Definitions

  • the invention relates to a method having the features of the introductory part of claim 1 and a device having the features of the introductory part of claim 11.
  • WO 2016/ 062601 Al From WO 2016/ 062601 Al (EP 3 209 842 Bl ) a method for forming a closed, frame-shaped spacer for an insulating glass pane by applying a pasty and subsequently solidifying strand is known.
  • the thickness of the strand should increase at the beginning and decrease complementarily at the end of the strand.
  • the plastic strand which forms the spacer is treated by subjecting one side of the strand to mechanical vibrations. These vibrations are intended to make the position of the interface between the beginning and end of the strand on the side surface that delimits the interior of the insulating glass pane after it has been assembled no longer clearly visible.
  • the generation and transmission of such vibrations is not only complex, but can also lead to the glass panes of the insulating glass pane breaking.
  • DE 44 33 749 A1 From DE 44 33 749 A1 it is known to form the ends of a strand of deformable material applied to a pane of glass, which serves as a spacer in insulating glass, in a wedge-shaped manner at the joint.
  • the wedge-shaped ends of the strand forming the spacer overlap each other at the joint.
  • DE 44 33 749 A1 does not teach any process steps to avoid air inclusions that arise in the area of the joint.
  • KR 20210085350 A and KR 20210085351 A show spacers made of deformable material, whereby the opposite wedge-shaped ends of the strand forming the spacer for insulating glass are arranged in the area of a corner at the joint. Special measures to avoid air inclusions in the area of the joint are not disclosed.
  • EP 2 878 233 A1 discloses a pane composite comprising two panes which are connected to one another by a hardening adhesive arranged between the panes.
  • WO 97/06332 A2 discloses a thermally insulating spacer for insulating glass panes. The spacer comprises a foamed insulating body and a secondary insulating material. However, WO 97/06332 A2 does not disclose any information on how the ends of the spacer can be tightly connected to one another.
  • Air inclusions between a spacer and a pane of glass placed on it also have the disadvantageous effect of reducing the size of the area with which the spacer rests on the pane of glass and thus the adhesive force between the pane of glass and the spacer.
  • the invention is based on the object of specifying a method and a device with which air inclusions in the area of the joint of a spacer can be eliminated.
  • the free edges of the strand forming the spacer are the lateral edges of the surface of the strand facing away from the glass pane to which the strand has been applied as a spacer, i.e. it is not covered but lies exposed. It is preferred if the depressions produced according to the invention are provided on both side surfaces of the strand forming the spacer that are perpendicular to the plane of the glass pane, which can be done simply by providing two projecting, longitudinal ribs on the side of the active surface of a pressure stamp that can be inserted between jaws placed on the side surfaces of the strand.
  • the formation of air inclusions between the strand forming the spacer and the glass pane placed on the free surface of the strand is particularly reliably prevented if, according to a preferred embodiment, the free surface of the strand is deformed during pressing of the joint so that it is convexly curved.
  • Fig. 1 a glass pane with spacer applied to it
  • Fig. 2a the first end of a spacer at the beginning of the application
  • Fig. 2b shows a side view of the first end of a spacer
  • Fig. 3 shows the second end of the applied spacer
  • Fig. 4 shows an oblique view of a device at a corner of a spacer
  • Fig. 5 shows an oblique view of a device in a straight section of a spacer
  • Fig. 6 shows an oblique view of a device according to the invention
  • Fig. 7 shows a section through the device according to the invention according to Fig.
  • Fig. 8 shows a partial section through a pressure stamp of the device according to the invention
  • Fig. 9 to 11 schematically show the method according to the prior art
  • Fig. 12 to 14 schematically show steps of the method according to the invention.
  • Fig. 1 shows a view of a glass pane 2 on which a spacer 1 has been applied at a distance from the outer edge of the glass pane 2.
  • the spacer 1 consists of a strand 3 made of deformable material, in particular of thermoplastic.
  • Fig. 2a shows the beginning of the application of a spacer 1 to a glass pane 2, whereby the strand 3, which forms the spacer 1, is applied starting at a corner.
  • the first end 4 of the strand forming the spacer 1 is formed in a wedge-shaped, thickening manner.
  • Fig. 3 shows that the second end 5 of the strand 3 forming the spacer 1 is applied over the first, wedge-shaped, thickening end 4, wherein this end 5 is formed in a wedge-shaped tapering manner - complementary to the end 4.
  • a device 10 which, in the embodiment shown in Fig. 4, has an angled, outer jaw 11 and an angled, inner jaw 12.
  • An angled pressure stamp 13 is provided between the jaws 11 and 12 and can be inserted between the jaws 11 and 12, so that the pressure stamp 13 is pressed against the free surface 15 (which is surrounded by the glass pane) 2 ) of the strand 3 and can act on the strand 3 with its effective surface 16 .
  • Fig. 4 shows that the angled outer jaw 11 is applied to the outer side surface 14a of the strand 3, which is perpendicular to the plane of the glass pane 2.
  • the angled inner jaw 12 is applied to the inner side surface 14b of the strand 3, which is perpendicular to the glass pane 2.
  • the pressure stamp 13 of the device 10 is shown in Fig . 4 inserted between the jaws 11 and 12 and has two legs 21 and 22 , between which a curved region 18 is present.
  • the joint 7 is provided in a straight area of the spacer 1.
  • jaws rest from both sides on the side surfaces 14a and 14b of the strand 3 forming the spacer 1.
  • the pressure stamp that can be inserted between the straight jaws is not shown in Fig. 5.
  • Fig. 6 shows an embodiment of the device 10 in which the outer jaw 11 and the inner jaw 12 are formed by bodies 19 and 20 which each have surfaces at an angle to one another which are applied to the side surfaces 14a and 14b of the strand 3.
  • Fig. 6 also shows that there is a curved transition surface between the surfaces that are in contact with the strand 3, the curvature of which is selected to correspond to the curvature of the strand 3 in the corner area.
  • the transition surface between the surfaces of the outer body 19 (jaw 11) that are to be applied to the strand 3 is concavely curved, whereas the transition surface between the surfaces of the inner body 20 (jaw 12) that are to be applied to the strand 3 is convexly curved.
  • Fig. 6 also shows that the pressure stamp 13, which has two legs 21, 22 connected to each other via a curved region 18, is inserted between the bodies 19 and 20 (arrow 25).
  • Fig. 6 shows the situation when the pressure stamp 13 is inserted, and that the pressure stamp 13 has two protruding, longitudinal ribs 17 as projections on its active surface 16 (see also Fig. 8).
  • the ribs 17 are provided on the outer longitudinal edges of the active surface 16 of the pressure stamp 13.
  • Fig. 8 shows that the effective surface 16 of the pressure stamp 13 located between the ribs 17 is concavely curved. Due to the concavely curved effective surface 16, the free surface 15 of the strand 3 forming the spacer 1 is deformed when the ends 4 and 5 are pressed together in the region of the joint 7 so that it is convexly curved (cf. Fig. 12 and Fig. 13).
  • the pressure stamp 13 or at least the part of the pressure stamp 13 having the active surface 16 and the ribs 17 of the pressure stamp 13 are made of a material (for example a silicone) to which the material of which the strand 3 is made does not adhere. It is also possible to cover the active surface 16 and the inner sides of the ribs 17 of the pressure stamp 13 with a coating with anti-stick properties, for example with a coating made of a silicone, or to spray them with an anti-stick agent.
  • a material for example a silicone
  • two depressions 9 are formed in the area of the free edges 8 of the strand 3, as shown in Fig. 12 and in Fig. 13.
  • the depressions 9 extend into the side surfaces 14a and 14b of the strand 3.
  • the depressions 9 are also open towards the surface 15 of the strand 3 facing away from the glass pane 2.
  • the described procedure of the method according to the invention is used, for example, in the production of insulating glass panes (double-pane or multi-pane insulating glass) when a spacer made from a strand of deformable material has been applied to a first (or a further) glass pane of the insulating glass pane to be produced.
  • the use of the method and the device according to the invention ensures that there are no air inclusions in the area of the joint between the ends of the strand 3 forming the spacer 1 after the insulating glass blank has been pressed to its desired size. This is because when the insulating glass blank is pressed in the area of the joint 7, air can escape via the depressions 9 produced according to the invention.
  • the device according to the invention can also be used in a system for producing insulating glass.
  • lateral depressions 9 are formed in the strand 3 by ribs 17 which are provided on the effective surface 16 of a pressure stamp 13. Air can escape through the depressions 9 in the area of the joint 7 when a package of glass panes 2 and 23 and spacer 1 containing the spacer 1 with depressions 9 is pressed into an insulating glass blank. This procedure and the device provided for this purpose is used particularly in the manufacture of insulating glass panes.

Abstract

Lors du raccordement des extrémités qui sont situées l'une au-dessus de l'autre au niveau d'un joint (7) d'un brin (3) qui forme un intercalaire (1) pour verre isolant, des nervures (17) qui sont disposées sur la surface efficace (16) d'un vérin de pression (13) forment des évidements latéraux (9) dans le brin (3). De l'air dans la région du joint (7) peut s'échapper à travers les évidements (9) lorsqu'un ensemble, contenant l'intercalaire (1) avec des évidements (9), constitué de vitres (2 et 23) et de l'intercalaire (1) est pressé conjointement pour former une ébauche de verre isolant. Ce procédé, et le dispositif associé, sont utilisés notamment dans la fabrication de vitres isolantes.
