Definitions

  • the invention relates to a workstation of a winding machine according to the preamble of claim 1.
  • bobbins preferably spinning rings manufactured on ring spinning machines, which contain relatively few yarn volumes, are wound into large-volume cheeses.
  • the yarn is also monitored for yarn defects, with yarn failures being cut out and replaced with nearly yarn-like yarn splices.
  • winding speeds with which such, so-called cross-winding machines work are limited to generally less than 2000 m / min due to various physical conditions, in particular by the thread tensile forces occurring during the rewinding.
  • the thread tension can in the course of a Kopsorii, if no effective countermeasures are taken to increase to a multiple of the initial yarn tension, which significantly increases the risk of thread breaks.
  • Such a device for limiting the increasing in the course of Kopsumble yarn tension is for example in the CH-PS 669 177 described.
  • this device is initially wound with a relatively high winding speed at the beginning of Kopsappel, however, the winding speed at the end of Kopsappel lowered to an uncritical level.
  • Such a rotatably mounted spool receiving mandrel for a supply spool is for example in the CH-PS 542 781 described in connection with a precision spooling machine.
  • the bobbin receiving mandrel is connected via a drive belt with a drive drum in connection, which is mounted on a machine-length, constantly rotating drive shaft and can be selectively connected via an electromagnetic clutch to the drive shaft.
  • a corresponding device ensures that the Spool receiving mandrel of the supply spool is rotated counter to the unwinding direction of the thread.
  • the differences in speed can be up to 40%, depending on the respective laying angle of the thread on the cross-wound bobbin.
  • the winding speeds are about one order of magnitude below the winding speeds of winding machines when rewinding supply bobbins.
  • the winding units are each equipped with a arranged above a feed bobbin thread take-off device and a downstream device for temporarily receiving a significant amount of thread to allow, for example, connecting two yarn ends, without the need for an interruption of the rewinding is necessary.
  • the winding units When in the DE-OS 20 18 375 described device for controlling the yarn feed into a storage container, the winding units each have a thread withdrawal device, which deducts the thread at a speed which is 10 - 30% above the winding speed of the winding device, from the supply spool.
  • the withdrawn from the feed bobbin thread runs on its way to the reservoir, monitored by sensors, to an injector that conveys the thread in the reservoir, the filling state is also monitored and supplemented as needed.
  • the winding units in the DE-AS 22 15 003 Described winding machine each have a thread withdrawal device, a rotatably mounted, equipped with a brush-like surface thread storage device and a drive drum for frictional driving a package. All thread handling devices of the winding unit are acted upon by a common drive source.
  • the US 3908920 essentially refers to winding machines, in which several threads are supplied with glucher thread tension.
  • the present invention seeks to improve the winding machines of the aforementioned type, that is to optimize the jobs of such winder to the effect that the jobs can work with a much higher winding speed, without thereby significantly reducing the risk of yarn breaks increases.
  • the removal of the thread from the spinning cop and the winding of the cheese on the winding device are so separated that the removal of the thread from the spinning cop is not affected by the traversing of the thread during the manufacture of the cheese.
  • the thread is withdrawn by a thread withdrawal device with irrespective of irresistible fluctuation speed of the spinning cop and goes through on his way to the cheese a thread store, on the one hand ensures that when winding the cheese, that is, in the traversing of the thread running on the cheese, always sufficient thread length is available and on the other hand prevents that caused by the traversing of the thread fluctuations in the thread speed negatively affect the thread take-off at the spinning cop.
  • the thread store essentially only has to absorb a quantity of thread which is adapted to the thread changing due to the Fadenchangleiter thread, the storage volume is uncritical to manage, which is particularly important at the high winding speeds of importance.
  • the device according to the invention therefore not only leads to an improvement in the efficiency of the winder, but also to an increase in quality of the manufactured cheeses.
  • the yarn store is assigned in an advantageous embodiment, a sensor device which is connected to a winding station computer.
  • a the Spulstellenrechner and the drive of the thread withdrawal device einumbleder control loop is present, which controls the thread withdrawal device so that in the thread store is always stored within predeterminable tolerance limits amount of thread is stored.
  • the thread store always stores such a thread amount that a compensation of the amount of thread required by the Fadenchangmaschine is reliably ensured.
  • the thread store is arranged in the thread running direction immediately before an upper thread guide, which forms the starting point for the traversing triangle of the thread.
  • the thread store is designed as a pneumatically acted thread store.
  • Such pneumatic thread storage are inexpensive to implement and allow, as long as a certain amount of thread is not exceeded, safe and easy storage of a running thread.
  • a mechanically operating thread store is possible instead of a pneumatically acted thread store (claim 6).
  • Such mechanically operating thread stores have the advantage that they can safely store even larger amounts of thread, which can offer advantages, for example, in the production of conical cheeses.
  • a thread cleaner arranged, which scans the running in this area at a uniform speed thread on irregularities and if necessary initiated a thread cutting device.
  • the measurement results of the thread cleaner are always very precise, especially as far as the length of the defects is concerned.
  • the winding units also have a drive means for rotating the spinning cop in the unwinding position and a further, second yarn store.
  • the drive device for the spinning cop as well as the thread withdrawal device are, for example, driven by a single motor, driven so that the thread is removed from the spinning cop with a predeterminable, uniform take-off speed.
  • the second yarn store which is connected between the spinning cop and the yarn draw-off device, compensates for variations in the amount of yarn that arise, for example, during unwinding of a spinning cop due to its cop winding, reliably.
  • the thread cleaner is preferably either immediately before or directly behind the thread withdrawal device, but always positioned in front of the first thread store.
  • the spinning cop is advantageously positioned during the unwinding in a vertical or nearly vertical position.
  • the thread is removed from the thread withdrawal device via the head from the supply spool.
