Definitions

  • the invention relates to a method for influencing the air conditioning of the fibers processed in a spinning machine, by supplying air with a predetermined moisture and temperature into a predetermined mass of fibers.
  • the clumping of fiber flakes in a pneumatic transport air stream can, however, also occur when the fiber flakes are too high.
  • Patent specifications No. 516 660 and No. 506 640 of the applicant regulate the transport air humidity between the last cleaning machine and the card feed shaft, so that the moisture of the fibers in this transport air stream can be optimally maintained.
  • the fibers pass from the transport air flow into a feed shaft, in which the transport air is separated from the fibers on the one hand and, at the same time, the fibers are compressed in the feed shaft.
  • a fiber wadding is formed in the exit of this feed shaft, which is fed to the card feeder via a feed table.
  • These air flows essentially have air conditioning, which is related to the climatic conditions of the ambient air.
  • the invention solves this problem, for example, in that the conditioned air is input shortly before and / or in the spinning machine and in that this conditioned air is conducted into and through the predetermined mass of fibers.
  • the advantages of these inventive steps are that the fibers are optimized for processing with regard to suppleness and the cleaning effect of the fibers is optimized with regard to dirt release. This improves the so-called running behavior of the spinning machine, because it enables the individual machines to work under optimal climatic conditions. Running behavior means the trouble-free running of the spinning machine.
  • FIG. 1 shows a pneumatic flake conveyor system of the CH-516 660 with a filling shaft 7 and a card 8.
  • a flake feeder 1 receives pneumatically conveyed fiber material via a feed line 2. The flakes are sucked away from the flake feeder 1 through a line 3 into which a fan 4 is inserted, together with the transport air in the direction of arrow L, and pass under pressure in the direction of arrow M through a line section 5 into a high-level transport line 6 .
  • the transport line 6 ends at the filling shaft 7 of the card 8.
  • the transport air entering the filling shaft 7 flows through an air-permeable partition 9 located on the filling shaft 7 into an outflow shaft 10 and further in the line 11 into a room under a lower pressure (not shown).
  • a plurality of filling shafts 7 can also be connected in series to the transport line 6, in which case the filling shaft 7 shown here in FIG. 1 is the last one.

  • the commercially available sensor 15 measures the moisture and temperature in the flock-laden transport air stream and can trigger a release of water vapor via the control member 14, which can reach the line 3 through the opening 17.
  • FIG. 2 shows a card feed 20 with a filler shaft 21, into which a filler line 22 opens and an exhaust duct 24 with an exhaust duct 25.
  • a perforated wall 23 forms the air-permeable connection between the filler duct 21 and the exhaust duct 24.

  • a carding tape 68 produced by the card is then placed in a tape storage 69.
  • three air conditioning units are provided which can be operated as individual units or, as described later, can be replaced by a single air conditioning unit.
  • the first air conditioning unit is the one that holds the fibers in the feed shaft 28, the second one that the fibers in the fiber mat on the inlet table 43 and the third one that influences the climate of the card.
  • An air conditioning system 39 is provided for the first unit, from which an air supply line 54 opens into a fan 37, which emits its air by means of a connecting pipe 29 into an air distribution box 30, which is seen at the upper end of the feed shaft 28 with a view of FIG Dining shaft is provided.
  • the air from the air distribution box 30 enters through a perforated wall 31 of the feed shaft 28 into the interior of the feed shaft 28.
  • This air-conditioned air blown in flows through the fiber flakes located in the feed shaft 28 and exits mostly through a lower perforated wall 32 of the feed shaft 28, namely into an air collecting space 34, from which the air is led back into the air conditioning system 39 via an exhaust air line 35 .
  • This air circulation is caused by the fan 37.
  • a measuring sensor 41 is provided in the exhaust air line 35 for measuring the relative air humidity and the air temperature, which emits a signal 36 to a control element 40 which controls the air conditioning system 39 via the control line 38.
  • the perforated wall 32 is provided with cover slats on the side lying against the interior of the feed shaft 28, so that as far as possible no fibers can pass through the perforation of the perforated wall 32.
  • the second unit relates to the air conditioning of the fiber mat on the inlet table 43, for which purpose an air conditioning system 48 is connected by means of a supply air line 55 to a fan 58 which emits the air flow generated via a connecting pipe 46 into a housing 45 in which a perforated area 44 of the Inlet table 43 is located.

  • the fan can, as indicated by the fan 58.1 drawn with dash-dotted lines, also be provided after the housing 45.

  • both air conditioning units are closed systems, it is advantageous if the air conditioning units 48 and 39 receive the air escaping from their system. Compensate additionally taken over air with atmospheric air. However, such systems are known per se and are common for air circulation systems.
  • the third air conditioning unit concerns the card. To create an actual card climate, it is necessary to enclose the card in a card housing 70, so that the air conditioned by an air conditioning system 76 cannot essentially escape into the atmosphere.
  • This conditioned air passes through a supply air line 79 into a fan 74 and from there via a connection 71 into the space closed off by the housing 70.
  • the air in the exhaust air line 72 is measured by a sensor 78 which is analogous to the sensor 41 and the result is given as a signal 73 to a control element 77 which controls the air conditioning system 76 via a line 75.
  • the climate that determines the running behavior of the card is primarily that around the reel 63 of the card 60, since the card feed, in a manner known per se, dissolves the fed-in fiber flakes into a very thin fiber layer and feeds them to the reel, so that the ambient air of this fiber lily is significantly involved in the air conditioning of this fiber lily.
  • This means that the air conditioning in front of the card is not useless and ineffective, but has a more limited influence on the running behavior of the card than the climate in the card itself.
