Definitions
- the invention relates to a sheet printing machine according to the Preamble of claim 1.
- the ones to be printed Colors applied in individual printing units on the substrate can be trade solvent-based inks or by means of UV-curable colors.
- Cylinder guiding the bow and drums are sheet guiding devices in the form of Sheets, rods or with suction and / or blown air Assigned sheet guideways to make the sheets smear-free, i.e. without damaging the freshly printed page, to be transported between the individual printing units.
- UV-curable Color printed sheets is critical because of this type of ink drying a certain exposure time of UV radiation conditionally.
- sheet printing machines are used for printing of UV-curable colors UV lamps used.
- excimer emitters used, which is very narrow-band and thus quasi monochromatic Emit radiation.
- This type of drying has the Advantage that no ozone is generated, the substrate (substrate) is not damaged and otherwise with UV lamps Common odor does not occur.
- the biggest advantage such excimer emitter can be seen in that these are completely cold heaters. The substrate and There is no heat loss from machine parts.
- a sheetfed press with equipment for excimer UV drying is, for example, from the DE newspaper: Deutscher Printer No. 5 / 03.02.2000, pages g17 and g18 and DE 198 57 984 A1 known.
- a Sheet printing machines used to print sheets on both sides in one operation switchable from beautiful to beautiful and reverse printing and vice vers. These have a turning device at which of the previous Printing units on the face side printed sheets by means of Suckers and / or grippers at the end of the sheet captured and for printing hand over the reverse side to the following printing units become.
- a turning device is preferably designed a sheetfed press if this double sized cylinder and drums and the bow on the one-drum principle be turned. With such turning devices the turning drum has a device that detects the end of the sheet in the form of grippers and / or suction cups and take-over grippers on. Thanks to the double-sized cylinders (not easy large intermediate drums) result in arches low curvatures - the range of what can be printed Material gets bigger, the risk of smearing is less.
- DE 26 39 900 A1 describes a sheet-fed printing press with a single drum turn and dryer device known.
- the turning drum acts here with an upstream transfer drum an intermediate module downstream of the last face plate printing unit together.
- a dryer is arranged, as is the transfer drum.
- the object of the present invention is therefore a sheet-fed printing machine according to the preamble of claim 1 to expand so that two-sided printing of sheets printing inks to be treated with special drying devices is possible with little construction effort.
- the invention is preferably designed in UV ink printing, at the excimer emitter can be used. Through the excimer spotlights (one or more) below the turning drum but the curing of those previously applied in the straight printing units UV colors guaranteed.
- the face side and the respective pressure point downstream further excimer emitters are arranged. So the printing ink applied in each printing unit is already hardened before the turn, by the invention below the excimer emitter arranged on the turning drum takes place additional and a smear-free transport of the Arch ensures drying.
- the figure shows a part of a printing press with a. Turning drum 1 and one upstream of the turning drum 1 Impression cylinder 2 and a downstream impression cylinder 3. The direction of rotation of these cylinders or drums 1, 2, 3 is indicated by the arrows.
- a held by the gripper system of the impression cylinder 2 Sheet (at the front edge) is still in the printing unit this impression cylinder 2 printed.
- a previous one Sheet 5 is already through a first detection device the turning drum 1 has been detected at the rear edge.
- On further preceding sheet 6 is through the detection device to another gripper system of the double size Pass turning drum 1.
- Another preceding sheet 7 is already at the following through the face pressure gripper system Impression cylinder 3 has been passed.
- the principle of Turning is by means of a simply large turning drum well known - the type and training of the Devices on the rear edge of the device and the corresponding gripper devices form for the mode of operation the present invention does not matter.
- an excimer emitter 9 is arranged below the turning drum 1 below the turning drum 1 in a recess Arc guide path 8, an excimer emitter 9 is arranged.
- the Excimer emitter 9 acts on the face side of the now turned sheet 6. This results in a further curing of the previous printing units applied colors on the face side.
- the arch guideway 8 is a surface which by means not shown with suction and / or Blowing air can be acted upon. So there is one non-contact sheet guide, which lubricates the previously printed colors prevented. Continuing education according to the invention can be provided that also in the area of Excimer radiator 9 additionally applied by Blowing and / or suction air takes place.
- the impression cylinder 4 of the printing units upstream of the turn Another excimer emitter 10 is assigned to the acts on the face side of the sheet 4 just printed. It can be provided that all printing units one or more excimer emitters 10 each assigned. According to the respective pressure in the Printing unit already has a corresponding hardening of the straight applied colors.
