    The invention relates to a method and a device for sealing insulating glass blanks in the course of the production of insulating glass.
    Insulating glass usually consists of at least two glass panes, which are connected to each other at a distance from each other via a spacer. Spacers are offset inwards relative to the outer edge of the glass panes, resulting in a still open edge joint in the insulating glass blank. This edge joint is filled during sealing with sealant, so that the final bond of the glass sheets is achieved. For the sealing of insulating glass blanks, various methods and devices have become known, which are filled with one or two nozzles, which move along the edge of the insulating glass blank and during their movement along the edge sealant in the outwardly open edge joint.
    The control of sealing devices is complicated, since not only the size of the edge joint, the relative speed between the sealing nozzle and insulating glass blank, but also the temperature and the nature of the material used as a sealing compound are taken into account. Common sealants are masses that cure, with predominantly polysulfide-based masses.
    Also known are so-called hot melt adhesives (hot melt), which are at room temperature in a solid, high molecular weight state. By heating, they are put in the liquid state of aggregation and are able to wet the surfaces to be bonded. Immediately after cooling forces can be transmitted, so it is a solid bond achieved. Hotmelts have the advantage of being 100% solids and containing no solvents, so they do not shrink. It is also known to add additives to hot melt adhesives which permit postcrosslinking. These post-crosslinked hot-melt adhesives, which have been provided with additives, continue to crosslink under the influence of moisture after falling below the melting temperature. Are known hot melt adhesive based on ethylene-vinyl acetate and based on polyester. Furthermore, hot melt adhesives based on polyamide and based on silanes are known.
    The invention has for its object to provide a method of the type mentioned, in which a hot melt adhesive, in particular a reactive hot melt adhesive can be used as sealing compound.
    This object is achieved according to the invention with a device having the features of claim 1.
    Preferred and advantageous embodiments are the subject of the dependent claims.
    As far as the device according to the invention is concerned, the object underlying the invention is achieved with the independent claims directed to the device.
    Preferred and advantageous embodiments of the device according to the invention are the subject of the device claim dependent dependent claims.
    Since in the inventive method, the sealing compound is supplied in the form of hot melt adhesive via a buffer of the sealing nozzle, there are considerable advantages.
    First, fluctuations in conveying the hot melt adhesive used as sealing compound from the barrel are compensated by the barrel pump and there is created after the buffer a constant and uniform flow rate of a uniform filling of the edge joint during sealing of insulating glass blanks guaranteed.
    The buffer also allows to replace an empty barrel with a new (full) barrel without interrupting the sealing process, if this becomes necessary. Thus, the inventive method is suitable to bridge the barrel change and also to ensure an uninterrupted running the Versiegeins of insulating glass blanks. Furthermore, the method according to the invention allows the quantity of sealing compound (hot melt melt) injected at the edge joint to be controlled at constant temperature solely by the size of the nozzle opening (for example by means of a rotary valve) and by means of the pressure with the sealing compound at the nozzle is to be regulated.
    The buffer is formed in a preferred embodiment as a cylinder in which a displaceable piston containing the mass contained in the cylinder (hot-melt adhesive) is received, wherein the piston yields at pressure increases in the sealing compound and is advanced at pressure reductions, so that at the output of the Buffer and thus at the (at least one) sealing nozzle a uniform flow of hot melt adhesive is given, although sealing compound from the barrel pump intermittently (pulsating) is conveyed to the buffer.
    In a preferred embodiment, the intermediate store is designed as a ride-on with the sealing nozzle and in particular as an extruder pressing plant, so that a spatially favorable arrangement results.
    By the embodiment according to the invention with a buffer formed as a hydraulic cylinder {intermediate buffer), a pressure equalization is achieved and ensures an uninterrupted production (sealing).
    As far as the device is concerned, a particularly advantageous mode of operation and a simple construction, when the insulating glass blank is leaning against a roller field, is supported at the bottom by a conveyor belt having a coating on which the hotmelt adhesive used as sealing compound is applied. not liable. For most hot melt adhesives, especially those that are postcrosslinking, a silicone coated conveyor belt is suitable.
    In the conveyor belt, which is preferably divided into a plurality of sections, a portion is provided which is lowered, so that when the lower horizontal edge of the insulating glass blank must be sealed, the sealing nozzle can be applied from below to the insulating glass blank , This embodiment makes it possible to work with a so-called single-nozzle sealing machine which is slidably guided up and down in the machine via a carriage on a guide beam fixedly mounted (machine frame).
    On the carriage over which the sealing nozzle and its associated device parts are displaced up and down, in a preferred embodiment, the intermediate buffer, which is for example designed as a hydraulic cylinder, mounted so that it is moved with the sealing nozzle and only short distances between the intermediate buffer and the sealing nozzle.
    Further details and features of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings. It shows:
    1 is a sealing device in side view,
    Fig. La a detail,
    2 the sealing device from the front,
    3 is an oblique view of the sealing device,
    Fig. 4 is a plan view of the sealing device, and Fig. 5 is another oblique view of the sealing device.
    A sealing device according to the invention comprises a supporting field 2 mounted in a machine frame 1 (" machine frame ") for the insulating glass blank 3 to be sealed.
    The support panel 2 is formed in the embodiment shown as a role field, so includes a panel (wall), in which a plurality of freely rotatable rollers 4 are mounted.
    At the lower edge of the support field 2, a horizontal conveyor 5 is provided, which is divided into a plurality of endless belt sections 6. The conveyor belt of each of the sections 6 is provided with a coating on which the hot-melt used in the sealing device as a sealing compound does not adhere. For most hot melt adhesives, a coating of silicone conveyor belts is suitable.
    Which results in particular from the illustration of Fig. La, just above the horizontal conveyor 5, a series of guide rollers 7 are provided, which provide the same for the exact running of the insulating glass blank 3 during transport and sealing.
    In addition, as shown in Figs. 1 and 1a, at least one suction conveyor is provided with a suction head 8 which is movable parallel to the horizontal conveyor 5 and which takes over the transport of the insulating glass blank 3, during which the upper and lower horizontal edges are sealed. This sucker 8 also ensures that the insulating glass blank 3 remains in the correct position when the vertical edges of the insulating glass blank 3 are sealed.
    As shown in FIG. 1, the support field 2, as usual for vertical systems, by a few degrees, for example 5 degrees, inclined backwards.
    At a distance in front of the supporting field 2, a guide bar 10 is fixedly mounted on which a carriage 11 is guided movable up and down by means of a drive 12. The carriage 11 carries a sealing head 13 with a sealing nozzle 14 and formed as a hydraulic cylinder intermediate buffer 15 for the sealant used.
    The sealing compound is supplied to the intermediate buffer 15 from a drum 16, in which sealing compound (hot-melt adhesive) is contained, by means of a drum pump via lines 17. In addition, because it is hot melt adhesive, the barrel 16 is associated with a heater to heat the hot melt adhesive to the processing temperature.
    In the embodiment shown, the sealing device is as
    A single-nozzle sealing device is formed, so that a single nozzle 14 is provided, which moves off the periphery of the insulating glass blank 3 during sealing. For this purpose, the insulating glass blank 3 is sealed during sealing of the upper and lower horizontal sections of the edge joint by the opening of the edge of the edge joint. * * * * · · Ι · 4 ·· · · ► · * * · »· * · · t • * · - * / - ·· * I · • * ♦ · * * < * * · «Conveyor 5 supported by the suction head 8 at least one suction conveyor moves horizontally, the sealing nozzle 14 is stationary. When sealing the two vertical edges of the insulating glass blank 3 stands still and the sealing nozzle 14 is moved over its carriage 11 up and down to fill the vertical edges with sealing compound (hot-melt).
    It is understood that, as is usual for sealing systems, the sealing nozzle 14 is pivotally mounted on the sealing head 13, so that they can assume the respective correct position relative to the edge joint. In this case, a stepless rotatability be provided when an insulating glass blank 3 is sealed with special shape.
    The intermediate buffer 15 is, as can be seen from the drawings, designed as a hydraulic cylinder, wherein in the cylinder, the piston is slidably received in the cylinder, a space is provided which is acted upon via line 17 from the barrel pump with hot melt adhesive from the drum 16. The piston of the intermediate buffer 15 is acted upon hydraulically (it is preferably acted upon elastically) and so able to compensate (periodic) pressure changes resulting from the operation of the barrel pump, so that from the intermediate buffer 15 of the sealing nozzle 14 sealing compound (hot melt adhesive) without pressure fluctuations is supplied.
    The buffer 15 also allows the
    Sealing seal 14 to apply sealing compound while a barrel 16 is changed.
    This results in not only a uniform work with constant (but adjustable) pressure, but also an uninterrupted working, since the sealing at a
    Cask change does not need to be interrupted.
