Definitions

  • the invention relates to the auxiliary lubrication in printing units of rotary printing machines, preferably web-fed rotary printing machines.
  • it also relates to offset printing.
  • a preferred field of application is the newspaper printing and here preferably the printing of large newspaper editions. It can be advantageously used for printing with dampening solution, but also for printing without dampening solution.
  • the EP 1 442 884 A1 discloses a device by means of which a non-flowing medium, for example commercially available roller paste or roller grease, is finely distributed to the dry areas of a cylinder or a roller in the inking or dampening unit by means of blown air.
  • a non-flowing medium for example commercially available roller paste or roller grease
  • the invention relates to rotary printing machines with at least one printing unit, consisting of at least one printing cylinder and an inking unit for printing endless webs or sheets.
  • the printing unit further comprises a printing house's own detergent application device.
  • the dampening cylinder is also associated with a dampening unit, preferably a dampening unit operating with at least one dampening roller, by means of which the dampening solution is supplied to the printing cylinder.
  • the printing unit (s) is / are equipped with a device that allows the exact application of a lubricant in the range of dry rotating body sections without interrupting the production process. If the printing unit has its own detergent application device, the lubricant application device is additionally provided for this purpose. If the printing unit comprises a dampening unit, the lubricant application device is provided in addition to the dampening unit, but can use the dampening unit for the application of the lubricant, such that the lubricant is transferred separately from the dampening solution via one or more components of the dampening unit, in particular dampening roller (s) becomes.
  • the lubricant is a liquid which is preferably different from a washing liquid as used for conventional printing machine washing.
  • the usual dampening solution could be used as the lubricant, but preferably the lubricant also differs from the dampening solution.
  • the lubricant in the particularly preferred type of machine, a wet offset web-fed rotary printing press, a liquid which differs from both the washing liquid of the detergent application device and the dampening solution of the dampening system is thus used as the lubricant in a preferred embodiment.
  • the lubricant applicator comprises a system of e.g. Tubes which, starting from a reservoir and guided by at least one pump, are installed in the printing unit in such a way that along the outer surface of the shell of at least one body of the printing unit, e.g. an inking roller, a dampening roller or the printing cylinder, at least one tube of the applicator extends.
  • This tube is e.g. provided with bores which form outlet openings for the lubricant. In or at the outlet openings can be introduced nozzles for fine atomization of the lubricant.
  • the application of the lubricant can be carried out in time intervals, continuously or pulsating, it is preferred a continuous application of the lubricant.
  • the lubricant can be sprayed onto the dry rotating body section (s) under pressure, dripped by gravity or applied in another suitable manner.
  • the applicator preferably comprises at least one pump, preferably a separate pump.
  • This pump can be integrated in the control of the printing press, so that no lubricant is conveyed when the machine is at a standstill, during set-up and during emergency stop.
  • the lubricant is pumped by the pump and can be applied through the holes / nozzles or other facilities on the dry running sections / zones of a rotating body.
  • Zones designate the parts of the printing cylinder across its axial width which can be covered by a printing plate. Sections are parts of the cylinder which are larger or smaller than a zone but which may comprise zones entirely or in part.
  • the regulation of the delivery amount of the lubricant per unit time can be made for example by the surgeon by manual input according to experience before each printing, or be determined electronically, order quantity and / or order intervals being dependent on the conditions prevailing on the rollers, such as temperature and running speed. These conditions can be either the regulation in a model that is created on the basis of theoretical considerations or actual measurements on the machine, be given, but it is also possible to tap the current conditions prevailing on the rollers actual conditions using appropriate measuring devices currently, and the like obtained data to use as output data for a scheme.
  • Sections of the cylinder which have no pressure plate and no blank plate and in which no paper is running, advantageously allows the application device to selectively lubricate only individual zones or sections on the rotation body. This can be achieved in a device consisting of a pipe in that each individual outlet opening can be opened and closed independently of the other outlet openings. Thus, sections of any width can be sprayed specifically with lubricant, and it can be reacted to any document situation on the cylinder.
  • a plurality of parallel tubes may be provided, each lubricating only a certain zone, for example, per printing plate width, i. per zone, one tube.
  • built into the device after the pump advantageously built-way valves, which is applied to the tubes each alone or together with each other of the tubes with the lubricant. That is, it may be at a e.g. four-zone wide cylinders are lubricated either just any zone, or two or three arbitrarily combinable zones simultaneously.
  • the valves may be bi-directional actuators which are switchable between closed position and open position, but also continuously variable fluidic actuators or multiway actuators with more than two switch positions.
  • the valves can be controlled and switched electrically, magnetically or pneumatically.
  • movably mounted pipe sections can form the lubricant application device.
  • These can be selected by the operator manually or by the control of the press automatically, For example, by optical scanning on the surface of the printing cylinder depending on the width, the paper roll clamped for production, are moved axially.
  • pivotable spray nozzles can serve for lubrication in the dry-running area.
  • the disadvantage here is that when using multiple pivoting nozzles it can lead to overlapping areas, and the order quantity per cylinder surface unit decreases when pivoting with increasing pivot angle.
  • lubrication of the dry-running areas via e.g. Brush rollers or transfer rollers, as they are basically known from dampening.
  • the lubricant applicator can be introduced into the printing unit at any point where installation of the spray pipes is possible and useful. It is preferred that it runs in the axial direction along the inking rollers and / or inking rollers.
  • the lubricant application device may be arranged to the inking rollers that they simultaneously or reversibly an inking roller and / or an inking roller, or one or more of the inking rollers can apply lubricant.
  • the lubricant is preferably applied to a roller having the same direction of rotation as the forme cylinder, or to a roller of the inking or dampening unit, which is arranged between two other rollers, and having a direction of rotation, so that they after application of the lubricant forms the next gap with the roller lying in the direction of the forme cylinder.
  • a preferred solution is to guide the supply (s) of the lubricating fluid along the tube body (s) of the washing system through the printing unit, at least along or the rotary body (s), onto the or which directly applies the application device. This is particularly useful in cases where a printing unit with integrated washing device to be retrofitted to a device for applying lubricant according to the invention. Construction conditions on the printing press can also locally independent, separate arrangements of the feeders of the detergent applicator and the lubricant applicator condition.
  • An automatic cylinder washing device washes both ink residue and applied lubricant from the cylinders in a printing machine having a lubricant applicator.
  • the detergent which is sprayed onto the cylinders by means of the detergent applicator, passes through the roller mill and mixes with the paint residues and the lubricant. This mixture is collected at the lower end of the roll mill and passed into a tank. From there it can be disposed of or partially re-used, partially recovered or otherwise treated.
  • the mixture of detergent, paint and lubricant is scraped off or pulled off at the bottom roller. If it is intended to wash the dampening unit, the plate cylinder for the washing process by the printing cylinder and thus also by the dampening unit is turned off.
  • a lubricant-conveying pump can be designed as a central pump, so that a single pump supplies the device for applying the Maulaufstoffs only for a single printing unit, for the whole tower, for a bridge, for a section or for the entire printing machine with lubricant.
  • the targeted control of the currently required pipes for the application of the lubricant then takes place through the associated valves.
  • each outlet with its own reservoir, as well as the reservoir in this case itself as an applicator device, in which case a pump located in the reservoir could provide the necessary pressure, or the reservoir is pressurized with, for example, pneumatic pressure, which in turn affects the amount of lubricant dispensed through the outlet ports.
  • the lubricating or Maulaufstoff may differ in composition and effect of the guided in the cylinder washing liquid. It is then advantageous that both fluids have their own reservoir and not the same lines are used. In this case, it is particularly advantageous if both devices have their own pump unit. If a liquid is suitable for both tasks, lubrication and washing, it will suffice or suffice for a reservoir, a pump and possibly a pipe system.
  • the printing unit may further comprise a dampening unit, which provides the non-printing elements of the printing plate and the dummy plates, but not the dry-running ink roller sections, with a thin fountain solution film. Feeding dampening solution is necessary in wet offset printing. In the newspaper opening pressure, the expert distinguishes between centrifugal, turbo or brush dampening units that manage without a pump and spray dampening units with spray nozzles.
  • both systems can be combined, and then the common line system fluid in different intensity from a common reservoir the inking and dampening rollers are sprayed on, for example.
  • the in the field of printing plates and / or blank plates lying zones of the dampening rollers are sprayed with the amount of fluid that corresponds to the previously supplied by the dampening unit amount lying outside the paper web ink roller sections for the purpose of lubrication with eg more fluid.
  • the dampening unit and the cylinder washing device only one reservoir, a piping system and an applicator can be provided for all three tasks.
  • FIG. 1 shows a printing unit with an inking unit, a dampening unit and two printing cylinders 1 and 2.
  • the printing cylinder 1 is a forme cylinder
  • the printing cylinder 2 is a blanket cylinder which receives the print image from the printing cylinder 1 and prints on a web.
  • the printing cylinder 1 can be covered over its axial width with several printing plates (blanking or blanking plates).
  • the section through the arrangement in a region in which the printing cylinder 1 is covered with a printing form 3 can be seen.
  • a support structure 17 is arranged, which carries three tubes.
  • the middle tube 7 is the spray tube of a washing device by means of which detergent can be applied to the inking rollers.
  • tubes 8 are tubes of the lubricant application device, by means of which a lubricant can be applied to the ink rollers.
  • each color rollers applied with lubricant which are arranged between two other rollers of the inking unit.
  • one of the two rolls is seen in the direction of the forme cylinder 1 before (upward), the other behind (down) of the applied directly from the lubricant means with lubricant ink roller 4, 5.
  • Two of the rollers form a gap with each other. It is preferred if the direction of rotation of the inking roller 4, 5 is directed so that it forms a gap after application of the lubricant next with an upward, for example, the roller 6.
  • the direction of rotation of the inking roller 4, 5 would be opposite to the direction of rotation of the forme cylinder 1, that is to say the direction of rotation of the inking roller 4, 5 is equal to that of the printing cylinder 1 other rolls that meet the conditions defined above would be directly lubricated.
  • the in the FIG. 1 lubricated rollers 4, 5 are exemplary of any other possible roller of the inking unit.
  • FIG. 1 Another, in FIG. 1 not shown possibility is to apply in addition to the inking and rolling of the dampening partially or completely with lubricant. In this case, the statements made to the inking unit apply accordingly.
  • FIG. 2 shows the same situation as FIG. 1 , with the difference that the printing cylinder 1 carries no printing plate 3 in the section shown.
  • the printing cylinder 1 has no contact with the inking and / or dampening rollers in this area.
  • This figure illustrates once again that in this zone of the printing cylinder 1 there is no need for color transfer. Consequently, in the inking the color (not shown) screws are closed, which causes no color on the ink rollers 4, 5, 6 is performed, and thereby the Disadvantages of dry running can adjust.
  • Conventiontofore known manual application of secondary paste, spray or oil can be carried out automatically in the arrangement shown by the lubricant application device.
  • FIG. 3 shows a plan view of the combination of printing cylinder 1 and ink transfer roller 6. It can be seen that a paper web 9 is driven, which has only half of a possible maximum width. Consequently, the printing cylinder 1 is occupied only in one half with one or more printing plates 3, while the other half carries no printing plate or printing plates 3.
  • a simple wide pressure cylinder 1 is shown with two pressure zones next to each other.
  • the ink transfer roller 6 has contact only in the area with the printing cylinder 1, on which the printing form 3 sits. Accordingly, only this zone of the ink rollers is wetted with ink and / or fountain solution, the other rolling zones must / must be additionally lubricated.
  • FIG. 4 shows a possible arrangement of the lubricant applicator 8, 11 and the washing device 7 in a common carrier 17, which is formed in the example as a U-carrier.
  • the lubricant applicator consists of two mutually separate pairs of tubes 8, which are closed at their opposite ends and have outlet openings 11 in the end region.
  • the area of each tube 8 having the outlet openings 11 corresponds to the width of a zone of the pressure cylinder 1.
  • the upper pair of tubes 8 has a large distance between the two opposite ends. These two tubes 8 are suitable for the case as a lubricant application device when the printing cylinder 2 is centrally occupied with paper, but the two outer zones are not used for printing.
  • the lower tubes 8 are active when in addition to or only in the middle of the printing cylinder 1 is a freewheeling zone. Between the two tube pairs 8, the tube of the washing device 7 runs. In order to actually meet every possible situation concerning the dry running on the inking rollers 4, 5, 6, each of the spray tubes 8 is individually switched on and off, so that any Combination of spraying is representable.
  • Both tube pairs 8 can also be connected to one another in each case to a tube 8, wherein the tube 8 is closed at a location lying between the exit zones.
  • the individual order zones can be switched on or off individually and in any combination.
  • a solution with only a single tube 8 in which case it should be possible to open and close the outlet openings instead of the tube zones.
  • FIG. 5 shows the structure of the apparatus for lubricating a four-side wide ink roller 5, 6 in otherwise dry running area.
  • the ink roller washing system is also indicated, with only the supply line, the reservoir 18 and the spray tube 7 are shown for the detergent. It can be seen that washing and lubricating devices have independent fluid systems. From the reservoir 15, which is filled with lubricant, the fluid is conveyed by means of a pump 12 to the valves 13. These valves 13 are switched by a controller 14 either automatically by parameters such as web width, optical detection of the dry area on the ink roller 4, 5, 6 or manually by the operator. If they are open, the secondary flow agent can reach the respective tube 8 via the respective feed and lubricate the inking rollers 4, 5 therefrom.
  • FIG. 6 shows the side lubrication in a perspective view. You can see again the division of the ink roller 4, 5 in four zones (A, B, C, D), the corresponding arrangement of the tubes 8, the valves 13 and the pump 12. Should the printing cylinder 1 six or eight, or each have any other number of zones that can ever be occupied with printing plates 3 (printing plates and / or blank plates), it is within the meaning of the invention, then assign each of these zones according to a zone applicator 8 for lubrication.
