The invention relates to a device with signs of restrictive part of paragraph 1 of the claims. The invention relates also to a method of overlaying a remote tape on the window glass.
Typically the spacer between the panes of glass comprising two or more window panes consist of aluminum or steel hollow sections.
From DE 3002904 known AS a spacer in the form of a ribbon with a rectangular cross-section, often called "Swiggle-Strip", which is provided with a protective film, comes from the supply reel or winder and use the device ("binding head"), fitted with a head that is installed with the possibility of rotation is superimposed on the window glass. Spacer, having the form of a tape made on the basis of butyl rubber are visco-plastic, have strong adhesive properties (which it is desirable to achieve a gas-tight connection first with the first, and then with the second window glass glass), have the viscosity is strongly temperature-dependent.
In the US 6378586 B1 disclosed a device for setting the adhesive spacers to separate, lying horizontally window glass. The known device comprises (Fig.9-13) superimposing two heads that put the spacer on one separate window glass, and each is th of superimposing two heads attached to a specific area of window glass. One superimposing the head 300 is attached only to the feed direction parallel to the edge of the window glass. Another superimposing the head 200 is moved by a combined movement of the window glass and the binding head, passing along the other three edges of the window glass. Thus, the binding head is known from US 6378586 B1 devices have another "problem".
Recently developed elastic-plastic remote tape, which is much less sensitive to temperature, on the basis of polyurethane or similar material, and which also have a rectangular cross-section, are more stable in respect of shape and size than the so-called "Swiggle-strip", on the line, which will later be outside, have a diffusion barrier, for example, by laminating aluminum foil, and on the narrow sides, intended for bonding with panes of glass, supplied by the manufacturer with a thin layer, is covered with a protective film before applying the tape, consisting of glue with strong adhesion.
From DE 102 12 359 AND a method and a device for applying such tape at least one window glass glazing unit, comprising at least two window panes.
From DE 103 50 312 AND known installation for the manufacture of glass, which which has a device for application of elastic-plastic tape. This device for application of elastic-plastic tape as a remote tape in the manufacture of glass includes a feed reel for the tape, several drive rollers for the tape and the presser head for tape mounted for movement relative to the first window glass. Unlike the prior art, is used elastic-plastic tape, side surfaces of which are not yet covered with glue. Moreover, it put on its both side surfaces only immediately before applying the tape. For this purpose between the supply reel and the presser head provided with nozzles, which are located opposite each other and cover the side surface of the adhesive tape.
In particular, in the case of the production of glass, consisting of several window glass, i.e. glass with three or more panes of glass, which are interconnected via a remote tape, when using the known device cannot work faster, saving time as is necessary to put a remote tape on the two window panes one after the other, and only after that the item has a glass connectivity with glass, equipped with a remote tape (=window glass with applied remote tape) and cover glass =glass window without superimposed remote tape).
Also in the manufacture of glass consisting of two glass panels, it was often possible to save time, if it would be possible to impose a remote tape simultaneously on several window panes.
The invention, therefore, is to provide a device and method specified in the beginning, in the manufacturing process of glass may impose flexible, in particular, elastic-plastic remote tape on the window glass with savings in time and with lower costs than before.
This problem is solved according to the invention using the device with signs of paragraph 1 of the claims.
Task relating to the method is solved by the independent claims of the invention directed to the method.
The predominant and preferred embodiments of the invention are subject of the dependent claims.
Due to the fact that the device according to the invention is provided by more than one binding head, it is possible to cover remote tape two window panes at the same time. Thus, it is possible the application of flexible remote tape saving time.
In particular, if using the device according to the invention should be covered with a remote tape window glass Odinak the howl of the same size and contour shape, justified embodiment of the invention, in which the binding head relating to the device according to the invention, installed with the possibility of synchronous movement.
In particular, the invention for the manufacture of double-glazed window with three panes of glass allows you to apply a method that works, for example, as follows: the first window glass (cover glass) is included in the installation, without applying to him the remote tape, and passes through the installation. After this second window glass, i.e. glass window, which should be applied remote tape (1-e glass supplied tape), moved up to second in the direction of movement of the binding head, there is captured by a retaining device, for example, sticks, measured and transferred to a holding device in a starting position for application.
As soon as it happens or as much as possible, overlapping in time the third window glass (2nd glass supplied tape is moved up to first in the direction of movement of the binding head, there is captured by another restraint provided there, and moved to its original position for application. Once this has occurred, both binding heads are driven and due to the combin who rowanna movement of the window glass, on the one hand (preferably in a horizontal direction), and superimposing heads in perpendicular relative to the movement direction (preferably essentially straight up and down), on the other hand, on the edge of both window glass is applied to the corresponding remote tape.
Due to the fact that the value of the first glass supplied from a tape in the field superimposing head, located on the output side, is measured with a device for measurement of window glass, the motion control heads for application, on the one hand, and window glass (with restraints attached to them), on the other hand, can be carried out in such a way that remote tape is applied (superimposed) at the desired distance from the outer edge of the window glass.
In a preferred form of execution for installation according to the invention after the device for sealing the beginning still open corners in the spacer and before the clamping pressure set after him, in particular, the pressure in which elements (camera) glass filled with gas, connecting the buffer tank. This buffer, which has, for example, six sections for window panes allows you to align the various workflows and processes between the device according to the invention, and p is the ECCA (filling gas). The press, in particular, the press, fill the glass with gas, can be performed with one or two movable clamping plates and the rest to be arranged and operated in such a way (similar), as it is known from EP 0 603 148 A, EP 0 674 085 A, EP 0 674 086 A or EP 0 087 674 A.

The form of the device for application (elastic-plastic) remote tape on the window glass during the manufacture of glass, consisting of several glasses, in the exemplary embodiment of the glass, consisting of three panes, as shown in figure 1 and 2 as an example, has the following basic structure.
The device includes a support wall 101 directed essentially vertically, in the normal case tilted back a few degrees, about 5° relative to the vertical, which held the window glass. Support wall 101 may be a wall with a roller, a wall with an air bag, or simply a wall with a smooth surface.
On the bottom edge of the supporting wall 101 is provided a linear conveyor 103 that has any form of execution and may, for example, to have a number of rollers or conveyor belts. Is also possible and in some circumstances it is preferable if the linear conveyor 103 is divided into several conveyor sections.
In the lower region of the supporting wall 101, in particular, closely above the linear conveyor 103 is provided to hold ewusie device for window panes subjected to trigger remote tape. These restraints are configured to withholding window glass to move horizontally, i.e. across the direction of movement of the binding head 107. For this restraint is equipped with, for example, suction heads, conveyor belts under reduced pressure, or the like
At a distance in front of the supporting wall 101 and parallel to it is provided by the linear guides 105 (vertical axis)oriented in the vertical plane, for superimposing two heads 107, which can be applied (elastic-plastic) remote tape on the window glass.
By superimposing the heads 107 are sent to remote tape from the supply reel, which is located in building 109. This housing 109 can be air-conditioned, i.e. performed in climatic chambers. Supply remote tape to impose heads can be carried out, for example, as is in itself known from DE 103 50 312 A.
In the example of execution between the two binding head 107 is provided a feeding device 199 for adhesives based on butyl rubber, which provides glue both binding head 107, so that by means of nozzles provided in superimposing the heads may be carried out NAS is safety (spraying) of the adhesive on the lateral surface of the remote tape.
Design superimposing heads 107 and devices, which provide for the supply reel, can essentially correspond to binding heads disclosed in DE 102 12 359 A.
Such a construction is described below based on Fig 3-6, which correspond to 1-4 of the document DE 102 12 359 A.
Superimposing the cylinder 107, which to avoid, as a rule, the four lateral edges of the window glass is installed is known in itself by the way with the possibility of step-by-step rotation around the axis B-B figure 5, includes functionally important in this relationship of parts, following in the direction of tape transport not shown from the supply reel to the place of application:
| - | The first conveyor 1 is driven with the ability to regulate through the device 50 automatic control by computer and two timing belts 2, 2' (compare with figure 4) and contains four rollers 11,12,13,14, of which respectively interact roller pair 11 and 13 and 12 and 14 and is optimally designed for belts of different widths. The conveyor 1 tape goes freely without tension vertically or on edge from a not shown supply drum (case 109). For this purpose, the supply reel is equipped with an actuator that maintains the subject by means of the automatic control by computer. |
| - | The conveyor 1 is adjacent equalizing section 3 directed arc (cf. figure 5), in which the tape is directed between the guide having the shape of a slit, consisting of three pairs 31, 32, 33 of guide and support rollers, so that it can be deflected transversely to its direction of transport in the lateral plane, but not in the vertical plane. |
| - | Leveling the plot ends at 3 guide 4 for the tape, which includes six rollers, followed by three pairs 5, 6, 7 rollers, which rotate the belt 90° in the "reclined" position. Other rollers 8 assume the lateral direction. |
| - | Then the tape is moved to the second conveyor 9 to the tape, which includes two cooperating rollers 91 and 92, which are driven by a toothed belt 93 to control by automatic control by computer. |
| - | The second conveyor 9 sends the tape to the place of application. It includes, along with the usual clamping rollers 10a (for horizontal shelf frame formed later) and 10 b (l the I vertical shelf frame, formed later), also conventional and therefore not illustrated in more detail below notching V compounds on us in the places in which the binding head is used for formation of an angle, and the arm 10c based 10d ribbon (cf. figure 4). The lever 10c is installed with the possibility of rotation and holds the ribbon in the new fallout, particularly when approaching a running corner and/or before, during and after cutting the ribbon at the end of the detour path window glass for the formation of a closed remote frame. |
| - | In the leveling section 3, namely on the narrow sides of the guide slit, limited roller pair 32, on the inner side of the arc is the first sensor 21 and on the outer side of the arc is the second sensor 22. The sensors 21, 22, in respect of which it could be, for example, reflex sensors, connected to the automatic control device using the computer and at the approach of the tape produces a signal. If the tape is approaching the sensor 21 due to insufficient feed conveyor 1 for the tape relative to the peripheral speed of the conveyor 9 to the tape determined by the rate of application at this moment, at this signal, the automatic control device slightly increases the number of revolutions of the drive and thus the environment and the top speed of the respective roller pairs 11, 13 (or 12, 14) of the conveyor belt 1 to the belt and, thus, prevents the tape was subjected to tensile stresses. If, on the contrary, the tape is approaching the sensor 22 located on the outer side of the arc, with excess supply conveyor 1 for the tape, it emits a corresponding signal to the automatic control device, after which it slightly decreases the ring rate of the corresponding roller of the pair of conveyor 1 to the tape and through this prevents the tape before the conveyor 9 to the tape was ocials and superimposed in such a state. |
Using the device according to the invention and the method according to the invention, in particular, in the manufacture of triple-glazed Windows (von Dreifach-Isolierglaselementen), resulting in improved cycle time, as you can cover the distance with a tape at the same time two window panes. Another benefit is that you want one (only) device 199 supply bootrom both heads 107 for application.
Further, the device according to the invention allows to hold up to eight different spacers in sections supply (climate chambers-buildings 109) device, so time is reduced replacement when changing remote tapes, or if desired other air chamber between the panes.
Arrange the creation according to the invention also enables the application of remote tapes of various sizes, in particular, the width, synchronously or asynchronously on two glass supplied ribbons, that it is desirable or required for double-glazed Windows with three panes of glass with different thickness of the air chambers.
The advantage of the device according to the invention is also the fact that there are separate areas of reliability, which is preferable for care, cleaning, and protection from water leakage.
7 shows a simplified, schematic top view of the installation for the manufacture of glass with the device according to the invention, containing two binding head 107, a linear conveyor 103, section 111 for closing angles in remote tape placed on the window glass, the drive 113 with sections 115 and press 121, for example, press for the gas filling, with two movable clamping plates.
The drive 113 is made adjustable in the transverse direction (arrow 114) to Orient the sections 115 of the rails 117.
Covering glass and window glass, on which is laid a remote tape as a spacer ("glass plate"), are transported by the linear conveyor 103 to the buffer memory 113 and arranged for intermediate storage in the sections until they need and in the correct sequence will not be moved from the buffer memory 113 in press 121.
The buffer, however, is Italy 113 also allows you to move the window glass back on the linear conveyor 103, that may be necessary if the lack of glass in a collectible package (for example, if it is damaged and should be deleted).
The buffer tank 113 can be configured so that the window glass (in particular, large-format glass) can be transported past the buffer memory 113 directly in the press 121.
Summarizing, we can describe the exemplary embodiment of the invention, as follows:
