Definitions

  • the present invention relates to a method for operating a textile machine, which is used to produce roving, wherein during normal operation at least one consolidation agent of the textile machine is fed a fiber structure, wherein a roving having a protective twist is produced from the fiber structure with the aid of the consolidation agent, the Roving after leaving the setting agent and with the aid of a winding device downstream of the setting agent in a transport direction of the roving is wound onto a sleeve, and with the aid of sensors it is monitored whether a roving is produced by the setting agent and / or whether that produced by the setting agent Roving is wound onto the sleeve.
  • a textile machine for producing roving with at least one strengthening agent is proposed, with the help of which a roving having a protective twist can be produced during normal operation from a fiber structure supplied to the strengthening agent.
  • the textile machine has a winding device arranged downstream of the consolidation agent in a transport direction of the roving for winding the roving produced by the consolidation agent onto a sleeve and a sleeve changing device, with the aid of which a sleeve which has been wound by the winding device can be replaced by an empty sleeve.
  • the textile machine has an arrangement with the aid of which a starting process can be carried out, in which roving produced by the setting agent after it has been started up is brought into contact with an empty tube located in the region of the winding device and then wound up.
  • the textile machine comprises a sensor system which is designed to monitor whether a roving is produced from the strengthening agent and / or whether the roving is wound onto the sleeve.
  • Roving is made from mostly pre-treated (e.g. duplicated) slivers and serves as a template for the subsequent spinning process which the individual fibers of the roving are spun into a yarn, for example with the aid of a ring spinning machine.
  • pre-treated e.g. duplicated
  • a drafting device which is usually part of the corresponding roving machine, and then to provide a protective twist.
  • the stated strength is important in order to prevent the roving from tearing when it is wound up on a tube or while it is being fed to the downstream spinning machine.
  • the protective rotation given must be strong enough to ensure that the individual fibers are held together during the individual winding and unwinding processes and corresponding transport processes between the respective machine types.
  • the protective twist it must be ensured that the roving can be processed further in a spinning machine - the roving must therefore continue to be able to be warped.
  • flyers are primarily used, but their delivery speed is limited due to centrifugal forces that occur. There have therefore already been numerous suggestions for bypassing the flyer or replacing it with an alternative type of machine.
  • Another method for roving is in the DE 24 47 715 A1 disclosed.
  • the consolidation of the unconsolidated fiber structure described there takes place with the aid of a strengthening agent that does not twist, but rather spirally wraps around a fiber band through one or more filament yarns, preferably monofilament filament yarns. causes that hold the fiber structure together and give it its strength.
  • the spirals of the individual filament yarns can be arranged in the same direction or in opposite directions.
  • Two filament yarns are preferred, which are arranged in opposite rotation or intersecting.
  • the roving produced in this way is thus essentially composed of a sliver of parallelized staple fibers and one or more fine-titer filament yarns wrapping around the sliver in a spiral.
  • the filament yarn can be applied to small spools of small diameter.
  • the filament yarn is then withdrawn from the fixed bobbin and pulled together with the fiber assembly through the bobbin axis, the filament yarn being wound around the filament yarn and the number of windings drawn off the bobbin corresponding to the number of turns applied to the fiber assembly.
  • the strengthening means in such a way that only the unconsolidated fiber structure is guided through the spool axis in order to thereby lay the winding process behind the filament yarn spool.
  • the winding point should be determined by a suitable thread guide.
  • Another process for the production of roving describes the WO 2009/086646 A1 , the method comprising the following steps: 1) providing a fiber structure in the form of two, preferably untwisted, fiber bands, 2) issuing S and Z twists over alternating regions of the two fiber bands, regions of S and Z twists are separated on the respective sliver by areas without rotation, 3) bringing together the two slivers provided with S and Z twists to form a roving, the two slivers twisting automatically due to their tendency to turn back.
  • the S and Z rotations can e.g. B. are generated by means of two elements of the solidifying agent used, which hold the respective sliver by clamping, with at least one element, preferably both elements, of the sliver by means of a relative movement on its surface transversely to the longitudinal direction of the sliver alternately on both sides to give opposite turns. At the same time, the respective sliver is moved in the sliver direction.
  • the S and Z rotations can also be generated using an aerodynamic, in particular pneumatic, method.
  • the alternating S and Z rotations are also interrupted by changing areas without rotation.
  • the two slivers provided with S and Z twists in the same way are finally brought together at the so-called unification point.
  • the slivers start to twist automatically, i.e. H. they wind around each other. This so-called folding maintains the S and Z twists in the individual slivers, so that a self-stabilizing two-component roving is created.
  • the areas without rotation in the first sliver should be offset in the longitudinal direction from the areas without rotation in the second sliver, so that there are never two areas without rotation of the first and second sliver lying side by side in the resulting roving, since the The strength of the roving essentially depends on the phase position of the areas without rotation of the two slivers.
  • the rovings are therefore, as described above, always brought together with the strengthening agent so that their areas are out of phase without rotation.
  • the roving produced in this way finally has a higher strength than a non-twisted fiber composite, which in the end is sufficient to wind the roving onto a spool without any distortion and to unwind it again.
  • WO2013143875 discloses a roving machine for producing a roving, it being proposed that the roving machine comprise an arrangement for detection and removal of yarn defects to be passed by the roving, the arrangement being placed between the outlet of the spinneret and the take-over device.
  • DE2443920 discloses an optical measuring device for an automatic multi-station yarn processing machine.
  • EP2455318A1 discloses an automatic winder management system.
  • the object of the present invention is therefore to propose a method for operating a textile machine and a corresponding textile machine which do not have this disadvantage.
  • the method is characterized in that when it is detected with the aid of the sensor system mentioned that no roving is produced from the strengthening agent or that the roving manufactured by the strengthening agent is not wound onto the sleeve, normal operation is interrupted.
  • the interruption can take place, for example, if the strengthening agent becomes blocked during the supply of the fiber bandage, so that roving production can no longer take place.
  • the roving can tear between the setting agent and the winding device, so that the roving subsequently produced by the setting agent no longer reaches the area of the winding device or a traversing device assigned to it (which moves the roving in a reciprocating manner during the winding process Movement along the axis of rotation of the sleeve leads).
  • the air supply to the solidifying agent is preferably interrupted.
  • the winding device is stopped, or a drive that rotates the sleeve during normal operation.
  • a possibly existing take-off device e.g. a pair of take-off rollers arranged downstream of the solidifying agent
  • a possibly existing traversing device should be shut down.
  • a starting process is carried out in which roving produced by the setting agent after the start-up thereof comes into contact with the empty (new) tube brought.
  • one or more roving handling devices of an arrangement can be used, which grasp the roving coming from the setting agent and move it into the area of the winding device or said traversing device.
  • the roving produced by the strengthening agent is wound onto the sleeve and normal operation is resumed.
  • a sleeve located in the winding device is only rinsed with roving until it has a predetermined degree of rinsing or until there is an unwanted interruption of the roving production by the solidifying agent or until for some reason the winding of the the roving supplied with the setting agent fails on the sleeve.
  • the stated strengthening agent can be designed differently.
  • the strengthening agent is suitable, the roving on the in the above-mentioned documents WO 2009/086646 A1 and DE 24 47 715 A1 to produce the manner described.
  • the textile machine is preferably designed as an air spinning machine and the consolidation means as an air spinning nozzle, through which the protective rotation of the roving, as described above, is generated with the aid of eddy air currents (a section of a corresponding textile machine designed as an air spinning machine is described by way of example in the description of the figures).
  • a drafting device which is arranged upstream of the consolidation means in the transport direction mentioned, is stopped for stretching the fiber structure.
  • the setting agent can be freed of impurities or blockages in order to be able to reliably produce roving again during the starting process.
  • the solidifying agent is designed as an air spinning nozzle, it is advantageous if, as part of the interruption, the supply of the air introduced into the spinning nozzle during normal operation to generate the swirling air flow is stopped in order to enable cleaning of the spinning nozzle.
  • the drafting system is finally put into operation again and the setting agent or the air supply to the air spinning nozzle forming the setting agent is activated in order to enable the necessary roving production in this process step.
  • any take-off device or the traversing device mentioned is put back into operation in order to ensure that the roving is guided between the setting agent and the winding device or sleeve.
  • the roving produced by the setting agent during normal operation is monitored between the setting agent and the currently spooled sleeve with regard to one or more physical parameters.
  • the parameters can be the current thickness of the roving or averaged over a certain period of time (or otherwise statistically evaluated) or deviations from it from a target value (range).
  • target value range
  • roving production can also take place automatically in the event of unwanted interruptions, the corresponding sleeves being replaced by an empty sleeve whenever there is an interruption in the roving strand arriving at the winding device. It is advantageous if cores that were completely spooled during normal operation in accordance with a predetermined setpoint value and cores that were only partially spooled with roving due to an interruption of normal operation are transported to separate collection or transfer points after the respective core change processes. This can be done either by arranging the separate collection or transfer points directly in the area of the winding device, and by the tube changing device, depending on the degree of spooling (ie whether the tube is completely or only partially spooled with roving) in accordance with the relevant specifications passes both places.
  • the sleeve changing device transfers the corresponding sleeve to one of the transport devices depending on its degree of spooling.
  • a first transport device only receives the fully wound sleeves and a second transport device only accepts the sleeves that are only partially wound due to an interruption of normal operation and transports them to corresponding removal or storage locations.
  • the sleeve changing device only one Transport device is assigned, which in turn has one or more switches, with the aid of which the sleeves can be guided to subsequent transport devices or removal or storage locations, depending on the degree of spooling.
  • the solidifying agent is cleaned after an interruption of normal operation and before normal operation is subsequently resumed, in order to remove fibers of the fiber assembly and / or roving still present in the solidifying agent from the solidifying agent.
  • the cleaning can take place, for example, by (preferably automatic) introduction of compressed air or also manually. It is also possible to clean the drafting system, the draw-off device or the traversing device mentioned, if there were blockages or other undesirable deposits of fibers of the fiber composite or roving before the normal operation was interrupted.
  • the sleeve changing process, the starting process and the resumption of normal operation take place within a maximum of 120 seconds, preferably within a maximum of 60 seconds, particularly preferably within a maximum of 40 seconds, after the previous interruption of normal operation. This prevents an excessive interruption of normal operation, resulting in high productivity of the textile machine.
  • the process sections mentioned can be carried out sequentially or overlapping in time.
  • the textile machine according to the invention (which can include one or more of the above-mentioned work stations) is characterized by the fact that it is assigned a controller which is designed to interrupt normal operation when it receives the signal from the sensor system that the solidifying agent no roving is produced or that the roving produced by the strengthening agent is not wound onto the sleeve.

  • the tearing of the roving 2 finally creates a section of the roving 2 on the suction unit side which can be removed via the suction unit 24.
  • a roving section on the side of the air spinneret is also created, which is already gripped by the sleeve 6 and which extends between the air spinneret 3 and the sleeve 6.
  • the roving 2 still supplied by the air spinning nozzle 3 is finally continuously wound onto the sleeve 6, the traversing element 8 ensuring that the roving 2 is uniform by moving in a direction running parallel to the axis of rotation 11 of the sleeve 6 is wound on the sleeve 6.
  • the air spinning machine 1 is finally in its normal operation following the starting process, in which the sleeve 6 is rinsed with roving 2 until the desired bobbin size is reached is and the spooled sleeve 6 can be replaced by a new, empty sleeve 6, which can be done without interrupting the roving.
  • the roving 2 between the air spinneret 3 and the winding device 5 breaks or that the drafting device 13 and / or the air spinneret 3 clog with fibers, so that roving 2 is no longer produced in the air spinneret 3.
  • the result is that roving 2 no longer reaches the area of the winding device 5, this being done with the Figure 1 indicated sensor system 9 can be recognized (for this purpose the sensor system 9 comprises one or more sensors which can be placed in the area of the drafting device 13, the air spinning nozzle 3, the traversing unit 21, the winding device 5 or also between the elements mentioned).
  • the starting process described above is carried out, in which roving 2 produced by the air spinning nozzle 3 after a corresponding start-up (during which the air spinning nozzle 3 is again supplied with a fiber structure 4) with a roving 5 that is now in the winding device 5 empty sleeve 6 is brought into contact. Finally, the roving 2 produced or supplied by the air spinning nozzle 3 after the starting process is wound onto said sleeve 6 and normal operation is resumed.
  • the roving 2 produced after the interruption is therefore not connected to the roving 2 previously produced and wound onto the corresponding sleeve 6. Rather, with each unwanted interruption of the roving or the winding process, normal operation is interrupted, during which the partially spooled sleeve 6 is replaced by an empty sleeve 6.
  • the interruption of normal operation and the subsequent sleeve changing process and the corresponding starting process also take place when the sensor 9 mentioned detects that certain physical parameters, for example the thickness of the roving 2 leaving the air spinning nozzle 3, do not correspond to the desired specifications.
  • the sleeves 6, which are only partially spooled due to an interruption of normal operation are preferably transported to a different location than the sleeves 6, which have been completely wound without interrupting normal operation, preferably with the aid of the sleeve transport device 28.
