Description

Die Erfindung betrifft eine Vorrichtung für die Fadenteilung an einer Schärmaschine gemäss dem Oberbegriff von Anspruch 1. Derartige Vorrichtungen dienen dazu, den von einem Spulengatter abgewickelten Fadenverband vor dem Aufwickeln auf die Schärtrommel derart zu öffnen, dass Kreuzschnüre oder andere Teilelemente zum Festlegen der Fadenreihenfolge bzw. zur Bildung von Fadengruppen für den anschliessenden Schlichteprozess eingelegt werden können.The invention relates to a device for thread division on a warping machine according to the preamble of claim 1. Such devices are used by a creel unwound thread bandage before winding onto the Open warping drum in such a way that cross cords or others Sub-elements for specifying the thread order or Formation of thread groups for the subsequent finishing process can be inserted.

Bei der einfachen Fadenkreuzbildung zum Festlegen der Fadenreihenfolge wird die gesamte Fadenschar auf eine Ebene zusammengeführt, wobei mit Hilfe eines Kreuzriets jeweils jeder zweite Faden zur Fachbildung nach unten oder nach oben ausgelenkt wird. Bei der mehrfachen Fadenkreuzbildung für den Schlichteprozess ist die Fachbildung komplizierter, da einzelne Fadengruppen entsprechend den einzelnen Etagen am Spulengatter abgetrennt werden müssen. Die vorliegende Erfindung bezieht sich insbesondere auf eine Vorrichtung für die mehrfache Fadenkreuzbildung zur Bildung der sogenannten Schlichteteilung.With simple crosshairs to set the thread order the entire thread group is brought together on one level, each with the help of a cross reed second thread deflected downwards or upwards to form the subject becomes. With multiple crosshairs for the Mediation process, subject formation is more complicated as individual Thread groups according to the individual floors on Coil creel need to be disconnected. The present invention relates in particular to a device for the multiple crosshairs to form the so-called Sizing division.

Durch die CH-A-370 363 ist eine gattungsmässig vergleichbare Vorrichtung bekannt geworden, bei welcher die Teilstäbe, mit Ausnahme des obersten und des untersten, im Teilstabhalter gemeinsam senkbar und einzeln hebbar gelagert sind, wodurch zum mehrfachen Fadenkreuzschlagen jeweils der Abstand zwischen zwei aufeinanderfolgenden Teilstäben vergrösserbar ist. Zum einzelnen Anheben der Teilstäbe dient ein Klinkenmechanismus, welcher manuell betätigt werden muss. Nach dem Einlegen der letzten Teilschnur sind die Teilstäbe wieder in ihre Ausgangslage rückstellbar, in welcher sie alle untereinander gleiche Abstände aufweisen. Da die Relativlage des obersten und des untersten Teilstabes nie verändert wird, bleibt das Winkelspektrum der Fadenschar insgesamt stets gleich. Innerhalb dieses Spektrums werden jedoch durch verschieben der einzelnen Stangen von oben nach unten die einzelnen Fächer geöffnet. Dies hat den Nachteil, dass jedes Fach sich in einer anderen Relativlage öffnet, was eine automatische Teilschnureinlegung erheblich erschwert. Zum anderen ist die Grösse der Fachöffnung relativ eng begrenzt. Bei der bekannten Vorrichtung werden die Teilschnüre manuell eingelegt.CH-A-370 363 is a genre comparable Appeared device in which the partial rods with Exception of the top and the bottom, in the sub-rod holder can be lowered together and lifted individually, whereby for multiple crosshairs, the distance can be enlarged between two successive bars is. A ratchet mechanism is used to lift the partial rods individually, which has to be operated manually. After this Insert the last part of the cord again their starting position resettable, in which they are all among themselves have the same distances. Since the relative position of the top and bottom part of the bar is never changed, the angular spectrum of the thread family as a whole always remains equal. Within this spectrum, however, are moving through the individual rods from top to bottom the individual Compartments open. This has the disadvantage that each Compartment opens in a different relative position, which is an automatic Partial cord insertion considerably more difficult. On the other hand the size of the compartment opening is relatively narrow. In the known device, the partial cords are inserted manually.

Durch die CH-A-679 867 ist zwar eine Vorrichtung bekannt geworden, bei welcher für die Schlichteteilung die Fachöffnung für alle Fadenetagen an der gleichen Stelle erfolgt. Zu diesem Zweck werden anstelle der Teilstangen mehrere hintereinander angeordnet Schäfte verwendet, welche einzeln vertikal verschiebbar gelagert sind. Jeder Schaft kann dabei eine bestimmte Fadengruppe absenken bzw. anheben. Diese Art der Fadenteilung ist jedoch relativ aufwendig, da jeder einzelne Schaft angetrieben werden muss. Jeder Faden durchläuft eine relativ enge Öse in seiner Schaftlitze und muss mehrere Schaftebenen mit den dort labil gehaltenen Litzen der Nachbarfäden passieren, was den Fadenabrieb begünstigt und zu einer unzureichenden Produktionsgeschwindigkeit führt.A device is known from CH-A-679 867 in which the compartment opening for the size division for all thread levels in the same place. To For this purpose, several are used instead of the partial bars in a row arranged shafts used, which are individually vertical are slidably mounted. Any shaft can do it lower or raise a certain thread group. This kind however, thread division is relatively complex since everyone single shaft must be driven. Every thread goes through a relatively tight eyelet in its shaft strand and must several shaft levels with the strands of the Neighboring threads happen, which favors and increases thread wear insufficient production speed.

Es ist daher eine Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art zu schaffen, welche auf einfachste Weise eine genügend grosse Fachbildung und eine stets gleiche Lage der einzelnen Fächer gewährleistet, so dass das Einlegen der Teilschnüre besser automatisiert werden kann. Diese Aufgabe wird erfindungsgemäss mit einer Vorrichtung gelöst, welche die Merkmale in Anspruch 1 bzw. 7 aufweist.It is therefore an object of the invention to provide a device for to create the kind mentioned above, which in the simplest A sufficiently large subject education and always the same Position of the individual compartments ensures that the insertion the partial cords can be automated better. This According to the invention, the object is achieved with a device which has the features in claims 1 and 7, respectively.

Im Gegensatz zur bekannten Vorrichtung mit verschiebbaren Teilstäben kann die Relativlage des gesamten Teilstabrosts mittels der Hubvorrichtung verändert werden, und zwar so, dass der Teilstabrost aus der ursprünglichen Arbeitslage herausgehoben wird. Eine Verschiebung um das gleiche Mass ist auch nach unten möglich, so dass insgesamt wesentlich grössere Fächer geöffnet werden können, als mit den bekannten Vorrichtungen. Die Sperrvorrichtung ermöglicht die einzelne Freigabe der Teilstäbe, wobei durch obere und untere Leitstangen nach dem Stabrost die Fachgrösse bestimmt werden kann. Diese Leitstangen können auch dazu dienen, die Relativlage der einzelnen Fächer einheitlich zu begrenzen.In contrast to the known device with slidable Partial bars can be the relative position of the entire partial bar grate be changed by means of the lifting device, in such a way that that the partial bar rust from the original working position is lifted out. There is a shift by the same amount also possible downwards, so that overall much larger Compartments can be opened than with the known ones Devices. The locking device enables the individual Release of the partial rods, with upper and lower guide rods the compartment size can be determined after the bar grate can. These guide rods can also serve the relative position limit the individual subjects uniformly.

Eine besonders vorteilhafte Arbeitsweise ergibt sich, wenn in Fadenlaufrichtung nach dem Stabrost je eine obere und eine untere horizontale Leitstange für die obere und untere Lagebegrenzung der Fadenschar angeordnet ist und wenn der unterste Teilstab in der oberen Betriebslage etwa auf der Höhe der oberen Leitstange liegt und wenn oberste Teilstab in der unteren Betriebslage etwa auf der Höhe der unteren Leitstange liegt. Die an sich bekannten Leitstangen sind synchron aufeinander zu bzw. voneinander weg verschiebbar, da sie auch noch dazu benutzt werden, den Fadenverband bei der Betätigung des Kreuzriets auf eine gemeinsame Ebene zusammenzuführen. Durch entsprechende Einstellung dieser Leitstangen kann daher auch die maximale Fachgrösse eingestellt werden.A particularly advantageous way of working results when in Thread running direction after the bar grate one upper and one each lower horizontal guide rod for the upper and lower position limitation the thread sheet is arranged and if the lowest Partial bar in the upper operating position approximately at the level of upper guide rod and if the uppermost part in the lower operating position approximately at the level of the lower guide rod lies. The known guide rods are synchronous with each other Slidable to or from each other, as they are still be used to operate the thread bandage of the cross reed on a common level. By appropriate adjustment of these guide rods can therefore the maximum compartment size can also be set.

Der Anschlag für den Teilstabrost in der unteren Betriebslage wird vorzugsweise unmittelbar durch die Hebevorrichtung gebildet. Es wäre aber ohne weiteres denkbar, den Anschlag unabhängig von der Hebevorrichtung auszubilden, und zwar entweder als fester oder als verstellbarer Anschlag.The stop for the partial bar grate in the lower operating position is preferably carried out directly by the lifting device educated. But it would be easily conceivable, the attack to train independently of the lifting device, namely either as a fixed or adjustable stop.

Die Sperrvorrichtung ist vorteilhaft mit einem Sperrelement versehen, mit dem der jeweils unterste Teilstab in der oberen Betriebslage arretierbar bzw. lösbar ist. Diese Anordnung vereinfacht den mechanischen Aufwand und verbessert die Betriebssicherheit. Es wäre aber auch denkbar, dass jedem einzelnen Teilstab eine eigene Sperre zugeordnet wird, die beispielsweise auch elektromagnetisch funktionieren könnte.The locking device is advantageous with a locking element with which the bottom bar in the top Operating position can be locked or released. This arrangement simplifies the mechanical effort and improves the Operational safety. But it would also be conceivable that everyone individual sub-staff is assigned its own lock, which for example, could also work electromagnetically.

Eine besonders einfache Sperrvorrichtung wird durch eine drehbare Schlitzscheibe mit einem Schlitz gebildet, welche bei Drehung in die Bewegungsebene der Teilstäbe eingreift, wobei der Schlitz jeweils den untersten Teilstab nach unten schiebt, während die darüberliegenden Teilstäbe gesperrt werden. In einer neutralen Lage ausser Eingriff können die Teilstäbe zum Anheben des Teilstabrosts an der Schlitzscheibe vorbeibewegt werden. Anstelle der Schlitzscheibe wären aber auch andere, sequentiell arbeitende Gesperre wie z. B. ein Malteserkreuz-Getriebe oder eine Exzenterscheibe denkbar.A particularly simple locking device is by a rotatable slotted disc formed with a slit which engages in the plane of movement of the partial rods when rotating, with the slot down the bottom part of the bar pushes while the overlying bars are locked will. In a neutral, disengaged position, the Partial bars for lifting the partial bar grate on the slotted disc be moved past. Instead of the slotted disc would be also other, sequentially working ratchet such. B. a Maltese cross gear or an eccentric disc possible.

Die Hubvorrichtung könnte manuell mit einem Hebel oder mit einer Kurbel betätigt werden. Vorzugsweise ist sie jedoch über einen eigenen Antriebsmotor antreibbar, damit die Hubbewegung zusammen mit einem Einlegeautomaten für die Teilschnüre gesteuert werden kann. Gleiches gilt auch für die Sperrvorrichtung, die ebenfalls mit einem eigenen Antriebsmotor versehen wird.The lifting device could be operated manually with a lever or with operated by a crank. However, it is preferred driven by its own drive motor, so that the lifting movement together with an insertion machine for the partial cords can be controlled. The same applies to the Locking device, which also has its own drive motor is provided.

Selbstverständlich wäre es auch denkbar, den ganzen Teilvorgang von unten nach oben abzuwickeln. Zu diesem Zweck könnte der gesamte Stabrost mittels einer Absenkvorrichtung aus einer neutralen Mittellage in eine untere Betriebslage absenkbar sein. Anschliessend wären die Teilstäbe mit einer Hubvorrichtung, z.B. durch einen Paternostertrieb, in eine obere Betriebslage verschiebbar und dort mittels einer Haltevorrichtung fixierbar. Wichtig wäre auch bei dieser Lösung, dass die obere und die untere Betriebslagen so gewählt werden, dass eine grosse Fachbildung mit gleichbleibender Fachlage ermöglicht wird.Of course, it would also be conceivable for the whole sub-process from bottom to top. For this purpose the entire bar grate by means of a lowering device can be lowered from a neutral middle position into a lower operating position be. Then the partial bars would be with a Lifting device, e.g. through a paternoster drive, into a upper operating position slidable and there by means of a holding device fixable. It would also be important with this solution that the upper and lower operating positions are selected so that a large subject education with a constant subject situation is made possible.

Figur 1 zeigt den Gesamtaufbau einer Schäranlage 1 bestehend aus einer Schärmaschine 2 und aus einem Spulengatter 3. Das Spulengatter 3 ist auf verschiedenen Etagen und in verschiedenen Reihen mit Spulen 4 bestückt, von denen in Pfeilrichtung a Fäden 5 abgezogen und auf einer Schärtrommel 9 in Sektionen zu einem Kettwickel 8 aufgewickelt werden. Nach dem Fertigstellen des Kettwickels werden die Fäden auf einen Kettbaum 14 umgebäumt.Figure 1 shows the overall structure of a warping plant 1 consisting from a warping machine 2 and from a creel 3. Das Coil gate 3 is on different floors and in different Rows equipped with coils 4, of which in the direction of the arrow a threads 5 drawn off and on a warping drum 9 in Sections to be wound into a warp 8. After this Finishing the warp wrap the threads on one Warp beam 14 rearranged.

Die einzelnen Fadenetagen sind durch die Teilstäbe 7 in einer Teilstabhalterung 6 voneinander getrennt. Nach den Teilstäben durchlaufen die Fäden 5 auf an sich bekannte Weise noch ein Kreuzriet 10 und ein Schärblatt 11.The individual thread levels are in one by the partial rods 7 Part rod holder 6 separated from each other. After the partial bars pass through the threads 5 in a manner known per se Kreuzriet 10 and a sash 11.

Figur 2 zeigt nun den Bereich der Teilstabhalterung 6 und des Kreuzriets 10 in etwas vergrössertem Massstab. Die Teilstabhalterung besteht im wesentlichen aus seitlichen Führungsschienen 16, in denen der Teilstabrost 19 bestehend aus den Teilstäben 7a bis 7e vertikal verschiebbar ist. Die Teilstäbe liegen dabei auf einem als Greifer ausgebildeten Anschlag 21 einer Hubvorrichtung 22. Die Hubvorrichtung besteht aus einem Elektromotor 23, dessen Getriebe in eine Hubspindel 24 eingreift.Figure 2 now shows the area of the rod holder 6 and Kreuzriets 10 on a somewhat enlarged scale. The partial rod holder consists essentially of side guide rails 16, in which the partial rod grate 19 consisting of the Partial bars 7a to 7e is vertically displaceable. The partial bars lie on a stop 21 designed as a gripper a lifting device 22. The lifting device consists of a Electric motor 23, whose gear engages in a lifting spindle 24.

In Figur 2 steht der Stabrost 19 in einer neutralen Mittelstellung M, in der die Fäden 5 ohne Auslenkung in einem Sektor mit dem Winkel α zu einer Umlenkwalze 20 geführt werden. Je eine obere Leitstange 13 und eine untere Leitstange 17 sind ausserhalb dieses Sektors angeordnet. Das Kreuzriet 10, das hier bei der Schlichteteilung keine Funktion ausübt, steht ebenfalls in einer neutralen Mittellage. Das Schärblatt 11 ist in der Betriebsstellung an die Umlenkwalze 20 angefahren.In Figure 2, the bar grate 19 is in a neutral central position M, in which the threads 5 without deflection in one Sector with the angle α led to a deflecting roller 20 will. An upper guide rod 13 and a lower guide rod 17 are located outside this sector. The Kreuzriet 10, which has no function here in the size division exercises, is also in a neutral middle position. The warping blade 11 is in the operating position on the deflection roller 20 approached.

Neben den vertikalen Führungsschienen 16 ist seitlich wenigstens eine Schlitzscheibe 15 (Figur 5) angeordnet, welche um eine Achse parallel zu den Teilstäben drehbar ist. Die Schlitzscheibe hat einen radial gegen das Zentrum verlaufenden Schlitz 25 und einen geraden Abschnitt 26. Die Schlitzscheibe ist dabei derart angeordnet, dass sie in der in Figur 2 dargestellten Ruhelage mit ihrem geraden Abschnitt 26 ein Verschieben des Stabrosts 19 in den Führungsschienen 16 erlaubt. Dagegen greift sie beim Ausdrehen in die Bewegungsebene des Stabrosts 19. Um ein Verkanten der Teilstäbe in den Führungsschienen 16 zu verhindern, ist vorzugsweise auf jeder Seite der Teilstäbe je eine Schlitzscheibe angeordnet.In addition to the vertical guide rails 16 is at least laterally a slotted disc 15 (Figure 5) arranged around an axis can be rotated parallel to the partial bars. The Slotted disc has a radially running towards the center Slot 25 and a straight section 26. The slot washer is arranged in such a way that in the figure 2 shown rest position with its straight section 26 Moving the bar grate 19 in the guide rails 16 allowed. On the other hand, it reaches into the plane of movement when it is turned out of the rod grate 19. In order to tilt the partial rods in the Preventing guide rails 16 is preferably on everyone One slotted disc is arranged on each side of the partial rods.

Für die Fachbildung zum Einlegen der Teilschnüre 12 werden gemäss Figur 3 die Leitstangen 13 und 17 etwas zusammengefahren, so dass die Fadenschar auf einen etwas kleineren Sektor β begrenzt wird. Gleichzeitig wird das Schärblatt 11 in Richtung Spulengatter zurückgenommen, da die Teilschnüre ersichtlicherweise hinter dem Schärblatt eingelegt werden müssen. Mit Hilfe der Hubvorrichtung 22 wird sodann der ganze Stabrost 19 soweit angehoben, bis der unterste Teilstab 7e etwa auf der gleichen Höhe liegt, wie die obere Leitstange 13. Dabei werden ersichtlicherweise zunächst alle Fäden, bis auf die der untersten Fadenetage, an den einzelnen Leitstangen nach unten umgelenkt.For the specialist training for inserting the partial cords 12 3, the guide rods 13 and 17 are slightly moved together, so that the coulter is on a slightly smaller sector β is limited. At the same time the warping blade 11 in Withdrawn towards the creel because of the partial cords evidently be inserted behind the warping blade have to. With the help of the lifting device 22, the whole Bar grate 19 raised until the bottom part bar 7e is about the same height as the upper guide rod 13. Obviously, all threads are shown until on the lowest thread level, on the individual guide rods deflected downwards.

Beim Erreichen dieser oberen Betriebslage O wird die Schlitzscheibe 15 eingeschwenkt, so dass der Stabrost dort festgehalten wird. Der Anschlag 21 kann nun wieder abgesenkt werden bis zu einer Position, in der er eine untere Betriebslage U definiert. Daraufhin oszilliert die Schlitzscheibe 15 vor und zurück, wobei jedesmal ein Teilstab vom Schlitz 25 erfasst und soweit nach unten geführt wird, bis er durch Schwerkraft in den Führungsschienen 16 nach unten fällt. Gleichzeitig hält die Schlitzscheibe die darüberliegenden Teilstäbe zurück.When this upper operating position O is reached, the slotted disc 15 swung in, so that the bar grate is held there becomes. The stop 21 can now be lowered again to a position in which it has a lower operating position U Are defined. Thereupon the slotted disc 15 oscillates before and back, each time a partial rod from the slot 25 is captured and so far down until it is gravity falls down in the guide rails 16. At the same time the slotted disc holds back the partial bars above.

In Figur 3 ist der untere Teilstab 7e bereits in die untere Betriebslage U gefallen. Der nächste Teilstab 7d wird von der Schlitzscheibe gerade erfasst und nach unten geführt, wobei im Fadenfach 18 eine Teilschnur 12b eingelegt ist. Eine erste Teilschnur 12a wurde bereits in der vorhergehenden Sequenz eingelegt. Zwischen den einzelnen Sequenzen muss jeweils auch der Fadenverband in Pfeilrichtung b eine Nachspannbewegung ausführen. Diese Nachspannbewegung fördert die an den Leitstangen 13 und 17 gebildete Fachöffnung trotz eventueller Faserverhakungen sicher zum Teilfachbereich 18 und sie bringt die Teilschnüre 12 auf eine arbeitsgerechte Abstandslage in der Kette 8.In Figure 3, the lower part of the rod 7e is already in the lower Operating situation U fallen. The next sub-bar 7d is from the Slotted disc just grasped and led down, whereby a partial cord 12b is inserted in the thread compartment 18. A first one Partial cord 12a was already in the previous sequence inserted. Between the individual sequences must also the thread assembly in the direction of the arrow b a tensioning movement To run. This tensioning movement promotes the on the guide rods 13 and 17 formed opening despite possible Fiber entanglement safely to sub-area 18 and it brings the partial cords 12 to a work-related distance position in the chain 8.

Aus Figur 4 ist ersichtlich, dass die untere Betriebslage U so festgelegt ist, dass der oberste Teilstab 7a etwa auf der gleichen Höhe liegt wie die untere Leitstange 17. Zwischen der ersten und der letzten Sequenz werden die das Fach begrenzenden Fäden jedoch immer über die Leitstangen 13 und 17 umgelenkt, so dass das Fadenfach immer die gleiche Relativlage einnimmt. Nach dem Einlegen der letzten Teilschnur wird die Schlitzscheibe 15 wieder in die Ruhelage zurückgedreht, so dass der Stabrost 19 mittels der Hubvorrichtung wieder in die Mittelstellung M zurückgefahren werden kann. In dieser Mittelstellung durchlaufen die Fäden 5 den Stabrost umschlingungsfrei mit Produktionsgeschwindigkeit.It can be seen from FIG. 4 that the lower operating position U is set so that the uppermost part bar 7a approximately on the same height as the lower guide rod 17. Between The first and last sequences become the ones that limit the subject However, threads always on the guide rods 13 and 17 deflected so that the thread compartment always the same relative position occupies. After inserting the last part of the cord the slotted disc 15 is turned back to the rest position, so that the bar grate 19 in again by means of the lifting device the middle position M can be retracted. In this In the middle position, the threads 5 pass through the rod grating without being looped with production speed.

Figur 5 zeigt die seitliche Anordnung der Getriebe für den Antrieb der Hubvorrichtung und der Schlitzscheiben.
