Embodiment Construction

[0031] figure 1 A side view of a device 1 for individually printing a surface 3 of a three-dimensional moving object 2 that is curved in any direction is shown. The object may preferably have a flat, relief-formed or only slightly curved surface, such as Figure 4 and Figure 5 Indicated by number 2. The object may alternatively be a sphere. figure 2 A top view of the same device 1 is shown. In both figures, parts corresponding to each other are provided with the same reference numerals.

[0032] The device 1 comprises a printing unit 4 . The printing unit is arranged stationary in the upper region of the device. The printing unit comprises an inkjet printing head 5 . The print head is received in an orientation unit 26 of the printing unit. The orientation unit is arranged in an opening of a horizontally arranged plate 35 of a frame 34 of the device 1 . The plate has a plurality of openings whereby a plurality of print heads can be arranged. The opening and the plu...

Abstract

The apparatus for printing the surface of an object according to the invention comprises: a stationary printing unit (4) for printing an object (2), wherein the printing unit comprises an inkjet printing head (5) and the printing head is positioned between the printing head A print (6) is produced on the surface (3) of the object in the active area (7); a moving holding unit (11) is used for receiving the object in a receiving area (12) and for receiving the object by receiving Rotary movement of the area to the active area of ​​the printing head and for the linear movement of the object in the active area of ​​the printing head during the generation of the print; and at least one control unit (13) for controlling the movement of the holding unit and the generation of the print ).

Description

technical field [0001] The invention relates to a device for printing the surface of an object and a method for printing an object by means of the device. [0002] The invention belongs to the technical field of inkjet printing of spatially extended three-dimensional objects or shapes or their surfaces. Background technique [0003] It is already known that such objects are printed on special devices, for example golf balls can be printed individually using inkjet in specially configured printing devices. Such a device is disclosed in JP 11320863A. A golf ball is a relatively small object, and therefore its manipulation is rarely problematic. For larger objects, such as footballs, the manipulation is more difficult. The width of a print head is then no longer sufficient, for example, to print half of a ball in one pass. Furthermore, based on the size and curvature of the sphere, the edge nozzles of the print head have too large a spacing to the surface of the sphere and ...
