Definitions

  • the invention relates to a sheet printing machine according to the Preamble of claim 1.
  • DE 4343616 A1 describes a sheet-fed offset printing press in Series construction with printing units for face printing and one known upstream of the first printing unit.
  • printing units for the straight printing as well as the reverse printing unit forme cylinders are arranged on which printing forms can be clamped are.
  • the forme cylinders have fastening devices to shorten the set-up time on, by means of which a printing form is easy and in particular can be changed automatically.
  • To the ends of a printing form are each in the beginning of printing and the fastening device associated with the printing end of the printing form attached to the forme cylinder.
  • From EP 0654349 and DE 4215969 C2 is a in a straight printing unit
  • Form cylinder arranged sheet-fed offset printing machine known its fastening devices for automated changing a printing form are formed.
  • the starting edge of the print fastening device serving the printing form is designed to be cylindrical, in particular in the form of a Cylinder-fixed upper part with a radially movable lower part.
  • the rear fastening device which is also used as a tensioning rail is designed to be pivotable.
  • This rail is the print end with the one around the forme cylinder mounted printing form detectable and after building a Clamping force takes place the clamping of the printing form over assigned Spring elements.
  • the fasteners are preferred pneumatically and / or hydraulically operating actuators assigned.
  • the forme cylinder assigned and adjustable at these control devices a new printing form in the opened printing start fastening device by rotating the forme cylinder forward mounted on this and then on the printing end fastening device attached and tensioned.
  • the forme cylinder of a counterpressure functionally has that perform the same tasks, i.e. a printing form is on the To hold the start and end of the print and must be around the Outside circumference can be stretched.
  • a printing press the type mentioned rotates the forme cylinder of the counterpressure against the direction of rotation of the printing units for the Face printing.
  • the forme cylinders for the straight printing units are different to the forme cylinder of a printing press.
  • the different one Structure of the forme cylinder and / or those located therein Fasteners thus result in manufacturing costs negatively influencing variety of parts.
  • the object of the present invention is therefore a sheet-fed printing machine according to the preamble of claim 1 to expand, so that caused by the variety of parts Manufacturing effort can be significantly reduced.
  • the in an impression unit arranged forme cylinder with respect to cylinder body and the fastening devices which grip the ends of the printing form equal to the forme cylinder of the printing units for is the straight print.
  • the forme cylinder in the impression unit rotates only against the forme cylinders in the Printing units for straight printing.
  • the printing form in the counter printing unit is with the leading edge by a fastening device held, which in a straight printing unit End of print edge holds.
  • the print end edge will open the forme cylinder of the printing unit from the fastening device held, which in a straight printing unit Print start edge holds.
  • the forme cylinder in the impression unit only rotates counter to the direction of rotation of the forme cylinder in the straight printing units.
  • the present invention is also in a printing press with the straight printing units downstream and one with a Counter-pressure cylinder interacting form cylinder Coating unit applicable.
  • Figure 1 shows a sheetfed offset printing press with two printing units 1, 2 for straight printing.
  • the printing units 1, 2 for Face printing each act in a manner known per se 3 and a blanket cylinder 4 with an impression cylinder 5 (double size) together.
  • the first printing unit 1 for straight printing is an impression printing unit upstream, which is a forme cylinder 10, a blanket cylinder 9 and a cooperating with the blanket cylinder 9 Impression cylinder 7.
  • the transport of sheets to the counter pressure units via a transfer drum 8, between the printing units 1, 2 for straight printing are the sheets handed over by means of a further transfer drum 6.
  • the forme cylinder 3 in the printing units 1, 2 for straight printing and the forme cylinder 10 in the first printing unit 1 for Upstream upstream printing unit have the in the Figure 1 shown directions of rotation (during printing) on.
  • With the forme cylinder 10 act in a manner known per se Rolling a dampening unit 11 and an inking unit 12 together.
  • the Moist and inking units are the Moist and inking units not shown.
  • Figure 3 shows the forme cylinder 3, the blanket cylinder 4th and those interacting with the blanket cylinder 4 Impression cylinder 5 one of the printing units 1, 2 for straight printing in detail.
  • the forme cylinder 3 has an axially parallel Pit in a known manner trained fastening devices 15, 16, which is designed as a tensioning rail are on.
  • the fastening device 15 serves the Inclusion of the print leading and thus the start of printing DA associated edge of a printing form, not shown.
  • the fastening device 16 is used for receiving and Clamping of the trailing end and thus associated with the printing end DE Edge of a printing form.
  • the fastening device 15 pressure start DA
  • the one shown as a gap Detection area of the fastening device 15 for the Print start edge of a printing form can be used to clamp this Edge to be closed.
  • the one used to hold the printing end DE of a printing form Fastening device 16 is designed as a rail and overall pivotable about an axis. The end of the printing form can thus through the detection area of the fastening device 16 detected when swiveling forward, then clamped and through Swiveling the fastening device 16 back over not spring elements shown are tensioned.
  • Figure 2 shows the forme cylinder 10 with the axially parallel Pit and the fastening devices arranged therein 15, 16 in detail.
  • the direction of rotation of the forme cylinder 10 in The counterpressure is opposite to the direction of rotation of the forme cylinder 3 in the printing units 1, 2 for straight printing.
  • the sense of rotation of the cylinders 9, 10 in the counter pressure unit and 3, 4 in printing units 1, 2 for straight printing are shown in FIGS and 3 indicated.
  • the fastening devices 15 arranged in the cylinder body 16 are the forme cylinders 3, 10 in the printing units for straight printing 1, 2 or back pressure unit identical.
  • a comparison of the Figures 2 and 3 shows that the fastening device 15 in Printing unit 1, 2 for perfect printing of the forme cylinder 3 the start of printing DA is assigned, i.e. to accommodate the print start edge serves a printing form.
  • the fastening device serves accordingly 16 (swiveling) of the recording of the end of printing DE assigned edge of a printing form.
  • the assignment of the fastening devices is exactly the opposite 15, 16 on the forme cylinder 10 of the counter-printing unit. Because of the opposite direction of rotation (opposite the fastening device serves for the direction of rotation of the forme cylinder 3) 15 for receiving the printing end DE Printing form, whereas the swiveling fastening device 16 is assigned to the start of printing DA of the forme cylinder 10, that is, the leading edge of the printing form when printing takes up. Since the cylinder-fixed fastening device 15 for Recording the edge of the one assigned to the printing end DE Printing form is used, this is expediently with the printing end edge first inserted into this fastener 15.
