Description

The present invention relates to a compressor unit for a drafting system of a textile machine. The compressor unit comprises at least one guide and a holder, wherein the at least one guide is arranged on a holder. The at least one guide has a contact surface, which rests on a drafting roller when the compressor unit is brought to the drafting system. A compression region is arranged in and / or on the at least one guide, in particular in and / or on the contact surface, so that a fiber bond guided through the compression region is compressed. In addition, the compressor unit has a receiving element, which has a connection with the holder, and wherein by means of the receiving element, the compressor unit can be received in the drafting system.

From the EP 1 953 275 B1 is a drafting system for warping a fiber structure known. The drafting system comprises mechanical means for compressing the distorted in the drafting fiber structure, which have at least one guide surface, which is arranged in each case obliquely to a transport direction of the fiber structure. In addition, the drafting device has a traversing device, which is coupled to compressor components having the guide surfaces. By means of the traversing device, the life of the drafting rollers can be extended since the fiber structure is displaced by the traversing device over the lateral surface. As a result, a cutting of the fiber structure is prevented at a point of the drafting roller. The disadvantage here, however, is when the traversing mechanism is moved relative to the compressor components during the open drafting system. In order to reconnect the compressor components with the traversing device, a game at the junction between the traversing device and the compressor components is provided. The positioning and oscillation of the compressor components can thus be carried out only inaccurate.

Object of the present invention is therefore to provide a compressor unit with which the leadership of the compressor components can be done accurately and a load of a fiber structure on a drafting roller can be better distributed.

The object is achieved by a compressor unit with the features of the independent claim.

Proposed is a compressor unit for a drafting system of a textile machine comprising at least one guide and a holder, wherein the at least one guide is arranged on the holder. With the guidance of a fiber strand can be performed. In particular, by means of the guide a position of the fiber structure can be changed in the drafting system. The fiber structure can be moved, for example.

Furthermore, the at least one guide on a contact surface, which bears against the operation of the drafting system on a drafting roller. The contact surface is advantageously curved and in particular concave, wherein the contact surface is adapted to a lateral surface of the drafting roller. In this case, for example, a curvature of the contact surface is equal to the curvature of the lateral surface of the drafting roller. As a result, the contact surface lies exactly on the lateral surface, so that preferably no gap is formed between the contact surface and the lateral surface. This prevents, for example, that the fiber structure or individual fibers can slip out of a compression area.

In and / or on the at least one guide, a compression region is arranged. Additionally or alternatively, the compression area can also be arranged in and / or on the contact surface, so that the fiber structure is compressed by the compression area. The compression region may, for example, have the shape of a compression channel. Additionally or alternatively, the compression region may comprise an inclined surface which has an angle, for example between 5 ° and 30 °, to a profile of the fiber structure. The fiber structure is thus deflected when passing through the compression region, for example, on the inclined surface by this angle, wherein the fiber structure is also compressed.

Further, the compressor unit is associated with a receiving element which has a connection with the holder, and wherein by means of the receiving element, the compressor unit can be received in the drafting system. The connection between the receiving element and the holder also serves to position the holder and thus the at least one guide against the drafting system. The receiving element thus connects the compressor unit with the drafting system. In particular, the receiving element store the compressor unit, so that, for example, the at least one guide and its contact surface are arranged to the drafting system and in particular to the drafting roller in the desired position.

According to the invention, the guide and / or the holder and / or the receiving element are mutually displaceable in the axial direction of the drafting roller. For example, so that the connection between the receiving element and the holder is a movable connection. In this case, the holder relative to the receiving element can be moved in an axial direction of the drafting roller. A particular advantage of this is that the holder together with the at least one guide relative to the drafting roller can be moved. As a result, the fiber structure can also be moved by means of the guide, which is arranged on the holder, independently of the drafting system over the lateral surface in the axial direction of the drafting roller. If, however, the guide to the bracket is shifted, the number of moving parts can be minimized.

Alternatively, the complete, consisting of guide, holder and receiving element compressor unit in the axial direction of the drafting roller is displaceable. The compressor unit is arranged on a carrier on the drafting system. This has advantages because the compressor unit is displaced as a whole, and the components of the compressor unit do not have to perform any movements to each other. Therefore, the stability of the compressor unit is increased. In addition, less components are subject to wear, so that the life of the compressor unit is increased.

With a displacement of the guide and / or the holder and / or the receiving element to each other or the entire compressor unit, the fiber structure can be moved over the drafting rollers of the drafting in the axial direction of the drafting roller. A cutting of the fiber structure in the drafting roller is thus delayed, so that the life of the drafting roller is increased.

Another advantage of the invention is that when closing the drafting system, for example, only the holder relative to the receiving element and the drafting system must be moved to adjust the guide to the position of the fiber structure. Additionally or alternatively, the entire compressor unit could be moved relative to the drafting system. When closing the drafting an arm on which the compressor unit is arranged, pivoted down to the drafting roller. The fiber structure lies on the entire length of the drafting roller, so it is not pivoted. In an end phase of closing, the fiber structure must thus be introduced into the guide of the compressor unit. It may happen that the fiber structure and the guide have a different position to each other, the leadership or the fiber strand must be moved so. Since the fiber structure can be guided by means of additional guides of the drafting system in the drafting system, a displacement of the fiber structure is difficult. However, with the invention, the guide can be moved, so that the guide can be adapted to the fiber structure and introduced.

In addition, the compressor unit has an alignment area in order to be able to align the compressor unit with a traversing device. When closing the drafting system, when the arm is placed with the compressor unit on the drafting roller, while a designated element of the traversing device can be introduced into the alignment of the compressor unit. The alignment area thereby aligns with the element of the traversing device, so that the compressor unit is aligned with the traversing device. As a result, the closing of the arm can be simplified and / or automated.

In an advantageous embodiment of the invention, the at least one guide and the holder is integrally formed. This simplifies the manufacture of the compressor unit.

Moreover, it is advantageous if the at least one guide and / or the holder is formed of a wear-resistant material. In this case, the guide and the holder of two different materials or if the guide and the holder is integrally formed may be formed of the same material. The wear-resistant material may be, for example, a plastic, a ceramic and / or a high-strength steel.

Furthermore, it is advantageous if the receiving element comprises a spring element. With the spring element, the holder can be arranged to a certain extent movable in the drafting system. Thus, if necessary, low fit inaccuracies, for example when the lateral surface and the contact surface are not exactly aligned parallel to each other, are compensated.

In an advantageous embodiment of the invention, it is provided that the holder has an elongated recess which is aligned with the axial direction of the drafting roller. The recess may be formed, for example, as an elongated groove. If the receiving element comprises a grip element which engages in the recess, the grip element is displaceably guided guided in the recess. In this case, the grip element, for example, engage positively in the recess. The handle member may also be formed as a bolt which can be moved in the groove. In particular, however, the recess is displaced relative to the receiving element, since the receiving element is attached to the drafting system. With the recess thus the holder is moved with the at least one guide relative to the receiving element and thus with respect to the drafting system.

In an alternative embodiment of the invention, the above-mentioned recess may also be arranged on the carrier. The gripping element of the receiving element then also engages in the recess. As a result, the entire compressor unit relative to the support of the drafting system and so are moved relative to the drafting system. The recess and the handle element have the same features as those just mentioned.

An additional or alternative embodiment of the invention is when adjacent to the recess, an elongated thickening is formed, which is aligned with the axial direction of the drafting roller. In this case, the grip element surrounds the thickening, so that the grip element is displaceable along the thickening. The thickening may for example be formed on an edge between the recess and holder. In addition, the grip element can embrace the thickening in a form-fitting manner. By the displaceability the handle element along the thickening can then be the holder relative to the receiving element and thus moved against the drafting system. An introduction of the fiber structure in the guide is thus facilitated. In addition, the fiber structure can be moved only by means of the holder and the guide in the axial direction of the drafting roller on the lateral surface, which reduces a cutting and increases the life of the drafting roller.

In an alternative embodiment of the invention, the above-mentioned elongated thickening may also be arranged adjacent to a recess of the carrier. The grip element engages around the thickening and can be moved along the thickening. The thickening and the handle element have the same features as those just mentioned. As a result, the entire compressor unit relative to the carrier and thereby against the drafting in the axial direction of the drafting roller can be moved.

Furthermore, it is advantageous if the holder has an alignment region, so that the holder can be aligned and / or displaced relative to the receiving element by means of a displacement element of a traversing device of the drafting system. The traversing device generates a movement in the axial direction of the drafting roller, thus also a movement transversely to the course of the fiber structure. The traversing device is arranged on the drafting system. For this purpose, the traversing device comprises a drive, so that the traversing device can be moved. The movement is transmitted by means of the displacement element, which is designed for example as an arm or bracket, to the holder. The displacement element may for this purpose have a latching element which engages in the alignment region of the holder, in order thereby to transmit the movement of the traversing device to the holder. In the same way, the entire compressor unit, in particular with respect to the carrier, can be displaced by means of the displacement element and the alignment area. This can be shifted over the at least one guide and the fiber strand. The fiber structure is slowly moved by means of the traversing device over the lateral surface, so that it does not cut at one point in the drafting roller. The life of the drafting roller is increased.

In addition or as an alternative, the holder can also be aligned with the latching element by means of the alignment region when closing the drafting system. The alignment region may be formed, for example, as a funnel-shaped notch and the locking element have a conically tapering shape. When, during the closing of the drafting system, the compressor unit and thus the alignment area approach the latching element, the conically tapered latching element slides into the funnel-shaped alignment area. If the locking element and the alignment are not aligned with each other, but have an offset, the alignment is aligned with the locking element. For this purpose, the holder moves relative to the receiving element. Alternatively, the entire compressor unit can be moved relative to the carrier. A displacement of the holder or the compressor unit is easier, since only these must be moved and not the traversing device and the fiber structure.

For this embodiment of the development of the invention, it is advantageous if the displacement element of the traversing device and the alignment of the holder form a detachable connection. In particular, a clearance can be formed between the latching element of the displacement element and the alignment area, so that transmission of vibrations from one component to the other is reduced. In addition, the drafting system can be reopened by the detachable connection, for example, to perform cleaning.

It is also advantageous if the compressor unit has a second guide, which forms a guide pair with the first guide, wherein the two guides are arranged on the holder, that the two guides in the operation of the drafting in the circumferential direction of the drafting roller are spaced from each other , The second guide of the guide pair is arranged in a course of the fiber structure before the first guide. Thus, the fiber structure first passes through the second guide and then the first guide. The second guide can have the same features as the first guide. The second guide may be formed, for example, in one piece with the holder, likewise made of a wear-resistant material, and / or may have a compression region as described above. The second guide is arranged for better positioning and compression of the fiber structure.

An additional development of the invention is when the compressor unit in the axial direction of the drafting roller has a second guide pair, wherein a second fiber strand is guided through the two guides of the second guide pair and compressed by the compression region. Thus, two fiber composites can be passed through the compressor unit and compacted, so that a capacity of the compressor unit is doubled.

FIG. 1 shows a side sectional view of a compressor unit 1 in a part of a drafting system 2. The compressor unit 1 comprises a holder 3 to which a first guide 4 and, in addition to this embodiment, a second guide 5 is arranged. The guides 4, 5 may be formed integrally with the holder 3. Furthermore, the first guide 4 has a first contact surface 6 and the second guide 5 has a second contact surface 7. The two contact surfaces 6, 7 are concave. In particular, the contact surfaces 6, 7 are formed such that they rest against a drafting roller 8. In and / or on the first guide 4 is a first compression region 9 and in and / or on the second guide 5, a second compression region 10 is arranged. Additionally or alternatively, the two compression regions 9, 10 may also be arranged in and / or on the respective contact surfaces 6, 7. The fiber structure 11, which is guided in a running direction LR through the part of the drafting system 2, is also passed through the two compression regions 9, 10 and is compacted in this.

In addition, the compressor unit 1 comprises a receiving element 12 which carries the holder 3 by means of a connection 13. The holder 3 is opposite the receiving element 12 in an axial direction to the drafting roller 8 slidably. Additionally or alternatively, the guides 9, 10 can be moved relative to the holder 3. The receiving element 12 may also include, for example, a spring element, so that the holder 3 can be arranged freely movable relative to the drafting roller 8 to some extent. By means of the spring element so minor fit inaccuracies between the compressor unit 1 and the part of the drafting system 2, in particular the drafting roller 8, are compensated.

The part of the drafting system 2 further comprises a first top roller 14 and a second top roller 15, wherein between these two top rollers 14, 15 and the drafting roller 8, the fiber structure 11 is passed. The drafting roller 8 is driven, so that the fiber structure 11 is pulled in the direction LR by the part of the drafting system 2. The two top rollers 14, 15 are connected to one another by a bridge 16 and are arranged on a carrier 17. On this carrier 17, the compressor unit 1 is also arranged by means of the receiving element 12 and thus to the part of the drafting system 2. In an alternative embodiment, the compressor unit 1 may be displaceable relative to the carrier 17. The carrier 17 is arranged on an arm 18. By means of this arm 18, the carrier 17, the two top rollers 14, 15 and the compressor unit 1 can be pivoted upwards. Remain the drafting roller 8 and the fiber structure 11th

By means of the displacement of the guides 4, 5 relative to the holder 3 and / or the holder 3 relative to the receiving element 12 and / or the guides 4, 5 relative to the receiving element 12, the fiber structure 11 in the axial direction of the drafting roller 8 by means of the compression regions 9, 10th be moved. This is a cutting of the fiber structure 11 in the drafting roller 8 and also in the two top rollers 13, 14 prevented or at least significantly delayed. A life of the rollers is extended so.

FIG. 2 shows a bottom view of an alternative embodiment with a compressor unit 1 and with two guide pairs 19, 20. The guide pair 19 includes the first guide 4a and the second guide 5a. The guide pair 20 includes the first guide 4b and the second guide 5b. The two pairs of guides 19, 20 also have the same effect. With two guide pairs 19, 20, the effectiveness of the compressor unit 1 is increased. Since two pairs of guides 19, 20 are present in this embodiment, in a drafting system 2, a second arrangement of drafting roller 8 and two top rollers 13, 14 must be present.

The fiber structure 11a enters the second guide 5a as a still spreading fiber structure. There it is precompressed in the second compression area 10a. The compression region 10a is formed in this embodiment as a funnel. The pre-compressed fiber structure 11a then enters the compression region 9a of the first guide 4a. There, the fiber structure 11a is further compressed. The compression area 9a has a channel which leads to the running direction LR (cf. FIG. 1 ) of the fiber structure 11a has an angle such that the fiber structure 11a is deflected and compacted on a surface of the channel.

The guides 4a, 5a, 4b, 5b also each have a contact surface 6a, 7a, 6b, 7b, which abut the drafting roller 8 (see. FIG. 1 ).

In the holder 3, a recess 21, for example, a groove arranged. In the recess 21, the receiving element 12 is received, so that the holder 3 relative to the receiving element 12 is displaceable. The holder 3 can thus be moved in a direction of displacement VR1 relative to the receiving element 12. This sliding movement is thus transferred to the fiber composites 11 a, 11 b by means of the guides 4 a, 5 a, 4 b, 5 b and the compression regions 9 a, 10 a, 9 b, 10 b. Thus, the fiber composites 11 a, 11 b are also compared to the drafting roller 8 and the two top rollers 13, 14 moved. A cutting of the fiber composites in the associated rolls is thus reduced, resulting in a longer life of the rolls.

In addition or as an alternative, the guides 4a, 5a, 4b, 5b could also be displaced relative to the holder 3 in a direction of displacement VR2 (for better clarity, a direction of displacement VR2 is indicated only in the guide 4b), which also entails cutting the fiber bands 11a, 11 b reduced in the associated rollers.

FIG. 3 shows a plan view of a compressor unit 1 and a traversing device 22. In addition, only to the essential to the preceding figures 1, 2 essential differences will be discussed. In particular, for example, the compressor unit 1 has the same features and effects as the compressor unit of FIG FIG. 2 on.

The traversing device 22 has a rail 23, whereupon a drive 24 is arranged, which can be moved along the rail 23. On the drive 24, a displacement element 26 is arranged, which has a latching element 27 at the opposite end to the drive 24. The drive 24 can also be located elsewhere and the rail 23, on which a plurality of displacement elements 26 are arranged for a plurality of juxtaposed drafting devices, change. The latching element 27 cooperates with an alignment region 28 of the compressor unit 1, so that when the traversing element 26 oscillates, the displacement of the compressor unit 1 in the direction of displacement VR1 relative to the receiving element 12 takes place. Thus, the fiber composites 11a, 11b are moved in the direction of displacement VR1. This results in the displacement of the fiber composites 11a, 11b in the axial direction of the drafting roller 8 (see. FIG. 1 ). Furthermore the traversing device 22 has an insertion element 25 which introduces the fiber composites 11a, 11b into the compressor unit 1 by means of two insertion funnels 29a, 29b and guides the respective fiber composites 11a, 11b.

The alignment region 28 is arranged in the holder 3 in this exemplary embodiment. Additionally or alternatively, the alignment region 28 could also be arranged in the guides 4a, 5a, 4b, 5b, so that the guides 4a, 5a, 4b, 5b are displaced relative to the holder 3 in the displacement direction VR2 by means of the displacement element 26.

FIG. 4 shows a front view of a section of the holder 3 with an alignment region 28 and a latching element 27 from the FIG. 3 , The latching element 27 preferably engages positively in the alignment region 28, so that a displacement of the displacement element 26 along the rail 23 (see. FIG. 3 ), the displacement of the holder 3 relative to the receiving element 12 (see. FIG. 3 ) causes. As a result, the two second guides 5a, 5b are also displaced with the compression areas 10a, 10b. As a result, in turn, the fiber bundles 11 a, 11 b (cf. FIG. 2) extending through the compaction regions 10 a, 10 b are produced. FIG. 3 ) with shifted.

The alignment region 28 also has two flanks 30 and the latching element 27 and an edge 31. If the compressor unit 1, which can be arranged on a pivotable arm, from above to the drafting roller 8 (see. FIG. 1 ), an offset of the alignment region 28 with respect to the displacement element 26 can be compensated for by means of the flanks 30 and the edge 31. The edge 31 slips off on the flanks 30, so that the latching element 27 is centered in the alignment region 28. In this case, the holder 3 is moved relative to the receiving element 12 and the traversing device 22. The receiving element 12 and the traversing device 22 advantageously remain opposite the drafting system 2 in their position. By moving the holder 3 in this alignment process the fiber composites 11a, 11b are co-displaced, so that they change their position on the drafting roller 8 in the alignment process. A cutting is thus reduced.

FIG. 5 shows a side sectional view through a holder 3 with a receiving element 12. In the holder 3, the recess 21 is arranged, in which a grip element 32 of the receiving element 12 engages. The gripping element 32 has an upper stop 33 and a lower stop 34, which surround the recess 21 such that the receiving element 12 is displaceable exclusively along the recess 21.

Additionally or alternatively, the recess 21 could also be arranged in the carrier 17 and the gripping element 32 at the other end of the receiving element 12. As a result, the receiving element 12 and thus the entire compressor unit 1 relative to the carrier 17 can be moved.

FIG. 6 shows a side sectional view of an alternative to the handle member 32 and a thickening 35. The handle member 32 encloses a thickening 35 in this embodiment form fit. The receiving element 12 can be moved again only along the thickening 35 in the direction of displacement VR1. In addition, the receiving element 12 can be pivoted to the holder 3 to a certain extent, so that an orientation of the compressor unit 1 is variable. As a result, the compressor unit 1 can be better adapted to the drafting roller.

Additionally or alternatively, the thickening 35 with the recess 21 could also be arranged in and / or on the carrier 17, and the gripping element 32 at the other end of the receiving element 12. As a result, the receiving element 12 and thus the compressor unit relative to the carrier 17 can be moved.

FIG. 7 shows a further alternative embodiment of the handle member 32 and a shaft 36. The receiving element 12 has at one end a bore 37 which surrounds the shaft 36. As a result, the receiving element 12 is displaceable exclusively in the direction of displacement VR1. In addition, the receiving element 12 can be pivoted to the holder 3, so that an orientation of the compressor unit 1 is variable. As a result, the compressor unit 1 can be better adapted to the drafting roller.

Additionally or alternatively, the shaft 36 could also be arranged on the carrier 17 and the bore 37 at the other end of the receiving element 12. As a result, the receiving element 12 can be moved relative to the carrier 17.

The present invention is not limited to the illustrated and described embodiments. Variations within the scope of the claims are also possible as a combination of features, even if they are shown and described in different embodiments.
