Description

Technical Field

[0001] This invention relates to the field of automated warehouse transportation and sorting, and specifically to a swing wheel sorting conveyor with a buffer function. Background Technology

[0002] Swing wheel sorting conveyors are commonly used material sorting and conveying equipment in automated warehouses and warehousing logistics systems. They achieve straight-line conveying and lateral sorting of materials through the rotation and direction of the swing wheels. They are characterized by high sorting efficiency and flexible layout, and are widely used in e-commerce express delivery, manufacturing, food distribution and other scenarios.

[0003] In conventional swing wheel sorting conveyors, the swing wheel units are mostly rigidly fixed, resulting in rigid contact impacts when materials fall onto the swing wheel's working surface and during the sorting process. For fragile or thin-walled packaged materials, these hard impacts can easily cause packaging deformation or even damage to the contents. Long-term material impacts can also accelerate the wear of the swing wheel's internal bearings and supports, while also generating significant noise during equipment operation.

[0004] Most rotary sorting machines use fixed baffles on the inlet side to straighten materials. However, misaligned materials slide rigidly against the baffles, easily leading to damage to packaging corners and jamming. For materials of different widths, manual adjustment of the distance between the baffles on both sides is required, which is cumbersome and insufficiently adaptable to scenarios involving mixed sorting of multiple material sizes. Furthermore, when materials from the upstream high-speed conveyor directly enter the sorting area, excessive relative speed can cause sorting positioning deviations, affecting sorting accuracy.

[0005] Therefore, there is a need to provide a swing wheel sorting conveyor with a buffer function to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a swing wheel sorting conveyor with a buffer function.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a swing wheel sorting conveyor with a buffer function, comprising a swing wheel conveyor housing, a swing wheel housing and a motor, wherein the swing wheel housing and the motor are both disposed inside the swing wheel conveyor housing, a drive assembly is disposed on the outside of the swing wheel conveyor housing, a floating assembly is disposed on the swing wheel housing, and a straightening assembly is disposed on the drive assembly; The drive assembly includes a hollow block, which is fixedly connected to the outer wall of the swing wheel conveyor housing. Rectangular positioning blocks are symmetrically arranged inside the hollow block. Umbrella-shaped grooved disks are rotatably connected inside the two rectangular positioning blocks. Rotating rods are slidably connected in the grooves on the end faces of the two umbrella-shaped grooved disks. The straightening component includes two positioning plates, which are symmetrically slidably connected to the top of the hollow block. A straightening wheel set is slidably connected to the top of each of the two positioning plates, and a sliding plate is slidably connected inside each of the two positioning plates.

[0008] Preferably, the driving component includes a limiting strip group, which is fixedly connected to the top of the rectangular positioning block. A slider group is slidably connected inside the limiting strip group. A T-shaped rod is snapped onto the upper surface of one end of the slider group, and a connecting block is snapped onto the upper surface of the other end of the slider group.

[0009] Preferably, the rotating rod is rotatably connected inside the T-shaped rod.

[0010] Preferably, the straightening component includes two sets of distance-extending plate groups, which are respectively fixedly connected to two positioning plates, and distance-extending blocks are fixedly connected to the side of each of the two sliding plates away from the positioning plates.

[0011] Preferably, the straightening component includes two lead screws, which are rotatably connected to two sets of distance-increasing plates, and are threadedly connected to the inside of the distance-increasing block.

[0012] Preferably, the centering wheel assembly is fixedly connected to the skateboard.

[0013] Preferably, the straightening component includes a damping plate, which is fixedly connected to the top of the hollow block.

[0014] Preferably, the drive assembly includes a drive belt that is drively connected to the motor and two umbrella-shaped grooved discs.

[0015] Preferably, the floating component includes a vertical slide groove, which is formed on the outer wall of the balance wheel housing. A rectangular slider group is slidably connected inside the vertical slide groove. A sliding rod is symmetrically fixed to the bottom of the rectangular slider group. The sliding rod is slidably connected to the bottom of the vertical slide groove. A drive wheel is engaged at the top of the rectangular slider group.

[0016] Preferably, a return spring is sleeved on the outer wall of the slide bar, one end of the return spring is fixedly connected to the rectangular slider assembly, and the other end of the return spring is fixedly connected to the balance wheel housing.

[0017] The present invention provides a swing wheel sorting conveyor with a buffer function. Compared with the prior art, the advantages of the present invention are: By adopting a synchronous reciprocating dynamic straightening structure, relying on the original motor of the equipment for power, the material is straightened by the synchronous reciprocating push of the straightening wheel sets on both sides. Compared with the fixed baffle straightening structure, it can reduce the hard impact damage between the material and the straightening structure, and can adapt to different specifications of materials within a certain width range without the need for manual adjustment of the spacing, thus improving the sorting adaptability and operation efficiency of the equipment.

[0018] With the matching height adjustment structure of the straightening wheel, the effective working height of the straightening wheel assembly can be adjusted by rotating the screw, so that the straightening action point matches the center of gravity position of materials of different heights, reducing the probability of material tipping over during the straightening process, and adapting to the sorting needs of various packaging forms such as boxes, bags, and cartons.

[0019] By installing a damping plate deceleration structure at the sorting inlet, the conveying speed of materials entering the sorting area can be reduced, minimizing sorting deviation and lateral impact caused by high-speed materials, and improving the accuracy of sorting positioning. The entire structure is purely mechanically linked, requiring no additional independent power or electrical control components. It operates stably and reliably, has low maintenance costs, and can be adapted for upgrading existing conventional swing wheel sorting equipment.

[0020] By setting up a vertically floating balance wheel buffer structure, when materials come into contact with the drive wheel, the deformation of the return spring can absorb the vertical impact force, which can reduce the risk of rigid collisions during material sorting, while also alleviating the impact load on the internal bearings of the balance wheel, reducing parts wear, reducing equipment operating noise, and extending the service life of the balance wheel unit.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0024] In the description of this invention, the terms “center,” “horizontal,” “up,” “down,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a swing wheel sorting conveyor with a buffer function, including a swing wheel conveyor housing 11, a swing wheel housing 12 and a motor 13. The swing wheel housing 12 and the motor 13 are both disposed inside the swing wheel conveyor housing 11. A drive assembly is disposed on the outside of the swing wheel conveyor housing 11. A floating assembly is disposed on the swing wheel housing 12 and a straightening assembly is disposed on the drive assembly.

[0027] It should be noted that: the pendulum conveyor housing 11 is the load-bearing frame of the whole machine, which houses multiple pendulum housings 12 arranged in an array. The outer wall provides the installation reference for the drive component and the straightening component, forming the main support structure of the sorting conveyor; the pendulum housing 12 is the support housing for a single pendulum unit. Multiple pendulum housings 12 are arranged in an array inside the pendulum conveyor housing 11, and the top surfaces of all pendulums together form the material sorting and conveying working surface; this solution adds a floating component on the basis of the pendulum housing 12 to realize the vertical buffering function of the pendulum; the motor 13 is the core power source of the whole machine, which provides power input for the material conveying rotation of the pendulum and also provides power to the drive component at the same time. There is no need to configure a separate power component for the straightening structure, which simplifies the overall structure and reduces the modification cost.

[0028] like Figure 3 As shown, a vertical groove 21 is formed on the outer wall of the balance wheel housing 12. A rectangular slider assembly 22 is slidably connected inside the vertical groove 21. A slider rod 23 is symmetrically fixed to the bottom of the rectangular slider assembly 22. The slider rod 23 is slidably connected to the bottom of the vertical groove 21. A return spring 24 is sleeved on the outer wall of the slider rod 23. One end of the return spring 24 is fixedly connected to the rectangular slider assembly 22, and the other end of the return spring 24 is fixedly connected to the balance wheel housing 12. A drive wheel 25 is engaged at the top of the rectangular slider assembly 22.

[0029] This floating balance wheel structure allows the drive wheel 25 to extend and retract vertically adaptively. When the material contacts the balance wheel, the vertical impact force is absorbed by the deformation of the return spring 24, avoiding rigid impact damage to the material packaging and the internal bearings of the balance wheel. At the same time, it can adapt to different materials within a certain weight range, reduce sorting noise, and extend the service life of the balance wheel assembly.

[0030] like Figures 4 to 8 As shown, the hollow block 31 is fixedly connected to the outer wall of the swing wheel conveyor housing 11. Rectangular positioning blocks 32 are symmetrically arranged inside the hollow block 31. Umbrella-shaped grooved discs 33 are rotatably connected inside the two rectangular positioning blocks 32. A transmission belt 39 is connected between the motor 13 and the two umbrella-shaped grooved discs 33. After the motor 13 starts, it can synchronously drive the two umbrella-shaped grooved discs 33 to rotate through the transmission belt 39.

[0031] The top of the rectangular positioning block 32 is fixedly connected to a limit strip assembly 36. A slide strip assembly 37 is slidably connected inside the limit strip assembly 36. A T-shaped rod 34 is snapped onto the upper surface of one end of the slide strip assembly 37, and a connecting block 38 is snapped onto the upper surface of the other end of the slide strip assembly 37. A rotating rod 35 is rotatably connected inside the T-shaped rod 34, and the rotating rod 35 is slidably connected in the end face groove of the umbrella-shaped grooved disk 33.

[0032] The end face of the umbrella-shaped grooved disk 33 is provided with a continuous closed curved groove, which is the core transmission component of the entire straightening structure. During the rotation of the umbrella-shaped grooved disk 33, the rotating rod 35 and the T-shaped rod 34 can be driven to make horizontal reciprocating linear motion through the groove trajectory. Then, the sliding bar group 37 drives the straightening structure on both sides to reciprocate synchronously. Only a single power input is needed to realize the synchronous straightening drive on both sides. No additional electronic control components are required, and the structure is simple and reliable.

[0033] like Figures 9 to 11 As shown, two positioning plates 41 are symmetrically slidably connected to the top of the hollow block 31. The bottom of each positioning plate 41 is fixedly connected to the connecting block 38 on the corresponding side. When the slider assembly 37 reciprocates, it can synchronously drive the two positioning plates 41 to perform reciprocating movements in opposite directions. The top of each positioning plate 41 is slidably connected to a straightening wheel assembly 42, and the inside of each positioning plate 41 is slidably connected to a sliding plate 43. The straightening wheel assembly 42 is fixedly connected to the sliding plate 43.

[0034] Two sets of spacer plates 44 are fixedly connected to the two positioning plates 41 respectively. Spacer blocks 45 are fixedly connected to the side of the slide plate 43 away from the positioning plates 41. Two lead screws 46 are rotatably connected to the two sets of spacer plates 44 respectively, and the two lead screws 46 are threaded into the interior of the spacer blocks 45. Rotating the lead screws 46 can drive the spacer blocks 45 and the slide plate 43 to slide vertically through the threaded transmission, thereby adjusting the working height of the straightening wheel set 42 to adapt to sorting materials of different heights and packaging forms, and to prevent the materials from tipping over during the straightening process.

[0035] A damping plate 47 is fixedly connected to the top of the hollow block 31. The damping plate 47 is set on the material inlet side. It can reduce the conveying speed of the material entering the sorting area through the high damping material on the surface, thereby reducing the impact and sorting deviation caused by high-speed materials.

[0036] Compared to conventional fixed baffle straightening structures, this reciprocating dynamic straightening method can gradually correct skewed or offset materials to the center of the conveying surface through synchronous flexible pushing from both sides, avoiding packaging damage and jamming caused by hard impact between materials and baffles. At the same time, it can adapt to different specifications of materials within a certain width range, and can complete the straightening without manually adjusting the baffle spacing, making the equipment more adaptable.

[0037] Before the materials to be sorted are conveyed to the swing wheel sorting area, they first pass through the damping plate 47 on the top of the hollow block 31. The damping plate 47 reduces the conveying speed of the materials through sliding friction, preventing the materials from rushing into the sorting area at high speed and improving the accuracy of subsequent sorting and positioning.

[0038] After the motor 13 starts, it drives the two umbrella-shaped grooved discs 33 to rotate inside the rectangular positioning block 32 synchronously through the transmission belt 39. The curved grooves on the end face of the umbrella-shaped grooved discs 33 drive the rotating rod 35 and the T-shaped rod 34 to perform horizontal reciprocating linear motion. The T-shaped rod 34 drives the slide bar group 37 to slide synchronously along the guide of the limit bar group 36. The other end of the slide bar group 37 drives the two side positioning plates 41 to perform synchronous reciprocating motion in opposite directions through the connecting block 38. This drives the straightening wheel group 42 to dynamically push and straighten the material on the conveying surface, so that the material is aligned with the center position of the conveying surface, avoiding sorting errors and jamming problems caused by material deviation and skew.

[0039] For sorting materials of different heights, the rotatable lead screw 46 rotates on the spacer plate assembly 44, and drives the spacer block 45 to move vertically through the threaded transmission. The spacer block 45 simultaneously drives the slide plate 43 to slide vertically along the internal groove of the positioning plate 41, adjusting the effective working height of the straightening wheel assembly 42 so that the straightening action point matches the height of the material's center of gravity, thereby improving the stability of the straightening process.

[0040] When the material is conveyed to the working surface of the drive wheel 25, the material's own weight and vertical impact force act on the surface of the drive wheel 25. The drive wheel 25 drives the rectangular slider group 22 to slide downward along the vertical slide groove 21. The slide rod 23 moves downward synchronously with the rectangular slider group 22, and synchronously compresses the return spring 24. The vertical impact of the material at the moment of contact is absorbed by the spring deformation. After the material leaves the surface of the drive wheel 25, the return spring 24 elastically extends, pushing the rectangular slider group 22, the slide rod 23 and the drive wheel 25 to return upward along the vertical slide groove 21, keeping the working surface of the swing wheel at the same height.

[0041] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments: Before the materials to be sorted enter the swing wheel sorting area, they pass through the damping plate 47 on the top of the hollow block 31. The high damping material on the surface of the damping plate 47 can reduce the conveying speed of the materials through sliding friction, prevent the materials from rushing into the sorting area at high speed, reduce the lateral impact of the materials with the swing wheel and the straightening structure, improve the accuracy of subsequent sorting and positioning, and reduce the risk of material corners being bumped and damaged.

[0042] By setting a damping plate 47 deceleration structure at the sorting inlet, the conveying speed of materials entering the sorting area can be reduced, thereby reducing sorting deviation and lateral impact caused by high-speed materials and improving the accuracy of sorting positioning.

[0043] Synchronous reciprocating correction drive steps After the motor 13 starts, it synchronously drives two umbrella-shaped grooved discs 33 to rotate inside the rectangular positioning block 32 via the transmission belt 39. The end face of the umbrella-shaped grooved discs 33 is provided with a continuous closed curved groove, and the rotating rod 35 is embedded in the curved groove. During the rotation of the umbrella-shaped grooved discs 33, the curved groove trajectory drives the rotating rod 35 and the T-shaped rod 34 to perform horizontal reciprocating linear motion. The T-shaped rod 34 drives the slide bar group 37 to perform synchronous reciprocating sliding along the guide of the limit bar group 36. The other end of the slide bar group 37 drives the two side positioning plates 41 to perform synchronous reciprocating motion in opposite directions via the connecting block 38, thereby driving the straightening wheel group 42 to dynamically push and straighten the material on the conveying surface.

[0044] Compared to conventional fixed baffle straightening structures, reciprocating dynamic straightening can gradually correct skewed or offset materials to the center of the conveying surface through synchronous flexible pushing from both sides, avoiding packaging damage and jamming caused by hard impact between materials and baffles. At the same time, it can adapt to different specifications of materials within a certain width range, and can complete the straightening of materials of different sizes without manually adjusting the baffle spacing. The equipment has stronger adaptability and the material conveying process is more stable.

[0045] Alignment height adaptive adjustment steps For sorting materials of different heights and packaging forms, the rotatable lead screw 46 rotates on the spacer plate assembly 44, and drives the spacer block 45 to move vertically through the threaded transmission. The spacer block 45 simultaneously drives the slide plate 43 to slide vertically along the internal groove of the positioning plate 41, thereby adjusting the effective working height of the centering wheel assembly 42.

[0046] This adjustment structure allows the position of the straightening wheel assembly 42 to match the height of the material's center of gravity, preventing the material from tipping over during straightening and further improving the straightening stability of materials of different specifications. It is suitable for sorting needs of various packaging forms such as boxes, bags, and cartons.

[0047] Balance wheel vertical floating buffer steps When the material is conveyed to the working surface of the balance wheel, its own weight and vertical impact force act on the surface of the drive wheel 25. The drive wheel 25 drives the rectangular slider assembly 22 to slide downward along the vertical groove 21. The slide rod 23 moves downward synchronously with the rectangular slider assembly 22, compressing the return spring 24 in sync. The spring deformation absorbs the vertical impact at the moment of material contact, preventing rigid impact damage to the material packaging and the internal bearings of the balance wheel. After the material leaves the surface of the drive wheel 25, the return spring 24 elastically extends, pushing the rectangular slider assembly 22, the slide rod 23, and the drive wheel 25 upward along the vertical groove 21 to return to their original positions, maintaining the consistent height of the balance wheel's working surface.

[0048] This floating buffer structure can adapt to materials within a certain weight range, reduce operating noise during sorting operations, extend the service life of the balance wheel assembly, and is suitable for sorting scenarios of multiple categories and large weight differences in automated warehouses. When materials come into contact with the drive wheel 25, the vertical impact force can be absorbed by the deformation of the return spring 24, which can reduce the risk of rigid collisions during material sorting, while alleviating the impact load on the internal bearings of the balance wheel, reducing wear on parts, reducing equipment operating noise, and extending the service life of the balance wheel unit.

[0049] The entire straightening and buffering structure adopts a purely mechanical linkage. The power for the straightening structure is uniformly provided by the motor 13 driven by the swing wheel, eliminating the need for additional power components and electrical control systems. The structure is compact, reliable, and has low maintenance costs. The triple structure of deceleration, straightening, and buffering works together to improve the stability of the material conveying and sorting process, reduce material breakage rate, reduce equipment operating losses, and improve the overall efficiency of conveying and sorting operations.
