Definitions

  • the invention relates to a tension roller and a machine for producing a corrugated cardboard web laminated at least on one side according to claims 1 and 7, as shown in EP-A-0687552 is known.
  • the pressing device on a usually woven, sieve-like pressure belt.
  • the tension roller is cylindrical in the usual way and completely rigid in itself, then occurs after a relatively short operating time of the band, at least before the normal wear of the pressure belt, a low elongation in the central region of the pressure belt, which leads to a reduction of the contact pressure of the pressure belt leads to the central region of the corrugated cardboard to be produced.
  • the consequence is that the gluing between laminating web and corrugated paper web may not be sufficient, which leads to corresponding quality defects of the corrugated web.
  • the tension rollers have also already been performed crowned, which is to be understood by a slight decrease in diameter from the center of the roller to its axial outer ends. However, this has not led to the desired improvement.
  • a roller of a core and a surrounding outer sheath is known, wherein the core and the outer sheath are interconnected only in the region of their longitudinal center and are separated from each other by an annular space to their outer ends.
  • the invention is therefore the object of a machine of the generic type in such a way that the tension in the pressure belt is maintained over its full width during the operating time.
  • the outer shell of the tension roller can bend slightly towards the outer ends in operation under the tension of the Anpressbandes radially in the direction of the axis.
  • this does not lead to different peripheral speeds on the surface of the tensioning roller over its full axial length, since the circumference of the tensioning roller, unlike a crowned configuration, remains unchanged over the length of the tensioning roller, even during the deflection.
  • the tensile force exerted on the pressure belt is constant over the width of the pressure belt, so that there is no greater expansion of the pressure belt in its middle region compared to the outer side regions. So there is no increased wear in the middle of the Anpressbandes.
  • the quality of the corrugated web is thus constant over the entire extended service life of the pressure belt over the full width.
  • the claims 2 to 4 give advantageous embodiments again.
  • the claims 5 and 6 give a possibility again to adjust the deflection of the tension roller.
  • the claim 7 defines the machine for the production of corrugated board.
  • a lower corrugating roll 2 and an upper corrugating roll 3 are rotatably supported by shafts 4, 5. They have mutually parallel axes 6, 7. At their cylindrical surfaces they are provided with parallel to the axes 6, 7 extending corrugations 8, 9, which mesh with each other in the contact region 10 of the two corrugating rolls 2, 3.
  • One of the corrugating rolls 2, 3, usually the upper corrugating roll 3, is driven in the direction of rotation 11, while the other corrugating roll, usually the lower corrugating roll 2, is taken along by the other corrugating roll 3 in the direction of rotation 12.
  • a glue application device 13 is arranged in the machine frame 1, which has a glue applicator roll 14, which is deliverable against the corrugation 9 of the upper corrugating roll 3.
  • the applicator roll 14 is rotatable about an axis 15.
  • a pressing device 16 which has a cylindrical, rigid deflection roll 17, a tensioning roll 18 and a pressing belt 19.
  • the guide roller 17 is freely rotatably supported by bearings 20 in bearings 21 of the machine frame 1 about an axis 22, so it is not driven.
  • the tensioning roller 18 is mounted by means of bearing journals 23 about its axis 24 in bearing levers 25, which in turn are mounted pivotably in bearings 26 mounted in the machine frame 1.
  • a clamping drive 27 which is a hydraulically actuated piston-cylinder drive.
  • This tensioning drive 27 is in turn pivotally mounted in an abutment 28 which is mounted on the machine frame 1.
  • a tensioning of the pressure belt 19 thus takes place by pivoting the tension roller 18 approximately parallel to the outlet tangent 29 in the direction 30. All axes 6, 7, 15, 22, 24 are parallel to each other.
  • Fig. 1 As Fig. 1 can be removed, is the pressure belt 19 over a wrap angle ⁇ of about 90 ° against the corrugation 9 of the upper corrugating roll 3 and runs in the same direction with this direction of the arrow 31.
  • the pressure belt 19 runs from the upper corrugating roller 3 according to the spatialtangente 29, which is identical to the inlet tangent of the Anpressbandes 19 on the tensioning roller 18.
  • the pressure belt 19 is formed as a fine mesh, tensile sieve, as it is for example from the DE 10 2005 035 030 A is known.
  • the tension roller 18 is hollow. It has a tubular core 32 and a likewise cylindrical outer casing 33.
  • the outer jacket 33 and the core 32 are integrally formed; they are only in the longitudinal center still on a ring land 34 interconnected.
  • an annular space 35 or 35 ' is formed, which is for example stabbed.
  • the bearing journals 23 are fastened by means of screws 36 to the end faces of the core 32.
  • the outer sheath 33 is thus only centrally connected via the annular web 34 with the core 32 and thus with the bearing pin 23.
  • an abutment for deflections of the outer jacket 33 relative to the core 32 is formed by the adjusting ring 38 as it were.
  • the adjusting ring 38 has in the 4 and 5 shown adjusting screws 42, via which it is supported against the respective flange 37 of the bearing pin 23.
  • the abutment surface 39 is displaced in the direction of the axis 24, whereby the radial width a of the gap 41 can be changed. Since the screws 36 also pass through the adjusting ring 38, the respective adjusting ring 38 is also fixedly connected in the axial direction with the core 32 and the jacket 33 and the bearing pin 23.
  • the upper corrugating roll 3 is heated in a conventional manner, for example to about 170 ° C., the water contained in the corrugation 44 at the points 45 of the corrugation 44 evaporates and escapes at least in part through the laminating sheet 46 and the sieve-like pressure belt 19.
  • the finished glued, laminated on one side with a liner 46 corrugated board 50 runs in the direction of the Spartangente 29 together with the Anpressband 19 from the upper corrugating roll 3 and is performed with the Anpressband 19 partially around the tension roller 18 around. From there, it is fed in stripping direction 51 of a take-up device.
  • the pressure belt 19 is therefore subjected over its full width with constant tensile stresses, so it does not - as usual in practice - loses strength in the middle with the result that the contact pressure or the contact pressure on the corrugated cardboard in the contact area 48 decreases with the Consequence that in the central region, the glueing between the laminating sheet 46 and the tips 45 of the corrugation 44 of the paper web 43 rises again. Due to the abutment formed by the respective adjusting ring 38, the deflection of the outer jacket 33 can be limited; By appropriate selection or adjustment of the adjusting ring 38, the deflection can thus be set and limited.
