Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer automatischen Spulmaschine nach dem Oberbegriff des ersten Anspruches.The invention relates to a method for operating an automatic winding machine according to the preamble of the first claim.

Automatische Spulmaschinen weisen auch ein automatisches Kops- und Hülsentransportsystem auf, weiches mehrere Transportschleifen für Kopse und Hülsen besitzen kann. Derartige Transportsysteme weisen in vielen Fällen auch eine direkte Verbindung zum Transportsystem der Spinnmaschine auf, wobei an der Schnittstelle Kopse und Hülsen ausgetauscht werden. Ein derartiges Transportsystem ist zum Beispiel aus der DE 39 19 542 A 1 bekannt. In dieser Schrift ist jedoch nicht dargestellt, wie bei einem Partiewechsel zu verfahren ist.Automatic winding machines also have an automatic bobbin and tube transport system, which can have several transport loops for bobbins and tubes. In many cases, such transport systems also have a direct connection to the transport system of the spinning machine, with copes and sleeves being exchanged at the interface. Such a transport system is known for example from DE 39 19 542 A1. However, this document does not show how to proceed when changing lots.

Aufgabe der Erfindung ist es, ein Verfahren zum Betreiben einer automatischen Spulmaschine zu schaffen, welches beim Partiewechsel anwendbar ist.The object of the invention is to provide a method for operating an automatic winding machine which can be used when changing lots.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des ersten Anspruches gelöst.This object is achieved by the characterizing features of the first claim.

Bei Auslauf einer Partie sollen die zugeführten Kopse aufgebraucht werden, während der Spinnmaschine keine Hülsen mehr zugeführt werden sollen. Die dieser Partie zugehörigen Hülsen müssen demzufolge gespeichert werden. Die erfindungsgemäße Lösung läßt die Speicherung der Hülsen zu, ohne daß zusätzliche Speicherkapazität erforderlich ist.When a batch runs out, the supplied cops are to be used up, while no more sleeves are to be fed to the spinning machine. The sleeves belonging to this lot must therefore be saved. The Solution according to the invention allows the sleeves to be stored without requiring additional storage capacity.

Die Erfindung ist durch die kennzeichnenden Merkmale des Anspruchs 2 vorteilhaft weitergebildet.The invention is advantageously further developed by the characterizing features of claim 2.

Wenn zwischen einem Transportweg der Spinnmaschine und dem benachbarten Transportweg der Spulmaschine leere Hülsen gegen frische Kopse ausgetauscht werden, ist dieser Prozeß beendet, wenn nach Auslauf der Partie keine frischen Kopse von der Spinnmaschine mehr ankommen. Deshalb sollen dieser Transportstrecke auch keine leeren Hülsen mehr zugeführt werden. Das kann auf einfache Weise dadurch geschehen, daß die Leerhülsen vor dem Transportweg, der für den Austausch vorgesehen ist, abgezweigt und dem Kopszuführweg wieder zugeleitet werden. Um dabei durch die leeren Hülsen nicht unnötige Wechselschaltungen an den Spulstellen herbeizuführen, ist es von Vorteil, die Hülsen an Abzweigungen zu den Spulstellen mittels Sensoren zu detektieren und an diesen Abzweigungen vorbeizuleiten. Diese Hülsen gelangen dann um das Ende der Spulmaschine herum auf den Hülsenrückführweg, in den die durch die Spulstellen verlaufenden Transportwege münden. Ein derartiger, um das Ende der Spulmaschine herum verlaufender Weg ist zum Beispiel in der gattungsbildenden DE 39 19 542 A 1 beschrieben. Dabei ist es auch von Vorteil, die Kopse und Hülsen senkrecht aufgesteckt auf Aufsteckdorne von Caddy's zu transportieren, die auf Transportbändern aufliegen, von denen sie durch Reibschluß mitgenommen werden. Die Caddy's werden dabei innerhalb von Transportkanälen geführt. Derartige Transportsysteme sind bereits seit langem, zum Beispiel durch die JP-A 52-25 139 bekannt.If empty cores are exchanged for fresh cops between a transport path of the spinning machine and the neighboring transport path of the winding machine, this process is ended when no fresh cops arrive from the spinning machine after the batch has ended. For this reason, empty sleeves should no longer be fed to this transport route. This can be done in a simple manner in that the empty tubes are branched off before the transport path which is intended for the exchange and are fed back to the cop feed path. In order to avoid unnecessary change-over circuits at the winding stations through the empty sleeves, it is advantageous to detect the sleeves at branches to the winding stations by means of sensors and to guide them past these branches. These tubes then go around the end of the winding machine onto the tube return path into which the transport paths running through the winding units open. Such a path, which runs around the end of the winding machine, is described for example in the generic DE 39 19 542 A1. It is also advantageous to transport the cops and sleeves vertically on Caddy's arbors, which rest on conveyor belts, from which they are carried by friction. The caddy's are managed within transport channels. Such transport systems have long been known, for example from JP-A 52-25 139.

Die Erfindung soll nachfolgend anhand eines Ausführungsbeispieles näher erläutert werden. Die zugehörige Zeichnung zeigt ein Transportsystem einer Spulmaschine, welches aus Platzgründen in Teilfiguren 1a und 1b unterteilt wurde.The invention will be explained in more detail below using an exemplary embodiment. The associated Drawing shows a transport system of a winding machine, which was divided into partial figures 1a and 1b for reasons of space.

Die Spulmaschine 1 besitzt ein Kops- und Hülsentransportsystem mit mehreren Transportschleifen, die teilweise gemeinsame Transportwege aufweisen. Auf diesen Transportwegen werden Caddy's 4 transportiert, die Kopse beziehungsweise Hülsen tragen. Auf die Darstellung der Kopse beziehungsweise Hülsen wurde aus Übersichtsgründen verzichtet.The winding machine 1 has a bobbin and tube transport system with several transport loops, some of which have common transport paths. Caddy's 4, which carry cops or sleeves, are transported on these transport routes. The depiction of the cops or sleeves has been omitted for reasons of clarity.

Entlang der gesamten Spulmaschine 1 erstreckt sich eine Zuführbahn 2 zum Zuführen der Kopse zu den Spulstellen. Von der Zuführbahn 2 zweigen Vorbereitungsstrecken 25 ab, die durch Vorbereitungsstationen 26 bis 28 führen. Durch diese Vorbereitungsstationen 25 bis 28 kann eine stufenweise Vorbereitung der Kopse in bekannter Weise erfolgen, wie das zum Beispiel in der DE 39 19 542 A 1 beschrieben ist. Am Ende der Vorbereitungsstrecke 25 ist eine Verteilstrecke 24 vorgesehen, die die Kopse alternativ einem sogenannten Reversierband 3 oder erneut der Zuführbahn 2 zuführt. Diese Verteilstrecke 24 wird von der letzten Vorbereitungsstation 28 angesteuert, die den Kopsvorbereitungserfolg überprüft. Wurde der Kops erfolgreich vorbereitet, führt ihn die Verteilstrecke 24, die auch aus einem reversierenden Band bestehen kann, dem Reversierband 3 zu. Konnte der Kops nicht erfolgreich vorbereitet werden, wird der ihn tragende Caddy 4 der Zuführbahn 2 zugeleitet, die ihn entweder zur nächsten Vorbereitungsstrecke 25 oder um das Ende der Spulmaschine 1 über die Umleitungsstrecke 31 auf das Rückführband 22 leitet. Dieses Rückführband 22 verläuft parallel zum Zuführband 2 ebenfalls entlang der gesamten Spulmaschine. Die Verteilung der Kopse auf die verschiedenen Vorbereitungsstrecken 25 ist ebenfalls in der DE 39 19 542 A 1 beschrieben, weshalb hier nicht näher darauf eingegangen zu werden braucht.A feed path 2 for feeding the cops to the winding stations extends along the entire winding machine 1. Preparation lines 25 branch off from the feed path 2 and lead through preparation stations 26 to 28. These preparation stations 25 to 28 can be used to prepare the cops step by step in a known manner, as is described, for example, in DE 39 19 542 A1. At the end of the preparation section 25, a distribution section 24 is provided which alternatively feeds the cops to a so-called reversing belt 3 or again to the feed path 2. This distribution section 24 is controlled by the last preparation station 28, which checks the success of the cop preparation. If the cop is successfully prepared, the distribution section 24, which can also consist of a reversing belt, feeds it to the reversing belt 3. If the cop was not successfully prepared, the caddy 4 carrying it is fed to the feed path 2, which either leads it to the next preparation path 25 or around the end of the winding machine 1 via the diversion path 31 to the return belt 22. This return belt 22 also runs parallel to the feed belt 2 along the entire winding machine. The distribution of the cops on the different preparation lines 25 is also described in DE 39 19 542 A1, which is why there is no need to go into this here.

Das Reversierband 3 wird in vorgebbaren Zeitabständen in seiner Transportrichtung umgeschaltet und verteilt die zugeführten Kopse auf die durch die Spulstellen 5 führenden Transportbahnen 21. Zwischen der Spulstelle 5, das heißt der Abspulstellung des jeweiligen Kopses, und dem Reversierband 3 sind noch zwei Reservepositionen 6 für die die Kopse tragenden Caddy's 4 vorhanden. Auf dem Reversierband 3 patroullieren Gruppen 7 von Caddy's mit Kopsen, die dann in eine durch die Spulstellen führende Transportbahn 21 eintreten, wenn die hinterste Reserveposition 6 nicht besetzt ist. Einzelheiten dazu sind ebenfalls der DE 39 19 542 A 1 zu entnehmen. Dabei ist noch darauf hinzuweisen, daß aus Übersichtsgründen nur ein geringer Teil der umlaufenden Caddy's 4 dargestellt worden ist. Insbesondere müßten die Transportbahnen 21 in den meisten Fällen mit drei Caddy's besetzt sein, wie das an einer Transportbahn 21 demonstriert wird.The reversing belt 3 is switched in its transport direction at predeterminable time intervals and distributes the supplied cops to the transport paths 21 leading through the winding stations 5. Between the winding station 5, that is to say the unwinding position of the respective cop, and the reversing belt 3 there are still two reserve positions 6 for them the bobbins wearing Caddy 4. On the reversing belt 3, groups 7 of Caddy's patrol with cops, which then enter a transport path 21 leading through the winding stations when the rearmost reserve position 6 is not occupied. Details on this can also be found in DE 39 19 542 A1. It should also be pointed out that only a small part of the circulating Caddy's 4 has been shown for reasons of clarity. In particular, the transport tracks 21 would have to be occupied with three caddies in most cases, as is demonstrated on a transport track 21.

Nachfolgend sollen die Transportbahnen am Ende des Rückführbandes mit zugehörigen Bearbeitungsstationen näher beschrieben werden.The transport tracks at the end of the return belt with associated processing stations are described in more detail below.

Mit 9 ist ein sogenannter Restkops bezeichnet, der noch eine weiterverarbeitbare Restfadenmenge trägt. Dieser Restkops 9 befindet sich neben einem Restfadendetektor 33, der die noch vorhandene Fadenmenge erfaßt. Dieser Restfadendetektor steuert einen Elektromagneten 11, der auf einen an den Caddy's 4 vorhandenen Eisenring wirkt und den Caddy vom Rückführband 22 auf die Nebentransportbahn 12 umlenkt. Auf dieser Nebentransportbahn 12 gelangt der Restkops 9 dann zu einer Kegelvorbereitungseinrichtung 15, die den Fadenanfang am Kopskegel unabhängig von dessen Lage sucht und so wieder ablegt, daß er an der Spulstelle erfaßbar ist. Über die Anschlußstrecke 16 wird ein so vorbereiteter Kops dann der Zuführbahn 2 wieder zugeleitet. Die Kegelvorbereitungseinrichtung 15 besitzt jedoch ebenfalls einen Detektor, der den Vorbereitungserfolg überprüft. War der Restkops 9 nicht erfolgreich vorbereitbar, gelangt er auf den Zuführweg 17 zu einer Staustrecke 18.9 is a so-called residual cop, which still carries a quantity of remaining thread that can be processed. This residual cop 9 is located next to a residual thread detector 33, which detects the thread quantity still present. This residual thread detector controls an electromagnet 11, which acts on an iron ring present on the caddy's 4 and deflects the caddy from the return belt 22 onto the secondary transport path 12. On this secondary transport path 12, the remaining cop 9 then arrives at a cone preparation device 15, which searches for the thread start on the cop cone regardless of its position and deposits it again in such a way that it can be detected at the winding point. A cop prepared in this way is then fed back to the feed path 2 via the connecting section 16. However, the cone preparation device 15 also has one Detector that checks the preparation success. If the remaining cop 9 could not be successfully prepared, it arrives on the feed path 17 to a storage section 18.

Eine neben einem Endgestell 19 vorbeitransportierte Hülse 8 mit geringer Restfadenmenge wird ebenfalls als solche vom Restfadendetektor 33 identifiziert und der sie tragende Caddy 4 vom Elektromagneten 11 in die Nebentransportbahn 12 umgeleitet. Allerdings wird diese Hülse 8 unmittelbar anschließend erneut abgezweigt und gelangt zu einer Hülsenreinigungseinrichtung 10. An dieser Abzweigung kann ebenfalls ein Elektromagnet angeordnet sein, der vom Restfadendetektor 33 zusätzlich angesteuert wird. Auf eine Darstellung wurde aus Platzgründen verzichtet. Die gereinigte Hülse 8 gelangt dann wieder auf die Rückführbahn 20 oder nach nicht erfolgreicher Reinigung in die Speicherstrecke 18 (siehe auch hierzu DE 39 19 542 A 1). Eine von einer Spulstelle 5 ausgeworfene komplett leergespulte Hülse 36 wird auf der Rückführbahn 22 ebenfalls dem Restfadendetektor 33 zugeführt, der im normalen Spulbetrieb den Elektromagneten 11 nicht einschaltet, so daß der die Leerhülse 36 tragende Caddy auf die Transportbahn 13 gelangt, an der die Leerhülse gegen einen frischen, von der Spinnmaschine kommenden Kops ausgetauscht wird. Dieser Kops gelangt dann wieder auf die Zuführbahn 2 und in der beschriebenen Weise zu seiner Abspulstellung in der Spulmaschine.A sleeve 8 transported past next to an end frame 19 with a small amount of remaining thread is likewise identified as such by the remaining thread detector 33 and the caddy 4 carrying it is redirected by the electromagnet 11 into the secondary transport path 12. However, this sleeve 8 is immediately branched off again and arrives at a sleeve cleaning device 10. An electromagnet can also be arranged at this branch, which is additionally controlled by the residual thread detector 33. A representation has been omitted for reasons of space. The cleaned sleeve 8 then returns to the return path 20 or, after unsuccessful cleaning, into the storage path 18 (see also DE 39 19 542 A1). A completely empty spool 36 ejected from a winding unit 5 is also fed to the residual thread detector 33 on the return path 22, which does not switch on the electromagnet 11 in normal winding operation, so that the caddy carrying the empty tube 36 arrives on the transport path 13, against which the empty tube counteracts a fresh cop coming from the spinning machine is exchanged. This cop then returns to the feed path 2 and, in the manner described, to its unwinding position in the winding machine.

Ist die Partie abgelaufen und wird auf der Transportbahn 13 kein Austausch zwischen Leerhülsen und frischen Kopsen mehr durchgeführt, ist es von Vorteil, diese Transportbahn 13 stillzulegen und die Leerhülsen 36 ebenfalls an der durch den Elektromagneten 11 gebildeten Weiche in die Transportbahn 12 abzuzweigen. Die Steuerung durch den Restfadendetektor wird dann so umgeschaltet, daß er den Elektromagneten 11 ständig eingeschaltet läßt und zusätzlich nach dem Passieren einer Leerhülse 36 einen weiteren Elektromagneten 37 aktiviert, wodurch diese Leerhülse 36 über den Transportweg 14 für Leerhülsen der Zuführbahn 2 wieder zugeleitet wird. Unabhängig davon können vom Restfadendetektor 33 erkannte Restkopse 9 der Kegelvorbereitungseinrichtung 15 zugeleitet werden, indem der Restfadendetektor 33 nach der Identifikation als Restkops den Elektromagneten 37 nicht aktiviert. Auch Hülsen mit geringer Restfadenmenge werden der Hülsenputzeinrichtung 10 in der beschriebenen Weise zugeführt. Damit finden alle erforderlichen Funktionen dieser Vorrichtungen auch dann statt, wenn die Leerhülsen 36 im System zirkulieren.If the lot has expired and there is no longer an exchange between empty tubes and fresh cops on the transport path 13, it is advantageous to shut down this transport path 13 and also to branch off the empty tubes 36 into the transport path 12 at the switch formed by the electromagnet 11. The control by the residual thread detector is then switched over so that it keeps the electromagnet 11 switched on and additionally activates a further electromagnet 37 after passing through an empty sleeve 36. whereby this empty tube 36 is again fed via the transport path 14 for empty tubes to the feed path 2. Regardless of this, residual cops 9 detected by the residual thread detector 33 can be fed to the cone preparation device 15 by the residual thread detector 33 not activating the electromagnet 37 after identification as a residual cop. Even sleeves with a small amount of remaining thread are fed to the sleeve cleaning device 10 in the manner described. This means that all the necessary functions of these devices also take place when the empty sleeves 36 circulate in the system.

An den jeweiligen Abzweigungen von der Zuführbahn 2 in die Vorbereitungsstrecken 25 sind Sensoren 29 angeordnet, die ankommende Leerhülsen 36 erkennen und eine benachbarte Weiche 30 öffnen, um dem die Leerhülse 36 tragenden Caddy 4 den Weitertransport auf der Zuführbahn 2 zu ermöglichen. Dadurch wird gesichert, daß die Leerhülsen auf den für sie bestimmten Transportwegen bleiben. Unabhängig davon sind die Weichen 30 auch dafür vorgesehen, im normalen Betrieb der Spulmaschine die Kopse auf die Vorbereitungsstrecken 25 zu verteilen. Sind zum Beispiel, wie das in der Zeichnung dargestellt ist, zwei Vorbereitungsstrecken 25 vorhanden, würde die an der in Zuführrichtung der Kopse ersten Abzweigung angeordnete Weiche 30 abwechselnd jeden zweiten Kops passieren lassen. Ebenso ist es selbstverständlich möglich, jeweils nach zwei oder mehr Kopsen umzuschalten. Eine weitere Möglichkeit besteht darin, daß bei gefüllter Strecke zwischen der Zuführbahn und der ersten Vorbereitungsstation 26 der nächste ankommende Kops beziehungsweise der ihn tragende Caddy 4 durch den äußeren Rand des letzten Caddy's abgelenkt und auf der Zuführbahn 2 zur nächsten Vorbereitungsstrecke 25 weiter transportiert wird.At the respective branches from the feed path 2 into the preparation lines 25, sensors 29 are arranged, which detect incoming empty tubes 36 and open an adjacent switch 30 in order to enable the caddy 4 carrying the empty tube 36 to be transported further on the feed path 2. This ensures that the empty tubes remain on the transport routes intended for them. Irrespective of this, the switches 30 are also provided for distributing the cops over the preparation lines 25 during normal operation of the winding machine. If, for example, as shown in the drawing, there are two preparation sections 25, the switch 30 arranged on the first branch in the feed direction of the cops would alternately pass every second cop. It is of course also possible to switch over after two or more cops. Another possibility is that when the distance between the feed path and the first preparation station 26 is filled, the next arriving cop or the caddy 4 carrying it is deflected by the outer edge of the last caddy and transported on the feed path 2 to the next preparation path 25.

Der Weg der Leerhülsen ist durch Richtungspfeile 23, 32, 34 und 35 gekennzeichnet. Dieser Transportweg ist ausreichend lang, um alle Leerhülsen 36 aufzunehmen, da die Anzahl der Caddy's 4 im Transportsystem gleichbleibend ist. Auf diese Weise kann ein zusätzlicher Speicher für die Zwischenlagerung der Leerhülsen 36 bis zum Abschluß des Partiewechsels eingespart werden.The path of the empty tubes is indicated by arrows 23, 32, 34 and 35. This transport route is long enough to accommodate all empty tubes 36, since the number of caddies 4 in Transport system is constant. In this way, an additional memory for the intermediate storage of the empty tubes 36 can be saved until the end of the batch change.
