[0024] Working process:

[0025] ① Feeding and conveying: The profiled steel stack 110 is placed on the horizontal chain bed 120 and intermittently transported forward. When the profiled steel stack 110 reaches above the swing chain bed 130, the horizontal chain bed 120 stops moving, and the swing chain bed 130 continues to transport the profiled steel stack 110 backward. When the profiled steel stack 110 reaches directly above the stack conveying roller path 140, the swing chain of the swing chain bed 130 swings downward around the rotation axis, and the profiled steel stack 110 is placed on the stack conveying roller path 140. The stack conveying roller path is driven by a motor reducer to send the profiled steel stack 110 to the subsequent unpacking station and is blocked by a baffle to ensure accurate stopping position.

[0026] ② Unpacking of the profiled steel stack: The electromagnetic device, driven by the unpacking robot 210, extracts the layers of the profiled steel stack 110, and the single-layer profiled steels 220 after being split layer by layer are placed on the multi-section chain bed 230 of the present invention and transported forward.

[0027] ③Grouping and spacing: The working process of the section steel grouping: First, turn the baffle 253 to the vertical state; the single-layer section steel 220 runs forward driven by the multi-section chain bed 230 and is blocked by the turned baffle 253; when the number of the blocked section steel reaches the requirement, the lifting frame 241 rises driven by the driving cylinder 242, and the part of the section steel 221 after grouping is lifted to be separated from the multi-section chain bed 230; then the turned baffle 253 tilts to discharge the material, and the grouped section steel group 222 is driven by the multi-section chain bed 230 to leave the grouping area and be conveyed to the subsequent process; after the section steel group 222 leaves, the baffle 253 is erected again, and the lifting frame 241 descends to perform the next grouping operation; when the number of section steel in the section steel group 222 needs to be adjusted according to the production process, the baffle 253 is horizontally adjusted by a certain distance driven by the driving electric cylinder 252 to meet the requirement of the change in the number of the section steel group 222; The process of spacing the section steel is as follows: Each top block 264 lifts a section steel in the section steel group 222, and the cam plug 263 moves horizontally on the slide rail 262 driven by the driving device, forcing the top block 264 to move along the linear slideway 265 and the radial slideway 266, so as to change the distance between the section steel, and thus complete the change in the distance between each section steel in the section steel group 222 to become the variable-spacing section steel 223;

[0028] ④Feeding and transporting the variable-spacing section steel: The initial position of the feeding trolley 310 is below the variable-spacing device 260 in the multi-section chain bed 230. When the variable-spacing operation is completed, the variable-spacing section steel 223 is lifted and placed on the single-layer roller conveyor line 320 to transport the variable-spacing section steel 223 to the subsequent process.
