APPARATUS FOR MANUFACTURING YARN, METHOD

FOR MANUFACTURING YARNS AND METHOD FOR

ADJUSTING AN APPARATUS DEVICE

OF YARNS

This invention relates to an apparatus for manufacturing yarns, comprising at least two extruders with one or more spinning plates per extruder for producing filaments, the one or more spinning plates per extruder being provided for grouping the filaments produced with the aid of this extruder. multiple filament bundles, cooling means for cooling the filaments produced by the extruders, and combining means for combining multiple filament bundles to produce yarns from the assembled filament bundles.

In addition, this invention relates to a method for manufacturing yarns using such an apparatus and a method for adapting an apparatus for manufacturing yarns to an apparatus according to this invention.

Such devices are described and illustrated, for example, in DE 10 2005 35 43 A1, CN 102628199 A, US 6,406,650 B1 and EP 0 924 321 A1.

Typically, using the extruders of such a device, separate filaments are formed from a thermoplastic plastic such as polypropylene, polyester or polyamide. The thermoplastic plastic melted in the extruder is pressed through several spin plates, these spin plates being provided with several perforations for melt-spinning the filaments. For example, one or more bundles with such filaments are formed per spin plate. Several such filament bundles are put together to form a multifilament yarn which is typically wound on a bobbin after one or more further operations.

BE2016 / 5401

It is known with such devices with, for example, three extruders, to apply plastic granulate in each extruder with deviating properties such as, for example, a different color and then to bundle filament bundles from the different extruders in order to produce a yarn with three different colors (tricolor yarn ). A bicolor yarn can be produced with two different colors. In general, multi-colored yarns can be produced. It is also known with such devices to combine several filament bundles of the same color into a so-called monocolor yarn. Multicolor and monocolor yarn are typically made on various such devices. When changing colors and / or when changing between multicolor and monocolor yarns with the same device, this device typically has to be completely cleaned and process settings have to be adjusted, which entails long switching times.

To simplify switching between tricolor and monocolor yarns, US 6,406,650 B1 and EP 0 924 321 A1 proposed adding a distribution system to such a device between the extruders and the spinnerets. When the distribution system is moved, the supply of the molten plastic between the extruders and the different spinning plates is distributed differently. Switching between tricolor and monocolor yarns, however, still requires a long machine standstill, since at least the spin plates still have to be cleaned.

The object of the present invention is to simplify the switch between the production of different types of yarns, such as, for example, monocolor yarns and yarns of different colors (multicolor yarns), with the same device, so that shorter machine standstills are required with such a switch.

This object of the invention is primarily accomplished by providing a device for manufacturing yarns, comprising:

BE2016 / 5401

- at least two extruders with one or more spinning plates for producing filaments, the one or more spinning plates per extruder being provided for grouping the filaments produced by means of this extruder into several filament bundles;

- coolants for cooling the filaments produced by the extruders;

combining means for bringing together multiple filament bundles to produce yarns from the gathered filament bundles; and repositioning means provided for arrangement after the cooling means, when the flow direction of the filaments in the device is followed and which:

o a first use is provided to leave the filament bundling together unaltered by means of the combining means to produce yarns from the filament bundles thus brought together;

o and a second use is provided to rearrange the filament bundles to form otherwise joined filament bundles to produce yarns from the otherwise joined filament bundles.

With the aid of such repositioning means, different yarn bundle combinations can be made in a simple manner. The filament bundles are repositioned with the aid of these repositioning means after the extrusion and melt spinning of the filaments to alternate between the manufacture of yarns from filament bundles that are assembled in a first way on the one hand and the manufacture of yarns from filament bundles that are assembled in a second way on the other hand . As a result, when switching between the manufacture of different types of yarns, the extruders and / or the spinning plates do not always have to be cleaned, so that the switching times can be greatly reduced. Only if the characteristics of the plastic granulate of one or more of the

BE2016 / 5401 extruders may change, it may still be necessary to clean these one or more extruders and the associated spider plates.

The filament bundles are exchanged after the filaments have already been formed and cooled, so that the ema following parts of the device become little or not soiled by these filament bundles and little or no cleaning of parts of the device is required when switching between the manufacture of different types yarns. In principle, such devices can continue to operate without machine downtime when switching, with at most a few bobbins produced yarns being lost.

More specifically, a device according to the invention can comprise a guide element for guiding this filament bundle per filament bundle, the repositioning means comprising displacing means for moving these guide elements between a first position for the first use and a second position for the second use.

The known devices always comprise one or more such guide elements. Such moving means for moving such guide elements between different positions can in practice be designed in a simple and compact manner, so that a particularly simple solution to the above problem is obtained.

Even more specifically, said guide elements may form part of said combining means of an apparatus according to this invention.

In a special embodiment, the repositioning means can comprise control means for automatically controlling the displacement means. Alternatively or additionally, such displacement means can also be designed in such a way that they can be displaced purely mechanically.

BE2016 / 5401

In a simple embodiment of a device according to this invention, the guiding elements of said filament bundles of a first said extruder form first guiding elements which are mutually coupled for simultaneously displacing these first guiding elements by means of the displacing means.

Preferably, in such an embodiment, the guiding elements of said filament bundles of a second said extruder form second guiding elements, which are mutually coupled for simultaneously displacing these second guiding elements using the displacing means.

Even more preferably, in such an embodiment, the guide members of said filament bundles of a third said extruder form third guide members attached to a base body, the first guide members attached to a first coupling member arranged movably relative to the base body and wherein the second guide elements are attached to a second coupling element, which is arranged displaceably with respect to the base body, the first coupling element being arranged displaceably with respect to the second coupling element.

More specifically, the basic body of such an embodiment may be a base plate, provided with perforations, the first coupling element being a first coupling plate, on which the first guide elements are fixed by means of fastening rods, these fastening rods being arranged movably through said perforations, for displaceably arranging the first coupling plate relative to the base plate and wherein the second coupling element is a second coupling plate, which is provided with perforations and on which the second guide elements are fixed by means of fixing bars, these fixing bars of the second guide elements being movable through said perforations arranged in the base plate for displaceably disposing the second coupling plate relative to the base plate and wherein the mounting bars of the first guide elements are displaceable through said perforations in the second coupling plate are fitted in front of the

BE2016 / 5401 movable arrangement of the first coupling plate relative to the second coupling plate.

Alternatively or additionally, the displacement means of a device according to this invention can be provided for individually displacing each guide element.

In a specific embodiment of a device according to this invention, the combining means may be provided for bringing together multiple filament bundles with filaments of different extruders, and the repositioning means in the second use may be provided for rearranging the filament bundles into differently brought together multi-filament bundle filament bundles. the same extruder.

In an alternatively specific embodiment, the combining means may be provided for bringing together multiple filament bundles with filaments from the same extruder, and the repositioners in the second use may be provided for rearranging the filament bundles into differently brought together filament bundles with filaments of different extruders.

Preferably, a device according to this invention also comprises detection means for detecting from which bundled filament bundles a yarn produced with this device is made.

The repositioning means of a device according to this invention may be provided in at least one additional use to rearrange the filament bundles so that still differently brought together filament bundles are formed to produce yarns from the still differently brought together filament bundles.

For example, it is easy to switch between the production of yarns from filament bundles brought together by means of the combining means, from filament bundles otherwise brought together in a second use and from an additional

BE2016 / 5401 uses differently bundled filament bundles, which further increases the flexibility of such an arrangement.

In addition, the object of this invention is also achieved by providing a method for manufacturing yarns, comprising producing filaments using at least two extruders with one or more spinning plates per extruder, one or more spinning plates per extruder grouping the filaments produced with the aid of this extruder into several filament bundles, cooling the filaments in the filament bundles and assembling several filament bundles after the filaments have been cooled to produce yarns from the assembled filament bundles, this method after cooling reposition the filaments comprising of the filament bundles to form otherwise joined filament bundles to produce yarns from these otherwise brought together filament bundles.

In a simple method according to the present invention, wherein said device comprises at least one guiding roller with guiding ribs, which define guiding grooves for guiding several filament bundles at a distance from each other in these guiding grooves, the filament bundles can be moved from guiding groove to reposition the filament bundles.

The filament bundles can be moved manually from the guide groove or can be moved mechanically or automatically.

In a preferred method of this invention, the yarns are produced using an apparatus of the invention described above.

The present invention will now be explained in more detail with reference to the following detailed description of a preferred embodiment of an apparatus for manufacturing yarns according to this invention. The purpose of this description is only to provide illustrative examples and to indicate further advantages and details of the invention, and thus cannot be construed as limiting the scope of the invention or the patent rights claimed in the claims.

In this detailed description reference is made by reference numerals to the accompanying drawings, in which Figure 1 shows a perspective view of part of a yarn manufacturing apparatus of this invention at guide elements in their first position;

figure 2 shows the part of the device of figure 1 in perspective at the position of the guide elements which are in their second position;

figure 3 shows the guiding elements and displacing means of the device of figure 1 in top view with the guiding elements in their first position;

figure 4 shows the guiding elements and displacing means of the device of figure 1 in top view with the guiding elements in their second position;

Fig. 5 schematically shows a device for manufacturing yarns according to the present invention.

The yarn manufacturing apparatus (19) shown in Figures 1 to 4 comprises three extruders (20) not shown, with three spinner plates (21) not shown (21) per extruder (20) for producing three times three filament bundles (1, 2, 3). Figure 5 schematically shows a device (19) for producing yarns according to this invention, with different extruders (20) with multiple spinning plates (21) per extruder (20) for producing multiple filament bundles (1,2,3) .

BE2016 / 5401

The first filament bundles (1) shown in Figures 1 to 4 were produced with the first extruder (20) and the associated spin plates (21).

The second filament bundles (2) shown are produced with the second extruder (20) and the associated spinnerets (21).

The third filament bundles (3) shown are produced with the third extruder (20) and the associated spinnerets (21).

For example, each of the extruders (20) can be filled with granules of a different color, so that these filament bundles (1, 2, 3) each comprise filaments of a respective color.

After producing the filament bundles (1, 2, 3) these are, as can be seen schematically in figure 5, dried in a drying shaft (22), after which they are passed through the drop shaft (23) to the unit shown in figures 1 to 4 (25) are guided with guide elements (4, 5, 6), and combined with further combination means to form a multifilament yarn. This multifilament yarn is then fed with the aid of guide means (24) to one or more further treatment elements, such as, for example, a texturizing channel (26), a cooling drum (27), heated stretch rolls (28) and pre-mixing (29) to finally be rolled up on bobbins. in a wrapping unit (30). Such a device (19) typically also comprises one or more reversing rollers (24) and / or guide rollers (24) and / or guide bars (16) for guiding the filament bundles (1, 2, 3) or the multifilament yarn in between.

Just before the guide elements (4, 5, 6) shown in Figures 1 to 4, oil is sprayed onto the formed filaments in the illustrated device (19). At the height of the guide elements (4, 5, 6), air is blown onto the filaments to distribute this oil and the remaining oil is collected in the collection trough (17).

The guide elements (4, 5, 6) shown comprise first guide elements (4) for guiding the first filament bundles (1), second guide elements (5)

BE2016 / 5401 for guiding the second filament bundles (2) and third guiding elements (6) for guiding the third filament bundles (3).

The second guide elements (5) are attached to a second coupling plate (10) at an intermediate distance using mounting bars (13). The mounting bars (13) are herein arranged through said perforations in the base plate (11), so that the second guide elements (5) extend on the same side of the base plate (11) as the third guide elements (6) and so that the second coupling plate (10 ) extends on the other side of this base plate (11). The mounting rods (13) are provided with a guiding displacement in these perforations, so that the coupling plate (10) and thus also the second guiding elements (5) are movable between a first position, as shown in figures 1 and 3, and a second position, such as shown in figures 2 and 4. Several perforations are made in the coupling plate (10).

The first guide elements (4) are attached to a first coupling plate (9) at an intermediate distance using mounting bars (12).
