Definitions

  • the invention is based on a method having the features specified in the preamble of patent claim 1 and of a device having the features specified in the preamble of claim 20.
  • a method and an apparatus for carrying out such a method are known from EP 0 674 086 A1 known.
  • gaskets are arranged which are effective between the press plates and extend down to the upper run of the belt which closes down the space between the two glass sheets which stand on top of it. From below a heavy gas is introduced into the chamber, which is bounded by the belt, the glass sheets, the two pressing plates and the vertical seals acting between them. The heavy gas rises in this chamber and its supply is stopped when a certain degree of filling is reached. Then one of the press plates of the other press plate is approximated to close the insulating glass pane.
  • the heavy gas is supplied either through openings in the Iotrevier seals or through the belt serving as a conveyor member. Both are disadvantageous. When feeding the heavy gas through openings in the vertical seals you need moving, coupled to the movable seals Gäszu slaughter classroom adopted, which requires some equipment and complicated the construction of the seals. Moreover, as heavy gas is introduced through openings in the vertical gaskets located at the front and rear edges of the two glass panels, it is difficult to evenly displace the air between the glass panels, the more difficult the longer the glass panels are. The introduction of heavy gas through the belt is disadvantageous because it is contrary to the main task of the belt to convey the glass sheets and close the gap between the glass sheets down.
  • the EP 0 674 086 A1 does not disclose a feasible way to deliver the heavy gas through a unitary belt. Described is the ability to arrange two straps spaced apart on a channel having upwardly directed openings located between the two straps. Through the channel supplied heavy gas can then rise through the openings between the belt in the space between the glass sheets.
  • the disadvantage here is that two separate belts are sealed and that the horizontal conveyor must be designed to be transversely displaceable for adaptation to different thickness glass panels and different thickness of insulating glass panes.
  • the present invention has for its object to provide a way how insulating glass panes between two plates of a vertical assembly device for insulating glass panes can be filled with less effort evenly and with high degree of filling with a gas other than air and then closed.
  • the insulating glass panes are not horizontally filled with a gas other than air and assembled, but in a vertical or inclined position so that the gas other than air, in particular a heavy gas, which is specifically heavier than air, for example argon, in the lower region be supplied to the insulating glass to be formed and displace the air initially located between the glass panels upwards.
  • a heavy gas which is specifically heavier than air, for example argon
  • Production lines for insulating glass panes in which the glass sheets from which the insulating glass panes are assembled, standing and against a tilted support means from one station of the production line to the next station of the Production line are generally referred to as "vertical" Fertigüngslinien.

  • the last option given is preferred. It is best to position a pair of glass sheets at one of the ends of the sheets and place one of the movable seals against these ends of the sheets. The other movable seal can be moved between the plates in the conveying direction of the belt to next to the rising edges of the glass panels.
  • the glass sheets are to face each other during gas filling so that they can be connected by closing the glass sheets, in particular by approaching the plates of the apparatus for gas filling and assembling of insulating glass panes, to form a closed insulating glass pane.
  • the glass sheets are already congruent and parallel to one another during gas filling.
  • the gap between the belt and the one glass sheet through which the gas other than air is filled can be made in different ways.
  • One option is to lift the glass sheet off the belt.
  • Another way to provide a distance between the lower edge of the glass sheet and the belt, is to pivot the belt about an axis parallel to the conveying direction, with a pivoting angle of a few degrees sufficient.
  • the plates are usually provided with holes through which air can optionally be blown or sucked.
  • air By blowing is between the plate and a glass plate leaning against it produces an air cushion on which it can slide gently during transport.
  • a glass sheet For fixing a glass sheet to such a plate, it is sucked.
  • the glass sheet can first be sucked from its plate and then lifted by briefly lifting the plate, which can be done with pressure cylinders.
  • either the first glass sheet or the second glass plate provided with a spacer can be brought with its lower edge at a distance from the belt. Preferably, this is done with the first glass sheet on which there is no spacer.
  • the gas can then flow by the shortest route, immediately behind the edge of the first glass sheet in the space between the glass panels and finds for this in all possible insulating glass pane thicknesses approximately the same conditions.
  • an elongated nozzle can be pushed into the gap between the belt and the edge of the first glass sheet spaced therefrom, from the side.
  • a plurality of individually shut-off nozzles can be provided one behind the other in the conveying direction. This has the advantage that the length of the nozzle arrangement can be matched to the length of the insulating glass pane.
  • an elongate nozzle or an elongated arrangement of individually lockable nozzles attaches to the underside of the plate at which the glass plate removed from the belt during gas filling is arranged, especially the first glass pane.
  • the supply device for the gas is then without one of it separate Zustellterrorism required, in all possible insulating glass formats always at the point at which the gas can enter into the space between the glass panels.
  • both plates can be movable.

  • the seal on the side of the second glass sheet can be supplemented by the fact that the belt in its filling position also bears tightly against the lower edge of the first plate of the device, which for this purpose preferably bears a seal extending in the conveying direction at its lower edge which may be an elastomeric tread, in particular a hollow profile, on which the belt or a belt supporting strip meets when it is pivoted to its filling position.
