Assembly of at least one revolution object and one ink jet printing machine
First Claim
1. An assembly of at least one object having an outer surface of revolution around an axis of revolution and a machine for printing the object, the machine comprising:
- at least four printing stations, each printing station including at least two inkjet printheads, each printhead defining a median plane, the median planes intersecting the outer surface along two impact axes, respectively, seen from an opening angle from the axis of revolution;
a conveying system including at least one object carrier suitable for carrying the object, the conveying system being suitable for moving the object carrier relative to the printing stations sequentially in at least four printing positions in which the object is respectively across from one of the printing stations, the object carrier being suitable for rotating the object relative to the printing station around the axis of revolution in each of the printing positions, anda controller for controlling the conveying system and the printing stations, wherein, in each of the printing positions;
the two printheads of the printing station situated across from the object are offset relative to one another along the axis of revolution,the controller is configured so that said two printheads print the object during at least one printing period, andthe median planes form an angle strictly smaller than the opening angle.

Abstract
An assembly (1) of at least one object (5) having an outer surface (12) substantially of revolution around an axis of revolution (Δ) and a machine (10) for printing the object, the machine including: at least four printing stations (16, 18, 20, 22) including at least two inkjet printheads, each printhead defining a median plane, the median planes intercepting the outer surface along two impact axes, respectively, seen from an opening angle from the axis of revolution; a conveying system (35) including at least one object carrier (40) and suitable for moving the object carrier relative to the printing stations sequentially in at least four printing positions, the object carrier being suitable for rotating the object around the axis of revolution; and a controller. In each of the printing positions: the two printheads are offset relative to one another along the axis of revolution; the control system is configured so that said two printheads print the object during at least one printing period; and the median planes form an angle strictly smaller than the opening angle between them.

19. A method for printing at least one object having an outer surface of revolution around an axis of revolution, the method comprising the following steps:
-
providing a machine comprising at least four printing stations, a conveyor including at least one object carrier suitable for carrying the object, and a controller for controlling the conveyor and the printing stations, each printing station including at least two inkjet printheads, the two printheads being offset relative to one another along the axis of revolution, each printhead defining a median plane, the median planes intercepting the outer surface along two impact axes, respectively, seen from an opening angle from the axis of revolution, and the median planes forming an angle strictly smaller than or equal to the opening angle between them; moving the object carrier relative to the printing stations sequentially in at least four printing positions in which the object is respectively across from the printing stations; rotating the object relative to said printing station around the axis of revolution via the object carrier in each of the printing positions, and configuring the controller so that, in each printing position, the two printheads of the printing station situated across from the object print the object during at least the printing period.
