Meanwhile, referring to FIG. 11 , the alignment housing unit 700 rotates in the x-axis with respect to the alignment housing base 710 fixedly installed on the lower surface of the valve unit 600 and the alignment housing base 710. , includes a slider 720 that moves backward.

More specifically, a locking handle 711 is formed on one side of the align housing base 710, and when the locking handle 711 is rotated, it is fastened between the align housing base 710 and the slider 720. As the plurality of connecting "D" points 712 rotate, the distance between the align housing base 710 and the slider 720 is adjusted.

In addition, a hole is formed on the bottom surface of the align housing base 710 and the slider 720 so that the head side of the gas cylinder (C) can be inserted, and the valve C1 is formed on the upper surface of the valve shutter ( 610), and holes are formed to expose the gas outlet port C2 and the end cap C3 to the base main frame 110 side.

More preferably, when the gas cylinder (C) is fastened to the align housing unit 700, the valve (C1) is inserted into the valve shutter 610 side, and the gas outlet port (C2) and the end cap ( C3) is formed to be exposed toward the connector unit 200 side.

Meanwhile, the operation method of the automatic gas supply device including the gasket unit for the automatic gas supply device according to the present invention configured as described above is as follows.

First, the operator inserts the gas cylinder (C), the valve (C1) into the valve shutter (610) side, and the gas outlet port (C2) and the end cap (C3) face the connector unit (200). It is fastened to the in-housing unit 700.

At this time, the position alignment of the align housing unit 700 and the gas cylinder (C) is performed with respect to the third plate 140 by the third plate 140 and the floating bolt 143 coupled to a hoist or the like. This can be achieved by the second plate 130 capable of rotation or fine alignment.

Thereafter, the plug 430 fastened to the gas connector 230 is separated from the gas connector 230 as the ground nut 240 rotates in a state in which the movable plate 220 is unloaded, It stands by in a state of being avoided to one side of the gas connector 230 by the plug unit movable part 420 and the plug swing arm 440 .

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 stands by while being held by the end cap holder 330. .

Thereafter, 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 charge the gas cylinder C. The gas is supplied to the gas demander.

On the other hand, as described above, when gas supply to the gas consumer is completed, 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 port C2 is spaced apart and the previously 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 waiting while held by the end cap holder 330 is fastened to the gas outlet port C2.

Thereafter, the work is completed when the operator separates the gas cylinder (C) from the align housing unit (700).

As described above, the present invention has been described with reference to the drawings illustrated, but the present invention is not limited by the embodiments and drawings disclosed in this specification, and various modifications are made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that variations can be made.

In addition, although the operational effects according to the configuration of the present invention have not been explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the corresponding configuration should also be recognized.
