[0019] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0020] like Figure 1-13 As shown, a book sorting and conveying device includes: Suspended conveyor chain 1 is suspended on the top wall and slides along a preset track; Clamping mechanism 2, installed on the overhead conveyor chain 1, is used to transfer and transport books to be sorted; The sorting conveyor line 3 is connected downstream of the overhead conveyor chain 1 and includes a main conveyor line 30 and several branch conveyor lines 31. A driving mechanism 32 is provided between the main conveyor line 30 and the branch conveyor lines 31.

[0021] The suspended conveyor chain 1 is suspended on the top wall of the work site by the bracket 10 and slides along the extension direction of the preset track. The track can be flexibly planned according to the site layout without occupying ground space.

[0022] The clamping mechanism 2 is connected to the suspended conveyor chain 1 and moves synchronously with the suspended conveyor chain 1. Its clamping end is adapted to the size of the stack of books, which can achieve stable clamping.

[0023] The sorting conveyor line 3 is connected to the downstream area of ​​the overhead conveyor chain 1. The main conveyor line 30 is laid along the ground, and several branch conveyor lines 31 are distributed laterally on one side of the main conveyor line 30. The pushing mechanism 32 is installed at the junction of the main conveyor line 30 and each branch conveyor line 31 to push the books on the main conveyor line 30 to the corresponding branch conveyor line 31.

[0024] The suspended design completely solves the problem of large footprint and crowded space in traditional ground sorting lines, greatly improving the space utilization rate; the combination of the main conveyor line 30 and the branch conveyor line 31 realizes classified collection, and drives the mechanism 32 to accurately switch paths, adapting to the sorting needs of various types of books.

[0025] The actuation mechanism 32 can use a cylinder as the power element.

[0026] In some further embodiments, the track is hollow inside and has a clearance groove at the bottom. An opening 100 is provided at the top of one section of the track, and a drive belt 13 is provided at the position corresponding to the opening 100. The outer peripheral wall of the drive belt 13 is provided with first engaging teeth 130. The suspended conveyor chain 1 includes several horizontal chain links 4 and vertical chain links 5 that are hinged end to end and arranged in an alternating manner. The horizontal chain links 4 are provided with second engaging teeth 400 that cooperate with the first engaging teeth 130.

[0027] The track adopts a hollow structure design, forming an internal channel for the suspended conveyor chain 1 to slide. A clearance groove is opened along the length of the track to provide room for the connection between the clamping mechanism 2 and the suspended conveyor chain 1, thus avoiding interference.

[0028] An opening 100 is made above one section of the track, and a drive belt 13 is installed above the opening 100 via a bracket 10. The outer circumferential wall of the drive belt 13 is evenly provided with first engaging teeth 130. The suspended conveyor chain 1 is composed of several horizontal chain links 4 and vertical chain links 5 that are alternately hinged end to end. The horizontal chain links 4 are provided with corresponding second engaging teeth 400 that mesh with the first engaging teeth 130.

[0029] Power is transmitted through the meshing of the first clamping tooth 130 and the second clamping tooth 400, driving the suspended conveyor chain 1 to slide along the track to avoid slippage and ensure a uniform conveying speed of the clamping mechanism 2. The fit between the hollow track and the relief groove makes the structure compact and reduces motion interference.

[0030] For example, a motor 11 and a reducer are provided on the track. The motor 11 is belt driven with the reducer. The reducer drives the drive belt 13 to rotate. The drive belt 13 can be sleeved on the rotating wheel 12. The rotating wheel 12 is rotatably mounted in the bearing seat on the track through the shaft component.

[0031] In some further embodiments, the transverse link 4 includes two horizontal plates 40 spaced apart vertically, with a horizontal roller 41 rotatably connected to the inner wall of the track between the two horizontal plates 40, and a vertical shaft 42 between the two horizontal plates 40.

[0032] The vertical link 5 includes two vertical plates 50 spaced apart along the width of the track. A vertical roller is provided between the two vertical plates 50 and is rolledly connected to the upper and lower side walls of the track. A horizontal rotating shaft 51 is also provided between the two vertical plates 50. A rotating hole 52 is provided on the horizontal rotating shaft 51. The vertical rotating shaft 42 passes through the rotating hole 52 and rotates with the rotating hole 52.

[0033] The transverse link 4 consists of two horizontal plates 40 arranged parallel to each other at an interval. A horizontal roller 41 is rotatably mounted between the two horizontal plates 40 via a pivot. The horizontal roller 41 rolls in contact with the inner wall of the track, reducing the friction between the transverse link 4 and the track. A vertical pivot 42 is also fixed between the two horizontal plates 40 for connecting the vertical link 5.

[0034] The vertical rollers make rolling contact with the upper and lower side walls of the track, further reducing sliding resistance; the vertical shaft 42 of the transverse link 4 passes through the rotating hole 52 and forms a rotational fit, realizing the hinge between the transverse link 4 and the vertical link 5.

[0035] By combining horizontal rollers 41 and vertical rollers, friction loss between the suspended conveyor chain 1 and the track is reduced in all directions, improving smooth sliding and load-bearing capacity. At the same time, the articulated structure ensures that the conveyor chain can flexibly adapt to the turning of the track.

[0036] In some further embodiments, a sliding post 26 is vertically provided at the opening 100 of the track, a sliding shaft 27 is sleeved on the sliding post 26, a sliding roller 270 is rotatably provided on the sliding shaft 27, a limiting nut 261 is screwed on a section of the sliding post 26 that passes radially through the sliding shaft 27, a first spring 260 is provided between the limiting nut 261 and the sliding shaft 27, and the first spring 260 is sleeved on the sliding post 26; The sliding roller 270 elastically presses downward against the inner wall of the drive belt 13.

[0037] Sliding columns 26 are vertically fixed on both sides of the track corresponding to the opening 100. A sliding shaft 27 is sleeved on the sliding column 26 and can slide up and down along the sliding column 26. A sliding roller 270 is rotatably sleeved on the sliding shaft 27. The outer circumferential surface of the sliding roller 270 contacts the inner wall of the drive belt 13.

[0038] A limiting nut 261 is screwed onto a section of the sliding column 26 that radially passes through the sliding shaft 27. A first spring 260 is sleeved on the sliding column 26, with its two ends abutting against the bottom of the limiting nut 261 and the top of the sliding shaft 27, respectively, to form an elastic support.

[0039] The elastic force of the first spring 260 causes the sliding roller 270 to press down against the drive belt 13, ensuring that the drive belt 13 is tightly engaged with the transverse chain link 4, avoiding the disconnection of the locking teeth and thus preventing power interruption, thereby improving the stability and reliability of power transmission.

[0040] The limit nut 261 can adjust the compression of the first spring 260, thereby adjusting the resistance of the sliding roller 270 to adapt to different working conditions; the surface of the sliding roller 270 can be smoothed to reduce frictional loss with the drive belt 13.

[0041] In some further embodiments, the top of the clamping structure is provided with two spaced-apart rotating cavities 28. The upper opening of the rotating cavity 28 is 100 and a connecting cover plate 282 is movably provided. The connecting cover plate 282 is provided with a connecting hole. Two adjacent vertical chain links 5 are provided with rotating rods 281. The lower end of the rotating rod 281 passes through the connecting hole and is located in the rotating cavity 28. The lower end of the rotating rod 281 is provided with a limiting plate 283. The limiting plate 283 and the bottom of the rotating cavity 28 are provided with compression springs 280.

[0042] The clamping mechanism 2 has two spaced rotating cavities 28 on its top. The top of the rotating cavities 28 is open 100. A connecting cover plate 282 is movably installed. The connecting cover plate 282 is fixed by bolts for easy disassembly and maintenance. A connecting hole is provided on the connecting cover plate 282.

[0043] Rotating rods 281 are fixedly provided on two adjacent vertical chain links 5. The lower end of the rotating rods 281 passes through the connecting hole and extends into the rotating cavity 28. A limiting plate 283 is fixedly provided on the lower end of the rotating rods 281. The diameter of the limiting plate 283 is larger than the diameter of the connecting hole to prevent the rotating rods 281 from coming out.

[0044] A compression spring 280 is installed between the limiting plate 283 and the bottom of the rotating cavity 28.

[0045] The angle of the clamping mechanism 2 is adaptively adjusted by the cooperation of the rotating rod 281 and the rotating cavity 28. The compression spring 280 provides a certain damping for the rotation of the rotating rod 281 and the rotating cavity 28 to ensure the stability of the clamping mechanism 2 during transportation.

[0046] Two rotating rods 281 and two rotating cavities 28 are provided to ensure the stability of the clamping mechanism 2.

[0047] In this embodiment, the track is circular. The function of the rotating rod 281 and the rotating cavity 28 is to enable the entire clamping mechanism 2 to adapt to each other when going through a bend. That is, the rotating rod 281 rotates relative to the rotating cavity 28, so that the clamping mechanism 2 can go through a bend normally.

[0048] In some further embodiments, the clamping mechanism 2 includes two grippers 20, and the bottom of the grippers 20 is provided with a baffle 21; An elastic pressure plate 22 is provided above the area between the two grippers 20. A sliding rod 24 is provided above the elastic pressure plate 22. The sliding rod 24 passes through the sliding hole 25 on the clamping mechanism 2. An adjusting nut is screwed onto one end of the sliding rod 24 that passes through the sliding hole 25. A second spring 23 is sleeved on the sliding rod 24. The second spring 23 is located between the elastic pressure plate 22 and the sliding hole 25.

[0049] The clamping mechanism 2 includes two opposing grippers 20. A baffle 21 extends inward from the bottom of each gripper 20, supporting the bottom of the stack of books and preventing them from slipping off. An elastic pressure plate 22 is positioned above the area between the two grippers 20. A sliding rod 24 is fixedly connected above the elastic pressure plate 22. The sliding rod 24 passes through a sliding hole 25 at the top of the clamping mechanism 2 and can slide up and down along the sliding hole 25.

[0050] An adjusting nut is screwed onto one end of the sliding rod 24 that passes through the sliding hole 25. A second spring 23 is fitted onto the sliding rod 24. The second spring 23 is located between the upper surface of the elastic pressure plate 22 and the lower edge of the sliding hole 25.

[0051] The triple fixation of the stack of books is achieved through the gripper 20, the baffle 21, and the elastic pressure plate 22.

[0052] The pressure of the elastic pressure plate 22 can be adjusted by the adjusting nut to accommodate stacks of books of different thicknesses. This prevents books from falling due to excessively loose clamping, while also preventing damage from excessively tight clamping. The baffle 21 further enhances clamping reliability and adapts to changes in posture during the suspended transport process. The clamping mechanism 2 rotates via a motor 11 and a connecting rod, which is existing technology. Its power supply can be achieved through a sliding contact line on the track.

[0053] In some further embodiments, a visual recognition system is provided on the main conveyor line 30. The visual recognition system includes a camera and a mounting bracket. The camera is mounted on the mounting bracket and is located above the main conveyor line 30.

[0054] A visual recognition system is installed on the main conveyor line 30. The mounting frame is fixed to the side or top of the main conveyor line 30, and the camera is fixed on the mounting frame with the lens facing the conveying surface of the main conveyor line 30 and located directly above the conveyor belt to ensure that the cover or barcode area of ​​the book can be clearly photographed.

[0055] The visual recognition system is connected to the control system to quickly and accurately collect information about a single book (such as the title and ISBN code) and feed it back to the control system in real time. This provides data support for the subsequent precise sorting of the drive mechanism 32, solving the problems of low efficiency and error-proneness of manual recognition.

[0056] In some further embodiments, the first end of the main conveyor line 30 is provided with an elastic frame 6. The elastic frame 6 includes an auxiliary transmission belt 65 disposed above the conveyor belt in the main conveyor line 30. The auxiliary transmission belt 65 and the conveyor belt form a conveying channel for a single book to pass through. The elastic frame 6 also includes a baffle plate 64, which is used to limit other books above the bottom book in the stack of books.

[0057] An elastic frame 6 is fixedly installed at the beginning of the main conveyor line 30. The elastic frame 6 includes an auxiliary transmission belt 65. The auxiliary transmission belt 65 is set above the main conveyor line 30 conveyor belt through the bracket 10 and is parallel to the conveyor belt. A conveying channel is formed between the two, and the height of the channel only allows a single book to pass through.

[0058] The flexible rack 6 also includes a baffle plate 64, which is vertically set on one side of the input end of the auxiliary drive belt 65. The baffle plate 64 is higher than the height of the stack of books and is used to block other books above the bottom book in the stack to achieve the separation of individual books in the stack. The auxiliary drive belt 65 provides auxiliary driving force to ensure that individual books pass through smoothly, thereby solving the problem of the difficulty in automatically separating stacks of books, avoiding multiple books entering the recognition area at the same time and causing sorting errors, and improving sorting accuracy. The flexible design allows the conveyor channel to be slightly adapted to books of different thicknesses, enhancing versatility.

[0059] The bottom of the elastic frame 6 is provided with a guide rod 60, the main conveyor line 30 is provided with a guide plate, the guide plate is provided with a guide hole, the guide rod 60 is provided through the guide hole, and a locking nut 62 is screwed on one end of the rod, and a third spring 61 is provided between the locking nut 62 and the guide plate. A lever 63 is elastically hinged on the main conveyor line 30. The hinged end of the lever 63 is provided with a plug post 630. The main conveyor line 30 is provided with a plug groove 66. The plug post 630 is rotatably inserted into the plug groove 66. A first torsion spring is provided on the plug post 630. One end of the first torsion spring is connected to the plug post 630, and the other end is connected to the plug groove 66.

[0060] In some further embodiments, the tail end of the branch conveyor line 31 is provided with an elastic pressure roller 7; it also includes an inclined plate 70, the upper end of which is connected to the arc end of the tail end of the branch conveyor line 31 for receiving books, and the lower end of the inclined plate 70 is provided with a collection seat 71. A buffer plate 72 is hinged to the bottom of the end of the collection seat 71 facing the inclined plate 70. The buffer plate 72 is rotated by a servo motor 11. A sensor is provided on the inclined plate 70. Each time the sensor detects the passage of a book, the tilt angle of the buffer plate 72 decreases by one unit.

[0061] An elastic pressure roller 7 is installed at the end of the branch conveyor line 31. The elastic pressure roller 7 is set above the conveyor belt through the bracket 10 and can float up and down elastically. It is mainly used to press down the books and prevent the downstream section of the books from tilting downward and colliding with the inclined plate 70.

[0062] The upper end of the inclined plate 70 is connected to the arc end of the branch conveyor line 31. The downstream end of the pressed book can be directly placed on the upper end of the inclined plate 70 to achieve a transition, so as to receive the book conveyed from the branch conveyor line 31. The inclined plate 70 is set at an angle to guide the book to move towards the collection seat 71.

[0063] A buffer plate 72 is mounted on the bottom of the end of the collecting seat 71 facing the inclined plate 70 via a hinge shaft. The angle of the buffer plate 72 is controlled by a servo motor 11 to achieve dynamic adjustment of the tilt angle. A sensor is installed on the inclined plate 70 and is connected to the servo motor 11. Each time a book is detected passing by, a signal is sent to the control system, which then controls the tilt angle of the buffer plate 72 to decrease by one unit.

[0064] The angle of the buffer plate 72 is adjusted to accommodate the stacking height of books within the collection seat 71. The core effect is to prevent damage caused by height differences when books slip off the inclined plate 70. The buffer plate 72 gradually flattens with the stacking height, ensuring orderly stacking of books and improving the safety and neatness of the collection process.

[0065] The elastic pressure roller 7 is rotatably mounted on one end of the Z-shaped rod 80, and the other end of the Z-shaped rod 80 is rotatably mounted on the rotating seat, and a second torsion spring 81 is sleeved on it. One end of the second torsion spring 81 is connected to the rotating seat, and the other end is connected to the Z-shaped rod 80, so as to realize the pressure of the elastic pressure roller 7 on the vertical plate.

[0066] A sorting and conveying method using the above-mentioned book sorting and conveying device includes: under the action of the suspended conveyor line, the clamping mechanism 2 clamps stacks of different types of books and conveys them to the beginning of the main conveyor line 30. Then, the bottom book in the stack passes through the conveying channel. Afterward, the camera in the vision recognition system collects book information and feeds it back to the control system. The control system controls the corresponding pushing mechanism 32 to push the books onto the branch conveyor line 31 to collect books of the same type.

[0067] First, the overhead conveyor chain 1 drives the clamping mechanism 2 to the stacked books storage area. The clamping claws 20 of the clamping mechanism 2 close and the elastic pressure plate 22 presses down to firmly clamp the stacked books of different types. Then, the overhead conveyor chain 1 slides along the track to transport the stacked books to the beginning of the main conveyor line 30 and releases them.

[0068] After stacks of books are placed at the beginning of the main conveyor line 30, the bottom single book passes through the conveyor channel under the coordinated drive of the conveyor belt and the auxiliary transmission belt 65, while the other books above are limited by the baffle plate 64, thus achieving single book separation.

[0069] The individual book continues to be conveyed along the main conveyor line 30. The camera of the vision recognition system collects book information and feeds it back to the control system. The control system determines the corresponding branch conveyor line 31 based on the book type. When the book moves to the corresponding position, it controls the corresponding pushing mechanism 32 to push the book onto the target branch conveyor line 31. The book is conveyed along the branch conveyor line 31 to the end, guided by the elastic pressure roller 7, and then slides onto the inclined plate 70. The sensor detects the book passing through and triggers the angle adjustment of the buffer plate 72. The book finally lands smoothly on the buffer plate 72 of the collection seat 71, completing the collection of books of the same type. The core effect of this method is to achieve automated single-book separation, identification, sorting, and collection of stacked mixed books, greatly improving sorting efficiency, reducing manual intervention, and adapting to different types and sizes of books, making it highly versatile.

[0070] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
