Definitions
- the invention relates to a device for introducing weft threads in an air jet loom with at least one set of successively connected main nozzles, each associated with a control valve whose settings determine the strength of a pulse transmission to the weft, the control valves by means of a control and adjustable are.
- a set of main nozzles connected in series is used to enter a weft thread.
- two main nozzles are connected in series, one of which is stationary and the other on a batten.
- the invention has for its object to provide a device of the type mentioned, in which the vote of the shares of the main nozzles on the impulse transmission is straightforward.
- the control and regulating device when setting a weaving machine to a new fabric, only a total value for the strength of the momentum transfer has to be set.
- the control and regulating device then automatically takes over the setting of the individual control valves in a predetermined ratio to each other.
- This automatic assignment of the settings of the control valves with each other is also retained when the weft insertion is regulated, for example, for the entry of weft threads of filament yarn.
- the momentum transfer becomes the manipulated variable, which varies depending on the diameter of a weft coil.
- the regulation changes the amount of compressed air and / or the pressure of the compressed air as a manipulated variable.
- the control and regulating device automatically ensures that the ratio of the settings of the control valves of the main nozzles of a set is maintained in a suitable manner, according to predetermined criteria.
- Fig. 1 is a loom 10 indicated by a loom on which a reed 11 and relay nozzles 12 are arranged.
- a main nozzle 13 is arranged on the entry side, which forms, with an upstream main nozzle 14, a set of main nozzles which serve to introduce a weft thread 15.
- the main nozzle 14 is fixedly mounted on the frame of the loom.
- a weft thread 15 is measured in a known manner by means of a Vorspulaus 16 and blown by the main nozzles 13, 14 in a formed of warp threads shed. Within the shed, the weft is drawn from the relay nozzles 12, i. taken from the air streams blown out of these, and further transported to the opposite side of the loom. The arrival of the weft thread 15 on the side opposite the entry side is detected by means of a weft detector 30 and reported as a pulse signal a control and regulating device 17.
- the relay nozzles 12 are connected to a compressed air supply device, which is not shown in detail.
- the main nozzles 13, 14 are also connected to a source of compressed air or a device for supplying compressed air.
- this contains a compressed-air source 18, which supplies compressed air to a tank 20 via a pressure-regulating valve 19.
- the main nozzles 13, 14 are each connected via a control valve 21, 22 and a switching valve 23, 24 to the tank 20.
- the control device 17 determines the switching times of the switching valves 23, 24 and the settings of the control valves 21, 22.
- the main nozzles 13, 14 are connected via reducing valves 25, 26 to the tank. In the line between the reducing valves 25, 26 and the main nozzles 13, 14, a check valve 27, 28 is provided in each case.
- the control valves 21, 22 are preferably flow control valves, with which the amount of compressed air, which flows to the main nozzles 13, 14, when the switching valves 23, 24 are opened. In the shooting pauses, i. when the switching valves 23, 24 are closed, compressed air flows from the tank 20 via the reducing valves 25, 26 to the main nozzles 13, 14. Thus, a compressed air flow is maintained in the main nozzles 13, 14, which keeps the weft thread 15 stretched.
- the control valves 21, 22 pressure control valves.
- the control and regulating device 17 further receives information about the instantaneous angular position of the main shaft of the loom. In the embodiment, this is done for example via an angle detector 31, which is associated with the shaft of the sley 10.
- control and regulating device 17 is associated with an input unit 29, with the example, the target value for the angle of arrival of the main shaft can be entered, that is, the angle detected by the angle detector 31 angular position at which the weft thread 15 to reach the weft detector 30.
- the operator can also adjust the impulse transmission to the weft thread 15 exerted by the set of main nozzles 13, 14.
- Fig. 2 is shown with the X-axis, is provided for the pulse transmission, a setting range of about 25% to 100%.
- the controller 17 automatically assigns to the selected value of the pulse transmission settings of the control valves 21, 22 of the main nozzles 13, 14, ie, for example, the opening cross sections of these control valves 21, 22.
- the settings of Control valves 21, 22 determines what proportion of each main nozzle 13, 14 at the entire momentum transfer to the weft thread 15 has.
- the control valve 21 of the main nozzle 13 is set according to the straight line 40 proportional to the selected pulse transmission, so that at 100% pulse transmission, the control valve 21 is fully open, ie, the opening cross section is 100%.
- the opening cross section at 25% impulse transmission is 25%, etc.
- the control and regulating device 17 automatically assigns an adjustment of the control valve 22 of the main nozzle 14 to the value of the selected impulse transmission. This assignment is with the curve 41 in FIG Fig. 2 shown.
- the control valve 22 opens less than the control valve 21, ie the curve 41 has a lower slope than the curve 40.
- the adjustment of the control valve 21 of the main nozzle 13 for adjusting the value of the pulse transmission takes place so that, for example, already at 75% pulse transmission a setting of 83% of the opening cross-section of the control valve 21 of the main nozzle 13 is achieved and at a momentum transfer of 90% already 100% opening cross section.
- a setting of 83% of the opening cross-section of the control valve 21 of the main nozzle 13 is achieved and at a momentum transfer of 90% already 100% opening cross section.
- an increase thus takes place essentially only by an increase in the momentum transfer by means of the main nozzle 14 whose control valve 22 is still changed in this area, for example, to a larger opening cross section.
- the setting of the impulse transmission is done by means of an "imaginary" main nozzle.
- the Weber sets a value for the momentum transfer, for example, 80%, in which case the control and regulating device 17 automatically adjusts the control valves 21, 22 to suitable values, for example so that the opening cross section of the control valve 21 to 90% and the opening cross section of the control valve 22 of the main nozzle 14 is set to 70%.
- control valves 21, 22 are expediently equipped with stepper motors, which provide an exact adjustment of the opening cross-sections of the Control valves 21, 22 allow.
- the control and regulating device 17 drives these stepper motors with pulses.
- Such control valves are for example from the EP 879 307 B1 and the EP 1 086 265 B1 known.
- filament yarn weft yarns 15 are relatively air-unfriendly when they are from outer layers of a weft yarn bobbin. They then become more and more air-friendly, if they come from further inside layers of this weft coil. Therefore, at the beginning of the execution of a weft bobbin, a stronger momentum transfer is needed, i. a relatively high pressure and / or a relatively high amount per unit time of compressed air, which are then reduced more and more, the farther this weft coil is processed.
- This reduction of the momentum transfer can be done by means of a control that detects the arrival of the weft thread on the main nozzles 13, 14 opposite side by means of the weft detector 30 and the control and regulating device 17 reports.
- the control and regulating device 17 additionally receives information about the instantaneous angle of rotation of the main shaft of the loom, for example by means of the angle detector 31 of the shaft of the sley 10. By means of these signals is detected whether a weft thread has arrived at the correct angular position of the main shaft of the loom. In the case of deviations, regulation takes place via the setting of the impulse transmission, i. the adjustment of the control valves 21, 22, in such a way that a constant angle of arrival is obtained.
- the control and regulating device 17 automatically adjusts the ratio of the settings of the control valves 21, 22 in accordance with the changed momentum transfer.
- These main nozzles are each control valves 21, 22, 47 assigned, which are actuated by the control and regulating device 17.
- the control valves 21, 22, 47 are preceded by a common switching valve 49 which connects these control valves 21, 22, 47 with the tank 20.
- the common switching valve 49 is actuated by the control and regulating device 17.
- the controller 17 determines the ratio in which the control valves 21, 22, 47 are adjusted to each other, ie the proportion of the main nozzles 13, 48, 14 on the entire pulse transmission.
- the weaver selects a momentum transfer of an "imaginary" main nozzle, which then automatically divides the control and regulating device by means of the setting of the control valves 21, 47, 22 on the main nozzles 13, 48, 14, without the weaver in normal operation of the loom some of it noted.
- the number of main nozzles is basically arbitrary. If more than two main nozzles are provided, according to the invention at least two main nozzles should each be assigned a control valve which can be adjusted by the control and regulating device 17.
- the operator of the weaving machine determines how the control and regulating device should work.
- the weaver can also decide that during weaving the control and regulating device, for example, a setting of the control valves 21, 22 according to Fig. 2 has made to a setting according to Fig. 3 passes.
- a setting of the control valves 21, 22 according to Fig. 2 has made to a setting according to Fig. 3 passes.
- the control valves are adjusted Fig. 2 to a setting according to Fig. 3 is passed.
- the control valve 21 is no longer at the value of 75%, but to the value of 83% according to the curve 42 after Fig. 3 set.
- the curves 41 are the same. However, this is only an example, since the curves can also be formed substantially different. In particular, it is also possible to provide over the entire adjustment range of the pulse transmission that the ratio of the settings between the control valves 21, 22 of the main nozzles 13, 14 remains constant or that over the entire adjustment range, a constant difference is maintained.

Description
Die Erfindung betrifft eine Vorrichtung zum Eintragen von Schussfäden bei einer Luftdüsenwebmaschine mit wenigstens einem Satz von hinter einander geschalteten Hauptdüsen, denen jeweils ein Regelventil zugeordnet ist, deren Einstellungen die Stärke einer Impulsübertragung auf den Schussfaden bestimmen, wobei die Regelventile mittels einer Steuer- und Regeleinrichtung einstellbar sind.The invention relates to a device for introducing weft threads in an air jet loom with at least one set of successively connected main nozzles, each associated with a control valve whose settings determine the strength of a pulse transmission to the weft, the control valves by means of a control and adjustable are.
Ein Satz von hintereinander geschalteten Hauptdüsen dient jeweils zum Eintragen eines Schussfadens. In den meisten Fällen werden zwei Hauptdüsen hintereinander geschaltet, von welchen eine stationär und die andere auf einer Weblade angeordnet ist.A set of main nozzles connected in series is used to enter a weft thread. In most cases, two main nozzles are connected in series, one of which is stationary and the other on a batten.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der die Abstimmung der Anteile der Hauptdüsen an der Impulsübertragung unproblematisch ist.The invention has for its object to provide a device of the type mentioned, in which the vote of the shares of the main nozzles on the impulse transmission is straightforward.
Diese Aufgabe wird durch die Merkmale aus Pätentanspruch 1 gelöst.This object is achieved by the features of Pätentanspruch 1.
Aufgrund der erfindungsgemäßen Ausbildung muss bei einem Einstellen einer Webmaschine auf ein neues Gewebe nur ein Gesamtwert für die Stärke der Impulsübertragung eingestellt werden. Die Steuer- und Regeleinrichtung übernimmt dann selbsttätig die Einstellung der einzelnen Regelventile in einem vorbestimmten Verhältnis zueinander. Diese automatische Zuordnung der Einstellungen der Regelventile untereinander bleibt auch erhalten, wenn der Schusseintrag geregelt wird, beisplelsweise für das Eintragen von Schussfäden aus Filamentgarn. In diesem Fall ist es zweckmäßig, beispielsweise eine Regelung auf einen konstanten Ankunftswinkel durchzuführen, d.h. auf einen Winkel der Hauptwelle der Webmaschine, bei welcher ein Schussfaden auf der gegenüberliegenden Seite ankommt. Bei dieser Regelung wird die Impulsübertragung die Stellgröße, die sich abhängig mit dem Durchmesser einer Schussfadenspule ändert. Bei Schussfäden aus Filamentgarn tritt häufig der Fall ein, dass Schussfäden von den äußeren Lagen der Spule mit einer größeren Menge an Druckluft und/oder mit Druckluft mit höherem Druck eingetragen werden müssen als gegen Ende der aufgebrauchten Spule. Um einen konstanten Ankunftswinkel einzuhalten, wird von der Regelung die Menge an Druckluft und/oder der Druck der Druckluft als Stellgröße verändert. Bei dieser Veränderung der Stellgröße sorgt die Steuer- und Regeleinrichtung selbsttätig dafür, dass das Verhältnis der Einstellungen der Regelventile der Hauptdüsen eines Satzes in geeigneter Weise, nach vorgegebenen Kriterien eingehalten wird.Because of the design according to the invention, when setting a weaving machine to a new fabric, only a total value for the strength of the momentum transfer has to be set. The control and regulating device then automatically takes over the setting of the individual control valves in a predetermined ratio to each other. This automatic assignment of the settings of the control valves with each other is also retained when the weft insertion is regulated, for example, for the entry of weft threads of filament yarn. In this Case, it is expedient, for example, to carry out a control to a constant angle of arrival, ie to an angle of the main shaft of the loom, in which a weft yarn arrives on the opposite side. In this scheme, the momentum transfer becomes the manipulated variable, which varies depending on the diameter of a weft coil. When filament yarn weft threads often occurs that weft threads must be entered from the outer layers of the coil with a larger amount of compressed air and / or compressed air at a higher pressure than towards the end of the spent coil. In order to maintain a constant angle of arrival, the regulation changes the amount of compressed air and / or the pressure of the compressed air as a manipulated variable. In this change in the manipulated variable, the control and regulating device automatically ensures that the ratio of the settings of the control valves of the main nozzles of a set is maintained in a suitable manner, according to predetermined criteria.

In
Ein Schussfaden 15 wird in bekannter Weise mittels eines Vorspulgerätes 16 abgemessen und von den Hauptdüsen 13, 14 in ein aus Kettfäden gebildetes Webfach eingeblasen. Innerhalb des Webfaches wird der Schussfaden von den Stafettendüsen 12, d.h. von den von diesen ausgeblasenen Luftströmen, übernommen und zur gegenüberliegenden Seite der Webmaschine weiter transportiert. Die Ankunft des Schussfadens 15 auf der der Eintragsseite gegenüberliegenden Seite wird mittels eines Schussfadenwächters 30 detektiert und als Impulssignal eine Steuer- und Regeleinrichtung 17 gemeldet. Die Stafettendüsen 12 sind an einer Druckluftversorgungseinrichtung angeschlossen, die nicht näher dargestellt ist.A
Die Hauptdüsen 13, 14 sind ebenfalls an eine Druckluftquelle oder eine Einrichtung zur Versorgung mit Druckluft angeschlossen. Diese enthält bei dem Ausführungsbeispiel eine Druckluftquelle 18, die über ein Druckregulierventil 19 Druckluft einem Tank 20 zuführt. Die Hauptdüsen 13, 14 sind jeweils über ein Regelventil 21, 22 und ein Schaltventil 23, 24 an den Tank 20 angeschlossen. Die Steuer- und Regeleinrichtung 17 bestimmt die Schaltzeitpunkte der Schaltventile 23, 24 und die Einstellungen der Regelventile 21, 22. Zusätzlich sind die Hauptdüsen 13, 14 über Reduzierventile 25, 26 an den Tank angeschlossen. In der Leitung zwischen den Reduzierventilen 25, 26 und den Hauptdüsen 13, 14 ist jeweils ein Rückschlagventil 27, 28 vorgesehen.The
Die Regelventile 21, 22 sind vorzugsweise Mengenregelventile, mit denen die Druckluftmenge geregelt werden kann, die zu den Hauptdüsen 13, 14 strömt, wenn die Schaltventile 23, 24 geöffnet sind. In den Schusspausen, d.h. wenn die Schaltventile 23, 24 geschlossen sind, strömt Druckluft aus dem Tank 20 über die Reduzierventile 25, 26 zu den Hauptdüsen 13, 14. Damit wird in den Hauptdüsen 13, 14 eine Druckluftströmung aufrechterhalten, die den Schussfaden 15 gespannt hält. Bei einer abgewandelten Ausführungsform sind die Regelventile 21, 22 Druckregelventile.The

Weiter ist der Steuer- und Regeleinrichtung 17 eine Eingabeeinheit 29 zugeordnet, mit der beispielsweise der Sollwert für den Ankunftswinkel der Hauptwelle eingegeben werden kann, d.h. die von dem Winkeldetektor 31 erfasste Winkelposition, bei welcher der Schussfaden 15 den Schussfadenwächter 30 erreichen soll. Mittels der Eingabeeinheit 29 kann die Bedienungsperson darüber hinaus auch die von dem Satz von Hauptdüsen 13, 14 ausgeübte Impulsübertragung auf den Schussfaden 15 einstellen. Wie in

Es kann vorgesehen werden, dass in der Steuer- und Regeleinrichtung 17 mehrere. Verläufe für die Kurven 40, 41 abgelegt werden, die eine Bedienungsperson entsprechend vorbekannten Kriterien auswählen kann, um den Schusseintrag zu optimieren. Alternativ kann aber auch vorgesehen werden, dass die Bedienungsperson den Verlauf der Kurven 40 oder 41 und insbesondere den Verlauf der Kurve 41 selbst konfiguriert und so das Verhältnis bestimmt, in welchem die Steuer- und Regeleinrichtung dann das Verhältnis der Einstellungen der Regelventile 21, 22 der Hauptdüsen 13, 14 zueinander vornimmt.It can be provided that in the control and regulating

Aus dem Vorstehenden wird deutlich, dass die Einstellung der Impulsübertragung mittels einer "imaginären" Hauptdüse erfolgt. Der Weber stellt einen Wert für die Impulsübertragung von beispielsweise 80% ein, wobei dann die Steuer- und Regeleinrichtung 17 selbsttätig die Regelventile 21, 22 auf geeignete Werte einstellt, beispielsweise so, dass der Öffnungsquerschnitt des Regelventils 21 auf 90% und der Öffnungsquerschnitt des Regelventils 22 der Hauptdüse 14 auf 70% eingestellt wird.From the above it is clear that the setting of the impulse transmission is done by means of an "imaginary" main nozzle. The Weber sets a value for the momentum transfer, for example, 80%, in which case the control and regulating

Wenn Schussfäden aus Filamentgarn verwoben werden, so ist es möglich, den Schusseintrag zu regeln. Es hat sich gezeigt, dass Schussfäden 15 aus Filamentgarn relativ luftunfreundlich sind, wenn sie von äußeren Lagen einer Schussfadenspule stammen. Sie werden dann mehr und mehr luftfreundlich, wenn sie von weiter innen liegenden Lagen dieser Schussfadenspule stammen. Zu Beginn des Abarbeitens einer Schussfadenspule wird deshalb eine stärkere Impulsübertragung benötigt, d.h. ein relativ hoher Druck und/oder eine relativ hohe Menge pro Zeiteinheit an Druckluft, die dann mehr und mehr reduziert werden, je weiter diese Schussfadenspule abgearbeitet wird. Dieses Reduzieren der Impulsübertragung kann mittels einer Regelung erfolgen, die mittels des Schussfadenwächters 30 die Ankunft des Schussfadens auf der den Hauptdüsen 13, 14 gegenüber liegenden Seite erfasst und der Steuer- und Regeleinrichtung 17 meldet. Die Steuer- und Regeleinrichtung 17 erhält zusätzlich Informationen über den momentanen Drehwinkel der Hauptwelle der Webmaschine, beispielsweise mittels des Winkeldetektors 31 der Welle der Weblade 10. Mittels dieser Signale wird erfasst, ob ein Schussfaden bei der richtigen Winkelposition der Hauptwelle der Webmaschine angekommen ist. Bei Abweichungen erfolgt eine Regelung über die Einstellung der Impulsübertragung, d.h. der Einstellung der Regelventile 21, 22, in der Weise, dass ein konstanter Ankunftswinkel erhalten wird. Die Steuer- und Regeleinrichtung 17 stellt dabei automatisch das Verhältnis der Einstellungen der Regelventile 21, 22 entsprechend der geänderten Impulsübertragung ein.When weft threads of filament yarn are woven, it is possible to control the weft insertion. It has been found that filament
