Raw material conveying line system and operation method thereof

The invention discloses a raw material conveying line system which comprises a main rail. A pair of floor lifting machines is arranged in the middle of one side of the main rail. A main roller transfer machine is arranged between each floor lifting machine and the main rail. A main RGV is arranged at the position, corresponding to each floor lifting machine, of the main rail. A plurality of branch rails which are perpendicular to the main rail and independent from one another and do not intersect with one another are arranged on the other side of the main rail side by side. A branch roller transfer machine is arranged between each branch rail and the main rail, and each branch rail is provided with a branch RGV. A plurality of material bins are distributed on the two sides of each branch rail. An electric block is arranged between each material bin and the corresponding branch rail. Each branch rail is provided with a code disc. System resources are reasonably configured, the working gap periods of all system
