Definitions

  • the present invention relates to a winder according to the preamble of claim 1 or claim 20, a turret unit for a winder according to the preamble of claim 15 and a method for operating a winder according to the preamble of claim 19.
  • Such winder are mainly used in production lines in which an extruder produces an endless plastic film which is to be wound continuously and without interruption on hubs.
  • the recipe and the production speed and the width of the plastic film to be wound have a large variety of parameters.
  • the recipe entails that the film must be wound under well-defined conditions: for example, the tension in the wound film and the contact pressure during winding must be kept within a minimum tolerance range and the winding progress accordingly, otherwise the finished roll unusable.
  • Feed speeds of 500 to 600 m / min are the norm, 800 m / min attainable and even higher feed speeds are to be expected.
  • Winding diameters up to 400 mm are produced today, larger diameters are to be expected. The time for the winding of large diameters is one minute, of course, a shortening of this time is desirable.
  • the time available for the rotation of the turret assembly which ultimately is unproductive, is extremely short and should not exceed one second.
  • the weight of the finished rolls is considerable, for example, a multiple use with four coils with a diameter of 400 mm and a width of 500 mm about 224 kg.
  • the turret unit becomes a large, solid construction, which requires a very high drive power with correspondingly massive drive mechanisms for the rotation to be carried out in seconds.
  • each winding shaft is associated with a wegklappbarer tailstock, which engages via a retractable mandrel axially into the end face of the winding shaft and this so removably stored.

  • the winding 18 in 10 o'clock - or 14 o'clock - position taken with the result that the conveyor belt driven from a laterally parked position first under the winding must be, which costs additional time.
  • the lateral parking position is unavoidable, otherwise the conveyor belt would be in the way of rotation of the turret unit.
  • the conveyor belt 20 is already in position, since it does not stand in the way in the 6 o'clock position of the rotation of the turret unit. The loss of time is therefore limited to the short time required for the conveyor to start up.
  • a winder for an endless web of a plastic film with a revolving unit which is rotatable about its axis and has at least two winding shafts running parallel to its axis, is then loaded onto the winding cores, then finally wound with the film into a winding finished winding of this can be removed again, wherein on both sides of the turret bearing assemblies are arranged, in which the winding shafts are mounted at their respective ends in this, and wherein the storage for one end of the winding shafts is detachably formed, such that the respective Winding shaft can be loaded and unloaded from this end with dissolved storage, wherein the winder is designed such that each brought a winding shaft in the range of 6 o'clock position and the winding can be removed in this area.
