Description

Technical Field

[0001] The present invention relates to the technical field of cargo shipping, and in particular to an intelligent logistics loading and unloading system for pallet-free transportation. Background Art

[0002] Freight transportation refers to the process of transporting goods from one location to another through different modes of transportation. Goods need to be reasonably packaged to ensure their safety during transportation. Packaging standards and loading methods vary depending on the means of transportation, characteristics of the goods, and transportation distance. After the goods arrive at the destination, they need to be unloaded and delivered to the final destination.

[0003] The loading and unloading of cargo transportation includes warehouse stacking. The purpose of warehouse stacking is to store goods efficiently and orderly to save warehouse space as much as possible. Goods need to be reasonably classified and stacked according to the frequency, type, specification, etc. of outbound delivery, so that the most frequently used goods are located in a more accessible position to facilitate the extraction of items from the stack. Palletless transportation means that in the logistics process, goods are directly loaded, transported and unloaded by means of transportation without using pallets as the basic carrier. Compared with pallet transportation, this method reduces the dependence on pallets and is usually used for certain special types of cargo transportation or small batch, high-value goods.

[0004] At present, many traditional cargo handling systems still rely on a lot of manual operations, especially in the process of loading, unloading, stacking and handling of cargo. Manual operations are not only inefficient, but also prone to errors and delays. Traditional loading and unloading systems rely on pallets as transportation units, which not only requires additional pallet management and storage, but also may bring the risk of pallet damage, loss or waste. Traditional loading and unloading systems usually have simple management of cargo stacking, resulting in low space utilization efficiency. Therefore, the present invention proposes an intelligent logistics loading and unloading system without pallet transportation to solve the problems mentioned in the above background technology. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an intelligent logistics loading and unloading system for pallet-free transportation.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An intelligent logistics loading and unloading system for pallet-free transportation comprises a storage frame, wherein a movable storage frame that slides up and down is arranged inside the storage frame, a lifting cylinder is arranged at the lower side of the movable storage frame, the lifting cylinder is installed at the lower part of the storage frame, and the output end of the lifting cylinder is rotatably connected with the lower side of the storage frame, a loading and unloading frame is arranged at the front side of the storage frame, a roller group 1 is installed at the upper side of the loading and unloading frame, and a roller group 2 corresponding to the roller group 1 is installed at the lower part of the movable storage frame;

[0008] A roller conveyor is provided on one side of the loading and unloading frame, the upper end of the roller conveyor is higher than the roller group 1, a push frame seat that slides left and right is provided on the upper side of the loading and unloading frame, the push frame seat is located on the upper side of the roller group 1, a propulsion cylinder is fixedly installed on the upper side of the loading and unloading frame, and the front end output shaft of the propulsion cylinder is fixedly connected to the front side of the push frame seat;

[0010] Preferably, a plurality of limit blocks are arranged on the left and right sides of the movable storage frame, and the limit blocks on the same side are arranged in sequence from top to bottom, and the spacing between the upper and lower adjacent limit blocks is the same, and the height of the pushing frame seat is less than or equal to the spacing between the upper and lower limit blocks.

[0011] Preferably, the height of the storage frame is greater than twice the height of the movable storage frame, and the distance from the upper side of the loading and unloading frame to the top of the storage frame is greater than or equal to the height of the movable storage frame.

[0012] Preferably, the length of the pushing frame seat is less than or equal to the length of roller group 2, and an opening corresponding to the upper end of the roller conveyor is provided on one side of the pushing frame seat.

[0013] Preferably, the left and right sides of the front side of the storage frame are rotatably connected with gear rollers, and the left and right sides of the front side of the movable storage frame are provided with tooth grooves for meshing with gear rollers.

[0014] Preferably, a corresponding spur gear is arranged on the outer side of the gear roller, and the two spur gears are rotatably connected to the left and right sides of the front side of the storage frame respectively.

[0015] Preferably, the front left and right sides of the loading and unloading frame are rotatably connected to rotating wheels, the outer sides of the rotating wheels are rotatably connected to a plurality of ratchet blocks, a torsion spring is provided at the ratchet block transition, and a tooth groove corresponding to the ratchet block is provided at the lower side of the front end of the straight bar.

Efficient and precise loading and unloading and stacking not only save time, but also improve the space utilization rate of storage and transportation;

[0019] 2. The present invention greatly reduces the dependence on pallets, and adopts a pallet-free method for transporting and stacking goods. Through a flexible movable storage frame and an automatic loading and unloading mechanism, the goods can be directly loaded, unloaded and stacked in the system, which not only saves the purchase and maintenance costs of pallets, but also simplifies the entire logistics process and reduces the demand for manpower. By promoting the coordinated work of components such as cylinders and roller groups, the fully automatic cargo transportation and stacking process is realized. Compared with traditional manual loading and unloading, the improvement of the degree of automation greatly reduces human errors and improves the accuracy and safety of operations;

[0020] 3. The present invention is equipped with a limit block and a push frame with adjustable height to adapt to goods of different sizes and shapes, and can efficiently handle various goods, whether small batches or large batches of goods. The design of the limit block ensures that the goods will not shift or tilt during the stacking process, maintain a stable stacking state, and improve the safety of the goods. The goods can be stacked and stored at different heights, which can save storage and transportation space to the maximum extent and adapt to logistics needs of different scales.

[0021] In summary, the intelligent logistics loading and unloading system for pallet-free transportation of the present invention greatly improves the efficiency, flexibility and safety of the logistics system through innovative design and highly automated control. Its advantages include efficient cargo loading and unloading and stacking, reduced pallet dependence, flexible cargo adaptability, automated control, space saving and cost reduction, etc. The system is suitable for various logistics scenarios, especially in modern warehousing and transportation environments, and has broad application prospects.
