Definitions

  • the invention relates to a carrier roller winding machine for winding material webs, in particular paper or cardboard webs, on cores according to the preamble of claim 1.
  • the position of the dividing line in the roller bed must be selected so that the newly inserted sleeves clamp the new web start before winding, for each sleeve diameter used. Regardless of the tube diameter, the dividing line is positioned so high up in the roller bed that tubes with the largest diameter still securely clamp the web end. When using sleeves with a small diameter, a longer, overhanging web piece must therefore be wound, which can undesirably form a fold around the sleeve.
  • Another difficulty is gluing the new start of the web to the sleeves. If the sleeves are provided with a trace of adhesive, they have to be positioned with great technical effort during insertion so that the trace of adhesive only comes into contact with the new start of the web during winding, but does not contaminate the support rollers that are not covered by the web (DE-OS 35 27 377). In order to avoid these problems, the adhesive is applied to the web according to the German patent application 40 03 504 mentioned at the beginning. When using sleeves with different diameters, it is then necessary to adjust the position of the web start provided with adhesive strips to the respective sleeve diameter before inserting new sleeves.
  • the invention has for its object a generic To improve the roller winding machine so that when changing the reel, the newly created start of the web can be glued as quickly and safely as possible, even with cores with different diameters.
  • the dividing line can be set at a point in the roller bed below the contact line of sleeves with the smallest diameter on the wrapped support roller regardless of the sleeve diameter.
  • the beginning of the web provided with adhesive is fed safely and under tension.
  • the belts are laid flat against the web in the wrap area of the support roller in order to keep the web beginnings not yet clamped by the sleeve on the support roller.
  • the start of the web is then transported under tension and without creases to the contact line and glued to the sleeves.
  • a plurality of belts arranged at a distance from one another over the working width according to claim 2 enable the application of adhesive strips in the running direction of the web in the spaces between the belts. This prevents the adhesive strips from coming into contact with the straps.
  • the belt tension can be adapted to the respective type of material
  • the separating knife attached above the upper guide rollers according to claim 4 enables a cutting of light types of material when ejecting the full winding rolls.
  • the tape dispenser according to claim 5 can Apply adhesive strips to both the new beginning of the web and the end of the web, while the separating line is positioned in the roller bed when the machine runs out.
  • the adhesive can be applied in one step, i.e. with strips of adhesive extending in the running direction over the dividing line, or in two steps, adhesive strips for attaching the end of the web to the finished winding roll and then adhesive strips for attaching the beginning of the web to the sleeves.
  • the perforating device according to claim 6 enables weakening of the web with heavy types of material. The weakened point is then moved into the roller bed and the web is torn there by increasing the web tension.
  • Fig. 1 shows a side view of a section of a support roller winding machine according to the invention during AufwickeIns.
  • Fig. 2 shows the support roller winding machine during a roll change.
  • FIG. 3 shows an enlarged detail from FIG. 2.
  • the carrier roller winding machine has two driven carrier rollers 1, 2, between which a roller bed 3 is formed, in which the winding rollers 4 rest on the carrier rollers 1, 2 during winding.
  • an ejection bar 26 which can be pivoted via the support roller 1, is attached to lateral pivot levers 6, the pivot axis of which extends coaxially to the support roller 1.
  • the sleeve channel 7 is fastened at the end of lateral pivot levers 10 with a pivot axis running coaxially to the support roller 2.
  • An equally machine-wide, flat support 12 is fastened approximately vertically to a height-adjustable machine-wide traverse 11.
  • the support 12 has a plurality of tab-shaped extensions 13, spaced apart from one another, over the entire working width, at the end of which a deflection roller 14 can be lifted out in a trough.
  • the thickness of at least the upper part of the support 12 and the extensions 13, and the diameter of the deflecting rollers 14 are less than the distance between the support rollers 1, 2, so that it is possible to move the deflecting rollers 14 from a lowered rest position (FIG. 1) to move up through the gap between the support rollers 1, 2 to a working position above the narrowest point of the support roller gap (FIGS. 2, 3).
  • projections 15 are fastened to the looped support roller 1 across the working width at regular intervals with a pin, on each of which a deflection roller 16 with the associated upper roller 14 is flush and freely rotatably supported.
  • the deflection rollers 16 have one significantly larger diameter than the upper pulleys 14.
  • a circumferential elastic belt 17 is tensioned in each case.
  • the projections 15 are slidably attached to the support 12 with the lower deflection rollers 16.
  • the diameter of the lower deflection rollers 16 and their distance from the support 12 is selected so that in the raised working position the adjacent strand 17.1 of each belt 17 bears against the web 5 lying on the support roller 1 in as large an area as possible and the removed strand 17.2 does not abuts the web 5.
  • the belts 17, which are spaced apart from one another over the entire working width, are thus able to hold a web start on the support roller 1 and to guide it upwards during transport.
  • Each belt 17 can be changed quickly if necessary by lifting the upper roller 14 and pulling it laterally off the lower roller 16.
  • a passive cutting knife 18 extending over the working width, z. B. a serrated tear-off blade, which cuts the web 5 when ejecting a full winding roll 4 via the support roller 2.
  • a perforating device 19 is arranged on the inlet side in front of the support roller 1. It contains a toothed perforating blade 20 which can be moved into the web 5 in order to make heavier types of paper, e.g. B. cardboard to weaken along a line of weakness.
  • the web 5 is then - as will be described in more detail later - torn by increasing the web tension along the weakening line as soon as the weakening line is at the desired position in the roll bed 3.
  • the increase in web tension takes place by rotating the full winding roll 4 by means of a support roller 1, 2 against a braking force which, for. B. from the unrolling, not shown is applied.
  • the adhesive strips 23 have a smaller width than the gap between two belts 17, and in each case one adhesive tape dispenser 21 is aligned with one of these gaps, so that the adhesive strips applied to the web 5 do not come into contact with the belts 17 when they occur the web 5 can be adhesively moved into the roller bed 3.
  • a swivel arm 24 which can be pivoted against the support roller 1 is arranged below the support roller 1 in the web running direction in front of the belt 17.
  • the rear deflection rollers of the rocker arm 24 are mounted coaxially to the lower deflection rollers 16 for the belt 17 on the support 12.
  • the pivoting to the support roller 1 takes place by means of a piston-cylinder unit 25 which is articulated on an extension of the cross member 11 extending downwards.
  • the cross member 11 with the belt 17 and the swing arm 24 is lowered into a non-disturbing rest position (FIG. 1).
  • the carrier roll winding machine is stopped so that the web 5 comes to a standstill under web tension.
  • heavier types of paper e.g. B. cardboard that can not be easily cut with the passive separating knife 18 when ejecting the full winding rolls 4
  • the stationary web 5 is weakened with the perforating device 19 depending on the type of material so much that it can be torn later by increasing the web tension .
  • the weakening line is then by restarting the support roller winding machine at a lower speed into the roller bed 3 to below the contact line of the sleeves 8 with the smallest diameter on the support roller 1 moves. During this movement, the pressure roller 22 of the adhesive tape dispenser 21 is pressed against the web 5, so that double-sided adhesive strips are applied to the web 5 over the working width on both sides of the weakening line.
  • the machine is stopped again and the support 12 with the belts 17 is raised.
  • the strands 17.1 of the belts 17 lie under tension in the spaces between the adhesive strips on the web 5 and thus hold the new web start to be created on the support roller 1.
  • the z. B. is applied by a brake in the unwinding of the supply roll, the tensile stress increased so far, that the web 5 tears at the weakened line.
  • the support roller 1 rotates under the web 5 - the web end with the adhesive strips is moved through the contact line between the full winding rollers 4 and the support roller 1, so that the web end sticks to the full winding rollers 4.
  • the support 12 with the belt 17 can already be raised when the perforation is at a standstill in order to place the belt 17 on the web 5 wrapped by the support roller 1.
  • the web 5 is cut by increasing the web tension. This can be done with the machine running slowly, i.e. without standstill. An additional stopping of the machine in order to apply the belts 17 to the web 5 is not necessary.
  • a further shortening of the roll change times is achieved if, instead of the ejection bar 26, a freely rotatable ejection roller is used, with which the full winding rollers 4 are lifted slightly from the support roller 1 before the web 5 is severed.
  • the increase in the tensile stress for severing then takes place by an accelerated rotation of the support roller 2 without the support roller 1 having to rotate under the restrained beginning of the web.
  • the end of the web is glued to the full winding rolls 4 when the adhesive strips pass through the contact line between the winding rolls 4 and the ejection roll.

Abstract

Afin d'enrouler des bandes de papier ou de carton, on connaît les bobineuses ayant deux cylindres porteurs (1, 2), dans lesquelles la bande (5) est déviée par un cylindre porteur (1) et passe de bas en haut à travers la fente entre les cylindres porteurs (1, 2). A des fins de remplacement des bobines enroulées (4), les bobineuses connues comprennent, outre un dispositif de sectionnement de la bande (5), un dispositif d'arrêt de la bande (5) qui peut s'élever à travers la fente entre les cylindres porteurs (1, 2) et s'appuyer sur le cylindre porteur enroulé. Selon l'invention, un appui (12) levable et abaissable agencé sous la fente entre les cylindres porteurs s'étend sur toute la largeur de travail et porte à ses extrémités supérieure et inférieure des poulies de déviation (14, 16) librement rotatives sur lesquelles tourne au moins une courroie élastique (17). Les poulies supérieures de déviation (14) peuvent pénétrer dans la fente entre les cylindres porteurs et les poulies inférieures de déviation (16) sont agencées de sorte que pendant leur élévation, un brin (17.1) de la courroie (17) s'aplatisse sur le cylindre porteur (1) entouré par la bande (5).
