Definitions

  • the invention relates to a method for changing winding rolls in machines for winding material webs, in particular paper or cardboard webs on sleeves, according to the preamble of claim 1 and a device for carrying out the method.
  • DE 36 11 895-Al describes a generic method in a back-up roll winding machine in which the web is first weakened before reaching the back-up roll, a trace of adhesive is applied to both sides of the weakening and the web is separated by braking on the back-up roll.
  • the web ends held by vacuum on the support roller are moved to the full winding rolls and glued to them.
  • the newly created beginnings remain with this Movement braked until the brake is released after unloading the finished rolls and inserting new winding cores, thus transporting the beginning of the web provided with adhesive tape from the support roller to the winding cores and adhering to them.
  • DE 40 03 504-A1 describes a carrier roller winding machine in which a perforating device and a plurality of adhesive tape dispensers for dispensing double-sided adhesive tapes across the working width are arranged on the infeed side, which dispense their adhesive tapes in the direction of web travel.
  • the adhesive tapes can thus be attached by means of the moving web.
  • the invention has for its object to improve a generic method so that only one adhesive dispenser is required to apply the adhesive strips without the machine downtimes being extended.
  • only one adhesive dispenser is required, which first applies the adhesive strips to the transfer element. This can happen during rewinding the material web, so that the downtimes are not extended. If the roll change takes place at shorter intervals than is required for applying the adhesive strips to the transfer element, two adhesive dispensers are sufficient, which apply adhesive strips to the transfer element from both sides simultaneously over the working width.
  • a free-running transfer roller according to claim 2 allows the adhesive strips to be attached by means of the moving web.
  • Claim 3 contains an advantageous variant for changing roles with heavier types of paper, for. B. carton.
  • the web is first weakened and adhesive strips are applied to both sides of the weakening line.
  • the weakening line can then be moved into the position that is desired for gluing the new beginning of the web to new sleeves. After cutting the web, both the end of the web - for gluing to the full winding roll - and the newly created web beginning - for gluing to the new winding cores - have adhesive strips.
  • Claim 4 contains a particularly advantageous variant of the method according to claim 3 for changing full winding rolls against new winding sleeves in support roller winding machines with two driven support rollers, on which the winding rollers rest during winding.
  • Claims 5 to 10 contain preferred devices for carrying out a method according to Claims 1 to 4. Brief description of the drawing
  • FIG. 1 and 2 show a side view of an adhesive application device according to the invention which, when used on a winding machine, applies a plurality of adhesive strips running in the direction of travel of the web next to one another at a distance.
  • FIG. 3 shows an adhesive application device which applies a wide strip of adhesive transversely to the web running direction.
  • FIG. 4 shows a paper web with parallel strips of adhesive applied in the direction of web travel.
  • FIG. 5 shows a paper web with a wide strip of adhesive across the direction of travel.
  • FIG. 6 shows an adhesive application device with which one or more traces of glue are applied.
  • the support roller winding machine shown only in part in the drawing has two driven support rollers 1, 2, on which the winding rollers 3 rest during winding.
  • the material web 4 preferably a paper or cardboard web, which is divided in the longitudinal direction into individual webs, is deflected from below, by the support roller 1, through the gap between the support rollers 1, 2 into the roller bed 5 and wound onto aligned sleeves.
  • Such double carrier roll winding machines are widely known and z. B. in DE-OS 32 07 461, so that details, insofar as they do not relate to the invention, are not discussed.
  • levers 6 At both ends of the feed roller 1 on the inlet side, levers 6 are attached which can pivot about the support roller axis and carry a swivel cross member 7 which extends across the working width.
  • a freely rotatable ejection roller 8 for ejecting the full winding rollers 3 over the support roller 2 is attached to the top of the swivel cross member 7.
  • the swivel traverse 7 On its underside, the swivel traverse 7 carries a counterholder 9, which extends over the working width, to a perforating device 10, which has two support surfaces 11, 12, between which there is a groove. By pivoting the swivel traverse 7, the support surfaces 11, 12 - as shown in FIG. 2 - can be moved against the web 4.
  • the perforating device 10 has a toothed knife 14 which extends over the working width and which is both removed from the web 4 by means of a lifting unit 15 and, as shown in FIG. 2, for perforating the web 4 in the groove of the lowered one Bracket 9 can be pressed.
  • a lifting unit 15 for perforating the web 4 in the groove of the lowered one Bracket 9 can be pressed.
  • two clamping elements 17, 18, which are resiliently mounted on the knife holder 16 laterally next to the knife 14 and can be pressed against the support surfaces 11, 12 of the counter holder 9.
  • a device 19 for applying an adhesive is arranged below the support roller 1. It has a transfer roller 21 which extends over the working width and is rotatably mounted on swivel arms 20 by means of a drive and can be moved from below against the web 4 in the wrap region of the support roller 1.
  • the surface of the transfer roller 21 is such that the adhesive adheres to it less firmly than to the material web 4, i. H. it has a lower adhesion than the material web 4.
  • an adhesive tape dispenser 22 is arranged below the transfer roller 21 and is mounted on guides 23 transversely over the working width - that is to say parallel to the carrier roller axis.
  • the adhesive tape 24 is guided in the direction of travel of the web 4.
  • a supply roll 26 made of an adhesive tape 24 with a double-sided adhesive layer of adhesive adhering to a carrier tape 27 is freely rotatably mounted in the carriage 25 which can be moved transversely to the web.
  • the adhesive tapes used in the paper industry are used, the adhesive layer of which is very easily detached from the carrier tape 27.
  • the adhesive tape 24 is guided upwards on the carriage 25 and guided against the direction of travel of the web 4 up to an adhesive tape-wide pressure roller 28, which deflects it downward to a driven spool 29 for the carrier tape 27.
  • the pressure roller 28 can be swiveled up against the transfer roller 21 in its lowered position by means of a piston-cylinder unit 30.
  • Fig. 1 shows the support roller winding machine during the winding: the perforating device 10 and its counter-holder 9 are at a non-disturbing distance from the web 4.
  • the transfer roller 21 is lowered so that it is also at a distance from the web 4.
  • a plurality of parallel adhesive strips 31 are applied to the surface along the direction of travel of the web 4.
  • the pressure roller 28 wrapped in the adhesive tape 24 pivots from below against the transfer roller 21.
  • the adhesive tape 24 is unwound from the supply roller 26 and an adhesive strip 31 is picked up by the transfer roller 21.
  • the remaining carrier tape 27 is wound up by the spool 29.
  • the pressure roller 28 is pivoted, whereby the adhesive layer of the Adhesive tape 24 tears off.
  • the carriage 25 then moves transversely to the web running direction into the next adhesive tape delivery position.
  • the transfer roller 21 is rotated back into the take-up position so that the taken-up adhesive strips 31 lie in alignment.
  • the next adhesive strip 31 is now transferred to the transfer roller 21.
  • a number of parallel adhesive strips 31 which are aligned transversely to the running direction of the web 4 are applied to the transfer roller 20, preferably this is done approximately every 200 mm. It is also possible to adjust the positions of the adhesive strip 31 as a function of the longitudinal knife positions so that the adhesive strips 31 are evenly distributed on the individual webs.
  • the carrier roller winding machine is stopped.
  • the web 4 comes to a standstill under web tension due to the braking force that is applied by a rolling device, not shown.
  • the swivel cross member 7 is moved downward, so that the support surfaces 11, 12 of the counter-holder 9 bear against the web 4, and the web 4 is weakened by perforation.
  • the cutting knife 14 moves upwards and with its tips through the web 4 into the groove between the support surfaces 11, 12.
  • the web 4 is clamped between the clamping elements 17, 18 and the support surfaces 11, 12 and is thus kept taut .
  • the transfer roller 21 pivots against the support roller 1 from below and lies against the web 4.
  • the transfer roller 21 is rotated so that the circumferential distance between the contact line 32 to the web 4 and the center of the adhesive strips 31 corresponds approximately to the distance between the contact line 32 to the separating knife 14.
  • the separating knife 14 is then lowered with the clamping elements 17, 18 and the transfer roller 21 is switched to freewheeling.
  • the support roller 1 is then again with reduced web tension started, with the adjacent transfer roller 21 also rotating.
  • the adhesive strips 31 are pressed against the web 4 under pressure at the contact line 32, whereby they detach from the transfer roller 21 and stick to the web 4, since the adhesion to the web 4 is greater than to the transfer roller 21.
  • the perforation line 33 of the web 4 has meanwhile also advanced to the contact line 32, so the adhesive strips 31 are located on both sides of the perforation line 33 on the web 4 (FIG. 4).
  • the transfer roller 21 is lowered again and can again take up adhesive strips in this position for the next roll change.
  • the web 4 is moved further until the weakened web site (perforation line 33) with the adhesive strips 31 is in the roller bed 5 above the gap between the two support rollers 1, 2.
  • the web 4 is stopped there and the brake on the unwinding device is locked in order to hold back with maximum force.
  • the winding roller 3 with the ejection roller 9 is raised a little by the wrapped roller 1 and rotated by means of the roller 2.
  • the web 4 now tears through the perforation line 33, so that there are adhesive strips 31 both at the end of the web that is running and at the beginning of the new web.
  • the newly created beginning of the web is held on the support roller 1, this can e.g. B. by suction by means of vacuum or by means of mechanical holding elements.
  • the full winding roll 3 is rotated further until the web end provided with adhesive strips 31 has been moved through the contact line to the support roller 1 or to the ejection roller 8, so as to glue the web end to the full winding roll 3.
  • the full winding roll 3 with the ejection roll 8 is ejected via the support roller 2 and a new set of tubes is inserted into the roller bed 5.
  • the support rollers 1, 2 are set in motion again in order to bring the new beginning of the web provided with adhesive strips 31 into contact with the sleeves bring.
  • a durable adhesive connection of the web 4 with the sleeves is established when the beginning of the web with the adhesive strips 31 has passed through the gap between the sleeves and the support roller 1.
  • the carrier roller winding machine can then be accelerated to the maximum winding speed.
  • a broad, double-sided adhesive strip 34 is applied transversely to the running direction of the web 4, that is to say parallel to the axis, on the transfer roller 21 (FIG. 5).
  • the carriage 25 of the adhesive tape dispenser 22 is mounted such that it can be moved across the working width, the axes of the pressure roller 28 and the supply roller 26 extending perpendicular to the axis of the transfer roller 21. So that a sufficiently wide strip of adhesive 34 can be applied to the transfer roller 21 in a flat manner, the pressure roller 28 is concavely curved on its circumference in the axial direction. This can e.g. B. can be achieved by using so-called diabolo rolls.
  • the pressure roller 28 presses the adhesive tape 24 - as explained in the previous embodiment - against the transfer roller 21 while the carriage is moved over the entire working width. The pressure roller 28 is then lowered, the adhesive layer of the adhesive tape 24 tearing through. So that the adhesive tape is applied to the transfer roller 21 more quickly, an adhesive tape dispenser 22 can be arranged on each side of the machine, which then applies the adhesive strips 34 to one half of the transfer roller 21. The adhesive strips 34 are transferred to the web 4 in the manner described above by pressing the transfer roller 21 onto the web 4.
  • FIG. 6 A further embodiment is described in FIG. 6, in which the double-sided adhesive strips of adhesive are produced on the transfer roller 21 by spraying.
  • one or more glue nozzles 35 are located below the transfer roller 21, either over the entire web width arranged or traversable across the track.
  • the nozzles 35 By means of the nozzles 35 one or more traces of glue, for. B. sprayed by a dispersion adhesive that set to double-sided adhesive strips. They are then transferred to web 4 in the manner described above.
