Description

 Method for producing an insulating glass pane

The invention relates to a method for producing an insulating glass pane and to a system comprising an insulating glass pane and at least one

Closure element.

Insulating glasses are often filled with a special gas to improve the technical insulation during their use. The filling of

Insulating glass panes are made either directly in the manufacturing process of

Insulating glass production or after insulating glass production by filling via gas filling holes. A common gas used for filling is argon and / or krypton.

The above-mentioned Befüllöcher be after filling by a

Sealant, usually butyl, sealed, as described for example in EP 0 324 333 A2.

Such butyl gaskets may be comparatively highly visible (depending on the material of spacers used in the insulating glass pane). This is often criticized by the customer or, in extreme cases, rejected.

In EP0185222 A2, DE2918581 AI and DE8426427 Ul closures and caps are disclosed with other bodies.

The invention is based on the object, an improved method for

To propose an insulating glass pane, which is based on simple and

in particular visually appealing manner allows a filling of a cavity with a gas. Accordingly, an improved system, comprising an insulating glass pane and at least one closure element to be proposed, in a simple manner and in particular with optical

appealing result should be produced. Furthermore, a device for carrying out the method or production of the system is to be proposed. According to the invention, this object is achieved by a method for producing an insulating glass pane according to claim 1. The invention also relates, according to the further independent claims, to a system comprising one

Insulating glass pane and at least one closure element, a device for carrying out the method and / or for producing the system and the use of a closure element.

According to a first aspect of the invention, the object is achieved by a method for producing an insulating glass pane, wherein the insulating glass pane has at least one cavity, which is filled via at least one opening with a gas and / or emptied via at least one opening, wherein the opening after the filling and / or emptying is closed with at least one closure element which has a (in a state before it is brought into the respective opening) dimensionally stable base body.

A core idea of the invention is to suggest a closure element which has a dimensionally stable base body. As a result, a gas to be filled (or to be emptied) cavity can be closed in a simple manner. The material of the closure element (in particular a section facing inward or visible from an observer looking at the pane from inside) may be chosen such that it corresponds to or at least matches the surrounding material (usually a spacer). As a result, the overall visual impression can be improved. Another idea of the invention is to propose a closure element which allows an improved sealing of an insulating glazing. For this purpose, the closure element may comprise a butyl component. When inserted into the opening can through the

Presence of the butyl component improved sealing of the opening can be achieved. Compared to a method in which a sealing component must be arranged in the opening or in the cavity boundary, the use of a closure element with butyl component is much easier to perform. The closure member for the cavity of the insulating glass pane as such having the above (and hereinafter) described features is another

independent aspect of the invention.

Preferably, the cavity is filled with argon and / or krypton. The opening may have a diameter of at least 2 mm ² , preferably at least 10 mm ² and / or at most 50 cm ² , preferably at most 10 cm ² . A portion of the closure member occluding the opening may have a cross-section with a surface that meets the above values with respect to the aperture

equivalent. If a plurality of openings are provided, these can each have their own closure element or a common closure element

be closed. Insofar as a common closure element is present, it can then optionally be formed in one piece (but in particular with delimited closure sections). It can / may be provided (exactly) one cavity or more cavities. For example, it may be at the

Insulating glass pane act around an insulating glass pane with three individual panes, wherein on both sides in relation to a central single pane one cavity each is formed (by an outer pane in each case). Openings that are different

Cavities are assigned, in turn, by (own)

Closing elements are closed or possibly by a common

Closure element.

Under a dimensionally stable body is in particular a section of the

To understand closure element that (in particular, in a state before it is placed in the respective opening) maintains its shape (at least largely), so in particular is not pasty or liquid. However, this does not exclude that sections may also be non-dimensionally stable or at least be brought into a non-dimensionally stable state (eg by heat application), in particular to the closure element in relation to the other components of the insulating glass pane (in particular a spacer ) seal. A weight of the main body preferably accounts for at least 20%, more preferably at least 50%, even more preferably at least 70%, even more preferably at least 90%, of the total weight of the closure element. Optionally, the entire closure element can be dimensionally stable. The main body preferably penetrates the respective opening completely. When

Material for the main body is in particular (solid) plastics and / or metal (such as steel and / or aluminum and / or an aluminum alloy) in question. Optionally, the closure element may comprise a plastic component and a metal component. For example, a

The main component of the main body is made of plastic (eg more than 50% by weight or 80% by weight or more than 90% by weight of the main body). Furthermore, a metal coating (in particular on a surface of the closure element facing outward in the assembled state) can be provided. Such

Metal coating takes over the function of a gas-tight and

moisture-proof barrier. Optionally, an inwardly facing portion of the closure element of a different (plastic) material than the other components. This inwardly-facing portion may be at least 0.1% by weight, preferably at least 1% by weight and / or less than 20% by weight, preferably less than 10% by weight, of the total weight of the closure element. By such a material distribution on the one hand, the inward-facing portion (in particular optically) can be matched to a spacer used and on the other hand for the other (optically less relevant) components a correspondingly low-cost or on the respective

Use purpose adapted material are used. The inner one

End portion may be, for example, that portion which by a

Inner wall of a spacer (or spacer frame part) penetrates.

Preferably, a gas-tight and moisture-proof barrier is arranged on an outwardly facing surface of the closure element. The gas-tight and moisture-proof barrier on the closure element improves the tightness of the system and simplifies the process, since a subsequent sealing with a film or coating is no longer necessary. In this case, the outside refers to the position in the finished insulating glass pane and refers to the part of the closure element which points in the direction of the external environment, ie not in the direction of the cavity of the insulating glass pane. Preferably, at least one inlet opening for filling the cavity with gas and an outlet opening for removing gas from the cavity is provided. As a result, for example, a gas previously taken up in the cavity (such as, for example, air) can be replaced by an insulating gas (eg, argon and / or krypton) in a simple manner.

At least one inwardly facing surface of the closure element preferably has the same color as a cavity boundary, in particular in the form of a spacer. Alternatively or additionally, an inwardly facing surface of the closure element may be formed of the same material as a cavity boundary, in particular in the form of a spacer. This further improves the overall visual impression.

In one embodiment, precisely one opening of the cavity is closed by a single, specific closure element.

Alternatively or additionally, preferably two or more openings of the same or different cavities, in particular two cavities defined by a double spacer (double spacers), can be closed by (only) one (possibly individual) closure element. Thus, the method simplifies the closure of two openings, since only a single closure element must be used in a single process step. By contrast, two method steps are required when using two individual closure elements. The double spacer may preferably be configured to be configured to form a triple insulating glazing. For example, two outer disks can be provided on two (opposite) outer sides of the double spacer and a third (middle) disk in one

(In particular central) recess of the double spacer are added.

The closure element is preferably received by a suction device and / or brought to the opening (to arrange it for closing the opening). This allows the closure element to be integrated in a simple and effective manner. Preferably, a plurality of closure elements is provided in a (in particular stackable) receiving tray. Possibly. a plurality of receiving trays can be provided (and in particular stacked). For example, the closure elements may be arranged in a regular pattern (eg, in columns and rows or in a hexagonal pattern) in the respective receiving tray. In a receiving tray, for example, at least four or at least 10 or at least 20 shutter elements can be recorded. Overall, this can easily a variety of

Closing elements are provided, whereby the process can be simplified and accelerated.

Preferably, the closure element is received by a holding device, in particular the above suction device, and / or brought to the opening, wherein the holding device is heated. The holding device can be heated, for example, from the outside (and correspondingly have at least one section for receiving heat). Optionally, the heating device may also be designed so that it can be actively heated (eg by providing an electrical heating resistor, such as a heating coil and / or an electrical heating coating). By such a heatable holding device can be heated in a simple manner, the closure element, so that an arrangement in the corresponding opening (or the corresponding

Openings) can be improved. For example, by heating, a dimensionally stable material can be softened, so that it can be (more easily) introduced into the opening (for example, pressed in). Optionally, meltable portions can be melted by the application of heat, so that an improved seal with the opening can be realized.

In general, a component (in particular butyl component) of the closure element in a liquid or pasty state to the opening

introduced. Alternatively, a component, in particular butyl component, can be present in the opening in a liquid or pasty state or be converted into a liquid or pasty state. Then the component (Butyl component) are solidified to seal the closure element. Preferably, the component (butyl component) is part of the

Closure element. Alternatively, it is also conceivable that such

Component (butyl component) is present as part of the spacer or is provided in the form of a separate element. In the preferred

Execution in which the component (butyl component) is part of the

Closure element is, this component (butyl component) is preferably materially connected to the closure element (or the rest of the closure element or a main body of the closure element). The component (butyl component) may preferably run like a ring (possibly with interruptions) on an edge of the closure element, this edge preferably being the edge coming into contact with a spacer (in particular an outer side of the spacer). In any event, such a component (especially butyl component) may allow (eg, by reflowing) to seal the closure member from the opening (particularly an opening of a spacer). in the

In general, the component (butyl component) between spacers (in particular an outer surface of the

Spacer) and closure element (in particular a mushroom or plate-like extension of the same) are located.

The closure element may preferably have a mushroom-like portion from which extend one or more portions which penetrate (in the assembled state) the respective opening. In general, that can

Closure element have an extension which is located (in the mounted state) outside the opening and at least partially exceeds a width of the opening and / or adjacent to the opening portions (surrounding portions).

The opening and / or a portion of the housing to be received in the opening

Closure element may have a (circular) round or oval or elliptical or polygonal (in particular square, preferably rectangular, more preferably square) cross-section. Alternatively or in addition to a seal via a component (eg butyl component), which may be in a liquid or pasty state, sealing by means of O-rings (for sealing between closure element and corresponding opening or corresponding spacers) can be realized become.

In principle, the cavity is preferably of at least one

Spacers limited. The spacer may be formed, for example (at least in sections) as a tube (possibly frame tube). Farther

(In particular, in the form of a tube), the spacer may have an inner wall (immediately adjacent to the cavity) and an outer wall. The opening or openings in the spacer then preferably extend through both the outer wall and the inner wall.

In embodiments, at least one opening is disposed in a spacer (s). The opening preferably has an outer (eg, circular) aperture and an inner (eg, circular) aperture. The outer breakthrough, for example, through the outer wall of the

Go spacers. For example, the inner breakthrough may pass through the inner wall of the spacer. Furthermore, the inner opening may have a smaller diameter than the outer opening (so that the opening tapers in total from outside to inside). In general, such a taper can be done in other ways (from outside to inside). Specifically, the one or more of the opening (s) can be introduced by a tapered, in particular stepped, drilling tool. In a specific embodiment, the inner opening is introduced through a front (narrower) section of the boring tool (in particular into the inner wall of the boring tool)

Spacer). The outer breakthrough is followed by a wider (laterally delimiting from the narrower section) section

introduced, in particular in the outer wall of the spacer. Overall, it can thus be provided in a simple manner, a structure that allows a seal with a correspondingly corresponding closure element in a simple manner. According to a further aspect of the invention, a system comprising an insulating glass pane and at least one closure element is proposed, wherein the insulating glass pane has at least one cavity which can be filled with a gas via at least one opening and / or can be emptied via at least one opening, wherein the opening is closed or closable with the closure element, wherein the closure element has a dimensionally stable (in a

Condition before it is brought into the respective opening) basic body. In the state in which the opening is closed with the closure element, the system can also be referred to as (insulating) gas-filled or emptied insulating glass pane. In general, with regard to the term "insulating glass pane", a distinction can be made between a state in which no (insulating) gas has yet been filled or emptying has yet taken place and a state in which an (insulating) gas is filled or an emptying has taken place and thus defines a state in which the insulating glass pane can then also be mounted (eg on the construction site).

In a preferred embodiment of the system comprising a

Insulating glass pane may be arranged at the opening a butyl component as part of the closure element or be arrangeable. This has the advantage that the opening is better sealed by the closure element and thus the tightness of the system is improved. In a preferred embodiment, the butyl component is materially connected to the closure element (or the rest of the closure element or a main body of the closure element).

In a preferred embodiment, the butyl component extends in an annular manner (possibly with interruptions) on an edge of the closure element, this edge preferably being that edge which is in contact with a spacer

(In particular, an outside of the spacer) comes.

In a further preferred embodiment, the butyl component is arranged in the form of a butyl layer on the outwardly facing surface of the closure element, wherein the butyl layer protrudes beyond the main body of the closure element, so that the butyl layer in contact with a spacer (In particular, an outside of the spacer) comes. This achieves a simple and good seal.

In a further preferred embodiment is a gas-tight and

moistureproof barrier on the outward facing surface of the

Arranged closure element. Thus, the escape of an optionally present gas filling is prevented and the penetration of moisture into the cavity of the insulating glass pane is reduced.

In a further preferred embodiment, the butyl component is in the form of a butyl layer on the entire outwardly facing surface of the

Arranged closure element. In this case, the butyl layer protrudes beyond the main body of the closure element, wherein the butyl layer is covered with a gas-tight and moisture-proof barrier. The barrier faces outward in this case. Thus, at the same time a good seal can be achieved by the butyl, which extends beyond the body, and the barrier on the butyl layer additionally improves the tightness of the system. The butyl layer is covered with the barrier, so that the closure element in the process is also easy to handle since the sticky, pasty butyl is covered by the barrier.

The gas-tight and moisture-proof barrier is preferably a barrier film. The barrier film prevents moisture from entering the cavity of the spacer. The barrier film may be a metal foil or polymer film. The barrier film is preferably a multilayer film with polymeric and metallic layers or with polymeric and ceramic layers or with polymeric, metallic and ceramic layers. Preferably contains the

Barrier film at least one polymeric layer and a metallic layer or a ceramic layer. Preferably, the layer thickness of the polymeric layer between 5 μιτι and 80 μιτι, while metallic layers and / or ceramic layers are used with a thickness of 10 nm to 200 nm. Within the stated layer thicknesses, a particularly good tightness of the barrier film is achieved. Particularly preferably, the barrier film contains at least two metallic layers and / or ceramic layers, which are arranged alternately with at least one polymeric layer. In this case, the outer layers are preferably formed by the polymeric layer. The alternating layers of the barrier film can be bonded or applied to one another in a variety of methods known in the art. Methods for the deposition of metallic or ceramic layers are well known to those skilled in the art. The use of a barrier film with alternating layer sequence is particularly advantageous in terms of the tightness of the system. An error in one of the layers does not lead to a loss of function of the barrier film. By comparison, even a small defect in a single layer can lead to complete failure. Furthermore, the application of several thin layers compared to a thick layer is advantageous, since the risk of internal adhesion problems increases with increasing layer thickness. Furthermore, thicker layers have a higher conductivity, so that such a film is thermodynamically less suitable.

The polymeric layer of the barrier film preferably comprises polyethylene terephthalate, ethylene vinyl alcohol, polyvinylidene chloride, polyamides, polyethylene, polypropylene, silicones, acrylonitriles, polyacrylates, polymethyl acrylates and / or copolymers or mixtures thereof. The metallic layer preferably contains iron, aluminum, silver, copper, gold, chromium and / or alloys or oxides thereof. The ceramic layer of the film preferably contains silicon oxides and / or silicon nitrides.

In an alternative preferred embodiment, the gas-tight and moisture-proof barrier is a metal coating (in particular on a surface of the closure element facing outward in the mounted state).

The insulating glass pane preferably has at least one inlet opening for filling the cavity with gas and an outlet opening for removing gas from the cavity. The opening / openings and / or a section of the closure element to be received in the respective opening may have a (circular) round or oval or elliptical or polygonal (in particular quadrangular, preferably rectangular, still more preferably square) cross-section.

At least one inwardly facing surface of the closure element may have the same color and / or be formed from the same material as one

Cavity limitation, in particular in the form of a spacer. Two or more openings of the same or different cavities, in particular of two cavities delimited by a double spacer, can by (only) one

Closing element to be closed or closed. In and / or at the opening, a component (in particular butyl component), preferably as

Be arranged part of the closure element or be arrangeable, wherein the component is present in a liquid or pasty state or in such a state, in particular by heat application can be transferred.

According to a further aspect of the invention, an apparatus for the

Implementation of the above method and / or for the production of the above system (or for producing a filled with (insulating) gas or (partially) emptied insulating glass pane) proposed. The device can in particular a

Have means for receiving (holding) an insulating glass and a means for holding (recording or attachment) of the closure element in / at the opening of the insulating glass pane. The latter device may in particular comprise a suction device. Furthermore, the device may comprise a device for filling the cavity with gas and / or for emptying the cavity.

According to a further aspect of the invention, the use of a

Closure element with a dimensionally stable base body for closing an opening of a cavity of an insulating glass pane (in particular the above

described type) proposed. The closure element used preferably has the features described above (and / or below).

Overall, the appearance of a neutral closure element

(Closure piece) are present, which contributes to a visually appealing overall impression. The closure element (closure piece) can have a material in a section (part) facing toward a (window) interior, which has a material

Spacer material corresponds. In particular, by a (geometrical) fit and possibly by a corresponding (suitable) material, a (neutral) appearance appealing (neutral) can be achieved closure, which may correspond to the appearance of "filled in line" insulating glass (or at least can come close). A complaint for this reason is therefore not (more) to be expected from the end customer side.

The closure element (closure piece) according to the invention is preferably an element for closing a double spacer (or openings within the double spacer), as can be used in the production of triple glazing. Such a spacer type can be produced in the manufacturing process of a frame with the corresponding (filling) holes and possibly filled after the production of insulating glass with the (functional) gas.

Another aspect of the invention is the provision of the closure elements (closure pieces) in specially provided (shaped) receiving trays, in addition to the actual plant for the production of insulating glass panes

(stackable) can be prepared and possibly allow automatic installation (assembly) of the fasteners. Each receiving tray may have sufficient capacity to accommodate a stacking of multiple trays

Cover production layer.

The closure pieces are preferably shaped so that they can be easily absorbed by a suction head of a handling device (handling machines). By means of a preferably provided integrated heating in the suction head, sealing via a butyl component integrated in the closure element (closure piece) can be reliably possible.

Fig. 1 shows an inventive closure element 10 in an oblique view. The closure element 10 has a main body 11 and a sealing material (butyl) 12a, 12b. The main body 11 has a base plate 13 from which protrude (in the present case two) projections 14a, 14b. The projections point at a respective end remote from the base plate 13 of the projections

Rejuvenations 15a, 15b. Both the projections 14a, 14b (without the Tapers 15a, 15b) as well as the tapers 15a, 15b are (at least substantially) cylindrical (circular-cylindrical), wherein the tapers 15a, 15b define in particular a comparatively flat cylinder (whose axial extent is smaller, for example around 50) %, possibly 80% lower, is considered a

Diameter of the rejuvenation).

The tapers 15a, 15b are preferably made of a material corresponding to the spacer material (described below). The portions of the projections 14a, 14b (without the tapers 15a, 15b) may be made of another material (eg, a suitable plastic). The sealing material 12a, 12b runs (at an inner or the one described below

Spacer facing surface of the base plate 13) around the projections 14a, 14b around. On an outer surface or the spacer facing away from a (thin) metal coating 16 is provided as a gas-tight and moisture-proof barrier.

FIG. 2 shows a cross section through the closure element 10 according to FIG. 1 together with a corresponding cross section of a spacer 17 (in the present case, in practice, a double spacer). In the state shown in FIG. 2, the closure element 10 closes the spacer 17 penetrating the spacer

Openings 18a, 18b. The tapers 15a, 15b are concretely in

Inner walls 19 a, 19 b of the spacer 17 are arranged. Overall, the projections 14a, 14b completely penetrate the respective opening 18a, 18b.

The spacer 17 or its openings 18a, 18b are sealed relative to the closure element 10 by means of the sealing material 12a, 12b.

In Fig. 3a are cutouts of another embodiment of a

Closing element 10 and sections of the spacer in an oblique view (partially cut) shown. There is in particular the arrangement of

Seal material (here butyl layer 24) recognizable. The Buytlschicht 24 is disposed on the entire outwardly facing surface of the closure element 10 and the base plate 26 and projects beyond the base plate 26 also. In FIG. 3b, the spacer 17, together with the closure element 10, is arranged between two individual elements. Disks 21, 22 visible. A third (not shown) single-disc may optionally be arranged in a recess 23 (in a central portion) of the spacer 17, to possibly form a triple-glazing. 20a, b indicate adhesive between spacers 17 and single discs 21 and 22.

4 shows a side view of the closure element according to FIGS. 3a, 3b in a state before a corresponding opening (or corresponding openings) of a spacer element is (are) closed. According to FIG. 4, a base plate 26 may (at least in an initial state) be curved (or concave) and possibly have two layers, namely the butyl layer 24 and thereon a metal layer 25 as a gas-tight and moisture-proof barrier (above or outside of a Basic body of the base plate 26).

FIG. 5 shows a suction device 27 for receiving the closure element 10 according to FIG. 4. The suction device 27 has a suction channel 28, via which a negative pressure between suction device 27 and closure element 10 can be produced, so that the closure element 10 is lifted via the suction device 27 (and the insulating glass pane or their spacers) can be transported. Heating can take place via one or more heating zones 30.

Fig. 6 shows a receiving tray 29a (sections) and a receiving tray 29b (also in sections). In the receiving tray 29a (as well as what is not seen in Fig. 6, in the receiving circuit 29b) is arranged a plurality of shutter members 10, so that a respectively required

Closing element 10 can be received by the receiving tray 29a (in particular by the suction device according to FIG. 5) and can be arranged on or in an opening of an insulating glass pane (for closing the same).

Fig. 7 shows an alternative embodiment of an inventive

Closure element in an oblique view. This closure element is provided for closing only one opening (see also FIG. 11). In contrast to the previous embodiments, the closure element according to FIG. 1 only a projection 14a and only one taper 15a. These are otherwise (at least in principle) as in the previous embodiments.

Accordingly, only one sealing material 12a (butyl) is provided. To the

Projection 14a adjoins an (outwardly arched, flange-like) extension 34, which in turn (on the outside) has a fluid-tight (watertight) film (layer) (gas-tight and moisture-proof barrier) 35.

The closure element according to FIGS. 7 and 8 can be inserted into a spacer according to FIG. 10, as shown in FIG. 11. In order to provide the opening 18a in the spacer according to FIG. 10, the drilling tool 33 according to FIG. 9 can be used. The drilling tool 33 has a step 36 which delimits a narrower section 37 from a wider section 38. The narrower section 37 may create an internal aperture (bore) 32 (see FIG. 10). The wider portion 38 may create an outer aperture 31 (bore). As a result, the inner opening 32 is narrower than the outer opening 31. Specifically, the inner opening 32 is located in an inner wall 39 of the

Spacer 17 and the outer opening 31 in an outer wall 40 of the spacer 17 (see Fig. 10). Overall, this can be defined in a simple manner, a stepped or tapered structure, which allows a simple way a recording of the closure element.

In particular, in a simple and well-defined manner, the taper 15a (see FIGS. 8 and 11) can be received in the inner wall 39 of the spacer 17 (flush). This simplifies manufacture and sealing.
