Definitions

  • the invention relates to a rotary drive for a spinning rotor with the features of the preamble of the first claim.
  • DE 35 30 879 A1 describes one method and one Device for cleaning the rotor is known, a rotatable Blowing device is used, which with an otherwise also available in DE 26 29 161 C2 suction bell corresponds.
  • a rotatable Blowing device is used, which with an otherwise also available in DE 26 29 161 C2 suction bell corresponds.
  • the invention is characterized by the features of claims 2 to 11 advantageously trained.
  • the spinning rotor during the rotary drive for the Rotor cleaning exposed to no radial force when the axes of the rotary drive and the spinning rotor are aligned.
  • Possible minor adjustment errors are in the range of 1 mm and lead not yet to generate disturbing radial forces. You can for example, be intercepted by an appropriate game the suspension of the rotary drive or an elasticity of the Holding the driving elements or the driving elements itself. If necessary, also during the drive a mutual centering between the rotary drive and Spinning rotor done.
  • the entrainment elements can be made in one closed ring or from several driving elements, the are arranged on an arc. critical is that the ring or arc is perpendicular to the Rotor axis are arranged around the required centering to ensure. In any case, the arrangement should be chosen that no resulting radial forces remain.
  • the driving elements directly on the are advantageous electric rotor of the rotary drive attached, the is preferably designed as an external rotor motor.
  • Driving elements made of are particularly suitable elastic material to also ensure that on the cleaning tools arranged exactly the same feed element can be positioned so that they are on the rotor groove to meet.
  • the takeaway elements consist of so-called Rubber magnets, is not a contact pressure on the feed of the Rotor drive unit necessary if the ferromagnetic Spinning rotor by magnetic force with the driving elements is coupled.
  • Positioning device To the driving elements and the cleaning tools with the Bringing rotor into contact is one Positioning device required that the entire Cleaning device moves axially to the spinning rotor. This Positioning device should have a control device which enables exact positioning.
  • Cleaning tool relative to the rotary drive axially is displaceable so that contact pressure of the driving elements and Immersion depth of the cleaning tool in the rotor opening can be controlled separately.
  • the spinning rotor is additionally during its Drive for cleaning the rotor from an axial Force component freed because the axial contact pressure is not is necessary if the spinning rotor between the Driving elements is pinched.
  • Figure 1 is a spinning rotor 1 with associated Rotor drive unit 4 shown, the spinning rotor 1 has a rotor shaft 1 ', the storage of the Spinning rotor is used.
  • Such storage can be a known support disc bearing, a magnetic bearing or a Act air bearings.
  • the rotor drive unit 4 is advantageous on a movable along a rotor spinning machine Maintenance facility arranged.
  • a double arrow 6 ' indicates that the entire Rotor drive unit 4 slidable along the rotor axis is arranged.
  • This double arrow 6 ' also symbolizes at the same time a positioning device, which by means of a an exact control device, also not shown Positioning of the rotor drive unit 4 enables.
  • a shifting device for example a stepper motor, which is on a threaded spindle or acts on a rack via a worm gear.
  • the drive housing of the rotor drive unit 4 referred to which carries the stator 11 with stator winding 12.
  • the stator 11 or the stator winding 12 corresponds to a rotor magnet arrangement 10 which is based on an electric rotor 9 of the total as an external rotor motor trained rotor drive unit 4 is attached.
  • the Electric rotor 9 is on bearing 13 on a central part of the Drive housing 5 mounted.
  • Rotor 9 On the part of the electrical facing the spinning rotor 1 Rotor 9 is a cup-shaped holder 8 attached, the one annular elastic driving element 7 carries.
  • a cleaning element in the form of a scraper 14 is around one Scraper axis 15 swiveling.
  • the swivel drive is by means of a stepper motor 16 causes.
  • This stepper motor 16 must be the feed movement of the entire rotor drive unit 4 be coordinated in the present example so that the Scraper 14 first pass through rotor opening 3 without any problems can, but is then swung outward quickly enough to close the rotor groove 2 as far as possible without touching the rotor base to reach.
  • the scraper axis 15 within of the drive housing 5 is axially displaceable to the Adjustment of the scraper 14 regardless of the position of the To make rotor drive unit 4.
  • the stepping motor 16 could additionally advance movement can be used if, for example, with a snail in engage a toothing within the drive housing 5 would. He would then use himself as well as the scraper axis 15 Shift scraper 14 axially. For this, however, are also any other linear drives possible.
  • FIG. 2 shows the ring-shaped holder 8 in Sectional view.
  • the variant of the invention shown in FIGS. 3 and 4 differs from the first variant in that the spinning rotor 1 is not provided with a rotor shaft, but is coupled with an electric rotor 1 ′′, which is part of a magnetic / gas bearing is, as is known for example from DE 42 07 673 C1. With such a bearing, it is particularly important that no greater radial forces occur when driving the spinning rotor during the cleaning process, since the magnetic centering of the electric rotor 1 ′′ only withstands limited radial forces. Furthermore, the pot-shaped holder 8 according to the first exemplary embodiment is replaced here by four holders 18 'to 18'''''which are evenly divided on a circular arc.
  • FIGS Another variant of the invention is shown in FIGS shown, in which the driving elements 19 'to 19' '' ' pivotable holders 20 'to 20' '' 'are arranged.
  • the Brackets 20 'to 20' '''are about pivot axes 22' to 22 '' '' can be pivoted by means of solenoids 23 'to 23' '' '.
  • solenoids 23 'to 23' '' 'become push rods 24' to 24 '' '' actuated. These push rods engage in elongated holes 21 'to 21 ''''' in the holders 20 'to 20' '' '.
  • the power supply of the solenoids 23 'to 23' '' ' is only here indicated and can not, for example, by one here shown sliding contact on the drive housing 5th be guaranteed. There is also an inductive coupling conceivable. A special variant of the power supply is but not the subject of the present invention.
  • the eccentric 28 is shown in FIGS. 7 and 8 each out of engagement with the brackets 20 'to 20' '' ' or the reinforcements 27 'to 27' '' '. Thereby are the driving elements 19 'to 19' '' 'on the rotor 1.
  • the Eccentric disc 28 can by means of an electromagnet 32, the is fixed on the electric rotor 9, clockwise be pivoted. This pivoting clockwise causes the portions of the eccentric 28 with larger radius in contact with the holders 20 'to 20' '' ' occur and, as described, a lifting of the driving elements 19 'to 19' ''' 'from spinning rotor 1. There is a pestle for this 32 'of the electromagnet 32 to one on the eccentric disk 28 attached pin 33 articulated.
  • an adjusting screw 34 is the basic position of the plunger 32 ′ in the electromagnet 32 adjustable. In this way, the pivoting path of the holder 20 'to 20' '' 'can be adjusted. So it can also be achieved that the eccentric disc 28 is still in during the drive Contact with the holders 20 'to 20' '' 'remains, which does not the full force of the springs 29 'to 29' '' 'on the holder 20' up to 20 '' ''.
  • a tension spring 35 is also attached to the pin 33, the other end on another pin 36 is attached. This pin 36 is in turn on the electric rotor 9 attached. The tension spring 35 pulls the Tappet 32 'after switching off the electromagnet 32 in the position shown in Figures 7 and 8.
