Definitions

  • the invention relates to a method for producing a spacer made of thermoplastic on glass panes in the train the production of insulating glass panes, in the thermoplastic Plastic along the edge of the glass sheet and stranded on the glass pane is sprayed on.
  • thermoplastic materials For spraying thermoplastic materials onto glass panes various embodiments of nozzles are known. From the AT 399 497 B and from US 5 481 276 A nozzles are known which are based on its end facing the glass pane is open and, based on the direction of movement, behind an outlet opening for example formed with a rectangular cross section have thermoplastic material.
  • the invention has for its object, starting from the described State of the art a method for applying spacers made of thermoplastic on glass panes in the course of manufacturing of insulating glass panes to indicate with the sharp-edged Corners can be formed.
  • This problem is solved with a method of the aforementioned Genus in that when spraying a corner in the strand Spacer plastic forming the spacer in one go sprayed onto the glass pane and a sharp-edged inside corner of the Spacer is generated, and that when spraying a corner Spacer-forming plastic on the glass pane without sticking the plastic is sprayed onto the glass pane in the corner area becomes.
  • the method according to the invention also allows it Start and end of a sprayed spacer together connect tightly, with the junction in the area a corner of the spacer is what manufacturing advantages offers and there also results in a sharp-edged inner corner.
  • Nozzle with a hollow nozzle body, on which a line for the Feeding of thermoplastic is connected, and with a nozzle holder, via which the nozzle with a drive for Executing the movements of the nozzle is coupled, and with a
  • This is the outlet opening for the thermoplastic characterized in that from the nozzle housing on both sides of the outlet opening Project legs, one of which serves as a guide surface and the other serves as a guide surface.
  • the method according to the invention can be carried out with the aid of a nozzle 1 be, which has a hollow nozzle body 41 on which a Line 46 connected for the supply of thermoplastic material is. From the nozzle body 41 are on both sides of the Exit opening 6 legs 2 and 3, which are related to the Direction of movement rear-facing outlet opening 6 for thermoplastic Limit plastic.
  • the leg 2 of the nozzle 1 is longer than leg 3. The longer leg 2 serves as the guide surface and the shorter leg 3 as the guide surface.
  • a nozzle 1 as used for carrying out the method according to the invention to apply a thermoplastic spacer a glass pane in the course of producing insulating glass panes can be used, the long guide surface 2 and the short guide surface 3 contrary to that symbolized by an arrow 40 in FIG. 3
  • the nozzle body 41 of the nozzle 1 is after below, that is, on the one of the glass pane on which the spacer is is sprayed on, facing side open and front, i.e. at hers 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 on Spacer made of thermoplastic on his surface facing away from the glass pane is convex, which is Spacer made of thermoplastic is advantageous.
  • the long guide surface protruding from the outlet opening 6 of the nozzle 1 2 and the short guide surface 3 have a height that in The embodiment shown is the same as the height of the spacer to be sprayed on made of thermoplastic material.
  • One opens onto the upper end wall 45 of the nozzle body 41 of the nozzle 1 Line 46 for feeding thermoplastic.
  • the nozzle holder 48 is coupled to a drive, the 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 pane, onto which the spacer is sprayed.
  • the nozzle holder 48 is in the pivot axis 4 arranged the nozzle, which in turn preferably in the area of rear free edge 50 of the guide surface 3 is arranged.
  • the Nozzle holder 48 can also be attached to another part of the nozzle 1, e.g. be attached to the leg serving as the guide surface 3.
  • the nozzle 1 is to be understood schematically.
  • the Shape of the nozzle body 41 of the nozzle 1 deviates from the cuboid shape 3 are chosen so that there are favorable flow conditions the thermoplastic from the feed line 46 result up to the outlet opening 6 of the nozzle 1.
  • the nozzle 1 When a spacer 7 is sprayed onto a glass pane the nozzle 1 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 Strands made of thermoplastic plastic, used as a spacer 7 is to serve, 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 vertical by one to the glass pane onto which the spacer 7 is sprayed, aligned axis 4 pivotable, 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. la.
  • the nozzle 1 When spraying thermoplastic 7 to a spacer 7 on a glass sheet, the nozzle 1 in as usual by moving the nozzle 1 itself and / or the glass pane, on which the thermoplastic to form the Spacer 7 is to be sprayed on, along the edge of the glass pane moves, whereby, as is known per se, the strand at a distance is applied within the outer edge of the glass pane. So there is an edge joint between the two glass panes, which are limited inwards by the spacer 7 is, and can be injected into the sealing compound.
  • the nozzle 1 by moving (arrow 12) the nozzle 1 itself and / or the glass pane comes into the area of a corner 10 to be formed, the nozzle 1 is lifted slightly from the glass pane (in order to prevent the thermoplastic spacer 7 on the glass sheet firmly adheres when it comes out of the nozzle in the area of corner 10 1 is pressed) and then rotated about the pivot axis 4, like this in Fig. La is illustrated by the arrow 11.
  • This moves the inner edge of the free edge of the shorter leg 3 of the Nozzle 1 relative to the previously created section of the spacer 7 not, but remains in place, so that the 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 is in the corner area rounded off as it moves from the one moving along an arc longer leg 2 is defined.
  • a spacer 7 made of thermoplastic Plastic should be injected, can be done as this is schematically illustrated in Fig. 2a to e.
  • Fig. 2a the part of the spacer 7, which is being injected, in full lines, the beginning 20 of the spacer 7, the has been generated at the beginning of the spraying process is by cross hatching highlighted and the corner 10 to be trained (the last one 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 corresponds to the Thickness of the shorter leg 3 of the nozzle 1 is shortened is so that the deflection movement of the nozzle 1 (S arrow 22 according to FIG. 2b) is unnecessary. This is easily possible because it is sufficient Plastic is available to the stripping according to FIG. 2c to 2e with the gap between the beginning and end of the spacer 7 Seal plastic.
  • FIGS. 2a to 2e The nozzle 1 is moved again from position 2b (based on the representation of Fig. 2) after the shorter leg 3 on the outer surface of the beginning 20 of the spacer 7 has been moved past, so that the last section of the last generated leg of the spacer 7 again straight runs as shown in Fig. 2c (see the S arrow 30 in Fig. 2c).
  • the nozzle 1 a longer leg 2, which serves as a guide surface for the thermoplastic Plastic, which is to form the spacer 7, is used, and one has shorter leg 3, which is designed 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 panes thermoplastic from a nozzle in a strand on the Glass panel sprayed on while the nozzle is running along the edge of the Glass pane is moved. If there is a corner in the spacer with the nozzle is to be generated, the nozzle is perpendicular to the glass pane aligned axis pivots, which axis in the area of the inner corner a corner to be created in the spacer. When swiveling the nozzle is slightly lifted off the glass, so that the strand of plastic that is squeezed out of the nozzle does not adhere to the glass pane while the nozzle is being pivoted becomes.
