Definitions

  • the invention relates to a suction nozzle for a workstation of a cross-wound textile machine according to the preamble of claim 1.
  • the Spulstellenrechner ensures that, such as in the DE 40 05 752 A1 described, first applied a so-called suction nozzle with its mouth to the surface of the slowly rotating against the winding direction of the package winding and subjected to negative pressure.
  • the suction nozzle attempts to record with its mouth the yarn end of the upper thread from the surface of the package designed as a cross-wound bobbin.
  • the suction nozzle pivots back to its original position, in which the mouth of the suction nozzle is positioned below a yarn ply device.
  • the yarn strand extending between the cross-wound bobbin and the suction nozzle is placed in an electronic cleaner arranged above the yarn joining device, a clamping and cutting device positioned in this region and, by means of corresponding guide contours of Thread guide plates and Fadenleitbügeln out, fed into the shears of a cutting device located below the splicer.
  • a gripper tube positioned in a lower starting position pivots into an upper working position, bringing with it a lower thread that has been held until then, for example in a thread tensioner, drawn from the supply spool.
  • the present invention seeks to develop a suction nozzle, which is designed so that an accumulated on the cross-wound yarn end of an upper thread can be handled safely.
  • the suction nozzle according to the invention has the advantage that the effective suction air flow within the suction nozzle, especially in the region of the inlet opening, concentrated concentrated on the lateral edge regions of the inlet opening of the suction nozzle and thus becomes more effective in the problem areas of the package.
  • this section of the suction nozzle is divided into two lateral cross-sectional areas and an intermediate cross-sectional area arranged therebetween, the air flow in the region of the lateral cross-sectional areas, not least because of their far greater height, above the air flow rate of the central cross-sectional area ,
  • the profiling is preferably part of a Saugdüsendeckels, which is connected, for example via bolts, with a Saugdüsenfuß.
  • Such an embodiment can be realized inexpensively by injection or pressure casting.
  • the suction nozzle in its end region on air guide surfaces, which are advantageously integrally formed on the Saugdüsendeckel.
  • the comb strip for example, when pivoting back the suction nozzle ensures that, for example, loops, which may be present in the recorded thread, are combed out, so that there is always only a single thread during the subsequent yarn joining process.
  • Fig. 1 is a side view schematically a job 2 of a cheese-producing textile machine, in the embodiment, a so-called cross-winding machine 1, shown.
  • the spinning rings 3 produced on ring spinning machines are rewound to large-volume cheeses 5 on the workstations 2 of such automatic winder 1.
  • the cheeses 5 are after their completion by means of a (not shown) automatically operating service unit, preferably a cheese changer, handed over to a machine-length cheese package transport means 7 and transported to a machine end side Spulenverladestation or the like.
  • a (not shown) automatically operating service unit preferably a cheese changer
  • such automatic packages 1 also have a logistics device in the form of a package and tube transport system 6.
  • the spinning cops 3 or empty tubes run on transport plates 11. From the sleeve transport system 6 are in the Fig. 1 only the Kopszu slaughterhouse 24, the reversibly driven storage section 25, one of the leading to the winding units 2 transverse transport sections 26 and the sleeve return path 27 shown.
  • Each workstation 2 of the automatic winder 1 has a workstation computer 28, which is connected via a bus connection 29 to a central control unit 30 of the cheese-winder 1, as well as various other devices which are necessary for the proper operation of the workstations 2.
  • Such a winding device 4 has a coil frame 8 which is movably mounted about a pivot axis 12.
  • Fig. 1 indicated in the creel 8 freely rotatably supported cross-wound bobbin 5 during the winding operation with its surface on a support and drive roller 9, which is acted upon by an electric motor 33.
  • the electric motor 33 is connected via a control line 35 to the workstation computer 28.
  • Fadenchangier listening 10 For traversing the thread 16 during the winding process a Fadenchangier listening 10 is provided.
  • Fadenchangier aggr 10 consists for example of a finger thread guide 13, which, acted upon by an electric motor drive 14, traversing the accumulating on the cheese 5 thread 16 between the end faces of the cheese 5 traversed.
  • the thread guide drive 14 Via a control line 15, the thread guide drive 14 is in operative connection with the workstation computer 28.
  • Such jobs 2 also have a thread connecting device 42, preferably a pneumatic splicing device, a gripper tube 43 for handling the lower thread and a suction nozzle 17 according to the invention, with which the accumulated on the cheese 5 and the upper thread can be inserted into the thread connecting device 42.
  • a thread connecting device 42 preferably a pneumatic splicing device, a gripper tube 43 for handling the lower thread and a suction nozzle 17 according to the invention, with which the accumulated on the cheese 5 and the upper thread can be inserted into the thread connecting device 42.
  • the suction nozzle 17 in this case has a flow-optimized suction nozzle head 18 whose specific shape is described below with reference to FIG Figures 2-4 is explained.
  • the Fig. 2 shows a perspective view of the suction nozzle head 18 according to the invention, which consists essentially of a suction nozzle 39 and a Saugdüsdeckel 37, which are connected by bolts 38 or the like.
  • the Saugdüsenfuß 39 has in its end region on a connecting piece 36 which is fixed in a pivot tube of the suction nozzle 17.
  • the suction nozzle cover 37 has an inwardly directed profiling 34, which protrudes into the clear cross section of the suction nozzle 17 in such a way that lateral cross-sectional areas 21 and a central cross-sectional area 22 are formed in the region of the section 20 of the suction nozzle 17.
  • air guide surfaces 40 are formed on the Saugdüsendeckel, which provide a defined air flow.
  • the lateral cross-sectional areas 21 in the majority of the portion 20 to a height H which is in each case significantly above the height h of the adjacent central cross-sectional area 22.
  • an inlet region 19 with an inlet opening 23 is arranged.
  • the inlet opening 23 is thereby enclosed by a comb strip 41 which meshes with the swiveling back of the suction nozzle 17 any loops from the recorded thread 16.
