Definitions

  • the air is sucked in from the surroundings of the spinning station through openings into the interior of a housing and, if necessary, filtered by means of a suction fan.
  • Appropriate baffles are arranged to guide the air flow into the interior of the housing and inside, but it has been found that the impurities are deposited in dead corners and angles. This has a disruptive effect on the operation of such thread and flight extraction systems.
  • the cross section of the openings, suction channels or the like can be changed at least partially and / or temporarily during the spinning process.
  • the change in the cross section of openings or intake ducts causes a change in the air flow and also in the formation of eddies in the interior of the housing, so that deposits of contaminants in dead corners and angles are avoided.
  • Flight extraction in the area of the spinning position on the head sleeve is particularly important, i.e. in the balloon area.
  • an intake duct should preferably be assigned to a lower region and an opening to a middle and upper region of the head sleeve.
  • the intake duct and the opening are formed by appropriate baffles.
  • a further guide plate, which holds a thread guide, is preferably assigned to the last-mentioned opening, the guide plate being arranged such that it can be changed in position.
  • the thread guide is raised during the spinning process with the formation of a cop, so that this lifting also follows the guide plate.
  • the cross section of the opening is released more and more during the spinning process.
  • the present invention takes advantage of motion sequences which in any case take place in the spinning device.
  • This also means that at the beginning of the spinning process, there is an increased intake of air through the lower intake duct, which at this time is closest to the spinning position. If the spinning station moves upwards along the cop sleeve, the opening is also increasingly opened, the spinning station getting closer to this opening. By opening the opening, the air flow in the lower intake duct is reduced, which is irrelevant, however, since the spinning station moves away from this intake duct at the same time.
  • the baffle profile has at least one flow opening, which in turn is approximately aligned with the lower intake duct in the lower position of use and with the central opening in a middle to upper position of use.
  • This flow opening creates a concentration of the air flow, which leads from the spinning station through the flow opening and into the lower suction channel or the middle opening. This improves the suction process.
  • FIGS. 2 to 4 parts of a ring spinning machine are shown schematically. Head sleeves 2 are arranged on both sides of a housing 1 on spindle banks 3 shown in FIGS. 2 to 4.
  • the left-hand head sleeve 2 is only partially covered with a thread 4 shown in broken lines, while a perfect head 5 is already formed on the right-hand head sleeve 2.
  • There the thread runs from a drafting system 6, which is only indicated by drafting cylinder 7, through a thread guide 8 ("Sauschwänzli”) and through a spinning ring 9 to the head sleeve 2.
  • the spinning ring 9 is connected to a ring frame 10, which in turn in the direction x can be moved along an axis A of the cop sleeve 2.
  • This ring frame is on the left side in its lower position of use, while it is arranged on the right side in its upper end position. While the head sleeve 2 is being coated with the thread 4, the ring frame 10 moves in the direction x, as a result of which a predetermined, desired winding of the thread 4 on the head sleeve 2 takes place.
  • the thread guide 8 which is fixed to a thread guide guide plate 11, also moves in the direction x during the winding of the thread 4, but its movement does not take place to the same extent as the movement of the ring frame 10. This is also clear when comparing the left recognizable with the right-hand position of use in Figure 1.
  • the thread guide baffle 11 closes a central opening 12, while it is released in the position of use shown on the right.
  • the central opening 12 is formed between a lower guide plate 13 and a front guide plate 14.
  • the front guide plate 14 engages under the drafting device 6 with a leg 15, wherein it forms an intake duct 18 together with a guide plate 17 provided under a cleaning device 16.
  • Another passage in the intake duct 18 between the baffle 17 and a baffle hood 19 is identified by 20.
  • a lower intake duct 22 is formed between the lower guide plate 13 and a guide plate bench 21, which is assigned to the lower part of the head sleeve 2.
  • a balloon limiter 28 is connected to the ring frame 10 via a guide plate profile 29.
  • baffle profile 29 there is a further flow opening 30 which, in the lower position of use of the ring frame 10, is assigned to the lower intake duct 22.
  • the thread guide baffle 11 closes the central opening 12 so that the essential air flow from the head sleeve 2 flows through the flow opening 30 into the lower intake duct 22.
  • the ring frame 10 moves in the direction x along the axis A of the head sleeve 2, this movement also being followed in a weakened form by the thread guide guide plate 11.
  • the central opening 12 is slowly released, so that, as shown in FIG.
  • the flow opening 30 is also rather associated with the central opening 12, so that an increased air flow always flows into the interior of the housing precisely at the spinning position itself. This means that the strongest air flow takes place at the point where the greatest contamination occurs.
