Definitions

  • the above invention relates to an adjustable receiving carriage for a printing cylinder.
  • printing cylinders are used in rotary printing presses which are moved into the printing unit of the rotary printing press using suitable receiving carriages which are arranged displaceably on tracks.
  • the top of the known receiving carriages for printing cylinders has a U-shaped configuration and at the upper ends of the parallel arms of the U-shaped devices, bearings are provided for receiving the end journals of the printing cylinder.
  • One of the end journals of the impression cylinder is equipped with a drive means, e.g. B. a gear that can be connected to a corresponding drive wheel of the main drive of the printing press.
  • the known pick-up carriages have proven to be quite suitable for a long time, since their use enables the printing cylinder to be exchanged quickly in the rotary printing press.
  • extension sleeves are mounted on the pins of the shorter printing cylinders, this entails a considerable amount of mechanical engineering work, especially when one takes into account that the printing cylinders have to rotate with the highest precision. It follows that the extension sleeves have to be machined extremely precisely and this machining represents a considerable cost factor. It must be taken into account here that several different length extension sleeves are available for all printing cylinders due to their different length dimensions.
  • the known device is designed as a complete, independent printing unit, which is retracted into the printing press during operation and remains in the press, it is not suitable for replaceable printing cylinders of different lengths, using a simple pick-up carriage and with provision for displaceable bearings in retract or remove the press for assembly purposes.
  • the object of the above invention is to provide a new receiving carriage for a printing cylinder of the type described, which is used in a rotary printing press and which enables printing cylinders of different lengths to be used without the need to equip the printing cylinder with extension and receiving sleeves . It should also be possible to quickly replace the printing cylinders without great assembly effort and to store the printing cylinders directly, regardless of their length.
  • slide guides 9 are provided parallel to the longitudinal axis of the printing cylinder 16, and carry sliding devices 10, 11 thereon for the mounting 12-15 of the end journals 17, 18 of the printing cylinder 16.
  • the end journals of the printing cylinders receive an extension sleeve, which is provided only for receiving connecting means, but does not have a storage and support function, but only for adjusting and positioning the printing cylinder inside the machine, and for connecting the cylinder to one Drive device, which is part of the central drive system of the machine, is provided.
  • the carriage identified as a whole by 1, consists of a frame 2 which is supported by wheels 3 and 4 Tracks 5 is movable, which are aligned perpendicular to the side car 6 and 7 of the machine.
  • Tracks 5 is movable, which are aligned perpendicular to the side car 6 and 7 of the machine.
  • the cheek 7 has a recess for the insertion of the carriage 1 into the machine, whereas the opposite cheek 6 of the printing machine has an opening 8 for the passage of the extended connecting piece 19, which will be described in more detail below.
  • the carriage 1 On its upper side, the carriage 1 has parallel sliding guides 9, such as these e.g. are known from machine tool manufacturing. These sliding guides slidably receive receiving devices 10 and 11 which can be moved in the direction of arrow f along the parallel sliding guides 9. Each receiving device 10, 11 receives a known bearing block 12 or 13, which receives a ball bearing 14 or 15.
  • Each pressure cylinder 16 has an end pin 17 or 18, the extension 17a or 18a of which is received by the race 14 or 15 of the ball bearing.
  • Each extension 17a or 18a also has a further pin-like extension 17b or 18b which receives an extension sleeve 19 or 20 which is fixedly connected to the pin 17b, 18b.
  • a screw 21 or 22 is used for this purpose.
  • the extensions 19 and 20 do not have any storage and support functions and are described in more detail below.
  • the bearing blocks 12 and 13, together with the receiving devices 10 and 11 can be moved along the slide guides 9 in the direction of arrow f and thus allow adaptation to the changing length I of the printing cylinder 16, as well as any positioning of the printing cylinder 16 on the Carriage 1 and thus in the printing press.
  • the bearing blocks 12 and 13 can have an extension bracket 23 and 24, which is indicated schematically by broken lines and points downward. Each downward extension bracket 23, 24 is operatively connected to a threaded spindle 25 or 26, each of which can be driven in the direction of arrow g.
  • each threaded spindle 25 or 26 is operatively connected in a known manner, not shown, to a handwheel, via which the receiving devices 10 and 11 and the bearing blocks 12 and 13 are displaced when the rotary movement occurs.
  • These components can thus be positioned in the desired position along the parallel sliding guides 9.
  • each receiving device can be fixed on the slide guides 9, z. B. using clamping screws or similar tools, such as clamping claws.
  • both the extension 17b of the end pin 17 and the extension 18b of the end pin 18 of the pressure cylinder 16 are equipped with extension sleeves 19 and 20.
  • the extension sleeves 19 and 20 have no support or bearing function.
  • the extension 19 shown on the left side of the drawing receives at its end a gear 27 which e.g. is brought into operative connection with a further gear wheel 28.
  • the gear 28 is driven by the central drive system of the printing press and thus sets the printing cylinder 16 in rotary motion.
  • the extension 19 is fixed to the extension 17b of the end pin 17, e.g. connected with the aid of a continuous clamping screw 21 and a connecting wedge 29 is inserted between the extension piece 17b of the end pin 17 and the end of the extension sleeve 19.
  • the extension 18b of the end pin 18 is also connected to a non-load-bearing extension sleeve 20 and also in this case a screw and a wedge 30 are used for the fixed connection to the end pin 18.
  • the free end of the extension sleeve 20 is operatively connected to a rotating device 31.
  • This rotating device 31 has the task of positioning the printing cylinder 16 in its angular position in order to ensure that all printing cylinders are perfectly aligned with one another over the entire length of the printing press (register).
  • the pressure cylinder 16 is mounted in the immediate vicinity of its end journals, and thus the resulting bending moment is considerably smaller than in the case of the previously known receiving and storage devices which were previously provided on the ends of the known receiving carriages. According to the above invention, the pressure cylinder 16 can be moved and positioned as desired on the slide guides 9 of the carriage 1 and the exchange of a pressure cylinder 16 with a pressure cylinder which has other length dimensions I takes place quickly and without the need to carry out complex and time-consuming assembly work.
  • extension sleeve 19 and 20 requires considerably less effort, since these components have no bearing function to fulfill, but are only provided for the transmission of the rotary movement to the pressure cylinder 16 and for the transverse adjustment.
