Description

Technical Field

[0001] This invention relates to the field of logistics grading and sorting technology, specifically to a logistics grading and sorting conveyor belt. Background Technology

[0002] As the core equipment for logistics transportation, the efficiency and reliability of the conveyor belt in the terminal sorting stage directly affect the throughput capacity of the entire logistics system.

[0003] Traditional logistics sorting conveyors typically use fixed baffles, swing levers, or multiple independent conveyor belts for diversion at the discharge end. Fixed baffles are simple in structure but offer only one sorting direction and lack flexibility. While swing levers can achieve multi-directional sorting, they usually require an independent drive mechanism (such as cylinders or motors) for each sorting direction, and coordination is achieved through complex linkage devices or control programs. Furthermore, levers cannot adaptively adjust to the actual properties (such as weight) of the materials being sorted. When dealing with ultra-light (easily floating), ultra-heavy, or fragile items, levers and push rods pose a risk of incomplete action or impact damage to the goods.

[0004] Therefore, this application proposes a logistics classification and sorting conveyor belt. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a logistics grading and sorting conveyor belt.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A logistics grading and sorting conveyor belt, comprising: The base has a conveyor belt mounted on its supporting surface; The receiving plate is located at the discharge end of the conveyor belt along its length. The coupling assembly has its two ends located on the underside of the conveyor belt and the receiving plate, respectively. The receiving plate swings around the discharge end of the conveyor belt via the coupling assembly. The guide plate is located on the lower side of the receiving plate along the length of the receiving plate. The top view of the guide plate is horizontally T-shaped. The protruding end in the middle is along the length of the receiving plate, and the protruding ends on both sides are symmetrically arranged along the width of the receiving plate. The bottom of each protruding end is sloping, and a guide groove is opened along the slope. A support groove is formed at the intersection of the three guide grooves. The sliding member, with its top end abutting against the support groove, includes: The slider is located in the support groove, with its lower end protruding from the support groove and equipped with a drive source, and its top periphery is inclined. The connecting block is located on the lower periphery of the slider along the direction of the protruding end of the guide plate; The end block is located at the end of the connecting block away from the slider and matches the guide groove on the same side.

[0007] When the electric slider slides to the left along the electric slide rail, the right end of the receiving plate swings downward around axis two, unloading the material into material frame one; when the electric slider slides forward or backward along the electric slide rail, the receiving plate rotates around axis one, unloading the material into material frame two and material frame three.

[0008] Preferably, the coupling assembly includes: Mounting plate one, which is fixed to the lower side of the conveyor belt discharge end; Mounting plate two is located on the underside of the receiving plate; Shaft 2 is rotatably mounted on the side wall of mounting plate 2 along the width direction of the receiving plate; Shaft 1, with its two ends rotatably mounted on mounting plate 1 and shaft 2 along the length of the receiving plate.

[0009] Preferably, the driving source includes: The electric slide rail is located on the base support surface and matches the sliding trajectory of the sliding component. The electric slider has its top end vertically positioned on the lower side of the slider, and its lower end slides along the electric slide rail.

[0010] Preferably, the cross-section of the guide groove is V-shaped, U-shaped, or dovetail-shaped.

[0011] Preferably, the trajectory of the electric slide rail matches the top view shape of the guide plate and includes three straight tracks corresponding to the three protruding ends of the guide plate, respectively.

[0012] Preferably, the drive source further includes a control unit for controlling the movement of the electric slider along the electric slide rail, the control unit being communicatively connected to the central controller of the sorting system.

[0013] Preferably, the angle between the top peripheral inclined surface of the slider and the horizontal plane is 30° to 60°.

[0014] Preferably, the slope of the bottom of each protruding end of the guide plate gradually increases in the direction away from the support groove.

[0015] Preferably, the system is also equipped with a scanner for identifying cargo information, and the scanner is communicatively connected to the central controller of the sorting system.

[0016] Preferably, the pressure sensor is disposed on the upper surface of the receiving plate and is used to detect the load weight on the receiving plate; the control module is connected to the pressure sensor and the drive source signal and is configured to: The system receives the weight signal from the pressure sensor and controls the speed at which the sliding member is driven by the drive source according to a preset weight-swing speed mapping relationship, so that the swing speed of the receiving plate is negatively correlated with the current load weight.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention creatively adopts a cooperation mechanism of "T"-shaped guide plate and integrated sliding component. Through a "T"-shaped guide plate and its converging guide groove, the power of a linear drive (electric slider) is cleverly transformed into the precise oscillation of the receiving plate in three different directions. This design replaces the multiple independent drive mechanisms commonly used in traditional multi-directional sorting with a single drive source (electric slide rail and slider) and a simple mechanical structure. This greatly simplifies the mechanical structure, reduces the number of parts, and lowers the equipment manufacturing cost and subsequent maintenance complexity.

[0018] 2. The guide groove of this invention physically constrains the movement path of the sliding component, and the trajectory of the electric slide rail precisely matches it. This dual guarantee ensures the uniqueness and accuracy of the sorting action and effectively prevents malfunctions. The coupling assembly adopts a directional joint type shaft connection, providing a stable and flexible two-degree-of-freedom swing foundation for the receiving plate, making the sorting action smooth and precise. The multiple optional schemes for the cross-sectional shape of the guide groove (V-shaped, U-shaped, dovetail-shaped) and the optimized range of the slider slope angle (30°-60°) give the receiving plate more flexibility and reliability. The gradual slope design at the bottom of the guide plate is a clever dynamic optimization, making the receiving plate stable at the start of the swing and tilting quickly and thoroughly at the end of the unloading, further improving the efficiency and reliability of the sorting action.

[0019] 3. By adding a pressure sensor and an intelligent control module, this invention enables the equipment to sense weight. The control module dynamically adjusts the sorting swing speed according to the preset logic of the negative correlation between weight and speed. It sorts heavy items slowly and smoothly, ensuring the safety of goods and equipment and reducing impact and noise. It sorts light items quickly, effectively shortening the operation cycle. This adaptive capability optimizes the overall sorting efficiency while ensuring operational safety, achieving the best balance between safety and efficiency. Attached Figure Description

[0022] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention. Example

[0023] like Figures 1-8 As shown, a logistics grading and sorting conveyor belt includes: a base on which a conveyor belt 1 is mounted; a receiving plate 5 disposed along the length of the conveyor belt 1 at the discharge end of the conveyor belt 1; a coupling assembly with its two ends disposed on the lower sides of the conveyor belt 1 and the receiving plate 5 respectively, the receiving plate 5 swinging around the discharge end of the conveyor belt 1 via the coupling assembly; and a guide plate 6 disposed along the length of the receiving plate 5 at the lower side, the guide plate 6 having a horizontal T-shape in its top view, the protruding end in the middle along the length of the receiving plate 5, the protruding ends on both sides being symmetrically arranged along the width of the receiving plate 5, the bottom of each protruding end being sloping, and a guide groove 61 being formed along the slope, the intersection of the three guide grooves 61 forming a support groove 9. The sliding member 8, with its top end abutting against the support groove 9, includes: a slider 83, disposed in the support groove 9, with its lower end protruding from the support groove 9 and provided with a drive source, and its top periphery being inclined; a connecting block 82, disposed on the lower periphery of the slider 83 along the extension direction of the protruding end of the guide plate 6; and an end block 81, disposed at the end of the connecting block 82 away from the slider 83 and matching the guide groove 61.

[0024] When the electric slider 11 slides to the left along the electric slide rail 10, it drives the slider 83 to slide to the left. The guide groove 61 slides sequentially along the inclined surface-top surface-inclined surface of the slider 83 until the end block 81 slides into the guide groove 61. The end block 81 is engaged in the guide groove 61 and slides along the extension direction of the guide groove 61. The right end of the receiving plate 5 swings downward around the second axis 7 to unload the material into the first material frame. Similarly, when the electric slider 11 slides forward or backward along the electric slide rail 10, the receiving plate 5 rotates around the first axis 3 to unload the material into the second and third material frames, thus achieving the classification of items.

[0025] Specifically, when the drive source drives the slider 8 to slide its end block 81 to the left along the guide groove 61 at the middle protruding end, it will force the right end of the receiving plate 5 to swing downward around the connecting shaft assembly, thereby unloading the material into the "material frame one" located in this direction. When the drive source drives the slider 8 to slide its end block 81 forward or backward along the guide groove 61 at the side protruding end, it will force the receiving plate 5 to rotate around the connecting shaft assembly, thereby unloading the material into the "material frame two" and "material frame three" located in the corresponding directions, thereby realizing the three-way automatic sorting of materials. This application sets up a guide plate 6 with a specific "T"-shaped structure and guide groove 61, which cooperates with a sliding member 8 that can slide along it, to accurately convert the linear motion of the drive source into the swinging or rotating motion of the receiving plate 5 in different directions. This structure ingeniously combines a drive source (driving the sliding member to move) with a guide mechanism, realizing the sorting action of the receiving plate in three directions. The structure is compact, the control logic is simple, and it effectively reduces the complexity and manufacturing cost of the multi-directional sorting device, while improving sorting efficiency and reliability.

[0026] In one embodiment, the coupling assembly includes: a mounting plate 2, which is fixed to the lower side of the discharge end of the conveyor belt 1; a mounting plate 4, which is disposed on the lower side of the receiving plate 5; a shaft 7, which is rotatably disposed on the side wall of the mounting plate 4 along the width direction of the receiving plate 5; and a shaft 3, which is rotatably disposed on the mounting plate 2 and the shaft 7 respectively along the length direction of the receiving plate 5. Specifically, mounting plate 2 is fixed to the lower side of the discharge end of conveyor belt 1, mounting plate 4 is set to the lower side of receiving plate 5, shaft 7 is rotatably set on the side wall of mounting plate 4 along the width direction of receiving plate 5, and the two ends of shaft 3 are rotatably connected to mounting plate 2 and shaft 7 respectively along the length direction of receiving plate 5. This connection method makes shaft 3 and shaft 7 form a directional joint connection structure. The rotational cooperation of shaft 3 and shaft 7 enables the receiving plate 5 to both pitch and swing around the axis of shaft 3 (roughly corresponding to the length direction of the receiving plate) for unloading to the left, and to deflect and swing around the axis of shaft 7 (roughly corresponding to the width direction of the receiving plate) for unloading forward / backward. This provides a stable and reliable mechanical basis for the receiving plate 5 to achieve multi-degree-of-freedom, flexible and controllable swinging.

[0027] In one embodiment, the driving source includes: an electric slide rail 10, disposed on the base support surface, which matches the sliding trajectory of the slider 8; and an electric slider 11, the top of which is disposed vertically on the lower side of the slider 8, and the lower end of which slides along the electric slide rail 10.

[0028] Specifically, the driving source includes an electric slide rail 10 and an electric slider 11. The electric slide rail 10 is set on the support surface of the base, and its extension trajectory matches the trajectory of the slider 8 (i.e., matches the "T" shaped profile of the guide plate 6). The top of the electric slider 11 is connected to the lower side of the slider 8 in the vertical direction, and its lower end can slide along the electric slide rail 10.

[0029] In one embodiment, the cross-section of the guide groove 61 is V-shaped, U-shaped, or dovetail-shaped.

[0030] Specifically, V-grooves are simple to process and have good guiding properties; U-grooves have relatively low motion resistance; and dovetail grooves can better limit the displacement of the end block 81 of the sliding component 8 in the direction perpendicular to the groove opening, preventing derailment and increasing motion stability. Appropriate cross-sectional shapes can be selected based on different process and strength requirements.

[0031] In one embodiment, the trajectory of the electric slide rail 10 matches the top view shape of the guide plate 6 and includes three straight tracks corresponding to the three protruding ends of the guide plate 6, respectively.

[0032] Specifically, the laying trajectory of the electric slide rail 10 is precisely matched with the top-view "T" shape of the guide plate 6, including three straight tracks. These three straight tracks correspond to the extension directions of one central protruding end and two side protruding ends of the guide plate 6, respectively. By designing the trajectory of the electric slide rail 10 as three clearly defined straight tracks that match the shape of the guide plate 6, the movement path of the electric slider 11 is strictly limited, ensuring that the slider 8 can only move along the three preset sorting directions, avoiding malfunctions, and improving the accuracy of sorting actions and the reliability of system operation.

[0033] In one embodiment, the drive source further includes a control unit for controlling the movement of the electric slider 11 along the electric slide rail 10, the control unit being communicatively connected to the central controller of the sorting system.

[0034] Specifically, an independent control unit is set up and communicates with the central controller, so that this sorting conveyor belt can be integrated into a larger automated logistics system as a subsystem. The central controller can issue instructions to the control unit based on the upstream cargo information (such as barcode scanning results), and the control unit drives the electric slider 11 to move to the corresponding position, realizing fully automatic intelligent sorting linked with the information system, which greatly improves the automation level and processing capacity of the entire logistics system.

[0035] In one embodiment, the angle between the top peripheral inclined surface of the slider 83 and the horizontal plane is 30° to 60°.

[0036] Specifically, limiting the slope angle of the top of the slider 83 to between 30° and 60° is an optimized range. If the slope angle is too small (too gentle), the contact stress distribution between the slider 83 and the guide plate 6 in the support groove 9 may be poor, and the start-up response to the swinging action may be slightly slower. If the slope angle is too large (too steep), it may increase the motion resistance and wear. This angle range can ensure flexible and smooth driving of the guide plate 6 and the receiving plate 5 to swing, while taking into account the mechanical performance and durability of the structure.

[0037] In one embodiment, the slope of the bottom of each protruding end of the guide plate 6 gradually increases in the direction away from the support groove 9.

[0038] Specifically, the gradual slope design changes the lever arm or effect of the sliding block 81 at the end of the slider 8 as it slides in the guide groove 61, thus pushing the receiving plate 5 to swing. In particular, a smaller slope is set near the support groove 9 (the starting point of the swing) to make the swing start smoother. A larger slope is set far from the support groove 9 (the end of the swing) to allow the receiving plate 5 to achieve a faster tilting speed or a larger tilting angle at the unloading point, ensuring that the material can be thoroughly and quickly thrown into the material frame, preventing material residue or poor slippage, and optimizing the unloading performance.

[0039] In one embodiment, the conveyor belt 1 is also equipped with a scanner for identifying cargo information, and the scanner is communicatively connected to the central controller of the sorting system.

[0040] Specifically, a scanner (such as a barcode scanner or a visual recognition camera) is also installed on conveyor belt 1 to identify information about the goods being transported (such as destination code, type, etc.). This scanner is also connected to the central controller of the sorting system. The addition of the scanner constitutes a complete information perception link. The goods information acquired by the scanner is uploaded to the central controller in real time. Based on this, the central controller decides which direction the goods need to be sorted and issues instructions to the control unit of the drive source. This realizes closed-loop automation from "goods identification" to "sorting execution", which is the core of realizing intelligent and information-based sorting, greatly improving the accuracy and efficiency of sorting and reducing manual intervention.

[0041] In one embodiment, the pressure sensor is disposed on the upper surface of the receiving plate 5 and is used to detect the load weight on the receiving plate 5; the control module is connected to the pressure sensor and the drive source signal and is configured to: The system receives the weight signal from the pressure sensor and controls the speed of the sliding member 8 driven by the drive source according to the preset weight-swing speed mapping relationship, so that the swing speed of the receiving plate 5 is negatively correlated with the current load weight.

[0042] Specifically, a pressure sensor is installed on the upper surface of the receiving plate 5 to detect the weight of the material carried on the receiving plate 5 in real time. The system also includes a control module, which is connected to the pressure sensor and the drive source (electric slider control unit). The control module is pre-configured with a "weight-swing speed mapping relationship" program. Its workflow is as follows: receiving the weight signal sent by the pressure sensor → calculating the recommended swing speed corresponding to the current load weight according to the preset mapping relationship → sending a control signal to the drive source to adjust the moving speed of the electric slider 11, thereby controlling the movement speed of the sliding component 8. The final effect is that the swing speed of the receiving plate 5 is "negatively correlated" with the current load weight, that is, the heavier the goods, the slower the swing speed; the lighter the goods, the faster the swing speed. By sensing the load through a pressure sensor and dynamically adjusting the swing speed through a control module, a slower swing speed can prevent materials from being thrown out or impacting the equipment due to excessive inertia, thus protecting the safety of goods and equipment. It also avoids system vibration and noise caused by the rapid swing of heavy objects. For lightweight goods, a faster swing speed can shorten the sorting cycle and improve overall efficiency. This makes the sorting action no longer fixed, but can be automatically adjusted according to the actual situation, thus improving the intelligence level and applicability of the equipment.

[0043] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
