Abstract

The invention relates to a method for placing fibrous material in a can (1) having a first step, in which a fibrous-material-placement head is positioned above the can (1) in a predetermined starting position (2). A cycle follows. The cycle comprises a first cycle step in which a predetermined fibrous-material length is placed into the can (1). I.e. the position of the placement head does not change. Subsequently, in a second cycle step, the placement head is shifted away from the current position according to predetermined information. The predetermined fibrous-material length is different at least between two cycles.

Description

Titel: Verfahren zum Ablegen von Faserband in einer Spinnkanne Title: Method of depositing sliver in a sliver can
Beschreibung description
Die Erfindung betrifft das Ablegen von Fasermaterial in einer Spinnkanne. The invention relates to the depositing of fiber material in a spinning can.
Verfahren zum Ablegen von Fasermaterial, insbesondere von Faserband, beinhaltet das Rotieren eines feststehenden Ablagetellers über einer Kanne. Im Fall einer Rundkanne rotiert diese, und im Fall einer Rechteck kanne wird diese changiert. Dies führt dazu, dass nach jeder Kannenum drehung bzw. Changierbewegung die nächste Lage an Faserband über denselben Faserbandringen der vorherigen Faserbandlage abgelegt wird. Dadurch liegen die Kreuzungspunkte der einzelnen Faserband-Ablageebe- nen vertikal übereinander. Dies führt dazu, dass das Faserband sehr schnell an Höhe gewinnt. Dies erfordert, dass das Faserband, um genü gend Fasermaterial ablegen zu können, stark gepresst werden muss, was sich nachteilig auf die Fasermaterialqualität auswirkt. A method for depositing fiber material, in particular fiber sliver, includes rotating a stationary depositing plate over a can. In the case of a round jug, it rotates, and in the case of a rectangular jug, it is oscillated. This leads to the fact that after each Kannenum rotation or traversing movement, the next layer of sliver is deposited over the same sliver rings of the previous sliver layer. As a result, the points of intersection of the individual sliver storage levels lie vertically one above the other. This causes the sliver to gain height very quickly. This requires that the fiber tape, in order to be able to deposit enough fiber material, must be pressed strongly, which has a negative effect on the fiber material quality.
Diesem Problem zu begegnen, ist bekannt, die Position des Ablagekopfes Kanne unregelmäßig zu verändern. Dies hat den Nachteil, dass es völlig unbestimmt ist, wo die Kreuzungspunkte ausgebildet sind und wieviel La gen Fasermaterial an diesen Punkten übereinander liegen. Insbesondere kann der Fall auftreten, dass an einigen Kreuzungspunkten wesentlich we niger Lagen übereinander liegen als an anderen Kreuzungspunkten, so- dass sich die maximal einfüllbare Fasermaterialmenge reduzieren kann. Es kann im Ergebnis nicht vorherbestimmt werden, wie viel Fasermaterial letzt endlich in der Kanne abgelegt werden kann. Auch führt diese Art des Ver- lagerns des Ablagekopfes zu ruckartigen Bewegungen und damit zu Belas tungen der Kannenablagevorrichtung. Aufgabe der Erfindung ist es, den vorgenannten Nachteilen zu begegnen. To counter this problem, it is known to irregularly change the position of the jug storage head. This has the disadvantage that it is completely indeterminate where the crossing points are formed and how many layers of fiber material lie on top of one another at these points. In particular, the case can arise that at some intersection points there are significantly fewer layers on top of one another than at other intersection points, so that the maximum amount of fiber material that can be filled can be reduced. As a result, it cannot be determined in advance how much fiber material can finally be deposited in the can. This type of displacement of the depositing head also leads to jerky movements and thus to loads on the can depositing device. The object of the invention is to counter the aforementioned disadvantages.
Diese Aufgabe wird durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angege ben. This problem is solved by the subject matter of the independent claim. Advantageous developments are indicated in the subclaims.
Ein erfindungsgemäßes Verfahren zum Ablegen von Fasermaterial in einer Kanne weist einen ersten Schritt auf, in dem ein Fasermaterial-Ablagekopf über der Kanne in eine vorbestimmte Startposition positioniert wird. Darauf hin schließt sich ein Zyklus an. Der Zyklus umfasst einen ersten Zyklus schritt, in dem eine vorbestimmte Fasermateriallänge in die Kanne abgelegt wird. D. h. die Position des Ablagekopfes ändert sich nicht. Darauffolgend wird der Ablagekopf in einem zweiten Zyklusschritt von der aktuellen Posi- tion weg gemäß vorbestimmten Angaben verlagert. Dies bedeutet, dass ge nau bestimmt werden kann, wieviel Fasermaterial bei Beibehalten einer Po sition durch den Ablagekopf in die Kanne abgelegt wird. Das vorbestimmte Verlagern des Ablagekopfes ermöglicht es, bei einer vorgegebenen Anzahl an Lagen die Anzahl von an den Kreuzungspunkten übereinanderliegenden Lagen zu reduzieren und damit die Füllmenge maximieren und/oder insbe sondere die Qualität des abgelegten Fasermaterials positiv beeinflussen zu können. Die vorbestimmte Fasermateriallänge ist zwischen zumindest zwei Zyklen zueinander unterschiedlich. Dies ermöglicht insbesondere bei Rund kannen, auch bei nur zwei vorgegebenen Positionen des Ablagekopfes die Position der Kreuzungspunkte vorhersagbar variieren zu können. A method according to the invention for depositing fiber material in a can has a first step in which a fiber material depositing head is positioned above the can in a predetermined starting position. This is followed by a cycle. The cycle comprises a first cycle step in which a predetermined length of fiber material is deposited in the can. I.e. the position of the storage head does not change. Then, in a second cycle step, the storage head is shifted away from the current position according to predetermined information. This means that it can be precisely determined how much fiber material is deposited in the can by the depositing head while maintaining a position. The predetermined shifting of the depositing head makes it possible to reduce the number of superimposed layers at the intersection points with a given number of layers and thus maximize the filling quantity and / or in particular be able to positively influence the quality of the deposited fiber material. The predetermined fiber material length differs from one another between at least two cycles. In particular in the case of round cans, this makes it possible to predictably vary the position of the crossing points even with only two predetermined positions of the storage head.
Vorzugsweise wiederholt sich der Zyklus, bis die Kanne gefüllt ist. Vorzugsweise beträgt eine vorbestimmte Fasermateriallänge der Abgabe menge während einer Kannenumdrehung. Dies ist eine steuerungstech nisch sehr einfach zu realisierende Form, die Ablage von Fasermaterial zu optimieren. The cycle is preferably repeated until the jug is filled. Preferably, the dispensing amount is a predetermined length of fiber material during one can revolution. This is a form that is very easy to implement in terms of control technology to optimize the storage of fiber material.
Alternativ oder zusätzlich entspricht eine vorbestimmte Fasermateriallänge der Abgabemenge während des Ablegens eines Fasermaterialrings. Dies ermöglicht das mehrfache Verändern der Ablagekopf-Position während der Ablage einer Fasermaterialebene, die während einer Kannenumdrehung abgelegt wird. Dabei kann der Ablagekopf von einer Endposition zur ande ren schrittweise oder gar kontinuierlich Faserbandring verlagert werden. Alternatively or in addition, a predetermined fiber material length corresponds to the amount dispensed during the laying down of a fiber material ring. This enables the placement head position to be changed several times during the placement of a fiber material level that is placed during one can rotation. The storage head can be shifted gradually or even continuously from one end position to the other.
Vorzugsweise erfolgt das Verlagern des Ablagekopfes in zumindest einem Zyklus zwischen mehreren vorbestimmten Endposition des Ablagekopfes. Damit erhöhen sich die Freiheitsgrade, das Fasermaterial optimal ablegen zu können. The disposition of the storage head is preferably carried out in at least one cycle between several predetermined end positions of the storage head. This increases the degree of freedom to be able to optimally lay down the fiber material.
Vorzugsweise erfolgt die Faserbandablage so, dass verhindert wird, dass bei einer Kannenumdrehung eine ganzzahlige Anzahl von Fasermaterial ringen abgelegt wird. Dies bedeutet, dass nach einer Kannenumdrehung nicht etwa ein Faserbandring anfängt sondern etwas später. Auch dies be wirkt eine Reduzierung der Lagen, die an den Kreuzungspunkten überei- nanderliegen. The sliver deposit is preferably carried out in such a way that an integral number of fiber material rings is prevented from being deposited during one can revolution. This means that after one can rotation, a sliver ring does not start but a little later. This also has the effect of reducing the positions that lie one above the other at the crossing points.
Das Verlagern des Ablagekopfes erfolgt vorzugsweise, indem der Ablage kopf am Beginn des jeweiligen Verlagerns gezielt beschleunigt wird und/o der am Ende des jeweiligen Verlagerns gezielt abgebremst wird. Dies führt zu relativ geringen Belastungen an der Kannenablagevorrichtung, die den Ablagekopf aufweist und verfährt. Vorzugsweise handelt es sich bei dem abgelegten Fasermaterial um ein Faserband ist. The displacing of the storage head is preferably carried out in that the storage head is specifically accelerated at the beginning of the respective displacement and / o which is specifically braked at the end of the respective displacement. This leads to relatively low loads on the can depositing device, which has the depositing head and moves. The deposited fiber material is preferably a fiber tape.

Figur 5 eine Rundkanne in zwei Füllzuständen, die gemäß einem Faser- material-Ablageverfahren gemäß der vierten Ausführungsform der Erfindung gefüllt wurde, FIG. 5 shows a round can in two filling states, which was filled according to a fiber material storage method according to the fourth embodiment of the invention,
Figur 6 Diagramme, die Ablageverfahren gemäß anderer Ausführungsfor men der Erfindung darstellen, und Figur 7 eine Rundkanne in zwei Füllzuständen gemäß einem Fasermate- rial-Ablageverfahren gemäß der in Figur 6d gezeigten Ausfüh rungsform der Erfindung und in einer Seitenansicht. FIG. 6 is a diagram showing storage methods according to other embodiments of the invention, and FIG FIG. 7 shows a round can in two filling states according to a fiber material deposition method according to the embodiment of the invention shown in FIG. 6d and in a side view.
Figur 1 zeigt eine Rundkanne 1 in zwei Füllzuständen gemäß einem Faser- material-Ablageverfahren gemäß einer ersten Ausführungsform der Erfin dung. In Figur 1 a ist die Kanne 1 in einem Zustand gezeigt, in dem sie eine einzige Umdrehung während des Füllens mit Fasermaterial durchlaufen hat. Bei den dabei abgelegten Faserbandringen ist in den Figuren nur je weils der oberste mit Bezugszeichen 7 versehen. In der Mitte der Kanne 1 bildet sich ein Spundloch 5 heraus. Wie zu erkennen, wechselt die Position des Ablagekopfes von einer Position 3 zu einer Position 2. Die Position 2, 3 bezeichnet dabei immer den Mittelpunkt des jeweilig abgelegten Faserban drings 7. Figure 1 shows a round can 1 in two filling states according to a fiber material storage method according to a first embodiment of the invention. In FIG. 1 a, the can 1 is shown in a state in which it has passed through a single rotation during the filling with fiber material. In the case of the sliver rings deposited in this case, only the uppermost one is provided with reference numeral 7 in the figures. A bunghole 5 is formed in the middle of the can 1. As can be seen, the position of the depositing head changes from a position 3 to a position 2. The position 2, 3 always denotes the center point of the respective deposited fiber strip 7.
Ist die Kanne 1 gefüllt, zeigt sich der in Figur 1 b gezeigte Zustand. Wie zu erkennen, ist das Spundloch 5 sehr klein geworden. Auch reduziert sich dadurch die Anzahl der Lagen an Fasermaterial an den Kreuzungspunkten in vertikaler Richtung, d. h. gemäß Figur 1 in die Blattebene hinein oder aus der Blattebene heraus. If the jug 1 is filled, the state shown in FIG. 1b is shown. As can be seen, the bung hole 5 has become very small. This also reduces the number of layers of fiber material at the intersection points in the vertical direction, i. H. according to FIG. 1 into or out of the plane of the sheet.
Figur 2 zeigt zwei Abbildungen zur Faserbandablage in einer Rundkanne 1 , gemäß einer zweiten Ausführungsform der Erfindung. Gemäß dem in Figur 2a gezeigten Verfahren gibt es drei Positionen 3 - 5 für den Ablagekopf. Als eine Variante ergibt sich das in Figur 2b dargestellte Bild mit verschiedenen Ablageebenen 61 - 65. Wie auch hier zu erkennen, ist das Spundloch 5 ebenfalls sehr klein. In der untersten Ebene (Position 4) werden die Ringe 7 vorzugsweise entlang des Innenraums der sonst weiter nicht dargestellten Kanne 1 abgelegt. Danach wechselt der Ablagekopf in Position 3, die einer mittleren Position des Ablagekopfes entspricht. Danach wird in zwei Ebenen übereinander der Ablagekopf in Position 2 bewegt bzw. dort belassen. Da nach wird wieder zu Position 4 gefahren, und danach in Position 2. Der Wechsel zwischen den Positionen 2 - 4 erfolgt demzufolge immer nach ei ner einzigen Kannenumdrehung bzw. der Faserbandlänge, die bei der je weiligen Position 2 - 4 während einer Kannenumdrehung abgelegt wird. Die Daten hinsichtlich der jeweiligen Faserbandlänge können in Verbindung mit der jeweiligen Ablagekopfposition in einer Datenbank hinterlegt und mittels der Steuerung des Ablagekopfes einfach ausgelesen werden. Es ergibt sich mithin ein sehr einfach zu realisierendes Verfahren, den Ablagekopf zu be wegen bzw. in der jeweiligen Position zu belassen. Figure 2 shows two images of sliver storage in a round can 1, according to a second embodiment of the invention. According to the method shown in Figure 2a, there are three positions 3-5 for the storage head. The image shown in FIG. 2b with different storage levels 6 1 - 6 5 results as a variant. As can also be seen here, the bunghole 5 is also very small. In the lowest level (position 4), the rings 7 are preferably placed along the interior of the jug 1, which is otherwise not shown. The storage head then changes to position 3, which corresponds to a middle position of the storage head. After that it is in two levels one above the other, the storage head moved to position 2 or left there. Then it goes back to position 4, and then to position 2. The change between positions 2 - 4 therefore always takes place after a single can revolution or the sliver length, which is deposited in the respective position 2 - 4 during one can revolution . The data regarding the respective sliver length can be stored in a database in connection with the respective storage head position and can be easily read out by means of the control of the storage head. The result is a very easy to implement method of moving the storage head or leaving it in the respective position.
Figur 3 zeigt eine Rundkanne 1 , die gemäß einem Fasermaterial-Ablage- verfahren gemäß einer dritten Ausführungsform der Erfindung gefüllt wurde. Auch hier gibt es drei Ablagepositionen 2 - 4. Allerdings ist das Faserband so abgelegt, dass die Positionen nacheinander kontinuierlich angefahren werden (Reihenfolge: 2, 3, 4, 2, 3, 4, ... ). FIG. 3 shows a round can 1 which has been filled using a fiber material depositing method according to a third embodiment of the invention. There are also three deposit positions 2 - 4. However, the sliver is deposited in such a way that the positions are continuously approached one after the other (sequence: 2, 3, 4, 2, 3, 4, ...).
Figur 4 zeigt eine Rundkanne 1 , die gemäß einem Fasermaterial-Ablage- verfahren gemäß der dritten Ausführungsform der Erfindung gefüllt wurde. Allerdings ist der Durchmesser der hier dargestellten Rundkanne 1 größer als in Figur 2. Daraus ergibt sich das in Figur 4 etwas andere Ablagebild in Vergleich zu Figur 2. FIG. 4 shows a round can 1 which has been filled using a fiber material deposition method according to the third embodiment of the invention. However, the diameter of the round can 1 shown here is larger than in FIG. 2. This results in the deposition image in FIG. 4 which is somewhat different from that in FIG.
Figur 5 zeigt eine Rundkanne 1 in zwei Füllzuständen gemäß einem Faser- material-Ablageverfahren gemäß einer vierten Ausführungsform der Erfin dung. Bei dieser Ausführungsform gibt es wiederum lediglich zwei Positio nen 2, 3 für den Ablagekopf. Allerdings wird der Ablagekopf während einer Kannenumdrehung kontinuierlich von der Position 2 in Position 3 und wie der zurück bewegt. D. h. der Abstand der Faserbandringe 7 zur Innenwand der Kanne 1 verändert sich vorzugsweise kontinuierlich. Zudem ergibt sich gemäß Figur 5a nach einer Kannenumdrehung, dass der Faserbandring 7 etwas nach rechts versetzt in Bezug auf eine vertikale Mittelachse an der Innenwand der Kanne 1 anliegt. Zu Beginn des Faserband-Ablegens befand sich der Mittelpunkt des entsprechenden Faserbandrings 7 allerdings direkt auf der Mittelachse. D. h. die Position 2, die der Ablagekopf wiederholt an fährt,„wandert“ entlang einer Kreislinie um den Mittelpunkt der Kanne 1 herum. FIG. 5 shows a round can 1 in two filling states according to a fiber material deposition method according to a fourth embodiment of the invention. In this embodiment there are again only two positions 2, 3 for the storage head. However, the delivery head is continuously moved from position 2 to position 3 and back again during one can rotation. I.e. the distance between the sliver rings 7 and the inner wall of the can 1 preferably changes continuously. It also results According to FIG. 5a, after one can rotation, the sliver ring 7 rests against the inner wall of the can 1, offset somewhat to the right with respect to a vertical central axis. At the beginning of the filing of the sliver, the center of the corresponding sliver ring 7 was, however, directly on the central axis. I.e. Position 2, which the delivery head repeatedly moves to, “wanders” along a circular line around the center of the jug 1.
Ist die Kanne 1 gefüllt, ergibt sich ein in Figur 5b dargestelltes Ablagebild. Auch hier ist zu erkennen, dass das Spundloch 5 wiederum sehr klein ge raten ist. If the jug 1 is filled, a deposit image shown in FIG. 5b results. Here, too, it can be seen that the bunghole 5 is again very small.
Figur 6 zeigt drei Diagramme, die verschiedene Ablageverfahren darstellen. FIG. 6 shows three diagrams which represent different storage methods.
Gemäß Figur 6a wird nur während der ersten drei Kannenumdrehungen die Position des Ablagekopfes hier zwischen zwei Positionen 2, 3 gewechselt. Danach verbleibt der Ablagekopf in Position 3, wie es bei klassischen Abla geverfahren bekannt ist. Die gestrichelten Linien dienen dem Zweck, die entsprechenden Knickpunkte des Graphen in Bezug auf die jeweilige Kan nenumdrehung zu verdeutlichen. According to FIG. 6a, the position of the depositing head is changed here between two positions 2, 3 only during the first three can revolutions. The storage head then remains in position 3, as is known from classic storage methods. The dashed lines are used to clarify the corresponding breakpoints of the graph in relation to the respective cannon revolution.
Gemäß Figur 6b wiederum erfolgt der Wechsel zwischen den Positionen 2, 3 nach jeder Kannenumdrehung, und zwar wiederum, bis die Kanne 1 bei Kannenumdrehung n gefüllt ist. According to FIG. 6b, in turn, the change between positions 2, 3 takes place after each can revolution, namely again until the can 1 is filled at can revolution n.
Gemäß Figur 6c erfolgt der Wechsel zwischen den Positionen 2, 3 nach jeweils etwas mehr als einer Kannenumdrehung (beispielsweise nach einer Kannenrotation um 370°), und wiederum, bis die Kanne 1 bei Kannenum drehung n gefüllt ist. Gemäß Figur 6d erfolgt der Wechsel zwischen den Positionen 2, 3 abwech selnd nach jeweils etwas weniger als einer Kannenumdrehung (beispiels weise nach einer Kannenrotation um 350°) und nach genau einer Kan nenumdrehung, und zwar wiederum, bis die Kanne 1 bei Kannenumdre hung n gefüllt ist. According to FIG. 6c, the change between positions 2, 3 takes place after a little more than one can rotation (for example after a can rotation by 370 °), and again until the can 1 is filled at can rotation n. According to Figure 6d, the change between positions 2, 3 takes place alternately after a little less than one can rotation (for example after a can rotation by 350 °) and after exactly one can rotation, again until the can 1 at can rotation n is filled.
Figur 7 zeigt eine Rundkanne 1 in drei Füllzuständen gemäß dem Faser- material-Ablageverfahren von Figur 6d. In Figur 7a ist die Kanne 1 in einem Zustand gezeigt, in dem sie eine einzige Umdrehung während des Füllens mit Fasermaterial durchlaufen hat, und Figur 7b zeigt die Kanne 1 nach zwei Kannenumdrehungen. FIG. 7 shows a round can 1 in three filling states according to the fiber material deposition method of FIG. 6d. In FIG. 7a, the can 1 is shown in a state in which it has passed through a single revolution during filling with fiber material, and FIG. 7b shows the can 1 after two can revolutions.
Figur 7c zeigt die Wirkung des Positionswechsels des Ablagekopfes bei ge füllter Kanne 1 . Dieser Wechsel führt dazu, dass die sonst vertikal überei nanderliegenden, korrespondierenden Stellen zweier unmittelbar überei nanderliegender Faserbandringe 7„wandert“, und zwar nach schräg rechts oben. Es ist klar, dass demzufolge an den Kreuzungspunkten bei voller Kanne 1 weniger Lagen vertikal übereinander liegen. FIG. 7c shows the effect of changing the position of the depositing head when the jug 1 is filled. This change leads to the fact that the corresponding points of two sliver rings 7 lying directly one above the other, which are otherwise vertically one above the other, “migrate”, specifically to the top right at an angle. It is clear that consequently fewer layers are vertically one above the other at the crossing points when the can 1 is full.
Die Erfindung ist nicht auf die vorstehend angegebenen Ausführungsfor men beschränkt. Sie können in jeder Form gegeneinander ausgetauscht oder miteinander kombiniert werden. The invention is not limited to the above-mentioned Ausführungsfor men. They can be exchanged for one another in any form or combined with one another.
Die Anzahl der Positionen, die der Ablagekopf anfährt, kann variieren. Ins besondere kann sie größer als 3 betragen. The number of positions that the delivery head moves to can vary. In particular, it can be greater than 3.
Das Verfahren ist nicht auf ein bestimmtes Fasermaterial beschränkt. Das Fasermaterial ist vorzugsweise Faserband, kann auch beispielsweise Vor garn sein. Das Verfahren gemäß Figur 5 kann mit dem Verfahren gemäß Figur 1 bei spielsweise so kombiniert sein, dass sich die Ringposition 7 gemäß Figur 5a nach einer Kannenumdrehung verändert, aber auch der Ablagekopf seine Position ändert. The method is not restricted to a specific fiber material. The fiber material is preferably sliver, can also be, for example, before yarn. The method according to FIG. 5 can be combined with the method according to FIG. 1, for example, in such a way that the ring position 7 according to FIG. 5a changes after one can rotation, but the placement head also changes its position.
Die Rotationswinkel der Kanne 1 hinsichtlich der Positionswechsel des Ab lagekopfes können bei allen Verfahren immer oder nur teilweise gleich, klei ner oder auch größer als 360° sein. Im Ergebnis schafft die Erfindung ein sehr universell einsetzbares Verfah ren, bei dem vorherbestimmt werden kann, wo sich Kreuzungspunkte be finden, und wie viel lagen voraussichtlich an diesem Kreuzungspunkte über einander liegen. The angle of rotation of the can 1 with regard to the change in position of the storage head can always or only partially be the same, smaller or greater than 360 ° in all methods. As a result, the invention creates a very universally applicable method, in which it can be determined in advance where intersection points are to be found, and how many are likely to lie on top of each other at these intersection points.
