Definitions

  • the invention relates to a tensioning and guiding device for winding cores, in particular for machines for winding or unwinding paper or cardboard webs according to the preamble of claim 1.
  • a large number of clamping devices for winding cores which have a clamping part which sits on a shaft journal which is concentrically connected to a drive or brake shaft and which expands radially in order to clamp the winding sleeve radially in the event of a circumferential relative movement to the shaft journal.
  • a generic tensioning device is e.g. in EP-C 0 208 832.
  • the known tensioning devices for holding and guiding the winding rolls on their winding cores are well suited, provided the torque to be transmitted (braking or accelerating the roll) also increases with increasing roll weight.
  • the high roll weight e.g. three tons
  • the invention has for its object to provide a generic device that ensures secure centering and guidance of the winding tube with little wear even when no torque is applied.
  • the tensioning part merely takes over the function of torque transmission.
  • the weight of the winding rolls is carried by the smooth, cylindrical guide head, which also takes over the centering and guiding of the winding roll.
  • the tensioning and guiding devices according to the invention are also particularly suitable for directly measuring the rotational speed of the winding rollers if no torque acts . Even if one of the torque transmitting elements fails, the guidance and centering function is fully available.
  • claims 3 and 4 contain structurally less complex embodiments with maintenance-free, low-wear parts. These embodiments are also self-sealing, so that no dust can enter from the outside.
  • the embodiment according to claim 5 has the advantage that the winding sleeve is not displaced eccentrically to the axis of rotation of the guide head during tensioning. The outer surface of the tensioning part is pushed back by the weight of the winding roll without the tensioning force for torque transmission being lost.
  • Clamping devices are e.g. In the case of back-up roll rolling machines for winding paper or cardboard webs onto winding tubes in the winding slides of the individual winding stations.
  • the tensioning device has a shaft 1 that can be coupled to a drive, the mounting 2 of which is fastened in a winding carriage (not shown) of a winding station.
  • a shaft journal 3 is fixedly and concentrically connected to the drive shaft 1, which is partially supported in the winding carriage 4 and on which a flange-like stop 5 for the winding sleeves 6 is attached at a short distance from the boundary wall of the winding carriage 4.
  • the end of the shaft journal 3 adjoining the stop 5 serves as a guide head 7 for the sleeves 6.
  • the guide head 7 has a smooth surface and its diameter corresponds to the inside diameter of the sleeve 6, in the present example approx. 76 mm.
  • a cylindrical pin 8 is fastened eccentrically by approximately 3 mm, the diameter of which is approximately half of the guide head diameter.
  • a hollow cylindrical clamping part 10 On the pin 8 sits above a bearing bush 9 a hollow cylindrical clamping part 10, the inner bore of which has a circular cross section and is also arranged eccentrically in accordance with the eccentricity of the pin, so that in one position (basic position) the lateral surface is concentric with the lateral surface of the guide head.
  • the outer diameter of the clamping part 10 is approximately 0.1 mm larger than that of the guide head 7, so that when a sleeve 6 is slid on, a positive connection is formed between the corrugated surface of the clamping part 10 and the inner surface of the sleeve.
  • a washer 11 which is screwed onto the end of the pin 8 and has a slightly smaller diameter than the outer diameter of the clamping part 10 secures it against axial displacement.
  • the clamping part 10 is designed to be somewhat radially compressible.
  • the clamping part 10 consists of two annular parts 10.1, 10.2, which are arranged concentrically one above the other and are connected to one another in a rotationally fixed manner, between which there is an elastic layer 10.3.
  • the elastic layer 10.3 is formed by rubber O-rings arranged side by side, which allow elastic displacement of the outer part 10.1 in the direction of the inner part 10.2 within limits.
  • a clamping part can be used that is made entirely or partially - for example in the outer area - from a limited elastic material.
  • a pin 12 is attached to the front side of the guide head 7 at a distance parallel to the axis of rotation and extends into a guide groove 13 in the clamping part 10.
  • the guide groove 13 runs along a circular arc concentric to the pin 8. At both ends it extends circumferentially to a less deep groove 14, in each of which a coil spring 15 is inserted.
  • the coil springs 15 press the tensioning part 10 into the basic position explained above when no torque is acting. However, their spring constant is chosen so low that they do not offer any great resistance to the rotational forces that occur.
  • the ratio of the axial lengths of guide head 7 and clamping part 10 to one another is greater than 1: 1, in the present example it is somewhat greater than 2: 1.
  • the springs 15 press the clamping part 10 into a position concentric with the guide head 7, so that the sleeves 6 form-fit when pushed onto the clamping device 10 with the entire circumference of the clamping part 10.
  • this is pressed outwards due to the eccentric bearing, so that the sleeve 6 is clamped between the outwardly pressed outer surface of the part 10.1 and the opposite circumferential part of the guide head 7.
  • An eccentric displacement of the sleeve 6 does not take place, since the layer 10.3 of the clamping part 10 is compressed against its elastic counterforce.
  • the clamping force for torque transmission is retained.
  • a torque transmission from the shaft journal 8 to the clamping part 10 takes place since this is clamped on the journal 8 due to the eccentricity.
  • a tensioning device according to the invention is also particularly suitable for online measurement of the rotational speed of a winding roller.
  • the speed of rotation of a winding roll can thus be directly on the Wave 1 can be determined without errors, without the need for complex corrections - for example, by measuring labels stuck on the sleeves. Therefore, the clamping devices according to the invention can also be used very advantageously in rolling machines in which no additional torque is applied via the shaft 1, for. B. in roller winding machines.
  • tensioning device seals itself and is therefore insensitive to dust.
