Definitions

  • the invention relates to a gluing plant in a corrugated board plant. Furthermore, the invention relates to a method for gluing an endless, corrugated material web, in particular a paper web.
  • the invention has the object of developing a gluing unit of the type mentioned in such a way that the spray behavior of the glue is reduced and the glue application is made uniform.
  • the object is solved by the features of claim 1.
  • the essence of the invention is that a pressure-adjusting device is provided which, when the glue applicator roll rolls off the glued material web, even out the pressure forces acting on the forming glue wall.
  • the spraying behavior of the glue, in particular on the lateral edges of the web of material, is thus largely prevented and, as a result, the application of glue to the material web is evened out.
  • Gluing unit has a frame 2, in which a glue application roller 3 is rotatably mounted.
  • the glue application roller 3 is rotatably driven by means of a motor not shown in detail about its central longitudinal axis 4 in a rotational direction 5 and perpendicular to a transport direction 6 of a single-sided laminated corrugated web 7.
  • the glue-on support roller 3 has a lateral surface 8, which is coated with glue 9 during the rotation of the glue application roller 3.
  • a glue container 10 is arranged below the glue application roller 3, in which the glue 9 is received.
  • the glue container 10 is attached to the frame 2.
  • a squeegee roller 11 is provided, which is rotatably mounted in the frame 2.
  • the squeegee roller 11 is rotatably driven about its central longitudinal axis 12 in the direction of rotation 13 and perpendicular to the transport direction 6 of the corrugated web 7 by means of a motor, not shown.
  • the central longitudinal axes 4, 12 define a horizontal plane along which the distance between the central longitudinal axes 4, 12 is adjustable. In this way, a glue pinch gap 14 formed between the glue application roller 3 and the squeegee roller 11 is adjustable, so that the glue 9 can be applied to the glue application roller 3 with a variable thickness.
  • squeegee-scraper 15 which is arranged with respect to the direction of rotation 13 of the squeegee roller 11 behind the glue-squeezing gap 14.
  • the glue 9 which is on the squeegee roller 11 after the squeeze-off nip 14 is scraped off by the squeegee blade 15 and flows back into the glue container 10.
  • the squeegee scraper 15 is fixed to the frame 2.
  • the gluing unit 1 also has a stripping device 16 for vibration damping of the corrugated web 7.
  • the stripping device 16 comprises a first Ausstreifrohr 17 and a second Ausstreifrohr 18.
  • the Ausstreifrohre 17, 18 are rigidly mounted in the frame 2.
  • the Ausstreifrohre 17 and 18 have corresponding central longitudinal axes 19 and 21, respectively.
  • the central longitudinal axes 19, 21 are perpendicular to the transport direction 6 and are arranged relative to one another such that the corrugated web 7 is guided over the glue application roller 3 coated with the glue 9 and in contact with the jacket surface 8 coated with glue 9 occurs.
  • the first central longitudinal axis 19 is arranged in the transport direction 6 in front of the glue application roller 3 and the second central longitudinal axis 21 in the transport direction 6 after the glue application roller 3.
  • the single-faced laminated corrugated web 7 has a smooth cover sheet 23 made of paper and bonded to the cover sheet 23, corrugated paper web 24.
  • the corrugated web 7 is acted upon by a non-described transport device with a web tension and transported along the transport direction 6.
  • Anpress shoe 25 is arranged, which is resiliently fixed by means of a coil spring 26 to the frame 2.
  • the pressure-shoe 25 forms with the lateral surface 8 of the glue-application roller 3, a glue-order gap 27 through which the corrugated web 7 is conveyed.
  • an applicator-scraper 28 which is relative to the direction of rotation 5 of the glue-applicator roll 3 after the Anpress-shoe 25 is arranged.
  • the applicator scraper 28 removes the after the glue-order gap 27 on the Glue applicator roll 3 located glue 9, which flows back into the glue container 10.
  • a pressure adjustment device in the form of a blower 29 is arranged.
  • the fan 29 is fixed to the frame 2 and comprises a fan nozzle 30, which is supplied via two laterally arranged compressed air pipes 31 with compressed air.
  • the compressed air is provided by a compressed air generating device, not shown.
  • the fan nozzle 30 extends over the entire width B of the paper web 24 and has a rear wall 32, a top wall 33 and a bottom wall 34 which are interconnected substantially in the shape of a triangle profile and laterally through a first side wall 35 and a second side wall 36 are completed.
  • the upper wall 33, the lower wall 34 and the first and second side walls 35, 36 together form a nozzle opening 37, which extends transversely to the transport direction 6 of the corrugated web 7.
  • the first and second side wall 35, 36 each have a throttle opening 39 into which the compressed air pipes 31 open.
  • a plurality of throttle plates 38 are spaced from each other, each having a throttle opening 39.
  • the throttle plates 38 divide the fan nozzle 30 into a plurality of sections, for example, a middle section 40 and a first edge section 41 and a second edge section 42.
  • the first and second edge sections 41, 42 each have a width corresponding to a width B R of a first and second Edge region 43, 44 of the corrugated web 7 corresponds. Accordingly, a width of the central portion 40 corresponds to a width B M of a central portion 45 of the corrugated web 7.
  • the nozzle opening 37 has in the central portion 40 compared to the edge portions 41, 42 perpendicular to the corrugated web 7 a lower height.
  • FIG 3 the rolling of the glue application roller 3 is shown by the corrugated paper web 24.
  • the corrugated paper web 24 has alternately a wave trough 46 and a wave tip 47.
  • a glue wall 48 is formed between each shaft tip 47 and the lateral surface 8 provided with glue 9.
  • the glue wall 48 of a first shaft tip 47 delimits, together with the paper web 24, the surface 9 of the glue application roller 3 coated with glue 9 and the glue wall 48 of a second shaft tip 48, viewed opposite to the transport direction 6, a chamber 49 is open at lateral edges 50 of the corrugated web 7.
  • the mode of operation of the gluing unit 1 according to the invention is described below.
  • the glue 9 is taken from the glue container 10 by the glue application roller 3 in the direction of rotation 5 and transported to the glue-squeezing gap 14.
  • a uniform layer of glue 9 is produced by means of the squeegee roller 11.
  • the squeegee roller 11 and the glue applicator roller 3 are freed of residual glue 9 and cleaned by means of the squeegee blade scraper 15 and the applicator roller scraper 28.
  • the corrugated web 7 is conveyed in the transporting direction 6 via the glue application roller 3, the shaft tips 47 of the paper web 24 being brought into contact with the glue 9 applied to the lateral surface 8.
  • the glue 9 is transferred to the shaft tips 47 of the corrugated paper web 24, wherein the pressing shoe 25 reinforces the contact of the shaft tips 47 to the glue 9.
  • the emerging from the glue-order gap 27 shaft tips 47 are provided with glue 9 and can subsequently with a second Decking 23 are glued to a laminated on both sides corrugated web 7.
  • compressed air is passed through the compressed air pipes 31 into the blower nozzle 30.
  • the compressed air first flows into the first and second edge portions 41, 42 of the fan nozzle 30 and from there through the nozzle opening 37 on the glue wall 48.
  • the compressed air also flows through the throttle openings 39 in the central portion 40 of the fan nozzle 30 and from there through the nozzle opening 37 on the glue wall 48.
  • the throttle plates 38 and the throttle openings 39 are configured such that the compressed air strikes the glue wall 48 predominantly in the edge regions 43, 44. This has the consequence that additionally acts on the glue drops 51, a pressure force due to the compressed air in the direction of the chamber 49. The sum of the pressure forces due to the negative pressure in the chamber 49 and the compressed air is thus greater.
  • the glue drops 51 are consequently moved in the direction of the chamber 49, so that spraying of the glue drop 51 is considerably reduced.
  • the pressure force due to the compressed air to a glue drop 51 is greater than in the central region 45, since in the edge regions 43, 44 hardly a negative pressure in the chamber 49 is present.
  • the air flow through the fan nozzle 30 is adjusted so that the resulting pressure force along the glue wall 48 is approximately constant across the transport direction 6. This leads to a uniform application of the glue 9 on the shaft tips 47.
  • the glue spraying can be particularly effectively prevented if the air flow of the fan nozzle 30 is not parallel to the corrugated web 7 exits, but at a shallow angle> 0 ° emerges against this.
  • the air flow direction 57 is shown by way of example in FIG. 3. Due to the oblique impingement of the air flow on the corrugated web 5 and the rebound of the air flow from this, the glue drops 51 are entrained downwards in the direction of the glue applicator roll 3. As a result, a glue spraying can be particularly well prevented.
  • FIGS. 5 and 6 Structurally identical parts are given the same reference numerals as in the first embodiment, to the description of which reference is hereby made. Structurally different, but functionally similar parts receive the same reference numerals with a trailing "a".
  • the essential difference with respect to the first exemplary embodiment is that no pressure-adjusting device 29 in the form of a blower is provided to equalize the pressure forces on the first glue wall 48, but that the pressure-adjusting device 29a has a first seal 52 and a second seal 53 has, which seal the chamber 49 laterally.
  • first and second seals 52, 53 attached to the frame 2 adjacent to the edges 50 of the corrugated web 7 and slidable by means not shown motors transverse to the transport direction 6.
  • the seals 52, 53 are arranged above the glue application roller 3 and formed on its side facing the glue application roller 3 side corresponding to the lateral surface 8.
  • FIGS. 7 and 8 Structurally identical parts are given the same reference numerals as in the first embodiment, to the description of which reference is hereby made. Structurally different but functionally similar parts receive the same reference numerals with a trailing "b".
  • the gluing unit 1b is used to glue the paper web 24, if this is not glued to the smooth cover web 23. From a smooth paper web 24, the corrugated paper web 24 is produced by means of a corrugating roll 54 and the corrugation tips 47 are provided with glue 9. For better illustration of the corrugating roller 54, the paper web 24 is not shown in FIGS. 7 and 8.
  • the corrugating roller 54 is rotatably mounted about its central longitudinal axis 55 and rotatably driven in the direction of rotation 56.
  • the corrugating roller 54 together with the glue application roller 3 forms the glue application gap 27b.
  • the pressure adjusting device 29b is formed in the form of a blower as in the first embodiment.
  • the fan 29b described below can therefore also be used in the first embodiment.
  • the blower nozzle 30b of the blower 29b is formed of the rear wall 32b, the upper wall 33b and the lower wall 34b.
  • the upper and lower walls 33b, 34b form the nozzle opening 37b, through which compressed air flows in the direction of the glue application gap 27b.
  • a plurality of juxtaposed compressed air connections 31b are attached to supply the fan nozzle 30b with compressed air.
  • throttle openings 39b provided in the rear wall 32b. In these throttle openings 39b open the compressed air pipes 31b, so that at different cross sections of the throttle openings 39b in the edge regions 43, 44 of the paper web 24 a stronger compressed air flow can be achieved than in the central region 45. Otherwise corresponds to the operation of the Blower 29b of the first embodiment.
