Technical field
The present invention relates to a kind of top cradle that is used for the drafting system of fine spining machine, described top cradle have at least one be applied in spring force, tension upper leather ring and at the apron guiding element that turns to edge that this upper leather ring is turned to, this apron guiding element remains on the middleware of described top cradle.
Background technology
Utility model patent document DE 92 14 598 U1 of Germany disclose a kind of claim 1 top cradle as described in the preamble, the apron guiding element that this top cradle has a tension upper leather ring and this upper leather ring is turned to, described apron guiding element remains on the middleware of described top cradle.This apron guiding element has been applied in spring force, so that keep described upper leather ring with the tension force that limits.In order to guide described apron guiding element, described apron guiding element has the shaping axle journal, and described axle journal is directed in the respective channel that forms on described middleware.According to DE 92 14 598 U1, described axle journal and described passage are arranged in the operating path width of described upper leather ring on cradle or middleware.At this moment, the channel depth in the described middleware is confined at this locational middleware width.
The shortcoming of disclosed top cradle is in the prior art, on the apron guiding element with respect to the horizontal plane the rising that turns to the edge and the amplitude of descending motion than the axle journal of guiding usefulness and passage between with to make relevant play amplitude big.The reason of this situation is that with respect to the passage on the middleware of top cradle, the apron guiding element can protrude setting.When making the upper leather ring motion of straining by the apron guiding element, the height change at edge always appears turning to subsequently; And when making top cradle static, turn to the height at edge to change inversely.With duty relatively, the tractive force that occurs in the upper leather ring points to different directions.This result who causes is, in described upper leather ring operating period, the edge that turns to of described apron guiding element is upwards drawn, and during inactive state, the edge that turns to of described upper leather ring deflects down.Yet the lower limb of described apron guiding element is a procedure parameter with respect to the deflected height of following apron bridge shape frame or following apron, and this procedure parameter has influenced the result of spinning process subsequently effectively, therefore knows that the height of deflection has very big meaning.Turn to the edge to be so positioned, promptly described upper leather ring and described down apron operation parallel to each other and change their height, variation of this height are to be difficult to or can not to determine fully during operation.
Summary of the invention
Therefore, task of the present invention provides a kind of top cradle, and the characteristics of this top cradle are: turn to the changes in deflection at edge especially to turn to the changes in deflection at edge very little when changing the duty of upper leather ring.
According to the present invention, this task realizes by the characteristic of claim 1.
Favourable improvement of the present invention is the theme of dependent claims.
According to the first aspect suggestion, at least one pair of is set on the apron guiding element outside the operating path width of upper leather ring and on the middleware is used to guide the apron guiding element, mutual corresponding induction element.The main advantage of this layout is, with respect to according to the layout of prior art (induction element be arranged on the following of apron guiding element and and in its operating path width), is used to guide the induction element of this apron guiding element can be configured to phenomenal growth.By this measure, with respect to top cradle of the prior art, length of lead of the present invention is obviously elongated, turns to the rising at edge and the size of descending motion to be reduced thus, this size is reduced to the play size of the induction element of guiding usefulness, and this play size is known and relevant with performance.As describing in detail for prior art in the above, by this layout avoided fully basically since duty change cause turn to edge deflection.By reducing advantageously to have influenced the result of the result of drafting process and spinning process subsequently because of the upper leather ring duty changes the size that turns to edge deflection that causes.
For this reason, at least one induction element on described middleware can be configured to guide groove, simultaneously at least one induction element on the apron guiding element be configured to guide rail.
Here, described guide groove or described guide rail are constructed to continuous.
Alternatively, the induction element that is constructed at least one guide groove can have discontinuities (Unterbrechung).
Similarly, the induction element that is constructed at least one guide rail can have discontinuities.
So be chosen in the scope of the discontinuities that is provided with in the horizontal plane of described guide rail and/or described guide groove, that is, it is overlapping at least in part that the nothing of described guide groove and described guide rail is interrupted section.
Therefore, on at least one guide groove and/or at least one guide rail, should so select the layout of described discontinuities, promptly, with the location independent of apron guiding element with respect to middleware, always there is engagement in all sections of the guide rail that is disconnected at least in part with their respective segments on the guide groove that is disconnected, thereby have avoided owing to duty changes the described deflection that turns to the edge that causes.
In preferred improvement project, described guide groove can extend beyond the length range of described apron guiding element in its horizontal plane, yet is subjected to the possible constructions spatial constraints.This has further advantageously influenced the described size decreases that turns to the rising and the descending motion at edge.
Especially described guide groove can extend to the edge that turns to of apron guiding element.Thus, can reduce the protrusion amount that described apron guiding element exceeds described guide groove.Correspondingly attainablely be that when described guide groove extends beyond describedly when turning to the edge on deviating from of described apron guiding element turns to the side at edge, described protrusion is reduced.
In a favourable embodiment, the apron guiding element can be configured to all have in two sides guide rail, and described middleware is configured to have corresponding guide groove.The advantage of this make is: the above apron guiding element can be designed to identically in two sides, and this not only all produces favorable influence to the manufacturing cost of the member that preferably is embodied as injection molding member but also to the installation of top cradle.
Advantageously, the length of described two guide grooves can be different.This make of middleware has been simplified the installation and removal of upper leather ring.
At this, in two guide grooves on the short outward flange that should be arranged on described middleware, so that can more easily mount and dismount described upper leather ring.

The specific embodiment
View among Fig. 1 shows top cradle 1, and this top cradle 1 comprises a middleware 2 and two apron guiding elements 3.Middleware 2 is installed on the axle 5 of two top rollers 6.Two top rollers 6 remain on the guide rod of top roller carrying and arm in known manner.Apron guiding element 3 is relevant with the top roller 6 of two rotatable arrangements.
Unshowned upper leather ring is around top roller 6 and apron guiding element 3.At this, by the described upper leather ring of apron guiding element 3 guiding, and this upper leather ring is turning to edge to turn to.By the operating path width of the next door 4 restriction apron guiding elements 3 that are provided with perpendicular to the upper leather ring direction of motion on the apron guiding element 3,, can avoid described upper leather ring thus from 3 slippages of apron guiding element as obviously finding out from Fig. 1 to Fig. 3.In order to strain described upper leather ring, apron guiding element 3 has been applied in spring force, produces this spring force by the spring 7 that is arranged between middleware 2 and each apron guiding element 3.As shown in Figure 3, spring 7 is arranged in each interconnective circular channel 8,9 of middleware 2 and apron guiding element 3, so that protection spring 7 is to avoid contacting fibre fluff.
In order to guide apron guiding element 3, forming induction element on the middleware 2 and outside the operating path width at described upper leather ring.In the embodiment shown, described induction element is constructed to guide groove 11 and the guide rail 12 outside upper leather ring operating path width.Guide groove 11 is used to be contained in the corresponding guide rail 12 that forms on the apron guiding element 3.In addition, on the apron guiding element 3 in the operating path width axle journal 13 is set, axle journal 13 has engaging protrusion 14 at its free terminal.Axle journal 13 is engaged on the passage 15 of the correspondence of the operating path width that is positioned at upper leather ring equally.The engaging protrusion 14 of described apron guiding element 3 its position that is mounted to middleware 2 in the back with passage 15 in the recess engagement.By this way, avoided when removing upper leather ring, apron guiding element 3 comes off from the mid portion 2 of top cradle 1.
Find out obviously that as the view from Fig. 2 middleware 2 has in the zone that is provided with each apron guiding element 3 than the little horizontal-extending portion in the zone in the middle of it, it is used for fixing on the axle 5 of two top rollers 6.Cause the reason of this situation to be, in traditional top cradle 1, be used to guide the axle journal 13 and the corresponding passage 15 of apron guiding element 3 being restricted aspect their length, this is because described axle journal 13 and passage 15 are arranged in the upper leather ring operating path width on apron guiding element 3 or the middleware 2.
By guide groove 11 and the corresponding guide rail 12 arranged outside the operating path width of upper leather ring according to the present invention, it is longer according to the passage 15 in upper leather ring operating path width and the axle journal 13 of prior art that guide groove 11 and corresponding guide rail 12 can be implemented as beguine.In addition, obviously illustrate as Fig. 3, the front end of guide rail 12 extends in the next-door neighbour's who turns to edge 16 the zone of apron guiding element 3, so the protrusion amount that apron guiding element 3 exceeds guide rail 11 reduces.By these measures, apron guiding element 3 turn to edge 16 may rise and the size of descending motion still only is in the order of magnitude of the play amplitude that the running of induction element causes.Thus, avoided basically make upper leather ring when motion or when making upper leather ring static because the deflection that turns to edge 16 that the tractive force that the duty change produces causes, this tractive force points to different directions with duty relevantly.
According to available structure space, the guide groove 11 that can prolong middleware 2 makes it to exceed to turn to edge 16 or surpass and deviates from a side that turns to edge 16.
Illustrated among Fig. 4 top cradle 1 ' the vertical view of embodiment of modification, and vertical view according to the apron guiding element of second embodiment of Fig. 4 has been shown among Fig. 5.As obviously finding out from Fig. 4 and Fig. 5, in this embodiment, described induction element be middleware 2 ' on guide groove 11 ' form and being deviate from apron guiding element 3 ' a side that turns to edge 16 on guide rail 12 ' form, this induction element is lengthened out.Its advantage is, optimization utilize top cradle 1 ' the situation in available rear structure space under, since prolonged the induction element 11 that exceeds middleware 2 ' width ', 12 ', therefore when changing duty, surpass induction element 11 ', 12 ' between the apron guiding element 3 ' deflection of play amplitude can be reduced.
In addition, the apron guiding element 3 according to the 3rd embodiment has been shown among Fig. 6 " perspective view, this apron guiding element 3 " guide rail 12 " is interrupted by groove 10 at least one position.Here the guide rail 12 that illustrates " the interruption implementation cause in guide groove 11 forming 2 supportings; and this is a kind of trickle modification; this modification has guaranteed same stability, as according to the continuous guide rail 12,12 of having of Fig. 1 to Fig. 5 ' apron guiding element 3,3 ' scheme.Similarly, guide groove and/or guide rail also can have at least one discontinuities or groove 10.Here the interruption of guide groove can be the material groove, and this material groove does not hinder continuous guide rail 12,12 ' and guide rail 12 " the smooth locomotivity in the horizontal plane of interrupted guide groove of being interrupted by groove 10.
According to the top cradle 1 that shows according to Fig. 1 " Fig. 7 of the 4th embodiment, middleware 2 ' have guide groove 11 ', by groove 18 piecewises of in horizontal plane, extending interrupt this guide groove 11 '.In this flexible program, the continuous guide rail 12 of apron guiding element 3 similarly only be bearing in guide groove 11 ' the section that interrupts of nothing on two positions on.
At last, also can consider the combination of two kinds of flexible programs, in this combination, not only described guide rail but also described guide groove have the discontinuities that is form of grooves.
During operation and when changing duty, according to the apron guiding element of the 3rd or the 4th embodiment or according to the apron guiding element of these two embodiments and the combination of middleware, precondition for apron guiding element stability is: always there is contact each other in induction element, so that avoid the apron guiding element to horizontal plane deflection.
