Definitions

  • the present invention relates to a coating group for applying a coating substance to a flat support.
  • the invention also relates to a printing machine for flat supports equipped with a group for applying a coating on flat supports.
  • a printing machine is used in the packaging industry for printing flat supports, such as sheets, or a continuous strip of paper or cardboard.
  • the machine includes several successive stations.
  • a first station located furthest upstream is an introduction station which introduces the planar support.
  • the insertion station supplies several printing stations, in the form of one or more printing groups placed one after the other. Each of the printing groups prints a specific color with an ink having the equivalent coloring.
  • a receiving station which collects the printed support with an image is provided at the end of the machine.
  • the printing machines include one or more printing groups, depending on the number of colors desired.
  • the support is moved longitudinally from upstream to downstream from the introduction station, towards the printing units, up to the reception station. In order to obtain a final quality image on the printed medium, it is especially necessary that all the patterns of different colors overlap exactly. It is also necessary that the printed dots are not distorted.
  • the selection of packaging is mainly based on a quality level criterion chosen according to the product to be packaged.
  • the control of the support after printing is still done visually.
  • the operator searches for all types of faults with careful observation of the printed medium and rejects the non-conforming supports.
  • the quality of the printing obtained depends not only on the quality of the printing machines, the quality of the inks used, but also on the quality of the media introduced at the machine input. Indeed, in the case of cardboard and for the same support, the surface may have irregularities, leading to different ink absorption properties, depending on the nature of the cellulose fibers constituting the support.
  • the printing affixed will show absences or surplus ink, variations in intensity of the color (s), and other defects. Indeed, when the drop of ink arrives at the surface of the support, its spreading will not be uniform. The image obtained is distorted by a multitude of printed dots, having a much larger surface area than that expected and visible to the naked eye, alternating with dots appearing to be printed correctly. In addition, the ink pigments are absorbed by the cardboard, resulting in a poorer pigmentation density leading to a dull image.
  • DE102008001003 discloses a coating group for applying a coating substance on a flat support, in a printing machine for flat supports, comprising an applicator cylinder, a screened cylinder and a supply system for supplying the screened cylinder.
  • a main objective of the present invention consists in improving the printing quality of a printing machine for flat supports, equipped with at least one printing unit.
  • a second objective is to produce a printing machine equipped with a group making it possible to coat all or part of the surface of the flat supports.
  • a third objective is to solve the technical problems mentioned for the machines of the state of the art. Yet another objective is that of successfully inserting a coating group into a printing machine for flat supports.
  • a coating group is used to apply a coating substance to an entire surface of a planar support or to a portion of a surface of a planar support, in a machine for printing of flat supports as defined in claim 1.
  • a flat support is defined, by way of non-exhaustive example, as being of a sheet, plate, continuous strip material such as paper, flat cardboard, corrugated cardboard, laminated corrugated cardboard, flexible plastic, for example polyethylene (PE), polyethylene terephthalate (PET), bioriented polypropylene (BOPP), or other polymers, or other materials.
  • the flat support is defined, by way of non-exhaustive example, as being a sheet intended to form a cutout, then a packaging box.
  • the quality of the printing obtained will be improved by the deposition of a coating substance and with recovery of this same substance to avoid excess .
  • the printing result will no longer be solely dependent on the starting medium.
  • the coating of the support means that the pigments remain on the surface, thus avoiding mottling phenomena.
  • a machine for printing flat supports equipped with at least one printing unit, comprises at least one coating group, having one or more technical characteristics described below and claimed.
  • a printing machine 1 is used to print supports of the plate element type, for example sheets of corrugated cardboard.
  • the machine 1 is a digital printing machine, which for example uses certain constituent elements described in the document US 6,471,430 .
  • the machine 1 notably comprises a set of four printing groups 2, arranged in line one after the other.
  • Each of the printing units 2 is provided with at least one digital print head, for example without contact, for example with ink jet. Black, cyan, magenta and yellow inks are printed on the sheets.
  • the leaves are introduced (Arrows F in Fig. 1 ) by a feed station (not shown), mounted upstream of the printing machine 1 (not shown).
  • the sheets are then picked up, transported, run longitudinally F, and exit F printed at a reception station (not shown), mounted downstream of the printing machine 1.
  • Two dryers 3, with evacuation pipes of steam, are placed downstream of the printing units 2.
  • the longitudinal direction is defined by reference to the path of the sheets in the printing machine 1, along its median longitudinal axis.
  • the upstream and downstream directions are defined with reference to the direction of movement along the path of the sheets, in the longitudinal direction throughout the printing machine 1.
  • the sheets to be printed are transported from upstream to downstream by an endless belt or metal band 4 which is mounted between a first upstream transverse cylinder 5 and a second downstream transverse cylinder 6. At least one of the two transverse cylinders 5 and 6 is rotated (Arrow R in Fig. 1 ) by means of a motor, which drives the strip 4.
  • the cylinders 5 and 6 and the strip 4 are mounted on a frame 7. The sheets remain pressed against the strip 4 in its upper path and pass under the printing units 2 and the drying modules 3, using suction boxes also called vacuum boxes.
  • the printing machine 1 comprises at least one coating group 8 and 9 for applying a coating substance to all or part of a surface of flat supports.
  • the printing machine 1 favorably comprises an upstream coating group 8.
  • This upstream coating group 8 is arranged upstream of the first printing unit 2, just after the feed station.
  • the upstream coating group 8 is placed in line with the upstream cylinder 5.
  • the upstream coating group 8 applies a coating, in this case on the entire surface of the sheets, blank of any printing. In this way, the surface is prepared with a pre-coating to subsequently receive the image to be printed.
  • the coating substance is an aqueous solution comprising water-soluble polymers.
  • a dryer 3 can be interposed between the upstream coating group 8 and the first printing group 2.
  • the printing machine 1 favorably comprises a downstream coating group 9.
  • This downstream coating group 9 is arranged downstream of the last printing unit 2, and downstream of the driers 3, just before the receiving station.
  • the downstream coating group 9 is placed in line with the downstream cylinder 6.
  • the downstream coating group 9 applies a coating, in this case on the entire surface of the printed sheets and thus on the printed image. In this way, the printed surface is covered with a post-coating to protect the image that has just been printed and dried.
  • the upstream coating group 8 and the downstream coating group 9 each comprise an applicator cylinder 11.
  • the applicator cylinder 11 is positioned transversely, ie perpendicular to the strip 4.
  • the applicator cylinder 11 is rotated (Arrow T at Fig. 3 ) during the production phase.
  • the applicator cylinder 11 is coated with a homogeneous layer of a porous material having elasticity and absorption properties of the substance, for example a flexible rubber 12.
  • the applicator cylinder 11 is able to be positioned against all or part of the surface of the sheet, in order to apply the coating substance, the pre-coating or the post-coating.
  • the sheets circulate in the gap left between the applicator cylinder 11 and the strip 4.
  • the coating substance, the pre-coating or the post-coating will thus be deposited on the sheets of corrugated cardboard on the grooves and on the bottom between the grooves.
  • the corrugated cardboard of the sheet will not be crushed by the flexible rubber 12 of the applicator cylinder 11.
  • the upstream coating group 8 and the downstream coating group 9 each comprise a screened cylinder 13, also known by the name of anilox cylinder.

  • the screened cylinder 13 is positioned parallel to the applicator cylinder 11.
  • the screened cylinder 13 is mounted substantially downstream side with respect to the axis of rotation of the applicator cylinder 11. When the screened cylinder 13 is in operation, it is positioned against the applicator cylinder 11.
  • the screened cylinder 13 covers the applicator cylinder 11 with the substance, coating, pre-coating or post-coating.
  • the upstream coating group 8 and the downstream coating group 9 each comprise a supply system 14.
  • the supply system 14 is provided with a substance reservoir, a pump, means for circulation of the substance (not shown), and a device 16 pressing against the screened cylinder 13 to supply it with substance.
  • the supply system 14 makes it possible to supply the screened cylinder 13 with the substance.
  • the device is advantageously of the doctor blade type 16.
  • the doctor blade chamber 16 is positioned parallel to the screened cylinder 13.
  • the doctor blade chamber 16 can be mounted upstream side with respect to the axis of rotation of the screened cylinder 13.

  • the doctor blade chamber 16 pivots (PU arrow in Fig. 2 ) thanks to a retracting cylinder 17 (U arrow in Fig. 2 ) and a pivot axis, from a low position to a position pressed against the screened cylinder 13. In the low position, the doctor blade chamber 16 is found for example parallel to the strip 4.
  • the doctor blade chamber 16 pivots (Arrow PD in Fig. 3 ) thanks to the jack 17 and to the pivot axis, from the position pressed against the screened cylinder 13 to the low position.
