Definitions

  • the invention relates to a carrier roll winding machine for winding a subdivided by longitudinal web of material, in particular a paper or board web having two support rollers, between which a roll bed is formed, on which rest the winding rollers when winding with aligned axes, and with a a pressure roller mounted on a traverse.
  • Material webs must be wound up on shipping or finishing rolls before they can be shipped.
  • roll cores usually winding cores are used, which are preferably made of cardboard.
  • the finished rolls are produced by so-called mother or spool rolls, which are produced at the exit of a paper machine or after the calendering, unwound, cut in the longitudinal direction and then wound on each winding cores.
  • mother or spool rolls which are produced at the exit of a paper machine or after the calendering, unwound, cut in the longitudinal direction and then wound on each winding cores.
  • These cores lie in a winding bed formed by two support rollers of a carrier roll winding machine. At least one of the two idlers is driven.
  • a pressure roller system which consists of a continuous pressure roller or of individual pressure roller segments and is attached to a horizontal, vertically movable traverse.
  • the pressure roller system serves to press at the beginning of the winding from above on the winding rollers, so as to increase the line load at the contact lines between the winding rollers and the support rollers.
  • the winding load of the bobbins is decisively influenced by the line load. At the beginning of the winding line load from the application weight of the winding rolls is not enough to produce the required core winding hardness.
  • the vibrations can have different causes; probably some of the vibrations are induced by the incoming web. For example, variations in thickness in the direction of travel of the material web can lead to a non-circular roll of material, while thickness variations in the transverse direction are reflected in rollers which are not ideally cylindrical and which may have different diameters within the roll width. Since all rolls of a litter are driven by the carrier rolls at a constant peripheral speed, this leads to speed differences between the rolls or roll regions with different diameters.
  • Papers with high coefficients of friction can stimulate vibrations.
  • papers of high density usually calendered grades, caused by this effect winding defects such. B. bars. This makes the more noticeable the greater the friction coefficient of the web is.
  • Such vibrations can be amplified in a resonance range.
  • Relative movements of roller and rollers then "shape" the roles: they become non-circular.
  • the resonance range of the system “rollers / rollers” it comes to mutual excitation.
  • the resonant frequencies in a slitter rewinder are constantly changing. At constant winding speed, the speed of the growing rollers decreases continuously. In addition, the growing roller mass causes the resonance frequencies of the support rollers to decrease.
  • the bobbins can stimulate the machines with a multiple of their rotational frequency. If these frequency curves intersect, a resonance occurs between the rollers and the machine. In the worst case, this leads to the ejection of the bobbins.
  • the swinging parts of the machine also include the traverses. So far, they were made heavy and mechanically stiff from solid sheets, for example, constructed by welded to a rectangle steel plates. As long as a certain rotational speed of the winding machine is not exceeded, such a construction of the traverse is possible.
  • this object is achieved in a winding machine of the type mentioned above in that the traverse has at least one extending perpendicular to the direction of vibration support plate having at least one metallic layer and at least one plastic layer, which covers the metallic layer substantially.
  • a three-layer composite sheet has, for example in cross-section consisting of a first steel sheet, a viscoelastic plastic interlayer and another steel sheet structure, which is characterized by a high sound attenuation and good airborne sound insulation.
  • the cover plates slide slightly back and forth, causing periodic shear deformations in the plastic core layer.
  • the viscoelastic plastic vibrational energy is lost as mechanical energy, d. H. it is converted into heat. This manifests itself in a vibration damping of the composite sheet.
  • Decisive for the structure-borne sound attenuation is the loss factor of a composite sheet, which, based on a forced stationary oscillation, is defined as the quotient of the energy loss per oscillation period and the reversible energy.
  • two-layer composites are also used, whereby the plastic as a damping material can also be laterally applied to an already existing sheet metal construction.
  • an already existing traverse constructed as a double-T carrier can be improved in its vibration damping properties by subsequent coating with plastic.
  • An advantage of an embodiment of the traverse in which this is formed by a hollow body or a double-T-carrier of a composite sheet or a sandwich sheet.
  • a carrier roll winding machine is advantageous in which the hollow body is coated on its insides, in particular on its lower and its upper inner side, with a plastic, preferably a foamed plastic.
  • the composite sheet is folded over in advance in the region of the weld, so that for the welding process, a conductive surface is available and the plastic layer is not damaged.
  • the composite sheet may also be provided with a plastic-free edge zone.
  • the transverse plates reach into inserted into the hollow body slots or project through the slots.
  • the sheet may be superficially treated in a variety of ways, such as electrolytic galvanizing, hot dip galvanizing, fire aluminizing, zinc / aluminum hot dip finishing, and the like.
  • a formed from a folded sheet hollow section 1 forms a traverse for a pressure roller in a winding machine.
  • At least one lower side 2 and one upper side 3 are internally provided with a plastic layer 4, 5, which is either laminated, foamed, laminated, glued or otherwise applied and firmly connected to the respective inner sides of the hollow profile 1.
  • the two lateral sides 6, 7 can be provided with a plastic layer accordingly.
  • the hollow profile 1 is preferably formed by first providing a flat sheet, in particular a steel or aluminum sheet, in particular over the entire surface, with the plastic layer and then folding it.
  • the sheet is in the area of "connection or connection seam", at the two Side edges of the sheet, for example by welding, soldering or other process for joining metal, either folded so that the plastic does not reach the area where the connection process is completed, or the plastic is already in the application of the plastic in the Not applied areas that later form the connection area.
  • transverse plates 8 are suitable for this purpose.
  • this slots 9, 10, 11, 12 preferably on all four sides 2, 3, 6, 7, in which the transverse plates 8 protrude or protrude.
  • the transverse plates 8 protrude or protrude.
  • they already make a firm connection with the hollow profile 1 due to their shape. It is understood, however, that they can also be welded to the hollow profile 1. It should be noted again that the area of the slots 9 to 12 is kept free of plastic.
  • the cross plates 8 may protrude through the slots 9 to 12 and then be bent towards the faces of the sides 2, 3, 6 and 7.
  • a sandwich sheet can be used, which consists of two metal layers and a plastic layer in the middle.
  • layered structures which alternately contain metal and plastic layers and are therefore suitable for damping vibrations.
  • Such layer structures can be used both for the production of the hollow profile described above as well as for other forms of trusses, such as for a traverse in the form of a double-T-beam.
