Definitions

  • the invention relates to a method for winding a Material web to a roll on a contact roller is present and at least over part of the winding process from a loading roller to the contact roller is pressed, at which the material web when reached of a predetermined roll diameter and the end of the material web on the roll and the beginning of the material web on a new winding tube is stuck.
  • the invention further relates to a Winding device for winding a material web a roll with at least one contact roller, one Load roller attached to one in relation to the contact roller displaceable traverse is arranged and one Adhesive dispenser, which is arranged on the crossbar.
  • a web of material becomes wound into a winding roll, which when winding in a winding bed is formed by two support rollers is. When the winding roll is finished, it will ejected from the changing bed. The web of material will then stretched between the two support rollers.
  • a winding sleeve is placed on the material web and through held a pinch roller. On both sides of the pinch roller adhesive dispensers are provided, each a strip of adhesive on the material web Instruct. If the material web is then cut, the end of the material web is glued to the winding roll and the beginning of the new material web on the winding sleeve.
  • US 4,572,451 A shows a method and an apparatus for winding a material web into a winding roll, which lies in a changing bed when wrapped, which by two support rollers is formed.
  • an adhesive dispenser is provided below the changing bed which contains an adhesive on the underside of the web. The train runs through the changing bed onto the Winding roll on.
  • the invention is based on a paper web described as an example of a material web. She is but not limited to that, but can also work with others Material webs are used that are similar Way like a paper web need to be wound up. Paper webs are used in one of the final manufacturing steps wound into rolls that are transported and can be handled. Such roles then have for example a width between 0.3 and 3.8 m and a diameter in the range of about 0.8 to 2.5 m. Possibly is for generating the correct web width still a slitting process is required, which is usually performed in a so-called slitter becomes.
  • a limiting factor in the utilization of the winding devices is the time it takes to change roles needed. These downtimes can be up to 30 account for up to 40% of the winding times.
  • the invention is therefore based on the object Simplify role changes.
  • This task is carried out in a method of the type mentioned at the beginning Art solved in that an adhesive strip in an area in the vicinity of the load roller is applied to the roll, the roll rotated further and then ejected, a new winding tube is inserted and the loading roller on the The winding tube is lowered using an adhesive strip on the winding tube in an area in the neighborhood the loading roller is applied.
  • the glue dispenser required to apply the adhesive strip can be kept close to the load roller so it interferes with the winding process not, but is when applying the adhesive strip already in the right place. So you don't need any additional time in which the adhesive dispenser is on the right position is brought.
  • the load roller is usually on the contact roller opposite side of the roll. Accordingly is the applied adhesive strip in the Time the reel spins about half a time exposed to atmospheric oxygen, which in many cases too an increase in the stickiness of the adhesive strip leads. Then when the adhesive strip in the nip between the roller and the contact roller from the inside to the outermost Position of the material web is pressed, you get with high reliability a good adhesive result for the End gluing.
  • the adhesive is always on the same side of the load roller is applied and on the side on which the material web on the Roll comes up. So that the adhesive does not come with the Load roller in contact, but the load roller always runs on a circumferential section of the roll or the winding tube, which is free of adhesive or in the the adhesive is covered by the material web.
  • the adhesive is preferably applied over the entire length the role applied simultaneously. So you need no time to put an adhesive dispenser over the roll to let traverse.
  • this configuration the advantage that the adhesive strip over the entire axial length of the roll is essentially one has uniform adhesive force. This results in a better one Wrapping quality or an improved durability of the End of web on the circumference of the roll.
  • the adhesive is sprayed on. With spraying you get one very quickly high initial adhesive strength, which is particularly true when manufacturing the end sheet gluing is desirable. About that In addition, the consumption of adhesive here can be kept low become.
  • the task is at the beginning of a winding device mentioned type solved in that the adhesive dispenser to an area in the neighborhood of a Support nips of the load roller works.
  • the adhesive dispenser is so arranged that it on the one hand does not interfere with the winding, on the other hand for Always apply the adhesive strip to the correct one Position is. It becomes with the movement of the load roller, the ones to adapt the situation to itself changing diameters necessary when changing rolls is automatically tracked so that neither additional Additional tax funds are still required are, for example, additional drives and their controls, so that the role change is also inexpensive can be carried out. You have the option of both the size of the roll, its largest diameter has managed to act as well as a winding sleeve with a much smaller diameter. Though the adhesive is not immediately between the load roller and the roll or the winding tube applied because in this case there is a risk that the loading roller is contaminated. You will be the Connect the adhesive application relatively close to the area can in which the loading roller on the Roll or the winding tube rests.
  • the material web preferably runs over the contact roller closed and the adhesive dispenser is on the side arranged the loading roller from which the material web running towards the roll.
  • Adhesive can increase its adhesiveness to one to achieve particularly good initial adhesive strength.
  • the adhesive dispenser preferably has the same Spread like the crossbar. So it is possible to total axial length of a roll simultaneously with adhesive to be provided so that the adhesive force over the axial length of the roll can form evenly. This improves the quality in particular of the end sheet bonding.
  • the adhesive dispenser is preferably used as an adhesive spraying device educated. If the glue or the adhesive is sprayed onto the roll, then he usually unfolds the high one relatively quickly Initial adhesive force, possibly because it is intense comes into contact with atmospheric oxygen.
  • the Spraying is easy to control. You can with one Spraying also apply a certain width, see above that overall the adhesive surface more easily to the adhesive requirements can be adjusted.
  • Fig. 1 shows a winding roll 1, which is in a winding bed 4 rests, which is formed by two support rollers 2, 3 is.
  • the support roller 2 By driving the support roller 2 in the direction of a Arrow 5, the winding roll 1 in the direction of Arrow 6 driven.
  • the support roller 3 can also be driven his.
  • the carrier roller winder shown can also be a so-called backup roller or Contact roller winder can be used in which the roll 1 is held centrally and below a predetermined and optionally adjustable pressure on a Contact roller is applied.
  • a web of material 7, which is wound up on the winding roll is, the support roller 2 wraps from above, before them through a nip 8 between the roll 1 and the Carrier roller 2 runs and then pulled onto roll 1 becomes.
  • This side of roll 1, i.e. half on the in Fig. 1 left side of a vertical plane through the Axis of roller 1 is referred to below as the "inlet side" designated.
  • a loading roller is located vertically above the winding bed 4 9 arranged on a cross member 10, the Means not shown, but known per se can be moved in the direction of the double arrow 11 can, so lowered to the changing bed 4 or, with increasing Roll diameter of roll 1, from the changing bed can be lifted up.
  • the loading roller 9 is used especially at the beginning of a winding process to press the forming roll 1 1 into the changing bed 4, order one at the beginning of the winding process to produce great winding hardness.
  • the load roller 9 can be divided several times in the axial direction be as possible over the length of the cross member 10 to ensure even support.
  • An adhesive dispenser 12 is arranged on the cross member 10 on the entry side.
  • the adhesive dispenser 12 is designed as an adhesive spraying device, which extend over the entire length of the traverse 10 extends.
  • the adhesive spray device 12 is therefore able to run simultaneously along the entire length of the Roll 1 adhesive in the form of a glue bead 13 on the Spray surface of roll 1.
  • the adhesive dispenser 12 can also be divided into individual zones, the individual are controllable, so that it on changing roll widths can be adjusted.
  • the glue bead 13 comes into the nip 8, see above that the incoming material web 7 fixed on the roll 1 becomes.
  • the adhesive is exposed to atmospheric oxygen. Together with the spray technique when applying, with also a relatively good connection with atmospheric oxygen takes place, the adhesive 13 can be a relatively good one Unleash the initial adhesive force. This is a final sheet gluing guaranteed of high quality, which also without more time can be generated.
  • a new winding tube 14 for example a cardboard tube, placed in the changing bed 4.
  • the traverse 10 is lowered with the aim of the loading roller 9 to place on the winding tube 14.
  • the Adhesive dispenser 12 takes action again and sprays another glue bead 13 'on the winding tube 14. If now the support rollers 2, 3 are rotated and the loading roller 9 the winding tube 14 into the winding bed 4 presses in which the front end 15 of the material web 7, then sticks after a short turn the material web 7 on the winding tube 14. Here there is a little less time available to to increase the stickiness of the adhesive 13 '. This is but not critical, because the material web 7 after a few Rotations of the winding tube 14 not only from the adhesive 13 'is held, but also by the train.
  • the adhesive dispenser 12 sprays the adhesive 13, 13 ' always so on the roll 1 or the winding tube 14 that the loading roller 9 is not dirty with adhesive is, but the adhesive 13, 13 'first of the incoming Material web 2 is covered before Adhesive 13, 13 'passed under the loading roller 9 becomes.
