Definitions

  • the invention relates to a thread feed gun, consisting of a connecting piece and a diffuser with a mouthpiece and a method for cooling the mouthpiece thereof.
  • Mobile thread feed guns are used to handle melt-spun synthetic threads.
  • a thread feed gun of the type is known. With this, the thread is caught below the spinneret and then placed on the thread-guiding or guiding machine parts such as reels, reel duos, deflection thread guides and finally thread spool.
  • Such suction guns usually work with a gaseous or liquid medium as a propellant and allow the manipulation of threads that run at speeds of up to 6000 m / min.
  • the known thread feed gun has several disadvantages.
  • the mouthpiece which is too short, is not suitable for safely removing and reinserting threads in the remaining rooms with high-speed machine parts in a tight arrangement and safely.
  • the object of the invention is to minimize the thread friction-related heating of the mouthpieces of thread pulling guns and to provide a mechanically reliable device that is safe for the operating personnel.
  • the extension tube has the advantage that manipulation between tightly arranged machine parts is possible.
  • the jacket is preferably made of a plastic and thus has a protective effect on the preferably metal extension tube on the one hand and on high-speed machine parts (rollers etc.) on the other.
  • the annular space between the extension tube and the jacket serves as a flow channel for a cooling medium.
  • the outlet openings are provided in such a way that the direction of the emerging cooling medium has a component in the direction of the housing, as a result of which a disruption of the thread path in front of the mouthpiece is avoided.
  • the angle of the inclination of the bores measured from the axis of the extension tube 3 should be> 90 degrees, so that the flow points backwards away from the mouthpiece. This has the advantage that the cooling air cannot disrupt the thread feed in the area of the feed eyelet.
  • the mouthpiece of the thread feed gun consists of an eyelet holder and an inlet eyelet, but it can also be made from a single part.
  • Ceramic has preferably proven to be suitable as the material for the inlet eyelet. Material coated with ceramic, such as metal, is also suitable.
  • the inlet eyelet can also consist of a good heat-conducting material.
  • materials coated with a hard metal such as chrome are also suitable.
  • the extension tube is provided with cooling fins in the area of the mouthpiece.
  • a thread take-up tube of the feed gun is designated as diffuser 1.
  • a nozzle ring 2 is provided, which is connected to an extension tube 3.
  • the diffuser 1 and the extension tube 3 are surrounded by a housing 4 in the region of the nozzle ring 2.
  • a ring of, for example, 5 to 10 injector nozzles 5 is provided in the nozzle ring 2, which are adapted according to the propellant from gas or liquids.
  • the housing 4 and the nozzle ring 2 form a distribution chamber 6, which continues against a connecting piece 7.
  • the extension tube 3 carries at its free end a mowing piece 10, the inside of which shows an inlet eyelet 11.
  • the extension tube 3 and the mouthpiece 10 are surrounded by a jacket 12, which preferably consists of a plastic. Between ver Extension tube 3 and the jacket 12, an annular space 13 is formed. On the opposite side of the connecting piece 7, a connecting tube 8 is provided, which is connected to the annular space 13 on the extension tube 3 via a constriction 9.
  • the jacket 12 is interrupted in the area of the mouthpiece 10 by a ring of 8 to 20 bores 14, 14 ', the openings of which point away from the mouthpiece 10.
  • the cross section of the annular space 13 is large compared to the cross section of the diaphragm and the sum of the cross sections of the bores 14, 14 '.
  • the thread pulling gun is supplied with compressed air of, for example, 5 to 15 bar, in particular 12 to 14 bar, via the connecting piece 7.
  • compressed air of, for example, 5 to 15 bar, in particular 12 to 14 bar
  • the majority of the compressed air flows through the injector nozzles 5 in a known manner, as a result of which a negative pressure is generated in the extension tube 3 and in the mouthpiece 10, which is able to suck threads through the diffuser 1.
  • a partial flow of the compressed air is introduced via the constriction 9 through the connecting pipe 8 into the annular space 13 and is carried forward to the mouthpiece 10. There, this partial flow can emerge again through a row of bores 14, 14 'in the jacket 12, which holes surround the mouthpiece 10.
  • This partial flow is used to dissipate the frictional heat generated as a result of the thread friction on the mouthpiece 10, so that the inlet eyelet 11 is effectively cooled in the mouthpiece 10.
  • the effect of this measure manifests itself in the fact that even after repeated thread application, neither the ceramic parts shatter nor the thread material within the mouthpiece 10 melts.
  • the thread feed gun according to the invention enables the handling of Schnellau in a particularly advantageous manner use textile threads primarily for industrial use and for placing them on high-speed machine parts.
  • the use of the invention is suitable for melt-spun synthetic threads over 1100 dtex and final speeds of about 6000 m / min and more.
