In den Figuren 1 und 2 ist ein Klebbanspender 1 dargestellt, der ein Gehäuse 2 mit zwei, im Wesentlichen parallel zueinander angeordneten Gehäusewänden 3, 3' aufweist, von welchen lediglich die Umrisse 4 der vorderen Gehäusewand 3 ersichtlich sind. Ferner ist ein umlaufendes Verbindungsstück 5 zwischen den beiden Gehäusewänden 3, 3' vorgesehen. In den beiden Gehäusewänden 3, 3' ist ein auf je einer Drehachse 7 gelagerte Hebel 8 vorgesehen, der aus zwei L-förmigen Teilen 9, 9' (nur der vordere Teil 9 ersichtlich) und einem oberen Verbindungsstück 10 besteht. Der Hebel 8 weist ferner auf der dem Gehäuse 2 zugewandten Seite eine Nase 11 auf, die zur Mitnahme des Klebbandstreifens dient. In den beiden L-förmigen Teilen 9 ist je ein Stift 12 vorgesehen, der in einer kurzen ersten Kulisse 13 einer dreieckförmigen Zahnstange 14 mit einem kreissektorförmigen Zahnbereich 15 hineingreift. In der unteren Ecke 16 der Zahnstange 14 ist ein Stift 18 befestigt, der in eine längere, bogenförmige Kulisse 20 in der Gehäusewand 3 hineingreift. Eine weitere hier nicht ersichtliche gleiche Zahnstange 14' ist an der gegenüberliegenden Gehäusewand 3' vorgesehen. Der Hebel 8 ist von einer hier nicht weiter dargestellten U-förmigen Spannfeder in der in Figur 1 dargestellten Ausgangsposition gehalten. Diese Spannfeder drückt einerseits mit einem Bein gegen die Unterseite des L-förmigen Teils 9 und liegt mit dem anderen Bein auf einem Vorsprung in der Gehäusewand 3. Selbstverständlich können auch andere Druckfedern, wie Blattfedern, Spiralfedern oder dergleichen zu diesem Zweck vorgesehen sein.FIGS. 1 and 2 show an adhesive dispenser 1 which has a housing 2 with two housing walls 3 arranged essentially parallel to one another, 3 ', of which only the outline 4 of the front housing wall 3 are evident. Furthermore, a peripheral connector 5 between the provided two housing walls 3, 3 '. In the two housing walls 3, 3 ' a lever 8 mounted on a respective axis of rotation 7 is provided, which consists of two L-shaped Parts 9, 9 '(only the front part 9 can be seen) and an upper connecting piece 10 exists. The lever 8 also faces the housing 2 Page a nose 11, which is used to take the tape strip. In the two L-shaped parts 9, a pin 12 is provided, which in a short first link 13 of a triangular rack 14 with a circular sector Tooth area 15 engages. In the lower corner 16 of the rack 14 is a pin 18 attached to a longer, arcuate backdrop 20 in the housing wall 3 reaches into it. Another identical rack 14 'not shown here is provided on the opposite housing wall 3 '. The lever 8 is from a U-shaped tension spring not shown here in the one shown in Figure 1 Starting position held. This tension spring presses on the one hand one leg against the underside of the L-shaped part 9 and lies with the other Leg on a ledge in the housing wall 3. Of course you can also other compression springs, such as leaf springs, spiral springs or the like to this Purpose to be provided.

Ferner sind zwei Transportwalzen 22 und 23 in einem Träger 24 vorgesehen, der aus zwei von Abstandshaltern 25 zusammengehaltenen Seitenteilen 26, 26' besteht. Die beiden, in Achsrichtung geriffelt ausgebildeten Transportwalzen 22 und 23 weisen je seitlich ein Zahnrad 27 und 28 auf, die mit der Zahnstange 14 in Eingriff gelangen können. Ferner sind mehrere als Achse dienende Stifte 29 zwischen den beiden Seitenteilen 26, 26' angeordnet, auf welcher eine Klebbandrolle 30 drehbar gelagert ist. Die Stifte 29 dienen gleichzeitig als Abstandshalter und Verbindung zwischen den Seitenteilen 26, 26'. Der Träger 24 ist als Einschub vorgesehen, so dass dieser ausgetauscht werden kann, nachdem die Klebbandrolle 30 aufgebraucht ist. In der gegenüberliegenden Gehäusewand 3' ist ein als leicht gebogener Hebelarm 32 mit einem als Schneidemittel vorgesehenen, dreieckförmigen Messer 33 auf einer Achse 34 gelagert. Der Hebelarm 32 liegt mit seiner als Steuerkulisse ausgebildeten, unteren Kante 36 auf einem Nocken 37 eines Zahnrades 38, das ebenfalls in der Gehäusewand 3' auf einer Achse 39 gelagert ist. Auf der Innenseite des Zahnrades 38 ist ein Stift 41 vorgesehen, der mittels einer Spannfeder 42 an einem weiteren Stift 43 in der Gehäusewand 3' vorgespannt ist. Wenn das Zahnrad 38 ausser Eingriff der Zahnstange 14' ist (Figur 1), ist die Spannfeder 42 zusammengezogen. Wenn das Zahnrad 38 durch die Zahnstange 14' um etwa 180° gedreht worden ist (Figur 2), ist die Spannfeder 42 in der grössten ausgezogenen Stellung, d.h. das Zahnrad 38 würde wieder in die Ausgangsposition (Figur 1) zurückgehen, wenn es nicht mit der Zahnstange 14' in Eingriff stünde.Furthermore, two transport rollers 22 and 23 are provided in a carrier 24 which from two side parts 26, 26 'held together by spacers 25 consists. The two transport rollers 22, which are corrugated in the axial direction and 23 each have a side gear 27 and 28, which with the rack 14 in Intervention. Furthermore, a plurality of pins 29 serving as axes are between the two side parts 26, 26 'arranged on which an adhesive tape roll 30 is rotatably mounted. The pins 29 also serve as spacers and Connection between the side parts 26, 26 '. The carrier 24 is an insert provided so that it can be replaced after the tape roll 30 is used up. In the opposite housing wall 3 'is a slightly curved lever arm 32 with a triangular provided as cutting means Knife 33 mounted on an axis 34. The lever arm 32 lies with its lower edge 36 designed as a control link on a cam 37 a gear 38, which is also in the housing wall 3 'on an axis 39 is stored. On the inside of the gear 38, a pin 41 is provided by means of a tension spring 42 on a further pin 43 in the housing wall 3 ' is biased. When the gear 38 is out of engagement with the rack 14 '(Figure 1), the tension spring 42 is contracted. If the gear 38 through the rack 14 'has been rotated by about 180 ° (Figure 2), is the tension spring 42 in the largest extended position, i.e. the gear 38 would come back in the starting position (Figure 1) will decrease when it is not with the rack 14 'would be engaged.

In Figur 3 ist die Führung des Klebbandes 45 von der Klebbandrolle 30 ersichtlich (gestrichelte Linie). Die beiden Transportwalzen 22 und 23 werden dabei über ihre Zahnräder 27 und 28 von der Zahnstange 14 in Uhrzeigersinn gedreht, so dass das Klebband 45 durch die zwischen den beiden Transportwalzen 22 und 23 befindlichen Faltwalze 47 längsgefaltet wird. Die zweite Transportwalze 23 weist dabei zwei Ringnuten 48 auf (Figur 4), wodurch in der Mitte eine Kreisscheibe 49 entsteht. Die erste Transportwalze 22 weist nur eine Ringnut 51 auf, die mit der Kreissscheibe 49 übereinstimmt und diese geringfügig überlappend einschliesst. Die Faltwalze 47 weist ihrerseits eine mittige Ringwulst 52 auf, wodurch das Klebband 20 in Längsrichtung zu einer V-Form gefaltet wird. In Figur 3 ist sehr gut der Träger 24 erkennbar, der als Einschub in das Gehäuse 2 ausgebildet ist.The guidance of the adhesive tape 45 from the adhesive tape roll 30 can be seen in FIG (dashed line). The two transport rollers 22 and 23 are on their Gears 27 and 28 rotated clockwise from the rack 14 so that the adhesive tape 45 through the located between the two transport rollers 22 and 23 Folding roller 47 is folded lengthways. The second transport roller 23 has two ring grooves 48 on (Figure 4), whereby a circular disc 49th arises. The first transport roller 22 has only one annular groove 51, which with the Circular disk 49 coincides and includes this slightly overlapping. The folding roller 47 in turn has a central annular bead 52, as a result of which the adhesive tape 20 is folded in the longitudinal direction into a V-shape. In Figure 3 the is very good Carrier 24 can be seen, which is designed as an insert in the housing 2.

In Figur 5 ist nun der Transportvorgang mittels der beiden Transportwalzen 22 und 23 verdeutlicht. In Figur 5a ist der Hebel 8 in der Ausgangsposition, d.h. wird von der Druckfeder nach oben gedrückt (Pfeil A). Die Zahnstange 14 steht dabei ausser Eingriff von den Zahnwalzen 27 und 28 der beiden Transportwalzen 22 und 23. Die Zahnstange 14 ist hier teilweise gestrichelt dargestellt, da der L-förmige Seitenteil 9 des Hebels 8 näher an der - in dieser Figur weggelassenen - Gehäusewand 3 liegt. Wird nun der Hebel 8 nach unten gedrückt (Figur 5b), so wird die Zahnstange 14 durch die Kulissen 13 und 20 mit den beiden Zahnrädern 27 und 28 in Eingriff gebracht, wodurch die Transportwalzen 22 und 23 in Uhrzeigersinn gedreht und das Klebband 45 transportiert wird. Wenn der Hebel 8 ganz nach unten gedrückt ist, steht die Zahnstange 14 immer noch in Eingriff mit den Zahnrädern 27 und 28. Erst wenn der Hebel 8 losgelassen und durch die Druckfeder nach oben bewegt wird, kommt die Zahnstange 14 ausser Eingriff von den Zahnrädern 27 und 28, d.h. die Zahnräder 27 und 28 stehen still und das Klebband 45 wird nicht mehr weiter transportiert. Bei der Bewegung des Hebels 8 von oben (Figur 5a) nach unten (Figur 5c) wird somit ein genau definierte Länge Klebband oder Streifen von den Transportwalzen 22 und 23 transportiert. Der Hebel 8 kann aber auch in der Zwischenposition (Figur 5b) schon losgelassen werden, wodurch die Zahnstange 14 ausser Eingriff der Zahnräder 27 und 28 gelangt. Wenn der Hebel 8 wieder nach unten gedrückt werden, wird somit ein längerer Streifen Klebband erzeugt. Durch mehrmaliges Hebeln kann somit ein Streifen beliebiger Länge erhalten werden.The transport process by means of the two transport rollers 22 is now in FIG and 23 clarifies. In Figure 5a the lever 8 is in the starting position, i.e. becomes pushed up by the compression spring (arrow A). The rack 14 stands there disengaged from the toothed rollers 27 and 28 of the two transport rollers 22 and 23. The rack 14 is shown here partly in dashed lines, since the L-shaped one Side part 9 of the lever 8 closer to the - omitted in this figure - Housing wall 3 is. If the lever 8 is now pressed down (Figure 5b), so the rack 14 through the scenes 13 and 20 with the two gears 27 and 28 engaged, causing the transport rollers 22 and 23 clockwise rotated and the adhesive tape 45 is transported. When the lever 8 is all the way is pushed down, the rack 14 is still engaged with the Gears 27 and 28. Only when the lever 8 is released and by the compression spring is moved upward, the rack 14 is disengaged from the Gears 27 and 28, i.e. the gears 27 and 28 stand still and the adhesive tape 45 is no longer transported. When moving the lever 8 of Above (Figure 5a) down (Figure 5c) is thus a precisely defined length of adhesive tape or strips transported by the transport rollers 22 and 23. The lever 8 can also be released in the intermediate position (Figure 5b), whereby the rack 14 comes out of engagement of the gears 27 and 28. If the lever 8 is pressed down again, it will be a longer one Strips of adhesive tape are generated. A strip can be created by levering several times any length can be obtained.

In Figur 6 ist sodann der Schneidevorgang in weiteren Einzelheiten dargestellt. Ähnlich wie die Zahnstange 14 wird hier die Zahnstange 14' vom Hebel 8 nach unten bewegt. Wie ersichtlich weist die Zahnstange 14' nur im unteren Bereich Zähne auf, die in Eingriff mit dem Zahnrad 38 gelangen können. In der untersten Position (Figur 6c) stehen die Zähne der Zahnstange 14' jedoch immer noch mit dem Zahnrad 38 in Eingriff, so dass die Spannfeder 42 voll gespannt ist. Wenn der Hebel 8 nun losgelassen wird, dreht sich das Zahnrad 38 mit dem Nocken 37 weiter in Uhrzeigersinn und springt der Hebelarm 32 mit dem dreieckförmigen Messer 33 nach oben, wodurch ein Streifen vom Klebband 45 abgetrennt wird (Figur 6d). Da das Klebband 45 vorher durch dir Faltwalze 47 V-förmig gefaltet worden ist, ergibt sich beim abgeschnittenen Streifen ein gerader Abschnitt. Wenn nun der Hebel 8 in der Zwischenposition (Figur 6b) losgelassen wird, kann der Hebelarm 32 nicht zurückspringen, weil das Zahnrad 38 und somit der Nocken 37 wieder zurückgedreht werden, so dass noch kein Streifen abgeschnitten wird. Damit kann durch das Zusammenwirken von Transportwalzen 22 und 23 und das nicht betätigte Messer 33 die Länge des Streifens ab einer minimalen Länge (einem Schlag) selbst bestimmt werden. Wie schon in Zusammenhang mit Figur 5 erklärt, kann die Zahnstange 14' jedoch auch über die ganze Länge Zähne aufweisen. Die Zahnstangen 14 und 14' können andererseits auch mit den L-förmigen Teilen 9 und 9' einstückig ausgebildet sein, wobei dann der Stift 12 und die erste Kulisse 13 entfallen.The cutting process is then shown in further detail in FIG. Similar to the toothed rack 14, the toothed rack 14 ′ is moved from the lever 8 here moved down. As can be seen, the rack 14 'only has in the lower region Teeth that can come into engagement with the gear 38. In the bottom Position (Figure 6c), the teeth of the rack 14 'are still with the gear 38 in engagement so that the tension spring 42 is fully tensioned. If the lever 8 is now released, the gear 38 rotates with the cam 37 further clockwise and the lever arm 32 jumps with the triangular Knife 33 upwards, whereby a strip is separated from the adhesive tape 45 (Figure 6d). Since the adhesive tape 45 previously folded by you folding roller 47 in a V-shape a straight section results when the strip is cut off. If now the lever 8 is released in the intermediate position (Figure 6b), the Do not spring back the lever arm 32 because the gear 38 and thus the cam 37 be turned back so that no strip is cut off yet. This can by the interaction of transport rollers 22 and 23 and that knife 33 not actuated the length of the strip from a minimum length (one blow) be determined by yourself. As already in connection with Figure 5 explained, the rack 14 'can also have teeth over the entire length. The racks 14 and 14 ', on the other hand, can also be with the L-shaped ones Parts 9 and 9 'can be formed in one piece, in which case the pin 12 and the first backdrop 13 is omitted.

Es versteht sich für den Fachmann, dass der oben beschriebene Klebbandspender 1 nur sehr wenige Einzelteile aufweist, was enorme Material- und Kosteneinsparungen bedeutet. Ein weiterer Vorteil dieses Klebbandspenders 1 ist, dass die wesentlichen Teile wie Gehäuse 2 mit Hebel 8 und Schneidemittel 33 weiter verwendet werden können und lediglich der Einschub oder Träger 24 mit der Klebbandrolle 30 ausgetauscht werden muss. Dadurch ergibt sich eine weitere Verringerung der Umweltbelastung. Ausserdem können die Einschübe oder Träger 24 rezykliert werden. It is understood by those skilled in the art that the adhesive tape dispenser described above 1 has very few individual parts, which means enormous material and cost savings means. Another advantage of this adhesive tape dispenser 1 is that the essential parts such as housing 2 with lever 8 and cutting means 33 continue to be used and only the insert or carrier 24 with the adhesive tape roll 30 needs to be replaced. This results in a further reduction the environmental impact. In addition, the inserts or supports 24 be recycled.
