Definitions

  • the invention relates to a method for assembling insulating glass panes, the interior of which is filled with a gas other than air between pairs of glass plates which are spaced apart and glued to one another along their edges by a frame-shaped, metallic or plastic spacer.
  • a gas other than air between pairs of glass plates which are spaced apart and glued to one another along their edges by a frame-shaped, metallic or plastic spacer.
  • Such a spacer usually consists of a hollow profile rod, which is perforated on its side facing the inside of the pane and filled with a granular desiccant, which serves to bind moisture present in the interior of the pane.
  • either the pierced leg of the spacer must remain free of the desiccant, which has the disadvantage that the amount of moisture that can be adsorbed is reduced or it has to be the bore to the adjacent cavity of the spacer hollow profile are sealed, for example by inserting a sleeve into the spacer or by pressing the outer wall of the spacer holder against the wall facing the inside of the pane.
  • the indentation must take place in such a way that the two flanks of the spacer remain exactly flat, since they have to be glued to the two flat glass plates.
  • they are coated in the usual way with an adhesive, in particular with a polyisobutylene.
  • a filling probe is introduced into one of the bores of the spacer, through which the heavy gas is filled into the interior of the pane, and at the same time a suction probe is inserted into the second bore of the spacer (DE 31 17 259 C1, DE 31 17 256 C2), or a suction head is placed on the spacer in the area of the second hole.
  • the insulating glass pane is thus filled with the heavy gas at a first point and at the same time air and subsequently an air / heavy gas mixture is sucked out at a second point which is as far away as possible through another hole in the spacer until the insulating glass pane is out is sufficiently filled with heavy gas, which can be controlled by a sensor sensitive to oxygen, which can be introduced through a third hole in the spacer into the interior of the pane or into the gas stream extracted from the second hole.
  • the assembly of the insulating glass pane and the filling with heavy gas are preferably carried out when the pane is stationary, the hole for filling the pane preferably being as deep as possible and the hole for suctioning as high as possible.
  • the heavy gas filled in below can gradually push the air in the insulating glass pane upwards, whereby greater heavy gas losses can be avoided if the filling process is carried out with a sufficiently low inflow speed of the heavy gas. Then, however, filling with heavy gas is by far the slowest process step within an insulating glass production line, so that its output, when working with heavy gas filling, is considerably reduced in comparison with an insulating glass production line working without heavy gas filling. To counter this, it has been proposed in DE-GM 87 15 749 to allow the heavy gas to flow into the insulating glass pane at high speed.
  • DE-GM 87 15 749 proposes a super-heavy precision surface press, which clamps the insulating glass panes flush with the surface during filling with heavy gas, so that the glass plates and the spacer cannot bulge. A very complex device for filling with heavy gas is therefore required.
  • the present invention has for its object to show how you can fill insulating glass panes quickly and with less effort than before with heavy gas.
  • a slit-shaped approach can be achieved by first gluing the glass plates together along one of their edges and, for this purpose, not arranging them exactly parallel to one another, but including a small acute angle, so that the space between the glass plates is shaped like a flat wedge Has. The angle does not have to be greater than that an approximately 2 mm wide access is obtained at the edge of the glass plates opposite the apex of the angle. A heavy gas can then flow into the wedge-shaped intermediate space, the access to the interior being expediently largely covered to reduce gas losses.
  • a gap-shaped access is preferably achieved, however, by elastically bending a glass plate.
  • a glass plate which is flat in the state without the action of external forces is elastically bent in accordance with the invention in such a way that its edges lie only in sections in a common plane. This way you have when the glass plates with the spacer between them are collapsed and as long as at least one glass plate is bent, a narrow access to the interior between the glass plates so that it can be filled with a gas. If one bends the glass plates, it can easily be achieved that the access for the various glass plate formats occurring in the practice of insulating glass production is approximately the same size, which is very advantageous for the practical implementation of the method.
  • Advantages of bending the glass plate (s) over the initially acute-angled joining of two glass plates are furthermore that the interior of the insulating glass pane is already largely closed by the spacer without further measures, so that gas losses when introducing the gas can be avoided more easily.
  • the spacer does not have to be modified compared to a spacer for insulating glass panes that are not filled with a special gas, so that, on the other hand, no further operations have to be carried out on the spacer. In particular, it is not necessary to drill through the spacer at two or three points and to seal it again. All work on the spacer that occurs in this connection in the known method is avoided in the method according to the invention. In addition, the spacer is not weakened by any holes.
  • a gas slowly flowing in on a wide front can progressively displace the air from the space between the two glass plates, especially if - as preferred - the glass plate is bent so that two access gaps are formed, which are located on opposite edge sections of the insulating glass pane lie. If the gas is allowed to flow in broadly through one of these gaps, the gas pushes the air in front of it without mixing with it to any great extent and displaces it outwards through the opposite gap, the displacement being assisted by suction can be.
  • the gas losses which result from gas mixed with air flowing out of one gap again can be kept considerably lower in the method according to the invention than in the known method.
  • gas losses can be kept lower, it is rather possible to use such gases for the filling, in which particularly low gas losses are important due to the price or because of the risk of a possible workload.
  • the spacer does not have to be drilled through, it can be wrapped around, i.e. in all of his thighs, be filled with a granular desiccant.
  • the insulating glass pane can be closed very easily according to the invention, namely in that the glass plate, which is not yet fully in contact with the spacer, is now brought into contact with the spacer . If the glass plates were at an acute angle to each other during the filling process, you only have to swivel one glass plate against the other.
  • the insulating glass pane can be closed particularly elegantly if a glass plate is elastically bent by the forces that the glass plate has in its curved shape ten, degrades.
  • the curved glass plate then automatically returns to its original shape due to its elasticity, ie it springs against the spacer and thereby closes the space between the glass plates extremely quickly, so that the gas filled has practically no opportunity to close again after the end of the filling process escape.
  • This is different in the known method, since there inevitably elapses a long time between the end of the filling process and the closing of the bores.
  • the method according to the invention can be carried out in a conventional insulating glass production line, which only has to be modified in the area of the assembly station with relatively little effort. If a gap for filling the gas is to be formed by an acute-angled arrangement of the glass plates, it is only necessary in the assembly station, which is equipped with two mutually opposite, variable-spaced press plates, one of the existing press plates, preferably designed as suction plates for holding a glass plate correspondingly small angle to pivot.
  • insulating glass panes with heavy gas filling and air filling can be produced in any order.
  • the glass plate is preferably bent before it is connected to the spacer, so that it is not important for creating access to the interior of the insulating glass pane, whether and to what extent the respective spacer can be bent.
  • This procedure is particularly recommended for the production of insulating glass glued to the edge, which is produced with the aid of spacers which consist of metallic hollow profile bars and are provided on their two flanks with an adhesive, with the aid of which they glue the two glass plates together.
  • the respective glass plate in such a way that its outer surface is convex, in particular in such a way that it is bent at two opposite edge sections, while the other edge sections between them essentially retain their original shape, that is to say lie in one plane in the case of flat glass plates.
  • the glass plate is bulged, which is similar to a barrel vault, and on both sides of the bulge there are non-bent edge sections with which a corresponding section-wise contact is made with the spacer, so that the space between the two glass plates apart from two gaps opposite one another is closed, the shape of which resembles the cross section of a plano-convex lens.
  • the insulating glass pane In principle, one could fill the insulating glass pane horizontally, with one of the glass plates lying on a table and the second one arranged above it, for example held by a suction device, but the insulating glass pane is preferably filled upright, with it being preferred that the two gaps between the curved glass plate and the spacer are on top of each other.
  • a heavy gas it is expediently filled in through the lower gap and allowed to rise in the space between the two glass plates, displacing the air from the space through the upper gap.
  • both options are less favorable than the preferred procedure, according to which the respective glass plate is bent by being sucked into one or more partial areas of its outer surface and at the same time exerting forces opposite to these partial areas of the suction force on its outer surface.
  • the glass sheet can be bent easily and independently of the position simply by attacking its outer surface.
  • a wall can be provided which, for working with flat glass plates, expediently for the most part has a flat surface and a strip-shaped recess or gap, which is preferably approximately 30 cm wide.
  • a wall with a recess is also viewed as two walls arranged at a corresponding distance from one another. The aim is for the strip-shaped recess or gap in which the suction cups are arranged to be used in the central region of the glass sheet to be bent, if possible.
  • the suction cups are preferably arranged directly adjacent to one another and can be activated individually in order to be able to apply the suction force for bending in an optimal manner and adapted to the size of the respective glass plate.
  • the walls are preferably provided with a number of bores distributed over their surface, through which air can optionally be blown or sucked in. You blow to transport the glass plates along the respective wall. Air through these holes and thereby creates an air cushion between it and the glass plate. To hold the glass plate before and during the bending process, air is sucked in through these holes and thereby the glass plate is sucked against the wall, whereby it advantageously lies flatter when bent than without such a suction.
  • the holder for the glass plate to be bent does not have to be an air cushion wall.
  • For lying glass plates it could be a roller table that has suction cups that can be raised and lowered for bending.
  • the bracket could also be a frame with brackets that grip the edge of the glass plate.
  • the holder could also be an arrangement of suction cups, the front sides of which define a common surface in which the outside of the sucked-in glass plate lies and up to which further suction cups can be pushed.
  • a nozzle with a correspondingly elongated mouth is advantageously used for filling the gas on the edge of the glass plates or on the edge of a glass plate and on the spacer (claims 38 and 39) so that maximum efficiency is achieved.
  • Such an elongated nozzle can also be used to extract the gas-air mixture.
  • a nozzle with an elongated mouth for supplying the gas is that it can be divided into several sections in which guide elements for fanning out the gas flow in different outflow directions are provided. This also opens up the possibility of separately feeding these sections with the gas by means of separate feed lines and thereby optimally adapting the filling process to the respective glass plate format.
  • a further possibility for adaptation results from the fact that the guide elements are interchangeably arranged in the nozzle.
  • Another advantageous possibility is to provide in the device for supplying the gas a plurality of nozzles with different outflow directions, which have separate feed lines for the gas and can be supplied independently of one another.
  • two such nozzles are provided in a V-shaped arrangement and, in addition, a third nozzle (hereinafter referred to as the main nozzle), the outflow direction of which lies between the outflow directions of the V-shaped nozzles and whose mouth is preferably longer than the mouth of the V-shaped arrangement Nozzles, ideally chosen as long as the access to the interior of the insulating glass pane.
  • the gas is preferably introduced at the beginning in a very small amount per unit of time, because it then flows particularly readily along the lower edge of the interior of the pane and reaches the two lower corners;
  • the gas throughput is then gradually increased, preferably linearly.
  • the V-shaped nozzles are closed again after a brief opening and the main nozzle is opened again, which through the Rotary flow displaced air upward through the gap from the upper corners.
  • the filling process is ended when a measuring probe indicates that the oxygen content in the exiting gas stream falls below a predetermined limit value.
  • the mouth of the device for introducing the gas is preferably surrounded by seals which are intended for contact with the glass panels and / or with the spacer.
  • seals are the subject of claims 43 to 45.
  • a nozzle is used to extract the gas-air mixture, then it is best to be opposite the device for introducing the gas, and above it when working with upright glass plates.
  • the suction nozzle must then be adjustable in distance from the horizontal conveyor. For this purpose, it is expedient to provide them on a sled.
  • the suction nozzle is preferably not fixedly arranged on the slide, but rather is connected to the slide by means of a four-bar linkage. This makes it possible to move the suction nozzle at a distance from the walls and suction cups of the assembly station by arranging a lever of the four-way link so that it hits the glass plate rather than the suction nozzle.
  • the sled is then distorted and the suction nozzle is pulled towards the wall.

Air emerging from the gap 74 can therefore not flow upward unhindered, but is deflected to the side and must flow to the right and left edge of the cover element 70 before it is released. This obstruction of the air outlet favorably favors the formation of a cross flow in the interior of the pane.
  • a narrow line 75 is integrated into the cover element 70, through which a small part of the air or air / gas mixture emerging from the gap 74 can be sucked off and fed to a sensor which measures the oxygen content and thus enables a statement as to how large the residual air content in the disc is still.
  • the device shown in FIGS. 22 and 23 corresponds in numerous elements to the device shown in FIGS. 1 to 4, so that in this respect the description there can be referenced.
  • the device shown in FIGS. 22 and 23 differs from the device shown in FIGS. 1 to 4 in that no glass plate is bent in it. Accordingly, the suction cups 21 are missing and instead of two walls 15 and 16 separated by a gap 20, the support wall 6 is only opposite a wall 15 which is designed as an air cushion wall and which is about an axis 76 which, in the plan view according to FIG. 23, at the right end of the wall 15 is arranged and extends parallel to the front of the wall 15 in a vertical plane, is pivotable by a small angle. In addition, the wall 15 can be moved parallel to the support wall 6 as described with reference to FIG. 1.
  • the device works as follows:
  • a glass plate 40 is conveyed up on the rollers 3, positioned against the stop 27, sucked in from the air cushion wall 15 and lifted off the support wall 6 by parallel displacement of the air cushion wall 15.
  • a further glass plate 42 covered with a spacer 41 is conveyed up on the rollers 3 and positioned against the stop 27.
  • the air cushion wall 15 is pivoted about the axis 76 by a small angle, so that there is an acute angle between the support wall 6 and the wall 15. Then the wall 15 is approximated by parallel displacement of the support wall 6 until the glass plate 40 reaches the right leg of the spacer 41 in the plan view according to FIG. 23.
  • the upper and lower wedge-shaped gaps can be covered, for example by a strip covered with foam rubber or by a high-strength, flexible, inflatable tube 77 or 78, which are displaceable.
  • the gap on the left edge of the insulating glass pane is covered in the lower region by a device 31 for supplying the gas, which is introduced at the bottom into the interior of the insulating glass pane and displaces the air from an above, uncovered section of the opening gap.
  • the wall is pivoted against the support wall 6 until it is parallel. This closes the insulating glass pane; it can be removed standing on the rollers 3 after moving the wall 15 back.

Abstract

L'un des panneaux de verre (40) constituant la vitre isolante n'est que partiellement relié à l'autre panneau de verre (42) avant l'assemblage final, en particulier du fait qu'il est recourbé de manière à former momentanément entre le panneau de verre (40) et l'écarteur (41) une ouverture en forme de fente par laquelle on peut introduire le gaz lourd dans l'espace intérieur de la vitre d'isolation.
