Definitions

  • the invention relates to a steam-heated roller, in particular for corrugated cardboard machines, with those specified in the preamble of claim 1 Features.
  • a steam-heated roller in particular for corrugated cardboard machines, with those specified in the preamble of claim 1 Features.
  • Such a roller is known from US-A-5 533 569.
  • Such steam-heated rollers can be used for a wide variety of purposes be used for the processing of web goods.
  • preheating rollers or so-called "corrugated rollers" for corrugated cardboard machines to call With such corrugated rollers, a paper web is used by working together with a counter corrugating roller in the typical Brought wave form, as can be observed with corrugated cardboard material.
  • the corrugating roller is known to support the corrugation of the paper web heated in temperature ranges from 180 ° to 200 ° C. this happens with saturated steam, which is in the interior of the hollow cylindrical roller body is introduced. Support the preheating rollers also mentioned the paper heating in front of the corrugating roller.
  • the invention has for its object the mountability of the siphon tube, improve its adjustability and pressure-tight implementation.
  • the object is achieved by that the siphon tube from an outer, rigid support tube and one inside there is a slidably mounted, flexible insert tube. Through a relative shift The distance of the suction opening is from insert tube to support tube adjustable to the roller base.
  • outer support tube installed in a certain, uncritical mounting position can be.
  • the adjustment can be carried out by means of the flexible insert tube take place, the z. B. up to the stop pushed onto the roller base and then a short distance - Just the desired distance between the suction opening and Roller base - can be withdrawn.
  • the support tube remains firm in its position, with which a particularly tight implementation by the rotatable bearing pin can be achieved.
  • Preferred embodiments of the insert tube see its design as a corrugated metal hose. This material is for use well suited under saturated steam conditions, but shows the necessary ones Flexibility in the bending direction and immutability in length in the longitudinal direction.
  • the adjustability of the suction opening is further improved in that the insert tube at its inner end with a telescopic telescope in the support tube sliding nozzle is provided as another preferred Embodiment provides.
  • the end of the support tube can be a corresponding one Have bevels so that the suction opening to the position angle the longitudinal axis at the end of the support tube is adapted. Thereby the suction opening can be adjusted so that all around uniform minimum distance is adjustable. Otherwise, the maximum angle limits the longitudinal axis of the support tube at its end the bending radius of the Support tube, because of the feasibility of a corresponding Opening in the bearing journal must not become too small.
  • a preheating roller as in a Corrugated cardboard machine is used, a roll body 1 with a roll shell 2 and on the front openings welded roller flanges 3 on.
  • the roller flanges 3 with journals 4 are central provided in a roller frame 5 with roller bearings for rotatable storage of the roller body 2 sit.
  • the roller interior 6 is not in with saturated steam for heating the roller body 1 applied.
  • the steam is e.g. B. introduced through the journal 4, why the outside of the siphon tube 8 to be explained Annulus is used.
  • the aforementioned siphon tube 8 is provided, which is pressure-tight by the Journal 4 inserted into the roller interior 6 and through his slightly curved course (see Fig. 1) ends just before the roller base 7.
  • the siphon tube 8 consists of a outer, rigid support tube 9, in which a flexible metal corrugated hose 10 is slidably mounted.
  • This corrugated hose 10 ends before the opening of the support tube 9 and is provided at its end with a nozzle 11, which is telescopically displaceable in the support tube 9.
  • the support tube 9 ends with a distance A of a few centimeters above the roller base 7 and is therefore uncritical in its assembly and adjustment.
  • the gap to Roll base 7 is bridged by the nozzle 11, the opening on free end forms the suction opening 12 of the siphon tube arrangement 8.
  • the support tube 9 is arcuate in this way trained that its longitudinal axis 13 at its roller inner end occupies an acute angle 14 of almost 60 ° to the roller base 7.
  • the suction opening 12 is in one of these Angle 14 corresponding manner beveled, so that from the front edge 15 of the nozzle 11 spanned plane parallel to that for this Purpose as the roller base to be considered essentially flat.
  • the course of the bending of the support tube 9 is dimensioned so that the Support tube 9 through the through opening provided centrally in the journal 4 16 can be threaded through.
  • the latter is, as can be seen from FIGS. 3, 5 and 6, via lateral extensions 25 held on two rods 26, 27, which are not shown in detail are rigidly connected to the roller frame 5.
  • the extensions 25 are with Passages 28 provided in which sockets for receiving the two rods 26, 27 sit.
  • Via appropriate fixing screws 30 in the extensions 25 sit and apply the rods 26, 27 via the bushings 29, the sealing head 21 can be fixed stationary in a certain position in which the connecting sleeve 22 the sealing contact to the sealing flange 18 manufactures.
  • the two ends of the rods 26, 27 are over one Yoke 51 connected to one another by nuts 52 on rods 26, 27 is fixed.
  • FIG. 3 the outer end 31 of the support tube 9 is now in one Mounting flange 32 welded position recognizable. This mounting flange 32 is via mounting screws 33 with an insert 34 in the sealing head 21 connected. This insert 34 holds the support tube 9 over a certain Length to provide adequate support.
  • the mounting flange 32 has a receptacle 35 on its outside a stuffing box 36, which can be acted upon by a clamping ring 37 is.
  • the bushing is 38 provided with an adjusting device 42, by means of which the Bushing 38 and therefore the corrugated hose 10 and the nozzle 11 are displaceable in the longitudinal direction relative to the support tube 9.
  • This adjustment device 42 sees two diametrically protruding from the bushing 38 Arms 43 in front, each with a passage opening 44 for threaded bolts 45 are provided. The latter are opposite on the clamping ring 37 the threaded bolt 41 fixed positions. On the threaded bolt 45 sit on both sides of the arms 43 fixing nuts 46 so that the in Fig. 4 shown position of the bushing 38 is fixed. Should now brought the suction opening 12 closer to the roller base 7 only the inner fixing nuts 46 (on the right in FIG.
  • an indexing device 47 in the form of an index pin 48 seated on the mounting flange 32 intended. This engages in a receiving opening 49 on the clamping ring 37 a, so that the corrugated hose 10 is never rotated in a 180 ° Location can be installed.
