After the setting, the gripper 4 7 丨 moves only in the Y and Z directions during unloading, and does not move in the G and X directions to simplify control and minimize the unloading cycle time. The conveyor system 500 is used for unloading storage areas for forming bars, and the bars are unloaded and separated therefrom. The unloading system 5 00 locates itself only based on the bar information from the machine controller, and does not change its X direction during unloading. The conveyor system 5 0 0 ensures that the unloading system 4 0 will be empty at the location where P will be loaded. The slat conveyor belt 5 1 0 moves the rods in the X direction to ensure that all the rods on it do not include the feeding system 100, the bending system 2 00, the unloading system 4 0, and the conveyor system. The integrated system of 500 can have great profit in the bending operation of bars. The fully automatic setting operation can greatly reduce the operator's setting time, technical level, and human error \ Fully automated bending and unloading f ^ Conveying system, reducing human resources requirements to a single operation on the feeding system side!
