- the first auto coupler 301 After assembling the alignment block 720 in the third high-pressure gas cylinder 203, when the operator lowers the first auto coupler 301 located at the top dead center, low-pressure compressed air is acting on the actuator 326. Since the first auto coupler 301 and the force balance are maintained, the first auto coupler 301 can be lowered with a small force.
- the first auto coupler 301 When the first auto coupler 301 descends, the operator visually identifies the position of the guide pin 711 and the alignment hole 711 of the alignment block 720 assembled on the upper portion of the third high pressure gas cylinder 203 If the position of the third high-pressure gas cylinder 203 is finely adjusted so that the guide pin 711 is inserted into ), when the first auto coupler 301 aligns the third high-pressure gas cylinder 203, the first auto coupler The central shaft 322 fixed to the 301 is coupled to the through hole 321a of the top plate 321 so that it can flow forward, backward, left and right, so that the guide pin 711 is accurately inserted into the alignment hole 721 As a result, alignment of the third high-pressure gas cylinder 203 is performed, and after the alignment of the third high-pressure gas cylinder 203 is completed, a ninth step of closing the door 110 is performed.
- the end cap holder 312, the connector holder 311, and the valve connector 230 are positioned on the horizontal line.
- the operator touches the screen 120, and the type of gas, which is the information of the new third high pressure gas cylinder 203, and a barcode After inputting the weight, etc., the door 110 of the cabinet 100 is closed and a button confirming that the replacement of the high-pressure gas cylinder is completed is touched.
- the proximity sensor (not shown) checks whether the docking of the first auto coupler 301 is correctly performed. If it is normal, the next step is performed, and if the alignment position is misaligned or abnormal, an error is generated to open the door 110 that was closed by the operator, take out the third high pressure gas cylinder 203, and then reinsert the door 110 and close the door 110 Will perform.
- the end cap 240 is separated from the third high-pressure gas cylinder 203 using the end cap holder 312 of the connection unit 310, and then a separate sensor ( Not shown) determines whether the end cap 240 is separated from the valve connector 230, and if the end cap 240 is separated, the valve connector 230 of the third high pressure gas cylinder 203 is connected to the connector holder 311 ) And the end cap 240 is not separated, an error occurs and the operator performs the tenth step of taking action.
- an emergency before opening the valve handle 220 of the third high pressure gas cylinder 203 It is more preferable to further perform an operation of winding the mainspring around the shaft (not shown) of the valve handle unit 400 so that the valve handle 220 is automatically closed in case of an emergency.
- valve handle holder 410 of the valve handle unit 400 After winding the mainspring (not shown) on the shaft of the valve handle unit 400 so that the valve handle 220 of the third high pressure gas cylinder 203 is closed, the valve handle holder 410 of the valve handle unit 400 is removed. The 11th step of waiting by opening the valve handle 220 of the third high-pressure gas cylinder 203 is performed.
- the high-pressure gas cylinder that has been supplied with gas is automatically replaced.
- 3-4 or more of the high-pressure gas cylinders 200 are built in the cabinet 100, and the same number of auto couplers 300 as those of the built-in high-pressure gas cylinders are installed to detect the replacement timing of the high-pressure gas cylinders 200 from the control unit. It is understandable that the high-pressure gas cylinder 200 may be sequentially replaced each time.

- valve connector 240 hand cap
- connector holder 311 connector holder 312: end cap holder
- actuator 400 valve handle unit
- valve handle holder 500 gasket automatic replacement means
