Description

Technical Field

[0001] This invention belongs to the field of industrial automation technology, and particularly relates to the field of filling technology, specifically to an automatic loading and unloading system for ton bag filling. Background Technology

[0002] Ton bags, as a common large-capacity packaging container, are widely used for the transportation and storage of bulk materials in industries such as chemicals, grains, building materials, and mining. Currently, the filling and loading / unloading operations of ton bags generally suffer from the following problems: Low level of automation: Most companies still use manual operation of cranes, such as electric hoists, to complete the lifting, hanging, filling and unloading of ton bags. Manual bag hanging has poor alignment accuracy, low efficiency and poses a great safety hazard.

[0003] Severe dust pollution: During the filling and unloading process, the mixture of materials and air easily generates a large amount of dust, which not only causes material loss, but also seriously pollutes the working environment, endangers the health of operators, and does not meet environmental protection requirements.

[0004] High labor intensity and high labor costs: The entire process requires manual participation, including bag hanging, assisted alignment, opening the unloading port, etc., which is labor-intensive and highly dependent on the number of operators.

[0005] Poor system integration: Filling, conveying, and unloading processes are often independent, lacking a unified control system for scheduling and management, resulting in disjointed logistics and affecting overall production efficiency. Summary of the Invention
