Definitions
- the invention relates to a roll winder for winding a material web to a material web roll with at least one roller that has an elastic layer on it has the surface and with the web roll forms a nip during operation.
- the invention is based on a paper web described as an example of a material web. she is but can in principle also be used with other material webs, which are handled in a similar manner, for example Cardboard, foils or textile webs.
- a paper web that is produced practically endlessly must become a roll at the end of the manufacturing process be wound up so that they can be transported and handled can be.
- rollers are used for winding, the one core or one on the Set the roll of material web forming the core in rotation.
- the roll winder can have different designs to have. On the one hand it can be a double carrier roller winder act in which the material web roll in a changing bed that consists of two support rollers is wrapped. It can also be a backup roll winder act in which the roll of material is centric is held and additionally on a backup roller is applied. In both cases it is known to be additional to use a pressure roller, at least at the beginning the winding process a pressure on the web roll exercises to increase the winding hardness.
- All of these rollers usually have an elastic one Surface layer.
- the surface layer is particularly on the rollers on which the material web roll rests, compressed during winding. The compression increases with increasing diameter and thus increasing Weight of the web roll too. This affects the winding hardness of the material web roll.
- different roller coverings i.e. surface layers used. If you want to wrap different Do not replace the paper types want, you have to cover or the surface layer from the outset as a compromise between different ones Train requirements. But with that under certain circumstances no type of paper is optimally wound.
- the invention has for its object the winding result of the roll winder with different material webs to improve.
- This task is the beginning of a roll winder mentioned type in that the influence of Layer adjustable to the winding hardness of the material web roll is.
- the effective hardness of the Layer is changeable. This is a relatively simple one Measure to determine the influence of the layer on the winding hardness adjust the material web. The harder the layer is, the greater the winding hardness of the web roll. It is not absolutely necessary the properties of the material of the layer too change. It is sufficient if the effective hardness of the Layer is changeable, i.e. the hardness on the Material web roll works.
- the depth of penetration of the web roll is changeable in the roller. This is a relatively easy way to get effective hardness to change. The greater the depth of penetration of the material web roll the lower the effective hardness the layer.
- the layer preferably has alternative spaces whose Size is changeable. If the alternative rooms are large then the material of the layer at a Pressurization to a large extent in the alternative rooms dodge. The material of the layer can thus displaced into the alternative rooms under the winding pressure become. This creates the effect of a soft topping. The result is a large-scale load-bearing Effect and thus a low nip pressure and a low one Winding hardness. If the alternative spaces are reduced then the material of the layer is in front and behind displaced the nip as a bead. Because the volume of the Layer when winding but must pass through the nip a greater "flow rate" of the covering and thus a higher winding hardness. The change in size the alternative spaces are therefore relatively simple Measure to the effective hardness and therefore the influence adjust the layer to the winding hardness.
- the layer in the axial direction the roller is divided into several sections between where the alternative rooms are arranged.
- the size of the alternative rooms can be made clear on the one hand establish.
- the size of the alternative rooms change easily. This change can for example, by packing provides that are used in the alternative rooms can.
- the distance between the sections is changeable. You then have the sections shift something in the axial direction of the roller if one want to change the hardness of the layer. Such one Relocation is usually without major problems possible.
- Each section preferably has one on a roller body arranged socket on that by a ring is surrounded, which forms the layer.
- the sockets can to be moved on the roller body to the distances to change between sections. If the sockets are closely adjacent, then there is only a smaller one Alternative space available. Accordingly, it can Do not dodge the layer material as well. The effective hardness of the layer is increased.
- the sockets preferably have a common drive on. So you no longer have to use every socket relocate. Rather, it is enough to drive the whole to actuate the effective hardness of the layer to change the surface of the roller.
- the bushings are preferably between in the axial direction a clamping device and a stop clamped and between the sockets is a reset device arranged.
- a reset device arranged between the individual sections.
- the reset device formed by an elastic spacer ring is.
- the spacer ring for example one made from a suitable elastomer Material existing ring, then acts as a spring, i.e. it increases when the pressure increases
- the tensioning device compresses and stretches when it decreases of pressure. This is a relatively simple one Possibility of a sufficiently powerful spring to be arranged between the individual sections.
- At least one section is preferably in the axial direction fixable. So it is possible to have different To create zones on the roller whose hardness varies is adjustable. The setting of the properties the surface layer then takes place in several Steps. First, the hardness of the layer in one Zone set the farthest from the jig is removed. After that, the zone delimiting Section in the axial direction on the roller body established. The hardness of the surface layer between the stop and the specified section remains unchanged even if the pressure of the tensioning device is changed. By changing the pressure then you can see the hardness in one zone on the other Change the page of the specified section. To set the sections can be provided, for example, that the sockets are designed as clamping rings, or others Provide ways to place the bushings on the roller body hold.
- Fig. 1 shows schematically a roll winder 1 for winding a paper web 2 (or another material web) to a winding roll.
- the paper web 2 passes through a slitter 3, in which it is divided into several lanes.
- the single ones Partial webs are wound up into separate partial web rolls, as is known in itself.
- a corresponding roller can also be used as a carrier roller in one Double carrier roller winder or as a pressure roller in a roll winder can be used.
- the support roller 4 on its surface an elastic layer that is compressed when the web of material under her Weight. the support roller 4 rests.
- each section has a socket 9 which a roller body 10 displaceable in the axial direction is.
- Each socket 9 is circumferentially one Ring 11 surrounded.
- the ring 11 is formed from the material which is the layer on the surface of the backup roller 4 forms, that is, the covering of the backup roller 4th
- the support roller 4 has a tensioning device 12, in the direction of a double arrow 13 on the roller body 10 can be moved, and a stop 14th at the other axial end of the roller body 10.
- a tensioning device 12 in the direction of a double arrow 13 on the roller body 10 can be moved, and a stop 14th at the other axial end of the roller body 10.
- the spacer rings 15 serve as a reset device, i.e. they press the bushes 9 in the axial direction apart.
- Distances 16 are formed between the individual rings 11, which serve as an alternative space, as in the following will be explained with reference to FIGS. 4 and 5.
- the size the distances 16 is by means of the tensioning device 12 changeable.
- the tensioning device 12 changeable.
- the jig 12 When the jig 12 is operated is that the individual bushings on the stop 14 to be moved, then the distances decrease 16 and thus the size of the alternative spaces between the individual rings 11. If the clamping device 12 so is actuated that the sockets 9 under the action of Spacer rings 15 are moved away from the stop 14, then The distances 16 and thus the alternative spaces increase between the rings 11.
- clamping rings 17, 18 can not only on the roller body 10 in the axial direction, but also in not shown in a manner once ingested Position determined on the roller body 10 become. This makes it possible to lay the covering in several zones set differently.
- the clamping ring 17 is then on the Roller body 10 set in the axial direction. The effective one Hardness in this zone is then retained.
- FIG. 4a shows a view corresponding to FIG. 3 without a roll of material web.
- 4b shows the situation when a material web roll 19 rests on the rings 11.
- Fig. 4c shows a schematic view of the deformation of the covering, which is formed by the rings 11.
- Fig. 5 shows the same representation for the case that the bushings are tightened.
- the distances 16 between individual rings are reduced to zero. So there is no more alternative spaces in which the material of the rings 11 can dodge. Under the winding pressure caused by the web of material 19 is exercised, the material the rings 11 in front of and behind the nip as a bead 20 repressed. But since the volume of the topping, i.e. of the material the rings 11, when winding through the nip, more precisely said through the nip passage d, must result a greater "flow rate" of the covering and thus a higher winding hardness. The depth of penetration e becomes reduced.
- the hardness of the rings 11 is retained per se. Since the material of the rings 11 is no longer in the alternative spaces formed by the distances 16 are, can be displaced, the effective hardness, i.e. the hardness to which the web roll 19 is exposed is changed by changing the size of the distances 16 changed.
