Definitions

  • the invention relates to a method and an apparatus for producing insulating glass panes from at least two glass plates, between which an elastoplastic strip is arranged as a spacer.
  • the spacers between a two or more glass panes comprising insulating glass unit made of aluminum or steel hollow sections.
  • the spacer of aluminum or plastic hollow profiles is composed and has a (weak) stepped rectangular cross-section.
  • the strip-shaped side surfaces intended to rest against the first and the second glass plate are each provided with a transparent adhesive tape for provisional fixing of the spacer.
  • the outwardly facing surface of the spacer frame is flush with the outer edges of the glass plates.
  • substantially less temperature-sensitive elastomeric spacer tapes based on polyurethane or the like have been developed, which also have a rectangular cross-section, are dimensional and dimensionally stable than the so-called "swiggle strip" on which later outer side have a lamination of aluminum foil and on the two sides intended for bonding with the glass sheets narrow sides are provided by the manufacturer with a thin, covered to apply with protective films coating of a highly adhesive adhesive.
  • a method and a device for applying such a strip to at least the first glass plate of an insulating glass unit consisting of at least two such glass plates are known.
  • the invention has for its object to improve this latter method and to provide a device particularly suitable for carrying out the improved method.
  • an elastoplastic strip does not have a normal rectangular cross section but a (weakly) stepped rectangular cross section or a trapezoidal cross section.
  • Each of the two side surfaces therefore consists of two strip-shaped partial surfaces, of which the part of the larger width of the band corresponding surface is preferably already factory-coated with the highly adhesive adhesive with a thickness of usually much less than 1/10 mm, while the other, on the other hand, reset or deeper strip-shaped partial surface then in the delivery state of the tape is adhesive-free.
  • a second adhesive is applied to the bilateral, deeper-lying strip-shaped partial surfaces of the side surfaces, which ensures the necessary water vapor diffusion tightness.
  • the layer thickness of this adhesive is usually in the range of a few tenths of a millimeter.
  • the band is narrower in the region of the two-sided partial surfaces, so that the application of the second adhesive at least approximately equalizes the step between the two partial surfaces.
  • the highly adhesive, film-like adhesive ensures that the tape adheres exactly and immovably in its predetermined position on the first glass and the second adhesive ensures the diffusion-tight connection of the tape or spacer with the glass. The same applies to the placement of the second glass pane and the compression of the unit. Subsequently, the remaining edge joint is filled as before with a sealant, but which does not have to be water vapor diffusion tight and therefore can be cheaper than the previously required sealing compounds.
  • a butyl adhesive is used as the adhesive, as he has already proven to coat the side surfaces of said spacer frame made of metal hollow sections.
  • the band is preferably placed on the first glass pane by means of an automatically operating application station and pressed against it.
  • the applied to the tape amount of adhesive is suitably regulated as a function of the tape transport speed, uzw. so that the result is a very constant adhesive layer thickness. That's possible achieve that the amount of adhesive consumed per unit of time for the job is kept proportional to the tape transport speed, that is to say zero, in particular when the tape is at a standstill.
  • the thickness of the adhesive coating is kept approximately constant regardless of the transport speed.
  • the latter can be achieved, above all, in such a way that the actual value of the thickness of the coating is measured and the deviation from a predefined setpoint value is used as an error signal for keeping the coating thickness constant.
  • Suitable layer thickness measuring methods are known per se.
  • the object underlying the invention is further achieved by a device comprising a supply reel for the band, a plurality of driven tape guide rollers and a movable relative to a first glass pressure head for the tape, characterized in that between the supply reel and the pressure head opposing nozzles for Coating the deeper, strip-shaped faces of the side surfaces of the belt are arranged with a water vapor diffusion-tight adhesive (claim 7).
  • the coating nozzles are assigned means for controlling the adhesive flow as a function of the belt transport speed.
  • At least a first pair of rollers for the lateral guidance of the tape can be arranged.
  • a height guide for the band may be arranged, which may consist only of a simple, horizontal support web, a support role on which the tape rests or from a pair of rollers, between which the tape passes, if necessary.
  • the coating station is not integrated in the pressure head, can be arranged based on the tape transport direction, even after the coating nozzles for lateral guidance of the tape roller pairs whose roles then suitably touch the tape only at the edges of the belt side surfaces to contamination of the rollers the freshly applied adhesive layer and vice versa to avoid the damage last.
  • each of the partial surfaces of the side surfaces of the tape centrally a strand of adhesive whose cross-section is dimensioned so that when pressing the tape to the first glass or when pressing the second glass to the other side surface of the tape a uniform adhesive layer forms without glue over the edges of the belt side surfaces swells.
  • the slit width of the coating nozzles may be smaller than the width of the relevant partial surfaces of the side surfaces of the belt, so that on the condition of not too abundant adhesive application, the respective coating does not reach all the way to the edges of the belt side surfaces.
  • a device for measuring the thickness of the coating can be arranged, which regulates the adhesive flow through the coating nozzles.
  • FIG. 1 is an elastoplastic tape 1 with the in Fig. 2 illustrated, stepped rectangular cross-section of a supply reel 2, which sits on a driven shaft 3, deducted via a displacement measuring device 4 and indicated guide rollers 5.
  • the two side surfaces of the bottom are based Fig. 2 to 4 Tape 1 described in more detail, each with a protective film 1a, 1b (see. Fig. 2 ), which are deducted before or after the displacement measuring device 4 and the Disposal can be wound up. This is known and therefore not shown.
  • the belt 1 passes into a coating station 10, which is connected via a line 14 to a pump 15 on a container 13 containing a butyl adhesive.
  • the apparatus also includes a station for applying the highly adhesive film-like adhesive 50 in FIG Fig. 2 and the following. Then the tape is delivered glue-free and without protective films.
  • the coating station 10 can also be integrated in the pressing head 20, so that the coating with the butyl adhesive takes place only immediately before the band is pressed against the glass plate 40.
  • FIG. 2 shows a cross section through the belt 1 in the delivery condition, so usually rolled up on the reel 2 in FIG. 1 ,
  • the band has a slightly stepped rectangular cross-section.
  • the representation is not to scale.
  • Each of the two side surfaces is divided into a strip-shaped partial surface 1.1 and an adjoining and set back by a few tenths of a millimeter or deeper partial surface 1.2.
  • On each of the faces 1.1 is a very thin layer of adhesive 50, which has a very high adhesiveness and after peeling off the already mentioned protective films 1a, 1b strongly adheres to glass.
  • the faces 1.1 and 1.2 can, as shown, be about the same width.
  • the strip 1.1 may be narrower in favor of a larger width of the strip 1.2.
  • the illustrated, stepped rectangular cross section is exemplary.
  • the band can also do the in FIG. 2a shown, double stepped or grooved cross section, wherein the groove may be formed instead of the illustrated rectangular cross section as a groove.
  • FIG. 2b slightly trapezoidal cross-section.
  • FIG. 3 schematically shows the arranged in the coating station 10 nozzles 11 and 12 for applying the butyl adhesive to the deeper strip-shaped faces of the side surfaces of the belt 1.
  • the flow of the butyl adhesive through each of the nozzles 11 and 12 is controlled by means of actuators driven slide 11.1 and 12.1 in such a way that the side surfaces of the belt 1, each with an adhesive layer 60 substantially constant, ie independent of the instantaneous speed of the belt 1 thickness are coated ,
  • the drive motors of the slide 11.1 and 12.1 and optionally downstream thickness gauge devices are connected to the machine control (not shown).
  • the nozzles are displaceable to adapt the distance of their mouths to bands of different widths according to the double arrows.
  • roller pairs downstream of the coating station 10, such as 6 and 7 in FIG. 1 provided for lateral guidance of the belt 1 with a wedge-shaped profiled tread so that the illustrated rollers 6.1 and 6.2 touch the tape only at the edges of the belt side surfaces.
  • the rollers, such as rollers 6.1 and 6.2 may be freewheeling or seated on the shafts of unillustrated drive motors which maintain the peripheral speed of the rollers synchronously and in accordance with the instantaneous or instantaneous tape travel speed.
