Description

Technical Field

[0001] This utility model relates to the field of logistics sorting technology, and in particular to a sorting line conveyor device with a buffer structure. Background Technology

[0002] As a key piece of equipment in modern logistics sorting, the core design of the buffered sorting line conveyor system utilizes barcode scanning, machine vision, and laser measurement to automatically identify the destination, category, and size of items. A high-speed sorting mechanism then accurately and efficiently distributes these items to designated paths or compartments. The system's core function is to achieve automatic identification, high-speed classification, and accurate diversion of massive quantities of items, significantly improving logistics efficiency and reducing labor costs and error rates. Furthermore, the system's sorting function solves the material accumulation problem inherent in traditional sorting lines and, through its flexible buffered structure, reduces the risk of damage to fragile and delicate items during transport, significantly enhancing the stability and adaptability of the sorting device.

[0003] Although the sorting line conveyor with a buffer structure ensures sorting efficiency, dust and material debris will accumulate in the gaps between the rollers after prolonged use. This will affect the smoothness of the roller rotation and increase the frequency of maintenance. At the same time, due to the relatively compact structure, the operating space is limited when cleaning, repairing, and replacing the rollers, increasing the difficulty of maintenance. The existing solution is to optimize the roller gap structure by improving the design and installation of the rollers to reduce the gap between them, making it difficult for dust and debris to enter and reducing dust accumulation at the source. However, excessively reducing the roller gap will increase the friction between the rollers, which will affect the rotation flexibility of the rollers and may even cause the rollers to jam.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a cleaning scraper is attached to a rotating rubber cylinder to scrape off surface impurities, and gravity causes the impurities to fall into the collection shell. At the same time, a centrifugal fan is started, and the suction generated forms a negative pressure through the pipe, which in turn sucks up the small impurities between the rubber cylinder and the conveyor shaft and collects them into the collection shell.

In this utility model, the left rotating shaft is driven by a servo motor, and the power is transmitted through the meshing connection between the conveyor belt and the rotating shaft, which drives the right rotating shaft to rotate synchronously, thereby realizing the transmission of goods. When the tension of the conveyor belt is abnormal, the electric telescopic rod makes a telescopic movement, which drives the rotating drum to move up and down to adjust the tension of the conveyor belt, ensuring the smooth transportation of goods, avoiding slippage or jamming of goods, and improving the efficiency and reliability of goods transportation.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a sorting line conveying device with a buffer structure, comprising two vertical frames 1 and multiple horizontal frames 2. The vertical frames 1 and horizontal frames 2 serve as the main support structures, and the horizontal frames 2 are fixed on the opposite side of the two vertical frames 1. A cleaning mechanism 3 is provided at the bottom of the two vertical frames 1. The cleaning mechanism 3 is used to remove impurities from the outer wall of the rubber cylinder 602 and the gap between the rubber cylinder 602 and the conveying shaft 601. Multiple support legs 4 are fixedly connected to the opposite side of the two vertical frames 1 and the multiple horizontal frames 2. The multiple support legs 4 can keep the device away from the ground to avoid moisture. A connecting mechanism 5 is provided on the adjacent side of the two vertical frames 1. The connecting mechanism 5 is used to enable goods to enter the sub-conveying area more smoothly from the main conveying area. A buffer mechanism 6 is provided on the adjacent side of the two vertical frames 1 and the multiple horizontal frames 2. The buffer mechanism 6 can buffer the transport of goods. A moving mechanism 7 is provided at the bottom of the multiple support legs 4. The moving mechanism 7 is used to move the entire device.

[0035] The cleaning mechanism 3 includes multiple fixed rods 301. The tops of the multiple fixed rods 301 are fixedly connected to the bottoms of two vertical frames 1 and multiple horizontal frames 2. Cleaning scrapers 302 are fixedly connected to adjacent sides of the multiple fixed rods 301. The cleaning scrapers 302 are used to clean impurities from the outer wall of the rubber cylinder 602. Collection shells 303 are fixedly connected to the bottoms of the multiple fixed rods 301. The collection shells 303 are used to collect the scraped impurities and suck out the impurities from the gaps using the suction of the centrifugal fan 307. The bottoms of the multiple collection shells 303 in the middle are all connected to the same dust collection pipe 304, and the bottoms of the multiple collection shells 303 on the left and right sides are all connected to the same dust collection pipe 305. Dust collection pipe 1 304 and dust collection pipe 2 305 collect impurities into storage box 306. Storage box 306 is fixedly connected to the right side of front support leg 4. Storage box 306 is used to collect the collected impurities. Centrifugal fan 307 is fixedly connected to the left side of rear support leg 4. Centrifugal fan 307 is used to provide suction. The front end of centrifugal fan 307 is connected to exhaust pipe 308. Exhaust pipe 308 is used to transmit suction. Filter screen 309 is fixedly connected to the left side of storage box 306. Filter screen 309 can prevent impurities from entering centrifugal fan 307 from storage box 306. Dust removal component 310 is set inside storage box 306. Dust removal component 310 is used to remove impurities inside storage box 306.

[0036] The dust removal component 310 includes a dust collection shell 3101. The bottom of the dust collection shell 3101 is slidably connected to the bottom of the inner wall of the storage box 306. The dust collection shell 3101 can easily extract and remove dust. The front side of the storage box 306 is rotatably connected to an inspection door 3102. The inspection door 3102 can prevent impurities in the air inside the storage box 306 from escaping to the outside.

[0037] Specifically, during device operation, the cleaning scraper 302 closely adheres to the outer wall of the rubber cylinder 602. As the rubber cylinder 602 rotates, the scraper removes dust and debris adhering to its surface. The debris falls into the collection shell 303 directly below due to gravity. Simultaneously, the rear centrifugal fan 307 is activated. The suction generated by the centrifugal fan 307 is transmitted to the collection box 306 via the exhaust pipe 308, and then dispersed into each collection shell 303 via dust collection pipe one 304 and dust collection pipe two 305. This process cleans the rubber cylinder 602 and the conveyor shaft 601. The gap between the two parts creates a continuous extraction process, sucking in the fine impurities remaining in the gap into the collection shell 303. The impurities in the collection shell 303 are then collected into the storage box 306 via the dust collection pipe. The filter screen 309 prevents impurities from entering the fan, causing the impurities to eventually fall into the dust accumulation shell 3101. When it is necessary to clean the impurities in the dust accumulation shell 3101, the inspection door 3102 on the front side of the storage box 306 is opened, the dust accumulation shell 3101 is pulled out and the internal impurities are poured out. After cleaning, it is reset. The overall operation is simple, reduces the accumulation of dust, and avoids affecting the rotation flexibility of the roller.

[0038] Reference Figure 1 , Figure 5 and Figure 6 The connecting mechanism 5 includes two connecting legs 501, which serve as a connector. The tops of the two connecting legs 501 are fixedly connected to the bottoms of the two vertical frames 1. The same support plate 502 is fixedly connected to the adjacent side of the two connecting legs 501. The support plate 502 is used to support the rotating shaft 505. Two support frames 503 are fixedly connected to the front and rear sides of the support plate 502. The support frames 503 are used to support the servo motor 504. The front side of the right front support frame 503 is fixedly connected to the servo motor 504. The output end of the servo motor 504 is fixedly connected to the front end of the left rotating shaft 505. The rotating shaft 505 is fixedly connected to the adjacent side of the multiple support frames 503. The outer walls of the two rotating shafts 505 are connected by a conveyor belt 506. The conveyor belt 506 transfers goods from the main conveying area to the sub-conveying area. An adjustment component 507 is provided on the top of the support plate 502. The adjustment component 507 is used to adjust the tension of the conveyor belt 506 to ensure conveying efficiency.

[0039] The adjustment assembly 507 includes an electric telescopic rod 5071, which causes the rotating drum 5073 to move up and down. The bottom of the electric telescopic rod 5071 is fixedly connected to the top left side of the support plate 502, and the top of the electric telescopic rod 5071 is fixedly connected to a fixing frame 5072. The rotating drum 5073 is rotatably connected to the adjacent side of the fixing frame 5072. The tension of the conveyor belt 506 is adjusted by the up and down movement of the rotating drum 5073.

[0040] Specifically, during operation, the servo motor 504 is activated to drive the left rotating shaft 505 to rotate. Through the meshing connection between the conveyor belt 506 and the rotating shaft 505, the right rotating shaft 505 rotates synchronously, thereby transporting goods from the main conveying area to the conveyor belt 506, and then smoothly transitioning to the sub-conveying area. When the conveyor belt 506 becomes loose or too tight, the electric telescopic rod 5071 is activated to extend or retract, causing the fixed frame 5072 and the rotating drum 5073 to move up and down. When the rotating drum 5073 moves upward, the conveyor belt... When 506 is lifted, the tension of the conveyor belt 506 increases, while when it moves downward, the tension of the conveyor belt 506 decreases. This precisely adjusts the tension of the conveyor belt 506, ensuring that it can fit against the rotating shaft 505 and smoothly transfer goods. This guarantees the stability and efficiency of the goods connection process and prevents the conveyor belt 506 from slipping or getting stuck with the goods. The connecting leg 501, support plate 502, and support frame 503, as components that stabilize and support the entire connecting mechanism 5, ensure the stable operation of the rotating shaft 505 and the motor.

[0041] Reference Figure 2 , Figure 5 and Figure 7 The buffer mechanism 6 includes multiple transmission shafts 601, which are used to transmit power. The outer walls of the multiple transmission shafts 601 are fixedly connected to the adjacent sides of two vertical frames 1 and multiple horizontal frames 2. Rubber cylinders 602 are fixedly connected to the outer walls of the multiple transmission shafts 601 to dampen vibration through the material of the rubber cylinders 602 themselves. The moving mechanism 7 includes multiple connecting rods 701, the tops of the multiple connecting rods 701 are fixedly connected to the bottoms of multiple support legs 4, and the bottoms of the multiple connecting rods 701 are rotatably connected to two universal wheels 702. The device is movable by casters 702. A fixed column 508 is fixedly connected to the top right side of the support plate 502. The fixed column 508 is used to raise the height of the pressure sensor 509. The pressure sensor 509 is fixedly connected to the top of the fixed column 508. The pressure sensor 509 is used to detect the tension of the conveyor belt 506. A monitor 8 is fixedly connected to the top of the right vertical frame 1. The monitor 8 is used to detect the information of the express package. A buzzer 9 is fixedly connected to the top of the monitor 8. The buzzer 9 can sound an alarm in case of an accident.

[0042] Specifically, during operation, the multiple conveyor shafts 601 rotate, causing the rubber cylinders 602 on the outer walls of the conveyor shafts 601 to rotate synchronously. The rubber cylinders 602 utilize the elasticity of their rubber material to mitigate vibrations and reduce impact between the goods and the rubber cylinders 602 during transport. When moving the device, the connecting rods 701 at the bottom of the support legs 4 cooperate with the casters 702, allowing the device to move as a whole by utilizing the flexible rotation of the casters 702. The fixed column 508 on the support plate 502 supports the pressure sensor 509, which detects the tension of the conveyor belt 506 in real time. The monitor 8 at the top of the right vertical frame 1 scans the passing express packages to collect information. When there is an abnormality in the conveyor belt 506 or when goods are stuck, the buzzer 9 sounds an alarm to remind staff to handle the situation promptly, ensuring the stable operation of the device.

[0043] Working principle: By tightly adhering the cleaning scraper 302 to the outer wall of the rubber cylinder 602, the relative motion of the rotating rubber cylinder 602 scrapes off the dust and debris adhering to its surface. Gravity then allows the impurities to fall naturally into the collection shell 303 below, achieving initial cleaning of the outer wall of the rubber cylinder 602. Simultaneously, the centrifugal fan 307 is activated to generate negative pressure, and the suction force is transmitted through the exhaust pipe 308 and the collection box 306 to the dust collection pipe 304 and the second dust collection pipe 305, where the dust is collected in the collection shell 302. The system generates continuous suction, which uses negative pressure to suck up small residual impurities in the gap between the rubber cylinder 602 and the conveyor shaft 601, avoiding the presence of impurities in the dead corner between the rubber cylinder 602 and the conveyor shaft 601. The collected impurities accumulate in the collection box 306 through the pipe, and the filter screen 309 prevents impurities from entering the fan, so that the impurities are deposited in the dust collection shell 3101. The impurities are cleaned by manually pulling out the dust collection shell 3101, which effectively reduces the accumulation of dust and ensures the flexibility of the roller rotation.

[0044] Furthermore, the servo motor 504 provides power to drive the left rotating shaft 505 to rotate. The meshing connection between the conveyor belt 506 and the rotating shaft 505 causes the right rotating shaft 505 to rotate synchronously, forming a continuous transmission path. This ensures a smooth transition of goods from the main transmission area to the sub-transmission area. When the tension of the conveyor belt 506 becomes abnormal, the extension and retraction of the electric telescopic rod 5071 is controlled, causing the fixed frame 5072 and the rotating drum 5073 to move up and down. The upward movement of the rotating drum 5073 increases the tension of the conveyor belt 506, while its downward movement decreases the tension, thus dynamically adjusting the tension of the conveyor belt 506. Simultaneously, the connecting leg 501, support plate 502, and support frame 503 form a support structure, ensuring the stable operation of the rotating shaft 505 and the motor, guaranteeing a tight fit between the conveyor belt 506 and the rotating shaft 505, preventing goods from slipping or jamming, and achieving efficient and stable goods transmission.
