oder -Plotteror plotter
Inkjet-Printer oder -Plotter haben einen in einem Gehäuse horizontal verfahrbaren Druckkopf mit Inkjet-Düsen. Der Tintenvorrat ist durch einen mitfahrenden, mit Tinte getränkten Schaumkörper gebildet.Inkjet printers or plotters have a print head with inkjet nozzles that can be moved horizontally in a housing. The ink supply is formed by a moving foam body soaked in ink.

Fig. 4 eine zweite Ausführungsforra des Vorratsbehälters.Fig. 4 shows a second embodiment of the storage container.
Der Printer nach Fig. 1 hat ein Gehäuse 1, in welchem ein Schlitten 2 horizontal verfahrbar ist. Der Schlitten 2 trägt einen Druckkopf 3. Der Druckkopf 3 hat mehrere Inkjet-Düsen 4 und einen Tintenvorrat, z.B. in Form eines mit Tinte getränkten Schaumkörpers 5. Neben dem Gehäuse 1 ist ein Vorratsbehälter 10 mit freier Tinte 11 (Fig. 3) mit einer freien Oberfläche 12 angeordnet. Der Behälter 10 ist in einer Wanne 13 vertikal beweglich geführt und auf Federn 14 abgestützt. Die Federkonstante dieser Federn 14 ist derart bemessen, dass die Oberfläche 12 unabhängig vom Tinten-Vorratsvolumen auf annähernd gleichem Niveau bleibt. Dieses Niveau ist etwas tiefer als das Niveau der Düsen 4, so dass im Druckkopf 3 ein geringfügiger Unterdruck gebildet wird.The printer according to Fig. 1 has a housing 1 in which a carriage 2 can be moved horizontally. The carriage 2 carries a print head 3. The print head 3 has several inkjet nozzles 4 and an ink supply, e.g. in the form of a foam body 5 soaked in ink. A storage container 10 with free ink 11 (Fig. 3) with a free surface 12 is arranged next to the housing 1. The container 10 is guided vertically in a trough 13 and supported on springs 14. The spring constant of these springs 14 is dimensioned such that the surface 12 remains at approximately the same level regardless of the ink supply volume. This level is slightly lower than the level of the nozzles 4, so that a slight negative pressure is formed in the print head 3.
Der Vorratsbehälter 10 ist mit dem Druckkopf 3 über eine Verbindungsleitung 20 verbunden. Diese besteht aus einem in die Tinte 11 eingetauchten Röhrchen 21, einer in den Schaumkörper 5 eingesteckten Hohlnadel 22 und einem dasThe reservoir 10 is connected to the print head 3 via a connecting line 20. This consists of a tube 21 immersed in the ink 11, a hollow needle 22 inserted into the foam body 5 and a
Röhrchen 21 und die Nadel 22 verbindenden, flexiblen Verbindungsschlauch 23.Flexible connecting tube 21 and needle 22 23.
Um bei Inbetriebnahme die Leitung 20 mit der Tinte zu füllen ist auf dem Behälterdeckel 15 ein Pumpmittel angeordnet. Dieses ist in Fig. 3 als Luftpumpe 26 angedeutet. Die vereinfacht dargestellte Pumpe 26 besteht aus einer aufgewölbtea Gummimembran 27, die in der Mitte ein Loch 28 hat und am Rand auf dem Behälterdeckel 15 befestigt ist. Unterhalb der Membran 27 hat der Deckel 15 eine Oeffnung 29, die innen durch einen abhebbaren, flexiblen Folienlappen 30 verschlossen ist. Dieser bildet ein Rückschlagventil. Mit dieser Pumpe 26 kann manuell durch mehrmaliges Eindrücken der Membran 27 etwas Ueberdruck im Luftraum oberhalb der Tintenoberfläche 12 erzeugt werden. Damit wird die Tinte 11 in die Verbindungsleitung 20 getrieben. Sobald diese gefüllt ist, d.h. wenn etwas Tinte aus den Düsen 4 austritt, wird der Luftraum oberhalb der Oberfläche 12 wieder mit Atmosphärendruck beaufschlagt. Dazu kann z.B. ein Gummipfropfen 35 aus einer Oeffnung 36 des Deckels 15 oberhalb der Oberfläche 12 ausgezogen werden. Die Belüftungsöffnung kann auch in der Pumpe 2 6 integriert sein.In order to fill the line 20 with ink during operation, a pumping means is arranged on the container lid 15. This is indicated in Fig. 3 as an air pump 26. The simplified pump 26 consists of a curved rubber membrane 27, which has a hole 28 in the middle and is attached to the edge of the container lid 15. Below the membrane 27, the lid 15 has an opening 29, which is closed on the inside by a removable, flexible foil flap 30. This forms a check valve. With this pump 26, some excess pressure can be generated manually in the air space above the ink surface 12 by repeatedly pressing the membrane 27. This drives the ink 11 into the connecting line 20. As soon as this is filled, i.e. when some ink comes out of the nozzles 4, the air space above the surface 12 is again subjected to atmospheric pressure. For this purpose, for example, a rubber plug 35 can be pulled out of an opening 36 in the cover 15 above the surface 12. The ventilation opening can also be integrated into the pump 2 6.
Der erfindungsgemässe Tintenvorrat ermöglicht einen langen, ununterbrochenen Betrieb des Druckkopfs 3, ohne dass er ausgewechselt werden muss. Ein Plotter zum Herstellen von Zeichnungen kann z.B. über Nacht ohne Aufsicht betriebenThe ink supply according to the invention enables long, uninterrupted operation of the print head 3 without having to be replaced. A plotter for producing drawings can, for example, be operated overnight without supervision.
werden, was bei den heutigen Inkjet-Plottern wegen des beschränkten Tintenvorrats im Druckkopf 3 nicht möglich ist.which is not possible with today's inkjet plotters due to the limited ink supply in the print head 3.
In Fig. 4 ist eine zweite Ausführungsform des Vorratsbehälters 10 dargestellt. Dieser besteht hier aus einem luftdicht verschweissten, mit Tinte gefüllten Beutel 40. Am einen Rand 41 des Beutels 40 ist ein Gummipfropfen 42 eingesetzt, durch welchen eine weitere Hohlnadel 43 gesteckt ist. Diese bildet hier das zweite Ende der Verbindungsleitung 20. Der Beutelinnenraum ist luftfrei. Bei der Ausführungsform nach Fig. 4 braucht zum Auffüllen der Verbindungsleitung 20 und des Schaumkörpers 5 des Druckkopfes 3 bloss leicht auf den Beutel 40 gedrückt zu werden. Wenn der Beutel 40 flach ist, ändert sein Innendruck während des Verbrauches des Tintenvorrats nur wenig.Fig. 4 shows a second embodiment of the storage container 10. This consists of an airtight welded bag 40 filled with ink. A rubber stopper 42 is inserted into one edge 41 of the bag 40, through which another hollow needle 43 is inserted. This forms the second end of the connecting line 20. The interior of the bag is free of air. In the embodiment according to Fig. 4, the bag 40 only needs to be pressed lightly to fill the connecting line 20 and the foam body 5 of the print head 3. If the bag 40 is flat, its internal pressure changes only slightly as the ink supply is used up.
Die beschriebenen Zufuhrvorrichtungen eignen sich auch für Druckköpfe 3, die keinen Schaumkörper, sondern einen mit Tinte gefüllten Hohlraum enthalten.The described feed devices are also suitable for print heads 3 that do not contain a foam body but a cavity filled with ink.
