Definitions

  • the present invention relates to a work station of a rotor spinning machine with a spinning rotor rotatably mounted about an axis of rotation, the work station comprising a cleaning unit with a mechanical cleaning element for cleaning an inner surface of the spinning rotor.
  • a method for cleaning an inner surface of a spinning rotor which is mounted on a work station of a rotor spinning machine so as to be rotatable about an axis of rotation, is proposed with the aid of a cleaning unit of the work station, the cleaning unit comprising a mechanical cleaning element.
  • Rotor spinning machines usually consist of a large number of workstations, which are usually arranged side by side. A work process is carried out at each of these individual workplaces. For example, in a first step, a supplied sliver is separated into its individual fibers by a dissolving device. In a further step, the separated fibers are then spun into a yarn in a spinning rotor. A subsequent winding device winds this yarn onto a bobbin in a final operation.
  • the spinning rotor of the work station is a component that is susceptible to contamination due to its design and process. Since it is not yet technically possible to keep the sliver free of any foreign substances and other contaminants, it is necessary to regularly maintain and clean the spinning rotor. For this purpose, a maintenance flap or a locking device is usually available at the work station, through which the spinning rotor is accessible from the outside after it has been opened. This finally allows easy access to the spinning rotor.
  • an automatic cleaning unit is usually attached to the workstation or a service robot of the rotor spinning machine.
  • a textile machine in particular a rotor spinning machine
  • the arrangement of the cleaning device can be arranged both on or in a housing of the work station and on or in a closure device of the same.
  • the cleaning device contains a cleaning element, this cleaning element being able to be moved into a cleaning position by a single drive.
  • the corresponding movement can include a rotary movement about an axis of rotation of the cleaning element.
  • the cleaning element engages with a rotor groove, in particular via a mechanical scraper.
  • Further state of the art can be found in the DE 26 18 094 A1 or the DE 39 11 946 A1 .
  • the object of the present invention is to develop the known prior art.
  • a work station of a rotor spinning machine with a spinning rotor rotatably mounted about an axis of rotation is proposed, the work station comprising a cleaning unit with a mechanical cleaning element for cleaning an inner surface of the spinning rotor.
  • the cleaning element is arranged so as to be movable at the work station such that it starts from a Rest position, in which the cleaning element is not in contact with the spinning rotor, can be moved into different cleaning positions for different inner diameters of the spinning rotor, the cleaning element being in contact with the inner surface of the spinning rotor in the respective cleaning position.
  • the rest position of the cleaning element is arranged outside the spinning rotor, in particular outside a closure device of a housing that houses the spinning rotor.
  • the rest position can be in a separate protective device so that the cleaning element cannot be damaged during normal operation of the work place.
  • the cleaning position lies within the spinning rotor, the exact cleaning position being defined by the diameter of the spinning rotor.
  • the mechanical cleaning element is in contact with an inner wall, in particular with the rotor groove, of the spinning rotor.
  • the cleaning effect of the cleaning unit arises above all from rubbing or scraping the cleaning element on the inner wall of the spinning rotor, the intensity of the rubbing or scraping being determined by the contact pressure of the cleaning element.
  • the cleaning unit is designed as a structural unit, ie as a self-contained module. For maintenance, assembly and replacement as a whole unit, this can be removed from the remaining sections of the workstation in just a few steps, for example by loosening a quick connector or a few screws, or it can be easily assembled accordingly. This reduces the time required for assembly / disassembly and, in the event of an error message, enables the cleaning unit or the work station to have a shorter downtime.
  • the energetic supply of the cleaning unit is carried out by the work place through a contact system or a contactless energy transfer or a comparable energy transfer.
  • Such an interface for energy transmission is preferably arranged at the work site in the area of the rotor cleaning. It is also advantageous if control commands of the control of the rotor spinning machine or of the work station having the cleaning unit can be transmitted to the cleaning unit through this interface.
  • the cleaning unit comprises a first drive which moves the cleaning element between the rest position and the respective cleaning position.
  • the first drive can also take over only part of the movement sequence from the rest position to the cleaning position and a second drive (described in more detail below) can execute a second part of the movement sequence to the cleaning position.
  • the cleaning element preferably comprises a cleaning arm which is connected to the first drive and on whose end remote from the first drive a cleaning scraper or a cleaning brush is arranged.
  • the first drive comprises an electric motor, preferably a stepper motor or a servo motor, the electric motor being designed to pivot the cleaning element about an axis of rotation.
  • the electric motor being designed to pivot the cleaning element about an axis of rotation.
  • the axis of rotation of the cleaning element and the axis of rotation of the spinning rotor run parallel, skewed or obliquely to one another in a common plane. This enables the cleaning element to be simply retracted or pivoted into the spinning rotor, since the upper opening of the spinning rotor is often significantly smaller than its diameter in the region of the rotor groove.
  • a skewed position of the axes of rotation of the cleaning element and the spinning rotor would thus lead, for example, to a multidimensional movement sequence of the tip of the cleaning element to the plane of the spinning rotor. In other words, the skewed position would lead to a movement sequence comparable to that of a corkscrew.
  • the cleaning element is mounted such that the angle of the axis of rotation of the cleaning element with respect to the axis of rotation of the spinning rotor can be changed. This would give a much greater flexibility with regard to the diameter of the spinning rotor to be cleaned. This also makes it easier to insert the cleaning element into the spinning rotor.
  • the drive comprises a linear drive, preferably in the form of a pneumatic cylinder, with the aid of which the cleaning element is preferably white and at least sectionally movable in a linear movement.
  • the pneumatic cylinder is preferably arranged such that the cleaning element can be moved parallel, orthogonal or skewed to the axis of rotation of the spinning rotor.
  • the linear drive can also be arranged such that the cleaning element can be pivoted about a further axis of rotation, so that the angle between the first axis of rotation and the axis of rotation of the spinning rotor can be changed.
  • the drive is assigned an energy store, preferably in the form of a spring, the energy store being arranged in such a way that the cleaning element can be moved from its cleaning position into its rest position or vice versa. It is also advantageous if the energy store is arranged in such a way that it can be used to carry out at least part of the movement sequence of the cleaning element from the cleaning position to the rest position or vice versa. As a result, the drive configuration or the drive of the cleaning unit can be made simpler. It also enables the use of single-acting pneumatic cylinders, i.e. of pneumatic cylinders without reset mechanism or without pneumatic line for a reset mechanism.
  • the cleaning unit is assigned a guide, in particular in the form of a link guide, this guide being designed such that it takes over at least part of the movement sequence of the cleaning element from its rest position into its cleaning position.
  • the guidance is linear, i.e. is designed for a linear movement of the cleaning element.
  • the guide serves to rotate or incline the first drive about an axis of rotation or the cleaning element itself. This would allow a more complex motion sequence in connection with a relatively simple drive concept.
  • the guide comprises at least two guide sections. These guide sections preferably run offset and / or inclined to one another and thus make it possible to move the cleaning element in different directions.
  • the guide sections are preferred and at least in sections formed such that a linear movement and / or rotation and / or inclination of the cleaning element is effected. This makes it possible to further simplify the drive concept without losing flexibility with regard to the different inner diameters of the spinning rotor.
  • this guide includes an adjustment option for limiting and / or changing the movement sequence in one or more directions, this limitation as a stop, as a screw limitation or as an insertion limiter (in other words: component which is inserted into the guide and forms a geometric boundary).
  • This can be designed such that the end position and / or one or more intermediate positions of the cleaning element can be changed.
  • This limitation is preferably designed in such a way that when the cleaning unit is installed at the work station and / or when it is operated, it is externally, i.e. without disassembling the cleaning unit itself. This would increase the flexibility with regard to the end position and the insertion movement of the cleaning element into the spinning rotor, as a result of which a larger number of spinning rotors with different diameters could be covered with the same cleaning unit.
  • the cleaning unit comprises a second drive, this drive being designed in particular as a linear drive or as an electric motor according to the previous description.
  • This is in particular arranged on the first drive in such a way that, in combination with the first drive, the cleaning element can be pivoted about a plurality of axes of rotation, a method in a plurality of directions of movement which are inclined and / or offset relative to one another, or any combination thereof. This makes it possible for the movement sequences to be set even more precisely and in particular automatically by means of a targeted control.
  • the cleaning unit comprises a pneumatic suction and / or blowing unit, which is designed to remove foreign material located on and / or in the spinning rotor.
  • the pneumatic suction and / or blowing unit is preferably arranged in the region of the cleaning element, so that the foreign material detached from the spinning rotor by the cleaning element, in particular fiber residues, can be removed from the inner region of the spinning rotor. This enables an efficient removal of loose foreign material, in particular when the cleaning element is moved in and / or out of the spinning rotor.
  • a method for cleaning an inner surface of a spinning rotor which is rotatably mounted about an axis of rotation at a work station of a rotor spinning machine, is proposed with the aid of a cleaning unit of the work station, the cleaning unit comprising a mechanical cleaning element.
  • the cleaning element is moved from its rest position, which is arranged outside the spinning rotor, in particular outside a closure device of a housing accommodating the spinning rotor, and in which the cleaning element is not in contact with the spinning rotor, into a cleaning position.
  • the cleaning position is selected depending on the spinning rotor currently used in the work place, in particular its inside diameter. In principle, there are several different and different cleaning positions that are used depending on the spinning rotor.
  • the setting of the cleaning position is in particular automatically taken over by the central control of the rotor spinning machine or a control of the respective work station, can be used if necessary and / or Control can also be taken over manually by the operating personnel.
  • the cleaning position is defined by the inside diameter of the spinning rotor and is selected by the control of the spinning machine.
  • the cleaning position is chosen so that the cleaning element in its end position in the spinning rotor is in contact with the rotor groove and / or the side wall of the spinning rotor.
  • the cleaning element is pressed against the surface to be cleaned with a defined force, this force being variable during a cleaning cycle.
  • the first drive which is preferably designed as a stepping motor.
  • the effect of the cleaning element in this case is in principle comparable to that of a jackhammer. This removes contaminants adhering to the inner wall particularly effectively.
  • the control of the rotor spinning machine determines the power consumption of the first and / or second drive and, in the case of rotary drives, the revolutions or steps or, in the case of linear motors, the distance from the starting position to the actual position.
  • This makes it possible to determine the force applied to the cleaning element or the pressing force of the cleaning element against the inner wall of the spinning rotor and to control the drive in accordance with the pressing force.
  • deviations in cleaning can be determined in comparison with standard values, e.g. damage to the cleaning element or larger foreign objects in the spinning rotor.
  • the cleaning element is moved from its rest position into a first position in a first movement.
  • the first position can already represent the cleaning position. Just like that However, it is conceivable that the first position is located anywhere in the movement sequence from the rest position to the cleaning position.
  • the cleaning element is moved from its first position into a second position by means of a second movement.
  • the second position represents the end position and thus the cleaning position.
  • the direction of movement of the cleaning element during the second movement differs at least in sections from the direction of movement of the first movement.
  • first movement is carried out by the first drive and the second movement by a second drive.
  • second drive it is also conceivable that there is no specific first position due to the superimposition of the first and second movements, so that the cleaning element in one movement, e.g. consists of a simultaneous rotation and swiveling in two different directions, is moved directly into the cleaning position.
  • the direction of movement of the cleaning element during the first and / or second movement is rectilinear, at least in sections.
  • the cleaning element is moved into the interior of the spinning rotor by the first movement and into its cleaning position by the second movement. In the cleaning position, the cleaning element is then in contact with the inner wall of the spinning rotor, in particular in the region of the rotor groove and / or the side wall of the spinning rotor.
  • the first movement can already be carried out during the opening of the closure device of a housing that houses the spinning rotor. After cleaning the spinning rotor, the cleaning element then follows the movement sequence of feeding up to the cleaning position in the opposite direction to return to its rest position.
  • first and / or the second movement is a lifting or swiveling movement.
  • the stroke movement is preferably parallel or at an acute angle to the axis of rotation of the spinning rotor.
  • a pivoting movement can preferably be carried out such that the angle at which the cleaning element stands on the axis of rotation of the spinning rotor can be changed.

  • the movement of the cleaning element through the guide with the respective characteristic movement properties, such as Direction of movement, speed and / or acceleration is carried out by the drive (s) and controlled by the central control of the rotor spinning machine or the corresponding work station.
  • the cleaning element is first moved from its rest position into one of several possible cleaning positions with the aid of a drive of the cleaning unit and after the cleaning process has ended with the aid of an energy store of the cleaning unit, e.g. in the form of a spring element, is guided back to its rest position.

In a second step, the cleaning element is pivoted about its axis of rotation into the center of the spinning rotor. In a further step, the cleaning element is lowered again, as a result of which the tip of the cleaning element is preferably located at the level of the rotor groove. In a last step, the cleaning element is pivoted again about its axis of rotation in the direction of the rotor groove until the cleaning element is in contact with it. By evaluating the drive parameters, the contact pressure of the cleaning element for cleaning the rotor groove can be adjusted.

  • Different run-out and / or start-up methods, for example with the aid of a (variable) ramp function, of the spinning rotor drive are preferably used.
  • the spinning rotor can be cleaned even without a complete stop thereof, which leads to a reduction in the downtime of the spinning rotor.
