Definitions

  • a cage for a pair of pressure rollers of a drafting system of a textile machine is known, the pair of pressure rollers being formed by two top rollers which are freely rotatably arranged on a fixed axis.
  • a fiber structure is stretched in the drafting system.
  • the cage has two guide elements for guiding a guide strap, which partially encloses one of the two top rollers.
  • the cage is fastened to the axle of the pair of pressure rollers with a fastening element.
  • the guide elements for deflecting the guide aprons each have a deflection edge arranged at a distance from the central axis.
  • a spring element for tensioning the respective guide strap is arranged between the guide elements and the respective guide strap.
  • the guide apron or top apron should be guided with the cage as close as possible to the exit nip point of the drafting system.
  • the distance between the exit of the cage and the clamping point between the exit top and exit bottom roller should be as small as possible in order to ensure particularly good guidance of the fiber structure to be drawn.
  • the top strap is pulled around the deflection edge of the cage. Due to the wrapping and the existing friction between the top apron and the deflection edge of the cage, forces occur that act on the cage.
  • the cage should be very stable and deform as little as possible under the load so that the geometric conditions in the main field area of the drafting system change as little as possible.
  • the strap is also tightened in the cage. In the known constructions of tensioning devices, the cage becomes softer in the area of the deflection edge. This is a disadvantage.
  • the WO 2019/016414 A1 discloses a cage arrangement for a drafting system of a spinning machine, with an apron carrier for a first upper apron and a second upper apron, which are provided for supplying a common front roller with two types of fiber strands.
  • the apron carrier comprises a first tensioning device for the first top apron and a second tensioning device for the second top apron, the first and the second tensioning device comprising a first and a second movable tensioning surface.
  • the moveable clamping surfaces are movably mounted on the apron carrier to act independently on the first top apron and the second top apron in moving them into a working clamping position.
  • the clamping surfaces are movably mounted on a common stationary wedge-shaped support of the cage frame in order to be able to assume a clamping working position when rotating about an axis.
  • the wedge-shaped support is formed integrally with the cage frame. It is not possible to exchange the wedge-shaped support.
  • the deflection bar In the cages normally used on the market, the deflection bar is guided linearly and spring-loaded in the direction of the stretching field. With this construction, the position of the deflection edge depends on the length of the top apron and the driving forces that occur. This contradicts the requirement for precise positioning of the deflection edge.
  • the canting and the The associated stiffness in the linear guide in the operating state is another disadvantage.
  • the clamping of the top apron is realized with a bar that is loaded with pressure springs.
  • the disadvantage is the weakening of the base body and the tilting of the clamping bar, which in turn results in sluggishness in the linear guide.
  • the object of the present invention is therefore to create a cage that is stable and in which the strap can be tensioned evenly and the deflection edge can be positioned precisely.
  • the cage for a pair of pressure rollers of a drafting system of a textile machine has a base body with a fastening element for fastening the cage to an axis of the pair of pressure rollers and at least one, preferably two, deflection element(s) for deflecting two guide straps.
  • the deflection element is fastened to the base body and two tensioning elements are arranged on the base body for tensioning the respective guide strap.
  • the tensioning elements are rotatably mounted and each tensioning element is fastened to the base body together with the deflection element.
  • the tensioning elements Due to the rotatable mounting of the tensioning elements, they can be moved easily and tilting of the tensioning elements when a force is exerted by the guide strap on the tensioning element is reliably avoided. With the attachment of each tensioning element to the deflection element on the base body, the base body can be designed to be extremely stable.
  • the attachment of the tensioning element to the deflection element on the base body also reinforces the base body, so that additional stability of the cage is generated. This ensures that the deflection edge can be positioned exactly. The result of the drafted fiber structure in the drafting system is thus significantly improved.
  • the deflection element is clamped, in particular clipped, on the base body. Fast and reliable attachment is made possible by this attachment of the deflection element to the base body.
  • the clip connection also allows the deflection element to be detached easily and quickly from the base body, as a result of which the deflection element or the tensioning element can be easily replaced if necessary.
  • the clamping elements are rotatably mounted on the base body.
  • the respective guide strap is tensioned by turning the tensioning elements. Tilting of the tensioning elements during rotation is avoided and the guide straps can be tensioned evenly.
  • the tensioning element is a flap.
  • the flap can be set up more or less in relation to the base body, so that the guide strap is sufficiently tensioned.
  • the tensioning element has a roller-shaped articulated head.
  • the roller-shaped joint head ensures that the guide apron can be tensioned evenly.
  • the clamping element rotates around the roller-shaped joint head and is positioned more or less in relation to the base body.
  • the tensioning element is rotatably mounted with the joint head in a trough-shaped socket of the base body.
  • a secure rotary movement of the tensioning element relative to the base body is thus made possible, which avoids tilting of the tensioning element and thus enables uniform tensioning of the guide strap.
  • the deflection element encompasses the roller-shaped articulated head of the tensioning element.
  • the fastening of the tensioning element on the base body is realized in a particularly simple manner as a result.
  • the tensioning element is connected to the base body on the one hand and retains its rotational mobility on the other hand.
  • the deflection element is attached to the base body.
  • a spring in particular a torsion spring, is advantageously arranged between the base body and the tensioning element.
  • the spring causes the tensioning element to be spread apart relative to the base body.
  • the guide strap which rests on the tensioning element, is thus tensioned and can guide the fiber structure very precisely.
  • the legs of the torsion spring are supported on the base body and the tensioning element. Due to the effort of the torsion spring to widen, the tensioning element is spread apart from the base body. When the guide strap lies on the tensioning element, this is tensioned in relation to the deflection element and the top rollers and thus ensures reliable guidance of the fiber structure and an exact position of the deflection edge.
  • the spring is guided axially in a recess or on a projection of the base body and/or the tensioning element. It can thus be ensured that the tensioning element cannot be displaced in the axial direction by the small guide strap. The exact position of the guide apron is maintained during spinning. In particular, with the deflection element clipped on, the torsion spring and the tensioning element are "caught" in the base body.
  • the fastening element has a lug for axially fixing the cage in relation to a recess on the axis of the pair of pressure rollers.
  • the projection rests against the edges of the recess and thus positions the cage in the axial direction in relation to the top rollers.
  • the cage can be fastened to the axle quickly and precisely by clipping it on.
  • the clamping element is wider than the distance between the two delimiting webs.
  • the clamping element should have a length that is significantly greater than the distance between the two delimiting webs. This achieves the particular advantage that the delimiting webs can be arranged at different points on the tensioning element. This can be at different distances between the spinning positions, which which are assigned to the guide straps run on the cage, are received and the optimal positioning of the guide straps takes place without the entire cage having to be replaced. To adapt to the spinning machine on which the cage is to be used, it is accordingly sufficient that only the appropriate clamping elements are mounted on the base body.
  • the delimiting webs are optionally arranged essentially centrally or laterally offset on the tensioning element. If the delimiting webs are arranged on the tensioning element in such a way that they are close to the neighboring tensioning element, a small distance between neighboring spinning positions can thus be served. If, on the other hand, the delimiting webs of adjacent tensioning elements are at the greatest possible distance on the tensioning elements, then a greater distance between adjacent spinning positions can be provided. With a central arrangement of the delimiting webs, a medium distance between adjacent spinning positions is advantageous.
  • the cage length can be varied, viewed in the stretching direction of the fiber structure. With a small width of the deflection elements, a short cage length is achieved, whereas with a large width of the deflection elements, a large cage length is made possible.
  • figure 1 shows a side view of a drafting system of a textile machine, preferably a ring spinning machine, in the area of a cage 1 and a pair of output rollers 2.
  • the cage 1 is provided for two adjacent drafting system units of the drafting system.
  • the cage 1 is attached to an axle 3 of a pair of pressure rollers, of which only one pressure roller 4 is visible in this representation.
  • the pair of pressure rollers is designed as a twin roller, in which two pressure rollers 4 are arranged at a distance from one another and are freely rotatable on the fixed axle 3 .
  • the pair of pressure rollers is held via the axis 3 in a load carrier, not shown, of the drafting system.
  • the pressure roller 4 is driven by the load carrier, not shown, against a driven and stationarily mounted lower roller 5 is pressed so that an incoming fiber structure 6 is clamped between the pressure roller 4 and the lower roller 5 .
  • the fiber structure 6 as well as the pressure roller 4 is carried along by the lower roller 5, which extends over several adjacent drafting units, by frictional engagement.
  • the pressure roller 4 and the lower roller 5, which form a central roller pair are followed by the output roller pair 2, which is also arranged on the loading carrier.
  • the output roller pair 2 is driven at a higher peripheral speed than the center roller pair.
  • the drafting system can contain further pairs of rollers, not shown.
  • a fiber guide device is arranged in the main drafting zone of the drafting system so that a uniform draft of the fiber structure 6 is achieved and faulty drafts of the fiber structure 6 are avoided.
  • the fiber guide device comprises an upper guide strap 7 and a lower guide strap 8 . Between the guide straps 7 , 8 the fiber structure 6 is guided.
  • the lower apron guide 8 is arranged on the underside of the drafting system and runs around a deflection edge of a stationary lower apron guide 9 and partially wraps around the lower roller 5 of the middle roller pair.
  • the lower apron guide 9, like the lower roller 5, extends over several adjacent drafting systems.
  • the lower guide strap 8 is driven via the lower roller 5.
  • the upper guide strap 7 runs around the cage 1 and partially wraps around the pressure roller 4.
  • the upper guide strap 7 is driven via the lower guide strap 8, which is in frictional contact with it.
  • cages 1 of different geometry or width are in the fiber guide device usable. This makes it possible to specifically change the path along which the fiber structure is guided through the guide aprons 7, 8 in the main drafting zone.
  • the purpose of the cage 1 is to guide the upper guide strap 7 as close as possible to the output nip point of the drafting system at the output roller pair 2 .
  • the distance between the exit of the cage 1 and the nip point at the exit roller pair 2 should be as small as possible.

  • the fastening element 10 is used to fasten the cage 1 to the stationary axle 3 of the pair of pressure rollers 4.
  • the fastening element 10 has a receptacle 14 via which the cage 1 can be easily clipped to the axle 3 of the pair of pressure rollers 5 and released again.
  • the deflection element 13 has a deflection edge 15 for deflecting the guide apron 7 .
  • the tensioning element 12 is pretensioned with a spring 16 and serves to tension the guide strap 7.
  • the clamping element 12 is designed in the form of a flap. It is rotatably mounted on the base body 11 .
  • the clamping element 12 has a roller-shaped joint head 17 at one end.
  • the cylindrical joint head 17 is located in a trough-shaped socket 18 of the base body 11.
  • the joint head 17 can rotate in the socket 18 about the axis of the cylindrical joint head 17, so that the clamping element 12 is spread more or less in relation to the base body 11.
  • the spring 16 is provided, which elastically pretensions the tensioning element 12 .
  • the spring 16 is designed as a leg spring, with one of the two legs being arranged in a recess 19 in the base body 11 .
  • the leg can be supported in the recess 19 against the base body 11 .
  • the spring 16 is fixed axially by the recess 19 so that it cannot fall out of the base body 11 laterally.
  • the other leg of the spring 16 is supported on the tensioning element 12 .
  • a projection 20 is provided on the underside of the clamping element 12 .
  • the leg of the spring 16 is supported on this projection 20 in the axial direction, so that the spring 16 and the tensioning element 12 are also fixed axially relative to the base body 11 as a result.
  • the deflection element 13 is provided for fastening the roller-shaped joint head 17 in the trough-shaped socket 18 .
  • the deflection element 13 is attached to the base body 11 by means of a clip connection.
  • the deflection element 13 grips the underside of the base body 11 with a claw 21.
  • the other end of the deflection element 13 grips the cylindrical joint head 17 of the tensioning element 12 with a clamp 23.
  • the deflection element 13 thus acts as a type of clamp which clamps the tensioning element 12 on the base body 11 holds.
  • it completes the swivel joint for the tensioning element 12 by pressing the joint head 17 into the socket 18 so that it can rotate.
  • the clamping element 12 is rotatably mounted and can apply the required pressure to the guide strap 7 without getting caught.
  • the base body 11 can be constructed very stably. It is not weakened by the functional elements arranged on it--clamping element 12 and deflection element 13--in particular by deflection element 13 it is even additionally reinforced.
  • the spring 16 takes up only a small amount of space, as a result of which the base body 11 can be made largely solid.
  • FIG 2 is a perspective view of an embodiment of a cage 1 is shown.
  • the cage 1 has the fastening element 10 and the base body 11, which are connected to one another in one piece. Of course, it would also be possible to make them detachable from one another.
  • This illustration shows that the cage 1 is provided for two guide straps 7 (not shown here) running parallel to one another. Accordingly, the cage 1 has two tensioning elements 12 and two deflection elements 13 .
  • the respective clamping element 12 is formed with the roller-shaped joint head 17 which is rotatably mounted in the trough-shaped socket 18 .
  • the socket 18 is part of the base body 11.
  • the deflection element 13 grips the roller 17 at both ends of the tensioning element 12 with a clamp 23.
  • the spring 16 is not visible in this illustration, which is located between the clamping element 12 and the base body 11.

  • the tensioning element 12 has two delimiting webs 22 in this representation.
  • the delimiting webs 22 are intended for the guide strap 7 to be guided laterally in the axial direction between them. Accordingly, the width of the guide strap 7 is approximately equal to the distance a between the two delimiting webs 22 of the tensioning element 12 (see FIG Figures 3a to 3c ).

  • roller-shaped joint head 17 When depicting the Figures 3a to 3c the roller-shaped joint head 17 can also be seen in dashed lines.

In this embodiment, a central fastening with a clamp 23 is also provided, since the clamping element 12 is very long. As a result, a deformation of the tensioning element 12 when guiding the guide strap 7 is reliably avoided.
  • deflection elements 13 have a different width B. In this way, the special requirements of different fiber strands 6 can be addressed and the nip point of the fiber guide device in the main drafting zone or the distance of the guide from the nip point of the output roller pair 2 can be varied. A replacement of the entire cage 1 or the clamping element 12 is not required for this. It is sufficient to use the appropriate guide element 13.
