- the present invention relates to a power supply for the winding units of a winding machine, which is a winding unit with a spindle drive, a sensor for speed and / or position of the spindle and a thread traversing device with a drive, the spindle drive and the thread traversing device being electronically connected to one another are synchronized.
- the winding unit also contains the so-called thread run, these are the components from the attachment for the bobbin to be rewound to the thread traversing device, for example a thread monitor and a thread brake or insulation.
- a plurality of up to 60 or more winding units or spindles is arranged in a common frame and forms a winding machine with a common control cabinet, which among other things contains the power supply for all winding units.
- An example of such a winding machine is the precision cross winder PW1 preciflex from Shurer Schweiter Mettler AG.
- Suitable winding units are described, for example, in EP-A-0 453 622, EP-A-0 829 444 and EP-A-0 838 422. If there is any during the operation of such If the winding unit comes to a power failure, the thread traversing device is at a standstill after a very short time silent, whereas the coil because of its usually relatively large Mass continues to rotate, during which time the thread is wound onto the bobbin in parallel becomes. When restarting, the wound position of these parallel turns must be can be peeled and cut by hand, which can be considerable Material loss means. In addition, this requires at each winding unit manual intervention takes a considerable amount of time, so that a Power failure negatively affects productivity.
- the invention is now to improve the known winding machines so that Power failures no longer with such serious and manual intervention by the operating personnel necessary consequences are connected. But that comes in itself obvious solution, namely equipping the winding machines with a conventional one Emergency generator that feeds the entire winder, for cost reasons alone out of the question. Apart from that, such an emergency generator would be because of the high Number of spindles too big and too heavy.
- the achievement of the object according to the invention is characterized in that a power storage device that can be activated automatically in the event of a power failure is provided, which on the one hand the sensor mentioned and on the other hand the drive of the thread traversing device powered so that the synchronism between the spindle drive and the thread traversing device is maintained.
- the arrangement according to the invention therefore maintains the synchronism between the spindle drive and thread traversing device until the bobbin comes to a standstill, so that Controlled thread laying also takes place while the bobbin is running out. If the power failure is short, where short here means that the power failure before standstill the coil is finished again, then it is bridged by the arrangement, if it is longer, then an orderly stopping of the winding unit and thus the winding machine is made possible.
- a second preferred embodiment of the power supply according to the invention is characterized in that the power storage device by a static uninterrupted Power supply is formed.

After this period, the UPS 17 is deactivated and the winder waiting for the power supply to return. As soon as this exists, behaves the winding machine turns on as with the main switch, i.e. the control the UPS 17 and the winding unit controls 2 initialize and the thread guide moves to the two end points of its traversing interval, for example.
Description
Die vorliegende Erfindung betrifft eine Stromversorgung für die Spulstellen einer Spulmaschine, welche ein Spulaggregat mit einem Spindelantrieb, einen Sensor für Drehzahl und/oder Position der Spindel und eine Fadenchangiereinrichtung mit einem Antrieb aufweisen, wobei der Spindelantrieb und die Fadenchangiereinrichtung miteinander elektronisch synchronisiert sind.The present invention relates to a power supply for the winding units of a winding machine, which is a winding unit with a spindle drive, a sensor for speed and / or position of the spindle and a thread traversing device with a drive, the spindle drive and the thread traversing device being electronically connected to one another are synchronized.
Die Spulstelle enthält neben dem Spulaggregat noch den sogenannten Fadenlauf, das sind die Komponenten von der Aufsteckung für die umzuspulende Spule bis zur Fadenchangiereinrichtung, also beispielsweise einen Fadenwächter und eine Fadenbremse oder Dämmung. Jeweils eine Mehrzahl von bis zu 60 oder mehr Spulstellen oder Spindeln ist in einem ge-meinsamen Gestell angeordnet und bildet eine Spulmaschine mit einem ge-meinsamen Schaltschrank, der unter anderem die Stromversorgung für alle Spulstellen enthält. Als Beispiel für eine solche Spulmaschine sei hier die Präzisions-Kreuzspulmaschine PW1 preciflex der Schärer Schweiter Mettler AG genannt.In addition to the winding unit, the winding unit also contains the so-called thread run, these are the components from the attachment for the bobbin to be rewound to the thread traversing device, for example a thread monitor and a thread brake or insulation. In each case a plurality of up to 60 or more winding units or spindles is arranged in a common frame and forms a winding machine with a common control cabinet, which among other things contains the power supply for all winding units. An example of such a winding machine is the precision cross winder PW1 preciflex from Schärer Schweiter Mettler AG.
Geeignete Spulaggregate sind beispielsweise in der gattungsbildenden EP-A-0 453 622, der EP-A-0 829 444 und der EP-A-0 838 422 beschrieben. Wenn es während des Betriebs eines derartigen Spulaggregats zu einem Netzausfall kommt, dann steht die Fadenchangiereinrichtung nach sehr kurzer Zeit still, wogegen die Spule wegen ihrer in der Regel relativ grossen Masse weiter rotiert, wobei während dieser Zeit der Faden auf die Spule parallel aufgewickelt wird. Beim Neustart muss dann die aufgewickelte Lage dieser parallelen Windungen von Hand abgezogen und abgeschnitten werden, was einen unter Umständen beträchtlichen Materialverlust bedeutet. Ausserdem erfordert dieser an jeder Spulstelle vorzunehmende manuelle Eingriff einen beachtlichen Zeitaufwand, so dass also ein Netzausfall die Produktivität negativ beeinflusst.Suitable winding units are described, for example, in EP-A-0 453 622, EP-A-0 829 444 and EP-A-0 838 422. If there is any during the operation of such If the winding unit comes to a power failure, the thread traversing device is at a standstill after a very short time silent, whereas the coil because of its usually relatively large Mass continues to rotate, during which time the thread is wound onto the bobbin in parallel becomes. When restarting, the wound position of these parallel turns must be can be peeled and cut by hand, which can be considerable Material loss means. In addition, this requires at each winding unit manual intervention takes a considerable amount of time, so that a Power failure negatively affects productivity.
Durch die Erfindung sollen nun die bekannten Spulmaschinen so verbessert werden, dass Netzausfälle nicht mehr mit derart gravierenden und manuelle Eingriffe des Bedienungspersonals erfordernden Konsequenzen verbunden sind. Dabei kommt aber die an sich naheliegende Lösung, nämlich die Ausrüstung der Spulmaschinen mit einem konventionellen Notstromaggregat, das die gesamte Spulmaschine speist, schon aus Kostengründen nicht in Frage. Abgesehen davon, wäre ein solches Notstromaggregat wegen der hohen Spindelzahl auch zu gross und zu schwer.The invention is now to improve the known winding machines so that Power failures no longer with such serious and manual intervention by the operating personnel necessary consequences are connected. But that comes in itself obvious solution, namely equipping the winding machines with a conventional one Emergency generator that feeds the entire winder, for cost reasons alone out of the question. Apart from that, such an emergency generator would be because of the high Number of spindles too big and too heavy.

Durch die erfindungsgemässe Anordnung bleibt also der Synchronismus zwischen Spindelantrieb und Fadenchangiereinrichtung bis zum Stillstand der Spule erhalten, so dass auch während des Auslaufens der Spule eine kontrollierte Fadenverlegung erfolgt. Wenn der Netzausfall kurz ist, wobei kurz hier bedeutet, dass der Netzausfall vor dem Stillstand der Spule wieder beendet ist, dann wird er durch die Anordnung überbrückt, ist er länger, dann wird ein geordnetes Anhalten des Spulaggregats und damit der Spulmaschine ermöglicht.The arrangement according to the invention therefore maintains the synchronism between the spindle drive and thread traversing device until the bobbin comes to a standstill, so that Controlled thread laying also takes place while the bobbin is running out. If the power failure is short, where short here means that the power failure before standstill the coil is finished again, then it is bridged by the arrangement, if it is longer, then an orderly stopping of the winding unit and thus the winding machine is made possible.
Eine erste bevorzugte Ausführungsform der erfindungsgemässen Stromversorgung ist dadurch gekennzeichnet, dass bei einem Netzausfall eine Abschaltung des Spindelantriebs vom Netz erfolgt und das Stromspeichergerät bis zum Stillstand der Spindel zur Speisung der Nebenstromverbraucher dient.This is a first preferred embodiment of the power supply according to the invention characterized in that the spindle drive is switched off in the event of a power failure from the mains and the power storage device until the spindle comes to a standstill the secondary power consumer serves.
Eine zweite bevorzugte Ausführungsform der erfindungsgemässen Stromversorgung ist dadurch gekennzeichnet, dass das Stromspeichergerät durch eine statische unterbrechungslose Stromversorgung gebildet ist.A second preferred embodiment of the power supply according to the invention is characterized in that the power storage device by a static uninterrupted Power supply is formed.
Derartige statische unterbrechungslose Stromversorgungen, die als UPS (uninterruptable power supply) bezeichnet werden, sind heute beispielsweise für Computer verbreitet im Einsatz und in vielen Leistungsabstufungen und Ausführungen kostengünstig erhältlich.Such static uninterruptible power supplies, the UPS (uninterruptable power supply) are used today for computers, for example Use and available inexpensively in many performance levels and designs.
Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels und der einzigen Zeichnung näher erläutert, wobei diese Zeichnung ein Blockschema der Steuerung eines Spulstelle und der Stromversorgung der Spulmaschine zeigt. In the following the invention based on an embodiment and the only one Drawing explained in more detail, this drawing is a block diagram of the control of a The winding unit and the power supply of the winding machine shows.
In der Zeichnung bezeichnet das Bezugszeichen 1 die Stromversorgung einer Spulmaschine
und das Bezugszeichen 2 eine Spulstellensteuerung, wobei die Spulmaschine aus
bis zu 60 oder mehr Spulstellen mit Spulaggregaten besteht. Da das Spulaggregat selbst
nicht Gegenstand der vorliegenden Erfindung bildet, wird hier auf eine nähere Beschreibung
verzichtet und es wird in diesem Zusammenhang auf die EP-A-0 453 622, die EP-A-0
829 444, die EP-A-0 838 422 und auf die von der Schärer Schweiter Mettler AG vertriebene
preciflex Präzisions-Kreuzspulmaschine verwiesen.In the drawing, reference numeral 1 designates the power supply of a winding machine and
Die Spulstellen enthalten gewisse Komponenten, die zur Grundausführung gehören, sowie
gewisse optionale Komponenten, wobei in der Zeichnung die Komponenten der
Grundausführung in einem Block 2.1 und die optionalen Komponenten in einem Block
2.2 zusammengefasst sind. Die Grundausführung enthält insbesondere einen Spindelantrieb
3, einen dem Spindelantrieb zugeordneter Sensor 4 für Drehzahl und/oder Drehposition
der Spindel und damit der Spule, eine Fadenchangiereinrichtung 5, einen Sensor 6
für den Spulendurchmesser zur Durchmesserabstellung des Spindelantriebs 3, einen Fadenwächter
7 und eine vorzugsweise magnetisch betätigbare Fadendämmung 8. Dem
Spindelantrieb 3 ist ein von einem Detektor 9 zur Überwachung der Stromversorgung
betätigbarer Schalter 10 zur Unterbrechung der Stromzufuhr vorgeschaltet.The winding units contain certain components that belong to the basic design, as well
certain optional components, the components of the
Basic version in a block 2.1 and the optional components in a block
2.2 are summarized. The basic version contains in particular a spindle drive
3, a sensor 4 assigned to the spindle drive for rotational speed and / or rotational position
the spindle and thus the bobbin, a
Die im Block 2.2 zusammengefassten optionalen Komponenten umfassen beispielsweise
ein Lieferwerk 11, eine dem Lieferwerk zugeordnete Dämmung 12 und die Ölung 13 der
Spulstelle. Selbstverständlich ist die Darstellung nur als beispielhaft zu verstehen; insbesondere
kann sowohl der Block 2.1 als auch der Block 2.2 noch weitere Komponenten
aufweisen.The optional components summarized in block 2.2 include, for example
a
Die Stromversorgung 1 enthält einen Netztransformator 14, nach dessen Ausgang sich die
Speisung in zwei Pfade P1 und P2 zum Block 2.1 bzw. 2.2 teilt. Der Pfad P2 enthält einen
Wechselspannungs-/Gleichspannungswandler 15 und einen Schalter 16 und der Pfad P1
enthält einen Schalter 16', die beide im geschlossenen Zustand die Verbindung zur Speisung
herstellen und diese im geöffneten Zustand unterbrechen. Ausserdem weist der Pfad
P1 vor dem Schalter 16' eine zum Eingang einer statischen unterbrechungslosen Stromversorgung
(UPS) 17 führende Abzweigung auf. Die UPS 17, welche zwei mit den Pfaden
P1 und P2 verbundene Ausgänge aufweist, steuert die beiden Schalter 16 und 16' und
ist ausserdem zur Detektion von Netzausfällen und Abfällen der Netzspannung unter
einen bestimmten Wert ausgebildet. Die gesamte Elektronik der UPS 17 für Steuerung
und Überwachung sowie alle Schaltelemente sind in die zentrale Stromversorgung der
Spulmaschine integriert, die sich vorzugsweise in einem Schaltschrank befindet. Das
erforderliche Batteriepaket wird neben dem Schaltschrank aufgestellt oder auf diesen
aufgesetzt.The power supply 1 contains a network transformer 14, after the output of which
Dividing supply into two paths P1 and P2 to block 2.1 and 2.2 respectively. Path P2 contains one
AC /
Die Funktionsweise der beschriebenen Einrichtung ist die folgende: Die UPS 17 überwacht
die Speisung und schaltet bei Detektion eines Netzausfalls oder eines Abfalls der
Speisespannung unter einen bestimmten Pegel durch Öffnen der Schalter 16 und 16' auf
Notstromversorgung um. Der Detektor 9 der Spindelsteuerung 2 überwacht ebenfalls die
Speisung und öffnet bei Unterschreitung einer bestimmten Speisespannung den Schalter
10 und schaltet dadurch den Hauptstromverbraucher, nämlich den Spindelantrieb 3 ab.
Dieser dreht mit seiner Schwungenergie weiter. Der Detektor 4, die Fadenchangiereinrichtung
5 und alle Elemente des Fadenlaufs werden durch das UPS 17 weiter mit Strom
versorgt.The described device functions as follows: The UPS 17 monitors
the supply and switches when a power failure or a drop is detected
Supply voltage below a certain level by
Durch die Speisung des Detektors 4 und des Antriebs der Fadenchangiereinrichtung 5
durch die UPS 17 ist gewährleistet, dass der Spindelantrieb 3 ungestört auslaufen kann
und dass dabei der Synchronismus zwischen dem Spindelantrieb und der Fadenchangiereinrichtung
5 erhalten bleibt, so dass die Fadenverlegung bis zum Stillstand des Spindelantriebs
anhand der eingestellten Parameter erfolgt und auf der Spule nur die gewünschte
Wicklung hergestellt wird. Die Speisung aller Elemente des Fadenlaufs ermöglicht die
Aufrechterhaltung der gewünschten Fadenliefer- und Fadenabzugsbedingungen. Für den
Fall, dass die mit dem Spulaggregat hergestellte Spule eine so geringe Masse aufweist,
dass ihre kinetische Energie nicht ausreicht, um den Spulenantrieb ungestört auslaufen zu
lassen, wird die kinetische Energie von Spule und Spulenantrieb durch eine Zusatzmasse
vergrössert.By feeding the detector 4 and the drive of the
Die Steuerung der UPS 17 ist so ausgelegt, dass bei einem "kurzen" Abfall der Netzspannung oder einem "kurzen" Netzausfall, der noch vor dem Stillstand des Spindelantriebs 3 beendet ist, die Spulstellen der Spulmaschine wieder an das Netz geschaltet werden. Ein solcher "kurzer" Netzausfall wird anhand eines entsprechenden Zeitintervalls von beispielsweise 3 Sekunden Dauer definiert, wobei dieses Zeitintervall aber deutlich kürzer ist als die Zeit bis zum Stillstand des Spindelantriebs.The control of the UPS 17 is designed so that in the event of a "short" drop in the mains voltage or a "short" power failure that occurs before the spindle drive 3 finished, the winding units of the winding machine are switched back to the network. On Such a "short" power failure is based on a corresponding time interval of, for example 3 seconds duration defined, but this time interval is significantly shorter is the time until the spindle drive comes to a standstill.
Wenn also der Netzausfall nicht länger als 3 Sekunden dauert, dann deaktiviert sich die
UPS 17 wieder, schliesst die Schalter 16 und 16' und schaltet dadurch auf normale Speisung
um. In den Spulstellensteuerungen 2 werden die Spindelantriebe 3 wieder zugeschaltet
(Schliessen der Schalter 10) und auf ihre Solldrehzahl beschleunigt, so dass die
Spulmaschine ohne wesentlichen Zeitverlust weiterarbeitet. Ein solcher "kurzer" Netzausfall
führt also nur dazu, dass die Spulmaschine über eine kurze Zeit von wenigen Sekunden
langsamer gelaufen ist.If the power failure does not last longer than 3 seconds, then the is deactivated
UPS 17 again, closes
Dauert der Netzausfall länger als beispielsweise 3 Sekunden, dann wird der Spindelantrieb
3 nicht wieder zugeschaltet. Er wird mit seiner Schwungenergie auslaufen gelassen
und die UPS 17 speist während einer einstellbaren Zeitspanne von beispielsweise zwischen
30 und 90 Sekunden alle Nebenstromverbraucher, um so ein geordnetes Ausschalten
zu gewährleisten. Nach dieser Zeitspanne wird die UPS 17 deaktiviert und die Spulmaschine
wartet auf die Rückkehr der Netzversorgung. Sobald diese vorhanden ist, verhält
sich die Spulmaschine wie beim Einschalten mit dem Hauptschalter, d.h. die Steuerung
der UPS 17 und die Spulstellensteuerungen 2 initialisieren sich und der Fadenführer
fährt beispielsweise die beiden Endpunkte seines Changierintervalls an.If the power failure lasts longer than 3 seconds, for example, then the spindle drive
3 not switched on again. It is let out with its swing energy
and the UPS 17 feeds for an adjustable period of time, for example between
30 and 90 seconds all secondary power consumers, so an orderly shutdown
to ensure. After this period, the UPS 17 is deactivated and the winder
waiting for the power supply to return. As soon as this exists, behaves
the winding machine turns on as with the main switch, i.e. the control
