Definitions

  • the invention relates to a cleaning device for a spinning preparation machine according to the preamble of claim 1.
  • the air is blown out through hoses with nozzle openings, which are connected to the compressed air network of the spinning mill. It is cleaned almost unthrottled with the pipeline system pressure of 6 bar.
  • the purpose of blowing is to whirl up the fiber deposits and then suck them off from the many suction points inside the machine or the spinning mill building. With this process, 100% of the fiber waste can never be removed.
  • Another disadvantage is that the fiber waste is blown into nips and other openings not intended for this purpose. This means that critical points are unnecessarily burdened with dirt deposits.
  • Vacuuming the machine is much more effective in terms of cleaning technology.
  • the fiber deposits are disposed of directly.
  • a longer hose is connected to the mandatory machine suction or hall suction, or an existing suction hose from the respective spinning preparation machine is used, clamped on one connection side from the associated suction point and this hose is handled like a vacuum cleaner.
  • the fiber accumulations are placed directly on the spinning mill's waste filter and disposed of accordingly.
  • the disadvantage of this process is the low vacuum available in the machine suction. This negative pressure has been reduced significantly over the past 30 years due to various energetic developments. In the past up to 2000 Pa (0.02 bar) negative pressure was available, today 300 to 500 Pa (0.003 - 0.005 bar) negative pressure are more common. With this negative pressure it is hardly possible to clean thoroughly.
  • the spinning mill operator can also purchase industrial vacuum cleaners for cleaning.
  • These vacuum cleaners are self-sufficient and only require a power connection. Due to the amount of dirt, you have large filter bags and a correspondingly high negative pressure (approx. 3000 Pa) available.
  • the disadvantage of this cleaning technology is the temporary storage of waste in the filter bag and the handling of the relatively large and heavy vacuum cleaner itself.
  • the FR 643.991 shows several cards arranged in a row, each with a suction area for dirt and separated fibers.
  • the suction areas are connected to a manifold line under negative pressure via hose lines.
  • a device for evacuating contaminants is disclosed, using either compressed air or a Fan is operated.
  • the device can be connected to a delivery line under negative pressure.
  • the DE 3514710 A1 shows a movable carriage coupled to a suction channel, on which different hoses for cleaning textile machines can be arranged.
  • the EP 0753612 A1 discloses a fixed suction device on a route in which a flexible suction hose can be acted upon by a fan with suction air.
  • the invention solves the problem posed by the teaching of claim 1; further advantageous design features of the invention are characterized by the subclaims.
  • the cleaning device comprises a suction tube with which dust, fibers or dirt is sucked in via a pressure booster.
  • the invention is characterized in that the dust, fibers or dirt can be transported away directly or indirectly via a suction channel of the spinning preparation machine.
  • the dust, fibers or dirt is fed into the suction channel by means of a suction hose.
  • the cleaning device according to the invention in the mobile embodiment has the advantage that it can be connected to different spinning preparation machines, so that only a few cleaning devices are necessary for each spinning operation.
  • the mobile embodiment can comprise a housing for the cleaning device which is provided with wheels, rollers or sliding elements.
  • a pressure chamber is arranged between the pressure booster and the suction hose, which is at least partially separated from the pressure booster by a partition. Heavy foreign parts, for example pieces of metal, which are sucked in through the suction pipe, can be deposited in the pressure chamber.
  • the pressure chamber of the cleaning device can be made relatively small, so that the cleaning device can be built compactly and the handling is simplified for the employees of the spinning mill.
  • the pressure booster is designed as a radial compressor.
  • a centrifugal compressor has the advantage of being inexpensive to manufacture.
  • the pressure booster preferably generates a negative pressure of greater than 0.03 bar up to 0.25 bar, preferably from 0.1 bar to 0.25 bar, on the suction side in the suction pipe. Since this negative pressure is many times higher than the negative pressure of the suction system of the spinning mill, the spinning preparation machine can be cleaned very efficiently even in inaccessible places.
  • the pressure booster Because the pressure booster generates an overpressure of up to 0.2 bar on the pressure side in the pressure chamber or in the suction hose, the suctioned dirt is reliably conveyed into the suction system of the spinning mill.
  • the device is mobile or can be integrated into a spinning preparation machine.
  • the mobile version can be used for the entire spinning mill, so that the operator only has to purchase a few cleaning devices.
  • the integrated cleaning device can be designed as a component of any spinning preparation machine, in which, for example, the suction pipe can be removed and hung on the inner surface of a housing door.
  • the spinning preparation machine is advantageously designed as a card, draw frame, winding machine, combing machine or blowroom machine.
  • FIG. 1 shows a card 10, the housing 20 of which is mainly made of sheet metal and is essentially closed on all sides.
  • Air inlet openings 22 to 26 suction openings

  • a central suction channel is designated by 27, which is connected to a suction source (not shown) of the spinning mill.
  • suction hoods 19a to 19f there may be six suction hoods 19a to 19f, each of which has an open face forming an air inlet opening and the other face of which is connected to a common collecting line 28 which leads to the central suction channel 27.
  • the direction of the air currents is indicated by arrows E, F, G.
  • the supply air flows E, E 1 , E 2 enter the open air inlet openings of the suction hoods 19a to 19f by suction, flow through the suction hoods 19a to 19f as air flows F and emerge from the end openings of the suction hoods 19a to 19f and at the same time as exhaust air flows G.

  • the housing 41 can be provided with wheels, rollers or sliding elements in a mobile manner.
  • the pressure booster 42 can also be designed as a separator or cyclone for generating the negative pressure, in which case the Air duct in the cleaning device 40 must be designed differently.
  • the pressure booster 42 preferably generates a pressure difference or a negative pressure of up to 25 KPa (0.25 bar) on the suction side, which corresponds to a multiple pressure difference of the suction channel 27. This creates an overpressure of approx. 10 to 20 KPa on the pressure side, which ensures that the fibers and dust are conveyed through the suction hose 46 into the suction channel 27.
  • the cleaning device according to the invention in this embodiment has the advantage that it can be connected to any spinning preparation machine in a mobile manner.
