Definitions

  • the invention relates to a spinning machine, in particular a ring spinning machine in combination with a winding machine according to the preamble of patent claim 1.
  • JP-OS 57-161 134 it is already known (JP-OS 57-161 134) to use the trunnion slides used in the winding machine connected to the ring spinning machine also as empty tube feed means or full tube discharge means by this trunnion slide, which generally consists of a circular disc and a vertical one center pins arranged thereon are displaced in a guide rail running around the ring spinning machine, the diameter, in particular the length, of a pin slide being slightly smaller than the distance between two adjacent spinning positions.
  • the individual pin slides are in contact with one another and are pushed forward by exerting force on one or more pin slides, the thrust force being at least partially transmitted by the direct contact of the pin slides.
  • a conveyor device for such trunnion slides is also known from DE-OS 35 44 560.
  • a disadvantage of the ring spinning machine according to JP-OS 57-161 134 is that the sleeve journals are not exactly in alignment with the spinning positions if a group of journal carriages with empty sleeves on one machine side has been moved in front of the assigned spinning stations. Therefore, before the sleeve change can be made, a rake at right angles to the longitudinal axis of the spinning machine between the trunnion slides in the known ring spinning machine be pushed so that the distances between the adjacent sleeve pins are coordinated exactly with the distances between adjacent spinning positions.
  • a reciprocating rail or the like extending along the spinning positions is used, which can be moved with a guide rail
  • the peg slide interacts in such a way that these are gradually moved to the assigned spinning position. So that the trunnion slides are precisely aligned with the assigned spinning station, they must either have a length exactly equal to the distance between the spinning stations, or there are pawl-like locking elements on the reciprocating rail, which are located exactly at the distance from the spinning stations, so that the locking elements ensure an exact alignment of the trunnion slides with the assigned spinning station even when the holding sledges are not in contact with one another.
  • the aim of the invention is to create a spinning machine, in particular a ring spinning machine, in combination with a winding machine of the type mentioned at the outset, in the case of the tube changing position of the endless conveyor an exact alignment of the sleeve pin relative to the assigned spinning station is to be ensured without the need for expensive mechanical measures that are prone to failure and require special maintenance, such as the introduction of rakes or the arrangement of pivoting pawls.
  • the idea of the invention is therefore that drivers are attached to the endless conveyor in exact positioning, which only have to be held in entraining mechanical engagement with the trunnion slides in order to ensure an exact alignment of the sleeve spigot with the assigned spinning position in the sleeve changing position of the endless conveyor.
  • this intervention occurs automatically when the trunnion slides have been transported to the spinning station.
  • an exact alignment of the trunnion with the spinning stations is ensured without excessive manufacturing and maintenance work having to be carried out for this purpose, although the trunnion carriages customary in winding machines are also used for supplying and removing the sleeves from the ring spinning machine.
  • the attachment of the drivers on the endless conveyor in precise alignment brings the essential advantage that the trunnion slides only come into engagement with the drivers at the loading station.
  • the trunnion slides can easily be removed from the drivers, while the precisely positioned drivers remain unchanged on the endless conveyor, which is realized in particular by a vertically arranged steel belt.
  • journal carriages which are guided in groups in an unsynchronized manner one after the other in the winding machine, are exactly positioned during the transition to the spinning machine by being brought into engagement in a controlled manner with the precisely positioned drivers.
  • the full sleeve Aragenden trolley at the end of the spinning group in question are removed from their exact positioning on the endless conveyor and fed to the normal transport system of the winding machine, which operates in a completely different cycle than the ring spinning machine. There is therefore no need for a timing interface between the ring spinning machine and the winding machine.
  • the main advantage of the combination of the spinning machine according to the invention is to be seen in the fact that one and the same trunnion slides on the spinning machine are brought into exact alignment with the individual spinning positions using the simplest means, namely the precisely positioned carriers the normal, unsynchronized transport of consecutive tenon slides takes place within the winding machine.
  • both debris of the endless conveyor on a single machine side, expediently, according to claim 3, both debris are equipped with drivers and trunnion slides.
  • the endless conveyor is guided around two mutually opposite machine sides of one or more spinning station groups, so that the full sleeves (cops) on both sides of the spinning machine can be exchanged for empty sleeves.
  • the endless conveyor can be suitably moved forwards or backwards at times by half a division of the spinning position.
  • the arrangement of the additional pins on the driver is particularly advantageous because conventional pin slides can thereby be used.
  • the measure according to claim 7 is provided.
  • the endless conveyor can only be used for advancing, but not for carrying the trunnion slides be used.
  • the support rail according to claim 8 is preferably provided for carrying the trunnion slide.
  • the mounting rail can also perform the longitudinal guidance of the trunnion according to claim 9.
  • the driver has a pure drive function.
  • the pin carriage is additionally guided by the driver, for example by being in a snap connection with the latter.
  • the drivers hold the trunnion magnetically.
  • a buffer path is expediently connected between the spinning machine and the winding machine in order to take into account somewhat different working speeds of the two machines.
  • a predetermined supply of full sleeves or empty sleeves, which are arranged on journal slides, is kept available on the buffer sections. If a buffer section is full, the subsequent device can be switched off for a certain period of time. Conversely, the device supplied can be temporarily switched off by suitable switching means, for example working with light barriers, when there are no more storage sleeves on the buffer line.
  • suitable switching means for example working with light barriers
  • the full heads can be removed from the sleeve journal on one buffer section.
  • the trunnion slides are also removed from the buffer section, fitted with a new sleeve and then placed on the second buffer section again. Thanks to the monitoring according to the invention, pin slides with full cops are always supplied and the pin slides with empty sleeves are conveyed back into the ring spinning machine.
  • the buffer sections which are to be protected against fiber flight, can also ensure that the full sleeves (cops) are largely protected against fiber flight by rapid transfer into the buffer section.
  • the buffer zone at the exit of the ring spinning machine should have a capacity approximately equal to the number of spinning stations supplying it.
  • the gripper-free transfer of the trunnion carriage from the spinning machine to the winding machine or the buffer section and vice versa can expediently be carried out according to claim 13.
  • a particularly advantageous development of the invention is characterized in accordance with claim 18 in that the drivers are arranged on the endless conveyor with adjustable length.

Description

Die Erfindung betrifft eine Spinnmaschine, insbesondere Ringspinnmaschine in Kombination mit einer Spulmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a spinning machine, in particular a ring spinning machine in combination with a winding machine according to the preamble of patent claim 1.

Es ist bereits bekannt (JP-OS 57-161 134), die bei der an die Ringspinnmaschine anschließenden Spulmaschine verwendeten Zapfenschlitten auch als Leerhülsen-Zufuhrmittel bzw. Vollhülsen-Abfuhrmittel zu verwenden, indem diese Zapfenschlitten, die im allgemeinen aus einer Kreisscheibe und einem senkrecht darauf angeordneten Mittelzapfen bestehen, in einer rund um die Ringspinnmaschine laufenden Führungsschiene verschoben werden, wobei der Durchmesser, insbesondere die Länge eines Zapfenschlittens geringfügig kleiner ist als der Abstand zweier benachbarter Spinnstellen. Die einzelnen Zapfenschlitten stehen in Berührung miteinander und werden durch Kraftausübung auf einen oder mehreren Zapfenschlitten vorangeschoben, wobei die Schubkraft zumindest teilweise durch die unmittelbare Berührung der Zapfenschlitten übertragen wird. Eine Fördervorrichtung für derartige Zapfenschlitten ist auch aus der DE-OS 35 44 560 bekannt.It is already known (JP-OS 57-161 134) to use the trunnion slides used in the winding machine connected to the ring spinning machine also as empty tube feed means or full tube discharge means by this trunnion slide, which generally consists of a circular disc and a vertical one center pins arranged thereon are displaced in a guide rail running around the ring spinning machine, the diameter, in particular the length, of a pin slide being slightly smaller than the distance between two adjacent spinning positions. The individual pin slides are in contact with one another and are pushed forward by exerting force on one or more pin slides, the thrust force being at least partially transmitted by the direct contact of the pin slides. A conveyor device for such trunnion slides is also known from DE-OS 35 44 560.

Nachteilig bei der Ringspinnmaschine nach der JP-OS 57-161 134 ist, daß die Hülsenzapfen sich nicht exakt in Ausrichtung mit den Spinnstellen befinden, wenn eine Gruppe von Zapfenschlitten mit Leerhülsen auf einer Maschinenseite vor die zugeordneten Spinnstellen verschoben worden ist. Deswegen muß, bevor der Hülsenwechsel vorgenommen werden kann, bei der bekannten Ringspinnmaschine ein Rechen rechtwinklig zur Spinnmaschinenlängsachse zwischen die Zapfenschlitten geschoben werden, damit die Abstände der benachbarten Hülsenzapfen exakt mit den Abständen benachbarter Spinnstellen koordiniert werden.A disadvantage of the ring spinning machine according to JP-OS 57-161 134 is that the sleeve journals are not exactly in alignment with the spinning positions if a group of journal carriages with empty sleeves on one machine side has been moved in front of the assigned spinning stations. Therefore, before the sleeve change can be made, a rake at right angles to the longitudinal axis of the spinning machine between the trunnion slides in the known ring spinning machine be pushed so that the distances between the adjacent sleeve pins are coordinated exactly with the distances between adjacent spinning positions.

Bei einer ähnlichen Hülsentransporteinrichtung (DE-OS l 37 12 027), die dem Förderer der Spinnmaschine gemäß vorliegender Erfindung am nächsten kommt, wird mit einer sich entlang der Spinnstellen erstreckenden hin- und hergehenden Schiene oder dergl. gearbeitet, welche mit in einer Führungsschiene verschiebbaren Zapfenschlitten derart zusammenwirkt, daß diese schrittweise bis zu der zugeordneten Spinnstelle verschoben werden. Damit die Zapfenschlitten mit der zugeordneten Spinnstelle exakt ausgerichtet sind, müssen sie entweder eine Länge exakt gleich dem Spinnstellenabstand aufweisen, oder es sind an der hin- und hergehenden Schiene klinkenartig verschwenkbare Sperrelemente vorgesehen, die sich genau im Abstand der Spinnstellen befinden, so daß die Sperrelemente eine genaue Ausrichtung der Zapfenschlitten mit der zugeordneten Spinnstelle auch dann gewährleisten, wenn die Halteschlitten nicht in Berührung miteinander stehen.In a similar tube transport device (DE-OS 1 37 12 027), which comes as close as possible to the conveyor of the spinning machine according to the present invention, a reciprocating rail or the like extending along the spinning positions is used, which can be moved with a guide rail The peg slide interacts in such a way that these are gradually moved to the assigned spinning position. So that the trunnion slides are precisely aligned with the assigned spinning station, they must either have a length exactly equal to the distance between the spinning stations, or there are pawl-like locking elements on the reciprocating rail, which are located exactly at the distance from the spinning stations, so that the locking elements ensure an exact alignment of the trunnion slides with the assigned spinning station even when the holding sledges are not in contact with one another.

Sowohl das Vorsehen eines besonderen Ausrichtungsrechens für die Zapfenschlitten (JP-OS 62-191 524) als auch die Anordnung von um eine Achse schwenkbaren Sperrklinken für jeden Zapfenschlitten (DE-OS 37 12 027) erfordern eine aufwendige Herstellung sowie einen erheblichen Raumbedarf. Die bekannten Anordnungen sind außerdem störanfällig und wartungsbedürftig.Both the provision of a special alignment rake for the trunnion slide (JP-OS 62-191 524) and the arrangement of pawls pivotable about an axis for each trunnion slide (DE-OS 37 12 027) require complex production and a considerable space requirement. The known arrangements are also prone to failure and require maintenance.

Das Ziel der Erfindung besteht darin, eine Spinnmaschine, insbesondere Ringspinnmaschine, in Kombination mit einer Spulmaschine der eingangs genannten Gattung zu schaffen, bei der in der Hülsenwechselstellung des Endlosförderers eine exakte Ausrichtung der Hülsenzapfen relativ zur zugeordneten Spinnstelle gewährleistet sein soll, ohne daß hierfür aufwendige, störanfällige und eine besondere Wartung erfordernde mechanische Maßnahmen wie die Einführung von Rechen oder die Anordnung schwenkbarer Klinken erforderlich sind.The aim of the invention is to create a spinning machine, in particular a ring spinning machine, in combination with a winding machine of the type mentioned at the outset, in the case of the tube changing position of the endless conveyor an exact alignment of the sleeve pin relative to the assigned spinning station is to be ensured without the need for expensive mechanical measures that are prone to failure and require special maintenance, such as the introduction of rakes or the arrangement of pivoting pawls.

Zur Lösung dieser Aufgabe sind die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 vorgesehen.To achieve this object, the features of the characterizing part of claim 1 are provided.

Der Erfindungsgedanke besteht also darin, daß am Endlosförderer in exakter Positionierung Mitnehmer angebracht sind, die lediglich mit den Zapfenschlitten in mitnehmendem mechanischen Eingriff gehalten werden müssen, um in der Hülsenwechselstellung des Endlosförderers eine exakte Ausrichtung der Hülsenzapfen mit der zugeordneten Spinnstelle zu gewährleisten. Dieser Eingriff liegt jedoch automatisch vor, wenn die Zapfenschlitten durch Mitnahme zur Spinnstelle gefördert worden sind. Auf diese Weise ist eine exakte Ausrichtung der Tragzapfen mit den Spinnstellen gewährleistet, ohne daß hierfür ein übertriebener Herstellungs- und Wartungsaufwand getrieben werden muß, obwohl die bei Spulmaschinen üblichen Zapfenschlitten auch für die Zu- und Abfuhr der Hülsen an der Ringspinnmaschine verwendet werden.The idea of the invention is therefore that drivers are attached to the endless conveyor in exact positioning, which only have to be held in entraining mechanical engagement with the trunnion slides in order to ensure an exact alignment of the sleeve spigot with the assigned spinning position in the sleeve changing position of the endless conveyor. However, this intervention occurs automatically when the trunnion slides have been transported to the spinning station. In this way, an exact alignment of the trunnion with the spinning stations is ensured without excessive manufacturing and maintenance work having to be carried out for this purpose, although the trunnion carriages customary in winding machines are also used for supplying and removing the sleeves from the ring spinning machine.

Die Anbringung der Mitnehmer am Endlosförderer in genauer Ausrichtung bringt den wesentlichen Vorteil, daß die Zapfenschlitten erst an der Beladestation mit den Mitnehmern in Eingriff gelangen. An der Entladestation können die Zapfenschlitten ohne weiteres von den Mitnehmern abgenommen werden, während die exakt positionierten Mitnehmer unverändert am Endlosförderer verbleiben, der insbesondere durch ein vertikal angeordnetes Stahlband verwirklicht ist.The attachment of the drivers on the endless conveyor in precise alignment brings the essential advantage that the trunnion slides only come into engagement with the drivers at the loading station. At the unloading station, the trunnion slides can easily be removed from the drivers, while the precisely positioned drivers remain unchanged on the endless conveyor, which is realized in particular by a vertically arranged steel belt.

Aufgrund der erfindungsgemäßen Ausbildung ist es auch möglich, einen schadhaft gewordenen Tragzapfen oder Zapfenschlitten gegen einen einwandfreien auszuwechseln, ohne daß die durch den Mitnehmer gewährleistende exakte Positionierung beeinträchtigt wird.Due to the training according to the invention, it is also possible to replace a damaged trunnion or trunnion slide with a perfect one without impairing the exact positioning guaranteed by the driver.

Erfindungsgemäß werden also die in der Spulmaschine unsynchronisiert unmittelbar hintereinander gruppenweise geführten Zapfenschlitten beim Übergang auf die Spinnmaschine exakt positioniert, indem sie in gesteuerter Weise mit den genau positionierten Mitnehmern nacheinander in Eingriff gebracht werden. Umgekehrt werden die eine volle Hülse Aragenden Zapfenschlitten am Ende der betreffenden Spinnstellengruppe aus ihrer exakten Positionierung am Endlosförderer entnommen und dem normalen Transportsystem der Spulmaschine zugeführt, welches in einem ganz anderen Takt als die Ringspinnmaschine arbeitet. Zwischen Ringspinnmaschine und Spulmaschine braucht es also keine Timing-Schnittstelle zu geben.According to the invention, the journal carriages, which are guided in groups in an unsynchronized manner one after the other in the winding machine, are exactly positioned during the transition to the spinning machine by being brought into engagement in a controlled manner with the precisely positioned drivers. Conversely, the full sleeve Aragenden trolley at the end of the spinning group in question are removed from their exact positioning on the endless conveyor and fed to the normal transport system of the winding machine, which operates in a completely different cycle than the ring spinning machine. There is therefore no need for a timing interface between the ring spinning machine and the winding machine.

Der wesentlicher Vorteil bei der Kombination der erfindungsgemäßen Spinnmaschine, insbesondere Ringspinnmaschine mit einer anschließenden Spulmaschine ist also darin zu sehen, daß ein und dieselben Zapfenschlitten auf der Spinnmaschine mit einfachsten Mitteln, nämlich den exakt positionierten Mitnehmern in exakte Ausrichtung mit den einzelnen Spinnstellen gebracht werden, während innerhalb der Spulmaschine der normale, unsynchronisierte Transport aufeinanderfolgender Zapfenschlitten erfolgt.The main advantage of the combination of the spinning machine according to the invention, in particular a ring spinning machine with a subsequent winding machine, is to be seen in the fact that one and the same trunnion slides on the spinning machine are brought into exact alignment with the individual spinning positions using the simplest means, namely the precisely positioned carriers the normal, unsynchronized transport of consecutive tenon slides takes place within the winding machine.

Am Übergang von der Spinnmaschine zur Spulmaschine werden keinerlei Greifer oder dergl. benötigt, denn die Mitnehmer des Endlosförderers der Spinnmaschine arbeiten unmittelbar mit den Fördermitteln einer Pufferstrecke oder der Spulmaschine zusammen.At the transition from the spinning machine to the winding machine, no grippers or the like are required, because the drivers of the endless conveyor of the spinning machine work directly with the conveying means of a buffer line or the winding machine.

Nach einer ersten Ausführungsform gemäß Anspruch 2 ist es möglich, beide Trümer des Endlosförderers auf einer einzigen Maschinenseite vorzusehen, wobei zweckmäßigerweise nach Anspruch 3 beide Trümer mit Mitnehmern und Zapfenschlitten bestückt sind.According to a first embodiment according to claim 2, it is possible to provide both debris of the endless conveyor on a single machine side, expediently, according to claim 3, both debris are equipped with drivers and trunnion slides.

Besonders bevorzugt ist es jedoch, wenn nach Anspruch 4 der Endlosförderer um zwei einander gegenüberliegende Maschinenseiten einer oder mehrerer Spinnstellengruppen herumgeführt ist, so daß in einem einzigen Arbeitsgang die vollen Hülsen (Kopse) auf beiden Seiten der Spinnmaschine gegen Leerhülsen ausgewechselt werden können.However, it is particularly preferred if, according to claim 4, the endless conveyor is guided around two mutually opposite machine sides of one or more spinning station groups, so that the full sleeves (cops) on both sides of the spinning machine can be exchanged for empty sleeves.

Aufgrund der Ausführungsform nach Anspruch 5 ist es möglich, die Leerhülsen zunächst auf dem Zusatzzapfen abzusetzen, damit der Hülsenzapfen für die Aufnahme der vollen Hülse zur Verfügung steht. Anschließend kann dann die Leerhülse vom Zusatzzapfen abgenommen und auf die Spindel der Spinnstelle aufgesetzt werden. Zur Durchführung dieses Doff-Vorganges kann der Endlosförderer in geeigneter Weise zeitweise um eine halbe Spinnstellenteilung vor- oder zurückgefahren werden. Besonders vorteilhaft ist die Anordnung der Zusatzzapfen am Mitnehmer, weil dadurch konventionelle Zapfenschlitten verwendet werden können.Due to the embodiment according to claim 5, it is possible to first place the empty sleeves on the additional pin, so that the sleeve pin is available for receiving the full sleeve. The empty tube can then be removed from the additional pin and placed on the spindle of the spinning station. In order to carry out this doffing process, the endless conveyor can be suitably moved forwards or backwards at times by half a division of the spinning position. The arrangement of the additional pins on the driver is particularly advantageous because conventional pin slides can thereby be used.

Eine besonders zweckmäßige Anordnung des Zusatzzapfens ergibt sich aus Anspruch 6.A particularly expedient arrangement of the additional pin results from claim 6.

Um bei Anordnung der Zusatzzapfen am Zapfenschlitten das Fördern des Zusatzzapfens um die gekrümmten Bereiche des Endlosförderers am Ende der Spinnstellengruppe zu erleichtern, ist die Maßnahme nach Anspruch 7 vorgesehen.In order to facilitate the conveying of the additional pin around the curved regions of the endless conveyor at the end of the spinning station group when the additional pins are arranged on the pin slide, the measure according to claim 7 is provided.

Nach einer Ausführungsform kann der Endlosförderer nur zum Vorschieben, nicht jedoch zum Tragen der Zapfenschlitten verwendet werden. Zum Tragen der Zapfenschlitten ist hierbei die Tragschiene nach Anspruch 8 bevorzugt vorgesehen.According to one embodiment, the endless conveyor can only be used for advancing, but not for carrying the trunnion slides be used. The support rail according to claim 8 is preferably provided for carrying the trunnion slide.

Die Tragschiene kann auch gemäß Anspruch 9 zusätzlich die Längsführung des Zapfenschlittens vornehmen. In diesem Fall hat der Mitnehmer eine reine Antriebsfunktion.The mounting rail can also perform the longitudinal guidance of the trunnion according to claim 9. In this case, the driver has a pure drive function.

Es ist jedoch auch möglich, daß nach Anspruch 10 der Zapfenschlitten durch den Mitnehmer zusätzlich geführt ist, indem er beispielsweise in einer Schnappverbindung mit diesem steht. Nach Anspruch 11 halten die Mitnehmer die Zapfenschlitten magnetisch.However, it is also possible that the pin carriage is additionally guided by the driver, for example by being in a snap connection with the latter. According to claim 11, the drivers hold the trunnion magnetically.

Nach Anspruch 12 ist zweckmäßigerweise eine Pufferstrecke zwischen die Spinnmaschine und die Spulmaschine geschaltet, um etwas unterschiedliche Arbeitsgeschwindigkeiten der beiden Maschinen zu berücksichtigen. Auf den Pufferstrecken wird jeweils ein vorbestimmter Vorrat an Vollhülsen bzw. Leerhülsen, die auf Zapfenschlitten angeordnet sind, bereitgehalten. Sofern eine Pufferstrecke voll ist, kann die jeweils nachliefernde Vorrichtung für einen gewissen Zeitraum abgeschaltet werden. Umgekehrt kann durch geeignete, beispielsweise mit Lichtschranken arbeitende Schaltmittel die belieferte Vorrichtung zeitweise abgeschaltet werden, wenn auf der Pufferstrecke keine Vorratshülsen mehr vorhanden sind. Die Weiterförderung der Zapfenschlitten auf den Pufferstrecken sollte zweckmäßig schubweise erfolgen, damit nicht für jeden zugeführten Zapfenschlitten ein Motor ein- und ausgeschaltet werden muß.According to claim 12, a buffer path is expediently connected between the spinning machine and the winding machine in order to take into account somewhat different working speeds of the two machines. A predetermined supply of full sleeves or empty sleeves, which are arranged on journal slides, is kept available on the buffer sections. If a buffer section is full, the subsequent device can be switched off for a certain period of time. Conversely, the device supplied can be temporarily switched off by suitable switching means, for example working with light barriers, when there are no more storage sleeves on the buffer line. The conveying of the trunnion slides on the buffer sections should be carried out in batches, so that a motor does not have to be switched on and off for each fed trunnion.

Besondere Vorteile liefert diese Ausführung bei defekter Spulmaschine. Normalerweise ist es nämlich bei defekter Spulmaschine sehr aufwendig, die Kopse von Hand zu entfernen. Wenn zeitkritische Signale vorhanden sind, ist das praktisch unmöglich, außer man erstellt spezielle Programmfunktionen.This version provides particular advantages if the winding machine is defective. Usually it is very difficult to remove the cops by hand if the winding machine is defective. If there are time-critical signals, this is practically impossible unless you create special program functions.

Erfindungsgemäß können jedoch an der einen Pufferstrecke die vollen Kopse von dem Hülsenzapfen abgenommen werden. Die Zapfenschlitten werden ebenfalls von der Pufferstrecke abgenommen, mit einer neuen Hülse bestückt und anschließend wieder auf die zweite Pufferstrecke gestellt. Dank der erfindungsgemäßen Überwachung werden immer wieder Zapfenschlitten mit vollen Kopsen nachgeliefert und die Zapfenschlitten mit leeren Hülsen wieder in die Ringspinnmaschine gefördert.According to the invention, however, the full heads can be removed from the sleeve journal on one buffer section. The trunnion slides are also removed from the buffer section, fitted with a new sleeve and then placed on the second buffer section again. Thanks to the monitoring according to the invention, pin slides with full cops are always supplied and the pin slides with empty sleeves are conveyed back into the ring spinning machine.

Durch die Pufferstrecken, die vor Faserflug geschützt sein sollen, kann auch erreicht werden, daß die Vollhülsen (Kopse) durch schnelles Überführen in die Pufferstrecke weitgehend vor Faserflug geschützt werden. Allerdings sollte in diesem Fall die Pufferstrecke am Ausgang der Ringspinnmaschine eine Kapazität annähernd gleich der Zahl der sie beliefernden Spinnstellen haben.The buffer sections, which are to be protected against fiber flight, can also ensure that the full sleeves (cops) are largely protected against fiber flight by rapid transfer into the buffer section. In this case, however, the buffer zone at the exit of the ring spinning machine should have a capacity approximately equal to the number of spinning stations supplying it.

Die greiferlose Überleitung der Zapfenschlitten von der Spinnmaschine auf die Spulmaschine bzw. die Pufferstrecke und umgekehrt kann zweckmäßigerweise gemäß Anspruch 13 erfolgen.The gripper-free transfer of the trunnion carriage from the spinning machine to the winding machine or the buffer section and vice versa can expediently be carried out according to claim 13.

Eine vorteilhafte Weiterbildung dieser Ausführungsform ist durch Anspruch 14 gekennzeichnet.An advantageous development of this embodiment is characterized by claim 14.

Wesentlich ist gemäß Anspruch 15, daß die exakte Positionierung der Zapfenschlitten durch die Mitnehmer nur an der Spinnmaschine, nicht jedoch auf der Spulmaschine oder auf den Pufferstrecken erfolgt.It is essential according to claim 15 that the exact positioning of the trunnion slides by the drivers only on the spinning machine, but not on the winding machine or on the buffer sections.

Vorteilhafte bauliche Ausgestaltungen der Ausleitvorrichtung bzw. der Einleitvorrichtung sind durch die Ansprüche 16 und 17 gekennzeichnet.Advantageous structural designs of the diversion device or the initiator device are characterized by claims 16 and 17.

Eine besonders vorteilhafte Weiterbildung der Erfindung kennzeichnet sich gemäß Anspruch 18 dadurch, daß die Mitnehmer längenverstellbar am Endlosförderer angeordnet sind. Auf diese Weise ist es möglich, die Mitnehmer noch nach dem Einbauen des Endlosförderers in die Ringspinnmaschine genau zu justieren, indem sie zunächst von dem Endlosförderer gelöst, dann solange in Längsrichtung der Maschine hin- und herverschoben werden, bis die vom Mitnehmer mitgenommenen Hülsenzapfen exakt mit der zugeordneten Spinnstelle ausgerichtet sind, worauf der Mitnehmer wieder am Endlosförderer festgelegt, beispielsweise festgeschraubt wird.A particularly advantageous development of the invention is characterized in accordance with claim 18 in that the drivers are arranged on the endless conveyor with adjustable length. In this way, it is possible to precisely adjust the drivers after the endless conveyor has been installed in the ring spinning machine by first detaching them from the endless conveyor and then pushing them back and forth in the longitudinal direction of the machine until the sleeve journals carried along by the driver are exactly with them the assigned spinning station are aligned, whereupon the driver is again fixed on the endless conveyor, for example screwed tight.

Baulich und funktionell besonders vorteilhaft ist die Ausbildung des Endlosförderers nach Anspruch 19.The construction of the endless conveyor according to claim 19 is particularly advantageous in terms of construction and function.

Anspruch 20 kennzeichnet eine weitere vorteilhafte Variante.Claim 20 characterizes a further advantageous variant.

Nach Fig. 1 weist eine Ringspinnmaschine 27 auf entgegengesetzten Maschinenseiten parallel zueinander verlaufende Spinnstellengruppen 12a und 12b auf, die jeweils aus nur schematisch angedeuteten Spinnstellen 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h bzw. 11i, 11k, 11l, 11m, 11n, 11o, 11p, und 11q bestehen. Der möglichst gleiche Spinnstellenabstand ist mit 24 bezeichnet. Weitere Einzelheiten der Ringspinnmaschine 27, insbesondere die Maschinenköpfe sind nicht gezeigt, weil es sich insoweit um übliche, bekannte Anordnungen handelt. Die Zahl der Spinnstellen 11 ist der Anschaulichkeit halber stark reduziert wiedergegeben.According to FIG. 1, a ring spinning machine 27 has parallel to one another on opposite machine sides Spinning station groups 12a and 12b, each consisting of only schematically indicated spinning stations 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h and 11i, 11k, 11l, 11m, 11n, 11o, 11p, and 11q. The same possible distance between spinning positions is designated by 24. Further details of the ring spinning machine 27, in particular the machine heads, are not shown because the arrangements in question are customary and known. For the sake of clarity, the number of spinning stations 11 is reproduced in a greatly reduced manner.

Um die beiden Spinnstellengruppen 12a, 12b ist ein Endlosförderer 17 in Form eines vertikal verlaufenden Stahlbandes herumgeführt, der an den beiden Enden der parallel und in Ausrichtung zueinander verlaufenden Spinnstellengruppen 12a, 12b um Umlenkwalzen 39, 40, 41, 42 mit vertikaler Achse herumgelegt ist. Es liegen somit zwei sich entlang jeweils einer Spinnstellengruppe 12a bzw. 12b erstreckende lange Trümer und zwei die beiden Spinnstellengruppen 12a, 12b an den Enden verbindende kurze Trümer des Endlosförderers 17 vor.An endless conveyor 17 in the form of a vertically extending steel belt is guided around the two spinning unit groups 12a, 12b and is placed around the deflecting rollers 39, 40, 41, 42 with a vertical axis at the two ends of the spinning unit groups 12a, 12b running parallel and in alignment with one another. There are therefore two long debris extending along a spinning group 12a or 12b and two short debris of the endless conveyor 17 connecting the two spinning unit groups 12a, 12b at the ends.

An dem als vertikales Stahlband ausgebildeten Förderer 17 sind ausgerichtet mit den einzelnen Spinnstellen 11a bis 11q sich vom Endlosförderer 17 nach außen erstreckende Mitnehmer 19a, 19b, 19c, 19d, 19e, 19f, 19g, 19h bzw. 19i, 19k, 19l, 19m, 19n, 19o, 19p und 19q befestigt. Unmittelbar neben und unter dem Endlosförderer 17 erstreckt sich im Bereich der Spinnstellengruppen 12a, 12b eine horizontale Tragschiene 22, die auch um das linke Ende der Ringspinnmaschine 27 parallel zum Endlosförderer 17 herumgeführt ist, um eine Transportverbindung zwischen den beiden Seiten der Ringspinnmaschine herzustellen.On the conveyor 17 designed as a vertical steel belt, drivers 19a, 19b, 19c, 19d, 19e, 19f, 19g, 19h and 19i, 19k, 19l, 19m, are aligned with the individual spinning positions 11a to 11q and extend outward from the endless conveyor 17. 19n, 19o, 19p and 19q attached. Immediately next to and below the endless conveyor 17, a horizontal support rail 22 extends in the area of the spinning station groups 12a, 12b, which is also guided around the left end of the ring spinning machine 27 parallel to the endless conveyor 17 in order to establish a transport connection between the two sides of the ring spinning machine.

Auf der Tragschiene 22 sind hintereinander im Abstand in Anlage mit den Mitnehmern 19a bis 19h bzw. 19i bis 19q Zapfenschlitten 18 angeordnet, welche nach Fig. 11 aus einem kreisscheibenförmigen Gleitkörper 44 und einem darauf senkrecht angeordneten Hülsenzapfen 13 bestehen, die aus Kunststoff vorzugsweise einstückig hergestellt sind.On the mounting rail 22 are in series with the drivers 19a to 19h or 19i to 19q in a pin carriage 18 arranged, which according to FIG. 11 consist of a circular disc-shaped sliding body 44 and a sleeve pin 13 arranged vertically thereon, which are preferably made in one piece from plastic.

An den beiden Spinnstellengruppen 12a und 12b sind jeweils zwei unterschiedliche Ausführungen von Mitnehmern dargestellt. An der Spinnstellengruppe 12a sind Mitnehmer 19a bis 19h mit hinter die Zapfenschlitten 18 greifenden mechanischen Mitnehmerfingern 45 vorgesehen, während an der gegenüberliegenden Spinnstellengruppe 12b Mitnehmer 19i bis 19q am Endlosförderer 17 angeordnet sind, die Permanentmagnete 46 enthalten, mittels denen die Zapfenschlitten 18 in einer weiter unten anhand von Fig. 3 beschriebenen Weise lösbar gehalten sind.Two different versions of carriers are shown on the two spinning station groups 12a and 12b. On the spinning unit group 12a, drivers 19a to 19h are provided with mechanical driver fingers 45 which reach behind the pin slides 18, while on the opposite spinning unit group 12b drivers 19i to 19q are arranged on the endless conveyor 17 which contain permanent magnets 46, by means of which the journal carriages 18 in a lower position are releasably held with reference to FIG. 3 described.

An beiden Maschinenseiten sind nach Fig. 1 gestrichelt angedeutete Hülsenwechselvorrichtungen 14 angedeutet, welche wie bei klassischen Doffern ausgebildet sein können und dazu dienen, von den Spindeln der Spinnstellen 11 Vollhülsen (Kopse) abzunehmen und stattdessen Leerhülsen 16 auf die Spindeln aufzustecken, welche mittels des Endlosförderers 17 an die einzelnen Spinnstellen 11 herangeführt worden sind.On both sides of the machine are shown in Fig. 1 dashed sleeve changing devices 14, which can be designed as in classic doffers and are used to remove 11 full sleeves (cops) from the spindles of the spinning stations and instead place empty sleeves 16 on the spindles, which are by means of the endless conveyor 17 have been introduced to the individual spinning stations 11.

Die Umlenkwalzen 41, 42 sind durch einen in Richtung der Doppelpfeile in Maschinenlängsrichtung beweglich gehaltenen Spannbalken 47 miteinander verbunden, der durch eine am Maschinengestell abgestützte Spannvorrichtung 48 unter eine den Endlosförderer 17 spannende Vorspannung gesetzt ist.The deflecting rollers 41, 42 are connected to one another by a tensioning beam 47 which is movable in the direction of the double arrows in the longitudinal direction of the machine and which is set by a tensioning device 48, which is supported on the machine frame, under a pre-tensioning tensioning the endless conveyor 17.

An einer geeigneten Stelle z.B. zwischen den Umlenkwalzen 39, 40 kann in nicht dargestellter Weise eine Reinigungsstation mit Blas- oder Saugdüsen und/oder Bürsten vorgesehen sein, um die Mitnehmer 19 und das Förderband 17 von Faserflug zu reinigen.At a suitable point, for example between the deflection rollers 39, 40, a cleaning station with blowing or suction nozzles and / or brushes can be provided in a manner not shown, in order to clean the carriers 19 and the conveyor belt 17 from fiber fly.

Des weiteren kann an irgendeiner stelle des Endlosförderers 17, die nicht bereits durch Mitnehmer 19 besetzt ist, ein Reinigungselement beispielsweise in Form einer Putzscheibe befestigt sein, welche bei einem Umlauf des Endlosförderers 17 auf der Tragschiene 22 entlanggleitet und diese dabei reinigt. Ein derartiges Reinigungselement kann bei sämtlichen Ausführungsbeispielen der Erfindung vorgesehen sein.Furthermore, a cleaning element, for example in the form of a cleaning disk, can be fastened at any point on the endless conveyor 17, which is not already occupied by the driver 19, which slides along the carrier rail 22 when the endless conveyor 17 rotates and thereby cleans it. Such a cleaning element can be provided in all embodiments of the invention.

An dem vom Spannbalken 47 abgewandten Ende der Spinnstellengruppen 12a, 12b sind durch Förderbänder 34, 35 gebildete Pufferstrecken 28, 29 in Ausrichtung mit den entlang der Spinnstellen 11 verlaufenden Abschnitte der Tragschienen 22 vorgesehen, an die sich eine nur schematisch angedeutete Spulmaschine 26 mit Führungsschienen 30 und Spulstellen 31 anschließt. Die Zahl der Spulstellen 31 ist um mindestens eine Größenordnung geringer als die Zahl der Spinnstellen 11.At the end of the spinning station groups 12a, 12b facing away from the tensioning beam 47, buffer sections 28, 29 formed by conveyor belts 34, 35 are provided in alignment with the sections of the support rails 22 running along the spinning stations 11, to which a winding machine 26 with guide rails 30 only indicated schematically and winding units 31 connects. The number of winding units 31 is at least one order of magnitude smaller than the number of spinning units 11.

Im Bereich des Überganges von der in Fig. 1 oberen Tragschiene 22 auf das unmittelbar an die Tragschiene 22 anschließende Förderband 34 ist ein Abweiser 36 vorgesehen, der die Zapfenschlitten 18 im Bereich der Umlenkwalze 39 ergreift und von den um die Umlenkwalze 39 herumgeführten Mitnehmern 19 trennt, so daß sie auf das im Bereich der Umlenkwalze 39 beginnende Förderband 34 gelangen.In the area of the transition from the upper support rail 22 in FIG. 1 to the conveyor belt 34 directly adjoining the support rail 22, a deflector 36 is provided, which grips the pin slides 18 in the region of the deflection roller 39 and separates them from the drivers 19 guided around the deflection roller 39 , so that they reach the conveyor belt 34 beginning in the region of the deflection roller 39.

Vor der in Fig. 1 unteren Umlenkwalze 40 ist ebenfalls ein Förderband 35 angeordnet, welches mit Leerhülsen 16 ausgestattete Zapfenschlitten 18 zunächst zu einem Halteanschlag 37 führt, welcher mittels einer durch eine Lichtschranke 49 gesteuerten Antriebsvorrichtung 50 zur Freigabe des jeweils vordersten Zapfenschlittens 18 kurzzeitig zurückgezogen werden kann. Die Förderbänder 34,35 werden gesteuert zeitweise oder während eines Hülsenwechselprozesses dauernd angetrieben.In front of the lower deflection roller 40 in FIG. 1, a conveyor belt 35 is likewise arranged, which first leads to the slide carriage 18 equipped with empty sleeves 16 to a stop 37, which is briefly withdrawn by means of a drive device 50 controlled by a light barrier 49 to release the foremost journal slide 18 can. The conveyor belts 34, 35 are driven in a controlled manner temporarily or continuously during a sleeve changing process.

Am vorderen Ende des Förderbandes 35 schließt sich die der Spinnstellengruppe 12a zugeordnete Tragschiene 22 an, so daß von dem Halteanschlag 37 freigegebene und mit Leerhülsen 16 bestückte Zapfenschlitten 18 vom Förderband 35 auf die stillstehende Tragschiene 22 geschoben und dort von dem Mitnehmerfinger 45 eines Mitnehmers 19 ergriffen werden können.At the front end of the conveyor belt 35, the support rail 22 assigned to the spinning group 12a connects, so that the pin carriage 18, released from the holding stop 37 and equipped with empty sleeves 16, is pushed from the conveyor belt 35 onto the stationary support rail 22 and gripped there by the driver finger 45 of a driver 19 can be.

Am Anfang und Ende eines jeden Förderbandes 34, 35 sind Lichtschranken 51, 52, 53, 54 vorgesehen, welche dazu dienen, die Anwesenheit bzw. Abwesenheit von Zapfenschlitten 18 an der betreffenden Stelle festzustellen und dementsprechend die Arbeitsweise der Transportvorrichtungen der Ringspinnmaschine 27 bzw. der Spulmaschine 26 zu steuern.At the beginning and end of each conveyor belt 34, 35, light barriers 51, 52, 53, 54 are provided, which serve to determine the presence or absence of trunnion slides 18 at the relevant point and accordingly the mode of operation of the transport devices of the ring spinning machine 27 and the Control winding machine 26.

Am vorderen Ende des Förderbandes 34 ist ein weiterer maschinell ein- und ausfahrbarer Halteanschlag 55 vorgesehen, welcher bei einem entsprechenden Vollhülsenbedarf der Spulmaschine 26 zeitweise zurückgezogen wird, um eine vorbestimmte Anzahl von Vollhülsen 15 zur Spulmaschine 26 durchzulassen.At the front end of the conveyor belt 34, a further mechanically retractable and extendable stop 55 is provided, which is temporarily withdrawn when the winding machine 26 has a corresponding full-sleeve requirement in order to allow a predetermined number of full-sleeves 15 to pass to the winding machine 26.

Die Arbeitsweise der beschriebenen Kombination einer Ringspinnmaschine mit einer Spulmaschine ist wie folgt:The described combination of a ring spinning machine with a winding machine works as follows:

In der in Fig. 1 dargestellten Position befindet sich vor jeder Spinnstelle 11 ein mit einer Leerhülse 16 bestückter Zapfenschlitten 18. Sobald die auf den Spindeln der Spinnstellen 11 angeordneten Hülsen mit Garn vollbespult sind, werden die auf den einzelnen Zapfenschlitten 18 befindlichen Leerhülsen 16 durch die Hülsenwechselvorrichtung 14 von den Tragzapfen 13 abgehoben, und es werden die auf den Spindeln der Spinnstellen befindlichen Vollhülsen (Kopse) 15 abgehoben und gegen die Leerhülsen 16 ausgetauscht. Die Vollhülsen 15 gelangen dabei auf die Tragzapfen 13 der zugeordneten Zapfenschlitten 18. Für den Hülsentausch erforderliche Zwischenzapfen 23 (Fig. 18 bis 22) sind der Anschaulichkeit halber in Fig. 1 nicht dargestellt.In the position shown in FIG. 1, in front of each spinning station 11 there is a journal slide 18 equipped with an empty sleeve 16. As soon as the sleeves arranged on the spindles of the spinning stations 11 are fully spooled with yarn, the empty sleeves 16 located on the individual journal carriages 18 are replaced by the The sleeve changing device 14 is lifted off the support pin 13, and the full sleeves (cops) 15 located on the spindles of the spinning positions are lifted off and exchanged for the empty sleeves 16. The full sleeves 15 arrive on the support pin 13 of the associated Pin carriage 18. Intermediate pin 23 (FIGS. 18 to 22) required for sleeve replacement are not shown in FIG. 1 for the sake of clarity.

Sobald der Austausch von Vollhülsen 15 und Leerhülsen 16 erfolgt ist, wird der Spinnvorgang an der Ringspinnmaschine 27 wieder aufgenommen, und der Endlosförderer 17 wird in Richtung des Pfeiles in Betrieb genommen, worauf die Vollhülsen 15 durch den Abweiser 36 sukzessive auf das Förderband 34 der Pufferstrecke 28 übergeben werden. Am anderen Ende des Förderbandes 34 ruft die Spulmaschine 30 die erforderliche Anzahl von Vollhülsen 18 ab, um an den Spulstellen 31 die endgültigen großen Spulen herzustellen.As soon as the exchange of full sleeves 15 and empty sleeves 16 has taken place, the spinning process on the ring spinning machine 27 is resumed, and the endless conveyor 17 is started in the direction of the arrow, whereupon the full sleeves 15 are successively pushed onto the conveyor belt 34 of the buffer zone by the deflector 36 28 are handed over. At the other end of the conveyor belt 34, the winding machine 30 calls up the required number of full tubes 18 in order to produce the final large bobbins at the winding stations 31.

Von der Führungsschiene 30 der Spulmaschine 26 werden die leergespulten Leerhülsen mit den sie tragenden Zapfenschlitten 18 auf das Förderband 35 der Pufferstrecke 29 gegeben, wobei sie sukzessive bis zum Halteanschlag 37 befördert werden. Auf diese Weise entsteht ebenso wie auf dem Förderband 34 eine Reihe von unmittelbar aneinanderliegenden Zapfenschlitten 18, die eine Reserve für die Übergabe an den Endlosförderer 17 darstellen.From the guide rail 30 of the winding machine 26, the empty-wound empty tubes with the journal carriages 18 carrying them are placed on the conveyor belt 35 of the buffer line 29, wherein they are successively conveyed to the stop 37. In this way, as well as on the conveyor belt 34, a series of pin carriages 18 lying directly against one another is created, which represent a reserve for the transfer to the endless conveyor 17.

Sobald ein Mitnehmer 19 mit Mitnehmerfinger 45 in die in Fig. 1 gestrichelt dargestellte Position unmittelbar vor der Umlenkwalze 40 kommt, gibt die Lichtschranke 49 über die gestrichelt angedeutete Steuerleitung 49' und die Antriebsvorrichtung 50 den Weg für den vordersten Zapfenschlitten 18 frei, indem der Halteanschlag 37 kurzzeitig zurückgezogen wird. Daraufhin verschiebt das Förderband 35 diesen Zapfenschlitten bis in die in Fig. 1 gestrichelt angedeutete Position 18'. Hier befindet sich der Zapfenschlitten bereits auf der stillstehenden Tragschiene 22. Er wartet jetzt, bis der Mitnehmerfinger 45 des Mitnehmers 19 ihn ergreift und entlang der Tragschiene 22 zur zugeordneten Spinnstelle der Spinnstellen 11a bis 11h bzw. 11i bis 11q fördert.As soon as a driver 19 with driver finger 45 comes into the position shown in dashed lines in FIG. 1 immediately in front of the deflection roller 40, the light barrier 49 via the control line 49 'indicated by dashed lines and the drive device 50 clears the way for the foremost journal carriage 18 by the stop 37 is withdrawn briefly. Thereupon, the conveyor belt 35 displaces this trunnion carriage into the position 18 'indicated by dashed lines in FIG. 1. Here the peg carriage is already on the stationary support rail 22. It now waits until the driver finger 45 of the driver 19 grips it and along the support rail 22 to the assigned spinning station of the spinning stations 11a to 11h or 11i to 11q.

Während bei der in der oberen Hälfte der Fig. 1 wiedergegebenen Ausführungsform der Mitnehmer mit Permanentmagneten 46 eine seitliche Führung der Zapfenschlitten durch die Tragschiene 22 nicht erforderlich ist, weil dies durch die Permanentmagnete 46 übernommen wird, weist die Tragschiene 22 bei der im unteren Teil der Fig.1 wiedergegebenen Ausführungsform mit mechanischen Mitnehmerfingern 45 auch noch eine seitliche Führung 56 auf.While in the embodiment of the driver with permanent magnets 46 shown in the upper half of FIG. 1, lateral guiding of the trunnion slides through the mounting rail 22 is not necessary because this is taken over by the permanent magnets 46, the mounting rail 22 has in the lower part of FIG 1 reproduced embodiment with mechanical driver fingers 45 also a lateral guide 56.

Da die Mitnehmer 19 auf dem Endlosförderer 17 in der in Fig. 1 dargestellten Hülsenwechselstellung exakt relativ zu den einzelnen Spinnstellen 11 positioniert sind, sind auch die von ihnen mitgenommenen Zapfenschlitten 18 und damit die an den Zapfenschlitten 18 befestigten Tragzapfen 13 exakt zu den einzelnen Spinnstellen 11 ausgerichtet. Die zunächst nicht vorhandene Ausrichtung wird beim Übergang vom Förderband 35 auf die Tragschiene 22 hergestellt, während sie beim Übergang der Vollhülsen 15 von der oberen Tragschiene 22 auf das Transportband 34 bewußt wieder aufgegeben wird, da jetzt wieder in den Takt der Spulmaschine 26 übergegangen wird.Since the drivers 19 are positioned on the endless conveyor 17 exactly in relation to the individual spinning stations 11 in the sleeve changing position shown in FIG. 1, the journal carriages 18 which they have taken along and thus the supporting journals 13 fastened to the journal carriage 18 are also exactly relative to the individual spinning stations 11 aligned. The initially non-existent alignment is produced during the transition from the conveyor belt 35 to the mounting rail 22, while it is deliberately given up again during the transition of the full sleeves 15 from the upper mounting rail 22 to the conveyor belt 34, since the cycle of the winding machine 26 is now changed again.

Bei der Ausführungsform nach Fig. 2, in der gleiche Bezugszahlen entsprechende Teile wie in Fig. 1 darstellen, ist ein Endlosförderer 17 mit beiden Trümern 20, 21 auf einer Maschinenseite entlang einer Spinnstellengruppe 12 angeordnet. Bei dieser Ausführungsform wechselt die Hülsenwechseleinrichtung 14 die auf den Spindeln der Spinnstellen 11 angeordneten Vollhülsen aus, indem sie zunächst die Vollhülsen 15 auf einen auf der am Trum 20 angeordneten Tragschiene 22 im Bereich der genau positionierten Mitnehmer 19' befindlichen Zapfenschlitten 18 absetzt und dann von dem von der Maschine abgewandten Trum 21 angeordneten Tragschiene 22 im Bereich der ebenfalls genau zu jeder Spinnstelle positionierten Mitnehmer 19'' eine Leerhülse 16 von den dort angeordneten Zapfenschlitten 18 abnimmt und auf die Spindeln der Spinnstellen 11 aufsetzt. Nachdem dieser Wechsel vollzogen ist, wird der Endlosförderer 17 eingeschaltet. Er befördert dann die Vollhülsen 15 sukzessive über das zur Pufferstrecke 28 gehörende Förderband 34 in die Spulmaschine 26, während die Spulmaschine 26 über das zur Pufferstrecke 29 gehörende Förderband 35 Zapfenschlitten 18 mit Leerhülsen 16 an das von den Spinnstellen 11 abgewandte Trum 21 des Endlosförderers 17 abgibt. Auf diese Weise kann während des Spinnvorganges an den Spinnstellen 11 ein kompletter Satz Vollhülsen 15 abgeführt und ein entsprechend voller Satz Leerhülsen 16 den einzelnen Spinnstellen zugeführt werden. Am Ende des Spinnvorganges, d.h., kurz bevor die auf den Spindeln steckenden Hülsen mit Garn gefüllt sind, in das Trum 21 leer, während das Trum 20 mit für ohne Aufnahme von Vollhülsen 15 bereiten Zapfenschlitten 18 bestückt ist.In the embodiment according to FIG. 2, in which the same reference numbers represent corresponding parts as in FIG. 1, an endless conveyor 17 with both debris 20, 21 is arranged on a machine side along a spinning group 12. In this embodiment, the sleeve changing device 14 exchanges the full sleeves arranged on the spindles of the spinning stations 11 by first placing the full sleeves 15 onto a journal slide 18 located on the support rail 22 arranged on the run 20 in the region of the precisely positioned drivers 19 'and then from the latter Carrier rail 22 arranged away from the strand 21 facing away from the machine in the region of the likewise precisely positioned to each spinning station Carrier 19 '' removes an empty sleeve 16 from the pin slides 18 arranged there and places it on the spindles of the spinning stations 11. After this change has been made, the endless conveyor 17 is switched on. He then conveys the full sleeves 15 successively via the conveyor belt 34 belonging to the buffer section 28 into the winder 26, while the winder 26 delivers pin journals 18 with empty sleeves 16 to the run 21 of the endless conveyor 17 facing away from the spinning stations 11 via the conveyor belt 35 belonging to the buffer section 29 . In this way, a complete set of full tubes 15 can be removed from the spinning stations 11 during the spinning process and a correspondingly full set of empty tubes 16 can be fed to the individual spinning units. At the end of the spinning process, ie shortly before the sleeves placed on the spindles are filled with yarn, the strand 21 is empty, while the strand 20 is equipped with trunnion slides 18 which are ready for receiving full sleeves 15.

In Fig. 3 sind drei Ausführungen von am Endlosförderer 17 mittels Schrauben 92' befestigten Mitnehmern 19 mit unterschiedlichen Ausführungsformen von Aufnahmeöffnungen 57 für die Zapfenschlitten 18 dargestellt. Während der erste Mitnehmer 19 eine muldenartige prismatische Aufnahmeöffnung 57 mit drei hintereinander angeordneten separaten Permanentmagneten 46 aufweist, ist die prismatische muldenartige Öffnung 57' des mittleren Mitnehmers 19 mit einem entsprechend prismatisch gestalteten Permanentmagneten 46 ausgestattet. Die Aufnahmeöffnung 57'' des dritten dargestellten Mitnehmers 19 ist teilkreisförmig und mit einem entsprechend teilkreisförmig gestalteten Permanentmagneten 46 ausgerüstet.3 shows three versions of drivers 19 fastened to the endless conveyor 17 by means of screws 92 ′ with different embodiments of receiving openings 57 for the pin slides 18. While the first driver 19 has a trough-like prismatic receiving opening 57 with three separate permanent magnets 46 arranged one behind the other, the prismatic trough-like opening 57 'of the central driver 19 is equipped with a correspondingly prismatic permanent magnet 46. The receiving opening 57 ″ of the third driver 19 shown is part-circular and is equipped with a permanent magnet 46 which is designed in the form of a part-circle.

Nach Fig. 11 ist der Gleitkörper 44 des Zapfenschlittens 18 am kreiszylindermantelförmigen Umfang mit insbesondere rundum verlaufenden Einlagen 58 aus einem weichmagnetischen Werkstoff, z.B. Stahl, versehen, welche nach Fig. 3 teilweise gegenüber den Permanentmagneten 46 zu liegen kommen, so daß sie von diesen angezogen und dadurch die Zapfenschlitten 18 an den Mitnehmern 19 in einer definierten Lage festgehalten werden. Nach den Fig. 4 und 12 werden mit Vollhülsen 15 bestückte Zapfenschlitten 18 am Ende der Ringspinnmaschine 17 bzw. am Ende einer Spinnstellengruppe durch einen Abweiser 36, gegen den die Zapfenschlitten 18 im Bereich der Umlenkwalze 39 anlaufen, von den Mitnehmern 19 getrennt und auf ein Förderband 34 überführt, welches an die Spulmaschine 26 (Fig. 1,2) angeschlossen ist.According to FIG. 11, the sliding body 44 of the peg slide 18 is made of a soft magnetic on the circumference in the form of a circular cylinder jacket, with inserts 58 running in particular all around 3, partially come to rest against the permanent magnets 46, so that they are attracted by them and thereby the pin slides 18 are held on the drivers 19 in a defined position. 4 and 12 are equipped with full sleeves 15 pin slides 18 at the end of the ring spinning machine 17 or at the end of a spinning group by a deflector 36, against which the pin slides 18 start in the region of the deflection roller 39, separated from the drivers 19 and on Conveyor belt 34 is transferred, which is connected to the winding machine 26 (Fig. 1,2).

Der Abweiser 36 ist gemäß Fig. 12 bügelförmig ausgebildet, derart, daß das vertikale Stahlförderband 17 und die vom Zapfenschlitten 18 gelösten Mitnehmer 19 durch die Bügelöffnung hindurchtreten können, um so auf die Umlaufwalze 39 zu gelangen und um diese herumgeführt zu werden.The deflector 36 is bow-shaped, as shown in FIG. 12, in such a way that the vertical steel conveyor belt 17 and the drivers 19 detached from the peg carriage 18 can pass through the bow opening, in order to get onto the circulation roller 39 and be guided around it.

In Förderrichtung unmittelbar hinter dem Abweiser 36 ist das Leerhülsen-Zufuhrförderband 35 vorgesehen, welches mit Leerhülsen 16 bestückte Zapfenschlitten 18 den am Abweiser 36 geleerten Mitnehmern 19 zuführt. Die Zufuhrrichtung f steht senkrecht auf dem Scheitel 17' des Förderbandes 17.In the conveying direction, directly behind the deflector 36, the empty tube feed conveyor belt 35 is provided, which feeds pin slides 18 equipped with empty tubes 16 to the carriers 19 emptied on the deflector 36. The feed direction f is perpendicular to the apex 17 'of the conveyor belt 17th

Sobald der vorderste Zapfenschlitten 18 von dem zugeordneten Mitnehmer 19 ergriffen worden ist, wird er seitlich aus der eine entsprechende Öffnung 59' aufweisenden Führungsbahn 59 für die mit Leerhülsen 16 bestückten Zapfenschlitten 18 herausbewegt, worauf dann durch das Förderband 35 die Reihe von Zapfenschlitten 18 um einen Zapfenschlitten vorgeschoben wird, damit der folgende leere Mitnehmer 19 entsprechend bestückt werden kann.As soon as the foremost journal carriage 18 has been gripped by the associated driver 19, it is moved laterally out of the guide path 59 having a corresponding opening 59 'for the journal carriages 18 equipped with empty sleeves 16, whereupon the row of journal carriages 18 by one by the conveyor belt 35 Pin carriage is advanced so that the following empty driver 19 can be equipped accordingly.

Nach den Fig. 5 und 6 überlappen sich benachbarte Mitnehmer 19, damit zwischen den Mitnehmern 19 keine Lücke entsteht, in welche die über das Förderband 35 nach Fig.4 zugeführten Zapfenschlitten 18 hineingelangen könnten. Auf diese Weise ist gewährleistet, daß vom Förderband 35 nach Fig. 4 nacheinander dem Endlosförderer 17 zugeführte und mit Leerhülsen 16 bestückte Zapfenschlitten 18 sukzessive in die Aufnahmeöffnungen 57 aufeinanderfolgender Mitnehmer 19 hineingelangen und dort durch die Permanentmagnete 46 festgehalten werden. Durch eine über den vordersten Zapfenschlitten 18 des Förderbandes 35 angeordnete Lichtschranke 60 kann festgestellt werden, ob jeweils ein Zapfenschlitten 18 vorhanden ist; sollte die Lichtschranke 60 das Fehlen eines solchen Zapfenschlittens 18 an dieser Stelle feststellen, so könnte durch geeignete Steuermittel der Endlosförderer 17 solange angehalten werden, bis vom Förderband 35 ein mit einer Leerhülse 16 bestückter Zapfenschlitten 18 nachgeliefert wird.5 and 6, adjacent drivers 19 overlap so that there is no gap between the drivers 19, into which the pin slides 18 fed via the conveyor belt 35 according to FIG. 4 could enter. In this way, it is ensured that the conveyor belt 35 according to FIG. 4 successively feeds the endless conveyor 17 and peg slides 18 equipped with empty sleeves 16 successively into the receiving openings 57 of successive drivers 19 and is held there by the permanent magnets 46. A light barrier 60 arranged above the foremost journal carriage 18 of the conveyor belt 35 can determine whether a journal carriage 18 is present in each case; Should the light barrier 60 determine the absence of such a peg carriage 18 at this point, the endless conveyor 17 could be stopped by suitable control means until a peg carriage 18 equipped with an empty sleeve 16 is supplied by the conveyor belt 35.

Fig. 7 zeigt, wie eine solche Lichtschranke 60 im einzelnen ausgestaltet sein könnte. Ein Lichtsender-Empfänger 61 sendet einen Lichtstrahl 62 nach oben durch den Bereich hin aus, in dem sich ein Zapfenschlitten 18 befinden müßte. Oberhalb dieses Bereiches ist ein Retroreflektor 63 vorgesehen, der beim Fehlen eines Zapfenschlittens 18 Licht in den Lichtsender-Empfänger 61 reflektiert, so daß dort ein entsprechendes Fehlsignal ausgelöst werden kann. Befindet sich ein Zapfenschlitten 18 im Weg des Lichtstrahls 62, so wird kein Licht zum Lichtsender-Empfänger 61 reflektiert und so an dem Lichtsender-Empfänger 61 kein Fehlsignal ausgelöst, so daß der Betrieb des Förderers 17 nicht unterbrochen werden muß.FIG. 7 shows how such a light barrier 60 could be designed in detail. A light transmitter-receiver 61 emits a light beam 62 upwards through the area in which a peg slide 18 should be located. Above this area, a retroreflector 63 is provided which, in the absence of a peg slide 18, reflects light into the light transmitter-receiver 61, so that a corresponding false signal can be triggered there. If there is a trunnion carriage 18 in the path of the light beam 62, no light is reflected to the light transmitter-receiver 61 and so no false signal is triggered at the light transmitter receiver 61, so that the operation of the conveyor 17 does not have to be interrupted.

Die Fig. 8 bis 10 zeigen verschiedene Ausführungen des aus Kunststoff bestehenden Bodens des Gleitkörpers 44 der Zapfenschlitten 18. Da dieser Boden auf der Tragschiene 22 aufliegt, kommt es hier auf besonders gute Gleiteigenschaften an.8 to 10 show different designs of the plastic base of the sliding body 44 of the pin slide 18. Since this base rests on the mounting rail 22, particularly good sliding properties are important here.

Der aus gut gleitfähigem und widerstandsfähigem Kunststoff bestehende Boden 64 nach Fig. 8 ist domförmig ausgebildet, so daß nur am Umfang eine gleitende Auflage auf der Tragschiene 22 vorliegt.The base 64 according to FIG. 8, which is made of good sliding and resistant plastic, is dome-shaped, so that there is only a sliding support on the support rail 22 on the circumference.

Der Boden 65 nach Fig. 9 besitzt drei nach unten vorstehende Gleitvorsprünge 67, die über den Außenumfang gleichmäßig verteilt sind.The floor 65 according to FIG. 9 has three sliding projections 67 which project downwards and are distributed uniformly over the outer circumference.

Der Boden 66 nach Fig. 10 weist im mittleren Bereich einen ebenen Auflagevorsprung 68 auf, so daß hier der Zapfenschlitten 18 nur in seinem mittleren Bereich gleitend auf der Tragschiene 22 zur Auflage kommt.The floor 66 according to FIG. 10 has a flat support projection 68 in the central area, so that here the trunnion slide 18 only slides on the support rail 22 in its central area.

Die Fig. 13 und 14 geben eine Ausführungsform wieder, bei welcher der Gleitkörper 44 der Zapfenschlitten 18 ausschließlich von den Mitnehmern 19 gehalten und geführt wird. Zu diesem Zweck sind die Mitnehmer 19 an dem vertikal verlaufenden Stahl-Förderband 17 befestigt, welches ebenso wie vorzugsweise auch die Mitnehmer 19 in maschinenfesten, oberen und unteren Längsführungen 69 bzw. 70 so geführt ist, daß auch die von den Zapfenschlitten 18 ausgeübten Kippmomente um die Förderrichtung von den Führungen 69, 70 aufgenommen werden.13 and 14 show an embodiment in which the sliding body 44 of the pin carriage 18 is held and guided exclusively by the drivers 19. For this purpose, the drivers 19 are fastened to the vertically extending steel conveyor belt 17, which, like preferably also the drivers 19, is guided in machine-fixed, upper and lower longitudinal guides 69 and 70 in such a way that the tilting moments exerted by the pin carriage 18 are also reduced the conveying direction can be received by the guides 69, 70.

Die Mitnehmer 19 sind nicht nur mit den muldenförmigen Vertiefungen 57 für die Aufnahme des Umfanges der Gleitkörper 44 versehen, sondern auch mit die Gleitkörper 44 von oben und unten übergreifenden Halteanschlägen 71,72. Da der Permanentmagnet 46 die Gleitkörper 44 in den so gebildeten Aufnahmeraum 43 der Mitnehmer 19 hineinzieht, sind somit die Zapfenschlitten 18 formschlüssig, jedoch durch den Abweiser 36 (Fig. 4) lösbar mit den Mitnehmern 19 und damit mit dem Förderband 17 verbunden.The drivers 19 are not only provided with the trough-shaped depressions 57 for receiving the circumference of the sliding bodies 44, but also with holding stops 71, 72 which overlap the sliding bodies 44 from above and below. Since the permanent magnet 46 pulls the sliding bodies 44 into the receiving space 43 of the driver 19 thus formed, the pin slides 18 are thus positively connected, but releasably connected to the drivers 19 and thus to the conveyor belt 17 by the deflector 36 (FIG. 4).

Bei dem Ausführungsbeispiel nach Fig. 15 weist das vertikale Stahl-Förderband 17 eine nach innen zu der Umlenkwalze 39 vorstehende Feder 73 auf, die in eine Umfangsnut 74 der Umlenkwalze 39 eingreift. Die übrigen Umlenkwalzen 40, 41, 42 besitzen entsprechende Umfangsnuten 74. Aufgrund dieser Maßnahme wird eine einwandfreie vertiakle Ausrichtung zwischen dem stahlband 17 und den Umlenkwalzen erzielt.In the exemplary embodiment according to FIG. 15, the vertical Steel conveyor belt 17 has an inwardly protruding spring 73 to the deflecting roller 39, which engages in a circumferential groove 74 of the deflecting roller 39. The other deflecting rollers 40, 41, 42 have corresponding circumferential grooves 74. This measure ensures that the vertical alignment between the steel strip 17 and the deflecting rollers is perfect.

Im unteren Bereich weist das vertikal stehende Förderband 17 eine nach außen weisende Feder 75 auf, die - in Förderrichtung verschiebbar - in eine entsprechende Nut 76 des Mitnehmers 19 eingreift. Durch schematisch angedeutete Klemmittel 77 kann der Mitnehmer 19 in verschiedenen Längspositionen relativ zum Förderband 17 festgelegt werden. Auf diese Weise ist eine Längsverstellung des Mitnehmers 19 relativ zum Endlosförderer 17 möglich.In the lower region, the vertically standing conveyor belt 17 has an outwardly pointing spring 75 which, displaceable in the conveying direction, engages in a corresponding groove 76 in the driver 19. By means of schematically indicated clamping means 77, the driver 19 can be fixed in different longitudinal positions relative to the conveyor belt 17. In this way, a longitudinal adjustment of the driver 19 relative to the endless conveyor 17 is possible.

In seinem unteren Bereich weist der Mitnehmer 19 eine T-förmige Führungsausnehmung 78 auf, mittels der er gleitend auf einem dazu komplementären Profil 79 mit T-Querschnitt aufliegt. Das T-Profil ist mit der Tragschiene 22 und der seitlichen Führung 56 fest verbunden, d.h. maschinenfest. Aufgrund dieser Führung der Mitnehmer 19 werden diese und auch das Förderband 17 zwischen den Umlenkwalzen 39, 40, 41, 42 auch in vertikaler Richtung einwandfrei abgestützt und geführt.In its lower area, the driver 19 has a T-shaped guide recess 78, by means of which it slidably rests on a profile 79 with a T cross section that is complementary thereto. The T-profile is firmly connected to the mounting rail 22 and the lateral guide 56, i.e. machine-proof. Due to this guidance of the drivers 19, these and the conveyor belt 17 are also supported and guided correctly in the vertical direction between the deflecting rollers 39, 40, 41, 42.

Der kreiszylinderförmige Gleitkörper 44 der Zapfenschlitten 18 ist auf der Tragschiene 22 gleitend gelagert und wird von dem Mitnehmerfinger 45 des Mitnehmers 19 vorgeschoben, wenn der Endlosförderer 17 in Umlauf versetzt wird.The circular-cylindrical sliding body 44 of the pin carriage 18 is slidably mounted on the mounting rail 22 and is advanced by the driver finger 45 of the driver 19 when the endless conveyor 17 is put into circulation.

Die seitlichen Führungen 56 sind an ihrem oberen Ende noch zu einem Führungsrand 80 abgebogen, so daß die Gleitkörper 44 von oben gegen ein Anheben gesichert sind und nur in der gewünschten Förderrichtung fortbewegt werden können.The lateral guides 56 are bent at their upper end to a guide edge 80, so that the sliding bodies 44 are secured against lifting from above and can only be moved in the desired conveying direction.

Nach den Fig. 16 und 17 ist der Endlosförderer 17 durch ein umlaufendes Stahlseil gebildet, an welchem die mit entsprechenden Aufnahmenuten 81 versehenen Mitnehmer 19 in einer gewünschten Längsposition durch Klemmittel 77 festgeklemmt sind. Auch auf diese Weise können die Mitnehmer 19 längenveränderlich am Endlosförderer 17 befestigt werden. Bei dieser Ausführungsform sind wieder Permanentmagnete 46 vorgesehen, die mit einer magnetischen Einlage 58 am Umfang des Gleitkörpers zusammenwirken.16 and 17, the endless conveyor 17 is formed by a circumferential steel cable, on which the drivers 19 provided with corresponding receiving grooves 81 are clamped in a desired longitudinal position by clamping means 77. In this way, too, the drivers 19 can be attached to the endless conveyor 17 in a variable length. In this embodiment, permanent magnets 46 are again provided, which cooperate with a magnetic insert 58 on the circumference of the sliding body.

Von der Unterseite des Mitnehmers 19 erstrecken sich mitnehmerfeste Führungsstifte 82 nach unten in eine Längsnut 83 der Tragschiene 22, wodurch in Zusammenwirkung mit der seitlichen Führung 56 auf der gegenüberliegenden Seite eine einwandfreie Längsführung der Zapfenschlitten 18 gewährleistet ist.Driver pins 82, which are fixed to the driver, extend downward from the underside of the driver 19 into a longitudinal groove 83 of the mounting rail 22, as a result of which, in cooperation with the lateral guide 56 on the opposite side, a perfect longitudinal guidance of the pin carriage 18 is ensured.

Nach den Fig. 18 bis 20 können die Zapfenschlitten 18 auch noch mit einem Zusatzzapfen 23 versehen sein, welcher gleich wie der Hülsenzapfen 13 ausgebildet ist. Zu diesem Zweck erstreckt sich vom Fuße des Zusatzzapfens 23 eine Verbindungslasche 84 zum Fuße des Hülsenzapfens 13, wo sie sich gabelt. Die beiden Gabelarme 84', 84'' umgreifen den Fuß des Hülsenzapfens 13 teilkreisförmig und sind federnd in eine Rundumnut 13'' eingeschnappt. Es wird so ein definierter Abstand 25 zwischen dem Hülsenzuapfen 13 und dem Zusatzzapfen 23 hergestellt, welcher der Hälfte des Abstandes 24 zweier Spinnstellen gleich ist.18 to 20, the pin carriage 18 can also be provided with an additional pin 23, which is designed in the same way as the sleeve pin 13. For this purpose, a connecting tab 84 extends from the foot of the additional pin 23 to the foot of the sleeve pin 13, where it forks. The two fork arms 84 ', 84' 'encompass the base of the sleeve pin 13 in the form of a circle and are snapped into an all-round groove 13' '. In this way, a defined distance 25 is produced between the sleeve pin 13 and the additional pin 23, which is equal to half the distance 24 between two spinning positions.

Aufgrund der Umfassung des Fußes des Hülsenzapfens 13 durch die gabelförmigen Enden 84', 84'' der Verbindungslasche 84 kann der Zusatzzapfen 23 auch um die Mittelachse 85 des Hülsenzapfens 13 schwenken, wie das durch den Doppelpfeil in Fig. 19 angedeutet ist. Diese Schwenkbarkeit hat den Sinn, daß der Hülsenzapfen 13 und der Zusatzzapfen 23 bei Anordnung in einer geradlinigen Führung 86 sich, wie das in Fig. 19 dargestellt ist, exakt hintereinander einstellen können, während beim Übergang der Führung 86 in einen gekrümmten Bereich 87 eine Relativverschwenkung zwischen den beiden Zapfen 13, 23 möglich ist, damit die Gesamtanordnung einwandfrei auch über gekrümmte Bereiche des Förderers 17 geführt werden kann.Due to the encircling of the base of the sleeve pin 13 by the fork-shaped ends 84 ', 84''of the connecting tab 84, the additional pin 23 can also pivot about the central axis 85 of the sleeve pin 13, as is indicated by the double arrow in FIG. 19. This swiveling has the meaning that the sleeve pin 13 and the additional pin 23, when arranged in a linear guide 86, can be set exactly one behind the other, as shown in FIG. 19, while when the guide 86 changes into a curved region 87 there is a relative pivoting between the two pins 13, 23 is possible so that the overall arrangement can also be properly guided over curved regions of the conveyor 17.

Nachdem sich der Zusatzzapfen 23 genau zwischen zwei aufeinanderfolgenden Hülsenzapfen 13 befindet, deren Gleitkörper 44 nahe beieinanderliegen, überlappt der Fuß 88 jedes Zusatzzapfens 23 den Gleitkörper 44 des unmittelbar folgenden Zapfenschlittens 18, muß also mit entsprechender Höhenversetzung ausgebildet sein.After the additional pin 23 is located exactly between two successive sleeve pins 13, the sliding bodies 44 of which lie close to one another, the foot 88 of each additional pin 23 overlaps the sliding body 44 of the immediately following pin slide 18, and must therefore be designed with a corresponding height offset.

Während die Hülsenzapfen 13 zur Zu- und Abfuhr von Leerhülsen 16 bzw. Vollhülsen 15 dienen, haben die Zusatzzapfen 23 den Sinn, beim Hülsenwechsel an einer spinnstelle 11 zeitweise die Leer- oder Vollhülse aufzunehmen, so daß sich die Anordnung eines derartigen Zusatzzapfens 23 an der Spinnmaschine selbst erübrigt.While the sleeve pins 13 are used to feed and remove empty sleeves 16 or full sleeves 15, the additional pins 23 have the sense of temporarily accommodating the empty or full sleeve when changing the sleeve at a spinning station 11, so that the arrangement of such an additional pin 23 on the Spinning machine itself unnecessary.

Nach Fig. 21 können die Zusatzzapfen 23 auch an den Mitnehmern 19 vorgesehen sein, welche zu diesem Zweck die Tragzapfen 13 bzw. deren Füße 13' gabelförmig vom Endlosförderer 17 her umgreifen, so daß hinter jedem Hülsenzapfen 13 eine Plattform 19''' entsteht, auf der sich der Zusatzzapfen 23 bei der halben Teilung 25 befindet. Nach den Fig. 21 und 22 ist der Zusatzzapfen 23 gleich wie die Hülsenzapfen 13 aufgebaut und weist auch die gleiche Anordnung in vertikaler Richtung auf.According to FIG. 21, the additional pins 23 can also be provided on the drivers 19, which for this purpose grip the support pins 13 or their feet 13 'in a fork shape from the endless conveyor 17, so that a platform 19' '' is formed behind each sleeve pin 13, on which the additional pin 23 is located at the half pitch 25. According to FIGS. 21 and 22, the additional pin 23 is constructed in the same way as the sleeve pin 13 and also has the same arrangement in the vertical direction.

Um die Zapfenschlitten 18 auch von vorn sicher zu halten und eine seitliche Führung zu vermeiden, sind die Füße 13' der Hülsenzapfen 13 von vorn durch einen sich vom Endlosförderer 17 wegerstreckenden Federarm 92 gehalten, der eine abgerundete Vertiefung 93 trägt, die sich um den kreiszylindrischen Fuß 13' von vorn teilweise herumlegt und so den Fuß 13' gegen die Plattform 19''' des Mitnehmers 19 drückt. Auf diese Weise brauchen die Zapfenschlitten 18 nur von unten durch die Tragschiene 22 gleitend abgestützt zu werden, während alle anderen Halterungs- und Führungsfunktionen von den Mitnehmern 19 übernommen werden.In order to hold the pin carriage 18 securely from the front and to avoid lateral guidance, the feet 13 'are the The sleeve pin 13 is held from the front by a spring arm 92 which extends away from the endless conveyor 17 and which carries a rounded recess 93 which partially wraps around the circular cylindrical foot 13 'from the front and thus the foot 13' against the platform 19 '''of the driver 19 presses. In this way, the pin slides 18 need only be supported in a sliding manner from below by the mounting rail 22, while all other mounting and guiding functions are taken over by the drivers 19.

Die Fig. 23 und 24 zeigen eine baulich besonders bevorzugte Verwirklichung der Erfindung. Die Tragschiene 22 ist als ein hohles und sich in Längsrichtung der Maschine erstreckendes Führungsprofil mit ebener oberer Gleitfläche ausgebildet, welches maschinenfest angeordnet ist. Der am Transportband 17 befestigte Mitnehmer 19 ist mittels einer Schraube 93' am Endlosförderer 17 befestigt und durch den Eingriff eines Vorsprunges 93 in einen Hohlraum 94 des Tragschienenprofils 22 allseitig an dem Tragschienenprofil 22 geführt.23 and 24 show a structurally particularly preferred implementation of the invention. The support rail 22 is designed as a hollow and extending in the longitudinal direction of the machine guide profile with a flat upper sliding surface, which is arranged fixed to the machine. The driver 19 fastened to the conveyor belt 17 is fastened to the endless conveyor 17 by means of a screw 93 ′ and is guided on all sides of the carrier rail profile 22 by the engagement of a projection 93 into a cavity 94 of the carrier rail profile 22.

Dadurch wird auch die Bewegung des wieder als vertikal angeordnetes Stahlband ausgeführten Endlosförderers 17 stabilisiert. Von einem vertikal nach oben gerichteten Arm 95 erstreckt sich oberhalb der oberen Fläche des Gleitkörpers 44 des Zapfenschlittens 18 die Mitnehmerplattform 19' nach hinten und außen, um den Fuß 13' des Hülsenzapfens 13 zu hintergreifen. Von vorn greift die über eine Blattfeder 92'' gegen den Fuß 13' gedrückte Backe 96 am Hülsenzapfen 13 an, so daß der Zapfenschlitten 18 allseitig lösbar gehalten und geführt und in Richtung vom Endlosförderer 17 weg abnehmbar ist.This also stabilizes the movement of the endless conveyor 17, again designed as a vertically arranged steel belt. The driver platform 19 ′ extends rearward and outward from a vertically upwardly directed arm 95 above the upper surface of the sliding body 44 of the pin carriage 18 in order to engage behind the foot 13 ′ of the sleeve pin 13. From the front, the jaw 96, which is pressed against the foot 13 'by means of a leaf spring 92' ', engages the sleeve journal 13 so that the journal carriage 18 is detachably held and guided on all sides and can be removed in the direction away from the endless conveyor 17.

Eine Spinnstellengruppe 12 besteht im allgemeinen aus 48 Spinnstellen. 3 bis 25 Spinnstellengruppen werden im zu einer Spinnmaschine zusammengestellt. Erfindungsgemäß läuft der Endlosförderer 17 an einer solchen Spinnmaschine entlang bzw. um diese herum, d.h., daß vorzugsweise nicht um jede einzelne Spinnstellengruppe, sondern um die Gesamtheit aller Spinnstellengruppen ein Endlosförderer 17 herumgeführt ist.A group of spinning units 12 generally consists of 48 spinning units. 3 to 25 spinning station groups are put together in a spinning machine. Runs according to the invention the endless conveyor 17 along or around such a spinning machine, that is to say that an endless conveyor 17 is preferably not guided around each individual spinning group, but rather around the entirety of all spinning groups.
