Definitions

  • the invention relates to a method for determining a monitoring speed ("safe envelope speed") for a winding reel of a winding machine for winding a winding material on the winding of the winding material with a Wickelspulenist loftiere rotating reel, wherein the reel spool is preceded by a feed, so that when winding the winding material the winding spool can be supplied via the supply spool rotating at a feed spool speed.

  • Winding machines are well known and serve for winding winding material, such as fibers or threads.
  • EP 0 183 935 describes, for example, a winding machine with a drive whose speed is limited by a signal that defines a maximum speed.
  • Such a winding machine has a variable or (controllable / adjustable) adjustable speed, i. Wickelspulenist loftiere, drivable winding reel, on which the winding material during the winding process (during operation of the winding machine) is wound.
  • the winding material is withdrawn during the winding process, the winding material, the supply spool usually once in a row several times, wraps around, fed to the reel spool and wound onto the reel spool.
  • the invention has for its object to provide a simple and cost-effective monitoring of a winding machine against possible mechanical damage to a reel spool of the winding machine during winding or during operation of the winding machine.
  • the object is achieved by a method for determining a monitoring speed ("safe envelope speed") for a winding reel of a winding machine for winding a winding material on the wound during winding of the winding material with a Wickelspulenist loftiere winding reel, a control unit for such a winding machine and such a winding machine with the features solved according to the respective independent claim.
  • winding bobbin diameter or radius in the following only winding bobbin diameter or radius, is the actual, physical (total) dimension, i. Diameter or radius, the winding spool understood, which is composed of the diameter or the radius of the empty / unwound winding spool and the related physical dimensions of the coil.
  • variable "safe” limit speeds can be represented by or depending on the winding spool diameter / radius, which is referred to as the speed envelope. Accordingly, the variable "safe” limit speeds are referred to as "safe" envelope speeds.
  • the speed envelope thus defines the - winding coil diameter / radius dependent - speed limit, which is the "safe" operation of the winding / winding reel (Wickelspulenist loftbaum at a certain winding reel diameter / radius below the associated envelope speed) delimits the "hazardous" operation of the reel / reel spool (reel spool speed at a particular reel spool diameter / radius above the associated envelope speed).
  • the reel spool speed may be reduced to a speed lower than the envelope speed, thus restoring operation of the reel into the reel "safe area” to bring, ie to move the winding machine back into the "safe area”.
  • the winding coil thickness or the winding coil diameter / radius during the winding process can be detected.
  • the invention is thus based on a winding machine for winding a winding material on a winding coil rotating during winding of the winding material with a Wickelspulenist loftiere.
  • the winding material may be a fiber, in particular a natural fiber, a vegetable fiber, a mineral fiber, a synthetic fiber, a synthetic polymer fiber or an industrially produced inorganic fiber, or a thread, in particular a glass thread.
  • the winding bobbin is preceded by a feed bobbin of the winding machine, so that during winding the winding material of the winding bobbin can be fed via the feed bobbin rotating at a feed bobbin rotational speed.
  • fed via the supply reel means that the winding material is not wound up on the supply reel (connected to a changing winding thickness or feed reel radius / diameter), as in the reel spool, but that the winding material, for example by a single wrap the supply spool, passes over the spool (connected to fixed or constant feed spool diameter / radius or fixed / constant "winding thickness” (wrap) on the feed spool).
