Definitions

  • the present invention relates to a closed creel with coil carriers arranged around at least one essentially vertical central axis and a device for generating an air flow in the creel.
  • Bobbin creels with bobbins arranged in a row or around a central axis are used in the textile industry to hold yarn bobbins, a large number of yarn bobbins being unwound simultaneously and at high speed, in particular for processing the yarn in knitting machines.
  • a creel of this type is shown in European Patent Application No. 0160 231.
  • the fiber fly resulting from the unwinding leads to various problems: The fibers flying around are entrained by the unwound threads or are deposited on the reserve spools, which leads to knitting errors, thread breaks and needle breaks.
  • creels are provided with fans that keep the bobbins and unwinding paths free of fiber fly.
  • the blown away fibers contaminate the room air and are also deposited in inaccessible places (e.g. under the machines).
  • a closed creel is known in which fans are provided on one side, with which filtered room air is sucked in and blown out on the opposite side with simultaneous filtering ("knitting and knitting technology" 37 (1987) 9/981).
  • the result of this is that disruptive air currents are generated in the room, especially in the case of several such coil gates.
  • To ensure a uniform air flow in the creel is also a uneconomically high number of fans required.
  • the main advantages of the invention are that on the one hand a sufficiently high air throughput can be generated in the creel to eliminate the fiber fly and on the other hand the risk of thread entanglement of loose threads and thread connections through air swirls is avoided, since only a part of those from the outer area the air drawn off the creel is returned to this area as circulating air.
  • the arrangement of the coil carriers around a central axis ensures both a uniform formation of the air flow and an inexpensive construction with e.g. a single fan.
  • the exhaust air can be released to the room in a controlled manner.
  • This configuration of the bobbin case allows, in a preferred embodiment, the operation to be maintained during the exchange of the bobbins, in that lateral walls of the bobbin case are designed as doors and the bobbin carriers can be swung out with the doors, a thread guide element for thread deflection ensuring that the Threads can be unwound even when the doors are open.
  • the swing-out bobbin carriers also provide good access for changing bobbins.
  • a creel with an upper 1 and a lower cover 2 and with side walls 3 is shown.
  • the top and bottom cover are circular or regularly polygonal (12-cornered in the selected illustration).
  • Bobbin carriers with yarn bobbins 13 are arranged around a vertical central axis 11.
  • the coil carriers consist of coil support rods 12, which are attached above in pairs and freely suspended on radially extending slide rails 15.
  • the side walls 3 are provided with doors 4 or are formed directly through these doors. Thanks to the slide rails 15, the bobbin support rods 12 can be pulled out when the doors 4 are open, so that the bobbins 13 are freely accessible (cf. FIG. 2) and can be replaced without problems.
  • the yarn 14 to be processed is unwound radially from the bobbins 13 against the central axis 11 and guided via yarn tubes 16 to a circular knitting machine (not shown) located next to the bobbin creel. Sealing pipe guides 17 in the upper cover 1 ensure the use of the same creel in circular knitting machines of different heights.
  • the coil creel is through an air-permeable partition 5 concentric to the central axis 11, which preferably extends over the entire height of the coil support rods 12, in an outer region 6, which contains the coil carriers and divides an inner region 7.
  • a fan 8 arranged at the upper end of the inner region 7, air is sucked from the outer region 6 essentially over the entire height through the partition 5 into the inner region 7 (arrows A).
  • the partition 5 is preferably designed as a filter, so that the fiber fly occurring in the outer region 6 is deposited directly on this partition.
  • a filter cloth for example, is suitable as a filter, which can be cleaned periodically with a fur roller (by opening the doors 4).
  • a part e.g.
  • the remaining air is preferably directed upwards via a discharge opening 9 either directly or indirectly (e.g. via air conditioning) to the environment (arrows C).
  • the resulting air deficit in the outer area 6 is compensated by additionally sucking in ambient air from the surroundings (arrows D).
  • 4 air openings 10 are provided in the doors, which are provided with mesh filters, for example.
  • blow-out opening 9 is arranged at the top and directed upwards, the whirling up of dust and fiber fly in the surrounding space is prevented.
  • the air openings 10 are preferably arranged in the lower region of the doors 4, so that a continuous, largely uniform air throughput is achieved over the entire height of the coil support rods. Mechanical or electronic means can be used to ensure that the suction power of the fan is reduced when the associated knitting machines are down.
  • the side walls 3 or the doors 4 are preferably made of transparent material (e.g. plexiglass).
  • the outer area 6 of the creel can be divided into individual sectors by means of separators 18 which can be hung from top to bottom. This makes it possible to separate the fiber flight of differently colored yarns or different fiber materials.
  • FIG. 3 shows an exemplary embodiment of the invention, in which the bobbin carriers for each sector can be swung outwards as a unit 20 at full height and thus allow free access to the yarn tubes 16.
  • a vertically extending deflecting rod 21 is provided on the spool holder unit 20 as a thread guide element.
  • the thread guide element 21 ensures that the yarn can continue to be unwound from the bobbins 13 that are currently being operated, without excessive yarn deflection taking place.
  • the coils of the other row of coils can then be easily replaced.
  • the spool holder units 20 can preferably separated from the doors 4, but pivoted out with the same axis of rotation. The doors 4 can therefore be opened for certain manipulations without the spool holder units 20 having to be pivoted out.
  • the bobbin creel can be fully equipped with such bobbin carriers 20, which facilitates operability and thus permits a further increase in productivity.
  • only individual sectors can also be equipped in this way, while others are designed in accordance with the first exemplary embodiment. This is particularly the case if a company wants to continue using conventional coil support rods 12.
  • the yarn threads of a yarn bobbin are each guided over yarn tubes 16 at the top out of the creel to knitting machines.
  • the individual yarn tubes 16 are arranged in a cladding tube 22.
  • the cladding tube 22 can be, for example, a steel tube with a tube diameter of 30 mm and a wall thickness of 1 mm, in which several yarn tubes 16 are combined.
  • the upper cover 1 of the creel can be designed as a plastic film, for example as a reinforced PVC film, with openings 24 at the passage points for the yarn tubes, which are slightly smaller than that Diameter of the cladding tubes 22. These are pushed through the openings, the film sealingly engaging them, as indicated in FIG. 4. This means that the thread tube outlets can be sealed without effort and with a lightweight and inexpensive design, so that there is no leakage of unfiltered air contaminated with dust particles into the room.
  • the exemplary embodiments shown have an outer wall 3 which is essentially concentric with the central axis 11 as housing.
  • a plurality of coil gates of this type can also be in an essentially rectangular housing, e.g. with the floor plan dimensions 160x400 cm.
  • Each individual coil creel is then provided with the concentric fan and filter arrangement described and coil carriers arranged around it, but e.g. three such arrangements housed in the common rectangular housing, which is provided with doors and top and bottom covers.
  • the bobbins described allow the dust generated when the yarn is being unwound to be kept away from the ambient air without hindering the operating processes and without significant additional effort.
