Abstract

A travelling sensor chain (K) is guided past the work stations (P1- Pn) and contains a plurality of uniformly spaced travelling sensors (S1-SN). The division (T) of the travelling sensors is greater than that (t) of the work stations, and the distance from the first and last travelling sensors (S1,SN) to the first and last work stations (P1 or Pn respectively) is less than the division (T) of the travelling sensors. All the work stations (P1-Pn) can thereby be sensed in a relatively short monitoring cycle with a short displacement distance of the travelling sensor chain (K), and the time between the occurrence of a yarn break and its detection is drastically reduced, without the outlay in terms of cost being appreciably increased. <IMAGE>

Description

In der Textilindustrie gibt es eine ganze Anzahl von Produktionsmaschinen, auf denen an einer Vielzahl von Produktionsstellen gleichzeitig gearbeitet wird. Als Beispiele können Spinnmaschinen oder Zwirnmaschinen angeführt werden. Es besteht ein offensichtliches Bedürfnis, den Produktionsablauf an jeder einzelnen dieser Produktionsstellen automatisch zu überwachen, wobei vor allem eine Fadenbruchüberwachung erwünscht ist.There are a large number of production machines in the textile industry on which a large number of production sites are used at the same time. Examples are spinning machines or twisting machines. There is an obvious need to automatically monitor the production process at each of these production sites, with thread break monitoring being particularly desirable.

Eine derartige Ueberwachung ist an sich mit bekannten Mitteln technisch lösbar, indem beispielsweise jeder Faden an jeder Produktionsstelle einzeln überwacht wird. Aus Kostengründen sind jedoch derartige Lösungen, zumindest in grösserem Umfang, bisher nie realisiert worden. Denn die Vielzahl der Produktionsstellen erlaubt nur einen minimalen Kostenaufwand pro Produktionsstelle, damit der Aufwand pro Maschine in einem vertretbaren Rahmen bleibt.Such monitoring can be technically solved per se by known means, for example by monitoring each thread individually at each production site. For cost reasons, however, such solutions, at least on a larger scale, have never been implemented. The large number of production sites allows only a minimal cost per production site, so that the effort per machine remains within a reasonable range.

Auch wenn in den folgenden Ausführungen immer von "Faden" die Rede ist, so soll dieser Begriff nicht einschränkend, sondern als stellvertretend für alle Spinnereierzeugnisse, wie Garne, Zwirne, Filamente und dergleichen verstanden werden.Even if "thread" is always mentioned in the following explanations, this term is not intended to be restrictive, but as representative of all Spinning products such as yarns, threads, filaments and the like can be understood.

Die Erfindung betrifft eine Vorrichtung zur Ueberwachung von reihenförmig angeordneten Produktionsstellen an mehrspindligen Textilmaschinen, mit einem an den Produktionsstellen vorbeigeführten und an einem antreibbaren Träger befestigten Wandersensor zur Detektion des korrekten Fadenlaufs und/oder eines Fadenbruchs an der jeweiligen Produktionsstelle.The invention relates to a device for monitoring rows of production sites on multi-spindle textile machines, with a moving sensor that is guided past the production sites and attached to a drivable carrier for the detection of the correct yarn path and / or a yarn break at the respective production site.

Eine aus der CH-A-601 093 (=US-A-4 122 657) bekannte Vorrichtung dieser Art weist einen einzigen Wandersensor für eine Seite einer Ringspinnmaschine auf. Diese Lösung ist zwar kostenmässig sehr günstig und genügt auch den Anforderungen für die Aufnahme von Fadenbrüchen zu statistischen Zwecken. Wenn jedoch ein sogenannter Luntenstopp angesteuert werden soll, der bekanntlich nur wenige Sekunden nach einem Fadenbruch aktiv werden muss, dann genügt diese bekannte Vorrichtung den Anforderungen nicht mehr. Denn in der Regel ist die Zeit zwischen dem Auftreten eines Fadenbruchs und dessen Detektion durch den Wandersensor viel länger als die zulässigen wenigen Sekunden.A device of this type known from CH-A-601 093 (= US-A-4 122 657) has a single traveling sensor for one side of a ring spinning machine. This solution is very cheap in terms of cost and also meets the requirements for recording thread breaks for statistical purposes. However, if a so-called sliver stop is to be actuated, which is known to have to be activated only a few seconds after a thread break, then this known device no longer meets the requirements. Because usually the time between the occurrence of a thread break and its detection by the traveling sensor is much longer than the permitted few seconds.

Durch die Erfindung soll nun die bekannte Vorrichtung dahingehend verbessert werden, dass die Zeit zwischen dem Auftreten eines Fadenbruchs und dessen Detektion, die sogenannte Erfassungszeit, drastisch auf wenige Sekunden verkürzt wird, ohne dass der Kostenaufwand erheblich steigen würde.The aim of the invention is to improve the known device in such a way that the time between the occurrence of a thread break and its detection, the so-called detection time, is drastically reduced to a few seconds without the cost expenditure increasing significantly.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass an dem Träger eine Mehrzahl von Wandersensoren gleichmässig beabstandet angeordnet ist, dass die Teilung der Wandersensoren ein Mehrfaches der Teilung der Produktionsstellen beträgt, und dass der Abstand des ersten und des letzten Wandersensors von der ersten beziehungsweise letzten zu überwachenden Produktionsstelle kleiner ist als die Teilung der Wandersensoren.According to the invention, this object is achieved in that a plurality of hiking sensors are arranged on the carrier at an even distance from one another in that Division of the hiking sensors is a multiple of the division of the production points, and that the distance of the first and last hiking sensors from the first and last production point to be monitored is smaller than the division of the hiking sensors.

Die Erfassungszeit hängt von der Teilung, d. h. vom gegenseitigen Abstand der Wandersensoren ab, und diese wiederum ist eine Optimierungsfrage von einerseits möglichst kleiner Teilung und damit kurzer Erfassungszeit und anderseits möglichst wenig Sensoren und damit geringen Kosten. In der Praxis würde beispielsweise eine dem Abstand von 12 Produktionsstellen entsprechende Teilung gegenüber einem Sensor pro Produktionsstelle kostenmässig sehr günstig sein, und es wäre auch die Ansteuerung eines Luntenstopps noch sinnvoll, weil gegenüber der bekannten Vorrichtung mit nur einem Wandersensor und bei beispielsweise 240 Produktionsstellen die Erfassungszeit um über 95% reduziert wird.The acquisition time depends on the division, i. H. on the mutual distance of the hiking sensors, and this in turn is an optimization question of on the one hand the smallest possible division and thus short acquisition time and on the other hand as few sensors and thus low costs. In practice, for example, a division corresponding to the distance between 12 production sites would be very inexpensive compared to one sensor per production site, and it would also make sense to control a match stop, because compared to the known device with only one traveling sensor and, for example, 240 production sites, the acquisition time is reduced by over 95%.

Nachstehend wird die Erfindung anhand eines Ausführungsbeispiels und der einen schematischen Ausschnitt einer Ringspinnmaschine zeigenden einzigen Figur näher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment and the single figure showing a schematic section of a ring spinning machine.

Für die Beschreibung der erfindungsgemässen Vorrichtung wird das CH-Patent Nr. 601 903 und das dazu korrespondierende US-Patent Nr. 4 122 657 als bekannt vorausgesetzt, auf deren Offenbarung hiermit ausdrücklich Bezug genommen wird.For the description of the device according to the invention, CH Patent No. 601 903 and the corresponding US Patent No. 4 122 657 are assumed to be known, the disclosure of which is hereby expressly incorporated by reference.

In der Figur ist in schematischer Weise die Ringbank 1 einer Ringspinnmaschine mit n Produktionsstellen P1 bis Pn dargestellt, wobei n in der Praxis in der Grössenordnung von einigen hundert liegen kann. Längs der Ringbank 1 ist ein hin und her antreibbarer Träger 2 angeordnet, auf welchem Sensoren S1 bis SN für die Fadenbrucherfassung an den einzelnen Produktionsstellen P1 bis Pn befestigt sind. Der Träger 2 bildet zusammen mit den Sensoren S1 bis SN eine sogenannte Wandersensorkette K.In the figure, the ring bank 1 of a ring spinning machine with n production sites P1 to Pn is shown schematically, where n can in practice be of the order of a few hundred. A back and forth drivable carrier 2 is arranged along the ring bench 1, on which sensors S1 to SN for thread breakage detection are attached at the individual production points P1 to Pn. The carrier 2 forms, together with the sensors S1 to SN, a so-called hiking sensor chain K.

Die Teilung T der Wandersensorkette K, d.h. der Abstand zwischen zwei benachbarten Sensoren S entspricht der sechsfachen Teilung t der Produktionsstellen P. Darstellungsgemäss liegt der erste Sensor S1 an der ersten Produktionsstelle P1, der zweite Sensor S2 an der siebten Produktionsstelle P7, und so weiter; und der letzte Sensor SN liegt an der Produktionsstelle Pn-5. Wenn die Wandersensorkette K um eine Produktionsstelle (Teilung t) nach rechts bewegt wird, dann liegt der erste Sensor S1 an der Produktionsstelle P2 und der letzte Sensor SN an der Produktionsstelle Pn-4. Nach insgesamt fünf Arbeitstakten der Wandersensorkette K - ausgehend von der dargestellten Ausgangslage - liegt der erste Sensor S1 an der Produktionsstelle P6 und der letzte Sensor SN an der letzten Produktionsstelle Pn. Dann sind sämtliche Produktionsstellen einmal abgetastet worden.The pitch T of the hiking sensor chain K, i.e. the distance between two adjacent sensors S corresponds to the sixfold division t of the production sites P. As shown, the first sensor S1 is located at the first production site P1, the second sensor S2 is located at the seventh production site P7, and so on; and the last sensor SN is at the production site Pn-5. If the traveling sensor chain K is moved to the right by one production point (division t), then the first sensor S1 is located at the production point P2 and the last sensor SN at the production point Pn-4. After a total of five work cycles of the traveling sensor chain K - starting from the illustrated starting position - the first sensor S1 is located at the production site P6 and the last sensor SN at the last production site Pn. Then all production sites have been scanned once.

Die Wandersensorkette K hat ihre Endstellung erreicht und kann nun wieder nach links in die dargestellte Ausgangslage zurückbewegt werden (Leertakt). Anschliessend wird der beschriebene Zyklus wiederholt, usw. Selbstverständlich könnten auch bei der Rückwärtsbewegung der Wandersensorkette K die Produktionsstellen abgetastet werden. Dann würde also diese Rückwärtsbewegung ebenfalls fünf Arbeitstakte aufweisen.The hiking sensor chain K has reached its end position and can now be moved back to the left into the starting position shown (idle cycle). The cycle described is then repeated, etc. Of course, the production points could also be scanned when the traveling sensor chain K moves backward. Then this backward movement would also have five work cycles.

Es ist also möglich, durch eine Verschiebung der Wandersensorkette um fünf Teilungen t der Produktionsstellen den gesamten Produktionsstellenbereich zu erfassen.It is therefore possible to cover the entire production area by shifting the hiking sensor chain by five divisions t of the production sites.

Die Erfassungszeit eines Fadenbruchs ist eine Frage der Statistik. Im günstigsten Fall, nämlich dann, wenn der Fadenbruch genau dann auftritt, wenn die betreffende Produktionsstelle gerade von einem Sensor überwacht wird, ist sie gleich Null. Der ungünstigste Fall ist dann gegeben, wenn der Sensor die betreffende Produktionsstelle unmittelbar vor dem Fadenbruch verlassen hat. denn dann kann der Sensor den Fadenbruch erst nach insgesamt fünf Arbeitstakten nach rechts und einem Leertakt nach links detektieren.The detection time of a thread break is a question of statistics. In the best case, namely when the thread break occurs exactly when the production site in question is currently being monitored by a sensor, it is zero. The worst case is when the sensor has left the relevant production site immediately before the thread break. because then the sensor can only detect the thread break after a total of five work cycles to the right and one idle cycle to the left.

Die Teilung T der Wandersensoren S kann auch höher sein als 6 Teilungen t der Produktionsstellen P und kann in der Praxis beispielsweise auf 12 Teilungen t erhöht werden, was die Kosten beträchtlich reduziert. Dabei liegt die Erfassungszeit immer noch in einem für einen Luntenstopp ausreichenden Rahmen.The pitch T of the hiking sensors S can also be higher than 6 pitches t of the production sites P and can in practice be increased to 12 pitches t, for example, which considerably reduces the costs. The acquisition time is still in a sufficient range for a match stop.

Wie schon eingangs erwähnt wurde, wird bezüglich der Art der Sensoren S, der Anbringung der Wandersensorkette K an der Ringbank 1 und ihres Antriebs und bezüglich der Art der entstehenden Signale und deren Uebertragung auf die CH-A-601 093 (=US-A-4 122 657) verwiesen, wo alle diese Einzelheiten ausführlich beschrieben sind.As has already been mentioned at the beginning, with regard to the type of sensors S, the attachment of the traveling sensor chain K to the ring bank 1 and their drive, and with regard to the type of signals generated and their transmission to CH-A-601 093 (= US-A- 4 122 657) where all these details are described in detail.

Die elektrischen Anschlüsse der einzelnen Sensoren S müssten im Prinzip von der Wandersensorkette K einzeln herausgeführt werden. Es ist aber auch mög­ lich, in jedem Sensor S dessen Signale so aufzuarbeiten, dass sie in geeigneter Form an ein Bussystem abgegeben oder, wie in einem Schieberegister, in der Wandersensorkette K verschoben werden. Weitere Beispiele liessen sich anfügen. Da diese aber in der Elektronik hinlänglich bekannt sind, sollen sie hier nicht weiter beschrieben werden.In principle, the electrical connections of the individual sensors S would have to be led out individually by the traveling sensor chain K. But it is also possible Lich to process the signals in each sensor S in such a way that they are sent in a suitable form to a bus system or, as in a shift register, are shifted in the traveling sensor chain K. Further examples could be added. However, since these are well known in electronics, they will not be described further here.

Für den elektrischen Anschluss der Wandersensorkette K sind also nur wenige elektrische Verbindungen, und zwar im Minimum deren zwei, erforderlich. Diese beiden Verbindungen können durch die für die Bewegung der Wandersensorkette K erforderlichen beiden Seile 3 und 4 hergestellt werden, die in diesem Fall elektrisch leitend sein müssen.For the electrical connection of the traveling sensor chain K, only a few electrical connections are required, and at least two of them. These two connections can be made by the two ropes 3 and 4 required for the movement of the traveling sensor chain K, which in this case must be electrically conductive.

Aehnlich wie bei der in dem genannten CH-Patent beschriebenen Vorrichtung, sind die Seile 3 und 4 zu angetriebenen Aufrollmitteln 5 bzw. 6 geführt, wobei jedoch nur noch eine dem Verstellweg der Wandersensorkette K entsprechende Seillänge der Länge T-t aufgewickelt werden muss. Diese beträgt bei einer Teilung T=12t etwa einen Meter, verglichen mit etwa 30 Metern und mehr bei der in dem genannten CH-Patent beschriebenen Vorrichtung.Similar to the device described in the cited Swiss patent, the ropes 3 and 4 are guided to driven retraction means 5 and 6, but only a rope length of length T-t corresponding to the adjustment path of the hiking sensor chain K has to be wound up. With a pitch T = 12t, this is approximately one meter, compared to approximately 30 meters and more in the device described in the cited Swiss patent.

Anstatt die Seillänge von etwa 1 m auf das jeweilige Aufrollmittel 5 oder 6 aufzuwickeln, kann darstellungsgemäss die aufzuwickelnde Seillänge auch in einem kleinen Flaschenzug 7 oder 8 gespeichert werden. Dies hat den Vorteil, dass die elektrischen Anschlüsse von den Seilenden 9 bzw. 10 abgenommen werden können, wogegen beim Aufwickeln der Seillänge auf die Aufrollmittel 5, 6 die elektrischen Anschlüsse über Schleifringe geführt werden müssen (siehe CH-A-601 093).Instead of winding the rope length of about 1 m onto the respective winding means 5 or 6, the rope length to be wound can also be stored in a small pulley 7 or 8 as shown. This has the advantage that the electrical connections can be removed from the rope ends 9 and 10, whereas when winding the rope length onto the reeling means 5, 6 the electrical connections have to be made via slip rings (see CH-A-601 093).
