Description
Die Erfindung betrifft einen Etikettendrucker zum Bedrucken von selbstklebenden trägerlosen Endlosband-Etiketten mit einem Druckkopf und einer angetriebenen Druckwalze, wobei die Endlosband-Etiketten entlang einer Etikettenbahn zwischen dem Druckkopf und der Druckwalze hindurchführbar sind, und einem der Druckwalze in Transportrichtung der Endlosband-Etiketten nachgeschalteten Abstreifelement zum Abstreifen der Etiketten von der Druckwalze.The invention relates to a label printer for printing self-adhesive, carrier-free endless tape labels with a print head and a driven print roller, the endless tape labels being able to be guided along a label web between the print head and the print roller, and a stripping element downstream of the print roller in the transport direction of the endless tape labels for stripping the labels from the print roller.
Ein derartiger Etikettendrucker ist aus dem Dokument
Bei der Druckwalze handelt es sich um ein Verschleißteil, das während der Lebensdauer des Etikettendruckers unter Umständen ein- oder mehrfach ausgetauscht werden muss. Der Austausch der Druckwalze ist jedoch aufwändig und kann oft nur durch einen Service-Techniker vorgenommen werden.The platen roller is a consumable part that may need to be replaced one or more times during the life of the label printer. However, replacing the print roller is time-consuming and can often only be carried out by a service technician.
Der Erfindung liegt die Aufgabe zugrunde, einen Etikettendrucker der eingangs genannten Art anzugeben, der einen einfachen Austausch der Druckwalze ermöglicht.The invention is based on the object of specifying a label printer of the type mentioned at the outset, which enables the print roller to be replaced in a simple manner.
Diese Aufgabe wird durch einen Etikettendrucker mit den Merkmalen des unabhängigen Anspruchs 1 gelöst, und insbesondere dadurch, dass die Druckwalze in eine Druckwalzenaufnahme des Etikettendruckers eingesetzt ist und durch das Abstreifelement verliersicher in der Druckwalzenaufnahme gehalten ist.This object is achieved by a label printer having the features of independent claim 1, and in particular in that the print roller is inserted into a print roller mount of the label printer and is captively held in the print roll mount by the stripping element.
Erfindungsgemäß ist die Druckwalze also nicht kompliziert in dem Etikettendrucker verbaut, sondern es ist lediglich erforderlich, die Druckwalze in eine Druckwalzenaufnahme einzusetzen und durch das ohnehin vorhandene Abstreifelement dann in der eingesetzten Position verliersicher zu halten. Der Austausch der Druckwalze kann dann auch durch einen ungeschulten Bediener erfolgen.According to the invention, the print roller is not installed in a complicated manner in the label printer, but it is only necessary to insert the print roller into a print roller receptacle and then to keep it captive in the inserted position by the stripping element that is present anyway. The pressure roller can then also be replaced by an untrained operator.
Nach einer bevorzugten Ausbildung der Erfindung umfasst der Etikettendrucker einen dem Abstreifelement in Transportrichtung der Endlosband-Etiketten nachgeschalteten Abschneider zum Vereinzeln der Endlosband-Etiketten, der eine Transportrolle und eine parallel zu der Drehachse der Transportrolle linear verfahrbare Messereinheit umfasst, wobei die Endlosband-Etiketten zwischen der Transportrolle und der Messereinheit hindurchführbar sind, und wobei die Transportrolle des Abschneiders an dem Abstreifelement gelagert ist. Die Transportrolle dient dabei als Gegenhalter für ein Schneidmesser der Messereinheit. Durch die Lagerung der Transportrolle des Abschneiders direkt an dem Abstreifelement kann eine kompakte Ausbildung erreicht werden. Insbesondere kann der Abstand zwischen der Druckwalze und der Transportrolle des Abschneiders gering gehalten werden, so dass ein etwaiges Reversieren der Endlosband-Etiketten auf ein Minimum begrenzt, unter Umständen vollständig vermieden, werden kann, wodurch die Druckgeschwindigkeit des Etikettendruckers erhöht werden kann.According to a preferred embodiment of the invention, the label printer comprises a cutter downstream of the stripping element in the transport direction of the endless strip labels for separating the endless strip labels, which cutter comprises a transport roller and a knife unit that can be moved linearly parallel to the axis of rotation of the transport roller, with the endless strip labels between the Transport roller and the knife unit can be passed through, and wherein the transport roller of the cutter is mounted on the stripping element. The transport roller serves as a counter-holder for a cutting knife of the knife unit. By mounting the transport roller of the cutter directly on the stripping element a compact training can be achieved. In particular, the distance between the pressure roller and the transport roller of the cutter can be kept small, so that any reversing of the endless tape labels can be limited to a minimum, or even completely avoided, whereby the printing speed of the label printer can be increased.
Zur Lagerung des Abschneiders an dem Abstreifelement kann das Abstreifelement einen langgestreckten Abstreifabschnitt umfassen, dessen Längserstreckung parallel zu der Drehachse der Druckwalze verläuft und der an seinen beiden in Richtung der Drehachse der Druckwalze liegenden Enden einen jeweiligen Aufnahmeabschnitt, insbesondere mit einer jeweiligen randseitigen Ausnehmung, für die beiden axialen Enden der Transportrolle des Abschneiders aufweist. Die Transportrolle kann dann einfach in die beiden Aufnahmeabschnitte, insbesondere die beiden randseitigen Ausnehmungen, eingesetzt werden.To mount the cutter on the stripping element, the stripping element can comprise an elongated stripping section, the longitudinal extent of which runs parallel to the axis of rotation of the pressure roller and which, at its two ends lying in the direction of the axis of rotation of the pressure roller, has a respective receiving section, in particular with a respective peripheral recess, for the both axial ends of the transport roller of the cutter. The transport roller can then simply be inserted into the two receiving sections, in particular the two recesses on the edge.
Dabei kann vorgesehen sein, dass das jeweilige axiale Ende der Transportrolle durch eine jeweilige axial eingesetzte Lagerhülse in der jeweiligen Ausnehmung des jeweiligen Aufnahmeabschnitts des Abstreifelements gesichert ist. Alternativ kann auch vorgesehen sein, dass das jeweilige axiale Ende der Transportrolle unter Ausbildung einer jeweiligen Schnappverbindung in die jeweilige Ausnehmung des jeweiligen Aufnahmeabschnitts des Abstreifelements eingesetzt ist. In beiden Fällen kann die Transportrolle auf besonders einfache Weise an dem Abstreifelement gelagert werden.It can be provided that the respective axial end of the transport roller is secured by a respective axially inserted bearing sleeve in the respective recess of the respective receiving section of the stripping element. Alternatively, it can also be provided that the respective axial end of the transport roller is inserted into the respective recess of the respective receiving section of the stripping element, forming a respective snap connection. In both cases, the transport roller can be mounted on the stripping element in a particularly simple manner.
Nach einer bevorzugten Ausbildung der Erfindung umfasst der Etikettendrucker einen Gehäusekasten und ein an einer offenen Seite des Gehäusekastens angebrachtes, zwischen einer Geschlossen-Stellung und einer Offen-Stellung um eine Schwenkachse klappbares Gehäuseelement, insbesondere eine Tür, wobei der Druckkopf, und insbesondere die vorgenannte Messereinheit, in dem Gehäusekasten angebracht ist, insbesondere sind, und die Druckwalze und das Abstreifelement, und insbesondere die vorgenannte Transportrolle, an dem klappbaren Gehäuseelement angebracht sind. In der Offen-Stellung ist die Druckwalze mit dem klappbaren Gehäuseelement aus dem Gehäusekasten herausgeschwenkt und damit für einen Austausch besonders gut zugänglich.According to a preferred embodiment of the invention, the label printer comprises a housing and a housing element attached to an open side of the housing and which can be folded between a closed position and an open position about a pivot axis, in particular a door, with the print head and in particular the aforementioned blade unit , mounted in the housing box, in particular, and the pressure roller and the scraper element, and in particular the aforesaid transport roller, are attached to the foldable housing element. In the open position, the pressure roller with the hinged housing element is pivoted out of the housing box and is therefore particularly easily accessible for replacement.
Insbesondere kann die Druckwalze in der Geschlossen-Stellung des klappbaren Gehäuseelements durch eine in dem Gehäusekasten angeordnete Sicherungseinrichtung fest in dem Etikettendrucker fixiert werden, die beim Schließen des klappbaren Gehäuseelements wirksam wird. Dies ist insbesondere dann vorteilhaft, wenn die verliersichere Halterung der Druckwalze in der Druckwalzenaufnahme durch das Abstreifelement spielbehaftet ist.In particular, when the hinged housing element is in the closed position, the printing roller can be firmly fixed in the label printer by a safety device which is arranged in the housing box and becomes effective when the hinged housing element is closed. This is particularly advantageous when the captive mounting of the pressure roller in the pressure roller receptacle is subject to play due to the stripping element.
Insbesondere kann das klappbare Gehäuseelement zwei einander gegenüberliegende, mit ihrem jeweiligen ersten Ende an einer jeweiligen Seitenwand des Gehäuses angelenkte Seitenwangen umfassen, die sich in der Geschlossen-Stellung des klappbaren Gehäuseelements in den Gehäusekasten hinein erstrecken und an denen, insbesondere an ihrem jeweiligen zweiten Ende, die Druckwalzenaufnahme, insbesondere in Form einer jeweiligen randseitigen Ausnehmung für die beiden axialen Enden der Druckwalze ausgebildet ist. Hierdurch kann eine einfache und stabile Lagerung der Druckwalze erreicht werden. Insbesondere kann die Druckwalze einfach in die beiden randseitigen Ausnehmungen eingesetzt werden. Die vorgenannte Sicherungseinrichtung kann in diesem Fall beispielsweise zwei Anschläge umfassen, die am Ende des Schließens des klappbaren Gehäuseelements gegen die beiden axialen Enden der in den Gehäusekasten einschwenkenden Druckwalze drücken.In particular, the foldable housing element can comprise two opposite side walls, which are articulated with their respective first end to a respective side wall of the housing, which extend into the housing box in the closed position of the foldable housing element and on which, in particular at their respective second end, the pressure roller receptacle, in particular in the form of a respective marginal recess for the two axial ends of the pressure roller. In this way, a simple and stable mounting of the pressure roller can be achieved. In particular, the pressure roller can be easily inserted into the two edge recesses. In this case, the aforementioned safety device can comprise, for example, two stops which, at the end of the closing of the foldable housing element, press against the two axial ends of the pressure roller pivoting into the housing box.
Vorzugsweise ist die Druckwalze mittelbar über ein Lagerelement, insbesondere eine Lagerhülse, an jedem ihrer beiden axialen Enden in der Druckwalzenaufnahme gelagert. Durch die beiden Lagerelemente kann die Lagerfläche für die beiden axialen Enden der Druckwalze erhöht werden. Ferner kann die technische Flexibilität bei der Lagerung der Druckwalze erhöht werden. Beispielsweise kann das jeweilige Lagerelement mit einer Federkraft beaufschlagt werden, z.B. wie es nachfolgend erläutert ist, ohne dabei die Drehbewegung der Druckwalze zu beeinflussen.The pressure roller is preferably mounted indirectly via a bearing element, in particular a bearing sleeve, at each of its two axial ends in the pressure roller receptacle. The bearing surface for the two axial ends of the pressure roller can be increased by the two bearing elements. Furthermore, the technical Flexibility in the storage of the pressure roller can be increased. For example, the respective bearing element can be subjected to a spring force, for example as explained below, without influencing the rotational movement of the pressure roller.
Die beiden Seitenwangen können über eine Querstrebe miteinander verbunden sein. Dabei ist es bevorzugt, wenn das Abstreifelement an der Querstrebe des klappbaren Gehäuseelements angebracht ist. Hierdurch wird eine besonders einfache und gleichzeitig besonders stabile Konstruktion erreicht.The two side walls can be connected to one another via a cross brace. In this case, it is preferred if the stripping element is attached to the cross brace of the foldable housing element. As a result, a particularly simple and at the same time particularly stable construction is achieved.
Insbesondere kann die Druckwalze unter einem Winkel im Bereich von 60° bis 120° zu der Etikettenbahn aus der Druckwalzenaufnahme entnehmbar und in die Druckwalzenaufnahme einsetzbar sein. In diesem Winkelbereich kann die verliersichere Halterung der Druckwalze in der Druckwalzenaufnahme durch das Abstreifelement besonders einfach realisiert werden.In particular, the pressure roller can be removed from the pressure roller seat and inserted into the pressure roller seat at an angle in the range of 60° to 120° to the label web. In this angular range, the captive holding of the pressure roller in the pressure roller receptacle can be implemented particularly easily by the stripping element.
Das Abstreifelement und die Druckwalze können in einer Projektion auf die Etikettenbahn einen Überlapp im Bereich von 0,3 mm bis 3 mm, bevorzugt 0,3 mm bis 2 mm, aufweisen. Hierdurch kann die Abstreiffunktion des Abstreifelements auch bei dem vorgenannten Reversieren der Endlosband-Etiketten jederzeit gewährleistet werden. Der direkte bzw. näheste Abstand zwischen dem Abstreifelement und der Druckwalze kann beispielsweise im Bereich von 0,5 mm bis 3 mm liegen. Der Durchmesser der Druckwalze kann einen Wert beispielsweise im Bereich von 10 mm bis 35 mm betragen.The stripping element and the pressure roller can have an overlap in the range of 0.3 mm to 3 mm, preferably 0.3 mm to 2 mm, in a projection onto the label web. As a result, the stripping function of the stripping element can be guaranteed at all times, even during the aforementioned reversing of the endless strip labels. The direct or closest distance between the stripping element and the pressure roller can be in the range of 0.5 mm to 3 mm, for example. The diameter of the pressure roller can have a value in the range from 10 mm to 35 mm, for example.
Gemäß einer Ausführungsform der Erfindung ist die Druckwalze aus einem elastisch verformbaren Material, insbesondere Silikon, gefertigt und, bei entsprechend großer Krafteinwirkung, unter Ausbildung einer elastischen Verformung zerstörungsfrei an dem Abstreifelement vorbei aus der Druckwalzenaufnahme herauszwängbar und in die Druckwalzenaufnahme hineinzwängbar. Der hierfür erforderliche Kraftaufwand kann über den vorgenannten Überlapp eingestellt werden. Diese Konstruktion ist besonders kostengünstig. Es sind keine weiteren Haltemittel erforderlich, um die Druckwalze in der Druckwalzenaufnahme zu halten.According to one embodiment of the invention, the pressure roller is made of an elastically deformable material, in particular silicone, and, with the application of a correspondingly large force, can be forced out of the pressure roller receptacle and into the pressure roller receptacle non-destructively, with the formation of an elastic deformation past the stripping element. The one required for this Effort can be adjusted via the aforementioned overlap. This construction is particularly inexpensive. No further holding means are required to hold the printing roller in the printing roller mount.
Gemäß einer weiteren Ausführungsform der Erfindung ist die Druckwalze, insbesondere mittels einer Langlochanordnung und/oder quer zu einer Entnahmerichtung der Druckwalze, zwischen einer Betriebsposition, in der die Druckwalze durch das Abstreifelement verliersicher in der Druckwalzenaufnahme gehalten ist und in die die Druckwalze mittels einer Federeinrichtung vorgespannt ist, und einer Entnahmeposition, in der die Druckwalze ohne Widerstand durch das Abstreifelement aus der Druckwalzenaufnahme entnehmbar ist, verschiebbar gelagert. Bei dieser Konstruktion ist zur Überwindung der Vorspannung der Federeinrichtung, um die Druckwalze in die Entnahmeposition zu verschieben, lediglich ein geringer Kraftaufwand erforderlich.According to a further embodiment of the invention, the pressure roller, in particular by means of a slot arrangement and/or transversely to a removal direction of the pressure roller, is between an operating position in which the pressure roller is held captively in the pressure roller receptacle by the stripping element and in which the pressure roller is prestressed by means of a spring device is, and a removal position in which the pressure roller can be removed without resistance by the stripping element from the pressure roller holder, slidably mounted. With this construction, only a small amount of force is required to overcome the prestressing of the spring device in order to move the pressure roller into the removal position.
Gemäß einer anderen Ausführungsform der Erfindung ist das Abstreifelement lösbar in dem Etikettendrucker befestigt, wobei die Druckwalze nach Lösen, insbesondere Abschrauben, insbesondere mittels einer Rändelschraube, des Abstreifelements ohne Widerstand durch das Abstreifelement aus der Druckwalzenaufnahme entnehmbar ist. Diese Konstruktion ist für den Bediener zwar aufwändiger, aber intuitiv.According to another embodiment of the invention, the stripping element is releasably fastened in the label printer, the pressure roller being removable by the stripping element from the pressure roller receptacle without resistance after the stripping element has been loosened, in particular unscrewed, in particular by means of a knurled screw. Although this construction is more complex for the operator, it is intuitive.
Vorzugsweise ist die Druckwalze werkzeuglos aus der Druckwalzenaufnahme entnehmbar und in die Druckwalzenaufnahme einsetzbar, insbesondere wie es bei den vorstehenden Ausführungsformen beschrieben ist. Das Austauschen der Druckwalze kann damit besonders einfach und komfortabel erfolgen.The pressure roller can preferably be removed from the pressure roller receptacle and inserted into the pressure roller receptacle without tools, in particular as is described in the above embodiments. The replacement of the pressure roller can thus be carried out particularly easily and conveniently.

Der Etikettendrucker 19 weist einen Gehäusekasten 21 auf, der nach vorne offen ist, wobei diese offene Seite des Gehäusekastens 21 durch ein an dem Gehäusekasten 21 angebrachtes, um eine Schwenkachse D klappbares Gehäuseelement 23 verschließbar ist, wobei in
Die
Der Abschneider 31 umfasst gemäß
Der Etikettendrucker 19 ist dabei derart aufgebaut, dass der Druckkopf 41 und die Messereinheit 35 in dem Gehäusekasten 21 angebracht sind, und dass die Druckwalze 43 und die Transportrolle 33 an dem klappbaren Gehäuseelement 23 angebracht sind, wie insbesondere aus den
Die Rahmenkonstruktion 45 des klappbaren Gehäuseelements 23 umfasst gemäß
An ihren zweiten Enden weisen die beiden Seitenwangen 47 eine jeweilige randseitige Ausnehmung 53 auf, in die die beiden axialen Enden der Druckwalze 43 eingesetzt sind, wie insbesondere in
Darüber hinaus ist ein Abstreifelement 61 vorgesehen, das in Transportrichtung der Endlosband-Etiketten gesehen der Druckwalze 43 unmittelbar nachgeschaltet und dem Abschneider 31 unmittelbar vorgeschaltet ist, d.h. zwischen der Druckwalze 43 und der Transportrolle 33 des Abschneiders 31 angeordnet ist, wie insbesondere in den
Das Abstreifelement 61 ist ebenfalls an dem klappbaren Gehäuseelement 23 angebracht und wird beim Schließen des klappbaren Gehäuseelements 23 in den Gehäusekasten 21 hineingeschwenkt. Konkret ist das Abstreifelement 61 über zwei Schrauben 59 in Schließrichtung S des klappbaren Gehäuseelements 23 gesehen außen an der Querstrebe 51 der Rahmenkonstruktion 45 des klappbaren Gehäuseelements 23 angebracht (vgl. die
Das Abstreifelement 61 dient dabei auch als Halterung und Lagerung der Transportrolle 33 des Abschneiders 31 (vgl.
Darüber hinaus ist das Abstreifelement 61 derart nahe an der Druckwalze 43 angeordnet und ist die Entnahmerichtung der Druckwalze 43 aus der Druckwalzenaufnahme 55 derart orientiert, dass die Druckwalze 43 durch das Abstreifelement 61 verliersicher in der Druckwalzenaufnahme 55 gehalten ist. Hierbei sind viele geometrisch voneinander verschiedene Varianten denkbar. Beispielsweise und bevorzugt besitzt das Abstreifelement 61 - in einer Projektion auf die Etikettenbahn 73 gesehen - mit der Druckwalze 43 einen Überlapp d von 0,3 mm bis 3 mm (vgl.
Trotz der verliersicheren Halterung kann die Druckwalze 43 gleichwohl ohne weiteres aus der Druckwalzenaufnahme 55 entnommen und ausgetauscht werden. Hierzu ist die Druckwalze 43 aus einem elastisch verformbaren Material wie Silikon gefertigt und kann deshalb an dem Abstreifelement 61 vorbei aus der Druckwalzenaufnahme 55 herausgezwängt werden. Hierbei verformt sich die Druckwalze 43 elastisch und damit zerstörungsfrei. Analog kann die neue Druckwalze 43 in die Druckwalzenaufnahme 55 hineingezwängt werden. Der Austausch der Druckwalze 43 kann daher werkzeuglos erfolgen.Despite the captive mounting, the
Natürlich ist es auch möglich, dass zunächst das Abstreifelement 61 von der Querstrebe 51 abgeschraubt wird und anschließend die Druckwalze 43 - ohne noch von dem Abstreifelement 61 gehalten zu werden - aus der Druckwalzenaufnahme 55 entnommen wird.Of course, it is also possible for the stripping
