Description

Technical Field

[0001] This invention relates to the technical field of logistics equipment, and in particular to a multifunctional mobile sorting device and its control method. Background Technology

[0002] With the deepening of globalization and automation, the logistics industry is facing unprecedented opportunities and challenges. Traditional logistics sorting methods are no longer sufficient to meet the demands of modern society for high-efficiency operation, making the development of mobile sorting automation technology crucial for the logistics industry's growth. Efficiency is paramount in the logistics industry.

[0003] Currently, the logistics industry inevitably uses transport vehicles to transport parcels, and sorting and classifying these parcels before transport is a necessary operation. Existing technologies typically involve sorting operations in fixed locations using machines or manually. This lack of flexibility in site selection and limited capacity to handle surges in business when space is limited is problematic. Therefore, mobile sorting platforms have enabled rapid parcel sorting during peak periods. However, existing sorting equipment with folding mechanisms and inclined conveyor belts has a fixed height, failing to dynamically adapt to the varying heights of sorting equipment on the platform. This results in a lack of balance between automation and flexibility in complex sorting scenarios. Furthermore, the bulky conveyor belts lack efficient storage technology, requiring specialized vehicles for transport, leading to high operating costs. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide a multifunctional mobile sorting device and control method, which uses a mobile sorting device to achieve rapid deployment, supports on-demand allocation to different sorting sites, and can achieve dynamic spatial adaptation with different sorting equipment heights, thereby improving the balance between automation and flexibility in complex sorting scenarios.

[0005] To achieve the above objectives, this invention discloses a multifunctional mobile sorting device, including a sorting platform, a narrow strip sorter, a package feeding conveyor belt, a lifting mechanism, and a control system. The narrow strip sorter is disposed within the sorting platform, and several sorting chutes are respectively provided on both sides of the narrow strip sorter and hinged to the sorting platform. The lifting mechanism is disposed at the head end of the narrow strip sorter, and the package feeding conveyor belt is hinged to the lifting mechanism. The lifting mechanism drives the package feeding conveyor belt to rise and fall, thereby connecting the package feeding conveyor belt with the narrow strip sorter, and packages are fed one by one onto the narrow strip sorter via the package feeding conveyor belt.

[0006] The narrow-belt sorting machine includes a machine body and several sorting trolleys. The inner wall of the machine body is provided with a rotary guide rail. The two ends of the sorting trolleys are respectively slidably engaged with the rotary guide rail. A linear motor drives the sorting trolleys to rotate along the rotary guide rail, which is used to transport the packages fed by the package supply belt conveyor to the designated sorting chute. The corresponding sorting trolleys then send the packages into the sorting chute, so that the sorting chute guides the packages onto the designated sorting line.

[0007] The narrow belt sorting machine is equipped with an inlet conveyor module at the front end, which is used to send the packages on the package supply belt conveyor into the narrow belt sorting machine. A photoelectric monitoring module is set above the inlet conveyor module to obtain the size of the package. A scanning module is also set above the inlet conveyor module to obtain the barcode information and location coordinate information of the package.

[0008] The control system is electrically connected to the narrow strip sorting machine, the package feeding belt conveyor, the lifting mechanism, and the inlet conveyor module, respectively.

The bag supply belt is fixedly connected to the lifting frame and the lifting frame drives the bag supply belt to lift and lower through the lifting drive device.

[0015] Furthermore, a tilting frame is installed below the packing conveyor belt. The two ends of the tilting frame are respectively hinged to the lifting frame, and a tilting drive device is hinged on the lifting frame. Its telescopic end is hinged to the other side wall of the tilting frame, so that the tilting drive device drives the packing conveyor belt to tilt around the lifting frame.

[0016] Furthermore, the sorting platform is provided with a base frame at its bottom, and a cavity is provided inside the base frame. The inner wall of the cavity is provided with grooves that slide and cooperate with the rollers to accommodate the transfer robot.

[0017] Furthermore, the narrow strip sorting machine is provided with fixed guide plates on both sides, and a folding guide plate is provided at the end of the fixed guide plate. The first end of the folding guide plate is hinged to the sorting platform. The surfaces of the fixed guide plate and the folding guide plate are provided with a plurality of positioning holes spaced apart along the width direction. The fixed guide plate and the folding guide plate are provided with a plurality of baffles. The bottom of the baffles has a plurality of positioning pins that match the positioning holes, so that a sorting chute is formed between the baffles.

[0018] Furthermore, the sorting trolley includes a sorting conveyor belt and a sorting carrier. The side wall of the sorting conveyor belt is snapped onto the sorting carrier. Both ends of the sorting carrier are provided with guide wheel assemblies that slide in cooperation with the rotary guide rail. The sorting carriers of the plurality of sorting trolleys are respectively hinged to each other through connecting components.

[0019] Furthermore, the rotary guide rail includes an upward guide rail, a downward guide rail, and a turning guide rail. The upward guide rail and the downward guide rail are arranged parallel to each other vertically, and the turning guide rails are a pair and are respectively arranged between the upward guide rail and the downward guide rail.

[0020] The turning guide rail includes several arc-shaped guide plates, which are stacked and fixedly mounted on the machine body. The ends of the arc-shaped guide plates are respectively connected to the upward guide rail and the downward guide rail.

[0021] Furthermore, the narrow strip sorting machine is provided with fixed guide plates on both sides, and a folding guide plate is provided at the end of the fixed guide plate. The first end of the folding guide plate is hinged to the sorting platform. The surfaces of the fixed guide plate and the folding guide plate are provided with a plurality of positioning holes spaced apart along the width direction. The fixed guide plate and the folding guide plate are provided with a plurality of baffles. The bottom of the baffles has a plurality of positioning pins that match the positioning holes, so that a sorting chute is formed between the baffles.

[0045] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 1 , Figure 14As shown, a multifunctional mobile sorting device includes a sorting platform 1, a narrow-belt sorter 2, several sorting chutes 3, a packing conveyor belt 4, a lifting mechanism 5, and a control system. The narrow-belt sorter 2 is located within the sorting platform 1. Several sorting chutes 3 are respectively located on both sides of the narrow-belt sorter 2. The lifting mechanism 5 is located at the head end of the narrow-belt sorter 2. The packing conveyor belt is hinged to the lifting mechanism 5 and is driven to rise and fall by the lifting mechanism 5, so that the packing conveyor belt 4 is connected to the narrow-belt sorter 2. The head end of the narrow-belt sorter 2 is provided with an inlet conveyor module 6, which is used to feed packages on the packing conveyor belt 4 into the narrow-belt sorter 2, so that the packing conveyor belt 4 feeds packages into the narrow-belt sorter 2 one by one. The control system is electrically connected to the narrow-belt sorter 2, the packing conveyor belt 4, the lifting mechanism 5, and the inlet conveyor module 6. In this embodiment, the control system is a programmable logic controller.

[0047] Combination Figure 2 , Figure 7 As shown, in this embodiment, the sorting platform 1 is a box structure. The bottom of the sorting platform 1 is provided with a base frame 12, which consists of an upper frame and a lower frame. The upper frame is fixedly installed at the bottom of the sorting platform 1, and the lower frame is installed at the bottom of the upper frame. Several crossbeams are provided between the lower frame and the upper frame along the width direction. In this embodiment, the crossbeams are I-beams. Reinforcing plates and reinforcing pipes are provided between the upper frame and the bottom surface of the sorting platform 1, which greatly increases the load-bearing capacity and load capacity of the sorting platform.

[0048] Reference Figure 1 , Figure 2 The sorting platform is provided with side wing plates 13 hinged to the top of both sides. A side wing drive device is hinged to the inner top surface of the sorting platform 1. In this embodiment, the side wing drive device is preferably a cylinder, and its extension end is hinged to the side wing plate 13. The side wing plate 13 is driven to flip up and down by the side wing drive device. When the side wing plate flips up, it opens the side wall of the sorting platform 1, or the side wing plate 13 flips down to close the side wall of the sorting platform 1.

[0049] A rear wing plate 14 is hinged to the top of the sorting platform 1. A rear wing drive device is hinged to the inner top surface of the sorting platform 1. In this embodiment, the rear wing plate 14 drive device is preferably a cylinder, whose telescopic end is hinged to the rear wing plate 14. The rear wing plate 14 is opened and closed by the rear wing drive device. When sorting is required, the rear wing drive device 141 flips upward to open the head of the sorting platform 1. When no work is required, it drives the rear wing plate 14 to flip downward to close the head of the sorting platform.

[0050] The above settings enable the sorting platform 1 to be further expanded and greatly reduce the space occupied by the sorting platform.

[0051] Combination Figure 3 , Figure 4As shown, the lifting mechanism 5 further includes a pair of lifting frames 51 and a pair of lifting drive devices 52. Fixed frames 11 are respectively provided on both sides of the front end of the sorting platform 1. Slide grooves are provided on the inner side of the fixed frames 11. Guide wheels that slide in cooperation with the slide grooves 52 are rotatably provided on the side wall of the lifting frame 51, so that the lifting frame 51 is slidably disposed in the fixed frame 11. The lifting drive devices 52 are respectively fixedly installed on the lower part of the fixed frame 11. In this embodiment, the lifting drive device 52 is preferably a cylinder, and its telescopic end is fixedly connected to the lifting frame 51 to drive the lifting frame 51 to move up and down in the fixed frame 11.

[0052] Furthermore, a tilting frame 41 is mounted below the bag supply conveyor 4. The two ends of the tilting frame 41 are respectively hinged to the lifting frame 51, so that the bag supply conveyor 4 is hinged to the lifting frame. The lifting frame 51 is driven by the lifting drive device to drive the bag supply conveyor 4 to rise and fall. The tilting drive device 42 is hinged on the lifting frame 51. In this embodiment, the tilting drive device is preferably a hydraulic cylinder. Its telescopic end is hinged to the other side wall of the tilting frame 41, so that the tilting drive device 42 drives the bag supply conveyor 4 to tilt around the lifting frame 51. In this way, the tilting angle of the bag supply conveyor 4 can be adjusted to meet the dynamic spatial adaptation of the sorting platform and the conveying equipment in terms of height.

[0053] More preferably, in this embodiment, the packing conveyor belt 4 is not limited to one, but can also be provided with multiple packing conveyor belts 4 connected end to end. The turning frames 41 between adjacent packing conveyor belts 4 are hinged, wherein a first sickle connecting rod is hinged on one turning frame 41, and a second sickle connecting rod is hinged on another turning frame 41. The first sickle connecting rod is hinged to the other sickle connecting rod, and a second turning drive device is also hinged on the turning frame 41 hinged to the lifting frame 52. Its telescopic end is hinged to the connection between the first sickle connecting rod and the second sickle connecting rod, so that the second turning drive device drives the packing conveyor belts 4 to fold or unfold.

[0054] Reference Figure 1 , Figure 5 As shown, the present invention also includes a transfer robot 7. In this embodiment, the transfer robot 7 is a conveyor belt, and a transfer frame 73 is mounted below the transfer robot 7. Rollers 72 are rotatably arranged on both sides of the transfer robot 7 along the length direction. A transmission shaft is arranged between two rollers 72. A walking drive device is fixedly installed in the transfer frame 73. In this embodiment, the walking drive device is preferably a servo motor, and its output shaft is connected to the transmission shaft through a synchronous belt. The bottom surface of the transfer robot 7 is higher than the bottom surface of the rollers 72, so that the transfer robot 7 can travel on the ground under the drive of the walking drive device.

[0055] Combination Figures 6-8As shown, in this embodiment, a cavity 121 is provided inside the base frame 12, and the inner wall of the cavity is provided with a sliding groove 122 that slides with the roller 72. The transfer robot 7 is controlled by the control system to drive into the cavity 121 of the base frame 12, so that the roller 72 of the transfer robot 7 slides along the sliding groove 122, thereby storing the transfer robot 7 in the base frame 12 of the sorting platform 1. This not only saves transportation space, but also eliminates the need for special vehicles for transportation, bringing economic benefits by reducing operating costs for customers. When sorting work is required, it is only necessary to control the transfer robot 7 to drive out of the cavity and drive to the designated position to work.

[0056] In this embodiment, a lifting mechanism is provided below the head and tail ends of the transfer robot 7. The lifting mechanism includes a lifting plate, a first link, and a second link. In this embodiment, the first link and the second link are a pair. The upper parts of the first link and the second link are respectively hinged to the two sides of the transfer frame, and the middle parts of the first link and the second link are hinged together. The lower parts of the first link and the second link are respectively hinged to the lifting plate. A lifting drive device is hinged on the transfer frame. In this embodiment, the lifting drive device is preferably an electric push rod, whose telescopic end is hinged to the first link. A connecting rod is provided between the first links, so that the lifting plate is lowered in conjunction with the lifting drive device to lift the transfer robot 7.

[0057] The transfer frame 73 of the transfer robot 7 has several legs 71 rotatably arranged on both sides along its length. The upper part of the legs 71 is fixedly equipped with a transmission component, and the transmission components are connected by a chain. In this embodiment, the transmission component is preferably a sprocket. A rotary drive device is fixedly installed on the transfer frame 73. In this embodiment, a stepper motor is preferably used. The rotary drive device drives the chain to swing the legs 71 up and down. While the lifting mechanism drives the transfer robot 7 to rise, the rotary drive device drives the legs 71 to flip down and contact the ground. Then the lifting mechanism resets, so that the transfer robot 7 is supported by the legs 71.

[0058] Furthermore, in this embodiment, the support leg 71 is preferably an electric push rod, which can adjust the height of the transfer robot 7 according to the height difference between the package supply conveyor 4 and the logistics vehicle, so that the transfer robot 7 can be connected to the package supply conveyor 4 and the package can be sent onto the package supply conveyor by the transfer robot 7.

[0059] When no work is required, the lifting drive device drives the lifting plate to descend and support the transfer robot 7, the rotation drive device drives several legs to swing upward synchronously, and the lifting mechanism gradually drives the transfer robot 7 to descend until the roller 72 contacts the ground. The control system controls the transfer robot 7 to drive into the cavity.

[0060] In this embodiment, a positioning detection module is provided at the beginning of the packing conveyor belt. The positioning detection module preferably adopts a photoelectric sensor. When the positioning detection module detects that the end of the transfer robot has reached the beginning of the packing conveyor belt, the control system controls the transfer robot to stop moving, thereby realizing the automatic positioning of the transfer robot.

[0061] In addition, an energy storage module is provided on the transplanting frame. Several legs 71, a rotation drive device, and a walking drive device are electrically connected to the energy storage module. In this embodiment, the energy storage module is preferably a battery, which can store electricity through an external power source, so as to provide power to the transfer robot when there is no external power source.

[0062] The above setup allows the conveying equipment to be matched with the sorting equipment, enabling larger conveying equipment to be stored efficiently. The conveying equipment can be completely stored at the bottom of the sorting platform, saving transportation space and eliminating the need for dedicated vehicles. This not only reduces operating costs for customers and brings economic benefits, but also has significant implications for the application and promotion of mobile sorting in the industry.

[0063] Reference Figure 1 , Figure 9 As shown, the narrow strip sorting machine 2 includes a body 21 and several sorting trolleys 22. The inner wall of the body 21 is provided with a rotary guide rail 23, and the two ends of the several sorting trolleys are respectively slidably engaged with the rotary guide rail 23.

[0064] Combination Figure 10 , Figure 11 As shown, the sorting trolley 22 includes a sorting conveyor belt 221 and a sorting carrier 222. In this embodiment, the sorting conveyor belt 221 is composed of an electric roller 2211, a follower roller 2212, and a belt 2213. Side plates 2214 are provided on both sides of the sorting conveyor belt 221. The electric roller 2211 and the follower roller 2213 are respectively located between the ends of the side plates 2214. The belt 2213 is tensioned between the electric roller 2211 and the follower roller 2212 so that the electric roller 2211 drives the belt 2213 to rotate. This will not be elaborated here. The side plates on the sorting conveyor belt 221 are fixedly connected to the sorting carrier 222 by locking components. In this embodiment, the locking components are preferably screws and nuts, so that the faulty sorting conveyor belt can be easily removed from the sorting carrier 222 for replacement without stopping the machine for maintenance, which greatly improves work efficiency.

[0065] The rotary guide rail 23 includes an upward guide rail 231, a downward guide rail 232, and a turning guide rail 233. The upward guide rail 231 and the downward guide rail 232 are arranged parallel to each other vertically. The turning guide rails 233 are a pair and are respectively arranged between the upward guide rail 231 and the downward guide rail 232, so that several sorting trolleys 22 can rotate on the upward guide rail 231 and the downward guide rail 232 via the turning guide rail 233.

[0066] Furthermore, guide wheel assemblies 223 are provided at both ends of the sorting carrier 222, which slide in cooperation with the rotary guide rail 23. The guide wheel assembly 223 includes a first traveling wheel 2231 and a second traveling wheel 2232. The first traveling wheel 2231 and the second traveling wheel 2232 are arranged vertically and rotatably on the side wall of the sorting carrier 222. The first traveling wheel 2231 and the second traveling wheel 2232 slide in cooperation with the upward guide rail 231, the downward guide rail 232 and the turning guide rail 233, so that the irregular parts are more stable on the sorting trolley 22 and the conveying noise is reduced. In addition, the side wall of the sorting carrier 222 is provided with a transverse guide wheel 2233 that slides in cooperation with the machine body 21. The transverse guide wheel 2233 ensures that the sorting trolley 22 remains parallel to the side wall of the machine body during the movement, so that the sorting trolley 22 moves more smoothly.

[0067] Even better, the upward guide rail 231 and downward guide rail 232 are preferably made of solid square steel in one piece. Compared with traditional guide rails, they are not affected by sheet metal bending processes and plate welding deformation, which would affect the flatness and straightness of the track and ensure the stability of high-speed operation. In addition, the upward guide rail 231 and downward guide rail 232 are composed of several sections, and the ends of the upward guide rail 231 and downward guide rail 232 are provided with bevels so that the adjacent ends of the upward guide rail 231 and downward guide rail 232 can be connected by bevels. By adopting a stepless splicing method, it is not easy to produce obvious height differences during installation. Even if there is an obvious height difference between the upward guide rail 231 and downward guide rail 232, it will not have a significant impact on the sorting trolley 22 when it passes through, thus ensuring the smoothness of the guide rail.

[0068] Combination Figure 4 As shown, the turning guide rail 233 further includes several arc-shaped guide plates 2331. The arc-shaped guide plates 2331 are formed by laser cutting the shape of the turning guide rail using steel plates. Several arc-shaped guide plates 2331 are then stacked and fixed by welding. The stacked arc-shaped guide plates 2331 are then fixed to the machine body 21 by bolts. The ends of the arc-shaped guide plates 2331 are connected to the upward guide rail 231 and the downward guide rail 232, respectively.

[0069] The above-mentioned process can reduce manufacturing difficulty. At the same time, the trajectory of the turning guide rail 233 can smoothly transfer from the upward guide rail 231 and the downward guide rail 232 to the turning guide rail 233. Since the first traveling wheel 231 and the second traveling wheel 232 on the sorting cart 22 wrap around the turning guide rail 233, the extremely small gap between the first traveling wheel 2231 and the second traveling wheel 2232 and the turning guide rail 233 reduces the secondary impact of the first traveling wheel 2231 and the second traveling wheel 2232 on the turning guide rail 233 when the sorting cart 22 turns the turning guide rail 233, thus extending the life of the turning guide rail. This structure also allows the sorting cart to achieve high-speed sorting more safely and stably.

[0070] The sorting carriers 222 of several sorting carts 22 are hinged together by connecting parts 2221. In this embodiment, a linear motor stator 24 is fixedly installed on the body 1, and a linear motor mover 25 is fixedly installed at the bottom of the sorting cart 2. When the linear motor stator 24 is energized, it generates a magnetic field, causing the sorting cart 2 to move linearly along the upward guide rail 231 or the downward guide rail 232 under the interaction of the magnetic field, thereby conveying the package through several sorting carts 22.

[0071] The vehicle body 22 is equipped with wiring terminals. The wiring terminals of each sorting cart 22 are connected in series by wires, and the electric rollers on the sorting cart 22 are electrically connected to the wiring terminals. The first sorting cart 22 is equipped with a power module, which is electrically connected to the wiring terminals. The bottom of the sorting cart 22 is equipped with a sliding contact line moving end, which is electrically connected to the power module. The machine body is equipped with a sliding contact line fixed end 26 along the conveying direction. When the sorting cart 22 passes the sliding contact line fixed end, the sliding contact line moving end on the sorting cart 22 slides into contact with the sliding contact line fixed end, so that the sliding contact line fixed end continuously supplies power to the sorting cart 22, ensuring that the sorting cart 22 can move normally.

[0072] Reference Figure 2 , Figure 12 As shown, in this embodiment, fixed guide plates 31 are respectively provided on both sides of the narrow strip sorting machine 2, and a folding guide plate 32 is provided at the end of the fixed guide plate 31. The first end of the folding guide plate 32 is hinged to the sorting platform 1, and a folding drive device 321 is hinged on the sorting platform 1. In this embodiment, the folding drive device 321 is preferably a hydraulic cylinder, and its telescopic end is hinged to the folding guide plate 32, so that the folding guide plate 32 is folded or unfolded by the folding drive device 321.

[0073] Combination Figure 12 , Figure 13 As shown, further, the surfaces of the fixed guide plate 31 and the folding guide plate 32 are provided with a plurality of positioning holes 34 at intervals along the width direction. The fixed guide plate 31 and the folding guide plate 32 are respectively provided with a plurality of baffles 33. The bottom of the baffles 33 has a plurality of positioning pins 35 that match the positioning holes 34, so that a sorting chute 3 is formed between the baffles 33. By inserting the positioning pins into the positioning holes, quick insertion and removal can be achieved, thereby allowing the width of the sorting chute 3 to be adjusted according to different package sizes, which greatly improves the compatibility of the sorting chute.

[0074] Preferably, the baffle 33 has a wedge-shaped structure, making the sorting chute 3 wider at the top and narrower at the bottom, so that the goods can gradually move towards the middle. The top of the baffle 33 is also equipped with a handle to facilitate the staff to pick up the goods.

[0075] Reference Figures 1-12As shown, specifically, the working state of the sorting platform in this invention is as follows:

[0076] The sorting platform 1 is transported to the designated work location. The side wing drive device 131 and the rear wing drive device 141 respectively drive the side wing plates 13 and 14 outwards to unfold. Then, the folding drive device 321 drives the folding guide plate 32 outwards to unfold. Next, workers insert several baffles 33 onto the fixed guide plate 31 and the folding guide plate 32 according to the package specifications. Then, the lifting drive device 52 drives the lifting frame 51 to raise the package feeding conveyor belt 4, while the flipping drive device 42 drives the package feeding conveyor belt 5 to flip outwards until the end of the package feeding conveyor belt 4 is flush with the beginning of the narrow belt sorting machine 2. Finally, the cover is opened, and the control system controls the transfer robot 7 in the cavity to drive out and move between the supply belt conveyor and the logistics vehicle. The lifting mechanism lifts the transfer robot, and the rotary drive device drives several legs to flip downwards and contact the ground, so that the end of the transfer robot 7 connects with the supply belt conveyor 4. Thus, the transfer robot 7 and the supply belt conveyor 4 send the package into the narrow belt sorting machine 2. The narrow belt sorting machine 2 transports the package to the entrance of the corresponding sorting chute 3, so that the sorting conveyor belt on the sorting cart 22 sends the package into the sorting chute 3. The package slides into the corresponding sorting line through the sorting chute 3.

[0077] Reference Figures 1-12 As shown, the sorting platform is in a non-working state as follows:

[0078] The transfer robot 7 has several legs 71 on both sides retracted, and the transfer robot 7 is driven into the cavity by the control module. After the staff removes the baffles 33 on the fixed guide plate 31 and the folding guide plate 32, the folding drive device 321 drives the folding guide plate 32 to fold inward. The flipping drive device 42 also drives the bag supply belt 4 to flip upward until it is parallel to the fixed frame 11. At the same time, the lifting drive device 52 drives the lifting seat 51 to drive the bag supply belt 4 to descend. Finally, the side wing drive device 131 and the rear wing drive device 141 drive the side wing plate 13 and the rear wing plate 14 to close respectively, so that all the equipment is stored in the sorting platform 1.

[0079] Reference Figure 14 , Figure 15As shown, the inlet conveying module 6 includes a drive roller 61, a driven roller 62, a belt 63, and a conveyor frame 64. The driven rollers 62 are a pair and are rotatably mounted at both ends of the conveyor frame 64. The drive roller 61 is rotatably mounted within the conveyor frame 64. The belt 63 is tensioned on the drive roller 61 and the driven roller 62. In this embodiment, the driven roller 62 at the end of the conveyor frame 64 is located above the beginning of the machine body 21 to avoid gaps between the inlet conveying module 6 and the machine body, preventing packages from getting stuck in these gaps. Preferably, the driven roller 62 is a thin roller. This reduces the height difference between the belt 63 and the sorting cart 2, making the packages fed onto the sorting cart more smoothly. A support plate 65 is fixedly installed on the top surface of the conveyor frame 64 to support the surface of the belt 63, making the belt conveying more stable. A drive device is fixedly installed in the conveyor frame 64. In this embodiment, the drive device is preferably a servo motor, whose output shaft is connected to the drive roller 61 through a synchronous belt drive. Thus, the drive device drives the drive roller 61 to drive the belt 63 to rotate, feeding the packages one by one onto the sorting cart 22.

[0080] The conveyor frame 64 is equipped with a tensioning assembly 66 for adjusting the belt tension. The tensioning assembly 66 includes a tensioning roller. The side wall of the conveyor frame 64 is provided with a strip groove. The end of the tensioning roller is slidably engaged with the strip groove. The outer circumference of the tensioning roller abuts against the surface of the belt. An adjusting rod is threadedly connected to the side wall of the conveyor frame 64. The end of the adjusting rod is rotatably connected to the end of the tensioning roller. By rotating the adjusting rod, the horizontal movement of the tensioning roller can be adjusted, thereby adjusting the belt tension and ensuring the stability of the belt conveyor.

[0081] The end of the conveyor 64 is fixedly provided with a transition ramp 67 that connects to the belt 63, so that the packages on the belt 63 can be smoothly transferred to the sorting trolley 22, and the height difference between the belt and the sorting trolley 22 can be avoided so that the packages can deviate or roll.

[0082] More preferably, a photoelectric monitoring module is provided above the import conveyor module 6. In this embodiment, the photoelectric monitoring module preferably adopts a photoelectric sensor. During the process of the belt sending the package into the sorting cart 22, the length of the package is obtained by the trigger duration of the photoelectric monitoring module. A scanning module is also provided above the import conveyor module 6. In this embodiment, the scanning module includes a scanner and a grayscale meter. The barcode on the package is scanned by the scanner to obtain the barcode information of the package, and the position coordinate information of the package is obtained by the grayscale meter. In this embodiment, the photoelectric monitoring module and the scanning module are electrically connected to the control system so that the photoelectric monitoring module and the scanning module feed back the package information to the control system, so that the control system allocates the package to the corresponding sorting chute position according to the WSC system, and calculates the number and number of packages occupying the sorting cart according to the length of the package.

[0083] Reference Figures 1-16As shown, the present invention also provides a control method for a multifunctional mobile sorting device, comprising the following steps:

[0084] S101: The photoelectric monitoring module obtains the size of the package based on the trigger duration, and the scanning module obtains the bar information and location coordinate information of the package, and feeds it back to the control system;

[0085] S102: The control system allocates the position of the sorting chute according to the WSC system and calculates the number and number of sorting carts occupied by the packages;

[0086] S103: The control system uses a sorting cart to send the package to the corresponding sorting chute based on the location coordinates of the package fed back by the scanning module.

[0087] S104: The control system controls the sorting trolley to perform corresponding actions according to the different types of packages, and sends the packages onto the sorting chute.

[0088] In S104, when the package on the sorting trolley 22 is a regular item, the regular item is sent to the entrance end of the corresponding sorting chute 3 by the sorting trolley 22, so that the sorting conveyor belt 221 of the corresponding sorting trolley rotates one by one and sends the package into the sorting chute 3.

[0089] Combination Figure 14 , Figure 16 As shown, when the package on the sorting trolley 22 is a large item, the large item is sent to the entrance of the corresponding sorting chute 3 by the sorting trolley 22. The sorting conveyor belt 22 of the corresponding sorting trolley adopts a group operation. For example, if the large package occupies 6 sorting trolleys 22, after the first sorting trolley 22 reaches the entrance of the sorting chute, the sorting conveyor belt 221 of the first 3 sorting trolleys 22 rotates synchronously, so that the beginning of the large package gradually tilts towards the entrance of the sorting chute 3. Then the sorting conveyor belt 221 of the last 3 sorting trolleys 22 rotates synchronously, which avoids the situation of slippage due to overloading of a single sorting trolley 22, and ensures that the large package can slide down from the center of the sorting chute 3, and ensures that the large package can be sent into the sorting chute 3 in the center.

[0090] When the package on the sorting trolley 22 is a small item, after the sorting trolley 22 sends the package to the corresponding sorting chute 3, the sorting conveyor belt 221 of the sorting trolley 22 rotates synchronously, so that the small item can be fed into the sorting chute more smoothly, and the small item can be unloaded quickly.

[0091] By employing the aforementioned control methods, the narrow-band sorting machine becomes compatible with sorting various types of packages, which not only greatly improves sorting efficiency but also enhances sorting accuracy and reduces missorting and acceptance rates.

[0092] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They cannot be used to limit the scope of protection of the present invention. All modifications made according to the spirit of the main technical solution of the present invention should be covered within the scope of protection of the present invention.
