Definitions

  • the invention is based on a method for assembling insulating glass panes with frame-shaped spacers from a plastic mass by conveying the glass panels in an almost vertical position, by continuously applying the initially pasty mass in the form of a strand to a first glass panel along its edges, whereby the frame-shaped spacer is formed, and joining the first glass sheet with a second glass sheet so that the spacer adheres to both glass sheets, the second glass sheet being positioned opposite one another in the almost vertical position of the first glass sheet before being joined. Furthermore, the invention is based on a device with the features specified in the preamble of claim 8.
  • insulating glass panes which consist of glass panels, which are glued to one another at the edge with the interposition of a frame-shaped spacer, have been assembled in an almost vertical position in order to add a sag of the upper glass panel which is otherwise observed in a horizontal position during assembly avoid. Such a sag cannot occur after assembly of the insulating glass pane, if the interior of the insulating glass pane is thereby hermetically sealed. more undone.
  • plastic spacers When plastic spacers are used, there is also the fact that they can flow under the weight of a glass sheet bearing on them, especially in the case of large-format and thick glass sheets, and when the plastic spacer is only immediately before the insulating glass pane is assembled by extrusion onto one of the glass sheets is applied, so that it is difficult in this way to produce spacers with a precisely predetermined thickness, ie insulating glass panes with a precisely predetermined air gap.
  • this is an additional work step which is undesirable per se and makes production more expensive.
  • the present invention has for its object to show a way how to do insulating glass panes with a plastic spacer, which is not prefabricated, but extruded onto one of its glass sheets as a strand immediately before the assembly of an insulating glass pane, can assemble even particularly wide spacer strands with a precisely predetermined spacing of the glass sheets from one another and without sagging.
  • the combination of features according to the invention combines the advantages of a vertical insulating glass assembly line with the advantages of a horizontal method of operation without having to accept their respective disadvantages. Only for the purpose of applying a plastic spacer by extrusion onto a glass sheet does the vertical mode of operation differ, in that only one of the glass sheets, namely the one on which the plastic spacer is to be extruded, is brought into a horizontal position before extrusion and after extrusion is brought back into its vertical or almost vertical starting position.
  • the actual assembly takes place in the almost vertical position of the glass panels, in which an undesired glass panel sag is avoided and in which the air intermediate space of the insulating glass pane, ie the width of the spacer f compressed after the glass sheets have been compressed, not by the weight of a glass sheet resting thereon, but solely by the pressing process, which is usually carried out in a plate press with a calibrated plate spacing.
  • the time period in which the spacer is extruded onto a glass sheet is preferably used to position the second glass sheet to be connected at the point at which the actual assembly is to take place. Therefore, the first glass sheet is preferably first conveyed into a station in an almost vertical position, in which it is brought into the horizontal or almost horizontal position and the pasty strand is applied, while the second glass sheet follows the first glass sheet in the almost vertical position, in this position runs through the station into a plate press and is transversely displaced from its infeed path to a position parallel to it.
  • the first glass sheet covered with the initially pasty strand is only then returned to the almost vertical position pivots when the second glass sheet has passed through the station in which the spacer is extruded and released again. Thereafter, the glass sheet covered with the spacer is conveyed on the infeed path into the plate press, positioned there opposite the second glass sheet and joined together, wherein it is calibrated by the plate press to a preselected air gap.
  • the spacer widens due to the compression that occurs. Since the extent of the compression is known, the extent of the widening is also known.
  • the spacer is therefore extruded onto the first glass sheet in such a way that it has a waist between its underside lying on the glass sheet and the surface facing away from it, which is dimensioned such that it is compressed in the press by the subsequent upsetting disappears.
  • Such a mode of operation would not be possible when extruding the spacer onto an approximately vertically standing glass sheet, because the waist would further increase the sagging or tipping of the spacer strand at its horizontal sections.
  • the spacer is therefore preferably extruded onto the glass sheet without gaps, and this measure is combined with one or both glass sheets being bent away from the spacer, in particular at one corner, before they are assembled and pressed to form the insulating glass pane.
  • a press suitable for this purpose is known from WO 89/11021 and from DE-U-9014304 for another purpose, namely for filling a foreign gas into an insulating glass pane.
  • the commonly used polyisobutylene is a thermoplastic.
  • the extruded spacer on the first glass sheet is preferably cooled, for example by being blown with air, the air also being colder than room temperature.
  • the spacer is extruded from a crosslinking plastic
  • the solidification can be promoted by heating it to accelerate the crosslinking, for example by blowing on with hot air or by irradiation with heat radiation, possibly followed by cooling by blowing on with cold Air.

Abstract

L'invention concerne un procédé permettant d'assembler des doubles vitrages au moyen d'une entretoise (7) en forme de cadre, constituée d'une matière plastique, dans une chaîne de fabrication fonctionnant sensiblement dans le plan vertical. Selon ledit procédé, on fait passer une première plaque de verre (6) de sa position initiale sensiblement verticale à une position horizontale. L'entretoise (7) est ensuite extrudée sur la plaque de verre (6). Simultanément, une seconde plaque de verre (26) est conduite, en position sensiblement verticale, à travers le poste de travail (5), jusqu'à un dispositif d'assemblage et d'application de pression (9) où elle est positionnée. La première plaque de verre (6) pourvue de l'entretoise (7) est alors ramenée dans sa position verticale et conduite, dans cette position, jusqu'au dispositif d'assemblage et d'application de pression (9) où elle est accouplée avec la seconde plaque (26) pour former un double vitrage.
