Gas tank plastic packaging device {VINYL PACKAGING APPARATUS FOR GAS TANK}

The present invention relates to a gas tank vinyl packaging device, and more particularly, an energy-independent type that can quickly move to the location of a gas tank to perform a vinyl shrink wrapping operation, and also applies vinyl to the surface of the gas tank in the first and second steps. It is possible to form a uniform shrink surface of vinyl by heat-shrinking separately, as well as shortening the shrinking time of vinyl by supplying hot air to pre-heat the vinyl before packaging by heat-shrinking the vinyl in the first and second stages on the surface of the gas tank. It relates to a gas tank plastic packaging device that enables

In general, special gases such as N2, N2O, NF3, NH3, Cl2, B2H6, and DCS, which are used in the semiconductor manufacturing field, are stored inside the gas tank in a liquid state (liquefied gas state) at room temperature.

Gas tanks in which these special gases are stored are usually supplied wrapped in vinyl to keep them clean.

In this packaging process, after covering the vinyl, heat is applied to the vinyl to shrink the vinyl while the vinyl adheres to the outer wall of the special gas cylinder. As the irregular contraction occurred, there was a problem in that an air layer was formed inside the vinyl.

In addition, since the work of covering a general special gas cylinder with vinyl and applying heat to the vinyl is performed by a worker's manual work, it is difficult to reduce the time and cost required to wrap the special gas cylinder.

In view of these problems, "Vinyl shrinking device for packaging special gas cylinders for semiconductor manufacturing: Korean Patent Registration No. 10-1559989_hereinafter referred to as cited literature) has been proposed.

However, since these cited documents shrink vinyl only by the heating unit, there is a problem in that non-uniform shrinkage surfaces occur during vinyl shrinkage.

In addition, the cited literature has to place the heavy special gas cylinder on the upper part of the base frame, so there is a risk of overturning when the special gas cylinder is seated.

Therefore, it is urgent to develop a device capable of eliminating the risk of the special gas cylinder being overturned and achieving a smooth shrinking surface of vinyl.

It relates to a gas tank vinyl wrapping device 100 that heat-shrinks in each secondary step to form a uniform shrink surface of vinyl.

The gas tank plastic packaging apparatus 100 according to the first embodiment of the present invention is largely composed of four parts, which include a supporting frame 10, a main frame 20, a lifting plate 40, and a heating drum 50 ) is composed of

The support frame 10 may be configured to be equipped with casters 11 so as to be movable to the position of the gas tank 200 .

These support frames 10 are composed of a pair, and the space between them is configured so that two support frames can be entered by movement with a gas tank interposed therebetween.

Between each of the support frames 10, a docking plate 12 docked with the gas tank 200 and positioning the heating drum 50 on a vertical line of the gas tank 200 is further coupled to quickly perform the plastic shrink-wrapping operation. configured to perform.

In addition, a handle frame 13 is further coupled to both sides of the support frame 10, and the handle frame 13 can serve as an additional function of preventing safety accidents when the gas tank 200 is overturned.

In addition, the support frame 10 is equipped with a power supply unit 14 with a built-in secondary battery to achieve energy independence and to provide a structure that can quickly perform vinyl shrink wrapping work regardless of location.

The main frame 20 is for supporting the heating drum 50 when it is raised and lowered, and is fixed to the supporting frame 10 in an upright state and has a structure in which a pair of rail frames 21 are fixed and supported.

The heating drum 50 is fixed to the elevating plate 40 and lifts, and functions to heat-shrink and wrap the vinyl 210 exterior to the gas tank 200 .

The heating drum 50 is for heating the circumference of the gas tank 200 to shrink vinyl, and is composed of a jacket 51 made of stainless and a ceramic heating element 52 embedded in the jacket 51. .

At this time, a heat wire (not shown) may be built into the ceramic heating body 52 so that heat can be transferred to the entire ceramic heating body 52 .

That is, while the heating drum 50 descends while covering the gas tank 200, the vinyl 210 sheathed on the gas tank 200 is shrunk by the radiant heat of the ceramic heating element 52 so as to be wrapped.

At this time, the lower inner diameter of the heating drum 50 is relatively larger than the upper inner diameter so that the vinyl exterior to the gas tank 200 is first contracted and then the second contracted in stages so that the vinyl does not lift the gas tank ( 200) to function on the surface.

That is, after the expanded inner diameter of the heating drum 50 primarily shrinks the vinyl 210, the upper inner diameter portion relatively close to the vinyl 210 secondarily contracts the vinyl 210, Compared to the heating drum 50 having a single inner diameter, a structure capable of forming a uniform shrinkage surface of vinyl may be provided.

In addition, since the gas tank 200 proceeds from the top to the bottom, air between the vinyl 210 and the gas tank 200 escapes to the lower part of the gas tank 200, so that an air layer is formed inside the vinyl 210. formation can be prevented.
