Abstract

Die Maschine besitzt eine Reihe von drehbaren Spindeln (3), denen je ein um die Spindelachse drehbares, glockenförmiges Fadenführungsorgan (7) zugeordnet ist. Ein erster Antriebsriemen (5) dient zum Drehen der Spindeln (3). Ein zweiter Riemen (12) liegt an auf den Fadenführungsorganen (7) angeordneten Wirteln (11) an. Eine Andrückeinrichtung (13, 14, 15) drückt den zweiten Riemen (12) im Betrieb mit einer einstellbaren Kraft gegen die Wirtel (11), so dass der Riemen (12) durch Reibung eine kleine Bremskraft auf die schneller als der Riemen (12) laufenden Wirtel (11) ausübt. Die Andrückeinrichtung (13, 14, 15) ist umschaltbar, um den zweiten Riemen (12) mit einer wesentlich grösseren Kraft gegen die Wirtel (11) zu drücken. Beim Abstellen der Spinnmaschine wird die Andrückeinrichtung (13, 14, 15) umgeschaltet, so dass der sich verlangsamende zweite Riemen (12) eine wesentlich.grössere Reibungskraft auf die Wirtel (11) ausübt und die Fadenführungsorgane (7) rasch mit abbremst.The machine has a series of rotatable spindles (3), each of which is assigned a bell-shaped thread guide member (7) which can be rotated about the spindle axis. A first drive belt (5) is used to turn the spindles (3). A second belt (12) bears against whorls (11) arranged on the thread guide members (7). A pressure device (13, 14, 15) presses the second belt (12) during operation with an adjustable force against the whorls (11), so that the belt (12) applies a small braking force to the faster than the belt (12) due to friction. exercising running whorls (11). The pressing device (13, 14, 15) can be switched over in order to press the second belt (12) against the eddies (11) with a substantially greater force. When the spinning machine is switched off, the pressing device (13, 14, 15) is switched over, so that the slowing down second belt (12) exerts a substantially greater frictional force on the whorls (11) and the thread guiding elements (7) are also braked quickly.

Description

Die Erfindung bezieht sich auf eine Glocken­spinnmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a bell spinning machine according to the preamble of patent claim 1.

Glockenspinnmaschinen mit angetriebenen Spindeln und um die Spindelachsen drehbaren, glockenförmigen Fa­denführungsorganen sind seit langer Zeit bekannt. Die drehbaren Fadenführungsorgane benötigen in solchen Ma­schinen im Prinzip keinen eigenen Antrieb, sondern kön­nen von dem Faden, der durch eine Oeffnung beim freien Rand des Fadenführungsorgans hindurchtritt und auf die auf der Spindel sitzende Spule aufgewickelt wird, mit­geschleppt werden, ähnlich wie der Läufer in einer Ringspinnmaschine.Bell spinning machines with driven spindles and bell-shaped thread guide members which can be rotated about the spindle axes have been known for a long time. In such machines, the rotatable thread guide members in principle do not require their own drive, but can be dragged along by the thread that passes through an opening at the free edge of the thread guide member and is wound onto the spool seated on the spindle, similar to the runner in a ring spinning machine .

Häufig wird jedoch für die glockenförmigen Fa­denführungsorgane trotzdem ein Hilfsantrieb vorgesehen, der zunächst einen schnelleren Anlauf der Maschine (Be­schleunigung des relativ trägen Fadenführungsorgans) ermöglicht und der gegebenenfalls auch im Betrieb beim Ueberwinden der Reibung mithelfen kann. Damit sich im Betrieb die Drehzahl des Fadenführungsorgans - bei kon­stanter Spindeldrehzahl und konstanter Fadenzulieferge­schwindigkeit - an den wachsenden Garnpackungsdurchmes­ser anpassen kann, ist in der DE-A-30 46 180 vorgeschla­gen worden, auf den Fadenführungsorganen Wirtel anzuord­nen, die mit einem Antriebsriemen in Berührung stehen und die jeweils mit dem zugehörigen Fadenführungsorgan über einen Freilauf gekuppelt sind.Often, however, an auxiliary drive is provided for the bell-shaped thread guide members, which initially enables the machine to start up faster (acceleration of the relatively sluggish thread guide member) and which can also help in overcoming the friction during operation. In order for the speed of the thread guide member to adapt to the growing yarn package diameter during constant spindle speed and thread feed speed, DE-A-30 46 180 proposes arranging whorls on the thread guide members which are in contact with a drive belt and which are each coupled to the associated thread guide member via a freewheel.

Bei solchen Maschinen ergeben sich jedoch Pro­bleme beim Abstellen. Das Fadenführungsorgan, das eine relativ grosse Trägheit hat, zeigt die Tendenz, länger weiterzudrehen als die Spindel.With such machines, however, problems arise when parking. The thread guiding member, which has a relatively large inertia, shows the tendency to continue turning longer than the spindle.

Die Aufgabe der Erfindung besteht nun darin, in einer Glockenspinnmaschine der eingangs angegebenen Art den Hilfsantrieb, der beim Anlauf der Maschine die Fadenführungsorgane antreibt, derart auszubilden, dass beim Abstellen der Maschine die Fadenführungsorgane rascher - und etwa mit der gleichen Verzögerung wie die Spindeln - abgebremst werden. Dabei soll die Möglich­keit ebenfalls gegeben sein, dass sich im Betrieb die Drehzahl der Fadenführungsorgane an die wachsenden Garnpackungsdurchmesser anpasst.The object of the invention is now, in a bell spinning machine of the type mentioned, the auxiliary drive, which when the machine starts Drives thread guide elements to be designed in such a way that when the machine is switched off, the thread guide elements are braked more quickly - and with the same delay as the spindles. It should also be possible for the speed of the thread guide members to adapt to the growing yarn package diameter during operation.

Die Aufgabe wird erfindungsgemäss mit der im kennzeichnenden Teil des Patentanspruchs 1 definierten Einrichtung gelöst.The object is achieved according to the invention with the device defined in the characterizing part of patent claim 1.

Das Spindelantriebsorgan und der Riemen werden zweckmässig von einem gemeinsamen Antrieb mit Geschwin­digkeiten angetrieben, die in einem festen Verhältnis zueinander stehen, und zwar derart, dass der Riemen im Betrieb etwas langsamer läuft als der Umfang der Wirtel auf den vom Faden mitgenommenen Fadenführungs­organen. Die Fadenführungsorgane werden dann im Betrieb durch den Riemen mittels Reibung leicht gebremst, wobei die Bremskraft von der auf den Riemen ausgeübten, ein­stellbaren Andrückkraft abhängt. Für das Abstellen der Maschine wird dann die Andrückkraft erhöht, so dass die Fadenführungsorgane trotz ihrer relativ grossen Träg­heit annähernd synchron mit dem Riemen auslaufen und zum Stillstand kommen.The spindle drive element and the belt are expediently driven by a common drive at speeds which are in a fixed relationship to one another, in such a way that the belt runs somewhat slower in operation than the circumference of the whorls on the thread guide elements entrained by the thread. The thread guide members are then slightly braked by the belt during operation by means of friction, the braking force depending on the adjustable pressing force exerted on the belt. When the machine is switched off, the pressing force is then increased, so that the thread guide members, despite their relatively large inertia, run out almost synchronously with the belt and come to a standstill.

Die Einrichtung zum Andrücken des Riemens kann in einfacher Weise mit quer zum Riemen bewegbaren An­druckrollen realisiert werden, die von einem gemeinsa­men Steuerelement bewegt werden. Das Steuerelement kann dabei zweckmässig eine parallel zum Riemen zwischen zwei Endlagen bewegbare Steuerstange sein.The device for pressing the belt can be implemented in a simple manner with pressure rollers which can be moved transversely to the belt and are moved by a common control element. The control element can expediently be a control rod that can be moved parallel to the belt between two end positions.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. ln dieser zeigen:

  • Fig. 1 schematisch eine Seitenansicht einer Glockenspinnmaschine, teilweise im Schnitt, und
  • Fig. 2 einen Horizontalschnitt nach der Linie II - II in Fig. 1.
An embodiment of the invention is explained below with reference to the drawing. ln this show:
  • Fig. 1 shows schematically a side view of a bell spinning machine, partly in section, and
  • Fig. 2 shows a horizontal section along the line II - II in Fig. 1.

Die dargestellte Glockenspinnmaschine besitzt eine an Säulen 1 vertikal verschiebbar geführte Spindel­bank 2, die eine Reihe von Spindeln 3 trägt. Die Spin­deln 3 sind je in einem an der Spindelbank 2 angeord­neten Lager 4 um eine vertikale Achse drehbar gelagert und werden von einem Antriebsorgan angetrieben, z.B. von einem Antriebsriemen 5, der an einem Wirtel 6 je­der Spindel 3 anliegt, oder stattdessen von Einzelan­triebsmotoren.The bell spinning machine shown has a spindle bank 2, which is guided vertically displaceably on columns 1 and carries a row of spindles 3. The spindles 3 are each rotatably mounted about a vertical axis in a bearing 4 arranged on the spindle bench 2 and are driven by a drive element, e.g. from a drive belt 5, which rests against a whorl 6 of each spindle 3, or instead from individual drive motors.

Jeder Spindel 3 ist ein um die Spindelachse drehbares, glockenförmiges Fadenführungsorgan 7 zuge­ordnet. Ein von einem Streckwerk kommender Faden 8 tritt von oben in das Fadenführungsorgan 7 ein, tritt dann durch eine Führungsöffnung beim unteren Rand des Fadenführungsorgans 7 hindurch und läuft zu der auf der Spindel 3 sitzenden Spule.Each spindle 3 is assigned a bell-shaped thread guide member 7 which can be rotated about the spindle axis. A thread 8 coming from a drafting system enters the thread guide member 7 from above, then passes through a guide opening at the lower edge of the thread guide member 7 and runs to the bobbin sitting on the spindle 3.

Die Fadenführungsorgane 7 sind im oben liegen­den Halsbereich derselben in Lagern 9 in einer von den Säulen 1 getragenen Konsole 10 drehbar gelagert und tragen Wirtel 11, an denen ein Riemen 12 anliegt, der von einer Andrückeinrichtung mit einer einstellbaren Kraft gegen die Wirtel 11 gedrückt wird.The thread guide members 7 are rotatably mounted in the upper neck region of the same in bearings 9 in a bracket 10 carried by the columns 1 and carry whorls 11, against which a belt 12 rests, which is pressed against the whorls 11 by a pressing device with an adjustable force.

Die Andrückeinrichtung enthält im dargestellten Ausführungsbeispiel Andruckrollen 13, die je zwischen zwei einander benachbarten Wirteln 11 an dem Riemen 12 anliegen. Eine Andruckrolle 13 genügt wie gezeichnet für Oeweils zwei Wirtel 11; es könnten aber auch mehr Andruckrollen vorhanden sein. Das Lager 14 jeder An­druckrolle 13 ist jeweils auf einem biegsamen Plätt­chen 15, d.h einem Plättchen mit einem biegsamen, elastischen Abschnitt, befestigt, dessen Ende an einer stationären Tragschiene 16 befestigt ist. In dieser Weise ist jede Andruckrolle 13 quer oder annähernd quer zum Riemen 12 bewegbar geführt.In the exemplary embodiment shown, the pressing device contains pressure rollers 13, each of which bears against the belt 12 between two adjacent whorls 11. A pressure roller 13 is sufficient as shown for Oeweils two whorls 11; but there could also be more pressure rollers. The bearing 14 of each pressure roller 13 is in each case attached to a flexible plate 15, i.e. a plate with a flexible, elastic section, the end of which is attached to a stationary mounting rail 16. In this way, each pressure roller 13 is movably guided transversely or approximately transversely to the belt 12.

Zum Bewegen der Andruckrollen 13 - und damit zur Aenderung der Kraft, mit welcher der Riemen 12 ge­gen die Wirtel 11 gedrückt wird - ist ein gemeinsames Steuerelement in Form einer parallel zum Riemen 12 ver­schiebbaren Steuerstange 17 vorgesehen. Auf der Steuer­stange 17 ist für jedes der Plättchen 15 je ein Nocken 18 montiert. Die Plättchen 15 sind zum Riemen 12 geneigt und stellen so eine zum Riemen 12 geneigte Fläche dar, und an ihren Rückseitenflächen greift je­weils einer der Nocken 18 an. Wenn die Steuerstange 17 mit den Nocken 18 in Richtung des Pfeiles P parallel zur Laufrichtung des Riemens 12 verschoben wird, werden dadurch die Andruckrollen 13 entgegen der elastischen Biegekraft der Plättchen 15 zum Riemen 12 hin bewegt und drücken denselben stärker gegen die Wirtel 11. Die Steuerstange 17 wird von einem doppeltwirkenden Zylin­der-Kolben-Aggregat 19 bewegt. Der Verschiebeweg der Steuerstange 17 ist in beiden Richtungen durch je einen einstellbaren Anschlag 20 bzw. 21 begrenzt.To move the pressure rollers 13 - and thus To change the force with which the belt 12 is pressed against the whorls 11 - a common control element in the form of a control rod 17 which can be displaced parallel to the belt 12 is provided. A cam 18 is mounted on the control rod 17 for each of the plates 15. The plates 15 are inclined to the belt 12 and thus represent a surface inclined to the belt 12, and one of the cams 18 engages on their rear surfaces. If the control rod 17 is moved with the cams 18 in the direction of arrow P parallel to the direction of travel of the belt 12, the pressure rollers 13 are thereby moved against the elastic bending force of the plate 15 towards the belt 12 and press the latter more strongly against the whorls 11. The control rod 17 is moved by a double-acting cylinder-piston unit 19. The displacement of the control rod 17 is limited in both directions by an adjustable stop 20 and 21, respectively.

Im Betrieb der Spinnmaschine werden der Spindel­antriebsriemen 5 und der Riemen 12 von einem nicht dar­gestellten Antrieb mit Geschwindigkeiten angetrieben, die in einem konstanten Verhältnis zueinander stehen, und zwar derart, dass die Lineargeschwindigkeit des Riemens 12 etwas kleiner eingestellt ist als die Tan­gentialgeschwindigkeit der Umfangsflächen der Wirtel 11, die auf den von den Fäden nachgeschleppten Fadenfüh­rungsorganen 7 sitzen. Der Riemen 12 übt daher auf die Wirtel 11 durch Reibung eine geringe Bremskraft aus. Die Grösse der Bremskraft ist abhängig von der Kraft, mit der die Andruckrollen 13 den Riemen 12 gegen die Wirtel 11 drücken. Die Steuerstange 17 steht während des Spinnens wie gezeichnet in seiner in Fig. 2 unte­ren Endlage am Endanschlag 20, so dass sich die An­druckrollen 13 nur wenig in die Bahn des Riemens 12 hineinerstrecken, d.h., nur eine kleine Druckkraft auf den Riemen 12 ausüben. Durch Verstellen des Endanschla­ ges 20, wodurch die Nocken 18 längs der geneigten Plättchen 15 in eine andere Lage kommen, kann die von den Andruckrollen 13 auf den Riemen 12 ausgeübte Druck­kraft und damit die vom Riemen 12 auf die Wirtel 11 durch Reibung ausgeübte Bremskraft geändert und an die im besonderen Fall vorliegenden Gegebenheiten, z.B. an die Art des Fadens 8, angepasst werden.In operation of the spinning machine, the spindle drive belt 5 and the belt 12 are driven by a drive, not shown, at speeds which are in constant relation to one another, in such a way that the linear speed of the belt 12 is set somewhat less than the tangential speed of the peripheral surfaces of the whorls 11, which sit on the thread guide members 7 dragged by the threads. The belt 12 therefore exerts a small braking force on the whorls 11 due to friction. The magnitude of the braking force depends on the force with which the pressure rollers 13 press the belt 12 against the whorls 11. The control rod 17 stands during the spinning as drawn in its lower end position in FIG. 2 at the end stop 20, so that the pressure rollers 13 extend only a little into the path of the belt 12, ie only exert a small compressive force on the belt 12. By adjusting the end stop ges 20, whereby the cams 18 along the inclined plate 15 come into a different position, the pressure force exerted by the pressure rollers 13 on the belt 12 and thus the braking force exerted by the belt 12 on the whorls 11 by friction and changed to the particular In the present circumstances, for example, to be adapted to the type of thread 8.

Beim Abstellen der Spinnmaschine wird mit dem Ausschalten und gegebenenfalls Abbremsen des Antriebes der Riemen 5 und 12 auch das Zylinder-Kolben-Aggregat 19 betätigt und dadurch die Steuerstange 17 ausreichend schnell in ihre andere Endlage am Endanschlag 21 ver­stellt bzw. verschoben bzw. bewegt. Dabei bewegen die Nocken 18 über die geneigten Plättchen 15 die Andruck­rollen 13 weiter zum Riemen 12 hin. Die Kraft, mit wel­cher der Riemen 12 gegen die Wirtel 11 gedrückt wird, wird dadurch so gross, dass der Riemen 12 die zum Ab­bremsen der Fadenführungsorgane 7 erforderliche Brems­kraft - durch Reibung oder sogar unter Aufhebung des Schlupfes zwischen Riemen 12 und Wirtel 11 - auf die Wirtel 11 übertragen kann.When the spinning machine is switched off, the cylinder-piston unit 19 is also actuated when the drive for the belts 5 and 12 is switched off and, if necessary, braked, and the control rod 17 is thereby adjusted, shifted or moved sufficiently quickly into its other end position at the end stop 21. The cams 18 move the pressure rollers 13 further towards the belt 12 via the inclined plates 15. The force with which the belt 12 is pressed against the whorls 11 becomes so great that the belt 12 has the braking force required to brake the thread guiding elements 7 - by friction or even by eliminating the slippage between the belt 12 and whorls 11 - on the Whorls 11 can transmit.

Die Verwendung des gemeinsamen Steuerelementes 17 zum Bewegen der Andruckrollen 13 ist zweckmässig. Die Uebertragung der Bewegung vom Steuerelement 17 auf die Andruckrollen 13 könnte aber natürlich auch anders als anhand der Zeichnung beschrieben erfolgen. Bei­spielsweise könnte jede Andruckrolle 13 von einem Arm je eines in der Tragschiene 16 schwenkbar gelagerten zweiarmigen Hebels getragen sein, wobei die anderen Arme dieser Hebel an einer parallel zum Riemen 12 be­wegbaren Steuerstange angelenkt wären. Oder die Lager 14 der Andruckrollen 13 könnten in der Tragschiene 16 quer zum Riemen 12 verschiebbar geführt sein und sich an je einer auf der verschiebbaren Steuerstange 17 angeordneten, zum Riemen 12 geneigten Rampe ab­stützen. Auch andersartig bewegbare gemeinsame Steuer­ elemente zum Bewegen von quer zum Riemen 12 bewegbar geführten Andruckrollen sind denkbar. Die Nocken 18 können auch eine Keilform haben. Der Riemen 12 kann na­türlich auch nur für das Anfahren und das Abstellen der Maschine verwendet werden.The use of the common control element 17 for moving the pressure rollers 13 is expedient. The transmission of the movement from the control element 17 to the pressure rollers 13 could, of course, also take place differently than described with reference to the drawing. For example, each pressure roller 13 could be carried by one arm each of a two-armed lever pivotally mounted in the mounting rail 16, the other arms of these levers being articulated on a control rod which can be moved parallel to the belt 12. Or the bearings 14 of the pressure rollers 13 could be guided displaceably in the carrier rail 16 transversely to the belt 12 and supported on a ramp arranged on the displaceable control rod 17 and inclined to the belt 12. Also differently movable joint tax elements for moving pressure rollers which are movably guided transversely to the belt 12 are conceivable. The cams 18 can also have a wedge shape. The belt 12 can of course also only be used for starting and stopping the machine.
