The invention provides an unloading method for reducing coil unloading auxiliary time, which comprises the following steps of: S1, starting coil unloading operation when the speed of a strip in an outlet area is reduced to be below a threshold speed; s2, the strip (1) is clamped by a pinch roll (3) in a pressed-down state, and the conveying speed of the strip is reduced to zero; s3, strip unloading operation is executed in an outlet area, a crop shear (4) is pressed down, and a strip head which reaches the crop shear (4) through a deflector roller (2) of the strip starting station is sheared; the coiling machine (7) is used for coiling the strip sheared by the crop shear into a coiled material by using a reel; s4, in the coiling process of the coiling machine, a follow-up device motor (6) of the starting station drives the rack where the deflector roller is located to retreat, meanwhile, the coil stripping trolley moves to the position below a coiling shaft of the coiling machine to the coiling and coil strip
