Definitions

  • the invention relates to a color transfer device of a printing press according to the preamble of claim 1.
  • ink is applied to a printing block positioned on a forme cylinder of the respective printing unit, using a so-called inking unit, depending on the type of ink.
  • a color transfer device By means of a color transfer device, the ink applied to the printing form is transferred to a printing substrate to be printed.
  • Color transfer devices known from the prior art are based either on so-called blankets or so-called rubber sleeves.
  • Rubber sleeves are made sleeve-like and are pushed to position them on a rubber cylinder in the axial direction of the blanket cylinder. Rubber sleeves have the advantage that non-ink-carrying gaps or channels in the area of the ink transfer device are avoided. Such rubber sleeves therefore favor a smooth rolling behavior of printing cylinders on each other and thus minimize cylinder vibrations.
  • rubber sleeves based color transfer devices require a high mechanical complexity and are therefore relatively expensive.
  • blankets In contrast, blankets must be stretched on the blanket cylinder in so-called chutes.
  • the relatively flexible blankets are received on a preferably metallic support member, wherein end portions of the support member are bent to form fixing elements, which serve to clamp the blanket on the blanket cylinder.
  • the fixing elements are part of the support element.
  • blanket non-color-transmitting column or channels When clamping formed between a so-called leading end and a so-called trailing end of the blanket non-color-transmitting column or channels, which adversely affect the rolling behavior of printing cylinders to each other and so can cause the same cylinder vibrations in relatively slender cylinders and at relatively high speeds.
  • blanket based color transfer devices are less expensive, the print quality that can be achieved is limited in terms of vibratory strips as compared to rubber sleeve based ink transfer devices.
  • the present invention is based on the problem to provide a novel ink transfer device of a printing press.
  • the carrier element and the fixing elements are designed to minimize the non-color-transmitting gap as separate or separate assemblies.
  • a color transfer device based on blankets is proposed with which non-ink-bearing gaps can be minimized.
  • the ink transfer device according to the invention non-ink-carrying gaps between the leading end and the trailing end of the blanket can be realized, which have a width between 0 mm and 1.0 mm in the circumferential direction. This makes it possible to combine the advantages of rubber sleeve-based ink transfer devices, namely the minimum tendency to oscillate thereof, with the advantages of rubber blanket-based ink transfer devices, namely the cost-effective implementation of the same.
  • FIG. 1 shows a detail of an ink transfer device 10 according to the invention in a state clamped on a blanket cylinder, the color transfer device 10 of FIG. 1 comprising a rubber blanket 11 and a carrier element 12 associated with the blanket 11. Blanket 11 and support member 12 are executed in the embodiment of FIG. 1 as separate assemblies.
  • the blanket 11 may be multi-layered.
  • the carrier element 12 can be embodied as a metal carrier, fabric carrier or as a fiber-reinforced plastic carrier. According to FIG. 1, in the tensioned state, the carrier element 12 is positioned radially inward and the blanket 11 radially outward. The carrier element 12 serves to receive the blanket 11. It should be noted that the carrier element 12 may also be an integral part of the blanket 11.
  • the ink transfer device 10 next to the blanket 11 and the support member 12 as separate modules running fixing 13 and 14.
  • the running as separate assemblies fixing 13 and 14 are used to tension the Kunststofftuchs 11 on the non dargestellen blanket cylinder. Due to the fact that the carrier element 12 and the fixing elements 13 and 14 are designed as separate assemblies, a non-ink-transferring gap 15, which forms in the tensioned on the blanket cylinder state between a leading end 16 and a trailing end 17 of the blanket 11 can be minimized such that it has a width between 0 mm and 1.0 mm in the circumferential direction.
  • a first fixing element 13 is assigned to the leading end 16 and a second fixing element 14 to the trailing end 17.
  • the fixing elements 13 and 14 are positioned radially inwardly relative to the carrier element 12, wherein the carrier element 12 is arranged both in the region of the leading end 16 and in the region of the trailing end 17 between the blanket 11 and the respective fixing element 13 and 14.
  • the fixing elements 13 and 14 have fastening sections 18 and 19, respectively, via which they are firmly connected to the carrier element 12.
  • the fastening sections 18 and 19 can be connected to the carrier element 12 by gluing, soldering or welding.
  • the fixing elements 13 and 14 furthermore have clamping sections 20 and 21 in addition to the fastening sections 18 and 19.
  • the clamping sections 20 and 21 are bent radially inwards in the tensioned state relative to the fastening sections 18 and 19 of the respective fixing element 13 and 14, respectively ,
  • the fastening section 18 and the clamping section 20 of the fixing element 13 assigned to the leading end 16 form an angle of less than 90 °.
  • a bending portion 22 and 23 of the respective fixing element 13 and 14 is formed between the mounting portion 18 and 19 and the clamping portion 20 and 21 of the respective fixing element 13 and 14, a bending portion 22 and 23 of the respective fixing element 13 and 14 is formed.
  • Blanket 11 and support member 12 have identical dimensions. According to FIG. 1, in the tensioned state on the blanket cylinder, the blanket 11 and the carrier element 12 at the leading end 16 and the trailing end 17 in the circumferential direction with respect to the mounting portion 18 and 19 and the respective bending portion 22 and 23 in the sense of an overhang. This makes it possible to minimize the circumferential width of the non-ink-transferring gap 15 such that it has a maximum width of 1 mm.
  • the fixing elements 13 and 14 are placed radially inwardly on the carrier element 12 via their attachment sections 18 and 19 in the region of the leading end 16 and of the trailing end 17.
  • This difference in thickness is compensated by a preferably formed as a foil compensation element 24.
  • the compensation element 24 is either positioned on the blanket cylinder or firmly connected to the carrier element 12.
  • the compensation element 24 extends between the attachment portions 18 and 19 of the fixing elements 13 and 14 over the entire length of the support member 12 and the blanket 11.
  • the compensation element 24 may be part of the fixing elements 13 and 14.
  • the fastening portions 18 and 19 of the fixing elements 13 and 14 can be flush-mounted radially inward into the support element 12. In this case, there is no difference in thickness and it can be dispensed with the compensation element 24.
  • the fixing elements 13 and 14 extend over the entire axial width of the ink transfer device 10 and thus of the blanket cylinder, on which the ink transfer device 10 is tensioned.
  • the non-ink transferring gap 15 may be sealed to prevent media from entering it.
  • FIGS. 3 and 4 show further exemplary embodiments of an ink transfer device 25 according to the invention.
  • the ink transfer devices 25 of FIGS. 3 and 4 essentially correspond to the ink transfer devices 10 of FIGS. 1 and 2, so that the same reference numbers are used for the same components. In order to avoid unnecessary repetition, only the details are discussed below, by which the ink transfer devices 25 of FIGS. 3 and 4 differ from the ink transfer devices 10 of FIGS. 1 and 2.
  • each of the two ends 16 and 17 can serve as a leading end or as a trailing end.
  • FIGS. 5 and 7 show a further embodiment of an ink transfer device 26 according to the invention.
  • the ink transfer device 26 of FIGS. 5 and 7 in turn has a rubber blanket 27 and a separately formed carrier element 28, which is designed as a metal carrier or fabric carrier or fiber-reinforced plastic carrier.
  • the ink transfer device 26 of FIGS. 5 and 7 has separately formed fixing elements 29 and 30.
  • a first fixing element 29 is fixedly connected to the carrier element 28 of the ink transfer device 26 in the region of a leading end 31 and a second fixing element 30 in the region of a trailing end 32. Between the leading end 31 and the trailing end 32, in turn, a non-ink-conducting gap 33 is formed.
  • Both the leading end 31 and the trailing end 32 associated fixing member 29 and 30 are fixedly connected via mounting portions 34 and 35 to the support member 28.
  • the fixing element 29 assigned to the leading end 31 in turn has a clamping section 36 angled relative to the fastening section 34.
  • the fastening section 34 and the clamping section 36 of the fixing element 29 assigned to the leading end 31 enclose an angle of less than 90 °.
  • the fixing elements 29 and 30 associated with the leading end 31 and the trailing end 32 engage in each other in the sense of a toothing or a zipper.
  • the fixing element 29 assigned to the leading end 31 has a plurality of recesses positioned next to one another in the axial direction, so that the fixing section 34 thereof extends over the entire axial width of the ink transfer device 26, whereas the clamping section 36 is formed only in sections.
  • the sections in which, in the embodiment of FIGS. 5 and 7, the fixing element 29 assigned to the leading end 31 has the clamping section 36 curved radially inward, are identified by reference numerals 37 in FIG.
  • the 31 has the leading end fixing element 29 has no radially inwardly bent clamping portion 36. Rather, the trailing end 32 associated with the fixing member 30 protrudes with corresponding projections of the mounting portion 35 in the recesses of the leading end 31st associated fixing element 29 into it. This results in the already mentioned teeth of leading end 31 and trailing end 32 and the fixing elements 29 and 30, wherein also in this embodiment, a minimum, non-ink-transferring gap 33 between the leading end 31 and the trailing end 32 can be realized.
  • the fixing elements 29 and 30 are mounted on their mounting portions 34 and 36 radially inward on the support member 28.
  • a difference in thickness caused thereby is compensated by a compensating element 39, which in turn can either be firmly connected to the blanket cylinder or the carrier element 28.
  • the compensation element 39 may be part of the fixing elements 29 and 30.
  • the fastening portions 34 and 36 of the fixing elements 29 and 30 can also be recessed into the support element 28 in a flush manner, radially inward. In this case, there is no difference in thickness and it can be dispensed with the compensation element 39.
  • a color transfer device for a printing machine for the purposes of the present invention, the leading end and trailing end can be stumped so as to provide between leading and trailing end of a blanket non-color-transmitting column whose width in the circumferential direction between 0 mm and 1.0 mm is.
  • fixing elements which serve to tension the ink transfer device on the blanket cylinder, relative to the blanket and a support member of the blanket are designed as separate assemblies. This makes it possible to extend the extension of blanket and support member in the circumferential direction, so that minimum gaps between leading and trailing end can be met.
