Description

Die vorliegende Erfindung betrifft einen Drehteller für Faserbandablageeinrichtungen mit einem Bandkanal.The present invention relates to a turntable for Sliver storage devices with a band channel.

Bekannt ist aus der DE-PS 15 10 310 ein Drehteller zum Ablegen von Faserbändern in Spinnkannen mit einem Kanal, der das Faserband von einem oben und in der Drehachse des Drehtellers mündenden Eintrittsteil über eine im Grundriß kreisbogenförmige Krümmung zu einem untenliegenden, tangential zum Drehteller und etwa an dessen Umfang mündenden Austrittsteil führt. Der Kanal weist zwischen seinem Eintrittsteil und seinem Austrittsteil ein gerade und radial verlaufendes Zwischenstück auf. Insbesondere bei den modernen, sehr schnell laufenden Maschinen mit derartigen Drehtellern hat sich herausgestellt, daß derartige Kanäle zu ungünstigen und ungleichmäßigen Faserbandablagen führen.A turntable for storing is known from DE-PS 15 10 310 of slivers in sliver cans with a channel that holds the sliver from an opening at the top and in the axis of rotation of the turntable Entry part over a curvature in the shape of a circular arc to an underlying, tangential to the turntable and about leads to the periphery of the outlet part. The channel points a straight between its entry part and its exit part and radially extending intermediate piece. Especially with the modern, very fast running machines with such turntables it has been found that such channels are too unfavorable and uneven sliver storage.

Weiterhin ist aus der DE-PS 11 15 623 bekannt, daß der Kanal aus mindestens zwei kreisbogenförmig gebogenen Rohrkrümmern teleskopartig zusammengesetzt ist. Durch die teleskopartige Zusammensetzung der Krümmer kann der Verlauf des Kanals den verschiedenen Kannendurchmessern angepaßt werden. Die beiden Rohrkrümmer sind an ihre Verbindungsstelle mit geraden Enden versehen. Neben dem Nachteil des gerade verlaufenden Kanalteils wie in der oben erwähnten DE-PS 15 10 310 ergibt sich bei dieser Vorichtung noch zusätzlich der Nachteil, daß das Faserband über eine Rohrkrümmerkante geführt werden muß und einen veränderten Kanalquerschnitt durchläuft. Insbesondere bei schnellen Maschinen ist eine derartige Ausführung für eine hohe Genauigkeit bei der Ablage des Faserbandes und einer schonenden Behandlung des Faserbandes nicht gut geeignet. An der Kante können sich Ablagerungen bilden, die sich von Zeit zu Zeit ablösen und zu Ungleichmäßigkeiten in dem Faserband führen.Furthermore, it is known from DE-PS 11 15 623 that the channel at least two pipe elbows bent in a circular arc telescopically is composed. Due to the telescopic composition the manifold can change the course of the channel Can diameters can be adjusted. The two elbows are provide straight ends at their juncture. Next to the Disadvantage of the straight duct part as in that mentioned above DE-PS 15 10 310 results from this device additionally the disadvantage that the sliver has a pipe elbow edge must be performed and a changed channel cross-section goes through. Such is particularly the case with fast machines Version for high accuracy when laying the sliver and gentle treatment of the sliver is not well suited. Deposits can form on the edge detach itself from time to time and to irregularities in the Lead sliver.

Aufgabe der vorliegenden Erfindung ist es somit, insbesondere bei schnellen Vorichtungen zum Ablegen von Faserbändern in Spinnkannen durch eine entsprechende Gestaltung des Drehtellers und des Bandkanals eine in höchstem Maße gleichmäßige und faserbandschonende Ablage zu gewährleisten.The object of the present invention is therefore, in particular fast devices for placing slivers in sliver cans by appropriate design of the turntable and Ribbon channel is extremely uniform and gentle on the sliver To ensure storage.

Die Aufgabe wird gelöst durch die Merkmale des Anspruchs 1. Wird der Bandkanal aus einem Rohrstück mit zwei unmittelbar ineinander übergehenden Kreisbögen gebildet, so wirken auf das Faserband nur geringe Beschleunigungskräfte. Dadurch, daß kein gerades Stück zwischen den Kreisbögen angeordnet ist, wird das Faserband in dem Bandkanal schonend geführt, so daß praktisch keine bleibende Verformung nach der Ablage in der Spinnkanne in dem Faserband nachzuweisen ist. Diese gleichmäßige und schonende Ablage des Faserbandes ist bei den modernen, sehr genauen und schnellen Strecken und Karden von großer Bedeutung, um das zuvor hergestellte genaue Faserband bei der Ablage nicht wieder zu zerstören.The object is achieved by the features of claim 1 the band channel from a piece of pipe with two directly into one another transition arcs are formed, so act only on the sliver low acceleration forces. Because no straight piece is arranged between the arcs, the sliver in the Belt channel gently guided, so that practically no permanent deformation after being deposited in the sliver can in the sliver is. This even and gentle storage of the sliver is with the modern, very precise and fast routes and cards of great importance to the previously made exact Do not destroy the sliver again when it is put down.

Weisen beide Kreisbögen im wesentlichen gleiche Radien auf, so wirkt sich dies positiv auf die Beschleunigung des Faserbandes aus, da in diesem Fall des Faserbandes in großen Radien gewunden wird und somit geringe Umlenkkräfte auf das Faserband einwirken.If both arcs have essentially the same radii, so this has a positive effect on the acceleration of the sliver from because in this case the sliver is wound in large radii and thus act on the sliver with low deflection forces.

Weisen beide Kreisbögen an ihrem Übergang eine gemeinsame Tangente auf, so ist ein stetiger und kantenfreier Übergang der Kreisbögen gewährleistet.If both arcs have a common tangent at their transition on, there is a steady and edge-free transition of the arcs guaranteed.

Für die Faserbandablage hat sich in vorteilhafterweise herausgestellt, daß der Bandkanal ausschließlich aus Kreisbögen bestehen soll. Insbesonder das kreisbogenförmige Auslaufen des Bandkanals wirkt sich auf eine kraftarme Ablage des Faserbandes positiv aus.For the sliver storage, it has advantageously been found that that the band channel consist exclusively of arcs should. In particular the circular arc-shaped runout of the band channel has a positive effect on low-strength storage of the sliver.

Für eine Neigung der Ebenen, in denen die Kreisbögen angeordnet sind hat sich ein Winkel von 130° bewährt. Der Übergang des Bandkanals in die Horizontale erfolgt vorzugsweise unter einem Ablagewinkel von etwa 15°.For an inclination of the levels in which the arcs are arranged an angle of 130 ° has proven itself. The transition of the band channel in the horizontal direction is preferably at an angle of about 15 °.

In einer vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung ist der Bandkanal und/oder eine Abdeckung des Drehtellers aus Edelstahl gefertigt. Dadurch werden geringe Reibungswerte des Faserbandes erzielt, wodurch sowohl der Verschleiß des Drehtellers und des Bandkanals, als auch die Beschädigung des Faserbandes in vorteilhafterweise reduziert werden.In an advantageous embodiment of the device according to the invention is the band channel and / or a cover of the turntable made of stainless steel. This low friction values the sliver achieved, whereby both the wear of the Turntable and the band channel, as well as the damage to the sliver can advantageously be reduced.

Die Erfindung wird im folgenden anhand von Ausführungsbeispielen beschrieben. Es zeigt

  • Figur 1 einen Drehteller und eine Spinnkanne im Längsschnitt;
  • Figur 2 eine räumliche Darstellung der Bandkanalebenen;
  • Figuren 3 bis 5 eine Darstellung des Verlaufs der Mittellinie eines Bandkanals;
  • Figuren 6 bis 8 eine Darstellung eines Bandkanals.
    • The invention is described below on the basis of exemplary embodiments. It shows
  • Figure 1 shows a turntable and a spinning can in longitudinal section;
  • Figure 2 is a spatial representation of the band channel levels;
  • Figures 3 to 5 show the course of the center line of a band channel;
  • Figures 6 to 8 an illustration of a band channel.

    • Figur 1 zeigt einen Schnitt durch einen erfindungsgemäßen Drehteller 1 mit einem Bandkanal 2. Faserband tritt in den Bandkanal 2 in einem Einlauf 5 ein, durchläuft den Bandkanal 2 und tritt an einem Auslauf 6 aus dem Bandkanal 2 wieder aus. Der Einlauf 5 des Bandkanals 2 ist zentrisch in dem Drehteller 1 angeordnet. Eine Gußmasse 4 verbindet den Bandkanal 2 mit einem Tellerhalter 3. Dadurch ist gewährleistet, daß der Bandkanal 2 stets richtig positioniert ist und durch äußere Einflüsse seine Lage nicht verändert. Der Bandkanal 2 ist an seinem Auslauf 6 ebenfalls mit einer Gußmasse 8 fixiert. Durch die Gußmasse 8 wird gewährleistet, daß ein spaltfreier Übergang zwischen dem Bandkanal 2 und dem Drehteller 1 an der Unterseite des Drehtellers 1 gewährleistet ist. In einer erfindungsgemäßen Ausführung ist die Unterseite des Drehtellers 1 mit einer Abdeckung 7 versehen. Die Abdeckung 7 ist vorteilhafterweise aus Edelstahl hergestellt. Dadurch wird gewährleistet, daß zwischen dem in einer Spinnkanne 10 abgelegten Faserband und der Unterseite des Drehtellers 1 äußerst geringe Reibung und wenig Verschleiß auftritt. Darüber hinaus wird eine aufwendige Bearbeitung des Bodens des Drehtellers 1, insbesondere Schleifen und Spachteln des Aluminiumgußteiles Drehteller 1 vermieden. Auch muß weniger Sorgfalt beim Eingießen des Bandkanals 2 mit der Gußmasse 8 in den Drehteller 8 aufgewendet werden. Figure 1 shows a section through a turntable according to the invention 1 with a band channel 2. Sliver enters the band channel 2 in an inlet 5, passes through the band channel 2 and occurs an outlet 6 from the band channel 2 again. The inlet 5 of the Band channel 2 is arranged centrally in the turntable 1. A Casting compound 4 connects the band channel 2 to a plate holder 3. This ensures that the band channel 2 is always correctly positioned and does not change its position due to external influences. The band channel 2 is also at its outlet 6 with a Casting compound 8 fixed. The casting compound 8 ensures that a gap-free transition between the band channel 2 and the turntable 1 at the bottom of the turntable 1 is guaranteed. In an embodiment according to the invention, the underside of the Turntable 1 provided with a cover 7. The cover 7 is advantageously made of stainless steel. This ensures that between the deposited in a spinning can 10 Sliver and the bottom of the turntable 1 extremely low Friction and little wear occurs. In addition, a complex processing of the bottom of the turntable 1, in particular Grinding and filling of the cast aluminum turntable 1 avoided. Less care must also be taken when pouring the band channel 2 can be used with the casting compound 8 in the turntable 8.

    Je nach Faserbandablageeinrichtung und Spinnkanne 10 besteht zwischen Drehteller 1 und Spinnkanne 10 ein mehr oder weniger großer Abstand 9. Die erfindungsgemäße Vorrichtung bewirkt in vorteilhafter Weise, daß bei einem großen Abstand 9 kein Faserband über den Spinnkannenrand bei der Ablage hinausgeschleudert wird. Das Faserband wird vielmehr ohne großer radialer Geschwindigkeitskomponente in der Spinnkanne 10 abgelegt. Dadurch wird eine besonders gleichmäßige und geordnete Ablage des Faserbandes gewährleistet. Außerdem ist durch die geordnete Ablage auch ein günstiges Abziehen des Faserbandes aus der Kanne 10 sichergestellt. Dies wirkt sich insbesondere bei hohen Liefergeschwindigkeiten aus. Das Herausschleudern des Faserbandes ist insbesondere bei den ersten in der Spinnkanne 10 abgelegten Lagen des Faserbandes bei bekannten gattungsgemäßen Vorrichtungen zu beobachten.Depending on the sliver storage device and sliver can 10 there is between Turntable 1 and sliver can 10 a more or less large Distance 9. The device according to the invention has an advantageous effect Way that at a large distance 9 no sliver over the rim of the spinning can is flung out when it is placed on the shelf. The Rather, sliver is without a large radial speed component stored in the spinning can 10. This makes one special ensures even and orderly storage of the sliver. In addition, the orderly filing is also an inexpensive one Pulling the sliver from the can 10 ensured. This particularly affects at high delivery speeds. The sliver is thrown out particularly in the first in the sliver can 10 layers of the sliver to observe known generic devices.

    Eine Drehachse 11 des Drehtellers 1 ist eine Tangente an dem Einlaufbogen des Bandkanals 2. Durch Drehung des Drehtellers 1 und der Kanne 10 entsteht eine zykloidenförmige Ablage des Faserbandes in der Spinnkanne 10. Eine Mittellinie 14 des Bandkanals 2 verläuft von der Drehachse 11 am Einlauf 5 des Bandkanals 2 bis zum Auslauf 6 und stellt im wesentlichen die Verformung des Faserbandes beim Durchlaufen des Bandkanals 2 dar.An axis of rotation 11 of the turntable 1 is a tangent to the inlet bend of the band channel 2. By rotating the turntable 1 and the can 10 creates a cycloid-shaped deposit of the sliver in the spinning can 10. A center line 14 of the band channel 2 runs from the axis of rotation 11 at the inlet 5 of the band channel 2 to to the outlet 6 and essentially represents the deformation of the sliver when passing through the band channel 2.

    In Figur 2 ist die Mittellinie 14 des Bandkanals 2 in einem XYZ-Koordinatensystem dargestellt. Das Koordinatensystem ist dabei derart gelegt, daß der Einlauf 5 X und Y-Werte 0 hat und der Auslauf 6 Y- und Z-Werte 0 hat. Die Mittellinie 14 ist aus zwei Kreisbögen gebildet. Der erste Kreisbogen weist einen Mittelpunkt M1 auf und bezeichnet den Auslaufbogen. Der Einlaufbogen hat sein Zentrum in einem Mittelpunkt M2. Beide Bögen weisen einen gleichen Radius R auf. Durch den gleichen Radius R wird in einer vorteilhaften Ausgestaltung der Erfindung erreicht, daß das Faserband einer geringstmöglichen Belastung beim Durchlaufen des Bandkanals 2 ausgesetzt wird. Damit eine gleichmäßige Kraft auf das Faserband während des gesamten Durchlaufs durch den Bandkanal 2 herrscht, ist der Radius R möglichst groß zu wählen. Zur Erzielung möglichst großer Radien R ist es erfindungsgemäß vorteilhaft, wenn die Kreisbögen, die um die Mittelpunkt M1 und M2 geschlagen sind, unmittelbar ineinander übergehen. Die Kreisbögen weisen daher in einem Wendepunkt W eine gemeinsame Tangente T auf. Das Ende des Auslaufbogens 15 ist bestimmt durch einen festgelegten Ablageradius Ra, einen Ablagewinkel α1 der Austrittstangente zur Drehtellerbodenfläche, welche der Y-Achse des Koordinatensystems entspricht und durch eine Höhe H des Bandkanals 2. Zur Erreichung dieser vorgegebenen geometrischen Abmessungen ist eine Ebene E in welchem der Einlaufbogen 16 sich befindet zu einer Ebene A, in welcher sich der Auslaufbogen 15 befindet, um einen Winkel δ zueinander geneigt. Für einen raumsparenden Einbau des Drehtellers 1 in eine Faserbandablageeinrichtung hat sich als vorteilhaft erwiesen, wenn der Einlaufbogen 16 kürzer als der Auslaufbogen 15 ist. Durch die Neigung der Ebene E in einem Winkel α zur Y-Achse wird ein kurzer und für das Faserband beschleunigungsarmer Weg durch den Bandkanal 2 gewährleistet.In Figure 2, the center line 14 of the band channel 2 is in an XYZ coordinate system shown. The coordinate system is included such that the inlet has 5 X and Y values 0 and the outlet 6 Y and Z values have 0. The center line 14 is made up of two Arcs formed. The first arc has a center M1 and designates the outlet arch. The inlet elbow has to be Center in a center M2. Both arches have the same Radius R. By the same radius R is advantageous Embodiment of the invention achieves that the sliver the lowest possible load when passing through the belt channel 2 is suspended. So that an even force on the Sliver during the entire passage through the sliver channel 2 the radius R should be as large as possible. To achieve The largest possible radii R according to the invention are advantageous when the arcs that are struck around the midpoint M1 and M2 are to merge directly into one another. The arcs therefore have a common tangent T at a turning point W. on. The end of the outlet sheet 15 is determined by a fixed one Storage radius Ra, a storage angle α1 of the exit tangent to the surface of the turntable, which is the Y axis of the coordinate system corresponds and by a height H of the band channel 2. Zur Achieving these given geometric dimensions is one Level E in which the inlet bend 16 is located Level A, in which the outlet arch 15 is located, by one Angle δ inclined to each other. For a space-saving installation of the Turntable 1 in a sliver storage device has proven to be proven to be advantageous if the inlet bend 16 is shorter than that Outlet bend 15 is. Due to the inclination of the plane E at an angle α to the Y-axis becomes a short one and low acceleration for the sliver Guaranteed way through the band channel 2.

    Figur 3 zeigt eine Darstellung der Neigung der Ebene E des Einlaufbogens 16 zu der Ebene A des Auslaufbogens 15. Der Neigungswinkel δ beträgt in dem dargestellten Ausführungsbeispiel etwa 125°. Die Ebenen E und A schneiden sich in der Tangente T. Die Mittelpunkte M1 und M2 der beiden Kreisbögen des Bandkanals 2 liegen ebenfalls in der Ebene A bzw. E. Eine Ansicht B der Figur 3 ist in Figur 4 dargestellt. Figur 4 zeigt eine Darstellung der Mittellinie 14 des Bandkanals 2, bei welcher der Einlaufbogen 16 unverzerrt dargestellt ist. Der Einlaufbogen 16 weist den Radius R um den Mittelpunkt M2 auf. In dem vorliegenden Ausführungsbeispiel erstreckt sich der Einlaufbogen 16 über einen Winkel β1, der hier etwa 70° beträgt. Der Auslaufbogen 15 um den Mittelpunkt M1 ist in Figur 4 wegen der Neigung der Ebene A zu der Ebene E verzerrt dargestellt. Figur 4 zeigt neben dem Auslaufbogen 15 und dem Einlaufbogen 16 eine Gerade 12 vor dem Einlaufbogen 16. Die Gerade 12 ist bei dem Halbfertigprodukt aus fertigungstechnischen Gründen angeordnet.

In Figure 5, the outlet curve 15 is shown undistorted. The center line 14 of the band channel 2 has a radius R in the outlet arch 15 and the center point M1. Inlet bend 16 goes at the turning point W directly into the discharge curve 15. In the illustrated In the exemplary embodiment, the outlet bend 15 has an angle β2, which is approximately 127 °. From manufacturing technology Reasoning is in connection with the outlet sheet 15 for the semi-finished product a straight line 13 is arranged. Just as with line 12 is at the inlet bend 16 through the straight line 13 on the outlet bend 15 secure clamping of the preferably stainless steel tube that is used for the Formation of the band channel 2 is used, ensured in the bending tool. The straight line 13 becomes at the completion of the band channel 2 separated. The end of the outlet bend 15 is preferred boned.

    Figur 6 zeigt einen Bandkanal 2 in einer Ansicht radial zu dem Drehteller 1. Die beim Fertigprodukt abgetrennten Geraden 12 und 13 sind gestrichelt dargestellt. Es ist in Figur 6 deutlich zu erkennen, daß der Einlaufbogen 16 in dem Wendepunkt W mit dem Auslaufbogen 15 eine gemeinsame Tangente T bilden. Sowohl Einlaufbogen 16 als auch Auslaufbogen 15 weisen denselben Biegeradius R auf. Dies hat sich als besonders vorteilhaft erwiesen, da hierdurch die Beschleunigungskräfte auf das Faserband besonders gleichmäßig sind. Dadurch wird eine geordnete Abgabe des Faserbandes erzielt, ohne daß das Faserband bei der Ablage gegenüber seinem Zustand beim Einlauf in den Bandkanal 2 verändert wurde. Der Auslauf 6 ist derart ausgebildet, daß er mit dem Boden des Drehtellers 1 plan abschließt. Der Auslaufbogen 15 tritt in den Boden des Drehtellers 2 unter einem Ablagewinkel α1 ein. Als vorteilhaft hat sich für eine verzugsfreie Ablage des Faserbandes ein Ablagewinkel von 15° herausgestellt. Bei dem dargestellten Ausführungsbeispiel hat sich ein Radius R von etwa 80mm als besonders schonend für das Faserband ergeben.Figure 6 shows a band channel 2 in a view radially to the Turntable 1. The straight lines 12 and 13 are shown in dashed lines. It is clearly too in Figure 6 recognize that the inlet bend 16 at the turning point W with the Outlet arch 15 form a common tangent T. Both inlet bend 16 and outlet bend 15 have the same bending radius R on. This has proven to be particularly advantageous since thereby the acceleration forces on the sliver especially are even. This ensures an orderly delivery of the sliver achieved without the sliver opposite when filing its condition was changed when entering the band channel 2. The outlet 6 is designed such that it with the bottom of the Turntable completes 1 plan. The outlet sheet 15 enters the Bottom of the turntable 2 at a storage angle α1. As beneficial has opted for a warp-free storage of the sliver a shelf angle of 15 ° is highlighted. In the illustrated Embodiment has a radius R of about 80mm as special gentle on the sliver.
