Definitions

  • the invention relates to a printing unit for a printing press with a ink-bearing cylinder provided with a cup, interacting with a doctor blade, according to the preamble of claim 1.
  • JP-A-57207073 shows an intaglio forme cylinder carrying a layer of a thermoplastic synthetic rubber. This layer is charged positively with a charger attached to the cylinder. During the subsequent selective heating in accordance with a recording signal, wells are formed at the heated points. After unloading the layer, it smoothes out again when heated again. The device requires potential differences for the formation of wells, and the layer can only be deformed in the heated state. The amount of equipment required is correspondingly high.
  • the invention has for its object to design a printing unit with little technical effort so that the amount of ink guided by the cylinder can be changed without wear.
  • the gravure forme cylinder 1 has an intaglio printing cylinder 1 and an impression cylinder 2, between which the web 3 to be printed is passed.
  • the gravure forme cylinder 1 is partially immersed in an ink pan 4.
  • a doctor blade 5 can be set on the gravure forme cylinder 1.
  • the gravure form cylinder 1 has, cf. 3 and 4 on a metallic core 6, on which a porous, volume-changing intermediate layer 7 is applied, for example by plasma spraying.
  • a layer 8 made of a material with a temperature-dependent shape memory is applied on the outside to the intermediate layer 7.
  • Materials with a temperature-dependent shape memory can be constructed on a metallic basis, as described, for example, in the "Southren” magazine in 1987, pages 58 to 61 and 70 to 73, or on a plastic basis, as described in the "highTech” magazine, issue 4 / 1989 are described.
  • a temperature control device 9 is provided in front of the circumference of the intaglio printing cylinder 1.
  • the temperature control device 9 has As shown schematically in Fig. 2, a plurality of heating elements 10 arranged side by side in the form of very small resistors. The structure of such heat sources is described in the journal "Feintechnik und Meßtechnik” 95 (1987) 7 pages 433 to 435.
  • 3 shows that a multiplicity of cups 11 have been introduced into the layer 8. This can be done, for example, by mettling, that is, a tensionless deformation of the gravure cylinder 1.
  • 3 shows the shape of the layer 8 in a first shape state.
  • Each circumferential row of cups 11 is assigned a heating element 10 in the temperature control device 9, as is shown schematically in FIG. 2. If a heating element 10 is switched on, it heats the area of a well 11 of the layer 8. The layer 8 consequently deforms in this area and assumes the second shape state shown in FIG. 4, in which the respective well 11 disappears and the layer 8 forms a section of a cylinder jacket in the area of the well.
  • the porous intermediate layer 7 ensures that the outer diameter of the gravure cylinder 1 does not change during the transition from one to the other.
  • the intermediate layer 7 can advantageously also consist of a material with a temperature-dependent shape memory.
  • the line 5 shows the change in the shape of a material with temperature-dependent shape memory versus temperature.
  • the line a shows that the first shape state F 1 is retained until a temperature T 1 is reached.
  • T 2 is the second Shape state F 2 reached.
  • the second shape state F 2 remains until a temperature T 3 is reached which is below the temperatures T 1 and T 2.
  • the first shape state F 1 is only reached again when the temperature T 4 is cooled further. Between the temperatures T 1 and T 3, that is to say in the section ⁇ T, the given shape state thus remains unchanged. If the range of the usual working temperatures .DELTA.T * of the printing press lies within the range .DELTA.T, the shape of the area in the area of each individual well remains unchanged during the operation of the printing press.
  • a blanket cylinder 20, a plate cylinder 21 which can be covered with an offset printing plate, an application roller 22 with a flexible ink-accepting surface and a cylinder 23 serving as anilox roller are provided.
  • a dampening unit 24 can be set on the plate cylinder 21.
  • the cylinder 23 is supplied with ink by a doctor blade 25.
  • a temperature control device 26 is also arranged at a free location on the circumference of the cylinder 23.
  • the temperature control device 26 consists of a resistance heating element which extends over the entire width of the cylinder 23. If desired, the heating element can also be divided into zone-wide heating elements that can be switched on and off individually. Basically, there is also the possibility of using a temperature control device according to FIG. 1.
  • a given control of individual cells is not always necessary with anilox rollers.
  • the cylinder 23 has a hard metallic core 27 to which a layer 28 made of a material with a temperature-dependent shape memory is applied.
  • the layer 28 is expediently applied as a porous layer by plasma spraying. After it has been applied, it is clamped by tensionless deformation with a cup 29, cf. Fig. 7 provided. This also ensures that the outside of the layer 28 passes through in a closed manner.
  • the wells are introduced in a state defining the first shape Temperature T 4. Then the temperature of the layer 28 is brought to the value T 2, at which it assumes the second shape.
  • the cells 29 'of the second shape state are then given the desired final shape. This can again be done, for example, by mettling.
  • the inner porosity of the layer 28 in the first shape state is necessary in order to prevent a change in the outer diameter when changing to the second shape state.
  • the cylinder 30 is rotatably mounted on a fixed axis 31 and in turn has a porous layer 33 made of a material with a temperature-dependent shape memory that is applied to a metallic core 32. Cups 34 are introduced into the layer 33.
  • the cylinder 30 has an inner cavity 35 which is connected to a liquid circuit, for example a water circuit 38, via bores 36, 37.
  • a heat exchanger 39 in which the water flowing through can be cooled.
  • a feed pump 40 is also provided in the water circuit 38 to maintain the flow.
  • a second heat exchanger can also be provided to increase the temperature of the water cycle.
  • the layer 33 is transferred from one shape state to the other by heating the circulating water of the water circuit 38.
  • the water of the water cycle can be cooled or the temperature for reaching the first shape is such that it is reached automatically after the printing machine is switched off.
  • FIG. 11 shows a further coating.
  • a porous layer 51 made of a material with a temperature-dependent shape memory is applied to a hard core 50 of a cylinder, as is the case with the arrangement according to FIGS. 7 and 8. Cups are provided in layer 51, which are in the first shape 53 and 53 'in the second form.
  • an elastically deformable wear protection layer 52 is applied to the outside of the layer 51.
  • the wear protection layer 52 is only a few ⁇ m thick and expediently consists of TiN, TiAlN or TiCN.
  • FIG. 12 A further variant is shown in FIG. 12.
  • depressions 61 are machined into the outer surface of a hard core 60 of a cylinder.
  • the layer 62 made of a material with a temperature-dependent shape memory is designed as a thin-walled sleeve applied to the core.
  • layer 62 thus forms part of a cylinder jacket.
  • wells 63 form in the area of the depressions 61.
  • the depressions 61 are dimensioned such that they accommodate the layer 62 forming the wells 63.
  • This configuration is suitable not only for anilox rollers but also for gravure cylinders.
  • the layer 62 forms flatter cells in the first shape, as is the case with the arrangement according to FIGS. 7 and 8. Then it can be used for anilox rollers.
