Definitions

  • the invention relates to a method for the automatic mounting of a printing cylinder of a printing unit having a longitudinal axis by means of a second bearing in a second holder, wherein in order to make the printing cylinder accessible, the second holder is adjusted by an axial stroke a in the extension of the longitudinal axis of the printing cylinder to expose a second bearing point or the second bearing and is adjusted perpendicular to the longitudinal axis of the printing cylinder by an adjustment path y, wherein the printing cylinder is held in a first holder.
  • the invention further relates to a method for the automatic mounting of a printing cylinder of a printing unit having a longitudinal axis by means of a second bearing mounted in a second holder, wherein, in order to make the printing cylinder accessible, the printing cylinder is adjusted by an axial stroke a in the extension of the longitudinal axis to separate the printing cylinder from the second holder and wherein the second holder is adjusted perpendicular to the longitudinal axis of the printing cylinder by an adjustment path y, wherein the printing cylinder is held by means of a first holder.
  • the invention further relates to a printing unit comprising a first holder with at least one first bearing for receiving a first bearing point of a printing cylinder with a longitudinal axis and a second holder with at least one second bearing for receiving a second bearing point of the printing cylinder, wherein in order to make the printing cylinder accessible, the printing unit is designed such that the second holder is first movable by an axial stroke a in the extension of the longitudinal axis of the printing cylinder to release the second bearing point or the second bearing and is then adjustable perpendicular to the longitudinal axis by an adjustment path y, wherein the printing cylinder is mounted in the first holder.
  • Printing units are known from the prior art in which a change of the functional surface and/or the circumference of at least one printing cylinder is possible, for example by means of printing form sleeves, sleeves for changing the transfer cylinder or sleeves of different thicknesses for changing the cylinder circumference and thus the printing length.
  • a printing cylinder can therefore be designed, for example, as a printing form cylinder, which in offset printing is also called a plate cylinder, as a transfer cylinder, which in offset printing is also called a rubber cylinder because of its cover with a printing blanket known as a rubber blanket, or as a counter-pressure cylinder. If such sleeve-shaped sleeves have to be replaced, this is only possible by sliding the sleeve sideways onto the corresponding printing cylinder due to the sleeve being closed in the circumferential direction.
  • the EP 2 388 141 A2 a format-variable printing unit in which a plurality of printing cylinders are arranged in a spatially variable manner in order to be able to exchange or change the corresponding printing cylinders.
  • the DE 199 37 796 A1 discloses a printing unit concept in which the printing cylinders are mounted in linear guides so that they can be adjusted relative to one another, so that if the cylinder diameter changes, the distance between the cylinders can be adjusted.
  • a printing cylinder is supported on both sides, i.e. on both sides of the functional surface.
  • a printing cylinder comprises on its first side a first bearing point on the cylinder, on which a first bearing, usually a roller bearing, is arranged, wherein the first bearing is arranged in a first holder.
  • the first holder can be the side wall, for example, if the spatial position of the printing cylinder is not to be changed or only slightly changed, whereas in spatially adjustable printing cylinders the first holder is arranged so that it is spatially adjustable relative to the side wall.
  • Such a printing cylinder further comprises a second bearing point on its second side, on which a second bearing, which is usually also designed as a roller bearing, is mounted. This second bearing is mounted in a second holder.
  • the second holder In order to replace the cover or a closed sleeve on the printing cylinder, the second holder must be removed in front of the printing cylinder in the direction of the longitudinal axis of the printing cylinder. To do this, for example, the second holder is pulled from the second bearing in the longitudinal direction of the printing cylinder, or the second holder is pulled together with the second bearing from the second bearing point of the printing cylinder and then moved in a plane perpendicular to the longitudinal axis of the printing cylinder so that the printing cylinder is accessible in the direction of its longitudinal axis, making it possible to convert the printing cylinder. While the first holder is removed from the printing cylinder, the printing cylinder is held exclusively in the second holder. It is also possible for additional support to be provided on a pin on the printing cylinder in addition to the first holder.
  • the printing cylinder After the conversion process, such as changing a sleeve on the printing cylinder, the printing cylinder must be stored in the second holder again, whereby the second holder, if necessary with the second bearing installed in it, is moved to the original position so that the second holder is then either pushed in the direction of the longitudinal axis of the printing cylinder onto the second bearing of the printing cylinder, or the second bearing mounted in the second holder together with the second holder is pushed in the direction of the Longitudinal axis of the printing cylinder is pushed onto the second bearing point of the printing cylinder.
  • the present object is solved by a method according to claims 1 or 7 and by a device according to claim 13.
  • the object is achieved by a method in which, in order to re-accommodate the printing cylinder by the second holder, in a first method step the second holder is adjusted by a first partial adjustment path y1 perpendicular to the longitudinal axis of the printing cylinder, wherein the first partial adjustment path y1 deviates from the original adjustment path y, wherein in a second method step the second holder is adjusted by a first partial axial stroke a1 in the extension of the longitudinal axis of the printing cylinder, so that the second holder partially grasps the second bearing or that the second bearing located in the second holder partially grasps the second bearing point of the printing cylinder, wherein in a third In a first method step, the second holder is adjusted by a second partial adjustment path y2 perpendicular to the longitudinal axis of the printing cylinder, wherein in a fourth method step the second holder is adjusted by a second partial axial stroke a2 in the extension of the longitudinal axis of the printing cylinder, so that the
  • the task is solved by a method in which, in order to accommodate the printing cylinder by the second holder, in a first method step, the second holder is adjusted by a first partial adjustment path y1 perpendicular to the longitudinal axis of the printing cylinder, wherein the first partial adjustment path y1 deviates from the adjustment path y, wherein in a second method step the printing cylinder is adjusted by a first partial axial stroke a1 in the extension of the longitudinal axis of the printing cylinder, so that the second holder partially grips the second bearing or that the second bearing partially grips a second bearing point of the printing cylinder, wherein in a third method step the second holder is adjusted by a second partial adjustment path y2 perpendicular to the longitudinal axis of the printing cylinder, wherein in a fourth method step the printing cylinder is adjusted

  • the diameters of the upper printing cylinder 2 and the middle printing cylinder 2 would be changed by swapping the sleeves 6 attached to the corresponding printing cylinders 2. Due to the closed surface of such sleeves 6, these sleeves 6 can only be pulled off the front of a corresponding printing cylinder 2. Due to the variable diameters of such printing cylinders 2, either these printing cylinders 2 with variable diameters and/or the adjacent printing cylinders 2 are mounted in a correspondingly adjustable manner. This can be done, for example, by the relevant printing cylinder(s) 2 being adjustably mounted in or on levers 5.
