Abstract

What is presented is a casing (7) for a ring-spinning or cap-spinning machine, which consists of sleeve elements (8a, 8b, 8c) pushable telescopically into one another and equipped with projecting edges (11, 12), so that a hollow-cylindrical space (25) forms between the pushed-in sleeve elements (8a, 8b, 8c). The casing (7) can consequently be brought into the pushed-in position pneumatically. <IMAGE>

Description

Die Erfindung betrifft eine Einrichtung zur Ummantelung einer Spinnvorrichtung wie beispielsweise bekannt aus DE-A-3613163. Dort ist ein Abschirmelement für einen Kops auf einer Textilmaschine beschrieben, das als zylindrische Abdeckung ausgebildet ist, welche unterhalb des Laufrings angeordnet und zusammen mit diesem auf- und abbewegbar ist. Die Abdekkung umgibt den dicken, unteren Teil des Kopses ständig, so dass von diesem keine Störungen ausgehen können. Die verkürzbare Abdeckung ist entweder in Form eines Faltenbalges oder in Form eines Teleskoprohres ausgebildet. Somit kann die Abdeckung die Bewegung der Spindelbank mitmachen.The invention relates to a device for sheathing a spinning device as known, for example, from DE-A-3613163. There, a shielding element for a cop is described on a textile machine, which is designed as a cylindrical cover, which is arranged below the race and can be moved up and down together with it. The cover constantly surrounds the thick, lower part of the cop, so that no interference can arise from it. The shortenable cover is either in the form of a bellows or in the form of a telescopic tube. The cover can therefore follow the movement of the spindle bench.

In DE-A-3400327 ist eine Glockenspinnvorrichtung beschrieben, die eine Glocke aufweist, welche mit einem geringen Luftspalt von einem stillstehenden Mantel umgeben ist. Auch die Spindel und die Spule sind von einem Mantel umgeben, dessen lichte Weite jedoch so gross ist, dass sich auch der Elektromotor in seinem Inneren auf- und abbewegen kann. Zu diesem Zweck weist der die Spindel umgebende Mantel einen seitlichen Schlitz auf, durch den der Tragarm hindurch greift. Der die Glocke umgebende Mantel und der die Spindel umgebende Mantel sind zum Zwecke der Entnahme einer vollen Spule und zum Beheben eines Fadenbruches zu öffnen, beispielsweise aufklappbar. Sie sind dazu längsgeteilt, wobei die hinteren Hälften ortsfest am Maschinengestell angeordnet sind.DE-A-3400327 describes a bell spinning device which has a bell which is surrounded by a stationary jacket with a small air gap. The spindle and the coil are also surrounded by a jacket, the clear width of which, however, is so large that the electric motor can also move up and down inside. For this purpose, the jacket surrounding the spindle has a lateral slot through which the support arm extends. The jacket surrounding the bell and the jacket surrounding the spindle are to be opened, for example, to open a full bobbin and to repair a broken thread. For this purpose, they are divided lengthways, with the rear halves being arranged in a stationary manner on the machine frame.

Die beiden vorbeschriebenen Abdeckungen haben den Nachteil, dass sie einen einfachen Zugang zu der Spinnstelle kaum ermöglichen. Dieser Zugang soll gewährleistet werden bei Fadenbrüchen oder bei anderen Manipulationshandlungen an der Spinnstelle, sprich an der Spindel oder am Läufer bei einer Ringspinnmaschine oder an der Spindel und an der Glocke bei einer Glockenspinnmaschine.The two covers described above have the disadvantage that they hardly allow easy access to the spinning station. This access should be guaranteed in the event of thread breaks or other manipulation at the spinning position, i.e. on the spindle or on the rotor of one Ring spinning machine or on the spindle and on the bell in a bell spinning machine.

Die vorliegende Erfindung stellt sich nun die Aufgabe, die Ummantelung einer Spinnvorrichtung der obengenannten Art derart zu verbessern, dass eine einfache Handhabung an der Spinnstelle ermöglicht ist. Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst.The object of the present invention is to improve the sheathing of a spinning device of the type mentioned above in such a way that simple handling at the spinning position is made possible. This object is solved by the features of claim 1.

Die Erfindung hat den wesentlichen Vorteil, dass eine ständige Abdeckung der Spinnvorrichtung vorgesehen ist und gleichzeitig mit sehr einfachen Mitteln diese Ummantelung in eine eingeschobene Position gebracht werden kann.The invention has the essential advantage that a permanent covering of the spinning device is provided and, at the same time, this casing can be brought into an inserted position with very simple means.

Um gleichzeitig den entstehenden Flug, d.h. die beim Spinnen nicht eingebundenen einzelnen Fasern, zu beseitigen, ist an der Ummantelung eine Absaugung vorgesehen. In einer weiteren vorteilhaften Ausgestaltung der Erfindung dient diese Absaugung gleichzeitig zur Abführung der Abwärme, die vom Einzelmotor der Spindel erzeugt wird.At the same time the resulting flight, i.e. To remove the individual fibers that are not bound during spinning, suction is provided on the sheathing. In a further advantageous embodiment of the invention, this suction also serves to dissipate the waste heat that is generated by the individual motor of the spindle.

Weitere Vorteile der Erfindung folgen aus der nachstehenden Beschreibung. Dort wird die Erfindung anhand eines in den Zeichnungen dargestellten Beispieles näher erläutert. Es zeigt:

Further advantages of the invention follow from the description below. There, the invention is explained in more detail using an example shown in the drawings. It shows:
Fig. 1
a casing according to the invention in a bell spinning device in the extended position,
Fig. 2
the same casing in the retracted position, and
Fig. 3
another variant of the casing according to the invention in a bell spinning device.

In den Figuren werden für dieselben Elemente jeweils dieselben Bezugszeichen verwendet.In the figures, the same reference numerals are used for the same elements.

Fig. 1 zeigt eine Glockenspinnvorrichtung mit einer Glocke 1 und einer auf- und abbewegbaren Spindel 2, die von einem Einzelmotor 3 angetrieben wird. Die Glocke 1 ist ebenfalls von einem Einzelmotor 4 angetrieben. Die Glocke 1 und der Einzelmotor 4 sind fest und unbewegbar mit dem Maschinengestell 5 verbunden. Die Spindel 2 mit ihrem Einzelmotor 3 sind auf einer mit 6 angedeuteten Spindelbank auf- und abbewegbar angeordnet. Es kann jedoch genausogut umgekehrt sein, dass die Glocken 1 auf einer Glockenbank auf- und abbewegbar sind und dass die Spindeln 2 in bezug auf die Spinnmaschine fest angeordnet sind. Eine allgemein mit 7 bezeichnete Ummantelung besteht aus einzelnen Hülsenelementen 8. Der oberste Teil 9 der Ummantelung 7 ist eine massive Abdeckung, die die Glocke mit auf einem geringen Spaltabstand umgibt. Dieser Teil 9 ist ebenfalls fest mit dem Maschinengestell 5 verbunden. Der untere Rand 10 des Teiles 9 ist nach aussen vorstehend ausgebildet. Das darunterliegende Hülsenelement 8 hat einen nach innen vorstehenden Rand 11, so dass ein geringer Abstand zwischen der äusseren Wand des Teiles 9 und der inneren Wand des Hülsenelementes 8 entsteht. Der untere Rand des Hülsenelementes 8a ist wiederum mit einem nach aussen vorstehenden Rand 12 ausgebildet. Die darunterliegenden Hülsenelemente 8b und 8c sind ähnlich ausgebildet wie das Hülsenelement 8a, wobei der Durchmesser jeweils um den oben angegebenen Abstand grösser ist. In dem dargestellten ausgezogenen Zustand liegt der nach innen vorstehenden Rand 10 oder 11 des Teiles 9 oder jeweiligen Hülsenelementes 8a, 8b, 8c auf dem nach aussen vorstehenden Rand 12 des darüberliegenden Hülsenelementes. Gerade unterhalb des oberen nach innen vorstehenden Randes 11 sind Lufteintrittslöcher 13 in der Wand der Hülsenelemente 8a, 8b und 8c vorgesehen. Die Lufteintrittsöffnung 13 des untersten Hülsenelementes 8c ist mit einer mit 14 bezeichneten Drucklufteinrichtung verbunden. Ferner ist bei jedem Hülsenelement 8a, 8b und 8c oben einen nach aussen vorstehenden Rand 15 vorgesehen, der als Anschlag für das darunterliegende Hülsenelement 8b oder 8c dient. Das unterste Hülsenelement 8c steht auf einem schematisch mit einer gerade dargestellten Auflage 16 wie mit dem oberen Rand des Einzelmotors 3 übereinstimmt. Eine Absaugung 17 ist mit einem gekrümmten Rohr 18 mit dem Inneren der Ummantelung 7 verbunden. Links oben ist am Maschinengestell 5 eine Arretierung 19 vorgesehen, die mit dem oberen nach aussen vorstehenden Rand 15 des Hülsenelementes 8c in Eingriff bringbar ist. Die Arretierung 19 besteht aus einem um einen Drehpunkt 20 drehbaren Hebelarm 21, der unten mit einem Haken 22 versehen ist. Der Hebelarm wird von einer Druckfeder 23 im Gegenuhrzeigersinn gegen einen Anschlag 24 gedreht.Fig. 1 shows a bell spinning device with a bell 1 and an up and down movable spindle 2, which is driven by a single motor 3. The bell 1 is also driven by a single motor 4. The bell 1 and the single motor 4 are fixedly and immovably connected to the machine frame 5. The spindle 2 with its single motor 3 are arranged on a spindle bench indicated by 6 up and down. However, it can just as well be reversed that the bells 1 can be moved up and down on a bell bank and that the spindles 2 are fixedly arranged with respect to the spinning machine. A sheath, generally designated 7, consists of individual sleeve elements 8. The uppermost part 9 of the sheath 7 is a solid cover which surrounds the bell with a small gap distance. This part 9 is also firmly connected to the machine frame 5. The lower edge 10 of the part 9 is projecting outwards. The underlying sleeve element 8 has an inwardly projecting edge 11, so that there is a small distance between the outer wall of the part 9 and the inner wall of the sleeve element 8. The lower edge of the sleeve element 8a is in turn formed with an outwardly projecting edge 12. The sleeve elements 8b and 8c underneath are designed similarly to the sleeve element 8a, the diameter being larger in each case by the distance specified above. In the extended state shown, the inwardly projecting edge 10 or 11 of the part 9 or the respective sleeve element 8a, 8b, 8c lies on the outwardly projecting edge 12 of the sleeve element lying above it. Air inlet holes 13 are provided in the wall of the sleeve elements 8a, 8b and 8c just below the upper inwardly projecting edge 11. The air inlet opening 13 of the lowermost sleeve element 8c is connected to a compressed air device denoted by 14. Furthermore, with each sleeve element 8a, 8b and 8c there is an outwardly projecting edge 15 which serves as a stop for the underlying sleeve element 8b or 8c. The lowermost sleeve element 8c stands schematically with one Edition 16 just shown as corresponds to the upper edge of the single motor 3. A suction 17 is connected to the inside of the casing 7 by a curved tube 18. At the top left, a lock 19 is provided on the machine frame 5, which can be brought into engagement with the upper, outwardly projecting edge 15 of the sleeve element 8c. The locking device 19 consists of a lever arm 21 which can be rotated about a pivot point 20 and which is provided with a hook 22 at the bottom. The lever arm is rotated counterclockwise by a compression spring 23 against a stop 24.

In Fig. 2 sind nun dieselben Elemente dargestellt wie in Fig. 1, wobei nun die Ummantelung in die eingeschobene Position gebracht worden ist. Dabei wird der oberen nach aussen vorstehenden Rand 15 des unteren Hülsenelementes 8c vom Haken 22 festgehalten. Wie nun aus dieser Figur ersichtlich, entsteht jeweils zwischen den eingeschobenen Hülsenelementen 8a, 8b und 8c und den Teil 9 ein hohlzylindrischer Raum 25. Wie nun die Ummantelung 7 von der ausgezogenen Position (Fig. 1) in die eingeschobene Position (Fig. 2) gebracht wird ist nachstehend näher erläutert. Mit der Druckluftvorrichtung 14 wird Druckluft in die Lufteintrittsöffnungen 13 eingeblasen, wodurch der oberen, nach innen vorstehenden Rand 11 des Hülsenelementes 8c und der unteren, nach aussen vorstehenden Rand 12 des darüberliegenden Hülsenelementes 8b auseinandergedrängt werden. Sobald das Element 8c gegen den Anschlag 15 des Hülsenelementes 8b anliegt, wird die Druckluft in die Lufteintrittsöffnung 13 des Hülsenelementes 8b hineingeblasen, und wiederholt sich der oben beschriebene Vorgang. Wenn die Ummantelung 7 in die eingeschobene Position gebracht worden ist, und die Arretierung 19 mit dem oberen Rand 15 des Hülsenelementes 8c in Eingriff steht, wird die Druckluft abgeschaltet. Um die Ummantelung 7 wieder in die ausgezogene Position zu bringen, wird eine mit einem Pfeil 26 angedeutete Kraft auf den Hebelarm 21 angewandt, so dass dieser sich in Uhrzeigersinn dreht und die Hülsenelemente 8a, 8b und 8c nach unten fallen. Die Arretierung kann jedoch auch für alle Hülsenelemente der Spinnstellen der gesamten Spinnmaschine vorgesehen sein, wobei eine Lichtschranke überprüft, ob alle Ummantelungen 7 in die eingeschobene Position gebracht worden sind. Diese Arretierung besteht dann beispielsweise aus einem viereckigen Längsträger, der sich längs der ganzen Maschine erstreckt und sich mehr oder weniger in horizontaler Richtung bewegen lässt, z.B. auf einer Kreisbahn.In Fig. 2, the same elements are now shown as in Fig. 1, with the casing now being brought into the inserted position. The upper outwardly projecting edge 15 of the lower sleeve element 8c is held by the hook 22. As can now be seen from this figure, a hollow cylindrical space 25 is formed between the inserted sleeve elements 8a, 8b and 8c and the part 9. Like the casing 7 from the extended position (FIG. 1) to the inserted position (FIG. 2) is brought is explained in more detail below. Compressed air is blown into the air inlet openings 13 with the compressed air device 14, as a result of which the upper, inwardly projecting edge 11 of the sleeve element 8c and the lower, outwardly projecting edge 12 of the overlying sleeve element 8b are pushed apart. As soon as the element 8c bears against the stop 15 of the sleeve element 8b, the compressed air is blown into the air inlet opening 13 of the sleeve element 8b, and the process described above is repeated. When the casing 7 has been brought into the inserted position and the locking device 19 engages with the upper edge 15 of the sleeve element 8c, the compressed air is switched off. In order to bring the casing 7 back into the extended position, a force indicated by an arrow 26 is applied to the lever arm 21, so that it rotates clockwise and the sleeve elements 8a, 8b and 8c downwards fall. However, the locking can also be provided for all sleeve elements of the spinning positions of the entire spinning machine, with a light barrier checking whether all the sheathings 7 have been brought into the inserted position. This locking device then consists, for example, of a square longitudinal member which extends along the entire machine and can be moved more or less in the horizontal direction, for example on a circular path.

In Fig. 3 ist nun eine Variante der erfindungsgemässen Ummantelung 7 dargestellt, wobei nunmehr die Hülsenelemente 8a, 8b und 8c nach unten mit einem geringeren Durchmesser ausgebildet sind. Dies hat den Vorteil, dass der Druckluftanschluss ortsfest ist und nicht wie in dem vorgehenden Beispiel beweglich ausgestaltet sein muss. Die Ummantelung 7 ist oben mit einem becherartigen Element 27 zum Maschinengestell 5 abgeschlossen. Ferner ist unterhalb des Einzelmotors 4 ein sich nach unten konisch erweiterten Ring 28 angeordnet, der die Unterseite der Glocke teilweise umfasst. Die Absaugung 17 ist oben am Becherelement 27 mit dem Inneren der Ummantelung 7 verbunden. Der obere Rand 11' der Hülsenelemente 8a', 8b', 8c' ist in diesem Fall nach aussen vorstehend, und der untere Rand 12' nach innen vorstehend. Das Einschieben der Ummantelung funktioniert in derselben Art wie vorhin. In der Auflage 16 ist eine ringförmige Oeffnung 29 im Bereich des Einzelmotors 3 der Spindel 2 vorgesehen, so dass sich die Abwärme - mit einem Pfeil 30 dargestellt - von der Absaugung 17 erfassen lässt. Bei der Ausführungsform nach Fig. 3 ist in ähnlicher Weise wie vorhin eine Arretierung vorgesehen, die der Uebersichtlichkeit halber weggelassen wurde.3 shows a variant of the casing 7 according to the invention, the sleeve elements 8a, 8b and 8c now being designed with a smaller diameter downwards. This has the advantage that the compressed air connection is stationary and does not have to be designed to be movable as in the previous example. The casing 7 is closed at the top with a cup-like element 27 to the machine frame 5. Furthermore, a ring 28, which extends conically downwards and partially encompasses the underside of the bell, is arranged below the individual motor 4. The suction 17 is connected to the inside of the casing 7 at the top of the cup element 27. The upper edge 11 'of the sleeve elements 8a', 8b ', 8c' in this case protrudes outwards and the lower edge 12 'protrudes inwards. The insertion of the casing works in the same way as before. In the support 16, an annular opening 29 is provided in the area of the individual motor 3 of the spindle 2, so that the waste heat - represented by an arrow 30 - can be captured by the suction 17. In the embodiment according to FIG. 3, a lock is provided in a similar manner as before, which has been omitted for the sake of clarity.

Es versteht sich, dass die hülsenartigen Elemente 8a, 8b und 8c nicht bloss einen Kreiszylinder bilden, sondern auch andere zylindrische Formen annehmen können. Weiter ist es selbstverständlich, dass für die Hülsenelemente ein Leichtmetall wie Aluminium oder Kunststoff verwendet wird.It goes without saying that the sleeve-like elements 8a, 8b and 8c do not merely form a circular cylinder, but can also assume other cylindrical shapes. Furthermore, it goes without saying that a light metal such as aluminum or plastic is used for the sleeve elements.
