Definitions
- the invention relates to a winding device for winding a material web to a material web roll with a changing bed in which the material web roll is rotatably mounted, and a pressure device, the at least during a portion of a winding process on the upper half of the circumference in the direction of gravity the web of material acts.
- the invention is based on a paper web described as an example of a material web. she is but also applicable to other webs of material that too Rolls of material have to be wound up.
- Paper webs are produced in relatively large lengths. In order to be able to handle paper webs, they have to at least in sections wound up to material web rolls become. This is usually a role core, i.e. a cardboard tube or a tube from another Material, rotated and pulls the paper web on itself.
- the roll of material web is in one Changing bed, i.e. it is in at least two places Circumferential direction supported.
- the support points work usually also driving, for example when they are formed by support rollers, of which at least one is driven.
- winding hardness should at least approximate from the inside out be kept constant, or better still, from the inside fall off to the outside. This is without additional measures not realizable.
- the winding hardness is affected by the weight with which the material web roll rests on the support points in the changing bed. ever the greater this pressure, the greater the winding hardness. Because the dead weight of the material web roll with increasing diameter would increase without additional Measure also increase the winding hardness, which is undesirable is.
- the greatest possible winding hardness is desired, among others can be realized in that the Pressure device used with the roll core a great force in the changing bed.
- the invention is based, the possibilities expand to influence the winding hardness.
- This task is the beginning of a winding device mentioned type in that the pressure device has at least two pressure elements, the Load effect can be set independently of one another is.
- the pressure elements on opposite Sides of a vertical plane through the The axis of rotation of the material web roll are preferred.
- the Both pressure elements then have an additional task: you can namely the web of material with a Hold increased reliability in the changing bed.
- the vibration behavior of the web roll be positively influenced. this in turn has a positive effect on the setting of the winding hardness the web of material.
- the pressure elements preferably practice a resulting one Force on the web of material, which in the Inlet area of the changing bed generates a different pressure than in the exit area of the changing bed.
- the pressure ratios are simply through the different effects of the pressure elements generated.
- the pressure elements result Exert force on the material web roll, which generates a lower pressure in the inlet area than in the exit area of the changing bed. Accordingly is the pressurization influencing the winding hardness the winding roll in the outlet area higher, which is has a positive effect on the winding hardness curve.
- the pressure elements are preferably independent positionable from each other on the circumference of the material web roll. This creates another possibility the influence of the pressure elements independently to shape each other.
- the pressure elements can So first with different forces on the material web roll Act. But you can also, related to a vertical plane of symmetry through the winding roll, at different positions on the circumference of the material web roll attack. So it's no longer necessary that the loading of the material web roll through the pressure device symmetrical to a vertical Plane through the axis of rotation of the material web roll runs. Through a "skewed" pressurization pressure conditions in the support points the material web roll achieve so far were not yet possible.
- the distance between the pressure elements is preferably one another variable. This makes it possible for small Material web roll diameters on the pressure elements to allow the scope of the roll of material to act, on the other hand but with larger web rolls the attacking ones Forces far enough apart so that you actually through the multiple pressure elements has the possibility of different pressures in to produce the support nips.
- the pressure elements are preferably at least one predetermined diameter of the web roll an angular distance of 45 ° ⁇ 15 ° to the apex position the material web roll arranged.
- the pressure elements are arranged in a segment, which is the middle third of the top two quadrants the roll of material includes. This has proven to be cheaper Location for the position of the pressure elements highlighted.
- the changing bed is preferably formed by supporting elements formed in the outlet area softer than in the inlet area are. Such an arrangement is in itself known. In connection with several pressure elements, the load effect can be set independently However, there are further options. For example, the harder one Apply additional pressure to the inlet point than in the softer outlet area.
- the support element preferably has in the inlet area a different curvature than in the outlet area. If if you use rollers as support elements, then you have the Another roller in the infeed area, for example larger diameter than in the outlet area. This too Measure is known per se, but is obtained by several Pressure elements, the load effect independent is adjustable from each other, an additional possibility of influencing.
- the changing bed is preferably inclinable. Through this Measure it in a simple way, the dead weight the role more on the base on Inlet or stronger towards the support point at the outlet lay. Together with the differently acting pressure elements it is now possible to get through the weight of the material web roll practically exclusively to put on the inlet or the outlet or set an intermediate value.
- Each pressure element preferably exerts a force the web of material that is directed into the changing bed is. The risk of malfunction is thus low one of the pressure elements the web roll is pushed out of the changing bed.
- At least one pressure element preferably has one Drive on. This provides an additional possibility to influence the winding hardness.
- the Another drive preferably via the pressure element Torque on the circumference of the web of material than another drive.
- both pressure elements have a drive and the drives with different Driving torques act on the winding roll. This allows a web tension on the circumference of the Generate material web roll, which during further winding is "wrapped".
- a winding device 1 has a winding bed 2, in a web roll 3 rests.
- the material web roll 3 is formed by a core 4, on which a material web 5 is wound. To do that The material web roll 3 rotated by the elements that make up the changing bed 2 form.
- the elements forming the changing bed 2 are here Case two support rollers 6, 7, the inlet side Carrier roller 6 with the web roll 3 an inlet nip 8 and the outlet-side support roller 7 with the Material web roll 3 forms an outlet nip 9. Since the Carrier roller 6 at the inlet nip 8 a larger diameter as the support roller 7 on the outlet nip 9, is Curvature of the support element formed by the support roller 7 larger at the outlet nip 9 than at the inlet nip 8.
- Both support rollers 6, 7 each have a drive 10, 11, the drives 10, 11 with different Driving torques act on the material web roll 3 can.
- support rollers 6, 7 for formation of the changing bed 2 can of course also other support elements be used.
- a or both carrier rollers are replaced by an arrangement, where a belt is guided over pulleys and the material web roll 3 rests on the belt.
- the material web roll 3 by a compressed air support of their own weight in the inlet nip 8 and in the discharge nip 9 to relieve.
- first pressure element 12 On the top half of the circumference of the roll of material 3 acts a first pressure element 12, which by a Pinch roller is formed, and on the opposite Side of a vertical plane of symmetry 13 through the axis of rotation 14 of the material web roll 3 acts a second pressure element 15, which also is formed by a pressure roller.
- the two are Pressure rollers 12, 15 within certain limits on the Scope of the material web roll 3 shiftable. You move preferably in the middle segment Third of the upper quadrant of the material web roll 3. Of course, other positions are also possible. The positioning the two pressure rollers 12, 15 can done independently.
- a force is indicated by arrows F1, F2, with which the two pressure rollers 12, 15 on the web roll 3 act.
- the two forces are F1, F2 directed into the changing bed 2.
- the two forces F1, F2 can be chosen independently.
- the two pressure rollers 12, 15 can each have their own Have drives 18, 19, the drive torques of the two drives 18, 19 also independently of one another can be adjusted.
- the two drives 18, 19 are therefore able to handle different winding tensions impress in the outermost layer of the material web 5, these winding tensions then wrapped up can be.
- the Load effect can be set independently of one another there are a variety of new ways that Press in the inlet nip 8 and in the outlet nip 9 to set. If, for example, the pressure roller on the inlet side 12 lowered and the pressure roller on the outlet side 15 closer to the vertex of the web roll 3 moves, it is possible to adjust the pressures in the inlet nip 8 to lower it sharply and raise it strongly in the outlet nip 9.
- the inlet-side pressure roller 12 exercises one Force component on the material web roll 3, which too leads to a certain relief in the inlet nip 8. Naturally reverse loading is also possible, so that the pressures in the inlet nip 8 are greater than in Outlet nip 9.
- the two pressure rollers 12, 15 also use the material web roll 3 specifically pushing out or pushing out of the changing bed 2.
- the pressure elements are one with the surface the material web roll 3 circumferential surface exhibit.
- Such a surface can, for example also be formed by a circumferential band that is guided over at least two pulleys.
- the two pressure elements 12, 15 can of course also Known ways of influencing the winding hardness be combined. So it is also conceivable that the outlet side Carrier roller 7 with an elastic covering is provided and in this respect by a wide inlet nip 8 a lower pressure on the forming web roll 3 exercises.
- the larger, in the course of Material web 5 front carrier roller 6 could e.g. a have hard metal surface and by the larger Apply less pressure to the roller bearing surface.
