Definitions

  • the present invention relates to an opening roller housing, in the area one insert in the direction of rotation of the opening roller after the tape feed is arranged according to the preamble of claim 1 and a Insert for an opening roller housing according to claim 4 and a method to modernize an open-end spinning device, using an Opening roller housing removed and then by an insert according the invention is replaced, according to claim 15.
  • Opening roller housings are widely known from the prior art, for example also by the spinning units SE7, SE8 and SE9 of the rotor spinning machine Autocoro by W. Schlafhorst AG & Co, 41061 Mönchengladbach, DE.
  • the opening roller housing of these spinning units consist of essentially consisting of individual segments arranged on a carrier plate are. Form the individual segments placed on the carrier plate thus the peripheral wall of the opening roller housing, also in the area between the feeding of the sliver and the dirt discharge opening of the opening roller housing.
  • This type of design of an opening roller housing has the consequence that in the area after the entry of the sliver due to the negative pressure, which continues from the rotor housing to the opening housing, sucked in a lot of air becomes.
  • the opening roller housing in the area of dirt separation The amount of air supplied can only be via the negative pressure the spinning chamber can be controlled.
  • This device has the general Disadvantage that always in relation to the air actually required too much is supplied to the opening roller housing, so that the supplied air can lead to difficulties in the opening roller housing itself.
  • the unpublished German application DE 102 24 589.4 describes an opening roller housing in which the peripheral wall of the opening roller housing between the dirt separator and the discharge opening for fibers is formed by an interchangeable insert. This is supposed to Dirt separation can be adapted to different fibers.
  • the Opening roller housings of the prior art have the disadvantage that Although the size of the dirt separation can be varied, however the known inserts not suitable opening roller housing variable train, so that this on different fiber materials and others Spinning conditions can be adjusted. Can also with the known Segments of the dirt separation area are not formed in this way be that the opening roller especially covered in the area of their shelves is. In addition, the size of the dirt separation opening can only be insufficiently changed in size, especially their location also in relation to the fiber feed (feed opening in the opening roller housing) unchangeable.
  • the object of the present invention is therefore an opening roller housing propose that avoids the disadvantages of the prior art and propose an insert that is suitable for the opening roller housing to adjust to different spinning conditions through its exchange.
  • Another task is to propose a method, the open-end spinning devices modernize the state of the art.
  • an insert according to the invention according to claim 4 can an opening roller housing in a simple way to different spinning conditions be adapted as well as an opening roller housing according to the state of the Technology can be modernized using the inventive method.
  • the opening roller housing in this way can be configured that now the supply of air into the opening roller housing can be better controlled and the location on the opening roller housing, where this takes place.
  • the air budget of the opening roller housing can be significantly improved.
  • Another advantage results differs in that with the help of the invention existing columns between Opening roller housing and opening roller also in the area of dirt separation can be covered to clamp fibers in the Avoid the area of the columns of dirt separation.
  • the insert designed according to the invention has the advantage that the insert the peripheral wall of the opening roller housing also in the area of the dirt separating opening has, so that also in the area of the dirt separation opening the board of the opening roller is covered, creating the peripheral wall of the opening roller housing in this area only that part of the Leaves opening roller, which are provided with a set. It has an advantage Opening roller housing after the dirt separation a stop for use, so that this in the area where it with the other components of the opening roller housing comes into contact, can be positioned.
  • the extension is made by forming a sliver support on the insert the combing zone for the sliver following the feed of the sliver advantageously reached in the opening roller housing, so that the amount of dirt excreted when the sliver breaks up quality, i.e. less good fibers are excreted without separating the light dirt components is adversely affected by this.
  • the insert with at least a fork-shaped extension is advantageously achieved that the peripheral wall of the opening roller housing in the area of the dirt separation opening Can be trained using the insert according to the invention.
  • the fork-shaped extensions can be the size of the Dirt excretion in its width exactly to the width of the set Opening roller to be matched.
  • the insert can also have two fork-shaped ones Have extensions so that the left and right boundaries of the Dirt separating opening is formed by the insert.
  • the insert contains the dirt separation opening, which also means the area after the Dirt separating opening, viewed in the direction of movement of the fibers, on Use can be designed. This enables this area too for example in the form of coatings or other geometric Embodiments can be adapted to different spinning conditions can.
  • the area after dirt removal is also subject to some Fibers increased wear, causing wear in this Area does not result in the entire opening roller housing being replaced needs to be. A new insert in the opening roller housing is then sufficient use.
  • the use in Area of the air supply at the dirt separation opening is rounded Edges to allow access to the air that takes place in this area to ensure undisturbed flow.
  • the Insert is arranged interchangeably on the opening roller housing, in particular if it has fasteners, for example in the form of Bores or similar can be designed. Due to the design, where the use in the area of the dirt separator opening the board of the Opening roller covers, is advantageously achieved that no fibers in this Area too far outside of the clothing room. With a cheap Design, the fork-shaped extensions have a contact surface with which they rest on the opening roller housing. This makes positioning accurate Determination of the use possible.
  • the method according to the invention ensures that the open-end spinning device of the prior art processed in such a way and thus can be modernized so that they correspond to the state of the art and a controlled air supply in the area of dirt separation own, also in the area after feeding the sliver. About that it is also possible to influence the size of the dirt separation to take as well as on the peripheral wall of the opening roller housing before and after dirt separation. Further advantageous configurations of the invention are in the subclaims or dependent claims described.
  • FIG. 1 shows a side view of the invention Opening roller housing with an inventive use, wherein the opening roller is removed from the housing.
  • the opening roller housing 1 has a round opening 14 through which in operation, a shaft protrudes on which the opening roller is attached is.
  • the opening roller housing 1 has a feed opening 2 through which the intended to dissolve sliver (not shown) using a Feed shaft 15 is transported into the opening roller housing 1.
  • the Feed shaft 15 works in a known manner with a feed trough 16 together, the sliver between by means of elastic elements 17 himself and the feed shaft 15, so that between the sliver and Feed shaft no slippage occurs and the sliver controls the opening roller housing 1 can be supplied.
  • the opening roller housing After use 5 in the circumferential direction of arrow P, the opening roller housing again a peripheral wall 11 which merges into a discharge opening 3, by the isolated fibers from the opening roller housing in a known manner 1 are removed, whereupon they become a spinning organ, for example, an open-end spinning rotor.
  • the discharge opening goes into a fiber feed channel 31.
  • the discharge opening 3 viewed in the direction of rotation P of the opening roller, has the opening roller housing the peripheral wall 11, which extends to the feed opening 2.
  • the insert 5, the between the feed trough 16 and a stop 41 of the Opening roller housing 1 is arranged with the aid of fasteners 6, for example screws or dowel pins, on the side wall 18 of the Opening roller housing 1 is attached interchangeably.
  • a streamlined small Gap in the peripheral wall 11 of the opening roller housing which is conditional due to the necessary mobility of the feed trough 16.
