Definitions

  • the invention relates to a driver element according to the preamble of claims 1 and 2.
  • the new role In order to perform a flying role change, the new role must be accelerated until the peripheral speed of the linear velocity of the running paper web corresponds exactly.
  • the torques required to accelerate the roll of material are transmitted by appropriately suitable drive systems.
  • so-called belt drive systems are known in which drive belts come to rest on the circumference of the new roll and accelerate the new role by appropriate frictional engagement.
  • so-called core drives are known in which the required drive torques are transmitted to the receiving elements on both sides of the roll of material at the Inner circumference come to the plant.
  • a mandrel is known for example from EP 04 53 800 B1.
  • radially driven staking jaws are provided on the receiving element, which can be moved apart after the arrangement of the receiving element in the core of the roll of material, thereby to produce a frictional connection between the roll of material and the mandrel.
  • the roll of material slips over the jaws due to their high weight and the resulting high acceleration moments during acceleration or deceleration. This unwanted slippage can lead to irregularities in the movement.
  • the core of the roll of material can be damaged by the slipping of the jaws, so that a secure attachment of the roll of material on the mandrel is no longer given.
  • DD 82615 describes a clamping device for winding tubes, in which a plurality of dowel pins are pressed with knife-like cutting into the winding tube.
  • the invention has for its object to provide a driver element, a method for producing a driver element and a mandrel.
  • the achievable with the present invention consist in particular that by the Arrangement according to suitable driver elements a positive connection between the roll of material and mandrel can be produced. Due to the positive connection a substantially reliable transmission of the drive torque is ensured.
  • the mechanically complex drive means for adjusting the force or frictional driver elements omitted.
  • the driver elements are arranged on the mandrel such that they can be brought to the front side of the roll of material for engagement and extending substantially parallel to the longitudinal axis of the roll of material.
  • driver elements are provided, which are arranged in an annular ring around the center of the receiving element.
  • the number of driver elements can be increased according to the forces to be transmitted.
  • driver element In order to produce the positive connection between the driver element and roll of material, appropriate receptacles may be provided on the roll of material, in which the Driver elements of the mandrel when Aufachsen the roll of material can be engaged.
  • the production of such recordings on the material roll means an additional production cost.
  • This additional manufacturing effort can be saved if a cutting edge is provided on the driver element. Through this cutting edge, the driver element can penetrate into the material of the roll of material, for example into the wall of a cardboard tube, with a relatively low press-in force, whereby a tearing or tearing of the material of the roll of material is ruled out by the cutting edge at the same time.
  • the mandrel 01 shown in Fig. 1 is attached to a frame of a roll changer 02 in a web-fed rotary printing press.
  • a rotationally symmetrical receiving element 03 is provided, which can be wound on the inner circumference of a roll of material 04, in particular on the inner circumference of a cardboard tube 04 onto which a material web, in particular a paper web, can come to rest.
  • the receiving element 03 is rotatably mounted with roller bearings and can be driven in rotation by means of an electric drive.
  • the mandrel 01 is shown enlarged by the Aufachsen the roll of material 04.
  • Circularly distributed around the center of the receiving element 03 a plurality of driver elements 06 are arranged on the mandrel 01, of which in Fig. 2, only one driver element 06 is.
  • the directed towards the end face of the roll of material 04 end of the driving element 06 has a cutting edge 07 which penetrates the collapse of the mandrels 01 in the end face of the roll of material 04 and thereby produces a positive connection between the roll of material 04 and the mandrel 01.
  • the structure of the driver elements 06 is exemplary in the drawings Fig. 4 to 7 shown.
  • the cutting edge 07 of the driver element 06 is formed by two intersecting cutting surfaces 08 and 09, which include a wedge angle ⁇ of 25 ° to 45 °, in particular approximately 34 °.
  • Both cutting surfaces 08 and 09 have a convex shape, since they are formed by sections of intersecting cylinder jacket surfaces.
  • the convex curvature of the cutting surfaces 08 and 09 can be seen in particular from the cross-section A - A shown in FIG. 7.
  • This type of design of the driver element 06 ensures that the tip of the driver element 06 is loaded during torque transmission with a substantially constant over the cross-sectional bending stress, which allows optimal material utilization.
  • the initial wedge or cutting angle ⁇ 2 when the cutting edge 07 enters the material roll 04 initially increases with increasing penetration depth into an obtuse angle ⁇ 1 to the round cross section.
  • the wedge angle ⁇ continuously increases along the cutting edge 07.
  • the material displacement is favored with increasing Mitauerquerites.
  • the sleeve material is first cut effectively at the point of penetration and without damaging further cardboard layers, see section B - B (FIG. 5) and correspondingly displaced with increasing depth of penetration of the cutting edge 07, see section C - C (FIG. 5).
  • the angle ⁇ 1 increases continuously to angle ⁇ 2 .
  • the penetration forces of the cutting edge 07 into the roll of material 04 minimize.
  • the driver elements 06 are attached to the mandrel 01 by means of a clamping ring 11 (see FIG. 2). At the cutting edge 07 opposite end of the driver 06 an annular flange 12 is provided, which secures the driver element 06 against slipping out of the clamping ring 11. In addition, two key surfaces 13 and 14 are worked on the driver element 06, in which a Assembly tool can be brought into engagement.
  • the driver elements pass through a designed in the manner of a lifting-Schaltrings 16 switching device 16 which is on the front side of the roll of material 04 can be brought to bear flat.
  • the switching device 16 is shown in each case in the clamping position, which it occupies after the uprights of the roll of material 04 on the mandrel 01.
  • the switching device 16 is mounted axially displaceable and is supported by a plurality of springs 17, z. B. coil springs 17 on the clamping ring 11 from.
  • the spring constant of the coil springs 17 is just chosen so large that the spring force is sufficient to strip the roll of material 04 when moving apart of the mandrels 01 of the driver elements 06. Ie. by adjusting the switching device 16 from the illustrated clamping position in the advanced ejection position, the roll of material 04 is brought out of positive engagement by the driver elements 06 and can be easily removed from the mandrel 01.
  • a contactlessly operating sensor 18 is provided on the mandrel 01, with which the position of the switching device 16 can be detected. This means in other words that it can be determined by evaluating the output signal of the sensor 18 in the system control, whether the switching device 16 is in its clamping position or in its Auswerfgna. By this signal evaluation can be detected in other words, whether a roll of material 04-10achst on the mandrel 01 or not.
  • a device for producing a driver element 06 is shown schematically.
  • a profile grinding wheel 19 By means of a profile grinding wheel 19, a first convex cutting surface 08 is worked on at the end of a profile bar in a first processing step.
  • the profile bar is doing at an acute angle ⁇ / 2, which is just half of the Wedge angle ⁇ corresponds, brought into engagement with the profile grinding wheel 19.
  • the profile rod is rotated by 180 ° and the processing is repeated analogously on the opposite side, whereby the second cutting surface 09 and the cutting edge 07 are formed.
  • Fig. 9 can be seen the convex circular profile 21 on the profile grinding wheel 19, whereby the production of cutting surfaces 08 and 09 is possible, which have the shape of a portion of a cylinder jacket surface.
