Definitions

  • the present invention relates to cylinders for web-like material processing machines according to the preamble of claim 1.
  • Such facilities serve inter alia the tempering of the plate or pressure cylinders on the circumference, heat being able to be supplied to and removed from the cylinder surface by a circulating medium.
  • the spindle protrudes laterally from the end shields so that a bending compensation on the spindle can be achieved by means of radially acting actuators.
  • the spindle is spirally surrounded by a liquid line for cooling the oil enriched in the intermediate space, this line running in the region of the bearing journal of the cylinder in the axis of rotation of the spindle, water being used to cool the oil.
  • This heat exchange proves to be very sluggish and energy intensive. This construction also allows moderate, difficult to monitor temperature control on the circumference of the cylinder.
  • the object of the invention is therefore to provide a cylinder of the type described at the outset, which can be of uniform temperature and full-walled design on the circumference.
  • This near-surface cable routing considerably reduces the inertia of the heat transfer and noticeably improves the heat balance on the cylinder surface. At the same time, the control of the heat on the cylinder surface is simplified and the energy requirement is reduced.
  • the cylinder is further characterized by a supply line of the liquid arranged coaxially in a bearing journal, which feeds through the cylinder in the direction of the axis of rotation and opens at the cylinder end into a distribution space which is connected by the line arrangement to the collecting space arranged at the opposite end of the cylinder whose drain line is the feed line surrounds annular space.
  • This embodiment makes it possible to provide the inlet and outlet opening of the liquid line at the journal end.
  • a known supported rotating connection could be used at the inlet and outlet opening.
  • the feed line can pass through the collecting space as a tube and then be formed as a bore in the cylinder or. end in the distribution room.
  • a seal bearing against the feed line could be provided in the bore.
  • the supply line and the drain line could be functionally interchanged, in that a liquid supply line arranged in a bearing journal coaxial to the axis of rotation of the cylinder opens into a distribution space provided on the cylinder end associated with the journal, which through the line arrangement is arranged at the opposite end of the cylinder is connected to the collection line having the discharge line leaving the liquid supply direction, in such a way that the discharge line passing through the distribution space approximately in the axis of rotation of the cylinder is continued within the supply line and with it in the bearing journal to form an annular space.
  • the conditions of the previous embodiment apply approximately, the cross sections of the individual line sections being adapted to one another in the sense of an ideal flow.
  • the drain line can be designed as a bore in the cylinder and the distribution space as a pipe.
  • the cylinder can furthermore pass through a feed line arranged in a bearing journal coaxial to the axis of rotation of the cylinder, which leads into a distribution space provided at the cylinder end associated with the bearing journal, which through the line arrangement with the drain line provided at the opposite cylinder end leads into a discharge journal guided in its associated journal end having collecting space is connected.
  • the distribution and collection space are designed as end-side recesses in the cylinder.
  • the bearing pins are detachably fastened by means of a flange on the end faces of the cylinder and form part of the distribution and collection space.
  • the trunnions can be attached to an adapter immersed in the recess be attached. Due to the limited installation options due to the line arrangement and the distribution and collection spaces, the adapter provided on the front cylinder ends can prove to be a different solution, in particular if the cylinder is to have a balanced surface over its entire width.
  • the distribution and collection space can be formed with a wall that has approximately the cross-sectional shape of the channel and projects laterally into the recess. Accordingly, the adapter must also be provided with a corresponding recess on the circumference.
  • FIG. 1 to 4 show three alternative embodiments of a cylinder 1 for web-like material processing machines, in particular plate or impression cylinders of rotary printing units, not shown.
  • These cylinders 1 have bearing pins 2, 3 at their lateral ends, which are rotatably mounted in bearing plates 4, 5.
  • a liquid line 8 passes through the approximately full-walled cylinder 1 approximately in the direction of its axis of rotation 7 from an inlet opening 9 via an arrangement of a plurality of lines 11 which run approximately parallel to the axis of rotation 7 and below the cylinder surface 6, to an outlet opening 10, the lines 13 ends in distribution 11 or collection spaces 12 arranged on the end face of cylinder 1 and communicating with inlet 9 and outlet openings 10.
  • the liquid line 8 has a feed line 14 which extends coaxially in the bearing journal 2 and which initially passes through the collecting space 12 provided at the front end of the cylinder end assigned to the inlet opening 9 of the liquid line 8 and then leads as a bore 15 to the distribution space 11 is.
  • This distribution space 11 extends radially in the cylinder 1 towards the lines 13 connecting it, the cylinders 1 illustrated being provided on the circumference with a clamping and clamping device 16 for plate or other coverings, so that in this area of the cylinder circumference the adjacent lines 13 are separated from each other by an approximately larger distance.
  • both bearing journals 2, 3 are suitable for forming a section of the liquid line 8.
  • FIG. 3 shows, analogously to FIG. 1, a cylinder 1, which essentially differs in that the liquid is supplied via the line designated as the discharge line 18 in FIG. 1 or the supply line 14, which is designed to form an annular space 21 serves as drain line 18.
  • the distribution space 11 is separated from the discharge line 18 by the seal 20. Otherwise, the arrows in the liquid line 8 each point to the direction of flow.
  • Fig. 4 mediates a cylinder 1, in which the in a bearing pin 2,3 coaxial to the axis of rotation 7 of the cylinder 1 feed line 14 into one of these bearing pin 2 or. 3 or this cylinder end associated distribution space 11 opens, which through the lines 13 of the arrangement on the circumference of the cylinder 1 with the provided on the opposite cylinder end, in its associated journal 2 and. 3 guided drain line 18 of the collecting space 12 is connected.
  • the cylinder end according to FIG. 1 can be seen in more detail.
  • the collecting room 12 as well The distribution space (not visible) at the opposite cylinder end is designed as a recess 21 which is excavated from the end face of the cylinder and which can be produced, for example, by milling, eroding or, in the absence of a clamping and clamping device, by turning.
  • the space formed by the depression 21 extends at least approximately up to the periphery opened up by the lines 13.
  • the bearing journals 2, 3 are detachably fastened to the end faces of the cylinder 1 by means of flanges 22, for which purpose an adapter 23 is fastened in the recess 21, for example by welding seams.
  • This adapter 23 has - as illustrated in FIG. 6 - approximately the shape of the recess 21, a wall 25 formed by the channel 24 of the tensioning and clamping device 16 projecting laterally into the cylindrical recess 21 in the present case.
