Definitions

  • the invention relates to a device for cleaning the weft-insertion-region of a loom with at least - least one fixed position in the room air delivery nozzle disposed above this range.
  • the object of the invention is therefore to provide a simple and robust device for cleaning the weft insertion area, with which improved cleaning effects are achieved.
  • This object is achieved by a combination of individual measures, the interaction of which results in the improved effectiveness of the overall device.
  • the combination is characterized in that a slot nozzle running transversely to the weft thread direction places a vertical air curtain between the thread scissors and the weft area, and that on the thread run side of the thread scissors a cover plate limits the air curtain on the weaving side.
  • the parts of the weft insertion moving towards the sley promote the tendency in the flying material - both when it is created and when it is whirled up by air jets blowing downwards, which also hit parts of the weft mechanism and are deflected there move a component in the direction of the weft path; on the other hand, the air curtain acts as a "lock".
  • the cover plate which - depending on whether the yarn to be processed tends to be more or less prone to flight - can be open, closed or extended at the bottom, it protects the sley and thus the fabric against the flight generated in the weft mechanism ; Fiber parts (fluff) coming into the curtain are guided downwards out of the machine.
  • one of the Direction of weft thread at an obliquely directed air blow-out nozzle to the weft area and / or an air outlet designed as a slot running transversely to the thread running direction to the area of the thread tensioner and thread brake.
  • the air outlet also has the effect that flight blown from the air blowing nozzle into its area of action is removed from the machine. Its effectiveness can be improved if, in addition to the air outlet on the thread inlet side, a rotating round body periodically deflects the air jet emerging from the air outlet on one side against the weft thread run; the round body is, for example, a step body with at least one step; However, it can particularly advantageously consist of circular cylinder sectors with the same radii that are displaced with respect to one another along a diameter, expediently having two to four steps on the circumference of the step body.
  • the round body can be driven either by a motor or by the air to be deflected itself, limiting the number of deflections per min. - 1 - 60, preferably up to 30, deflections / min are advantageous. - The speed of the round body can be limited by an adjustable friction brake.
  • the periodically deflected air jet with the help of the round body "sweeps" the flying material (fluff) in the direction of the bobbin frame, before which it can easily fall under the machine.
  • the cover plate can not only be open or closed at the bottom, but can also have a diaphragm-like end extending laterally to the thread inlet side. With such a closure, the jets that form the air curtain are guided over a longer distance and thereby improve the blowing off of the projectile lubrication point.
  • the division of the cleaning device into a number of individual elements blowing in different directions ensures that there are no "dead” corners in the firing mechanism, in which the flight can be deposited again after it has been captured and transported by the blown air.
  • the device can be improved if there is an additional double jet nozzle on the cover side of the shutter which is inclined towards the vertical above and below the weft thread Air jets directed transversely to the thread direction on the centering wing. Further improvements in cleaning in the area of the firing mechanism in the narrower sense, i.e.
  • Discontinuously generated air jets from part of the blow-out elements also promote the cleaning action due to the impact effect of new air jets, whereby pulse frequencies of 1-50 per min., Preferably below 30 / min., Are maintained.
  • the speeds or energies of the “cleaning” air jets are to be selected in the new device in such a way that flying material is transported away as extensively as possible, but the guidance and position of the thread is not impaired by the blown air.
  • FIG. 1 shows a view of the weft insertion; of a weaving machine in the direction opposite to the weft, i.e. seen from the machine.
  • An air supply not shown, for which an exemplary embodiment is shown in connection with FIG. 5, is connected to a slot nozzle 1 which is transverse to the weft direction and an air blowing nozzle 3 directed obliquely against the weft mechanism 2. Both nozzles 1 and 3 sit at the end of a common distribution line 4.
  • the slot nozzle 1 is arranged and directed so that it places a vertical air curtain between the thread scissors 5 and the weft mechanism 2.
  • the weft mechanism is only shown schematically and partially: For example, in the foreground the front and rear lock blocks 6 and 7 and the retractor 8 with its drive lever 9 are sketched, while behind the dash-dotted weft thread 10 the retractor lever 11, the retractor or thread take-up 12, a projectile 13, as well as guides 14 for striking mechanism 50 (FIG. 5), retractor 12 and projectile 13 are recognizable.
  • the air flow emerging from the inclined air outlet nozzle 3 is directed primarily at the guides 14 of the projectile 13 and the thread transfer, while the air outlet 17 sweeps with its periodically deflected air jet thread tensioner 16, thread brake 18 and weft bobbin 15.
  • the air curtain formed by the slot nozzle 1 is limited by a cover plate 19 which is open at the bottom; Under the cover plate 19, the cam plate 20 for controlling the thread scissors 5 and in front of this the centering wing 21 are shown.
  • a cover plate 19 which is open at the bottom; Under the cover plate 19, the cam plate 20 for controlling the thread scissors 5 and in front of this the centering wing 21 are shown.
  • part of the air flows out of the slot nozzle 1 vertically downwards, while another part is blown onto the projectile lubrication 22.
  • the blowing off of the projectile lubrication 22 can be further improved if the cover plate 19, as shown in FIG. 3, is supplemented by a side wing 23 which extends parallel to the weft thread 10 but against the thread course.
  • cover plate 19 ' (FIG. 2) which is closed at the bottom, so that it practically forms a continuous wall in which only the passage opening 26 for the projectile 13 is present.
  • the shielding between the air curtain and the shed 25 for the types of yarn mentioned is improved with a cover plate 19 'which is closed or extended downwards.
  • the air outlet 17 (Fig. 4) has a housing which is closed at one end by a front wall, not shown, while in the also not shown Rear wall opens a compressed air distribution line; a pressure chamber 30 is thereby formed in the air outlet 17.
  • This has a tangential, narrowing funnel-shaped exit slot 31, which is formed by a side wall 32 of the housing and a molded body 33.
  • a round body 34 which can rotate about its axis 35, is provided after the outlet slot 31 below the shaped body 33, an electric motor (not shown) being used for its drive;
  • the round body 34 it is also possible to design the round body 34 to be self-propelling, for example by forming part of its axial length as a gear-type air turbine.
  • This self-propulsion would, however, leave itself too high speeds for the round body 34, since, as already mentioned, with a two-stage design, these have a maximum of 30 rpm. may be; in this case the self-propulsion is braked by a friction brake. Since the braking force required to maintain a certain speed changes during the course of operation - for example due to contamination in the fan of the "air drive" and / or in the mounting of the round body 34 - the braking force of the friction brake can be adjusted.
  • the axis 35 is laterally offset against the outlet slot 31 such that the curved surfaces of the round body 34, which in the example shown consist of two halves of a circular cylinder jacket separated and displaced along a diameter 36, protrude into and out of the air stream emerging from the outlet slot 31 deflect on one side towards the round body 34.
  • the steps 37 of the round body 34 produced by the displacement of the cylinder halves cause the flow against the curved surface to stop after half a turn of the round body 34, as a result of which the deflection of the air jet is canceled and the air flow "springs back" in the direction of the outlet slot 31. . If there is a uniform and continuous rotation of the round body 34, which is partially encompassed on one side by a wall 38 of the housing opposite the wall 32, a periodically one-sided air jet is generated in this way, which acts as an "air broom" thread tensioner 16 and thread brake 18 according to a "Turns away".
  • the device according to FIG. 5 is supplemented compared to that according to FIG. 1 by further blowing points, by means of which improvements in keeping the machine clean and thus ultimately in the quality of the fabric produced can be achieved, albeit with an increase in capital expenditure.
  • blowing points on a weaving machine are supplied with increased pressure via lines 41 and 42 by a fan 40, the line 41, which supplies the blowing points located above the machine, branching in a number of branch lines 41 a - d; one of the branch lines 41 a - d goes into that mentioned in FIG. 1 Compressed air line 4, which supplies the nozzles 1 and 3 with air.
  • the line 42 leads to a cleaning nozzle 43 which will be described in more detail later.
  • adjustable throttle bodies 44 e.g. Orifices are provided with which the pressure and thus the amount of blown air in each of these lines can be adjusted relative to the others.
  • the branch lines 41 b and c are equipped with motor-driven valves 45, through which the nozzles connected to them - slot nozzle 1, air blow nozzle 3 and an inclined nozzle 46 - can be supplied with discontinuously intermittently blown out air flows.
  • the blowing and cleaning effect is improved by the impact of individual air jet impulses. For example, pulse frequencies of less than 60 per minute, preferably below 30 / min, are maintained.
  • the fan 40 can either suck in air from the weaving room via a filter (not shown) or can be connected to a suction nozzle 48 under the weft mechanism 2, which extends over a wide area of the weft insertion, via a suction line 47, so that there is a large extent for the entire device closed air circuit results.
  • the branch line 41 d ends in a - symbolically indicated by a split - two-jet nozzle 49, which is directed towards the centering wing 21, but its two jets do not capture the weft thread 10 itself, but rather sweep past it, for example, in an essentially fork-shaped manner so as not to disturb its centering.
  • the inclined nozzle 46 the air jet of which runs essentially in the same direction as that of the air outlet nozzle 3, is arranged between the air outlet nozzle 3 and in the air outlet 17; it mainly blows on the percussion mechanism 50 and the thread transfer, which is indicated in FIG. 5 by the retractor 12.
  • the cleaning nozzle 43 is provided in the thread running direction immediately after the thread tensioner 16; this is, for example, a ring nozzle known per se (CH-PS 624.438) which surrounds the weft thread 10 and with which the thread 10 running out of the thread tensioner 16 is as far as possible freed of fibers adhering to it before it reaches the thread transfer.
  • the cleaning nozzle 43 is therefore a very effective addition to the "air broom" formed by the air outlet 17.
