Technical Field

[0001] The utility model relates to the technical field of book sorting, and more specifically, it relates to a book sorting device. Background Art

[0002] Book sorting is an important step in the circulation process of a library. It involves the process of classifying and putting back the books returned by readers or newly stocked into the library according to certain standards and methods. The efficiency and accuracy of book sorting are crucial for ensuring the high efficiency and quality of library services. In the existing book sorting, books need to be moved and sorted into different book recycling bins according to categories.

[0030] In this embodiment, during sorting, start the conveyor belt assembly 3, place the books on the conveyor belt assembly 3 for movement. According to the types of books, start the driving cylinder 9. The movement of the driving cylinder 9 is realized by controlling the pneumatic solenoid valve through a PLC programmable logic controller. The output end of the driving cylinder 9 drives the second support rod 7 to rotate. When the second support rod 7 rotates, the second support rod 7 drives the guiding block 26 and the guiding wheel 27 to move on the guiding track 25, and then drives one end of the guiding frame 5 to rotate around the first support rod 6, thereby adjusting the direction of the guiding frame 5. Through the cooperation of two groups of guiding devices, the moving direction of the books on the conveyor belt assembly 3 is adjusted, so that when the books move to the end of the conveyor belt assembly 3, they can enter different types of book recycling bins, and thus the book sorting work is completed.

[0031] Please refer to Figures 4-5 , as an implementation manner of the pin shaft 10: an oil inlet pipe 15 is communicated with one side of the oil inlet cavity 11, a moving block 16 is provided in the oil inlet cavity 11, a moving spring 17 is provided between the moving block 16 and the oil inlet cavity 11, a moving plate 18 is provided on the moving block 16, a pressing rod 19 is slidably provided on the pin shaft 10, a piston plate 20 is provided at one end of the pressing rod 19, a baffle 21 is provided between the lubricating cavity 12 and the oil outlet cavity 13, a blocking block 22 is provided on the baffle 21, a limiting sleeve 23 is provided at the bottom of the oil outlet cavity 13, and a limiting spring 24 is provided between the limiting sleeve 23 and the blocking block 22.

[0032] More specifically, the fixed seat 8 and the driving cylinder 9, as well as the driving cylinder 9 and the second support rod 7, are hinged by a pin shaft 10. When injecting lubricating oil into the pin shaft 10, the extrusion rod 19 and the piston plate 20 are lifted upward. The piston plate 20 moves upward, drives the moving block 16 to move upward through the moving plate 18, and compresses the moving spring 17. After the moving block 16 moves upward, the oil inlet pipe 15 is opened, and lubricating oil is injected into the lubricating cavity 12 through tools such as a syringe. The lubricating oil enters the lubricating cavity 12 through the oil inlet cavity 11 for storage. When the oil injection is completed, the extrusion rod 19 is released. Under the elastic force of the moving spring 17, the moving block 16 drives the moving plate 18 and the piston plate 20 to move downward. When the moving block 16 moves to the bottom of the oil inlet cavity 11, the oil inlet pipe 15 is blocked, completing the sealing of the lubricating oil. At the same time, when lubricating the periphery of the pin shaft 10, the extrusion rod 19 is pressed. The extrusion rod 19 drives the piston plate 20 to move downward by a certain distance. The piston plate 20 presses the lubricating oil downward, and the lubricating oil presses the stopper 22 and the limit spring 24 downward, so that the lubricating oil enters the oil outlet cavity 13 through the baffle 21 and overflows to the outside of the pin shaft 10 under pressure to lubricate the outside of the pin shaft 10. After the piston plate 20 stops moving, the stopper 22 moves upward under the elastic force of the limit spring 24 to block the baffle 21, realizing the sealing of the lubricating oil in the lubricating cavity 12, preventing problems such as leakage and pollution of the lubricating oil. By lubricating the outside of the pin shaft 10, the rotational wear between the fixed seat 8 and the driving cylinder 9, as well as between the driving cylinder 9 and the second support rod 7, is reduced, the maintenance frequency of the device is lowered, and the practicability of the sorting device is improved.

[0033] In summary, when the overall equipment is in use or operation: during sorting, the conveyor belt assembly 3 is started, and the books are placed on the conveyor belt assembly 3 for movement. According to the types of books, the driving cylinder 9 is started. The movement of the driving cylinder 9 is realized by controlling the pneumatic solenoid valve through a PLC programmable logic controller. The output end of the driving cylinder 9 drives the second support rod 7 to rotate. When the second support rod 7 rotates, the second support rod 7 drives the guide block 26 and the guide wheel 27 to move on the guide track 25, and then drives one end of the guide frame 5 to rotate around the first support rod 6, thereby adjusting the direction of the guide frame 5. Through the cooperation of the two groups of guiding devices, the moving direction of the books on the conveyor belt assembly 3 is adjusted, so that when the books move to the end of the conveyor belt assembly 3, they can enter different types of book recycling bins, thus completing the sorting work of the books.

[0034] The fixed seat 8 and the driving cylinder 9, as well as the driving cylinder 9 and the second support rod 7, are hinged by a pin shaft 10. When injecting lubricating oil into the pin shaft 10, the extrusion rod 19 and the piston plate 20 are lifted upward. The piston plate 20 moves upward and drives the moving block 16 to move upward through the moving plate 18, compressing the moving spring 17. After the moving block 16 moves upward, the oil inlet pipe 15 is opened, and lubricating oil is injected into the lubricating cavity 12 through tools such as a syringe. The lubricating oil enters the lubricating cavity 12 through the oil inlet cavity 11 for storage. When the oil injection is completed, the extrusion rod 19 is released. Under the elastic force of the moving spring 17, the moving block 16 drives the moving plate 18 and the piston plate 20 to move downward. When the moving block 16 moves to the bottom of the oil inlet cavity 11, the oil inlet pipe 15 is blocked, completing the sealing of the lubricating oil. At the same time, when lubricating the periphery of the pin shaft 10, the extrusion rod 19 is pressed. The extrusion rod 19 drives the piston plate 20 to move downward a certain distance. The piston plate 20 presses the lubricating oil downward. The lubricating oil presses the stopper 22 and the limit spring 24 downward, so that the lubricating oil enters the oil outlet cavity 13 through the baffle 21 and overflows to the outside of the pin shaft 10 under pressure to lubricate the outside of the pin shaft 10. After the piston plate 20 stops moving, the stopper 22 moves upward under the elastic force of the limit spring 24 to block the baffle 21, realizing the sealing of the lubricating oil in the lubricating cavity 12, preventing problems such as leakage and pollution of the lubricating oil. By lubricating the outside of the pin shaft 10, the rotational wear between the fixed seat 8 and the driving cylinder 9, as well as between the driving cylinder 9 and the second support rod 7, is reduced, the maintenance frequency of the device is lowered, and the practicability of the sorting device is improved.

Since the devices matched with the controller are common devices and belong to the existing mature technologies, the electrical connection relationships and the specific circuit structures are not described herein again. For the connection between two components, welding, the cooperation of bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which are not described one by one herein.
