Description
Technical Field
The invention relates to a holder for a roller pair of a drafting device of a textile machine, wherein the holder has a base body, a fastening element for fastening the holder to a shaft of the roller pair, and at least one, preferably two, deflection elements for deflecting two guide aprons, wherein the deflection elements are fastened to the base body, and two tensioning elements are provided on the base body for tensioning the respective guide aprons.
Background
CH 711154 a1 discloses a holder for a pressure roller pair of a drafting device of a textile machine, wherein the pressure roller pair is formed by two upper rollers which are freely rotatably arranged on a fixed shaft. The fiber bundle is drawn in a drawing device. The cage has two guide elements, each for guiding a guide apron, which partially surrounds one of the two upper rollers. The holder is fixed to the shaft of the pair of pressure rollers by means of a fixing element. The guide elements for deflecting the guide leather collar each have a deflection edge arranged at a distance from the central axis. A spring element for tensioning the respective guide apron is arranged between the guide element and the respective guide apron.
With the aid of the holder, it is desirable to guide the guide apron or the upper apron as close as possible to the output clamping point of the drafting device. The distance between the output of the cage and the clamping point (between the upper output roller and the lower output roller) should be as small as possible to ensure an excellent guidance of the drawn fiber strand.
The upper collar is drawn around the deflecting edge of the cage. The force acting on the cage is generated on the basis of the surrounding, and the existing friction between the top leather collar and the deflecting edge of the cage. The holder should be very stable and deform as little as possible under load so that the geometrical changes in the main span region of the drawing frame are as small as possible. The apron is also tensioned in the cage. In the known tensioner configuration, the cage is softer in the region of the deflecting edge. This is a drawback.
In the holders usually used on the market, the deflection bars are guided in a straight line and spring force is applied to the drafting zone. With this configuration, the location of the deflecting edge is related to the length of the upper loop and the driving force generated. This is in contradiction to the requirement for accurate positioning of the deflecting edge. Tilting in the operating state and the accompanying poor operation in linear guide systems are another drawback.
In a further embodiment of the cage, the tensioning of the upper leather collar is effected by means of a strip which is acted upon by a compression spring. The disadvantage is the weakening of the base body, the inclination of the tension strips and the accompanying poor operation in the linear guide system.
Disclosure of Invention
It is therefore an object of the invention to provide a cage which is relatively stable and in which the apron can be tensioned uniformly and the deflecting edge can be positioned precisely.
The solution of the present invention to achieve the above object is a cage.
According to the invention, the holder is directed to a roller pair of a drafting device of a textile machine, comprising a base body, a fastening element for fastening the holder to a shaft of the roller pair, and at least one, preferably two, deflection elements for deflecting two guide aprons. The deflection element is fixed to the base body, on which two tensioning elements are arranged for tensioning the respective guide apron. According to the invention, the tensioning elements are rotatably mounted, each tensioning element being fastened to the base body together with the deflection element.
By rotatably supporting the tensioning element, the tensioning element is easy to move and wherein tilting of the tensioning element is reliably avoided in the case of a force being exerted on the tensioning element by the guide apron. By fixing each tensioning element to the base body by means of the deflection element, the base body can be made extremely stable. Furthermore, the fastening of the tensioning element to the base body by means of the deflection element reinforces the base body, so that the stability of the cage is additionally increased. This ensures that the deflecting edge can be positioned accurately. The result of the drawing of the drawn fiber strand in the drawing frame is thereby significantly improved.
Particularly preferably, the deflection element is clamped, in particular snapped, onto the base body. By thus fixing the deflection element to the base body, a quick and reliable fixing is achieved. The snap-fit connection also enables a simple and quick separation of the deflection element from the base body, so that the deflection element or the tensioning element can be easily replaced if necessary.
Particularly preferably, the tensioning element is rotatably mounted on the base body. The respective guide apron is tensioned by rotation of the tensioning element. Tilting of the tensioning element during rotation is avoided and the guide apron can be tensioned uniformly.
The tensioning element is preferably a flap. The flap can stand more or less upright relative to the base body, so that the guide leather collar is sufficiently tensioned.
Particularly preferably, the tensioning element has a roller-shaped joint. The roller-shaped joint causes a linear movement of the tensioning element, so that a uniform tensioning of the guide apron can be achieved. Wherein the tensioning element rotates around the roller-shaped joint and stands more or less upright relative to the basic body.
It is also preferred that the tensioning element is rotatably mounted in a groove-like bearing of the base body by means of the joint head. In particular, in combination with the roller-shaped joint, a safe rotational movement of the tensioning element relative to the base body is achieved, which prevents tilting of the tensioning element and thus a uniform tensioning of the guide apron.
Furthermore, the deflection element preferably buckles the roller-shaped joint head of the tensioning element. The fastening of the tensioning element to the base body is thereby achieved in a particularly simple manner. By looping the roller-shaped joint head by means of the deflection element, the tensioning element is connected to the base body on the one hand and is provided with a rotationally movable characteristic on the other hand. While the deflection element is fixed to the base body. The connection of the base body to the tensioning element and the deflection element provides a particularly stable holder which achieves a precise positioning of the deflection edge which holds its position very precisely even under the intended application of force.
Preferably, a spring, in particular a leg spring, is provided between the base body and the tensioning element. The spring causes the tensioning element to expand relative to the base body. The guide apron bearing against the tensioning element is thereby tensioned and can guide the fiber bundle very precisely.
Preferably, the legs of the leg spring are supported on the base body and on the tensioning element. In the event of an attempted expansion of the leg spring, the tensioning element is splayed from the base body. In the case of a guide apron resting on the tensioning element, the guide apron is tensioned against the deflection element and the upper roller, so that a reliable guidance of the fiber strand and a precise position of the deflection edge are achieved.
Particularly preferably, the spring is guided axially in a recess or on a projection of the base body and/or the tensioning element. This ensures that: the tensioning element is not moved axially by the guide apron. Wherein the precise position of the guide apron is maintained during the spinning operation. In particular, the torsion spring and the tensioning element are "captured" in the base body by the snap-in deflection element.
Preferably, the fixing element has a flange for axially fixing the cage on the shaft of the pair of pressure rollers relative to the annular groove. The protruding portion is located on the edge of the annular groove, and therefore the retainer is axially located relative to the upper roller. Therefore, the retainer can be fixed to the shaft quickly and accurately by the snap fit.
It is also particularly preferred if two delimiting webs are provided on the tensioning element for lateral guidance of the guide apron. Wherein the guide apron is located between the two delimitation pieces. Thereby preventing the guide leather collar from moving axially out of the predetermined position.
Preferably, the width of the tensioning element is greater than the distance between the two delimiting pieces. Wherein the length of the tensioning element should be much greater than the distance between the two delimitation pieces. This makes it possible to arrange the delimiting pieces in different positions on the tensioning element particularly advantageously. This makes it possible to cope with different distances of the spinning positions corresponding to the guided guide aprons on the holder and to achieve optimum positioning of the guide aprons without having to replace the entire holder. Accordingly, it is sufficient to mount only the matching tensioning element on the base body in order to be adapted to the spinning machine in which the holder is intended to be used.
Furthermore, it is preferred that the delimiting piece is arranged selectively substantially centrally or laterally offset on the tensioning element. If the delimiting sheet is arranged on the tensioning elements in such a way that it lies close to one another on adjacent tensioning elements, a smaller distance between adjacent spinning positions can be achieved thereby. A greater distance of adjacent spinning positions is achieved if the delimiting pieces of adjacent tensioning elements are located on the tensioning elements with as great a distance as possible. In the case of a centrally arranged delimiting piece, a moderate distance of adjacent spinning positions is advantageously achieved.
In the case of selective fastening of deflecting elements having different widths to the base body, the length of the cage can be varied accordingly in the direction of stretching of the fiber strand. A shorter cage length is achieved with a smaller width of the deflection element, while a larger cage length is achieved with a larger width of the deflection element.

Detailed Description
In the following description of the illustrated embodiments, the same reference numerals are used for features that are identical and/or at least similar in technical solution and/or operating principle, even if these features are disclosed in different embodiments. If these features are not explained in detail again, their technical solutions and/or operating principles are equivalent to those of the features already described above.
Fig. 1 is a side view of a drawing frame of a textile machine, preferably a ring spinning machine, in the region of a holder 1 and a pair of delivery rollers 2. The holder 1 is designed for two adjacent drafting device units of the drafting device. The holder 1 is fixed to the shaft 3 of the press roll pair, of which only one press roll 4 is shown in this figure. The pair of press rolls is designed as a twin roll, two press rolls 4 being arranged at a distance from one another and freely rotatably on a stationary shaft 3. The pair of press rolls is held by a shaft 3 on a not shown load carrier of the drafting device. The press roll 4 is pressed by a load carrier, not shown, against the driven and fixedly supported lower roll 5, so that the entering fiber bundle 6 is sandwiched between the press roll 4 and the lower roll 5. The fiber bundles 6 and the press rolls 4 are carried along by friction fit by means of lower rolls 5 which extend through several adjacent drafting devices. In the drafting device, downstream of the pressure roller 4 and the lower roller 5 forming a central roller pair, there is provided a take-off roller pair 2, which is likewise arranged on the load carrier. The pair of output rollers 2 is driven at a higher circumferential speed than the pair of center rollers. Between the central roller pair and the delivery roller pair 2, a so-called main drawing zone is provided, in which the fiber bundle 6 is drawn such that a thinner fiber bundle 6 is present after both roller pairs. The drafting device may comprise other pairs of rollers not shown.
In order to achieve a uniform drawing of the fiber bundle 6 and to avoid incorrect drawing of the fiber bundle 6, a fiber guiding device is provided in the main drawing zone of the drawing device. The fibre guide comprises an upper guide apron 7 and a lower guide apron 8. The fiber bundle 6 is guided between guide aprons 7, 8. A lower guide apron 8 is arranged on the bottom side of the drafting device and extends around the deflecting edge of a fixed lower apron guide 9 and partially surrounds the lower roller 5 of the central roller pair. The lower apron guide 9 extends like the lower roller 5 over several adjacent drafting devices. The lower guide apron 8 is driven by the lower roller 5. The upper guide apron 7 extends around the holder 1 and partially surrounds the pressure roller 4. The upper guide apron 7 is driven by a lower guide apron 8 which is in frictional engagement with the upper guide apron.
In order to be able to process fibers having different fiber lengths, holders 1 having different geometries or widths can be inserted into the fiber guiding device. This makes it possible to vary the course of the fiber strand guided by the guide aprons 7, 8 in the main drawing zone in a targeted manner. That is, it is desirable to guide the upper guide apron 7 by means of the cage 1 as close as possible to the delivery nip of the drafting device at the delivery roller pair 2. The distance between the output of the cage 1 and the pinch point at the pair of output rollers 2 should be as small as possible.
The cage 1 is substantially formed by a fastening element 10 and a base body 11 which are connected in one piece. A tensioning element 12 and a deflection element 13 are arranged on the base body 11. The guide apron 7 surrounds the pressure roller 4 and the deflection element 13 and is tensioned by the tensioning element 12. The fastening element 10 serves to fasten the holder 1 to the fixed shaft 3 of the pressure roller pair 4. The fastening element 10 has a receiving opening 14, by means of which the holder 1 can be easily snapped onto the shaft 3 of the pair of pressure rollers 5 and separated again. For deflecting the guide apron 7, the deflecting element 13 has a deflecting edge 15. The tensioning element 12 is prestressed by a spring 16 and serves to tension the guide apron 7.
The tensioning element 12 is constructed in the form of a flap. The tensioning element is rotatably mounted on the base body 11. For this purpose, the tensioning element 12 has a roller-shaped joint 17 at one end. The roller-shaped joint 17 is located in a groove-shaped seat 18 of the basic body 11. The roller-shaped joint 17 can be rotated in the bearing 18 about the axis of the roller-shaped joint 17, so that the tensioning element 12 is more or less spread apart relative to the basic body 11.
In order to be able to apply a tensioning force to the guide apron 7, a spring 16 is provided, which elastically pretensions the tensioning element 12. The spring 16 is designed as a leg spring, wherein one of the two legs is arranged in a recess 19 of the base body 11. The legs can be supported in the recesses 19 relative to the base body 11. Furthermore, the axial fixation of the spring 16 is achieved by the recess 19, so that the spring does not laterally escape from the base body 11. The other leg of the spring 16 is supported on the tensioning element 12. In order to maintain the axial position also in this case, a projection 20 is provided on the underside of the tensioning element 12. The legs of the spring 16 are supported axially on this projection 20, so that this also achieves an axial fixing of the spring 16 and thus of the tensioning element 12 relative to the base body 11.
For fixing the roller-shaped joint 17 in the groove-shaped bearing 18, a deflection element 13 is provided. The deflection element 13 is fixed to the base body 11 by means of a snap-fit connection. The deflecting element 13 is clamped on the underside of the base body 11 by means of clamping jaws 21. The other end of the deflection element 13 loops the roll-shaped joint 17 of the tensioning element 12 by means of a clamping element 23. The deflecting element 13 acts as some kind of clamping means which holds the tensioning element 12 on the base body 11. At the same time, in this exemplary embodiment, the deflection element completes the swivel joint for the tensioning element 12, in that it presses the joint head 17 into the bearing 18 in a rotationally movable manner.
By means of the embodiment of the invention shown here, a uniform tensioning of the upper guide apron 7 is achieved. The tensioning element 12 is mounted in a rotationally movable manner and can apply the required pressure to the guide apron 7 without jamming. It is also particularly important that a very stable construction of the base body 11 is ensured. The base body is not weakened by the functional elements (tensioning element 12 and deflection element 13) provided thereon, but is even additionally reinforced in particular by the deflection element 13. The spring 16 takes up only a small amount of space, so that the base body 11 can be designed as solid as possible.
Fig. 2 is a perspective view of one embodiment of the cage 1. The cage 1 has a fastening element 10 and a base body 11 connected in one piece. Of course, these elements may also take embodiments that are separable from each other. As shown, the cage 1 is designed for two guide aprons 7 (not shown here) which run parallel to one another. Accordingly, the cage 1 has two tensioning elements 12 and two deflection elements 13. As shown, each tensioning element 12 is associated with a roller-shaped joint 17, which is rotatably mounted in a groove-shaped bearing 18. Wherein the support 18 is part of the base body 11. In order to hold the roller 17 in the bearing 18 in a rotationally movable manner, the deflecting element 13 loops the roller 17 at both ends of the tensioning element 12 by means of the clamping elements 23. The spring 16 is not shown in the figure and is located between the tension element 12 and the base body 11. After the guide apron 7 has not been placed against the tensioning element 12 and against the deflection element 13, the tensioning element 12 is opened to its maximum position by the spring 16, as shown in the drawing.
As shown, the tensioning element 12 has two delimitation pieces 22. The function of the delimiting piece 22 is: so that the guide apron 7 is guided laterally in the axial direction between said delimitation pieces. Accordingly, the width of the guide apron 7 is approximately equal to the distance a of the two delimitations 22 of the tensioning element 12 (see fig. 3a to 3 c).
As fig. 3a to 3c show, the length of the deflection element 13 and the tensioning element 12 is significantly greater than the distance a between the delimitation pieces 22 between which it is desired to guide the guide apron 7. The length L of the tensioning element 12 is designed in such a way that a different positioning of the delimiting piece 22 is supported. According to the solution shown in fig. 3a, the delimiting piece 22 is located substantially in the centre of the tension element 12. In the embodiment shown in fig. 3b the delimiter 22 is moved to the left, whereas in the embodiment shown in fig. 3c the delimiter is moved to the right.
For example, if the embodiment shown in fig. 3b and 3c is installed in the cage 1, with the embodiment of fig. 3b arranged on the left side and the embodiment of fig. 3c on the right side as seen from the front, this corresponds to a larger distance between the spinning positions, since the distance between the two guide systems for the guide apron 7 is very large. In the case of an exchange of the two tensioning elements 12, the mutual distance is very small, so that this combination can be used for very small spinning position distances. In this way, by using suitable tensioning elements accordingly, the holder 1 can be used in spinning machines with different graduation without having to replace the holder 1 and the deflection element 13.
The roller-shaped joint 17 is also shown in fig. 3a to 3c in dashed lines. It can be seen that the roller-shaped joint 17 projects beyond the tensioning element 12 at both ends thereof and can be engaged and clamped there by the deflection element 13 by means of a clamping element 23. In addition, in the present exemplary embodiment, the clamping element 23 is also used for the central fastening, since the tensioning element 12 is very long. This reliably prevents deformation of the tensioning element 12 during the guidance of the guide apron 7.
In fig. 4a and 4b, different deflection elements 13 are shown. Wherein the deflecting elements 13 have different widths B. This makes it possible to adapt to the specific requirements of the different fiber bundles 6 and to vary the clamping point of the fiber guiding device in the main drawing zone or the distance of the guiding system from the clamping point of the delivery roller pair 2. For this purpose, the entire cage 1 or the tensioning element 12 does not have to be replaced. It is sufficient to embed the matching guide elements 13.
In addition, it is clear from these figures how the deflection element 13 is fastened to the base body 11 or to the joint head 17. These figures each show a catch 21 on the lower end of the deflection element 13, by means of which the deflection element 13 engages with the base body 11 of the cage 1. On the upper end of the deflection element 13, a rounded clamping piece 23 can be seen. The rounding interacts with the roller-shaped joint 17 of the tensioning element 12 and allows a rotational movement of the tensioning element 12 when the joint 17 is fixed in the seat 18 of the base body 11.
Fig. 5 is a cross-sectional view of a substrate 11 containing a fixing element 10. In the fastening element 10, a receiving opening 14 is provided, in which the shaft 3 of the press roller pair can be received. For clamping the cage 1 on the shaft 3, a flange 24 is provided. Wherein the flange 24 of the fixing element 10 can be pressed against the shaft 3 and clamped there by elastic deformation of the material of the fixing element 10.
Fig. 6 is a view of the underside of the cage 1 with the pressure roller 4 and the guide apron 7. The two guide aprons 7 of the press roll pair with the press rolls 4 surround both the respective press roll 4 and the main body 11 containing the deflection element 13. The two press rolls 4 are connected by means of a shaft 3. The shaft 3 has an annular groove 25. The annular groove 25 interacts with the collar 24 of the fastening element 10. The projections 24 and the annular grooves 25 are arranged such that the cage 1 is not only fixed to the shaft 3, but also axially aligned and centered relative to the shaft 3 of the roller pair. This allows a simple and precise positioning of the holder 1 relative to the roller pair.
The invention is not limited to the embodiments shown and described. Variations may be employed which are within the scope of the claims, and features may be combined, even if the features are disclosed and described in different embodiments.
