Definitions
- the present invention relates to a method for monitoring contacts of a rotating component of a textile machine, in particular a clothing roller of a card, for example a carding drum, with another component of the textile machine, wherein the two components are connected to an electrical energy source, but usually are isolated from each other electrically and only in the case of contact of the two components, a short circuit is generated, which is detected by a monitoring device and a corresponding textile machine.
- a generic device and a corresponding method is described.
- a spinning preparation machine in particular a card, carding or the like, are for monitoring and / or adjustment of distances and components in which a garnished, rapidly rotating roller at least one garnished and / or non-garnished component opposite and the distance between the opposing components is changeable, electrically isolated from each other.
- these components are connected to an electrical circuit, in which there is a measuring element for contact detection.
- the garnished, rapidly rotating roller is, for example, a carding drum, wherein the opposing, garnished and / or non-garnished component are, for example, a doffer roller, cover or a shuttering segment-containing shuttering segment.
- This carding nip is very narrow and may, for example, change during operation of the machine due to heating of the components. This can lead to contacts between the rapidly rotating roller and the opposite component. Such contacts should be avoided as far as possible.
- a disadvantage of this solution is that every single tooth of the clothing with the opposite component generates a single contact and thus increases the number of contacts.
- the technical implementation of this proposal is extremely complex.
- each individual thread needle must be monitored for their potential in order to determine the number of contacts can. Otherwise, a determination of the number or amount of contacts would not be possible, since even a short contact with this garniturbe timesen component would also indicate a single contact, as a permanent contacting of the two components over several clothing tips away. This very inaccurate or otherwise very complex determination of the number of contacts is hardly feasible in practice.
- Object of the present invention is therefore to enable a simple and particularly effective monitoring of contacts of each other approximated components of a textile machine to make appropriate conclusions about the further operation of the textile machine can.
- the method according to the invention serves to monitor contacts of the rotating component of a textile machine, in particular a clothing roller of a carding machine, for example a carding drum, with a further component of the textile machine.
- the Both components are connected to an electrical energy source. In general, that is, when the two components are not in contact with each other, they are electrically isolated from each other. Only in the case of contact of the two components, a short circuit is generated, which is detected by a monitoring device.
- the invention it is not the number of individual short circuits that is detected, but the duration of individual short circuits per unit of time, and combined to form a total duration of all short circuits per unit of time.
- This has the significant advantage that a kind of quality assessment can be made with regard to an actual risk of damage to the textile machine due to excessive contacts. If only individual, short and few contacts take place between the two opposing components, then as a rule no danger to the machine is to be expected. Such short contacts can arise, for example, if fiber contaminants, such as small metal parts between the two opposing components briefly adhere and then dissolve again and promoted from the machine. Even if individual teeth of the clothing or sets generate a short-term contact, so they usually grind again within a very short time, so that in future no further contact thereof is generated.
- the particular advantage of the invention is that even with opposing Garniturzähnen these do not need to be detected individually to determine the number of contacts, but it can be provided with only one Gegenpol the individual components in each case. This leads to a short circuit, even if a large number of contact points occur in this component.
- the present invention can thus be used particularly advantageously in, for example, a card drum and the card drum opposite, garnished flat bars or garnished rolls.
- the present invention can be used when the garnished rotating carding drum is a planar component, for example, a shield or guide opposite. In all these cases, regardless of the number of contacts, the contact duration is to be determined in order to allow particularly effective monitoring with regard to a potential danger to the textile machine.
- the duration of one revolution of the rotating component or a part or a multiple of this revolution duration is used as the time unit which is used to assess the duration of individual short circuits or the total duration of all short circuits. It can be determined in this way that there is a specific contact duration per revolution of the card drum, for example. Exceeds this contact duration a predetermined allowable contact time, so appropriate measures, such as the shutdown of the textile machine or the adjustment of the distance of the opposing components can be caused.
- a quotient per se is formed from the total duration of the short circuits per unit of time and the time unit per se. This quotient, which states that at a high value, a long-lasting contacting of the components has taken place and at a low value, this duration of contacting was rather low, can be used for the monitoring device or an appropriately associated evaluation as a measure of action to be taken.
- the quotient of the total duration of the short circuits per unit time and the time unit per se is advantageously to be used as a measure of the quality of the setting of the textile machine.
- a low value of this quotient indicates a particularly good setting of the textile machine, where, when the quotient is zero, the distance between the opposing components may be too large.
- the value of this quotient is very high, this indicates that the gap between the opposing components is too small, too long a contact takes place and this results in a risk to the machine.
- An acceptable value for the quality of Adjustment of the textile machine and corresponding quotient may result from the experience of the operator of the textile machine or from the nature of the opposing and monitored components.
- a slightly higher quotient can be accepted for clothing wires, which are made pliable, while for fixed baffles or solid all-steel sets, the value must be lower to exclude damage.
- An advantageous measure when exceeding a predetermined total duration of the short circuits of a unit of time and / or the value of the quotient of the total duration and the time unit per se can advantageously consist in that the rotating and / or the further component is machined, in particular by grinding. By grinding a very fine decrease of the material can take place, whereby a very fine adjustment of the opposing components can be done.
- An advantageous other or additional measure in case of exceeding the duration of individual short circuits and / or the total duration of all short circuits per unit time and / or the quotient may be that the distance between the rotating and the further component is increased.
- the duration of individual short circuits and / or the total duration of all short circuits per unit time and / or the quotient of the total duration of all short circuits per unit time and the time unit per se is displayed on a display device.
- the operator of the textile machine is able to initiate a suitable measure for setting the machine, if the corresponding value is unsatisfactory.
- the rotating and / or the further component along an axis of the rotating component in several divided electrically isolated from each other, axial sections.
- the short circuits in these sections are then recorded separately.
- these isolated sections can be independently analyzed for contact duration.
- measures to be taken are easier to locate. For example, it is possible to determine that the sag of the stationary component is too great if a longer contact duration takes place in the middle of the stationary component than in the lateral areas.
- an adjustment of the sag of the component or a machining of the component take place only in the central region.
- a textile machine is suitable for carrying out the above-mentioned method.
- it has a clothing roller of a card, for example a carding drum, which is arranged with a further component of the textile machine, which is spaced apart with a small gap, for example a carding nip.
- the two components are connected to an electrical energy source. As long as they are spaced apart, the two components are electrically isolated from each other. Only in the case of contact of the two components creates a short circuit, which can be detected by a monitoring device.
- the monitoring device is integrated into the circuit, for example, which connects the two components in the event of a short circuit or contact, and indicates that there is a current flow or a short circuit.
- the monitoring device is designed to record the duration of individual short circuits and to combine them into a total duration of all short circuits per unit of time. Accordingly, the monitoring device is able to add up the duration of the individual short circuits per unit of time, in order thus to determine a total value of the short circuits or contacts in this time unit.
- This total duration of all short circuits is independent of the number, ie how often contacts per unit time have occurred. But the decisive factor is how long a total contact has taken place per unit of time, or in other words how long no contact per unit of time has taken place is done.
- this total duration has the value zero, so if the gap between the rotating member and the other component is so large that they do not touch.
- the total duration of the contacts is as large as the time unit per se, then a permanent contact or a permanent short circuit takes place. This indicates that there is always contact somewhere between the opposing components.
- Cause can be compared to the prior art, either a very high number of individual contacts or even a single contact, which is just constantly present throughout the time unit.
- the number of individual contacts does not matter in the present invention.
- Here alone is decisive how long a total contact exists, even if this contact duration results from a high number of individual contacts or even from a single contact. If too long a short circuit or contact / e, so according to the present invention, a corresponding measure to improve the quality of the operation of the textile machine is initiated. There is thus a significant difference between the present invention and the prior art.
- the further component is a stationary, a rotating or alternatively a component moving along the surface of the rotating first component.
- the further component can thus be, for example, either a baffle as a stationary component, or a rotating, garnished doffer roll. It is also possible that the further component is a flat bar guided along the surface of the card drum and moves accordingly.
- the rotating component is advantageously associated with a speed sensor, such as a pulse generator or angular position sensor.
- This speed sensor is capable of one Time unit, which refers to the rotation of the rotating member, in particular the card drum to specify.
- the suitable time unit is then, for example, one revolution of the card drum so that, for example, unevenness in the card drum can be detected very easily. Alternatively, a fraction of this revolution or a multiple of this revolution can be used as a suitable unit of time.
- the textile machine can also be assigned a device for detecting the revolutions or the position of the rotating component by means of pattern recognition.
- the pattern of not or only insignificantly changed punctures or short circuits is recognized from one revolution to the next and evaluated for the detection of individual revolutions.
- the textile machine comprises a rotating and / or the further component, which along an axis of the rotating member, d. H. is divided transversely to the circumferential direction of the rotating component into a plurality of mutually electrically insulated, axial sections.
- a separate detection of short circuits in each section is possible.
- sags or contacts occurring only in individual areas or sections can thus be better localized and individually eliminated.
- a slack of the other component not the entire distance between the rotating component and the other component must be changed, but it is possible to eliminate the slack, for example by changing the slack or by local processing of the other component or the rotating component ,
- each axial section is assigned a separate power supply and / or a separate monitoring device. As a result, it is very easy to determine the section which has generated a short circuit or contact via the local short circuits.
- a display device for displaying the duration of all short circuits per unit time is present in the textile machine. If the textile machine is equipped with different axial sections in an advantageous embodiment, then it may also be advantageous to display the section in the display device in which a short circuit has occurred. As a result, the corresponding section can be more easily located by a machine control or by the operator of the textile machine.
- an automatic adjustment device is provided in order to be able to independently change the distance between the rotating component and the further component when a predetermined duration of the short circuits is exceeded per unit of time.
- This automatic adjustment can be done either by an operator or by the machine control. Elaborate manual adjustments and in particular a standstill for manual adjustments can be avoided.
- FIG. 1 shows in a schematic representation of the side view of a known Wanderdeckelkarde 1.
- fiber flakes 2 are taken over by a licker-3 as Wattenvorlage and handed over to a card drum 4.
- Lapturer 3 and card drum 4 are each related to clothing wires, not shown here.
- At least the card drum 4 is associated with an unillustrated speed sensor, for example a pulse generator or angular position sensor or a device for detecting the revolutions or the position of the rotating component by means of pattern recognition.
- the flakes are dissolved on the card drum 4, cleaned and parallelized. This process is done by the interaction of card drum 4 in different stationary other components 7, 8, 9, 10.
- a traveling cover unit 5 is arranged, which has individual moving lid 6 and flat bars.
- the revolving lids 6 are guided by the revolving flat unit 5 counter to the direction of rotation of the carding drum 4 along part of the circumference of the carding drum 4.
- the stationary working elements consist of, for example, carding elements 7, knives 8 and guide or cover elements 9, 10.
- the fibers form on the card drum 4 a non-woven fabric, which is removed from a doffer roll 11 and in a conventional manner in a, consisting of different rolls discharge section 12 is formed into a card sliver 13. This card sliver 13 is then deposited by a sliver tray (not shown) in a transport can.
- the stationary working elements 7, 8, 9, 10 and the revolving lid 6 or flat bars and the doffer roller 11 represent according to parlance of the present application, the other components, which interact with the card drum 4, which is the rotating member.
- FIG. 2 schematically a stationary Kardierelement 7 is shown, which cooperates with a card pulley 4 shown in part.
- the carding element 7 has a clothing 15, which is opposite to a drum set 16. Between the clothing 15 and the drum set 16, a gap S is provided. As a rule, it is to be ensured that the clothing 15 and the drum clothing 16 do not touch one another, but have a very narrow, substantially narrower spacing than that shown here in the schematic example.
- a contact element 17 is arranged in the Kardierelement 7.
- the contact elements 17 and 18 are each conductively connected to the clothing 15 and the drum set 16. Once the clothing 15 and the drum set 16 each other Touch, creates an electrical connection between the contact element 17 and the contact element 18th
- FIG. 3 is a schematic and exemplary of the other components, an electrical connection between the card pulley 4 and the other component, the doffer roller 11, shown.
- Card pulley 4 and pickup roller 11 are connected to a power source 20 via an electrical line.
- the gap S is sufficiently large, no energy transfer and thus no short circuit between the card drum 4 and the pickup roller 11.
- the two components 4 and 11 come into contact, because either an electrically conductive material has passed between the two components, or because the gap S, for example, due to a thermal expansion of the components 4, 11 goes to zero, creates a short circuit, which is detected in a monitoring device 21.
- a display device 22 which indicates the short circuit, for example, based on a measurement protocol or on the duration of the short circuit or the duration of all short circuits per unit time or a quotient thereof.
- an operator of the textile machine can take appropriate measures to avoid damage to the textile machine, such as the revolving flat card 1 shown here.
- an adjusting device 23 is shown, which can optionally be used in the present invention.
- the adjusting device 23 receives, for example, from the monitoring device 21, or also manually by the operator of the textile machine, a signal with which the distance of the doffer roller 11 of the card drum 4 and thus the gap S between the two components can be changed. As a result, a rapid, possibly also automatic reaction to a too long contacting of the two rotating components is to be avoided.
- the device shown here is of course also on the other, other components 6, 7, 8, 9,10 FIG. 1 mutatis mutandis applicable.
- FIG. 4 is shown in a schematic representation of another embodiment of the present invention.
- a rotating carding drum 4 shown in front view cooperates with another component, here for example a cover element 10.
- the cover element 10 is subdivided into three different, mutually electrically insulated sections 10a, 10b and 10c. Each section 10a, 10b and 10c is associated with a monitoring device 21a, 21b and 21c. As soon as a short circuit occurs in a section 10a, 10b or 10c, the monitoring device 21a, 21b or 21c detects this short circuit and forwards this information to the display device 22.
- the display device 22 can distinguish between the respective sections 10a, 10b or 10c, in which section 10a, 10b or 10c a contacting and thus a short circuit has taken place. Either via automatic adjustment devices or via manual intervention or mechanical processing, the distance in the corresponding section can be corrected in a targeted manner. A particularly fine adjustment of the gap S between the cover 10 and the card drum 4 is thus possible.
- the device shown here is of course also on the other, other components 6, 7, 8, 9,10 FIG. 1 mutatis mutandis applicable.
- FIG. 5 an example of a measurement protocol of the short circuits is shown.
- the short circuits in a time unit T are thus determined in terms of their duration.
- an appropriate measure is taken to increase the gap S again and thus generate fewer short circuits.
- the measure can also take place with a predetermined time offset, ie only when the contact duration t remains unacceptably long over a predetermined longer period of time, the appropriate measure is initiated. If, after a short time, this total duration t of the contacts or short circuits changes again or if the value of the quotient Q decreases again after this predetermined time and moves into a permissible range, the action is dispensed with.
- the present invention is not limited to the illustrated embodiments. In particular, it is applicable to various textile machines as well as to various components of these textile machines.

Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Überwachen von Kontakten eines sich drehenden Bauteils einer Textilmaschine, insbesondere einer Garniturwalze einer Karde, zum Beispiel einer Kardentrommel, mit einem weiteren Bauteil der Textilmaschine, wobei die beiden Bauteile mit einer elektrischen Energiequelle verbunden werden, aber in der Regel elektrisch voneinander isoliert sind und nur im Falle eines Kontaktes der beiden Bauteile ein Kurzschluss erzeugt wird, der von einer Überwachungseinrichtung erfasst wird sowie eine entsprechende Textilmaschine.The present invention relates to a method for monitoring contacts of a rotating component of a textile machine, in particular a clothing roller of a card, for example a carding drum, with another component of the textile machine, wherein the two components are connected to an electrical energy source, but usually are isolated from each other electrically and only in the case of contact of the two components, a short circuit is generated, which is detected by a monitoring device and a corresponding textile machine.

Nachteilig bei dieser Lösung ist es, das jeder einzelne Zahn der Garnitur mit dem gegenüberliegenden Bauteil einen einzelnen Kontakt erzeugt und damit die Zahl der Kontakte erhöht. Die technische Ausführung dieses Vorschlags ist äußerst aufwändig. So muss insbesondere bei einem der garnierten Kardentrommel gegenüberliegenden, ebenfalls mit einer Garnitur versehenen Bauteil, jede einzelne Garniturnadel auf ihr Potenzial hin überwacht werden um die Anzahl der Kontakte feststellen zu können. Ansonsten wäre eine Ermittlung der Anzahl bzw. Menge der Kontakte nicht möglich, da bereits ein kurzer Kontakt mit diesem garniturbelegten Bauteil ebenso einen einzelnen Kontakt anzeigen würde, wie eine ständige Kontaktierung der beiden Bauteile über mehrere Garniturspitzen hinweg. Diese sehr ungenaue oder andernfalls sehr aufwändige Ermittlung der Anzahl der Kontakte ist in der Praxis kaum realisierbar.A disadvantage of this solution is that every single tooth of the clothing with the opposite component generates a single contact and thus increases the number of contacts. The technical implementation of this proposal is extremely complex. Thus, in particular with one of the garnished carded drum opposite, also provided with a set component, each individual thread needle must be monitored for their potential in order to determine the number of contacts can. Otherwise, a determination of the number or amount of contacts would not be possible, since even a short contact with this garniturbelegten component would also indicate a single contact, as a permanent contacting of the two components over several clothing tips away. This very inaccurate or otherwise very complex determination of the number of contacts is hardly feasible in practice.
Aufgabe der vorliegenden Erfindung ist es daher, eine einfache und besonders wirkungsvolle Überwachung von Kontakten zueinander angenäherter Bauteile einer Textilmaschine zu ermöglichen, um entsprechende Rückschlüsse auf den weiteren Betrieb der Textilmaschine treffen zu können.Object of the present invention is therefore to enable a simple and particularly effective monitoring of contacts of each other approximated components of a textile machine to make appropriate conclusions about the further operation of the textile machine can.
Die Aufgabe wird mit den Merkmalen der unabhängigen Patentansprüche gelöst.The object is achieved with the features of the independent claims.
Das erfindungsgemäße Verfahren dient zum Überwachen von Kontakten des sich drehenden Bauteils einer Textilmaschine, insbesondere einer Garniturwalze einer Karde, zum Beispiel einer Kardentrommel, mit einem weiteren Bauteil der Textilmaschine. Die beiden Bauteile werden mit einer elektrischen Energiequelle verbunden. In der Regel, d. h., wenn die beiden Bauteile keinen Kontakt miteinander haben, sind sie elektrisch voneinander isoliert. Nur im Falle eines Kontaktes der beiden Bauteile wird ein Kurzschluss erzeugt, der von einer Überwachungseinrichtung erfasst wird.The method according to the invention serves to monitor contacts of the rotating component of a textile machine, in particular a clothing roller of a carding machine, for example a carding drum, with a further component of the textile machine. The Both components are connected to an electrical energy source. In general, that is, when the two components are not in contact with each other, they are electrically isolated from each other. Only in the case of contact of the two components, a short circuit is generated, which is detected by a monitoring device.
Erfindungsgemäß wird nicht die Anzahl einzelner Kurzschlüsse, sondern die Dauer einzelner Kurzschlüsse pro Zeiteinheit erfasst und zu einer Gesamtdauer sämtlicher Kurzschlüsse pro Zeiteinheit zusammengefasst. Dies hat den wesentlichen Vorteil, dass eine Art Qualitätsbeurteilung erfolgen kann, hinsichtlich einer tatsächlichen Gefährdung einer Beschädigung der Textilmaschine durch übermäßige Kontakte. Finden nämlich nur einzelne, kurze und wenige Kontakte zwischen den beiden sich gegenüberstehenden Bauteilen statt, so ist in der Regel keine Gefährdung der Maschine zu erwarten. Derartige kurze Kontakte können beispielsweise entstehen, wenn Faserverunreinigungen, beispielsweise kleine Metallteile zwischen den beiden gegenüberstehenden Bauteilen kurzzeitig anhaften und sich anschließend wieder lösen und aus der Maschine gefördert werden. Auch wenn einzelne Zähne der Garnitur bzw. Garnituren einen kurzzeitigen Kontakt erzeugen, so schleifen sich diese in der Regel innerhalb kürzester Zeit wieder ab, so dass künftig kein weiterer Kontakt hiervon erzeugt wird. Wird allerdings beispielsweise durch eine übermäßige Erwärmung der Kardentrommel ein lang andauernder Kontakt zwischen den beiden gegenüberstehenden Bauteilen erzeugt, so ist das eine unter Umständen massive Gefährdung der Maschine. So kann beispielsweise bei einer lang andauernden Zeitspanne der Kurzschlüsse darauf zurückgeschlossen werden, dass eine höhere Gefahr für die Maschine besteht, als bei nur kurzzeitigen Kontakten bzw. Kurzschlüssen pro Zeiteinheit.According to the invention, it is not the number of individual short circuits that is detected, but the duration of individual short circuits per unit of time, and combined to form a total duration of all short circuits per unit of time. This has the significant advantage that a kind of quality assessment can be made with regard to an actual risk of damage to the textile machine due to excessive contacts. If only individual, short and few contacts take place between the two opposing components, then as a rule no danger to the machine is to be expected. Such short contacts can arise, for example, if fiber contaminants, such as small metal parts between the two opposing components briefly adhere and then dissolve again and promoted from the machine. Even if individual teeth of the clothing or sets generate a short-term contact, so they usually grind again within a very short time, so that in future no further contact thereof is generated. If, however, a long-lasting contact between the two opposing components is generated, for example, by excessive heating of the card drum, this may be a massive threat to the machine. Thus, for example, in the case of a long-lasting period of short circuits, it can be concluded that there is a higher risk for the machine than with only short-term contacts or short-circuits per unit of time.
Der besondere Vorteil der Erfindung besteht auch darin, dass auch bei einander gegenüberstehenden Garniturzähnen diese nicht einzeln erfasst werden müssen, um die Anzahl der Kontakte festzustellen, sondern es können die einzelnen Bauteile jeweils mit nur einem Gegenpol versehen sein. dies führt zu einem Kurzschluss, auch wenn eine Vielzahl von Kontaktstellen in diesem Bauteil auftreten. Die vorliegende Erfindung ist somit besonders vorteilhaft einsetzbar bei beispielsweise einer Kardentrommel und der Kardentrommel gegenüberliegenden, garnierten Deckelstäben oder garnierten Walzen. Ebenso ist die vorliegende Erfindung einsetzbar, wenn der garnierten, sich drehenden Kardentrommel ein flächiges Bauteil, beispielsweise eine Abschirm- oder Leiteinrichtung gegenüber steht. In allen diesen Fällen ist unabhängig von der Anzahl der Kontakte die Kontaktdauer zu ermitteln um daraus eine besonders effektive Überwachung im Hinblick auf ein Gefährdungspotenzial der Textilmaschine zu ermöglichen.The particular advantage of the invention is that even with opposing Garniturzähnen these do not need to be detected individually to determine the number of contacts, but it can be provided with only one Gegenpol the individual components in each case. This leads to a short circuit, even if a large number of contact points occur in this component. The present invention can thus be used particularly advantageously in, for example, a card drum and the card drum opposite, garnished flat bars or garnished rolls. Likewise, the present invention can be used when the garnished rotating carding drum is a planar component, for example, a shield or guide opposite. In all these cases, regardless of the number of contacts, the contact duration is to be determined in order to allow particularly effective monitoring with regard to a potential danger to the textile machine.
In einer vorteilhaften Ausführung der Erfindung wird als Zeiteinheit, welche für die Beurteilung der Dauer einzelner Kurzschlüsse bzw. der Gesamtdauer sämtlicher Kurzschlüsse herangezogen wird, die Dauer einer Umdrehung des sich drehenden Bauteils oder ein Teil oder ein Vielfaches von dieser Umdrehungsdauer verwendet. Es kann auf diese Art und Weise festgestellt werden, dass pro Umdrehung der beispielsweise Kardentrommel eine bestimmte Kontaktdauer vorliegt. Überschreitet diese Kontaktdauer eine vorbestimmte zulässige Kontaktdauer, so können entsprechende Maßnahmen, wie beispielsweise das Abstellen der Textilmaschine oder das Verstellen des Abstandes der sich gegenüberliegenden Bauteile veranlasst werden.In an advantageous embodiment of the invention, the duration of one revolution of the rotating component or a part or a multiple of this revolution duration is used as the time unit which is used to assess the duration of individual short circuits or the total duration of all short circuits. It can be determined in this way that there is a specific contact duration per revolution of the card drum, for example. Exceeds this contact duration a predetermined allowable contact time, so appropriate measures, such as the shutdown of the textile machine or the adjustment of the distance of the opposing components can be caused.
Vorteilhaft ist es, wenn aus der Gesamtdauer der Kurzschlüsse pro Zeiteinheit und der Zeiteinheit an sich ein Quotient gebildet wird. Dieser Quotient, welcher besagt, dass bei einem hohen Wert eine lang andauernde Kontaktierung der Bauteile erfolgt ist und bei einem niedrigen Wert diese Dauer der Kontaktierung eher gering war, kann für die Überwachungseinrichtung oder einer entsprechend zugeordneten Auswerteeinrichtung als Maß für zu ergreifenden Maßnahmen herangezogen werden.It is advantageous if a quotient per se is formed from the total duration of the short circuits per unit of time and the time unit per se. This quotient, which states that at a high value, a long-lasting contacting of the components has taken place and at a low value, this duration of contacting was rather low, can be used for the monitoring device or an appropriately associated evaluation as a measure of action to be taken.
Der Quotient aus der Gesamtdauer der Kurzschlüsse pro Zeiteinheit und der Zeiteinheit an sich ist vorteilhafterweise als ein Maß für die Qualität der Einstellung der Textilmaschine heranzuziehen. So kann es durchaus akzeptabel sein, dass ein niedriger Wert dieses Quotienten auf eine besonders gute Einstellung der Textilmaschine hinweist, wo hingehend wenn der Quotient Null ist, der Abstand zwischen den einander gegenüberliegenden Bauteilen möglicherweise zu groß ist. Ist der Wert dieses Quotienten allerdings sehr hoch, weist dies darauf hin, dass der Spalt zwischen den einander gegenüberliegenden Bauteilen zu gering ist, dass zu lange eine Kontaktierung erfolgt und hieraus eine Gefahr für die Maschine herausgeht. Ein akzeptabler Wert für die Qualität der Einstellung der Textilmaschine und dementsprechenden Quotienten kann sich aus der Erfahrung des Betreibers der Textilmaschine oder aus der Art der einander gegenüberstehenden und überwachten Bauteile ergeben. So kann beispielsweise ein etwas höherer Quotient akzeptiert werden bei Garniturdrähten, welche nachgiebig ausgestaltet sind, während bei feststehenden Leitwänden oder festen Ganzstahlgarnituren der Wert niedriger sein muss, um eine Beschädigung auszuschließen.The quotient of the total duration of the short circuits per unit time and the time unit per se is advantageously to be used as a measure of the quality of the setting of the textile machine. Thus, it may well be acceptable that a low value of this quotient indicates a particularly good setting of the textile machine, where, when the quotient is zero, the distance between the opposing components may be too large. However, if the value of this quotient is very high, this indicates that the gap between the opposing components is too small, too long a contact takes place and this results in a risk to the machine. An acceptable value for the quality of Adjustment of the textile machine and corresponding quotient may result from the experience of the operator of the textile machine or from the nature of the opposing and monitored components. Thus, for example, a slightly higher quotient can be accepted for clothing wires, which are made pliable, while for fixed baffles or solid all-steel sets, the value must be lower to exclude damage.
Eine vorteilhafte Maßnahme bei Überschreitung einer vorgegebenen Gesamtdauer der Kurzschlüsse einer Zeiteinheit und/oder des Wertes des Quotienten aus der Gesamtdauer und der Zeiteinheit an sich kann vorteilhafterweise darin bestehen, dass das sich drehende und/oder das weitere Bauteil spanend, insbesondere durch schleifen bearbeitet wird. Durch das Schleifen kann eine sehr feine Abnahme des Materials erfolgen, wodurch eine sehr feine Einstellung der einander gegenüberliegenden Bauteile erfolgen kann.An advantageous measure when exceeding a predetermined total duration of the short circuits of a unit of time and / or the value of the quotient of the total duration and the time unit per se can advantageously consist in that the rotating and / or the further component is machined, in particular by grinding. By grinding a very fine decrease of the material can take place, whereby a very fine adjustment of the opposing components can be done.
Ein vorteilhafte andere oder zusätzliche Maßnahme bei einer Überschreitung der Dauer einzelner Kurzschlüsse und/oder der Gesamtdauer sämtlicher Kurzschlüsse pro Zeiteinheit und/oder des Quotienten kann darin bestehen, dass der Abstand zwischen dem sich drehenden und dem weiteren Bauteil vergrößert wird. Hierbei ist jedoch stets darauf zu achten, dass die Qualität des zu bearbeitenden Fasermaterials hierunter nicht übermäßig leidet, da in der Regel ein besonders enger Kardierspalt eine bessere Kardierqualität erzeugt als ein größerer Kardierspalt.An advantageous other or additional measure in case of exceeding the duration of individual short circuits and / or the total duration of all short circuits per unit time and / or the quotient may be that the distance between the rotating and the further component is increased. Here, however, always make sure that the quality of the fiber material to be processed hereunder does not suffer excessively, since usually a particularly narrow carding produces a better carding quality than a larger carding gap.
Vorzugsweise wird die Dauer einzelner Kurzschlüsse und/oder die Gesamtdauer sämtlicher Kurzschlüsse pro Zeiteinheit und/oder der Quotient aus der Gesamtdauer sämtlicher Kurzschlüsse pro Zeiteinheit und der Zeiteinheit an sich an einer Anzeigeeinrichtung angezeigt. Der Bediener der Textilmaschine ist hierbei in der Lage eine geeignete Maßnahme zur Einstellung der Maschine einzuleiten, falls der entsprechende Wert unbefriedigend ist.Preferably, the duration of individual short circuits and / or the total duration of all short circuits per unit time and / or the quotient of the total duration of all short circuits per unit time and the time unit per se is displayed on a display device. The operator of the textile machine is able to initiate a suitable measure for setting the machine, if the corresponding value is unsatisfactory.
In einer besonders vorteilhaften Ausbildung der Erfindung wird das sich drehende und/oder das weitere Bauteil entlang einer Achse des sich drehenden Bauteils in mehrere voneinander elektrisch isolierte, axiale Abschnitte unterteilt. Die Kurzschlüsse in diesen Abschnitten werden sodann separat voneinander erfasst. Insbesondere bei den feststehenden Bauteilen ist es sehr einfach möglich, diese abschnittsweise, quer zur Drehrichtung des sich drehenden Bauteils voneinander zu isolieren. Diese voneinander isolierten Abschnitte können unabhängig voneinander hinsichtlich ihrer Kontaktdauer analysiert werden. Auf diese Weise sind Maßnahmen, welche zu ergreifen sind, leichter zu lokalisieren. So ist es beispielsweise möglich festzustellen, dass der Durchhang des feststehenden Bauteils zu groß ist, wenn in der Mitte des feststehenden Bauteils eine längere Kontaktdauer erfolgt als in den Seitenbereichen. In diesem Beispiel kann als mögliche Maßnahme eine Einstellung des Durchhangs des Bauteils oder eine spanende Bearbeitung des Bauteils nur im mittleren Bereich erfolgen.In a particularly advantageous embodiment of the invention, the rotating and / or the further component along an axis of the rotating component in several divided electrically isolated from each other, axial sections. The short circuits in these sections are then recorded separately. In particular, with the fixed components, it is very easy to isolate these sections, transverse to the direction of rotation of the rotating component from each other. These isolated sections can be independently analyzed for contact duration. In this way, measures to be taken are easier to locate. For example, it is possible to determine that the sag of the stationary component is too great if a longer contact duration takes place in the middle of the stationary component than in the lateral areas. In this example, as a possible measure, an adjustment of the sag of the component or a machining of the component take place only in the central region.
Eine erfindungsgemäße Textilmaschine ist zur Durchführung des oben genannten Verfahrens geeignet. Sie weist insbesondere eine Garniturwalze einer Karde, zum Beispiel eine Kardentrommel auf, welches mit einem weiteren Bauteil der Textilmaschine, das mit einem geringen Spalt, zum Beispiel einem Kardierspalt, beabstandet angeordnet ist. Die beiden Bauteile sind mit einer elektrischen Energiequelle verbunden. Solange sie voneinander beabstandet sind, sind die beiden Bauteile elektrisch voneinander isoliert. Nur im Falle eines Kontaktes der beiden Bauteile entsteht ein Kurzschluss, welcher mit einer Überwachungseinrichtung erfasst werden kann.A textile machine according to the invention is suitable for carrying out the above-mentioned method. In particular, it has a clothing roller of a card, for example a carding drum, which is arranged with a further component of the textile machine, which is spaced apart with a small gap, for example a carding nip. The two components are connected to an electrical energy source. As long as they are spaced apart, the two components are electrically isolated from each other. Only in the case of contact of the two components creates a short circuit, which can be detected by a monitoring device.
Die Überwachungseinrichtung ist beispielsweise in den Stromkreis, welcher im Falle eines Kurzschlusses bzw. Kontaktes die beiden Bauteile miteinander verbindet, integriert und zeigt an, dass ein Stromfluss bzw. ein Kurzschluss vorliegt. Die Überwachungseinrichtung ist dazu ausgelegt, die Dauer einzelner Kurzschlüsse zu erfassen und zu einer Gesamtdauer sämtlicher Kurzschlüsse pro Zeiteinheit zusammenzufassen. Die Überwachungseinrichtung ist dementsprechend in der Lage, die Dauer der einzelnen Kurzschlüsse pro Zeiteinheit zu addieren, um somit einen Gesamtwert der Kurzschlüsse bzw. Kontakte in dieser Zeiteinheit zu ermitteln. Diese Gesamtdauer sämtlicher Kurzschlüsse ist unabhängig von der Anzahl, d. h. wie oft Kontakte pro Zeiteinheit erfolgt sind. Allein entscheidend ist, wie lange insgesamt ein Kontakt pro dieser Zeiteinheit stattgefunden hat oder anders ausgedrückt, wie lange kein Kontakt pro Zeiteinheit erfolgt ist. So kann es im ersten Extremfall sein, dass diese Gesamtdauer den Wert Null aufweist, wenn also der Spalt zwischen dem drehenden Bauteil und dem anderen Bauteil so groß ist, dass sie sich nicht berühren. Im anderen Fall, wenn die Gesamtdauer der Kontakte ebenso groß ist, wie die Zeiteinheit an sich, so findet ein Dauerkontakt bzw. ein Dauerkurzschluss statt. Dies deutet darauf hin, dass ständig irgendwo zwischen den einander gegenüberstehenden Bauteilen ein Kontakt stattfindet. Ursache kann, verglichen mit dem Stand der Technik, entweder eine sehr hohe Anzahl einzelner Kontakte oder auch nur ein einziger Kontakt sein, welcher eben ständig während der gesamten Zeiteinheit vorhanden ist.The monitoring device is integrated into the circuit, for example, which connects the two components in the event of a short circuit or contact, and indicates that there is a current flow or a short circuit. The monitoring device is designed to record the duration of individual short circuits and to combine them into a total duration of all short circuits per unit of time. Accordingly, the monitoring device is able to add up the duration of the individual short circuits per unit of time, in order thus to determine a total value of the short circuits or contacts in this time unit. This total duration of all short circuits is independent of the number, ie how often contacts per unit time have occurred. But the decisive factor is how long a total contact has taken place per unit of time, or in other words how long no contact per unit of time has taken place is done. So it may be in the first extreme case that this total duration has the value zero, so if the gap between the rotating member and the other component is so large that they do not touch. In the other case, if the total duration of the contacts is as large as the time unit per se, then a permanent contact or a permanent short circuit takes place. This indicates that there is always contact somewhere between the opposing components. Cause can be compared to the prior art, either a very high number of individual contacts or even a single contact, which is just constantly present throughout the time unit.
Die Anzahl der einzelnen Kontakte, wie sie im Stand der Technik als wesentliche erachtet wird, spielt bei der vorliegenden Erfindung keine Rolle. Hier ist alleine ausschlaggebend wie lange insgesamt ein Kontakt vorliegt, auch wenn sich diese Kontaktdauer aus einer hohen Anzahl einzelner Kontakte oder auch nur aus einem einzigen Kontakt ergibt. Liegt zu lange ein Kurzschluss bzw. Kontakt/e vor, so wird nach der vorliegenden Erfindung eine entsprechende Maßnahme zur Verbesserung der Qualität der Arbeitsweise der Textilmaschine eingeleitet. Darin besteht somit ein wesentlicher Unterschied zwischen der vorliegenden Erfindung und dem Stand der Technik.The number of individual contacts, as considered essential in the prior art, does not matter in the present invention. Here alone is decisive how long a total contact exists, even if this contact duration results from a high number of individual contacts or even from a single contact. If too long a short circuit or contact / e, so according to the present invention, a corresponding measure to improve the quality of the operation of the textile machine is initiated. There is thus a significant difference between the present invention and the prior art.
In einer vorteilhaften Textilmaschine ist das weitere Bauteil ein feststehendes, ein sich drehendes oder alternativ ein sich entlang der Oberfläche des sich drehenden ersten Bauteils bewegendes Bauteil. Das weitere Bauteil kann somit beispielsweise entweder ein Leitblech als ein feststehendes Bauteil sein, oder eine sich drehende, garnierte Abnehmerwalze sein. Ebenso ist es möglich, dass das weitere Bauteil ein entlang der Oberfläche der Kardentrommel geführter Deckelstab ist und sich dementsprechend bewegt. Grundsätzlich kann jedes sich dem drehenden Bauteil, insbesondere der Kardentrommel gegenüberliegendes Bauteil, welches in engem Abstand zu dem sich drehenden Bauteil angeordnet sein soll, dieses weitere Bauteil sein. Durch die Überwachungseinrichtung kann der geeignete Abstand der beiden Bauteile ermittelt werden.In an advantageous textile machine, the further component is a stationary, a rotating or alternatively a component moving along the surface of the rotating first component. The further component can thus be, for example, either a baffle as a stationary component, or a rotating, garnished doffer roll. It is also possible that the further component is a flat bar guided along the surface of the card drum and moves accordingly. In principle, each of the rotating component, in particular the card drum opposite component, which should be arranged in close proximity to the rotating component, this further component. By the monitoring device, the suitable distance of the two components can be determined.
Dem sich drehendem Bauteil ist vorteilhafterweise ein Drehzahlsensor, z.B. ein Impulsgeber oder Winkellagegeber zugeordnet. Dieser Drehzahlsensor ist in der Lage eine Zeiteinheit, welche sich auf die Umdrehung des sich drehenden Bauteiles, insbesondere der Kardentrommel bezieht, vorzugeben. Die geeignete Zeiteinheit ist dann beispielsweise eine Umdrehung der Kardentrommel, so dass beispielsweise Unebenheiten in der Kardentrommel sehr einfach erfasst werden können. Alternativ kann auch ein Bruchteil dieser Umdrehung oder ein Vielfaches dieser Umdrehung als geeignete Zeiteinheit herangezogen werden.The rotating component is advantageously associated with a speed sensor, such as a pulse generator or angular position sensor. This speed sensor is capable of one Time unit, which refers to the rotation of the rotating member, in particular the card drum to specify. The suitable time unit is then, for example, one revolution of the card drum so that, for example, unevenness in the card drum can be detected very easily. Alternatively, a fraction of this revolution or a multiple of this revolution can be used as a suitable unit of time.
Der Textilmaschine kann in einer weiteren vorteilhaften Ausführung auch eine Einrichtung zur Erfassung der Umdrehungen bzw. der Lage des sich drehenden Bauteils mittels Mustererkennung zugeordnet sein. Dabei wird das Muster der nicht oder nur unwesentlich veränderten Durchschläge bzw. Kurzschlüsse von einer Umdrehung zur nächsten erkannt und für die Erkennung einzelner Umdrehungen ausgewertet.In a further advantageous embodiment, the textile machine can also be assigned a device for detecting the revolutions or the position of the rotating component by means of pattern recognition. In this case, the pattern of not or only insignificantly changed punctures or short circuits is recognized from one revolution to the next and evaluated for the detection of individual revolutions.
In einer weiteren Ausführung der vorliegenden Erfindung ist vorteilhafterweise vorgesehen, dass die Textilmaschine ein sich drehendes und/oder das weitere Bauteil aufweist, welches entlang einer Achse des sich drehenden Bauteils, d. h. quer zur Umfangsrichtung des sich drehenden Bauteils in mehrere, voneinander elektrisch isolierte, axiale Abschnitte unterteilt ist. Hierdurch ist ein separates Erfassen der Kurzschlüsse in dem jeweiligen Abschnitt möglich. Insbesondere Durchhänge oder nur in einzelnen Bereichen bzw. Abschnitten auftretende Kontaktierungen können somit besser lokalisiert und individuell beseitigt werden. So muss beispielsweise bei einem Durchhang des weiteren Bauteils nicht der gesamte Abstand zwischen sich drehenden Bauteil und dem weiteren Bauteil verändert werden, sondern es ist möglich den Durchhang, beispielsweise durch Veränderung des Durchhanges oder durch lokale Bearbeitung des weiteren Bauteils oder des sich drehenden Bauteils zu beseitigen.In a further embodiment of the present invention, it is advantageously provided that the textile machine comprises a rotating and / or the further component, which along an axis of the rotating member, d. H. is divided transversely to the circumferential direction of the rotating component into a plurality of mutually electrically insulated, axial sections. As a result, a separate detection of short circuits in each section is possible. In particular, sags or contacts occurring only in individual areas or sections can thus be better localized and individually eliminated. For example, in a slack of the other component not the entire distance between the rotating component and the other component must be changed, but it is possible to eliminate the slack, for example by changing the slack or by local processing of the other component or the rotating component ,
Um die einzelnen axialen Abschnitte separat auszuwerten zu können, ist es vorteilhaft, wenn jedem axialen Abschnitt eine separate Energieversorgung und/oder eine separate Überwachungseinrichtung zugeordnet ist. Hierdurch ist über die lokalen Kurzschlüsse sehr einfach der Abschnitt festzustellen, welcher einen Kurzschluss bzw. Kontakt erzeugt hat.In order to evaluate the individual axial sections separately, it is advantageous if each axial section is assigned a separate power supply and / or a separate monitoring device. As a result, it is very easy to determine the section which has generated a short circuit or contact via the local short circuits.
Vorteilhafterweise ist in der Textilmaschine eine Anzeigeeinrichtung zur Anzeige der Dauer aller Kurzschlüsse pro Zeiteinheit vorhanden. Ist die Textilmaschine in einer vorteilhaften Ausgestaltung mit unterschiedlichen axialen Abschnitten ausgestattet, so kann es auch vorteilhaft sein, den Abschnitt in der Anzeigeeinrichtung anzeigen zu lassen, in welchem ein Kurzschluss erfolgt ist. Hierdurch kann der entsprechende Abschnitt leichter durch eine Maschinensteuerung oder durch den Bediener der Textilmaschine lokalisiert werden.Advantageously, a display device for displaying the duration of all short circuits per unit time is present in the textile machine. If the textile machine is equipped with different axial sections in an advantageous embodiment, then it may also be advantageous to display the section in the display device in which a short circuit has occurred. As a result, the corresponding section can be more easily located by a machine control or by the operator of the textile machine.
In einer besonders vorteilhaften Ausführung der Textilmaschine ist eine automatische Einstelleinrichtung vorgesehen, um bei Überschreitung einer vorbestimmten Dauer der Kurzschlüsse pro Zeiteinheit selbstständig den Abstand zwischen dem sich drehenden und dem weiteren Bauteil verändern zu können. Diese automatische Einstelleinrichtung kann entweder von einem Bediener oder von der Maschinensteuerung getätigt werden. Aufwändige manuelle Einstellarbeiten und insbesondere ein Stillstand für die manuellen Einstellarbeiten kann hierdurch vermieden werden.In a particularly advantageous embodiment of the textile machine, an automatic adjustment device is provided in order to be able to independently change the distance between the rotating component and the further component when a predetermined duration of the short circuits is exceeded per unit of time. This automatic adjustment can be done either by an operator or by the machine control. Elaborate manual adjustments and in particular a standstill for manual adjustments can be avoided.
