Definitions

  • the invention relates to a printing press, in particular a flexographic printing press, according to the preamble of claim 1.
  • Printing machines of this type which are designed in a modular design, can be used as single-color printing machines or in a row arrangement as multi-color printing machines. Each individual printing press forms a closed unit.
  • Printing machines of this type are primarily designed as flexographic printing machines, but can also be designed as gravure or offset printing machines.
  • UV-curing inks are said to have already been used in label printing in the offset process, the printed side of the labels, which were attached to a carrier web, being guided past UV lamps. Cooling screens were provided on the other side of the track.
  • the invention has for its object to design a modular construction printing machine, in particular flexographic printing machine, so that the use under UV radiation curing inks is possible and that these inks are cured reliably in the printing press without using sensitive web materials , such as plastic films or thin metal films, there is a risk of warping the web.
  • the cooling of the web on the cooling cylinder can ensure that plastic foils do not shrink or metal foils do not warp.
  • the registration accuracy is maintained, which is particularly important when using the printing press as a component of multi-color printing presses.
  • the hardening time of the paints can also be influenced favorably by the cooling cylinder, since the cooling cylinder can be acted on with heated water, i.e. with water that is at a higher temperature than the ambient temperature, but still has a cooling effect on the web.
  • Several radiators can be arranged around the cooling cylinder according to the modular principle. A modular design is also possible in this respect. This also enables adaptation to different web speeds.
  • the printing machine shown in Fig. 1 has a frame 1 which is supported against the floor 2.
  • a printing unit 3 is arranged, which in the present case is a flexographic printing unit.
  • the printing unit 3 has a printing form cylinder 4, to which a printing form is attached.
  • the printing form cylinder 4 is driven in the usual way by means of a motor, not shown. It is mounted on a vertically movable y-carriage 5, which can be adjusted vertically by means of a carriage-drive motor 6 and in particular can be adjusted downwards in the vertical direction.
  • the printing form cylinder 4 bears against a raster cylinder 7 which, together with a so-called chamber squeegee 8, is arranged horizontally on an x-slide 9.
  • the adjustment or infeed takes place by means of a handwheel 10.
  • the chamber doctor blade 8 is a known device which is designed like a flat hood and lies tightly against the cylindrical surface of the raster cylinder 7. Color is input into the interior 11 between the chamber doctor blade 8 and the anilox cylinder 7, which ink is transferred from the anilox cylinder 7 to the printing form attached to the printing form cylinder 4.
  • the printing form cylinder 4 continues to bear against an impression cylinder 12.
  • the raster cylinder 7 can be advanced against the printing form cylinder 4 on a carriage 12a in the x direction, that is to say in the horizontal, by means of an actuating device 12b.
  • a positioning cylinder 13 presses against the impression cylinder 12 from below.
  • the positioning cylinder 13 is moved by means of a positioning drive 14, which is designed as a hydraulically actuatable piston-cylinder drive, into the position shown in FIG. 1 against the impression cylinder 12 or downwards therefrom swiveled out position adjusted.
  • the flexographic printing machine is basically known.
  • the printing unit 3 receives a web 15 of material to be printed, in particular metal foil, plastic foil, but also paper or metal-laminated paper, via a bearing in the frame Deflection roller 16 supplied.
  • This web 15 is guided in the usual way through the printing unit 3 and printed there with ink which is crosslinked under the influence of UV radiation, that is to say from a liquid to a solid, stable state.
  • Such printing inks are known. They contain photoinitiators that trigger the chaining mentioned under the influence of UV radiation. Conventional drying by evaporation or evaporation of liquid such as solvents, water or the like. does not take place here.
  • the printed web 15 is fed from the printing unit 3 to a UV radiation and cooling unit 17.
  • a cooling cylinder 18 mounted in the frame 1, which has an inner cooling jacket 19, which in turn is connected to a cooling water supply line 20 and a cooling water return line 21.
  • UV lamps 23, 23 'are arranged which, as can be seen in FIG. 1, are arranged one behind the other in the web direction 24.
  • the cooling cylinder 18 can be driven in the web direction 24 by means of a drive, not shown.
  • the web 15 is guided over a further deflection roller 25 which is mounted in the frame 1 such that the wrap angle ⁇ of the web 15 around the cooling cylinder 18 is relatively large. In the present case, the wrap angle is slightly larger than 180 °. From there, the web 15 is guided to a deflection roller 26 located in the lower region of the frame 1, via which the web 15 is guided out of the frame 1.
  • FIG. 2 it can be seen that several UV lamps can be provided as required.
  • a modular construction is also possible here.
  • the two UV emitters 23, 23 ' provided in FIG. 1, in the exemplary embodiment according to FIG. 2 there are in each printing machine four UV lamps 23, 23 ', 23'',23''' attached to the frame 1 one behind the other in the web direction 24.
  • the UV radiation applied per unit of time to the web 15 and thus the color located there per unit area can be well adapted to the actual needs .
  • the web 15 also heats up under UV radiation.
  • cooling by the cooling cylinder 18 is provided.
  • optimal cooling of the web 15 can be achieved by the choice of the temperature of the cooling water, which can also be slightly preheated compared to ambient conditions, the large wrap angle in particular also leading to a cooling section which is long in relation to the web direction 24.
  • Intensive cooling is particularly important when printing on plastic films or very thin metal films, in particular very thin aluminum films, since the films mentioned lose their dimensional stability under the influence of heat.
  • Plastic films can shrink; Metal foils can stretch or warp.
  • cooling cylinders 18 of different diameters can be used, whereby the length of the effective cooling surface and the surface over which the UV lamp can be used can be influenced.
  • Every printing press is a self-contained unit, in which not only printing, but also the ink curing under UV light is completely cured.
  • the web 15 will be guided with its unprinted side over the outer circumference 22 of the cooling cylinder 18, while its printed side faces the UV lamps 23, 23 ', 23' ', 23' ''.
