Thereafter, the plug 430 fastened to the gas connector 230 is separated from the gas connector 230 as the grand nut 240 rotates in a state where the movable plate 220 is no load, A standby state is avoided by the plug unit movable part 420 and the plug pivot arm 440 to one side of the gas connector 230 .

In addition, the end cap C3 is separated from the gas outlet port C2 by the end cap unit 300 , and the end cap C3 waits while being held by the end cap holder 330 . .

Then, the gas outlet port C2 is connected to the gas connector 230 by the connector unit 200, and the valve C1 is released by the valve unit 600 to fill the gas cylinder C. The gas is supplied to gas demanders.

On the other hand, when the supply of gas to the gas demander is completed as described above, after the valve C1 is closed by the valve unit 600 , the gas connector 230 and the gas outlet are connected by the connector unit 200 . The ports C2 are spaced apart, and the used gasket G is discharged to the gasket collection box 580 by the gas gripper 530 .

In addition, the plug 430 is fastened to the gas connector 230 , and the end cap C3 , which has been waiting while being held by the end cap holder 330 , is fastened to the gas outlet port C2 .
