Definitions

  • the invention relates to a blast-air-actuated turning bar for deflecting pressure carrier webs, consisting of an outer tube provided with air outlet openings and a device for covering air outlet openings not covered by the pressure carrier web.
  • the object of the invention is to show a device with which air outlet openings which are not required can be closed individually from the inside of the turning bar.
  • FIG. 1 two ends of a turning bar 5, 6, which is conventionally mounted between two machine side walls 1, 2 on a crossbar 3 and can be displaced by a threaded spindle 4, are shown.
  • These turning bars 5, 6 have a number of air outlet openings 7, 8, 9, which are usually in the area of the incoming and outgoing paper web, ie. H. about 180 ° to each other, are arranged in rows.
  • Fig. 2 shows a partial section through the turning bar 6, on which the device according to the invention for optionally closing and releasing air outlet openings 7, 8, 9 is explained below.
  • the turning bar 6 shown in FIGS. 1 and 2 consists of an outer tube 11 into which a number of tube pieces 12 are inserted.
  • the length of this Rohrstieree 12 is slightly 9 are igfbbar greater than the distance of two adjacent air outlet openings 9 in a row of holes, so that a piece of pipe 12 are each outlet openings of two adjacent axial air coverable or for R.
  • each of these tube pieces has 12 depressions or recesses 10.
  • Fig.2 shows that for reasons of thermal expansion a small distance is provided between two adjacent pipe sections 12, the sealing and positional stability of the system are still guaranteed by the formation of the ends of the pipe sections 12.
  • the pipe sections 12 have openings or slots 13 running in the circumferential direction, which can be adjusted by rotating the inner pipe sections 12 to the air outlet openings 7, 8, 9 so that some or all of these air outlet openings 7, 8, 9 are opened or closed. It is known that compressed air (for example axially) is supplied to such, so-called air-swept turning bars, which can flow out of the air outlet openings mentioned for better guidance of the pressure carrier to be deflected. Due to the circumferential displacement of the slots 13 in the inner pipe sections 12, a further influence on the air outlet openings 7 to 9 to be covered can be achieved.
  • Breakthroughs or openings 14 according to the invention in the jacket of the outer tube 11 for each of the tube pieces 12 make it possible in a simple manner that the inner tube pieces 12 can be rotated in the circumferential direction.
  • the inner tube pieces 12 have depressions 10 extending in the circumferential direction, which are provided on one side with a toothing 15 into which a cone 16, also provided with a toothing, is provided intervenes.
  • the cone 16 is connected to a control knob 17 passing through the opening 14 of the outer tube 11, so that when the control knob 17 is turned manually or with the aid of a suitable, remote-controlled steep motor or by means of flexible shafts, a rotation of the inner tube section 12 from a control station it is possible from the outside in such a way that holes or rows of holes that are not required can optionally be closed or released.
  • conventional limiting means provided in one of the holes e.g. 7
  • a clamping sleeve it is possible to provide a limit for the rotation of the inner tube pieces 12, which facilitates the individual display by means of conventional measuring means of the respective circumferential position of the inner tube pieces 12.
  • the use of an adapter sleeve has the advantage that the air hole in which it is used is not closed.
  • a further essential advantage of the exemplary embodiment according to FIGS. 1 and 2 is the use of a guide sleeve 18 which, for example, in the opening 14 of the outer tube res 12 can be glued.
  • the guide sleeve 18 has a lower projection 19 which engages in the recess 10 of the inner tube piece 12, in such a way that the toothed cone 16 engages in the side toothing 15 and at the same time the inner tube piece 12 against axial displacement is fixed.
  • a projection 19 on the guide sleeve 18 is used.
  • a catch 20 with a ball 21 can be used on the adjusting knobs 17. A defined setting of the circumferential position of the inner tube pieces 12 is thereby possible.
  • FIG. 4 shows the left end of a conventional turning bar 22, which consists of an outer tube 23.
  • a number of adjacent pipe sections 24 are in turn arranged in the outer pipe 23.
  • the outer tube 23 has outlet openings 25 in several rows of holes.
  • a grid e.g. B. a sheet metal catch to use to clearly fix the pipe pieces.
  • An opening or opening 26 is assigned to each tube piece 24 in the outer tube 23. This can be done manually, e.g. B. by means of the index finger, the inner tube 24 are rotated radially, so that the openings or slots provided in this release or cover the desired air outlet holes 25 in the outer tube 23. To facilitate adjustment, the inner tube pieces 24 are corrugated at the rotating areas below the openings 26.
  • the turning bar 28 in turn consists of an outer tube 30 provided with air outlet openings 29.
  • a number of inner tube pieces 32 lie side by side in the outer tube 30.
  • a recess 31 in the outer tube 30 is assigned to each tube piece 32.
  • Parallel to the outer tube 30, a holder 33 is shown, which is used for guiding or mounting adjusting wheels 34.
  • Each inner tube 32 is associated with a setting wheel 34, which is connected through the recess 31 through or at least frictionally in such a way to a pipe section 32 that by rotating the setting wheels 34 the associated inner pipe section 32 is rotated to certain air outlet holes 29 to release or lock.
  • FIGS. 1 to 5 can also be expanded in such a way that the setting means can be designed to be remotely operated with the aid of, for example, servomotors or flexible shafts.
