Abstract

Three dimensional objects are printed with patterns or symbols using an ink jet plotter. The pattern information is obtained by scanning and is then down loaded to the plotter. Different inks may be used to suit the materials of the objects and the movement between plotter and object surface held constant.

Description

Das Verfahren zur Beschriftung gebogener Materialien oder Werkstücke wird dadurch gekennzeichnet, daß durch Laser- und/ oder -Walzenabtastung ein Tintenstrahl über ein gebogenes Werkstück geführt wird. Vorgegebene Grafiken und Schriftzüge werden über Computer gelesen und dem Tintenstrahldrucker zugeführt.The procedure for labeling curved materials or workpieces is characterized, that by laser and / or roller scanning an ink jet over a curved Workpiece is guided. Specified graphics and lettering are read on the computer and the Inkjet printer supplied.

AusführungenExecutions

Unser Bestreben ist es, gebogene Werkstücke (z. B. Stuhllehnen) durch einen Tintenstrahldrucker zu beschriften. Dieser Tintenstrahldrucker paßt sich durch Laser- und/oder Walzenabtastung dem Werkstück an. Um einen zufriedenstellenden Druck (scharfes Bild) zu erhalten, werden die Werkstücke entsprechend vorbehandelt (schleifen usw.).Our aim is to have bent workpieces (e.g. chair backs) by one Label inkjet printer. This inkjet printer fits through Laser and / or roller scanning on the workpiece. To get a satisfactory print (sharp image), the Workpieces pre-treated accordingly (grinding, etc.).

Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, daß Werkstücke (z. B. Stuhllehnen aus Holz) selten millimetergenau gebogen sind. Schwankungen von 0,1 cm-2 cm sind keine Seltenheit. Dieses Problem wird durch Laser- und/ oder Walzenabtastung aufgehoben. Durch die genaue Abtastung ist neben der Beschriftung von ein- oder zweidimensionalen Werkstücken auch die Bearbeitung von dreidimensionalen Teilen möglich.The invention specified in the claim is based on the problem that Workpieces (e.g. wooden armrests) are rarely bent to the millimeter. Fluctuations of 0.1 cm-2 cm are not uncommon. This problem is overcome by laser and / or roller scanning. By the exact scanning is in addition to the labeling of one- or two-dimensional Workpieces can also process three-dimensional parts.

Um verschiedenste Materialien ihren Eigenschaften entsprechend zu beschriften, ist es lediglich nötig, einen Farb- bzw. Patronenwechsel vorzunehmen. In order to label various materials according to their properties, it is only necessary to change the color or cartridge.  

Die mit der ausgeführten Erfindung zu erzielenden Vorteile bestehen insbesondere darin:
The advantages to be achieved with the implemented invention are in particular:

  • - keine Lagerung von Druckvorlagen wie z. B. beim Walzendruck- No storage of print templates such. B. in roller printing
  • - wenig Abfall (Gegenbeispiel: Aufkleber)- little waste (counter example: sticker)
  • - extrem niedrige Rüstzeiten- extremely short set-up times
  • - schnelle und variable Anwendung (z. B. verschiedene Grafiken auf Ein-, Zwei- oder Dreiachsigen Werkstücken)- Fast and variable application (e.g. different graphics on one, two or Triaxial workpieces)
  • - kurze Trockenzeiten- short drying times
  • - durch sparsamen Einsatz von biologischen Farben ( z. B. Kunstharz) ist die Farbgebung sehr umweltfreundlich- through economical use of biological colors (e.g. synthetic resin) Coloring very environmentally friendly
  • - kein Abrieb der Grafiken, da diese in einem zweiten Arbeitsgang überlackiert werden.- No abrasion of the graphics, as these are overpainted in a second step become.

Durch dieses Beschriftungsverfahren ist eine rationelle, wirtschaftliche und zugleich umweltfreundliche Farbgebung auf gebogenen Werkstücken möglich.This labeling process is a rational, economical and at the same time environmentally friendly coloring on curved workpieces possible.

Claims (1)

Dreidimensional geformte Werkstücke (z. B. dickbauchige Flaschen, gebogene Stuhllehnen, KFZ-Ersatzteile usw.) werden nach Laser- und/oder Walzenabtastung bedruckt.
Das Bedrucken erfolgt in folgenden Schritten:
  • 1. Mittels eines Scanners werden vorgegebene Grafiken und Schriftzüge über Computer gelesen und dem Tintenstrahldrucker zugeführt.
  • 2. Die in Punkt 1. gespeicherten Daten werden mittels eines Tintenstrahldruckers auf das zu bearbeitende, 3-Dimensional geformte, Werkstück aufgebracht,
dadurch gekennzeichnet, daß:
dreidimensional geformte Werkstücke nach unmittelbar vorheriger Abtastung durch Walzen und/oder Laser an den Tintenstrahl herangeführt werden.
Abweichend vom bisherigen Stand der Technik ist hierbei:
Bei den bisherigen Verfahren ist es nur möglich, mit einem Tintenstrahldrucker in Ein- oder Zweidimensionalen Ebenen zu bedrucken.
Bei unserem Verfahren ermöglichen ein Scanner, ein Abtastimpuls und ein hierfür entwickelter Tintenstrahldrucker, auch das Bedrucken von dreidimensional geformten Werkstücken.Three-dimensionally shaped workpieces (e.g. thick-bellied bottles, curved armrests, vehicle spare parts, etc.) are printed after laser and / or roller scanning.
Printing takes place in the following steps:
  • 1. Using a scanner, predefined graphics and lettering are read on a computer and fed to the inkjet printer.
  • 2. The data stored in point 1. are applied to the 3-dimensionally shaped workpiece to be processed using an inkjet printer,
characterized in that:
three-dimensionally shaped workpieces are brought up to the ink jet after being scanned by rollers and / or lasers.
Deviating from the previous state of the art is:
With the previous methods, it is only possible to print in one or two dimensions with an inkjet printer.
With our process, a scanner, a scanning pulse and an inkjet printer developed for this purpose also enable the printing of three-dimensionally shaped workpieces.
