Definitions
- the invention relates to a device for applying viscous compositions, in particular for applying glue to slot and tenon profiles of frame and casement timbers, according to the preamble of patent claim 1.
- Such devices have the advantage that a perfect dosage can be achieved even on the side walls of relatively narrow slots.
- the glue application is not - as with the previously mentioned devices with pendulum swords - dependent on the fact that there is sufficient contact of mechanically moving parts with the diaphragm walls.
- the known devices tend to stick together during a longer standstill, just like the previously mentioned spray nozzles, so that whenever, e.g. for the purpose of converting the distribution elements to other tenon profiles, a standstill is required, the entire distribution elements must be cleaned carefully.
- the invention is based on the object of designing a device of this type so that sticking is largely avoided.
- the invention offers the previously unattainable advantage that the nozzle pipes causing the glue application can be sealed exactly and tightly after use, while at the same time excess glue, possibly still adhering to the nozzle pipes, is wiped clean.
- a device according to the invention therefore also has the advantage that it can be switched off if necessary without the risk of disadvantages due to the drying properties of the glue.
- the features of claim 2 allow the length of the nozzle tubes to be adapted in a simple manner to the depth and to the transverse dimensions of the slot-pin profiles.
- the features of claim 3 supplement this embodiment insofar as the corresponding adjustment of the wiping sleeves is possible.
- the features of claim 4 make it possible to form prepared interchangeable structural units which are suitable for specific, mostly standardized slot-and-tenon connections and can therefore be exchanged in the gluing device as required.
- a gluing device which consists of a machine frame (1) with a support guide consisting of rollers (2) for a workpiece (3), which in the exemplary embodiment has a slot and pin profile (4) frame or wing wood provided on both ends, which, after a corresponding application of glue, is glued with these slot and tenon profiles (4), which are shown in FIG. 10 using an example, in a frame press, not shown should.
- the workpiece (3) has moved against a stop (5) of the gluing device and is held in this position in a manner not shown.
- the stop (5) which can also be designed as a probe, is part of a gluing head (6) mounted in the machine frame (1), which, with the help of a working cylinder (7), is pneumatic or hydraulic in height, for example in the end position shown in Fig. 8 (6 ') or can still be moved.
- An adjustment rail (8) is fixedly arranged in the movable gluing head (6), on which clamping blocks (10) can be adjusted and locked in the longitudinal direction (arrows 9).
- Nozzle tubes (11) are held in these clamping blocks (10), each of which can be adjusted in the direction of their axis in these clamping blocks in a manner not shown in detail and can be locked in the set axial position.
- Fig. 2 shows that the length (1) of the four nozzle tubes (11) in the embodiment is the same size, but that the distance (a) of the free end of one of the nozzle tubes (11) from the associated clamping block (10) compared to the other Nozzle pipes is different. This distance (a) of the front end of each nozzle tube from the adjustment rail (8) can therefore be adjusted and adapted to the depth of the slots between the pins of the slot-pin profile (4).
- Each of the nozzle tubes (11) is connected in a manner not shown via a pressure hose line attached to the end (11a) to a glue supply, which is carried out in the usual way via a glue pump from a storage container.
- a sliding bar (12) is provided, which runs laterally in horizontal guides (not shown) and with the help of a pneumatic or hydraulic working cylinder (13) in the direction of the arrows ( 14) can be moved.
- Clamping blocks (15) in the same number as the clamping blocks (10) are also provided on this sliding bar (12). These clamping blocks (15) can in turn be adjusted on the sliding bar (12) in the direction of the arrows (9) in such a way that the clamping blocks (15) lie opposite the clamping blocks (10).
- a stripping sleeve (16) is provided, which is provided at its free end facing the associated nozzle tube (11) with a blind bore (17), the depth of which corresponds to the length of the associated one corresponds to the free end of the nozzle tube (11) and the inside diameter corresponds to the diameter of the cylindrical nozzle tubes (11) used in the exemplary embodiment.
- no cylindrical nozzle tubes need to be provided.
- Flat tubes or other cross-sectional shapes are also possible. Cylindrical nozzle tubes are, however, simpler and also allow the stripping sleeves (16) to be made correspondingly simple.
- each of the nozzle tubes (11) is provided on the circumference along a surface line with openings (18) designed as bores, which are arranged at a predetermined distance (b) from one another in the longitudinal direction of the nozzle tubes (11) .
- Fig. 4 shows that these holes (18) can be provided not only on one side of the nozzle tubes (11), but also on diametrically opposite sides, in order, as will be explained later, a glue application also on two opposite walls within the Apply groove of a slot-tenon profile. Where this is not necessary and a glue application on one side is sufficient, only one is sufficient Side holes (18). This will be explained with reference to FIG. 9, where the possibility shown in FIG. 5 is also discussed, also at the front end (11b) of each nozzle tube (11) or a part of the nozzle tubes (11) an end-side bore ( 19) to be attached.
- the gluing head (6) is then in a position which is even higher than the position (6 ') shown in FIG. 8, in which the nozzle tubes (11) are located within the slot-pin profile (4) .
- the control of the glue supply through the bores (18) takes place in such a way that glue beads (21) on all side walls (22, 23, 24 and 25) of the slotted-spigot as the arrow tubes (11) pass by (20) Profiles (4) and, if necessary, also on the chest surfaces (26, 27 and 28) or, as Fig. 9 shows, only on the outer chest surfaces (28a and 26a).
- the glue supply therefore switches on when the nozzle pipes (11) have reached the corresponding lower point on the slot-pin profile (4) and switches off again when the area of the upper edge of this slot-pin profile is reached (3) is then removed and can, if necessary, also be carried out fully automatically, into a frame press, where it is pressed together with other frame or casement timbers to the desired frame.
- the glueing head (6) then returns to its initial position according to FIG. 1.
- the stripping sleeves (16) are pushed with the help of the working cylinder (13) over the nozzle tubes (11) when the gluing process or a series of gluing processes has ended.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Auftragen von viskosen Massen, insbesondere zum Auftragen von Leim auf Schlitz- und Zapfenprofile von Rahmen- und Flügelhölzern nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for applying viscous compositions, in particular for applying glue to slot and tenon profiles of frame and casement timbers, according to the preamble of patent claim 1.
Zum Auftragen von Leim auf Rahmen- oder Flügelhölzer ist es bekannt (HESS-Leimangabe-Automat, Prospekt der Firma Reinhold Hess GmbH & Co. KG, Balingen), den Leim mit Hilfe von Tauchschwertern aus einem Leimbad zu entnehmen, von diesen Pendelschwertern den Leim mit Ausnahme von zurückbleibenden Kleberaupen mit Hilfe von Abstreifern zu entfernen und die Pendelschwerter in die Schlitze zwischen den Zapfenprofilen einzuführen und sie durch Pendelbewegungen an die entsprechenden Flächen zu bringen. Solche Auftragvorrichtungen arbeiten mit einem offenen Leimbad. Ein Stillstand der Einrichtung führt zu einem unerwünschten Austrocken des Leimes.To apply glue to frame or wing wood, it is known (HESS glue dispenser, brochure from Reinhold Hess GmbH & Co. KG, Balingen) to remove the glue from a glue bath with the help of immersion swords, the glue from these pendulum swords with the exception of remaining adhesive beads with the help of scrapers and insert the pendulum swords into the slots between the tenon profiles and bring them to the corresponding surfaces by pendulum movements. Such application devices work with an open glue bath. A standstill of the device leads to an undesirable drying out of the glue.
Bekannt sind deshalb auch schon Vorrichtungen der eingangs genannten Art (Prospekt HESS-LEIMLUX der Firma Reinhold Hess GmbH & Co. KG, Balingen), bei denen der Leim nicht mehr aus einem offenen Bad entnommen, sondern jeweils durch Sprühdüsen aus einem Drucksystem kommt, die mit Hilfe von Armen so gut als möglich an die jeweils mit Leim zu versehenden Flächen gebracht werden. Auch hier ergeben sich bei längerem Stillstand aber Schwierigkeiten, weil die Sprühdüsen verkleben können. Vor allen Dingen aber lassen sich die Sprühdüsen wegen ihres Raumbedarfes im Gegensatz zu den Pendelschwertern nicht in schmale Zwischenräume führen, die zwischen Zapfenprofilen vorhanden sind. Der Leim muß hier daher unter Druck in die Schlitze eingesprüht werden. Er kann dabei nicht immer in der gewünschten Weise plaziert werden.Devices of the type mentioned at the outset (brochure HESS-LEIMLUX from Reinhold Hess GmbH & Co. KG, Balingen) are therefore already known, in which the glue is no longer removed from an open bath, but rather comes from a pressure system through spray nozzles brought with the help of arms as best as possible to the areas to be glued become. Here, too, there are difficulties with long periods of inactivity because the spray nozzles can stick together. Above all, however, the spray nozzles, because of their space requirement, in contrast to the pendulum swords, cannot be led into narrow spaces that are present between peg profiles. The glue must therefore be sprayed into the slots under pressure. It cannot always be placed in the desired manner.
Aus der DE-A-16 52 439 ist es bekannt, Verteilorgane in der Form von auswechselbaren Blöcken vorzusehen, die mit Hauptzuführbohrungen und mit Sekundärbohrungen versehen sind, die entweder an den Stirnseiten oder an den Seitenflächen der Blöcke münden und dazu dienen, Klebstoff, der aus einem gemeinsamen Halter geliefert wird, an die zu beleimenden Flächen zu verteilen. Dabei werden, um jeweils eine Anpassung an verschiedene Zapfenprofile zu erreichen, mehrere der Blöcke nebeneinander in einem Halter aufgenommen, der gleichzeitig auch die Klebstoffzuführung bildet.From DE-A-16 52 439 it is known to provide distributing members in the form of interchangeable blocks which are provided with main feed bores and with secondary bores which open either on the end faces or on the side faces of the blocks and serve to glue the is supplied from a common holder to distribute to the surfaces to be glued. In order to adapt to different tenon profiles, several of the blocks are accommodated next to one another in a holder, which at the same time also forms the adhesive feed.
Solche Vorrichtungen weisen den Vorteil auf, daß sich eine einwandfreie Dosierung auch an den Seitenwänden von verhältnismäßig engen Schlitzen erreichen läßt. Dabei ist der Leimauftrag nicht - wie bei den vorher genannten Einrichtungen mit Pendelschwertern - davon abhängig, daß eine ausreichende Berührung mechanisch bewegter Teile mit den Schlitzwänden erfolgt. Die bekannten Vorrichtungen neigen aber bei einem längeren Stillstand, ebenso wie die vorher erwähnten Sprühdüsen, zum Verkleben, so daß immer dann, wenn z.B. zum Zweck der Umstellung der Verteilorgane auf andere Zapfenprofile, ein Stillstand erforderlich wird, die gesamten Verteilorgane sorgfältig gereinigt werden müssen.Such devices have the advantage that a perfect dosage can be achieved even on the side walls of relatively narrow slots. The glue application is not - as with the previously mentioned devices with pendulum swords - dependent on the fact that there is sufficient contact of mechanically moving parts with the diaphragm walls. The known devices, however, tend to stick together during a longer standstill, just like the previously mentioned spray nozzles, so that whenever, e.g. for the purpose of converting the distribution elements to other tenon profiles, a standstill is required, the entire distribution elements must be cleaned carefully.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Vorrichtung dieser Art so auszubilden, daß ein Verkleben weitgehend vermieden wird.The invention is based on the object of designing a device of this type so that sticking is largely avoided.
Zur Lösung dieser Aufgabe werden bei einer Vorrichtung der eingangs genannten Art die kennzeichnenden Merkmale des Anspruches 1 vorgesehen.To achieve this object, the characterizing features of claim 1 are provided in a device of the type mentioned.
Die Erfindung bietet den bisher nicht zu verwirklichenden Vorteil, daß die den Leimauftrag bewirkenden Düsenrohre nach Gebrauch exakt und dicht verschlossen werden können, wobei gleichzeitig überschüssiger, eventuell noch an den Düsenrohren außen anhaftender Leim sauber abgestreift wird. Eine Vorrichtung nach der Erfindung weist daher auch den Vorteil auf, daß sie bei Bedarf abgestellt werden kann, ohne daß Nachteile durch die Trocknungseigenschaften des Leimes zu befürchten sind.The invention offers the previously unattainable advantage that the nozzle pipes causing the glue application can be sealed exactly and tightly after use, while at the same time excess glue, possibly still adhering to the nozzle pipes, is wiped clean. A device according to the invention therefore also has the advantage that it can be switched off if necessary without the risk of disadvantages due to the drying properties of the glue.
Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen. Die Merkmale des Anspruches 2 erlauben es in einfacher Weise, die Länge der Düsenrohre an die Tiefe und an die Querabmessungen der Schlitz-Zapfen-Profile anzupassen. Die Merkmale des Anspruches 3 ergänzen diese Ausgestaltung insofern, als auch die entsprechende Anpassung der Abstreifhülsen möglich ist. Die Merkmale des Anspruches 4 schließlich erlauben es, vorbereitete austauschbare Baueinheiten zu bilden, die für bestimmte, meist genormte Schlitz-Zapfen-Verbindungen geeignet sind und sich daher je nach Bedarf in der Beleimvorrichtung austauschen lassen.Further advantageous embodiments result from the subclaims.

In den Fig. 1 bis 5 ist eine Beleimvorrichtung gezeigt, die aus einem Maschinengestell (1) mit einer aus Rollen (2) bestehenden Auflageführung für ein Werkstück (3) besteht, das beim Ausführungsbeispiel ein mit einem Schlitz- und Zapfenprofil (4) an beiden Stirnenden versehenes Rahmen- oder Flügelholz ist, das nach einem entsprechenden Leimauftrag mit diesen Schlitz- und Zapfenprofilen (4), die anhand eines Beispieles in Fig. 10 gezeigt sind, in einer nicht gezeigten Rahmenpresse verleimt werden soll. Das Werkstück (3) ist zu diesem Zweck gegen einen Anschlag (5) der Beleimvorrichtung gefahren und wird in nicht näher dargestellter Weise in dieser Lage gehalten.1 to 5, a gluing device is shown which consists of a machine frame (1) with a support guide consisting of rollers (2) for a workpiece (3), which in the exemplary embodiment has a slot and pin profile (4) frame or wing wood provided on both ends, which, after a corresponding application of glue, is glued with these slot and tenon profiles (4), which are shown in FIG. 10 using an example, in a frame press, not shown should. For this purpose, the workpiece (3) has moved against a stop (5) of the gluing device and is held in this position in a manner not shown.
Der Anschlag (5), der zusätzlich auch als ein Tastkopf ausgebildet sein kann, ist Teil eines in dem Maschinengestell (1) gelagerten Beleimkopfes (6), der mit Hilfe eines Arbeitszylinders (7) pneumatischer oder hydraulischer Art in der Höhe bis in die beispielsweise in der Fig. 8 gezeigte Endstellung (6') oder noch verfahren werden kann. In dem verfahrbaren Beleimkopf (6) ist eine Verstellschiene (8) fest angeordnet, an der in deren Längsrichtung (Pfeile 9) Klemmklötze (10) einstellbar und arretierbar befestigt sind. In diesen Klemmklötzen (10) sind Düsenrohre (11) gehalten, die jeweils in nicht näher gezeigter Weise in diesen Klemmklötzen in Richtung ihrer Achse einstellbar und in der eingestellten Axiallage arretierbar sind.The stop (5), which can also be designed as a probe, is part of a gluing head (6) mounted in the machine frame (1), which, with the help of a working cylinder (7), is pneumatic or hydraulic in height, for example in the end position shown in Fig. 8 (6 ') or can still be moved. An adjustment rail (8) is fixedly arranged in the movable gluing head (6), on which clamping blocks (10) can be adjusted and locked in the longitudinal direction (arrows 9). Nozzle tubes (11) are held in these clamping blocks (10), each of which can be adjusted in the direction of their axis in these clamping blocks in a manner not shown in detail and can be locked in the set axial position.
Die Fig. 2 zeigt, daß die Länge (1) der vier Düsenrohre (11) beim Ausführungsbeispiel zwar gleich groß ist, daß aber der Abstand (a) des freien Stirnendes eines der Düsenrohre (11) vom zugeordneten Klemmklotz (10) gegenüber den anderen Düsenrohren unterschiedlich ist. Dieser Abstand (a) des Stirnendes jedes Düsenrohres von der Verstellschiene (8) läßt sich daher einstellen und jeweils an die Tiefe der Schlitze zwischen den Zapfen des Schlitz-Zapfen-Profiles (4) anpassen. Jedes der Düsenrohre (11) ist in nicht näher dargestellter Weise über eine am Ende (11a) angebrachte Druckschlauchleitung an eine Leimzufuhr angeschlossen, die in üblicher Weise über eine Leimpumpe von einem Vorratsbehälter aus erfolgt.Fig. 2 shows that the length (1) of the four nozzle tubes (11) in the embodiment is the same size, but that the distance (a) of the free end of one of the nozzle tubes (11) from the associated clamping block (10) compared to the other Nozzle pipes is different. This distance (a) of the front end of each nozzle tube from the adjustment rail (8) can therefore be adjusted and adapted to the depth of the slots between the pins of the slot-pin profile (4). Each of the nozzle tubes (11) is connected in a manner not shown via a pressure hose line attached to the end (11a) to a glue supply, which is carried out in the usual way via a glue pump from a storage container.
Dabei soll zunächst davon ausgegangen werden, daß alle Düsenrohre (11) an einer gemeinsamen Druckquelle anliegen, wobei die Leimzufuhr zu allen Düsenrohren (11) über ein gemeinsames Steuerventil erfolgt. Natürlich wäre es auch möglich, jedem einzelnen Düsenrohr oder einer Gruppe von Düsenrohren ein eigenes Steuerventil zuzuordnen, wenn dies erforderlich sein sollte.It should initially be assumed that all nozzle pipes (11) are in contact with a common pressure source, the glue supply to all nozzle pipes (11) being carried out via a common control valve. Of course, it would also be possible to assign a separate control valve to each individual nozzle tube or a group of nozzle tubes if this should be necessary.
In dem Maschinengestell (1) ist gegenüber der im Beleimkopf (6) angeordneten Verstellschiene (8) eine Verschiebeleiste (12) vorgesehen, die seitlich in nicht gezeigten horizontalen Führungen läuft und mit Hilfe eines pneumatischen oder hydraulischen Arbeitszylinders (13) in Richtung der Pfeile (14) verschoben werden kann. Auf dieser Verschiebeleiste (12) sind ebenfalls Klemmklötze (15) in der gleichen Anzahl wie die Klemmklötze (10) vorgesehen. Diese Klemmklötze (15) lassen sich auf der Verschiebeleiste (12) wiederum in Richtung der Pfeile (9) verstellen, und zwar so, daß die Klemmklötze (15) den Klemmklötzen (10) gegenüberliegen.In the machine frame (1), opposite the adjustment rail (8) arranged in the glueing head (6), a sliding bar (12) is provided, which runs laterally in horizontal guides (not shown) and with the help of a pneumatic or hydraulic working cylinder (13) in the direction of the arrows ( 14) can be moved. Clamping blocks (15) in the same number as the clamping blocks (10) are also provided on this sliding bar (12). These clamping blocks (15) can in turn be adjusted on the sliding bar (12) in the direction of the arrows (9) in such a way that the clamping blocks (15) lie opposite the clamping blocks (10).
In jedem der Klemmklötze (15) ist wiederum in Richtung ihrer Längsachse verschiebbar eine Abstreifhülse (16) gehalten, die an ihrem freien, dem zugeordneten Düsenrohr (11) zugewandten Ende mit jeweils einer Sackbohrung (17) versehen ist, deren Tiefe der Länge des zugeordneten freien Endes des Düsenrohres (11) entspricht und deren lichte Weite dem Durchmesser der beim Ausführungsbeispiel verwendeten zylindrischen Düsenrohre (11) entspricht. Natürlich brauchen keine zylindrischen Düsenrohre vorgesehen zu werden. Auch Flachrohre oder andere Querschnittsformen sind möglich. Zylindrische Düsenrohre sind allerdings einfacher und erlauben es auch, die Abstreifhülsen (16) entsprechend einfach zu gestalten.In each of the clamping blocks (15) is in turn slidable in the direction of its longitudinal axis, a stripping sleeve (16) is provided, which is provided at its free end facing the associated nozzle tube (11) with a blind bore (17), the depth of which corresponds to the length of the associated one corresponds to the free end of the nozzle tube (11) and the inside diameter corresponds to the diameter of the cylindrical nozzle tubes (11) used in the exemplary embodiment. Of course, no cylindrical nozzle tubes need to be provided. Flat tubes or other cross-sectional shapes are also possible. Cylindrical nozzle tubes are, however, simpler and also allow the stripping sleeves (16) to be made correspondingly simple.
Die Fig.3 bis 5 zeigen, daß jedes der Düsenrohre (11) am Umfang längs einer Mantellinie mit als Bohrungen ausgebildeten Öffnungen (18) versehen ist, die in einem vorbestimmten Abstand (b) zueinander in der Längsrichtung der Düsenrohre (11) angebracht sind. Fig. 4 zeigt, daß diese Bohrungen (18) nicht nur auf einer Seite der Düsenrohre (11), sondern auch auf diametral gegenüberliegenden Seiten vorgesehen sein können, um, wie später noch erläutert werden wird, eine Leimaufgabe auch an zwei gegenüberliegende Wandungen innerhalb der Nut eines Schlitz-Zapfen-Profiles aufzubringen. Wo das nicht notwendig ist und eine Leimaufgabe nach einer Seite genügt, reichen auch nur auf einer Seite angeordnete Bohrungen (18). Dies wird anhand von Fig. 9 noch erläutert werden, wo auch auf die Möglichkeit eingegangen wird, die in Fig. 5 gezeigt ist, auch am Stirnende (11b) jedes Düsenrohres (11) oder eines Teiles der Düsenrohre (11) eine stirnseitige Bohrung (19) anzubringen.3 to 5 show that each of the nozzle tubes (11) is provided on the circumference along a surface line with openings (18) designed as bores, which are arranged at a predetermined distance (b) from one another in the longitudinal direction of the nozzle tubes (11) . Fig. 4 shows that these holes (18) can be provided not only on one side of the nozzle tubes (11), but also on diametrically opposite sides, in order, as will be explained later, a glue application also on two opposite walls within the Apply groove of a slot-tenon profile. Where this is not necessary and a glue application on one side is sufficient, only one is sufficient Side holes (18). This will be explained with reference to FIG. 9, where the possibility shown in FIG. 5 is also discussed, also at the front end (11b) of each nozzle tube (11) or a part of the nozzle tubes (11) an end-side bore ( 19) to be attached.
Die Arbeitsweise der neuen Beleimvorrichtung wird im folgenden anhand der Fig. 6 bis 8 und der damit erzielbare Beleimvorgang anhand der Fig. 9 und 10 erläutert werden.The operation of the new gluing device will be explained in the following with reference to FIGS. 6 to 8 and the gluing process which can be achieved therewith with reference to FIGS. 9 and 10.
Aus der Fig.6 und 7 ist zunächst zu erkennen, daß sich in einem ersten Arbeitsschritt, nachdem das Werkstück (3) positioniert ist, auf dessen Schlitz-Zapten-Verbindung die Düsenrohre (11) und die dazugehörigen Abstreifhülsen (6) in der beschriebenen Weise eingestellt sind, die Abstreifhülsen (16) durch Beaufschlagung des Arbeitszylinders (13) nach links bewegen, und zwar so weit, daß die Düsenrohre (11) freigegeben werden. In einem nachfolgenden Arbeitsschritt wird der Arbeitszylinder (7) aktiviert und schiebt den Beleimkopf (6) aus der Position der Fig. 6 nach oben, und zwar so weit, daß die Düsenrohre (11) gemäß den Fig. 9 und 10 in Richtung des Pfeiles (20) an der Schlitz-Zapfen-Verbindung (4) des Werkstückes (3) vorbei bis in eine Endlage (11') geführt werden. Der Beleimkopf (6) befindet sich dann in einer Stellung, die noch höher ist, als die in der Fig. 8 gezeigte Stellung (6'), in der sich die Düsenrohre (11) innerhalb des Schlitz-Zapfen-Profiles (4) befinden. Die Steuerung der Leimzufuhr durch die Bohrungen (18) erfolgt dabei so, daß beim Vorbeifahren der Düsenrohre (11) im Sinne des Pfeiles (20) Leimraupen (21) an allen Seitenwänden (22, 23, 24 und 25) des Schlitz-Zapfen-Profiles (4) und, falls erforderlich, auch an den Brustflächen (26, 27 und 28) oder, wie Fig. 9 zeigt, nur an den äußeren Brustflächen (28a und 26a) gebildet werden. Die Leimzufuhr schaltet daher ein, wenn die Düsenrohre (11) die entsprechende untere Stelle am Schlitz-Zapfen-Profil (4) erreicht haben und schaltet wieder ab, wenn der Bereich der Oberkante dieses Schlitz-Zapfen-Profiles erreicht ist.Das Werkstück (3) wird dann entnommen und kann, gegebenenfalls auch voll automatisch, in eine Rahmenpresse weitergeführt werden, wo es mit anderen Rahmen- oder Flügelhölzern zu dem gewünschten Rahmen verpreßt wird. Der Beleimkopf (6) geht anschließend wieder in seine Ausgangsstellung nach Fig. 1 zurück. Die Abstreifhülsen (16) werden mit Hilfe des Arbeitszylinders (13) über die Düsenrohre (11) geschoben, wenn der Beleimvorgang oder eine Serie von Leimvorgängen beendet ist.6 and 7 it can first be seen that in a first step after the workpiece (3) has been positioned, the nozzle tubes (11) and the associated wiping sleeves (6) are described on the slot-pin connection Are set, move the scraper sleeves (16) by acting on the working cylinder (13) to the left, to the extent that the nozzle tubes (11) are released. In a subsequent step, the working cylinder (7) is activated and pushes the gluing head (6) upwards from the position of FIG. 6, to the extent that the nozzle tubes (11) according to FIGS. 9 and 10 in the direction of the arrow (20) past the slot-pin connection (4) of the workpiece (3) to an end position (11 '). The gluing head (6) is then in a position which is even higher than the position (6 ') shown in FIG. 8, in which the nozzle tubes (11) are located within the slot-pin profile (4) . The control of the glue supply through the bores (18) takes place in such a way that glue beads (21) on all side walls (22, 23, 24 and 25) of the slotted-spigot as the arrow tubes (11) pass by (20) Profiles (4) and, if necessary, also on the chest surfaces (26, 27 and 28) or, as Fig. 9 shows, only on the outer chest surfaces (28a and 26a). The glue supply therefore switches on when the nozzle pipes (11) have reached the corresponding lower point on the slot-pin profile (4) and switches off again when the area of the upper edge of this slot-pin profile is reached (3) is then removed and can, if necessary, also be carried out fully automatically, into a frame press, where it is pressed together with other frame or casement timbers to the desired frame. The glueing head (6) then returns to its initial position according to FIG. 1. The stripping sleeves (16) are pushed with the help of the working cylinder (13) over the nozzle tubes (11) when the gluing process or a series of gluing processes has ended.
Es ist möglich, wie auch anhand der Fig. 2 und 7 einerseits und der Fig.9 andererseits erkennbar ist, den gegenseitigen Abstand der Düsenrohre (11) und, wie vorher schon erwähnt, ihre axiale Länge (a) entsprechend dem zu beleimenden Schlitz-Zapfen-Profil einzustellen. Es hat sich aber als besonders einfach erwiesen, für die auf dem Markt befindlichen, in der Regel genormten Schlitz-Zapfen-Profile,einen vorbereiteten Satz von Düsenrohren (11) mit Verstellschiene (8) und einen korrespondierenden Satz Abstreifhülsen (16) mit Verschiebeleiste (12) vorzusehen, die jeweils als Ganzes in dem Beleimkopf bzw.im Maschinengestell (1) montiert werden. Die Umstellung auf andere zu beleimende Profile ist auf diese Weise äußerst einfach.It is possible, as can also be seen from FIGS. 2 and 7 on the one hand and FIG. 9 on the other hand, the mutual spacing of the nozzle pipes (11) and, as already mentioned above, their axial length (a) in accordance with the slot to be glued. Adjust pin profile. However, it has proven to be particularly simple for the generally standardized slotted-spigot profiles on the market, a prepared set of nozzle pipes (11) with an adjusting rail (8) and a corresponding set of stripping sleeves (16) with a sliding bar ( 12) to be provided, which are each assembled as a whole in the gluing head or in the machine frame (1). Switching to other profiles to be glued is extremely easy in this way.
