Description

Die Erfindung betrifft eine Transportvorrichtung zum Bereitstellen von leeren Spulenhülsen an den Spinnstellen und zum Abtransportieren von vollen Spinnspulen von den Spinnstellen einer doppelseitigen Spinnmaschine, insbesondere einer Ringspinnmaschine, mit einem angetriebenen Transportmittel, das im Bereich der Spinnstelle angeordnet ist und das mit Mitnehmern für jeweils eine Spulenhülse oder eine Spinnspule aufnehmende Teller versehen ist, wobei die Mitnehmer die Teller in einem der Spindelteilung entsprechenden Abstand ausrichten.The invention relates to a transport device for providing empty bobbin tubes at the spinning stations and for removing full spinning bobbins from the spinning units of a double-sided spinning machine, in particular a ring spinning machine, with a driven transport means, which is arranged in the region of the spinning station and which has drivers for one bobbin tube or a plate accommodating a spinning bobbin is provided, the drivers aligning the plates at a distance corresponding to the spindle pitch.

Bei einer Vorrichtung der eingangs genannten Art (DE-A 37 12 027) sind auf beiden Seiten der Spinnmaschine Transportelemente vorgesehen, die zu einer hin- und hergehenden Bewegung angetrieben sind. Diese Transportelemente sind mit Mitnehmern ausgerüstet, die nur in einer Richtung die Teller mitnehmen, wodurch diese Teller zu den Spinnstellen ausgerichtet werden, damit sie für einen automatischen Spulenwechsel in einer korrekten Position stehen. Die Teller sind an einer U-förmig um die Spinnmaschine angeordneten Führungsbahn geführt, die an einem Maschinenende mit einer Einschleusestelle und einer Ausschleusestelle für die Teller verbunden ist.In a device of the type mentioned (DE-A 37 12 027), transport elements are provided on both sides of the spinning machine, which are driven for a reciprocating movement. These transport elements are equipped with drivers that only take the plates in one direction, whereby these plates are aligned with the spinning positions so that they are in the correct position for an automatic bobbin change. The plates are guided on a U-shaped guide track arranged around the spinning machine, which is connected at one end of the machine to an infeed point and an outfeed point for the plates.

Bei einer älteren, nicht vorveröffentlichten deutschen Patentanmeldung P 38 12 342.8 enthält die Transporteinrichtung ein Transportmittel, das als hochkant stehendes, endloses Stahlband ausgebildet ist, das mittels Führungen und/oder Umlenkrollen über beide Maschinenseiten der Spinnmaschine geführt wird. Die an dem Transportband angeordneten Mitnehmer transportieren mit Zapfen versehene Teller in den Bereich der Spinnstellen der Spinnmaschine,wobei die Teller auf einer Führungsbahn gleiten. Die Zapfen der Teller sind zur Aufnahme von Spulenhülsen oder Spinnspulen ausgebildet. Die Mitnehmer richten die Teller in einem der Spindelteilung entsprechenden Abstand aus, wodurch die Übergabe oder Übernahme von Spulenhülsen oder Spinnspulen mittels einer automatischen Wechseleinrichtung ermöglicht wird.In an older, unpublished German patent application P 38 12 342.8, the transport device contains a means of transport which is designed as an upright, endless steel belt which is guided by means of guides and / or deflection rollers over both machine sides of the spinning machine. The drivers arranged on the conveyor belt transport pegged plates into the area of the spinning positions of the spinning machine, the plates sliding on a guideway. The pins of the plates are designed to receive bobbin tubes or spinning bobbins. The drivers align the plates at a distance corresponding to the spindle pitch, which enables the transfer or takeover of bobbin tubes or spinning bobbins by means of an automatic changing device.

Bei einer anderen nicht vorveröffentlichten deutschen Patentanmeldung P 39 18 876.0 sind die Mitnehmer als Tragelement für die Teller ausgebildet, wobei an den Mitnehmern Aufnahmen für die Teller vorgesehen sind. Die Mitnehmer sind mit Führungselementen versehen, die gleitbeweglich in einer an den Längsseiten der Spinnmaschine angeordneten Führungsbahn geführt sind. Die Führungsbahn besitzt eine Leitkante, an der die Zapfen der Teller geführt sind.In another unpublished German patent application P 39 18 876.0, the drivers are designed as a support element for the plates, with receivers for the plates being provided on the drivers. The drivers are provided with guide elements which are slidably guided in a guide track arranged on the longitudinal sides of the spinning machine. The guideway has a leading edge on which the pins of the plates are guided.

Der Erfindung liegt die Aufgabe zugrunde, eine Transportvorrichtung der eingangs genannten Art so auszubilden, daß eine exakte Ausrichtung der Teller in einer Reihe gewährleistet ist.The invention has for its object to provide a transport device of the type mentioned so that an exact alignment of the plates is guaranteed in a row.

Diese Aufgabe wird bei einer gattungsgemäßen Transportvorrichtung dadurch gelöst, daß ein endloses, um den Bereich der Spinnstellen geführtes Transportmittel vorgesehen ist, daß die Mitnehmer mit Aussparungen versehen sind, die sich mit jeweils einer Aussparung des vorauslaufenden und des nachfolgenden Mitnehmers zu einer Aufnahme für jeweils einen Teller ergänzen, und daß die Mitnehmer mit Führungsflächen versehen sind, die in Transportrichtung auf gegenüberliegenden Seiten der Teller derart angeordnet sind, daß die Führungsflächen von zwei aufeinanderfolgenden Mitnehmern eine Einfassung für jeweils einen Teller bilden.This object is achieved in a generic transport device in that an endless means of transport guided around the area of the spinning stations is provided, that the drivers are provided with recesses, each with a recess of the leading and the subsequent driver to a receptacle for one Supplement plates, and that the drivers are provided with guide surfaces which are arranged in the transport direction on opposite sides of the plates so that the guide surfaces of two consecutive drivers form a border for one plate each.

Eine derart ausgebildete Transportvorrichtung besitzt einen besonders einfachen Aufbau, da separate Führungsbahnen für die Teller entfallen, da diese von den Mitnehmern getragen werden. Hierzu sind an den Mitnehmern Aussparungen vorgesehen, die die Teller in der Transportstellung aufnehmen und tragen. Weiterhin wird durch die als Tragelement ausgebildeten Mitnehmer erreicht, daß der Transport der Teller besonders sicher und reibungsarm erfolgt. Um eine exakte Ausrichtung der Teller zu erreichen, sind an den Mitnehmern Führungsflächen vorgesehen, die die Teller im Bereich der Spinnstellen in einer Reihe ausrichten. Ein Teller wird von den Führungsflächen zweier aufeinanderfolgender Mitnehmer positioniert, wobei diese Führungsflächen eine Einfassung für den Teller bilden. Das beim Erfindungsgegenstand vorgesehene endlose Transportmittel ist besonders wirtschaftlich, da nur eine Antriebseinheit erforderlich ist.A transport device designed in this way has a particularly simple construction, since there are no separate guideways for the plates, since these are carried by the drivers. For this purpose, recesses are provided on the drivers, which receive and carry the plates in the transport position. Furthermore, the carrier designed as a support element ensures that the plates are transported in a particularly safe and low-friction manner. In order to achieve an exact alignment of the plates, guide surfaces are provided on the carriers, which align the plates in a row in the area of the spinning positions. A plate is positioned by the guide surfaces of two successive drivers, these guide surfaces forming an enclosure for the plate. The endless means of transport provided in the subject matter of the invention is particularly economical since only one drive unit is required.

Bei einer vorteilhaften Ausgestaltung ist vorgesehen, daß die Führungsflächen einem Zapfen zugeordnet sind, der von dem jeweiligen Teller aufragt. Hierbei ist es vorteilhaft, wenn der Zapfen mit einem Kragen versehen ist, an dem die Führungsflächen aufeinanderfolgender Mitnehmer anliegen.In an advantageous embodiment it is provided that the guide surfaces are assigned to a pin which protrudes from the respective plate. It is advantageous here if the pin is provided with a collar against which the guide surfaces of successive drivers rest.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Führungsflächen jedes Mitnehmers derart zur Transportrichtung versetzt angeordnet sind, daß die in Transportrichtung vorauslaufende Führungsfläche bezüglich einer Umlenkstelle innen und die nachfolgende Führungsfläche außen liegt. Bezüglich der Transportrichtung wird somit der zwischen zwei Mitnehmern angeordnete Teller diagonal geführt, wodurch insbesondere quer zur Transportrichtung eine exakte und stabile Positionierung erfolgt.An advantageous development of the invention provides that the guide surfaces of each driver are arranged offset to the transport direction in such a way that the guide surface leading in the transport direction lies on the inside with respect to a deflection point and the subsequent guide surface is on the outside. With regard to the direction of transport, the plate arranged between two drivers is thus guided diagonally, as a result of which exact and stable positioning takes place, in particular, transversely to the direction of transport.

Es kann vorteilhaft vorgesehen sein, daß die Führungsflächen als Ausschnitt einer Zylinderfläche gestaltet sind,deren Durchmesser dem Durchmesser der Zapfen der Teller angepaßt ist. Hierdurch wird eine große Auflagefläche für die Führungsfläche geschaffen, wodurch einerseits ein fester Halt erzielt wird und wodurch andererseits keine Abnutzungserscheinungen auftreten. Außerdem können unterschiedlich große Teller eingesetzt werden, solange nur die Zapfen den gleichen Durchmesser aufweisen.It can advantageously be provided that the guide surfaces are designed as a section of a cylindrical surface, the diameter of which is adapted to the diameter of the pin of the plate. This creates a large contact surface for the guide surface, which on the one hand achieves a firm hold and on the other hand does not show any signs of wear. In addition, plates of different sizes can be used as long as only the pins have the same diameter.

Bei einer vorteilhaften Ausgestaltung ist vorgesehen, daß sich an die in Transportrichtung vorauslaufende Führungsfläche eine konvex gekrümmte Leitfläche anschließt, deren Abstand von dem Transportmittel beginnend an der Führungsfläche und quer zur Transportrichtung zunimmt. Hierdurch wird im Bereich einer Ausschleusestelle für die Teller ein selbsttätiger Austrag der Teller aus der Transportvorrichtung gewährleistet. Zusätzliche Mittel zum Ausschleusen der Teller sind somit nicht erforderlich.In an advantageous embodiment it is provided that a convexly curved guide surface adjoins the guide surface leading in the transport direction, the distance from the transport means increasing starting at the guide surface and transversely to the transport direction. This ensures automatic removal of the plates from the transport device in the area of a discharge point for the plates. Additional means for discharging the plates are therefore not necessary.

Bei einer vorteilhaften Ausgestaltung ist vorgesehen, daß die Mitnehmer mit im wesentlichen horizontalen Aufnahmeflächen für die Teller versehen sind.In an advantageous embodiment it is provided that the drivers are provided with essentially horizontal receiving surfaces for the plates.

Bei einer vorteilhaften Ausführungsform der Erfindung ist vorgesehen, daß die Mitnehmer mit Zapfen zur Aufnahme von vollen Spinnspulen oder leeren Spulenhülsen versehen sind. Hierdurch enfallen zusätzliche Einrichtungen zur Zwischenpositionierung von Spinnspulen oder Spulenhülsen beim Wechselvorgang.In an advantageous embodiment of the invention it is provided that the drivers are provided with pins for receiving full spinning bobbins or empty bobbin tubes. This eliminates the need for additional devices for the intermediate positioning of spinning bobbins or bobbin tubes during the changing process.

Hierbei sind im Bereich des Maschinenendgestells (14) der Ringspinnmaschine (10) eine Einund Ausschleusstelle (21, 22) für die Teller (20) vorgesehen. Die Zuführung der Teller (20) zu der Einschlesstelle (21) oder die Abführung der Teller (20) von der Ausschleusstelle (22) kann jeweils über ein Förderband (23, 24) erfolgen.With the transport device formed by the belt (15), plates (20) are guided to and from the spinning positions (11, 12) of the ring spinning machine (10). Here, in the area of the machine end frame (14) of the ring spinning machine (10), an entry and exit point (21, 22) for the plates (20) are provided. The plates (20) can be fed to the read-in point (21) or the plates (20) can be removed from the discharge point (22) via a conveyor belt (23, 24).

An dem hochkant angeordneten Band (15) der Transportvorrichtung sind mit Abstand zueinander Mitnehmer (25) befestigt, die gemäß Fig. 3 ein Fußteil (26) besitzen, das mittels eines Befestigungselementes (50) an dem Band (15) befestigt ist. Das Fußteil (26) des Mitnehmers (25) ist als Führungselement ausgebildet, das zusammen mit einem in der Zeichnung nicht dargestellten auf der gegenüberliegenden Seite des Transportbandes angeordneten Führungselement gleitbeweglich in einer nicht dargestellten Führungsbahn geführt ist. An der Führungsbahn stützen sich die Mitnehmer in horizontaler und vertikaler Richtung ab.2 shows the transport device in the area of the discharge point (22). Carriers (25) are fastened at a distance from one another on the upright arranged belt (15) of the transport device and, according to FIG. 3, have a foot part (26) which is fastened to the belt (15) by means of a fastening element (50). The foot part (26) of the driver (25) is designed as a guide element which, together with a guide element (not shown in the drawing) arranged on the opposite side of the conveyor belt, is guided so that it can slide in a guide path (not shown). The drivers are supported on the guideway in horizontal and vertical directions.

Das Oberteil der Mitnehmer (25) ist im Querschnitt U-förmig ausgebildet und besitzt eine untenliegende Tragplatte (27) und eine darüber angeordnete Führungsplatte (28), die über ein vertikal angeordnetes Verbindungsteil (29) miteinander verbunden sind. Wie insbesondere aus Fig. 3 hervorgeht, bilden die mit Abstand angeordneten Trag- und Führungsplatten (27, 28) benachbarter Mitnehmer (25) Aussparungen (30) zur Aufnahme der Grundplatte (31) eines dazwischenliegend aufgenommenen Tellers (20). Hierbei sind die Aufnahmeflächen (32) der Tragplatten (27) horizontal angeordnet. Die Höhe der an den Mitnehmern (25) vorgesehenen Aussparungen (30) ist so ausgebildet, daß die zwischenliegenden Teller (20) leicht zu- und ausgeführt werden können. Die als Tragelemente ausgebildeten Mitnehmer (25) ermöglichen einen sicheren und reibungsarmen Transport der Teller (20). Von den Führungsplatten (28) der Mitnehmer (25) ragen Zapfen (33) ab, die gleichartig mit den Zapfen (34) der Teller (20) ausgebildet sind. In der Transportstellung der Teller (20) sind die Zapfen (33) der Mitnehmer (25) und die Zapfen (34) der Teller (20) höhengleich angeordnet.The upper part of the drivers (25) is U-shaped in cross section and has a support plate (27) underneath and a guide plate (28) arranged above it, which are connected to one another via a vertically arranged connecting part (29). 3, the spaced support and guide plates (27, 28) of adjacent drivers (25) form recesses (30) for receiving the base plate (31) of a plate (20) accommodated in between. Here, the receiving surfaces (32) of the support plates (27) are arranged horizontally. The height of the recesses (30) provided on the drivers (25) is designed such that the plates (20) between them can be easily fed in and out. The carriers (25) designed as support elements enable the plates (20) to be transported safely and with little friction. Pins (33) protrude from the guide plates (28) of the drivers (25), which are designed in the same way as the pins (34) of the plates (20). In the transport position of the plates (20), the pins (33) of the drivers (25) and the pins (34) of the plates (20) are arranged at the same height.

Gemäß den Fig. 2 und 4 sind an der oberen Führungsplatte (28) der Mitnehmer (25) Führungsflächen (35, 36) vorgesehen, die in Transportrichtung in Richtung des Pfeiles (37) auf gegenüberliegenden Seiten des Mitnehmers (25) derart angeordnet sind, daß die Führungsflächen (35, 36) von zwei aufeinanderfolgenden Mitnehmern eine Einfassung für jeweils einen Teller (20) bilden. Die Führungsflächen (35, 36) der aufeinanderfolgenden Mitnehmer liegen an einem einen größeren Durchmesser aufweisenden Kragen (38) des Zapfen (34) des Tellers (20) an. Gegenüber der Transportrichtung in Richtung des Pfeiles (37) sind die Führungsflächen (35, 36) jedes Mitnehmers (25) derart versetzt angeordnet, daß die in Transportrichtung vorauslaufende Führungsfäche (35) bezüglich des Umlenkrades (18) innen und die nachfolgende Führungsfläche (36) außen liegt. Hierdurch wird der Teller (20) gleichsam diagonal geführt,wodurch insbesondere quer zur Transportrichtung eine gute Fixierung erreicht wird.2 and 4 on the upper guide plate (28) of the driver (25) guide surfaces (35, 36) are provided, which are arranged in the transport direction in the direction of arrow (37) on opposite sides of the driver (25), that the guide surfaces (35, 36) of two successive drivers form an enclosure for one plate (20). The guide surfaces (35, 36) of the successive drivers rest on a collar (38) of the pin (34) of the plate (20) with a larger diameter. Opposite the direction of transport In the direction of the arrow (37), the guide surfaces (35, 36) of each driver (25) are arranged offset such that the guide surface (35) leading in the transport direction lies on the inside with respect to the deflection wheel (18) and the following guide surface (36) lies on the outside. As a result, the plate (20) is guided, as it were, diagonally, as a result of which good fixation is achieved, in particular transversely to the direction of transport.

Die an den Mitnehmern (25) vorgesehenen Führungsflächen (35, 36) richten die von der Transportvorrichtung transportierten Teller (20) im Bereich der Spinnstellen (11, 12) der Ringspinnmaschine (10) in einer Reihe aus. Hierdurch wird die Übernahme von vollen Spinnspulen oder die Übergabe von leeren Spulenhülsen mittels einer in der Zeichnung nicht dargestellten automatischen Wechseleinrichtung verbessert, da die Zapfen (34) der Teller (20) und die Zapfen (33) der Mitnehmer (25) in einer geraden Linie angeordnet sind.The guide surfaces (35, 36) provided on the drivers (25) align the plates (20) transported by the transport device in a row in the region of the spinning positions (11, 12) of the ring spinning machine (10). This improves the takeover of full spinning bobbins or the transfer of empty bobbin tubes by means of an automatic changing device, not shown in the drawing, since the pins (34) of the plates (20) and the pins (33) of the drivers (25) are in a straight line are arranged.

Die an den Seitenflächen der Führungsplatte (28) jedes Mitnehmers (25) vorgesehenen Führungsflächen (35, 36) sind als Ausschnitt einer Zylinderfläche gestaltet, deren Durchmesser dem Kragen (38) des Tellerzapfens (34) angepaßt ist. Somit ist die Transportvorrichtung in der Lage, Teller (20) unabhängig vom Durchmesser der Grundplatte (31) exakt auszurichten.The guide surfaces (35, 36) provided on the side surfaces of the guide plate (28) of each driver (25) are designed as a section of a cylindrical surface, the diameter of which is adapted to the collar (38) of the plate pin (34). The transport device is thus able to align plates (20) exactly regardless of the diameter of the base plate (31).

An den Mitnehmern (25) der Transportvorrichtung ist eine konvex gekrümmte Leitfläche (40) vorgesehen,deren Ausbildung besonders deutlich aus dem in Fig. 2 im Bereich des Umlenkrades (18) angeordneten Mitnehmers (25) hervorgeht, der keinen Teller (20) transportiert. Die Leitfläche (40) schließt sich an die in Transportrichtung vorauslaufende konkave Führungsfläche (35) an. Demgemäß ist die Führungsplatte (28) des Mitnehmers (25) an ihrer Vorderkante S-förmig ausgebildet. Hierbei nimmt der Abstand von dem Band (15) beginnend an der Führungsfläche (35) und quer zur Transportrichtung (37) zu. Somit wird erreicht, daß im Bereich der Ausschleusstelle (22) der Transportvorrichtung der mit seinem Kragen (38) an der Leitfläche (40) entlanggleitende Teller (20) ausgeschleust wird. Die im Bereich der Leitfläche (40) vergrößert ausgebildete Aufnahmefläche (32) der Tragplatte (27) stützt hierbei den Teller (20) so lange ab, bis er von Leitschienen (41, 42) einer an das Band (15) angrenzenden Ausschleuseinrichtung (43) geführt und von dem Förderband (24) aufgenommen wird.A convexly curved guide surface (40) is provided on the carriers (25) of the transport device, the design of which is particularly clear from the carrier (25) arranged in the region of the deflection wheel (18) in FIG. 2, which does not transport a plate (20). The guide surface (40) adjoins the concave guide surface (35) leading in the transport direction. Accordingly, the guide plate (28) of the driver (25) is S-shaped at its front edge. The distance from the belt (15) increases starting from the guide surface (35) and transversely to the transport direction (37). This ensures that in the area of the discharge point (22) of the transport device the plate (20) which slides along with its collar (38) along the guide surface (40). The receiving surface (32) of the support plate (27), which is enlarged in the area of the guide surface (40), supports the plate (20) until it is guided by guide rails (41, 42) of a discharge device (43) adjacent to the belt (15) ) guided and picked up by the conveyor belt (24).

In Fig. 4 ist die Transportvorrichtung im Bereich der Einschleusstelle (21) gezeigt. Eine prinzipiell gleichartig wie die Ausschleuseinrichtung (43) ausgebildete Einschleuseinrichtung (44) besitzt Leitschienen (45, 46), auf denen die Teller (20) herangeführt werden. Das mit der Einschleuseinrichtung (44) verbundene Förderband (23) übt einen Druck auf die bereitstehenden Teller (20) aus. Somit wird ein an vorderster Stelle bereitstehender Teller (20) zwischen zwei aufeinanderfolgende Mitnehmer (25) geführt und zwischen diesen aufgenommen. Während einer kurzen Übergangsphase gleitet der Teller (20) einerseits auf der äußeren Leitschiene (46) der Einschleuseinrichtung (44) und auf den Aufnahmeflächen (32) der Tragplatten (27) der Mitnehmer (25). Bei weiterer Drehung des Umlenkrades (19) wird schließlich der Kragen (38) des Tellerzapfens (34) zwischen den Führungsflächen (35, 36) aufeinanderfolgender Mitnehmer (25) fixiert.4 shows the transport device in the area of the entry point (21). A sluice device (44) which is basically of the same design as the discharge device (43) has guide rails (45, 46) on which the plates (20) are brought up. The conveyor belt (23) connected to the infeed device (44) exerts pressure on the plates (20) that are ready. A plate (20) standing at the front is thus guided between two successive drivers (25) and received between them. During a short transition phase, the plate (20) slides on the one hand on the outer guide rail (46) of the infeed device (44) and on the receiving surfaces (32) of the carrier plates (27) of the drivers (25). When the deflection wheel (19) is turned further, the collar (38) of the plate pin (34) is finally fixed between the guide surfaces (35, 36) of successive drivers (25).
