Definitions

  • the invention relates to a method according to the preamble of Claim 1 and a device for performing the Procedure.
  • DE-GM 74 37 800 and DE 23 28 828 C2 concern the Forming a thread reserve on winding spools with the help of a reciprocable auxiliary thread guide.
  • the auxiliary thread guide can be swiveled, lifts the thread when swung up the thread guide carrying out a traversing movement and can outside the traversing area of the thread guide desired reserve windings or waste windings form on the sleeve of the coil.
  • By swiveling the Auxiliary thread guide gets the thread back into the Detection area of the thread guide is by the thread guide whose traversing movement is captured again and continues to one Cheese wound.
  • Fadens is not coordinated with the movement of the thread guide as the thread on for a while held in the same place of the coil and in a larger number of turns can be placed one on top of the other. The one there resulting beads can cause difficulties when unwinding the Lead packages.
  • Thread guides and thread transmitters are not correcting the problem.
  • Thread guides are at risk of the aforementioned disadvantages undesirable shifting of the thread over the bobbin edge out.
  • the invention has for its object the known Method and devices for transferring the thread to be wound to a reciprocating traversing thread guide improve.
  • this object is achieved by a method with the Features of claim 1 and by a device with the Features of claim 6 solved.
  • the thread is preferably lowered and picked up, after the drive of the cheese has started and a short period of time t since the cheese began to rotate has expired.
  • lowering and picking up of the thread advantageously take place when a predetermined Number of revolutions of a cheese driving the cheese Friction roller is reached. This allows the number of Windings that are at a standstill of the Traversing thread guide are wound up, extraordinarily keep low. Beads that cause difficulty in unwinding the Cross bobbins could be avoided.
  • the auxiliary thread guide is preferably between the operative position and the rest position can be pivoted. This allows the Space requirements can be reduced to a minimum by using the Swivel shaft of the auxiliary thread guide in a very small Distance from the traversing thread guide can be while on the other hand to pivot the auxiliary thread guide to Example a simple crank system of any kind is sufficient.
  • the auxiliary thread guide can in particular be fixed to a shaft be attached which by means of a pneumatic cylinder back and forth is pivotable here, the pneumatic cylinder being pivotable is mounted and engages the shaft via a swivel lever. The swivel movement is controlled by a control device triggered.
  • the moving mass kept very low and the change from the Active position in the rest position of the auxiliary thread guide be carried out extremely quickly.
  • the time for an alignment of the thread in the starting position, the lowering and the thread is picked up by the traversing thread guide required, can be kept extremely short. In such an extremely short period of time t only a few Turns, for example one to three turns, stored that no beads by winding the thread on a Place the cheese arise, causing difficulties with Unwind could result.
  • the auxiliary thread guide is advantageous in the direction of Traversing thread guide pivotable into its rest position. Next an extremely small footprint and practically none Disability at the winding unit must for such Swivel movement only a very small swivel angle be overcome. In addition, the pivotal movement by the Thread tension supported. This allows the time t advantageously keep it short.
  • the invention enables a simple and safe
  • the thread is picked up by the traversing thread guide after a Thread interruption without the purchase of disadvantageous beads must be taken.
  • Figures 1 and 2 show one in a usual pivotable bobbin frame A mounted bobbin 1, the by means of a conventional friction drive roller 2 for winding of the thread 3 is set in rotation.
  • a conventional friction drive roller 2 can also use the cheese 1 a single motor drive, not shown in Rotation are offset, the cheese 1 then in is supported in a known manner 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 thread guide 5 for a reciprocating movement driven.
  • the traversing thread guide 5 is driven by a motor 13 via a reciprocating toothed belt 12 emotional.
  • the motor 13 and thus the traversing movement and Positioning of the traversing thread guide 5 is carried out by a Figure 3 shown encoder 20 monitored and by a so connected control device 14 controlled.
  • FIG. 1 and 2 there is a Auxiliary thread guide 4 in an active position and has the Thread 3 detected.
  • the thread 3 is thereby from Traversing thread guide 5 excavated.
  • the Thread 3 is also raised relative to its winding position so that it the provided in the embodiment of Figures 1 and 2 Thread guide bracket 6, the so-called storage bracket, no longer touched.
  • To pivot the auxiliary thread guide 4 between the Rest position 4 'and the active position is used on the schematically indicated machine frame B articulated Pneumatic cylinder 7, alternatively with lines 8 and 9 Compressed air from a compressed air source 17 can be acted upon.
  • the Compressed air is applied to lines 8 or 9 with With the help of a valve 18 and a relay 19 by the Control device 14 is actuated.
  • the pneumatic cylinder 7 drives a pivot lever 10, which for pivoting one Shaft 11 is used, which is firmly connected to the auxiliary thread guide 4 is.
  • the auxiliary thread guide 4 has one on the Traversing area of the traversing thread guide 5, upper Thread leading edge 4.1, one on both sides towards the middle the traversing stroke of the traversing thread guide 5 sloping contour has, that is, the thread leading edge 4.1 is towards the center lowered. With a thread break, such as one Thread break, the auxiliary thread guide 4 is in the active position pivoted.
  • the thread 3 is lowered after the thread 3 has tightened.
  • the lowering can be effected by the control device 14 after the time t, which is dimensioned long enough to ensure a tightening of the thread, or alternatively after a predetermined number of revolutions of the Friction drive roller 2.
  • the number of rotations and the angular position of the friction drive roller 2 is detected by a displacement sensor 16 and by the Control device 14 evaluated.
  • Another alternative, not shown for reasons of simplification, is to measure the thread tension building up, for example with a conventional thread tension sensor, and to trigger the lowering of the thread 3 after the thread tension measured and evaluated by the control device 14 has reached a predetermined value.
  • the invention is not based on the illustrated Embodiment limited.
  • the Auxiliary thread guide 4 can alternatively be designed as a wire bracket.
  • the control device 14 can be via unspecified Lines with other elements of the job, the Textile machine or other control devices for Example computers.
