Definitions
- the invention relates to a roving machine of the type specified in the preamble of claim 1.
- a roving machine is known in which the individual units i.e. the drafting systems, the wings, the bobbins, the bobbin carriages, etc. of all spinning units are driven by one motor each.
- This flyer has the advantage over conventional roving machines that the drive motors can be adapted to the movement conditions of the associated functional units with regard to operating power, speed range or the like, which considerably simplifies the control and also the design of the gear trains.
- this machine version also has the disadvantage that in the event of a malfunction or failure of only one individual unit and / or when changing the bobbin, the entire machine with all drives must be switched off.
- the invention has for its object to largely avoid standstills of the entire roving machine when the spinning process in individual spinning units is interrupted.
- the roving machine is subdivided into sections that are operable independently of one another, with the functional units of the same type contained in each section being assigned a separate drive which can be controlled independently as a function of the other drives of the section in question. All drives are advantageously connected to a master computer superordinate to the sections, and each section can have its own electronic control unit, if applicable.
- the invention brings i.a. the advantage that the individual sections of the roving machine can work autonomously, since they are linked to an overall machine only by the central control computer. If a unit in a spinning unit malfunctions, only the associated section has to be switched off or shut down, all spinning units of the other sections being able to continue working normally. Over longer operating times, this results in a significant reduction in dead times and a corresponding increase in the overall performance of the machine.
- the additional effort caused by the increased number of drive motors is compensated for by simplifying the gear trains and by improving the control behavior of the individual units.
- the energy consumption is reduced by the reduced number of mechanical assemblies and the stopping of the functional units in sections.
- each section SE1 to SEn contains a predetermined number of spinning units S1 to S12, each spinning unit S1 to S12 having a spinning wing SF, at least one spool SP and a drafting system with rollers SW1, SW2 and SW3.
- the coils SP of each section SE1, SE2 and SEn are each arranged side by side on a common coil carriage SPW.
- the individual units SF, SP, SW1, SW2 and SW3 of the first spinning unit S1 of the first section SE1 are identified by hatching in FIG. 1.
- the individual units SF, SP, SW1, SW2 and SW3 for the spinning units S1 to S12 of each section SE1 to SEn are each driven together by a drive motor A11 to A16 or A21 to A26 or An1 to An6.
- a drive motor A13 or A23 or An3 is assigned to each coil carriage SPW of each section SE1 to SEn.
- the drive motor A11 thus drives the spinning wings SF of all spinning units S1 to S12 of section SE1.
- the spools SP and the drafting rollers SW1, SW2 and SW3 of section SE1 are each jointly driven by the associated drive motors A12, A14, A15, A16.
- each section SE1 to SEn has its own operating computer B1 to Bn, from which the drive motors A11 to A16 ... An1 to An6 are controlled.
- the operating computers B1 to Bn are connected to a common master computer LR.
- This structure described can be easily adapted to the conditions on the prespinning machine in accordance with the number of spinning units and their units to be driven.
- the operating computers B1 to Bn calculate the necessary textile-technological values for the spinning units of each section and determine the respective electrical actuating variables for the drive motors.
- the operating computers B1 to Bn use appropriate sensors on the spinning units or their assemblies to record, for example, the start and end of the bobbin build-up, the causes of necessary process corrections, such as Irregularities in the sliver run, and process interruptions, such as broken sliver or sliver, and then determine the necessary manipulated variables in accordance with the spinning laws. They also control the resumption of the process after an interruption.
- the activity of the operating computers B1 to Bn is coordinated by the control computer LR, into which the necessary textile-technological output data for the respective spinning process are entered manually or by means of a data carrier.
- the master computer LR processes this data and forwards command data or signals to the computers B1 to Bn. Corrections and interventions by the operating personnel are also carried out via the control computer LR, which can also be equipped with a higher level of competence in order to take on additional tasks of the operating computers B1 to Bn. In this case, simple control units can be used instead of the operating computers B1 to Bn.

- each frame GB there is a coil carriage SPW, which carries the coils SPn of this section, driven by the common motor An2, and moves vertically in guides, not shown, for executing the laying movement of the drive motor An3 via a suitable gear.
- a support beam TG is also fastened, on which the spinning wings SF of the section are mounted, which are driven together by the drive motor An1 via the gear train shown in broken lines.
- the drafting system of each spinning unit contains three roller pairs SW1, SW2 and SW3, the individual roller pairs SW1, SW2 and SW3 of all spinning units S1 to S12 of Sekton SEn being driven by motors An4, An5 and An6, respectively. The same applies to the neighboring sections.

Description
Die Erfindung betrifft eine Vorspinnmaschine der im Oberbegriff des Patentanspruchs 1 angegebenen Gattung.The invention relates to a roving machine of the type specified in the preamble of
Bei herkömmlichen auch als Flyer bezeichneten Vorspinnmaschinen werden die verschiedenen Aggregate aller Spinneinheiten, wie beispielsweise die Streckwerke, die Flügel, die Spulenwagen usw., von einem gemeinsamen Motor über verschiedenartige Getriebezüge angetrieben. Trotz gewisser energetischer und antriebstechnischer Vorzüge dieses Maschinentyps, besteht ein grundsätzlicher Nachteil darin, daß bei einer Störung oder einem Ausfall nur eines einzigen Aggregats in einer Spinneinheit, die gesamte Maschine stillgesetzt werden muß, bis der Schaden behoben ist. Dieser Nachteil wirkt sich entscheidend auf die Gesamtleistung der Maschine aus.In conventional pre-spinning machines, also known as flyers, the various units of all spinning units, such as the drafting systems, the wings, the bobbin wagons, etc., are driven by a common motor via various types of gear trains. Despite certain advantages in terms of energy and drive technology of this type of machine, there is a fundamental disadvantage that in the event of a malfunction or failure of only one unit in a spinning unit, the entire machine must be shut down until the damage is repaired. This disadvantage has a decisive impact on the overall performance of the machine.
Aus der DD-PS 217 832 ist eine Vorspinnmaschine bekannt, bei der die einzelnen Aggregate d.h. die Streckwerke, die Flügel, die Spulen, die Spulenwagen usw. aller Spinneinheiten von je einem Motor gemeinsam angetrieben werden. Dieser Flyer hat gegenüber den herkömmlichen Vorspinnmaschinen den Vorzug, daß die Antriebsmotoren hinsichtlich Betriebsleistung, Drehzahlbereich oder dgl. an die Bewegungsverhältnisse der zugehörigen Funktionsaggregate angepaßt werden können, was die Steuerung und auch die Auslegung der Getriebezüge wesentlich vereinfacht. Auch diese Maschinenausführung ist jedoch mit dem Nachteil behaftet, daß bei Störung oder Ausfall nur eines Einzelaggregats und/oder beim Spulenwechsel die gesamte Maschine mit allen Antrieben abgeschaltet werden muß.From DD-PS 217 832 a roving machine is known in which the individual units i.e. the drafting systems, the wings, the bobbins, the bobbin carriages, etc. of all spinning units are driven by one motor each. This flyer has the advantage over conventional roving machines that the drive motors can be adapted to the movement conditions of the associated functional units with regard to operating power, speed range or the like, which considerably simplifies the control and also the design of the gear trains. However, this machine version also has the disadvantage that in the event of a malfunction or failure of only one individual unit and / or when changing the bobbin, the entire machine with all drives must be switched off.
Der Erfindung liegt die Aufgabe zugrunde, bei Unterbrechung des Spinnvorgangs in einzelnen Spinneinheiten Stillstände der gesamten Vorspinnmaschine weitgehend zu vermeiden.The invention has for its object to largely avoid standstills of the entire roving machine when the spinning process in individual spinning units is interrupted.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in
Gemäß der Erfindung ist die Vorspinnmaschine in voneinander unabhängig funktionsfähige Sektionen unterteilt, wobei den in jeder Sektion enthaltenen Funktionseinheiten gleicher Art jeweils ein separater Antrieb zugeordnet ist, welcher in Abhängigkeit von den übrigen Antrieben der betreffenden Sektion selbständig angesteuert werden kann. Vorteilhaft sind alle Antriebe mit einem den Sektionen übergeordneten Leitrechner verbunden, wobei jede Sektion über eine eigene ggf. elektronische Steuereinheit verfügen kann.According to the invention, the roving machine is subdivided into sections that are operable independently of one another, with the functional units of the same type contained in each section being assigned a separate drive which can be controlled independently as a function of the other drives of the section in question. All drives are advantageously connected to a master computer superordinate to the sections, and each section can have its own electronic control unit, if applicable.
Die Erfindung bringt u.a. den Vorteil, daß die einzelnen Sektionen der Vorspinnmaschine autonom arbeiten können, da sie nur durch den zentralen Leitrechner zu einer Gesamtmaschine verknüpft sind. Bei einer Störung eines Aggregats in einer Spinneinheit muß daher nur die zugehörige Sektion abgeschaltet bzw. stillgesetzt werden, wobei alle Spinneinheiten der anderen Sektionen normal weiterarbeiten können. Über längere Betriebszeiten ergibt sich dadurch eine erhebliche Verminderung der Totzeiten und eine entsprechende Steigerung der Gesamtleistung der Maschine. Der durch die vergrößerte Anzahl an Antriebsmotoren bedingte Mehraufwand wird durch die Vereinfachung der Getriebezüge und durch ein verbessertes Steuerverhalten der Einzelaggregate kompensiert. Der Energieverbrauch reduziert sich durch die verrringerte Anzahl an mechanischen Baugruppen und das sektionsweise Stillsetzen der Funktionseinheiten. Die Bewegungsübertragung wird durch die verkürzten Übertragungswege zwischen den Antrieben und zugehörigen Aggregaten exakter, was zu einem exakteren Spulenaufbau führt. Infolge der Selbständigkeit der einzelnen Sektionen ist die Stellung der Flügel von Sektion zu Sektion unterschiedlich, so daß die Vorspinnmaschine insgesamt ruhiger läuft.The invention brings i.a. the advantage that the individual sections of the roving machine can work autonomously, since they are linked to an overall machine only by the central control computer. If a unit in a spinning unit malfunctions, only the associated section has to be switched off or shut down, all spinning units of the other sections being able to continue working normally. Over longer operating times, this results in a significant reduction in dead times and a corresponding increase in the overall performance of the machine. The additional effort caused by the increased number of drive motors is compensated for by simplifying the gear trains and by improving the control behavior of the individual units. The energy consumption is reduced by the reduced number of mechanical assemblies and the stopping of the functional units in sections. The transmission of motion becomes more precise due to the shortened transmission paths between the drives and the associated units, which leads to a more precise spool structure. Due to the independence of the individual sections, the position of the wings differs from section to section, so that the roving machine runs smoother overall.

Die Vorspinnmaschine nach Fig. 1 ist in n Sektionen SE1 bis SEn unterteilt, die funktionell voneinander getrennt sind und lediglich durch gemeinsame Gestellbaugruppen miteinander verbunden sein können. Jede Sektion SE1 bis SEn enthält eine vorbestimmte Anzahl an Spinneinheiten S1 bis S12, wobei zu jeder Spinneinheit S1 bis S12 ein Spinnflügel SF, mindestens eine Spule SP und ein Streckwerk mit Walzen SW1, SW2 und SW3 gehört. Bei dem in Fig. 1 dargestellten Ausführungsbeispiel sind die Spulen SP jeder Sektion SE1, SE2 bzw. SEn jeweils auf einem gemeinsamen Spulenwagen SPW nebeneinander angeordnet. Die einzelnen Aggregate SF, SP, SW1, SW2 und SW3 der ersten Spinneinheit S1 der ersten Sektion SE1 sind in Fig. 1 durch Schraffur gekennzeichnet.1 is divided into n sections SE1 to SEn, which are functionally separated from one another and can only be connected to one another by common frame assemblies. Each section SE1 to SEn contains a predetermined number of spinning units S1 to S12, each spinning unit S1 to S12 having a spinning wing SF, at least one spool SP and a drafting system with rollers SW1, SW2 and SW3. In the embodiment shown in FIG. 1, the coils SP of each section SE1, SE2 and SEn are each arranged side by side on a common coil carriage SPW. The individual units SF, SP, SW1, SW2 and SW3 of the first spinning unit S1 of the first section SE1 are identified by hatching in FIG. 1.
Die einzelnen Aggregate SF, SP, SW1, SW2 und SW3 für die Spinneinheiten S1 bis S12 jeder Sektion SE1 bis SEn werden von je einem Antriebsmotor A11 bis A16 bzw. A21 bis A26 bzw. An1 bis An6 jeweils gemeinsam angetrieben. Jedem Spulenwagen SPW jeder Sektion SE1 bis SEn ist jeweils ein Antriebsmotor A13 bzw. A23 bzw. An3 zugeordnet. Der Antriebsmotor A11 treibt somit die Spinnflügel SF aller Spinneinheiten S1 bis S12 der Sektion SE1 an. Entsprechend werden die Spulen SP und die Streckwerks-Walzen SW1, SW2 und SW3 der Sektion SE1 jeweils gemeinsam von den zugehörigen Antriebsmotoren A12, A14, A15, A16 angetrieben. Ferner verfügt jede Sektion SE1 bis SEn über einen eigenen Betriebsrechner B1 bis Bn, von dem die Antriebsmotoren A11 bis A16 ... An1 bis An6 angesteuert werden. Die Betriebsrechner B1 bis Bn sind an einen gemeinsamen Leitrechner LR angeschlossen.The individual units SF, SP, SW1, SW2 and SW3 for the spinning units S1 to S12 of each section SE1 to SEn are each driven together by a drive motor A11 to A16 or A21 to A26 or An1 to An6. A drive motor A13 or A23 or An3 is assigned to each coil carriage SPW of each section SE1 to SEn. The drive motor A11 thus drives the spinning wings SF of all spinning units S1 to S12 of section SE1. Correspondingly, the spools SP and the drafting rollers SW1, SW2 and SW3 of section SE1 are each jointly driven by the associated drive motors A12, A14, A15, A16. Furthermore, each section SE1 to SEn has its own operating computer B1 to Bn, from which the drive motors A11 to A16 ... An1 to An6 are controlled. The operating computers B1 to Bn are connected to a common master computer LR.
Diese beschriebene Struktur kann den Gegebenheiten an der Vorspinnmaschine entsprechend der Anzahl der Spinneinheiten und deren anzutreibenden Aggregaten problemlos angepaßt werden.This structure described can be easily adapted to the conditions on the prespinning machine in accordance with the number of spinning units and their units to be driven.
Während des Betriebes der Vorspinnmaschine errechnen die Betriebsrechner B1 bis Bn die notwendigen textiltechnologischen Werte für die Spinneinheiten jeder Sektion und ermitteln daraus die jeweiligen elektrischen Stellgrößen für die Antriebsmotoren. Die Betriebsrechner B1 bis Bn erfassen über entsprechende Sensoren an den Spinneinheiten bzw. deren Aggregaten beispielsweise den Beginn und das Ende des Spulenaufbaus, die Ursachen für notwendige Prozeßkorrekturen, wie z.B. Unregelmäßigkeiten im Luntenlauf, und Prozeßunterbrechungen, wie Band- oder Luntenbruch, und ermitteln danach die notwendigen Stellgrößen in Übereinstimmung mit den Spinngesetzen. Sie steuern auch die Wiederaufnahme des Prozesses nach einer Unterbrechung.During operation of the pre-spinning machine, the operating computers B1 to Bn calculate the necessary textile-technological values for the spinning units of each section and determine the respective electrical actuating variables for the drive motors. The operating computers B1 to Bn use appropriate sensors on the spinning units or their assemblies to record, for example, the start and end of the bobbin build-up, the causes of necessary process corrections, such as Irregularities in the sliver run, and process interruptions, such as broken sliver or sliver, and then determine the necessary manipulated variables in accordance with the spinning laws. They also control the resumption of the process after an interruption.
Die Tätigkeit der Betriebsrechner B1 bis Bn wird durch den Leitrechner LR koordiniert, in den die notwendigen textiltechnologischen Ausgangsdaten für den jeweiligen Spinnprozeß manuell oder mittels Datenträger eingegeben werden. Der Leitrechner LR verarbeitet diese Daten und gibt Befehlsdaten bzw. -signale an die Rechner B1 bis Bn weiter. Auch Korrekturen und Eingriffe des Bedienpersonals erfolgen über den Leitrechner LR, der auch mit einer höheren Kompetenz ausgestattet sein kann, um zusätzlich Aufgaben der Betriebsrechner B1 bis Bn zu übernehmen. In diesem Fall können statt der Betriebsrechner B1 bis Bn einfache Steuereinheiten eingesetzt werden.The activity of the operating computers B1 to Bn is coordinated by the control computer LR, into which the necessary textile-technological output data for the respective spinning process are entered manually or by means of a data carrier. The master computer LR processes this data and forwards command data or signals to the computers B1 to Bn. Corrections and interventions by the operating personnel are also carried out via the control computer LR, which can also be equipped with a higher level of competence in order to take on additional tasks of the operating computers B1 to Bn. In this case, simple control units can be used instead of the operating computers B1 to Bn.
In Fig. 2 sind eine Sektion SEn vollständig und die beiden seitlich angrenzenden Sektionen SEn-1 und SEn+1 teilweise in perspektivischer schematischer Ansicht dargestellt. Gleiche Bauteile zu Fig. 1 sind mit gleichen Bezugszeichen und entsprechend geänderten Indizes versehen. Wie dargestellt enthält jede Sektion ein eigenes Gestell GB, dessen Seitenwände dicht nebeneinander angeordnet und durch geeignete Verbindungsmittel aneinander befestigt werden können, wie es für die rechte Seitenwand der mittleren Sektion SEn dargestellt ist. In jedem Gestell GB ist ein Spulenwagen SPW angeordnet, der die vom gemeinsamen Motor An2 angetriebenen Spulen SPn dieser Sektion trägt und zur Ausführung der Verlegebewegung vom Antriebsmotor An3 über ein geeignetes Getriebe vertikal in nicht dargestellten Führungen verfährt. Im Gestell GB ist ferner ein Tragholm TG befestigt, an dem die Spinnflügel SF der Sektion gelagert sind, die gemeinsam von dem Antriebsmotor An1 über den strickpunktiert dargestellten Getriebezug angetrieben werden. Das Streckwerk jeder Spinneinheit enthält drei Walzenpaare SW1, SW2 und SW3, wobei die einzelnen Walzenpaare SW1 bzw. SW2 bzw. SW3 aller Spinneinheiten S1 bis S12 der Sekton SEn jeweils von den Motoren An4 bzw. An5 bzw. An6 angetrieben werden. Entsprechendes gilt für die benachbarten Sektionen.2 shows a section SEn completely and the two laterally adjacent sections SEn-1 and SEn + 1 are partially shown in a perspective schematic view. The same components as in FIG. 1 are provided with the same reference symbols and correspondingly changed indices. As shown, each section contains its own frame GB, the side walls of which can be arranged close to one another and fastened to one another by suitable connecting means, as is shown for the right side wall of the middle section SEn. In each frame GB there is a coil carriage SPW, which carries the coils SPn of this section, driven by the common motor An2, and moves vertically in guides, not shown, for executing the laying movement of the drive motor An3 via a suitable gear. In the frame GB, a support beam TG is also fastened, on which the spinning wings SF of the section are mounted, which are driven together by the drive motor An1 via the gear train shown in broken lines. The drafting system of each spinning unit contains three roller pairs SW1, SW2 and SW3, the individual roller pairs SW1, SW2 and SW3 of all spinning units S1 to S12 of Sekton SEn being driven by motors An4, An5 and An6, respectively. The same applies to the neighboring sections.
Die Erfindung ermöglicht eine optimale Anpassung der Vorspinnmaschinen an örtliche Gegebenheiten ebenso wie an wechselnden Leistungsbedarf. So können die einzelnen Sektionen nicht nur nebeneinander, sondern auch gegeneinander winkelversetzt und/oder insel- bzw. kreisförmig angeordnet werden, um besonderen betrieblichen bzw. räumlichen Gegebenheiten Rechnung zu tragen. Ferner lassen sich bestehende Maschinen auf einfache Weise auf höhere Leistung nachrüsten, indem eine oder mehrere Sektionen einfach angebaut und ihre Betriebssteuerungen bei Bedarf an den Leitrechner angeschlossen werden.The invention enables optimal adaptation of the roving machines to local conditions as well as to changing power requirements. In this way, the individual sections can be arranged not only next to one another, but also at an angle to one another and / or arranged in an island or in a circle, in order to take into account special operational or spatial conditions. Furthermore, existing machines can easily be upgraded to higher performance Retrofit by simply attaching one or more sections and connecting their operating controls to the host computer if required.
