Definitions

  • the invention relates to a printing press, in particular a web-fed rotary printing press, according to the preamble of claim 1.
  • DE-A-24 53 518 describes a generic printing machine in which water is sprayed onto the impression cylinder and this is cleaned with brushes.
  • GB-A-2 047 167 describes a device for cleaning an image transfer cylinder (blanket cylinder) by means of a cleaning cloth, which is unwound from a supply roll, wound onto a storage roll and brought into contact with the cylinder between which water and a hydrocarbon are deposited - Solvents are sprayed.
  • a cleaning cloth is known from DE-U-87 07 392, which is brought into contact with a cooling roller of a printing press and wipes and transports oil from the circumference of the roller. It is a dry wipe that is not moistened.
  • the object of the invention is to reliably prevent contamination of the impression cylinder.
  • the measures advantageously not only enable permanent cleaning of the impression cylinder, but also result in permanent moistening of the impression cylinder.
  • the damp film on the impression cylinder makes the impression cylinder ink-repellent and therefore advantageously prevents ink from being deposited on the impression cylinder right from the start or in any case counteracts such ink deposit. If, in particularly difficult cases, the impression cylinder should nevertheless take on color, it is wiped off immediately, which counteracts the build-up of color.
  • the measures according to the invention therefore ensure that the impression cylinder remains clean and that interruptions to cleaning the impression cylinder can be eliminated.
  • the wipe can expediently be moistened by means of a moistening device arranged upstream of the contact point with the counter-pressure cylinder, which preferably has spray nozzles directed onto the wipe.
  • a further expedient measure can consist in the fact that the wiping cloth is guided in the area of the contact point with the impression cylinder via a pressing member which is preferably designed as an inflatable bellows.
  • these measures enable the wiping cloth to be reliably engaged and, on the other hand, the wiping cloth is put down from the counter-pressure cylinder, which results in the wiping cloth being transported in the unloaded state and thus relieving the transport mechanism.
  • Humidification can be done with water.
  • the dampening solution which is also required in the dampening units and has particularly good ink-repelling properties can expediently be used.
  • the printing machine on which FIG. 1 is based consists, in a manner known per se, of two double offset printing units 1, 2, each with an impression cylinder 3, on which two transfer cylinders 4, which are designed here as rubber cylinders, are employed, which interact with a respectively assigned plate cylinder 5.
  • Arrangements of the present type enable a diverse paper guidance.
  • a paper web 6 or 7 is printed on one side on each double printing unit 1 or 2, which was previously printed on the other in one upstream printing unit Page should have been printed. This shortly before printed side of the paper web 6 or 7 comes to rest on the respectively assigned impression cylinder 3.
  • a wiper device 8 is assigned to it, which wipes its circumference and at the same time moistens it, thereby making it clean and ink-repellent.
  • the wiping device 8 is located in a circumferential section of the respectively associated impression cylinder 3, which is not wrapped around by the paper web 6 or 7. In the case of the left double printing unit 1, this is the area between the upward and downward movement of the paper web 6, which is fed in and out again, from the outside. In the right double printing unit 2, the paper web 7 is fed from the inside and discharged inwards.
  • the wiper device 8 could therefore be arranged in the area between the two impression cylinders 3.
  • the wiper device 8 is also arranged in the area on the outside, ie in the area of the side of the associated impression cylinder 3 facing away from the other impression cylinder, in the right double printing unit 2, as is also the case in the left double printing unit 1 is.
  • the paper web 7 is accordingly guided in the form of a loop 7a around the wiper device 8.
  • the wiping devices 8 are provided behind deflecting rollers 19, which can also be assigned a wiping device of the type mentioned above in problematic cases.
  • the wiping device 8 contains a wiping cloth 9 made of fleece, which, as can best be seen from FIG. 2, can be unwound from a supply roll 10 and wound onto a storage roll 11.
  • the supply roll 10 interacts with a button 12 which triggers a signal when the supply of cloth runs out.
  • the wiping cloth 9 runs over a pressing member 13 opposite the associated counter-pressure cylinder 3, which brings the wiping cloth 9 into engagement with the circumference of the assigned counter-pressure cylinder 3 with a strip-shaped section.
  • the pressing member 13 is designed as an inflatable bellows, which presses the wipe 9 against the impression cylinder 3 in the inflated state. In the relieved state, the wipe 9 can lift off the impression cylinder 3. This makes it possible to relieve the wiping cloth 9 running in the opposite direction to the associated counter-pressure cylinder 3 during forward feed, which also relieves the feed mechanism.
  • the advancement of the wipe 9 is accomplished here by means of a reciprocating piston 14 connected to the storage roller 11 via a lever mechanism.
  • the supply roll 10 can interact with a brake or a lock, which is released when the reciprocating piston is activated.
  • the wiping cloth 9 is transported forward step by step. The required number of steps per unit of time can be set depending on the contamination of the back pressure cylinder.
  • the wiper device 8 also contains a moistening device for moistening the wipe 9, which in turn is intended to moisten the associated impression cylinder 3.
  • This moistening device consists here of a nozzle bar 15 which grips behind the wiping cloth 9, is arranged above the contact zone between table cloth 9 and impression cylinder 3 and has spray bars 16 distributed across the width of the wiping cloth and directed obliquely downwards onto the wiping cloth 9 running onto the pressing member 13. These are from a protective plate 17, which has a drip edge arranged above the contact point between wipe 9 and pressing member 13 or impression cylinder 14.
  • the nozzle bar 15 can have a collection chamber assigned to all the spray nozzles 16, which is initially filled with moist liquid and then blown out by exposure to compressed air, which results in good atomization.
  • the wiping cloth 9 is moistened with each transport step and, if necessary, between two steps.
  • the supplied dampening fluid is to be dosed so that the dampening film produced on the impression cylinder 3 does not weaken the paper web 6 or 7.
  • the dampening fluid can be water. In offset machines, such as here, the dampening solution also used in the dampening units can be used as the dampening liquid.
  • the moistening device 8 is accordingly connected to a dampening solution tank. When water is used, it is simply connected to the mains. The connection is made via a connecting piece 18 provided with a screwable sleeve.
  • the entire wiper device 8 is accommodated on a frame 20 with two lateral end plates, which are bridged by cross members and can be detachably fixed to the side walls of the printing press.
