Description

Die Erfindung betrifft ein Informationssystem innerhalb eines Verbundes zwischen je einer oder mehreren Spinn- und Spulmaschinen, in dem von den Spinnmaschinen erzeugte Kopse unterschiedlicher Garnpartien einzeln gemeinsam mit je einer Palette als Transporteinheit den Spulmaschinen oder Spulmaschinenabschnitten zugeführt werden, wobei die Transporteinheiten codiert sind.The invention relates to an information system within a network between one or more spinning and winding machines, in which cops of different yarn sections produced by the spinning machines are individually fed to the winding machines or winding machine sections together with a pallet as a transport unit, the transport units being coded.

Durch die DE-OS 17 85 329 ist es bekannt, in einem Verbund zwischen mehreren Spinn- und Spulmaschinen verschiedene Garnpartien zu verarbeiten. Dabei ist auch beschrieben, die Spulmaschinen in verschiedene Abschnitte aufzuteilen, die die Kopse aus den unterschiedlichen Garnpartien verarbeiten sollen. Diese Kopse werden durch ein Zuführförderband diesen Spulabschnitten zugeführt, welches Träger für einzelnen Kopse besitzt. Diese Träger besitzen Codierungen, die ein Zuführen der Kopse in den betreffenden Spulabschnitt sichern.From DE-OS 17 85 329 it is known to process different batches of yarn in a network between several spinning and winding machines. It is also described to divide the winding machines into different sections, which are to process the cops from the different yarn sections. These cops are fed to these winding sections by a feed conveyor belt which has carriers for individual cops. These carriers have codes that ensure that the cops are fed into the relevant winding section.

Eine ähnliche Vorrichtung, bei der die Einzelträger für die Kopse Codierungen aufweisen, beschreibt die DE-OS 33 08 171. Entsprechend der Trägercodierungen werden hier Weichen gesteuert, die ebenfalls die Zuführung zum jeweiligen Spulabschnitt bewirken.DE-OS 33 08 171 describes a similar device in which the individual carriers have codings for the cops. Points are controlled here in accordance with the carrier codings, which likewise effect the feed to the respective winding section.

In der CH-PS 410 718 ist ein Verfahren beschrieben, die Hülsen der Kopse so zu kennzeichnen, daß später die Spinnstelle erkannt werden kann, auf der der jeweilige Kops hergestellt wurde. Auf diese Weise war es möglich, zum Beispiel an der Spulmaschine bei häufig auftretenden Fadenbrüchen Rückschlüsse auf die Spinnstelle zu ziehen, um entsprechend Abhilfe zu schaffen.In CH-PS 410 718 a method is described to mark the sleeves of the cops in such a way that the spinning position on which the respective cop was produced can be recognized later. In this way it was possible, for example, on the winder frequently occurring thread breaks draw conclusions about the spinning position in order to remedy the situation accordingly.

Durch die DE 37 42 112 A ist weiter eine Transporteinrichtung für Textilspulen bekannt, die Transportelemente mit codierbaren Informationsträgern aufweist. Die auf den Informationsträgern enthaltenen Hinweise lassen Rückschlüsse auf den jeweiligen Herstellungsort der Spule zu, so daß die in einer nachgeschalteten Prüfstation als "out of standard" erkannten Spulen einer bestimmten Spulstelle zugeordnet werden können. Auf diese Weise können fehlerhaft arbeitende Spulstellen leicht identifiziert werden. Eine Unterscheidung hinsichtlich unterschiedlicher Garnpartien ist bei dieser bekannten Einrichtung nicht vorgesehen.From DE 37 42 112 A a transport device for textile bobbins is also known which has transport elements with codable information carriers. The information contained on the information carriers allows conclusions to be drawn about the respective place of manufacture of the spool, so that the spools recognized as "out of standard" in a downstream test station can be assigned to a specific spool position. In this way, incorrectly working winding units can be easily identified. A distinction with regard to different yarn sections is not provided in this known device.

Die Aufgabe der Erfindung besteht darin, innerhalb eines Verbundes zwischen Spinn- und Spulmaschinen die Erkennung der Partie und der Herkunft der Kopse zu verbessern.The object of the invention is to improve the detection of the batch and the origin of the cops within a network between spinning and winding machines.

Diese Aufgabe wird erfindungsgemäß durch den Anspruch 1 gelöst. Die Erfindung ist durch die Ansprüche 2 bis 11 vorteilhaft weitergebildet.This object is achieved by claim 1. The invention is advantageously further developed by claims 2 to 11.

Das erfindungsgemäße Informationssystem ermöglicht sowohl die partiegerechte Verarbeitung von Kopsen als auch die Identifikation der jeweiligen Spinnstelle, um bei erkannter schlechter Kopsqualität unmittelbar auf die Spinnstelle einwirken zu können, an der diese Kopse hergestellt wurden. Damit sichert die Erfindung bei einer hohen Flexibilität des Verbundes gleichzeitig eine effektive Qualitätsüberwachung. Vorteilhaft ist außerdem die getrennte Codierung. So kann es durchaus vorkommen, daß bei der Zuführung der Kopse zu den Spulstellen im Bereich des gemeinsamen Zuführweges die Einheit Kops/Palette, zum Beispiel durch Eingriff von Hand, getrennt wird. Da die Partie ausschließlich an der Hülsenfarbe erkannt wird, kann auch bei einem Austausch der jeweiligen Palette auf die der Kops aufgesetzt ist, keine Zuführung in einen Spulabschnitt für eine andere Partie erfolgen. Das ist deshalb von besonderer Bedeutung, weil das Umspulen eines Kopses aus einer anderen Partie auf eine Kreuzspule erhebliche Folgen bei deren Weiterverarbeitung hat. Hinzu kommt, daß bei ohnehin für die verschiedenen Partien verwendeten Hülsen unterschiedlicher Farbe keine zusätzliche Kennzeichnung notwendig ist, um deren Steuerung zu bewirken.The information system according to the invention enables both cops to be processed in accordance with the game and the identification of the respective spinning station in order to be able to act directly on the spinning station at which these cops were produced if poor cop quality is recognized. The invention thus ensures effective quality monitoring at the same time as the network is highly flexible. Separate coding is also advantageous. So it can happen that the cop / pallet unit is separated, for example by manual intervention, when the cops are fed to the winding units in the area of the common feed path. Since the batch is only recognized by the color of the tube, even if the respective pallet on which the cop is placed is not replaced, it cannot be fed into a winding section for another batch. This is particularly important because the rewinding of a cop from another batch onto a cheese has significant consequences in its further processing. In addition, in the case of sleeves of different colors used for the different batches, no additional identification is necessary in order to control them.

Der in den Fig. 1 und 2 dargestellte Verbund zwischen einer Spinnmaschine 1 und einer Spulmaschine 7 ist eine vereinfachte Darstellung. Nach dieser Darstellung wird von jeder der beiden Spinnmaschinenseiten je eine Garnpartie hergestellt. Beim Doffen werden die von den Spinnstellen 2 erzeugten Kopse 4 auf ein mit Aufsteckdornen versehenes Förderband 3 aufgesetzt. Analog erfolgt das Aufsetzen der auf den Spinnstellen 2′ erzeugten Kopse 4′ auf die Aufsteckdorne des Förderbandes 3′. Diese Förderbänder 3 beziehungsweise 3′ werden durch Motoren 25 beziehungsweise 25′ auf Basis von spulmaschinenseitigen Anforderungssignalen intermittierend angetrieben. Die Zuführung der jeweiligen Hülsen 5 beziehungsweise 5′ erfolgt über Rückführbänder 6 beziehungsweise 6′ zu Aufsetzeinrichtungen 39 beziehungsweise 39′. Das Aufsetzen erfolgt auf in der Zeichnung dargestellte Dorne des Förderbandes 3 beziehungsweise 3′.1 and 2 between a spinning machine 1 and a winding machine 7 is a simplified representation. According to this illustration, a yarn section is produced from each of the two sides of the spinning machine. When doffing, the cops 4 produced by the spinning stations 2 are placed on a conveyor belt 3 provided with arbors. Analogously, the attachment of the cops 4 'produced on the spinning stations 2' onto the arbors of the conveyor belt 3 '. These conveyor belts 3 and 3 'are driven intermittently by motors 25 and 25' based on request signals on the winder side. The respective sleeves 5 and 5 'are fed via return belts 6 and 6' to attachment devices 39 and 39 '. It is placed on the mandrels of the conveyor belt 3 or 3 'shown in the drawing.

An der Kopslieferstelle 24 werden die Kopse 4 beziehungsweise 4′ auf Paletten 33 aufgesetzt, die in einem geschlossenen spulmaschinenseitigen Kreislauf umlaufen.At the cops delivery point 24, the cops 4 and 4 'are placed on pallets 33, which circulate in a closed circuit on the dishwasher side.

Am vorderen Ende der Förderbänder 3 beziehungsweise 3′ sind Zähleinrichtungen 26 beziehungsweise 26′ angeordnet. Diese Zähleinrichtungen 26 beziehungsweise 26′, zum Beispiel Schieberegister, sind auf die Anzahl der Spinnstellen 2 beziehungsweise 2′ geeicht. Sie beginnen also ihre Zählung nach Lieferung einer der Spinnstellenanzahl entsprechenden Zahl von Kopsen wieder mit 1. Dadurch können sie jeden Kops 4 beziehungsweise 4′ der Spinnstelle 2 beziehungsweise 2′ zuordnen, von der er hergestellt wurde. Nach dem Umsetzen des Kopses 4 beziehungsweise 4′, welcher die zugehörige Zähleinrichtung 26 beziehungsweise 26′ passiert hat, auf die bereitstehende Palette 33 wird diese in eine Lösch- und Codiereinrichtung 28 transportiert. Diese Lösch- und Codiereinrichtung 28 steht mit den Zähleinrichtungen 26 und 26′ in Verbindung. Nach dem Löschen der letzten Information vom vorangehenden Umlauf der Palette 33 auf dem mit ihr verbundenen Speicherchip 36 wird die von der jeweiligen Zähleinrichtung 26 beziehungsweise 26′ übermittelte Spinnstellennummer neu codiert.At the front end of the conveyor belts 3 and 3 'counting devices 26 and 26' are arranged. These counters 26 and 26 ', for example shift registers, are calibrated to the number of spinning stations 2 and 2'. They therefore begin their count again with the delivery of a number of cops corresponding to the number of spinning positions, so that they can assign each cop 4 or 4 'to the spinning position 2 or 2' from which it was manufactured. After moving the cop 4 or 4 ', which has passed the associated counting device 26 or 26', on the ready-made pallet 33, the latter is transported to an erasing and coding device 28. This erasing and coding device 28 is connected to the counting devices 26 and 26 '. After deleting the last information from the previous circulation of the pallet 33 on the memory chip 36 connected to it, the spinning station number transmitted by the respective counting device 26 or 26 'is re-encoded.

Statt der Lösch- und Codiereinrichtung 28 kann auch eine Leseeinrichtung 28′ zum Einsatz kommen. Die Paletten besitzen in diesem Fall eine feste Codierung. Die Leseeinrichtung 28′ erkennt diese Codierung, verbindet diese mit der von der jeweiligen Zähleinrichtung 26 beziehungsweise 26′ übermittelten Spinnstellennummer und sendet diese Information an eine Zentraleinheit 15. Diese Informationsverbindung ist durch eine unterbrochene Linie 15′ dargestellt.Instead of the erasing and coding device 28, a reading device 28 'can also be used. In this case, the pallets have a fixed coding. The reading device 28 'recognizes this coding, connects it to the spinning station number transmitted by the respective counting device 26 or 26' and sends this information to a central unit 15. This information connection is represented by a broken line 15 '.

Am Ende der Förderbänder 3 beziehungsweise 3′ können zusätzlich in der Zeichnung nicht dargestellte Speicher angeordnet sein. Vorteilhaft sind dann die Zähleinrichtungen 26 beziehungweise 26′ am der Kopslieferstelle 24 zugewandten Ende der Speicher angeordnet. In jedem Fall muß abgesichert sein, daß die Information über die Spinnstelle solange gespeichert ist, bis der jeweilige Kops 4 beziehungsweise 4′ mit der ihn tragenden Palette 33 an der Codiereinrichtung 28 oder Leseeinrichtung 28′ eintrifft.At the end of the conveyor belts 3 and 3 'can also be arranged in the drawing memory, not shown. The counting devices 26 or 26 'are then advantageously arranged at the end of the store facing the cops delivery point 24. In any case, it must be ensured that the information about the spinning station is stored until the respective cop 4 or 4 'with the pallet carrying it 33 arrives at the coding device 28 or reading device 28 '.

Nach Verlassen der Lösch- und Codiereinrichtung 28 beziehungsweise Leseeinrichtung 28′ gelangt der Kops 4 beziehungsweise 4′ durch eine Vorbereitungseinrichtung 31, in der das Fadenende für das Umspulen bereitgelegt wird. An einer beiden Kopsarten 4 und 4′ gemeinsamen Zuführbahn 9 ist ein Farbsensor 10 angeordnet. Dieser Farbsensor 10 erkennt die Farbe der jeweiligen Hülse 5 beziehungsweise 5′ des Kopses 4 beziehungsweise 4′. Da diese Farben jeweils für eine Partie gleich sind, ist mit diesem Farbsensor 10 auch gleichzeitig die Partie erkennbar. Dieser Farbsensor 10 steht mit einer Weiche 11 in Verbindung. Diese Weiche 11 steuert den jeweiligen Kops 4 beziehungsweise 4′ mit seiner Palette 33 in den für ihn bestimmten Spulabschnitt 8 beziehungsweise 8′ über getrennte Zuführbahnen 12 beziehungsweise 12′. Diese Zuführbahnen 12 beziehungsweise 12′, die vereinfacht dargestellt sind, können zum Beispiel aus selbständigen Umlaufbahnen oder auch aus einem reversierenden Band bestehen. Bei diesen Varianten handelt es sich um bekannte Speichereinrichtungen, die erforderlich sind, um Schwankungen der Spulgeschwindigkeiten auszugleichen. Beim Nachrücken eines Kopses 4 beziehungsweise 4′ mit Palette 33 in die Abspulstellung wird im Bereich der Bereitstellungsführungen zur Spulstelle ein Speicherplatz frei. In diesen Speicherplatz wird dann ein sich im Bereich des zugehörigen Zuführbandes 12 beziehungsweise 12′ zirkulierender Kops 4 beziehungsweise 4′ mit seiner Palette 33 eingeführt. Das kann zum Beispiel über Weichen erfolgen. Im Bereich der Spulstellen 8 beziehungsweise 8′ sind Zähleinrichtungen 32 angeordnet, die die Anzahl der Fadenbrüche pro Kops 4 beziehungsweise 4′ erkennen. Diese Zähleinrichtungen 32 stehen mit den entsprechenden Fadenüberwachungsorganen der Spulstelle in Verbindung. Bei Überschreitung einer vorgebbaren Fadenbruchanzahl je Kops wird von der jeweiligen Zähleinrichtung 32 ein Hebel 35 betätigt. Dieser Hebel hebt in diesem Falle einen Ring 34, der auf dem Dorn der Palette 33 aufgesteckt ist, um einen bestimmten Betrag aus. Dieser Ring 34 ist mindestens so schwer auf dem Dorn verschiebar, daß er durch das Eigengewicht des Kopses nicht wieder in Richtung Grundplatte der Palette 33 verschoben werden kann. Nach dem Austrag des Kopses 4 beziehungsweise 4′ aus der Spulstelle wird dieser zusammen mit der dazugehörigen Palette 33 auf eine gemeinsame Rückführbahn 13 geführt. An dieser Rückführbahn 13 ist nach der letzten Spulstelle ein Sensor 14 in Höhe der Ringe 34 angeordnet. Dieser Sensor erkennt, wenn ein Ring über seine normale Position nach oben geschoben ist. Dieser Sensor 14 steht in einer Wirkverbindung mit einer Leseeinrichtung 16.After leaving the erasing and coding device 28 or reading device 28 ', the cop 4 or 4' passes through a preparation device 31 in which the thread end is prepared for rewinding. On a two cops 4 and 4 'common feed path 9, a color sensor 10 is arranged. This color sensor 10 detects the color of the respective sleeve 5 or 5 'of the cop 4 or 4'. Since these colors are the same for each batch, this batch can also be used to identify the batch at the same time. This color sensor 10 is connected to a switch 11. This switch 11 controls the respective cop 4 or 4 'with its pallet 33 in the winding section 8 or 8' intended for it via separate feed paths 12 or 12 '. These feed paths 12 and 12 ', which are shown in simplified form, can for example consist of independent orbits or a reversing belt. These variants are known storage devices which are required to compensate for fluctuations in the winding speeds. When moving a cop 4 or 4 'with pallet 33 in the unwind position, a storage space is free in the area of the preparation guides to the winding station. In this storage space, a cop 4 or 4 'circulating in the area of the associated feed belt 12 or 12' is then inserted with its pallet 33. This can be done using switches, for example. In the area of the winding units 8 and 8 'counting devices 32 are arranged which recognize the number of thread breaks per cop 4 and 4'. These counting devices 32 are connected to the corresponding thread monitoring devices of the winding unit. When a predeterminable number of thread breaks per cop is exceeded, a lever 35 is actuated by the respective counting device 32. In this case, this lever lifts one Ring 34, which is attached to the mandrel of the pallet 33 to a certain amount. This ring 34 is at least so difficult to move on the mandrel that it cannot be moved back towards the base plate of the pallet 33 due to the weight of the cop. After the discharge of the cop 4 or 4 'from the winding unit, this is guided together with the associated pallet 33 onto a common return path 13. On this return path 13, a sensor 14 is arranged at the level of the rings 34 after the last winding point. This sensor detects when a ring is pushed up over its normal position. This sensor 14 is in operative connection with a reading device 16.

Wurde vom Sensor 14 erkannt, daß ein Ring 34 über der normalen Position liegt, tritt die Leseeinrichtung 16 in Funktion. Sie erkennt die Codierung auf dem Speicherchip 36. Diese Information wird an die Zentraleinheit 15 übermittelt, die dann die defekte Spulstelle anzeigt, die einen Kops 4 beziehungsweise 4′ erzeugt hat, der zu einer überdurchschnittlichen Fadenbruchzahl in der Spulstelle geführt hat.If the sensor 14 detects that a ring 34 is above the normal position, the reading device 16 comes into operation. It recognizes the coding on the memory chip 36. This information is transmitted to the central unit 15, which then indicates the defective winding unit, which has produced a cop 4 or 4 ', which has resulted in an above-average number of thread breaks in the winding unit.

Im Falle einer bleibenden Codierung der Palette 33 kann die Zentraleinheit diese Codierung der jeweiligen Spinnstelle zuordnen, da sie die entsprechende Information von der Leseeinrichtung 28′ erhalten hat. An der Rückführbahn 13 ist im Anschluß an die Leseeinrichtung 16 ein Sensor 17 für Restkopse angeordnet, der, wenn er feststellt, daß ein mit einem noch abspulbaren Fadenrest versehener Kops 4 beziehungsweise 4′ ankommt, eine Weiche 18 steuert, die diesen Kops 4 beziehungsweise 4′ in eine Rückführbahn 29 für Restkopse leitet. An dieser Rückführbahn 29 ist ebenfalls eine Vorbereitungseinrichtung 30 angeordnet. Nach der Weiche 18 ist eine Aufschiebeeinrichtung 19 für die Ringe 34 angeordnet, die diese Ringe wieder in ihre Normalposition nach unten verschiebt. Im schrägen Verlauf der Unterkante von vorteilhafterweise paarweise auf beiden Seiten der Rückführbahn 13 angeordneten Hebeln 37 sind Rollen 38 angeordnet, um ein leichtes Aufgleiten des jeweiligen Ringes 34 zu sichern. Diese Aufschiebeeinrichtung 19 kann selbstverständlich auch vor der Weiche 18 angeordnet werden, um ein mehrmaliges Erfassen des gleichen Kopses 4 beziehungssweise 4′ durch die Leseeinrichtung 16 auch ohne erneute Überschreitung der vorgegebenen Fadenbruchzahl zu vermeiden.In the event of permanent coding of the pallet 33, the central unit can assign this coding to the respective spinning station, since it has received the corresponding information from the reading device 28 '. On the return path 13, a sensor 17 for residual bobbins is arranged after the reading device 16, which, if it detects that a bobbin 4 or 4 'provided with a thread residue that can still be unwound, arrives, controls a switch 18 which beats these cops 4 and 4 respectively 'Leads into a return path 29 for residual cops. A preparation device 30 is also arranged on this return path 29. After the switch 18, a slide-on device 19 for the rings 34 is arranged, which moves these rings back down to their normal position. Advantageously in the oblique course of the lower edge Levers 37 arranged in pairs on both sides of the return path 13 have rollers 38 arranged to ensure that the respective ring 34 slides on easily. This slide-on device 19 can of course also be arranged in front of the switch 18 in order to avoid repeated detection of the same cop 4 or 4 'by the reading device 16 even without again exceeding the predetermined number of thread breaks.

Vor beziehungsweise an der Hülsenabzugsvorrichtung 21 ist ein weiterer Farbsensor 20 angeordnet, der über die Hülsenfarbe die entsprechende Partie erkennt. Er steuert dann die Hülsenabzugsvorrichtung 21 so, daß die Hülse auf das zugehörige Hülsenrückführband 6 beziehungsweise 6′ abgelegt wird.A further color sensor 20 is arranged in front of or on the sleeve take-off device 21, which detects the corresponding batch via the sleeve color. He then controls the sleeve removal device 21 so that the sleeve is deposited on the associated sleeve return belt 6 or 6 '.

Der Farbsensor 20 steht außerdem mit einer Steuereinheit 22 in Verbindung. Wenn der Sensor 23 die Ankunft einer leeren Pallette 33 an der Kopslieferstelle 24 erkennt, wird von der Steuereinheit 22 abgefragt, welcher Partie die letzte abgezogene Hülse 5 beziehungsweise 5′ zugehört. Über eine weitere Steuereinheit 27, die auch Bestandteil der Steuereinheit 22 sein kann, wird der Motor 25 beziehungsweise 25′ angesteuert, der das Förderband 3 beziehungsweise 3′ ansteuert, welches der Partie entspricht, der die letzte abgezogene Hülse 5 beziehungsweise 5′ angehört. Entsprechend wird auch von der Steuereinheit 22 die Kopslieferstelle 24 gesteuert.The color sensor 20 is also connected to a control unit 22. When the sensor 23 detects the arrival of an empty pallet 33 at the cops delivery point 24, the control unit 22 queries which part the last removed sleeve 5 or 5 'belongs to. About a further control unit 27, which can also be part of the control unit 22, the motor 25 or 25 'is controlled, which controls the conveyor belt 3 or 3', which corresponds to the lot that belongs to the last removed sleeve 5 or 5 '. Correspondingly, the cop delivery point 24 is also controlled by the control unit 22.
