Description

Technical Field

[0001] The present invention relates to the technical field of mechanical sorting, and in particular to a steel bar sorting device. Background Art

[0002] Rebar processing in the construction industry is one of the important links in building construction. Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Initially purchased in bundles, the steel bars are relatively long. After purchasing the bundles, the steel bar processing companies need to cut them into lengths that meet actual usage requirements. After cutting, the steel bars of different lengths need to be sorted and classified, and then the individual steel bars need to be processed one by one. Due to the large number of steel bars used in the construction industry, the sorting of steel bars has brought certain difficulties, which is not conducive to the stable feeding of the steel bar cutting process. Existing steel bar sorting mechanisms usually use two methods for sorting. The first method uses vibration sorting, which has high requirements for the weight and texture of the steel bars themselves. There is also great friction between the ribbed steel bars, resulting in high false detection and missed detection rates. The second method uses single-bar measurement for sorting. Single-bar measurement is inefficient and cannot achieve batch sorting. It is labor-intensive and seriously affects construction efficiency. Therefore, it is urgent to design an automatic sorting device that can realize batch sorting functions and a high accuracy rate of steel bar sorting. Summary of the Invention
