Definitions

  • the invention relates to an adapter sleeve for adapting the inner diameter of cylindrical hollow cylinders to the outer diameter of a cylindrical roller, comprising a sleeve body with a deformable base sleeve viewed from the inside out, optionally an intermediate layer and a cover layer.
  • the inventions also relate to arrangements comprising such an adapter sleeve and methods for mounting a hollow cylinder on a cylindrical roller using such an adapter sleeve.
  • sleeves and adapter sleeves are mostly used in the flexographic printing process.
  • ink is transferred to a printing medium via a printing forme by compressive stress.
  • letterpress and gravure printing it is one of the most important printing processes, especially in the packaging industry.

In addition, it can be used for different color systems, which ensures a more universal applicability.
  • flexographic printing machines are individually adapted to the respective area of application. They can be divided into the main groups of multi-cylinder and central cylinder printing machines. By using steel cylinders with the most varied of diameters, individual print repeats can be achieved.
  • adapter sleeves for bridging repeats are mounted on a steel cylinder.
  • a sleeve is mounted on the adapter sleeve.

  • the outer jacket surface 30 of the adapter sleeve 10 is formed by the outer side of the cover layer 5 and the inner jacket surface 32 of the adapter sleeve 10 is formed by the outer surface of the base layer 3.
  • the gas inlet 6 is designed in the form of an opening in the deformable base layer 3, preferably as a radially encircling ring of openings.
  • a channel 20 running in the radial direction runs in the deformable base layer 3 and the intermediate layer 4 and connects the gas inlet 6 to the first gas distribution system 1.
  • the first gas distribution system 1 comprises a plurality of channels 20, 22, of which in the Figure 3 only one channel 20 running in the radial direction to the first gas outlet 7 is visible.
  • the adapter sleeve 10 has further, in the illustration of Figure 3 non-visible first gas outlets 7, which can be supplied with gas via further channels through the first gas distribution system 1 and is preferably designed as a circumferential ring of openings. Gas flowing out of the first gas outlets 7 can be used to generate an air cushion which enables a hollow cylinder to be easily pulled onto the adapter sleeve 10.
  • the adapter sleeve 10 also has a second gas distribution system 2.
  • the second gas distribution system 2 is connected to the first gas distribution system 1 via the gas control unit 8 and has a channel 22 running in the axial direction and a radial channel 20 running in the radial direction in the direction of the deformable base layer 3.
  • the radially running channel 20 of the second gas distribution system 2 represents a cavity 12 which adjoins the deformable base layer 3. If pressurized gas is supplied to the second gas distribution system 2 via the gas inlet 6 and the gas control unit 8, pressure can be built up in the cavity 12 by gas flowing into the cavity 12. The pressurized gas located in the cavity 12 exerts a force on the deformable base sleeve 3, which causes a deformation of the base sleeve 3 and thus a reduction in the inner diameter of the adapter sleeve 10. If the adapter sleeve 10 is pulled onto a cylinder, the reduction in the inside diameter causes the adapter sleeve 10 to jam on the cylinder.
  • Figure 4 shows schematically a longitudinal section of the adapter sleeve 10 of a third embodiment.
  • the adapter sleeve 10 has a sleeve body with a deformable base layer 3, an intermediate layer 4 and a cover layer 5.
  • the adapter sleeve 10 of the third embodiment has a gas connection 13 as a gas inlet 6 on one of the end faces.
  • a compressed air line can be connected to the adapter sleeve 10 via the gas connection 13.
  • the gas connection 13 is connected to the gas control unit 8.
  • the gas control unit 8 can release or block a gas flow from the gas connection 13 to the first gas distribution system 1 and the second gas distribution system 2 as well as a third gas distribution system 11.
  • the first gas distribution system 1 comprises a plurality of channels 20, 22, of which in the Figure 4 only one channel 20 running in the radial direction to the first gas outlet 7 is visible.
  • the adapter sleeve 10 has further, in the illustration of Figure 4 first gas outlets 7, which are not visible and which can be supplied with gas via further channels through the first gas distribution system 1. Gas flowing out of the first gas outlets 7 can be used to generate an air cushion which enables a hollow cylinder to be easily pulled onto the adapter sleeve 10.
  • the air cushion can be influenced by controlling the gas flow via the gas control unit 8.
  • the second gas distribution system has a duct 22 running in the axial direction and a radial duct 20 running in the radial direction in the direction of the deformable base layer 3.
  • the radially running duct 20 of the second gas distribution system 2 represents a cavity 12 which adjoins the deformable base layer 3 . If pressurized gas is supplied to the second gas distribution system 2 via the gas connection 13 and the gas control unit 8, pressure can be built up in the cavity 12 by gas flowing in in the cavity 12.
  • the pressurized gas located in the cavity 12 exerts a force on the deformable base sleeve 3, which causes a deformation of the base sleeve 3 and thus a reduction in the inner diameter of the adapter sleeve 10. If the adapter sleeve 10 is pulled onto a cylinder, the reduction in the inside diameter causes the adapter sleeve 10 to jam on the cylinder.
  • the adapter sleeve 10 of the third embodiment shown has a third gas distribution system 11, of which the illustration in FIG Figure 4 a duct 22 running in the axial direction and a duct 20 running in the radial direction are visible.
  • the radially running channel 20 connects the third gas distribution system 11 to a second gas outlet 9, which is designed on the inside of the adapter sleeve 10 as an opening in the deformable base layer 3.
  • the adapter sleeve 10 has further second gas outlets 9, which in the Figure 4 are not visible. If a gas is supplied to the third gas distribution system 11 by appropriate activation of the gas control unit 8, this is conducted to the second gas outlets 9 and flows out there.
  • the gas flowing out at the second gas outlets 9 creates an air cushion on the inside of the adapter sleeve 10, which allows the adapter sleeve 10 to be easily pulled onto a cylinder.
  • FIG. 5 shows schematically a longitudinal section of the adapter sleeve 10 of a fourth embodiment.
  • the adapter sleeve 10 shown corresponds to that with reference to the Figures 2 and 3 described adapter sleeve 10 of the second embodiment, wherein between the deformable base layer 3 and the mouth of a radially extending channel 20 of the second gas distribution system 2, the cavity 12 is designed as a radially circumferential hollowed area 26 in the intermediate layer 4.
  • the hollowed area 26 allows pressure to be exerted on the deformable base layer 3 over a larger area, so that the inside diameter of the adapter sleeve 10 is reduced over a larger area.
  • Figure 6 shows schematically a longitudinal section of the adapter sleeve 10 of a fifth embodiment.
  • the adapter sleeve 10 shown corresponds to that with reference to FIG Figure 4 described adapter sleeve 10 of the third embodiment, wherein between the deformable base layer 3 and the mouth of a radially extending channel 20 of the second gas distribution system 2, the cavity 12 is designed as a radially circumferential hollowed area 26 in the intermediate layer 4.
  • the hollowed area 26 allows pressure to be exerted on the deformable base layer 3 over a larger area, so that the inside diameter of the adapter sleeve 10 is reduced over a larger area.
