Description

The present invention relates to a turntable for a sliver storage device of a sliver-producing or -processing spinning preparation machine according to the preamble of claim 1 and to a method for depositing a continuously fed sliver into a container according to the preamble of claim 18.

From DE 41 31 134 a turntable with a spatially curved band channel is known, wherein the band channel is formed from a piece of pipe with two directly merging circular arcs. The disadvantage here is that occasionally accumulate from the sliver dissolved particles on the inner wall of the band channel.

These particle accumulations show the tendency to increase during operation of the tape storage to a certain size, and then detach themselves as a closed particle composites of the inner wall. This detachment often occurs when the sliver receiving container is changed. As a rule, the particle groups (so-called mice) fall into the container and so pollute the deposited sliver. This can lead to problems in the further processing of the sliver.

Particle deposits on the inner wall of the band channel can additionally cause damage to the sliver to be deposited, in particular at high and highest deposition rates. The particle deposits For example, they can lead to a feed distortion in the sliver or to a deterioration of the degree of parallelization of the fibers.

Furthermore, it is disadvantageous that in operation in the turntable shown a high longitudinal tension in the sliver is required to pull the sliver through the band channel. This creates an undesirable tension distortion, which degrades the quality of the deposited sliver.

Object of the present invention is to provide a turntable and a method which overcomes the disadvantages mentioned and in particular at high and highest speeds (especially above 1000 m / min) ensures a safe and gentle storage of a high-quality sliver.

The object is achieved by a turntable and a method having the features of the independent claims.

Sliver usually includes particles which are only incompletely integrated into the inner structure of the sliver. Such particles are, for example, short fibers and dirt particles. Under the influence of the forces acting on the sliver in the band channel forces, a part of these particles from the structure of the sliver dissolves and the dissolved particles are transported only in loose connection to the sliver. The reduction of the total forces acting according to the invention counteracts the unwanted release of particles from the sliver.

According to the turntable for this purpose has a band channel, which has at least a predominant part or much of its length such a shape, the predetermined ratio between the feed rate the sliver and the rotational speed of the turntable along the band channel substantially no tangential with respect to the axis of rotation of the turntable, acting on the sliver to be deposited force occurs. The movement of a single element of the sliver results from the vectorial addition of the rotational movement of the band channel and the movement of the individual element of the sliver relative to the band channel, the direction of which in turn depends on the shape of the band channel according to the invention.

Furthermore, the attachment of detached from the sliver particles on the inner wall of the band channel is prevented. In the turntable according to the invention, the normal force between these loosely entrained particles and the inner wall of the band channel - and thus the frictional force - reduced and preferably minimized. This ensures that the particles transporting through the belt channel forces, in particular the centrifugal forces caused by the rotation of the turntable and the friction between the running sliver and the particles are greater than the particles braking forces, namely the friction forces between particles and the interior wall. As a result, so the interfering particles are removed individually and continuously from the band channel and not as in conventional devices as closed particle networks.

Achieving the advantages of the invention is not tied to a specific speed of the turntable nor to a certain feed speed of the sliver. It is only essential that the ratio of these two parameters and the shape of the band channel is coordinated. If the tape storage is designed so that the ratio between the feed rate of the sliver and speed of the turntable with a change in the feed rate, so for example when starting the tape storage from standstill, is constant, so regardless of the feed rate the sliver ensured by the tape channel according to the invention a substantially tangential force-free tape storage.

The inventive design of the band channel ensures that the total force acting on the sliver total force is greatly reduced, since the total force results in this case only by the addition of radial and axial forces.

Although it is desirable that the band channel is formed on the entire length in accordance with the invention, it is not contrary to the invention, if in certain areas, for example at the inlet or outlet to take account of the local special conditions, a deviation from the Ideal shape is desired.

The invention causes a reduction of the Antagems released from the sliver particles regardless of the coefficient of friction between the inner wall of the band channel and the respective particles. This concerns both single fibers extracted from the sliver and dirt particles released from the sliver. It is only decisive that the invention reduces the normal force between the particles and the inner wall of the band channel due to the substantial elimination of said tangential forces.

In addition, the strip channel formed according to the invention ensures gentle strip placement. Due to the lower loading of the sliver with forces the risk of incorrect distortion is reduced. Furthermore, the leaching of particles from the sliver is minimized.

In one embodiment of the invention, the band channel is formed such that the center line of the band channel is approximated or nestled at least over a majority or most of its length to an ideal line, which runs along the entire length of the band channel such that at a predetermined ratio between the speed of the turntable and the feeding speed of the sliver, the tangential velocity of each point of the ideal line resulting from the rotation of the turntable relative to the textile machine is equal to and equal to the tangential component of the relative velocity of the sliver opposite the band channel at the point in question due to the transport of the sliver along the center line in the band channel Ideal line is. The center line coincides with a band channel of circular cross-section and uniform wall thickness with the centroid of the band channel.

As a rule, the ratio between the feed rate of the sliver and the rotational speed of the turntable and the storage radius and the extent of the channel is parallel to the axis of rotation of the turntable (height) predetermined. Also, the desired exit direction of the sliver is known from the turntable. In this case, an ideal line can be calculated by numerical methods, which represent a complex tortuous space curve.

If the band channel is formed so that the center line of the band channel essentially corresponds to this ideal line, the transport of the sliver takes place substantially without tangential force.

An absolutely tangential force-free storage is not possible, however, since the cross-section of the sliver has a two-dimensional extent. The actual transport path of a single element of the fiber sliver lying in the sliver therefore necessarily deviates from the ideal line. The deviation However, in the usual, relatively thin slivers is low.

Furthermore, the line of movement, ie the line which actually passes through the center or center of gravity of a sliver cross-section during its movement in the band channel, may deviate from the center line of the band channel in sections of the band channel. However, the tangential forces remaining due to the deviation of the line of movement from the centerline are small.

It is also possible that the band channel is shaped so that the actual line of movement of the sliver substantially corresponds to this ideal line. However, this presupposes that the movement line is determined in advance, for example by means of a computer simulation. The centerline of the band channel and the actual line of movement may coincide, which, assuming or calculated, will benefit a lighter band channel shaping in accordance with the present invention.

It is particularly advantageous if the center line of the band channel is composed of successive curve sections in space, each curve section consists of an elementary geometric shape. Suitable geometric shapes are, for example, helical sections, circular arcs, elliptical arcs or straight line sections. Such a belt channel is relatively easy to produce with today's machines, without the functionality according to the invention, namely the leadership of the sliver substantially along the ideal line without significant tangential component of a single element of the sliver, is affected relevant.

If the curve portion carrying the input opening is a straight line section, the axial extent of the turntable, that is to say the overall height, can be simpler Be adapted to the respective Erforderemisse which are determined by the geometry of the sliver storage device, adapted. For this purpose, only the length of the straight section must be changed. The geometry of the complex curved and / or tortuous curve section can remain unchanged.

In a particularly preferred embodiment, the curve sections consist exclusively of plane geometric shapes. Level shapes are all shapes that can be displayed in one level.

It is particularly advantageous if the curve sections merge without kinking at the transition points. In other words, the curve sections at the transition points on a common tangent.

In a particularly simple manner, a turntable according to the invention can be produced if the center line preferably has three to twelve and particularly preferably four to eight immediately consecutive curve sections, which are each circular arcs, wherein adjacent circular arcs have different radii and / or lie in different planes.

Furthermore, it is advantageous if the center line in the plan view at the upstream opening portion of the outlet opening with respect to the axis of rotation of the turntable has an outwardly facing radial component. This ensures that particles released from the sliver are accelerated outwards by the radial forces upon reaching the exit opening and are carried away in this way.

The removal of particles released from the sliver is also promoted if all the tangents from that section of the center line, which extends in plan view over the opening area of the outlet opening, with the pressing surface at an angle of less than 45 °, preferably less than 30 ° include. Here, the center line intersects the pressing surface at an acute angle, whereby the outlet opening of the band channel takes the form of an elongated kidney.

Particularly preferred - which also constitutes an independent aspect of the invention - is the opening area of the exit opening in the bottom view is larger than the rest, visible in the bottom view surface of the band channel. Advantageously, said opening area is approximately twice as large or larger compared to said closed area. The kidney shape of the outlet opening is considerably more pronounced in these embodiments compared to the known band channels. In the known band channels, said opening area of the outlet opening is always smaller than the remaining area of the band channel, which is visible in plan view.

With the previous Efindungsaspekt contiguous, but also to be regarded as an independent Erfndungsaspekt, the opening angle β of the output opening of the band channel - seen from the bottom of the turntable - more than 45 °, and preferably more than 60 °. Even larger opening angles with 80 ° or 90 ° or even larger are possible.

If the center line seen in the transport direction with respect to a normal plane of the rotation axis of the turntable has a monotonous, preferably a strictly monotone decreasing slope, the current sliver is deflected particularly gently.

Furthermore, a gentle storage is effected when the center line of the band channel seen in the direction of transport increases monotonically, preferably one strictly monotonically increasing distance from the axis of rotation of the turntable has. This ensures that at least one component of the centrifugal force acting on the particles has parallel to the transport direction and thus causes or at least supports the transport of the particles.

The strip channel according to the invention can in principle have a constant or a varying cross-section in the longitudinal course. However, a constant cross section is preferred. The shape of the cross section is not essential to the invention. In particular, round cross sections are preferred. Even oval cross sections can be advantageous.

The band channel according to the invention may be formed in one or more parts. In a multi-part and in particular two-part design, for example, the mouth of the band channel, which opens with the exit opening in the plane of the pressing surface, formed as a separate part and integrated into the underside of the turntable, e.g. be poured, while the remaining, much longer part of the band channel is formed in one piece and is hidden with the mouthpiece.

In the method according to the invention, the deflection of the sliver takes place in the band channel such that substantially no tangential forces are exerted on the sliver relative to the axis of rotation of the turntable and thereby minimizes the band channel acting on the sliver frictional forces, wherein the longitudinal tension is chosen so that the remaining friction forces are barely overcome. The longitudinal stress is therefore chosen sufficiently low in order to avoid a tension distortion as possible. The longitudinal tension can be generated by mechanical or pneumatic means, but it is preferred that - as known from the prior art - pressed the sliver by means of the pressing surface on already deposited sliver is pulled out of the band channel by the contact with the deposited sliver. In this case, the rotation of the turntable relative to the sliver container is utilized in a simple manner.

The longitudinal tension can in this case be selected by setting the pressing force, which acts on the emerging from the output port sliver, and / or by adjusting the relative speed of the sliver, which emerges from the outlet opening to the container. The pressing force can be regulated for example in raised from outside the container container trays by different Absenkwege the container bottom during filling.

It is particularly favorable if the longitudinal tension is selected so that the tension distortion of the sliver produced by the longitudinal tension is less than 1.02, preferably less than 1.01.

Advantageous developments of the invention are characterized by the features of the subclaims.

the band channel according to Figures 2 and 3 from different perspectives.

The known turntable 1 according to the figure 1 comprises a plate body 13, a plate holder 3 and a spatially curved band channel 2 with a center line 14. The band channel 2 is by means of a casting compound 4 at its upper end on the turntable holder 3 and at its lower end with a casting compound 8 fixed to the plate body 13. The plate body 13 has at its lower end a pressing surface 7. The turntable 1 rotates in operation about its axis 11. For this purpose, the turntable 1 is mounted and driven by means not shown.

Sliver occurs parallel to the axis of rotation 11 in the region of the inlet opening 5 in the band channel 2, is deflected here and leaves the band channel for storage in a container 10 through the output port 6, which lies in the plane of the pressing surface 7. The distance 9 between pressing surface 7 and container 10 is selected to be low, so that stored sliver can not out of the container 10 out.

The band channel 2 consists of two directly merging circular arcs 15, 16, which are arranged in different planes. A passing element of the sliver is exposed in the region of the circular arc 15 strong tangential forces (tangential with respect to the axis of rotation 11). As a result, the sliver is heavily stressed, and the release of particles from the sliver is favored. These liberated particles tend to preferentially accumulate in the circular arc 16 in the region of the outlet opening on the inner wall of the band channel 2. These deposits can form a particle lump of considerable size during operation of the tape storage (so-called mice). From time to time, such lumps of particles detach from the inner wall of the band channel and can then enter the sliver container, which is problematic in the further processing of the sliver. These accumulated particles can continue to damage the fiber sliver performed.

The turntable 1 according to the invention differs from the turntable 1 shown in FIG. 1 by a specially shaped band channel 2.

Figures 2, 3, 5-13 show a band channel 2 for a turntable 1 according to the invention, the center line 14 is composed of five consecutive circular arcs B1-B5. Neighboring circular arcs are each kinked into each other, i. they have a common tangent at their points of contact. The circular arcs B1-B5 are shown as dotted lines. The band channel 2 is shaped such that the center line 14, which consists of the circular arcs B1-B5, to an ideal line 12, which is shown in phantom, approximated or snuggled. The center line 14 is in the region of the inlet opening 5 congruent with the axis of rotation 11 of the turntable. In the region of the outlet opening 6, the center line 14 has a low pitch. The center line 14 thus passes at an acute angle through the exit opening.

The removal of particles released from the sliver (in the case of particle accumulations, these are the so-called mice) is also conveyed when all the tangents ML from the section of the center line which extends in plan view over the opening region of the exit opening 6 with the pressing surface an angle of less than 45 °, preferably less than 30 °. The tangents ML1 and ML2 which intersect the plane of the pressing surface 7 at the angles α1 and α2 are shown by way of example.

With respect to a normal plane to the axis of rotation 11 of the turntable, the center line 14 in the region of the inlet opening 5 to an infinite pitch, which seen in the transport direction decreases steadily to the exit opening 6.

FIG. 3 shows the band channel 2 according to the invention in a plan view. It has a circular cross-section, which is constant in the course of the band channel 2. The exit opening 6, which lies in the plane of the drawing, has the shape of a long kidney. The radial distance of the center line 14 from the axis of rotation 11 increases steadily from the entrance opening to the end of the fourth arc B4. In the area of the arc B5, this distance does not change substantially.

At the upstream opening portion 6a of the kidney-shaped exit opening 6, the tangents ML of the center line 14 have a radial component ML _rad relative to the rotation axis 11 of the turntable 1 (see FIG. As a result, particles located in the band channel 2 are accelerated out of the band channel by the radial forces. The upstream opening portion 6a of the exit port 6 is that portion which is first passed by an element of the conveyed sliver and lies before the passage of the center line 14 through the plane of the pressing surface 7.

It can also be seen from FIG. 3 that the kidney-shaped opening area of the outlet opening 6 in plan view is larger than the remaining closed area of the band channel 2, which is also seen in plan view. In the illustrated embodiment, the opening area of the outlet opening is approximately twice relative to the plan view as big as the closed area.

It is also apparent from FIG. 3 that the opening angle β of the outlet opening 6 in the present case is greater than 90 °.

Figure 4 shows a section of the band channel 2, which rotates in the arrow direction about the axis of rotation 11 of the turntable 1. A point P, which lies on the ideal line 12, has a tangential movement with the velocity vector V _{BK-TM tang} because of the rotation of the turntable 1. An element E of the sliver located at the point P is moved relative to the sliver channel 2 with the velocity vector V _FB-BK . This velocity vector V _FB-BK can be broken down into a tangential component V _{FB-BK tang,} a radial component V _{FB-BK rad} and an axial component V _{FB-BK ax} .

The shape of the band channel 2 shown in FIGS. 2, 3, 5-13 is selected such that the tangential component V _{FB-BK tang of} the element E of the sliver is the same as the movement of the point P relative to the textile machine V _{BK-TM tang} , This condition applies at least approximately to each point P lying on the centerline 14 of the band channel.

As a result, an element E of the sliver passing through the channel 2 is not subjected to any significant tangential velocity or acceleration. Thus, no significant tangential forces act on an element E of the sliver. The resulting movement V _{FB-TM of} an element E of the sliver substantially comprises only a radial component V _{FB-TM rad} and an axial component V _{FB-TM ax} . The addition of said components gives the velocity vector V _FB-TM of element E at point P.

Compared to the textile machine so moves an element E radially and straight away from the axis of rotation 11 of the turntable 1 away. The ideal line 12 can be included numerically calculated given geometric dimensions. The ideal line 12 extends in this case over the entire length of the belt channel 2 such that at a predetermined ratio between the feed speed of the sliver and the rotational speed of the turntable 1, the resulting by the rotation of the turntable relative to the textile machine tangential velocity V _{BK-TM tang} every point P of the ideal line 12th opposite equal size of the tangential component V _{FB-BK tang} resulting from the transport of the sliver in the band channel _tang the relative speed of the sliver relative to the band channel at the relevant point P of the ideal line. The band channel can then be shaped such that the center line 14 of the band channel 2 is substantially identical to the ideal line 12 or conforms to it. Assuming that the centroid line of the sliver moves substantially along the centerline 14 through the sliver channel 2, the sliver experiences only minor or negligible tangential forces, despite its cross-sectional expansion.

FIG. 5 shows the band channel 2 according to the invention in the plane E1 of the first circular arc B1. The circular arc B1, which in this area represents the center line 14 of the band channel, has a radius R1 and extends over an angle W1. R1 and W1 are chosen so that the sheet B1 is approximated to the ideal line 12, not shown for reasons of clarity or conforms to this. The arc B1 and the subsequent arc B2 have a common tangent T1,2 at their transition point.

FIG. 6 shows that the planes E1 of the first circular arc B1 and E2 of the second circular arc B2 are inclined relative to one another by an angle W1, 2.

Figure 7 shows the plane 2 of the circular arc B2 of the center line 14 of the band channel 2. The arc B2 has a radius R2 and extends over an angle W2. The arc B2 and the subsequent arc B3 have at their point of contact the common tangent T2, 3.

According to FIG. 8, the planes E2 of the arc B2 and the plane E3 of the arc B3 are inclined relative to each other by the angle W2,3.

Figures 9 and 10 show the bow B3 and the transition to the bow B4.

Figures 11 and 12 show the bow B4 and its transition to the bow B5.

Finally, Figure 13 shows the bow B5. In the exemplary embodiment according to FIGS. 5-13, all radii R1 to R5, arc angles W1 to W5 and inclination angles W1,2, W2,3, W3,4, and W4,5 are selected so that the center line 14 as a whole approximates the ideal line 12 is or conforms to these.

The band channel 2 according to FIGS. 2, 3, 5-13 can be produced in a simple manner by means of a free-form bending machine from a previously cylindrical tube.

The present invention is not limited to the illustrated and described turntable. There are modifications within the scope of the claims at any time. For example, it can be provided that the band channel 2 has a different number of circular arcs from the embodiment shown. Advantageously, this number is four to eight circular arcs, since in such a number both a simple manufacturability and a good approximation of the center line is guaranteed to the ideal line. The invention can also be used both in round cans, which are rotated during filling, as well as rectangular cans, which are placed during the filling in translational motion apply.
