Definitions

  • DE-A 42 24 687 is a method known for open-end spinning and an open-end spinning device, at of the fibers emerging from the fiber feed channel to a first Wall arranged perpendicular to the rotor axis are fed, whereby they are arranged compressed in the plane of this area, while the Transport air is separated from the fibers. Then the fibers are on the sliding wall of the spinning rotor, viewed in the axial direction of the spinning rotor fed. The fibers then slide down along the sliding wall into the fiber collecting groove of the spinning rotor. From there they are in the forming Thread tied in and pulled out of the rotor.
  • Another disadvantage of the prior art open-end spinning devices Technique is that the fibers are fed directly into the fiber collecting groove this prevents a shortening of the distance between the fiber collecting groove and the end of the sliding surface is not possible at all.
  • the open-end spinning rotors of the prior art have namely their open end such a small diameter, due to the Inclination and in particular length of the fiber sliding wall in the axial direction seen that the diameter of the part extending into the spinning rotor the lid of the open-end rotor spinning device a much smaller one Diameter must have than the fiber collecting groove of the spinning rotor.
  • the prior art has for the purpose of saving energy in DE-A 23 01 439 proposed the diameter of the fiber collecting groove in one determined ratio of the distance of the fiber collecting groove to the edge of the Form spinning rotor.
  • rotors for high rotor speeds of approx. 100,000 rpm and more are these dimensions however, to be regarded as unusable and cannot teach the expert with regard to the formation of a spinning rotor.
  • a height h as in DE-A 23 01 439 is defined, of about 10 mm. This would be for the real diameter mean that a suitably trained spinning rotor has a diameter should have in the area of the fiber collecting groove of 70 mm.
  • the teaching DE-A 23 01439 is not applicable because it related to spinning rotors with diameters in the area of the fiber collecting groove from the then usual Values of well over 45 to 50 mm in diameter in the area of the fiber collecting groove.
  • the prior art has, unlike in DE-A 23 01439 taught, developed in such a way that the average height h regardless of The diameter of the fiber collecting groove was chosen to be the same size, with values in the range from 9.5 mm to 11.5 mm were used for diameters the fiber collecting groove between 30 mm and approx. 40 mm.
  • For the rest are in the DE-A 23 01 439 has no information at all regarding the feeding of Fibers made in the spinning rotor, so from this prior art no suggestions in the development of spinning rotors, which at higher Speeds can be used.
  • the object of the present invention is an open-end spinning rotor to train that the disadvantages of the prior art are overcome and the configuration according to the invention makes it possible to use the fibers feed into the spinning rotor in a favorable way, so that spinning rotors with a diameter of approx. 30 mm and used far below can be.
  • This has the particular advantage of being economical of open-end rotor spinning can be increased significantly because of especially small rotors significantly increase the production speed of the thread can be increased.
  • Another object of the present application is an open-end spinning rotor propose that used particularly cheap at high speeds can be, with speeds of far more than 130,000 rpm should be possible and at the same time the spinning rotor with less Use of drive energy to be operated, it has a lower mass should have and have good center of gravity because the focus more near the bearing of the spinning rotor.
  • the invention of the present application is based inter alia on the finding from the fact that contrary to the ideas of the state de Technique essentially sliding the fibers along the wall of the spinning rotor does not lead to the desired effect, namely that the fibers so involved in the yarn that this is a satisfactory Maintains structure.
  • so-called belly bandages that is fibers, which are wrapped around the yarn instead of part of the fiber composite to be cannot be diminished or avoided.
  • the fibers become long to slide along the fiber sliding wall, placed parallel in the fiber collecting groove.
  • a favorable orientation of the fibers is due to the only slight or completely eliminated glide path on the wall of the spinning rotor more resolved so that the fibers are better parallelized and oriented to each other are.
  • the fibers come with their beginning and end lying in one plane in the fiber collecting groove. This will increase the number of so-called belly bandages are reduced because there are fewer thread starts in the thread be integrated as long as their ends are not yet in the fiber collecting groove are located.
  • the wall of the spinning rotor is located inside extends from the fiber collecting groove to the edge, an inclination in relation to the axis of rotation of the spinning rotor from 15 'to 21'. This will ensures that the fibers reach the fiber collecting groove safely and quickly, even if the wall is rough.
  • the wall of the spinning rotor is rough, for example by means of a coating with hard particles, e.g. Diamond.
  • the open-end spinning rotor has a fiber collecting groove with a diameter of less than 35 mm. This makes it possible to design a particularly economical embodiment of the invention. The advantages of the invention are particularly evident when the Fiber collecting groove has a diameter of less than 30.5 mm.
  • the open-end spinning rotor is advantageously designed if it has one Has shaft for storage and / or for its drive. This is the rotor easy to replace and to drive as well as slow down.
  • the spinning rotor is on its opposite end from the open end Side is equipped with a storage surface, for example, disc-shaped can be configured and made of a magnetizable material can be., causing the spinning rotor over electromagnetic forces can be stored as well as driven. This makes it special high speeds possible.
  • the spinning rotor can also advantageously be equipped with openings in its rotor base, which in known As a result of the rotation of the rotor, a vacuum is created in it and extra measures for generating a negative pressure can be saved can.
  • the inventive design of the open-end spinning rotor achieved that the spinning rotor is particularly economical at high speeds can be used. Due to the low height of the wall between the fiber collecting groove and opening of the spinning rotor is achieved that its surface is relatively small. which leads to be - especially at high speeds Air resistance to the spinning rotors of the prior art strong is reduced. This is further compounded by its smaller diameter in the area the fiber collecting groove also supports. Nevertheless, the spinning rotor has an opening into which, for example, the approach with a fiber feed channel and extends into the feed surface of an open-end spinner that is large enough so that the parts of the open-end spinning device can be formed in sufficient size so that the feed the fibers are not hindered, neither is the pulling of the thread.
  • the spinning rotor By designing the size of the opening of the Spinning rotor compared to the diameter of the fiber collection groove achieved that with the same size of the approach of the open-end spinning device a spinning rotor with a smaller fiber collection groove than i State of the art can be used, resulting in higher rotor speeds and thus thread delivery speeds are possible. This increases not only the economic advantage because less drive energy is used , but also the productivity of the spinning rotor is significantly improved.
  • the spinning rotor also has the property that the Wall is formed with such a low height that the orientation of the fed Fibers are not significantly deteriorated by the wall of the spinning rotor becomes.
  • the fibers can be easily accessed through its opening geometry and its low height close to the wall in the area of Fiber collection groove are fed, even directly into the fiber collection groove itself. This has particularly favorable effects on the quality of the spun Thread. In this context, it is also particularly favorable the distance between the bottom of the spinning rotor to the plane in which the fiber collecting groove is arranged. This makes it possible to withdraw the thread to design from this spinning rotor so that the drawn thread does not come into contact with the fed fibers. Such a rotor is less prone to the formation of tummy tucks in the yarn.
  • the wall of less than 6, 1 mm is achieved that the above Advantages can be increased even further, a low one is particularly favorable Wall height of less than 4.1 mm, favorable between 2 mm and 6 mm located and particularly cheap in a range between 2.2 mm and 4.2 mm.
  • the fiber collecting groove has a diameter between 32 mm and 30.5 mm
  • the Opening of the rotor has a diameter of at least 25.7 mm, because this creates a particularly economical spinning rotor can be, which at the same time has such a large opening that it can be easily loaded with fibers because the approach that goes into it can be trained large enough.
  • the fiber feed channel can keep an advantageous size.
  • An open-end spinning rotor is particularly economical use according to the invention if it has a diameter the fiber collecting groove in the range between 27.5 mm and 30.5 mm owns. As a result, rotor speeds of far more than 130,000 rpm possible, which makes a particularly economical rotor becomes. Especially in connection with a low height of the wall of the An open-end spinning rotor can thus be used to obtain a rotor that simultaneously a high quality thread and it is particularly economical can manufacture. With the configuration according to the invention it is also possible to design rotors with extremely high rotor speeds can work, and despite a diameter of the fiber collecting groove of less than 27.5 mm can still be adequately supplied with fibers.

  • the fibers in a region of the wall 113 between the fiber collecting groove 112 and the edge 119 are fed, for example with a distance to the fiber collecting groove between 1 mm and 2.8 mm. From there the fibers then get into the. without sliding large on the wall 113 Fiber collecting groove 112.
  • the distance of the neck 3 to the wall 113 or fiber collecting groove 112 of the spinning rotor 11 can be designed asymmetrically, so that the distance on the side where the fibers get into the spinning rotor is designed to be significantly smaller than on the one facing away from it Page. This makes it easier for the air that has entered the rotor to escape from it emerge.
  • the lid is on the hinge 22 pivoted, causing the end of the feed surface 32 in the area the wall 113 arrives at the edge 119 of the spinning rotor.
