Description

METHOD AND DEVICE FOR SEALING INSULATED GLASS BLINDS

The invention relates to a method and apparatus for sealing insulating glass blanks.

It is known and customary in the manufacture of insulating glass, the lying in an insulating glass blank between the glass and outside of the spacer, outwardly open edge joint of insulating glass blanks, consisting of at least two glass sheets joined therebetween spacer, which is connected to the glass sheets is to fill with sealant to the final composite of the glass panes of

To achieve insulating glass.

When sealing, so when filling the edge joint of insulating glass blanks with sealing compound, the sealing compound from at least one filling nozzle, which is moved along the edge joint of the insulating glass blank, introduced into the edge joint.

For the sealing of insulating glass blanks methods and devices are known.

On AT 511 084 A4, EP 0 337 978 A, FR 25 60 813 A, EP 0 252 066 A, GB-A-20 16 960, DE-OS 28 46 785, DE 29 07 210 AI, DE 28 16 437 Bl and EP 0 391 884 A1, for example, is referenced.

From EP 0391 884 AI a method for sealing of

Insulating glass blanks known in which the movement of the filling nozzle relative to the insulating glass blank depending on the

Delivery rate of sealant and the depth of the

Edge joint is regulated. The relative speed of the relative movement between insulating blank and filling nozzle is changed so that the desired extent of the filling of the edge joint even with changing depth of the edge joint and / or itself changing flow rate of sealant remains constant,

In DE 29 07 210 AI is a method for sealing of

Insulating glass blanks described in the throttling the supply of sealing compound always simultaneously with the

Slowing the movement of the insulating glass blank is done.

In particular, in the known methods for sealing insulating glass blanks, it is problematic to transport the insulating glass blanks during and after sealing, since sealing compound, as long as it has not yet hardened, is very sticky and contaminates transport means which are on

(lower) edge of the insulating glass blank attack. To solve this problem, various proposals for funding have been made. Reference may be made by way of example to AT 384 596 B, EP 0 122 405 A, EP 0 857 848 A and DE 34 00 031 C.

Both in the sealing of insulating glass blanks with a

Filling nozzle ("one-nozzle-sealing machine") as well as the

Sealing of insulating glass blanks with more than one

Filling nozzle, in particular with two filling nozzles ("two-nozzle sealing machine"), the movements between the at least one filling nozzle and the insulating glass blank to move the filling nozzle along the edge joint, by moving the insulating glass blank in the horizontal direction ( parallel to the conveying direction of the insulating glass blank) and moving the

Filling nozzle in the vertical direction (transverse to the conveying direction of the insulating glass blank) achieved. Thus, the insulating glass blank is linearly moved during the filling of parallel to the transport direction edge joints intermittently and the filling nozzle moves in the stationary insulating glass blank transversely to the conveying direction when transverse to the conveying direction aligned edge joints are to be filled.

In known devices, the filling nozzle is at a transversely to Direction of conveyed beam, which is not fixed adjustable on the machine frame in the conveying direction, displaced. This also applies to devices with two filling nozzles. In the known sealing machines, the filling nozzle or the

Filling nozzles in the conveying direction of the insulating glass blank not movable.

Also known is a method of sealing insulating glass blanks ("Erdmann method") using an injection-sealing machine.

Erdmann's injection-sealing machine with the

Type designation "7500 Series Vertical IG Secondary Sealer" is arranged in an insulating glass line of the "Erdmann Vertical Insulating Glass (IF) Line" type (cf.

www. youtube. com / watch? v = GlwRurxOtVo, uploaded 02.10.2010).

The sealing machine has a retaining wall for

Insulating glass blanks which are formed by a plurality of beams permanently mounted in the machine frame and fitted with freely rotatable rollers. At the bottom of the retaining wall are linear conveyors in the form of conveyor belts with lateral guide rollers

(inlet side) and in the form of conveyor rollers (outlet side) provided. The inlet side linear conveyor is at

Running the Versiegeins lowered. Between the

inlet-side linear conveyor and the lowermost, equipped with rollers beams of the support wall are provided as holding means for the insulating glass blank to be sealed suction cups, which are adjustable transversely to the support wall back and forth. The suction heads can be attached to a sealed insulating glass blank. When sealing, the insulating glass blank is used exclusively by the suction cups, which are in the supporting wall

are arranged, held so that the edges of the insulating glass blank are free and the sealing nozzle along the four edges of the insulating glass blank can be moved around this, while in the edge joint of the insulating glass blank Sealant is filled. Each suction head is one

Assigned support fingers. The support fingers can be independent of each other about horizontal pivot axes

Ready position in an approximately horizontal Wirklage

be pivoted. When a triple insulating glass blank is to be sealed, a support finger is swung up from below in abutment with the lower edge of the insulating glass blank. The support finger is pivoted down when the

Sealing nozzle moved during sealing along the bottom edge of the insulating glass blank.

The problem with the known methods for sealing and in the devices proposed for this purpose is that because of not adjustable or displaceable in the conveying direction

Filling nozzle / filling nozzles, the movement of the insulating glass blank by a sealing station when sealing edge joints, which run transversely to the direction of movement of the insulating glass blank, interrupted and must be resumed. This prolongs the cycle time due to the braking and acceleration of the insulating glass blank. This problem occurs especially with large and heavy insulating glass blanks.

The invention has for its object to make the sealing of insulating glass blanks so that the disadvantages occurring during sealing by braking and accelerating insulating glass blanks are no longer given.

This object is achieved according to the invention with a method having the features of claim 1 on the one hand and with a

Device having the characteristics of the independent, on the

Device directed claim, on the other hand.

Preferred and advantageous embodiments of the invention are the subject of the dependent claims. The basic idea of the invention is that the at least one filling nozzle is moved parallel to the direction in which the insulating glass blank is moved during the sealing process during sealing, in particular at least during individual sections of the sealing insert. The filling nozzle can during the

Sealing in the same direction as the one to be sealed

Insulating glass blank or to be moved in the opposite direction.

In a possible embodiment of the invention

Method is to continuously move the insulating glass blank to be sealed during the Versiegeins, wherein the at least one Fülldüse is moved with the insulating glass blank, if not parallel to the direction of movement (conveying direction) of the insulating glass blank portions of the edge joint Insulating glass blanks are sealed.

In the invention, these are the deceleration (deceleration) and acceleration of the insulating glass blank to be sealed

Connected problems no longer exist.

In certain cases, it may happen that the insulating glass blank is stopped during sealing (short). Such a case is given, for example, if long (large) insulating glass blanks are to be sealed in the conveying direction. In such cases, the area in which the filling nozzle in

Can be moved conveying direction, too short, so that the filling nozzle arrives at the end of its range of motion, before the aligned transversely to the conveying direction, with

Sealing compound to be filled section of the edge joint of the

Insulating glass blank is filled (sealed). But this occurs only in exceptional cases.

Usually, the inventive method allows the insulating glass blank according to a preferred embodiment the process in the conveying direction is continuously moved optionally with different, high speeds.

Likewise, the possibility provided by the invention allows the filling nozzle also to be moved in the conveying direction, so that work is carried out for small insulating glass blanks such that only the filling nozzle is moved and the insulating glass blank is not moved or performs only slight movement in the conveying direction.

In the context of the invention is also considered, the

To change the speed with which the filling nozzle is moved, to adapt to the prevailing circumstances (size of the insulating glass blank, cross-sectional size of the edge joint of the insulating glass blank). The speed of the movements of the filling nozzle both in and transverse to the conveying direction does not have to be constant, but can also be changed within the scope of the invention during a sealing operation.

In the invention, the possibilities, not only the speed with which the insulating glass blank (in

Conveying direction), but also to change, in particular independently change, the speed with which the filling nozzle is moved, so that cycle times are optimized and the (horizontal) dimensions of the sealing station are reduced without the advantages of the invention

get lost.

Another advantage of the invention is the cycle times of the method and the invention

Adapt the device to the capacities of upstream and downstream equipment without adversely affecting the quality of the sealing of insulating glass blanks. This causes that in the sealing station upstream equipment parts (eg gas filling presses) no jam arises because the Sealing takes too long on the one hand and that downstream equipment parts (eg stacking devices) do not have to wait for sealed insulating glass blanks, ie finished insulating glass, on the other hand.

When sealing from parallel or at a deviating from the right angle to the conveying direction extending ("oblique") portions of the edge joint, the required relative movement between the filling nozzle and the insulating blank can be achieved by moving only the insulating glass blank or by both move the insulating glass blank and the filling nozzle in the conveying direction with divergent speeds.

When filling parallel to the conveying direction portions of the edge joint, the filling nozzle is not moved transversely to the conveying direction.

When "oblique" or "curved" sections of the edge joint are to be filled with sealing compound, the filling nozzle is moved transversely to the conveying direction in order to avoid the "oblique" or "curved" section.

Section of the edge joint to follow.

An advantage of the method proposed according to the invention in the sealing of insulating glass blanks lies in the fact that the sluggish regulation of the amount of sealant, depending

Time unit is discharged from the filling nozzle in the edge joint, can be compensated by the nimble control of the speed of movement of the filling nozzle and / or the insulating glass blank.

Another advantage of the method and device according to the invention is that the required in the prior art movements of the insulating glass blank without this is sealed ("empty runs") to this for the sealing relative to the at least one filling nozzle correctly to dispense, are dispensable.

In the description below, the sealing of

Insulating glass blanks that are transported (transported) during sealing, as currently common practice, substantially vertically aligned by a sealing device (sealing station). Nevertheless, the method of the invention is not for the sealing of vertically aligned insulating glass blanks limited. Rather, with the method according to the invention, it is also possible to move horizontally through a sealing device

Insulating glass blanks are sealed.

In the method according to the invention, for example, it is possible to work as follows:

First, the lower, horizontal, parallel to the conveying direction portion 13 of the edge joint of the insulating glass blank 1 is filled, wherein the insulating glass blank 1 is moved continuously. The filling nozzle 7 can be moved parallel to the conveying direction (arrow 17) of the insulating glass blank 1 with a deviating from the speed of the insulating glass blank 1 speed. However, the filling nozzle 7 does not have to be moved.

Then, with respect to the conveying direction rear, transverse to the conveying direction aligned (vertical) section 9 of

Filled edge joint of the insulating glass blank 1, wherein the beam 5 moves with the filling nozzle 7 (sealing nozzle) synchronously with the insulating glass blank 1 and the filling nozzle 7 moves to fill the rear portion 9 of the edge joint along the beam 5 downwards or upwards becomes.

When filling the upper, horizontal portion 11 of the edge joint of the insulating glass blank 1, the insulating glass blank 1 is further continuously moved so as to achieve a relative movement between the filling nozzle 7 and insulating blank 1. The filling nozzle 7 can be parallel to the conveying direction (arrow 17) of the

Insulating glass blank 1 are moved with a deviating from the speed of the insulating glass blank 1 speed, but does not have to be moved.

To fill the front, aligned transversely to the conveying direction, (vertical) section 3 of the edge joint is carried out as described in connection with the filling of the rear portion 9 of the edge joint of the insulating glass blank 1. When filling portions of the edge joint, which are aligned parallel to the conveying direction (arrow 17) of the insulating glass blank 1, the filling nozzle 7 on the sealing head 19 and the in

2 are stationary (V ₂ = 0) or are moved at a speed (V ₂ ) which is different from the speed (Vi) with which the insulating glass blank 1 is moved (V ₂ Vi). This also applies to

Sections of the edge joint of the insulating glass blank 1, which are obliquely aligned with the conveying direction (arrow 17), wherein when filling inclined portions of the edge joint, the filling nozzle 7 along the beam 5 is moved so that it follows this section of the edge joint. Analogously, when filling curved sections of the edge joint of an insulating glass blank can be worked.

The movement of the sealing head 19 with the filling nozzle 7 (and also the optionally provided second sealing head 21 with the filling nozzle 7) in the conveying direction (arrow 17) is effected by moving the beam 5.

For example, if the sealing station 15 has (only) one filling nozzle 7 (FIG. 1), it can be worked as follows:

Step 1:

The insulating glass blank 1 is moved by a conveyor 25 at a speed Vi in the direction of arrow 17 through the sealing station 15. The filling nozzle 7 fills with, for example, stationary beam 5 (V ₂ = 0) or at a deviating from the speed Vi speed V _{2 moved} beam 5 and resting in the direction of the longitudinal extent of the beam 5 sealing head 19 with the filling nozzle 7, the lower, horizontal portion 13 of the edge joint of the

Insulating glass blank 1. 2nd step:

The insulating glass blank 1 moves at a speed Vi in the direction of arrow 17 through the

Sealing station 15. At the same time, the beam 5 is moved with the sealing head 19 in synchronism with the insulating glass blank 1 at the speed V ₂ and in the same direction (arrow 17) as this, where Vi = V ₂ . It drives the

Sealing head 19 with the filling nozzle 7 along, relative to the conveying direction (arrow 17) rear, vertical portion 9 of the edge joint upwards (arrow 42) and fills the section. 9

3rd step:

The insulating glass blank 1 is moved at a speed Vi further in the direction of arrow 17.

The bar 5 with the sealing head 19 moves in

Direction of the arrow 17 at a speed V ₂ , which is different, in particular higher than that of the insulating glass blank 1 (V ₂ > Vi), wherein the filling nozzle 7 - due to the difference in the speeds Vi and V ₂ , with which the Insulating glass blank 1 and the beam 5 to be moved - along the upper horizontal portion 11 of the edge joint of the insulating glass blank 1 moves and fills them with sealant.

When the upper portion 11 of the edge joint of the insulating glass blank 1 to the conveying direction (arrow 17) is obliquely aligned or curved, the sealing head 19 with the

Filling nozzle 7 additionally moves along the bar 5, that the filling nozzle 7 the oblique or curved portion 11 of

Edge joint follows. In this case, the beam 5 can additionally be moved in (or against) the conveying direction (arrow 17) (where

V ₂ Vi). 4th step:

The insulating glass blank 1 is further and continuously moved in the sealing station 15 by the conveyor 25 at a speed Vi in the direction of the arrow 17.

At the same time, the beam 5 with the sealing head 19 with the filling nozzle 7 is moved synchronously with the insulating glass blank 1 and with the speed V2 in the same direction (arrow 17), where Vi = V2. In this case, the sealing head 19 moves with the filling nozzle 7 along the bar 5 down (arrow 42) and fills, relative to the conveying direction (arrow 17) front, vertical portion 3 of the edge joint of the insulating glass blank. 1

If for sealing insulating glass blanks a

Sealing station 15 is used with two filling nozzles 7, can be operated as described below with reference to FIG. 2:

Step 1:

An insulating glass blank 1 is moved by the conveyor 25 in the sealing station 15 at a speed Vi in the direction of the arrow 17. At the same time, the beam 5 with two sealing heads 19 and 21 (the sealing head 21 can also in the machine frame of the sealing station 15th

be appropriate), each with a filling nozzle 7 synchronously with the

Insulating glass blank 1 and in the same direction (arrow 17) as this moves at the speed V2, where Vi = V2 applies. The sealing head 19 with its filling nozzle 7 moves along the bar 5 upwards (arrow 42) and fills, relative to the conveying direction (arrow 17) front, vertical portion 3 of the edge joint of the insulating glass blank 1 with sealant. The second sealing head 21 remains inactive in this step.

2nd step: The insulating glass blank 1 is continuously moved at a speed Vi in the direction of the arrow 17. The bar 5 with the sealing head 19 and the sealing head 21 is stationary (V ₂ = 0) or is with one of the

Speed V deviating velocity V ₂ (V ₂ Vi) moves, the filling nozzle 7 of the sealing head 19 fills the upper portion 11 of the edge joint and the filling nozzle 7 of the second sealing head 21 fills the lower portion 13 of

Edge joint of insulating glass blank 1 with sealing compound.

Filling nozzle 7 along the beam 5 moves so that the filling nozzle 7 of the edge joint also follows the oblique or curved portion 11. In this case, the bar 5 can additionally be moved in (or against) the conveying direction (arrow 17) (where V ₂ Vi).

3rd step:

The insulating glass blank 1 is continued with a

Speed Vi is moved in the direction of arrow 17. The bar 5 with the sealing heads 19 and 21 is connected to the

Speed V ₂ in the direction of arrow 17 and synchronously with the insulating glass blank 1 moves. Where Vi = V ₂ .

At the same time the sealing head 19 moves with the filling nozzle 7, which has recently filled the upper portion 11 of the edge joint along the bar 5 downwards (arrow 42) and fills, based on the conveying direction (arrow 17) rear, section 9 of the edge joint of the Insulating glass blank 1 with sealing compound. In this step, the sealing head 21 is inactive.

Both in the operation of FIG. 1 ("one-nozzle sealing machine") and in the operation of FIG. 2 ("Two-nozzle sealing machine"), the speed Vi at which the insulating glass blank 1 is moved when sealing by the sealing station 15, not in all sections

(Steps) of the procedure to be the same. It is only important that the insulating glass blank 1 - except in the cases explained above - does not stop during the sealing process and the bar 5 with the at least one

Sealing head 19 when sealing transverse or at an oblique angle to the conveying direction aligned portions of the edge joint, emanating from the lower horizontal portion 13 of the edge joint, such as the sections 3 and 9 of the edge joints, in (or against) the conveying direction, for example synchronously with the insulating glass blank 1, is moved.

The inventive method is also suitable for the sealing of so-called mold disks, ie insulating glass blanks 1 with a shape deviating from rectangular or square shape (with at least one "oblique" and / or curved edge), as described above with respect to in the Fig. 1 and 2 shown operation has been explained.

The exemplary embodiment of a device (sealing station 15) according to the invention shown in FIGS. 3 to 6 comprises a machine frame 23 in and on which the various system parts are arranged.

In the machine frame 23, a conveyor 25 is provided for insulating glass blanks 1 to be sealed. The

Conveyor 25 includes suction cups 27 and the suction cups 27 associated with supporting elements 29. It is provided that the suction cups 27 on the rear, the machine frame 23 facing surface of a glass sheet 33 of an insulating glass blank 1 attack and the support elements 29 at the bottom (only) the front, facing away from the machine frame 23 glass pane 31 of the insulating glass blank 1 attack. Such is a move (Sinking) of the front glass pane 31 relative to the rear, held by the suckers 27 glass sheet 33 of the insulating glass blank 1 avoided. Furthermore, it is thus avoided that parts of the conveyor 25 with the in the edge joint of a

Insulating glass blank 1 introduced sealant in

Come in contact and pollute. Incidentally, the

Device 15 also for the sealing of insulating glass blanks 1 for step elements (the glass panes of the insulating glass blank 1 are not the same size) suitable.

The upper edge of the insulating glass blank 1 is replaced by a

Roller bar 35 is supported on the rear surface of the

Glass pane 33 attacks and is arranged in the machine frame 23 of height adjustable so that it can be adjusted transversely to the conveying direction (arrow 17) so that it engages the insulating glass blank 1 (only) in the region of the upper edge.

The conveyor 25 of the first embodiment (Fig. 3 to 6) comprises three conveyor units 37, each with five suckers 27 and associated therewith supporting elements 29, which on a

common support 39 are mounted, in particular the

Top view of Fig. 6 shows. The height alignment of the

Abstützköpfe 30 of the support members 29, the position of the lower edge of the front glass pane 31 of the insulating glass blank 1 can be adjusted accordingly.

The conveyor units 37, comprising sucker 27 and support members 29 are in the circuit (arrow 40 in Fig. 6) moves, so that in each case only the currently required conveyor unit 37 in the

Conveying plane of the insulating glass blank 1 is moved. Once an insulating glass blank 1 has been sealed and transported away, the feed unit 37, as shown in Fig. 6 right, back and back to the inlet side of the

Sealing station 15 moves back. The support members 29 are formed so that their Abstützköpfe 30 are lowered to allow them to fill

(Sealing) of the insulating glass blank 1 by the filling nozzle 7 does not hinder when the lower horizontal portion 13 of the edge joint of an insulating glass blank 1 is sealed.

For example, the support elements 29 are formed so that their Abstützköpfe 30 in the region of the filling nozzle 7 by the sealing head 19 associated with filling nozzle 7

Actuator 49 are lowered into the position shown in the front view (Fig. 4). For this purpose, articulated lever 51 of the supporting elements 29, which in operative position with their

Abut abutment heads 30 at the bottom of the front glass pane 31 of the insulating glass blank 1, kinked. In the operative position, which occupy the support elements 29 when they are not in the region of a filling nozzle 7, the buckles 51 are stretched. The articulated levers 51 are formed so that they do not buckle under the weight of the front glass pane 31 of the insulating glass blank 1, but only kink when in the region of

Joint 53 of a kink lever 51 on this by the

Actuator 49 force is exercised.

The sealing nozzle 7 is guided via a sealing head 19 on the substantially vertical bar 5 up and down displaceable (arrow 42). The bar 5 itself is along the

Machine frame 23 in the horizontal direction, ie parallel to the conveying direction (arrow 17), displaceable.

For this purpose, the bar 5 is slidably mounted with its lower end to a rail 43 arranged in front of the sealing station 15. Furthermore, the beam 5 is displaceably guided via a cantilever 45 on a guide rail 47 fastened to the upper edge of the machine frame 23.

The fact that the beam 5, on which the sealing head 19 with his filling nozzle 7 up and down slidably (arrow 42) is guided in the conveying direction (horizontal, double arrow 41) is displaceable, it can during the Versiegeins of sections of

Edge joint of the insulating glass blank 1 to be moved with this.

This allows the operation according to the invention, in which the insulating glass blank 1 during the Versiegeins in the

Sealing station 15 does not stop, but is constantly moving. The relative movements between the

Sealing head 19 with filling nozzle 7 and the edge joint of the

Insulating glass blank 1 are by moving the insulating glass blank 1 by means of the conveyor 25 and

Sectionally (temporarily) moving the filling nozzle 7 both transversely to the conveying direction (double arrow 42) and in the horizontal direction (double arrow 41) in or against the conveying direction
