Description

Die Erfindung betrifft eine Transportvorrichtung nach dem Ober­begriff des Patentanspruches 1.The invention relates to a transport device according to the preamble of claim 1.

Derartige Transportvorrichtungen zum selbsttätigen Auswechseln der vollen Spulen gegen leere Spulenhülsen werden insbesondere bei doppelseitigen Spinnmaschinen eingesetzt. Bei einer bekann­ten Vorrichtung dieser Art (DE-PS 502 149) ist an jeder Maschi­nenseite oberhalb des Spindelkastens jeweils ein Transportband angeordnet, das teilweise als Kette und teilweise als Seil aus­gebildet ist.Das Transportband wird um eine Umlenkrolle geführt und durch Trommeln in Bewegung gesetzt, auf welche an den Enden der Kette angreifende Seile auflaufen. An dem Transportband sind Hohlzylinder angeordnet, die zum einen beidseitig geöffnet und zum anderen an einer Seite mit einem Deckel versehen sind. Die verschiedenen Hohlzylinder sind abwechselnd an der Kette befestigt und dienen zum Abtransport der vollen Spulen und zur Zuführung der leeren Spulenhülsen. Das Transportband mit den Hohlzylindern absolviert während der Wechselvorgänge eine os­zillierende Bewegung, wodurch in Folge der ungenutzten Rückfüh­rung bei großen Maschinen lange Wechselintervalle entstehen.Such transport devices for automatically replacing the full bobbins with empty bobbin tubes are used in particular in double-sided spinning machines. In a known device of this type (DE-PS 502 149), a conveyor belt is arranged on each machine side above the headstock, which is partly designed as a chain and partly as a rope. The conveyor belt is guided around a deflection roller and set in motion by drums, on which ropes attacking at the ends of the chain run. Hollow cylinders are arranged on the conveyor belt, which are opened on both sides and are provided with a cover on one side. The various hollow cylinders are alternately attached to the chain and serve to remove the full bobbins and to feed the empty bobbin tubes. The conveyor belt with the hollow cylinders undergoes an oscillating movement during the change processes, which results in long change intervals as a result of the unused return on large machines.

Bei einer anderen bekannten Vorrichtung (JP-PS 47-39 740) ist zum Transport der Spulenhülsen eine Endloskette und zum Trans­ port der Spinnspulen ein Förderband vorgesehen. Die vollen Spu­len werden durch eine Vorrichtung angehoben und auf das Förder­band abgelegt. Die gleiche Vorrichtung setzt die leeren Spulen­hülsen auf die Spindeln auf. Durch die beiden Transportbänder ist die bekannte Vorrichtung einerseits aufwendig im Aufbau und andererseits wenig automatisierungsfreundlich.In another known device (JP-PS 47-39 740) is an endless chain for transporting the bobbin tubes and for trans A conveyor belt is provided for the spinning bobbins. The full bobbins are lifted by a device and placed on the conveyor belt. The same device places the empty spool sleeves on the spindles. Due to the two conveyor belts, the known device is complex on the one hand and not very easy to automate on the other.

In der (CH-PS 545 866) wird an jeder Maschinenseite jeweils ein endloses Transportband vorgeschlagen, das als Riemen oder Gurt ausgebildet ist und oberhalb der Spindeln angeordnet ist. Die endlosen Transportbänder werden jeweils mittels zweier Umlenk­rollen umgelenkt und von einer Antriebseinheit angetrieben. An dem Transportband sind gabelförmige Mitnehmer im Abstand der Spindeln vorgesehen. Zum Wechseln der vollen Spulen gegen leere Spulenhülsen wird das Transportband in Richtung der Spindeln geschwenkt, so daß die Mitnehmer in Höhe der vollen Spulen an­geordnet sind. Durch die Drehbewegung des Transportbandes grei­fen die Mitnehmer in die Spulen ein. Mit einer Hebevorrichtung werden die Spulen angehoben und während einer Rückwärtsbewegung des Transportbandes im Bereich einer Führungsrolle ausgetragen. Gleichzeitig werden bei dieser Drehbewegung des Transportbandes die leeren Spulenhülsen über die Spindeln gebracht und an­schließend abgesenkt. Während des Wechselvorganges ist somit das Transportband verschiedenen Drehrichtungen unterworfen. Der Wechsel der Spulen ist bei dieser bekannten Vorrichtung zeit­aufwendig, da ungenutzte Rückführungen des Transportbandes auf­treten. Da jeder Maschinenseite ein Transportband zugeordnet ist, sind zwei Antriebseinheiten und zwei Vorrichtungen zur Zu­führung und Abnahme der Spinnspulen oder Spulenhülsen erforder­lich. Hierdurch ist an diese bekannte Vorrichtung aufwendig im Aufbau und wenig automatisierungsfreundlich.In (CH-PS 545 866) an endless conveyor belt is proposed on each machine side, which is designed as a belt or belt and is arranged above the spindles. The endless conveyor belts are each deflected by means of two deflection rollers and driven by a drive unit. Fork-shaped drivers are provided on the conveyor belt at a distance from the spindles. To change the full bobbins against empty bobbin tubes, the conveyor belt is pivoted in the direction of the spindles so that the drivers are arranged at the level of the full bobbins. The drivers engage in the coils due to the rotary movement of the conveyor belt. The bobbins are raised with a lifting device and carried out in the region of a guide roller during a backward movement of the conveyor belt. At the same time, during this rotary movement of the conveyor belt, the empty bobbin tubes are brought over the spindles and then lowered. During the changing process, the conveyor belt is thus subjected to different directions of rotation. The change of the spools in this known device is time-consuming since unused returns of the conveyor belt occur. Since a conveyor belt is assigned to each machine side, two drive units and two devices for feeding and removing the spinning bobbins or bobbin tubes are required. As a result, this known device is complex in construction and not very easy to automate.

Der Erfindung liegt die Aufgabe zugrunde, eine Transportvor­richtung der eingangs genannten Art so auszubilden, daß der Aufbau vereinfacht und für eine weitgehende Automatisierung ge­eignet ist.The invention has for its object to provide a transport device of the type mentioned that the structure is simplified and suitable for extensive automation.

Diese Aufgabe wird bei einer gattungsgemäßen Transportvorrich­tung durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Ein über beide Maschinenseiten geführtes Band, das als flexibles Stahlband ausgebildet ist und an dem Mitnahmemittel für die Spulenhülsen und Spinnspulen angeordnet sind, benötigt nur eine Antriebseinheit. Weiterhin ist nur eine Vorrichtung zur Ab- und Zuführung der Spinnspulen und Spulenhülsen erfor­derlich. Hierdurch wird die Automatisierung wesentlich erleich­tert. Gleichzeitig treten bei der erfindungsgemäßen Transport­vorrichtung keine ungenutzten Rückführungen des Bandes auf. Die Verwendung eines flexiblen Stahlbandes ist besonders kostengün­stig und wartungsarm. Durch die Verwendung von nur einem Band wird insgesamt der Aufbau der Transportvorrichtung vereinfacht.This object is achieved in a generic transport device by the characterizing features of claim 1. A belt guided over both machine sides, which is designed as a flexible steel belt and on which driving means for the bobbin tubes and spinning bobbins are arranged, only requires one drive unit. Furthermore, only one device for removing and feeding the spinning bobbins and bobbin tubes is required. This makes automation much easier. At the same time, no unused returns of the belt occur in the transport device according to the invention. The use of a flexible steel band is particularly inexpensive and requires little maintenance. The use of only one belt simplifies the overall structure of the transport device.

Das mittels Führungen und/oder Umlenkrollen über beide Maschi­nenseiten geführte Band kann mit beliebiger Länge ausgeführt sein. Somit kann die erfindungsgemäße Transportvorrichtung auch bei sehr großen Maschinenlängen eingesetzt werden.The belt which is guided over both machine sides by means of guides and / or deflection rollers can be of any length. The transport device according to the invention can thus also be used with very large machine lengths.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further advantages and features of the invention emerge from the subclaims.

In einer vorteilhaften Ausführungsform der Erfindung wird das Stahlband hochkant stehend in Führungen geführt, die an hori­zontal liegenden Trägern vorgesehen sind, die an beiden Maschi­nenseiten der Spinnmaschine angeordnet sind.In an advantageous embodiment of the invention, the steel strip is guided in an upright position in guides which are provided on horizontal supports which are arranged on both machine sides of the spinning machine.

Das Band wird vorzugsweise an seinen Rändern in schlitzartig ausgebildeten Führungen gleitbeweglich gehalten, die an den Trägern in einer Ebene übereinanderliegend angeordnet sind. Die Träger sind näherungsweise mit L-förmigem Querschnitt ausgebil­det, wobei an dem Vertikalschenkel die schlitzartigen Führungen angeordnet sind und der Horizontalschenkel mit einer Gleitfläche ausgebildet ist.The band is preferably slidably held at its edges in slot-like guides which are arranged one above the other on the carriers in one plane. The carriers are approximately formed with an L-shaped cross section, the slot-like guides being arranged on the vertical leg and the horizontal leg being formed with a sliding surface.

Die Mitnahmemittel am Band können als Aufnahmen ausgebildet sein, die auf der Gleitfläche gleitbeweglich aufliegen und ei­nen Zapfen zur Befestigung der Spinnspule und der Spulenhülse besitzen. Die Aufnahmen sind vorzugsweise aus Kunststoff herge­stellt. Die Befestigung am Stahlband kann mittels einer Schrau­be oder nur durch Einhängen in ein Langloch erfolgen. Diese Ausbildungsform der erfindungsgemäßen Transportvorrichtung ist besonders einfach, da nur wenige Teile erforderlich sind.The entraining means on the belt can be designed as receptacles which rest on the sliding surface in a sliding manner and have a pin for fastening the spinning bobbin and the bobbin tube. The recordings are preferably made of plastic. The attachment to the steel belt can be done with a screw or just by hanging it in an elongated hole. This embodiment of the transport device according to the invention is particularly simple since only a few parts are required.

Eine andere Ausbildungsform des Erfindungsgegenstandes sieht an dem Band Mitnehmer zum Transport von auf Gleitflächen laufenden Tellern vor, wobei die Mitnehmer Aufnahmeflächen aufweisen, die den Tellern angepaßt sind und diese teilweise umschließen. Der­artige Teller sind in der Textiltechnik bekannt und kommen als Aufnahmen für Spinnspulen und Spulenhülsen in vielfältiger Wei­se zum Einsatz. Diese Ausbildungsform der erfindungsgemäßen Transportvorrichtung ist deshalb besonders für die Kombination mit anderen Transportsystemen geeignet. Beispielsweise können die Teller im Bereich einer Umlenkrolle auf ein an die Trans­portvorrichtung angrenzendes Förderband ausgeschleust werden.Another embodiment of the subject matter of the invention provides drivers for the transport of plates running on sliding surfaces on the belt, the drivers having receiving surfaces which are adapted to the plates and partially enclose them. Such plates are known in textile technology and are used in various ways as receptacles for spinning bobbins and bobbin tubes. This embodiment of the transport device according to the invention is therefore particularly suitable for combination with other transport systems. For example, the plates in the area of a deflection roller can be discharged onto a conveyor belt adjacent to the transport device.

Es ist besonders vorteilhaft, daß bei der erfindungsgemäßen Vorrichtung nur eine Greifvorrichtung für die Abnahme bzw. Zu­führung der Spinnspulen und der Spulenhülsen nötig ist. Neben der Vereinfachung des Aufbaus wird hierdurch ein besonders ho­her Grad an Automatisierung möglich.It is particularly advantageous that in the device according to the invention only one gripping device is required for removing or feeding the spinning bobbins and the bobbin tubes. In addition to simplifying the structure, this enables a particularly high degree of automation.

Insbesondere, wenn die Greifvorrichtung (4) mit in due Hülsen der Spinnspulen (7′) eingreifenden Greifzapfen versehen sind, ist es notwendig, daß die Hülsen möglichst exakt geführt sind. Es kann dann vorkommen, daß die Hülsen mit einem einen Kraft­schluß verursachenden Sitz auf die Zapfen (10′) der Teller (10) aufgesteckt sind. Um zu verhindern, daß bei einem Abziehversuch die Teller (10) mit abgehoben werden, wird bei einer Ausgestal­tung der Erfindung vorgesehen, daß die Mitnehmer (9) und/oder der Träger (5) mit die Teller (10) übergreifenden Elementen versehen sind, die die Form von sich oberhalb der Teller (10) befindlichen Laschen haben können.In particular, if the gripping device (4) is provided with gripping pins engaging in the sleeves of the spinning bobbins (7 '), it is necessary that the sleeves are guided as precisely as possible. It can then happen that the sleeves are attached to the pin (10 ') of the plate (10) with a seat causing a force fit. In order to prevent the plates (10) from being lifted off during a pull-off attempt, it is provided in one embodiment of the invention that the drivers (9) and / or the carrier (5) are provided with elements which overlap the plates (10), which can have the shape of tabs located above the plate (10).
