When all the gas stored in the currently connected container is consumed, the control unit transfers the connecting pipe connector 331 through the connecting pipe connector transfer system 340, 335 to remove it from the valve of the currently connected container. The connector is separated, and then the waste gasket installed on the connector 331 of the connecting part is transferred by the gasket holder transfer mechanism 383, 384 to be recovered to the gasket recovery part 390, and then transferred by the plug Mechanisms 364 , 365 move the connector plug 361 and couple it to the connecting pipe connector 331 .

Thereafter, if the current container is replaced with a new container, the control unit moves the connector plug 361 by the plug transfer mechanism 364, 365 to separate from the connection pipe connector 331, and then passes the The gasket storage section transfer mechanism 373 transfers the new gasket stored in the gasket storage section 372 to be attached to the connection pipe connector 331, and then transfers the connection pipe by the connection pipe connector transfer system 340, 335. Connector 331 and couple it to the valve connector of the new container after replacement.

That is, the container replacement process using the connector plug 361 according to the present invention is compared with the prior art by omitting installation and separation for the connection before and after coupling the connector plug 361 and the connecting pipe connector 331. The process of sealing the gasket between the connector plug and the connecting tubing connector, thereby shortening the gasket replacement process, which in turn simplifies the container replacement process.

As described above, with the connector plug 361 and the gas supply device 1 including the connector plug 361 according to the present invention, not only the container replacement process can be simplified to save time required, but also the automation process required for the container replacement process can be saved. of electricity and save on the charges imposed on the use of electricity.

In addition, by shortening the replacement process of the gasket 371a, shortening the replacement time and minimizing the time the connecting pipe is exposed to the outside, gas leakage from the connecting pipe or foreign matter entering the connecting pipe can be prevented.

Also, the consumption of the gasket 371a can be reduced, thereby reducing the cost required for the container replacement process and improving economical efficiency.

As mentioned above, although the present invention has been described in detail by taking the preferred embodiment as an example, the present invention is not limited to the foregoing embodiment, and various modifications can be made within the scope of the claims, the detailed description of the invention, and the accompanying drawings. implementation, and these also belong to the present invention.
