Definitions
- the invention relates to a method for filling a space between two glasses of a disc-shaped Insulating glass unit with one between the The primary seals are arranged in glasses Spacer frame, with filling gas in a press for sealing together of the two glasses, after the Preamble of claim 1 and a device according to the Preamble of claim 7.
- the most common insulating glass units consist essentially of two opposing through a spacer frame made up of strips spaced glasses, the so produced Space is filled with a gas. To fill this the gas-tight space becomes pure, for example Argon, krypton or sulfur hexafluoride are used to make the To reduce the thermal conductivity of the insulating glass unit.
- DE-GM 87 15 749 describes a device for filling an insulating glass unit with filling gas known, the To avoid disadvantage of the risk of bursting of the glasses. Therefor two press cheeks are provided, which during the Filling process with preselectable pressure against the outer surfaces the glasses can be put on.
- the filling gas By so between slit-shaped emerging at the upper glass edges Gap viewed from the side approximate has a wedge-shaped profile, the filling gas, as it were filling a liquid into a container by means of a probe inserted into the space from above.
- the air to be displaced is measured using a probe suctioned off on the wedge-shaped side of the slit-shaped gap.
- the gas is supplied from above and sinking downwards must displace the air, which is inevitably the most penetrating Gas has to flow upwards so that it Edge can escape through the wedge-shaped gap this method is also unsatisfactory
- the gap can be filled. In particular remains Air in the two lower corners of the insulating glass unit back.
- the gas loss during filling is due to Leaks high and can be up to 200%, so that especially with expensive gases such as Krypton incur high loss costs.
- the invention is based on DE-OS 40 22 185.
- the object of the present invention is a method to provide with which the speed be further increased when filling the intermediate space can accept increased gas losses without this to have to.
- the spacer frame and the press side Sealant formed space that can Gas is advantageous as it is water, a separation layer forming against the existing air, this separation layer sliding upwards in front of you through the Flow the gap until all the air is displaced and is replaced by the gas.
- the by the width of the gap between the Spacer frame and the opposite glass and determined by the entire length of the insulating glass unit maximum inlet cross section for the gas is so large that even with high volume flows for quick fillings of the space with the gas low flow rates can be applied so that annoying Turbulence is prevented and the gas flow remains essentially laminar.
- the gap-forming distance between the one Glass and the spacer frame is advantageously ensured that the still free primary seal on the spacer frame, the one over the other primary seal one glass is pressed, not prematurely with the opposite Glass comes into contact and thereby the sealing effect is reduced during the final pressing. Furthermore, the expected gas loss when filling assuming an optimal seal by the press side Sealant to the volume between the Glass surface and the gap between the glass and the opposite Spacer frame can be limited so that the total loss may be less than 100%.
- the gap is only partially according to claim 2 filled with filling gas before the closing movement takes place, the total gas loss can continue under, for example Be reduced by 10%.
- the gap and that Volume, which through the glass surface and through the press side sealant sealed gap between the glass and the opposite spacer frame is defined as far as filled with gas that the volume contained amount of gas is just sufficient to not yet filled part of the gap during the approach movement the press cheeks by displacing the gas from the Completely fill volume in the space.
- gas loss can almost be counteracted 0% are pressed.
- the gas inlet surface extends at least approximately over the entire lower edge length the insulating glass unit. This is advantageous the largest possible cross section for the Gas so that the flow rate to avoid of turbulence can be reduced. Is further training through this largest possible gas inlet area a homogeneous gas front favors the gas flow.
- the filling process simply perform and regulate quickly.
- the required amount of gas from known sizes such as the density of the gas, the temperature and the Pressure of the gas when filling and the volume of the space certainly.
- the volume of the space can over the glass surface and the thickness of the spacer frame be determined.
- the volume between the glass surface and the spacer frame is off, for example the position of the press cheeks and the aforementioned sizes determinable. This can be used to fill the gap the necessary amount of gas is supplied to the intermediate space, without complex sensor devices for checking of the level were necessary.
- the degree of filling of the space can be determined. By a comparison of the flow of gas and the degree of filling possible leaks through the gas unwanted loss is quickly determined.
- the invention is based on the DE-OS 40 22 185 and solves the task the characterizing features of claim 7.
- the press cheeks with the glasses arranged on them, a glass of which already has the spacer frame, are so far apart that a narrow gap between the one glass and the spacer is available.
- a gas supply device which are arranged in the area of the lower edge of the press cheeks and in the gap between the press cheeks flows, the gas, which is heavier than air, can from flow into the gap through the gap below.
- the Press-side sealants advantageously prevent that the gas can escape sideways.
- At least one of the press side Sealing devices can be moved on a press cheek arranged so that any glass format can be processed can be. thereby forms the immovable Sealing device a stop for one side edge the glasses of an insulating glass unit of any size.
- the then movable sealing device can then against the opposite side edge of the insulating glass unit be moved so that the space laterally is sealed and no gas escapes during filling can.
- it is flush with one press cheek arranged sealing device with the second press cheek, so that a relative movement of the press cheeks on each other not hindered when pressing the glasses is.
- the thickness of the movable Sealing device chosen so that all combinations of Glasses and spacer frames for the common different Insulating glass units processed in the device can be without pressing the glasses by a relative movement of the press cheeks on each other to lock the movement can occur.
- a clean sealing of the side gap against gas leakage is always guaranteed as the sealing device overlapped in alignment with the spacer frame.
- one-piece movable Sealing device means that the thickness is slightly more than a glass thickness plus gap thickness between glass and Spacer frame is.
- a multi-part, for example, labyrinthine movable seal according to claim 10 then at least two slightly parallel to each other Spaced sealing device elements with a Thickness that is less than the total thickness of the pressed insulating glass unit, so that also as a result their overlap to seal the gas well filling space is guaranteed.
- the sealing devices extend according to claim 11 over the entire height of the press cheeks. This is with simple constructive means ensures that a lateral sealing of the space for everyone glass sizes that can be processed by the press is ensured. A complex adjustment to the height of the insulating glass unit can be omitted, which otherwise cause time losses would.
- the gas supply device via a cover, which is preferably band-shaped and is movable like a bellows or a blind covering the open area of the gas outlet to the respective length of the lower edge the glasses limited, so that always exactly the maximum possible Outlet cross section available for the gas stands, regardless of the size of the insulating glass unit. So all common insulating glass units processable on the device according to the invention. The greatest necessary length of the gas outlet opening is due to the largest insulating glass length to be processed certainly.
- the gas outlet opening is also contaminated by possibly falling dirt particles largely also prevents such a cover Homogenization of the flow profile in the area of the gas outlet, i.e. an equalization of the flow direction and the flow velocity over the gas outlet cross section, so that eddies from the start are avoidable.
- Fig. 1 illustrates the arrangement of the glasses in a press for pressing the glasses with the spacer frame, after the space is filled with gas has been used to manufacture insulating glass units.
- the glass 1 with the spacer frame attached to it 2 is by holding devices, not shown arranged on the resting press cheek 8.
- Glass 1 with that on it spacer frame 2 is usually approximately upright over a not closer suitable feed shown, for example a Roller conveyor or a conveyor belt, the stationary press cheek 8 fed and there on its lower glass edge for example supported by roll holders against the press cheek 8 inclined.
- Suction cups, not shown, which, for example, can be integrated into the press cheek 8 can, an immovable positioning of the Ensure glass 1 on the press cheek 8.
- the glass 3 is fed to the press in a similar manner and is arranged on the movable press cheek 9.
- the press cheek 9 also has suitable ones Holding devices, for example, roll holders and / or Suction cups so that the glass 3 approximately parallel to Glass 1 can be arranged opposite this.
- Holding devices for example, roll holders and / or Suction cups so that the glass 3 approximately parallel to Glass 1 can be arranged opposite this.
- the glass 1 with the spacer frame 2 is then by a Gap 11 that between the spacer frame 2 and the Glass 3 is defined, for example glass 3 in parallel spaced.
- Gas flow 10 displaces the space between the Glass 1, the spacer frame 2, the gap 11 and the Glass 3 located air 12, which then through the gap 11th can escape upwards.
- the arrow 13 describes the direction of movement of the Press cheeks towards each other when pressing the glasses with the spacer frame 2 to produce a finished Insulating glass unit after the space preferably completely filled with gas and moving away from each other, around glasses again for a next filling process to be able to record.
- Fig. 2 are two side sealing devices shown that are approximately parallel to each other are arranged vertically.
- a fixed side Sealing device 4 is on one of the press cheeks, for example fixedly arranged on the stationary press cheek 8 and preferably forms one at the same time Stop for the fed glasses in their feed direction.
- the other side sealing device 5 is slidably arranged on one of the press cheeks, for example on the movable press cheek 9 and after the glasses are fed to the press and on the press cheeks have been ordered against those of the fixed Sealing device 4 facing away from the side edge Glasses moved until they touched them sealingly.
- the air 12 therein is by the inflowing gas 10 completely displaced and can through the only remaining opening through the Gap 11 is defined in the upper area of the glasses, escape.
- the fixed lateral sealing device 4 is like this broadly trained to be on the press for everyone processing combinations of glasses and spacer frames is sufficiently thick that the largest possible Distance from the thickness of the glass 1 plus the thickness of the spacer frame 2 plus thickness of the gap 11 plus thickness of the Glass 3 can be covered sealingly.
- the fixed lateral sealing device 4 for example arranged laterally on the fixed press cheek 8, so that there is a closing movement of the press cheeks towards each other not when pressing the insulating glass unit with special needs. You can, for example, on the movable Press cheek 9 can be arranged. The requirement to their width then also follows the considerations mentioned above.
- the movable side sealing device 5 is at least so wide that in the example case the one-piece arrangement on the movable press cheek 9 the greatest possible distance from the thickness of the glass 3 plus thickness of the gap 11 plus a sufficient part of the Thickness of the spacer frame 2 covers and seals a closing movement of the press cheeks when pressing the Glasses with the spacer frame 2 are not obstructed.
- the Sealing device 5 can also be in one piece, for example the fixed press cheek 8 can be arranged. Then the gap 11 is preferably kept smaller than that Thickness of the glass 3 minus the sealing overlap the lateral sealing device 5, so that the approach movement the press cheeks are not hindered.
- multi-part e.g. labyrinth-shaped lateral movable or fixed seal that both on the movable as well as on the stationary press cheek can be arranged then apply to their width essentially also the considerations set out above.
- the gas supply device 6 extends at least over part of the press cheeks 8 and 9, preferably over the full length of the press cheeks, thus also the largest glasses along their entire length of the bottom Glass edge can be filled with gas 10, and around the To be able to keep gas outlet opening 14 as large as possible. Through the largest possible gas outlet opening 14 the shortest possible filling time can be realized.
- the Gas supply device 6 or the gas outlet opening 14 can be shorter or smaller than the length if necessary the lower edge of the glass can be held, but what below Under certain circumstances the filling time is extended or the homogeneity the gas flow in the space between the insulating glass unit reduced.
- the gas supply device 6 also has a sliding cover 7, for example one Venetian blind or bellows, so the length of the gas outlet 14 with constant size of the gas supply device 6 adapted to the lower edge length of the glasses can be. This ensures that the Gas outlet opening 14 only over the area of lower glass edge despite changing glass sizes.
- the sliding cover 7 can for example with the movable side sealing device 5 be coupled so that both are preferably at the same time and together to the respective position of the one to be sealed lateral glass edge can move.
- the Cover 15 of the gas supply device 6 prevents, on the one hand, that dirt or possibly through never completely glass splinters to be excluded can penetrate into the gas supply device 6 and, on the other hand, ensures through its structure that the inflowing gas over the cross section of the gas outlet opening 14 a speed profile that is as uniform as possible with constant flow velocity and has an approximately parallel flow, so no turbulence can arise and a largely loss-free filling of the space between the insulating glass unit is further improved with gas.
- the invention thus provides a method and a Device for filling a space between two glasses 1 and 3 of a disc-shaped insulating glass unit with a primary seal located between the glasses having spacer frame 2, with Filling gas in a press to seal the two glasses 1 and 3, in which the glasses are parallel to each other be arranged on press cheeks 8 and 9, wherein one of the glasses has the spacer frame 2, and in which the glasses are closed by a closing movement of the press cheeks 8 and 9 with the interposition of the spacer frame 2 are joined together, the filling gas 10 before along the complete movement of the press cheeks the lower edge of the glasses through a gap 11 between the spacer frame 2 and the opposite Glass 3 is introduced, and wherein the gap 11th between the spacer frame 2 and the opposite Glass 3 along the two upright sides of the Glasses against press side sealants 4 and 5 against an outlet of filling gas 10 is sealed.
