Description
Die Erfindung betrifft eine Saugdüse für eine Arbeitsstelle einer Kreuzspulen herstellenden Textilmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a suction nozzle for a workstation of a cross-wound textile machine according to the preamble of
Im Zusammenhang mit dem Betrieb von Kreuzspulen herstellenden Textilmaschinen, insbesondere von Kreuzspulautomaten, ist es üblich, im Falle einer Spulunterbrechung, zum Beispiel bei einem Fadenbruch, bei einem kontrollierten Reinigerschnitt oder bei einem Vorlagespulenwechsel über einen Spulstellenrechner der betreffenden Spulstelle eine arbeitsstelleneigene Fadenverbindungsautomatik zu aktivieren.In connection with the operation of cheese-producing textile machines, in particular automatic packages, it is customary in the case of a winding interruption, for example in a thread break, in a controlled cleaner cut or on a supply bobbin change over a winding station of the winding unit in question to activate a working-own threading automatic.
Das heißt, der Spulstellenrechner sorgt dafür, dass, wie beispielsweise in der
Die Saugdüse versucht dabei, mit ihrer Mündung das Fadenende des Oberfadens von der Oberfläche der als Kreuzspule ausgebildeten Auflaufspule aufzunehmen.The suction nozzle attempts to record with its mouth the yarn end of the upper thread from the surface of the package designed as a cross-wound bobbin.
Nach dem Erfassen des Oberfadenendes schwenkt die Saugdüse in ihre Ausgangslage, in der die Mündung der Saugdüse unterhalb einer Fadenspleirsvorrichtung positioniert ist, zurück.After detecting the upper thread end, the suction nozzle pivots back to its original position, in which the mouth of the suction nozzle is positioned below a yarn ply device.
Der sich zwischen der Kreuzspule und der Saugdüse erstreckende Fadenstrang wird dabei in einen oberhalb der Fadenverbindungsvorrichtung angeordneten elektronischen Reiniger, eine in diesem Bereich positionierte Klemm- und Schneideinrichtung sowie, durch entsprechende Leitkonturen von Fadenleitblechen und Fadenleitbügeln geführt, in die Schere einer unterhalb der Spleißvorrichtung befindlichen Schneideinrichtung eingezogen.The yarn strand extending between the cross-wound bobbin and the suction nozzle is placed in an electronic cleaner arranged above the yarn joining device, a clamping and cutting device positioned in this region and, by means of corresponding guide contours of Thread guide plates and Fadenleitbügeln out, fed into the shears of a cutting device located below the splicer.
Nahezu gleichzeitig mit der Saugdüse schwenkt ein in einer unteren Ausgangslage positioniertes Greiferrohr in eine obere Arbeitsstellung und bringt dabei einen bis dahin beispielsweise in einem Fadenspanner gehaltenen, von der Vorlagespule abgezogenen Unterfaden mit.Almost at the same time as the suction nozzle, a gripper tube positioned in a lower starting position pivots into an upper working position, bringing with it a lower thread that has been held until then, for example in a thread tensioner, drawn from the supply spool.
Beim Einschwenken des Greiferrohres in seine obere Arbeitsstellung gleitet der Unterfaden, der ebenfalls an entsprechenden Fadenleitkonturen geführt ist, in eine geöffnete Fadenklemme sowie eine geöffnete Schneideinrichtung. Unter- und Oberfaden werden anschließend auf die richtige Länge abgeschnitten, in so genannten Auflöseröhrchen vorbereitet und in der Fadenspleißeinrichtung miteinander verbunden.When swinging the gripper tube in its upper working position of the lower thread, which is also performed on corresponding Fadenleitkonturen slides in an open thread clamp and an open cutter. The lower and upper threads are then cut to the correct length, prepared in so-called Auflöseröhrchen and connected together in the Fadensleiißeinrichtung.
Das bedeutet, an den Arbeitsstellen eines Kreuzspulautomaten werden, um, zum Beispiel nach einem Fadenbruch, den Betrieb automatisch fortführen zu können, stets sowohl ein von der Kreuzspule zurückgeholter Oberfaden als auch ein von der Vorlagespule kommender Unterfaden benötigt.This means that at the workstations of a cheese winder, in order, for example, to be able to continue the operation automatically after a yarn breakage, both an upper thread taken back from the cheese and a bobbin thread coming from the supply bobbin are always required.
Die vorbeschriebenen Fadenverbindungsautomatiken haben sich in der Praxis bewährt und sind in der Textilindustrie seit langer Zeit in großer Stückzahl im Einsatz.The above-described automatic yarn binding devices have proven themselves in practice and have been used in the textile industry in large quantities for a long time.
Bei diesen bekannten Einrichtungen treten allerdings gelegentlich Schwierigkeiten bei der Aufnahme des Oberfadenendes von der Oberfläche der Auflaufspule auf.In these known devices, however, occasionally encounter difficulties in receiving the upper thread end of the surface of the package.
Diese Schwierigkeiten ergeben sich insbesondere dann, wenn das auf die Kreuzspule aufgelaufene Fadenende weit am Rande der Kreuzspule aufgelaufen ist und dabei eventuell auch noch relativ stark eingewalkt wurde.These difficulties arise in particular when the accumulated on the cross-wound yarn end has accumulated far at the edge of the cheese and possibly also was relatively severally infiltrated.
In solchen Fällen ist die Saugkraft der bekannten Saugdüsen, besonders in den Randbereichen ihrer relativ breiten Mündung, oftmals nicht ausreichend, um das Fadenende des Oberfadens sicher von der Oberfläche der Auflaufspule aufzunehmen.In such cases, the suction force of the known suction nozzles, especially in the edge regions of their relatively wide mouth, is often insufficient to securely receive the yarn end of the upper thread from the surface of the package.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Saugdüse zu entwickeln, die so ausgebildet ist, dass ein auf die Kreuzspule aufgelaufenes Fadenende eines Oberfadens sicherer gehandhabt werden kann.Based on the aforementioned prior art, the present invention seeks to develop a suction nozzle, which is designed so that an accumulated on the cross-wound yarn end of an upper thread can be handled safely.
Das heißt, dass ein Fadenende auch dann noch zuverlässig aufgenommen werden kann, wenn das Fadenende im Randbereich der Auflaufspule aufgelaufen und eventuell eingewalkt ist.This means that a thread end can still be reliably picked up even if the thread end has accumulated in the edge region of the package and possibly eingealkt.
Diese Aufgabe wird erfindungsgemäß durch eine Saugdüse gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved by a suction nozzle, as described in
Vorteilhafte Ausgestaltungen der erfindungsgemäßen Saugdüse sind Gegenstand der Unteransprüche.Advantageous embodiments of the suction nozzle according to the invention are the subject of the dependent claims.
Die erfindungsgemäße Saugdüse hat den Vorteil, dass der innerhalb der Saugdüse wirksame Saugluftstrom, insbesondere auch im Bereich der Eingangsöffnung, verstärkt auf die seitlichen Randbereiche der Eingangsöffnung der Saugdüse konzentriert und damit in den Problemzonen der Auflaufspule intensiver wirksam wird.The suction nozzle according to the invention has the advantage that the effective suction air flow within the suction nozzle, especially in the region of the inlet opening, concentrated concentrated on the lateral edge regions of the inlet opening of the suction nozzle and thus becomes more effective in the problem areas of the package.
Das heißt, durch die Profilierung wird dieser Abschnitt der Saugdüse in zwei seitliche Querschnittsbereiche und einen dazwischen angeordneten, mittleren Querschnittsbereich aufgeteilt, wobei der Luftdurchsatz im Bereich der seitlichen Querschnittsbereiche, nicht zuletzt aufgrund ihrer in weiten Bereichen größeren Höhe, über dem Luftdurchsatz des mittleren Querschnittsbereiches liegt.That is, by the profiling, this section of the suction nozzle is divided into two lateral cross-sectional areas and an intermediate cross-sectional area arranged therebetween, the air flow in the region of the lateral cross-sectional areas, not least because of their far greater height, above the air flow rate of the central cross-sectional area ,
Wie im Anspruch 2 dargelegt, ist die Profilierung vorzugsweise Bestandteil eines Saugdüsendeckels, der, beispielsweise über Schraubenbolzen, mit einem Saugdüsenfuß verbunden ist.As set forth in
Eine solche Ausführungsform lässt sich durch Spritz- oder Druckgussteile kostengünstig realisieren.Such an embodiment can be realized inexpensively by injection or pressure casting.
Das heißt, diese in entsprechenden Urformwerkzeugen gefertigten Bauteile können mittels z. B. Schraubenbolzen oder dgl. schnell und problemlos zu einer erfindungsgemäßen Saugdüse zusammengefügt werden.That is, these manufactured in the corresponding original tools components can be replaced by z. B. bolts or the like. Can be assembled quickly and easily to a suction nozzle according to the invention.
Entsprechende Versuche haben ergeben, dass eine besonders vorteilhafte Ausführungsform der Saugdüse gegeben ist, wenn, wie im Anspruch 3 dargelegt, die Höhe der seitlichen Querschnittsbereiche und die Höhe des mittleren Querschnittsbereiches mit wachsendem Abstand zum Eingangsbereich der Saugdüse größer wird.Corresponding experiments have shown that a particularly advantageous embodiment of the suction nozzle is given if, as set forth in
Auf diese Weise erhält man im Bereich der Eingangsöffnung insgesamt eine relativ starke Saugwirkung, durch die das Fadenende aufgenommen wird, während der in die Saugdüse eingesaugte Faden innerhalb der Saugdüse relativ schonend behandelt wird.In this way, one obtains a relatively strong suction in the region of the inlet opening, through which the thread end is received, while the suctioned into the suction nozzle thread is treated relatively gently within the suction nozzle.
Gemäß Anspruch 4 weist die Saugdüse in ihrem endseitigen Bereich Luftführungsflächen auf, die vorteilhafterweise einstückig an den Saugdüsendeckel angeformt sind.According to
Durch solche Luftführungsflächen lässt sich auf einfache Weise eine definierte Saugluftströmung in der Saugdüse erzielen.By such air guide surfaces can be achieved in a simple manner, a defined suction air flow in the suction nozzle.
Das heißt, Luftverwirbelungen, die auch den aufgenommenen Faden negativ beeinflussen würden, werden weitestgehend vermieden.That is, air turbulence, which would also adversely affect the recorded thread, are largely avoided.
Durch die im Anspruch 5 beschriebene Ausbildung der Saugdüse, bei der der Saugdüsenkopf im Bereich der Eingangöffnung mit einer Kammleiste ausgestattet ist, wird die Güte der Arbeitsleistung der Saugdüse bei der Fadenendaufnahme weiter verbessert.Due to the design of the suction nozzle described in
Die Kammleiste sorgt beispielsweise beim Zurückschwenken der Saugdüse dafür, dass zum Beispiel Schlaufen, die eventuell im aufgenommenen Faden vorhanden sind, ausgekämmt werden, so dass beim anschließenden Fadenverbindungsvorgang stets nur ein Einzelfaden vorliegt.The comb strip, for example, when pivoting back the suction nozzle ensures that, for example, loops, which may be present in the recorded thread, are combed out, so that there is always only a single thread during the subsequent yarn joining process.
