Definitions

  • the invention relates to a winding device for winding or unwinding strips of any width according to the preamble of the main claim.
  • Strips or sheets of any material, such as edge banding or veneer sheets, are stored and transported in the form of rolls.
  • a cutting device is connected upstream, which cuts wide material webs into strips of any width.
  • the winding device according to the prior art has a drive shaft which carries a bearing shaft with a three-part circumferential surface.
  • the winding cores are slipped onto the three-part circumferential surface and, when the drive shaft rotates, the three parts forming the circumferential surface of the bearing shafts are pressed outwards, so that the cores are held in place.
  • guides are provided corresponding to the cut strip, which guide the strips between these two devices.
  • Separate spacers are arranged between the winding cores on the bearing shaft. If the strips to be wound have different thicknesses or are made of different materials, it can happen that during the winding process, in which the winding cores on the bearing shaft or drive shaft rotate at the same speed, some strips sag, while other strips are taut . This results in different winding hardnesses of the rolls and, despite the spacers, the individual strips may overlap. In addition, due to the spacers provided between the cores, a larger winding space is not used.
  • EP-A1-0 002 429 shows a known winding reel for the simultaneous winding of at least two strip strips, with a winding drum which can be driven via a shaft, the latter consisting of individual drum rings which are each rotatably mounted relative to the winding shaft and are connected to the shaft via a slip clutch the individual tape strips exist.
  • radially displaceable pressure rams are provided over the shaft circumference and the drum length, which press against the inner jacket of a drum ring. This is to achieve a constant strip tension for a good winding result.
  • the constant tensile stresses required for winding are applied by a separate braking mechanism for the tape strips.
  • a winding device is also described in US-A-4,431,142, in which, however, additionally driven deflection rollers are required as well as further additional backup rollers.
  • the winding mandrels also have to be pulled out of the rolls here, which is complex and cumbersome.
  • the clamping element used is a rotationally dependent, form-locking clamping element, which introduces the holding forces into the sleeve via two points. This means that malfunctions cannot be avoided because the susceptibility of the machine increases.
  • driver rings are arranged axially displaceably next to one another and rotatably mounted on a driver shaft.
  • Flange-like friction rings are located between the driver rings, which are also axially displaceable, but are arranged so that they cannot be adjusted with respect to the shaft.
  • the last ring, at the end of the shaft, is supported against a shoulder, while the end ring on the other side, which is distant, is spring-loaded.
  • the present invention which is based on the object of providing an improved winding device for winding or unwinding strips of any width, which is designed such that the strips are wound as unaffected by faults as possible with constant winding hardness with a simple device structure and can be handled at a constant train speed, whereby the available changing space should be fully usable.
  • the friction rings or friction disks at the same time form the receiving carrier for the winding core, that is to say the friction disc is a unit and carries out the different functions of applying a radial pressure and receiving the winding cores.
  • a bushing with a flange which is fixedly connected to the drive axle is advantageously provided, on which a tensioning ring slides, the flange pressing against an end face of the tensioning ring and applying the desired axial pressure.
  • the driver ring consisting of three segments is additionally arranged on the tension ring in such a way that it can easily stand out from the circumferential surface of the tension ring and clamps the winding cores.
  • the arrangement of the friction disks according to the invention is independent of the width of the winding cores and there is no need to make changes with regard to the carrier elements or friction elements or certain spacers.
  • the winding hardness is independent of the current diameter of the strip roll, the thickness and hardness or the flexibility of the material to be wound up and the strip width, whereby in addition, the winding hardness can be predetermined by the friction pressure.
  • a further advantage of the invention is that no additional device is required for loading or unloading the winding cores and that the winding axes do not have to be removed from the machine.
  • the winding cores can be easily placed and removed by hand on the receptacles or drive rings without any device.
  • the driver rings for the winding cores are self-tightening, which means that the latter do not have to be tensioned by a handle or additional measures and secured against loosening.
  • the bushing 1 consists of several parts: a bushing 2, a clamping ring 3 and a driving ring 7 consisting of three segments 4, 5, 6.
  • the bushing 2 is positively connected to a drive shaft 8 via a part 9 and consists of a cylindrical extension 10 and a flange 11.
  • Steel can preferably be selected as the material for the bushing.
  • the clamping ring 3 which has an annular recess 12 in an end face, sits on the cylindrical extension 10 in a clearance fit.
  • the socket 2 lies with its flange 11 in this recess 12, the end face of the flange 11 projecting somewhat beyond the outer end face of the clamping ring 3.
  • the clamping ring 3 is provided with a slot-like incision 13 in the center on its peripheral surface and also has three elongated openings 14 passing through the end faces.
  • the driving ring 7 with a T-shaped cross section is arranged on the peripheral surface of the clamping ring 3, one leg of the driving ring 7 engages in the incision 13 and is slidably guided therein.
  • the individual segments 4, 5, 6 of the driving ring 7 are held by pins 15 guided in the openings 14.
  • the elongated openings and the circle predetermined by the peripheral surface of the clamping ring 3 are not arranged concentrically, so that the segments 4, 5, 6 stand out from the peripheral surface of the clamping ring 3 when displaced in the openings 14.
  • Two arcuate incisions 16, 17 are arranged in the inner peripheral surface of the clamping ring 3.
  • the winding core 18, on which a strip is wound, is seated on the peripheral surface of the driving ring 7.
  • a large number of the friction disks 1 shown in FIGS. 1 and 2 are arranged side by side on the drive shaft 8 and clamped.
  • the flange 11 of the bushing 2 of a friction disk is pressed against the end face of the clamping ring 3 of the other friction disk.
  • the strips are wound onto the winding cores 18, wherein the winding core and strips can cover several friction disks 1. If during the winding-up process the tensile force on the strip is greater than the friction pressure, the clamping rings 3 assigned to the strip slip through on the bushes 2 until the tensile force becomes lower again and the clamping ring and bushing rotate with one another.
  • the strips to be wound onto the individual cores are stretched independently of one another and the parameters of one strip do not affect the others.
  • a constant winding hardness is thus achieved for all strips, this winding hardness being specifiable differently by changing the friction pressure. Since the strips are always taut, spacers and guides between the winding device and the cutting device can be omitted.
  • the winding device has been described in such a way that strips are wound up.
  • the winding device can also be used for unwinding strips, a constant pulling speed being specifiable by the special design of the friction disks or by the friction pressure.
