Definitions

  • the present invention relates to a method for cleaning spinning rotors for open-end spinning, each rotor of which is located in a rotor housing with a rotor housing opening provided for external suction, in which method the rotor housing of the rotor to be cleaned is opened and opened by a this rotor housing mounted cleaning device is covered, and the cleaning device generates by means of a rotatable blower body at least one rotating air jet which essentially acts on the collecting groove of the rotor.
  • German Offenlegungsschrift No. 26 48 066 shows a method in which a rotating cleaning brush is immersed in the rotating rotor for carrying out the rotor cleaning and comes into contact with its inner surface and in particular also with the collecting groove.
  • a flexible probe is provided as a mechanical cleaning element for moving into the spinning rotor to be cleaned.
  • the relatively strong adhesion of the contaminants due to the centrifugal force plays a subordinate role.
  • the wear of brushes is relatively high.
  • the invention also relates to a cleaning device for carrying out the method, which comprises a cleaning cover which can be placed on the rotor housing of the rotor to be cleaned and the rotatable blow head, the axis of rotation of which essentially coincides with that of the rotor, and which is characterized in that a through the cleaning cover Suction channel is provided that the blow head parallel to its axis of rotation from its working position, in which its end facing the rotor is located near the free edge of the rotor and with its free edge forms the round gap, in a second working position, in which the blow head is immersed in the interior of the rotor, is movable, and that it has at least one cleaning channel which serves to generate an air jet and which is connected to a compressed air line which is used for the optional supply of Compressed air is used for the cleaning duct.
  • the thorough cleaning resulting from this invention is essentially due to the fact that the fibrous impurities accumulated in the collecting groove are transported away by the suction process that occurs first and then the relatively strongly adhering impurities consisting of fine dust particles through a sharp, ie the shortest possible jet should be blown away. In this way, a cleaning process that is specific and effective for each type is provided for both types of impurities.
  • a spinning rotor 11 is shown, which is rotatably supported by an axle bearing 12.
  • the spinning rotor 11 is located inside a rotor housing 13.
  • the latter is open with a rotor housing Provide 14, which is provided in normal operation for the external suction for sliver conveyance.
  • the rotor housing 13 is normally closed with a cover during operation. In the drawing, however, this cover is not shown and a cleaning device 15 is placed on the rotor housing 13 in its place.
  • the device 15 comprises a suction line 16, a cylinder 17, a blow head 18 and a cleaning cover 19. The latter can be placed on the open rotor housing 13 with a tight fit.
  • a cleaning channel 25 for generating an air jet which ends at one end in a longitudinal bore 26 provided in the shaft 21.
  • drive channels 27 formed by air lines are provided, which serve to set the blow head 18 in rotation.
  • the channels 27 extend radially outward from the longitudinal bore 26 in opposite directions and bend at right angles to the cylindrical surface of the blow head 18 in mutually opposite directions. As shown in FIG. 3, these angled channel sections 27 'of the drive channels 27 run out at their exit point the blow head 18 approximately tangential to its surface.
  • the air emerging from the duct pieces 27 'must have at least one movement component tangential to the surface of the head 18 in order to be able to set the blow head 18 in rotation.
  • FIG. 3 of a blow head 18 in a plane perpendicular to its axis of rotation and thus also to the shaft 21 shows a possible arrangement of channels.
  • a single cleaning channel is not provided, but there are three cleaning channels 25 arranged around the longitudinal bore 26 at equal angular distances from one another, all of which essentially against the collecting groove 32 of the spinning rotor 11, which is particularly soiled by pieces of fiber and dust particles is exposed.
  • cleaning channels 33 designed as air lines can additionally be provided. These serve to give the rotor edge 34 of the rotor 11, to which fibers adhere relatively strongly, a particularly vigorous cleaning.
  • the cleaning channels 33 are directed towards the edge 34.
  • On the end face of the cylinder 17 facing away from the blow head 18 there is a compressed air line 29 which serves for the optional introduction of compressed air into the interior of the cylinder 17.
  • the air jet is sharper the shorter it is.
  • the air outlet points of the channels 25 are located on the lateral surface of the blow head 18, which in the example shown is of essentially circular cylindrical shape. Therefore, if the diameter of the lateral surface is chosen to be as large as possible so that the space between it and the rotor edge 34 is small, the air outlet points are brought so close to the parts of the rotor 11 to be cleaned, in particular to the collecting groove 32, as this is practically possible.
  • a further improvement in the cleaning of the rotor 11 is obtained if the strength of the rotating air jet is varied, in particular if it is formed by successive air pulses.
  • three successive blowing pulses are generated for cleaning the rotor 11.
  • the duration of these blowing pulses or the duration of the generation of each of these pulses is between 0.3 and 1.5 seconds and the pauses between the blowing pulses are between 0.2 and 0.4 seconds.
  • a pulsating air jet has a stronger cleaning power than an air jet of the same size but of constant strength.
  • a pulsating air jet in the example shown in FIGS. 1 and 2 also causes a reciprocation of the piston 23 in the cylinder 17 and thus a change in the immersion depth of the blow head 18 in the rotor 11.
  • This change in the immersion depth causes, in addition to the effect of pulsating air jet, a further, additional improvement of the Cleaning, so that in the embodiment of FIGS. 1 and 2, the pulsating air jet is of very particular advantage.
