Description

Winding and conveying device for rayon threads o. The like. It is known in the production of artificial silk threads o. The like. In a continuous operation Winding or conveying devices consisting of two co-operating entden rod drums to be used, around which the thread is wound helically and on which the thread is subjected to the various post-treatments.

Uin achieve a compact design zii as possible, are with a known conveyor of this type .die two to separate, each other eccentric Axles rotating rod drums arranged one inside the other, in such a way that the Bars of one drum between two adjacent bars of the other drum lie. At the. Rotation of the drums experience the rods of one drum to them the other drum such an adjustment in the radial and axial direction, that the thread wound onto the common jacket of the drums in which Trommellängsa.chsen is further funded. In this known device are .die Rods of each drum are hinged at both ends to supporting disks, which revolve around different axes of rotation. Such a design is already over Basically disadvantageous because the many joints in the company are very heavily worn are subject, especially since they are used to treat the thread chemical liquids and the like are exposed, there are also from individual rod sets compound Isäfi.gtromineln known, in which the rods of one set independently during a rotary movement of the drum by means of a cam device be moved back and forth from one another in order to give your thread a conveying motion granted.

It has also already been proposed that the rods of the nested Drums to be rigidly attached to supporting disks, the latter being offset to one another Rotate arranged axes of rotation. The drum bars attached to one support disk are here in the slots of the opposite support disc of the other Adjustable drum bars. In this design, they are at an angle to each other directed axes of rotation of the two support disks in one and the same plane, cut so in one point. .

In contrast, the conveying device according to the invention differs in that the axes of rotation .der consist of rods rigidly fastened separately on rotatable support disks existing moving drums in each other arranged in parallel planes and at an angle are offset from one another; ie the diagonally also run. @ lea 13rehaehscn der Stabtroin- so do not intersect.

The device according to the invention can be used wherever it is a question of winding up threads and conveying them on. In the following, the device is described as part of a Sp: nn, mascliin.e for the production of rayon in a continuous operation. In such machines, the threads are subjected to various treatments while they are on the winding or conveying devices. The rayon threads can be produced from cellulose acetate, cellulose nitrate or viscose spinning solutions, for example.

The container i (FIG. 3) is used to hold a hardening bath 2, iri that the viscose threads are spun through a spinneret 3. The thread 4 leaves the bath and is fed through guides 5 to a drum 6 and from this to further drums 0, 6L, etc. On each of these drums the thread, as shown in FIG. 4 shows helically wound. The winding progresses in the axial direction of the drum, namely in the case of successive drums in opposite directions. The threads are continuously fed to the individual drums and at the same time completely diverted from them again. The thread is treated differently on each drum until it is wound onto the end of a Saininel device in the finished or partially finished state.

As shown in FIGS. 1, 5 and 6,]), each drum exhibits two disks c) of the IiöPfell 7, 8, which on their outer t mfang in cicr axial direction Carrying running rods 12. 14.. The rods on one disc are each rods carried between the whole of the other disk. 1) which has whole structures hence the appearance of a zvlinclrisclieli cage.

As FIG. 6 shows, the disk o. The like. 7 with a hub o is firmly seated on a 'wave io and is on her z. B. geicliert by a screw ii. the Disk carries on its circumference a number of rods 1? Which in the direction of the axis io v; rlattfen and, in the embodiment according to FIG. 6, move away from the disk 7, 9 out to both sides. extend towards. This "sale of the conveyor drum" is perfect cylindrical in shape; its axis coincides exactly with the shaft io. the outer edges of the rods 12 so lieäeil on a cylindrical surface.

The second part of the conveyor drum also consists of a disk B. 13, on the outer circumference of which bars 1.4 are provided. While the rods 12 extend fully from the disk 7, 9 in both directions, the rods 14 of the second drum part protrude from the surface of the disk body 8 in only one direction. The arrangement is such that the rods 14 each between the rods. 12 lie and all. Bars the length of the dyke. This drum part 8 is also a purely cylindrical body, d.li. the outer lines of the rods 14 also lie on a cylindrical surface. However, this cylinder is not mounted finitely on the same axis as the shaft. The disk 8 does not sit directly on the shaft io, but becomes one of a bearing head. Stä llders 15 worn. This bearing head for .den disc body 8 is now designed so that the axes of the two drum parts - and 8 do not coincide and also do not necessarily run parallel to one another. However, they are relocated to each other in such a way that the axes of the two drum parts lie in planes that maintain the same distance from each other. These. parallel planes may be horizontal planes, for example. The vertical distance between: the axes of the two drum parts 7 and 8 can therefore be assumed to be a uniform distance over the entire length of the drum. In addition, however, the axis of one drum part is also laid within its plane at an angle to the axis of the other drum part. The schematic representation according to FIG. Z shows these conditions in a greatly exaggerated state. : According to FIG. 2, the ramming part 7 may be viewed as l: anzeiltri: cli for wave io; the Trorninelteil 8 is offset with respect to the part 7 scitwä res. In addition, the drum part 8 has then experienced an angle adjustment in this special plane, which it occupies with reference to part drum part 7. For a drum with a diameter of 25 cm, the lateral full vertical distance between the two axes is, for example, approximately 3 in-in. The angular adjustment was only a few degrees and, with a roller length of 122 cri, accounts for a deviation of perhaps two millimeters: the number of rods in both drum parts is expediently chosen as large as possible. As FIG. 5 shows, the bars of one drum part always lie between the bars of the other drum part. The one drum part. for example; serves as the driving body, while the other drum part 8 is only taken along. The Trorninelteil e sits loosely rotatably on a bearing sleeve 16 in the stand 15 (Fig. 6), namely the sleeve i6 is arranged eccentrically with respect to the shaft io. In addition, the axis of the bearing sleeve is adjusted at an angle to the shaft io.

If the shaft io is driven in any way, the two troinel parts also rotate together, namely the drum part 8 is carried along with the connection of decorative rods 1a and about full (learn directly driven drum part 7). As a result of the lateral displacement of the axes of the two Troninielteile protrude to each other, the bars ia of the drum part: 7 with each rotation on a part of the Troittntltinifaiige radially over the bars 1a. of the other drum part. This can be seen, for example, from the lower part of Fig. 5. It finds Thus, to a certain extent, there is a radial displacement of one group of rods with respect to the other. As a result of this displacement of the two groups of rods relative to one another, the thread turns are lifted from one drum part and transferred to the other , i.e. 1i. a conveying movement of the thread on the drum in its axial direction brought about. Those parts of the thread turns which, for example, in FIG. 5 in the upper part on the rods 1d. of the crooked Troinniel part 8 rest, as a result of this crooked position, yen are forced to move forward in the direction of the Tronini axis.

A thread passed through one end of the drum is thus during of the winding process essentially helically wound on the drum. The individual turns thus approach each other more and more d: in the end of the drum. In this way a thread fed to the Troliiniel came on her in a large one Number of relatively closely laid turns are wound. So, ioo, zoo or more windings can be on a drum. With a diameter the drum of 25 cin can have a long thread length of for example i so wound up in will. Lets a treatment liquid flow onto the wound up rag, so the thread is concerned during a beatimniten period of treatment Solution exposed. The duration of the treatment depends of course on the speed of the run the drum and the number of turns of thread.

The slope or the distance of the individual thread vvili.dungen from each other is achieved by the mutual misalignment or @ vinlcel displacement of the axes of the two Tromntelte_le determined to each other. Depending on the angle adjustment selected, a larger or smaller slope can be caused.

From a consideration of FIG. 2 it can be seen that the thread is wound up without experiencing a longitudinal displacement as long as it is only seen in relation to the truncal part 7 which is laid horizontally to the shaft ro is located. There is a shift in the thread however, as soon as the thread hits the e-xzen trically arranged and crooked 'I.'roinrnelteil 8 explained. This is practical Misalignment and the Etzentrizit: it der two drum parts to each other very small. ln Fig. # " Is this offset for clarity shown exaggerated for half. The aforementioned skewed setting edge can be achieved in different ways. Be it for example angqno.minen that only the two the axes of the drum parts elzentriscli to- are adjusted to each other without a kelverstellung takes place, and only then a rotation about an axis takes place, which is rapid dial is directed to the wave to. Now he can Base of this axis on the shaft toi even again along the entire shaft be pushed; so he can at different n places. In FIG.

I # hurry such a drum structure can then w; ililt when it: I is about , [en thread a bit ztl `tr @ ckcn. H #. A ver rotation around an axis, @lie in the point Z ends, leads to the fact that the structure assumes a weak hedgehog shape, with a wider end or the base circle of the cone at the end opposite the point Z. This arrangement can be chosen if, as a result of the treatment on the drum, the thread tends to shrink somewhat: By the fact that the thread migrates on the drum in the direction of the smaller diameter, the risk of the thread being torn is avoided, i Otherwise it could possibly occur if the entire winding device were purely cylindrical.

Of course, depending on the choice of the point of rotation X, Y, Z or any point in between, the movement of the thread in the longitudinal direction on the drum can be determined, so that depending on this rotation in one or the other direction, the movement in the direction of: the one or the other side takes place. If one assumes, for example, in the exaggerated representation according to FIG. 2, that the drum part 8 has been set in the position shown in full lines with respect to the drum part 7, this promotes the migration of the thread from the left application end to the right . By rotating this adjustable drum part 8 in the other direction, as indicated by dashed lines, the thread will advance to the left in the longitudinal direction of the roller structure. By correctly assembling such drums, what is shown in Fig. 4 can be achieved: the thread moves to the right on the top drum, to the left on the second drum, and so on.

In the arrangement according to FIGS. I to 6, each drum is only used for Winding and unwinding of a single thread. The drumstick is just big enough to take up a certain number of turns of a thread that both stay is exposed to the treatment with a certain liquid on this drum.

However, the drum can also do so. be well trained that they are used for Can serve to accommodate a plurality of threads that are simultaneously fed to the drum. and be carried away by her. A drum designed in this way is shown in FIGS. 8 and g. On a., Such drum can then, for. B. six threads at the same time up, and, are handled.

In this embodiment, two disks or the like g ″ are provided, there is one such disk on each third of the drum structure in question. The outer ends of the arms of these disks 9ü have holes 17 (Fig. 10 and ii) to accommodate the fastening screws i8 for the ends of the rods i2a. The wave ioa, on which the disc is fixed, rotates in bearings. ig one Frame 15a. As FIG. 8 shows, the wave extends transversely through it Frame through and carries a drum on each side. On such a drum structure a large number of threads can be wound and unwound. In certain circumstances fifty or more threads can be wound on the same drum at the same time and be wound off by it. The intermediate supports 1.5 "take at the same time .the Bearings for the drum part, the bars of which lie between the bars: 12 ". These Bearings are arranged somewhat eccentrically with respect to the bearing ig for d, e shaft io. The carriers of the rods of the supplementary drum consist of discs or the like 13 " together, which are rotatably supported on the bearings 2o. Enclose these camps a cylindrical extension 21 of a plate 22 with your fixed storage rack 15 "is united. The lugs 21 are cylindrical, but they are eccentric to the bearings ig in which the shaft ioa is supported. The eccentricity of this Approaches is the same on both sides of the frame 15. The angle adjustment , the drum structure that is supported in these eccentric bearing heads, is also generated by the fact that these bearing heads have a certain inclined position take with reference to the wave ioa. Such an inclination of these approaches can be brought about without difficulty by one of the plates 22 at the ends .the drum around the shaft ioa in one direction and at the other end in the opposite direction Is rotated towards something. As a result, the bearing axis moves on one drum structure in the circumferential direction around the shaft ioa, and this angular adjustment then leads to an angle adjustment of the whole drum. In the illustrated embodiment the two plates 2z are united with the frame 1.5 "by bolts 23. These Bolts extend through circumferentially elongated slots -2.4 in the plates 22 (Fig. 12) and enter through round openings in the frames 15a, uni finally into a threaded hole in the plate 2a on the other side of the frame to enter. According to FIG. 8, a handle 25 is arranged on one of these plates. After loosening, the bolt 23 can one of the plates 22 to, to the desired angular length be rotated about their axis: this causes the inclination of the axes of the two Troinmelgebilde against each other reached.

Fig. 8 also shows. that the disc i & the skewed drum is a hub 2 <, within which, the I age 20 against the. Access to the treatment liquid opportunities and against Scliniierti, ittelccrltist overall protects lies.
