Definitions

  • the present invention relates to an apparatus for cleaning inking and printing rolls and of the type specified in the introduction of claim 1.
  • DE 9106454U1 describes an apparatus for cleaning items such as inking rolls and other printing unit parts for printing machines by using a water-based cleaning liquid, the apparatus including a cabinet configured as a liquid tight vat with a cover and a mesh-formed support face for items to be cleaned, a number of nozzles adapted to spray the items and a pump arranged to supply the nozzles with a cleaning liquid which is recirculated by sucking from the bottom of the vat-shaped cabinet at which a filter unit with one disposable filter is inserted between a suction branch from the vat and the nozzles.
  • the cleaning apparatus according to the invention is peculiar in that the bearing arrangements at a first end of the cleaning chamber are constituted by a projecting, cantilevered mandrel with engagement means which are adapted to engage and support an inking or printing roll and to fix an end part of the inking or printing roll, the mandrel and the engagement means being connected with a drive motor, the apparatus further including a separate wheel-supported transport device for transporting inking or printing rolls between the cleaning apparatus and a printing unit in a substantially horizontal, cantilevered position, in that the cleaning chamber is provided at a second end with an opening through which insertion and extraction of inking and printing rolls occur.
  • the cleaning apparatus according to the invention may advantageously be designed such that a laterally projecting support with bearing is provided at the second end of the cleaning chamber, the bearing adapted to support an opposing end part of the inking or printing roll.
  • the cleaning apparatus according to the invention is preferably designed such that the projecting, cantilevered mandrel is provided with preferably longitudinal lamellae in that the mandrel is adapted to bear on the internal face of the substantially tubular inking or printing rolls, and that at the first end of the cleaning chamber, the engagement means are constituted by a number of lamellae which together with the lamellae on the mandrel form a ring with a diameter corresponding to the inner diameter of the inking or printing roll.
  • the support bearing is constituted by a central projecting journal of a short cylindric body with axial lamellae arranged to engage between the lamellae of the mandrel.
  • the separate transport device has an upper support frame part with an upwardly projecting end part from which a cantilevered, horizontal support for an inking or printing roll extends to an opposing end part of the upper support frame part which is arranged vertically adjustable relative to a wheel-supported lower support frame part.
  • the cleaning chamber is adapted for simultaneous cleaning of two or more inking or printing rolls arranged in parallel
  • the separate transport device is correspondingly adapted for simultaneous transport of two or more inking or printing rolls arranged in parallel.
  • Figs. 1-3 show an embodiment of a cleaning apparatus 2 according to the invention, the apparatus 2 with associated transport device 24 shown and described as adapted for cleaning one inking or printing roll 4 at a time, but which, cf. claim 6, can be adapted to clean and transport, respectively, two or more inking or printing rolls 4 at the same time, as the cleaning chamber 6 and the transport device 24, respectively, relatively simply can be extended to handle the desired number of inking or printing rolls 4 simultaneously.
  • FIG. 1 appears how an inking or printing roll 4 by means of a transport device 24 arrives at the cleaning apparatus 2, supported on a projecting support 40 that project horizontally from an upwardly projecting end part 38 of an upper support frame part 36 of the transport device 24, which also includes lower support frame part 42 with swivelling wheels 44.
  • the upper support frame part 36 of the transport device 24 may suitably be vertically adjustable relative to the lower support frame part 42, as the corner connections between the upper support frame part 36 and the lower support frame part 42 may be constituted by telescoping leg supports 50 such that the vertical adaptation between the transport device 24 and the insertion opening 26 to the cleaning chamber 6 may occur completely trouble-free.
  • the transport device 24 is provided with its horizontal support 40 with the inking or printing roll 4 opposite the opening 26 and aligned with a horizontally projecting support in the cleaning chamber 6.
  • Fig. 3 it is then seen how the inking or printing roll 4 is on its way into the cleaning chamber 6.
  • Fig. 4 shows how and end part 16 of the inking or printing roll 4 can be inserted over engagement means 14 in the form of flexible lamellae 30 which together form a ring and which are adapted to expand radially by axial displacement of an internal cone.
  • Figs. 5-7 show how an opposing end part 22 of the inking or printing roll 4 is provided with a journal 32 on a cylindric end part with axial lamellae 34 intended for insertion into an open end part 22 and between the horizontal lamella supports 28 internally of the inking or printing roll 4 such that the journal 32 can be supported on a laterally projecting support bearing 20.
  • Figs. 8 and 9 show the cleaning apparatus 2 with inking or printing roll 4 inserted, i.e. ready for starting the cleaning procedure itself if only the lid 46 with the semi-circular lid 48 for the cleaning chamber 6 has been pivoted down to closed position, cf. Fig. 10 .
  • Figs. 12 and 13 serve to illustrate how the engagement means 14, 30 are drivingly connected with an electric gear motor 18 via a gearing.
  • Fig. 14 shows a projecting, cantilevered mandrel 13 which is rotatably seated at the first end of the cleaning chamber 6, and which is drivingly connected with the electric drive motor 18.
  • Fig. 15 appears an inner end part of the mandrel 13 which between the longitudinal lamellae 30, 34 consisting of an anti-friction material is provided with short lamellae 14 that act as the indicated engagement means as they ensure a firm and rotationally rigid connection between the mandrel 13 and the inner side of the tubular inking or printing rolls 4. In the art these are often termed "printing sleeves”.
  • the length of the cantilevered mandrel 13 will in practice be adapted to the current length of the inking or printing rolls 4 in the actual printing facility; however, in practice it is to be noted that the cleaning apparatus 2 and the transport device 24, respectively, according to the invention in principle can be operated with tubular inking or printing rolls 4 with a length of 800 - 4000 mm.
  • the indicated and described cleaning apparatus with associated transport device can be modified within the scope of the invention, as the cleaning apparatus may be adapted with a cleaning chamber with several storeys, i.e. with several superposed rotatable cantilevered mandrels for receiving inking or printing rolls.
  • the associated transport device may either be adapted with several horizontal support bearings with the desired number of inking or printing rolls arranged upon one another, or be arranged with additional vertically adjustable horizontal support bearings.
