Definitions

  • the invention relates to a dryer device for a sheet-fed rotary printing press, the device being particularly suitable for drying sheets coated in the printing press (inline coating).
  • a large number of drying devices for general solution to the problem are already known.
  • a generic device is known for example from DE 2 639 900 A1.
  • a drying device is then arranged between printing units in a special unit, which is further formed by a transfer cylinder and a downstream turning drum.
  • a drying device for a sheet-fed printing press which has a radiation dryer acting on a sheet guiding cylinder.
  • a shutter mechanism for closing the radiation dryer is actuated via a switching arrangement which interacts with the gripper channel.
  • DE-OS 2 412 493 Another device of this type is known from DE-OS 2 412 493, in which the radiation output of a dryer can be regulated.
  • a disadvantage of these designs is that, due to the fixed arrangement of the drying devices, the required heat input cannot be adjusted to the different sheet travel for different substrates. The result of this is that there is a reduction in quality (smearing) in the printing result, since the color to be processed or the coating to be processed in each case has not dried sufficiently. Since the sheet travel is also different in the case of a fixed arrangement of the drying device and in the processing of printing materials with different grammages, the respective distance between the transported sheets and the drying device also changes. Due to the different distances between sheet and drying device, heat losses occur, which leads to unnecessary energy consumption. Furthermore, the arrangement of special units is associated with an increase in the overall length of the printing press (increased space requirement).
  • the object of the invention is to eliminate the disadvantages mentioned above. This is solved by the marked part of the main claim. Further training results from the subclaims.
  • a major advantage of the solution according to the main claim is to be seen in the fact that specific drying is achieved depending on the sheet travel of the respective printing material.
  • the dryer device according to the invention is set to a minimum distance from the sheet run of the printing material. This shortens the drying time for paint or varnish and further improves the print quality.
  • the height-adjustable dryer device prevents burns (if the heat input is too high) or smearing (if the ink or varnish dries too little) of the substrate.
  • the radiation output is adapted to the actual heat requirement by means of the vertical or radial height adjustment of the dryer device.
  • the sheet guiding elements are connected to the radiator system and hot air dryer system arranged on the movable frame and are therefore also adjustable in height. By integrating sheet guiding elements, sheet guiding in the area of the dryer device is also taken over. Substrates that tend to detach or "flutter" at the rear edge of the impression cylinder during sheet transport are better guided on the impression cylinder by the hot air drying systems located close to the impression cylinder.
  • FIG. 1 shows a print finishing unit consisting of two coating devices which are arranged downstream of a sheet-fed rotary printing press for inline coating of printing materials.
  • the upstream printing units of a sheet-fed rotary printing press are followed by a first printing cylinder 6, to which a forme cylinder 7 is assigned.
  • the first printing cylinder is followed in the sheet running direction 9 by a sheet-guiding drum 11, which is followed by a second printing cylinder 6 with an associated forme cylinder 7.
  • the second pressure cylinder 6 is followed by another drum 11, which in the present example is the delivery drum of the boom.
  • Dosing systems for the paint to be processed are assigned to both forme cylinders 7 and are not to be described further here.
  • the height-adjustable dryer device is assigned to the second pressure cylinder 6.
  • the guide gear 8 consists of four fixed screw gears arranged on the frame, which are driven synchronously with each other via a traction mechanism gear. In another embodiment, the guide gear 8 can also be designed by synchronously operated coupling gears.
  • the dryer device consisting of a radiator system 3 and a hot air drying system 4 is arranged on the frame 1. Furthermore on frame 1 Sheet guiding elements 2, for example sheet guide rods, are arranged, which are assigned to the impression cylinder 6.
  • the operation of the device is as follows: coming from the upstream printing units, a sheet is fed via the first printing cylinder 6 and receives the print finishing in the form of a varnish in the area of a printing zone 10.
  • the sheet provided with a coating is transferred to the second printing cylinder 6 via the drum 11.
  • the second printing cylinder 6 is assigned the dryer device in the sheet travel direction 9 in front of the printing zone 10.
  • the varnished sheet is dried by the emitter system 3 and the hot air drying system 4, so that the sheet which has already been varnished is then given a further varnish via the associated forme cylinder 7 in the printing zone 10 of the second printing cylinder 6.
  • the sheet is then fed to the delivery in the sheet travel direction 9.
  • the dryer device is preferably movable in a vertical direction 5 from a control station.
  • the dryer device is moved closer to the printing cylinder 6 via the frame 1 and guide gear 8. If a sheet with a larger basis weight is varnished, the frame 1 with the dryer device is moved away from the printing cylinder 6 by an amount.
  • the distance of the frame 1 with the dryer device to the pressure cylinder 6 can be continuously adjusted via the guide gear 8. Since the sheet guiding elements 2 can also be moved in the vertical direction 5 with the frame 1, the sheet travel of the printing material on the printing cylinder 6 is improved.
  • the dryer device which can be adjusted in the vertical direction 5 by means of the frame 1 increases the efficiency of the drying by means of the radiator system 3 and the hot air dryer system 4, since the dryer device can be adjusted to the minimum most favorable distance from the printing material.
  • the dryer device is movable in the radial direction 12 to the pressure cylinder 6.
  • the guide gear 8 consists of two articulated quadrilateral, which are synchronized via one or two working cylinders 13 or one other drive can be operated.
  • the four-bar linkage can be designed, for example, as a rocker arm or parallel crank, so that the frame 1 with the radiator system 3 and the hot air dryer system 4 and the sheet guiding elements 2 can be pivoted on a coupling curve in the direction 12 and each side frame serves as a fixed member.
  • the mode of operation of this embodiment is analogous to the previously described embodiment according to FIG. 2.
  • the dryer device can now be pivoted and locked in a radial direction 12 on a coupling curve, preferably from the control station.
  • the dryer device In the case of sheets with a low basis weight, the dryer device is brought closer to the printing cylinder 6.
  • the dryer device is switched off by the printing cylinder 6.
  • a guide gear 8 By using a guide gear 8 in the manner of one or two articulated quadrilaterals, the distance between the dryer device and the sheet can also be set continuously.
