Technical Field
[0001] This utility model belongs to the technical field of logistics sorting equipment, specifically relating to an end-unit externally expanded swing wheel sorting machine. Background Technology
[0002] Against the backdrop of the booming development of the modern logistics and express delivery industry, the efficiency, accuracy, and stability of cargo sorting have become key factors. Traditional swing wheel sorting machines have gradually revealed a series of problems and limitations during long-term application.
[0003] Firstly, regarding the layout of the balance wheels, traditional balance wheel sorters typically employ a relatively uniform spacing between the balance wheel units. This makes it difficult to optimize the distance between the balance wheel units at both ends and the edge of the sorter. In actual goods sorting, goods are prone to jamming near the edge, severely impacting the smoothness and efficiency of sorting. Furthermore, when faced with the need for balance wheel sorters of different sizes, the lack of a flexible end balance wheel unit spacing adjustment mechanism makes it difficult to achieve consistency between the end balance wheels and the edge distance while maintaining the balance wheel unit size and most of the spacing unchanged. This poses a significant challenge to the diversified design of balance wheel sorters, making it difficult to adapt well to the size requirements of various conveyor lines in express delivery sorting sites, thus limiting its application range in complex logistics scenarios.
[0004] Secondly, regarding the drive and control of the balance wheel, the drive structure of traditional balance wheel sorting machines is often not compact enough, resulting in a large overall size and low energy efficiency. In controlling the drop trajectory and position of packages, the lack of precise and efficient drive components makes high-precision control difficult, easily leading to drop deviations. This increases the workload of subsequent manual correction or secondary sorting, reducing the overall sorting accuracy.
[0005] Finally, the performance of rotating components is also a weak point in traditional swing wheel sorters. In traditional designs, the frictional resistance at the shaft and swing arm is relatively high. This not only reduces the response speed of the swing wheel's left and right swing, making the sorting action less agile, but also, during long-term operation, the high resistance easily leads to accelerated wear of components, increasing the equipment's failure rate and maintenance costs. Frequent downtime for maintenance seriously affects the continuity and timeliness of logistics sorting. Summary of the Invention

This makes the design of balance wheel sorting machines of different sizes more convenient, thereby adapting to the size requirements of the conveyor line at the express sorting site.
[0023] 2. This utility model arranges the balance wheel units in a diamond pattern and groups them into two balance wheel queues. All balance wheel units in the two balance wheel queues of the same group are driven by the same set of oscillating power components based on servo motors.

[0037] Cover plates 1-3 are fixedly mounted on mounting base plate 1-2 at intervals; cover plates 1-3 have downward-folding flanges around their perimeter. The bottom edge of the flanges is close to the perimeter of the top surface of mounting base plate 1-2. The top surface of cover plate 1-3 is square, and its four edges are respectively connected to one input conveyor belt and three output conveyor belts. The side length of cover plate 1-3 is equal to the width of the connected input and output conveyor belts.
[0038] Multiple swing conveyor modules 2 are arranged sequentially along the length of cover plate 1-3; each swing conveyor module 2 includes a swing power component 2-1, a reset detection component, and two swing wheel queues; each swing wheel queue includes multiple swing wheel units 2-2 arranged sequentially along the width of base 1.
[0039] like Figure 2 and Figure 3 As shown, the balance wheel unit 2-2 includes a connecting sleeve 2-2-1, a bearing 2-2-2, a rotating shaft 2-2-3, a mounting base 2-2-4, an electric roller 2-2-5, and a support plate 2-2-6. The connecting sleeve 2-2-1 is fixed in a mounting hole on the mounting base 1-2. The central hole axis of the connecting sleeve 2-2-1 is vertically aligned, and bearings 2-2-2 are embedded at both its upper and lower ends. The connecting sleeve 2-2-1 and the rotating shaft 2-2-3 are rotatably connected via bearings 2-2-2. The bottom of the mounting base 2-2-4 is fixed to the top of the rotating shaft 2-2-3. The mounting base 2-2-4 is U-shaped. The two ends of the fixed shaft of the electric roller 2-2-5 are respectively embedded in the two vertical side plates of the mounting base 2-2-4.

[0040] In the same balance wheel array, the two balance wheel units 2-2 located at both ends are called end balance wheel units 2-2, and the remaining balance wheel units 2-2 are called middle balance wheel units 2-2; the distance between two adjacent middle balance wheel units 2-2 is a preset middle wheel interval value L1; the distance between an end balance wheel unit 2-2 and its adjacent middle balance wheel unit 2-2 is the end wheel interval value L2; the end wheel interval value L2 is greater than the middle wheel interval value L1.
[0041] The two pendulum wheel queues are designated as the first pendulum wheel queue and the second pendulum wheel queue. The number of pendulum wheel units 2-2 in the first pendulum wheel queue is one less than the number of pendulum wheel units 2-2 in the second pendulum wheel queue. The pendulum wheel units 2-2 in the first pendulum wheel queue and the pendulum wheel units 2-2 in the second pendulum wheel queue are arranged alternately, forming a diamond-shaped arrangement of the oscillating conveyor modules 2.

The edge spacing value L3 is selected to avoid goods getting stuck at the edge of the cover plate 1-3. The value of the end wheel spacing value L2 can be determined according to the side length of the cover plate 1-3. By adjusting the end wheel spacing value L2, the edge spacing value L3 can be met on cover plates 1-3 of different sizes without affecting the diameter R of the balance wheel unit 2-2 and the middle wheel spacing value L1. In this embodiment, the middle wheel spacing value L1 is 2mm; the end wheel spacing value is 14mm. The edge spacing value L3 is less than or equal to 175mm; in some other embodiments, the edge spacing value L3 can also be other values in the range of 150mm to 200mm.
[0043] The swing power assembly 2-1 includes a drive rod 2-1-1, a linkage beam 2-1-2, a connecting piece 2-1-3, a swing arm 2-1-4, and a swing motor 2-1-5.

The number of swing arms 2-1-4 is equal to the number of pendulum wheel units 2-2 in the same swing conveying module 2, and they correspond one-to-one. One end of the swing arm 2-1-4 is fixed to the bottom end of the rotating shaft 2-2-3 in the corresponding pendulum wheel unit 2-2. The other end of the swing arm 2-1-4 is rotatably connected to the connecting hole on the corresponding linkage beam 2-1-2 via a bushing. The swing motor 2-1-5 is fixed to the bottom surface of the mounting base plate 1-2; the inner end of the drive rod 2-1-1 is fixed to the output shaft of the swing motor 2-1-5. The outer end of the drive rod 2-1-1 is rotatably connected to the connecting hole on one of the linkage beams 2-1-2 via a bushing.
[0044] The reset detection assembly includes a contact 2-3 and a reset sensor. The contact 2-3 is fixed to one of the linkage beams 2-1-2. The reset sensor is fixed to the bottom surface of the mounting base 1-2. The contact 2-3 moves along the path of the linkage beam 2-1-2, passing through the detection section of the reset sensor. This allows the reset sensor to be triggered when the contact 2-3 passes by, thereby calibrating the accumulated error of the swing motor 2-1-5. The reset sensor is either an infrared sensor or a Hall effect sensor.
[0045] In some embodiments, the rotating shaft adopts a hollow routing design, and the bottom outer circle and the swing arm are positioned by interference fit, combined with set screws and snap rings. By reasonably designing the length of the swing arm and designing a suitable size contact piece for the origin positioning part, the usable positioning range is increased, and the left and right swing angle of the roller can reach about ±85°.
[0046] In some embodiments, the number of cover plate screws is reduced, the connection structure of each module is simplified, and more support column connection forms are adopted, making disassembly and maintenance easier; the side plate is equipped with a handle, the bottom mesh adopts a segmented structure, and the bottom mesh hanging ears adopt an open quick-release form, which effectively reduces the disassembly time during maintenance; the roller driver in the control drive module 3 is built into the machine body through a hanging plate, which facilitates the inspection and maintenance of the roller system.
[0047] The working principle of this utility model is as follows:
[0048] The four edges of the cover plate 1-3 are respectively used as an input side and three output sides; the goods are fed into the cover plate 1-3 from the input side by the conveyor belt; each swing wheel unit 2-2 drives the goods to move; at the same time, the swing power component 2-1 in the swing conveyor module 2 drives the vertical axis of each swing wheel unit 2-2 to rotate, adjusting the direction of movement of the goods, so that the goods are output from the corresponding output side.
