Description

Vorrichtung zur streifenweisen Abgabe von KlebbandDevice for dispensing adhesive tape in strips
Die Erfindung betrifft eine Vorrichtung zur streifenweisen Abgabe von Klebband oder dergleichen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for dispensing adhesive tape or the like in strips according to the preamble of patent claim 1.
Eine solche Vorrichtung ist beispielsweise aus US-A-5,207,860 bekannt. Diese weist einen Hebel auf, der mindestens zwei bogenförmige Zahnstangen aufweist, die in verschiedene Zahnräder eingreifen. Sie weist eine grosse Anzahl an Einzelteilen auf. Der Hebel ist auf einer Achse drehbar gelagert und über Stifte mit den Zahnstangen verbunden. Mittels eines relativ komplizierten Getriebes und verschiedener Spann- und Blattfedern wird eine Schneideeinrichtung betätigt. Durch die einseitige Lagerung der Zahnstangen seitlich des Hebels, ergibt sich ein leichtes Drehmoment auf die Achse des Hebels, so dass ein Verklemmen der Zahnstangen bei der Abwärtsbewegung des Hebels nicht ausgeschlossen ist. Ferner ist die oben beschriebene Vorrichtung relativ voluminös, weshalb sie in der Praxis schwer zu handhaben ist.Such a device is known for example from US-A-5,207,860. This has a lever which has at least two arc-shaped toothed racks which engage in different toothed wheels. It has a large number of individual parts. The lever is pivoted on an axis and connected to the racks by pins. A cutting device is actuated by means of a relatively complicated gear and various tension and leaf springs. Due to the one-sided mounting of the racks on the side of the lever, there is a slight torque on the axis of the lever, so that jamming of the racks during the downward movement of the lever is not excluded. Furthermore, the device described above is relatively bulky, which is why it is difficult to handle in practice.
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung zur Abgabe von Klebband zu gestalten, der aus wesentlich weniger Einzelteilen gefertigt ist und eine leichtere Bedienung ermöglicht.The present invention is based on the object of designing a device for dispensing adhesive tape which is made from considerably fewer individual parts and which enables easier operation.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a device with the features of claim 1.
Die erfindungsgemässe Vorrichtung hat den grossen Vorteil, dass sie sehr kompakt und besonders leicht zu bedienen ist.

In den Figuren sind für dieselben Elemente jeweils dieselben Bezugszeichen verwendet worden und erstmalige Erklärungen betreffen alle Figuren, wenn nicht ausdrücklich anders erwähnt.In the figures, the same reference numerals have been used for the same elements, and first-time explanations apply to all figures, unless expressly stated otherwise.
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. Femer 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-förmi- gen Teilen 9, 9' (nur der vordere Teil 9 ersichtlich) und einem oberen Verbin- dungsstück 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 kreissektorför- migen 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 dar- gestellten 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.1 and 2 show an adhesive dispenser 1 which has a housing 2 with two housing walls 3, 3 'arranged essentially parallel to one another, of which only the outlines 4 of the front housing wall 3 can be seen. A circumferential connecting piece 5 is also provided between the two housing walls 3, 3 '. Provided in the two housing walls 3, 3 'is a lever 8 which is mounted on a respective axis of rotation 7 and which consists of two L-shaped parts 9, 9' (only the front part 9 can be seen) and an upper connection piece 10 exists. The lever 8 also has a nose 11 on the side facing the housing 2, which is used to take the strip of adhesive tape with it. A pin 12 is provided in each of the two L-shaped parts 9 and engages in a short first link 13 of a triangular rack 14 with a tooth sector 15 in the form of a circular sector. In the lower corner 16 of the rack 14, a pin 18 is attached, which engages in a longer, arcuate backdrop 20 in the housing wall 3. Another identical rack 14 ', not shown here, is provided on the opposite housing wall 3'. The lever 8 is held in the starting position shown in FIG. 1 by a U-shaped tension spring (not shown here). This tension spring presses with one leg against the underside of the L-shaped part 9 and lies with the other leg on a projection in the housing wall 3. Of course, other compression springs such as leaf springs, coil springs or the like can also be provided for this purpose.
Ferner sind zwei Transportwalzen 22 und 23 in einem Träger 24 vorgesehen, der aus zwei von Abstandshaitem 25 zusammengehaltenen Seitenteilen 26, 26' besteht. Die beiden, in Achsrichtung geriffelt ausgebildeten Transportwaizen 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 Klebband- rolle 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 consists of two side parts 26, 26 'held together by spacers 25. The two transport rollers 22 and 23, which are corrugated in the axial direction, each have a toothed wheel 27 and 28 on the side, which can engage with the toothed rack 14. Furthermore, a plurality of pins 29 serving as axes are arranged between the two side parts 26, 26 ', on which an adhesive tape roll 30 is rotatably mounted. The pins 29 also serve as a spacer and connection between the side parts 26, 26 '. The carrier 24 is provided as an insert so that it can be exchanged after the adhesive tape roll 30 has been used up. In the opposite housing wall 3 ', a slightly curved lever arm 32 is mounted on an axis 34 with a triangular knife 33 provided as a cutting means. The lever arm 32, with its lower edge 36 designed as a control link, rests on a cam 37 of a gear wheel 38, which is also mounted in the housing wall 3 'on an axis 39. A pin 41 is provided on the inside of the gear 38, which pin is connected to a further pin 43 in the housing wall 3 'by means of a tension spring 42. is biased. When the gear 38 is disengaged from the rack 14 '(Figure 1), the tension spring 42 is contracted. When the gear 38 has been rotated by the rack 14 'by about 180 ° (Figure 2), the tension spring 42 is in the largest extended position, ie the gear 38 would return to the starting position (Figure 1) if it was 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 Transportwaizen 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.In Figure 3, the guidance of the adhesive tape 45 from the adhesive tape roll 30 can be seen (dashed line). The two transport rollers 22 and 23 are rotated clockwise by their toothed wheels 27 and 28 from the rack 14 so that the adhesive tape 45 is folded lengthwise by the folding roller 47 located between the two transport rollers 22 and 23. The second transport roller 23 has two annular grooves 48 (Figure 4), whereby a circular disc 49 is formed in the middle. The first transport roller 22 has only one annular groove 51, which corresponds to the circular disk 49 and encloses it 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 into a V-shape in the longitudinal direction. The carrier 24, which is designed as an insert in the housing 2, can be seen very clearly in FIG.
In Figur 5 ist nun der Transportvorgang mittels der beiden Transportwalzen 22 und 23 verdeutlicht. In Figur 5a ist der Hebe! 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-för- mige 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 Druck- feder 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 Kleb- band oder Streifen von den Transportwaizen 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 iängerer 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 and 23 is now illustrated in FIG. In Figure 5a is the lifting! 8 in the starting position, ie is pushed up by the compression spring (arrow A). The toothed rack 14 is disengaged from the toothed rollers 27 and 28 of the two transport rollers 22 and 23. The toothed rack 14 is shown here partly in broken lines, since the L-shaped side part 9 of the lever 8 is closer to the - omitted in this figure - Housing wall 3 is. If the lever 8 is now pressed down (FIG. 5b), the rack 14 is brought into engagement with the two gearwheels 27 and 28 through the links 13 and 20, as a result of which the transport rollers 22 and 23 are rotated clockwise and the adhesive tape 45 is transported . When the lever 8 is pushed all the way down, the rack 14 is still in engagement with the gears 27 and 28. Only when the lever 8 is released and pressed by the spring is moved upward, the rack 14 disengages from the gears 27 and 28, ie the gears 27 and 28 stand still and the adhesive tape 45 is no longer transported. When the lever 8 moves from above (FIG. 5a) downwards (FIG. 5c), a precisely defined length of adhesive tape or strip is thus transported by the transport rollers 22 and 23. The lever 8 can, however, also be released in the intermediate position (FIG. 5b), as a result of which the toothed rack 14 is disengaged from the gears 27 and 28. When the lever 8 is pressed down again, a longer strip of adhesive tape is produced. A strip of any length can be obtained by levering it several times.
In Figur 6 ist sodann der Schπeidevorgang 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 Transportwaizen 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 auf- weisen. Die Zahnstangen 14 und 14' können andererseits auch mit den L-förmi- gen 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 more detail in FIG. Similar to the rack 14, the rack 14 'is moved downwards by the lever 8 here. As can be seen, the toothed rack 14 ′ has teeth only in the lower region, which can come into engagement with the toothed wheel 38. In the lowest position (FIG. 6c), however, the teeth of the rack 14 'are still in engagement with the gear 38 so that the tension spring 42 is fully tensioned. When the lever 8 is now released, the gear 38 rotates clockwise with the cam 37 and the lever arm 32 jumps upwards with the triangular knife 33, as a result of which a strip is separated from the adhesive tape 45 (FIG. 6d). Since the adhesive tape 45 has previously been folded in a V-shape by the folding roller 47, a straight section results when the strip is cut off. If the lever 8 is now released in the intermediate position (FIG. 6b), the lever arm 32 cannot spring back because the gear 38 and thus the cam 37 are turned back again, so that no strip is cut off yet. With the interaction of transport rollers 22 and 23 and the knife 33 not actuated, the length of the strip can itself be determined from a minimum length (one stroke). As already explained in connection with FIG. 5, the toothed rack 14 'can also have teeth over the entire length. The racks 14 and 14 ', on the other hand, can also be used with the L-shaped gene parts 9 and 9 'be integrally formed, in which case the pin 12 and the first link 13 are omitted.
Es versteht sich für den Fachmann, dass der oben beschriebene Klebbandspen- der 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 Verrin- gerung der Umweltbelastung. Ausserdem können die Einschübe oder Träger 24 rezykliert werden. It is understood by the person skilled in the art that the adhesive tape dispenser 1 described above has only very few individual parts, which means enormous material and cost savings. Another advantage of this adhesive tape dispenser 1 is that the essential parts such as housing 2 with lever 8 and cutting means 33 can continue to be used and only the insert or carrier 24 with the adhesive tape roll 30 has to be exchanged. This results in a further reduction in environmental pollution. In addition, the inserts or carriers 24 can be recycled.
