Definitions

  • the invention relates to a device for air conditioning the textile goods in a weaving machine with a feed channel for air conditioned in a central unit that runs under the machine in the longitudinal direction and that has at least one upward air outlet that extends in its longitudinal direction.
  • the distribution pipes and ducts or hoses of the second group of such devices require a high level of investment expenditure and are often undesirable or even impossible to accommodate due to space constraints.
  • the invention is therefore based on the idea of making such additional internals unnecessary for guiding the treated air and simply blowing the air into the room under the machine.
  • This requires a uniform distribution of the blown air over the length of the machine, i.e. on all air outlets within a weaving machine, and on the other hand, dust and fiber material that collect under the machine, especially in the area between the warp beam and the shafts, may pass through injected air cannot be whirled up and carried away due to an injection effect of the air jets.
  • the accumulation of dust and fiber material between the shafts and the goods tree is considerably less than the warp beam side of the shafts;
  • many weaving machines are equipped with dust collecting plates to protect the shaft drive against dust and fiber material, which deflect contaminants to the warp beam side.
  • the required uniform distribution over the entire length of the air outlet (s) is enforced by building a pressure chamber in the supply channel or the air outlet (s) by maintaining a relatively high pressure drop, for example of 50-200 Pa, in the cover of the air outlet receives.
  • the opening diameter of which can advantageously be less than 1 mm, for example less than 0.5 mm
  • the air is finally divided into individual jets which are so fine and "gentle" that they are not - possibly in the area of the cover Deposited fibers entrained by injection and swirled up again.
  • the necessary pressure drop depends on the speeds in the feed channel, which are about 2 - 12 m / sec. Air speed and pressure drop are assigned in the same direction, i.e. high speeds require a greater pressure drop.
  • the size and number of the outlet openings are in turn related to the necessary pressure drop, with a high pressure drop resulting in small opening dimensions and a relatively small number of openings.
  • An additional advantage of the arrangement of the air outlet from the shafts on the side of the fabric tree is that the air outlet is more accessible for cleaning or maintenance work, since the fabric tree is changed more frequently than the warp beam.
  • a particularly suitable cover for the air outlet consists of a textile fabric, for example a commercially available monofilament screen fabric made of polyamide, in which the side length of a mesh opening is less than 0.5 mm.
  • the distribution of the air in the space below the machine can be improved if the cover of the air outlet extends into the space with a convex curvature at least in the case of excess pressure in the supply duct.
  • the air outlet is directed into a storage space formed on the rear side of the dust collecting plate facing the floor, and that through openings are provided in the dust collecting plate for the air blown into the storage space;
  • the space under the machine can also be delimited from the goods tree by a flexible apron.
  • feed channels 2 are provided for the supply of conditioned air from a central station (not shown), one of which is shown in FIG. 1.
  • the feed channels 2 run in the longitudinal direction of the looms 3 and are common to the looms 3, which are arranged alongside one another in a row; therefore, the feed channels 2 and their air outlets 4 (FIG. 2) leading to the level surface of the floor 1 extend continuously through the entire machine room.
  • the air outlets 4 in the example shown by three — are sealed with air-permeable covers 5 that are flush with the floor of the machine room, while the air outlet “channels” between the covers 5 are covered with closed cover plates 15.
  • each air outlet 4 opens into the space 6 under the weaving machine in the area between the shafts 7 and the goods tree 12.
  • the space 6 is upward through the central support 9 of the weaving machine 3 and against the fabric tree 12 by a flexible element, for example made of a plastic film Apron 10 limited.
  • the space 6 becomes a storage space for the blown-in air.
  • Through openings 13 in the dust collecting plate 8 ensure that the air blown into the space 6 can not only flow under the dust collecting plate 8 to the warp beam 14, but also reaches the area of the shafts 7 on the warp beam side.
  • FIG. 3 the structure of the cover 5 for the air outlet 4 is shown enlarged.
  • a shoulder 17 widening the width of the air outlet 4 at floor level in the floor 1 is provided with a floor frame 16 formed by an angle iron, which is anchored in the concrete of the floor 1.
  • a base frame 19 rests via sealing elements 18, in which a screen fabric 21 is clamped by means of a fastening frame 20.
  • the width of the fabric of the screen fabric 21 is chosen - relative to the width of the frame 19, 20 - such that the fabric 21 bulges outward in the case of excess pressure in the air outlet 4, thereby improving the distribution of the blown air to the left and right.
  • the fabric 21, which can also be replaced by another element, for example a cambered plate provided with fine pores, forms a multiplicity of fine outlet openings 22, through which the air in thin and "gentle" rays emerge into room 6.
  • the fabric 21, for example a commercially available screen fabric is made of polyamide.
