Definitions

  • the invention relates to a winding shaft for winding strip-shaped materials, in particular for slitter and winding machines for slitting mainly thin rolled strip of metal and steel in individual bands and winding the individual bands to tape rolls, with a motor driven core shaft, clamping elements for attaching to and from the winding shaft retractable and peelable cores for the reels and components for transmitting the torque of the core shaft to the individual cores when winding the individual bands with the same or approximately the same strip tension.
  • a core shaft equipped with friction elements is used to kinematically decouple the individual belt rolls and to apply defined torques. This is to ensure that all rolls of tape, regardless of their respective bandwidth, are charged with specific identical tape moves to avoid wrinkling and tension within the cutting machine and the destruction of individual material bands.
  • the known winding shaft for winding tape-shaped materials on cores consists of a frictional elements in an annular arrangement surrounded core shaft and radially acting clamping elements, which produce a frictional engagement between the core shaft entrained friction elements and the friction elements in the operating position, by the slip on a torque of the core shaft the friction elements is transferable.
  • the friction elements are movable outwardly to produce a torsionally rigid connection between the friction elements and the winding tube during operation.
  • the clamping elements move by means of the radial forces applied by them on the friction elements, the friction elements in the radial direction to the outside and bring the friction elements in contact with the winding tube to reliably ensure a slip-free entrainment of the winding tube with a certain torque.
  • the torque transmitted by the friction pair friction / friction element under the transferable by the pairing friction / winding sleeve torque, so that between the friction element and winding tube a torsionally rigid entrainment takes place.
  • DE 195 15 723 A1 describes a generic winding shaft, which consists of a core shaft distributed around the circumference arranged longitudinal grooves, in each of which an outwardly facing slide bar and an inflatable pressure fluid hose are arranged to move the slide bar radially outward.
  • On the core shaft sits an annular body, on the inner surface of the sliding strips come to rest.
  • the over the entire length of the core shaft extending wear strips consist of either oil-impregnated felt strips or a sliding material that can deliver lubricant.
  • On the outside of the main body distributed over the circumference a plurality of inclined running surfaces are arranged, which cooperate with trained as balls clamping elements.
  • the balls are arranged in recesses of a clamping ring such that they protrude slightly in the untensioned state of the winding shaft over the outer surface of the clamping ring.
  • the cores are attached to the friction winding shaft. Since the balls protrude slightly beyond the outside of the clamping ring, the cores can be very easily in the axial direction of the friction winding shaft to the desired or respectively postpone required position.
  • the individual pressure medium hoses have been inflated, so that on the slide strips a frictional engagement with the base body takes place and this along with the rotation of the core shaft rotates clockwise accordingly.
  • the balls are pressed further outwards due to the inclined position of the running surfaces, whereby finally the winding tubes are held firmly in their assumed position. In the relaxed state of friction, the balls return to their original position in which they protrude slightly beyond the outer surface of the clamping ring, so that the finished wound tape rolls can be easily removed from the winding shaft.
  • Fritationswickelwellen it is difficult, especially for small roll diameters to transfer a large torque from the core shaft on the winding tubes of the individual rolls of tape and to achieve a uniform tape tension uniform winding of the individual material bands.
  • the invention has for its object to provide a winding shaft of the generic type, which allows a uniform winding of tape rolls with different diameters and roll widths.
  • the new winding shaft represents an optimal solution of the invention underlying task.
  • the winding shaft 1 for winding single belts 2 for a roll cutting and winding machine not shown for slitting thin rolled strip of metal in individual bands and winding the individual bands to tape rolls 3 has a motor-driven core shaft 4 with a in the direction of the shaft axis 5-5 extending, continuous flattening 6, in which a running over the length of the core shaft 4 cylindrical groove 7 is formed as a bearing for adjacent pinion 8 with an external toothing 9.
  • the circumferential angle of the groove 7 of the core shaft 4 is larger by several degrees than 180 °, and the circumferential angle of the outer periphery of the core shaft 4 is substantially larger than 180 °.
  • sprockets 10 are rotatably mounted with an internal toothing 11, which is in engagement with the external teeth 9 of the individual sprockets 10 associated pinion 8.
  • the pinion 8 and the sprockets 10, which are each rotatably mounted in series next to each other in or on the core shaft 4, are each liquid-tight against each other and against the both ends of the core shaft (4) sealed liquid-tight.
  • the core shaft 4 forms with the sprockets 10 a closed hydraulic chamber 12 which is connected via channels, not shown, in the core shaft and a supply line for filling with oil and for supplying cooling oil to an oil reservoir with an oil pump.
  • the hydraulic chamber 12 is divided into two chambers 12a, 12b.
  • the two chambers 12a, 12b of the hydraulic chamber 12 and the tooth gaps 14 between the teeth 13 of the sprockets 10 are filled with oil 15.
  • clamping elements for clamping of winding tube 16 for winding the individual strips 2 are arranged on the outer circumference of the sprockets 10.
  • the cores 16 When winding single bands 2 with the same bandwidth, the cores 16 have a width of the same width shredded width. For winding single bands 2 with different bandwidth corresponding cores 16 are used with different winding width. Depending on the winding width, the cores 16 are clamped onto one or more sprockets 10 of the winding shaft 1.
  • the operation of the winding roll is the following: At the beginning of a winding process, in which a plurality of individual belts 2 wound on side by side on the core shaft 4 of a winding shaft 1 winding tubes 16 are wound to tape rolls 3, is driven by the counterclockwise a driven core shaft 4, whose speed is increased from zero to the operating speed a Bandzug B acting on the individual bands 2 constructed, the a remindzugszug R counteracts the tape running direction c.
  • the individual bands 2 are wound by the rotating at a constant operating speed core shaft 4 with a constant strip tension B on the individual winding tubes 16 of the winding shaft 1 to tape rolls 3, with a balance between the on the individual sprockets 10 due to the oil pressure in the chamber 12 b acting compressive force K and the remindzugszug R sets so that the sprockets 10 rotate synchronously with the core shaft 4.
  • the cooling oil is expediently conducted in a cooling circuit by means of a pressure-controlled pump via the non-pressurized chamber 12a into the pressure chamber 12b.
  • the pinion 8 may be rotatably mounted on an additional shaft.
  • clamping elements for the clamping elements for the cores 16 by the pressure oil in the chamber 12 b of the hydraulic chamber 12 can be actuated.
