INT CL 3 D 02 J 3/18 Index at acceptance DIF 34 L ( 72) Inventor ANDRE LATTION ( 54) AN APPARATUS FOR WAXING YARN ( 71) We, MASCHINENFAB 3 RIK RIETER A G, a body corporate organised under the laws of Switzerland, of Winterthur, Switzerland, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:-
The present invention concerns an apparatus for waxing yarn using solid wax on an open-end spinning machine the apparatus having a substantially cylindrically shaped wax body arranged to be axially movable on a guide pin.
A waxing device of this kind is already known In this known device, a wax body is loosely rotatable on an inclined guide pin and a yarn which has been pretensioned by two nip points contacts the front of the wax body which is roll-shaped and has a central hole The wax body is loosely slidable over the whole length of the guide pin for levelling out differences in the yarn path length caused by the yarn traversing motion Owing to the inclination of the pin, the wax body can slide freely along the guide pin until it reaches a stop.
However, in operation its sliding path is limited by the yarn passing through Thus, the yarn is deflected from its straight path between the two nip points, which can, for example, be formed by yarn take-off rolls on one hand and by the winding rolls of an open-end spinning unit on the other hand.
The deflection angle depends on the yarn tension, the weight of the wax body and on the friction between the wax body and the guide pin This tension device has a number of substantial disadvantages.
One of these disadvantages is that it is not possible to ensure a constant degree of yarn waxing as the deflection of the yarn by the wax body at constant yarn tension is also, among other influences, influenced in function of the changing weight of the wax body: the contact force of the yarn on the wax body is therefore not constant.
However, this contact force determines the quantities of wax taken up by the yarn, i e.
as the wax body wears off and diminishes in weight, the wax take-up of the yarn continually diminishes during operation.
Variations of the friction between the wax body and the guide pin also result in changes of the contact force A further disadvantage is that the yarn is waxed in a one-sided contact as it passes through freely.
Furthermore, this known device has the very important disadvantage that if used, for example, it is used on an open-end spinning machine, the wax body interferes with the yarn path as the yarn spinning process is started, e g after an end breakage The operator thus is forced during the spinning start-up operation, which in itself is a very delicate operation requiring the full ability and attention of the operator, also to take care of the wax body in such a manner that the wax body does not impair the spinning start-up operation Thus the spinning startup process is rendered more difficult and the source of disturbances is augmented.
The danger also exists that, due to faulty manipulations by the operator, the yarn is not guided into its proper position along the wax body after the spinning start-up process, which again causes irregularities in the waxing process.
In another known waxing device a wax body, which also is of cylindrical shape, is rotatably supported on a guide pin, the axis of which is at right angles with respect to the yarn distribution plane The axial position of the wax body is determined by a stop The stop is adjustable with respect to a guide rod for the yarn which is arranged above the end face of the wax body and is parallel to the axis of the grooved drum of the yarn winding device.
This known device permits the wax takeup rate of the yarn to be maintained constant independently of the weight of the wax body, because the wax body resting against the stop is to be considered as a O ( 11) 1 565 282 1,565,282 fixed body the weight of which is supported not by the yarn but by the free stop.
However, this known device also has substantial disadvantages In this known device also, just as in the known device previously mentioned, the wax body in use on an open-end spinning machine interferes with the yarn path and thus requires additional attention of the operator in such manner that the yarn started up is brought into contact with the end face and not with the cylindrical side of the wax body.
Furthermore, a further disadvantage of this device is that deactivation of the waxing device is relatively complicated, as dismantling of the wax body is required, which operation cannot be effected without displacing the stop.
It is an object of the present invention to eliminate the above mentioned disadvantages of the known waxing device and in particular to provide a device, which:
a) ensures constant waxing of the yarn, in particular independently of the weight of the wax body and of the friction of the wax body on the guide pin, b) during the spinning start-up process on an open-end spinning unit does not disturb the operators in any manner, c) permits quick change-over from waxed yarns to nonwaxed yarns, without any dismantling of parts, particularly also without dismantling the wax body itself, and d) permits simple, economically feasible and reliable design.
According to the invention there is provided an open end spinning machine comprising a winding device arranged to wind a yarn on a bobbin package, a traversing device operable to cause yarn being supplied to the package to cover a traversing triangle and a device for waxing the yarn, wherein the said waxing device comprises a substantially cylindrical wax body which is axially movable and also rotatable on a guide pin, the pin having an axis which when in a working position, is substantially at right angles with respect to a plane containing the traversing triangle of the yarn, a stop determining the axial position of the wax body on the pin during operation, and means for guiding the yarn in its travel to the package in a path in which it is enclosed between an end face of the wax body and the stop, thereby to wax the yarn, the guide pin being pivotable about an axis which is substantially horizontal and parallel to the said plane containing the traversing triangle, from the working position to a rest position outside the plane containing the traversing triangle.
In a preferred embodiment of the invention the stop is a cover supported on the guide pin.
The invention will now be described with reference to the accompanying drawings in which:
Figure 1 is a perspective view of a waxing apparatus on an open-end spinning unit, Fig 2 schematically illustrates the waxing apparatus of Figure 1 in cross-section and Figure 3 is an enlarged cross-sectional view of another embodiment of the waxing apparatus of the invention.
Figure 1 illustrates an open-end spinning unit I in which a staple fibre sliver 2 is transformed into a yarn in known manner by attenuation and twisting, the yarn being taken off by a pair of take-off rolls 4, 5 and being wound into a cross-wound bobbin package 6 by a winding device arranged above the pair of take-off rolls.
The pair of take-off rolls includes a shaft roll 4 extending along all the spinning units of a whole side of the open-end spinning machine and a pressure roll 5 pressed against roll 4 by any suitable means (not shown).
The winding device comprises a friction drive drum 7, a bobbin support arm 8 and a traversing thread guide 9 The friction drive drum 7 extends along all spinning units of a whole side of the open-end spinning machine and is driven at constant speed by any suitable means (not shown) The bobbin support arm 8 presses the cross-wound bobbin package 6, which is illustrated in Figure 1, as a conical cross-wound bobbin package, against the friction drive drum 7.
The bobbin package 6 is therefore driven by the friction between the friction drive drum and the surface of the cross-wound bobbin package 6 In order to obtain the frictional contact, the bobbin support arm 8 is loaded by any suitable means (not shown) The traversing thread guide 9 which moves to and fro on a traversing rod 10 extends along all spinning units of a whole machine side.
In Figure 1, the outermost positions of the traversing thread guide are designated 9 and 9 ‘, the distance between the positions 9 and 9 ‘ corresponding to the winding traverse of the cross-wound bobbin package 6 The type of winding device herein described is not, of course the only suitable type of winding device within the scope of the present invention: thus for example, a winding device with a grooved drum in which the friction drive drum also effects the thread traversing motion, or a winding device with a directly driven bobbin chuck instead of a surface driven cross-wound bobbin package can be used.
In its traversing motion the yarn covers a so- called traversing triangle between the cross-wound bobbin package 6 and a fixed point which is shown in Fig I as a nip point located on the nip line k of the pair of takeoff rolls 4 and 5, but a thread guide eyelet 1,565,282 arranged above the nip line k can of course also be provided.
A compensation rail 11 deflects the yarn path within the traversing triangle This compensation rail 11 levels out the yarn path length difference in the yarn path determined by the traversing triangle For this purpose, the compensation rail 11 has an upwardly directly convex contacting surface 12 along which the yarn slides and is deflected Owing to the presence of the compensation rail 11, the yarn path length is maintained constant over the whole traversing triangle in such a manner that the yarn tension is also maintained constant during the winding process Thus, the winding tension depends only on the ratio of the delivery speed of the yarn take-off rolls 4, 5 and of the winding speed of the crosswound bobbin package 6, taking into account the yarn elongation The waxing device is arranged within the traversing triangle limited by the two extreme thread path positions 13 and 14.
An axle 15 (Figs I and 2) is rigidly supported substantially parallel to the longitudinal elements of the machine, for example, to the rolls 4 and 7, on the machine frame The axle 15 can extend over the whole length of a side of the open-end spinning machine or also only over one or a limited number of spinning units A support member 16 is pivotably supported on the axle 15 The pivoting range of the support member 16 between two end positions is limited by a pin 17 rigidly connected with the axle 15, and protruding through a suitable opening 18 in the support member 16 Thus, the pivoting angle of the support member 16 can be determined by suitably choosing the arc length of the opening 18 The axial position of the support member 16 on the axle 15 is determined by a stop ring 19 fixed on the axle 15.
On the other side of the support member 16, a pressure spring 20 is arranged on the axle 15 between the support member 16 and a ring 21 fixed to the axle 15 in such a manner that the support member 16 is pressed against the stop ring 19 by the force of the spring The support member 16 can therefore be pivoted only if its friction against the stop ring 19 is overcome This friction is sufficient to maintain any pivoting position of the support member 16 and the elements connected with it to be described later on.
The elements described here which determine the axial position, limit the pivoting range and permit pivoting of the support member 16 under the influence of a determined force only, of course can have other shapes and designs without departing from the scope of the invention.
A cylindrical guide pin 22 is rigidly supported in the support member 16 A cover 24 provided with a mounting flange 23 is arranged at the free end of the pin 22 A stop ring 26 is provided on the pin 22 The cover 24 and the stop ring 26 are fixed on the guide pin 22 by fixing screws 25 and 25 ‘ respectively.
A substantially cylindrical waxing body 27 of solid wax is arranged on the guide pin 2 ? between the cover 24 and the stop ring 26 The distance between the cover 24 and the stop ring 26 exceeds, in its axial direction the height of an unworn waxing body 27 and the diameter of the central bore of the waxing body 27 is such that the waxing body 27 is loosely slidable on the guide pin 22.
Thus, the waxing body 27 can freely rotate on the guide pin 22 as well as slide axially between the two stops formed by the cover 24 and the stop ring 26.
In the working position of the waxing apparatus, the guide pin 22 forms an acute angle P (Figure 2) with respect to a horizontal plane, its free end supporting the cover 24 being inclined downward and being arranged approximately at right angles to the traversing surface described by the traversing yarn containing the extreme thread path positions 13 and 14 (Figure 1) and which can, of course be slightly convex.
Thus, the angle p 3 also determines the position of the traversing surface in the room The angle p 3 is such that the waxing body 27 can always slide under its own weight against the cover 24 until it is worn off and is supported thereon The angle /p thus depends, among other factors, on the sliding properties of the waxing body 27 on the guide pin 22, on the weight of the waxing body in its unworn state and in its worn-off state and on the yarn tension prevailing between the pair of take-off rolls 4, 5 and the cross-wound bobbin 6 As shown in Figure 1 the traversing yarn is guided between the cover 24 and the waxing body 27 if the waxing apparatus is in its working position, care being taken that the yarn passes along the waxing body 27 and is thus waxed in an enclosed position i e is enclosed, but not pressed, between the cover 24 and the body 27 The position of the waxing body 27 in this arrangement is such, that the yarn path is slightly deflected at the waxing body 27.
This deflection is normally small and is maintained constant owing to the fixed position of the cover 24 The deflection is clearly indicated in Figure 2 In this arrangement, the waxing rate depends only on this deflection and on the yarn tension in such a manner that it remains constant independently of the weight of the waxing body Owing to the described arrangement of the waxing body 27 in the traversing zone of the yarn, the waxing body 27 is always set 1,565,282 into rotation in the same direction by the yarn itself in such a manner that uniform wear of the whole waxing body 27 along its face surface is ensured Experience has shown that this rotation of the waxing body caused by the radial movement of the yarn on the face side of the waxing body 27 (i e.
by the traversing movement of the yarn) is decisively influenced, or is made possible respectively If the yarn would not traverse on the face side of the waxing body 27, but would merely pass along a fixed path, the waxing body 27 would not be set into rotation reliably, which would require the use of external means for rotating the waxing body The embodiment of the invention described achieves uniform wear of the waxing body in a most simple manner which also beneficially influences the functional reliability of the apparatus.
As shown in Figure 2 the guide pin 22, including all the elements thereon, can be pivoted up from its working position (shown with solid lines in Figure 2) into its rest position indicated with broken lines by pivoting the support member 16 through the angle a The angle a in this arrangement is such that the idling position of the waxing apparatus is located outside the traversing surface of the yarn where the waxing apparatus no longer presents an obstacle for the excution of a spinning start-up process by the operator Furthermore, in the pivoted-up idling position of the waxing apparatus, the guide pin 22 is inclined with respect to a horizontal plane in such a manner that its free end supporting the cover 24 points upwards Thus, in this position the waxing body 27 can fall back against the stop ring 26 which creates very favourable conditions for re-threading the yarn into the waxing apparatus during the subsequent pivoting motion back to the working position, as the yarn easily can glide into the enlarged clearance prevailing between the cover 24 and the waxing body 27.
The yarn of course glides into the clearance before the guide pin 22 is tilted back completely into its working position, i.e already during the pivoting movement itself as the cover 24 intersects with the yarn path during its pivoting-back movement in a higher position, as clearly indicated in Figure 2.
Owing to the fact that during the spinning start-up process of the yarn, with which operation, for example possible yarn end breakages are mended, the waxing apparatus is located outside the yarn path and during the subsequent pivoting back of the waxing apparatus the re-threading of the yarn is effected automatically owing to the described enlargement of the clearance, Ideal conditions thus are created for the operating personnel excluding the danger of faulty manipulations and facilitating the operation.
The yarn guide plate 28 prevents the yarn from laterally escaping from the pressure roll 5 and thus from the waxing apparatus during the so-called back-feeding of the yarn into the spinning unit 1, in which operation the yarn is fed back from the crosswound bobbin package 6 for a short time for resuming the spinning process In the normal operating position of the openend spinning unit the yarn does not contact the guide plates 28, but its guiding function is limited to the short time phase of the yarn back-feeding during the re-starting process of the machine.
Figure 3 illustrates an alternative design example of the waxing apparatus of the invention As already mentioned in connection with the embodiment according to Figures 1 and 2, the good gliding properties of the waxing body on the guide pin have a decisive influence For meeting these requirements even better, the waxing body 29 shown in Figure 3 is mounted on a guide sleeve 30 The guide sleeve 30, which can have a weighting disc 31, the function of which can be to increase the weight of the waxing body, has optimum sliding properties with respect to the guide pin 32 such that the axial slideability and the rotatability of the waxing body and the sleeve are better ensured This embodiment, has the further advantage that the guide sleeve can be made from a material more wear-resistant than wax so that the danger of the central bore of the waxing body becoming non-round or eccentric is prevented.
Furthermore, the arrangement of Figure 3 makes it possible to provide the stop cover 33 (which corresponds to the cover 24 shown in Figures 1 and 2) with a snap-on device Such a snap-on device may consist, of an open spring ring 34 which is arranged in a circular groove 35 of the cover 33 and which can adapt itself to a circular recess 36 of the guide pin 32 Other known types of quick mounting devices (e g of the type making the use of the elastic deformation properties of the cover) of course also are applicable The advantage of a snap-on device for the cover is that it makes it possible to exchange the worn off waxing body and to replace it by a new one quickly and without using tools.
In Figure 3 also the possibility is shown of rotatably supporting the guide pin 32 in the support member 37, which can be effected, by two anti-friction bearings 38 39 Thus, the friction problems of the waxing body sliding on the guide pin can be controlled more reliably, at least as far as its rotational movement is concerned.
1,565,282 The advantages of a waxing device of the present invention are the following:
a) The uniformity of the yarn waxing process.
b) The unimpaired operation during the spinning start-up process.
c) The prevention of any faulty manipulation of the waxing apparatus during the spinning start-up process.
d) The possibility of deactivating the yarn waxing process without dismantling elements on individual or on all working positions of the textile machine.
e) The simplicity, the economically feasible manufacture and the reliability of the waxing apparatus.
