Definitions

  • the invention relates to a turning bar arrangement for superimposing strands, which are formed by longitudinal section of a web printed in a web-fed rotary machine, in which each of the two turning bars arranged one above the other can be turned through 90 ° and has outlet openings for blown air on the side wrapped by the strand.
  • Such a turning bar arrangement is used when, for example, one strand of two strands is to be turned underneath the turning bars to form a folder and the other strand is to be placed over the straight strand running with the help of one turning bar used as an angle turning bar and the other as a parallel turning bar.
  • the invention has for its object to provide a turning bar arrangement of the type mentioned above so that, despite simple, automatically executable flipping by 90 °, the outlet openings for the blown air always lie on the side of a turning bar wrapped around the strand.
  • the functions of the turning bars are changed during a changeover such that the angle turning bar and the parallel turning bar interchange their function.
  • the arrangement according to FIGS. 1 and 2 comprises two turning bars 1, 2 which can be folded over by 90 ° and which have at one end a bar head 3, 4 provided with a fitting bore. These rod heads 3, 4 are mounted in slotted turning rod carriers 5, 6. Each dowel hole is penetrated by a dowel pin 62, 63, which is held by the turning bar support 5, 6. Each turning bar 1, 2 is rotatable about the respective dowel pin 62, 63.
  • the turning bar supports 5, 6 in turn are longitudinally displaceable on a crossbeam 7 which is mounted at both ends in the side walls 8, 9 of the turning bar structure of the printing press. Both the wall 8 on the operating side and the wall 9 on the drive side each have an operating window 10, 11 and limit the space accommodating the turning bars 1, 2.
  • Each turning bar support 5, 6 is assigned a threaded spindle 12, 13, the longitudinal axes of which run parallel to that of the crossmember 7. Outside the space delimited by the side walls 8, 9 of the printing press, a geared motor 14, 15 is associated on the drive side of each threaded spindle 12, 13 and cooperates with the respective threaded spindle 12, 13.
  • the other end of the turning bars 1, 2 is held in a slide guide 16, 17.
  • the slide guides 16, 17 are each rotatably mounted on a carrier part 18, 19.
  • the carrier parts 18, 19 in turn sit axially displaceably on a crossmember 20, 21, the axes of which run parallel, are arranged one above the other and have an axis spacing of at least two diameters of a turning bar 1, 2, so that when turning the turning bars 1, 2 can be passed therebetween are.
  • Each traverse 20, 21 is also assigned a threaded spindle 22, 23, which is connected to a geared motor 24, 25 on the drive side.
  • a flexible hose 26, 27 engages in each of these free ends of the turning bar 1, 2 and is connected to a telescopic tube 28 rotatably mounted on the wall 9.
  • the turning bars 1, 2 can be supplied with blown air, which flows out of openings (not shown) provided in the turning bars and ensures good guidance of the paper web.
  • FIGS. 1 and 2 comprises a cutting roller 29, which is arranged in parallel to the crossbeams 20, 21 in front of the turning bars 1, 2 while observing the direction of travel of the paper web through the printing press. Between the cutting roller 29 and the turning bars 1, 2, two paper guide rollers 30, 31 are also arranged one above the other parallel to the crossbeams 20, 21.
  • FIGS. 3 and 4 show that a strand 32 coming from the cutting roller 29 is guided in a straight line to the folder by means of the paper guide roller 30 under the turning bars 1, 2.
  • Another strand 33 runs tangentially to the top of the turning bar 2 used as an angle turning bar, i.e. the cutting roller 29 is positioned in the printing machine so that the top of the cutting roller 29 and the top of the upper turning bar 2 are tangentially and horizontally connected by the strand 33.
  • the turned strand is guided tangentially away from the underside of the parallel turning rod via the first strand 32 to the folder by means of the lower turning rod 1 used as the parallel turning rod 1.
  • both turning bars 1, 2 are turned through 90 °, as shown in FIGS. 5 and 6.
  • the changeover can be carried out manually by means of handwheels on the operating side 8, or automatically and preset by the geared motors 14, 15, 24, 25 assigned to the threaded spindle 12, 13, 20, 21. In the case of manual transfer, stops or markings must be made on the support spindle 7, 20, 21 for positioning.
  • the turning bars 1, 2 are automatically turned over, the respective end position can be monitored and positioned by means of a rotary encoder and can be displayed on a control panel.
  • a pair of turning bars for superimposing strands can also be formed according to FIG. 7.
  • the arrangement required for this has a cross member 34, which is fixedly arranged between the side walls of the turning bar structure of a printing press.
  • Two support elements 35, 36 which are parallel to one another are fixedly mounted on the crossmember 34.
  • a guide rail 37 is fixedly arranged parallel to the cross member 34.
  • Two holder blocks 38, 39 grip around the guide rail 37 in a jaw-like manner and are axially displaceable along this.
  • the holder blocks 38, 39 each have a shoulder 40, 41 on the side opposite the cross member 34.
  • Each threaded spindle 42, 43 passes parallel to the cross member 34 and the guide rail 37, a carrier element 35, 36 and an extension 40, 41 of a holder block 38, 39.
  • Each threaded spindle 42, 43 is rotatable but axially secured to a carrier element 35, 36 stored.
  • a plate 44 projecting beyond the side of the holder block 38 facing away from the cross member 34 is fixedly attached.
  • a pneumatic lifting cylinder 45 is mounted on the protruding part of the plate 44, the movable piston rod 46 of which is screwed to a plate 47 parallel to the lower plate.
  • a pivot axis 48 fixedly mounted on this upper plate 47 passes through a vertical bore 49 through the holder block 38 and the lower plate 44.
  • the radius of the pivot axis 48 is smaller than the radius of this hole.
  • the underside of the pivot axis 48 is fixedly attached to a torsionally rigid frame 51, in the side walls 52, 53 of which a turning bar 2 is mounted.
  • a dovetail-shaped guide part 54 which is screwed to the upper plate 47 and can pass through the lower plate 44, is guided on the side of the holder block 38 remote from the cross member 34 in a recess 54 adapted to it.
  • a geared motor 55 which is attached to the underside of the upper plate 47, cooperates with the pivot axis 48 by means of gear wheels 56, 57, which are arranged on the upper side of the upper plate 47, and enables the turning bars 2 to be turned through 90 °.
  • gear wheels 56, 57 which are arranged on the upper side of the upper plate 47, and enables the turning bars 2 to be turned through 90 °.
  • a similar arrangement is provided for folding the turning bar 1.
  • the pivot axis 48 can be done by means of a transverse bolt 60, which is driven by a short-stroke cylinder 61 and by a side wall of the holder blocks 38, 39 engages, be clamped in the bore 49.
  • each turning bar 1, 2 changes its function from angled to parallel turning bar and vice versa, and the relative difference in height of the turning bars 1, 2 to each other is reversed.
  • the height of the strand to be turned does not have to be deflected and a paper guide roller required for this can be dispensed with. Nevertheless, it is ensured that the outlet openings for the blown air are always positioned so that an air cushion is built up between the turning bar and the paper web guided over it.
  • the air supply to the turning bars 1, 2 takes place at a free end via a flexible hose 58 which is connected to a rotatably mounted telescopic tube 59.
  • the invention is not restricted to the exemplary embodiments shown. 3 to 6 could also be provided in the case of overturned turning bars. Then the height adjustment of the turning bars is not necessary.
