Definitions

  • the invention relates to a thread suction device with a thread suction nozzle arranged substantially perpendicular to the thread path.
  • Such thread suction devices are mainly used in processes for processing continuous filaments, e.g. in draw-winder or spin-draw-wrap processes.
  • Suction devices generally work together with thread monitoring elements in order to interrupt the thread supply at these points as quickly as possible in the event of faults occurring in the thread run at subsequent processing points.
  • the object of the invention is therefore to remedy this disadvantage and to solve it with the features listed in the characterizing part of the first claim.
  • the invention can also be used with advantage for individual threads if vibrations in the thread cannot be avoided at the suction point.
  • a thread suction device comprises a head part 1 and a diffuser part 2.
  • the head part 1 is guided in a bore 3 of a machine frame 4 and bears against the machine frame 4 with an associated flange 5.
  • Two screws 6 fasten the head part 1 to the machine frame 4.
  • the diffuser part 2 is screwed into the machine frame 4 by means of thread 7.
  • an O-ring 8 seals the air passage transversely to the air flow direction S.
  • the head part 1 also includes a so-called one-sided pressurized, secured against rotation, pneumatic piston 9 with a flow channel 10 for guiding the air flow S.
  • a mouth part 12 made of ceramic material is firmly embedded in the piston 9. Furthermore, a hollow cylindrical extension 13 of the piston 9 forms the opening of the channel 10 opposite the diffuser part 2.
  • the head part 1 further includes a stationary cylinder part 14 with a cylinder cover 15 firmly connected to the cylinder part 14.
  • the aforementioned flange 5 is also a component of this cylinder part 14.
  • the piston 9 is slidably guided in the cylinder part 14 and in the cylinder cover 15.
  • the compressed air required for moving the piston 9 is guided through an inlet opening 16 provided in the intermediate part 14.
  • the compressed air acts primarily on an annular surface 17 provided on the piston 9, and after lifting off the piston, the annular surface resulting from the difference in diameter D-d is then applied.
  • a coil spring 18, which is subjected to pressure, is used to return the piston 9 to the initial position of the piston 9 shown in FIG. 1.
  • the compressed air is supplied from a compressed air source 19 via a two / two-way valve 20 or a three / two-way valve 21 (the variants will be explained later) and via a connecting part 22 through channels 23 and 24 in a distribution chamber 25 and then into the inlet openings 16 out.
  • the air flow S required for the suction of the threads 11 can either be generated by a vacuum source, not shown, used after the diffuser part 2, or by drilling holes, not shown, in the diffuser, which are connected to the distribution space 25 in such a way that the Inflow of the compressed air through the channels (not shown) into the diffuser part creates a negative pressure in the channel 10.
  • the valve 20 is used, since the ventilation necessary for the backward movement of the piston can take place through the channels, not shown.
  • Venturi nozzles can also be used as diffuser parts and the channel 10 can be adapted to these nozzles.
  • valve 20 for the passage of air from P to A is brought into the corresponding position for the suction of the threads 11 so that on the one hand the piston 9 performs a stroke until an O-ring 26 strikes the cover 15 and the mouth part 12 pushes the threads 11 together into a single thread, and on the other hand the air flow S is generated in the manner mentioned.
  • a cutting device (not shown) connected downstream in the thread running direction F has cut the threads 11, these are sucked off together and practically with the same intensity.
  • the mentioned vacuum source is activated simultaneously with the displacement of the valve 21 for the passage of the compressed air from P to A.
  • a hollow cylindrical extension 28, which is part of the piston 9 and is provided with slots 27, is used to direct the air flow before it enters the mouth part 12.
  • seals 29, 30 and 31 are provided to prevent leakage air from escaping.
  • the diffuser part is connected directly to a receptacle (not shown) by means of a hose 32 or via a vacuum source.
  • a head part 100 is guided in the bore 3 and is located on the machine frame 4 by means of an associated flange 101 and is fastened to it by two screws 102.
  • the head part 100 also comprises a stationary cylinder part 103 with a cylinder cover 104 attached to it, and a pneumatic piston 105 secured against rotation, which is displaceably guided on a coaxial mandrel 106 belonging to the cylinder part 103.
  • the piston 105 can be acted upon on an annular surface 107 with compressed air for displacement against the force of a spring 108.
  • the piston stroke is limited by the stops 109 and 110.
  • corresponding O-ring seals 111 and 112 can be provided.
  • Recesses 114 for the threads 11 are provided on an outwardly projecting, likewise hollow cylindrical extension 113 of the pneumatic piston 105.
  • a channel 115 with an opening 116 for the passage of the air flow 5 is likewise provided in the mandrel 106.
  • the piston 105 is supplied with compressed air as shown in FIG. 3 through the channels 23, 117 and 118.
  • the valve 20 or 21 is now used, as mentioned earlier, depending on the variant for generating the air flow S.
  • the surface 107 is supplied with compressed air via the channels 23, 117 and 118 and the piston 105 is pushed against the force of the spring 108 until the stroke 110 is limited by the stop 110.
  • This movement inevitably also shifts the extension 113 and thus a driver 119 provided on the extension.
  • the threads 11 are pushed together until all the threads abut the mouth 116, after a thread cutting device (not shown) that is switched off in the thread running direction Cut threads to be sucked together and with practically the same intensity for all threads.
  • the air in the room in which the spring 18 or 108 is located escapes through an opening (not shown) into the atmosphere during the piston stroke.
