Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Aufsetzen von Hülsen auf ein Transportband einer Ringspinn- oder Ringzwirnmaschine, bei welcher das Band mit zum Positionieren der Hülsen dienenden Zapfen versehen ist und das Zuführen der Hülsen zum Band an einer festen Aufsetzstelle stattfindet.The present invention relates to a device for placing sleeves on a conveyor belt of a ring spinning or ring twisting machine, in which the belt is provided with pins which serve to position the sleeves and the feeding of the sleeves to the belt takes place at a fixed placement point.

Bei Ringspinn- oder Ringzwirnmaschinen wird zum Aufstecken der Hülsen auf die Spindeln eine Vielzahl von sich auf einem Transportband befindlichen Hülseh gleichzeitig erfasst und werden daraufhin diese Hülsen ebenfalls gleichzeitig auf die Spindeln aufgesteckt. Es ist dabei wichtig, dass die Hülsen auf dem Transportband genau positioniert sind. Eine nicht vollständig auf ihren Zapfen aufgesteckte Hülse kann beim Erfassen durch den Greiferbalken zerstört werden. Unter Umständen kann auch der Greiferbalken verbogen oder das Transportband beschädigt werden. Ein fehlerhaftes Aufstecken der Hülsen wird im allgemeinen durch beschädigte Hülsen, insbesondere durch beschädigte Hülsenfüsse, verursacht. Es ist deshalb wichtig, dass beschädigte Hülsen aus dem Arbeitsprozess der Maschinen entfernt werden.In the case of ring spinning or ring twisting machines, a plurality of sleeves located on a conveyor belt are simultaneously gripped to place the sleeves on the spindles, and these sleeves are then also simultaneously attached to the spindles. It is important that the sleeves are positioned exactly on the conveyor belt. A sleeve that is not fully attached to its pin can be destroyed by the gripper bar when it is gripped. Under certain circumstances, the gripper bar can be bent or the conveyor belt can be damaged. An incorrect insertion of the sleeves is generally caused by damaged sleeves, in particular damaged sleeve feet. It is therefore important that damaged sleeves are removed from the working process of the machines.

Aus der deutchen offenlegungschrift 30 26 075 ist eine Spulenwechselvorrichtung an Spinnmaschinen bekannt, welche u.a. mit einem Transportband mit senkrechten Aufnahmedornen für Hülsen zu deren Transport von einem Vorratsbehälter zur Spulenwechselvorrichtung und mit einer Abfühlvorrichtung zum Feststellen von fehlenden und fehlerhaft auf den Aufnahmedornen aufsitzenden Hülsen, ausgerüstet ist. Das Aufsetzen der Hülsen auf die Zapfen erfolgt an einer festen Aufsetzstelle.A spool changing device on spinning machines is known from German Offenlegungsschrift 30 26 075, which among other things. equipped with a conveyor belt with vertical mandrels for cores for their transport from a storage container to the bobbin changing device and with a sensing device for detecting missing and incorrectly seated cores on the mandrels. The sleeves are placed on the pins at a fixed location.

Diese Abfühlvorrichtung übt jedoch eine reine Ueberwachungsfunktion aus, die darin besteht, dass optische und akustische Signale gegeben werden oder das Transportband mit den Hülsen angehalten wird falls eine Hülse nicht korrekt auf den entsprechenden Aufnahmedorn aufgesteckt ist. Die Entfernung der fehlerhaft aufgesetzten Hülse muss jedoch von Hand durch das Bedienungspersonal besorgt werden, so dass eine derartige übernachungseinrichtung die ständige Interventionsbereitschaft des Bedienungspersonals erforderlich macht.However, this sensing device performs a purely monitoring function, which consists in that optical and acoustic signals are given or the conveyor belt with the sleeves is stopped if a sleeve is not correctly fitted onto the corresponding holding mandrel. The removal of the incorrectly placed sleeve must, however, be carried out manually by the operating personnel, so that such an overnight device requires the constant willingness of the operating personnel to intervene.

Gemäss vorliegender Erfindung soll unter Vermeidung der obenerwähnten Nachteile ein selbsttätiges Entfernen von beschädigten Hülsen aus dem Arbeitsprozess erreicht werden. Die Erfindung ist dadurch gekennzeichnet, dass zum Auswerfen von unvollständig über einen Zapfen gestülpten Hülsen die Vorrichtung einen horizontal angeordneten Stab aufweist, welcher aus seiner horizontalen Ausgangslage heraus um eine senkrecht zu seiner Längsrichtung angeordnete horizontale Schwenkachse schwenkbar und dabei einer ihn in diese Ausgangslage zurücktreibenden Federkraft ausgesetzt ist, und dass die Schwenkachse und damit der Stab an einer in bezug auf die Bewegung des Transportbandes der Aufsetzstelle nachfolgend angeordneten Kontrollstelle auf- und abwärts bewegbar ist und der Stab bei der Abwärtsbewegung mit seinem Endteil, das sich über dem Hülsenkopf der jeweils an der Kontrollstelle befindlichen Hülse befindet, derart bewegbar ist, dass bei nicht vollständig über einen Zapfen gestülpten, also höher stehenden Hülsen deren Auswerfen durch den sich abwärts bewegenden Stab unter Verschwenken desselben zu einem spitzen Winkel mit der Hülse bewirkt wird.According to the present invention, the automatic removal of damaged sleeves from the working process is to be achieved while avoiding the disadvantages mentioned above. The invention is characterized in that for ejecting sleeves which are incompletely put over a pin, the device has a horizontally arranged rod which can be swiveled out of its horizontal starting position about a horizontal pivot axis arranged perpendicular to its longitudinal direction and thereby subjected to a spring force driving it back into this starting position and that the pivot axis and thus the rod can be moved up and down at a control point arranged downstream with respect to the movement of the conveyor belt of the touchdown point and the rod during the downward movement with its end part, which is located above the sleeve head of the respective control point located sleeve is movable in such a way that in the case of sleeves that are not completely slipped over a pin, that is to say higher-standing sleeves, the sleeve is ejected by the rod moving downward while pivoting it to an acute angle with the sleeve.

Die erfindungsgemässe Vorrichtung besitzt somit den Vorteil der Einfachheit und damit grosser Zuverlässigkeit. Sie vermittelt eine automatische Sortierung beschädigter Hülsen von den übrigen Hülsen, was im Spinnereibetrieb Einsparungen bringt.The device according to the invention thus has the advantage of simplicity and thus great reliability. It provides an automatic sorting of damaged tubes from the remaining tubes, which brings savings in the spinning mill.

Im folgenden sei die Erfindung anhand eines Ausführungsbeispiels und der Zeichnung näher erläutert. In der letzteren ist

  • Fig. 1 ein Querschnitt einer Vorrichtung zum Aufsetzen von Hülsen auf ein Transportband und
  • Fig. 2 eine Seitenansicht gemäss der Linie II - 11 der Fig. 1 eines Beispiels mit einer erfindungsgemässen Anordnung.
The invention will be explained in more detail below using an exemplary embodiment and the drawing. In the latter is
  • Fig. 1 shows a cross section of a device for placing sleeves on a conveyor belt and
  • Fig. 2 is a side view along the line II - 11 of Fig. 1 of an example with an arrangement according to the invention.

In beiden Figuren sind gleiche Teile mit gleichen Bezugszeichen versehen.In both figures, the same parts are provided with the same reference symbols.

In einem Behälter 11 befindet sich ein Vorrat von Hülsen 12. Eine Fördereinrichtung umfasst zwei Walzen 13, welche mit Mulden 14 versehen sind. über die Walzen 13 läuft ein mit muldenförmigen Taschen 15 ausgestattetes Förderband 16. Der Antrieb erfolgt mittels eines Motors 17.In a container 11 there is a supply of sleeves 12. A conveying device comprises two rollers 13, which are provided with troughs 14. A conveyor belt 16 equipped with trough-shaped pockets 15 runs over the rollers 13. The drive takes place by means of a motor 17.

Auf einem Transportband 19 für Hülsen 12 sind in vorgegebenen Abständen voneinander Zapfen 20 angebracht.Pins 20 are attached to a conveyor belt 19 for sleeves 12 at predetermined distances from one another.

Auf die letzteren werden die Hülsen 12 aufgesetzt. Der gegenseitige Abstand zweier benachbarter Zapfen 20 ist gleich der Spindelteilung, d.h. gleich dem Abstand benachbarter Spindeln auf der zugehörigen Spinn- bzw. Zwirnmaschine. Mittels eines Tisches 21 werden die aufzusetzenden Hülsen 12 einzeln vom Förderband 16 abgehoben. Ein Stift 22 dient zum Lenken der in einen Fallkanal 23 fallenden Mülsen 12. Das Transportband 19 wird von einem Antrieb 24 angetrieben.The sleeves 12 are placed on the latter. The mutual distance between two adjacent pins 20 is equal to the spindle pitch, i.e. equal to the distance between adjacent spindles on the associated spinning or twisting machine. The sleeves 12 to be placed are individually lifted off the conveyor belt 16 by means of a table 21. A pin 22 serves to steer the sleeves 12 falling into a drop channel 23. The conveyor belt 19 is driven by a drive 24.

Der Fallkanal befindet sich am Ort der Aufsetzstelle, an welcher das Aufsetzen der Hülsen 12 auf das Band 19 stattfindet. Gemäss der Erfindung ist zusätzlich eine Kontrollstelle vorgesehen, an welcher nicht vollständig auf das Band 19 bzw. auf einen Zapfen 20 aufgesetzte Hülsen 12 ausgeworfen werden. In Fig. 1 befindet sich die Kontrollstelle am Ort der mittleren der drei sich über dem Band 19 befindlichen Hülsen 12. Pfeile 18 geben die Richtung der Bewegungen an.The drop channel is located at the location of the placement point at which the sleeves 12 are placed on the band 19. According to the invention, a control point is additionally provided at which sleeves 12 which are not completely ejected onto the band 19 or onto a pin 20 are ejected. In Fig. 1, the control point is at the location of the middle of the three sleeves 12 located above the band 19. Arrows 18 indicate the direction of the movements.

Die Fig. 2 ist in einem grösseren Masstab als die Fig. 1 gezeichnet. Sie zeigt wiederum eineFIG. 2 is drawn on a larger scale than FIG. 1. It shows one again

Hülse 12, das Transportband 19 und Zapfen 20. Dabei ist angenommen, dass die Hülse 12 an ihrer Fusspartie eingedrückt, d.h. beschädigt sei und nicht ordnungsgemäss auf ihrem Zapfen 20 aufgesetzt sei, wie dies auch in Fig. 1 gezeichnet ist. Ein Stab 25 ist um eine Schwenkachse 26 schwenkbar. Die letztere ist auf einer Stange 27 gelagert. Da die letztere auf- und abwärts bewegbar ist, so ist dies auch für den Stab 25 der Fall. Die Stange 27 ist im gezeigten Beispiel mittels eines in einem Zylinder 28 bewegbaren Kolbens 29 bewegbar. Mittels einer Zugfeder 30 ist der Stab 25 vorgespannt. In seiner Ruhe- oder Ausgangslage liegt er horizontal und an einem Anschlag 31 an. Der Anschlag 31 ist mit der Stange 27 fest. Um ein freies Schwenken des Stabes um die Achse 26 zu ermöglichen, ist er mit einer strichliert gezeichneten Oeffnung 32 versehen.Sleeve 12, the conveyor belt 19 and pin 20. It is assumed that the sleeve 12 is pressed in at its base, i.e. is damaged and is not properly placed on its pin 20, as is also shown in Fig. 1. A rod 25 is pivotable about a pivot axis 26. The latter is mounted on a rod 27. Since the latter can be moved up and down, this is also the case for the rod 25. In the example shown, the rod 27 can be moved by means of a piston 29 movable in a cylinder 28. The rod 25 is prestressed by means of a tension spring 30. In its rest or starting position, it lies horizontally and against a stop 31. The stop 31 is fixed to the rod 27. In order to enable the rod to pivot freely about the axis 26, it is provided with an opening 32 drawn in broken lines.

Zum Aufsetzen der Hülsen 12 auf das Transportband 19 wird dieses durch den Antrieb 24 und wird das Förderband 16 durch den Motor 17 in Betrieb gesetzt. Die auf den Tisch 21 gelangenden Hülsen 12 rollen gegen den Stift 22 und werden durch diesen veranlasst, mit dem Hülsenfuss nach unten gerichtet durch den Fallkanal 23 zu fallen. Das Förderband 16 und das Transportband 19 sind in der Weise synchronisiert, dass jede herunterfallende Hülse 12 auf einen Zapfen 20 auftrifft. Im gezeigten Beispiel liegt eine Arbeitsweise vor, gemäss welcher sich das Band 19 schrittweise bewegt. Dabei befindet sich während den Stillständen des Bandes 19 zwischen den einzelnen Schritten jeweils ein Zapfen 20 an der Aufsetzstelle, d.h. unterhalb des Fallkanals 23. Es ist aus Fig. 1 ersichtlich, dass, da der Abstand benachbarter Zapfen der Spindelteilung der Maschine gleich ist, die Kontrollstelle um eine Distanz von der Aufsetzstelle entfernt ist, welche der Spindelteilung gleich ist. Sie kann aber auch dem zwei- oder dreifachen der Spindelteilung, d.h. einem ganzzahligen Vielfachen derselben, gleich sein.To place the sleeves 12 on the conveyor belt 19, this is driven by the drive 24 and the conveyor belt 16 by the motor 17. The sleeves 12 coming onto the table 21 roll against the pin 22 and are caused by this to fall through the drop channel 23 with the sleeve foot pointing downward. The conveyor belt 16 and the conveyor belt 19 are synchronized in such a way that each falling sleeve 12 strikes a pin 20. In the example shown there is a mode of operation according to which the belt 19 moves step by step. During the standstill of the belt 19, there is a pin 20 at each point of contact between the individual steps, i.e. underneath the drop channel 23. It can be seen from FIG. 1 that, since the distance between adjacent pins of the spindle division of the machine is the same, the control point is a distance from the placement point which is the same as the spindle division. But it can also be two or three times the spindle pitch, i.e. an integer multiple of the same.

Während des Stillstandes des Transportbandes 19 wird der Kolben 29, mit diesem die Stange 27 und damit auch der Stab 25 nach unten bewegt. Diese Bewegung erfolgt um mindestens eine solche Strecke, bei welcher der in Fig. 2 linke Endteil des Stabes 25 eine ordnungsgemäss auf dem Band 19 aufgesetzte Hülse 12 am Hülsenkopf mindestens noch berührt. Eine ordnungsgemäss aufgesetzte Hülse 12 ist eine solche, welche vollständig über ihren Zapfen 20 gestülpt ist.While the conveyor belt 19 is at a standstill, the piston 29, with it the rod 27 and thus also the rod 25, is moved downward. This movement takes place by at least such a distance in which the left end part of the rod 25 in FIG. 2 at least still touches a sleeve 12 on the sleeve head which is properly placed on the band 19. A properly placed sleeve 12 is one that is completely slipped over its pin 20.

In Fig. 2 ist eine Hülse 12 gezeigt, deren Fuss eingedrückt ist und welche sich nicht in einer, einer korrekt aufgesteckten Hülse entsprechenden Position befindet. In diesem Fall drückt der Stab 25 schon bei Beginn seiner Abwärtsbewegungen gegen den Kopf der Hülse 22. Da die letztere am Zapfen 20 anstösst, wird der Stab 25 bei der gezeigten Anordnung im Uhrzeigersinn um seine Achse 26 gedreht und bildet dabei mit der Hülse 12 einen spitzen Winkel a, wie dies strichliert angedeutet ist. Dadurch wird der Hülsenkopf in Fig. 2 nach links weggedrückt und damit die Hülse 12 ausgeworfen.2 shows a sleeve 12, the foot of which is pressed in and which is not in a position corresponding to a correctly fitted sleeve. In this case, the rod 25 presses against the head of the sleeve 22 already at the beginning of its downward movements. Since the latter abuts on the pin 20, the rod 25 is rotated clockwise about its axis 26 in the arrangement shown and thereby forms one with the sleeve 12 acute angle a, as this is indicated by dashed lines. As a result, the sleeve head is pushed away to the left in FIG. 2 and the sleeve 12 is thus ejected.

Es kann vorkommen, dass die Beschädigung der Hülse 12 nur unbedeutend ist, so dass diese beim beschriebenen Vorgang nicht ausgeworfen, sondern durch den Stab 25 in eine korrekt auf dem Zapfen 20 aufsitzende Position gedrückt wird. In diesem Fall ist eine korrekte Wegnahme dieser Hülse beim Aufsetzen derselben auf die Spindeln gewährleistet. Ein solches nachträgliches Andrücken der Hülsen 12 in ihre ordnungsgemäss aufgesetzte Lage ist erwünscht, da dadurch die Genauigkeit der Positionierung der Hülsen 12 verbessert wird. Diese Arbeitsweise stellt somit einen weiteren Vorteil vorliegender Erfindung dar.It can happen that the damage to the sleeve 12 is only insignificant, so that it is not ejected in the process described, but rather is pressed by the rod 25 into a position correctly seated on the pin 20. In this case, correct removal of this sleeve is ensured when the same is placed on the spindles. Such a subsequent pressing of the sleeves 12 into their correctly placed position is desirable, since this improves the accuracy of the positioning of the sleeves 12. This mode of operation thus represents a further advantage of the present invention.

Der spitze Winkel a zwischen dem Stab 25 und der Längsachse einer ordnungsgemäss aufgesteckten Hülse 12 hängt vom gegenseitigen Abstand der Schwenkachse 26 von der Hülsenlängsachse 33 der sich jeweils an der Kontrollstelle befindlichen Hülse 12 ab; je näher diese beieinander sind, um so grösser wird, bei konstant bleibender Grösse der Abwärtsbewegung des Stabes 25, der Winkel a. Der Winkel a kann in der Praxis über 45° betragen. Ein minimaler Wert für ein sicheres Auswerfen bei bequemen Dimensionen der das Auswerfen bewirkenden Teile liegt bei ungefähr 25°.The acute angle a between the rod 25 and the longitudinal axis of a properly attached sleeve 12 depends on the mutual distance of the pivot axis 26 from the sleeve longitudinal axis 33 of the sleeve 12 located at the control point; the closer they are to each other, the greater the size of the downward movement of the rod 25, the angle a. In practice, the angle a can be over 45 °. A minimum value for a safe ejection with comfortable dimensions of the parts causing the ejection is approximately 25 °.
