Description

Technical Field

[0001] This utility model relates to the field of logistics sorting technology, and in particular to an inclined feeding mechanism and a three-layer ring sorting device using the mechanism. Background Technology

[0002] As the logistics industry continues to demand higher sorting efficiency, multi-layer circular sorting equipment is gradually replacing traditional single-layer sorting equipment as the mainstream choice due to its advantages of high space utilization and strong parallel processing capabilities. In existing technologies, three-layer circular sorting equipment, through the coordinated operation of independent tracks and sorting carts in the upper, middle, and lower sorting layers, significantly increases the cargo throughput per unit time and effectively alleviates sorting pressure during peak logistics periods. However, in the core loading stage, the currently prevalent vertical loading method still has significant drawbacks, directly restricting the overall efficiency of the sorting system.

[0003] Specifically, the existing vertical loading operation process is as follows: Goods are first transported from the ground or storage area to the corresponding height position of each sorting layer via a vertical conveyor (such as an elevator, vertical conveyor belt, etc.). Then, the goods need to be transferred to the circular sorting trolley at that height. Since the sorting trolley in the circular sorting system always moves continuously along the circular track, while the output position of the goods of the vertical conveyor is fixed, in order to ensure that the goods can fall accurately and stably into the carrying cavity of the sorting trolley and avoid problems such as goods deviating, falling, or colliding with the trolley structure, the operating state of the sorting layer must be adjusted by the control system. That is, when the empty sorting trolley moves to the corresponding position of the loading station, the drive mechanism needs to reduce the running speed of the sorting trolley until the trolley stops completely. Only after the vertical conveyor smoothly transports the goods to the carrying area of ​​the trolley and completes the handover can the sorting trolley restart and return to the normal operating speed. This intermittent loading process of "cart stops - goods are handed over - cart restarts" directly disrupts the original continuous operation rhythm of the circular sorting system, forcing the sorting cycle to be extended.

[0004] More importantly, during peak logistics sorting periods, the volume of goods increases significantly, requiring the vertical conveyor to continuously transport goods to each sorting level. This leads to a significant increase in the frequency of stops for the sorting trolleys on the circular track. Frequent starts and stops not only exacerbate wear and tear on components such as the drive mechanism and track wheels, shortening equipment lifespan and increasing maintenance costs, but also cause empty sorting trolleys to form queues behind the loading station, resulting in localized congestion on the sorting track. Furthermore, since the loading actions at each sorting level are independent, excessively long loading handover times at one level can cause asynchronous sorting rhythms across multiple levels, further reducing the overall efficiency of the sorting system. In addition, to accommodate the loading needs of sorting levels at different heights, the vertical conveyor often requires separate design of conveyor paths and handover mechanisms for each level. This not only increases the structural complexity of the equipment but also raises the difficulty of installation and commissioning. Moreover, during the handover process, the inertial force generated by the trolley's pauses can cause the loaded goods to shift position, increasing the risk of subsequent sorting errors. In summary, the problem of "sorting trolleys needing to stop and wait for goods to be handed over" in the existing vertical feeding method has become the core bottleneck preventing the three-layer ring sorting equipment from fully realizing its high-efficiency sorting potential, and new technical solutions are urgently needed to solve it.

[0005] In view of this, a tilting feeding mechanism and a three-layer ring sorting device using the mechanism are proposed. Utility Model Content

[0006] The purpose of this invention is to provide an inclined feeding mechanism and a three-layer ring sorting device using the mechanism, which can effectively improve the sorting efficiency of the sorting device.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An inclined feeding mechanism, comprising: The frame has a loading surface and a lifting drive mechanism; A loading platform is slidably mounted on the frame and connected to the lifting drive mechanism. The loading platform is equipped with a conveying component, and the angle between the conveying direction of the conveying component and the loading surface is not a right angle.

[0008] In a preferred embodiment, the lifting drive mechanism includes a lifting drive motor, a drive gear, and a drive rack. The drive rack is vertically mounted on the frame, and the drive gear and the drive rack cooperate with each other. The lifting drive motor is mounted on the loading platform and connected to the drive gear.

[0009] In a preferred embodiment, at least two lifting drive mechanisms are provided, and they are evenly distributed on both sides of the feeding surface.

[0010] In a preferred embodiment, the frame is provided with a sliding groove, and the loading platform is provided with a slider, the slider cooperating with the slider.

[0011] In a preferred embodiment, the conveying assembly includes a receiving conveyor and a plurality of feeding conveyors. The plurality of feeding conveyors have different lengths and are arranged in parallel. One end of each feeding conveyor is flush with the end of the receiving conveyor, and the other end is arranged according to the position of the feeding surface.

[0012] In a preferred embodiment, the conveying assembly is provided in two or more parts.

[0013] In a preferred embodiment, a fixed conveyor is further included, which is fixedly mounted on the frame and used to transport goods to the receiving conveyor.

[0014] A three-layer ring sorting mechanism, including the aforementioned inclined feeding mechanism.

[0015] Compared with existing technologies, the frame of this invention serves as a basic support component. Its loading surface is parallel and close to the side of the three-layer circular sorting equipment, providing a spatial reference for the sliding of the loading platform and the transportation of goods. This ensures that the loading path and the running trajectory of the sorting trolley are always within the appropriate range. The lifting drive mechanism can drive the loading platform to slide along the frame, thereby adjusting the height of the loading platform and the conveying components to match the height requirements of the upper, middle, and lower sorting layers in the three-layer circular sorting equipment, achieving targeted loading for the sorting trolleys of each sorting layer. The core lies in the fact that the conveying direction of the conveying components is not perpendicular to the loading surface. This inclined conveying direction allows the conveying components to impart a resultant velocity to the goods in two directions when driving the goods to move—including both the component velocity along the vertical direction (corresponding to the height direction of the sorting layer) and the component velocity along the running direction of the sorting trolley. When the sorting trolley runs continuously along the circular track, the output speed of the conveying component along the direction of the trolley's movement can be dynamically matched with the speed of the sorting trolley. At the same time, the vertical speed ensures that the goods can be smoothly transferred from the conveying component to the carrying area of ​​the sorting trolley without having to reduce the speed of the sorting trolley or stop it to wait for the goods to be handed over, thus breaking the limitation of "stopping and handing over" in traditional vertical feeding.

[0016] This mechanism significantly improves the overall operational efficiency of the sorting system. Dynamic speed matching achieved through inclined conveying allows the sorting trolleys to maintain continuous cyclical operation, avoiding prolonged sorting cycles caused by frequent starts and stops. It also eliminates queuing and congestion problems caused by trolley stops. Especially during peak logistics periods, it fully unleashes the parallel processing capacity of the three-layer circular sorting equipment, greatly increasing the throughput per unit time. Secondly, it reduces equipment wear and maintenance costs. The sorting trolleys do not require frequent starts and stops, reducing wear on moving parts such as the drive mechanism and track wheels, extending equipment lifespan. Simultaneously, the seamless connection between the conveyor components and the sorting trolleys avoids cargo shifting due to start-stop inertia, reducing the sorting error rate. Furthermore, the mechanism boasts excellent adaptability and flexibility. The lifting drive mechanism, which drives the loading platform, allows for quick switching to any sorting layer of the three-layer circular sorting equipment, eliminating the need for separate loading mechanisms for each layer. This simplifies the overall equipment structure and reduces installation and commissioning difficulties. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law. Example

[0023] An inclined feeding mechanism, comprising: Frame 1, which has a loading surface 2 and a lifting drive mechanism; A loading platform is slidably mounted on the frame 1 and connected to the lifting drive mechanism. The loading platform is equipped with a conveying component, and the angle between the conveying direction of the conveying component and the loading surface 2 is not a right angle.

[0024] In this embodiment, the frame 1 of the inclined feeding mechanism serves as the basic support component. Its feeding surface 2 is parallel and close to the side of the three-layer circular sorting equipment, providing a spatial reference for the sliding of the feeding platform and the transport of goods. This ensures that the feeding path and the running trajectory of the sorting trolley are always within the appropriate range. The lifting drive mechanism can drive the feeding platform to slide along the frame 1, thereby adjusting the height of the feeding platform and the conveying components to match the height requirements of the upper, middle, and lower sorting layers in the three-layer circular sorting equipment, achieving targeted feeding of the sorting trolleys at each sorting layer. The core advantage lies in the fact that the conveying direction of the conveying components is not perpendicular to the feeding surface 2. This inclined conveying direction allows the conveying components to impart a resultant velocity to the goods in two directions when driving their movement—including a component velocity along the vertical direction (corresponding to the sorting layer height direction) and a component velocity along the running direction of the sorting trolley. When the sorting trolley runs continuously along the circular track, the output speed of the conveying component along the direction of the trolley's movement can be dynamically matched with the speed of the sorting trolley. At the same time, the vertical speed ensures that the goods can be smoothly transferred from the conveying component to the carrying area of ​​the sorting trolley without having to reduce the speed of the sorting trolley or stop it to wait for the goods to be handed over, thus breaking the limitation of "stopping and handing over" in traditional vertical feeding.

[0025] This mechanism significantly improves the overall operational efficiency of the sorting system. Dynamic speed matching achieved through inclined conveying allows the sorting trolleys to maintain continuous cyclical operation, avoiding prolonged sorting cycles caused by frequent starts and stops. It also eliminates queuing and congestion problems caused by trolley stops. Especially during peak logistics periods, it fully unleashes the parallel processing capacity of the three-layer circular sorting equipment, greatly increasing the throughput per unit time. Secondly, it reduces equipment wear and maintenance costs. The sorting trolleys do not require frequent starts and stops, reducing wear on moving parts such as the drive mechanism and track wheels, extending equipment lifespan. Simultaneously, the seamless connection between the conveyor components and the sorting trolleys avoids cargo shifting due to start-stop inertia, reducing the sorting error rate. Furthermore, the mechanism boasts excellent adaptability and flexibility. The lifting drive mechanism, which drives the loading platform, allows for quick switching to any sorting layer of the three-layer circular sorting equipment, eliminating the need for separate loading mechanisms for each layer. This simplifies the overall equipment structure and reduces installation and commissioning difficulties.

[0026] Furthermore, the lifting drive mechanism includes a lifting drive motor 3, a drive gear, and a drive rack 4. The drive rack 4 is vertically mounted on the frame 1. The drive gear and the drive rack 4 mesh together. The lifting drive motor 3 is mounted on the loading platform and connected to the drive gear. The lifting drive motor 3 is mounted on the loading platform and drives the drive gear to rotate. Because the drive rack 4 is vertically fixed on the frame 1 and meshes with the drive gear, the rotational motion of the drive gear is converted into linear motion along the drive rack 4 through tooth surface meshing, thereby driving the loading platform to slide stably along the frame 1, realizing the height adjustment of the loading platform and conveying components. The gear and rack meshing transmission has high precision, which can accurately control the lifting height of the loading platform and ensure precise alignment with each sorting layer of the three-layer ring sorting equipment; the transmission process is stable and the driving torque is sufficient, which can adapt to the loading needs of goods of different weights; the structure is compact and has a low failure rate, eliminating the need for complex transmission components, reducing maintenance costs, and at the same time, it can quickly respond to height adjustment needs, improving the switching efficiency of loading each sorting layer.

[0027] Furthermore, at least two lifting drive mechanisms are provided, evenly distributed on both sides of the loading surface 2. During operation, the lifting drive motors 3 on both sides can synchronously drive their respective drive gears to rotate. Through the meshing transmission of the gears and vertical racks, they jointly drive the loading platform to slide along the frame 1. Since the driving forces on both sides are symmetrically distributed and act synchronously, it can effectively avoid tilting, jamming, or deviation of the loading platform during lifting due to uneven force on one side, ensuring that the loading platform always maintains a stable horizontal posture, thereby ensuring the precise docking of the conveying components with the sorting carts of each sorting layer. At the same time, the dual-side drive structure can distribute the load pressure of a single drive mechanism, reduce the wear of a single motor and transmission components, and extend the service life of the equipment. Even if one drive mechanism experiences a temporary failure, the other mechanism can still maintain the basic lifting function of the loading platform or maintain the current height, reducing the overall loading interruption caused by a single point of failure, improving the reliability and fault tolerance of the mechanism operation, and better adapting to the continuous and efficient loading requirements of the three-layer ring sorting equipment.

[0028] Furthermore, the frame 1 is provided with a sliding groove, and the loading platform is provided with a slider, which cooperates with the slider. When the loading platform adjusts its height along the frame 1 under the drive of the lifting mechanism, the slider will always be engaged in the sliding groove and slide along the extension direction of the groove. Through the limiting and guiding effect of the sliding groove on the slider, the movement trajectory of the loading platform is constrained, ensuring that it moves smoothly only in the vertical direction and avoiding lateral deviation or swaying.

[0029] Furthermore, the conveying assembly includes a receiving conveyor 5 and multiple feeding conveyors 6. The multiple feeding conveyors 6 have different lengths and are arranged in parallel. One end of each feeding conveyor 6 is flush with the end of the receiving conveyor 5, and the other end is arranged according to the position of the feeding surface 2. The receiving conveyor 5 first receives external materials and stably conveys the goods to its end, after which the goods are transferred to the multiple feeding conveyors 6 arranged in parallel. Because the multiple feeding conveyors 6 have different lengths and are flush with the end of the receiving conveyor 5 at one end and arranged at the position of the feeding surface 2 at the other end, this length difference, combined with the inclined reference of the feeding surface 2, makes the feeding conveyors 6 form an inclined conveying plane that is adapted to the running trajectory of the sorting trolley. At the same time, by controlling the running speed of each feeding conveyor 6, the speed difference between adjacent feeding conveyors 6 is used to apply a guiding force to the goods, gradually adjusting the movement posture and direction of the goods, ensuring that the goods can obtain a component speed along the running direction of the sorting trolley to match the rhythm of the trolley's movement, and also obtain a vertical component speed through the inclined arrangement to adapt to the height of the sorting layer, ultimately achieving a precise transition of goods to the sorting trolley.

[0030] From a technical perspective, the segmented design of the connecting conveyor 5 and the feeding conveyor 6 separates the functions of incoming material buffering and precise conveying, preventing external material fluctuations from directly affecting the feeding accuracy and improving feeding stability. The speed difference adjustment method of multiple feeding conveyors 6 can more flexibly adapt to the turning requirements of goods of different sizes and weights compared to fixed-speed conveying, reducing the deviation or jamming of goods during inclined conveying and ensuring that the posture of the goods meets the carrying requirements of the sorting cart. The length-differentiated arrangement and the cooperation with the feeding surface 2 can construct an inclined conveying path without the need for additional complex turning mechanisms, simplifying the structural complexity of the conveying components and reducing equipment manufacturing costs and maintenance difficulties. In addition, this structure can continuously provide a smooth speed transition for goods, further ensuring uninterrupted docking with the sorting cart. With the height adjustment of the lifting drive mechanism, it can stably adapt to the feeding requirements of each layer of carts in the three-layer ring sorting equipment.

[0031] Furthermore, the conveying assembly is provided in two or more parts to improve feeding efficiency.

[0032] Furthermore, it also includes a fixed conveyor 7, which is fixedly mounted on the frame 1 and is used to transport goods to the receiving conveyor 5. After receiving the goods, the receiving conveyor 5 lifts and lowers the goods through a lifting drive mechanism to transport the goods to the sorting cart on the designated layer. Example
