Definitions

  • the invention relates to a multi-color printing unit for a Sheet-fed rotary printing machine, according to the preamble of Claims 1 and 3.
  • Such printing devices are e.g. by EP-B-0 431 068 known.
  • Another printing device is known from US-A-4 098 185.
  • To a blanket cylinder are several forme cylinders with their inking units semicircular arranged.
  • the blanket cylinder has a multiple Diameter of the forme cylinder.
  • An impression cylinder with a controllable gripper row works with the Blanket cylinder together.
  • the impression cylinder has simple, i.e. the same diameter as the forme cylinder.
  • the US-PS 30 41 966 shows a multi-color printing unit for a web-fed rotary printing press with a central one Impression cylinder and five printing units.
  • the printing units with Ink feed, inking roller, form cylinder and Blanket cylinders are not about an operating room accessible, which is easily accessible from one machine side, i.e. is accessible from the operator or drive side. It rather, the inking units must first be moved away together in an operating room for forme cylinders, blanket cylinders and Inking rollers to arrive.
  • An operating room for the four inking units of a multi-color printing unit according to DE 195 03 619 A1 is not one Machine side, i.e. from the operator or drive side accessible. Rather, it is only from the investor side that Accessible on the boom side or from above.
  • the invention has for its object a multi-color printing unit for printing on arched print carriers, e.g. out of paper.
  • a multi-color sheet-fed rotary printing machine can be produced in the most compact design. Nevertheless, good access to the ink fountain, anilox roller, inking roller, forme cylinder and the blanket cylinder is guaranteed. Even with sheet-fed rotary printing machines for a small format, for example DIN A3, there is enough space to be able to operate the machine well and to arrange imaging devices for the printing form (plate or film or the form cylinder itself). Four-color printing of the sheets is done in a single gripper closure. This enables a perfect color register. No continuous lifting and placing of inking rollers is necessary during printing.
  • So-called slot fastenings as well as clamp fastenings and sleeves can be used for fastening the covers of the inking rollers, the printing forms and the rubber blankets. Sleeves can also be used with anilox rollers. No dampening device is advantageously provided. It is therefore possible to use printing inks for "waterless” offset printing, UV printing inks, but also printing inks in which the dampening liquid or a chemically bound substitute for the dampening solution is contained in the printing ink even before it is filled into the ink fountain . Printing inks can also be used in which the dampening liquid or its substitute is supplied to the printing ink in the ink fountain. Of course, so-called “hot-melt” printing inks can also be used. The double printing units can be easily assembled from two single printing units.
  • the printing unit 1 according to the invention according to FIG essentially consist of: a base 2, a plurality of e.g. four printing units 6.1, 6.2, 6.3, 6.4 and one multi-field impression cylinder 8 with a plurality, e.g. five, controlled gripper rows 9, 11, 12, 13, 14 with the associated gripper pads.
  • the outer surface of the Back-pressure cylinder 8 can have an oleophobic coating.
  • Machine pages important for operating the printing units are: the first end face facing a sheet feeder, you opposite is the second one facing a sheet delivery End face; an upper side that gives access to the printing unit allowed from above. And finally a front side of the machine 4, commonly referred to as the "operator side”. you opposite is the back, which is commonly referred to as the "drive side” is referred to, because usually the drive motors on it are attached.
  • the printing unit 1 are from a sheet feeder (not shown) arcuate print carriers, e.g. made of paper, fed and after a multi-color printing one Sheet delivery (not shown) fed.
  • the printing unit 1 is advantageously free without being hindered by Side frames at least from one side over one Service room 5 accessible, i.e. from the "operating side” and / or the "drive side".
  • the "operating page” extends between the inside of the side frames of the "operating side” to the "drive side”. To this end at least the side frame of the "operating side” is like this recessed that free access to the operating room 5 is guaranteed.
  • the operating room 5 is the V-shaped arrangement of the Double printing units 3.1.3.2 (Fig.1) or through the space between the individual printing units 5.3, 5.4 (FIGS. 2 to 5) formed as soon as the double printing unit 3.3 has started up.
  • the double printing unit 3.1 has two Side frames 17, the double printing unit 3.2 two side frames 18, the double printing unit 3.3 two side frames 19, the Single printing unit 5.3 two page frames 20.1, the Single printing unit 5.4 has two side frames 20.2.
  • In the Double printing units 3.1, 3.2, 3.3 are each facilities for two independent color streams are available.
  • In the Individual printing units 5.3 and 5.4 are facilities for each a color stream is provided.
  • Double printing units 3.1, 3.2, 3.3 and Individual printing units 5.3 and 5.4 with so-called short inking units equipped, as shown by way of example in FIG. 1 are.
  • the side frames 17, 18, 19 of the double printing units 3.1 to 3.3 and in the side frames 20.1 and 20.2 of the Individual printing units 5.3 and 5.4 are for each of the ink streams each rotatably supported: one ink metering roller 21, one Ink application roller 22 with a rubber-elastic jacket 23 Formzlinder 24 and a blanket cylinder 26. You have them all the same effective circumference or diameter. They are preferably as a so-called single-circumference cylinder or roller executed. Forme cylinder 24 and blanket cylinder 26 could but also be designed as a so-called double circumference cylinder. Between the side frames 17, 18, 19, 20.1.20.2 and on attached to them inside is one for each color stream Ink feed device 27 is provided. The color flow is from the ink feed device 27 via the ink metering roller 21, the Ink application roller 22 on a printing form of the forme cylinder 24.
