Abstract
A method and mobile filling station for filling of insulating glass (IG) units is designed to be simple, reliable, low in cost, flexible in operation, improving the productivity of filling process and decreasing the number of IG units destroyed during the filling process. The mobile filling station is built-up as a system of independent modules, each module being used for filling of an IG
unit. Each module includes a filling gas detector able to detect the presence of any filling gas used in IG units filling process, a control system of the filling process and a monitoring system of the main parameters of the filling process, being used for any filling gas and any number or dimensions of IG units to be filled-up independently and at the same time. To eliminate damages of the IG
units due to of a difference between the pressure of inner space of the IG unit and the atmospheric pressure, the inner pressure of the IG unit, during the filling process, is maintained equal to the atmospheric pressure or, if necessary, corrected to compensate the difference of the two pressures due to the altitudes of the future location of the IG unit. The mobile filling station has an ergonomic construction and like this the operational time and effort are reduced. Since the entire process is fully automatic no trained personnel is needed. The insulated glass units are not manipulated during the filling process. The modules to control the filling process are concentrated in a mobile filling station

Description
SPECIFICATION
The present invention relates to a method and mobile filling station for the IG units filling process, bein~ adaptable to any dimension and number of IG units and any fillin~ ~as.
The difficulties to develop activities related to the fillin~ process of IG units are well known. Often the activities related to such a process involve expensive equipmclll, well trained ope~ ~lol ~, risk to destroy IG units, difficult and costly h~n~ling of IG units, the result bein~ a high cost of the IG unit, a .~ b~ ial air content ofthe inner space of the IG unit, a low productivity of the filling proce~s and major filling gas waste.
The prior art teaches basically two methods of IG units filling: lance filling and chamber fillin~. Lance filling is ba~ed on crealing two holes in the frame ofthe IG unit, one to evacuate the air and the other to introduce the filling gas, some methods involves only one hole to evacuate the gas and to introduce the air.
The cha,l.ber filling method consist~ in using a vacuum chamber to place the open IG units. The air is pumped out from the chamber, replaced with fillinR
gas and then the IG units are sealed. Prior art lance filling methods are unproductive, c.l.llbel ~ome, time colA--..il~e have a low accuracy in establishin~ the moment when the IG unit is filled-up and involve ehyensi~fe e~lll;plnelll.
