The device imparts a rotating or vibrating motion to the substance to generate mechanical friction between the meltable substance and the substrate, causing the substrate to melt and apply to the substrate.

Description

Die Erfindung betrifft eine Vorrichtung zum Auftragen eines durch Erwärmen auftragbaren festen Stoffes, insbesondere eines Schmelzklebers, auf ein Substrat mit einem Gehäuse, welches eine nach außen offene Aufnahme für den festen Stoff aufweist, welche mit einem im Gehäuse angeordneten, in Dreh- und/oder Schwingbewegung bringbaren Element verbunden ist.The invention relates to a device for applying a coatable by heating solid material, in particular a hot melt adhesive, to a substrate having a housing which has an outwardly open receptacle for the solid material, which arranged with a housing in rotation and / or Swinging motion-engageable element is connected.

Vorrichtungen zum Auftragen von festen Schmelzklebern oder dgl. (beispielsweise Low- oder Hot-Melt-Schmelzkleber) auf Substrate sind in unterschiedlichen Ausführungsformen bekannt. So werden häufig sogenannte Klebepistolen verwandt, die in verschiedenen Ausgestaltungen bekannt sind. Diese Vorrichtungen weisen dabei innerhalb des Gehäuses eine Aufnahme für den Schmelzkleber auf, der in fester Form stabförmig in die Vorrichtung eingegeben wird. Wenigstens der vordere Abgabebereich der Vorrichtung, welcher den Schmelzkleber umgibt, ist mit einer Heizeinrichtung ausgerüstet, mit welcher der Schmelzkleber vor der Anwendung auf die Schmelztemperatur (je nach Klebstoff zwischen 60 °C bis 80 °C (Low-Melt) oder 180 °C bis 220 °C (Hot-Melt)) erwärmt wird und dann im fließfähigen Zustand auf das Substrat aufgebracht werden kann. Neben diesen gängigen Heißschmelzkleberpistolen sind auch Vorrichtungen mit Heizeinrichtung bekannt, die es ermöglichen, den aufgeschmolzenen Kleber zu versprühen.Devices for applying solid hot melt adhesives or the like (for example, low-melt or hot-melt hot melt adhesives) to substrates are known in various embodiments. So often called glue guns are used, which are known in various configurations. These devices have within the housing a receptacle for the hot melt adhesive, which is entered in a solid form in the form of a rod in the device. At least the front delivery area of the apparatus surrounding the hotmelt adhesive is equipped with a heater which allows the hotmelt adhesive to reach the melting temperature prior to application (between 60 ° C to 80 ° C (low-melt) or 180 ° C to 100 ° C depending on the adhesive 220 ° C (hot-melt)) is heated and then applied in a flowable state to the substrate. In addition to these common hot-melt glue guns, devices with a heating device are known, which make it possible to spray the molten adhesive.

Allen diesen bekannten Vorrichtungen ist jedoch gemeinsam, daß sie eine Heizeinrichtung benötigen, mit der der Klebstoff zumindest angeschmolzen oder ggf. sogar verflüssigt werden kann, um ihn anschließend aufzutragen oder zu versprühen, Eine solche Heizeinrichtung ist zum einen aufwendig und benötigt eine nicht unbeachtliche Heizenergie, zum anderen ist die Vorrichtung erst nach einer gewissen Aufheizzeit arbeitsfähig, d.h. erst dann, wenn eine genügende Menge Schmelzkleber aufgeschmolzen ist.All these known devices, however, have in common that they require a heater with which the adhesive can be at least fused or possibly even liquefied to subsequently apply or spray it. Such a heater is complex and requires a not inconsiderable heating energy, on the other hand, the device is only able to work after a certain heating time, ie only when a sufficient amount of hot melt adhesive has melted.

Hinweise auf andere Aufbringarten von schmelzbaren Stoffen geben auch die dem Oberbegriff entsprechenden GB1578433A und GB2025793A . Hier wird die benötigte Wärmeenergie zum Schmelzen des Stoffes über äußere Reibung, beispielsweise mittels oszillierender oder drehender Bewegung bereitgestellt.References to other types of application of fusible substances also give the corresponding to the preamble GB1578433A and GB2025793A , Here, the heat energy required for melting the substance is provided by external friction, for example by means of oscillating or rotating movement.

Aufgabe der Erfindung ist es, eine eigenständige Vorrichtung zum Auftrag eines Schmelzklebstoffes über eine Dreh- und/oder Schwingbewegung zu schaffen.The object of the invention is to provide an independent device for applying a hot melt adhesive via a rotary and / or swinging motion.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is solved by the features of the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Der Grundgedanke der Erfindung ist der Einsatz einer Vorrichtung zum Auftragen eines durch Erwärmen auftragbaren festen Stoffes, mit einem Gehäuse, wobei die Erwärmung des Stoffes durch eine Dreh- und/oder Schwingbewegung hervorgerufen wird, die von einem innerhalb des Gehäuses angeordneten Dreh- und/oder Schwingantrieb ausgeht.The basic idea of the invention is the use of a device for applying a solid which can be applied by heating, with a housing, wherein the heating of the substance is caused by a rotational and / or oscillatory movement, which is determined by a rotary and / or Vibration drive runs out.

Erfindungsgemäß weist das Gehäuse eine nach außen offene Aufnahme für den festen Stoff, insbesondere einen Schmelzklebstoff, auf. Der Stoff ist dabei mit einem im Gehäuse angeordneten, in Dreh- und/oder Schwingbewegung bringbaren Element verbunden, welches wiederum über den oben genannten Dreh- und/oder Schwingantrieb, welcher innerhalb des Gehäuses angeordnet ist, angetrieben wird.According to the invention, the housing has an outwardly open receptacle for the solid material, in particular a hotmelt adhesive. The substance is in this case connected to an element arranged in the housing, capable of being brought into rotary and / or oscillatory motion, which in turn is driven by means of the abovementioned rotary and / or oscillatory drive, which is arranged inside the housing.

Derartige Dreh- und/oder Schwingantriebe sind hinlänglich bekannt und verfügbar und können somit problemlos für die erfindungsgemäße Vorrichtung verwendet werden.Such rotary and / or oscillating drives are well known and available and can thus be used without problems for the device according to the invention.

Durch die Dreh- und/oder Schwingbewegung des zu schmelzenden Stoffes über den Dreh- und/oder Schwingantrieb kann äußere Reibung an dem Stoff erzeugt werden, welche den Stoff zum Schmelzen bringt, so dass ein Auftrag des Stoffes auf ein Substrat möglich wird. Die Reibung und damit die zum Schmelzen des festen Stoffes benötigte Wärme kann durch ein Versetzen des Abgabeendes des festen Stoffes in eine Dreh- und/oder Schwingbewegung und ein Drücken gegen das Substrat erreicht werden. Auf diese Weise kann der feste Stoff am Abgabeende aufgeschmolzen und in geschmolzenem Zustand auf das Substrat aufgebracht werden.By the rotational and / or oscillating movement of the material to be melted via the rotary and / or oscillatory drive, external friction can be generated on the substance, which causes the substance to melt, so that an application of the substance on a substrate is possible. The friction, and thus the heat needed to melt the solid, can be achieved by offsetting the delivery end of the solid into a rotational and / or oscillating motion and pressing against the substrate. In this way, the solid material can be melted at the discharge end and applied to the substrate in a molten state.

In Abkehr von bisherigen Vorrichtungen dieser Art weist die erfindungsgemäße Vorrichtung somit keine Heizeinrichtung auf, so daß auch keine Heizenergie und lange Aufheizzeiten benötigt werden. Die Vorrichtung ist vielmehr sofort zur Verarbeitung bzw. zum Auftragen von Schmelzklebern oder dgl. einsatzbereit. Bei Inbetriebnahme der Vorrichtung wird die Aufnahme für den Schmelzkleber und damit auch der Schmelzkleber in eine Dreh- und/oder Schwingbewegung versetzt und das vordere Abgabeende des Schmelzklebers auf das zu beschichtende Substrat aufgedrückt, wodurch aufgrund der Dreh- und/oder Schwingbewegung mechanische Reibung entsteht, die zwangsläufig Wärme erzeugt, was zum Aufschmelzen des vorderen Endes des Schmelzklebers und zum Auftragen desselben auf das Substrat führt. Eine solche Vorrichtung ist äußerst leicht zu bedienen und der Schmelzkleber kann leicht aufgebracht und verteilt werden.In departure from previous devices of this type, the device according to the invention thus has no heating device, so that no heating energy and long heating times are needed. Rather, the device is ready for use immediately for processing or for applying hot melt adhesives or the like. When the device is put into operation, the receptacle for the hotmelt adhesive and thus also the hotmelt adhesive are put into a rotating and / or oscillating motion and the front discharge end of the hotmelt adhesive is pressed onto the substrate to be coated, whereby mechanical friction arises due to the rotational and / or oscillating movement, which inevitably generates heat, resulting in the melting of the front end of the hot melt adhesive and the application of the same to the substrate. Such a device is extremely easy to use and the hot melt adhesive can be easily applied and distributed.

Dabei ist ganz besonders bevorzugt vorgesehen, daß der Dreh- und/oder Schwingantrieb als elektrischer Dreh- und/oder Schwingantrieb ausgebildet ist. Grundsätzlich sind auch andere Dreh- und/oder Schwingantriebe einsetzbar, beispielsweise pneumatisch oder hydraulisch.It is very particularly preferably provided that the rotary and / or oscillating drive is designed as an electric rotary and / or oscillatory drive. In principle, other rotary and / or oscillatory drives are used, for example pneumatically or hydraulically.

Ein weiterer Vorteil ist der Einsatz einer in das Gehäuse integrierten Stromversorgung für den Dreh- und/oder Schwingantrieb. Dabei ist beispielsweise der Einsatz von Akkus oder Batterien denkbar. Bei dieser Ausgestaltung ist die Vorrichtung völlig unabhängig von irgendwelchen Stromanschlüssen und kann deshalb an jedem Ort problemlos eingesetzt werden.Another advantage is the use of an integrated power supply in the housing for the rotary and / or oscillating drive. For example, the use of rechargeable batteries or batteries is conceivable. In this embodiment, the device is completely independent of any power connections and can therefore be used easily anywhere.

Besonders geeignet für eine solche Vorrichtung ist ein Schmelzkleber, welcher dadurch gekennzeichnet ist, daß er sich durch eine innere oder äußere Reibung aktivieren läßt, wie in EP 96/02194 beschrieben und auf die diesbezüglich Bezug genommen werden kann.Particularly suitable for such a device is a hot melt adhesive, which is characterized in that it is characterized by an internal or external friction activate, as in EP 96/02194 and to which reference can be made.

Die Reibung sollte so groß sein, daß bei der Haftreibung eine Filmdicke von 2 bis 200 µm, insbesondere von 10 bis 100 µm bei einmaligem Überstreichen des Substrates mit dem Klebstoff in einer Geschwindigkeit von 1 bis 500 cm/sec, bevorzugt 2 bis 100 cm/sec, bei einem Druck von 1 kPa bis 10 MPa, bevorzugt 5 kPa bis 5 MPa, vorzugsweise 10 kPa bis 1,0 MPa, erzielt wird. Diese Werte gelten für Normalbedingungen (20 °C und 50 % relativer Luftfeuchtigkeit) sowie für ein Papier folgender Qualität: 5015 Spezial Copier der Fa. Soennecken.The friction should be so great that in the static friction a film thickness of 2 to 200 .mu.m, in particular from 10 to 100 microns with a single sweeping the substrate with the adhesive at a rate of 1 to 500 cm / sec, preferably 2 to 100 cm / sec, at a pressure of 1 kPa to 10 MPa, preferably 5 kPa to 5 MPa, preferably 10 kPa to 1.0 MPa. These values are valid for normal conditions (20 ° C and 50% relative humidity) as well as for a paper of the following quality: 5015 Spezial Copier from Soennecken.

Dabei wurde folgende Arbeitshypothese angenommen:The following working hypothesis was adopted:

Die kristallinen Bereiche werden durch die mechanische Einwirkung der Reibung in eine amorphe Form überführt. Diese amorphe Form erzeugt die Klebrigkeit. Solange der Klebstoff nicht rekristallisiert, bleibt er haftklebrig. Nach der Rekristallisation verliert der Klebstoff seine Klebrigkeit und gewinnt seine endgültige Festigkeit.The crystalline regions are converted by the mechanical action of the friction in an amorphous form. This amorphous form creates the stickiness. As long as the adhesive does not recrystallise, it remains tacky. After recrystallization, the adhesive loses its stickiness and gains its final strength.

Dieser besonders geeignete Klebstoff besteht aus 25 bis 100, insbesondere 30 bis 99 und vorzugsweise aus 60 bis 98 Gew.-%, mindestens eines Bindemittels und aus 0 bis 75, insbesondere aus 0,1 bis 70 und vorzugsweise aus 0,5 bis 40 Gew.-% an Zusätzen. Das Bindemittel ist gleichzeitig die formgebende Substanz. Die Zusätze dienen in erster Linie dazu, die Kristallisation, die Klebrigkeit und das Abriebverhalten zu beeinflussen. Darüber hinaus können sie aber auch die üblichen Funktionen erfüllen, nämlich stabilisieren, konservieren, färben usw..This particularly suitable adhesive consists of 25 to 100, in particular 30 to 99 and preferably from 60 to 98 wt .-%, at least one binder and from 0 to 75, in particular from 0.1 to 70 and preferably from 0.5 to 40 wt .-% of additives. The binder is also the formative substance. The additives serve primarily to influence the crystallization, the stickiness and the abrasion behavior. In addition, they can also perform the usual functions, namely stabilize, preserve, dye, etc ..

Neben diesem beschriebenen Klebstoff können auch andere Schmelzkleber zum Einsatz kommen, insbesondere dann wenn sie die dort beschriebenen Voraussetzungen bezüglich Kristallisations-Temperatur, -Grad und -Geschwindigkeit erfüllen.In addition to this described adhesive, other hotmelt adhesives can also be used, in particular if they meet the conditions described there with regard to crystallization temperature, degree and speed.

Die Erfindung ist nachstehend anhand der Zeichnung beispielhaft näher erläutert. Diese zeigt in der einzigen Figur in stark vereinfachter Darstellung eine erfindungsgemäße Vorrichtung.The invention is explained in more detail below by way of example with reference to the drawing. This shows in the single figure in a greatly simplified representation of a device according to the invention.

Eine in der Zeichnung dargestellte erfindungsgemäße Vorrichtung dient zum Auftragen eines durch Erwärmen auftragbaren festen Stoffes auf ein Substrat. Dabei handelt es sich bevorzugt um einen Schmelzkleber, beispielsweise einen Low-Melt- oder einen Hot-Melt-Schmelzkleber, deren Schmelztemperaturen zwischen 60 °C bis 80 °C bzw. 180 °C bis 220 °C liegen.A device according to the invention shown in the drawing is used for applying a coatable by heating solid material on a substrate. This is preferably a hotmelt adhesive, for example a low-melt or hot-melt hotmelt adhesive whose melting temperatures are between 60.degree. C. to 80.degree. C. or 180.degree. C. to 220.degree.

Die Vorrichtung weist zunächst ein Gehäuse 1 auf, in das vorzugsweise eine nicht dargestellte Stromversorgung, beispielsweise in Form von Akkus oder Batterien integriert ist, dazu ist das Gehäuse 1 an geeigneter Stelle öffen- und verschließbar ausgebildet.The device initially has a housing 1, in which preferably a not shown power supply, for example in the form of rechargeable batteries or batteries is integrated, to the housing 1 is openable and closable formed at a suitable location.

Aus dem vorderen Ende des Gehäuses 1 ragt eine rohrförmige Aufnahme 3 heraus, in die der aufzutragende Schmelzkleber in Form eines festen Schmelzkleberstiftes bzw, Stabes 4 eingesetzt ist. Dabei ist die rohrförmige Aufnahme 3 vorzugsweise so ausgebildet, daß der Schmelzkleber 4 in Betätigungsposition der Vorrichtung immer ein Stück weit nach vorne aus der Aufnahme 3 hinaussteht, wie dies in der Zeichnung dargestellt ist. Dies kann auf unterschiedliche Weise realisiert werden, vorzugsweise mit einer Vorrichtung, die den festen Klebstoff mittels einer am hinteren Ende angebrachten Feder gegen die vordere Austrittsöffnung drückt. Da der Durchmesser der Austrittsöffnung kleiner als der Durchmesser des festen Klebstoffes ist, wird er erst herausgeschoben, wenn die Erweichungstemperatur auf dem vorderen Ende des sonst festen Klebstoffes erreicht ist.From the front end of the housing 1 protrudes a tubular receptacle 3, in which the hot melt adhesive to be applied in the form of a solid hot melt adhesive pin or rod 4 is inserted. In this case, the tubular receptacle 3 is preferably formed so that the hot melt adhesive 4 in the operating position of the device is always a bit far out of the receptacle 3, as shown in the drawing. This can be realized in different ways, preferably with a device that presses the solid adhesive against the front outlet opening by means of a spring attached to the rear end. Since the diameter of the outlet opening is smaller than the diameter of the solid adhesive, it is pushed out only when the softening temperature is reached on the front end of the otherwise solid adhesive.

Wesentlich für die erfindungsgemäße Vorrichtung ist nun, daß die rohrförmige Aufnahme 3 mit einem im Gehäuse 1 angeordneten, in Dreh- und/oder Schwingbewegung bringbaren Element 2 verbunden ist, d.h. beim Ausführungsbeispiel in dieses Element 2 eingesetzt ist. Dieses Element 2 ist dabei mit einem Dreh- und/oder Schwingantrieb verbunden, der nicht dargestellt ist, der aber erfindungsgemäß innerhalb des Gehäuses 1 angeordnet ist. Dieser Dreh- und/oder Schwingantrieb ist bevorzugt elektrisch ausgebildet und mit der in das Gehäuse 1 integrierten Stromversorgung verbunden.Essential for the device according to the invention is now that the tubular receptacle 3 is arranged with a housing 1, in turn and / or oscillatory movement engageable element 2 is connected, that is used in the embodiment in this element 2. This element 2 is connected to a rotary and / or oscillating drive, which is not shown, but which is arranged according to the invention within the housing 1. This rotary and / or oscillating drive is preferably designed electrically and connected to the power supply integrated in the housing 1.

Durch Betätigung des Dreh- und/oder Schwingantriebes wird das Element 2 in eine Dreh- oder eine Schwingbewegung oder auch in eine kombinierte Dreh-/Schwingbewegung versetzt. Diese Bewegung überträgt sich auf die mit dem Element 2 fest verbundene Aufnahme 3 und damit auf den Schmelzkleber 4, Die Vorrichtung wird nun mit drehender und/oder schwingender Klebstoffspitze auf das mit Klebstoff zu beschichtende Substrat gedrückt, wodurch aufgrund der Bewegung der Klebstoffspitze gegenüber dem Substrat mechanische Reibung erzeugt wird, die zu einer Erwärmung führt. Diese Wärme dient zum Aufschmelzen der Klebstoffspitze, welche dadurch leicht auf das Substrat aufgebracht und verteilt werden kann.By actuating the rotary and / or oscillating drive, the element 2 is set in a rotary or a swinging motion or in a combined rotary / oscillating motion. This movement is transferred to the receptacle 3 fixedly connected to the element 2 and thus to the hotmelt adhesive 4. The device is then pressed onto the adhesive-coated substrate with rotating and / or oscillating adhesive tip, whereby due to the movement of the adhesive tip relative to the substrate mechanical friction is generated, which leads to a warming. This heat is used to melt the adhesive tip, which can thereby be easily applied to the substrate and distributed.

Offensichtlich ist die Vorrichtung sofort betriebsbereit. Aufheizzeiten oder dgl., die die Betriebsbereitschaft der Vorrichtung einschränken könnten, sind nicht vorhanden.Obviously, the device is ready for immediate use. Heating times or the like., Which could limit the operational readiness of the device are not present.

Natürlich ist die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt. Weitere Ausgestaltungen sind möglich, ohne den Grundgedanken zu verlassen. So kann der Dreh- und/oder Schwingantrieb auch hydraulisch oder pneumatisch ausgebildet sein.Of course, the invention is not limited to the illustrated embodiment. Further embodiments are possible without departing from the basic idea. Thus, the rotary and / or oscillating drive can also be designed hydraulically or pneumatically.
