Abstract

The device has a housing (1) which possesses two mutually parallel bearing bodies (2, 3), between which are pivotably mounted a lifting-out unit (8) in a first plane parallel to the bearing bodies and, next to it, a unit (9) for the attachment of a new traveller in a second plane, parallel to the first, by means of links (31, 32; 33-35; 61, 62, 63) fastened pivotably to the two bearing bodies (2, 3). The links are pivotably movable by means of eccentric cams (39, 42; 66, 69) arranged on a common drive shaft (10), in order to move each of the two units (8, 9) between an operating position and a position of rest. The housing (1) movable along a ring rail (4) of a spinning machine lifts, by means of the lifting-out unit (8), a traveller (7), to be exchanged, out of the spinning ring (6) arranged on the ring rail (4), and subsequently a new traveller is engaged into the spinning ring (6) by the unit (9) for the attachment of a new traveller from a magazine rod (74) arranged in this unit. Because of the small distance between the disengagement and engagement position in the longitudinal direction of the ring rail (4), the traveller change can take place on the spinning ring (6) in the same position of the device. New travellers (7) are fed continuously to the magazine rod (74) from a bobbin (20) on which a cord (21) having travellers contained on it is wound. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Bekanntlich müssen Ringläufer an Spinnmaschinen in bestimmten Zeitabständen ausgewechselt werden, da sie einem Verschleiss unterliegen, der Fadenbrüche zur Folge hat, die vermieden werden sollen. Ausserdem sind Ringläufer auch beim Auftreten irgendeines Defekts unabhängig von der turnusmässig durchzuführenden Massnahme individuell auszuwechseln.As is known, ring rotors on spinning machines have to be replaced at certain intervals since they are subject to wear, which results in thread breaks which are to be avoided. In addition, ring rotors must also be replaced individually if any defect occurs, irrespective of the regular measure.

Bei jedem Ringläuferwechsel sind verschiedene Teiloperationen durchzuführen, und zwar muss zunächst nach Stillsetzung der Spinnmaschine der an beliebiger Stelle des Spinnrings stehende Ringläufer nach vorn gebracht werden, er muss sodann ausgeklinkt werden, wobei der Faden frei wird und eine undefinierte Stellung einnimmt, und es muss sodann ein neuer Ringläufer in den Spinnring eingeklinkt werden, woraufhin dann der Faden in den neuen Ringläufer eingehängt werden muss. Diese verschiedenen Teiloperationen wurden bisher entweder manuell, unter Zuhilfenahme einfacher Werkzeuge, wie beispielsweise eines Hakens zum Ausklinken und Einklinken eines Ringläufers, durchgeführt, oder auch mit Hilfe von weiterentwickelten, zangenförmigen Werkzeugen für das Einklinken eines neuen Ringläufers von einem Magazin (vgl. GB-A-2 226 337). Die von Hand geführten Werkzeuge verlangen eine mehr oder weniger manuelle Geschicklichkeit, die nur durch Uebung erreichbar ist.Each time the ring traveler is changed, different sub-operations have to be carried out.First, after stopping the spinning machine, the ring traveler standing at any point on the spinning ring has to be brought forward, then it has to be released, the thread becomes free and assumes an undefined position, and it must then a new ring traveler must be latched into the spinning ring, whereupon the thread must then be hung in the new ring traveler. Until now, these various sub-operations have either been carried out manually, with the aid of simple tools, such as a hook for releasing and engaging a ring traveler, or with the help of further developed, plier-shaped tools for engaging a new ring traveler from a magazine (cf.GB-A -2 226 337). The hand-operated tools require a more or less manual dexterity that can only be achieved through practice.

Aus DE-A-20 51 754 ist eine Ansetzvorrichtung zum automatischen Ringläuferwechsel an einer Ringspinnmaschine bekannt. Bei jedem Ansetzen eines Fadens nach einem Fadenbruch wird der alte Ringläufer vom Spinnring durch einen Läuferauswerfer ausgeworfen und ein neuer Ringläufer durch eine Aussetzvorrichtung in den Spinnring eingedrückt. Der Bewegungsmechanismus des Läuferauswerfers und der Aufsetzvorrichtung sind dergestalt, dass die Bewegungen nur hintereinander durchgeführt werden können. Obwohl eine Fangplatte mit einem Behälter für die alten Ringläufer vorgesehen ist, können die alten Ringläufer unkontrolliert in eine andere Richtung weggesprengt werden oder auch in Teilen auseinanderbrechen. Es besteht dadurch die Gefahr, dass diese Ringläufer oder Teile davon in die Ringspinnmaschine gelangen und deren Funktionstüchtigkeit beeinträchtigen können, was zu Produktionsausfällen führen kann.From DE-A-20 51 754 an attachment device for the automatic change of ring traveler on a ring spinning machine is known. Each time a thread is attached after a thread break, the old ring traveler is ejected from the spinning ring by a rotor ejector and a new ring traveler is pushed through a release device is pressed into the spinning ring. The movement mechanism of the rotor ejector and the placement device are such that the movements can only be carried out one after the other. Although a catch plate with a container is provided for the old ring travelers, the old ring travelers can be blown away in a different direction in an uncontrolled manner or can also break apart in parts. There is therefore a risk that these ring rotors or parts thereof can get into the ring spinning machine and impair their functionality, which can lead to production downtimes.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, das Auswechseln von Ringläufern an Spinn- oder Zwirnringen so zu mechanisieren, dass die alten Ringläufer in einer zuverlässigen Art ohne den Spinn- oder Zwirnring zu beschädigen entfernt und entsorgt, werden können.The object of the present invention was therefore to mechanize the replacement of ring travelers on spinning or twisting rings in such a way that the old ring travelers can be removed and disposed of in a reliable manner without damaging the spinning or twisting ring.

Zur Lösung dieser Aufgabe weist die Vorrichtung die Merkmale nach Anspruch 1, 15 oder 16 auf. Die Vorrichtung gemäss Anspruch 1 oder 16 kann zwei unmittelbar nebeneinander arbeitende Geräte zum Ausklinken eines auszuwechselnden Ringläufers und zum Einklinken eines neuen Ringläufers enthalten, welche Geräte vorzugsweise durch eine gemeinsame Welle in ihren Bewegungsabläufen gesteuert werden. Die Vorrichtung kann ohne Unterbrechung mit einem mehrere tausend Ringläufer enthaltenden Magazin arbeiten, und damit die ausgeklinkten Ringläufer nicht versehentlich auf den Boden oder in die hergestellte Ware gelangen, werden sie in der Vorrichtung in einen Sammelbehälter hinein entsorgt.To achieve this object, the device has the features of claim 1, 15 or 16. The device according to claim 1 or 16 can contain two devices working next to each other for disengaging a ring traveler to be exchanged and for engaging a new ring traveler, which devices are preferably controlled in their movements by a common shaft. The device can work without interruption with a magazine containing several thousand ring travelers, and so that the notched ring travelers do not accidentally get onto the floor or into the manufactured goods, they are disposed of in the device in a collecting container.

Vorzugsweise soll sich die Vorrichtung mit einem Anspinnwagen zusammenkuppeln lassen, welcher zum Beheben von Fadenbrüchen an einer Spinnmaschine entlang fahrbar angeordnet ist und welcher in Zusammenarbeit mit der Vorrichtung bei Durchführung des Ringläuferwechsels den Faden in den neuen Ringläufer einzuhängen oder einen getrennten Faden wieder zu verbinden in der Lage ist. Der Vorteil ist die Unabhängigkeit von mehr oder weniger Handgeschicklichkeit aufweisendem Bedienungspersonal und die Verfügbarkeit der Vorrichtung während eines 24-Stunden-Tages sowie der immer gleichbleibende, zuverlässige und schnelle Ablauf aller Teiloperationen des Ringläuferwechsels.The device should preferably be able to be coupled together with a piecing carriage, which is arranged to be movable along a spinning machine for eliminating thread breaks and which in cooperation with the Device when performing the ring traveler change the thread in the new ring traveler or is able to reconnect a separate thread. The advantages are the independence of more or less skillful operating personnel and the availability of the device during a 24-hour day, as well as the constant, reliable and fast execution of all partial operations of the ring traveler change.

Für die Bewegung des Aushebegeräts 8 und des Geräts 9 zum Anbringen eines neuen Ringläufers dient eine die beiden Lagerkörper 2 und 3 quer durchsetzende gemeinsame Steuerwelle 10. Diese wird mittels einer auf der Welle sitzenden Riemenscheibe 11 und eines Antriebsriemens 12 durch einen Motor 24 angetrieben. Am Gehäuse 1 ist ferner seitlich nebem dem Lagerkörper 2 ein Sammelbehälter 13 für die durch das Aushebegerät 8 entfernten Ringläufer fest angeordnet. Das Positionieren des Ringläufers 7 auf dem Spinnring 6 in die richtige Stellung zum Ausheben und die Wegführung des Ringläufers in den Sammelbehälter 13 geschieht mit Hilfe von Druckluft, zu welchem Zweck drei 3/2-Wegeventile 14, 15 und 16 zu verschiedenen Zeiten während eines Arbeitszyklus mit Hilfe von Steuernocken 17, 18 und 19 betätigt werden, welche auf der hinter dem Riementrieb 11, 12 verlängerten gemeinsamen Steuerwelle 10 angeordnet sind.In the schematic plan view from above according to FIG. 1, the device has a housing 1, which in particular by means of spacer bolts, not shown, having wall-shaped bearing bodies 2 and 3 held parallel to one another. The housing can be moved along a spinning machine by means not shown in the drawing, directly in front of the ring bench 4 and preferably in direct connection with a piecing carriage. In Fig. 3, an end region of the spindle bank with two spinning rings 5 and 6 is shown in plan view. A ring traveler 7 present on the spinning ring 6 is to be replaced by means of the device. For this purpose, the device has a lifting device 8 which can be moved in a vertical plane within the housing 1 which has the two bearing bodies 2 and 3 and which first comes into action in order to lift a ring traveler to be replaced. A device 9 for attaching a new ring traveler is also movably arranged within the housing 1 in a second plane parallel to the first. For the movement of the lifting device 8 and the device 9 for attaching a new ring traveler, there is a common control shaft 10 passing through the two bearing bodies 2 and 3. This is driven by a motor 24 by means of a pulley 11 seated on the shaft and a drive belt 12. On the housing 1, a collecting container 13 for the ring traveler removed by the lifting device 8 is also arranged laterally next to the bearing body 2. The positioning of the ring traveler 7 on the spinning ring 6 in the correct position for lifting and the path of the ring traveler in the collecting container 13 is done with the aid of compressed air, for which purpose three 3/2-way valves 14, 15 and 16 at different times during a working cycle with the aid of control cams 17, 18 and 19 which are operated on the joint which is extended behind the belt drive 11, 12 Control shaft 10 are arranged.

Die dem Gerät 9 zum Anbringen eines neuen Ringläufers zuzuführenden Ringläufer kommen von einer Magazinspule 20, die seitlich am Gehäuse 1 angeordnet ist und die einen sog. Strap 21 aufgewickelt enthält, der aus einer Schnur mit einer Vielzahl darauf aufgereihten Ringläufern besteht, die in dem Gerät 9 zum Anbringen eines neuen Ringläufers von der Schnur getrennt werden, welche dann auf einer zweiten Spule 22 wieder aufgewickelt wird, die auf einer im Gehäuse 2, 3 gelagerten Welle 23 angeordnet und drehend antreibbar ist.The ring travelers to be supplied to the device 9 for attaching a new ring traveler come from a magazine spool 20 which is arranged on the side of the housing 1 and which contains a so-called strap 21 which consists of a cord with a plurality of ring travelers arranged thereon, which are in the device 9 for attaching a new ring traveler are separated from the cord, which is then rewound on a second spool 22 which is arranged on a shaft 23 mounted in the housing 2, 3 and can be driven in rotation.

Zum Auswechseln eines Ringläufers muss zunächst das Aushebegerät 8 in Aktion treten. Dieses ist in Fig. 2 schematisch und in Bezug auf seine Bewegung zwischen der Betriebsstellung und Ruhestellung dargestellt. Das Aushebegerät 8 weist als Aufnehmer für einen Ringläufer ein Kopfstück 30 auf, das in der Betriebsstellung in ausgezogener Linie und in der Ruhestellung in strichpunktierten Linien dargestellt ist. Die Bewegung des Kopfstücks 30 erfolgt durch ein aus den beiden gelenkig miteinander verbundenen Hebeln 31, 32 bestehendes erstes Lenkersystem und durch ein aus den gelenkig miteinander verbundenen Hebeln 33, 34 und 35 bestehendes zweites Lenkersystem. Die Hebel 31 und 33 sind am Kopfstück 30 angelenkt. Der Hebel 32 ist mittels einer Achse 36 am Lagerkörper 3 des Gehäuses schwenkbar gelagert und trägt ferner eine Rolle 37, die mittels einer Feder 38 gegen einen Exzenternocken 39 angedrückt ist, welcher auf der durch den Antriebsriemen 12 angetriebenen gemeinsamen Steuerwelle 10 angeordnet ist. Durch die während des Arbeitszyklus eine Umdrehung ausführende Steuerwelle 10 gelangt die an den Exzenternocken 39 angedrückte Rolle 37 einmal in die strichpunktierte Stellung 37a und das Kopfstück 30 in die strichpunktierte Ruhestellung.To replace a ring traveler, the lifting device 8 must first take action. This is shown schematically in FIG. 2 and in relation to its movement between the operating position and the rest position. The lifting device 8 has a head piece 30 as a receiver for a ring traveler, which is shown in the operating position in a solid line and in the rest position in dash-dotted lines. The movement of the head piece 30 takes place by means of a first link system consisting of the two levers 31, 32 articulated to one another and by a second link system consisting of the levers 33, 34 and 35 articulated to one another. The levers 31 and 33 are articulated on the head piece 30. The lever 32 is pivotally mounted on the bearing body 3 of the housing by means of an axis 36 and also carries a roller 37 which is pressed by means of a spring 38 against an eccentric cam 39 which is arranged on the common control shaft 10 driven by the drive belt 12. Through the control shaft, which makes one revolution during the working cycle 10 the roller 37 pressed against the eccentric cam 39 once reaches the dot-dash position 37a and the head piece 30 reaches the dot-dash rest position.

Zum Ausheben des Ringläufers 7 vom Spinnring 6 ist eine kurze, horizontale Zugbewegung erforderlich. Zu diesem Zweck ist der mittlere Hebel 34 des aus den Hebeln 33, 34 und 35 bestehenden zweiten Lenkersystems mittels einer Achse 40 am Lagerkörper 3 schwenkbar gelagert und wird gegen die Kraft einer am Lagerkörper 3 und am unteren Hebelende abgestützten Druckfeder 41 geringfügig in der Zeichnung nach links verschwenkt, wenn die Stellung des Hebels 35 durch einen auf der gemeinsamen Steuerwelle 10 angeordneten Exzenternocken 42 und die gegen diesen Nocken anliegende und am Ende des Hebels 35 angeordnete Rolle 43 verändert wird. Die dann erreichte Stellung ist strichpunktiert dargestellt.A short, horizontal pulling movement is required to lift the ring traveler 7 from the spinning ring 6. For this purpose, the middle lever 34 of the second link system consisting of the levers 33, 34 and 35 is pivotally mounted on the bearing body 3 by means of an axis 40 and is slightly offset in the drawing against the force of a compression spring 41 supported on the bearing body 3 and on the lower lever end swiveled to the left when the position of the lever 35 is changed by an eccentric cam 42 arranged on the common control shaft 10 and the roller 43 lying against this cam and arranged at the end of the lever 35. The position then reached is shown in dash-dot lines.

Zum Ausklingen eines Ringläufers 7, wie in Fig. 5 dargestellt, wird das Kopfstück 30 des Aushebegeräts 8 gegen den Spinnring 6 nach unten geschwenkt. Der Ringläufer kann sich im Aufsetzbereich des Kopfstücks befinden und muss vorerst aus diesem Bereich wegbefördert werden, bevor das Kopfstück 30 auf den Spinnring aufsetzt. Zu diesem Zweck tritt zunächst eine aus dem Kopfstück 30 nach aussen sich erstreckende Druckluft-Blasdüse 45 in Aktion und bläst einen Luftstrom in Richtung des Pfeils C₁ in Fig. 2., damit ein eventuell im Aufsetzbereich vorhandener Ringläufer eine Stellung ausserhalb dieses Aufsetzbereiches, beispielsweise die Stellung wie in Fig. 3 dargestellt einnimmt. Diese Figur zeigt nur ausschnittweise das Kopfstück 30 in der Stellung gemäss Fig. 2 von oben gesehen.To end a ring traveler 7, as shown in FIG. 5, the head piece 30 of the lifting device 8 is pivoted downwards against the spinning ring 6. The ring traveler can be located in the attachment area of the head piece and must first be removed from this area before the head piece 30 attaches to the spinning ring. For this purpose, a compressed air blowing nozzle 45, which extends outward from the head piece 30, first comes into action and blows an air flow in the direction of the arrow C 1 in FIG Position as shown in Fig. 3 assumes. This figure shows only a portion of the head piece 30 in the position shown in FIG. 2 seen from above.

Das in Fig. 3 von oben und in Fig. 4 von der Unterseite gesehen dargestellte Kopfstück 30 trägt seitlich unten einen flachen, sich zum Ende verjüngenden kurzen Dorn 46. Mit diesem Dorn 46 wirkt eine am Kopfstück seitlich mittels eines Schwenkzapfens 47 schwenkbar gelagerte zweiarmige Klemmbacke 48 zusammen. Der ein Arm 49 der Klemmbacke ist von oben gegen den Dorn 46 bzw. gegen einen auf diesem befindlichen Ringläufer unter der Wirkung einer den anderen Arm 50 der Klemmbacke ständig beaufschlagenden Druckfeder 51 angedrückt. Zweimal während eines Arbeitszyklus muss diese Klemmbacke freigegeben werden, sodass der Arm 49 vom Dorn 46 abhebt. Die Freigabe erfolgt durch eine im Kopfstück 30 angeordnete kleine Kolben-ZylinderEinheit 52, die druckluftbetätigt ist, sodass die Klemmbacke 48 in eine Offenstellung verschwenkt wird. Hierzu dient ein Druckluftanschluss A am Kopfstück 30. Die Druckluftleitungen sind nicht dargestellt. Von den weiteren Druckluftanschlüssen B und C führt ein Kanal vom Anschluss C durch das Kopfstück zur Düse 45, um wie bereits beschrieben den Ringläufer aus dem Aufsetzbereich des Kopfstücks zu transportieren, und vom gleichen Kanal führt ein weiterer Kanal 45a zu einer oberhalb des Dorns 46 mündenden Ausblasöffnung 45b, aus der ein Luftstrahl parallel zum Dorn 46 austritt (Fig. 2b).The head piece 30 shown in FIG. 3 from above and in FIG. 4 from the underside has a flat, short mandrel 46 tapering towards the end at the bottom. This mandrel 46 acts on the head piece on the head piece, which is pivoted laterally by means of a pivot pin 47 48 together. One arm 49 of the jaw is pressed from above against the mandrel 46 or against a ring traveler located thereon under the action of a compression spring 51 which constantly acts on the other arm 50 of the jaw. This jaw must be released twice during a work cycle so that the arm 49 lifts off the mandrel 46. The release takes place through a small piston-cylinder unit 52 arranged in the head piece 30, which is actuated by compressed air, so that the clamping jaw 48 is pivoted into an open position. A compressed air connection A on the head piece 30 is used for this purpose. The compressed air lines are not shown. From the further compressed air connections B and C, a channel leads from the connection C through the head piece to the nozzle 45 in order to transport the ring traveler from the mounting area of the head piece, as already described, and from the same channel another channel 45 a leads to an opening above the mandrel 46 Blow-out opening 45b, from which an air jet emerges parallel to the mandrel 46 (FIG. 2b).

Wenn durch Betätigung der Klemmbacke 48 deren Arm 49 vom Dorn 46 abgehoben ist, erfolgt über den Druckluftanschluss B am Kopfstück 30 ein weiterer Bewegungsimpuls auf den beispielsweise in einer Stellung gemäss Fig. 3 sich befindenden Ringläufer 7 mittels eines Druckluftstroms aus der Düse 54, die an den Druckluftanschluss B angeschlossen ist, und die innenseitig des Spinnrings 6 in tangentialer Richtung so mündet, dass ein innenseitig im Spinnring 6 gemäss dem Pfeil B geführter Luftstrom den Ringläufer 7 auf den am Kopfstück angeordneten Dorn 46 befördert, woraufhin die kurzzeitig mittels der Kolben-Zylinder-Einheit 52 freigegebene Klemmbacke 48 den Ringläufer auf dem Dorn 46 festklemmt.If, by actuating the clamping jaw 48, its arm 49 is lifted from the mandrel 46, a further movement impulse occurs on the ring traveler 7, for example in a position according to FIG. 3, by means of a compressed air flow from the nozzle 54 via the compressed air connection B on the head piece 30 the compressed air connection B is connected, and which opens on the inside of the spinning ring 6 in the tangential direction so that an inside of the spinning ring 6 Air flow guided according to arrow B conveys the ring traveler 7 onto the mandrel 46 arranged on the head piece, whereupon the clamping jaw 48 released briefly by means of the piston-cylinder unit 52 clamps the ring traveler on the mandrel 46.

In den Figuren 5 und 6 sind zwei weitere Bewegungsphasen des Kopfstücks 30 beim Entfernen eines Ringläufers 7 vom Spinnring 6 dargestellt. Man erkennt den mittels der Klemmbacke 48 festgehaltenen Ringläufer 7, der gemäss Fig. 5 zunächst durch eine Schwenkbewegung des Kopfstücks 30 (gegenüber Fig. 2a veränderte Stellung) ausgeklinkt wird und anschliessend gemäss Fig. 6 radial vom Spinnring 6 weg bewegt wird, um das Hochschwenken des Kopfstückes 30 in die Ausserbetriebsstellung nachfolgend zu ermöglichen. In dieser Stellung wird die Klemmbacke 48 über den Druckluftanschluss A erneut betätigt, um den festgeklemmten Ringläufer freizugeben. Ferner wird nochmals über den Druckluftanschluss C durch einen im Innern des Kopfstückes 30 verlaufenden Kanal 45a, (Fig. 2b), an welchem auch die Leitung zur Düse 45 angeschlossen ist, was nicht dargestellt ist, Druckluft durch eine am Kopfstück unten über dem Dorn 46 vorhandene Ausblasöffnung 45 b in Richtung des Pfeils C₂ (Fig. 2, 2b, 4) gegen den freigegebenen Ringläufer geblasen, so dass diese quer über das daneben befindliche Gerät 9 zum Anbringen eines neuen Ringläufers in den Sammelbehälter 13 transportiert wird.FIGS. 5 and 6 show two further phases of movement of the head piece 30 when a ring traveler 7 is removed from the spinning ring 6. One recognizes the ring traveler 7 held by means of the clamping jaw 48, which, according to FIG. 5, is first released by a pivoting movement of the head piece 30 (position changed compared to FIG. 2a) and is then moved radially away from the spinning ring 6 according to FIG. 6 in order to pivot upward to enable the head piece 30 into the non-operating position below. In this position the clamping jaw 48 is actuated again via the compressed air connection A in order to release the clamped ring traveler. Furthermore, compressed air is fed through the compressed air connection C through a channel 45a (FIG. 2b) running inside the head piece 30, to which the line to the nozzle 45 is also connected, which is not shown Existing blow-out opening 45 b in the direction of arrow C₂ (Fig. 2, 2b, 4) blown against the released ring traveler so that it is transported across the adjacent device 9 for attaching a new ring traveler in the collecting container 13.

In Fig. 14 ist das Prinzip der Nockensteuerung für die drei am Kopfstück 30 angeordneten Druckluftanschlüsse A, B und C schematisch dargestellt. Aus der durch Pfeile angedeuteten Umlaufrichtung der Nocken erkennt man, dass zuerst der Doppelnocken 17 das nur mit einer Rolle dargestellte Ventil 14 betätigt, damit der Luftstrahl C einen Ringläufer aus dem Aufsetzbereich des Kopfs 30 des Aushebegeräts wegbefördert. Anschliessend betätigt der Doppelnocken 19 das Ventil 16, um die Klemmbacke 48 freizugeben, woraufhin dann der einfache Nocken 18 den tangentialen Luftstrom B an der Innenseite des Spinnrings auslöst. Am Ende des Arbeitszyklus wird dann wieder der Doppelnocken 17 für den aus der Ausblasöffnung 45b austretenden Luftstrom C₂ zum Wegblasen des Ringläufers in den Sammelbehälter 13 und der Doppelnocken 19 für die Freigabe der Klemmbacke 48 betätigt, um den Ringläufer wegblasen zu können.The principle of the cam control for the three compressed air connections A, B and C arranged on the head piece 30 is shown schematically in FIG. 14. From the direction of rotation of the cams indicated by arrows you can see that first the double cam 17 actuates the valve 14 shown with only one roller, so that the air jet C conveys a ring traveler out of the mounting area of the head 30 of the lifting device. The double cam 19 then actuates the valve 16 in order to release the clamping jaw 48, whereupon the simple cam 18 then triggers the tangential air flow B on the inside of the spinning ring. At the end of the working cycle, the double cam 17 is then actuated again for the air flow C₂ emerging from the blow-out opening 45b to blow off the ring traveler into the collecting container 13 and the double cam 19 for releasing the clamping jaw 48 in order to blow the ring traveler away.

Die in Fig. 1 in Draufsicht dargestellte Vorrichtung weist neben dem in einer ersten vertikalen Ebene bewegbaren Aushebegerät 8 das in einer dazu parallelen Ebene bewegbare Gerät 9 zum Anbringen eines neuen Ringläufers auf. Dieses in Fig. 7 bis Fig. 11 näher dargestellte Gerät wird aus der in Fig. 7 dargestellte Ausserbetriebsstellung nach dem gleichen Prinzip wie das Aushebegerät mittels Nockensteuerung in die Betriebsstellung und zurück bewegt.The device shown in plan view in FIG. 1 has, in addition to the lifting device 8 movable in a first vertical plane, the device 9 movable in a plane parallel thereto for attaching a new ring traveler. This device, which is shown in more detail in FIGS. 7 to 11, is moved from the inoperative position shown in FIG. 7 according to the same principle as the lifting device by means of cam control into the operating position and back.

Eine Führungsplatte 60 ist in bezug auf das aus den Lagerkörpern 2, 3 bestehende Gehäuse 1 zur Ringbank 4 der Spinnmaschine schräg abwärts geneigt an einem aus dem Hebel 61 bestehenden ersten Lenker und einem aus den beiden Hebeln 62, 63 bestehenden zweiten Lenkersystem gelenkig befestigt. Der Lenker 61 ist mittels der durchgehenden Achse 36 am Lagerkörper 2, 3 schwenkbar gelagert und eine am Lenker 61 angeordnete Rolle 65 liegt gegen einen Exzenternocken 66 an, welcher auf der gemeinsamen Steuerwelle 10 angeordnet ist und bei seinem Umlauf bewirkt, dass die Führungsplatte 60 und somit das Gerät 9 zum Anbringen eines neuen Ringläufers vor- und zurückbewegt wird. Zum Einhängen eines neuen Ringläufers auf einen Spinnring ist eine kurze Auf- und Abbewegung notwendig und diese erfolgt durch das aus den Hebeln 62, 63 bestehende Lenkersystem, in welchem der Hebel 63 mittels einer Schwenkachse 67 am Lagerkörper 3 gelagert ist und am Ende eine Rolle 68 trägt, die gegen einen weiteren auf der gemeinsamen Steuerwelle 10 angeordneten Exzenternocken 69 angedrückt ist. Der annähernd waagrechte Hebel 63 bewirkt daher bei einem Exzenternocken-Umlauf eine Hubbewegung des Hebels 62 und erteilt damit der Führungsplatte 60 eine Auf- und Abbewegung.A guide plate 60 is articulated with respect to the housing 1 consisting of the bearing bodies 2, 3 inclined obliquely downwards to the ring bank 4 of the spinning machine on a first link consisting of the lever 61 and a second link system consisting of the two levers 62, 63. The link 61 is pivotally mounted on the bearing body 2, 3 by means of the continuous axis 36 and a roller 65 arranged on the link 61 bears against an eccentric cam 66 which is on the common control shaft 10 is arranged and in its circulation causes the guide plate 60 and thus the device 9 to move a new ring traveler back and forth. A short up and down movement is necessary to hang a new ring traveler on a spinning ring and this is done by the link system consisting of the levers 62, 63, in which the lever 63 is mounted on the bearing body 3 by means of a pivot axis 67 and at the end a roller 68 carries, which is pressed against another arranged on the common control shaft 10 eccentric cam 69. The approximately horizontal lever 63 therefore causes a lifting movement of the lever 62 when the eccentric cam rotates and thus gives the guide plate 60 an up and down movement.

An der Führungsplatte 60 ist ein langgestreckter Führungskörper 70 längsbeweglich gehalten und eine Relativbewegung zwischen Führungsplatte und Führungskörper ist gegen die Wirkung einer zwischen diesen beiden sich abstützenden Druckfeder 71 möglich. Mit dem Führungskörper 70 ist über eine vordere Lasche 72 und eine hintere Lasche 73 eine parallel zum Führungskörper 70 sich erstreckende Magazinstange 74 fest verbunden, auf welcher eine Vielzahl von Ringläufern 7 aufgereiht sind. Die Ringläufer werden mit der Schnur 21, die auf der in Fig. 1 dargestellten Spule 20 aufgewickelt ist und die eine Vielzahl von aufgereihten Ringläufern 7 trägt, der Magazinstange 74 zugeführt. Die auch als Strap bezeichnete und Ringläufer enthaltende Schnur 21 ist über eine am Ende des Führungskörpers 70 drehbar gelagerte Umlenkrolle 75 geführt und läuft entlang dem unterseitig genuteten Endabschnitt 76 der Magazinstange 74, wobei sich die Ringläufer von der in der Nut laufenden Schnur trennen, die dann über eine Umlenkführung 77 zu einer Strap-Transportwelle 78 läuft, welche durch einen aussen am Gehäuse angeflanschten Motor 79 angetrieben ist (Fig. 1). Die mit einer Gegendruckrolle 80 zusammenwirkende Strap-Antriebswelle 78 wird durch den Motor 79 immer dann angetrieben, wenn ein oberhalb der Magazinstange 74 angeordneter Läufer-Füllstandsinitiator 81 ein Signal gibt, dass der Soll-Füllstand auf der Magazinstange unterschritten ist.An elongated guide body 70 is held on the guide plate 60 in a longitudinally movable manner and a relative movement between the guide plate and the guide body is possible against the action of a compression spring 71 supported between these two. A magazine rod 74, which extends parallel to the guide body 70 and on which a plurality of ring travelers 7 are lined up, is fixedly connected to the guide body 70 via a front link 72 and a rear link 73. The ring rotors are fed to the magazine rod 74 with the cord 21, which is wound on the spool 20 shown in FIG. 1 and which carries a plurality of ring rotors 7 lined up. The cord 21, which is also referred to as a strap and contains ring travelers, is guided over a deflection roller 75 which is rotatably mounted at the end of the guide body 70 and runs along the end section 76 of the magazine rod 74 which is grooved on the underside, the ring travelers extending from the one running in the groove Separate the cord, which then runs via a deflection guide 77 to a strap transport shaft 78, which is driven by a motor 79 flanged to the outside of the housing (FIG. 1). The strap drive shaft 78, which interacts with a counter pressure roller 80, is driven by the motor 79 whenever a rotor fill level initiator 81 arranged above the magazine rod 74 gives a signal that the target fill level on the magazine rod has fallen below.

Aus Fig. 9 ist am besten erkennbar, dass die Magazinstange 74 am vorderen Ende einen winklig abgebogenen Einsatzhaken 82 aufweist. Auf diesem Einsatzhaken 82 muss der am Spinnring 6 anzubringende Ringläufer 7 zunächst festgeklemmt und dann freigegeben werden. Dies geht aus den Figuren 8 und 10 hervor. Am vorderen Ende der Führungsplatte 60 ist mittels eines Gelenkzapfens 83 ein Trenn- und Festklemmelement 84 schwenkbar angelenkt. Dieses besteht aus einem zweiarmigen Hebel, von welchem der eine Hebelarm 85 am vorderen Ende eine Trenn- und Festklemmplatte 86 trägt, die den vordersten Ringläufer 7 von dem hinter diesem auf der Magazinstange befindlichen Ringläufer-Vorrat abtrennt und bis zum Erreichen der Stellung des Geräts gemäss Fig. 8 am vorderen Ende der Magazinstange 74 festklemmt, so dass der Ringläufer in der Stellung gemäss Fig. 8 über den oberen Rand des Spinnrings 6 eingehängt werden kann und dabei noch festgehalten ist. Den übrigen Ringläufer-Vorrat hält eine von unten gegen die Magazinstange 74 angedrückte Blattfeder 105 zurück. Bei der anschliessenden Rückwärtsbewegung sind die Führungsplatte 60 und der Führungskörper 70 zusammen mit der Magazinstange 74 gegen die Wirkung der zwischen diesen angeordneten Druckfeder 71 relativ zueinander bewegbar. Am Hebelarm 85 des Festklemmelements 84 ist ein als Stift nach unten sich erstreckender Anschlag 88 fest angeordnet. In einem mit dem Führungskörper 70 fest verbundenen Lagerkörper 89 ist ein weiterer Anschlag in Form einer einstellbaren Anschlagschraube 90 angeordnet. Der Schraubenkopf der Anschlagschraube 90 ist gegen einen als Distanzgeber für die Ringläuferbreite wirkenden Ringläufer 7 angeschraubt, d.h. dieser ist zwischen dem Schraubenkopf und dem Lagerkörper 89 eingeklemmt. Aus Fig. 10 ist erkennbar, dass bei festgehaltener Magazinstange 74 und relativ dazu nach hinten bewegter Führungsplatte 60 der Anschlag 88 gegen die Anschlagsschraube 90 anfährt, so dass das Trenn- und Festklemmelement 84 verschwenkt wird, wodurch der auf dem Einsatzhaken 82 sitzende Ringläufer freigegeben wird. Der zweite Hebelarm 91 des Trennelements 84 ist gegen die Wirkung einer Blattfeder 92 verschwenkt, so dass der Hebelarm 91 zwangsläufig wieder unter der Wirkung der Blattfeder 92 in die Ausgangsstellung zurückkehrt, wenn die Anschläge 88 und 90 sich wieder voneinander entfernen, wobei unter der Wirkung dieser Feder 92 die Klemmwirkung zum Festhalten eines Ringläufers gemäss den Figuren 7 und 8 zustande kommt.It can best be seen from FIG. 9 that the magazine rod 74 has an insert hook 82 bent at an angle at the front end. The ring traveler 7 to be attached to the spinning ring 6 must first be clamped on this insert hook 82 and then released. This can be seen from FIGS. 8 and 10. At the front end of the guide plate 60, a separating and clamping element 84 is pivotably articulated by means of a pivot pin 83. This consists of a two-armed lever, of which a lever arm 85 carries a separating and clamping plate 86 at the front end, which separates the foremost ring traveler 7 from the ring traveler storage located behind it on the magazine rod and until the device is in the position to be reached Fig. 8 clamps at the front end of the magazine rod 74, so that the ring traveler in the position shown in FIG. 8 can be hung over the upper edge of the spinning ring 6 and is still held. The remaining ring rotor supply is held back by a leaf spring 105 pressed against the magazine rod 74 from below. During the subsequent backward movement, the guide plate 60 and the guide body 70 together with the magazine rod 74 are relative to the action of the compression spring 71 arranged between them movable to each other. On the lever arm 85 of the clamping element 84, a stop 88 extending downward as a pin is fixedly arranged. A further stop in the form of an adjustable stop screw 90 is arranged in a bearing body 89 firmly connected to the guide body 70. The screw head of the stop screw 90 is screwed against a ring traveler 7 which acts as a spacer for the ring rotor width, ie it is clamped between the screw head and the bearing body 89. From Fig. 10 it can be seen that when the magazine rod 74 is held and the guide plate 60 moved backward relative thereto, the stop 88 moves against the stop screw 90, so that the separating and clamping element 84 is pivoted, thereby releasing the ring traveler sitting on the insert hook 82 . The second lever arm 91 of the separating element 84 is pivoted against the action of a leaf spring 92, so that the lever arm 91 inevitably returns to the starting position under the action of the leaf spring 92 when the stops 88 and 90 move away from one another again, under the action of this Spring 92 the clamping effect for holding a ring traveler according to Figures 7 and 8 comes about.

Der Stellung der Magazinstange 74 beim Beginn des Einhängens des Ringläufers gemäss Fig. 8 entspricht die Stellung gemäss Fig. 9 in Draufsicht von oben, aber ohne das Festklemmelement 84, um einen weiteren Anschlag 95 darstellen zu können, der mit dem Einsetzhaken 82 am Ende der Magazinstange 74 zusammenwirkt, um das Herunterfallen des Ringläufers von diesem Hakenende zu verhindern. Dieser als zweiarmiger Hebel ausgebildete Anschlag 95 ist mittels einer Schwenkachse 96 ebenfalls am Lagerkörper 89 schwenkbar gelagert. Der hintere Hebelarm 97 des zweiarmigen Hebels trägt einen Oeffnungsnocken 98, der bei der Rückwärtsbewegung des Führungskörpers 70 zusammen mit der Magazinstange gegen einen Oeffnungsstift 99 anfährt, welcher an einem Teil des Gehäuses 1 senkrecht nach oben stehend befestigt ist, so dass der zweiarmige Anschlaghebel 95 gegen die Wirkung einer Feder 100 verschwenkt wird und das vordere Hebelarmende von dem Einsetzhaken 82 freikommt, und der Ringläufer freigegeben wird, wie aus Fig. 11 hervorgeht, damit der eingeklinkte Ringläufer bei einer weiteren Rückwärtsbewegung des Einsetzhakens 82 nicht überdehnt wird. Mit dem Einklinken des Ringläufers und der Rückkehr des Geräts 9 in die Ausserbetriebsstellung ist der Arbeitszyklus beendet. Jede Umdrehung der Welle 10 entsprechend einem Arbeitszyklus wird durch einen in Fig. 1 und Fig. 13 schematisch dargestellten Umdrehungsinitiator 102 ermittelt, der anschliessend an die Ventile angeordnet ist und der mit einem auf der Welle 10 angeordneten und bei jeder Wellenumdrehung einmal am Initiator vorbeilaufenden Stift 103 zusammenwirkt. Die Welle 10 dient somit zum Antrieb sowie zur Steuerung aller Bewegungsabläufe der beiden in parallelen Ebenen arbeitenden Geräte 8 und 9 und zur Steuerung der am Aushebegerät 8 in Funktion tretenden Düsen.8 corresponds to the position according to FIG. 9 in plan view from above, but without the clamping element 84, in order to be able to represent a further stop 95 which is connected to the insertion hook 82 at the end of FIG Magazine rod 74 cooperates to prevent the ring traveler from falling off this hook end. This stop 95, which is designed as a two-armed lever, can also be pivoted on the bearing body 89 by means of a pivot axis 96 stored. The rear lever arm 97 of the two-armed lever carries an opening cam 98 which, when the guide body 70 moves backwards, together with the magazine rod, moves against an opening pin 99 which is fastened vertically upward on part of the housing 1, so that the two-armed stop lever 95 counteracts the action of a spring 100 is pivoted and the front end of the lever arm is released from the insertion hook 82, and the ring traveler is released, as can be seen in FIG. 11, so that the latched ring traveler is not overstretched when the insertion hook 82 is moved further backward. When the ring traveler is latched in and the device 9 returns to the non-operating position, the working cycle is ended. Each revolution of the shaft 10 in accordance with a working cycle is determined by a revolution initiator 102, which is shown schematically in FIGS. 1 and 13, which is arranged next to the valves and which has a pin arranged on the shaft 10 and passing the initiator once during each revolution of the shaft 103 interacts. The shaft 10 thus serves to drive and to control all movement sequences of the two devices 8 and 9 working in parallel planes and to control the nozzles which operate on the lifting device 8.
