Abstract
Description
Technical Field
[0001] This invention relates to the field of logistics transportation technology, and in particular to an automatic loading and unloading device for logistics transportation. Background Technology
[0002] With the rapid development of the logistics industry, problems such as rising labor costs, labor shortages, and tight warehouse space have become increasingly prominent. Traditional manual or forklift loading and unloading methods have gradually become bottlenecks affecting logistics efficiency. Especially with the widespread application of automated warehousing, picking, and packaging technologies, forklift or manual handling in loading and unloading areas seriously hinders the overall operational efficiency of the logistics system. In addition, increasingly stringent employee health and safety regulations have also prompted companies to pay more attention to the cleanliness, safety, and controllability of logistics processes. Against this backdrop, automated loading and unloading devices for logistics transportation have emerged, aiming to reduce manpower input, improve loading and unloading efficiency, shorten vehicle dwell time, and reduce logistics costs through automation technology, thereby enhancing the overall competitiveness of the supply chain.
[0003] In actual use, the existing device is connected to the conveyor belt for loading and unloading goods. However, when the goods are transported from the conveyor belt to the device, they are prone to shifting or even falling off the device due to inertia, resulting in poor performance. Therefore, an automatic loading and unloading device for logistics transportation is proposed. Summary of the Invention
[0004] The purpose of this invention is to solve the shortcomings of the prior art, where the device is connected to the conveyor belt for loading and unloading goods, but when the goods are transported from the conveyor belt to the device, they are prone to deviate or even fall off the device due to inertia, resulting in poor performance. Therefore, this invention proposes an automatic loading and unloading device for logistics transportation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic loading and unloading device for logistics conveying includes a device base. A conveying housing is rotatably connected to the upper part of the device base. A transition housing is rotatably connected to the upper part of the conveying housing. A combined buffer mechanism is provided on the upper part of the transition housing. The combined buffer mechanism includes a spring fixedly connected to the upper part of the transition housing. A connecting plate is fixedly connected to the upper part of the spring. A buffer transition plate is fixedly connected to the upper part of the connecting plate. Sliding rods are rotatably connected to both sides of the connecting plate. A damping housing is slidably connected to the lower part of the sliding rods. The transition housing is rotatably connected to the lower part of the damping housing. A damping cavity is provided inside the damping cavity. A movable head is slidably connected inside the damping cavity. A sliding rod is fixedly connected to the upper part of the movable head. A damping hole is provided on the upper part of the movable head. Sealing plates are provided at both ends of the damping cavity.
[0006] After the goods on the conveyor belt are fed into the device, they first slide onto the upper part of the buffer transition plate. After being impacted by the goods, the buffer transition plate moves downward in the vertical direction due to the goods, thereby compressing the spring to buffer the vertical kinetic energy. In the horizontal direction, the goods move the buffer transition plate, and the movement of the buffer transition plate causes the movable head to move inside the damping cavity. The damping medium inside the damping cavity passes through the damping hole under the movement of the movable head, thereby generating throttling resistance to consume the horizontal kinetic energy of the goods.
[0007] The above technical solution further includes: A telescopic rod is fixedly connected to the lower part of the connecting plate, and a transition shell is fixedly connected to the lower part of the telescopic rod.
[0008] A protective mechanism is fixedly connected to the upper part of the transition housing. The protective mechanism includes a second motor disposed on the upper part of the transition housing, and a protective component is disposed at the output end of the second motor.
[0009] The protective assembly includes a threaded rod at the output end of a second motor, which is rotatably connected to a transition housing. A transmission component is threadedly connected to the upper part of the threaded rod, and a guardrail is fixedly connected to the upper part of the transmission component. A slider is fixedly connected to the lower part of the transmission component, and a limit rod is slidably connected to the slider. The limit rod is fixedly connected to the transition housing. The second motor is a dual-head motor.
[0010] An adjustment mechanism is provided on the upper part of the device base. The adjustment mechanism includes an adjustment housing fixedly connected to the upper part of the device base. A third motor is provided inside the adjustment housing, and an adjustment component is provided at the output end of the third motor.
[0011] The adjustment assembly includes a worm gear located at the output end of a third motor, the worm gear being meshed with a worm wheel, the worm wheel being fixedly connected to a transmission gear, the transmission gear being meshed with a transmission rack, and a transition housing being rotatably connected to the upper part of the transmission rack.
[0012] The adjusting housing is fixedly connected to a limiting groove, and a transmission rack is slidably connected inside the limiting groove.
[0013] A first motor is provided on one side of the conveyor housing. A first transmission wheel is provided at the output end of the first motor. The first transmission wheel is driven by a transmission belt. The transmission belt is driven by a second transmission wheel. The second transmission wheel is rotatably connected to the conveyor housing. A main roller is fixedly connected to the side of the second transmission wheel near the conveyor housing. The main roller is driven by a loading and unloading belt. A driven roller is driven by the side of the loading and unloading belt away from the main roller. The driven roller is rotatably connected to the conveyor housing.
[0014] A cylinder is installed on the upper part of the base of the device, and a conveying housing is rotatably connected to the upper part of the cylinder.
[0015] The present invention has the following beneficial effects: 1. In this invention, after the goods on the conveyor belt are transported to the device, they first come into contact with the buffer transition plate set between the conveyor belt and the loading / unloading belt. After the goods come into contact with the buffer transition plate, in the vertical direction, the goods can drive the buffer transition plate to move downward, thereby driving the spring to compress and achieve vertical buffering of the goods. In the horizontal direction, the goods drive the buffer transition plate to move, and the movement of the buffer transition plate can drive the movable head to move inside the damping cavity. During the movement of the movable head, the damping medium inside the damping cavity generates throttling resistance through the damping hole at the top of the movable head, thereby buffering the goods in the horizontal direction. By setting a buffer transition plate between the loading / unloading belt and the conveyor belt, the initial kinetic energy of the goods due to inertia can be effectively reduced, effectively avoiding the positional deviation of the goods due to inertia, and improving the loading and unloading effect of the device.
[0016] 2. In this invention, the tilt angle of the loading and unloading belt can be adjusted by a cylinder located at the bottom of the conveyor housing, so that the device can adjust the conveying angle according to the weight of the goods being loaded and unloaded. The tilt angle of the buffer transition plate can also be adjusted by an adjustment mechanism located at the bottom of the transition housing, so as to effectively connect with the conveyor belt and ensure the stability of loading and unloading goods.

A conveying housing 3 is rotatably connected to the upper part of the device base 1. A transition housing 9 is rotatably connected to the upper part of the conveying housing 3. A combined buffer mechanism is provided on the upper part of the transition housing 9. The combined buffer mechanism includes a spring 19 fixedly connected to the upper part of the transition housing 9. A connecting plate 15 is fixedly connected to the upper part of the spring 19. A buffer transition plate 7 is fixedly connected to the upper part of the connecting plate 15. Sliding rods 21 are rotatably connected to both sides of the connecting plate 15. A damping housing 20 is slidably connected to the lower part of the sliding rods 21. The transition housing 9 is rotatably connected to the lower part of the damping housing 20. A damping cavity 23 is provided inside the damping housing 20. A movable head 22 is slidably connected inside the damping cavity 23. A sliding rod 21 is fixedly connected to the upper part of the movable head 22. A damping hole 24 is provided on the upper part of the movable head 22. Sealing plates are provided at both ends of the damping cavity 23. A telescopic rod 18 is fixedly connected to the lower part of the connecting plate 15. The transition housing 9 is fixedly connected to the lower part of the telescopic rod 18.
[0021] After the goods on the conveyor belt are fed into the device, they first slide to the upper part of the buffer transition plate 7. After the buffer transition plate 7 is impacted by the goods, in the vertical direction, the goods drive the buffer transition plate 7 to move downward, thereby compressing the spring 19 to buffer the vertical kinetic energy. In the horizontal direction, the goods drive the buffer transition plate 7 to move, and the movement of the buffer transition plate 7 drives the movable head 22 to move inside the damping cavity 23. The damping medium inside the damping cavity 23 passes through the damping hole 24 under the movement of the movable head 22, thereby generating throttling resistance to consume the horizontal kinetic energy of the goods.
[0022] A protective mechanism is fixedly connected to the upper part of the transition housing 9. The protective mechanism includes a second motor 16 set on the upper part of the transition housing 9. A protective component is set at the output end of the second motor 16. The protective component includes a threaded rod 17 set at the output end of the second motor 16. The threaded rod 17 is rotatably connected to the transition housing 9.

[0023] In this embodiment, after the goods on the conveyor belt are transported to the device, they first come into contact with the buffer transition plate 7 set between the conveyor belt and the loading / unloading belt 4. After the goods come into contact with the buffer transition plate 7, the goods can drive the buffer transition plate 7 to move downward in the vertical direction, thereby driving the spring 19 to compress and achieve vertical buffering of the goods. In the horizontal direction, after the goods come into contact with the buffer transition plate 7, the buffer transition plate 7 will move. The movement of the buffer transition plate 7 can drive the rotatably connected slide rod 21 to move. The movement of the slide rod 21 can drive the fixedly connected movable head 22 to move inside the damping cavity 23. During the movement of the movable head 22, the damping medium inside the damping cavity 23 will generate throttling resistance through the damping hole 24 at the top of the movable head 22, thereby buffering the goods in the horizontal direction. By setting the buffer transition plate 7 between the loading / unloading belt 4 and the conveyor belt, the initial kinetic energy of the goods due to inertia can be effectively reduced, and the positional deviation of the goods due to inertia can be effectively avoided, thereby improving the loading and unloading effect of the device.
[0024] By starting the second motor 16, the threaded rod 17 can be driven to rotate. The rotation of the threaded rod 17 drives the threaded transmission component 27 to move. During the movement of the transmission component 27, the slider 26 fixed at the bottom can slide synchronously along the limit rod 25, which effectively improves the movement stability of the transmission component 27. The movement of the transmission component 27 can drive the guardrail 8 to move, so that the device can flexibly adjust the protection range of the guardrail 8 according to the actual size of the goods, thereby ensuring the safety of loading and unloading the goods.

[0027] In this embodiment, the tilt angle of the loading and unloading belt 4 can be adjusted by the cylinder 10 located at the bottom of the conveyor housing 3, so that the device can adjust the conveying angle according to the weight of the goods being loaded and unloaded. The third motor 28 is started to drive the worm 29 to rotate. The rotation of the worm 29 drives the meshing worm wheel 30 to rotate. The rotation of the worm wheel 30 drives the fixed transmission gear 31 to rotate. The rotation of the transmission gear 31 drives the meshing transmission rack 32 to move. During the movement of the transmission rack 32, the sliding limit groove 33 ensures the stability of the transmission rack 32 during movement. The movement of the transmission rack 32 drives the rotatably connected transition housing 9 to rotate, thereby adjusting the tilt angle of the buffer transition plate 7, ensuring that the buffer transition plate 7 can effectively dock with the conveyor belt and improving the loading and unloading stability of the goods.
[0028] Starting the first motor 11 can drive the first transmission wheel 5 to rotate. The rotation of the first transmission wheel 5 can drive the second transmission wheel 6, which is connected by the transmission belt 12, to rotate.
