Description

Technical Field

[0001] This invention relates to the field of logistics conveying equipment technology, and in particular to an intelligent lifting and conveying device for logistics transportation. Background Technology

[0002] In the logistics and transportation sector, goods need to be transported from logistics warehouses to truck compartments and then transferred by trucks. Traditional loading and unloading methods mainly rely on manual handling or the use of fixed-length conveyors combined with forklifts. Manual handling is not only inefficient but also poses safety hazards. Fixed conveyors, due to their non-adjustable length and position, cannot penetrate deep into the truck compartment, often requiring manual secondary handling and stacking inside the truck compartment. This results in low automation and difficulty in adapting to the needs of different vehicle models and stacking depths.

[0003] Currently, most warehouses use a transitional conveyor system, which involves setting up a fixed-length roller or belt conveyor on the platform, connecting one end of it to the warehouse's outbound port. Goods are then transported by the conveyor, shortening the distance for manual handling. However, once the goods are delivered to the end of the conveyor, workers still need to perform subsequent operations inside the vehicle. The conveyor's speed is limited by the speed at which workers inside the vehicle handle and stack goods, which can easily lead to goods piling up at the end of the conveyor. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of low automation and reliance on manual operation inside the vehicle in existing logistics transportation devices, and to propose an intelligent lifting and conveying device for logistics transportation.

[0009] Preferably, the transverse movement mechanism includes a transverse movement guide rail and a transverse movement screw disposed on the surface of the base. A transverse movement platform is slidably connected to the transverse movement guide rail. The upper surface of the transverse movement platform is fixedly connected to the lifting conveyor belt.

[0010] Preferably, the material handling assembly includes a mounting base, a material handling push cylinder is provided in the mounting base, an installation strip is fixedly connected to the side of the material handling push cylinder facing the adjusting conveyor belt, a blocking push cylinder is fixedly installed on the upper surface of the installation strip, and a material handling push plate is fixedly connected to the output end of the blocking push cylinder through the installation strip.

[0011] Preferably, the telescopic frame is arranged in a scissor-like configuration, and multiple main limiting rods are rotatably connected between the telescopic frames. Multiple legs are installed on the outer side wall of the telescopic frame, and movable wheels are installed at the bottom of the legs. The legs are evenly spaced at the ends and middle of the outer side wall of the telescopic frame.

[0012] Preferably, the secondary deployment assembly includes a linkage group, the end of which is rotatably connected to the end of the drive roller group, and the connecting end of which is fixedly connected to the end of the auxiliary roller group.

[0013] Preferably, the first-stage deployment assembly includes multiple synchronous pulleys and driven pulleys. The synchronous pulleys are rotatably mounted at the top connection points of each scissor arm in the telescopic frame, and the driven pulleys are rotatably mounted at the middle connection points of each scissor arm in the telescopic frame. The synchronous pulleys, driven pulleys, and conveyor motor are connected by a synchronous belt.

[0014] Preferably, the outer walls of the drive roller and the auxiliary roller are provided with gaps at equal intervals, and the gaps of the drive roller and the auxiliary roller are alternately arranged.

[0015] Preferably, the ejection assembly includes a conveying screw and a conveying limiting rod installed in the groove. A slider is installed on the conveying screw and the conveying limiting rod. A conveying motor is installed at the end of the conveying screw. A push block is installed above the slider. A through hole is opened on the upper surface of the push block. A lifting limiting rod is slidably connected in the through hole. A return spring is provided on the outer wall of the lifting limiting rod. A feeding push plate is provided above the lifting limiting rod. The bottom end of the lifting limiting rod passes through the through hole and is slidably connected to the limiting slide groove. A rectangular groove matching the inclined surface of the palletizing actuator is opened at the bottom of the feeding push plate. A drag-reducing roller is rotatably connected in the rectangular groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. By setting up a palletizing assembly, this invention utilizes a horizontally movable lifting conveyor belt and a material picking mechanism to actively penetrate into the interior of the freight car, realizing fully automated palletizing operations from far to near and from low to high within the freight car. This completely changes the traditional mode that requires manual unloading inside the freight car or reliance on a fixed-length conveyor, greatly improving palletizing efficiency, space utilization, and operational safety, while significantly reducing labor intensity and labor costs.

[0018] 2. By setting up a scissor-type telescopic frame, a first-stage deployment component and a second-stage deployment component, the present invention enables the adaptive conveyor belt to automatically adjust its length according to the cargo stacking position, and compensates for the support gap in real time through auxiliary rollers during the telescopic process, ensuring smooth and jam-free cargo transportation, and significantly improving the flexibility and reliability of the conveying system.

[0019] 3. By setting up a structure in which the drive rollers and auxiliary rollers are arranged in an alternating manner, this invention ensures that the adaptive conveyor belt can provide a continuous, uniform and complete support plane for the goods in any extension or retraction state. When the telescopic frame is extended, the distance between the drive rollers will increase. At this time, the auxiliary rollers driven by the secondary extension component move to the center position of the gap between the drive rollers, forming an alternating and complementary support. This avoids the deformation, tilting or jamming of goods (especially cardboard boxes with insufficient bottom rigidity) due to local suspension, and ensures that goods of various sizes can be transported smoothly and steadily to the target position.

[0032] Example, refer to Figures 1 to 8 A smart lifting and conveying device for logistics transportation includes a base 1 and a warehouse conveyor belt 2 located on the surface of the base 1. A buffer pad 3 is provided at the end of the base 1 away from the warehouse conveyor belt 2 to protect the base 1. An adjusting conveyor belt 4 is provided on the surface of the base 1. The adjusting conveyor belt 4 is set perpendicular to the warehouse conveyor belt 2 and is used to transfer the box conveyed by the warehouse conveyor belt 2 to a state aligned with the vertical handling component. A transverse movement mechanism is provided on the side of the adjusting conveyor belt 4 away from the warehouse conveyor belt 2. A lifting conveyor belt 5 is provided on the transverse movement mechanism. A material picking component is provided at the input end of the lifting conveyor belt 5. A palletizing assembly is provided at the output end of the lifting conveyor belt 5. The palletizing assembly is composed of an adaptive conveyor belt and a vertical handling component.

[0033] The adaptive conveyor belt includes a fixed support 6, a conveyor motor on the inner wall of the fixed support 6, a telescopic frame 7 on the outer wall of the fixed support 6, multiple drive rollers 8 between the telescopic frames 7, a secondary unfolding assembly at the end of the drive roller 8, a primary unfolding assembly at the end of the secondary unfolding assembly, and an auxiliary roller 9 on the inner side of the primary unfolding assembly. The adaptive conveyor belt can automatically adjust the length of the conveying path according to the stacking position of the goods to achieve efficient and flexible conveying.

[0034] The vertical handling assembly includes a lifting frame 10 installed at the end of the telescopic frame 7. One end of the lifting frame 10 is fixedly connected to the output end of the telescopic frame 7. Universal wheels 12 driven by a drive unit are provided on both sides of the lifting frame 10. A palletizing actuator 13 is provided inside the lifting frame 10. The side of the palletizing actuator 13 closest to the telescopic frame 7 is provided with an inclined surface. The side of the palletizing actuator 13 away from the telescopic frame 7 is provided with a displacement sensor 11. The upper surface of the palletizing actuator 13 is provided with a limit groove and a recess in sequence. An ejection component is installed in the recess.

[0035] Furthermore, the transverse movement mechanism includes a transverse movement guide rail 14 and a transverse movement screw 15 disposed on the surface of the base 1. A transverse movement platform 16 is slidably connected to the transverse movement guide rail 14. The upper surface of the transverse movement platform 16 is fixedly connected to the lifting conveyor belt 5. The transverse movement screw 15 is threadedly connected to the bottom of the transverse movement platform 16. A transverse movement motor is provided at the end of the transverse movement screw 15. The transverse movement motor drives the screw to rotate, which can drive the transverse movement platform 16 to move horizontally along the transverse movement guide rail 14, thereby achieving precise positioning of the lifting conveyor belt 5 and the stacking location inside the carriage.

[0036] Furthermore, the material handling assembly includes a mounting base 17, which is equipped with a material handling push cylinder. The material handling push cylinder is fixedly connected to a mounting strip 18 on the side facing the adjusting conveyor belt 4. A blocking push cylinder is fixedly installed on the upper surface of the mounting strip 18. The output end of the blocking push cylinder passes through the mounting strip 18 and is fixedly connected to a material handling push plate 19. The material handling push cylinder can push the mounting strip 18, the blocking push cylinder on the mounting strip 18, and the material handling push plate 19 to approach the goods. The blocking push cylinder drives the material handling push plate 19 to descend, thereby realizing the grabbing and pushing of the goods.

[0037] Furthermore, the telescopic frame 7 is arranged in a scissor-like manner, and multiple main limiting rods 20 are rotatably connected between the telescopic frames 7. Multiple support legs are installed on the outer side wall of the telescopic frame 7, and movable wheels are installed at the bottom of the support legs. The support legs are evenly spaced at the ends and middle of the outer side wall of the telescopic frame 7. The main limiting rods 20 are used to prevent the frame from tilting during the telescopic process, and to ensure the structural rigidity and movement stability of the telescopic frame 7 during the unfolding and retraction process.

[0038] Furthermore, the secondary deployment assembly includes a connecting rod group 21, with both ends of the connecting rod group 21 rotatably connected to the ends of the drive roller group 8, and the central connecting end of the connecting rod group 21 fixedly connected to the end of the auxiliary roller group 9. During the process of the telescopic frame 7 moving and deploying synchronously, the auxiliary roller 9 rises synchronously under the action of the connecting rod group 21 to compensate for the gap after the drive roller group 8 is deployed.

[0039] The further advantage of adopting the above is that, under the action of the linkage group 21, the auxiliary roller 9 can move in real time to follow the expansion of the telescopic frame 7, promptly filling the support gap caused by the expansion and contraction of the telescopic frame 7, avoiding the tilting or jamming of goods due to local suspension, and significantly improving the stability and adaptability of the conveying.

[0040] Furthermore, the first-stage deployment assembly includes multiple synchronous pulleys 22 and driven pulleys 23. The synchronous pulleys 22 are rotatably mounted at the top connection points of the scissor arms in the telescopic frame 7, and the driven pulleys 23 are rotatably mounted at the middle connection points of the scissor arms in the telescopic frame 7. The synchronous pulleys 22, driven pulleys 23, and conveyor motor are connected via synchronous belts. During deployment, because the distance between the top connection points and the middle connection points of adjacent scissor arms remains constant, when the synchronous pulleys 22 and driven pulleys 23 are connected to the conveyor motor via synchronous belts, it can ensure that all drive rollers 8 always operate synchronously, making power transmission continuous and reliable and avoiding transmission failure.

[0041] The further advantage of adopting the above is that, while maintaining the conveying function during the opening and closing process, the relative positions between specific points on the scissor arm remain unchanged. By using synchronous belt drive, it ensures that the speed and direction of all drive units are always consistent during the extension and retraction process, eliminating the problems of asynchrony, belt vibration or derailment that may be caused by changes in length, and making the power transmission more stable and reliable.

[0042] Furthermore, the outer walls of the drive roller 8 and the auxiliary roller 9 are provided with gaps at equal intervals. The gaps of the drive roller 8 and the auxiliary roller 9 are alternately arranged. The auxiliary roller 9 can immediately compensate for the gaps between the drive rollers 8 during the unfolding process, while ensuring sufficient and uniform support for the goods and preventing the goods from getting stuck or overturning.

[0043] The further advantage of the above-mentioned method is that the staggered roller gaps in the drive roller 8 and the auxiliary roller 9 allow the drive roller 8 and the auxiliary roller 9 to perform deployment actions simultaneously. Under the combined action of the primary deployment assembly and the secondary deployment assembly, when the gap between the drive rollers 8 gradually increases during the deployment process but has not yet reached the critical value that affects the support, the auxiliary roller 9 has been fully deployed under the drive of the connecting rod assembly 21, rising from the roller gap of the drive roller 8 to a state parallel to the drive roller 8. This ensures that the bottom surface of the cargo always receives continuous and uniform support throughout the entire extension range from the initial width to the maximum width, thereby effectively distributing the load and preventing the cargo from deforming or becoming unstable.

[0044] Furthermore, the ejector assembly includes a conveying screw 24 and a conveying limit rod 25 installed in the groove. A slider 26 is installed on the conveying screw 24 and the conveying limit rod 25. A conveying motor is installed at the end of the conveying screw 24. A push block 27 is installed above the slider 26. A through hole is opened on the upper surface of the push block 27. A lifting limit rod 28 is slidably connected in the through hole. A return spring is provided on the outer side wall of the lifting limit rod 28. A discharge push plate 29 is provided above the lifting limit rod 28. The bottom end of the lifting limit rod 28 passes through the through hole and is slidably connected to the limiting slide groove. A rectangular groove matching the inclined surface of the palletizing actuator 13 is opened at the bottom of the discharge push plate 29. A resistance-reducing roller 30 is rotatably connected in the rectangular groove.

[0045] It should be noted that the limiting groove guides the lifting limiting rod 28. When the unloading push plate 29 rises or falls along the inclined plane, the lifting limiting rod 28 slides along the limiting groove to prevent the unloading push plate 29 from deviating.

[0046] The further advantage of the above is that the ejection assembly drives the slider 26 to move via the conveying screw 24 to achieve the ejection and retraction actions. During the extension process, the unloading push plate 29 achieves low-resistance translation and rise on the palletizing actuator 13 through the cooperation of the drag-reducing roller 30 and the inclined plane, and then ejects the goods. The return spring can provide a return force for the unloading push plate 29.

[0047] When using this invention, the truck opens its cargo compartment and begins to reverse until the rear of the cargo compartment contacts the buffer pad 3. Then, the operator activates the device.

[0048] After the device is turned on, the drive unit controls the casters 12 to move forward in a straight line. Since the lifting frame 10 is fixedly connected to the telescopic frame 7, the lifting frame 10 moves and drives the telescopic frame 7 to unfold synchronously. The drive roller 8 unfolds synchronously with the frame. At the same time, the secondary unfolding component drives the auxiliary roller 9 to compensate for the gap. Finally, the lifting frame 10 and the palletizing actuator 13 move to contact the inner wall of the truck compartment. During this process, the secondary unfolding component can compensate for the support gap caused by the extension and contraction of the frame in a timely manner, maintain continuous and uniform support for the box, and prevent the goods from tilting or getting stuck.

[0049] When the lifting frame 10 contacts the inner wall of the carriage, the displacement sensor 11 uploads a contact signal, and the control system instructs the caster wheel 12 to move backward a distance of one cargo unit, and the device then enters the conveying process.

[0050] During the conveying process, the warehouse conveyor belt 2 continuously transports the boxes to the regulating conveyor belt 4, achieving automated connection and supply with the source of goods. The regulating conveyor belt 4 transfers and aligns the goods to the input end of the vertical handling component. Subsequently, the picking pusher cylinder pushes the mounting strip 18 to move behind the goods box, and the blocking pusher cylinder then drives the picking pusher plate 19 to descend. During the resetting process of the picking pusher cylinder, it drives the picking pusher plate 19 to push the goods to the lifting conveyor belt 5. After being lifted by the lifting conveyor belt 5, the goods enter the adaptive conveyor belt. The conveyor motor drives all drive rollers 8 to always maintain synchronous and unidirectional operation through the synchronous pulley 22, driven pulley 23 and synchronous belt in the first-stage unfolding component, ensuring continuous and uninterrupted power transmission, and finally transporting the goods to the vertical handling component.

[0051] The vertical transport assembly receives the goods via the palletizing actuator 13 and adjusts them to a suitable height via the transmission mechanism in the lifting frame 10. Subsequently, the transport motor drives the transport screw 24 to rotate, causing the slider 26 to move horizontally along the transport limit rod 25. The push block 27 above the slider 26 moves synchronously with the slider 26. The drag-reducing roller 30 at the bottom of the unloading push plate 29 rolls along the inclined surface of the palletizing actuator 13. Under the guidance of the inclined surface, the unloading push plate 29 moves horizontally with the slider 26 and rises along the inclined surface, finally pushing the goods to the palletizing position. After the unloading action is completed, the transport screw 24 drives the slider 26 to reset. During the reset process of the slider 26, the movable push plate passes through the inclined surface again, causing the drag-reducing roller 30 to descend along the inclined surface. Under the action of the reset spring, it automatically returns to its original position, completing the unloading operation.

[0052] Subsequently, the transverse mechanism drives the transverse lead screw 15 through the transverse motor, which drives the lifting conveyor belt 5 to move horizontally smoothly and accurately. At the same time, the drive unit controls the universal wheels 12 to move synchronously, so that the whole machine is aligned with the next stacking position in the truck bed, and continues to perform subsequent unloading actions, realizing an automated stacking process from far to near and from low to high in the truck bed.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
