Definitions

  • the present invention relates to a method for operating an air spinning machine, wherein the air spinning machine has at least one spinning station with a spinneret for producing a yarn, wherein the spinneret during normal operation of the spinning station, a fiber strand is fed via an inlet and in a predetermined transport direction, wherein the fiber strand Within a vortex chamber of the spinneret with the aid of a vortex air flow receives a rotation, so that from the fiber strand a yarn is formed, which finally leaves the spinneret via an outlet and is wound by means of a winding device on a sleeve, wherein after an interruption of the yarn production, a piecing process is carried out, in which a coil-side yarn end moves opposite to the transport direction through the spinneret, superimposed after passing through the spinneret with one end of the fiber strand and together with this via the inlet into the spinneret is brought, and after completion of said steps of the piecing process, the production of the yarn is continued by recording the
  • an air-spinning machine which has at least one spinning station with a spinneret for producing a yarn from a fiber strand fed to the spinneret, wherein the spinneret has an inlet for the fiber structure, an internal swirl chamber, a yarn forming element projecting into the swirl chamber and an outlet for the Having yarn produced in the interior of the vortex chamber by means of a vortex air flow.
  • Generic air-jet spinning machines are used to produce a yarn (as it is for example in the EP 1 718 791 A1 described) from an elongated fiber structure by means of a vortex air flow generated by corresponding air nozzles within the vortex chamber.
  • the outer fibers of the fiber structure are wound around the inner fibers (core) in the region of the inlet mouth of the generally spindle-shaped yarn formation element, so that a stable yarn is produced as a result, which is finally removed from the vortex chamber via the extraction channel and onto a sleeve with the aid of the aforementioned winding device can be wound up.
  • the yarn end and with it the end of the fiber strand is moved by switching on the air nozzles and by starting the winding device into the interior of the vortex chamber and exposed there to the vortex air flow (which at this time already the fiber strand supplying device, preferably through one of the spinneret in Transport Direction upstream drafting is formed, was taken into operation or to promote the fiber structure in the direction of the inlet of the spinneret).
  • the connecting or overlapping area between the yarn end and the end of the fiber strand finally passes the inlet mouth of the spindle.
  • the spinning process is now continued as usual, ie the spinning unit is operated again in normal operation and produces a yarn.
  • a corresponding piecing process is for example in the JP H11 43829 A described.
  • the object of the present invention is therefore to improve the piecing process compared with the prior art and to propose an air spinning machine for carrying out such a piecing process.
  • the method is characterized in that during the piecing process at least temporarily additive is applied to the end of the fiber composite (which is overlapped with the yarn end or has already been brought into contact with this) is applied (the addition of additive to a ring spinning machine is otherwise in of the CN 102 226 303 A described; the additive addition in the context of texturing a yarn is the US 3 478 398 A refer to).
  • the end of the fiber composite which is overlapped during the piecing process with said yarn end and is jointly introduced or sucked into the spinneret, wetted with an additive.
  • the additive can be water or an aqueous solution which may contain one or more additional substances.
  • the addition of the additive during the piecing operation stabilizes the overlapping area between the yarn end and the end of the fiber strand so as to provide a particularly stable bond area between the yarn ends Sections is created. A loosening of the connection area during the piecing process or the subsequent normal operation or the subsequent further processing of the yarn is thereby almost impossible.
  • connection region is positively influenced by the application of the additive, so that the connection region in the finished yarn is virtually no longer recognizable.
  • the additive may be sprayed onto the end of the fiber composite.
  • the additive storage may be designed depending on the choice of additive and may be formed for example by a tank, a distribution system or the spinning station associated supply cartridges.
  • one or more additive supply lines are provided, via which the additive reservoir is in contact with an additive delivery, the latter being able to be formed for example by a hollow needle, a spray head or an additive outlet opening of a channel section.
  • the application of the additive should take place at a stage of the piecing process in which the end of the fiber dressing is already moved in the direction of the spinneret in order to evenly add additive to the fiber structure.
  • the additive brings advantages when the additive is applied to the end of the fiber strand after being overlaid with the yarn end.
  • the additive addition is started is, as soon as or shortly after the fiber strand, for example by means of said drafting, is supplied in the direction of the inlet of the spinneret.
  • the connection area between the yarn end and the end of the fiber composite is thereby strengthened before it reaches the area of the vortex air flow within the vortex chamber.
  • the additive is applied in the region of the inlet or, viewed in the transport direction, before the inlet of the spinneret onto the end of the fiber composite.
  • the additive takes place in the region between the inlet of the spinneret and a device which delivers the fiber structure, for example a drafting device located upstream of the spinneret.
  • the additive-provided end of the fiber dressing does not come in contact with the fiber dressing delivery device, thus avoiding potential complications associated therewith.
  • the additive should therefore be applied in the immediate area before the inlet of the spinneret on the end of the fiber dressing.
  • the fiber guide element can have an additive outlet opening arranged in the interior thereof, which opens into a passageway through which the said connection region and the subsequently delivered fiber structure pass into the swirl chamber of the spinneret.
  • the volume flow of the added additive during the piecing process at least temporarily, an amount between 0.001 ml / min and 2.0 ml / min, preferably between 0.01 ml / min and 1.0 ml / min and / or when the mass flow of the supplied Additive during the piecing process at least temporarily an amount between 0.001 g / min and 2.0 g / min, preferably between 0.01 g / min and 1.0 g / min has. While a higher volume or mass flow could cause sticking of the portions of the spinning station in contact with the connection region, said region ensures a reliable connection of the yarn end and the end of the fiber assembly.
  • the volume or mass flow of the additive is regulated during additive addition by means of at least one valve, the valve being opened and closed during operation at least once per second, so that the additive supplied to the valve passes through the valve in a pulse-like manner ,
  • a valve is thus not continuously flowed through by additive.
  • the additive stream of a plurality of smallest droplets or additive units (if no liquid, but a gas or a solid is used) composed, which are generated by the rapid opening and closing and leave the valve.
  • volume or mass flow of the added additive during the piecing process is at least temporarily higher than during the normal operation of the spinning station following the piecing process.
  • the exact value can be selected depending on the properties of the fiber composite and / or its feed rate into the spinning station and / or the withdrawal speed of the yarn from the spinning station and can therefore vary depending on the application.
  • the volume or mass flow of the added additive during the piecing process is at least temporarily reduced compared to an initial amount, the reduction taking place in particular at the end of the piecing process. This makes it possible to gradually reduce the amount of added additive during the piecing process to the amount desired during the subsequent normal operation of the spinning station.
  • the reduction of the volume or mass flow of the added additive takes place continuously.
  • the reduction may be abrupt, gradual or even gradual (ie, uniform), with, for example, a linear decrease in the amount of additive delivered to the end of the fiber composite being conceivable.
  • the amount of added additive should, at the latest, be reduced to the amount intended for normal operation if the connecting region between the yarn end and the end of the fiber composite has passed the additive outlet opening of the additive supply, so that the following fiber structure is already provided with a smaller amount of additive the said connection area.
  • the air-jet spinning machine is characterized in that the at least one spinning station of the air-spinning machine (it can of course also be present several spinning stations) is associated with an additive supply, by means of which an additive can be applied to an present after an interruption of yarn production end of the fiber assembly.
