Description

Die Erfindung betrifft eine Speichereinrichtung einer Spulmaschine mit den Merkmalen des Oberbegriffs des ersten Anspruches.The invention relates to a storage device of a winding machine with the features of the preamble of the first claim.

Der Einsatz von voneinander unabhängigen Caddy's, die üblicherweise innerhalb eines in sich geschlossenen Transportsystemes zirkulieren und aufrechtstehend Spulen und Spulenhülsen transportieren, ist seit langem bekannt.The use of independent caddies, which usually circulate within a self-contained transport system and transport coils and bobbin tubes upright, has been known for a long time.

Ein derartiger Transportkreislauf für Caddy's ist zum Beispiel in der JP-A 52-25 139 beschrieben. Besonderer Vorteil ist die Vermeidung von Beschädigungen der Bewicklung der Kopse sowie auch insbesondere die Möglichkeit der individuellen Handhabung der einzelne Kopse beziehungsweise Spulenhülsen tragenden Caddy's.Such a transport cycle for caddy's is described, for example, in JP-A 52-25 139. A particular advantage is the avoidance of damage to the winding of the cops and, in particular, the possibility of individual handling of the individual cops or caddy-bearing bobbins.

Wie es bei geschlossenen Transportsystemen, die Verarbeitungseinrichtungen mit einschließen, üblich und notwendig ist, ist zur Anpassung an die schwankende Aufnahme von Kopsen in der Verarbeitungseinrichtung, bei der JP-A 52-25 139 einer Spinnmaschine, vorgesehen, in der Transportschleife eine oder mehrere Speicher vorzusehen. Dabei handelt es sich entweder um einen Leerhülsenspeicher oder um einen Kopsspeicher.As is customary and necessary in the case of closed transport systems which include processing devices, in JP-A 52-25 139 a spinning machine, one or more memories are provided in the transport loop in order to adapt to the fluctuating reception of cops in the processing device to provide. It is either an empty case memory or a head memory.

Durch die DE-A 17 60 689 ist eine gattungsgemäße Speichereinrichtung einer Spulmaschine für voneinander unabhängige Caddy's bekannt geworden. Die Caddy's zirkulieren innerhalb des Transportsystemes der Spulmaschine. Die Speichereinrichtung ist ein- und ausgangsseitig an dieses Transportsystem angeschlossen und besitzt eine Kopsaufsteckposition. Dabei werden von Hand zunächst die von der Spulmaschine kommenden Leerhülsen von den Caddy's abgezogen und in der Kopsaufsteckposition neue, abzuspulende Kopse aufgesteckt.From DE-A 17 60 689, a generic storage device of a winding machine for mutually independent caddies has become known. The caddies circulate within the transport system of the winding machine. The storage device is connected on the input and output side to this transport system and has a cop attachment position. The empty tubes coming from the winding machine are first pulled off by hand from the caddies and new heads to be unwound are put on in the bobbin winder position.

Eine ähnliche Einrichtung ist in der nicht vorveröffentlichten DE 40 29 894 A1 beschrieben. Durch diese Einrichtung ist es bekannt, daß in ein im Bodenbereich der Spulmaschine angeordnetes Transportsystem ein Speicher parallel zur Ablaufspulenhülsen und Restspulen führenden Rückführtransportstrecke angeordnet und so integriert ist, daß sich ein geschlossener Kreislauf für voneinander unabhängige Einzelträger für die Ablaufspulen ergibt. Die im Speicher angeordneten Einzelträger können mit Hilfe einer Beschickungseinrichtung mit neuen Kopsen versorgt werden. Die Beschickungseinrichtung besitzt Schachtabschnitte, die geöffnet den freien Durchgang der Ablaufspulen gestatten und geschlossen eine sichere Führung der Ablaufspulen beim Aufsetzen auf die Einzelträger bilden.A similar device is described in the unpublished DE 40 29 894 A1. By this device, it is known that in a transport system arranged in the bottom area of the winding machine, a storage device is arranged parallel to the return transport path leading the payout spool sleeves and residual spools and is integrated in such a way that there is a closed circuit for independent individual carriers for the payout spools. The individual carriers arranged in the memory can be supplied with new cops with the aid of a loading device. The loading device has shaft sections which, when opened, permit the free passage of the payout spools and, when closed, form a safe guidance of the payout spools when they are placed on the individual carriers.

Die bekannten Speichereinrichtungen besitzen nur relativ wenige Speicherplätze für die Caddy's, wodurch die Bedienungsperson in kurzen Zeitabständen an die Maschine zurückkehren muß, um neue Kopse auf die Caddy's aufzustecken und letztlich zu vermeiden, daß leere Caddy's beziehungsweise Caddy's mit Leerhülsen den Spulstellen zugeführt werden.The known storage devices have only relatively few storage locations for the caddy's, which means that the operator has to return to the machine at short intervals in order to attach new heads to the caddy's and ultimately to avoid that empty caddy's or caddy's with empty tubes are fed to the winding units.

Für Spulmaschinen mit einer größeren Anzahl von Spulstellen, die demzufolge einen höheren Verbrauch von neuen Kopsen haben, wäre eine derartige Speichereinrichtung für Caddy's, die von Hand mit Kopsen beschickt werden, unzureichend beziehungsweise würde bei entsprechender Vergrößerung einen unzumutbaren Platzbedarf erfordern.For winding machines with a larger number of winding units, which consequently have a higher consumption of new cops, such a storage device for caddies which are loaded with cops by hand would be insufficient or would require an unreasonable amount of space if they were enlarged accordingly.

Eine Speicherform, wie sie in der JP-A 52-25 139 beschrieben ist, oder auch eine mäanderförmige Speicherform, wie sie zum Beispiel in der DE-A 32 35 442 gezeigt ist, kommt für das Aufstecken der Kopse von Hand, insbesondere wenn es sich um sogenannte Großkopse handelt, nicht in Frage, da die Bedienungsperson in diesem Fall sich über Transportbahnen hinweg zum Aufstecken der Kopse beugen müßte, was aus ergonomischen Gründen nicht diskutabel ist.A storage form, as described in JP-A 52-25 139, or a meandering storage form, as shown for example in DE-A 32 35 442, comes for the attachment of the cops by hand, especially if it is it is a question of so-called large heads, not in question, since in this case the operator would have to bend over the conveyor tracks to attach the heads, which is not a question of ergonomic reasons.

Es ist Aufgabe der Erfindung, eine gattungsgemäße Speichervorrichtung so weiterzuentwickeln , daß ein hohes Speichervolumen und gleichzeitig eine bediengünstige Anordnung der Kopsaufsteckposition möglich ist.It is the object of the invention to further develop a generic storage device in such a way that a high storage volume and at the same time a convenient arrangement of the cop attachment position is possible.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Die erfindungsgemäße Anordnung unabhängiger Speicherstrecken mit gemeinsamen Transportstrecken bietet im Zusammenhang mit der Anwahl dieser Speicherstrecken über eine Speichersteuereinrichtung die Möglichkeit, daß unabhängig von der Speicherkapazität die Kopsaufsteckposition an einer wählbaren Stelle im Randbereich der Transportstrecken angeordnet werden kann. Dabei gewährleistet die Anordnung der Kopsaufsteckposition an gut zugänglicher Stelle insbesondere eine problemlose Handhabung der Kopse durch das Bedienpersonal.The arrangement according to the invention of independent storage sections with common transport sections, in connection with the selection of these storage sections via a storage control device, offers the possibility that the cop attachment position can be arranged at a selectable location in the edge region of the transport sections, regardless of the storage capacity. The arrangement of the cop attachment position at an easily accessible location ensures, in particular, problem-free handling of the cops by the operating personnel.

Die Anordnung der Kopsaufsteckposition im Bereich einer Transportstrecke, die sich von der Ausgangsseite der Speicherstrecken bis zum Spulenzulieferweg der Spulmaschine erstreckt sowie eine stromabwärts der Kopsaufsteckposition anschließende Abzweigung einer Überlaufstrecke gestatten dabei eine relativ einfache Verwaltung der gesamten Speichereinrichtung.The arrangement of the bobbin plug-on position in the region of a transport path which extends from the output side of the storage bins to the bobbin delivery path of the winding machine and a branching of an overflow path downstream of the bobbin plug-on position allow relatively simple administration of the entire storage device.

Da davon ausgegangen wird, daß die Kopsaufsteckleistung der Bedienungsperson deutlich über dem Kopsverbrauch der Spulmaschine liegt, muß die Bedienungsperson nur in größeren Zeitabständen an die gleiche Spulmaschine zurückkehren. Dabei muß gesichert sein, daß einerseits der Kopsaufsteckposition weitestgehend alle leeren, das heißt von ihren Hülsen befreiten Caddy's zugeführt werden können, andererseits aber auch die Caddy's mit aufgesteckten Kopsen, die nicht sofort der Spulmaschine zugeführt werden können, dem Speicher zuführbar sind. Dabei gestattet es die erfindungsgemäße Speichereinrichtung, die gleichen Speicherstrecken sowohl für Caddy's mit Kopsen als auch für leere Caddy's zu nutzen.Since it is assumed that the operator's cop attachment performance is significantly higher than the cop consumption of the winding machine, the operator only has to return to the same winding machine at longer intervals. It must be ensured that, on the one hand, all of the empty, that is, the caddy's, which have been freed from their sleeves, can be fed to the cops plug-on position, but on the other hand, the caddies with attached cops, which cannot be fed to the winding machine immediately, can be fed to the memory. The storage device according to the invention allows the same storage sections to be used both for caddies with cops and for empty caddies.

Die Erfindung ist vorteilhaft durch die Merkmale der Ansprüche 2 bis 17 weitergebildet.The invention is advantageously developed by the features of claims 2 to 17.

In bevorzugter Ausführungsform ist vorgesehen, die Kopsaufsteckposition im Randbereich der sich zwischen der gemeinsamen ausgangsseitig an die Speicherstrecken angeschlossenen Transportstrecke und dem Spulenzulieferweg der Spulmaschine erstreckenden Transportstrecke anzuordnen. Eine solche Anordnung ist für das Bedienpersonal besonders gut zugänglich.In a preferred embodiment it is provided to arrange the coping position in the edge region of the transport path extending between the common transport path connected on the output side to the storage paths and the spool delivery path of the winding machine. Such an arrangement is particularly accessible for the operating personnel.

In Weiterbildung der Erfindung können stromab der Kopsaufsteckposition im Bereich der Transportstrecke sowie der Überlaufstrecke mehrere Speicherpositionen vorgesehen werden. Der jeweilige Füllzustand der Speicherpositionen läßt sich dabei durch Sensoren leicht überwachen. Außerdem ist das gruppenweise Ein- und Ausschleusen von Caddy's mit Hilfe von Stoppern problemlos zu realisieren.In a further development of the invention, a plurality of storage positions can be provided downstream of the cop attachment position in the region of the transport path and the overflow path. The respective filling status of the storage positions can be easily monitored by sensors. In addition, the entry and exit of Caddy's in groups can be easily implemented with the help of stoppers.

Die Anordnung der Überlaufstrecke läßt sich im Rahmen der Erfindung mehrfach variieren. Sie ist abhängig vom Platzangebot sowie auch zum Beispiel der gewünschten Speicherkapazität derselben. Im Zusammenhang damit ist es auch möglich, die vom Hülsenrückführweg zu den Speicherstrecken führende Strecke an einem der beiden Enden der eingangsseitig an die Speicherstrecken angeschlossenen gemeinsamen Transportstrecke anzubinden.The arrangement of the overflow section can be varied several times within the scope of the invention. It depends on the space available and, for example, the desired storage capacity of the same. In connection with this, it is also possible to connect the line leading from the sleeve return path to the storage lines to one of the two ends of the common transport line connected on the input side to the storage lines.

Das Füllen und Entleeren der Speicherstrecken erfolgt vorteilhafterweise sukzessive von Strecke zu Strecke, wobei vorteilhafterweise leere Caddy's und mit Kopsen bestückte Caddy's durch eine Leerstrecke unterbrochen sind. Durch die jeweiligen Stauabschnitte ist es möglich, jeweils ganze Staustrecken zu füllen und zu entleeren. Dadurch verringert sich der Steuerungsaufwand. Außerdem sind steuerungstechnisch leere Caddy's und mit Kopsen bestückte Caddy's besser zu trennen.The storage sections are advantageously filled and emptied successively from section to section, advantageously empty caddies and caddies equipped with cops being interrupted by an empty section. Due to the respective stowage sections, it is possible to fill and empty entire stowage sections. This reduces the control effort. In addition, control-related empty caddy's and caddy's with cops are easier to separate.

Die Erfindung ist nachfolgend anhand von Ausführungsbeispielen näher erläutert. In den zugehörigen Zeichnungen zeigen:

The invention is explained in more detail below on the basis of exemplary embodiments. In the accompanying drawings:

Wie aus allen drei Zeichnungsfiguren zu erkennen ist, bildet die erfindungsgemäße Speichereinrichtung eine Transportschleife für die Caddy's 1 aus, die eingangsseitig an den Hülsenrückführweg 57 der Spulmaschine sowie ausgangsseitig an den Spulenzulieferweg 5 der im übrigen nicht dargestellten Spulmaschine angeschlossen ist.As can be seen from all three drawing figures, the storage device according to the invention forms a transport loop for the caddy's 1, which is connected on the input side to the sleeve return path 57 of the winding machine and on the output side to the bobbin delivery path 5 of the winding machine, which is otherwise not shown.

Da ein bekannter sogenannter Restetaster 61 eine Weiche 62 so betätigt, daß diese nur Caddy's 1 mit leeren Hülsen 3 durchläßt, erreichen auf dem Hülsenrückführweg 57 nur Caddy's 1 mit leeren Hülsen 3 eine Hülsenabzieheinrichtung 59. In der Hülsenabzieheinrichtung, die hier vereinfacht in Form eines Greifermechanismus' dargestellt ist, werden die Hülsen 3 von den Caddy's 1 entfernt und in einen Hülsenbehälter 60 abgelegt. Die Hülsenabzieheinrichtung 59 verlassen dann nur leere Caddy's 1.Since a known so-called residual switch 61 actuates a switch 62 so that it only allows caddy's 1 with empty sleeves 3 to pass, only caddy's 1 with empty sleeves 3 reach a sleeve pulling device 59 on the sleeve return path 57. In the sleeve pulling device, which here is simplified in the form of a gripper mechanism 'is shown, the sleeves 3 are removed from the caddy's 1 and placed in a sleeve container 60. The sleeve pulling device 59 then only leaves empty caddy's 1.

Die sich anschließende Transportstrecke 58 mündet in eine eingangsseitig an Speicherstrecken 9 bis 14 angeschlossene gemeinsame Transportstrecke 15. An dieser gemeinsamen Transportstrecke 15 sind Weichen 35 bis 39 angeordnet, die von einer Speichersteuereinrichtung 74 ansteuerbar sind. Sie gestatten die Zufuhr von Caddy's 1 in die jeweils vorgesehene Speicherstrecke.The subsequent transport path 58 opens into a common transport path 15 connected on the input side to storage paths 9 to 14. Points 35 to 39 are arranged on this common transport path 15 and can be controlled by a memory control device 74. They allow Caddy's 1 to be fed into the respective storage path.

Die Speicherstrecken 9 bis 14 sind ebenso, wie die übrigen Transportabschnitte durch Transportkanäle gebildet, innerhalb derer die Caddy's 1 mittels nicht gesondert dargestellter Transportbänder durch Reibschluß mitgenommen werden. Auf eine nähere Darstellung kann verzichtet werden, der derartige Transportstrecken bereits aus der eingangs genannten JP-A 52-25 139 bekannt sind. Ebenso wurde durchgängig auf die Darstellung der Antriebseinrichtungen für die Transportbänder der einzelnen Transportabschnitte verzichtet. Die Transportrichtung des Obertrumes der Transportbänder, die zwangsläufig mit der Transportrichtung der Caddy's 1 übereinstimmt, ist durch Richtungspfeile verdeutlicht.The storage sections 9 to 14, like the other transport sections, are formed by transport channels, within which the caddies 1 are taken along by friction by means of transport belts (not shown separately). There is no need for a more detailed description of the fact that such transport routes are already known from JP-A 52-25 139 mentioned at the beginning. Likewise, the representation of the drive devices for the conveyor belts of the individual transport sections has been dispensed with throughout. The direction of transport of the upper run of the conveyor belts, which inevitably corresponds to the direction of transport of the Caddy's 1, is illustrated by directional arrows.

Am jeweiligen Eingang der Speicherstrecken 9 bis 14 sind Sensoren 28 bis 33 angeordnet, die den Durchgang der Caddy's 1 feststellen und der Speichersteuereinrichtung 74 melden. Am ausgangsseitigen Ende der Speicherstrecken 9 bis 14 sind Stopper 16 bis 21 angeordnet, die, gesteuert durch die Speichersteuereinrichtung 74, die gespeicherten Caddy's 1 zurückhalten beziehungsweise das Leeren der Speicherstrecke gestatten. Benachbart zu diesen Stoppern 16 bis 21 sind weitere Sensoren 22 bis 27 angeordnet, die sowohl die Ankunft des jeweils ersten Caddy's 1 in einer zuvor leeren Speicherstrecke, als auch den Austritt des letzten Caddy's nach dem Leeren des Speichers feststellen. Letzteres geschieht entweder durch eine längere Pause nach dem Durchtritt eines Caddy's 1 oder durch Abzählen der den Sensor passierenden Caddy's, deren Anzahl pro Speicherstrecke bekannt ist. Allerdings besteht in diesem Zusammenhang auch die Möglichkeit, durch Abzählen der Caddy's eine Speicherstrecke nur teilweise zu entleeren und eine vorgebbare Anzahl von Caddy's auszuschleusen. Diese Speicherstrecke kann dann anschließend wieder aufgefüllt werden, wobei mittels des eingangsseitig angeordneten Sensors ebenfalls wieder das Abzählen der Caddy's ermöglicht wird. Auf diese Weise läßt sich ständig der jeweilige Füllzustand der Speicherstrecken überwachen.Sensors 28 to 33 are arranged at the respective input of the storage sections 9 to 14, which determine the passage of the caddies 1 and report them to the storage control device 74. Arranged at the output end of the storage sections 9 to 14 are stoppers 16 to 21 which, controlled by the storage control device 74, retain the stored caddies 1 or permit the storage section to be emptied. Adjacent to these stoppers 16 to 21 are further sensors 22 to 27, which both determine the arrival of the first caddy 1 in a previously empty storage section and the exit of the last caddy after the storage has been emptied. The latter occurs either through a longer pause after a caddy 1 has passed or by counting the caddy passing the sensor, the number of which is known per storage path. In this context, however, there is also the possibility of only partially emptying a storage section by counting the caddy's and discharging a predeterminable number of caddy's. This storage path can then be filled again, the counting of the caddies being made possible again by means of the sensor arranged on the input side. On in this way, the respective filling status of the storage sections can be monitored continuously.

Die Speicherstrecken 9 bis 14 münden in die ausgangsseitig angeordnete gemeinsame Transportstrecke 8, die in eine Transportstrecke 8' übergeht, welche ihrerseits zum Spulenzulieferweg 5 führt.The storage sections 9 to 14 open into the common transport section 8 arranged on the output side, which merges into a transport section 8 ', which in turn leads to the coil supply path 5.

An der Strecke 8' ist eine Kopsaufsteckposition 43 vorgesehen, an der, wie aus Fig. 2 ersichtlich, eine Bedienungsperson 76 Kopse 4 auf die Caddy's 1 aufsteckt, die sie aus einem Kopsbehälter 44 entnimmt. Stromab zur Kopsaufsteckposition 43 ist eine zweite Staustrecke 7 vorgesehen, an deren vorderem Ende der Stopper 46 angeordnet ist. Diese Staustrecke 7 ist mittels Sensoren 48 und 49 hinsichtlich ihres Füllzustandes überwachbar. Darüber hinaus kann auch mit diesen Sensoren 48 und 49, die mit der Speichersteuereinrichtung 74 verbunden sind, ein Abzählen der vorbeitransportierten Caddy's 1 mit Kopsen 4 erfolgen.A cop attachment position 43 is provided on the section 8 ′, at which, as can be seen in FIG. 2, an operator 76 attaches cops 4 to the caddies 1, which they remove from a cop container 44. A second storage section 7 is provided downstream of the cop plug-on position 43 and the stopper 46 is arranged at the front end thereof. This accumulation section 7 can be monitored with regard to its filling state by means of sensors 48 and 49. In addition, these sensors 48 and 49, which are connected to the memory control device 74, can also be used to count the caddies 1 transported past with cops 4.

Weiter stromab in Richtung zum Spulenzulieferweg 5 ist eine erste Staustrecke 6 vorgesehen, die zum Aufstauen der Caddy's 1 einen Stopper 47 an ihrem vorderen Ende besitzt und durch einen Sensor 50 an ihrem hinteren Ende hinsichtlich ihres Füllzustandes überwacht wird. Aus dieser ersten Staustrecke 6 wird jeweils der momentane Kopsbedarf der Spulmaschine gedeckt.Further downstream in the direction of the coil delivery path 5, a first accumulation section 6 is provided, which has a stopper 47 at its front end for accumulating the caddy's 1 and is monitored for its filling state by a sensor 50 at its rear end. From this first accumulation section 6, the instantaneous coping requirement of the winding machine is covered.

Nachfolgend sollen weitere Einzelheiten der Funktionsweise der Speichereinrichtung beschrieben werden:
Wie bereits eingangs erläutert, steht ein Restetaster 61 mit einer stromab angeordneten Weiche 62 in Verbindung. Hat der Restetaster 61 einen größeren, das heißt weiterverarbeitbaren Bewicklungsrest erkannt, wird die Weiche 62 in den Hülsenrückführweg 57 geschwenkt, so daß der Caddy 1, der den Restkops trägt, in die Verbindungsstrecke 69 umgeleitet wird, die bis zum Spulenzulieferweg 5 führt. Darüber hinaus wird aber auch die Weiche 64 betätigt, die diesen Caddy 1 von der Verbindungsstrecke 69 auf eine Abzweigbahn 68 umlenkt, an der eine sogenannte Kegelvorbereitungseinrichtung 66 angeordnet ist, die speziell für das Auffinden von Fadenenden an Restkopsen geeignet ist.Further details of the functioning of the memory device are to be described below:
As already explained at the beginning, a residual button 61 is connected to a switch 62 arranged downstream. If the rest button 61 has recognized a larger, that is to say further processable winding residue, the switch 62 is pivoted into the sleeve return path 57, so that the caddy 1, which the Restkops carries, is redirected into the link 69, which leads to the coil feed path 5. In addition, the switch 64 is also actuated, which deflects this caddy 1 from the connecting section 69 to a branch path 68, on which a so-called cone preparation device 66 is arranged, which is particularly suitable for locating thread ends on residual cops.

Hatte der Restetaster 61 einen nur geringen Fadenrest erkannt, dessen erneute Zuführung zur Spulstelle sich nicht lohnen würde, wird neben der Weiche 62 noch die Weiche 63 betätigt, die diesen Caddy 1 in die Abzweigbahn 67 umlenkt, an der eine Hülsenreinigungseinrichtung 65 angeordnet ist. Darüber hinausgehende Erläuterungen dieses spulmaschinenspezifischen Kreislaufes sind nicht erforderlich, da ein derartiges System bereits in der DE-A 39 19 542 beschrieben ist.If the remainder button 61 recognized only a small thread remainder, which would not be worth feeding again to the winding unit, the switch 63 is actuated in addition to the switch 62, which deflects this caddy 1 into the branch path 67, on which a tube cleaning device 65 is arranged. Further explanations of this winding machine-specific circuit are not necessary since such a system is already described in DE-A 39 19 542.

Alternativ zur Verwendung einer Kegelvorbereitungseinrichtung 66 ist es auch möglich, daß, wenn der Restetaster 61 einen Restkops oder einen ausgeworfenen Kops, dessen Fadenanfang der Spulstelle nicht zuführbar war, erkannt hat, diesen statt durch die Weiche 62 in die Verbindungsstrecke 69 zu leiten, an dieser vorbei weitertransportieren zu lassen. Dazu muß die Hülsenabzieheinrichtung 59 ebenfalls angesteuert werden, so daß sie diesen Restkops oder ausgeworfenen Kops nicht von dem ihn tragenden Caddy 1 entfernt. Dieser Caddy 1 mit Restkops oder ausgeworfenem Kops mit voller Bewicklung wird dann in die gleiche Speicherstrecke transportiert, in der er als leerer Caddy transportiert würde. Dieser Restkops oder ausgeworfene Kops wird dann der Bedienungsperson an der Kopsaufsetzposition 43 zugeführt, die, statt einen neuen Kops aufzusetzen, das Fadenende suchen und so ablegen kann, daß die in der Spulmaschine angeordnete normale Kopsvorbereitungseinrichtung dieses Fadenende lösen und entsprechend ablegen kann. Gegebenenfalls ist es dabei auch möglich, durch das beschriebene Abzählen der Caddy's den Weg derselben zu verfolgen und einer ganz bestimmten Speicherstrecke zuzuführen, die hierfür Speicherplätze frei haben muß.As an alternative to the use of a cone preparation device 66, it is also possible that if the remaining button 61 has recognized a remaining cop or an ejected cop, the thread start of which could not be fed to the winding unit, instead of leading it through the switch 62 into the connecting section 69, on this to be transported past. For this purpose, the sleeve pulling device 59 must also be activated so that it does not remove this remaining cop or ejected cop from the caddy 1 carrying it. This caddy 1 with remaining cops or ejected cops with full wrapping is then transported into the same storage path in which it would be transported as an empty caddy. This remaining bobbin or ejected bobbin is then fed to the operator at the bobbin mounting position 43, which, instead of putting on a new bobbin, can search for the thread end and deposit it in such a way that the normal bobbin preparation device arranged in the winding machine can release this thread end and deposit it accordingly. If necessary, it is also possible to use the counting the caddy's as described, to track the path of the same and to feed it to a very specific storage section which must have free storage spaces for this.

Bei der Darstellung in Fig. 1 werden die leeren Caddy's 1, bei denen der Aufsteckdorn 2 zu erkennen ist, von der Hülsenabzieheinrichtung 59 aus an einer Einmündung 53 einer Überlaufstrecke 52 vorbei einer Staustrecke 73 zugeführt. Am vorderen Ende dieser Staustrecke 73 ist ein Stopper 71 angeordnet, der ebenfalls eine Verbindung zur Speichersteuereinrichtung 74 besitzt. Ein benachbart angeordneter Sensor 72 überwacht auch an dieser Stelle den Durchgang der Caddy's, während ein weiterer Sensor 72' den Füllzustand dieser Staustrecke 73 bezüglich der leeren Caddy's 1 zu überwachen vermag.In the illustration in FIG. 1, the empty caddy's 1, in which the plug-on mandrel 2 can be seen, are fed from the sleeve pulling device 59 past an opening 53 to an overflow section 52 past a storage section 73. A stopper 71, which also has a connection to the memory control device 74, is arranged at the front end of this storage section 73. An adjacently arranged sensor 72 also monitors the passage of the caddy's at this point, while another sensor 72 ′ can monitor the filling status of this storage section 73 with respect to the empty caddy's 1.

In der in Fig. 1 dargestellten Phase, die zwischen zwei Aufsteckzyklen liegt, werden die Speicherstrecken, die Caddy's 1 mit Kopsen 4 tragen, allmählich entleert, da die Kopse 4 der Spulmaschine zugeführt werden, während die übrigen Speicherstrecken allmählich mit leeren Caddy's 1 gefüllt werden. Dabei ist es hinsichtlich der einfachen Verwaltung der Speicherstrecken 9 bis 14 vorgesehen, daß zwischen den Caddy's mit Kopsen führenden Speicherstrecken und den leere Caddy's führenden Speicherstrecken immer eine Speicherstrecke freibleibt. In Fig. 1 ist das die Speicherstrecke 12.In the phase shown in FIG. 1, which lies between two plug-on cycles, the storage sections which carry caddy's 1 with cops 4 are gradually emptied, since the cops 4 are fed to the winding machine, while the remaining storage sections are gradually filled with empty caddy's 1 . With regard to the simple management of the storage sections 9 to 14, it is provided that a storage section always remains free between the storage sections carrying cops and the empty storage sections. In FIG. 1, this is the storage section 12.

Durch das sukzessive Füllen beziehungsweise Leeren der Speicherstrecken wandert diese leere Speicherstrecke, die die beiden Speicherteile voneinander trennt, immer von einem Ende des Speichers zum anderen Ende. In Fig. 1 wird soeben die Speicherstrecke 11 von den Kopse 4 tragenden Caddy's 1 befreit, die der zweiten Staustrecke 7 zugeführt werden. Diese Speicherstrecke 11 wird als nächstes die leere Speicherstrecke bilden, während die Weiche 37 an der eingangsseitig angeschlossenen gemeinsamen Transportstrecke 15 so eingestellt ist, daß diese Speicherstrecke aus der Staustrecke 73 gelieferte leere Caddy's 1 aufnehmen kann. Die Weiche 37 bleibt dann so lange geöffnet, bis durch Abzählen der in die Speicherstrecke 12 eingetretenen leeren Caddy's 1 mittels des Sensors 31 festgestellt wurde, daß die Speicherstrecke 12 gefüllt ist. Anschließend wird die Weiche 37 in die gleiche Stellung bewegt, wie die Weichen 38 und 39 an den Speicherstrecken 13 und 14, die zuvor bereits geöffnet wurden. Zum Füllen der letzten Staustrecke, der Staustrecke 9, ist lediglich eine Führungskante 34 erforderlich, da die dort ankommenden Caddy's 1 in jedem Fall dieser Speicherstrecke zuzuführen sind.As a result of the successive filling or emptying of the storage sections, this empty storage section, which separates the two storage sections from one another, always moves from one end of the storage device to the other end. In FIG. 1, the storage section 11 has just been freed from the caddies 1 carrying the heads 4, which are fed to the second storage section 7. This storage path 11 will next form the empty storage path, while the switch 37 on the input side Connected common transport route 15 is set so that this storage route can accommodate empty caddy's 1 delivered from the storage route 73. The switch 37 then remains open until it has been determined by counting the empty caddies 1 that have entered the storage section 12 that the storage section 12 is filled. The switch 37 is then moved into the same position as the switches 38 and 39 on the storage sections 13 and 14, which have already been opened. To fill the last storage section, the storage section 9, only one leading edge 34 is required, since the caddies 1 arriving there must be fed to this storage section in any case.

Zum Umlenken der Caddy's von der Transportstrecke 58 in die eingangsseitig angeschlossene gemeinsame Transportstrecke 15 ist ebenfalls eine Führungskante 40 vorgesehen.A guide edge 40 is also provided for deflecting the caddies from the transport path 58 into the common transport path 15 connected on the input side.

Die aus der Speicherstrecke 11 ausgeschleusten und der zweiten Staustrecke 7 zugeführten Caddy's 1 mit Kopsen 4 werden dort gestaut und stehen für die Zuführung zur stromab angeordneten ersten Staustrecke 6 zur Verfügung. Stromab zu dem am vorderen Ende der Staustrecke 6 angeordneten Stopper 47 ist ein Sensor 51 angeordnet, mit dessen Hilfe die der Spulmaschine zugeführten Kopse 4 abgezählt werden, die vom Stopper 47 freigegeben wurden. Dieser Sensor 51 ist, ebenso wie der am Hülsenrückführweg 57 angeordnete Sensor 70, mit der Speichersteuereinrichtung 74, die die zentrale Steuereinheit für die Speichereinrichtung sowie gegebenenfalls für die gesamte Spulmaschine darstellt, verbunden.The caddies 1 with cops 4, which have been removed from the storage section 11 and fed to the second storage section 7, are stowed there and are available for feeding to the downstream first storage section 6. Downstream of the stopper 47 arranged at the front end of the accumulation section 6, a sensor 51 is arranged, with the aid of which the cops 4 fed to the winding machine, which have been released by the stopper 47, are counted. This sensor 51, like the sensor 70 arranged on the sleeve return path 57, is connected to the storage control device 74, which represents the central control unit for the storage device and, if appropriate, for the entire winding machine.

Wie das bei Spulmaschinen prinzipiell erforderlich ist und auf unterschiedliche Weise geregelt ist, werden die Kopse auch hier entsprechend dem Bedarf der Spulmaschine zugeteilt. Dieser Bedarf wird, ebenfalls wie allgemein üblich, am Austritt von Leerhülsen aus der Spulmaschine vom Sensor 70 gemessen. Die Speichersteuereinrichtung 74 steuert nach dem Durchgang einer oder mehrerer Hülsen 3 auf dem Hülsenrückführweg 57 das Öffnen des Stoppers 47. Hat der Sensor 51 eine entsprechende Anzahl Kopse festgestellt, wird der Stopper 47 wieder geschlossen. Sollte durch die Zeitverzögerung eine größere Anzahl Kopse 4 den Sensor 51 passiert haben, als Leerhülsen ausgestoßen wurden, wird diese Zahl in der Speichersteuereinrichtung mit berücksichtigt, die diese von der Anzahl daraufhin ausgestoßener Hülsen abzieht. Auf diese Weise wird immer die Anzahl der Kopse und Hülsen im direkten Spulmaschinenkreislauf konstant gehalten.As is necessary in principle with winding machines and is regulated in different ways, the cops are also allocated here according to the requirements of the winding machine. As is generally the case, this need is met at the exit of Empty tubes from the winding machine measured by sensor 70. The memory control device 74 controls the opening of the stopper 47 after the passage of one or more sleeves 3 on the sleeve return path 57. If the sensor 51 has determined a corresponding number of cops, the stopper 47 is closed again. If, due to the time delay, a larger number of cops 4 have passed sensor 51 when empty tubes have been ejected, this number is also taken into account in the memory control device, which subtracts this from the number of tubes then ejected. In this way, the number of cops and tubes in the direct winding machine cycle is always kept constant.

An der ausgangsseitig angeschlossenen gemeinsamen Transportstrecke 8 sind ebenfalls Führungsprofile 41 und 42 angeordnet, die die Caddy's jeweils in ihre vorgesehene Transportrichtung umlenken.Guide profiles 41 and 42 are likewise arranged on the common transport path 8 connected on the output side, which guide the caddies in each case into their intended transport direction.

Werden, wie das in Fig. 2 ersichtlich ist, von der Bedienungsperson 76 Kopse 4 auf die Caddy's 1 aufgesteckt, müssen die Kopse 4 tragenden Caddy's, die nach dem Auffüllen der ersten und zweiten Staustrecke 6 und 7 anfallen, zu den Speicherstrecken 9 bis 14 abgeleitet werden. Dazu ist gemäß Fig. 1 eine Überlaufstrecke 52 vorgesehen, die mittels einer Weiche 56 angesteuert werden kann. Diese Überlaufstrecke 52 besitzt an ihrem stromab liegenden Ende einen Stopper 54, so daß sie selbst auch als Staustrecke fungieren kann. Das Auffüllen dieser Überlaufstrecke 52 kann mittels des an ihrem eintrittsseitigen Ende angeordneten Sensors 55 überwacht werden, der ebenfalls mit der Speichersteuereinrichtung 74 verbunden ist. Wurde nun mit Hilfe des Sensors 55 ein bestimmter Füllzustand der Überlaufstrecke 52 festgestellt, der zum Beispiel der Länge einer Speicherstrecke 9 bis 14 entspricht, kann der Stopper 54 geöffnet werden, wenn die Staustrecke 73 leer ist. Dazu ist es erforderlich, daß zuvor der Stopper 71 geöffnet wurde, um die angestauten leeren Caddy's 1 aus der Staustrecke 73 zu entfernen. Weiterhin ist auch der Stopper 71' geschlossen zu halten, damit sich mit den aus der Überlaufstrecke 52 zugeführten Caddy's 1 mit Kopsen 4 keine leeren Caddy's vermischen. Die Verwaltung dieser Staustrecke 73 erfolgt dabei auf einfache Weise mit Hilfe der Sensoren 72 und 72' durch die stets feststellbar ist, ob sich in dieser Staustrecke 73 noch Caddy's befinden.If, as can be seen in FIG. 2, the operator 76 attaches cops 4 to the caddies 1, the cops 4 carrying caddies, which are produced after the first and second accumulation sections 6 and 7 have been filled, must go to the storage sections 9 to 14 be derived. 1, an overflow section 52 is provided, which can be controlled by means of a switch 56. This overflow section 52 has a stop 54 at its downstream end, so that it itself can also function as a storage section. The filling of this overflow section 52 can be monitored by means of the sensor 55 which is arranged at its entry end and which is likewise connected to the memory control device 74. If a certain filling state of the overflow section 52 has now been determined with the aid of the sensor 55, which for example corresponds to the length of a storage section 9 to 14, the stopper 54 can be opened when the storage section 73 is empty. This requires that before the stopper 71 has been opened in order to remove the pent-up empty caddy's 1 from the storage section 73. Furthermore, the stopper 71 'must also be kept closed so that no empty caddy's mix with the caddies 1 fed from the overflow section 52 with cops 4. The management of this storage section 73 is carried out in a simple manner with the aid of sensors 72 and 72 ', by means of which it can always be determined whether there are still caddies in this storage section 73.

Nachdem die aus der Staustrecke 73 ausgetragenen leeren Caddy's 1 ihr Ziel erreicht haben, was, wie bereits beschrieben, sensorisch überwachbar ist, muß eine entsprechende Umstellung der an der eingangsseitig angeschlossenen gemeinsamen Transportstrecke 15 angeordneten Weichen derart erfolgen, daß die mit frischen Kopsen 4 besetzten Caddy's 1 in eine andere, für sie vorgesehene Speicherstrecke eintreten können.After the empty caddies 1 discharged from the storage section 73 have reached their destination, which, as already described, can be monitored by sensors, a corresponding changeover of the switches arranged on the common transport route 15 connected on the input side must take place in such a way that the caddies occupied by fresh cops 4 1 can enter another storage path provided for them.

Bei der in Fig. 2 dargestellten Variante einer erfindungsgemäßen Speichereinrichtung ist, wie bereits erwähnt, die Phase des Kopsaufsteckens dargestellt. Dabei werden aus der Speicherstrecke 13 leere Caddy's 1 der Aufsteckposition 43 zugeführt. Um diese Aufsteckphase einzuleiten, muß die Bedienungsperson einen entsprechenden Befehl an die Speichersteuereinrichtung 74 geben, die dann auf den Kopsaufsteckmodus umschaltet. Die Bedienungsperson 76 kann an der Kopsaufsteckposition 43 des weiteren einen Stopper 45 betätigen, durch den die mit Kopsen zu bestückenden Caddy's an dieser Stelle angehalten werden. Allerdings besteht auch die Möglichkeit, diesen Stopper 45 nach der Inbetriebnahme des Kopsaufsteckungsmodus' automatisch taktweise zu öffnen, so daß die Bedienungsperson 76 ausschließlich mit dem Aufstecken der Kopse 4 auf die bereitgestellten Caddy's befassen muß. Dabei ist es auch von Vorteil, wenn die Kopsaufsteckposition einen begrenzten Bereich der Transportstrecke 8' umfaßt, so daß die Bedienungsperson beim Kopsaufstecken immer den Kopsbehälter 44 erreichen kann.In the variant of a storage device according to the invention shown in FIG. 2, as already mentioned, the phase of the coping is shown. In this case, empty caddies 1 are fed to the plug-on position 43 from the storage path 13. To initiate this slip-on phase, the operator must issue a corresponding command to the memory controller 74, which then switches to the cop plug-on mode. The operator 76 can also actuate a stopper 45 at the cops attachment position 43, by means of which the caddies to be equipped with cops are stopped at this point. However, there is also the possibility of automatically opening this stopper 45 in cycles after the start-up of the cop attachment mode, so that the operator 76 only has to deal with attaching the cops 4 to the caddies provided. It is also advantageous if the Kopsaufsteckposition covers a limited area of the transport route 8 ', so that the Operator can always reach the cop holder 44 when attaching the cop.

Insbesondere wenn es sich bei der Spulmaschine um eine sogenannte Großkopse, auf die zum Beispiel Teppichgarne aufgewickelt sind, verarbeitende Maschine handelt, ist im Verhältnis zu kleinen Kopsen die Ablaufzeit in der Spulstelle relativ lang. Damit ist die Zeitspanne zum Aufstecken eines Kopses 4 auf einen Caddy 1 wesentlich geringer als die Taktzeit für die Kopsanforderung der Spulmaschine. Dadurch ist es möglich, daß im Rahmen eines Kopsaufsteckzyklus die Speicherstrecken komplett (außer der freibleibenden Speicherstrecke, am Ende des Aufsteckzyklus' der Speicherstrecke 14) mit frischen Kopsen gefüllt werden. Auf diese Weise ergibt sich bei entsprechender Speicherkapazität eine relativ lange Zeitdauer, innerhalb derer die Bedienungsperson die Spulmaschine zum Aufstecken von Kopsen nicht aufsuchen muß.In particular if the winding machine is a so-called large bobbin on which, for example, carpet yarns are wound, a processing machine, the run-off time in the winding unit is relatively long in relation to small bobbins. The time span for attaching a cop 4 to a caddy 1 is thus considerably less than the cycle time for the cop request from the winding machine. This makes it possible for the storage sections to be completely filled with fresh cops (except for the remaining storage section, at the end of the plugging cycle of the storage section 14) within the scope of a coping cycle. In this way, with a corresponding storage capacity, there is a relatively long period of time within which the operator does not have to visit the winding machine for attaching cops.

In der Aufsteckphase in Fig. 2 wird soeben noch die erste Staustrecke 6 befüllt. Da der Sensor 50 am Ende dieser ersten Staustrecke 6 noch nicht feststellt, daß über einen längeren Zeitraum ein Caddy 1 mit Kops 4 neben ihm positioniert ist, werden zunächst noch die Caddy's 1 mit frisch aufgesteckten Kopsen 4 dieser ersten Staustrecke 6 zugeführt. Hat dann der Sensor 50 erkannt, daß diese erste Staustrecke 6 gefüllt ist, wird zunächst der Stopper 46 durch die Speichersteuereinrichtung 74 geschlossen, wonach die zweite Staustrecke 7 gefüllt wird, bis der Sensor 48 am Ende dieser Staustrecke ebenfalls deren Füllzustand erkennt. Daraufhin wird der Stopper 46 geöffnet und gleichzeitig die Weiche 56 umgeschaltet, so daß die vom Stopper 46 freigegebenen Caddy's 1 der Überlaufstrecke 85 zugeführt werden. Der Eingang dieser Überlaufstrecke 85 wird mittels eines Sensors 47 überwacht, der die in die Überlaufstrecke 85 eintretenden Caddy's 1 mit Kopsen 4 zählt. Am stromab liegenden Ende dieser Überlaufstrecke 85 ist ein Stopper 86 angeordnet, wodurch die Überlaufstrecke ebenfalls als, hier jedoch relativ kurze Staustrecke verwendbar ist.In the plug-on phase in FIG. 2, the first storage section 6 is just being filled. Since the sensor 50 at the end of this first storage section 6 does not yet detect that a caddy 1 with cops 4 is positioned next to it over a longer period of time, the caddies 1 with freshly attached cops 4 are first fed to this first storage section 6. If the sensor 50 then recognizes that this first accumulation section 6 is filled, the stopper 46 is first closed by the memory control device 74, after which the second accumulation section 7 is filled until the sensor 48 also recognizes its filling state at the end of this accumulation section. Thereupon the stopper 46 is opened and at the same time the switch 56 is switched over, so that the caddies 1 released by the stopper 46 are fed to the overflow section 85. The input of this overflow section 85 is monitored by means of a sensor 47 which detects the caddies 1 entering the overflow section 85 with cops 4 counts. A stopper 86 is arranged at the downstream end of this overflow section 85, as a result of which the overflow section can also be used as a, but here relatively short, storage section.

Da die Überlaufstrecke 85 und die sich an den Hülsenrückführweg 57 anschließende Transportstrecke 58 an verschiedenen Enden in die eingangsseitig angeschlossene gemeinsame Transportstrecke 77 münden, ist der Antrieb des Transportbandes der Transportstrecke 77 in beiden Richtungen möglich. Dementsprechend sind auch Weichen 79 bis 84 an den Eingängen der Speicherstrecken 9 bis 14 in zwei verschiedene Funktionsstellungen schaltbar, die durch die Weichen 81 und 83 demonstriert sind. Die Weiche 81 ist so eingestellt, daß Caddy's 1, die von der Überlaufstrecke 85 kommen, in die Speicherstrecke 11 transportiert werden können, wenn das Transportband der Transportstrecke 77 in Richtung auf seine Führungskante 78 beziehungsweise in Richtung zur Transportstrecke 58 transportiert. Die Weiche 83 ist bei umgekehrter Transportrichtung wirksam, wenn leere Caddy's aus der Staustrecke 73 in die Speicherstrecke 13 überführt werden sollen. Der reversierende Antrieb des Transportbandes der Transportstrecke 77 wird ebenfalls von der Speichersteuereinrichtung 74 gesteuert. Auch in diesem Falle ist eine Überwachung des Transports der Caddy's 1 notwendig, die jeweils an den entsprechenden Sensoren gezählt werden. Prinzipiell muß abgesichert werden, daß die sich auf der Transportstrecke 77 befindlichen Caddy's 1 in die jeweils für sie bestimmte Speicherstrecke eingetreten sein müssen, bevor die Transportrichtung des Transportbandes der Transportstrecke 77 wechselt.Since the overflow section 85 and the transport section 58 adjoining the sleeve return path 57 terminate at different ends in the common transport section 77 connected on the input side, the conveyor belt of the transport section 77 can be driven in both directions. Accordingly, switches 79 to 84 can also be switched to two different functional positions at the inputs of the storage sections 9 to 14, which are demonstrated by the switches 81 and 83. The switch 81 is set such that caddy's 1, which come from the overflow section 85, can be transported into the storage section 11 when the conveyor belt of the transport section 77 transports in the direction of its leading edge 78 or in the direction of the transport section 58. The switch 83 is effective in the opposite direction of transport when empty caddies are to be transferred from the storage section 73 into the storage section 13. The reversing drive of the conveyor belt of the conveyor line 77 is also controlled by the memory control device 74. In this case too, the transport of the caddy's 1 must be monitored, which are counted at the corresponding sensors. In principle, it must be ensured that the caddies 1 located on the transport path 77 must have entered the storage path intended for them before the transport direction of the conveyor belt of the transport path 77 changes.

Auch hier ist eine Staustrecke 73 vorgesehen, deren Füllzustand mittels eines Sensors 75 überwachbar ist. Allerdings ist kein weiterer Stopper erforderlich, da die Überlaufstrecke 85 nicht in die Transportstrecke 58 mündet.Here too, a storage section 73 is provided, the filling state of which can be monitored by means of a sensor 75. However, it is not a further stopper is required since the overflow section 85 does not open into the transport section 58.

Wie des weiteren aus Fig. 2 ersichtlich ist, ist es auch möglich, die Staustrecken, hier die Staustrecken 11 und 13, schrittweise zu füllen.As can further be seen from FIG. 2, it is also possible to fill the storage sections, here the storage sections 11 and 13, step by step.

Fig. 3 zeigt eine weitere Variante der Gestaltung der erfindungsgemäßen Speichereinrichtung. Dabei mündet die Transportbahn 89, die sich an den Hülsenrückführweg 57 anschließt, in eine Überlaufstrecke 93, die in die eingangsseitig angeschlossene gemeinsame Transportstrecke 93' übergeht. Durch diese gegenüber der Fig. 2 veränderte Bahnführung ist es nicht erforderlich, für diese gemeinsame Transportstrecke 93' einen Reversierantrieb vorzusehen. Darüber hinaus können auch die Weichen 97 bis 101 so ausgebildet werden, daß sie nur eine Arbeitsstellung besitzen.3 shows a further variant of the design of the storage device according to the invention. The transport path 89, which adjoins the sleeve return path 57, opens into an overflow path 93 which merges into the common transport path 93 'connected on the input side. As a result of this web guide, which has been changed compared to FIG. 2, it is not necessary to provide a reversing drive for this common transport route 93 '. In addition, the switches 97 to 101 can be designed so that they have only one working position.

Die Überlaufstrecke 93 besitzt vor der Einmündung der Transportbahn 89 einen Stopper 94, um ein Vermischen der Kopse 4 tragenden Caddy's 1 mit den leeren Caddy's 1 zu vermeiden. Am Abzweig der Überlaufstrecke 93 von der Transportbahn 8' ist ein Sensor 95 angeordnet, der der Überwachung der in die Überlaufstrecke 93 eintretenden Caddy's 1 dient. Ebenso ist an diesem Eingang, wie bereits bei den anderen Ausführungsbeispielen beschrieben, eine Weiche 56 vorhanden, die zwischen den beiden Staustrecken 6 und 7 liegt.The overflow section 93 has a stop 94 in front of the confluence of the transport path 89 in order to avoid mixing of the caddies 4 carrying caddies 1 with the empty caddies 1. A sensor 95 is arranged on the branch of the overflow section 93 from the transport track 8 ′ and is used to monitor the caddies 1 entering the overflow section 93. Also, as already described in the other exemplary embodiments, there is a switch 56 at this input, which lies between the two storage sections 6 and 7.

Die in Fig. 3 dargestellte Speicherphase zeigt einen Zustand, bei dem es bald erforderlich sein wird, daß die Bedienungsperson die Kopsaufsteckposition 43 aufsucht, um den Speicher wieder mit Caddy's 1 aufzufüllen, die Kopse 4 tragen. Zum gegenwärtigen Zeitpunkt sind die beiden Staustrecken 6 und 7 noch gefüllt, was die beiden Sensoren 48 und 50 erkennen. Allerdings ist auch die letzte Speicherstrecke, die Speicherstrecke 9, nur noch zum Teil mit Kopse 4 tragenden Caddy's 1 gefüllt.The storage phase shown in FIG. 3 shows a state in which it will soon be necessary for the operator to go to the head attachment position 43 in order to replenish the memory with caddies 1 carrying the heads 4. At the present time, the two accumulation sections 6 and 7 are still filled, which the two sensors 48 and 50 recognize. However, the last storage path is the Storage section 9, only partially filled with cops 4 carrying caddy's 1.

In dieser Speicherphase ist es von Vorteil, wenn die Speichersteuereinrichtung 74, die die gesamte Speichereinrichtung verwaltet, ein Signal auslöst, um die Bedienungsperson herbeizurufen. Dieser Zeitpunkt sollte nicht wesentlich später gewählt werden, um die ununterbrochene Versorgung der Spulmaschine mit Kopsen zu gewährleisten.In this storage phase, it is advantageous if the storage control device 74, which manages the entire storage device, triggers a signal in order to call the operator. This time should not be chosen much later in order to ensure the uninterrupted supply of cops to the winding machine.

Am Ende der Transportbahn 89 ist ein Stopper 92 sowie ein Sensor 91 vorgesehen. Dieser Stopper 92 steht am Anfang einer Speicherstrecke 90 auf der Transportbahn 89. Der Füllzustand dieser Speicherstrecke 90 ist hier mittels eines Sensors 88 möglich, der in einem Abstand vom Stopper 92 angeordnet ist, der der gewünschten Länge der Speicherstrecke 90 entspricht.A stopper 92 and a sensor 91 are provided at the end of the transport path 89. This stopper 92 is located at the beginning of a storage section 90 on the transport path 89. The filling state of this storage section 90 is possible here by means of a sensor 88 which is arranged at a distance from the stopper 92 which corresponds to the desired length of the storage section 90.

Im Bereich der Kopszuführung werden aus der ersten Staustrecke 6 auf Anforderung der Spulmaschine Caddy's 1 mit Kopsen 4 freigegeben. Der Sensor 50 fordert über die Speichersteuereinrichtung 74 aus der zweiten Staustrecke 7 neue Kopse an, um die erste Staustrecke 6 ständig gefüllt zu halten. Hat dann der in der Nähe des Stoppers 46 angeordnete Sensor erkannt, daß die zweite Staustrecke 7 leer wird, wird das Nachfüllen dieser zweiten Staustrecke 7 durch Öffnen des Stoppers 16 am Ausgang der Speicherstrecke 9 bewirkt. Das Nachfüllen leerer Caddy's 1 aus der Speicherstrecke 90 erfolgt bei der vorzugsweise angewendeten Steuerung erst dann, wenn die Staustrecke 9 vollständig geleert ist, um die jeweils eine leere Staustrecke zu sichern. Damit ergibt sich, daß vor dem Aufstecken neuer Kopse 4 die Speicherstrecke 9 leer ist, während nach dem Aufstecken der Kopse die Speicherstrecke 14 leer ist. Die leere Speicherstrecke "wandert" damit immer von einem Ende zum anderen Ende des Speichers.In the area of the cop feed, caddy's 1 with cops 4 are released from the first storage section 6 at the request of the winding machine. The sensor 50 requests 7 new cops from the second accumulation section 7 via the memory control device 74 in order to keep the first accumulation section 6 constantly filled. If the sensor arranged in the vicinity of the stop 46 then detects that the second storage section 7 is empty, the refilling of this second storage section 7 is effected by opening the stop 16 at the outlet of the storage section 9. In the case of the control which is preferably used, the refilling of empty caddy's 1 from the storage section 90 takes place only when the storage section 9 is completely emptied in order to secure the respective empty storage section. This means that the storage path 9 is empty before the new heads 4 are plugged in, while the storage path 14 is empty after the heads are plugged in. The empty storage path always "moves" from one end to the other end of the storage.
