The invention discloses a method applied to correcting, pushing, rinsing, conveying, filling, cap transporting, cushion transporting, punching, extruding and cap screwing of filling bottles. The method is constructed based on a system applied to the correcting, pushing, rinsing, conveying, filling, cap transporting, cushion transporting, punching, extruding and cap screwing of the filling bottles. The system comprises a correcting device, a pushing device, a carrying device, a rinsing device, a propelling device, a conveying device, a filling device, a cap transporting device, a cushion transporting device and a punching and extruding device, wherein the correcting device is a cavity with an opening in one end; the inside wall of the cavity is provided with a material channel which rises spirally and upwards; the pushing device comprises a pushing air cylinder and a pushing platform. By virtue of the method, the problem of oriented transportation of the filling bottles can be solved; meanwhile, the problems of automatic rinsing, propelling, conveying, filling, cap transporting and sealing cushion transporting of the filling bottles can be solved; furthermore, the problems that sealing cushions are easy to fall off and caps are screwed when the bottle caps and the sealing cushions of the filling bottles are rotatably placed can be solved.
