Definitions
- the invention relates to a method for removing the thread residue from a yarn carrier used on textile machines, on the outer surface of which there are uncoiled thread layers, the yarn carrier being clamped at least at one end in a holder and then the thread carrier held clamped and a at least one knife carrying Knife head are moved relative to each other in such a way that the free end of the at least one knife is moved parallel to a surface line of the thread carrier outer surface for the purpose of severing the thread layers at a short distance from the thread carrier surface, such that after severing the thread layers, the thread carrier and a blowing device with at least one arranged on this and directed obliquely against the thread carrier jacket surface in the direction of the free thread carrier end facing away from the holding mandrel, are moved relative to one another and by means of compressed air emerging at the nozzle, the thread number to be removed est forming, severed thread layers are stripped from the yarn carrier.
- the invention further relates to an apparatus for performing the method.
- the present invention was therefore based on the object of further improving the complete removal of the thread remainder from thread carriers and at the same time achieving a high degree of economy in thread removal and cleaning of the thread carrier.
- a method with the measures according to claim 1 serves to solve this problem.
- the yarn carrier after cutting through the yarn residues on the yarn carrier, the yarn carrier is set in rotation and freed from the thread residues by means of simultaneous blowing (compressed air) and by using a suction nozzle. At the same time, the surface of the yarn carrier is also freed of dust and small foreign bodies.
- the device for performing the method has the features of claim 3.
- the essential parts are a device for clamping a yarn carrier between two holding mandrels, a knife head carrying at least one knife and a blowing device having at least one nozzle, by means of which the thread layers previously separated by the knife are stripped from the yarn carrier by compressed air, whereby this is set in rapid rotation by one of the holding mandrels, a suction device and a device for releasing the yarn carrier from the rotatable holding mandrel.
- the yarn carrier as well as the knife and the blowing device must move relative to one another with the aid of guide means.
- these guide means have a slide which can be oscillated along a slide guide, on which a support with a receiving cone forming the rotatable holding mandrel for holding the sleeve-shaped Thread carrier are arranged on the inner peripheral edge and with a drive for the rotatable receiving cone, as well as a further support with a pressing cone forming the second holding mandrel, the latter being axially movable with the aid of a pressing cylinder in order to be moved away from the package after the thread layers have been severed , so that the severed thread layers can be stripped from the yarn carrier with the help of the blowing nozzle over the then free end of the yarn carrier with rapid rotation of the yarn carrier and can reach an unobstructed suction channel opening in the area of the yarn carrier end.
- the slide guide therefore extends along a straight conveyor line, on which, in series, a loading station with means for automatically clamping a yarn carrier between the receiving cone connected to a rotary drive and the pressing cone, then a cutting station consisting of a cutter head with at least one knife, then a stripping station consisting of the blowing device with at least one nozzle, next to which a suction channel opens, and then an ejector station with an ejector cylinder, which can be actuated transversely to the conveying path, for pressing off the yarn carrier from rotatable receiving cone.
- a slide 3 On a straight slide guide 1, a slide 3 is arranged to be longitudinally movable by means of two ball bushings 2. This carriage is moved by a not shown in the drawing, on the right side of the device outside the plane of the drawing, of which only the piston rod end 4 is shown, along the slide guide 1 oscillating.
- a support 5 is arranged on the slide 3 with a holding mandrel 6 rotatably mounted therein, which is designed as a receiving cone in order to hold the sleeve-shaped and conical yarn carrier 7 on the inner peripheral edge.
- the yarn carrier 7 is clamped between the receiving cone 6 and a further holding mandrel 8 which is arranged on the opposite side and is designed as a pressing cone and which can be moved back and forth in the axial direction with the aid of a pressing cylinder 9.
- the loading of the device with yarn carriers 7 in this loading station A can be automated, for which purpose, for example, a shaft (not shown in the drawing) opens above the holding mandrels 6 and 8, through which the yarn carriers come down from a storage container.
- the receiving cone 6, which is rotatably mounted in the support 5, is connected via a drive disk 10 to a drive (not shown in the drawing), for example to an electric motor fastened on the carriage 3, in order to set the yarn carrier 7 in rotation, which will be explained below.
- a knife head 12 has three knives 13 arranged one behind the other in the conveying direction, which can be adjusted steplessly and are pressed downwards by means of spring pressure onto an inner stop, so that the free ends of the knives 13 immediately, at a distance of approximately 0.05 mm, are located above the lateral surface of the yarn carrier 7 shown with dashed lines.
- the knives 13 thus move parallel to a surface line of the yarn carrier 7.
- the yarn carrier 7 In order for this to be possible, in the example of a conical yarn carrier 7 shown in the drawing, the yarn carrier 7 must be held at an angle to the carriage 1 with its central axis. For this reason, the receiving cone 6 and the pressing cone 8 are arranged with their axes obliquely to the slide guide 1. This is achieved by tilting the slide 3 with respect to the slide guide 1.
- a blowing device 14 arranged here carries two compressed air nozzles 15 arranged one behind the other in the transport direction of the yarn carrier and thus serves to fasten the nozzles and to supply the compressed air.
- the nozzles 15 are arranged obliquely against the outer surface of the yarn carrier 7 and in the direction of the free yarn carrier end facing away from the rotating holding mandrel 6. Compressed air flows out of the nozzles 15 at about 6 bar and, due to the simultaneous advancing movement of the yarn carrier 7 moved with the carriage 3 and the rotation of the yarn carrier, the previously severed thread residue 11 is stripped from the yarn carrier and is discharged through a suction channel 16 opening directly next to the blowing station aspirated.
- the carriage 3 which is continuously moved during the entire process, then moves into the adjoining ejector station D, in which an ejector cylinder 17 is arranged, which presses the yarn carrier 7 from the receiving cone 6, so that it falls into a container not shown in the drawing due to its own weight .
- the carriage 3 then travels back to the loading station A in rapid traverse in order to pick up a new thread carrier.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Entfernen des Fadenrestes von einem auf Textilmaschinen verwendeten Garnträger, auf dessen Mantelfläche nicht abgewickelte Fadenlagen vorhanden sind, wobei der Garnträger zumindest an seinem einen Stirnende in einem Halter eingespannt wird und anschliessend der eingespannt gehaltene Garnträger und ein mindestens ein Messer tragender Messerkopf relativ zueinander derart bewegt werden, dass das mindestens eine Messer mit seinem freien Ende sich zwecks Durchtrennen der fadenlagen in geringem Abstand von der Garnträger-Mantelfläche parallel zu einer Mantellinie derselben bewegt wird, dass nach Durchtrennen der Fadenlagen der Garnträger und eine Blaseinrichtung mit mindestens einer an dieser angeordneten und schräg gegen die Garnträger-Mantelfläche in Richtung des vom Haltedorn abgewandten freien Garnträgerendes gerichteten Düse relativ zueinander bewegt werden und mittels an der Düse austretender Pressluft die den zu entfernenden Fadenrest bildenden, durchtrennten Fadenlagen von dem Garnträger abgestreift werden. Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for removing the thread residue from a yarn carrier used on textile machines, on the outer surface of which there are uncoiled thread layers, the yarn carrier being clamped at least at one end in a holder and then the thread carrier held clamped and a at least one knife carrying Knife head are moved relative to each other in such a way that the free end of the at least one knife is moved parallel to a surface line of the thread carrier outer surface for the purpose of severing the thread layers at a short distance from the thread carrier surface, such that after severing the thread layers, the thread carrier and a blowing device with at least one arranged on this and directed obliquely against the thread carrier jacket surface in the direction of the free thread carrier end facing away from the holding mandrel, are moved relative to one another and by means of compressed air emerging at the nozzle, the thread number to be removed est forming, severed thread layers are stripped from the yarn carrier. The invention further relates to an apparatus for performing the method.
Um Garnträger nach ihrem Gebrauch auf einer Textilmaschine wieder verwenden zu können, müssen sie von dem noch vorhandenen Fadenrest befreit werden, um sie neu bewickeln zu können. Bei bestimmten Spinnverfahren mit zwei übereinindergesetzten Spulen an jeder Spinnstelle, deren Fäden vereinigt werden, bleibt auf dem einen der beiden Garnträger regelmässig ein mehr oder weniger grosser Fadenrest übrig, wenn der Faden von dem andern Garnträger vollkommen abgespult ist. Auf dem einen Garnträger sind daher noch eine jeweils unterschiedliche Anzahl von Fadenlagen vorhanden, die entfernt werden müssen. Man hat dafür früher eine mit viel Handarbeit verbundene Methode angewendet, bei der mit Hilfe einer Art Haspel die zunächst von Hand abgezogenen und auf den rotierenden Teil der Haspel aufgelegten Fadenenden von den auf eine Vielzahl von in Reihe neben dem rotierenden Teil angeordneten Aufnahmedornen aufgesteckten Garnträgern abgespult wurden. Dieser Vorgang dauert bei jedem Garnträger unterschiedlich lange, die Durchführung dieser Arbeit mit viel Handarbeit ist sehr mühsam und wenig ökonomisch.In order to be able to reuse yarn carriers after they have been used on a textile machine, they must be freed from the thread residue still present in order to be able to rewind them. In certain spinning processes with two bobbins placed one above the other at each spinning station, the threads of which are combined, a more or less large thread residue regularly remains on one of the two thread carriers when the thread has been completely unwound from the other thread carrier. A different number of thread layers are therefore still present on the one thread carrier, which must be removed. In the past, a method that involved a lot of manual work was used for this, with the help of a kind of reel the thread ends, which have been pulled off by hand and placed on the rotating part of the reel, have been unwound from the thread carriers attached to a plurality of holding mandrels arranged in a row next to the rotating part. This process takes a different amount of time for each thread spool. Carrying out this work with a lot of manual work is very tedious and not very economical.
Um diese aufwendige Technik zu vereinfachen und weitgehend zu mechanisieren, wird in der GB-A-1 158 584 eine Einrichtung vorgeschlagen, welche die Durchführung des eingangs beschriebenen Verfahrens ermöglicht. Trotz gewisser Erleichterungen vermag diese Lösung, welche das feste Einspannen eines Garnträgers, das Duchtrennen der auf dem Garnträger verbleibenden Fadenlagen mittels mindestens eines sich in Längsrichtung relativ zum Garnträger bewegenden Messers und das Abstreifen der duchgetrennten Fadenlagen mittels einer Blaseinrichtung beinhaltet, nur teilweise zu befriedigen. Das erreichte Resultat vermag den heutigen Anforderungen einer Spulen- und Hülsenreinigung nicht zu genügen.In order to simplify and largely mechanize this complex technology, a device is proposed in GB-A-1 158 584 which enables the method described at the outset to be carried out. Despite certain reliefs, this solution, which includes firmly clamping a thread carrier, cutting through the thread layers remaining on the thread carrier by means of at least one knife moving in the longitudinal direction relative to the thread carrier and stripping off the separated thread layers by means of a blowing device, is only partially satisfactory. The result achieved is unable to meet the current requirements of coil and tube cleaning.
Der vorliegenden Erfindung lag daher die Aufgabe zu Grunde, das vollständige Entfernen des Fadenrestes von Garnträgern noch weiter zu verbessern und dabei einen hohen Wirtschaftlichkeitsgrad bei der Fadenentfernung und Reinigung des Garnträgers zu erreichen.The present invention was therefore based on the object of further improving the complete removal of the thread remainder from thread carriers and at the same time achieving a high degree of economy in thread removal and cleaning of the thread carrier.
Zur Lösung dieser Aufgabe dient ein Verfahren mit den Massnahmen nach Anspruch 1.A method with the measures according to claim 1 serves to solve this problem.
Beim erfindungsgemässen Verfahren wird somit nach dem Durchschneiden der Garnreste auf dem Garnträger dieser in Rotation versetzt und mittels gleichzeitigem Blasen (Pressluft) und mittels Einsatz einer Saugdüse von den Fadenresten befreit. Gleichzeitig wird dabei die Oberfläche des Garnträgers auch von Staub und Kleinstfremdkörpern befreit.In the method according to the invention, after cutting through the yarn residues on the yarn carrier, the yarn carrier is set in rotation and freed from the thread residues by means of simultaneous blowing (compressed air) and by using a suction nozzle. At the same time, the surface of the yarn carrier is also freed of dust and small foreign bodies.
Die Vorrichtung zur Durchführung des Verfahrens weist die Merkmale nach Anspruch 3 auf. In dieser sind die wesentlichen Teile eine Einrichtung zum Einspannen eines Garnträgers zwischen zwei Haltedornen, ferner ein mindestens ein Messer tragender Messerkopf und eine mindestens eine Düse aufweisende Blaseinrichtung, mittels der die zuvor durch das Messer aufgetrennten Fadenlagen durch Pressluft von dem Garnträger abgestreift werden, wobei dieser durch einen der Haltedorne in schnelle Rotation versetzt wird, eine Absaugeinrichtung und eine Einrichtung zum Lösen des Garnträgers vom drehbaren Haltedorn. Der Garnträger sowie das Messer und die Blaseinrichtung müssen sich dabei mit Hilfe von Führungsmitteln relativ zueinander bewegen. In bevorzugter Ausgestaltung weisen diese Führungsmittel einen längs einer Schlittenführung oszillierend bewegbaren Schlitten auf, auf welchem ein Support mit einem den drehbaren Haltedorn bildenden Aufnahmekonus zum Halten des hülsenförmigen Garnträgers am Innenumfangsrand und mit einem Antrieb für den drehbaren Aufnahmekonus, sowie ein weiterer Support mit einem den zweiten Haltedorn bildenden Anpresskonus angeordnet sind, welch letzterer mit Hilfe eines Anpresszylinders axial bewegbar ist, um nach dem Durchtrennen der Fadenlagen auf dem Garnkörper von diesem wegbewegt zu werden, damit über das dann freie Ende des Garnträgers die durchgetrennten Fadenlagen bei schneller Rotation des Garnträgers mit Hilfe der Blasdüse von dem Garnträger abgestreift werden können und ungehindert in einen im Bereich des Garnträgerendes mündenden Absaugkanal gelangen können. In bevorzugter Ausgestaltung erstreckt sich daher die Schlittenführung entlang einer geradlinigen Förderstrecke, an welcher in Reihe hintereinander eine Beladestation mit Mitteln zum automatischen Einspannen eines Garnträgers zwischen den mit einem Drehantrieb verbundenen Aufnahmekonus und den Anpresskonus, anschliessend eine aus einem Messerkopf mit mindestens einem Messer bestehende Schneidestation, anschliessend eine aus der Blaseinrichtung mit mindestens einer Düse bestehende Abstreifstation, neben welcher ein Absaugkanal mündet, und anschliessend eine Auswerferstation mit einem quer zur Förderstrecke betätigbaren Auswerferzylinder zum Abdrücken des Garnträgers von drehbaren Aufnahmekonus angeordnet sind.The device for performing the method has the features of
Nachfolgend werden das Verfahren und die Vorrichtung in einer bevorzugen Ausführungsform anhand der Zeichnung näher beschrieben. Die einzige Figur zeigt die Vorrichtung schematisch und nur deren wesentliche Bestandteile.The method and the device are described in more detail in a preferred embodiment with reference to the drawing. The single figure shows the device schematically and only its essential components.
Auf einer geradlinigen Schlittenführung 1 ist mittels zweier Kugelbüchsen 2 ein Schlitten 3 längsbeweglich angeordnet. Dieser Schlitten wird durch einen in der Zeichnung nicht dargestellten, auf der rechten Seite der Vorrichtung ausserhalb der Zeichenebene anschliessenden pneumatischen Zylinder, von dem nur das Kolbenstangenende 4 dargestellt ist, längs der Schlittenführung 1 oszi ierend bewegt. Auf dem Schlitten 3 ist ein Support 5 mit einem in diesem drehbar gelagerten Haltedorn 6 angeordnet, der als Aufnahmekonus ausgebildet ist, um den hülsenförmigen und konischen Garnträger 7 am Innenumfangsrand festzuhalten. Der Garnträger 7 wird zwischen dem Aufnahmekonus 6 und einem auf der gegenüber liegenden Seite angeordneten weiteren, als Anpresskonus ausgebildeten Haltedorn 8 eingespannt, der mit Hilfe eines Anpresszylinders 9 in axiale Richtung hin und her bewegbar ist. Das Beladen der Vorrichtung mit Garnträgern 7 in dieser Beladestation A lässt sich automatisieren, zu welchem Zweck beispielsweise oberhalb der Haltedorne 6 und 8 ein in der Zeichnung nicht dargestellter Schacht mündet, durch den die Garnträger aus einem Vorratsbehälter nach unten gelangen.On a straight slide guide 1, a
Der in dem Support 5 drehbar gelagerte Aufnahmekonus 6 steht über eine Antriebsscheibe 10 mit einem in der Zeichnung nicht dargestellten Antrieb, beispielsweise mit einem auf dem Schlitten 3 befestigten Elektromotor in Verbindung, um den Garnträger 7 in Drehung zu versetzen, was nachfolgend noch erläutert wird.The
Nach dem Einspannen des Garnträgers 7 zwischen die beiden Haltedornen 6 und 8 in der Beladestation A muss zunächst der auf dem Garnträger 7 noch vorhandene Fadenrest 11, der in einer mehr oder weniger grossen Anzahl von Fadenlagen auf der Mantelfläche des Garnträgers 7 vorhanden ist, ganz aufgeschnitten werden. Zu diesem Zweck wird der Schlitten 3 mit Hilfe der Kolbenstange 4 des in der Zeichnung nicht dargestellten Pneumatikzylinders durch die Schneidestation B hindurch bewegt. Ein Messerkopf 12 weist unten drei in Förderrichtung hintereinander angeordnete Messer 13 auf, die stufenlos eingestellt werden können und mittels Federdruck nach unten auf einen inneren Anschlag gedrückt werden, damit die freien Enden der Messer 13 sich unmittelbar,in einem Abstand von ca. 0.05 mm, oberhalb der Mantelfläche des mit gestrichelten Linien dargestellten Garnträgers 7 befinden. Die Messer 13 bewegen sich dabei also parallel zu einer Mantellinie des Garnträgers 7. Damit dies möglich ist,muss bei einem im in der Zeichnung dargestellten Beispiel konischen Garnträger 7 dieser mit seiner Mittelachse unter einem Winkel schräg zum Schlitten 1 gehalten sein. Aus diesem Grund sind der Aufnahmekonus 6 und der Anpresskonus 8 mit ihren Achsen schräg zur Schlittenführung 1 angeordnet. Dies ist durch Schrägstellung des Schlittens 3 in bezug auf die Schlittenführung 1 erreicht.After the
Beim Durchtrennen der Fadenlagen 11 auf dem Garnträger 7 mittels der Messer 13 ist der Garnträger festgehalten und nach Beendigung des Durchtrennens der Fadenlagen wird dann während der Weiterbewegung des Schlittens 3 der Anpresskonus 8 mit Hilfe des Anpresszylinders 9 von dem Garnträger 7 getrennt, sodass dieser nur noch auf dem Aufnahmekonus 6 festsitzt. Gleichzeitig wird dieser Aufnahmekonus über die Antriebsscheibe und den Antrieb wie vorstehend beschrieben in Rotation versetzt, sodass der Garnträger 7 mit etwa 900 U/Min. rotiert. Der rotierende Garnträger 7 wird dann unter der in der Zeichnung nach links anschliessenden Blasstation C hindurchbewegt. Eine hier angeordnete Blaseinrichtung 14 trägt unten zwei in Transportrichtung des Garnträgers hintereinander angeordnete Pressluftdüsen 15 und dient somit zur Befestigung der Düsen und zur Zuleitung der Pressluft. Die Düsen 15 sind schräg gegen die Mantelfläche des Garnträgers 7 und in Richtung des vom rotierenden Haltedorn 6 abgewandten freien Garnträgerendes angeordnet. Aus den Düsen 15 strömt Pressluft mit ca. 6 bar und durch die gleichzeitige Vorschubbewegung des mit dem Schlitten 3 weiterbewegten Garnträgers 7 und die Rotation des Garnträgers wird der zuvor durchtrennte Fadenrest 11 von dem Garnträger abgestreift und wird durch einen unmittelbar neben der Blasstation mündenden Absaugkanal 16 abgesaugt.When severing the
Der während des ganzen Vorgangs kontinuierlich weiter bewegte Schlitten 3 fährt sodann in die anschliessende Auswerferstation D, in welcher ein Auswerferzylinder 17 angeordnet ist, der den Garnträger 7 von dem Aufnahmekonus 6 abdrückt, sodass dieser durch das Eigengewicht in einen in der Zeichnung nicht dargestellten Behälter fällt. Der Schlitten 3 fährt anschliessend im Eilgang in die Beladestation A zurück, um einen neuen Garnträger aufzunehmen.The
