Definitions

  • the invention is based on a method with the features specified in the preamble of claim 1.
  • insulating glass panes are stacked vertically on a bearing block and lean against each other. In an appropriate arrangement, they are also transported to the end user. So that the insulating glass panes do not rub against one another with their surfaces and thereby get scratches or even become blind in places, it is necessary to keep them at a distance.
  • glue spacers on one side of each insulating glass pane which are so soft that they cannot scratch an adjacent insulating glass pane.
  • panes made of cork or a foam are used, which are designed to be adhesive on one side and are applied by hand to each pane of insulating glass leaving the insulating glass production line.
  • the adhesive with which the cork and foam discs are equipped is selected so that it can be removed from the glass surface without leaving any residue.
  • the adhesive is only applied on one side to the panes made of cork or foam, so that they always adhere to only one of two adjacent insulating glass panes, which ensures that when the insulating glass panes are moved, the spacers applied to them, but not to the adjacent surface of the adjacent ones Insulating glass pane stick so that the desired protection of the surface remains guaranteed.
  • the invention has for its object to remedy this situation by a method which can be carried out rationally and automatically with any disk formats.
  • Hot melt adhesives are sticky in the molten state, but solid immediately after cooling. Since the hot-melt adhesive is only applied to the insulating glass panes in places and the insulating glass panes themselves are cold, the hot-melt adhesive cools down very quickly and then no longer feels sticky; that is, although it adheres to the insulating glass pane to which it was applied, it cannot adhere to a second insulating glass pane, which is then leaned against it.
  • the cooling and setting of the hot-melt adhesive takes place in a shorter period of time than the cycle time of insulating glass production lines customary today, i.e. that is, the insulating glass panes onto which the hot melt adhesive is sprayed at the end of the production line, as they come, can be removed from the production line and placed one after the other on a pedestal without any
  • Suitable hotmelt adhesives are, in particular, those which do not adhere too firmly to the glass surface, so that they can be removed from the glass surface easily and without residue when cold.
  • a hot melt adhesive for example, which is sold by Bostik GmbH in D-6370 Oberursel under the name Thermogrip 9644, is suitable. It is a hot melt adhesive based on ethylene copolymer with a softening point of 73 ° C (according to Kofler), with a melting point of 95 ° C (according to Kofler) and with a processing temperature between 180 and 220 ° C. This hot melt adhesive was developed for bonding wood, wood fiber and chipboard and other wood materials, i.e.
  • this hot-melt adhesive adheres less well to a smooth, non-porous glass surface and can be removed easily and without residue when cold; however, he is sufficiently liable to do his job as a spacer under the conditions of interest here.
  • Hotmelt adhesives are usually introduced into a melting container in the form of granules, heated to their processing temperature therein, fed to a closable nozzle by means of a pump or by piston pressure, and applied with the latter.
  • the conveying of the hot melt adhesive from the melting tank to the nozzle and the opening and closing of the nozzle itself - unlike the application of adhesive cork or foam discs - can be controlled automatically with little effort.
  • one or more nozzles, which are connected to a melting vessel, are expediently arranged in one
  • sensors that respond to the insulating glass panes and use them to control the opening, closing and moving of the nozzles.
  • insulating glass panes In the case of smaller insulating glass panes, it is sufficient to apply two continuous or interrupted hotmelt adhesive strands to one outer side of the insulating glass pane, best of all parallel to and in the vicinity of two parallel pane edges. In the case of larger insulating glass pane formats, a third continuous or interrupted hot melt adhesive strand is preferably applied, which is best arranged in the middle between the two remaining hot melt adhesive strands. Because an insulating glass pane usually runs through with one of its edges along one and the same predetermined line
  • one of the nozzles can be arranged in a fixed distance from this predetermined line, while the other two nozzles can be arranged so that their distance from the predetermined line depends on the size of the Insulating glass panes is changeable.
  • the specified line is formed by the top of the stand-up conveyor.
  • an almost vertical support device e.g. an air cushion wall or a support roller array
  • the insulating glass panes pass through the last station of the production line in a horizontal position, usually lying on a roller table, then they could with one of their edges are guided along a roller row delimiting the roller table, the rollers of which have vertical axes, and this roller row would then form the predetermined line, with respect to which a nozzle can be arranged in a stationary manner.
  • the hot melt adhesive can be applied in the form of strands which extend over the entire length of the insulating glass panes.
  • the nozzles are preferably operated intermittently, so that there are no continuous, but rather interrupted hot melt adhesive strands which fulfill their task of keeping two insulating glass panes at a distance as well as continuous, uninterrupted strands.
  • the last station in a production line for edge-sealed insulating glass is a sealing station, in which the edge joints of the insulating glass are filled with a sealing compound - usually with a thiokol - and thus protected against the ingress of moisture.
  • the hot-melt adhesive is also expediently sprayed onto the insulating glass panes, preferably simultaneously with the sealing of an edge joint of the insulating glass pane. In this way, the expenditure for the application of the hot-melt adhesive can be kept low, both the expenditure on equipment and the control expenditure; in addition, the cycle time of the production line is not extended by the application of the hot melt adhesive.
  • the device for carrying out the method contains a horizontally conveying conveyor through which the insulating glass panes pass in a predetermined plane parallel to them (the pane running plane).
  • the disc running plane can be formed by a horizontal roller table;
  • modern production lines work with horizontally conveying stand-up conveyors, e.g. B.
  • the device according to the invention has one or more nozzles directed against the plane of the pane for spraying the hot melt adhesive onto the insulating glass pane, and of these nozzles, at least one should be displaceable parallel to the plane of the pane transversely to the conveying direction in order to enable adaptation to different pane formats , wherein the control of the movable nozzles - as already mentioned - is carried out by sensors which respond to the position of the insulating glass panes being conveyed and trigger corresponding control commands.
  • the distance between the nozzles and the pane running plane can preferably be changed to adapt to different insulating glass pane thicknesses.
  • the conveyor - as is customary for production lines in which the insulating glass panes are manufactured upright - has a guideway for one of the edges of the insulating glass pane, in particular a guideway in the form of an erecting conveyor, on which the insulating glass pane stands upright and against one that defines the pane running plane Support wall is leaned promoted, then one expediently arranges one of the nozzles at a constant distance from this guideway, so that it applies hot melt adhesive to the passing insulating glass panes at a constant distance from the edge of the pane guided along the guideway.
  • the second nozzle or any further nozzles that are provided are arranged at a variable distance from this guideway, so that they adapt the further hotmelt adhesive strands close to the edge of the pane away from the guideway and, if appropriate, in the middle between these two, in accordance with the respective insulating glass pane format.
  • two displaceable nozzles are provided, they are expediently driven by a common motor, but via different gears in such a way that the one nozzle is always in the middle between the other displaceable nozzle and the third, non-displaceable nozzle, that is always is shifted at half the speed of the other movable nozzle.
  • the hot melt adhesive strands are applied to the panes in the sealing station of an insulating glass production line, it can be advantageous to arrange one of the movable hot melt adhesive application nozzles and a sealing nozzle on a common carrier that can be displaced parallel to the plane of the pane transverse to the conveying direction, rather than for sealing
  • the edge joints of insulating glass panes also require a displaceable sealing nozzle which can be adapted to changing pane formats and which is also controlled by sensors which respond to the position of the insulating glass panes.
  • the joint arrangement of a hot melt adhesive application nozzle and a sealing nozzle on a carrier can reduce the outlay in terms of apparatus and control.
  • the device has a frame 1, which has a horizontally conveying stand-up conveyor 2 and along the side of the stand-up conveyor a support wall 3, which is designed as an air cushion wall, the flat front side of which is a little (approximately 6 °) from the vertical is inclined at the rear.
  • the support wall is divided into two sections 3a and 3b, and in the space 4 between these two sections, a sealing nozzle 5 can be moved up and down parallel to the front of the support wall 3.
  • the front of the support wall 3 also defines the disc running plane 7.
  • the sealing nozzle 5 is located on a carrier 8, which can be moved up and down on a track 9 by means of a chain drive or a belt drive, which is arranged fixed to the frame parallel to the disc running plane 7 behind the supporting wall 3 .
  • the section of the stand-up conveyor below section 3a of the support wall is a roller conveyor, 2a and the section of the stand-up conveyor below section 3b of the support wall is a chain conveyor 2b made of two oppositely driven, parallel running, endless chains which support supports for the lower disc edges .
  • a second sealing nozzle 6 is arranged for sealing the lower edge joint of the insulating glass panes.
  • the other sealing nozzle 5 is used to seal the remaining three edge joint sections of an insulating glass pane and can therefore be swiveled several times by 90 ° (we refer to the prior art in this regard to DE-PS 28 16 437 and DE-PS 28 46 785).
  • the lowest nozzle 11 is not adjustable in height at a short distance above the roller conveyor 2a (for example at a distance of 10 cm above), while the nozzles 12 and 13 can be moved up and down on a guide rail 15, which is on the right Angle to the conveying direction 10 is arranged parallel to the disk running plane 7 at a distance in front of the support wall 3 and anchored to the frame.
  • the two nozzles 12 and 13 are moved with the aid of chains or toothed belts which are driven by a common motor 16, but the gear ratios for the two nozzles 12 and 13 are chosen differently in such a way that the middle nozzle 12 is always included half the speed of the upper nozzle 13 is moved and always lies in the middle between the two remaining nozzles 11 and 12.
  • the movement of the nozzles 12 and 13 is controlled as a function of the height of the insulating glass panes entering the device.
  • the upper nozzle 13 is expediently brought to a height at which it lies below the upper edge of the insulating glass pane 14 by such a distance that the lower nozzle 11 lies above the roller conveyor 2a.
  • All three nozzles 11, 12 and 13 are connected with flexible pressure hoses 17 insulated against heat losses to a pump 18 which supplies the hot melt adhesive melted in a melting container 19 to the nozzles 11 to 13, which preferably apply the hot melt adhesive intermittently to the insulating glass panes 14.
  • the first opening and the last closing of the nozzles during a pane run is controlled by sensors, not shown, which on the front edge and on the rear edge of each continuous ISO address the glass pane.
  • three parallel hot melt adhesive strands 20 are applied to the continuous insulating glass panes 14, which during the time it takes the insulating glass pane to pass through the device to the end of section 3b. And from there to be converted to a bearing block Cool far enough that they no longer stick to the subsequent insulating glass pane, which is leaned against them on the pedestal.
