Definitions

  • the invention relates to a method according to the preamble of Patent claim 1 and an apparatus for carrying out the Process.
  • DE-GM 74 37 800 and DE 23 28 828 C2 relate to Forming a thread reserve on take-up reels with the help of a reciprocable auxiliary thread guide.
  • the auxiliary thread guide is pivotable, lifts the thread when swiveling up the yarn traversing a traversing movement and can outside the traversing range of the yarn guide the desired reserve windings or waste windings on the sleeve of the coil.
  • the thread returns to the Detection area of the thread guide, is supported by the thread guide whose traversing movement detected again and continue to one Cheese wrapped.
  • the thread to the thread guide the winding unit are only very limited or not at all suitable.
  • the delivery of the Thread does not take place in this respect in coordination with the movement the thread guide as the thread for a while on and held in the same place of the coil and in a larger number can be stored on turns of turns. The case arising bulges can lead to difficulties in unwinding the Lead cheeses.
  • Winding conical cheeses is after a bobbin change or after a yarn break the yarn to be wound first held by an auxiliary thread guide and after release from Yarn guide then taken when this is in the running direction to the small bobbin diameter is in motion.
  • the Lifting and lowering the auxiliary thread guide by means of a elaborate, several swivel levers comprehensive Actuating mechanism.
  • the bow-shaped auxiliary yarn guide and the actuating mechanism are in particular vertical Direction relatively space-consuming trained and can with it the front of the spinning station be disturbing what the Applications of this system considerably limited.
  • US-A-5 348 242 relates to a cutting device for a on a cheese winding up thread.
  • the thread performs a traversing movement.
  • the Cutting device has a thread lifting device, the between below and above the traversing triangle Positions is movable as well as one below the level of the Traversing triangle located knife.
  • the thread lifting device is performed prior to the completion of the coil travel Interruption of the running thread actuated. This is the Thread lifter from its located under the traversing triangle Rest position moved to an upper position. The thread gets while in a thread catcher of the thread lifter and is from the Level of traversing triangle lifted.
  • the invention is based on the object, the known Method and devices for transferring the wound up Thread to a reciprocating traverse guide to improve.
  • the lowering and the absorption of the thread advantageously take place when a given Number of revolutions of a cheese driving the cheese Friction roller is reached. This can be the number of Turns that occur during the stoppage of the Changierfaden projects be wrapped, extraordinary keep low. Bulges that cause difficulty in unwinding the Cross coils could be avoided.
  • the auxiliary yarn guide is preferably between the operative position and the rest position pivoted. This allows the Space requirements are reduced to a minimum by the Swivel shaft of the auxiliary thread guide in a very small Distance from the traversing guide can lie while on the other hand for pivoting the auxiliary yarn guide to Example a simple crank system of any kind is sufficient.
  • the auxiliary yarn guide can in particular firmly on a shaft be attached, the means of a pneumatic cylinder and is pivotable ago, the pneumatic cylinder is pivotable is mounted and attacks via a pivot lever on the shaft. The pivoting movement is controlled by a control device triggered.
  • the device can to moving mass kept very low and the change of the Active position in the rest position of the auxiliary yarn guide be carried out extremely quickly.
  • the time for aligning the thread in the starting position, lowering and the inclusion of the thread by the traversing yarn guide is required, can be extremely short.
  • Such an extremely short time span t will be only a few Windings, for example, one to three turns, filed, so that no beads by winding the thread on one Place of the cheese develop, which causes difficulties in Can cause unwinding.
  • the auxiliary thread guide is advantageous in the direction of Changierfaden concernss pivoted to its rest position. Next an extremely small footprint and virtually none Disability at the winding unit must be for such Pivoting movement only a very small swivel angle be overcome. In addition, the pivoting movement is due to the Thread tension supported. This allows the time t advantageous to keep short.
  • the invention enables in a simple manner a safe Take the thread through the traversing yarn guide after a Thread interruption without disadvantageous beads in purchase must be taken.
  • Figures 1 and 2 show one in a conventional pivotable creel A stored cheese 1, the by means of a conventional friction drive roller 2 for winding of the thread 3 is set in rotation.
  • the cheese 1 also by means a not shown single motor drive in Rotation are offset, the cheese 1 then in known manner is supported on a support roller. While the proper winding of a thread becomes this by means of the driven in the direction of the double arrow f Traversing yarn guide 5 to a reciprocating motion driven.
  • the traversing yarn guide 5 is from a motor 13th via a toothed belt 12 driven in a reciprocating manner emotional.
  • the motor 13 and thus the traversing movement and the Positioning of the traversing yarn guide 5 is by a in Figure 3 shown encoder 20 and monitored by a so controlled control device 14 controlled.
  • FIG. 1 and 2 is a Auxiliary thread guide 4 in an operative position and has the Thread 3 detected.
  • the thread 3 is characterized from the Traverse thread guide 5 raised. In this position is the Thread 3 compared to its winding position also raised so that he provided in the embodiment of Figures 1 and 2 Thread guide bar 6, the so-called storage bar, not more touched.
  • For pivoting the auxiliary yarn guide 4 between the Rest position 4 'and the active position is used at the schematically indicated machine frame B hinged Pneumatic cylinder 7, via lines 8 and 9 alternatively with Compressed air from a compressed air source 17 can be acted upon.
  • the Applying the lines 8 or 9 with compressed air takes place with Help a valve 18 and a relay 19, the of the Control device 14 is actuated.
  • the pneumatic cylinder 7 drives a pivot lever 10, which is used to pivot a Shaft 11 is used, which is firmly connected to the auxiliary yarn guide 4 is.
  • the auxiliary yarn guide 4 has a over the Traversing range of the traversing yarn guide 5 extending upper Thread guide edge 4.1 on, one from both sides to the center the traverse stroke of the traversing yarn guide 5 sloping contour has, that is, the thread guide edge 4.1 is towards the center lowered.
  • a thread break such as a Thread breakage, the auxiliary thread guide 4 is in the operative position pivoted.
  • the lowering of the thread 3 takes place after the thread 3 has streamlined.
  • the lowering can be done by the Control device 14 effected after the expiration of the time t which is sufficiently long to tighten of the thread, or alternatively after one given number of revolutions of the Friction drive roller 2.
  • the number of revolutions and the Winkei ein the Fritationsantriebswalze 2 is from a displacement sensor 16 and detected by the Control device 14 evaluated.
  • Another alternative, not shown for reasons of simplification possibility is, for example, the building up thread tension to measure with a standard yarn tension sensor and that Lowering the thread 3 trigger after the measured and from the control device 14 evaluated thread tension a has reached predetermined value.
  • the invention is not limited to that shown Embodiment limited.
  • the Auxiliary yarn guide 4 may be alternatively formed as a wire hanger.
  • the control device 14 may have unspecified Lines with other elements of the job, the Textile machine or other control devices, for Example computers, be connected.
