Definitions

  • the invention relates to a feed device for web-fed rotary printing presses for pulling material webs with a feed element made of flexible solid material, which is displaceable along the tubular guide along the feed path for the material web.
  • a device for pulling material webs in rotary printing presses in which along different lateral feed paths, which are formed by guides and switches located outside the roller area, either a feed element made of flexible solid material of finite length extension in the form of a flat one , continuous steel belt or a multi-link roller chain in the guides along the set feed path is displaceable. Due to the shape or design of these feed elements, a bend, apart from a certain twisting possibility, is only possible in one plane perpendicular to the longitudinal extension, so that complicated feed paths, such as. B. by the turning bar structure, this can not be practically realized.
  • the object of the invention is to develop the known feed device for web-fed rotary printing presses of the type defined at the outset in such a way that even very complicated, i.e. H. heavily twisted feed paths can be realized.
  • the pull-in element has a round or polygonal solid cross-section, so that the bending resistance is approximately the same in all directions transverse to the longitudinal axis of the pull-in element.
  • the guides according to the invention can select the guides for the pull-in element to determine the feed path individually and without directional restrictions in accordance with the available spatial conditions of a printing press.
  • Fig. 1 shows a known web offset printing press, in which the varied and sometimes extremely complicated web guides are shown.
  • the paper webs 9, 10, 11, 12 printed in printing units 1, 2, 3 and 4, fed by roller stars 5, 6, 7, 8, are fed via guide and turning bars (not further specified) after a corresponding longitudinal division of a folding device 13, in which the The printed sheets 9 to 12 are cut and folded.
  • the paper webs 9 to 12 are drawn in between certain cylinders of the printing units 1 to 4, which are not described in any more detail.
  • 1 shown printing machine does not represent printing and dampening units and other necessary facilities. 1 is intended to illustrate the varied and complicated nature of the paper web guides in modern printing presses, the scope of which often exceeds a multiple of the machine shown in FIG. 1.
  • the pulling cable 14 shown in FIGS. 2 and 3 serves as the pull-in element.
  • a pull-in element with a polygonal cross-section can also be used. It is essential that the pull-in element is bendable on all sides so that the possible pull-in paths are not restricted by the shape of the pull-in element.
  • the pull cable 14 is guided in a guide tube 15 which is laid in the printing press in accordance with the desired feed paths.
  • the traction cable 14 has a drag hook 16 which protrudes through slots 17 provided in the guide tubes 15 and to which the paper web to be drawn in can optionally be attached via a cable.
  • At least one pair of friction wheels 20, 21 acts on interruptions between different guide tubes 15.
  • At least one wheel, here the wheel 21, consists of a role, for. B. from Hard rubber, which is pressed by a compression spring 22 against the pull cable 14. This ensures reliable guidance of the traction cable 14, wherein synchronization between several pairs of friction wheels is not necessary due to the possibility of slipping.
  • the guide tubes 15 are fixed to a machine side wall 19 or to another frame-fixed holder in the printing press by means of conventional fastening tabs 18.
  • FIG. 4 shows, in a further development of the invention, a switch 23 with the aid of which the pull-in element guided in a guide tube 24 can optionally be introduced into a guide tube 25 or a guide tube 26.
  • Fig. 5 shows an expanded option.
  • the switch 30 shown here offers the pull-in element arriving in the guide tube 31 three ways, namely the guide tube 32, the guide tube 33 or the guide tube 34.
  • the paths are selected by setting a turntable 35, which can be brought into three positions by a double-acting pneumatic cylinder 36.
  • the pull-in element is guided in a straight line from the guide tube 31 to the guide tube 33.
  • the pneumatic cylinder 36 In the left position of the pneumatic cylinder 36 there is a forwarding to the guide tube 32 and in the right position to the guide tube 34.
  • the two-part pneumatic cylinder 36 which is divided by an intermediate piece 37, can be rotated about a pivot pin 38 to compensate for the length difference.
  • FIGS. 10 and 10 schematically show front and side views of a drive device for the pull cable 14.
  • the guide cable 14, which is exposed between guide tubes 43 and 44 is driven in the longitudinal direction between friction wheels 48, 49, which can be driven by gear wheels 45, 46 and 47, and a friction wheel 50 , d. H. pushed.
  • the traction cable 14 is guided through part of the circumference of the friction wheel 50 by the friction wheels 48, 49, as a result of which the friction and thus the feed effect with respect to tangential cable guidance is significantly improved.
  • Appropriate recesses - preferably with a semicircular cross-section - on the circumference of the friction wheels 48, 49, 50 for the traction cable guide provide an additional improvement.
  • the gears 45, 46, 47 are driven by a motor 51.
  • 11 and 12 show a second drive device in which the section of the pulling cable 14 running between guide tubes 52, 53 can be driven by pairs of friction wheels 54, 56 and 55, 57. These are set in rotation by means of a motor 58 via gear wheels 59, 60, 61, 62 and 63.
  • FIGS. 13 and 14 A particularly effective drive device is shown in FIGS. 13 and 14, with which a high thrust torque can be transmitted to the pull rope.
  • the Z. B. emerging from a guide tube 64 and entering a guide tube 65 guide rope 14 is guided around a friction wheel 71, on the periphery of which two friction wheels 70, 72 are arranged.
  • the friction wheels 70, 71, 72 can be driven by a motor 69 via gear wheels 66, 67, 68.
  • a guide device 73 in the form of a guide jacket is provided around the friction wheel 71.
