Definitions
- the invention relates to a method for filling the interior of insulating glass sheet blanks consisting of at least two Glass panes and a spacer frame arranged between them exist with a gas other than air, in particular with argon, with a slit-shaped opening for the Supply of gas and extraction of air or air-gas mixture is formed by one of the glass panes of the insulating glass blank with elastic bending of this glass pane is kept at a distance from the spacer frame if the insulating glass blank after assembling the Disc packs in a press between press plates essentially is pressed vertically, whereby by the so formed, gap-shaped opening in the interior of the insulating glass blank Blown in gas and air or air-gas mixture from the interior of the insulating glass blank is subtracted (WO 89/11021).
- Such filling gases are e.g. Argon or a so-called heavy gas, such as sulfur hexafluoride.
- WO 89/11021 It is also known (WO 89/11021), an opening for gas exchange in an insulating glass blank between the spacer frame and one of the glass panes of the insulating glass blank to form that, for example, in Area of a side edge of the insulating glass blank a glass sheet from multiple suction heads to form one The curvature in the glass pane is lifted off the spacer frame becomes.
- WO 89/11021 also proposes the one Bend the glass pane away from the spacer frame at two corners and so two diagonally opposite openings form.
- the procedure known from WO 89/11021 is disadvantageous in that it extends in several directions Curvature arises, increasing the risk of breakage lifted glass pane is created. Also take off the glass pane from the spacer frame along one High forces are required on the side edge or in the area of two corners.
- the invention has for its object that from WO 89/11021 to improve known methods in such a way that not only the actual exchange of gas is quick and easy but that the manufacture and subsequent sealing of holes in the spacer frame is avoided without the disadvantages of the methods described above, in which gas exchange through a gap in the area of the lower horizontal Leg of the spacer frame occurs.
- this object is achieved in that a the glass panes of the insulating glass blank in the area only a lower corner of the insulating glass blank in the Distance from the spacer frame is held during the remaining part of this glass pane through the press plates in plant is held on the spacer frame that gas by means of a probe with an im substantially parallel to the lower horizontal leg of the Spacer frame aligned flow direction in the Interior of the insulating glass sheet blank is blown and that by means of a probe air or air-gas mixture through an area the slit-shaped Opening from the interior of the insulating glass blank is subtracted above the range of gap-shaped opening lies through the gas into the interior of the insulating glass blank is blown.
- the gas exchange is particularly quick and easy, if so the procedure is followed by a gas feed probe essentially parallel to the lower, horizontal leg of the spacer frame aligned gas flow into the interior of the insulating glass blank is blown.
- a gas feed probe essentially parallel to the lower, horizontal leg of the spacer frame aligned gas flow into the interior of the insulating glass blank is blown.
- a mixing of the supplied gas largely with the outflowing air or air-gas mixture prevents because the gas, which is the air inside the window should replace, in a broad front from that of the filling point opposite side to the filling side moves while the air-gas mixture or the air gradually presses under compression towards the suction probe.
- one for withdrawing air or air-gas mixture a probe is used to feed above the probe of gas is arranged and the one obliquely upwards directed and pioneering by the gas delivery probe Mouth for withdrawing air or air-gas mixture from the Has interior of the insulating glass blank.
- the gas delivery probe Mouth for withdrawing air or air-gas mixture from the Has interior of the insulating glass blank.
- the a gas introduced through the probe e.g. argon
- the probes do not pass through in the method according to the invention Holes, but through the open area in the corner in the Interior of the insulating glass blank are introduced, can this also in the inventive method if the Probes in different directions, e.g. point away from each other, at the same time in the interior of the insulating glass pane be introduced.
- the amount of gas in the invention Procedure used can be done simply by doing so be determined that the gas exchange continues until I'm over the one probe aspirated air-gas mixture the proportion of air falls below a predetermined value.
- a device to carry out of the method according to the invention in particular has two press plates that for pressing the essentially vertically standing insulating glass blank each other can be approximated, a probe for introduction of gas in the space between the glass panes of the insulating glass blank and a probe for extracting air or air-gas mixture from the interior of the insulating glass blank, being on one of the press plates a suction device is provided with which is one of the glass panes of the insulating glass blank at a distance from the spacer frame is held by being under elastic Deformation bent away from the spacer frame becomes.
- the suction device is in the range lower corner of one of the plates of the press provided the area of the press plate, in which the suction device is provided with the remaining part of the press plate can be pivoted connected is.
- the press e.g. one of the design known from DE-PS 31 30 645
- the disc package is pressed and the cover disc in a lower corner 2 of the disc pact, preferably the front, lower corner at a distance from the spacer frame held and / or lifted off the spacer frame or kept at a distance from the spacer frame.
- mounted probe 5 has a mouth which is directed obliquely upwards and serves for vacuuming from the interior of the insulating glass blank displaced air or air-gas mixture.
- the gas exchange is carried out so that in the interior of the Insulating glass blank always at least a small one Overpressure prevails, so that gas is continuously exchanged and possibly excess air or gas-air mixture what is not displaced from the interior bothers because the fill gas, especially if it is argon is not expensive.
- the gas filling is controlled either by measuring of the residual oxygen content in the interior of the Insulated glass pane blank drawn off gas-air mixture, by determining the composition of the air-gas mixture in the interior of the insulating glass blank and / or by determining (calculating) the volume of the Interior of the pane and supply of a correspondingly metered amount Amount of gas, with some loss due to prevailing overpressure is taken into account in that the calculated volume by e.g. empirically specified fraction is increased.
- Advantages of the method according to the invention are that you can work continuously and not constantly be changed between blowing and suction got to. Also eliminated in the procedure according to the invention drilling and subsequent closing of openings in the spacer frame through which the probes are to be introduced. Another advantage is that the mixing between supplied gas and air in Interior of insulating glass blank in limits is kept, since such mixing is only limited Extent occurs.
- a press shown schematically in FIG. 4 has two press plates 10 and 11 which are movable relative to each other are like this for presses for pressing insulating glass blanks is known per se.
- a pressure medium cylinder 15 is provided, on the one hand 16 with the press plate 11 and on the other hand via one of the corner area 12 projecting shoulder 17 connected to this is.
- actuating the pressure medium cylinder 15 can the corner region 12 in the direction of the double arrow 18th (Fig. 4) are pivoted back and forth.
- the press is opened by pressing plate 11 is moved away from the press plate 10 and so with gas, for example argon, filled insulating glass blank 1 funded from the press and, for example, a sealing station fed.
- gas for example argon
