Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Schmelzklebevorrichtung nach der Gattung des Hauptanspruchs. Bekannte Vorrichtungen dieser Art erwärmen den in Patronenform einschiebbaren Schmelzkleber auf Schmelztemperatur und . gestatten das Ausbringen des geschmolzenen Klebers auf das Werkstück durch eine warme Düse. Die Qualität der Klebung ist dabei stark abhängig von der Wärmeleitfähigkeit des Werkstoffs aus dem das Werkstück besteht. Bei stark wärmeleitenden Stoffen wie Metallen oder dgl. wird der durch die Düse ausströmenden Klebemasse so schnell die Wärme entzogen, daß eine einwandfreie Schmelzklebung nicht zustande kommt.The invention is based on a hot melt adhesive device according to the preamble of the main claim. Known devices of this type heat the insertable hot melt adhesive to the melting temperature and. allow the molten adhesive to be applied to the workpiece through a warm nozzle. The quality of the bond is strongly dependent on the thermal conductivity of the material from which the workpiece is made. In the case of highly heat-conducting substances such as metals or the like, the heat which is emitted through the nozzle is withdrawn from the heat so quickly that flawless hotmelt bonding does not occur.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Schmelzklebevorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß auch stark wärmeleitende Stoffe mit der gewünschten Qualität der Klebeverbindung geklebt werden könnten. Durch das Vorheizen des zu klebenden Werkstückes mittels eines mit der Schmelzklebevorrichtung verbundenen Wärmestrahlers wird auch bei stark wärmeleitenden Stoffen eine einwandfreie Schmelzklebung sichergestellt.The hot melt adhesive device according to the invention with the characterizing features of the main claim has the advantage that even highly thermally conductive materials could be glued with the desired quality of the adhesive bond. By preheating the workpiece to be glued by means of a heat radiator connected to the hot-melt gluing device, perfect hot-melt gluing is ensured even with highly heat-conducting materials.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Schmelzklebevorrichtung möglich. Besonders vorteilhaft ist die Bündelung der Wärmestrahlung, dies besonders zusammen mit der Möglichkeit das Strahlungsbündel zu schwenken und/oder die _Wärmestrahlung im Bedarfsfalle getrennt ein- oder auszuschalten. Eine weitestgehende Anpassung der Arbeitsweise an verschiedene Werkstoffe und Formen des Werkstücks ist damit ermöglicht.The measures listed in the subclaims enable advantageous developments and improvements of the hot-melt adhesive device specified in the main claim. It is particularly advantageous to bundle the heat radiation, particularly together with the possibility of pivoting the radiation beam and / or switching the heat radiation on or off separately if necessary. This enables the work to be largely adapted to different materials and shapes of the workpiece.

Zeichnungdrawing

Zwei Ausführungsbeisiele des Erfindungsgegenstandes sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 eine Seitenansicht einer pistolenförmig gestalteten Schmelzklebevorrichtung nach einem ersten Ausführungsbeispiel, Figur 2 eine Seitenansicht zu Figur 1, Figur 3 ein zweites Ausführungsbeispiel einer erfindungsgemäßen Schmelzklebevorrichtung mit einem angesetzten Wärmestrahler und Figur 4 eine Seitenansicht zu Figur 3.Two exemplary embodiments of the subject matter of the invention are shown in the drawing and explained in more detail in the description below. FIG. 1 shows a side view of a pistol-shaped hot melt adhesive device according to a first exemplary embodiment, FIG. 2 shows a side view of FIG. 1, FIG. 3 shows a second exemplary embodiment of a hot melt adhesive device according to the invention with a heat radiator attached, and FIG. 4 shows a side view view to Figure 3.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Im ersten Ausführungsbeispiel nach den Figuren 1 und 2 ist ein Gehäuse aus zwei Halbschalen 1 und 2 gebildet. Diese Halbschalen umfassen eine Patronenführung 3 und eine Patronenheizung die im einzelnen nicht näher dargestellt sind. Außerdem nimmt dieses Gehäuse 1/2 eine Düse 4, einen Hauptschalter mit einer Schalthandhabe 5 einen Wärmestrahler 6 und einen Ein- und Ausschalter 7 für diesen Wärmestrahler 6 auf. Der Wärmestrahler 6 besteht im einzelnen aus einem fest eingebauten Reflektor 8, einer auswechselbar eingesetzten Strahlungsquelle 9 und einer den Reflektor 8 nach außen abschließenden Sammellinse 10. Die mit einem pistolenförmig gestalteten Gehäuse versehene Schmelzklebevorrichtung kann über ein Kabel 11 mit einem normalen Spannungsnetz verbunden werden. Der Schmelzkleber ist in die Form von Patronen 12 gebracht, die von hinten her in die Patronenführung 3 eingeschoben werden können.In the first exemplary embodiment according to FIGS. 1 and 2, a housing is formed from two half-shells 1 and 2. These half-shells include a cartridge guide 3 and a cartridge heater which are not shown in detail. In addition, this housing 1/2 accommodates a nozzle 4, a main switch with a switching handle 5, a heat radiator 6 and an on / off switch 7 for this heat radiator 6. The heat radiator 6 consists in particular of a permanently installed reflector 8, an interchangeably used radiation source 9 and a collecting lens 10 which closes the reflector 8 to the outside. The hot melt adhesive is brought into the form of cartridges 12, which can be inserted into the cartridge guide 3 from behind.

Der Wärmestrahler 6 strahlt ein Bündel von Wärmestrahlung ab, das fest ausgerichtet ist auf eine Stelle des Werkstückes, die etwas oberhalb der Austrittsöffnung der Düse 4 liegt. Damit ist ein aus gut wärmeleitendem Material gefertigtes Werkstück leicht auf eine Temperatur vorzuheizen, die die Schmelzverklebung mit dem aus der Düse austretenden Schmelzkleber begünstigt. Soll ein schlecht wärmeleitendes Material geklebt werden, so kann der Wärmestrahler 6 abgeschaltet werden. Dieses Material entzieht dem geschmolzen aus der Düse 4 fließenden Kleber so wenig Wärme, daß die Verschmelzung auch ohne.die Leistung des Wärmestrahlers optimal erfolgt.The heat radiator 6 emits a bundle of heat radiation, which is fixedly aligned to a point on the workpiece which is slightly above the outlet opening of the nozzle 4. This makes it easy to preheat a workpiece made of a good heat-conducting material to a temperature that the fusion bond with the hot-melt adhesive emerging from the nozzle favored. If a poorly heat-conducting material is to be glued, the heat radiator 6 can be switched off. This material extracts so little heat from the melted adhesive flowing from the nozzle 4 that the fusion takes place optimally even without the performance of the heat radiator.

Im zweiten Ausführungsbeispiel nach den Figuren 3 und wird das Gehäuse der Schmelzklebevorrichtung aus zwei Halbschalen 13 und 14 gebildet. Auch dieses Gehäuse nimmt die Patronenführung 3, die Düse 4, die Schalthandhabe 5 mit dem zugehörigen Hauptschalter, den Schalter 7 und das Ende des Zuleitungskabels 11 auf. Im Gegensatz zu dem Gehäuse nach dem ersten Ausführungsbeispiel mit den Halbschalen 1 und 2 nimmt das Gehäuse mit den Halbschalen 13 und 14 keinen Wärmestrahler auf. Dieses Gehäuse hat vielmehr eine steckdosenähnliche Öffnung 15 mit Steckerbuchsen 16. In diese Öffnung 15 paßt ein Fuß 17 und in die Steckerbuchsen je ein Stecker 18 eines Zusatzgehäuses 19. Das Zusatzgehäuse 19 hat die Form eines nach einer Seite offenen Kastens und enthält einen Reflektor 20. Dieser Reflektor 20 lagert schwenkbar um eine Achse 21 im Zusatzgehäuse 19. Zwei Fassungen 22 der Strahlungsquelle 9 werden gehalten von zwei Halterungen 23 und 24. Während die Halterung 23 drehfest mit dem Reflektor 20 und einem Rändelknopf 25 verbunden ist, nimmt die Halterung 24 eine Rändelschraube 26 so auf, daß die vom Gewindeteil der Rändelschraube 26 durchgriffenen Seitenwände des Zusatzgehäuses 19 und des Reflektors 20 zwischen der Halterung 24 und dem Bund der Rändelschraube 26 festgeklemmt werden können. Da die Halterung 23 und der Rändelknopf 25 nicht nur miteinander sondern auch mit der zwischen ihnen liegenden Seitenwand des Reflektors 20 drehfest verbunden sind, kann mit dem Rändelknopf 25, nach dem Lösen der Rändelschraube 26, der Reflektor 20 im Zusatzgehäuse 19 verschwenkt werden. Mit ihm schwenkt auch eine den Reflektor nach vorn verschließende Sammellinse 27. Die Brennweite der Sammellinse 27 ist vorzugsweise so gewählt, daß sie die Strahlungsquelle 9 in der Nähe der Austrittsöffnung der Düse 4 abbildet.In the second exemplary embodiment according to FIGS. 3 and 4, the housing of the hot-melt adhesive device is formed from two half-shells 13 and 14. This housing also accommodates the cartridge guide 3, the nozzle 4, the switching handle 5 with the associated main switch, the switch 7 and the end of the supply cable 11. In contrast to the housing according to the first exemplary embodiment with the half-shells 1 and 2, the housing with the half-shells 13 and 14 does not accommodate any heat radiators. Rather, this housing has a socket-like opening 15 with sockets 16. A foot 17 fits into this opening 15 and a plug 18 of an additional housing 19 fits into the sockets. The additional housing 19 has the shape of a box open on one side and contains a reflector 20. This reflector 20 is pivotally mounted about an axis 21 in the additional housing 19. Two holders 22 of the radiation source 9 are held by two holders 23 and 24. While the holder 23 is non-rotatably connected to the reflector 20 and a knurled knob 25, the holder 24 takes a knurled screw 26 so that the threaded part of the knurled screw 26 through the side walls of the additional housing 19 and the reflector 20 can be clamped between the bracket 24 and the collar of the knurled screw 26. Since the bracket 23 and the knurled knob 25 not only are rotatably connected to each other but also to the side wall of the reflector 20 between them, the reflector 20 in the additional housing 19 can be pivoted with the knurled knob 25 after loosening the knurled screw 26. It also pivots a collecting lens 27 closing the reflector to the front. The focal length of the collecting lens 27 is preferably selected so that it images the radiation source 9 in the vicinity of the outlet opening of the nozzle 4.

Wird zum Arbeiten mit der Schmelzklebevorrichtung nach dem zweiten Ausführungsbeispiel das Zusatzgehäuse 19 mit seinem Fuß 17 in die Öffnung 15 eingesetzt und der Schalter 7 angeschaltet, so kann man nach dem Lösen der Rändelschraube 26 mittels des Rändelknopfes 25 den Reflektor 20 so schwenken, daß eine optimale Vorheizung des zu klebenden Werkstücks erfolgt. Die Verbindungen zwischen den Steckern 18 und den Fassungen 22 der Strahlungsquelle 9 sind durch hier nicht dargestellte, flexible Leitungen hergestellt.If the additional housing 19 is inserted with its foot 17 into the opening 15 and the switch 7 is switched on to work with the hot-melt adhesive device according to the second embodiment, the reflector 20 can be pivoted by loosening the knurled screw 26 by means of the knurled knob 25 so that an optimal one The workpiece to be glued is preheated. The connections between the plugs 18 and the sockets 22 of the radiation source 9 are made by flexible lines, not shown here.

Mit der Schmelzklebevorrichtung nach den beiden geschilderten Ausführungsbeispielen ist es möglich, in der Zeit während der die eingeführten Patronen 12 geschmolzen werden oder auch schon früher,das Werkstück durch den Wärmestrahler 6 aufzuheizen. Je nach der Wärmeleitfähigkeit des Werkstücks kann die Vorheizzeit bemessen werden oder, bei sehr schlecht leitendem Material des Werkstücks, ganz entfallen. Die Auführung der Schmelzklebevorrichtung mit dem schwenkbaren Reflektor erschließt zusätzliche Einstellmöglichkeiten.With the hot-melt adhesive device according to the two described exemplary embodiments, it is possible to heat the workpiece by the heat radiator 6 during the time during which the inserted cartridges 12 are melted or even earlier. Depending on the thermal conductivity of the workpiece, the preheating time can be measured or, if the material of the workpiece is very poorly conductive, can be omitted entirely. The listing of the hot melt adhesive device with the swiveling reflector opens up additional setting options.
