Description

The invention relates to a spinning device for producing a plurality of threads according to the preamble of claim 1.

A distinction is made in the production of threads by melt spinning between undyed, monochrome and multicolor threads that are different Require spinning devices. Especially in the manufacture of multi-colored Carpet yarns are used devices that have several in one spinning station Extrude different color filament bundles and then extrude them Combine the filament bundle into a thread. Such a device is described for example in EP 0 485 871. In the known device there is a corresponding melt flow for each color by means of an extruder generated. A filament bundle is created in the spinning station for each color, whereby all filament bundles of the spinning station are combined to form the multicolored thread become. Several extruders are thus assigned to the spinning station. In practice it is a large number of spinning stations arranged side by side. The Melt flows of the extruders through several distributor pumps to the individual ones Split spinning stations. Depending on the design of the distributor pump several spinnerets are supplied simultaneously by a distributor pump, the spinnerets are each assigned to a spinning station. such Spinning devices are therefore available according to the number of colors Production of a multi-colored thread designed per spinning station.

In practice, however, there is a desire to use such a spinning device also produce single-colored threads. However, it is known that single color threads have a smaller thread titer than multi-colored threads. So is one Production of single-colored or undyed threads with the known device only with significantly lower production output or with thread titer that is too small no longer possible.

Furthermore, it is necessary that all linked via the melt guide Make spinning positions of the same color and of the same thread. This results in high color changes in particular Production losses until all spinning positions associated with the melt guide are changed to the new color.

Accordingly, it is an object of the invention to provide a spinning device mentioned type in such a way that multicolored, monochrome or uncolored Threads can be produced with essentially unchanged production output. Another object of the invention is to provide a device with flexible, on the adapted thread guide and thread guide for each thread produced create.

This object is achieved by a spinning device with the Features of claim 1 solved.

Further advantageous developments of the invention are in the subclaims Are defined.

A first solution to the problem is given by the fact that the spinnerets of the neighboring spinning positions are arranged side by side in such a way that at least a filament bundle of the one spinning station with at least one filament bundle the other spinning station can be combined into a thread. The special one The advantage of this invention is that the number of filament bundles increases a thread can be summarized, can be varied. So there is Possibility of a larger number when producing a multicolored thread bundle of filaments into a thread and during production a single color or an uncolored thread a smaller number of Bundle of filaments or just a bundle of filaments. So that can with the same production output, both a multicolored thread with a large Thread titer as well as a single-colored thread with a small thread titer become. As an example, for a spinning device with two spinning positions, which each have three spinnerets, optionally three threads through each Combining two filament bundles or two threads by combining of three filament bundles. However, it is also possible that Spinning filament bundles without threading them into a thread.

The development of the invention according to claim 2 is particularly advantageous to to produce several threads in parallel side by side at the same time.

To make at least one thread by combining two Further training is filament bundles of neighboring spinning positions the invention according to claim 3 particularly advantageous. Here is the distance between a spinneret arranged at the edge of the spinning station to form a neighboring spinneret of the other spinning station is the same or slightly larger than the distance between two adjacent spinnerets of one of the spinning positions. This ensures that the distance between the spinnerets and the The points of convergence of the threads are the same for each thread. So that can Thread guiding devices of the spinning device both during manufacture of multi-colored threads as well as in the production of single-colored threads be used equally.

In the event that several filament bundles of adjacent spinning positions to one Thread are summarized, it is advantageous if the distance between two spinnerets of adjacent spinning positions is made smaller than the distance the spinnerets one of the spinning positions. Such training the Spinning device also enables the filament bundles to be combined multiple levels.

A particularly preferred development of the invention is defined in claim 5 given. Each of the spinning positions has three in a row Spinnerets on. In the production of multicolored threads in everyone A spinning nozzle extrudes a filament bundle of a certain color, see above that a three-colored thread can be produced. When producing plain or undyed threads are in each of the three spinnerets of a spinning station filament bundles of the same color are produced. In this case, per pair of spinning stations produced three threads simultaneously. This further training is particularly advantageous to produce BCF yarns with appropriate further treatment of the threads.

The particularly preferred development of the invention according to claim 6 shows the particular advantage that in a spinning station in the manufacture of a solid or uncolored thread is the melt of an extruder is processed. This allows threads with high uniformity in their Make composition. The extruders and the distribution pumps are included connected to each other by a valve unit, the multiple switching positions having. Each spinning position is in one of the switch positions of the valve unit Assigned extruder. So there is a possibility that the spinning stations in the Spinning device with differently colored filament bundles for production colored threads can be operated. A particular advantage of the invention is that color changes in the spinning station quickly and without great Production losses are feasible.

In the second switching position of the valve unit, each of the distributor pumps is one Spinning station assigned to one of the extruders, so that the spinnerets of the spinning station extrude the polymer melts of several extruders. In this setting multicolored threads are advantageously produced.

Of course, the valve unit could be a known stationary one Distribution block are formed, which if necessary against a second Distribution block is replaced. It would also be possible to use the distribution block run several plates, so that only to change the melt guide one or a part of the plates is designed to be exchangeable.

The development of the spinning device according to the invention according to claim 9 significantly increases the flexibility of the device. Here is one Winding device with several winding stations for winding the threads one coil is provided, in which the number of winding positions is larger is the number of upstream spinning positions. This can be used in manufacturing Assign a winding station to multicolored threads for each spinning station. The Winding stations, which are arranged between two adjacent spinning stations, in this case remain out of service. Only when producing single-colored threads a coil is wound in each winding station.

To combine the filament bundles, a Thread treatment facility proposed the multiple treatment stations having. The number of treatment stations is greater than the number of upstream spinning positions. So that is when the manufacturing process is changed no modifications of the devices required to the appropriate number of threads. When making single-colored threads in each Treatment station treated a thread.

The treatment stations are advantageously designed as texturing nozzles, so that a crimped thread can be produced.

However, it is also possible to bring the filament bundles together by means of a Swirl nozzle inside the treatment station. to Generation of the crimp in the thread will be the filament bundle Textured enema in the swirl nozzles.

The use of the device according to the invention is particularly noteworthy by their great flexibility in the production of threads. With the Use of the device has succeeded in threading high quality threads to produce monochrome or multicolor versions.

Further advantages are based on some embodiments below Reference to the accompanying drawings described in more detail.

The extruder 1.1 is at the outlet via a melt line 2.1 a valve unit 3 connected. Extruders 1.2 and 1.3 are also each connected to the valve unit 3 via a melt line 2.2 and 2.3. The Valve unit 3 is explained in more detail elsewhere in the description. The Valve unit 3 has three melt outputs, which go through the melt lines 6.1, 6.2 and 6.3 are each connected to a distributor pump 4.1, 4.2 and 4.3. The distributor pump 4.1 is controllably driven by a drive 5.1. As well the distributor pumps 4.2 and 4.3 are driven by the drives 5.2 and 5.3 driven.

The distributor pumps 4.1, 4.2 and 4.3 are double pumps executed so that each pump has two pump outputs and the over the Melt line 6 supplied melt flow divides into two equal substreams. The distributor pump 4.1 has a pump outlet via the distributor line 7.1 connected to a first spinneret 9.1. The spinneret 9.1 is in one Spinning station 8.1 included. With the second pump output is the Distributor pump 4.1 through the distributor line 7.2 with a spinneret 9.4 connected, which is arranged in a second spinning station 8.2.

The device in FIG. 1 is exemplary with two spinning positions 8.1 and 8.2 shown. In practice, up to eight or ten spinning positions are next to each other operated simultaneously in one device.

The spinning stations 8.1 and 8.2 each have three spinnerets. The for Spinneret 9.1 adjacent spinneret 9.2 of the first spinning station 8.1 is through the Distribution line 7.3 with a pump outlet of the distribution pump 4.2 connected. The third spinneret 9.3 of the spinning station 8.1 is over the Distribution line 7.5 coupled to a pump outlet of the distribution pump 4.3.

The spinnerets 9.1, 9.2 and 9.3 of the spinning station 8.1 are in a row arranged one behind the other, each spinneret one of the distributor pumps assigned. The spinnerets 9.4, 9.5 and 9.6 of the second spinning station 8.2 are also arranged in a row, the spinning stations 8.1 and 8.2 in the same Level and are fixed at the same height in the device. The spinnerets 9.4, 9.5 and 9.6 of the spinning station 8.2 are over the separately running Distribution lines 7.2, 7.4 and 7.6 each connected to one of the pumps.

Here, the distributor pump 4.1 of the spinneret 9.4, the distributor pump 4.2 is the Spinneret 9.5 and the distributor pump 4.3 assigned to the spinneret 9.6. In every the spinnerets 9.1 to 9.6 produce a filament bundle 10.1 to 10.6. The Filament bundle consists of a variety of strand-like filaments that are made up of Die holes of the spinneret are extruded. The filament bundles 10.1 to 10.6 pass through a cooling section, so that the filaments of the filament bundle solidify. Then the individual filaments of the filament bundle 10 are over a thread guide 11 bundled. Then follows in the thread running direction Thread treatment device 12. The thread treatment device has several work stations, each of which is formed by a texturing nozzle 13. In Fig. 1, the thread treatment device 12 has a total of three Workstations. In the first work station, which through the texturing nozzle 13.1 is formed, the filament bundles 10.1 and 10.2 are introduced. Within the Texturing nozzle 13.1, filament bundles 10.1 and 10.2 become one common thread plug pent up. Then the thread plug is closed a thread 15.1 resolved. The thread 15.1 is wound up by a winding station 16 withdrawn from the stopper and in a winding station 17.1 to a coil 20.1 wound.

In the second processing station 13.2, the filament bundles 10.3 and 10.4 introduced together. The filament bundle 10.3 is in the first spinning position 8.1 generated by the spinneret 9.3. The second filament bundle 10.4 is in the second spinning station 8.2 generated in the spinning station 9.4. Both filament bundles are brought together into a thread 15.2 by the texturing nozzle 13.2. For this purpose, the spinning stations 8.1 and 8.2 are arranged in such a way that the external spinnerets 9.3 and 9.4 have a distance from each other, which in is essentially equal to the distance between the spinnerets of the Spinning station 8.1 or the spinning station 8.2 is observed. So the thread can be 15.2 by combining the neighboring filament bundles 10.3 and 10.4 two spinning positions 8.1 and 8.2 with the same thread guide as in the create neighboring workstations. The thread 15.2 is in one Winding point 17.2 of the winding station 16 is wound into a coil 20.2.

The third work station is formed by the texturing nozzle 13.3. In the Texturing nozzle 13.3, the filament bundles 10.5 and 10.6 of the spinning station 8.2 merged into a thread 15.2. Here, too Filament bundles 10.5 and 10.6 to a thread plug in the texturing nozzle upset and then dissolved to thread 15.3.

The winding station 16 has a winding station for each work station, so that a total of three winding stations 17.1, 17.2 and 17.3 are provided. To the Winding stations 17.1 to 17.3, the winding station 16 has a long cantilever Winding spindle 22 on The winding spindle 22 is supported on one side and via the drive 21 drivable. On the winding spindle 22 there is one in each winding station 17.1 to 17.3 Sleeve 19 clamped. The sleeve 19 serves to receive the coil. The thread 15 runs to the winding station 16 via a head thread guide 18. To the The thread is deposited on the bobbin by a traversing device back and forth along the coil length. On the representation of the The traversing device was dispensed with here.

In the spinning device shown in Fig. 1, the Thread treatment device 12 further devices for thread guidance, for Stretching, for thermal treatment or for vortexing downstream. For example, the filament bundles 10.1 to 10.6 are withdrawn from the spinnerets 9.1 to 9.6 by a delivery mechanism.

In Fig. 1 is the use of the device for the production of monochrome or undyed threads. The extruders 1.1, 1.2 and 1.3 produce one monochrome or an undyed polymer melt of a given polymer. Thus, each spinneret becomes the spinning station via the distributor pumps 4.1 to 4.3 8.1 and 8.2 fed the same polymer melt. Each of the spinnerets 9.1 to 9.6 thus creates a similar filament bundle. Summarizing the Filament bundles in the texturing nozzles 13.1, 13.2 and 13.3 thus lead to an in thread of the same kind.

2 shows a further exemplary embodiment of an inventive device Device shown schematically. The spinning device according to FIG. 2 only differs in the way the filament bundles are treated as well as in the summary of the filament bundles into threads. The The melt flow until the filament bundles are produced is identical to that Device from Fig. 1. In this respect, the previous one is referred to at this point Description referred.

In the spinning device shown in Fig. 2 are between the Winding station 16 and the spinning stations 8.1 and 8.2 a plurality of texturing nozzles 23 arranged side by side. For each spinneret 9.1 to 9.6 of the spinning positions 8.1 and 8.2 is a texturing nozzle 23 in the thread running plane of the one produced Filament bundles 10.1 to 10.6 arranged. Between the texturing nozzles 23 and the winding station 16 is the thread treatment device 12 for Combine the filament bundles arranged. The Thread treatment device has a total of two workstations that is each formed by a swirling nozzle 14.1, 14.2 and 14.3.

In the situation shown in Fig. 2, the device is used to a to produce multicolored thread. For this purpose, in each of the extruders 1.1, 1.2 and 1.3 produces a melt of a certain color. Via the valve unit 3 Melt flow of an extruder one of the distributor pumps 4 supplied. So can for example, the extruder 1.1 with the distributor pump 4.1, the extruder 1.2 with the distributor pump 4.2 and the extruder 1.3 with the distributor pump 4.3 be connected. Each distributor pump now has a different color Polymer melt. A distribution takes place through the distribution lines 7.1 to 7.6 of the partial melt flows such that in each spinning station 8.1 and 8.2 three different colored filament bundles are generated. The filament bundles 10.1 and 10.6 each pass through a texturing nozzle and become one Plug up and then into a crimped filament bundle dissolved. The crimped filament bundles 10.1, 10.2 and 10.3 of a spinning station 8.1 then become a thread 24.1 in the swirling nozzle 14.1 merged. The thread 24.1 is in the winding station 17.1 Winding station 16 wound up to the coil 20.1. The filament bundles 10.4, 10.5 and 10.6 of the second spinning position 8.2 are after the texturing by Swirling nozzle 14.3 brought together to form a thread 24.2. The thread 24.2 becomes the coil 20.3 in the winding station 17.3 of the winding station 16 wound. The middle work station of the thread treatment device 12 and the middle winding point 17.2 of the winding station 16 remain out of operation or are idle. When producing multicolored threads advantageously creates a thread per spinning station, so that the work station or Keep winding point between two spinning stations out of operation. However, it is also possible, thread treatment facilities and winding stations at the Production of multi-colored threads with the number of work stations and To provide winding stations that correspond to the number of spinning stations. Likewise it is possible to provide a treatment device and for each spinneret of a spinning station to provide a winding station.

In Fig. 3 is an embodiment of a melt guide in the Spinning device according to the invention shown schematically. Here was on the presentation of the merger and the further processing of the Filament bundle and the threads waived. In Fig. 3.1 the melt guide is for Production of multi-colored threads shown. 3.2 is the Melt guidance in the manufacture of single-colored or undyed threads shown. The following description applies - unless otherwise stated - for both figures.

Two extruders 1.1 and 1.2 are provided to produce the polymer melts. The extruders 1.1 and 1.2 are at the outlet via the melt lines 2.1 and 2.2 connected to a valve unit 3. The valve unit is manually adjustable and can be adjusted between two switch positions. Through the Valve unit 3, the melt lines 2.1 and 2.2 corresponding to one of the selected switching positions with the fuse lines 6.1, 6.2, 6.3 and 6.4 connected. The fusible lines 6.1 to 6.4 are each at the pump inlet a distributor pump 4 connected. So the melt line 6.1 leads to the Distribution pump 4.1, the melt line 6.2 to the distribution pump 4.3, the Melt line 6.3 to the distributor pump 4.2 and the melt line 6.4 to the distributor pump 4.4. The distributor pumps 4.1 to 4.4 are each as Double pump designed so that they have two pump outputs. The Melt flow is through the distributor pump 4 in two equal partial flows divided and via the respective pump outputs to the connected Distribution lines 7.1 to 7.8 continued. The distributor pumps 4.1 to 4.4 supply a total of four spinning stations 8.1 via the distribution lines 7.1 to 7.8 to 8.4 each with two spinnerets 9. This results in one device, the four side-by-side spinning positions 8.1 to 8.4 with the spinnerets 9.1 to 9.8. In each of the spinnerets 9.1 to 9.8 a filament bundle 10.1 to 10.8 generated. The allocation of the distributor pumps to the spinning stations provides that the distributor pumps 4.1 and 4.2 supply the spinning stations 8.1 and 8.2. Here, the spinneret 9.1 of the spinning station 8.1 and the spinneret 9.3 is the Spinning station 8.2 assigned to the distributor pump 4.1. The spinneret 9.2 the Spinning station 8.1 and 9.4 of spinning station 8.2 is assigned to the distributor pump 4.2. Accordingly, the supply of the spinning stations 8.3 and 8.4 by the Distributor pumps 4.3 and 4.4 made in the same way, so that the two Spinnerets of a spinning station are each assigned to a distributor pump.

3.1 shows the valve unit 3 with the switching position 1. Here, the Melt flow of the extruder 1.1 led to the distributor pumps 4.1 and 4.3. The melt flow of the extruder 1.2 becomes the distributor pumps 4.2 and 4.4 guided. This ensures that in each spinning station 8.1 and 8.4 Filament bundle from the melt flow of the extruder 1.1 and a Filament bundle is generated from the melt flow of the extruder 1.2. This Melt guidance is therefore particularly suitable for multi-colored threads manufacture. For example, a blue one is colored in the extruder 1.1 Melt and in the extruder 1.2 produces a yellow colored melt. In the Spinning positions 8.1 to 8.4 thus become blue and yellow respectively Filament bundles created, which brought together into a blue-yellow thread become.

In the situation shown in Fig. 3.2, the valve unit is in the Switch position II. The melt flow of the extruder is in this switch position 1.1 led to the distributor pumps 4.1 and 4.2. The melt flow of the Extruder 1.2 is routed to the distribution pumps 4.3 and 4.4. So that will achieved that in the spinning positions 8.1 and 8.2 only the melt of the extruder 1.1 is processed and in the spinning positions 8.3 and 8.4 only the melt of the Extruders 1.2. This melt guide is particularly suitable for monochrome or to produce non-dyed threads. It is possible that in the Spinning stations 8.1 and 8.2, for example, two blue threads and in the spinning stations 8.3 and 8.4 two yellow threads are generated.

The valve unit shown in Fig. 3 can be easily in a Use the spinning device according to Fig. 1 or Fig. 2. For this, the Spinning device according to Fig. 1 or Fig. 2 expanded by four spinning positions, wherein two spinning stations would be supplied by three distributor pumps. Accordingly, an extruder fuse in one of the switch positions would be the Valve unit assigned to a total of three distributor pumps. The valve unit 3 would have three connections for the extruders and nine connections for the Distributor pumps. If one now considers the device shown in FIG. 1, it would in this case the valve unit 3 is in a switch position in which the distributor pumps 4.1, 4.2 and 4.3 are simultaneously supplied by the extruder 1.1 become. The melt flows of the extruders 1.2 and 1.3 would become the led neighboring spinning stations.

In the spinning device shown in FIG. 2, the valve unit would advantageously be in a switch position in which the distributor pump 4.1 the Extruder 1.1, the distributor pump 4.2, the extruder 1.2 and the distributor pump 4.3 is assigned to the extruder 1.3.

The device according to the invention is particularly suitable for BCF yarns for example from polyester, polyamide or polypropylene.

The devices shown in Figures 1 to 3 are exemplary. The The device according to the invention can also be designed with several spinning stations be that each contain only one spinneret and from only one extruder be supplied. With such a spinning device can be per Spinning a thread from a bundle of filaments or by combining two adjacent spinning positions from two filament bundles spin a thread. This will achieve a high degree of flexibility in the manufacture of the threads.
