Definitions

  • the invention relates to a machine for producing twisted or twisted threads, with at least one electric motor, which is at least partially surrounded by a housing.
  • the heat collecting bells depending on the material processed, the heat collecting bells sometimes have a strong tendency to become contaminated by flight and dust, which hinders the air throughput and thus impairs the effectiveness of the heat collecting bells.
  • the present invention is therefore based on the object of providing a construction of the type mentioned at the outset in which contamination of the housing is avoided in a simple manner.
  • At least one blowing nozzle which temporarily applies a blowing flow to the interior of the housing.
  • This has the advantage that the interior of the blowing nozzle is acted upon by blowing current, so that contamination or flying of the interior of the housing is avoided.
  • These housings which are designed, for example, as heat collection bells, can preferably be in the interior from time to time in the upper region For example, every ten minutes, for a short time, for example for two seconds, a stream of blown air is applied, through which dust or flight deposited in the heat collecting bell or on the motor dissolves and either is sucked off into the thread breakage suction or blown out of the heat collecting bell.
  • a large number of work units 1 are arranged on each machine side.
  • machine elements to be understood at high speed in the following, for. B. spindles on spinning or twisting machines or rotors or opening rollers on OE spinning machines.
  • These work units can have spindles 2, for example, which are each driven via whorls 3 by tangential belts 4 and 5.
  • the tangential belts run over deflection roller elements 6 and 7 and are driven by motors 9 via a drive pulley 8.
  • each of the drafting systems there are drafting systems above the working units 1, the last pairs of rollers 10 of which are shown schematically.
  • a suction port 11 which is open at the front and which leads to one of two thread breakage suction channels 12 and 13 which are arranged on each side of the machine and extend longitudinally thereto.
  • Each of the motors 9 is surrounded by a heat collecting bell 14, which merges from a bell-shaped upper area into a cylindrical area 17. From this upper area of the heat collecting bell 14, branch pipes 16 lead into the yarn breakage suction channels 12 and 13, through which warm air accumulated in the heat collecting bell is sucked off.
  • a blowing nozzle 20 is arranged in the upper region of the heat collecting bell 14 and is connected via a line 21 to a pump 22 which is driven by a motor 23.
  • the blower nozzle 20 By means of the pump 22, compressed air is fed to the blower nozzle 20 via the valve 25 and via the line 21, as a result of which blast air flow is applied to the interior of the heat collection bell 19 after opening of the valve 25 and thus accumulates in the interior 19 of the heat collection bell 14 or on the motor 9 Dust and flight dissolves. These impurities can either be sucked into the thread break suction channel 12, 13 or blown out of the heat collecting bell 14.
  • the blowing nozzle is arranged in the upper region of the heat collecting bell 14 and in such a way that the air flow is directed against the motor 9 and the inner wall of the heat collecting bell 14. In this way, the heat collection bell 14 is protected from contamination and flying in a simple manner.
  • FIG. 2 between two rows of spindles 1, which are mounted on spindle banks 40, there is at least one motor 9, which is provided with a fan cover 30.
  • a cover 31 is located below the fan cover 30.
  • the entire unit is surrounded by a housing 14.
  • the air flow via the blowing nozzles 20 temporarily acts on the interior 19 of the housing 14, which in turn also protects the housing from dirt and flying in a simple manner.
  • the timer 24 controls both the intervals between the opening phases and the duration of the opening phases of the valve 25 so that a good adaptation to the prevailing situations is possible. If it should be shown that not all areas of the heat collecting bell are cleaned adequately, because the blowing stream of a blowing nozzle does not reach all areas sufficiently, further blowing nozzles can be arranged accordingly. In this case, the timer 24 advantageously keeps these several blowing nozzles open in a staggered manner in time. The same applies if machines or machine groups are equipped with several heat collecting bells.
  • the blown air flow has proven to be particularly effective when it is introduced abruptly under high pressure, for example 6 bar. Such a blast of compressed air is evidently strongly swirled when it encounters an obstacle, for example the motor 9. These vortices, which move in different directions, are particularly effective in removing deposits of dust or flight inside the heat collection bell.
