Description

Technical Field

[0001] This invention relates to the field of loading, unloading, or transshipment technology for boxed or bagged goods, and is particularly applicable to the loading and unloading process of imported and exported boxed or bagged cold chain fresh produce. It also relates to a continuous loading and unloading device for boxed or bagged goods. Background Technology

[0002] Domestically, the import and export of mainstream cold chain fresh produce lacks dedicated terminals and specialized equipment for loading and unloading operations. The main methods rely on the ship's own cranes or gantry cranes used for general cargo handling on shore. When unloading is required, manual labor is used to palletize or pack goods inside the ship's hold, followed by crane loading and unloading from the hold onto the shore. The goods are then unpacked and loaded onto trucks or transported to warehouses.

[0003] This operating method has several shortcomings: First, it is inefficient. The loading and unloading process from unloading to warehousing involves frequent manual palletizing or packing, and manual depalletizing or unpacking. Furthermore, crane operation is not a continuous conveying process, resulting in long idle times and low overall efficiency. Second, with the rapid development of the cold chain logistics industry, the demand for continuous, efficient, and intelligent loading and unloading operations for cold chain fresh produce is increasing. Customers expect goods to be manually depalletized from the ship's hold and then unloaded by specialized machinery, and then directly transported to the shore-based cold storage for further palletizing and stacking via a conveyor line, reducing intermediate palletizing and depalletizing steps and saving manpower. Therefore, a new continuous loading and unloading device is needed. Summary of the Invention

[0004] In response to the aforementioned technical problems, a continuous loading and unloading device for boxed or bagged goods is provided.

[0068] Working principle: Goods are manually placed on the head receiving machine 4, and the receiving belt conveyor 4-1 transports the goods forward to the delivery position. The vertical elevator 5's elevator drive sprocket 5-3 rotates, causing the elevator roller chain 5-4 to circulate. When the elevator bracket 5-5, fixed at regular intervals, passes through the delivery position of the head receiving machine 4, the goods are automatically transferred to the elevator bracket 5-5, and then lifted to the top of the elevator drive sprocket 5-3. When the elevator bracket 5-5 passes through the intermediate receiving machine 7, the goods are automatically transferred to the intermediate receiving machine guide frame 7-2, and then slide freely down to the intermediate belt conveyor 7-1. The intermediate belt conveyor 7-1 transports the goods forward to the delivery position. The rotation of the conveyor drive sprocket 8-3 of the intermediate conveyor 8 drives the conveyor roller chain 8-5 to rotate cyclically. When the conveyor bracket 8-6, which is fixed at a fixed distance, passes through the delivery position of the intermediate receiving machine 7, the goods are automatically transferred to the conveyor bracket 8-6. Subsequently, the goods are transported to the end of the conveyor driven sprocket 8-4. When the conveyor bracket 8-6 passes through the ground receiving machine guide frame 9-1 of the ground receiving machine 9, the goods are automatically transferred to the ground receiving machine 9 and slide freely down to the ground delivery position. Finally, the goods are manually removed. This continuous process completes the loading and unloading operation.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
