[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a book sorting device, which has the following beneficial effects:

[0020] 1. The book sorting equipment uses an interception unit that can automatically reset and intercept the next book, so that the books can be fed intermittently and orderly. While feeding, the books are subjected to the pressure of the pressing plate and the feeding plate, which can smooth and flatten the surface or film of the books. It can also prevent the books from wrinkling when feeding. Compared with centralized batch sorting, it is more conducive to accurate sorting and avoids book confusion. The continuity between the various processes is strong and the execution is high. The accurately classified books in each recycling car are of the same type, which avoids the problem of confusion when the books are put on the shelves later and improves the efficiency of library work.

[0021] 2. The book sorting equipment uses visual probes to accurately identify book types and match them with database information, achieving accurate classification of books and avoiding chaotic stacking and wear and tear of books. Each book classification is clearer. The sorting unit automatically changes the unloading direction according to different types of books. The unloading unit cooperates with the sorting unit to automatically unload books, achieving continuity from loading to sorting to unloading, and reducing the burden of manual sorting.

[0022] 3. The book sorting equipment uses an intercepting part, a conveying part, a sorting part, a feeding part and a visual probe to form a lightweight automated sorting production line.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-7 The present invention provides a technical solution: a book sorting device, including two beams 1, the two beams 1 serving as a path for book transportation, which is an indispensable main structure of the technical solution of this case, the interception part 2 of this case is installed on the beam 1, and is used for automatically resetting and intercepting the next book, so that the books can be intermittently and orderly loaded and the wrinkles of the books can be flattened at the same time, the conveying part 3 of this case is installed between the two beams 1, and is used for automatically and intermittently conveying books, the sorting part 4 of this case is installed on the conveying part 3, and automatically changes the unloading direction according to different types of books, the unloading part 5 of this case is installed on the sorting part 4, and is used to cooperate with the sorting part 4 to automatically unload books, and the visual probe 9 of this case is used to accurately identify the type of books and match them with the database information.

[0033] In the present invention, in order to achieve an intermittent and orderly feeding effect between each book, the interception part 2 of the present case includes a connecting plate 21, and the number of the connecting plates 21 is two. The two connecting plates 21 are respectively installed on the top surfaces of the ends of the two beams 1. A rotating rod 22 is rotatably connected between the two connecting plates 21. An interception plate 23 is fixedly sleeved on the rotating rod 22. The interception plate 23 is located between the two beams 1. The interception plate 23 is used to block the next book to prevent multiple books or books of different types from entering the conveying process at the same time. Both ends of the rotating rod 22 are fixedly sleeved with sleeves 24. Each sleeve 24 is connected to the connecting plate 21 adjacent to itself. They are all elastically connected with torsion springs 25, and the rebound and reset ability of torsion springs 25 is used to prompt the intercepting plate 23 to always maintain a vertical state. Gears 26 are fixedly sleeved on both ends of the rotating rod 22. Four limit rods are slidably penetrated on the intercepting plate 23. A limit plate 27 is fixedly connected to the end of each limit rod close to the conveying part 3. A tension spring 28 is elastically connected between each limit plate 27 and the intercepting plate 23. A pressure plate 29 is fixedly connected to the other end of the four limit rods. The tension of the tension spring 28 can always keep the pressure plate 29 away from the intercepting plate 23. The top of the pressure plate 29 is a slope structure, and the slope is used to guide the book to slide and avoid jamming.

[0034] A machine groove is provided on the side where the two beams 1 are close to each other. In order to conveniently transport books to the identification link, the conveying part 3 in this case includes two linear motors 31. The two linear motors 31 are respectively installed on the inner walls of the two machine grooves and are symmetrically arranged with each other. The mover ends of the two linear motors 31 are fixedly connected with support arms 32, and the bottoms of the two support arms 32 are fixedly connected with conveying plates 33. The tops of the two support arms 32 are fixedly connected with the sides away from each other. Racks 34 are respectively connected. The conveying plate 33 is located between the two beams 1. The meshing parts of the two racks 34 are aligned with the meshing parts of the two gears 26. The racks 34 can mesh when contacting the gears 26, thereby driving the intercepting plate 23 to flip and be parallel to the beam 1. After the intercepting plate 23 is parallel, it will not block the next book.

[0035] In this embodiment, in order to further improve the automatic sorting effect of books, the sorting part 4 of this case includes a rotating motor 41, which is installed in the middle of the top of the conveying plate 33. The output shaft of the rotating motor 41 is fixedly connected with a rotating shaft 42, and the top of the rotating shaft 42 is fixedly connected with a feeding plate 43. The rotating motor 41 is used to rotate forward or reverse according to the degree set by the encoder to drive the feeding plate 43 to rotate synchronously to change the feeding direction of the book. The bottom of the feeding plate 43 is symmetrically installed with control arms 44 on both sides, and the top of the feeding plate 43 is symmetrically installed with baffles 45 on both sides. The baffles 45 In order to prevent books from falling from both sides during transportation, a button switch 46 is installed on the top of the conveying plate 33. The top side of the loading plate 43 is an inclined structure. The inclined structure is conducive to the books sliding onto the loading plate 43, and is also conducive to the books sliding off when unloading. The bottom side of the two control arms 44 are both inclined structures. The two control arms 44 and the button switch 46 are on the same circular path with the rotating motor 41 as the center. The loading plate 43 drives the control arms 44 to rotate synchronously, and at the positive and negative 90 degrees, one of the control arms 44 is just caused to come into contact and squeeze with the button switch 46.

[0036] It is worth noting that in order to further improve the automated unloading of books and thereby ensure the continuity from loading to sorting to unloading, the unloading portion 5 of this case includes a baffle plate 2 51, which is fixedly connected to the side of the top of the loading plate 43 away from the inclined surface, and the baffle plate 2 51 cooperates with the baffle plate 1 45 to further improve the protection effect on the books to prevent the books from falling, and the side of the baffle plate 2 51 away from the intercepting plate 23 is fixedly connected to a limiting arm 52, and an electric push rod 53 is installed between the top of the limiting arm 52 and the baffle plate 2 51, and the inner rod end of the electric push rod 53 is fixedly connected to a balancing arm 54, and both ends of the balancing arm 54 Both push arms 55 are fixedly connected, and the balance arm 54 has an equal distance from the electric push rod 53 to its two ends, which can improve the movement stability of the push arm 55. The limit arm 52 further limits the sliding trajectory of the push arm 55 to avoid the problem of large-scale shaking of the push arm 55 during movement. The two push arms 55 are both L-shaped structures, and one end of the two push arms 55 away from the balance arm 54 is attached to the top of the loading plate 43. The electric push rod 53 is electrically connected to the button switch 46. When the button switch 46 is squeezed by the control arm 44, the electric push rod 53 will be turned on to produce a contraction movement, otherwise the electric push rod 53 will produce an extension movement.

[0037] It is worth noting that the front sides of the bottoms of the two beams 1 are fixedly connected with front legs 6, and the rear sides of the bottoms of the two beams 1 are fixedly connected with rear legs 7. The front legs 6 and the rear legs 7 are used to support the beams 1 and enable the equipment in this case to reach a height for convenient operation. The two rear legs 7 are fixedly connected with brackets 8, and the visual probe 9 is installed on the top of the bracket 8. The model of the visual probe 9 can refer to the machine vision camera MV-CE060-10UC, which has high resolution and good image quality and is suitable for a variety of visual recognition applications. The signal between the visual probe 9 and the rotating motor 41 is connected, and the visual probe 9 takes pictures of the book This information is then calibrated with the information in the database to determine the type of the book, so that the unloading position of the loading plate 43 is adjusted by the rotating motor 41 for classified unloading. A chassis 10 is installed on the bracket 8, and a mobile power supply is arranged in the chassis 10. The mobile power supply can keep the equipment working normally for a period of time in a power-off or power-off state. The mobile power supply is electrically connected to the linear motor 31, the rotating motor 41, the button switch 46, the electric push rod 53, and the visual probe 9 respectively. Recycling carts 11 are arranged on both sides of the bracket 8. The recycling cart 11 is aligned with the space between the end of the beam 1 and the bracket 8 to facilitate the classified unloading and recycling of books.

[0038] Working principle: compared with industrial assembly line sorting, the equipment in this case has a simple and compact structure. It occupies a small area when used in library warehouses, and has low mechanical noise, making it more convenient and safer to use. The conveyor belt device in the prior art is aligned in front of the interception plate 23, and the books are placed on the conveyor belt one by one in an orderly manner. The movable end of the linear motor 31 is controlled to drive the support arm 32 to move toward the interception plate 23, prompting the rack 34 to engage the gear 26, and then the gear 26 drives the rotating rod 22 to rotate, prompting the interception plate 23 to flip from vertical to parallel to the beam 1. At this time, the space between the front ends of the two beams 1 is opened, and the first book enters the space. It first slides under the pressing plate 29 through the inclined surface of the pressing plate 29, and fits with the pressing plate 29, thereby flattening the upper surface or film of the book. The tension spring 28 is free to elastically expand and contract to adapt to the thickness of the book to ensure a certain downward pressure on the book. Then the book moves along the feeding plate 43 The inclined surface slides into the loading plate 43. At this time, the book is still subjected to the downward pressure of the pressure plate 29 and the pushing force of the conveyor belt, and then the lower surface or film of the book is flattened until the book is away from the pressure plate 29 and completely enters the top of the loading plate 43. At this time, the baffle 1 45 and the baffle 2 51 can play a role in shielding and preventing it from falling. The linear motor 31 drives the support arm 32 to move toward the rear end of the beam 1, and the rack 34 drives the gear 26 to rotate and prompts the intercepting plate 23 to flip from parallel to perpendicular to the beam 1, thereby continuing to close the space between the front ends of the two beams 1. The torsion spring 25 ensures the vertical stability of the intercepting plate 23 through torque to prevent the intercepting plate 23 from being squeezed open by subsequent books, and then it is easier to block the next book on the conveyor belt device, thereby realizing intermittent loading. Compared with centralized batch sorting, the equipment in this case is more reflected in further precise sorting, making each book classification clearer, and avoiding wear and damage caused by chaotic stacking of books.

[0039] When the arm 32 moves to the rear end of the beam 1, the conveying plate 33 extends to the outside of the rear ends of the two beams 1 and stays suspended in the space between the beam 1 and the bracket 8. At this time, the visual probe 9 verifies the corresponding information of the book by recording the book on the loading plate 43, and according to the preset program, for example, if the book is classified as A, the electric signal of the visual probe 9 responds to the rotating motor 41 to produce a positive rotation of 90 degrees. If the book is classified as B, the electric signal of the visual probe 9 responds to the rotating motor 41 to produce a reverse rotation of 90 degrees. Regardless of whether it is forward or reverse, the rotating motor The machine 41 will drive the control arm 44 to rotate synchronously, and after ninety degrees, there will definitely be a control arm 44 that is squeezed with the button switch 46, and the electric push rod 53 will be turned on to cause its inner rod to contract, so that the push arm 55 is driven by the balance arm 54 to move on the loading plate 43, and then the book is pushed down from the loading plate 43 and falls into the recycling cart 11. The number of recycling carts 11 in this case should include at least two or more according to actual applications, and different recycling carts 11 can be replaced by themselves according to different book types, so as to achieve an automatic sorting effect for books.

[0040] After the electric push rod 53 pushes the book to be unloaded, each component is reset in turn through program control, that is, the rotating motor 41 rotates 90 degrees in the opposite direction to reset, the button switch 46 is not squeezed and the inner rod of the electric push rod 53 extends to drive the push arm 55 to reset, and the linear motor 31 drives the conveying plate 33 to reset close to the intercepting plate 23 through the support arm 32, and reopens the intercepting plate 23 after the gear 26 and the rack 34 are engaged. The above steps are adopted and cooperated with the conveyor belt device to carry out the loading and sorting of the next book. The continuity between the processes is strong, the execution is high and the sorting is accurate. The relationship between loading, identifying the book information and sorting and unloading is close, which reduces the burden of manual sorting. At the same time, the books accurately classified in each recycling vehicle 11 are of the same type, which avoids the problem of confusion when the books are put on the shelves later, and improves the convenience of library work.

[0041] In the application of this case, the visual probe 9 usually needs to be used in conjunction with a computer, image processing software and a controller. The image processing software usually runs on a computer, so the visual probe 9 needs to be connected to the computer to transmit the image data to the computer for processing. The visual probe 9 needs to be connected to the controller to pass the recognition results to the controller. The controller controls the actions of other devices based on these results. The images collected by the visual probe 9 need to be analyzed and processed by the image processing software. These software can enhance, filter, segment, recognize and other operations on the images to extract useful information. For example, computers, controllers and other related circuit equipment can be installed in the chassis 10 of this case. This is a technology that relevant technicians in the prior art can master, and this case will not be elaborated in detail.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
