Abstract

A transport system for transporting laps wound on tubes in spinning preparation. The laps are transported above head height by carriers or supports movable along transport rails and are raised and lowered by means of carrier rails. The transport rails and the carrier rails are components or parts of a closed, endless circulation path or track. Each carrier has a holder for the lap and a holder for the empty tube. The invention provides the advantages that no special transport system is required for return of the tubes. Moreover, transport of individual laps or of a group of such laps is possible and an ordered and simple circulation path is provided during transport of these elements or parts. Furthermore, the system can readily be automated.

Description

Die vorliegende Erfindung bezieht sich auf eine Transportanlage für die Spinnereivorbereitung, zum Transportieren von Wattewickeln von einer ersten zu einer zweiten Maschine mittels Trägern, welche längs sich über Kopfhöhe befindlichen Transportschienen bewegbar sind, wobei sich die von den Transportschienen getragenen Wattewickel in grösserer Höhe über dem Boden befinden als die auf Wickelübergabestellen der Maschinen abgestellten Wickel, und an jeder Wickelübergabestelle eine in vertikaler Richtung bewegbare Tragschiene für die Träger vorgesehen ist.The present invention relates to a transport system for spinning preparation, for transporting wadding rolls from a first to a second machine by means of carriers which can be moved along transport rails located above head height, the wadding rolls carried by the transport rails moving at a greater height above the ground are located as the coils parked at the winding transfer points of the machines, and at each winding transfer point a support rail which can be moved in the vertical direction is provided for the carriers.

Durch die deutsche Auslegeschrift Nr. 1 288 490 ist eine Anlage bekannt, bei welcher Wickelträger längs eines endlosen Transportweges in vorgegebenen Abständen voneinander wandern. Die den Wickelträgern zu übergebenden Wickel werden angehoben und von den kontinuierlich bewegten Wickelträgern ergriffen. Die Wickel können nur einzeln übergeben und in gleichen Abständen voneinander transportiert werden. Diese Anlage erlaubt ein gleichzeitiges Beibringen einer Gruppe von Wickeln nicht. Ein Rückführen leerer Hülsen durch die Förderanlage ist ebenfalls nicht möglich. Vielmehr müssen die leeren Hülsen über ein spezielles Transportsystem rückgeführt werden.A layout is known from German Patent Application No. 1 288 490 in which winding carriers move along an endless transport path at predetermined distances from one another. The windings to be transferred to the winding carriers are raised and gripped by the continuously moving winding carriers. The wraps can only be transferred individually and transported at the same distance from each other. This system does not allow a group of coils to be taught simultaneously. Returning empty sleeves through the conveyor system is also not possible. Rather, the empty tubes have to be returned via a special transport system.

Das deutsche Gebrauchsmuster Nr. 74 24 750 betrifft eine Vorrichtung mit ebenfalls einem endlosen Transportband zum automatischen Transportieren von Wickeln. Bei diesem bewegen sich Wickelträger längs des Transportbandes. Auch bei dieser Vorrichtung können nicht gleichzeitig eine Mehrzahl von Wickeln herbeigeführt, bzw. eine Mehrzahl von Hülsen gleichzeitig weggeführt werden.German utility model no. 74 24 750 relates to a device with an endless conveyor belt for automatically transporting coils. With this, winding carriers move along the conveyor belt. In this device, too, a plurality of coils cannot be produced at the same time, or a plurality of sleeves can be removed at the same time.

Die japanische Patentschrift Sho 47-46 852 zeigt eine Anlage, bei welcher einer Transportschiene mittels einer Tragschiene eine Mehrzahl von Wickelträgern gleichzeitig zugeführt werden. Diese Transportschiene bildet keine in sich geschlossene Umlaufbahn, so dass die Wickelträger auf demselben Weg, auf dem sie an eine Maschine herangeführt wurden, wieder zurückbewegt werden müsssen. Dadurch ist man weniger frei im Transportieren der Träger. Ausserdem weisen die Träger keine dem Zurückführen von leeren Hülsen dienende Mittel auf. Das heisst, es sind auch bei dieser Transporteinrichtung eigens diesem Zweck dienende, gesonderte Mittel vorauszusehen.Japanese patent specification Sho 47-46 852 shows a system in which a plurality of winding carriers are simultaneously fed to a transport rail by means of a carrier rail. This transport rail does not form a closed orbit, so that the winding carriers have to be moved back in the same way in which they were brought to a machine. This means that you are less free to transport the carriers. In addition, the carriers have no means for returning empty tubes. This means that separate means are also to be provided for this purpose in this transport device.

Die im vorhergehenden beschriebenen Nachteile sollen gemäss der Erfindung vermieden werden. Diese ist dadurch gekennzeichnet, dass die Transportschienen und die auf deren Höhe gebrachten Tragschienen Teile einer in sich geschlossenen, endlosen Umlaufbahn bilden und jeder der Träger einen Halter für die Warrzwickel und einen Halter für die leeren Hülsen aufweist. Die Erfindung erlaubt somit einen Transport sowohl der Wattewickel als auch der leeren Hülsen längs einer geordneten und einfachen Umlaufbahn.The disadvantages described above should be avoided according to the invention. This is characterized in that the transport rails and the support rails brought to their height form part of a self-contained, endless orbit, and each of the carriers has a holder for the warmer packs and a holder for the empty sleeves. The invention thus allows transport of both the wadding and the empty tubes along an orderly and simple orbit.

In den Figuren sind gleiche Teil mit den gleichen Bezugszeichen versehen.In the figures, the same parts are provided with the same reference symbols.

Gemäss Figuren 1 und 2 ist eine Wattemaschine 11 vorhanden, welcher aus den Kannen 12 nicht gezeichnete Faserbänder zugeführt werden. In der Wattemaschine 11 werden die Faserbänder zu einer Watte zusammengefasst und aus der letzteren werden Wattewickel 13 gebildet. Der Wattewickel 13a befindet sich an einer Wickelübergabestelle 43 an der Wattemaschine 11. Transportschienen 14 sind Teile einer in sich geschlossenen, endlosen Umlaufbahn für Träger 15, welche längs der Umlaufbahn bewegbar sind. Die Träger 15 dienen zum Tragen und Transportieren von Wattewickeln 13 und von leeren Hülsen 26, Sie bewegen sich beim Transport in der durch den Pfeil 23 gegebenen Richtung.According to FIGS. 1 and 2, a wadding machine 11 is present, to which slivers (not shown) are fed from the cans 12. In the wadding machine 11, the fiber tapes are combined into a wadding and wadding rolls 13 are formed from the latter. The wadding roll 13a is located at a winding transfer point 43 on the wadding machine 11. Transport rails 14 are parts of a self-contained, endless orbit for carriers 15, which are movable along the orbit. The carriers 15 are used for carrying and transporting cotton rolls 13 and empty sleeves 26, they move during transport in the direction indicated by the arrow 23.

Eine Tragschiene 16 und Tragschienen 17, 18, welche in vertikaler Richtung bewegbar sind, sind ebenfalls Teile der Umlaufbahn. Diese setzt sich in dieser Ausführungsform aus den Transportschienen 14 und den Tragschienen 16, 17, 18 zusammen. Die Tragschiene 16 ist zwischen ihrer Position, welche sie zum Fassen eines sich an der Wickelübergabestelle 43 befindlichen Wickels 13a einnimmt und der Höhe der Transportschienen 14 auf- und ab bewegbar. In Figur 2 befindet sich der Wickel 13a auf der Wickelübergabestelle 43 in seiner vom Träger 15 gefassten Stellung und die Tragschiene 16 auf ihrer zum Fassen des Wickels 13a vorgesehenen Höhe oder Stellung. Auch die Tragschiene 18 befindet sich gemäss Figur 2 in ihrer aus der Höhe der Transportschienen 14 abgesenkten Lage, in welcher die drei von der Schiene 18 abgesenkten Wattewickel 13 auf die Wickelübergabestelle der Kehrstrecke 24 aufgesetzt sind. Die vertikalen Bewegungen der Tragschienen 16, 17 und 18 werden durch die in Figur 1 schematisch gezeichneten Hebeeinrichtungen 19. 20 und 21 erzeugt. Von den Tragschienen 17, 18 ist jede zur Aufnahme von je drei Wattewickeln 13 vorgesehen. Die Wattewickel 13 werden jeweils in Gruppen von drei Wickeln von den Tragschienen 17, 18 auf entsprechende Wickelübergabestellen abgesetzt.A support rail 16 and support rails 17, 18, which are movable in the vertical direction, are also parts of the orbit. In this embodiment, this is composed of the transport rails 14 and the support rails 16, 17, 18. The mounting rail 16 can be moved up and down between its position, which it assumes to hold a winding 13a located at the winding transfer point 43, and the height of the transport rails 14. In FIG. 2, the winding 13a is located on the winding transfer point 43 in its position gripped by the carrier 15 and the mounting rail 16 is at the height or position provided for gripping the winding 13a. According to FIG. 2, the mounting rail 18 is also in its position lowered from the height of the transport rails 14, in which the three wadding rolls 13 lowered from the rail 18 are placed on the winding transfer point of the sweeping path 24. The vertical movements of the mounting rails 16, 17 and 18 are generated by the lifting devices 19, 20 and 21 shown schematically in FIG. Each of the support rails 17, 18 is provided for accommodating three cotton rolls 13 each. The wadding rolls 13 are deposited in groups of three rolls from the support rails 17, 18 on corresponding winding transfer points.

Die Wattewickel 13 sind auf je eine Hülse 26a aufgewickelt. Jeder Träger 15 umfasst einen Halter 25 für einen Wattewickel 13. Der Halter 25 besteht im gezeigten Beispiel aus einer Klammer mit gegeneinander bewegbaren Backen, welche zum Erfassen eines Wattewickels 13 auf den beiden Stirnseiten der bewickelten Hülse 26a in diese eingetaucht werden. Der Träger 15 umfasst überdies einen Halter 28 für die leeren Hülsen 26. Dieser besteht gemäss vorliegendem Beispiel aus einem Stab, welcher sich von seiner Befestigungsstelle weg erstreckt und an welchem sich ein abgewinkeltes Stabstück 29 anschliesst, welches sich in bezug auf die Transportrichtung des Trägers 15 nach hinten erstreckt und dessen hinteres Ende ein freies Ende bildet. Auf die Stabstücke 29 werden die zu transportierenden, leeren Hülsen 26 aufgelegt bzw. aufgeschoben. Ein mit der Anlage fester Anschlag 30 dient zum Abstreifen der Hülsern 26 vom Stabstück 29. Jeder der Träger 15 ist von Rollen 27 getragen und mittels diesen längs den Transportschienen 14 und den Tragschienen 16, 17, 18 beförderbar. Die Transportschienen 14 sind an einem Gestell 31 befestigt. Sie befinden sich über Kopfhöhe. Der besseren Uebersichtlichkeit halber sind in Figur 1 die Träger 15 mit den Haltern 25 und 28 nicht gezeichnet. Andernteils sind aus demselben Grund in Figur 2 die Hebeerinrichtungen 19 und 21 nicht gezeichnet.The cotton rolls 13 are each on a sleeve 26a wound up. Each carrier 15 comprises a holder 25 for a wadding roll 13. In the example shown, the holder 25 consists of a clamp with jaws which can be moved relative to one another and which are immersed in the wrapped sleeve 26a on both ends in order to grasp a wadding roll 13. The carrier 15 also includes a holder 28 for the empty sleeves 26. According to the present example, this consists of a rod which extends away from its attachment point and to which an angled rod piece 29 adjoins which is in relation to the transport direction of the carrier 15 extends backwards and its rear end forms a free end. The empty sleeves 26 to be transported are placed or pushed onto the rod pieces 29. A stop 30 fixed with the system serves for stripping the sleeves 26 from the rod piece 29. Each of the supports 15 is carried by rollers 27 and can be conveyed along these along the transport rails 14 and the mounting rails 16, 17, 18. The transport rails 14 are fastened to a frame 31. You are above head height. For the sake of clarity, the carriers 15 with the holders 25 and 28 are not shown in FIG. 1. On the other hand, the lifting devices 19 and 21 are not shown in FIG. 2 for the same reason.

Im Betrieb der Transportanlage wird bei jedem Vorwärtsbewegen der Träger 15 um einen Schritt, ein Wattewickel 13 an der Wickelübergabestelle 43 der Wattemaschine 11 in die Umlaufbahn eingebracht. Zu diesem Zweck wird die Tragschiene 16 samt dem sich auf ihr befindlichen Träger 15 mittels der Hebeeinrichtung 19 abgesenkt, der sich an der Wickelübergabestelle 43 befindliche Wattewickel 13a mittels des Halters 25 des Trägers 15 erfasst und die Tragschiene 16 mittels der Hebeeinrichtung 19 wieder auf die Höhe gehoben, in welcher die Tragschiene 16 mit der Transportschiene 14 fluchtet.During operation of the transport system, each time the carrier 15 is moved forward by one step, a cotton roll 13 is introduced into the orbit at the winding transfer point 43 of the cotton machine 11. For this purpose, the mounting rail 16 together with the support 15 located thereon is lowered by means of the lifting device 19, the cotton roll 13a located at the winding transfer point 43 is gripped by means of the holder 25 of the support 15, and the mounting rail 16 is raised to the height by means of the lifting device 19 raised, in which the mounting rail 16 is aligned with the transport rail 14.

Bei angehobener Tragschiene 16 wird der sich auf dieser befindliche Träger 15 mit dem von ihm getragenen Wattewickel auf die Transportschiene 14 und in Richtung des Pfeiles 23 durch nicht gezeigte Mittel schrittweise weiterbewegt.When the support rail 16 is raised, the carrier 15 located on it is moved step by step onto the transport rail 14 and in the direction of the arrow 23 by means not shown, with the cotton wrap carried by it.

An der Kehrstrecke 24 wird mittels der Hebeeinrichtungen 20 und 21 jeweils je eine Gruppe von drei Wattewickeln 13 gleichzeitig abgesenkt. Dabei erfolgt das Absenken dieser Gruppen wechselweise. Falls drei Wattewickel 13 an der zur Tragschiene 17 gehörenden Wickelübergabestelle benötigt werden, werden drei Wickel 13 auf die Tragschiene 17 gebracht. Darauf wird diese abgesenkt und werden anschliessend drei in der Kehrstrecke 24 von aufgebrauchten Wickeln 13 frei gewordene Hülsen 26 auf die Hülsenhalter 28 bzw. Stabstücke 29 der sich auf der Tragschiene 17 befindlichen drei Träger 15 aufgesteckt. Anschliessend werden die Wattewickel 13 auf die Wickelübergabestelle abgesetzt und freigegeben. Schliesslich wird die Tragschiene 17 wieder angehoben, so dass sie wieder mit der Transportschiene 14 und der Tragschiene 18 fluchtet. Damit ist die Umlaufbahn wieder geschlossen. Wenn die sich auf der Tragschiene 18 befindlichen drei Wickel 13 benötigt werden, so erfolgt dies in einem Vorgang, welcher dem soeben anhand der Tragschiene 17 Beschriebenen entspricht. Die Notwendigkeit eines Beschreibens desselben erscheint sich deshalb zu erübrigen.At the sweeping section 24, a group of three cotton rolls 13 is lowered at a time by means of the lifting devices 20 and 21. These groups are lowered alternately. If three wadding rolls 13 are required at the winding transfer point belonging to the mounting rail 17, three rolls 13 are brought onto the mounting rail 17. Thereupon, the latter is lowered and then three sleeves 26, which have been freed in the sweeping section 24 from used windings 13, are placed on the sleeve holders 28 or rod pieces 29 of the three carriers 15 located on the mounting rail 17. The wadding rolls 13 are then placed on the roll transfer point and released. Finally, the mounting rail 17 is raised again so that it is again aligned with the transport rail 14 and the mounting rail 18. The orbit is closed again. If the three windings 13 located on the mounting rail 18 are required, this takes place in a process which corresponds to what has just been described with reference to the mounting rail 17. The need to describe it therefore appears to be superfluous.

Nachdem die sechs sich an den Wickelübergabestellen der Kehrstrecke 24 befindlichen Wattewickel 13 übergeben, sechs leere Hülsen 26 aufgesteckt und die Tragschienen 17, 18 wieder angehoben worden sind, werden die Träger 15 um sechs Schritte weiterbewegt und sechs neue Wattewickel 13 zur Kehrstrecke 24 gebracht.After the six cotton packs 13 located at the winding transfer points of the sweeping section 24 have been transferred, six empty sleeves 26 have been attached and the mounting rails 17, 18 have been raised again, the carriers 15 are moved six steps further and six new cotton packs 13 are brought to the sweeping section 24.

Die zur Wattemaschine 11 gelangenden, auf die Halter 28 bzw. Stabstücke 29 aufgesteckten Hülsen 26 stossen gegen einem Anschlag 30. Dadurch werden sie vom Stabstück 29 weggeschoben. Sie gelangen in einen Behälter 22 und sind damit zur Wiederverwendung für neue Wattewickel 13 bereit.The sleeves 26 which arrive at the wadding machine 11 and which are placed on the holder 28 or rod pieces 29 abut against a stop 30. As a result, they are pushed away from the rod piece 29. You get into a container 22 and are ready for reuse for new wadding 13.

Es ist ersichtlich, dass als Folge der durch die Transportschienen 14 und die Tragschienen 16, 17 und 18 gebildeten, in sich geschlossenen Umlaufbahn ein einfacher und damit störungsfreier Transport von Wattewickeln 13 und Hülsen 26 erhalten wird. Dieser kann in beliebigem Masse und je nach Wunsch manuell betrieben oder in mehr oder weniger hohem Mass automatisiert sein.It can be seen that, as a result of the closed orbit formed by the transport rails 14 and the support rails 16, 17 and 18, a simple and thus trouble-free transport of the cotton rolls 13 and sleeves 26 is obtained. This can be operated manually to any extent and as desired or automated to a greater or lesser extent.

Die Tragschiene 16 ist zum Heben einzelner Wattewickel 13 vorgesehen. In einer nicht gezeigten, abgeänderten Ausführungsform ist eine zum gleichzeitigen Heben einer Mehrzahl, z. B. dreier Wattewickel dienende Tragschiene vorgesehen. In einer weiteren, abgeänderten Ausführungsform kann der Hülsenhalter anstelle der gezeigten, stabförmigen Ausführung eine Mulde umfassen, in welche die leeren Hülsen 26 eingelegt werden. Auch in diesem Fall können bei zur Bewegungsrichtung der Träger parallel liegender Mulde die Hülsen 26 durch einen Anschlag 30 aus der Mulde weggeschoben werden.The support rail 16 is provided for lifting individual wadding 13. In a not shown, modified embodiment, one for simultaneously lifting a plurality, e.g. B. three wadding serving rail. In a further, modified embodiment, instead of the rod-shaped embodiment shown, the sleeve holder can comprise a trough into which the empty sleeves 26 are inserted. In this case, too, with a trough lying parallel to the direction of movement of the carrier, the sleeves 26 can be pushed out of the trough by a stop 30.

Die Wattemaschine 11 liefert die Faserwatte in Form eines endlosen Stranges. Wenn ein Wattewickel voll ist, so muss daher der Strang getrennt werden. In einer speziell vorteilhaften Ausführungsform sind die Träger 15 mit einer Halteleiste 32 versehen, welche gegen den Wattewickel 13 (bzw. 13a) hin vorgespannt ist. Die Halteleiste 32 ist senkrecht zur Zeichenebene der Figur 2 angeordnet. Sie ist an jedem ihrer Enden von einem Arm 33 getragen. Die Arme 33 sind um eine in Figur 2 zur Zeichenebene senkrecht stehende Achse 34 schwenkbar. Die Vorspannung der Halteleiste 32 kann beispielsweise durch um die Achse 34 gewundene, nicht gezeigte Spiralfedern erzeugt werden.The wadding machine 11 delivers the fiber wadding in the form of an endless strand. When a wad of cotton is full, the strand must therefore be separated. In a particularly advantageous embodiment, the carriers 15 are provided with a holding strip 32 which is prestressed against the cotton roll 13 (or 13a). The holding strip 32 is arranged perpendicular to the plane of the drawing in FIG. 2. It is supported by an arm 33 at each of its ends. The arms 33 can be pivoted about an axis 34 which is perpendicular to the plane of the drawing in FIG. The pretensioning of the holding strip 32 can be generated, for example, by spiral springs, not shown, which are wound around the axis 34.

Durch das für den Transport des Wattewickels 13 notwendige Trennen des Wattestranges entsteht ein äusseres freies Wattenende 35. Die an den Wattewickel 13 bzw. 13a anliegende Halteleiste 32 hält dieses Watteende 35, so dass der Wattewickel 13 ohne einen lose herunterhängenden Teil auf mühelose Weise transportiert werden kann.The separation of the cotton strand necessary for the transport of the cotton roll 13 creates an outer free cotton end 35. The holding strip 32 which is in contact with the cotton roll 13 or 13a holds this cotton end 35, so that the cotton roll 13 comes down without loosely the hanging part can be transported easily.

Beim Erfassen der Wattewickel 13a an der Wattemaschine 11 befindet sich die Bedienungsperson in der Darstellung der Figur 2 links vom Wickel 13a und kann das Wattenende 35 unter Wegschwenken der Leiste 32 um die Achse 34 mühelos zwischen der Leiste 32 und dem Wikkel 13a durchziehen. Wenn die Wickel 13 an der Kehrstrecke 24 eingetroffen sind, so befinden sich die Wattenenden 35 gemäss Figur 2 auf der linken Seite der Wattewickel13. Dies ist die Seite, auf der sich das Bedienungspersonal befindet. Damit ist das Wattenende 35 an dieser Maschine besonders leicht zugänglich und kann auf einfache Weise in die Kehrstrecke 24 zur weiteren Verarbeitung eingeführt werden. Der Wattewickel 13 kommt zudem in der Weise zu liegen, dass die Watte im richtigen Drehsinn von ihm abgezogen wird. Es ist ersichtlich, dass die Ausbildung der Transportlage somit in einer Weise ausgeführt ist, dass das Wattenende 35 und die Halteleiste 32 sich an beiden Maschinen 11 und 24 auf der Seite befinden, auf welcher das Wattenende einer Handhabung unterworfen ist. Die an beiden Wickelübergabestellen vorteilhafte Positionierung der Wickel 13 ist durch den Richtungswechsel der Transportschiene 14 um 180°, d. h. durch die Ausbildung der Transportanlage, bedingt.When the wadding roll 13a is grasped on the wadding machine 11, the operator is located to the left of the wrap 13a in the illustration in FIG. When the windings 13 have arrived at the sweeping section 24, the wad ends 35 according to FIG. 2 are on the left side of the wad windings 13. This is the page that the operator is on. Thus, the wadding end 35 is particularly easily accessible on this machine and can be easily inserted into the sweeping section 24 for further processing. The cotton roll 13 also comes to rest in such a way that the cotton is pulled off it in the correct direction of rotation. It can be seen that the transport position is thus designed in such a way that the wadding end 35 and the holding strip 32 are located on both machines 11 and 24 on the side on which the wadding end is subjected to handling. The advantageous positioning of the windings 13 at both winding transfer points is possible by changing the direction of the transport rail 14 by 180 °, ie. H. due to the design of the transport system.

In Figur 3 ist ein weiteres Ausführungsbeispiel einer erfindungsgemässen Anlage gezeigt. Dieses betrifft den Transport von Wattewickeln 36 von einer Kehrstrecke 24 zu Kämmaschinen 37. Es sind wiederum Transportschienen 38a, 38b, allgemein mit 38 bezeichnet, für den Transport der Wattewickel 36 und der leeren Hülsen vorhanden. Ausserdem ist an der Kehrstrecke 24 eine senkrecht auf- und abwärts bewegbare Tragschiene 41 und sind an den Kämmaschinen 37 senkrecht auf- und abwärts bewegbare Tragschienen 42 vorgesehen. Die Transportschienen 38 weisen keine, eine Richtungsänderung der Umlaufbahn bewirkenden, gebogenen Teile auf. Statt dessen sind allgemein mit 39 bezeichnete Schienenstücke 39a, 39b, 39c. 39d vorgesehen, von denen jedes um seine senkrechte Achse 40 schwenkbar ist. Mittels der Schienenstücke 39 ist wiederum eine in sich geschlossene, endlose Umlaufbahn vorhanden.FIG. 3 shows a further exemplary embodiment of a system according to the invention. This relates to the transport of cotton rolls 36 from a sweeping section 24 to combing machines 37. Transport rails 38a, 38b, generally designated 38, are again present for the transport of the cotton rolls 36 and the empty sleeves. In addition, a support rail 41 which can be moved vertically up and down is provided on the sweeping section 24 and support rails 42 which can be moved vertically up and down are provided on the combing machines 37. The transport rails 38 have no curved parts which cause a change in the direction of the orbit. Instead, rail sections 39a, 39b, 39c are generally designated 39. 39d is provided, each of which is pivotable about its vertical axis 40. By means of the rail pieces 39, a self-contained, endless orbit is again available.

Zum Transport der Wattewickel 36 werden diese in Gruppen von je drei Wickeln 36 mittels der Tragschiene 41 angehoben. Als Wickelübergabestelle kann ein Tisch 44 vorgesehen sein. Die drei von der Schiene 41 angehobenen Wattewickel 36 werden über die Transportschiene 38a auf das Schienenstück 39a aufgebracht, während dieses in der gezeichneten Lage mit seinem einen Ende an die von der Kehrstrecke 24 heranführende Transportschiene 38a anliegt. Daraufhin wird das Schienenstück 39a um 90° gedreht, so dass es mit dem Schienenstück 39b fluchtet. Nun werden die drei Wattewickel 36 auf das Schienenstück 39b bewegt. Falls diese Wickel 36 für die in Figur 3 unterste Kämmaschine 37 vorgesehen sind, werden sie zu deren Wickelübergabestelle gefahren und auf diese abgesetzt.To transport the wadding rolls 36, they are raised in groups of three rolls 36 each by means of the support rail 41. A table 44 can be provided as the winding transfer point. The three wadding rolls 36 raised by the rail 41 are applied to the rail section 39a via the transport rail 38a, while in the position shown, one end of this lies against the transport rail 38a leading from the sweeping section 24. The rail section 39a is then rotated through 90 ° so that it is aligned with the rail section 39b. Now the three cotton rolls 36 are moved onto the rail piece 39b. If these coils 36 are provided for the lowermost combing machine 37 in FIG. 3, they are moved to the winding transfer point and placed thereon.

Falls diese Gruppe von Wickeln 36 aber beispielsweise für die zweitunterste Kämmaschine 37 vorgesehen ist, wird das Schienenstück 39b um 90° gedreht und werden die Wickel 36 über die Transportschiene 38b auf das Schienenstück 39c gebracht. Vom letzteren. werden sie der zweituntersten Kämmaschine 42 zugeführt und auf deren Wickelübergabestelle abgesetzt.If, however, this group of windings 36 is provided for the second lowest combing machine 37, for example, the rail section 39b is rotated through 90 ° and the windings 36 are brought onto the rail section 39c via the transport rail 38b. From the latter. they are fed to the second lowest combing machine 42 and placed on the winding transfer point.

Bezüglich der anhand der Figuren 1 und 2 gemachten, das Wattenende 35 betreffenden Ausführungen sei festgestellt, dass auch in der Ausführungsform gemäss Figur 3 Träger 15 von der in Figur 2 gezeigten Art verwendet werden. Auch diese Träger 15 sind mit einer Halteleiste 32 versehen, welche beim Transport eines Wattewickels 36 an dessen äusserem Ende 35 anliegt. Es ist ersichtlich, dass in der Ausführungsform gemäss Figur 3 durch Drehen der Schienenstücke 39 um ihre Achse 40 in der einen oder in der entgegengesetzten Richtung die Wattenenden 35 stets auf die gewünschte Seite, d. h. auf die Seite, auf welcher sie einer Handhabung unterworfen sind, gebracht werden können. In diesem Beispiel wird dieses Resultat somit durch geeignete Wahl der Schwenkbereiche der Schienenstücke, d. h. ebenfalls durch eine geeignete Ausbildung der Transportanlage, erhalten.With regard to the statements made with reference to FIGS. 1 and 2 and relating to the cotton end 35, it should be noted that carriers 15 of the type shown in FIG. 2 are also used in the embodiment according to FIG. These carriers 15 are also provided with a holding strip 32 which bears against the outer end 35 of a cotton wrap 36 during transport. It can be seen that in the embodiment according to FIG. 3, by rotating the rail pieces 39 about their axis 40 in one direction or in the opposite direction, the wad ends 35 are always on the desired side, i. H. can be brought to the side on which they are subject to handling. In this example, this result is thus determined by a suitable choice of the swiveling ranges of the rail pieces, i. H. also obtained through a suitable training of the transport system.

Das Rückführen der leeren Hülsen erfolgt über die auf der linken Seite der Figur 3 gezeigten Transportschienen 38 und Schienenstücke 39.The empty sleeves are returned via the transport rails 38 and rail pieces 39 shown on the left side of FIG. 3.

Im Ausführungsbeispiel der Figur 3 werden die Wattewickel 36 den Kämmaschinen 37 in Gruppen von je drei Wickeln 41 zugeführt. Es versteht sich von selbst, dass statt dessen die in der Praxis gebraüchlichen Vierergruppen, oder auch andere Gruppengrössen vorgesehen sein können. In diesem Fall werden die Schienenstücke 39, die Tragschiene 41, der Tisch 44 und die Tragschienen 42 vorteilhafterweise zur Aufnahme von je vier Trägern, bzw. eine entsprechende Anzahl solcher Träger, vorgesehen.In the exemplary embodiment in FIG. 3, the cotton rolls 36 are fed to the combing machines 37 in groups of three rolls 41 each. It goes without saying that the groups of four or other group sizes that are common in practice can be provided instead. In this case, the rail pieces 39, the mounting rail 41, the table 44 and the mounting rails 42 are advantageously provided for accommodating four supports, or a corresponding number of such supports.
