The loading and unloading method of the loading and unloading mechanism of the winder according to claim 7, characterized in that: The following steps are involved: 1) manually placing the workpiece (1) on the discharge trough (5), rolling the workpiece (1) along the discharge trough (5) to one end of the discharge trough (5), then opening the loading block (9), and the workpiece (1) falling onto the feeding table (15); 2) The feeding table (15) drives the workpiece (1) to move to a position above the lifting device (c), so that the workpiece (1) is placed on the air shaft (2), and the air shaft (2) is inflated and tightens the workpiece (1); 3) The lifting movable frame (19) drives the turning table (20) to rise, so that the turning table (20) can bear the workpiece (1), the clamping assembly (26) releases the air shaft (2), the movable vehicle (24) drives the clamping assembly (26) to retreat, and then the lifting movable frame (19) drives the turning table (20) to descend a certain distance, so that the air shaft (2) with the workpiece (1) is placed on the material receiving table (3); 4) The turning arm (31) turns upward and supports the air-expanding shaft (2) on the material receiving platform (3) with the workpiece (1) and moves it to the winding mechanism (A). The manipulator device clamps the workpiece (1) and moves it to the winding device (h) to wind the workpiece (1). After the workpiece (1) is wound, the winding device (h) moves the workpiece (1) to the conveying device (i), and the conveying device (i) conveys the workpiece (1) to the turning arm (31); 5) The turning arm (31) turns downward and supports the air shaft (2) with the workpiece (1) and moves it to the material receiving platform (3), and then the lifting movable frame (19) drives the turning platform (20) to rise, so that the turning platform (20) supports the workpiece (1) and drives the workpiece (1) to move upward, the movable vehicle (24) drives the clamping assembly (26) forward, the clamping assembly (26) clamps the air shaft (2), and the air shaft (2) deflates to release the workpiece (1), and then the movable vehicle (24) drives the clamping assembly (26) and the air shaft (2) backward to separate the workpiece (1) from the air shaft (2); 6) The lifting movable frame (19) drives the turning table (20) to descend a certain distance, and then the turning table (20) turns over, so that the workpiece (1) falls along the turning table (20) onto the unloading rack (34), and the workpiece (1) slides along the unloading rack (34) onto the conveying roller assembly (35). The conveying roller assembly (35) conveys the workpiece (1) to the unloading roller assembly (37), and the unloading roller assembly (37) conveys the workpiece (1) to the unloading vehicle.
