Description

Technical Field

[0001] The present invention specifically relates to the technical field of automatic loading, and in particular to an automatic loading system. Background Art

[0002] With the development of express delivery and logistics industries, an automatic loading system is needed. At present, traditional loading devices use manual handling and loading, manual forklift loading, conveyor to transport materials to the inside of the container, and manual stacking in the container. In short, it is all manual loading. The disadvantage of this traditional operation mode is that the work intensity of the operators is high, and the proficiency and working status of the operators affect the quality of the work. In pure manual loading, the material information is all controlled by the personnel, which is prone to errors, and the data cannot be efficiently managed after shipment.

[0003] When loading, the stability of the vehicle is particularly important. However, the current traditional loading equipment needs to repeatedly debug the position of the truck when loading the truck, which takes a long time. After the debugging is completed, it is necessary to adjust the distance between the truck and the platform, and to ensure that the height between the rear of the vehicle and the platform is lifted and adjusted, which will cause the vehicle to tilt. When loading, the vehicle will shake, and the shaking of the vehicle will cause the loaded goods to tip over or fall, and the loading efficiency cannot be effectively guaranteed.

[0004] After searching, Chinese patent publication number CN202320524586.6 discloses a robot palletizing and loading device; comprising a loading platform, a ground and a box vehicle, the box vehicle walking on the ground, the loading platform fixed on the ground, a loading box fixed on the box vehicle, an upper conveying platform fixed on the upper surface of the loading platform, a movable lower conveying platform provided below the upper conveying platform, and a plurality of support plates fixed at both the front and rear ends of the lower conveying platform;

[0005] Although the structure in the above patent can achieve the effect of automatic loading, when adjusting the position of the truck, the driver needs to adjust the position between the vehicle and the platform many times, and then adjust the height of the rear of the vehicle through the cylinder to ensure that the crawler trolley in the lifting device can accurately enter the vehicle. In this way, when loading, the vehicle will shake, which will cause the loaded goods to tilt or fall, and the placement of the goods cannot be effectively guaranteed;

[0006] In view of the above situation, we provide an automatic loading system. In this device, when the truck is loading, the guide frame is used to effectively ensure the accurate position of the vehicle. When the truck is reversing, the wheel contacts the sliding assembly, so that the stop slider slides backward along the first slot opened on the carrier. During the sliding of the stop slider, the toothed plate at the bottom of the stop slider cooperates with the gears at both ends of the rotating shaft, so that the rotating shaft drives the first top plate to flip through the fixed rod, so that the first top plate flips from a vertical state to a horizontal state. When the first top plate is in the horizontal state, it is parallel to the bottom of the vehicle. During the backward sliding of the stop slider, the connecting card plate is driven to contact the movable card plate, and the movable card plate is squeezed by the inclined angle set on the connecting card plate, so that the movable card plate is tilted upward. During the upward tilting of the movable card plate, the squeezing rods on both sides of the movable card plate squeeze the air The elastic plate in the cavity allows the top of the elastic plate to penetrate to the outside of the second slot. After the sliding assembly stops moving, the vehicle positioning is completed, and then the first top plate in the horizontal state is lifted upward by two lifting cylinders, and the second lifting assembly at the end of the guide frame is lifted upward at the same time to adjust the height of the vehicle and ensure that the vehicle is flush with the bottom of the dust cover shell, which is convenient for the loading trolley to enter the vehicle; after the vehicle is loaded, the lifting cylinder drives the first top plate to descend, and the second lifting assembly descends to achieve the vehicle The lowering of the carrier, when the vehicle moves forward, the wheels press down the elastic plate during the movement, and the elastic plate squeezes the squeezing rod to achieve the movable card plate to tilt up again and separate from the connecting card plate, and the stop slider moves forward through the spring set on the slide rod. At this time, the tooth plate is engaged with the gear to achieve the rotation of the first top plate to a vertical state, so that the vehicle can pass smoothly. Summary of the invention

When the first top plate is in the horizontal state, it is parallel to the bottom of the vehicle. During the sliding process of the stop slider backward, the connecting card plate is driven to contact the movable card plate, and the movable card plate is squeezed by the inclined angle set on the connecting card plate, so that the movable card plate is tilted upward. During the process of the movable pallet tilting upward, the extrusion rods on both sides of the movable pallet squeeze the elastic plate in the cavity, so that the top of the elastic plate passes through the outside of the second slot. After the vehicle is loaded, the jacking cylinder drives the first top plate to descend, and the second jacking assembly descends, so that the vehicle is lowered onto the carrier. When the vehicle moves forward, the wheels press down the elastic plate during movement, and the elastic plate squeezes the extrusion rods, so that the movable pallet tilts upward again and separates from the connected pallet.

When the vehicle moves on the carrier 30, the rear wheel contacts the roller 311, and the roller 311 drives the stop slider 310 to slide backward along the first slot 301 opened on the carrier 30.

The sliding assembly 31 can effectively ensure accurate positioning of the vehicle.

[0048] Furthermore, after the vehicle stops moving, the first top plate 60 in the horizontal state is lifted upward by the lifting cylinder 64, so that the first top plate 60 contacts the bottom of the vehicle, and at the same time, the driving motor 51 drives the screw rod 52 to rotate, so that the first moving shaft 53 slides forward, and the first support frame 54 and the second support frame 55 are collected under the cooperation of the connecting shaft 58, and at the same time, the second moving shaft 56 at the bottom of the first support frame 54 slides forward to realize the upward support of the second top plate 50, and the bottom of the vehicle cargo compartment is moved to be flush with the bottom of the dust cover shell 7 through the first top plate 60 and the second top plate 50, so as to facilitate the entry of the loading trolley 14;

[0049] In this embodiment, a second lifting assembly 5 is provided at the end of the guide frame 2; the second lifting assembly 5 includes a second top plate 50; the bottom of the second top plate 50 is movably connected to the rotating shaft at the top of the first support frame 54 and the first movable shaft 53 at the top of the second support frame 55 through a mounting seat, wherein a screw rod 52 is installed in the middle of the first movable shaft 53; one end of the screw rod 52 is connected to the driving motor 51, and the first support frame 54 and the second support frame 55 are provided in two groups and are symmetrically arranged; the end of the first support frame 54 away from the second top plate 50 is slidably connected to the bottom plate 57 through the second movable shaft 56; the end of the second support frame 55 away from the second top plate 50 is movably connected to the bottom plate 57 through the rotating shaft;

[0054] The depalletizing robot 11 calculates the loading model based on AI and detects the cargo type and arrangement order through 3D visual inspection. If the type does not match, the depalletizing robot 11 will place the cargo on a spare pallet. The correct cargo type will be transmitted in sequence through the telescopic power conveyor line 12. The LED display screen 9 automatically counts the current loading progress and product information. When it is close to completion, it will give a voice reminder of the remaining quantity to be loaded. After loading is completed, the voice prompts the vehicle to leave the loading area.

[0055] The working principle of the present invention is as follows: when in use, the vehicle is reversed backward along the inner sides of the two guide frames 2 installed on the ground 1. When the vehicle moves on the carrier 30, the rear wheel contacts the roller 311, and the roller 311 drives the stop slider 310 to slide backward along the first slot 301 opened on the carrier 30. At the same time, the toothed plate 313 integrally provided at the bottom of the first slot 301 drives the gears 38 at both ends of the rotating shaft 34 to rotate, and the fixed rod 61 installed in the middle of the rotating shaft 34 drives the first top plate 60 to flip upward. When the stop slider 310 stops sliding, the fixed rod 61 in the horizontal state rotates to the vertical state, and the first top plate 60 rotates from the vertical state to the horizontal state.

[0056] When the stop slide block 310 slides backward, the spring 26 sleeved on the squeeze slide bar 37 is squeezed, and the connecting card plate 312 between the two stop slide blocks 310 moves backward at the same time, and the connecting card plate 312 contacts the movable card plate 32 in the first rectangular groove 41 at the end of the first slot 301, and the inclined surface on the connecting card plate 312 tilts the movable card plate 32 upward. In the process of the movable card plate 32 tilting upward, the squeezing rods 320 on both sides squeeze the elastic plate 35 installed at the end of the cavity 303, so that the top of the elastic plate 35 passes through the outside of the second slot 302 to leak out;

[0057] When the stopper slider 310 in the sliding assembly 31 stops sliding, the cooperation between the roller 311 and the wheel effectively prevents the vehicle from moving in transition and damages the stopper slider 310 . The sliding assembly 31 effectively ensures accurate positioning of the vehicle.

[0058] After the vehicle stops moving, the first top plate 60 in the horizontal state is lifted upward by the lifting cylinder 64, so that the first top plate 60 contacts the bottom of the vehicle, and at the same time, the driving motor 51 drives the screw rod 52 to rotate, so that the first moving shaft 53 slides forward, and the first support frame 54 and the second support frame 55 are collected with the cooperation of the connecting shaft 58, and at the same time, the second moving shaft 56 at the bottom of the first support frame 54 slides forward to realize the upward support of the second top plate 50, and the bottom of the vehicle compartment is moved to be flush with the bottom of the dust cover shell 7 through the first top plate 60 and the second top plate 50, so as to facilitate the entry of the loading trolley 14;

[0059] During the reversing process, multiple AI automatic identification mechanisms 13 installed at the end of the dust cover 7 are used to effectively detect the switch status of the vehicle rear door, the distance between the end of the vehicle and the platform, and the space inside the vehicle compartment. During the loading process, the depalletizing robot 11 places the goods on the telescopic power transmission line 12 for transmission. The telescopic power transmission line 12 is connected with the AI ​​automatic sorting mechanism 10 to move goods of different sizes to the designated position through the loading trolley 14, so that goods of different sizes can be placed in an orderly manner.

[0060] The overall process of the loading system is as follows: the driver swipes the card to start, the vehicle type is automatically identified, AI generates the loading pattern, and unmanned loading is realized throughout the process. The vehicle is positioned, and mechanical guidance is used to connect the vehicle with the loading system. The lifting component is lifted so that the bottom of the cargo box is at the same height as the platform. There is an AI automatic recognition mechanism 13 to detect the distance between the end of the vehicle and the platform, and to detect the quick closing state of the rear door of the vehicle;

[0061] The depalletizing robot 11 calculates the loading model based on AI and detects the cargo type and arrangement order through 3D visual inspection. If the type does not match, the depalletizing robot 11 will place the cargo on a spare pallet. The correct cargo type will be transmitted in sequence through the telescopic power conveyor line 12. The LED display screen 9 automatically counts the current loading progress and product information. When it is close to completion, it will give a voice reminder of the remaining quantity to be loaded. After loading is completed, the voice prompts the vehicle to leave the loading area.
