Description

Technical Field

[0001] The present application relates to the technical field of express delivery sorting, and in particular to a linear sorting system and a sorting method. Background Art

[0002] In the conveying equipment of the logistics and warehousing industry, there are high requirements for accuracy and operating efficiency in the rapid sorting process. The existing narrow-band sorting machines are usually used to sort and divert non-standard parts, special-shaped parts or thin and light parts that appear in logistics transportation.

[0003] At present, narrow-band sorting machines generally use single-layer linear motors to drive the sorting carts, and the linear motors drive the upper and lower cart queues at the same time; however, each sorting cart needs to be additionally equipped with a power module to deliver the express to the corresponding storage bin, which not only increases the purchase cost of the narrow-band sorting machine, but also increases the operating cost. Summary of the invention

[0004] The purpose of the present application is to provide a linear sorting system and a sorting method in order to solve the problem of multiple power modules of existing narrow-band sorting machines.

[0005] In the first aspect, the present application provides a linear sorting system, which adopts the following technical solution: A linear sorting system includes a plurality of storage bins, an ornament conveyor belt, a sorting component, a scanning component, and a sorting component. The output end of the ornament conveyor belt is connected to the sorting component. A plurality of storage bins are arranged on both sides of the sorting component. The storage bins are connected to the output end of the sorting component. The scanning component is set on the ornament conveyor belt.

[0006] By adopting the above technical solution, the storage bins are distributed on both sides of the sorting component, so that the sorting component can easily divert items to different storage bins. This layout is conducive to improving sorting efficiency and space utilization, and reducing cross-interference of items during transportation; the cycloid conveyor belt transports items from the outside to the sorting component. Its conveying direction matches the running direction of the sorting component to ensure that the items can enter the sorting component smoothly; the sorting component sorts and diverts the items. It uses a series of mechanical structures and power systems to accurately transfer items from the conveyor belt to the corresponding storage bin according to the characteristics of the items and the location of the target storage bin; the scanning component enables the sorting system to understand the status and characteristics of the items in real time, so as to sort according to preset rules and algorithms. For example, the target storage bin is determined based on the barcode information of the item.

[0007] Optionally, the sorting component includes a bracket, a plurality of sorting modules installed on the bracket, a transverse conveyor belt installed on the sorting module, a power shaft rotatably connected to the bracket, a linkage component connecting the power shaft and the transverse conveyor belt, a power source for installing the bracket, and a connecting component connecting the sorting module and the power source. The sorting modules are connected end to end in a closed loop in sequence, and the power source drives the sorting modules to move through the connecting component. The transport direction of the transverse conveyor belt is perpendicular to the moving direction of the sorting module.

[0008] By adopting the above technical solution, the transverse conveyor belt on each sorting module obtains power from the same power shaft through a linkage component, which greatly reduces the setting of power equipment such as motors and greatly reduces energy consumption. The power source causes the sorting module to circulate through the connecting component, so that the express can be transported to the corresponding storage warehouse, and the transverse conveyor belt transports the express to the corresponding storage warehouse. The transportation direction of the transverse conveyor belt can be switched, so that the express can be transported to different storage warehouses on both sides.

[0009] Optionally, the sorting module includes a shell and guide wheels installed on both sides of the shell, the bracket is provided with a circulating track, the guide wheels can move along the track of the circulating track, and the circulating track is arranged longitudinally.

[0010] By adopting the above technical solution, the shell serves as the main body of the sorting module, carrying and protecting various internal components. It provides a stable structural framework for the sorting module, ensuring that the components maintain relative positions and functions during operation; the guide wheels are installed on both sides of the shell, cooperating with the circulating track on the bracket. The circular motion of the sorting module and the longitudinal arrangement of the track enable the sorting system to operate efficiently in a limited space. Through reasonable layout and design, the sorting module can quickly and accurately complete the sorting and transfer of items, improving the sorting efficiency.

[0011] Optionally, the connecting assembly includes a connecting gear fixedly connected to the output end of the power source, the housing is provided with a tooth groove, the tooth groove is meshed with the connecting gear, and the output end of the power source is connected to the power shaft through a gear.

[0012] By adopting the above technical solution, the tooth grooves set on the shell are meshed with the connecting gears. When the connecting gears rotate under the drive of the power source, the shell will be driven to move synchronously through the principle of gear meshing. Since the gear meshing has a specific transmission ratio and precise motion transmission characteristics, the shell can move along the circular track at a predetermined speed and direction, realizing the orderly and precise displacement of the sorting module, and providing a stable position change basis for subsequent sorting operations; the output end of the power source is connected to the power shaft through gears to form a complete power transmission chain. The power of the power source is first transmitted to the connecting gear, and the connecting gear then transmits part of the power to the power shaft through the gear connection with the power shaft, so that the power shaft can also obtain the corresponding rotational power, thereby driving other components associated with it (such as transverse conveyor belts, etc.) to operate.

[0013] Optionally, the linkage assembly includes a rotating frame rotatably connected to both sides of the shell, a first force transmission shaft and a second force transmission shaft rotatably connected to the rotating frame, a shift plate rotatably connected to the shell, and a connecting rod rotatably connected to the rotating frame, the installation positions of the first force transmission shaft and the second force transmission shaft are symmetrical about the power axis, the other end of the connecting rod is at the shift plate, and a first spring is provided between the shell and the shift plate, and the first spring forces the shift plate to rotate in a direction away from the power axis.

[0014] By adopting the above technical solution, the rotating frame connected to the rotating frame on both sides of the shell provides a support and rotation basis for the first force transmission shaft and the second force transmission shaft. It enables the force transmission shaft to rotate flexibly within a certain range; the paddle is connected to the rotating frame through a connecting rod to form a linkage mechanism. When an external trigger signal acts on the paddle, the rotation of the paddle is transmitted to the rotating frame through the connecting rod, thereby driving the force transmission shaft to change its power transmission state; the first spring between the shell and the paddle plays a key reset and pre-tightening role. Under normal conditions, the first spring forces the paddle to rotate in a direction away from the power shaft, so that the linkage assembly is in an initial standby state. When the paddle is subjected to an external force, the spring is compressed and stores elastic potential energy; once the external force disappears, the spring releases energy and pulls the paddle back to the initial position to prepare for the next power transmission operation.

[0015] Optionally, a plurality of screw rod assemblies are arranged on the bracket, the output end of the screw rod assembly is fixedly connected to a moving platform, the moving platform is fixedly connected to a trigger rod, the trigger rod is provided with a bending portion, and the bending portion can be connected to the shift plate.

[0016] By adopting the above technical solution, during the sorting process, when it is necessary to start the transverse conveyor belt to sort items, the control system will drive the screw assembly to operate according to the preset program or information fed back by the sensor. The rotation of the screw causes the nut to drive the mobile platform to move in a predetermined direction, and the mobile platform drives the trigger rod and its bent portion to move synchronously. When the bent portion of the trigger rod moves to a position in contact with the paddle plate, the bent portion applies a force to the paddle plate, overcoming the elastic force of the first spring between the paddle plate and the shell, causing the paddle plate to rotate. The rotation of the paddle plate is transmitted to the rotating frame through the connecting rod, thereby driving the first force transmission shaft and the second force transmission shaft to change their power transmission state, transmitting power from the power shaft to the transverse conveyor belt, realizing the start of the transverse conveyor belt, and thus transporting the items to the designated location for sorting.

[0017] Optionally, a first cavity and a second cavity are provided on both sides of the shell, and the first cavity and the second cavity are rotatably connected with the first rotating shaft and the second rotating shaft, the first rotating shaft is fixedly connected to the rotation center of the rotating frame, the first rotating shaft sleeve is provided with a first pulley, the first force transmission shaft and the second force transmission shaft are fixedly connected with the second pulley, the first pulley and the second pulley are connected by a connecting belt, the end face of the first pulley is fixedly connected with the first gear, the second rotating shaft sleeve is provided with a second gear, the first gear is meshed with the second gear, the second rotating shaft is fixedly connected with an output member, and the output member is connected to the transverse conveyor belt.

[0018] By adopting the above technical solution, the first cavity and the second cavity set on both sides of the shell provide a storage space for the internal transmission components, making the transmission structure more compact and orderly. In each cavity, the first rotating shaft and the second rotating shaft are installed by means of rotational connection; since the first force transmission shaft and the second force transmission shaft both rotate around the rotation center of the rotating frame, the first rotating shaft is fixedly connected to the rotation center of the rotating frame, so that the connection belt between the first force transmission shaft and the second force transmission shaft will not be affected, ensuring the effective transmission of power from the force transmission shaft to the rotating shaft; the second gear is sleeved on the second rotating shaft, and the second gear and the second rotating shaft are initially in a clutch state, and the second gear cannot drive the second rotating shaft to rotate, so that when one of the force transmission shafts rotates, it will not drive the other force transmission shaft to rotate.

[0019] Optionally, the second rotating shaft sleeve sliding key is connected to a moving ring, a closed-loop annular groove is provided on the reversing side of the moving ring, the first rotating shaft sliding key is connected to a moving plate, the inner walls of the first cavity and the second cavity are provided with inclined platforms, the moving plate is rotatably connected to a ball, the ball can move along the inclined platform, a second spring is provided between the first gear and the moving plate, the second spring forces the moving plate to move toward the direction of the inclined platform.

[0020] By adopting the above technical solution, the second shaft sleeve sliding key is connected to the moving ring, so that the moving ring can slide axially on the second shaft and rotate with the second shaft; the first shaft sliding key is connected to the moving plate, so that the moving plate can rotate around the first shaft and slide relatively axially; the inclined platform on the inner wall of the first cavity and the second cavity cooperates with the ball on the moving plate. When the system is running, the ball will cause the moving plate to produce axial displacement under the action of the inclined platform, thereby driving the moving ring to rotate on the second shaft; the second spring between the first gear and the moving plate plays a key role in pre-tightening and resetting. The spring forces the moving plate to move toward the inclined platform, so that the ball always maintains close contact with the inclined platform.

[0021] Optionally, a circular groove is provided on one side of the second gear, and the second rotating shaft is fixedly connected to a rotating block, the rotating block is located in the circular groove, the rotating block is provided with a plurality of symmetrical sliding grooves, a slider is slidingly connected in the sliding groove, the slider can abut against the inner wall of the second gear, the slider is rotatably connected to an abutment rod, and the other end of the abutment rod is rotatably connected to the movable ring.

[0022] By adopting the above technical solution, when the moving ring moves, the slider is pushed to move along the slide groove by the abutment rod. The abutment rod decomposes the axial thrust of the moving ring and transmits it to the slider, so that the slider slides in the slide groove toward the inner wall of the second gear. As the slider moves, the slider gradually abuts against the inner wall of the second gear. In this process, the contact pressure between the slider and the inner wall of the second gear gradually increases until it reaches a level that can reliably transmit power; when the slider is tightly abutted against the inner wall of the second gear, the second gear rotates under the drive of the power source, and relying on the friction and interaction between the two, the rotational power of the second gear is transmitted to the rotating block through the slider, and then because the rotating block is fixedly connected to the second rotating shaft, the power is finally smoothly transmitted to the second rotating shaft, and then drives the output member connected to the second rotating shaft to drive the transverse conveyor belt to operate.

[0023] In the second aspect, the present application provides a sorting method, which adopts the following technical solution: A sorting method comprises the following steps: S1. Place the express on the conveyor belt through manual placement or / and equipment placement; S2, the courier obtains the corresponding logistics information and sorting information through the scanning component; S3. The display conveyor belt transports the express to the sorting component, and the sorting component facilitates the transportation of the express to the corresponding storage bins on both sides.

[0024] By adopting the above technical solution, the scanning component can quickly and accurately obtain logistics information, such as the source, destination, and delivery time of the express delivery, by scanning the barcode, QR code and other labels on the express package. This information is crucial for the tracking and management of the entire logistics connection belt. It is not only convenient for the express company to grasp the flow of express delivery, but also allows customers to understand the location and status of their packages in real time through the corresponding query platform; in addition to logistics information, the scanning component will also obtain sorting information according to the sorting rules set by the destination, region, and item type of the express delivery. For example, according to different cities, different distribution stations or different commodity categories, determine which storage warehouse the express delivery should eventually be sorted to, providing a key basis for the accurate operation of the subsequent sorting components.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By acquiring the logistics and sorting information of the express through the scanning component, it is possible to quickly and accurately determine the storage bin to which each express should be sorted, greatly improving the accuracy of sorting, reducing human errors, and improving the overall efficiency and accuracy of logistics distribution; the design of the sorting component enables the express to be quickly transported from the display conveyor belt to the corresponding storage bin, multiple sorting modules work together, and the transportation direction of the horizontal conveyor belt cooperates with the moving direction of the sorting module to achieve efficient diversion and transportation, which can cope with the sorting tasks of a large number of express deliveries and increase the sorting volume per unit time.

[0026] 2. In the linkage assembly, the trigger rod is driven by the screw assembly to control the contact between the paddle and the first force transmission shaft or the second force transmission shaft, so that the transverse conveyor belt can be reversed as needed, meeting the needs of sorting storage bins in different directions, enhancing the flexibility and adaptability of the system, and being able to better cope with complex sorting scenarios and storage bin layouts.

[0040] In the initial state, the rotating frame 554 of the linkage assembly 55 maintains balance under the action of the first springs 552 on both sides, so that the first force transmission shaft 561 and the second force transmission shaft 562 are both separated from the power shaft 56, and the transverse conveyor belt 532 is stationary. When the screw assembly 512 on the bracket 51 rotates forward, the moving platform 514 drives the trigger rod 513 to move to the moving path of the dial plate 551. After the dial plate 551 contacts the bending portion 5132, it rotates toward the power shaft 56 under the action of the connecting assembly 54, so that the first force transmission shaft 561 abuts against the power shaft 56, and the power shaft 56 drives the first force transmission shaft 561 to rotate, and through a series of transmission structures such as belt transmission, the transverse conveyor belt 532 is driven to run in one direction to deliver the express to the corresponding storage bin 3. When the screw assembly 512 rotates in the opposite direction, the shift plate 551 moves to make the second force transmission shaft 562 abut against the power shaft 56. Due to the special gear structure of the second cavity 59, the second force transmission shaft 562 drives the transverse conveyor belt 532 to rotate in the opposite direction, thereby realizing express sorting and transportation in different directions.

[0041] In the linkage assembly 55, the first force transmission shaft 561 and the second force transmission shaft 562 realize contact and separation control with the power shaft 56 through the rotating frame 554, the connecting rod 553 and the cooperation with the paddle 551 that are rotatably connected to the two sides of the housing 535. At the same time, the rotation of the first force transmission shaft 561 and the second force transmission shaft 562 drives the first rotating shaft 563 to rotate through the transmission components such as the pulley and the connecting belt, and the first gear 568 on the first rotating shaft 563 meshes with the second gear 565 on the second rotating shaft 564 to transmit power to the second rotating shaft 564, and the second rotating shaft 564 is connected to the transverse conveyor belt 532 through the output member, driving the transverse conveyor belt 532 to operate. When the system is running, the inclined platform 5632 on the inner wall of the first cavity 58 and the second cavity 59 cooperates with the ball 5633 on the moving plate 5631. Under the action of the ball 5633, the moving plate 5631 produces axial displacement, driving the moving ring 569 to rotate on the second rotating shaft 564. At the same time, the second spring 5655 between the first gear 568 and the moving plate 5631 ensures that the ball 5633 is in close contact with the inclined platform 5632. When the moving ring 569 moves, the contact rod 5653 pushes the slider 5654 to move along the slide groove 5652, so that the slider 5654 is pressed against the inner wall of the second gear 565, so that the power is transmitted from the second gear 565 to the second rotating shaft 564 through the slider 5654 and the rotating block 5651, and finally drives the transverse conveyor belt 532 to operate, completing the express sorting operation.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
