Description

Composite pane and process for manufacturing and / or

Provision of a composite pane

The present invention relates to a pane assembly and a method for producing and / or providing a pane assembly according to the features of the independent claims.

Disc units or disc composites known from the prior art, as disclosed, for example, by DE 10 2009 057 156 A1, generally comprise at least two discs, which are arranged parallel and spaced apart from one another. A spacer is provided between the two disks, which can be designed differently and defines the distance between the at least two disks. In addition, a middle, preferably transparent, pane can be provided and / or arranged between the panes, which is inserted into a receptacle provided in the spacer. The middle pane can be, for example, an electrostatic plate or the like.

A cavity can be formed between the middle pane and the two outer panes, which can be filled, for example, by means of a filling gas. Alternatively, a vacuum can be created in the cavities.

In order to be able to use the at least one middle pane in the frame construction without contamination, in particular dirt, dust or the like, it has proven in practice to be necessary to assemble the at least one middle pane and / or the further panes in a clean room. Environment of a clean room. Such a clean room is a delimited room in which the concentration of airborne particles such as dust or other contaminants is kept very low, in particular below a defined limit. Thus, the at least one middle pane can be used in a clean room environment without further precautions in the frame construction and remains free from contamination after insertion.

However, both the provision of a clean room and its maintenance, servicing and use are usually costly and at the same time require complex and costly processes. Conventional solutions for the use of medium, in particular

Transparent and / or further panes in frame construction in assembly halls without such a clean room environment or without other special precautions generally do not allow cost-effective, industrially feasible, partially automated or fully automated processing of such panes and pane units, since the individual panes are particularly useful during their handling such as during local transport or cutting as well as when inserting into the

Washer construction are very prone to soiling and wear

consequently cannot be used in the frame construction without further pretreatment. Otherwise, especially after the

Assembling the disc units no longer accessible middle panes the cleanliness and absence of dust or other contaminants

be guaranteed.

In view of the practical limitations found in the prior art, the present invention is therefore based on the object of providing an improved method in which a pane assembly can be produced and / or provided inexpensively, without great effort and regardless of the external conditions. In addition, a composite pane is to be made available which can be produced inexpensively and in a simple manner, in particular by carrying out the improved method which justifies the invention

Procedure.

These tasks are accomplished through a manufacturing process and / or

Provision of a composite pane and solved by a composite pane according to the features of the independent claims. Advantageous refinements and developments of the invention are in the respective dependent claims

specified.

The invention relates to a method for producing and / or providing a pane assembly formed from a total of at least three panes, which can optionally also be referred to as a pane unit, the method comprising at least or in particular the following method steps in the order of enumeration or in a different order or can include, as will be explained below. In principle, the method according to the invention comprises at least the method steps i, ii, iii, iv, v, vi and vii listed below, it being possible to deviate from the sequence given here, depending on the method variant selected. This will also be explained in more detail below. The process thus comprises the steps: i. Providing at least one first disk and at least one second disk; ii. Providing at least one third slice; iii. Providing a frame structure which is prepared and designed at least for the reception of the third pane; iv. Stripping and / or cleaning of the at least one third pane before it is inserted into the frame construction or guided to the at least one first and second pane, with a defined and / or directed gas flow via the at least during a phase of stripping and / or cleaning a third disk is blown; v. Add the first pane and / or the second pane to the third

Disc and / or vi. Insert the first disc and / or the second disc in the

Frame construction; and vii. Forming the pane assembly, in which the first pane and the second pane are spaced apart, and in which the third pane is arranged in between and spaced from the first pane and from the second pane.

As already mentioned, according to a preferred exemplary embodiment, the above-mentioned method steps i, iii, vi, ii, iv and vii can be carried out in this order, the at least before the stripping and / or cleaning of the third pane and before its insertion into the frame construction a first pane and the at least one second pane have already been inserted into the frame structure can or alternatively can be inserted into the frame construction one after the other.

In the method according to the invention, it can optionally be provided that at least one third washer is inserted into the frame construction after the at least one first washer and the at least one second washer have been inserted into the frame construction or before the at least one second washer has been inserted into the frame construction.

If, in the context of the present description, there is talk of a first disk, a second disk and a third disk, this serves primarily to uniquely identify and clearly assign the individual disks, which therefore cannot be confused with one another. With the

However, labels are by no means an order when handling the

Disks or connected during their assembly.

One after the other in the sense of the above definition can mean in particular that the at least one first pane is first inserted into the frame construction and / or fastened there. The at least one third pane is then inserted into and / or attached to the frame structure, followed by the at least one second pane.

So that the at least one first pane and the at least one second pane can be or are inserted into the frame construction, the frame construction can in particular each comprise receptacles for the clear mechanical fixing of the panes in the frame. In principle, this is optional

understandable, but generally indispensable recordings can each be designed to correspond to the thickness or thickness of the pane.

The at least one first pane and the at least one second pane can preferably be inserted into the frame construction or inserted into the frame construction one after the other in such a way that the at least one first pane and the at least one second pane are arranged parallel to one another and spaced apart from one another.

According to a further exemplary embodiment, method steps i, ii, iv, v and vii can be carried out in this order, after method step i and the provision of the first and second disks on at least one flat side of the a first spacer is attached and / or fastened, after which, during or after the implementation of method step v, the third flat is attached and / or fastened with its first flat side to the free end of the first spacer, or or after which to at least a second flat side a third disk a second spacer is attached and / or fastened, and after that the second disk is attached and / or fastened with its flat side to the free end of the second spacer, and wherein carrying out process step iv at least during a phase of attaching and / or Attaching the at least one third disk to the first spacer removes the at least one third disk and / or cleans it, and at least during a phase of stripping and / or cleaning at least one defined and / or directed gas stream is blown over the at least one third disk .

The first and / or the second spacer can in particular be designed to specify and / or form a distance between the first and third disks and between the second and third disks.

In particular, the first, second and third disks can each be arranged parallel to one another and spaced apart from one another.

According to a further alternative embodiment, the

Method steps ii, iii, iv, i, v and vii can optionally also be carried out in the order given, with the at least one first pane and / or the at least one second pane being inserted into the frame structure after the at least one third pane has been inserted into the frame be used.

In this exemplary embodiment, the at least one third pane can thus be inserted into the frame construction in time before the at least one first pane and / or the at least one second pane.

According to a further exemplary embodiment, method steps ii, iii, iv, i, v and vii can be carried out in the order specified, with the at least one first pane and / or the at least one second pane being inserted in time after the at least one third pane has been inserted into the frame construction The pane can be guided to the frame structure and / or to the respective flat sides of the third pane by means of spacers. It can be provided that the first and / or the second spacer are each integrally connected to the flat sides of the first, second and / or third pane and / or to the frame construction,

in particular glued. Alternatively, any other would be

Connection methods, such as non-positive and / or positive connections possible, for example in the form of releasable snap-in connections or the like.

Furthermore, it can be provided that, for or in connection with the stripping, a coating located on the at least one third disk, which is at least on one side or on both sides, is removed. The coating can serve to protect the at least one third disk from contamination and / or damage such as dirt and / or dust particles and / or scratches. The coating can in particular be designed to be removable and / or detachable. The coating can be removed without residue.

In this connection, for example, antistatic and protective films that can be sprayed on or applied, in particular without any additional bonding, are suitable as coatings. In particular, it can

it can be provided that the coating is formed by a thin protective film or a thin protective film, which protective film and / or protective film is removed or removed with no residue and preferably with relatively little effort. The removal and / or the removal of the protective film and / or the protective film can preferably be carried out uniformly and with a preferably continuous removal movement. The protective film and / or protective film can be removed in a manual or automated manner, i.e. in particular using suitable mechanical handling devices.

If a protective film and / or a protective film is / are provided on each of the two flat sides of the at least one third pane, the removal of the

Protective film and / or the protective film on both sides simultaneously or sequentially. Simultaneously or immediately after the film or the protective films and / or coating, which may be present on both sides, are removed, the above-mentioned gas stream, which is important for the method according to the invention, can be activated in order to prevent dust and particles from adhering in the period between removal of the protective film and insertion the third pane in the frame construction or the Prevent assembly of the at least one third disc on the first spacer and / or as far as possible during assembly of the second spacer.

Alternatively, the at least one third disk can also be without one

Coating - formed, for example, by a film, as described above - are provided, the at least one third pane being cleaned before its assembly and / or handling, so that dust and / or dirt particles are removed from the at least one third pane. To clean the at least one third pane, cleaning and / or washing processes can be carried out with, for example, water - preferably deionized and / or distilled water - and / or cleaning agents. To dry the at least one third disk, at least one defined and / or directed gas stream can be blown over the at least one third disk. This optional gas stream can optionally be heated to accelerate the drying of residual moisture.

Alternatively, for cleaning the at least one third pane, only at least one defined and / or directed gas stream can be blown over the at least one third pane.

Furthermore, it can be provided that the defined and / or directed gas flow in or parallel to an insertion direction and / or counter to one

The direction of insertion of the at least one third pane into the frame construction or against a transport direction or assembly direction of the at least one third pane is blown at least on one side or on both sides over the flat sides of the at least one third pane.

In addition, the at least one defined and / or directed gas stream can be blown along the side of the at least one third disk on which the

Coating, in particular the protective film and / or the protective film, is removed. In particular, the at least one defined and / or directed gas flow in the pulling direction or counter to the pulling direction of the protective film and / or the

Protective film are blown, whereby the removal and / or removal of the protective film and / or the protective film can be supported and / or facilitated.

Alternatively, the at least one defined and / or directed gas flow can be in

Direction of removal or against the direction of removal of the coating provided on one or both sides of the at least one third disk. The defined and / or directed gas stream blown over the at least one third disk can contribute to the fact that impurities such as dust particles or the like can get into the third disk when it is inserted

Frame construction and before closing the interior between the spaced outer or delimiting panes can not deposit on a surface of the at least one third pane, which is disadvantageous, for example, after inserting the at least one third pane in the

Frame construction and in particular after manufacture of the pane composite, i.e. the at least one third disk can be kept free of dirt and dust particles.

In addition, it can be provided in the method according to the invention that the defined and / or directed gas stream is blown approximately parallel or at an angle over the flat sides or both flat sides over the at least one third disk.

It can also be provided that the at least one defined and / or directed gas flow is continuous or discontinuous at least during a phase of stripping and / or cleaning via the at least one third disc and / or at least during a phase of inserting the at least one third disc is blown into the frame construction.

Alternatively, it can also be provided that several, in particular at least two, three or more, defined and / or directed gas streams are blown over the at least one third pane at least during a phase of stripping and / or cleaning and / or assembly. In such an embodiment, the gas streams can, for example, be blown independently of one another over the respective panes which are required for producing and / or providing a laminated pane. Alternatively, a common gas stream, which is composed of individual gas streams, can be blown over individual disks or over all disks.

In the method according to the invention, it has proven to be advantageous that the surface quality of the at least one third disk and of the further disks is maintained as in the delivery state, in particular without dirt and / or dust particles. In addition, the at least one third pane and the further panes can be placed in any assembly location in an assembly hall without any special precautions the frame construction can be used. This enables pane composites, such as multi-pane insulating glazing, to be manufactured inexpensively and of high quality.

Furthermore, it can be provided that as a more defined and / or directed

Gas stream A pure or ionized air stream or nitrogen stream or similar gas mixture over which at least a third disk is blown. Also blowing the at least one third pane with a suitable inert gas or

Noble gas mixture may be useful.

It would also be conceivable that the at least one defined and / or directed gas flow at least during a phase of inserting the at least one first pane and / or the at least one second pane into the frame construction and / or at least during a phase of attaching the at least one first and / or second disk can be blown on the spacers in order to keep these disks free from contamination.

Furthermore, it can be provided that spaces are formed between the panes inserted into the frame construction, in which

At least one filling gas is filled in between, or in which approximately a vacuum is generated.

Alternatively, the gaps can also be produced and / or produced by means of the spacers, in which gaps a filling gas is filled, or in which a vacuum is approximately generated.

The gaps can each be filled with a filling gas such as air or noble gases or the like filling gases. Alternatively, the

Gaps are approximately vacuumized or a vacuum can be created in the gaps, for example, by means of a vacuum pump or a suction fan or the like. When a vacuum is mentioned in this context, it means a substantial removal of air in the interstices, but not an actual or absolute vacuum, which is technically difficult to produce with reasonable effort. Rather, it is meant that in the

There should be a very low residual pressure between the spaces. The gaps can be hermetically sealed at least after filling the gaps with at least one filling gas or at least after the gaps have been vacuumed, ie the gaps can be at least largely sealed airtight from the surroundings. For hermetic or airtight sealing, for example, seals or other parts or components can be used which are suitable or suitable for this.

Alternatively, it would also be conceivable to insert a fourth pane, fifth pane or a plurality of panes into the frame construction or to place them spaced between the first and second panes by means of spacers, the prior stripping and / or cleaning and / or insertion of the panes as in the at least a third disc has to be made.

The illustrated embodiments merely represent examples of how the method according to the invention or the device according to the invention can be designed and do not constitute a final limitation. 1 illustrates individual steps for implementing an embodiment of the method according to the invention for producing and / or providing a pane assembly 10 formed from a total of three panes, which method comprises at least or in particular the following method steps in the order of enumeration or in a different order:

In a method step S-i, at least one first disk 12 and at least one second disk 14 are provided. In a method step S-ii, at least one third disk 16 is provided. So that the at least one third disk 16 is protected against contamination or damage such as scratches during transport and / or handling, a coating in the form of a protective film and / or a protective film is provided on both sides or on both flat sides. The coating, in particular the protective film or the protective film, is designed to be removable.

In a method step S-iii, a frame construction 30 is provided, which is designed at least for receiving the third pane 16. Depending on

Embodiment, the frame structure 30 can also include receptacles for the at least one first pane 12 and the at least one third pane 14, as is the case here.

In time before the at least one third disk 16 is inserted into the

Frame construction 30 or before being attached to the at least one first pane 12 and to the at least one second pane 14, it is necessary to decoat and / or clean the at least one third pane 16 according to a method step S-iv. At least during a phase of stripping and / or cleaning and / or during the insertion of the third pane 16 into the frame structure 30, a defined and / or directed gas flow is blown over the at least one third pane 16.

The defined and / or directed gas stream can be, for example, a pure or ionized air stream or nitrogen stream or the like. The at least one defined and / or directed gas stream is preferably blown continuously over the third disc 16 to be stripped during the stripping. The at least one defined and / or directed gas stream is preferably blown over the flat sides of the third disk 16 at least during a phase of the stripping. The protective film and / or the protective film are preferably removed and / or removed uniformly and with a continuous removal movement, the protective films and / or protective films located on both flat sides of the at least one third disk 16 being removed simultaneously or in succession.

Dirt and / or dust particles on the at least one third disk 16 can be blown away and / or kept away from the at least one third disk 16 by the at least one defined and / or directed gas flow. In particular, the at least one defined and / or directed gas stream is blown on both sides and preferably in parallel and / or at an angle over the at least one third disk 16.

Alternatively, the at least one third pane 16 can also be equipped and provided without a coating, so that it is cleaned in time before being inserted into the frame structure 30. In particular, the at least one third disk 16 can be filled with water and / or additionally with a

Detergent can be cleaned. At least during a phase of cleaning and / or drying the at least one third disk 16, as already described above, at least one defined and / or directed gas stream is blown over the third disk 16.

Alternatively, the at least one third disk 16 can also be cleaned only by means of the at least one defined and / or directed gas stream.

Then, according to a method step S-v, the first disc 12 and / or second disc 14 are attached to the third disc 16 and / or according to a method step S-vi, the first disc 12 and / or the second disc 14 is inserted into the frame structure 30.

According to a method step S-vii, a pane assembly 10 is formed in which the first pane 12 and the second pane 14 are spaced apart, and in which the third pane 16 is located in between and spaced from the first pane 12 and from the second pane 14 is arranged.

According to a method step S-i, at least one first disk 12 and at least one second disk 14 are provided. According to another

Method step S-iii provides a frame structure 30 which is designed at least for receiving the third pane 16. According to the present

In the exemplary embodiment, the frame construction 30 is also designed to accommodate the first pane 12 and the second pane 14.

According to a next method step S-vi, the first pane 12 and / or the second pane 14 are in the frame structure 30, in particular the

Recordings of the frame structure 30 used. After inserting the at least one first disk 12 and the at least second disk 14 into the receptacles of the frame structure 30, both disks 12 are fastened there.

According to method step S-ii, at least one third disk 16 is provided. As already pointed out in FIG. 1, the third disc 16 can be provided with a coating on both sides or on both flat sides, so that the third disc 16 is protected against contamination or against damage such as scratches during transport and / or handling . The

Coating is formed, for example, by a protective film or protective film.

Alternatively, the at least one third pane 16 can also be equipped and made available without a coating, so that it has to be cleaned before it is inserted into the frame structure 30.

So that the at least one third pane 16 can be inserted into the frame structure 30, it is necessary to close it according to method step S-iv de-coat and / or clean by removing the coating, in particular the protective film or film, and / or cleaning the pane 16.

At least during a phase of stripping and / or cleaning the third disk 16, at least one defined and / or directed gas stream is blown over the third disk 16. The removal of the coating and the blowing of a defined and / or directed gas flow over the third disk 16 and / or the cleaning of the third disk 16 takes place in accordance with the method described in FIG. 1 and should thus be included in the method shown in FIG. 2 .

According to method step S-vii, a pane assembly 10 is formed in which the first pane 12 and the second pane 14 are spaced apart, and in which the third pane 16 is located between and spaced from the first pane 12 and from the second pane 14 is arranged.

Before the process step S-iv and thus before the stripping and / or cleaning of the third disc 16 and before it is inserted into the

Frame structure 30, the at least one first pane 12 and the at least one second pane 14 have already been inserted into the frame structure 30 or the at least one first pane 12 and the at least one second pane 14 are inserted into the frame structure 30 one after the other.

If the at least one first pane 12 and the at least one second pane 14 have already been or are inserted into the frame structure 30, the at least one third pane is placed between the at least one first pane 12 and the at least one second pane 14 according to method step S-iv in the

Frame construction 30 used.

If the at least one first pane 12 and the at least one second pane 14 are inserted into the frame structure 30 one after the other, the first pane 12 is first inserted into the frame structure 30 and

the at least one third disc 16 is then inserted into the frame structure 30. Finally, the at least one second disc 14 is inserted into the frame structure 30.

In summary, it can therefore apply that the at least one third disk 16 occurs after the at least one first disk 12 and the at least one have been inserted second pane 14 is inserted into the frame structure 30 or before the at least one second pane 14 is inserted into the frame structure 30.

The spaces 20, 22 formed between the disks 12, 14, 16 can be filled with a filling gas or vacuumed as described in FIG. 1.

According to method step S-ii, at least one third disk 16 is provided, which can be provided with a coating on both sides or on both flat sides, so that the third disk 16 is protected against contamination or damage such as scratches during transport and / or handling is protected. The coating is formed, for example, by a protective film or protective film. Alternatively, the at least one third disk 16 can also be provided without a coating, so that it has to be cleaned before it is handled.

To produce a pane assembly 10, it is necessary to de-coat and / or clean the at least one third pane 16 in accordance with method step S-iv by removing the coating, in particular the protective film or film, and / or the pane 16 by washing - And / or cleaning operations are cleaned.

At least during a phase of stripping and / or cleaning the third disk 16, at least one defined and / or directed gas stream is blown over the third disk 16. The removal of the coating and the blowing of a defined and / or directed gas flow over the at least one third disk 16 and / or the at least one third disk 16 is cleaned in accordance with the method described in FIG. 1 and is thus intended to be included in the method shown in FIG. 3.

According to method step Sv, the at least one first disc 12 and / or the at least one second disc 14 are attached to the at least one third disc 16, with the first disc 16 having the first flat side at the free end of the first disc when carrying out method step Sv Spacer 18 is attached and / or attached. In addition, a second spacer 19 is attached and / or attached to a second flat side of the at least one third disk 16. The second disk 14 is then attached and / or fastened with its flat side to the free end of the second spacer 19.

In particular, it should be noted that under the implementation of the

Method step S-iv at least during a phase of attaching and / or attaching the at least one third disk 16 to the first spacer 18, the at least one third disk 16 is stripped and / or cleaned, and at least during a phase of stripping and / or cleaning at least one defined and / or directed gas stream is blown over the at least one third disk 16.
