Definitions

  • the present invention relates to a cleaning device for cleaning a rotor plate of a spinning rotor.
  • the cleaning device has a cleaning head, which has at least one cleaning element for cleaning the spinning rotor, and a receptacle in which the cleaning head is mounted and which can be advanced to the spinning rotor for cleaning.
  • the cleaning head has at least one bearing area, the longitudinal direction of which defines an axial direction of the cleaning head.
  • the DE 37 15 934 A1 describes a cleaning device which has a cleaning head with an extendable scraper as a cleaning element.
  • the cleaning head is arranged on a movably mounted arm so that it can be fed to the spinning rotor. After the cleaning head has been brought to the spinning rotor, the scraper is then extended by means of a piston that can be acted upon by compressed air so that it can reach the rotor groove.
  • a cleaning device in which a blow head is provided in a cleaning head as the cleaning element. After the cleaning device has been fed to the spinning rotor, the blow head is extended by means of a piston and thereby positioned in relation to the rotor groove. After cleaning, the blow head is reset by means of spring force.
  • the EP 1 201 800 A1 a cleaning head which can be fed to a spinning rotor and on which a scraper is arranged such that it can be extended.
  • the scraper can be arranged axially displaceably on the cleaning head.
  • a stepper motor or another linear drive can be used to the Moving the scraper.
  • a cleaning device which has a cleaning head with a scraper as a cleaning element.
  • the cleaning head can be advanced to the spinning rotor by means of a feed unit, so that the cleaning element can get into the interior of the spinning rotor and can clean it on its inside. Since, in particular, the rotor groove of the spinning rotor requires intensive cleaning, it is always essential in such cleaning devices that they are positioned comparatively precisely in relation to the rotor groove during cleaning.
  • the cleaning head of the DE 103 14 936 A1 therefore has a stop element, by means of which the cleaning head makes contact with the spinning rotor during feed and is thereby positioned in the axial direction with respect to the spinning rotor. However, for various reasons, the cleaning head may be incorrectly positioned in relation to the spinning rotor.
  • the object of the present invention is therefore to propose a cleaning device which enables the cleaning device to be precisely positioned in relation to the spinning rotor in a simple manner.
  • the proposed cleaning device for cleaning a rotor plate of a spinning rotor has a cleaning head which has at least one cleaning element for cleaning the spinning rotor, and a receptacle in which the cleaning head is mounted and which can be delivered to the spinning rotor for cleaning.
  • the feed of the receptacle to the spinning rotor can take place by means of a feed unit which, for example, has a pneumatic cylinder, a linear drive or some other drive may have.
  • the cleaning head has at least one bearing area, in particular a cylindrical bearing area, the longitudinal direction of which defines an axial direction of the cleaning head.
  • the longitudinal direction of the storage area is understood to mean the direction of the greatest longitudinal extent of the storage area.
  • the longitudinal direction is understood to mean the direction of a longitudinal axis of the cylinder.
  • the cylindrical area can be designed as a circular cylinder or, in the sense of a mathematical definition of the term “cylinder”, be based on any other base area that was extruded along a guide curve.
  • the direction of the guide curve thus defines the longitudinal axis of the cylinder.
  • a floating bearing is understood to mean a bearing in which the cleaning head is freely movable in both axial directions and is therefore not fixed in the axial direction and also not acted upon in any other way, for example by spring force.
  • the cleaning head As a result of this freely floating mounting, it is now possible for the cleaning head to automatically and automatically adjust itself correctly in the axial direction with respect to the spinning rotor when the cleaning device is fed to the spinning rotor. In particular, this makes it possible to align the cleaning element exactly with respect to the rotor groove. Due to the free mobility in both axial directions, correct alignment or fine adjustment of the cleaning element or the cleaning head is possible both when the cleaning device or the receptacle is fed too close to the spinning rotor by means of the feed unit, and when the feed unit the Cleaning device positioned too far from the spinning rotor.
  • a play of the cleaning head in the axial direction is at least 2 mm, preferably at least 3 mm and particularly preferably at least 4 mm. It has been shown that play of this order of magnitude is sufficient to compensate for any inaccurate positioning of the receptacle by the feed unit or to achieve fine adjustment of the cleaning head by means of the free axial mobility.
  • the at least one cleaning element is a scraper, which can be extended, in particular pivoted about a scraper axis, and is mounted on the cleaning head.
  • the scraper can be extended, for example, by applying compressed air via a piston.
  • the cleaning head has an air supply and the at least one cleaning element can be actuated by means of compressed air.
  • the air duct or the compressed air for actuating the cleaning element can advantageously also serve to move the cleaning head relative to the receptacle.
  • the cleaning head By extending the at least one scraper, the cleaning head can be positioned in the axial direction in relation to a rotor groove of the spinning rotor to be cleaned.
  • the scraper first hits a certain point on the rotor base or the rotor slide wall due to the infeed by the infeed unit and slides by itself due to the incline of the rotor base or the rotor slide wall and due to the increasing diameter in the direction of the rotor groove during the further extension into the rotor groove.
  • the cleaning head has an air supply and the at least one cleaning element can be actuated by means of compressed air.
  • the at least one cleaning element is a blow hole to which compressed air can be applied via the air supply to the cleaning head.
  • both a scraper or some other mechanical cleaning element and a blow hole, possibly also several blow holes, are arranged on the cleaning head.
  • the cleaning head by applying compressed air to the blow hole, the cleaning head can be positioned in the axial direction with respect to the spinning rotor to be cleaned, in particular with respect to a rotor groove of the spinning rotor.
  • the cleaning head has a stop by means of which it can be positioned in the axial direction with respect to the spinning rotor to be cleaned, in particular with respect to a rotor groove of the spinning rotor to be cleaned.
  • a very precise alignment of the cleaning head with respect to the spinning rotor can thus also be achieved in this case.
  • the receptacle has an air chamber which is connected to the air supply through at least one overflow opening. Compressed air can be applied to the air chamber via the overflow opening, thereby moving the cleaning head in the axial direction.
  • the air chamber has an exhaust air opening to which a shut-off valve is preferably assigned.
  • the cleaning head can thus optionally be moved by means of compressed air be made possible or prevented.
  • preventing a movement of the cleaning head can be advantageous if a further cleaning element is to be used, which is positioned in a different way with respect to the spinning rotor or is delivered to it.
  • the further cleaning element can also be arranged on the cleaning head.
  • a lockable exhaust air opening can also be advantageous in order to be able to equip the cleaning device with different types of cleaning heads.
  • the cleaning head can have both one or more scrapers and one or more blower nozzles as cleaning elements.
  • Figure 1 shows a cleaning device 1 for cleaning a rotor disk 2, a spinning rotor 3.
  • the spinning rotor 3 has a rotor shaft 13 to which the rotor disk 2 is fixedly or detachably attached.
  • the soiling can vary depending on the fiber material used or the degree of cleaning of the fiber material and can also contain strong buildup on the inside of the spinning rotor 3.
  • the rotor groove 8 is subject to considerable contamination, which has a disadvantageous effect on the further spinning process.
  • the spinning rotors 3 must therefore be cleaned regularly, especially in the area of the rotor groove 8, for which the cleaning device 1 is provided.
  • the cleaning device 1 contains a receptacle 6 which can be fed to the spinning rotor 3 by means of a feed unit 9, which is only indicated here, and on which a cleaning head 4 for cleaning the spinning rotor 3 is arranged.
  • the cleaning device 1 can be arranged, for example, by means of the feed unit 9 on a maintenance device that can be moved along spinning positions of an open-end rotor spinning machine, wherein the feed unit 9 can contain a pneumatic cylinder, an electric linear drive or some other drive in order to accommodate the cleaning head 4 with the spinning rotor 3 to send.
  • the maintenance device like the open-end rotor spinning device, is not shown.
  • the receptacle of the present cleaning device surrounds the spinning rotor 3 in the shape of a pot and can contain a rotary drive by means of which the spinning rotor 3 can be driven during its cleaning.
  • the spinning rotor 3 it is likewise also possible for the spinning rotor 3 to be attached to the open-end rotor spinning device by means of one arranged drive is set in rotation.
  • the present cleaning head 4 has two scrapers 5 a as cleaning elements 5, which are mounted on the cleaning head 4 so as to be pivotable about a scraper axis SA.
  • the swiveling out of the scrapers 5a which can be actuated by means of a piston 14, for example, is indicated by a dot-dash line.
  • the piston 14 is moved to the right, as indicated by the arrow.
  • the piston 14 can be actuated pneumatically, for which the cleaning head 4 has an air supply 10 (see Fig. Figures 4-6 ) and can be pressurized with compressed air.
  • the extension of the scrapers 5a can also take place by means of a motor or in some other way.
  • the cleaning head 4 has at least one bearing area 7, which in the present case is cylindrical due to its outer diameter on the area facing the receptacle 6 and which defines an axial direction AR of the cleaning head 4 via its longitudinal axis, here the central longitudinal axis.
  • the cleaning head 4 can of course also have further or other cylindrical areas or bearing areas 7 which define the axial direction AR.
  • the cleaning head 4 is now floatingly mounted in the axial direction AR on the receptacle 6 and has axial play.
  • the cleaning head 4 is shown in a central position in which it has play in both axial directions AR with respect to the receptacle 6, as shown by the two distances x.
  • the cleaning head 4 itself to be mounted firmly, ie without play, on the receptacle 6 and for a distance x to be provided between the scraper or scrapers 5a and the cleaning head 4 .
  • Figure 2 shows the cleaning device 1 of FIG Figure 1 in a second position in which the cleaning head 4 has already been fed to the spinning rotor 3 by means of the receptacle 6 and the feed unit 9.
  • the problem often arises that, due to setting errors of the cleaning device 1 in relation to the delivery unit 9 or the movable maintenance device, due to positional deviations of the maintenance device in relation to the spinning station, due to play between the various components or due to other causes, the positioning of the cleaning device 1 cannot take place exactly in the axial direction with respect to the spinning rotor 3, so that the cleaning elements 5 often cannot reach the rotor groove 8 exactly. Reliable cleaning of the rotor groove 8 is then no longer possible.
  • the cleaning device 1 is positioned too far away from the spinning rotor 3 in the axial direction AR, for example.
  • the scrapers 5 a When the scrapers 5 a are extended, they therefore do not get into the rotor groove 8, but lie against the rotor slide wall 17 of the rotor disk 2.
  • the cleaning head 4 due to the further loading of the piston 14 or some other actuating element, for example a motor, and the increasing diameter in the direction of the rotor groove 8, the cleaning head 4 is now moved in the axial direction AR with respect to the receptacle 6, removing at least part of the axial play ( see arrows).
  • FIG 3 Another situation of the cleaning device 1 is shown, in which the cleaning device 1 has already been delivered to the spinning rotor 3 and the cleaning head 4 has already automatically positioned itself correctly in relation to the rotor groove 8.
  • the cleaning device 1 has been positioned too close to the spinning rotor 3, so that the scrapers 5a initially hit the rotor base 18 of the spinning rotor 3. Due to the further loading of the piston 14 or the actuating element of the scrapers 5a, the scrapers 5a slid along the incline of the rotor base 18 in the direction of the larger diameter of the rotor groove 8, with the play between the cleaning head 4 and the feed unit 6 on the one hand Side of the cleaning head 4 was at least partially canceled.
  • the cleaning head 4 is shown in its completely retracted position with respect to the receptacle 6, so that there is now a distance 2x between the cleaning head 4 and the receptacle 6 in the left-hand area of the figure.
  • the cleaning head 4 does not have to be displaced by the complete distance x or 2x, but various intermediate positions are also possible depending on the distance between the cleaning head 4 and the spinning rotor 3 after the infeed.
  • Figure 4 shows another embodiment of a cleaning device 1, in which the cleaning element 5 is not formed by a scraper 5a, but by a blow hole 5b.
  • the cleaning head 4 here has an air duct 10, via which compressed air can be supplied to the cleaning head 4 is. By means of the compressed air supplied via the air supply 10, the blow hole 5b is in turn acted upon with compressed air. Two blow holes 5b lying opposite one another are shown here.
  • the cleaning head 4 is positioned in the axial direction AR in relation to the spinning rotor 3 by the application of compressed air to the blow hole 5b. This takes place in that the cleaning device 1 or the receptacle 6 of the cleaning device 1 has an air chamber 12 which is connected to the air supply 10 via at least one overflow opening 15.
  • the overflow opening 15 is only formed by an annular gap existing between the housing 9 and the cleaning head 4, as symbolized by a small, curved arrow.
  • a defined overflow opening 15 can also be provided between the cleaning head 4 and the air chamber 12. If compressed air now reaches the air chamber 12 via the overflow opening 15, this results in the entire cleaning head 4 with the blow hole or bores 5b being displaced in the axial direction AR of the cleaning head 4, as symbolized here by the two small arrows near the cleaning head 4 .
  • the position of the cleaning head 4 relative to the spinning rotor 3 can be adjusted in this way.
  • the cleaning head 4 has a stop 11 for this purpose, which interacts with a corresponding stop of the receptacle 6.
  • the cleaning head 4 with the blow hole 5b can hereby be brought very close to the rotor groove 8 and thereby positioned opposite it. Since cleaning by means of a blow hole 5b does not require the cleaning element 5 to be aligned with respect to the rotor groove 8 as precisely as cleaning by means of a scraper 5a, the maximum possible extension of the cleaning head 4 out of the receptacle 6 already results in a good alignment of the blow hole 5b in relation take place on the spinning rotor 3. Alternatively or additionally, however, a stop 11 could also be provided which contacts the spinning rotor 3 and thereby enables an even more precise positioning relative to it, as in FIG Figures 5 and 6 shown.
  • Figure 5 shows a further embodiment of a cleaning device 1, which as cleaning element 5 has both two scrapers 5a and a blow hole 5b.
  • Compressed air can be fed to the cleaning head 4 via the air feed 10 and the piston 14 can be displaced, which in turn actuates the scraper 5a.
  • the game of the cleaning head 4 and the distances x are in the Figures 5 and 6 not labeled for the sake of clarity.
  • the air chamber 12 is assigned an exhaust air opening 16. If, when the piston 14 is pressurized or when the scraper 5a is actuated with compressed air, which is supplied via the air supply 10, compressed air reaches the air chamber 12 via the overflow opening 15, this can easily escape via the exhaust air opening 16.
  • the cleaning head 4 is thus, as in FIGS Figures 1 to 3 shown, floating in or on the receptacle 6, so that an automatic adjustment of the cleaning head 4 is possible in the axial direction and the rotor groove 8 can be cleaned by means of the scraper 5a.
  • the exhaust air opening 16 can be closed by means of a shut-off valve, not shown here, as in FIG Figure 6 symbolized by a line in the area of the exhaust air opening 16.
  • a stop 11 is arranged on the cleaning head 4 which contacts the spinning rotor 3 during axial displacement, so that the cleaning head 4 is automatically correctly positioned in relation to the spinning rotor 3, in particular in relation to the rotor groove 8 of the spinning rotor 3.
  • the stop 11 makes contact with the rotor base 18 of the spinning rotor 3.
  • the embodiment shown with a lockable exhaust air opening 16 is that the cleaning head 4 as in the Figures 1-3 shown can be stored floating freely within the receptacle 6 in order to position the scraper 5a automatically, and after the exhaust air opening 16 has been shut off, the air chamber 12 can be acted upon, which actively pushes the cleaning head out of the receptacle 6.
  • the one in the Figures 5 and 6 The cleaning head 4 shown or the cleaning device 1 can therefore be used in a particularly flexible manner. It is also conceivable, in the case of a cleaning device 1 with such a lockable air chamber 12, to design the cleaning head 4 in two or more parts, as is also shown in FIG Figures 5 and 6 is shown. Different cleaning elements 5 can thus be arranged interchangeably on the cleaning device 1 in a simple manner. Of course, such a two-part design of the cleaning head 4 could also be used in the cleaning devices 1 of the Figures 1 to 4 can be used advantageously.
