Shustleff ABSTRACT: A multiunit spinning and spooling assembly for producing and collecting a large number of continuous monofilament or multifilament synthetic thermoplastic threads in which a drawoff godet is arranged vertically below each spinning unit with its axis of rotation parallel to the frontside of the supporting frame and/or parallel to the planar bundle of threads being drawn from the spinning unit and in which all deflection godets and spooling bobbins associated with each spinning unit have their axes of rotation parallel to each other and perpendicular to the axis of the drawoff godet. The spooling bobbins may be rotated by frictional drive rollers, and each of the resulting winding or spooling devices are advantageously arranged such that either the bobbin or the drive roller is mounted with reference to a fixed rotating axis or at the end of a swinging arm having a fixed axis, these fixed axes of the winding devices being arranged in substantially vertical alinement below the drawoff godet.

For the production of continuous synthetic thermoplastic threads according to the melt spinning process, a molten thermoplastic polymer material is supplied over a suitable conduit and through dosing apparatus to individual spinning nozzles. The polymer melt is pressed or extruded through the bores or fine openings of the spinning nozzles and formed into monofilament or multifilament threads. The threads while still in a molten or semiplastic state fall into a vertical shaft, are blown with air for the purpose of cooling and solidifying the filaments and are drawn off at high speed at the lower end of the spinning shaft and would onto bobbins or take-up spools. For this high speed winding, it is generally necessary to use several godets running at approximately the same circumferential speed, the threads looping or being guided around each godet. These godets conduct the individual threads at a constant speed to each of several bobbins or winding devices. At this point, the threads are collected in a known manner on bobbins or cops in the form of spool wound bodies.

in Pat. No. 10,134 of the Eastern Zone Office for Invention and Patent Matters (East Germany), a spinning and spooling machine is disclosed in which the freshly spun threads are first of all conducted successively over moistening or lubricating preparation rollers whose horizontal axes of rotation are mounted perpendicular to the longitudinal frame of the machine. From the preparation rollers the threads are guided over two or more deflection rollers. The threads are then conducted, successively or adjacently and singly or in pairs, through grooved drums mounted parallel to the longitudinal frame of the machine. From this point, the threads are wound individually on bobbins carried axially parallel to the grooved drums, these bobbins being arranged singly or in pairs. This particular construction requires a large amount of space, and the spacing or the intervals between two adjacent spinning nozzles must be very great.

German Gebrauchsmuster No. 1,955,042 describes a spinning assembly with winding apparatus in which a thread family first passes over two preparation rollers and then runs over two godets. ln this case, the second godet is arranged in front of the preparation rollers in such a way that these initial rollers are poorly accessible and the application or laying of the thread is severely impeded. A great disadvantage of this apparatus also arises from the fact that the axes of the second godet and the winding device associated therewith are perpendicular to a one another. For this reason, the thread family must be twisted through an angle of 90 between the second godet and the winding device, i.e. in the zone in which the running thread is guided by a traverse device during the wind ing process. Because of this twist, the threads on the second godet can climb over one another with the accompanying danger of entanglements and considerable fluctuations in thread tension. Moreovenall of the bobbins have nonequilateral traverse triangles, so that an uneven winding density is built up over the length of each individual bobbin or wound cop.

German Gebrauchmuster No. 1,728,362 discloses a spinning and winding machine whose preparation rollers, drawoff and deflection godets as well as the winding bobbins all lie axially parallel to one another. With this device, however, only one or at the most two threads can be produced and wound.

It is an object of the present invention to provide a multiunit spinning and spooling assembly which is capable of producing, treating and individually winding a plurality of threads while avoiding the drawbacks or disadvantages of apparatus previously used for this purpose. Another object of the invention is to provide a spinning and spooling assembly which will occupy a relatively small amount of floor space with easy access to the operating elements of the apparatus. Yet another object of the invention is to provide a multiunit spinning and spooling assembly which is capable of handling a large number of threads from each spinning noule in a relatively small space, while maintaining the quality and uniformity of the threads and their would packages in the form of cops or bobbins. These and other objects and advantages of the invention will become more apparent upon consideration of the following detailed specification.

in accordance with the present invention, there is provided an improvement in a multiunit spinning and spooling assembly for producing and collecting a plurality of synthetic thermoplastic threads which are melt-spun simultaneously from a spinning head to emerge from a spinning shaft and which are then conducted over preparation rollers in a planar bundle to pass around a drawoff godet and are then directed individually to a plurality of spooling bobbins. This improvement essentially includes a drawoff godet having a horizontal axis of rotation arranged parallel to a substantially vertically positioned supporting frame, one or more deflection godets positioned above the drawoff godet with means to direct a family of individual threads from the drawofi godet at spaced parallel intervals over the circumferential surface of each deflection godet, and a plurality of spooling bobbins arranged on the supporting frame below said drawoff godet for winding individual threads from a deflection godet, each of the deflection godets and the spooling bobbins having a horizontal axis of rotation parallel to one another and perpendicular to the axis of the drawoffgodet.

In a particularly advantageous embodiment of the invention, each of the spooling bobbins is rotated by a separate drive roller in frictional contact with the periphery of the bobbin being wound, with each of the drive rollers having an axis of rotation maintained parallel to the axis of its bobbin while one axis is fixed and the other axis is movable in response to the increasing diameter of the bobbin being wound, and with the bobbins or else the drive rollers with reference to their fixed axis or of rotation or with reference to the fixed turning axis of a swinging arm attached thereto are arranged in approximately vertical alinement one over the other directly beneath the drawoff godet. By arranging deflection godets above and on both sides of the drawoff godet, it is possible to achieve a very substantial saving in space in the longitudinal direction of the entire spinning and spooling machine, i.e. by occupying a greater vertical space in order to conserve horizontal space.

The apparatus of the invention is disclosed in greater detail with reference to the several embodiments illustrated in the accompanying drawing wherein:

FIG. 1 is a front elevational view of a single spinning and spooling unit as arranged on a substantially vertical supporting frame, certain conventional elements of the apparatus being omitted;

FIG. 2 is a partial sectional view taken on line 11-11 of FIG. 1 in order to more clearly show the position of individual elements mounted on the vertical supporting frame;

FIG. 3 is a front elevational view similar to FIG. 1 disclosing another arrangement for adding additional spooling or winding devices for the family of threads from an individual spinning unit;

FIG. 4 is a front elevational view similar to FIG. 1 illustrating a preferred arrangement of the spooling bobbins in substantially vertical alinement beneath the drawoff godet;

FIG, 5 is also a front elevational view similar to FIG. 1 representing another preferred embodiment in which the drive rollers of the spooling or winding devices are arrange vertically beneath the drawoff godet;

F IG. 6 is a top plan view taken on a cross section of the vertical supporting framework of the apparatus to illustrate an alternative embodiment of a suitable winding or spooling device;

FIG. 7 is a cross-sectional view taken on line VII-VII of FIG. 6 with some elements omitted; and

FIG. 8 is a front elevational view of an entire spinning and spooling assembly with intermediate portions cut away in order to illustrate the sequential arrangement of a plurality of individual spinning and spooling units having an especially preferred vertical arrangement of he the spooling bobbins beneath the drawoff godet and having deflection godets above and on either side of the drawoff godet.

In each of the FIGS. of the drawings, similar elements are identified by thesame reference numeral, and it will be understood that the invention employs conventional spinning nozzles, rollers, godets and winding devices since the invention is directed to the placement or arrangement of the individual elements of the apparatus rather than in the precise construction of the enumerated elements.

Referring first to FIGS. 1 and 2 of the drawing, a family of threads 1 emerges from the spinning shaft 2 after a molten thermoplastic polymer, e.g. nylon or polyethylene terephthalate, has been melt-spun from a suitable spinning nozzle (not shown) which is positioned above the vertical supporting frame 13 so that the extruded filaments or threads are drawn vertically downwardly through the shaft 2. The filaments or threads are cooled and solidified by flowing air through the vertical shaft or tube 2. The family of threads 1 is first pressed lightly by the thread guide pin 3 against the preparation rollers 4 and 5 so that the individual filaments or threads are a spread out into a planar bundle in which the individual threads run essentially parallel to each other. The preparation rollers run through or dip into the shallow vessels 4a and 5a, respectively, in order to pick up a liquid lubricating or moistening agent which is then applied onto the surface of the individual threads.

A drawoff godet 6 is positioned below the preparation rollers 4 and 5 such that the axes of each of the preparation rollers and the drawoff godet are parallel to each other. The drawoff godet 6 is also positioned forwardly of the face plate of the vertical supporting frame 13 so that its axis of rotation is substantially parallel to the plane formed by the family of threads being drawn from the spinning shafi 2, the outer rotating circumferential surface of the godet 6 thus being adapted to tangentially receive the vertically traveling planar bundle of threads. This drawoff godet is preferably positively driven by a motor equipped with an external rotor as partially shown in FIG. 1. Such motors are relatively small in size and can be readily mounted on the vertical supporting frame 13 without interfering with the normal operation of the spinning and spooling device.

From the drawoff godet 6, at least a portion of the family of threads is directed upwardly and laterally outwardly while passing through a thread guide bar 7 to pass around a deflection godet 8 and then pass downwardly to be collected by a winding device including the spooling bobbin 9 and drive roller 10. Since the axis of rotation of the deflection godet 8 is perpendicular to the axis of rotation of the drawofi godet 6 the family of threads is twisted by an angle of 90 as it is drawn up over the deflection godet. The thread guide bar 7 is positioned directly before the deflection godet 8 and contains a series of spaced thread guide elements 7a so that individual threads are conducted with uniform spacing and in substantially parallel alinement onto the circumferential surface of the deflection godet.

Each of the spooling bobbins 9 can actually consist of one or more individual bobbins, each of which receives an individual thread selected from the family of threads passing over the deflection godet 8. A conventional traversing device 11 having reciprocating thread guide elements 11a is positioned adjacent the bobbin 9 for proper application of the thread to its individual bobbin as it is being wound thereon.

The initially spun thread family 1 can be conducted around the drawoff roller or godet 6 and conducted only toward one side to the godet 8 in order to be split into individual threads or groups of threads for collection and winding on the bobbin assembly 9. On the other hand, as indicated by the structure in dotted lines, the initially spun and solidified threads can be split into two groups or families as they pass around the drawoff godet 6 so as to be directed upwardly and to both sides of the vertical position occupied by the drawoff godet in combination with its spinning shaft and preparation rollers. This partially split family of threads can be again separated as it passes over the first deflection godet so that one group of threads passes downwardly to the winding device while another group or set of threads is conducted laterally outwardly to another deflection godet and then downwardly into a second winding device. The apparatus is this readily adapted to handle a large number of threads or filaments which can then be wound individually or in very small groups of threads onto a large number of winding or spooling bobbins. In each case, the initial thread family 1 travels in a planar bundle which remains in a single plane, i.e. without twisting, as it passes from the spinning shaft 2 to the drawoff godet 6. Furthermore, there is no twisting or distortion of the smaller families or groups of threads as theyare drawn from the deflection godet 8 through the traversing mechanism 11 onto the spooling bobbin 9, so that each individual thread or filament can be produced and wound in a highly uniform manner and under substantially equal tension.

FIG. 3 illustrates another arrangement of winding devices staggered into two rows with two spooling bobbins 9 being associated with each deflection godet 8. It will thus be apparent that each spinning unit along an entire spinning and spooling frame can easily handle a large number of individual spinning filaments or threads as initially produced by a single meltspinning nozzle. At the same time, the entire device requires only a minimum number of operating elements, all of which are readily accessible for the initial threading or starting of the entire unit.

An especially desirable arrangement of the deflection godets and winding devices in combination with the multiunit spinning assembly of the invention is shown in detail in FIGS. 48. Although specific embodiments of the winding or spooling devices are set forth in each of these FIGS. the overall arrangement of the spinning and spooling machine can be observed in FIG. 8. Thus, each spinning unit in the assembly is arranged vertically above a supporting frame 13 and includes the individual spinning nozzles spaced horizontally above the assembly as indicated. Each spinning nozzle extrudes a large number of filaments or threads 1 which are drawn downwardly through the spinning shaft 2 and are spread out into a planar shape to pass around the drawoff godet, preferably after passing over the usual preparation rollers. The apparatus extending from the spinning nozzle to the drawoff godet can be identified as a single spinning unit in the overall assembly, and it is essential that these elements be arranged in a substantially vertical position, i.e. such that the freshly spun threads travel vertically downwardly in a planar nontwisted path during the spinning operation. Each spinning unit is identical in all of the embodiments of the invention, including those disclosed in FIGS. 1-3.

The winding devices in each of the spooling assemblies associated with each spinning unit have the same construction although the particular type of winding device employed in a single multiunit machine can be varied as desired to include different known spooling mechanisms or improved modifications thereof. On the other hand, all of these winding devices have one feature in common in that at least one member or element of the winding device has a fixed axis about which another element rotates or pivots. For purposes of the present invention, the fixed axes of all of the winding devices for a single spinning unit are arranged substantially vertically beneath the drawoff godet. In other words, either the spooling bobbins or their drive rollers are generally placed in approximately vertical alinement directly below the vertically positioned spinning unit.

In FIGS. 4, 5 and 8, the threads 1 emerge from spinning shaft 2 downwardly over the preparation rollers 4 and 5 as in FIGS. 1-3 for the initial process of spinning and application of a preparation fluid as carried out in a conventional manner. The drawofi godet 6 is arranged underneath the preparation rollers 4 and 5 so as to be axially parallel thereto at a short distance in front of the face plate of the machine. Thread guide bars 7 are mounted on this face plate on either side of the vertical spinning unit and directlybefore two godets 8 so that the first subfamily of threads from the drawoffgodet 6 is divided into individual threads running with uniform spacing over the godet 8. Thus, while the initial family of the threads 1 runs in a flat or even plane in the path from the shaft 2 to the runoff godet 6, the first subfamily split off on wi either side of godet 6 is twisted by 90 as it travels upwardly past the thread guide bar 7 and over the deflection godet 8.

The deflection godets 8 essentially serve as a stable guide member and means for conducting the individual threads in each family downwardly to the winding devices arranged vertically one over the other below the drawoff godet 6. the deflection godets 8 andv the thread guide bars 7, if necessary, can be placed outwardly from the face plate of the machine or supporting frame 13 at a distance sufficient to permit the threads delivered by the deflection godets to the winding devices to run in front of the drawoff godet6. These and other minor modifications of the apparatus will be apparent without a detailed explanation.

' Below the deflection .godets 8 and at positions beginning below the drawoff godet 6, there are situated the individual winding or spooling bobbins 9 which in each case are driven by the frictional contact of the drive rollers 10. The bobbins 9 in each winding assembly can consist of several individual bobbins corresponding to the number of individual threads being delivered by a single spinning unit, but are preferably several in number grouped on a common shaft as indicated in FIG. 2. his also possible, however, for several threads to be received together and wound on a single bobbin or spool, i.e. to produce a multithread bobbin or cop. The vertical alinement of either the bobbins 9 or their drive rollers 10 serves to keep each winding assembly in a relatively narrow vertical space, using as many bobbins as may be needed without substantially increasing horizontal space requirements.

According to FIGS. 4 and 5 of the drawings, the axes of rotation 10a of the drive rollers 10 are in a fixed or stationary position while the winding axes of the bobbins 9 are carried at the end of individual swinging arms 12 pivotedon a fixed shaft or axis 120. Of course, this arrangement can also be reversed so that the winding axes of the bobbins are in a fixed position while the drive rollers are carried turnably on a swinging arm pivoted on a fixed axis (see FIG. 8).

In FIG. 4, the fixed pivots 12a of the swinging arms 12 are in vertical alinement beneath the spinning unit, i.e. directly below the drawoff godet as viewed from the front of the machine, so that the spooling bobbins 9 remain in substantially vertical alinement throughout the windingpro'cess.

in FIG. 5, the drive rollers 10 rotate on thefixed axes 10a which are arranged in vertical alinement below the drawoff godet 6.

In FIG. 8, the winding bobbins 9 rotate on fixed axes 9a which are in vertical alinement below the drawoff godet 6. in this case, each drive roller 10 is carried at the end of a swinging arm in the same manner as accomplished with reference to the bobbin swinging arms in FIGS. 4 and 5.

Where either the spooling bobbins or their drive rollers are carried on a swinging arm, it is a conventional practice to provide a so-called force accumulator (not shown) in the form of a weight or spring which will vary the force of frictional contact of the drive roller against the outer circumferential surface of bobbin or cop being wound as the diameter of the winding increases. Furthermore, such weighted or springurged swinging arms ensure a positive contact pressure of the drive roller against the spooling bobbin throughout the entire winding operation. Thus, in F168. 4, 5 and 8, the contact pressure between each bobbin and its drive roller is at least equal to the weight component of the wound bobbin or of the drive roller, i.e. the component of the weight of the individual element taken on a line which is perpendicular to the line of contact or common tangent line of the bobbin and drive roller.

This minimum contact pressure is preferably increased by' a" conventional force accumulator, e.g. a weight or springloaded means connected to the swinging arm.

The winding device shown in FIGS. 6 and 7 represents an alternative construction without a swinging arm. in this instance, the face plate 13 of the vertical supporting frame has a slot or opening 14 through which the lug or base member 15 protrudes outwardly from the frame. In this lug 15, there is rotatably mounted two or more bobbins 16 which are driven by the drive roller 18 mounted on drive shaft 17 held in a fixed rotatable position on the frame. By means of a suitable force accumulator, i.e. a weight or spring (not shown), the bobbins 16 can be maintained with the desired contact pressure against the drive roller. As the diameter of the windings 16 increases, the bobbin lug 15 moves away from the drive roller, this result being achieved by connecting the lug 15 to any suitable means capable of providing a lateral sliding move ment of the entire winding unit, i.e. the bobbins 16 together with the supporting lug 15.

For example, a special sliding arrangement for the lug 15 includes a guide rod or shaft 19 mounted on brackets 20 and 21 which in turn are attached to the vertical frame 13. The lug 15 is enlarged to provide a bearing housing 22 in the form of a bearing eye into which there fits a guide sleeve or bud bushing 23 surrounding a ball bearing member 24 which permits the housing 22 with lug 15 to slide longitudinally or axially along the rod- 19. The weight of the bobbins 16 is absorbed over the guide arm 25 extending at a horizontal right angle to the lug l5 from'the housing 22 by means of small rollers 26 which are carried or supported on one shank of theguide rail 27. This guide rail is also attached firmly to the frame 13, e.g. by brackets 21 and 22, so that the small rollers 26 engage the guide rail and are restrained from movement other than travelling along the guide rail 27 on its inner shank surface.

When using the winding device shown in F 16$. 6 and 7, the fixed or stationary rotatable drive shafts 17 of the drive rollers 18 are arranged in vertical alinement below the vertical spinning unit as generally shown in FIG. 8.

in all of the embodiments ofthe invention, the drive rollers can be positively driven by any suitable motor or groups or motors, preferably at the same speed so that all of the winding devices are synchronized with each other. Such conventional motors are easily mounted on the supporting frame 13 without interfering with the thread producing and winding operations. On the other hand, it is especially advantageous to employ motors of the external rotor type or so-called shell motors for the operation of the drawoff godet 6.

So as to achieve a maximum amount of spinning and winding equipment in the smallest area of floor space, it is particu larly desirable to arrange the deflection godets so that at least one is on either side of the vertically positioned spinning unit while also arranging the associated winding devices in substantially vertical alinement below ad and preferably slightly forward of the spinning unit. In this manner, a large number of winding units or individual spooling bobbins combined with a. single spinning unit can be placed in a narrow vertical space, and the number of spinning units and the longitudinal direction of an'entire spinning winding assembly can be markedly increased. This in turn permits the production and winding of a larger number of filaments or threads in a relatively small space.

The apparatus of the invention also has the advantage that the generated surface or path of the family of threads in the spinning unit, i.e. from the spinning shaft to the drawoffgodet, runs in a level or even plane and is not twisted so that the individual filaments or threads are equally stressed or tensioned at a time when, as experience has shown, they are not yet fully solidified in the spinning shaft or even as then they emerge therefrom. Also, the planar surface spanned by each thread family or one of the subfamilies between each deflection godet and its subsequent winding devices remains in a single plane without twisting. This arrangement completely avoids the tendency of individual threads to climb over one another or to become entangled in one another as will otherwise occur during the traversing movement of the threads in this section of the winding operation.

Moreover, the thread guide bars or similar spreader means positioned directly before the first deflection godet and preferably before each deflection godet has the'advantage of accurately spacing the individual threads and leading these individual threads over the deflection godet in such a manner that each thread lies precisely over the middle of its spooling bobbin on which it is being wound. Thereby, one can achieve equilateral traversing triangles at each winding position, i.e. the sides of the triangle formed by the path generated by the thread as it runs from the deflection godet as the apex to the width of the bobbin as a base are equal to each other. Such equilateral traversing triangles are known to be highly beneficial in obtaining properly wound bobbins or cops.

The apparatus of the invention thus not only permits a more efficient use of available space with a high output of melt-spun continuous thermoplastic threads but also provides a substantial improvement in the quality and uniformity of the finished threads since the tension and traversing movements of the threads can be maintained under ideal conditions. In achieving these results, substantial modifications can be made in specific elements of the spinning and winding assembly and minor modifications can be made in the particular position or arrangement of these elements without departing from the spirit or scope of the invention as set forth in the appended claims.
