Definitions

  • the present invention relates to an open-end rotor spinning machine with a large number of spinning positions located next to one another, each with a spinning rotor, which is arranged in a housing located in a machine-side receptacle and has a drive axis extending transversely to the machine longitudinal direction, by means of which it drives from a drive belt extending in the machine longitudinal direction is driven, the drive axle being mounted in the gusset of a support disk bearing.
  • a device of this type is known from DE-OS 2,515,783.
  • the spinning rotor rotates at high speeds, so that its bearing is subject to relatively high wear and must therefore be replaced from time to time. This wear occurs more often when there is an imbalance in the spinning rotor.
  • the housing accommodating the spinning rotor is removed in order to make the support disk bearing accessible and then also to be able to remove it.
  • the support disc bearing When removing and installing the support disc bearing, there is a risk that the support discs will still turn or come to rest against the drive belt and be driven positively. This harbors a risk of injury for the operator, so that the entire machine must always be shut down for safety reasons for the individual removal and installation of a housing.
  • the present invention is therefore based on the object of avoiding these disadvantages in a generic open-end spinning machine and of creating a simple device in which the rotor bearing can be exchanged safely while the machine is running.
  • the support disc bearing is supported by the housing receiving the spinning rotor, which is mounted on a pivot axis and can be pivoted away from the drive belt at least to such an extent that the housing can be removed from the machine-side receptacle.
  • the support disk bearing is lowered so far under the drive belt or raised above the drive belt that the support disks come free from the drive belt and can be removed from the receptacle under the drive belt or over the drive belt. This can be done by a rectilinear or curved movement of the housing with the support disk bearing attached to it or also by continuing the initially initiated pivoting movement, which can be released from the receptacle by releasing a lock or screw connection, etc.
  • the drive axles with the A drive shaft or housing that accommodates both the opening and the spinning elements can be swiveled out of its machine-side receptacle as a whole about the pivot axis. According to the invention, this can also be carried out in such a way that the second housing is connected to the rotor housing and can be pivoted together with the latter.
  • the machine parts which are stationary with respect to the pivotable housing and the parts attached to it and which are located in the pivoting range of the pivotable parts, have a minimum distance from the pivot axis which is greater than the maximum distance of the parts to be pivoted past these machine parts. In this way it is ensured that the housing with all the parts carried by it can be pivoted freely from the machine frame by drive means, brakes, etc., so that the drive axle and the support disk bearing can be checked by eye.
  • the pivoting movement of the housing separates the drive axle from its drive belt and removes it so far that during the subsequent expansion, it is also inadvertently impossible to temporarily drive the rotatably mounted elements in the housing.
  • the control of the elements attached to the housing can thus be carried out without the operator being at risk even when the machine is running.
  • both the complete housing accommodating the spinning rotor and parts thereof can be removed or installed or exchanged, so that the other spinning positions can continue to operate undisturbed.
  • the maximum distance of a drive axis of the opening element from the pivot axis is at least as large as the minimum distance of the drive means of the delivery element from the pivot axis and that The maximum distance of this drive axis from an imaginary vertical plane located between the swivel axis and the drive means is smaller than the minimum distance of this drive means from this plane.
  • the housing can be pivoted for the purpose of inspection, maintenance or replacement without any risk to the operator.
  • the drive means of at least one of the rotating elements are arranged in a channel-like covering which extends over a plurality of spinning stations located next to one another and which carries the pivot axes of the housings of these spinning stations and one longitudinal side of which is covered by these housings.
  • This channel enables a compact and low-noise design of the device according to the invention.
  • the channel-like covering preferably ends on its side facing away from the pivot axis at a minimum distance that is greater than the maximum distance of the drive axis and / or the support disk bearing from the pivot axis.
  • the term “bearing” also includes possibly lubrication devices for such a bearing.
  • the subject invention can also be combined with a Sc h mutzabscheidevoriques shall apply.
  • the invention provides that the housing, which is mounted with its upper end receiving the spinning element on the pivot axis, on its underside has a dirt separating opening leading away from the opening element with guide walls extending parallel to the pivot axis, the maximum distance and the maximum distance of the drive axis of the delivery or opening elements from the pivot axis are at least as large, and that below the housing a dirt removal belt in an open top Guide channel is guided, the side walls extend in the direction of the guide walls and the minimum distance from the pivot axis is greater than the maximum distance of the side walls from the pivot axis.
  • the side walls of the guide channel do not hinder pivoting movements of the housing in this way, but nevertheless reach up to the immediate vicinity of the guide walls of the dirt separating opening. As a result, the separated dirt arrives safely on the dirt removal belt without the risk of the spinning machine flying away.
  • the guide channel is fastened to the channel-like envelopes which carry the housings of a plurality of spinning stations located next to one another.
  • the drives have axes of the delivery element and the opening element designed as an opening roller relative to the drive axis of the spinning rotor have such an inclination and the opening roller is arranged relative to the spinning rotor in such a way that the fiber feed channel leading from the opening roller to the spinning rotor is arranged and formed symmetrically to the central radial plane through the opening roller is.
  • a housing accommodating a spinning rotor with a pivotable cover and to provide a stationary brake linkage which can be brought into its braking position by pivoting the cover.
  • the brake linkage preferably has one regardless of the position of the cover actuatable control arm. In this way, a spinning station for cleaning the spinning rotor and / or for piecing manually or automatically, e.g. B. be controlled from a piecing car with the cover closed.
  • a lock is provided to secure the housing in its operating position and is only accessible after the cover has been pivoted away.
  • a locking device securing the housing in its maintenance position is advantageously provided in a further embodiment of the subject matter of the invention.
  • a valve that can be controlled as a function of the pivoting position of the housing can also be provided in the vacuum line to the housing. In this way it is inevitably ensured that no vacuum loss can occur at this spinning point when the housing is pivoted or removed.
  • the present invention enables the driven elements of each spinning station to be checked in a simple and safe manner without the entire spinning machine having to be shut down in order to maintain the safety of the operator.
  • This safety for the operator is also given when installing or removing a housing. With this simplicity of construction and with this safety for the operator, there is a higher production during this inspection and maintenance phase, since the neighboring spinning stations can continue to operate normally without impairing the spinning station to be checked or serviced.
  • each spinning station has an individual housing 1 which is pivotally mounted on a pivot axis 10 at its upper end.
  • the pivot axis 10 is mounted in a holder 12 carried by the machine frame 11 and extends in the machine longitudinal direction.
  • the housing 1 accommodates a delivery device 2, an opening device 3 and a spinning rotor 40.
  • a delivery device 2 Of the delivery device 2, only one delivery element designed as a delivery roller 20 is shown in FIG. 1, while the opening device 3 shown has an opening element designed as an opening roller 30.
  • a fiber feed channel 31 extends from the opening roller 30 into the interior of the spinning rotor 40.
  • a thread take-off tube 41 carried by a cover 5 leads out of the housing from the interior of the spinning rotor 40.
  • the delivery roller 20 is driven by a drive shaft 21, which extends in the machine longitudinal direction via a plurality of spinning positions located next to one another, that per spinning place a worm wheel 22 with which a worm wheel 23 is engaged.
  • This worm wheel 23 is located on the end of a drive shaft 24, on the other end of which the delivery roller 20 is mounted.
  • the opening roller 30 is located on the end of a drive shaft 32, the other end of which rests against a drive belt 33 in its operating position.
  • the spinning rotor 40 is also carried by a drive axle 42, the free end of which rests against a drive belt 43 in its operating position.
  • the spinning rotor 40 is mounted in the gusset of a support disk bearing 44 which, according to the exemplary embodiment shown in FIG. 1, has two pairs of support disks 440 and 441.
  • the support disk bearing 44 is attached to the rear of the housing 1 and can therefore be pivoted together with the latter.
  • the spinning machine operates in a conventional manner.
  • a sliver (not shown) is fed to the opening roller 30 with the aid of the delivery device 2, broken up by the latter into individual fibers and fed in this form through the fiber feed channel 31 to the collecting groove of the spinning rotor 40 and deposited there in the form of a fiber ring.
  • a thread generated in the spinning rotor 40 is withdrawn from the spinning rotor 40 through the thread draw-off tube 41 with continuous integration of the fiber ring and wound up on a spool (not shown).
  • the drive axles 24, 32 and 42 extend transversely to the longitudinal direction of the machine and lie against their drive means (worm wheel 22, drive belt 33 and drive belt 43) at different distances from the swivel axis 10.
  • the housing 1 is fixed in its spinning position in a manner not shown, for example with the aid of screws. If the support disc bearing is now to be made accessible for maintenance, replacement, etc., the fixing of the housing 1 is released and this housing 1 is pivoted in the direction of the arrow P 1 .
  • the drive axle 42 is detached from the drive belt 43.
  • the drive axle 32 is removed from the drive belt 33 and the worm wheel 23 from the worm wheel 22.

  • the support disk bearing 44 is pulled under the drive belt 43. Now the support disc bearing 44 can be supplied with new oil or serviced in some other way. Maintenance of the delivery roller 20 and the opening roller 30 and their bearings is also possible. The neighboring spinning positions are in no way affected by this removal and a later reinstallation of the housing 1 and continue to run undisturbed.
  • the cover 5 of the housing 1 is closed during installation and removal. The operator thus comes into contact with all the elements mounted on and in it and with none of the drive means during the installation and removal of the housing 1, and is therefore at no time endangered by these elements or by the elements driven by them.
  • Fig. 1 shows an embodiment of the device described, in which the support disc bearing 44 can be made accessible only by swiveling out of the machine, wherein the housing 1 can then also be removed from the machine if necessary.
  • the maximum distance A of the drive axis 42 of the spinning rotor 40 and its support disk bearing 44 closest to the pivot axis 10 is smaller than the minimum distance of the drive means not assigned to the spinning rotor 40 from the pivot axis 10, namely as the minimum distance B of the drive belt 33 and the minimum distance C of the drive shaft 21 from this pivot axis 10.
  • the maximum distance D of the drive axis 32 of the opening roller 30 from the pivot axis 10 is greater than the minimum distance C of the worm wheel 22 on the drive shaft 21 thereof.

  • the maximum distance E of the drive axis 32 from an imaginary vertical plane V between the pivot axis 10 and the drive means (worm wheel 22, drive belt 33 and 43) is smaller than the minimum distance F of the worm wheel 22 from this imaginary plane V.
  • the housing 1 with the rotatable elements mounted therein (delivery device 2, opening device 3 and spinning element 4) can be pivoted out of the machine about the pivot axis 10 without the drive means (worm wheel 22 and drive belt 33 and 43) are a hindrance here.
  • the support disk bearing 44 is accessible.
  • Such an element can e.g. be a brake that works with one of the driven elements.
  • This can also be a support roller 61 or 63 (FIG. 3) for one of the drive belts 43 or 33.
  • the arrangement of the rotatable elements (spinning rotor 40, opening device 3 and delivery device 2) in the housing 1 is unchanged from that according to FIG. 1, but the housing is supported at its lower end on the pivot axis 10 .
  • the pivot axis 10 is thus located at the end of the housing 1 facing away from the spinning rotor 40.
  • the maximum distance G of the worm wheel 23 on the drive axis 24 arranged closest to the pivot axis 10 is smaller than the minimum distances H and K of the pivot axis 10 Drive belts 33 and 43 not assigned to this drive axle 24.

  • Fig. 3 shows an embodiment of the device shown schematically in Fig. 1. Care is taken to ensure that the maximum distance A of the support disk bearing 44 fastened to the housing 1 for the drive axis 42 of the spinning rotor 40 from the pivot axis 10 is smaller than the minimum distance B of the drive means for the opening device 3 and the delivery device 2 (FIG. 1).
  • the drive means (drive belt 43) are arranged in a channel-like covering 6, which extends over a large number of spinning stations located next to one another.
  • the casing 6 carries between the drive axes 42 of the spinning rotors 40 of adjacent spinning stations a holder 60 for support rollers 61 for the drive belt 43.

  • the channel side 62 is designed as a holder for support rollers 63 for the drive belt 33 of the opening roller 30.
  • These support rollers 63 are located between the drive axles 32 of adjacent spinning positions and are therefore generally outside the swivel range of the drive axle 42 and the support disk bearing 44 for the spinning rotor 40. Otherwise, it must be provided that the minimum distance B (FIG. 1) of these support rollers 63 as well that of the drive belt 33 is greater than the maximum distance A of the drive axle 42 and the support disk bearing 44.
  • the fiber feed channel 31 is formed symmetrically to the central radial plane R through the opening roller.
  • the drive axles 24 and 32 of the delivery device 2 and the opening are provided direction 3 correspondingly inclined relative to the drive axis 42 of the spinning element 4.

  • the drive axles 24 and 32 are relatively far away from the drive axle 42 with its bearing 44, which considerably simplifies the inspection and maintenance of these parts.
  • Fig. 4 shows a further modification of the device described.
  • the housing 1, which accommodates both the spinning rotor 40 and the delivery device 2 and the opening device 3, as in the embodiments shown in FIGS. 1 to 3, has on its underside a dirt separating opening 7 leading away from the opening roller 30, which is divided into two Longitudinal machine direction extending guide walls 70 and 71 is shielded.

In this guide channel 72, the two strands of a dirt removal belt 75 are guided.
  • the guide channel 72 is delimited by two side walls 73 and 74 which extend in the longitudinal direction of the machine and which extend in the vicinity of the guide walls 70 and 71.
  • the minimum distance N of these side walls 73 and 74 from the pivot axis 10 is, however, slightly larger than the maximum distance M of the guide walls 70 and 71 and the worm wheel 23 on the drive axis 24 from this pivot axis 10 This way, it is ensured during production that the dirt excreted on the opening roller 30 is guided safely onto the dirt removal belt 75, but that, on the other hand, pivoting of the housing 1 with the support disk bearing 44 is not impaired for control, maintenance or replacement purposes.

  • a second drive belt 45 is therefore provided parallel to the drive belt 43, which is driven at a lower speed than the drive belt 43 and can be brought into contact with the drive axis 42 of the spinning rotor 40 by means of a roller 93.
  • the roller lever 9 in the embodiment shown is designed as a balance lever which carries the roller 91 on its one arm 900 and the brake lever 83 and the roller 93 on its other arm 901.
  • the pivot axis 90 of the roller lever 90 is arranged stationary in the machine with the aid of a bearing 94. So that the pivotability of the housing 1 is not impaired, the roller lever 9 and the brake lever 83 are located on the same side of the drive axis 42 of the spinning rotor 40 as the drive belts 43 and 45.
  • the roller 91 can be lifted off the drive belt 43 and the roller 93 for resting on the drive belt 45 by exerting pressure on the control arm 833 for piecing to be brought.
  • the drive belt 43 releases the drive axis 42 of the spinning rotor 40, while the drive belt 45 bears against this drive axis 42 and thus drives the spinning rotor 45 at a reduced speed.
  • the described embodiments show that by pivoting the housing 1 with the support disk bearing 44 flanged to it, the support disks 440 and 441 can be removed as far up or down from the drive belt 43 or from the drive belts 43 and 45 that the support disks 440 and 441 at one Removing the housing 1 with the drive belts 43 or with the drive belts 43 and 45 no longer come into contact. It doesn't matter whether the case 1 after detaching from the pivot axis 10 is only pulled out to the front (arrow P 2 ) or whether the pivoting movement of the housing 1 is continued (arrow P 1 ) until the support disk bearing 44 is accessible from the pivot axis 10 even without detaching the housing 1. Also, the special design of the support disk bearing 44, for example with one or two pairs of support disks, is not of crucial importance for the device described.
  • the support disk bearing 44 is attached, as shown in the figures, to a housing 1 which receives both the spinning rotor 40 and the delivery device 2 and the opening device 3. 7 and 8 show, separate housings 45 and 34 can also be provided, of which the first housing 45 accommodates the spinning rotor 40 and the second housing 34 the delivery device 2 and the opening device 3. These housings 45 and 34 can be rigid with one another be connected so that all driving and driven elements of a spinning station are accessible through their joint pivoting.
  • the two housings 45 and 34 are mounted independently of one another.
  • the (rotor) housing 45 is pivotally mounted on a pivot axis 10, while the housing 34 is pivotably mounted on the drive shaft 21 for the delivery roller 20 by means of a holder 35 (FIG. 7).
  • the housing 34 and the cover 5 are held in contact with the rotor housing 45 by elastic means, not shown.
  • the rotor housing 45 is again pivoted out of the machine.
  • the housing 34 with all the in and on facilities stored in it (delivery device 2, opening device 3, cover 5) are lowered so far that the rotor housing 45 can be pivoted forward.
  • all driving and driven elements of a spinning station can be checked without endangering the operator, and depending on the intended pivoting range of the housings 45 and 34 and the element to be checked, there is even no need to remove the housings 45 and / or 34 can.
