Definitions
- the present invention relates to a method for operating a spindle of a double wire twisting or cabling machine according to the preamble of claim 1 and a double wire twisting or cabling machine according to the preamble of claim 8.
- the spindle of a double-wire twisting or cabling machine is used to produce twists, wrapping threads or the like from at least two threads drawn from bobbins, which are generally referred to as inner thread or outer thread.
- the bobbin for the inner thread is often positioned in a so-called bobbin pot, which is supported on a thread deflection device in the region of the axis of rotation of the spindle and is secured against rotation by magnets.
- the bobbin of the associated outer thread preferably hangs in a creel which is arranged above or behind the double-wire twisting or cabling machine.
- the outer thread starting from the outer thread brake, is inserted centrally into a cord spindle and exits radially on a rotating storage disk which is attached to the cord spindle below a twisting plate.
- the outer thread wraps around the storage disk, which compensates for thread tensions arising from thread supply fluctuations, at least partially, before the thread is transferred over the outer edge of the twisting plate into a free thread balloon, the shape and diameter of which depend on various factors. Some of these factors are, for example, the diameter of the storage disc and the twist plate, the balloon height, the titer of the thread and the spindle speed of the job.
- a cabling device in which a balloon limiting pot prevents the formation of a free thread balloon. This means that the outer thread rotating around the spindle is limited in its radial extent by a rotating pot. Furthermore, due to the friction of the running outer thread on the inner wall of the balloon limiting pot, the thread tension is regulated, which corresponds to the effect of using a storage disk.
- the thread tension of the outer thread is lower than that of the DE 41 21 913 A1 known cabling device with a storage disk, which by the EP 1 167 597 B1 known cabling device
- the rotating balloon limiting pot is exposed to a not insignificant wear from the running outer thread and the balloon limiting pot must also be constantly moved as a rotating mass by the spindle drive.
- the air friction of the rotating balloon limiting pot creates additional losses that have to be compensated for by the spindle drive.
- a method for operating a spindle of a double-wire twisting or cabling machine, which is characterized by a reduced energy consumption, and an associated double-wire twisting or cabling machine are in the DE 10 2008 033 849 A1 described.
- thread-turning devices In connection with the spindles of double-wire twisting or cabling machines, thread-turning devices are also known which are designed, for example, in the manner of a wing.
- the object of the invention is to develop a method for operating a spindle of a double-wire twisting or cabling machine which, on the one hand, is characterized by a reduced energy consumption and, on the other hand, ensures safe, correct operation of the spindles at all times.
- This object is achieved according to the invention by a method for operating a spindle at a work station of a double-wire twisting or cabling machine, in which an outer thread is drawn off from a supply spool and orbits the spindle in a thread balloon.
- the work station of the double-wire twisting or cabling machine has a bobbin, a rotatably mounted thread deflecting device, a device for forming a twisting or cabling point, a device for influencing the balloon thread tension via which the thread balloon shape can be adjusted, and a control loop.
- the work station is operated without a storage disk and the thread balloon is driven via a fixed ejection point on a rotatable thread deflection device, the control loop regulating the device for influencing the balloon thread tension in such a way that there is always a minimum thread balloon size, with a fixed predetermined one Throwing geometry of the outer thread results from the fixed dropping point of the thread deflecting device, and due to the fixed dropping point of the thread deflecting device and the increased thread tension in the area of the fixed dropping point, a dropping angle of the outer thread is automatically set, which leads to a minimization of the diameter of the free thread balloon being formed.
- the associated double wire twisting or cabling machine has the features described in claim 4.
- the method according to the invention not only has the advantage that the spindle has a good energy balance during the twisting or cabling process due to the thread balloon being minimized in diameter, but the omission of any storage of the outer thread during the entire operating time also leads to a very gentle treatment of the Thread material. This means that not using a storage disk generates various other, not inconsiderable advantages in addition to the saving of components, which can be quite expensive.
- the lower surface variance resulting from the omission of a storage disk leads, for example, to improved concentricity properties of the spindle and thus to an improved vibration behavior of this component.
- the method according to the invention not only avoids that yarn damage due to greater surface contact of the thread material with a storage disc or with a balloon limiting pot, but also due to the shape and size of the diameter of the thread balloons surrounding the spindle, the prevailing one is also easy Thread tension recognizable, which can be easily corrected if necessary.
- the control loop regulates the device for influencing the balloon thread tension in such a way that a minimum thread balloon size is automatically obtained.
- This device for influencing the balloon thread tension keeps the feeding speed of the thread as constant as possible, or, through continuous adaptation, fluctuations in the delivery of the thread, which lead to breakage of the thread or to fluctuations in the shape and size of the rotating thread balloon avoided.
- the rotatably mounted thread deflection device is designed as a wrap-around brake, in which only a relatively small thread storage volume is used.
- the device for influencing the balloon thread tension is preferably connected to a control circuit which regulates the device in such a way that a desired thread balloon size can be set.
- control loop also regulates the device for influencing the balloon thread tension when the spindle is raised or lowered and in the event of a short-term voltage voltage interruption in such a way that a thread balloon size results in which both a contact with the fixed spindle cup and a contact between the two Separators arranged at work stations is avoided.
- Such a design enables a compact construction of the work stations with a reduced division of work stations compared to known double wire twisting or cabling machines, with the result that the space required for installing the double wire twisting or cabling machines according to the invention is reduced.
- the double-wire twisting or cabling machine has a large number of workstations, each of which has a spindle, a bobbin pot, a thread deflection device mounted in rotation, a device for forming a twisting or cabling point, and a device for influencing the balloon thread tension via which the thread balloon shape is adjustable and has a control loop.
- the work station is designed without a storage disc and the rotatably mounted thread deflection device has a fixed ejection point for the outer thread, the control loop being set up in such a way that the device for influencing the balloon thread tension can be regulated in such a way that there is always a minimal thread balloon size, which results in results in a fixed discharge geometry of the outer thread from the fixed discharge point of the thread deflection device, and due to the fixed discharge point of the thread deflection device and the increased thread tension in the area of the fixed discharge point, a discharge angle of the outer thread automatically arises, which minimizes the diameter of the free thread balloon being formed leads.
- Such a design not only has the advantage that fewer components per spindle are required because there is no storage disc or a rotating balloon limiting pot, but due to the fixed ejection point on the rotatably mounted thread deflection device, proper rotation of the thread balloon is also ensured at all times.
- the fixed discharge point on the rotatably mounted thread deflection device can have different embodiments.
- the fixed drop point can be formed, for example, by an eyelet which is arranged in the outer region of a twisting plate or in the free end region of a twisting wing.
- the fixed discharge point is formed by the exit of a closed channel, which preferably extends between a thread outlet bore in the region of the axis of rotation of the spindle and the outer region of a twist plate, or between a thread outlet bore in the region of the axis of rotation of the spindle and the end region of a twist wing .
- the fixed discharge point is formed by the end of a slot which is open at the bottom and which, for example, is between a thread outlet bore in the region of the axis of rotation of the spindle and the outer region of a twist plate or between a thread outlet bore in the region of the axis of rotation of the spindle and the end region of a twine wing is arranged.
- the fixed discharge point is part of a rotatably mounted belt brake.
- Such a wrap-around brake preferably has a hub-like base body with a thread guide bore running axially with respect to the axis of rotation of the spindle and a thread outlet bore extending radially therefrom.
- the wrap-around brake has a plate-shaped attachment connected to the base body, which is equipped with a fixed ejection point for the thread, preferably with an abrasion-resistant eyelet.
- the twisting plates, the twisting wings and / or the wrapping brake are preferably designed in such a way that they are self-threading. That is, when you restart the thread is automatically threaded into the drop point of the thread deflecting device.
- the controllable device for influencing the balloon thread tension is preferably designed either as a brake or as an active delivery mechanism. This means that the thread deflection device is preceded by a controllable device for influencing the thread tension, by means of which the feed speed of the thread is adjusted so that the thread tension of the thread entering the thread deflection device always has a value which is a function of the diameter of the thread balloon orbiting the spindle minimizes the geometry of the spindle, which has a positive influence on the energy consumption of the spindle drive.
- a work station of a double-wire twisting or cabling machine is generally identified with the reference number 1.
- the method according to the invention is also explained below on the basis of the illustrated work station 1.
- the work station 1 of the double-wire twisting or cabling machine has, as usual, a gate 4 which is generally positioned above or behind the work station 1 and which serves to receive at least one first supply spool 7, from which a so-called outer thread 5 is drawn off.
- the work station 1 also has a spindle 2, which in the present exemplary embodiment is designed as a so-called cabling spindle.
- the spindle 2 has a bobbin 19 in which a second supply bobbin 15 is mounted, from which a so-called inner thread 16 is drawn off overhead, which is fed to a balloon eyelet arranged above the spindle 2 or a so-called compensation system 9.
- the bobbin 19 is mounted on the rotatable thread deflection device 20, which in the embodiment of the Fig. 1 is designed as a twist plate 8.
- the bobbin 19 supported on the rotatable thread deflection device 20 is secured against rotation, preferably by a magnetic device (not shown).
- the thread deflection device 20 of the spindle 2 is acted upon by a spindle drive 3, which, as in the exemplary embodiment, can be either a direct drive or an indirect drive. In the latter case, the thread deflection device 20 is connected to a corresponding drive, for example via a belt drive.
- the outer thread 5 drawn off from the first supply spool 7 is fed to a controllable device 6 arranged in the thread run between the creel 4 and the spindle 2 for influencing the thread tension.
- the device 6 is connected via control lines 27 to a control circuit 18 which controls the thread tension applied by the device 6 to the outer thread 5.
- the device 6 for influencing the thread tension in the thread running direction is arranged in front of the thread deflection device 20, which in the exemplary embodiment is designed as a twist plate 8.
- the outer thread 5 passes through the spindle drive 3 in the region of the axis of rotation 28 of the spindle drive after the device 6 and emerges from the hollow axis of rotation 28 of the spindle drive 3 in the radial direction below the twist plate 8 through a so-called thread outlet bore 29.
- the outer thread 5 then runs to the outer region 30 of the twisting plate 8, where a fixed drop point 21 for the outer thread 5 is installed.
- This fixed drop point 21 can, as in the embodiment of FIG Fig. 1 shown, are formed as an eyelet 23.
- the outer thread 5 is deflected upward in the area of the eyelet 23 of the twisting plate 8 and circles around the bobbin 19 of the spindle 2, in which a second supply bobbin 15 is positioned, forming a free thread balloon B.
- the outer thread 5 drawn off from the first supply bobbin 7 and the inner thread 16 drawn off from the second supply bobbin 15 are brought together in the region of the balloon eyelet or the compensation system 9.
- the position of the balloon eyelet or the compensation system 9 determines the height of the free thread balloon B that is formed.
- there is the so-called cabling or cording point in which the two threads, the outer thread 5 and the inner thread 16, converge and form a cord thread 17, for example.
- a thread draw-off device 10 is arranged above the cabling point, by means of which the cord thread 17 is drawn off and fed to a winding and winding device 12 via a compensating element, such as a dancer device 11.
- the winding and winding device 12 has, as usual, a drive roller 13 and a spool 14 driven by the drive roller 13 with a friction fit.
- the device 6 for influencing the thread tension has the special task of varying, in particular increasing, the thread tension of the outer thread 5 in front of the thread deflecting device 20 equipped with a fixed ejection point 21, both on a storage disk and on a co-rotating one Balloon limiting pot, the use of which to compensate for irregularities in the thread feed has so far been dispensed with.
- the controllable thread tension applied by the device 6 to the outer thread 5 preferably has an order of magnitude which, depending on the geometry of the spindle 2, leads to a minimization of the free thread balloon B. This is achieved by a predetermined discharge geometry of the outer thread 5, which results from the fixed discharge point 21 of the thread deflection device 20.
- the device 6 for influencing the thread tension can either be designed as an electronically controlled brake or as an active delivery mechanism. A combination of the two aforementioned components can also be used. As a configuration variant of the delivery plant, for example, a godet, a serrated lock washer or a drive roller with a corresponding pressure roller are possible. It is important that in order to maintain the free thread balloon B with a constant, minimized diameter, the device 6 always has an active, controllable influence on the thread tension. That is, the control circuit 18 connected to the device 6 via control lines 27 uses, for example, the tension of the outer thread 5 before or after the formation of the free thread balloon B as the manipulated variable.
- the diameter of the thread balloon B or the power consumption of the spindle drive 3 can alternatively or additionally be used as a manipulated variable.
- the thread tension for regulating the device 6 can be monitored electronically and / or mechanically, for example by means of a dancer roll or a conical roller.
- a dancer roll which is connected to the outer thread 5
- its deflection is detected on the basis of the changing thread tension, which is used as a manipulated variable for the device 6 for influencing the thread tension.
- FIGS. 2a, 2b and 2c show various embodiments of a thread deflection device 20 designed as a twist plate 8a, 8b, 8c, each equipped with a fixed ejection point 21.
- the twist plate 8a shown has, for example in the region of the axis of rotation 28 of the spindle 2, an axially extending thread guide bore 31 and a thread outlet bore 29 branching radially therefrom. Furthermore, the twisting plate 8a is spaced apart from a radially arranged thread outlet bore 29 and somewhat spaced apart from its outer region 30 via an eyelet 23, which is preferably made of wear-resistant material, for example ceramic, and which functions as a fixed ejection point 21 for the thread deflection device 20.
- the outer thread 5 originating from the first supply bobbin 7 runs through the axis of rotation 28 of the spindle 2 into the thread guide bore 31 of the twist plate 8a and then via the thread outlet bore 29 to the wear-resistant eyelet 23 which rotates with the twist plate 8a .
- the outer thread 5 crossing the eyelet 23 is likewise subjected to a rotation and thereby forms a thread balloon B which is minimized in terms of its diameter.
- the twist plate 8b shown also has an axially extending thread guide bore 31 in the region of the axis of rotation 28 of the spindle 2 and a thread outlet bore 29 branching radially therefrom.
- the thread outlet bore 29 is adjoined by a preferably linear thread guide device which leads to the outer region 30 of the twisting plate 8b and which either, as in FIG Fig.2b shown as a closed channel 25 or, as in Fig. 2c shown as a downwardly open slot 24 is formed.
- the outlet point of the channel 25 or the slot 24 each form a fixed discharge point 21 for the thread deflecting device 20 and are designed to be wear-resistant, for example by a ceramic lining.
- twisting plate 8a, 8b, 8c both form the eyelet 23 and the closed channel 25 or the downwardly open slot 24 each form a fixed release point 21 for the thread deflecting device 20.
- FIGS. 3a, 3b and 3c show various embodiments of a thread deflecting device 20 designed as a twisted wing 22 and equipped with a fixed ejection point 21.
- the thread wing 22a shown has, for example, a base body 33 designed in the manner of a hub, to which a wing-like extension 34 is formed, which in its end region 35 is equipped with an eyelet 23, which is preferably made of wear-resistant material, for example ceramic.
- the eyelet 23 also functions as a fixed ejection point 21 for the thread deflecting device 20.
- the twisted wing 22a also has an axially extending thread guide bore 31 in the region of the axis of rotation 28 of the spindle 2 or its base body 33 and a thread outlet bore 29 branching radially therefrom.
- the base body 33 of the twisted wing 22a or the wing-like extension 34 is also equipped with a counterweight 36, which balances the centrifugal forces generated by the wing-like extension 34 during operation of the twisted wing 22a.
- the outer thread 5 originating from the first supply spool 7 runs through an axial thread guide bore 31 arranged in the region of the axis of rotation 28 of the spindle 2 in the twist wing 22a and through one of the latter axial thread guide bore 31 radially branching thread outlet bore 29 to a wear-resistant eyelet 23 arranged in the end region 35 of the wing 34.
- the outer thread 5 passing through the eyelet 23 is also rotated by the circumferential thread wing 22a and thereby forms a thread balloon B, the diameter of which is minimized.
- the in Fig.3b The twisted wing 22b shown in the region of the axis of rotation 28 of the spindle 2 likewise has an axially running thread guide bore 31 and a thread outlet bore 29 branching radially therefrom, to which a linear thread guide device leading to the end region 35 of the wing 34 is connected.
- the linear thread guide device is either, as in Fig.3b shown with the twine wing 22b, as a closed channel 25 or, as in Fig. 3c shown with the twine wing 22c, formed as a downwardly open slot 24.
- the outlet point of the channel 25 or the slot 24 each form a fixed discharge point 21 for the thread deflecting device 20 designed as a twisted wing 22b or 22c.
- the Fig. 4 shows, as an alternative embodiment, a thread deflection device 20 designed as a looping brake 26.
- a thread deflection device 20 designed as a looping brake 26.
- Such a construction has a hub-like base body 37 to which a plate-like extension 38 is connected.
- the looping brake 26 also has in the area of the axis of rotation 28 of the spindle 2 an axially running thread guide bore 31, from which a thread outlet bore 29 branches off radially, which ends in the area of the lateral surface 39 of the base body 37.
- the plate-like extension 38 of the wrap-around brake 26 is equipped with an eyelet 23, which is preferably made of wear-resistant material, for example ceramic, and which functions as a fixed drop point 21 for the thread deflection device 20. That is, during the operation of the spindle 2, the outer thread 5 originating from the first supply bobbin 7 runs via the thread guide bore 31 into the base body 37 of the looping brake 26 and via the radially arranged thread outlet bore 29 onto the outer surface 39 of the hub-like base body 37.
- the outer thread 5 leaves the base body 37 after a wrap of, for example, approximately 120 ° in the direction of the wear-resistant eyelet 23, which is arranged in the region of the plate-like extension 38 of the wrap-around brake 26 and which rotates with the wrap-around brake 26.
- the outer thread 5, which receives an additional thread tension due to its partial wrap around the hub-like base body 37 of the wrap brake 26, is also rotated by the circumferential eyelet 23 and forms a thread balloon B which is minimized in terms of its diameter.

Die Spindel einer Doppeldrahtzwirn- oder Kabliermaschine dient bekanntlich zur Herstellung von Zwirnen, Umwindefäden oder Ähnlichem aus mindestens zwei von Spulen abgezogenen Fäden, die in der Regel als Innenfaden oder als Außenfaden bezeichnet werden.
Die Spule für den Innenfaden ist dabei oft in einem so genannten Spulentopf positioniert, der im Bereich der Drehachse der Spindel auf einer Fadenumlenkeinrichtung abgestützt und durch Magnete gegen Rotation gesichert ist.

Bei der Doppeldrahtzwirn- oder Kabliermaschine gemäß
Der Außenfaden umschlingt dabei die Speicherscheibe, die durch Fadenlieferschwankungen entstehende Fadenspannungen ausgleicht, zumindest teilweise, bevor der Faden über den äußeren Rand des Zwirntellers in einen freien Fadenballon überführt wird, dessen Form und Durchmesser von verschiedenen Faktoren abhängig ist. Einige dieser Faktoren sind zum Beispiel der Durchmesser der Speicherscheibe und des Zwirntellers, die Ballonhöhe, der Titer des Fadens sowie die Spindeldrehzahl der Arbeitsstelle.The outer thread wraps around the storage disk, which compensates for thread tensions arising from thread supply fluctuations, at least partially, before the thread is transferred over the outer edge of the twisting plate into a free thread balloon, the shape and diameter of which depend on various factors. Some of these factors are, for example, the diameter of the storage disc and the twist plate, the balloon height, the titer of the thread and the spindle speed of the job.
Da eine optimale Abstimmung der vorgenannten Faktoren aufeinander einen relativ großen Aufwand erfordert, bzw. nur begrenzt möglich ist, wird dieser Aufwand oftmals gescheut, mit der Folge, dass die Form und der Durchmesser des freien Fadenballons nicht optimal sind, was sich unter anderem sehr nachteilig auf die Energieaufnahme der Spindel auswirkt.Since optimal coordination of the aforementioned factors requires a relatively large amount of effort, or is only possible to a limited extent, this effort is often spared, with the result that the shape and the diameter of the free thread balloon are not optimal, which is very disadvantageous, among other things affects the energy consumption of the spindle.
Es ist deshalb bereits vorgeschlagen worden, bei der Regelung der Form- und Durchmesserschwankungen des freien Fadenballons, die bekanntlich durch Fadenliefergeschwindigkeitsschwankungen entstehen, auf den Einsatz einer unterhalb eines Zwirntellers angeordneten Speicherscheibe zu verzichten und die Fadenspannung stattdessen mittels eines mit der Spindel mitrotierenden Ballonbegrenzungstopfes zu regeln.It has therefore already been proposed to dispense with the use of a storage disk arranged below a twist plate when regulating the shape and diameter fluctuations of the free thread balloon, which are known to be caused by thread delivery speed fluctuations, and instead to regulate the thread tension by means of a balloon limiting pot rotating with the spindle.
Durch die
Durch den Einsatz des als Ballonbegrenzer ausgebildeten mitrotierenden Topfes, der die radialen Kräfte des Außenfadens aufnimmt, ist zwar die Fadenspannung des Außenfadens geringer als bei der aus der
In der Praxis ist mit Kabliereinrichtungen, die über einen mitrotierenden Ballonbegrenzungstopf verfügen, gegenüber Kabliervorrichtungen, die mit einer Speicherscheibe und einem freien Fadenballon arbeiten, keine Energieeinsparung erzielbar.In practice, no energy savings can be achieved with cabling devices that have a rotating balloon limiting pot compared to cabling devices that work with a storage disk and a free thread balloon.
Ein Verfahren zum Betreiben einer Spindel einer Doppeldrahtzwirn- oder Kabliermaschine, welches sich durch eine reduzierte Energieaufnahme auszeichnet, sowie eine zugehörige Doppeldrahtzwirn- oder Kabliermaschine sind in der
Bei diesem bekannten Verfahren wird vorgeschlagen, die Zufuhrgeschwindigkeit des Außenfadens so einzustellen, dass sich im Bereich des Zwirntellers keine Speicherung einstellen kann und die Fadenspannung des Außenfadens einen Wert annimmt, der den Durchmesser des die Spindel umkreisenden freien Fadenballons in Abhängigkeit von der Geometrie der Spindel minimiert. Das heißt, bei diesem bekannten Verfahren wird die Fadenspannung derart eingestellt, dass die eingestellte Fadenspannung größer ist, als die sich selbst einstellende Fadenspannung bei der Verwendung einer Speicherscheibe beziehungsweise eines mitrotierenden Topfes.In this known method it is proposed to set the feed speed of the outer thread such that no storage can occur in the area of the twist plate and the thread tension of the outer thread assumes a value that minimizes the diameter of the free thread balloon encircling the spindle depending on the geometry of the spindle . This means that in this known method the thread tension is set such that the thread tension set is greater than the self-adjusting thread tension when using a storage disk or a rotating pot.
Durch das in der
Bei der
Da die erforderliche Antriebsleistung einer Spindel, wie vorstehend bereits erläutert, unter anderem stark vom Ballondurchmesser abhängig ist, führt die Reduzierung des Durchmessers des freien Fadenballons dazu, dass die zur Ausbildung und Aufrechterhaltung der Rotation des Fadenballons aufzubringende Energie sinkt.Since the required drive power of a spindle, as already explained above, is heavily dependent, among other things, on the balloon diameter, the reduction in the diameter of the free thread balloon leads to a decrease in the energy which is required to form and maintain the rotation of the thread balloon.
Bei dem durch die
Im Zusammenhang mit den Spindeln von Doppeldrahtzwirn- oder Kabliermaschinen sind des Weiteren auch Fadendreheinrichtungen bekannt, die zum Beispiel nach Art eines Flügels ausgebildet sind.In connection with the spindles of double-wire twisting or cabling machines, thread-turning devices are also known which are designed, for example, in the manner of a wing.
In der
Da die Spindeln dieser bekannten Doppeldrahtzwirn- oder Kabliermaschinen aber weder mit einer Speicherscheibe noch mit einem mitrotierenden Topf ausgestattet sind und auch keine regelbare Einrichtung aufweisen, mit der die Fadenspannung des Außenfadens auf einen Wert gebracht wird, bei dem der Durchmesser des die Spindel umkreisenden freien Fadenballons in Abhängigkeit von der Geometrie der Spindel minimiert ist, stellen sich bei den Spindeln dieser bekannten Doppeldrahtzwirn- oder Kabliermaschinen freie Fadenballons ein, deren Form und Durchmesser keinesfalls optimal sind.However, since the spindles of these known double-wire twisting or cabling machines are neither equipped with a storage disk nor with a rotating pot and also have no controllable device with which the thread tension of the outer thread is brought to a value in which the diameter of the free thread balloons encircling the spindle depending on the geometry of the spindle is minimized, free spool balloons arise in the spindles of these known double-wire twisting or cabling machines, the shape and diameter of which are in no way optimal.
Mit flügelartig ausgebildeten Dreheinrichtungen, wie sie in der
Ausgehend vom vorstehend genannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zum Betreiben einer Spindel einer Doppeldrahtzwirn- oder Kabliermaschine zu entwickeln, welches sich einerseits durch eine reduzierte Energieaufnahme auszeichnet und anderseits jederzeit einen sicheren, ordnungsgemäßen Betrieb der Spindeln gewährleistet.Starting from the above-mentioned prior art, the object of the invention is to develop a method for operating a spindle of a double-wire twisting or cabling machine which, on the one hand, is characterized by a reduced energy consumption and, on the other hand, ensures safe, correct operation of the spindles at all times.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren zum Betreiben einer Spindel an einer Arbeitsstelle einer Doppeldrahtzwirn- oder Kabliermaschine gelöst, bei welchem ein Außenfaden von einer Vorlagespule abgezogen wird und die Spindel in einem Fadenballon umkreist. Die Arbeitsstelle der Doppeldrahtzwirn- oder Kabliermaschine weist dabei einen Spulentopf, eine rotierbar gelagerte Fadenumlenkeinrichtung, eine Einrichtung zur Bildung eines Zwirn- oder Kablierpunktes, eine Einrichtung zur Beeinflussung der Ballonfadenspannung über die die Fadenballonform einstellbar ist sowie einen Regelkreis auf. Des Weiteren wird die Arbeitsstelle unter Verzicht auf eine Speicherscheibe betrieben und der Antrieb des Fadenballons erfolgt über einen festen Abwurfpunkt an einer rotierbaren Fadenumlenkeinrichtung, wobei der Regelkreis die Einrichtung zur Beeinflussung der Ballonfadenspannung derart regelt, dass sich stets eine minimale Fadenballongröße ergibt, wobei eine fest vorgegebene Abwurfgeometrie des Außenfadens sich aus dem festen Abwurfpunkt der Fadenumlenkeinrichtung ergibt, und sich auf Grund des festen Abwurfpunktes der Fadenumlenkeinrichtung und der erhöhten Fadenspannung im Bereich des festen Abwurfpunktes automatisch ein Abwurfwinkel des Außenfadens einstellt, der zu einer Minimierung des Durchmessers des sich ausbildenden freien Fadenballons führt.This object is achieved according to the invention by a method for operating a spindle at a work station of a double-wire twisting or cabling machine, in which an outer thread is drawn off from a supply spool and orbits the spindle in a thread balloon. The work station of the double-wire twisting or cabling machine has a bobbin, a rotatably mounted thread deflecting device, a device for forming a twisting or cabling point, a device for influencing the balloon thread tension via which the thread balloon shape can be adjusted, and a control loop. Furthermore, the work station is operated without a storage disk and the thread balloon is driven via a fixed ejection point on a rotatable thread deflection device, the control loop regulating the device for influencing the balloon thread tension in such a way that there is always a minimum thread balloon size, with a fixed predetermined one Throwing geometry of the outer thread results from the fixed dropping point of the thread deflecting device, and due to the fixed dropping point of the thread deflecting device and the increased thread tension in the area of the fixed dropping point, a dropping angle of the outer thread is automatically set, which leads to a minimization of the diameter of the free thread balloon being formed.
Die zugehörige Doppeldrahtzwirn- oder Kabliermaschine weist die im Anspruch 4 beschriebenen Merkmale auf.The associated double wire twisting or cabling machine has the features described in claim 4.
Vorteilhafte Ausführungsformen des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche 2 - 3.Advantageous embodiments of the method according to the invention are the subject of subclaims 2-3.
Vorteilhafte Ausführungsformen der zugehörigen Doppeldrahtzwirn- oder Kabliermaschine sind in den Unteransprüchen 5 - 13 beschrieben.Advantageous embodiments of the associated double-wire twisting or cabling machine are described in subclaims 5-13.
Das erfindungsgemäße Verfahren hat nicht nur den Vorteil, dass die Spindel während des Zwirn- oder Kablierprozesses auf Grund des im Durchmesser minimierten Fadenballons eine gute Energiebilanz aufweist, sondern der Verzicht während der gesamten Betriebsdauer auf jede Speicherung des Außenfadens führt auch zu einer sehr schonenden Behandlung des Fadenmaterials. Das bedeutet, der Verzicht auf den Einsatz einer Speicherscheibe generiert außer der Einsparung von zum Teil recht kostenintensiven Komponenten noch verschiedene weitere, nicht unerhebliche Vorteile.The method according to the invention not only has the advantage that the spindle has a good energy balance during the twisting or cabling process due to the thread balloon being minimized in diameter, but the omission of any storage of the outer thread during the entire operating time also leads to a very gentle treatment of the Thread material. This means that not using a storage disk generates various other, not inconsiderable advantages in addition to the saving of components, which can be quite expensive.
Die sich durch den Verzicht auf eine Speicherscheibe ergebende niedrigere Oberflächenvarianz führt beispielsweise zu verbesserten Rundlaufeigenschaften der Spindel und damit zu einem verbesserten Schwingungsverhalten dieses Bauelements.The lower surface variance resulting from the omission of a storage disk leads, for example, to improved concentricity properties of the spindle and thus to an improved vibration behavior of this component.
Des Weiteren wird durch den Verzicht auf eine Speicherscheibe die Gefahr von Wickelbildungen während des Zwirn- oder Kablierprozesses deutlich reduziert bzw. beseitigt. Schließlich wird durch den Verzicht auf eine Speicherscheibe die Zugängigkeit der Arbeitsstelle insgesamt verbessert, so dass im Bedarfsfall auch ein vereinfachter Austausch von Faden/Garn-Führungselementen möglich ist.Furthermore, by dispensing with a storage disc, the risk of winding formation during the twisting or cabling process is significantly reduced or eliminated. Finally, the lack of a storage disk improves the accessibility of the job as a whole, so that, if necessary, a simplified exchange of thread / yarn guide elements is also possible.
Das bedeutet, beim erfindungsgemäßen Verfahren wird nicht nur vermieden, dass es durch größeren Oberflächenkontakt des Fadenmaterials mit einer Speicherscheibe oder mit einem Ballonbegrenzungstopf zu Garnschädigungen kommen kann, sondern an der Form und der Größe des Durchmessers des die Spindel umrundenden Fadenballons ist auch leicht die jeweils herrschende Fadenspannung erkennbar, die bei Bedarf problemlos korrigiert werden kann.This means that the method according to the invention not only avoids that yarn damage due to greater surface contact of the thread material with a storage disc or with a balloon limiting pot, but also due to the shape and size of the diameter of the thread balloons surrounding the spindle, the prevailing one is also easy Thread tension recognizable, which can be easily corrected if necessary.
Vorteilhaft ist beim erfindungsgemäßen Verfahren des Weiteren, dass, im Gegensatz zum Einsatz einer Speicherscheibe, bei der eine ordnungsgemäße Fadenspeicherung durch Einstellen der korrekten Ballonspannung relativ schwierig ist, anhand des frei sichtbaren, die Spindel umkreisenden Fadenballons jederzeit leicht die jeweilige Ballonspannung erkennbar und über eine Einrichtung zur Beeinflussung der Ballonfadenspannung stets eine optimale Fadenballonform einstellbar ist.It is also advantageous in the method according to the invention that, in contrast to the use of a storage disk, in which proper thread storage by setting the correct balloon tension is relatively difficult, the respective thread balloons easily circling the spindle at any time Balloon tension can be recognized and an optimal thread balloon shape can always be set via a device for influencing the balloon thread tension.
Der Regelkreis regelt die Einrichtung zur Beeinflussung der Ballonfadenspannung so, dass sich automatisch eine minimale Fadenballongröße ergibt. Das bedeutet, durch diese Einrichtung zur Beeinflussung der Ballonfadenspannung wird die Zuführgeschwindigkeit des Fadens möglichst konstant gehalten, bzw. werden durch eine kontinuierliche Anpassung Schwankungen in der Lieferung des Fadens, die zu einem Bruch des Fadens oder zu Schwankungen bezüglich der Form und Größe des umlaufenden Fadenballons führen könnten, vermieden.The control loop regulates the device for influencing the balloon thread tension in such a way that a minimum thread balloon size is automatically obtained. This means that this device for influencing the balloon thread tension keeps the feeding speed of the thread as constant as possible, or, through continuous adaptation, fluctuations in the delivery of the thread, which lead to breakage of the thread or to fluctuations in the shape and size of the rotating thread balloon avoided.
In alternativer Ausführungsform ist allerdings auch vorstellbar, dass die rotierbar gelagerte Fadenumlenkeinrichtung als Umschlingungsbremse ausgebildet ist, bei der lediglich mit einem relativ geringen Fadenspeichervolumen gearbeitet wird.In an alternative embodiment, however, it is also conceivable that the rotatably mounted thread deflection device is designed as a wrap-around brake, in which only a relatively small thread storage volume is used.
Die Einrichtung zur Beeinflussung der Ballonfadenspannung steht vorzugsweise mit einem Regelkreis in Verbindung, der die Einrichtung der Art regelt, dass eine gewünschte Fadenballongröße einstellbar ist.The device for influencing the balloon thread tension is preferably connected to a control circuit which regulates the device in such a way that a desired thread balloon size can be set.
In einer vorteilhaften Ausführungsform regelt der Regelkreis außerdem beim Hoch- oder Runterfahren der Spindel sowie bei einer kurzfristigen Stromspannungsunterbrechung die Einrichtung zur Beeinflussung der Ballonfadenspannung derart, dass sich eine Fadenballongröße ergibt, bei der sowohl eine Berührung des feststehenden Spindeltopfes, als auch eine Berührung der zwischen den Arbeitsstellen angeordneten Separatoren vermieden wird.In an advantageous embodiment, the control loop also regulates the device for influencing the balloon thread tension when the spindle is raised or lowered and in the event of a short-term voltage voltage interruption in such a way that a thread balloon size results in which both a contact with the fixed spindle cup and a contact between the two Separators arranged at work stations is avoided.
Eine solche Ausbildung ermöglicht eine kompakte Bauweise der Arbeitsstellen mit einer gegenüber bekannten Doppeldrahtzwirn- oder Kabliermaschinen reduzierten Arbeitsstellenteilung, mit der Folge, dass der Platzbedarf der zum Aufstellen der erfindungsgemäß arbeitenden Doppeldrahtzwirn- oder Kabliermaschinen benötigt wird, verringert wird.Such a design enables a compact construction of the work stations with a reduced division of work stations compared to known double wire twisting or cabling machines, with the result that the space required for installing the double wire twisting or cabling machines according to the invention is reduced.
Wie vorstehend bereits im Zusammenhang mit dem erfindungsgemäßen Verfahren ausgeführt, weist die Doppeldrahtzwirn- oder Kabliermaschine eine Vielzahl von Arbeitsstellen auf, die jeweils eine Spindel, einen Spulentopf, eine rotier gelagerte Fadenumlenkeinrichtung, eine Einrichtung zur Bildung eines Zwirn- oder Kablierpunktes, eine Einrichtung zur Beeinflussung der Ballonfadenspannung über die die Fadenballonform einstellbar ist sowie einen Regelkreis aufweist. Des Weiteren ist die Arbeitsstelle ohne Speicherscheibe ausgestaltet und die rotierbar gelagerte Fadenumlenkeinrichtung weist einen festen Abwurfpunkt für den Außenfaden auf, wobei der Regelkreis so eingerichtet ist, dass die Einrichtung zur Beeinflussung der Ballonfadenspannung derart regelbar ist, dass sich stets eine minimale Fadenballongröße ergibt, wobei sich eine fest vorgegebene Abwurfgeometrie des Außenfadens aus dem festen Abwurfpunkt der Fadenumlenkeinrichtung ergibt, und sich auf Grund des festen Abwurfpunktes der Fadenumlenkeinrichtung und der erhöhten Fadenspannung im Bereich des festen Abwurfpunktes automatisch ein Abwurfwinkel des Außenfadens einstellt, der zu einer Minimierung des Durchmessers des sich ausbildenden freien Fadenballons führt.As already explained above in connection with the method according to the invention, the double-wire twisting or cabling machine has a large number of workstations, each of which has a spindle, a bobbin pot, a thread deflection device mounted in rotation, a device for forming a twisting or cabling point, and a device for influencing the balloon thread tension via which the thread balloon shape is adjustable and has a control loop. Furthermore, the work station is designed without a storage disc and the rotatably mounted thread deflection device has a fixed ejection point for the outer thread, the control loop being set up in such a way that the device for influencing the balloon thread tension can be regulated in such a way that there is always a minimal thread balloon size, which results in results in a fixed discharge geometry of the outer thread from the fixed discharge point of the thread deflection device, and due to the fixed discharge point of the thread deflection device and the increased thread tension in the area of the fixed discharge point, a discharge angle of the outer thread automatically arises, which minimizes the diameter of the free thread balloon being formed leads.
Eine solche Ausbildung hat nicht nur den Vorteil, dass wegen des Verzichtes auf eine Speicherscheibe oder einen mitrotierenden Ballonbegrenzungstopf weniger Komponenten pro Spindel erforderlich sind, sondern durch den festen Abwurfpunkt an der rotierbar gelagerten Fadenumlenkeinrichtung ist auch jederzeit eine ordnungsgemäße Rotation des Fadenballons sichergestellt.Such a design not only has the advantage that fewer components per spindle are required because there is no storage disc or a rotating balloon limiting pot, but due to the fixed ejection point on the rotatably mounted thread deflection device, proper rotation of the thread balloon is also ensured at all times.
In vorteilhafter Ausbildung kann der feste Abwurfpunkt an der rotierbar gelagerten Fadenumlenkeinrichtung verschiedene Ausführungsformen aufweisen.
Der feste Abwurfpunkt kann beispielsweise durch eine Öse gebildet werden, die im Außenbereich eines Zwirntellers oder im freien Endbereich eines Zwirnflügels angeordnet ist.
Bei einer anderen Ausführungsform wird der feste Abwurfpunkt durch den Ausgang eines geschlossenen Kanals gebildet, der sich vorzugsweise zwischen einer Fadenabgangsbohrung im Bereich der Drehachse der Spindel und dem Außenbereich eines Zwirntellers, oder zwischen einer Fadenabgangsbohrung im Bereich der Drehachse der Spindel und dem Endbereich eines Zwirnflügels erstreckt.In an advantageous embodiment, the fixed discharge point on the rotatably mounted thread deflection device can have different embodiments.
The fixed drop point can be formed, for example, by an eyelet which is arranged in the outer region of a twisting plate or in the free end region of a twisting wing.
In another embodiment, the fixed discharge point is formed by the exit of a closed channel, which preferably extends between a thread outlet bore in the region of the axis of rotation of the spindle and the outer region of a twist plate, or between a thread outlet bore in the region of the axis of rotation of the spindle and the end region of a twist wing .
In einer weiteren Ausführungsform ist vorgesehen, dass der feste Abwurfpunkt durch das Ende eines nach unten offenen Schlitzes gebildet wird, der zum Beispiel zwischen einer Fadenabgangsbohrung im Bereich der Drehachse der Spindel und dem Außenbereich eines Zwirntellers oder zwischen einer Fadenabgangsbohrung im Bereich der Drehachse der Spindel und dem Endbereich eines Zwirnflügels angeordnet ist.
In einer alternativen Ausführungsform ist außerdem vorgesehen, dass der feste Abwurfpunkt Bestandteil einer rotierbar gelagerten Umschlingungsbremse ist.
Eine solche Umschlingungsbremse weist vorzugsweise einen nabenartigen Grundkörper mit einer bezüglich der Drehachse der Spindel axial verlaufenden Fadenführungsbohrung und einer davon radial abgehenden Fadenabgangsbohrung auf. Außerdem verfügt die Umschlingungsbremse über einen an den Grundkörper angeschlossenen tellerförmigen Ansatz, der mit einem festen Abwurfpunkt für den Faden, vorzugsweise mit einer abriebfesten Öse, ausgestattet ist.
Eine derartige Ausbildung hat den Vorteil, dass durch eine solche Umschlingungsbremse stets auf einfache, zuverlässige Weise unmittelbar vor dem rotierenden Fadenballon nahezu konstante, zusätzliche Fadenspannung aufgebaut wird.In a further embodiment it is provided that the fixed discharge point is formed by the end of a slot which is open at the bottom and which, for example, is between a thread outlet bore in the region of the axis of rotation of the spindle and the outer region of a twist plate or between a thread outlet bore in the region of the axis of rotation of the spindle and the end region of a twine wing is arranged.
In an alternative embodiment it is also provided that the fixed discharge point is part of a rotatably mounted belt brake.
Such a wrap-around brake preferably has a hub-like base body with a thread guide bore running axially with respect to the axis of rotation of the spindle and a thread outlet bore extending radially therefrom. In addition, the wrap-around brake has a plate-shaped attachment connected to the base body, which is equipped with a fixed ejection point for the thread, preferably with an abrasion-resistant eyelet.
Such a design has the advantage that an additional constant thread tension is always built up in a simple, reliable manner directly in front of the rotating thread balloon by such a wrap brake.
Vorzugsweise sind die Zwirnteller, die Zwirnflügel und/oder die Umschlingungsbremse dabei so ausgebildet, dass sie selbsteinfädelnd sind. Das heißt, bei einem Neustart wird der Faden jeweils selbsttätig in den Abwurfpunkt der Fadenumlenkeinrichtung eingefädelt.
Die regelbare Einrichtung zur Beeinflussung der Ballonfadenspannung ist vorzugsweise entweder als Bremse ausgebildet, oder als aktives Lieferwerk ausgelegt.
Das bedeutet, der Fadenumlenkeinrichtung ist eine regelbare Vorrichtung zur Beeinflussung der Fadenspannung vorgeschaltet, durch die die Zufuhrgeschwindigkeit des Fadens so eingestellt wird, dass die Fadenspannung des in die Fadenumlenkeinrichtung eintretenden Fadens stets einen Wert aufweist, der den Durchmesser des die Spindel umkreisenden Fadenballons in Abhängigkeit von der Geometrie der Spindel minimiert, was einen positiven Einfluss auf den Energieverbrauch des Spindelantriebes hat.The twisting plates, the twisting wings and / or the wrapping brake are preferably designed in such a way that they are self-threading. That is, when you restart the thread is automatically threaded into the drop point of the thread deflecting device.
The controllable device for influencing the balloon thread tension is preferably designed either as a brake or as an active delivery mechanism.
This means that the thread deflection device is preceded by a controllable device for influencing the thread tension, by means of which the feed speed of the thread is adjusted so that the thread tension of the thread entering the thread deflection device always has a value which is a function of the diameter of the thread balloon orbiting the spindle minimizes the geometry of the spindle, which has a positive influence on the energy consumption of the spindle drive.

Die Arbeitsstelle 1 der Doppeldrahtzwirn- oder Kabliermaschine weist, wie üblich, ein in der Regel oberhalb oder hinter der Arbeitsstelle 1 positioniertes Gatter 4 auf, welches der Aufnahme wenigstens einer ersten Vorlagespulen 7 dient, von der ein so genannter Außenfaden 5 abgezogen wird.In the
The method according to the invention is also explained below on the basis of the illustrated work station 1.

Die Arbeitsstelle 1 verfügt außerdem über eine Spindel 2, die im vorliegenden Ausführungsbeispiel als so genannte Kablierspindel ausgebildet ist.
Die Spindel 2 weist einen Spulentopf 19 auf, in dem eine zweite Vorlagespule 15 gelagert ist, von der ein so genannter Innenfaden 16 über Kopf abgezogen wird, der einer oberhalb der Spindel 2 angeordneten Ballonöse oder einem so genannten Ausgleichssystem 9 zugeführt wird.
Der Spulentopf 19 ist auf der rotierbaren Fadenumlenkeinrichtung 20 gelagert, die im Ausführungsbeispiel der
Die Fadenumlenkeinrichtung 20 der Spindel 2 wird durch einen Spindelantrieb 3 beaufschlagt, bei dem es sich, wie im Ausführungsbeispiel, entweder um einen Direktantrieb oder um einen indirekten Antrieb handeln kann.

In der Ballonöse beziehungsweise im Ausgleichssystem 9 befindet sich der so genannte Kablier- oder auch Kordierpunkt, in dem die beiden Fäden, der Außenfaden 5 und der Innenfaden 16, zusammenlaufen und zum Beispiel einen Cordfaden 17 bilden.In the embodiment according to

Beim erfindungsgemäßen Verfahren kommt der Einrichtung 6 zur Beeinflussung der Fadenspannung die spezielle Aufgabe zu, die Fadenspannung des Außenfadens 5 vor der mit einem festen Abwurfpunkt 21 ausgestatteten Fadenumlenkeinrichtung 20 derart zu variieren, insbesondere zu erhöhen, dass sowohl auf eine Speicherscheibe, als auch auf einen mitrotierenden Ballonbegrenzungstopf, deren Einsatz zum Ausgleich von Unregelmäßigkeiten in der Fadenzufuhr bislang üblich ist, verzichtet werden kann.
Die durch die Einrichtung 6 auf den Außenfaden 5 aufgebrachte regelbare Fadenspannung weist vorzugsweise eine Größenordnung auf, die in Abhängigkeit von der Geometrie der Spindel 2 zu einer Minimierung des freien Fadenballons B führt.
Erreicht wird dies durch eine fest vorgegebene Abwurfgeometrie des Außenfadens 5, die sich aus dem festen Abwurfpunkt 21 der Fadenumlenkeinrichtung 20 ergibt.
Das heißt, auf Grund des festen Abwurfpunktes 21 der Fadenumlenkeinrichtung 20 und der erhöhten Fadenspannung stellt sich im Bereich des festen Abwurfpunktes 21 automatisch ein Abwurfwinkel des Außenfadens 5 ein, der zu einer Minimierung des Durchmessers des sich ausbildenden freien Fadenballons B führt.

Die Einrichtung 6 zur Beeinflussung der Fadenspannung kann entweder als elektronisch geregelte Bremse oder als aktives Lieferwerk ausgebildet sein. Auch eine Kombination der beiden vorgenannten Komponenten kann zum Einsatz kommen.
Als Ausgestaltungsvarianten des Lieferwerkes sind beispielsweise eine Galette, eine Fächerscheibe oder eine Antriebsrolle mit korrespondierender Druckrolle möglich. Wichtig ist, dass, um den freien Fadenballon B mit einem möglichst konstanten, minimierten Durchmesser aufrechtzuerhalten, durch die Einrichtung 6 stets eine aktive, regelbare Beeinflussung der Fadenspannung gegeben ist.
