Abstract

In an apparatus whereby spacer frames (1) for insulating glass being transported in an essentially vertical position and resting against a supporting wall (2, 6) to a receiving station, may be transferred on a carrier (20), in the area of the receiving station (5) in the supporting wall (6) a plurality of lifting elements (14) is provided, which may be moved upwards in slots (13) to raise the spacer frames (1). To be able to transfer a spacer frame (1) to the carrier (20) for spacer frames (1) located opposite the receiving station (5), the distance between the free ends (30) of the beams (21) of the carrier (20) facing the supporting wall (6) provided in the receiving station (5) and the supporting wall (6) may be reduced for example by the forward tilting of the supporting wall (6). When the supporting wall (6) is tilted forward, the free ends (30) of the beams (21) of the carrier (20) engage two openings (17) in the supporting wall (6) and one spacer frame (1) is transferred to the carrier 20.

Description

Die Erfindung betrifft eine Einrichtung zum Handhaben von Abstandhalterrahmen für Isolierglas, die im wesentlichen lotrecht stehend zu einer Abnahmestelle befördert werden, mit im Bereich der Abnahmestelle in Schlitzen in einer seitlichen Abstützung beispielsweise einer Stützwand, gegen welche die Abstandhalterrahmen anliegen, nach oben bewegbaren Hebegliedern.The invention relates to a device for handling spacer frames for insulating glass, which are conveyed to a take-off point essentially vertically, with in the area of the take-off point in slots in a lateral support, for example a supporting wall, against which the spacer frames bear, upwardly movable lifting members.

Es ist bekannt, Abstandhalterrahmen nach dem Beschichten mit Dicht- bzw. Klebemasse von einer Fördereinrichtung zu einer Abnahmestelle zu bewegen, wobei die Abstandhalter­rahmen während des Transportes an einer seitlichen Ab­stützung anliegen. In der Abnahmestelle werden die Ab­standhalterrahmen von Hebegliedern erfaßt, angehoben und beispielsweise an einen Hängeförderer weitergegeben, oder von einem solchen übernommen.It is known to move spacer frames after coating with sealing or adhesive from a conveyor to a removal point, the spacer frames abutting a lateral support during transport. In the take-off point, the spacer frames are picked up by lifting members, raised and, for example, passed on to a hanging conveyor, or taken over by one.

Auch nach dem Verschweißen der freien Enden von zu Ab­standhalterrahmen gebogenen Hohlprofilleisten müssen die Abstandhalterrahmen oft von einem Linearförderer mit dem sie im wesentlichen stehend gefördert werden, abgenommen und der weiteren Behandlung (Beschichtung mit Kleb- bzw. Dichtmittel oder Fallen der Abstandhalterrahmen mit Trok­kenmittel) zugeführt werden.Even after the free ends of the hollow profile strips bent into spacer frames have been welded together, the spacer frames often have to be removed by a linear conveyor with which they are essentially conveyed upright and fed to further treatment (coating with adhesive or sealant or trapping the spacer frames with drying agent) .

Problematisch bei der bekannten Einrichtung ist es, daß die Abstandhalterrahmen am Hängeförderer mit verhältnis­mäßig großem Abstand voneinander hängen, so daß diese viel Raum benötigen.The problem with the known device is that the spacer frames hang on the overhead conveyor at a relatively large distance from one another, so that they require a lot of space.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrich­tung der eingangs genannten Gattung anzugeben, mit der beispielsweise aus einer Schweißvorrichtung, in der zu Abstandhalterrahmen gebogene Hohlprofilleisten an ihren freien Enden zu einem geschlossenen Abstandhalterrahmen verschweißt werden, herangeförderte Abstandhalterrahmen möglichst raumsparend zwischengestapelt werden können, um sie dann einer weiteren Behandlung, z.B. einer Rahmenbe­schichtungsanlage oder einer Vorrichtung zum Füllen von Abstandhalterrahmen mit hygroskopischem Material (Moleku­larsieb) zuzuführen.The invention has for its object to provide a device of the type mentioned, with which, for example, from a welding device, in which hollow profile strips bent into spacer frames are welded at their free ends to form a closed spacer frame can be stacked as space-saving as possible in order to then feed them to a further treatment, for example a frame coating system or a device for filling spacer frames with hygroscopic material (molecular sieve).

Eine Vorrichtung zum Biegen von Hohlprofilleisten zu Ab­standhalterrahmen ist aus der DE-PS 32 23 881 bekannt.A device for bending hollow profile strips to spacer frames is known from DE-PS 32 23 881.

Eine Vorrichtung zum Stumpfverschweißen von Hohlprofil­leisten ist aus der EP-A1-192 921 bekannt.A device for butt welding hollow profile strips is known from EP-A1-192 921.

Eine Vorrichtung zum Beschichten von Abstandhalterrahmen mit Klebe- bzw. Dichtmaterial ist in der DE-PS 29 03 649 beschrieben.A device for coating spacer frames with adhesive or sealing material is described in DE-PS 29 03 649.

Eine Vorrichtung zum Füllen von zu Abstandhalterrahmen gebogenen Hohlprofilleisten mit hygroskopischem Material ist in der DE-OS 32 24 862 geoffenbart.A device for filling hollow profile strips bent to form spacer frames with hygroscopic material is disclosed in DE-OS 32 24 862.

Die oben geschilderte Aufgabe wird erfindungsgemäß da­durch gelöst, daß der Abnahmestelle gegenüber ein Träger für Abstandhalterrahmen mit wenigstens zwei im wesentli­chen horizontalen Balken, die zueinander parallel ausge­richtet sind, vorgesehen ist, und daß die seitliche Ab­stützung, insbesondere die Stützwand, zum Übergeben eines von den Hebegliedern an der seitlichen Abstützung insbe­sondere der Stützwand hochgehobenen Abstandhalterrahmens auf die Balken, um eine untere, horizontale, zur Förder­richtung parallele Achse auf den Träger zukippbar ist.The above-described object is achieved according to the invention in that the removal point is provided with a support for spacer frames with at least two essentially horizontal beams, which are aligned parallel to one another, and in that the lateral support, in particular the support wall, for transferring one of the lifting members on the lateral support, in particular the support wall, the spacer frame is lifted onto the beams, so that a lower, horizontal axis parallel to the conveying direction can be tilted towards the support.

Mit der erfindungsgemäßen Einrichtung können die von den Hebegliedern entlang der Stützwand hochgehobenen Abstand­halterrahmen problemlos auf die Balken des Trägers aufge­legt werden, so daß sie an diesen hängen, wobei sie von den Balken des Trägers über ihre oberen horizontalen Schenkel gehalten sind. Die erfindungsgemäße Vorrichtung bietet noch den Vorteil, daß es nicht notwendig ist, die Abstandhalterrahmen auf dem Träger nachzuschieben, damit weitere Abstandhalterrahmen aufgelegt werden können, son­dern die am Träger hängenden Abstandhalterrahmen werden jeweils beim Ansetzen eines weiteren Abstandhalterrahmens auf den Träger selbsttätig nachgeschoben.With the device according to the invention, the spacer frames lifted up by the lifting members along the supporting wall can easily be placed on the beams of the carrier, so that they hang on them, being held by the beams of the carrier via their upper horizontal legs. The device according to the invention also has the advantage that it is not necessary to Push spacer frames onto the carrier so that further spacer frames can be placed on them, but the spacer frames hanging on the carrier are automatically pushed each time a further spacer frame is attached to the carrier.

Von Bedeutung ist eine Ausführungsform der erfindungsge­mäßen Einrichtung, die dadurch gekennzeichnet ist, daß der am unteren Rand der Stützwand vorgesehenen Förderein­richtung eine Einrichtung zum Erfassen der Länge des ho­rizontalen Schenkels des umzusetzenden Abstandhalterrah­mens zugeordnet ist, welche die Fördereinrichtung still­setzt, wenn der Abstandhalterrahmen bezüglich der Hebe­glieder symmetrisch ausgerichtet ist. Auf diese Weise wird gewährleistet, daß die Abstandhalterrahmen auf den Träger symmetrisch aufgesetzt werden, so daß auch sehr breite Abstandhalterrahmen nicht das Gleichgewicht ver­lieren und schräg am Träger hängenbleiben.Of importance is an embodiment of the device according to the invention, which is characterized in that the conveyor provided at the lower edge of the supporting wall is assigned a device for detecting the length of the horizontal leg of the spacer frame to be implemented, which stops the conveyor when the spacer frame is symmetrical with respect to the lifting members is aligned. This ensures that the spacer frames are placed symmetrically on the carrier, so that even very wide spacer frames do not lose their balance and get caught on the carrier at an angle.

Weitere Merkmale und Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen und der nachstehenden Be­schreibung der in den Zeichnungen gezeigten Ausführungs­form. Es zeigt: Fig. 1 schaubildlich eine erfindungsgemä­ße Einrichtung und Fig. 2 eine Greifvorrichtung zum Ab­nehmen von am Träger hängenden Abstandhalterrahmen.Further features and details of the invention emerge from the subclaims and the following description of the embodiment shown in the drawings. 1 shows a device according to the invention and FIG. 2 shows a gripping device for removing spacer frames hanging on the carrier.

Bei der in Fig. 1 gezeigten Einrichtung werden die Ab­standhalterrahmen 1 mit ihren nach oben ragenden Teilen gegen eine Stützwand 2 anliegend von einem Förderband 3 in Richtung des Pfeiles 4 zu einer Abnahmestelle 5 trans­portiert.In the device shown in FIG. 1, the spacer frames 1, with their parts projecting upwards, are transported against a support wall 2 by a conveyor belt 3 in the direction of the arrow 4 to a removal point 5.

Die Stützwand 6 im Bereich der Abnahmestelle 5 ist über Holme 7 im Maschinengestell 8 in Schwenklagern 9 um eine Achse 10, die zur Förderrichtung 4 parallel ausgerichtet ist, in Richtung des Doppelpfeiles 11, aus der in Fig. 1 in vollen Linien eingezeichneten Stellung in die in Fig. 1 strichliert eingezeichnete Lage verschwenkbar. Zur ver­ schwenkung der Stützwand 6 ist ein nicht gezeigter, am Maschinengestell 8 abgestützter und an der Stützwand 6 angreifender Druckmittelmotor vorgesehen.The support wall 6 in the area of the take-off point 5 is via bars 7 in the machine frame 8 in pivot bearings 9 about an axis 10 which is aligned parallel to the conveying direction 4 in the direction of the double arrow 11, from the position shown in full lines in FIG in Fig. 1 dashed position pivotable. For ver pivoting of the support wall 6, a pressure medium motor, not shown, supported on the machine frame 8 and engaging on the support wall 6 is provided.

Auch die Stützwand 6 besitzt an ihrem unteren Ende eine Fördereinrichtung (Förderband) 12.The support wall 6 also has a conveyor device (conveyor belt) 12 at its lower end.

In der Stützwand 6 sind zwei im wesentlichen vertikale Schlitze 13 vorgesehen. Diese Schlitze werden von Hebe­gliedern 14 durchgriffen, wobei die Hebeglieder 14 dazu dienen, einen Abstandhalterrahmen 1 an seinem oberen ho­rizontalen Schenkel 15 zu erfassen und entlang der Stütz­wand 6 nach oben zu bewegen.Two essentially vertical slots 13 are provided in the support wall 6. These slots are penetrated by lifting members 14, the lifting members 14 serving to grip a spacer frame 1 on its upper horizontal leg 15 and to move it upward along the support wall 6.

Um das Heranfördern von Abstandhalterrahmen 1 in die Ab­nahmestelle 5 durch die Hebeglieder 14 nicht zu behin­dern, sind diese so geführt, daß sie im Bereich der unte­ren Enden 16 der Schlitze die Stützwand 6 nicht mehr nach vorne überragen. Dies kann in einfacher Weise dadurch er­reicht werden, daß die Umlenkrollen für die Hebeglieder 14 tragende und antreibende Endlosglieder (z.B. Ketten), etwas oberhalb des unteren Randes des Stützwand 6 ange­ordnet sind.In order not to hinder the advancement of spacer frame 1 into the take-off point 5 by the lifting members 14, these are guided such that they no longer protrude beyond the support wall 6 in the region of the lower ends 16 of the slots. This can be achieved in a simple manner in that the deflecting rollers for the endless links (e.g. chains) supporting and driving the lifting links 14 are arranged somewhat above the lower edge of the supporting wall 6.

Die Hebeglieder 14 heben den Abstandhalterrahmen 1 so weit an, daß sein oberer horizontaler Schenkel 15 ober­halb von in der Stützwand 6 vorgesehenen Öffnungen 17 an­geordnet ist.The lifting members 14 raise the spacer frame 1 so far that its upper horizontal leg 15 is arranged above openings 17 provided in the support wall 6.

Die Fördereinrichtung 12 am unteren Ende der Stützwand 6 wird so gesteuert, daß ein in die Abnahmestelle 5 trans­portierter Abstandhalterrahmen 1 genau symmetrisch zu den beiden Hebegliedern 14 angehalten wird. Um ein Rutschen des Abstandhalterrahmens 1 am Förderband 12 insbesondere während der Bremsphase zu vermeiden, ist dem Förderband 12 eine Andrückrolle 18 zugeordnet, die aus einer Ruhela­ge (siehe Fig. 1), in der sie hinter der Stützwand 6 an­geordnet ist, vorgeschwenkt werden kann (Pfeil 19) und von oben gegen den auf der Fördereinrichtung 12 anliegen­den Schenkel des Abstandhalterrahmens 1 anliegt, so daß der nötige Reibungsschluß zwischen Förderband 12 und Rah­menschenkel gewährleistet ist. Zur Zentrierung der Ab­standhalterrahmen 1 gegenüber den Hebegliedern 14 sind Einrichtungen vorgesehen, welche die Länge des unteren horizontalen Schenkels des Abstandhalterrahmens 1 erfas­sen (z.B. eine auf die nach oben ragenden Schenkel des Abstandhalterrahmens 1 ansprechende Lichtschranke in Kom­bination mit der vorgegebenen Fördergeschwindigkeit), wo­bei dann eine weitere Lichtschranke vorgesehen ist, die nach dem Passieren des ersten nach oben ragenden Schen­kels des Abstandhalterrahmens 1 das Förderband 12 still­setzt, nachdem der Abstandhalterrahmen noch um die halbe Länge des horizontalen Schenkels weiterbewegt wurde, so daß der Abstandhalterrahmen zu den Hebegliedern 14 symme­trisch angeordnet ist.The conveyor 12 at the lower end of the support wall 6 is controlled so that a spacer frame 1 transported into the removal point 5 is stopped exactly symmetrically to the two lifting members 14. In order to prevent the spacer frame 1 from slipping on the conveyor belt 12, in particular during the braking phase, the conveyor belt 12 is assigned a pressure roller 18 which can be swiveled forward from a rest position (see FIG. 1) in which it is arranged behind the support wall 6 ( Arrow 19) and from above against the leg of the spacer frame 1 resting on the conveyor 12 so that the necessary frictional engagement between the conveyor belt 12 and the frame leg is ensured. For centering the spacer frame 1 with respect to the lifting members 14, devices are provided which detect the length of the lower horizontal leg of the spacer frame 1 (for example a light barrier responding to the upwardly projecting leg of the spacer frame 1 in combination with the predetermined conveying speed), with a further one then Light barrier is provided, which stops the conveyor belt 12 after passing the first upwardly projecting leg of the spacer frame 1 after the spacer frame has been moved by half the length of the horizontal leg, so that the spacer frame is arranged symmetrically to the lifting members 14.

Der Abnahmestelle 5 gegenüberliegend ist ein Träger 20 vorgesehen. Der Träger 20 weist zwei horizontale Balken 21, auf, die am oberen Ende eines Turms 22 um eine verti­kale Achse 23 von einem Antriebsmotor 24 angetrieben, verdrehbar sind. Der die Balken 21 tragende Turm 22 ist auf einem Fahrgestell 25 über vier Rollen 26 auf Lauf­schienen 27 eines Sockels 28, der über Füße am Boden auf­gestellt ist, in Richtung des Doppelpfeiles 29, d.h. quer zur Förderebene der Abstandhalterrahmen 1 verfahrbar. Zur Bewegung des Turms 22 und damit des Trägers 20 ist ein nicht näher gezeigter Druckmittelmotor vorgesehen.A carrier 20 is provided opposite the take-off point 5. The carrier 20 has two horizontal beams 21, which are rotatable at the upper end of a tower 22 about a vertical axis 23 by a drive motor 24. The tower 22 carrying the beams 21 is on a chassis 25 via four rollers 26 on rails 27 of a base 28, which is set up on the floor by feet, in the direction of the double arrow 29, i.e. The spacer frame 1 can be moved transversely to the conveying plane. A pressure medium motor, not shown, is provided for moving the tower 22 and thus the carrier 20.

Die horizontalen Balken 21 des Trägers 20 erstrecken sich bis in die Nähe der Stützwand 6 und sind so angeordnet, daß sie bei in der strichlierten Lage vorgekippte Stütz­wand 6 mit ihren freien Enden 30 in die Öffnungen 17 in der Stützwand 6 eingreifen.The horizontal bars 21 of the support 20 extend into the vicinity of the support wall 6 and are arranged such that they engage with their free ends 30 in the openings 17 in the support wall 6 when the support wall 6 is tilted in the dashed position.

Durch Absenken der Hebeglieder 14 kann dann ein vorher über die Öffnungen 17 hochgehobener Abstandhalterrahmen 1 auf die Balken 21 übergeben werden.By lowering the lifting members 14, a spacer frame 1 previously raised via the openings 17 can then be transferred to the beams 21.

Beim Vorkippen der Stützwand 6 in die in Fig. 1 strich­liert eingezeichnete Lage werden gleichzeitig allenfalls bereits auf den Balken 21 hängende Abstandhalterrahmen 1 entlang der Balken 21 in Richtung des Turmes 22 des Trä­gers 20 verschoben.When the support wall 6 is tilted forward into the position shown in broken lines in FIG. 1, spacer frames 1 which are already hanging on the beam 21 are at the same time displaced along the beam 21 in the direction of the tower 22 of the support 20.

Um die Abstandhalterrahmen 1 zu schonen, können die Ober­seiten der Balken 21 mit leistenartigen Auflagern aus Gummi oder Kunststoffprofilen ausgestattet sein.In order to protect the spacer frame 1, the upper sides of the beams 21 can be equipped with strip-like supports made of rubber or plastic profiles.

Wenn die eine Hälfte der Balken 21 zur Gänze mit Abstand­halterrahmen bestückt ist, wird das weitere Aufschieben von Abstandhalterrahmen 1 auf die Balken 21 unterbrochen, was beispielsweise durch einen im Bereich der Mitte der Balken 21 vorgesehenen Schalter ausgelöst werden kann und die Balken 21 werden um die Achse 23 durch Betätigung des Motors 24 verdreht, so daß ihre nicht mit Abstandhalter­rahmen 1 beladene Hälfte der Abnahmestelle 5 (Stützwand 6) zugekehrt ist und erneut Abstandhalterrahmen 1 auf die Balken 21 aufgelegt werden können.If one half of the bars 21 is fully equipped with spacer frames, the further pushing of spacer frames 1 onto the bars 21 is interrupted, which can be triggered, for example, by a switch provided in the area of the middle of the bars 21 and the bars 21 are moved around Axis 23 rotated by actuating the motor 24 so that its half not loaded with spacer frame 1 faces the take-off point 5 (supporting wall 6) and spacer frame 1 can be placed on the beams 21 again.

Um die am Träger 20 hängenden Abstandhalterrahmen abneh­men und einer weiteren Bearbeitung zuführen zu können, ist die in Fig. 2 gezeigt Greifvorrichtung 40 vorgese­hen.The gripping device 40 shown in FIG. 2 is provided in order to be able to remove the spacer frames hanging on the carrier 20 and to carry them out for further processing.

Die Greifvorrichtung 40 umfaßt ein Fahrgestell 41 das über möbelrollenartige Räder 42 in beliebigen Richtungen verfahr- und verdrehbar ist. Am Fahrgestell 41 ist nach oben ragend eine Säule 43 befestigt, die an ihrem oberen Ende 44 mit einer sich horizontal erstreckenden Zinke 45 verbunden ist. Die Zinke 45 ist an ihrer Unterseite mit einer leistenförmigen Auflage 46 aus Gummi oder Kunst­stoff ausgestattet.The gripping device 40 comprises a chassis 41 which can be moved and rotated in any direction via furniture roller-like wheels 42. A column 43 is attached to the chassis 41, which projects upwards and is connected at its upper end 44 to a horizontally extending tine 45. The tine 45 is equipped on its underside with a strip-shaped support 46 made of rubber or plastic.

Die Greifvorrichtung 40 umfaßt weiters zwei Zinken 47, die über eine Führungshülse 48 entlang der Säule 43 in Richtung des Doppelpfeiles 49 auf- und abverschiebbar ist. Zur Betätigung der Hülse 48 und damit der Zinken 47 ist ein Handhebel 50 mit Kniehebelmechanismus vorgesehen, der einerseits an der Hülse 48 und anderseits an der Säu­le 43 angreift. Die Hülse 48 ist an der Säule 43 über Führungsrollenpaare 51 und 52 geführt.The gripping device 40 further comprises two prongs 47 which can be moved up and down in the direction of the double arrow 49 via a guide sleeve 48 along the column 43. To actuate the sleeve 48 and thus the tines 47, a hand lever 50 with a toggle mechanism is provided which engages on the sleeve 48 on the one hand and on the column 43 on the other hand. The sleeve 48 is guided on the column 43 via pairs of guide rollers 51 and 52.

Die Höhe der Zinke 45 der Greifvorrichtung 40 ist so ge­wählt, daß die Zinke 45 etwas höher angeordnet ist, als die obere Außenseite von auf dem Träger 20 hängenden Ab­standhalterrahmen. Durch Betätigen des Handhebels 50 wer­den die Zinken 47 der Greifvorrichtung 40 angehoben und heben dabei die am Träger 20 d.h. an dessen Balken 21 hängenden Abstandhalterrahmen 1 von diesen ab und klemmen sie zwischen sich und der oberen Zinke 45. Nun kann die Greifvorrichtung 40 aus der Lage, in der sie die Abstand­halterrahmen 1 vom Träger 20 übernommen hat (in dieser Lage sind die Zinken 45 und 47 zwischen die Balken 21 bzw. ober diesen angeordnet), auf dem Fahrgestell 41 zu einer weiteren Station bewegt werden. Hiezu ist am Fahr­gestell 41 ein Handgriff 53 vorgesehen, der das Manövrie­ren der Greifvorrichtung 20 erleichtert.The height of the tine 45 of the gripping device 40 is selected such that the tine 45 is arranged somewhat higher than the upper outside of spacer frames hanging on the carrier 20. By actuating the hand lever 50, the prongs 47 of the gripping device 40 are raised and thereby lift those on the carrier 20, i.e. on the beam 21 hanging spacer frame 1 from them and clamp them between themselves and the upper tine 45. Now the gripping device 40 can from the position in which it has taken over the spacer frame 1 from the carrier 20 (in this position, the tines 45 and 47 arranged between the beams 21 or above these), are moved on the chassis 41 to a further station. For this purpose, a handle 53 is provided on the chassis 41, which facilitates the maneuvering of the gripping device 20.
