Description

Die Erfindung betrifft eine Fadenverlegevorrichtung zur Verwendung bei der Herstellung einer mit einem Garn bewickelten, bevorzugt als Kreuzspule ausgebildeten Garnspule, mit einer mittels eines Antriebes um eine Drehachse rotierbaren Verlegetrommel mit einem fadenführenden Schlitz auf der Zylinderoberfläche der Verlegetrommel, wobei die Drehachse von einer Welle mit zwei Wellenenden ausgebildet wird.The invention relates to a yarn laying device for use in the production of a wound with a yarn, preferably designed as a cheese package, with a rotatable by means of a drive about a rotation axis laying drum with a thread-guiding slot on the cylinder surface of the laying drum, wherein the axis of rotation of a shaft with two Shaft ends is formed.

Beim Herstellen von Garnspulen muss zum Erreichen einer gleichmäßigen Bewicklung der Faden des aufzuwickelnden Garns über der Länge der Längsachse, also dem Hub der Garnspule, der Garnspule hin- und herbewegt werden, so dass eine Changierbewegung ausgeführt wird. Letzteres wird als Verlegen bezeichnet. Dazu ist es z. B. aus der US 3523652 A bekannt, so genannte Verlegetrommeln zu verwenden. Die Verlegetrommel ist dabei mit ihrer Drehachse parallel zur Längsachse der Garnspule im Fadenlauf vor der Garnspule in der Fadenverlegevorrichtung angeordnet. Der Faden ist in einem zick-zack-förmigen Schlitz in der zylinderartigen Oberfläche (Zylinderoberfläche) der Verlegetrommel geführt und läuft die Drehachse ausbildende Welle tangierend durch die Verlegetrommel hindurch. Der Faden liegt also an der Welle an. Durch die Führung des Fadens in dem Schlitz wird der Faden über der Länge der Längsachse der Garnspule hin- und herbewegt, soweit der Schlitz sich in Längsrichtung der Längsachse entsprechend erstreckt. Die Art der Aufspulung, d.h. die Aufspulcharakteristik, ist also über die Form des Schlitzes festgelegt. Die Welle ist dabei an beiden Wellenenden an der Fadenverlegevorrichtung, üblicherweise über Kugellager, gelagert. Es wird also eine beidseitige Lagerung der Verlegetrommel verwendet.When producing bobbins to achieve a uniform winding of the yarn to be wound yarn over the length of the longitudinal axis, ie the stroke of the yarn package, the yarn package must be reciprocated so that a traversing movement is performed. The latter is called laying. This is z. B. from the US 3523652 A known to use so-called laying drums. The laying drum is arranged with its axis of rotation parallel to the longitudinal axis of the yarn package in the yarn path in front of the yarn package in the yarn laying device. The thread is guided in a zig-zag-shaped slot in the cylinder-like surface (cylinder surface) of the laying drum and running the axis of rotation forming shaft tangentially through the laying drum therethrough. The thread is thus applied to the shaft. By guiding the yarn in the slot, the yarn is reciprocated over the length of the longitudinal axis of the yarn package as far as the slot extends correspondingly in the longitudinal direction of the longitudinal axis. The type of winding, ie the Aufspulcharakteristik is thus determined by the shape of the slot. The shaft is mounted on both shaft ends on the thread laying device, usually via ball bearings. So it is a two-sided storage of the laying drum used.

Dadurch, dass der Faden an der Welle anliegt, entstehen Ablagerungen des entstehenden Fadenabriebs innerhalb der Verlegetrommel, die die Reibung an der Welle erhöhen können. Letzteres erhöht die Wahrscheinlichkeit von Fadenbrüchen, die wiederum zu Fadenaufwicklungen an der Verlegetrommel führen können. Zur Reinigung der Verlegetrommel sind deshalb Fenster in der Zylinderoberfläche der Verlegetrommel vorgesehen. Bei kleinen Hüben, d.h. kurzer Längsachse der Verlegetrommel von ca. 1 bis 6 Zoll Länge, ist es jedoch schwierig, eine Reinigung durch derartige Fenster vorzunehmen. Weiter führt das Rotieren derartiger Fenster zu einer erheblichen Verletzungsgefahr, so dass ein Schutzgehäuse vorzusehen ist.
Die beidseitige Lagerung der Verlegetrommel führt zu erheblichem Montageaufwand bei einer Demontage der Verlegetrommel zu deren Reinigung oder zum Auswechseln der Verlegetrommel, um eine Verlegetrommel mit einer anderen Aufspulcharakteristik zu verwenden. Außerdem müssen unterschiedliche Grundbauteile der Verlegetrommel für verschiedene Hübe verwendet werden, da immer die gesamte Länge zwischen den Montagepunkten der Welle an der Fadenverlegevorrichtung zu deren beidseitiger Lagerung überbrückt werden muss.The fact that the thread rests against the shaft, deposits of the resulting thread abrasion arise within the laying drum, which can increase the friction on the shaft. The latter increases the likelihood of thread breaks, which in turn can lead to thread windings on the laying drum. To clean the laying drum windows are therefore provided in the cylinder surface of the laying drum. For small strokes, ie short longitudinal axis of the laying drum of about 1 to 6 inches in length, it is difficult to perform a cleaning through such windows. Furthermore, the rotation of such windows leads to a considerable risk of injury, so that a protective housing is provided.
The two-sided storage of the laying drum leads to considerable installation effort in disassembly of the laying drum for their cleaning or to replace the laying drum to use a laying drum with a different Aufspulcharakteristik. In addition, different basic components of the laying drum must be used for different strokes, as always the entire length between the mounting points of the shaft must be bridged to the thread laying device to the two-sided storage.

Bei einem Produktionswechsel muss die Trommel gereinigt werden, damit beispielsweise ein helles Garn nicht von den Ablagerungen (Flusen, Avivage etc.) des vorherigen Garnes verunreinigt wird.During a production change, the drum must be cleaned so that, for example, a light yarn is not contaminated by the deposits (lint, softening etc.) of the previous yarn.

Es kann auch geschehen, dass beim Umspulen der Faden zwischen der Trommel und der Spule (Wickelkörper) reißt, der Faden durch die Avivage auf der Trommelachse kleben bleibt und dadurch auf dieselbe aufgewickelt wird. Ein solcher "Trommelwickel" muss nun mit einer Schere oder Messer geschnitten werden. Konventionell (mit den Fenstern in den die Zylinderoberfläche ausbildenden Trommelblechen) ist dies nur sehr mühsam möglich, wegen schlechter Zugänglichkeit. Oftmals muss der ganze Trommelhalter dazu herausgenommen, demontiert und gereinigt werden.
Zwecks Reinigung gibt es auf den Trommelblechen bekannter Verlegetrommeln entweder Schlitze in den Flügeln oder Löcher in den Flanschteilen. Diese sind äußerst gefährlich und müssen mit einer Türe geschützt werden.It can also happen that when rewinding the thread between the drum and the bobbin (bobbin) ruptures, the thread sticks through the lubricant on the drum axis and is thereby wound on the same. Such a "drum wrap" must now be cut with scissors or knives. Conventionally (with the windows in the drum surface forming the cylinder surface), this is very difficult because of poor accessibility. Often the whole drum holder has to be taken out, disassembled and cleaned.
For the purpose of cleaning, there are either slots in the wings or holes in the flange parts on the drum plates of known laying drums. These are extremely dangerous and must be protected with a door.

Der Erfindung liegt die Aufgabe zugrunde, eine Fadenverlegevorrichtung bereitzustellen, welche Nachteile des Standes der Technik vermeidet, wobei insbesondere ein rascher Wechsel der Aufspulcharakteristik möglich sein soll.The invention has for its object to provide a yarn laying device, which avoids the disadvantages of the prior art, in particular, a rapid change of Aufspulcharakteristik should be possible.

Diese Aufgabe wird durch die Fadenverlegevorrichtung des unabhängigen Anspruchs gelöst. Die abhängigen Ansprüche stellen bevorzugte Ausführungsformen der Erfindung dar.This object is achieved by the thread laying apparatus of the independent claim. The dependent claims represent preferred embodiments of the invention.

Eine erfindungsgemäße Fadenverlegevorrichtung zur Verwendung bei der Herstellung einer mit einem Garn bewickelten, bevorzugt als Kreuzspule ausgebildeten Garnspule, weist eine mittels eines Antriebes um eine Drehachse rotierbare Verlegetrommel mit einem fadenführenden Schlitz auf der Zylinderoberfläche der Verlegetrommel auf. Die Drehachse wird von einer Welle mit zwei Wellenenden ausgebildet.
Eines der Wellenenden ist als Montagewellenende derart ausgebildet, dass die Welle mit dem Montagewellenende an der Fadenverlegevorrichtung montiert ist. Das zweite Wellenende ist als freies Wellenende ausgebildet. Die Welle ist also nur einseitig gelagert, so dass eine einseitige Lagerung, d.h. eine einseitige Einspannung der Verlegetrommel ausgebildet ist.
Die Welle kann dabei z.B. direkt von einem Elektromotor in Verlängerung der Motorwelle des Elektromotors ausgebildet sein oder es kann eine drehbare Lagerung der Welle vorgesehen sein, so dass der Antrieb z.B. als Riemenantrieb ausgebildet sein kann. Die Welle kann auch starr montiert sein, so dass lediglich die Verlegetrommel auf der Welle rotierbar gelagert ist.A thread laying device according to the invention for use in the production of a yarn package wound with a yarn, preferably a cross-wound bobbin, has a laying drum rotatable about a rotation axis by means of a drive with a thread-guiding slot on the cylinder surface of the laying drum. The axis of rotation is formed by a shaft with two shaft ends.
One of the shaft ends is formed as a mounting shaft end such that the shaft is mounted with the mounting shaft end on the thread laying device. The second shaft end is designed as a free shaft end. The shaft is thus mounted only on one side, so that a one-sided storage, ie a one-sided clamping of the laying drum is formed.
The shaft can be formed, for example directly from an electric motor in extension of the motor shaft of the electric motor or it can be provided a rotatable mounting of the shaft, so that the drive, for example as a belt drive can be trained. The shaft can also be rigidly mounted, so that only the laying drum is rotatably mounted on the shaft.

Durch die nur einseitige Montage der Verlegetrommel ist diese einfach und schnell demontierbar und/oder auswechselbar, z.B. um die Aufspulcharakteristik bezüglich des Hubs von Garnspulen zu ändern. Die Verlegtrommel muss daher keine Fenster in der Zylinderoberfläche der Verlegetrommel aufweisen. Eine Reinigung kann ohne größeren Aufwand bei demontierter Verlegetrommel vorgenommen werden. Wenn keine Fenster in der Zylinderoberfläche vorhanden sind kann auf ein Sicherheitsgehäuse verzichtet werden.
Bei der erfindungsgemäßen Verlegetrommel kann also auf eine Tür verzichtet werden da keine rotierenden Öffnungen vorhanden sein müssen.By only one-sided installation of the laying drum this is easy and quick to disassemble and / or interchangeable, for example, to change the Aufspulcharakteristik with respect to the stroke of yarn packages. The laying drum must therefore have no windows in the cylinder surface of the laying drum. A cleaning can be made without much effort in dismantled laying drum. If no windows are present in the cylinder surface can be dispensed with a safety housing.
In the laying drum according to the invention can therefore be dispensed with a door because no rotating openings must be present.

Die erfindungsgemäße Verlegetrommel weist eine Hohlwelle auf, wobei die Hohlwelle, bevorzugt über Kugellager, drehbar gelagert auf die Welle aufgeschoben ist. Die Hohlwelle ist dabei bevorzugt auf eine starre Achse als Welle aufgeschoben und darauf drehbar gelagert. Dadurch kann die Welle starr an der Fadenverlegevorrichtung montiert werden, so dass diese eine starre und ortsfeste, sehr stabile Achse ausbildet. Der Antrieb kann direkt z.B. mittels eines Riemenantriebs an der Hohlwelle eingreifen oder über ein getriebeartiges Kraftübertragungsmodul erfolgen.The laying drum according to the invention has a hollow shaft, wherein the hollow shaft, preferably via ball bearings, is rotatably mounted on the shaft. The hollow shaft is preferably pushed onto a rigid axle as a shaft and rotatably mounted thereon. As a result, the shaft can be rigidly mounted on the thread laying device, so that it forms a rigid and stationary, very stable axis. The drive can be directly connected e.g. engage by means of a belt drive on the hollow shaft or via a gear-type power transmission module.

Erfindungsgemäß umfasst die Verlegetrommel eine montagewellenendenseitig angeordnete erste Trommelhälfte und eine im Bereich des freien Wellenendes angeordnete zweite Trommelhälfte, wobei die Trommelhälften jeweils Teiloberflächen der Zylinderoberfläche der Verlegetrommel ausbilden Dabei wird der fadenführende Schlitz durch einen die Teiloberflächen beabstandenden Spalt ausgebildet. Die beiden Trommelhälften können so mühelos auseinandergebaut werden um z.B. eine Reinigung des Inneren der Verlegetrommel vorzunehmen.According to the invention, the laying drum comprises a first drum half arranged at the end of the assembly shaft and a second drum half arranged in the region of the free shaft end, the drum halves respectively forming partial surfaces of the cylinder surface of the laying drum. The thread-guiding slot is formed by a gap separating the partial surfaces. The two drum halves can be easily disassembled to make eg a cleaning of the inside of the laying drum.

Sehr vorteilhaft ist die montagewellenendenseitig angeordnete erste Trommelhälfte fest mit der Hohlwelle verbunden, bevorzugt verschraubt, und die zweite Trommelhälfte ist auf die Hohlwelle aufgeschoben und auf der Hohlwelle drehfest mit der Hohlwelle verbunden. Derart wird eine fliegende Lagerung der Verlegetrommel realisiert. Derart kann zur Demontage der Verlegetrommel, zunächst die zweite Trommelhälfte abgenommen werden und daraufhin die zweite Trommelhälfte zusammen mit der Hohlwelle von der Welle heruntergeschoben werden. Es ergibt sich dadurch eine sehr starre Anordnung der Verlegetrommel, so dass der zur Führung des Fadens vorgesehen Spalt insbesondere hinsichtlich seiner Spaltbreite sehr starr ist.Very advantageously, the montage shaft end side arranged first half drum is fixedly connected to the hollow shaft, preferably screwed, and the second drum half is pushed onto the hollow shaft and rotatably connected to the hollow shaft with the hollow shaft. Such a flying storage of the laying drum is realized. Thus, for disassembly of the laying drum, first the second drum half can be removed and then the second drum half can be pushed down together with the hollow shaft of the shaft. This results in a very rigid arrangement of the laying drum, so that the gap provided for guiding the thread is very rigid, in particular with regard to its gap width.

Vorteilhaft ist die zweite Trommelhälfte über einen Schnellverschlussmechanismus auf der Hohlwelle befestigt, wodurch das Abnehmen der zweiten Trommelhälfte insbesondere zu Reinigungszwecken noch weiter vereinfacht ist. Der Schnellverschlussmechanismus kann auch zur Einstellung der Spaltbreite des fadenführenden Schlitzes dienen.Advantageously, the second drum half is fastened on the hollow shaft via a quick-release mechanism, whereby the removal of the second drum half is further simplified, in particular for cleaning purposes. The quick release mechanism can also serve to adjust the gap width of the thread guiding slot.

Ein derartiger Schnellverschlussmechanismus kann einen auf die Hohlwelle mit einem Schraubgewinde aufschraubbaren Ring aufweisen, wobei das Schraubgewinde an abkippbar am Ring befestigten Backen ausgebildet ist. Dadurch ergibt sich eine sichere Verschraubung, ohne dass der Ring über einen größeren Gewindeabschnitt fest angeschraubt werden muss.Such a quick release mechanism may comprise a screwed onto the hollow shaft with a screw thread ring, wherein the screw thread is formed on tiltably attached to the ring jaws. This results in a secure screw without the ring must be screwed tight over a larger threaded portion.

Wenn zwischen der ersten Trommelhälfte und der zweiten Trommelhälfte mindestens ein bevorzugt ringförmiges Abstandselement auf die Hohlwelle aufgeschoben ist kann die Spaltbreite des fadenführenden Schlitzes mittels der Dicke und/oder der Anzahl der Abstandselemente festgelegt werden. Dadurch kann die erfindungsgemäße Verlegetrommel an verschieden Fadendicken flexibel angepasst werden.If at least one preferably annular spacer element is pushed onto the hollow shaft between the first drum half and the second drum half, the gap width of the thread-guiding slot can be determined by means of the thickness and / or the number of spacer elements. As a result, the laying drum according to the invention can be flexibly adapted to different thread thicknesses.

Vorteilhaft sind die von den Trommelhälften ausgebildeten Teiloberflächen der Zylinderoberfläche und/oder die Stirnflächen der Verlegetrommel öffnungsfrei ausgeführt. Die Trommeloberfläche ist also geschlossen, d.h. sie weist keine Öffnung zum Reinigen auf. Dadurch wird die Verletzungsgefahr an der Verlegetrommel minimiert.The partial surfaces of the cylinder surface formed by the drum halves and / or the end faces of the laying drum are advantageously designed to be free of openings. The drum surface is thus closed, i. it has no opening for cleaning. This minimizes the risk of injury from the laying drum.

Die Darstellungen der Zeichnungen zeigen den erfindungsgemäßen Gegenstand stark schematisiert und sind nicht maßstäblich zu verstehen. Die einzelnen Bestandteile des erfindungsgemäßen Gegenstandes sind so dargestellt, dass ihr Aufbau gut gezeigt werden kann.The representations of the drawings show the subject matter according to the invention in a highly schematized manner and are not to be understood to scale. The individual components of the article according to the invention are shown so that their structure can be well shown.

Figur 1 zeigt eine erfindungsgemäße Fadenverlegevorrichtung in einem Querschnitt. Die Fadenverlegevorrichtung weist eine, mittels eines Antriebes um eine Drehachse 1 rotierbare, Verlegetrommel 2 auf, die eine Zylinderoberfläche 4 ausbildet. Die Drehachse 1 wird von einer Welle 6 mit zwei Wellenenden ausgebildet. Die Welle 6 ist starr an der Fadenverlegevorrichtung montiert. Eines der Wellenenden ist als Montagewellenende 10 ausgebildet, derart, dass die Welle 6 mit dem Montagewellenende 10 an der Fadenverlegevorrichtung montiert ist und das zweite Wellenende 11 ist als freies Wellenende ausgebildet, derart, dass eine einseitige Lagerung der Verlegetrommel 2 ausgebildet ist. Die Verlegetrommel 2 weist eine Hohlwelle 14 auf, wobei die Hohlwelle 14 drehbar gelagert auf die Welle 6 aufgeschoben ist. Die Hohlwelle 14 ist dabei über Kugellager auf der starren Welle 6 gelagert. Der Antrieb ist als ein Elektromotor 15 ausgebildet, der über einen Riemenantrieb 16 die Rotation der Verlegetrommel antreibt.
Die Verlegetrommel 2 weist eine montagewellenendenseitig angeordnete erste Trommelhälfte 21 und eine im Bereich des freien Wellenendes 11 angeordnete zweite Trommelhälfte 22 auf. Dabei bilden die Trommelhälften 21,22 jeweils Teiloberflächen der Zylinderoberfläche der Verlegetrommel 2 aus. Ein fadenführender Schlitz 25 wird durch einen, die Teiloberflächen beabstandenden, Spalt ausgebildet.
Die montagewellenendenseitig angeordnete, d.h. die in der Figur links angeordnete erste Trommelhälfte 21 ist mittels Schrauben 28 fest mit der Hohlwelle verbunden. Die zweite Trommelhälfte 22 ist auf die Hohlwelle 14 aufgeschoben und auf der Hohlwelle 14 drehfest über einen Flansch 30 mit der Hohlwelle 14 verbunden. Die zweite Trommelhälfte 22 ist mittels eines Schnellverschlussmechanismus 32 auf der Hohlwelle 14 gesichert. FIG. 1 shows a thread laying device according to the invention in a cross section. The thread laying device has a, by means of a drive about a rotation axis 1 rotatable, laying drum 2, which forms a cylinder surface 4. The axis of rotation 1 is formed by a shaft 6 with two shaft ends. The shaft 6 is rigidly mounted on the thread laying device. One of the shaft ends is designed as a mounting shaft end 10, such that the shaft 6 is mounted with the mounting shaft end 10 on the thread laying device and the second shaft end 11 is formed as a free shaft end, such that a one-sided mounting of the laying drum 2 is formed. The laying drum 2 has a hollow shaft 14, wherein the hollow shaft 14 is rotatably mounted on the shaft 6 is pushed. The hollow shaft 14 is mounted on ball bearings on the rigid shaft 6. The drive is designed as an electric motor 15, which drives the rotation of the laying drum via a belt drive 16.
The laying drum 2 has a first drum half 21 arranged on the assembly shaft end side and a second drum half 22 arranged in the region of the free shaft end 11. The drum halves 21, 22 each form part surfaces of the cylinder surface of the laying drum 2. A thread guiding slot 25 is formed by a gap spacing the sub-surfaces.
The montagewellenendenseitig arranged, ie the left in the figure arranged first drum half 21 is connected by means of screws 28 fixed to the hollow shaft. The second drum half 22 is on the hollow shaft fourteenth deferred and rotatably connected to the hollow shaft 14 via a flange 30 with the hollow shaft 14. The second drum half 22 is secured on the hollow shaft 14 by means of a quick-lock mechanism 32.

Die rechte Trommelhälfte ist daher schnell z.B. zu Reinigungszwecken entfernbar. Es können daher geschlossene Trommelbleche vorhanden sein, d.h. die Zylinderoberfläche der Verlegetrommel 2 muss keine Fenster mehr aufweisen. Eine Abdeckung der rotierenden Verlegetrommel 2, z.B. mittels einer Türe, kann daher unterbleiben.The right drum half is therefore fast, e.g. removable for cleaning purposes. There may therefore be closed drum sheets, i. the cylinder surface of the laying drum 2 no longer needs to have any windows. A cover of the rotating laying drum 2, e.g. by means of a door, can therefore be omitted.

Figur 2 zeigt zwei Verlegetrommeln einer erfindungsgemäßen Fadenverlegevorrichtung mit unterschiedlichen Aufspulcharakteristika. Die in der Figur oben dargestellte Verlegetrommel weist z.B. einen Hub von 6 Zoll und die in der Figur unten dargestellte Verlegetrommel weist z.B. einen Hub von 1,5 Zoll auf. Damit die Grundbauteile der Verlegetrommeln identisch ausgebildet sein können, ist die im Bereich des freien Wellenendes angeordnete zweite Trommelhälfte 22 in der Länge ihrer Längsachse derart ausgebildet, dass sie jeweils unter Ausbilden eines gewünschten fadenführenden Schlitzes 25 an identischer Position auf der Hohlwelle 14 montierbar ist. Dies ermöglicht ein schnelles Umstellen der Hübe der Verlegetrommel durch Wechselsätze der Trommelbleche bzw. der Trommelhälften 21,22. FIG. 2 shows two laying drums of a yarn laying device according to the invention with different Aufspulcharakteristika. For example, the laying drum shown in the figure above has a stroke of 6 inches, and the laying drum shown in the figure below has, for example, a stroke of 1.5 inches. So that the basic components of the laying drums can be formed identically, the second drum half 22 arranged in the region of the free shaft end is designed in the length of its longitudinal axis such that it can be mounted on the hollow shaft 14 at identical positions to form a desired thread-guiding slot 25. This allows a rapid changeover of the strokes of the laying drum by changing sets of the drum plates and the drum halves 21,22.

Figur 3 zeigt einen Querschnitt einer Ausführungsform einer erfindungsgemäßen Fadenverlegevorrichtung mit geschlossener Verlegetrommel.
Das Montagewellenende 10 ist in der Figur auf der linken Seite der Verlegetrommel 2 angeordnet. Die Welle 6 ist also als starre Welle mittels einer Schraubenmutter, z.B. einer Sechskantmutter 50, an einem Halteelement 52, z.B. einem Gehäuse, einer Fadenverlegevorrichtung montiert, d.h. festgeschraubt. Die Verlegetrommel 2 hat eine, abgesehen vom fadenführenden Schlitz 25, geschlossene Zylinderoberfläche, d.h. die Trommelbleche sind geschlossen. FIG. 3 shows a cross section of an embodiment of a yarn laying device according to the invention with a closed laying drum.
The mounting shaft end 10 is arranged in the figure on the left side of the laying drum 2. The shaft 6 is thus mounted as a rigid shaft by means of a nut, for example a hex nut 50, on a holding element 52, for example a housing, a thread laying device, that is screwed tight. The laying drum 2 has one, apart from the thread-guiding Slot 25, closed cylinder surface, ie the drum plates are closed.

Die in der Figur linke Trommelhälfte weist einen Flansch 60, an dem das Trommelblech 61 befestigt ist, auf. Der Flansch 60 ist über Verbindungselemente an der als Hohlwelle dienenden Buchse 63 und an einem Antriebsrad 65 befestigt. Die Buchse 63 und das Antriebsrad 65 sind über Kugellager 67,68 auf der Welle 6, im Falle des in der Figur rechten Kugellagers 68 über eine in die Welle 6 eingesteckte Hülse 71, gelagert. Eine Büchse 69 dient als Abstandshalter. Die in der Figur rechte Trommelhälfte ist über eine Verdrehsicherung 70 an der Buchse 63 montiert und mittels eines Verschlusses arretiert. Der Verschluss ist als ein Schnellverschluss mit einem Sprengring 75 ausgebildet und auf einen an Buchse 63 befestigten Gewindezapfen 76 aufgeschraubt.The left half of the drum in the figure has a flange 60, on which the drum plate 61 is attached, on. The flange 60 is fastened via connecting elements to the sleeve 63 serving as a hollow shaft and to a drive wheel 65. The bush 63 and the drive wheel 65 are mounted on the shaft 6 via ball bearings 67, 68, in the case of the right ball bearing 68 in the figure via a sleeve 71 inserted in the shaft 6. A bush 69 serves as a spacer. The right half of the drum in the figure is mounted on the sleeve 63 via an anti-rotation device 70 and locked by means of a closure. The closure is formed as a quick release with a snap ring 75 and screwed onto a threaded pin 76 attached to bushing 63.

Um ein Starten der Trommel bei entfernter rechter Trommelhälfte zu verhindern, kann die Position derselben überwacht werden. Dies kann geschehen durch einen Sensor, z.B. einen Hallsensor 80, der auf der feststehenden Hohlwelle 6 montiert ist und den axialen Abstand des Verschlusses überwacht. Dazu sind am Verschluss Magnethalter vorgesehen. Das Kabel des Sensors wird durch die Hohlwelle 6 weggeführt.To prevent the drum from starting when the right half of the drum is removed, its position can be monitored. This can be done by a sensor, e.g. a Hall sensor 80 which is mounted on the fixed hollow shaft 6 and monitors the axial distance of the shutter. For this purpose magnet holders are provided on the closure. The cable of the sensor is led away through the hollow shaft 6.

Die beiden Trommelhälften links und rechts bilden einen Schlitz 25, der den Faden hin und her bewegt während derselbe von der Garnspule aufgewickelt wird.
Die Genauigkeit der Fadenführung (Changierbewegung) wird durch die Schlitzbreite beeinflusst. Je kleiner der Schlitz, desto genauer die Führung.The two drum halves left and right form a slot 25 which moves the yarn back and forth while being wound up by the yarn package.
The accuracy of the thread guide (traversing movement) is influenced by the slot width. The smaller the slot, the more accurate the guide.

Die Schlitzbreite kann eingestellt werden durch Distanzscheiben, welche auf die Buchse 63 aufgesteckt die Distanz zwischen Buchse 63 und Flansch 90, in der Figur rechts, bilden.The slot width can be adjusted by spacers, which plugged onto the socket 63, the distance between the socket 63 and flange 90, in the figure to the right.

Konventionell hat man den Schlitz 25 auf das gröbste Garn eingestellt um die Einrichtarbeit zu reduzieren.
Mittels dieser bevorzugten Ausführungsform der erfindungsgemäßen Verlegetrommel kann in kürzester Zeit der Schlitz 25 auf das jeweils zu produzierende, d.h. aufzuspulende, Garn optimal eingestellt werden.
Durch das komplette Entfernen der rechten Hälfte wird das Reinigen stark vereinfacht. In Figur 4 ist die erfindungsgemäße Fadenverlegevorrichtung aus Figur 3 mit geöffneter Verlegetrommel dargestellt. Dabei ist die zweite Trommelhälfte von der Hohlwelle 6 und der Buchse 63 heruntergeschoben, nach rechts abgesetzt dargestellt.Conventionally, the slot 25 has been adjusted to the coarsest yarn to reduce set-up work.
By means of this preferred embodiment of the laying drum according to the invention, the slit 25 can be set optimally in the shortest possible time to the respective yarn to be produced, ie to be wound up.
By completely removing the right half, cleaning is greatly simplified. In FIG. 4 is the thread laying device according to the invention FIG. 3 shown with open laying drum. The second drum half of the hollow shaft 6 and the sleeve 63 is pushed down, shown offset to the right.

Die Figur 5 zeigt den Aufbau der Verdrehsicherung 70 zur drehfesten Verbindung der zweiten Trommelhälfte mit der als Buchse bezeichneten Hohlwelle 63 in einem Ausschnitt einer dreidimensionalen Darstellung. Die Verdrehsicherung 70 ist durch Nocken 100 an der Hohlwelle 63, die in Nuten 102 an der zweiten Trommelhälfte eingreifen, realisiert.The FIG. 5 shows the structure of the anti-rotation device 70 for the rotationally fixed connection of the second drum half with the sleeve designated as the hollow shaft 63 in a section of a three-dimensional representation. The anti-rotation device 70 is realized by cams 100 on the hollow shaft 63, which engage in grooves 102 on the second drum half.

Figur 6 zeigt eine bevorzugte Ausführungsform eines Schnellverschlussmechanismus zur Sicherung der zweiten Trommelhälfte auf der Hohlwelle.
Der Verschluss kann auch durch einen Schnellverschluss realisiert werden. Bei diesem werden anstelle des einfachen Gewindes in der Verschlussseite Gewindesegmente 110 eingesetzt, welche durch Zusammendrücken über das Gewinde auf der linken Seite geschoben werden können, bis auf Anschlag. Dazu sind die Gewindesegmente 110 an Backen 112 zum Zusammendrücken vorgesehen. Ein Zusammendrücken der Backen 112 erlaubt ein rasches Einfahren des Verschlusses, da die Gewindesegmente dadurch radial nach außen weggedrückt werden. Mit einem minimalen Aufwand kann der Verschluss nun durch Drehen vorgespannt werden. FIG. 6 shows a preferred embodiment of a quick release mechanism for securing the second drum half on the hollow shaft.
The closure can also be realized by a quick release. In this thread segments 110 are used instead of the simple thread in the closure side, which can be pushed by squeezing over the thread on the left side, to the stop. For this purpose, the thread segments 110 are provided on jaws 112 for compression. Compression of the jaws 112 allows for rapid retraction of the closure as the thread segments are thereby forced radially outward. With a minimum of effort, the closure can now be biased by turning.

Ein derartiger Schnellverschluss ist sehr sicher gegen dessen Lösen. Das Gewinde kann selbsthemmend ausgeführt sein. Ein Überlastmoment wird durch Federn 114 definiert. Wenn das Anzugsdrehmoment, d.h. die axiale Vorspannkraft durch den Schnellverschluss, nicht ausreicht, wird lediglich das Spulbild beeinträchtigt. Die Verletzungsgefahr bleibt gering.Such a quick release is very safe against its release. The thread can be self-locking. An overload torque is defined by springs 114. If the tightening torque, i. the axial preload force by the quick release, is not sufficient, only the Spulbild is impaired. The risk of injury remains low.

Figur 7 zeigt die Handhabung des in Figur 6 gezeigten Schnellverschlusses. Zunächst wird der Schnellverschluss, wie in Figur 7a dargestellt, zusammengedrückt und eingefahren. Dann wird, wie in Figur 7b dargestellt, die rechte Trommelhälfte bis an einen Anschlag, z.B. an einen Positionierstift 120 für eine Verlegekante, eingeschoben. Der Schnellverschluss wird nun losgelassen.
Abschließend wird, wie in Figur 7c dargestellt, am Verschluss gedreht, bis die Kupplung, d.h. die Gewindebacken, überschnappen. FIG. 7 shows the handling of in FIG. 6 shown quick release. First, the quick release, as in Figure 7a shown, compressed and retracted. Then, as in FIG. 7b represented, the right half drum to a stop, for example, to a positioning pin 120 for a laying edge, inserted. The quick release is now released.
In conclusion, as in FIG. 7c shown turned on the closure until the coupling, ie the threaded jaws, snap over.

Figur 8 zeigt eine weitere Verschlussvariante zur Fixierung der zweiten Trommelhälfte mit einem Standard-Gewinde.
Die rechte Trommelhälfte wird durch ein Gewinde 130 auf die linke Hälfte verschraubt. Dies kann mit einem insbesondere frei beweglichen Drehgriff 132 geschehen, der sich auf der rechten Hälfte drehen lässt. Die linke Trommelhälfte weist dabei einen fest auf den Rotationskörper montierten Gewindezapfen 134 auf. FIG. 8 shows a further closure variant for fixing the second drum half with a standard thread.
The right half of the drum is screwed by a thread 130 on the left half. This can be done with a particular freely movable rotary handle 132, which can be rotated on the right half. The left half of the drum in this case has a fixedly mounted on the rotary body threaded pin 134.

Zur Halterung der Teiloberflächen der Zylinderoberfläche der Verlegetrommel an den Stirnseiten der Verlegetrommelhälften können Stabilisierungsrippen im Inneren der Verlegetrommel vorgesehen sein.For holding the partial surfaces of the cylinder surface of the laying drum on the end faces of the laying drum halves stabilizing ribs may be provided in the interior of the laying drum.
