Definitions

  • the invention relates to a device for winding up material webs, consisting of at least one winding device, preferably of two winding devices which are offset by 180 degrees from one another on a central shaft, with holding mandrels which are rotatably mounted and aligned with one another in carriers which are axially adjustable relative to one another , which are intended for receiving winding sleeves clamped between them, each holding mandrel of each winding device is provided with a drive and the other freely rotatable on an axially displaceable pin, preferably on the piston rod of a pneumatic piston-cylinder unit, which is mounted between its the winding sleeve clamping position and its retracted position is movable by a distance which corresponds at least to the sum of the immersion depths of the two holding mandrels in the bores of the winding sleeves, and with one to the ge between the holding mandrels holding winding sleeve adjustable pressure roller.
  • a device of this type is known from US-PS 32 98 624. Since the immersion depths of the two holding mandrels in the bore of the winding sleeves must be relatively large in order to ensure that the winding sleeves are held well on the holding mandrels without damage To ensure damage or deformation leading to impermissibly high pressing forces or surface pressures, the extension length of the pin or the piston rod from the socket or cylinder holding this must also be relatively large. Because of the weight of the winding roller and in particular also because of the additional pressure force transmitted from the pressure roller to the winding roller, the pin or the piston rod in its holding position act considerably on these bending forces. So that the pin or the piston rod can absorb these forces without undue deflection, they must be made thick enough.
  • the length of the pressure roller In order to be able to wind winding cores of different lengths on the device, the length of the pressure roller must correspond to the greatest length of the winding cores to be wound. However, this means that the pressure roller protrudes beyond the bushing which supports the pin or the cylinder and its holding devices if the carriers of the holding mandrels for winding shorter winding cores are moved closer together, that is to say they have a smaller axial distance from one another.
  • the pressure roller covers the devices holding the pin or the piston rod, only winding cores can be wound whose radius is greater than the distance between the center line of the pin or the piston rod and the outer edge of the devices holding and supporting them.
  • this distance is relatively large because of the required thickness of the displaceable pin or the piston rod, shorter winding sleeves of smaller diameter cannot be wound with the known device at all or only if the pressure roller is also replaced and replaced by a shorter one, which is the shorter length of the to winding winding sleeve of smaller diameter is adapted.
  • the object of the invention is therefore to provide a device of the type mentioned with which winding sleeves of smaller diameter can also be wound with material webs without exchanging the pressure roller when the carriers carrying the mandrels are moved so far together that the pressure roller which moves the movable pin or covers the piston rod holding devices.
  • this object is achieved in a device of the generic type in that the freely rotatable holding mandrel is mounted eccentrically to the pin on a support piece connected to the displaceable pin in the direction of the pressure roller.
  • the freely rotatable holding mandrel is thus mounted eccentrically offset outwards on the pin so that the pin itself can be made in the required thickness without the adjustability of the pressure roller on winding sleeves of smaller diameter being impaired when this and displacement devices of the pin covers.
  • a central shaft 2 is rotatably supported in a manner not shown.
  • a circular disc and an annular housing 4 are mutually adjustable and lockable.
  • a pulley 5 which can be driven by a motor, not shown, is mounted on which a pinion 6 is placed.
  • This pinion 6 meshes with an intermediate wheel 7, which in turn engages in the toothing 8 of a shaft 9 which projects from the housing 4 at one end.
  • a clamping head 11 is fixed, on which the winding tubes 12 can be fixed by means of clamping elements 13.
  • the function of the tensioning elements 13 is known and will not be explained in more detail here.
  • the circular disc 3 opposite the housing 4 also has two diametrically opposite winding points, one of which is shown. From the drawing it can be seen that the winding point consists of a cylinder 14 fixedly connected to the disc 3, in which a piston 15 is mounted.
  • the piston rod 16 associated with this piston 15 is hollow.
  • a rod 18 protrudes into the cavity 17 of this piston rod 16 and is firmly connected to the bottom 19 of the cylinder 14. That in the cavity 17th protruding end of the rod 18 is fixedly connected to a stop disc 20, on which a spring 21, which surrounds the rod 18 in regions, is supported at one end.
  • the other end of the spring 21 is supported on a snap ring 22 which is mounted in a groove in the piston 15.
  • the spring 21 therefore tries to always retract the piston rod.
  • a compressed air line 23 is provided which opens into the rear end of the cylinder space 24.
  • a support plate 25 is fixedly connected to the end of the piston rod 16 protruding from the cylinder, to which a pin 26 is attached, offset to the outside of the piston rod 16.
  • a hollow mandrel 27 for the winding tubes 12 is freely rotatably supported on this pin.
  • the piston rod 16 has a longitudinal groove 29 into which a feather key 30 engages, which is mounted in the disk 3. In this way, the piston rod 16 is secured against rotation.
  • the piston rod 16 can be designed to be correspondingly large in accordance with the load acting on it during the winding process and due to the contact pressure of the roller 28.
