Description

  The present invention relates to a double twister spinning apparatus having the features described in the superordinate conceptual part of claim 1.

  In the spinning industry, different spinning methods are known for the production of yarn from staple fibers. These spinning methods are partly different both in terms of their production speed and their production products.

  In practice, three spinning methods are used in particular, and these spinning methods are described in detail in the patent literature for many printed materials. These three spinning methods which are advantageously used are the ring spinning method, the rotor spinning method and the pneumatic spinning method.

  In this case, high quality yarn is produced by a ring spinning method as is well known. However, the production speed in ring spinning is limited based on physical limitations that have not been overcome before. Furthermore, with this ring spinning method, only relatively small windings, so-called cups, can be produced. Since these cups have relatively little yarn material, they must then be rewound over time to form a relatively large wound body. In other words, in the working part of the winder, a large number of such cups, each produced by a ring spinning machine, must first be rewound into a suitable package type, preferably a large capacity traverse package.

  Production speeds significantly higher than in the ring spinning method can be realized by the rotor spinning method and the pneumatic spinning method. Furthermore, these spinning methods, which are significantly advantageous in terms of production speed, have the advantage that they can produce package types that can be processed directly in subsequent textile machines, for example looms, in the production process. . However, these known spinning methods have the disadvantage that a yarn quality comparable to that of yarns produced by the ring spinning method cannot be achieved.

  In the textile industry, the so-called double twister twist method is also known for the production of twisted yarns. In the twisting method, which has been known for a long time and has been described in detail in the patent literature for a large number of printed products, two yarns are twisted together by the rotation of a drivable yarn guide tube piece, whereby one twisted yarn is Arise. The formed twisted yarn is then wound up into a winding package, for example a twill package.

  Furthermore, a double twister spinning device is known from DE 10 40 950 A1. In this double twister spinning device, the feed material, preferably the sliver, drawn from the flyer bobbin by the draft device is first drawn to the thickness of the yarn and then twisted by a hollow spindle that is driven and rotated. That is, when passing through the rotating hollow spindle, the sliver is first given a first portion of the planned yarn twist. The formed yarn then advances from a subsequent yarn storage disk, which is likewise rotatably supported, through a radial opening, between the yarn guide plate of the yarn storage disk and so-called apex guides arranged at intervals. A yarn balloon is formed between them. In the apex guide, the yarn is turned and thus obtains a second part of the yarn twist.

  This yarn balloon needs to go around the entire winding device of the double twister spinning device, which leads to serious drawbacks.

  Arranging the winding device inside the yarn balloon leads, for example, to the fact that the minimum possible diameter of the yarn balloon is set by the dimensions of the winding package in combination with the winding device to which it belongs. That is, by arranging the winding device inside the yarn balloon, a relatively large yarn balloon is automatically generated, and a high tensile force load is applied to the yarn based on the centrifugal force acting on the corresponding rotating yarn, Or yarn breakage occurs.

  In order to limit the diameter of the yarn balloon and thus the load applied to the yarn to a minimum acceptable size, the winding device of this known double twister spinning device is usually compact and simple. A winding device such as that described in DE 10 40 950 does not have an edge displacement device or a ribbon winding prevention device. This leads to an unacceptable lack of quality of the package.

  Yarn turning in the apex guide region is also inconvenient. This is because such yarn turning prevents the second portion of yarn twist applied to the yarn downstream of the apex guide from sufficiently returning to the yarn balloon. Thus, the yarn has insufficient strength, especially in the areas of the relatively large yarn balloons that are strongly exposed to the risk of yarn breakage, and thus as known from DE 10 40 950 A1. Double twister spinning equipment could hardly prevent frequent yarn breakage. This known double twister spinning device could therefore not be implemented in practice.

German Patent No. 1040950

  Starting from the above-mentioned known prior art, the problem that forms the basis of the present invention is to develop a spinning device that makes it possible to spin a ring-spun yarn corresponding to the quality, and in this case, the ring spinning method In other words, it is possible to process at a production rate that is significantly higher than the production rate possible. It is desirable for the spinning device to be developed to be able to produce package types and package qualities that can be further processed in subsequent textile machines, such as looms, more directly and then without additional rewinding.

  In a preferred embodiment, the draft device has a draft device roller pair that can be driven by a separate motor, the rotational speed of each draft device roller pair being adapted to the desired draw ratio.

  In a preferred aspect, the energy and data transmission device includes a first transmission / reception device disposed outside the balloon restricting portion and a second transmission / reception device disposed inside the yarn balloon rotating during the spinning operation. Have.

  In a preferred aspect, the first transmission / reception device and the second transmission / reception device are devices that operate electromagnetically.

  In a preferred embodiment, the winding or winding device includes a device that rotates the traverse package and a yarn traverse device that traverses the yarn that rides on the traverse package.

  In a preferred embodiment, the balloon thread guide is rotatably supported in the frame.

  In a preferred embodiment, the balloon yarn guide is rotationally driven to form an additional false twist.

  In a preferred embodiment, the supply bobbin is a flyer bobbin.

  In a preferred embodiment, the spindle has a storage disk or yarn storage disk.

  In a preferred embodiment, the draft device is arranged in the storage device above the supply bobbin, and a new supply bobbin can be mounted on the storage device without problems if necessary.

  In a preferred embodiment, an opening is arranged above the drafting device, through which the roving yarn drawn from the supply bobbin and guided around the drafting device while forming a yarn balloon is supplied to the drafting device. The

  A frame is provided, the frame having a receiving device for a supply bobbin and equipped with a draft device connected to an energy and data transmission device, the frame being rotatably supported and The double twister spinning device defined by the present invention arranged on a driveable spindle has the following advantages in particular. That is, such an apparatus makes it possible to produce very high quality yarns from staple fibers in a relatively simple manner, in which case a relatively high production speed can be realized without further problems. By placing the central balloon thread guide on the opposite side of the frame from the spindle, not only is there a deliberate setting of the length of the thread balloon formed during the spinning operation, but this way A simple balloon yarn guide does not prevent the propagation of twist imparted to the yarn by the rotating spindle. That is, the double twist (twist twist) given at each rotation of the yarn balloon is immediately propagated over the entire area of the yarn balloon to the yarn outlet from the draft device. This results in a yarn that is stable and relatively insensitive to yarn breakage.

  As described in claims 2 and 3, the energy and data transmission device may have different embodiments.

  In a particularly advantageous manner, for example, the energy and data transmission device is formed as a device working wirelessly, as claimed in claim 2.

  Such a device not only works completely free of friction, but also ensures that the yarn balloon can always rotate freely during the spinning process.

  Such a free rotation of the yarn balloon during the spinning process is such that energy and data transfer is effected via a brush element as described in claim 3, which is arranged below the yarn balloon. It is also given if you are. However, such fairly inexpensive energy and data transmission devices do not work without wear. That is, such an apparatus sometimes requires maintenance work.

  According to claim 4, in a further advantageous aspect, the double twister spinning device further comprises a balloon restricting part that at least partially surrounds the frame and restricts the maximum diameter of the yarn balloon.

  With the double twister spinning device constructed in this way, it is possible to achieve production speeds that are significantly higher than production speeds possible with the ring spinning method without problems.

  According to another advantageous embodiment, the spindle can be driven by a separate motor, and an axial thread guide passage section and a radius connecting to the axial thread guide path section as defined in claim 5. Directional yarn guide passage section. Such a configuration of the spindle is simple and reliable and controlled around the axis of rotation of the spaced central balloon thread guide of the thread exiting the radial thread guide passage section. Enable rotation. That is, the thread rotates as a thread balloon about a single axis of rotation that is the same as the center axis of the spindle, where the length of the thread balloon is set by a balloon thread guide located at the center, and The diameter of the yarn balloon is set by the balloon restricting portion.

  Further, as described in claim 6, the spindle is rotatably supported in the machine base of the double twister spinning device, and the frame is positioned on the spindle via a rolling bearing.

  In this case, the frame is simultaneously prevented from rotating during the spinning operation in a force-connected manner by the rotation prevention unit. That is, on the one hand, the frame is supported on the spindle so that it can accommodate the supply bobbin and the drafting device without problems, and on the other hand the spindle can rotate the yarn at a relatively high speed during the spinning operation. Is arranged. In this case, the yarn forms a yarn balloon, and the minimum size of the yarn balloon is set by the size of the frame.

  According to claim 7 and claim 8, in an advantageous aspect, the frame rotation preventing portion is formed by a position fixing magnet (claim 7), and the first position fixing magnet is located outside the balloon restricting portion. The second position fixing magnet is attached to the frame (Claim 8).

  By using the position fixing magnet as the rotation preventing portion, the force connection type position fixing of the frame supported by itself can be easily realized. In this case, the selected arrangement of the position-fixing magnets of the anti-rotation part not only reliably prevents the frame from being accidentally rotated during the spinning operation, but such an arrangement is also possible during the spinning operation. It ensures that a free rotation of the thread surrounding the frame is always provided.

  According to claim 9, in an advantageous manner, the drafting device further comprises a plurality of drafting device roller pairs which can be driven by individual motors. The rotational speeds of these draft device roller pairs are each adapted to the desired draw ratio.

  In the draft device constructed in this way, each feed material is drawn as desired, that is to say to a predetermined yarn thickness. If desired, subsequent changes and corrections of the stretching values are possible without problems.

  In order to ensure the normal supply of energy and data to the drive part of the draft device and to the associated control and sensor device, it is particularly advantageous that the outside of the balloon restricting part as described in claim 10. An energy and data transmission device is provided having a first transmission / reception device disposed on the inside and a second transmission / reception device positioned inside a yarn balloon rotating during spinning operation.

  Such energy and data transmission devices operating wirelessly ensure that, in particular, the first and second transmitting and receiving devices are formed as electromagnetically operated devices as described in claim 11. And relatively inexpensively, energy and data can be transmitted through the rotating yarn balloon, where the difficulty in transmitting energy and data also has some adverse effect on the rotating yarn balloon. There is nothing.

  The winding device of the double twister spinning device advantageously comprises a device for rotating the traverse package and a yarn traversing device for traversing the yarn running on the traverse package during the spinning process ( Claim 12).

  Such winding or winding devices are known in various embodiments in textile machine structures and are used in large numbers.

  Such winding devices may differ significantly from one another with respect to the configuration of the yarn traversing device and with respect to the drive type of the winding package.

  The winding package may be mounted, for example, on a package drive roller and is entrained in a frictional connection by the package drive roller, i.e. rotated together. However, a driving device may be incorporated in the package frame, and the driving device rotates the winding package through the winding tube.

  As the yarn traversing device, for example, a finger yarn guide, an apron yarn guide or a yarn guide drum is known. In this case, the yarn guide drum also serves for the frictional connection of the winding package.

  Modern winding devices usually have a device that can also initiate so-called edge displacement and a device that prevents the occurrence of ribbon winding.

  In the present invention, unlike the known prior art, the winding or winding device is arranged outside the yarn balloon. Therefore, the present invention is not limited in any way with respect to the edge displacement device and the ribbon winding prevention device.

  Furthermore, as defined in claim 13, the balloon thread guide is rotatably supported on the frame and centrally with respect to the winding or winding device. This is necessary when the yarn guide opening faces in the vertical direction. If the opening faces in the horizontal direction, the thread guide may be fixedly arranged. Furthermore, as described in claim 14, the balloon yarn guide is driven to rotate, thereby providing a temporary false twist, which favorably affects the stability of the twist.

  In a further advantageous manner, flyer bobbins are used as feed bobbins which are fixed in the frame and whose feed material is drawn to a thread thickness which can be set by means of a drafting device (claim 15).

  Such a flyer bobbin, on the one hand, has a wound material that already has a slight twist and therefore has a certain degree of basic stability, and on the other hand a flyer bobbin is a relatively compact material model. It has the advantage that That is, the frame in which the flyer bobbin must be accommodated during the spinning process may be similarly configured to be relatively compact, which is further advantageous for the minimum size of the yarn balloon that goes around the frame during the spinning process. Act on. Similar to the configuration in the ring spinning machine, the roving bobbin is preferably arranged above the drafting device, so that the stretched sliver advances directly into the spindle downwards.

  In another aspect as claimed in claim 16, the spindle comprises a storage disk. Thereby, when the variation of the yarn tension is small, a limited yarn length can be accommodated.

  Alternatively, the draft device may be located above the supply bobbin and on the storage device for the supply bobbin so that the supply bobbin can be removed from the storage device and In this case, a new supply bobbin can be mounted without any problem (claim 17).

  According to the eighteenth aspect, the opening 36 is disposed above the draft device, and is drawn out from the supply bobbin 15 ′ through the opening and guided around the periphery of the draft device 16 while forming the yarn balloon 25A. The roving yarn 20 can be supplied to a draft device.

  The present invention will be described in detail below with reference to embodiments shown in the drawings.

1 is a front view showing a first embodiment of a double twister spinning apparatus according to the present invention. It is a figure which shows another embodiment of the double twister spinning apparatus by this invention. It is a figure which shows 3rd Embodiment of the double twister spinning apparatus by this invention. FIG. 6 is a diagram showing a fourth alternative embodiment of a double twister spinning apparatus according to the present invention.

  In different drawings, similar components are denoted by the same reference numerals. The double twister spinning device according to the present invention is indicated by the reference numeral “1” in all drawings.

  For example, as is clear from FIG. 1, the double twister spinning device 1 has a stationary machine base 2. A rotary device, preferably a spindle 5, which is formed at least partially hollow, is rotatably supported in the machine table 2, for example via rolling bearings 3, 4. In this case, the spindle 5 can be controlled and driven via, for example, an electric motor type individual drive unit 6. That is, the spindle 5 can be rotated about its axis of rotation 9 at an adjustable number of revolutions by an individual drive 6 connected to the control device 8 of the textile machine via a control line 7.

  As further shown in FIGS. 1, 2 and 3, the spindle 5 has a first axial yarn guide passage section 10 arranged in the upper spindle region. A second yarn guide passage section 11 that is branched in the radial direction is connected to the first yarn guide passage section 10 in the axial direction. Furthermore, a frame 13 is preferably supported on the spindle 5 via a rolling bearing assembly 12 as well. This frame 13 has a receiving device 14 for a supply bobbin, in particular a flyer bobbin 15, as well as a draft device 16.

  The draft device 16 has, for example, an inlet roller pair 17, an intermediate roller pair 18 and an outlet roller pair 19. In this case, the different roller pairs rotate at different rotational speeds, as is usual in drafting devices. That is, the roving yarn 20 drawn from the flyer bobbin 15 and passing through the draft device roller pair 17, 18, 19 can be stretched to a sliver thickness that can be set when passing.

  Advantageously, each drafting roller pair 17, 18, 19 has at least one roller that can be driven. That is, it has one roller provided with the drive part connected to a drive part or located inside.

  In the present embodiment, the driving rollers of the draft device roller pairs 17, 18, 19 are formed, for example, as electric motor type outer rotors. Each of the outer rotors is supplied with current and data wirelessly via an energy and data transmission device 21 as shown in FIGS. 1 and 3, or a brush as shown in FIG. Current and data are supplied via the elements 21A and 21B. In this case, the first brush element 21A is advantageously arranged below the yarn balloon 25 rotating during the spinning operation, whereas the second brush element 21B is arranged above the yarn balloon 25. ing. According to the embodiment shown in FIG. 1 and FIG. 3, the energy and data transmission device 21 includes first transmission / reception devices 22A and 22B and second transmission / reception devices 24A and 24B. In this case, these first transmission / reception devices 22A and 22B are disposed outside the balloon restricting portion 23 (FIG. 1) and thus outside the thread balloon 25, or when the balloon restricting portion is omitted. It is simply positioned outside the thread balloon 25 (FIG. 3). Furthermore, the second transmitting / receiving devices 24A, 24B are advantageously positioned on the frame 13 inside the yarn balloon 25 that rotates during the spinning operation. In both embodiments, energy and data transmission is advantageously performed electromagnetically between the transmitting / receiving devices 22A, 22B or 24A, 24B.

  Accordingly, the frame 13 disposed on the spindle 5 so as to be rotatable in itself is prevented from rotating in a force connection manner or by a magnetic force by the rotation preventing portion 26 in all the embodiments. In this case, the rotation preventing part 26 is advantageously composed of a rotation preventing magnet 27A disposed outside the balloon restricting part 23 or the thread balloon 25 and a rotation preventing magnet 27B installed on the frame 13. .

  In the embodiment shown in FIG. 3, the use of a balloon restriction is omitted, and the diameter of the yarn balloon 25 formed during the spinning process is instead adjusted based on the yarn tension present in the region of the yarn balloon 25. Is done. That is, by adjusting the yarn feed speed of the drafting device 16 in relation to the yarn transport speed of the yarn feed device 35 arranged before the winding or winding device 29, the tension of the yarn, and hence the yarn balloon 25 is adjusted. The diameter can be set.

  Furthermore, in these embodiments, a balloon thread guide 28 or 28 ′, 28 ″ is arranged in the frame 13 at the top and in the center with respect to the winding or winding device 29. In this case, the balloon thread guide 28 is rotatably supported by, for example, a rolling bearing 34 as shown in FIG.

  The balloon yarn guide arranged in the center sets the length of the yarn balloon 25 during the spinning process. The maximum diameter of the yarn balloon 25 is determined by the balloon restricting portion 23 as already described above, or is determined by the tension of the yarn in the region of the yarn balloon 25.

  However, instead of the balloon thread guide 28 rotatably supported, a balloon thread guide 28 'fixedly installed as shown in FIG. 2 or 4 is installed, or as is apparent from FIG. Balloon thread guides 28 that can be driven by individual motors may be installed. In this case, unlike the balloon thread guides 28, these thread guides are oriented in the horizontal direction, not in the vertical direction. A drivable balloon yarn guide 28 '' provides a temporary false twist to the yarn. This false twist has an advantageous effect on the stability of the twist (Spinnstabilitaet).

  One yarn delivery device 35 is installed on the downstream side of the balloon yarn guide in the yarn traveling direction F and on the upstream side of the winding or winding device 29, respectively. The yarn feeding device 35 can adjust the yarn conveyance speed, and hence the yarn tension. As usual, the winding or winding device 29 includes a means for rotating the traverse package 30 held by a package frame (not shown) and a yarn 31 that runs on the traverse package 30 during the spinning process. Means for traversing. That is, the winding or winding device 29 has an electric motor type drive unit 32 in the present embodiment. The drive unit 32 presses the traverse package tube through the curled tube plate, and in this case, the traverse package 30 rotates. Furthermore, the winding or winding device 29 is equipped with a yarn traversing device 33, which is shown only schematically in the present embodiment. The traversing device 33 may have different embodiments as suggested above.

  In this case, a particularly advantageous embodiment is a so-called finger thread guide (known and not shown in detail). The finger yarn guide not only allows for a defined adjustment of the traverse speed of the traverse yarn guide in a relatively simple manner, but also allows for simple and precise adjustment of the desired width of the traverse package 30, for example. To.

  In an alternative embodiment shown in FIG. 4, a so-called storage disk or yarn storage disc 37 is arranged on the spindle 5 '. The structural configuration of the storage disk 37 has been known for some time, for example in connection with a double twister twisting device. The storage disk 37 can accommodate a limited yarn length when the variation in yarn pulling force is small. This storage disk can be used in other embodiments as well, i.e. it is not specifically designed for this embodiment.

  The first yarn guide passage section 10 in the axial direction and the second yarn guide passage section 11 connected in the radial direction are also provided on the spindle 5 'in the same manner as in the other embodiments.

  In general, the embodiment shown in FIG. 4 differs depending on the modified arrangement of the roving bobbin 15 ′ and the drafting device 16.

  The storage disc 37 further supports the base segment 13 ′ of the frame 13, preferably via a rolling bearing assembly 12 ′, which has a receiving device 14 ′ for the supply bobbin 15 ′. doing.

  As further shown in FIG. 4, the containment device 14 ′ is arranged with a draft device 16 similar to the other embodiment in the frame portion 13 ″, in which case the draft device 16 can In some cases, it can be separated from the receiving device 14 '. The desired case is, for example, the case where the supply bobbin 15 'is fully extended and must be replaced with a new supply bobbin 15'.

  Also in this case, the energy and data transmission device 21 has a transmission / reception device, and the transmission / reception device needs to straddle the two thread balloons 25A and 25B, for example. Alternatively, wireless transmission may occur in the region of the base segment 13 'simply through the outer balloon 25B, in which case it may be transmitted by wiring or wire harness via the receiving device 14'.

  The base segment 13 ′ rotatably arranged on the storage disk 37 is prevented from rotating by a force connection type by the rotation prevention unit 26. In this case, the anti-rotation part 26 preferably comprises an anti-rotation magnet 27A arranged on the outside of the yarn balloon 25B and an anti-rotation magnet 27B arranged on the base segment 13 '.

  An opening 36 is disposed above the draft device. Through this opening 36, the coarse yarn 20 which is pulled out from the supply bobbin 15 'and guided around the draft device 16 while forming the yarn balloon 25A is supplied to the draft device 16.

  In the embodiment shown in FIG. 4, the use of a balloon restriction can be dispensed with; instead, the diameter of the yarn balloon formed during the spinning process depends on the tension of the yarn formed in the region of the yarn balloon. Adjusted.

  In other words, by adjusting the yarn unloading speed of the drafting device 16 correspondingly to the yarn conveying speed of the yarn feeding device 35 arranged before the winding or winding device 29, the tension of the yarn and thus the yarn The diameter of the balloon 25B can be set. In this case, the storage disk can also be omitted within the thread tension adjustment frame, which results in a similar configuration as in other embodiments.

  The winding or winding device 29 corresponds to another embodiment.
