Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rod stacking, in particular to an automatic aluminum alloy rod stacking and bundling device. BACKGROUND

[0002] Aluminum alloy rods are important industrial raw materials and are widely used in metallurgy, aerospace, automobile manufacturing and other fields. During their production, storage and transportation, multiple rods are usually stacked into a pile in layers and bundled with steel bands or plastic straps for easy lifting, handling and storage. Currently, the stacking and bundling of aluminum alloy rods still mostly rely on manual or semi-mechanical equipment. The traditional operation method has the following problems: a large amount of manual intervention is required for rod picking, transferring, aligning and stacking, resulting in high labor intensity and low production efficiency, which cannot meet the requirements of modern production lines for rhythm and capacity; during manual stacking, the layers of rods are not easy to align, resulting in unstable material piles that are prone to scatter and collapse during handling, which not only damages the surface quality of the rods, but also poses a threat to the personal safety of the operators; existing bundling equipment often has single functions and a complicated bundling process, especially when the strap is sleeved into a large material pile, which is difficult to operate and ensures that the strap is evenly and tightly bundled at both ends of the material pile, resulting in loose bundling during transportation; cylindrical rods are prone to roll off the side of the material pile after stacking, especially when tilted or subjected to vibration. There is a lack of a roll-preventing mechanism that can be automatically triggered during stacking and self-adaptively adjusted according to the stacking height of the rods, which further increases the instability and danger of the operation. In order to solve the above problems, there is an urgent need in the field for a fully automated device that integrates automatic stacking, precise alignment, reliable roll prevention and efficient bundling to achieve efficient, safe and stable aluminum alloy rod stacking and bundling operations.
