Definitions

  • the invention relates to a method and an apparatus for manufacturing of compacted yarn, in which after warping a fiber sliver this is compressed by means of suction air flow and then rotated.
  • the object of the present invention is a method or to create a device with which the device on the Presence of suction air flow is monitored to ensure yarn quality and the full effectiveness of the device for producing compacted Maintain yarn.
  • Monitoring is carried out using measurement methods customary in flow technology for measuring pressures or flow velocities like pressure probes, Anemometers or similar sensors.
  • a response of the measuring device can when a fixed, adjustable threshold value is exceeded and / or fallen below or if there is an overdue departure from at least one other Suction point immediately follow the prevailing value.
  • the device for producing compacted yarn which with at least a drafting device for drawing the fiber sliver, with at least one suction device for compacting the fiber sliver by means of suction air flow and with at least a twisting device can be designed so that at least one of the suction devices with a device for detecting the Suction air flow is provided, which with a comparison unit with a Evaluation unit is connected.
  • This facility for capturing the Suction air flow can be arranged in the suction line of the respective suction device his.
  • the evaluation unit can act as an alarm and / or shutdown device or be designed as a display device.
  • the device for manufacturing shown schematically in Fig. 1 in side view of compressed yarn from a fiber sliver 1 has e.g. a first pair of rollers 2 and a downstream second pair of rollers 3. Between the two The fiber sliver 1 can experience a pre-delay in the roller pairs 2 and 3.
  • the Roller pair 3 can be equipped with straps 4 and 5, which Upper straps 4 stretched by a strapping cage, not shown and the lower strap 5 can be guided over a support rail 6. This Rail 6 can also serve to support the top strap 4.
  • the second pair of rollers 3 is followed by an output pair of rollers 8.
  • On this pair of output rollers 8 is followed by a fiber bundling zone 20, in which the finished warped fiber sliver emerging from the pair of output rollers 8 1 is summarized transversely to the transport device.
  • the fiber bundling zone 20 has a suction device 12 with a perforated one Straps 15, which around the top roller 10 'of a pair of delivery rollers 10th is led.
  • the perforation of this strappy 15 consists of a number in Running direction of the fiber sliver 1 of small openings lying one behind the other, e.g. side by side and / or one after the other.
  • the perforated strap 15 is guided around a strap cage 16, which via a suction line 22 in connection with a suction unit, not shown stands.
  • a suction air flow S achieved, which serves to compress the fiber sliver 1.
  • the fiber sliver 1 thus processed is not replaced by one Twisted device shown in more detail rotated, for example by a ring spinning device.
  • the suction device 12 is according to the invention according to FIGS. 2 and 3 with a device 25 or 25 'for detecting the suction air flow S.
  • This facility 25 is in a comparison unit 30 with an evaluation unit 40 in Connection.
  • the device 25 for detecting the suction air flow S according to FIG. 2 have a measuring tube 27 which is directly in the housing of the strappy cage 16 leads, which is part of the suction device 12.
  • the flow velocity of the air becomes a sensor, not shown, common in flow technology, z. B. hot wire anemometer measured.
  • This threshold can be adjustable, for example in the area of the comparison unit 30 to make an appropriate adjustment to the respective yarn quality of the fiber sliver 1 can make.
  • the evaluation unit shown only schematically 40 can be used as an alarm and / or storage device or as a display device be trained.
  • the total pressure, the static pressure and / or the dynamic pressure or the flow velocity measured in the air With the help of the measuring tube 27 and sensor (not shown), the total pressure, the static pressure and / or the dynamic pressure or the flow velocity measured in the air.
  • the embodiment of a device for the production of compacted yarns 4 differs from that of FIG. 1 in that in the second Embodiment used as a suction device 12 'a perforated suction roller which is rotating.
  • This rotating, perforated suction roll works with two Counter rolls 13 and 14 together to form the warped fiber sliver 1 To compress suction air flow.
  • a first pair of rollers 2, 1 second pair of rollers 3 and a pair of output rollers 8 are provided.
  • the Suction air flow monitored when falling below a threshold issued a message via the comparison unit 30 and the evaluation unit 40 which triggers an error and / or shutdown signal.
  • the Threshold value adjustable with the total pressure, the static pressure, at each suction point Pressure or the dynamic pressure is measured.
  • the evaluation unit 40 can be used as an alarm and / or shutdown device or as Display device may be formed.
  • the present invention shows that in a simple manner the suction air flow is monitored to ensure the yarn quality in every case.
