Description

Die Erfindung bezieht sich auf ein Verfahren zum Einspannen eines mit Seitenscheiben versehenen Wickeltragbaums in eine Wickelmaschine, insbesondere in eine Zettelmaschine, bei dem der Wickeltragbaum mit zwei synchron steuerbaren, jeweils an einer der Seitenscheiben angreifenden Hubeinrichtungen aus einer Bodenstellung zwischen zwei zum Angreifen an den Wickeltragbaum bestimmte Einspannwellen hochgehoben wird, bis ein Sensor das Erreichen einer Einspannstellung ermittelt und der Antrieb der Hubeinrichtungen unter Verwendung des Sensorsignals abgeschaltet wird, wonach die Einspannwellen zum Angreifen am Wickeltragbaum beaufschlagt werden.The invention relates to a method for clamping of a wrapping support tree provided with side windows into a winding machine, especially into a slip machine, where the wrap tree with two synchronously controllable, each on a lifting device engaging the side windows from a floor position between two to attack certain winding shafts are lifted up the winding support tree, until a sensor determines that a clamping position has been reached and the drive of the lifting devices using the Sensor signal is turned off, after which the clamping waves to be attacked on the winding support tree.

Ein Verfahren mit den eingangs genannten Merkmalen ist aus der DE-PS 34 36 186 und aus der US-A-3 806 058 bekannt. Es sind zwei Näherungsschalter vorhanden, die zwischen die Seitenscheiben gebracht werden. Mit diesen Näherungsschaltern wird der Wickeltragbaum so ausgerichtet, daß seine Seitenscheiben gleichen Abstand zu einer zur Achse der Einspannwellen senkrechten Symmetrieebene haben. Dieses Verfahren führt auch zum Erfolg, wenn Wickeltragbäume eingesetzt werden, die in Bezug aufeinander unterschiedliche Scheibendurchmesser haben. Es gibt Wickeltragbäume mit Scheibendurchmessern von etwa 250 bis 1400 mm. Solche unterschiedlichen Wickeltragbäume sollen eingesetzt werden können, ohne daß erhebliche Umrüstmaßnahmen an der Wickelmaschine getroffen werden müssen.A method with the features mentioned above is known from DE-PS 34 36 186 and from US-A-3 806 058. There are two proximity switches available, which are placed between the side windows. With these proximity switches, the wrap beam is like this aligned that his side windows to equal distance a plane of symmetry perpendicular to the axis of the clamping shafts to have. This procedure also leads to success when wrapping trees are used that are different in relation to each other Have disc diameter. There are wrap trees with disc diameters of around 250 to 1400 mm. Such different wrapping trees should be used can without significant retooling measures on the winding machine must be taken.

Dementsprechend liegt der Erfindung die Aufgabe zugrunde, ein Verfahren mit den Eingangs genannten Merkmalen so auszugestalten, daß es mit einfachen Verfahrensschritten durchgeführt werden kann, ohne daß aufwendige Umrüstmaßnahmen an der Wickelmaschine getroffen werden müssen.Accordingly, the invention is based on the object a method with the features mentioned above design it with simple procedural steps can be carried out without complex retrofitting measures must be taken on the winding machine.

Diese Aufgabe wird dadurch gelöst, daß der Sensor als Abstandsmesser ausgebildet ist, der den horizontalen Abstand des Wickeltragbaums überwacht, wobei gleichzeitig ein zweiter Abstandsmesser zur Überwachung des vertikalen Abstands des Wickeltragbaums eingesetzt wird, und daß die Abschaltung des Antriebs der Hubeinrichtungen erfolgt, wenn die beiden Sensormeßwerte ein vorbestimmtes Verhältnis erreicht haben.This object is achieved in that the sensor as Distance meter is formed, the horizontal distance of the wrap tree monitored, while a second Distance meter to monitor the vertical distance of the Winding support tree is used, and that the shutdown of the The lifting devices are driven when the two sensor measured values have reached a predetermined ratio.

Für die Erfindung ist von Bedeutung, daß die Stellung des Wickeltragbaums während des Einlegens bzw. während des Anhebens überwacht wird. Zur Überwachung der vertikalen Stellung dient ein Abstandssensor, der in Zusammenwirken mit einem Sensor zur horizontalen Erfassung der Stellung des Wikkeltragbaums eingesetzt wird. Wenn beide Sensormeßwerte ein vorbestimmtes Verhältnis erreicht haben, wird der Antrieb der Hubeinrichtungen abgeschaltet, weil die Sollstellung des Wikkeltragbaums erreicht ist. Das vorbestimmte Verhältnis der Meßwerte der Sensoren ist von deren Anordnung abhängig. Insbesondere gehen deren Abstand bzw. deren radiale Ausrichtung in die Auswertung der Meßergebnisse ein.It is important for the invention that the position of the wrap tree during insertion or during Lifting is monitored. For monitoring the vertical position serves a distance sensor that works in conjunction with a Sensor for the horizontal detection of the position of the winding tree is used. If both sensor readings are on have reached a predetermined ratio, the drive of the Lifting devices switched off because the target position of the winding support tree is reached. The predetermined ratio of Measured values of the sensors depend on their arrangement. In particular go their distance or their radial orientation in the evaluation of the measurement results.

Um das Verfahren im Hinblick auf die Justierung der Sensoren einfach durchführen zu können, wird so verfahren, daß der erste Sensor horizontal und der zweite Sensor vertikal zur Einspannstellung in gleichem Abstand ausgerichtet wird, und daß die Abschaltung des Antriebs der Hubeinrichtung erfolgt, wenn die beiden Sensormeßwerte gleich groß sind. Infolge des gleichen Abstands der Sensoren zur Einspannstellung des Wickeltragbaums und ihrer Ausrichtung zueinander im rechten Winkel ist das vorerwähnte vorbestimmte Verhältnis der Meßwerte 1:1.To the procedure with regard to the adjustment of the sensors To be able to carry out easily is that the first sensor horizontally and the second sensor vertically is aligned at the same distance for the clamping position, and that the drive of the lifting device is switched off, if the two sensor readings are the same size. As a result the same distance between the sensors for the clamping position of the wrap tree and their orientation to each other on the right Angle is the aforementioned predetermined ratio of Measured values 1: 1.

Die Erfindung bezieht sich auch auf ein dem eingangs genannten Verfahren ähnliches Verfahren, bei dem anstelle des Sensors ein Endschalter eingesetzt wird, dessen Endschaltersignal den Antrieb der Hubeinrichtung abzuschalten erlaubt. The invention also relates to one of the aforementioned Procedure similar procedure in which instead of Sensor a limit switch is used, its limit switch signal allows the drive of the lifting device to be switched off.

Zur Lösung der vorgenannten Aufgabe wird das Verfahren mit einem solchen Endschalter derart durchgeführt, daß außer einem als Näherungsschalter ausgebildeten Endschalter weitere Näherungsschalter parallelgeschaltet verwendet werden, die unterschiedlichen Durchmessern der Seitenscheiben des Wickeltragbaums entsprechend beabstandet werden, und daß von allen Näherungsschaltern jeweils nur einer für das Abschalten des Antriebs der Hubeinrichtungen verwendet wird.The method is used to achieve the aforementioned object performed with such a limit switch such that except a limit switch designed as a proximity switch further Proximity switches can be used in parallel different diameters of the side windows of the wrapping tree be spaced accordingly, and that of all Proximity switches only one for switching off the Drive of the lifting devices is used.

Vor dem Hochheben des Wickeltragbaums wird eine Auswahl unter den einander parallelen Näherungsschaltern dahingehend getroffen, daß derjenige scharf geschaltet wird, dessen Positionierung der gewünschten Stellung des Wickeltragbaums entspricht. Eine derartige manuelle Einstellung an der Wickelmaschine ist ein geringfügiger Verfahrensschritt, der die universelle Verwendbarkeit der Wickelmaschine bei den eingangs beschriebenen unterschiedlichen Wickeltragbäumen praktisch nicht beschränkt.A selection is made before lifting the wrap tree under the parallel proximity switches hit that the one is armed, whose positioning corresponds to the desired position of the winding support tree. Such manual adjustment on the winding machine is a minor procedural step that is universal Usability of the winding machine at the beginning described different wrapping trees practically not limited.

Das vorgenannte Verfahren kann so durchgeführt werden, daß der Näherungsschalter für das Abschalten des Antriebs der Hubeinrichtungen mit einem Wahlschalter ausgewählt wird. In diesem Fall wird also das Scharfschalten der Näherungsschalter manuell durchgeführt, was problemlos ist, wenn an unterschiedlichen Stellungen des Wahlschalters beispielsweise die Durchmesser der Seitenscheiben angegeben sind.The aforementioned method can be carried out that the proximity switch for switching off the drive of the Lifting devices with a selector switch is selected. In in this case the arming of the proximity switches performed manually, which is easy if at different Positions of the selector switch, for example Diameters of the side windows are specified.

Das Auswahlverfahren der Näherungsschalter kann aber auch automatisiert werden, wenn der Näherungsschalter für das Abschalten des Antriebs der Hubeinrichtungen mit einer eine Kante einer Seitenscheibe des Wickeltragbaums erfassenden optoelektronischen Meßeinrichtung ausgewählt wird. Als optoelektronische Meßeinrichtung wird beispielsweise eine Diodenkette eingesetzt, deren Meßergebnis davon abhängt, inwieweit die einzelnen Dioden von einer Seitenscheibe des Wickeltragbaums abgedeckt werden. Die Diodenkette kann mit paralleler Lichtbündelung arbeiten, so daß eine hinreichend genaue Erfassung des Durchmessers der Seitenscheibe auch dann möglich ist, wenn diese unterschiedlichen abstand zur Diodenkette bzw. deren Sensoren haben.The selection process of the proximity switches can, however can also be automated if the proximity switch for that Switch off the drive of the lifting devices with one Edge of a side window of the winding support tree, optoelectronic Measuring device is selected. As optoelectronic The measuring device is, for example, a diode chain used, the measurement result depends on the extent to which the individual diodes from a side window of the winding support tree be covered. The diode chain can be used with parallel Light focusing work, so that a sufficiently accurate detection of the diameter of the side window is also possible is when this different distance from the diode chain or have their sensors.

Es ist durchaus möglich, daß die Seitenscheiben eines Wickeltragbaums Abmessungen aufweisen, auf die die Positionierung der Näherungsschalter nicht abgestimmt ist. Das ist z.B. der Fall, wenn die Wickelmaschine aus Kostengründen oder aus Konzeptionsgründen nur drei Näherungsschalter hat, andererseits aber mehr als drei unterschiedliche Wickeltragbäume zum Einsatz kommen sollen. In solchen Fällen kann das Verfahren so ausgeführt werden, daß die Näherungsschalter vor dem Anheben des Wickeltragbaums vertikal verstellt werden.It is quite possible that the side windows have a Wrap tree have dimensions to which the positioning the proximity switch is not tuned. This is e.g. the case when the winding machine for cost reasons or has only three proximity switches for design reasons, on the other hand but more than three different wrap trees should be used. In such cases, the procedure so that the proximity switches before the Lifting of the winding support tree can be adjusted vertically.

Die Erfindung bezieht sich auch auf ein dem eingangs beschriebenen Verfahren ähnliches Verfahren, bei dem jedoch zur Erfassung der Einspannstellung eines Wickeltragbaums kein Sensor oder Endschalter eingesetzt wird.The invention also relates to the one described above Procedure similar procedure, but for Detection of the clamping position of a winding support tree none Sensor or limit switch is used.

Ein derartiges Verfahren kann zur Lösung der oben genannten Aufgabe dahingehend durchgeführt werden, daß der Hubweg der Hubeinrichtungen fortlaufend mit einem Inkrementalgeber gemessen wird, der an eine die Inkrementalmeßwerte verarbeitende Steuereinrichtung angeschlossen ist, welche die Abschaltung der Hubeinrichtungen bewirkt, wenn die gemessene Inkrementenzahl mit einer entsprechend dem ausgewählten Durchmesser einer Seitenscheibe des Wickeltragbaums vorbestimmten Inkrementenzahl übereinstimmt.Such a method can solve the above Task to be carried out in such a way that the stroke of the lifting devices continuously with an incremental encoder is measured to a processor that processes the incremental measured values Control device is connected, which is the shutdown of the lifting devices when the measured Increment number with one corresponding to the selected one Diameter of a side window of the winding support tree predetermined Increment number matches.

Es erfolgt eine fortwährende Messung der Stellung der Hubeinrichtung während des Hubes mit großer Präzision. Aus den Meßergebnissen kann auf die jeweilige Stellung der Wikkeltragbäume geschlossen werden, wenn jedem Wickeltragbaum eine vorbestimmte Inkrementenzahl zugeordnet wird, welche die Sollstellung bzw. die Einspannstellung des Wickeltragbaums kennzeichnet. Diese Vorbestimmung der Inkrementenzahl ist eine einmalige Maßnahme bei der Einrichtung der Meßeinrichtung bzw. der Steuereinrichtung, welche den Hubweg der Hubeinrichtung fortlaufend erfaßt. Sie wirkt sich daher bei der praktischen Durchführung des Verfahrens nur dahingehend aus, daß der Wickeltragbaum bzw. sein Scheibendurchmesser durch die Steuereinrichtung erfaßt werden muß, beispielsweise durch die vorbeschriebene manuelle Auswahl mit einem Wahlschalter oder durch die automatische Erfassung mit einer optoelektronischen Meßeinrichtung.The position of the Lifting device with great precision during the stroke. Out The measurement results can be based on the respective position of the tree support trees be closed when each wrap tree a predetermined number of increments is assigned which is the Target position or the clamping position of the winding support tree indicates. This predetermination of the number of increments is one One-off measure when setting up the measuring device or the control device, which the stroke of the lifting device continuously recorded. It therefore affects the practical Implementation of the procedure only in that the wrap beam or its disc diameter through the Control device must be detected, for example by the Manual selection described above with a selector switch or through the automatic detection with an optoelectronic Measuring device.

Ein derartiger Wickeltragbaum 11 wird von der Wickelmaschine mit einem Wickel versehen, in dem eine Vielzahl von Fäden beispielsweise von einem Spulengatter zwischen die Seitenscheiben 11' auf die Baumachse 10 gewickelt wird. Damit dies geschieht, muß der Wickeltragbaum 11 aus der in Fig.1 dargestellten Bodenstellung in eine Einspannstellung 15 hochgehoben werden, welche durch die Längsachse zweier fluchtender Einspannwellen 13 der Wickelmaschine gekennzeichnet wird. Mit diesen Einspannwellen wird der Wickeltragbaum hochgehalten und angetrieben, um die Vielzahl von Fäden aufzuwickeln. Zum Hochheben des Wickeltragbaums 11 ist eine Hubeinrichtung 12 vorgesehen, die im wesentlichen aus einer motorisch angetriebenen Hubspindel 22 besteht, die an einem Maschinengestell 23 ortsfest bzw. maschinengestellfest drehbar gelagert wird. Zum Verdrehen der Hubspindel 22 ist ein Antrieb 16 vorhanden, dessen Antriebskraft von einem auf seiner Motorwelle sitzenden Antriebsrad 16' über ein z.B. als Kette ausgebildetes Kraftübertragungselement 24 auf eine mit der Hubspindel 22 drehfeste Spindelscheibe 25 übertragen wird. Infolge der auf diese Weise bewirkten Drehung der axial unverschiebbaren Hubspindel 22 wird eine Hubeinrichtung 12 je nach Drehrichtung der Hubspindel 22 angehoben oder abgesenkt. Diese Hubeinrichtung 12 besteht im wesentlichen aus einer die Hubspindel 22 umfassenden Gewindehülse 12' und einem Tragarm 12'', auf den eine Seitenscheibe 11' des Wickeltragbaums 11 gerollt wurde, wobei Halteleisten 12''' verhindern, daß der Wickeltragbaum 11 beim Anheben unbeabsichtigterweise herunterrollen kann.In Figure 1, a wrap tree 11 is shown, the there is a tree axis 10, at the ends of each a side window 11 'is attached in a conventional manner. Such one Winding support tree 11 is from the winding machine with a Provided winding in which a variety of threads, for example from a creel between the side windows 11 'is wound on the tree axis 10. For this to happen the winding support tree 11 must be from that shown in Fig.1 Floor position raised in a clamping position 15 which are aligned by the longitudinal axis of two Clamping shafts 13 of the winding machine is marked. With The winding support tree is held up by these clamping shafts and driven to wind up the plurality of threads. To the Lifting the winding support tree 11 is a lifting device 12 provided that essentially consist of a motor-driven Lifting spindle 22 exists on a machine frame 23 is fixed or rotatably mounted on the machine frame. To the Rotation of the lifting spindle 22 is a drive 16, the driving force of which sits on its motor shaft Drive wheel 16 'via e.g. trained as a chain Power transmission element 24 to one with the lifting spindle 22 rotatable spindle 25 is transmitted. As a result of on this caused rotation of the axially immovable lifting spindle 22 becomes a lifting device 12 depending on the direction of rotation the lifting spindle 22 raised or lowered. This lifting device 12 essentially consists of a lifting spindle 22 comprehensive threaded sleeve 12 'and a support arm 12' 'on the a side window 11 'of the winding support tree 11 has been rolled, retaining strips 12 '' 'prevent the wrap tree 11 can accidentally roll down when lifting.

Wenn der Wickeltragbaum 11 in die vorbestimmte Einspannstellung 15 angehoben wurde, wird der Antrieb 16 der Hubeinrichtung 12 abgeschaltet und jede Einspannwelle 13 kann in eine Konusausnehmung 27 des Wickeltragbaums 11 eingreifen, so daß dieser dadurch gespannt wird. Damit die Seitenscheiben 11' von der Hubeinrichtung 12 freikommen, kann die Abschaltung des Antriebs 16 so vorgenommen werden, daß der Wickeltragbaum 11 geringfügig unterhalb der Einspannstellung 15 angehalten wird, so daß an den Einspannwellen 13 vorhandene Konusflächen 13' im Zusammenwirken mit entsprechenden Konusflächen des Wickeltragbaums 11 dessen Anheben in die exakte Einspannstellung 15 bewirken. Es ist dann nicht erforderlich die Hubeinrichtung 12 in besonderer Weise gesteuert wieder herunterzufahren, was vorteilhaft ist, da sie dann bei ihrem Einsatz zum Abnehmen des bewickelten Wickeltragbaums 11 nicht wieder nach oben gefahren werden muß.When the winding support tree 11 in the predetermined clamping position 15 has been raised, the drive 16 of the lifting device 12 switched off and each clamping shaft 13 can in engage a cone recess 27 of the winding support tree 11, so that this is tense. So that the side windows 11 'from the lifting device 12, the shutdown can of the drive 16 can be made so that the winding support tree 11 stopped slightly below the clamping position 15 is so that 13 existing conical surfaces on the clamping shafts 13 'in cooperation with corresponding conical surfaces the winding support tree 11 lifting it into the exact clamping position 15 effect. Then it is not necessary Shutting down the lifting device 12 in a controlled manner, which is advantageous because it is then used not to remove the wound wrap tree 11 must be driven up again.

Anhand der Fig.1 und der obigen Beschreibung versteht es sich, daß die Hubeinrichtungen 12 beim Anheben des Wickeltragbaums 11 unterschiedlich hochfahren müssen, wenn der Durchmesser D der Seitenscheiben 11' unterschiedlich ist. Kleinere und größere Wickeltragbäume 11 unterscheiden sich bezüglich ihrer Seitenscheibendurchmesser D im Bereich von 250 bis 1400 mm. Dementsprechend ergeben sich Hubdifferenzen von 575 mm, auf die die Hubeinrichtungen 12 der Wickelmaschine eingerichtet werden müssen.Based on the Fig.1 and the above description, it understands themselves that the lifting devices 12 when lifting the winding support tree 11 must start up differently if the Diameter D of the side disks 11 'is different. Smaller and larger winding support trees 11 differ in terms of their side window diameter D in the range of 250 to 1400 mm. Accordingly, there are stroke differences of 575 mm to which the lifting devices 12 of the winding machine must be set up.

Fig.1 zeigt einen Näherungsschalter 20, der am Maschinengestell 23 angebracht ist und mit einem an sich bekannten Kontaktgeber 28 der Hubeinrichtung 12 zusammenwirkt, welcher derart an der Hülse 12' angebracht ist, daß er in der Nähe des Näherungsschalters 20 vorbeifährt, wenn die Hubeinrichtung 12 angehoben wird. Wird die Position des Näherungsschalters 20 so gewählt, daß der Kontaktgeber 28 genau dann in Schaltnähe zum Näherungsschalter 20 ist, wenn der Wickeltragbaum 11 in seiner Einspannstellung 15 ist, so kann ein Schaltsignal des Näherungsschalters 20 dazu benutzt werden, um den Antrieb 16 auszuschalten.1 shows a proximity switch 20 on the machine frame 23 is attached and with a known Contactor 28 of the lifting device 12 cooperates, which is attached to the sleeve 12 'so that it is nearby of the proximity switch 20 drives past when the lifting device 12 is raised. Will the position of the proximity switch 20 chosen so that the contactor 28 exactly in Switching proximity to the proximity switch 20 is when the winding support tree 11 is in its clamping position 15, one can Switching signal of the proximity switch 20 can be used to switch off the drive 16.

Im Hinblick auf mehrere unterschiedliche Durchmesser D des Wickeltragbaums 11 können weitere Näherungsschalter 21 eingesetzt werden. Die Anzahl der Näherungsschalter bestimmt sich entsprechend dem im praktischen Betrieb vorgesehenen unterschiedlichen Abstufungen der Durchmesser der Seitenscheiben 11' unterschiedlicher Wickeltragbäume 11. Es sind lediglich beispielsweise insgesamt drei Näherungsschalter 20,21 dargestellt. Tatsächlich kann deren Anzahl der tatsächlichen Abstufungsanzahl der praktisch eingesetzten Seitenscheibendurchmesser entsprechen. Die Näherungsschalter 20,21 können auch am Gestell 23 verstellbar sein, wie es durch die den Näherungsschaltern 20,21 jeweils zugeordneten Doppelpfeile angedeutet wird. Hiermit kann eine genaue Justierung erreicht werden, aber auch eine Anpassung einer geringen Anzahl von Näherungsschaltern an eine größere Vielzahl unterschiedlicher Durchmesser D von Seitenscheiben 11'.With regard to several different diameters D of the winding support tree 11 can further proximity switches 21 be used. The number of proximity switches determines according to the different provided in practical operation Gradations of the diameter of the side windows 11 'different wrap trees 11. There are only for example, a total of three proximity switches 20, 21 shown. In fact, their number may be the actual Number of gradations of the practically used side disc diameter correspond. The proximity switches 20, 21 can can also be adjustable on the frame 23, as is the case with the proximity switches 20, 21 indicated double arrows becomes. With this an exact adjustment can be achieved but also an adaptation of a small number of Proximity switches to a larger variety of different Diameter D of side plates 11 '.

Nichtdargestellterweise kann so verfahren werden, daß von den Näherungsschaltern 20,21 jeweils nur ein einziger in der Lage ist, den Antrieb 16 abzuschalten, wobei eine Auswahl vor der Inbetriebnahme der Hubeinrichtung 12 erfolgt. Die Auswahl eines Näherungsschalters, z.B. 20, kann mit einem Wahlschalter geschehen, der so viel Wahlstellungen hat, wie es Näherungsschalter gibt. Infolgedessen wird nur der ausgewählte Näherungsschalter, z.B. 20, innerhalb der im übrigen nicht dargestellten Steuereinrichtung für das Abschalten des Antriebs 16 scharf geschaltet bzw. aktiviert. Um bei der Durchführung des Einspannverfahrens auch diese manuelle Auswahl zu vermeiden, kann letztere automatisiert werden, beispielsweise mit einer Meßeinrichtung, die den Durchmesser D der Seitenscheibe 11' erfaßt, indem die Position der Kante 11'' bzw. des Außenumfangs erfaßt wird, insbesondere an dessen höchster Stelle. Die Erfassung kann auf vielfältige Weise erfolgen, z.B. durch automatisierte mechanische Abtastung, zweckmäßigerweise aber durch eine optoelektronische Meßeinrichtung, die zur Abtastung der Kante 11'' des Wickeltragbaums 11 im Fall einer Einschaltung des Antriebs 16 der Hubeinrichtung 12 vor dessen Wirksamwerden einen Meßgang durchführt und dementsprechend den zutreffenden Näherungsschalter 20,21 auswählt.Not shown can be done in such a way that only one in each of the proximity switches 20, 21 is able to turn off the drive 16, making a selection before the lifting device 12 is started up. The Selection of a proximity switch, e.g. 20, can with one Selector switch happen that has as many positions as there are proximity switches. As a result, only the selected one Proximity switches, e.g. 20, within the rest Control device, not shown, for switching off the Drive 16 armed or activated. To at the Carrying out the clamping procedure also this manual selection to avoid, the latter can be automated, for example with a measuring device, the diameter D the side window 11 'is grasped by the position of the edge 11 '' or the outer circumference is detected, in particular on its highest place. The capture can be done in a variety of ways take place, e.g. through automated mechanical scanning, but expediently by means of an optoelectronic measuring device, those for scanning the edge 11 '' of the winding support tree 11 in the case of activation of the drive 16 of the lifting device 12 performs a measuring cycle before it takes effect and accordingly the applicable proximity switch 20.21 selects.

Auf die vorbeschriebenen Weisen kann auch verfahren werden, wenn nicht Näherungsschalter 20,21 eingesetzt werden, sondern wenn der Hubweg der Hubeinrichtungen 12 fortlaufend mit einem Inkrementalgeber gemessen wird. Dem maximal möglichen Meßweg, vgl.z.B. in Fig.2 ymax, wird eine Anzahl von Inkrementen zugeordnet, die groß genug ist, um die Position des Wickeltragbaums im Hinblick auf die Positionierung in der Einspannstellung 15 genau genug erfassen zu können. Außerdem wird in der Steuereinrichtung, welche die Messung des Hubwegs durchführt, eine Programmierung auf vorbestimmte Inkrementalwerte vorgenommen, wozu beispielsweise eine selbstprogrammierbare Steuerung eingesetzt wird. Die Programmierung erfolgt derart, daß unterschiedlichen Seitenscheibendurchmessern D jeweils diejenigen Inkrementalzahlen zugeordnet werden, die gewährleisten, daß der Wickeltragbaum 11 die gewünschte Einspannstellung 15 erreicht hat.It is also possible to proceed in the manner described above if proximity switches 20, 21 are not used, but if the stroke of the lifting devices 12 is measured continuously with an incremental encoder. The maximum possible measuring path, cf. e.g. in FIG. 2 y max , is assigned a number of increments which are large enough to be able to detect the position of the winding support tree precisely enough with regard to the positioning in the clamping position 15. In addition, programming to predetermined incremental values is carried out in the control device which carries out the measurement of the stroke, for which purpose a self-programmable control is used, for example. The programming is carried out in such a way that different side disc diameters D are assigned those incremental numbers which ensure that the winding support tree 11 has reached the desired clamping position 15.

Fig.2 erläutert ein besonderes Verfahren, bei dem die Position des Wickeltragbaums 11 meßtechnisch erfaßt wird. Es ist ein Abstandssensor 17 vorhanden, der horizontal ausgerichtet ist und einen Meßwert x ermittelt. Außerdem ist ein Abstandsmesser 18 vorhanden, der vertikal angeordnet ist und einen Meßwert y liefert. Die Sensoren 17,18 sind im rechten Winkel zueinander angeordnet und ihre Meßbereiche überschneiden sich im Bereich der Einspannstellung 15 des Wickeltragbaums 11. Da der Abstandsmesser 17 vertikal oberhalb des Wikkeltragbaums 11 angeordnet ist, liefert er stets einen Meßwert y, während der horizontal messende Abstandsmesser 17 vor dem Hochheben des Wickeltragbaums 11 einen Meßwert ∞ angibt. Erst wenn die Baumachse 10 in den Meßbereich des Abstandsmessers 17 gelangt, ermittelt dieser einen Meßwert etwa xe. Dieser Wert hat ein Maximum, wenn die Baumachse 10 die Einspannstellung 15 exakt erreicht hat. FIG. 2 explains a special method in which the position of the winding support tree 11 is measured. There is a distance sensor 17 which is oriented horizontally and determines a measured value x. There is also a distance meter 18 which is arranged vertically and provides a measured value y. The sensors 17, 18 are arranged at right angles to one another and their measuring ranges overlap in the area of the clamping position 15 of the winding support tree 11. Since the distance meter 17 is arranged vertically above the winding support tree 11, it always provides a measured value y, while the horizontally measuring distance meter 17 indicates a measured value ∞ before lifting the winding support tree 11. Only when the tree axis 10 reaches the measuring range of the distance meter 17 does it determine a measured value of approximately x e . This value has a maximum when the tree axis 10 has reached the clamping position 15 exactly.

Da die beiden Abstandsmesser 17,18 gleich weit von der Einspannstellung 15 entfernt sind, ist bei Gleichheit der Meßwerte xe und ye die Einspannstellung 15 genau erreicht. Das Verhältnis dieser Meßwerte ist 1:1. Es kann auch anders sein, wenn beispielsweise die Distanzen der Abstandsmesser 17,18 von der Einspannstellung 15 aus konstruktiven Gründen unterschiedlich sind, oder wenn die Abstandsmesser 17,18 aus konstruktiven Gründen nicht rechtwinklig zueinander angeordnet werden können.Since the two distance meters 17, 18 are equidistant from the clamping position 15, the clamping position 15 is exactly reached if the measured values x e and y e are identical. The ratio of these measurements is 1: 1. It can also be different if, for example, the distances of the distance meters 17, 18 from the clamping position 15 are different for structural reasons, or if the distance meters 17, 18 cannot be arranged at right angles to one another for structural reasons.
