Claim 0:
1. An automatic alignment method of a high-pressure gas container, comprising in sequence the steps of:
loading a high-pressure gas container on a lift and raising the lift until a first sensor detects an upper end of a valve handle installed on the upper portion of the high-pressure gas container;
re-driving the lift so as to re-raise the high-pressure gas container by a value set in a control unit (distance to the center of an end cap from the upper end of the valve handle) and then stopping the operation of the lift;
rotating the high-pressure gas container and, when a second sensor senses a start point of the end cap, notifying the control unit;
continuously rotating the high-pressure gas container and, when the second sensor senses an end point of the end cap, notifying the control unit simultaneously with stopping the rotation of the high-pressure gas container, and rotating the high-pressure gas container in the opposite direction according to the θ-center of the end cap, which is calculated by the control unit, so as to align the θ-center of the end cap with the center of the second sensor;
raising the lift and, when the second sensor senses the top dead center of the end cap, notifying the control unit and stopping the raising of the lift; and
lowering the lift and, when the second sensor senses the bottom dead center of the end cap, notifying the control unit simultaneously with stopping the lowering of the lift, and raising the lift according to the Z-center of the end cap, which is calculated by the control unit, so as to align the Z-center of the end cap with the center of the second sensor.
