FIELD OF THE INVENTION
The present invention relates to a system and a method for insertion of the one or more o-rings, and more specifically, the present invention relates to an automated system and the method for insertion of the one or more o-rings into the gas cylinder valve.

BACKGROUND OF THE INVENTION
With the increase in population, demand for food also increases.The use of solid fuels like coal, wood or charcoal creates pollution and hazardous in nature. The demand for liquefied petroleum gas is increases for cooking in many countries for economic reasons, and also it is environment friendly fuel. The liquefied petroleum gas is supplied in cylinders known as the gas cylinders or the liquefied petroleum gas cylinder. In order to maintain the seal in the valve of the gas cylinders, variety of components are used which prevent the leakage of the liquefied petroleum gas. The most commonly used component is the o-ring. The o-ring is placed in the valve of the cylinder. The o-ring provides a leakage proof seal. The o-ring gets loose or gets damaged with time. This increases the chances of gas leakage. To avoid this situation the o-ring is replaced. There are inherent challenges faced by replacing of o-ring manually which is very time consuming, costly and can damage or scratch the cylinder. As the whole process is manual, there are chances of leakage of gas in the cylinder. It is also possible to missing of replacing o-ring manually. To solve such problems, automatic method for insertion of an o-ring into a gas cylinder is introduced. So, by implementing automation, possibility of missing is ruled out.

US3947942A discloses a tool for O-ring seal for installation in an LP gas cylinder valve with a method and tool for installing the seal in the valve. The LP gas valve includes an outlet passage opening into a chamber within the main body of the valve which in turn is connected to a passage which opens into a cylinder tank. The outlet passage threadedly receives a hollow cylinder through which a stem projects. The stem includes an enlarged bullet shaped end projecting through an annular seat within the outlet passage and into a tapered portion of the outlet passage. An O-ring seal is installed on the annular seat effecting a seal between the valve and stem while spacing the enlarged bullet shaped end of the stem from the tapered portion of the outlet passage. A plate wrench has a hexagonally shaped hole through which a hexagonally shaped nut on the hollow cylinder projects. The wrench is used to tighten the stem with respect to the O-ring seal. Means are provided on the plate wrench for storing spare O-ring seals.

US8925756B2 discloses a tool for inserting of o-ring from gasket for a compressed gas cylinder arranged to operate with a gas cylinder having a neck with a top surface around a gas outlet and a side surface extending downwardly from the top surface. The gasket may include an upper portion arranged for positioning on the top surface of the cylinder and for making a seal with the top surface, and a lower portion extending downwardly from the upper portion and around the side surface of the neck of the cylinder, such that the lower portion is arranged to make a seal with the side surface of the gas cylinder. Face and gland seals may be established by the gasket with an opening that receives the gasket and an associated cylinder neck.

The present invention is an advancement of already existing systems in this field of invention. The drawbacks of already existing systems are that all the already existing systems are manual, which is very time consuming, costly and can damage or scratch the cylinder. The invention also involves less movable parts causes less friction and restored more energy. The existing invention used for insertion of the one or more o-rings can cause leakage of the gas. None of the existing technology uses such system and method that is disclosed in the present invention. The present invention effectively overcomes the deficiencies in the prior art. Hence there is a need for the present invention.
