Description

Technical Field

[0001] This application relates to the field of sorting machine technology, and in particular to a logistics swing wheel sorting machine. Background Technology

[0002] A balance wheel sorting machine is an automated sorting device primarily used in logistics and manufacturing. It achieves efficient and precise sorting of goods through the rotational power of a balance wheel. Its main components include a precision balance wheel, a drive system, an intelligent control system, and a high-efficiency conveying system. Guided by a preset program, the balance wheel sorting machine can flexibly respond to different sorting needs, accurately delivering items from the assembly line to designated locations.

[0003] Chinese patent CN217228942U discloses an ultra-high-speed swing wheel sorting machine, which adopts a pure electric roller drive structure and further realizes modular design in the module structure, thereby achieving ultra-high-speed conveying and sorting operations, effectively solving the problem of stalling of small items and soft packages and improving sorting efficiency. The ultra-high-speed swing wheel sorting machine includes a frame assembly, on which a sorting component, a connecting rod assembly, and a motor assembly that drives the sorting component to reciprocate along its longitudinal direction are mounted. The sorting component has a mounting plate mounted on the base frame, on which several sorting modules are arranged in multiple rows and columns. The sorting module has a fixed seat mounted on the mounting plate, and the roller support is connected to the rotating shaft by bolts. The two ends of the central shaft of the electric roller are mounted on the roller support. The module cover plate is connected to the roller support by countersunk screws. The connecting rod assembly includes interconnected T-blocks and connecting rods.

[0004] Regarding the aforementioned technologies, existing technologies utilize a motor-driven steering roller bracket to change the angle of the electric roller, thereby adjusting the conveying direction of the goods. However, existing technologies directly utilize the electric roller to contact the goods, resulting in a line contact. This leads to a small contact area, necessitating the use of a larger number of electric rollers to ensure that more rollers are in line contact with the goods, thus guaranteeing that the goods can change their direction of travel in a timely manner through friction. This increases the number of electric rollers and corresponding components required, thereby raising the manufacturing cost of the swing wheel sorting machine. Summary of the Invention

[0005] In order to reduce the manufacturing cost of the swing wheel sorting machine, this application provides a logistics swing wheel sorting machine.

[0006] This application provides a logistics swing wheel sorting machine using the following technical solution: A logistics sorting machine with a swing wheel includes a frame, on which a plurality of steering seats are rotatably connected, arranged in several rows. A steering assembly is provided on the frame to drive the steering seats to rotate. An electric roller is rotatably connected to each steering seat. A plurality of output rollers and drive rollers are also rotatably connected to each steering seat. The drive rollers abut against the surface of the electric rollers, and the output rollers abut against the surface of the drive rollers. The highest point of each output roller is located outside the top wall of the steering seat. A cover plate is provided at the top of the frame, and a first circular groove is formed on the cover plate corresponding to the position of the steering seat.

[0007] By adopting the above technical solution, during turning, the electric roller is activated, causing the drive roller to rotate, which in turn drives several output rollers to rotate synchronously. When moving goods pass through the sorting machine, the turning assembly causes the same row of turning seats to rotate synchronously, driving the output rollers to rotate. When the goods move to the sorting machine, they rub against the output rollers, eliminating the inertia of the goods and driving them to move in the direction of rotation of the output rollers, thus achieving the effect of sorting goods. The tensioning assembly drives the electric roller to press against the drive roller, allowing the drive roller to rotate smoothly. Through friction, all output rollers rotate synchronously. Within a unit of time, the friction between the goods and several output rollers on one turning seat more easily eliminates the inertia of the goods. Compared with the existing technology, fewer turning seats can be set in the overall frame, reducing the number of electric rollers and corresponding parts to be manufactured, and lowering the manufacturing cost of the logistics swing wheel sorting machine.

[0008] Optionally, the steering seat is provided with a tensioning assembly, which includes a tension spring, a fixed column, and a support block. Several fixed columns are vertically connected on both sides of the steering seat. The support block is slidably fitted between several fixed columns. The tension spring is sleeved on the fixed column and located between the support block and the steering seat. The electric roller is installed between two of the support blocks.

[0009] By adopting the above technical solution, when tensioning the electric roller and the drive roller, the tensioning spring applies pressure to the support block, causing the support block to move and driving the electric roller to move, so that the electric roller presses against the drive roller, reducing the possibility of slippage when the drive roller rotates, and achieving the effect of tensioning the electric roller and the drive roller.

[0010] Optionally, the steering assembly includes a steering motor, a drive rod, a linkage rod, and a swing rod. A rotating shaft is connected to the steering seat, and the steering seat is rotatably connected to the frame via the rotating shaft. One end of the swing rod is connected to the bottom of the rotating shaft, and the linkage rod is rotatably connected to the other end of the swing rod in the same row. The steering motor is mounted on the frame, and one end of the drive rod is connected to the output shaft of the steering motor, while the other end is rotatably connected to the linkage rod.

[0011] By adopting the above technical solution, when turning, the steering motor is started, causing the drive rod to swing, which in turn moves the linkage rod, causing all the swing rods to swing synchronously, causing the rotating shaft to rotate and the steering seat to rotate, thereby adjusting the rotation direction of the output roller and achieving the effect of turning the direction of cargo conveying.

[0012] Optionally, the steering seats in two adjacent rows are staggered.

[0013] By adopting the above technical solution, the existing technology distributes the roller supports evenly in both the horizontal and vertical directions. This results in a relatively large gap between the four roller supports, which necessitates a greater number of roller supports on the frame to ensure timely turning and movement of goods, thus increasing the manufacturing cost of the sorting machine. The staggered arrangement of adjacent rows of steering seats compensates for the gaps between the four steering seats. Compared to the existing technology, this reduces the number of steering seats on the frame while maintaining a specified distance between adjacent steering seats, thereby lowering the manufacturing cost of the sorting machine.

[0014] Optionally, a support base is rotatably connected to the frame, and a support roller is rotatably connected to the support base. The highest point of the support roller is flush with the highest point of the output roller. A swing rod is also rotatably connected between the support base and the linkage rod. A second circular groove is provided on the cover plate at the position corresponding to the support base.

[0015] By adopting the above technical solution, because the adjacent rows of steering seats are staggered, the distance between the row of steering seats and the side wall of the frame is larger, which easily causes sliding friction between the goods and the cover plate, affecting the turning and conveying of the goods. By setting support seats and support rollers, the goods are made to roll against the support rollers, reducing the impact on the turning and conveying of the goods.

[0016] Optionally, a fixing frame is connected to the cover plate at a position corresponding to the position between the support seat and the steering seat, a support head is rotatably connected to the fixing frame, and a round hole is opened on the cover plate at a position corresponding to the support head.

[0017] By adopting the above technical solution, the support head is used to assist in supporting the goods, reducing the possibility of friction between the moving goods and the cover plate at the position between the support roller and the output roller, and ensuring that the goods can move smoothly when turning.

[0018] Optionally, the steering seats are provided in five rows, and a connecting rod is rotatably connected between the linkage rods of adjacent rows of steering seats.

[0019] By adopting the above technical solution, the linkage rods of two adjacent rows of steering seats are connected by a connecting rod, so that one motor controls the synchronous steering movement of two rows of steering seats, and the remaining row of steering seats is controlled by a single machine, reducing the manufacturing cost of the device.

[0020] Optionally, two first steering wheels are rotatably connected to the rotating base, a fixed wheel is coaxially connected to the electric drum, and a transmission belt is wound between the output roller, the fixed wheel and the first steering wheels.

[0021] By employing the above technical solution, the electric roller, drive roller, and output roller rotate through friction. However, when heavy goods pass over the sorting machine, the drive roller is prone to slippage, preventing the sorting machine from effectively transporting goods. By installing a transmission belt, an additional layer of friction protection is provided between the output roller, drive roller, and electric roller, reducing the possibility of slippage between the output roller and drive roller.

[0022] Optionally, two second steering wheels are rotatably connected to the steering seat. The second steering wheels are located above the first steering wheel, and the transmission belt is wound around the second steering wheels and passes through the upper half turn of the fixed wheel.

[0023] By adopting the above technical solution and setting a second steering wheel to change the position of the transmission belt passing over the fixed wheel, the tensioning component also acts on the transmission belt, reducing the transmission belt slippage phenomenon.

[0024] Optionally, the transmission roller is a rubber roller, and the surface of the transmission roller is provided with several anti-slip stripes.

[0025] By adopting the above technical solution and setting rubber rollers and anti-slip stripes, the friction between the electric roller and the drive roller and between the drive roller and the output roller is increased, further reducing the slippage phenomenon of the drive roller and the output roller.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. During the turning process, the electric roller is activated, causing the drive roller to rotate and driving several output rollers to rotate synchronously. When moving goods pass through the sorting machine, the turning assembly causes the same row of turning seats to rotate synchronously, driving the output rollers to rotate. When the goods move to the sorting machine, they rub against the output rollers, eliminating the inertia of the goods and driving them to move in the direction of the output rollers' rotation, thus achieving the effect of sorting the goods. The tensioning assembly drives the electric roller to press against the drive roller, allowing the drive roller to rotate smoothly. Through friction, all output rollers rotate synchronously. Within a unit of time, the friction between the goods and several output rollers on one turning seat more easily eliminates the inertia of the goods. Compared with existing technologies, fewer turning seats can be set in the overall frame, reducing the number of electric rollers and corresponding parts required, and lowering the manufacturing cost of the logistics swing wheel sorting machine.

[0037] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0038] Embodiment 1 of this application discloses a logistics swing wheel sorting machine. (Refer to...) Figure 1 and Figure 2 The logistics wheel sorting machine includes a frame 1, which is rectangular in shape. Several steering seats 2 are arranged on the frame 1, and the steering seats 2 are divided into several rows. In this embodiment, five rows are used as an example, and adjacent rows of steering seats 2 are staggered. A rotating shaft is fixedly connected to the bottom of the steering seat 2, and the steering seat 2 is rotatably connected to the frame 1 through the steering shaft.

[0039] Refer to 3 and Figure 4The steering seat 2 is equipped with an electric roller 21, several drive rollers 22 and output rollers 23. In this embodiment, two drive rollers 22 and four output rollers 23 are provided. The two drive rollers 22 and the four output rollers 23 are rotatably connected to the steering seat 2. The drive rollers 22 abut against the electric roller 21 and the output rollers 23, and the output rollers 23 are partially located outside the top wall of the steering seat 2.

[0040] Reference Figure 3 A tensioning assembly 3 is provided on the steering seat 2, which includes a tension spring 31, a fixed column 32, and a support block 33. Several fixed columns 32 are vertically fixedly connected to both sides of the steering seat 2; in this embodiment, two columns are used as an example. The support block 33 is slidably fitted between the two fixed columns 32. The tension spring 31 is sleeved on the fixed column 32 and located between the support block 33 and the steering seat 2. An electric roller 21 is rotatably connected between the two support blocks 33 and abuts against the drive roller 22, which is a rubber cylinder. The rotation of the electric roller 21 causes the two drive rollers 22 to rotate, thereby causing the four output rollers 23 to rotate synchronously.

[0041] Reference Figure 1 and Figure 5 On the frame 1, a smaller row of steering seats 2 are rotatably connected to the side wall of the frame 1 via a rotating shaft, with support seats 11 rotatably connected to support rollers 12. The highest point of the support rollers 12 is flush with the highest point of the output rollers 23. On the frame 1, a fixing frame is bolted to the position between the support seats 11 and the steering seats 2. A support head 13 is rotatably connected to the fixing frame, and the support head 13 is used to assist in supporting the goods.

[0042] Reference Figure 1 and Figure 2 A cover plate 14 is bolted to the frame 1, covering the top of the frame 1. The cover plate 14 is provided with several first circular grooves, second circular grooves and circular holes. The first circular grooves correspond to the steering seat 2, the second circular grooves correspond to the support seat 11, and the circular holes correspond to the support head 13. The cover plate 14 is used to prevent impurities from entering the sorting machine.

[0043] Reference Figure 6 and Figure 7The frame 1 contains three sets of steering assemblies 4, each including a steering motor 41, a drive rod 42, a linkage rod 43, and a swing rod 44. One end of the swing rod 44 is fixedly connected to a rotating shaft, and the linkage rod 43 is rotatably connected to the other end of all the swing rods 44 in the same row. The steering motor 41 is installed in the frame 1 below the corresponding steering seat 2. One end of the drive rod 42 is fixedly connected to the output shaft of the steering motor 41, and the other end is rotatably connected to the linkage rod 43. Furthermore, connecting rods rotatably connect adjacent rows of linkage rods 43, allowing one steering motor 41 to simultaneously drive two rows of linkage rods 43. The remaining linkage rod 43 is driven by a single steering motor 41.

[0044] When sorting goods, the adjustment roller is started, causing the drive roller 22 to rotate, and the four output rollers 23 to rotate synchronously. Then, the steering motor 41 is started, causing the other end of the drive rod 42 to swing, which drives the linkage rod 43 to move. The drive rod 42 swings, causing the swing rod 44 to swing, which drives the rotating shaft to rotate, thereby adjusting the rotation direction of the output rollers 23. The moving goods pass through the output rollers 23 and are rubbed against the output rollers 23 to change direction and move, thus achieving the effect of sorting goods.

[0045] The implementation principle of a logistics swing wheel sorting machine according to an embodiment of this application is as follows: When turning the goods, the electric roller 21 is started, causing the output roller 23 to rotate. When the moving goods approach the sorting machine, the steering motor 41 is started, causing the drive rod 42 to swing, the linkage rod 43 to move, and driving the swing rod 44 in the same row to swing synchronously, causing the rotating seat to rotate, thereby adjusting the rotation direction of the output roller 23. When the goods move onto the output roller 23, the inertia of the goods movement is first quickly eliminated through friction, and then the goods move with the rotation direction of the output roller 23, thus realizing the effect of the sorting machine sorting goods of different heights.

[0046] The tensioning assembly 3 drives the electric roller 21 to press against the transmission roller 22, so that the transmission roller 22 rotates smoothly. Through friction, all output rollers 23 rotate synchronously. In a unit of time, the friction between the goods and several output rollers 23 on a steering seat 2 can more easily eliminate the inertia of the goods. Compared with the prior art, a smaller number of steering seats 2 can be set in the overall frame 1, reducing the number of electric rollers 21 and corresponding parts to be prepared, and reducing the manufacturing cost of the logistics swing wheel sorting machine.

[0047] Example 2: The difference between this example and Example 1 is that a structure is added between the electric roller 21, the drive roller 22 and the output roller 23 to further reduce the slippage of the drive roller 22 or the output roller 23.

[0048] Reference Figure 8 and Figure 9The steering seat 2 has a first steering wheel 24 and a second steering wheel 25 rotatably connected to opposite sides. There are two of each of the first steering wheel 24 and the second steering wheel 25, and the second steering wheel 25 is located between the first steering wheel 24 and the electric roller 21. A fixed wheel 211 is fixedly connected to the electric roller 21. A transmission belt 15 is sleeved between the output roller 23, the first steering wheel 24, the fixed wheel 211, and the second steering wheel 25. The transmission belt 15 passes through the upper half of the fixed wheel 211.

[0049] Reference Figure 8 and Figure 9 By setting up a transmission belt 15, auxiliary friction is added between the output roller 23, the transmission roller 22 and the electric drum 21, thereby reducing the slippage of the output roller 23 or the transmission roller 22.

[0050] Reference Figure 8 and Figure 9 To further reduce slippage of the output roller 23 or the drive roller 22, the drive roller 22 is a rubber roller with several anti-slip stripes 221 on its surface, evenly distributed axially around the axis of the drive roller 22. The rubber roller and the anti-slip stripes 221 increase the friction between the output roller 23 and the drive roller 22, and between the drive roller 22 and the electric drum 21.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
