    专利说明:

    The invention relates to a textile machinery industry, namely, to a device for cleaning a zone for laying a weaving loom into the shed of a weaving machine with at least one positioned air-jet nozzle stationary in the space at the top of this zone.
    The purpose of the invention is to increase the cleaning efficiency.
    Figure 1 schematically shows the area in the throat of the weft thread of a loom with a clamping shuttle, which is equipped with the proposed device; Fig. 2 shows a part of the device, the direction of laying the weft yarn; figure 3 is the same, side view; Fig. 4 is a variant of the design of an air outlet with one-sided deflection of the air jet, the cut perpendicular to the exit spline; Fig. 5 shows the laying area in the throat of the weft yarn (option) side view.
     . A device for cleaning the laying area of the weft yarn and includes attached to the power supply air. (not shown) the slit injection nozzle 1, which is pointed across the direction of the weft thread, and the inclined discharge nozzle 3 directed obliquely relative to the laying zone 2, located in front of the nozzle 1 in the direction of the weft thread. Both nozzles 1 and 3 sit at the end of the common distribution pipe 4;
    The slit nozzle 1 is positioned and directed so that it forms a vertical air curtain between the thread catcher 5 and the weft threading zone 2.
    The area of the plot is partially represented: the front and rear locking bar 6 or 7, respectively, and the separating separator ridge 8 with its own driving lever 9, are shown in the foreground, with the weft yoo Yu, shown by the dash-dotted line, the diverting lever 11, retraction or nitrite givatel 12, clamping hook 13, as well as guides 14 for the combat mechanism 15 (figure 5).
    The air flow from the discharge nozzle 3 located at InoHHo 3 is directed primarily to the guides 14 of the shuttle 13 and to

    the thread transfer, while the air outlet hole 16 of the additional slotted nozzle 1b, with its periodically deflected air jet, closes the thread tension regulator 17, brake 18 and weft spool 19.
    The principle of operation of the air outlet 16 of the nozzle 1b and its design are as follows.
    Against the fabric 20 or, correspondingly, of the shed 21 (Fig. 1), the air curtain formed by the action of the slotted nozzle 1 is bounded by a shielding plate 22, which has an open groove below, below the shielding plate 22 are presented on the lock batten bar 6 controlling the thread catcher 5, and in front of it a centering flyer 24. As shown by the arrows (FIG. 1), some of the air from the slit nozzle 1 flows vertically downwards, while the other part blows the air method 25 for lubrication of the invader, which is spatially located in front of the front lock batten bar 6 and in front of the shaped plate 23. Purging the device 25 for lubricating the shuttle can be further improved if the shield plate 22 (Fig. 3) is complemented parallel to the the direction of the laying of the weft thread 10 side-septum 26.
    When processing, for example, yarns that are only slightly prone to fluff formation or from which only relatively short fibrous fluff leaves, it is also possible to use shielding plate 22 (Fig. 2), which is closed along. downwardly so that it practically forms a passage wall in which there is only a passage opening 27 for the shuttle 13. By using the shielding plate 22 closed or, respectively, elongated downward, the screening between the air curtain and the shed 21 for the above mentioned thread types is improved.
    The air outlet 16 (Fig. 4) is located in the housing, which is locked at its one end by means of a non-visible front
    walls, while the non-shown back wall communicates with the pressure distribution pipe 15. The nozzle 1b has a tangential tapering in the form of a funnel, the output slot 28, which is formed by the side wall 29 of the housing and the profiled body 30.
    In the direction of air flow after the exit slot 28 below the profiled body 30, an element 31 is provided, which consists of two cylindrical segments that are displaced one relative to the other along the axis of symmetry and can rotate around its axis 32, for example, an electric motor (not shown). It is also possible to unite the element 31 with a self-drive, in this case, for example, a part of it along the length is made in the form of a gear wheel of an air turbine. This self-drive could lead to an increased number of revolutions for the element 31, since it should be maximally equal to 30 rpm with a two-stage design. In this case, the self-drive is braked by means of a friction brake. Since during operation, for example, by

    If the impurities in the air drive blower and / or in the support of the element 3 change the braking force required to maintain a certain number of revolutions, the friction brake braking force is adjusted.
    Axis 32 relative to the output slot 28 moves sideways so that the surfaces of the element 31, which are composed of two separate along the axis of symmetry 33 and the halves of the cylinder cylinder body that are displaced relative to each other, enter the air flow protruding from the output slot 28 one-way in the direction of the element; that 31.
    The steps 34 of the element 31, which arise by displacing the cylindrical halves, help the flow adjacent to the curved surface to break off; after a half-turn, the elemental 31, thereby eliminating the deviation of the air v of the jet and the air flow rebounds in the direction of the exit spline 28. If uniform and does not occur

    The device (Fig. 5) is supplemented with other areas of the purge, through the use of which improvements can be achieved in maintaining the cleanliness of the machine and, as a final step, regarding the quality of the fabric produced with an increase in investment costs.
    The air supply source (when lowering unnecessary pipelines and components) may be used.
    All blower areas on the loom are provided from fan 36 at high pressure 5 through pipelines 37 and 38, while pipe 37, which provides air to the blowing sections above the machine, for a number of branch pipelines. 37 a - 37 d. One of the answers to piping 37 a - 37 d turns into (fig.) Pressure pipe 4, which supplies air to the nozzles 1 and 3. Pipe 38 leads to the cleaning ring nozzle 39 located behind the thread tension regulator 17.

    The branch pipes 37 b and 37 s are equipped with pulsators 41 carried out by the engine, through which the pressure nozzles connected to them — slot nozzles 1 and 3 and inclined nozzle 42 — can be provided intermittently
