Description

The invention relates to a device with in the preamble of claim 1 specified characteristics. Such a device is known from EP 0 539 407 B1 known.

EP 0 539 407 B1 discloses a device for assembling insulating glass panes, which are filled with a gas other than air. The device is as a press with two variable in their mutual distance, formed approximately vertically arranged plates, to which two glass panels, from which an insulating glass pane is to be formed, each other can be applied opposite each other. At the bottom of the plate is a horizontal conveyor provided, e.g. from a line of synchronously driven Rolls whose axes are perpendicular to the plates. Around an insulating glass pane Assemble a first glass panel on the rolls of the Horizontal conveyor standing and against the first, fixed, about 6 ° behind Rear inclined plate transported leaned into the device, until Outlet side edge of the plate promoted and flush with the outlet side Edge of the plate stopped. By a lifting device is the first glass panel Little lifted from the horizontal conveyor and then from the second, moving Plate, which is designed as a suction plate, sucked from the first Removed plate and removed from it. A at the outlet side edge of the second plate provided strip of the second plate is formed so that it can be swung away or bent away from the first plate and causes Thus, a corresponding bend of the glass panel, attached to the second panel liable. Then on the horizontal conveyor another, the same size, with a Spacer occupied glass plate promoted, on the first plate dekkungsgleich positioned to the first glass sheet and for this purpose by means of the lifting device lifted off the rollers of the horizontal conveyor. The spacer is coated on both sides with an adhesive. The second plate will be Approximated the first plate until the first glass sheet except its bent Section comes to rest on the spacer. This will create the gap between the two glass panels except for a slit-shaped opening closed along the outlet side edge of the two glass panels. To the Outlet side edge of the two plates is a provided with seals bar placed, which is the vertical section of the edge joint of the still open insulating glass pane closes. The beam is attached to the moving plate and is between the position in which he the outgoing edge of the two Plates rests, and an ineffective position, in which he the insulating glass pane clears the way out of the space between the two plates, movable. In the lower part of the bar is a nozzle for feeding one Heavy gas provided, which through the gap between the first Glass panel and the spacer in the interior of the still open insulating glass pane flows and the air displaces upwards out of the interior. So that Heavy gas does not escape from the wedge-shaped gap at the bottom of the still open Insulating glass is drained and lost is at the beam as a first barrier a cover strip is provided, which is perpendicular to the plane of the plates extending axis against the lower edges of the two plates and the glass panels can be swiveled, which are aligned. The cover strip is provided with a second barrier in the form of a brush whose bristles are inclined are directed upward and at a location where the spacer connection to both glass panels has, up to the spacer in the edge joint between immerse the two glass panels and prevent heavy gas in the lower edge joint can flow along the spacer and is lost.

If the interior of the still-open insulating glass pane the desired amount Heavy gas contains, the bend of the second plate and with it the bend the first glass panel reversed, thereby the interior of the insulating glass pane closed and the insulating glass pane is between the two plates pressed. The press is then opened and the insulating glass pane on the Horizontal conveyor brought out of the press.

The sealing of the vertical edge and the lower horizontal edge of the Insulating glass pane during the filling of heavy gas works in the known Device satisfactory. However, the known device is suitable not for the assembly of insulating glass panes, in which the first Glass panel is larger than the second glass panel. Such insulating glass panes are Stages called. There are stepped discs usual, in which the first Glass panel the second glass panel at least on one side, often on all sides surmounted up to 40 mm. A suitable for stepped discs horizontal conveyor is in EP 0 549 556 A1. However, EP 0 549 556 A1 does not disclose how to make such a step plate in an insulating glass press with heavy gas fill and thereby prevent the heavy gas through a gap at the bottom The edge of the insulating glass can flow out and get lost.

The present invention has for its object to show how in Stepped wheels used in a device for assembling and pressing Insulated glass panes are to be filled with heavy gas prevented can be that through a part of one of the edges of the insulating glass pane extending wedge-shaped gap between the first glass panel and pour out the spacer larger amounts of heavy gas and get lost.

This object is achieved by a device having the in claim 1 specified characteristics. Advantageous developments of the invention are the subject the dependent claims.

The device according to the invention has the well-known from EP 0 539 407 B1 Device for sealing an edge joint, in which a wedge-shaped gap between the spacer and the first glass sheet, a first barrier, which at the marginal joint bounding edges of the two glass panels and / or in the vicinity of the two glass panels to the two plates can be applied, between which the insulating glass pane is assembled and with a Heavy gas is filled. In addition, the invention has a second barrier, which at the starting point or behind the starting point of the wedge-shaped Gap at a location where the spacer rests against both glass panels, until the spacer can be brought into the edge joint, that the second barrier the edge joint divides transversely to its longitudinal direction. The second barrier, however, exists in contrast to the solution disclosed in EP 0 539 407 B1 a brush with obliquely upwards into the edge joint protruding and against the spacer directed bristles, rather, there is the second barrier a plurality of extending parallel to the spacer, individually against a restoring force flexible sections, in particular from a brush. The Bristles or the like flexible sections are so long that the second barrier wider than the distance between the two glass panels. To the second barrier in full width to be able to introduce into the edge joint of the insulating glass pane, it is around a parallel to the plates and perpendicular to the spacer Axle rotatable. From this axis are the bristles or the like flexible sections transversely, preferably at right angles to the axis, from. The second barrier may be in an orientation in which they reach to the two plates runs parallel, inserted into the edge joint and then by turning around her Axis be brought to the plant on the two glass panels. The bristles or The like flexible sections then block the entire cross section between the first, larger glass plate on one side and the opposite one smaller glass panel and the larger glass panel opposite Section of the plate on which the second glass sheet is applied. The single flexible sections, which are preferably the bristles of a flat brush, can steplessly move to different distances both between the two Glass panels as well as between the larger glass panel and the opposite Adjust the plate and thus for different distances from case to case an outflow of heavy gas along the spacer through the edge joint with prevent the wedge-shaped gap. Also a stepless adjustment to different ones Joint depths allows the invention; this is only necessary that the brush is so long that it still has the largest joint depth in practice can cover. If the brush is up against the spacer advanced and then twisted, it is ensured that they are the entire cross section the edge joint can close, by the otherwise heavy gas along the Spacer could drain. This ability of the second barrier to stepless Adapting to different edge joints is important and beneficial because In the current insulating glass production insulating glass panes with different Randfugen usually bun mixed consecutive.

Preferably, the axis is displaceable transversely to the plates in a position in which is closer to the first than to the second glass. The is advantageous when it comes to very small with one and the same barrier Distances between the two glass sheets, e.g. only 6 mm and also very big To be able to seal distances between the glass sheets from 30 mm to 40 mm. If the axis is displaceable transversely to the plates, it is possible to Always place the axle close to the first glass panel and for this purpose to couple with the plate to which the first glass panel can be applied. To this It is ensured that even at very small distances of the glass panels the second barrier introduced into the edge joint and then by twisting around the Ache can be brought to the plant to the two glass panels. For the purpose It is preferred that the axis depending on the changing thickness of the first glass sheets is displaceable in a position in which they have a predetermined, Consistent small distance from the first glass panel occupies. It is further preferred that the bristles from the axis in only one Direction or only in a narrow space segment extend and that at least as a result of twisting the second barrier, the axle with its the Bristles facing away from the first glass sheet applies when the bristles create the smaller, second glass sheet. At the side facing away from the bristles the axis is preferably a sealing band extending along the axis provided in order to achieve the best possible seal. The sealing tape preferably consists of an elastomeric foam which is compressible is and compresses tight against the first pane of glass. The sealing tape could be glued to the axle. It is cheaper, however, two to provide axially parallel clamping plates, which both the axis and the Clamping tape, preferably also clamp the bristles between them.

Preferably, the sealing tape between the two clamping plates is clamped so that it is deflected by bias to one of its sides, and though towards the side to which the sealing band is moved, if the second Barrier is twisted to bring them to the plant on the two glass panels. In this way it is ensured that the sealing tape always with a sufficient Pressure on the first glass plate acts.

In principle, however, it is also possible to use a barrier in which emanating from the axis bristles in opposite directions, preferably in one direction longer bristles than in the opposite direction. Instead of bristles, narrow elastomeric lamellae could also be used which project at right angles from the axis, e.g. Slats, which obliquely to the longitudinal direction of the axis on this base and thereby overlap. Particularly preferred are bristles, which combined to form a narrow brush are. Such a brush can be steplessly different adjust wide and different deep edge joints and these sufficiently tight complete because the spaces between the bristles close, when the bristles meet by twisting the brush on the second glass sheet and not only resiliently to these, but also create each other.

The second barrier then seals off particularly well if there are several layers in it of bristles are tightly packed together.

The glass panels are often sharp-edged and can injure the bristles. The Brush is therefore preferably interchangeably held in the second barrier, best between the already mentioned clamps, which also Hold the sealing tape.

The second barrier is intended to hit the spacer in the edge joint be introduced. As spacers metallic hollow profile rods are in use. Recently, however, thermoplastic spacers used, which are extruded in situ on the second glass sheet. Such thermoplastic spacers are when the glass panels are assembled and her interior is filled with heavy gas, not yet cured. For this Case, it is recommended that the axis of the second barrier at her the spacer facing end to provide a slightly crowned head, the crowned Surface consists of a material which on the freshly extruded Spacer, not or only badly liable. Usual materials for freshly extruded thermoplastic spacers are butyl rubbers (polyisobutylenes) and polyurethane. Surfaces or surface coatings on which these Materials not or poorly liable, are known to the plastics expert. Surfaces made of dusty silicone resin have proved their worth.

The second barrier, which is the flow of heavy gas along the spacer is to cooperate, cooperates with the first barrier, which one Flow away the heavy gas transversely to the longitudinal direction of the spacer verhindem should. As a first barrier can be used in principle a bar or a plate similar to those which are also used for this purpose in EP 0 539 407 B1 is disclosed and applied to the edge of the two plates. For a complete To allow interaction of the first and the second barrier is the first barrier preferably divided into two sections, one of which section around the axis of the second barrier is rotatable and has a slot through which through the second barrier is pushed forward and retractable. The two sections the first barrier can overlap one another. It is also possible in which a section of the first barrier is a circular or to provide circular section-shaped neck and therein the second, rotatable To arrange the section of the first barrier. That way, the second barrier penetrate the first barrier without gaps and an optimal sealing of the Edge joint in two directions cause.

The sealing of the edge joint in the third direction namely in the second Barrier wegführenden direction, can be carried out as described in EP 0 539 407 B1, namely by applying a bar, in which a nozzle integrated to supply heavy gas, to that adjacent edge of the insulating glass pane, at which the gap to the interior of the insulating glass on biggest one is.

The first barrier is expediently with a sealing favoring elastomeric material, especially with a Vulkollan, which opposite the stress due to the sharp-edged glass panel edges sufficient is stable.

Preferably, the first barrier and the second barrier are with the movable one Coupled plate of the assembly device and is the first barrier is against pivoting the edge of the two plates, with the first barrier at the same time the second barrier is pivoted. This pivoting movement is preferably performed in two steps, the second step being small in comparison the first step is so that after the first step the first barrier Already almost rests on the edge of the two plates. In this situation becomes the second Barrier pushed against the spacer and twisted and only then the first barrier is moved completely against the edge of the two plates. On this way, the rotatable portion of the first barrier can be rotated while still a small distance from the edge of the plates, so that his rotation is inhibited. The rotatable portion of the first barrier is preferably hingedly connected to the non-rotatable part of the first barrier, so that when pivoting the first barrier, the direction of the axis of the second Barrier can be preserved, which is the drive for moving the facilitated second barrier.

To drive the second barrier are particularly suitable a pinion and a in the alignment of the axis of the second barrier arranged rack, which with the second barrier is coupled and with which the pinion meshes.

The angle of rotation of the second barrier may vary depending on the distance be selected on both glass panels. Preferably, however, is independent of Distance between the two glass panels adhered to a fixed angle of rotation, to which preferably a fixed stop is provided, which determines the angle of rotation of the second barrier limited. This is a particular advantage of using a narrow brush whose bristles can be bent to different degrees and in this way without changing the angle of rotation to adapt to different Allow clearances of the glass panels.

It is a particular advantage of the invention that it lends itself to the edge joint, in which the wedge-shaped gap between the first glass sheet and the Spacer is not only to seal in graded insulating glass panes, but also with insulating glass panes, which formed from two equal sized glass panels are. Preferably, for this application on the rotatable section the first barrier also has a third barrier formed of bristles provided, the bristles extend obliquely to the surface of the first barrier. These bristles are suitable for shutting off, as disclosed in EP 0 539 407 B1 an edge joint of a non-stepped insulating glass pane, whereas they is largely ineffective in a stepped insulating glass pane. The third barrier makes it possible to use the second barrier when producing non-graded insulating glass panes in their withdrawn, ineffective position, whereby the second barrier is spared and not changed so often got to. But even without such a third barrier, the edge joint of a not stepped insulating glass pane sealed by advancing the second barrier become.

The mode of action of the device according to the invention does not depend on the orientation the plates of the assembly device. Preferably, the Both plates, as it is today mostly used, almost vertical arranged. However, the invention is also applicable to assembly devices, in which the two plates are arranged horizontally and the insulating glass panes be assembled lying down. In an assembly device with approximately vertical plates is the sealed edge joint with the wedge-shaped gap between the first glass sheet and the spacer expediently at the bottom of the two plates and the heavy gas is from the side, at the adjacent, from bottom to top leading edge introduced into the space between the two glass panels, preferably near the bottom. The heavy gas then displaces from below the lighter air, floating on the heavy gas, so to speak, upwards is displaced. It is particularly important to make sure that Heavy gas does not run out of this at the bottom of the insulating glass pane.

While the device for filling the heavy gas in the EP 0 539 407 B1 disclosed device in the form of a bar or bar at the movable plate is attached, it is in the inventive device preferably on the fixed plate or on the frame of the assembly device and is used when assembling stepped insulating glass panes pushed forward towards the moving plate until it comes with a along the beam or ledge running seal on the first glass panel strikes, which protrudes beyond the edge of the second plate, since they are at a stepped insulating glass pane is larger than the voltage applied to the first plate second glass panel. With a second seal, the device sets for filling of the heavy gas to the parallel edge of the first plate. Become assembled in the assembly device ungestufte insulating glass panes, sets the means for filling the heavy gas with their two parallel seals to the outlet edges of the two plates at.

Figures 1 and 2 show that the device is a subframe 1 and one Base 2 has, which carries a horizontally conveying conveyor, through a series of synchronously driven rollers 3 is formed. Between every two adjacent rollers 3, a support 4 is arranged; the result of the support 4 is arranged on a designed as a lifting bar 5 lifting device, which on and is adjustable from, so that the support 4 between a position in which they protrude above the rollers 3 upwards, and a situation in which they under the Top of the rollers 3 are sunk, back and forth are displaced.

Above the rollers 3, a support wall 6 is arranged, which on the one hand the base 2 and on the other hand by struts 7 and 8, which on the base 1 feet, in about 6 ° from the vertical to the rear inclined position is supported. The support wall 6 is formed as an air cushion wall. It has a first plate 9 in which a number of holes are distributed, which is supplied by a blower 10 via a line 11 compressed air. The Front of the support wall 6 forms a first positioning surface 28 for a first Glass panel 40 and for a second glass panel 42.

On the frame of the support wall 6 are close to the four corners of the support wall four in Right angles to the support wall 6 extending rods 12 are arranged, which perpendicular to the support wall 6 by a pressure-medium-operated cylinder 13 before and are retractable. The rods 12 carry at their front end one Holder 14, to which a frame with a second plate 15 is attached, the runs parallel to the support wall 6 and by pressing the pressure medium cylinder thirteenth can be changed in their distance from the support wall 6. The second plate 15 is also formed as an air cushion wall and is therefore by another Line 17 connected to the blower 10. It has as the support wall 6 over its surface distributes a number of holes 35 through which the air blown can either emerge or be sucked. Their front side forms a second positioning surface for the first glass sheet 40. Below the second Plate 15 is another lifting bar 18 with a number of supports 19 arranged.

The discharge-side end of the second plate 15 with respect to the conveyance direction through a strip-shaped, extending from the lower edge to the upper edge of the Plate 15 extending suction device 20 is formed, which consists of a number of one above the other arranged suction cups 21, which via pipes 22 and 23 are connected to a suction unit, not shown, and individually or can be activated in groups. The outlet end of the suction device 20 is aligned with the outlet side edge of the first plate. 9

In the conveying direction 25 to the suction device 20 is then a cover 26 provided, which in the conveying path of the insulating glass panes and out can be moved out of the conveyor.

As shown in FIG. 3, the suction device 20 comprises a metal sheet 50, which is common with the rest of the plate 15 to be bent glass sheet 40 by suction holds. The sheet 50 extends from the lower edge to the upper edge the plate 15, which at its outlet side edge rigid with a metal plate 51 is connected, the front opposite the front of the second plate 15 is set back. The sheet 50 is fixed to the front of the metal plate 51 connected and protrudes in the conveying direction 25 beyond the metal plate 51 addition; the Sheet 50 is in this way by one-sided clamping on the outlet side Edge of the rigid portion of the second plate 15 is attached. As a result of his one-sided Tightening, the sheet 50 transverse to its surface by elastic Bending will be deflected. To accomplish this, is on the outlet side Edge of the sheet 50 by means of a hinge 52 hinged a plate 53, which at the back by struts 54 and 55, which at right angles extend to the surface of the plate 53, connected to a further plate 56 is such that the plates 53 and 56 with the struts 54 and 55 form a frame, which protrudes parallel to itself and to the front surface of the plate 15 and is movable back. The parallel guidance of the frame is achieved by a four-bar linkage ensured, which by the clamping of the sheet 50 at the metal plate 51, by the hinge 52 and by two in corresponding Distance arranged, behind the plate 56 lying joints 57 and 58 formed is, of which the joint 57 fixed to the plate 56 and the hinge 58 with the base frame of the second plate 15 is connected, wherein the two joints 57 and 58 are interconnected by a link 60.

The mechanism for shifting the frame 53 to 56 comprises two inflatable ones Hoses 61 and 62. The hose 61 is between the plate 53 and the front of a column 63 extending between the plates 53 and 56, which belongs to the base frame 59 and thus is fixed to the frame. Of the Hose 62 is between the plate 56 and the back of the pillar 63 arranged.

If the rear hose 62 is inflated and the front hose 61 is vented (Figure 3), then the plate 53 is retracted until it is adjustable Stop 64 abuts against the base frame 59. With the plate 53 moves the outlet side edge of the sheet 50 back, which is bent by it. If both hoses 61 and 62 vented, the sheet 50 returns by elastic Return spring back to its original position, in which it with its coated Front in the alignment of the positioning surface 29 is located. Will be complementary inflated the front tube 61, then the sheet 50 is in position stabilized, wherein provided on the rear plate 56 adjustable stops 65, which strike the base frame 59, ensure that the suction device 20 with its front not pushed over the positioning surface 29 addition becomes.

The front side of the sheet 50 is provided with a layer 66 of an elastomeric Material, in particular made of rubber, provided, for subdivision and limitation the individual sucker 21 strip-shaped, compressible seals, z. B. made of sponge rubber, are embedded in the layer 66. This strip-shaped Seals 67 give each sucker a rectangular outline shape in the middle a suction opening 68 is located (Figure 2). The strip-shaped seals 67 are over the front of the layer 66 before and are sucked in the first Glass plate 40 compressed.

When bending the plate 50, the sucked glass plate 40 is bent, resulting in an insulating glass 44, which is located between the first Plate 9 and the second plate 15, forms a slit-shaped opening 43, which lies on the outlet-side edge of the insulating glass pane 44 (see FIG. 3). Through this gap-shaped opening 43 can in the interior of the insulating glass pane a gas other than air, in particular a heavy gas, blown and the air is displaced from the interior. As a device for feeding of the gas is a nozzle 31 is provided (Figure 10 and Figure 12), which in the Neighborhood of the lower corner of the insulating glass pane 44 at the outlet side Edge is brought to the plant. The nozzle 31 is located at an elongated Angle rail 32, which is a part of the cover 26, that for covering the entire outlet side edge of the insulating glass pane 44 is used and is movably mounted on the support wall 6. The vertical slit-shaped Opening 43 sits at the top and bottom of the glass panels 40, 42 in a wedge-shaped gap 24 continues (see Figure 10).

In the amount of the roller table 3 is pivotally on the second plate 15, a first plate-shaped barrier 27 is provided, which on its upper side a support 98 carries a resilient sealing material and to the plant at the bottom the two plates 9 and 15 and optionally the insulating glass 44 determined is (see Figures 2, 9 and 11). This should along the wedge-shaped gap 24, which forms when bending the glass plate 40 at the bottom, the lower edge joint 45 of the insulating glass pane are sealed towards the bottom. So that at this point the filled heavy gas is not along the spacer 41 flows through the edge joint 45, at the first barrier 27 is still a second Barrier 38 provided with a brush 90 which is inserted into the edge joint 45 can be when the first barrier 27 to the lower edge of the plates. 9 and 15 is laid. To raise and lower the first barrier 27 is a Pressure medium cylinder 81 is provided.

As shown in FIGS. 4 to 7, the first barrier 27 is a horizontal one Axis 70 pivotally mounted on a support 71, which in turn with Help of two horizontal guide rods 72 and 73 on the movable Plate 15 of the assembly and pressing device attached and with the help of a horizontal pneumatic cylinder 74 relative to the surface of the movable Plate 15 is slidable. The first barrier 27 has a first section 75, which is pivotally mounted about the axis 70 on the carrier 71 and has a second portion 76 in the form of a circular plate which um a vertical axis 77 is pivotally mounted on a support 78, which about a horizontal axis 79 pivotally mounted on the first portion 75th is appropriate. The axes 70 and 79 are parallel to each other.

The carrier 78 is not only by means of the first portion 75 of the first barrier 27, but also connected to a parallel handlebar 80 with the carriers 71, so that the carriers 71 and 78, the section 75 and the handlebar 80 a Forming quadrilateral, which is a parallel displacement of the carrier 78 and enable him with the second section 76 of the first barrier, including the Carrier 71 and the carrier 78 connected by a pneumatic cylinder 81 with each other are. The pneumatic cylinder 81 is eccentric on a pin 82 mounted, which rotatably mounted in the carrier 71 and by a pneumatic Cylinder 83 can be pivoted.

At the bottom of the second portion 76 of the first barrier is a sheath 84 which receives the second barrier 38, which by means of a fork 85 pivotally connected to a vertical rack 86, which is connected to a Pinion 86a meshes. By driving the pinion 86a, the second barrier can turn off the ineffective position shown in Figures 5 and 6, in which they is below the surface of the second section 76, in an effective Position are pushed up, which is shown in Figure 11.

The second barrier has two clamping plates 87 and 88, which are screwed 89 are held together and on the one hand a flat brush 90 and on the other hand an elastomeric foam strip 91 pinch, which by clamping a ledge 92 in a direction away from the ledge 92 Biased direction. The second barrier 38 is narrow in the sheath 84 guided and is arranged so that they with the screws 89 on the axis 77th around which the second portion 76 of the first barrier 27 is rotatable. The Rotational movement is effected by a pneumatic cylinder 93 and has two end positions, one of which is shown in FIG. 4 and is thereby determined that the pneumatic cylinder 93 is fully retracted. The other end position results in that the rotatable portion 76 has one on its underside provided projection 94 abuts on a cam 95, which on the fixed Supporting wall 6 of the device is mounted.

Between the sheath 84 and the first section 75 of the first barrier is a third barrier 96 is provided, which is a flat brush is, which extends transversely to the sheath 84 and the bristles obliquely directed upward from the surface of the rotatable portion 76 of the first Barrier 27 emerge.

In a stepped insulating glass pane, the lower edge joint 45 according to the invention sealed as follows:

The two glass sheets 40, 42 are placed between the plates 9 and 15 of the assembly and pressing device arranged as shown in Figures 9 to 12 is: The larger first glass sheet 40 is positioned so that its lower Edge flush with the lower edge of the movable plate 15 terminates (FIG 9) and that their outlet-side vertical edge over the vertical edge of the plate 15 protrudes (Figure 10). The smaller, second glass panel 42 is positioned that their lower edge above the lower edge of the fixed plate 9 of the device is arranged (Figure 9), whereas its outlet side, vertical edge is flush with the outlet side, vertical edge of the fixed plate 9 (Figure 10). The altitude of the glass panels 40 and 42 is by the mutual Lifting beam 5 and 18 (see Figure 1) determined.

Are the two glass panels 40 and 42 positioned in this way, is by pressing of the pneumatic cylinder 74, the first barrier 27 depending on the thickness the first glass sheet 40 is positioned so that the vertical axis 77 in one for all Use cases are closely spaced before the inner surface of the first glass sheet 40 is (Figure 9, Figure 10). Then by pressing the pneumatic cylinder 81, the first barrier 27 is raised and shown in FIG bent shape in the elongated shape shown in Figure 6 transferred. In this position, the first barrier 27 still takes a small distance from the two plates 9 and 15, as shown in Figure 9. By advancing The rack 86 then becomes the second barrier 38 with that shown in FIG. 10 shown alignment, in which the brush 90 parallel to the glass sheets 40 and 42 extends, pushed up against the spacer 41. For the case that this consist of a still soft thermoplastic material should the second barrier 38 is in the region of its axis 77 with a convex Head 97 provided, which consists of a material to which the thermoplastic Material of the spacer 41 does not adhere. Then the rotatable Section 76 of the first barrier 27 by actuating the pneumatic cylinder 93rd twisted about the axis 77. Thereby, the strip 91 of the elastomeric Foam sealingly pressed against the first glass sheet 40 and the bristles of Brush 90 bend against the opposite second glass panel 42, wherein the bristles press against each other and in connection with the Foam strips 91 the cross section between the first glass sheet 40 on the a side and the second glass sheet 42 and the fixed wall 9 on the the other side from the spacer 41 down to the rotatable portion 76 of the Close first barrier 27 (Figures 11 and 12). Now by pressing of the pneumatic cylinder 83 of the eccentric bolt 82 is rotated and thereby the first Barrier 27 completely to rest at the bottom of the two plates 9 and 15 brought. In this case, the first barrier with an elastomeric pad 98 seals the lower edge joint 45 down from. The second barrier 38 seals the lower one Randfuge at a point behind the starting point 99 of the wedge-shaped Gap 24 is located, down to the inlet side of the assembly and pressing device. On the opposite side, the edge joint 45 is sealed by the Covering element 26 with a first vertically extending seal 100 against the first glass sheet 40 and with a second vertically extending seal 101 against the fixed plate 9 is placed, whereby the vertical edge of the still is sealed open insulating glass pane. In the lower part of the cover 26, a nozzle 31 is provided, which heavy gas through the gap 43 between the first glass sheet 40 and the spacer 41 in the space between the two glass panels 40 and 42 can flow and the therein initially displaced air displaced upward. That at the bottom Cover element 26 cooperating with the first barrier 27, the first barrier 27 and the second barrier 38 together ensure that the heavy gas can not flow down from the still open insulating glass pane and lost. When the desired amount of heavy gas is filled in, the bend will be made the plate 15 undone and thereby the column 24 and 45 between the first glass sheet 40 and the spacer 41 is closed.

If ungraded insulating glass panes are to be filled with a heavy gas, then the two glass panels 40 and 42 are arranged congruently, as in FIG. 1 and described in EP 0 539 407 B1. In this case can a discharge of heavy gas along the lower leg of the spacer 41 is prevented by the third barrier 96 instead of the second barrier 38 be immersed by their bristles in the lower edge joint 45 and below elastic bend to the downwardly facing side of the spacer 41st invest. The second barrier 38 can be sunk in its sheath 84 in this case stay.
