Definitions

  • the invention relates to a method for producing a spacer made of thermoplastic material on glass panes in the course the manufacture of insulating glass panes, wherein the thermoplastic Plastic along the edge of the glass pane and strand-like the glass pane is sprayed on, with the characteristics of the introductory one Part of claim 1.
  • insulating glass panes Apart from insulating glass panes, their panes of glass from each other held at a distance by a metallic spacer and There are insulating glass panes with spacers made of thermoplastic material. Usually will It proceeded so that the thermoplastic material, the Spacer is to form, by relative movement of a nozzle along the edge of the glass pane sprayed directly onto the glass pane becomes. Such a procedure is for example from the EP 176 388 A known (Biver method).
  • thermoplastic materials on glass sheets are various embodiments of nozzles known. From the AT 399 497 B and from US 5,481,276 A nozzles are known which their glass pane facing the end are open and, based on the direction of movement, behind an outlet opening for an example formed with rectangular cross-section strand have thermoplastic material.
  • AT 399 497 B shows a nozzle with the features of introductory part of claim 4.
  • the invention is based on the object, starting from the described Prior art, a method for applying spacers made of thermoplastic material on glass sheets in the course of manufacturing Specify by insulating glass panes, with the sharp-edged Corners can be formed.
  • Nozzle One suitable for carrying out the method according to the invention Nozzle has the features of claim 4.
  • Nozzle Preferred and advantageous embodiments of the invention Nozzle are the subject of subclaims 5 to 7.
  • the inventive method can be carried out with the aid of a nozzle 1 be having a hollow nozzle body 41, on which a Line 46 for the supply of thermoplastic material connected is. From the nozzle body 41 are on both sides of the Outlet opening 6 legs 2 and 3 from, which based on the Movement direction rearwardly facing outlet opening 6 for thermoplastic Limit plastic.
  • the leg 2 of the nozzle 1 is longer than the leg 3. The longer leg 2 is used as a guide surface and the shorter leg 3 as a guide surface.
  • a nozzle 1 as used for carrying out the method according to the invention for applying a thermoplastic spacer a glass pane in the course of producing insulating glass panes is usable, stand the long guide surface 2 and the short guide surface 3 opposite to symbolized in Fig. 3 by an arrow 40
  • the nozzle body 41 of the nozzle 1 is after below, so on his glass pane, on which the spacer sprayed, facing side open and forward, i. at her closed in the direction of movement front side by a wall 42.
  • the lower edge 43 of the rear wall 44 in the direction of movement Nozzle body 41 of the nozzle 1 is concave, so that the sprayed Spacer made of thermoplastic material on his surface turned away from the glass sheet is convexly curved, which is for Spacer made of thermoplastic material is advantageous.
  • the projecting from the outlet opening 6 of the nozzle 1, long guide surface 2 and the short guide surface 3 have a height in the shown embodiment is the same size as the height of hopeful mousseenden spacer made of thermoplastic material.
  • a Mounted nozzle holder 48 which is coupled to a drive, for pivoting the nozzle 1 about the axis 4 and for moving the Nozzle in one direction (arrow 49) perpendicular to the plane of the glass sheet, on which the spacer is injected, serves.
  • the nozzle holder 48 is in the pivot axis 4 of the nozzle arranged, which in turn preferably in the range of rear free edge 50 of the guide surface 3 is arranged.
  • the Nozzle holder 48 may also be attached to another part of the nozzle 1, e.g. on the leg serving as a guide surface 3, be attached.
  • FIG. 1 is to be understood schematically.
  • the Shape of the nozzle body 41 of the nozzle 1 different from the cuboid shape of Fig. 3 are chosen so that favorable flow conditions of the thermoplastic material from the supply line 46th until the outlet opening 6 of the nozzle 1 result.
  • the nozzle 1 When spraying a spacer 7 on a glass pane is the nozzle 1 is arranged so that the longer leg 2 of the nozzle 1 as Guide surface on the outer surface of the sprayed onto a glass pane Stands made of thermoplastic material, used as a spacer Serve 7, and the shorter leg 3 as a guide surface on the Inner surface of the spacer 7 comes to rest.
  • the nozzle 1 or in particular its nozzle shoe is perpendicular to one to the glass pane, onto which the spacer 7 is sprayed, aligned axis 4 pivotally, wherein the pivot axis in Area of the end of the shorter leg 3 of the nozzle shoe arranged is, as indicated for example in Fig. 1a.
  • the nozzle 1 When spraying thermoplastic material 7 to a spacer 7 form on a glass, the nozzle 1 in usual way by moving the nozzle 1 itself and / or the glass sheet, on which the thermoplastic material for the formation of the Spreader 7 is mecanicspritzen along the edge of the glass moves, as known, the strand at a distance is applied within the outer edge of the glass sheet. So results in the insulating glass a marginal joint between the two glass panes bounded inwardly by the spacer 7 and can be injected into the sealant.
  • the nozzle 1 When the nozzle 1 by moving (arrow 12) of the nozzle 1 itself and / or the glass pane comes into the area of a trainee corner 10, the nozzle 1 is slightly lifted off the glass sheet (to prevent the thermoplastic spacer 7 on the glass firmly adheres when in the area of the corner 10 from the nozzle 1 is pressed out) and then rotated about the pivot axis 4, as this is illustrated by the arrow 11 in Fig. 1a.
  • This moves the inner edge of the free edge of the shorter leg 3 of the Nozzle 1 relative to the previously generated portion of the spacer 7 not, but remains in place, so that in Fig. 1b shown sharp-edged inner corner 13 in the area of the corner 10 of the Spacer 7 forms.
  • the outer contour 14 in the corner is rounded off as they move from the one along a circular arc, longer leg 2 is defined.
  • the in Fig. 1 has reached dashed line position (pivoting by 90 ° with a rectangular spacer), it will be back placed on the glass, moved on (arrow 15) and the Spraying the next section (leg) of the spacer 7 continued. This ensures that the spacer 7 finally also in the area of a designated corner 10 at the Glass pane adheres.
  • FIGS. 2a to e If the last corner in a spacer 7 made of thermoplastic Plastic should be sprayed, can be proceeded as this is illustrated schematically in FIGS. 2a to e. It is in Fig. 2a, the part of the spacer 7, which is being injected, in plotted with full lines, the beginning of the spacer 7, the has been generated at the beginning of the injection process is by cross-hatching highlighted and the trainee corner 10 (the last Corner) is shown in dashed lines in FIGS. 2a to d.
  • An embodiment of the method of the invention is also conceivable, in which the beginning 20 of the spacer 7 according to the Strength of the shorter leg 3 of the nozzle 1 formed shortened is, so that the deflection movement of the nozzle 1 (S-arrow 22 of FIG. 2b) is dispensable. This is easily possible, since sufficient Plastic is available to when stripping according to the Fig. 2c to 2e the gap between the beginning and end of the spacer 7 with To close plastic.
  • the nozzle 1 is starting from the position 2b again (With reference to the illustration of FIG. 2) offset after the shorter legs 3 on the outer surface of the beginning 20 of the spacer 7 has been moved past, so that the last section of last generated leg of the spacer 7 again straight extends as shown in Fig. 2c (see the S-arrow 30 in FIG Fig. 2c).
  • nozzle 1 a longer leg 2, which serves as a guide surface for the thermoplastic Plastic, which is to form the spacer 7, serves, and a has shorter leg 3, which is formed as a guide surface is.
  • thermoplastic spacer When applying a thermoplastic spacer to a Glass pane in the course of the production of insulating glass is thermoplastic material from a nozzle stranded on the Glazed glass, while the nozzle along the edge of the Glass pane is moved. If with the nozzle a corner in the spacer To generate, the nozzle is one perpendicular to the glass aligned axis pivots, which axis in the region of the inner corner a corner to be created in the spacer. When pivoting the nozzle is lifted slightly from the glass, so that the strand of plastic, which is pressed out of the nozzle, does not adhere to the glass while the nozzle is tilted becomes.
