Definitions

  • the invention relates to a machine according to the preamble of claim 1.
  • Such from the DE 42 28 074 A1 known machine has a split machine frame, wherein in a subframe the corrugating roller and in the other subframe gluing unit is attached to the glue applicator roll. Between the two racks, a device for adjusting a gap between the corrugating roll and the glue applicator roll is provided, which consists of a mounted on a subframe motorized adjusting spindle and provided on the other subframe stop against which the spindle comes to rest.
  • the adjusting spindle bearing subframe is slidably mounted and is pressed by means of a hydraulic piston-cylinder unit to the other subframe out.
  • a spacer is provided between the subframes, which ensures a minimum safety distance between the corrugating roll and the glue applicator roll.
  • This spacer is made of a material with at least extremely low coefficients of thermal expansion, for example made of carbon fiber. This known embodiment is at least very expensive.
  • a glue application roller can be acted upon by pressing means in the direction of the corrugating roller, by means of which the glue application roller is pressed with a predetermined contact pressure against the paper web located on the corrugating roller to allow a uniform gluing of the tips of the corrugations of the paper web.
  • the glue applicator roller rings are attached, the protrude only slightly above the surface of the glue applicator roll.
  • the glue application roller In order to calibrate the gluing gap to be formed between corrugating roller and glue application roller, the glue application roller is pressed against the corrugating roller by means of the pressing devices, the abutment rings abutting against the corrugation. Subsequently, the glue application roller is moved away again by a predetermined amount of the corrugating roller. Alternatively, the thrust rings can be omitted. For calibration, in this case the glue application roller is delivered directly against the corrugating roller. In practice, it has been found that when a web of paper breaks, the glue applicator roll can impinge on the corrugating roll, which can damage the surface of the corrugation.
  • the invention has for its object to design a machine of the generic type so that damage to the corrugation of the corrugating roll is prevented by impact of the glue application roller in a paper tear or the like with simple means.
  • the essence of the invention is that when there is no paper web between the glue applicator roll and the corrugating roll, an impact of the glue applicator roll on the corrugation of the corrugating roll is avoided without the spacers having any shape with the corrugation of the corrugating roll or the surface of the glue applicator roll Contact can come.
  • the spacer or spacers are not in function, that is, they are not in engagement with each other.
  • the cleaning scrapers ensure the operating unit of the spacers.
  • the safety gap is smaller than the thinnest paper web occurring in practice.
  • a thickness range results from claim 2.
  • the embodiment according to claim 6 ensures that a uniformly symmetrical guidance is always ensured.
  • Claim 7 is a known pressing device again, which may be the cause of an impact of the glue roller on the corrugation of the corrugating roller at a crack of the paper web.
  • a machine frame 1 of a machine for producing a single-faced corrugated cardboard web has two mutually parallel side walls 2, 3, in which a lower corrugating roll 4 and an upper corrugating roll 5 are mounted. How out Fig. 2 only emerges for the upper corrugating roller 5, these are mounted on shaft journals 6 in bearings 7, which are supported in the side walls 2 and 3 respectively.
  • the corrugating rolls 4, 5 have mutually parallel axes 8, 9. At their cylinder surfaces are the corrugating rollers 4, 5 with parallel to the axes 8, 9 extending corrugations 10, 11 which mesh with each other in the contact area 12 of the two corrugating rolls 4, 5.
  • One of the corrugating rolls 4, 5, usually the upper corrugating roll 5, is drivable in the direction of rotation 13, while the other corrugating roll, usually the lower corrugating roll 4, is taken along by the other corrugating roll 5 in the direction of rotation 14.
  • a glue application device 15 Downstream of the contact region 12 in the direction of rotation 13 or 14, a glue application device 15 is arranged in the machine frame 1, which has a glue container 16 held in the machine frame 1.
  • a glue applicator roll 17 is mounted, which is driven in rotation by a drive motor 18.
  • the glue application roller 17 is immersed in a glue bath 19, above which a squeegee roller 20 is arranged, which is likewise mounted in the glue container 16 and delimits a glue gap with the glue application roller 17.
  • the glue application roller 17 is acted upon by pressing means 21 with a predetermined force in the direction of the upper corrugating roller 5.
  • These pressure devices 21 are designed as hydraulically acted piston-cylinder actuators, as indicated in the drawing.
  • These pressing devices 21 and their control are from the EP 1 086 805 B1 (corresponding US Pat. No. 6,692,602 B1 ), which may be referred to.
  • a pressing device 22 which has a cylindrical guide roller 23, a tension roller 24 and a pressure belt 25.
  • the pressure belt 25 rests against the corrugation 11 of the upper corrugating roller 5 and reverses the direction of rotation with this according to the arrow 26.
  • the design of such pressing devices 22 is well known.
  • a paper web 27 is introduced, which is provided by the corrugations 10, 11 with a corrugation 28.
  • the tips 29 of the respective corrugation 28 are provided in the glue applicator 15 of the glue applicator roll 17 with glue.
  • the remaining areas of the corrugated paper web 27 are not glued.
  • a laminating 30 is fed, which also consists of paper and has the same width as the paper web 27.
  • This laminating 30 is taken from the Anpressband 25 and formed in the between pressing belt 25 and upper corrugating roll 5 Anpress Scheme 31 to the Tips 29 of lying in the corrugation 11 of the upper corrugating roll 5, corrugated Textilbalm 27 pressed and connected thereto.
  • the upper corrugating roll 5 is heated in the usual way.
  • the finished glued, one side laminated with a liner 30 corrugated board 32 runs together with the Anpressband 25 of the upper corrugating roll 5 from. From there it is fed in stripping direction 33 of a take-up device.
  • support rings 38, 39 are mounted on the upper corrugating roll 5, whose average distance c from one another corresponds approximately to the distance a, so that upon movement of the glue applicator roll 17 against the upper corrugating roll 5, the thrust rings 36, 37 for conditioning against the support rings 38 and 39 come, wherein between the cylindrical surface 35 of the glue applicator roll 17 and the corrugation 11 of the upper corrugating roll 5 remains a significantly enlarged gap 40 remains with a gap width d less than the smallest thickness of 0.08 mm of the machine for the paper web 27 is usable paper. For the gap width d, 0.06 mm ⁇ d ⁇ 0.12 mm applies.
  • the pairs of thrust ring 36 and 37 and support rings 38, 39 thus form spacers 41, 42nd
  • Against the support rings 38, 39 is in each case a defined in the machine frame 1 scraper 43 which cleans the cylindrical surface, that is, the support surface 44 against which the thrust rings 36 and 37 can start from contamination by glue, paper fibers and the like.
  • the existing wear-resistant material support rings 38, 39 are - like Fig. 2 can recognize - arranged interchangeable on the corrugating roller 5.
  • Fig. 1 and 3 different from that after the Fig. 1 and 2 essentially only in that the stop rings 36 ', 37' protrude radially further beyond the cylindrical surface 35 of the glue application roller 17. They act directly on the upper corrugating roll 5 laterally formed by the corrugation 11 support surfaces 44 'together and thus form spacers 41', 42 '. Scrapers 43 are also located against the support surfaces 44 '. Also in this embodiment, a safety gap 40 is ensured when the glue application roller 17, for example, start at a crack of the paper web 27 against the corrugation 11 could, what could happen due to the action of the pressing 21.
