Definitions

  • the invention relates to a winding shaft with a tensioning device for winding cores made of cardboard, in particular for receiving a washcloth of a cylinder washing device in printing machines, according to the preamble of patent claim 1.
  • a winding shaft with these training features is known from the company advertisement R 1255 from Deublin Automaticbau GmbH, 6234 Hattersheim 2.
  • the winding shaft which can be plugged through the winding sleeve, has a plurality of radially extendable tensioning elements in the tensioning area, which are designed in the form of a stamp and act either directly against the inner jacket of the winding sleeve or against radially expandable tensioning shells.
  • the radially directed clamping movement of the stamp-shaped clamping elements is carried out pneumatically, hydraulically or mechanically.
  • the torque is introduced into the winding shaft by means of a driver mounted in a frame or the like with axially directed recesses into which radially directed pins on the winding shaft engage, or by similar interlocking form-locking elements.
  • a driver mounted in a frame or the like with axially directed recesses into which radially directed pins on the winding shaft engage, or by similar interlocking form-locking elements.
  • DE-OS 37 44 105 is also known from frictional forces, non-positive clamping means for web rolls.
  • DE-OS 23 62 207 discloses a hydraulically expandable mandrel for web rolls. According to this, a hose that can be acted upon pneumatically or hydraulically with a pressure medium is spiraled between an inner one Core and outer clamping shells arranged. Expandable clamping sleeves under hydraulic internal pressure are known from DE-OS 31 16 289. Because of their high weight, these designs are also not suitable for the purpose touched by the invention.
  • the object of the invention is to improve the winding shaft with the tensioning device for winding cores made of cardboard without form-fitting entrainment elements in cylinder washing devices in printing machines with regard to their operationally reliable function for largely avoiding damage to the winding core due to excessive stress and / or drenching.
  • the invention solves this problem by training with the features of claim 1.
  • FIG. 1 shows the arrangement of a cylinder washing device for between one Plate cylinder 1 and a printing cylinder 2 arranged blanket cylinder 3 of a sheet-fed offset printing press.
  • two winding shafts 5 and 6 are mounted with axes parallel to one another and to the axis of the rubber cylinder.
  • the cylinder wash cloth 7 running from the winding shaft 5 is pressed by the pressing device 8 against the circumference of the rubber cylinder 3 and then wound up on the winding shaft 6, which is connected to the drive for the feed device.
  • both winding shafts 5 and 6 each consist of an end part 11 and 12 or 13 and 14, one or more annular clamping elements 15 and 16 or 17 and 18 and spacer sleeves 19 and 20 located between them.
  • the clamping elements 15 and 16 or 17 and 18 consist of an elastic material, but the spacer sleeves 19 and 20 are made of a solid material.
  • each winding shaft 5 or 6 The end parts 11 and 12 or 13 and 14 of each winding shaft 5 or 6 are penetrated over their entire length by a tension rod 21 or 22 which also passes through the tensioning elements 15 and 16 or 17 and 18 and the spacer sleeves 19 and 20, so that these components are supported radially inwards on the tension rod 21 or 22.
  • One end part 12 or 14 of each winding shaft 5 or 6 is mounted in a bearing 23 or 24 such that it can be rotated axially to a limited extent on the side part 4b of the frame 4.
  • the other end part 11 or 13 of each winding shaft can be connected axially with tensile strength to a bearing body 25 or 26 via a plug-in coupling.
  • the bearing body 26 is rotatably but axially fixed in a bushing 27 in the side part 4a of the housing frame 4 and connected to a drive device, not shown in the drawing.
  • the complementary parts of the plug-in couplings 29 and 30 are formed on the one hand on the bearing body 25 or 26 and on the other hand on the end part 11 or 13 and consist, for example, of one (or more) cams on one part and one (or more) corresponding recess the other part, so that the complementary parts of the plug-in couplings 29 and 30 lock together by twisting when the clamping forces are introduced into the clamping elements 15, 16 or 17, 18 and thus an axial movement of the end parts 11 or 13 and the winding tube 9 or 10 prevent.
  • the tensioning rod 21 or 22 passes through a nut 31 of the plug-in coupling 29 or 30 with a threaded pin 31, the free end of the threaded pin 31 being immersed in a free bore in the bearing body 25 or 26.
  • the tension rod 21 or 22 has an annular shoulder 32 at the transition to the threaded pin 31, which is supported against an inner annular shoulder of the end part 11 or 13 and as a limit for the axial movement of the tension rod 21 or 22 relative to the end part 11 or 13 is effective.
  • an actuating screw 33 or 34 with an annular shoulder 35 is firmly inserted in each clamping rod 21 or 22, so that a rotation of this actuating screw causes a rotation of the clamping rod 21 or 22, as a result of which the threaded pin 31 fits into the nut thread of the plug coupling 29 or 30 screwed in and due to the shortening of the clamping length between the two end parts of a winding shaft, axial clamping forces are caused by which the clamping elements 15 and 16 or 17 and 18 are pressed together so that they deform radially outwards and with their outer surface against press the inner casing of the winding tube 5 or 6 to bring about the non-positive connection of the winding shaft 5 or 6 to the winding tube 9 or 10.
  • the actuating screw is turned in the opposite direction, so that the threaded pin 31 unscrews from the plug-in coupling 29 or 30.
  • This also releases the complementary elements of the plug-in coupling so that they disengage and the tension rod 21 or 22 with the end parts 11 and 12 or 13 and 14 supported on it and the tensioning elements 15 and 16 or 17 and 18 between them.
  • the spacer sleeves 19 and 20 can be pulled out to the right through the correspondingly dimensioned bearing 23 and 24 in the side part 4b in order to enable the winding sleeve 9 and 10 to be changed.
  • a locking ring 28 is provided at the free end of the threaded pin.
  • a new winding sleeve is inserted in reverse order, in which the tensioning rod with the elements and spacing sleeves arranged thereon is inserted through the winding sleeve from the right until the corresponding elements of the plug-in coupling and the bearing body interlock.
  • a locking plate 36 is provided which covers the ends of the winding shaft 5 or 6 and by means of a screw 37 on the side part 4b is attachable.
  • a rewind lock, a retraction device for the cylinder washcloth and other training features known per se can be provided in the previous manner.
