Definitions

  • the invention relates to a printing press, in particular an offset printing press, the printing unit of which has a plate, a blanket and a printing cylinder as well as an inking and dampening unit provided with ink and dampening application rollers and with a washing device which is in the washing operating position from a control device to the blanket cylinder is employed.
  • washing devices for cleaning the rollers or cylinders of an offset printing machine.
  • a washing device is to be used to clean the blanket cylinder.
  • a separate printing cylinder washing device is provided for cleaning the printing cylinder.
  • the plate cylinder is cleaned using the inking rollers.
  • the dampening unit can also be cleaned using the inking rollers, provided that an intermediate roller can be used to connect the inking unit and dampening unit.
  • the invention is therefore based on the object of creating a printing press of the type mentioned at the outset in which the outlay on equipment for washing operation is relatively low. Furthermore, simple handling should be provided.
  • both the blanket cylinder and the impression cylinder can be cleaned with only one washing device, provided the blanket cylinder and impression cylinder are in contact with one another. Since only slight contamination of the printing cylinder is to be expected in the production printing process, because the printing material is between it and the blanket cylinder, usually only the edges of the printing cylinder that are free of printing material take on color, so that it is not always necessary when washing the blanket of the blanket cylinder, also to clean the impression cylinder at the same time.
  • the distance between the blanket cylinder and impression cylinder is brought about. This can be achieved in a surprising manner with a device which is intended for a completely different operating mode. It is a so-called Provision of printing, which is used in production printing to compensate for the substrate thickness, that is, the distance between the blanket cylinder and the impression cylinder is set depending on the thickness of the substrate (eg paper thickness). If, during washing operation, the distance between the cylinders mentioned is reduced to zero by means of the pressure provided, the blanket washing device not only cleans the blanket of the blanket cylinder, but also the printing cylinder.
  • the pressure supply preferably has a remotely controllable, in particular electrical, drive.
  • the adjustment can then be carried out from the control panel of the printing press by pressing a button or the like, or can be carried out by a computer-controlled machine control.
  • the control device shifts the blanket cylinder and plate cylinder into a contact position so that the washing liquid can also pass from the blanket cylinder onto the plate cylinder.
  • a simultaneous cleaning of the blanket cylinder and plate cylinder is possible when the printing cylinder is switched off, that is to say in the spaced position.
  • the washing operation to be carried out with only one washing device, namely the blanket cylinder washing device mentioned, can also be extended to the dampening unit by the control device shifting the dampening application roller into contact position with the plate cylinder.
  • the washing liquid can then get from the blanket cylinder to the plate cylinder and from there via the dampening roller into the dampening unit.
  • Color residues can be washed out very well in this way and / or gum residues, as they remain in the dampening unit, are cleaned, provided the rubber coating is transferred via the dampening unit to the pressure plate of the plate cylinder.
  • the control device separates a dampening solution supply device from rollers of the dampening unit leading to the plate cylinder.
  • the separation point is preferably made between the dampening roller and a metering roller, which works together with an immersion roller of the dampening unit.
  • the dipping roller protrudes with part of its circumference into the a dampening solution box.
  • the control device connects the inking and dampening unit to one another via an intermediate roller, so that rollers of the inking unit can be washed with washing liquid supplied by the dampening unit.
  • the washing liquid coming from the blanket cylinder washing device can therefore reach the inking unit via the plate cylinder, the dampening application roller and the intermediate roller and clean the corresponding rollers there.
  • the control device switches off a ink delivery device from rollers of the inking unit leading to the plate cylinder.
  • the separation point can take place, for example, between a lifter roller and a roller interacting with it.
  • the lifter roller can periodically interact with an ink duct of the ink fountain of the printing press.
  • control device for washing the rollers of the inking unit turns the inking rollers on the plate cylinder.
  • the washing liquid is supplied to the inking unit in a shorter way via the inking rollers which interact with the plate cylinder.
  • the dampening unit can also be washed with the intermediate roller. It is also possible to use ink and dampening rollers on the plate cylinder for cleaning. It is possible to couple or decouple the inking and dampening units by means of the intermediate roller.
  • the invention further relates to a method for cleaning cylinders and rollers of a printing unit of a printing machine, in particular offset printing machine, the printing unit having a plate, a blanket and a printing cylinder and an inking and dampening unit provided with inking and dampening application rollers, and that is also provided with a washing device which is placed on the blanket cylinder for the washing process, and wherein in the washing operation the printing cylinder (37) is displaced from a printing supply which serves to compensate for the printing substrate thickness in the spacing or contact position to the blanket cylinder (36).
  • the relative position of the blanket cylinder and plate cylinder and / or plate cylinder and dampening roller and / or plate cylinder and inking roller (s) and / or an intermediate roller and the dampening roller or an associated inking roller is also freely controllable, depending on the control state, cleaning or preventing cleaning of the corresponding parts can be carried out from only one washing device.
  • the free controllability of the printing cylinder is carried out by means of a pressure supply which serves to compensate for the substrate thickness in continuous printing operation.
  • the provision of printing which is intended to serve a completely different purpose, is therefore used anew according to the invention in that it is used not in the printing process but in the washing process. Due to their adjustability, which can preferably be carried out remotely by means of a drive, both a contact position of the blanket cylinder and impression cylinder and a spacing position of these cylinders can be achieved. In this respect, the printing cylinder is either washed or not.
  • a dosing roller of the dampening unit interacting with a dampening solution immersion roller is switched off by the dampening application roller during the washing process, it is ensured that no washing liquid can penetrate into the dampening solution delivery device of the printing press.
  • the inking unit that is to say that during the washing process a jack roller of the inking unit interacting with an inking roller is switched off by an inking unit roller leading to the inking rollers, so that the penetration of washing liquid into the ink delivery device is prevented.
  • FIG. 1 shows a roller diagram of an offset printing machine, not shown in detail.
  • the roller diagram has an inking unit 1 and a dampening unit 2.
  • the inking unit 1 is provided with an ink fountain 3 which (not shown) has metering elements for setting zonal ink gaps. From the ink fountain 3, an ink fountain pen 4 doses ink during operation.
  • a pivotable lifting roller 5 interacts with the ink duct 4 and a driven distribution cylinder 6.
  • the dampening unit 2 has a dampening solution box 26 filled with dampening solution 27, wherein an immersion roller 28 with a partial section of its circumference is immersed in the dampening solution 27.
  • the dipping roller 28 interacts with a metering roller 29.
  • a rubber roller 30 is also provided.
  • Inking and dampening units 1, 2 also have further, driven cylinders 7, 8, 9 and 10. Furthermore, six rider and transfer rollers 11 to 16 and nine rubber rollers 17 to 25 are provided. An intermediate roller 31 can be used to couple the inking and dampening units 1, 2 by the intermediate roller 31 coming into contact with the rollers 30 and 18.
  • both ink and fountain solution can be supplied to a printing form 32.
  • the printing form 32 is a printing plate (not shown) mounted on a plate cylinder 33.
  • the transfer of ink and dampening solution from the inking unit 1 or dampening unit 2 for the printing plate is carried out by the rubber rollers 18, 20, 23, 25 and 30.
  • the rubber rollers 18, 20, 23 and 25 are therefore also referred to as the ink-transferring inking rollers 34 and the rubber roller 30 —in relation to the dampening solution 27 — as the dampening roller 35.
  • a blanket cylinder 36 and impression cylinder 37 are also provided.
  • the blanket cylinder 36 is associated with a washing device 38, which can be adjusted by means of a control device, not shown, in the contact position against the lateral surface, that is, against the blanket of the blanket cylinder 36.
  • the washing device 38 has two washing rollers 39 and a common roller 40 connecting the washing rollers 39.
  • a transfer roller 41 is provided which is in contact with the upper washing roller 39 and which can be supplied with washing liquid 43 by means of a spray device 42 or the like.
  • a doctor device 44 is associated with the roller 40, under which a collecting trough 45 is arranged.
  • the distance between the blanket cylinder 36 and the printing cylinder 37 can be set.
  • the setting is made according to the thickness of the printing material used (eg paper).
  • the pressure supply in the washing operation of the offset printing press is used to either a position of To produce blanket cylinder 36 and impression cylinder 37 or a spacing of these cylinders. There is therefore free controllability, with a device (pressure supply) known per se for a completely different operating mode being used in a new way according to the invention.
  • the control device already mentioned also allows free control of the individual rollers or cylinders of the offset printing press, so that a separate displacement of the blanket cylinder 36 and / or the plate cylinder 33 and / or the inking rollers 34 and / or the dampening roller 35 and / or the Metering roller 29 and / or the lifting roller 5 and / or the intermediate roller 31 is possible.
  • This free controllability also exists with regard to the pressure cylinder 37, either by means of the pressure supply or by means of a separate device for cylinder displacement.
  • washing operating modes can be carried out with the rollers or cylinders of a printing unit of the offset printing press shown in FIGS. 1 to 7:
  • the plate cylinder 33 and impression cylinder 37 are at a distance from the blanket cylinder 36, so that the washing device 38, which interacts with the outer surface of the blanket cylinder 36, only cleans the blanket stretched onto the blanket cylinder 36.
  • the printing cylinder 37 assumes a spacing position from the blanket cylinder 36 on account of a corresponding setting of the pressure supply.
  • the washing rollers 39 of the washing device 38 rest on the outer surface of the blanket cylinder 36. Furthermore, there is contact between the blanket cylinder 36 and the plate cylinder 33.

  • the washing device 38 is in contact with the outer surface of the blanket cylinder 36.
  • the impression cylinder 37 and blanket cylinder 36 assume a spacing position by means of the pressure provided.
  • a blanket cylinder 36 and plate cylinder 33 as well as the inking rollers 34 and the dampening roller 35 form a plate cylinder 33.

  • the one described Roller or cylinder position enables extensive cleaning of inking and dampening units 1, 2 as well as plate cylinder 33 and blanket cylinder 36. If cleaning of the printing cylinder 37 is also desired, the pressure supply can be adjusted such that the printing cylinder 37 is in contact with the blanket cylinder 36 occurs, whereby the washing liquid also wets the outer surface of the pressure cylinder 37.
  • FIG. 6 shows a roller position in which the inking and dampening units 1, 2 are coupled to one another via the intermediate roller 31 and the dampening roller 35 is in contact with the plate cylinder 33. Furthermore, blanket cylinder 36 and plate cylinder 33 are in contact with each other. The washing device 38 interacts with the blanket cylinder 36. The dampening solution delivery device 46 and the ink delivery device 47 are separated from the other components of the inking and dampening unit 1, 2.
