Definitions
- the present invention relates to a method for processing a strand-like fiber composite, wherein the fiber strand of an air-spinneret is fed to a roving serving roving, wherein the fiber structure within the air-spinneret during normal operation of the air-spinneret with the aid of a swirling air flow is given a rotation, so that from a roving is formed in the fiber structure, and wherein the roving finally leaves the air-spinneret via an outlet of the air-jet nozzle.
- Roving machines with corresponding air-jet nozzles are known in the art and serve to produce a roving from an elongated, strand-like fiber structure.
- the air-jet nozzles comprise an internal vortex chamber and air nozzles which open into the vortex chamber and produce a vortex air flow during operation of the air-jet spinning machine inside the vortex chamber.
- the outer fibers of the fiber composite are wound around the inner core fibers by the vortex air flow in the region of the inlet mouth of a yarn formation element extending into the vortex chamber, thereby forming the binder fibers which determine the desired strength of the roving. This results in a roving with a true rotation, which is finally discharged through a vent channel from the vortex chamber and finally leaves the air-spinneret via an outlet.
- roving (other designation: sliver) is to be understood as meaning a fiber structure in which at least some of the fibers are wound around an inner core.
- This type of yarn is characterized by the fact that, despite a certain strength, which is sufficient to transport the yarn to a subsequent textile machine, it is still delayable.
- the roving can thus with the help of a defaulting device, z. B. the drafting system, a roving processing textile textile machine, such as a ring spinning machine, are warped, before finally being spun into a conventional yarn.
- the object of the present invention is to improve the known method with regard to ever faster working textile machines which are to be supplied with the roving.
- the method for processing a strand-like fiber composite is now characterized in that the roving leaving the air-spinning nozzle is deposited in or on a receptacle which is provided in the area of the roving machine.
- the roving is therefore not wound onto a sleeve to form a coil. Rather, there is a loose storage in or on the recording, from which it can be removed and further processed after the transport of the recording to a subsequent textile machine.
- the receptacle is preferably a container, particularly preferably an upwardly open receptacle, as is known in spinning mills, which is generally referred to as a spinning can.
- the sliver can here in a plan view round or elongated, for example, rectangular, be formed. With regard to possible shapes, reference may be made, for example, to DE 10241011 A1 or DD 232246 A1, the shape of the container being of secondary importance for the present invention. It is also conceivable, however, that the receptacle is formed only as a flat portion without side walls on which the roving during storage, for example heap-shaped, is stored. The recording can therefore z. B.
- the receptacle is designed as a container which has a volume of at least 0.05 m 3 , preferably at least 0.1 m 3 .
- the roving deposited according to the invention can also be passed on to textile machines which have a high consumption of rovings.
- correspondingly filled containers are excellently suitable as a template for a conventional borrowed air-jet spinning machine at which several hundred meters of yarn per minute are produced per spinning station.
- the roving is deposited in or on the receptacle such that the roving has an average density of at least 0.14 g / cm 3 , preferably of at least 0.15 g / cm 3 , particularly preferably of at least 0, after complete filling of the receptacle , 16 g / cm 3 .
- the take-off device may, for example, comprise two corresponding take-off rollers driven by means of a drive, between which the roving is guided in a clamping manner after leaving the air-jet nozzle and directed in the direction of the take-up.
- the roving After passing through the drawing-off device, the roving preferably finally reaches the area of a storage device, is grasped by it and placed in or on the holder.
- the storage device ensures that the roving passes in a defined and controlled manner in or on the recording, so that knots or for the subsequent removal of the roving of the recording unfavorable and undefined overlaps of the roving are avoided.
- the roving is placed in the form of a loop in or on the receptacle with the aid of the draw-off device, wherein the loops can have a circular or oval shape at least in sections.
- the storage device preferably comprises a storage tray with a storage channel, through which the roving is passed during storage, wherein the storage tray is preferably placed during the storage of the roving by means of a drive in a rotary motion.
- a turntable may be present, on which the receptacle is located during storage and which is driven during the storage of the roving with a drive (where the drive may be the same drive, which also drives the storage tray, so that both plates can be driven synchronously).
- the tray and / or the turntable can also be driven by means of a drive which causes a non-rotational movement of the corresponding turntable and / or the tray.
- a drive which causes a non-rotational movement of the corresponding turntable and / or the tray.
- another movement element could be provided on which the receptacle is parked or otherwise held during storage of the roving and which is moved on a path of motion consisting of or including individual linear or curved sections to avoid unwanted movement Turning the roving to avoid its longitudinal axis during storage.
- the recording can be moved exclusively or partially translationally.
- the receptacle is rotated alternately in a first and an opposite second direction.
- the recording could be alternately rotated by 360 ° clockwise and then by the same amount counterclockwise to avoid unwanted rotations of the deposited roving.
- two storage plates could be present, which deposits the roving of two juxtaposed air spinnerets in or on a common recording.
- the storage tray could turn in this case alternately in opposite directions, with an angular range of 180 ° would be beneficial.
- the take-off device and the depositing devices, which guide the roving through direct contact.
- one or more sensors can be arranged between the take-off device and the depositing device, which monitor or monitor the roving on its quality (thickness, hairiness, etc.), if any roving emerges from the air-jet nozzle and / or reaches the area of the depositing device or to monitor the course of the roving.
- the roving between the take-off device and the storage device forms a slack whose vertical spatial extent is regulated by the storage speed of the storage device.
- the roving describes a parabola between the air-jet nozzle or the removal device and the storage device or one of these upstream guides (eg a guide roller). If the vertical spatial extent exceeds or reaches a predetermined maximum value, the deposition speed is increased. If the vertical spatial extent falls short of a predetermined minimum value, the deposition speed is reduced, whereby the speed of the deposition is increased or reduced, for example by changing the rotational speed of the deposition plate and / or the turntable and wherein the change is preferably by control of the roving machine is done automatically.
- the guide may for example be designed as a conveyor belt or as an elongated channel, wherein one or more nozzles could be present, which are in communication with a compressed air supply to lead the roving by means of compressed air in the direction of the storage device or to move through the guide can.
- the nozzles can also serve as a threading aid through the air flow emanating from it in order to move the roving into or onto the guide after leaving the draw-off device or the air-spinning nozzle.
- the normal operation of the roving machine (during which roving is produced and stored in or on the recording) is interrupted by stop phases, in which no roving is produced by the air-jet nozzle.
- Reasons for this are, for example, ripping of the roving, a problem in the supply of the fiber composite or clogging of the air-spinneret.
- a start phase is run through between such a stop phase and the subsequent normal operation.
- the starting phase is characterized in that the preparation of the roving is resumed, wherein during the starting phase, the roving produced by the air spinning nozzle after leaving the air spinneret at least temporarily not stored in or on the recording, but is disposed of via a roving.
- the roving removal may, for example, be a suction element subjected to negative pressure (eg a suction pipe).
- a suction element subjected to negative pressure eg a suction pipe.
- the roving discharge may be deactivated or bypassed (eg by a switch which influences the course of the roving) so that the subsequently produced roving into or onto the receiver whereby the roving entering or leaving the receptacle is separated from the withdrawn roving section (in order to avoid that this ultimately ends up in or on the receptacle).
- a recording change operation is performed when, when the recording has reached a defined degree of filling or when a defined Vorgarnmenge or Vorgarnin produced by the Lucasspinndüse and was stored in or on the recording.
- the amount of roving or length of roving or the degree of filling mentioned can be monitored by means of one or more sensors. In any case, after the corresponding setpoint values have been reached, the recording filled up to this point will be replaced by an empty recording.
- the change process can in this case be carried out automatically by means of a recording change device of the roving or manually by an operator.
- the production of the roving is not stopped during the pick-up change process. In other words, so should during the intake change process roving be produced by the air-spinning machine.
- the produced roving is thus stored before the recording change process in or on a first recording.
- the roving tray is finally moved into or onto the second receptacle, the corresponding receptacles being displaced under the air-spinning nozzle which is always remaining at the same location (for example by the above-mentioned pick-up device).
- An existing after the recording change process between the two images Vorgarnschleife must finally be severed in order to remove the full shot regardless of filling the new recording of the roving.
- the roving produced by the air-spinning nozzle during the pick-up change process is disposed of at least in sections via a roving discharge.
- the roving is thus produced continuously during the pick-up change process, passes here before the pick-up change operation in or on a first pickup and after or already during the pick-up change operation in or on a second pick-up.
- the removal of the roving leaving the air-spinning nozzle takes place via the roving discharge, wherein the roving section located in or on the first holder is previously separated off.
- the roving leaving the air-jet nozzle is finally returned to the depositing device, which deposits the roving in or on the above-mentioned second receptacle.
- the amount of roving produced per unit time by the air-jet nozzle during the pick-up operation or during the time the roving is disposed of through the roving discharge is at least temporarily restricted from normal operation to minimize the amount of disposed roving.
- the production of the roving is temporarily interrupted during or before the pick-up change process. This can be done either by stopping the supply of the fiber dressing in the air-spinneret or the interruption of the air supply thereof. In any case, the roving production stops. If the previously filled image has been replaced by an empty image, then can be continued with the Vorgarnher too again, it is in principle advantageous if the storage device already in motion, z. B. in rotation, is added before the roving reaches the storage device.
- the recording is moved after its partial or complete filling with roving to one of the production of conventional yarn serving air-spinning machine, wherein the present in or on the recording roving is spun by means of the air-spinning machine into a yarn.
- the filled receptacle thus serves as a template for the air-spinning machine, which also produces a conventional yarn from the roving with the aid of a swirling air flow, which yarn can finally be made into a fabric, for example with the aid of a weaving machine.
- Corresponding air spinning machines are well known in the art and usually include a plurality of spinning stations, each with a drafting device for warping the roving, a downstream Heilspinndüse to give the desired rotation and thus for the production of the yarn and a winding unit for winding the Lucasspinndüse leaving yarn.
- the receptacle is moved to a spinning knitting machine serving to make a knit fabric, a knitted fabric being produced from the roving present in or on the receptacle with the aid of the spinning knitting machine.
- a spinning knitting machine usually also includes a drafting system for warping the roving.
- a swirl unit which causes the warped roving to rotate slightly. divides, so that it can be transported to a knitting unit of the spinning knitting machine.
- the knitting unit finally processes the warped roving into a knit fabric.
- the knitting unit of the spinning knitting machine can be located a few centimeters to several meters away from the swirl unit. If this distance is above a predetermined maximum value, it may be advantageous to equip the material with one or more filaments, wherein the filament can be introduced into the material flow in the area of the drafting system or the swirl unit and thus a kind of core yarn arises.
- the roving machine according to the invention is finally distinguished by the fact that it comprises at least one depositing device, by means of which the roving leaving the air-spinning nozzle, preferably loop-shaped, can be placed in or on a receptacle.
- the roving leaving the air-spinning nozzle preferably loop-shaped
- individual or all of the previously mentioned or subsequently mentioned physical features, such as the trigger device be realized.
- the roving machine comprises a controller or is in communication with a controller which is designed to operate the roving machine according to the previous or following description.
- Figure 2 is a sectional view of a section of an air-spinneret of a roving machine according to the invention.
- Figure 3 selected elements of another roving machine according to the invention in side view and a plan view of a trained as a holding receptacle with roving.
- FIG. 1 shows a schematic side view of a prestressing machine according to the invention. (only selected elements which are relevant for the understanding of the invention are shown, the same also applies to the remaining figures).
- the roving frame can comprise a drafting system with a plurality of drafting rollers 15 rotatable about an axis of rotation (only two of the six drafting rollers 15 are provided with a reference numeral), the drafting system being provided with a fiber structure 1, for example in the form of a fiber composite, during the spinning operation doublierter strip, is supplied.
- the roving frame shown comprises one or more adjacent air spinnerets 2, each with an internal swirl chamber 23 (see Figure 2), in which the fiber structure 1 or at least a part of the fibers of the fiber composite 1 is provided with a rotation (the exact mode of action of Spinneret will be described in more detail below).
- the roving machine may comprise a take-off device 6, preferably with several cooperating take-off rollers 16, with the aid of which the roving 3 leaving the spinneret via its outlet 4 is grasped and guided
- the take-off rolls 16 are preferably set in a rotary motion by means of a drive, not shown).
- the roving machine according to the invention need not necessarily have a drafting device, as shown in Figures 1 and 3. Also, the take-off rollers 16 are not absolutely necessary. In any case, the roving machine according to the invention operates according to an air spinning method. To form the roving 3, the fiber structure 1 is guided via an inlet 13 of the air-jet nozzle 2, in which preferably a so-called fiber guide element 14 is arranged, into the swirl chamber 23 of the air-spinning nozzle 2 (see also FIG. 2).
- the produced roving 3 is a yarn with a relatively small proportion of binding fibers, or a yarn in which the binding fibers are wound relatively loosely around the inner core, so that the Roving 3 remains delayable.
- a subsequent textile machine for example, a conventional air spinning machine
- the produced roving 3 on a subsequent textile machine must be warped again with the help of a drafting system to be processed into a conventional yarn, which can be processed for example on a loom to a fabric.
- the present invention now proposes to deposit the roving 3 loosely after leaving the air-spinneret 2 in a receptacle 5 designed as a container, wherein in this case preferably the spinning cans known in spinning mills can be used.
- the roving machine for this purpose has a storage device 7 which encompasses at least one storage tray 18.
- the storage tray 18 is displaceable by means of a drive, not shown, in a rotational movement in order to store the originating from the air-spinneret 2 roving 3 loop-shaped in the receptacle 5 can.
- the storage device 7 may also have one shown in FIG Have turntable 19, by means of which the receptacle 5 can be set in a rotary motion.
- the roving 3 can be fed either directly to the storage tray 18 or its inner and helical storage tray 21 after leaving the removal device 6 (FIG. 1). It is also conceivable, however, that the roving 3 initially forms a sag 8 and then the storage tray 18 is fed, wherein between storage tray 18 and withdrawal device 6, one or more sensors 17 and or an additional guide 20, z. B. in the form of a leadership role, may be present.
- the sensor (s) 17 monitor the vertical extent of the slack 8, wherein a control, not shown, based on the readings of the sensor or sensors 17, as described above, regulate the rotational speed of the turntable 19 and / or the tray 18 to determine the vertical extent in FIG to keep a defined area.
- FIG. 1 shows that it can be advantageous if the roving machine has a roving discharge 9, for example in the form of a suction tube. If now started with the Vorgarnher too, so there is initially a start phase, during which the air-spinneret 2 leaving roving 3 is detected by the roving 9 and disposed of. If the quality of the roving 3 finally complies with the specifications, the roving discharge 9 can be deactivated and the roving section already removed by the roving discharge 9 is separated from the roving section by means (not shown) (eg a cutting unit), which is now separated from the roving section Air spinneret 2 is produced.
