Description

Die Erfindung betrifft eine Vorrichtung zum Ansetzen von Abstandhalterrahmen auf Glasscheiben im Zuge der Herstellung von Isolierglasscheiben mit einer, im wesentlichen lotrecht stehenden Stützwand für die Glasscheiben und einer vor der Stützwand angeordneten, rahmenartigen Halterung für die Abstandhalterrahmen, wobei an der rahmenartigen Hatterung Klemmeinrichtungen und zurückziehbare Anlagestifte für den anzusetzenden Abstandhalterrahmen angeordnet sind und wobei der obere, horizontale Schenkel der rahmenartigen Halterung parallel zur Stützwand auf-und abverschiebbar ist.The invention relates to a device for attaching spacer frames to glass panes in the course of the production of insulating glass panes with a substantially vertical support wall for the glass panes and a frame-like holder for the spacer frames arranged in front of the support wall, with clamping devices and retractable contact pins on the frame-like hatch are arranged for the spacer frame to be attached and the upper, horizontal leg of the frame-like holder can be moved up and down parallel to the supporting wall.

Eine derartige Vorrichtung ist beispielsweise aus der DE-C 32 23 848 bekannt. Die Abstandhalterrahmen werden in die bekannte Vorrichtung entweder händisch oder mit Hilfe einer Vorrichtung zum Umsetzen beschichteter Abstandhalterrahmen von einem Förderer, auf welchem die Abstandhalterrahmen auf Haken frei hängend, zu einer Abnahmestelle befördert werden, in die Vorrichtung zum Ansetzen von Abstandhalterrahmen eingelegt. Eine Vorrichtung zum Umsetzen beschichteter Abstandhalterrahmen ist aus der DE-C 32 22 903 bekannt.Such a device is known for example from DE-C 32 23 848. The spacer frames are placed in the known device either by hand or with the aid of a device for converting coated spacer frames from a conveyor, on which the spacer frames are freely suspended on hooks and transported to a removal point, in the device for attaching spacer frames. A device for implementing coated spacer frames is known from DE-C 32 22 903.

Nachteilig bei der bekannten Vorrichtung zum Umsetzen von Abstandhalterrahmen von einem Förderer in eine Vorrichtung zum Ansetzen von Abstandhalterrahmen auf Glasscheiben ist es, daß sie viel Platz beansprucht und insbesondere sehr hoch gebaut werden muß.A disadvantage of the known device for moving spacer frames from a conveyor into a device for attaching spacer frames to glass panes is that it takes up a lot of space and in particular has to be built very high.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung, wie sie aus der DE-C 32 23 848 oder der bekanntgemachten österreichischen Patentanmeldung A 6955/78 bekannt ist, derart weiterzubilden, daß eine gesonderte Umsetzvorrichtung für die Abstandhalterrahmen nicht mehr benötigt wird.The invention has for its object to develop a device of the type mentioned, as known from DE-C 32 23 848 or the known Austrian patent application A 6955/78, such that a separate conversion device for the spacer frame is no longer required .

Erfindungsgemäß wird dies dadurch erreicht, daß am oberen, horizontalen Schenkel der rahmenartigen Halterung wenigstens zwei Greifer montiert sind, die zwischen einer dem Ende eines Hängeförderers für Abstandhalterrahmen zugeordneten Abnahmestellung und einer Abgabestellung, in der die Abstandhalterrahmen an die Anlagestifte der rahmenartigen Halterung anliegend abgesetzt werden, hin- und herbeweglich sind.According to the invention, this is achieved in that at least two grippers are mounted on the upper, horizontal leg of the frame-like holder, which grips between a removal position assigned to the end of a hanging conveyor for spacer frames and a delivery position in which the spacer frames are placed against the contact pins of the frame-like holder. are reciprocating.

Die erfindungsgemäße Lösung zeichnet sich durch überraschende Einfachheit aus, da derhorizontal verlaufende, auf- und abverstellbare obere Schenkel der rahmenartigen Halterung, durch welche die Abstandhalterrahmen beim Ansetzen derselben an die in der Ansetzvorrichtung stehende Glasscheibe genau ausgerichtet gehalten werden, als Träger für die Greifer dient, welche die Abstandhalterrahmen vom Hängeförderer abnehmen.The solution according to the invention is characterized by surprising simplicity, since the horizontally extending, up and down adjustable upper leg of the frame-like holder, by means of which the spacer frames are kept precisely aligned when they are attached to the glass pane in the attachment device, serves as a carrier for the grippers, which remove the spacer frames from the overhead conveyor.

In einer praktischen Ausführungsform kann vorgesehen sein, daß die Greifer wenigstens zwei miteinander gelenkig verbundene Arme aufweisen. Durch diese Ausführungsform ist der Vertikalhub, den der horizontal verlaufende Schenkel der rahmenartigen Halterung beim Umsetzen der Abstandhalterrahmen vom Horizontalförderer in die Ansetzvorrichtung ausführen muß, verkleinert.In a practical embodiment it can be provided that the grippers have at least two arms articulated to one another. This embodiment reduces the vertical stroke that the horizontally extending leg of the frame-like holder has to carry out when the spacer frame is moved from the horizontal conveyor into the attachment device.

Ähnlich, wie dies aus der DE-C 32 22 903 bekannt ist, kann im Rahmen der Erfindung vorgesehen sein, daß am freien Ende jedes Greifers oder des äußeren Armes desselben eine Ringklaue vorgesehen ist, wobei wenigstens ein Ringteil gegenüber dem anderen zum Öffnen und Schließen der Ringklaue verschwenkbar ist.Similarly, as is known from DE-C 32 22 903, it can be provided within the scope of the invention that an annular claw is provided at the free end of each gripper or the outer arm thereof, at least one ring part opposite the other for opening and closing the ring claw is pivotable.

Gemäß einer anderen Ausführungsform ist es möglich, am freien Ende jedes Greifers oder des äußeren Armes desselben eine Klemme zum Erfassen von Abstandhalterrahmen in der Abnahmestellung des Greifers vorzusehen. Diese Ausführungsform hat den Vorteil, daß ein genau gezieltes Einsetzen des Abstandhalterrahmens in die Ansetzvorrichtung möglich ist.According to another embodiment, it is possible to provide a clamp at the free end of each gripper or the outer arm thereof for gripping spacer frames in the removal position of the gripper. This embodiment has the advantage that a precisely targeted insertion of the spacer frame into the attachment device is possible.

Nach einer weiteren Ausführungsform der Erfindung können die Greifer an ihren freien Enden ggf. verschwenkbar befestigte Haken aufweisen.According to a further embodiment of the invention, the grippers can optionally have pivotably attached hooks at their free ends.

Um das Abgeben der Abstandhalterrahmen zu vereinfachen, kann erfindungsgemäß vorgesehen sein, daß die freien Enden der Haken in der unteren Endlage der Greifer im wesentlichen horizontal ausgerichtet sind und unterhalb des Abschnittes der Haken angeordnet sind, über den dieser am Greifer verschwenkbar befestigt ist. Bei dieser besonders einfachen Ausführungsform der Erfindung können die Haken jetzt besonders einfach aus dem in der rahmenartigen Halterung stehenden und gegebenenfalls schon von den Klemmeinrichtungen erfassten Abstandhalterrahmen herausbewegt werden.In order to simplify the delivery of the spacer frames, it can be provided according to the invention that the free ends of the hooks in the lower end position of the grippers are aligned essentially horizontally and are arranged below the section of the hook via which the hook is pivotably attached to the gripper. In this particularly simple embodiment of the invention, the hooks can now be moved particularly easily out of the spacer frame which is in the frame-like holder and, if appropriate, has already been gripped by the clamping devices.

In einer praktischen Ausführungsform der Erfindung kann vorgesehen sein, daß die freien Enden der Haken in der unteren Endlage der Greifer außer Eingriff mit den an den Anlagestiften anliegenden Abstandhalterrahmen sind. Bei dieser Ausführungsform können die Haken von den Abstandhalterrahmen unbehindert nach oben verschwenkt werden.In a practical embodiment of the invention it can be provided that the free ends of the hooks in the lower end position of the grippers are out of engagement with the spacer frames resting on the contact pins. In this embodiment, the hooks can be pivoted freely upwards by the spacer frames.

Gemäß einer Ausführungsform der Erfindung ist es möglich, daß am unteren horizontalen Schenkel der rahmenartigen Halterung wenigstens ein Hebeglied zum Anheben des unteren horizontalen Rahmenschenkels eines Abstandhalterrahmens vorgesehen sind. Diese Ausführungsform hat den Vorteil, daß ein genau gezieltes Einsetzen auch des unteren, horizontalen Schenkels des Abstandhalterrahmens in die Ansetzvorrichtung möglich ist, ohne daß die Greifer diesen sehr hoch heben müssen.According to one embodiment of the invention, it is possible for at least one lifting member for lifting the lower horizontal frame leg of a spacer frame to be provided on the lower horizontal leg of the frame-like holder. This embodiment has the advantage that a precisely targeted insertion of the lower, horizontal leg of the spacer frame into the attachment device is possible without the grippers having to lift it very high.

Die erfindungsgemäße Vorrichtung zum Ansetzen von Abstandhalterrahmen auf Glasscheiben besitzt bei der in den Figuren 1 und 2 gezeigten Ausführungsform eine Stützwand 1, die über Füße 2 am Boden steht. Die Stützwand 1 ist gegenüber der Vertikalen geringfügig, beispielsweise um etwa 5°, nach hinten geneigt und besitzt auf ihrer Vorderseite mehrere, um im wesentlichen vertikale Achsen frei drehbare Stützrollen 3. Am unteren Rand der Stützwand 1 sind um im wesentlichen horizontale Achsen drehbar antreibbare Förderrollen 4 vorgesehen. Die Förderrollen 4 dienen zum Herantransportieren von Glasscheiben 5 in eine definierte Endlage in der Vorrichtung.In the embodiment shown in FIGS. 1 and 2, the device according to the invention for attaching spacer frames to glass panes has a support wall 1 which stands on the floor via feet 2. The support wall 1 is slightly inclined to the vertical, for example by approximately 5 ° , and has on its front side a plurality of support rollers 3 which can be freely rotated about substantially vertical axes 4 provided. The conveyor rollers 4 are used to transport glass panes 5 into a defined end position in the device.

Im Abstand vor der Stützwand 1 ist eine parallel zur Stützwand 1 ausgerichtete, rahmenartige Halterung 8 vorgesehen, die zwei im wesentlichen vertikale Schenkel 9, einen unteren, horizontalen Schenkel 10 und einen oberen, horizontalen Schenkel 11 aufweist. Die rahmenartige Halterung 8 ist über Druckmittelzylinder 12 auf die Stützwand 1 zu und von dieser weg bewegbar (Pfeil 13). Anstelle der Druckmittelzylinder 12 können zur Bewegung der rahmenartigen Halterung 8 gegenüber der Stützwand 1 auch Zahnstangen-Zahnradgetriebe vorgesehen sein.At a distance from the support wall 1, a frame-like holder 8 is provided which is aligned parallel to the support wall 1 and has two essentially vertical legs 9, a lower, horizontal leg 10 and an upper, horizontal leg 11. The frame-like holder 8 can be moved towards and away from the support wall 1 via pressure medium cylinders 12 (arrow 13). Instead of the pressure medium cylinders 12, rack-and-pinion gear transmissions can also be provided for moving the frame-like holder 8 with respect to the support wall 1.

Der obere, horizontale Schenkel 11 der rahmenartigen Halterung 8 ist in Richtung des Doppelpfeiles 14 auf und ab verschiebbar. Die Verschiebbarkeit des oberen, horizontalen Schenkels 11 dient zur Anpassung der Höhe der rahmenartigen Halterung 8 an die Abmessungen des anzusetzenden Abstandhalterrahmens. Zusätzlich kann einer der vertikalen Schenkel 9, insbesondere der, bezogen auf die Richtung, in der Glastafel 5 in die Vorrichtung gefördert werden, hintere Schenkel 9 in Förderrichtung, d. h. senkrecht zur Bildebene von Fig. 1 verstellbar sein, damit die horizontale Abmessung der Halterung 8 an die Länge eines anzusetzenden Abstandhalterrahmens 18 angepaßt werden kann.The upper, horizontal leg 11 of the frame-like holder 8 can be moved up and down in the direction of the double arrow 14. The displaceability of the upper, horizontal leg 11 serves to adapt the height of the frame-like holder 8 to the dimensions of the spacer frame to be attached. In addition, one of the vertical legs 9, in particular the, based on the direction, in the glass sheet 5 can be conveyed into the device, rear legs 9 in the conveying direction, i. H. 1 so that the horizontal dimension of the holder 8 can be adapted to the length of a spacer frame 18 to be attached.

An der rahmenartigen Halterung 8 sind sowohl an den beiden horizontalen Schenkeln 10 und 11 als auch wenigstens am auslaufseitig angeordneten vertikalen Schenkel 9 - vorzugsweise auch am einlaufseitigen Schenkel 9, insbesondere wenn dieser verstellbar ist - Anlagestifte 15 und Klemmeinrichtungen 16 vorgesehen. Die Anlagestifte 15 und die Klemmeinrichtungen 16 (es sind nur die bei dieser Ausführungsform an der Halterung 8 befestigten Anschläge derselben gezeigt) können, wie dies aus der DE-C 32 23 848 oder der bekanntgemachten österreichischen Patentanmeldung A 6955/78 bekannt ist, ausgebildet sein.Contact pins 15 and clamping devices 16 are provided on the frame-like holder 8 both on the two horizontal legs 10 and 11 and at least on the vertical leg 9 arranged on the outlet side - preferably also on the inlet side leg 9, in particular if this is adjustable. The contact pins 15 and the clamping devices 16 (only the stops attached to the holder 8 in this embodiment are shown in this embodiment) can be designed, as is known from DE-C 32 23 848 or the known Austrian patent application A 6955/78 .

Hinsichtlich der Arbeitsweise der soeben beschriebenen Vorrichtung zum Ansetzen von Abstandhalterrahmen an eine Glasscheibe wird auf die DE-C 32 23 848 verwiesen.Regarding the operation of the device just described for attaching spacer frames to a glass pane, reference is made to DE-C 32 23 848.

Am oberen, horizontalen Schenkel 11 der rahmenartigen Halterung 8 sind wenigstens zwei Greifer 17 vorgesehen, die zwischen einer Stellung, in der sie beschichtete Abstandhalterrahmen 18 von einem Horizontalhängeförderer 19 abnehmen ("Abnahmestellung", Figur 1) und einer Stellung, in der sie den zuvor abgenommenen Abstandhalterrahmen 18 an den Anlagestiften 15 der rahmenartigen Halterung 8 anliegend in die Vorrichtung zum Ansetzen der Abstandhalterrahmen auf Glasscheiben 5 abgeben ("Abgabestellung", Figur 2), bewegbar sind.On the upper, horizontal leg 11 of the frame-like holder 8, at least two grippers 17 are provided, which between a position in which they remove coated spacer frames 18 from a horizontal hanging conveyor 19 ("removal position", FIG. 1) and a position in which they previously remove the removed spacer frame 18 against the contact pins 15 of the frame-like holder 8 into the device for attaching the spacer frame to glass panes 5 (“delivery position”, FIG. 2).

Im in den Figuren 1 und 2 gezeigten Ausführungsbeispiel weisen die Greifer 17 zwei miteinander gelenkig verbundene Arme 20, 21 auf, wobei die Arme 20 auf einer Welle 22 montiert sind, die parallel zum oberen, horizontalen Schenkel 11 der rahmenartigen Halterung 8 verläuft und die mit Hilfe eines nicht gezeigten Antriebes zum Verschwenken der Arme 20 und damit der Greifer 17 selbst zwischen der Abnahme- und der Abgabestellung in Richtung des Doppelpfeiles 23 verdrehbar ist. Der gelenkigen Verbindung 24 zwischen den Armen 20 und 21 der Greifer 17 sind nicht näher gezeigte Antriebe (z. B. Druckmittelmotore oder Stellmotore usw.) zugeordnet, so daß der Arm 21 in Richtung des Doppelpfeiles 25 gegenüber dem Arm 20 verschwenkt werden kann.In the exemplary embodiment shown in FIGS. 1 and 2, the grippers 17 have two arms 20, 21 which are connected to one another in an articulated manner, the arms 20 being mounted on a shaft 22 which runs parallel to the upper, horizontal leg 11 of the frame-like holder 8 and which coexists With the aid of a drive (not shown) for pivoting the arms 20 and thus the gripper 17 itself can be rotated in the direction of the double arrow 23 between the removal and the discharge position. The articulated connection 24 between the arms 20 and 21 of the grippers 17 are associated with drives (not shown in detail, for example, pressure medium motors or servo motors, etc.), so that the arm 21 can be pivoted in the direction of the double arrow 25 relative to the arm 20.

Der Arm 21 trägt an seinem freien Ende eine Ringklaue 26, die im gezeigten Ausführungsbeispiel aus zwei, mit Hilfe von Druckmittelmotoren 27 verschwenkbaren Ringhälften 28 besteht. Es ist auch eine Ausführungsform mit einer starren und einer verschwenkbaren Ringhälfte, wie dies aus der DE-C 32 22 903 bekannt ist, verwendbar.The arm 21 carries at its free end an annular claw 26 which, in the exemplary embodiment shown, consists of two ring halves 28 which can be pivoted with the aid of pressure medium motors 27. An embodiment with a rigid and a pivotable ring half, as is known from DE-C 32 22 903, can also be used.

Wenn ein Abstandhalterahmen 18 vom Hängeförderer 19 abgenommen werden soll, werden die Greifer 17 in eine Stellung gebracht, in der ihre Klauen 26 den am Hängeförderer 19 hängenden Abstandhalterrahmen an seinem oberen, horizontalen Schenkel erfassen (Figur 1). Hiezu werden die Arme 20 und 21 entsprechend betätigt, die Ringklaue 26 geöffnet und der obere, horizontale Balken 11 der rahmenartigen Halterung 8 nach oben bewegt.If a spacer frame 18 is to be removed from the overhead conveyor 19, the grippers 17 are brought into a position in which their claws 26 grip the spacer frame hanging on the overhead conveyor 19 on its upper, horizontal leg (FIG. 1). For this purpose, the arms 20 and 21 are actuated accordingly, the ring claw 26 is opened and the upper, horizontal bar 11 of the frame-like holder 8 is moved upward.

Sobald ein Abstandhalterrahmen 18 von den Greifern 17 erfaßt ist, bewegt sich der obere, horizontalen Schenkel 11 der rahmenartigen Halterung 8 in die Stellung, die er beim Ansetzen eines Abstandhalterrahmens an die Glasscheibe 5 einnehmen muß, also in die der Höhe des Abstandhalterrahmens 18 entsprechende Lage. Gleichzeitig oder auch vorher werden die Greifer 17 in die in Figur 2 gezeigte Stellung bewegt und ihre Ringklauen 26 öffnen sich, wobei insbesondere eine Offnung der dann unteren Ringhälfte 28 erfolgt. Der Abstandhalterrahmen 18 steht dann auf den Klemmbacken der unteren Klemmeinrichtungen 16 auf und lehnt sich nach dem vollständigen Öffnen der Ringklauen 26 an die oberen Anlagestifte 15, die am Balken 11 montiert sind, an. Dann weden die Greifer 17 und insbesondere ihre Ringklauen 26 aus dem Bereich der rahmenartigen Halterung 8 weggeschwenkt und das Ansetzen des Abstandhalterrahmens 18 an die Glasscheibe 5, kann, wie in der DE-C 32 23 848 beschrieben, fortgesetzt werden.As soon as a spacer frame 18 is gripped by the grippers 17, the upper, horizontal leg 11 of the frame-like holder 8 moves into the position which it has to assume when attaching a spacer frame to the glass pane 5, i.e. into the position corresponding to the height of the spacer frame 18 . At the same time or even beforehand, the grippers 17 are moved into the position shown in FIG. 2 and their ring claws 26 open, the lower half of the ring 28 then opening in particular. The spacer frame 18 then stands on the clamping jaws of the lower clamping devices 16 and, after the ring claws 26 have completely opened, is leaning against the upper contact pins 15 which are mounted on the beam 11. Then the grippers 17 and in particular their ring claws 26 are pivoted away from the area of the frame-like holder 8 and the attachment of the spacer frame 18 to the glass pane 5 can be continued as described in DE-C 32 23 848.

Um das Zuführen des Abstandhalterrahmens 18 auf die Klemmbacken der unteren Klemmeinrichtungen 16 zu erleichtern, können diese mit Leiteinrichtungen 29 ausgerüstet sein.In order to facilitate the feeding of the spacer frame 18 onto the clamping jaws of the lower clamping devices 16, these can be equipped with guide devices 29.

Die Greifer 30 der in den Figuren 3 bis 7 gezeigten Ausführungsform sind einstückig ausgebildet, besitzen eine ggf. mehrfach abgewinkelte Form und sind auf der gemein samen Welle 22 drehfest montiert. Zum Verdrehen der Welle 22, die am oberen, horizontalen Schenkel 11 der Halterung 8 gelagert ist, ist ein Druckmittelmotor 31 vorgesehen.The grippers 30 of the embodiment shown in Figures 3 to 7 are integrally formed, have a possibly multiple angled shape and are rotatably mounted on the common shaft 22. A pressure medium motor 31 is provided for rotating the shaft 22, which is mounted on the upper, horizontal leg 11 of the holder 8.

Die Greifer 30 tragen an ihren freien Enden einen Haken 32, der um eine Achse 33 gegenüber dem Greifer 30 verschwenkbar gelagert ist. Der Haken 32 besitzt eine über die Welle 22 hinausragende Verlängerung 34, die über ein Gelenk 36 mit einem Rohrstück 35 verbunden ist. Das Rohrstück 35 besitzt an seinem, dem Gelenk 36 gegenüberliegenden Ende Langschlitze 37, die von einem am Greifer 30 befestigten Stift 38 durchsetzt werden. Im Rohr 35 ist eine Schraubendruckfeder 39 vorgesehen, die einerseits am freien Ende der Verlängerung des Hakens 32 und anderseits am Stift 38 abgestützt ist. Durch die Kraft der Feder 39 wird der Haken 32 sowohl in der in Figur 3 und 5 gezeigten Lage als auch in der in Figur 7 gezeigten, ausgeschwenkten Lage festgehalten, ohne das Anschläge notwendig sind. Die jeweiligen Endlagen des Verschwenkbereiches des Hakens 32 werden durch Anliegen des Stiftes 38 an den dem Ende des Rohres 39 benachbarten Enden der Schlitze 37 definiert.The grippers 30 carry at their free ends a hook 32 which is pivotably mounted about an axis 33 with respect to the gripper 30. The hook 32 has an extension 34 which projects beyond the shaft 22 and is connected to a pipe section 35 via a joint 36. The tube piece 35 has at its end, opposite the joint 36, long slots 37 which are penetrated by a pin 38 fastened to the gripper 30. A helical compression spring 39 is provided in the tube 35, which is supported on the one hand at the free end of the extension of the hook 32 and on the other hand on the pin 38. Due to the force of the spring 39, the hook 32 is held both in the position shown in FIGS. 3 and 5 and in the pivoted-out position shown in FIG. 7, without the need for stops. The respective end positions of the pivoting area of the hook 32 are defined by the pin 38 resting on the ends of the slots 37 adjacent to the end of the tube 39.

Mit Hilfe des Druckmittelzylinders 31 kann der Greifer 30 in Richtung des Pfeiles 40 hochgeschwenkt werden, um einen Abstandhalterrahmen 18 von einem Hängeförderer 19 abzunehmen, wobei gleichzeitig der obere, horizontale Schenkel 11 der rahmenartigen Halterung 8 nach oben bewegt wird. Sobald ein Abstandhalterrahmen 18 vom Hängeförderer 19 abgenommen worden ist, werden die Greifer 30 in Richtung des Pfeiles 41 verschwenkt, so daß die Haken in dem Bereich der Klemmeinrichtungen 16 und der Anlagestifte 15 gelangen.With the aid of the pressure medium cylinder 31, the gripper 30 can be swiveled up in the direction of the arrow 40 in order to remove a spacer frame 18 from a hanging conveyor 19, the upper, horizontal leg 11 of the frame-like holder 8 being moved upwards at the same time. As soon as a spacer frame 18 has been removed from the overhead conveyor 19, the grippers 30 are pivoted in the direction of the arrow 41 so that the hooks reach the area of the clamping devices 16 and the contact pins 15.

Wie insbesondere Figur 4 zeigt, sind die Greifer 30 neben den Anlagestiften 15 angeordnet, wobei zwischen den Greifern 30 und den benachbarten Anlagestiften 15 jeweils eine Klemmeinrichtung 16, die ein hakenartiges Klemmorgan 42 aufweist, angeordnet ist. Die Klemmeinrichtungen 16 können beispielsweise die aus Figur 10 der DE-C 32 23 848 bekannte Bauart mit in Schwenklagern 43 gleitend geführten, durch nicht gezeigte Druckmittelmotore verschwenkbaren Klemmorgane 42 besitzen.As shown in FIG. 4 in particular, the grippers 30 are arranged next to the contact pins 15, a clamping device 16, which has a hook-like clamping member 42, being arranged between the grippers 30 and the adjacent contact pins 15. The clamping devices 16 can, for example, have the type known from FIG. 10 of DE-C 32 23 848 with clamping members 42 which are guided in swivel bearings 43 and can be pivoted by means of pressure medium motors, not shown.

Die Anlagestifte 15 sind bei der in Figur 3 und Figur 4 gezeigten Ausführungsform mit Hilfe eines Parallelogrammtriebes 44 in und aus ihrer in Figur 3 strichliert eingezeichneten Wirkstellung bewegbar, wobei sie über eine Welle 45, die über die Länge des oberen, horizontalen Schenkels 11 der Halterung 8 durchgehend ausgebildet ist, antreibbar sind.In the embodiment shown in FIG. 3 and FIG. 4, the contact pins 15 can be moved in and out of their active position shown in broken lines in FIG 8 is continuous, can be driven.

Das Verschwenken des Hakens 32 an den freien Enden eines Greifers 30 ist in den Figuren 5 bis 7 gezeigt. Der Haken 32 ist drehfest mit einem Betätigungshebel 46 verbunden. Diesem Betätigungshebel sind (vgl. Figuren 3 und 4) zwei Steuerbolzen 47 und 48 zugeordnet, die über einen Träger 49 am Schenkel 11 der rahmenartigen Halterung 8 befestigt sind.The pivoting of the hook 32 at the free ends of a gripper 30 is shown in FIGS. 5 to 7. The hook 32 is rotatably connected to an operating lever 46. This actuating lever (see FIGS. 3 and 4) is assigned two control bolts 47 and 48 which are fastened to the leg 11 of the frame-like holder 8 via a carrier 49.

Sobald sich die Greifer 30 aus der Abnahmestellung (nicht gezeigt) in Richtung des Pfeiles 41 in die Abgabestellung bewegen, gelangt, wie Figur 5 zeigt, der Hebel 46 zwischen die Steuerbolzen 47 und 48 (Figur 5) und dann in Anlage an den Steuerbolzen 47 (Figur 6). In dem Moment, wo der Hebel 46 an den Steuerbolzen 47 in Anlage kommt, nimmt der Haken 32 eine Stellung ein, in der sein freies Ende im wesentlichen horizontal verläuft und der von ihm getragene Abstandhalterrahmen 18 am Anlagestift 15 anliegt. Durch fortgesetztes Verschwenken der Greifer 30 in Richtung des Pfeiles 41 wird der Haken 32 vom am Steuerbolzen 47 anliegenden Hebel 46 verschwenkt, bis er unter der Wirkung der im Rohr 35 vorgesehenen Feder 39 in die in Figur 7 gezeigte Stellung ausschwenkt. Nun ist der Abstandhalterrahmen 18 von den Greifern 30 bzw. ihren Haken 32 frei, liegt an den Anlagestiften 15 an, und steht unten auf den Klemmbacken der Klemmvorrichtungen 16 auf.As soon as the grippers 30 move from the removal position (not shown) in the direction of arrow 41 into the delivery position, as shown in FIG. 5, the lever 46 comes between the control bolts 47 and 48 (FIG. 5) and then in contact with the control bolt 47 (Figure 6). At the moment when the lever 46 comes into contact with the control pin 47, the hook 32 assumes a position in which its free end runs essentially horizontally and the spacer frame 18 which it carries lies against the contact pin 15. By continuously pivoting the grippers 30 in the direction of the arrow 41, the hook 32 is pivoted by the lever 46 resting on the control pin 47 until it swings out into the position shown in FIG. 7 under the action of the spring 39 provided in the tube 35. The spacer frame 18 is now free of the grippers 30 or their hooks 32, abuts the contact pins 15, and stands on the jaws of the clamping devices 16 at the bottom.

Die Klemmvorrichtungen 16 werden nunmehr betätigt, wobei die hakenförmigen Klemmorgane 32 verschwenken und den Abstandhalterrahmen 18 vorzugsweise an allen vier Schenkeln desselben gegen die Klemmbacken der Klemmvorrichtungen 16 drücken. Hierauf werden die Anlagestifte 15 aus dem Bereich des Abstandhalterrahmens 18 wegbewegt (durch Betätigung der Welle 45), so daß der Abstandhalterahmen 18 nun zum Ansetzen an eine Glasscheibe 5 bereit ist.The clamping devices 16 are now actuated, the hook-shaped clamping members 32 pivoting and preferably pressing the spacer frame 18 against the clamping jaws of the clamping devices 16 on all four legs thereof. The contact pins 15 are then moved away from the area of the spacer frame 18 (by actuating the shaft 45), so that the spacer frame 18 is now ready for attachment to a glass pane 5.

Inbesondere bei der in den Figuren 3 bis 7 gezeigten Ausführungsform ist es möglich, nicht die rahmenartige Halterung 8 der an der Stützwand 1 stehenden Glasscheibe 5 anzunähern, sondern es wird die Stützwand 1, die im Maschinengestell quer zur ihrer Ebene (sinngemäß dem Pfeil 13 in Figur 1) beweglich ist, auf die im Maschinengestell quer zu ihrer Ebene nicht verstellbare, rahmenartige Halterung 8 zu vorgeschoben, bis die Glasscheibe 5 in Anlage an den Abstandhalterrahmen 18 bzw. die auf ihm angebrachte Beschichtung aus Kleb- bzw. Dichtmittel anliegt. Das endgültige Andrücken des Abstandhalterrahmens an die Glasscheibe 5 erfolgt ähnlich wie dies in der DE-C 32 23 848, Spalte 7, Zeilen 9 bis 14, beschrieben ist mit Hilfe von Druckmittelzylindern mit vorschiebbaren Druckstiften.In particular in the embodiment shown in FIGS. 3 to 7, it is possible not to approximate the frame-like holder 8 of the glass pane 5 standing on the support wall 1, but rather the support wall 1 which is in the machine frame transversely to its plane (analogously to the arrow 13 in Figure 1) is movable towards the frame-like holder 8 which is not adjustable transversely to its plane in the machine frame until the glass pane 5 abuts the spacer frame 18 or the coating of adhesive or sealant applied to it. The final pressing of the spacer frame onto the glass pane 5 takes place in a manner similar to that described in DE-C 32 23 848, column 7, lines 9 to 14, using pressure medium cylinders with push pins that can be pushed forward.

Nachdem der Abstandhalterrahmen 18 auf die Glasscheibe 5 angesetzt worden ist, wird die Stützwand 1 wieder von der rahmenartigen Halterung 8 wegbewegt. In weiterer Folge werden die Greifer 30 in Richtung des Pfeiles 40 (Figur 3) verschwenkt, wodurch die Haken 32 über ihre Hebel 36, die an den Steuerbolzen 48 anliegen, wieder in ihre in Figur 3 gezeigte Stellung zurückverschwenken und zur Abnahme eines weiteren Abstandhalterrahmens 18 bereit sind.After the spacer frame 18 has been placed on the glass pane 5, the support wall 1 is again moved away from the frame-like holder 8. Subsequently, the grippers 30 are pivoted in the direction of the arrow 40 (FIG. 3), as a result of which the hooks 32 pivot back into their position shown in FIG. 3 via their levers 36, which bear against the control bolts 48, and to remove a further spacer frame 18 to be ready.

Es versteht sich, daß auch bei der in den Figuren 3 bis 7 gezeigten Ausführungsform der obere, horizontale Schenkel 11 der rahmenartigen Halterung 8 der erfindungsgemäßen Vorrichtung in die der Höhe des anzusetzenden Abstandhalterrahmens 18 entsprechende Höhenlage bewegt wird, nachdem ein Abstandhalterrahmen 18 mit Hilfe der Greifer 30 vom Hängeförderer 19 abgenommen worden ist. Die Bewegung des Schenkels 11 der rahmenartigen Halterung 8 kann gleichzeitig mit dem Verschwenken der Greifeinrichtung des Pfeiles 41 erfolgen. Überdies ist es möglich, daß das letzte Stück des Hubes des horizontalen Schenkels 11 der rahmenartigen Halterung 8 in die der Höhe des anzusetzenden Abstandhalterrahmens entsprechende Endlage nach dem Einlegen des Abstandhalterrahmens in die Halterung 8 erfolgt.It is understood that even in the case of the figures 3 to 7 shown embodiment, the upper, horizontal leg 11 of the frame-like holder 8 of the device according to the invention is moved to the height corresponding to the height of the spacer frame 18 to be attached after a spacer frame 18 has been removed from the overhead conveyor 19 with the aid of the grippers 30. The movement of the leg 11 of the frame-like holder 8 can take place simultaneously with the pivoting of the gripping device of the arrow 41. Furthermore, it is possible that the last piece of the stroke of the horizontal leg 11 of the frame-like holder 8 takes place in the end position corresponding to the height of the spacer frame to be attached after the spacer frame has been inserted into the holder 8.

Die Greifer 30 der in Figur 8 gezeigten, erfindungsgemäßen Ausführungsform sind einstückig ausgebildet, besitzen eine ggf. mehrfach abgewinkelte Form und sind auf der gemeinsamen Welle 22 drehfest montiert, wobei zum Verdrehen der Welle 22, die am oberen, horizontalen Schenkel 11 der Halterung 8 gelagert ist, der Druckmittelmotor 31 vorgesehen ist.The grippers 30 of the embodiment according to the invention shown in FIG. 8 are formed in one piece, have an optionally multiple angled shape and are mounted in a rotationally fixed manner on the common shaft 22, the bearings 8 being mounted on the upper, horizontal leg 11 of the holder 8 in order to rotate the shaft 22 is, the pressure medium motor 31 is provided.

Jeder Greifer 30 trägt an seinem freien Ende einen Haken 50, der um eine Achse 51 gegenüber dem Greifer 30 verschwenkbar gelagert ist. Der Haken 50 besitzt eine über die Achse 51 hinausragende Verlängerung 53.Each gripper 30 carries at its free end a hook 50 which is pivotably mounted about an axis 51 with respect to the gripper 30. The hook 50 has an extension 53 projecting beyond the axis 51.

Die Haken 50 sind um die Achse 51 aus der in Figur 8 gezeigten Lage durch einen Druckmittelmotor 52 der an einer Verlängerung 53 des Hakens 50 angreift, nach oben verschwenkbar. Es ist auch möglich, die Haken 50 an einer gemeinsamen Welle zu montieren, die an den freien Enden der Greifer 30 durch einen Druckmittelmotor (ähnlich 52, 53) verschwenkbar gelagert ist.The hooks 50 can be pivoted upwards about the axis 51 from the position shown in FIG. 8 by a pressure medium motor 52 which acts on an extension 53 of the hook 50. It is also possible to mount the hooks 50 on a common shaft which is pivotably mounted on the free ends of the grippers 30 by a pressure medium motor (similar to 52, 53).

Die Anordnung und Formgebung der Haken 50 ist so getroffen, daß sich die freien Enden 54 der Haken 50 aus dem Bereich der an die Anlagestifte 15 angelegten Abstandhalterrahmen 18 herausbewegt haben, wenn die Greifer 30 ihre vollständig nach unten verschwenkte Endstellung ( Abgabestellung Figur 8) einnehmen. In der in Figur 8 gezeigten, unteren Endstellung der Greifer 30 sind die freien Enden 54 der Haken 50 im wesentlichen horizontal ausgerichtet und weisen nach unten. Bis auf das Verschwenken der Haken 50 entspricht die Funktion der erfindungsgemäßen Vorrichtung jener der anhand der Figuren 3 und 4 der in den Figuren 3 bis 7 beschriebenen Ausführungsform. Durch die erfindungsgemäße Ausbildung der Haken 50 an den Greifern 30 können die letzteren ohne Verschwenkung der Haken 50 gegenüber den Greifern 30 vollständig, d. h. so weit in die Abgabestellung eingeschwenkt werden, daß die Haken 50 vom Abstandhalterrahmen 18, genauer dessen obere, horizontale Schenkel frei kommen. Erst dann, d. h. für das Rückschwenken in die Abnahmestellung, werden die Haken 50 ausgeschwenkt, wobei die Haken 50 während des Rückschwenkens in die Abnahmestellung wieder in ihre in Figur 3 gezeigte, für die Abnahme eines Abstandhalterrahmens 18 richtige Lage gegenüber den Greifern 30 verschwenkt werden.The arrangement and shape of the hooks 50 is such that the free ends 54 of the hooks 50 have moved out of the area of the spacer frames 18 applied to the contact pins 15 when the grippers 30 assume their end position pivoted completely downwards (delivery position FIG. 8) . In the lower end position of the grippers 30 shown in FIG. 8, the free ends 54 of the hooks 50 are oriented essentially horizontally and point downwards. Except for the pivoting of the hooks 50, the function of the device according to the invention corresponds to that of the embodiment described in FIGS. 3 and 7 with reference to FIGS. 3 and 4. Due to the inventive design of the hooks 50 on the grippers 30, the latter can be completely pivoted relative to the grippers 30 without pivoting the hooks 50, i. H. are pivoted so far into the delivery position that the hooks 50 come free from the spacer frame 18, more precisely its upper, horizontal leg. Only then, d. H. for swiveling back into the removal position, the hooks 50 are swung out, the hooks 50 being swiveled back into the position shown in FIG. 3, correct for the removal of a spacer frame 18, relative to the grippers 30 during the swiveling back into the removal position.

Da Abstandhalterrahmen 18 mit längeren, horizontalen Rahmenschenkeln mit ihrem unteren, horizontalen Rahmenschenkel durchhängen (oben ist der Rahmenschenkel durch die Haken des Hängeförderers 19 oder durch die Greifer 30 gehalten), kann es vorkommen, daß dieser Rahmenschenkel nicht auf die Auflager der Klemmeinrichtungen 16 gelangt, oder aber der Abstandhalterrahmen 18 muß sehr hoch gehoben werden. Um dies zu vereinfachen, sind insbesondere in der Mitte der erfindungsgemäßen Vorrichtung Hebeglieder in Form von Bügeln 55 vorgesehen. Diese Bügel 55 sind am unteren, horizontalen Schenkel 10 der rahmenartigen Halterung 8 über gewinkelte Träger 56, um eine Achse 57 unter der Einwirkung eines Druckmittelmotors 58 zwischen den in Figur 9 in durchgehenden und in strichlierten Linien dargestellten Lagen verschwenkbar.Since spacer frames 18 with longer, horizontal frame legs sag with their lower, horizontal frame legs (the frame leg is held at the top by the hooks of the overhead conveyor 19 or by the grippers 30), it can happen that this frame leg does not reach the supports of the clamping devices 16, or the spacer frame 18 must be raised very high. To simplify this, lifting members in the form of brackets 55 are provided in the middle of the device according to the invention. These brackets 55 are pivotable on the lower, horizontal leg 10 of the frame-like holder 8 via angled supports 56, about an axis 57 under the action of a pressure medium motor 58 between the positions shown in FIG. 9 in continuous and in dashed lines.

Die flachen Bügel 55 bewegen sich etwa gleichzeitig mit den Greifern 17 oder 30 auf die rahmenartige Halterung 8 der erfindungsgemäßen Vorrichtung zu, so daß auch sonst durchhängende Schenkel von Abstandhalterrahmen sicher auf die Klemmeinrichtungen 16 gehoben werden.The flat brackets 55 move approximately simultaneously with the grippers 17 or 30 towards the frame-like holder 8 of the device according to the invention, so that otherwise sagging legs of the spacer frame are safely lifted onto the clamping devices 16.
