Definitions
- the invention relates to a winding shaft for winding band-shaped materials, in particular for reel cutting and winding machines for slitting mainly thin metal and steel strip into individual strips and winding the individual strips into reels, with a motor-driven core shaft, tensioning elements for attaching to and from the winding shaft Slip-on and peel-off winding sleeves for the tape rolls and components for transmitting the torque of the core shaft to the individual winding sleeves when winding up the individual tapes with the same or approximately the same tape tension.
- the individual strips that result from the slitting of the thicker central area of the rolled strip are shorter and by the longitudinal parts of the thinner edge portions of the rolled strip emerging single strip or • individual belts are longer.
- the different lengths and Different tape thicknesses of the individual tapes must be compensated for winding all individual tapes with the same tape tension, if the individual tapes are wound on winding cores, which are arranged on a common winding shaft, and all individual tapes are to be wound uniformly firmly.
- a core shaft equipped with friction elements is used in order to kinematically decouple the individual band rolls and to be able to apply defined torques. This is intended to ensure that all tape rolls, regardless of their respective bandwidth, are loaded with specifically the same tape pulls in order to avoid creasing and tensioning within the cutting machine and the destruction of individual material tapes.
- the known winding shaft for winding band-shaped materials on winding cores consists of a core shaft surrounded by friction elements in an annular arrangement and radially acting tensioning elements which, in the operating position, produce a frictional connection between friction elements carried by the core shaft and the friction elements, by means of which a torque from the core shaft slips on the friction elements is transferable.
- the friction elements are movable outwards in order to establish a torsionally rigid connection between the friction elements and the winding tube during operation.
- the tensioning elements move the friction elements outward in the radial direction and bring them about the friction elements in contact with the winding tube in order to reliably ensure a slip-free entrainment of the winding tube with a certain torque.
- the torque transmitted by the friction pairing friction element / friction element is below the torque that can be transmitted by the pairing friction element / winding sleeve, so that a torsionally rigid entrainment takes place between the friction element and the winding sleeve.
- DE 195 15 723 AI describes a generic winding shaft, which consists of a core shaft with longitudinal grooves distributed around the circumference, in each of which a sliding bar facing the outside and an inflatable pressure medium hose are arranged to move the sliding bar radially outward.
- An annular base body sits on the core shaft, on the inner surface of which the slide strips come to rest.
- the sliding strips which extend over the entire length of the core shaft, either consist of oil-soaked felt strips or of a sliding material that can release lubricant.
- On the outside of the base body several obliquely running treads are arranged distributed over the circumference, which interact with tensioning elements designed as balls.
- the balls are arranged in recesses of a clamping ring in such a way that they protrude slightly beyond the outer surface of the clamping ring even when the winding shaft is not tensioned.
- the winding cores are placed on the friction winding shaft. Since the balls protrude slightly beyond the outside of the clamping ring, the winding cores can be easily moved in the axial direction onto the friction winding shaft up to the desired or Postpone required position.
- the individual pressure medium hoses have been inflated beforehand so that there is a frictional connection to the base body via the slide strips and this rotates clockwise along with the rotary movement of the core shaft.
- the balls are pressed further outwards due to the inclined position of the running surfaces, as a result of which the winding sleeves are finally held firmly in their assumed position.
- the balls return to their original position, in which they protrude slightly beyond the outer surface of the tensioning ring, so that the completely wound tape rolls can be easily removed from the winding shaft.
- the invention has for its object to provide a winding shaft of the generic type that enables a uniform winding of tape rolls with different diameters and roll widths.
- the subclaims contain advantageous and expedient developments of the invention.
- the new winding shaft represents an optimal solution to the problem underlying the invention.
- Fig. 1 is a perspective view of a winding shaft
- FIG. 2 shows a cross section of the winding shaft according to line II - II of FIG. 1.
- the winding shaft 1 according to FIGS. 1 and 2 for winding up individual strips 2 for a reel cutting and winding machine (not shown) for dividing thin rolled metal strips into individual strips and winding up the individual strips into strip rolls 3 has a motor-driven core shaft 4 with one in the direction of the shaft axis 5-5 running, continuous flattening 6, in which a cylindrical groove 7 running over the length of the core shaft 4 is designed as a bearing for adjacent pinions 8 with external teeth 9.
- the circumferential angle of the groove 7 of the core shaft 4 is a few degrees larger than 180 °, and the circumferential angle of the outer circumference of the core shaft 4 is substantially larger than 180 °.
- sprockets • 10 are rotatably supported with an internal toothing 11, which meshes with the external toothing 9 of the pinions 8 assigned to the individual toothed rings 10.
- the core shaft 4 with the ring gears 10 forms a closed hydraulic chamber 12 which is connected via channels (not shown) in the core shaft and a feed line for filling with oil and for supplying cooling oil to an oil container with an oil pump.
- the hydraulic chamber 12 is divided into two chambers 12a, 12b by the pinions 8 arranged side by side.
- the two chambers 12a, 12b of the hydraulic chamber 12 and the tooth gaps 14 between the teeth 13 of the ring gears 10 are filled with oil 15.
- winding sleeves 16 On the outer circumference of the sprockets 10, clamping elements (not shown) for clamping the winding tube 16 for winding the individual strips 2 are arranged.
- the winding sleeves 16 When winding individual tapes 2 with the same bandwidth, the winding sleeves 16 have the same winding width that is matched to the tape width.
- Corresponding winding cores 16 with different winding widths are used to wind up individual strips 2 with different widths.
- the winding sleeves 16 are clamped onto one or more sprockets 10 of the winding shaft 1.
- the mode of operation of the winding roll is as follows: At the beginning of a winding process, in which a plurality of individual tapes 2 are wound onto tape cores 4, which are spanned side by side on the core shaft 4 of a winding shaft 1, the core shaft 4, which is driven in the counterclockwise direction a, reveals its speed of value Is brought up to zero to the operating speed, a belt pull B acting on the individual belts 2 is set up, which a restraint pull R counteracts the tape running direction c.
- the individual tapes 2 are wound by the core shaft 4 rotating at a constant operating speed with a constant tape tension B onto the individual winding tubes 16 of the winding shaft 1 to form tape rolls 3, with a balance between that on the individual sprockets 10 due to the oil pressure in the pressure force K acting in the chamber 12b and the restraining cable R so that the ring gears 10 rotate synchronously with the core shaft 4.
- band tension B and the retention tension R on one or more of the sprockets 10 decrease due to a smaller band thickness of one or more individual bands 2 compared to the other individual bands, with the consequence of a smaller winding diameter of the corresponding band reel or band reels 3 compared to the other band reels this sprocket or sprockets 10 due to the decreasing in the chamber 12b compressive force K briefly in a leading rotational movement in the direction of arrow a relative to the core shaft 4, so that the pinion or 8 rotates counterclockwise or until the pressure force K is rebuilt and balanced by the oil pressure in the adjacent chamber 12b.
- a new equilibrium is established between the compressive force K and the restraining force R on the corresponding toothed ring or rings 10 and a constant band tension B on the associated band reel or rolls 3. This operation takes place continuously and continuously during operation.
- the cooling oil is expediently conducted in a cooling circuit by means of a pressure-controlled pump via the unpressurized chamber 12a into the pressure chamber 12b.
- the pinion 8 can be rotatably mounted on an additional shaft.
- clamping elements for the clamping elements for the winding sleeves 16 can be actuated by the pressure oil in the chamber 12b of the hydraulic chamber 12.
