixed by screwing the second tightening screw 55 to abut against the connecting plate 54, thereby completing the fixed connection between the connecting plate 54 and the conveyor belt 5 and the bookshelf 1.

[0049] As Figure 9 shown, the guide rail 2 includes a T-shaped plate 21 fixed to the side of the bookshelf 1. A rack 22 is fixed to one side of the T-shaped plate 21. The T-shaped plate 21 guides the up and down movement of the moving rack 3 and realizes the walking drive cooperation with the moving rack 3 during movement through the rack 22.

[0050] As Figure 10As shown in the figure, the moving frame 3 includes moving support plates 32 on both the left and right sides. A card slot 37 for clamping on the T-shaped plate 21 is provided on one side of the moving support plate 32. A traveling gear 31 meshing with the rack 22 is installed on one side of the moving support plate 32. A traveling motor 36 for driving the rotation of the traveling gear 31 is fixed on the other side of the moving support plate 32. The moving support plate 32 is clamped on the T-shaped plate 21 through the card slot 37 for moving guidance. At this time, the traveling motor 36 drives the traveling gear 31 to rotate, and the rotating traveling gear 31 cooperates with the rack 22 to perform up and down walking, so as to realize the up and down movement of the entire moving frame 3 on the bookshelf 1;

[0051] A driving lead screw 34 with a thread passing through the moving seat 43 and a guide rod 33 passing through the moving seat 43 are respectively arranged between the moving support plates 32 on both the left and right sides. A driving motor 35 for driving the rotation of the driving lead screw 34 is fixed on one of the moving support plates 32. The guide rod 33 guides the moving seat 43 during left and right movement. The driving motor 35 drives the driving lead screw 34 to rotate, and the rotating driving lead screw 34 drives the moving seat 43 to move in the left and right directions, so as to realize the movement of the moving seat 43 on the moving frame 3.

[0052] As Figure 11 shown in the figure, a bottom plate 110 is fixed at the lower end of the bookshelf 1. Roller legs 120 are fixed on the lower surface of the bottom plate 110 near the four corners. The bookshelf 1 is convenient for moving and adjusting the position of the bookshelf 1 through the roller legs 120 arranged at the bottom;

[0053] Electric lifting rods 140 are fixed at both the left and right ends of the bottom plate 110. A backing plate 130 is fixed at the lower end of the top rod of the electric lifting rod 140. After the position adjustment of the bookshelf 1 is completed, the top rod of the electric lifting rod 140 extends downward so that the backing plate 130 touches the ground for support, thereby fixing the position of the bookshelf 1.

[0054] Working principle: When borrowing books, the borrower performs face recognition and information collection through the camera on the touch device 9. The borrower performs borrowing operations through the touch screen and selects the books to be borrowed. At this time, the touch device 9 controls the up and down movement of the moving frame 3. At the same time, the left and right movement adjustment of the moving seat 43 on the moving frame 3 enables the clamping mechanism 4 to move to the corresponding book position. At this time, image collection and authentication are performed through the vision camera 45. After determining the book, the electric telescopic rod 41 drives the movement of the clamping jaws 44 to clamp the book and place the clamped book inside the placing seat 6. At this time, the conveyor belt 5 works to move the placing seat 6 with the book through the book-taking window 8 to the outside. At this time, the borrower can take the book;

[0055] When the borrower returns the book, the book is placed inside the placement seat 6. At this time, the conveyor belt 5 sends the placement seat 6 with the book to the bookshelf 1. At this time, with the cooperation of the moving frame 3 and the moving seat 43, the clamping mechanism 4 moves to the placement seat 6. At this time, the vision camera 45 on the clamping mechanism 4 collects images of the book and transmits the information to the touch device 9 to analyze whether the book is inverted and whether the spine direction is reversed. If the spine direction is reversed, at this time, the touch device 9 controls the rotation motor 641 to drive the driving gear 643 to rotate, and the driving gear 643 drives the rotating gear 642 to drive the rotating shaft 62 to rotate, so as to drive the rotation of the entire placement seat 6 to correct the spine direction. After the spine direction is corrected, the electric telescopic rod 41 drives the movement of the clamping jaws 44 to clamp the book. If the book is in an inverted state, the touch device 9 continues to control the reversing motor 42 to work, so that the driving gear drives the reversing gear 46 to rotate, and the reversing gear 46 drives the rotation of the electric telescopic rod 41 to drive the clamping jaws 44 to rotate the book, so as to correct the inverted book, and place the book on the bookshelf 1 with the cooperation of the moving frame 3, the moving seat 43, the electric telescopic rod 41 and the clamping jaws 44.

[0056] The above is the preferred embodiment of the present invention. Those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiment. Therefore, the present invention is not limited to the above specific embodiments, and any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present invention all belong to the protection scope of the present invention.
