Embodiment Construction

[0029] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Fig. 1 is a schematic perspective view of an apparatus 1 for on-the-job patterning as a preferred embodiment of the present invention. The device is used to produce a pattern on a workpiece 2 which, in the preferred embodiment, is at least partially composed of wood, wooden materials, plastic materials etc., such as are commonly used in the field of furniture and kitchen design.

[0031] The device 1 comprises an inkjet printing device 10 which in this embodiment operates according to the drop-on-demand principle. As most clearly seen in FIG. 4 , the inkjet printing device 10 includes a plurality of nozzles 12 from which ink droplets may be ejected, and in this embodiment, the nozzles are arranged in columns, each column arranged as For ejecting predetermined colors such as cyan, magenta, yellow, and black.

[0032] A drying unit 14, s...

Abstract

The invention provides a device for patterning workpieces, having: an ink-jet printing means having a plurality of nozzles from which drops of ink can be expelled, a workpiece carrier means for carrying the workpiece to be patterned, a conveyor means for bringing about a relative movement between the workpiece to be patterned and the printing means, and a detection means for detecting the relative position between the ink-jet printing means and at least one surface to be patterned of the respective workpiece to be patterned. The device according to the invention is characterised in that the detection means is disposed and configured so as to be in a predetermined, fixed relationship to the ink-jet printing means and / or to detect at least the distance between the ink-jet printing means and at least one surface to be patterned of the respective workpiece to be patterned, at least during printing.

Description

technical field [0001] The invention relates to a device for making a pattern on a workpiece according to the preamble of claim 1 , said workpiece preferably consisting at least partially of wood, wooden material or the like. Background technique [0002] A device of the above-mentioned type is known, for example, from DE 100 31 030 B4, which has a sensor for roughly detecting the contour and thickness of a workpiece to be printed attached to a transfer device or a portal. However, it has been found that the quality of the printed image of workpieces printed with such equipment is generally poor. [0003] Furthermore, the not yet published European patent application EP 05 009326.9 filed by the applicant also relates to a device according to the preamble of claim 1 . Contents of the invention [0004] It is therefore an object of the present invention to provide a device of the same type for making patterns on workpieces which results in an improved quality of the printed...
