Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more specifically, to a suspended conveyor for logistics sorting. Background Technology

[0002] Intelligent overhead conveyor systems have become core conveying equipment in e-commerce warehousing, express delivery distribution centers and other scenarios due to their advantages of high space utilization and the ability to realize the entire process of suspended conveying and automatic sorting of goods. At present, overhead conveyors used in high-volume sorting scenarios generally have the characteristics of high speed and heavy load operation. The number of suspension frames on a single line can reach hundreds. As a key load-bearing component of each suspension frame, the bearing's operating status is crucial to the continuous operation capability of the whole machine.

[0003] There are two main types of bearing lubrication methods for existing overhead conveyors. One is one-time pre-lubrication before leaving the factory, which involves filling the bearing with a sufficient amount of grease during assembly and relying on the natural diffusion of the grease to achieve long-term lubrication. The other is manual lubrication and replenishment during periodic shutdowns, which involves stopping the entire machine and manually disassembling the suspension frame or bearing end cover to replenish the bearing with grease. However, both methods have certain drawbacks: one-time pre-lubrication cannot be adapted to long-term operation under high speed and heavy load conditions, and in severe cases, bearing seizure may occur, causing suspension frame jamming, uneven stress on the traction chain, or even breakage, resulting in a complete shutdown. While manual lubrication and replenishment during periodic shutdowns can extend bearing life, it requires frequent interruptions of sorting operations, which significantly reduces conveying efficiency and brings many inconveniences to actual production.

[0004] To address the aforementioned issues, a suspended conveyor for logistics sorting is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a suspended conveyor for logistics sorting is provided. This technical solution solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions: This invention provides a suspended conveyor for logistics sorting, comprising: The track assembly includes a suspension rail, multiple suspension brackets suspended below the suspension rail, mounting shafts symmetrically fixedly connected to both sides of the top of the suspension brackets, bearings fixedly fitted outside the mounting shafts, and end caps provided on both sides of the bearings. The grease storage assembly includes a grease storage cavity opened in the mounting shaft, a support ring fixedly fitted on one end of the mounting shaft, the support ring being fixedly connected to a side end cap, and multiple channels opened inside the support ring. Output holes and input holes are respectively opened on the mounting shaft and the end cap at the positions corresponding to the channels. The lubrication assembly includes a piston that slides in a grease reservoir, a protective tube that is threaded to the end of the mounting shaft away from the suspension rail, a permanent magnet that slides in the protective tube and is fixedly connected to one end of the piston, an exhaust port at the bottom of the protective tube, a support frame that is fixedly connected to the suspension rail bracket above the suspension rail, and electromagnets that are fixedly installed on both sides of the bottom of the support frame. When the electromagnets are energized, they are opposite to the same pole of the permanent magnet. The piston is driven by the electromagnetic repulsion between the electromagnet and the permanent magnet, which in turn forces the grease in the grease reservoir into the bearing through the output hole, channel and input hole in sequence, so as to achieve active grease replenishment without stopping the machine.

[0007] Furthermore, the outer ring of the bearing rolls onto the two flange surfaces of the suspension rail.

[0008] Furthermore, rubber sheets for shielding the inside of the protective pipe are fixedly connected to both sides of the bottom of the exhaust port.

[0009] Furthermore, each electromagnet consists of at least two electromagnetic coils arranged side by side along the running direction of the suspension frame. After the electromagnetic coils are energized synchronously, they will form an electromagnetic repulsion area with a length of 0.5-1.0m along the running direction in the running path of the suspension frame. The electromagnetic repulsion is generated by the electromagnetic coils and permanent magnets with the same pole facing each other after being energized.

[0010] Furthermore, the bracket, mounting shaft, and protective tube are all made of non-magnetic materials.

[0011] Furthermore, the inner diameters of the channel, output port, and input port are the same, ranging from 2.0 to 4.0 mm.

[0012] Furthermore, it also includes a drive assembly for driving the suspension frame to rotate and move along the suspension rail as a whole. It includes a traction chain arranged below the suspension rail path, with the suspension frames connected in series and fixed on the traction chain. A wheel frame fixedly connected to the suspension rail bracket is provided on the side of the traction chain. Two sprockets are rotatably connected to both sides of the bottom of the wheel frame. A motor is fixedly mounted on the top of the wheel frame. The drive end of the motor is fixedly connected to the shaft of any one of the sprockets. A drive chain is supported by the two sprockets and meshes with them. Multiple chain teeth are evenly fixedly connected around the outer circumference of the drive chain. The drive chain is meshed with the traction chain through the chain teeth.

[0013] Furthermore, the drive assembly also includes a support arm for maintaining the engagement of the drive chain and the traction chain. The support arm is located between two sprockets below the wheel frame, with the side of the support arm away from the wheel frame abutting against the drive chain, supporting the drive chain outward and abutting against the side of the traction chain.

[0014] As described above, the features and advantages of the overhead conveyor for logistics sorting in this invention are: This solution utilizes a pre-stored grease reservoir within the mounting shaft, combined with a connecting channel integrated with the support ring and end cap, and a non-contact drive structure between the track-side electromagnet and the piston, to achieve active and continuous lubrication of the bearings. This completely eliminates the passive mode of relying on natural grease diffusion, effectively preventing malfunctions such as bearing jamming, suspension frame jamming, uneven force on the traction chain, or even breakage caused by insufficient grease. Addressing the shortcomings of periodic manual lubrication requiring frequent interruptions to sorting operations and significantly reducing conveying efficiency, this solution adopts a non-stop lubrication design synchronized with the conveyor operation. The lubrication action is automatically completed as the suspension frame passes through the electromagnet's action area, without requiring the entire machine to be stopped, thus reducing the interference of lubrication operations on the sorting process.

[0015] This solution, through the pre-stored grease design in the grease reservoir, significantly extends the cycle of manual lubrication and reduces the number of maintenance operations requiring manual disassembly of suspension frames and bearing end covers at heights. This reduces the labor intensity and operational risks for maintenance personnel, further minimizing equipment downtime for maintenance. Furthermore, the solution allows for precise control of the electromagnetic repulsion force by adjusting the working intensity of the electromagnet, thereby enabling flexible adjustment of the piston stroke and the amount of lubrication. This overcomes the drawback of relying solely on experience for manual lubrication, ensuring that the amount of lubrication precisely matches the actual lubrication needs of the bearings. Ultimately, this achieves a dual improvement in sorting and conveying efficiency and equipment maintenance economy. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] See Figures 1-8 As shown, an embodiment of the present invention is provided, and a suspended conveyor for logistics sorting will be described in detail below: See Figures 1-5 As shown, a suspended conveyor for logistics sorting includes a track assembly comprising a suspension rail 11, multiple suspension frames 12 suspended below the suspension rail 11, mounting shafts 13 symmetrically fixedly connected to both sides of the top of the suspension frames 12, bearings 14 fixedly fitted onto the outside of the mounting shafts 13, and end caps 15 disposed on both sides of the bearings 14 (the end caps 15 are placed according to existing technology). Furthermore, in this embodiment, the outer ring of the bearing 14 rolls onto the flange surfaces on both sides of the suspension rail 11, meaning the outer ring of the bearing 14 is directly used as a roller. Alternatively, a wheel rim can be fitted onto the outside of the outer ring to improve the rolling effect and reduce wear on the bearing 14; this is a common technical method, and similar methods will not be described in detail here. See reference. Figures 4-5 As shown, the overhead conveyor for logistics sorting also includes a grease storage assembly, which includes a grease storage chamber 21 opened in the mounting shaft 13, a support ring 22 fixedly fitted on one end of the mounting shaft 13, the support ring 22 being fixedly connected to a side end cover 15, and multiple channels 23 being opened inside the support ring 22. The two ends of the channels 23 are respectively connected to the mounting shaft 13 and the bearing 14. An output hole 24 is provided at the position where the channel 23 is connected to the mounting shaft 13, and an input hole 25 is provided at the position where the channel 23 is connected to the end plate 15 of the bearing 14.

[0020] See Figures 4-6As shown, the overhead conveyor for logistics sorting also includes a lubrication assembly, which includes a piston 31 that is slidably fitted in the grease storage chamber 21, a protective tube 33 that is threadedly connected to the end of the mounting shaft 13 away from the suspension rail 11, a permanent magnet 32 ​​that is slidably fitted in the protective tube 33 and fixedly connected to one end of the piston 31, an exhaust port 34 opened at the bottom of the protective tube 33, a support frame 36 that is fixedly connected to the support bracket of the suspension rail 11 above the suspension rail 11, and electromagnets 37 that are fixedly installed on both sides of the bottom of the support frame 36. When the electromagnets 37 are energized, they are opposite to the permanent magnet 32 ​​with the same pole.

[0021] It should be noted that the suspension rail 11 shown in this embodiment is an I-shaped track structure, and two symmetrically arranged bearings 14 are located in the grooves on both sides of the I-shaped suspension rail 11, i.e., attached... Figure 6 The Y-shaped structure allows the suspension frame 12 to move freely on the suspension rail 11. However, there are other structures such as the C-shaped single-side suspension structure and the T-shaped suspension frame structure (with rollers on the left and right sides of the suspension frame and the suspension rail 11 having an n-shaped structure, holding the rollers on the left and right sides). These structures can also adopt the structure of this solution by modifying them to a certain extent (i.e., the improved mounting shaft 13 and the permanent magnet 32 ​​arrangement structure that meets the shape requirements of the track and suspension frame 12), and should also fall within the protection scope of this solution.

[0022] For further details, please refer to [link / reference]. Figure 1 and Figures 7-8 As shown, the overhead conveyor for logistics sorting also includes a drive assembly for driving the suspension frame 12 to rotate and move along the suspension rail 11. The drive assembly includes a traction chain 41 arranged below the suspension rail 11. The suspension frames 12 are connected in series and fixed on the traction chain 41. A wheel frame 42 is provided on the side of the traction chain 41 and fixedly connected to the support of the suspension rail 11. Two sprockets 43 are rotatably connected to the bottom sides of the wheel frame 42. A motor 44 is fixedly mounted on the top of the wheel frame 42. The drive end of the motor 44 is fixedly connected to the shaft of any one of the sprockets 43. The two sprockets 43 support and mesh with a drive chain 45. Multiple chain teeth are evenly fixedly connected around the outer circumference of the drive chain 45. The drive chain 45 meshes with the traction chain 41 through the chain teeth, thereby driving the traction chain 41 to move.

[0023] Furthermore, the drive assembly also includes a support arm 46 for maintaining the drive chain 45 and the traction chain 41 in an engaged state. The support arm 46 is disposed between two sprockets 43 below the wheel frame 42. The side of the support arm 46 away from the wheel frame 42 abuts against the drive chain 45, supporting the drive chain 45 outward and abutting against the side of the traction chain 41.

[0024] When the suspension frame 12 passes through the area where the electromagnet 37 is installed, the electromagnetic repulsion between the electromagnet 37 and the permanent magnet 32 ​​pushes the piston 31, which in turn presses the grease in the grease storage chamber 21 into the bearing 14 in a measured amount through the output hole 24, the channel 23, and the input hole 25, so as to achieve active grease replenishment without stopping the machine.

[0025] Furthermore, rubber sheets 35 are fixedly connected to both sides of the bottom of the exhaust port 34 to shield the inside of the protective tube 33. In logistics sorting scenarios, dust levels are high. If dust enters the grease reservoir 21 and contaminates the grease, it will cause the grease to lose its lubricating effect, thus accelerating the wear of the bearing 14. In severe cases, it can cause the bearing 14 to seize, directly interrupting the conveying process. The addition of the rubber sheets 35 in this design is primarily to indirectly ensure stable conveying through "dust prevention and grease protection": on the one hand, the rubber sheets 35 do not affect the air pressure balance during the movement of the piston 31 (ensuring smooth lubrication); on the other hand, through elastic deformation, the exhaust port 34 is flexibly sealed, completely preventing dust from entering the grease reservoir 21 and ensuring the cleanliness of the grease. Clean grease can continuously perform its lubricating function, reducing bearing 14 wear failures and avoiding conveying jams and shutdowns caused by bearing 14 problems, providing a basic guarantee for continuous conveying.

[0026] Furthermore, each electromagnet 37 consists of at least two electromagnetic coils arranged side-by-side along the running direction of the suspension frame 12. After the electromagnetic coils are synchronously energized, an electromagnetic repulsion area with a length of 0.5-1.0m along the running direction will be formed in the running path of the suspension frame 12. The electromagnetic repulsion is generated by the electromagnetic coils and permanent magnets 32 with the same pole facing each other after being energized. High-speed movement of the suspension frame 12 is the norm for sorting and conveying. If lubrication is insufficient, the bearing 14 will experience increased running resistance and overheating due to increased friction, which will not only affect the conveying speed but may also cause problems with the bearing 14. To address the issue of faults, this design employs a "multiple coils in parallel + 0.5-1.0m continuous operating area" approach. The core consideration is to adapt to high-speed conveying conditions and ensure sufficient lubrication. The continuous electromagnetic repulsion area extends the dwell time of the suspension frame 12 within the magnetic field, ensuring that the piston 31 can complete the preset stroke and press sufficient grease into the bearing 14. After the bearing 14 receives sufficient lubrication, the rolling resistance is significantly reduced. This ensures the stability of the suspension frame 12 during high-speed movement and prevents damage to the bearing 14 due to overheating from friction, thereby ensuring that the conveying efficiency is not reduced and the process is not interrupted.

[0027] Furthermore, the bracket, mounting shaft 13, and protective tube 33 are all made of non-magnetic materials. Due to the presence of the permanent magnet 32, if the nearby structure is made of a magnetic material, the magnetic attraction between the permanent magnet 32 ​​and the structure will cause the permanent magnet 32 ​​to move, thereby causing the piston 31 to move uncontrollably and disrupting the lubrication and grease replenishment operation. It should also be noted that the stability of active lubrication and grease replenishment directly determines the continuity of lubrication of the bearing 14. If the transmission of electromagnetic repulsion is unstable, it will lead to fluctuations in the amount of lubrication and grease replenishment, or even failure to lubricate and replenish grease, ultimately causing the bearing 14 to gradually fail due to lack of grease, affecting the conveying process. The design uses non-magnetic materials, with the core consideration being to ensure stable transmission of electromagnetic repulsion and continuous effective lubrication. Magnetic materials can attract and interfere with the magnetic field generated by the electromagnet 37, causing the electromagnetic repulsion to weaken or become disordered, making it impossible to stably drive the piston 31 for lubrication. Non-magnetic materials can avoid magnetic field interference, allowing the electromagnetic repulsion to accurately and stably drive the piston 31, ensuring effective lubrication every time the suspension frame 12 passes by. This keeps the bearing 14 in a good lubrication state at all times, fundamentally avoiding bearing 14 failure due to interruption of lubrication and ensuring the continuity of the conveying process.

[0028] Furthermore, the inner diameters of channel 23, output hole 24, and input hole 25 are the same, ranging from 2.0 to 4.0 mm. Uneven lubrication of bearing 14 can lead to increased local wear, shorten service life, increase downtime maintenance frequency, and directly affect conveying efficiency. This design unifies the inner diameters of the three and limits the size range. The core consideration is to extend the life of bearing 14 and reduce maintenance downtime through "uniform and controllable lubrication and grease replenishment": the same inner diameter can avoid problems such as sudden changes in resistance during the flow of grease, ensuring that the grease enters the annular gap of bearing 14 evenly and smoothly, achieving uniform lubrication of bearing 14 around its entire circumference; the size range of 2.0-4.0 mm balances "lubrication and grease replenishment efficiency" and "avoiding waste" - ensuring that enough grease enters bearing 14 per unit time to meet the lubrication requirements during high-speed conveying, while avoiding grease overflow and waste due to excessive inner diameter. At the same time, it can extend the effective lubrication cycle after a single lubrication and grease replenishment, reduce the number of maintenance times, and indirectly improve conveying efficiency.

[0029] Working principle: The core objective of this overhead conveyor for logistics sorting is to achieve stable, continuous, and efficient sorting and transport of goods. The active lubrication system is the key support for ensuring this objective—by precisely and actively lubricating bearing 14, it prevents conveying interruptions caused by bearing 14 wear due to lack of grease, jamming, or other malfunctions. Ultimately, it achieves the collaborative logic of "lubrication and grease protection for smooth transport." The workflow of each component is as follows: 1. Core Conveying Drive Process: The drive component is the power core of the conveying function. After the motor 44 starts, it drives the drive chain 45 to circulate through the sprocket 43. With the assistance of the support arm 46, the drive chain 45 and the traction chain 41 always maintain stable engagement, thereby pulling all the suspension frames 12 to rotate and move at a uniform speed along the suspension rail 11 to complete the suspended sorting and conveying of goods. In this process, the bearing 14, as the core bearing rolling component between the suspension frame 12 and the suspension rail 11, directly determines the smoothness and continuity of the conveying.

[0030] 2. Active Lubrication and Grease Replenishment System: To prevent insufficient grease in bearing 14 from affecting the conveying process, when the suspension frame 12 moves with the traction chain 41 to the area of ​​action of electromagnet 37, the active lubrication and grease replenishment system is activated simultaneously. After the electromagnet 37 is energized, it forms a common pole with the permanent magnet 32, and the resulting electromagnetic repulsion pushes the piston 31 to slide in the grease reservoir 21, precisely pressing the grease into the inner and outer ring gaps of bearing 14 through the output hole 24, the support ring 22 channel 23, and the input hole 25. Sufficient grease can reduce the rolling friction resistance of bearing 14, reduce wear, and avoid problems such as the suspension frame 12 running stuck and the traction chain 41 being unevenly stressed due to bearing 14 jamming. This ensures that the conveying process is not interrupted from the root. Furthermore, depending on actual needs, the grease in the grease reservoir 21 can be replenished into bearing 14 in several batches or all at once.

[0031] The above-mentioned adjustment of the working intensity of electromagnet 37 can control the magnitude of electromagnetic repulsion, thereby achieving flexible adjustment of piston 31 movement stroke and lubrication amount, or controlling the speed or number of times the suspension frame 12 passes through the area of ​​action of electromagnet 37, and adjusting the replenishment amount (specific control data such as electromagnetic repulsion and electromagnet 37 start-up time need to be obtained by the staff through multiple experiments based on actual equipment).

[0032] 3. Replenishing grease in grease reservoir 21: Preparation: Prepare in advance lubricating grease compatible with bearing 14 (such as polyurea grease to meet the high-speed and heavy-load working conditions of the overhead conveyor bearing 14), special wrench, cleaning cloth and other tools to ensure that the operating environment is free of a lot of dust and to avoid contamination of the lubricating grease during the replenishment process.

[0033] Disassemble the protective tube 33: Use a special wrench to unscrew the protective tube 33 that is threaded to the end of the mounting shaft 13 away from the suspension rail 11. During the disassembly process, the coaxiality of the protective tube 33 and the mounting shaft 13 must be maintained to avoid bumping the connection structure between the permanent magnet 32 ​​and the piston 31, so as to ensure smooth movement after the subsequent reassembly of the components.

[0034] Remove piston 31 and permanent magnet 32: After the protective tube 33 is disassembled, directly remove the permanent magnet 32, which is fixedly connected to piston 31, from the port of grease reservoir 21. Simultaneously drive piston 31 to slide along the inner wall of grease reservoir 21 until it is completely removed. After removal, wipe the outer wall of piston 31 and the inner wall of grease reservoir 21 with a cleaning cloth to remove residual grease and a small amount of impurities, ensuring internal cleanliness.

[0035] Filling with grease: Slowly inject the prepared grease through the port of the grease reservoir 21. During the injection process, gently tap the outer wall of the mounting shaft 13 to ensure that the grease is evenly filled into the grease reservoir 21 and avoid air bubbles (air bubbles will cause the amount of grease added in a single lubrication to be unstable, affecting the lubrication effect of the bearing 14). The filling amount should be 90%-95% of the volume of the grease reservoir 21, leaving a small amount of space for volume compensation when the piston 31 is compressed.

[0036] Reinstall piston 31, permanent magnet 32 ​​and protective tube 33: Reinstall the cleaned piston 31 into grease reservoir 21, ensuring smooth sliding between piston 31 and inner wall of grease reservoir 21. Then thread the protective tube 33 to the mounting shaft 13 and tighten it to ensure that the protective tube 33 is securely installed without any looseness or gaps.

[0037] Functional verification: When the suspension bracket 12 moves to the area of ​​action of the electromagnet 37, observe whether the piston 31 moves normally after the electromagnet 37 is energized, and whether the grease can be smoothly pressed into the bearing 14 through the output hole 24, channel 23, and input hole 25. If the lubrication and grease replenishment is normal, it means that the grease replenishment is complete, and the active lubrication and grease replenishment system can continue to ensure the stable conveying of the conveyor.

[0038] 4. Auxiliary protection process: The protective pipe 33 and the exhaust port 34 rubber sheet 35 form a double protection, which not only ensures the smooth movement of the piston 31 through air pressure balance (ensuring stable lubrication and grease replenishment), but also prevents dust in the sorting environment from entering the grease storage chamber 21 and contaminating the lubricating grease. Clean lubricating grease can prevent abrasive particles from aggravating the wear of the bearing 14, further extending the service life of the bearing 14, reducing maintenance downtime, and indirectly improving conveying efficiency.
