Abstract

In the device described, a traction element (22) is joined to the yarn (6) to be controlled. A coupling (38) links the traction element (22) to a lifting device (32). The coupling (38) includes a link pin (40) which can reciprocate batween a neutral position and a coupling position and which works in conjunction with two piezoelectric switching elements (50, 52) each of which acts alternately as an actuator and a sensor. This not only ensures that the coupling construction is extremely simple but also enables the switching function of the coupling to be monitored, thus avoiding switching faults.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention

Die Figuren 1, 2, 3a, 3b und 3c zeigen ein erstes Ausführungsbeispiel der erfindungsgemässen Steuervorrichtung 2 an einer Webmaschine 4. Die nur schematisch dargestellte Webmaschine enthält Kettfäden 6, die mittels der Steuervorrichtung 2 zur Bildung eines offenen Faches 8 in Hochstellung 6a oder Tiefstellung 6b gebracht werden können. Durch das offene Fach 8 wird ein Schussfaden 10 eingetragen und mittels eines Webblattes 12 an der Anschlagkante 14 angeschlagen. Das so hergestellte Gewebe 16 wird über eine Warenabzugsvorrichtung 18 abgezogen.Figures 1, 2, 3a, 3b and 3c show a first embodiment of the control device 2 according to the invention a weaving machine 4. The weaving machine shown only schematically contains warp threads 6 by means of the control device 2 to form an open compartment 8 in the up position 6a or Subscript 6b can be brought. Through the open compartment 8, a weft thread 10 is inserted and by means of a Reed 12 struck on the stop edge 14. That so Fabric 16 is manufactured via a goods take-off device 18 deducted.

Die Steuervorrichtung 2 enthält einen ortsfesten Block 20, in dem ein Zugorgan 22 auf- und abgehend geführt ist. Das lamellenartig ausgebildete Zugorgan 22 ist am unteren Ende über ein Verbindungselement 24, beispielsweise ein Zugseil mit einer Litze 26 verbunden, die ein Litzenauge 28 enthält, durch das der Kettfaden 6 geführt ist. Mittels einer Rückzugfeder 30 ist die Litze 26 und damit auch das Zugorgan 22 nach unten vorgespannt. Eine Hubvorrichtung 32 mit beidseits der Lamelle angeordneten Hubmessern 34 wirkt mit einem Antriebsnocken 36 zusammen, der am Zugorgan 22 angeordent ist. Die Ausbildung und der Antrieb der Hubvorrichtung 32 und der Hubmesser 34 ist hinlänglich bekannt, so dass auf eine nähere Beschreibung verzichtet werden kann. Mittels der Rückzugfeder 30 wird das Zugorgan 22 nach unten vorgespannt, d.h. in die Tiefstellung 6b des Kettfadens 6. Um den Kettfaden 6 in die Hochstellung 6a zu bringen und zu halten, heben die Hubmesser 34 das Zugorgan 22 über den Antriebs nocken 36 soweit an, bis die Hochstellung 6a des Kettfadens 6 erreicht ist. Eine Kupplungsvorrichtung 38 dient zum Halten des Zugorganes 22 in der angehobenen Stellung oder zur Freigabe, so dass das Zugorgan 22 unter dem Einfluss der Rückzugfeder beim Absenken des Hubmessers diesem folgen kann.The control device 2 contains a stationary block 20, in which a tension member 22 is guided up and down. The lamellar trained tension member 22 is at the lower end a connecting element 24, for example a pull rope with a Strand 26 connected, which contains a strand eye 28 through which the warp thread 6 is guided. By means of a return spring 30 is the strand 26 and thus also the tension member 22 down biased. A lifting device 32 with the slat on both sides arranged lifting knives 34 acts with a drive cam 36 together, which is arranged on the tension member 22. Training and the drive of the lifting device 32 and the lifting knife 34 is well known, so that a more detailed description can be dispensed with. By means of the return spring 30 Tension member 22 biased downwards, i.e. to the subscript 6b of the warp thread 6. Around the warp thread 6 in the up position To bring and hold 6a, the lifting knives 34 lift the Tension member 22 on the drive cam 36 until the Superscript 6a of the warp thread 6 is reached. A coupling device 38 serves to hold the tension member 22 in the raised position or release, so that the tension member 22 under the influence of the return spring when lowering the Hubmessers can follow this.

Die Kupplungsvorrichtung 38 weist einen beidseits des Zugorganes 22 im Block 20 hin- und hergehend verschiebbar gelagerten Kupplungsstift 40 auf. Der Kupplungsstift 40 enthält einen schmalen Führungsabschnitt 42, der in einen Längsschlitz 44 des Zugorganes eingreift und die auf- und abwärtsgerichtete Bewegung des Zugorganes unter gleichzeitiger Führung desselben gestattet. Weiter enthält der KupplungsStift einen breiten Kupplungsabschnitt 46, der in eine Kupplungsausnehmung 48 im Zugorgan einrasten kann und in dieser Position das Führungsorgan in der eingenommenen Stellung, die der Hochstellung des Kettfadens 6 entspricht, halten kann.The coupling device 38 has one on both sides of the traction element 22 slidably mounted back and forth in block 20 Coupling pin 40 on. The coupling pin 40 contains a narrow guide section 42 that fits into a longitudinal slot 44 of the tension member engages and the upward and downward Movement of the traction element under simultaneous Leadership of the same is permitted. The coupling pin also contains a wide coupling section 46 that fits into a coupling recess 48 can snap into the tension member and in this Position the governing body in the position it took corresponds to the raising of the warp thread 6, can hold.

Zur hin- und hergehenden Bewegung, d.h. zur Steuerung des Kupplungsstiftes dienen zwei piezoelektrische Schaltglieder 50,52, die beidseits des Kupplungsstiftes am Block 20 angeordnet sind und mit den Enden des Kupplungsstiftes zusammenwirken. Die piezoelektrischen Schaltglieder 50,52 wirken wechselweise als Aktuator und als Sensor.For back and forth movement, i.e. to control the Coupling pin serve two piezoelectric switching elements 50,52, arranged on both sides of the coupling pin on block 20 are and cooperate with the ends of the coupling pin. The piezoelectric switching elements 50, 52 act alternately as an actuator and as a sensor.

Die Funktionsweise des Kupplungsstiftes und der Schaltglieder 50,52 ist anhand der Figur 1 und insbesondere anhand der schematischen Figuren 3a bis 3c noch näher erläutert. Bei stromlosen Schaltgliedern 50,52 nimmt der Kupplungsstift 40 die in Figur 3a gezeigte Grundstellung ein, in der der schmale Führungsabschnitt 42 in den Längsschlitz 44 des Zugorganes 22 eingreift. Der Kupplungsstift steht dabei an einem Schaltglied 52 an und erzeugt einen gewissen Druck auf dieses Schaltglied, das dadurch als Sensor wirkt und einen Stromimpuls an eine nicht näher dargestellte elektronische Steuereinheit abgibt und dadurch anzeigt, in welcher Stellung sich der Kupplungsstift befindet. Zum Schalten des Kupplungsstiftes wird eines der Schaltglieder, beispielsweise das rechte Schaltglied 52 mit Strom beaufschlagt, wodurch sich das piezoelektrische Schaltglied krümmt und dabei den Kupplungsstift aus der rechten Stellung in die linke Stellung verschiebt, so dass der breite Kupplungsabschnitt 46 des Kupplungsstiftes in die Kupplungsausnehmung 48 des Zugorganes 22 einrastet und damit eine weitere Bewegung des Zugorganes verhindert. Bei diesem Schaltvorgang wird der Kupplungsstift gegen das andere Schaltglied 50 gedrückt, wie aus Figur 3b hervorgeht und erzeugt dort einen Steuerstrom, der wiederum der nicht näher dargestellten elektronischen Steuereinheit die eingenommene Stellung des Kupplungsstiftes anzeigt. Die eingenommene Stellung des Kupplungsstiftes, in der das Zugorgan 22 in der Hochstellung arretiert ist, bleibt solange erhalten, bis ein weiterer Steuerimpuls das linke Schaltglied 50 veranlasst, den Kupplungsstift in die Ausgangslage zurückzudrücken, wie dies aus Figur 3c hervorgeht, in der der schmale Führungsabschnitt 42 wiederum mit dem Längsschlitz 44 des Zugorganes zusammenwirkt. Die piezoelektrische Schaltglieder 50,52 wirken also wechselweise einerseits als Aktuatoren, die ein Verschieben des Kupplungsstiftes bewirken, und anderseits als Sensoren, die die korrekt eingenommene Stellung des Kupplungsstiftes der elektronischen Steuereinheit anzeigen. The operation of the coupling pin and the switching elements 50, 52 is based on FIG. 1 and in particular on the basis of FIG schematic figures 3a to 3c explained in more detail. At de-energized switching elements 50, 52 take the coupling pin 40 the basic position shown in Figure 3a, in which the narrow Guide section 42 in the longitudinal slot 44 of the tension member 22 engages. The coupling pin is on a switching element 52 and creates a certain pressure on it Switching element, which thereby acts as a sensor and a current pulse to an electronic control unit, not shown emits and thereby indicates in which position the coupling pin is located. For switching the coupling pin becomes one of the switching elements, for example the right one Switching element 52 is supplied with current, as a result of which piezoelectric switching element bends and the coupling pin shifted from the right position to the left position, so that the wide coupling portion 46 of the coupling pin into the coupling recess 48 of the tension member 22 engages and thus a further movement of the traction element prevented. During this shift, the clutch pin pressed against the other switching element 50, as in Figure 3b emerges and generates a control current there, which in turn the electronic control unit, not shown indicates the position occupied by the coupling pin. The assumed position of the coupling pin, in which the Tension member 22 is locked in the high position remains as long received until another control pulse the left switching element 50 causes the coupling pin to be pushed back into the starting position, as can be seen from Figure 3c, in which the narrow guide section 42 again with the longitudinal slot 44 of the tension member cooperates. The piezoelectric switching elements 50.52 act alternately on the one hand as actuators, which cause the coupling pin to move, and on the other hand, as sensors that detect the correct position the coupling pin of the electronic control unit Show.

Die Figur 4 zeigt die Weiterbildung der Steuervorrichtung der Figuren 1 bis 3 am Beispiel einer Doppelhubvorrichtung, wie sie beispielsweise in der US-PS 3 835 894 beschrieben ist. Bei dieser Steuervorrichtung sind zwei Zugorgane 22a,22b sowie eine Hubvorrichtung 32a mit zwei Paar gegeneinander wirkenden Hubmessern 34a und 34b vorhanden. Die Zugorgane 22a und 22b sind über eine Verbindungsseil 54 miteinander verbunden, welches über eine Umlenkrolle 56 geführt ist. An der Achse 58 der Umlenkrolle 56 ist eine Lagergabel 60 angeschlossen, an der das flexible Verbindungselement 24 befestigt ist, welches die Verbindung zur Litze 26 und damit zum Kettfaden 6 herstellt. Die Funktionsweise des DoppelhubSystems ist bekannt und die Steuerung erfolgt analog dem Beispiel der Figuren 1 bis 3c.Figure 4 shows the development of the control device of the Figures 1 to 3 using the example of a double lifting device, such as for example, it is described in U.S. Patent No. 3,835,894. In this control device there are two traction elements 22a, 22b and a lifting device 32a with two pairs against each other acting lifting knives 34a and 34b. The traction elements 22a and 22b are connected to one another via a connecting cable 54, which is guided over a deflection roller 56. At the A bearing fork 60 is connected to the axis 58 of the deflection roller 56, to which the flexible connecting element 24 is attached is which the connection to the strand 26 and thus to the Warp thread 6 produces. How the double-stroke system works is known and the control is done analogously Example of Figures 1 to 3c.

Wie aus Figur 5 hervorgeht, können ein oder mehrere Kupplungsvorrichtungen 38 und entsprechende Zugorgane 22 in einer modularen Einheit 62 zusammengefasst sein, die über Verbindungsmittel 64, z.B. Schwalbenschwanzverbindung, mit entsprechenden modularen Einheiten 62,62a,62b,62c,62d verbunden sein können. Die einzelnen Schaltglieder 50,52 sind an Leitungen 66,68 bzw. 70,72 angeschlossen, die an Kontaktstellen 74,76 bzw. 78,80 münden, die mit entsprechenden Kontaktstellen angeschlossener modularer Einheiten 62,62a,62b, 62c,62d zusammenwirken. Die Leitungen 66,68,70,72 bilden eine Matrix zur Steuerung der Schaltglieder 50,52.As can be seen from Figure 5, one or more coupling devices 38 and corresponding tension members 22 in a modular unit 62 can be summarized, the over Connecting means 64, e.g. Dovetail joint, with corresponding modular units 62, 62a, 62b, 62c, 62d could be. The individual switching elements 50, 52 are on Lines 66.68 and 70.72 connected to the contact points 74.76 and 78.80 lead to the corresponding contact points connected modular units 62, 62a, 62b, 62c, 62d cooperate. The lines 66, 68, 70, 72 form one Matrix for controlling the switching elements 50, 52.

Die Figuren 6 bis 8 stellen ein Steuergerät dar, welches horizontal aus modularen Einheiten 62 der Steuervorrichtung aufgebaut ist. In vertikaler Richtung sind einem Zugorgan 82 eine ortsfeste Kupplungsvorrichtung 84 und zwei auf- und abbewegliche Kupplungsvorrichtungen 86,88 zugeordnet, welche Teile der Hubvorrichtung sind. Die Reihe der ortsfesten Kupplungsvorrichtungen 84 bilden somit ein ortsfestes Messer 90 und die Reihe der ersten beweglichen Kupplungsvorrichtungen 86 bilden ein oberes Hubmesser 92 mit dem Hub H1 und die zweiten Kupplungsvorrichtungen 88 ein unteres Hubmesser 94 mit dem Hub H2 der Hubvorrichtung 96. Das obere Hubmesser 92 und das untere Hubmesser 94 der Hubvorrichtung 96 arbeiten im Gegentakt. Das Zugorgan 82 weist neben dem Längsschlitz 98 drei Kupplungsausnehmungen 100,102,104 auf, die jeweils der untersten Stellung der Hubmesser 92,94 zugeordnet sind bzw. dem ortsfesten Messer 90. Weiter enthält das Zugorgan 82 eine vierte Kupplungsausnehmung 106, welche in angehobener Stellung des Zugorganes mit der Kupplungsvorrichtung 84 des ortsfesten Messers 90 zusammenwirkt, wie aus Figur 8 hervorgeht. In der Figur 8 sind die jeweils aktivierten Kupplungsvorrichtungen schraffiert dargestellt.FIGS. 6 to 8 represent a control device which is constructed horizontally from modular units 62 of the control device. In the vertical direction, a pulling element 82 is assigned a stationary coupling device 84 and two up and down moving coupling devices 86, 88, which are parts of the lifting device. The row of stationary coupling devices 84 thus form a stationary knife 90 and the row of first movable coupling devices 86 form an upper lifting knife 92 with the stroke H 1 and the second coupling devices 88 a lower lifting knife 94 with the stroke H 2 of the lifting device 96. The upper one Lifting knife 92 and the lower lifting knife 94 of the lifting device 96 work in push-pull. In addition to the longitudinal slot 98, the traction element 82 has three coupling recesses 100, 102, 104, which are each assigned to the lowest position of the lifting knives 92, 94 or the stationary knife 90. Furthermore, the traction element 82 contains a fourth coupling recess 106, which in the raised position of the traction element with the Coupling device 84 of the fixed knife 90 cooperates, as can be seen from FIG. The respectively activated coupling devices are shown hatched in FIG.

Die Figur 8a zeigt das Zugorgan 82 in der Grundstellung, in der das Zugorgan mittels einer nicht näher dargestellten Rückzugfeder in der Tiefstellung gehalten wird. In der Antriebsphase gemäss Figur 8b ist die Kupplungsvorrichtung 84 des ortsfesten Messers 90 aktiviert und hält das Zugorgan 82 in der Tiefstellung während das obere Hubmesser 92 und das untere Hubmesser 94 sich voneinander weg in die entfernteste Stellung bewegen. Gemäss Figur 8c wird die ortsfeste Kupplungsvorrichtung 84 des ortsfesten Messers 90 gelöst und die Kupplungsvorrichtung 88 des unteren Hubmessers 94 aktiviert, worauf die gegeneinander gerichtete Bewegung der Hubmesser 92,94 beginnt, bis sie die in Figur 8d gezeigte Einstellung erreicht haben. Daraufhin wird die Kupplungsvorrichtung 88 des unteren Hubmessers 94 gelöst und gemäss Figur 8e die ortsfeste Kupplungsvorrichtung 84 des ortsfesten Messers 90 aktivitiert, so dass sich das Zugorgan in der Oberfachstellung befindet. Das obere Hubmesser 92 und das untere Hubmesser 94 bewegen sich voneinander weg in die Figur 9f gezeigte Stellung, in der die ortsfeste Kupplungsvorrichtung 84 des ortsfesten Messers 90 gelöst und das Zugorgan 82 mit der Kupplungsvorrichtung 86 des oberen Hubmessers 92 gekuppelt wird. FIG. 8a shows the pulling element 82 in the basic position, in which the traction element by means of a not shown Retraction spring is held in the low position. In the drive phase 8b is the coupling device 84 of the fixed knife 90 activates and holds the pulling element 82 in the down position while the upper lifting knife 92 and that lower lift knife 94 away from each other in the most distant Move position. According to Figure 8c, the stationary coupling device 84 of the fixed knife 90 solved and the Coupling device 88 of the lower lifting knife 94 activated, whereupon the reciprocating movement of the lifting knife 92.94 begins until it reaches the setting shown in Figure 8d achieved. Thereupon the coupling device 88 of the lower lifting knife 94 and according to FIG. 8e Fixed coupling device 84 of the fixed knife 90 activated so that the pulling element is in the upper compartment position located. The upper lift knife 92 and the lower lift knife 94 move away from each other shown in Figure 9f Position in which the stationary coupling device 84 of the Fixed knife 90 solved and the tension member 82 with the coupling device 86 of the upper stroke knife 92 is coupled.

Daraufhin bewegen sich die Hubmesser 92,94 gegeneinander und das Zugorgan 82 wird wieder in die Unterfach-Stellung gemäss Figur 9 gesenkt. Dort wird die Kupplungsvorrichtung 86 des oberen Hubmessers 92 gelöst und die ortsfeste Kupplung 84 des ortsfesten Messers 90 aktiviert, um das Zugorgan 82 in der Tiefstellung zu halten, worauf die Hubmesser 92,94 wieder voneinander wegbewegt werden können wie Figur 8a zeigt.Thereupon the lifting knives 92, 94 move against each other and that The tension member 82 is again in the lower compartment position according to FIG. 9 lowered. There the coupling device 86 of the upper one Lifting knife 92 released and the fixed coupling 84 of the fixed Knife 90 activated to pull member 82 in the lowered position to hold, whereupon the lifting knives 92.94 again from each other can be moved away as Figure 8a shows.

Durch die horizontale Unterteilung der Messer in modulare Einheiten kann das Steuergerät auch in vertikaler Richtung in einzelne Blöcke unterteilt werden, wobei die elektrischen Leitungen matrizenartig angeordnet sind, dadurch lässt sich, wie aus Figur 5 hervorgeht, die Anzahl der Ein- und Ausgänge für die Steuerelektronik auf eine realisierbare Menge reduzieren. Da die einzelnen modularen Einheiten über elektrische Kontakte miteinander in Verbindung stehen, lassen sich die einzelnen modularen Einheiten und Teilblöcke auch auf einfach Weise voneinander trennen, so dass jede Einheit und jeder Block ohne Demontage der anderen Blöcke oder Einheiten herausgenommen oder ausgewechselt werden kann. Aufgrund der modularen Einheiten ist es möglich, verschiedene Systeme je nach Breite der Textilmaschine und der Anzahl der Kettfäden zusammenzustellen. By dividing the knives horizontally into modular ones The control unit can also move units in the vertical direction individual blocks are divided, the electrical Lines are arranged like a matrix, which means that as can be seen in Figure 5, the number of inputs and outputs for the control electronics to a feasible amount. Since the individual modular units have electrical Contacts are connected to each other, the individual modular units and sub-blocks also on simple Separate ways so that each unit and everyone Block removed without dismantling the other blocks or units or can be replaced. Due to the modular units it is possible to have different systems each according to the width of the textile machine and the number of warp threads put together.
