Definitions
- the invention relates to a spinning apparatus and a method for spinning a spinning apparatus for the continuous extrusion of moldings from a spinning solution, and a piecing apparatus for performing the method, wherein the moldings are extruded as loose spinning curtain from the spinning solution through spinning nozzles of the spinning device, the shaped body of the loose spinning curtain after extrusion to form a shaped body bundle, and the shaped body bundle is fed in a further step a trigger member of the spinning device to start a continuous extrusion of the shaped body.
- Spinning devices of the type mentioned and the spinning process carried out therewith are known from the prior art for the production of moldings, for example fibers, filaments, films, etc.
- said processes are used to produce spun staple or continuous fibers.
- the spinning solution is pressed through a plurality of spinnerets.
- the extruded molded articles Before the further treatment of the extruded molded articles in subsequent process steps, such as washing, pressing, drying, etc., which do not take place in the spinning device itself, the extruded molded articles must be continuously transported out of the spinning device, for example via a take-off element. To be able to feed the moldings to such a take-off device, they first have to be combined into a bundle.
- the spinning of the spinning device is a first process section of a spinning process, which is intended to enable or initiate a continuous extrusion of moldings in the spinning process.
- the piecing process therefore comprises all the process steps of a spinning process which are necessary between the end of a first continuous extrusion and a subsequent continuous extrusion, for example after the spinning device has come to a standstill or after spinning defects such as the tearing off of some shaped bodies below the spinnerets have occurred.
- a spinning device of the type mentioned wherein the extruded from the spinneret spinning curtain is passed through a bottom opening of the Spinnbad materialsers.
- the bottom-side opening acts reducing the diameter of the spinning curtain, whereby the shaped bodies are combined to form a shaped body bundle.
- the piecing and the manipulation of the spinning curtain are made much more difficult by the very high depths of the Spinnbad employer disclosed therein.
- Such spinning devices therefore suffer from the low reproducibility of the piecing process as well as the high susceptibility to piecing defects, which do not permit satisfactory continuous extrusion of the shaped articles and often necessitate re-spinning.
- Spinning devices for facilitating the piecing process are also known from the prior art. That's how it shows EP 0 574 870 A1 a spinning device in which the extruded moldings are summarized after exiting the spinneret as a spinning curtain to a shaped body bundle.
- This is achieved by the use of a spinning funnel in the spinning bath of the spinning bath container, which narrows down in cross-section and has a lower narrowed outlet opening. If the spinning curtain is guided through the spinning funnel, a shaped body bundle is created on exit of the shaped body from the spinning funnel, thus facilitating further handling of the shaped bodies in the spinning device during piecing.
- such spinning funnels are disadvantageously arranged deep in the spin bath container, whereby a simple handling by the operator is not given.
- the EP 0 746 642 B1 describes to overcome the aforementioned disadvantages, a spinning device, wherein a bundling element is provided for bundling the shaped body in the form of a deflecting element in Spinnbad hereer.
- a bundling element is provided for bundling the shaped body in the form of a deflecting element in Spinnbad hereer.
- the piecing is thereby made significantly more difficult because an initial, manual bundling of the curtain to a shaped body bundle by the operator is necessary to provide the molded body in the deflection.
- this disadvantageously requires a lot of effort by the operator.
- such a piecing process is very susceptible to piecing defects, especially to incomplete bundling of the spinning curtain.
- the present invention has therefore set itself the task of designing a piecing method of the type described above procedurally simple and reproducible.
- the invention achieves the object with regard to the piecing process in that the shaped bodies are combined by torsion of the spinning curtain around a torsion axis to form the shaped body bundle.
- the continuous extrusion of the shaped bodies and the bundling into a homogeneous shaped body bundle can be significantly improved, which is particularly beneficial for the reliability of the piecing process.
- the individual shaped bodies are rotated about a common point of contact with each other, so that the compact shaped body bundle is formed at the point of contact.
- the torsion of the spinning curtain so the rotation of the individual moldings around the common point of contact, can also be particularly advantageous for a low error rate in the bundling of the moldings act as reliable almost all moldings can be summarized in the bundle. This can also be done with much less effort.
- the torsion of the spinning curtain can overcome these disadvantages, in particular not only a compact shaped body bundle is created, but the torsion can also ensure a continuous, well controllable removal of the moldings from the spinnerets, which reliably prevent damming of the moldings and a swelling of the spinning curtain can.
- a particularly simple and reliable process for piecing a spinning device can thus be provided. This leads advantageously also subsequently to a more uniform and stable spinning process.
- the invention may also be particularly distinguished when the spinning process is a lyocell process, and the shaped bodies are cellulosic shaped bodies, in particular cellulosic fibers, which consist of a spinning solution containing water, cellulose and tertiary amine oxide through spinnerets the spinning device are extruded.
- the torsion of the spinning curtain can in fact already take place in the air gap between spinnerets and spinning bath, whereby a better accessibility and thus a much simpler process is created.
- the torsion of the spinning curtain to the shaped body bundle can be particularly easily done when the torsion axis is substantially parallel to the extrusion direction of the extruded molded body. If the torsion axis also passes through the center of the spinning curtain, it can be ensured that the torsion of the spinning curtain acts uniformly and symmetrically on all shaped bodies. A particularly homogeneous shaped body bundle without internal stresses can thus be created in the course of piecing, which can further reduce the tendency to piecing errors. A particularly reliable and reproducible piecing method can thus be provided.
- the speed of torsion of the spinning curtain can be adapted and tuned by the rotational speed of the torsion means to the required parameters of the spinning device, thus ensuring particularly stable spinning conditions during piecing.
- the desired take-off speed of the shaped bodies from the spinning nozzles and thus the desired molded body properties can be adjusted by the rotational speed of the rotating apparatus, which can reliably prevent the formation of spinning defects.
- the reproducibility of the piecing process can thus be further increased.
- the use of a rotary device to twist the spinning curtain can contribute to the physical relief of the operator of the spinning device, which further simplifies the implementation of the method.
- the operators of the spinning device can be significantly relieved, especially in the initial phase of piecing. This is especially true when the torsion means of the rotary device is accelerated step by step in its rotational speed until a final speed is reached after the ends of the moldings have been deposited. Likewise, it is also conceivable that the rotational speed is accelerated continuously after storage of the molded body. In addition, it is noted that the acceleration of the torsion can be done in linear or non-linear acceleration profiles to optimize the torsion of the moldings according to their properties.
- the method according to the invention can therefore be characterized by a lower tendency to piecing errors and by the fine motor and physical relief of the operator, as well as by high reproducibility.
- the torsion means is formed by a rotatable turntable and the axis of rotation of the turntable runs essentially parallel to the extrusion direction of the shaped bodies.
- the torsion of the spinning curtain can be made even more reliable if the ends of the moldings adhere to holding elements of the turntable.
- the holding elements can in fact take with the rotation of the turntable, the ends of the moldings in their rotational movement and rotate the moldings around a common point of contact in the spinning curtain around each other and thus cause the torsion of the spinning curtain.
- an attack region on the shaped body bundle is created by the torsion of the spinning curtain, a particularly advantageous and simple handling of the shaped body bundle can be made possible in the piecing process.
- an attack area on the shaped body bundle this can namely be manipulated and processed further simply and reliably in subsequent method steps.
- the automated, mechanical handling and manipulation of the shaped body bundle is made possible by the defined attack area. If the attack area is also created in the region of the smallest diameter of the twisted shaped-body bundle, a particularly reliable handling of the shaped-body bundle can be achieved.
- the area of the smallest diameter of the shaped-body bundle is essentially at the vertex of the spinning curtain, whereby a simple, in particular machine recognizability of the attack area, for example for fully automatic manipulation of the shaped-body bundle, is provided.
- a particularly simple piecing method can be created if an automatic gripping device grips the shaped body bundle and feeds it to the take-off element of the spinning device.
- An automatic gripping device can be about be a gripper on a manipulator arm, which automatically grips the shaped body bundle after torsion, transported via displacement of the manipulator arm to the trigger and it provides in the trigger member (such as by clamping, clamping, fastening, etc.).
- the gripping device advantageously engages the shaped body bundle on the trained attack area and can thus ensure a high process reliability.
- the method can have a particularly advantageous effect if the shaped-body bundle is provided in the draw-off element only after reaching a terminal speed of the rotary device.
- the final speed of the rotary device can be determined by the desired molding properties or by the required take-off speed of the moldings from the spinnerets.
- the manipulator arm which provides the shaped body bundle in the take-off member, should advantageously be matched to the extrusion of the shaped bodies, in particular to the withdrawal speed of the shaped bodies, both in terms of movement speed and movement profile.
- the piecing process can be further made more reliable if the shaped body bundle is cut off after being gripped by the automatic gripping device.
- the shaped body bundle is trimmed below the engagement region, so that the lower part of the shaped body bundle deposited on the rotating device is severed. The feeding of the trimmed shaped body bundle to the trigger member can thus be significantly facilitated.
- the invention also relates to a piecing device for piecing a spinning device, comprising a bundling device for bundling molded articles extruded from the spinning nozzles of the spinning device, which bundling device has a rotating device with at least one means rotatable about a rotation axis, wherein the rotatable means is designed such that the shaped articles be summarized via the means to the shaped body bundle.
- the invention has therefore further set itself the task of improving a piecing device of the type mentioned above in that the method for piecing the spinning device - in particular the bundling of the spinning curtain into a shaped body bundle - be performed using the piecing easily and reproducibly and with little effort can.
- the invention solves the problem with regard to the piecing device in that the rotatable means is designed as a torsion means, in particular as a turntable, for torsion of the shaped bodies and the axis of rotation of the torsion means is substantially parallel to the extrusion direction of the shaped bodies.
- the piecing device has a bundling device for bundling the extruded shaped bodies to form a shaped body bundle, and if the rotatable means is designed as a torsion means for torsion of the shaped bodies and if the axis of rotation of the torsion means is substantially parallel to the extrusion direction of the shaped bodies, a particularly stable and simple piecing apparatus can be used a spinning device can be provided, which can further simplify a method for piecing the spinning device on.
- the rotation device with the torsion means may be formed in particular for receiving ends of the extruded molded bodies from the loose spinning curtain, so that the ends of the shaped bodies can be deposited on the torsion means and a torsion of the spinning curtain is generated via the rotational movement of the torsion.
- the rotational movement of the torsion means and associated torsion of the spinning curtain to a shaped body bundle can thus replace the difficult step of bundling the shaped body by a structurally particularly simple device.
- the torsion means is designed as a turntable, the torsion of the extruded shaped bodies can take place in a structurally particularly simple manner. This is especially true when the turntable is substantially parallel to the Extrusion direction of the extruded from the spinnerets molded body is rotatable. Namely, a rotary device for torsion of the existing loose extruded moldings loose spinning curtain can be created about a torsion axis parallel to the extrusion direction of the moldings, which can produce particularly stable and reliable a compact moldings bundle. The reliability and stability of the spinning device can thus be further increased overall.
- the torsion means for torsion of the extruded shaped bodies is formed around a common torsion axis and the torsion axis of the shaped bodies coincides with the axis of rotation of the torsion means.
- the spinning device according to the invention may be particularly suitable for spinning a spinning device for the extrusion of cellulosic moldings from a spinning solution containing water, cellulose and tertiary amine oxide.
- the piecing device can be further increased in its reliability if the torsion means holding elements to increase the adhesion between moldings and torsion means. This in particular if the holding elements are designed as hooks.
- the piecing device additionally has at least one manipulator arm and at least one end effector on the manipulator arm, wherein at least one end effector forms the bundling device, then a sturdy spinning device can be created, which enables simple and reproducible piecing.
- the piecing device can in particular perform the piecing of the spinning device fully automatically to relieve the operator of the spinning device physically and motorically. While in the aforementioned, known spinning devices, a large amount of force is necessary to provide the spinning of the spinneret extruded molding bundles in a trigger member of the spinning device when piecing, the operator can be greatly relieved by the relatively small amount of force required in the spinning device according to the invention.
- the spinning device according to the invention can be characterized by a particularly simple handling and high security in the operation.
- the handling of the spinning device can be further simplified if the piecing device has a first manipulator arm with a first end effector wherein the first end effector has a gripper for gripping a shaped body bundle.
- the gripper on the first manipulator arm can be designed in such a way that it can reliably grasp the shaped body bundle and supply it to a take-off element of the spinning device.
- the transport of the shaped body bundle from the spinnerets to the take-off member can take place by displacing the first manipulator arm, in particular along freely selectable trajectories in space. It can be dispensed with in a method for piecing the spinning device to the relatively physically demanding and difficult to reproduce steps of manual threading of the molding bundle. This not only represents a special physical relief for the operators of the spinning device, but also can greatly contribute to increasing the safety against operating errors of the spinning device.
- the piecing device has a second manipulator arm with a second end effector, wherein the second end effector has the bundling device
- a particularly flexible piecing device with a bundling device can be provided, which bundling device is thus displaceable between a use position and a rest position if required.
- the piecing device can therefore respond flexibly to the requirements of the method: for example, the bundling device can be displaced when not in use in a rest position and thus undesirable obstructions are avoided by the bundling device in the spinning device.
- the rotary device can thus be moved in and out between spinnerets and spin bath containers.
- a more reliable spinning device can be provided herewith.
- a structurally simple bundling device can also be created when it is formed by the rotary device.
- the handling of the shaped body bundle by the piecing apparatus can be further improved if the piecing apparatus also has a cutting device for cutting off the shaped body bundle.
- the cutting device can be provided on the first manipulator arm and in particular be operatively connected to the gripper in such a way that the cutting of the shaped body bundle takes place automatically after a successful gripping operation of the gripper.
- the invention has also set itself the task of making a spinning device of the type mentioned more reliable and to facilitate the piecing of the spinning device.
- the invention solves the problem by a spinning device for the continuous extrusion of moldings, in particular for the extrusion of cellulosic moldings from a spinning solution containing water, cellulose and tertiary amine oxide, comprising at least one Spinnbadcieer Spinnbad variouser, the Spinnbad variouser associated spinnerets for extrusion of the moldings from the spinnerets in the Spinning bath with a piecing device for spinning the spinning device according to one of claims 9 to 14.
- a rotating device with a rotatable torsion means may also be distinguished according to the invention if it is used to bundle shaped articles extruded from the spinning nozzles of a spinning device by torsion of these shaped articles by means of the torsion means into a shaped body bundle.
- the torsion means may be about a turntable.
- the axis of rotation of the torsion means is substantially parallel to the extrusion direction of the extruded molded body.
- the aforementioned rotary device may be distinguished when it is used to carry out the piecing process according to the invention as claimed in claims 1 to 8.
- a spinning device 1 is shown at different stages of piecing.
- Fig. 1 shows the spinning device 1 with the loose spinning curtain 2 of extruded moldings 3 before piecing, ie before the moldings 3 were combined in a bundling device 5 to form a shaped body bundle 4, as shown in Fig. 2 is apparent.
- the spinning apparatus 1 further comprises a spinning solution 6, which are extruded through a plurality of spinnerets 7 to the moldings 3.
- the spinning solution 6 is preferably a solution containing water, cellulose and a tertiary amine oxide.
- Below the spinnerets 7 a Spinnbad consideringer 8 is provided, which contains a spinning bath 9.
- Spinning bath 9 is preferably a mixture of water and a tertiary amine oxide.
- Fig. 4 again shows the spinning device 1 after piecing.
- the shaped bodies 3 are thus combined by the bundling device 5 into a shaped-body bundle 4, and the shaped-body bundle 4 is conveyed continuously by a take-off element 10 of the spinning device 1, whereby a continuous extrusion of shaped bodies 3 from the spinning nozzles 7 takes place.
- the spinning device 1 has a piecing device 11 for carrying out the method for piecing the spinning device 1, wherein the piecing device 11 has a bundling device 5, a first manipulator arm 12 and a second manipulator arm 13.
- a first end effector 14 is provided, which end effector 14 is designed as a gripper 16.
- the gripper 16 is designed such that it can frictionally enclose and grip the shaped body bundle 4.
- the gripper 16 is also movably and controllably connected to the first manipulator arm 12. In conjunction with the free mobility of the manipulator arm 12, the gripper 16 can move the gripped molding bundle 4 along almost any trajectory.
- the piecing device 11 also has a rotary device 17, which causes the torsion of the molded body 3 in the loose shaped body curtain 2.
- the Rotation device 17 has for this purpose a rotatable torsion means 18, which is preferably designed as a turntable 31, wherein the torsion means 18 and the turntable 31 is provided as an end effector 15 on the second manipulator arm 13 and assumes the function of the bundling device 5.
- the axis of rotation 19 of the torsion means 18 and thus the torsion axis 20 of the spinning curtain 2 runs in particular parallel to the extrusion direction 32 of the shaped bodies 3 in the loose spinning curtain 2.
- Fig. 5 In order to ensure reliable torsion of the spinning curtain 2, holding elements 24 in the form of hooks 25 are provided on the torsion means 18, or in particular on the turntable 31.
- the shaped body ends 23 can thereby reliably adhere to the hook 25 and put the spinning curtain 2 in torsion via the rotational movement of the torsion means 18.
- the torsion means 18 as bundling device 5 can be extended and retracted by means of the second manipulator arm 13 between the spinnerets 7 and the spin bath container 8, whereby the bundling device 5 can be displaced from a rest position 21 into a use position 22 as required.
- the bundling device 5 can remain during the continuous extrusion of the molded body 3 in the rest position 21 and pose no obstacle between spinneret 7 and spin bath 8. If a re-spinning of the spinning device 1 is necessary, the bundling device 5 can be moved into the position of use 22 and enable a piecing process according to the invention.
- Fig. 1 shows the spinning device 1 in the first process step of piecing.
- the moldings 3 are extruded as a loose spinning curtain 2 from the spinnerets 7.
- the mold body ends 23 adhere to the holding elements 24, or hooks 25, of the torsion means 18 designed as a turntable 31 and thus increase the adhesion between mold body 3 and torsion means 18, so that undesired sliding of the mold bodies 3 on the torsion means 18 is prevented.
- the torsion means 18 is Preferably, at the beginning of the process at a standstill, but can also be placed on the torsion means 18 in rotation before the impact of the mold body ends 23. After the impact of the mold body ends 23 on the torsion means 18, the rotational speed of the torsion means 18 is increased until a predetermined final speed is reached. This can be done gradually or continuously according to a predetermined acceleration profile.
- the spinning curtain 2 is twisted about the torsion axis 20, which preferably runs parallel to the extrusion direction 32 of the shaped bodies 3 and through the center of the spinning curtain 2.
- the final speed of the torsion means 18 of the rotary device 17 determines the desired take-off speed of the shaped bodies 3 from the spinning nozzles 7 for the piecing process and thus, for example, the desired fiber titer during piecing.
- the diameter of the shaped body bundle 4 can be influenced by the rotational speed.
- diameter 28 of 1 to 20 cm, or in particular of 3 to 12 cm, has been found to be particularly preferred since such diameters 28 allow a simple and reliable handling of the shaped body bundle 4 by a gripper 16.
- an engagement region 29 is created on the shaped-body bundle 4, which is preferably located in the region of the smallest diameter 28 of the shaped-body bundle 4.
- the torsion of the spinning curtain 2 also leads to the formation of a vertex 30 on the twisted curtain 2, wherein the smallest diameter 28 of the molding bundle 4 is located substantially at the vertex 30.
- Fig. 2 is the spinning device 1 according to Fig. 1 shown after the torsion means 18 is displaced over the second manipulator arm 13 from its rest position 21 into its position of use 22 and this was positioned between spinneret 7 and spin bath 8.
- the spinning curtain 2 was then produced as described above in a second method step by the rotation of the torsion means 18 and thus the shaped body bundle 4 is created.
- Fig. 3 Furthermore, the spinning device 1 is shown after the shaped body bundle 4 was generated by torsion of the spinning curtain 2.
- the shaped body bundle 4 is now gripped by the gripper 16 on the first manipulator arm 12 of the piecing device 11 in order to subsequently provide the shaped body bundle 4 in a take-off element 10 of the spinning device 1.
- Fig. 4 This represents the last step in the process, wherein first the shaped body bundle 4 reliably held by the gripper 16 is guided by means of the first manipulator arm 12 through the spinning bath 9 around a deflecting member 26 in the spinning bath container 8. Subsequently, the shaped body bundle 4 is again led out of the spinning bath 8 and in the trigger member 10, which consists in particular of a series of withdrawal godets 27, threaded together. After threading the molding bundle 4 in the drawing-off member 10, a continuous extrusion of the moldings 3 from the spinning nozzles 7 is possible and the piecing process is thus successfully completed.

Insbesondere in der Textilindustrie werden genannte Verfahren zur Herstellung von gesponnenen Stapel- oder Endlosfasern verwendet. Zur Extrusion der Formkörper wird dabei die Spinnlösung durch eine Vielzahl von Spinndüsen gedrückt.Spinning devices of the type mentioned and the spinning process carried out therewith are known from the prior art for the production of moldings, for example fibers, filaments, films, etc. In particular in the textile industry, said processes are used to produce spun staple or continuous fibers. For extrusion of the moldings while the spinning solution is pressed through a plurality of spinnerets.
Vor der weiteren Behandlung der extrudierten Formkörper in nachfolgenden Verfahrensschritten, wie beispielsweise Waschen, Pressen, Trocknen, etc., welche nicht in der Spinnvorrichtung selbst erfolgen, müssen die extrudierten Formkörper beispielsweise über ein Abzugsorgan kontinuierlich aus der Spinnvorrichtung heraustransportiert werden. Um die Formkörper einem solchen Abzugsorgan zuführen zu können, müssen diese zunächst zu einem Bündel zusammengefasst werden.Before the further treatment of the extruded molded articles in subsequent process steps, such as washing, pressing, drying, etc., which do not take place in the spinning device itself, the extruded molded articles must be continuously transported out of the spinning device, for example via a take-off element. To be able to feed the moldings to such a take-off device, they first have to be combined into a bundle.
Im Allgemeinen wird erwähnt, dass dieser erste Teil eines Spinnverfahrens als Anspinnverfahren bzw. Verfahren zum Anspinnen ("spin-up", "lace-up") einer Spinnvorrichtung bezeichnet wird. Das Anspinnen der Spinnvorrichtung stellt einen ersten Verfahrensabschnitt eines Spinnverfahrens dar, welcher eine kontinuierliche Extrusion von Formkörpern im Spinnverfahren ermöglichen bzw. initieren soll. Das Anspinnverfahren umfasst demnach alle Verfahrensschritte eines Spinnverfahrens, welche zwischen dem Ende einer ersten kontinuierlichen Extrusion und einer nachfolgenden kontinuierlichen Extrusion notwendig sind, beispielsweise nach einem Stillstand der Spinnvorrichtung oder nachdem Spinnfehler, etwa das Abreißen einiger Formkörper unterhalb der Spinndüsen, aufgetreten sind.In general, it is mentioned that this first part of a spinning process as a spin-on process or "lace-up" of a Spinning device is called. The spinning of the spinning device is a first process section of a spinning process, which is intended to enable or initiate a continuous extrusion of moldings in the spinning process. The piecing process therefore comprises all the process steps of a spinning process which are necessary between the end of a first continuous extrusion and a subsequent continuous extrusion, for example after the spinning device has come to a standstill or after spinning defects such as the tearing off of some shaped bodies below the spinnerets have occurred.

Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, ein Anspinnverfahren der eingangs beschriebenen Art verfahrenstechnisch einfacher und reproduzierbarer zu gestalten.The present invention has therefore set itself the task of designing a piecing method of the type described above procedurally simple and reproducible.
Die Erfindung löst die Aufgabe hinsichtlich des Anspinnverfahrens dadurch, dass die Formkörper durch Torsion des Spinnvorhangs um eine Torsionsachse zu dem Formkörperbündel zusammengefasst werden.The invention achieves the object with regard to the piecing process in that the shaped bodies are combined by torsion of the spinning curtain around a torsion axis to form the shaped body bundle.
Werden die Formkörper durch Torsion des Spinnvorhangs um eine Torsionsachse zu dem Formkörperbündel zusammengefasst, so kann die kontinuierliche Extrusion der Formkörper und die Bündelung zu einem homogenen Formkörperbündel deutlich verbessert werden, was der Zuverlässigkeit des Anspinnverfahrens besonders zuträglich ist. Bei der Torsion des Spinnvorhangs werden die einzelnen Formkörper um einen gemeinsamen Berührungspunkt miteinander verdreht, so dass am Berührungspunkt das kompakte Formkörperbündel entsteht. Die Torsion des Spinnvorhangs, also das Verdrehen der einzelnen Formkörper um den gemeinsamen Berührungspunkt, kann zudem besonders vorteilhaft für eine geringe Fehlerquote bei der Bündelung der Formkörper wirken, da zuverlässig nahezu alle Formkörper in dem Bündel zusammengefasst werden können. Dies kann zudem unter deutlich geringerem Kraftaufwand erfolgen. Bei den aus dem Stand der Technik bekannten Verfahren zum Anspinnen von Spinnvorrichtungen kann es außerdem durch ungenügend schnellen Abtransport der Formkörper nach deren Extrusion aus den Spinndüsen insbesondere zu einem Aufstauen der Formkörper und damit zum einem Aufblähen des Spinnvorhangs während des Anspinnens kommen. Bei der Aufblähung des Spinnvorhangs wiederum können einzelne Formkörper im Spinnvorhang miteinander verkleben, was sich besonders nachteilig auf die Integrität und Homogenität des Formkörperbündels auswirkt. Die Torsion des Spinnvorhangs kann diese Nachteile überwinden, indem insbesondere nicht nur ein kompaktes Formkörperbündel geschaffen wird, sondern die Torsion auch für einen kontinuierlichen, gut steuerbaren Abtransport der Formkörper aus den Spinndüsen sorgen kann, was einem Aufstauen der Formkörper und einem Aufblähen des Spinnvorhangs zuverlässig vorbeugen kann. Ein besonders einfacher und zuverlässiger Verfahrensablauf für das Anspinnen einer Spinnvorrichtung kann somit bereitgestellt werden. Dies führt vorteilhaft auch in weiterer Folge zu einem gleichmäßigeren und stabileren Spinnverfahren.If the shaped bodies are combined by torsion of the spinning curtain about a torsion axis to form the shaped body bundle, the continuous extrusion of the shaped bodies and the bundling into a homogeneous shaped body bundle can be significantly improved, which is particularly beneficial for the reliability of the piecing process. In the torsion of the spinning curtain, the individual shaped bodies are rotated about a common point of contact with each other, so that the compact shaped body bundle is formed at the point of contact. The torsion of the spinning curtain, so the rotation of the individual moldings around the common point of contact, can also be particularly advantageous for a low error rate in the bundling of the moldings act as reliable almost all moldings can be summarized in the bundle. This can also be done with much less effort. In the known from the prior art method for piecing spinning devices, it can also by insufficiently fast removal of the Shaped body after the extrusion of the spinnerets in particular to a damming of the moldings and thus come to a swelling of the spinning curtain during piecing. In the case of the swelling of the spinning curtain, in turn, individual shaped bodies can stick together in the spinning curtain, which has a particularly disadvantageous effect on the integrity and homogeneity of the shaped-body bundle. The torsion of the spinning curtain can overcome these disadvantages, in particular not only a compact shaped body bundle is created, but the torsion can also ensure a continuous, well controllable removal of the moldings from the spinnerets, which reliably prevent damming of the moldings and a swelling of the spinning curtain can. A particularly simple and reliable process for piecing a spinning device can thus be provided. This leads advantageously also subsequently to a more uniform and stable spinning process.
Die Erfindung kann sich zudem besonders auszeichnen, wenn es sich bei dem Spinnverfahren um ein Lyocell-Verfahren handelt, und es sich bei den Formkörpern um cellulosische Formkörper, insbesondere cellulosische Fasern, handelt, welche aus einer Spinnlösung enthaltend Wasser, Zellulose und tertiäres Aminoxid durch Spinndüsen der Spinnvorrichtung extrudiert werden. Bei einem solchen Verfahren kann die Torsion des Spinnvorhangs nämlich bereits im Luftspalt zwischen Spinndüsen und Spinnbad erfolgen, wodurch eine bessere Zugänglichkeit und somit ein deutlich einfacheres Verfahren geschaffen wird.The invention may also be particularly distinguished when the spinning process is a lyocell process, and the shaped bodies are cellulosic shaped bodies, in particular cellulosic fibers, which consist of a spinning solution containing water, cellulose and tertiary amine oxide through spinnerets the spinning device are extruded. In such a method, the torsion of the spinning curtain can in fact already take place in the air gap between spinnerets and spinning bath, whereby a better accessibility and thus a much simpler process is created.
Im Allgemeinen wird festgehalten, dass unter Formkörper sowohl Stapel- und Endlosfasern / Filamente als auch Folien, Schläuche und dreidimensionale Objekte wie z.B. Mikrokugeln, etc. verstanden werden können.In general, it is noted that among shaped bodies, both staple and continuous fibers / filaments as well as films, tubes and three-dimensional objects such as e.g. Microspheres, etc. can be understood.
Die Torsion des Spinnvorhangs zu dem Formkörperbündel kann besonders einfach erfolgen, wenn die Torsionsachse im Wesentlichen parallel zur Extrusionsrichtung der extrudierten Formkörper verläuft. Verläuft die Torsionsachse zudem durch den Mittelpunkt des Spinnvorhangs, so kann sichergestellt werden, dass die Torsion des Spinnvorhangs auf alle Formkörper gleichmäßig und symmetrisch wirkt. Ein besonders homogenes Formkörperbündel ohne innere Spannungen kann damit im Zuge des Anspinnens geschaffen werden, welches die Neigung zu Anspinnfehlern weiter reduzieren kann. Ein besonders zuverlässiges und reproduzierbares Anspinnverfahren kann somit bereitgestellt werden.The torsion of the spinning curtain to the shaped body bundle can be particularly easily done when the torsion axis is substantially parallel to the extrusion direction of the extruded molded body. If the torsion axis also passes through the center of the spinning curtain, it can be ensured that the torsion of the spinning curtain acts uniformly and symmetrically on all shaped bodies. A particularly homogeneous shaped body bundle without internal stresses can thus be created in the course of piecing, which can further reduce the tendency to piecing errors. A particularly reliable and reproducible piecing method can thus be provided.
Werden die Formkörper des Spinnvorhangs mit ihren Enden auf einem rotierbaren Torsionsmittel einer Rotationsvorrichtung abgelegt, welches Torsionsmittel durch seine Rotation die Torsion des Spinnvorhangs bewirkt, so kann eine besonders reproduzierbare und gleichmäßige Torsion des Spinnvorhangs sichergestellt werden. Insbesondere kann die Geschwindigkeit der Torsion des Spinnvorhangs durch die Rotationsgeschwindigkeit des Torsionsmittels an die geforderten Parameter der Spinnvorrichtung angepasst und abgestimmt und somit besonders stabile Spinnverhältnisse während des Anspinnens sichergestellt werden. So können etwa die gewünschte Abzugsgeschwindigkeit der Formkörper von den Spinndüsen und somit die gewünschten Formkörpereigenschaften (wie etwa die Dicke des Formkörperbündels, etc.) durch die Rotationsgeschwindigkeit der Rotationsvorrichtung eingestellt werden, was der Ausbildung von Spinnfehlern zuverlässig vorbeugen kann. Die Reproduzierbarkeit des Anspinnverfahrens kann somit weiter erhöht werden. Zudem kann die Verwendung einer Rotationsvorrichtung zur Torsion des Spinnvorhangs zur körperlichen Entlastung des Bedieners der Spinnvorrichtung beitragen, was die Durchführung des Verfahrens weiter vereinfacht.If the shaped bodies of the spinning curtain are placed with their ends on a rotatable torsional means of a rotary device, which causes torsion means by its rotation, the torsion of the spinning curtain, so a particularly reproducible and uniform twist of the spinning curtain can be ensured. In particular, the speed of torsion of the spinning curtain can be adapted and tuned by the rotational speed of the torsion means to the required parameters of the spinning device, thus ensuring particularly stable spinning conditions during piecing. For example, the desired take-off speed of the shaped bodies from the spinning nozzles and thus the desired molded body properties (such as the thickness of the shaped body bundle, etc.) can be adjusted by the rotational speed of the rotating apparatus, which can reliably prevent the formation of spinning defects. The reproducibility of the piecing process can thus be further increased. In addition, the use of a rotary device to twist the spinning curtain can contribute to the physical relief of the operator of the spinning device, which further simplifies the implementation of the method.
Wird die Rotationsvorrichtung unterhalb des Spinnvorhangs positioniert, so dass die Enden der Formkörper nach deren Extrusion auf dem stillstehenden Torsionsmittel zu liegen kommen, so können die Bediener der Spinnvorrichtung speziell in der initialen Phase des Anspinnens deutlich entlastet werden. Dies insbesondere dann, wenn das Torsionsmittel der Rotationsvorrichtung nach Ablage der Enden der Formkörper schrittweise in ihrer Rotationsgeschwindigkeit bis zum Erreichen einer Endgeschwindigkeit beschleunigt wird. Ebenso ist auch vorstellbar, dass die Rotationsgeschwindigkeit nach Ablage der Formkörper stufenlos beschleunigt wird. Zudem wird festgehalten, dass die Beschleunigung des Torsionsmittels in linearen oder nichtlinearen Beschleunigungsprofilen erfolgen kann, um die Torsion der Formkörper entsprechend deren Eigenschaften zu optimieren. In der initialen Phase ist eine sehr zügige Handhabung des neu extrudierten Spinnvorhangs von großer Bedeutung, da sich Fehler bei der Handhabung in dieser Phase auf die vermehrte Bildung von Spinnfehlern auswirken können, welche ein erneutes Anspinnen nötig machen. Das erfindungsgemäße Verfahren kann sich also durch geringere Neigung zu Anspinnfehlern und durch die feinmotorische und körperliche Entlastung der Bediener, als auch durch hohe Reproduzierbarkeit auszeichnen.If the rotary device is positioned below the spinning curtain, so that the ends of the molded articles come to lie on the stationary torsion means after their extrusion, then the operators of the spinning device can be significantly relieved, especially in the initial phase of piecing. This is especially true when the torsion means of the rotary device is accelerated step by step in its rotational speed until a final speed is reached after the ends of the moldings have been deposited. Likewise, it is also conceivable that the rotational speed is accelerated continuously after storage of the molded body. In addition, it is noted that the acceleration of the torsion can be done in linear or non-linear acceleration profiles to optimize the torsion of the moldings according to their properties. In the initial phase, a very rapid handling of the newly extruded spinning curtain is of great importance, since errors in handling in this phase can affect the increased formation of spinning defects which necessitate re-spinning. The method according to the invention can therefore be characterized by a lower tendency to piecing errors and by the fine motor and physical relief of the operator, as well as by high reproducibility.
Die zuvor genannten Vorteile können verfahrenstechnisch besonders einfach erreicht werden, wenn das Torsionsmittel durch einen rotierbaren Drehteller ausgebildet ist und die Rotationsachse des Drehtellers im Wesentlichen parallel zur Extrusionsrichtung der Formkörper verläuft.The above-mentioned advantages can be achieved in a particularly simple manner in terms of process engineering if the torsion means is formed by a rotatable turntable and the axis of rotation of the turntable runs essentially parallel to the extrusion direction of the shaped bodies.
Die Torsion des Spinnvorhangs kann noch zuverlässiger gestaltet werden, wenn die Enden der Formkörper an Halteelementen des Drehtellers anhaften. Die Halteelemente können nämlich mit der Rotation des Drehtellers die Enden der Formkörper in ihrer Drehbewegung mitnehmen und die Formkörper um einen gemeinsamen Berührungspunkt im Spinnvorhang umeinander verdrehen und somit die Torsion des Spinnvorhangs bewirken.The torsion of the spinning curtain can be made even more reliable if the ends of the moldings adhere to holding elements of the turntable. The holding elements can in fact take with the rotation of the turntable, the ends of the moldings in their rotational movement and rotate the moldings around a common point of contact in the spinning curtain around each other and thus cause the torsion of the spinning curtain.
Wird durch die Torsion des Spinnvorhangs ein Angriffsbereich am Formkörperbündel geschaffen, so kann in dem Anspinnverfahren eine besonders vorteilhafte und einfache Handhabung des Formkörperbündels ermöglicht werden. Durch die Ausbildung eines Angriffsbereichs am Formkörperbündel kann dieses nämlich in nachfolgenden Verfahrensschritten einfach und zuverlässig manipuliert und weiterverarbeitet werden. Zudem wird durch den definierten Angriffsbereich die automatisierte, maschinelle Handhabung und Manipulation des Formkörperbündels ermöglicht. Wird der Angriffsbereich zudem im Bereich des geringsten Durchmessers des tordierten Formkörperbündels geschaffen, so kann eine besonders zuverlässige Handhabung des Formkörperbündels erreicht werden. Durch die Torsion des Spinnvorhangs zu einem Formkörperbündel befindet sich der Bereich des geringsten Durchmessers des Formkörperbündels im Wesentlichen am Scheitelpunkt des Spinnvorhangs, wodurch eine einfache, insbesondere maschinelle Erkennbarkeit des Angriffsbereichs, etwa zur vollautomatischen Manipulation des Formkörperbündels, gegeben ist.If an attack region on the shaped body bundle is created by the torsion of the spinning curtain, a particularly advantageous and simple handling of the shaped body bundle can be made possible in the piecing process. By forming an attack area on the shaped body bundle, this can namely be manipulated and processed further simply and reliably in subsequent method steps. In addition, the automated, mechanical handling and manipulation of the shaped body bundle is made possible by the defined attack area. If the attack area is also created in the region of the smallest diameter of the twisted shaped-body bundle, a particularly reliable handling of the shaped-body bundle can be achieved. Due to the torsion of the spinning curtain into a shaped-body bundle, the area of the smallest diameter of the shaped-body bundle is essentially at the vertex of the spinning curtain, whereby a simple, in particular machine recognizability of the attack area, for example for fully automatic manipulation of the shaped-body bundle, is provided.
Wird zudem ein Angriffsbereich am Formkörperbündel mit einem Durchmesser von 1 bis 20 cm, insbesondere von 3 bis 12 cm, geschaffen, so kann das Anspinnverfahren in seiner Reproduzierbarkeit weiter erhöht werden. Ein solches Formkörperbündel kann sich nämlich durch besonders zuverlässige Handhabungsverhältnisse, insbesondere einer zuverlässigen maschinellen Greifbarkeit, in weiteren Verfahrensschritten auszeichnen.In addition, if an attack area on the shaped body bundle with a diameter of 1 to 20 cm, in particular from 3 to 12 cm, created, so the piecing process can be further increased in its reproducibility. Namely, such a shaped-body bundle can be distinguished by particularly reliable handling conditions, in particular reliable machine tangibility, in further method steps.
Ein besonders einfaches Anspinnverfahren kann geschaffen werden, wenn eine automatische Greifvorrichtung das Formkörperbündel greift und dem Abzugsorgan der Spinnvorrichtung zuführt. Eine automatische Greifvorrichtung kann dabei etwa ein Greifer an einem Manipulatorarm sein, welcher das Formkörperbündel nach der Torsion automatisch greift, über Verlagerung des Manipulatorarms zum Abzugsorgan transportiert und es in dem Abzugsorgan vorsieht (etwa durch Einspannen, Einklemmen, Befestigen, etc.). Die Greifvorrichtung greift dabei das Formkörperbündel vorteilhafterweise an dem ausgebildeten Angriffsbereich und kann somit eine hohe Verfahrenssicherheit gewährleisten. Bei dem Verfahren kann sich zudem besonders vorteilhaft auswirken, wenn das Formkörperbündel erst nach dem Erreichen einer Endgeschwindigkeit der Rotationsvorrichtung im Abzugsorgan vorgesehen wird. Dadurch wird nämlich ermöglicht, dass einerseits das Formkörperbündel vollständig ausgebildet ist und die nötigen Eigenschaften zur Weiterverarbeitung aufweist und andererseits, dass die gewünschten Eigenschaften der extrudierten Formkörper (beispielsweise der gewünschte Fasertiter) erreicht werden. Die Endgeschwindigkeit der Rotationsvorrichtung kann dabei durch die gewünschten Formkörpereigenschaften bzw. durch die benötigte Abzugsgeschwindigkeit der Formkörper aus den Spinndüsen bestimmt werden. Der Manipulatorarm, der das Formkörperbündel im Abzugsorgan vorsieht, sollte dabei vorteilhafterweise sowohl in Bewegungsgeschwindigkeit und Bewegungsprofil auf die Extrusion der Formkörper, insbesondere auf die Abzugsgeschwindigkeit der Formkörper, abgestimmt sein. Zu rasche Bewegungen oder ungünstige Abzugswinkel im Bewegungsverlauf können wiederum zu Anspinnfehlern führen, insbesondere dazu, dass Formkörper im Spinnvorhang reißen, wodurch das Anspinnen erneut durchgeführt werden muss. Durch das erfindungsgemäße Anspinnverfahren können zuvor genannte Anspinnfehler vermieden werden und demgemäß ein Anspinnverfahren mit hoher Reproduzierbarkeit geschaffen werden, welches zudem vollautomatisch ablaufen kann und eine signifikante Erleichterung im Verfahrensablauf für den Bediener der Spinnanlage gegenüber bekannten Verfahren bieten kann.A particularly simple piecing method can be created if an automatic gripping device grips the shaped body bundle and feeds it to the take-off element of the spinning device. An automatic gripping device can be about be a gripper on a manipulator arm, which automatically grips the shaped body bundle after torsion, transported via displacement of the manipulator arm to the trigger and it provides in the trigger member (such as by clamping, clamping, fastening, etc.). The gripping device advantageously engages the shaped body bundle on the trained attack area and can thus ensure a high process reliability. In addition, the method can have a particularly advantageous effect if the shaped-body bundle is provided in the draw-off element only after reaching a terminal speed of the rotary device. This makes it possible, on the one hand, for the shaped-body bundle to be completely formed and to have the necessary properties for further processing and, on the other hand, for the desired properties of the extruded shaped bodies (for example the desired fiber titer) to be achieved. The final speed of the rotary device can be determined by the desired molding properties or by the required take-off speed of the moldings from the spinnerets. The manipulator arm, which provides the shaped body bundle in the take-off member, should advantageously be matched to the extrusion of the shaped bodies, in particular to the withdrawal speed of the shaped bodies, both in terms of movement speed and movement profile. Too rapid movements or unfavorable trigger angles in the course of movement can in turn lead to piecing errors, in particular to the fact that moldings break in the spinning curtain, as a result of which piecing must be carried out again. By means of the piecing process according to the invention, previously mentioned piecing defects can be avoided and accordingly a piecing process with high reproducibility can be provided, which moreover can proceed fully automatically and can offer a significant facilitation in the process sequence for the operator of the spinning plant compared with known processes.
Das Anspinnverfahren kann weiter zuverlässiger gestaltet werden, wenn das Formkörperbündel nach dem Greifen durch die automatische Greifvorrichtung abgeschnitten wird. Vorteilhafterweise wird das Formkörperbündel dabei unterhalb des Angriffsbereichs beschnitten, so dass der untere an der Rotationsvorrichtung abgelegte Teil des Formkörperbündels abgetrennt wird. Das Zuführen des beschnittenen Formkörperbündels an das Abzugsorgan kann somit deutlich erleichtert werden.The piecing process can be further made more reliable if the shaped body bundle is cut off after being gripped by the automatic gripping device. Advantageously, the shaped body bundle is trimmed below the engagement region, so that the lower part of the shaped body bundle deposited on the rotating device is severed. The feeding of the trimmed shaped body bundle to the trigger member can thus be significantly facilitated.
Die Erfindung betrifft zudem eine Anspinnvorrichtung zum Anspinnen einer Spinnvorrichtung, mit einer Bündelungsvorrichtung zur Bündelung von aus den Spinndüsen der Spinnvorrichtung extrudierten Formkörpern, welche Bündelungsvorrichtung eine Rotationsvorrichtung mit zumindest einem um eine Drehachse rotierbaren Mittel aufweist, wobei das rotierbare Mittel derart ausgebildet ist, dass die Formkörper über das Mittel zu dem Formkörperbündel zusammengefasst werden.The invention also relates to a piecing device for piecing a spinning device, comprising a bundling device for bundling molded articles extruded from the spinning nozzles of the spinning device, which bundling device has a rotating device with at least one means rotatable about a rotation axis, wherein the rotatable means is designed such that the shaped articles be summarized via the means to the shaped body bundle.
Die Erfindung hat sich daher weiter die Aufgabe gestellt, eine Anspinnvorrichtung der zuvor erwähnten Art dahingehend zu verbessern, dass das Verfahren zum Anspinnen der Spinnvorrichtung - insbesondere die Bündelung des Spinnvorhangs zu einem Formkörperbündel - unter Verwendung der Anspinnvorrichtung einfach und reproduzierbar und mit geringem Kraftaufwand durchgeführt werden kann.The invention has therefore further set itself the task of improving a piecing device of the type mentioned above in that the method for piecing the spinning device - in particular the bundling of the spinning curtain into a shaped body bundle - be performed using the piecing easily and reproducibly and with little effort can.
Die Erfindung löst die Aufgabe hinsichtlich der Anspinnvorrichtung dadurch, dass das rotierbare Mittel als Torsionmittel, insbesondere als Drehteller, zur Torsion der Formkörper ausgebildet ist und die Drehachse des Torsionsmittels im Wesentlichen parallel zur Extrusionsrichtung der Formkörper ist.The invention solves the problem with regard to the piecing device in that the rotatable means is designed as a torsion means, in particular as a turntable, for torsion of the shaped bodies and the axis of rotation of the torsion means is substantially parallel to the extrusion direction of the shaped bodies.
Weist die Anspinnvorrichtung eine Bündelungsvorrichtung zur Bündelung der extrudierten Formkörper zu einem Formkörperbündel auf, und ist das rotierbare Mittel als Torsionmittel zur Torsion der Formkörper ausgebildet und ist die Drehachse des Torsionsmittels im Wesentlichen parallel zur Extrusionsrichtung der Formkörper, so kann eine besonders standfeste und einfache Anspinnvorrichtung für eine Spinnvorrichtung geschaffen werden, welche besonders ein Verfahren zum Anspinnen der Spinnvorrichtung weiter vereinfachen kann. Die Rotationsvorrichtung mit dem Torsionsmittel kann dabei insbesondere zur Aufnahme von Enden der extrudierten Formkörper aus dem losen Spinnvorhang ausgebildet sein, so dass die Enden der Formkörper auf dem Torsionsmittel abgelegt werden können und über die Drehbewegung des Torsionsmittels eine Torsion des Spinnvorhangs erzeugt wird. Die Drehbewegung des Torsionsmittels und damit verbundene Torsion des Spinnvorhangs zu einem Formkörperbündel kann somit den schwierigen Schritt der Bündelung der Formkörper durch eine konstruktiv besonders einfache Vorrichtung ersetzen.If the piecing device has a bundling device for bundling the extruded shaped bodies to form a shaped body bundle, and if the rotatable means is designed as a torsion means for torsion of the shaped bodies and if the axis of rotation of the torsion means is substantially parallel to the extrusion direction of the shaped bodies, a particularly stable and simple piecing apparatus can be used a spinning device can be provided, which can further simplify a method for piecing the spinning device on. The rotation device with the torsion means may be formed in particular for receiving ends of the extruded molded bodies from the loose spinning curtain, so that the ends of the shaped bodies can be deposited on the torsion means and a torsion of the spinning curtain is generated via the rotational movement of the torsion. The rotational movement of the torsion means and associated torsion of the spinning curtain to a shaped body bundle can thus replace the difficult step of bundling the shaped body by a structurally particularly simple device.
Ist das Torsionsmittel als Drehteller ausgebildet, so kann die Torsion der extrudierten Formkörper auf konstruktiv besonders einfache Weise erfolgen. Dies insbesondere dann, wenn der Drehteller im Wesentlichen parallel zur Extrusionsrichtung der aus den Spinndüsen extrudierten Formkörper rotierbar ausgebildet ist. Dabei kann nämlich eine Rotationsvorrichtung zur Torsion des aus extrudierten Formkörpern bestehenden losen Spinnvorhangs um eine Torsionsachse parallel zur Extrusionsrichtung der Formkörper geschaffen werden, welche besonders standfest und zuverlässig ein kompaktes Formkörperbündel erzeugen kann. Die Zuverlässigkeit und Standfestigkeit der Spinnvorrichtung kann somit insgesamt weiter erhöht werden. Dies insbesondere dann, wenn das Torsionsmittel zur Torsion der extrudierten Formkörper um eine gemeinsame Torsionsachse ausgebildet ist und die Torsionsachse der Formkörper mit der Rotationsachse des Torsionsmittels zusammenfällt.If the torsion means is designed as a turntable, the torsion of the extruded shaped bodies can take place in a structurally particularly simple manner. This is especially true when the turntable is substantially parallel to the Extrusion direction of the extruded from the spinnerets molded body is rotatable. Namely, a rotary device for torsion of the existing loose extruded moldings loose spinning curtain can be created about a torsion axis parallel to the extrusion direction of the moldings, which can produce particularly stable and reliable a compact moldings bundle. The reliability and stability of the spinning device can thus be further increased overall. This is especially true if the torsion means for torsion of the extruded shaped bodies is formed around a common torsion axis and the torsion axis of the shaped bodies coincides with the axis of rotation of the torsion means.
Im Allgemeinen wird zudem erwähnt, dass sich die erfindungsgemäße Anspinnvorrichtung besonders bevorzugt zum Anspinnen einer Spinnvorrichtung zur Extrusion cellulosischer Formkörper aus einer Spinnlösung enthaltend Wasser, Zellulose und tertiäres Aminoxid eignen kann.In general, it is also mentioned that the spinning device according to the invention may be particularly suitable for spinning a spinning device for the extrusion of cellulosic moldings from a spinning solution containing water, cellulose and tertiary amine oxide.
Die Anspinnvorrichtung kann in ihrer Zuverlässigkeit weiter erhöht werden, wenn das Torsionsmittel Halteelemente zur Erhöhung der Haftung zwischen Formkörpern und Torsionsmittel aufweist. Dies insbesondere wenn die Halteelemente als Haken ausgebildet sind.The piecing device can be further increased in its reliability if the torsion means holding elements to increase the adhesion between moldings and torsion means. This in particular if the holding elements are designed as hooks.
Weist die Anspinnvorrichtung zudem zumindest einen Manipulatorarm und jeweils zumindest einen Endeffektor am Manipulatorarm auf, wobei zumindest ein Endeffektor die Bündelungsvorrichtung ausbildet, so kann eine standfeste Spinnvorrichtung geschaffen werden, welche ein einfaches und reproduzierbares Anspinnen ermöglicht. Die Anspinnvorrichtung kann dabei insbesondere das Anspinnen der Spinnvorrichtung vollautomatisch durchführen, um die Bediener der Spinnvorrichtung körperlich und motorisch zu entlasten. Während in den eingangs erwähnten, bekannten Spinnvorrichtungen ein großer Kraftaufwand notwendig ist, um beim Anspinnen das aus den Spinndüsen extrudierte Formkörperbündel in einem Abzugsorgan der Spinnvorrichtung vorzusehen, so können die Bediener durch den vergleichsweise geringen benötigten Kraftaufwand in der erfindungsgemäßen Spinnvorrichtung stark entlastet werden. Zudem kann sich die erfindungsgemäße Spinnvorrichtung durch eine besonders einfache Handhabung und hohe Sicherheit in der Bedienung auszeichnen.If the piecing device additionally has at least one manipulator arm and at least one end effector on the manipulator arm, wherein at least one end effector forms the bundling device, then a sturdy spinning device can be created, which enables simple and reproducible piecing. The piecing device can in particular perform the piecing of the spinning device fully automatically to relieve the operator of the spinning device physically and motorically. While in the aforementioned, known spinning devices, a large amount of force is necessary to provide the spinning of the spinneret extruded molding bundles in a trigger member of the spinning device when piecing, the operator can be greatly relieved by the relatively small amount of force required in the spinning device according to the invention. In addition, the spinning device according to the invention can be characterized by a particularly simple handling and high security in the operation.
Die Handhabung der Spinnvorrichtung kann weiter vereinfacht werden, wenn die Anspinnvorrichtung einen ersten Manipulatorarm mit einem ersten Endeffektor aufweist, wobei der erste Endeffektor einen Greifer zum Greifen eines Formkörperbündels aufweist. Der Greifer am ersten Manipulatorarm kann dabei derart ausgebildet sein, dass dieser das Formkörperbündel zuverlässig erfassen und einem Abzugsorgan der Spinnvorrichtung zuführen kann. Der Transport des Formkörperbündels von den Spinndüsen zum Abzugsorgan kann durch Verlagerung des ersten Manipulatorarms, insbesondere entlang frei wählbaren Trajektorien im Raum erfolgen. Es kann dabei in einem Verfahren zum Anspinnen der Spinnvorrichtung auf die vergleichsweise körperlich anstrengenden und schwer reproduzierbaren Schritte des manuellen Einfädelns des Formkörperbündels verzichtet werden. Dies stellt nicht nur eine besondere körperliche Entlastung für die Bediener der Spinnvorrichtung dar, sondern kann auch in hohem Maße zur Erhöhung der Sicherheit gegenüber Bedienfehlern der Spinnvorrichtung beitragen.The handling of the spinning device can be further simplified if the piecing device has a first manipulator arm with a first end effector wherein the first end effector has a gripper for gripping a shaped body bundle. The gripper on the first manipulator arm can be designed in such a way that it can reliably grasp the shaped body bundle and supply it to a take-off element of the spinning device. The transport of the shaped body bundle from the spinnerets to the take-off member can take place by displacing the first manipulator arm, in particular along freely selectable trajectories in space. It can be dispensed with in a method for piecing the spinning device to the relatively physically demanding and difficult to reproduce steps of manual threading of the molding bundle. This not only represents a special physical relief for the operators of the spinning device, but also can greatly contribute to increasing the safety against operating errors of the spinning device.
Weist zudem die Anspinnvorrichtung einen zweiten Manipulatorarm mit einem zweiten Endeffektor auf, wobei der zweite Endeffektor die Bündelungsvorrichtung aufweist, so kann eine besonders flexible Anspinnvorrichtung mit einer Bündelungsvorrichtung geschaffen werden, welche Bündelungsvorrichtung somit bei Bedarf zwischen einer Gebrauchsstellung und einer Ruhestellung verlagerbar ausgebildet ist. Die Anspinnvorrichtung kann demnach auf die Anforderungen des Verfahrens flexibel reagieren: beispielsweise kann die Bündelungsvorrichtung bei Nichtgebrauch in eine Ruhestellung verlagert werden und somit unerwünschte Behinderungen durch die Bündelungsvorrichtung in der Spinnvorrichtung vermieden werden. Die Rotationsvorrichtung ist damit je nach Verfahrensstand zwischen Spinndüsen und Spinnbadbehälter ein- und ausfahrbar. Eine zuverlässigere Spinnvorrichtung kann hiermit geschaffen werden. Eine konstruktiv einfache Bündelungsvorrichtung kann zudem geschaffen werden, wenn diese durch die Rotationsvorrichtung ausgebildet wird.In addition, if the piecing device has a second manipulator arm with a second end effector, wherein the second end effector has the bundling device, a particularly flexible piecing device with a bundling device can be provided, which bundling device is thus displaceable between a use position and a rest position if required. The piecing device can therefore respond flexibly to the requirements of the method: for example, the bundling device can be displaced when not in use in a rest position and thus undesirable obstructions are avoided by the bundling device in the spinning device. Depending on the state of the process, the rotary device can thus be moved in and out between spinnerets and spin bath containers. A more reliable spinning device can be provided herewith. A structurally simple bundling device can also be created when it is formed by the rotary device.
Die Handhabung des Formkörperbündels durch die Anspinnvorrichtung kann weiter verbessert werden, wenn die Anspinnvorrichtung zudem eine Schneidevorrichtung zum Abschneiden des Formkörperbündels aufweist. Besonders bevorzugt kann die Schneidevorrichtung am ersten Manipulatorarm vorgesehen sein und insbesondere mit dem Greifer derart wirkverbunden sein, dass das Abschneiden des Formkörperbündels nach einem erfolgreichen Greifvorgang des Greifers automatisch erfolgt.The handling of the shaped body bundle by the piecing apparatus can be further improved if the piecing apparatus also has a cutting device for cutting off the shaped body bundle. Particularly preferably, the cutting device can be provided on the first manipulator arm and in particular be operatively connected to the gripper in such a way that the cutting of the shaped body bundle takes place automatically after a successful gripping operation of the gripper.
Die Erfindung hat sich weiter die Aufgabe gestellt, eine Spinnvorrichtung der eingangs erwähnten Art zuverlässiger zu gestalten und das Anspinnen der Spinnvorrichtung zu erleichtern.The invention has also set itself the task of making a spinning device of the type mentioned more reliable and to facilitate the piecing of the spinning device.
