Definitions

• the invention relates to a device for winding a thread into coils according to the preamble of claim 1.
• the known device for winding a thread is used in particular in the production of glass threads.
• the threads are removed immediately during winding of a spinneret.
• the known device has two winding spindles, which are held by a winding turret.
• the winding turret is rotatably mounted in a machine frame and guides the winding spindles alternately into a winding area and a changing area.
• the winding area one or more threads are wound on the winding spindle simultaneously into coils.
• the finished wound coils can be removed from the winding spindle and replaced by winding tubes for receiving a new coil.
• the winding spindle arranged in the winding spindle is associated with a traversing device which guides the yarn back and forth in the axial direction of the spool.
• a first traversing movement is generated on the thread by the traversing device.
• this traversing movement is smaller in its stroke length than the predetermined coil width.
• the winding spindle is on the winding turret by a linear drive out and forth, so that the winding spindle performs a second traversing movement.
• Each of the winding spindles is thus coupled to a separate linear drive which axially displaces the winding spindle in the winding area.
• the winding spindles are driven by separate spool drives at a substantially constant peripheral speed. So far it is necessary that the traversing mechanism must cooperate with each of the linear drives for moving the winding spindle after each bobbin change. For this purpose, a renewed synchronization of the two traversing movements is required in each case before each start of winding.
• US Pat. No. 7,866,590 B2 discloses a device for winding a thread into packages, in which the traversing device is formed by a plurality of flyer wings arranged on a flyer shaft. By rotation of the flyer shaft, the yarn is slidably guided on the flyer wings in a reciprocating motion, so that thus a first traversing movement is performed. In order to obtain a required for the coil width storage width of the thread, the flyer shaft is guided axially back and forth by a linear drive.
• winding spindles are formed on the Spulrevolver so axially displaceable that each of the winding spindles can be coupled alternately in the Aufspul Scheme for performing the second traversing movement with the linear drive.
• the invention has the particular advantage that the linear drive can be formed stationary and can be combined directly with traversing device. This can also minimize the control effort when winding the thread.
• the distribution of the traversing movement between the traversing device and the winding spindle remains advantageous, so that the deflection of the thread by the traversing device is limited to a minimum stroke. Since the second traversing movement can be performed by one and the same linear drive despite changing winding spindle, the coils can be realized with substantially uniform Fadenablagen and crossing angles. The coils thus have on each winding spindle essentially an identical package density.
