Embodiment Construction

[0028] figure 1 A side view of a preferred embodiment of the device 1 according to the invention for the individual printing of surfaces 3 curved in any direction of a three-dimensional moving object 2 is shown. The object may for example be a ball. figure 2 A plan view of the same preferred embodiment of the device 1 according to the invention is shown. Mutually corresponding elements are provided with the same reference numerals in both figures.

[0029] The device 1 comprises a printing unit 4 . The printing unit is arranged stationary in the upper region of the device. The printing unit includes 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 the frame 34 of the device 1 . The plate has multiple openings, so multiple print head arrangements are possible. The openings and the plurality of print heads are located on a circle 14 ...

Abstract

An apparatus for printing a curved surface of an object, for example a ball includes a stationary printing unit for printing the object, the printing unit including an inkjet print head producing a print on the object surface in an active region of the print head, a curing unit for curing the print, the curing unit including a radiant heater curing the print in an active region of the radiant heater, a movable holding unit for receiving the object in a receiving region, moving the object from the receiving region into the active region of the print head, moving the object in the active region of the print head during production of the print and moving the object into the active region of the curing unit, and a control unit for controlling the movements of the holding unit, the production of the print and the curing of the print.

Description

technical field [0001] The invention relates to a device having the features stated in the preamble of claim 1 . [0002] The invention is in the technical field of inkjet printing of spatially extended three-dimensional objects or objects or their surfaces. Background technique [0003] It is already known to print such objects in specific devices, for example golf balls can be printed individually with inkjet printing in specially designed printing devices. One such device is disclosed in document JP 11320863A. Golf balls are relatively small objects and therefore their handling is rarely problematic. In the case of larger objects, such as footballs, this processing becomes difficult. The width of the print head is then no longer sufficient, for example, to print half of the ball in one go. The result is that, due to the size and curvature of the ball, the edge nozzles of the print head have an excessively large distance from the ball surface and thus print inaccuratel...
