Abstract

When filling hollow molds, to be bent into spacer frames, with a hygroscopic material, the filling process is interrupted as soon as the material filled into the hollow molding has reached a location of the hollow molding where the latter is to be bent into a corner. At this location, the wall of the hollow molding which subsequently forms the inside in the spacer frame is made to bulge. Then introduction of hygroscopic material into the hollow molding is continued, interrupted at the next location of a corner, the walls are made to bulge, until four locations of the sidewall in the hollow molding have been provided with a bulge, and the hollow molding is completely filled. Also, a device is described suitable for performing the process. This device comprises a stamp (16) for indenting the hollow molding and an ultrasonic sensor which responds to the filling level of the hygroscopic material in the hollow molding.

Description

Die Erfindung betrifft ein Verfahren zum Füllen von zu Abstandhalterrahmen zu biegenden Hohlprofilleisten mit hygroskopischem Material, bei welchem das hygroskopische Material von einem Ende her in die Hohlprofilleiste gegebenenfalls durch einen Trägergasstrom unterstützt eingefüllt wird.The invention relates to a method for filling hollow profile strips to be bent into spacer frames with hygroscopic material, in which the hygroscopic material is filled from one end into the hollow profile strip, optionally supported by a carrier gas stream.

Aus der AT-PS 365 551 ist eine Vorrichtung zum Füllen von Hohlprofilleisten mit hygroskopischem Material bekannt. Die Hohlprofilleisten werden nach dem Füllen an ihren beiden Enden mit Schaumstoffpfropfen verschlossen und hernach durch Eckwinkel zu einem Abstandhalterrahmen zusammengesteckt.From AT-PS 365 551 a device for filling hollow profile strips with hygroscopic material is known. After filling, the hollow profile strips are closed at both ends with foam plugs and then put together to form a spacer frame using corner brackets.

Aus der DE-PS 2 907 838 ist es bekannt, im Zuge der Herstellung von Abstandhalterrahmen aus einem Metallband diese mit hygroskopischem Material zu füllen, bevor das Hohlprofil geschlossen ist, d.h. solange es einen im wesentlichen U-förmigen Querschnitt besitzt. Diese Arbeitsweise hat den Nachteil, daß im Bereich der Biegestellen (Ecken des Abstandhalterrahmens) hygroskopisches Material zerbröselt wird, was zur Folge hat, daß der dabei gebildete Staub durch die Perforationen an der Innenwand der Hohlprofilleiste oder durch den dort vorgesehenen Schlitz in das Innere der fertigen Isolierglasscheibe austritt. Wenn man schärfere Ecken biegen will, dann wird dies durch das eingefüllte hygroskopische Material behindert und es besteht die Gefahr, daß die Hohlprofilleiste, insbesondere deren Außenwand während des Biegevorganges aufplatzt. Auch die Bördelnaht an der Innenseite der Hohlprofilleiste kann beim Biegevorgang aufplatzen.From DE-PS 2 907 838 it is known to fill spacer frames from a metal strip with hygroscopic material before the hollow profile is closed, i.e. as long as it has a substantially U-shaped cross section. This procedure has the disadvantage that hygroscopic material is crumbled in the area of the bending points (corners of the spacer frame), with the result that the dust formed in this way through the perforations on the inner wall of the hollow profile strip or through the slot provided therein into the interior of the finished product Insulating glass pane emerges. If you want to bend sharper corners, then this is hindered by the filled hygroscopic material and there is a risk that the hollow profile strip, especially its outer wall, bursts during the bending process. The flanged seam on the inside of the hollow profile strip can also burst during the bending process.

Es ist daher schon vorgeschlagen worden, (FR-PS 2 449 222, DE-OS 2 905 841) beim Einfüllen von hygroskopischem Material in U-förmig geformte Metallbänder, die dann zu einem Abstandhalter-Hohlprofil geschlossen werden, im Bereich der später herzustellenden Ecken Schaumstoffklötzchen einzulegen, so daß dort kein hygroskopisches Material sein kann. Wegen der Probleme beim Biegen gefüllter Abstandhalter-Hohlprofilleisten, werden Abstandhalterrahmen, die z.B. nach dem aus der DE-PS 3 223 881 bekannten Verfahren hergestellt wurden, aus leeren Hohlprofilleisten nachträglich mit hygroskopischem Material gefüllt (vgl. AT-PS 365 551, DE-PS 2 907 838).It has therefore already been suggested (FR-PS 2 449 222, DE-OS 2 905 841) when filling hygroscopic material into U-shaped metal strips, which are then closed to form a spacer hollow profile, insert foam blocks in the area of the corners to be produced later, so that none can be hygroscopic material. Because of the problems with the bending of filled spacer hollow profile strips, spacer frames which have been produced, for example, by the process known from DE-PS 3 223 881, are subsequently filled with empty hygroscopic material from empty hollow profile strips (cf. AT-PS 365 551, DE-PS 2 907 838).

Ein anderer Vorschlag (DE-OS 3 312 764) besteht darin, beim Biegen von Abstandhalter-Hohlprofilen, die mit hygroskopischem Material gefüllt sind, die Außenseite des Profils während des Biegevorganges mit einer Druckwalze ständig zu walzen, um das hygroskopische Material aus dem Eckbereich zu verdrängen.Another proposal (DE-OS 3 312 764) is to constantly roll the outside of the profile with a pressure roller during the bending process when bending spacer hollow profiles that are filled with hygroscopic material in order to close the hygroscopic material from the corner area oust.

Aus der DD-PS 254 731 ist es bekannt, das Füllen von Hohlprofilleisten mit hygroskopischem Material durch Druckluft zu unterstützen.From DD-PS 254 731 it is known to support the filling of hollow profile strips with hygroscopic material by compressed air.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Gattung anzugeben, mit dem Hohlprofilleisten so mit hygroskopischem Material gefüllt werden können, daß sie sich problemlos zu Abstandhalterrahmen mit scharfen Ecken biegen lassen, ohne daß Gefahr besteht, daß die Hohlprofilleiste während der Biegevorgänge im Bereich der Ecken aufplatzt oder deformiert wird, oder das hygroskopische Material während des Biegevorganges zu Staub zerkleinert wird.The invention has for its object to provide a method of the type mentioned with the hollow profile strips can be filled with hygroscopic material so that they can be easily bent into spacer frames with sharp corners, without the risk that the hollow profile strip during the bending processes in Area of the corners bursts or is deformed, or the hygroscopic material is reduced to dust during the bending process.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Füllvorgang unterbrochen wird, so bald das in die Hohlprofilleiste eingefüllte hygroskopische Material eine Stelle der Hohlprofilleiste erreicht, in der eine Ecke zu biegen ist, daß die im Abstandhalterrahmen dann die Innenseite bildende Wand der Hohlprofilleiste eingewölbt wird, und daß das Einfüllen von hygroskopischem Material in die Hohlprofilleiste nach dem Einwölben der Wand der Hohlprofilleiste fortgesetzt wird, und so fort, bis in der Hohlprofilleiste vier Stellen der Seitenwand eingewölbt worden sind.According to the invention this object is achieved in that the filling process is interrupted as soon as the hygroscopic material filled into the hollow profile bar reaches a point on the hollow profile bar in which a corner is to be bent that the spacer frame then the Inner wall forming the hollow profile strip is arched, and that the filling of hygroscopic material into the hollow profile strip is continued after arching the wall of the hollow profile strip, and so on until four points of the side wall have been arched in the hollow profile strip.

Durch die erfindungsgemäße Verfahrensweise ist sichergestellt, daß im Bereich der Stellen der Abstandhalter-Hohlprofilleiste, die zur Bildung der Ecken eines Abstandhalterrahmens gebogen werden, praktisch kein hygroskopisches Material vorliegt, so daß der Biegevorgang nicht behindert wird. Zusätzlich erleichtert das Einwölben der später die Innenfläche des Abstandhalterrahmens bildenden Wand der Hohlprofilleiste den Biegevorgang ganz erheblich, wie dies aus der DE-PS 3 223 881 an sich bekannt ist.The procedure according to the invention ensures that there is practically no hygroscopic material in the region of the locations of the spacer hollow profile strip which are bent to form the corners of a spacer frame, so that the bending process is not hindered. In addition, the arching of the wall of the hollow profile strip which later forms the inner surface of the spacer frame considerably facilitates the bending process, as is known per se from DE-PS 3 223 881.

Die Erfindung betrifft weiters eine Vorrichtung zum Füllen von Hohlprofilleisten, die als Abstandhalterrahmen oder Teile solcher Abstandhalterrahmen für Isolierglasscheiben bestimmt sind, mit hygroskopischem Material, mit einer Einrichtung zum Einfüllen des hygroskopischen Materials in die Hohlprofilleiste, mit einer Auflage für die Hohlprofilleiste und gegebenenfalls mit einer Anordnung zum Erzeugen eines den Füllvorgang unterstützenden Trägergasstromes, z.B. einem Gebläse.The invention further relates to a device for filling hollow profile strips, which are intended as spacer frames or parts of such spacer frames for insulating glass panes, with hygroscopic material, with a device for filling the hygroscopic material into the hollow profile strip, with a support for the hollow profile strip and optionally with an arrangement to generate a carrier gas stream supporting the filling process, for example a blower.

Erfindungsgemäß ist diese Vorrichtung dadurch gekennzeichnet, daß ein Prägestempel vorgesehen ist, der zum Einwölben der die Innenfläche eines Abstandhalterrahmens bildenden Wand der Hohlprofilleiste auf die auf der Auflage liegende Hohlprofilleiste zu vorschiebbar und nach dem Ausführen eines Arbeitshubes wieder zurückziehbar ist und mit einer dem Prägestempel zugeordneten Fühlvorrichtung, die ein Steuersignal abgibt, sobald der Füllpegel an hygroskopischem Material in der Hohlprofilleiste die Fühlvorrichtung erreicht hat, daß der Prägestempel und die Fühlvorrichtung entlang der Auflage für die Hohlprofilleiste verschiebbar sind, wobei der wenigstens eine Antrieb für den Füllkopf und der Prägestempel stillsetzbar ist, sobald der Prägestempel an einer Stelle der Hohlprofilleiste angelangt ist, in der beim nachfolgenden Biegen der Hohlprofilleiste zum Abstandhalterrahmen eine Ecke ausgebildet wird.According to the invention, this device is characterized in that an embossing die is provided which, for arching the wall of the hollow profile bar forming the inner surface of a spacer frame, can be advanced to the hollow profile bar lying on the support and can be retracted after a working stroke and with a sensing device assigned to the embossing die , which emits a control signal as soon as the filling level of hygroscopic material in the hollow profile strip has reached the sensing device, that the embossing stamp and the sensing device can be displaced along the support for the hollow profile strip, the at least one drive for the filling head and the stamping die being able to be stopped as soon as the stamping stamp has reached a point on the hollow profile strip in which a corner is formed when the hollow profile strip is subsequently bent to form the spacer frame.

Weitere Einzelheiten und Merkmale des erfindungsgemäßen Verfahrens und der hiezu vorgeschlagenen Vorrichtung ergeben sich aus den Unteransprüchen und der nachstehenden Beschreibung des in der Zeichnung schematisch in Seitenansicht dargestellten Ausführungsbeispieles.Further details and features of the method according to the invention and the device proposed for this result from the subclaims and the following description of the exemplary embodiment shown schematically in the drawing in side view.

Die in der Zeichnung dargestellte Vorrichtung besitzt ein Gestell 1, das über Füße 2 auf einem Boden 3 abgestellt ist. Das Gestell 1 besitzt eine Auflage 4 für eine zu füllende Abstandhalter-Hohlprofilleiste 5 (die Hohlprofilleiste 5 ist überproportional dick dargestellt, um die Übersichtlichkeit der Zeichnung zu verbessern). Am oberen Ende der in der Zeichnung schräg abfallend ausgebildeten Auflage 4 ist ein Vorratsbehälter 6 für hygroskopischem Material (Molekularsieb) vorgesehen, von der eine Leitung 7 ausgeht, die durch ein Absperrorgan 8 verschließbar ist. Das freie Ende 9 der Leitung 7 ragt in das Innere der zu füllenden Hohlprofilleiste 5.The device shown in the drawing has a frame 1 which is placed on a floor 3 via feet 2. The frame 1 has a support 4 for a spacer hollow profile bar 5 to be filled (the hollow profile bar 5 is shown disproportionately thick in order to improve the clarity of the drawing). A storage container 6 for hygroscopic material (molecular sieve) is provided at the upper end of the support 4, which slopes away at an angle, from which a line 7 extends, which can be closed by a shut-off element 8. The free end 9 of the line 7 projects into the interior of the hollow profile strip 5 to be filled.

Am Maschinengestell 1 ist weiters wenigstens eine Führungsschiene 10 befestigt, die parallel zur Auflage 4, über dieser angeordnet ist. Auf der Führungsschiene 10 ist ein Schlitten 11 durch einen nicht gezeigten Antrieb, der als Antrieb mit einem Endloszahnriemen, einer Endloskette, einem Ritzel-Zahnstangengetriebe, oder einem Spindelantrieb ausgeführt sein kann, in Richtung des Doppelpfeiles 12 parallel zur Auflage 4 verschiebbar. An einem mit dem Schlitten 11 verbundenen Träger 13 ist ein Druckmittelmotor 14 vorgesehen, dessen Kolben eine Gleitführung 15 durchsetzt und der an seinen freien Enden als Prägestempel 16 ausgebildet ist. Es ist auch eine Ausführungsform denkbar, bei welcher Prägestempel auswechselbar an der Kolbenstange des Druckmittelmotors 14 befestigt werden können, um die Vorrichtung an verschiedene Profilformen und Größen anpassen zu können.At least one guide rail 10 is also attached to the machine frame 1 and is arranged parallel to the support 4, above the latter. On the guide rail 10, a carriage 11 is displaceable in the direction of the double arrow 12 parallel to the support 4 by a drive, not shown, which can be designed as a drive with an endless toothed belt, an endless chain, a pinion-rack gear, or a spindle drive. On a carrier 13 connected to the carriage 11, a pressure medium motor 14 is provided, the piston of which passes through a sliding guide 15 and which at its free ends as Stamp 16 is formed. An embodiment is also conceivable in which stamping dies can be exchangeably attached to the piston rod of the pressure medium motor 14 in order to be able to adapt the device to different profile shapes and sizes.

Der Träger 13 trägt an einem unter die Auflage 4 ragenden Arm 17 eine Fühlvorrichtung 18, die ein Steuersignal abgibt, so bald der Füllstand von hygroskopischem Material 19 in der Hohlprofilleiste 5 die Fühlvorrichtung 18 erreicht.The carrier 13 carries, on an arm 17 projecting from the support 4, a sensing device 18 which emits a control signal as soon as the fill level of hygroscopic material 19 in the hollow profile strip 5 reaches the sensing device 18.

Die beschriebene Vorrichtung arbeitet wie folgt:The described device works as follows:

Eine Hohlprofilleiste 5 wird auf die Auflage 4 aufgelegt, wobei sie an ihrem unteren Ende 20 vorher durch einen Verschlußpfropfen 21, z.B. aus Schaumkunststoff verschlossen wurde. Die Hohlprofilleiste 5, die eine Länge besitzt, die dem Umfang des aus ihr herzustellenden Abstandhalterrahmens entspricht, wird an der Auflage 4 durch eine nicht näher gezeigte Haltevorrichtung festgehalten.A hollow profile strip 5 is placed on the support 4, having previously been closed at its lower end 20 by a plug 21, e.g. was closed from foam plastic. The hollow profile strip 5, which has a length which corresponds to the circumference of the spacer frame to be produced from it, is held on the support 4 by a holding device, not shown in detail.

Nach dem Beginn des Füllvorganges oder noch vor dem Beginn desselben wird der Prägestempel 16 gegenüber der Hohlprofilleiste 5 so ausgerichtet, daß er an einer Stelle angeordnet ist, in der dann in der Hohlprofilleiste 5, nachdem diese mit hygroskopischem Material 19 fertig gefüllt worden ist, eine Ecke gebogen wird. Zum Biegen der Hohlprofilleiste 5 zu einem Abstandhalterrahmen kann z.B. die aus der DE-PS 3 223 881 oder die aus dem DE-GM 87 05 796 bekannte Vorrichtung verwendet werden.After the beginning of the filling process or before the start of the same, the embossing die 16 is aligned with respect to the hollow profile strip 5 so that it is arranged at a point in which a hollow profile strip 5 then, after it has been filled with hygroscopic material 19, has a Corner is bent. For bending the hollow profile strip 5 to form a spacer frame, e.g. the device known from DE-PS 3 223 881 or the device known from DE-GM 87 05 796 can be used.

Sobald nun der Füllstand des hygroskopischen Materials 19 in der Hohlprofilleiste 5 die Fühlvorrichtung 18, die beispielsweise auf Ultraschallbasis arbeitet, erreicht hat, gibt diese ein Steuersignal ab, das einerseits dazu ausgewertet wird, den Füllvorgang abzubrechen (das Absperrorgan 8 wird geschlossen) und anderseits den Druckmittelmotor 14 ansteuert, worauf sich der Prägestempel 16 vorschiebt und in der Wand 22 der Hohlprofilleiste (das ist die Wand, die später die Innenfläche des Abstandhalterrahmens bilden wird) eine muldenartige Vertiefung 23 erzeugt, indem die Wand 22 nach innen gewölbt wird. Der Prägestempel 16 wird dann wieder zurückgezogen und der Füllvorgang fortgesetzt. Während des fortgesetzten Füllvorganges wird der Prägestempel 16 und die Fühlvorrichtung 18 durch den nicht gezeigten Antrieb bis zur nächsten Stelle der Profilleiste 5, in der eine Ecke zu biegen ist, weiterbewegt (die in der Zeichnung dargestellte Stellung). Diese Arbeitsweise wird so lange wiederholt, bis in der Hohlprofilleiste 5 vier muldenartige Vertiefungen 23 eingeprägt worden sind und die Hohlprofilleiste bis zu ihrem an der Füllvorrichtung angeschlossenen Ende mit hygroskopischem Material gefüllt worden ist.As soon as the fill level of the hygroscopic material 19 in the hollow profile bar 5 has reached the sensing device 18, which works, for example, on an ultrasound basis, it emits a control signal which is evaluated on the one hand to abort the filling process (the Shut-off device 8 is closed) and on the other hand controls the pressure medium motor 14, whereupon the embossing die 16 advances and creates a trough-like depression 23 in the wall 22 of the hollow profile strip (this is the wall that will later form the inner surface of the spacer frame) by the wall 22 is arched inwards. The stamp 16 is then withdrawn again and the filling process is continued. During the continuing filling process, the embossing die 16 and the sensing device 18 are moved by the drive, not shown, to the next position of the profile strip 5, in which a corner is to be bent (the position shown in the drawing). This procedure is repeated until four trough-like depressions 23 have been embossed in the hollow profile strip 5 and the hollow profile strip has been filled with hygroscopic material up to its end connected to the filling device.

Es ist noch darauf hinzuweisen, daß die Auflage 4 für die Hohlprofilleiste 5 nicht unbedingt schräg ausgerichtet sein muß. Insbesondere wenn das Füllen der Hohlprofilleiste 5 mit hygroskopischem Material durch einen Trägergasstrom unterstützt wird, kann die Hohlprofilleiste 5 in der Vorrichtung auch horizontal angeordnet sein.It should also be pointed out that the support 4 for the hollow profile strip 5 does not necessarily have to be aligned obliquely. In particular, if the filling of the hollow profile strip 5 with hygroscopic material is supported by a carrier gas stream, the hollow profile strip 5 can also be arranged horizontally in the device.

A method of filling hollow section strips, to be bent to form spacing frames, with hygroscopic material, in which the hygroscopic material is inserted from one end into the hollow section strip, if necessary assisted by a carrier gas flow, characterised in that the filling procedure is interrupted as soon as the hygroscopic material inserted into the hollow section strip reaches a point in said hollow section strip at which a corner is to be formed, that the wall then forming the inner side of a spacing frame made from the hollow section strip is intended, and that the insertion of hygroscopic material into the hollow section strip is resumed after indentation of the wall thereof, and so on, until four points in the side wall of the hollow section strip have been indented, and the hollow section strip has been completely filled.
2. A method according to Claim 1, characterised in that the wall of the hollow section strip is indented to such an extent that the passage of hygroscopic material at the thus constricted inner cross-section of the hollow section strip is at least rendered difficult.
3. A method of filling hollow section strips (5), intended to serve as spacing frames or portions of such spacing frames for insulated glass panes, with a hygroscopic material, particularly molecular sieve, especially for carrying out the method according to Claim 1 or 2, with a device (6 to 9) for inserting the hygroscopic material (19) into a hollow section strip (5), with a support means (4) for the hollow section strip (5) aligned to extend horizontally or incline obliquely downwards away from the filling device (6 to 9), and if necessary with a means, e.g. a fan, for generating a carrier gas flow assisting the filling procedure, characterised in that there is provided a stamping die (16) which can be advanced towards the hollow section strip (5) lying on the support means (4) in order to indent the wall (22) of the hollow section strip (5) forming the inner surface of a spacing frame made from the hollow section strip (5), said stamping die (16) being also retractable after execution of a working stroke, and having, associated with the stamping die (16), a sensor device (18) which emits a control signal as soon as the filling level of hygroscopic material (19) in the hollow section strip (5) has reached the sensor device (18), that the stamping die (16) and the sensor device (18) are displaceable along the support means (4) for the hollow section strip (5), at least one drive means being provided for the sensor device and the stamping die (16), said drive means being stoppable as soon as the stamping die (16) has reached a point in the hollow section strip (5) at wich a corner is formed when the hollow section strip (5) is bent in order to form a spacing frame.
4. A device according to Claim 3, characterised in that the stamping die (16) can be advanced and retracted vertically relative to the longitudinal extension of the hollow section strip (5), i.e. vertically relative to the support means (4).
5. A device according to one of Claims 3 or 4, characterised in that the sensor device (18) and the stamping die (16) are disposed on mutually opposite sides of the support means (4).
6. A device according to one of Claims 3 to 5, characterised in that the sensor device (18), seen from the end of the hollow section strip (5) facing away from the filling device (6 to 9), is offset relative to the axis of the stamping die (16).
7. A device according to one of Claims 3 to 6, characterised in that the stamping die (16) and the sensor device (18) are disposed on a common carriage (11), movable by a drive means along the support means (4) for the hollow section strip (5), on a guide (10) which extends parallel to the support means (4).
8. A device according to one of Claims 3 to 7, characterised in that the stamping die (16) is displaceable forward and backwards by means of a hydraulic motor (14).
9. A device according to one of Claims 3 to 8, characterised in that the stamping die (16) is interchangeable.
10. A device according to one of Claims 3 to 9, characterised in that the sensor device (18) has a sensor, particularly an ultrasonic sensor, which responds to hygroscopic material (19) inserted into the hollow section strip.
