Description
Die Erfindung betrifft einen elektrophotographischen Drucker, insbesondere einen Laser- oder LED-Drucker, für Metallfolien, insbesondere Aluminiumfolien für Blisterverpackungen, mit einem Bildträger zum Übertragen von Toner aus einem Tonerbehälter auf die Metallfolie, und einer ersten Ladeeinheit, welche im Bereich der dem Bildträger zugewandten Seite der Metallfolie angeordnet ist.The invention relates to an electrophotographic Printers, especially a laser or LED printer, for Metal foils, in particular aluminum foils for blister packs, with an image carrier for transferring toner from a toner container on the metal foil, and one first loading unit, which in the area of the image carrier facing Side of the metal foil is arranged.
Bei heute bekannten Laser-Druckern wird ein Laserstrahl entsprechend dem Druckbild über eine sogenannte Bildwalze geführt, welche sich an den betreffenden Stellen elektrostatisch verändert. Die Oberfläche der Bildwalze wird nach der Beschriftung durch den Laserstrahl an einer Toner-Einheit vorbeigeführt, wodurch sich die elektrostatisch veränderten Bereiche der Bildwalze mit Toner bedecken. Der an der Bildwalze haftende Toner wird nachfolgend an das zu bedruckende Medium abgegeben. Dies geschieht in der Weise, daß das zu bedruckende Medium ebenfalls entsprechend elektrostatisch aufgeladen ist, wodurch der an der Bildwalze haftende Toner auf das zu bedruckende Medium übertragen wird. Je nach Größe der elektrostatischen Aufladung des zu bedruckenden Mediums wird der Toner entweder vollständig oder nur teilweise von der Bildwalze abgegeben. Der an der Bildwalze verbleibende Toner wird mittels einer Reinigungseinheit von der Bildwalze entfernt und in einem Behälter für verbrauchten Toner gesammelt.In today's known laser printers, a laser beam is used accordingly guided the print image over a so-called image roller, which are electrostatic at the relevant points changed. The surface of the image roller is after the Labeling by the laser beam on a toner unit passed, causing the electrostatically changed Cover areas of the image roller with toner. The one on the image roller adhering toner is subsequently attached to the one to be printed Medium released. This happens in such a way that printing medium also electrostatically is charged, causing the toner adhering to the image roller is transferred to the medium to be printed. Depending on Size of the electrostatic charge to be printed Medium, the toner becomes either complete or only partial released by the image roller. The one remaining on the image roller Toner is removed by a cleaning unit from the image roller removed and in a container for used Toner collected.
Die elektrostatische Aufladung des zu bedruckenden Mediums geschieht regelmäßig durch eine Ladeeinheit, einer sogenannten Korona, welche an der der Bildwalze abgewandten Seite des zu bedruckenden Mediums angeordnet ist.The electrostatic charging of the medium to be printed happens regularly through a loading unit, a so-called Corona, which on the side facing away from the image roller of the medium to be printed is arranged.
Daraus ergibt sich der Nachteil, daß beispielsweise dickere Folien nicht so stark aufgeladen werden können, daß sie genügend Toner von der Bildwalze abnehmen können, wodurch das Druckbild zu schwach wird und eine größere Menge Toner auf der Bildwalze verbleibt. Der nicht abgezogene Toner ist verbraucht und muß entsorgt werden. Um das Druckbild stärker zu machen, muß mehr Toner auf die Bildwalze aufgebracht werden. Hierdurch wird zwar das Druckbild etwas stärker, jedoch erhöht sich auch die Menge des verbrauchten Toners. Dies wirkt sich nicht nur nachteilig auf die Kosten aus, sondern belastet darüber hinaus auch noch die Umwelt.This results in the disadvantage that, for example, thicker ones Foils cannot be charged so much that they are sufficient Can remove toner from the image roller, causing the Print image becomes too weak and a large amount of toner appears the image roller remains. The toner that has not been removed is used up and must be disposed of. To make the printed image stronger to make more toner must be applied to the image roller. This will make the printed image a little stronger, however the amount of toner consumed also increases. Not only does this have a negative impact on costs, but also pollutes the environment.
Der vorher beschriebene Nachteil tritt nicht nur bei dicken Folien, sondern auch besonders stark bei Metallfolien auf. Metallfolien können mit bisher bekannten elektrophotographischen Druckern nicht oder nur unzureichend bedruckt werden. Aus der US-A-5,172,174 ist ein Druckersystem bekannt, bei welcher Toner von einer Bildwalze auf eine Folie übertragen wird. Zur Übertragung des Toners auf die Folie ist eine erste Ladeeinheit vorgesehen, welche der Bildwalze gegenübersteht und an der Stelle angeordnet ist, an der die Bildwalze mit der Folie in Berührung kommt. Des weiteren ist im Bereich der dem Bildträger zugewandten Seite der Folie eine zweite Ladeeinheit angeordnet, mittels der die dem Bildträger zugewandte Seite der Folie so aufgeladen wird, daß eine Übertragung von Toner vom Bildträger auf die Folie verhindert wird.The previously described disadvantage does not only occur with thick ones Foils, but also particularly strongly with metal foils. Metal foils can be made using previously known electrophotographic Printers are not or only insufficiently printed. From US-A-5,172,174 a printer system is known in which Toner is transferred from an image roller to a film. A first loading unit is used to transfer the toner to the film provided which faces the image roller and on is located at the point where the image roller with the film comes into contact. Furthermore, in the field of Image carrier facing side of the film a second loading unit arranged by means of which the side of the image carrier facing the Foil is charged so that a transfer of toner from the Image carrier on the slide is prevented.
Des weiteren ist aus der EP-A-0 309 588 ein Druckersystem bekannt, bei dem Toner von einer Bildwalze auf eine Folie übertragen wird. Im der Folie abgewandten Bereich der Bildwalze ist eine Ladeeinheit angeordnet, mittels der die Oberfläche der Bildwalze aufgeladen wird, damit sie zur Aufnahme von Toner geeignet ist. Ebenfalls an der Stelle, an der die Bildwalze mit der Folie in Berührung kommt, ist an der der Bildwalze abgewandten Seite der Folie eine Transfereinheit angeordnet. Furthermore, a printer system is known from EP-A-0 309 588, transferring the toner from an image roller to a film becomes. In the area of the image roller facing away from the film a loading unit arranged by means of which the surface of the Image roller is charged so that it is suitable for the absorption of toner is. Also at the point where the image roller with the film comes into contact is on the side facing away from the image roller A transfer unit is arranged on the side of the film.
Es ist daher Aufgabe der Erfindung, einen eingangs genannten elektrophotographischen Drucker derart auszubilden, daß er zum Bedrucken von Metallfolien bei möglichst geringem Tonerverbrauch geeignet ist.It is therefore an object of the invention, one mentioned at the outset to train electrophotographic printers in such a way that he for printing metal foils with as little as possible Toner consumption is suitable.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des
kennzeichnenden Teils des Anspruchs 1. Vorteilhafte Weiterbildungen
der Erfindung ergeben sich aus den abhängigen Ansprüchen.The solution to this problem results from the features of
characterizing part of
Gemäß der Erfindung ist die Ladeeinheit an der der Bildwalze zugewandten Seite der Metallfolie angeordnet. Es hat sich gezeigt, daß durch eine derart angeordnete Ladeeinheit Metallfolien ohne eine größere Aufbringung von Toner auf den Bildträger mit sehr gutem Ergebnis bedruckt werden können. Durch die erfindungsgemäße Anordnung entspricht das auf eine Metallfolie aufgebrachte Druckbild etwa dem bei Zuführung einer gleichen Tonermenge auf den Bildträger dem auf eine Papierbahn mit einer herkömmlichen Anordnung der Ladeeinheit aufgebrachten Druckbild.According to the invention, the loading unit is on that of the image roller facing side of the metal foil arranged. It has it has been shown that such a loading unit arranged Metal foils without applying a large amount of toner the image carrier can be printed with very good results. This corresponds to the arrangement according to the invention printed image applied to a metal foil, for example that of Feeding an equal amount of toner onto the image carrier on a paper web with a conventional arrangement of Load unit applied print image.
Zum Bedrucken von stärkeren Folien kann im Drucker jedoch eine weitere Ladeeinheit vorgesehen sein, welche auf herkömmliche Weise an der dem Bildträger abgewandten Seite der Folie angeordnet ist. Bei einem derart ausgebildeten Drucker kann in vorteilhafter Weise eine Steuerung vorgesehen sein, mittels der die erste und die zweite Ladeeinheit aktiviert werden können. Bei Bedarf kann somit entweder die erste, die zweite oder beide Ladeeinheiten aktiviert werden. Die Steuerung kann jedoch auch so ausgebildet sein, daß die Höhe der an den Ladeeinheiten anliegenden Spannungen einstellbar ist. Hierdurch ergibt sich ein großer Bereich, innerhalb dessen ein zu bedruckendes Medium statisch aufgeladen werden kann. However, you can use the printer to print thicker films a further loading unit can be provided, which is based on conventional Way on the side facing away from the image carrier Foil is arranged. With such a trained A controller can advantageously be provided for the printer be, by means of which the first and the second loading unit can be activated. If necessary, either first, second or both loading units are activated. However, the control can also be designed that the level of the voltages applied to the loading units is adjustable. This creates a large area within which a medium to be printed is static can be charged.
Es können beispielsweise unterschiedlich dicke Folien bedruckt werden oder auch Folien aus einem Material, welches sich von unten schlecht statisch aufladen läßt. Selbstverständlich können mit einem erfindungsgemäßen Drucker auch nichtmetallische Folien bedruckt werden. Die erfindungsgemäße Anordnung erlaubt das Bedrucken von sehr dicken oder schwer aufladbaren Materialien.For example, films of different thicknesses can be printed or foils made of a material which is difficult to charge statically from below. Of course can also with a printer according to the invention non-metallic foils can be printed. The invention Arrangement allows printing of very thick or difficult to recharge materials.
Die Ladeeinheiten können in vorteilhafter Weise sich gegenüberstehend angeordnet sein. Sie könnten dann als eine Einheit ausgebildet sein. Dies wirkt sich vorteilhaft auf die Bauform und die Herstellungskosten aus.The loading units can advantageously face each other be arranged. You could then as a unit be trained. This has a beneficial effect on the Design and manufacturing costs.
Wenn es jedoch erforderlich ist, können die Ionisiereinheiten auch in Transportrichtung der Metallfolie versetzt angeordnet sein. So kann die erste Ladeeinheit im Bereich in Transportrichtung der Folie gesehen vor dem Bildträger angeordnet sein und die zweite Ladeeinheit unterhalb des Bildträgers.However, if necessary, the ionizing units can also offset in the transport direction of the metal foil his. The first loading unit in the area in Transport direction of the film seen in front of the image carrier be and the second loading unit below the image carrier.
Da durch die erfindungsgemäße Ausgestaltung eines elektrophotographischen Druckers Metallfolien ohne eine erhöhte Aufbringung von Toner auf den Bildträger bedruckt werden können, ergibt sich eine erhebliche Kostensenkung beim Drucken. Darüber hinaus fällt bedeutend weniger Toner-Abfall an, wodurch die Umwelt entlastet wird.Since the inventive design of an electrophotographic Printer's metal foils without an elevated Application of toner to be printed on the image carrier can result in a significant cost reduction in To press. In addition, there is significantly less waste of toner which relieves the burden on the environment.
Wenngleich die vorliegende Erfindung auch anhand eines Laser-Druckers beschrieben wurde, so kann sie selbstverständlich auch bei einem Drucker angewendet werden, bei welchem der Bildträger in anderer Weise beschrieben wird, und die Schwärzungsmittel wie Toner, Farbe usw. mittels Ladeeinheiten auf das zu bedruckende Medium übertragen werden, wie beispielsweise bei einem elektromagnetischen Drucker nach einem magnetischen Prinzip oder bei einem Ionen-Drucker nach einem Ionentransfer-Prinzip. Although the present invention is also based on a Laser printer has been described, so it can be taken for granted can also be applied to a printer at which the image carrier is described in another way, and the blackening agents such as toner, color, etc. by means of Transfer loading units to the medium to be printed like an electromagnetic one Printer based on a magnetic principle or at a Ion printer based on an ion transfer principle.
