Definitions

  • the invention relates to a reel in accordance with the preamble of Claim 1 and to the use of a reel in accordance with the invention.
  • wound rolls of paper or other winding material in the form of a web is carried out on a winding machine of a carrier roll (or reel) construction or back-up roll (or reel) construction.
  • a carrier roll winder For a carrier roll winder, the winding rests on two rotating carrier rolls arranged parallel to each other.
  • a back-up roll winder the winding is supported to rotate on a shaft, which for its part is fastened to swinging arms .
  • the construction details of a carrier roll winder differ sharply from those of a back-up roll winder. However, in connection with the invention they both share in common that a roll parallel to the axis of a winding being formed, e.g., a roll in the form of the aforementioned carrier rolls, back-up roll, or a weighting roll, is supported against the winding being formed.
  • a nip force develops at the contact line between winding and roll, the so-called nip; this nip force rises, at least for a carrier roll winder, as the diameter of the winding increases, the diameter being synonymous with the increased weight of the winding.
  • the web traction in particular and, for a carrier roll winder the distribution of turning moment (torque) are responsible for the winding hardness or winding tension. As the diameter of the winding becomes greater, the circumferential tension generated by means of the weight of the wound roll rises, which can lead to an overstretching of the wound material, e. g. paper, to the point of tearing.
  • Web traction and the distribution of turning moment can be regulated and controlled by means of known methods. Decreasing the nip force is connected with greater cost.
  • winding methods are known, particularly for a carrier roll winder, for which the weight of a wound roll is carried entirely or partially by means of devices which pass through the core of the wound roll, such as winding shafts or grip heads (chucks); the latter are known from back-up roll win- ders .
  • the technological advantage of this type of carrier roll winder is connected with high cost; in addition, it is extremely costly to configure automation in order to increase productivity.
  • the angle of the plane which passes through the carrier roll shafts can be adjusted relative to a horizontal plane.
  • a winding device comprises, apart from two carrier rolls, an elastic belt placed under tension by means of a tension roll, supported to be movable, which belt wraps around one of the two carrier rolls and a clamping roll.
  • the spatial arrangement of the rolls around which the belt is wrapped provides for the development of a relieving component on the weight of the roll during the entire winding process .
  • US 3,098,619 discloses a winding device for which 3 rollers are mounted on a framework in such a way that two of the rollers form a uniplanar roller pair, i.e., a plane which is placed through the roller shafts of the roller pair is parallel to a plane tangential to the winding throughout the entire winding process.
  • the spacing of the rollers of the uniplanar roller pair is as small as possible, such that pressure waves which originate from the nip of each of the rollers can superimpose each other.
  • a moving belt can rotate around all three rollers and can be put under tension by means of the third roller.
  • the uniplanar position of the roller pair is maintained by means of a drag-link on the basis of the equilibrium of force.
  • DE 4,035,054 which has as an object, a roll of the same generic class having a thin-walled metal running sleeve.
  • DE 4,035,054 proposes to mount the metallic running sleeve to the roll body over an elastic, flexible intermediate layer.
  • a mounted thin-walled metal running sleeve no axial force appears in an axial direction, in contrast to a roll having an exclusively elastomeric roll cover or else a rubber sleeve, such that the winding quality is not impaired in the way which occurs for a roll having a compressible roll cover.
  • the diameter of the carrier roll is responsible to a decisive degree, in accordance with Hertzian stress, for the specific nip force.
  • the diameter of a carrier roll is increased, the specific nip force falls for a wound roll of equal weight.
  • the diameters of back- up rolls and carrier rolls cannot be enlarged by any optional amount .
  • the purpose of the invention is to create a roll with which the winding hardness can be adjusted in accordance with the desires of a further processor and, in particular, can be kept small without impairment to other aspects of the winding quality and without enlarging the diameter of the roll.
  • the basic idea in accordance with the invention is that, on one hand, the hardness or ductility of the thin-walled running sleeve on the basis of its wall thickness and its material-specific properties, such as elastic modulus, determines the obtainable winding hardness; on the other hand the position of the arrangements of supporting elements relative to the nip, i.e., to the contact location between roll sleeve and wound roll can be used as a controlling or regulating component for winding hardness.
  • the supporting device as a whole can pivot around the shaft of the roll.
  • the supporting device preferably is pivoted in such a way that one of the arrangements of supporting elements supports the running sleeve from the inside, on or near the contact location.
  • the supporting device is pivoted such that, in accordance with the requirements for a necessary smaller nip force, the nip is located between two adjacent arrangements of supporting elements, so that the running sleeve can give way to the nip pressure.
  • the invention is realized with a supporting device for which the angle between at least two of the arrangements of supporting elements can be varied.
  • the shape of the running sleeve changes, e.g., from round to oval (in the shape of a rotary piston), such that for the latter shape, the radius of curvature at the contact location corresponds with that of a roll having a greater roll diameter.
  • the variation of the angle(s) between the arrangements of supporting elements also can be superimposed by a pivoting of the supporting device, such that the effects of both solution alternatives appear simultaneously.
  • the mutual spacing of the arrangements of supporting elements is changed by means of radially displacing at least one of the arrangements of supporting elements with respect to the roll shaft.
  • the supporting elements are executed as rollers, with either one roller per arrangement of supporting elements being able to extend across the entire roll width, particularly for a short roll, or with several rollers of the same diameter being arranged on one shaft with spacing between each other, particularly for a wide roll.
  • a winding device in accordance with Claim 9 represents the preferred field of application.
  • the roll can be driven in a preferred way by means of a driving roller which acts upon the outside of the roll sleeve.
  • a driving roller which acts upon the outside of the roll sleeve.
  • the introduction of turning moment should be carried out at a location, the angular distance of which from the nip is as great as possible, preferably on or near to that arrangement of supporting elements which supports the running sleeve from the inside on the side facing away from the nip.

  • the width of the roll 50 extends at least across the entire winding width of the winding device.
  • the roll 50 has a shaft L, about which can rotate a cylindrical, preferably seamless, single-piece running sleeve 1. It is preferable to use a thin-walled tube as the running sleeve.
  • the running sleeve also can be assembled in the sense of the invention from several tubular sections.
  • the running sleeve preferably consists of an elastically ductile metal, the elastic modulus of which is selected in such a way that a thin-walled running sleeve of a selected wall thickness gives way above a certain pressure, yet the flexural strength is sufficient to maintain a convex curvature of the running sleeve even in unsupported zones of the sleeve.
  • supporting elements 2A, 2B, 2C in the form of a carrier roller system arranged radially about the shaft L of the roll 1 serve as an inner support for the running sleeve 1; the arrangements of supporting elements 2A, 2B, 2C likewise are constructed, in each case, of several carrier rollers 4A, 4B, 4C arranged on a supporting element shaft S aligned parallel to the shaft L.
  • a supporting device 10 having three carrier roller systems 2A, 2B, 2C is described in the example. Two, four or even more carrier roller sys- terns also can be used in accordance with the roll diameter and intended use.
  • the individual carrier rollers 4A, 4B, 4C of the carrier roller systems 2A, 2B, 2C are supported on a common, non-rotating carrier device which extends across the entire width of the roll 50; in the example, this is shown as the shaft 5, as is particularly clear from Figure 5.

  • the smaller roller width of that/those carrier roll(s) 4C which are located adjacent to the bearings 6 which support the running sleeve 1 can minimize or equalize negative effects caused by means of the bearings 6 on the degree of deformation of the run- ning sleeve 1.
  • a carrier roll winder features a first carrier roll 51 and a second carrier roll 52.
  • the first carrier roll 51 has a construction in accordance with the invention as in Figures 1 and 2, while the second carrier roll 52 is in the form of a conventional carrier roll.
  • a material web (M) wraps around a section of the running sleeve 1 of the first carrier roll 51 up to the contact location N (Nip) with a winding tube 11.
