Description

[0002] At present, the storage process of the straightened reinforcing bar mainly relies on the transmission belt cooperating with the mechanical baffle for rough positioning, and the reinforcing bar is forced to be pushed into the storage area by the one-way push rod.

The mechanical baffle can only achieve the preliminary alignment of the end of the reinforcing bar, and cannot control the lateral deviation of the reinforcing bar during pushing into the storage area. The one-way push rod action will cause the collision and sliding of the reinforcing bars, generate the cumulative error of the micro-motion, and lead to the mispositioning and crossing of the reinforcing bars in the storage area. The fixed limiting groove cannot adapt to the storage requirements of reinforcing bars of different diameters, and cannot dynamically correct the existing pose deviation. SUMMARY
