"Device for the production of double-pane insulating glass units"

The invention "relates to an apparatus for the manufacture of Double glazing units with a washed Disc a frame-shaped spacer placed on the Spacer applied a second washed disc and the thus formed disc pack by introducing an adhesive into a gap between the outside of the spacer and the disc edges protruding above the spacer is limited, is glued.

Double-pane insulating glass is heat and sound insulating. That is based on the between the two panes of glass and the spacer frame trapped air. The sides of the glass panes facing each other are in the finished double pane insulating glass inaccessible. About fogging of the windows

409836/0554

To avoid from inside, the dew point of the trapped The air is so low that it "does not fall below the usually occurring degrees of cold can be.

Only double-pane insulating glass is used on the system according to the invention manufactured that are glued together. Multiple bonds are possible for this, in which the frame is first glued to the panes, before another glue is applied to the from the outside of the spacer frame and the pane edges limited space is introduced. In particular the invention is suitable for double-pane insulating glass, the glass panes with one preferably thermoplastic adhesive held together in the from the outside of the spacer frame and the Disc edges limited space is introduced without there being a separate gluing of the frame with the disks as needed.

In the case of double-pane insulating glass of this type, the air gap mentioned at the beginning is essentially after sealed on the outside. The air is dried by a hygroscopic mass. This can turn into one at this Purpose housed hollow spacer frames and act on the trapped air through recesses in the spacer frame. Minor leaks the bonding of the panes can also be compensated for by this mass.

To double-pane insulating glasses within the meaning of the invention Is it siah also with insulating glass units in which

409836/0554

2309A19

more than two washers are used and in which possibly more than one spacer and more than an air space that is sealed off from the outside is present.

The device according to the invention enables the implementation of the basic features within the framework of the introduction described manufacturing process steps to be carried out. It depends on that the spacer and the discs are precisely adjusted, and that the adjustment once achieved by Hardening of the adhesive is no longer lost.

It is known to use a conveyor for this purpose, which consists of individual pivotally mounted rollers exists that support the units. Such a conveyor is proportionate because of the large number of its roles complicated and also has the property that the disk packets are controlled by stops have to. After placing the spacer, this leads to considerable mechanical stresses on the disk package and thus to the risk that the disks or the spacer shift each other. Therefore these systems are only used for insulating glass units that receive the above-mentioned multiple gluing, because the first gluing of the spacer to the panes causes the panes and spacer to slip counteracts.

However, it is disadvantageous that the connection of the units finished with just one adhesive in this way.

-A-

409836/0554

is closed because the use of only one glue a higher degree of mechanization in the manufacture of double-pane insulating glass promises. In addition, misalignments also occur with glued spacers. Such units must be discarded because smearing occurs when the spacers are moved occur on the discs with the glue.

However, it is known to hold the units together with clamps after they have been folded. These Brackets, however, require manual labor, especially because of the associated lower degree of mechanization is disadvantageous. In addition, when the adhesive is introduced into the space between that from the outside of the spacer and the disc edges protruding above the spacer is limited, removed and reattached after the adhesive has been applied. You just want to go with work with an adhesive that is introduced into the space described and you want to extrude the adhesive, then brackets to be inserted and removed again by hand are out of the question anyway.

The invention is based on the object of providing a device for the purpose indicated above, which it allows the disk package after its largely automated adjustment in the vertical and to hold it in the horizontal until the adhesive has cured, without the introduction, in particular the extrusion of the adhesive in the space that is separated from the outside of the spacer and the

409836/0554

Spacer limited protruding disc edges is disabled.

According to the invention this object is achieved in that the device is designed as a table, the one for each has a unit provided support surface, which is used to prelimit the adhesive receiving Gap is mounted vertically adjustable in height to its plane, and that to hold the adjusted Disk package several clamps are provided, which are mounted one after the other such that they can be folded away from their clamping position and can be swiveled automatically into the clamping position.

Such tables ensure that the adjusted units no longer have to be moved on a conveyor to need. In a plant for the production of double-pane insulating glass units the tables can be set up stationary. The tables are preferred though in turn arranged to be movable in order to pass the various production stations in the manner of a conveyor belt to be able to.

The units are adjusted in three directions on the tables: the height adjustability of the support surface results in the vertical adjustment. The alignment in the horizontal plane can be done when placing the panes and in such a way that after the adjustment the Disk package is arranged in the cement of the table and so that it covers the support surface. This full center Adjustment has the advantage that Verctellein-

4 09836/0554

directions, especially on the extruder nozzles, - for the introduction of the adhesive, z. B. on the height adjustment the nozzles can be omitted.

According to a further feature of the invention, the support surface is made up of several adjustable support elements constructed, which are mounted in an inner frame that is perpendicular to the support surface is adjustably mounted in an outer frame. In this way, the alignment of the disk package in the vertical direction by moving the inner and outer frames relative to each other.

Each of the tables forming the device according to the invention can be designed so that its support surface corresponds to a disc format. But there are different on most production lines Disc formats need to be processed, it is useful to change the support area and set up in such a way that it can be automatically adapted to different pane formats.

According to the invention it is therefore proposed that the support elements be arranged at right angles in a grid-like manner to arrange intersecting coordinates and the outer frame in pairs to the table plane movable and parallel bars arranged at the coordinates of the grid to set up the panes and the frame in the middle of the table.

In such a device, the edges of the

409836/0554

Disc package exposed in that the Aüflagerelemente lying outside the base area of the unit be lowered.

The clamps can when passing through the extruder nozzles folded away v / earth. Since the Kleniretstellung automatically is restored, the adjustment of the disk package is not lost.

Appropriately, the invention is implemented so that the The inner frame is raised above the level of the outer frame. In particular, two lifting devices are used for this purpose, One of which is used to set up the disc and the second lifting device to carry out an additional one Hubes for spacers is used, which are taken into account by one of the first hub and as far as possible usual spacer height deviate downwards.

In a practical embodiment of the invention, the one lifting device is formed by eccentric rollers which the inner frame rests on, and which are adjustable via levers, while the other lifting device of wedges that can be engaged between rollers are formed, some of which are set up on the adjustable height Bearings for the eccentric axes are attached. Such wedges allow the eccentric rollers to a defined To raise the level.

According to the invention, the support elements can each have one Have ball caster to support the disc, wherein each ball transfer unit in the piston rod is

409836/0554

medium actuated piston mechanism is stored. By extending or retracting piston rods, the support surface of the table can be adjusted so that the edges of the pane are exposed.

The necessary control of the pressure medium that acts on the thrust piston gear of the support element, takes place according to the invention in particular by the Afford. When the bars are moved inwards, the piston rods lower with a certain advance so that in the end only the area enclosed by the strips remains.

The strips in the outer frame are also part of the invention stored and driven in pairs with the aid of spindles with right and left-hand threads. The bars receive buttons that are used to switch the drives assigned to the spindles. These buttons can according to Realized a further feature of the invention for setting up the glass panes with pivoting support heads that lie against the front edges of the glass panes. The swiveling of the heads enables After adjusting, to fold away the buttons and thereby the edges of the pane for applying the adhesive to release.

To set up the spacers on the strips, according to the invention, pivotable V-arm arms should be arranged so as to be movable will. These angle arms can be moved with the help of cables. It is useful to use the Support the angle arms on the lower disk, which is initially placed on the table, and attach them to the system with buffers

409836/0554

2309ΑΊ9

to provide the spacer. The thickness of the buffers corresponds to the extent to which the disc edges protrude over the outside of the ■ spacer. In this way it is possible to prevent the spacers, which mostly consist of flexible strips, from being grounded be deformed.

If the spacers are particularly long, the profiles may bend. To do this prevent, the invention provides on the strips holder for the spacers. These keepers will be expediently arranged in the middle of the strips, because this is where the greatest deflections occur. In particular the holder can be made ferromagnetic. If magnets are not used can, the central fixation of the spacers is done by appropriate mechanical devices, wosu the profile of the spacer is designed so that it snaps into place. Also the spacers should be designed to be foldable from the plane of the pane.

After adjusting the spacer, the buttons described above can also be used to adjust the second Disc can be used. Then the clamps are swiveled in and connected to the pane. The for Adjusting the disk package units used are unfolded. Then the disk package is included its edges free and can now be provided with the adhesive.

409836/0554

24 fastened and consist of compressed air cylinders 25 » the piston rods 26 of which can be extended vertically upwards, see FIGS. 2, 7 and 8. At the top of the Piston rods 26 are held in a socket 27 with a screw cap 28 ball rollers 29 on which the lower glass pane 3 of the multiple glass pane rests.

The piston rods 26 can be extended individually or in groups, so that a larger or smaller Support surface for the lower glass pane 3 of the multiple glass pane is created. The size is controlled the support surface by strips 31 - 33, which are attached to the outer frame 13 above the inner frame 14 are connected so that they can slide in parallel. The bars 30-33 sit on spindles 34 with screw threads are provided and driven via a chain drive 35 from a common drive, not shown will. A slip clutch is connected between the chain drive 35 and the drive. The drive of the spindles remains switched on until the glass pane 3 to be adjusted has reached its final position.

For this purpose, adjusting elements for adjusting the glass panes 2 are provided on the strips 30-33. These adjustment elements consist of support heads pivotably connected to the strips 30, as shown in FIG are. The support heads 36 sit on shafts arranged orthogonally to the longitudinal axis of the strips 30-31 and pneumatically grounded by means of air cylinders 38 in

409836/0554

their upright position pivoted (see Pig. 24) ·. At the support heads 36 are pivotably connected to each of the support elements 39, which by means of compressed air cylinders 40 can be pivoted against the front edge of the upper "glass pane 5".

The support heads 36 functionally work together with buttons 41, which signal when the support head 36 with the assigned bar 30-33 so far forward is that the glass 3 has reached its final position. The buttons 41 are one AND circuit summarized, which only switches off the drive of the spindles when all buttons 41 are actuated. In addition, the buttons 41 are also combined in an OR circuit that the Drive of the bars 30 - 33 switches from high gear to slow gear as soon as one of the support heads 36 touches the glass pane 3.

An adjusting element for adjusting the spacers 4 is shown in FIGS. This The adjustment element consists of a device that can be moved along the strips 30, 31 and against the spacers 4 pivotable angle arm 42, which is freely rotatable and adjustable in height on a vertical bolt 43 is appropriate. The bolt 43 sits on a carriage 44 which is connected to the strips 30, 31 by means of rollers 45 Rails 46 is movable.

The angle arm 42 is by means of a toggle joint 47 by a compressed air cylinder 48 vertically

represents. In addition, the angle arm 42 is through a Spring 49 held so that it can attack the corners of the glass 3 and move with his legs can place against the front edges of the glass pane 3. At the ends of the legs, the angle arm has 3 adjustable buffers 50 for the spacer to rest on 4. The distance between the outer surface of the buffer and the inner surface of the legs of the angular ridge 42 defines the distance between the spacers 4 and the end faces of the glass pane 3.

Furthermore, a holding element 51 in the form of a magnet holder is provided in the middle area of the strips 30-33, which, like the other devices, is pivotally connected to the bars 30-33 and by means of a joint 52 and a compressed air cylinder 53 in its upright position or from this can be swiveled out. The holding element 1 or the magnet holder consists essentially of a the end of a bolt 54 arranged magnet 55, which is pivoted against the spacer 4 and this holds in a predetermined position.

In addition to the holding elements 51, pivotable clamping devices 58 are arranged, which by means of toggle linkages 56 and pneumatic cylinders 57 are pivotable. Each clamp 58 has two clamping jaws sliding on bolts 59

60 a and 60 b, between which the glass panes 3.5 and the spacer 4 with the help of a compressed air cylinder

61 are clamped as shown in Figs.

In the area of the washing machine 6 for the lower glass panes 3, the lower glass panes 3 are on the The production table is rolled with its clean side up. Fig. 10 shows this state. The strips 30-33 are now moved against the front edges of the glass pane 3, so that the support heads 36 lie against the front edges of the glass pane 3. Those support heads 36 that are not within the area inscribed by the strips 30-33 are folded over into the rest position, and at the same time the buttons 41 are triggered in order to avoid blocking the control. The aligned and the adjusted position of the glass pane 3 is shown in FIG. 11..

When all buttons 41 of the support heads 36 have been actuated, the height of the inner frame 14 is adjusted so that that the multi-pane glass plate to be mounted or its front edges from the tools of the following Processing stations is reached.

After the production item in the storage area 7 arrives for the spacers 4, the spacers 4 are placed on the lower glass pane 3, as which Fig. 12 shows. Then the along the strips 30, 31 movable angle arms 42 against the corners of

- 17 409836/0554

Glass plate 2 driven, with the legs of the angle arms 42 against the front edges of the glass plate place and grip the buffers on the surface of the glass plate and adjust the spacers 4 (see Pig. 13). The holding elements 51 are then placed against the spacers 4, so that the relatively long profiles of the spacers 4 are secured against displacement and bending in the central area (Fig. 14).

The production table 2 is then in the area of Washer 6 driven for the upper glass plate and loaded there with the upper glass plate 3 (Pig. 15). The adjustment of the upper glass plate 3 is done in that the support elements 39 to the Support heads 26 are pivoted up and in the course of the pivoting movement, take along and adjust the upper glass plate 5 (FIG. 16).
