Definitions

  • the invention relates to a roll winder roller with a elastic surface layer on a core, in whose surface openings are arranged.
  • Such a roll winder roller is, for example known from EP 0 683 125 A2.
  • the openings in the surface serve to structure the surface, to make the cover "softer" than that elastic surface layer forming material and is for itself.
  • others can Serve surface structures, for example circumferential, spiral or cross-shaped grooves or pimple-like elevations.
  • the invention is based on a paper web described that wound up into a paper web roll becomes.
  • other material webs for example cardboard or foils made of metal or plastic.
  • the problem also arises with textile webs if they are not or only partially permeable to air.
  • a scraper blade is provided in DE 29 44 958 A1, the on the paper roll and possibly on the Paper web rests to scrape the air off the web.
  • the invention is based, the risk the floating of the material web even at higher speeds to reduce.
  • This task is the in a roll winder type mentioned solved in that each opening via a duct in connection with an air intake volume stands, at least in the circumferential direction of the Roller is completed.
  • the air intake volume must of course be of a certain size in order to accommodate the indented Also take in air practically without resistance can. However, this is easily possible. Because the openings be kept relatively small in the surface marking of the material web can be avoided become. Of particular advantage, however, is the characteristic that the air intake volume is completed in the circumferential direction is. So there are no connections or short circuits between individual openings in the circumferential direction. Accordingly, the roll winder roller also used to seal a changing bed be in which with the help of compressed air a weight relief the winding roll is effected. The compressed air can also be pressed into the air intake volume become. An escape through connecting channels, which run approximately in the circumferential direction, however not possible.
  • the air intake volume is preferably dependent of the operating speed of the roller so great chosen that the pressure rise is less than 50 mbar remains.
  • the roll winder roller has an operating speed, that of the target speed of the Roll winder is specified. Depending on the Operating speed, i.e. the peripheral speed the roller, the web of material becomes a certain Drag the amount of air to its surface. The higher the Speed, the greater the amount of Air and the larger the air intake volume must be chosen become. The necessary minimum size can be find out relatively easily by simple experiments.
  • the air intake volume preferably points in the axial direction and / or radial direction a larger extent than the channel on. So you can see the air intake volume provide a sufficient size without the cross section of the channel or the size of the opening must choose excessive. With this combination there is enough space to to absorb the air layer adhering to the material web. On the other hand, a marking of the material web effectively avoided.
  • air intake volumes are essential connected to each other in the axial direction.
  • a Connection of the air intake volumes in the axial direction harms with regard to the relief of compressed air Not winding roll, because then all openings and Air intake volumes that are interconnected are always subjected to the same pressure.
  • the size by the "cross connection" of the connected air intake volumes quite considerably increase so that with a low constructive High impact can be achieved can.
  • the openings are preferably each in a line arranged opposite an axially parallel line includes a predetermined angle. You get there with the fact that not all at one revolution of the roller Openings in a row at the same time as contacting the Material web come. This results in a smoother run. Out of roundness is kept small or even avoided. This also helps to reduce the marking risk at. By placing the channels under one predetermined angles to the surface can still be Use axially parallel connection channels.
  • the air intake volume preferably has during operation a predetermined minimum size. Air is in compressible to a significant degree. To the adherent however, as mentioned above, being able to take in air is a certain minimum volume is necessary. Dependent on of where the air intake volume is located it in operation due to the prevailing loads, e.g. the weight of the winding roll or the tensile force of the material web, to a deformation of the boundary walls this volume of air intake come, for example then when one or more boundary walls of the Air intake volume still in the elastic surface layer are arranged. Through the channels and the Cavities that form the air intake volumes the elastic property of the surface layer is not be significantly changed. Nevertheless, are smaller Deformation cannot be excluded. According to the invention now ensured by appropriate dimensioning that the air intake volume is maintained, at least with a given minimum size.
  • the air intake volume an essentially constant variable in operation having. This can increase pressure in the air intake volume be avoided if, for example, the corresponding Air intake volume under the nip or nip that the winding roll comes with the roll winder roller forms.
  • the air intake volume is preferably within one Insert arranged radially below the surface.
  • the insert can be made relatively stable, so that the risk of deformation of the air intake volume stays small. Even if the stake is not completely ensures that deformation takes place, he can keep the deformation small.
  • the insert is preferably formed by the core.
  • the channels are at least through the surface layer drilled through or otherwise produced.
  • At its core which is usually made of steel or cast iron, this results in a sufficiently stable boundary wall for the cavities in which the air intake volumes be formed.
  • the use can be made by essentially one axially extending tube be formed. Naturally this tube can also make a small angle with the Include axial direction.
  • Such a pipe can for example in the elastic surface layer be embedded.
  • the inside a roller shell is arranged, which forms the core.
  • the roller is, as is often the case, as a hollow roller educated. You can get one in the hollow interior Insert the insert, for example radially outwards springs and axially extending on its radial outside Has recesses, which then with the core forming shell forms the cavities that the air intake volumes take up.
  • the volume of air intake is advantageously at a limit arranged between two layers of material. This makes it easier production. You can see the individual Air intake volumes when manufacturing the roller relative easily generate it by placing it on the outside of a Provides material before the next, radially further external material is applied. For example the air intake volumes on the border between the core and the surface layer or within a boundary between two layers of material Surface layer may be provided.
  • blind holes are advantageous provided in the surface. These blind holes can only be used to a limited extent to the adhesive Take in air. With those in question The radial thickness of the roll winder roll is sufficient Extent usually not sufficient to be sufficient to provide a large volume of air intake. But they can be used to make the elastic To change the properties of the surface layer.
  • openings or openings and Blind boreholes penetrated less than 15% of the area Surface. In most cases, it will be enough keep it between 10 and 15%. So that the material web and the winding roll is adequately supported. On the other hand, there is enough cross-sectional area available through which the adhering to the material web Air can kick.
  • each air intake volume in a continuous axial direction the front closed chamber is arranged is divided axially by at least one partition.
  • you can with a simple construction of the roller Take changing roll widths into account.
  • This training the roller allows a relatively simple manufacture.
  • the at least one partition is advantageous arranged stationary. This is enough if you do it beforehand knows which roll widths to wrap. If you arrange several partitions stationary, then you can correspondingly many different roll widths wrap.
  • the partitions are preferably by means of clamping plugs educated.
  • Clamping plugs for example from one material comparable to rubber, can be axially in the chamber be driven. There is a certain Effort is necessary, but without the manufacturing more can be made available. As soon as the Stoppers have reached their intended location, clamp them tight. The clamping force is sufficient for the due to the air pressure in the changing bed to resist. Here, the clamp connection does not have to be absolutely tight. The tightness between the plugs and the wall of the chamber only has to be sufficient to ensure that the weight relief of the Maintain the necessary pressure in the changing bed remains.
  • At least one partition in Is designed to be movable and fixable in the axial direction can be provided.
  • the partition must just put between the two openings which are inside and outside an axial Limit of the pressurized zone of the changing bed.
  • two partitions are in opposite directions in pairs movable.
  • they can be to the axial plane of symmetry always adjust symmetrically. This makes it easier the setting of roll widths in particular then if only ever a single winding roll or axially adjacent winding rolls are wound.
  • the same in the air intake volume opening in the circumferential direction have a smaller distance from each other than from openings, which in an adjacent in the circumferential direction Air intake volume flow out. This eliminates the risk that in the circumferential direction a "short circuit" arises, through which Escape pressure from the pressurized changing bed can, kept small.
  • that the air intake volume via at least one relief hole with a compensation volume in connection stands. This can ensure an even better adhesion of the material web can be reached on the surface of the roller.
  • relief drilling is not intended here be limited to being pierced by a Process is established.
  • the relief hole can also be generated in other ways.
  • the air adhering to the material web can through the Open the opening and the duct into the air intake volume.
  • the resulting pressure increase is not excessively large, but measurable.
  • the higher pressure can as the roller continues to rotate through the relief bore be dismantled again.
  • the air can namely through the relief hole in the compensation volume flow away. Because when the material web on the Surface of the roller has come to rest, no other If air is replenished, the material web comes after a predetermined time used to depressurize is, so after a predetermined angle of rotation the roller, to a very dense and therefore firm system to the surface of the roller.
  • the facility is so firm and stable that the material web runs sideways practically no longer on the surface of the roller he follows.
  • the compensation volume is preferably through an interior space formed, which is surrounded by the roll shell. This interior is available for many rollers anyway Available, which are designed as a hollow roller. If can use this interior as compensation volume you save yourself complicated cable routing.
  • the interior advantageously has a connection to the surroundings on.
  • One can use the connection for this ensure that the pressure inside is the same, like in the environment, so atmospheric pressure.
  • This Design has the advantage that the interior does not have to divide into a zone that corresponds to the printing area, i.e. the outlet area, is adjacent, and a Zone that is the infeed area for the web of material is adjacent. Rather, it allows that in the printing area Small amounts of compressed air in the interior can penetrate. This causes a pressure increase but not instead because of the pressure from the connection can escape to the environment. Accordingly leads this pressure increase also does not lead to a lifting of the material web in the "infeed area" of the roll winder roller.
  • the air intake volume is preferably in the axial direction divided into several chambers and each chamber has at least one relief hole.
  • This Design makes it easier to adapt the roll winder roller to different widths of the winding roles. Air from the compressed air support area can not then in the axial direction by the Escape aerial view volume. Still there is the possibility available that in the infeed area air adhering to the material web into the compensation volume can drain off.
  • the relief bore is preferably a throttle channel educated.
  • This throttle channel forms a flow resistance for the air. That means that from entrained air that leads to a slight increase in pressure in the air intake volume, can flow through the throttle. Because for this one is available for a relatively long time, namely the Time in which the material web on the roller surface is present, which is quite about angular ranges in the order of magnitude from 120 to over 180 ° can be the case the material web can at least at the end of this wrap angle very firmly on the surface of the Put the roller on. With the sudden pressure increase, like when the corresponding surface area enters into the compressed air support zone the throttle, however, has a relatively large pressure drop. Air can also come from the air intake volume flow into the compensation volume.
  • the air volume can even have a larger pressure difference be larger than in the inlet area. But it is always enough not yet out to a noteworthy pressure drop to lead in the air intake volume. Accordingly the pressure in the compressed air support zone too not significantly lowered, i.e. it is practically none additional power for feeding a larger one Air volume in the compressed air support area necessary.
  • the relief bore can be provided with a valve.
  • This valve opens when the corresponding sector of the Roller is in the infeed area, so if from the material web entrained air through the relief bore should drain off. However, the corresponding one comes Roller sector in the exit area where due to the compressed air support the increased air pressure prevails, then the valve is closed and the outflow of air will be prevented.
  • valve is self-closing Valve is formed.
  • the valve remains open. This is in Infeed area the case.
  • the pressure difference bigger as is the case if the corresponding Air intake volume comes into the outlet area, then the valve is closed.
  • the valve can be designed in the manner of a check valve, that is kept open by springs or other forces, which are only overcome by a larger pressure difference can be.
  • the air intake volume is preferably through a pipe formed, which is arranged in an axial groove in the core, whose side walls overlap the tube towards the outside.
  • a groove can be created, for example, by that first with an milling cutter with an axial groove a rectangular cross section is generated. Subsequently you can mill these grooves with a form cutter. Then when you push the tube in, it's in the radial direction, so against the centrifugal force, sure held. This is a relatively easy to implement and yet reliable solution.
