Definitions
- the invention relates to a method and a device for producing insulating glass panes from at least two glass plates, between which an elastoplastic band is arranged as a spacer.
- the spacers between an insulating glass unit comprising two or even more glass panes usually consist of aluminum or hollow steel profiles.
- a spacer in the form of a strip with a rectangular cross section which is often referred to as a "swiggle strip"
- a spacer in the form of a strip with a rectangular cross section, which is often referred to as a "swiggle strip”
- This band-shaped spacer based on butyl rubber is tough-plastic, highly adhesive (which is desirable to achieve a gas-tight connection with the first and later the second pane of the insulating glass unit) and has a strongly temperature-dependent viscosity.
- the adhesive applied to the two narrow sides of the tape is not water vapor diffusion-tight. Therefore, after assembling the insulating glass pane, the remaining edge joint must be filled with a sealing compound that ensures the imperative of water vapor diffusion tightness, because otherwise water vapor will penetrate into the closed interior of the insulating glass pane over time and inevitably lead to the formation of condensed water and thus to the unusability of the Disc leads. Suitable edge joint fillers are expensive and are required in large quantities because of the considerable cross-section of the edge joint.
- the invention has for its object to provide a more cost-effective method for producing insulating glass panes and a device which is particularly suitable for carrying out the method.
- an elastoplastic tape is assumed, the side surfaces of which have not yet been coated with an adhesive. Rather, it is only applied to the two side surfaces shortly before the tape is applied.
- Another advantage is that the corresponding adhesive or protective films are also saved with the factory adhesive coating of the side surfaces of the tape. In addition to the reduction in the production costs of the tape, it is particularly important that the devices for applying the tape to the first glass pane make the previous devices for removing the protective films and for winding them up for the purpose of proper disposal superfluous.
- a butyl adhesive is preferably used as the adhesive (claim 2), as it has already proven itself for coating the side surfaces of spacer frames made of hollow metal profiles.
- the band is preferably placed on the first glass pane by means of an independently operating application station and pressed onto it (claim 3).
- the amount of adhesive applied to the tape is expediently regulated depending on the tape transport speed (claim 4), etc. so that the adhesive layer thickness is as constant as possible. This can be achieved by keeping the amount of adhesive used per unit time for the job proportional to the tape transport speed, i.e. going to zero especially when the tape is at a standstill.
- the thickness of the adhesive coating is independent gig of the transport speed kept approximately constant (claim 5).
- the latter can be achieved in particular by measuring the actual value of the thickness of the coating and using the deviation from a predetermined desired value as an error signal to keep the coating thickness constant (claim 6). Suitable layer thickness measurement methods are known per se.
- the object on which the invention is based is further achieved with a device which comprises a supply reel for the band, a plurality of driven band guide rollers and a pressure head for the band which is movable relative to a first glass pane, in that opposing ones between the supply reel and the pressure head Nozzles for coating the side surfaces of the tape with a water vapor diffusion-tight adhesive are arranged (claim 7).
- the coating nozzles can in particular be assigned means for controlling the adhesive flow as a function of the tape transport speed (claim 8).
- At least one first pair of rollers can be arranged in front of the coating nozzles for lateral guidance of the belt (claim 9).
- a height guide for the tape can be arranged in front of the coating nozzles (claim 10), which may only consist of a simple, horizontal support web, a support roller on which the tape rests, or a pair of rollers between which the tape runs through, can exist.
- pairs of rollers can also be arranged after the coating nozzles for lateral guidance of the tape, the rollers of which then expediently touch the tape only at the edges of the tape side surfaces (claim 11) in order to prevent the rolls from becoming contaminated by the freshly applied adhesive layer and vice versa to avoid damaging the latter.
- an adhesive strand can be applied centrally to each of the side faces of the tape, the cross-section of which is dimensioned such that a uniform adhesive layer forms when the tape is pressed onto the first glass pane or when the second glass pane is pressed onto the other side face of the tape, without the adhesive swelling over the edges of the tape side surfaces.
- the coating nozzles as slitting nozzles (claim 12).
- the slot width of the coating nozzles can be smaller than the width of the side surfaces of the tape (claim 13), so that the respective coating does not reach all the way to the edges of the tape side surfaces, provided the adhesive is not applied too richly.
- a device for measuring the thickness of the coating which regulates the flow of adhesive through the coating nozzles, can be arranged after the coating nozzles, based on the tape transport direction (claim 14).
- the method according to the invention is explained below by way of example with reference to the drawing, which is to be understood purely schematically. It shows :
- Figure 1 is a greatly simplified side view of a device for applying a spacer tape
- Figure 2 shows the spacer tape in cross section between the coating nozzles on a greatly enlarged scale
- Figure 3 is a downstream pair of rollers for lateral guidance of the belt, also on an enlarged scale.
- an elastoplastic band 1 with a rectangular cross section is pulled off a supply reel 2, which is seated on a driven shaft 3, via indicated guide rollers 4 and a displacement measuring device 5.
- the tape 1 runs into a coating station 10 which is connected via a line 14 to a pump 15 on a container 13 containing a butyl adhesive.
- Pair of rollers 6 for lateral guidance of the now coated tape This is followed by a stretch in which the belt 1 sags freely.
- the sag is kept between an (upper) minimum value and a (lower) maximum value by a lower sensor 30 and an upper sensor 31, which are connected to the machine control (not shown) via the indicated signal cables, and so on. in such a way that the machine control acts on the corresponding reel and roller drives as a function of the signals from the sensors 30 and 31.
- This ensures that the belt is free of longitudinal tension, ie neither compressed still stretched over further pairs of rollers such as 7 and 8, it then runs into an only indicated application head 20 which can be moved on a column 22 in the direction of the double arrow on a column 22.
- the column 22 is slightly inclined to the vertical and parallel to a conventional support wall 23, for example an air cushion support wall, which rests on a machine frame 24.
- a glass plate 40 leans against the support wall 23, the lower edge of which stands on the indicated roller conveyor 25.
- a vacuum conveyor 26 which is known per se and which can be displaced on horizontal bars 27, the glass plate 40 can be transported in a reversible manner.
- the pressure head 20 is in turn turnable about an axis perpendicular to the column 22.
- the band 1 is pressed all around the edge against the glass plate 40, as is known per se.
- FIG. 2 schematically shows the nozzles 11 and 12 arranged in the coating station 10 for applying the butyl adhesive to the side surfaces of the strip 1.
- the flow of the butyl adhesive through each of the nozzles 11 and 12 is such by means of slides 11.1 and 12.1 driven by servomotors Controllable or regulatable that the side surfaces of the tape 1 with an adhesive layer 1.1 or 1.2 are essentially constant, ie of the instantaneous speed of the strip 1 of independent thickness can be coated.
- the drive motors of the slides 11.1 and 12.1 and possibly downstream thickness measuring devices are connected to the machine control system (not shown).
- Nozzles can be moved according to the double arrows to adapt the distance between their mouths to strips of different widths.
- At least the roller pairs downstream of the coating station 10, such as 6 and 7, are the guide of the belt 1 is provided with a wedge-shaped profiled running surface, so that the rollers 6.1 and 6.2 shown only touch the belt at the edges of the belt side surfaces.
- the rollers for example the rollers 6.1 and 6.2, can be designed to run freely or sit on the shafts of drive motors, not shown, which keep the peripheral speed of the rollers synchronous and in accordance with the instantaneous or the instantaneously required tape running speed.
