Definitions

  • the invention relates to a roll winder roller with a Sheath that has at least one pressure chamber with one Has pressure fluid input, wherein a pressure setting device is provided, with the help of the pressure the pressure fluid in the pressure chamber is adjustable.
  • a roll winder is used to, for example, a web of material a paper web, to a material web roll, for example, a roll of paper.
  • a material web roll for example, a roll of paper.
  • the role here is below yours Own weight in whole or in part on the roll winder roller on.
  • the invention has for its object the operating properties to improve the roller.
  • This task is the in a roll winder roller initially mentioned type solved in that the pressure chamber has a pressure fluid outlet.
  • the pressure fluid is no longer just used to adjust the hardness of the jacket by increasing the pressure or lower. You use that Pressurized fluid also to remove heat from the jacket. It is because of the pressure fluid outlet possible a flow of pressurized fluid from the pressurized fluid inlet to set up pressure fluid outlet. Since now an ongoing exchange of pressure fluid in the pressure chamber can take place, the pressure fluid is able to To remove heat from the pressure chamber and thus from the jacket. This does not prevent that heat is generated by the flexing work. The heat but can be removed before it becomes a leads to excessive temperature increase. Of course you are not limited to only one per pressure chamber Pressurized fluid inlet or a single pressurized fluid outlet to use. If it makes sense, can the pressure medium is also supplied through several inputs and / or several outputs are removed as long as one Removal of heat is guaranteed.
  • the pressure fluid outlet is preferably to the pressure fluid inlet staggered. This is a relatively simple one Measure to ensure that a Flow from the pressure fluid inlet to the pressure fluid outlet he follows. The pressure fluid is then able to Heat from a larger area of the roll shell evacuate.
  • Is preferably between the pressure fluid inlet and a flow path is formed at the pressure fluid outlet, which acts on at least 50% of the volume of the pressure chamber. It has been found that the flow path do not reach all areas in the pressure chamber must to allow heat to be removed. Already the exchange of about 50% of the volume of the pressure fluid allows for sufficient heat balance between the exchanged pressure fluid and the pressure fluid remaining in the pressure chamber. Through this Exchange is sufficient transportation the heat from the pressure chamber and thus from the jacket ensured.
  • the pressure chamber preferably extends in the circumferential direction and pressurized fluid inlet and pressurized fluid outlet are arranged offset to one another in the circumferential direction. This creates a flow between the pressurized fluid inlet and the pressure fluid outlet in the circumferential direction. This makes the flow paths relatively short held. At the same time, however, it is ensured that the entire roller can actually be loaded. The short flow paths ensure that the pressure fluid absorb and remove sufficient heat can.
  • pressure fluid inlet and Pressure fluid outlet are offset by 180 ° to each other. In this case there are practically two flow paths, in opposite directions by half each are guided around the roller.
  • pressurized fluid inlet and the pressurized fluid outlet are arranged adjacent, between Pressurized fluid inlet and pressurized fluid outlet a partition is arranged. This configuration results just a single flow path that runs around the entire Circumference of the roller is led around. But that's what Connection arrangement somewhat simplified.
  • the pressure fluid outlet preferably has a Throttle on. With the help of the choke you can ensure that pressurized fluid flows out of the pressure chamber can, the pressure loss due to the flowing pressure fluid but stays small.
  • the throttle be a variable Has flow resistance and part of Pressure setting device forms. In other words you can not only take measures at the pressure fluid inlet, to adjust the pressure but via the changeable Throttle also at the pressure fluid outlet.
  • the pressure setting device preferably has a Volume setting function on.
  • the heat transfer is depending on, among other things, how much pressure fluid through the pressure chamber flows. The greater the volume flow, the greater the heat transfer. With a smaller one Conversely, there is only one volume flow weaker transport function. Via the volume setting function accordingly, the roller "temper", i.e. you can do that in certain areas Set the temperature of the jacket.
  • the pressure fluid inlet is preferably with a connected by a roll neck guided feed channel and the pressurized fluid outlet with one through one Roll pin guided drain channel connected.
  • the pressure fluid can be controlled from the outside.
  • the hardness the roll shell can accordingly be controlled from the outside become.
  • the feed channel in another Roll neck as the drain channel is arranged.
  • a plurality of pressure chambers are preferably provided the pressure fluid can flow through parallel to one another. This ensures that all parts of the jacket the roller is reliably reached by the pressurized fluid stream be so that due to unfavorable flow conditions no local hot spots can arise.
  • the pressure chambers axially side by side are arranged. So the pressure chambers are in the manner of bicycle tires arranged side by side trained so that there are rings whose pressure can be adjusted. In these rings the Maintain flow of the pressurized fluid in the circumferential direction.
  • pressure chambers in pressure chamber bodies are arranged, the radially outside through an axially continuous protective cover is covered.
  • This protective cover serves to make the Surface.
  • Fig. 1 shows a roll winder roll 1 with a roll body 2 each at its two axial ends has a roll neck 3, 4.
  • the roller 1 can with Help of the roll neck 3, 4 in not shown Be rotatably supported.
  • the roller 1 has a surface 5 on which in operation a winding roll rests, for example one Roll of paper on which a paper web is wound.
  • the protective cover 7 is, in a way, compliant and flexible. However, it has a rigidity that is sufficient to in gaps 8 between adjacent pressure elements 6 are formed not to allow grooves to appear.
  • Each pressure body 6 encloses a pressure chamber 9 which is closed in the circumferential direction of the roller body 2.
  • the pressure chamber 9 thus forms an annular space around the Roller body 2.
  • the roller body 2 has one for each pressure body 6 Pressure input 10 on the one pressure port 11 with the Pressure chamber 9 connects.
  • a pressure adjustment valve 12 is arranged, using a handle 13 a pressure fluid, for example compressed air, under a more or less large pressure from a pressure supply, not shown can get into the pressure chamber 9.
  • roller body 2 has for each pressure chamber a pressure outlet 14 on the with an output port 15 is connected.
  • output port 15 or an associated line is an adjustable one Throttle 16 arranged, the throttle resistance via a Handle 17 is adjustable.
  • the pressure inputs 10 for all pressure chambers 9 and Pressure outputs 4 for all pressure chambers 9 are in each case parallel to the pressure connection 11 or to the output connection 15 connected. It is relative that way easily possible, the same in all pressure chambers 9 Adjust pressure.
  • the pressure connection 11 is in the one roll neck 3 arranged and the output terminal 15 is in the other Roll neck 4 arranged.
  • Pressurized fluid for example Compressed air from the pressure connection 11 to the output connection 15 flows, therefore flows through the roller 1 in axial direction.
  • each pressure chamber 9 in the circumferential direction, as shown schematically in FIG. 2 is shown.
  • FIG. 3 An alternative embodiment is provided in FIG. 3.
  • a partition 20 is arranged, so that there is a flow path 21 which led practically over 360 ° around the roller body 2 is.
  • the roller 1 can now be operated as follows:
  • the pressure setting device 12 By changing the flow resistance of the Throttle 16 and by an appropriate setting of the Pressure setting device 12 can be in the pressure chambers 9 set a pressure.
  • the pressure becomes like this set that the surface 5 of the roller 1 in the desired Way is compliant.
  • the pressure is set relatively large, so that the Surface 5 of the roller 1 is hard. With increasing roll weight the pressure in the pressure chambers 9 is reduced.
  • the pressure in the pressure chambers 9 does not generated by a static air cushion, where only Pressurized fluid, for example pressurized air into the pressure chamber 9 fed in and discharged if necessary becomes. Rather, a constant flow of pressure medium is generated from pressure port 11 to output port 15. This flow of pressure fluid through the roller 1 absorbs heat that is generated when the Pressure bodies 6 and the protective cover 7 formed jacket 22 forms, and leads them to the outside. So that Temperature of the jacket 22 kept within reasonable limits become.
  • the pressure adjustment device 12 By the interaction of the pressure adjustment device 12 with the adjustable throttle 16 can be not only adjust the pressure in the pressure chambers 9, but also a volume flow with which the pressure fluid flows through the roller 1. If a larger volume flow is desired, then the flow resistance of the Throttle 16 are reduced and at the same time the inflow by the pressure adjusting device 12 in one stronger measure to be released. The greater the volume flow the pressure fluid through the roller 1, the more the pressure fluid can remove more heat.
  • a pressure chamber it is also possible in a pressure chamber to set up multiple flow paths. In this case becomes more than one pressure inlet 10 and possibly provide more than one pressure outlet 14. It is also does not require that a flow path 18, 19th or 21 reaches any point in the pressure chamber 9. you only has to make sure that an exchange of Sufficient pressure fluid occurs. That too Pressurized fluid that cannot be exchanged itself give up its heat to the flowing pressure fluid. As a rule, however, is caused by turbulence or other effects result in the desired exchange anyway.
