Definitions

  • the invention relates to a cleaning device for a spinning preparation machine, according to the preamble of claim 1, a spinning preparation machine, and a method for cleaning a spinning preparation machine.
  • the blowing out takes place through hoses with nozzle opening, 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. By blowing the fiber deposits are whirled up and then sucked from the many extraction points within the machine or the spinning mill building. None 100% of fiber waste can be removed with this process. Another disadvantage is that the fiber waste in nips and other not intended Openings are blown. Critical areas are unnecessarily burdened with additional dirt deposits.
  • the spinning mill operator can purchase industrial vacuum cleaners for cleaning.
  • These vacuum cleaners are self-sufficient and only require a power connection. Due to the amount of dirt they have large filter bags and a correspondingly high negative pressure (about 3000 Pa) available.
  • the disadvantage of this cleaning technology is the intermediate storage of the waste in the filter bag and the handling of the relatively large and heavy vacuum itself.
  • the cleaning device comprises a suction pipe, with which dust, fibers or dirt is sucked in via a pressure booster.
  • the invention is characterized in that the dust, the fibers or the dirt can be transported away directly or indirectly via a suction channel of the spinning preparation machine.
  • the dust, fibers or dirt can be introduced into the suction channel by means of a suction hose or by means of a suction tube.
  • the cleaning device according to the invention in the mobile embodiment has the advantage that it can be connected to various spinning preparation machine, and thus for each spinning operation only a few cleaning devices necessary are.

  • the mobile embodiment may also comprise only one pressure amplifier, which is insertable into a receiving device of the suction duct or an air duct. In this case, in the region of the suction side of the booster, the suction pipe can be connected to the suction duct or to an air duct.
  • a pressure space between the pressure booster and the suction hose can be arranged, which is at least partially separated from the pressure booster by a partition wall.
  • heavy foreign parts, such as pieces of metal, are deposited, which are sucked through the suction pipe with.
  • the pressure chamber of the cleaning device can be made relatively small, so that the cleaning device can be made compact and handling for the employees of the spinning is simplified.
  • the cleaning device can be constructed without a pressure chamber, with the pressure side of the pressure intensifier conveying the fibers, the dust and the dirt directly into the suction hose.
  • the pressure intensifier is designed as a radial compressor.
  • a radial compressor has the advantage of cheap manufacturability.
  • the pressure intensifier generates on the suction side in the suction pipe a negative pressure of greater than 0.03 bar up to 0.25 bar, preferably from 0.1 bar to 0.25 bar. Since this negative pressure is many times higher than the negative pressure of the extraction system of the spinning mill, the spinning preparation machine can be very efficiently cleaned even in inaccessible places.
  • the pressure intensifier on the pressure side in the pressure chamber or in the suction hose generates an overpressure of up to 0.2 bar, the extracted dirt is reliably conveyed into the extraction system of the spinning mill.
  • the device is mobile or can be integrated into a spinning preparation machine.
  • the mobile embodiment can be used for the entire spinning, so that the operator has to purchase only a few cleaning devices.
  • the integrated cleaning device can be implemented as part of any spinning preparation machine in which, for example, the suction tube is removable and can be suspended on the inner surface of a housing door.
  • the spinning preparation machine has at least one cleaning point for dust, fibers or dirt, which can be placed under a suction air flow, wherein the suction air flow is directly or indirectly connected to a suction channel of the spinning mill.
  • the spinning preparation machine is characterized in that a closable connection is arranged on the suction channel, to which the suction hose or the suction pipe of a cleaning device can be connected.
  • the spinning preparation machine can be cleaned with a mobile or integrable cleaning device that promotes the sucked dirt in the extraction of the spinning.
  • the cleaning device is integrated into the spinning preparation machine, so that each spinning preparation machine has its own cleaning device.
  • the pressure booster of the cleaning device is arranged within a suction duct or air duct or a collecting device.
  • the connection is arranged, to which the suction pipe can be connected.
  • the spinning preparation machine may have a receiving device in the suction channel or in an air duct into which the pressure booster can be inserted.
  • the cleaning device can be used flexibly for several spinning preparation machines.
  • the suction pipe in the region of the suction side of the booster, can be connected to the suction duct or to an air duct.
  • the cleaning point for dust, fibers or dirt with at least one manifold or an air duct is connected to the suction channel.
  • Each of the manifolds or the air tubes is adapted to receive the sealable connection.
  • the arrangement of the closable connection to one of the manifolds or air pipes has the advantage of easy accessibility, since they are often at working height.
  • the at least one collecting line preferably leads into a collecting device.
  • the attachment of the closable connection to the collecting device has the advantage that a higher negative pressure is applied here than at the individual cleaning points or the manifolds or air pipes.
  • the spinning preparation machine is designed as a card, route, winding machine, combing machine or cleaning machine.
