Beschreibungdescription
Die Erfindung betrifft eine Bandablagevorrichtung mit einer Trag¬ konstruktion- mit Mitteln zum Zuführen eines Faserbandes, mit Mitteln zum epizykloidalen Ablegen des Faserbandes in einen an der Oberseite offenen Behälter sowie mit einer auf der Tragkon¬ struktion drehbar angeordneten horizontalen Basis zur Halterung des Behälters.The invention relates to a tape depositing device with a support structure with means for feeding a fiber ribbon, with means for epicycloidal depositing of the fiber ribbon into a container open at the top, and with a horizontal base rotatably arranged on the support structure for holding the container.
Bei herkömmlichen Drehbehältern beziehungsweise Kannen für Ablage von Faserband, das von einer Spinnerei-Vorbereitungsmaschine ge¬ liefert wird, erfolgt die Bewegung der Mittel zum Zuführen des Faserbandes, die üblicherweise aus einem Paar von als Kalander bezeichneten Walzen bestehen, der Mittel zum epizykloidalen Able¬ gen des Bandes, die üblicherweise als Einlaufdrehteller bezeich¬ net werden, und der horizontalen Behälter-Trägerbasis durch einen einzigen mechanischen oder elektrischen Antrieb, der durch geei¬ gnete Transmissionssysteme alle Organe der Maschine antreibt. Es sind Drehbehälter bekannt, bei denen die horizontale Kannen-Trä¬ gerbasis autonom angetrieben wird. Es sind außerdem Drehbehälter bekannt, die keine horizontale Kannen-Trägerbasis besitzen. In diesem Fall erfolgt das Füllen der Kanne dadurch, daß man den Einlaufdrehteller kreisförmig über der Kanne rotieren läßt.In conventional rotating containers or cans for depositing sliver, which is supplied by a spinning preparation machine, the means for feeding the sliver, which usually consist of a pair of rollers called calenders, are used for the means for epicycloidal laying of the belt, which are usually referred to as infeed turntables, and the horizontal container support base by a single mechanical or electrical drive, which drives all the organs of the machine by means of suitable transmission systems. Rotary containers are known in which the horizontal can carrier base is driven autonomously. Rotary containers are also known which do not have a horizontal can support base. In this case, the jug is filled by rotating the inlet turntable in a circle over the jug.
Bei den bekannten AntriebsSystemen werden die Geschwindigkeit der Kalanderwalzen, des Einlaufdrehtellers und der Kannen-Trägerbasis bzw., falls eine solche nicht vorhanden ist, die kreisförmige Be¬ wegung des Einlaufdrehtellers bei der Projektierung festgelegt. Die Geschwindigkeitsverhältnisse sind nicht veränderbar, bzw. es bedarf hierzu komplizierter manueller Eingriffe in das Transmis¬ sionssystem zwischen dem Antrieb oder dem Elektromotor und den verschiedenen rotierenden Organen. Eine Anpassung der Funktion der Kanne an die Art des abzulegenden Faserbandes, dessen Kom¬ paktheit im Inneren der Kanne entweder unzureichend oder zu groß sein kann, ist deshalb zur Zeit nur dadurch möglich, daß man aufIn the known drive systems, the speed of the calender rolls, the infeed turntable and the can support base or, if such is not present, the circular movement of the infeed turntable is determined during project planning. The speed ratios cannot be changed, or complicated manual interventions in the transmission system between the drive or the electric motor and the various rotating organs are required for this. An adaptation of the function of the can to the type of sliver to be laid down, the compactness of which can be either insufficient or too large inside the can, is therefore currently only possible by

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der oben beschriebenen Art zu schaffen, bei der die vorgenannten Nachteile beseitigt sind und die sich einfach und schnell an die jeweiligen Bearbeitungserfordernisse anpassen läßt, wobei diese Anpassung automatisch auch während des normalen Arbeitsvorgangs möglich sein soll.The invention has for its object to provide a device of the type described above, in which the abovementioned disadvantages are eliminated and which can be easily and quickly adapted to the respective machining requirements, this adaptation should also be possible automatically during the normal working process.
Diese Aufgabe wird ≥rfindungsgemäß dadurch gelöst, daß die Mittel zum Zuführen des Faserbandes, die Mittel zum Ablegen des Faser¬ bandes und die drehbare Basis von einem ersten, einem zweiten bzw. einem dritten Elektromotor angetrieben werden, die mechnisch unabhängig voneinander sind.This object is achieved according to the invention in that the means for feeding the fiber sliver, the means for depositing the fiber sliver and the rotatable base are driven by a first, a second and a third electric motor which are mechanically independent of one another.
Die drei Elektromotoren sind vorzugsweise mit einer zentralen Steuereinheit verbunden, die Mittel zur Änderung der Geschwindig¬ keitsverhältnisse zwischen den Elektromotoren aufweist.The three electric motors are preferably connected to a central control unit which has means for changing the speed relationships between the electric motors.
Diese Änderung kann entweder vor dem Beginn des Kannen-Füllzyklus in Anpassung an den Typ des der Kanne zugeführten Bandes erfolgen oder während des Betriebs der sich drehenden Drehkanne in der Weise, daß die Kompaktheit der Windungen und die Regelmäßigkeit des abgelegten Bandes im wesentlichen konstant gehalten werden.This change can be made either before the start of the can filling cycle to suit the type of belt being fed to the can, or during the operation of the rotating rotary can in such a way that the compactness of the coils and the regularity of the deposited strip are kept substantially constant .
Die Mittel zur Änderung der Geschwindigkeitsverhältnisse zwischen den Elektromotoren umfassen vorzugsweise einen dem ersten Elek¬ tromotor zugeordneten ersten Tachodynamo, der über eine erste Re¬ glervorrichtung den zweiten Elektromotor steuern kann, sowie ei¬ nen dem zweiten Elektromotor zugeordneten zweiten Tachodynamo, der über eine zweite Reglervorrichtung den dritten Elektromotor steuern kann.The means for changing the speed ratios between the electric motors preferably comprise a first tachodynamo assigned to the first electric motor, which can control the second electric motor via a first controller device, and a second tachodynamo assigned to the second electric motor, which taps via a second controller device can control the third electric motor.

Die Bandablagevorrichtung 10 umfaßt weiterhin in bekannter Weise einen Einlaufdrehteller 14 mit vertikaler Achse, der eine Riemen¬ scheibe 14a aufweist, um die ein Riemen 16 für die Übertragung der Antriebsbewegung geschlungen ist, sowie eine untere Platte 14b, die in der gleichen Ebene zu einer festen Platte 18 angeord¬ net ist, die sich über einem an der Oberseite offenen Behälter 20, der sog. Spinnkanne, befindet. Diese Kanne 20 wird von der (nicht dargestellten) Tragkonstruktion der Bandablagevorrichtung getragen. Der Einlaufdrehteller 14 besitzt einen geneigt angeord¬ neten Bandkanal 15 mit einer im Bereich der Kalanderwa'lzen 12 an¬ geordneten Eingangsöffnung 15a und einer im Bereich der drehbaren Platte 14b in einer in bezug auf die vertikale Achse des Einlauf-The tape storage device 10 further comprises, in a known manner, an inlet turntable 14 with a vertical axis, which has a belt pulley 14a around which a belt 16 is wound for transmitting the drive movement, and a lower plate 14b, which in the same plane forms a fixed one Plate 18 is arranged, which is located above a container 20 open at the top, the so-called spinning can.

The can 20, which can be equipped in a manner known per se with a movable base 20a, which is pressed upwards by a helical spring S, is carried by a base 22, the so-called can plate, which can be rotated about a vertical axis which coincides with the axis of the cylindrical can 20.
Die Kalanderwalzen 12 werden von einem ersten Elektromotor 24 an¬ getrieben, der mit einem Tachodynamo 24a ausgestattet ist, der über eine erste Reglervorrichtung 26 einen zweiten Elektromotor 28 speisen kann. Dieser besitzt eine Antriebsriemenscheibe 29 für den Antrieb des Treibriemens 16 zum Drehen des Einlaufdrehtellers 14. Auch dem zweiten Elektromotor 28 ist ein Tachodynamo 28a zu¬ geordnet, der über eine zweite Reglervorrichtung 30 einen dritten Elektromotor 32 speisen kann, der seinerseits über eine Antriebs- riemenscheibe 32a und einen Treibriemen 33 den Kannenteller 22 drehen kann.The calender rolls 12 are driven by a first electric motor 24, which is equipped with a tachodynamo 24a, which can feed a second electric motor 28 via a first regulator device 26. This has a drive pulley 29 for driving the drive belt 16 for rotating the inlet turntable 14. Also assigned to the second electric motor 28 is a tachodynamo 28a, which can feed a third electric motor 32 via a second regulator device 30, which in turn uses a drive pulley 32a and a drive belt 33 can turn the can plate 22.
Die Geschwindigkeit des ersten Elektromotors wird mit Hilfe einer auch als "Master" bezeichneten Hilfsreglervorrichtung 34 mit ei¬ ner Zuführungsgeschwindigkeit des Faserbandes N korreliert. Die Hilfsreglervorrichtung 34 ist zwischen dem ersten Motor und der Einspeisung des Bandes N aus der Spinnereivorbereitungsmaschine M angeordnet.The speed of the first electric motor is correlated with the aid of an auxiliary control device 34, also referred to as the "master", with a feed speed of the sliver N. The auxiliary regulator device 34 is arranged between the first motor and the feed of the strip N from the spinning preparation machine M.
Eine erste Regelung der Bandablagevorrichtung 10 ist durch Ein¬ wirkung auf den Master 34 möglich. Sie erfolgt in Relation zu dem Durchmesser und dem Typ des Bandes (schwer oder leicht), das den Kalanderwalzen 12 zugeführt wird, und ermöglicht eine korrekte Zuführung und Ablage des Bandes N am Ausgang der Maschine und dem Eingang der Kanne 20.A first regulation of the tape storage device 10 is possible by acting on the master 34. It is in relation to the diameter and the type of belt (heavy or light) that is fed to the calender rolls 12 and enables the belt N to be correctly fed and deposited at the machine outlet and the can 20 inlet.
Es ist weiterhin möglich, die Geschwindigkeitsverhältnisse zwi¬ schen dem ersten Motor 24 und dem zweiten Motor 28, und zwischen dem zweiten Motor 28 und dem dritten Motor 32 in Abhängkeit vonIt is also possible to determine the speed relationships between the first motor 24 and the second motor 28 and between the second motor 28 and the third motor 32 as a function of
ERSATZBLATT dem Typ des Bandes N zu variieren. Diese Regelung kann durch Be¬ tätigung von an einer zentralen Steuereinheit 36 angeordneten Po¬ tentiometern P manuell oder auch automatisch nach einem vorbe¬ stimmten Programm, das in der zentralen Steuereinheit 36 gespei¬ chert ist, erfolgen.REPLACEMENT LEAF to vary the type of tape N. This regulation can be carried out by actuating potentiometers P arranged on a central control unit 36 manually or also automatically according to a predetermined program which is stored in the central control unit 36.
Durch geeignete Wahl der den Reglervorrichtungen 26 und 30 zu¬ geordneten Regelungsfunktionen kann die Geschwindigkeit des zwei¬ ten Motors 28 variiert werden, wobei die Geschwindigkeit des dritten Motors 32 unverändert beibehalten wird.The speed of the second motor 28 can be varied by suitable selection of the control functions assigned to the control devices 26 and 30, the speed of the third motor 32 being maintained unchanged.
Es ist weiterhin möglich, die Drehbehältervorrichtung 10 so zu programmieren, daß die Geschwindigkeiten des zweiten und des dritten Motors 28 bzw. 32 im Laufe der Zeit (kontinuierlich oder stufenweise) verändert werden, um ein übermäßiges Verdichten des in Windungen abgelegten Bandes zu vermeiden.It is also possible to program the rotary container assembly 10 so that the speeds of the second and third motors 28 and 32 change over time (continuously or in stages) to avoid over-compressing the coiled tape.
Beispielsweise wurden in einem Fall optimale Ergebnisse erzielt, indem die Reglervorrichtungen 26, 30 die Geschwindigkeiten um 15 % gegenüber dem Nennwert der Drehgeschwindigkeit erhöhten, wo¬ bei Motoren verwendet wurden, wie sie von der Firma SOPREL unter der Typenbezeichnung ROTODRIVE hergestellt werden und die mit Ta¬ chodynamos des Modells ROS3B30/04A2 und des Modells ROS3D30/04 mit elektronischen Steuerkarten ausgestattet sind. In einem ande¬ ren Fall wurden die Geschwindigkeiten des zweiten und des dritten Motors 28 bzw. 32 um 10 % von einer niedrigeren Geschwindigkeit auf die Normalgeschwindigkeit erhöht.For example, optimal results were achieved in one case by regulating devices 26, 30 increasing the speeds by 15% compared to the nominal value of the rotational speed, using motors such as those manufactured by SOPREL under the type designation ROTODRIVE and which are designated Ta ¬ Chodynamos of the model ROS3B30 / 04A2 and the model ROS3D30 / 04 are equipped with electronic control cards. In another case, the speeds of the second and third motors 28 and 32 were increased by 10% from a lower speed to the normal speed.
Es ist weiterhin die Verwendung eines Programms zur Steuerung der drei Elektromotoren vorgesehen, das nach einer vorbestimmten Zeit, die der Zykluszeit zum Füllen der Kanne 20 entspricht, die Geschwindigkeit der Kalanderwalzen 12 rasch auf einen bestimmten Wert einstellbar erhöht, so daß sie das Band N abreißen. Dadurch kann das Band einem leeren Behälter zugeführt werden, der als nächster auf die Bandablagevorrichtung 10 geladen wird.The use of a program for controlling the three electric motors is also provided which, after a predetermined time, which corresponds to the cycle time for filling the can 20, increases the speed of the calender rolls 12 so that they can be torn off, so that they tear off the strip N. . As a result, the tape can be fed to an empty container which is next loaded onto the tape storage device 10.
ERSATZBLATT Die Möglichkeit zur unabhängigen Regelung der Geschwindigkeiten der drei Elektromotoren der Bandablagevorrichtung 10 erlaubt es, die Vorrichtung mit einem Gerät zum Analysieren des Bandes N zu verbinden, das die Unregelmäßigkeiten beispielsweise als Abwei¬ chung vom Mittelwert der Banddicke erfaßt. Um ein Band so gleich¬ förmig wie möglich in die Kanne 20 abzulegen, ist es möglich, die erfindungsgemäße Bandablage-Anordnung direkt durch ein solches Analysegerät steuern zu lassen, das zwischen der Textilmaschine M und dem Drehbehälter angeordnet ist.REPLACEMENT LEAF The possibility of independently regulating the speeds of the three electric motors of the tape storage device 10 allows the device to be connected to a device for analyzing the tape N, which detects the irregularities, for example as a deviation from the mean value of the tape thickness. In order to deposit a tape as uniformly as possible into the can 20, it is possible to have the tape storage arrangement according to the invention controlled directly by such an analysis device which is arranged between the textile machine M and the rotating container.
Die Wirkungen der vorliegenden Erfindung erstrecken sich selbst¬ verständlich auch auf Vorrichtungen, die von demselben erfin¬ dungsgemäßen Konzept Gebrauch machen. Obwohl als Ausführungsbei- spiel ein Drehbehälter mit zentralen stationär angeordneten Ka¬ landerwalzen beschrieben wurde, ist das Erfindungskonzept bei¬ spielsweise auch anwendbar bei Drehbehältern mit umlaufenden Ka¬ landerwalzen, bei Drehbehältern mit sogenannten Zweifachwicklern oder Doppel-Zweifachwicklern, bei Drehbehältern mit Vorrichtungen zum automatischen Kannenwechsel und bei Drehbehältern, die auf keine drehbare horizontale Basis gestellt sind und bei denen der Einlaufdrehteller kreisförmig über der Kanne bewegt wird.The effects of the present invention naturally also extend to devices which make use of the same concept according to the invention. Although a rotary container with central stationary calender rollers has been described as an exemplary embodiment, the inventive concept can also be used, for example, with rotary containers with rotating calender rollers, with rotary containers with so-called double winders or double double winders, and with rotary containers with devices for automatic can change and for rotary containers that are not placed on a rotatable horizontal base and in which the inlet turntable is moved in a circle over the jug.
Anstelle von Drehbehältern können auch sogenannte Flachkannen treten, denen für die Bandablage statt einer Drehbewegung eine transversale Bewegung erteilt wird. In diesem Falle entspricht der Antriebsmotor für eine transversale Bewegung der Basis 22 dem Motor 32. Auch hier ist es von Vorteil, wann die transversale Be¬ wegung der Kanne entsprechend einer optimalen Bandablage gesteu¬ ert werden kann.Instead of rotating containers, it is also possible to use so-called flat cans, which are given a transverse movement instead of a rotating movement for the tape storage. In this case, the drive motor for a transverse movement of the base 22 corresponds to the motor 32. Here, too, it is advantageous when the transverse movement of the can can be controlled in accordance with an optimal belt deposit.
Es ist nicht in jedem Fall erforderlich, daß für die Kalanderwal¬ zen 12 ein spezieller Motor 24 vorgesehen sein muß. Die Kalander¬ walzen 12 können auch in den Antrieb der Spinnereivorbereitungs- maschine integriert sein, so daß der Motor 24 gleichbedeutend mit dem Antriebsmotor der Spinnereivorbereitungsmaschine zu verstehen ist. Zu Abänderung der gezeigten Ausführung kann es auch zweckmäßig sein, den Tachodynamo (24a) nicht dem Elektromotor 24, sondern direkt den Kalanderwalzen 12 zuzuordnen. Diese Ausführung bietet sich beispielsweise an, wenn der Antrieb der Kalanderwalzen 12 in den Antrieb der Spinnereivorbereitungsmaschine integriert ist.It is not necessary in every case that a special motor 24 must be provided for the calender rolls 12. The calender rolls 12 can also be integrated in the drive of the spinning preparation machine, so that the motor 24 is to be understood as meaning the drive motor of the spinning preparation machine. To change the embodiment shown, it may also be expedient not to assign the tachodynamo (24a) to the electric motor 24, but rather directly to the calender rolls 12. This version is useful, for example, if the drive of the calender rolls 12 is integrated in the drive of the spinning preparation machine.
