Description

Technical Field

[0001] The invention relates to the technical field of logistics loading and unloading, and in particular to a loading and unloading machine for loading and unloading goods. Background Art

[0002] In today's logistics industry, there have always been many problems that need to be solved in the cargo loading and unloading process. In the stage of centralized stacking of goods after the assembly line is packed, if it relies on manual loading, its low efficiency is obvious. On the one hand, the speed of manual handling of goods is far slower than that of mechanical automation operation. To carry the same amount of goods, the time required for manual labor is much longer than that of mechanical equipment. When faced with a large amount of goods, this efficiency difference becomes more and more obvious, which can easily lead to the pile-up of goods on the site, but due to insufficient manpower, the loading cannot be completed, which in turn delays the subsequent transportation process and affects the timeliness of the entire supply chain. On the other hand, manual operation also requires a lot of manpower costs. Enterprises need to pay high manpower costs, and spend time and energy in the recruitment, training, and management of loading and unloading workers. At the same time, manual loading and unloading is labor-intensive and workers are prone to fatigue, which not only reduces work efficiency, but also may cause damage to goods or safety accidents due to fatigue operation, increasing the potential risks and costs of enterprises.

[0003] Although forklifts have improved the mechanization level of cargo loading to a certain extent, they have also exposed many defects in actual use. First of all, there is a high risk factor in forklift operation. During the operation of the forklift, due to factors such as unstable cargo stacking and improper operation, accidents such as rollover and cargo falling are prone to occur, posing a serious threat to the personal safety of operators and other surrounding personnel. Due to the limited length and insertion depth of the forklift's fork, for some large trucks, it is impossible to place the cargo completely and stably in the designated position inside the carriage, resulting in loose cargo loading, low space utilization, and even some cargo cannot be loaded, affecting transportation efficiency. In addition, forklifts are also lacking in operational flexibility. For some special-shaped, easily damaged, or cargo that requires fine steering and sorting, it is difficult for forklifts to perform delicate and accurate operations like manual labor, and they cannot meet the needs of screening and steering of cargo before loading, which can easily cause damage or misloading of cargo, causing unnecessary losses to the company.

[0004] In addition, the existing loading and unloading processes and equipment are not smooth in connection with the assembly line packaging process. Assembly line packaging is usually an efficient and continuous operation mode, but the subsequent loading and unloading process is difficult to match its rhythm, resulting in the goods not being able to enter the loading and unloading process in a timely and rapid manner after packaging is completed, and being piled up in the middle link, occupying additional storage space, increasing storage costs, and disrupting the rhythm of the entire production logistics, making the coordination between the various links worse, and making it difficult to achieve efficient and smooth logistics operations.

[0005] In summary, at present, the goods loading and unloading process faces many challenges such as low efficiency of manual loading, many safety hazards and limited application range of forklifts, and poor connection of the loading and unloading process. These problems seriously restrict the overall efficiency and service quality of the logistics industry. It is urgent to develop a new type of loading and unloading machine to overcome these difficulties in order to achieve efficient, safe, accurate and automated goods loading and unloading and meet the growing development needs of the modern logistics industry. For this reason, a loading and unloading machine for goods loading and unloading is provided to solve the above problems. Summary of the Invention

[0022] As Figure 1 shown, a loading and unloading machine for goods loading and unloading includes a frame 1. A moving plate 2 is slidably mounted on the top of the frame 1. A pushing device is provided between the moving plate 2 and the frame 1. A translation device 3 is mounted at both ends near the bottom of the frame 1. A gantry 4 is mounted at the rear end of the top of the frame 1. A pushing device 5 is slidably arranged up and down in the gantry 4. A loading device 9 is provided at the front end of the frame 1. A feeding device 8 is provided on the side of the loading device 9. A feeding device 6 is provided between both sides of the frame 1. A supporting roller 10 is provided between the moving plate 2 and the loading device 9. The materials pushed in from the loading device 9 fall onto the top of the moving plate 2 after passing through the feeding device 6.

[0023] In the above technical solution, the goods to be loaded are stacked above the moving plate 2. The moving plate 2 is pushed by the pushing device. The moving plate 2 carrying the goods is pushed into the carriage. At this time, the pushing device 5 moves downward and blocks in front of the goods. At this time, the pushing device drives the moving plate 2 to reset. The goods are blocked in the carriage by the pushing device 5, and the moving plate 2 is withdrawn from the bottom of the goods, leaving the goods in the carriage.

[0024] Refer to Figure 3 shown, rollers 21 are evenly distributed on the surface of the moving plate 2. The rollers 21 are rotatably arranged. Some of the rollers 21 protrude partially above the moving plate 2. The goods to be loaded are supported by the rollers 21. Some of the rollers 21 protrude downward outside the moving plate 2. These rollers 21 roll and support on the top of the frame 1 and support the moving plate 2 to separate from the frame 1.

[0025] In the above technical solution, the sliding of the moving plate 2 is supported by rolling through the rollers 21, reducing the moving resistance of the moving plate 2.

[0026] Part of the roller 21 is supported on the bottom of the goods, facilitating the withdrawal of the moving plate 2 from the bottom of the goods.

[0027] Refer to Figure 1 and Figure 4 As shown, a rack 7 is provided inside the gantry 4. The rack 7 is arranged vertically, and the pushing device 5 is adapted to the rack 7.

[0028] Refer to Figure 4 and Figure 5 As shown, the pushing device 5 includes a movable frame 501. Both ends of the movable frame 501 are inserted into the gantry 4. Pulleys 502 are installed at both ends and the front and rear end faces of the movable frame 501. The pulleys 502 are in contact with the inner wall of the gantry 4.

[0029] In the above technical solution, the position of the movable frame 501 is adjusted by the cooperation of the gear and the rack. When loading the goods, the movable frame 501 moves upward to avoid affecting the movement of the moving plate 2 carrying the goods into the carriage. After the moving plate 2 is pushed in place, the movable frame 501 moves downward, and the push plate 508 is pushed out to act on the goods to complete the limiting of the goods. At this time, the moving plate 2 is withdrawn to complete the separation.

[0030] Refer to Figure 3 As shown, the push plate 508 is connected to a guide rod 509. A linear bearing 510 is provided between the guide rod 509 and the movable frame 501.

A sliding plate 33 is provided inside the base plate 31. A notch 34 for the hydraulic moving rod 32 to retreat is provided in the middle of the sliding plate 33. A hydraulic support rod 35 is installed inside the frame 1. The telescopic end of the hydraulic support rod 35 is fixed to the sliding plate 33. Both ends of the hydraulic moving rod 32 are fixed to the sliding plate 33.

[0033] In the above technical solution, the hydraulic support rod 35 can adjust the height of the frame 1 to facilitate the sliding of the moving plate 2 into the carriage, and the sliding plate 33 can slide along the base plate 31 to facilitate the alignment of the moving plate 2 with the carriage.
