Definitions

  • the invention also relates to an assembly of such a printing machine and such a plurality of objects.
  • the invention finally relates to a corresponding method.
  • An ink jet printhead comprises on its underside rows of nozzles.
  • the spacing between each nozzle is equal to the definition, in dots per inch (DPI or dot per inch ).
  • the lower face comprises for example four rows of ninety nozzles each.
  • the two outermost rows are for example spaced 2.82 mm, while the nozzles, in the four rows, are spaced apart from each other by 0.0705 mm, which leads to a definition of 360 DPI.
  • the length of a row of nozzles is for example about 72 mm and the width of the lower face is for example 17.2 mm.
  • the width of the underside is the thickness of the print head.
  • the alignment direction of the ink jets extends in the direction of the length of the underside.
  • the document US-A-3,521,296 discloses a machine having a main frame on which is fixed a second frame having means for moving the object to be printed.
  • This second frame is pivotable relative to the main frame. In this way, by tilting the second frame relative to the main frame, it is possible to tilt the axis of revolution of the conical objects relative to the horizontal.
  • the objects are therefore all inclined under the different printing stations and have an upper generatrix in a horizontal plane corresponding to the different planes of the printing screens.
  • An object of the invention is therefore to overcome all or part of the above disadvantage, by providing a printing machine facilitating printing, especially on objects having an outer surface at least partly of revolution, in particular frustoconical or cylindrical.
  • the invention relates to a printing machine according to claim 1.
  • the printing machine comprises one or more of the features corresponding to claims 2 to 8, taken alone or in any technically possible combination.
  • the subject of the invention is also an assembly according to claim 9.
  • the invention also relates to a printing method according to claim 10.
  • the assembly 1 comprises a plurality of objects 5 to be printed, and a printing machine 6 for printing the objects.
  • Each object 5 has an outer surface 7, for example substantially of revolution about an object axis ⁇ ( figures 2 and 3 ).
  • Each object 5 is for example a bottle or a cup.
  • the outer surface 7 is for example frustoconical.
  • the outer surface 7 forms an angle ⁇ with the object axis ⁇ which defines the conicity of the objects 5.
  • the angle ⁇ is for example non-zero and less than or equal to 8.5 °.
  • the outer surface 7 is cylindrical.
  • the angle ⁇ is then substantially zero.
  • the object 5 does not have an outer surface completely of revolution.
  • the object 5 has a handle (not shown).
  • the object 5 is an object, for example flat, having at least one plane face to be printed.
  • the printing machine 6 comprises a frame 9, a turret support 11 adjustable in inclination around a pivot axis ⁇ 1 with respect to the frame, and a turret 13 rotatably mounted and indexed with respect to the frame around an axis of rotation. rotation ⁇ 2.
  • the printing machine 6 also comprises two processing stations 15, 17, and a printing station 19 fixed on the frame 9.
  • the frame 9 comprises a base 21 placed or fixed on a floor.
  • the frame 9 also comprises two uprights 23, 25 and a beam 27 mechanically connecting the two uprights to form a gantry 29.
  • the uprights 23, 25 are advantageously vertical.
  • the beam 27 extends for example along the pivot axis ⁇ 1, which is advantageously substantially horizontal.
  • the treatment stations 15, 17 are for example fixed on the beam 27 and adjustable in position relative to the frame 9.
  • the treatment station 15 is for example a plasma pretreatment station and comprises a plasma torch 31 adapted to be directed towards one of the objects 5.
  • the treatment station 15 is advantageously adjustable in position relative to the frame 9 so as to to have an adequate position relative to the turret 13.
  • the treatment station 17 is for example a drying station advantageously comprising a reactor 33 with UV (ultraviolet) radiation.
  • the printing station 19 comprises a support beam 35 fixed to the frame 9 and adjustable in height with respect thereto, a carriage 37 ( figures 2 and 3 ) slidably mounted on the support beam according to the pivot axis ⁇ 1, a plate 39 integral with the carriage, and a plurality of ink jet printing heads 41 mounted on the plate 39 adapted to eject ink jets 43 in a DD printing direction on the outer surface 7.
  • the print heads 41 are six in number, for example an impression of one of the four-color photo body type: yellow, magenta, cyan, black. Still in the example shown, two additional printheads can print in white for one, and deposit an overprint varnish for the other.
  • the printing station 19 comprises only four printheads, for a quadrichromy strict or less.
  • the printing direction DD is advantageously vertical.
  • Print heads 41 are analogous to one another and of the type described in the preamble of the present application, that is to say, adapted to spit the ink jets 43 from an advantageously substantially horizontal ejection plane. , the ink jets 43 of the same printing head 41 forming rows extending in a substantially horizontal alignment direction A.
  • the printing station 19 also includes drive members known in themselves and which will not be detailed here, to adjust the height of the print head 41 relative to the frame 9, and move the carriage 37 relative to the position of the support 35 along the pivot axis ⁇ 1.
  • the plate 39 supporting the printing heads is slidably mounted on a chair 40 ( figure 2 ) in particular according to the alignment direction A. This allows printing on objects 5 whose outer surface 7 has an extension greater than that of the printing heads 41 in the alignment direction A.
  • the turret support 11 advantageously has a cradle shape ( figure 1 ).
  • the turret support 11 comprises a central portion 45 on which the turret 13 is rotatably mounted about the axis of rotation ⁇ 2, and two end portions 47, 49 according to the pivot axis ⁇ 1 fixed on the uprights 23, 25.
  • Each of the end portions 47, 49 comprises for example a cylindrical pin 51, 53 respectively movable in a clip 55, 57 of the uprights 23, 25.
  • the machine 6 also comprises one or more members 59 for locking the turret support 11 in a desired inclination ⁇ about the pivot axis ⁇ 1 with respect to the frame 9.
  • the turret 13 comprises four object carriers 61A, 61B, 61C, 61D regularly spaced at 90 ° around the axis of rotation ⁇ 2 and adapted to carry the objects 5 and advantageously rotate respectively about four axes D1 , D2, D3, D4.
  • the turret 13 is movable successively between four positions relative to the frame 9, which are deduced from each other by a rotation of 90 ° about the axis of rotation ⁇ 2.
  • the slide 61A carries one of the objects 5 opposite the treatment station 15.
  • the slide 61B carries another of the objects 5 opposite the printing station 19.
  • the slide 61C carries another of objects 5 opposite the treatment station 17, that is to say in the reactor 33.
  • the object holder 61D is located opposite any treatment station and allows the loading or unloading of objects 5.
  • the turret 13 is adapted to carry each of the objects 5 successively from a loading point to an unloading point after having made a complete revolution, passing under the processing station 15, and then under the printing station 19 , and finally in the treatment station 17.
  • the object holder axes D1, D2, D3, D4 are for example defined respectively by a mandrel of the slides 61A, 61B, 61C, 61D.

  • the object holders are regularly spaced angularly around the axis of rotation ⁇ 2.
  • the pivot axis ⁇ 1 remains perpendicular to the axis of the object carrying object 5 located next to the printing station 19, and coincides with the two axes of the two object holders diametrically opposite with respect to the rotation axis ⁇ 2 and located next to the processing stations 15, 17. This allows to implement additional processing stations (not shown), located angularly between any two consecutive object-holders taken among the 61A 61D shown in the figures.
  • the relative positions of the processing stations 15, 17 and the printing station 19 relative to the frame 9 are first adjusted.
  • the inclination ⁇ of the turret support 11 is advantageously adjusted so that an upper generatrix G of the object 5 carried by the object-holder located opposite the printing station 19 (here the object-holder 61B) is parallel to the alignment direction A.
